Description

Technical Field

[0001] The utility model relates to the technical field of screw compressors, in particular to a screw compressor which is easy to assemble and disassemble. Background Art

[0002] Screw compressors are divided into two types: single screw and twin screw. Twin screw compressors have a pair of rotors with helical teeth that mesh with each other and rotate in opposite directions. Some screw compressors are equipped with a filter structure at the air inlet end to fix the gas center and prevent impurities from entering the gas inside the compressor, thereby preventing wear on the internal components;

[0003] After searching, a Chinese patent with the publication number of CN215566618U discloses a screw rod, which records that a pad subjected to the extrusion force of an elastic member will automatically push a tapered bearing, and the tapered bearing automatically fills the gap between it and the body or inside it by virtue of the tapered design, so as to prevent the gear shaft from losing the restriction of the tapered bearing and becoming loose, thereby causing oil leakage in the compressor;

[0004] In this solution, although the equipment solves the problem of oil leakage, the internal parts of the device will be damaged after long-term use. At this time, it is necessary to disassemble the outer shell and repair the internal parts of the equipment. Since the equipment is an integrated design, it is time-consuming and laborious to disassemble, which greatly reduces the work efficiency. In order to solve this technical problem, the utility model proposes a screw compressor that is easy to disassemble and assemble. Summary of the invention

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] See also Figure 1-5 , the utility model provides a technical solution:

[0025] Embodiment 1: A screw compressor that is easy to disassemble and assemble, comprising a compressor body 1 and a screw 4, wherein a drive motor is arranged inside the compressor body 1, and the screw 4 is fixedly connected to the output end of the drive motor, two sets of legs 2 are fixedly connected to the bottom of the compressor body 1, and a mounting plate 18 is fixedly connected to the front end of the compressor body 1, and a filter 3 is arranged outside the mounting plate 18, an upper cover plate 5 is arranged above the screw 4, and a lower base plate 10 is arranged below the screw 4, plug blocks 6 are fixedly connected to both sides of the upper cover plate 5, and a slide plate 11 is fixedly connected to both sides of the lower base plate 10, and a groove 12 is provided inside the slide plate 11, and a connecting rod 15 is arranged outside the slide plate 11, and an inner hole 9 is provided inside the plug block 6, the connecting rod 15 passes through the plug block 6 and the slide plate 11 and extends to the other side of the slide plate 11, and the other end of the connecting rod 15 A thread 17 is provided, and a nut 16 is provided at the other end of the connecting rod 15, and the nut 16 is threadedly connected to the connecting rod 15, the plug block 6 corresponds to the groove 12, and the plug block 6 is slidably connected in the groove 12, the connecting rod 15 passes through the plug block 6 and the slide plate 11 and extends to the other side of the slide plate 11, and the connecting rod 15 is slidably connected in the inner hole 9, a pair of connecting plates 7 are fixedly connected to the bottom of both ends of the upper cover plate 5, and a pair of inner grooves 13 are opened at both ends of the lower base plate 10, and the connecting plate 7 corresponds to the inner groove 13, and the connecting plate 7 is slidably connected in the inner groove 13, a pair of connecting columns 8 are fixedly connected to the bottom of both ends of the upper cover plate 5, and a pair of inner holes 14 are opened at the top of both ends of the lower base plate 10, and the connecting column 8 corresponds to the inner hole 14, and the connecting column 8 is slidably connected in the inner hole 14.

[0026] After the nut 16 is unscrewed from the connecting rod 15 and the connecting rod 15 is pulled out, the upper cover plate 5 and the lower base plate 10 can be easily disassembled, so that the screw rod 4 is exposed to the outside and the internal parts are easy to replace. After the replacement is completed, when reinstalling the upper cover plate 5 and the lower base plate 10, it is only necessary to align the connecting plate 7 and the connecting column 8 of the upper cover plate 5 with the inner groove 13 and the inner hole 2 14 on the lower base plate 10, and directly insert them to achieve the positioning effect. At the same time, the plug block 6 is inserted into the groove 12 of the slide plate 11 and slides into the slide plate 11. The connecting rod 15 passes through the slide plate 11 and is inserted into the other side of the slide plate 11 along the inner hole 19. Then, the nut 16 is rotated onto the connecting rod 15 and tightened until it fits with the outer wall of the slide plate 11, thereby quickly completing the installation of the upper cover plate 5 and the lower base plate 10. Such a design not only improves the installation speed, but also speeds up the efficiency of later maintenance, and at the same time plays a role in protecting the screw rod 4. The air is filtered by the filter 3 and the compressor body 1 is supported by the legs 2, and the cooperation between them improves the performance and reliability of the entire compressor.

[0027] When working, the screw compressor sucks in gas or gas mixture from the air inlet through two or more rotating screws, then gradually compresses it during the rotation of the screws, and releases the compressed gas through the exhaust port. When the compressor body 1 works for a long time, the internal parts will be worn and need to be replaced or repaired regularly. At this time, the nut 16 is unscrewed from the connecting rod 15, and the connecting rod 15 is pulled out. At this time, the upper cover plate 5 and the lower base plate 10 can be directly disassembled, and the screw 4 is exposed to the outside, and the internal parts are convenient for replacement. After the replacement is completed, the upper cover plate 5 and the lower base plate 10 need to be installed again. At this time, the connecting plates 7 and the connecting columns 8 on both sides of the upper cover plate 5 are aligned with the lower base plate 10. The inner groove 13 and the inner hole 2 14 on the upper surface are aligned with each other, and the positioning effect is achieved by directly inserting the plug block 6. When inserting, the plug block 6 is aligned with the groove 12 on the slide plate 11, and the plug block 6 will slide into the slide plate 11. At this time, the connecting rod 15 passes through the slide plate 11 and is inserted into the other side of the slide plate 11 along the inner hole 19. At this time, the nut 16 is rotated onto the connecting rod 15 and screwed to fit the outer wall of the slide plate 11. At this time, the upper cover plate 5 and the lower base plate 10 can be quickly installed, and at the same time, the screw 4 is protected. The air is filtered through the filter 3, and the compressor body 1 is supported by the support leg 2. Through their cooperation, the installation speed is greatly improved, and the efficiency of later maintenance is accelerated.
