The uniformity of the thawing process is crucial. For example, cryogenic refrigeration can significantly extend the storage life of plasma; at -50°C, plasma can be stored for up to four years. Before use, cryogenically refrigerated plasma must be thawed in a thawing machine. During the thawing process, localized temperatures that are too low can cause fibrinogen precipitation and inactivate coagulation factors, while localized temperatures that are too high can denature plasma proteins and inactivate coagulation factors.

The main case is a constant temperature water tank, and a heating device is provided inside the main case. The heating device heats the water in the lower case to meet the water temperature requirements; the large-flux water pump circulates the water in the main case and the water in the sub-case, and the melting uniformity of the melting machine is improved through the cooperation of the main case, the sub-case and the large-flux water pump.

[0046] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0047] The embodiment of the present disclosure provides a melting machine, which has good melting uniformity and is smaller in size while having the same melting tank volume.

[0048] Combine Figure 1 and Figure 2 The melting machine includes a chassis 100, a circulation pump 200 and a heating component 300.

[0049] The chassis 100 is provided with a melting tank 101 and a circulation channel 102. The melting tank 101 can accommodate a heat transfer medium. The circulation channel inlet 1021 and the circulation channel outlet 1022 of the circulation channel 102 are both connected to the melting tank 101. The circulation pump 200 is disposed outside the chassis 100, with its suction end connected to the melting tank 101 and its output end connected to the circulation channel inlet 1021. The circulation pump 200 is capable of driving the heat transfer medium to circulate between the circulation channel 102 and the melting tank 101 through the circulation channel inlet 1021 and the circulation channel outlet 1022. The heating assembly 300 is capable of heating the heat transfer medium within the melter.

[0050] The melting machine provided by the embodiment of the present disclosure includes a chassis 100, a circulation pump 200 and a heating component 300. The heating component 300 is capable of heating the heat transfer medium filled in the melting machine; the chassis 100 is provided with a melting tank 101 and a circulation channel 102, and the circulation channel inlet 1021 and the circulation channel outlet 1022 are both connected to the melting tank 101; the circulation pump 200 is capable of driving the heat transfer medium to circulate between the circulation channel 102 and the melting tank 101, which is conducive to improving the uniformity of the heat transfer medium temperature, thereby being able to use the heat transfer medium to uniformly heat the items to be melted, thereby improving the melting uniformity of the melting machine. At the same time, the entire melting process of the melting machine provided by the embodiment of the present disclosure is implemented in the chassis 100, without the need to set up a sub-chassis as in the prior art. Therefore, under the premise of having the same melting tank volume, the melting machine provided by the embodiment of the present disclosure is smaller in size. In addition, the circulation pump 200 is arranged outside the chassis 100, which is conducive to further reducing the volume of the melting machine.

[0051] The housing 100 constitutes the main body of the melting machine.

[0052] Alternatively, see Figure 3 The chassis 100 includes a bottom wall 103, a first side wall 104, a second side wall 105, a third side wall 106, and a fourth side wall 107. The bottom wall 103, the first side wall 104, the second side wall 105, the third side wall 106, and the fourth side wall 107 enclose and define a melting groove 101.

[0053] The first side wall 104 and the second side wall 105 are oppositely arranged, and the third side wall 106 and the fourth side wall 107 are oppositely arranged.

[0054] In some embodiments, combined Figure 2 and Figure 4 A reflux port 1041 is provided at the upper portion of the first side wall 104, through which the suction end of the circulation pump 200 communicates with the melting tank 101. The circulation channel 102 is provided on the bottom wall 103, and a circulation channel outlet 1022 is provided on the upper side plate 1031 of the bottom wall 103, and a circulation channel inlet 1021 is provided on the first end plate 1032 of the bottom wall 103.

[0055] With this arrangement, during the melting process of the melter, the flow path of the heat transfer medium can cover a larger area within the melting tank 101, which is conducive to improving the uniformity of the heat transfer medium temperature and enhancing the melting effect of the melter. At the same time, the heat transfer medium in the melting tank 101 flows from bottom to top through the items to be melted in the melting tank 101, which is conducive to increasing the replacement rate of the heat transfer medium around the items to be melted, thereby improving the melting effect of the items to be melted.

