Description

Technical Field

[0001] This invention belongs to the technical field of spray gun rinsing equipment, specifically an automatic rinsing device for spray guns used in the production of powdered emulsion explosives. Background Technology

[0002] Emulsion explosives are a type of water-in-oil emulsion explosive that uses an emulsifier to uniformly disperse droplets of an oxidizing agent salt solution in a continuous oil-phase medium containing porous materials such as dispersed air bubbles or hollow glass microspheres. Developed in the 1970s, emulsion explosives are a type of water-containing explosive. The production process of powdered emulsion explosives employs spray powdering technology, which requires the use of a spray gun. Typically, the spray gun must be rinsed before and after production.

[0003] In existing automatic cleaning devices for spray guns used in the production of powdered emulsion explosives, the spray gun is usually fixed in a cleaning tank and its surface is cleaned using a side nozzle. During cleaning, water is supplied from the inside by inserting an insertion tube into the spray hole of the spray gun. However, the spray gun has a relatively complex structure, making it difficult to fix in place. After fixing, it is inconvenient to insert the insertion tube. The difficulty in fixing and the inconvenience of internal water supply result in poor actual performance.

[0004] Furthermore, in the existing automatic cleaning device for spray guns used in the production of powdered emulsion explosives, the spray gun is fixed inside the cleaning tank and then sprayed on the surface through the external water pipe. However, the fixed spray gun still needs to be connected to the insertion pipe for internal water supply cleaning, which makes it difficult for the fixed spray gun to rotate. As a result, the fixed water pipe on the side sprays water from a fixed angle, resulting in a relatively limited cleaning area on the surface of the spray gun and ineffective cleaning of some areas, leading to poor actual surface cleaning effect. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic cleaning device for spray guns used in the production of powdered emulsion explosives, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic rinsing device for spray guns used in the production of powdered emulsion explosives, comprising a base, a support rod fixedly connected to the top surface of the base, a fixing plate fixedly connected to the top surface of the support rod, a water tank fixedly sleeved on the top surface of the fixing plate, a fixing pipe fixedly connected to the bottom surface of the water tank, an insertion tube movably sleeved on the inner surface of the fixing pipe, an installation groove formed on the outer surface of the insertion tube, an elastic airbag fixedly sleeved on the inner surface of the installation groove, and a first limiting ring and a second limiting ring respectively fixedly sleeved on the outer surface of the insertion tube. The first and second limiting rings are located below and above the elastic airbag, respectively. Both the first and second limiting rings are fixedly connected to the side of the elastic airbag. A distribution mechanism is fixedly sleeved on the outer surface of the fixed tube. A control tube is movably sleeved on the top surface of the second limiting ring. The lower end of the control tube passes through the second limiting ring and the elastic airbag and is sleeved inside the first limiting ring. A side opening is provided on the outer surface of the control tube. The lower end of the distribution mechanism is movably sleeved with the control tube. A side plate is fixedly connected to the side of the fixed plate. An air pump is fixedly installed on the bottom surface of the side plate. An air pipe is fixedly connected between the bottom surface of the air pump and the distribution mechanism.

[0007] First embodiment: as follows Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, during cleaning, align the spray nozzle of the spray gun with the insertion tube, ensuring the insertion tube fits into the nozzle. Simultaneously, ensure the first and second limiting rings are positioned within the spray nozzle. Start the air pump, which then introduces air through the air pipe into the inner cavity of the distribution mechanism. The air in the inner cavity flows through the curved pipe to the sleeve. The gas in the sleeve then flows through the control pipe and its side opening to the elastic air bladder, causing the elastic air bladder to inflate and expand, filling the spray nozzle and clamping the spray gun securely. After securing the nozzle, high pressure is then introduced into the water tank. The water flow causes high-pressure water to enter the insertion tube through the fixed tube and then into the spray gun for internal cleaning. After the internal cleaning of the spray gun is completed, the water supply is stopped and the electromagnet in the distribution mechanism is turned off, causing the electromagnet to lose its magnetism and thus disengaging the control tube from the electromagnet. With the continuous supply of air, the gas pushes the control tube downward to the top surface of the limit plate. At this time, the side opening on the side of the control tube moves to below the first limit ring. With the continuous air supply from the air pump, the gas enters the interior of the spray gun through the control tube, causing the continuously supplied air to dry the interior of the spray gun.

