Description

Technical Field

[0001] The present application relates to the technical field of fermentation equipment, and in particular to a symmetrical cantilever auger-type solid-state fermentation tray. Background Art

[0002] At present, automated industrial-grade solid-state fermentation equipment has not been widely used. Most companies use bag fermentation in fermentation rooms or fermentation tanks, wooden boxes and fermentation trays for fermentation production.

[0003] Most fermentation trays are used to transport and discharge materials by laying a circular track on the edge of the fermentation tray, installing a rack-type lifting mechanism in the center of the fermentation tray, and using the lifting mechanism to control the suspended auger to move up and down and rotate along the circular track to load and unload materials. However, during use, laying the circular track is difficult, and high strength requirements are placed on the fermentation tray shell structure. In addition, the rigidity of the auger suspension structure on one side is poor. When unloading sticky materials after fermentation, the auger will shake when it runs to the bottom, causing the fermentation tray to shake as a whole. At the same time, the auger has to rotate a full circle in the fermentation tray to clean a layer of material, and the efficiency of transporting materials is slow.

[0004] Anaerobic fermentation is one of the many fermentation processes. Anaerobic fermentation requires an oxygen-free and closed environment. When using a fermentation tray for anaerobic fermentation, the cylinder and cylinder cover that hold the material will wear and deform after long-term use. In order to ensure the sealing effect of the cylinder and the cylinder cover, a sealing gasket or rubber ring with enhanced sealing performance is usually installed at the connection position. The sealing gasket or rubber ring is used to enhance the sealing performance between the cylinder and the cylinder cover, but the sealing gasket or rubber ring is usually fixedly installed on the outside of the cylinder and the cylinder cover. When the staff cleans and maintains the cylinder and the cylinder cover, the exposed sealing gasket or rubber ring is easily damaged, resulting in a short service life. At the same time, the exposed sealing gasket or rubber ring is easy to stick to the material, resulting in poor sealing effect. Summary of the Invention

[0008] By adopting the above technical solution, the cylinder cover is opened and the material is put into the cylinder body. After the material is loaded, the cylinder cover is closed, and the cylinder cover will contact and press the first slider extending out of the fixed frame. The movement of the first slider drives the first slide bar to move, thereby driving the turntable to rotate. The rotation of the turntable controls the movement of the second slide bar to push the first sealing sleeve out of the fixed frame. The contact and resistance between the first sealing sleeve and the cylinder cover will increase the sealing performance between the cylinder body and the cylinder cover, reduce the possibility of gaps between the cylinder body and the cylinder cover, and ensure that during anaerobic fermentation, the outside air will not enter the cylinder body through the gap between the cylinder cover and the cylinder body, providing a closed environment for the fermentation of the material. The first sealing sleeve When not in use, it stays in the fixed frame, which reduces the exposure time of the first sealing sleeve and the possibility of wear and tear on the first sealing sleeve when the staff cleans and maintains the cylinder body and the cylinder cover, thereby achieving the protection effect of the sealing sleeve and enhancing the service life of the sealing sleeve. When the cylinder cover is closed on the cylinder body, the cylinder cover presses the first slider and the turntable controls the second slider to quickly push the first sealing sleeve out of the fixed frame for rapid sealing. The implementation method is simple and efficient. After the fermentation is completed, the fresh air system removes the odor generated by the fermentation in the cylinder. When the cylinder cover is opened, the discharging device quickly transports the fermented materials, which is conducive to enhancing the convenience of the solid-state fermentation tray during use.

After the third sealing sleeve is pushed out of the second receiving groove, it will abut against the side wall of the other semi-annular cylinder cover, which is conducive to enhancing the sealing performance of the joint position of the two semi-annular cylinder covers, preventing the formation of a gap at the joint position when the two semi-annular cylinder covers are joined, and preventing air from entering through the gap and affecting the anaerobic fermentation process. When the third slide bar moves toward the outside of the cylinder cover, the movable bar pulls the fixed plate back to its position through the third protruding bar, and the fixed plate drives the fourth slide bar to move so that the third sealing sleeve is retracted into the second receiving groove, reducing the time the third sealing sleeve is exposed to the outside of the cylinder cover, protecting the third sealing sleeve, and promoting the service life of the third sealing sleeve.

