Description

Technical Field

[0001] The utility model relates to the technical field of heating equipment, in particular to a plate-type heating device. Background Art

[0002] Pretreatment of soybean raw materials is crucial in soybean oil production. The raw material's moisture content, temperature, and softening degree directly impact the effectiveness of subsequent processes such as crushing, peeling, flaking, and puffing, ultimately determining the success of the extraction process. Currently, soybean conditioning processes in the industry often cause raw material blockage in the conditioning section, impacting the efficiency of the conditioning process and leading to low production efficiency. Utility Model Content

[0003] In view of this, the utility model provides a plate-type heating device to solve the technical problem that blockage easily occurs between heat transfer plates.

[0004] The utility model provides a plate-type heating device, comprising:

[0005] A shell, wherein a liquid inlet pipe and a liquid outlet pipe are provided on one side of the shell;

[0006] Multiple heat transfer plates are installed inside the shell, and a liquid inlet and a liquid outlet are respectively provided on the same side of the multiple heat transfer plates, and the liquid inlet is close to the liquid outlet, the liquid inlet is connected to the liquid inlet pipe, and the liquid outlet is connected to the liquid outlet pipe; the multiple heat transfer plates are arranged in parallel and at intervals inside the shell.

[0007] Beneficial Effects: By disposing a liquid inlet and outlet pipe on one side of the shell, and connecting them to the liquid inlet and outlet on the same side of the heat transfer plate, liquid can enter the heat transfer plate from the outside for heating or cooling before being discharged to the outside. By locating the liquid inlet close to the liquid outlet, liquid can flow along a predetermined path within the heat transfer plate, thereby ensuring efficient heat exchange. By arranging multiple heat transfer plates in parallel and at intervals within the shell, with sufficient space between the plates, soybeans can be effectively prevented from becoming clogged between the heat transfer plates during conditioning. Liquid can also flow between the different heat transfer plates, contacting more heat transfer surfaces, thereby improving heat exchange efficiency.

[0008] In an optional embodiment, the heat transfer plate is formed by welding at least two metal plates, and a pillow-shaped cavity is formed between the metal plates.

[0009] Beneficial Effects: By welding at least two metal plates to form a heat transfer plate and creating a pillow-shaped cavity between the plates, the internal surface area of the heat transfer plate is increased, thereby improving heat exchange efficiency. Furthermore, the pillow-shaped cavity creates turbulent flow within the fluid and provides structural strength to withstand internal fluid pressure and external forces.

[0010] In an optional embodiment, a plurality of welding points are provided on the heat transfer plate, and the welding points are arranged between two adjacent pillow-shaped cavities.

[0011] Beneficial Effects: The welds between adjacent pillow-shaped cavities enhance the structural strength of the heat transfer plate. When fluid flows or is subjected to external pressure, the welds help disperse stress, preventing deformation or cracking at weak points. They also create turbulence in the fluid, increasing mixing and thus improving heat exchange efficiency.

[0012] In an optional embodiment, a welding path is further provided on the heat transfer plate, and the welding path is arranged between the liquid inlet and the liquid outlet.

[0013] Beneficial effect: By setting a welding path on the heat transfer plate and setting it between the liquid inlet and the liquid outlet, it can be ensured that after the liquid enters the heat transfer plate from the liquid inlet, it can flow fully inside the heat transfer plate and then flow out of the heat transfer plate from the liquid outlet, avoiding the liquid entering the heat transfer plate from the liquid inlet and immediately flowing out from the liquid outlet close to the liquid inlet, thereby optimizing the heat transfer effect.

[0014] In an optional embodiment, the welding path includes a first welding path and a second welding path, the first welding path is arranged between the liquid inlet and the liquid outlet, and the first welding path extends from the side of the heat transfer plate in a direction away from the side; one end of the second welding path is connected to the first welding path and is perpendicular to the first welding path.