[0008] First, by creating an installation groove on the outer surface of the insertion tube and fixing an elastic airbag within it, and then fixing a distribution mechanism on the outer surface of the fixing tube, during cleaning, the insertion tube and elastic airbag are inserted into the nozzle of the spray gun. An air pump then introduces air into the elastic airbag, causing it to inflate and expand within the nozzle, thus sealing the nozzle. Simultaneously, the outward expansion force clamps the spray gun from the inside, making clamping convenient and simple to operate. Furthermore, the position of the control tube is adjusted using an electromagnet in the distribution mechanism, changing the final airflow direction of the air pump and achieving post-cleaning air drying. This effectively reduces the number of additional air pumps required, avoiding the need for multiple sets of power air pumps, resulting in better performance.

[0009] Furthermore, by adding a sleeve to the bottom of the distribution mechanism and an electromagnet to the side of the sleeve, the control tube is stably attracted and fixed when the inner end of the electromagnet is energized. This allows gas to be introduced into the elastic airbag for expansion and clamping. After cleaning, the electromagnet is disconnected, causing the control tube to lose its magnetic effect and move downward, changing the position of the side opening. This allows the original clamping power air to be introduced into the spray gun, achieving rapid air drying after cleaning. The actual switching process is quick and easy to operate, achieving automatic rinsing and drying, greatly improving the cleaning efficiency of the spray gun and resulting in good performance.

[0010] Preferably, the dispensing mechanism includes a mounting ring, an inner cavity, a movable ring, a curved tube, a sleeve, and an electromagnet. The mounting ring is fixedly sleeved on the outer surface of the fixed tube, the inner cavity is formed on the outer surface of the mounting ring, the movable ring is movably sleeved inside the inner cavity, the curved tube is fixedly connected to the side of the movable ring, the sleeve is fixedly connected to the bottom surface of the curved tube, and the electromagnet is fixedly installed on the side of the sleeve. By utilizing the strong magnetism of the electromagnet when energized, the control tube is attracted and fixed, and when the power is off, the control tube falls due to gravity, thereby realizing the up and down control of the control tube.

[0011] Preferably, the control tube is movably sleeved inside the sleeve, the side opening is located inside the elastic airbag, and the bottom surface of the first limiting ring has a sleeve hole. The inner surface of the sleeve hole is movably sleeved with the control tube. By controlling the up and down movement of the control tube, the position of the side opening can be controlled, thereby changing the actual air ejection direction. The airbag expands and clamps in time within the elastic airbag. When it is below the first limiting ring, the air inside the spray gun is dried by air force, making it convenient to use.

[0012] Preferably, a telescopic rod is fixedly installed on the top surface of the base, and a cleaning box is fixedly connected to the top surface of the telescopic rod. A power mechanism is provided on the bottom surface of the cleaning box, and a rotating plate is provided on the top of the power mechanism. The cleaning box can be moved up and down by using the telescopic rod, ensuring that there is enough space at the top before it is raised to facilitate operations such as connecting and fixing the spray gun, thereby improving practicality and convenience.

[0013] Preferably, the top surface of the rotating plate is provided with a sleeve groove, the inner surface of the sleeve groove is fixedly connected with a magnetic plate, the outer surface of the cleaning box is fixedly sleeved with a water spray pipe, and the outer side of the water spray pipe is fixedly connected with a water inlet pipe. By using the water spray pipe to spray cleaning water from the outside, the outside of the spray gun is cleaned. The cleaning box moves to the outside of the spray gun to ensure that the cleaning water will not splash.

