Description

Technical Field

[0001] This utility model relates to the field of filter plate preparation technology, specifically to a powder screening device for preparing gradient channel silicon carbide ceramic filter plates. Background Technology

[0002] Gradient-pore silicon carbide ceramic filter plates are high-performance filter materials that combine the excellent properties of silicon carbide ceramics with the unique advantages of their gradient-pore structure. The manufacturing process of gradient-pore silicon carbide ceramic filter plates involves using high-purity silicon carbide powder as raw material, adding appropriate amounts of binders and plasticizers, and forming the raw material into a green body of the desired shape using methods such as slip casting, dry pressing, or isostatic pressing. The green body is then dried at an appropriate temperature to remove moisture and organic solvents, and finally sintered at a high temperature. During the preparation of gradient-pore silicon carbide ceramic filter plates, the particle size distribution of the powder has a crucial impact on the performance of the final product, necessitating the use of a powder screening device.

[0003] Traditional powder screening devices for preparing gradient-pore silicon carbide ceramic filter plates use a sieve to screen the powder. Because the sieve is directly connected to the device and cannot be moved, some powder accumulates on the sieve, causing blockages and affecting the normal operation of the device. To solve this problem, some powder screening devices for preparing gradient-pore silicon carbide ceramic filter plates have a movable connection between the sieve and the device, and a vibration component is added to the corresponding part of the sieve. This causes the sieve to vibrate on the device, allowing the powder to pass through and avoiding powder blockage and affecting the operation of the device. However, this method, due to the vibration of the sieve, not only shortens its service life but also makes it prone to loosening. Therefore, a powder screening device for preparing gradient-pore silicon carbide ceramic filter plates is proposed. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a powder screening device for preparing gradient-pore silicon carbide ceramic filter plates, thereby solving the aforementioned technical problems of not only shortening service life but also being prone to loosening.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a powder screening device for preparing gradient-pore silicon carbide ceramic filter plates, comprising:

[0008] The device housing and the connecting cover plate set on the upper surface of the device housing, and the upper surface of the connecting cover plate is connected to the feed funnel, and the front and rear ends of the inner wall of the device housing are provided with rotating grooves, and the inner cavity of the rotating groove is provided with a screen plate.

[0009] The first drive motor is located on the right side of the outer wall of the device housing, and a rotating column is installed on the rotating end of the first drive motor, and a limit block is installed on the inner end of the rotating column, and the limit block is inserted and connected to the screen plate.

[0010] The outer plate is located on the left side of the outer wall of the device box and is rotatably connected to the screen plate. Positioning blocks are installed on both the left and right sides of the outer plate, and a circular plate is attached to the front of each positioning block. A cylindrical plate is installed above each circular plate and is rotatably connected to the outer wall of the device box. The screen plate is inserted into the inner cavity of the device housing by the outer plate. The screen plate is connected to the limiting block. The retaining plate rotates on the cylindrical plate under gravity and fits tightly with the positioning block. The powder is conveyed into the device housing through the feeding funnel and falls onto the upper surface of the screen plate. The first drive motor, connected to an external power source, drives the screen plate to rotate slightly in the rotating groove on the device housing, causing the powder to move on the upper surface of the screen plate and fall through the screen holes. The angle of rotation of the screen plate by the first drive motor in the rotating groove can be controlled by the controller. This is existing technology and will not be described in detail here. On the one hand, by rotating the screen plate to move and screen the powder, not only can the service life of the screen plate be guaranteed, but also the stability of the screen plate can be guaranteed. On the other hand, it is convenient to replace the screen plate.

[0011] Preferably, discharge side troughs are provided on both the left and right sides of the device housing, and second drive motors are installed on both the left and right sides of the back of the device housing. Unfiltered powder can be discharged outward through the discharge side troughs. The second drive motors are connected to an external power source and drive the connecting structure to rotate on the device housing, adjusting the direction of rotation of the connecting structure.

[0012] Preferably, the bottom of the inner cavity of each discharge side trough is rotatably connected to a rotating shaft, and the end of the rotating shaft is coaxially connected to the rotating end of the second drive motor. The second drive motor is powered by an external power source to drive the rotating shaft to rotate on the device housing and adjust the direction of rotation of the rotating shaft. At the same time, the two sets of second drive motors can be controlled simultaneously and in the direction of rotation by an external controller, etc. This is prior art, so it will not be described in detail here.

[0013] Preferably, the upper surface of each rotating shaft is equipped with a guide side plate, and the outer surface of the guide side plate is in close contact with the inner wall of the discharge side trough. The guide side plates rotate in the same direction as the rotating shaft, so that the two sets of guide side plates rotate and fit together in the inner cavity of the device box. When the first drive motor is connected to an external power source and drives the screen plate to rotate significantly, the unqualified powder on the screen plate falls down onto the guide side plate and rolls along the guide side plate to the outside of the discharge side trough, thereby facilitating the cleaning operation of the unqualified powder on the screen plate.

[0014] Preferably, the lower surface of the device housing is connected to a discharge base, and support columns are installed around the outer perimeter of the device housing. Powder passing through the screen plate is discharged to the outside of the device housing via the discharge base, and the support columns provide support for the device housing.

[0015] Preferably, the positioning block has a T-shaped design and is inserted into the outer wall of the device housing. The positioning block allows the outer panel to be accurately inserted into the device housing.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a powder screening device for preparing gradient-pore silicon carbide ceramic filter plates, which has the following beneficial effects:

[0018] This powder screening device for preparing gradient-channel silicon carbide ceramic filter plates uses an outer plate to drive a screen plate into the inner cavity of the device housing. The screen plate is connected to a limiting block, and a retaining plate rotates on a cylindrical plate under gravity to fit tightly against the positioning block. Powder is conveyed into the device housing through a feeding funnel and falls onto the upper surface of the screen plate. The first drive motor, connected to an external power source, drives the screen plate to rotate slightly in the rotating groove on the device housing, causing the powder to move on the upper surface of the screen plate and fall through the screen holes. By rotating the screen plate, the powder is moved and screened, which not only ensures the service life and stability of the screen plate, but also facilitates the replacement of the screen plate.
