Description

Technical Field

[0001] This utility model relates to the field of air filter technology, and in particular to an air filter for a gas compressor. Background Technology

[0002] The air filter of a gas compressor is a crucial component of the compressor system. Its primary function is to clean the intake air, preventing dust, dirt, moisture, and other impurities from entering the compressor's interior, thereby protecting its internal components and ensuring normal operation. The air filter's role extends beyond filtering impurities from the air; it also improves the compressor's efficiency and extends its lifespan.

[0003] In traditional technology, air filters in gas compressors are typically connected to the intake and delivery pipes using threaded connections. However, this threaded connection design has certain drawbacks, especially under high pressure, where the connection is prone to loosening and detachment. Long-term use can also lead to thread wear or external vibrations. Particularly in high-pressure gas environments, the compressor's operation generates significant airflow impact forces, causing excessive stress on the connection points between the intake and delivery pipes, ultimately resulting in threaded connection failure. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides an air filter for a gas compressor, aiming to improve the problem that the air filter of a gas compressor in the traditional technology usually uses a threaded connection to connect with the air intake and air delivery pipes, which leads to the pipes becoming loose and falling off, causing safety hazards.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an air filter for a gas compressor, comprising a controller, a connecting base fixedly connected to the bottom of the controller, an air inlet shell fixedly connected to the bottom of the connecting base, an air inlet side provided on one side of the air inlet shell, an air outlet side provided on the other side of the air inlet shell, an installer fixedly connected to the outside of both the air inlet side and the air outlet side, a sleeve slidably connected inside the installer, an air supply pipe fixedly connected to the side of the sleeve away from the installer, a slot provided on the outside of the sleeve, an outer shell slidably connected to the bottom of the air inlet shell, a locking mechanism provided inside the installer for stably installing the air supply pipe, and a connecting mechanism provided outside the air inlet shell for quickly assembling and disassembling the outer shell;

[0006] The engaging mechanism includes a slide rod slidably connected to the top of the installer. A slider is fixedly connected to the bottom of the slide rod, and a return spring is fixedly connected to the bottom of the slider. Connecting rods are rotatably connected to both sides of the slider. U-shaped brackets are rotatably connected to the bottom of both connecting rods. Locking rods are fixedly connected to the bottom of both U-shaped brackets. Clamps are fixedly connected between the two locking rods, and both clamps engage with the locking groove.

[0007] As a further description of the above technical solution:

[0008] The slider is slidably connected inside the mounter, and both connecting rods are slidably connected inside the mounter.

[0009] As a further description of the above technical solution:

[0010] The bottom of the return spring is fixedly connected inside the mounter.

[0011] As a further description of the above technical solution:

[0012] A push handle is fixedly connected to the top of the slide rod.

[0013] As a further description of the above technical solution:

[0014] An air filter element is fixedly connected inside the housing, and a throttle valve is fixedly connected to the bottom of the housing.

[0015] As a further description of the above technical solution:

[0016] The connecting mechanism includes a mounting shell, which is fixedly connected to the outside of the air intake shell. A compression spring is fixedly connected inside the mounting shell. A limit block is fixedly connected to the side of the compression spring near the air intake shell. A pin is fixedly connected inside the limit block. A locking hole is opened on the outside of the outer shell. The pin passes through the outside of the air intake shell and engages with the locking hole.

[0017] As a further description of the above technical solution:

[0018] A fixing box is fixedly connected to the top of the mounting shell, a sliding plate is slidably connected inside the fixing box, a baffle plate is fixedly connected to the bottom of the sliding plate, and the bottom of the baffle plate abuts against the top of the limiting block.

[0019] As a further description of the above technical solution:

[0020] The limiting block is slidably connected inside the mounting housing, the pin passes through both ends of the mounting housing, and the pin is fixedly connected to a handle at some points away from the limiting block.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, when connecting the gas pipeline, the push handle is used to push the slide rod downwards, causing it to push the slider to compress the return spring. When the slider moves downwards, the connecting rod drives the U-shaped frame, causing the two clamps to separate relative to each other. After the pipe sleeve is slid into the installer, the push handle is released. The return force of the return spring pushes the slider upwards, and the connecting rod causes the two clamps to move relative to each other and engage with the slot for fixation. This achieves the effect of stably connecting the gas pipeline through the engaging mechanism, enhances the stability of the pipeline connection, avoids safety accidents, and improves the practicality of the device.

[0023] 2. In this utility model, when the air filter needs to be replaced, the handle is pulled outward to push the pin rod, causing the limiting block to compress the spring and retract into the mounting shell. When the limiting block moves, the baffle plate automatically falls due to gravity, preventing the limiting block from moving forward. At this time, the shell can be removed to replace the air filter. After replacement, the shell is slid into the bottom of the air intake shell and the baffle plate is pulled up by the sliding plate. The spring force pushes the limiting block, causing the pin rod to move forward and re-engage with the locking hole. This achieves the effect of quickly disassembling and assembling the shell to replace the air filter through the connecting mechanism, improving the efficiency of air filter use and the practicality of the device.

[0036] Specifically, the locking rod 15 inside the locking mechanism drives the clamp 16 to engage and fix with the slot 9, thereby improving the stability of the gas pipeline 8 connection.

[0037] Reference Figure 1 and Figure 6 - Figure 7 The connecting mechanism includes a mounting shell 22, which serves to fix the internal structure.

[0039] Working principle: When connecting the gas pipe 8, push the slide bar 10 downward by pushing the push handle 17 to push the slider 11 to compress the return spring 12. When the slider 11 moves downward, it drives the U-shaped frame 14 through the connecting rod 13, causing the two clamps 5 to drive the two clamps 16 to separate relative to each other. After the pipe sleeve 7 is slid into the installer 6, release the push handle 17. The return force of the return spring 12 pushes the slider 11 to move upward. Through the connecting rod 13, the two clamps 15 drive the two clamps 16 to gather relative to each other and engage with the slot 9 to fix it.

[0040] When the air filter 19 needs to be replaced, pull the pin 25 outward by the handle 29 to cause the limit block 24 to compress the compression spring 23 and retract it into the mounting shell 22. When the limit block 24 moves, the baffle plate 28 will fall automatically due to gravity, preventing the limit block 24 from moving forward. At this time, the shell 18 can be removed to replace the air filter 19. After the replacement is completed, slide the shell 18 into the bottom of the air intake shell 3 and pull up the baffle plate 28 by the slide plate 27. The rebound force of the compression spring 23 will push the limit block 24 to move the pin 25 forward and re-engage with the locking hole 21 to fix it.