[0014] Preferably, the power mechanism includes a mounting frame, a motor, and a rotating shaft. The mounting frame is fixedly connected to the bottom surface of the cleaning tank, the motor is fixedly installed inside the mounting frame, and the rotating shaft is fixedly connected to the output shaft of the motor. By utilizing the rotation of the motor in the power mechanism, the rotating plate is rotated, which drives the spray gun to rotate and tilt outward.

[0015] Preferably, a connecting rod is fixedly connected to the bottom surface of the first limiting ring. The connecting rod is located outside the sleeve hole, and a limiting plate is fixedly connected to the bottom surface of the connecting rod. By using the limiting plate to restrict the movement of the control tube, the control tube is prevented from falling out.

[0016] Preferably, a retaining ring is fixedly sleeved on the inner surface of the fixed tube, and an annular groove is formed on the outer surface of the insertion tube. The inner surface of the annular groove is movably sleeved with the retaining ring. By utilizing the movable sleeved connection between the retaining ring and the annular groove, the insertion tube has a stable rotation effect, ensuring that the fixed spray gun can rotate to clean the outer side.

[0017] Preferably, the lower end of the air tube is fixedly connected to the top surface of the mounting ring, and the air tube is connected to the inner cavity. By using the air tube to be fixedly connected to the mounting ring from the top, the curved tube is prevented from colliding with the air tube during rotation, thus ensuring a stable rotation effect.

[0018] Second embodiment: as follows Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8 As shown, when the spray gun is clamped in place, activate the telescopic rod to move the cleaning box upwards, positioning it outside the spray gun. This causes the magnetic plate on the top of the rotating plate to adhere to the bottom of the spray gun. Activate the power mechanism to rotate the magnetically attached spray gun, while simultaneously introducing external cleaning water into the inlet pipe. This external cleaning water is then sprayed onto the rotating spray gun through the spray pipe, quickly cleaning its surface. After cleaning, the cleaning water is drained, and the air pump is turned off. The spray gun automatically falls onto the top of the rotating plate, and the cleaned spray gun can then be removed.

[0019] First, by fixing a retaining ring to the inner surface of the fixed tube and inserting it into an annular groove on the outer surface of the tube, the inserted tube is kept rotating. The spray gun is then clamped and fixed from the inside by the expansion of an elastic airbag, so that the spray gun can still rotate after being fitted and fixed at the insertion tube. The magnetic plate on the top surface of the rotating plate is used to attract the bottom of the spray gun, so that the rotating plate drives the spray gun to rotate stably, avoiding the inability to rotate under stable fixation. With the addition of a water spray pipe on the side, the internal cleaning of the spray gun can be completed simultaneously with the external cleaning, which improves the actual cleaning uniformity and greatly improves the cleaning efficiency of the spray gun.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. This invention utilizes an installation groove on the outer surface of an insertion tube, in which an elastic airbag is fixedly fitted. A distribution mechanism is also fixed on the outer surface of a fixed tube. During cleaning, the insertion tube and elastic airbag are inserted into the nozzle of a spray gun, and air is pumped into the elastic airbag using an air pump. This causes the elastic airbag to inflate and expand within the nozzle, sealing the nozzle. Simultaneously, the outward expansion force clamps and secures the spray gun from the inside. The clamping is convenient and the operation is simple. Furthermore, the position of the control tube is adjusted using an electromagnet in the distribution mechanism, thereby changing the final airflow direction of the air pump. This also enables air drying after cleaning, effectively reducing the number of additional air pumps required and avoiding the need for multiple sets of power air pumps. The result is excellent performance.

