Description

Technical Field

[0001] This utility model relates to the technical field of sponge titanium screening equipment, specifically a sponge titanium screening device. Background Technology

[0002] Titanium sponge is a form of metallic titanium, named for its sponge-like appearance. It is an intermediate product in the titanium processing process, obtained by reducing titanium compounds through methods such as magnesothermic reduction or sodium-thermal reduction. Titanium sponge is an important material for manufacturing aircraft engine parts, fuselage structural components, and so on.

[0003] A search revealed a sponge titanium screening device disclosed in Chinese Patent Publication No. CN219253187U. The screen cylinder component includes at least two layers of screening cylinders, each with screen holes on its wall. The size of the screen holes gradually decreases from the inner layer to the outer layer. Each layer of screening cylinders has a discharge hole at its discharge end. This design avoids frequent clogging of the screen holes during the screening process and allows for convenient and quick unclogging of the screening device when the screen holes become blocked.

[0004] However, in the prior art, during the sieving process of sponge titanium, the friction between particles and between particles and the screen generates static electricity, causing the sponge titanium particles to adhere to the screen or clump together. In order to solve the problem that the particles adsorbed on the screen also cause screen blockage in the prior art, this application proposes to set up a static electricity elimination mechanism to avoid the static electricity generated by the friction between particles and between particles and the screen, thereby preventing the sponge titanium particles from adsorbing each other and thus avoiding the problem of screen blockage. Therefore, a new solution is needed to solve this problem. Utility Model Content

[0005] The existing technology mentioned above has the shortcomings and defects of generating static electricity through friction between particles and between particles and the screen, which causes the sponge titanium particles to be adsorbed on the screen or to clump together, resulting in screen blockage.

[0006] The sponge titanium screening device disclosed in this utility model includes a box body, a filter screen is provided inside the box body, a rotating shaft is provided above the filter screen, an electrostatic eliminator is provided between the rotating shaft and the filter screen, a fixing component is provided between the electrostatic eliminator and the rotating shaft, and a vibration motor is provided at the lower end of the box body.

[0007] Furthermore, the fixing component includes a fixing plate one and a fixing plate two. The fixing plate one is installed on the static elimination rod, and the fixing plate two is installed on the rotating shaft. One end of the fixing plate one is provided with a clamping plate, and the other end of the fixing plate one is provided with a fastener. The fixing plate two is provided with a slot at the corresponding position of the clamping plate, and the clamping plate engages with the slot.

[0008] Furthermore, the fastener includes a threaded rod, which is rotatably mounted on the fixing plate, and a fastening cap is provided on the threaded rod, which is threadedly connected to the threaded rod.

[0009] Furthermore, one end of the rotating shaft passes through the housing, and a first bevel gear and a second bevel gear are mounted on the rotating shaft. An incomplete bevel gear is provided between the first bevel gear and the second bevel gear, and a drive source is provided between the incomplete bevel gear and the housing.

[0010] Furthermore, the filter screen is provided with multiple filters, and the through holes on the multiple filters gradually decrease in size from the upper layer to the lower layer. The housing is provided with multiple discharge ports.

[0011] Furthermore, the upper end of the box is provided with a feed inlet and a cover plate. One end of the cover plate is connected to the box via a hinge, and the other end of the cover plate is provided with a buckle to the box.

[0012] Furthermore, the rotating shaft is horizontally positioned in the middle of the housing and is located below the cover plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model is equipped with components such as a vibration motor, a filter screen, an antistatic rod, and a rotating shaft. During operation, the vibration motor and filter screen components work together to screen the sponge titanium. The rotating shaft confines the antistatic rod inside the box, and the antistatic rod generates ion wind to neutralize the static electricity on the surface of the sponge titanium, thereby preventing the sponge titanium particles from adsorbing onto the screen or clumping together, which would cause the screen to become clogged.

[0015] 2. This utility model includes components such as a first bevel gear, a second bevel gear, an incomplete bevel gear, a clamping plate, a threaded rod, and a fastening cap. During operation, the first bevel gear, the second bevel gear, and the incomplete bevel gear work together to adjust the rotation of the incomplete bevel gear. As the incomplete bevel gear rotates, it meshes with either the first or the second bevel gear in sequence, thereby achieving the reciprocating oscillation of the shaft. This improves the static removal effect of the static eliminator during operation. Furthermore, the clamping plate, the threaded rod, and the fastening cap work together to facilitate the installation and removal of the first and second fixing plates, making it convenient for disassembly, maintenance, and replacement of the static eliminator.

