Description

Technical Field

[0001] This invention relates to the field of liquefied petroleum gas (LPG) recovery, and more particularly to a mobile LPG recovery device with purification function. Background Technology

[0002] As a widely used fuel source in households and industries, the safety and efficient utilization of liquefied petroleum gas (LPG) have always been a focus of public attention. With the increasing popularity of LPG use, the recycling, cleaning, and inspection of LPG cylinders have become crucial steps in ensuring the safe use of LPG and reducing environmental pollution.

[0003] During long-term use, household liquefied petroleum gas (LPG) cylinders may become contaminated, corroded, or damaged due to various factors (such as environmental factors and usage conditions). To ensure the safe use of LPG and prevent potential safety hazards, the stains on the outer wall of the cylinder need to be cleaned and inspected after LPG cylinder recycling. Traditional LPG cylinder recycling equipment cannot inspect the outer wall of the cylinder during cleaning because the cylinder is obstructed by the cleaning equipment and remains stationary. It is also necessary to remove the cylinder and rotate it after cleaning for inspection, which is cumbersome and has a limited scope of inspection. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing mobile liquefied gas tank recycling equipment, which has limited functionality and cumbersome procedures, and to propose a mobile liquefied gas recycling equipment with purification function.

[0005] To address the problems existing in the prior art, the present invention adopts the following technical solution: A mobile liquefied petroleum gas (LPG) recovery device with purification function includes a recovery box, a vertically movable platform in the middle of the recovery box, two support springs connecting the platform and the recovery box, and the platform for supporting LPG tanks. A cleaning device is provided on the surface of the placement platform and can move back and forth along the placement platform to clean the stains on the outer wall of the liquefied gas tank. A switching device is provided on the placement platform and is used to drive the liquefied gas tank on the placement platform to rotate. A cleaning device is provided inside the recycling bin and located on both sides of the placement platform. It is used to perform rotational cleaning of the outer wall of the liquefied gas tank, and the direction of rotation of the cleaning device is opposite to the direction of rotation of the liquefied gas tank.

[0006] Preferably, the scraping device includes a positive scraper and a reciprocating screw. Two round rods are fixedly installed in the middle groove of the placement platform. The two ends of the positive scraper are slidably connected to the round rods. A sliding rod is fixedly installed on the lower surface of the positive scraper. The reciprocating screw is rotatably installed in the middle of the groove of the placement platform and is connected to the sliding rod.

The striking component includes a spring block, which is slidably disposed in the groove of the front scraper. Two lifting rods are fixedly provided on the lower surface of the spring block, and the lower ends of the two lifting rods pass through the front scraper. The corrugated strip is fixedly installed in the groove of the placement platform, and the lower ends of the lifting rods are in contact with the corrugations of the corrugated strip. Two limiting springs are fixedly provided in the groove of the front scraper, and one end of the limiting spring is fixedly connected to the lower surface of the spring block.

[0008] Preferably, the switching device includes a drive shaft, which is rotatably mounted inside the placement platform. Two drive wheels are fixedly mounted on the drive shaft, and the drive wheels are in contact with the outer wall of the liquefied gas tank on the placement platform.

[0009] Preferably, the cleaning device includes a cleaning brush, and movable blocks are slidably provided in the grooves at both ends of the recycling bin, and both ends of the central shaft of the cleaning brush are rotatably connected to the movable blocks.

[0010] Preferably, the cleaning device further includes a connecting assembly, which includes two base plates symmetrically installed at the bottom of the recycling bin. Two pairs of first toothed plates and second toothed plates are slidably provided on each of the two base plates. Gears are rotatably provided on the upper surface of each of the two base plates. A gear meshes between each of the first toothed plates and the second toothed plates. A rectangular rod is fixedly provided on one side of each of the second toothed plates. The upper end of each rectangular rod is fixedly connected to the moving block. A rotating rod is rotatably provided on each of the first toothed plates. The upper end of the rotating rod is rotatably connected to the lower surface of the placement platform.

[0011] Preferably, the cleaning device further includes a removal component, which includes two fence frames, both of which are fixed inside the recycling bin and located on one side of the cleaning brush. A water spray pipe is fixedly provided at the upper end of each of the two fence frames, and the nozzle on the water spray pipe is located at the gap between the fence frames. A control valve is rotatably provided at one end of the water spray pipe, and a torsion spring is provided between the control valve and the water spray pipe.

