Description

Technical Field

[0001] The invention relates to the field of antifreezing devices for drain pipes, and in particular to an antifreezing device for drain pipes used in cold storages. Background Art

[0002] The cooling exhaust pipe is an air natural convection heat exchange evaporator. Except for the operation without the negative pressure fan, the liquid supply operation procedure is basically the same as the cold negative pressure fan. When the cooling exhaust pipe is running, first open the return air valve and then slowly open the liquid supply valve to supply liquid to the cooling exhaust pipe. The cold storage exhaust pipe (coil) has good thermal conductivity: aluminum alloy has excellent thermal conductivity, the temperature difference between the evaporation temperature of the refrigerant and the outer surface of the aluminum row will decrease, the evaporation temperature will increase, the energy efficiency ratio of the compressor will increase, and the energy consumption will decrease; the structure is special.

[0003] The cold storage pipes are located inside the cold storage, and there are many products stored inside the cold storage. Therefore, there is still a certain amount of moisture inside the empty space. Since the air around the cold storage pipes is lower, the water vapor in the air can easily condense on the surface of the cold storage pipes. As time goes by, the surface of the pipes will freeze, which will seriously affect the freezing effect of the pipes. Summary of the invention

[0004] The main purpose of the present invention is to provide a cold storage pipe anti-icing device, which can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a pipe anti-icing device for a cold storage, comprising a plurality of straight pipes and curved pipes, the straight pipes are connected by curved pipes, both the straight pipes and the curved pipes are made of aluminum alloy and have good heat conduction capability, the straight pipes are arranged longitudinally, and the curved pipes are staggered at the end positions of two adjacent straight pipes, so that the straight pipes and the curved pipes form a plurality of S-shaped groups, a plurality of supporting links are installed on the surface of the straight pipes, an arc-shaped clamping plate is fixedly installed on one end of the supporting links, the cross-section of the arc-shaped clamping plate is an arc-shaped, a mounting frame is clamped inside the arc-shaped clamping plate, hygroscopic cotton is installed inside the mounting frame, and the surface of the hygroscopic cotton is in contact with the interior of the cold storage.

[0006] A plurality of supporting ring plates are installed on the surface of the straight pipe, and ventilation grooves are opened on the surface of the supporting ring plates. An isolation straight pipe and an isolation bent pipe are sleeved on the surface of the straight pipe, and the isolation bent pipe is sleeved on the surface of the bent pipe. Ventilation grooves are opened on the surfaces of the isolation straight pipe and the isolation bent pipe, and dry gas is passed between the isolation straight pipe and the straight pipe.

[0007] A negative pressure fan is installed inside the cold storage, one end of the negative pressure fan is connected to a drying fan, one end of the drying fan is installed with a connecting pipe, and the other end of the negative pressure fan is connected to between the isolation straight pipe and the straight exhaust pipe.

[0008] The surface of the isolation straight pipe is provided with multiple circles of thread groove groups, and the multiple circles of thread groove groups are linearly arrayed on the surface of the isolation straight pipe. The support connecting rod is a threaded rod and is threadedly installed inside the thread groove. The support connecting rod is installed between two rows of ventilation grooves.

[0009] Two internal threaded pipes are arranged on the surface of the isolation elbow pipe. The bend row pipe is installed inside the isolation elbow pipe. Both ends of the isolation elbow pipe extend into the internal threaded pipes, and the isolation straight pipe is installed inside the internal threaded pipes.

[0010] The mounting frame includes multiple mounting cylinders. Multiple connecting plates are installed between the multiple mounting cylinders, and the multiple connecting plates are annularly arrayed on the surface of the mounting cylinders. The mounting cylinders are stuck inside the arc-shaped clamping plates.

[0011] The mounting cylinder includes two semi-circular shells. Threaded semi-grooves are arranged on the surfaces of the semi-circular shells at both ends of the mounting frame. The two threaded semi-grooves are combined into a complete threaded circular groove. Threaded sleeves are installed at both ends of the mounting frame. The moisture-absorbing cotton is installed between the two semi-circular shells. Since there are certain gaps between the connecting plates, it can ensure that the moisture-absorbing cotton absorbs moisture. When the moisture-absorbing cotton needs to be replaced, only the threaded sleeves at both ends need to be rotated and removed.