[0056] Alternatively, see Figure 2 The bottom wall 103 further includes a second end plate 1033. The second end plate 1033 is disposed opposite the first end plate 1032. The heat transfer medium in the circulation channel 102 flows in a first direction, from the first end plate 1032 to the second end plate 1033. A plurality of circulation channel outlets 1022 are provided, and the plurality of circulation channel outlets 1022 are evenly distributed along the first direction. This arrangement allows the heat transfer medium in the circulation channel 102 to evenly enter the melting tank 101 through the plurality of circulation channel outlets 1022.

[0057] In some embodiments, combined Figure 2 and Figure 5The melting machine further includes one or more guide plates 400, which are disposed in the circulation channel 102 and correspond one-to-one with the circulation channel outlet 1022. The guide plates 400 are disposed on the side of the circulation channel outlet 1022 near the second end plate 1033 and extend toward the side of the first end plate 1032. The provision of the guide plates 400 disrupts the laminar flow of the heat transfer medium in the circulation channel 102, reducing the laminar flow in the first direction in the circulation channel 102 and increasing the amount of heat transfer medium flowing upward, thereby evenly guiding the heat transfer medium in the circulation channel 102 to the melting tank 101.

[0058] Assuming that the guide plate 400 is not provided, the heat transfer medium flows into the circulation channel 102 through the first end plate 1032. During the flow along the first direction, the heat transfer medium is mainly laminar flow, and only a small portion of the heat transfer medium flows into the melting tank 101 through the circulation channel outlet 1022. When the heat transfer medium flows to the second end plate 1033, the heat transfer medium cannot continue to flow forward, and a large amount of heat transfer medium flows into the melting tank 101 from the circulation channel outlet 1022 near the second end plate 1033, which affects the uniformity of melting.

[0059] In some embodiments, combined Figure 2 and Figure 5 The heating assembly 300 includes one or more first heating tubes 301, which are disposed in the middle of the circulation channel 102. The guide plate 400 includes a fixed end 401 and a free end 402. The fixed end 401 is fixed to the side of the upper plate 1031 facing the circulation channel 102, and the free end 402 is located above the first heating tubes 301.

[0060] By providing the first heating tube 301 in the circulation channel 102, the heat transfer medium flowing through the circulation channel 102 can be heated, and the heated heat transfer medium can then be evenly transported to the melting tank 101 through the circulation channel outlet 1022, thereby improving the uniformity of melting. In addition, the fixed end 401 of the guide plate 400 is fixed to the side of the upper side plate 1031 facing the circulation channel 102, and the free end 402 of the guide plate 400 is located above the first heating tube 301. This can not only guide the heat transfer medium in the circulation channel 102 to the melting tank 101, but also reserve sufficient space for the heat transfer medium to flow in the first direction. In this way, the heat transfer medium in the circulation channel 102 can be evenly guided to the melting tank 101 through the multiple circulation channel outlets 1022. If the free end 402 of a guide plate 400 extends to the lower side plate 1034, then only a small amount of heat transfer medium can pass through the location of the guide plate 400, and the heat transfer medium is concentrated at the circulation channel outlet 1022 between the guide plate 400 and the first end plate 1032 and enters the melting tank 101, affecting the uniformity of the heat transfer medium temperature in the melting tank 101, and thus affecting the melting effect.

[0061] The first heating tube 301 is located within the circulation channel 102. The heat transfer medium / airflow flows through the first heating tube 301, exchanging heat with it. This allows the first heating tube 301 to more efficiently heat the heat transfer medium, ensuring the required melting temperature. Furthermore, the placement of the first heating tube 301 within the circulation channel 102 makes the melter more compact, reducing its size.

[0062] In some embodiments, combined Figure 2 and Figure 6 The melter also includes an output pipe 201. The inflow end of the output pipe 201 is connected to the output end of the circulation pump 200, and the outflow end of the output pipe 201 extends into the circulation channel 102 through the circulation channel inlet 1021. A premixing port 108 is provided on the side of the upper side plate 1031 near the first end plate 1032. The premixing port 108 connects the melting tank 101 and the circulation channel 102. The orthographic projection of the output pipe 201 on the upper side plate 1031 covers the premixing port 108.