[0046] Open the cylinder cover 21, and the feeding device 3 feeds the material into the cylinder 2. The discharging device 4 controls the filling of the material in the cylinder 2 so that the material can be evenly filled in the cylinder 2. After the material filling is completed, close the cylinder cover 21 to ferment the material. After the fermentation is completed, the fresh air system 5 is used to extract the fermentation odor gas in the cylinder 2, and then open the cylinder cover 21. The discharging device 4 controls the material to send the material out of the cylinder 2, so as to quickly complete a round of material fermentation, which is beneficial to improve the efficiency of the solid-state fermentation tray during use.

[0047] Connected to the barrel cover 21 is an opening and closing mechanism 22 that controls the opening and closing of the barrel cover 21. This mechanism includes a first swing arm 221 and a second swing arm 222, which are hingedly connected to the barrel cover 21. The first and second swing arms 221, 222 are of equal length and arranged parallel to each other. The ends of the first and second swing arms 221, 222, facing away from the barrel cover 21, are hingedly connected to a fixed rod 223, which is also used to securely suspend the barrel cover 21.

The first guide block 243 is arranged on the side of the partition 242 close to the cylinder 2, and a first sliding block 243 is slidably connected to the first guide block 243. Rod 244, the first slide rod 244 is vertically arranged through the first guide block 243, the first slide rod 244 is fixedly installed with a first slider 245 on the top, the first slider 245 extends out of the fixed frame 241, and one end of the first slider 245 extending out of the fixed frame 241 is set to a hemispherical shape, and a first spring 246 is sleeved on the first slide rod 244, one end of the first spring 246 is fixedly connected to the first guide block 243, and the other end is fixedly connected to the first slider 245, and the bottom end of the first slide rod 244 is fixedly installed with a first guide rail 2441, and the first guide rail 2441 is horizontally arranged.

[0050] A turntable 2472 is rotatably mounted on the partition 242. The turntable 2472 is disposed below the first guide block 243. A first protruding rod 2473 and a second protruding rod 2474 are fixedly mounted on the turntable 2472. The first protruding rod 2473 is located above the second protruding rod 2474. The first protruding rod 2473 is slidably connected to the first guide rail 2441. In this embodiment, one first slider 245 corresponds to one turntable 2472 as a group. A total of six groups of first sliders 245 and turntables 2472 are disposed on the fixed frame 241. Each group of first sliders 245 and turntables 2472 is disposed on the fixed frame 241 at equal angles and circumferences. Figure 3 and Figure 4 Only one set of the first slider 245 and the turntable 2472 is shown.

[0051] A second guide block 251 is fixedly mounted on the fixed frame 241. A second slide bar 252 is slidably mounted on the second guide block 251. The second slide bar 252 passes through the second guide block 251 and is vertically arranged. A second guide rail 253 is fixedly mounted on the bottom end of the second slide bar 252. A second protruding rod 2474 is slidably connected to the second guide rail 253. A first mounting plate 254 is fixedly mounted on the end of the second slide bar 252 away from the second guide rail 253. A first sealing sleeve 255 is fixedly mounted on the first mounting plate 254. The first sealing sleeve 255 is disposed within the fixed frame 241.

[0052] Reference Figure 2 、 Figure 3 and Figure 4 When the cylinder cover 21 moves toward the cylinder body 2 and closes on the cylinder body 2, the cylinder cover 21 will first contact the first slider 245 before contacting the cylinder body 2. The cylinder cover 21 will press the first slider 245 downward and the first slide bar 244 will slide on the first guide block 243. When the first slider 245 and the first slide bar 244 slide downward, they will compress the first spring 246. The first slide bar 244 will drive the first guide rail 2441 to move downward. The first slide bar 244 pushes the first protruding rod 2473 to slide in the first guide rail 2441 and causes the turntable 2472 to rotate. When the first protruding rod 2473 moves downward and the turntable 2472 rotates It will drive the second protruding rod 2474 to move upward, and the second protruding rod 2474 slides in the second guide rail 253 and pushes the second guide rail 253 to move upward. The second guide rail 253 drives the second slide bar 252 to move upward, and the second slide bar 252 pushes the first sealing sleeve 255 out of the fixed frame 241 and contacts the cylinder cover 21. The first sealing sleeve 255 is a soft rubber sleeve. When pressed on the cylinder cover 21, it will increase the sealing performance between the cylinder body 2 and the cylinder cover 21, ensuring that during anaerobic fermentation, outside air will not enter the cylinder body 2 through the gap between the cylinder cover 21 and the cylinder body 2, providing a closed environment for the fermentation of the material.

