Description

Technical Field

[0001] The present invention relates to the technical field of self-cleaning of water channels, and particularly to a self-cleaning device for a cooling water channel of an air compressor. Background Art

[0002] When the air compressor is in use, it needs to be cooled by the cooling water channel inside the air compressor and an external water circulation device. However, metal particles generated by the water circulation device or the air compressor will be produced in the long-term used cooling water channel. Metal particles with a size of 0 to 200 μm can be ignored, while metal particles larger than 200 μm will affect the cooling water channel. By connecting a filtering device to the water circulation device to filter the metal particles in the coolant, it will inevitably hinder the movement of the coolant. When the air compressor is working, if the water circulation is not timely and the cooling cannot be carried out in time, it will cause a greater burden on it. Therefore, a self-cleaning filter that does not cause too much hindrance to the cooling of the air compressor needs to be set up. Summary of the Invention

[0004] To solve the above technical problems, the present invention adopts the following technical solutions: The present invention provides a self-cleaning device for a cooling water channel of an air compressor, including a fitting circular plate, a water guide pipe, and a plurality of filtering monomers. The water guide pipe and the plurality of filtering monomers are evenly distributed along the circumferential direction of the fitting circular plate, and the tops of the water guide pipe and the plurality of filtering monomers are coplanar with the bottom of the water outlet pipe. A rotating mechanism for driving the fitting circular plate to rotate is arranged at the bottom of the fitting circular plate.

When the coolant is not cleaned, the water outlet pipe is connected to the water guide pipe, the water inlet insertion pipe is inserted into the bottom of the water guide pipe, and the flow sensor is in an unactivated state. When the coolant is cleaned, the water outlet pipe is connected to the filtering monomer, the water inlet insertion pipe is inserted into the bottom of the filtering monomer, and the flow sensor is in an activated state.

[0005] Preferably, it further includes a filter element self-cleaning device including a bidirectional pulling mechanism, a water supply pipe, a water storage pipe, and a reciprocating extrusion mechanism. The water supply pipe is vertically slidably installed directly above the filter unit and is connected to the water supply machine. The water storage pipe is vertically slidably installed directly below the filter unit. The bidirectional pulling mechanism is used to drive the water supply pipe and the water storage pipe to clamp on both sides of the filter unit. The reciprocating extrusion mechanism is fixedly installed at the bottom of the water storage pipe and is used to reciprocally extrude the inside of the water storage pipe. As shown in the figure, a closing circular plate for sealing is provided at the bottom of the filter unit, and an extendable bottom frame that can slide vertically is fixedly provided on the outer edge of the closing circular plate. A push bar for pushing the extendable bottom frame is provided inside the water storage pipe.

[0006] Preferably, the filter unit includes a sintered filter cartridge and a receiving cylinder. The sintered filter cartridge is inserted into the inside of the receiving cylinder. Water permeable holes for liquid to pass through are provided on the outer edge of the receiving cylinder. A circular notch for the closing circular plate to cover is provided at the bottom of the receiving cylinder. A guide groove for the extendable bottom frame to slide is provided on the outer edge of the circular notch. The receiving cylinder is provided with a limiting strip for limiting the bottom of the closing circular plate. When filtering and cleaning the coolant, the water inlet insertion tube is sleeved on the outer edge of the receiving cylinder, and the top of the water inlet insertion tube abuts against the fitting circular plate. A gap is left between the outer edge of the receiving cylinder and the inner edge of the water inlet insertion tube. When cleaning the filter unit, the water storage pipe is sleeved on the outer edge of the receiving cylinder, and the top of the water storage pipe abuts against the fitting circular plate.

[0007] Preferably, a circular ring is provided at the top of the outer edge of the receiving cylinder. The circular ring is connected to the fitting circular plate, and an annular card slot is provided on the circular ring. When the water outlet pipe is pressed on the top of the filter unit, the bottom of the water outlet pipe will contact the circular ring. When the water supply pipe is pressed on the top of the filter unit, the bottom of the water supply pipe will be clamped in the annular card slot.

[0008] Preferably, a connecting bent plate fixedly connected to the water inlet insertion tube is fixedly provided on the outer edge of the water storage pipe.

