[0079] The present invention also provides an operating method for a negative pressure heat exchange device, including the following specific steps:

[0080] Step 1: When heat exchange is required, the material box is filled with material and inserted into the heat exchange box. When the material box enters the heat exchange box, it comes into contact with the bonding frame. Then, under the action of the first spring and the connecting rod, the bonding frame and the material box are bonded together. Then, the rotating column drives the limiting column to slide and insert into the inner cavity of the assembly base to lock and fix the material box. Then, the insertion tube is inserted into the inside of the connecting tube, and the locking cylinder is threaded into the connecting tube, so that the inner cavity of the material box is connected to the inside of the first tube.

[0081] Step 2: Start the vacuum pump to perform a vacuuming operation. Simultaneously, start the pump body to allow the heat exchange medium to circulate inside the flat tube, heat conduction tube, and third tube. Gas is introduced through the inlet pipe, and the control valve is opened to connect the inside of the first tube. The vacuum pump then evacuates the inside of the material box through the first tube, telescopic tube, through-tube, and connecting tube. After setting the time, close the control valve, and the gas enters the vacuum pump. Driven and compressed by the vacuum pump, high-temperature gas is generated and discharged from the exhaust pipe, allowing the high-temperature gas to enter the heat exchange box. The high-temperature gas enters the heat exchange tube and is then discharged through the second tube. The heat exchange tube performs heat exchange with the high-temperature gas, thereby transferring heat to the heat exchange column.

[0082] Step 3: The heat exchange column then transfers heat to the heat-conducting pipe. As the heat exchange medium passes through this section of the heat-conducting pipe, it undergoes heat exchange, causing the heated heat exchange medium to flow to the flat tube. The flat tube then exchanges heat with the heat-conducting frame, which transfers the heat to the bonding frame. The bonding frame, after heat exchange, heats the material box, thereby heating the material inside the material box. In addition, the gas entering the second pipe enters the auxiliary box, where it exchanges heat with the residual heat in the gas to heat the water inside the heat-conducting box. The heat is then discharged through the exhaust pipe.

[0083] The technical effects and advantages of this invention are as follows:

[0084] (1) By utilizing the negative pressure mechanism, heat exchange mechanism and exchange mechanism, the negative pressure mechanism compresses the external gas to a high temperature and enters the heat exchange box for heat exchange. The vacuum pump performs a vacuum operation on the inside of the material box to reduce the boiling point of the material. The exchange mechanism heats the material inside the material box, which is conducive to the heat exchange and negative pressure working together, making it easier for the material to achieve efficient heat exchange at low temperature, improving heat exchange efficiency, and also facilitating the utilization of the gas extracted from the inside of the material box.

[0085] (2) The present invention utilizes a combination of heat exchange box, second tube, support column, support column, heat exchange column, insulation column, heat exchange tube and support frame. The heat exchange box allows the compressed high-temperature gas to enter its interior for heat exchange with the heat exchange tube. The heat exchange tube heats the heat exchange column, the heat exchange column continuously heats the heat-conducting tube, and the support frame supports the support column. This facilitates the heat exchange operation of the compressed high-temperature gas of the vacuum pump and makes heat exchange operation easier.

[0086] (3) The present invention utilizes a combination of heat exchange box, heat insulation frame, flat tube, heat conduction tube, pump body, third tube, heat conduction frame and bonding frame. The pump body circulates the heat exchange medium in the flat tube, heat conduction tube and third tube to carry away the heat of the heat conduction tube. The heat exchange medium transfers heat to the flat tube. The flat tube continuously heats the heat conduction frame. The heat conduction frame transfers heat to the bonding frame to continuously heat the material box. The elastic force of the first spring makes the bonding frame tightly bonded to the material box, which is conducive to heat exchange of the material inside the material box to heat the material. It is easy to adapt to heat exchange of different kinds of materials.

