Description

Technical Field

[0001] This invention relates to the field of air compressors, and more specifically, to a twin-screw air compressor. Background Technology

[0002] Twin-screw air compressors, due to their simple structure, few vulnerable parts, ability to operate under large pressure differences or pressure ratios with low exhaust temperatures, insensitivity to refrigerants containing large amounts of lubricating oil, and good gas delivery capacity regulation, have quickly occupied the application range of large-capacity reciprocating compressors and are continuously extending to the medium-capacity range, and are widely used in refrigeration equipment such as refrigeration, cold storage, air conditioning, and chemical processes.

[0003] The dual-threaded rod air compressor in the related technology is equipped with a pre-filter. When the pre-filter needs to be cleaned, at least four bolts need to be removed to disassemble the pre-filter. Installation also requires installing multiple bolts, which reduces the efficiency of disassembling and assembling the pre-filter. Summary of the Invention

[0004] To overcome the above shortcomings, this invention provides a twin-screw air compressor, which aims to improve the efficiency of cleaning and installing a pre-filter, which requires removing at least four bolts to disassemble the pre-filter and installing multiple bolts.

[0005] This invention is implemented as follows:

[0006] This invention provides a twin-screw air compressor, including a base component and a disassembly / assembly component.

[0007] The basic components include a twin-screw air compressor body and a leveling part. The leveling part is disposed on the lower surface of the twin-screw air compressor body, and a first groove and a second groove are formed on the housing of the twin-screw air compressor body.

[0008] The assembly / disassembly components include a slide rail, a slider, a locking block, a first vertical plate, a second vertical plate, a pre-filter, and a first locking member. The slide rail is fixed on the second groove, the slider is slidably disposed on the slide rail, and the side surface of the slider is fixed on the side surface of the locking block. The first and second vertical plates are both fixed on the pre-filter. The locking block is inserted into the first groove, the second vertical plate is inserted into the body of the twin-screw air compressor, the first vertical plate is inserted into the locking block, and the first locking member is threaded through the locking block, with its end also threaded into the first groove.

[0009] In one embodiment of the present invention, the leveling part includes a support column and a threaded column, the support column being fixed to the lower surface of the twin-screw air compressor body, and the threaded column being threaded inside the support column.

[0010] In one embodiment of the present invention, a through hole is provided on the body of the twin-screw air compressor, and the pre-filter is disposed in the through hole.

[0011] In one embodiment of the present invention, a third groove is provided on the body of the twin-screw air compressor, and the second vertical plate is engaged in the third groove.

[0012] In one embodiment of the present invention, at least two sliders are provided on the slide rail, and the sliders are equidistantly arranged on the slide rail.

[0013] In one embodiment of the invention, the disassembly assembly further includes a spring fixed between the upper surface of one of the sliders and the inner wall of the second groove.

[0014] In one embodiment of the present invention, the twin-screw air compressor body is provided with a threaded groove, and the end of the first locking member is threaded in the threaded groove.

[0015] In one embodiment of the present invention, the disassembly and assembly assembly further includes a guide sleeve, which is fixed inside the card block, and the first vertical plate slides through the guide sleeve.

[0016] In one embodiment of the present invention, the disassembly assembly further includes a second locking member, the second locking member being threaded through the locking block.

[0017] In one embodiment of the present invention, the disassembly and assembly assembly further includes a handheld part, which is fixed to the outer wall of the card block.

[0018] The beneficial effects of this invention are as follows: The twin-screw air compressor obtained by the above design, when the pre-filter needs to be cleaned after use, involves rotating the first locking member to disengage its end from the threaded groove, pushing the locking block upwards, and moving it upwards towards the first groove to provide sufficient space for the upward movement of the first and second vertical plates. Then, the second locking member is rotated, and its end presses against the inner wall of the first groove, fixing the locking block in place. Afterwards, the pre-filter is moved upwards, causing the second vertical plate to disengage from the third groove. The pre-filter can be removed and cleaned. Then, the second vertical plate on the pre-filter is inserted into the third groove, and the second locking member is rotated in the opposite direction so that the end of the second locking member leaves the outer wall of the first groove. The locking block is then fitted onto the first vertical plate under the reaction force of the spring. Finally, the first locking member is rotated so that the end of the first locking member enters the threaded groove, thus installing the pre-filter onto the twin-screw air compressor body. This twin-screw air compressor only requires the operation of the first locking member to disassemble and assemble the pre-filter, improving the efficiency of disassembly and assembly of the pre-filter.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example

[0028] Please see Figure 1-5 The present invention provides a technical solution: a twin-screw air compressor, including a base component 100 and a disassembly / assembly component 200. The disassembly / assembly component 200 is disposed on the base component 100. The twin-screw air compressor only requires operation of a first locking member 291 to disassemble and assemble the pre-filter 290, thereby improving the efficiency of disassembly and assembly of the pre-filter 290.

