Description

Technical Field

[0001] This invention relates to the field of cooler cleaning technology, and in particular to a special tool for cleaning a screw air compressor tubular water circulating cooler. Background Technology

[0002] Our plant's second-phase ash removal air compressor is a CompAir L250-7.5W oil-injected screw air compressor with a speed of 1485 r / min and a power supply of V / ph / Hz = 6000 / 3 / 50. The compressor's oil cooler is water-cooled, using the plant's circulating water. The cooler is a shell-and-tube water-oil heat exchanger. Due to the high amount of impurities in the plant's circulating water, the pre-filter cannot completely remove all impurities, leading to tube blockage after a period of operation. This reduces the cooler's heat exchange efficiency, causing the compressor to overheat and shut down. In this situation, maintenance personnel need to clean the cooler regularly. The cooler is 1.8m long and the tube diameter is 10mm. Due to the long length and small diameter of the tubes, it brings great difficulties to the maintenance personnel in unblocking and cleaning. Although chemical cleaning is fast, it will cause permanent damage to the equipment. Now, a special electric cleaning and unblocking tool has been made according to the length and size of the tubes to facilitate the cleaning operation of maintenance personnel, effectively reduce the labor intensity of workers, and prevent cooler damage caused by improper unblocking and cleaning methods.

[0003] Existing air compressor cooler cleaning tools are operated manually, which is time-consuming and labor-intensive. The friction process generates heat and can easily damage the copper pipes of the cooler. Since the air compressor circulating water contains a lot of impurities, the worker needs to repeatedly push and pull the cooler during the cleaning process, which is labor-intensive and takes a long time. Therefore, it is necessary to improve the tools. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0020] As a preferred embodiment of the special cleaning tool for the screw air compressor tubular water circulating cooler of the present invention, the pull plate is composed of a pressing plate and an installation rope. The top of the pressing plate is connected to a third flexible spring, the bottom of the pressing plate is connected to the installation rope, and the bottom of the installation rope passes through the movable block and is fixedly connected to the outer wall of the drill rod housing.

[0021] As a preferred embodiment of the special cleaning tool for the screw air compressor tubular water circulating cooler of the present invention, the scraper plate is provided with three sets of scraping plates at the top, the tops of the three sets of scraping plates are all pointed, and the three sets of scraping plates are embedded and movably connected inside the brush.

[0022] As a preferred embodiment of the special cleaning tool for the screw air compressor tubular water circulating cooler of the present invention, the movable blocks are provided in two sets, and the two sets of movable blocks are equidistantly distributed on the upper and lower sides of the drill rod shell. Each set of movable blocks consists of five blocks, and the bottom ends of the blocks are all hinged to the drill rod shell.

[0023] As a preferred embodiment of the special cleaning tool for the screw air compressor tubular water circulating cooler of the present invention, wherein: the middle end of the movable block is hinged to the drill rod housing, the movable block is rectangular in shape, and a cavity is opened inside the upper end of the movable block.

[0024] The beneficial effects of this invention are as follows: This invention, through the cooperation of the contact module and the cleaning module, cleans impurities of varying degrees inside the copper tubes of the cooler. When cleaning impurities that are relatively easy to clean inside the copper tubes, the electric drill drives the drill rod housing to rotate. The drill rod housing causes the brush on the top of the inclined movable block to directly clean the inner wall of the copper tube. When encountering impurities that are difficult to clean, the rotating disc causes the pull rope to pull the push rod, causing the movable block to rotate and gradually become vertical. At this time, the movable block will provide support for the bottom of the brush. At the same time, the pull plate will pull the air at the lower end of the fixed tube cavity, allowing it to enter the interior of the corrugated tube through the connecting pipe. After the corrugated tube expands, it pushes the bottom of the scraper plate upward. When the drill rod housing rotates, the top of the scraper plate will scrape the impurities on the inner wall of the copper tube. Through the cooperation of the movable block, the contact module, and the push rod, and the switching between the two modes, the cleaning effect of the cooler copper tubes is greatly improved, while saving the labor intensity increased by repeated manual cleaning.

