Description

Technical Field

[0001] The utility model belongs to the technical field of water aeration devices and relates to an anti-winding device, in particular to an anti-winding device for an aerator. Background Art

[0002] The hanging chain aerator will swing during the aeration operation. When the aeration pressure is high, the aerator will malfunction due to the large swing amplitude and the pipes will be entangled with each other. In order to reduce the failure rate of the hanging chain aerator, the prior art often sets an external counterweight between two adjacent aerators, and uses the external counterweight to connect the two adjacent aerators into one, so as to avoid entanglement. Although this anti-entanglement method has a certain anti-entanglement effect, when the aerator needs to be cleaned and maintained as a whole, it is necessary to lift up the external counterweights one by one before the aerators can be lifted out of the pool one by one. This results in a huge workload for removing the external counterweights, which reduces the cleaning and maintenance efficiency and affects the water treatment progress of the water treatment pool. Therefore, it is necessary to provide a device that can easily and quickly lift the anti-entanglement counterweight when cleaning the aerators along the entire line. Utility Model Content

[0003] The utility model aims to provide an aerator anti-winding device to solve the technical problem in the prior art that the cleaning efficiency of the aerator system is low due to the huge workload of removing the external counterweight in the sewage treatment tank.

[0004] In order to achieve the above purpose, the specific technical solution of the utility model is as follows:

[0005] An aerator anti-entanglement device comprises an anti-entanglement body, a driving mechanism and a transmission lifting mechanism, wherein the length of the anti-entanglement body is greater than the minimum spacing between the suspension chain aerators at both ends of the same floating tube on the bottom of a pool, the anti-entanglement body is provided with a through hole that can vertically pass through the bronchus connected to the suspension chain aerator, and has the freedom to slide relative to the bronchus of the suspension chain aerator, the transmission lifting mechanism comprises a synchronous belt and a lifting rope, the driving mechanism is transmission-connected to the synchronous belt, the upper end of the lifting rope is fixed to the synchronous belt through a transmission guide bracket, and the lower end is fixed to the anti-entanglement body.

[0006] The driving mechanism comprises a winch and a tensioning wire rope. The winch is arranged on the shore outside the pool through a lifting support. One end of the tensioning wire rope is fixed on the winch, and the other end is fixed to the synchronous belt.

[0007] The transmission lifting mechanism also includes a guide part A, which corresponds to the position and number of the lifting rope one by one, including a floating tube clamp A and a guide roller group A. The floating tube clamp A is clamped on the floating tube. The guide roller group A is arranged on the floating tube clamp A through a fixed seat A, and includes two guide slide groove wheels a which are arranged in pairs of rollers and can rotate around their own axes. The axial direction of the guide slide groove wheel a is perpendicular to the lifting rope. The lifting rope passes through the gap between the guide roller group A and is fixedly connected to the anti-entanglement body.

[0008] The transmission lifting mechanism also includes a guide B part, the number of which is the same as that of the guide A part and they are arranged adjacent to the guide A part. The guide B part includes a floating tube clamp B and a guide roller group B. The floating tube clamp B is clamped on the floating tube, and the guide roller group B is arranged on the floating tube clamp B through a fixed seat B, including an anti-slip pressure wheel located at the top and a guide groove wheel b located at the bottom, and the axial direction of the guide roller group B is perpendicular to the extension direction of the floating tube. The synchronous belt passes through between the anti-slip pressure wheel and the guide groove wheel b from one end of the floating tube and extends to the other end of the floating tube.

[0009] The length of the lifting rope is less than the length of the bronchial tube connected below the floating tube and is greater than the distance between two adjacent groups of the guide B parts.

[0010] The length of the anti-entanglement body is greater than the overall length of the suspension chain aerators distributed on the same floating tube; the number and spacing of the through holes on the anti-entanglement body correspond to the number and spacing of the bronchial tubes arranged on the floating tube.

[0011] The extending direction of the conveying guide bracket is perpendicular to the conveying direction of the synchronous belt. The two ends of the conveying guide bracket are respectively provided with hanging ears A extending out from the two sides of the synchronous belt. The two sides of the anti-entanglement body are respectively provided with hanging ears B. The two ends of the lifting rope are fixedly connected to the hanging ears A and the hanging ears B respectively.

[0012] The anti-entanglement body is a straight rod with a counterweight.

[0013] The winch is an electric winch or a manual winch, and the driving mechanism is a group of groups arranged on the bank of the pool close to one side of the conveying guide bracket or two groups of groups symmetrically arranged at both ends of the synchronous belt.

