[0002] A compressor is a driven fluid machine that boosts low-pressure gas to high-pressure gas. When the pressure in the compressor is too high during use, it will automatically cut off the power and shut down for protection. However, the internal pressure of the compressor cannot be released in time, and it is easily affected by the environment and burst, posing certain safety hazards. In addition, when the compressor is in use, a mesh plate is usually installed to filter natural wind. The mesh plate and the compressor are mostly connected by welding or bolts. When the mesh plate is damaged or blocked, it is difficult to disassemble and clean it, increasing the maintenance workload. Utility Model Content

[0003] In order to overcome the above-mentioned defects, the utility model provides a compressor explosion-proof device which is easy to maintain, and solves the problem that the compressor will automatically cut off the power and shut down for protection when the pressure is too high during use. However, the internal pressure of the compressor cannot be released in time, and it is easy to burst due to environmental influences. In addition, when the compressor is in use, a mesh plate is usually installed to filter natural wind. The mesh plate and the compressor are mostly connected by welding or bolts.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The compressor explosion-proof device which is easy to maintain, by holding four handles and squeezing, four card strips are brought close to each other until the card strips are out of the card slots in the air inlet. At this time, the bracket is in an active state, and the filter plate can be removed from the compressor body by pulling out the bracket, so that the filter plate and the air holes can be cleaned conveniently. When installing the filter plate, the bracket is pushed into the air inlet. When the bracket no longer moves, the position of the card strip corresponds to the position of the card slot.

[0013] 2. The compressor explosion-proof device, which is easy to maintain, circulates gas through a buffer box. After the gas enters the buffer box, the pressure gauge can monitor the air pressure value to facilitate air pressure regulation. At the same time, the pressure sensor on the pressure gauge can transmit the monitoring signal to the controller in the compressor body. If the signal value is greater than the preset value, the solenoid valve opens and the gas is discharged from the exhaust pipe to reduce the pressure in the compressor body. If the signal value is less than the preset value, the solenoid valve closes and the gas in the buffer box is normally introduced into the compression tank from the one-way valve pipe, thereby effectively releasing the pressure inside the compressor body and playing an explosion-proof role.

DETAILED DESCRIPTION

[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] like Figure 1-4 As shown, the utility model provides a technical solution: a compressor explosion-proof device that is easy to maintain, comprising a compressor body 1, a compression tank 2 is installed at the bottom of the compressor body 1, two running wheels 11 are installed at the bottom of the compression tank 2, and a push handle 10 is installed on one side of the top of the compression tank 2. Through the mutual cooperation between the running wheel 11 and the push handle 10, the push handle 10 is lifted and the compression tank 2 is pushed to make the running wheel 11 roll on the ground, so as to facilitate the transfer of the device;

[0021] An air inlet 3 is provided on the compressor body 1, and a dust filter assembly 4 is installed in the air inlet 3. The dust filter assembly 4 includes a bracket 401, which is clamped in the air inlet 3. A filter plate 402 is provided in the bracket 401, and a plurality of air holes 403 are provided on the filter plate 402. A fixing block 6 is fixed in the middle of the bracket 401, and four positioning assemblies 5 are provided outside the fixing block 6. The positioning assembly 5 includes a clamping strip 501, and the clamping strip 501 is slidably connected in the bracket 401. The part of the clamping strip 501 embedded in the clamping slot 7 is of arc design, and the handle 502 is of L-shaped design. Because the handle 502 is provided, the four handles 502 are held and squeezed to make the four clamping strips 501 close to each other, so as to facilitate the synchronous adjustment of the positions of the four clamping strips 501, thereby improving the convenience of removing the bracket 401;

[0022] A handle 502 is fixed to the end of the clamping strip 501, and a spring 503 is fixed between the handle 502 and the fixing block 6. Because the spring 503 is provided, the elastic force of the spring 503 supports the clamping strip 501, so that the clamping strip 501 is inserted into the clamping slot 7, so as to facilitate the installation and fixation of the bracket 401 and the filter plate 402.

[0023] The inner wall of the air inlet 3 is provided with card slots 7 at the positions corresponding to the four card strips 501, and one end of the card strip 501 is carded in the card slot 7. An air duct 8 is connected to the compressor body 1, and an explosion-proof component 9 is connected to the end of the air duct 8. The bottom of the explosion-proof component 9 is connected to the compression tank 2. The explosion-proof component 9 includes a buffer box 901, and an exhaust pipe 904 is connected to one side of the buffer box 901. The exhaust pipe 904 is equipped with a solenoid valve 903. Because the exhaust pipe 904 is provided, the gas is discharged from the exhaust pipe 904 after the solenoid valve 903 is opened to reduce the pressure in the compressor body 1.

[0024] A pressure gauge 902 is connected to the bottom of the buffer box 901, and a pressure sensor 905 is installed outside the pressure gauge 902. Because the pressure sensor 905 is provided, the pressure sensor 905 can transmit the monitoring signal to the controller in the compressor body 1, so as to control the solenoid valve 903 to work;

[0025] The bottom of the buffer box 901 is connected to a one-way valve tube 906, and the bottom end of the one-way valve tube 906 is connected to the compression tank 2. Because of the one-way valve tube 906, the one-way valve tube 906 can guide the gas in the buffer box 901 into the compression tank 2 and prevent gas backflow.

[0026] The working principle of the utility model is:

[0027] When in use, hold the four handles 502 and squeeze them, and the four clips 501 are close to each other until the clips 501 are out of the slots 7 in the air inlet 3. Pull out the bracket 401 to remove the filter plate 402 from the compressor body 1. When installing the filter plate 402, push the bracket 401 into the air inlet 3. When the bracket 401 no longer moves, support the clips 501 with the elastic force of the spring 503 so that the clips 501 are stuck in the slots 7. The assembly of the filter plate 402 can be completed. After the gas enters the buffer box 901, the pressure gauge 902 can monitor the air pressure value. At the same time, the pressure sensor 905 on the pressure gauge 902 can transmit the monitoring signal to the controller in the compressor body 1. If the signal value is greater than the preset value, the solenoid valve 903 is opened and the gas is discharged from the exhaust pipe 904. If the signal value is less than the preset value, the solenoid valve 903 is closed, and the gas in the buffer box 901 is normally introduced into the compression tank 2 from the one-way valve pipe 906.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0029] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
