[0045] The sewage is discharged into the interior of the sewage treatment tank 1 through the sewage inlet 2, and the sewage is filtered by the filter box 6. The large-particle sundries filtered down can be concentrated by the slidably arranged partition plate 7. During the sliding process of the partition plate 7, the elastically arranged cleaning plate 15 is driven to clean the side wall of the filter box 6 to prevent the sundries from blocking the filter holes.

Embodiment

[0046] As Figures 2 - 3 shown, the flocculation device for sewage treatment disclosed in the second embodiment of the present utility model has basically the same structure as that in the first embodiment, and the differences are as follows:

[0047] A motor that matches is fixedly arranged at the central position of the top of the sewage treatment tank 1, and the output end of the motor passes through the top of the sewage treatment tank 1 and is fixedly connected to a stirring barrel 4, and the stirring barrel 4 rotates inside the sewage treatment tank 1 through the motor;

[0048] Flocculant storage tanks 5 that match are arranged at both sides of the top of the sewage treatment tank 1 corresponding to the stirring barrel 4;

[0051] The size of the partition plate 7 matches the internal size of the filter box 6, and guide blocks 16 that match are fixedly arranged at the positions of both side walls of the partition plate 7 corresponding to each of the guide grooves 12. The partition plate 7 is slidably arranged inside the filter box 6 through the cooperation of the guide grooves 12 and the guide blocks 16;

[0052] Sink grooves 13 are opened on both side walls of the partition plate 7, and multiple groups of the sink grooves 13 are provided, and the multiple groups of the sink grooves 13 are evenly spaced between two adjacent guide blocks 16;

[0053] A cleaning plate 15 that matches is inserted into each of the sink grooves 13, and a second return spring 14 that matches is fixedly arranged between the side wall of the cleaning plate 15 and the inner wall of the corresponding sink groove 13. The cleaning plate 15 is in contact with the inner wall of the corresponding filter box 6 through the cooperation of the second return spring 14;

[0054] The sewage is discharged into the interior of the sewage treatment tank 1 through the sewage inlet 2, and the sewage is filtered through the filter box 6. The filtered sewage is then mixed with a flocculant by the flocculant storage tank 5. After the addition of the flocculant, the mixture is stirred by the filter box 6 and then discharged through the sewage outlet 3. The large particulate impurities filtered out can be concentrated by the slidably arranged partition plate 7. During the sliding process of the partition plate 7, the elastically arranged cleaning plate 15 is driven to clean the side wall of the filter box 6 to prevent the impurities from blocking the filter holes. Embodiment

[0055] As Figures 4 - 6 shown, the flocculation device for sewage treatment disclosed in Embodiment 3 of the present utility model has basically the same structure as that in Embodiment 2, and the difference lies in that:

[0056] A groove 18 is formed in the bottom of the filter box 6, and a matching placement plate 19 is arranged inside the groove 18;

[0057] A matching storage rod 17 is fixedly arranged at the position corresponding to the placement plate 19 at the bottom of the filter box 6. The inside of the storage rod 17 communicates with the groove 18, and a matching fourth return spring 30 is fixedly arranged at the position corresponding to the storage rod 17 at the bottom of the placement plate 19. The placement plate 19 is elastically arranged inside the filter box 6 through the cooperation of the fourth return spring 30;

[0058] A limiting groove 28 is formed in one side wall of the placement plate 19, and a matching second receiving groove 25 is formed in the inner side wall of the filter box 6 at the position corresponding to the limiting groove 28. A matching limiting block 27 is inserted into the second receiving groove 25. A matching third return spring 26 is fixedly arranged between the end of the limiting block 27 and the inner wall of the second receiving groove 25. The limiting block 27 is elastically inserted into the limiting groove 28 through the third return spring 26;

[0059] A second inclined surface 29 is formed on the upper end surface of one end of the limiting block 27 facing the limiting groove 28;

[0060] A matching first receiving groove 20 is formed in the inner bottom end of the filter box 6 at the position corresponding to the limiting block 27, and a matching clamping block 21 is slidably inserted into the first receiving groove 20;

[0061] A matching first inclined surface 22 is formed on the top of the clamping block 21 at the position corresponding to the partition plate 7;

[0062] A relief hole 23 is formed between the interiors of the first storage groove 20 and the second storage groove 25, and a matching drawstring 24 is arranged inside the relief hole 23. Two ends of the drawstring 24 are respectively connected to the limit block 27 and the clamping block 21;

[0063] During the sliding process of the partition plate 7, large-particle sundries accumulated inside the filter box 6 are concentrated above the placement plate 19. When the slidably arranged partition plate 7 moves above the clamping block 21, the clamping block 21 drives the elastically arranged limit block 27 to move through the drawstring 24. At this time, the elastically arranged placement plate 19 can drive the large-particle sundries to rise, facilitating cleaning by personnel. Embodiment

[0064] As Figure 2 shown, the flocculation device for sewage treatment disclosed in the fourth embodiment of the present utility model has basically the same structure as that in the third embodiment, and the difference lies in:

[0065] A through hole 11 is formed at a position of the partition plate 7 corresponding to the sewage inlet 2;

[0066] A matching fixing frame 8 is fixedly arranged on a side wall of the partition plate 7 at a position corresponding to the through hole 11. The fixing frame 8 has a "C"-shaped structure, and a matching baffle 9 is slidably arranged inside the fixing frame 8. A matching baffle 9 is arranged between a side wall of the baffle 9 and the inner wall of the fixing frame 8;

[0067] During the sliding process of the partition plate 7, the sewage inlet 2 will gradually move out of the through hole 11. When the sewage inlet 2 moves out of the through hole 11, the slidably arranged baffle 9 is ejected under the action of the first return spring 10 and blocks the through hole 11 to prevent sundries inside the filter box 6 from flowing out.

[0068] The specific solution of this scheme is: sewage is discharged into the interior of the sewage treatment tank 1 through the sewage inlet 2, and the sewage is filtered by the filter box 6. The filtered sewage is then mixed with a flocculant by the flocculant storage tank 5, stirred by the filter box 6 after the addition of the flocculant, and then discharged through the sewage outlet 3. The filtered large-particle sundries can be concentrated by the slidably arranged partition plate 7. During the sliding process of the partition plate 7, the elastically arranged cleaning plate 15 is driven to clean the side wall of the filter box 6 to prevent sundries from blocking the filter holes;

[0069] When the slidably arranged partition plate 7 moves above the clamping block 21, the partition plate 7 presses down the clamping block 21. At this time, the clamping block 21 drives the elastically arranged limit block 27 to move through the drawstring 24. At this time, the elastically arranged placement plate 19 can drive the large-particle sundries to rise.

[0070] Those of ordinary skill in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present utility model (including the claims) is limited to these examples; within the concept of the present utility model, the technical features in the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations in different aspects of the present utility model as described above, which are not provided in detail for the sake of brevity.

[0071] The present utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
