Description

Technical Field

[0001] The utility model relates to the technical field of waste treatment, in particular to a solid-liquid separation device suitable for water-containing waste. Background Art

[0002] Industrial production and human life generate large amounts of mixed solid-liquid waste. Left untreated, these wastes can cause serious environmental pollution. For example, the direct discharge of untreated mixed solid-liquid wastewater can pollute water bodies, clog rivers, and damage the ecological environment. Because wastewater treatment and solid waste treatment are two distinct processes, separation of the solids and liquids is often necessary before treating mixed solid-liquid waste. This facilitates the subsequent targeted treatment and recycling of the solids and liquids, thereby improving resource utilization and reducing treatment costs.

[0003] The patent with publication number CN214808938U discloses a garbage disposal device for environmental protection engineering, which realizes the movement of two racks by pulling the push-pull rod. The movement of the rack drives the gear to rotate, and the rotation of the gear drives the rotation of the cam. The rotation of the cam drives the pressure plate to move upward. When the cam continues to rotate, the pressure plate moves downward under the action of gravity. The repeated cycle realizes the up and down reciprocating movement of the pressure plate to drive the filter plate to move up and down, thereby achieving the up and down shaking of the garbage on the upper end of the filter plate, and finally achieving the separation of liquid garbage and solid garbage through inertia. However, the solid-liquid separation process in this patent solution only separates solids and liquids by vibration, which often results in a large amount of liquid remaining in the separated solids and cannot achieve the ideal solid-liquid separation effect, thereby affecting subsequent processing and utilization.

[0004] Therefore, how to provide a solid-liquid separation device with better separation effect on solid-liquid mixed waste has become one of the important technical problems to be solved urgently in this field. Utility Model Content

[0005] The technical problem to be solved by this technical solution is how to provide a device that can efficiently separate solid-liquid mixed waste.

[0006] In order to solve the above technical problems, the present technical solution provides a solid-liquid separation device suitable for aqueous waste, which comprises: a box body, a first horizontal extrusion mechanism, a first sieve plate, a lifting plate, a vertical extrusion mechanism, a second horizontal extrusion mechanism, a second sieve plate and a sealing plate, wherein the interior of the box body is divided into a unidirectional extrusion area on one side of the upper part, a liquid screening area below the unidirectional extrusion area, a bidirectional extrusion area beside the unidirectional extrusion area and the liquid screening area, and a liquid storage area below the liquid screening area and the bidirectional extrusion area according to position and function, a feed port communicating with the outside world is provided at the top of the unidirectional extrusion area, the first horizontal extrusion mechanism is provided on the side wall of the unidirectional extrusion area to push the aqueous waste fed through the feed port toward the bidirectional extrusion area, the first sieve plate is horizontally provided at the bottom of the unidirectional extrusion area and is provided with a plurality of mesh holes, and the unidirectional extrusion area is passed through the first sieve plate. The lifting plate is connected to the liquid screening area and can be moved up and down between the unidirectional extrusion area and the bidirectional extrusion area. The unidirectional extrusion area and the bidirectional extrusion area can be connected or disconnected by raising or lowering the lifting plate. The vertical extrusion mechanism and the second horizontal extrusion mechanism are respectively arranged on the two adjacent side walls of the bidirectional extrusion area to perform horizontal and vertical bidirectional extrusion on the water-containing waste pushed through the unidirectional extrusion area. The second sieve plate is vertically arranged on the side wall between the bidirectional extrusion area and the liquid screening area and is provided with a plurality of sieve holes. The bidirectional extrusion area is connected to the liquid screening area through the second sieve plate. The sealing plate is openably arranged on the side wall of the bidirectional extrusion area. The sealing plate is opened to take out the waste with water squeezed out of the bidirectional extrusion area. A liquid inlet communicating with the liquid screening area is provided on the upper part of the liquid storage area. The waste liquid screened by the first sieve plate and the second sieve plate enters the liquid storage area through the liquid screening area and the liquid inlet. Thus, the first horizontal extrusion mechanism pushes the water in the water-containing waste, which is easier to squeeze out. The lifting plate is then raised to push the water-containing waste with more difficult-to-remove water into the bidirectional extrusion zone. The vertical extrusion mechanism and the second horizontal extrusion mechanism then push the remaining water to the maximum extent possible, effectively improving the solid-liquid separation of the water-containing waste. The water discharged during the extrusion process can be collected in the liquid storage area through the screening area for subsequent targeted waste liquid treatment. Opening the sealing plate allows the waste, after the water has been squeezed out, to be removed for subsequent targeted solid waste treatment.

[0010] As another embodiment of this technical solution, both ends of the press seat and the press plate, adjacent to and away from the lifting plate, are formed with curved surfaces that gradually converge from bottom to top toward the center of the press seat and the press plate. Thus, aqueous waste pushed into the bidirectional extrusion zone through the unidirectional extrusion zone can slide along the curved surfaces to the bottom of the bidirectional extrusion zone after falling onto the upper portion of the press seat or the press plate.

The second drive telescopic cylinder 61 drives the second push plate 62 to approach or move away from the second sieve plate 7. In addition, combined with Figure 2As shown, the solid-liquid separation device may also include a lifting mechanism, which is composed of a fixed seat 41 and a third driven telescopic cylinder 42.

Accordingly, while the driving motor 57 drives the vertical extrusion mechanism 5 to operate, the sieve plate cleaning mechanism 8 can be synchronously driven to clean the first and second sieve plates 3 and 7, so as to reduce the risk of the first and second sieve plates 3 and 7 being blocked, and ensure that the solid-liquid separation process is carried out continuously and efficiently, thereby improving the reliability and stability of the operation of the solid-liquid separation device.

[0028] Accordingly, the solid-liquid separation device of the present invention can first remove the water that is easier to squeeze out of the water-containing waste by pushing it with the first horizontal squeezing mechanism, and then raise the lifting plate to push the water-containing waste with residual water that is more difficult to remove into the two-way squeezing area. Then, through the multi-directional squeezing of the vertical squeezing mechanism and the second horizontal squeezing mechanism, the residual water can be removed to the maximum extent, thereby effectively improving the solid-liquid separation effect of the water-containing waste.
