Description

Technical Field

[0001] This utility model relates to the technical field of powder vibration screening, and in particular to a multi-stage powder vibration screening device. Background Technology

[0002] Powder vibrating screens, with their high efficiency, precision, and adaptability, are widely used in various industries such as chemical, mining, food, pharmaceutical, and building materials. They play an important role in key processes such as material classification, impurity removal, and particle size analysis, greatly improving production efficiency and product quality, and thus have become an indispensable key piece of equipment in modern industrial production.

[0003] Traditional powder vibrating sieving devices typically use a motor-driven crank-connecting rod mechanism to achieve vibration. This simple and low-cost method played a vital role in early industrial production. However, due to the low vibration frequency produced, sieving efficiency and accuracy are limited, and it cannot simultaneously sieve powders of various particle sizes, failing to meet the demands of modern industry for high output and high precision.

[0004] Therefore, it is necessary to design a multi-stage powder vibrating sieve device to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the shortcomings of traditional devices that have low vibration frequency and cannot simultaneously screen powders of various particle sizes, this utility model provides a multi-stage powder vibration screening device.

[0006] This utility model provides a multi-stage powder vibrating sieving device, including a dustproof shell, a feed plate, a discharge plate, a guide plate, a vibrating motor, connecting blocks, damping springs, a support frame, screens, hexagonal bolts, and a guide plate. The feed plate is slidably fitted on the top of the dustproof shell, and the top of the feed plate has a feed inlet. The discharge plate is fixedly connected to the front side of the dustproof shell. The guide plate is fixedly connected to the bottom of the dustproof shell, and two vibrating motors are fixedly connected to the bottom of the guide plate. Four connecting blocks are fixedly connected in a rectangular array at the bottom of the dustproof shell. Each connecting block is fixedly connected to the bottom of its damping springs, and a support frame is fixedly connected between the bottoms of the four damping springs. Each connecting block is slidably connected to the support frame. Two screens are fixedly connected to the inner wall of the dustproof shell by hexagonal bolts. The guide plate is fixedly connected to the bottom of the inner wall of the dustproof shell.

[0007] Preferably, a screen cleaning mechanism is also included, which includes a filter plate, rings and bouncing balls. A filter plate is fixedly connected to the bottom of each screen, and four rings are placed between each filter plate and the corresponding screen, with three bouncing balls placed inside each ring.

[0008] Preferably, the system also includes a receiving mechanism, which includes a receiving frame and rollers. The receiving frame is slidably engaged with the center of the front side of the support frame. Four rollers are rotatably connected to the bottom of the receiving frame in a rectangular array, and a handle is provided on the upper front side of the receiving frame.

[0009] Preferably, the device also includes a fixing block, a handle, a connecting rod, a clamping element, and a hook. The upper rectangular array of the dustproof housing is fixedly connected to four fixing blocks, each fixing block is rotatably connected to a handle, the middle of the handle is rotatably connected to a connecting rod, and the middle of the handle is rotatably connected to a clamping element. The clamping element can be hooked onto the fixing block when rotated downwards. The upper rectangular array of the feed plate is fixedly connected to four hooks, and each connecting rod can be hung on the corresponding hook.

[0010] Preferably, the two screens have different sieve apertures, which are coarse and fine screens from top to bottom.

[0011] As a preferred option, the discharge plate has three staggered discharge ports.

[0012] The beneficial effects of this utility model are as follows: 1. By setting up a multi-layer screen structure, this utility model can screen materials into three different particle size grades at one time to meet various particle size requirements. Under the linear reciprocating vibration generated by the vibrating motor, the material jumps along the screen surface, fully contacting the screen surface and improving the screening efficiency.

[0013] 2. This utility model utilizes the characteristics of bouncing balls, allowing them to repeatedly bounce and impact the screens below each layer of screen, effectively removing fine powder particles adhering to the screens, preventing screen blockage, improving the screening rate, and ensuring the continuous operation of the screening process.

[0014] 3. This utility model, through the cooperation of components such as handle, connecting rod and clamping parts, allows operators to quickly change or clean the screen by pressing the clamping parts and pulling the handle, adapting to changes in different material types and particle size distributions, and ensuring the hygiene and efficiency of the equipment during long-term operation.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Example: A multi-stage powder vibrating sieve device, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, the device includes a dustproof housing 1, a feed plate 2, a discharge plate 3, a guide plate 4, a vibrating motor 5, a connecting block 6, a shock-absorbing spring 7, a support frame 8, a screen 9, hexagonal bolts 13, and a guide plate 14. The feed plate 2 is slidably fitted onto the top of the dustproof housing 1, and a feed inlet is opened on the rear side of the top of the feed plate 2. The discharge plate 3 is welded to the front side of the dustproof housing 1, and the discharge plate 3 has three staggered discharge outlets. The guide plate 4 is welded to the bottom of the dustproof housing 1, and the vibrating motor is symmetrically mounted on the bottom of the guide plate 4 by bolts. The motor 5, the connecting blocks 6 are symmetrically welded to the left and right sides of the lower part of the dustproof shell 1, the shock-absorbing spring 7 is welded to the bottom of each connecting block 6, the support frame 8 is welded between the bottoms of the four shock-absorbing springs 7, and each connecting block 6 is slidably connected to the support frame 8. The inner wall of the dustproof shell 1 is fixedly connected to two screens 9 by hexagonal bolts 13. The two screens 9 have different screening apertures, and from top to bottom they are coarse screen and fine screen. The guide plate 14 is welded to the bottom of the inner wall of the dustproof shell 1.

