Description

Technical Field

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

[0002] Sedimentation tanks are structures that remove suspended solids from water using sedimentation. They are water purification devices that utilize natural sedimentation or coagulation to remove suspended solids. Sedimentation tanks are classified into horizontal and vertical sedimentation tanks based on the direction of water flow. The sedimentation effect depends on the water flow rate and residence time in the tank. To improve sedimentation efficiency and reduce land area, honeycomb inclined tube countercurrent flow sedimentation tanks, accelerated clarification tanks, and pulse clarification tanks are commonly used. Sedimentation tanks are widely used in wastewater treatment. However, sludge is generated during the sedimentation process, requiring periodic sludge scraping.

[0003] In existing sewage sedimentation tanks, sludge removal is mostly done manually, which is inconvenient, increases labor costs, and reduces work efficiency. To address this, we provide a sludge scraping device for sewage treatment sedimentation tanks. Utility Model Content

[0004] The purpose of this invention is to provide a sludge scraping device for a sedimentation tank in wastewater treatment, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] The sedimentation tank is equipped with a sludge scraping unit inside, and adjustment units are provided on both sides of the sludge scraping unit.

[0008] A further improvement of the present invention is that the adjustment unit includes telescopic support plates that are movably connected to the top of both sides of the sedimentation tank. A locking block is fixedly connected to one end of the right side of the telescopic support plate. Rollers are rotatably installed inside both ends of the telescopic support plate. The rollers can reduce resistance and improve the smoothness of movement when the telescopic support plate moves.

[0009] A further improvement of this utility model is that a fixed support column is fixedly installed at the middle position of the telescopic support plate, and electric push rods are fixedly installed on both sides of the fixed support column, with a connecting vertical plate fixedly installed on the other end of the electric push rod.

[0010] A further improvement of this utility model is that: a telescopic pusher is movably installed on the front side of the connecting vertical plate, the middle position of the telescopic pusher is movably installed on the front side of the fixed support, and fixed vertical plates are movably installed on both ends of the telescopic pusher.

[0011] A further improvement of this utility model is that: the top of the fixed vertical plate is fixedly connected to both sides of the bottom of the telescopic support plate, and a telescopic sludge scraper is fixedly installed on the bottom outer side of the fixed vertical plate. The bottom of the telescopic sludge scraper is attached to the bottom of the sedimentation tank. The bottom ends and the middle position of the telescopic sludge scraper are flush, which makes it easy to attach to the bottom of the sedimentation tank.

[0012] A further improvement of the present invention is that the sludge scraping unit includes a brake tooth plate fixedly installed on one end of the telescopic support plate, a bearing plate is fixedly installed on the outer left side of the sedimentation tank, and a motor is fixedly installed on the top of the bearing plate, so that the bearing plate can support the motor.

[0015] 1. This utility model provides a sludge scraping device for a sedimentation tank in sewage treatment. By setting a motor to drive a drive rod to make a rotating gear rotate at a constant speed, the rotating gear causes a brake tooth plate to gradually move to the other end of the sedimentation tank. The movement of the brake tooth plate causes a telescopic sludge scraper to move along with it. The telescopic sludge scraper is used to quickly scrape off the sludge settled at the bottom of the sedimentation tank, thereby improving work efficiency.

[0016] 2. This utility model provides a sludge scraping device for a sedimentation tank in wastewater treatment. By setting two sets of electric push rods to start simultaneously, it is easy to push the connecting vertical plates on both sides in opposite directions. When the connecting vertical plates move, they drive the telescopic push frame to move accordingly. At this time, the telescopic push frame moves to adjust its own length. The two ends move in opposite directions at the same time, thereby driving the fixed vertical plate to move accordingly. The fixed vertical plate drives the telescopic support plate and the telescopic sludge scraper to extend and retract simultaneously, changing its own length. It can adjust its own width according to the width of the sedimentation tank, making it suitable for sedimentation tanks of different widths and improving its applicability.