[0012] Arc-shaped pressing plates are arranged inside the semi-circular shells. The shape of the arc-shaped pressing plates is arc-shaped. The distance between two adjacent arc-shaped pressing plates is less than the diameter of the moisture-absorbing cotton, and the diameter of the moisture-absorbing cotton is greater than the diameter of the mounting cylinder.

[0013] The distance between the two sides of the ventilation groove close to the straight discharge pipe is less than the distance between the two sides close to the mounting cylinder. The ventilation groove is located between two adjacent arc-shaped pressing plates.

[0014] One end of the connecting pipe is communicated with the inside of the cold storage. Since the connecting pipe is connected to the inside of the cold storage, it can ensure that the entering air has a certain temperature. At this time, the gas entering the cold storage will be about the same as the temperature inside the cold storage. Therefore, heat transfer can be reduced, and the refrigeration effects of the straight discharge pipe and the bend row pipe can be ensured.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the present invention, by providing a mounting bracket, a straight exhaust pipe, a curved exhaust pipe, and a moisture-absorbing cotton, when the straight exhaust pipe and the curved exhaust pipe are in use, the surrounding temperature will be reduced. Since the air around the straight exhaust pipe and the curved exhaust pipe has a certain humidity, water vapor will condense between the straight exhaust pipe and the curved exhaust pipe. However, due to the moisture-absorbing cotton provided on the surface, the surrounding water vapor will be absorbed by the moisture-absorbing cotton, causing the moisture-absorbing cotton to freeze. After freezing to a certain extent, the mounting bracket can be removed from the surface of the arc-shaped clamping plate, and then a new mounting bracket can be replaced, which can largely prevent the surfaces of the straight exhaust pipe and the curved exhaust pipe from freezing, and the structure is very simple.

[0017] 2. In the present invention, by providing a ventilation groove, a ventilation slot, an isolation elbow pipe, and an isolation straight pipe, the gas passes through the ventilation groove and enters between each isolation elbow pipe and the curved exhaust pipe. The dry gas can also prevent a certain amount of water vapor on the surfaces of the straight exhaust pipe and the curved exhaust pipe, avoiding the surfaces of the straight exhaust pipe and the curved exhaust pipe from icing. Moreover, the dry gas can flow out from the position of the ventilation slot, blowing away the air containing water vapor on the surfaces of the isolation straight pipe and the isolation elbow pipe, reducing the water vapor absorbed by the moisture-absorbing cotton, increasing the service life of the moisture-absorbing cotton, reducing the replacement efficiency, and being more convenient to use.

[0018] 3. In the present invention, by providing a negative pressure fan, a connecting pipe, and a drying fan, starting the negative pressure fan, the negative pressure fan can suck the gas from one end and flow it to the other end. When the gas passes through the inside of the drying fan, the water vapor contained inside can be absorbed. One end of the connecting pipe is connected to the inside of the cold storage. Since the connecting pipe is connected to the inside of the cold storage, it can ensure that the entering air has a certain temperature. At this time, the gas entering the inside of the cold storage will be about the same temperature as the inside of the cold storage, so the heat transfer can be reduced, ensuring the refrigeration effect of the straight exhaust pipe and the curved exhaust pipe.

[0019] 4. In the present invention, by providing a mounting cylinder, a connecting plate, and an arc-shaped clamping plate, the mounting cylinder and the connecting plate are of an integrated structure, which can improve the connection stability between the mounting cylinder and the connecting plate. The mounting cylinder is stuck inside the arc-shaped clamping plate. The diameter of the mounting cylinder is the same as the diameter of the arc-shaped clamping plate. The notch diameter of the arc-shaped clamping plate is smaller than the diameter of the mounting cylinder. However, the arc-shaped clamping plate is made of plastic and has a certain elasticity. Therefore, simply pressing the mounting cylinder can make it stuck inside the arc-shaped clamping plate, and the operation is very simple.