[0015] Beneficial Effects: By providing two welding paths, with the first path positioned between the liquid inlet and the liquid outlet, this prevents liquid from entering the heat transfer plate through the liquid inlet and then immediately flowing out of the outlet near the liquid inlet. Connecting one end of the second welding path to the first, perpendicular to the first, ensures that the liquid within the heat transfer plate flows along the predetermined path, further increasing fluid flow and heat exchange efficiency within the plate. Furthermore, the two welding paths ensure the structural strength and sealing of the heat transfer plate.

[0016] In an optional embodiment, a protective structure for preventing the heat transfer plate from being worn is provided above the heat transfer plate.

[0017] Beneficial effect: By setting up a protective structure above the heat transfer plate, it is possible to avoid scratches, wear and tear on the surface of the heat transfer plate and damage to the heat transfer plate structure caused by collision or friction between tiny particles, impurities or other components and the heat transfer plate in actual applications; the protective structure can play a blocking and buffering role, reducing the damage to the heat transfer plate caused by physical wear.

[0018] In an optional embodiment, the protective structure is made of stainless steel.

[0019] Benefits: By using stainless steel to create a protective structure, various heat transfer plate protection structures can be manufactured based on the plate's shape, size, and installation requirements. Furthermore, stainless steel's high strength and hardness allow it to withstand certain external forces and pressures, ensuring that the protective structure is not easily deformed or damaged during operation, ensuring that it can consistently protect the heat transfer plate.

[0020] In an optional embodiment, at least one opening is provided on the other side of the shell, and a transparent viewing mirror is installed on the opening.

[0021] Beneficial Effects: By providing an opening on the side of the housing opposite the water inlet and outlet pipes and installing a transparent sight glass in the opening, the internal conditions of the plate-type heating device can be observed through the transparent sight glass, providing real-time information on whether there are blockages during the soybean conditioning process. This facilitates the timely detection of abnormal conditions within the plate-type heating device and the implementation of appropriate measures to ensure its normal operation. By providing multiple openings and installing a transparent sight glass in each opening, the internal conditions of the plate-type heating device can be observed from different angles, providing more comprehensive information.

[0022] In an optional embodiment, a manhole is further provided on the shell, and the manhole and the transparent sight glass are arranged on the same side of the shell.

[0023] Beneficial Effects: By providing a manhole on the housing, personnel can more easily inspect, repair, and clean out accumulated materials inside the plate-type heating device. The manhole and the transparent window are located on the same side of the housing. While observing the internal operation of the plate-type heating device through the transparent window, personnel can directly enter the plate-type heating device through the manhole on the same side when further inspection or operation is required. This reduces the distance personnel need to move around the equipment and improves work efficiency.

[0024] In an optional embodiment, the distance between two adjacent heat transfer plates is 2.5 cm to 3.5 cm.

[0025] Beneficial effect: By setting a suitable spacing distance between two adjacent heat transfer plates, it is possible to effectively prevent the soybean raw material from being blocked between the heat transfer plates during conditioning, thereby effectively improving the conditioning efficiency of the soybean.

[0032] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0033] The following combination Figures 1 to 3 , describing the embodiments of the present utility model.

[0034] According to the embodiment of the present utility model, Figures 1 to 3As shown, a plate-type heating device is provided, comprising: a shell 1, with a liquid inlet pipe 4 and a liquid outlet pipe 5 provided on one side of the shell 1; a plurality of heat transfer plates 11 installed inside the shell 1, with a liquid inlet 111 and a liquid outlet 112 respectively provided on the same side of the plurality of heat transfer plates 11, and the liquid inlet 111 is close to the liquid outlet 112, the liquid inlet 111 is connected to the liquid inlet pipe 4, and the liquid outlet 112 is connected to the liquid outlet pipe 5; the plurality of heat transfer plates 11 are arranged in parallel and spaced apart inside the shell 1.