[0014] The lifting rope, guide part A and guide part B symmetrically arranged on both sides of the floating tube form a group, and the number of groups of lifting rope, guide part A and guide part B arranged on the floating tube is less than the total number of hanging chain aerators connected to a single floating tube.

[0015] The beneficial effect of the utility model is that the utility model provides an anti-entanglement device for an aerator, and arranges the anti-entanglement main body to be autonomously raised and lowered by a driving mechanism and a transmission lifting mechanism, so that when the aerator needs to be cleaned and maintained as a whole, the anti-entanglement main body (i.e., the counterweight connecting piece) on a single floating tube can be lifted up all at once. After the staff lifts the anti-entanglement main body, all the hanging chain aerators connected to the single floating tube can be lifted up for cleaning.

[0016] The utility model uses the guide A part to guide and limit the lifting rope, thereby realizing that when the synchronous belt is put away or released, the lifting rope drives the anti-entanglement main body to perform vertical lifting / lowering movement, which can effectively prevent the anti-entanglement main body from driving the suspension chain aerator to swing in the water and cause entanglement during the lifting process; by using the guide B part and arranging the distance between two adjacent groups of guide B parts to be smaller than the length of the lifting rope, combined with the guide A part, it can effectively provide a limit for the anti-entanglement main body, limit the lifting and lowering of the anti-entanglement main body to always be performed on the bronchus, avoid it from colliding with the floating tube during the rising process, thereby extending the service life of the floating tube, the bronchus and the anti-entanglement main body.

[0017] The technical solution provided by the utility model greatly reduces the workload of removing external counterweights from a sewage treatment tank, significantly improves the cleaning and maintenance efficiency of the aeration system, and further indirectly improves the water treatment progress of the sewage treatment tank, and is suitable for wide promotion and application in the technical field of water aeration devices.

DETAILED DESCRIPTION

[0027] In order to better understand the purpose, structure and function of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings.

[0028] like Figure 1 , Figure 2 As shown, the utility model provides an aerator anti-winding device, which includes an anti-winding body 4, a driving mechanism and a transmission lifting mechanism. Each anti-winding device acts separately on each floating tube 3 in the sewage treatment pool, which is tightened at both ends by a floating tube tightening wire rope 303, and is used to limit the bronchial pipe 301 and the hanging chain aerator 5 connected to the floating tube 3. Specifically, the length of the anti-winding body 4 is greater than the minimum spacing between the hanging chain aerators 5 at both ends of the same floating tube 3 on the pool bottom 2. Preferably, in this embodiment, the length of the anti-winding body 4 is greater than the total length of the hanging chain aerators 5 distributed on the same floating tube 3. The anti-entanglement body 4 has a body length, and a through hole 7 for vertically passing through the bronchial tube 301 connected to the hanging chain aerator 5 is provided, so that the anti-entanglement body 4 arranged in series on the bronchial tube 301 has the freedom to slide relative to the bronchial tube 301 of the hanging chain aerator 5. In addition, in order to limit all the bronchial tubes 301 on a single floating tube 3 and the hanging chain aerator 5 connected thereto, in this embodiment, the number and spacing of the through holes 7 on the anti-entanglement body 4 correspond to the number and spacing of the bronchial tubes 301 arranged on the floating tube 3. In order to facilitate processing, the anti-entanglement body 4 is preferably a straight rod with a counterweight.

[0029] like Figures 4 to 6As shown, the transmission lifting mechanism includes a synchronous belt 8 and a lifting rope 9. The driving mechanism is connected to the synchronous belt 8 for driving the synchronous belt 8 to move linearly relative to the floating tube 3. The upper end of the lifting rope 9 is fixed to the synchronous belt 8 through the transmission guide bracket 10, and the lower end is fixed to the anti-entanglement body 4. When the driving mechanism drives the synchronous belt 8 to move, the anti-entanglement body 4 moves up or down relative to the bronchial tube 301 under the drive of the synchronous belt 8 and the lifting rope 9. Among them, the synchronous belt 8 can be in various forms. In this embodiment, it is preferably a toothed belt; the lifting rope 9 can be set on one side of the floating tube 3, or it can be symmetrically set on both sides of the floating tube 3. In this embodiment, it is preferably symmetrically set on both sides of the floating tube 3, and two symmetrical lifting ropes 9 form a group; in addition, in order to simplify the structure on the basis of ensuring the anti-entanglement effect of the suspension chain aerator 5, reduce the total weight of the structure and the workload and cost of production, in this embodiment, the number of groups of lifting ropes 9 is set to be less than the total number of the suspension chain aerators 5.

