Description

Technical Field

[0001] The present invention relates to the technical field of explosive production, and particularly to an explosive transfer and temporary storage system that can achieve top-sealed feeding, hopper-sealed movement, and bottom-sealed discharging. Background Art

[0002] In the field of ammunition production, especially in the pressing production of large explosive charges, it is often necessary to transfer and test explosives. During the transfer process, materials often spill or fall outside the hopper to become floating explosives, which will become potential safety hazards and are also not conducive to the occupational health of employees, especially in the transfer process of powder materials.

[0003] In the prior art, for large-scale explosive transfer, explosive packaging barrels are usually placed on small trolleys manually, pushed manually to the place where materials are needed, and the materials are poured manually.

[0004] The method of manually pouring and transferring materials has the following disadvantages:

[0005] 1. The pouring process is not safe and is prone to accidents, resulting in the dropping of the packaging barrel, the materials not being poured into the designated container, and spilling outside, thus triggering dangerous accidents such as explosions.

[0006] 2. During the pouring process, materials are likely to leak outside the equipment to form floating explosives, which are not easy to clean.

[0007] 3. The dust formed by spilling during the pouring process inhaled by employees will endanger the physical health of workers.

[0008] 4. Manual transfer has a high labor intensity and is prone to production fatigue, thus endangering physical health.

[0009] To realize the automatic pressing production of large explosive charges, it is necessary to solve the automatic control of the explosive transfer process. When the explosives are automatically transferred and circulated, how to achieve the sealed transfer of explosives and control the floating explosives generated during the transfer process has become a key research direction in the ammunition industry.

[0010] Therefore, how to achieve the sealed transfer of explosives and control the floating explosives generated during the transfer process is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0011] In view of the above problems, the present invention provides an explosive transfer and temporary storage system for overcoming the above problems or at least partially solving the above problems. This system is used to achieve the automatic transfer of heavy explosives and realizes the sealed transfer of powdered explosives by means of top-sealed feeding, hopper-sealed movement, and bottom-sealed discharging.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention belong to the scope of protection of the present invention.

[0037] See Figure 1 、 Figure 2 、 Figure 3 , a kind of explosive transfer and temporary storage system provided by the embodiments of the present invention. As shown in Figure 1 、 Figure 2 、 Figure 3 , the system may include:

[0038] The feeding docking unit 1, the feeding docking unit 1 includes a first lifting drive assembly 11, a feeding docking pipe 12 and a feeding jacking assembly 13. The feeding jacking assembly 13 is located inside the feeding docking pipe 12 and is connected to the lower end of the feeding docking pipe 12. The upper end of the feeding docking pipe 12 is used to be connected to a material packaging barrel;

[0039] The transfer unit 2, the transfer unit 2 includes a transfer hopper 21, a feeding channel 22, an upper sealing cover 23, a conical surface feeding switch valve 24 and a funnel sealing cone assembly 25. The upper sealing cover 23 is connected to the top of the transfer hopper 21 to seal the top of the transfer hopper 21. The feeding channel 22 is connected to the upper sealing cover 23 and is communicated with the inside of the transfer hopper 21. The conical surface feeding switch valve 24 is located in the feeding channel 22 and is connected to the upper sealing cover 23 through a switch valve reset assembly 26. The funnel sealing cone assembly 25 includes a hopper sealing cone 251, a guide rod 252 and a second lifting drive assembly (not shown in the figure). The hopper sealing cone 251 is located inside the transfer hopper 21. The second lifting drive assembly is connected to the upper sealing cover 23. The first end of the guide rod 252 passes through the upper sealing cover 23 and is connected to the hopper sealing cone 251. The second end of the guide rod 252 is connected to the second lifting drive assembly;

[0040] Wherein, the first lifting drive assembly 11 is used to drive the feeding docking pipe 12 to move up and down to switch between a first low position and a first high position. In the first low position, the feeding jacking assembly 13 contacts the conical surface feeding switch valve 24 and drives the conical surface feeding switch valve 24 to move downward, so that a gap is formed between the conical surface feeding switch valve 24 and the feeding channel 22. In the first high position, the feeding jacking assembly 13 is separated from the conical surface feeding switch valve 24, so that the conical surface feeding switch valve 24 closes the feeding channel 22 under the action of the switch valve reset assembly 26;

[0041] The second lifting drive assembly is used to drive the hopper sealing cone 251 to move up and down to switch between the second low position and the second high position. In the second low position, the hopper sealing cone 251 closes the discharge port of the transfer hopper 21. In the second high position, the hopper sealing cone 251 is separated from the transfer hopper 21 to form a gap between the hopper sealing cone 251 and the discharge port of the transfer hopper 21.

