Description

Technical Field

[0001] The utility model belongs to the technical field of vacuum compressors, in particular to a corrosion-resistant liquid ring vacuum compressor. Background Art

[0002] A liquid ring compressor is a type of compressor. Its principle is that the impeller is eccentrically arranged in the cylinder, and a certain amount of water or other liquid is introduced into the cylinder. The rotation of the impeller offset in the cylinder causes the volume of the crescent cavity formed by the liquid ring attached to the inner wall of the cylinder and the impeller to change, so as to compress and transport the gas. When the exhaust pressure of the liquid ring compressor is lower than 0.2 MPa, it is called a liquid ring blower. At the same time, in order to ensure that the vacuum compressor can be suitable for liquid environments in different states, the existing vacuum compressors all have a certain corrosion resistance function.

[0003] However, after the existing vacuum compressor is transported to a specific location, it is necessary to connect the vacuum compressor to the pipeline of the external equipment. Since the vacuum compressor cannot be controlled to be in the best installation position each time it is transported, the position of the vacuum compressor needs to be adjusted each time the pipeline is installed. However, the existing vacuum compressor is too large and too heavy, so when adjusting the position, multiple workers are required to work synchronously, which increases the labor intensity and may cause injuries to people during the adjustment process. At the same time, each time the position is adjusted, due to the large friction between the structures, the structure is extremely susceptible to wear during the adjustment process, which makes the structure easy to be damaged. To this end, we provide a corrosion-resistant liquid ring vacuum compressor to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a corrosion-resistant liquid ring vacuum compressor, which can disengage the tooth opening from the tooth plate by moving the sleeve column, thereby facilitating the position adjustment of the compressor body. At the same time, the ball block is set and used to improve the adjustment efficiency of the compressor body and reduce the probability of structural friction damage.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model discloses a corrosion-resistant liquid ring vacuum compressor, comprising a compressor body; an assembly plate is fixed on the lower end surface of the compressor body, a mounting plate is arranged directly below the assembly plate, a tooth plate is fixed on the middle part of the lower end surface of the assembly plate, a sleeve plate is fixed on the lower end surface of the tooth plate, a round block is fixed on the middle part of the upper end surface of the mounting plate, a plurality of ball openings are arranged evenly in an annular shape on the upper end surface of the round block, ball blocks are rotatably arranged inside the ball openings, sleeve columns are arranged at positions between the assembly plate and the mounting plate, and a tooth opening meshing with the tooth plate is arranged in the middle part of the upper end surface of the sleeve column.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0028] See also Figure 1-5 The utility model is a corrosion-resistant liquid ring vacuum compressor. By moving the sleeve 4, the tooth mouth 401 is disconnected from the tooth plate 201, so as to facilitate the position adjustment of the compressor body 1. At the same time, the setting of the ball block 305 is used to improve the adjustment efficiency of the compressor body 1 and reduce the probability of structural friction damage.

[0029] Specifically, a compressor body 1; an assembly plate 2 is fixed to the lower end surface of the compressor body 1, a mounting plate 3 is arranged directly below the assembly plate 2, a tooth plate 201 is fixed to the middle of the lower end surface of the assembly plate 2, a sleeve plate 202 is fixed to the lower end surface of the tooth plate 201, a round block 301 is fixed to the middle of the upper end surface of the mounting plate 3, a plurality of ball openings 302 are arranged evenly distributed in an annular shape on the upper end surface of the round block 301, ball blocks 305 are rotatably arranged inside the ball openings 302, sleeve columns 4 are arranged at positions between the assembly plate 2 and the mounting plate 3, and a tooth opening 401 engaged with the tooth plate 201 is arranged in the middle of the upper end surface of the sleeve column 4.

