Description

Technical Field

[0001] This utility model belongs to the technical field of microbial fermentation devices, and in particular relates to a concealed structure for the electrical control circuit of the support bracket of the liquid microbial fermentation tank body. Background Technology

[0002] Taking the traditional structure of liquid culture tanks as an example, its structure generally consists of: tank body, legs, tank jacket (some also have internal coils), jacket heating rod, filter, manhole, inoculation port, air supply pipe, sight glass, and microcomputer control box. Among them, when using a jacket heating rod as the culture medium insulation solution, all manufacturers place the heating rod directly inside the jacket of the tank. During normal cultivation, it heats the water in the jacket, thereby achieving the effect of heat preservation of the culture medium inside the tank through heat transfer, which is conducive to the growth and development of mycelium. It is used to control the temperature of the nutrient solution inside the fermenter, and different cultivation temperatures can be set according to different varieties.

[0003] Traditional heating rod installation methods involve inserting the rod directly into the fermentation tank's interlayer from the bottom to the top, leaving the power cord exposed. This makes it difficult to completely conceal the wiring, resulting in several disadvantages: 1. Exposed power cords are easily touched by people or objects during operation, leading to frequent breakage at the welded joint, causing leakage or damage to the wiring at the base of the heating rod, resulting in malfunction; 2. Leaking heating rods may cause injury; 3. Exposed power cords create a messy and disorganized appearance, lowering the overall equipment efficiency. 4. The thermocouple (nutrient solution sensor) is also fixed to the bottom end cap of the tank from the bottom. Its power cord is installed in the same way as the heating rod power cord. It can only be bundled together with the power cord and passed through the center of the round tube of the bracket (usually a stainless steel round tube) of the microcomputer control box to enter the microcomputer control box. Exposed electrical control circuits of liquid culture tanks are a common problem in the manufacturing of edible fungus fermentation tanks. The power cords of the heating rod and thermocouple (sensor) are exposed and cannot be completely sealed to achieve the degree of complete concealment of the circuits. Utility Model Content

[0004] In view of this, in order to solve the technical problems mentioned in the background art, this utility model proposes a concealed structure for the electrical control circuit of the liquid culture fermentation tank. This structure can completely conceal and safely handle the power lines of the heating rods and thermocouples (sensors). Not only do the power lines of the heating tubes and thermocouples disappear completely (concealed treatment), but it also eliminates the dangers and hidden dangers caused by the exposed power lines of the heating rods and thermocouples (sensors) on traditional liquid culture tanks due to the lack of a proper installation structure. The structure is ingenious and scientific, safe to use and aesthetically pleasing.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a concealed electrical control circuit structure for a liquid microbial fermentation tank, comprising a control box, a quick-connect connector, a thermocouple, a control box bracket, a heating rod jacket, and a heating rod. The upper end of the control box bracket supports the control box, and the lower end is connected to the heating rod. A quick-connect connector is installed on the side end, and a thermocouple is installed on the quick-connect connector. The thermocouple passes through the interlayer of the tank body and is fixed to the inner wall of the fermentation tank (upper middle part of the tank body). The part passing through the hollow interlayer needs to isolate the front end of the quick-connect connector. The inner tank body is provided with a pre-welded stainless steel threaded base. The threads of the thermocouple are wrapped with PTFE tape and twisted directly to achieve the effect of blocking contact with the water source.

[0006] Furthermore, the electrical control box bracket is a stainless steel round tube structure.

[0007] Furthermore, the control box is connected to the thermocouple and heating rod via power lines, all of which are located inside the steel pipe of the control box bracket.

[0008] Furthermore, the heating rod is protected by a heating rod jacket (the heating rod is inserted into the heating rod jacket from top to bottom), and the heating rod jacket is welded circumferentially to the tank body through the interlayer, so that the water inside the interlayer is in complete contact with the heating rod.

[0009] A liquid microbial fermentation tank includes a concealed structure for the electrical control circuitry of the liquid microbial fermentation tank.

