Abstract

The present invention discloses a freezing and transportation device for fish ball processing, which relates to the technical field of cold chain transport vehicles and includes: a carriage, on the outer side of which a heat insulation component is fixed; an outer shell and an inner shell, the outer shell is fixed on the outer side wall of the carriage, the inner shell is fixed on the inner side wall of the carriage, and a refrigeration system is arranged in the outer shell; a partition board, which is fixed on the inner wall of the inner shell, and a fixed cover is fixed on the side wall of the partition board. The present invention can seal the gap between the first copper tube and the second copper tube through a control component so that the refrigerant only flows in the second copper tube, in order to avoid a large amount of heat being transferred to the refrigerant during the defrosting process of the heat exchange component. After the gap between the first copper tube and the second copper tube is sealed, the refrigerant between the first copper tube and the second copper tube is pumped out through a negative pressure component, and a highly vacuum state is created between the first copper tube and the second copper tube, further reducing the heat transfer to the refrigerant.

Description

Technical Field

[0001] The present invention relates to the technical field of cold chain transport vehicles, and in particular to a freezing and transporting device for fish ball processing. Background Art

[0002] A cold chain transport vehicle is an enclosed van used to transport frozen or fresh goods, and is a special refrigerated transport vehicle equipped with a refrigeration device and a heat-insulating compartment. It is commonly used to transport frozen foods. During the fish ball processing, the transportation of its ingredients or finished products requires the use of a cold chain transport vehicle.

[0003] In the prior art, during the operation of most cold chain transports, since the temperature inside the compartment is usually below zero, the evaporator of the cold chain transport vehicle freezes (in most cases, ice will form on the surface of the fins of the evaporator). Ice affects heat transfer. Therefore, in order to reduce the energy consumption of the refrigeration system, de-icing work needs to be carried out.

[0004] Currently, the de-icing principle of the evaporator of most cold chain transport vehicles is to use high-temperature refrigerant to flow through the evaporator, that is, to heat the evaporator so that the ice and frost on the surface of the evaporator melt. In this process, the coordinated work of the control system and various valves is required, resulting in a relatively high cost of the refrigeration system. In addition, some directly use an electric heating de-icing system. This kind of de-icing work requires the refrigeration system to stop working. Otherwise, it will cause an increase in the energy consumption of the heating system. After the refrigeration system is turned off, the refrigerant remaining inside the evaporator will also be heated up by the electric heating system, which will also cause an increase in energy consumption during the subsequent operation of the refrigeration system.

[0092] As shown in the following combination with Figures 1 to 17 An embodiment of the present invention provides a freezing and transporting device for fish ball processing, including:

[0093] A carriage 101, with a heat insulation component fixed on the outer side of the carriage 101;

[0094] An outer housing 102 and an inner housing 104. The outer housing 102 is fixed on the outer side wall of the carriage 101, and the inner housing 104 is fixed on the inner side wall of the carriage 101. A refrigeration system is provided inside the outer housing 102;

[0095] A partition plate 401, fixed on the inner wall of the inner housing 104, and a fixed cover 402 is fixed on the side wall of the partition plate 401;

[0096] A heat exchange component, fixed inside the fixed cover 402;

[0097] A first copper tube 801, fixed inside the fixed cover 402, and the first copper tube 801 is connected to the heat exchange component;

[0098] A second copper tube 802 is arranged inside the first copper tube 801. A plurality of support plates 803 are arranged on the outer side wall of the second copper tube 802, and the plurality of support plates 803 are all fixed to the inner wall of the first copper tube 801;

[0099] A control assembly is fixed inside the inner housing 104. The control assembly is communicated with both ends of the first copper tube 801 and the second copper tube 802, and the control assembly is communicated with the refrigeration system;

[0100] A negative pressure assembly penetrates through the inner wall of the first copper tube 801, and the negative pressure assembly is used to extract the gas between the first copper tube 801 and the second copper tube 802;

[0101] A drainage assembly penetrates through the fixed cover 402, and the drainage assembly is communicated with the heat insulation assembly.

