[0039] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0040] 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.

[0041] Melt melters are categorized as water-bath and air-bath types, depending on the heat exchange medium. In air-bath melters, a fan drives the hot air, which moves at a faster rate. The distance between gas molecules is larger, and the intermolecular forces are smaller, resulting in stronger thermal motion. The combined effects of air flow and the thermal motion of gas molecules ensure better temperature uniformity within the melter. In water-bath melters, the water flows more slowly. The distance between water molecules is smaller, resulting in stronger intermolecular forces, resulting in weaker thermal motion. The temperature uniformity of water-bath melters is weaker than that of air-bath melters.

[0042] In order to further improve the temperature uniformity of the water bath melting machine, combined with Figure 1-4 As shown, an embodiment of the present disclosure provides a melting machine, including a box body 100, a partition 110, a water flow driving device 200 and a swinging device 300, wherein the box body 100 constructs an accommodating space; the partition 110 divides the accommodating space into a heating space 120 and an operating space 130, and the partition 110 is provided with a water outlet 111; the water flow driving device 200 is used to drive the water in the heating space 120 to flow to the operating space 130 through the water outlet 111; the swinging device 300 is arranged at the water outlet 111, and is used to change the water outlet angle of the water outlet 111.

[0043] In the embodiment of the present disclosure, the plasma thawing machine includes a housing 100, which defines a storage space. A partition 110 is provided in the housing 100, dividing the storage space into a heating space 120 and an operating space 130. The operating space 130 is used to place frozen plasma, and an operating window is provided in the operating space 130 to facilitate users to take out plasma bags. A heating device 121 is provided in the heating space 120 to increase the temperature of the water in the heating space 120. The partition 110 is provided with a water outlet 111 to connect the heating space 120 to the operating space 130. Specifically, the water flow driving device 200 drives the hot water in the heating space 120 to flow to the operating space 130, thereby increasing the water temperature in the operating space 130. The water in the operating space 130 contacts the plasma bag for heat exchange, thereby melting the plasma.

[0044] When water flows into the heat exchange space, it has a certain initial velocity and direction. As it flows through the operating chamber 100, it cannot fully and evenly exchange heat with the water at various locations within the operating chamber 130. Consequently, temperature differences exist at different locations within the operating chamber 100. This temperature difference hinders the melter's ability to control the water temperature in the operating chamber 130. When multiple bags of plasma are placed simultaneously in the operating chamber, this temperature difference can cause temperatures near some bags to be too high and others to be too low.

[0045] The oscillating device 300 is provided at the water outlet 111 and is used to change the water outlet angle of the water outlet 111. As a mode of use, the oscillating device 300 periodically changes the water outlet angle of the water outlet 111. When the water from the heating space 120 enters the operating space 130, the water outlet angle of the water flow changes periodically. The water in the heating space 120 has different water outlet angles and can flow to various positions in the operating space 130, thereby improving the temperature uniformity of the operating space 130. The water outlet angle of the water outlet 111 changes periodically. Compared with the form in which the water outlet angle remains unchanged, the turbulence of the water in the operating space 130 increases and the laminar flow decreases, which can further improve the temperature uniformity of the operating space 130.

[0046] When using the melting machine provided by the embodiment of the present disclosure, the heating space 120 and the operating space 130 are located in the same box 100, and the overall structure of the melting machine is simple and beautiful; the water outlet 111 is provided with a swinging device 300, and the water outlet angle of the water outlet 111 can make the water flowing out of the water outlet flow evenly to various positions of the operating space 130, which can improve the temperature uniformity of the operating space 130; when the swinging device 300 changes the water outlet angle, the laminar flow of water in the operating space 130 is reduced and the turbulent flow is increased, which can further improve the temperature uniformity of the operating space 130.

[0047] Optionally, the slurry melter further includes a water return pipe 150 , a first end of which is connected to the operating space 130 , and a second end of which is connected to the heating space 120 .