[0026] like Figure 1 and Figure 6 As shown, it also includes a receiving mechanism, which includes a receiving frame 15 and rollers 16. The receiving frame 15 is slidably engaged with the middle of the front side of the support frame 8. The bottom of the receiving frame 15 is rotatably connected to four rollers 16 in a rectangular array, and the upper front side of the receiving frame 15 is provided with a handle.

[0027] When this device is needed to assist in powder sieving, the operator first places the device on a level surface to ensure its stability. Then, the vibrating motor 5 is started. The two vibrating motors 5 rotate in opposite directions, and the excitation force vector is superimposed to generate linear reciprocating motion. The vibration force is effectively transmitted to the dustproof shell 1 through the guide plate 4, causing the entire dustproof shell 1 to vibrate as needed. The damping spring 7 reduces unnecessary shaking and displacement of the dustproof shell 1, ensuring that the vibration is mainly concentrated in the required areas, protecting the device from excessive wear. Under the action of the support frame 8, the device can remain stable during vibration. Then, the operator can pour the material into the feed plate 2 through the feed inlet. Inside the dustproof housing 1, the material is sieved into three different particle sizes by the screen 9. Due to the vibration of the vibrating motor 5, the material jumps along the screen 9 towards the discharge plate 3. After thorough screening, the three sieved materials are guided to their respective discharge ports by the discharge plate 3 and fall into the receiving frame 15 through the discharge ports, thereby achieving continuous and efficient graded discharge operation. After screening is completed, the vibrating motor 5 can be turned off. When the receiving frame 15 is full, first pull the handle forward to pull the receiving frame 15 out smoothly with the help of the roller 16. Then, take the material out of the receiving frame 15. Finally, push the handle backward to make the receiving frame 15 slide back to the initial position.

[0028] like Figure 3 and Figure 5 As shown, it also includes a screen cleaning mechanism, which includes a filter plate 10, rings 11, and bouncing balls 12. The bottom of each screen 9 is fitted with a filter plate 10 by screws. Four rings 11 are placed between each filter plate 10 and the corresponding screen 9, and three bouncing balls 12 are placed inside each ring 11.

[0029] When there is too much material to be screened, the bouncing ball 12 can repeatedly bounce between the filter plate 10 and the screen 9 during the vibration process, continuously bouncing and hitting the screen 9 to clean up the adhering material, improve the screening rate and prevent the screen holes from clogging. The collar 11 can restrict the movement of the bouncing ball 12 and prevent the bouncing ball 12 from deviating during the bouncing process.

[0030] like Figure 8 As shown, it also includes a quick-release mechanism, which includes a fixing block 17, a handle 18, a connecting rod 19, a clamping member 20, and a hook 21. The fixing blocks 17 are symmetrically welded to the front and rear sides of the upper part of the dustproof shell 1. The handle 18 is rotatably connected to each fixing block 17. The connecting rod 19 is rotatably connected to the middle of the handle 18. The clamping member 20 is rotatably connected to the middle of the handle 18. The clamping member 20 can be hooked on the fixing block 17 by rotating downward. The hooks 21 are symmetrically welded to the front and rear sides of the upper part of the feed plate 2. Each connecting rod 19 can be hung on the corresponding hook 21.

[0031] When cleaning the screen 9 is required, first turn off the vibration motor 5, then rotate the clamping member 20 upwards so that the clamping member 20 is no longer in contact with the fixing block 17, then pull the handle 18 upwards to drive the connecting rod 19 away from the hook 21, then take out the feed plate 2 upwards, then rotate the hexagonal bolt 13 in the forward direction to detach the screen 9 from the dustproof shell 1, then thoroughly clean and dry the screen 9, then rotate the hexagonal bolt 13 in the reverse direction to re-fix the screen 9 onto the dustproof shell 1, and put the feed plate 2 onto the dustproof shell 1, finally pull the handle 18 downwards to drive the connecting rod 19 back onto the hook 21, and press the clamping member 20 to hook the fixing block 17, so that the feed plate 2 and the dustproof shell 1 are firmly connected to prevent loosening due to vibration or external force.

[0032] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
