Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, in particular to an integral lifting non-clogging disc aeration device. Background Art

[0002] The aerator is the main equipment of the aeration device. It plays an important role in oxygen supply, mass transfer, stirring and mixing in the water treatment process. Its oxygen supply efficiency, installation method, maintenance conditions, etc. are directly related to the treatment effect and operating cost of the entire water treatment system. After decades of development and research, high-efficiency aerators such as ceramic micropores and rubber membrane micropores have been developed. The traditional method uses a fixed installation at the bottom of the underwater pool, which is extremely inconvenient to repair. Especially when encountering a large sewage treatment plant, it is necessary to drain the water first and then enter the pool bottom for maintenance, which consumes a lot of manpower and material resources and also affects the water treatment efficiency; some of the existing technologies directly use a hoist to hoist the aerator equipment, usually using a motor reel or a telescopic hydraulic cylinder as a power equipment to realize the lifting of the aerator, wherein the aerator equipment is raised to the upper end of the aeration tank, and during the inspection and maintenance process, in order to ensure the stability of the aerator, the power equipment such as the motor needs to be in working condition for a long time.

[0003] In order to solve the problem that the current lifting aeration device causes loss to electrical equipment and consumes electric energy during operation, the prior art proposes a lifting aeration device that is easy to adjust for a sewage treatment aeration tank, as recorded in patent CN212102219U, both ends of the aeration tank body are slidably connected with fixed seats, the aerator body is fixedly installed between the fixed seats by bolts, a hanging ring is fixedly connected to the top of the fixed seat, a steel cable is fixedly connected to the hanging ring, a positioning column is threadedly connected to the inner wall of the upper end of the fixed seat, a first support plate is fixedly connected to the upper end of the aeration tank body, a winding disk is connected between the first support plates through a bearing, one end of the winding disk is fixedly connected to the output end of the motor, the steel cable is wound on the winding disk, support seats are fixedly connected to the two side walls of the aeration tank body, and a guide rod is slidably inserted into the interior of the support seat, One end of the guide rod passes through the inner side of the support seat and is fixedly connected with a positioning plate, and a positioning block is fixedly connected to the bottom side wall of the positioning plate, and the positioning block plug-in is fixedly connected to the positioning column, and the guide block is fixedly connected to the outer wall of the fixing seat, a guide groove is provided on the inner wall of the aeration tank body, and the guide groove is matched and connected with the guide block, and a second support plate is fixedly connected to the inner wall of the upper end of the aeration tank body, and a guide wheel is connected between the second support plates through a bearing, and the guide wheel is slidably connected to the steel cable rope, and a rubber sleeve is slidably sleeved on the lower end of the steel cable rope, and a sliding groove matched with the steel cable rope is provided inside the rubber sleeve, and a positioning groove matched with the positioning column is provided inside the positioning block, and an anti-slip rubber pad is fixedly connected to the groove wall of the positioning groove, and a baffle is fixedly connected to the other end of the guide rod, and the baffle and the support seat are fixedly connected by a spring;

[0004] However, when the utility model is in operation, sludge will inevitably fall during the lifting process of the aeration tank, and sludge is often easily accumulated in the guide groove. Long-term accumulation will affect its lifting system and is difficult to clean. Since the aeration tank is large in size, only using guide rods to position it has low strength and insufficient stability.

[0005] Therefore, there is an urgent need for an overall lifting non-clogging disc aeration device that can prevent the accumulation of sludge in the limiting groove from affecting the lifting of the disc aeration tank body, limit the hanging rope, and reinforce and improve the stability of the positioning of the disc aeration tank after lifting. Utility Model Content

[0006] Based on the above technical problems, the utility model provides an integrally lifting non-clogging disc aeration device, which achieves the function of preventing the accumulation of sludge in the limiting groove from affecting the lifting of the disc aeration tank body, limiting the hanging rope, and reinforcing and improving the stability of the positioning of the disc aeration tank after lifting.

[0007] The utility model is characterized in that it comprises an external frame structure, a lifting structure and a locking structure. The lifting structure is installed on the upper end of the external frame structure, and the locking structure is installed inside the external frame structure.

[0008] The outer frame structure consists of an outer wall and a lifting pool. The lifting pool is installed on the inner side of the outer wall, and limiting grooves are arranged on both sides of the lifting pool.

[0009] The lifting structure consists of a disc aeration tank body, a scraper disc, an L-shaped hook, a limit block, and an L-shaped clamping block. Limit blocks are installed on both sides of the disc aeration tank body. A scraper disc is installed at the lower end of the disc aeration tank body. The scraper disc is provided with through holes, and the number of through holes is multiple. An L-shaped clamping block is installed at the upper end of the disc aeration tank body, and an L-shaped hook is installed in the middle of the L-shaped clamping block.

