Description

Technical Field

[0001] This utility model belongs to the technical field of sludge scrapers, specifically relating to an underwater non-metallic chain sludge scraper. Background Technology

[0002] The underwater non-metallic rotary sludge scraper is a high-efficiency sludge removal device for sedimentation tanks, specifically designed for wastewater treatment. Its core is made of corrosion-resistant scraper blades, which are directly driven by a motor to the central drive shaft, causing the radial scraper blades to rotate slowly and continuously scrape out the settled sludge from the bottom of the tank.

[0003] Traditional sludge scrapers typically use flat scrapers that adhere to the sludge in a planar manner. During the scraping process, this structure relies solely on the pushing force of the scraper to move surface sludge. For sludge adhering to the bottom of the tank, the limited contact area and insufficient friction make it difficult to completely remove it, resulting in sludge residue at the bottom. Especially when processing highly viscous sludge, the flat scraper easily slips across the surface, failing to penetrate deep into the sludge for effective removal. Utility Model Content

[0004] The purpose of this invention is to provide an underwater non-metallic chain-type sludge scraper to solve the problem in the background art where traditional sludge scrapers mostly use flat scrapers, which are in flat contact with the sludge. During the scraping process, this structure can only rely on the pushing force of the scraper to scrape the surface sludge. For sludge attached to the bottom of the tank, due to the limited contact area and insufficient friction, it is difficult to completely scrape it off, resulting in sludge residue at the bottom of the tank. Especially when dealing with some highly viscous sludge, the flat scraper easily slides over the sludge surface and cannot penetrate deep into the sludge for effective scraping.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an underwater non-metallic chain scraper, comprising a traveling frame and a control motor disposed in the middle of the upper side of the traveling frame;

[0006] The lower end of the control motor is connected to a transmission platform, and a transmission shaft is provided on the lower middle side of the transmission platform. Three fixing plates are provided at equal intervals on the lower end of the transmission shaft.

[0007] The control motor and the transmission table are powered by connecting to an external power source.

[0008] A connecting rod is provided on the upper side of the end of each of the three fixed plates, and three rotating rings are provided at equal intervals on the upper outer side of the connecting rod;

[0009] A scraper is provided on the inner middle side of the fixed plate, a serrated plate is provided on the front side of the fixed plate, and side plates are provided at the front and rear ends of the rear side of the fixed plate, with a roller provided on the inner middle side of the two side plates.

[0010] Preferably, multiple fixing bolts are provided at the connection position between the sawtooth plate and the fixing plate, and multiple sawtooth grooves are opened at the lower end of the sawtooth plate.

[0011] Preferably, the scraper blade is connected to the fixing plate via an insert connection, and a retaining plate and bolts are provided at one end of the scraper blade to fix it to the fixing plate.

[0012] Preferably, the two side plates are connected to the fixed plate by welding, and the roller is connected to the two side plates by a movable connection.

[0013] Preferably, the scraper is inclined, and the lowest point of the lower side of the scraper is lower than the lowest point of the roller and the toothed plate.

[0014] Preferably, the three fixing plates are connected by welding and transmission shafts respectively, and a transmission reducer and a transmission motor are provided on the inner side of the transmission table.

[0015] Preferably, the three connecting rods are connected by welding, three rotating rings, and three fixing plates, respectively, and the lower sides of the left and right ends of the walking frame are fixed to the external ground by bolts.

[0016] Compared with the prior art, this utility model provides an underwater non-metallic chain-type sludge scraper, which has the following beneficial effects:

[0017] 1. The multiple serrated grooves at the lower end of the serrated plate increase the contact area and friction with the sludge. During the sludge scraping process, the serrations can embed deeper into the sludge, scraping it more thoroughly and improving scraping efficiency. The effect of the serrations is particularly noticeable for sludge that is attached to the bottom of the pool or is difficult to scrape off.

[0018] Furthermore, when the sludge scraper is working, the toothed blades rotate with the fixed plate, and the teeth can break up the clumps in the sludge. This helps prevent the sludge clumps from becoming too large, which would affect the scraping effect and subsequent processing, allowing the sludge to be scraped and transported more evenly.

[0019] In addition, the presence of serrations disrupts the structure of the sludge, making it easier for the sludge to flow when scraped. This facilitates the smooth movement of the sludge in the designated direction under the action of the scraper, reducing the accumulation and retention of sludge at the bottom of the tank.

[0020] 2. The rollers are located between the two side plates behind the fixed plate and work in conjunction with the scraper. During the scraping process, the rollers roll, further pushing the sludge scraped by the scraper, thus assisting in the conveying process. This allows the sludge to be collected and transferred more smoothly, improving the overall efficiency of the scraper. Furthermore, the rolling motion of the rollers reduces the frictional resistance between the scraper and the sludge and the tank bottom during operation. Compared to directly dragging the scraper, the rolling friction of the rollers is lower, which not only reduces energy consumption but also reduces wear on the scraper and the tank bottom, extending the equipment's service life.

[0021] 3. The rollers can adapt to uneven terrain at the bottom of the pool to a certain extent. When the sludge scraper encounters bumps or depressions at the bottom of the pool, the rollers can adjust their position by rolling, ensuring that the scraper blades always maintain good contact with the bottom of the pool, and ensuring that the sludge scraping effect is not affected by the terrain.

