Abstract
Description
Technical Field
[0001] This utility model relates to production equipment used in the pharmaceutical, chemical and other industries, and in particular to a transfer device for flammable and explosive materials. Background Technology
[0002] In industries such as pharmaceuticals and chemicals, materials undergoing drying typically require transfer within and outside the dryer, usually driven by motors using automated methods such as rolling or sliding. However, when the transferred material is energetic (flammable and explosive), the production environment must be zone F0 or F1. Traditional automated transfer methods, whether rolling or sliding, generate friction, leading to static electricity and compression, which can easily ignite energetic materials and cause safety accidents, thus failing to meet the requirements. Therefore, manual transfer is currently widely used. However, manual transfer is labor-intensive, inefficient due to the limited number of material carriers at a time, and the dust hazard to workers. Furthermore, energetic solid materials are flammable and explosive, posing a safety risk. 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 transfer device for flammable and explosive materials that is convenient for automatic transfer, has a simple structure, and good safety.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] A transfer device for flammable and explosive materials includes a transfer track and a material carrier that can move along the transfer track. The transfer track is disposed in a water tank. At least one end of the water tank is provided with a mounting base. The mounting base is provided with a water-stopping component that can float up and down. The water-stopping component is provided with at least one guide surface for guiding the material carrier to move onto or away from the transfer track.
[0006] As a further improvement to the above technical solution: the mounting base is provided with a mounting groove, and the mounting groove is provided with an elastic reset member, which is located below the water-stopping member.
[0007] As a further improvement to the above technical solution: a guide rod is provided in the mounting groove, and the elastic reset element is a helical spring and is sleeved on the guide rod.
[0008] As a further improvement to the above technical solution: the mounting base is provided with a water inlet on the side connected to the transfer track, the bottom of the mounting groove is provided with a drain outlet, the drain outlet is connected to a drain pipe, and the drain pipe is provided with a drain valve.
[0009] As a further improvement to the above technical solution: there is a gap between the water-stopping component and the water inlet.
[0010] As a further improvement to the above technical solution: the material of the water-stopping component is polytetrafluoroethylene.
[0011] As a further improvement to the above technical solution: a spray pipe is provided above the transfer track, and the spray pipe is provided with multiple spray sections.
[0012] As a further improvement to the above technical solution: the top surface of the transfer track is an upwardly convex arc surface.
[0013] As a further improvement to the above technical solution: the height of the vertex of the arc surface is lower than the height of the water tank.
[0014] As a further improvement to the above technical solution: the material carrier is provided with a rolling element, the shape of which is adapted to the transfer track.
[0015] Compared with the prior art, the advantages of this utility model are:
[0016] This utility model discloses a transfer device for flammable and explosive materials. The transfer track is placed in a water tank. The water in the tank wets and cleans the transfer track and the parts of the material carrier that come into contact with it, reducing static electricity and pressure caused by friction. This significantly reduces the risk of explosion when the material carrier moves along the transfer track, improving safety, facilitating automated transfer, and increasing transfer efficiency. At least one end of the water tank is equipped with a floating water-stop component with a guide surface. When the material carrier needs to move onto or leave the transfer track, the guide surface causes the water-stop component to sink, allowing it to pass smoothly and reducing friction and pressure between the material carrier and the water-stop component, thus lowering the risk of explosion. After the material carrier passes, the water-stop component floats up, reducing water overflow from the tank and keeping the transfer track submerged. The device has a simple structure and high reliability.
[0017] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0031] Figures 1 to 7 This illustration shows an embodiment of the present invention for a transfer device for flammable and explosive materials. The device includes a transfer track 1 and a material carrier 2 movable along the transfer track 1. The transfer track 1 is disposed in a water tank 3. At least one end of the water tank 3 is provided with a mounting base 4. The mounting base 4 is provided with a water-stopping component 41 that can float up and down. The water-stopping component 41 is provided with at least one guide surface 411 for guiding the material carrier 2 to move onto or away from the transfer track 1. See details below. Figure 5 When the material carrier 2 enters from one end of the water tank 3 and exits from the other end, water-stopping components 41 need to be installed at both ends of the water tank 3. The water-stopping component 41 can have only a single guide surface 411, or it can be installed as follows: Figure 6 As shown, guide surfaces 411 are respectively provided on both sides of the water-stopping component 41; when the material carrier 2 enters and leaves the water tank 3 from the same end, the water tank 3 may only have a water-stopping component 41 at one end, but guide surfaces 411 need to be provided on both sides of the water-stopping component 41. Preferably, the water-stopping component 41 is a water-stopping block, but in other embodiments, the water-stopping component 41 may also be a baffle or the like.
