Description

Technical Field

[0001] The utility model relates to a twin-screw air compressor, belonging to the technical field of twin-screw air compressors. Background Art

[0002] The full name of a twin-screw air compressor is a twin-screw type air compressor, which is a twin-shaft positive displacement rotary air compressor. The compressor is directly driven by an electric motor to make the crankshaft generate a rotary motion, drive the connecting rod to make the piston generate a reciprocating motion, causing the change of the cylinder volume. Due to the change of the pressure in the cylinder, air enters the cylinder through the air intake valve after passing through the air filter (silencer). In the compression stroke, due to the reduction of the cylinder volume, the compressed air enters the air storage tank through the exhaust valve, the exhaust pipe and the one-way valve (check valve). Since twin-screw air compressors are currently widely used, it is of great significance to improve the new twin-screw air compressor.

[0003] According to the authorized patent CN202221893424.1, it can be known that in this patent, the dust filter cloth made of fibers can effectively prevent dust from easily entering the twin-screw air compressor along with the air and adhering to the internal components, and the accumulated dust over a long time is likely to cause a load on the twin-screw air compressor, thereby effectively improving the service life of the new twin-screw air compressor. The moving block with a clamping block and a connecting spring can make the installation and disassembly of the rear plate more convenient, thus effectively improving the work efficiency of maintenance personnel. However, although the filter cloth can prevent dust from entering the interior of the equipment, when too much dust adheres to the surface of the filter cloth, it will block the filter cloth, thereby affecting normal heat dissipation, and only dissipating heat through the heat dissipation holes has a relatively low efficiency and cannot quickly cool the interior of the equipment. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a twin-screw air compressor. The structure of the utility model is simple and easy to use, which can clean the dust adsorbed on the surface of the filter cloth and can accelerate the heat dissipation inside the equipment when cleaning, so as to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A twin-screw air compressor includes a device main body. A sealing plate is rotatably connected to the outside of the device main body. A controller is fixedly connected to the outside of the device main body. Heat dissipation holes are opened in the inner wall of the device main body. A cleaning mechanism is arranged on the outside of the device main body. A heat dissipation mechanism is fixedly connected to the outside of the device main body.

[0007] The cleaning mechanism includes a sliding groove, inside which a sliding rod is slidably connected. A moving block is fixedly connected to the outer side of the sliding rod. A reset spring is fixedly connected to the bottom of the sliding rod. A clamping ring is fixedly connected to the outer side of the moving block. A connecting rod is installed inside the clamping ring. A cleaning roller is rotatably connected to the outer side of the connecting rod. A positioning hole is formed inside the connecting rod.

An electric telescopic rod is fixedly connected to the outer side of the equipment main body. A lifting rod is fixedly connected to the bottom of the electric telescopic rod.

[0008] The heat dissipation mechanism includes a pushing rod. A power supply box is fixedly connected to the outer side of the equipment main body. A switch is fixedly connected to the outer side of the power supply box. A wire is fixedly connected to the outer side of the power supply box. A micro motor is fixedly connected to the outer side of the equipment main body. A rotating shaft is fixedly connected to the output end of the micro motor. A fan blade is fixedly connected to the outer side of the rotating shaft.

[0009] Furthermore, the sliding grooves are symmetrically distributed on the outer side of the equipment main body. The moving block is slidably connected to the outer side of the sliding groove. Through the setting of the sliding rod, the moving block can stably slide on the outer side of the sliding groove.

[0010] Furthermore, the bottom of the reset spring is fixedly connected to the inner bottom wall of the sliding groove. The cleaning roller is slidably connected to the outer side of the heat dissipation hole. Through the setting of the reset spring, the moving block can automatically return to its original position when not being squeezed.

[0011] Furthermore, the bottom of the compression spring is fixedly connected to the top of the movable tube. The bottom of the stabilizing rod is located inside the positioning hole. By clamping the stabilizing rod inside the positioning hole, the cleaning roller is installed between the two moving blocks.

