Abstract
Description
Technical Field
[0001] The present application relates to the technical field of sewage treatment equipment, and specifically discloses a dirt stripping structure for a sewage treatment tank. Background Art
[0002] Sewage treatment refers to the process of purifying sewage to meet certain water quality requirements. Usually, sewage is input into the sewage treatment tank through sewage pipes for centralized treatment. The sewage treatment tank used is a special container that integrates the sewage treatment device into the box.
[0003] The sewage treatment tank is usually integrated with a dirt separation structure. Since the sewage contains dirt, the dirt separation structure can be used to remove the dirt in the sewage to achieve the purpose of preliminary water purification and prevent the dirt from clogging the pipes in subsequent processes. After the dirt is removed, it is discharged from the outlet of the sewage treatment tank.
[0004] However, most of the dirt separation structures in the prior art directly collect and discharge the dirt in a unified manner, and usually collect the dirt into a frame or filter bag. When applied to large pieces of cloth or dirt that can be attached to the surface of the frame or filter bag, the lack of a fine crushing structure for large pieces of material will cause the large pieces of dirt to clog the cavities on the surface of the frame or filter bag, and a large amount of sewage will be carried away during the discharge of the dirt, which is inconvenient to use.
[0005] Therefore, in view of this, the inventor provides a dirt stripping structure for a sewage treatment tank to solve the above problems. Utility Model Content
[0006] The purpose of the utility model is to solve the problem that the traditional sewage separation structure integrated in the sewage treatment box has no function of crushing large pieces of materials.
[0007] To achieve the above-mentioned objectives, the basic solution of the present invention provides a waste stripping structure for a sewage treatment tank, comprising a partition plate fixedly connected to the sewage treatment tank, a plurality of filter barrels fixedly connected to the partition plate at equal intervals, rotating shafts coaxially connected to the filter barrels, and a driving structure provided on one side of the sewage treatment tank and used to synchronously drive the rotating shafts to rotate. The partition plate is provided with a plurality of connecting slots for respectively inserting the filter barrels, a plurality of blades are fixedly connected to the bottom of the rotating shaft in a circumferential direction, a spiral blade extending from the top of the filter barrel is fixedly connected to the rotating shaft above the blades, and a fine crushing slot for exposing the blades is provided at the bottom of the filter barrel.
[0008] The utility model also comprises a collecting box which is arranged on the top of the sewage treatment box and covers the top of the filter barrel. The collecting box is provided with a plurality of through holes which are respectively communicated with the top of the filter barrel, and a plurality of filter holes are also provided on the bottom of the collecting box.
[0009] Furthermore, the isolation plate and the filter barrel are both arranged at an angle, and are both inclined backward along the flow direction of sewage in the sewage treatment tank.
[0010] Furthermore, a plurality of layers of blades are fixedly connected to the bottom of the rotating shaft, and the blades between adjacent layers are staggered.
[0011] Furthermore, the collection box is arranged on the side of the filter barrel facing the water outlet of the sewage treatment tank.
[0012] Furthermore, the bottom of the collection box is tilted downward from the end connected to the filter barrel to form an inclined portion, and the filter holes are opened on the inclined portion.
[0013] Furthermore, the bottom of the collecting box is bent at the end of the inclined portion to form a horizontal portion, and filter holes are also provided on the horizontal portion.
[0014] Furthermore, the filter barrel is provided with a plurality of filter holes.
[0015] The principle and effect of this solution are:
[0016] Compared with the prior art, the present invention separates the water in the sewage treatment tank through isolation plates and filter barrels, and the spiral blades are driven to rotate by the rotating shaft installed in the filter barrel, which can suck up the sewage in the sewage treatment tank and the debris contained therein, and gradually discharge them to the top of the filter barrel to be discharged into the collection box. At the same time, the blades installed at the bottom of the rotating shaft can also crush large pieces of dirt when sucking in the dirt, so that they can enter the gaps between the spiral blades and be transported to the top of the filter barrel with the water flow. Finally, the sewage containing fine dirt that reaches the collection box will be filtered through the filter holes, and the dirt will be stripped off and left in the collection box, which solves the problem that the traditional dirt separation structure integrated in the sewage treatment tank does not have the function of crushing large pieces of material.

[0020] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.
[0021] The figure marks in the drawings of the specification include: sewage treatment tank 1, water outlet 2, filter barrel 3, rotating shaft 4, blade 5, spiral blade 6, filter hole 7, inclined part 8, horizontal part 9, collection box 10, driven sprocket 11, driving sprocket 12, drive motor 13, isolation plate 14.
