Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a fermentation tank cleaning device. Background Technology

[0002] In the production of soy sauce and other food condiments, their flavor primarily comes from fermentation. During fermentation, processed soybeans and other raw materials are typically placed in fermentation tanks, where microorganisms hydrolyze proteins. After fermentation, a large number of microorganisms, including beneficial bacteria and potentially other microorganisms, adhere to the inside of the fermentation tank. The tank also contains residues of soy sauce raw materials, fermentation products, and metabolic waste. To prevent these residues from mixing with new raw materials during the next fermentation and affecting the flavor of the new batch of soy sauce, it is necessary to clean the fermentation tank promptly. Current technology typically involves immersing the fermentation tank in a sufficient amount of cleaning solution to remove residual raw materials, followed by rinsing the inner wall of the tank with a high-pressure water gun to remove stubborn deposits. However, in actual cleaning, the high-pressure water gun usually only rotates at the top of the tank, potentially resulting in insufficient cleaning of the lower part of the tank. Furthermore, during fermentation, the nozzle is in communication with the inside of the tank, allowing microorganisms to enter the cleaning system through the nozzle, contaminating the system.

[0021] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0022] like Figures 1-5 As shown, this example provides a fermenter cleaning device, including: a tank body 100 and a cleaning assembly 200.

[0023] The cleaning assembly 200 includes a support shaft 201 passing through the center of the top of the tank 100. The support shaft 201 is vertically movable and rotatable around its own axis. A support frame 202 is provided at the lower end of the support shaft 201. Multiple spaced and detachably connected mounting blocks 203 are provided on the outer side of the support frame 202 along the circumferential direction. The mounting blocks 203 are hollow inside and have multiple nozzles 204 evenly distributed on their outer side for spraying cleaning liquid. The support shaft 201 has an inlet channel 205 extending through its upper end along its axial direction inside. The upper end of the inlet channel 205 is rotatably connected to the end of the inlet hose. Multiple guide channels 206 are provided on the inner side of the support frame 202 along the circumferential direction. The guide channels 206 are connected to the inlet channel 205 and the interior of the mounting blocks 203. The cleaning liquid is introduced into the inlet channel 205 through the inlet hose, flows into the interior of the mounting blocks 203 through the guide channels 206, and then sprays the cleaning liquid onto the inner wall of the fermenter through the nozzles 204.

[0024] Specifically, a driven gear 207 is sleeved on the support shaft 201. The driven gear 207 meshes with the first driving gear 208. The first driving gear 208 is mounted on the transmission shaft 209. The transmission shaft 209 is rotatably mounted on the top frame 210 and connected to the output end of the first power device. The first power device is mounted on the top frame 210, which is mounted on the top of the tank 100. During cleaning, the first power device drives the transmission shaft 209 to rotate. Under the meshing of the first driving gear 208 and the driven gear 207, the support shaft 201 starts to rotate, thereby uniformly spraying cleaning liquid onto the inner wall of the fermentation tank 100.

[0025] Specifically, in order to facilitate all-round cleaning of the inner wall of the fermenter 100, multiple keyways are arranged at intervals along the circumferential direction on the outer wall of the support shaft 201. The length direction of the keyways is parallel to the axis of the support shaft 201. Multiple key pins are arranged along the circumferential direction on the inner wall of the driven gear 207. The key pins slide in the keyways, so that the support shaft 201 can be driven to move up and down during rotation.

[0026] Specifically, the upper end of the support shaft 201 is rotatably mounted on the connecting rod 211. One end of the connecting rod 211 is provided with a vertically arranged rack 212. The rack 212 is slidably engaged with the top frame 210 and meshes with the second drive gear 213. The second drive gear 213 is mounted on the rotating shaft 214. The rotating shaft 214 is rotatably mounted on the top frame 210 and connected to the output end of the second power device. The second power device is mounted on the top frame 210. During the cleaning of the fermentation tank 100, the rotating shaft 214 is driven to rotate by the second power device. Under the meshing of the second drive gear 213 and the rack 212, the support shaft 201 will move up and down.

