Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, specifically a dirt cleaning device for the condenser tubes of a water-cooled unit. Background Technology

[0002] Some large mechanical equipment are equipped with water-cooled refrigeration systems. Water-cooled refrigeration systems are mainly used to cool the equipment. They usually consist of four basic parts: compressor, condenser, expansion valve, and evaporator. The four main components are connected in a certain order by copper pipes to form a closed system, which is filled with a certain amount of refrigerant.

[0003] After a water-cooled chiller has been running for a period of time, water droplets will condense on the inner walls of the copper tubes of the evaporator and condenser. These water droplets will form scale and verdigris on the inner walls of the copper tubes over a long period of time. When scale and verdigris form on the tube walls, they will affect the cooling efficiency of the water-cooled chiller. Therefore, it is necessary to clean the scale in a timely manner. However, chemical cleaning substances are highly corrosive. During the cleaning process, the copper tube walls will also be corroded by the chemical substances and gradually become thinner, affecting the service life of the water-cooled chiller. Manual cleaning, on the other hand, requires manual disassembly of the equipment, which greatly increases labor costs. Therefore, there is a need for a device that can easily clean the scale on the inner walls of the condenser tubes of the water-cooled chiller. Summary of the Invention

[0009] Preferably, the sewage discharge assembly further includes a bracket, a connecting seat, a filter screen, and a threaded plug. Two brackets are fixedly connected to the arc-shaped pipe, two connecting seats are threadedly connected to two sewage discharge pipes, two filter screens are fixedly connected to two connecting seats respectively, and two threaded plugs are threadedly connected to two connecting seats respectively.

[0010] Preferably, the opening and closing assembly includes a housing, a connecting pipe, a water-blocking pad, a rotating seat, and a water passage hole. The two housings are respectively fixedly connected to both ends of the condenser pipe, the two connecting pipes are respectively fixedly connected to the two housings, the four water-blocking pads are respectively fixedly connected to the inner walls of the two housings, the two rotating seats are respectively rotatably connected between the four water-blocking pads, and the two water passage holes are respectively opened on the two rotating seats.

[0011] Preferably, the opening and closing assembly further includes a turntable, a connecting block, and a fixing block. The two turntables are rotatably connected to the two housings respectively, the two turntables are fixedly connected to the two rotating seats respectively, the two connecting blocks are fixedly connected to the two turntables respectively, and the four fixing blocks are fixedly connected to the two housings respectively.

[0012] Preferably, the limiting assembly includes a rotating shaft, a stop bar, a slide groove, a connecting piece, and a spring. The two rotating shafts are rotatably connected to the inner wall of the condenser tube. The two stop bars are respectively fixedly connected to the two rotating shafts. The two slide grooves are formed on the inner wall of the condenser tube. The two connecting pieces are respectively fixedly connected to the two rotating shafts and are slidably connected to the inside of the two slide grooves. The two springs are respectively fixedly connected between the inner walls of the two connecting pieces and the two slide grooves.

[0013] This invention provides an improved device for cleaning scale from the condenser tubes of a water-cooled unit, which has the following improvements and advantages compared to the prior art:

[0014] Firstly, in this invention, when the condenser is in normal use to cool the equipment, water flows inside. When the condenser stops working, water droplets remain on its inner wall, forming scale. To clean this scale, the two turntables on the two housings are rotated. The rotation of the turntables causes two rotating seats to rotate within the housing. The originally open water holes are now blocked by two water-blocking pads, thus sealing both ends of the condenser. At this point, an external water source can be connected to the inlet pipe. External water enters the arc-shaped tube through the inlet pipe. The water inside the arc-shaped tube is injected into the entire arc-shaped tube through the second through hole on the baffle. The inner diameter of the arc-shaped tube is the same as that of the condenser tube, while the outer diameter of the rubber sleeve outside the hollow ball is slightly larger than the inner diameter of the arc-shaped tube. Therefore, the water inside the arc-shaped tube will push the hollow ball under water pressure and then enter the condenser tube. Due to the guidance of the guide plate, the hollow ball will pass through the middle section of the entire condenser tube, and during the movement, the scale on the inner wall of the condenser tube will be removed by the friction between the outer rubber sleeve and the inner wall of the condenser tube.

