Description

Technical Field

[0001] This utility model relates to the field of sludge scrapers, specifically a reciprocating sludge scraper adjustment mechanism. Background Technology

[0002] A sludge scraper is a machine used to remove sludge from riverbeds. It is used in large-diameter circular sedimentation tanks in urban sewage treatment plants, waterworks, and industrial wastewater treatment plants to remove sludge settled at the bottom and skim off scum from the surface. The sludge scraper is mainly used in large-diameter circular sedimentation tanks in urban sewage treatment plants, waterworks, and industrial wastewater treatment plants to remove sludge settled at the bottom and skim off scum from the surface. The drive unit drives the sludge scraper to rotate around the center of the sedimentation tank. After the raw water settles in the sedimentation tank, the supernatant is discharged from the overflow weir plate. The sludge settled at the bottom of the tank is slowly pushed along the bottom of the tank to the central sludge collection trough by the logarithmic spiral curve scraper and discharged through the sludge discharge pipe. At the same time, the scum on the surface of the tank is concentrated in the area between the scum scraper and the scum baffle. When the working bridge passes the scum discharge cylinder floating on the surface of the tank, the scum discharge cylinder is pressed below the liquid surface, and the scum is discharged out of the tank through the discharge cylinder.

[0003] However, the hydraulic cylinders in most traditional reciprocating sludge scrapers are inconvenient to adjust. Since the size, sludge thickness and distribution of different sedimentation tanks may be different, a fixed stroke of the hydraulic cylinder will result in poor sludge scraping effect. For example, in areas with thicker sludge, a fixed stroke may not be able to completely scrape off the sludge, while in areas with thinner sludge, it may cause energy waste or excessive wear on the equipment. Furthermore, a fixed stroke may cause the hydraulic cylinder to consume energy in ineffective strokes, such as wasting hydraulic energy in no-load reciprocating motion, which increases operating costs. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the hydraulic cylinders in most traditional reciprocating sludge scrapers are inconvenient to adjust. Since the size, sludge thickness and distribution of different sedimentation tanks may be different, a fixed stroke of the hydraulic cylinder will lead to problems such as poor sludge scraping effect. This utility model proposes an adjustment mechanism for a reciprocating sludge scraper.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a reciprocating sludge scraper adjustment mechanism, including a sedimentation tank, a sludge discharge pit opened on the inner bottom surface of the sedimentation tank, a scraper base provided on the inner bottom surface of the sedimentation tank, a bracket fixedly connected to the top of the sedimentation tank, a hydraulic cylinder fixedly connected to the top of the bracket, a first connecting seat fixedly connected to the output end of the hydraulic cylinder, a transmission component provided in the inner cavity of the first connecting seat, and a positioning structure provided in the inner cavity of the bracket;

[0006] The positioning structure includes a sliding groove, which is formed on one side of the bracket. A positioning hole is formed on the other side of the bracket. There are multiple positioning holes. The inner wall of each positioning hole is connected to the inner wall of the sliding groove. A positioning rod is inserted into the inner wall of the positioning hole. A fixing cap is threaded onto the surface of the positioning rod. A pressure-resistant member is sleeved on the surface of the positioning rod. An elastic buffer rod is fixedly connected to one side of the pressure-resistant member. A bonding plate is fixedly connected to the other end of the elastic buffer rod.

[0007] Preferably, a limiting rod is fixedly connected to one side of the first connecting seat, the surface of the limiting rod is slidably connected to the inner wall of the groove, and the surface of the limiting rod abuts against one side of the pressure-resistant member.

[0008] Preferably, a limiting plate is fixedly connected to the surface of the positioning rod, and there are multiple limiting plates. The surface of the limiting plate is slidably connected to the positioning hole and the inner cavity of the pressure-resistant component.

[0009] Preferably, the transmission component includes a first push rod, one end of which is rotatably connected to the inner cavity of the first connecting seat, and the other end of which is rotatably connected to a triangular arm, and the inner cavity of the triangular arm is rotatably connected to a second push rod.

[0010] Preferably, the inner wall of the sedimentation tank is fixedly connected to a fixing frame, and one side of the triangular arm is rotatably connected to the inner cavity of the fixing frame.

