Description

Technical Field

[0001] This utility model relates to the field of sludge scraper technology, specifically a novel non-metallic chain plate sludge scraper. Background Technology

[0002] A sludge scraper is a device used for sludge removal from sedimentation tanks. It scrapes the sludge deposited at the bottom of the tank towards the central sludge collection trough using scraper blades, and then discharges it out of the tank through the sludge discharge pipe. At the same time, it can also remove scum from the surface of the tank, ensuring the normal operation of the sedimentation tank and the quality of the effluent, and removing the sludge deposited at the bottom of the tank to prevent sludge accumulation from affecting the function of the sedimentation tank.

[0003] When using a chain-driven scraper to scrape sludge, adjusting the chain tension often requires completely emptying the sedimentation tank before adjustment, resulting in relatively slow overall efficiency and cumbersome operation. Therefore, it is necessary to design a sludge scraper that is easy to adjust the chain tension for maintenance and repair. Utility Model Content

[0004] The purpose of this utility model is to provide a novel non-metallic chain plate scraper to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a sedimentation tank and scrapers. A pair of drive chains, made of high-grade plastic, are installed inside the sedimentation tank. The scrapers are equidistantly fixed between the drive chains. A collection trough is provided at the end of the sedimentation tank. A pair of bottom tracks are fixed at the bottom of the sedimentation tank. Track blocks adapted to the bottom tracks are fixed on the scrapers. A drive shaft, a transmission sprocket, and an adjusting sprocket are installed inside the sedimentation tank. A pair of drive sprockets are fixed on the drive shaft. The drive chains are installed between the transmission sprocket, the drive sprocket, and the adjusting sprocket. The adjusting sprocket is rotatably connected to an adjusting shaft. The adjusting shaft is slidably connected inside the sedimentation tank via an adjusting assembly. Limiting grooves are provided on the side wall of the sedimentation tank at positions aligned with both ends of the adjusting shaft. Both ends of the adjusting shaft are slidably connected within the limiting grooves.

[0006] Preferably, the adjustment assembly includes a drive box, a traction rope, and a push-pull plate. The push-pull plate is fixed on the adjustment shaft and symmetrically distributed outside the adjustment sprocket. The drive box is fixed on the top of the sedimentation tank. A winch is installed inside the drive box. The traction rope is installed between the output end of the winch and the push-pull plate.

[0007] Preferably, a fixing plate is fixed at the bottom of the sedimentation tank and at a position corresponding to the push-pull plate, the traction rope passes through the fixing plate, a return spring is fixed between the fixing plate and the push-pull plate, and a guide wheel is installed on the side wall of the sedimentation tank between the drive box and the push-pull plate.

[0008] Preferably, a drive motor is fixed at the upper end of the sedimentation tank and at a position corresponding to the drive shaft, a drive sprocket is fixed at the output end of the drive motor, a driven sprocket is fixed on the drive shaft, and a transmission chain is installed between the drive sprocket and the driven sprocket.

[0009] Preferably, the drive chain consists of a chain body, chain links, pins, sleeves, and locking rings. The chain body and chain links are connected at their ends, and a sleeve is inserted at the connection point. The sleeve is rotatably connected to both the chain body and chain links. The pin passes through the sleeve, and one end of the pin is fixed by the locking ring.

[0010] Preferably, a skimming pipe is installed in the sedimentation tank, the upper end of the skimming pipe has a suction hole, the end of the skimming pipe is fixed with a discharge pipe, and a drive pump is fixed on the discharge pipe at the upper end of the sedimentation tank.

[0011] Compared with the prior art, the beneficial effects of this utility model are: by using the drive chain to drive the scraper to circulate, the sediment at the bottom of the sedimentation tank can be continuously scraped away and collected in the collection tank. Furthermore, by using the pull of the traction rope, the tension of the chain can be quickly adjusted without entering the sedimentation tank for adjustment, thus reducing the difficulty of operation.

A limiting groove 52 is opened on the side wall of the sedimentation tank 1 at the position aligned with both ends of the adjusting shaft 51. Both ends of the adjusting shaft 51 are slidably connected in the limiting groove 52. A skimming pipe 8 is installed in the sedimentation tank 1. A suction hole 83 is opened at the upper end of the skimming pipe 8. A discharge pipe 81 is fixed at the end of the skimming pipe 8. A drive pump 82 is fixed on the discharge pipe 81 at the upper end of the sedimentation tank 1. A drive motor 7 is fixed at the upper end of the sedimentation tank 1 at the position corresponding to the drive shaft 3. A drive sprocket 71 is fixed at the output end of the drive motor 7. A driven sprocket 72 is fixed on the drive shaft 3. A transmission chain 73 is installed between the drive sprocket 71 and the driven sprocket 72.

[0019] The adjustment assembly includes a drive box 6, a traction rope 61, and a push-pull plate 53. The push-pull plate 53 is fixed on the adjustment shaft 51 and is symmetrically distributed outside the adjustment sprocket 5. The drive box 6 is fixed on the top of the sedimentation tank 1. A winch is installed inside the drive box 6. The traction rope 61 is installed between the output end of the winch and the push-pull plate 53. A fixing plate 62 is fixed at the bottom of the sedimentation tank 1 and at a position corresponding to the push-pull plate 53. The traction rope 61 passes through the fixing plate 62. A return spring 63 is fixed between the fixing plate 62 and the push-pull plate 53. A guide wheel 64 is installed on the side wall of the sedimentation tank 1 and between the drive box 6 and the push-pull plate 53.

[0020] The drive chain 2 consists of a chain body 21, chain links 22, pins 23, sleeves 24 and locking rings 25.

[0021] Working principle: First, the entire device is connected to an external power source. Then, the drive motor 7 drives the drive sprocket 71 to rotate. Through the driven sprocket 72 and the transmission chain 73, the drive shaft 3 rotates, which in turn drives the drive sprocket 31 to rotate. Finally, the drive chain 2 drives the drive shaft 2, allowing the scraper 9 to push the sediment from the bottom of the sedimentation tank 1 into the collection tank 11 for centralized treatment and discharge. When the scraper 9 slides at the bottom of the sedimentation tank 1, it is limited by the track block 91, and the scraper 9 will move linearly along the bottom track 12, increasing the pushing force of the sediment. The stability is ensured by the use of a winch in the drive box 6 to drive the traction rope 61 to wind and unwind. During winding, the push-pull plate 53 will slide when the return spring 63 is compressed, and vice versa. The return spring 63 will reset the push-pull plate 53, which will simultaneously drive the adjusting shaft 51 and the adjusting sprocket 5 to slide and extend, thereby adjusting the tension of the drive chain 2. The whole process can be completed without entering the sedimentation tank 1. The floating sludge in the skimming pipe 8 can be discharged by the drive pump 82, and the floating matter on the water surface can be sucked into the skimming pipe 8 through the suction hole 83.
