Description

Technical Field

[0001] This application relates to the technical field of waste shell recycling, and particularly to a shell emptying and cleaning system. Background Art

[0002] After the shell is loaded with gunpowder, if it is not fired for a long time, it needs to be scrapped. During the scrapping process, the gunpowder in the shell needs to be emptied. Emptying the gunpowder means taking out the gunpowder from the barrel and processing and recycling it.

[0003] As described in the background art of the invention patent with the authorization announcement number CN110685818B, currently, in China, the hot melting method is mainly used for manual emptying of gunpowder, that is, by heating to melt the gunpowder so that the gunpowder detaches from the barrel to achieve emptying.

[0004] However, this method makes the gunpowder in a high-temperature environment. The chemical properties of the gunpowder are unstable in a high-temperature environment, and there may be a situation of combustion and explosion, with great potential safety hazards. Moreover, for some large shells, the workload of manual emptying is very large, the duration is long, the potential safety hazards are further increased, and the emptying efficiency is also low. Summary of the Invention

Detailed implementation manners

[0041] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the following clearly and completely describes the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts also belong to the scope of protection of the present application.

[0042] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present application.

[0043] The terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, unless otherwise specified, the meaning of "plurality" is two or more.

[0044] In the description of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0045] First, some terms are explained as follows:

[0046] Cavitation refers to the process of the formation, development and collapse of vapor or gas cavities (voids) inside the liquid or at the liquid-solid interface when the local pressure in the liquid decreases.

[0047] An electric cylinder is a modular product that integrates a servo motor and a lead screw, converting the rotational motion of the servo motor into a linear motion. At the same time, it transforms the best advantages of the servo motor - precise rotational speed control, precise revolution control, and precise torque control - into - precise speed control, precise position control, and precise thrust control. It is a brand-new revolutionary product for realizing high-precision linear motion series.

[0048] The hollow rotary table is a new type of speed reducer product. Its turntable is of a hollow structure, and the servo motor is connected to the side, facilitating the installation of air pipes and electric wires in the jig. The turntable is supported by a set of precision crossed roller bearings. The rollers in the bearings are arranged staggeredly at 90 degrees, and the diameter of the rollers is slightly larger than the size of the raceway between the inner and outer rings of the bearing, so that there is a preload between the inner and outer rings of the crossed roller bearing and the rollers. Thus, the turntable of the servo rotary platform supported by the bearing can withstand various torques such as radial, axial, and overturning torques, and its rigidity is more than 10 times that of traditional bearings.

[0049] The hollow liquid-electric rotary joint is a hollow rotary joint, which is a sealed rotary connector that can rotate 360° to convey media (liquids and electricity). The non-rotating liquids and electricity can be rotationally conveyed through the liquid-electric rotary joint.

Figure 7 It is the three-dimensional structure schematic diagram of the winding and unwinding device used in the shell emptying and cleaning system provided by an embodiment of this application.

[0051] An embodiment of this application provides a shell emptying and cleaning system, as Figure 1 and Figure 2 shown, including a water storage tank 100, a cleaning water tank 200, a cavitation device 300, a circulating filtration device 400, and a control system. Among them, the water storage tank 100 is a container for storing water, the cleaning water tank 200 is a container for emptying and cleaning the shells, the cavitation device 300 can generate cavitation jets to empty the shells, and the circulating filtration device 400 can filter the solid-liquid mixture of the fallen ammunition and water to obtain ammunition and clean water.

[0052] As Figure 1 and Figure 2 shown, the water storage tank 100 is generally in a cuboid structure and contains clean water inside to provide clean water for the entire system.

[0053] As Figure 1 and Figure 2As shown, the cleaning water tank 200 is also generally in a cuboid structure. The upper end of the cleaning water tank 200 is open, and the shell can be put into the cleaning water tank 200 through the opening. The water inlet end of the cleaning water tank 200 is communicated with the water storage tank 100 through the first pipeline 210. A first electromagnetic valve (not shown in the figure) is provided on the first pipeline 210. When the first electromagnetic valve is opened, the clean water in the water storage tank 100 can enter the cleaning water tank 200.