[0012] Furthermore, the electric telescopic rod and the lifting rod are symmetrically distributed on the outer side of the equipment main body, and the lifting rod is directly above the force-receiving rod. The controller is electrically connected to the electric telescopic rod. By driving the lifting rod to move up and down through the electric telescopic rod, a pushing effect can be exerted on the force-receiving rod.

[0013] Furthermore, the pushing rod is directly above the switch, and a spring is fixedly connected inside the switch. By moving the pushing rod downward, the switch can be squeezed, enabling the power supply box to be powered on. When the switch is not squeezed, the switch will close again under the action of the spring.

[0014] Furthermore, the power supply box is electrically connected to the micro motor through the wire. The fan blade is located on the outer side of the heat dissipation hole. When the switch starts the power supply box, the micro motor will be started, thereby driving the fan blade on the outer side of the rotating shaft to rotate.

[0015] The beneficial effects of the present utility model are as follows:

[0016] (1) By providing a device main body in the present utility model, heat dissipation holes are opened in the inner wall of the device main body. When it is necessary to clean the dust adsorbed on the surface of the heat dissipation holes, the electric telescopic rod is started through the controller, so that the electric telescopic rod drives the lifting rod to move downward. At this time, the force rod on the top of the moving block will be squeezed, causing the moving block to move outside the sliding groove. Through the cooperation of the moving block and the clamping ring, the connecting rod can drive the cleaning roller to slide outside the heat dissipation hole, and the dust adsorbed on the surface of the heat dissipation hole can be cleaned. When the lifting rod moves upward, under the action of the reset spring, the moving block returns to its original position, so that the cleaning roller moves up and down outside the heat dissipation hole, and the dust can be evenly cleaned. When it is necessary to clean the cleaning roller after a long time of work, at this time, the stabilizing rod moves upward inside the movable tube, so that the bottom of the stabilizing rod is pulled out from the positioning hole inside the connecting rod, and the cleaning roller can be disassembled. At this time, the cleaning roller can be cleaned for the next use.

[0017] (2) By providing a device main body in the present utility model, when the electric telescopic rod drives the lifting rod to move downward, it can drive the push rod to move downward. When it moves to the bottom, it will squeeze the switch outside the power supply box, so that the micro motor is started, and the micro motor drives the rotating shaft to rotate. Through the rotation of the rotating shaft, the fan blade is driven to rotate, and the generated wind will accelerate the air flow speed outside the heat dissipation hole, thereby accelerating the heat dissipation efficiency inside the device main body.

[0025] Example 1 Please refer to Figures 1-4 , the present invention provides a technical solution:

[0026] A twin-screw air compressor includes an equipment main body 1. A sealing plate 2 is rotatably connected to the outside of the equipment main body 1. A controller 3 is fixedly connected to the outside of the equipment main body 1. Heat dissipation holes 4 are opened in the inner wall of the equipment main body 1. A cleaning mechanism 5 is arranged on the outside of the equipment main body 1. A heat dissipation mechanism 6 is fixedly connected to the outside of the equipment main body 1. The cleaning mechanism 5 includes a sliding groove 51. A sliding rod 52 is slidably connected to the inside of the sliding groove 51. A moving block 53 is fixedly connected to the outside of the sliding rod 52. A return spring 54 is fixedly connected to the bottom of the sliding rod 52. A clamping ring 55 is fixedly connected to the outside of the moving block 53. A connecting rod 56 is installed inside the clamping ring 55. A cleaning roller 57 is rotatably connected to the outside of the connecting rod 56. A positioning hole 58 is opened in the inside of the connecting rod 56. A movable tube 59 is fixedly connected to the top of the clamping ring 55. A stabilizing rod 510 is movably connected to the inside of the movable tube 59. A compression spring 511 is fixedly connected to the outside of the stabilizing rod 510. A force-bearing rod 512 is fixedly connected to the top of the moving block 53. An electric telescopic rod 513 is fixedly connected to the outside of the equipment main body 1. A lifting rod 514 is fixedly connected to the bottom of the electric telescopic rod 513.

