Description

Technical Field

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

[0002] China's per capita freshwater resources are among the lowest in the world, while water pollution from large industrial sites is becoming increasingly serious. As a result, wastewater treatment has attracted more and more attention. Existing wastewater treatment methods include physical sedimentation, chemical sedimentation, and biodegradation. However, regardless of the method used, a large amount of sludge will accumulate at the bottom of the wastewater treatment device after a period of time. In order to ensure the normal and effective operation of wastewater treatment, users often need to clean the sludge inside the wastewater treatment device.

[0003] According to a search, Chinese patent document, publication number CN208865245U, discloses a sludge removal device for sewage treatment. This device uses a scraper to avoid the need for drainage operations during sludge removal, saving time and ensuring uninterrupted sewage treatment, thus improving efficiency. It avoids the traditional manual cleaning method, reducing the user's workload and lowering costs. However, during use, intermittent water interruptions are required for sludge removal. Repeated start-stop cycles can damage the device and reduce processing efficiency. Furthermore, while a screw drive moves the scraper to remove sludge, sludge tends to adhere to the screw, damaging it and causing poor sludge removal, leading to jamming, complicated maintenance, and high costs. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a sludge removal device for wastewater treatment, which improves sludge removal efficiency and avoids the reduction of sludge removal effect and wastewater treatment efficiency due to intermittent start-stop. Furthermore, the device has the advantages of a stable overall structure, low maintenance cost, and good sludge removal effect, thus solving the aforementioned technical problems.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a sludge removal device for sewage treatment, comprising a sewage tank, wherein a first isolation frame and a second isolation frame are movably installed on the inner side of the sewage tank, and fixing plates are fixedly installed at both ends of the first isolation frame and the second isolation frame, and an electric push rod is provided between the second isolation frame and the sewage tank, a cylinder is provided on the rear side of the sewage tank, and a sludge scraper seat is fixedly installed on the driving end of the cylinder, an inlet pipe and an outlet pipe are provided on the rear and front sides of the sewage tank, respectively, and a top plate is installed on the top side of the sewage tank by bolts.

[0008] Preferably, the top side of the sewage tank has two cavities, and gears are movably installed on the inner side of the cavities via a rotating shaft. The inner side of the sewage tank has two sets of mating grooves, and the inner side of the sewage tank has two sets of sludge scraping frames fixedly installed. The sludge scraping frames have an inclined structure.

[0009] With the above technical solution, since gears are installed inside the cavity, the first isolation frame will move during the movement of the second isolation frame, which is conducive to power transmission. Furthermore, the sludge scraper frame is used to scrape off the sludge on the partition plate and prevent the sludge from entering the inner side of the mating groove and affecting the engagement effect of the first and second isolation frames.

[0010] Preferably, limit rods are fixedly installed at both ends of the first isolation frame, and limit sleeves are sleeved on the outer side of the limit rods. The limit sleeves are fixedly installed on the front and rear sides of the sewage tank, and a baffle is fixedly installed on the right end of the electric push rod. The baffle is fixedly installed on the outer side of the sewage tank.

[0011] Through the above technical solution, during the movement of the No. 1 isolation frame, the two sets of limiting rods move in the corresponding limiting sleeves, which helps to improve the stability of the No. 1 isolation frame during movement. Moreover, under the action of the baffle, it is convenient to start the electric push rod to push the No. 2 isolation frame to move back and forth.

[0012] Preferably, the second isolation frame includes a partition and a side plate, the size and shape of the partition are respectively matched with the fitting groove, and the side plate is fixedly installed on the left side of the partition. The size and shape of the second isolation frame are the same as those of the first isolation frame.

[0013] Through the above technical solution, under the action of the No. 2 isolation frame and the No. 1 isolation frame of the same specification, it is beneficial to use them alternately during the sludge discharge process, thereby achieving the isolation effect through the partition. Moreover, under the action of the side plate, it is convenient for the electric push rod to push the side plate to drive the No. 2 isolation frame to move.

[0014] Preferably, the fixing plates are arranged in pairs, with a total of two sets. Racks are fixedly installed on opposite sides of the fixing plates, and the opposite sides of the racks are connected to gears through meshing.

