Description

Technical Field

[0001] This utility model relates to the field of dry powder sorting and slag removal technology, specifically to a rotor center cylinder sealing structure. Background Technology

[0002] Dry powder sorting refers to the process of effectively separating different components in dry powder materials using physical or mechanical methods. Dry powder sorting is widely used in various industries, such as mining, chemical, and food processing, primarily for removing impurities, improving material purity, or altering particle size distribution.

[0003] Currently, sealing of the dry powder sorting cylinder can be achieved, for example, using a sealing structure disclosed in CN201731748U. This structure includes a cylinder body and a discharge box fitted over one end of the cylinder body. A sealing device is provided between the discharge box and the cylinder body. The end of the discharge box covering the outside of the cylinder body is cylindrical. A sealing ring groove is provided on the outer circumference of the cylinder body, located outside the discharge box with its opening facing the discharge box. The sealing device includes a sealing ring, one end of which is fitted onto the cylinder, and the other end is inserted into the sealing ring groove. This utility model's drying cylinder sealing structure uses a sealing ring with one end fitted onto the cylinder and the other end inserted into the sealing ring groove. This structure is relatively simple and easy to install and maintain. Furthermore, the sealing ring, after being inserted into the sealing ring groove, forms a labyrinthine sealing structure, improving the sealing effect.

[0004] The shortcomings of the existing technology are that the gap between the existing dry powder sorting cylinder and the device cannot be well supported and sealed during operation. This makes the sorting cylinder prone to displacement during rotation, and allows dry powder to easily enter the gap between the sorting cylinder and the device. The accumulated dry powder will affect the rotation of the sorting cylinder, increase the wear between the sorting cylinder and the device, and thus affect the service life of the device and the sorting cylinder. Utility Model Content

[0005] To address this issue, the present invention provides a rotor center cylinder sealing structure to solve the problem in the prior art where the gap between the sorting cylinder and the device cannot be properly supported and sealed, leading to dry powder easily entering the gap and affecting the rotation of the sorting cylinder, while also increasing wear between the sorting cylinder and the device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rotor center cylinder sealing structure, including a sorting mechanism, and further comprising:

[0007] A sealing mechanism is installed on both sides of the sorting mechanism to seal both sides of the sorting mechanism;

[0008] The sealing mechanism includes a first fixed frame, a second fixed frame, and a sealing sleeve. A sealing ring is provided between the inner wall of the first fixed frame and the rotor of the sorting mechanism, and an oil seal is provided between the outer wall of the first fixed frame and the rotor of the sorting mechanism.

[0009] Preferably, the sorting mechanism includes a fixed housing, a feed inlet at the top of the fixed housing, a discharge outlet on the inner wall of one end of the fixed housing, a sorting cylinder rotatably mounted inside the fixed housing, and an installation groove on the outer wall of one side of the fixed housing.

[0010] Preferably, the inner wall of the mounting groove is movably connected to the first fixing frame and the second fixing frame, and the inner walls of the first fixing frame and the second fixing frame are threaded with a plurality of connecting bolts that are threaded to the inner wall of the mounting groove.

[0011] Preferably, the inner walls of the first and second fixing frames are provided with sealing grooves, the sealing grooves are movably sleeved on the outside of the sealing ring, and the sealing ring is movably sleeved on the outside of the sorting cylinder shaft.

[0012] Preferably, the outer walls of the first and second fixing frames away from the fixing housing are both provided with connecting grooves, and the two connecting grooves are movably sleeved on the outside of the oil seal, and the oil seal is movably sleeved on the outside of the sorting cylinder shaft.

[0013] Preferably, the outer wall of the fixed housing away from the mounting groove has a fixing groove, the inner wall of the fixing groove is movably connected to the sealing sleeve, the sealing sleeve is movably sleeved on the outside of the sorting cylinder shaft, and a plurality of fastening bolts that are threaded to the inner wall of the outer side of the sealing sleeve are threadedly inserted.

At the same time, the gap between the rotating shaft of the sorting cylinder and the fixed shell can be supported and sealed through the sealing sleeve plate. This makes the sorting cylinder stable during rotation and prevents dry powder from entering the gap between the rotating shaft of the sorting cylinder and the device during the sorting process. This can prevent dry powder from affecting the rotation of the sorting cylinder, reduce wear between the sorting cylinder and the device connection, and extend the service life of the device and the sorting cylinder.

At the same time, the sealing sleeve 208 can seal the inner wall between the rotating shaft of the sorting cylinder 104 and the device.

[0033] In order to ensure that the first fixing frame 201 and the second fixing frame 202 can stably install and fix the sorting cylinder 104, such as Figure 1-4 and Figure 6 As shown, the sorting mechanism 1 includes a fixed housing 101.