[0009] Preferably, the reciprocating extrusion mechanism includes a piston plate inside the water storage pipe and a linear pushing mechanism for pushing the piston plate to move up and down. A liquid discharge pipe is provided on the side wall of the water storage pipe. The linear pushing mechanism is fixedly installed on the water storage pipe. When reciprocally extruding the coolant inside the water storage pipe, the piston plate reciprocates above the liquid discharge pipe. When it is necessary to discharge the coolant inside the water storage pipe, the piston plate is located below the liquid discharge pipe.

[0010] Preferably, the bidirectional pulling mechanism includes an electric push rod, an upper hinge rod, and a lower hinge rod. One end of the upper hinge rod is hinged to the water supply pipe, and the other end of the upper hinge rod is hinged to the output end of the electric push rod. One end of the lower hinge rod is hinged to the water storage pipe, and the other end of the lower hinge rod is hinged to the electric push rod. The included angle between the lower hinge rod and the axis of the electric push rod is smaller than the included angle between the upper hinge rod and the axis of the electric push rod.

[0012] Preferably, retractable bellows are provided at the top of the water supply pipe and the bottom of the water intake insertion pipe.

[0013] The beneficial effects of the present invention are as follows: When the self-cleaning device for the cooling water channel of the air compressor does not perform cleaning work, it is connected between the water outlet pipe and the water intake insertion pipe through the guide water pipe, and will not impede the water circulation, that is, it avoids affecting the cooling process of the air compressor. When it is necessary to clean the cooling water channel, it is connected to the water outlet pipe and the water intake insertion pipe through the filter unit to filter metal particles larger than 200 μm, and the filtering time is short, only the time required for the coolant to circulate once, and it will not cause a large burden on the cooling of the air compressor. And multiple filter units are provided. When the flow sensor senses a decrease in the water flow passing through, it means that the filter unit is blocked, and the next filter unit can be automatically switched to avoid affecting the water flow and further avoiding affecting the cooling of the air compressor.

[0014] In order to reduce the replacement frequency of the filter unit, through the filter element self-cleaning device, the inside of the filter unit is cleaned. During cleaning, the push bar on the water storage pipe can automatically open the cover round plate at the bottom of the filter unit, and then through the cooperation of the reciprocating extrusion mechanism, the water flow can enter along the bottom of the filter unit and move up and down inside the filter unit, thereby flushing the side wall of the filter unit to achieve a better cleaning effect. And during the cleaning process, the movement of the water flow can drive the metal particles to automatically discharge along the bottom of the filter unit. Description of the Drawings

Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Embodiment 1: The present invention provides a self-cleaning device for the cooling water channel of an air compressor, which includes a fitting circular plate 2, a water guide pipe 4, and a plurality of filter monomers 3. The water guide pipe 4 and the plurality of filter monomers 3 are evenly distributed along the circumferential direction of the fitting circular plate 2, and the tops of the water guide pipe 4 and the plurality of filter monomers 3 are coplanar with the bottom of the water outlet pipe 1b. When the fitting circular plate 2 drives the water guide pipe 4 and the plurality of filter monomers 3 to rotate and switch positions, the switched water guide pipe 4 or filter monomer 3 can be attached to the bottom of the water outlet pipe 1b, so that the liquid flowing out of the water outlet pipe 1b can enter the water guide pipe 4 or filter monomer 3 without leakage. A rotating mechanism for driving the fitting circular plate 2 to rotate is provided at the bottom of the fitting circular plate 2. The rotating mechanism can be a rotating motor, a dividing plate, or a rotating oil cylinder. The water intake insertion pipe 7 is located directly below the water outlet pipe 1b and is used to insert into the water outlet of the bottom of the filter monomer 3 or the water guide pipe 4. A lifting mechanism for driving up and down is provided on the water intake insertion pipe 7. The lifting mechanism can be an electric push rod. A solenoid valve 1c is provided on the water outlet pipe 1b, and a flow sensor 6 is provided on the water intake insertion pipe 7;

[0030] When the coolant is not cleaned, the water outlet pipe 1b is connected to the water guide pipe 4, the water intake insertion pipe 7 is inserted into the bottom of the water guide pipe 4, and the flow sensor 6 is in an unactivated state; since the filter monomer 3 needs to filter metal particles larger than 200um, it will inevitably cause the filter monomer 3 to impede the flow of the coolant. Therefore, when filtering is not performed, the water outlet pipe 1b and the water intake insertion pipe 7 are connected through the water guide pipe 4 to avoid impeding the coolant.

