Description

Technical Field

[0001] This invention relates to the field of energetic materials technology, and in particular to a highly safe lifting device for transporting energetic materials. Background Technology

[0002] Energetic materials, as special launch energy sources for barrel-launched weapons, artillery-launched missiles, and various catapult devices, have wide applications in both defense and civilian fields. Equipment for conveying energetic material propellants is essential in the automated production process of energetic materials. However, because energetic material components are highly sensitive to different forms of energy stimulation, such as mechanical, thermal, and electrostatic stimuli, higher requirements are placed on the safety of energetic material particle conveying equipment.

[0003] Currently, conventional Z-type hoists have the following shortcomings when used for transporting energetic materials:

[0004] 1. When energetic material particles are added to the hopper, they may bounce onto the chain. As the chain moves, it may cause energy stimulation to the energetic material that bounces onto it, potentially leading to a safety accident.

[0005] 2. The friction between the chain and sprocket can generate heat, which may pose a safety hazard.

[0006] 3. If the hopper does not empty completely when discharging, some tablets will stick to the inner wall of the hopper, and some tablets will also stick to the outer wall of the hopper when the hopper is turned over during discharging.

[0007] 4. The hopper is inconvenient to clean.

[0008] 5. When the hopper transitions from the vertical lifting section to the horizontal outlet section, it is difficult to ensure that the coaxiality of all the relative hopper mounting pins on the actual chain meets the requirements. When the coaxiality deviation is large, the friction between the hopper and the hopper mounting pin is large, which makes the hopper unable to maintain horizontality under the action of gravity torque in the transition section, thus causing some tablets to be poured out of the hopper prematurely. Summary of the Invention

[0009] In view of the above problems, the present invention provides a lifting device for conveying energetic materials to overcome or at least partially solve the above problems. It solves the problem that conventional Z-type elevators cannot meet the conveying requirements of energetic material tablets.

[0051] To prevent the material hopper 3 from rotating at the transition point between the vertical lifting section 200 and the horizontal outlet section 300, causing pesticide spillage, this embodiment of the application may also provide a guide limiting strip 17 on the inner side of the vertical door 16; the guide limiting strip 17 is located at the transition point between the vertical lifting section 200 and the horizontal outlet section 300; the guide limiting strip 17 is used to block the edge of the material hopper 3 to prevent the material hopper 3 from rotating clockwise.

[0052] Furthermore, the guide limit strip 17 is made of bent steel strip, and the guide limit strip 17 includes an arc segment, the radius of which is 0-6 mm larger than the pitch circle radius of the sprocket included in the chain circuit 2.

[0053] The specific structure and usage of the device provided in the embodiments of this application will be described in detail below.

[0054] The lifting device for conveying energetic materials provided in the embodiments of this application, such as... Figure 1 As shown, the device includes an inlet horizontal section 100, a vertical lifting section 200, and an outlet horizontal section 300. The hopper 3 of the device discharges material in the horizontal section of the chain loop 2 at the lower part of the outlet horizontal section 300.

[0055] For ease of description, along the movement direction of chain loop 2, the transition section between the inlet horizontal section 100 and the vertical lifting section 200 is called transition section A, and the transition section between the vertical lifting section 200 and the outlet horizontal section 300 is called transition section B.

[0056] like Figures 1-9 As shown in the embodiments of this application, the lifting device for conveying energetic materials may include: an inlet horizontal section 100, a vertical lifting section 200, an outlet horizontal section 300, a vertical door 16, a guide limit bar 17, a first cleaning pipe 11, a second cleaning pipe 12, a first air blowing assembly 8, a first air blowing rigid pipe 81, a second air blowing assembly 9, a second air blowing rigid pipe 91, an air blowing hose 92, a water receiving box 7, a chain wetting pipe 6, an air blowing nozzle 10, a discharge hopper 18, a feed hopper 4, a guide bag 5, a conveying hopper 3, a third cleaning pipe 13, a fourth cleaning pipe 14, and a fifth cleaning pipe 15.

[0057] The assembly relationship of each component is as follows:

[0058] The guide bag 5 is installed on the feed hopper 4, which is installed on the housing 1 of the inlet horizontal section 100. When the conveying hopper 3 passes through the inlet horizontal section 100, the lower end of the guide bag 5 can contact the upper edge of the conveying hopper 3.

[0059] A set of chain wetting pipes 6 is installed above the chain at the horizontal section 100 of the entrance, and a water receiving box 7 is installed below the chain loop 2. The water receiving box 7 is equipped with a drain outlet, which can be connected to the sewer ditch through a plastic hose.

[0060] Another set of chain wetting pipes 6 is installed above the chain loop 2 at the outlet horizontal section 300, and a water receiving box 7 is installed below the chain loop 2. The water receiving box 7 is equipped with a drain outlet, which can be connected to the sewer ditch through a plastic hose.

