Description

Technical Field

[0001] The present invention belongs to the technical field of pipeline cleaning, and particularly relates to a condenser cleaning device. Background Art

[0002] The condenser of a refrigerating machine is a main component of the refrigerating machine equipment. Its main function is to cool the compressed high-temperature refrigerant (such as Freon), transfer its heat to the cooling water, and release it into the air through a cooling tower.

[0003] However, since the cooling water contains certain calcium and magnesium ions and dust, scale or dirt will form on the inner wall of the water pipe of the condenser during operation, which will reduce its heat transfer efficiency and affect the efficiency of the refrigerating machine. Therefore, it needs to be cleaned regularly.

[0004] At present, the main cleaning method is to dilute the descaling liquid and soak it, then use a wire brush to manually poke and brush, and finally rinse with water. The efficiency of poking and brushing and rinsing is low, it takes a long time, and the labor intensity of people is large. Taking the centrifugal refrigerating machine with a refrigerating capacity of 2907KW in our factory as an example, there are 948 copper tubes in its condenser. If manual brush poking + flushing is used, it takes 1.5 minutes to clean each tube, and it takes 23.7 hours of uninterrupted operation to clean a condenser. Summary of the Invention

[0005] The purpose of the present invention is to provide a condenser cleaning device. Through an air inlet pipe, the gun body and the main gun barrel, the sealing mechanism of the cleaning brush is blown, driving the cleaning brush to move in the copper tube of the condenser, and then using the brush body of the cleaning brush to clean the inner wall of the copper tube, improving the cleaning efficiency, saving cleaning time, and having strong practicability.

[0006] To achieve the above technical purpose, the technical solution adopted by the present invention is as follows:

[0007] A condenser cleaning device includes:

[0008] A cleaning brush, the cleaning brush includes a brush body and a sealing mechanism, and the sealing mechanism matches the inner wall of the copper tube of the condenser;

[0009] A cleaning gun, the cleaning gun includes a gun body, and a main gun barrel and an air pipe nozzle that are connected and communicated with each other are installed on the gun body;

[0010] The inner wall size of the main gun barrel matches the outer wall size of the sealing mechanism;

[0011] The water pipe nozzle is connected with an air inlet pipe communicated with a gas source.

[0012] Further limited, a connecting pipe is installed between the tracheal nozzle and the intake pipe, and a first control valve is installed between the intake pipe and the connecting pipe. The first control valve is used to control the on-off of the gas path between the intake pipe and the connecting pipe;

[0013] A button is installed on the cleaning gun, and the button is signal-connected to the first control valve.

[0014] With such a structural design, the action of the first control valve is controlled by the button on the cleaning gun, the on-off of the gas path between the intake pipe and the main barrel is controlled, and further the blowing on the cleaning brush is controlled. The structure is simple, the installation is convenient, and the practicability is strong.

[0015] Further limited, there are two cleaning guns.

[0016] With such a structural design, by setting the cleaning guns to two, at both ends of the condenser, in the way of alternating use of the two cleaning guns, the reciprocating blowing on the cleaning brush in the copper pipe is realized, so that the cleaning brush reciprocates in the copper pipe, improving the cleaning efficiency.

[0017] Further limited, the buttons of the two cleaning guns are both signal-connected to the same first control valve;

[0018] The first control valve is a three-position electromagnetic reversing valve;

[0019] When the button of the first cleaning gun is pressed and the three-position electromagnetic reversing valve is in the first position, the main barrel of the first cleaning gun is in communication with the intake pipe, and the main barrel of the second cleaning gun is in communication with the outside atmosphere;

[0020] When the button of the second cleaning gun is pressed and the three-position electromagnetic reversing valve is in the second position, the main barrel of the first cleaning gun is in communication with the outside atmosphere, and the main barrel of the second cleaning gun is in communication with the intake pipe;

[0021] When the buttons of the two cleaning guns are not pressed and the three-position electromagnetic reversing valve is in the third position, the intake pipe is in a disconnected state from the main barrels of the two cleaning guns.