Multiple connecting bolts 203, which are threaded into the inner walls of the first fixed frame 201 and the second fixed frame 202, are threaded into the inner walls of the mounting groove 105. The inner diameter of the first fixed frame 201 and the second fixed frame 202 is the same as the outer diameter of the rotating shaft of the sorting cylinder 104. The outer diameter of the first fixed frame 201 and the second fixed frame 202 is the same as the outer diameter of the mounting groove 105. The mounting groove 105 can install and fix the first fixed frame 201 and the second fixed frame 202. The connecting bolt 203 passes through the first fixed frame 201 and the second fixed frame 202 and is threaded to the inner wall of the mounting groove 105, so that the first fixed frame 201 and the second fixed frame 202 can stably install and fix the sorting cylinder 104.

[0034] In order to ensure that the sealing ring 205 and the oil seal 207 stably seal the gap between the sorting cylinder 104 and the first fixed frame 201 and the second fixed frame 202, such as Figure 2-3 and Figure 6As shown, the inner walls of the first fixing frame 201 and the second fixing frame 202 are both provided with sealing grooves 204. The sealing grooves 204 are movably fitted on the outside of the sealing ring 205. The sealing ring 205 is movably fitted on the outside of the rotating shaft of the sorting cylinder 104. The outer walls of the first fixing frame 201 and the second fixing frame 202 away from the fixed housing 101 are both provided with connecting grooves 206. The two connecting grooves 206 are movably fitted on the outside of the oil seal 207. The oil seal 207 is movably fitted on the outside of the rotating shaft of the sorting cylinder 104. The sealing grooves 204 can install the sealing ring 205, and the connecting grooves 206 can seal the oil seal 207, so that the sealing ring 205 and the oil seal 207 can stably seal the gap between the first fixing frame 201 and the second fixing frame 202 and the rotating shaft of the sorting cylinder 104.

[0035] In order to ensure that the sealing sleeve 208 can stably seal the connection between the sorting cylinder 104 and the fixed housing 101, such as Figure 2 and Figure 5-6 As shown, a fixing groove 106 is provided on the outer wall of the fixed housing 101 on the side away from the mounting groove 105. The inner wall of the fixing groove 106 is movably connected to the sealing sleeve 208. The sealing sleeve 208 is movably sleeved on the outside of the rotating shaft of the sorting cylinder 104.

[0036] The specific implementation scenario is as follows: During the dry powder sorting process, the first fixing frame 201 is fitted onto the outer wall of one side of the rotating shaft of the sorting cylinder 104. Then, the sealing ring 205 is fitted onto the outside of the rotating shaft and placed within the sealing groove 204 on the inner wall of the first fixing frame 201. Next, the second fixing frame 202 is fitted onto the outside of the rotating shaft so that the sealing groove 204 on its inner wall can fit onto the outer side of the end of the sealing ring 205 away from the first fixing frame 201, allowing the first fixing frame 201 and the second fixing frame 202 to be tightly joined. Then, the sorting cylinder 104 is installed inside the fixed housing 101, allowing the rotating shaft of the sorting cylinder 104 to be inserted into the fixed housing. The hole in the middle of the inner wall of the fixed groove 106 allows the first fixed frame 201 and the second fixed frame 202 to be installed into the mounting groove 105. Then, the connecting bolt 203 passes through the first fixed frame 201 and the second fixed frame 202 and is threaded to the inner wall of the mounting groove 105, so that the first fixed frame 201 and the second fixed frame 202 can be installed and fixed. Then, the oil seal 207 is sleeved on the outside of the rotating shaft so that it can be located on the inner wall of the connecting groove 206. The gap between the first fixed frame 201 and the second fixed frame 202 and the rotating shaft of the sorting cylinder 104 can be sealed by the sealing ring 205 and the oil seal 207.

[0037] Then, the sealing sleeve 208 is fitted onto the outer wall of the side of the rotating shaft of the sorting cylinder 104 away from the first fixed frame 201, so that the sealing sleeve 208 can be inserted into the inner wall of the fixed groove 106. Then, the fastening bolt 209 is used to pass through the sealing sleeve 208 and threadedly connected to the inner wall of the fixed groove 106, so that the sealing sleeve 208 can stably seal the gap between the sorting cylinder 104 and the fixed housing 101, thereby keeping the sorting cylinder 104 stable during rotation. This can prevent dry powder from entering the gap between the sorting cylinder 104 and the device, increasing the wear between the sorting cylinder 104 and the device, and thus extending the service life of the sorting cylinder 104 and the device. This embodiment specifically solves the problem in the prior art that dry powder can easily enter the gap between the sorting cylinder 104 and the device, affecting the stability of the rotation of the sorting cylinder 104 and increasing the wear between the sorting cylinder 104 and the device.

[0038] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