[0102] When the refrigeration system works, the refrigerant flows in the first copper tube 801 and the second copper tube 802, that is, the refrigerant can evaporate in the first copper tube 801 and the second copper tube 802 to reduce the temperature of the heat exchange assembly, and then realize the refrigeration in the carriage 101. After the control assembly works, the refrigerant cannot enter the gap between the first copper tube 801 and the second copper tube 802, and only flows in the second copper tube 802. At the same time, with the cooperation of the negative pressure assembly, the space between the first copper tube 801 and the second copper tube 802 is in a highly vacuum state, so when deicing the heat exchange assembly, the heat transfer to the refrigerant is reduced, so as to reduce the energy consumption required for heating, and at the same time, the energy consumption of the refrigeration system is also reduced.

[0103] Furthermore, the control assembly includes:

[0104] A seat body 701 is fixed inside the inner housing 104. Two chambers are provided in the seat body 701, and both ends of the first copper tube 801 penetrate through the two chambers respectively;

[0105] A heat insulation shell 105 is fixed to the outer housing 102 and the inner housing 104;

[0106] Two connecting pipes 110 are respectively communicated with the two chambers, and both of the two connecting pipes 110 are communicated with the refrigeration system. Both of the two connecting pipes 110 are located inside the heat insulation shell 105;

[0107] Two control units are respectively arranged in the two chambers, and both of the two control units are communicated with the negative pressure assembly.

[0108] Furthermore, the control unit includes:

[0109] A sleeve 702 is fixed to the bottom of the seat body 701, and the top of the sleeve 702 penetrates through the inner wall of the chamber;

[0110] The third piston 706 is slidably arranged within the sleeve 702;

[0111] The sleeve rod 703 is fixed to the top of the third piston 706;

[0112] The connecting frame 704 is fixed to the top of the sleeve rod 703;

[0113] The plug 705 is fixed to the top of the connecting frame 704. The plug 705 is of an annular structure and is used to seal the gap between the first copper tube 801 and the second copper tube 802;

[0114] The gas transmission pipe 603 communicates with the sleeve 702.

[0115] When the negative pressure assembly operates, gas is injected into the sleeve 702 through the gas transmission pipe 603, and the third piston 706 within the sleeve 702 is pushed to move upward. Through the action of the sleeve rod 703 and the connecting frame 704, the plug 705 is driven to abut against the first copper tube 801 and the second copper tube 802, thereby sealing the gap between the first copper tube 801 and the second copper tube 802. Since the plug 705 is of an annular structure and does not affect the flow of the refrigerant within the second copper tube 802, the refrigerant can maintain normal operation at this time, and only the rotational speed of the compressor in the refrigeration system needs to be reduced.

[0116] Furthermore, the negative pressure assembly includes:

[0117] The cylinder body 601 is fixed within the inner housing 104;

[0118] The hydraulic push rod 602 and the adjustment pipe 607 are both fixed to one end of the cylinder body 601. Moreover, the telescopic end of the hydraulic push rod 602 penetrates through the inner wall of the cylinder body 601. The adjustment pipe 607 communicates with the cylinder body 601, and the gas transmission pipe 603 is disposed through the side wall of the cylinder body 601 near the gas transmission pipe 603;

[0119] The second piston 606 is slidably arranged within the cylinder body 601, and the second piston 606 is fixed to the telescopic end of the hydraulic push rod 602;

[0120] The second solenoid valve 604 is disposed through the other end of the cylinder body 601;

[0121] The negative pressure pipe 605 communicates with the second solenoid valve 604 and penetrates through the inner wall of the first copper tube 801.

