Description

Technical Field

[0001] The utility model belongs to the technical field of tube ice evaporators, and specifically relates to a novel tube ice evaporator. Background Art

[0002] With the continuous development of refrigeration technology, the tube ice evaporator, as an important refrigeration equipment, is widely used in many fields such as food, medicine, and chemical industry. Its working principle is as follows: first, when preparing tube ice, the water inside the water tank enters the inside through the water inlet of the heat exchange ice-making pipe, and then the refrigerant liquid enters the inside of the evaporator body through the refrigerant liquid inlet. The refrigerant liquid outside exchanges heat with the water in the heat exchange ice-making pipe. Since the temperature of the refrigerant is much lower than the temperature of the water, the water begins to cool down rapidly on the inner wall of the steel pipe and gradually freezes. The freezing process starts from the inner wall of the heat exchange ice-making pipe and proceeds to the center of the heat exchange ice-making pipe until the tube ice is formed. When the ice layer reaches a predetermined thickness, the system will detect and automatically stop the water flow to prevent the ice layer from being too thick. The heater set inside the heat exchange ice-making pipe is used to heat the tube ice and separate it from the inner wall of the heat exchange ice-making pipe. Then, the tube ice is discharged from the outlet of the heat exchange ice-making pipe by gravity. The tube ice evaporator realizes the rapid freezing of water through the heat exchange between the refrigerant and water, thereby meeting various refrigeration needs.

[0003] In the prior art, during the long-term operation of the evaporator, various impurities such as microorganisms, oil, dust, and corroded metal particles will be generated due to the effects of refrigerant, water source, and environmental factors. These impurities will not only affect the flow and heat transfer performance of the refrigerant, but also adhere to the surface of the heat exchange ice-making pipe, reducing the heat exchange efficiency, thereby affecting the overall performance of the evaporator.

[0004] Secondly, in order to improve the heat exchange effect of the heat exchange ice-making pipe, some special structures such as threads or stepped grooves are often set on the heat exchange ice-making pipe in the prior art. Although these structures can increase the heat exchange area and improve the heat exchange efficiency, they are also more likely to cause impurities to remain and accumulate. In the long run, these impurities will further affect the heat exchange performance of the heat exchange ice-making pipe, and may even cause pipe blockage and shorten the service life of the evaporator.

[0005] To this end, we proposed a new tube ice evaporator, which uses a de-impurity brush to remove impurities on the heat exchange and ice-making tubes, thereby increasing the service life of the evaporator and improving the heat exchange effect. Utility Model Content

[0006] The utility model aims to provide a novel tube ice evaporator, which removes impurities on the heat exchange ice-making tube by means of a de-impurity brush, thereby increasing the service life of the evaporator and improving the heat exchange effect.

[0007] The technical solutions adopted in this utility are as follows:

[0008] A novel tube ice evaporator comprises an evaporator body and a water tank arranged on the top of the evaporator body, the evaporator body is provided with a refrigerant liquid inlet and a refrigerant gas outlet, a plurality of heat exchange ice-making tubes are arranged inside the evaporator body, the water inlet of each heat exchange ice-making tube is connected to the water tank, and a plurality of heat exchange ice-making tubes are provided with impurity removal components;

[0009] The impurity removal component includes an impurity removal sleeve mounted on the plurality of heat exchange and ice-making pipes, a floating connecting plate is provided between every two impurity removal sleeves for connection, an impurity removal brush is provided inside each impurity removal sleeve, a sliding component is provided inside the evaporator body, a connecting block is provided on the sliding component, and one side of the connecting block is connected to one of the impurity removal sleeves.

[0010] Furthermore, the heat exchange and ice-making pipe is matched with the impurity removal sleeve and the floating connecting plate.

[0011] Furthermore, the heat exchange ice-making pipe is provided with threads.

[0012] Furthermore, the sliding assembly includes a slide groove opened on the inner wall of the evaporator body, a fixed shaft is arranged inside the slide groove, a sliding block is sleeved on the fixed shaft, and one side of the sliding block is connected to the connecting block.

[0013] Furthermore, the sliding block matches the sliding groove.

[0014] Furthermore, an anti-corrosion layer is provided on the impurity removal sleeve and the impurity removal brush.