[0025] This invention uses a water replenishment module and a movable block to clean the relatively viscous impurities inside the copper tubes of the cooler. When the movable block is pulled by the push-pull rod and gradually rotates, the outer wall of the movable block will squeeze the pressure block. After being squeezed, the pressure block will compress the sponge block, allowing the water inside to enter the brush through the flow pipe, thus wetting the inside of the brush and improving the cleaning effect of impurities.

[0026] This invention, through the cooperation of a pull-back assembly and an arc-shaped corrugated pipe structure, is suitable for cleaning impurities inside the curved area of ​​a cooler's U-shaped tube. When the push-pull rod is pulled towards the limiting module, the end of the push-pull rod away from the pull rope moves inside the drill rod housing, compressing the air in the area on the left side of the fixed plate. This air is forced through the two connecting pipes into the interior of the arc-shaped corrugated pipe, causing it to expand and gradually take on an arc shape, similar to a quarter circle. This allows the curved and expanded arc-shaped corrugated pipe to adapt to the design of the U-shaped tube inside the cooler, enabling cleaning of both the fixed tube (a straight pipe) and the curved parts of the U-shaped tube, thus improving overall applicability.

[0027] This invention relates to a tool for cleaning air compressor coolers that can protect the coolers during the cleaning process, reduce the workload of workers, and ensure the occupational health of employees in the workplace. To solve the problem of time-consuming and labor-intensive cleaning of air compressor coolers in the second phase, a special tool for cleaning air compressor coolers was designed based on on-site measurements.

[0041] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0042] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0043] Example 1

[0044] Reference Figures 1-5 This is the first embodiment of the present invention, which provides a special tool for cleaning a screw air compressor tubular water circulating cooler, comprising:

[0045] The active module 100 includes a drill pipe housing 101 and active slots 102 disposed at the upper and lower ends of the drill pipe housing 101.

[0046] Arc-shaped bellows 200 is connected to one end of drill pipe housing 101;

[0047] The limiting module 300 includes a connecting shaft 303 disposed inside the drill pipe housing 101, a wheel 301 disposed on the connecting shaft 303, and a locking block 302 disposed on the wheel 301;

[0048] The cleaning module 400 includes a movable block 401 disposed on the drill pipe housing 101, a brush 403 disposed on the movable block 401, and a scraper 402.

[0049] The water replenishment module 500 includes a sponge block 501 disposed on the movable groove 102, a pressing block 502 disposed on the sponge block 501, a spring telescopic cylinder 503 disposed on the pressing block 502, and a flow pipe 504 disposed on the drill pipe housing 101.

[0050] The moving module 600 includes a push-pull rod 601 disposed inside the drill pipe housing 101, a pull-back assembly 602 and a pull rope 603 disposed on the push-pull rod 601;

[0051] The abutment module 700 includes a second flexible spring 701 disposed inside the movable block 401, a bellows 702, a fixed tube 703, and a connecting tube 704 disposed at the bottom of the inner cavity of the movable block 401, a pull plate 705 disposed inside the fixed tube 703, and a third flexible spring 706.

[0052] The pullback assembly 602 includes a fixing plate 602a that is sleeved on the outer wall of the push-pull rod 601. The fixing plate 602a is fixedly connected to the inner wall of the drill pipe housing 101. Both the upper and lower ends of the outer wall of the fixing plate 602a are fixedly connected to connecting pipes 602b that communicate with the inside of the arc-shaped corrugated pipe 200. A first flexible spring 602c that is movably sleeved on the outer wall of the fixing plate 602a away from the pull rope 603 is fixedly connected to the outer wall of the push-pull rod 601. The end of the first flexible spring 602c away from the fixing plate 602a is fixedly connected to the push-pull rod 601. When the push-pull rod 601 moves to one side of the limiting module 300, it will cause the push-pull rod 601 to move away from the pull rope 603. One end moves inside the drill pipe housing 101, which compresses the air in the left area of ​​the fixed plate 602a, causing it to enter the interior of the arc-shaped bellows 200 through the two connecting pipes 602b. Due to the continuous pulling of the push-pull rod 601, the arc-shaped bellows 200 will expand. After its interior is filled with air, it will gradually take on an arc shape, similar to a quarter circle. This allows the curved and expanded arc-shaped bellows 200 to fit the U-shaped tube design inside the cooler, enabling cleaning of the interior of the fixed pipe (a straight pipe) and the curved parts of the U-shaped tube, thus improving the overall applicability.