[0011] Preferably, the scraper base includes a center plate, a second connecting seat is fixedly connected to one side of the center plate, and one end of the second push rod is rotatably connected to the inner cavity of the second connecting seat.

[0012] Preferably, a scraper body is fixedly connected to one side of the center plate, and there are several scraper bodies. A guide plate is fixedly connected to one side of each scraper body.

[0013] The advantages of this utility model are:

[0014] In this invention, the hydraulic cylinder can drive the first connecting seat to slide. The limiting rod on one side of the first connecting seat slides along the slide groove, so that the output end of the hydraulic cylinder is connected to the bracket. The positioning rod in the positioning structure can be inserted into the required positioning hole. When the limiting rod contacts the positioning rod, the output end of the hydraulic cylinder can be artificially limited. The installation of the positioning rod is fixed by the fixing cap. The anti-compression component can increase the compressive strength of the positioning rod, and the elastic buffer rod can provide a certain elastic buffer for the anti-compression component. The stability of the anti-compression component and the elastic buffer rod is increased by the bonding plate. Thus, the transmission stroke of the hydraulic cylinder can be adjusted according to the sludge in the sedimentation tank. At the same time, the scraping distance of the scraper base can be changed, which can avoid excessive wear of the scraper base and extend the service life of key components such as scraper, chain, and track. This solves the problems of the hydraulic cylinder being inconvenient to adjust in most traditional reciprocating sludge scrapers, and the fixed stroke of the hydraulic cylinder leading to poor sludge scraping effect due to the different sizes, sludge thickness and distribution of different sedimentation tanks.

[0021] 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 scope of protection of the present utility model.

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses an adjusting mechanism for a reciprocating sludge scraper. (Refer to...) Figures 1 to 4 A reciprocating sludge scraper adjustment mechanism includes a sedimentation tank 1, a sludge discharge pit 2 opened on the inner bottom surface of the sedimentation tank 1, a scraper base 6 provided on the inner bottom surface of the sedimentation tank 1, a bracket 3 fixedly connected to the top of the sedimentation tank 1, a hydraulic cylinder 4 fixedly connected to the top of the bracket 3, a first connecting seat 5 fixedly connected to the output end of the hydraulic cylinder 4, a transmission component 7 provided in the inner cavity of the first connecting seat 5, and a positioning structure 8 provided in the inner cavity of the bracket 3.

[0024] The positioning structure 8 includes a chute 801, which is located on one side of the support 3. A positioning hole 802 is located on the other side of the support 3. Multiple positioning holes 802 are provided, and their inner walls communicate with the inner wall of the chute 801. A positioning rod 803 is inserted into the inner wall of each positioning hole 802. A fixing cap 804 is threaded onto the surface of the positioning rod 803. A pressure-resistant member 805 is fitted onto the surface of the positioning rod 803. An elastic buffer rod 806 is fixedly connected to one side of the pressure-resistant member 805, and a bonding plate 807 is fixedly connected to the other end of the elastic buffer rod 806. A limiting rod 9 is fixedly connected to one side of the first connecting seat 5. The surface of the limiting rod 9 is slidably connected to the inner wall of the chute 801, and its surface abuts against one side of the pressure-resistant member 805. The sedimentation tank 1 in the reciprocating sludge scraper adjustment mechanism is used to store sludge. The hydraulic cylinder 4 drives the transmission component 7 to reciprocate and scrape the sedimentation tank 1. The sludge is discharged through the sludge discharge pit 2. The hydraulic cylinder 4 can drive the first connecting seat 5 to slide. The limiting rod 9 on one side of the first connecting seat 5 slides along the slide groove 801 so that the output end of the hydraulic cylinder 4 is connected to the bracket 3. The positioning rod 803 in the positioning structure 8 can be inserted into the required positioning hole 802. When the limiting rod 9 contacts the positioning rod 803, the output end of the hydraulic cylinder 4 can be artificially limited. The installation of the positioning rod 803 is fixed by the fixing cap 804. The pressure-resistant component 805 can increase the pressure resistance of the positioning rod 803, and the elastic buffer rod 806 can provide a certain elastic buffer for the pressure-resistant component 805. The stability of the pressure-resistant component 805 and the elastic buffer rod 806 is increased by the bonding plate 807. Thus, the transmission stroke of the hydraulic cylinder 4 is adjusted according to the sludge in the sedimentation tank 1, and the scraping distance of the scraper base 6 is changed at the same time. This can avoid excessive wear of the scraper base 6 and extend the service life of key components such as scraper, chain, and track.

