Abstract
Description
Technical Field
[0001] This utility model relates to the field of conveyor technology, specifically to a sludge treatment conveyor with a scraping mechanism. Background Technology
[0002] In municipal wastewater treatment, industrial wastewater treatment, and solid waste treatment processes, sludge conveying is a crucial link connecting the sludge source with the treatment equipment. Because sludge contains large amounts of water, microorganisms, organic matter, and impurities such as sand and gravel, it exhibits high viscosity, a tendency to caking, and strong corrosiveness, posing numerous challenges to traditional conveying equipment in its application.
[0003] Currently, in existing technologies, traditional conveyors mostly use rigid scrapers with fixed angles, such as integrated straight scrapers or simple hinged scrapers. When dealing with sludge with different characteristics, it is difficult to flexibly adjust the scraping height. When processing high-viscosity or caking sludge, the scraper resistance is too high, making it difficult to scrape the material and resulting in a large amount of sludge residue. Therefore, a conveyor for sludge treatment with a scraping mechanism is proposed. Utility Model Content
[0004] The main objective of this invention is to provide a sludge treatment conveyor with a scraping mechanism, which can solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides a sludge treatment conveyor with a scraping mechanism, comprising a support frame, a support plate fixedly connected to the top of the support frame, a connecting frame fixedly connected to the top of the support plate, a conveying assembly for sludge transport on the left side of the support frame, and a scraping assembly for sludge scraping on the top of the connecting frame. The conveying assembly includes:
[0006] Mounting bracket, which is fixedly connected to the left side of the support frame;
[0007] An electric motor, which is mounted on top of a mounting bracket;

[0010] A transmission roller is fixedly connected to the outer wall of the end of the rotating shaft away from the motor.
[0011] A conveyor belt, which is fitted onto the outer wall of the conveyor roller.
[0012] Preferably, the main drive wheel is connected to a secondary drive wheel via a drive belt, a rotating rod is fixedly connected to the inner wall of the secondary drive wheel, a sprocket is fixedly connected to the outer wall of the rotating rod, and a chain is engaged with the sprocket.
[0013] Preferably, a bearing seat is fixedly connected to the top of the connecting frame, and the rotating rod is rotatably connected to the bearing seat through a bearing.
[0014] Preferably, the scraping assembly includes a fixing plate, which is fixedly connected to the bottom of the chain. A threaded rod is rotatably connected to the bottom of the fixing plate via a bearing. A frame is threadedly connected to the outer wall of the threaded rod. A scraper blade is fixedly connected to the bottom of the frame. A scraper blade is hinged to the left side of the scraper blade. The sludge on the conveyor belt can be scraped off by the scraper blade and the scraper blade.
[0015] Preferably, a groove is provided on the left side of the scraper second, and a slider is slidably connected in the groove. The right side of the slider is elastically connected to the scraper first through a spring, and the spring can automatically adjust the angle of the scraper second according to the resistance.

[0017] Preferably, a secondary scraper is fixedly connected to the top of the chain, which can perform secondary scraping of any missed or incompletely scraped sludge.
[0018] This utility model provides a sludge treatment conveyor with a scraping mechanism. It has the following beneficial effects:
[0019] (1) The sludge treatment conveyor with scraping mechanism is connected by a hinged elastic connection between scraper one and scraper two. The scraper can automatically adjust the scraping angle according to the sludge resistance. When encountering high viscosity or caking sludge, the sludge reaction force pushes scraper two to compress the spring, causing it to rotate around the hinge point to reduce the opening angle and reduce the insertion resistance. When processing soft sludge, the spring resets and the scraper pushes quickly at a large angle to achieve the effect of removing residual sludge from the surface of the conveyor belt.
[0020] (2) The sludge treatment conveyor with scraping mechanism scrapes the sludge by cooperating with the transfer component and the scraping component. The threaded rod manual adjustment mechanism of the scraper component and the angle fine adjustment design of the auxiliary scraper support quick adaptation to different working conditions and scraping sludge of different thicknesses.