[0030] Further, the number of driving mechanisms can be two groups symmetrically arranged on the banks of the pool at both ends of the synchronous belt 8 or one group arranged on the bank of the pool on one side close to the conveying guide bracket 10. When two groups are set, the two groups of driving mechanisms need to be driven synchronously and the driving directions need to be the same. In this embodiment, in order to simplify the structure and simplify the operation on the basis of ensuring the technical effect, it is preferably as follows Figure 1 , Figure 3 As shown in the group, the driving mechanism in this embodiment includes a winch 11 and a tensioning wire rope 12. The winch 11 is arranged on the pool body 1 at one end of the pool bank through a lifting support 13. One end of the tensioning wire rope 12 is fixed on the winch 11, and the other end is fixed to the synchronous belt 8. The synchronous belt 8 and the winch 11 are connected together by the tensioning wire rope 12. When the synchronous belt 8 needs to be retracted, the winch 11 can be driven. The winch 11 can be in the form of an electric winch 11 or a manual foot plate, preferably a manual winch 11 with a self-locking mechanism. In addition, since the anti-entanglement body itself has a counterweight, when the anti-entanglement body 4 needs to be sunk, it only needs to unlock the self-locking mechanism of the manual winch 11, and the anti-entanglement body 4 can fall to the lowest position 21 by itself. Therefore, a driving mechanism is provided in one group. In this embodiment, it is provided on the pool body 1 on the opposite side of the blower 302 connected to the floating tube 3.

[0031] Further, such as Figure 4 , Figure 6As shown, in order to provide a limit for the lifting rope 9 so that it only drives the anti-entanglement main body 4 to make vertical movement, the transmission lifting mechanism in this embodiment also includes a guide A part, and the guide A part corresponds to the position and quantity of the lifting rope 9 one by one, specifically including a floating tube clamp A14 and a guide roller group A. The floating tube clamp A14 is clamped on the floating tube 3, including an upper clamp located at the upper half of the floating tube and a lower clamp located at the lower half of the floating tube. In this embodiment, in order to prevent the upper clamp from bending and deforming with the floating tube 3 during use, it is necessary to reinforce it with slats. Preferably, a PET plastic plate is padded between the upper clamp and the floating tube 3. The guide roller group A is arranged on the floating tube clamp A14 through a fixed seat A141, and includes two guide slide groove wheels a15 which are arranged in pairs of rollers and can rotate around their own axis. The axial direction of the guide slide groove wheel a15 is perpendicular to the lifting rope 9. The lifting rope 9 passes through the gap between the two guide slide groove wheels a15 and is fixedly connected to the anti-entanglement main body 4.

[0032] At the same time, in order to provide a limit for the synchronous belt 8 so that it only moves linearly relative to the floating tube 3 during the movement and prevents it from detaching from the floating tube 3, as shown in FIG. Figure 4 , Figure 5 , Figure 6 As shown, the transmission lifting mechanism also includes a guide B part which is arranged adjacent to the guide A part and has the same number as the guide A part and the lifting rope 9. The guide B part includes a floating tube clamp B16 and a guide roller group B. The floating tube clamp B16 is clamped on the floating tube 3. The guide roller group B is arranged on the floating tube clamp B16 through a fixed seat B161, including an anti-slip pressure wheel 17 located at the top and a guide slide groove wheel b18 located at the bottom. There is a gap between the anti-slip pressure wheel 17 and the guide slide groove wheel b18. The axial direction of the guide roller group B is perpendicular to the extension direction of the floating tube 3. The synchronous belt 8 passes through between the anti-slip pressure wheel 17 and the guide slide groove wheel b18 from one end of the floating tube 3 to the other end of the floating tube 3.

[0033] like Figures 4 to 8 As shown, in order to facilitate the fixing of the lifting rope 9, the extending direction of the transmission guide bracket 10 is perpendicular to the conveying direction of the synchronous belt 8, and the two ends of the transmission guide bracket 10 are respectively provided with hanging ears A1001 extending from the two sides of the synchronous belt 8, and the two sides of the anti-entanglement body 4 are respectively provided with hanging ears B401, and the two ends of the lifting rope 9 are respectively fixedly connected to the hanging ears A1001 and the hanging ears B401. In order to prevent the anti-entanglement body from colliding and rubbing with the bronchus 301, in this embodiment, a guide protective sleeve 19 is provided in the through hole 7 of the anti-entanglement body.

[0034] Furthermore, in order to ensure that the anti-entanglement body 4 is always on the bronchial tube 301 below the liquid level 20 during the up and down movement and does not collide with the suspension chain aerator 5 and the floating tube 3, the length of the lifting rope 9 is less than the length of the bronchial tube 301 connected below the floating tube 3 and greater than the distance between the two adjacent groups of the guide B parts. Figure 5 , Figure 6 , Figure 7 .
