Description

Technical Field

[0001] This utility model relates to the field of sieves, and in particular to a new centrifuge sieve structure. Background Technology

[0002] Centrifuge screens are commonly used to separate substances of different particle sizes and densities. Their structural design is crucial to the separation effect. The screens are usually mounted on a frame or support to ensure their stability and support under centrifugal force.

[0003] A search revealed Chinese Patent Publication No. CN220461011U, which discloses a centrifuge screen basket for easy screen replacement. The basket includes a flange, with several partition plates fixedly connected to the top of the flange. An arc-shaped screen plate is positioned between opposite sides of two adjacent partition plates. An annular cover plate is fixedly installed on the top of the partition plates, with several first threaded holes on the top of the annular cover plate. Second threaded holes, matching the first threaded holes, are also provided on the top of the partition plates. This invention relates to the field of centrifuge screen basket technology. This centrifuge screen basket, which facilitates screen replacement, allows for easy removal and replacement of damaged arc-shaped screen plates by rotating multiple threaded rods, which in turn rotate out of the multiple first and second threaded holes. This allows the annular cover plate to be removed from the partition plates, enabling convenient removal and replacement of the damaged arc-shaped screen plate without replacing the entire screen in the basket, thus significantly reducing production costs.

[0004] While the aforementioned device facilitates the replacement of the arc-shaped screen plate through the interplay of components such as the threaded rod, annular cover plate, partition plate, and arc-shaped screen, the lack of a connecting structure between the arc-shaped screen plate and the partition plate, due to the installation and limiting plates only being located at the top and bottom, leads to a situation where the material being filtered impacts the screen. Prolonged impact can create gaps between the arc-shaped screen plate and the partition plate, affecting the centrifuge's separation efficiency. Furthermore, the varying contact time between the filter and material in different areas during centrifugal operation results in inconsistent damage and lifespan across different screen regions. Replacing the entire arc-shaped screen plate would waste even the less damaged sections, increasing maintenance costs and making it impractical. Therefore, a new centrifuge screen structure is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a new centrifuge screen structure, aiming to improve the existing technology. Although the existing technology allows for easier replacement of the arc-shaped screen plate through the cooperation of components such as threaded rods, annular cover plates, partition plates, and arc-shaped screens, the arc-shaped screen plate only has mounting plates and limiting plates at the top and bottom. This results in no connecting structure between the arc-shaped screen plate and the partition plate. During centrifugal filtration, the filtered material will impact the screen, and prolonged impact can easily create gaps between the arc-shaped screen plate and the partition plate, thus affecting the separation effect of the centrifuge.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a new centrifuge screen structure, including a mounting frame, wherein multiple screen plates are provided on both the upper and lower parts of the mounting frame, multiple limit rods are provided on both the upper and lower parts of the mounting frame, the mounting frame includes multiple partition rods, a connecting groove is opened in the middle of the partition rod, and connecting strips are fixedly connected to the left and right sides of the screen plates, the connecting strips being movably connected to the connecting grooves.

[0007] As a further description of the above technical solution:

[0008] A fixing rod is fixedly connected between the middle parts of two adjacent partition rods.

[0009] As a further description of the above technical solution:

[0010] The fixing rod has fixing grooves on both the upper and lower sides.

[0011] As a further description of the above technical solution:

[0012] The screen plate is fixedly connected to both the upper and lower sides by fixing strips.

[0013] As a further description of the above technical solution:

[0014] The fixing strip located on the lower side of the upper screen plate and the fixing strip located on the upper side of the lower screen plate are respectively movably connected to the fixing grooves on the upper and lower sides of the fixing rod.

[0015] As a further description of the above technical solution:

[0016] One end of the limiting rod is fixedly connected to a first mounting plate, and the other end of the limiting rod is fixedly connected to a second mounting plate.

[0017] As a further description of the above technical solution:

[0018] Limiting grooves are provided on the lower side of the upper limiting rod and the upper side of the lower limiting rod. The fixing strip on the upper side of the upper screen plate and the fixing strip on the lower side of the lower screen plate are movably connected to the limiting grooves on the upper and lower limiting rods, respectively.

[0019] As a further description of the above technical solution:

[0020] The upper and lower parts of the partition rod are connected to the No. 1 and No. 2 mounting plates by bolts.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by setting the screen plate and connecting strip, the stability of the screen plate installation can be ensured, and the gap between the screen plate and the mounting frame due to impact during use can be prevented, which would affect the use of the centrifuge, making it more practical.