[0054] As Figure 3 and Figure 4 shown, the cleaning water tank 200 is provided with a fixing device 220. The fixing device 220 is used to fix the shell to be emptied of medicine. The fixing device 220 fixes the shell horizontally, which is convenient for subsequent medicine emptying.

[0055] In specific implementation, the maximum size of the cleaning water tank 200 can be: 8200mm×2400mm×3000mm (length×width×height), which can meet the medicine emptying requirements of shells with a length less than 8000mm and a diameter less than 2400mm. Of course, the specific size of the cleaning water tank 200 can be adjusted according to the actual situation and is not limited here.

[0056] As Figure 5 and Figure 6 shown, the cavitation device 300 includes a cavitation component 310 and a first electric cylinder 320. The first electric cylinder 320 is generally fixed on the ground through a support frame. The cavitation component 310 is arranged on the telescopic rod of the first electric cylinder 320. The barrel opening of the cylinder barrel of the first electric cylinder 320 can be connected to the side wall of the cleaning water tank 200, so that the telescopic rod of the first electric cylinder 320 can extend into the cleaning water tank 200 and be coaxial with the barrel of the shell. Therefore, when the telescopic rod of the first electric cylinder 320 extends and retracts, it can drive the cavitation component 310 to move along the axial direction of the barrel.

[0057] As Figure 5 and Figure 6 shown, the cavitation component 310 includes a cavitation pipeline 311 and a cavitation nozzle 312 arranged on the cavitation pipeline 311. The cavitation pipeline 311 is communicated with the water storage tank 100 through the second pipeline 330. A second electromagnetic valve (not shown in the figure) is provided on the second pipeline 330. The clean water enters the cavitation pipeline 311 to form a cavitation jet to empty the medicine of the shell. The ammunition falls off from the barrel and is washed out of the barrel under the action of the cavitation jet and falls to the bottom of the cleaning water tank 200.

[0058] As Figure 1 and Figure 2As shown, the water inlet end of the circulating filtration device 400 is connected to the bottom of the cleaning water tank 200 through the third pipeline 410. A water pump 420 is provided on the third pipeline 410. The water outlet end of the circulating filtration device 400 is connected to the storage water tank 100 through the fourth pipeline 430. A third solenoid valve (not shown in the figure) is provided on the fourth pipeline 430. When the water pump 420 is turned on, the solid-liquid mixture of the ammunition block and water can be pumped into the circulating filtration device 400. After filtration, ammunition and clean water are obtained. The clean water re-enters the storage water tank 100, and the ammunition remains in the circulating filtration device 400.

[0059] Generally, the circulating filtration device 400 is composed of multiple-stage filtration components. For example, it can be composed of four-stage filtration (1. quartz sand filtration 2. activated carbon filtration 3. precision filtration 4. ultrafiltration). The sizes of the ammunition blocks allowed to pass through these four-stage filtrations decrease in sequence, realizing the step-by-step filtration of the ammunition blocks and ultimately realizing the filtration of the solid-liquid mixture.

[0060] The first solenoid valve, the first electric cylinder 320, the second solenoid valve, the water pump 420, and the third solenoid valve are all electrically connected to the control system. By controlling each component through the control system, the automatic control of the medicine pouring and cleaning process is realized.

[0061] Of course, various sensors, monitoring instruments, etc. are also provided in the whole device to cooperate with the control system to realize automatic control. For example, a liquid level sensor and a temperature sensor can be set in the cleaning water tank 200 to realize the monitoring of the liquid level and temperature in the cleaning water tank 200, and transmit the monitored signals to the control system to realize automatic control.