[0022] With such a structural design, by jointly controlling the same first control valve with two buttons, the number of first control valves used can be reduced, the manufacturing cost can be saved, and the practicability is strong.

[0023] Further limited, a secondary barrel and a water pipe nozzle which are interconnected are also installed on the gun body;

[0024] The main barrel is arranged in parallel with the secondary barrel;

[0025] The distance dimension between the main barrel and the secondary barrel is the same as the distance dimension between two adjacent copper pipes;

[0026] One of the water pipe nozzles on the gun body is connected to a water inlet pipe that is in communication with a pressurized water source;

[0027] Another water pipe connection nozzle on the gun body is connected with a water outlet pipe.

[0028] This structural design, through the arrangement of the auxiliary gun barrel, water inlet pipe and water outlet pipe, allows the auxiliary gun barrel to rinse the cleaned copper tube after the main gun barrel is cleaned with a cleaning brush. While performing the secondary rinse, the main gun barrel can be aligned with the next copper tube for simultaneous cleaning, thereby improving cleaning efficiency.

[0029] At the same time, the auxiliary gun barrel of the cleaning gun connected to the water outlet pipe is used to receive the sewage after flushing the copper pipe to avoid sewage splashing, which is very practical.

[0030] It is further defined that a second control valve is installed on the water inlet pipe, and the second control valve is used to control the on-off of the water path in the water inlet pipe;

[0031] The button on the gun body connected to the water inlet pipe is connected to the second control valve signal;

[0032] The pressurized water source is a tap water pipeline.

[0033] This structural design, through the mutual cooperation of the second control valve, the button on the gun body connected to the water inlet pipe and the tap water pipe, when pressing the button on the gun body connected to the water inlet pipe, the air path between the air inlet pipe and the connecting pipe is connected, while controlling the on-and-off of the water path in the water inlet pipe, and cooperating with the pressurized water source of the tap water pipe to complete the flushing of the copper pipe without the need for additional control, easy operation and strong practicality.

[0034] It is further defined that an annular groove is provided on the inner wall of the free end of the main barrel, and the diameter of the annular groove matches the outer diameter of the copper tube.

[0035] This structural design, through the setting of the annular groove, allows the free end of the main barrel to be directly mounted on the copper tube, completing the radial positioning between the main barrel and the copper tube, making it more convenient to use and more practical.

[0036] It is further defined that there are two brush bodies, the two brush bodies are coaxially connected, and the sealing mechanism is located between the two brush bodies.

[0037] This structural design, by arranging brush bodies at both ends of the sealing mechanism, can ensure that no matter which end of the cleaning brush is inserted into the copper tube, the brush body will first contact the copper tube relative to the sealing mechanism, that is, the brush body first brushes the copper tube and then contacts the sealing mechanism, reducing the possibility of the sealing mechanism being stuck in the copper tube due to the scale in the copper tube not being cleaned, and is more practical.

[0038] Further limit that a threaded blind hole is formed on one of the brush bodies, and a threaded post is fixedly arranged on the other brush body;

[0039] The threaded post is screwed into the threaded blind hole;

[0040] The sealing mechanism is a sealing ring.

[0041] With such a structural design, through the screwing connection of the threaded post and the threaded blind hole, the fixed connection between the two brush bodies is completed, and the sealing ring serving as the sealing mechanism is fixed between the two brush bodies. The structure is simple, and it is convenient to replace the sealing ring after long-term use, with strong practicability.

[0042] Further limit that a number of hard bristles are arranged on the brush body.

[0043] With such a structural design, the inner wall of the copper pipe is cleaned by using the hard bristles instead of the brush body contacting the inner wall of the copper pipe. The structure is simple and the cleaning effect is good; among them, the hard bristles can be copper wires or nylon wires.

