Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, and in particular to a raw material filtration device for high-fluorine tungsten production. Background Technology

[0002] High-fluorine tungsten usually refers to tungsten hexafluoride, an inorganic compound composed of tungsten and fluorine. Its main components are tungsten powder and fluorine gas. Before using tungsten powder, it needs to be filtered to avoid impurities that would result in low purity of the tungsten powder and affect production quality.

[0003] In existing technologies, conventional filtration devices filter tungsten powder using only a single screen. When the workload is large, a significant amount of tungsten powder falls onto the screen surface, causing friction between the powder particles. This friction increases the inter-particle force, leading to rapid accumulation of tungsten powder in localized areas of the screen. Once accumulated, this accumulation hinders the smooth passage of subsequent tungsten powder through the screen, narrowing or even clogging the filtration channels. Consequently, it severely impacts the sieving efficiency of the tungsten powder, reducing the smoothness of the entire production process and the quality of the output. Therefore, it is necessary to improve the raw material filtration device for high-fluorine tungsten production to solve these problems. Utility Model Content

[0004] To overcome the problem that when a single screen is used to handle a large amount of tungsten powder, the powder particles rub against each other and easily accumulate and clog the screen surface.

[0005] The technical solution of this utility model is as follows: a raw material filtration device for high fluorine tungsten production, including a hollow barrel, a positioning ring fixedly connected inside the hollow barrel, an installation ring set on the positioning ring and the hollow barrel, a locking block fixedly connected on the installation ring, a screen fixedly connected on the installation ring, a top cover rotatably connected to the hollow barrel, a feed inlet fixedly connected to the top cover, a discharge outlet fixedly connected to the bottom of the hollow barrel, a vibration component installed on the hollow barrel, and a diversion component installed on the hollow barrel.

[0006] Preferably, the positioning ring has a matching slot at the corresponding position of the card block, and the card block is engaged inside the slot.

[0007] Preferably, the sieve is inverted conical in shape, which separates impurities from the tungsten powder.

[0008] Preferably, the diversion assembly includes a mounting bracket installed on a hollow barrel and a diversion plate fixedly connected to the mounting bracket, through which the incoming tungsten powder is diverted.

[0009] Preferably, the hollow barrel has a mounting slot at the corresponding position of the mounting bracket, and the mounting bracket is snapped into the mounting slot.

[0010] Preferably, the vibration assembly includes a protective shell fixedly connected inside the hollow barrel, a drive motor fixedly connected inside the protective shell, a positioning shaft fixedly connected to the output end of the drive motor, an eccentric block set on the positioning shaft, a bolt threadedly connected to the positioning shaft, a fixing frame fixedly connected to the outside of the hollow barrel, a spring fixedly connected to the bottom of the fixing frame, and a support leg fixedly connected to the end of the spring away from the fixing frame. The drive motor drives the eccentric block to rotate through the positioning shaft.

[0011] Preferably, the eccentric block has a through hole that matches the positioning shaft, and the eccentric block is mounted on the positioning shaft through the through hole, with the bolt in contact with the eccentric block.

[0012] The beneficial effects of this utility model are:

[0013] 1. The conical screen design, combined with the diversion plate and the screen vibration, causes the material to roll towards the center of the screen, ensuring full contact between the material and the screen. This effectively filters impurities from the material and prevents material from accumulating in one place, resulting in higher filtration efficiency and better filtration quality.

[0014] 2. The spring makes the vibration more obvious, improving the filtration efficiency. The eccentric block can be replaced, and it can be flexibly disassembled and replaced according to the needs of use, making it convenient and quick to use. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-5 This utility model provides an embodiment of a raw material filtration device for high-fluorine tungsten production, comprising a hollow barrel 1, a positioning ring 21 fixedly connected inside the hollow barrel 1, an mounting ring 22 disposed on the positioning ring 21 and the hollow barrel 1, a locking block 23 fixedly connected to the mounting ring 22, a screen 24 fixedly connected to the mounting ring 22, a top cover 25 rotatably connected to the hollow barrel 1, a feed inlet 26 fixedly connected to the top cover 25, a discharge outlet 27 fixedly connected to the bottom of the hollow barrel 1, a vibration assembly mounted on the hollow barrel 1, and a diversion assembly mounted on the hollow barrel 1. A flange is provided between the discharge outlet 27 and the hollow barrel 1, which can be connected by a connector and can be disassembled. When adding material, the top cover 25 is closed, and material is added through the feed inlet 26. The material is guided through the feed inlet 26 and then through the diversion assembly, thus dispersing the material before it falls onto the surface of the screen 24. The vibration of the vibrating assembly causes the material to slide down the side wall of the conical screen 24 for rapid screening. It also allows the mounting ring 22 to be disassembled along with the screen 24, removing impurities filtered out by the screen 24. The positioning ring 21 has a matching slot at the corresponding position of the locking block 23, and the locking block 23 engages inside the slot, positioning the mounting ring 22 and preventing it from shaking due to the vibration of the vibrating assembly, thus ensuring the stability of the mounting ring 22 and consequently the stability of the screen 24. The locking block 23 extends from the top of the mounting ring 22, making its position clearly visible, allowing the mounting ring 22 to be engaged inside the slot via the locking block 23. The screen 24 is an inverted cone shape, separating impurities from the tungsten powder. The conical design of the screen 24, combined with the vibration of the vibrating assembly, allows the material to slide down the inclined side wall of the screen 24, ensuring full contact with the screen and maximizing filtration.

