Description

Technical Field

[0001] The utility model relates to the field of air compressors, in particular to an air compressor for trimer acid processing. Background Art

[0002] Trimer acid, commonly referring to sodium tripolyphosphate or related compounds such as cyanuric acid, has a wide range of uses in industrial processing, such as as a detergent ingredient, water treatment agent, preservative, and food additive. Drying of raw materials or products is a crucial step in trimer acid production. Air compressors can provide dry, compressed air for drying equipment to remove moisture and ensure product quality. Especially for drying processes that require precise humidity control, the use of an air compressor in conjunction with the dryer is essential.

[0003] When using existing air compressors, in order to prevent external air from contaminating the trimer acid raw materials, a filter is usually installed at the air inlet port of the air compressor. However, after using the filter for a period of time, dust easily clogs the filter holes. At this time, the filter needs to be replaced. During the replacement process, production may need to be interrupted, thereby affecting work efficiency. In addition, sometimes the staff does not discover the blockage of the filter in time, resulting in a decrease in the air entering the air compressor. The reduced air flow may extend the drying time of the trimer acid raw materials and reduce the drying efficiency of the trimer acid raw materials. Summary of the Invention

[0004] Therefore, in order to solve the above-mentioned shortcomings, the present invention provides an air compressor for trimer acid processing to solve the above-mentioned technical problems.

DETAILED DESCRIPTION

[0025] In order to further explain the technical solution of the present invention, specific embodiments are described in detail below.

[0026] like Figure 1 As shown, the utility model provides an air compressor for trimer acid processing, comprising an air compressor body 1, an air inlet end 2 is provided on the air compressor body 1, and the air inlet end 2 is used to introduce external air;

[0027] Specifically, when in use, the exhaust end of the air compressor body 1 is connected to the cooler in the trimer acid raw material drying and processing equipment, so that the compressed air generated by the air compressor body 1 is cooled by the cooler, and the compressed air enters the air dryer for use.

[0028] like Figures 2 to 6 As shown, this embodiment further includes a filter mechanism 3 provided on the air compressor body 1. The filter mechanism 3 includes a fixed box 31 locked and fixed to the air compressor body 1, an air intake pipe 33 installed on the left end surface of the fixed box 31, and an air supply channel 32 opened in the fixed box 31 and flush with the air intake end 2 and the inner side of the air intake pipe 33.

[0029] A circular rotating plate 34 is rotatably mounted on the inner side of the fixed box 31 and is located between the air supply channel 32 and the air inlet pipe 33. The circular rotating plate 34 can rotate vertically within the fixed box 31. A driving assembly is provided on the inner bottom of the fixed box 31 to provide driving force for the rotation of the circular rotating plate 34.

[0030] A wind speed sensor 39 is fixedly secured to the inner wall of the air supply passage 32. The wind speed sensor 39 is used to detect the flow rate of air entering the air compressor body 1.

[0031] The circular rotating plate 34 is provided with three positioning holes 35 distributed in an annular pattern at equal intervals. A filter cartridge 36 is disposed in each positioning hole 35. The inner side of the upper filter cartridge 36 is connected to the inner side of the air supply channel 32 and the air inlet pipe 33. The filter cartridge 36 is used to filter the air entering the air compressor body 1.

[0032] The wind speed sensor 39 is electrically connected to the controller 315 installed on the fixed box 31, so that the opening and closing of the wind speed sensor 39 can be controlled by the controller 315;

[0033] In this embodiment, the filter cartridge 36 includes a cartridge body 361 locked and fixed in the positioning hole 35, and a metal filter screen 362, a synthetic fiber filter screen 363, and an activated carbon filter screen 364 locked and fixed in the cartridge body 361 from left to right. The inner side of the upper end of the cartridge body 361 is flush with the inner side of the air supply channel 32 and the air intake pipe 33, facilitating multiple filtration of the air through the metal filter screen 362, the synthetic fiber filter screen 363, and the activated carbon filter screen 364 in the upper end of the cartridge body 361.