[0015] The technical effects achieved by this utility model are:

[0016] First, when preparing tube ice, the water inside the water tank enters the interior through the water inlet of the heat exchange ice-making pipe, and then the refrigerant liquid enters the interior of the evaporator body through the refrigerant liquid inlet. The outside of the refrigerant liquid exchanges heat with the water in the heat exchange ice-making pipe. Since the temperature of the refrigerant is much lower than the temperature of the water, the water begins to cool down rapidly on the inner wall of the steel pipe and gradually freezes. The freezing process starts from the inner wall of the heat exchange ice-making pipe and proceeds to the center of the heat exchange ice-making pipe until tube ice is formed. When the ice layer reaches a predetermined thickness, the system will detect and automatically stop the entry of water flow to prevent the ice layer from being too thick. The tube ice is heated by a heater arranged inside the heat exchange ice-making pipe to separate the tube ice from the inner wall of the heat exchange ice-making pipe, and then the tube ice is discharged from the outlet of the heat exchange ice-making pipe by gravity. When the refrigerant liquid is heat exchanged, impurities (such as microorganisms, oil, dust and corroded metal particles) will be generated due to the evaporator itself and the refrigerant. At the same time, in the prior art, special structures (such as threads or stepped grooves) are arranged on the heat exchange ice-making pipe to enhance the heat exchange effect, but these structures are more likely to cause impurities to remain, resulting in a poor heat exchange effect of the heat exchange ice-making pipe. For this reason, when the coolant liquid enters from the bottom of the evaporator, the buoyancy generated will cause the floating connecting plate to drive the impurity removal sleeve to move upward through the sliding assembly. During the upward movement, the impurities on the heat exchange ice-making pipe are removed by the impurity removal brush, thereby increasing the service life of the evaporator and improving the heat exchange effect.

[0024] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0025] like Figure 1-5 As shown, the technical solution adopted by the utility model is specifically as follows: a new type of tube ice evaporator, comprising an evaporator body 1 and a water tank 2 arranged on the top of the evaporator body 1, the evaporator body 1 is provided with a refrigerant liquid inlet 3 and a refrigerant gas outlet 4, a plurality of heat exchange ice-making tubes 5 are arranged inside the evaporator body 1, the water inlet of each heat exchange ice-making tube 5 is connected to the water tank 2, and a plurality of heat exchange ice-making tubes 5 are provided with impurity removal components;

[0026] The impurity removal component includes an impurity removal sleeve 6 sleeved on multiple heat exchange and ice-making pipes 5, a floating connecting plate 7 is provided between every two impurity removal sleeves 6 for connection, and an impurity removal brush 8 is provided inside each impurity removal sleeve 6. A sliding component is provided inside the evaporator body 1, and a connecting block 9 is provided on the sliding component. One side of the connecting block 9 is connected to one of the impurity removal sleeves 6.

[0027] Its working principle is as follows: first, when preparing tube ice, the water inside the water tank 2 enters the inside through the water inlet of the heat exchange ice-making pipe 5, and then the refrigerant liquid enters the inside of the evaporator body 1 through the refrigerant liquid inlet 3. The outside of the refrigerant liquid exchanges heat with the water in the heat exchange ice-making pipe 5. Since the temperature of the refrigerant is much lower than the temperature of the water, the water begins to cool down rapidly on the inner wall of the steel pipe and gradually freezes. The freezing process starts from the inner wall of the heat exchange ice-making pipe 5 and proceeds to the center of the heat exchange ice-making pipe 5 until tube ice is formed. When the ice layer reaches a predetermined thickness, the system will detect and automatically stop the entry of water flow to prevent the ice layer from being too thick. The heater set inside the heat exchange ice-making pipe 5 is used to heat the tube ice and separate it from the inner wall of the heat exchange ice-making pipe 5. Then, the tube ice is discharged from the outlet of the heat exchange ice-making pipe 5 by gravity. When the refrigerant liquid undergoes heat exchange, impurities (such as microorganisms, oil, and dust) will be generated due to the evaporator itself and the refrigerant. Dust and corroded metal particles), and in the prior art, special structures (such as threads or stepped grooves) are arranged on the heat exchange ice-making pipe 5 to enhance the heat exchange effect, but these structures are more likely to cause impurities to remain, resulting in poor heat exchange effect of the heat exchange ice-making pipe 5. For this reason, when the coolant liquid enters from the bottom of the evaporator, the buoyancy generated will cause the floating connecting plate 7 to drive the impurity removal sleeve 6 to move upward through the sliding assembly. During the upward movement, the impurities on the heat exchange ice-making pipe 5 are removed by the impurity removal brush 8, thereby increasing the service life of the evaporator and improving the heat exchange effect.

[0028] Among them, the reasons for the generation of impurities inside the evaporator are:

[0029] 1. Quality of refrigerant: The refrigerant may contain impurities such as moisture, oil, dust, etc. These impurities may accumulate inside the evaporator.

[0030] 2. Cleanliness of the system: If the evaporator is not adequately cleaned during installation or maintenance, impurities may remain on the pipes, heat exchanger surfaces, etc.