[0015] Through the above technical solution, during the movement of the No. 2 isolation frame, the fixed plate and the rack on the top side move, thereby driving the gear to rotate. This facilitates the rack on the No. 1 isolation frame to move in the opposite direction, allowing the No. 1 isolation frame to be pulled out of the sewage tank. This facilitates alternating isolation between the No. 1 and No. 2 isolation frames, avoiding water interruption operations that would affect sewage treatment efficiency and sludge removal effect.

[0016] Preferably, the sludge scraper seat has an L-shaped structure, and a guide rod is fixedly installed at each of the two ends of the rear side of the sludge scraper seat. The guide rod is movably installed inside the guide hole on the rear side of the sewage tank, and a sludge discharge trough is opened at the lower end of the front side of the sewage tank.

[0017] Through the above technical solution, during the sludge discharge process, the starting cylinder drives the sludge scraper seat to move and discharge the sludge from the sludge discharge trough. Under the action of the guide rod, it is beneficial to improve the stability of the sludge scraper seat during sludge discharge. The structure is simple, the sludge discharge effect and smoothness are high, the maintenance cost is reduced and the device is not affected by sludge.

[0018] Compared with the prior art, the present invention provides a sludge removal device for sewage treatment, which has the following beneficial effects:

[0019] 1. In this utility model, sewage is discharged into the sewage tank through the inlet pipe and then treated. After the sewage treatment is completed, it is discharged through the drain pipe. During the treatment process, sludge accumulates on the top side of the partition. When discharging sludge, the electric push rod is activated to push the No. 2 isolation frame to move into the sewage tank and engage with the matching groove. At this time, the movement of the No. 2 isolation frame drives the fixed plate and the rack on the top side to move, thereby driving the gear to rotate. This facilitates the rack on the No. 1 isolation frame to move in the opposite direction, so that the No. 1 isolation frame can be pulled out of the sewage tank. This allows for alternating isolation through the No. 1 and No. 2 isolation frames, avoiding water interruption operations that would affect sewage treatment efficiency and sludge discharge effect.

[0020] 2. When the No. 1 and No. 2 isolation frames are pulled out alternately, the sludge on the partition is scraped off by the sludge scraping frame, and the sludge is prevented from entering the inner side of the mating groove and affecting the locking effect of the No. 1 and No. 2 isolation frames. Then, the sludge scraping seat is moved by the starting cylinder and the sludge is discharged from the sludge discharge groove. The guide rod helps to improve the stability of the sludge scraping seat when discharging sludge. The structure is simple, the sludge discharge effect and smoothness are high, the maintenance cost is reduced and the device is not affected by sludge. Attached Figure Description

[0027] 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.

[0028] Example 1:

[0029] like Figure 1-5 As shown, the present invention provides a sludge removal device for sewage treatment, including a sewage tank 1. A first isolation frame 2 and a second isolation frame 3 are movably installed on the inner side of the sewage tank 1. Fixed plates 4 are fixedly installed at both ends of the first isolation frame 2 and the second isolation frame 3. An electric push rod 5 is provided between the second isolation frame 3 and the sewage tank 1. A cylinder 6 is provided on the rear side of the sewage tank 1. A sludge scraper seat 7 is fixedly installed on the driving end of the cylinder 6. A water inlet pipe 8 and a water outlet pipe 9 are provided on the rear and front sides of the sewage tank 1, respectively. A top plate 10 is installed on the top side of the sewage tank 1 by bolts.

[0030] Specifically, two cavities 101 are respectively opened on the top side of the sewage tank 1. Gears 102 are movably installed inside the cavities 101 via rotating shafts. Two sets of engagement grooves 103 are opened inside the sewage tank 1. Two sets of sludge scraper frames 104 are fixedly installed inside the sewage tank 1. The sludge scraper frames 104 have an inclined structure. The advantage is that the gears 102 set inside the cavities 101 facilitate the movement of the first isolation frame 2 during the movement of the second isolation frame 3, which is conducive to power transmission. Furthermore, the sludge scraper frames 104 are conducive to scraping off the sludge on the partition 301 and prevent sludge from entering the engagement grooves 103 and affecting the engagement effect of the first isolation frame 2 and the second isolation frame 3.

