Description

Technical Field

[0001] The utility model relates to the technical field of air compressors, in particular to an air intake device for a high-pressure air compressor. Background Art

[0002] The air intake filter device of a high-pressure air compressor is a key component to ensure efficient and stable operation of the compressor. Its main function is to remove impurities, dust, moisture, etc. in the air before the air is compressed to protect the internal components of the compressor, extend the life of the equipment, and improve the overall efficiency of the system. The device consists of a filter element, a housing, and a seal. The filter element is the core part and is responsible for capturing impurities, while the housing protects the filter element and ensures its safe connection with the air compressor system. The seal ensures the air tightness of the system and prevents the entry of unfiltered air. For example, an air intake device of an air compressor disclosed in the authorization announcement number CN210422954U includes an air intake pipe and a filter device arranged in the air intake pipe. The air intake pipe has an air intake end and an exhaust end. The outer side of the air intake end is installed There is a guardrail, a flange is connected to the exhaust end, and a sealing ring is connected to the flange; the filtering device includes a primary filtering device arranged on one side of the air inlet end and a high-level filtering device arranged on one side of the exhaust end, which is installed at the air inlet of the air compressor, and can filter and cool the inhaled air, thereby ensuring the quality of the inhaled air and reducing the damage to the air compressor. However, the filter element in this technical solution is built into the air intake pipe. When the air intake device is used for a period of time and is replaced, the entire air intake device needs to be disassembled and replaced. The process of replacing the entire air intake device is relatively cumbersome and requires professional technicians to operate, which increases the difficulty and cost of maintenance. In addition, the complicated maintenance process makes the conventional filter element replacement time-consuming and labor-intensive, which directly affects the maintainability of the system.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-4 The utility model provides an embodiment: an air intake device for a high-pressure air compressor, comprising a support plate 1 and a split air intake structure and a flat head pipe 2 respectively installed on the outer walls of both sides of the support plate 1, an end of the flat head pipe 2 away from the support plate 1 is fixed with an internal threaded sleeve 3, the internal thread of the internal threaded sleeve 3 is equipped with a tube shell 4, a cross ventilation disk 7 is fixed to one end inside the internal threaded sleeve 3, and a plurality of equally spaced guide holes 701 are arranged on the surface of the cross ventilation disk 7;

[0018] A columnar filter element 6 is installed on the outer wall of the cross ventilation disk 7 close to the tube shell 4 through an arc-shaped plug-in structure 8. A sealing cover 5 for pressing against the end of the columnar filter element 6 is threadedly installed at one end of the tube shell 4 away from the flat head tube 2. External air enters the flat head tube 2, the internal threaded ring sleeve 3 and the columnar filter element 6 through the split air intake structure. Inside the columnar filter element 6, impurities and dust in the air will be captured by the filter element, while relatively clean air will enter the tube shell 4 through the columnar filter element 6, and enter the high-pressure air compressor through the sealing cover 5 and the one-way air intake valve;

[0019] A ventilation hole 502 is provided on the outer wall of one side of the sealing cover 5, and an annular flange 501 is installed on the inner wall of one side of the sealing cover 5. The top of the annular flange 501 abuts against the outer wall of one side of the rear cover 602, and the annular flange 501 is used to tighten the columnar filter element 6;

[0020] The split air intake structure includes two symmetrical split manifolds 101 mounted on the outer wall of one side of the support plate 1, one end of the split manifold 101 extends to the inside of the flat head tube 2, and the bottom ends of the two split manifolds 101 are jointly mounted with a main air intake head 102;

[0021] During the intake process, the external air first enters the main intake head 102, and then enters the flat head tube 2, the internal threaded ring sleeve 3 and the tube shell 4 through the diversion manifold 101. By evenly distributing the intake air to different channels, it can ensure that the air flow velocity of each channel is relatively uniform, preventing the problem of local pressure imbalance in the system caused by excessive concentration;

[0022] The columnar filter element 6 is composed of a front cover 601, a rear cover 602 and a filter screen 603, and the filter screen 603 is fixed between the front cover 601 and the rear cover 602;

[0023] The arc-shaped plug-in structure 8 includes an arc-shaped plug-in block 802 fixed on the outer wall of one side of the front cover 601, and an arc-shaped hollow seat 801 fixed on the outer wall of one side of the cross ventilation disk 7. The arc-shaped hollow seat 801 and the arc-shaped plug-in block 802 are plugged into each other. When removing the columnar filter element 6, the staff screws the sealing cover 5 off the end of the tube shell 4, and the arc-shaped plug-in block 802 on the outer wall of the front cover 601 is no longer connected with the arc-shaped hollow seat 801, until the front cover 601, the filter screen 603, and the rear cover 602 are completely pulled out of the tube shell 4;

[0024] The stability of the columnar filter element 6 after assembly is ensured by the arc-shaped plug block 802 and the arc-shaped hollow seat 801. This stable assembly structure helps to ensure the stable operation of the filter element under high pressure environment and improve the reliability and safety of the system.

[0025] When the embodiment of the present application is in use, first, the sealing cover 5 in the air intake device is installed on the air intake port of the high-pressure air compressor through the one-way air intake valve. When the high-pressure air compressor performs an air intake action, the one-way air intake valve opens and the external air enters the flat head pipe 2, the internal threaded ring sleeve 3 and the columnar filter element 6 through the split air intake structure. Inside the columnar filter element 6, impurities and dust in the air will be captured by the filter element, while relatively clean air will enter the tube shell 4 through the columnar filter element 6, and enter the high-pressure air compressor through the sealing cover 5 and the one-way air intake valve, thereby realizing the air intake filtration function of the high-pressure air compressor. After the air intake device has been used for a period of time, the staff can manually The sealing cover 5 is manually screwed on and the end of the tube shell 4 is opened. Then the staff manually pulls out the columnar filter element 6 so that the end of the columnar filter element 6 is no longer connected to the outer wall of the cross ventilation disk 7 through the arc-shaped plug-in structure 8 until the columnar filter element 6 is completely pulled out. At this time, the staff takes out a new columnar filter element 6 and reinstalls the columnar filter element 6 into the tube shell 4 according to the reverse steps. Compared with the design of disassembling the air intake device as a whole, the operator can easily pull out the filter element for replacement without complicated disassembly process, and can timely discover and solve potential problems. Such a design reduces the difficulty of maintenance, while reducing the investment of manpower and time, and improving maintenance efficiency.