[0012] Preferably, an intermittent assembly is provided between the scraping device and the switching device. The intermittent assembly includes a first turntable and a second turntable.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, after the liquefied gas cylinder is placed on the placement platform and enters the recycling box, the scraping device moves vertically along the outer wall of the cylinder to remove the stains on the outer wall of the cylinder, and the cleaning device scrubs the oil stains on the outer wall of the cylinder. Then, the cylinder is rotated along the placement platform by the switching device, so that the scraping device and the cleaning device come into contact with different outer walls of the cylinder, and the outer wall of the liquefied gas cylinder is completely cleaned, thereby improving the cleaning efficiency of the cylinder. 2. In this invention, during the scraping of the outer wall of the tank by the moving scraper in the scraping device, the spring block in the scraper will continuously tap the outer wall of the tank. By listening to the sound produced by the tapping, it is possible to determine whether there is any abnormality in the liquefied gas tank. Since the scraper is in close contact with the tank, the movement of the tank when the scraper moves along the outer wall of the tank is used to determine whether the tank is deformed, thus improving the inspection method of the tank. 3. The cleaning brush on the cleaning device is connected to the placement platform. The cleaning brush moves left and right as the placement platform moves up and down. When the cleaning brush moves outward and passes through the fence, the impurities and oil on the cleaning brush will be cleaned, keeping the cleaning brush clean and improving the cleaning efficiency of the liquefied gas tank.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] Example: This example provides a mobile liquefied petroleum gas (LPG) recovery device with purification function. See [link / reference]. Figure 1-8 Specifically, it includes a recycling bin 1, with a movable platform 11 in the middle. Two support springs 12 connect the platform 11 to the recycling bin 1. The platform 11 supports the liquefied gas cylinder. The recycling bin 1 is rectangular, and the platform 11 is located in the middle. The platform 11 is supported by the support springs 12, which push the platform 11 out of the recycling bin 1 (e.g., ...). Figure 2 The upper surface of the placement platform 11 is arc-shaped. When the liquefied gas cylinder is placed on the placement platform 11, the outer wall of the liquefied gas cylinder fits against the protrusions at both ends of the placement platform 11, and the weight of the liquefied gas cylinder presses down the placement platform 11, so that the liquefied gas cylinder is located in the recycling box 1, which makes it convenient to clean the cylinder. Scraping device 2 is set on the surface of the placement platform 11 and can move back and forth along the placement platform 11 to clean the stains on the outer wall of the liquefied gas tank. The scraping device 2 is attached to the outer wall of the tank and moves back and forth along the outer wall of the tank to scrape off the stains on the outer wall of the tank. The switching device 3 is set on the placement platform 11 and is used to drive the liquefied gas tank on the placement platform 11 to rotate. The rotation of the switching device 3 drives the tank to rotate on the placement platform 11, so that different sides of the tank come into contact with the scraping device 2, thereby achieving a comprehensive cleaning of the tank. The cleaning device 4 is installed inside the recycling bin 1 and is located on both sides of the placement platform 11. It is used to rotate and clean the outer wall of the liquefied gas tank. The rotation direction of the cleaning device 4 is opposite to that of the liquefied gas tank. When the placement platform 11 drives the tank into the recycling bin 1, it will cause the cleaning device 4 to fit against the tank and remove the oil stains on the outer wall of the tank.

[0020] In the specific implementation process, such as Figure 6 and Figure 7 As shown, the scraping device 2 includes a positive scraper 22 and a reciprocating screw 24. Two round rods 21 are fixedly installed in the middle groove of the placement platform 11. The two ends of the positive scraper 22 are slidably connected to the round rods 21. A sliding rod 25 is fixedly installed on the lower surface of the positive scraper 22. The reciprocating screw 24 is rotatably installed in the middle of the groove of the placement platform 11. The reciprocating screw 24 is connected to the sliding rod 25. The end of the reciprocating lead screw 24 is connected to the output end of the motor. The motor drives the reciprocating lead screw 24 to rotate. The reciprocating lead screw 24 drives the positive scraper 22 to move through the slide bar 25 (the reciprocating lead screw 24 and the slide bar 25 are parts in the prior art). The positive scraper 22 slides back and forth along the placement platform 11 through the round rod 21. The positive scraper 22 is in contact with the outer wall of the liquefied gas tank. The positive scraper 22 scrapes away the stains on the tank. Moreover, since the liquefied gas tank is cylindrical, when the liquefied gas tank is deformed or cracked, the positive scraper 22 will cause the tank to move differently when it moves along the tank. By observing the abnormal movements of the tank during cleaning, it is possible to determine whether the tank is damaged.