[0010] The locking plate is rotatably connected to the L-shaped locking plate, and the locking plate is provided with a Y-shaped locking plate on both sides of the screw. A fixed pulley is installed on one side of the Y-shaped limiting plate, and the upper end of the mounting block is fixedly connected to the lifting motor, and a hanging rope is installed on the lifting motor, and the hanging rope is connected to the L-shaped hanging buckle through the fixed pulley.

[0011] The beneficial effects of the utility model are:

[0012] The utility model adds a sleeve, a Y-shaped limit plate, a limit column, a limit end, an adjustment disk, and a mud scraper disk on the original basis, improves the L-shaped hanging buckle and the L-shaped clamping block, and opens a through hole on the mud scraper disk, so as to avoid the influence of sludge accumulation in the limit groove on the lifting of the disc aeration tank, limit the hanging rope, and reinforce and improve the positioning stability of the disc aeration tank after lifting.

[0013] The sleeve and the adjusting disk make it more convenient to control the positioning of the disc aeration tank after it is lifted, making it easier for operators to understand and operate.

[0014] The limit end ensures that the rotation of the screw does not affect the positioning plate, thus preventing the screw from getting stuck.

[0015] The scraper plate and through holes can scrape away the accumulated sludge in the limit groove to prevent its accumulation from affecting the movement of the limit block and further affecting the lifting of the disc aeration tank. Through holes are opened on the scraper plate to avoid the situation where the scraper plate is difficult to separate due to the large contact area between the scraper plate and the lifting groove ground.

[0016] The Y-shaped limit plate limits the hanging rope to prevent the hanging rope from tilting or even falling off the pulley during the lifting of the disc aeration tank.

[0017] The limiting column improves the strength of the positioning plate without affecting the movement of the positioning plate, making the positioning of the disc aeration tank after lifting more stable and reliable. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Example 1

[0024] The utility model provides an integral lifting non-clogging disc aeration device, which comprises an outer frame structure, a lifting structure and a clamping structure.

[0025] A lifting pool 12 is installed on the inner side of the outer wall 11 , and limiting grooves 13 are provided on both sides of the lifting pool 12 .

[0026] Limiting blocks 25 are installed on both sides of the disc aeration tank body 21, a scraper disc 22 is installed at the lower end of the disc aeration tank body 21, and a through hole 23 is opened on the scraper disc 22. There are multiple through holes 23. An L-shaped block 26 is installed at the upper end of the disc aeration tank body 21, and an L-shaped hook 24 is installed in the middle of the L-shaped block 26.

[0027] A sleeve 32 is connected through the middle of the mounting block 31, and the sleeve 32 can rotate around the axis in the mounting block 31. An adjusting disk 311 is installed at the closed end of the sleeve 32. The inside of the sleeve 32 is threadedly connected to the screw 37. A limited position end 30 is welded on the side of the screw 37 away from the mounting block 31. A clamping plate 38 is rotatably connected to the outer side of the limited position end 30. The clamping plate 38 is installed with limited position columns 39 on both sides of the screw 37. There are multiple limited position columns 39. The limited position columns 39 pass through the mounting block 31 and are slidably connected to the mounting block 31. A Y-shaped limiting plate 34 is fixedly connected to the upper end of the mounting block 31, and a fixed pulley 35 is installed on one side of the Y-shaped limiting plate 34. A lifting motor 33 is fixedly connected to the upper end of the mounting block 31. A hanging rope 36 is installed on the lifting motor 33, and the hanging rope 36 is connected to the L-shaped hanging buckle 24 through the fixed pulley 35.

[0028] Example 2

[0029] When the operator needs to lift the disc aeration tank body 21, the lifting motor 33 is turned on to retract the hanging rope 36 to lift the disc aeration tank body 21. After the hanging rope 36 is limited by the Y-shaped limiting plate 34, the fixed pulley 35 applies a pulling force to the L-shaped hanging buckle 24 connected thereto, driving the disc aeration tank body 21 to move upward along the limiting groove 13 through the limiting block 25. During the upward movement, the scraper disc 22 scrapes away the sludge accumulated in the limiting groove 13.

[0030] When the disc aeration tank body 21 is lifted to the top height, the operator rotates the adjustment disk 311 to rotate the sleeve 32 on the mounting block 31, pushing the screw 37 out, and the screw 37 pushes the locking plate 38 out through the limiting end 30, and the limiting column 39 follows the locking plate 38 to slide out of the mounting block 31. The locking plate 38 is adjusted to the locking part of the L-shaped hook 24 and the L-shaped block 26 to achieve positioning of the disc aeration tank body 21.

[0031] When the disc aeration tank body 21 needs to be lowered back to its original position, the adjusting disk 311 is adjusted so that the sleeve rotates in the mounting block 31 and the screw 37 is retracted. The screw 37 retracts the positioning plate 38 through the inner end 30, and the limiting column 39 slides through the mounting block 31, and finally the L-shaped hook 24 and the L-shaped block 26 are released. The lifting motor 33 is reversed, and the disc aeration tank body 21 is lowered back to the bottom of the lifting tank 12 along the limiting groove 13 through the hanging rope 36.
