AI Technical Summary
After the existing wastewater solid-liquid separation system treats hazardous waste liquids, when solid-liquid suspension is filtered through the filter screen, the filter slag cannot be cleaned in time, resulting in the filter screen needing regular replacement and high maintenance costs.
A wastewater solid-liquid separation system including a spiral filter and a guide dragon rotatingly connected to the center is designed. Through the design of the spiral filter, the filter slag is washed to the center of the filter, and the guide dragon rotates and pushes it to the waste slag pool to achieve the separation of waste water and waste slag, and the filter net is exposed through a bracket, which facilitates the cleaning of artificial high-pressure water gun.
It effectively reduces the maintenance cost of solid-liquid separation system, avoids filter clogging, makes cleaning more convenient, and improves the operating efficiency of the system.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of hazardous waste treatment equipment and relates to a wastewater solid-liquid separation system. Background Art
[0002] After the hazardous waste liquid reacts with medicine and forms solid-liquid suspension. Currently, the existing method is to directly filter through a filter screen. The filter residue cannot be cleaned in time, and the filter screen needs to be replaced regularly. The hazardous waste treatment pool has a large sewage treatment volume, and the operation of replacing the screen is difficult and the operation procedure is also relatively complex. Content of the Utility Model
[0003] The purpose of the utility model is to provide a wastewater solid-liquid separation system for the above problems existing in the current technology. The technical problem to be solved by the utility model is how to reduce the maintenance cost of the solid-liquid separation system.
[0004] The purpose of the utility model can be achieved by the following technical solutions: A wastewater solid-liquid separation system, characterized in that it includes a reaction tank, a wastewater tank and a waste residue tank. A separation device is arranged at the edge of the wastewater tank. The separation device includes a spiral filter screen and a feeding auger rotatably connected to the central position of the spiral filter screen. The solid-liquid mixture in the reaction tank enters the inlet of the spiral filter screen from the notch on the wall of the reaction tank. The end of the feeding auger is connected to the waste residue tank. The water outlet notch on the wall of the reaction tank is located above the wastewater tank.
[0005] Further, a bracket is fixedly arranged on the wall of the reaction tank, and the filter screen is placed on the bracket.
[0006] The wastewater reacts in the reaction tank, and the reacted solid-liquid mixture enters the filter screen from the inlet of the filter screen. Since the filter screen is spiral and the diameter gradually decreases, and the feeding auger is located at the central position of the filter screen, the filter residue is washed to the central position of the filter screen, that is, the feeding auger. The feeding auger rotates and pushes the waste residue into the waste residue tank, and the wastewater after filtering the residue directly enters the wastewater tank, so as to realize the separation of wastewater and waste residue.
[0007] In this way, the filter screen not only realizes filtration, but also due to its spiral structure, under the guiding action of the filter screen, the filter residue is pushed towards the central position of the filter screen by the flushing water, so the filter screen is not easily blocked. In addition, since the filter screen is placed on the bracket and is in an exposed state, it is convenient for people to clean the filter screen by using a high-pressure water gun. Compared with the traditional flat filter screen, the cleaning is more convenient. Description of the Drawings
[0008] Figure 1 is the structural schematic diagram of the solid-liquid separation system.
[0009] Figure 2 is the transverse sectional view of the solid-liquid separation system.
[0010] Figure 3 It is a schematic structural diagram of a spiral filter screen and the material guiding auger inside it.
[0011] In the figure, 1 is the reaction tank; 2 is the wastewater tank; 3 is the waste residue tank; 4 is the spiral filter screen; 5 is the material guiding auger; 6 is the bracket. Specific embodiments
[0012] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.
[0013] As Figure 1 、 Figure 2 and Figure 3 shown in the wastewater solid-liquid separation system, which includes a reaction tank 1, a wastewater tank 2 and a waste residue tank 3. A separation device is provided at the edge of the wastewater tank 2. The separation device includes a spiral filter screen 4 and a material guiding auger 5 rotatably connected to the central position of the spiral filter screen 4. The solid-liquid mixture in the reaction tank 1 enters the inlet of the spiral filter screen 4 from the notch on the wall of the reaction tank 1. The end of the material guiding auger 5 is connected to the waste residue tank 3. The water outlet notch on the wall of the reaction tank 1 is located above the wastewater tank 2. A bracket 6 is fixedly provided on the wall of the reaction tank 1, and the filter screen is placed on the bracket 6.
[0014] The wastewater reacts in the reaction tank 1. After the reaction, the solid-liquid mixture enters the filter screen from the inlet of the filter screen. Since the filter screen is spiral and the diameter gradually decreases, and the material guiding auger 5 is located at the central position of the filter screen, the filter residue is washed to the central position of the filter screen, that is, the material guiding auger 5. The material guiding auger 5 rotates to push the waste residue into the waste residue tank 3, and the wastewater after filtering the residue directly enters the wastewater tank 2, thus realizing the separation of wastewater and waste residue.
[0015] In this way, the filter screen not only realizes filtration. Due to its spiral structure, under the guiding action of the filter screen, the filter residue is pushed by the flushing water towards the central position of the filter screen, and thus the filter screen is not easily blocked. In addition, since the filter screen is placed on the bracket 6 and is in an exposed state, it can be cleaned well by manually using a high-pressure water gun to flush the filter screen. Compared with the traditional flat filter screen, it is more convenient to clean.
[0016] The specific embodiments described herein are only examples to illustrate the spirit of the present invention. Those skilled in the technical field to which the present invention belongs can make various modifications or supplements to the described specific embodiments or use similar methods to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