[0020] 5. In the present invention, by providing a moisture-absorbing cotton, a semi-circular shell, and a threaded sleeve, the moisture-absorbing cotton is installed between two semi-circular shells. Since there are certain gaps between the connecting plates, the moisture-absorbing cotton can be ensured to absorb moisture. When it is necessary to replace the moisture-absorbing cotton, only the threaded sleeves at both ends need to be rotated and removed, and the two semi-circular shells can be easily separated. At this time, the moisture-absorbing cotton can be taken away and replaced with a new one. The replaced moisture-absorbing cotton can be thawed and dried, and then reused, thereby reducing the usage cost. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] like Figure 1-8 As shown, in order to achieve the above purpose, the technical solution adopted by the present invention is: a cold storage pipe anti-icing device, comprising a plurality of straight pipes 1 and curved pipes 2, the straight pipes 1 and the curved pipes 2 are both made of aluminum alloy and have good heat conduction capacity, the straight pipes 1 are arranged longitudinally, and the curved pipes 2 are arranged longitudinally. The straight pipes 1 are staggered and installed at the end positions of two adjacent straight pipes 1, so that the straight pipes 1 and the curved pipes 2 form multiple groups of S shapes. The straight pipes 1 are connected by the curved pipes 2, and the straight pipes 1 and the curved pipes 2 are connected by welding. A plurality of supporting connecting rods 3 are installed on the surface of the straight pipes 1 in a linear and annular array on the surface of the straight pipes 1. An arc-shaped clamping plate 4 is fixedly installed on one end of the supporting connecting rod 3, so that the arc-shaped clamping plate 4 is a certain distance away from the straight pipes 1. The cross-section of the arc-shaped clamping plate 4 is an excellent arc shape, and the arc-shaped clamping plate 4 has certain elastic properties. A mounting frame 5 is clamped inside the arc-shaped clamping plate 4. Since the arc-shaped clamping plate 4 is an excellent arc shape, the diameter of the mounting frame 5 is adapted to the diameter of the arc-shaped clamping plate 4, and the notch of the arc-shaped clamping plate 4 is smaller than the diameter of the mounting frame 5, so the mounting frame 5 is installed on the arc-shaped clamping plate 4. When it is inside the cold storage, it will not fall off due to gravity, but the mounting frame 5 can be removed manually, and the operation is very convenient. The mounting frame 5 is installed with hygroscopic cotton 6, which has strong hygroscopic performance and can absorb moisture from the surrounding air. The surface of the hygroscopic cotton 6 is in contact with the interior of the cold storage.

[0032] During use, the mounting frame 5 is a strip structure, so it is installed using the arc-shaped clamping plate 4 in the same row. The mounting frame 5 is annularly installed on the surface of the straight-row pipe 1, and some distance is set between each mounting frame 5. When the straight-row pipe 1 and the curved-row pipe 2 are in use, the surrounding temperature will be lowered. Since the air around the straight-row pipe 1 and the curved-row pipe 2 has a certain humidity, water vapor will condense between the straight-row pipe 1 and the curved-row pipe 2. However, since the surface is provided with hygroscopic cotton 6, the surrounding water vapor will be absorbed by the hygroscopic cotton 6, so the hygroscopic cotton 6 will freeze. When it is frozen to a certain extent, the mounting frame 5 can be removed from the surface of the arc-shaped clamping plate 4, and then replaced with a new mounting frame 5. The operation is very convenient, and can largely avoid the freezing of the surface of the straight-row pipe 1 and the curved-row pipe 2, and the structure is very simple.

[0033] A plurality of support ring plates 7 are mounted on the surface of the straight exhaust pipe 1. The support ring plates 7 are sleeved on the surface of the straight exhaust pipe 1 in a linear array. Ventilation grooves 8 are formed on the surface of the support ring plate 7, and the number of the ventilation grooves 8 is set to be plural. An isolation straight pipe 9 and an isolation elbow 10 are sleeved on the surface of the support ring plate 7. When installing, the curved exhaust pipe 2 needs to be placed inside the isolation elbow 10 first, and then the straight exhaust pipe 1 is welded. Finally, the isolation straight pipe 9 is installed. The isolation straight pipe 9 is sleeved on the surface of the straight exhaust pipe 1, and the isolation elbow 10 is sleeved on the surface of the curved exhaust pipe 2. Ventilation slots 11 are formed on the surfaces of the isolation straight pipe 9 and the isolation elbow 10, and dry gas is passed between the isolation straight pipe 9 and the straight exhaust pipe 1.

