Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a sedimentation tank for wastewater treatment. Background Technology

[0002] A sedimentation tank for wastewater treatment is a structure that uses the principle of gravity settling to remove suspended particles from wastewater and is an important component of wastewater treatment systems.

[0003] Chinese Patent Publication No. (CN221557804U) discloses a sedimentation tank for wastewater treatment, including a sedimentation tank body, a drain valve, a filter scraper assembly, and auxiliary components. The filter scraper assembly includes a reciprocating screw, a sliding sleeve, a motor, a support frame, and a filter screen. The sliding sleeve is sleeved around the reciprocating screw, and the support frame is fixed to the bottom of the sliding sleeve by bolts. The auxiliary components include a first slide rail and a second slide rail. The first slide rail is disposed on the inner wall of the sedimentation tank body corresponding to the top of the reciprocating screw, and the second slide rail is disposed on both sides of the inner wall of the sedimentation tank body through reserved grooves.

[0004] The aforementioned comparative document describes a method that uses a motor to drive a reciprocating screw to rotate, thereby causing the sliding sleeve support frame, along with the filter screen, to scrape and filter the sediment in the sedimentation tank. This method can remove sediment to a certain extent. However, as the usage time increases, a large amount of sediment will accumulate on the surface of the filter screen, requiring cleaning. However, in the existing technology, the support frame is set inside the sedimentation tank, the filter screen is installed inside the support frame, and the reciprocating screw is installed on the top of the support frame. This structural design makes it impossible to remove the support frame from the inside of the sedimentation tank, making cleaning the filter screen relatively inconvenient and increasing maintenance difficulty and cost.

[0005] In view of this, the present invention solves the above-mentioned technical problems by proposing a sedimentation tank for sewage treatment. Utility Model Content

[0006] To address the shortcomings of the aforementioned background technology, this utility model provides a technical solution for a sedimentation tank for wastewater treatment. A guide groove is formed at the bottom of the sedimentation tank body, and a guide block is slidably connected within the guide groove. The top of the guide block has a circular hole. Simultaneously, a locking assembly is installed on the surface of the reciprocating screw and the guide rod. When the support frame needs to be removed, the locking pin is pulled upwards to disengage it from the inner cavity of the support frame. The locking pin is then rotated so that its cylindrical surface engages with the inner cavity of the baffle, thus fixing the locking pin. Subsequently, the support frame is rotated 90 degrees and lifted upwards, allowing for convenient removal of the support frame. This simplifies the filter cleaning process, reduces maintenance costs, and improves wastewater treatment efficiency.

[0007] This utility model provides the following technical solution: a sedimentation tank for sewage treatment, comprising: a sedimentation tank body, a support frame, a filter screen, a reciprocating screw, and a motor;

[0008] The bottom of the inner cavity of the sedimentation tank body is provided with a guide groove, and a guide block is slidably connected to the inner cavity of the guide groove. The top of the guide block is provided with a round hole.

[0009] Guide rods are fixed to the opposite surfaces of the sedimentation tank body, and locking components are slidably connected to the surfaces of the reciprocating screw and the guide rods for locking the support frame.

[0010] The locking assembly includes two sliding blocks, which are slidably connected to the surfaces of the reciprocating lead screw and the guide rod, respectively. A locking pin is slidably connected to the inner cavity of each sliding block. A rotating ring is rotatably connected inside the sliding block. A spring is fixed to the opposite surface of the rotating ring and the locking pin. A cylinder is fixed to the surface of the locking pin. A baffle is fixed to the top of the sliding block. The surface of the cylinder engages with the inner cavity of the baffle. A connecting plate is engaged with the surface of the locking pin inside the sliding block. The bottom end of the connecting plate is fixedly connected to the top end of the support frame.

[0011] As a preferred technical solution of this utility model, the front and rear surfaces of the inner cavity of the sedimentation tank body are provided with limiting grooves, the inner cavity of the limiting grooves is slidably connected to limiting blocks, and the surface of the limiting blocks is fixedly connected to the surface of the sliding blocks.

[0012] In a preferred embodiment of this invention, one end of the spring is fixedly connected to the bottom end of the locking pin, and the other end of the spring is fixedly connected to one end of the rotating ring.

[0013] As a preferred embodiment of this utility model, a handle is fixed to the top of the connecting plate.

