[0002] In industries such as pharmaceuticals and chemicals, it is often necessary to transfer energetic solid materials (flammable and explosive) to the next process. The production environment in these processes typically requires F0 or F1 zones, rendering conventional transfer equipment unusable. Currently, manual transfer is the most common method. Manual transfer not only suffers from high labor intensity and low efficiency, but also exposes workers to dust and pungent odors that can negatively impact their health. Furthermore, the flammability and explosiveness of energetic solid materials pose certain safety hazards. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a simple structure, high degree of automation, good reliability, and beneficial to reducing labor intensity and improving efficiency for a tipping and unloading device for flammable and explosive materials.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A tipping and unloading device for flammable and explosive materials includes a frame, a tipping support mounted on the frame, and a hopper located below the tipping support. The tipping support is provided with a guide, a positioning component for fixing a material carrier to the guide, and a discharge hopper for docking with the material carrier. The guide is located in a water tank, which has a drain outlet and a water inlet. A collection component is located below the drain outlet, and a discharge valve is located at the outlet of the discharge hopper.

[0006] As a further improvement to the above technical solution: the positioning component includes a positioning seat on the flipping bracket, a positioning cylinder on the positioning seat, and a positioning block connected to the piston rod of the positioning cylinder, wherein the positioning block is provided with at least one positioning slot.

[0007] As a further improvement to the above technical solution: a guide structure is provided between the positioning seat and the positioning block.

[0008] As a further improvement to the above technical solution: the positioning cylinder is arranged in a vertical direction.

[0009] As a further improvement to the above technical solution: a hydraulic motor is provided on one side of the frame, and the hydraulic motor is connected to the tilting bracket through a drive shaft. A driven shaft is provided on the opposite side of the frame, and the driven shaft is connected to the tilting bracket.

[0010] As a further improvement to the above technical solution: an inflatable sealing ring is provided at the docking point between the unloading hopper and the material carrier.

[0011] As a further improvement to the above technical solution: the silo is provided with a feeding pipe, and the feeding pipe is provided with an inverted conical docking part for connecting with the outlet of the unloading hopper.

[0015] Compared with the prior art, the advantages of this utility model are:

[0016] This utility model discloses a tipping and unloading device for flammable and explosive materials. During operation, the material carrier moves along the guide on the tipping support until it accurately aligns with the upper unloading hopper. After the material carrier is in place, a positioning component fixes it to the guide to prevent movement during subsequent tipping. The tipping support then tilts downwards until the outlet of the unloading hopper aligns with the lower silo. At this point, the unloading valve opens, and the material in the material carrier passes through the unloading hopper into the silo. The device features a simple structure, high automation, and good reliability, reducing labor intensity and improving efficiency. The guide is located in a water tank, where water washes away dust adhering to it and keeps it moist, preventing the material carrier from squeezing out dust and reducing friction between the material carrier and the guide, thus significantly reducing the risk of explosion. When the tipping support tilts, water in the tank is drained through the drain outlet and collected by the collector below. When tipping and unloading is required again, water is refilled into the tank through the water inlet, and then the next material carrier moves along the guide to its position.

[0017] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Figures 1 to 5 This invention illustrates an embodiment of a tipping and unloading device for flammable and explosive materials. The device includes a frame 1, a tipping support 2 mounted on the frame 1, and a hopper 3 located below the tipping support 2. The tipping support 2 is equipped with a guide 21, a positioning component 5 for fixing a material carrier 4 to the guide 21, and a discharge hopper 6 for docking with the material carrier 4. The guide 21 is located in a water tank 22, which has a drain outlet 23 and a water inlet (not shown; for example, the water inlet 23 and drain outlet can be located at opposite ends of the water tank 22). A collection component 7 is located below the drain outlet 23, and a discharge valve 61 is located at the outlet of the discharge hopper 6. The guide 21 can be, for example, a guide rail or a guide groove; the material carrier 4 can be, for example, a medicine basket; the collection component 7 can be, for example, a collection tray or a collection hopper; and the discharge valve 61 is preferably a clamp valve.

[0030] This utility model discloses a tilting and unloading device for flammable and explosive materials. During operation, the material carrier 4 moves along the guide member 21 on the tilting support 2 until it accurately aligns with the upper unloading hopper 6. After the material carrier 4 is in place, the positioning component 5 fixes the material carrier 4 to the guide member 21 to prevent movement during subsequent tilting. Then, the tilting support 2 tilts downwards until the outlet of the unloading hopper 6 aligns with the lower hopper 3. At this point, the unloading valve 61 opens, and the material in the material carrier 4 passes through the unloading hopper 6 into the hopper 3. The device features a simple structure, high degree of automation, and good reliability, which helps reduce labor intensity and improve efficiency. See details... Figure 5 The guide component 21 is located in the water tank 22. The water in the water tank 22 can clean the dust adhering to the guide component 21 and keep the guide component 21 moist, thereby preventing the material carrier 4 from squeezing the dust and reducing the friction between the material carrier 4 and the guide component 21, thus significantly reducing the risk of explosion. When the tilting bracket 2 tilts, the water in the water tank 22 can be discharged through the drain outlet 23 and collected by the collection component 7 below. When it is necessary to tilt and unload again, after the tilting bracket 2 is reset, water can be refilled into the water tank 22 through the water inlet, and then the next material carrier 4 moves into position along the guide component 21.