[0021] In the specific implementation process, such as Figure 6 and Figure 7 As shown, the scraping device 2 also includes a striking component 23 and a corrugated bar 234. The striking component 23 includes a spring block 231, which is slidably disposed in the groove of the positive scraper 22. Two lifting rods 232 are fixedly disposed on the lower surface of the spring block 231, and the lower ends of the two lifting rods 232 pass through the positive scraper 22. The corrugated bar 234 is fixedly installed in the groove of the placement platform 11, and the lower ends of the lifting rods 232 are in contact with the corrugations of the corrugated bar 234. Two limiting springs 233 are fixedly disposed in the groove of the positive scraper 22, and one end of the limiting spring 233 is fixedly connected to the lower surface of the spring block 231. The spring block 231 is located in the groove of the positive scraper 22 and can only move vertically along the inner wall of the groove of the positive scraper 22. When the positive scraper 22 moves, the positive scraper 22 drives the spring block 231 and the lifting rod 232 to move synchronously. When the lifting rod 232 moves along the corrugated strip 234, the lifting rod 232 will drive the spring block 231 to move up and down, so that the spring block 231 rises and contacts the outer wall of the liquefied gas tank. After the spring block 231 contacts the tank, it will make a sound. The sound can be used to judge whether the outer wall of the liquefied gas tank is damaged or corroded. The lifting rod 232 is equipped with a limit spring 233, which keeps the lower end of the lifting rod 232 in contact with the corrugated strip 234.

[0022] In the specific implementation process, such as Figure 4 and Figure 8 As shown, the switching device 3 includes a drive shaft 31, which is rotatably mounted inside the placement platform 11. Two drive wheels 32 are fixedly mounted on the drive shaft 31, and the drive wheels 32 are in contact with the outer wall of the liquefied gas tank on the placement platform 11. The rotation of the drive shaft 31 will drive the two drive wheels 32 to rotate. The rubber on the outer wall of the drive wheel 32 is in contact with the outer wall of the liquefied gas tank. The drive wheel 32 drives the tank to rotate through friction, causing the position of the tank to change, which makes it easier to scrape off and clean the stains on the tank.

[0023] In the specific implementation process, such as Figure 2 and Figure 3 As shown, the cleaning device 4 includes a cleaning brush 42, and movable blocks 41 are slidably provided in the grooves at both ends of the recycling bin 1. Both ends of the central shaft of the cleaning brush 42 are rotatably connected to the movable blocks 41. The ends of the cleaning brush 42 are all connected to the output end of the motor. The motor drives the cleaning brush 42 to rotate. The cleaning brush 42 has the same shape as the liquefied gas tank and is composed of cylindrical brushes. The brushes clean the oil stains on the outer wall of the tank. The moving block 41 can drive the cleaning brush 42 to move laterally along the inside of the recycling box 1, so as to get closer to and away from the liquefied gas tank. By observing the contact area between the cleaning brush 42 and the tank, it is also possible to judge whether the tank is damaged.

[0024] In the specific implementation process, such as Figure 4 and Figure 5As shown, the cleaning device 4 also includes a connecting assembly 44, which includes two base plates 441. The two base plates 441 are symmetrically installed at the bottom of the recycling bin 1. Two pairs of first toothed plates 443 and second toothed plates 444 are slidably provided on each of the two base plates 441. Gears 446 are rotatably provided on the upper surface of each of the two base plates 441. A gear 446 meshes between each of the first toothed plates 443 and the second toothed plates 444. A rectangular rod 445 is fixedly provided on one side of each of the second toothed plates 444. The upper end of each of the rectangular rods 445 is fixedly connected to the moving block 41. A rotating rod 442 is rotatably provided on each of the first toothed plates 443. The upper end of the rotating rod 442 is rotatably connected to the lower surface of the placement platform 11. After the placement platform 11 is pressed into the recycling box 1 by the liquefied gas tank, the placement platform 11 drives the first toothed plate 443 to slide laterally along the base plate 441 via the rotating rod 442. The first toothed plate 443 meshes with the gear 446, and when it moves, it drives the gear 446 to rotate. The gear 446 drives the second toothed plate 444 to move in the other direction. The second toothed plate 444 drives the moving block 41 to move via the rectangular rod 445. The moving block 41 then drives the cleaning brush 42 to move. This allows the placement platform 11 to descend and drive the cleaning brush 42 to move towards the center, and the placement platform 11 to rise and drive the cleaning brush 42 to move to both sides. When the cleaning brush 42 moves towards the center and comes into contact with the liquefied gas tank, it cleans the oil stains on the outer wall of the tank. When the cleaning brush 42 moves outward, it can be used for subsequent operations.