[0031] When cleaning the coolant, the water outlet pipe 1b is connected to the filter monomer 3, the water intake insertion pipe 7 is inserted into the bottom of the filter monomer 3, and the flow sensor 6 is in an activated state. When the flow sensor 6 detects a decrease in the amount of coolant passing through per unit time, the flow sensor 6 will transmit a signal to the controller, and the controller will control the fitting circular plate 2 to rotate and switch, so that the next filter monomer 3 moves for replacement, and the used filter monomer 3 is marked, so that when filtering the coolant next time, the filter monomer 3 is directly skipped.

[0032] When cleaning and filtering are required, the fitting circular plate 2 will inevitably rotate and switch the positions of the water guide pipe 4 and the filter monomers 3. At this time, the controller will control the solenoid valve 1c to close, so that the coolant will not leak during the switching. After the position switching is completed, the solenoid valve 1c will be controlled to open.

[0033] Embodiment 2: The difference from Embodiment 1 is that in order to achieve self-cleaning of the filter monomer 3, increase the service life of the filter monomer 3, and reduce the replacement times of the filter monomer 3, such as Figures 5 - 7As shown in the figure, it further includes a filter element self-cleaning device 8, which includes a bidirectional pulling mechanism 8a, a water supply pipe 8b, a water storage pipe 8c, and a reciprocating extrusion mechanism 8d. The water supply pipe 8b is vertically slidably installed directly above the filter unit 3. The water supply pipe 8b is connected to a water supply machine. Clean water is added along the water supply pipe 8b through the water supply machine, so that the clean water fills the inside of the filter unit 3 and the water storage pipe 8c. The water storage pipe 8c is vertically slidably installed directly below the filter unit 3. The bidirectional pulling mechanism 8a is used to drive the water supply pipe 8b and the water storage pipe 8c to clamp on both sides of the filter unit 3. The reciprocating extrusion mechanism 8d is fixedly installed at the bottom of the water storage pipe 8c. That is, the bidirectional pulling mechanism 8a can drive the water supply pipe 8b and the water storage pipe 8c to approach or move away from the filter unit 3. When cleaning the filter unit 3, it can be clamped on the filter unit 3. The reciprocating extrusion mechanism 8d is used to reciprocally extrude the inside of the water storage pipe 8c. Through the reciprocating extrusion of the reciprocating extrusion mechanism 8d, the solution located in the filter unit 3 is moved up and down, thereby cleaning the inner wall of the filter unit 3. As Figure 7 shown in the figure, a closing circular plate 3a for sealing and closing is provided at the bottom of the filter unit 3. The bottom of the filter unit 3 is sealed by the closing circular plate 3a. When the closing circular plate 3a is opened, the water entering the inside of the filter unit 3 can be discharged along the gap opened by the closing circular plate 3a. An extension bottom frame 3b that can slide vertically is fixedly provided on the outer edge of the closing circular plate 3a. As Figure 6 shown in the figure, a push bar 8c1 for pushing the extension bottom frame 3b is provided inside the water storage pipe 8c. During the process of covering the water storage pipe 8c on the bottom of the filter unit 3, the push bar 8c1 will push the extension bottom frame 3b upward, so that the closing circular plate 3a is opened. The entire cleaning process of the filter element self-cleaning device 8 is as follows: The bidirectional pulling mechanism 8a pulls the water supply pipe 8b and the water storage pipe 8c to clamp on both sides of the filter unit 3. The push bar 8c1 pushes the closing circular plate 3a to open. Clean water is added along the water supply pipe 8b through the water supply machine, so that the clean water fills the inside of the filter unit 3 and the water storage pipe 8c. Then, through the reciprocating extrusion of the reciprocating extrusion mechanism 8d, the solution located in the filter unit 3 is moved up and down, thereby cleaning the inner wall of the filter unit 3.

[0034] As Figure 5 and Figure 8As shown in the figure, the filtering unit 3 includes a sintered filter cartridge 3c and a receiving cylinder 3d. The sintered filter cartridge 3c is inserted into the interior of the receiving cylinder 3d. Water-permeable holes for liquid to pass through are provided on the outer edge of the receiving cylinder 3d. A circular notch 3e for the cover plate 3a to cover is provided at the bottom of the receiving cylinder 3d. By covering the circular notch 3e with the cover plate 3a, the sealing of the bottom of the receiving cylinder 3d is achieved. A guide groove 3f for the sliding of the extended bottom frame 3b is provided on the outer edge of the circular notch 3e. The extended bottom frame 3b is slidably guided through the guide groove 3f, so that the extended bottom frame 3b moves vertically upward. The receiving cylinder 3d is provided with a limiting bar 3h for limiting the bottom of the cover plate 3a, so that the cover plate 3a cannot slide downward. The cover plate 3a slides upward, thereby opening the circular notch 3e;