[0010] Compared with the prior art, the beneficial effects of the concealed electrical control circuit structure of the liquid culture fermenter described in this utility model are:

[0011] This invention relates to a structure that can completely conceal and safely handle the power lines of the heating rod and thermocouple (sensor). Not only do the power lines of the heating tube and thermocouple completely disappear (concealment treatment), but it also eliminates the dangers and hidden dangers caused by the exposed power lines of the heating rod and thermocouple (sensor) on traditional liquid culture tanks due to the lack of a proper installation structure. The structure is ingenious and scientific, safe to use and aesthetically pleasing. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present utility model can be combined with each other, and the described embodiments are only some embodiments of the present utility model, not all embodiments.

[0021] See Figure 1-6 This embodiment describes a concealed electrical control circuit structure for a liquid microbial fermentation tank, comprising a control box 1, a quick-connect connector 2, a thermocouple 3, a control box bracket 4, a heating rod jacket 5, and a heating rod 6. The upper end of the control box bracket 4 supports the control box 1, and the lower end connects to the heating rod 6. A quick-connect connector 2 is installed on the side end, and a thermocouple 3 is mounted on the quick-connect connector 2. The thermocouple 3 passes through the interlayer of the tank body 9 and is fixed to the inner wall 17 (upper middle part of the tank body). The part passing through the hollow interlayer needs to isolate the front end of the quick-connect connector 2. The inner tank body is provided with a pre-welded stainless steel threaded base. The threads of the thermocouple 3 are wrapped with PTFE tape and tightened directly, thereby achieving the effect of blocking contact with the water source.

[0022] The electrical control box bracket 4 is a stainless steel round tube structure.

[0023] The control box 1 is connected to the thermocouple 3 and the heating rod 6 via a power cord 15, and the power cord 15 is located inside the steel pipe of the control box bracket 4.

[0024] The heating rod 6 is protected by the heating rod jacket 5. The heating rod jacket 5 is welded to the tank body in the circumferential direction, which is connected to the inside of the tank body interlayer. The water inside the interlayer is in complete contact with the heating rod 6.

[0025] The heating rod 6 is inserted into the heating rod jacket 5 from top to bottom.

[0026] Specifically, the heating rod 6 is mounted on the threaded base 18 of the heating rod and connected by threads. The threaded base 18 of the heating rod is welded to the upper part of the outer sleeve 5 of the heating rod.

[0027] A liquid microbial fermentation tank includes the aforementioned concealed structure for the electrical control circuitry of a liquid microbial fermentation tank.

[0028] The working principle of the concealed electrical control circuit structure of the liquid culture fermenter described in this utility model is as follows:

[0029] This utility model adopts an inverted installation scheme for the heating rod 6, which passes through the interlayer of the tank body 9 with the thermocouple 3 and is fixed to the inner wall of the fermentation tank. The part passing through the interlayer is connected with the entire control box bracket 4 by using a quick-connect connector 2, thus blocking contact with the water source. This installation structure allows the power lines 15 of the heating rod 6 and the thermocouple (sensor) 3 to be naturally threaded into the control box bracket 4 and the rear support tube 2 without bending or folding. Finally, the power lines enter the microcomputer control box 1 through the through hole of the bottom support plate supporting the microcomputer control box 1, thereby completely hiding the wiring of the heating rod and the thermocouple.

[0030] Meanwhile, during the welding of the tank body 9, when the heating rod outer jacket 5 is welded to the interior of the interlayer in the circumferential direction, an opening is made in the interlayer of the tank body according to the specifications of the open side of the heating rod outer jacket 5, and then it is welded closed. In this way, the water inside the interlayer will be in complete contact with the heating rod 6, thereby achieving the effect of automatic heating and heat preservation.

[0031] After being manufactured and assembled through the above process, an invisible structure is formed, in which the circuitry appears completely concealed on the surface, making it both safe and aesthetically pleasing.

[0032] This structure is only for the purpose of concealing the circuit of the heating rod 6 and thermocouple (sensor) 3 in this utility model. It does not mean that this utility model must be in accordance with the structure shown in the figure to be effective. The principle and structure of the power line of the heating rod 6 and thermocouple (sensor) 3 designed in this utility model can be applied to all types of edible fungi fermentation tanks (including other industrial cultivation types) that use sandwich heating and insulation and conventional thermocouple (sensor) 3 structures.

[0033] The embodiments of the present invention disclosed above are merely illustrative of the present invention. The embodiments do not exhaustively describe all details, nor do they limit the present invention to the specific implementations described. Many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present invention, thereby enabling those skilled in the art to better understand and utilize the present invention.
