Description

Technical Field

[0001] This utility model relates to the technical field of screw air compressor cleaning equipment, specifically to a screw air compressor oil removal device. Background Technology

[0002] Screw air compressors are pre-configured units requiring only a single power and compressed air connection, and feature a built-in cooling system, greatly simplifying installation. Screw air compressors consistently provide high-quality compressed air to various industries due to their high efficiency, maintenance-free operation, and high reliability. However, current methods for cleaning screw air compressors involve running the compressor for a few minutes until the oil reaches room temperature, then turning it off, opening the oil filler cap, pouring in compressor cleaner, tightening the cap, and running the compressor for 30 minutes to remove oil. During this cleaning process, some oil spills out with the cleaner, causing oil buildup on the compressor casing and preventing thorough cleaning.

[0003] Currently, utility model patent CN220005125U discloses a screw air compressor oil removal device, including a treatment box. The treatment box houses the screw air compressor assembly, with mounting seats at both ends. One mounting seat has a support mechanism between it and the treatment box, while the other mounting seat has a rotating mechanism. A mounting mechanism connects the mounting seat to the screw air compressor assembly. This screw air compressor oil removal device thoroughly removes oil stains from both the inside and outside of the screw air compressor, ensuring effective subsequent use.

[0004] However, the existing screw air compressor oil removal device mentioned above requires the screw air compressor to be placed vertically between two mounting bases and squeezed for positioning before cleaning can be performed. The process is cumbersome and laborious. Therefore, we propose a screw air compressor oil removal device. Utility Model Content

[0005] The purpose of this utility model is to provide a screw air compressor oil removal device, which has the advantages of simple operation and convenient use, and solves the problem that the existing screw air compressor oil removal devices are relatively cumbersome and laborious to use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an oil removal device for a screw air compressor, comprising a base plate, an oil removal tank fixedly installed at the front end of the top of the base plate, a liquid storage tank fixedly installed at the rear end of the top of the base plate, upright plates fixedly connected to both the front and rear ends of the bottom of the oil removal tank, a liquid spray plate fixedly installed at the upper end of one side of the upright plate, a pump fixedly installed at the bottom of the liquid storage tank, an external cleaning pipe connected between the liquid outlet of the pump and the right side of the liquid spray plate, an internal cleaning branch pipe provided at one end of the liquid spray plate, and support seats fixedly installed at both the left and right ends of the bottom of the oil removal tank.

[0007] Preferably, casters are installed at both the left and right ends of the bottom of the base plate.

[0008] Preferably, a drain pipe is provided at the lower left end of the degreasing tank, and a manual valve body is provided at one end of the drain pipe.

[0009] Preferably, the end of the internal cleaning branch pipe away from the liquid spray plate is provided with a connector, and both the external cleaning pipe and the internal cleaning branch pipe are provided with a manual sealing valve body at one end.

[0010] Preferably, a through groove is formed on the inner surface of the lower end of the support base, and a movable toothed plate with a through hole on its inner surface is slidably connected to the inner side of the through groove. Arc-shaped limiting plates are fixedly connected to both the left and right ends of the inner side of the support base. A lower arc-shaped positioning seat is slidably connected between the arc-shaped limiting plate and the inner side of the support base. An arc-shaped toothed plate that meshes with the movable toothed plate is fixedly connected to the middle end of the outer surface of the lower arc-shaped positioning seat.

[0011] Preferably, an upper arc-shaped pressure plate is hinged to the rear end of the top of the lower arc-shaped positioning seat, an anti-slip pressure pad is bonded to the inner side of the upper arc-shaped pressure plate, a screw air compressor body is provided between the anti-slip pressure pad and the lower arc-shaped positioning seat, and a positioning screw that is threadedly connected to the lower arc-shaped positioning seat is provided at the front end of the upper arc-shaped pressure plate.

[0012] Preferably, the left and right ends of the inner cavity of the degreasing tank are movably connected by bearings to rotating rods that pass through the through holes of the movable toothed plate. A drive roller is fixedly connected to the middle end of the outer surface of the rotating rod. A reciprocating groove is opened on the outer surface of the drive roller. Guide protrusions that slide in the reciprocating groove are fixedly connected to the front and rear ends of the top of the inner side of the through hole of the movable toothed plate. A sprocket is fixedly connected to the front end of the outer surface of the two rotating rods. A chain is sleeved on the outer side of the sprocket.

[0013] Preferably, a drive motor is fixedly installed on the left end of the front of the degreasing tank, and the output end of the drive motor is fixedly connected to the front end of the rotating rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, through the setting of the support base, can support both ends of the screw air compressor body that needs to be cleaned, avoiding the cumbersome operation of vertical placement. Then, connect the connector of one end of the internal cleaning branch pipe to the oil inlet of the screw air compressor body, and after opening the corresponding manual sealing valve, the external controller starts the pump to send the cleaning agent in the liquid tank into the screw air compressor body, thereby realizing the ability to remove oil stains from the screw air compressor body. After closing the corresponding manual sealing valve, open the other manual sealing valve, and the pump can send the cleaning agent in the liquid tank into the liquid spray plate, which is sprayed outward from the nozzle. The sprayed cleaning agent can clean the outer surface of the screw air compressor body to remove oil stains, making this device convenient to use and easy to operate.

[0016] 2. This utility model, through the setting of the support base, allows the upper arc-shaped pressure plate to rotate upward around the hinge end after the screw air compressor body is placed inside the corresponding lower arc-shaped positioning seat. Then, tightening the positioning screw connects the upper arc-shaped pressure plate and the lower arc-shaped positioning seat into a whole. With the assistance of the anti-slip pressure pad, the position of the screw air compressor body can be limited. When the screw air compressor body needs to be externally degreased, the external controller turns on the drive motor. With the assistance of the sprocket and chain, the drive motor can drive two rotating parts. The rotating rod rotates, which in turn drives the drive roller to rotate. The drive roller then forces the guide protrusion to slide within the reciprocating groove. During the sliding of the guide protrusion, the moving toothed plate moves back and forth within the through groove. With the assistance of the arc-shaped limiting plate, the moving toothed plate, through the meshing connection of the arc-shaped toothed plate, drives the lower arc-shaped positioning seat to swing within the support seat. This, combined with the liquid spray plates set on both the front and rear sides, enables comprehensive cleaning during the swinging motion of the screw air compressor body. It is easy to use and has a good oil removal effect. Attached Figure Description

Then, the positioning screw 17 is tightened so that the upper arc-shaped pressure plate 18 and the lower arc-shaped positioning seat 19 are connected into a whole. With the assistance of the anti-slip pressure pad 16, the position of the screw air compressor body 7 can be limited. When the screw air compressor body 7 needs to be degreased externally, the external controller turns on the drive motor 6. With the assistance of the sprocket 22 and the chain 14, the drive motor 6 can drive the two rotating rods 13. The rotating rod 13 rotates, which drives the drive roller 23 to rotate. The drive roller 23 rotates, which forces the guide protrusion 24 to slide in the reciprocating track groove 25. During the sliding of the guide protrusion 24, the moving toothed plate 21 moves back and forth in the through groove 27. With the assistance of the arc-shaped limiting plate 26, the moving toothed plate 21, through the meshing arc-shaped toothed plate 20, drives the lower arc-shaped positioning seat 19 to swing in the support seat 11.