[0062] During use, first lift the shell, put it into the cleaning water tank 200 from the upper end, and fix it through the fixing device 220. Then, the clean water in the storage water tank 100 enters the cleaning water tank 200 until the whole shell is submerged. Then, the cavitation component 310 and the first electric cylinder 320 start to work. The cavitation component 310 generates a cavitation jet to pour the medicine for the shell, and the cavitation component 310 moves along the axial direction of the gun barrel under the action of the first electric cylinder 320 to realize the medicine pouring. The ammunition blocks falling off from the gun barrel gather at the bottom of the cleaning water tank 200. When the water pump 420 is turned on, the solid-liquid mixture (ammunition block and water) is pumped into the circulating filtration device 400 for filtration to obtain ammunition and clean water. The clean water enters the storage water tank 100 and can be reused, and the ammunition can be processed subsequently. During the whole process, the control system can control each component to realize automatic medicine pouring.

[0063] Compared with the prior art, this shell medicine pouring and cleaning system realizes the medicine pouring for the shell through the cavitation jet method, avoiding manual hot melting medicine pouring, greatly improving the medicine pouring efficiency, reducing the medicine pouring time, and during the medicine pouring process, the shell is in a submerged state, greatly reducing the safety hazard, and also realizing the collection of ammunition and the recycling of clean water.

[0064] In some embodiments, Figure 1 , Figure 2 and Figure 7 As shown, the artillery shell pouring and cleaning system also includes a high-pressure pump unit 500 and a retracting device 600. The high-pressure pump unit 500 is arranged on the second pipe 330, that is, the high-pressure pump unit 500 is arranged between the water storage tank 100 and the cavitation pipe 311, and is connected through the second pipe 330. The clean water in the water storage tank 100 first enters the high-pressure pump unit 500 through the second pipe 330, becomes high-pressure water, and then enters the cavitation pipe 311, so that the cavitation jet finally ejected from the cavitation nozzle 312 is a high-pressure jet, which has a flushing effect on the ammunition, is more convenient for pouring, and improves the efficiency of pouring.

[0065] The portion of the second pipeline 330 between the high-pressure pump unit 500 and the cavitation pipeline 311 is a hose, which is connected to the cavitation pipeline 311. Figure 7 As shown, the retractable device 600 includes a bracket 610 and a load-bearing wheel 620 rotatably connected to the bracket 610, the load-bearing wheel 620 is driven by a retractable motor 630, and the hose is wound around the load-bearing wheel 620. The load-bearing wheel 620 is outside the cleaning water tank 200, and the cavitation pipe 311 is inside the cleaning water tank 200. The hose can enter the cleaning water tank 200 from the upper end opening of the cleaning water tank 200 and connect with the cavitation pipe 311. Since the cavitation assembly 310 moves along the axial direction of the shell with the extension and contraction of the first electric cylinder 320, the hose should also be retractable. By winding the hose around the load-bearing wheel 620, the hose can be released and retracted, the structure is more reasonable, the hose is more neat, and there will be no problems such as knotting. The high-pressure pump unit 500 and the retractable motor 630 are both electrically connected to the control system. When the control system controls the extension and retraction of the first electric cylinder 320, the retractable motor 630 is controlled at the same time to realize the release and retraction of the hose.

[0066] It should be noted that the hose also has a certain hardness. Although it can be wrapped around the load-bearing wheel 620, it will not be flattened. In other words, high-pressure water can still pass through the hose to achieve high-pressure water transportation.