[0035] When filtering and cleaning the coolant, the water inlet pipe 7 is sleeved on the outer edge of the receiving cylinder 3d. The top of the water inlet pipe 7 abuts against the fitting plate 2. A gap is left between the outer edge of the receiving cylinder 3d and the inner edge of the water inlet pipe 7; when the water inlet pipe 7 is sleeved on the outer edge of the receiving cylinder 3d, the coolant discharged along the side wall of the sintered filter cartridge 3c can enter the water inlet pipe 7 along this gap.

[0036] When cleaning the filtering unit 3, the water storage pipe 8c is sleeved on the outer edge of the receiving cylinder 3d. The top of the water storage pipe 8c abuts against the fitting plate 2. During cleaning, since the cover plate 3a is opened, the cleaning water can enter the filtering unit 3 along the circular notch 3e at the bottom of the filtering unit 3. The outer edge of the water storage pipe 8c can be in contact with the outer edge of the receiving cylinder 3d or a gap can be left.

[0037] As Figure 3 、 Figure 5 and Figure 8 As shown in the figure, a circular ring is provided at the top of the outer edge of the receiving cylinder 3d. The circular ring is connected to the fitting plate 2. The circular ring can be fixedly connected to the fitting plate 2 or in contact connection with the fitting plate 2. An annular card slot 3j is provided on the circular ring. When the water outlet pipe 1b is pressed on the top of the filtering unit 3, the bottom of the water outlet pipe 1b will contact the circular ring. When the water supply pipe 8b is pressed on the top of the filtering unit 3, the bottom of the water supply pipe 8b will be clamped in the annular card slot 3j.

[0038] As Figure 9 As shown in the figure, a connecting bent plate 8e fixedly connected to the water inlet pipe 7 is fixedly provided on the outer edge of the water storage pipe 8c. By providing the connecting bent plate 8e, when the water storage pipe 8c moves up and down, the water inlet pipe 7 can be driven to move up and down at the same time, so that the connecting bent plate 8e replaces the lifting mechanism and reduces the cost.

[0039] As Figure 6As shown, the reciprocating extrusion mechanism 8d includes a piston plate 8d1 located inside the water storage pipe 8c and a linear pushing mechanism 8d2 for pushing the piston plate 8d1 to move up and down. A liquid discharge pipe 8c2 is provided on the side wall of the water storage pipe 8c. The linear pushing mechanism 8d2 is fixedly installed on the water storage pipe 8c, so that when the water storage pipe 8c moves, it can drive the reciprocating extrusion mechanism 8d to move up and down together;

[0040] When the coolant in the water storage pipe 8c is extruded up and down, the piston plate 8d1 reciprocates above the liquid discharge pipe 8c2, so that when the piston plate 8d1 moves, the cleaning liquid will not be discharged along the liquid discharge pipe 8c2, and through the movement of the piston plate 8d1, the cleaning liquid cleans the inner wall of the sintered filter cartridge 3c;

[0041] When it is necessary to discharge the coolant in the water storage pipe 8c, the piston plate 8d1 is located below the liquid discharge pipe 8c2. Without the blockage of the piston plate 8d1, the coolant in the water storage pipe 8c can enter the liquid discharge pipe 8c2. The linear pushing mechanism 8d2 can be an electric push rod or a cam drive module.

[0042] As Figure 10 and Figure 11 shown, the two-way pulling mechanism 8a includes an electric push rod 8a1, an upper hinge rod 8a2 and a lower hinge rod 8a3. One end of the upper hinge rod 8a2 is hinged to the water supply pipe 8b, and the other end of the upper hinge rod 8a2 is hinged to the output end of the electric push rod 8a1. One end of the lower hinge rod 8a3 is hinged to the water storage pipe 8c, and the other end of the lower hinge rod 8a3 is hinged to the electric push rod 8a1. The included angle between the axis of the lower hinge rod 8a3 and the axis of the electric push rod 8a1 is smaller than the included angle between the axis of the upper hinge rod 8a2 and the axis of the electric push rod 8a1, so that when the output end of the electric push rod 8a1 is pushed out, the distance that the lower hinge rod 8a3 drives the water storage pipe 8c to move downward is greater than the distance that drives the water supply pipe 8b to move upward. By reducing the distance that the water supply pipe 8b moves upward, the vertical area occupied by the drive of the two-way pulling mechanism 8a is reduced, and the distance that the water storage pipe 8c moves downward is larger to avoid the extended chassis 3b during rotation.