[0042] In the explosive transfer and temporary storage system provided by the embodiment of the present application, multiple sealing methods are used. When it is not necessary to add explosives into the transfer hopper 21 or during the transfer process, the transfer hopper 21 adopts sealing methods such as an upper cover sealing method and a spindle guide shaft sealing method, etc., so that a sealed environment can be formed inside the transfer hopper 21. A breathing valve can be installed on the upper cover to ensure the pressure balance inside and outside the hopper through the breathing valve, and filter the dust generated during the material transfer process.

[0043] When it is necessary to add explosives into the transfer hopper 21, the feeding docking unit 1 can be connected to the material packaging barrel. The feeding docking pipe 12 can move up and down under the drive of the first lifting drive assembly 11. The feeding jacking assembly 13 can open the conical surface feeding switch valve 24, so that a gap is formed in the feeding channel 22. When the switch of the material packaging barrel is opened, the explosives can enter the transfer hopper 21 through this gap. At the same time, it can ensure the sealed connection at the connection between the feeding channel 22 and the feeding docking pipe 12.

[0044] In addition, after the transfer unit 2 is transferred to the discharging position and it is necessary to transfer the explosives outwards, only by lifting the funnel sealing cone through the second lifting drive assembly, the explosives inside the transfer hopper 21 can flow out from the gap between the discharging port of the transfer hopper 21 and the funnel sealing cone. Thus, the sealed operation of the whole process of adding medicine, transferring and discharging medicine is realized.

[0045] In order to ensure that the feeding jacking assembly 13 can smoothly open the conical surface feeding switch valve 24 during the descending process, the embodiment of the present application can also provide that the feeding jacking assembly 13 includes a groove adapted to the tip of the cone of the conical surface feeding switch valve 24. This groove can be opposite to the tip of the cone of the conical surface feeding switch valve 24 in the vertical position. As the feeding jacking assembly 13 descends, the tip can enter the groove, and the feeding jacking assembly 13 continues to descend to open the conical surface feeding switch valve 24. After the explosive addition is completed, the conical surface feeding switch valve 24 is separated from the feeding jacking assembly 13. The switch valve reset assembly 26 can be in the form of a tension spring. After losing the downward pressure, the switch valve reset assembly 26 can pull the conical surface feeding switch valve 24 upwards to reset it and block the feeding channel 22.

[0046] The upper sealing cover 23 provided by the embodiment of the present application can be arranged on the top of the transfer hopper 21 in a flat layer to block the top of the transfer hopper 21. To ensure that when cleaning and other operations need to be carried out inside the transfer hopper 21, it is convenient to remove the upper sealing cover 23, the embodiment of the present application can also provide that the upper sealing cover 23 is connected to the top of the transfer hopper 21 through a detachable locking component.

[0047] To prevent material leakage at the connection between the guide rod 252 and the upper sealing cover 23, the embodiment of the present application can also provide that the upper sealing cover 23 is provided with a guide copper sleeve 253, and the second end of the guide rod 252 passes through the guide copper sleeve 253 and is connected to the second lifting drive assembly. Further, a sealing ring 254 is provided between the guide copper sleeve 253 and the guide rod 252.

[0048] When the hopper sealing cone 251 provided by the embodiment of the present application is in the low position, it can close the discharge port of the transfer hopper 21. To further improve the closing effect, the embodiment of the present application can also provide that the hopper sealing cone 251 is provided with a conical sealing rubber pad 255 extending along its circumferential direction.

[0049] To ensure that when transferring explosives from the transfer hopper 21 to other storage devices in the system provided by the embodiment of the present application, leakage does not occur at the connection, the embodiment of the present application can also provide a blanking docking unit 3, and the blanking docking unit 3 includes a blanking funnel assembly and a third lifting drive assembly 31; a blanking flange 211 is provided at the lower end of the transfer hopper 21; the third lifting drive assembly 31 is used to drive the blanking funnel assembly to move up and down and switch between a third low position and a third high position;

[0050] In the third low position state, the blanking funnel assembly is separated from the transfer hopper 21, and in the third high position state, the blanking flange 211 extends into the interior of the blanking funnel assembly to make the blanking funnel assembly and the transfer hopper 21 be sealed and connected.

[0051] To further improve the sealing performance of the connection between the blanking funnel assembly and the transfer hopper 21, the embodiment of the present application can also provide that the top of the blanking funnel assembly is provided with a blanking sealing rubber pad 32.

[0052] The blanking funnel assembly provided by the embodiment of the present application can move upward under the drive of the third lifting drive assembly 31. To facilitate the drive, the embodiment of the present application can also provide that the blanking funnel assembly includes a fixed funnel 34 and a lifting funnel 35 connected by an electrostatic conductive hose 33, and the lifting funnel 35 is connected to the third lifting drive assembly 31; the blanking sealing rubber pad 32 is connected to the top of the lifting funnel 35.

