Description

Technical Field

[0001] The present application relates to the technical field of compressors, and in particular to a completely oil-free and water-lubricated single-screw process gas compressor. Background Art

[0002] A gas compressor is used to compress gas. Its structure is similar to that of a water pump. Most air compressors are reciprocating piston type, with rotating blades or screws. Noise control primarily utilizes mufflers, muffler tunnels, and sound insulation technologies. An air compressor consists of a pair of parallel, meshing male and female rotors (or screws) rotating within a cylinder, causing the air between the rotor teeth to undergo a periodic volumetric change. The air is then transported along the rotor axis from the intake side to the output side, completing the entire process of suction, compression, and exhaust in a screw compressor.

[0003] In cold seasons, when the existing process gas compressor is shut down, cold air will enter the box, causing the internal components of the box to freeze and be damaged, which will easily damage the process gas compressor and make the process gas compressor unstable. Utility Model Content

[0004] In order to improve the problem that when the compressor equipment is in a stopped state, cold air will enter the interior of the box, causing the internal parts of the box to freeze and be damaged, thereby making the process gas compressor prone to damage and unstable in use, the present application provides a fully oil-free and water-lubricated single-screw process gas compressor.

[0005] The present application provides a completely oil-free water-lubricated single-screw process gas compressor that adopts the following technical solution:

[0007] By adopting the above technical solution, a ventilation fan is arranged on the box body. When the compressor is started, the negative pressure generated inside the compressor is used to open the ventilation fan air inlet flap. When the compressor is stopped, the flap is closed, thereby preventing cold air from entering the box body when the equipment is stopped in the cold season, thereby reducing the possibility of internal components of the box being frozen in the cold season.

[0008] Preferably, a heating oil radiator and a water tank are also provided on the base.

[0009] By adopting the above technical solution, by setting up a heating oil radiator and a water storage tank, the temperature inside the unit can be kept ≥℃ and the unit can operate normally with water replenishment.

[0011] By adopting the above technical solution, a mounting frame is mounted on the ventilation fan, and then a filter is fixed in the mounting frame. When the compressor is running, air is drawn into the unit through the ventilation fan, and dust in the air is filtered out by the filter, thereby reducing the possibility of dust entering the unit from the inlet of the ventilation fan, causing dust to accumulate for a long time and causing damage to components in the unit.

[0012] Preferably, the inner bottom surface of the mounting frame is provided with an opening, the top plate can pass through the opening, the fixing member 1 includes a magnet 1 fixed on the inner top surface of the mounting frame, the top surface of the top plate is fixed with a magnet 2, and the magnet 1 and the side surfaces of the magnet 2 that are close to each other are attracted to each other.

[0013] By adopting the above technical solution, the top plate is pulled upward through the opening to attract the second magnet and the first magnet, thereby installing the filter in the installation frame.

[0014] Preferably, the through-hole is provided at both ends of the inner side surface of the through-hole away from the box body, the second fixing member includes a bolt inserted into the through-hole, the bolt is threadedly connected to the inner circumferential surface of the through-hole, the bottom plate is located in the through-hole, and the bolt is close to the end face of the box body and abuts against the side of the bottom plate.

[0015] By adopting the above technical solution, when the top plate is passed through the through opening to attract magnet 1 and magnet 2, the bottom plate moves into the through opening, and then the bolt is rotated so that the bolt presses the bottom plate into the through opening, thereby fixing the bottom plate in the through opening.

[0016] Preferably, grooves are provided on the relative inner sides of the mounting frame, the grooves are communicated with the through-port, a mounting groove is provided on the inner side of the groove away from the box body, an abutment plate is slidably provided in the mounting groove, a plurality of springs are fixed to the side of the abutment plate away from the box body, one end of the spring away from the abutment plate is fixed to the inner side of the mounting groove away from the box body, the two ends of the filter screen are respectively inserted into the two grooves, and the abutment plate abuts the filter screen against the inner side of the groove close to the box body.

[0017] By adopting the above technical solution, when the top plate is pulled upward through the opening, the two ends of the filter screen are respectively inserted into the two grooves, so that the abutment plate presses the filter screen against the inner side surface of the groove under the elastic force of the spring, thereby facilitating the installation of the filter screen in the installation frame, and the abutment plate fixes the two ends of the filter screen in the groove.

[0018] Preferably, two forklift holes are provided on the side surface of the base, and the forklift holes pass through the base along the width direction of the base.

[0019] By adopting the above technical solution, two forklift holes are opened on the side of the base, thereby facilitating the transportation of the compressor by using a forklift.

[0020] Preferably, hanging columns are fixed at both ends of the two side surfaces of the base.

[0021] By adopting the above technical solution, two hoisting columns are respectively fixed on the two sides of the base. When the compressor needs to be hoisted, it is convenient to hoist the compressor by tying the hoisting rope on the crane equipment to the hoisting columns.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By installing a ventilation fan on the box, when the compressor starts, the negative pressure generated inside the compressor is used to open the ventilation fan air inlet flap. When the compressor stops, the flap is closed, thus preventing cold air from entering the box when the equipment is stopped in cold seasons, thereby reducing the possibility of internal parts of the box being damaged by freezing in cold seasons;

[0024] 2. Install a mounting frame on the ventilation fan, and then fix the filter inside the mounting frame. When the compressor is running, the ventilation fan draws air into the unit, and the filter removes dust in the air. This reduces the possibility of dust entering the unit through the ventilation fan inlet, causing long-term accumulation of dust and damaging the components of the unit.

[0025] 3. When the top plate is passed through the through opening so that magnet 1 and magnet 2 are attracted to each other, the bottom plate moves into the through opening, and then the bolts are rotated so that the bolts press the bottom plate into the through opening, thereby fixing the bottom plate in the through opening.

A filter 32 is arranged in the mounting frame 3, and a top plate 33 is fixed to the top of the filter 32. The distance between the two end surfaces of the top plate 33 is smaller than the distance between the two ends of the filter 32. A second magnet 36 is fixed to the top surface of the top plate 33, and a first magnet 35 is fixed to the inner top surface of the mounting frame 3. The sides of the first magnet 35 and the second magnet 36 that are close to each other are attracted to each other. A bottom plate 34 is fixed to the bottom end of the filter 32, and a through opening 31 is provided on the inner bottom surface of the mounting frame 3.