[0048] The return pipe 150 connects the operating space 130 and the heating space 120. Water from the operating space 130 returns to the heating space 120 through the return pipe 150. This arrangement allows water to circulate between the operating space 130 and the heating space 120, reducing the water consumption of the melter. Furthermore, the circulation of water between the operating space 130 and the heating space 120 further enhances heat convection within the operating space 130, thereby achieving a more uniform temperature within the operating space 130.

[0049] Optionally, the first end of the return pipe 150 is located below the highest water level of the operating space 130 and at a preset distance from the bottom of the operating space 130 .

[0050] In the operating space 130, when the water flow is still or at a low flow rate, the water with higher temperature floats up while the water with lower temperature falls due to the difference in cold and hot density. When the water in the operating space 130 flows at a faster speed, the effect of the difference in cold and hot density of the water is not obvious, and the laminar flow effect of the water entering the operating space 130 and flowing horizontally along the partition 110 is more obvious. If the return water port is opened on the partition 110, a portion of the water flowing out through the water outlet 111 will return to the heating space 120 from the return water port along the upper surface of the partition 110. This will cause the temperature of the operating space 130 near the partition 110 to be higher and the temperature of the position away from the partition 110 to be lower. In addition, at the position close to the open port, water evaporation will absorb heat, which will further increase the temperature difference between the top and bottom of the operating space 130. The first end of the return water pipe 150 is the return water outlet, which is a preset distance from the bottom, so that the water with lower temperature in the operating space 130 can return to the heating space 120, thereby improving the heat exchange efficiency between the water and the heating device 121, and reducing the temperature difference between the upper and lower layers of water in the operating space 130.

[0051] Optionally, the partition 110 is arranged horizontally, the heating space 120 is located below the operating space 130 , the second end of the return pipe 150 corresponds to the first end of the partition 110 , and the water outlet 111 is opened at the second end of the partition 110 .

[0052] The partition 110 is arranged horizontally. Above the partition 110 is the operating space 130, and below the partition 110 is the heating space 120. Heat is exchanged between the water in the heating space 120 and the water in the operating space 130 through the partition 110 on the upper and lower surfaces. As the water in the operating space 130 near the partition 110 increases in temperature, its density decreases. Due to the difference in density between hot and cold water, it rises upward, not only raising the temperature of the operating space 130 but also creating convection through the rising water, which uniformly increases the temperature of the operating space 130. The top of the housing 100 is open, serving as an access window to the operating space 130, allowing users to access plasma bags through the opening. The first and second ends of the partition 110 are defined along its length or width. The second end of the return pipe 150 corresponds to the first end of the partition 110, and the water outlet 111 is located at the second end of the partition 110. This creates a long distance between the water inlet and outlet points of the heating space 120. This allows the water to travel a longer distance in the heating space 120, thereby fully exchanging heat with the heating device 121 disposed in the heating space 120. The distance between the water inlet and outlet of the heating space 120 is longer, and accordingly, the distance between the water inlet and outlet of the operating space 130 is also longer. This allows the water entering the operating space 130 to travel a longer distance in the operating space 130, thereby fully exchanging heat with the water in the operating space 130, thereby improving the temperature uniformity of the operating space 130.

[0053] Optionally, the swinging device 300 includes a rotating shaft 310, a guide plate 320 and a swinging motor 330, wherein the rotating shaft 310 is rotatably arranged at the water outlet 111; the guide plate 320 is fixed to the rotating shaft 310, and when the rotating shaft 310 rotates, the guide plate 320 rotates with the rotating shaft 310; the swinging motor 330 has an output shaft drivingly connected to the rotating shaft 310.

[0054] The rotating shaft 310 is fixedly connected to the guide plate 320. The rotating shaft 310 is used to fix the guide plate 320 and drive the guide plate 320 to rotate. The rotating shaft 310 is arranged at the water outlet 111, which means that the position of the rotating shaft 310 corresponds to the water outlet 111. The rotating shaft 310 can be arranged inside the water outlet 111, or above or below the water outlet 111. The output shaft of the swing drive motor 210 is driven and connected to the rotating shaft 310. When the swing motor 330 rotates, it drives the rotating shaft 310 to rotate, and further drives the guide plate 320 to rotate, thereby changing the water outlet angle of the water outlet 111. In some cases, the rotating shaft 310 performs a circular motion, and the guide plate 320 performs a circular motion with the rotating shaft 310. In this way, the water outlet angle of the water outlet 111 can be periodically changed in a relatively simple manner. In other cases, the output shaft of the swing drive motor 210 reciprocates at a certain angle, thereby driving the rotating shaft 310 to reciprocate at the same angle, thereby driving the guide plate 320 to oscillate at the same angle. Compared with circular motion, the swinging motion of the guide plate 320 is less likely to interfere with other components of the melter, the guide plate 320 can be larger, and the installation position of the guide plate 320 is more flexible.