[0122] After the gap between the first copper tube 801 and the second copper tube 802 is sealed by the plug 705, the switch of the second solenoid valve 604 is turned on, and the second piston 606 is continuously driven to move by the hydraulic push rod 602. During this process, the side of the second piston 606 in the cylinder 601 is in a highly vacuum state. Under the action of the air pressure difference, the refrigerant between the first copper tube 801 and the second copper tube 802 enters the cylinder 601 through the negative pressure tube 605 and the second solenoid valve 604, so as to reduce the gas density between the first copper tube 801 and the second copper tube 802. As the second piston 606 continues to move, the vacuum degree between the first copper tube 801 and the second copper tube 802 also gradually increases.

[0123] Further, it also includes:

[0124] A support plate 608, and the support plate 608 is fixed inside the adjustment tube 607;

[0132] A guiding pipe 503, one end of the guiding pipe 503 is communicated with the first solenoid valve 502, and the other end of the guiding pipe 503 penetrates through the inner wall of the bottom of the fixed cover 402;

[0133] An annular plate 505, the annular plate 505 is fixed inside the collecting pipe 501, and a plurality of through holes 507 are provided on the side wall of the annular plate 505 near the annular plate 505;

[0134] A first spring 506, and the first spring 506 is fixed on the inner wall of the collecting pipe 501;

[0135] The first piston 504 is slidably arranged in the collecting pipe 501, and the first piston 504 and the first spring 506 are fixed.

[0136] When the air pressure inside the inner housing 104 rises, the gas inside the inner housing 104 enters the collecting pipe 501 through the through hole 507 on one side of the collecting pipe 501, pushing the first piston 504 to move. During the movement of the first piston 504, the water in the collecting pipe 501 is pushed to the drain pipe 305, and the water is then input into one of the water tanks 302 through the drain pipe 305 for storage.

[0137] Furthermore, the heat exchange component includes:

[0138] The fin 404 is fixed inside the fixed cover 402, and the first copper pipe 801 passes through the fin 404;

[0139] The heating plate 403 is fixed on the top of the fin 404.

[0140] Furthermore, it also includes:

[0141] The installation box 106 is fixed at the bottom of the inner housing 104. An air pump is arranged inside the installation box 106. The output end of the air pump penetrates the inner wall of the bottom of the inner housing 104, and an air outlet is provided on one side of the inner housing 104;

[0142] The sealing plate 107 is rotatably arranged at the air outlet of the inner housing 104;

[0143] Two electric push rods 108 are respectively rotatably arranged on two side walls of the inner housing 104. A connecting rod 109 is rotatably arranged at the telescopic end of each electric push rod 108, and the connecting rod 109 is rotatably connected to the sealing plate 107.

[0144] After the deicing operation, turn on the switch of the electric push rod 108. The electric push rod 108 contracts to drive the sealing plate 107 to rotate through the connecting rod 109, and then seals the air outlet of the inner housing 104 through the sealing plate 107. Then turn on the switch of the air pump to increase the air pressure inside the inner housing 104.

[0145] Furthermore, the heat insulation component includes:

[0146] The heat insulation shell 201 is fixed on the outside of the carriage 101;

[0147] The water curtain 203 is fixed inside the heat insulation shell 201. A box door 103 is hinged on one side of the carriage 101;

[0148] A plurality of air inlet holes 202 are all opened on the side wall of the heat insulation shell 201 away from the box door 103.

[0149] Further, it also includes:

[0150] Two water tanks 302, both of which are fixed on the side wall of the carriage 101;

[0151] A drain pipe 305, one end of the drain pipe 305 is provided with a valve, and the valve is communicated with one of the water tanks 302. The other end of the drain pipe 305 is communicated with the collection pipe 501, and a water injection pipe is arranged on the other water tank 302;

[0152] A water pump box 301, which is fixed on the side wall of the carriage 101, and a liquid pump is arranged inside the water pump box 301;

[0153] A first pipe body 303, which is communicated with the input end of the liquid pump, and the first pipe body 303 is communicated with the two water tanks 302;

A communication seat 306 is fixed on the side wall of the heat insulation shell 201, and the communication seat 306 is communicated with the second pipe body 304. The communication seat 306 penetrates through the side wall of the heat insulation shell 201, and the water curtain 203 penetrates through the communication seat 306.