[0067] In some embodiments, Figure 1 and Figure 2As shown, the shell emptying and cleaning system further includes a chiller 700. The chiller 700 is connected to the water storage tank 100 through a fifth pipeline 710 and to the cleaning tank 200 through a sixth pipeline 720. A fourth solenoid valve (not shown in the figure) is provided on the fifth pipeline 710, and a fifth solenoid valve (not shown in the figure) is provided on the sixth pipeline 720. The chiller 700, the fourth solenoid valve, and the fifth solenoid valve are all electrically connected to the control system. When emptying the medicine, due to impacts and other effects, the water temperature in the cleaning tank 200 will rise. Therefore, the water temperature in the cleaning tank 200 is adjusted by the chiller 700 to keep the water temperature at a set safe temperature. For example, the safe temperature can be set to 40 degrees. The temperature sensor in the cleaning tank 200 monitors the temperature and transmits the signal to the control system. The control system can selectively turn on or off the chiller 700 according to the temperature in the cleaning tank 200. In this way, the water temperature in the cleaning tank 200 can be maintained below the safe temperature to ensure safe medicine emptying.

[0068] In addition, a liquid level sensor is also provided in the cleaning tank 200. The control system can, according to the signal of the liquid level sensor, control the first solenoid valve, the second solenoid valve, the water pump 420, and the chiller 700 to achieve a basic balance between the water inlet and outlet of the cleaning tank 200, so that the liquid level in the cleaning tank 200 remains dynamically balanced within a certain range, and the shell can always be completely submerged.

[0069] In some embodiments, as Figure 3 and Figure 4 shown, the fixing device 220 includes a frame 221, a support beam 222, a clamping block 223, and a support block 224. The frame 221 is similar in shape to the cleaning tank 200 and is generally in a cuboid structure. The frame 221 covers the cleaning tank 200. A second electric cylinder 225 and a guide rail 226 are provided on the frame 221. The second electric cylinder 225 is installed on the long side of the top surface of the frame 221, and the guide rail 226 is installed on the short side of the top surface of the frame 221.

[0070] The telescopic rod of the second electric cylinder 225 extends and retracts in the width direction of the cleaning tank 200. The guide rail 226 extends in the width direction of the cleaning tank 200. The support beam 222 extends in the length direction of the cleaning tank 200. The support beam 222 is slidably connected to the guide rail 226 and is connected to the telescopic rod of the second electric cylinder 225, so that the support beam 222 can slide along the guide rail 226 (the width direction of the cleaning tank 200) under the action of the second electric cylinder 225.

[0071] A third electric cylinder 227 is provided on the support beam 222. The telescopic rod of the third electric cylinder 227 extends and retracts in the vertical direction. The clamping block 223 is connected to the lower end of the telescopic rod of the third electric cylinder 227. The support block 224 is arranged in the cleaning water tank 200. The clamping block 223 can be lifted and lowered under the action of the third electric cylinder 227, and together with the support block 224, it realizes the clamping and fixing of the shell. Both the second electric cylinder 225 and the third electric cylinder 227 are electrically connected to the control system, and the opening and closing of the second electric cylinder 225 and the third electric cylinder 227 are controlled through the control system.

[0072] During specific use, the support beam 222 is moved to the edge of the frame 221, and the shell can be put in and taken out. After the shell is put in, the support beam 222 is moved above the shell, and then the clamping block 223 is lowered to the upper surface of the shell to realize clamping and fixing with the support block 224.

[0073] In some embodiments, as Figure 3 shown, the number of the second electric cylinders 225 is two, the number of the third electric cylinders 227 is three, and the number of the support blocks 224 is three, and they are all spaced along the length direction of the cleaning water tank 200. The support beam 222 is more evenly stressed and moves more smoothly. Fixing is carried out from different positions of the shell, and the fixing is more firm.

[0074] As Figure 4 shown, both the clamping block 223 and the support block 224 are provided with V-shaped grooves. The V-shaped groove of the clamping block 223 has a lower opening, and the V-shaped groove of the support block 224 has an upper opening. The clamping of the shell is realized through the V-shaped grooves, which can adapt to shells of different diameters and improve the adaptability of the whole product.

[0075] In some embodiments, as Figure 4 shown, a plurality of cushion blocks 228 are provided below the support block 224 to change the support height of the support block 224 by increasing or decreasing the cushion blocks 228. The height of the first electric cylinder 320 is fixed. When the shell is fixed, it should be coaxial with the telescopic rod of the first electric cylinder 320. Therefore, the support heights of shells with different diameters should be different, and the change of the support height can be realized by increasing or decreasing the cushion blocks 228. The structure is simple and convenient to adjust.