[0015] Secondly, in this invention, during the process of cleaning the inner wall of the condenser tube with the hollow ball, the hollow ball will enter the other end of the arc-shaped tube from the other end of the condenser tube along with the sewage. At this time, the threaded plug is removed by spiraling, and the sewage in the arc-shaped tube will be discharged. The dirt will accumulate on the filter screen. After the sewage is drained, the connecting seat can be removed to clean the dirt on the filter screen. When the sewage is drained, the hollow ball is no longer subject to the buoyancy of the water and will slowly roll down to the bottom of the arc-shaped tube, abutting against the sliding rod, causing the sliding rod to slide. When the sliding rod slides, the connecting rod and rubber pad on it move, bringing it closer to the hollow ball. The second through hole is no longer blocked by the rubber pad, while the other second through hole is blocked by the rubber pad. When it is necessary to clean the inner wall of the condenser tube again, water is injected through the water inlet pipe. The water will enter the arc-shaped tube through the other second through hole, so that the hollow ball enters the condenser tube from the arc-shaped tube. Therefore, each time the inner wall of the condenser tube is cleaned, the hollow ball will move from one end to the other end of the arc-shaped tube, and at the same time change the starting direction of the water flow in the arc-shaped tube for the next cleaning. After the cleaning is completed, the turntable is rotated again to connect the two ends of the condenser tube, so that the condenser tube can be used normally. Attached Figure Description

[0026] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] This invention provides an improved device for cleaning scale from the condenser tubes of a water-cooled unit. The technical solution of this invention is as follows:

[0028] like Figures 1-7As shown, a dirt cleaning device for the condenser tube of a water-cooled unit includes a condenser tube 1, an arc-shaped tube 2 fixedly connected to the condenser tube 1, a hollow ball 3 inside the arc-shaped tube 2, a rubber sleeve 4 fixedly connected to the hollow ball 3, a plurality of grooves 5 on the rubber sleeve 4, a flushing assembly 6 inside the arc-shaped tube 2, the flushing assembly 6 including a water inlet pipe 61 fixedly connected to the bottom of the arc-shaped tube 2, a drain assembly 7 on the arc-shaped tube 2, the drain assembly 7 including a drain pipe 71, two drain pipes 71 fixedly connected to the arc-shaped tube 2, opening and closing assemblies 8 at both ends of the condenser tube 1, and a limiting assembly 9 inside the condenser tube 1.

[0029] Furthermore, the flushing assembly 6 also includes baffles 62, first through holes 63, and slide rods 64. The two baffles 62 are fixedly connected to the inner wall of the arc-shaped tube 2, and the two first through holes 63 are respectively opened on the two baffles 62. The slide rods 64 are slidably connected to the inside of the two first through holes 63. When the hollow ball 3 cleans the inner wall of the condenser tube 1, it will move from one end to the other end inside the arc-shaped tube 2. When the hollow ball 3 moves to the other end, it will press against the slide rods 64, causing the slide rods 64 to move under the gravity of the hollow ball 3.

[0030] Furthermore, the flushing assembly 6 also includes a second through hole 65, a connecting rod 66, and a rubber pad 67. The two second through holes 65 are respectively opened on the two baffles 62, the two connecting rods 66 are fixedly connected to the sliding rod 64, and the two rubber pads 67 are respectively fixedly connected to the two connecting rods 66. The movement of the hollow ball 3 will cause the sliding rod 64 to move, thereby causing the connecting rod 66 and the rubber pad 67 to move, so as to ensure that after water enters the water inlet pipe 61, the water will always flow to the end where the hollow ball 3 is located in the arc-shaped pipe 2 first. The rubber pad 67 can stop the water flow by pressing against the second through hole 65. When the second through hole 65 is not blocked by the rubber pad 67, water can flow from the second through hole 65 into the entire interior of the arc-shaped pipe 2 after entering the water inlet pipe 61.

[0031] Furthermore, the flushing assembly 6 also includes guide plates 68 and third through holes 69. The two guide plates 68 are fixedly connected to the inner wall of the condenser tube 1, and multiple third through holes 69 are respectively opened on the two guide plates 68. The guide plates 68 are used to guide the hollow ball 3 so that the hollow ball 3 will move in the correct direction when it enters the condenser tube 1 from the arc tube 2.

[0032] Furthermore, the sewage discharge assembly 7 also includes a bracket 72, a connecting seat 73, a filter screen 74, and a threaded plug 75. The two brackets 72 are fixedly connected to the arc-shaped pipe 2, the two connecting seats 73 are threadedly connected to the two sewage discharge pipes 71, the two filter screens 74 are fixedly connected to the two connecting seats 73 respectively, and the two threaded plugs 75 are threadedly connected to the two connecting seats 73 respectively. By screwing the threaded plugs 75 off, the sewage in the arc-shaped pipe 2 will be discharged, and the dirt will accumulate on the filter screen 74. After the sewage is discharged, the connecting seat 73 can be removed to clean the dirt on the filter screen 74.

[0033] Furthermore, the opening and closing assembly 8 includes a housing 81, a connecting pipe 82, a water-blocking pad 83, a rotating seat 84, and a water passage hole 85. The two housings 81 are respectively fixedly connected to the two ends of the condenser pipe 1, the two connecting pipes 82 are respectively fixedly connected to the two housings 81, the four water-blocking pads 83 are respectively fixedly connected to the inner walls of the two housings 81, the two rotating seats 84 are respectively rotatably connected between the four water-blocking pads 83, and the two water passage holes 85 are respectively opened on the two rotating seats 84.

