Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an interception device for wastewater treatment. Background Technology

[0002] Before entering the treatment system, wastewater often carries a large amount of floating solids, suspended solids, and large debris. If this debris enters the wastewater pipes or treatment equipment directly, it can easily cause blockages, affecting the normal discharge and treatment efficiency of the wastewater. Therefore, in the initial stage of wastewater treatment, interception devices need to be installed to intercept these debris.

[0003] The present publication number CN220090707U discloses an interception device for sewage treatment in a sewage treatment tank, comprising a sewage tank, wherein a U-shaped support plate is installed on the front and rear walls of the right side of the sewage tank, the U-shaped support plate has an opening facing downward and an interception frame is provided inside for vertical sliding connection, a lifting device connected to the interception frame is installed on the upper part of the U-shaped support plate, and a movable seat is installed on the upper end of the sewage tank on the left side of the U-shaped support plate for sliding connection, and a holding cart is slidably connected to the upper end of the movable seat.

[0004] While the above solution offers many advantages, it also has the following drawbacks: When the interception frame is at the bottom of the drainage ditch, garbage will accumulate below the sloping surface on the front side of the interception frame due to the water flow. When the interception frame rises to retrieve the garbage, the garbage accumulated on the front side of the interception frame will accumulate on the bottom front side of the interception screen plate due to the water flow. When the interception frame returns to the bottom of the drainage ditch after retrieving the garbage, the previously accumulated garbage and the garbage just intercepted during the retrieval process will be squeezed into the interception frame and the bottom of the ditch, making it impossible to retrieve. After multiple operations, the garbage accumulates more and more, affecting the filtration efficiency of the interception screen plate and the use of the interception device. Summary of the Invention

[0005] The purpose of this invention is to provide an interception device for sewage treatment, so as to solve the problem that garbage accumulates at the bottom of the retrieval bucket in the prior art, affecting the use of the interception device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sewage treatment interception device, comprising a drainage trough, a U-shaped support plate fixedly connected inside the drainage trough, an interception screen plate fixedly connected to the rear side inside the drainage trough, two movable blocks arranged inside the U-shaped support plate, a retrieval frame rotatably mounted between the two movable blocks, a front baffle hinged to the bottom front end of the retrieval frame, a drain plate slidably connected to the bottom rear end of the retrieval frame, fixed shells fixedly connected to the inner sides of both walls of the retrieval frame, and first sliding rods slidably connected to the inner sides of both side walls of the retrieval frame. The retrieval frame, the front baffle, and the drain plate together form a retrieval bucket. The retrieval frame, the front baffle, and the drain plate are all provided with screen holes so that sewage flows out from the retrieval bucket during retrieval.

[0007] Preferably, a gear is rotatably installed inside the fixed shell, and racks are meshed at both ends of the gear. One end of each rack passes through the front and rear ends of the fixed shell and is slidably connected to the fixed shell. A fourth spring is fixedly installed inside each of the two fixed shells. One end of each rack located on the rear side of the two fixed shells is respectively attached to the two fourth springs. A protrusion is fixedly connected to the rear end of each of the two fixed shells.

[0008] Preferably, each of the two fixed shells is fixedly connected to one side with a spring cylinder, and each of the two spring cylinders is slidably connected to a second slide rod. Each of the two second slide rods is provided with a first spring at one end. The two ends of the two first springs are respectively attached to the two spring cylinders and the two second slide rods. Each of the two second slide rods is fixedly connected to a fixing block at the end away from the first spring. The bottom of each of the two fixing blocks is fixedly connected to the drain plate.

[0009] Preferably, each of the two fixing blocks has a slidably connected limit hook inside, and each of the two limit hooks has a second spring fixedly connected to its top. The ends of the two second springs away from the limit hooks are respectively fixedly connected to the two fixing blocks. Each of the two racks passing through the rear side of the two fixing shells has a slot at one end, and the two slots are respectively adapted to the two limit hooks. The front ends of the two limit hooks are set as bevels.

