Abstract
Description
Technical Field
[0001] This utility model relates to the field of biochemical technology, and more specifically to a heating device for biochemical applications. Background Technology
[0002] In biochemical experiments and small-scale production processes, the heat treatment of high-viscosity materials, such as cell culture media, enzymatic hydrolysates, and biocolloids, often faces technical challenges such as low heat transfer efficiency and uneven temperature distribution. Traditional stirring-type heating devices mainly have the following drawbacks:
[0003] Existing equipment relies on mechanical agitators to generate shear force to drive material flow. However, when the material viscosity is high, the agitator is unable to push the material to move as a whole, resulting in stubborn dead zones forming on the tank wall and bottom, which seriously damages protein activity or reaction uniformity.
[0004] For heating high-viscosity fluids, gravity drive is required to enhance the flow. However, conventional reaction vessels are fixed structures and cannot change the direction of force on the material by tilting. Some tiltable equipment uses simple rotating shaft support, and the vessel is prone to shaking and displacement during the tilting process, which can lead to seal failure or material splashing. Utility Model Content

[0019] The device includes a horizontal rod 403 and a heating tank 101. Arc-shaped slides A401 and B402 are fixedly connected to the horizontal rod 403. Two auxiliary rods 103 are fixedly connected to the heating tank 101, and are respectively inserted into the arc-shaped slides A401 and B402. The heating tank 101 is rotatably connected to the horizontal rod 403. A connecting disc 201 is connected to the heating tank 101, and a stirring rod 203 is fixedly connected to the connecting disc 201. The heating tank 101 is equipped with a heat source, which is an electric heating plate or a heat exchanger. Two shells that can be joined together to form a complete stirring paddle are fitted onto the stirring rod 203.
[0020] The biochemical raw material to be heated is added into the heating tank 101, and then the connecting disc 201 is rotated on the heating tank 101. The stirring rod 203 is used to continuously stir the raw material inside the heating tank 101, and the heat source is turned on to achieve a uniform heating effect on the biochemical raw material.
[0021] During this process, the heating tank 101 can be rotated on the horizontal rod 403, thereby causing the heating tank 101 to flip at a certain angle. This allows gravity to guide the movement of viscous biochemical raw materials inside the heating tank 101, avoiding situations where the material has a high viscosity and cannot be moved by stirring alone, resulting in dead zones in the material and affecting the subsequent heating effect. In other words, this equipment can force the material to flow, prevent material sedimentation, and eliminate heating dead zones.
[0022] The arrangement of the arc-shaped slide rails A401 and B402 and the two auxiliary rods 103 enables the arc-shaped slide rails A401 and B402 to support the two auxiliary rods 103 during the rotation of the heating tank 101, thereby ensuring the stability of the heating tank 101 during the rotation process. This avoids instability or vibration caused by material flow during the actual rotation of the heating tank 101, making it suitable for smaller production or experimental scenarios.
[0023] Two of each of the arc-shaped slide rails A401, B402, and transverse rods 403 are symmetrically provided. Four of each of the auxiliary rods 103 are symmetrically provided. An auxiliary rod 103 is inserted into each arc-shaped slide rail A401, and an auxiliary rod 103 is also inserted into each arc-shaped slide rail B402.
[0024] Two symmetrically arranged arc-shaped slide rails A401 and B402 and a transverse rod 403 can provide stable support for both sides of the heating tank 101, further ensuring the stability of the heating tank 101 during rotation and preventing equipment displacement caused by sudden material flow during the rotation of the heating tank 101.
[0025] The connecting disc 201 is detachably connected to the heating tank 101, and the stirring rod 203 is provided with a bottom plate 204, which has multiple connecting threaded holes.
[0026] The two shells that are joined together to form a complete stirring paddle are connected to the stirring rod 203 by screwing bolts into the bottom plate 204. Then, the connecting disc 201 is fixed to the heating tank 101, so that the stirring rod 203 can be rotated to drive the stirring paddle to rotate and achieve the stirring effect on the material.
[0027] It also includes a first motor 202 fixedly connected to the connecting disc 201, and the output shaft of the first motor 202 is fixedly connected to the stirring rod 203.
[0028] By starting the first motor 202, the output shaft of the first motor 202 drives the stirring rod 203 to rotate, and the stirring rod 203 continues to rotate to complete the subsequent stirring effect on the material.
[0029] It also includes a feed inlet 102 located on the heating tank 101.
[0030] The staff feeds the material to be heated into the feed inlet 102 by adding the material into the feed inlet 102, so that the material is stored in the heating tank 101 for subsequent heating operations. After the material is added, an arc-shaped cover is sealed on the feed inlet 102 by tightening the bolts to complete the shielding.
[0031] It also includes a discharge port 105 located on the heating tank 101.
[0032] After heating is complete, the heating tank 101 can be rotated to tilt so that the material is discharged from the outlet 105 to complete the material discharge operation. When the outlet 105 is not needed, a rectangular plate can be used to cover the outlet 105 by tightening the bolts to prevent leakage.
[0033] The heating tank 101 has multiple connection holes 104.
[0034] The heating element or heat exchanger is connected to the outside of the heating tank 101 by screwing bolts into multiple connection holes 104, thereby improving the heat source guarantee for subsequent heating operations.
[0035] A motor base 303 is connected to the transverse rod 403, a second motor 302 is fixedly connected to the motor base 303, and a drive plate 301 is fixedly connected to the output shaft of the second motor 302.
[0036] When it is necessary to rotate the heating tank 101, the output shaft of the second motor 302 is rotated, which in turn drives the drive plate 301 to rotate, thereby driving the heating tank 101 to rotate and complete the subsequent efficient and uniform heating effect.
[0037] The drive plate 301 is detachably connected to the heating tank 101 by bolts, and the motor base 303 is detachably connected to the transverse rod 403 by bolts.
[0038] When the second motor 302, originally fixed to one side of the transverse bar 403, malfunctions and cannot perform subsequent drive operations normally, the original motor mount 303 and drive plate 301 can be removed by loosening the bolts, and then another spare motor mount 303 can be installed. The second motor 302 and drive plate 301 are then structurally connected to the other side of the transverse bar 403, reducing operation and maintenance intervals and bringing convenience to actual use.
[0039] It also includes a support frame 404, on the upper side of which two horizontal rods 403 are fixed.
[0040] The support frame 404 can support the two horizontal bars 403 to a certain height, thereby providing sufficient space for the subsequent rotation of the heating tank 101.
