Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of sewage treatment and relates to a liftable aeration system. BACKGROUND

[0002] The aeration system is a key device in the sewage treatment process and is often arranged at the bottom of an aeration tank for use, and the aeration directly affects the effect of sewage treatment. When the aeration system needs to be repaired, the aeration system needs to be taken out from the aeration tank as a whole, or the sewage in the aeration tank needs to be completely discharged and emptied. If the sewage is completely discharged, it is time-consuming and laborious.

[0003] Therefore, a complete set of liftable aeration device is designed, and a Chinese patent is applied for, with the application number 202011116503.7 and the publication number 112125391A. The complete set of liftable aeration device comprises a rectangular aeration frame, an aeration membrane tube arranged on the aeration frame, a lifting system for lifting the aeration frame, and at least one set of fixing mechanism for locking the aeration frame underwater. The fixing mechanism comprises an upper guide rod, a lower guide rod and a guide ear sleeve, the upper end of the guide ear sleeve is hinged with a movable buckle, the lower guide rod is provided with a insertion hole corresponding to the buckle, the buckle can be inserted into or separated from the insertion hole, and the two wedges are locked or separated by adjusting the bolt at the upper end of the upper guide rod. When the aeration frame is sinking, the bolt at the upper end of the upper guide rod is adjusted first, so that the upper guide rod moves upward relative to the lower guide rod, the insertion hole is expanded to the extent that the buckle can be inserted, and after the buckle is swung into the insertion hole under the action of its own gravity, the upper guide rod is lowered again to reduce the size of the insertion hole to lock the aeration frame.

[0004] In the actual use process of the aeration device, the upper guide rod needs to be lifted and then lowered every time for replacement or repair, which is inconvenient to operate. In addition, the buckle is affected by the water buoyancy of the pool, and only relies on its own gravity, so it is difficult to ensure that it can be inserted into the insertion hole at the first time. If the upper guide rod is lowered before the buckle is inserted into the insertion hole, the aeration frame cannot be fixed, and needs to be re-operated, which is relatively cumbersome. SUMMARY

[0005] The purpose of the present application is to solve the problem of inconvenient disassembly and assembly of the existing liftable aeration device.

[0006] The purpose of the present application can be achieved by the following technical scheme:

[0007] The application relates to a lifting type aeration system, which comprises an aeration frame, a rope-shaped traction member I and a fixing member used for fixing at the bottom of a pool, wherein the side of the fixing member is provided with a locking hole, a guide member is fixed on the aeration frame, the guide member is provided with a locking member and an elastic member, when the aeration frame is lowered to make the locking member opposite to the locking hole, the locking member can move along the guide direction of the guide member under the elastic force of the elastic member and make the outer end of the locking member extend into the locking hole, and one end of the traction member I is fixed to the inner end of the locking member.

[0008] When the lifting type aeration system is installed, the fixing member is fixed at the bottom of the aeration pool, and then the aeration frame is lowered to the bottom of the aeration pool by manual or electric mode. During the lowering process, the locking member extends outward along the guide direction of the guide member under the elastic force of the elastic member and can abut against the fixing member until the aeration frame is lowered to the position where the locking member is opposite to the locking hole, the outer end of the locking member extends into the locking hole, and the position limitation between the aeration frame and the fixing member is realized. When dismounting is needed, the other end of the traction member I is pulled to make the locking member move along the guide direction of the guide member and compress the elastic member, the outer end of the locking member is out of the locking hole, and the position limitation between the aeration frame and the fixing member is released. Then, the whole aeration frame is lifted by electric or manual mode.

[0009] During the dismounting process of the lifting type aeration system, the locking member can realize stable movement in one direction under the joint action of the elastic member and the guide member, the influence of the pool water buoyancy on the position locking is reduced, the locking member can extend into the position limitation at the first time when the position of the locking member is opposite to that of the locking hole, repeated operation is avoided, and during the whole locking process, no other operation is needed except lowering the aeration frame, the installation procedure is simplified, and the installation operation is facilitated; meanwhile, the unlocking can be realized only by pulling the traction member I, so that the dismounting process of the aeration system is also relatively convenient.

[0010] In the lifting type aeration system, the aeration frame and / or the fixing member are further provided with a guide structure which can guide the lowering direction of the aeration frame. The guide structure can guide the lowering direction of the aeration frame, ensure that the position of the locking member is opposite to that of the locking hole, improve the efficiency of the position locking, avoid repeated adjustment of the position of the aeration frame, and facilitate the operation.