[0025] Reference Figure 4 A limiting plate 10 is fixedly connected to the surface of the positioning rod 803. There are multiple limiting plates 10. The surface of the limiting plate 10 is slidably connected to the positioning hole 802 and the inner cavity of the anti-pressure member 805. Through the setting of the limiting plates 10, the multiple limiting plates 10 can limit the positioning rod 803 in the positioning hole 802, so as to avoid the positioning rod 803 from rotating in the positioning hole 802 as much as possible. At the same time, the limiting plate 10 can limit the anti-pressure member 805 to the surface of the positioning rod 803, so as to avoid the anti-pressure member 805 from rotating on the surface of the positioning rod 803 as much as possible.

[0026] Reference Figure 2The transmission component 7 includes a first push rod 701, one end of which is rotatably connected to the inner cavity of the first connecting seat 5, and the other end of which is rotatably connected to a triangular arm 702. A second push rod 703 is rotatably connected to the inner cavity of the triangular arm 702. A fixing frame 11 is fixedly connected to the inner wall of the sedimentation tank 1, and one side of the triangular arm 702 is rotatably connected to the inner cavity of the fixing frame 11. The scraper base 6 includes a center plate 601, one side of which is fixedly connected to the second connecting seat 602. One end of the second push rod 703 is rotatably connected to the inner cavity of the second connecting seat 602, and one side of the center plate 601 is fixedly connected to the scraper body 603. There are several scraper bodies 603. A guide plate 604 is fixedly connected to one side of the scraper body 603. Through the transmission component 7, the first push rod 701 in the transmission component 7 is rotatably connected to the first connecting seat 5. The hydraulic cylinder 4 pushes the first connecting seat 5 and pushes the first push rod 701 at the same time. The first push rod 701 can push the triangular arm 702 to rotate along the fixed frame 11. At the same time, the other side of the triangular arm 702 can push the second push rod 703. Since the second push rod 703 is connected to the second connecting seat 602 in the scraper base 6, the second push rod 703 can push the scraper base 6 to move back and forth, and scrape the sludge in the sedimentation tank 1 through the scraper body 603.

[0027] Working principle: The first push rod 701 in the transmission component 7 is rotatably connected to the first connecting seat 5. The hydraulic cylinder 4 pushes the first connecting seat 5 and simultaneously pushes the first push rod 701. The first push rod 701 can push the triangular boom 702 to rotate along the fixed frame 11. At the same time, the other side of the triangular boom 702 can push the second push rod 703. Since the second push rod 703 is connected to the second connecting seat 602 in the scraper base 6, the second push rod 703 can push the scraper base 6 to move back and forth. The sludge in the sedimentation tank 1 is scraped off by the scraper body 603. The scraped sludge is discharged through the sludge discharge pit 2. The hydraulic cylinder 4 can drive the first connecting seat 5 to slide. The limiting rod 9 on one side of the first connecting seat 5 slides along the slide groove 801, so that the output end of the hydraulic cylinder 4 is connected to the bracket. 3. The positioning rod 803 in the positioning structure 8 can be inserted into the required positioning hole 802. When the limiting rod 9 contacts the positioning rod 803, the output end of the hydraulic cylinder 4 can be artificially limited. The installation of the positioning rod 803 is fixed by the fixing cap 804. The anti-compression component 805 can increase the compressive strength of the positioning rod 803, and the elastic buffer rod 806 can provide a certain elastic buffer for the anti-compression component 805. The stability of the anti-compression component 805 and the elastic buffer rod 806 is increased by the bonding plate 807. Thus, the transmission stroke of the hydraulic cylinder 4 can be adjusted according to the sludge in the sedimentation tank 1, and the scraping distance of the scraper base 6 can be changed at the same time. This can avoid excessive wear of the scraper base 6 and extend the service life of key components such as scraper, chain, and track.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
