Description

Technical Field

[0001] The utility model relates to the field of fertilizer production, in particular to a novel screw air compressor. Background Art

[0002] In the field of fertilizer production, screw air compressors are widely used in the production process of nitrogen fertilizer, phosphate fertilizer, potash fertilizer and other fertilizers to provide compressed air and gas treatment. Screw air compressors provide the required compressed air for reactions, transportation and mixing.

[0003] When a threaded rod air compressor needs to be installed in a humid or changeable environment, it is difficult to adjust the height in time, which will cause the bottom of the machine to be insufficiently close to the ground, thus causing moisture problems. The moisture at the bottom of the machine body may not only cause the metal parts of the machine to rust, reducing the overall durability of the machine, but may also cause electrical components to become damp, increasing the failure rate and safety hazards. Therefore, there is a possibility that the bottom of the air compressor casing will be corroded. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1 - Figure 4 As shown, a novel screw air compressor includes a screw air compressor housing 1, a support mechanism 2 and a dehumidification mechanism 3, wherein the support mechanism 2 is fixedly connected to the lower surface of the screw air compressor housing 1, and the dehumidification mechanism 3 is fixedly connected to the air inlet of the screw air compressor housing 1. The support mechanism 2 includes a fixed frame 204 fixedly connected to the lower surface of the screw air compressor housing 1, and the inner wall of the fixed frame 204 is rotatably connected with two groups of bidirectional threaded rods 210. The dehumidification mechanism 3 includes a filter frame 306 fixedly connected to the outer surface of the screw air compressor housing 1, and the inner wall of the filter frame 306 is slidably connected with the sliding frame 304. The outer surface of the bidirectional threaded rod 210 is threadedly connected with two groups of sliding blocks 208, and the outer surfaces of the sliding blocks 208 are hinged with connecting plates 209, and the other ends of the connecting plates 209 are hinged with knobs 202.

[0024] In order to adjust the distance between the screw air compressor housing 1 and the ground, the upper surface of the knob 202 is fitted with the lower surface of the fixed frame 204, and the four corners of the lower surface of the screw air compressor housing 1 are fixedly connected with universal wheels 201, which facilitate the movement of the screw air compressor housing 1 and thus facilitate the adjustment of the position of the screw air compressor housing 1. One end of the bidirectional threaded rod 210 passes through the outer surface of the fixed frame 204 and is fixedly connected with the knob 202, and the other end of the bidirectional threaded rod 210 passes through the outer surface of the fixed frame 204. The surfaces are fixedly connected with a sprocket 207, and the outer surface of the sprocket 207 is meshed with a chain 206. The knob 202 is rotated by using an external electric wrench, and the rotation of the knob 202 drives the sprocket 207 to rotate, so that the two groups of bidirectional threaded rods 210 can rotate synchronously. A sliding groove 211 is provided on the inner wall of the fixed frame 204, and the outer surface of the sliding groove 211 is slidably connected with the outer surface of the sliding block 208. The sliding groove 211 can easily reduce the force on the bidirectional threaded rod 210, thereby facilitating the reduction of the burden on the bidirectional threaded rod 210.

[0025] It is worth mentioning that the knob 202 is rotated using an external electric wrench, so that the bidirectional threaded rod 210 rotates and drives the two sets of fixed frames 204 to slide in opposite directions. The sliding of the fixed frame 204 drives one end of the connecting plate 209 to rotate, so that the other end of the connecting plate 209 drives the knob 202 to move downward. By adjusting the distance between the two sets of fixed frames 204, it is convenient to adjust the angle between the connecting plate 209 and the knob 202, and then it is convenient to adjust the distance between the lower surface of the screw air compressor casing 1 and the ground, which can reduce the direct contact between the air compressor and the wet ground, thereby reducing the occurrence of moisture entering the machine through the bottom, and solving the problem of corrosion caused by moisture.

[0026] In order to filter the moisture in the air, the inner wall of the sliding frame 304 is filled with a desiccant 307, such as activated alumina or silica gel, which can absorb moisture in the air, and the outer surface of the sliding frame 304 is slidably connected to the limiting frame 305, and the limiting frame 305 is fixedly connected to the inner wall of the filter frame 306. The limiting frame 305 is embedded with a magnet block 308 on the side away from the sliding frame 304, and the outer surface of the magnet block 308 is adsorbed with the iron frame 301, and the outer surface of the iron frame 301 is fixedly connected with the filter net 303. The magnet block 308 facilitates the adsorption of the outer surface of the iron frame 301, and then facilitates the disassembly of the iron frame 301. The iron frame 301 is slidably connected to the inner wall of the filter frame 306, and the side of the iron frame 301 away from the limiting frame 305 is fixedly connected with a fixed pull rod 302. By pulling the fixed pull rod 302, the iron frame 301 and the magnet block 308 can be separated, and then the filter net 303 can be cleaned.

[0027] It is worth mentioning that the sliding frame 304 facilitates the regular replacement of the desiccant 307 in the sliding frame 304, so that the desiccant 307 can absorb moisture in the air to prevent the occurrence of high humidity in the screw air compressor casing 1. By pulling the fixed rod 302, the iron frame 301 and the magnet block 308 are separated, thereby facilitating the cleaning of the filter 303.

[0028] Working principle: The position of the screw air compressor housing 1 can be easily adjusted through the universal wheel 201. After adjusting to the appropriate position, use an external electric wrench to turn the knob 202. The rotation of the knob 202 drives the two-way threaded rod 210 to rotate. The rotation of the two-way threaded rod 210 drives the sprocket 207 to rotate. The two groups of two-way threaded rods 210 rotate synchronously through the chain 206. The rotation of the two-way threaded rod 210 drives the two groups of fixed frames 204 to slide in opposite directions. The sliding of the fixed frame 204 drives one end of the connecting plate 209 to rotate, so that the other end of the connecting plate 209 drives the knob 202 to move downward, so that the lower end of the knob 202 contacts the ground, which is convenient for adjusting the screw. The lower surface of the air compressor housing 1 is supported, and by adjusting the distance between the two sets of fixed frames 204, it is convenient to adjust the angle between the connecting plate 209 and the knob 202, and then it is convenient to adjust the distance between the lower surface of the screw air compressor housing 1 and the ground, thereby improving the ventilation of the lower surface of the screw air compressor housing 1. By sliding the sliding frame 304, it is convenient to regularly replace the desiccant 307 in the sliding frame 304, so that the desiccant 307 can absorb moisture in the air to prevent the occurrence of high humidity in the screw air compressor housing 1. By pulling the fixed pull rod 302, the iron frame 301 and the magnet block 308 are separated, thereby facilitating the cleaning of the filter 303.
