Description

Technical Field

[0001] The utility model relates to the technical field of sealers, in particular to a novel energy-saving rotary sealer. Background Art

[0002] Soft packing seal and mechanical seal are two common sealing methods for rotating shafts. Soft packing seal is a compression seal that fills the annular gap. It usually uses cotton, linen and other fibers to fill the gap between the rotating shaft and the packing cavity to prevent medium leakage. This method has a simple sealing structure, low cost, and easy disassembly and assembly. However, it is easy to wear, has poor sealing effect, and has a short service life under high pressure and high speed, especially under working conditions where the fluid medium contains solid particles.

[0003] A Chinese patent discloses an energy-saving rotary sealer (authorization announcement number CN203730760U). The patent technology discloses an energy-saving rotary sealer, including a stuffing box, a stuffing box gland, a stuffing and a rotary sealing grinding disc. The stuffing box is open at both ends and hollow inside. It is connected to the stuffing box gland. The stuffing is located in the stuffing box cavity; the rotary sealing grinding disc is close to one end of the stuffing. The stuffing box gland presses the two rotary sealing grinding discs to the end of the rotating shaft through the stuffing, so that the two rotary sealing grinding discs form a contact seal. Under the action of the fluid medium and the elasticity of the stuffing, the end faces of the two sealing grinding discs are close to each other and rotate relative to each other, thereby achieving the sealing requirements. The device combines the packing seal with the mechanical seal for installation, and has a simple structure, is easy to use, and has high sealing performance. This patented technology solves the problem that mechanical seals are the most commonly used sealing method for shaft seals in industry today. Under the action of fluid media and elastic elements, two sealing end faces perpendicular to the axis rotate closely together to achieve a sealing effect. This method can work under high temperature, high pressure and corrosive conditions. It has reliable sealing, small leakage and long service life, but its structure is complex, loading and unloading is inconvenient and the cost is high.

[0004] However, in the prior art, when replacing the grinding disc built into the rotary sealer, the packing needs to be completely disassembled to replace the grinding disc, and the problem of facilitating the replacement of the grinding disc in the prior art needs to be solved.

[0005] Therefore, those skilled in the art provide a novel energy-saving rotary sealer to solve the problems raised in the above background technology. Utility Model Content

This design helps to detect and handle leakage problems in time, avoiding equipment damage and production interruption. Description of the Drawings

A positioning cylinder 9 is hermetically sleeved and installed outside the positioning shaft 3. A sealing ring cylinder 10 is integrally fixed on the inner wall of the positioning cylinder 9. The positioning cylinder 9 is inserted into the sealing groove 8 through the sealing ring cylinder 10 and is hermetically installed on the positioning shaft 3;

[0031] A leak-proof detection structure 21 for real-time detection of water leakage is installed at the connection between the rotating shaft 1 and the positioning shaft 3. An installation member II 13 is integrally fixed on the outer wall of the positioning shaft 3, and a corresponding installation member I 12 is integrally fixed on the outer wall of the positioning cylinder 9 with respect to the installation member II 13.

[0032] A sealing gasket 14 is hermetically provided between the installation member I 12 and the installation member II 13, and the installation member I 12 and the installation member II 13 are locked and installed through external bolts. A grinding disc 4 is detachably installed at one end of the rotating shaft 1, and a flange member 2 is fixedly assembled at the other end of the rotating shaft 1. The rotating shaft 1 is rotatably arranged inside the positioning shaft 3 through the grinding disc 4, and a grinding disc I 5 is detachably installed on the grinding disc 4, and a grinding disc II 6 slides on one side of the grinding disc I 5.

[0033] A packing box 15 in the shape of a ring cylinder is detachably installed outside the grinding disc II 6. The packing box 15 is detachably installed between the rotating shaft 1 and the positioning shaft 3, and a locking disc 7 detachably installed on the positioning shaft 3 is provided on one side of the packing box 15.

[0034] An air and material pipe 11 is integrally fixed at the center of the positioning cylinder 9. The leak-proof detection structure 21 includes a sealing top cover 2101 and a sealing bottom cover 2102. Installation outer frames 2103 are fixed on the outer walls between the sealing top cover 2101 and the sealing bottom cover 2102, and the sealing top cover 2101 and the sealing bottom cover 2102 are locked and fixed through the installation outer frames 2103 using external bolts;

[0035] At the center of one side of the sealed top cover 2101 and the sealed bottom cover 2102, an arc-shaped shaft 2104 is integrally fixed. An annular shaft member 2105 is rotatably and sealed inside the arc-shaped shaft 2104, and the annular shaft member 2105 is sealed and sleeved on the outer wall of the rotating shaft 1.
