Mechanical screen and Rainwater machinery coarse grid decontamination machine reverse fishing grid
Brief description:
Rainwater mechanical coarse grid decontamination machine Reverse fishing grid is a kind of special equipment for water treatment, which can continuously and automatically intercept and remove various shapes of debris in the fluid. It can be widely used in urban sewage treatment, drainage station, water supply industry, power plant intake, and also can be used as the front screening equipment in the wastewater treatment process of textile, food processing, paper making, leather and other industries It is one of the effective solid-liquid screening equipment.
Rotary grid cleaner, It is a kind of special water treatment equipment that can continuously and automatically intercept and remove various shapes of debris in the fluid. It can be widely used in urban sewage treatment, drainage station, water supply industry, power plant intake, and also can be used as wastewater treatment process in textile, food processing, papermaking, leather and other industries At present, the former stage screening equipment is widely used and is one of the effective solid-liquid screening equipment.
Working principle:
Rotary grid cleaning machine is a unique rake teeth assembled into a group of rotary grid chain. Driven by the motor reducer, the rake teeth chain rotates against the water flow direction.
When the harrow chain is transported to the upper part of the equipment, there is a guide of plum wheel and curved rail, which makes the relative self-cleaning movement between each group of harrow teeth. Most of the solid materials fall freely under the action of gravity, and the other part cleans up the debris stuck on the harrow teeth by the reverse movement of the sweeper.
According to the direction of water flow, the harrow chain is similar to the grid. The clearance of the harrow teeth assembled on the shaft of the harrow chain can be selected according to the service conditions. When the harrow teeth separate the solid suspended solids and floating solids in the fluid, the water flow can be ensured. The whole process can be continuous or intermittent.
Model expression:
The characteristics and application of reverse bailing grid of rainwater mechanical coarse grid decontamination machine are as follows
The advantages of the device are as follows:
(1) It has a certain self purification ability, smooth movement and no noise;
(2) There is no clogging phenomenon, so it is very suitable to make the fine grid decontamination machine with the spacing of 1 ~ 10 mm, and the effect of using the medium and coarse grid decontamination machine with the spacing of 10 ~ 20 mm in actual production is also very satisfactory;
(3) Due to the support of the rake hook, the intercepted dirt will not fall, and it is easy to remove the dirt when the top is turned over;
(4) It has the advantages of high automation, high separation efficiency, low power consumption, no noise and good corrosion resistance. It can ensure continuous and stable operation without supervision. It is equipped with overload protection device. At the same time, it can adjust the operation interval of the equipment according to the needs to achieve periodic operation; it can also be controlled automatically according to the liquid level difference between the front and the back of the grid, and has the manual control function to facilitate maintenance, so the daily maintenance workload is very small.
In view of the above advantages, it can be widely used in: debris screening of municipal pipes and canals, pre screening of sewage treatment, water intake of water supply plant and cooling water intake of power plant, pre screening of textile, printing and dyeing, chemical, tanning, papermaking, wine making and other wastewater treatment, so as to prevent blocking the water pump.
Application
For all kind of municipal and industrial wastewater pre-treatment.
Protect the structure downstream against large objects which could create obstructions in some of the facility's units,
Easily separate and remove large matter carried along by the raw water, which might negatively affect the efficiency of later treatment procedures or make their implementation more difficult.
Note:
1. The parameters with * in the upper right corner of the table should be given by the user;
2. When the channel width is more than 1600mm, parallel connection is adopted. At this time, a driving device with two grids is used, and the effective grid width is B2 = b0-320;
3. A rotary cleaning brush can be set at the back of the equipment to further remove the dirt remaining on the rake teeth. If you need to configure the cleaning brush, please indicate when ordering.
Description of necessary parameters for model selection:
Channel width (b), channel depth (H), Zui high water level (H1), grid spacing (b), material requirements, other standard configuration without requirements.