[0010] Preferably, transmission blocks are fixedly connected to both sides of the top of the front baffle, and second sliders are fixedly connected to one side of the front end of each of the two first slide rods. The two second sliders are slidably connected to the inside of the two transmission blocks, and first sliders are fixedly connected to one side of the rear end of each of the two first slide rods. Limiting grooves are provided on both inner walls of the U-shaped support plate. The two first sliders are adapted to the two limiting grooves respectively. The movement of the first sliders in the limiting grooves drives the first slide rods to move back and forth, thereby causing the front baffle to flip with the hinge between the front baffle and the retrieval frame as the axis. When the retrieval frame is at the bottom of the drainage ditch, the top of the front baffle flips to the rear of the retrieval frame, preventing excessive accumulation of garbage in front of the retrieval bucket.

[0011] Preferably, a third spring is fixedly installed inside each of the two movable blocks, and a pull rod is fixedly installed at one end of each of the two third springs. One end of each of the two pull rods passes through the two fixed shells and slides in contact with the two fixed shells. A limit plate is provided at the bottom of one end of each of the two pull rods, and one side of the bottom of each of the two limit plates is fixedly connected to both sides of the retrieval frame.

[0012] Preferably, the U-shaped support plate has limit rods fixedly connected to both inner walls, and first threaded rods rotatably installed on both inner sides of the U-shaped support plate. Two first motors are fixedly connected to the top of the U-shaped support plate, and the output ends of the two first motors are respectively fixedly connected to the two first threaded rods. The two first threaded rods pass through two moving blocks and are threadedly connected to the two moving blocks. Second threaded rods are rotatably installed on both top sides of the drainage ditch, and a collection platform is threadedly connected to the outer sides of the two second threaded rods. Two second motors are fixedly connected to both top sides of the drainage ditch, and the output ends of the two second motors are respectively fixedly connected to the two second threaded rods. A collection vehicle for collecting garbage is placed on top of the collection platform for convenient garbage transportation.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. During the descent of the dredging bucket in this application, the first slider moves backward along the direction of the chute. The first slider pulls the second slider to move through the first sliding rod, thereby causing the front baffle to flip, so that when the front baffle is at the bottom of the drainage chute, the garbage will not accumulate on the front side of the front baffle.

[0015] 2. The front baffle of this application flips and pushes the rack on the front side of the fixed shell to move, thereby opening the bottom rear side of the retrieval frame. This prevents the garbage intercepted by the intercepting screen plate from being pressed down by the descending retrieval bucket, accumulating more and more, clogging the intercepting screen plate, and affecting the use of the device. After the retrieval bucket moves to the bottom of the drainage ditch, the limiting hook is disengaged from the slot by the protrusion, thereby closing the bottom rear side of the retrieval frame under the action of the first spring force, preventing garbage from leaking out of the retrieval bucket when it rises.

[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: Figure 1 - Figure 3 As shown, this utility model provides a technical solution for an interception device for sewage treatment, including a drainage trough 1. A U-shaped support plate 2 is fixedly connected inside the drainage trough 1. An interception screen plate 3 is fixedly connected to the rear side inside the drainage trough 1. Two moving blocks 21 are arranged inside the U-shaped support plate 2. A retrieval frame 4 is rotatably installed between the two moving blocks 21. A front baffle 5 is hinged to the bottom front end of the retrieval frame 4. A drain plate 6 is slidably connected inside the bottom rear end of the retrieval frame 4. Fixed shells 11 are fixedly connected to the inner sides of both walls of the retrieval frame 4. First sliding rods 7 are slidably connected inside the inner sides of both walls of the retrieval frame 4. The retrieval frame 4, the front baffle 5, and the drain plate 6 together form a retrieval bucket. Screen holes are opened in the retrieval frame 4, the front baffle 5, and the drain plate 6 so that sewage flows out from the retrieval bucket during retrieval.

[0025] like Figure 3 - Figure 6 As shown, a gear 12 is rotatably installed inside the fixed shell 11. Both ends of the gear 12 are meshed with racks 13. One end of each rack 13 passes through the front and rear ends of the fixed shell 11 and is slidably connected to the fixed shell 11. A fourth spring 29 is fixedly installed inside each of the two fixed shells 11. One end of each rack 13 located on the rear side of the two fixed shells 11 is in contact with the two fourth springs 29. A protrusion 20 is fixedly connected to the rear end of each of the two fixed shells 11.

