Description

Technical Field

[0001] The invention 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 Art

[0002] In the pharmaceutical and chemical industries, when materials are being dried, it is usually necessary to transfer the materials inside and outside the dryer. Generally, motors are used as drivers and the materials are transferred through automated methods such as rolling and sliding. However, when the transported materials are energetic materials (flammable and explosive), the production environment is required to be in F0 or F1 area. Traditional automated transport methods, whether rolling or sliding, will generate friction, static electricity, and extrusion, which can easily detonate energetic materials and cause safety accidents. Therefore, they cannot meet the use requirements. For this reason, manual transport is currently mostly used. On the one hand, manual transport is labor-intensive, and only a single material carrier can be transported at a time, which is inefficient, and dust endangers the health of workers. On the other hand, energetic solid materials are flammable and explosive, which poses a safety hazard. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a transfer device for flammable and explosive materials which is convenient for automatic transfer and has a simple structure and good safety.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A transfer device for flammable and explosive materials comprises a transfer track and a material carrier that can move along the transfer track, wherein the transfer track is arranged in a water trough, and a mounting seat is provided at at least one end of the water trough, and a water stop that can float up and down is provided on the mounting seat, and at least one guiding surface for guiding the material carrier to move to or leave the transfer track is provided on the water stop.

[0006] As a further improvement of the above technical solution: a mounting groove is provided on the mounting seat, an elastic reset member is provided in the mounting groove, and the elastic reset member is arranged below the water stop member.

[0007] As a further improvement of the above technical solution: a guide rod is provided in the installation groove, and the elastic reset member is a coil spring and is sleeved on the guide rod.

[0008] As a further improvement of the above technical solution: a water inlet is provided on the side where the mounting seat is connected to the transfer track, a drain outlet is provided at the bottom of the mounting groove, the drain outlet is connected to a drain pipe, and a drain valve is provided on the drain pipe.

[0009] As a further improvement of the above technical solution: there is a gap between the water stop member and the water inlet.

[0010] As a further improvement of the above technical solution: the material of the water stop is polytetrafluoroethylene.

[0011] As a further improvement of the above technical solution: a spray pipe is provided above the transfer track, and a plurality of spray parts are provided on the spray pipe.

[0012] As a further improvement of the above technical solution: the top surface of the transfer track is an upward convex arc surface.

[0013] As a further improvement of 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 of the above technical solution: a rolling member is provided on the material carrier, and the shape of the rolling member is adapted to the transfer track.

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] The transfer device for inflammable and explosive materials disclosed in the present invention sets the transfer track in a water tank. The water in the water tank can infiltrate and clean the transfer track and the parts of the material carrier that are in contact with the transfer track, reduce static electricity and extrusion caused by friction, and thus greatly reduce the risk of explosion when the material carrier moves along the transfer track, improve safety, facilitate automated transfer, and improve transfer efficiency; at least one end of the water tank is provided with a water stop that can float up and down, and the water stop is provided with a guide surface. When the material carrier needs to move to the transfer track or leave the transfer track, the water stop can be sunk by the guide surface, so that it can pass smoothly, and reduce the friction and extrusion between the material carrier and the water stop, thereby reducing the risk of explosion. After the material carrier passes, the water stop floats up, reducing the overflow of water in the water tank, so that the transfer track remains immersed in water, and the structure is simple and the reliability is good.

[0017] Other features and advantages of the present invention will be described in detail in the following detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Figures 1 to 7An embodiment of the transfer device for flammable and explosive materials of the present invention is shown. The transfer device for flammable and explosive materials of this embodiment comprises a transfer track 1 and a material carrier 2 that can move along the transfer track 1. The transfer track 1 is arranged in a water tank 3. At least one end of the water tank 3 is provided with a mounting seat 4. The mounting seat 4 is provided with a water stop 41 that can float up and down. The water stop 41 is provided with at least one guiding surface 411 for guiding the material carrier 2 to move onto the transfer track 1 or leave the transfer track 1. For details, see Figure 5 When the material carrier 2 enters the water tank 3 from one end and leaves from the other end, water stoppers 41 need to be provided at both ends of the water tank 3. The water stoppers 41 may only be provided with a single guide surface 411. Of course, it may also be provided as Figure 6 As shown, guide surfaces 411 are respectively provided on both sides of the water stop 41; and when the material carrier 2 enters and leaves the water tank 3 from the same end, the water tank 3 may only be provided with a water stop 41 at one end, but guide surfaces 411 need to be respectively provided on both sides of the water stop 41. Preferably, the water stop 41 is a water stop block, and of course in other embodiments, the water stop 41 may also be a baffle or the like.