[0155] During transportation, if the weather is sunny and the sun shines on the heat insulation shell 201, resulting in an increase in the temperature inside the carriage 101, turn on the switch of the water pump. When the water pump works, it pumps out the water inside the two water tanks 302 through the first pipe body 303, and inputs it into the communication seat 306 through the second pipe body 304, so that the water curtain 203 is in a wet state. During the movement of the cold chain transport vehicle, the outside air enters the heat insulation shell 201 through the air inlet hole 202 and flows through the surface of the water curtain 203. Since the water curtain 203 is infiltrated, when the air flows through the surface of the water curtain 203, the water on the water curtain 203 evaporates and absorbs heat, thereby reducing the temperature inside the heat insulation shell 201, so as to keep the temperature outside the carriage 101 within a lower range and reduce the temperature rise inside the carriage 101 caused by direct sunlight.

[0156] The specific working method is: when in use, load the fish ball products into the carriage 101, and add a certain amount of water to one of the water tanks 302 through the water injection pipe;

[0157] During transportation, the air in the carriage 101 enters the inner housing 104 through the operation of the air pump. The air is guided by the partition plate 401 and then flows through the fins 404 and is output through the air outlet, so as to realize the air circulation in the carriage 101. The refrigerant flows in the first copper pipe 801 through the operation of the refrigeration system, reducing the temperature of the fins 404, and then reducing the ambient temperature inside the carriage 101 to ensure that the fish balls remain in a low temperature state during transportation;

[0158] During the cold chain transportation process, the gas temperature in the carriage 101 is relatively low, and as the working time increases, ice will inevitably form on the fins 404. If icing occurs during transportation, due to the low thermal conductivity efficiency of ice and frost, the temperature inside the carriage 101 will rise. In order to ensure the temperature inside the carriage 101 and also to reduce energy consumption, de-icing work needs to be carried out during the driving of the cold chain transport vehicle;

[0159] When carrying out de-icing work, first turn on the switch of the hydraulic push rod 602. The hydraulic push rod 602 contracts and drives the second piston 606 to move at the same time. During the movement of the second piston 606, the gas on one side of the second piston 606 in the cylinder body 601 is injected into the sleeve 702 through the air pipe 603, and the third piston 706 in the sleeve 702 is pushed to move upward. Through the action of the sleeve rod 703 and the connecting frame 704, the plug 705 is driven to abut against the first copper pipe 801 and the second copper pipe 802, so that the gap between the first copper pipe 801 and the second copper pipe 802 is sealed. Since the plug 705 is of an annular structure and does not affect the flow of the refrigerant in the second copper pipe 802, the refrigerant can maintain normal operation at this time, and only the rotational speed of the compressor in the refrigeration system needs to be reduced;

[0160] After the plug 705 seals the gap between the first copper pipe 801 and the second copper pipe 802, turn on the switch of the second solenoid valve 604, and continuously drive the second piston 606 to move through the hydraulic push rod 602. During this process, the other side of the second piston 606 in the cylinder body 601 is in a highly vacuum state. Under the action of the air pressure difference, the refrigerant between the first copper pipe 801 and the second copper pipe 802 enters the cylinder body 601 through the negative pressure pipe 605 and the second solenoid valve 604 to reduce the gas density between the first copper pipe 801 and the second copper pipe 802. As the second piston 606 continues to move, the vacuum degree between the first copper pipe 801 and the second copper pipe 802 also gradually increases;