[0053] The connecting shaft 303 is connected to the bearing on the inner wall of the drill pipe housing 101. The outer wall of the connecting shaft 303 located inside the drill pipe housing 101 is sleeved with the pull rope 603. The locking block 302 is locked inside the wheel 301. The outer wall of the drill pipe housing 101 has a slot corresponding to the wheel 301 that matches the locking block 302. Rotating the wheel 301 causes the pull rope 603 to wind around its surface through the connecting shaft 303. The pull rope 603 pulls the push rod 601 and drives the movable block 401 to move to the corresponding position. At the same time, through the cooperation of the locking block 302 and the slot on the outer wall of the drill pipe housing 101, when the rotation moves to the appropriate position, the locking block 302 is inserted from the inside of the wheel 301 into the slot inside the drill pipe housing 101, which will fix the limiting module 300.

[0054] Example 2

[0055] Reference Figures 8-10This is the second embodiment of the present invention, based on the previous embodiment. The bottom end of the movable block 401 is hinged to the outer wall of the push-pull rod 601, the top of the movable block 401 is fixedly connected to the brush 403, the interior of the upper end of the movable block 401 is movably connected to the scraper plate 402, the top of the scraper plate 402 extends above the movable block 401, the four corners of the bottom of the brush 403 are fixedly connected to the second flexible spring 701, and the middle of the bottom of the brush 403 is fixedly connected to the bellows 702 and the fixed tube 703 respectively. When the push-pull rod 601 moves left and right, it will cause the two movable blocks 401 located inside the drill pipe housing 101 to move left and right together. When the movable block 401 is tilted, the top of the brush 403 will sweep the impurities that are better cleaned from the inner wall of the cooler copper tube. During cleaning, when the push-pull rod 601 pulls the movable block 401 to the right, the movable block 401 will gradually change from an inclined position to a vertical position. At this time, the height of the movable block 401 will increase. At the same time, the abutment module 700 will cause the scraper 402 to move upward, so that it contacts the inner wall of the cooler copper tube. With the rotation of the subsequent electric drill, the impurities that are difficult to clean are scraped. When dealing with impurities that are easier to clean, the inclined movable block 401 will not apply too much pressure to the brush 403. The top of the brush 403 alone can achieve cleaning. When cleaning impurities that are difficult to clean, the movable block 401 gradually becomes vertical. While increasing its vertical height, it provides a bottom support force for the brush 403, which improves the brushing effect of its outer wall on the inner wall of the cooler copper tube.

[0056] The sponge block 501 is movably connected to the inner wall of the movable groove 102. The end of the sponge block 501 near the cleaning module 400 is connected to the pressure block 502, and the end of the pressure block 502 away from the sponge block 501 is in contact with the movable block 401. Spring telescopic cylinders 503 are provided at both ends of the top of the pressure block 502. The end of the spring telescopic cylinder 503 away from the movable block 401 is fixedly connected to the drill rod housing 101. The bottom end of the flow pipe 504 extends to the inner wall of the movable groove 102. Several slots are opened on both the upper and lower sides of the pressure block 502 located inside the movable groove 102. The top of the flow pipe 504 extends into the interior of the brush 403. When the movable block 401 gradually becomes vertical, its outer wall will press against the pressure block 502. The pressure pushes the sponge block 501 so that the end away from the movable block 401 is squeezed. After the sponge block 501 is squeezed, the water inside will flow out through the slot on the outer wall of the pressure block 502. The water will flow into the brush 403 through the flow pipe 504, making the brush 403 gradually wet and improving the cleaning effect. To replenish the water in the sponge block 501, the flow pipe 504 can be pulled out. The spring telescopic cylinder 503 will reset the movement of the pressure block 502 accordingly. The pressure block 502 has a slot connecting the upper and lower sides inside one end of the movable groove 102, so that the water that flows into the lower part of the movable groove 102 after being squeezed by the pressure block 502 can flow to the upper part.

