Abstract
Description
Technical Field
[0001] This utility model relates to the field of cylinder sealing technology, and in particular to a sealing structure for dust control in cylinder gaps. Background Technology
[0002] In cement plants, cylinders are often used to drive conveying devices to transport materials, thereby ensuring that materials flow between different equipment and storage areas according to the production plan.
[0003] In existing cylinders, the piston and connecting rod running parts are sealed, while the piston's external running parts are exposed. When the cylinder operates, the air in the cylinder mounting area and running gap is agitated. Because the piston running parts are exposed, dust particles, lubricating oil mist, or other impurities will be stirred up by the airflow. Therefore, a certain amount of dust will be generated in the cylinder mounting area and running gap, making it difficult to maintain the hygiene of the equipment on site. Long-term accumulation of dust is significant, which is not conducive to on-site clean management and causes air pollution. Therefore, based on the above situation, it is necessary to design a sealing structure for dust control in cylinder gaps to solve the above problems. Utility Model Content

The fixed end of the cylinder body is detachably connected to a docking ring, and the docking ring is provided with an isolation cloth sleeve. The isolation cloth sleeve is used to isolate the movable end of the cylinder body from the external environment. A transparent sealing plate is provided at the end of the isolation cloth sleeve away from the docking ring. The middle part of the transparent sealing plate is detachably connected to the movable end of the cylinder body. The support member is located between the transparent sealing plate and the docking ring. The support member is located inside the isolation cloth sleeve to support the isolation cloth sleeve and can deform with the movement of the movable end of the cylinder body.
[0007] Preferably, the support member is a corrugated hose, and the support member has multiple vent holes.
[0008] Preferably, the support member is a plurality of elastic strips protruding toward the direction of the isolation cloth cover, and the plurality of elastic strips are equidistantly arranged along the central axis of the movable end of the cylinder body.
[0009] Preferably, a rotating ring is rotatably connected to the middle of the transparent sealing plate, and a fixed ring is provided at the movable end of the cylinder body, with the rotating ring and the fixed ring being threadedly connected.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.
[0021] Reference Figures 1-5 As shown, a sealing structure for dust control in cylinder gaps is described. In the prior art, the cylinder body 1 includes a cylinder barrel 101 located at the fixed end of the cylinder body 1, a front end cover 102 connected to the front end of the cylinder barrel 101, and a rear end cover 103 connected to the rear end of the cylinder barrel 101. The front end cover 102 and the rear end cover 103 seal the cylinder barrel 101. A piston rod 104 is slidably connected inside the cylinder barrel 101. When the cylinder body 1 starts, the cylinder barrel 101 exits the fixed end of the cylinder body 1, while the portion of the piston rod 104 that moves outside the cylinder barrel 101 is the movable end of the cylinder body 1. During use, the piston rod 104 continuously extends and retracts inside the cylinder barrel 101. When the cylinder body 1 is used in dusty environments such as cement plants, the extension and retraction of the piston rod 104 and the movement gap between the cylinder barrel 101 generate dust, making it difficult to maintain the cleanliness of the cylinder body 1. Long-term accumulation of dust is significant, hindering on-site clean management and causing air pollution. To address these problems, a new design is proposed. Figures 1-5 As shown, this utility model makes the following improvements: a docking ring 2 is detachably connected to the fixed end of the cylinder body 1 via a snap-fit or fixing strap. An isolation cloth sleeve 3 is provided on the docking ring 2, which covers the movable end of the cylinder body 1 and isolates it from the external environment. The isolation cloth sleeve 3 can be made of dustproof and breathable materials such as polytetrafluoroethylene microporous film composite fabric or high-performance textile composite fabric. A transparent sealing plate 4 is provided at the end of the isolation cloth sleeve 3 away from the docking ring 2. The isolation cloth sleeve 3 is sealed by the transparent sealing plate 4, and the operating status of the piston rod 104 can be observed through the transparent sealing plate 4. The middle part of the transparent sealing plate 4 is detachably connected to the movable end of the cylinder body 1. After a period of use, the isolation cloth sleeve 3 can be removed for inspection and replacement, improving the flexibility of the isolation cloth sleeve 3. At the same time, when the isolated piston rod 104 moves in extension and retraction, it can drive the transparent sealing plate 4 to move, so that the piston rod 104 is always in a closed state, reducing the movement gap between it and the cylinder 101 and generating a certain amount of dust.
