DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] Please refer to Figures 1-6 The present application provides a technical solution: a wastewater treatment device, comprising a filter tank 1, a water inlet 101 is fixedly connected to the top of the filter tank 1, a filter box 2 is slidably installed in the filter tank 1, an opening is formed in the lower end of the filter box 2, a first filter screen 202 is fixedly connected to the inner wall of the filter box 2, a filter table 3 is slidably installed inside the filter tank 1 and below the filter box 2, a filter ladder 302 is fixedly connected to the top of the filter table 3, a filter frame 4 is vertically slidably installed on one side of the filter tank 1, an extrusion block 402 is fixedly connected to the front of the filter frame 4, the extrusion block 402 cooperates with the filter box 2 and the filter table 3, and a second filter screen 401 is embeddedly installed in the filter frame 4.

[0024] In the embodiment, the sewage is delivered into the filter tank 1 through the water inlet 101, the filter box 2 is located below the water inlet 101, and then the sewage first enters the inside of the filter box 2 and is discharged from the lower end opening after being preliminarily filtered by the first filter screen 202. The preliminarily filtered sewage then falls onto the filter table 3. Since the space inside the filter tank 1 is enlarged, the flow rate of the sewage falling onto the filter table 3 is slowed down. Since the metal particles have a greater density than the clean water, the metal particles in the sewage gradually sink. The metal particles in the lower layer are intercepted by the filter steps 302, and the metal particles are further intercepted and filtered. The filter frame 4 is vertically inserted into the inside of the filter tank 1. The twice-filtered sewage is further filtered by the second filter screen 401, and the solid impurities inside are filtered as much as possible after being filtered again. The extrusion block 402 cooperates with the filter box 2 and the filter table 3 to extrude and fix the filter box 2 and the filter table 3 in the inside of the filter tank 1. When the filter screen accumulates a certain amount of impurities, the filter frame 4 is pulled out of the inside of the filter tank 1, and the fixing of the filter box 2 and the filter table 3 is released. At this time, the filter box 2 and the filter table 3 can be removed from the inside of the filter tank 1.

[0025] In order to achieve the purpose of slidingly installing the filter box 2 and the filter table 3 in the filter tank 1, the device adopts the following technical solutions: the filter tank 1 is fixedly connected with a water outlet 102 at the back, the water outlet 102 is fixedly connected with a valve, limit clamping grooves 103 are formed in the inner walls of the two sides of the filter tank 1, limit clamping blocks 201 are fixedly connected to the two sides of the filter box 2, the limit clamping blocks 201 are slidingly matched with the limit clamping grooves 103, a first displacement handle 203 is fixedly connected to the back of the filter box 2, limit sliding rails 104 are fixedly connected to the inner walls of the two sides of the filter tank 1, limit sliding grooves 301 are formed in the two sides of the filter table 3, the limit sliding grooves 301 are slidingly matched with the limit sliding rails 104, a second displacement handle 303 is fixedly connected to the front of the filter table 3, and a third displacement handle 403 is fixedly connected to the top of the filter frame 4.

[0026] The filtered sewage can be discharged through the water outlet 102. The valve is used to control the on-off of the water outlet 102, so as to control the outflow of the sewage in the filter tank 1. The limit clamping grooves 103 and the limit clamping blocks 201 are slidingly matched, so that the filter box 2 is slidingly installed in the inside of the filter tank 1. During the backward movement of the filter box 2, the top of the filter box 2 is no longer blocked by the upper end of the filter tank 1. At this time, the filter box 2 can be directly removed from the inside of the filter tank 1 by using the first displacement handle 203. The limit sliding grooves 301 and the limit sliding rails 104 are slidingly matched, and the filter table 3 is moved backward by using the second displacement handle 303. After the filter steps 302 are removed from the limit sliding rails 104, the restriction on the filter table 3 is released. At this time, the filter table 3 can be taken out of the inside of the filter tank 1. The third displacement handle 403 can be used to drive the filter frame 4 to move upward.

[0027] In order to realize the purpose of stirring sewage, the device adopts the following technical scheme: the inner wall of the filter tank 1 is fixedly connected with a support frame 5, the support frame 5 is rotatably connected with a rotating shaft 501, the rotating shaft 501 is fixedly connected with a stirring roller 502, the upper surface of the support frame 5 is fixedly connected with a power motor 503, and the output end of the power motor 503 is fixedly connected with the rotating shaft 501.

[0028] By starting the power motor 503, the rotating shaft 501 can be driven to rotate, the rotating shaft 501 can drive the stirring roller 502 to rotate, the stirring roller 502 can stir the sewage in the filter tank 1, and the treatment agent added into the sewage can be mixed together with the sewage, and the sewage can be filtered by using a chemical method.

[0029] The working principle and use process of the device are as follows: when in use, the device needs to be placed in a suitable position, sewage is conveyed into the filter tank 1 through the water inlet 101, the conveyed sewage is preliminarily filtered through the limiting clamping block 201, the sewage is discharged from the lower end opening after being preliminarily filtered through the first filter screen 202, and then falls onto the upper surface of the filter table 3, the metal particles in the sewage gradually sink, the lower metal particles are intercepted through the filter ladder 302, the metal particles are further intercepted and filtered, finally, the sewage flows to the rear section of the filter tank 1 after being filtered through the second filter screen 401, a certain amount of chemical agent can be added into the sewage in the rear end of the filter tank 1 through the exposed opening in the upper portion of the filter tank 1, the power motor 503 is started to drive the rotating shaft 501 to rotate, the rotating shaft 501 rotates to drive the stirring roller 502 to rotate, the chemical agent is stirred and mixed together with the sewage, and then the sewage is discharged from the water outlet 102.