[0057] Four second flexible springs 701 are provided, distributed at the four corners of the bottom of the scraper plate 402. Two sets of bellows 702 are provided, with the tops of both sets of bellows 702 fixedly connected to the bottom of the scraper plate 402 and the bottoms of both sets of bellows 702 fixedly connected to the bottom of the inner cavity of the movable block 401. The fixed tube 703 is located in the middle of the two movable blocks 401, and its bottom is fixedly connected to the bottom of the inner cavity of the movable block 401. The two sides of the bottom of the fixed tube 703 are connected to the bellows 702 through the connecting tube 704. The pull plate 705 is movably sleeved with the upper end of the inner cavity of the fixed tube 703. The bottom end of the pull plate 705 passes through the movable block 401 and is fixedly connected to the drill pipe housing 101. The top of the pull plate 705 is fixedly connected to the third flexible spring 706. The top of the third flexible spring 706 is fixedly connected to the top of the inner cavity of the fixed tube 703. The movable block 401 gradually becomes vertical, which will cause the pull plate 705 to squeeze and push the air at the lower end of the inner cavity of the fixed tube 703. The air enters the interior of the bellows 702 through the two connecting pipes 704. After the bellows 702 is filled with gas, it will gradually expand, causing its top to push the top of the scraper 402. This causes the scraper 402 to move upward from the top of the movable block 401, thereby improving the subsequent cleaning effect. It should be noted that when the pull plate 705 is pulled in conjunction with the movable block 401, the pull plate 705 does not need to descend a large distance. The bellows 702 originally contains air, and only a little air needs to enter to slightly lift it upward.

[0058] Example 3

[0059] Reference Figures 6-8 This is the third embodiment of the present invention, which is based on the previous embodiment. The pull plate 705 consists of a pressing plate and an installation rope. The top of the pressing plate is connected to the third flexible spring 706, and the bottom of the pressing plate is connected to the installation rope. The bottom of the installation rope passes through the movable block 401 and is fixedly connected to the outer wall of the drill pipe housing 101. The top of the scraping plate 402 is provided with three sets of scraping plates. The tops of the three sets of scraping plates are all pointed. The three sets of scraping plates are embedded and movably connected inside the brush 403. Due to the movement of the corrugated pipe 702, the three sets of scraping plates will move upward, so that their outer walls contact the inner wall of the cooling pipe copper pipe for subsequent scraping and cleaning. The installation rope will pull the pressing plate downward inside the fixed pipe 703 and compress and push the air at its lower end, thereby facilitating the subsequent expansion of the corrugated pipe 702.

[0060] Two sets of movable blocks 401 are provided, and the two sets of movable blocks 401 are equidistantly distributed on the upper and lower sides of the drill rod housing 101. Each set of movable blocks 401 consists of five blocks, and the bottom end of each block is hinged to the drill rod housing 101. The middle end of each movable block 401 is hinged to the drill rod housing 101. The movable block 401 is rectangular in shape, and a cavity is opened inside the upper end of the movable block 401. The hinge between the movable block 401 and the drill rod housing 101 will facilitate the subsequent rotation of the movable block 401 and limit its movement. The internal cavity design facilitates the movement of the subsequent contact module 700. The rectangular design facilitates the subsequent change of height value. When the electric drill drives the drill rod housing 101 to rotate, it will cause the drill rod housing 101 to drive the ten movable blocks 401 at both ends of its surface to rotate together, thereby greatly improving the cleaning effect on the inner wall of the cooling pipe copper tube.
