Description

Technical Field

[0001] This utility model belongs to the field of compression equipment technology, and more specifically, it relates to an air suspension compression device with a frequency converter. Background Technology

[0002] Air suspension compressors convert kinetic energy into gas pressure energy through high-speed impeller rotation to achieve air compression. To accurately match the gas load and ensure economical operation, frequency converters are usually configured to detect the gas flow demand and adjust the motor speed so that the equipment output is precisely matched with the load. At the same time, in the process of air compression by centrifugal compressors, filters are used to purify the intake air to protect the core components of the compressor.

[0003] Based on the above, in the actual application of air suspension compressor equipment, in order to ensure the stable operation of the centrifugal compressor, the filter needs to be replaced regularly. However, in the operation and maintenance of the compressor equipment, it is very easy for maintenance personnel to fail to conduct timely inspections, fail to pay attention to clogging monitoring data such as differential pressure and flow, miss the filter replacement point, or fail to predict the filter clogging speed, fail to consider environmental dust concentration, humidity and other factors, and fail to replace the filter in time. As a result, the adsorbed impurities will condense on the surface of the filter material, causing the filter to lose its purification function and continuously release impurities, causing secondary pollution. At the same time, insufficient air intake will force the compressor to run at high load for a long time, resulting in a sharp increase in energy consumption and affecting operating efficiency. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an air suspension compressor with a frequency converter. This addresses the issue that, in the practical application of air suspension compressors, to ensure stable operation of the centrifugal compressor, regular filter replacement is necessary. However, during the operation and maintenance of the compressor, it is easy for maintenance personnel to fail to conduct timely inspections, neglect monitoring data such as differential pressure and flow rate, miss filter replacement points, or underestimate the rate of filter clogging, failing to consider environmental dust concentration, humidity, and other factors, thus failing to replace the filter in a timely manner. This results in adsorbed impurities condensing on the filter media surface, causing the filter to lose its purification function and continuously release impurities, causing secondary pollution. Furthermore, insufficient air intake forces the compressor to operate at high load for extended periods, leading to a surge in energy consumption and affecting operational efficiency.

[0005] The purpose and effect of this utility model of an air suspension compression device with a frequency converter are achieved by the following specific technical means:

[0006] An air suspension compressor with a frequency converter includes a protective housing, a frequency converter, a turbine blower, an intake pipe, an exhaust pipe, and a monitoring auxiliary mechanism. The frequency converter is located on the left side inside the protective housing; the turbine blower is located on the right side inside the protective housing; the frequency converter and the turbine blower are electrically connected via a control module; the control module is located at the left end inside the protective housing; an operation panel is provided on the left end face of the protective housing; the operation panel is electrically connected to the control module; the intake pipe is fixedly connected to the intake port of the turbine blower; the exhaust pipe is fixedly connected to the exhaust port of the turbine blower; the monitoring auxiliary mechanism is located at the inner ends of the intake pipe and the exhaust pipe; the monitoring auxiliary mechanism includes two drive shafts, each rotatably positioned at the center of the inner side of the intake pipe and the exhaust pipe.

[0007] Furthermore, a filter is threadedly connected to the inner end of the air intake pipe; multiple disassembly and assembly auxiliary slots are arranged circumferentially on the inner side of the filter frame; the disassembly and assembly auxiliary slots are U-shaped slot structures.

[0008] Furthermore, the monitoring auxiliary mechanism also includes: a positioning bracket and a positioning auxiliary block. There are two positioning brackets, which are fixedly connected to the air intake pipe and the exhaust pipe, respectively. The positioning auxiliary block is fixedly connected to the transmission shaft coaxially and is located on the inner end face of the transmission shaft. The two transmission shafts are rotatably connected to the two positioning brackets, respectively.

[0009] Furthermore, the monitoring auxiliary mechanism also includes: a drive impeller and a sliding guide block. There are two drive impellers, which are coaxially and fixedly connected to two transmission shafts respectively. The drive impellers are located at the outer end of the transmission shafts. The middle section of the transmission shaft is a polygonal shaft structure. There are two sets of sliding guide blocks, which are symmetrical front and back and slidably connected to the polygonal shaft section of the transmission shaft. Rubber balls are fixedly connected to the outer sides of the two sets of sliding guide blocks by traction ropes.

[0010] Furthermore, the monitoring auxiliary mechanism also includes: positioning support rings, of which there are two sets, and the two sets of positioning support rings are rotatably connected to two transmission shafts respectively; the opposing surfaces of the positioning support rings and the sliding guide block are elastically connected to the abutment rings through elastic reset members; the abutment rings on the same side are rotatably connected to the sliding guide block.

[0011] Furthermore, the outer ends of the two front-end contact rings are fixedly connected to connecting posts; the outer ends of the connecting posts are vertically fixedly connected to pressing posts.

[0012] Furthermore, the monitoring auxiliary mechanism also includes: an audible and visual alarm and a stop switch. The audible and visual alarm is installed on the top end face of the protective housing and is electrically connected to the control module. There are two stop switches, which are fixedly connected to the inner walls of the air inlet pipe and the exhaust pipe respectively through positioning blocks. The stop switches are electrically connected to the audible and visual alarm. The stop switches are aligned with the pressing column.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In use, this utility model features a U-shaped disassembly and assembly auxiliary groove circumferentially set in the filter frame, combined with the threaded connection structure between the air inlet pipe and the filter. This allows for quick and easy disassembly and assembly of the filter without the need for special tools, significantly shortening the filter replacement operation time. It solves the problems of cumbersome filter disassembly and assembly and low maintenance efficiency in traditional compression equipment. At the same time, the threaded connection method ensures the sealing of the filter after installation, preventing air leakage from affecting compression efficiency, and further improving the practicality and reliability of operation and maintenance.