[0053] When the cylinder cover 21 leaves the cylinder body 2, the first slider 245 loses the pressure of the cylinder cover 21, and the first spring 246 supports the first slider 245 so that the first slider 245 extends out of the fixed frame 241 again. The first slider 245 pulls the first protruding rod 2473 to move upward, so that the turntable 2472 rotates. The second protruding rod 2474 moves downward and pulls the second sliding rod 252 to move downward. The second sliding rod 252 drives the first sealing sleeve 255 to be retracted into the fixed frame 241. When the first sealing sleeve 255 is retracted, it will pass through the brush at the outlet of the fixed frame 241 to remove In addition to the materials contaminated on the first sealing sleeve 255, the first sealing sleeve 255 is retracted into the fixed frame 241 to protect the first sealing sleeve 255, preventing the staff from causing wear to the first sealing sleeve 255 during daily cleaning and maintenance of the fermentation plate, which is beneficial to increasing the service life of the first sealing sleeve 255. In addition, each time the first sealing sleeve 255 is pushed out of the fixed frame 241, a brush is used to clean the materials above the first sealing sleeve 255 to prevent the materials from affecting the use of the first sealing sleeve 255, thereby enhancing the sealing performance between the cylinder cover 21 and the cylinder body 2.

One end of the second spring 265 is fixedly connected to the limit plate 264, and the other end is fixedly connected to the cylinder cover 21.

[0055] A first chute 212 is defined on the bottom surface of the cylinder cover 21. A guide rod 266 is fixedly mounted on the cylinder cover 21 and disposed within the first chute 212. A lifting block 267 is slidably mounted on the guide rod 266. A third spring 268 is sleeved on the guide rod 266. One end of the third spring 268 is fixedly connected to the lifting block 267, and the other end is fixedly connected to the cylinder cover 21. A push block 269 is fixedly mounted on the lifting block 267. The sidewall of the push block 269 adjacent to the third slide bar 261 is provided with an inclined surface, and the push block 269 abuts against the third slide bar 261 on the inclined surface. A top block 281 is fixedly mounted on the fixed frame 241 to push the lifting block 267. The top block 281 extends beyond the fixed frame 241.

[0056] When the cylinder cover 21 is closed on the cylinder body 2, the top block 281 will contact the lifting block 267 on the cylinder cover 21, and the top block 281 will push the lifting block 267 to slide on the guide rod 266 and compress the third spring 268. When the lifting block 267 rises, it will drive the push block 269 to move upward. Through the action of the inclined surface on the push block 269, the push block 269 presses against the third slide bar 261 and pushes the third slide bar 261 toward the center of the cylinder cover 21. When the third slide bar 261 moves closer to the center of the cylinder cover 21, it pushes the second sealing sleeve 263 out of the first receiving groove 211, and the second sealing sleeve 263 will contact with the first receiving groove 211. Figure 2 The discharge devices 4 at the position shown are offset from each other, thereby enhancing the sealing performance between the inner side of the semi-annular cylinder cover 21 and the discharge device 4, and preventing the gap between the semi-annular cylinder cover 21 and the discharge device 4 from causing air to enter the cylinder body 2 and affect the fermentation process of the material.

[0057] When the cylinder cover 21 leaves the cylinder body 2, the lifting block 267 loses the pressure of the top block 281. The third spring 268 pushes the lifting block 267 downward to slide back to its original position, and the second spring 265 pushes the third slide bar 261 to move outward from the cylinder cover 21. The third slide bar 261 drives the second sealing sleeve 263 to retract into the first receiving groove 211 to protect the second sealing sleeve 263 and reduce the exposure time of the second sealing sleeve 263. The brush cleans the material when the second sealing sleeve 263 is retracted and extended to prevent the material from affecting the use of the second sealing sleeve 263. This helps to enhance the performance of the second sealing sleeve 263 and the sealing performance of the cylinder cover 21 on the cylinder body 2.

[0058] Reference Figure 7 、 Figure 8 and Figure 9 The cylinder cover 21 is provided with a mounting groove 213 and a second receiving groove 214. The second receiving groove 214 is arranged on the vertical side walls of the two semi-annular cylinder covers 21 that are spliced ​​together. A fourth slide rod 291 is slidably installed on the cylinder cover 21. One end of the fourth slide rod 291 extends into the mounting groove 213 and the other end extends into the second receiving groove 214. A third mounting plate 292 is fixedly installed at one end of the fourth slide rod 291 extending into the second receiving groove 214. A third sealing sleeve 293 is fixedly installed on the third mounting plate 292. The third sealing sleeve 293 is a soft hollow rubber sleeve. A brush is also fixedly installed on the groove wall of the second receiving groove 214.

