Description

Technical Field

[0001] This utility model relates to the field of enamel-lined autoclave mechanical seal technology, and in particular to a pressure-bearing mechanical seal. Background Technology

[0002] Enameled reactors are composite material products made by lining the inner surface of a steel container with high-silica glass, which is then firmly bonded to the metal surface through high-temperature firing. Mechanical seals, also known as mechanical seals in the industry, are devices used to seal the connection between a rotating shaft and the machine body. Typical mechanical seals include a shaft sleeve, stationary ring, and rotating ring, making them widely used in enamel-lined reactors.

[0003] Chinese Patent No. CN208885601U discloses a high-pressure-bearing mechanical seal, including a bushing fitted on a pump shaft. A spring seat, a transmission ring, a moving ring assembly, and a stationary ring are sequentially fitted around the bushing. A pressure cap is also included, secured by a limiting block and a cylindrical head screw. A transmission screw extending into the transmission ring is located within the spring seat. A spring is also included, with one end fixed within the spring seat and the other end abutting against the transmission ring. A transmission pin is also included, with one end extending into the pressure cap and the other end extending into the stationary ring. The transmission ring and the moving ring assembly are plug-in type. This invention, by changing the transmission ring and moving ring assembly to a plug-in structure, makes the mechanical seal more robust and increases its pressure-bearing capacity from the original 4MPa to 6MPa, thus broadening the application range of this mechanical seal structure.

[0004] Existing mechanical seal structures use bolt connections, which can lead to bolt slippage and instability during use. This affects the sealing performance between mechanical seal components, reduces the pressure-bearing capacity of the mechanical seal, and can also cause overheating and deformation during use, resulting in dust and material leakage from enamel-lined reactors, thus reducing the reliability of the mechanical seal structure.

[0016] Preferably, the cooling assembly further includes a cooling shell connected to the lower bushing, and the cooling shell is provided with a circular opening b for the mechanical seal body to pass through and connect to the enamel-lined reactor.

By reinforcing component 2 and connecting it to the main body 1 of the mechanical seal, a mechanical seal structure can be easily added, improving the pressure-bearing capacity of the mechanical seal and preventing dust and material leakage from the enamel-lined reactor. The cooling component 3 facilitates cooling of the pressure-bearing mechanical seal structure, preventing overheating and deformation, further reducing leakage and improving the reliability of the pressure-bearing mechanical seal structure. The telescopic rod 203 includes a sliding rod, a sliding part, a fixed cylinder, and a spring. One end of the sliding rod is hinged to the interior of the lower support plate 204, and the other end slides into the fixed cylinder and connects to the sliding part. The sliding part slides to the inner wall of the fixed cylinder. The spring is located inside the fixed cylinder and sleeved on the outside of the sliding rod, with both ends connected to the inner wall of the fixed cylinder and the sliding part, respectively. The fixed cylinder connects to the interior of the upper support plate 201 for use with the pressure-bearing mechanical seal.

[0027] Further explanation: The cooling assembly 3 includes an upper cooling shell 301 connected to the upper bushing 101, with an injection pipe 302 connected to it. The injection pipe 302 is movably connected to a sealed cover 303. The upper cooling shell 301 has a circular opening a for the mechanical seal body 1 to pass through and connect to the enamel-lined reactor, and the output end of the injection pipe 302 communicates with the interior of the upper cooling shell 301. The cooling assembly 3 also includes a lower cooling shell 304 connected to the lower bushing 102, with a circular opening b for the mechanical seal body to pass through and connect to the enamel-lined reactor. The lower cooling shell 304 and the upper cooling shell 301 are connected to the injection pipe 302 and the cover 303. By opening the cover 303, cold water is injected into the lower cooling shell 304 and the upper cooling shell 301, conveniently achieving a cooling effect, conveniently improving the functionality of the pressure-bearing mechanical seal, and further enhancing the practicality of the pressure-bearing mechanical seal.

[0028] Example 2

[0029] like Figure 1 - Figure 3 As shown, this utility model proposes a pressure-bearing mechanical seal. Based on the above embodiments, this embodiment also details the specific components of the mechanical seal body 1 and the reinforcing component 2, as well as their mating methods.

[0030] To further explain, the mechanical seal body 1 is connected to an upper bushing 101 and a lower bushing 102; both the upper bushing 101 and the lower bushing 102 are provided with mounting holes for connecting the reinforcing component 2. Both the upper bushing 101 and the lower bushing 102 are provided with grooves, which are opposite each other and respectively connect to the moving ring and the stationary ring, so that the assembled upper and lower mechanical seals are connected, and finally the mechanical seal is installed and tightened to form the structure, so that the mechanical seal body 1 can be assembled and connected for use on the enamel-lined reactor.

[0031] Further explanation: Mounting block a202 is connected to the upper bushing 101 and is detachably connected; base 205 is connected to mounting block b, which is connected to the lower bushing 102 and is detachably connected; lower support plate 204 is movably connected inside the upper support plate 201, and the upper support plate 201 and lower support plate 204 are movably connected to the periphery of the mechanical seal body 1. By using bolts through the through holes in mounting block a202 and upper bushing 101, the upper support plate 201 and upper bushing 101 are connected; by using bolts through the through holes in mounting block b and lower bushing 102, the lower support plate 204 and lower bushing 102 are connected. This facilitates the connection of the reinforcing component 2 and the mechanical seal body 1, making the operation simple and easy to use.

[0032] The working principle of this utility model is as follows: During use, the mechanical seal body 1 is adjusted by pulling out the lower support plate 204. The lower support plate 204 drives the telescopic rod 203 to extend and retract within the upper support plate 201 for adjustment. The adjustment range of the lower support plate 204 and the upper support plate 201 is large enough to connect the mounting block a202 and the upper bushing 101. The lower support plate 204 is connected to the lower bushing 102 and extends and retracts to the inside of the upper support plate 201 according to the height of the mechanical seal body 1. After adjustment, the lower support plate 204 and the lower bushing 102 are connected with bolts. The reinforcing component 2 is provided with four parts, all connected to the periphery of the mechanical seal body 1 through the upper bushing 101 and the lower bushing 102, thereby increasing the structural composition of the mechanical seal body 1. The upper support plate 201 and the lower support plate 204 are connected by the telescopic rod 203 for easy synchronization. The pressure-bearing mechanical seal is used to improve its pressure-bearing capacity and prevent dust and material leakage from enamel-lined reactors. During installation, the upper cooling shell 301 and lower cooling shell 304 are connected to the upper shaft sleeve 101 and lower shaft sleeve 102, respectively, according to usage requirements. The upper cooling shell 301 and lower cooling shell 304 are connected to the injection pipe 302, which in turn connects to the cover 303. Operators open the cover 303 and inject cold water into the upper cooling shell 301 and lower cooling shell 304 through the injection pipe 302. The upper cooling shell 301 and lower cooling shell 304 cool the pressure-bearing mechanical seal, preventing overheating and deformation, further avoiding leakage, and conveniently improving the reliability of the pressure-bearing mechanical seal structure.