[0034] When the dry gas enters the interiors of the isolation straight pipe 9 and the straight exhaust pipe 1, the gas will pass through the ventilation grooves 8 and enter between each isolation elbow 10 and the curved exhaust pipe 2. The dry gas can also prevent a certain amount of water vapor from appearing on the surfaces of the straight exhaust pipe 1 and the curved exhaust pipe 2, avoiding ice formation on the surfaces of the straight exhaust pipe 1 and the curved exhaust pipe 2. Moreover, the dry gas can flow out from the positions of the ventilation slots 11, blowing away the air containing water vapor on the surfaces of the isolation straight pipe 9 and the isolation elbow 10, reducing the water vapor absorbed by the moisture-absorbing cotton 6, increasing the service life of the moisture-absorbing cotton 6, reducing the replacement efficiency, and being more convenient to use.

[0035] A negative pressure fan 12 is installed inside the cold storage. One end of the negative pressure fan 12 is connected to a drying fan 13. One end of the drying fan 13 is provided with a connecting pipe 14. The other end of the negative pressure fan 12 communicates and enters between the isolation straight pipe 9 and the straight exhaust pipe 1. When in use, the negative pressure fan 12 is started first. The negative pressure fan 12 can suck gas from one end and flow it to the other end. When the gas passes through the interior of the drying fan 13, the water vapor contained inside can be absorbed.

[0036] A plurality of groups of multi-turn thread grooves 15 are formed on the surface of the isolation straight pipe 9. The plurality of groups of multi-turn thread grooves 15 are linearly arrayed on the surface of the isolation straight pipe 9. The support connecting rod 3 is a threaded rod and is threadedly installed inside the thread groove 15. The support connecting rod 3 is installed between two rows of ventilation slots 11, and does not affect the gas flow effect of the ventilation slots 11. When the surfaces of the support connecting rod 3 and the arc-shaped clamping plate 4 are damaged, the support connecting rod 3 can be directly rotated and removed from the interior of the thread groove 15, and the installation is also very convenient.

[0037] The surface of the isolation elbow 10 is provided with two internal threaded pipes 16. The inner diameter of the isolation elbow 10 is greater than the overall radius of the curved pipe row 2, ensuring that the curved pipe row 2 is completely located inside the isolation elbow 10. The curved pipe row 2 is installed inside the isolation elbow 10. The two ends of the isolation elbow 10 extend into the internal threaded pipes 16. The isolation straight pipe 9 is installed inside the internal threaded pipes 16, which is convenient for the installation of the isolation straight pipe 9 and can make the connection between the isolation straight pipe 9 and the isolation elbow 10 tighter, preventing the outflow of dry gas.

[0038] The mounting bracket 5 includes a plurality of mounting cylinders 17. A plurality of connecting plates 18 are installed between the plurality of mounting cylinders 17. The plurality of connecting plates 18 are annularly arranged on the surface of the mounting cylinders 17. The mounting cylinders 17 and the connecting plates 18 are of an integrated structure, which can improve the connection stability between the mounting cylinders 17 and the connecting plates 18. The mounting cylinders 17 are stuck inside the arc-shaped clamping plates 4. The diameter of the mounting cylinders 17 is the same as the diameter of the arc-shaped clamping plates 4. The diameter of the notch of the arc-shaped clamping plates 4 is smaller than the diameter of the mounting cylinders 17. However, the arc-shaped clamping plates 4 are made of plastic and have a certain elasticity. Therefore, directly pressing the mounting cylinders 17 can make them stuck inside the arc-shaped clamping plates 4, and the operation is very simple.

[0039] The mounting cylinder 17 includes two semi-circular shell halves 19. Both of the two semi-circular shell halves 19 are semi-circular. The two semi-circular shell halves 19 form a circle. Threaded semi-grooves 20 are provided on the surfaces of the semi-circular shell halves 19 at both ends of the mounting bracket 5. The two threaded semi-grooves 20 are combined into a complete threaded circular groove. Threaded sleeves 21 are installed at both ends of the mounting bracket 5. The moisture-absorbing cotton 6 is installed between the two semi-circular shell halves 19. Since there are certain gaps between the connecting plates 18, it can ensure that the moisture-absorbing cotton 6 absorbs moisture. When the moisture-absorbing cotton 6 needs to be replaced, only need to rotate and remove the threaded sleeves 21 at both ends, and the two semi-circular shell halves 19 can be easily separated. At this time, the moisture-absorbing cotton 6 can be taken away and replaced with a new one. The replaced moisture-absorbing cotton 6 can be thawed and dried, and then reused, so as to reduce the use cost.

