Description

Technical Field

[0001] This utility model relates to the field of air compressor storage tank technology, specifically to an air compressor storage tank drainage device. Background Technology

[0002] An air compressor receiver tank, also known as a compressed air storage tank, is a pressure vessel specifically designed for storing compressed air.

[0003] For example, patent CN221014954U discloses a drainage device for an air compressor storage tank, including a valve body. A filter chamber, cylindrical in shape, is located at one end of the valve body inlet. A filter core is located inside the filter chamber near the valve body inlet, and a filter screen is located inside the filter chamber away from the valve body inlet. The side surfaces of both the filter core and the filter screen are in contact with the inner wall of the filter chamber. An end cap connected to the filter chamber is located at the end of the filter chamber away from the filter core. A drain port is located at the bottom of the filter chamber, and an inlet pipe for connecting to the air compressor storage tank is located on the end cap. This invention, by setting up a filter chamber, filter core, and filter screen, first filters and intercepts impurities such as rusted metal shavings in the air compressor storage tank through the filter screen, and then further intercepts them through the filter core, further reducing the amount of grease and impurities in the oil-water mixture flowing into the valve body and causing damage to the drain valve.

[0004] However, although the aforementioned air compressor tank drainage device is equipped with a filter structure, after long-term use, various impurities and dirt will accumulate on the internal drain pipe. The continuous accumulation of these impurities and dirt will not only reduce the inner diameter of the drain pipe, causing poor drainage, but may also corrode the inner wall of the pipe, reduce the service life of the drain pipe, and affect the normal drainage operation of the air compressor tank. Utility Model Content

[0005] The present invention aims to solve the problems mentioned in the background art by providing a drainage device for an air compressor storage tank.

[0006] The specific technical solution is as follows:

[0007] An air compressor storage tank drainage device includes: a drain pipe connected to and installed at the center of the lower surface of the air compressor storage tank, a support leg installed on the lower surface of the air compressor storage tank, a valve installed on the drain pipe near a section of the air compressor storage tank, a cleaning assembly detachably installed at one end of the drain pipe, and a bonding block attached to the outside of the drain pipe, the bonding block being detachably connected to the cleaning assembly, the bonding block being U-shaped.

[0008] As a preferred embodiment of this utility model, both ends of the lower surface of the bonding block are fixedly connected to a fixing plate, and both ends of the upper surface of the fixing plate are provided with mounting holes.

[0009] As a preferred embodiment of this utility model, the pipe cleaning assembly includes a clamping pipe, which is tightly fitted onto a section of the outer periphery of the drain pipe by an interference fit. Connecting plates are fixedly installed on both sides of the clamping pipe, and the connecting plates and the fitting block have the same threaded holes at both ends, with positioning bolts threaded into the threaded holes.

[0010] As a preferred embodiment of this utility model, a base is fixedly installed at one end of the lower surface of the clamping tube, and another set of threaded holes is opened at both ends of the upper surface of the base.

[0011] As a preferred embodiment of this utility model, the clamping tube is provided with an inner insertion tube, and the gap formed between the inner insertion tube and the clamping tube can be used to tightly connect the drain pipe, and a sealing ring is installed in the gap.

[0012] As a preferred embodiment of this utility model, a scraper ring is installed on the outer wall of the end of the inner tube that is inserted into the drain pipe.

[0013] This utility model has the following beneficial effects:

[0014] 1. The air compressor tank drainage device provided by this utility model, through the design of the cleaning assembly, the fitting block, and the drain pipe, allows for pre-adjustment of the fitting block's position on the drain pipe surface during air compressor tank drainage. Since the fitting block and the fixing plate are fixedly connected with a gap for easy insertion, the fitting block adheres to the outer surface of the drain pipe. Then, bolts are inserted into the mounting holes on the upper surface of the fixing plate to fix the fixing plate to the ground, ensuring the fitting block is stably attached to the outer surface of the drain pipe. Next, the cleaning assembly is inserted into the drain pipe to clean the dirt inside, causing the cleaned dirt to accumulate in the drain pipe. Then, by opening the valve, water flows from the air compressor tank into the drain pipe, flushing away the accumulated dirt. Furthermore, the cleaning assembly is easy to disassemble and clean, effectively cleaning the dirt inside the drain pipe and ensuring that impurities will not affect the pipe's lifespan during long-term use.

