The hydraulic reciprocating rectangular bottom sludge scraper is a rectangular bottom sludge scraper which integrates the continuous transportation and concentration of sludge. Rectangular tank bottom scraper is dragged from the first generation steel cable to the scraper type. The second generation of vehicles took the bridge to suck the mud, the third generation of the chain scraper evolved to the present fourth generation of hydraulic reciprocating, hydraulic reciprocating rectangular bottom mud scraper with less moving parts, less maintenance, continuous sludge transport. High-quality, easy installation, sludge concentration and other characteristics. Hydraulic reciprocating bottom scraper has been successfully applied to a large number of different types of sludge sedimentation systems.
Wide range of application.
Detailed Photos
The gear oil pump provides power to the hydraulic cylinders, and a set of tripods converts the vertical motion of the cylinders into horizontal motion, and finally drives a group of wedge-shaped scrapers to reciprocate at the bottom of a rectangular pool; the reciprocating stroke is larger than the distance of a single scraper. , Equivalent to the following scraper transferring sludge to the previous scraper; the forward speed of the scraper group is approximately half of the retreat speed; when it is advanced, the concave surface of the wedge scraper pushes the mud in the front mud pool.
When receding, a small wedge-shaped acute angle will not drive the sludge to move backwards, and the negative pressure generated by the rapidly receding concave surface will keep the sludge layer of a certain thickness to the inertia of forward movement.
Therefore, when the scraper reciprocates, a layer of sludge is always moving forward until it drops into the mud ditch. When the bottom sediment reaches a certain thickness, the efficiency of the scraper is highest. The reciprocating movement of the scraper also has the effect of concentrating the sludge (up to 3%). This characteristic is highlighted in practical applications. When the amount of pollutants is equal, the higher the sludge concentration, the lower the water consumption rate, which reduces the loss of water and energy.
Product Description
Product Description
Hydraulic reciprocating mud scraper is a hydraulic reciprocating square bottom mud scraper that integrates continuous sludge transportation and concentration. The square bottom mud scraper has evolved from the first generation of wire rope traction, the second generation of traveling suction, and the third generation of chain scraper to the current fourth generation of hydraulic reciprocating. It is widely used for the scraping, concentration, and discharge of sludge in horizontal sedimentation tanks. In the renovation of old ponds, there are advantages such as small renovation amount, easy installation, and good sludge discharge effect. The hydraulic reciprocating square bottom scraper has the characteristics of fewer moving parts, less maintenance, continuous sludge transportation, uninterrupted sedimentation process, high reliability, easy installation, and sludge concentration. It has been widely used in a large number of different sludge sedimentation systems.
Product features
Product features:
1. Less moving parts, easy maintenance, and long service life; The entire system only has several components in motion during operation, including the bottom scraping system, push rod, and triangular arm frame. There is a roller rolling between the scraper and the guide rail, which has low friction when moving in water. Driving the scraper along the bottom of the pool requires less power, and the equipment operates sensitively with a long service life.
2. Continuous sludge transportation, uninterrupted sedimentation process, and high operational reliability;
3. Suitable for upgrading and renovating existing square sedimentation tanks, this model of mud scraper has reduced requirements for civil engineering renovation of deep sedimentation tanks, and is suitable for both inclined bottom or longitudinal concave convex sedimentation tanks.
working principles
operational principle
The working principle of hydraulic reciprocating mud scraper is that the wedge-shaped scraper moves forward and backward along the bottom of the pool under hydraulic power drive to scrape away sludge. When the scraper moves forward, the wedge-shaped concave surface transporting sludge is in the same direction as the sludge pit. During the return movement, the wedged point is inserted into the covered sludge layer, and the return speed is about twice the forward speed. Therefore, the sludge flows towards the sludge pit on the scraper, ensuring uninterrupted sludge transportation. When the sludge forms a sludge cover layer at the bottom of the deep sedimentation tank, the scraper moves back and forth to scrape off the sludge. When the sludge flows along the bottom of the tank, the complex movement of the scraper effectively improves the concentration process of the sludge. The scraper has the function of scraping the sludge, guiding the sewage to flow outside the sludge pit, and increasing the solid content of the deep sedimentation tank. This feature increases the solid content, reduces the amount of wastewater, and reduces water and energy losses in applications.
The dual scraper is used in square sedimentation tanks of municipal sewage plants, water plants, and industrial sewage treatment stations, and can also be combined with inclined pipes, steam floatation tanks, etc.