[0034] The metal filter 362 faces the inner side of the air inlet pipe 33 , and the activated carbon filter 364 faces the inner side of the air supply channel 32 ;

[0035] The inner diameter of the mesh holes of the synthetic fiber filter 363 is smaller than the inner diameter of the mesh holes of the metal filter 362, so that the synthetic fiber filter 363 can filter the air more finely.

[0036] In this embodiment, an inspection port 37 is provided on the left end surface of the fixed box 31. The inner side of the inspection port 37 is connected to the lower end cylinder 361. The inner diameter of the inspection port 37 is larger than the outer diameter of the cylinder 361, so that the lower end cylinder 361 can be easily disassembled and replaced through the inspection port 37.

[0037] A sealing plate 38 is locked and fixed inside the inspection port 37, and the sealing plate 38 seals the inside of the inspection port 37 to reduce external dust from entering the fixed box 31 through the inspection port 37;

[0038] In this embodiment, the metal filter 362 is made of stainless steel, which has strong corrosion resistance and longer service life;

[0039] Specifically, during use, the external air enters the air supply channel 32 through the air inlet pipe 33 and passes through the inner side of the upper cylinder 361. The air is filtered multiple times by the metal filter 362, the synthetic fiber filter 363 and the activated carbon filter 364 inside the cylinder 361. Among them, the activated carbon filter 364 can effectively absorb harmful gases and odor molecules in the air to achieve air purification, so as to prevent harmful gases in the external air from affecting the quality of the trimer acid raw material.

[0040] In this embodiment, the drive assembly includes a mounting groove 311 provided at the bottom inner side of the fixed box 31, a motor 312 locked and fixed inside the mounting groove 311, a gear 313 sleeved on the output shaft of the motor 312, and a tooth groove 310 provided along the circumferential side surface of the circular rotating plate 34. The inner side of the tooth groove 310 and the gear 313 are mutually intertwined.

[0041] An angle sensor 314 is installed on the inner wall of the mounting groove 311. The angle sensor 314 is used to detect the rotation angle of the output shaft of the motor 312. The detection end of the angle sensor 314 is coaxially connected to the output shaft of the motor 312. The motor 312 and the angle sensor 314 are both electrically connected to the controller 315.

[0042] The inner width of the tooth groove 310 is greater than the thickness of the gear 313, and a gap is set between the left and right end surfaces of the inner side of the tooth groove 310 and the left and right end surfaces of the gear 313, respectively, to reduce friction between the gear 313 and the inner wall of the tooth groove 310, thereby reducing wear on the gear 313 and the inner wall of the tooth groove 310;

[0043] Specifically, when in use, when air flows in the air supply channel 32, the air flow speed is detected by the wind speed sensor 39, and the information is transmitted to the controller 315. When the air flow speed is detected to be lower than the preset value, it is determined that the metal filter 362, the synthetic fiber filter 363 or the activated carbon filter 364 in the cylinder 361 is blocked. At this time, the controller 315 controls the starting motor 312 to drive the gear 313 to rotate, and the gear 313 cooperates with the tooth groove 310 to drive the circular rotating plate 34 to rotate, and the circular rotating plate 34 drives each positioning hole 35 and the filter cylinder 36 The rotation angle of the output shaft of the motor 312 is detected by the angle sensor 314, thereby indirectly judging the rotation angle of the gear 313 and the circular rotating plate 34. When the circular rotating plate 34 rotates 120°, the filter cartridge 36 is replaced, and the new filter cartridge 36 enters between the air supply channel 32 and the air inlet pipe 33. The new filter cartridge 36 is used to facilitate the air to stably pass through the filter cartridge 36 and enter the air compressor body 1, thereby improving the stability of the air compressor body 1 during use, and indirectly reducing the drying time of the trimer acid raw material and improving the drying efficiency of the trimer acid raw material.