[0014] As a preferred embodiment of this utility model, grooves are provided on both sides of the handle.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. When the filter screen needs to be cleaned, the operator can easily remove the support frame from the inner cavity of the sedimentation tank by following simple steps. This not only reduces the difficulty of operation, but also improves work efficiency and helps to ensure the continuity and stability of sewage treatment work.

[0017] 2. The design of this utility model effectively solves the problem of inconvenient filter cleaning in the prior art. Since the support frame can be easily removed, the operator can easily clean the surface of the filter, thereby ensuring the cleanliness and filtration efficiency of the filter and improving the quality of sewage treatment.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1,

[0025] Please see Figure 1-4As shown, a sedimentation tank for wastewater treatment includes a sedimentation tank body 1, a support frame 101, a filter screen 102, a reciprocating screw 103, and a motor 104. A guide groove 2 is provided at the bottom of the inner cavity of the sedimentation tank body 1. A guide block 201 is slidably connected to the inner cavity of the guide groove 2. A circular hole 202 is provided at the top of the guide block 201. A guide rod 3 is fixed to the opposite surface of the sedimentation tank body 1. Locking components are slidably connected to the surfaces of the reciprocating screw 103 and the guide rod 3 for locking the support frame 101. The locking components include two sliding blocks 4, which are slidably connected to the surfaces of the reciprocating screw 103 and the guide rod 3, respectively. A locking pin 401 is slidably connected to the inner cavity of each sliding block 4. A rotating ring 402 is rotatably connected inside each sliding block 4. A spring 403 is fixed to the opposite surface of the rotating ring 402 and the locking pin 401. The surface of the locking pin 401 is fixed with a locking pin 401. There is a cylinder 404, and a baffle 405 is fixed to the top of the sliding block 4. The surface of the cylinder 404 is engaged with the inner cavity of the baffle 405. A connecting plate 406 is engaged with the surface of the locking pin 401 in the inner cavity of the sliding block 4. The bottom end of the connecting plate 406 is fixedly connected to the top end of the support frame 101. Limiting grooves 5 are opened on the front and rear surfaces of the inner cavity of the sedimentation tank body 1. Limiting blocks 501 are slidably connected to the inner cavity of the limiting grooves 5. The surface of the limiting blocks 501 is fixedly connected to the surface of the sliding block 4. By setting the limiting grooves 5 and the limiting blocks 501, the limiting grooves 5 and the limiting blocks 501 are mainly used to guide and limit the sliding block 4. One end of the spring 403 is fixedly connected to the bottom end of the locking pin 401. The other end of the spring 403 is fixedly connected to one end of the rotating ring 402. A handle 6 is fixed to the top of the connecting plate 406. Grooves 7 are opened on both sides of the handle 6.

[0026] When it is necessary to remove the support frame 101, first pull the two locking pins 401 upward to disengage them from the inner cavity of the connecting plate 406. Next, rotate the locking pins 401. Since a rotating ring 402 is provided, when the locking pins 401 rotate, it will drive the spring 403 to rotate. The rotation of the spring 403 will drive the rotating ring 402 to rotate, thus preventing the spring 403 from affecting the rotation of the locking pins 401. Then, make the cylinder 404 engage with the inner cavity of the baffle 405 at its highest point to prevent the locking pins 401 from moving downward. Next, grasp the handle 6 and the groove 7, rotate the support frame 101 ninety degrees, and lift it upward to remove the support frame 101. After removing the support frame 101, remove the filter screen 102 from the inner cavity of the support frame 101 for cleaning.

[0027] When installing the support frame 101, first connect and position the bottom of the support frame 101 with the round hole 202 at the top of the guide block 201. Next, hold the handle 6 and the groove 7, and rotate the support frame 101 ninety degrees so that the connecting plate 406 rotates into the inner cavity of the sliding block 4. Then, rotate the locking pin 401 so that the cylinder 404 disengages from the inner cavity of the baffle 405. Finally, under the action of the spring 403, the locking pin 401 automatically moves downward to lock the connecting plate 406 and the support frame 101. After locking, rotate the locking pin 401 again so that the cylinder 404 engages with the inner cavity of the baffle 405 at its lowest point, thereby limiting the locking pin 401 and preventing the locking pin 401 from disengaging from the inner cavity of the connecting plate 406 when the sliding block 4 reciprocates.
