Description

Technical Field

[0001] This utility model relates to the technical field of shaft sealing devices, and in particular to an odor-proof sealing device for the shaft end of a grate cooler fan. Background Technology

[0002] The grate cooler fan is a key piece of equipment in the cement production line. It is mainly used to cool the high-temperature clinker inside the grate cooler and to provide secondary air for combustion in the kiln.

[0003] Existing anti-odor sealing devices for the fan shaft end of grate coolers generally adopt a packing seal structure. The core principle is to fill multiple sets of flexible sealing materials layer by layer inside the sealing cavity, and use the pre-tightening force of the gland to make the flexible materials form a tight contact interface with the shaft surface, thereby blocking the leakage path of high-temperature gas containing dust and odor. At the same time, the material's own elasticity absorbs shaft vibration, and the extremely thin liquid film formed by the micro-leakage of the medium achieves self-lubrication. However, the frequent shaft friction of the flexible sealing materials causes wear, resulting in gaps between the multiple sets of flexible sealing materials, which in turn leads to a deterioration in the sealing effect. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an odor-proof sealing device for the fan shaft end of a grate cooler.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An odor-proof sealing device for the shaft end of a grate cooler includes a fan, a cylinder connected to the fan housing, a portion of the fan shaft located within the cylinder, two sets of arc-shaped plates inserted into one end of the cylinder, blocks connected to one end of each set of arc-shaped plates, one end of the cylinder, and the other end of each set of blocks, each set of blocks having a hole, some of the holes being threadedly connected to bolts, the two sets of bolts being threadedly connected to corresponding holes, and multiple sets of springs connected to one end of each set of arc-shaped plates, the multiple sets of springs being connected to two sets of arc-shaped plates.

[0007] Preferably, both sets of the arc-shaped plates are connected to a plate body at one end and the other end, and each set of the plate body has two sets of holes, some of which are threaded with bolts, and the bolts are threaded to the corresponding holes.

[0008] Preferably, each of the two sets of bolts has a knob connected to one end.

[0009] Preferably, both sets of arc-shaped plates are connected to multiple sets of rods, and multiple sets of springs are respectively sleeved on the outer wall of the corresponding rods. Both sets of arc-shaped plates have a hole at one end, and the multiple sets of rods are respectively inserted into the corresponding hole.

[0010] Preferably, both one end of the cylinder and the other end are provided with holes, and each of the two sets of arc-shaped plates is connected to a column, with the two sets of columns inserted into the corresponding holes.

[0011] Preferably, each of the multiple sets of bolts has a knob connected to one end.

[0012] Preferably, a flexible sealing material can be placed inside the cylinder, and the flexible sealing material can be packing with graphite fiber as the base material.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Through the cooperation between the spring, arc plate two, and arc plate one, during the long-term operation of the grate cooler fan, the shaft end and the flexible sealing material inevitably experience material wear due to high-frequency friction. As the wear of the flexible sealing material accumulates, the gaps between the layers gradually increase, eventually leading to increased leakage of odorous gases. At this time, the spring connected to one end of arc plate one will drive arc plate two to move, thereby applying pressure to the flexible sealing material and causing multiple sets of flexible sealing materials to adhere tightly. This, to a certain extent, avoids the problem of poor sealing effect caused by gaps due to wear of the flexible sealing material.

