Description

Technical Field

[0001] This utility model relates to the field of bio-fermentation technology, specifically a constant-temperature bio-fermentation device. Background Technology

[0002] Bio-fermentation engineering is an important component of bioengineering. Fermentation engineering originated from home or workshop-style fermentation production, later borrowed from chemical engineering to achieve industrial production, and finally returned to its roots by studying, designing and guiding industrial fermentation production with microbial life activities as the center, thus entering the ranks of bioengineering.

[0003] Biological fermentation is a complex process. Different environmental factors such as temperature, humidity, and carbon dioxide concentration can affect the fermentation speed. Therefore, it is necessary to regularly sample and observe the fermentation process and adjust the fermentation culture parameters in a timely manner. However, directly opening the fermentation tank for sampling will allow external air and microorganisms to enter the fermentation tank, thereby changing the environment inside the fermentation tank and altering the culture conditions before and after sampling, leading to inaccurate test results.

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0037] Please see Figure 1-5 As shown, this utility model is a constant-temperature biological fermentation device, comprising:

[0038] A constant temperature fermentation tank 100 has three sampling holes 150 on its side wall;

[0039] The sampling mechanism 200 has three parts connected to three sampling holes 150 respectively. The sampling mechanism 200 includes an insertion tube 210, a sampling tube 220, a handle 230, and a spring-loaded component 240.

[0040] The insertion tube 210 is slidably connected within the sampling port 150. A fixing plate 211 is fixed to the end of the insertion tube 210. The sampling tube 220 is slidably connected within the insertion tube 210. A circular plate 221 is fixedly connected to the end of the sampling tube 220. A handle 230 is fixedly connected to the surface of the circular plate 221. The two ends of the spring-loaded assembly 240 are fixedly connected to the surface of the fixing plate 211 and the bottom surface of the circular plate 221, respectively. When sampling and observation are required, the handle 230 is pushed inward, causing the circular plate 221 to move. The sampling tube 220 is moved inward, causing it to slide within the insertion tube 210. At this time, the rebound component 240 is compressed, and the sampling tube 220 moves into the constant temperature fermentation tank 100. After inserting the biological raw material in the constant temperature fermentation tank 100 into the sampling tube 220, the handle 230 is released. The rebound component 240 rebounds, causing the circular plate 221 to move outward. The circular plate 221 causes the sampling tube 220 to slide outward. It is no longer necessary to open the constant temperature fermentation tank during sampling, thus preventing outside air from entering the tank during sampling.

[0041] The rebound assembly 240 includes a telescopic tube 241 and a first spring 242;

[0042] The telescopic tube 241 is fixedly connected at both ends to the surface of the fixed plate 211 and the bottom surface of the circular plate 221, respectively. The telescopic tube 241 passes through the first spring 242, which is fixedly connected at both ends to the surface of the fixed plate 211 and the bottom surface of the circular plate 221, respectively. When the circular plate 221 moves, it causes the telescopic tube 241 to shorten and the first spring 242 to compress. The rebound of the first spring 242 can push the circular plate 221 to move and stretch the telescopic tube 241.

[0043] A feed inlet 120 is fixedly installed on the top surface of a constant temperature fermentation tank 100. A support frame 110 and a discharge port 130 are fixedly connected to the bottom surface of the constant temperature fermentation tank 100. A discharge valve 140 is fixedly connected to the bottom of the discharge port 130. A motor 310 is fixedly connected to the top surface of the constant temperature fermentation tank 100. A driven shaft 320 is fixedly connected to the power output end of the motor 310. A stirring rod 330 is fixedly connected to the side wall of the driven shaft 320. Fermentation biological raw materials are added through the feed inlet 120. The motor 310 drives the driven shaft 320 to rotate, which in turn drives the stirring rod 330 to rotate. The rotation of the stirring rod 330 stirs the biological raw materials in the constant temperature fermentation tank 100, making the fermentation and heating uniform. After fermentation is completed, the discharge valve 140 is opened to discharge the biological raw materials from the discharge port 130.

[0044] The sampling mechanism 200 also includes a fixing component 250, which includes a protruding post 251, a square hole 252, an inclined post 254, and a tie post 256.

[0045] The protruding post 251 is fixed to the side of the sampling hole 150. The square hole 252 is opened in the protruding post 251. The inclined post 254 is slidably connected in the square hole 252. One end of the pull post 256 is fixed to the surface of the inclined post 254. When the fixing plate 211 contacts the inclined surface of the inclined post 254, the inclined post 254 is pushed into the square hole 252 through the inclined surface. The inclined post 254 drives the pull post 256 to move upward. When the fixing plate 211 and the inclined surface of the inclined post 254 are no longer in contact, the inclined post 254 slides down and the straight surface of the inclined post 254 contacts the fixing plate 211, fixing the fixing plate 211, thereby fixing the sampling mechanism 200 in the sampling hole 150.