[0044] The invention adopting the above technical solution has the following advantages:

[0045] 1. Through the air inlet pipe, the gun body and the main gun barrel, the sealing mechanism of the cleaning brush is blown, driving the cleaning brush to move in the copper pipe of the condenser, and then using the brush body of the cleaning brush to clean the inner wall of the copper pipe, improving the cleaning efficiency, saving the cleaning time, and having strong practicability;

[0046] 2. By controlling the action of the first control valve through the button on the cleaning gun, the on-off of the air path between the air inlet pipe and the main gun barrel is controlled, and then the blowing of the cleaning brush is controlled. The structure is simple, the installation is convenient, and the practicability is strong;

[0047] 3. By setting two cleaning guns, at both ends of the condenser, in the way of alternating use of the two cleaning guns, the reciprocating blowing of the cleaning brush in the copper pipe is realized, so that the cleaning brush moves back and forth in the copper pipe, improving the cleaning efficiency;

[0048] 4. By jointly controlling the same first control valve with two buttons, the number of first control valves used can be reduced, the manufacturing cost can be saved, and the practicability is strong;

[0049] 5. Through the setting of the secondary gun barrel, the water inlet pipe and the water outlet pipe, after the main gun barrel uses the cleaning brush to clean the copper pipe, the secondary gun barrel can be used to flush the copper pipe that has been cleaned. While the secondary flushing is in progress, the main gun barrel can be aligned with the next copper pipe and the cleaning can be carried out synchronously, improving the cleaning efficiency;

[0050] At the same time, the secondary gun barrel of the cleaning gun connected with the water outlet pipe is used to receive the sewage after flushing the copper pipe, avoiding the splashing of sewage, and having strong practicability;

[0051] 6. Through the mutual cooperation of the second control valve, the button on the gun body connected to the water inlet pipe, and the tap water pipe, when pressing the button on the gun body connected to the water inlet pipe to connect the gas path between the air inlet pipe and the connecting pipe, the on-off of the water path in the water inlet pipe is controlled, and with the pressurized water source of the tap water pipe, the flushing of the copper pipe is completed without additional control, which is convenient to operate and has strong practicability;

[0052] 7. By arranging brush bodies at both ends of the sealing mechanism, no matter which end the cleaning brush is inserted into the copper pipe, the brush body will contact the copper pipe first relative to the sealing mechanism, that is, the brush body will brush the copper pipe first and then contact the sealing mechanism, reducing the possibility that the sealing mechanism is stuck in the copper pipe due to the scale in the copper pipe not being cleaned, and has strong practicability.

[0069] As Figures 1 to 7 shown, a condenser cleaning device of the present invention includes:

[0070] Cleaning brush 2, the cleaning brush 2 includes a brush body 21 and a sealing mechanism 22, and the sealing mechanism 22 is matched with the inner wall of the copper pipe 10 of the condenser 1;

[0071] Cleaning gun 3, the cleaning gun 3 includes a gun body 31, and a main barrel 32 and an air pipe nozzle that are connected to each other are installed on the gun body 31;

[0072] The inner wall size of the main barrel 32 is matched with the outer wall size of the sealing mechanism 22;

[0073] The water pipe nozzle is connected to an air inlet pipe 4 that communicates with a gas source.

[0074] A connecting pipe 41 is installed between the air pipe nozzle and the air inlet pipe 4, and a first control valve 40 is installed between the air inlet pipe 4 and the connecting pipe 41. The first control valve 40 is used to control the on-off of the gas path between the air inlet pipe 4 and the connecting pipe 41;

[0075] A button 30 is installed on the cleaning gun 3, and the button 30 is signal-connected to the first control valve 40.

[0076] Actually, according to the actual situation, a on-off mechanism can also be directly provided in the gun body 31 to realize the on-off of the gas path. In this embodiment, the button 30 on the cleaning gun 3 is used to control the action of the first control valve 40, control the on-off of the gas path between the air inlet pipe 4 and the main barrel 32, and further control the blowing of the cleaning brush 2. The structure is simple, the installation is convenient, and the practicability is relatively strong.

[0077] There are two cleaning guns 3.