[0035] In this embodiment, a liquid inlet pipe 4 and a liquid outlet pipe 5 are provided on one side of the housing 1 and communicate with a liquid inlet 111 and a liquid outlet 112 provided on the same side of the heat transfer plate 11. This allows external liquid to enter through the liquid inlet pipe 4 and enter the heat transfer plate 11 through the liquid inlet 111 connected to the liquid inlet pipe 4. The liquid inside the heat transfer plate 11 then flows through the liquid outlet 112 into the liquid outlet pipe 5 connected to the liquid inlet 4, and finally is discharged to the outside through the liquid outlet 5. By arranging the liquid inlet 111 close to the liquid outlet 112, the liquid can flow along a predetermined path within the heat transfer plate 11, thereby ensuring efficient heat exchange. By arranging multiple heat transfer plates 11 in parallel and at intervals within the housing 1, sufficient space is created between the heat transfer plates 11. This effectively prevents soybeans from becoming clogged between the heat transfer plates 11 during conditioning. It also allows the liquid to flow between the different heat transfer plates 11, contacting more heat transfer surfaces, thereby improving heat exchange efficiency.

[0036] In one embodiment, the distance between two adjacent heat transfer plates 11 is 2.5 cm to 3.5 cm.

[0037] In this embodiment, the spacing between two adjacent heat transfer plates 11 can be 2.5 cm, 2.7 cm, 2.9 cm, 3.1 cm, 3.3 cm, 3.5 cm, etc.; the specific spacing can be set according to actual usage requirements. By setting an appropriate spacing between two adjacent heat transfer plates 11, blockage between the heat transfer plates 11 during conditioning of soybean raw materials can be effectively prevented, thereby effectively improving the conditioning efficiency of soybeans.

[0038] In one embodiment, the heat transfer plate 11 is formed by welding at least two metal plates 115 , and a pillow-shaped cavity 114 is formed between the metal plates 115 .

[0039] In this embodiment, the heat transfer plate 11 is formed by welding two metal plates 115 together, completely welded around the edges to form a sealed space. Welding the two metal plates 115 together achieves a high-strength connection, ensuring that the heat transfer plate 11 will not separate due to internal pressure or external forces during operation. Furthermore, a pillow-shaped cavity 114 is formed between the two metal plates 115, which increases the internal surface area of the heat transfer plate 11 and improves the efficiency of heat exchange. Furthermore, the pillow-shaped cavity 114 creates turbulent flow within the fluid and provides a certain structural strength to withstand internal fluid pressure and external forces.

[0040] In one embodiment, a plurality of welding points 113 are provided on the heat transfer plate 11 , and the welding points 113 are arranged between two adjacent pillow-shaped cavities 114 .

[0041] In this embodiment, the provision of multiple weld points 113 on the heat transfer plate 11 facilitates the formation of pillow-shaped cavities 114 within the heat transfer plate 11. Furthermore, the weld points 113 located between two adjacent pillow-shaped cavities 114 further enhance the structural strength of the heat transfer plate 11. When fluid flows within the heat transfer plate 11 or when subjected to external pressure, the weld points 113 help disperse stress, preventing deformation or rupture at weak points in the heat transfer plate 11. The weld points 113 also promote fluid turbulence, increasing fluid mixing and thereby improving heat exchange efficiency.

[0042] In one embodiment, a welding path 116 is further provided on the heat transfer plate 11 , and the welding path 116 is arranged between the liquid inlet 111 and the liquid outlet 112 .

[0043] In this embodiment, by providing a welding path 116 on the heat transfer plate 11 and disposed between the liquid inlet 111 and the liquid outlet 112, it is ensured that after the liquid enters the heat transfer plate 11 through the liquid inlet 111, it can flow fully inside the heat transfer plate 11 before flowing out of the heat transfer plate 11 through the liquid outlet 112. This prevents the liquid from entering the heat transfer plate 11 through the liquid inlet 111 and then immediately flowing out through the liquid outlet 112 near the liquid inlet 111, thereby optimizing the heat transfer effect.