[0022] A dirt stripping structure for a sewage treatment tank, for example Figure 1 and Figure 2 As shown:
[0023] The system comprises a partition plate 14 fixedly mounted within the sewage treatment tank 1, a plurality of filter barrels 3 welded equidistantly to the partition plate 14, a rotating shaft 4 coaxially mounted within each filter barrel 3 and rotatable therein, and a drive mechanism mounted on the left side of the sewage treatment tank 1 for synchronously driving the rotating shaft 4. The partition plate 14 has a plurality of communicating slots for mounting the filter barrels 3.
[0024] Specifically, a water outlet 2 is opened at the left bottom of the sewage treatment tank 1. The sewage treatment tank 1 is connected to an external pipe from the right top to enter the sewage treatment tank 1. The water bodies on both sides of the sewage treatment tank 1 are separated by an isolation plate 14 and a filter barrel 3.
[0025] In this embodiment, the isolation plate 14 and filter barrel 3 are both installed at an angle, tilted backward along the direction of sewage flow within the sewage treatment tank 1, that is, tilted toward the water outlet 2. A bracket is also integrally formed on the top of each filter barrel 3. The bracket is located a section above the filter barrel 3, creating a gap between the bracket and the top of the filter barrel 3 for waste to drain. Each bracket has an axial hole. Mounting blocks are also installed on the inner bottom surface of the sewage treatment tank 1, facing the bottom of the filter barrel 3. The rotating shaft 4 is installed through the mounting block and the axial hole, respectively, with the top end of the rotating shaft 4 extending out of the axial hole.
[0026] The driving structure includes driven sprockets 11 coaxially fixedly mounted on the rotating shaft 4 located above the bracket, a support base mounted on one side of the sewage treatment tank 1, a driving motor 13 mounted on the support base, a driving sprocket 12 coaxially fixedly mounted on the output shaft of the driving motor 13, and a chain meshed between the driving sprocket 12 and the plurality of driven sprockets 11.
[0027] The bottom of the rotating shaft 4 is also circumferentially mounted with several layers of blades 5, and the blades 5 between adjacent layers are staggered. The rotating shaft 4 above the blades 5 is also fixedly mounted with spiral blades 6, and the tops of the spiral blades 6 extend to the top of the filter barrel 3. The bottom of the filter barrel 3 is also provided with a crushing slot for the blades 5 to be exposed. Specifically, the crushing slot is a semicircular arc slot, which is specifically opened on the filter barrel 3 on the right side of the sewage treatment tank 1, that is, opened towards the water body containing dirt. In this embodiment, the filter barrel 3 is also circumferentially provided with several filter holes 7, which are connected to the water bodies on both sides of the sewage treatment tank 1 through the filter holes 7, so that most of the water body can be discharged directly through the filter barrel 3, and the dirt entrained in the water body will remain in the filter barrel 3 and be transported upward by the spiral blades 6.
[0028] A collecting box 10 covering the top of the filter barrel 3 is also installed on the top of the sewage treatment tank 1, and the collecting box 10 is installed on the side of the filter barrel 3 facing the water outlet 2 of the sewage treatment tank 1, that is, the left side of the filter barrel 3. A number of through holes are opened on the collecting box 10, which are respectively connected to the top of the filter barrel 3, and a number of filter holes 7 are opened at the bottom of the collecting box 10. The sewage containing dirt brought up by the rotation of the spiral blade 6 from the top of the filter barrel 3 will be discharged into the collecting box 10, and will be filtered through the filter holes 7 at the bottom of the collecting box 10. The water will be filtered out from the filter holes 7 and fall into the sewage treatment tank 1 below and be discharged from the water outlet 2, and the dirt will be stripped off and remain in the collecting box 10.
[0029] In this embodiment, the bottom of the collection box 10, connected to the filter barrel 3, is further inclined downward to form an inclined portion 8. The distal end of the inclined portion 8 is bent to form a horizontal portion 9. Filter holes 7 are formed in the inclined portion 8 and the horizontal portion 9, respectively. When wastewater containing pollutants is discharged into the inclined portion 8, the downstream water will carry the pollutants with it and collect them in the horizontal portion 9, preventing the pollutants from accumulating at the bottom of the collection box 10 and clogging the filter holes 7.
[0030] When the utility model is used, the water body in the sewage treatment tank 1 is separated by the isolation plate 14 and the filter barrel 3, and the spiral blade 6 is driven to rotate by the rotating shaft 4 installed in the filter barrel 3, so that the sewage in the sewage treatment tank 1 and the internal debris can be sucked up and gradually discharged to the top of the filter barrel 3 to be discharged into the collection box 10. At the same time, the blade 5 installed at the bottom of the rotating shaft 4 can also crush the large pieces of dirt when sucking in the dirt, so that they can enter the gaps between the spiral blades 6 and be transported to the top of the filter barrel 3 with the water flow. Finally, the sewage containing fine dirt that reaches the collection box 10 will be filtered through the filter holes 7, and the dirt will be stripped off and left in the collection box 10.
[0031] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
