Description

Technical Field

[0001] The utility model relates to the technical field of biopharmaceuticals, in particular to a vertical tail gas heating device suitable for a bioreactor. Background Art

[0002] A reactor is a container that provides a living environment and space for cells, microorganisms, etc. It is often a confined space. Materials entering and leaving the reactor must be filtered and controlled to avoid contamination of the reactants inside. During biological reactions, gases are discharged from the reaction vessel. These gases are often moist and contain water vapor. Since the temperature inside the reactor is higher than the ambient temperature, the gases will condense in the filter on the exhaust line, causing the filter to clog and the exhaust process to be forced to terminate. To solve the problem of exhaust filter clogging caused by condensed exhaust, the filter can be heated to prevent water vapor from condensing inside the filter.

[0003] In the prior art CN219091471U, a heating device is provided. However, this heating device requires an additional bracket for suspension, which occupies the upper space of the reactor. Moreover, since it is suspended, a long pipeline is required between the filter and the reaction vessel, which will cause water vapor to condense on the pipeline and flow back into the reactor. Utility Model Content

[0004] In view of the above situation, it is necessary to provide a vertical exhaust gas heating device suitable for bioreactors to address the problem that the exhaust gas filter of the reactor is blocked by condensed exhaust gas in the prior art.

[0005] A vertical exhaust gas heating device suitable for a bioreactor comprises two outer shell bodies, two heating components and a terminal assembly, the two outer shell bodies are arranged opposite to each other, one side of the two outer shell bodies is hingedly connected, and the other side of the two outer shell bodies is movably connected, the upper end and the lower end of the outer shell body are both provided with a first half-hole, the first half-hole is used to accommodate a pipeline, the outer shell body is a hollow structure, the two heating components are respectively arranged in the two hollow structures, the heating component comprises a heating cover and a heating block, the heating cover is fixedly connected to the outer shell body, the heating block is arranged between the heating cover and the outer shell body, the heating block is fixedly connected to the heating cover, the heating cover and the outer shell body form a gap, the heating block and the outer shell body form a gap, the upper end and the lower end of the heating cover are both provided with a second half-hole, the second half-hole is used to accommodate a filter, the terminal assembly is fixedly provided on the inner wall of the two outer shell bodies, the terminal assembly is used to electrically connect the two heating blocks, and a bracket is provided at the lower end of the outer shell body.

The shell body 1 is a hollow structure 12, and the two heating components 2 are respectively arranged in the two hollow structures 12.

[0027] Specifically, such as Figure 1 and Figure 2 As shown, the inner wall of one shell body 1 is provided with a plurality of first magnetic blocks 14, and the inner wall of the other shell body 1 is provided with a plurality of second magnetic blocks 15.

[0028] Specifically, such as Figures 1 to 5As shown, the terminal assembly 3 is fixed to the inner wall of the two shell bodies 1 and is arranged with its back to the hinge 16. The terminal assembly 3 includes a male terminal 31 and a female terminal 32. The male terminal 31 is arranged adjacent to the female terminal 32. The two sides of the male terminal 31 are respectively provided with a first terminal 311 and a protrusion 312. The first terminal 311 is electrically connected to the external cable, one of the heating blocks 22 and the protrusion 312. The two sides of the female terminal 32 are respectively provided with a second terminal 321 and a recess 322. The female terminal 32 is provided with a side facing the protrusion 312.

The position and size of the convex portion 312 and the concave portion 322 are adapted to each other. The shell body 1 on which the male terminal 31 is provided is provided with a lead hole 13. When the shell body 1 is closed, the convex portion 312 abuts against the concave portion 322. After the external cable is energized, the first terminal 311 and the second terminal 321 are respectively connected to the external power supply, so that the two heating blocks 22 are heated.

[0029] Specifically, such as Figures 1 to 3 As shown, the heating assembly 2 includes a heating cover 21 and a heating block 22. The inner wall of the outer shell body 1 is provided with a plurality of bosses 16. The boss 16 is located on the side of the heating block 22 away from the heating cover 21. The length of the boss 16 is greater than the thickness of the heating block 22. The heating cover 21 is fixedly connected to the boss 16. The heating block 22 is arranged between the heating cover 21 and the outer shell body 1. The heating block 22 is fixedly connected to the heating cover 21. A gap is formed between the heating cover 21 and the outer shell body 1. A gap is formed between the heating block 22 and the outer shell body 1. A second half-hole 211 is provided at the upper and lower ends of the heating cover 21. The second half-hole 211 is used to accommodate a filter. The heat generated by the heating block 22 will not be conducted to the outer shell body 1, and the heat generated by the heating cover 21 through the heating block 22 will not be conducted to the outer shell body 1, thereby ensuring heating efficiency and preventing burns from occurring when moving the outer shell body 1.

[0031] Specifically, such as Figure 1 As shown, a bracket 4 is provided at the lower end of the shell body 1. The bottom of the bracket 4 is arc-shaped 41. The two arcs 41 enclose a receiving space for accommodating pipelines. The center of the arc 41 faces the inner side of the bracket 4, providing better support for the bracket 4.

[0032] The implementation process of this utility model is:

[0033] The two outer shell bodies 1 are in an open state, and the upper and lower ends of the filter are placed in the second half-hole 211 of one of the heating covers 21.

At this time, the convex portion 312 abuts against the concave portion 322, so that the second terminal 321 is connected to the external power supply, and then the two heating blocks 22 start to heat up, and the heat is transferred to the two heating covers 21. The heat of the heating hoods 21 is then conducted to the filter. Since the filter and the pipe loops connected at both ends of the filter are directly connected, the bracket 4 is arranged under the outer shell body 1, and the two arcs 41 enclose a accommodating space. The accommodating space is used to accommodate the pipeline, and there will be no pipeline winding. The water vapor on the pipeline will not condense and flow back into the reactor, thereby preventing the exhaust filter of the reactor from having exhaust blockage problems. The two heating hoods 21 form a gap with the outer shell body 1, and the two heating blocks 22 form a gap with the outer shell body 1. The heat generated by the heating block 22 will not be conducted to the outer shell body 1, and the heat generated by the heating hood 21 through the heating block 22 will not be conducted to the outer shell body 1, thereby ensuring the heating efficiency and preventing the moving outer shell body 1 from being scalded. The center of the arc 41 faces the inner side of the bracket 4, providing better support for the bracket 4.