[0063] Under the action of the circulation pump 200, the heat transfer medium flows at high speed in a first direction. This high-speed flow of the heat transfer medium causes a flow phenomenon, drawing the water flow at the rear end forward. The premixing port 108 is located above and behind the outflow end of the output pipe 201. The heat transfer medium enters the circulation channel 102 from the outflow end of the output pipe 201 and flows at high speed in the first direction. The high-speed flow of the heat transfer medium drives the heat transfer medium between the outflow end of the output pipe 201 and the first end plate 1032 to flow forward, and then the heat transfer medium in the melting tank 101 enters the circulation channel 102 through the premixing port 108. In this way, not only can the heat transfer medium between the outflow end of the output pipe 201 and the first end plate 1032 flow, but the heat transfer medium can also be sucked from the melting tank 101, achieving a premixing effect.

[0064] There will be a certain area with relatively low pressure around the fluid moving at high speed. In addition, the fluid will diffuse to the surroundings during the process of moving forward. Therefore, the outflow end and the rear of the output pipe 201 are the best negative pressure areas. The premixing port 108 is set behind the outflow end of the output pipe 201 for the best effect.

[0065] In some embodiments, combined Figure 3 and Figure 4 The melting machine further includes a reflux trough 500, which is disposed on a side of the first sidewall 104 away from the melting tank 101 and communicates with the melting tank 101 via a reflux port 1041. The suction end of the circulating pump 200 is connected to the reflux trough 500. This facilitates the suction of heat transfer medium from the melting tank 101 through the reflux trough 500 and the reflux port 1041, while also preventing interference with the flow path of the heat transfer medium within the melting tank 101.

[0066] Optionally, the return port 1041 is configured as a strip, and the return groove 500 covers the return port 1041. This configuration enables the heat transfer medium in the melting tank 101 to flow evenly to the return port 1041.

[0067] Optionally, multiple return ports 1041 are provided, and the multiple return ports 1041 are evenly distributed along the first direction on the first sidewall 104, and the return groove 500 covers the multiple return ports 1041. Such a configuration can make the heat transfer medium in the melting groove 101 flow to the return ports 1041 more evenly.

[0068] For example, combining Figure 3 and Figure 4 Two return ports 1041 are provided, evenly distributed along the first direction on the first sidewall 104, and the return groove 500 covers the two return ports 1041. This configuration allows the heat transfer medium in the melting tank 101 to flow more evenly to the return ports 1041. The suction end of the circulation pump 200 is connected to the return groove 500. Under the suction force of the circulation pump 200, the heat transfer medium in the melting tank 101 flows from the two strip-shaped return ports 1041 to the return groove 500, and then flows into the circulation pump 200.

[0069] If the suction end of the circulation pump 200 is directly connected to the melting tank 101 and the suction force of the circulation pump 200 is large, the circulating medium in the melting tank 101 will flow to the connection between the suction end of the circulation pump and the melting tank 101, affecting the uniformity of the heat transfer medium distribution.

[0070] In some embodiments, the circulating pump 200 is a circulating heating pump that can drive and / or heat the heat transfer medium. By configuring the circulating pump 200 as a circulating heating pump, the heat transfer medium can be heated and driven, and heating of the heat transfer medium can be achieved without the need for a heat transfer module.

[0071] In some embodiments, combined Figure 6 and Figure 7 The circulating heating pump includes a pump housing 202, blades 203, a second heating tube 204, and a drive motor 205. The pump housing 202 is provided with a receiving cavity. Blades 203 are disposed in the receiving cavity and are capable of rotating to drive the flow of a heat transfer medium. A second heating tube 204 is disposed in the receiving cavity and is capable of heating the heat transfer medium flowing through the pump housing 202. The output shaft of the drive motor 205 is connected to the blades 203. This arrangement enables heating and driving of the heat transfer medium.

[0072] Optionally, the second heating tube 204 is arranged around the accommodating cavity. In this way, the second heating tube 204 can be used to evenly heat the heat transfer medium in the accommodating cavity.