[0025] In the specific implementation process, such as Figure 2 and Figure 3 As shown, the cleaning device 4 also includes a removal component 43, which includes two fence frames 431. Both fence frames 431 are fixed inside the recycling bin 1. Both fence frames 431 are located on one side of the cleaning brush 42. Both fence frames 431 are fixed with a water spray pipe 432 at their upper ends. The nozzles on the water spray pipe 432 are located in the gaps between the fence frames 431. A control valve 433 is rotatably provided at one end of the water spray pipe 432. A torsion spring 434 is provided between the control valve 433 and the water spray pipe 432. When the moving block 41 moves the cleaning brush 42 outward, it passes through the gaps between the fence frames 431. The fence frames 431 are comb-shaped and function similarly to a comb, brushing away impurities attached to the cleaning brush 42. When the cleaning brush 42 passes through the fence frames 431, the moving block 41 contacts the control valve 433, causing the control valve 433 to rotate. The control valve 433 opens, allowing the water spray pipe 432 to spray water downwards to clean the cleaning brush 42, thus improving the cleaning efficiency of the cleaning brush 42 on the liquefied gas tank. Water pipe 432 is connected to an external delivery pipe and contains cleaning agent to remove oil stains from cleaning brush 42. By controlling the water flow rate of water spray pipe 432, the cleaning brush 42, which passes through quickly, is completely wetted by the cleaning water. When moving block 41 moves a certain distance, control valve 433 disengages from moving block 41 and is reset by torsion spring 434, and water spray pipe 432 stops spraying water. When cleaning brush 42 moves to the center, it will pass through fence frame 431 again and be cleaned again.

[0026] In the specific implementation process, such as Figure 2 and Figure 8 As shown, an intermittent assembly 5 is provided between the scraping device 2 and the switching device 3. The intermittent assembly 5 includes a first turntable 51 and a second turntable 53. The first turntable 51 is fixedly connected to the end of the reciprocating screw 24, and the second turntable 53 is fixedly connected to the end of the drive shaft 31. A drive rod 52 is fixedly provided on one side of the first turntable 51, and four drive slots 54 are symmetrically opened on the second turntable 53. When the motor drives the reciprocating screw 24 to rotate one revolution, the reciprocating screw 24 drives the first turntable 51 to rotate synchronously. The shaft on the drive rod 52 on the first turntable 51 will enter the drive groove 54 of the second turntable 53. The drive rod 52 moves along the drive groove 54, which will drive the second turntable 53 to rotate. The second turntable 53 rotates one-quarter revolution, and the second turntable 53 drives the drive shaft 31 to rotate, thereby driving the drive wheel 32. The drive wheel 32 drives the liquefied gas tank to rotate, so that the other surfaces of the tank body come into contact with the front scraper 22. The front scraper 22 covers one-quarter of the tank body. By rotating the tank body, the tank body is cleaned in all directions. Moreover, the direction of rotation of the tank body is opposite to that of the cleaning brush 42, which effectively removes oil stains from the outer wall of the tank body.

[0027] In the specific implementation process, such as Figure 1 As shown, an oil-water separator 6 is fixedly installed at the lower end of the recycling bin 1; the cleaning water mixed with oil and impurities will fall into the oil-water separator 6 to purify the wastewater. The oil-water separator 6 is a device in the prior art.

[0028] In the specific implementation process, such as Figure 4 and Figure 6As shown, side scrapers 26 are fixed on both sides of the upper surface of the placement platform 11. The side scrapers 26 are in contact with the outer wall of the liquefied gas tank placed on the placement platform 11. When the drive wheel 32 drives the liquefied gas tank to rotate, the outer wall of the liquefied gas tank contacts the side scrapers 26. The side scrapers 26 scrape away the dirt on the outer wall of the tank, thereby improving the cleaning efficiency of the tank.

[0029] It should be noted that, in order to facilitate the movement of the entire device, casters are provided at the bottom of the oil-water separator 6, and the casters are equipped with a self-locking device to fix the entire device when it is moved to the designated position.

[0030] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
