Technical Field
[0001] The utility model belongs to the technical field of air compressors, and in particular relates to a screw air compressor. Background Art
[0002] A screw air compressor is an air compressor that comes in two types: single-screw and twin-screw. The design of a twin-screw air compressor is more reasonable and advanced. It overcomes the shortcomings of a single-screw air compressor, such as imbalance and easy bearing wear. It has the advantages of long life, low noise, and greater energy saving. Screw air compressors are required when conveying materials with air in pig farms.
[0003] In order to prevent air impurities from entering the casing of commonly used screw air compressors, filters are required to filter the air entering the air compressor. In actual use, the filter element of the air compressor filter is usually replaced regularly. However, due to different environments and usage frequencies, the regular replacement of filter elements can easily lead to problems such as overuse or underuse of the filter element. Utility Model Content
[0004] The purpose of the utility model is to provide a screw air compressor, which can make the service life of the filter element more reasonable, so as to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a screw air compressor, comprising an air compressor housing and an air intake pipe, the air intake pipe being fixedly connected to one side of the top end of the air compressor housing, an air outlet pipe being provided on one side of the bottom end of the air compressor housing, a filter box being provided at the top end of the air intake pipe, and an indicator component for reflecting the air pressure in the air intake pipe being provided on the side wall of the air intake pipe, one end of the indicator component being fixedly connected to the side wall of the air intake pipe.

[0007] Furthermore, an inspection window is provided at the top of the air compressor housing.
[0008] Furthermore, the air compressor housing is internally rotatably connected to two correspondingly arranged screws, the two screws are transmission-connected, one end of the air compressor housing is fixedly connected to a motor, and the output shaft of the motor is fixedly connected to one end of one of the screws.
[0009] Furthermore, the marking assembly includes a cylinder fixedly connected to the side wall of the air intake pipe, one end of the cylinder is fixedly connected to a sealing plate, and a through hole is provided in the middle of the sealing plate.
[0010] Furthermore, a piston is slidably connected to the inside of the cylinder, one end of the piston is fixedly connected to a display column, the display column passes through the through hole in the middle of the sealing plate, one end of the piston is fixedly connected to a standard spring, and one end of the standard spring is fixedly connected to one end of the sealing plate.
[0011] Furthermore, the side wall of the display column is provided with scale lines.
[0012] Compared with the prior art, the beneficial effect of the present invention is that after the filter box filters out the dust in the air, the dust accumulates on the filter element on the filter box, making it difficult for air to pass through the filter box.

The filter element of the filter box can be replaced according to the instructions of the marking component, so that the service life of the filter element is more reasonable.

[0019] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.
[0020] like Figure 1-3As shown, a screw air compressor includes an air compressor housing 1 and an air intake pipe 2, the air intake pipe 2 is fixedly connected to one side of the top end of the air compressor housing 1, an air outlet pipe 3 is provided on one side of the bottom end of the air compressor housing 1, a filter box 4 is provided at the top end of the air intake pipe 2, and an indicator component 5 for reflecting the air pressure in the air intake pipe 2 is provided on the side wall of the air intake pipe 2, and one end of the indicator component 5 is fixedly connected to the side wall of the air intake pipe 2.
[0021] According to the above structure, when in use, after starting the screw air compressor, external air enters the interior of the air compressor housing 1 through the air outlet pipe 3, and the air is discharged through the air outlet pipe 3 after being compressed. The air is filtered through the filter box 4 before entering the air outlet pipe 3. After the filter box 4 filters out the dust in the air, the dust accumulates on the filter element on the filter box 4, making it difficult for the air to pass through the filter box 4. Since the power of the air compressor remains unchanged during operation, the air pressure inside the air outlet pipe 3 will be reduced. At this time, the marking component 5 can reflect the air pressure inside the air outlet pipe 3. The filter element of the filter box 4 can be replaced according to the indication of the marking component 5, so that the service life of the filter element is more reasonable.
[0022] like Figure 1 and 3 As shown, a support base 11 is symmetrically provided at the bottom end of the air compressor housing 1, an inspection window 12 is provided at the top end of the air compressor housing 1, and two correspondingly provided screws 13 are rotatably connected inside the air compressor housing 1. The two screws 13 are transmission-connected, and one end of the air compressor housing 1 is fixedly connected to a motor 14, and the output shaft of the motor 14 is fixedly connected to one end of one of the screws 13.
[0023] According to the above structure, during operation, the motor 14 drives the two screws 13 to rotate in opposite directions, and the air inside the air compressor housing 1 is discharged through the air outlet pipe 3, so that a negative pressure is generated inside the air compressor housing 1, and the external air enters the interior of the air compressor housing 1 through the air outlet pipe 3. The setting of the inspection window 12 facilitates the inspection of the parts inside the air compressor housing 1.
[0024] like Figure 4 As shown, the marking component 5 includes a cylinder 51 fixedly connected to the side wall of the intake pipe 2, one end of the cylinder 51 is fixedly connected to a sealing plate 55, the middle part of the sealing plate 55 is provided with a through hole, the inside of the cylinder 51 is slidably connected to a piston 52, one end of the piston 52 is fixedly connected to a display column 53, the display column 53 passes through the through hole in the middle of the sealing plate 55, one end of the piston 52 is fixedly connected to a standard spring 54, and one end of the standard spring 54 is fixedly connected to one end of the sealing plate 55.
[0025] According to the above structure, during operation, as the use time of the filter box 4 increases, the mesh of the filter element of the filter box 4 is gradually clogged with dust, thereby reducing the air intake smoothness, while the power of the motor 14 remains unchanged. As the degree of clogging of the mesh of the filter element of the filter box 4 increases, the air pressure inside the air intake pipe 2 becomes lower. During operation, when the air pressure inside the air intake pipe 2 decreases, the piston 52 slides toward the direction close to the air intake pipe 2 under the action of the external atmospheric pressure, and the display column 53 retracts toward the inside of the cylinder 51. The degree of clogging of the mesh of the filter element of the filter box 4 is reflected according to the retraction amount of the display column 53. When the display column 53 retracts to the set value, the filter element of the filter box 4 can be replaced.
[0026] like Figure 1 As shown, in order to intuitively reflect the retraction amount of the display column 53, scale lines are set on the side wall of the display column 53.
[0027] The working principle of the present invention is as follows: when in use, after starting the screw air compressor, the motor 14 drives the two screws 13 to rotate in opposite directions, and the air inside the air compressor housing 1 is discharged through the air outlet pipe 3, so that a negative pressure is generated inside the air compressor housing 1, and the external air enters the interior of the air compressor housing 1 through the filter box 4. The provision of the inspection window 12 facilitates the inspection of the parts inside the air compressor housing 1. During operation, as the filter box 4 is used for a longer time, the mesh of the filter element of the filter box 4 is gradually clogged with dust, thereby reducing the smoothness of the air intake. However, the power of the motor 14 remains unchanged. As the degree of clogging of the mesh of the filter element of the filter box 4 increases, the air pressure inside the air intake pipe 2 becomes lower. During operation, when the air pressure inside the air intake pipe 2 decreases, the piston 52 slides in the direction closer to the air intake pipe 2 under the action of the external atmospheric pressure, and the display column 53 retracts into the interior of the cylinder 51. The retraction amount of the display column 53 reflects the degree of clogging of the mesh of the filter element of the filter box 4. When the display column 53 retracts to the set value, the filter element of the filter box 4 can be replaced.