[0027] Specifically, the support frame 202 has multiple slots 215 along the circumferential direction on its outer side. The mounting block 203 is fitted into the slots 215 to limit the mounting block 203. The side wall of the mounting block 203 has a through hole 216. One end of the guide channel 206 extends through the slots 215 and is aligned with the through hole 216 to ensure that the cleaning fluid can flow smoothly through the guide channel 206 into the interior of the mounting block 203.

[0028] Specifically, the bottom surface of the support frame 202 is provided with multiple protruding rods 217 along the circumferential direction. A baffle 218 is fitted on the protruding rod 217. The baffle 218 is L-shaped, and when the mounting block 203 is removed from the support frame 202, its vertical section fits into the slot 215 to block the guide channel 206. A retaining ring 219 is provided at the lower end of the protruding rod 217, and a first spring 220 is fitted on the protruding rod 217. The two ends of the first spring 220 abut against the horizontal section of the baffle 218 and the retaining ring 219 respectively, and are always in a compressed state. Under the action of the first spring 220, the baffle 218 always has an upward tendency. When the mounting block 203 is installed in the slot 215, the lower end of the mounting block 203 abuts against the upper end of the baffle 218 and forces it to move downward. The first spring 220 is also further compressed until the through hole 216 is aligned with the guide channel 206. At this time, the mounting block 203 can be locked.

[0029] Specifically, to facilitate the installation and disassembly of the mounting block 203, a retaining plate 221 is provided on one side of the mounting block 203. When the mounting block 203 is located in the retaining groove 215, the bottom surface of the retaining plate 221 abuts against the top surface of the support frame 202. A retaining block 222 is provided on the top surface of the retaining plate 221. The top surface of the retaining block 222 away from the support shaft 201 is arc-shaped, and the other end is provided with a push rod 223. The push rod 223 passes through the protruding plate 224, which is installed on the support frame 202. A second spring is sleeved on the push rod 223. Spring 225, the two ends of the second spring 225 abut against the locking block 222 and the protruding plate 224 respectively, and are always in a compressed state. During the process of placing the mounting block 203 into the slot 215, the bottom edge of the locking plate 221 will contact the arc surface of the locking block 222, and force the locking block 222 to move. The second spring 225 is also further compressed until the locking plate 221 abuts against the top surface of the support frame 202. At this time, the locking block 222 is exactly above the locking plate 221, thus fixing the mounting block 203.

[0030] Specifically, to facilitate the installation and disassembly of the mounting block 203, an opening 101 is provided at the top of the tank body 100, and a connecting frame 301 is provided above the opening 101. The connecting frame 301 can be connected to the moving end of a vertical lifting mechanism, which drives the connecting frame 301 to move up and down. The vertical lifting mechanism is installed on the tank body 100. Two sliding rods 302 are provided in the connecting frame 301, and a pressure plate 303 and a clamping plate 304 are respectively fitted on the sliding rods 302. The pressure plate 303 is used to push the locking block 222. The top surface of the mounting block 203 is provided with a support plate 226, and the clamping plate 304 is L-shaped, with its horizontal section used to pass through the support plate 226. When installing the mounting block 203, the connecting frame 301 is placed at the opening 101 and moved downwards so that the pressure plate 303 contacts the arc-shaped surface of the locking block 222. This forces the locking block 222 to move away from the top surface of the locking plate 221. Then, the horizontal section of the clamping plate 304 passes through the support plate 226. After that, the connecting frame 301 is moved upward, and the mounting block 203 can be removed. At this time, the baffle 218 will block the guide channel 206 under the action of the first spring 220. When installing the mounting block 203, after the clamping plate 304 passes through the support plate 226, the connecting frame 301 is moved downward, so that the mounting block 203 is inserted into the locking groove 215. Then, the pressure plate 303 is moved along the axis of the slide rod 302, so that it is disengaged from the locking plate 221. Then, the locking block 222 will be positioned above the locking plate 221 under the action of the second spring 225, thus positioning the mounting block 203. After that, the clamping plate 304 is moved out of the support plate 226, and the connecting frame 301 is moved upward.

[0031] Since the above are merely preferred embodiments of this utility model and are not intended to limit this utility model, it is obvious that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