[0032] The transfer device for flammable and explosive materials of this embodiment sets the transfer track 1 in the water tank 3. The water in the water tank 3 can soak and clean the transfer track 1 and the parts of the material carrier 2 that contact the transfer track 1 (specifically the rolling element 21), thereby reducing static electricity and extrusion generated by friction, thereby greatly reducing the risk of explosion when the material carrier 2 moves along the transfer track 1, improving safety, facilitating automated transfer (for example, the material carrier 2 is pushed to move along the transfer track 1 by a push-pull mechanism, or the rolling element 21 itself has a driving force, such as a hydraulic motor drives the rolling element 2 to roll, etc., which can avoid the risk of the motor to energetic materials), and improving transfer efficiency; at least one end of the water tank 3 is provided with a water stop 41 that can float up and down, and a guide surface 411 is provided on the water stop 41. When the material carrier 2 needs to move to the transfer track 1 or leave the transfer track 1, the water stop 41 can be sunk by the guide surface 411, so that it can pass smoothly, and reduce the friction and extrusion between the material carrier 2 and the water stop 41, thereby reducing the risk of explosion. After the material carrier 2 passes through, the water stop 41 floats up, reducing the water overflow in the water tank 3, so that the transfer track 1 remains immersed in the water with a simple structure and good reliability.

[0033] See Figures 4 to 6 In this embodiment, the mounting seat 4 is provided with a mounting groove 42, in which an elastic reset member 43 is provided, and the elastic reset member 43 is provided 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 contracted. After the material carrier 2 passes, the elastic reset member 43 unfolds, so that the water stop member 41 automatically floats up, which has a simple structure and is 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 coil spring and is sleeved on the guide rod 44. The guide rod 44 can provide a positioning operation for the coil spring to prevent displacement or distortion of the coil spring after being compressed, thereby further improving reliability.

[0035] See Figure 2 In this embodiment, a water inlet 45 is provided on one side of the mounting seat 4 connected to the transfer track 1, a drain port 46 is provided at the bottom of the mounting groove 42, the drain port 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 at this time, and the water in the water tank 3 is drained through the water inlet 45, the mounting groove 42, the drain port 46 and the drain pipe 5 in sequence, which is conducive to keeping the water tank 3 clean and further reducing the risk of explosion.

[0036] See Figure 5 and Figure 6 In this embodiment, there is a gap between the water stop member 41 and the water inlet 45, which can prevent the water stop member 41 from blocking the water inlet 45, thereby achieving smooth drainage.

[0037] As a preferred embodiment, the water stop 41 is made of polytetrafluoroethylene. The water stop 41 made of polytetrafluoroethylene has a smooth surface, is not easy to adhere to dust, has low friction when the material carrier 2 passes through, and has the advantages of high temperature resistance, stable performance and long service life.

[0038] See Figure 2 In this embodiment, a spray pipe 6 is provided above the transfer track 1, and a plurality of spray parts 61 are provided on the spray pipe 6. The spray parts 61 can spray and clean the transfer track 1 and the rolling element 21, reduce the dust adhering to the transfer track 1 and the rolling element 21, and further reduce the risk of explosion. On the other hand, the water tank 3 can be replenished with water to ensure the liquid level in the water tank 3.

[0039] See Figure 3 In this embodiment, the top surface of the transfer track 1 is an upward convex arc surface. The top surface of the transfer track 1 is set as an upward convex arc surface, which is conducive to reducing the residue of materials on the top surface of the transfer track 1 and further reducing the risk of explosion.

[0040] Furthermore, in the present embodiment, the height of the apex of the arc surface is lower than the height of the water tank 3 , which is conducive to immersing the transfer track 1 in the water tank 3 , thereby ensuring the cleaning and wetting effects of the transfer track 1 and the rolling element 21 .

[0041] As a preferred embodiment, a rolling element 21 is provided on the material carrier 2, and there is rolling friction between the rolling element 21 and the transfer track 1, with low resistance; the shape of the rolling element 21 is adapted to the transfer track 1, which is conducive to preventing the rolling element 21 from being separated from the transfer track 1, and has good reliability. Among them, the rolling element 21 is preferably a roller, and of course in other embodiments, the rolling element 21 can also be a rolling bearing, etc.

[0042] Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. Any technician familiar with the art can make many possible changes and modifications to the technical solution of the present invention by using the technical content disclosed above without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention should fall within the scope of protection of the technical solution of the present invention.