[0023] Please see Figures 1-2 In this embodiment, the diversion assembly includes a mounting frame 31 installed on the hollow barrel 1 and a diversion plate 32 fixedly connected to the mounting frame 31. The diversion plate 32 guides the incoming tungsten powder, and the diversion plate 32 disperses the material, preventing the material from falling directly into the center of the screen 24 and falling near the edge of the screen 24, so that the material can fully contact the screen 24. The hollow barrel 1 has a mounting groove at the corresponding position of the mounting frame 31, and the mounting frame 31 is snapped into the mounting groove. The mounting groove positions the mounting frame 31, which can ensure the stability of the diversion plate 32 and the mounting frame 31 and prevent loosening.

[0024] Please see Figures 1-2 , Figures 4-5In this embodiment, the vibration assembly includes a protective shell 41 fixedly connected inside the hollow barrel 1, a drive motor 42 fixedly connected inside the protective shell 41, a positioning shaft 43 fixedly connected to the output end of the drive motor 42, an eccentric block 44 disposed on the positioning shaft 43, a bolt 45 threadedly connected to the positioning shaft 43, a fixing frame 46 fixedly connected to the outside of the hollow barrel 1, a spring 47 fixedly connected to the bottom of the fixing frame 46, and a support leg 48 fixedly connected to the end of the spring 47 away from the fixing frame 46. The eccentric block 44 is driven to rotate by the positioning shaft 43. The eccentric block 44 is driven to rotate at high speed by the drive motor 42, generating centrifugal force. This, combined with the spring 47, causes the hollow barrel 1 to vibrate, thereby improving the screening efficiency of the screen 24. The eccentric block 44 has a through hole that matches the positioning shaft 43, and the eccentric block 44 is installed on the positioning shaft 43 through the through hole. The bolt 45 contacts the eccentric block 44, and different sizes of eccentric blocks 44 can be replaced. The eccentric block 44 can be replaced according to the actual use needs, and disassembly is quick and convenient.

[0025] During operation, the drive motor 42 is started, driving the positioning shaft 43. The positioning shaft 43 drives the eccentric block 44, which rotates at high speed in conjunction with the spring 47, causing the hollow barrel 1 to vibrate. This causes the screen 24 to vibrate as well. The top cover 25 is closed, and material is fed in through the feed inlet 26. The material is guided into the hollow barrel 1 through the feed inlet 26 and falls onto the surface of the diversion plate 32. The diversion plate 32 guides the material to disperse it, and the dispersed material falls into the screen 24. Impurities are filtered through the screen 24, and the material passing through the screen 24 falls onto the surface of the protective shell 41. The protective shell 41 guides the material flow, preventing the feed material from contacting the drive motor 42 and the eccentric block 44. After filtration is complete, the top cover 25 can be opened, and the screen 24 can be removed through the mounting ring 22 to clean the impurities in the screen 24. The bolt 45 can be turned to unscrew the positioning shaft 43. Since the bolt 45 does not constrain the eccentric block 44, the eccentric block 44 can be disassembled and replaced.

[0026] Through the above steps, the conical screen 24, together with the diverting plate 32 and the vibration of the screen 24, will cause the material to roll towards the center of the screen 24 with the vibration, so that the material can fully contact the screen 24, thereby fully filtering the impurities in the material and preventing the material from accumulating in one place. This solves the problem that when a single screen 24 is used to deal with a large amount of tungsten powder, the tungsten powder will rub against each other and easily accumulate and clog on the surface of the screen 24.