[0078] In fact, according to the actual situation, the cleaning gun 3 can also be set to one. In this embodiment, by setting the cleaning gun 3 to two, it is possible to alternately use the two cleaning guns 3 at both ends of the condenser 1 to reciprocally blow the cleaning brush 2 in the copper tube 10, so that the cleaning brush 2 reciprocally moves in the copper tube 10, improving the cleaning efficiency.

[0079] The buttons 30 of the two cleaning guns 3 are both signal-connected to the same first control valve 40;

[0080] The first control valve 40 is a three-position electromagnetic reversing valve;

[0081] When the button 30 of the first cleaning gun 3 is pressed and the three-position electromagnetic reversing valve is in the first position, the main barrel 32 of the first cleaning gun 3 is in communication with the air inlet pipe 4, and the main barrel 32 of the second cleaning gun 3 is in communication with the outside atmosphere;

[0082] When the button 30 of the second cleaning gun 3 is pressed and the three-position electromagnetic reversing valve is in the second position, the main barrel 32 of the first cleaning gun 3 is in communication with the outside atmosphere, and the main barrel 32 of the second cleaning gun 3 is in communication with the air inlet pipe 4;

[0083] When the buttons 30 of the two cleaning guns 3 are not pressed and the three-position electromagnetic reversing valve is in the third position, the air inlet pipe 4 is disconnected from the main barrels 32 of the two cleaning guns 3.

[0084] In fact, according to the actual situation, two independent first control valves 40 can also be selected and controlled separately by the two cleaning guns 3. In this embodiment, by jointly controlling the same first control valve 40 with the two buttons 30, the number of first control valves 40 used can be reduced, manufacturing costs can be saved, and the practicability is relatively strong.

[0085] The first control valve 40 is a three-position four-way electromagnetic reversing valve or a three-position five-way electromagnetic reversing valve.

[0086] A secondary barrel 33 and a water pipe nozzle that are interconnected are further installed on the gun body 31;

[0087] The main barrel 32 is arranged in parallel with the secondary barrel 33;

[0088] The distance dimension between the main barrel 32 and the secondary barrel 33 is the same as the distance dimension between two adjacent copper tubes 10;

[0089] The water pipe nozzle on one of the gun bodies 31 is connected to an inlet pipe 5 that is in communication with a pressurized water source;

[0090] The water pipe nozzle on the other gun body 31 is connected to an outlet pipe 52.

[0091] In fact, according to actual conditions, another water pipe can be provided to rinse the copper tube 10 that has been cleaned. In this embodiment, by providing the auxiliary gun barrel 33, the water inlet pipe 5 and the water outlet pipe 52, the auxiliary gun barrel 33 can be used to rinse the copper tube 10 that has been cleaned after the main gun barrel 32 uses the cleaning brush 2. While performing the secondary rinse, the main gun barrel 32 can be aligned with the next copper tube 10 to be cleaned synchronously, thereby improving the cleaning efficiency.

[0092] At the same time, the auxiliary gun barrel 33 of the cleaning gun 3 connected with the water outlet pipe 52 is used to receive the sewage after flushing the copper tube 10, thereby avoiding the splashing of sewage, and having strong practicality.

[0093] A second control valve 51 is installed on the water inlet pipe 5, and the second control valve 51 is used to control the on-off of the water path in the water inlet pipe 5;

[0094] The button 30 on the gun body 31 connected to the water inlet pipe 5 is connected to the second control valve 51 by signal;

[0095] The pressurized water source is the tap water pipe.

[0096] In fact, according to actual conditions, the pressurized water source can be set as a water pump, and a control component can be set separately. In this embodiment, the second control valve 51, the button 30 on the gun body 31 connected to the water inlet pipe 5 and the tap water pipe cooperate with each other. When the button 30 on the gun body 31 connected to the water inlet pipe 5 is pressed, the air path between the air inlet pipe 4 and the connecting pipe 41 is connected, and the water path in the water inlet pipe 5 is controlled to be on and off. In conjunction with the pressurized water source of the tap water pipe, the copper tube 10 is flushed without the need for additional control, and the operation is convenient and the practicability is strong.

[0097] The second control valve 51 includes a time relay.