[0076] In some embodiments, as Figure 3 shown, a medicine storage groove 230 is formed at the bottom of the cleaning water tank 200. The medicine storage groove 230 can be located at one end of the cleaning water tank 200. The fallen ammunition will gradually gather in the medicine storage groove 230. The third pipeline 410 is connected to the bottom of the medicine storage groove 230, which is more convenient to pump out the ammunition.

[0077] In some embodiments, as Figure 5 and Figure 6As shown, the cavitation component 310 further includes a mounting plate 313 and a cavitation water guide plate 314. There are multiple cavitation pipes 311 and multiple cavitation nozzles 312. The mounting plate 313 is oppositely arranged on the telescopic rod of the first electric cylinder 320 and can move along the axial direction of the shell with the telescopic rod of the first electric cylinder 320.

[0078] Multiple cavitation pipes 311 are installed on the mounting plate 313 and are evenly distributed circumferentially around the telescopic rod of the first electric cylinder 320. The cavitation water guide plate 314 is provided with a water channel. The cavitation water guide plate 314 is arranged at one end of the cavitation pipe 311 away from the mounting plate 313. That is to say, the mounting plate 313 and the cavitation water guide plate 314 are respectively located at both ends of the multiple cavitation pipes 311, and both the cavitation pipes 311 and the water channel are filled with water.

[0079] Multiple cavitation nozzles 312 are arranged on the cavitation pipes 311 and the cavitation water guide plate 314. Of course, the cavitation nozzles 312 need to be connected to the cavitation pipes 311 and the water channel so that water can enter the cavitation nozzles 312 and be ejected. The water forms a cavitation jet in the cavitation nozzles 312. After the cavitation jet is ejected, it reaches the ammunition on the inner wall of the gun barrel and collapses, generating an impact on the ammunition.

[0080] The cavitation nozzles 312 spray towards the inner wall of the gun barrel of the shell and the side of the cavitation water guide plate 314 away from the mounting plate 313. That is to say, the cavitation jet is sprayed towards the ammunition on the inner wall of the gun barrel and the ammunition on the side of the cavitation water guide plate 314 away from the mounting plate 313. As the ammunition is stripped, the cavitation component 310 is moved along the axial direction of the gun barrel by the first electric cylinder 320, gradually penetrating deeper into the gun barrel, so that all the ammunition in the gun barrel can be stripped.

[0081] In some embodiments, as Figure 5 shown, the cavitation component 310 further includes a hollow rotating platform 315 and a hollow liquid-electric rotating joint 316. The fixed part of the hollow rotating platform 315 is coaxially fixed with the telescopic rod of the first electric cylinder 320. The rotating part of the hollow rotating platform 315 is coaxially fixed with the mounting plate 313. The fixed part of the hollow liquid-electric rotating joint 316 is coaxially fixed with the fixed part of the hollow rotating platform 315. The rotating part of the hollow liquid-electric rotating joint 316 is coaxially fixed with the mounting plate 313. The hollow rotating platform 315 is electrically connected to the control system. When the rotating part of the hollow rotating platform 315 rotates, it can drive the rotating part of the hollow liquid-electric rotating joint 316 and the mounting plate 313 to rotate together, realizing the rotary transmission of liquid and electricity.

[0082] It should be noted that the hollow rotating platform 315 and the hollow liquid-electric rotating joint 316 are off-the-shelf products and are generally customized according to actual needs. In actual use, the hollow rotating platform 315 can be selected from the DASEN brand, and the hollow liquid-electric rotating joint 316 can be selected from the Senrui Pu or Moflon brand.

