Description

Technical Field

[0001] The utility model relates to a screw air compressor seal, in particular to a dustproof, moisture-proof and highly sealed screw air compressor, belonging to the technical field of screw air compressors. Background Art

[0002] Domestic variable frequency screw air compressors are improved based on the original quality and according to different domestic environments, making the products more superior for domestic use. The air compressor usage scenarios generally have the following characteristics: the configuration capacity is larger than the actual gas volume, the gas consumption is unstable, the air pressure requirement is stable, and the noise must be as low as possible. The variable frequency air compressor automatically changes the host speed according to the amount of gas used to respond to changes in system pressure and maintain a stable system pressure. When the system consumes less air, the amount of compressed air provided by the compressor will be greater than the system consumption. The variable frequency compressor will reduce the speed and output compressed air at the same time to maintain a stable system pressure value. If the system consumes more air, the amount of compressed air provided by the compressor will be less than the system consumption. The variable frequency compressor speed will increase relatively and output compressed air at the same time to maintain a stable system pressure value.

[0003] When the variable frequency screw air compressor equipment is not working, since the heat dissipation ports on both sides of the variable frequency screw air compressor equipment do not have the function of protection and sealing, dust and debris fall into the variable frequency screw air compressor equipment through the heat dissipation ports, and also make the inside of the variable frequency screw air compressor equipment moist, affecting subsequent use. The existing air compressor sealing method mostly uses sealing gaskets to seal the heat dissipation ports, but the sealing gaskets are prone to displacement, which reduces the sealing effect, and then leads to reduced dust and moisture proof effects.

[0004] Therefore, a dustproof, moisture-proof and highly sealed screw air compressor is proposed. Utility Model Content

DETAILED DESCRIPTION

[0024] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0025] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0026] like Figure 1 , Figure 2 and Figure 6 As shown, the embodiment of the utility model provides a dustproof, moisture-proof and highly sealed screw air compressor, including a base plate 1, a protective box 2 is fixedly connected to the top of the base plate 1, an adjustment box 4 is fixedly connected to the back side of the top of the base plate 1, a servo motor 18 is fixedly connected to the top of the adjustment box 4, a threaded rod 19 is fixedly connected to the output end of the servo motor 18, a threaded sleeve 20 is threadedly connected to the surface of the threaded rod 19, a connecting rod 6 is fixedly connected to the front side of the connecting rod 6, a card plate 7 is fixedly connected to the front side of the card plate 7, A sealing box 3 is fixedly connected to the inner side, a sealing plate 8 is fixedly connected to the bottom of the sealing box 3, an inspection door 12 is provided on the top of the protective box 2, and the sealing plate 8 is clamped in the inner cavity of the inspection door 12. Slide grooves 21 are provided on the left and right sides of the inner wall of the adjusting box 4, and sliders 22 are fixedly connected to the left and right sides of the screw sleeve 20. The outer side of the slider 22 is slidably connected to the inner cavity of the slide groove 21. A through groove 5 is provided on the front surface of the adjusting box 4, and the front side of the connecting rod 6 passes through the inner cavity of the through groove 5 and extends to the front side of the adjusting box 4.

[0027] In one embodiment, by cooperating with the sealing box 3 and the protective box 2, the screw air compressor body 9 can be covered and sealed in the inner cavity of the protective box 2 and the sealing box 3, thereby improving the dust and moisture proof effect of the screw air compressor body 9. By cooperating with the screw air compressor body 9 and the inspection door 12, the sealing effect of the screw air compressor body 9 can be further improved. The threaded rod 19 is driven to rotate by the output end of the servo motor 18. The threaded rod 19 drives the screw sleeve 20 to move up and down by the action of the thread. The screw sleeve 20 drives the sealing box 3 to move up and down through the connecting rod 6 and the clamping plate 7, so that the sealing box 3 is pushed upward when the screw air compressor body 9 is used, so as to avoid affecting the use performance of the screw air compressor body 9. In the process of the screw sleeve 20 moving up and down, the slider 22 moves up and down along the inner cavity of the slide groove 21, which can effectively improve the stability of the screw sleeve 20 in the process of moving up and down, and avoid the screw sleeve 20 rotating with the rotation of the threaded rod 19.

[0028] In this embodiment, Figure 3 As shown, a screw air compressor body 9 is placed in the inner cavity of the protective box 2, and dustproof nets 10 are embedded on the left and right sides of the screw air compressor body 9. The front surface of the screw air compressor body 9 is movably connected with a slot 11 through a hinge.

[0029] In one embodiment, the heat generated in the inner cavity of the screw air compressor body 9 can be dissipated through the dustproof net 10, and the inner cavity of the screw air compressor body 9 can be inspected and repaired through the slot 11.

[0030] In this embodiment, Figure 4 and Figure 5As shown, a holder 13 is fixedly connected to the top of the inner cavity of the sealing box 3, a drying box 14 is clamped in the inner cavity of the holder 13, and the inner cavity of the drying box 14 is filled with a desiccant, guide rods 15 are provided on both sides of the inner cavity of the holder 13, and a return spring 16 for driving the guide rod 15 to move horizontally is sleeved on the surface of the guide rod 15, and a clamping block 17 is fixedly connected to the inner side of the guide rod 15, and the inner side of the clamping block 17 is clamped to the outer side of the drying box 14.

[0031] In one embodiment, by arranging the drying box 14 in the inner cavity of the sealing box 3, the drying effect in the inner cavity of the sealing box 3 can be improved, thereby improving the moisture-proof performance of the screw air compressor body 9. By arranging the holder 13, the drying box 14 can be easily installed. By arranging the guide rod 15, the return spring 16 and the block 17, the drying box 14 can be conveniently limited by the elastic force to prevent the drying box 14 from falling, and the subsequent disassembly and replacement of the drying box 14 is convenient.

[0032] When the utility model is working:

[0033] First, the guide rod 15 is pulled outward to drive the reset spring 16 to deform and squeeze outward, and then the drying box 14 is clamped in the inner cavity of the clamping seat 13, and the guide rod 15 is released. At this time, the reset spring 16 recovers its deformation and extends inward due to the loss of force, and drives the guide rod 15 and the clamping block 17 to move inward, thereby fixing the drying box 14. The drying box 14 can improve the drying effect in the surrounding environment;

[0034] Then the output end of the servo motor 18 drives the threaded rod 19 to rotate, and the threaded rod 19 drives the screw sleeve 20 to move downward through the action of the thread, and the screw sleeve 20 drives the connecting rod 6 to move downward, and the connecting rod 6 drives the sealing box 3 to move downward through the through groove 5, so that the sealing plate 8 is clamped in the inner cavity of the inspection door 12, and a sealed cavity is formed through the cooperation of the sealing box 3 and the protection box 2, and the whole of the screw air compressor body 9 is sealed. At the same time, the cooperation of the sealing plate 8 and the inspection door 12 improves the sealing effect between the protection box 2 and the sealing box 3, thereby improving the dust and moisture proof effect of the screw air compressor body 9;

[0035] When the screw air compressor body 9 needs to be used, the output end of the servo motor 18 drives the threaded rod 19 to rotate in the opposite direction, and the threaded rod 19 drives the sealing box 3 to move upward through the threaded sleeve 20, so that the sealing box 3 is located above the screw air compressor body 9 to avoid affecting the performance of the screw air compressor body 9.

[0036] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