[0031] See the figure for details. Figure 1 and Figure 2In this embodiment, the positioning component 5 includes a positioning seat 51 mounted on the flipping bracket 2, a positioning cylinder 52 mounted on the positioning seat 51, and a positioning block 53 connected to the piston rod of the positioning cylinder 52. The positioning block 53 has at least one positioning slot 54. After the material carrier 4 is in place, the piston rod of the positioning cylinder 52 extends, causing the positioning slot 54 on the positioning block 53 to engage the rollers 41 on the material carrier 4, thereby effectively restricting the movement of the material carrier 4 along the guide member 21. The structure is simple and reliable. Preferably, the specific number of positioning slots 54 is consistent with the number of rollers 41 on the material carrier 4, corresponding one-to-one to engage each roller 41. Compared to a motor, the positioning cylinder 52 is more suitable for energetic materials, which helps to prevent explosions.

[0032] In a preferred embodiment, a guide structure (not shown in the figure, such as a guide shaft on the positioning block 53 and a guide sleeve on the positioning seat 51, or a guide rail and a slider, etc.) is provided between the positioning seat 51 and the positioning block 53 to provide guidance for the movement of the positioning block 53 and prevent deviation.

[0033] In a preferred embodiment, the positioning cylinder 52 is arranged vertically, which can effectively utilize the space in the height direction of the flipping bracket 2 and reduce the volume of the flipping bracket 2. Of course, in other embodiments, the positioning cylinder 52 can also be arranged horizontally, which can also clamp the roller 41, but it will result in an increase in the width dimension of the flipping bracket 2.

[0034] See details Figure 2 In this embodiment, a hydraulic motor 11 is provided on one side of the frame 1. The hydraulic motor 11 is connected to the tilting bracket 2 via a drive shaft 12. A driven shaft 13 is provided on the opposite side of the frame 1, and the driven shaft 13 is connected to the tilting bracket 2. The drive shaft 12 and the driven shaft 13 can achieve stable installation of the tilting bracket 2 on the frame 1. The hydraulic motor 11 can drive the tilting bracket 2 to rotate in both directions via the drive shaft 12. Compared with an electric motor, the hydraulic motor 11 is more suitable for energetic materials, which helps to avoid explosions.

[0035] Furthermore, in this embodiment, an inflatable sealing ring (not shown in the figure) is provided at the docking point between the unloading hopper 6 and the material carrier 4. After the material carrier 4 reaches below the unloading hopper 6, the inflatable sealing ring inflates and expands, thereby effectively sealing the gap between the material carrier 4 and the unloading hopper 6, ensuring airtightness, and preventing material leakage.

[0036] See details Figure 4 In this embodiment, the hopper 3 is provided with a feeding pipe 31, and the feeding pipe 31 is provided with an inverted conical connecting part 32 for connecting with the outlet of the unloading hopper 6. The inverted conical connecting part 32 facilitates connection with the outlet of the unloading hopper 6, so that the material in the unloading hopper 6 can smoothly enter the feeding pipe 31. The structure is simple and effective.

[0037] Furthermore, in this embodiment, the feed pipe 31 is a telescopic pipe and equipped with a lifting drive cylinder 33, and the docking member 32 is a flexible docking member. After the material carrier 4 and the unloading hopper 6 are flipped, the lifting drive cylinder 33 drives the feed pipe 31 to rise, so that the docking member 32 is tightly connected with the outlet of the unloading hopper 6, which helps to prevent material leakage. The use of a flexible docking member is beneficial to improving sealing performance and preventing rigid collisions that could damage the unloading hopper 6 and the docking member 32. The feed pipe 31 can be an elastic pipe or a corrugated pipe to avoid hindering the lifting and lowering movement of the docking member 32. Compared with a motor, the lifting drive cylinder 33 is more suitable for energetic materials, which helps to avoid explosions.

[0038] Furthermore, in this embodiment, a conical guide 34 is provided below the inlet of the hopper 3, and the guide 34 is provided with multiple discharge holes 35. After the material passes through the inlet of the hopper 3, it can be guided to the surrounding area by the guide 34, while some material can continue to fall through the discharge holes 35. This helps to distribute the material evenly within the hopper 3 and slows down the descent speed of the material, thereby reducing friction and collision between materials. For energetic materials, this helps to reduce the risk of combustion and explosion.

[0039] Furthermore, in this embodiment, the hopper 3 is equipped with a static-conducting screen 36, and a flow guide 34 is disposed on the screen 36. The screen 36 serves two purposes: firstly, it reduces the falling speed of the material, thereby reducing friction and collision between the materials; secondly, it can also conduct static electricity generated by friction between the materials, preventing static electricity accumulation. For energetic materials, this can further reduce the risk of combustion and explosion.

[0040] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