[0055] Optionally, the length of the water outlet 111 is greater than the width of the water outlet 111 , the length direction of the rotating shaft 310 is along the length direction of the water outlet 111 , and the length direction of the guide plate 320 is along the length direction of the rotating shaft 310 .

[0056] The length of the water outlet 111 is greater than the width of the water outlet 111. For example, the water outlet 111 is a slit. Compared with the form of opening multiple water outlets 111, this can increase the distance of water in the heating space 120 and increase the conductive cross-sectional area of ​​the water outlet 111. The length direction of the rotating shaft 310 is along the length direction of the water outlet 111, and the length direction of the guide plate 320 is along the length direction of the rotating shaft 310. The width direction of the guide plate 320 is along the water outlet direction of the water outlet 111. With such a setting, the torque required to drive the guide plate 320 to rotate is small, and the guide plate 320 is easy to drive. The length of the guide plate 320 corresponds to the length of the water outlet 111, so that all the water flowing through the water outlet 111 has its flow direction changed under the guiding action of the guide plate 320. With such a setting, the swing device 300 can achieve a better water mixing effect.

[0057] Optionally, the melting machine also includes a guide plate 350, a first end of which is fixed to the inner wall of the box body 100, and the other end extends obliquely upward to above the water outlet 111, and the rotating shaft 310 is rotatably arranged at the second end of the guide plate 350, and the first end of the guide plate 320 is fixed to the rotating shaft 310, and the second end is a free end.

[0058] The water outlet 111 is close to the first inner wall of the housing 100, and the guide plate 350 extends inward and upward from the first inner wall of the housing 100. The length of the guide plate 350 corresponds to the length of the water outlet 111, and it is inclined upward from the first end to the second end of the partition 110. After the water flows out of the water outlet 111, it flows upward along the water outlet 111 and initially changes its flow direction under the wall effect of the guide plate. The guide plate 320 is spliced ​​with the guide plate 350 through the rotating shaft 310. After the water contacts the guide plate 320, it flows along the width direction of the guide plate 320. Driven by the swing motor 330, the guide plate 320 swings back and forth periodically, and the flow angle of the water also changes periodically, so that it flows evenly to various positions of the operating space 130. With this arrangement, when the swing device 300 changes the water outlet direction of the water outlet 111 , the water velocity loss is small after being guided twice by the diversion panel and the guide plate 320 , so that the water can flow a longer distance in the operating space 130 .

[0059] Optionally, the projection of the rotation shaft 310 on the partition 110 is located inside the water outlet 111 along the width direction of the water outlet 111 .

[0060] The water outlet 111 is provided on the partition 110. When water flows out of the water outlet 111 under the drive of the water flow drive device 200, it has an initial upward velocity. The orthographic projection of the rotation axis 310 on the partition 110 can extend beyond the water outlet 111 in the longitudinal direction or be located within the water outlet 111, or within the water outlet 111 in the width direction. In this way, the water flowing upward from the water outlet 111 partially contacts the drainage plate and partially contacts the guide plate 320. This arrangement can reduce the kinetic energy loss of the water flow, which helps the water in the heating space 120 move a greater distance in the operating space 130.

[0061] Optionally, when the guide plate 320 rotates to the first position, it is parallel to the partition 110 , and the projection of the guide plate 320 on the partition 110 exceeds the water outlet 111 .