[0031] Specifically, limit rods 201 are fixedly installed at both ends of the first isolation frame 2. Limit sleeves 202 are fitted onto the outer sides of the limit rods 201. The limit sleeves 202 are fixedly installed on the front and rear sides of the sewage tank 1. A baffle 501 is fixedly installed on the right end of the electric push rod 5, and the baffle 501 is fixedly installed on the outer side of the sewage tank 1. The advantage is that by moving the two sets of limit rods 201 within the corresponding limit sleeves 202, the stability of the first isolation frame 2 during movement is improved. Furthermore, the baffle 501 facilitates the activation of the electric push rod 5 to push the second isolation frame 3 to reciprocate.

[0032] Specifically, the second isolation frame 3 includes a partition plate 301 and a side plate 302. The size and shape of the partition plate 301 are matched with the fitting groove 103, and the side plate 302 is fixedly installed on the left side of the partition plate 301. The size and shape of the second isolation frame 3 are the same as those of the first isolation frame 2. The advantage is that by using the second isolation frame 3 and the first isolation frame 2 of the same specifications, it is convenient to use them alternately during the sludge discharge process, thereby achieving the isolation effect through the partition plate 301. Moreover, under the action of the side plate 302, it is convenient for the electric push rod 5 to push the side plate 302 to move the second isolation frame 3.

[0033] Example 2:

[0034] like Figure 1-5 As shown, this is an improvement on the previous embodiment. Specifically, the fixing plates 4 are arranged in pairs, with a total of two sets. Racks 401 are fixedly installed on opposite sides of the fixing plates 4, and the opposite sides of the racks 401 are meshed with gears 102. The advantage is that when the second isolation frame 3 moves, it moves the fixing plates 4 and the racks 401 on the top side, thereby rotating the gears 102. This facilitates the reverse movement of the racks 401 on the first isolation frame 2, allowing the first isolation frame 2 to be pulled out of the sewage tank 1. This facilitates alternating isolation between the first isolation frame 2 and the second isolation frame 3, avoiding water interruption operations that could affect sewage treatment efficiency and sludge removal.

[0035] Specifically, the scraper seat 7 has an L-shaped structure, and a guide rod 701 is fixedly installed at each of the two ends of the rear side of the scraper seat 7. The guide rod 701 is movably installed inside the guide hole on the rear side of the sewage tank 1, and a sludge discharge trough is opened at the lower end of the front side of the sewage tank 1. The advantages are that the scraper seat 7 is moved by starting the cylinder 6, and the sludge is discharged from the sludge discharge trough. Under the action of the guide rod 701, the stability of the scraper seat 7 during sludge discharge is improved. The structure is simple, the sludge discharge effect and smoothness are high, the maintenance cost is reduced, and the device is not affected by sludge.

[0036] During use, wastewater is discharged into the wastewater tank 1 through the inlet pipe 8 and then treated. After treatment, the wastewater is discharged through the drain pipe 9. During the treatment process, sludge accumulates on the top side of the partition 301. When discharging sludge, the electric push rod 5 is activated to push the second partition 3 towards the inside of the wastewater tank 1 and engage with the fitting groove 103. At this time, the movement of the second partition 3 drives the fixed plate 4 and the rack 401 on the top side to move, thereby driving the gear 102 to rotate. This facilitates the reverse movement of the rack 401 on the first partition 2, allowing the first partition 2 to be pulled out of the wastewater tank 1, making it easier to pass through the first partition 2 and the second partition. The isolation frame 3 is used for alternating isolation to avoid water interruption operations, which would affect the sewage treatment efficiency and sludge discharge effect. When the first isolation frame 2 and the second isolation frame 3 are pulled out alternately, the sludge on the partition plate 301 is scraped off by the sludge scraper frame 104, and the sludge is prevented from entering the inner side of the fitting groove 103 and affecting the locking effect of the first isolation frame 2 and the second isolation frame 3. Then, the sludge scraper seat 7 is moved by the starting cylinder 6 and the sludge is discharged from the sludge discharge groove. The guide rod 701 helps to improve the stability of the sludge scraper seat 7 when discharging sludge. The structure is simple, the sludge discharge effect and smoothness are high, the maintenance cost is reduced and the device is not affected by sludge.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
