Equipment structure
fack.. Thr racl is meinly used to support and fix other components. The surface of the rack is treated with anti-corrosion to mrelong the service life. Electromechanical control system: Control the orderly operation of all components of the equipment,caple mperutiol,convenient management, manpower saving, There is a fault alarm system to ensure the normal operation of the emuimment, rubber filter belt; a ring shaped rubber filter belt with a skirt is used to prevent the liquid from flowing out fhan borh sides, the skirt adopts a combined structure, that is, a corrugated skirt and a parallel tape bonded together; Vacuum Paoel: I is the collection point of the filtrate on the bottom surface of the drainage tape. Its center line should coincide mith the center line of the drainage belt and the center row hole. The section of the vacuum panel is U-shaped, and the material is made of carrosion-resistant materials; feeding device: the machine adopts a folding plate feeding hopper, so that the slurry is evenly distributed on the filter belt; It is composed of five-way electronically controlled slide valve and induction switch. Its function is to correct the deviation of the filter cloth. The principle is to correct the deviation of the filter cloth by changing the angle of the deviation correction roller., so that the filter belt is regeneratively cleaned after the slag is unloaded every time it is filtered, so as to ensure a better filtration rate and service life of the filter belt;Drainage tank: relying on the liquid gravity to overcome the vacuum suction. Seal with liquid,
Work process
After the slurry enters the hopper, it is evenly distributed on the filter cloth, and the driving roller drives the rubber belr and the filter cloth to rotate synchronously. During the forward transport of the slurry, under the action of vacuum neg atiwe pressure, the liquid in the slurry penetrates The filter cloth enters the vacuum chamber through the channel on the rubber belt, and then enters the drain tank through the pipe connected to the lower part of the vacuum chamber, and then is discharged through the drain tank. The filter cake formed by the slurry is removed by a scraper. After the filter cake is remored. The filter cloth passes through the cleaning device, and is recycled after washing, so that it circulates back and farth and works continuously. During the operation of the equipment, the deviation correction device ensures that the filter cloth does not deviate. The tension device adjusts the tension of the rubber belt through the screw to ensure sufficient friction. If the material needs to be washed, it can be washed through the washing bucket installed on the equipment.
Working principle
The ring shaped tape is driven by the motor to run continuously through deceleration, and the filter cloth is laid on the tape to run synchronously with it. The tape is in sliding contact with the vacuum chamber (there is an annular friction belt between the vacuum chamber and the tape, and water is introduced to form a water seal). When the vacuum chamber is connected to the yacuum system, a vacuum filtration area is formed on the tape; the slurry is evenly distributed by the distributor On the filter cloth, under the action of vacuum, the filtrate passes through the filter cloth and is collected by the horizontal groove on the tape and enters the vacuum chamber through the small hole, and the solid particles are trapped to form a filter cake; the liquid entering the vacuum is discharged through the gas-water separator . With the movement of the rubber belt,the formed filter cake enters the filter cake washing area and the drying area in turn; finally, the filter cloth is separated from the tape, and the filter cake is discharged at the filter cake discharge roller; Regeneration is obtained; after passing through a set of backup rollers and a deviation correction device, it re-enters the filtration area.
Introduction of main components
1. Rubber filter belt: The annular rubber filter belt with skirt is used to prevent the liquid from flowing out from both sides; The skirt of this structure has good elasticity, which can prevent the skirt from breaking through the direction of the roller, and can effectively prevent the slurry from leaking. The upper part of the rubber filter belt is constructed as a middle row of drainage grooves. as a drainage belt. There is a drainage groove in the middle of the groove, and the rubber filter belt is the key component of the belt filter; its lifespan generally depends on the choice of rubber material and on-site maintenance. Therefore, the material of the rubber filter belt is determined according to the properties of the msterial. For field installation, flat tape must be installed first to allow it to function properly before bonding the corrugated skirt. And the cleaning of the tape must be ensured to slow down the aging of the rubber when the equipment is runing. To prolong the service life of the tape, it must be noted that the belt filter should not be used for materials that are strongly corrosive to rubber.
2. Driving wheel: The driving wheel is the driving wheel that drives the running of the belt. It is made of steel drum covered with acid-resistant rubber. It is controlled by a variable frequency governor and driven by a motor (adjustable within the range of 0-50Hiz). The reducer decelerates at low speed. Rotate, or decelerate by the variable frequency governor through the planetary cycloid reducer, the friction between the tensioned tape and the rubber layer drives the tape and the filter cloth to move continuously, and the filter cake is discharged at the turning point of the filter cloth..
3. Vacuum pane!; Ths mcuun panel is the collection point of the filtrate on the bottom surface of the drainage tape. Its center line should coincids with the center line of the drain belt and the center drain hole. The cross-section of the vacuum panel is"Y" shape, and the material is made of corrosion-resistant materials. The vacuum panel is stationary while the filter is running.The adhesive tape runs on it, and the vacuu panel is connected in sections to form a whole, and each section has a noazle connected to the liquid collection main pipe to form a vacuu liquid collection system. A ring-shaped friction belt is designed between the vacuum box and the running belt; and it is sealed with water (the friction belt runs on the friction block on the vacuum panel with the belt), and the water can be used as both a lubricant and a coolant for the sealing device, forming Very effective vacuum seal the annular friction belt moves with the tape, keeping the horizontal tape free from abrasion. Although the ring-shaped friction belt is lubricated by water when running on the slider, it still wears and needs to be replaced after a certain period of time. In order to facilitate the replacement of the friction belt, the ring-sheped friction belt is designed as a replaceable structure,and a lifting mechanism is also designed for the vacuum panel; to make it When replacing, the vacuum panel is at a low position,which is conducive to the convenience and quickness of replacing the friction belt.
4. Pashing device: It is used to add washing liquid, and there are generally two forms: (1) The washing device is used for the occasiea that need to be washed by the liquid column replacement method, and its structure adopts the sawtooth grid of the overflow meiw senerally used for this purpose). Dwring installation, the rinsing device and the filter belt must be kept horizontally hori.aod the water can overflow evenly in each serrated nouth to ensure that the washing water is evenly distributed on the surfacv cf the filter cake; (2) Spraying device: used for spraying and turning In the case of washing, the washing liquid needs a cer tain pressure, and the sprayed washing liquid is in the shape of a flat fan. When installing, the nozzle is 100um away from the filter cake, and the spraying direction should be ad justed to be consistent. The above two forms can be mixed and matched.
5. Scraper device: When the filter cake runs to the discharge wheel, the filter cake is easier to peel off the filter belt due to its curvature, and then the filter cake is peeled off and discharged with a thin plate scraper or a wire scraper. The scraper is made of polypropylene (or hard polyethylene), which has the advantages of wear resistance and elasticity.