[0011] In the lifting type aeration system, the guide structure comprises a rope-shaped traction member II, the fixed member is provided with a reversing part II, the reversing part II is located below the locking hole, one end of the traction member II is fixed on the aeration frame, the fixed position of the traction member II and the aeration frame is higher than the position of the reversing part II, and the other end of the traction member II can pass the reversing part II and extend upward. After passing the reversing part II, the traction member II extends upward above the aeration tank and is in a V shape, the direction of the traction member II is changed, when the aeration frame moves downward, the other end of the traction member II is pulled upward, the aeration frame is pulled downward and moves gradually to the direction of the reversing part II, and the aeration frame is guided to lock downward. Here, the traction member II can guide and drive the aeration frame to overcome the buoyancy and move downward, one object has two functions, the components of the aeration system are reduced, the structure is simplified, and the operation is facilitated.

[0012] In the lifting type aeration system, the reversing part II is a hanging ring in a circular ring shape, when the outer end of the locking member extends into the locking hole, the locking member and the reversing part II are located on both sides of the locking hole, and the other end of the traction member II can pass through the inner hole of the hanging ring. The locking hole is located between the aeration frame and the hanging ring, so that the angle of the traction member II relative to the vertical direction is larger, when the traction member II is pulled, the aeration frame always has a moving trend of moving to the fixed member, the outer end of the locking member cannot extend into the locking hole after the outer end extends out, the stability and reliability of the position cooperation between the locking member and the locking hole are improved by one pulling, and the operation is facilitated.

[0013] In the lifting type aeration system, the aeration frame is provided with a reversing part I near the inner end of the locking member, the extension direction of one end of the traction member I connected with the locking member is consistent with the moving direction of the locking member, and the other end of the traction member I can pass the reversing part I and extend upward. Through the arrangement of the reversing part I, when the traction member I is pulled, the force can be applied to the locking member along the moving direction of the locking member, the position locking between the locking member and the locking hole is unlocked by one pulling, the unlocking efficiency is improved, and the operation is facilitated.

[0014] In the lifting type aeration system, the locking member is column-shaped and horizontally arranged in the guide member, the outer end surface of the locking member is an inclined surface, and the upper part of the outer end of the locking member is more outwardly protruding than the lower part. The inclined surface makes the locking member smoothly retract into the guide member when the aeration frame moves downward to be adjacent to the fixed member, avoids the situation of being stuck, and facilitates the operation.

[0015] In the lifting type aeration system, the guide member is in a cylindrical shape and horizontally arranged, the inner side of the inner end of the locking member has a protruding annular stopper, the width of the inner end of the locking member is smaller than that of the outer end and an annular stop shoulder is formed on the outer side of the middle part of the locking member, the inner end of the locking member passes through the stopper, and the stopper can abut against the stop shoulder, and the two ends of the elastic member act on the stopper and the locking member. Through the abutment between the stopper and the stop shoulder, the locking member can be prevented from being pulled out from the other end of the guide member, and the pulling member can serve as a force receiving member for lifting the entire aeration frame, thus simplifying the structure and facilitating the operation.

[0016] In the lifting type aeration system, the fixing member comprises a vertically arranged plate-shaped fixing plate and a base fixed to the lower end of the fixing plate, the locking hole is arranged in the middle part of the fixing plate in a horizontal direction, the bottom of the fixing plate has a horizontally protruding supporting part for abutting against the aeration frame, and the upper part of the fixing plate has a flared part curved away from the supporting part. The flared part of the upper part of the fixing plate is used for guiding the aeration frame to move smoothly between the two fixing members when the aeration frame is lowered, and the supporting part is used for limiting the lowering distance of the aeration frame, and in cooperation with the distance between the locking hole, the position of the locking member can be opposite to the locking hole when the aeration frame abuts against the supporting part, thus facilitating the positioning.

[0017] In the lifting type aeration system, the base comprises a connecting plate arranged horizontally below the fixing plate and a vertically arranged fastening member one and a fastening member two, the connecting plate has a long strip-shaped adjusting groove, the upper end of the fastening member one is fixedly connected with the fixing plate, the lower end of the fastening member one passes through the adjusting groove and the fastening member one can be positioned after moving back and forth along the adjusting groove, and the fastening member two passes through the connecting plate and is fixedly connected with the connecting plate. The fastening member two is used for fixing the connecting plate and the bottom of the aeration tank, and inevitably, there will be errors during the fixing. Through the arrangement of the adjusting groove, the position of the fixing plate can be adjusted relative to the fastening member two, thus reducing the precision requirement during the fixing and facilitating the installation.

[0018] Compared with the prior art, the lifting type aeration system has the following advantages:

[0019] 1. The locking member on the aeration frame can realize stable movement in the horizontal direction under the joint action of the elastic member and the guide member, the influence of the pool water buoyancy on the position locking of the aeration frame is reduced, the position locking between the locking member and the locking hole can be released at the first time, the repeated operation is avoided, and in the entire locking process, no other operation is required except for lowering the aeration frame itself, thus simplifying the installation operation procedure and facilitating the installation operation.

[0020] 2. The position locking between the aeration frame and the fixing member can be released by only pulling the pulling member one upward, and the unlocking operation is convenient.

