Description

Technical Field

[0001] This utility model relates to the field of compressor technology, specifically to a spiral guide for compressors. Background Technology

[0002] A compressor is a mechanical device used to increase gas pressure, mainly compressing low-pressure gas into high-pressure gas. It is commonly used for gas transmission, storage, and processing, and is widely applied in industries such as refrigeration and air conditioning systems, industrial gas production and transportation, oil and gas development, automation and manufacturing, and food and beverage processing. Among them, the worm gear guide (also known as the volute or worm wheel) for compressors is an important component, mainly used to guide gas into the impeller or rotor of the compressor.

[0003] However, existing worm gear guides still have some problems in practical use: the worm gear guide will generate heat during operation, and if the heat dissipation is not good, the temperature may be too high and affect the performance of the compressor. Secondly, if there are impurities or particulate matter in the system, the worm gear may be blocked, affecting gas flow and compression effect. To address these issues, we propose a worm gear guide for compressors. Utility Model Content

[0025] The heat sink 3 includes heat sink fins 31, which are arranged in a ring array. Multiple heat sink fins 31 are fixedly connected to the outer wall of the volute 1. Arc-shaped liquid guide tubes 32 are fixedly fastened to the top and bottom of each heat sink fin 31. One end of each of the two arc-shaped liquid guide tubes 32 is fixedly connected to a connecting tube 33. A first connector 34 is fixedly installed at the top end of the arc-shaped liquid guide tube 32 away from the connecting tube 33. A second connector 35 is fixedly installed at the bottom end of the arc-shaped liquid guide tube 32 away from the connecting tube 33. In use, the first connector 34 and the second connector 35 are connected respectively... The coolant is connected to the input and output of the external coolant circulation system. When the compressor is used for a long time, the volute guide will generate heat. At this time, the external coolant circulation system can be controlled. The coolant is introduced into the other volute guide tube 32 through the second connector 35, one of the arc-shaped guide tubes 32 and the connecting pipe 33, and then circulated into the coolant circulation system through the first connector 34, realizing the circulation of coolant in the two arc-shaped guide tubes 32, thereby dissipating heat from the heat dissipation fins 31, and then effectively dissipating heat from the volute 1 through the heat dissipation fins 31, thereby preventing the volute guide temperature from being too high and affecting the performance of the compressor.

[0026] The filter element 4 includes a limiting ring frame 41, which is fixedly snapped into the inner wall of the guide pipe 2. A filter ring frame 42 is provided on the side of the limiting ring frame 41 away from the volute 1. An installation retaining ring 43 is integrally formed in the middle of the filter ring frame 42, which is movably snapped into the limiting ring frame 41. A filter element 44 is detachably installed in the middle of the installation retaining ring 43. A fastening screw ring 45 is provided on the side of the filter ring frame 42 away from the limiting ring frame 41. The fastening screw ring 45 is threaded onto the inner wall of the guide pipe 2. By setting the filter element 44, when the compressor is in use, the airflow introduced into the guide pipe 2 can be filtered for impurities or particulate matter through the filter element 44, thereby effectively preventing impurities or particulate matter from clogging the volute and affecting gas flow and compression effect. Furthermore, the filter ring frame 42 and filter element 44 can be disassembled by rotating and disassembling the fastening screw ring 45 with a tool, which facilitates the inspection and replacement of the filter element 44.

[0027] A positioning protrusion 421 is fixedly installed on the side of the filter ring frame 42 near the limiting ring frame 41. The limiting ring frame 41 has a positioning slot 422 corresponding to the positioning protrusion 421. The positioning protrusion 421 is movably engaged in the corresponding positioning slot 422. By setting the positioning protrusion 421, the positioning protrusion 421 is movably engaged in the corresponding positioning slot 422, so as to position and install the filter ring frame 42, thereby facilitating the disassembly of the filter ring frame 42.

[0028] An installation base 11 is fixedly installed on the bottom outer side of the volute 1, and the installation base 11 has evenly distributed installation bottom holes; an installation top seat 12 is fixedly installed on the top outer side of the volute 1, and the installation top seat 12 has evenly distributed installation top holes. By setting the installation base 11 and the installation top seat 12, it is convenient to install and fix the entire volute guide.

[0029] Working principle: During use, the entire spiral guide is installed and fixed by mounting base 11 and mounting top 12, and the first connector 34 and the second connector 35 are connected to the input and output ends of the external coolant circulation system, respectively.

[0030] When the compressor is in use, the airflow introduced into the guide pipe 2 can be filtered by the filter element 44 to remove impurities or particulate matter, thereby effectively preventing impurities or particulate matter from clogging the volute and affecting gas flow and compression effect. Furthermore, by using tools to rotate and disassemble the fastening screw ring 45, the filter ring frame 42 and the filter element 44 can be disassembled, which facilitates the inspection and replacement of the filter element 44.

[0031] Furthermore, when the compressor is used for a long time, the volute guide will generate heat. At this time, the external coolant circulation system can be controlled. The coolant is introduced into the other volute guide tube 32 through the second connector 35, one of the arc-shaped guide tubes 32 and the connecting pipe 33, and then circulated into the coolant circulation system through the first connector 34, realizing the circulation of coolant in the two arc-shaped guide tubes 32, thereby dissipating heat from the heat dissipation fins 31, and then effectively dissipating heat from the volute 1 through the heat dissipation fins 31, thereby preventing the volute guide temperature from being too high and affecting the performance of the compressor.