[0034] Furthermore, the opening and closing assembly 8 also includes a turntable 86, a connecting block 87, and a fixing block 88. The two turntables 86 are rotatably connected to the two housings 81 respectively, and the two turntables 86 are fixedly connected to the two rotating seats 84 respectively. The two connecting blocks 87 are fixedly connected to the two turntables 86 respectively, and the four fixing blocks 88 are fixedly connected to the two housings 81 respectively. When the turntables 86 on the two housings 81 are twisted, the two turntables 86 will drive the two rotating seats 84 to rotate inside the housings 81. The water passage holes 85 that were originally open at both ends will be blocked by the two water-blocking pads 83 after rotation. Therefore, the two ends of the condenser tube 1 will be closed by the two housings 81 respectively. At this time, the water inlet pipe 61 can be connected to an external water source so that external water can enter the arc-shaped tube 2 through the water inlet pipe 61.

[0035] Furthermore, the limiting assembly 9 includes a rotating shaft 91, a stop bar 92, a slide groove 93, a connecting piece 94, and a spring 95. Two rotating shafts 91 are rotatably connected to the inner wall of the condenser tube 1. Two stop bars 92 are respectively fixedly connected to the two rotating shafts 91. Two slide grooves 93 are formed on the inner wall of the condenser tube 1. Two connecting pieces 94 are respectively fixedly connected to the two rotating shafts 91, and the two connecting pieces 94 are respectively slidably connected inside the two slide grooves 93. Two springs 95 are respectively fixedly connected to the two connecting pieces 94 and the two slide grooves 93. Between the inner walls of tube 3, the hollow ball 3 will move from one end of the arc-shaped tube 2 to the condenser tube 1 under the action of water pressure, and then move to the other end of the condenser tube 1, and then to the other end of the arc-shaped tube 2. During this process, the hollow ball 3 will pass through two baffles 92. After passing through the baffles 92, the hollow ball 3 can no longer move in the opposite direction. Therefore, when the hollow ball 3 moves to the baffles 92, it will be subjected to the elastic force of the spring 95 below the baffles 92. Therefore, the hollow ball 3 will not get stuck at the connection between the condenser tube 1 and the arc-shaped tube 2.

[0036] Working principle: When the condenser tube 1 is in normal use, it is used to cool the equipment. Water flows inside it. When the condenser tube 1 stops working, water droplets remain on its inner wall, which then form scale. When it is necessary to clean this scale, the turntables 86 on the two housings 81 can be turned first. After the two turntables 86 are turned, the two rotating seats 84 rotate inside the housing 81. The water holes 85, which were originally open at both ends, are blocked by the two water-blocking pads 83 after rotation. Therefore, the two ends of the condenser tube 1 are closed by the two housings 81. At this time, the water inlet pipe 61 can be connected to an external water source to allow external water to flow. Water enters the arc-shaped tube 2 through the inlet pipe 61. The water then flows through the second through-hole 65 on the baffle 62, filling the entire arc-shaped tube 2. The inner diameter of the arc-shaped tube 2 is the same as that of the condenser tube 1, while the outer diameter of the rubber sleeve 4 surrounding the hollow sphere 3 is slightly larger than the inner diameter of the arc-shaped tube 2. Therefore, the water in the arc-shaped tube 2 causes the hollow sphere 3 to be pushed by water pressure, thus entering the condenser tube 1. Guided by the guide plate 68, the hollow sphere 3 passes through the middle section of the condenser tube 1, and during its movement, the friction between the outer rubber sleeve 4 and the inner wall of the condenser tube 1 removes scale from the inner wall of the condenser tube 1. Afterwards, the hollow ball 3 and the sewage enter from the other end of the condenser tube 1 to the other end of the arc-shaped tube 2. At this time, the threaded plug 75 is removed by screwing, and the sewage in the arc-shaped tube 2 will be discharged. The dirt will accumulate on the filter screen 74. After the sewage is drained, the connecting seat 73 can be removed to clean the dirt on the filter screen 74. When the sewage is drained, the hollow ball 3 is no longer subject to the buoyancy of the water and will slowly roll down to the bottom of the arc-shaped tube 2, abutting against the slide rod 64, causing the slide rod 64 to slide. When the slide rod 64 slides, the connecting rod 66 and the rubber pad 67 on it move, so that the second through hole 65 near the hollow ball 3 is no longer subject to the buoyancy of the water. With the rubber pad 67 blocking the other second through hole 65, when the inner wall of the condenser tube 1 needs to be cleaned again, water is injected through the water inlet pipe 61, and the water will enter the arc-shaped tube 2 through the other second through hole 65, so that the hollow ball 3 enters the condenser tube 1 from the arc-shaped tube 2. Therefore, each time the inner wall of the condenser tube 1 is cleaned, the hollow ball 3 will move from one end to the other end of the arc-shaped tube 2, and at the same time change the starting direction of the water flow in the arc-shaped tube 2. After the cleaning is completed, the turntable 86 is rotated again to connect the boxes 81 at both ends of the condenser tube 1, so that the condenser tube 1 can be used normally.