[0026] Each of the two fixed shells 11 is fixedly connected to one side with a spring cylinder 14. Each of the two spring cylinders 14 is slidably connected to a second slide rod 15. Each of the two second slide rods 15 is provided with a first spring 16 at one end. The two ends of the two first springs 16 are respectively attached to the two spring cylinders 14 and the two second slide rods 15. Each of the two second slide rods 15 is fixedly connected to a fixing block 17 at the end away from the first spring 16. The bottom of each of the two fixing blocks 17 is fixedly connected to the drain plate 6.

[0027] Both of the fixed blocks 17 are slidably connected to limit hooks 18. The top of each of the two limit hooks 18 is fixedly connected to a second spring 19. The ends of the two second springs 19 away from the limit hooks 18 are respectively fixedly connected to the two fixed blocks 17. The two racks 13 that pass through the rear side of the two fixed shells 11 are each provided with a slot. The two slots are respectively adapted to the two limit hooks 18. The front ends of the two limit hooks 18 are set as bevels.

[0028] like Figure 2 - Figure 4 As shown, transmission blocks 10 are fixedly connected to both sides of the top of the front baffle 5. A second slider 9 is fixedly connected to one side of the front end of each of the two first slide rods 7. The two second sliders 9 are slidably connected to the inside of the two transmission blocks 10. A first slider 8 is fixedly connected to one side of the rear end of each of the two first slide rods 7. Limiting grooves are opened on both inner walls of the U-shaped support plate 2. The two first sliders 8 are respectively adapted to the two limiting grooves. The movement of the first slider 8 in the limiting groove drives the first slide rod 7 to move back and forth, thereby causing the front baffle 5 to flip with the hinge between the front baffle 5 and the retrieval frame 4 as the axis. When the retrieval frame 4 is at the bottom of the drainage trough 1, the top of the front baffle 5 flips to the rear side of the retrieval frame 4 to prevent too much garbage from accumulating in front of the retrieval bucket.

[0029] A third spring 22 is fixedly installed inside each of the two movable blocks 21. A pull rod 23 is fixedly installed at one end of each of the two third springs 22. One end of each pull rod 23 passes through the two fixed shells 11 and slides in contact with the two fixed shells 11. A limit plate 24 is provided at the bottom of one end of each of the two pull rods 23. One side of the bottom of each limit plate 24 is fixedly connected to both sides of the retrieval frame 4.

[0030] like Figure 1 - Figure 3As shown, the U-shaped support plate 2 has limit rods 26 fixedly connected to both inner walls. First threaded rods 25 are rotatably installed on both inner sides of the U-shaped support plate 2. Two first motors are fixedly connected to the top of the U-shaped support plate 2, and the output ends of the two first motors are respectively fixedly connected to the two first threaded rods 25. The two first threaded rods 25 pass through two moving blocks 21 and are threadedly connected to the two moving blocks 21. Second threaded rods 27 are rotatably installed on both top sides of the drainage trough 1. A collection platform 28 is threadedly connected to the outer sides of the two second threaded rods 27. Two second motors are fixedly connected to both top sides of the drainage trough 1, and the output ends of the two second motors are respectively fixedly connected to the two second threaded rods 27. A collection vehicle for collecting garbage is placed on the top of the collection platform 28 for convenient garbage transportation.

[0031] In use, this invention works as follows: Two first motors simultaneously drive the first threaded rod 25 to rotate, which in turn moves the moving block 21 up and down. The retrieval frame 4, the front baffle 5, and the drain plate 6 form a retrieval bucket, with its initial position located at the bottom of the drainage trough 1. The moving block 21 drives the retrieval bucket to rise, thereby retrieving the garbage intercepted by the intercepting screen plate 3. This avoids manual garbage retrieval and prevents excessive accumulation of intercepted garbage on one side of the intercepting screen plate 3, which could affect the flow rate of sewage and thus the sewage treatment efficiency.