[0062] When the guide plate 320 is parallel to the partition 110, the water flowing out of the water outlet 111 flows laterally along the partition 110 and flows a longer distance due to the wall effect of the partition 110. This allows the water in the heating space 120 to flow laterally for a longer distance in the operating space 130. After the water flows laterally, it floats upward due to the difference in cold and hot densities, thereby being more evenly mixed with the water in the heating space 120. The guide plate 320 rotates downward from the first position, and the first end of the guide plate 320 is closer to the partition 110. The speed of the water flowing through the guide plate 320 increases after throttling, and it can move laterally a longer distance along the partition 110. When the guide plate 320 rotates upward from the first position, the water outlet cross-sectional area of ​​the water outlet 111 increases, the water flow rate decreases, and the flow rate increases. With this arrangement, the flow direction and distribution position of water entering the operating space 130 change significantly when the guide plate 320 swings to different angles, which can further improve the temperature uniformity of the operating space 130.

[0063] Optionally, the swing motor 330 is a stepping motor, and the swing motor 330 drives the guide plate 320 to swing back and forth.

[0064] A stepper motor is an electric motor that converts electrical pulse signals into corresponding angular or linear displacements. Each pulse signal causes the rotor to rotate one degree or advance one step. The output angular or linear displacement is proportional to the number of input pulses, and the rotational speed is proportional to the pulse frequency. The swing motor 330 is a stepper motor that can more conveniently and accurately control the deflector 320 to swing or move in a circular motion at a preset angle and pattern, allowing users to adapt the movement of the deflector 320 to different usage environments.

[0065] Optionally, the swing motor 330 is disposed in the operating space 130 , and the swing motor 330 is a waterproof motor.

[0066] The swing motor 330 is disposed in the operating space 130 , which facilitates assembly between the swing motor 330 and the rotating shaft 310 .

[0067] A transmission hole is opened on the side plate of the box body 100 , and a sealing sleeve is provided in the transmission hole. One end of the rotating shaft 310 passes through the sealing sleeve. The swing motor 330 is arranged outside the box body 100 and is driven and connected to the rotating shaft 310 .

[0068] By adopting such a configuration, water can be prevented from entering the swing motor 330 , thereby improving the safety of the pulp melting machine.

[0069] Optionally, the water flow driving device 200 includes a driving device and a propeller 220 , wherein the driving motor 210 is disposed in the return water pipe 150 or the heating space 120 ; and the propeller 220 is connected to the output shaft of the driving motor 210 .

[0070] When the drive motor 210 rotates, the propeller 220 rotates, pushing the water flow outward and backward along the propeller 220. The outward flow of water is constrained by the inner wall of the heating space 120, and after being mixed, it flows backward and flows to the operating space 130 through the water outlet 111. The water in the operating space 130 is replenished to the heating space 120 through the return pipe 150. Compared with the form of setting a water pump, the form of the propeller 220 does not have a rectifying structure, and there is more turbulence in the water flow pushed by the propeller 220. This can make the water temperature in the heating space 120 more uniform, and further, make the water temperature in the operating space 130 more uniform. In addition, the form of the propeller 220 has a simple structure and low cost.

[0071] Optionally, there are multiple return water pipes 150 and multiple driving devices, and the multiple driving devices correspond one-to-one to the multiple return water pipes 150 .

[0072] Water from the operating space 130 returns to the heating space 120 through multiple return pipes 150, forming multiple streams of water, thereby increasing the turbulence of the water flow in the operating space 130. The one-to-one correspondence between the drive device and the multiple return pipes 150 can improve the water driving effect and enhance the water circulation effect in the operating space 130 and the heating space 120.

[0073] Optionally, the melting machine further includes a support plate 140 , which is disposed in the heating space 120 to divide the heating space 120 into a plurality of water flow channels, each of which corresponds to a plurality of return water pipes 150 , and the ends of the plurality of water flow channels are connected to the water outlet 111 .

[0074] The support plate 140 is arranged in the heating space 120, and the top end of the support plate 140 is connected to the partition 110, and the bottom end is connected to the bottom plate of the heating space 120. The support plate 140 can improve the overall structural strength of the slurry melter. The support plate 140 also divides the heating space 120, so that multiple water flow channels are formed inside the heating space 120.