[0083] In some embodiments, as Figure 5 and Figure 6 shown, a plurality of connecting rods 3131 are hinged to the edge of the mounting plate 313. The number of the plurality of connecting rods 3131 is equal to the number of the cavitation pipes 311. The first ends of the plurality of cavitation pipes 311 are respectively and correspondingly hinged to the ends of the connecting rods 3131 far away from the mounting plate 313, and the second ends of the plurality of cavitation pipes 311 are hinged to the cavitation guide water plate 314. In this way, the relative position (relative angle) between the cavitation pipes 311 and the cavitation guide water plate 314 can be changed to adapt to shells of different diameters.

[0084] A rotary motor 3141 is provided at the center of the cavitation guide water plate 314. The rotary motor 3141 is drivingly connected with a lead screw 3142. A nut 3132 is provided at the center of the mounting plate 313. The nut 3132 is matched with the lead screw 3142. The rotary motor 3141 is electrically connected with the control system. Since the mounting plate 313 is fixed, when the rotary motor 3141 is started, the lead screw 3142 rotates together with the rotary motor 3141. Under the action of the nut 3132, the lead screw 3142 moves along the axial direction of the mounting plate 313, thereby driving the cavitation guide water plate 314 to approach or move away from the mounting plate 313. The relative angle between the cavitation pipes 311 and the cavitation guide water plate 314 changes accordingly, that is, the inclination angle of the cavitation pipes 311 is changed, and the coverage range that the cavitation nozzles 312 on the cavitation pipes 311 can cover is changed to adapt to gun barrels of different diameters.

[0085] In this case, both the hollow rotary platform 315 and the hollow liquid-electric rotary joint 316 are of hollow structures and will not affect the movement of the lead screw 3142. Moreover, a cylindrical mounting structure can be formed on the side of the mounting plate 313 close to the hollow rotary platform 315, which is convenient for connecting the mounting plate 313 with the hollow rotary platform 315 and the hollow liquid-electric rotary joint 316.

[0086] It should be noted that the gun barrel is generally generally cylindrical, and there are generally neckings at both ends of the gun barrel, so that the diameters at both ends of the gun barrel are variable. The cavitation assembly 310 with such a structure is also more suitable for pouring medicine at both ends of the gun barrel.

[0087] During use, the water delivery pipe and the electric wire are connected into the fixed part of the hollow liquid-electric rotary joint 316, so that water and electricity are led out from the rotary part of the hollow liquid-electric rotary joint 316, and then the water is communicated with the cavitation pipes 311 and the cavitation guide water plate 314 through a pipe, and the electricity is communicated with the rotary motor 3141 through an electric wire, so that the pipes and electric wires in this part can rotate together with the rotary part of the hollow liquid-electric rotary joint 316 and the mounting plate 313, avoiding the problem of winding of the pipes and electric wires.

[0088] In some embodiments, the protection grades of the housings of the rotary motor 3141 and the motor of the hollow rotary platform 315 are both IP68. Since the rotary motor 3141 and the hollow rotary platform 315 are both inside the cleaning water tank 200 and operate in water and are completely submerged in water, water ingress should be avoided to ensure the normal operation of the motors. The higher the value of the protection grade, the better the protection performance. The first digit is for dust protection, and grade 6 represents complete prevention of dust ingress, which is the highest grade. The second digit is for water protection, and grade 8 represents prevention of water ingress when submerged, that is, even when submerged in water, water ingress can be prevented, and grade 8 is the highest grade.

[0089] For large artillery shells, the length is relatively long, up to several meters. Therefore, in some embodiments, the first electric cylinder 320 is a multi-stage electric cylinder, and the stroke of each stage is 1000 mm. The multi-stage electric cylinders extend and retract sequentially, and the strokes are superimposed sequentially to meet the requirement of pouring medicine for large artillery shells. For example, the number of stages of the first electric cylinder 320 can be 6, and the maximum stroke is 6 m, meeting the requirement of pouring medicine for a 6 m long artillery shell.

[0090] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
