Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a novel bidirectional skimming pipe. Background Art

[0002] With the rapid development of cities, sewage treatment plants have become an indispensable infrastructure in urban development and construction. At a time when urban land is becoming increasingly scarce, saving land resources is undoubtedly a practical issue that every construction unit must consider. The sedimentation tank is the main component of activated sludge sewage treatment technology. It is generally used to settle suspended matter or activated sludge in sewage to achieve the purpose of clarifying water quality. The most commonly used is the weekly secondary sedimentation tank. The weekly secondary sedimentation tank has a high sludge load and can obtain greater benefits with less land occupation. It is now being used more and more.

[0003] During the treatment process in the biochemical pool of the municipal sewage treatment plant, a large amount of scum will be produced and enter the next treatment process - the secondary sedimentation tank with weekly inlet and outlet. After the mud and water are separated in the secondary sedimentation tank with weekly inlet and outlet, the sludge sinks to the bottom of the pool, and the clean water and scum are on the surface of the pool. A sludge scraper is used to scrape them to the end of the pool. A scum skimmer is installed at the end. By operating the scum skimmer, the scum is regularly discharged to the outside of the pool and treated in the scum treatment facility.

[0004] The existing conventional skimmer pipe can only rotate in one direction and skim in one direction. After the secondary sedimentation tank has been running for a long time, a large amount of scum will accumulate or even accumulate at the rear end of the skimmer pipe, which is not beautiful. It may even stink after a long time of accumulation. It requires manual cleaning regularly, which is very inconvenient and affects the operation of the equipment.

[0005] In summary, in view of the defects existing in the prior art, a new type of bidirectional metal skimmer pipe is particularly needed to solve the shortcomings of the prior art. Utility Model Content

[0010] The transmission screw has its upper end connected to the flashlight integrated drive mechanism 1 and its lower end passes through the operating platform and is rotatably connected to the connecting short rod for transmitting power;

[0011] The connecting short rod has two ends respectively connected to the lifting lug and the transmission screw for transmitting driving force to the skimmer pipe body. The lifting lug is fixedly mounted on the side wall of the skimmer pipe body.

[0012] As a preferred solution of the present invention, a pre-buried steel plate is provided on the side wall of the secondary sedimentation tank, and a detachable pipe sleeve base is installed on the pre-buried steel plate to sleeve and stabilize the skimming pipe body, which is convenient for installation and maintenance.

[0013] As a preferred solution of the present invention, a nylon sleeve is provided between the skimming tube body and the tube sleeve base for flexible rotation of the skimming tube body.

[0014] As a preferred solution of the present invention, a sealing member is provided on one side of the water outlet end of the skimming pipe body, and the sealing member is arranged between the nylon sleeve and the pipe sleeve base.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Example 1

[0028] like Figures 1 to 5 As shown, a specific embodiment of a novel bidirectional skimmer pipe according to the utility model includes:

[0029] The skimmer pipe body 9 is arranged in the secondary sedimentation tank for skimming, and a plurality of slag suction openings 10 for skimming are equidistantly opened on its surface, and the opening angle of the slag suction openings 10 is 75-90 degrees;

[0030] The flashlight integrated drive mechanism 1 is mounted on the base 2 via a fixed base plate 4 and is used to provide rotational driving force for the skimmer pipe body 9. The flashlight integrated drive mechanism 1 adopts a hoist that supports bidirectional rotation;

[0031] The base 2 is fixedly mounted on the operating platform 3 and is used to support the flashlight integrated drive mechanism 1. A limit sleeve 5 is fixedly mounted below the base 2 to ensure that the drive screw 6 moves vertically up and down;

[0032] The transmission screw 6 has its upper end connected to the flashlight integrated drive mechanism 1, and its lower end passes through the operating platform 3 and is rotatably connected to the connecting short rod 7 for transmitting power;

[0033] The connecting short rod 7 has two ends respectively connected to the lifting lug 8 and the transmission screw 6 for transmitting the driving force to the skimming pipe body 9. The lifting lug 8 is fixedly mounted on the side wall of the skimming pipe body 9.

[0034] An embedded steel plate 14 is provided on the side wall of the secondary sedimentation tank, and a detachable pipe sleeve base 11 is installed on the embedded steel plate 14 to sleeve and stabilize the skimming pipe body 9 for easy installation and maintenance. A nylon sleeve is provided between the skimming pipe body 9 and the pipe sleeve base 11 for flexible rotation of the skimming pipe body 9. A sealing member 12 is provided on one side of the water outlet end of the skimming pipe body 9. The sealing member 12 is provided between the nylon sleeve and the pipe sleeve base 11. A detachable pressing device 13 is provided on the outside of the sealing member 12. The pressing device 13 is connected to the pipe sleeve base 11 by bolts. The structure of the pressing device 13 is cylindrical with a flange, such as Figure 3 As shown, the connection is fixed by bolts, and the end thereof is a bevel, which is convenient for assembling and clamping the seal 12, and is used to tighten the seal 12 to ensure the sealing effect.

[0035] The material of the transmission screw 6 is 2Cr13, and the material of the limit sleeve 5, the connecting short rod 7, and the skimming pipe body 9 are all made of stainless steel 304.

[0036] The working principle of the utility model: The utility model uses a flashlight integrated drive mechanism 1 as a power source, a transmission screw 6 and a connecting short rod 7 as a power transmission mechanism. When the drive mechanism is started, the transmission screw 6 rotates and lifts, and the connecting short rod 7 transmits power to the lifting ear 8, and the lifting ear 8 drives the skimming pipe body 9 to rotate accordingly. A plurality of slag suction openings 10 are equidistantly provided on the surface of the skimming pipe body 9. These openings can effectively capture and skim off the slag in the secondary sedimentation tank during the rotation process. Since the drive mechanism supports bidirectional rotation, the skimming pipe body 9 can also be realized. Rotation in both forward and backward directions avoids the problem of scum accumulation at the rear end of the skimming pipe. The skimming pipe body 9 is installed on the side wall of the secondary sedimentation tank through the embedded steel plate 14 and the pipe sleeve base 11. This installation method facilitates the disassembly and replacement of the skimming pipe, reducing maintenance costs. The coordinated use of the seal 12 and the clamping device 13 further enhances the sealing effect between the skimming pipe and the pipe sleeve base, preventing leakage problems. The structure of the clamping device 13 is a cylindrical flange, which is fixed by bolts. The end is a sloped surface, which is convenient for assembling and clamping the seal 12.

[0037] The hand-operated integrated driving mechanism 1 uses a hand-operated integrated door opener or motor with a hand wheel commonly found on the market, which can be driven electrically or manually. It belongs to the existing technology and will not be described in detail.

[0038] The components in this article are all universal standard parts or components known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods, so they will not be described in detail here.

[0039] Although the specific embodiments of the present invention are described in detail above, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by ordinary technicians in this field, various changes can be made without departing from the purpose of the present invention. Modifications or deformations that do not involve creative work are still within the scope of protection of the present invention.