[0098] In fact, according to actual conditions, the second control valve 51 can be set to automatically reset after the corresponding button 30 is released. This embodiment controls the flushing time of the pressurized water source through a time relay, and no additional control is required, which is very practical.

[0099] The length of the main barrel 32 is greater than the length of the cleaning brush 2 .

[0100] In fact, the length of the main barrel 32 can also be set to be smaller than the cleaning brush 2 according to actual conditions. When in use, the cleaning brush 2 is first inserted into the copper tube 10. This embodiment limits the length of the main barrel 32, so that when in use, the cleaning brush 2 can be directly inserted into the main barrel 32, and then the main barrel 32 can be aligned with the copper tube 10, which is more convenient to use.

[0101] An annular groove is provided on the inner wall of the free end of the main barrel 32 , and the diameter of the annular groove matches the outer diameter of the copper tube 10 .

[0102] Through the arrangement of the annular groove, the free end of the main barrel 32 can be directly sleeved on the copper tube 10, completing the radial positioning between the main barrel 32 and the copper tube 10, which is more convenient to use and has strong practicability.

[0103] The inner diameter dimension of the secondary barrel 33 matches the outer diameter dimension of the copper tube 10.

[0104] Actually, according to the actual situation, the outer diameter dimension of the secondary barrel 33 can also be set to match the inner diameter dimension of the copper tube 10. In this embodiment, by limiting the inner diameter dimension of the secondary barrel 33, the free end of the secondary barrel 33 can be directly sleeved on the copper tube 10, completing the radial positioning between the secondary barrel 33 and the copper tube 10, which is more convenient to use and has strong practicability.

[0105] Both the main barrel 32 and the secondary barrel 33 are detachably connected to the gun body 31.

[0106] Actually, according to the actual situation, the main barrel 32 and the secondary barrel 33 can also be directly fixedly connected to the gun body 31. In this embodiment, through the detachable connection of the main barrel 32, the secondary barrel 33 and the gun body 31, corresponding main barrels 32 and secondary barrels 33 with different pipe diameters can be installed according to the different inner diameters / outer diameters of the copper tubes 10 in different condensers 1, and then cleaning brushes 2 with different outer diameters can be configured, improving the adaptation range of the cleaning device and having strong practicability.

[0107] There are two brush bodies 21, and the two brush bodies 21 are coaxially connected, and the sealing mechanism 22 is located between the two brush bodies 21.

[0108] Actually, according to the actual situation, only one brush body 21 can be set, and the sealing mechanism 22 can be set at the end of the brush body 21. In this embodiment, by setting brush bodies 21 at both ends of the sealing mechanism 22, no matter which end the cleaning brush 2 is inserted into the copper tube 10, it is the brush body 21 that contacts the copper tube 10 first relative to the sealing mechanism 22, that is, the brush body 21 brushes the copper tube 10 first and then contacts the sealing mechanism 22, reducing the possibility that the sealing mechanism 22 is stuck in the copper tube 10 due to the scale in the copper tube 10 not being cleaned, and having strong practicability.

[0109] A threaded blind hole 211 is opened on one of the brush bodies 21, and a threaded post 212 is fixedly arranged on the other brush body 21;

[0110] The threaded post 212 is screwed into the threaded blind hole 211;

[0111] The sealing mechanism 22 is a sealing ring.

[0112] In fact, according to the actual situation, the two brush bodies 21 can also be integrally formed directly, and then a sealing sleeve is sleeved in the middle thereof as the sealing mechanism 22. In this embodiment, the two brush bodies 21 are fixedly connected by screwing the threaded posts 212 into the threaded blind holes 211, and the sealing ring serving as the sealing mechanism 22 is fixed between the two brush bodies 21. The structure is simple, and it is convenient to replace the sealing ring after long-term use, with strong practicability.

[0113] Hexagonal heads 213 are provided on the outer walls of the inner ends of the brush bodies 21.

[0114] Through the arrangement of the hexagonal heads 213, when screwing the two brush bodies 21 together, a hexagonal wrench can be directly used for operation, making disassembly and assembly more convenient.

