Description

Technical Field

[0001] The utility model relates to the technical field of scraper components, in particular to a scraper for a chain-type scraper. Background Art

[0002] A scraper is a sewage auxiliary treatment equipment used in urban sewage treatment plants, water plants and industrial wastewater treatment. It can remove sludge settled at the bottom of the sedimentation tank and skim off scum on the surface of the tank. It is widely used. Chain scraper is one of the commonly used scrapers. The chain structure drives the scraper to circulate.

[0003] The existing chain scraper blades have the following disadvantages when in use: the existing chain scraper blades are usually ordinary one-piece plate structures. In order to simultaneously scrape off the sludge on the bottom of the pool and the scum on the pool surface, the scraper structure is usually longer in the vertical direction. When scraping off the sludge on the bottom of the sedimentation tank, the scraper continuously circulates, so the amount of sludge scraped each time is not large. The excessively long scraper height will increase its resistance to movement in the water, thereby increasing the load on the transmission component. For this reason, we propose a scraper for a chain scraper. Utility Model Content

[0004] The main purpose of the utility model is to provide a scraper for a chain-type mud scraper. By improving the scraper structure, the resistance of the scraper during underwater movement can be reduced, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A scraper for a chain-type scraper includes a scraper body and an adjustment mechanism. The adjustment mechanism is provided on the surface of the scraper body. The adjustment mechanism includes a through hole, a fixing frame, a slide groove, a slide rod, a floating seat, a fixed plate and a baffle. Through holes are equidistantly provided inside the scraper body. The scraper is fixedly connected to a fixing frame located on the outer periphery of the through hole and slide grooves are provided on both sides of the inner wall of the fixing frame. Slide rods are inserted into the through holes and a floating seat is provided between the ends of the slide rods. A fixed plate is fixedly connected between the slide rods near one end of the floating seat.

[0007] Furthermore, it also includes an auxiliary mechanism, the scraper main body surface is detachably connected to the auxiliary mechanism, the auxiliary mechanism includes a wear-resistant plate, a bottom plate, a clamping plate and a spring, the scraper main body surface is detachably connected to the wear-resistant plate and the ends of the wear-resistant plates are integrally formed with the bottom plate, the wear-resistant plate surface is integrally formed with a clamping plate clamped to the scraper main body surface and a spring is installed between the clamping plate and the bottom plate; the scraper main body surface and the wear-resistant plate installation corresponding position are provided with a tooth groove A structure, the clamping plate can be bent to a certain extent on the wear-resistant plate surface, and when the wear-resistant plate is installed, it is pressed toward one side of the bottom plate. The clamping plate compresses the spring to increase the distance between the clamping plate and the installation surface of the wear-resistant plate, and then align the wear-resistant plate with the installation position on the surface of the scraper body and insert it. After inserting it into place, release the clamping plate, and the clamping plate will automatically reset and clamp it to the surface of the scraper body, and cooperate with the end of the wear-resistant plate to fix the wear-resistant plate. At the same time, during the movement, the spring maintains the pressure of the clamping plate to one side of the scraper body, thereby maintaining the stability of the wear-resistant plate and preventing it from falling off. When the scraper is running, the wear-resistant plate on the outbound journey runs on the wear-resistant strip at the bottom of the scraper, and the wear-resistant plate on the return journey runs on the wear-resistant strip of the return guide rail, thereby improving the smoothness of equipment operation.

[0008] Furthermore, pulleys are installed on both sides of the surface of the slide rod and are attached to the inner wall of the slide groove; the pulley structure prevents the slide rod from directly contacting the inner wall of the slide groove, so that the slide rod can move smoothly under the drive of the floating plate.

[0009] Furthermore, a baffle corresponding to the through-hole position is bonded to the side of the fixed plate surface facing the scraper body; during the return movement, the baffle on the fixed plate surface just blocks the through-hole position, without affecting the scraping effect of the scum on the pool surface.

[0010] Furthermore, the scraper body surface and the wear-resistant plate installation corresponding position are provided with tooth grooves A, and the clamping plate surface is provided with tooth grooves B matching the tooth grooves A; when the wear-resistant plate is installed in place, the tooth grooves A and the tooth grooves B are exactly engaged with each other, thereby improving the installation stability of the wear-resistant plate.

[0011] Compared with the prior art, the utility model has the following beneficial effects: a through-hole structure is provided on the surface of the scraper body, and a floating seat and a baffle structure with movable position adjustment are installed on one side near the through-hole through a fixing frame. The scraper body is installed on the scraper chain and circulates with the chain. When the scraper body moves with the chain to the bottom of the pool to scrape the sludge at the bottom of the pool, the buoyancy of the water body causes the floating seat to float up, and the slide bar moves up along the slide slot while driving the baffle to be misaligned with the through-hole. At this time, water flow can pass through the through-hole during the movement of the scraper body, reducing the movement resistance of the scraper body and reducing the load of the transmission equipment. The sludge mainly accumulates at the bottom of the scraper body and does not affect the scraping effect. A small amount of sludge passing through the through-hole will also be scraped off by the subsequent scraper body. When the scraper body moves with the chain to the water surface position, the scraper body completes the flip. At this time, the buoyancy of the water body lifts the floating seat upward, which will cause the slide bar to drive the scraper to move up while the baffle It fits to one side of the through-hole position to complete the closure of the through-hole, thereby not affecting the scraper body's scraping effect on the water surface scum; a tooth groove A structure is provided on the surface of the scraper body and the corresponding position of the wear-resistant plate installation, and the splint can be bent to a certain extent on the surface of the wear-resistant plate. When installing the wear-resistant plate, press the splint toward one side of the bottom plate to compress the spring, increase the distance between the splint and the wear-resistant plate installation surface, and then align the wear-resistant plate to the installation position on the scraper body surface and insert it. After inserting it into place, release the splint, and the splint can automatically reset and clamp it to the surface of the scraper body, and cooperate with the end of the wear-resistant plate to fix the wear-resistant plate. At the same time, during the movement, the spring maintains the pressure of the splint to the side of the scraper body, thereby maintaining the stability of the wear-resistant plate and preventing it from falling off. The wear-resistant plate of the scraper runs on the wear-resistant strip at the bottom of the scraper during the outward operation, and the wear-resistant plate runs on the wear-resistant strip of the return guide rail during the return operation, thereby improving the smoothness of equipment operation.

Then the wear-resistant plate 302 is aligned with the mounting position on the surface of the scraper body 1 and inserted. After being inserted into place, the clamping plate 304 is released, and the clamping plate 304 can automatically reset and clamp to the surface of the scraper body 1, and cooperate with the end of the wear-resistant plate 302 to fix the wear-resistant plate 302. At the same time, during the movement, the spring 305 maintains the pressure of the clamping plate 304 toward the side of the scraper body 1, thereby maintaining the stability of the wear-resistant plate 302 and preventing it from falling off.