[0161] Subsequently, turn off the air pump to stop the gas flow in the carriage 101, and then turn on the switch of the heating plate 403. When the heating plate 403 works, it heats the fins 404 to melt the ice and frost on the surface of the fins 404, and the melted ice and frost fall to the bottom of the fixed cover 402. Then turn on the switch of the first solenoid valve 502, and the water at the bottom of the fixed cover 402 enters the collection pipe 501 through the guiding pipe 503 and the first solenoid valve 502 to complete the de-icing work;

[0162] After the de-icing operation, turn on the switch of the electric push rod 108. The electric push rod 108 contracts and drives the sealing plate 107 to rotate through the connecting rod 109. Then, the air outlet of the inner housing 104 is sealed through the sealing plate 107. Next, after closing the first solenoid valve 502, turn on the switch of the air pump, so that the air pressure inside the inner housing 104 rises. The gas inside the inner housing 104 enters the collection pipe 501 through the through hole 507 on one side of the collection pipe 501, pushing the first piston 504 to move. During the movement of the first piston 504, the water in the collection pipe 501 is pushed to the drain pipe 305, and the water is then input into one of the water tanks 302 through the drain pipe 305 for storage;

[0163] After the de-icing operation, control the hydraulic push rod 602 to reset, so that the refrigerant can flow in the gap between the first copper pipe 801 and the second copper pipe 802 to ensure the refrigeration effect. At the same time, the refrigerant in the cylinder body 601 is re-injected into the first copper pipe 801 to participate in the refrigeration cycle;

[0164] During the movement of the second piston 606, the excess gas in the cylinder body 601 between the second piston 606 and the regulating pipe 607 will enter the regulating pipe 607. When the air pressure in the regulating pipe 607 is too high, it pushes the first baffle 609 to move, so that the excess gas in the regulating pipe 607 is output through the gap between the regulating pipe 607 and the first baffle 609. When the air pressure in the regulating pipe 607 is too low, the external air pressure pushes the second baffle 610 and the first baffle 609 to separate, and the external gas can enter the regulating pipe 607, thereby reducing the resistance during the movement of the second piston 606;

[0165] During transportation, if the weather is sunny and the sunlight shines on the heat insulation shell 201, causing the temperature inside the carriage 101 to rise, turn on the switch of the water pump. When the water pump works, it pumps out the water inside the two water tanks 302 through the first pipe body 303 and inputs it into the connecting seat 306 through the second pipe body 304, so that the water curtain 203 is in a wet state. During the movement of the cold chain transport vehicle, the external gas enters the heat insulation shell 201 through the air inlet hole 202 and flows through the surface of the water curtain 203. Since the water curtain 203 is wetted, the water in the water curtain 203 evaporates and absorbs heat when the gas flows through the surface of the water curtain 203, thereby reducing the temperature inside the heat insulation shell 201, so as to keep the temperature outside the carriage 101 within a lower range and reduce the temperature rise inside the carriage 101 caused by direct sunlight.

[0166] It should be noted that the operations of the power components such as the air pump, liquid pump, hydraulic push rod 602, electric push rod 108, etc. recorded in the present invention are all controlled by an automated system. The working states of the automated control electrical appliances are extremely mature prior arts and are not the innovative points of the present invention, so no further description is given;

[0167] In addition, a temperature sensor and a humidity sensor are provided inside the heat insulation shell 201. When the temperature inside the heat insulation shell 201 is relatively high, the control system turns on the water pump to inject water into the heat insulation shell 201. However, when the humidity inside the heat insulation shell 201 is too high, the control system turns off the water pump to avoid wasting water resources and also to prevent excessive bacterial reproduction caused by the high humidity in the heat insulation shell 201;

[0168] Finally, the refrigeration system is also composed of existing technologies such as a compressor and a condenser, which will not be elaborated here. It should be particularly noted that the expansion valve should be installed close to the seat body 701 to prevent premature evaporation of the refrigerant in the connecting pipe 110. The specific installation position is determined by those skilled in the relevant art.

[0169] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