[0023] 2. In this utility model, by setting the partition strip and the fixing rod, as well as the cooperation between the screen plate and the limiting rod, the screen plate is made smaller in size. This allows the screen plate on the overall screen structure to be divided into different areas, making it easier to replace the screen plate in areas that are prone to damage, thereby reducing maintenance costs and making it more practical.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 - Figure 2 This utility model provides an embodiment of a new centrifuge screen structure, including a mounting frame 1 for mounting multiple screen plates 3. Multiple screen plates 3 are provided on both the upper and lower parts of the mounting frame 1. The upper screen plate 3 has a larger volume than the lower one and is an arc-shaped plate used for centrifuge sieving. Multiple limiting rods 2 are provided on both the upper and lower parts of the mounting frame 1 for assisting in fixing the screen plates 3. These rods are arc-shaped. The mounting frame 1 includes multiple partition rods 11 for assisting in connecting components. A connecting groove 111 is formed in the middle of the partition rod 11. Connecting strips 32 are fixedly connected to the left and right sides of the screen plates 3 for connecting the screen plates 3 and the partition rods 11. The connecting strips 32 are movably connected to the connecting grooves 111 and are adapted to each other. Fixed strips 31 are fixedly connected to the upper and lower sides of the screen plates 3 for cooperating with the screen plates 3 and the fixing rods 12, as well as for limiting.

[0032] like Figure 3 As shown, a fixing rod 12 is fixedly connected between the middle of two adjacent partition rods 11. It is used to cooperate with the installation of the screen plate 3. Fixing grooves 121 are provided on the upper and lower sides of the fixing rod 12. They are used to cooperate with the installation of the fixing strip 31. The fixing strip 31 located on the lower side of the upper screen plate 3 and the fixing strip 31 located on the upper side of the lower screen plate 3 are movably connected to the fixing grooves 121 on the upper and lower sides of the fixing rod 12, respectively.

[0033] Please see Figure 4One end of the limiting rod 2 is fixedly connected to a first mounting plate 21, which is used to connect with the partition rod 11. The other end of the limiting rod 2 is fixedly connected to a second mounting plate 22, which is also used to connect with the partition rod 11. The first mounting plate 21 and the second mounting plate 22 are the same size, and the thickness of both mounting plates is half the thickness of the connecting strip 31. The first mounting plate 21 is fixed at a position further outward than the second mounting plate 22. The outer side of the second mounting plate 22 can fit against the inner side of the first mounting plate 21. The first mounting plate 21 and the second mounting plate 22 are fixed at a position further outward than the second mounting plate 22. Plate 22 is movably connected to connecting groove 111. Limiting grooves 23 are provided on the lower side of the upper limiting rod 2 and the upper side of the lower limiting rod 2, which are used to cooperate with the installation of screen plate 3. The fixing strip 31 on the upper side of the upper screen plate 3 and the fixing strip 31 on the lower side of the lower screen plate 3 are movably connected to the limiting grooves 23 on the upper and lower limiting rods 2, respectively. Bolts 13 are threadedly connected to the upper and lower parts of the partition rod 11 and the first mounting plate 21 and the second mounting plate 22, which are used to cooperate with the fixing between the limiting rod 2 and the partition rod 11.

[0034] Working principle: In use, firstly, install the upper screen plates 3 sequentially onto the mounting frame 1. During installation, align the connecting strips 32 on both sides of the screen plate 3 with the connecting grooves 111 on the two spacers 11, then insert the connecting strips 32 into the connecting grooves 111. Move the screen plate 3 downwards so that the connecting strips 32 at the bottom of the screen plate 3 are inserted into the fixing grooves 121 on the upper side of the fixing rod 12. After all the upper screen plates 3 are connected to the mounting frame 1, install the limiting rods 2 sequentially on the upper part of the screen plates 3, so that the fixing strips 32 on the screen plate 3 are inserted into the limiting grooves 23. The limiting rods 2 are positioned between two adjacent spacers 11, so that the first mounting plate 21 on one side and the second mounting plate 22 on the other side are respectively inserted into the connecting grooves 111 of the two spacers 11. Then install another limiting rod 2, so that the first mounting plate 21 on the other limiting rod 2 is attached to the second mounting plate 22 on the limiting rod 2. Then, use bolts 13 to fix the second mounting plate 22 on the limiting rod 2, the first mounting plate 21 on the other limiting rod 2, and the partition rod 11 connected thereto. Repeat the above operation. For the installation of the upper screen plate 3, when it is necessary to install the lower screen plate 3, first rotate the entire mounting frame 1 so that the mounting frame 1 rotates 180 degrees, so that the upper screen plate 3 moves to the lower part, thereby making the lower part of the partition rod 11 reverse to the upper part, which makes it easier to install the lower screen plate 3. Then repeat the above installation operation to complete the installation of the screen plate 3. When it is necessary to replace a screen plate 3, simply unscrew the bolts 13 on the limiting rod 2 connected to the corresponding screen plate 3 so that the limiting rod 2 can be removed from the mounting frame 1. Then take the screen plate 3 to be replaced from the mounting frame 1, and then install the new screen plate 3 on the mounting frame 1. Then fix the removed limiting rod 2 to the mounting frame 1.