[0015] 2. By using the connection between bolt 2, bolt 1 and the cylinder, unscrew bolt 1 to disconnect the cylinder from the arc plate 1, then unscrew bolt 2 to disconnect the two sets of arc plates 1, and remove arc plate 1. This allows the flexible sealing material inside the cylinder to be replaced. To a certain extent, the operation of replacing the flexible sealing material is relatively simple and improves efficiency. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1, referring to Figures 1 to 5 A odor-proof sealing device for the shaft end of a grate cooler fan includes a fan 1, which consists of a geared motor, a main shaft, a housing, and a worktable. The geared motor is mounted on the worktable, and its output end is connected to the main shaft. The housing is connected to one end of the worktable, and the main shaft is rotatably connected to the housing. An impeller is located inside the housing and connected to the main shaft. The fan 1 is existing technology and will not be described in detail here. The model of the fan 1 can be selected according to actual conditions. A cylinder 2 is connected to the housing of the fan 1, and part of the fan 1's shaft is located inside the cylinder 2. Multiple sets of flexible sealing materials are filled layer by layer inside the cylinder 2. The pressure of the flexible materials on the arc-shaped plate 9 creates a tight contact interface between the flexible materials and the shaft surface, thereby blocking the leakage path of high-temperature gas containing dust and odors. Two sets of arc-shaped plates 3 are inserted into one end of the cylinder 2. The arc-shaped plates 3 are stepped, with the smaller diameter end facilitating insertion into the cylinder 2 and the larger diameter end connecting to the cylinder. The end faces of body 2 are in contact. One end of each of the two sets of arc-shaped plates 3 and one end of the cylinder 2 are connected to a block 4. By screwing bolts 6 into the corresponding holes 5, the cylinder 2 can be connected to the arc-shaped plates 3. Repeating the above operation in the opposite direction can separate the arc-shaped plates 3 from the cylinder 2. Each set of blocks 4 has a hole 5. Some holes 5 are threaded with bolts 6. Two sets of bolts 6 are threaded to the corresponding holes 5. Each of the two sets of arc-shaped plates 3 is connected to a set of springs 8. The springs 8 are connected to two sets of arc-shaped plates 9. The springs 8 apply a force to the arc-shaped plates 9 to move them away from the arc-shaped plates 3. When the flexible sealing material is damaged by friction with the shaft and there are gaps between the flexible sealing materials, the arc-shaped plates 9 press the multiple sets of flexible sealing materials together, which to a certain extent prevents the gas from escaping from the gaps between the flexible sealing materials and improves the sealing performance to a certain extent.

[0024] In this embodiment, each of the two sets of arc-shaped plates 3 is connected to a plate body 14 at one end and the other end. Each set of plate bodies 14 has two sets of holes 15, some of which are threaded with bolts 16. The bolts 16 are threaded into their corresponding holes 15. Unscrewing the bolts 16 disconnects the connection between the two sets of arc-shaped plates 3, allowing for separation and facilitating subsequent replacement of the flexible sealing material, thus improving efficiency to some extent. Each of the two sets of bolts 6 has a knob 7 at one end, making it easier to rotate the bolts 6. Each of the two sets of arc-shaped plates 9 is connected to multiple rods 10, with multiple springs 8 respectively fitted onto the outer wall of the corresponding rods 10. Each of the two sets of arc-shaped plates 3 has a hole 11 at one end, with the rods 10 inserted into their corresponding holes 11. The rods 10 guide the movement of the arc-shaped plates 9. Both ends of the cylinder 2 have holes 12. Two sets of arc-shaped plates 3 are each connected to a column 13 at one end. The columns 13 are inserted into the corresponding holes 12, providing guidance for the installation of the arc-shaped plates 3. Multiple sets of bolts 16 are each connected to a knob 17 at one end, allowing for easier rotation of the bolts 16. Flexible sealing material can be placed inside the cylinder 2. The flexible sealing material can be made of packing with graphite fiber as the base material. Graphite fiber has high-temperature resistance, suitable for the high-temperature environment of the grate cooler. The structure is dense, preventing dust intrusion and providing strong wear resistance.

[0025] The working principle of this embodiment is as follows: During use, multiple sets of flexible sealing materials are filled layer by layer inside the cylinder 2. The pressure of the arc-shaped plate 9 on the flexible material makes the flexible material form a tight contact interface with the shaft surface, thereby blocking the leakage path of high-temperature gas containing dust and odor. When the flexible material wears itself due to high-frequency friction with the shaft, and there are gaps between it and the adjacent flexible sealing materials, the arc-shaped plate 9 applies pressure to the flexible sealing material under the action of the spring 8, pressing the multiple sets of flexible sealing materials together. This prevents the high-temperature gas containing dust and odor from possibly escaping from the gaps, thus improving the sealing performance to a certain extent. After working for a long time, the bolt 6 is unscrewed to disconnect the connection between the two sets of arc-shaped plates 3 and the cylinder 2. Then, the bolt 16 is unscrewed to disconnect the connection between the two sets of arc-shaped plates 3. The two sets of arc-shaped plates 3 are then separated, and the severely worn flexible sealing material inside the cylinder 2 can be replaced with a tool. The replacement operation is relatively simple and improves efficiency to a certain extent.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