[0032] The transfer device for flammable and explosive materials in this embodiment has a transfer track 1 placed in a water tank 3. The water in the water tank 3 can wet and clean the transfer track 1 and the parts of the material carrier 2 that come into contact with the transfer track 1 (specifically, the rolling element 21), reducing static electricity and compression caused by friction. This can significantly reduce the risk of explosion when the material carrier 2 moves along the transfer track 1, improve safety, and facilitate automated transfer (e.g., by pushing the material carrier 2 along the transfer track 1 through a push-pull mechanism, or by having the rolling element 21 itself have driving force, such as by driving the rolling element 21 to roll through a hydraulic motor, which can avoid the risk of motors to energetic materials), and improve transfer efficiency. At least one end of the water tank 3 is provided with a water-stopping element 41 that can float up and down, and the water-stopping element 41 is provided with a guide surface 411. When the material carrier 2 needs to move to or leave the transfer track 1, the water-stopping element 41 can be lowered through the guide surface 411, so that it can pass smoothly and reduce the friction and compression between the material carrier 2 and the water-stopping element 41, thereby reducing the risk of explosion. After the material carrier 2 passes through, the water-stopping component 41 floats up, reducing water overflow in the water tank 3 and keeping the transfer track 1 submerged in water. The structure is simple and reliable.
[0033] See details Figures 4 to 6In this embodiment, the mounting base 4 is provided with a mounting groove 42, and an elastic reset member 43 is provided in the mounting groove 42. The elastic reset member 43 is located below the water-stop member 41. Under the gravity of the material carrier 2, the water-stop member 41 sinks, and the elastic reset member 43 is compressed and contracts. After the material carrier 2 passes through, the elastic reset member 43 unfolds, causing the water-stop member 41 to float automatically. The structure is simple and easy to use.
[0034] Furthermore, in this embodiment, a guide rod 44 is provided in the mounting groove 42, and the elastic reset member 43 is a helical spring sleeved on the guide rod 44. The guide rod 44 can provide positioning for the helical spring, preventing displacement or twisting of the helical spring after compression, thereby further improving reliability.
[0035] See details Figure 2 In this embodiment, the mounting base 4 is provided with a water inlet 45 on the side connected to the transfer track 1, and a drain outlet 46 is provided at the bottom of the mounting groove 42. The drain outlet 46 is connected to a drain pipe 5, and a drain valve 51 is provided on the drain pipe 5. When the water in the water tank 3 contains too much material, the drain valve 51 can be opened, and the water in the water tank 3 will be drained through the water inlet 45, the mounting groove 42, the drain outlet 46, and the drain pipe 5 in sequence, which helps to keep the water tank 3 clean and further reduces the risk of explosion.
[0036] See details Figure 5 and Figure 6 In this embodiment, there is a gap between the water-stopping component 41 and the water inlet 45, which can prevent the water-stopping component 41 from blocking the water inlet 45, thereby achieving smooth drainage.
[0037] In a preferred embodiment, the waterstop 41 is made of polytetrafluoroethylene (PTFE). The PTFE waterstop 41 has a smooth surface, is not prone to dust adhesion, has low friction when the material carrier 2 passes through, and also has advantages such as high temperature resistance, stable performance, and long service life.
[0038] See details Figure 2 In this embodiment, a spray pipe 6 is provided above the transfer track 1, and multiple spray sections 61 are provided on the spray pipe 6. The spray sections 61 can spray and clean the transfer track 1 and the rolling parts 21 to reduce the dust adhering to the transfer track 1 and the rolling parts 21, and further reduce the risk of explosion. On the other hand, they can replenish water in the water tank 3 to ensure the liquid level in the water tank 3.
[0039] See details Figure 3 In this embodiment, the top surface of the transfer track 1 is a convex arc surface. Setting the top surface of the transfer track 1 as a convex arc surface helps to reduce material residue on the top surface of the transfer track 1, further reducing the risk of explosion.
[0040] Furthermore, in this embodiment, the height of the apex of the arc surface is lower than the height of the water tank 3, which is beneficial for the transfer track 1 to be submerged in the water tank 3, ensuring the cleaning and wetting effect of the transfer track 1 and the rolling element 21.
[0041] In a preferred embodiment, the material carrier 2 is provided with a rolling element 21. The rolling element 21 and the transfer track 1 have rolling friction, resulting in low resistance. The shape of the rolling element 21 is adapted to the transfer track 1, which helps to prevent the rolling element 21 from disengaging from the transfer track 1, thus ensuring high reliability. The rolling element 21 is preferably a roller, but in other embodiments, it can also be a rolling bearing, etc.
[0042] 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.