[0053] To ensure that the residual explosives in the blanking funnel assembly do not leak when there is no need to transfer explosives to other storage devices, the embodiment of the present application can also provide a cover plate 36, which is arranged on the upper part of the blanking funnel assembly and connected to the rotary drive assembly 37; the rotary drive assembly 37 is used to drive the cover plate 36 to rotate so as to open or close the upper part of the blanking funnel assembly.

[0054] The following details the specific usage method and principle of the system provided by the embodiment of the present application. The sealing methods of the explosive transfer and temporary storage system provided by the embodiment of the present application are divided into three types: feed docking seal, static seal during transportation, and blanking docking seal.

[0055] Static seal during transportation:

[0056] First, the upper sealing cover 23 and the transfer hopper 21 are compacted by a detachable locking assembly 27, and at the same time, sealant is used for sealing between them; the guide copper sleeve 253 is installed on the upper sealing cover 23, and sealing rings 254 are installed at both ends of the guide copper sleeve 253 to ensure that explosives do not diffuse out of the hopper through the installation position of the guide copper sleeve 253. The upper sealing cover 23 is also designed with a feed sealing mechanism composed of a conical surface feed switch valve 24 and a switch valve reset assembly 26. During the sealed transportation process, the conical surface feed switch valve 24 is pressed against the feed channel 22 of the upper sealing cover 23 upward under the action of the switch valve reset assembly 26, and is sealed through the conical surface, ensuring that no impurities enter the hopper interior through this channel after the feeding is completed, and also preventing the diffusion of explosive dust through this channel.

[0057] A blanking channel is designed at the lower end of the funnel. This channel is sealed by the zero-contact installation of a sealing ring 254 on the hopper sealing cone 251 and the transfer hopper 21. This sealing structure initially relies on the gravity of the hopper sealing cone 251, and subsequently relies on the acting force of the material on the sealing cone for sealing, which can achieve the function that the heavier the material, the better the sealing effect. Thus, the hopper forms a sealed hopper, and only the filter valve installed on the upper sealing cover 23 is used to keep the internal and external pressures unified.

[0058] Feed docking seal:

[0059] The transfer hopper 21 is installed on the first floor. Materials are transferred from the second floor to the transfer barrel and then transported to the hopper of the required equipment through the transfer barrel. When materials need to be transferred into the transfer hopper 21, the material packaging barrel moves to the second-floor feeding position. Under the action of the first lifting drive assembly 11 (linear cylinder), the feeding docking pipe 12 extends upward and downward to dock between the material packaging barrel and the transfer hopper 21. At the lower end of the downward tip of the feeding docking pipe 12, a feeding jacking assembly 13 is designed, which can jack the conical feeding switch valve 24 downward to open the feeding channel 22. The front end of the feeding docking pipe 12 is designed as a cone, which penetrates and fits the feeding channel 22 on the upper sealing cover 23 to form a sealed material pipeline. Then, the feeding valve of the material packaging barrel is opened, and the materials are hermetically transported to the transfer hopper 21 through the feeding docking pipe 12 and the feeding channel 22. At this time, relying on the dual actions of the gravity of the materials and its own weight, the hopper sealing cone 251 gets closer and closer to the lower end of the transfer hopper 21 to complete the sealing of the feeding port and prevent the spillage of the powder.

[0060] Feeding docking seal:

[0061] When the transfer funnel reaches the specified position and needs to be transferred to other storage equipment, the cover plate 36 rotates 180 degrees under the action of the rotation drive assembly 37 (rotary cylinder) to expose the lifting funnel 35 equipped with the static conductive hose 33. The lifting funnel 35 is equipped with a sealing gasket. Under the action of the third lifting drive assembly 31 (linear cylinder), the sealing gasket tightly fits the flange surface of the feeding port of the transfer hopper 21 to form a sealed feeding channel. At this time, under the drive of the second lifting drive assembly (linear cylinder), the lifting conical hammer guide rod 252 moves upward in the guide sleeve, creating a feeding gap between the hopper sealing cone 251 and the transfer hopper 21, and the materials can be transferred to other places through the feeding sealing channel.

[0062] In summary, for the explosive transfer and temporary storage system provided in this application, only manual pushing of the packaging barrel containing materials to the specified position is required throughout the process, and the rest of the actions are completed by the equipment itself, reducing the labor intensity of workers. The entire process of explosive transfer is carried out in a sealed state, effectively reducing the occurrence of floating explosives. It can achieve the isolated transfer of dangerous goods such as explosives, reducing the contact between personnel and explosives and avoiding potential hazards brought by behaviors such as pouring agents during the transfer process.