[0032] During the descent of the retrieval bucket, the first slider 8 moves inside the chute. When the first slider 8 descends to the bottom of the chute and contacts the inclined chute, it moves backward along the chute direction. At this time, the first slider 8 pulls the second slider 9 through the first sliding rod 7. The second slider 9 is slidably connected inside the transmission block 10. The transmission block 10 follows the movement of the second slider 9, thereby driving the front baffle 5 to move and flip it over. This results in the front baffle 5 forming an inclined plane when the retrieval frame 4 is at the bottom of the drainage trough 1. At this time, the garbage flowing from the front of the drainage trough 1 to the intercepting screen 3 flows along the inclined plane of the front baffle 5 to the intercepting screen 3. The first slider 8 ensures that when the front baffle 5 is at the bottom of the drainage trough 1, garbage will not accumulate on the front side of the front baffle 5.

[0033] During the flipping of the front baffle 5, the transmission block 10 moves, pushing the rack 13 on the front side of the fixed shell 11 to move. At this time, the rack 13 drives the rack 13 on the rear side of the fixed shell 11 to move forward through the gear 12. The hook at the front end of the limiting hook 18 is located in the slot of the rack 13 on the rear side of the fixed shell 11. The rack 13 moves forward, pulling the limiting hook 18 to move the drain plate 6 forward, thereby opening the rear bottom of the retrieval frame 4. The retrieval frame 4 fits against the intercepting screen plate 3, and the retrieval bucket descends, causing the intercepting screen plate 3 to intercept the water just now. Garbage flows from the bottom of the opened drain plate 6 along the rear side of the retrieval frame 4 to the top of the drain plate 6. As the fixing block 17 moves forward, it compresses the first spring 16 via the second sliding rod 15. The rack 13 pulls the limiting hook 18, causing the inclined surface on the front of the limiting hook 18 to contact the protrusion 20. At this point, the limiting hook 18 moves upward and disengages from the slot. Under the elastic force of the first spring 16, the drain plate 6 closes the rear bottom of the retrieval frame 4, preventing garbage from leaking out of the retrieval bucket as it rises. The opening and closing of the drain plate 6 prevents the garbage just intercepted by the intercepting screen 3 from being pressed to the bottom by the descending retrieval bucket, accumulating and clogging the intercepting screen 3, thus affecting the use of the device.

[0034] When it is necessary to retrieve the intercepted garbage, the first motor drives the retrieval bucket to rise. At this time, the slide causes the first slider 8 to move forward, thereby flipping the front baffle 5 back to its original position. The rack 13 is always in contact with the transmission block 10 under the action of the fourth spring 29. When the rack 13 on the rear side of the fixed shell 11 moves backward and contacts the inclined surface of the front end of the limit hook 18, the fixed shell 11 pushes the limit hook 18 to move upward and compress the second spring 19. When the front end of the limit hook 18 reaches the top of the slot, the front end of the limit hook 18 re-enters the slot under the action of the second spring 19.

[0035] When the retrieval bucket moves to the upper part of the U-shaped support plate 2 and contacts the limiting rod 26, the retrieval frame 4 continues to rise. At this time, the rear side of the retrieval frame 4 rises and pulls the pull rod 23, causing the pull rod 23 to compress the third spring 22. At this time, the retrieval bucket begins to tilt and dump the garbage. When the retrieval bucket moves above the collection vehicle, the second motor can be operated. The second motor adjusts the position of the collection platform 28 through the second threaded rod 27 so that the collection vehicle is aligned with the dumped garbage. After dumping the garbage, the moving block 21 is lowered to put the retrieval bucket back into the bottom of the drainage trough 1. When the retrieval bucket is lowered after dumping the garbage, it flips under the action of the elastic force of the third spring 22. The limiting plate 24 on the rear side of the retrieval frame 4 follows the retrieval frame 4 and falls. When the bottom of the limiting plate 24 contacts the moving block 21, the retrieval frame 4 flips back to its original horizontal position.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