[0059] The fourth slide bar 291 extends into one end of the mounting groove 213 and is fixedly installed with a push plate 294, and a fixed plate 295 is fixedly connected to the push plate 294, and a second slide groove 2951 is provided on the fixed plate 295, and a movable rod 296 is fixedly connected to the third slide bar 261, and the end of the movable rod 296 away from the third slide bar 261 extends into the second slide groove 2951 on the fixed plate 295, and the end of the movable rod 296 away from the third slide bar 261 is fixedly installed with a third protruding rod 2961, and the movable rod 296 is slidably connected to the fixed plate 295 through the third protruding rod 2961.

[0060] When the third slide bar 261 moves toward the center of the cylinder cover 21, the third slide bar 261 drives the movable rod 296 to move. When the movable rod 296 moves toward the center, the movable rod 296 will slide in the fixed plate 295, and at the same time will resist the fixed plate 295 to push the fixed plate 295 to move toward the second receiving groove 214. The fixed plate 295 drives the push plate 294 to push the fourth slide bar 291 to move. The fourth slide bar 291 pushes the third mounting plate 292 to move and push the third sealing sleeve 293 out of the second receiving groove 214. After the third sealing sleeve 293 is pushed out of the second receiving groove 214, it will resist the side wall of the other semi-annular cylinder cover 21, which is beneficial to enhance the sealing performance of the joint position of the two semi-annular cylinder covers 21, and prevent the two semi-annular cylinder covers 21 from having gaps at the joint position when they are joined together, and air entering through the gaps affects the anaerobic fermentation process.

[0061] When the third slide bar 261 moves toward the outside of the cylinder cover 21, the third slide bar 261 drives the movable rod 296 to move, and the movable rod 296 pulls the fixed plate 295 back to its original position through the third protruding rod 2961. The fixed plate 295 drives the fourth slide bar 291 to move so that the third sealing sleeve 293 is retracted into the second receiving groove 214, reducing the time that the third sealing sleeve 293 is exposed to the outside of the cylinder cover 21 to protect the third sealing sleeve 293, which is beneficial to enhancing the service life of the third sealing sleeve 293. The third sealing sleeve 293 is cleaned by a brush when extending and retracting to prevent materials from sticking to the third sealing sleeve 293 and affecting the sealing effect.

[0066] Reference Figure 10 、 Figure 11 、 Figure 13 and Figure 14 A slewing support bearing 443 is fixedly installed on the lifting platform 44. The slewing support bearing 443 is an external gear slewing bearing. The inner and outer rings of the slewing support bearing 443 can rotate with each other. The lifting platform 44 is fixedly connected to the outer ring of the slewing support bearing 443. A turntable 45 is fixedly installed on the inner ring of the slewing support bearing 443. A slewing motor 451 is fixedly installed on the turntable 45. The output shaft of the slewing motor 451 is downwardly arranged. The output shaft of the slewing motor 451 is fixedly connected with a slewing gear 452. The slewing gear 452 is meshed with the external teeth of the slewing support bearing 443.

The second roller 454 extends into the third guide rail 455 and is slidably connected to the third guide rail 455. When the turntable 45 follows the lifting platform 44 to rise and fall, the second roller 454 moves up and down in the third guide rail 455. When the turntable 45 rotates, the second roller 454 drives the rotating drum 42 to rotate synchronously.

[0067] Two rotating rods 461 are rotatably mounted on the turntable 45. The two rotating rods 461 are symmetrically arranged. Blades 462 are spirally arranged on the rotating rods 461. A reduction motor 463 is fixedly mounted on the turntable 45 to control the rotation of the rotating rods 461. A vertically elongated discharge port 421 is formed on the rotating drum 42. The rotating rods 461 pass through the discharge port 421 on the rotating drum 42 and extend out of the rotating drum 42. The rotating drum 42 is provided with a blocking assembly 47 for controlling the flow of material at the discharge port 421. The blocking assembly 47 includes an electric push rod 471, which is hinged to the inner wall of the rotating drum 42. The output shaft of the electric push rod 471 is fixedly connected to a push piece 472. One end of the push piece 472 is hinged to the inner wall of the rotating drum 42. The hinge position between the electric push rod 471 and the push piece 472 is located in the center of the push piece 472. A baffle 473 is fixedly connected to the push piece 472. The width of the baffle 473 is the same as the width of the discharge port 421. The lower edge of the baffle 473 is the same height as the bottom end of the discharge port 421. The upper edge of the baffle 473 is higher than the height at which the material in the cylinder 2 can be stacked. There is a distance between the upper edge of the baffle 473 and the top of the discharge port 421.