[0043] As Figure 10 shown, guide plates 9 are provided on the outer edges of the water supply pipe 8b and the water storage pipe 8c, and guide posts 10 are slidably connected to the guide plates 9. By sliding the guide plates 9 along the guide posts 10, the vertical sliding guidance of the water supply pipe 8b and the water storage pipe 8c is realized.

[0044] Shrinkable bellows are provided at both the top of the water supply pipe 8b and the bottom of the water intake insertion tube 7. Through the bellows, the flow sensor 6 will not be jammed when moving downward, and the water supply pipe 8b will not be jammed when moving upward.

[0045] During use, when cooling the air compressor 1, the coolant in the cooling water channel of the air compressor 1 will enter along the water inlet pipe 1a and then discharge along the water outlet pipe 1b. The discharged coolant will pass through the water guide pipe 4 and the water diversion insertion pipe 7.

[0046] When self-cleaning of the coolant is required, the two-way pulling mechanism 8a drives the water diversion insertion pipe 7 and the water storage pipe 8c to descend, and the water supply pipe 8b ascends. Then, the rotating mechanism drives the fitting circular plate 2 to rotate to switch the positions of the filter element 3 and the water guide pipe 4. After the switching is completed, the two-way pulling mechanism 8a is reset. The water outlet pipe 1b is connected to the filter element 3, the water diversion insertion pipe 7 is inserted into the bottom of the filter element 3, and the flow sensor 6 is in the startup state. The coolant passes through the filter element 3, so that the coolant is filtered and cleaned. When the flow sensor 6 detects a decrease in the amount of coolant passing through per unit time, the flow sensor 6 will transmit a signal to the controller, and the controller will control the fitting circular plate 2 to rotate and switch, so that the next filter element 3 moves to replace it, and the used filter element 3 is marked, so that when the coolant is filtered next time, this filter element 3 is directly skipped.

[0047] And when the filter element 3 needs to be cleaned, the two-way pulling mechanism 8a pulls the water supply pipe 8b and the water storage pipe 8c to clamp on both sides of the filter element 3, and the push bar 8c1 pushes the covering circular plate 3a to open. Clean water is added along the water supply pipe 8b through the water supply machine, so that the clean water fills the inside of the filter element 3 and the water storage pipe 8c. Then, the reciprocating extrusion mechanism 8d reciprocally extrudes, so that the solution in the filter element 3 moves up and down, thereby cleaning the inner wall of the filter element 3. After the cleaning is completed, the piston plate 8d1 moves below the drain pipe 8c2, so that the used clean water is automatically discharged.

[0048] This self-cleaning device for the cooling water channel of the air compressor, when not performing cleaning work, connects the water outlet pipe and the water diversion insertion pipe through the water guide pipe, and will not hinder the water circulation, that is, it avoids affecting the cooling process of the air compressor. When the cooling water channel needs to be cleaned, the filter element is connected to the water outlet pipe and the water diversion insertion pipe, filters metal particles larger than 200 μm, and the filtering time is short. The required time is only one circle of coolant circulation, and it will not cause a large burden on the cooling of the air compressor. And there are multiple filter elements. When the flow sensor senses a decrease in the water flow passing through, it means that the filter element is blocked, and the next filter element can be automatically switched to avoid affecting the water flow and further avoiding affecting the cooling of the air compressor.

[0049] In order to reduce the frequency of replacing the filtering monomer, the inside of the filtering monomer is cleaned through a filter element self-cleaning device. During cleaning, the push bar on the water storage pipe can automatically open the closing circular plate at the bottom of the filtering monomer, and then through the cooperation of the reciprocating extrusion mechanism, water can enter along the bottom of the filtering monomer and move up and down inside the filtering monomer, thereby flushing the side wall of the filtering monomer to achieve a better cleaning effect. Moreover, during the cleaning process, the movement of the water can drive the metal particles to automatically discharge along the bottom of the filtering monomer.

[0050] Obviously, those skilled in the art can make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these modifications and variations.
