Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and particularly relates to a buffer device for a sewage pump pipeline. Background Art

[0002] In the process of sewage treatment, sewage needs to be discharged into sewage treatment equipment. Since the sewage flow rate is fast, cavitation is easy to occur, and the sewage contains corrosive substances, which increases the friction on the pipes and equipment, affecting the service life of the sewage treatment equipment. In the prior art, in order to reduce the flow rate of sewage, the sewage is first injected into a large container to slow down, and then input into the sewage treatment equipment. By reducing the flow rate of sewage, the impact on the sewage treatment equipment is reduced. However, a large number of bubbles are easily formed, which is not conducive to sewage treatment; and it causes splashing and odor diffusion, which has an adverse effect on the surrounding environment.

[0003] After searching, in the prior art, Chinese patent application number: CN202321248238.7 discloses a sewage pipe energy dissipation device, including a buffer chamber connected to a water inlet pipe at one end and a water outlet pipe at the other end, a plurality of damping rods are pierced through the top of the buffer chamber, and the ends of all damping rods away from the buffer chamber are commonly connected to a driving mechanism for driving the damping rods to move in the buffer chamber. When sewage passes through the buffer chamber, the damping rods in the buffer chamber hinder the water flow. When a blockage occurs in the buffer chamber, the damping rods rise so that the damping rods' obstruction to the debris in the sewage disappears. Under the driving action of the sewage, the debris in the buffer chamber is discharged from the outlet pipe. When the fluid pressure sensor still determines that the pressure is higher than the high threshold 1 minute after the damping rod rises, the solenoid valve is opened, and the sewage in the buffer chamber is discharged through the discharge pipe, reducing the pressure in the buffer chamber and preventing the pipe from being blocked; after the fluid pressure sensor determines that the pressure is normal, the damping rod is reset, and the damping rod continues to dissipate the energy of the sewage flowing through the buffer chamber.

[0004] However, the device still has the following defects:

[0005] When the device consumes energy from the sewage in the buffer chamber through the damping rod, debris in the sewage is easily entangled on the damping rod. When the damping rod needs to rise, the debris entangled on the damping rod is easy to accumulate, which hinders the rise of the damping rod and affects the normal use of the device.

[0022] See also Figure 1-5 The utility model provides a technical solution: a buffer device for a sewage pump pipeline. It includes a mounting assembly, a lifting assembly, a discharge assembly and multiple groups of buffer assemblies, wherein the lifting assembly and the discharge assembly are both mounted on the mounting assembly, and the multiple groups of buffer assemblies are all mounted on the lifting assembly;

[0023] The installation assembly includes a buffer tube 110, and a water inlet pipe 120 and a drain pipe 130 are respectively installed at both ends of the buffer tube 110. The water inlet pipe 120 and the drain pipe 130 are both connected to the buffer tube 110. A controller 140 is installed on the outer wall of the buffer tube 110 close to the water inlet pipe 120. A fluid pressure sensor 150 is installed on the inner wall of the buffer tube 110 close to the water inlet pipe 120. The fluid pressure sensor 150 is electrically connected to the controller 140. Multiple groups of cutters 160 are installed on the top inner wall of the buffer tube 110, and the multiple groups of cutters 160 are respectively located on both sides of the multiple groups of buffer assemblies.

[0024] The cutter 160 on the top inner wall of the buffer tube 110 is used to cut the debris on the buffer assembly so that the debris is not easily accumulated on the buffer assembly, so that the buffer assembly can rise normally and does not affect the normal use of the device.

[0025] The lifting assembly includes a sealing box 210 , which is installed on the top of the buffer tube 110 . A box cover is detachably installed on the top of the sealing box 210 .

[0026] The detachable arrangement of the sealed box 210 and the box cover facilitates opening the sealed box 210 so as to repair or replace the parts in the sealed box 210, thereby improving the convenience of later maintenance of the buffer device.

[0027] A motor 220 and a fixing plate 240 are installed on the top of the box cover. A worm 230 is drivingly connected to the output end of the motor 220. One end of the worm 230 away from the motor 220 is rotatably connected to the fixing plate 240. The motor 220 is electrically connected to the controller 140.

[0028] The top of the box cover is rotatably connected to a rotating rod 260 , both ends of the rotating rod 260 are open structures, and a worm wheel 270 is installed at one end of the rotating rod 260 , and the worm wheel 270 is meshed with the worm 230 .

[0030] The top of the box cover is threadedly connected to a threaded rod 250, and a plurality of groups of limiting grooves 251 are provided on the side walls of the threaded rod 250. The plurality of groups of limiting grooves 251 are equidistantly arranged in a ring shape with the central axis of the threaded rod 250 as the center, and the plurality of groups of limiting blocks 271 are slidably connected to the plurality of groups of limiting grooves 251, respectively.