[0068] When the fermentation tray is not in use, the baffle 473 is fitted on the rotating drum 42 to close the discharge port 421, the two cylinder covers 21 are assembled to close the cylinder body 2, and the rotating rod 461 stays above the cylinder cover 21 and the baffle 473. When feeding, the two semi-annular cylinder covers 21 are opened to the maximum and are higher than the rotating rod 461. The first motor 434 controls the screw rod 433 to rotate, and the lifting platform 44 slides downward on the support column 43. The lifting platform 44 drives the rotating rod 461 to descend to the position where the upper edge of the baffle 473 is at the maximum height of the material accumulation. After the fermented material enters the cylinder body 2, the material pile When the top of the accumulation reaches the height of the rotating rod 461, the reduction motor 463 controls the rotating rod 461 to rotate and push the material. At the same time, the rotary motor 451 on the turntable 45 controls the rotating gear 452 to rotate so that the turntable 45 rotates. When the turntable 45 rotates, it drives the rotating rod 461 to rotate in the cylinder 2. At the same time, the second roller 454 connected to the turntable 45 abuts against the third guide rail 455 to drive the rotating drum 42 to rotate. The rotating rod 461 rotates while rotating in the cylinder 2, and the material reaching the height of the rotating rod 461 is flattened in the cylinder 2, so that the material can be quickly and evenly filled in the cylinder 2.

[0069] After the feeding is completed, the rotating rod 461 rotates to the splicing position of the two semi-annular cylinder covers 21 and rises to the highest point of the discharge port 421. The semi-annular cylinder covers 21 are spliced ​​together to seal the cylinder body 2. At this time, the rotating rod 461 is located above the splicing line of the two semi-annular cylinder covers 21 and is parked.

[0070] After the fermentation is completed, the electric push rod 471 pulls the baffle 473 to open the discharge port 421, the reduction motor 463 controls the rotation of the rotating rod 461, the rotary motor 451 controls the rotation of the turntable 45 and the rotating rod 461, and the first motor 434 controls the rotating rod 461 to descend. The rotating rod 461 contacts the material and transports the material to the center through the discharge port 421 through the action of the spiral blade 462, and enters the rotating drum 42 for falling and discharge. The symmetrical arrangement of the double rotating rods 461 can double the loading and unloading efficiency. It only takes half a circle to complete the processing of a layer of material, and the material is peeled off layer by layer until all the material is emptied from the bottom of the fermentation tray. After the discharge is completed, the rotation stops, and the rotating rod 461 stops at the docking position of the semi-annular cylinder cover 21 again, waiting for the next fermentation cycle, so as to improve the convenience of the solid-state fermentation tray during use.

A wind temperature sensor is installed on the cylinder 2 near the air inlet pipe 53.

[0072] After fermentation is completed, the switch valve on the air outlet pipe 51 and the fan 52 are opened to extract the fermentation odor gas to prevent the fermentation odor from spreading in the working environment when the cylinder cover 21 is opened. When aerobic fermentation is carried out, the switch valves on the air outlet pipe 51 and the air inlet pipe 53 are opened at the same time, the fan 52 is used for air circulation, and the heat exchanger 54 adjusts and controls the air temperature, thereby providing a suitable fermentation environment for the material.

[0073] The implementation principle of the embodiment of the present application is: open the cylinder cover 21, and the feeding device 3 feeds the material into the cylinder 2. During feeding, the rotating rod 461 and the spiral blade 462 control the material to be flattened in the cylinder 2. After the material is filled in the cylinder 2, the cylinder cover 21 is closed, and the sealing system 24 is used to enhance the sealing between the cylinder cover 21 and the cylinder 2 to ensure that the anaerobic fermentation process of the material is completed in an oxygen-free environment. After the fermentation is completed, the fresh air system 5 is first used to extract the fermentation odor gas in the cylinder 2, and then the cylinder cover 21 is opened, and the material is controlled by the discharging device 4 to send the material out of the cylinder 2, so as to quickly complete a round of fermentation of the material, which is beneficial to improving the efficiency of the solid-state fermentation tray during use.
