Description

Technical Field

[0001] The utility model relates to the technical field of electric bag composite dust collectors, in particular to a novel transmission sealing device for horizontal electric bag composite dust collectors. Background Art

[0002] With the development of industry and the increasing demand for environmental quality, electric bag composite horizontal dust collectors have been widely used in industrial production. The back-blowing and dust cleaning drive system of electric bag composite horizontal dust collectors plays a crucial role. This system includes a back-blowing blower, back-blowing duct, pulsation valve, blower box, and transmission mechanism. The back-blowing airflow uses the clean air after dust removal from the dust collector. It draws air from the exhaust flue of the smoke box. After the back-blowing blower is activated, the airflow enters the back-blowing duct, passes through the pulsation valve, and is transmitted to the movable air box inside the dust collector. The transmission mechanism then moves the blower box horizontally to blow and clean the bags in sequence.

[0003] However, the current transmission mechanism in this system, consisting of a wire rope, transmission seal, roller, and guide pulley, presents numerous practical challenges. First, the seal is not tightly sealed, allowing for excessive air leakage, which can easily cause the temperature inside the equipment to drop too low. Second, during operation, the wire rope rubs against the insulator in the seal, increasing the ground resistance of the dust collector housing. Third, the dust inside the dust collector housing is hot, while the outside is room temperature, resulting in a significant temperature difference. During intermittent periods of wire rope operation, cold and hot air converge, and condensation easily forms on the wire rope in the sealing device, forming acidic corrosive droplets that settle on the surface of the wire rope, corroding it and causing strand breakage. This in turn causes the transmission system to fail and the equipment to shut down. Fourthly, the dust collector operates at negative pressure, and external cold air enters the housing through the gap between the sealing device and the wire rope. The internal hot gas intersects with this air, and the acidic corrosive droplets in the sealing device combine with the dust, causing dust to compact in the holes of the sealing device, blocking the holes and increasing the resistance of the transmission system, affecting the operation of the equipment. Fifthly, the wire rope moves axially during operation. Due to vibration during operation, the wire rope moves radially, enlarging the holes in the sealing device and increasing air leakage. These problems seriously affect the normal operation and service life of the electric bag composite horizontal dust collector and need to be solved urgently. Utility Model Content

[0004] The purpose of the utility model is to provide a novel transmission sealing device for a horizontal electric bag composite dust collector to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution, which includes a sealing box, a mounting groove is provided on one side of the sealing box, a socket communicated with the mounting groove is provided on the other side of the sealing box, an insulator is provided in the mounting groove, a graphite sleeve is provided in the insulator, a retaining rack is provided in the mounting groove, the retaining rack is located at the tail of the insulator, a plurality of threaded holes are provided at the tail of the sealing box, a felt is provided at the tail of the sealing box, the felt is provided with through holes at the positions corresponding to the plurality of threaded holes, a bolt is provided in each of the threaded holes, and the bolt is abutted against the felt.

[0006] As a preferred embodiment of the present invention, the graphite sleeve is provided with a fourth socket at a position corresponding to the first socket, the retaining frame is provided with a second socket at a position corresponding to the fourth socket, and the felt is provided with a third socket at a position corresponding to the second socket.

[0007] As a preferred embodiment of the present invention, a pair of sealing rings are provided in the first insertion hole.

[0008] As a preferred embodiment of the present invention, the steel wire rope is passed through the sealing ring, the second plug hole, the third plug hole and the fourth plug hole.

[0009] Compared with the prior art, the above technical solution of the present invention has the following beneficial technical effects:

[0010] The sealing ring and retaining frame added in the utility model can effectively limit the radial displacement of the wire rope during operation. During the operation of the equipment, the wire rope often shakes or deflects due to various factors. The presence of the sealing ring and retaining frame can stabilize the wire rope on the established operating track, greatly reducing its unnecessary movement. In this way, the friction between the wire rope and the holes in the sealing device is greatly reduced, and the wear is also reduced. The reduction in wear not only extends the service life of the sealing device, but also effectively prevents air leakage caused by wear of the holes, ensuring that the sealing performance of the equipment is maintained in good condition.

[0011] A felt is added to one end of the utility model, which is resistant to high temperatures and has good sealing properties. The material is high-density PPS. This material has excellent high-temperature resistance and can maintain stable physical and chemical properties under high-temperature environments. On the one hand, it can reduce the temperature difference in the sealing device, making the temperature inside the sealing device more uniform; under some working conditions, excessive temperature difference will lead to condensation, and condensation will cause corrosion problems, which will damage the sealing device. The use of high-density PPS sealing felt can effectively reduce the risk of condensation, thereby reducing the decline in sealing performance and air leakage caused by corrosion. On the other hand, the sealing felt itself has good sealing properties, which can further reduce air leakage and improve the overall operating efficiency of the equipment.

[0012] The addition of a graphite body in the present invention has multiple advantages. First, graphite has a self-lubricating effect. When the wire rope runs in the sealing device, the graphite body can greatly reduce the running resistance, making the equipment run more smoothly and reducing energy consumption. Secondly, the graphite body is in direct contact with the wire rope, avoiding damage to the insulator by the wire rope. The insulator plays an important electrical insulation role in the sealing device. Once damaged, it may cause electrical failure and affect the normal operation of the equipment. Through the isolation protection of the graphite body, the service life of the insulator is extended, and the reliability and safety of the equipment are also effectively improved.