[0031] 3. Corrosion and wear: The metal parts inside the evaporator may be corroded and worn, producing impurities such as metal particles.

[0032] 4. Microbial growth: In some cases, microorganisms such as bacteria and mold may grow inside the evaporator, and their metabolites may also become impurities.

[0033] 5. Due to the special design of the heat exchange ice-making pipe 5 (such as threads or stepped grooves), the heat exchange effect is enhanced, but these structures are more likely to cause impurities to remain.

[0034] Therefore, the utility model can remove impurities on the surface of the heat exchange ice-making pipe 5 by providing an impurity removal component.

[0035] At the same time, the floating connecting plate 7, the impurity removal sleeve 6 and the connecting block 9 are all made of plastic, so that they can be light in weight and the generated adhesion can make them float.

[0036] The heat exchange ice-making pipe 5 is matched with the impurity removal sleeve 6 , the floating connecting plate 7 and the connecting block 9 . Matching here means distribution matching, that is, the floating connecting plate 7 drives the impurity removal sleeve 6 and the connecting block 9 to move back and forth on the heat exchange ice-making pipe 5 .

[0037] After the evaporator is finished working, the refrigerant is discharged, the adhesion disappears, and the floating connecting plate 7 drives the impurity removal sleeve 6 and the connecting plate to return to their original positions on the heat exchange and ice making pipe 5, thereby further cleaning the impurities. The removed impurities fall to the bottom of the evaporator body 1 and are removed by manpower.

[0038] The heat exchange ice-making tube 5 is provided with threads, and the refrigerant liquid can fully contact the heat exchange ice-making tube 5 through the threads, thereby improving the heat exchange effect.

[0039] The sliding assembly includes a slide groove 10 opened on the inner wall of the evaporator body 1 , a fixed shaft 11 is arranged inside the slide groove 10 , a sliding block 12 is sleeved on the fixed shaft 11 , and one side of the sliding block 12 is connected to the connecting block 9 .

[0040] When the adhesion force is generated, the connecting block 9 moves upward, thereby driving the sliding block 12 to move on the fixed shaft 11 inside the sliding groove 10, so that shaking does not occur, thereby improving stability.

[0041] The slider 12 matches the slide groove 10 , and matching here means that the slider 12 can slide smoothly inside the slide groove 10 without getting stuck.

[0042] The impurity removal sleeve 6 and the impurity removal brush 8 are provided with an anti-corrosion layer, and the service life of the impurity removal sleeve 6 and the impurity removal brush 8 can be increased by the anti-corrosion layer.

[0043] It should be noted that: due to the provision of the sliding component, the impurity removal sleeve 6 operates stably. During maintenance, an inspection window is generally provided on the evaporator body 1, through which the impurity removal component can be cleaned or repaired.

[0044] The working principle of the utility model is as follows: first, when preparing tube ice, the water inside the water tank 2 enters the inside through the water inlet of the heat exchange ice-making tube 5, and then the refrigerant liquid enters the inside of the evaporator body 1 through the refrigerant liquid inlet 3. The outside of the refrigerant liquid exchanges heat with the water inside the heat exchange ice-making tube 5. Since the temperature of the refrigerant is much lower than the temperature of the water, the water begins to cool down rapidly on the inner wall of the steel pipe and gradually freezes. The freezing process starts from the inner wall of the heat exchange ice-making tube 5 and proceeds to the center of the heat exchange ice-making tube 5 until tube ice is formed. When the ice layer reaches a predetermined thickness, the system will detect and automatically stop the entry of water flow to prevent the ice layer from being too thick. The heater set inside the heat exchange ice-making tube 5 is used to heat the tube ice to separate the inner wall of the heat exchange ice-making tube 5, and then the tube ice is discharged from the outlet of the heat exchange ice-making tube 5 by gravity. When the refrigerant liquid is undergoing heat exchange, impurities (such as microorganisms, oil, ash, etc.) will be generated due to the evaporator itself and the refrigerant. Dust and corroded metal particles), and in the prior art, special structures (such as threads or stepped grooves) are arranged on the heat exchange ice-making pipe 5 to enhance the heat exchange effect, but these structures are more likely to cause impurities to remain, resulting in poor heat exchange effect of the heat exchange ice-making pipe 5. For this reason, when the coolant liquid enters from the bottom of the evaporator, the buoyancy generated will cause the floating connecting plate 7 to drive the impurity removal sleeve 6 to move upward through the sliding assembly. During the upward movement, the impurities on the heat exchange ice-making pipe 5 are removed by the impurity removal brush 8, thereby increasing the service life of the evaporator and improving the heat exchange effect.

[0045] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