[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] like Figure 1-5As shown, this utility model provides a sludge scraping device for a sedimentation tank in wastewater treatment, including a sludge scraping device body 1. The sludge scraping device body 1 includes a sedimentation tank 2. A sludge collection box 3 is fixedly installed on the right side of the sedimentation tank 2. A sealing plate 4 is movably inserted into the inside of the right side frame of the sedimentation tank 2. A lifting ring 41 is fixedly installed on the top of the sealing plate 4. A sludge outlet 215 is opened at the bottom of the right side frame of the sedimentation tank 2. A sludge scraping unit is provided inside the sedimentation tank 2. Adjustment units are provided on both sides of the sludge scraping unit. The sludge scraping unit includes a brake toothed plate 22 fixedly installed on one end of the left side of the telescopic support plate 21. A bearing plate 211 is fixedly installed on the outer surface of the left side of the sedimentation tank 2. A motor 212 is fixedly installed on the top of the bearing plate 211. A drive rod 213 is fixedly installed on the output end of the motor 212. A rotating gear 214 is fixedly installed on the other end of the drive rod 213. The inner teeth of the rotating gear 214 mesh with the brake toothed plate 22.

[0026] Furthermore, the sewage inside the sedimentation tank is discharged out through the outlet. At this time, the output end of the motor 212 drives the drive rod 213 to cause the rotating gear 214 to rotate at a constant speed. The rotating gear 214 causes the brake tooth plate 22 to gradually move to the other end of the sedimentation tank 2. The movement of the brake tooth plate 22 causes the telescopic scraper 210 to move along with it. The telescopic scraper 210 scrapes off the sludge settled at the bottom of the sedimentation tank 2, so that it can enter the sludge collection box 3 through the sludge outlet 215.

[0027] Example 2

[0028] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the adjustment unit includes a telescopic support plate 21 that is movably connected to the top of both sides of the sedimentation tank 2. A locking block 23 is fixedly connected to one right end of the telescopic support plate 21. Rollers 24 are rotatably installed inside both ends of the telescopic support plate 21. A fixed support column 25 is fixedly installed in the middle of the telescopic support plate 21. Electric push rods 26 are fixedly installed on both sides of the fixed support column 25. A connecting vertical plate 27 is fixedly installed on the other end of the electric push rod 26. A telescopic push frame 28 is movably installed on the front side of the connecting vertical plate 27. The telescopic push frame 28 is movably installed on the front side of the fixed support column 25 in the middle. Fixed vertical plates 29 are movably installed on both ends of the telescopic push frame 28. The top of the fixed vertical plate 29 is fixedly connected to both sides of the bottom end of the telescopic support plate 21. A telescopic scraper 210 is fixedly installed on the bottom outer side of the fixed vertical plate 29. The bottom of the telescopic scraper 210 is attached to the bottom inner end of the sedimentation tank 2.

[0029] Furthermore, by simultaneously activating two sets of electric push rods 26, it is easy to push the connecting vertical plates 27 on both sides in opposite directions. When the connecting vertical plates 27 move, they drive the telescopic push frame 28 to move accordingly. At this time, the telescopic push frame 28 moves to adjust its own length. The two ends move in opposite directions at the same time, thereby driving the fixed vertical plate 29 to move accordingly. The fixed vertical plate 29 drives the telescopic support plate 21 and the telescopic scraper 210 to extend and retract simultaneously, changing their own length. This allows the width of the sedimentation tank 2 to be adjusted according to its width.

[0030] The working principle of the sludge scraping device used in the sedimentation tank of sewage treatment will be explained in detail below.

[0031] like Figure 1-5 As shown, during use, the sewage inside the sedimentation tank is discharged out through the outlet. At this time, the output end of the motor 212 drives the drive rod 213 to cause the rotating gear 214 to rotate at a constant speed. The rotating gear 214 causes the brake tooth plate 22 to gradually move to the other end of the sedimentation tank 2. The movement of the brake tooth plate 22 causes the telescopic scraper 210 to move accordingly. The telescopic scraper 210 scrapes the sludge settled at the bottom of the sedimentation tank 2, so that it can enter the sludge collection box 3 with the sludge outlet 215. The scraper assembly is lifted upward to facilitate separation from the sedimentation tank 2. The two sets of electric push rods 26 are started at the same time to push the connecting vertical plates 27 on both sides in opposite directions. When the connecting vertical plates 27 move, the telescopic push frame 28 moves accordingly. At this time, the telescopic push frame 28 moves to adjust its own length. The two ends move in opposite directions at the same time, which in turn drives the fixed vertical plate 29 to move accordingly. The fixed vertical plate 29 drives the telescopic support plate 21 and the telescopic scraper 210 to extend and retract at the same time, changing their own length. The width of the scraper can be adjusted according to the width of the sedimentation tank 2.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