[0022] Furthermore, when the piston rod 104 reciprocates, a support member 5 is provided between the transparent sealing plate 4 and the docking ring 2. The support member 5 is located inside the isolation cloth sleeve 3 to support the isolation cloth sleeve 3 and can deform with the movement of the moving end of the cylinder body 1. The support member 5 supports the isolation cloth sleeve 3 to prevent the isolation cloth sleeve 3 from contacting the piston rod 104, which would cause the piston rod 104 to get stuck between the isolation cloth sleeve 3 and the cylinder barrel 101 and affect the use of the cylinder body 1. At the same time, it can also keep the piston rod 104 in a closed state to reduce dust.
[0023] The first embodiment provided by this utility model, with reference to... Figures 2-3As shown, the support member 5 is a corrugated hose made of rubber. The corrugated hose is foldable and can change its extension and retraction shape with the piston rod 104. At the same time, the support member 5 is provided with multiple vent holes 6. When the piston rod 104 causes the corrugated hose to extend, air can enter the corrugated hose through the vent holes 6. When the piston rod 104 causes the corrugated hose to retract, air can leave the corrugated hose through the vent holes 6, thereby ensuring the normal extension and retraction of the corrugated hose and better supporting the isolation cloth cover 3.
[0024] The second embodiment provided by this utility model, with reference to... Figures 4-5 As shown, the support member 5 consists of multiple arc-shaped elastic strips protruding towards the isolation cloth sleeve 3. The elastic strips can be made of materials such as rubber or silicone. The multiple elastic strips are equidistantly arranged along the central axis of the moving end of the cylinder body 1 and located on the outer periphery of the piston rod 104 to support the isolation cloth sleeve 3 as a whole, thereby preventing the isolation cloth sleeve 3 from contacting the piston rod 104.
[0025] Reference Figures 1-5 As shown, a rotating ring 7 is rotatably connected to the middle of the transparent sealing plate 4, and a fixed ring 8 is provided at the movable end of the cylinder body 1. The rotating ring 7 is threadedly connected to the fixed ring 8. When it is necessary to inspect or replace the piston rod 104 or replace the isolation cloth sleeve 3, the rotating ring 7 can be rotated to unscrew the rotating ring 7 from the fixed ring 8. At the same time, the connecting ring 2 is disassembled from the cylinder 101, so that the piston rod 104 can be exposed for inspection and maintenance, and the isolation cloth sleeve 3 can be replaced.
[0026] Reference Figure 2 As shown, further, a storage component 9 is provided on the outer wall of the docking ring 2. When the movable end of the cylinder body 1 is in a retracted state, the isolation cloth sleeve 3 is located inside the storage component 9. Under normal circumstances, after the cylinder body 1 is used up, the piston rod 104 will retract into the cylinder barrel 101. At this time, the piston rod 104 drives the isolation cloth sleeve 3 and the support component 5 to be compressed, so that the isolation cloth sleeve 3 is located inside the storage component 9, which can effectively protect the isolation cloth sleeve 3 and extend the service life of the isolation cloth sleeve 3.
[0027] Reference Figure 2 As shown, furthermore, an activated carbon adsorption layer 10 is provided on the inner wall of the isolation cloth sleeve 3. The activated carbon adsorption layer 10 is provided inside the isolation cloth sleeve 3. The activated carbon adsorption layer 10 on the inner wall of the isolation cloth sleeve 3 can effectively adsorb various impurities that enter the isolation cloth sleeve 3. Since the working environment of the cylinder body 1 may contain pollutants such as dust, oil, and chemical gases, when the piston rod 104 moves, these impurities may enter the isolation cloth sleeve 3 with the air flow. The activated carbon adsorption layer 10 has a highly developed pore structure, which can adsorb dust particles, oil molecules and harmful gases, prevent them from entering the cylinder and reduce damage to the internal components of the cylinder.