[0030] The operation process of this embodiment is as follows: through the use of the above-mentioned structure, when the compressor body 1 needs to be rotated, the sleeve column 4 can be moved downward, thereby the sleeve column 4 will drive the tooth opening 401 to move from the position of the tooth plate 201 to the position of the sleeve plate 202, so that the tooth plate 201 is disconnected from the tooth opening 401, and then the compressor body 1 can be controlled to rotate, thereby the compressor body 1 will drive the tooth plate 201 and the sleeve plate 202 to rotate, thereby realizing the rapid adjustment of the position of the compressor body 1, and at the same time, due to the rotation of the ball block 305 The rotation is inside the ball mouth 302, so when the compressor body 1 rotates, the compressor body 1 will drive the limiting circular plate 203 to rotate around the ball block 305. At this time, the ball block 305 will increase the rotation efficiency of the limiting circular plate 203, thereby improving the adjustment efficiency of the compressor body 1. After the position adjustment of the compressor body 1 is completed, the sleeve column 4 can be moved upward to drive the tooth mouth 401 to re-engage with the tooth plate 201, so that the sleeve column 4 limits the tooth plate 201, and thereby limits the position of the compressor body 1. Specific embodiment 2

[0032] See also Figure 2 , Figure 3 and Figure 5 On the basis of the first specific embodiment, the limiting circular plate 203 is limited at the inner position of the limiting opening 406, thereby ensuring the stable assembly of the sleeve column 4.

[0033] Specifically, a limiting opening 406 is provided at the middle position of the lower end surface of the sleeve 4, and the caliber of the limiting opening 406 is larger than the caliber of the tooth opening 401, the height of the tooth opening 401 is consistent with the height of the tooth plate 201, the sleeve plate 202 is slidably arranged in the inner position of the limiting opening 406, and the lower end surface of the sleeve plate 202 is fixed with a limiting circular plate 203 which is slidably connected to the inner side surface of the limiting opening 406, the limiting circular plate 203 is connected to the peripheral side of the ball block 305, the sleeve 4 is sleeved on the peripheral side of the round block 301 through the limiting opening 406, and the round block 301 is slidably connected to the inner side wall of the limiting opening 406.

[0034] The operation process of this embodiment is as follows: since the height of the limiting opening 406 is consistent with the height of the tooth plate 201, when the sleeve 4 is moved downward, the tooth openings 401 will all be driven out of the position of the tooth plate 201, so that the compressor body 1 can be easily controlled and adjusted. At the same time, the limiting circular plate 203 is in the limiting opening 406, and the diameter of the limiting opening 406 is larger than the diameter of the tooth opening 401. Therefore, the limiting opening 406 limits the limiting circular plate 203, so that the sleeve 4 will not fall out on the sleeve plate 202 and the tooth plate 201. Specific embodiment three

[0036] See also Figure 3 , Figure 4 and Figure 5 On the basis of the first specific embodiment, the use of the spring 408 can facilitate the resetting of the sleeve column 4, and the positioning rod 303 limits the positioning plate 402 to ensure that the sleeve column 4 does not rotate.

[0037] Specifically, two symmetrically arranged positioning plates 402 are fixed to the upper part of the peripheral side of the sleeve column 4, a circular opening 403 is opened in the middle position of the upper end surface of the positioning plate 402, and a positioning hole 404 connected to the inside of the circular opening 403 is opened in the middle position of the lower end surface of the positioning plate 402, and the left and right parts of the upper end surface of the mounting plate 3 are fixed with positioning rods 303 that slide through the inner position of the positioning hole 404, and the upper end surface of the positioning rods 303 is fixed with a stopper 304 that is rotatably set in the inner position of the circular opening 403, and two symmetrically arranged springs 408 are fixed at the position between the positioning plate 402 and the mounting plate 3, and the two springs 408 are respectively sleeved on the corresponding peripheral positions of the positioning rods 303, and two front-to-back symmetrically arranged arc plates 405 are fixed to the lower part of the peripheral side of the sleeve column 4, and the lower end surfaces of the arc plates 405 are fixed with pads 407.

[0038] The operation process of this embodiment is as follows: when the control sleeve column 4 moves downward, the sleeve column 4 will drive the positioning plate 402 to slide downward along the positioning rod 303, and then the positioning plate 402 will compress the spring 408. Therefore, when the user releases the sleeve column 4, the spring 408 will push the positioning plate 402 to move upward, so that the tooth mouth 401 can be controlled to move to engage with the tooth plate 201. At the same time, in order to facilitate the control of the sleeve column 4 to move downward, the user can step on the arc plate 405 with his foot to apply force to the arc plate 405, thereby driving the movement of the sleeve column 4, and the positioning rod 303 is in the positioning hole 404, and the stopper 304 is in the round mouth 403, so as to limit the positioning plate 402 and ensure that the sleeve column 4 will not rotate.