[0044] In one embodiment, the welding path 116 includes a first welding path and a second welding path. The first welding path is arranged between the liquid inlet 111 and the liquid outlet 112, and the first welding path extends from the side of the heat transfer plate 11 in a direction away from the side; one end of the second welding path is connected to the first welding path and is perpendicular to the first welding path.

[0045] In this embodiment, two welding paths are provided. The first welding path is positioned between the liquid inlet 111 and the liquid outlet 112. One end of the first welding path is connected to the long side of the heat transfer plate 11 and extends perpendicularly away from the long side. This prevents liquid from immediately flowing out of the liquid outlet 112 near the liquid inlet 111 after entering the heat transfer plate 11 through the liquid inlet 111. The second welding path is connected to the first welding path at one end, perpendicular to the first welding path, and extends away from the first welding path at the other end. This ensures that the liquid within the heat transfer plate 11 flows along the predetermined path, further increasing the fluid flow and heat exchange efficiency within the heat transfer plate 11. Furthermore, the provision of two welding paths further ensures the structural strength and sealing of the heat transfer plate 11.

[0046] Furthermore, multiple welds are provided inside the heat transfer plate 11 to allow the liquid to circulate back and forth within the heat transfer plate 11, thereby fully flowing within the heat transfer plate 11 and improving heat exchange efficiency. The number of welds can be set according to actual needs, for example, 2, 3, 4, etc.

[0047] In one embodiment, a protective structure is provided above the heat transfer plate 11 to prevent the heat transfer plate 11 from being worn. Furthermore, the protective structure is made of stainless steel.

[0048] In this embodiment, by providing a protective structure above the heat transfer plate 11, scratches, wear, and damage to the heat transfer plate 11 caused by collision or friction between tiny particles, impurities, or other components and the heat transfer plate 11 can be avoided in actual use. The protective structure can act as a barrier and buffer, reducing damage to the heat transfer plate 11 caused by physical wear. The protective structure is made of stainless steel, and various protective structures suitable for the heat transfer plate 11 can be manufactured according to the shape, size, and installation requirements of the heat transfer plate 11. Stainless steel also has high strength and hardness and can withstand certain external impacts and pressures, ensuring that the protective structure is not easily deformed or damaged during operation and can stably perform its role in protecting the heat transfer plate 11. The protective structure can be a stainless steel plate; through processing methods such as stamping or welding, the stainless steel material is formed into a shape that matches the heat transfer plate 11, so that it can be better installed and fixed above the heat transfer plate 11.

[0049] In one embodiment, at least one opening is further provided on the other side of the housing 1 , and a transparent viewing mirror 3 is mounted on the opening.

[0050] In this embodiment, an opening is provided on the other side of the shell 1 relative to the water inlet pipe and the water outlet pipe, and a transparent sight glass 3 is installed on the opening, so that the situation of the material inside the plate-type heating device can be observed through the transparent sight glass 3, and whether there is a blockage problem during the soybean conditioning process can be understood in real time. This helps to promptly detect abnormal conditions inside the plate-type heating device and take corresponding measures to ensure the normal operation of the plate-type heating device. By providing multiple openings and arranging a transparent sight glass 3 on each opening, the situation inside the plate-type heating device can be observed from different angles to obtain more comprehensive information. Among them, the transparent sight glass 3 can be a transparent glass sight glass. The number of openings can also be set according to actual needs.

[0051] In one embodiment, a manhole 2 is further provided on the housing 1 , and the manhole 2 and the transparent sight glass 3 are arranged on the same side of the housing 1 .

[0052] In this embodiment, a manhole 2 is provided on the housing 1 to facilitate personnel to inspect, repair, and clean accumulated materials inside the plate-type heating device. The size of the manhole 2 can be set according to actual needs, and is not specifically limited as long as it meets the needs. The manhole 2 is provided on the same side of the housing 1 as the transparent window. When observing the internal operation of the plate-type heating device through the transparent window, when further inspection or operation is required, personnel can directly enter the plate-type heating device through the manhole 2 on the same side, thereby reducing the distance personnel need to move around the device and improving work efficiency.