The conveying assembly 4 includes a mounting frame 41, a motor 42, a rotating shaft 43, a main drive wheel 44, a conveying roller 45, and a conveyor belt 46. The mounting frame 41 is fixedly connected to the left side of the support frame 1, the motor 42 is mounted on the top of the mounting frame 41, the rotating shaft 43 is connected to the output shaft of the motor 42, the main drive wheel 44 is fixedly connected to the outer wall of the rotating shaft 43, the conveying roller 45 is fixedly connected to the outer wall of the rotating shaft 43 away from the motor 42, and the conveyor belt 46 is sleeved on the outer wall of the conveying roller 45.
[0031] In an embodiment of this utility model, in order to scrape the sludge, specifically, the main drive wheel 44 is connected to the auxiliary drive wheel 5 via a drive belt. The inner wall of the auxiliary drive wheel 5 is fixedly connected to a rotating rod 6, and the outer wall of the rotating rod 6 is fixedly connected to a sprocket 61. The sprocket 61 is meshed with a chain 62. The scraping assembly 7 includes a fixing plate 71, which is fixedly connected to the bottom of the chain 62. The bottom of the fixing plate 71 is rotatably connected to a threaded rod 72 via a bearing. The outer wall of the threaded rod 72 is threadedly connected to a frame 73. The bottom of the frame 73 is fixedly connected to a scraper 1 74, and a scraper 2 75 is hinged to the left side of the scraper 1 74. The sludge on the conveyor belt 46 can be scraped off by the scraper 1 74 and the scraper 2 75.
[0032] Furthermore, a groove 76 is provided on the left side of scraper 2 75, and a slider 77 is slidably connected in the groove 76. There are two sets of groove 76 and slider 77, which are symmetrically arranged in the middle of fixed plate 71. The right side of slider 77 is elastically connected to scraper 1 74 by spring. The spring can automatically adjust the angle of scraper 2 75 according to the resistance. The two sides of fixed plate 71 are movably connected to the top of connecting frame 3 by pulleys. Threaded rod 72 moves through fixed plate 71 and extends upward. The extended end of threaded rod 72 is provided with a rotating handle.
[0033] Furthermore, a bearing seat 63 is fixedly connected to the top of the connecting frame 3, and the rotating rod 6 is rotatably connected to the bearing seat 63 through the bearing. A secondary scraper 8 is fixedly connected to the top of the chain 62. There are two secondary scrapers 8, which are located at both ends of the chain 62 respectively, and can perform secondary scraping of missed or incompletely scraped sludge.
[0034] It should be noted that the above electrical components are all existing technology products. Those skilled in the art should select, install, and complete the circuit debugging work according to the needs of use to ensure that all electrical appliances can work normally. For example, the motor 42 is connected to the mains power. The components are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are made here.
[0035] In this invention, during use, sludge is evenly spread on the surface of the conveyor belt 46 from the right side of the equipment. When the motor 42 is powered on, the output shaft drives the rotating shaft 43 to rotate. The rotating shaft 43 synchronously drives the main drive wheel 44 and the conveyor roller 45 to rotate. The conveyor belt 46 is driven by the conveyor roller 45 to transport the sludge. The main drive wheel 44 transmits power to the auxiliary drive wheel 5 through the synchronous belt, causing the rotating rod 6 to rotate. The rotating rod 6 drives the sprocket 61 on the outer wall to rotate with the rotating rod 6. The chain 62 engaged by the sprocket 61 forms a cyclic transmission, driving the scraper assembly 7 fixed at the bottom of the chain 62 to reciprocate along the top track of the connecting frame 3 to scrape the sludge. When encountering clumped sludge, the reaction force of the sludge pushes the scraper 75 to rotate counterclockwise around the hinge point. The slider 77 slides in the groove 76 and compresses the spring. The opening angle of the scraper... The frame is narrowed to reduce frontal resistance. After the scraper passes through the sludge, the spring force pushes scraper 75 back to its original position, restoring the large-angle scraping state and ensuring conveying efficiency. The operator can manually adjust the height of frame 73 by rotating the handle at the top of threaded rod 72. Rotating clockwise makes scraper 74 close to conveyor belt 46 to scrape off a thin layer of sludge. Rotating counterclockwise raises frame 73, leaving a larger gap to avoid hard contact between scraper 74 and scraper 75 and conveyor belt, which is suitable for conveying sludge containing large impurities.

Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