[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] This utility model provides, for example Figure 1-4The underwater non-metallic chain-type sludge scraper shown includes a traveling frame 1 and a control motor 3 located on the upper middle of the traveling frame 1. The lower sides of the left and right ends of the traveling frame 1 are fixed to the external ground by bolt connections. The traveling frame 1 is made of high-strength non-metallic composite material and is machined to the designed dimensions to ensure its structural strength and corrosion resistance. Bolt mounting holes are reserved on the lower sides of the left and right ends of the traveling frame 1 for fixed connection to the external ground.

[0029] The lower end of the control motor 3 is connected to the transmission platform 2, the lower middle side of the transmission platform 2 is provided with the transmission shaft 5, and the lower end of the transmission shaft 5 is provided with three fixed plates 7 at equal intervals.

[0030] The control motor 3 and the transmission table 2 are powered by connecting to an external power source.

[0031] Connecting rods 6 are provided on the upper side of the ends of the three fixed plates 7. Three rotating rings 4 are equidistantly arranged on the upper outer side of the connecting rods 6. The three connecting rods 6 are connected to the three rotating rings 4 and the three fixed plates 7 by welding.

[0032] Optionally, the user can fix the control motor 3 to the upper middle position of the walking frame 1, ensuring a secure installation. The lower end of the control motor 3 is connected to the transmission platform 2. A transmission reducer and a transmission motor are installed inside the transmission platform 2 to adjust and transmit power. The transmission shaft 5 is installed on the lower middle side of the transmission platform 2, allowing the transmission shaft 5 to rotate under the drive of the transmission platform 2.

[0033] In this embodiment, the user can move the walking frame 1 to a suitable position according to the actual size of the sedimentation tank and the sludge scraping requirements, and use bolts to fix the lower sides of the left and right ends of the walking frame 1 to the external ground to ensure that the equipment is installed stably.

[0034] Then, turn on the power switches of the control motor 3 and the transmission platform 2. After the control motor 3 starts, it transmits power to the transmission shaft 5 through the transmission reducer and transmission motor inside the transmission platform 2. The transmission shaft 5 starts to rotate, driving the three fixed plates 7 to perform circular motion.

[0035] As the fixed plate 7 rotates, the serrated plate 8 first contacts the sludge at the bottom of the sedimentation tank. The serrated grooves on the serrated plate 8 break up the sludge clumps, making the sludge easier to scrape. Subsequently, the inclined scraper plate 11 scrapes the broken sludge to one side. During the scraping process, the scraper plate 11 uses its tilt angle and movement trajectory to push the sludge and move it towards the sludge collection area. Finally, the roller 10 assists in pushing and compacting the scraped sludge, preventing the sludge from accumulating behind the scraper plate 11. At the same time, the rotation of the roller 10 further agitates the sludge, making the sludge more uniform during movement and improving the scraping efficiency.

[0036] During equipment operation, operators can observe the equipment's operating status and the sludge scraping in the sedimentation tank, and adjust the speed of the control motor 3 according to actual needs, thereby regulating the rotation speed of the fixed plate 7 and the scraping speed of the scraper 11. If wear or damage is found in the serrated plate 8, scraper 11, or roller 10, the machine can be stopped immediately for replacement and repair.

[0037] like Figure 1-4 As shown, a scraper 11 is provided on the inner side of the middle of the fixed plate 7, a serrated plate 8 is provided on the front side of the fixed plate 7, and side plates 12 are provided at the front and rear ends of the rear side of the fixed plate 7. A roller 10 is provided on the inner side of the middle of the two side plates 12. Multiple fixing bolts 9 are provided at the connection position between the serrated plate 8 and the fixed plate 7. Multiple serrated grooves are opened at the lower end of the serrated plate 8. The scraper 11 is connected to the fixed plate 7 in the middle by an insert connection. A clamping plate and bolt are provided at one end of the scraper 11 to fix it to the fixed plate 7. The two side plates 12 are connected to the fixed plate 7 by welding. The roller 10 is connected to the two side plates 12 by a movable connection. The scraper 11 is inclined. The lowest point of the scraper 11 is lower than the lowest point of the roller 10 and the serrated plate 8. The three fixed plates 7 are connected to the transmission shaft 5 by welding. A transmission reducer and a transmission motor are provided on the inner side of the transmission table 2.

[0038] Preferably, in this device, the serrated plate 8 can break up sludge clumps, making large clumps of sludge that were originally difficult to scrape loose and easier to be pushed by the scraper plate 11. The inclined design of the scraper plate 11 and the auxiliary pushing action of the roller 10 can effectively scrape the sludge to the designated area and reduce the amount of sludge residue at the bottom of the sedimentation tank.

[0039] In addition, the rotation of the roller 10 agitates and compacts the sludge, making the sludge more uniform during movement. This avoids the accumulation or uneven thickness of the sludge during the scraping process, ensuring that the sludge at the bottom of the sedimentation tank can be removed evenly and improving the consistency of the scraping effect.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