[0022] 2. This invention adds a sleeve to the bottom of the distribution mechanism and an electromagnet to the side of the sleeve. When the inner end of the electromagnet is energized, the control tube is stably attracted and fixed, allowing gas to be introduced into the elastic airbag for expansion and clamping. After cleaning, the electromagnet is disconnected, causing the control tube to lose its magnetic effect and move downward, changing the position of the side opening. This allows the original clamping air to be introduced into the spray gun, achieving rapid air drying after cleaning. The actual switching process is rapid and the operation is simple, achieving automatic rinsing and drying, greatly improving the cleaning efficiency of the spray gun and providing good results.

[0023] 3. This invention uses a retaining ring fixed to the inner surface of a fixed tube and an annular groove on the outer surface of the inserted tube to keep the inserted tube rotating. An elastic airbag expands to clamp and fix the spray gun from the inside, ensuring the spray gun continues to rotate even after being fitted and fixed at the inserted tube. A magnetic plate on the top surface of the rotating plate attracts the bottom of the spray gun, allowing the rotating plate to drive the spray gun to rotate stably, preventing it from being unable to rotate under stable fixation. Combined with a water spray pipe added to the side, this allows for simultaneous internal and external cleaning of the spray gun, improving the uniformity of actual cleaning and significantly increasing the cleaning efficiency of the spray gun.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] like Figures 1 to 8As shown, this embodiment of the invention provides an automatic rinsing device for spray guns used in the production of powdered emulsion explosives. It includes a base 1, a support rod 2 fixedly connected to the top surface of the base 1, a fixing plate 3 fixedly connected to the top surface of the support rod 2, a water tank 4 fixedly sleeved on the top surface of the fixing plate 3, a fixing pipe 5 fixedly connected to the bottom surface of the water tank 4, an insertion pipe 6 movably sleeved on the inner surface of the fixing pipe 5, an installation groove 7 formed on the outer surface of the insertion pipe 6, an elastic airbag 10 fixedly sleeved on the inner surface of the installation groove 7, and a first limiting ring 8 and a second limiting ring 9 fixedly sleeved on the outer surface of the insertion pipe 6. The first limiting ring 8 and the second limiting ring 9 are respectively located at the elastic airbag 10. Below and above 0, the first limiting ring 8 and the second limiting ring 9 are fixedly connected to the side of the elastic airbag 10. The outer surface of the fixed tube 5 is fixedly sleeved with the distribution mechanism 14. The top surface of the second limiting ring 9 is movably sleeved with the control tube 11. The lower end of the control tube 11 passes through the second limiting ring 9 and the elastic airbag 10 and is sleeved inside the first limiting ring 8. The outer surface of the control tube 11 has a side opening 12. The lower end of the distribution mechanism 14 is movably sleeved with the control tube 11. The side of the fixed plate 3 is fixedly connected with the side plate 15. The bottom surface of the side plate 15 is fixedly installed with the air pump 16. The bottom surface of the air pump 16 is fixedly connected to the distribution mechanism 14 with an air pipe 17.

[0035] First embodiment: as follows Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, during cleaning, align the nozzle of the spray gun with the insertion tube 6, and insert the insertion tube 6 into the nozzle. Simultaneously, ensure that the first limiting ring 8 and the second limiting ring 9 are positioned within the nozzle of the spray gun. Start the air pump 16. The air pump 16 introduces air through the air pipe 17 into the inner cavity 142 of the distribution mechanism 14. The air in the inner cavity 142 flows through the curved pipe 144 to the sleeve 145. The gas in the sleeve 145 flows through the control pipe 11 and the side opening 12 on the side of the control pipe 11 to the elastic airbag 10, causing the elastic airbag 10 to inflate and expand, thus filling the nozzle of the spray gun. This clamps and secures the spray gun, completing the fixation process, and then supplies water to the water tank 4. High-pressure water is introduced, allowing it to pass through the fixed pipe 5 into the insertion pipe 6, and then into the spray gun for internal cleaning. Once the internal cleaning of the spray gun is complete, the water supply is stopped, and the electromagnet 146 in the distribution mechanism 14 is turned off, causing the electromagnet 146 to lose its magnetism. This allows the control pipe 11 to detach from the electromagnet 146. As air is continuously supplied, the gas pushes the control pipe 11 downwards to the top surface of the limiting plate 29. At this time, the side opening 12 on the side of the control pipe 11 moves to below the first limiting ring 8. As the air pump 16 continuously supplies air, the gas passes through the control pipe 11 into the interior of the spray gun, causing the continuously supplied air to dry the interior of the spray gun.