[0040] Arc-shaped pressing plates 22 are provided inside the semi-circular shell halves 19. The shape of the arc-shaped pressing plates 22 is arc-shaped. The distance between two adjacent arc-shaped pressing plates 22 is smaller than the diameter of the moisture-absorbing cotton 6. The diameter of the moisture-absorbing cotton 6 is greater than the diameter of the mounting cylinder 17. The two arc-shaped pressing plates 22 can press the moisture-absorbing cotton 6, improving the friction between the moisture-absorbing cotton 6 and the arc-shaped pressing plates 22 and preventing the moisture-absorbing cotton 6 from falling off from inside the mounting cylinder 17.

[0041] The distance between the two sides of the ventilation groove 11 close to the straight exhaust pipe 1 is smaller than the distance between the two sides close to the installation cylinder 17. The gas between the straight exhaust pipe 1 and the isolation straight pipe 9 can overflow from the inside of the ventilation groove 11. Therefore, when the dry gas passes through the inside of the ventilation groove 11, the diffusion area of the dry gas will be increased, and the air containing water vapor around the isolation straight pipe 9 can be blown away to a greater extent. The ventilation groove 11 is located between two adjacent arc-shaped clamping plates 4.

[0042] One end of the connecting pipe 14 is communicated with the inside of the cold storage. Since the connecting pipe 14 is connected to the inside of the cold storage, it can ensure that the entering air has a certain temperature. At this time, the gas entering the cold storage will be about the same temperature as the inside of the cold storage, so the heat transfer can be reduced, and the refrigeration effect of the straight exhaust pipe 1 and the curved exhaust pipe 2 can be ensured.

[0043] It should be noted that the present invention is a pipe anti-icing device for a cold storage. When in use, first install the isolation straight pipe 9 and the isolation elbow 10 on the surfaces of the straight exhaust pipe 1 and the curved exhaust pipe 2. The isolation straight pipe 9 rotates inside the internal thread pipe 16, and the support connecting rod 3 is rotatably installed inside the thread groove 15. At the same time, the moisture-absorbing cotton 6 is clamped inside the semi-circular shell 19, and the threaded sleeves 21 at both ends are installed. Then, the installation cylinder 17 is clamped inside the arc-shaped clamping plate 4, and the mounting frame 5 is annularly installed on the surface of the straight exhaust pipe 1. There is a certain distance between each mounting frame 5. When the straight exhaust pipe 1 and the curved exhaust pipe 2 are in use, the surrounding temperature will be reduced. Since the air around the straight exhaust pipe 1 and the curved exhaust pipe 2 has a certain humidity, water vapor will condense between the straight exhaust pipe 1 and the curved exhaust pipe 2. However, due to the moisture-absorbing cotton 6 provided on the surface, the surrounding water vapor will be absorbed by the moisture-absorbing cotton 6, so the moisture-absorbing cotton 6 will freeze. When the dry gas enters the inside of the isolation straight pipe 9 and the straight exhaust pipe 1, the gas will pass through the ventilation groove 8 and enter between each isolation elbow 10 and the curved exhaust pipe 2. The dry gas can also prevent a certain amount of water vapor from forming on the surfaces of the straight exhaust pipe 1 and the curved exhaust pipe 2, avoiding icing on the surfaces of the straight exhaust pipe 1 and the curved exhaust pipe 2. Moreover, the dry gas can flow out from the position of the ventilation groove 11, blowing away the air containing water vapor on the surfaces of the isolation straight pipe 9 and the isolation elbow 10, reducing the water vapor absorbed by the moisture-absorbing cotton 6, increasing the service time of the moisture-absorbing cotton 6, reducing the replacement efficiency, and being more convenient to use. When frozen to a certain extent, the mounting frame 5 can be removed from the surface of the arc-shaped clamping plate 4, then the two threaded sleeves 21 are removed, and then the moisture-absorbing cotton 6 is removed. The operation is very convenient, and it can largely avoid icing on the surfaces of the straight exhaust pipe 1 and the curved exhaust pipe 2, and the structure is very simple.