[0046] The fixing assembly 250 also includes a first limiting plate 253, a second limiting plate 255, a top plate 257, and a second spring 258;

[0047] The second limiting plate 255 is set around the upper end of the inclined column 254, and the first limiting plate 253 is set around the opening of the square hole 252 to prevent the inclined column 254 from popping out of the square hole 252. The second spring 258 is fixedly set in the middle of the square hole 252. The pull column 256 passes through the second spring 258, the top plate 257 and the top surface of the protruding column 251. The two ends of the second spring 258 are fixedly connected to the surface of the inclined column 254 and the bottom surface of the top plate 257, respectively. When the inclined column 254 rises, it compresses the second spring 258. When the fixed plate 211 disengages from the inclined surface of the inclined column 254, the second spring 258 rebounds and drives the inclined column 254 to slide down.

[0048] Working principle: After adding biological raw materials to the constant temperature fermentation tank 100 and fermenting for a period of time, when sampling and observation are required, push the handle 230 inward. The handle 230 moves the circular plate 221, which in turn moves the sampling tube 220 inward, causing it to slide within the insertion tube 210. At this time, the movement of the circular plate 221 causes the telescopic tube 241 to shorten, while simultaneously compressing the first spring 242. The sampling tube 220 moves into the constant temperature fermentation tank 100. After inserting the biological raw materials from the constant temperature fermentation tank 100 into the sampling tube 220, release the handle 230. The first spring 242 rebounds, pushing the circular plate 221 to move and extending the telescopic tube 241. The circular plate 221 then causes the sampling tube 220 to slide outward. Pulling the pull column 256 outward causes the inclined column 254 to move into the square hole 252. The movement of the square hole 252 compresses the second spring 258. When the inclined column 254 is fully inserted into the square hole 252, it moves outward. Pulling the handle 230 causes the sampling tube 220, the rebound component 240, and the insertion tube 210 to be pulled out of the sampling hole 150. After the biological raw material is poured out of the sampling tube 220, the insertion tube 210 is aligned with the sampling hole 150 and inserted. When the fixing plate 211 contacts the inclined surface of the inclined column 254, the inclined surface pushes the inclined column 254 into the square hole 252. The inclined column 254 drives the pull column 256 to move upward and compresses the second spring 258. When the fixing plate 211 and the inclined surface of the inclined column 254 are no longer in contact, the second spring 258 rebounds and causes the inclined column 254 to slide down so that the inclined column 254 contacts the fixing plate 211 directly, fixing the fixing plate 211. This fixes the sampling mechanism 200 in the sampling hole 150. It is no longer necessary to open the constant temperature fermentation tank during sampling, which prevents outside air from entering the tank during sampling. The fermentation status of the biological raw material in different layers of the tank can also be observed through the sampling mechanism at different positions.

[0049] Please see Figure 1-5 As shown, this embodiment, based on the above embodiment, further includes:

[0050] The sampling hole 150 has a deep hole 151 inside. The sampling mechanism 200 also includes a shielding component 260, which includes a baffle 261 and a rotating shaft 262.

[0051] The rotating shaft 262 is rotatably connected to the upper end of the side wall of the deep hole 151, and the side of the baffle 261 is rotatably connected to the rotating shaft 262. The diameter of the baffle 261 is larger than the diameter of the sampling hole 150.

[0052] The shielding assembly 260 also includes a first connecting post 263, a first rotating plate 264, an extension plate 265, a second connecting post 266, a second rotating plate 267, and a third spring 268;

[0053] The first connecting post 263 is fixedly connected to the surface of the baffle 261. The first rotating plate 264 is rotatably connected to the side wall of the first connecting post 263. The extension plate 265 is fixedly set on the upper side of the opening of the deep hole 151. The second connecting post 266 is fixedly connected to the inner wall of the extension plate 265. The second rotating plate 267 is rotatably connected to the side wall of the extension plate 265. The two ends of the third spring 268 are respectively fixedly connected to the surface of the first rotating plate 264 and the surface of the second connecting post 266. When the sampling tube 220 is inserted inward, it pushes the baffle 261 to flip. The flipping of the baffle 261 drives the first connecting post 263 to rotate while compressing the third spring 268. When the third spring 268 is compressed, the second connecting post 266 rotates at the same time. When the sampling tube 220 is pulled out of the sampling hole 150, the first connecting post 263 rotates in the opposite direction and is pressed tightly against the bottom of the deep hole 151 when the third spring 268 rebounds, which increases the sealing and prevents the baffle 261 from being easily opened.

[0054] Working principle: When the sampling tube 220 is inserted inward, it pushes the baffle 261 to flip. The flipping of the baffle 261 drives the first connecting column 263 to rotate and compresses the third spring 268. When the third spring 268 is compressed, the second connecting column 266 rotates at the same time. When the sampling tube 220 is pulled out of the sampling hole 150, the third spring 268 rebounds and the first connecting column 263 rotates in the opposite direction and presses tightly against the bottom of the deep hole 151, which increases the airtightness and prevents the baffle 261 from being easily opened. This also prevents outside air from entering the tank through the sampling hole 150 when the sampling mechanism 200 is pulled out.