[0036] First, by creating an installation groove 7 on the outer surface of the insertion tube 6 and fixing the elastic airbag 10 in the installation groove 7, and fixing the distribution mechanism 14 on the outer surface of the fixing tube 5, during cleaning, the insertion tube 6 and the elastic airbag 10 are inserted into the nozzle of the spray gun, and the air pump 16 is used to introduce air into the elastic airbag 10, causing the elastic airbag 10 to inflate and expand in the nozzle of the spray gun, thereby sealing the nozzle of the spray gun. At the same time, the outward expansion force is used to clamp and fix the spray gun from the inside, which is convenient and easy to operate. In addition, the position of the control tube 11 is adjusted by the electromagnet 146 in the distribution mechanism 14, thereby changing the final jet direction of the air pump 16, and achieving air drying after cleaning. This reduces the number of additional air pumps used, avoids the installation of multiple sets of power air pumps, and has a good effect.

[0037] Furthermore, by adding a sleeve 145 to the bottom surface of the distribution mechanism 14 and an electromagnet 146 to the side of the sleeve, the control tube 11 is stably attracted and fixed when the inner end of the electromagnet 146 is energized, so that gas can be introduced into the elastic airbag 10 for expansion and clamping. After cleaning, by disconnecting the electromagnet 146, the control tube 11 loses its magnetic effect and moves downward, changing the position of the side opening 12, thereby introducing the original clamping power air into the spray gun, achieving rapid air drying after cleaning. The actual switching process is rapid and the operation is simple, realizing automatic rinsing and air drying, which greatly improves the cleaning efficiency of the spray gun and has a good effect.

[0038] The distribution mechanism 14 includes a mounting ring 141, an inner cavity 142, a movable ring 143, a curved tube 144, a sleeve 145, and an electromagnet 146. The mounting ring 141 is fixedly sleeved on the outer surface of the fixed tube 5. The inner cavity 142 is opened on the outer surface of the mounting ring 141. The movable ring 143 is movably sleeved inside the inner cavity 142. The curved tube 144 is fixedly connected to the side of the movable ring 143. The sleeve 145 is fixedly connected to the bottom surface of the curved tube 144. The electromagnet 146 is fixedly installed on the side of the sleeve 145. By using the strong magnetism of the electromagnet 146 when it is energized, the control tube 11 is attracted and fixed. When the power is off, the control tube 11 falls due to gravity, thereby realizing the up and down control of the control tube 11.

[0039] The control tube 11 is movably sleeved inside the sleeve 145, and the side opening 12 is located inside the elastic airbag 10. The bottom surface of the first limiting ring 8 is provided with a sleeve hole 13, and the inner surface of the sleeve hole 13 is movably sleeved with the control tube 11. By controlling the up and down movement of the control tube 11, the position of the side opening 12 is controlled, thereby changing the actual air ejection direction. The airbag expands and clamps in the elastic airbag 10 over time. When it is below the first limiting ring 8, the air inside the spray gun is dried by air force, making it convenient to use.

[0040] The base 1 has a telescopic rod 18 fixedly installed on its top surface. The top surface of the telescopic rod 18 is fixedly connected to a cleaning box 19. The bottom surface of the cleaning box 19 is provided with a power mechanism 20. The top of the power mechanism 20 is provided with a rotating plate 21. The cleaning box 19 can be moved up and down by using the telescopic rod 18, ensuring that there is enough space at the top before it is raised to facilitate operations such as attaching and fixing the spray gun, thus improving its practicality and convenience.