[0087] (4) By using the clamping plate, connector, fixing column, square plate, positioning seat, limiting component and second spring, the clamping plate vertically clamps and limits the support frame, the connector vertically limits and fixes the insulation frame while the clamping plate limits the support frame, and the limiting component locks the fixing column to the positioning seat to limit and fix the clamping plate. This is beneficial for installing and fixing the insulation frame and supporting the fixing mechanism at the same time as installing and fixing the support frame. This is also beneficial for the internal maintenance of the heat exchange box and the maintenance of the flat tube.

[0088] (5) The present invention utilizes a combination of telescopic tube, insert tube, connecting tube, locking cylinder, first ring body and second ring body. The telescopic tube allows the insert tube to move up and down, and the insert tube is connected to the inside of the connecting tube. The locking cylinder fixes the insert tube to the connecting tube, which facilitates the connection between the inside of the material box and the inside of the first tube, and makes it easier to perform vacuuming operation on the inside of the material box.

[0089] (6) The present invention utilizes a combination of an assembly base, a threaded base, a limiting post, a rotating post, and an anti-detachment ring. The assembly base supports the material box, and the limiting post locks and fixes the extension to the assembly base, which facilitates the installation and disassembly of the material box and makes it easy to remove and replace the material box to adapt to different materials.

[0090] (7) The present invention utilizes an auxiliary box, an exhaust pipe and a heat conduction box in combination. The auxiliary box allows the gas discharged from the second pipe to enter its interior, and the heat conduction box performs heat exchange operation on the residual heat inside the gas. After heat exchange, the gas is discharged, which helps to improve the utilization rate of heat in the gas. Attached Figure Description

[0114] Specifically, the auxiliary mechanism 8 includes an auxiliary box 81, an exhaust pipe 82, and a heat conduction box 83. The auxiliary box 81 is made of heat-insulating material.

[0115] Working principle of this invention:

[0116] When heat exchange is required, the material box 415 is used to hold the material and is inserted into the exchange box 41. When the material box 415 enters the exchange box 41, it comes into contact with the bonding frame 48. Then, under the action of the first spring 414 and the connecting rod 412, the bonding frame 48 is made to fit with the material box 415. Then, the rotating column 74 drives the limiting column 73 to slide and insert into the inner cavity of the assembly base 71 to lock and fix the material box 415. Then, the inserting tube 62 is inserted into the inside of the connecting tube 63, and the locking cylinder 64 is threadedly connected to the connecting tube 63 to realize the connection between the inner cavity of the material box 415 and the inside of the first tube 25.

[0117] The vacuum pump 22 is activated to perform a vacuuming operation, and the pump body 45 is started simultaneously. This causes the heat exchange medium to circulate inside the flat tube 43, the heat conduction tube 44, and the third tube 46. Gas is introduced through the inlet pipe 23, and the control valve 26 is opened to connect the inside of the first tube 25. The vacuum pump 22 then performs a vacuuming operation inside the material box 415 through the first tube 25, the telescopic tube 61, the through tube 62, and the connecting tube 63. After a set time, the control valve 26 is closed, and gas enters the vacuum pump 22. Under the drive and compression of the vacuum pump 22, high-temperature gas is generated and discharged from the exhaust pipe 24. This allows the high-temperature gas to enter the heat exchange box 31 and the heat exchange tube 37, and then be discharged through the second tube 32. The heat exchange tube 37 performs heat exchange with the high-temperature gas, thereby transferring heat to the heat exchange column 35.

[0118] Then, the heat exchange column 35 transfers heat to the heat-conducting pipe 44. As the heat exchange medium passes through this part of the heat-conducting pipe 44, it undergoes heat exchange, causing the heated heat exchange medium to flow to the flat pipe 43. The flat pipe 43 then exchanges heat with the heat-conducting frame 47, which transfers heat to the bonding frame 48. The heat-exchanged bonding frame 48 then heats the material box 415 to heat the material inside the material box 415. In addition, the gas that enters the second pipe 32 enters the auxiliary box 81. The heat-conducting box 83 then exchanges heat with the residual heat in the gas to heat the water inside the heat-conducting box 83, and then it is discharged through the gas outlet pipe 82.