[0061] The upper and lower sides of the hopper at the tipping point of the outlet horizontal section 300 are provided with a first cleaning pipe 11, a second cleaning pipe 12, a first air blowing assembly 8, and a second air blowing assembly 9; an air blowing nozzle 10 is provided above the water receiving box 7 near the second air blowing assembly 9; a third cleaning pipe 13, a fourth cleaning pipe 14, and a fifth cleaning pipe 15 are respectively provided at the inlet horizontal section 100, the vertical lifting section 200, and the outlet horizontal section 300.

[0062] The first air blowing assembly 8 is provided with 3 first rigid air blowing pipes 81, and the first rigid air blowing pipes 81 are made of ordinary PU air pipes.

[0063] The second air blowing assembly 9 is provided with two sets of air blowing pipes: one set is the second rigid air blowing pipes 91, which are distributed on both sides and used to blow off the tablets adhered near the inner walls on both sides of the hopper; the other set is the flexible air blowing pipes 92, which are distributed in the middle and used to purge the tablets adhered on the inner wall of the middle part of the hopper. The second rigid air blowing pipes 91 are made of ordinary PU air pipes, and will not swing significantly when compressed air at a certain pressure is passed therethrough; the flexible air blowing pipes 92 are made of relatively soft hoses (such as latex hoses) with a relatively long length. When compressed air at a certain pressure is passed therethrough, the flexible air blowing pipes 92 will swing significantly, so as to realize the purging action.

[0064] In specific implementation, each of the first cleaning pipe 11, the second cleaning pipe 12, the third cleaning pipe 13, the fourth cleaning pipe 14 and the fifth cleaning pipe 15 may be provided with a plurality of spray nozzles.

[0065] A guide limit strip 17 is arranged at the transition section between the vertical lifting section 200 and the outlet horizontal section 300. The guide limit strip 17 is mounted on the vertical door 16. The guide limit strip 17 is formed by bending a steel strip with a certain thickness, and has an arc segment in its structure. This is because the movement track of the left edge of the material conveying hopper 3 at the transition section B is an arc. Through calculation, the arc radius of the movement track is equal to the pitch circle radius r of the sprocket, so the relationship between the radius r' of the arc segment and the pitch circle radius r of the sprocket is r<r'≤r+6. Specifically, the arc segment is 1-6 mm away from the left edge of the material conveying hopper 3 at the transition section B.

[0066] The working process of the lifting device for energetic material conveying provided by the embodiments of the present application includes:

[0067] When the device is in operation, the chain loop 2 will be wetted under the action of the chain wetting pipe 6, and the water after wetting the chain loop 2 will flow into the two water receiving boxes 7 and then be discharged through the drain outlets on the water receiving boxes 7.

[0068] Energetic material granules are added into the material conveying hopper 3 through the feeding hopper 4 and the cloth bag. In this process, since the lower part of the cloth bag is in contact with the upper edge of the material conveying hopper 3, the energetic material granules will not jump out of the hopper.

[0069] When the material conveying hopper 3 is driven by the chain loop 2 to the transition section B, if the coaxiality deviation of the hopper mounting pins on the chain loop 2 is relatively large, the material conveying hopper 3 tends to rotate clockwise. At this time, due to the blocking effect of the guide limit strip 17 on the edge of the material conveying hopper 3, the material conveying hopper 3 can be ensured to remain substantially horizontal.

[0070] When the conveying hopper 3 is driven by the chain loop 2 to the unloading hopper 18 for unloading, most of the tablets will enter the unloading hopper 18 under gravity. A small number of tablets will remain on the inner wall of the hopper, and a small number of tablets will adhere to the outer wall of the conveying hopper 3 when the hopper is turned. At this time, the second blowing assembly 9 will blow off the tablets remaining on the inner wall of the hopper, while the first blowing assembly 8 will blow off the tablets remaining on the outer wall of the hopper. When the swinging blowing pipe of the second blowing assembly 9 blows the tablets in the hopper, the tablets may be blown into the water receiving box 7 located at the outlet horizontal section 300. To prevent the tablets from being blown into the water receiving box 7, a blowing nozzle 10 is installed above the water receiving box 7 at a position lower than the hopper. The airflow from the blowing nozzle 10 forms a barrier, which can effectively prevent the tablets from entering the water receiving box 7.

[0071] When the device needs to be cleaned, the hopper 3 continues to move with the chain. The first cleaning pipe 11 and the second cleaning pipe 12 can clean the hopper 3, while the third cleaning pipe 13, the fourth cleaning pipe 14 and the fifth cleaning pipe 15 can clean the inner wall of the device's housing.

[0072] In summary, the lifting device for conveying energetic materials provided in this application effectively prevents tablets from jumping out of the hopper during feeding, thus avoiding safety hazards; it also effectively avoids safety hazards caused by chain friction heat generation; it effectively solves the problem of tablets adhering to the hopper wall during hopper discharge; and it effectively prevents premature tipping of the hopper at the transition section between the vertical lifting section and the horizontal outlet section. The provided cleaning unit facilitates cleaning of the device. It is worthy of widespread adoption.