[0027] Specifically, as Figure 1As shown, the sliding grooves 51 are symmetrically distributed on the outside of the device main body 1. The moving blocks 53 are slidably connected to the outside of the sliding grooves 51. The bottom of the return spring 54 is fixedly connected to the inner bottom wall of the sliding groove 51. The cleaning roller 57 is slidably connected to the outside of the heat dissipation holes 4. The bottom of the compression spring 511 is fixedly connected to the top of the movable tube 59. The bottom of the stabilizing rod 510 is located inside the positioning hole 58. The electric telescopic rod 513 and the lifting rod 514 are symmetrically distributed on the outside of the device main body 1, and the lifting rod 514 is directly above the stress rod 512.

[0028] Furthermore: The setting of the sliding rod 52 enables the moving block 53 to stably slide on the outside of the sliding groove 51. The setting of the return spring 54 enables the moving block 53 to automatically return to its original position when not being squeezed. By engaging the stabilizing rod 510 inside the positioning hole 58, the cleaning roller 57 is installed between the two moving blocks 53. The controller 3 is electrically connected to the electric telescopic rod 513. Driving the lifting rod 514 to move up and down by the electric telescopic rod 513 can exert a pushing force on the stress rod 512.

[0029] In this implementation: By providing the device main body 1 with heat dissipation holes 4 opened in the inner wall of the device main body 1. When it is necessary to clean the dust adsorbed on the surface of the heat dissipation holes 4, the controller 3 is used to activate the electric telescopic rod 513, so that the electric telescopic rod 513 drives the lifting rod 514 to move downward. At this time, it will exert pressure on the stress rod 512 on the top of the moving block 53, causing the moving block 53 to move on the outside of the sliding groove 51. The cooperation of the moving block 53 and the clamping ring 55 enables the connecting rod 56 to drive the cleaning roller 57 to slide on the outside of the heat dissipation holes 4, and can clean the dust adsorbed on the surface of the heat dissipation holes 4.

When it is necessary to clean the cleaning roller 57 after a long time of work, at this time, the stabilizing rod 510 moves upward inside the movable tube 59, so that the bottom of the stabilizing rod 510 is pulled out from the positioning hole 58 inside the connecting rod 56, so that the cleaning roller 57 can be disassembled, and at this time, the cleaning roller 57 can be cleaned for future use.

[0030] Example 2 Please refer to Figure 1 、 Figure 2 And Figure 4, the difference between this embodiment and Embodiment 1 lies in that: the heat dissipation mechanism 6 includes a push rod 61, the outside of the device main body 1 is fixedly connected with a power supply box 62, the outside of the power supply box 62 is fixedly connected with a switch 63, the outside of the power supply box 62 is fixedly connected with a wire 64, the outside of the device main body 1 is fixedly connected with a micro motor 65, and the output end of the micro motor 65 is fixedly connected with a rotating shaft 66. A fan blade 67 is fixedly connected to the outside of the rotating shaft 66.

[0031] Specifically, as Figures 1-4 shown, the push rod 61 is located directly above the switch 63, and a spring is fixedly connected inside the switch 63. The power supply box 62 is electrically connected to the micro motor 65 through the wire 64, and the fan blade 67 is located outside the heat dissipation hole 4.

[0032] Furthermore: by moving the push rod 61 downward, the switch 63 can be squeezed, so that the power supply box 62 is energized. When the switch 63 is not squeezed, the switch 63 is closed again under the action of the spring. When the switch 63 starts the power supply box 62, the micro motor 65 will be started, thereby driving the fan blade 67 outside the rotating shaft 66 to rotate.

[0033] In this implementation scheme: by setting the device main body 1, when the electric telescopic rod 513 drives the lifting rod 514 to move downward, the push rod 61 can be driven to move downward. When it moves to the bottom, the switch 63 outside the power supply box 62 will be squeezed, so that the micro motor 65 is started, and the micro motor 65 drives the rotating shaft 66 to rotate. The rotation of the rotating shaft 66 drives the fan blade 67 to rotate, and the generated wind will accelerate the air flow speed outside the heat dissipation hole 4, thereby accelerating the heat dissipation efficiency inside the device main body 1.