[0073] In some embodiments, the pump housing is provided with a suction port and an output port, and the melter further comprises a suction pipe 206, which connects the suction port and the reflux tank 500. The first end of the output pipe 201 is connected to the output port.

[0074] In some embodiments, see Figure 1 The melting machine further includes a fixed support 700 for fixing the object to be melted. The fixed support 700 can be driven to reciprocate within the melting tank 101, thereby driving the object to be melted to reciprocate within the melting tank 101. This arrangement can quickly replace the heat transfer medium around the object to be melted, thereby improving the melting effect of the object to be melted.

[0075] In some embodiments, see Figure 1 and Figure 8 The melting machine also includes a driving assembly 600 for driving the fixed bracket to reciprocate, and the fixed bracket 700 includes a bracket body 701, an extension portion 702 and a connecting frame 703.

[0076] The first end of the extension portion 702 is fixedly connected to the bracket body 701, and the second end of the extension portion 702 extends to the outside of the chassis 100. The connecting frame 703 is vertically arranged at the second end of the extension portion 702 and connected to the driving assembly 600.

[0077] Such a configuration facilitates connection with the drive assembly 600 so that the drive assembly 600 drives the fixed bracket 700 to reciprocate in the melting tank 101. The fixed bracket 700 drives the object to be melted to reciprocate, which can accelerate the flow of heat transfer medium / airflow around the object to be melted, so that the object to be melted can be heated / dried more efficiently and evenly.

[0078] In some embodiments, see Figure 7 The support body 701 includes a main beam 7011 and multiple secondary beams 7012. The main beam 7011 extends parallel to the direction of reciprocation of the fixed support 700. The secondary beams 7012 are evenly distributed on both sides of the main beam 7011 and are parallel to each other. The main beam 7011 and the secondary beams 7012 are fixedly connected by multiple longitudinal beams 7013. The longitudinal beams 7013 are parallel to each other, and each longitudinal beam 7013 is connected to the main beam 7011 and all the secondary beams 7012. This arrangement ensures the stability and firmness of the fixed support 700, effectively securing the items to be melted.

[0079] Optionally, the extension portion 702 is fixedly connected to one end of the main beam 7011. This arrangement enables the support body 701 to reciprocate more stably, and avoids the support body 701 from tilting due to uneven force.

[0080] Alternatively, see Figure 1 and Figure 8 The melting machine also includes one or more second rails disposed on the sidewalls of the chassis 100. One or more second sliding members 704 are provided corresponding to the fixed brackets 700. The second sliding members 704 are adapted to slide along the corresponding second rails, with the second rails extending parallel to the direction of reciprocating motion of the fixed brackets 700. This arrangement ensures a more stable and smooth reciprocating motion of the fixed brackets 700.

[0081] Optionally, combined Figure 1 and Figure 8 The melter includes two second rails, one located on the first sidewall 104 and the other on the second sidewall 105. Accordingly, the fixed bracket 700 is equipped with two second sliding members 704, which are respectively attached to the two outermost secondary beams 7012. The secondary beams 7012 are parallel to the first and second sidewalls 104, 105. This arrangement ensures a more stable and smooth reciprocating motion of the fixed bracket 700.

[0082] Optionally, two second tracks are disposed on the first sidewall 104 and the second sidewall 105, respectively, facing the melting tank 101. Each second track has an upward-opening second track groove at its upper end. Second rollers are disposed on the side of the second sliding member 704 facing away from the melting tank 101. These second rollers are mounted on the upper ends of the second tracks and enter corresponding second track grooves, sliding along the second tracks. This arrangement allows the fixed bracket 700 to reciprocate along a predetermined path, preventing the fixed bracket 700 from being derailed by lateral unbalanced forces.

[0083] Optionally, two second rails are respectively provided at the upper end of the first side wall 104 and the upper end of the second side wall 105. This arrangement can avoid being affected by the heat transfer medium in the melting tank 101, thereby improving the service life and reliability of the second rails.