[0022] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0023] Please see Figure 1 , Figure 2 The sponge titanium screening device of this utility model includes a box body 1, a filter screen 2 is provided inside the box body 1, a rotating shaft 4 is provided above the filter screen 2, an electrostatic eliminator 5 is provided between the rotating shaft 4 and the filter screen 2, a fixing component is provided between the electrostatic eliminator 5 and the rotating shaft 4, and a vibration motor 3 is provided at the lower end of the box body 1.

[0024] like Figure 3 , Figure 4 As shown, the fixing assembly includes a first fixing plate 6 and a second fixing plate 7. The first fixing plate 6 is mounted on the static elimination rod 5, and the second fixing plate 7 is mounted on the rotating shaft 4. One end of the first fixing plate 6 is provided with a retaining plate 8, and the other end of the first fixing plate 6 is provided with a fastener. The second fixing plate 7 at the corresponding position of the retaining plate 8 is provided with a retaining groove 9. The retaining plate 8 and the retaining groove 9 engage with each other. Through the mutual cooperation between the retaining plate 8 and the retaining groove 9, one end of the first fixing plate 6 and the second fixing plate 7 can be conveniently connected, which facilitates subsequent disassembly.

[0025] In this embodiment, the fastener includes a threaded rod 10, which is rotatably mounted on a first fixing plate 6. A fastening cap 11 is provided on the threaded rod 10, and the fastening cap 11 is threadedly connected to the threaded rod 10. The fastening cap 11 is adjusted to rotate on the threaded rod 10. When the fastening cap 11 moves away from the second fixing plate 7, the fixing restriction between the first fixing plate 6 and the second fixing plate 7 is released. When the fastening cap 11 moves toward the second fixing plate 7, it squeezes the second fixing plate 7, thereby fixing one end of the first fixing plate 6 and the second fixing plate 7.

[0026] like Figure 3 As shown, one end of the rotating shaft 4 passes through the housing 1. A bevel gear 12 and a bevel gear 2 13 are mounted on the rotating shaft 4. An incomplete bevel gear 14 is provided between the bevel gear 12 and the bevel gear 2 13. A drive source is provided between the incomplete bevel gear 14 and the housing 1. For the drive source, such as a servo motor commonly found in the market, the specific structure and working principle will not be described or limited in detail here. The servo motor drives the incomplete bevel gear 14 to rotate, the incomplete bevel gear 14 drives the bevel gear 12 to rotate, and the bevel gear 12 drives the rotating shaft 4 to rotate. As the incomplete bevel gear 14 rotates, it separates from the bevel gear 12 and meshes with the bevel gear 2 13. At this time, the bevel gear 2 13 drives the rotating shaft 4 to rotate in another direction, thereby realizing the reciprocating swing of the static elimination rod 5.

[0027] Looking back Figure 2 As shown, multiple filter screens 2 are provided, and the through holes on the multiple filter screens 2 gradually decrease in size from the upper layer to the lower layer. Multiple discharge ports 17 are provided on the box body 1. A feed port 16 and a cover plate 15 are provided at the upper end of the box body 1. One end of the cover plate 15 is connected to the box body 1 by a hinge, and the other end of the cover plate 15 is provided with a buckle between it and the box body 1. The cover plate 15 is opened to facilitate the maintenance and disassembly of the internal parts by the staff.

[0028] In this embodiment, the rotating shaft 4 is horizontally arranged in the middle of the housing 1, and the rotating shaft 4 is located below the cover plate 15.

[0029] The implementation principle is as follows: First, the material is fed into the feed port 16, and then the material falls onto the filter screen 2. At the same time, the vibration motor 3 drives the housing 1 to move, and the housing 1 drives the filter screen 2 to vibrate, so that the material falls off the filter screen 2. The filtered material is sent out from the discharge port 17. While screening the material, the servo motor drives the incomplete bevel gear 14 to rotate. The incomplete bevel gear 14 drives bevel gear 12 or bevel gear 13 to rotate, and at the same time drives the rotating shaft 4 to rotate. The rotating shaft 4 drives the static elimination rod 5 to swing. The static elimination rod 5 removes static electricity from the material rubbing on the filter screen 2, thereby preventing the material from attracting each other and causing the filter screen 2 to become clogged.

[0030] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
