Description

Technical Field

[0001] This utility model belongs to the field of air compressor technology, and in particular relates to a descaling device for air compressor units. Background Technology

[0002] An air compressor is a mechanical device that compresses and stores air. It is widely used in industrial, manufacturing, automotive repair, and household applications. By compressing air to high pressure and storing it in an air tank, an air compressor can provide the air pressure required for various equipment, tools, machines, and other applications.

[0003] A descaling device for an air compressor unit, disclosed in publication number CN209077362U, includes an electric drill and a drill rod. One end of the drill rod is fixedly connected to the electric drill, and the other end of the drill rod is externally fixedly connected to a blade or protrusion. The drill rod is hollow inside. A dust suction hole communicating with the hollow inside of the drill rod is opened on the end of the drill rod with the blade or protrusion. A brush is provided on the outer periphery of the upper part of the drill rod with the blade or protrusion. A dust suction hole communicating with the hollow inside of the drill rod is opened on the drill rod above the brush. An outlet I is provided on the upper part of the drill rod. A short pipe with an inner diameter larger than the outer diameter of the drill rod is provided outside the drill rod with outlet I. Both ends of the short pipe extend towards the center of the short pipe, and both ends of the short pipe are connected to the outer diameter of the drill rod through bearings. An outlet II is opened on the short pipe. An outlet II is connected to a discharge pipe. A negative pressure fan is provided on the discharge pipe. A receiving device is connected to the discharge pipe.

[0004] Existing descaling devices for air compressor units still have the following shortcomings:

[0005] 1. Using an electric drill to drive the blades or protrusions at the end of the drill rod to crush scale and debris inside the intercooling pipes of the air compressor, it is necessary to control the fit of the blades or protrusions to the inner diameter of the intercooling pipes of the air compressor, and it also requires extremely precise operation. Otherwise, the removal effect of scale and debris will be insufficient, or damage to the inner wall of the intercooling pipes of the air compressor will occur.

[0006] 2. During the process of vacuuming the crushed limescale debris through the suction holes on the top of the brush, larger particles of debris may easily clog the suction holes, thereby damaging the suction structure or causing some debris to not be completely removed. Utility Model Content

[0007] The purpose of this invention is to solve the problems in the existing technology that are often ineffective in removing scale and debris, or that damage the inner wall of the intercooling pipes of the air compressor, and that large particles of debris can easily clog the dust collection holes, thereby damaging the dust collection structure or causing some debris to be not completely removed. Therefore, this invention proposes a descaling device for air compressor units.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A descaling device for an air compressor unit includes: an outer fixed cover, an outer fixed cover with a first threaded groove on its inner side, an inner fixed cover inside the outer fixed cover, a second threaded groove on the outer side of the inner fixed cover, a rubber sleeve fixedly connected to the inner side of the inner fixed cover, the outer fixed cover being threaded into the second threaded groove through the first threaded groove, and a shaft tube passing through and rotatably connected inside the outer fixed cover.

[0010] Preferably, the shaft tube is fixedly connected to a flexible tube, the side of the flexible tube is provided with a plurality of through holes, the side of the flexible tube is fixedly connected with a plurality of soft steel wires, and the through holes are disposed between the plurality of soft steel wires;

[0011] Preferably, a connecting pipe is fixedly connected to the side of the outer fixing cover away from the inner fixing cover, the shaft tube is disposed inside the connecting pipe, and two side tubes are fixedly connected to the side of the connecting pipe;

[0012] Preferably, the shaft tube is fixedly connected to the side of the connecting tube in a ring array with fasteners, the fasteners extend to the outlet end of the connecting tube, and the end of the fasteners is fixedly connected to an external fixing terminal, the external fixing terminal being rotatably connected to the side of the connecting tube away from the external fixing cover.

[0013] Preferably, a motor is provided on the side of the external fixing terminal, and the output end of the motor is fixedly connected to the side of the external fixing terminal away from the external fixing cover;

[0014] Preferably, a water pump and a water delivery pump are fixedly connected to the upper surface of the motor, and the input end of the water pump and the output end of the water delivery pump are fixedly connected to two side pipes.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. This utility model, by setting a flexible hose inside the outer fixed cover, allows the hose to be pre-inserted into the air compressor water pipe during descaling. The motor drives the outer fixed terminal to rotate, which in turn drives the shaft tube and hose to rotate. The soft steel wire on the surface of the hose can scrape off the scale inside the water pipe during the rotation of the hose, without the need to deliberately control the size of the scraper or the operating method.

[0017] 2. This utility model uses a water pump to first transfer acidic or alkaline solutions from the side pipe and connecting pipe to the hose, and then delivers the solution into the water pipe through the through hole on the hose, thereby helping to dissolve and scrape off the scale. After the initial scraping, the solution and the crushed residue can be extracted through the through hole by a water pump. After that, the water supply pump and the water pump can be used to repeatedly flush the water pipe with clean water to help remove the scale. Attached Figure Description

The input end of the water pump 12 and the output end of the water delivery pump 13 are fixedly connected to two side pipes 9. The water delivery pump 13 can first transfer acidic or alkaline solutions from the side pipes 9 and the connecting pipe 8 to the hose 4, and then send the solution into the water pipe through the through hole 5 on the hose 4, thereby helping to dissolve and scrape off the scale. After the initial scraping, the solution and the crushed residue can be extracted through the through hole 5 by the water pump 12. After that, the water delivery pump 13 and the water pump 12 can also repeatedly flush the water pipe with clean water to help remove the scale.

[0031] Before descaling, the inner fixed cover 14 can be fitted onto the outside of the air compressor water pipe and the rubber sleeve 16 can be used to achieve a tight connection with the air compressor water pipe. The outer fixed cover 1 can be threaded onto the outside of the inner fixed cover 14, which can achieve a better connection between the descaling structure and the power structure.

[0032] By setting the hose 4 inside the outer fixing cover 1, when descaling, the hose 4 can be pre-inserted into the air compressor water pipe. The motor 11 drives the outer fixing terminal 10 to rotate, and then the fixing part 7 drives the shaft tube 3 and the hose 4 to rotate. The soft steel wire 6 on the surface of the hose 4 can scrape off the scale in the water pipe during the rotation of the hose 4, without having to deliberately control the scraper size and operating method.

[0033] The water pump 13 can first transfer acidic or alkaline solutions from the side pipe 9 and the connecting pipe 8 to the hose 4, and then send the solution into the water pipe through the through hole 5 on the hose 4, thereby helping to dissolve and scrape off the scale. After the initial scraping, the water pump 12 can be used to extract the solution and the crushed residue through the through hole 5. After that, the water pump 13 and the water pump 12 can also be used to repeatedly flush the water pipe with clean water to help remove the scale.
