[0018] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The following will describe the present utility model in detail with reference to the drawings and in conjunction with the embodiments.

[0019] It should be pointed out that unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs.

[0020] In the present utility model, unless otherwise stated, the directions such as "upper, lower" are generally in the directions shown in the drawings, or in the vertical, perpendicular or gravitational directions; similarly, for the convenience of understanding and description, "left, right" are generally in the left and right shown in the drawings; "inner, outer" refer to the inner and outer of the contour of each component itself, but the above direction terms are not used to limit the present utility model.

[0021] Please refer to Figures 1-4 , the present utility model provides the following technical solutions:

[0022] A resin production and processing storage tank wastewater filtration device, including a housing 1, a reaction chamber 4 and a separation chamber 5 are arranged inside the housing 1, a motor 6 is installed on the housing 1, a rotating shaft 61 is connected to the output shaft of the motor 6, the rotating shaft  61 extends into the housing 1 and axially penetrates through the reaction chamber 4 and the separation chamber 5, a stirring blade 42 and an extrusion screw blade 53 are installed on the rotating shaft 61, the stirring blade 42 is arranged in the reaction chamber 4, the extrusion screw blade 53 is arranged in the separation chamber 5, a flocculant injection port 2 and a wastewater inlet 3 are arranged above the housing 1, and both the flocculant injection port 2 and the wastewater inlet 3 are communicated with the reaction chamber 4;

[0023] The flocculant and the wastewater enter the reaction chamber 4 through the flocculant injection port 2 and the wastewater inlet 3 respectively. The motor 6 drives the stirring blade 42 and the extrusion screw blade 53 to rotate synchronously. The stirring blade 42 stirs the mixture in the reaction chamber 4, promotes the reaction, and at the same time pushes the mixture towards the separation chamber 5. The mixture pushed into the separation chamber 5 is a solid-liquid mixture. The mixture is continuously pushed by the extrusion screw blade 53 in the separation chamber 5. During the movement of the mixture, the liquid leaks out, while the solid continues to be extruded and finally is extruded from the other end, realizing solid-liquid separation, thus avoiding the blockage caused by the deposition of solids in the mixture after the flocculation reaction, and at the same time facilitating the treatment of the subsequent discharged substances, improving the efficiency of wastewater treatment.

[0024] The separation chamber 5 includes a fixing frame 51. The fixing frame 51 is a mesh structure frame, which forms a cylindrical structure. A screen 52 is covered and attached to the inner side of the fixing frame 51. A slag discharge port 54 is connected to the right side of the fixing frame 51. The slag discharge port 54 is arranged coaxially with the fixing frame 51. The solids pushed by the extrusion spiral blade 53 are finally extruded and discharged from the slag discharge port 54. The extrusion spiral blade 53 is set with a smaller pitch, which increases the movement path of the mixture, ensures that the liquid in the mixture can fully pass through the screen 52, and improves the separation rate;

[0025] The outer edge of the extrusion spiral blade 53 is close to the screen 52. When the extrusion spiral blade 53 rotates, it will not wear the screen 52, but can scrape the solids adhered to the surface of the screen 52, avoiding the blockage of the screen 52 and improving the solid-liquid separation efficiency;

[0026] A drain port 12 is provided at the bottom of the outer shell 1. The liquid that falls into the outer shell 1 through the screen 52 is finally discharged through the drain port 12.

[0027] The reaction chamber 4 includes a reaction cylinder body 41. The reaction cylinder body 41 is arranged coaxially with the fixing frame 51. A discharge port 43 is connected to the side of the reaction cylinder body 41 facing the separation chamber 5. The discharge port 43 is arranged coaxially with the reaction cylinder body 41. The other end of the discharge port 43 is connected to the fixing frame 51. When the stirring blade 42 rotates in the cylinder body 41, it flips the water flow, which not only promotes the flocculation reaction but also pushes the fluid towards the discharge port 43, enabling the fluid to enter the subsequent separation chamber 5; The flocculant injection port 2 and the wastewater inlet 3 are both arranged on the side of the cylinder body 41 facing away from the separation chamber 5, which extends the reaction path and promotes the full progress of the flocculation reaction.

[0028] The wastewater inlet 3 includes a conduit 31. A top cover 11 is provided on the outer shell 1. The conduit 31 connects the top cover 11 and the reaction cylinder body 41. One end of the conduit 31 on the top cover 11 is provided with a groove, and a filter screen 34 is placed in the groove. A connecting pipe 32 is pressed on the top cover 11. The connecting pipe 32 is connected to the top cover 11 by a number of screws 33. The end of the connecting pipe 32 connected to the top cover 11 is sealed and connected to the conduit 31 and the filter screen 34;

[0029] When the wastewater enters the reaction chamber 4 through the wastewater inlet 3, the large particle impurities in it are first filtered by the filter screen 34, which improves the subsequent treatment efficiency;

[0030] The filter screen 34 is placed in the groove at the top of the conduit 31 and is sealed and fixed by the connecting pipe 32 pressed from above. When the filter screen 34 needs to be cleaned, only the screws fixing the connecting pipe 32 need to be unscrewed, and then the filter screen 34 can be taken out for cleaning, with convenient operation.

[0031] Specifically, a separation chamber 5 is connected to the rear side of the reaction chamber 4. A rotating shaft 61 passes through the reaction chamber 4 and the separation chamber 5. A stirring blade 42 and an extrusion screw blade 53 are installed on the rotating shaft 61. The stirring blade 42 is inside the reaction chamber 4, and the extrusion screw blade 53 is inside the separation chamber 5. The outermost layer of the separation chamber 5 is a fixing frame 51, which is a cylindrical body formed by a net structure. A screen 52 is covered on the inner side of the fixing frame 51. The outer edge of the extrusion screw blade 53 is close to the screen 52. A slag discharge port 54 is provided at one end of the fixing frame 51 away from the reaction chamber 4. The solid-liquid mixture after sufficient flocculation reaction in the reaction chamber 4 enters the separation chamber 5 through the discharge port 43. The mixture is pushed by the extrusion screw blade 53 towards the slag discharge port 54. The liquid therein passes through the screen 52 and enters the outer shell 1 and is finally discharged through the drain port 12, while the solid is pushed and extruded until it is discharged through the slag discharge port 54, realizing solid-liquid separation, avoiding the situation of solid deposition and blockage after the flocculation reaction, and improving the wastewater treatment efficiency.