[0015] In use, this utility model relies on the airflow-driven monitoring auxiliary mechanism inside the air intake pipe. The airflow drives the drive impeller to rotate the transmission shaft. The centrifugal force and the elastic reset component work together to control the contact state between the pressing column and the stop switch. When the filter is clogged and the air intake volume is reduced, the speed of the transmission shaft decreases, the elastic reset component drives the pressing column to disengage from the stop switch, and triggers the audible and visual alarm to sound an alarm immediately. This realizes dynamic monitoring based on the actual air intake conditions, avoids the delay in replacement caused by untimely manual inspection and insufficient prediction, and solves the subjectivity and lag problems of traditional manual monitoring.

[0016] When in use, this utility model provides timely warnings via an audible and visual alarm, allowing staff to quickly replace clogged filters. This effectively prevents secondary pollution caused by the release of impurities that condense on the filter material surface, and avoids impurities entering the turbine blower and wearing down core components such as the impeller, thus extending the compressor's service life. At the same time, timely filter replacement ensures a stable air intake, preventing the compressor from being forced to operate at high loads for extended periods due to insufficient air intake. This significantly reduces energy consumption, improves the economy and stability of equipment operation, and solves the problem of increased energy consumption and decreased operating efficiency caused by filter clogging in traditional equipment.

The two transmission shafts 701 are rotatably connected to the two positioning brackets 702 respectively.

[0032] The specific usage and function of this embodiment are as follows:

[0033] When in use, this utility model utilizes the U-shaped disassembly and assembly auxiliary groove 502 circumferentially of the filter 501, along with its threaded connection structure with the air intake pipe 5, to quickly disassemble and assemble the filter 501 without special tools, significantly improving the convenience of replacement operations. The positioning bracket 702 and the positioning auxiliary block 703 work together to achieve positioning support for the transmission shaft 701.

[0034] Example 2:

[0035] As attached Figure 3 To be continued Figure 7 As shown:

[0036] Based on Example 1:

[0037] The monitoring auxiliary mechanism also includes: a drive impeller 704 and a sliding guide block 705. There are two drive impellers 704, which are coaxially and fixedly connected to two transmission shafts 701 respectively. The drive impellers 704 are located at the outer end of the transmission shafts 701. The middle section of the transmission shaft 701 is a polygonal shaft structure. There are two sets of sliding guide blocks 705. The two sets of sliding guide blocks 705 are symmetrical front and back and are slidably connected to the polygonal shaft section of the transmission shaft 701. Rubber balls 707 are fixedly connected to the outer side of the two sets of sliding guide blocks 705 by traction ropes 706.

[0038] The monitoring auxiliary mechanism also includes: a positioning support ring 708, of which there are two sets, and the two sets of positioning support rings 708 are rotatably connected to two transmission shafts 701 respectively; the opposite surfaces of the positioning support ring 708 and the sliding guide block 705 are elastically connected to the abutment ring 709 through the elastic reset member 710; the abutment ring 709 on the same side is rotatably connected to the sliding guide block 705.

[0039] Among them, the outer ends of the two front abutment rings 709 are fixedly connected to the connecting post 711; the outer ends of the connecting post 711 are vertically fixedly connected to the pressing post 712.

[0040] The monitoring auxiliary mechanism also includes: an audible and visual alarm 7 and a stop switch 713. The audible and visual alarm 7 is installed on the top end face of the protective housing 1 and is electrically connected to the control module 4. There are two stop switches 713. The two stop switches 713 are fixedly connected to the inner walls of the air inlet pipe 5 and the exhaust pipe 6 respectively through positioning blocks 714. The stop switches 713 are electrically connected to the audible and visual alarm 7. The stop switches 713 are aligned with the pressing column 712.

[0041] The specific usage and function of this embodiment are as follows:

[0042] In use, the stop switch 713 is a normally closed switch. When pressed, it disconnects the alarm circuit; when released, it closes and triggers the audible and visual alarm 7. During normal air intake, the airflow drives the impeller 704 and the transmission shaft 701 to rotate at high speed. Under centrifugal force, the two sets of sliding guide blocks 705 overcome the elastic force of the elastic reset member 710 and slide outward. Through the contact ring 709 and the connecting column 711, they sequentially drive the pressing column 712 to press the stop switch 713. At this time, the alarm circuit is in the open state, and the audible and visual alarm 7 does not work. When the filter 501 is clogged, causing a reduction in air intake, the speed of the transmission shaft 701 decreases. When the centrifugal force weakens and drops below the critical value of the reset force of the elastic reset member 710, the sliding guide block 705 resets inward under the action of the elastic reset member 710, driving the pressing column 712 to disengage from the stop switch 713. The stop switch 713 then resets and closes, thereby triggering the audible and visual alarm 7 to start the alarm. When the ambient dust concentration is high and the humidity is high, the filter 501 clogs faster, the air intake decreases rapidly, the speed of the transmission shaft 701 decreases synchronously, and the centrifugal force weakens faster than under normal operating conditions. At this time, the elastic reset member 710 can quickly drive the pressing column 712 to disengage from the stop switch 713, realizing dynamic adaptation of the clog warning.