[0041] The rotating plate 21 has a socket groove 22 on its top surface. A magnetic plate 23 is fixedly connected to the inner surface of the socket groove 22. A water spray pipe 24 is fixedly sleeved on the outer surface of the cleaning box 19. A water inlet pipe 25 is fixedly connected to the outer side of the water spray pipe 24. The outside of the spray gun is cleaned by spraying cleaning water from the outside through the water spray pipe 24. The cleaning box 19 moves to the outside of the spray gun to ensure that the cleaning water will not splash.

[0042] The power mechanism 20 includes a mounting frame 201, a motor 202, and a rotating shaft 203. The mounting frame 201 is fixedly connected to the bottom surface of the cleaning tank 19. The motor 202 is fixedly installed inside the mounting frame 201. The rotating shaft 203 is fixedly connected to the output shaft of the motor 202. By rotating the motor 202 in the power mechanism 20, the rotating plate 21 is rotated, which drives the spray gun to rotate and tilt outward.

[0043] Among them, the bottom surface of the first limiting ring 8 is fixedly connected to the connecting rod 28, the connecting rod 28 is located outside the sleeve hole 13, and the bottom surface of the connecting rod 28 is fixedly connected to the limiting plate 29. By using the limiting plate 29 to restrict the movement position of the control tube 11, the control tube 11 is prevented from falling out.

[0044] The inner surface of the fixed tube 5 is fixedly sleeved with a retaining ring 27, and the outer surface of the insertion tube 6 is provided with an annular groove 26. The inner surface of the annular groove 26 is movably sleeved with the retaining ring 27. By using the retaining ring 27 to movably sleeve the annular groove 26, the insertion tube 6 has a stable rotation effect, ensuring that the fixed spray gun can rotate to clean the outer side.

[0045] The lower end of the air tube 17 is fixedly connected to the top surface of the mounting ring 141. The air tube 17 is connected to the inner cavity 142. By using the air tube 17 to be fixedly connected to the mounting ring 141 from the top, the curved tube 144 is prevented from colliding with the air tube 17 during rotation, thus ensuring a stable rotation effect.

[0046] Second embodiment: as follows Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8As shown, when the spray gun is fixed and clamped, the telescopic rod 18 is activated, causing the telescopic rod 18 to move the cleaning box 19 upward, so that the cleaning box 19 is located outside the spray gun, and the magnetic plate 23 on the top surface of the rotating plate 21 is attracted to the bottom of the spray gun. The power mechanism 20 is activated, causing the rotating plate 21 to rotate the magnetically attracted spray gun. At the same time, external cleaning water is introduced into the water inlet pipe 25. The external cleaning water is sprayed onto the rotating spray gun through the water spray pipe 24, so that the surface of the spray gun is quickly cleaned. After cleaning, the cleaning water is discharged, and the air pump 16 is turned off. The spray gun automatically falls on the top surface of the rotating plate 21, and the cleaned spray gun can be removed.

[0047] First, by fixing a retaining ring 27 to the inner surface of the fixed tube 5 and opening an annular groove 26 on the outer surface of the inserted tube 6, the inserted tube 6 is kept rotating. The spray gun is clamped and fixed from the inside by the expansion of the elastic airbag 10, so that the spray gun still has a rotating effect after being sleeved and fixed at the inserted tube 6. The magnetic plate 23 on the top surface of the rotating plate is used to make the bottom of the spray gun attracted by the rising magnetic plate, so that the rotating plate 21 drives the spray gun to rotate stably, avoiding the inability to rotate under stable fixation. With the addition of the water spray pipe 24 on the side, the internal cleaning of the spray gun is completed while the external cleaning is completed, which improves the actual cleaning uniformity and greatly improves the cleaning efficiency of the spray gun.