[0021] 3. The first traction component can be used as both an unlocking component and a force-bearing component for lifting the aeration frame. The second traction component can be used as both a guide component for guiding the movement of the aeration frame and a force-bearing component for pulling the aeration frame downward against buoyancy. Both components can serve two purposes, simplifying the structure and operation procedures and making operation more convenient.

[0022] 4. The fixing plate used to lock the aeration frame in this liftable aeration system is fixed to the bottom of the pool only by fastener two. In actual use, it can be fixed at any position on the bottom of the pool as needed. Thus, the same aeration pool can be divided into several independent units, and each independent unit can hold one liftable aeration system. This reduces the volume and weight of each liftable aeration system, thereby reducing the driving force required for raising and lowering the aeration frame. This makes it possible to manually raise and lower the aeration frame in large aeration pools, reducing system costs and maintenance costs. Attached Figure Description

[0032] The base is also provided with a reversing portion two 8, the center position of which and the center of the locking hole 31 are located in the same plane. Preferably, the center positions of the two reversing portion twos 8 and the two locking holes 31 on the two fixing members 3 are also located in the same plane. The height position of the reversing portion two 8 is lower than the height positions of the locking hole 31 and the supporting portion 34. In this embodiment, the reversing portion two 8 is a round ring-shaped lifting ring, the lower part of which is fixed to the connecting plate 35, and the reversing portion two 8 is located on the other side of the locking hole 31 relative to the aeration stand 1.

[0033] The aeration stand 1 is fixed with a horizontally arranged square cylindrical guide member 4, and the arrangement direction of the guide member 4 is the same as the distribution direction of the two fixing members 3. The guide member 4 is provided with an elastic member 6 and a coaxially arranged column-shaped locking member 5. The locking member 5 can move along the guide direction of the guide member 4 under the elastic force of the elastic member 6, so that the outer end of the locking member 5 extends out of the guide member 4 and extends into the locking hole 31. One end of the pulling member one 2 is fixed to the inner end of the locking member 5.

[0034] Specifically, the guiding member 4 has a protruding annular stopper on the other end inner side relative to the fixed member 3, the width of the inner end of the locking member 5 is smaller than the width of the outer end and an annular stopper 52 is formed on the outer side of the middle part of the locking member 5, the inner end of the locking member 5 passes through the stopper from inside, and the stopper can abut against the stopper 52 to prevent the locking member 5 from coming out, the elastic member 6 is a spring, which is sleeved on the outer side of the inner end of the locking member 5, and the two ends of the elastic member 6 abut against the stopper and the stopper 52 respectively. The outer end face of the locking member 5 is an inclined surface 51, and the upper part of the outer end of the locking member 5 is closer to the fixed member 3 than the lower part.

[0035] The reversing part one 9 is fixed on the aeration rack 1 on the other side of the guiding member 4 relative to the fixed member 3, the extension direction of the one end of the traction member one 2 connected with the locking member 5 is consistent with the moving direction of the locking member 5, and the other end of the traction member one 2 passes around the reversing part one 9 and extends upward. In this embodiment, the traction member one 2 is a steel wire rope, and the reversing part one 9 is a guide roller rotatably connected on the aeration rack 1.

In this embodiment, the traction member two 7 is a steel wire rope.

[0037] When installing the lifting type aeration system, at least two fixed members 3 are fixed on the bottom of the aeration tank through fasteners two 37 respectively, when the distance between the two fixed members 3 after being fixed is not suitable, the clamping state between the fastener one 36 and the connecting plate 35 can be loosened, the relative distance between the two fixed members 3 is adjusted along the length direction of the adjusting groove, and then the clamping is locked again.

[0038] Then, the traction member one 2 is kept in the stressed state, that is, the traction member one 2 pulls the locking member 5 to shrink into the guiding member 4 against the elastic force of the elastic member 6. The other end of the traction member two 7 is pulled upward, the reversing part two 8 is reversed, the downward moving force is applied to the aeration rack 1, and the aeration rack 1 starts to descend.

[0039] During the descending process of the aeration rack 1, the flared part 33 in the form of a circular arc on the upper part of the fixed plate 32 coarsely limits the position of the aeration rack 1, and the aeration rack 1 is gradually adjusted to the appropriate position in the descending process through the guiding of the side wall in the form of a circular arc.

[0040] When the aeration rack 1 is lowered to abut on the supporting part 34, the position of the locking piece 5 and the locking hole 31 are opposite, the traction piece 2 is loosened, the outer end of the locking piece 5 is extended into the locking hole 31 under the elastic force of the elastic piece 6, and the limiting between the aeration rack 1 and the fixing piece 3 is realized. Here, in order to ensure the locking efficiency of the locking piece 5 and the locking hole 31, the horizontal width of the locking hole 31 is greater than the width of the locking piece 5, for example, the width of the locking hole 31 is 1.5 times the width of the locking piece 5, etc.
