Description

Technical Field

[0001] This utility model relates to the technical field of solid-liquid separation devices, and more specifically to a solid-liquid separation device for wastewater treatment. Background Technology

[0002] Solid-liquid separation is a crucial step in wastewater treatment, directly impacting subsequent treatment effectiveness and effluent quality. Early methods primarily relied on gravity sedimentation (such as sedimentation tanks), utilizing density differences to allow suspended solids to settle naturally. However, this approach is inefficient, requires significant space, and has limited effectiveness in removing fine particles and colloidal substances. As industrial wastewater becomes increasingly complex, traditional methods struggle to meet the demands for efficient separation.

[0003] Since the 20th century, mechanical separation technology has developed rapidly. Bar screens, as pretreatment equipment, can intercept larger floating objects; sedimentation tanks (such as vertical flow and inclined plate types) improve settling efficiency by optimizing hydraulic conditions; air flotation devices introduce microbubbles to adhere to fine suspended solids or oils, causing them to float and separate, and are particularly suitable for light impurities. For sludge dewatering, centrifuges utilize the centrifugal force generated by high-speed rotation to achieve rapid solid-liquid separation; belt / plate filter presses significantly reduce the moisture content of sludge through a combination of mechanical extrusion and filter media (filter cloth).

[0004] Existing solid-liquid separation devices filter solids out of liquids using a filter screen. However, prolonged filtration can cause the filter screen to become clogged. Furthermore, to ensure filtration efficiency, the filter screen is often fixed in place. Therefore, existing equipment does not allow for quick cleaning of the filter screen after prolonged filtration. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a solid-liquid separation device for sewage treatment to solve the problems existing in the background art.

The filter cylinder assembly includes a flow-through cylinder body, an aggregate guide block fixedly connected to the bottom of the inner side of the flow-through cylinder body, a drain pipe fixedly connected to the bottom of the aggregate guide block, a positioning flange fixedly connected to one side of the outer side of the drain pipe, support legs fixedly connected to the four corners of the bottom of the flow-through cylinder body, positioning grooves opened on both sides of the flow-through cylinder body, positioning plates fixedly connected to the front and back sides of the inner side of the flow-through cylinder body, and a convex sliding groove opened on the side of the positioning plate away from the flow-through cylinder body.

[0007] Furthermore, the first filter assembly includes a first filter screen, a first sealing plate is fixedly connected to one side of the first filter screen, a first handle is fixedly connected to one side of the first sealing plate, a connecting positioning block is fixedly connected to the other side of the first filter screen, and a first convex sliding plate is fixedly connected to both the front and back of the first filter screen.

[0009] Furthermore, the bottom of the polymer guide block is provided with a drainage hole, and the diameter of the drainage hole of the polymer guide block is the same as the diameter of the inner side of the drainage pipe.

[0010] Furthermore, the cross-sectional dimensions of the first convex sliding plate and the second convex sliding plate are the same, and there is a clearance fit between the cross-sectional dimensions of the second convex sliding plate and the cross-sectional dimensions of the convex sliding groove.

[0011] Furthermore, the length, width, and thickness of the connecting positioning block are fitted with the length, width, and depth of the connecting positioning groove with a clearance fit.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. In the operation of this utility model, the separated liquid is injected into the inner side of the main body of the flow cylinder through the guide pipe, and then filtered through the first and second filter screens, which can effectively separate the solids in the liquid. After being filtered through three sets of first and second filter components with different filter mesh sizes, the liquid is then polymerized by the polymer guide block, and the filtered wastewater can be discharged through the drain pipe, thus enabling the rapid discharge of filtered wastewater from the equipment.

[0014] 2. In this invention, after the filter screen becomes clogged, the bolts positioning the first and second filter components can be removed, allowing the first and second filter components to be pulled out of the filter cylinder assembly along the first and second convex sliding plates. The filtered solids can then be removed, and the first and second filter screens can be cleaned. After cleaning, the first and second convex sliding plates are inserted into the inner side of the convex sliding groove, and the connecting positioning block enters the connecting positioning groove, thus completing the cleaning and installation of the first and second filter components. This allows users to quickly clean the equipment and makes it convenient for them to use. Attached Figure Description