[0015] 2. The air compressor tank drainage device provided by this utility model, through the design of a clamping pipe, an inner insert pipe, a sealing ring, and a scraper ring, facilitates the installation and use of the cleaning components. The clamping pipe and the drain pipe are aligned. During installation, the inner insert pipe inside the clamping pipe is inserted into the drain pipe, while the clamping pipe fits against the outside of the drain pipe, allowing the drain pipe to be inserted into the gap formed between the inner insert pipe and the clamping pipe. This ensures that water can flow out from the inner insert pipe inserted into the drain pipe. After insertion, the connecting plates and fitting blocks installed on both sides of the clamping pipe are connected by positioning bolts, improving installation stability and preventing displacement due to excessive water flow. When the inner insert pipe is inserted, the scraper ring installed on its surface scrapes the inner wall of the drain pipe, causing dirt inside the drain pipe to fall off. Then, by opening the valve, water flows from the air compressor tank into the drain pipe, causing the fallen dirt to be discharged from the inserted inner insert pipe. This prevents the accumulation of impurities and dirt, which could cause poor drainage and corrosion of the pipe's inner wall, ensuring the normal operation of the air compressor tank's drainage function and facilitating disassembly and cleaning of the drain pipe by personnel.

[0029] Example 1

[0030] The air compressor storage tank drainage device provided in this embodiment, such as Figures 1-5 As shown, the assembly includes: a drain pipe 102 connected to the center of the lower surface of the air compressor storage tank 1; a support leg 101 installed on the lower surface of the air compressor storage tank 1; a valve 103 installed near the section of the drain pipe 102 close to the air compressor storage tank 1; a cleaning assembly 2 detachably installed at one end of the drain pipe 102; and a bonding block 3 attached to the periphery of the drain pipe 102, which is detachably connected to the cleaning assembly 2. The bonding block 3 is U-shaped. Fixing plates 301 are fixedly connected to both ends of the lower surface of the bonding block 3, and mounting holes 302 are provided at both ends of the upper surface of the fixing plate 301.

[0031] Through the design of the cleaning assembly 2, the bonding block 3, and the drain pipe 102, when draining the air compressor's air tank, the position of the bonding block 3 on the surface of the drain pipe 102 can be adjusted beforehand. Since the bonding block 3 and the fixing plate 301 are fixedly connected, and there is a hole between them for easy insertion, the bonding block 3 is made to fit against the outer surface of the drain pipe 102. Then, bolts are inserted into the mounting holes 302 on the upper surface of the fixing plate 301 to fix the fixing plate 301 to the ground, ensuring that the bonding block 3 can be stably bonded to the surface. The cleaning assembly 2 is inserted into the drain pipe 102 through the outer surface of the drain pipe 102 to clean the dirt inside the drain pipe 102. The cleaned dirt accumulates in the drain pipe 102. Then, the drain is drained by opening the valve 103. The water flows from the air compressor storage tank 1 into the drain pipe 102 to flush away the accumulated dirt. The cleaning assembly 2 is easy to disassemble and clean, and can effectively clean the dirt inside the drain pipe 102, ensuring that impurities will not affect the life of the pipe during long-term use.