[0115] Hard pads 220 are provided on both sides of the sealing ring, and the hard pads 220 are sleeved on the threaded posts 212;

[0116] The outer diameter dimension of the hard pad 220 is smaller than the outer diameter dimension of the sealing ring.

[0117] The sealing ring is protected by the hard pads 220, avoiding damage to the sealing ring due to the relative movement of the two brush bodies 21 when screwing the two brush bodies 21 together, with strong practicability.

[0118] A number of hard bristles 210 are provided on the brush body 21.

[0119] In fact, according to the actual situation, a sponge can also be directly selected as the brush body 21 to complete the cleaning of the inner wall of the copper tube 10. In this embodiment, the hard bristles 210 replace the brush body 21 to contact the inner wall of the copper tube 10, thereby completing the cleaning of the inner wall of the copper tube 10. The structure is simple and the cleaning effect is good; among them, the hard bristles 210 can be copper wires or nylon wires.

[0120] In this embodiment, during use, two operators each hold a cleaning gun 3 and stand at both ends of the condenser 1 respectively, and then insert the cleaning brush 2 into the main barrel 32 of one of the cleaning guns 3;

[0121] After that, the main barrels 32 of the two cleaning guns 3 are aligned with the same copper tube 10 of the condenser 1;

[0122] Press the button 30 on the cleaning gun 3 loaded with the cleaning brush 2, so that the connecting pipe 41 corresponding to this cleaning gun 3 is communicated with the air inlet pipe 4 (this embodiment refers to the first row position, specifically, it can be Figure 7 the left row position in), and then the air source blows the sealing mechanism 22 of the cleaning brush 2, so that the cleaning brush 2 moves in the copper tube 10, and the inner wall of the copper tube 10 is scrubbed by the hard bristles 210 on the brush body 21 until the cleaning brush 2 moves into the main barrel 32 of the other cleaning gun 3;

[0123] During this process, the main barrel 32 of the second cleaning gun 3 is in a state of being connected to the outside atmosphere, which can ensure smooth air flow;

[0124] Then release the pressing of the button 30 of the first cleaning gun 3. At this time, the air inlet pipe 4 and the main barrels 32 of both cleaning guns 3 are in a disconnected state (in this embodiment, it is referred to as the third row position, specifically, it can be Figure 7 the middle row position in);

[0125] Press the button 30 of the second cleaning gun 3 again, so that the connecting pipe 41 corresponding to the second cleaning gun 3 is connected to the air inlet pipe 4 (in this embodiment, it is referred to as the second row position, specifically, it can be Figure 7 the right row position in), so that the cleaning brush 2 is blown from the main barrel 32 of the second cleaning gun 3 back into the main barrel 32 of the first cleaning gun 3;

[0126] Repeat multiple times to complete the cleaning of the corresponding copper pipe 10;

[0127] After completing the cleaning of the first copper pipe 10, align the main barrels 32 of both cleaning guns 3 with the next copper pipe 10, and then the new copper pipe 10 can be cleaned;

[0128] When aligning the main barrel 32 with the second copper pipe 10, the secondary barrels 33 on both cleaning guns 3 are also aligned with the previous copper pipe 10 that has been cleaned by the cleaning brush 2. In this way, when the second copper pipe 10 is being cleaned by the cleaning brush 2, the second control valve 51 controls the water circuit in the water inlet pipe 5 to be connected, so that the water from the tap water pipe enters the copper pipe 10 through the secondary barrel 33, flushes the copper pipe 10, and then enters the water outlet pipe 52 through the secondary barrel 33 of the other cleaning gun 3;

[0129] It should be noted that if the scale in the copper pipe 10 is serious, it needs to be soaked with a descaling agent first. After soaking, open the end covers on both sides of the condenser, and then use the cleaning device to clean it.

[0130] The above has introduced in detail a condenser cleaning device provided by the present invention. The description of the specific embodiments is only used to help understand the method and its core idea of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can still be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