[0084] Optionally, the fixed support 700 further includes one or more first side frames 705 and second side frames 706. Multiple first side frames 705 and multiple second side frames 706 are provided on the sides of two adjacent crossbeams facing each other. One or more first fixing slots are provided on the side of the first side frame 705 facing the corresponding second side frame 706, and one or more second fixing slots are provided on the side of the second side frame 706 facing the corresponding first side frame 705. The first and second fixing slots enable the object to be melted to be secured to the support body 701. When the object to be melted is secured to the support body 701, the object to be melted is perpendicular to the direction of movement of the support body 701. Here, the crossbeams include a main crossbeam 7011 and a secondary crossbeam 7012. This arrangement helps enhance the agitation effect of the heat transfer medium and further improves melting uniformity.

[0085] The driving assembly 600 can drive the fixing bracket 700 to reciprocate in the melting tank 101 .

[0086] In some embodiments, see Figure 6 The drive assembly 600 includes a driven rotor 601 and a free rotor 602. The end surface of the free rotor 602 is adjacent to the end surface of the driven rotor 601. The free rotor 602 is rotatably mounted on the driven rotor 601 via a fixed shaft, and the free rotor 602 is offset from the center of the driven rotor 601. The circumference of the free rotor 602 is adapted to connect with the connecting frame 703. The driven rotor 601 can be driven to rotate, thereby driving the free rotor 602 to move, thereby driving the connecting frame 703 to reciprocate. The connecting frame 703 and the free rotor 602 are coplanar, and the direction of movement of the free rotor 602 is consistent with that of the connecting frame 703.

[0087] Optionally, the diameter of the free rotor 602 is equal to the inner diameter of the connecting frame 703. With this arrangement, the driven rotor 601 and the free rotor 602 can cooperate to smoothly push the connecting frame 703 to reciprocate.

[0088] In some embodiments, see Figure 6 The drive assembly 600 further includes a track plate 603, which is vertically disposed on the outer sidewall of the fourth sidewall 107. A driven rotor 601 and one or more first tracks 604 are disposed on a first side of the track plate 603. The free rotor 602 is disposed on a side of the driven rotor 601 away from the track plate 603. A connecting frame 703 is adapted to slide along the first tracks 604. This arrangement provides support and position limiting for the driven rotor 601 and the free rotor 602, ensuring that the connecting frame 703 moves along a predetermined trajectory and preventing deviation in the trajectory of the connecting frame 703.

[0089] Optionally, both upper and lower ends of the track plate 603 are provided with first tracks 604, which are groove tracks, and the opening of the groove tracks faces the connecting frame 703. Both ends of the connecting frame 703 are adapted to enter the corresponding groove tracks to slide along the corresponding groove tracks.

[0090] Optionally, one or more first sliding members 7031 are provided at both ends of the connection frame 703. By providing the first sliding members 7031, the friction between the connection frame 703 and the first track 604 can be reduced, so that the connection frame 703 can move more smoothly along the first track 604.

[0091] Optionally, the first sliding member 7031 is a rolling bearing, which can effectively reduce the friction between the first sliding member 7031 and the first track 604 and is cheap and readily available.

[0092] Optionally, the drive assembly 600 further includes a motor mounting plate and a motor, the motor mounting plate being horizontally disposed on the second side of the track plate; the motor being mounted on the motor mounting plate, and the motor's drive shaft being connected to the rotation center of the driven rotor 601. This arrangement enables driving of the driven rotor 601 while also reducing the size of the drive assembly 600, thereby reducing the size of the melter.

[0093] Optionally, the driven rotor 601 is configured as a disk, and the rotation center of the driven rotor 601 is the center point of the disk. The free rotor 602 is configured to deviate from the center point of the driven rotor 601 .

[0094] In some embodiments, the melter is equipped with n melting tanks, where n ≥ 1 and n is a positive integer. If n ≥ 2, the n melting tanks are separated by n-1 partitions. Each melting tank is independently equipped with a circulation channel 102, a circulation pump 200, and a heating assembly 300. This arrangement allows the temperature of each melting tank to be independently controlled, meeting the different temperature requirements of the items to be melted.

[0095] Optionally, n melting tanks are arranged in parallel, and the extending direction of the melting tanks is parallel to the movement direction of the fixing bracket 700. The n melting tanks share the fixing bracket 700 and the driving assembly 600. In this way, the temperature uniformity of the heat transfer medium in the n melting tanks can be improved and costs can be saved.