[0032] Example 2

[0033] The air compressor storage tank drainage device provided in this embodiment, such as Figures 3-5 As shown, the system includes: a cleaning assembly 2 comprising a clamping pipe 201, which is tightly fitted onto a segment of the drain pipe 102 via an interference fit. Connecting plates 203 are fixedly installed on both sides of the clamping pipe 201. Both ends of the connecting plates 203 and the fitting block 3 have identical threaded holes, with positioning bolts 204 threaded into these holes. A base 202 is fixedly installed at one end of the lower surface of the clamping pipe 201, and another set of threaded holes is provided at both ends of the upper surface of the base 202. An inner insertion tube 205 is provided inside the clamping pipe 201. The gap formed between the inner insertion tube 205 and the clamping pipe 201 allows for a tight connection to the drain pipe 102, and a sealing ring 207 is installed within the gap. A scraper ring 206 is installed on the outer wall of the end of the inner insertion tube 205 that is inserted into the drain pipe 102.

[0034] The design of the clamping connector 201, inner insert 205, sealing ring 207, and scraper ring 206 facilitates the installation and use of the cleaning assembly 2. The clamping connector 201 and drain pipe 102 are aligned. During installation, the inner insert 205 inside the clamping connector 201 is inserted into the drain pipe 102, while the clamping connector 201 fits against the outer periphery of the drain pipe 102, allowing the drain pipe 102 to be inserted into the gap formed between the inner insert 205 and the clamping connector 201. This ensures that water can flow out from the inner insert 205 inserted into the drain pipe 102. After insertion, the connecting plates 204 installed on both sides of the clamping connector 201 are secured using positioning bolts 204. 3 and the bonding block 3 are connected to improve the stability of the installation and prevent displacement due to excessive water flow. When the inner tube 205 is inserted, the scraper ring 206 installed on its surface scrapes the inner wall of the drain pipe 102, causing the dirt in the drain pipe 102 to fall off. Then, the drain is drained by opening the valve 103. The water flows from the air compressor storage tank 1 into the drain pipe 102, and the fallen dirt is discharged from the inserted inner tube 205. This prevents the accumulation of impurities and dirt, which may cause poor drainage and corrosion of the inner wall of the pipe. It ensures the normal operation of the air compressor storage tank and makes it convenient for staff to disassemble and clean the drain pipe 102.

[0035] In summary, the air compressor tank drainage device provided in this embodiment has the following advantages: it facilitates cleaning of the inner wall of the drain pipe 102 of the air compressor tank, does not require workers to expend much physical effort during the cleaning process, and is easy to disassemble and clean, thereby avoiding the problem of impurities and dirt accumulation due to long-term use and not affecting the normal drainage of the air compressor tank.

[0036] In use, first adjust the position of the adhesive block 3 on the surface of the drain pipe 102. Since the adhesive block 3 and the fixing plate 301 are fixedly connected, there is a hole between them for easy insertion, so that the adhesive block 3 fits against the outer surface of the drain pipe 102. Then, insert the bolt into the mounting hole 302 on the upper surface of the fixing plate 301 to fix the fixing plate 301 to the ground, ensuring that the adhesive block 3 can be stably attached to the outer surface of the drain pipe 102. Align the clamping pipe 201 with the drain pipe 102. During installation, insert the inner insertion tube 205 provided in the clamping pipe 201 into the drain pipe 102. The clamping pipe 201 fits against the outer perimeter of the drain pipe 102, so that the drain pipe 102 is inserted into the gap formed between the inner insertion tube 205 and the clamping pipe 201, ensuring that water can flow from the drain pipe 102. The inner tube 205 in pipe 102 flows out and is connected to the connecting plate 203 and the fitting block 3 on both sides by positioning bolts 204, which further improves the stability of the clamping pipe 201 and prevents the cleaning assembly 2 from loosening or shifting during drainage. This ensures the relative position between the inner tube 205 and the drain pipe 102 is stable. When the inner tube 205 is inserted, the scraper ring 206 installed on its surface scrapes the inner wall of the drain pipe 102, causing dirt in the drain pipe 102 to fall off. The valve 103 is opened to drain water, and water flows from the air compressor storage tank 1 into the drain pipe 102, causing the fallen dirt to be discharged from the inserted inner tube 205.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