[0029] Please see Figures 1-3 The basic component 100 includes a twin-screw air compressor body 110 and a leveling part 120. The leveling part 120 is disposed on the lower surface of the twin-screw air compressor body 110. The leveling part 120 includes a support column 121 and a threaded column 122. The support column 121 is fixed on the lower surface of the twin-screw air compressor body 110. The threaded column 122 is threaded in the support column 121. The threaded column 122 enables the air compressor to adapt to uneven ground. The housing of the twin-screw air compressor body 110 is provided with a first groove 140 and a second groove 150.

[0030] Please see Figure 2 , Figure 4 and Figure 5The disassembly / assembly assembly 200 includes a slide rail 210, a slider 220, a locking block 240, a first vertical plate 270, a second vertical plate 280, a pre-filter 290, and a first locking member 291. The slide rail 210 is fixed on the second groove 150. The slider 220 is slidably disposed on the slide rail 210, and the side surface of the slider 220 is fixed on the side surface of the locking block 240. At least two sliders 220 are provided on the slide rail 210, and the sliders 220 are equidistantly disposed on the slide rail 210. The multiple sliders 220 enable the locking block 240 to move more smoothly within the first groove 140. The disassembly / assembly assembly 200 also includes a spring 230, which is fixed between the upper surface of one of the sliders 220 and the inner wall of the second groove 150. The spring 230 causes the locking block 240 to move more smoothly within the first groove 140. Under the reaction force of 230, it is more quickly fitted onto the first vertical plate 270. The first vertical plate 270 and the second vertical plate 280 are both fixed on the pre-filter 290. The locking block 240 is inserted into the first groove 140. The second vertical plate 280 is inserted into the twin-screw air compressor body 110. The twin-screw air compressor body 110 has a third groove 160. The second vertical plate 280 is locked into the third groove 160. The third groove 160 facilitates the insertion of the second vertical plate 280 into the twin-screw air compressor body 110. The disassembly and assembly assembly 200 also includes a guide sleeve 260. The guide sleeve 260 is fixed in the locking block 240. The first vertical plate 270 slides through the guide sleeve 260. The guide sleeve 260 makes the first vertical plate 270 enter the locking block 240 more smoothly.

[0031] The first vertical plate 270 is inserted into the locking block 240. The first locking member 291 is threaded through the locking block 240, and the end of the first locking member 291 is also threaded into the first groove 140. A threaded groove 250 is provided on the twin-screw air compressor body 110, and the end of the first locking member 291 is threaded into the threaded groove 250. The threaded groove 250 facilitates fixing the locking block 240 into the first groove 140. A through hole 130 is provided on the twin-screw air compressor body 110, and a pre-filter 290 is disposed in the through hole 130. The through hole 130 facilitates the installation of the pre-filter 290 onto the twin-screw air compressor body 110. (Disassembly / reassembly assembly 20) The assembly also includes a second locking member 292, which is threaded through the locking block 240. After the locking block 240 is moved, when it is necessary to fix the locking block 240, the locking block 240 is held and the second locking member 292 is rotated. The end of the second locking member 292 presses against the inner wall of the first groove 140, thereby fixing the locking block 240. In this embodiment, both the first locking member 291 and the second locking member 292 are bolts. The disassembly and assembly assembly 200 also includes a handle 293, which is fixed to the outer wall of the locking block 240. The handle 293 facilitates pushing and pulling the locking block 240. In this embodiment, the handle 293 is a handle.

[0032] Specifically, the working principle of this twin-screw air compressor is as follows: After use, when cleaning the pre-filter 290, rotate the first locking member 291 so that its end leaves the threaded groove 250, pushing the locking block 240 upwards. This moves the locking block 240 upwards towards the first groove 140, providing sufficient space for the upward movement of the first vertical plate 270 and the second vertical plate 280. Then, rotate the second locking member 292, whose end presses against the inner wall of the first groove 140, fixing the locking block 240 in place. Afterwards, move the pre-filter 290 upwards, causing the second vertical plate 280 to leave the third groove 160, thus cleaning the pre-filter 290. After removing the pre-filter 290 and cleaning it, insert the second vertical plate 280 on the pre-filter 290 into the third groove 160, then rotate the second locking member 292 in the opposite direction so that the end of the second locking member 292 leaves the outer wall of the first groove 140. The locking block 240 is fitted onto the first vertical plate 270 under the reaction force of the spring 230. Finally, rotate the first locking member 291 so that the end of the first locking member 291 enters the threaded groove 250, thus installing the pre-filter 290 onto the twin-screw air compressor body 110. This twin-screw air compressor only requires the operation of the first locking member 291 to disassemble and assemble the pre-filter 290, improving the efficiency of disassembling and assembling the pre-filter 290.

[0033] It should be noted that the specific model and specifications of the twin-screw air compressor body 110 and the pre-filter 290 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0034] The power supply and principle of the twin-screw air compressor body 110 and the pre-filter 290 are clear to those skilled in the art and will not be described in detail here.

[0035] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
