Description

Technical Field

[0001] This utility model belongs to the field of screw compressor technology, and specifically relates to a vertical permanent magnet variable frequency screw compressor. Background Technology

[0002] The vertical permanent magnet variable frequency screw compressor is a high-efficiency and energy-saving compressed air equipment. It combines a permanent magnet synchronous motor with variable frequency drive technology. Its vertical and compact structural design optimizes space occupation. Its core advantage lies in the variable frequency adjustment function, which can accurately match the air demand.

[0003] Screw compressors require drainage primarily because water vapor condenses into liquid water during air compression. If not drained promptly, this water emulsifies the lubricating oil, reduces its lubrication performance, and accelerates rotor and bearing wear. Simultaneously, moisture corrodes pipes and internal components, shortening equipment lifespan and affecting compressed air quality. Therefore, regular drainage is necessary. Effective heat dissipation is also crucial for screw compressors, as air compression generates significant heat. Failure to dissipate this heat promptly leads to a rapid temperature rise, causing a series of problems: high temperatures accelerate lubricating oil oxidation and deterioration, reducing lubrication performance and further exacerbating rotor and bearing wear. Water cooling is often used to dissipate heat in screw compressors. However, prolonged neglect of cleaning pipes and cooling components can result in scale buildup, reducing heat exchange efficiency. High-pressure air carrying condensate can effectively clean components. Therefore, it is essential to develop a structure that guides high-pressure gas and condensate to clean cooling pipes and components. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a vertical permanent magnet variable frequency screw compressor that allows for easy cleaning of heat dissipation pipes and components.

[0005] The objective of this utility model can be achieved through the following technical solution: A vertical permanent magnet variable frequency screw compressor includes a main support frame, a screw compressor body, a high-pressure gas tank, and a cooling unit. The screw compressor body, high-pressure gas tank, and cooling unit are all fixed to the main support frame. A drain pipe is provided at the bottom of the high-pressure gas tank. A heat dissipation plate is provided on the cooling unit, and several through-hole cooling pipes are provided on the heat dissipation plate. A connecting pipe is provided between the cooling pipes and the drain pipe. A cleaning component is provided inside the connecting pipe. A guide cone is provided on the cleaning component. A connecting rod is provided at the bottom of the guide cone. A fixed push plate is provided at the bottom of the connecting pipe. A snap-fit ​​notch is provided on the fixed push plate. A movable push plate is also provided inside the connecting pipe. An engaging protrusion is provided on the movable push plate, and several flow holes are provided on the movable push plate. The engaging protrusion and the snap-fit ​​notch engage with each other.

[0006] In the above-mentioned vertical permanent magnet variable frequency screw press, the side wall of the snap-fit ​​notch is provided with several limiting grooves, and the side plate of the biting protrusion is provided with several elastic rings, which are fitted into the limiting grooves.

[0007] In the above-mentioned vertical permanent magnet variable frequency screw press, the drain pipe is provided with an end nut, and a movable needle roller and an outer ring are provided between the end nut and the drain pipe. The connecting pipe is snapped onto the outer wall of the outer ring, and the end nut is provided with several engagement notches.

[0008] In the above-mentioned vertical permanent magnet variable frequency screw press, both the biting protrusion and the limiting groove are provided with guide rounded corners.

[0009] In the aforementioned vertical permanent magnet variable frequency screw compressor, a control valve is provided on the drain pipe.

[0010] In the above-mentioned vertical permanent magnet variable frequency screw compressor, a sealing ring is provided on the side wall of the guide cone, and the sealing ring abuts against the inner wall of the connecting pipe and the cooling pipe.

[0011] Compared with existing technologies, this vertical permanent magnet variable frequency screw compressor connects the drain pipe and the cooling pipe through a connecting pipe, providing a passage for the cleaning component. The movable push plate and the fixed push plate can carry condensate water and push it with high pressure gas to effectively clean the dirt on the cooling pipe and clean the cooling pipe, thus cleaning the cooling pipe at the same time as cleaning the condensate water.

A cleaning component 11 is installed inside the connecting pipe 2. The cleaning component 11 has a guide cone 10, and a connecting rod 12 is located at the bottom of the guide cone 10. A fixed push plate 14 is located at the bottom of the connecting pipe 2, and a snap-fit ​​notch 16 is provided on the fixed push plate 14. A movable push plate 17 is also installed inside the connecting pipe 2. The movable push plate 17 has an engaging protrusion 18 and several flow holes 20. The engaging protrusion 18 and the snap-fit ​​notch 16 engage with each other. Before use, the cleaning component 11 is placed inside the connecting pipe 2, and the movable push plate 17 is... 7. Place it at the drain pipe opening so that the engaging protrusion 18 is aligned with the fixed push plate 14. When in use, connect the drain pipe 9 and cooling pipe 5 to both ends of the connecting pipe 2, and open the drain pipe 9 so that the cooling water in the drain pipe 9 is drained from the flow hole 20 and the water in the high pressure gas tank 1. Then rotate the cooling pipe so that the engaging protrusion 18 is aligned with the snap-fit ​​notch 16. Under the push of the high pressure gas, the engaging protrusion 18 is fitted into the snap-fit ​​notch 16, and the fixed push plate 14 covers one side of the flow hole 20 to complete the seal.

The connecting pipe 2 is snapped onto the outer wall of the outer ring 25. The end nut 24 is provided with several engagement notches 23. During installation, after the outer ring 25 and the needle roller 13 are installed in place, the end nut 24 limits the outer ring 25 to prevent the outer ring 25 and the needle roller 13 from falling off. The connecting pipe 2 is fixed to the outer ring 25, making the rotation of the connection easier.

[0022] Preferably, both the engagement protrusion 18 and the limiting groove 15 are provided with guide radii 21.
