Description
Technical Field
[0001] The invention relates to the technical field of bacterial strain cultivation, and in particular to a sludge fermentation compost bacterial strain cultivation device and a cultivation method. Background Art
[0002] Sludge composting fermentation bacteria are biological preparations developed by high-tech biotechnology. The Bacillus contained in the fermentation bacteria can produce a variety of digestive enzymes, with strong protease, amylase and lipase activities. It also has enzymes that degrade complex carbohydrates, such as pectinase, glucanase and cellulase, which have the function of destroying cell walls and decomposing colloids. Since the sludge micelles are negatively charged and the digestive enzymes are also negatively charged, the digestive enzymes and the sludge micelles form a counterattack, the sludge micelles are broken, the cell walls of the biological cells in the sludge are broken, and the cell water in the biological cells is released. The colloids in the sludge are decomposed by digestive enzymes, the interstitial water is released, and most of the "intra-membrane water" of the sludge is converted into surface water that is easy to remove. At the same time, the biological lysis effect is used to quickly destroy the cell structure of the living organism, so that the cell wall of the living organism is quickly broken and the "intra-membrane water" in the living organism is precipitated. After the sludge wall is broken, it changes from the original viscous elastic state to a fluidized state. At this point, the fermentation is completed. The efficient sludge fermentation bacteria have extremely strong aerobic fermentation and decomposition capabilities. Adding efficient sludge fermentation bacteria during the sludge composting fermentation process can increase the decomposition speed and efficiency. Inoculating bacterial agents during the sludge composting process will accelerate the composting maturity process.
[0003] At present, when cultivating sludge fermentation composting bacteria, the sludge raw materials are poured into the incubator, and an appropriate amount of culture water is poured into the incubator to dilute the sludge, and the operation is repeated many times, and the culture water is added again to simulate the microbial growth environment, and the cultivation operation is started. The overall operation is simple;
[0004] However, in the actual cultivation process, especially in the process of sludge dilution, there is no promoting component, and it only relies on natural dilution over time, which consumes a lot of time and reduces the overall work efficiency. In addition, there are a large number of large particles in the sludge, some of which are naturally accumulated by sludge, while some large particles are composed of other objects (such as metal). These substances have no beneficial effect on the cultivation process and will also affect the growth of microorganisms. Failure to deal with the large particles in time will seriously affect the subsequent cultivation operations. Therefore, a sludge fermentation composting strain cultivation equipment and a cultivation method are provided. Summary of the invention

[0014] A method for cultivating a sludge fermentation composting bacteria cultivation device comprises the following steps:
[0015] S1. First, collect the activated sludge from the municipal sewage treatment system, dehydrate the collected sludge with a dehydrator to make its moisture content 70%-80%, use the dehydrated sludge as the raw material for bacterial culture, pour the sludge raw material into the funnel, the sludge enters the incubator through the fixed cylinder, pour the culture water into the incubator, and add the bacterial suspension, prepare the bacterial suspension by constant temperature aerobic acclimation, activation and enrichment culture of municipal sludge, and centrifugal extraction of the suspension, start the motor, and the motor drives the fixed cylinder through the first gear and the second gear. The fixed drum rotates, the fixed drum drives the fixed ring to rotate, and the fixed drum drives the stirring rod to rotate, centrifuging the sludge so that the sludge and clean water are fully integrated to form mud, and then culture water is added in batches and aerated. In this process, when the sludge turns brown, water can be added, and the amount of water added gradually increases. At the same time, nutrients can be added during the water addition process to ensure the nutrient amount required for the normal growth of the sludge bacteria. The three processes of aeration, static sedimentation and water inlet are repeated until the bacteria concentration reaches the production requirement;
[0016] S2. During the process of pouring the sludge raw material into the incubator, under the action of the slide plate and the annular groove, when the slide plate is in the circular part, the rolling ring is on top and does not roll the sludge in the filter ring. When the slide plate moves to the raised part, it drives the rolling ring to move downward relative to the stirring rod. When the rolling ring and the bottom of the incubator are against each other, the slide plate will continue to drive the first right-angle rod and the control cylinder to move downward, compressing the third spring, so as to better complete the crushing operation of large particles in the filter ring.
[0017] S3, after the rolling ring and the bottom of the culture vessel are against each other, the large particles enter the rolling groove, and are crushed under the action of the rolling plate. At this time, the second spring is in a compressed state. During this process, if the large particles are crushed, the contact rod and the transmission ring are disconnected. If the large particles are not crushed, the contact rod and the transmission ring are against each other and drive the transmission ring to move upward, and the transmission ring drives the first switch rod to move upward. In the process of the right-angle rod and the control cylinder moving downward relative to the rolling ring, the two first switch rods finally against each other, and the hydraulic rod is started;
[0018] S4. When the hydraulic rod is activated, the hydraulic rod drives the moving plate to move to the right, and the moving plate drives the baffle to move to the right through the third right-angle rod, the discharge hole is opened, and the material on the lower side of the rolling ring enters the control cavity through the discharge hole, and then falls on the upper side of the filter screen, the liquid passes through the filter screen and is discharged from the drain pipe, and the large particles remain on the upper side of the filter screen, thereby completing the separation operation of the large particles in the sludge. At the same time, the hydraulic rod will also drive the auxiliary plate to move to the right through the second right-angle rod, and the auxiliary plate drives the second rack to move to the right, the second rack drives the first rack to move upward through the first gear, and the first rack drives the sealing ring to move upward through the connecting rod, and the outer wall of the sealing ring and the inner wall of the rolling ring are against each other, so that a closed space is formed between the sealing ring, the rolling ring, and the incubator (the lower side of the filter screen is fixedly connected to the incubator through the connecting ring, and the connecting ring is also a component of this closed space), so as to reduce the internal material of the rolling ring from entering the control cavity through the discharge hole, and other materials in the incubator move in the same way, thereby reducing unnecessary loss of materials;
[0019] S5. When the filter moves to the right, the angle between the rotating plate and the filter becomes smaller, and the large particles will stay between the rotating plate and the filter. When the filter returns to its original position, the angle between the rotating plate and the filter becomes smaller and becomes an acute angle. At this time, the large particles move along the rotating plate under the action of their own gravity and are finally discharged from the discharge pipe.
[0020] S6. After the material enters the control chamber through the discharge hole, large particles remain on the upper side of the filter, which will increase the weight of the filter, causing the filter to drive the positioning rod to move downward and compress the first spring. When the filter is too heavy, it means that there are many large particles, reminding the staff to take corresponding measures.
[0021] The beneficial effects of the present invention are:
[0022] 1. First, after placing the sludge in the incubator, the sludge is separated and stirred under the action of the processing components, so that the sludge and the culture water are quickly mixed together, thereby accelerating the cultivation rate. In the process, the sludge can be crushed to crush the large particles in the sludge, further accelerating the sludge mixing efficiency;
[0023] 2. In the process of sludge treatment, it can automatically select according to the treatment effect of large particles in the sludge. If the large particles are crushed, the device will operate normally. If the large particles are not crushed, the large particles will be discharged and filtered out. The staff will analyze the reasons for the existence of large particles in the subsequent cultivation process to reduce the generation of large particles and improve the cultivation effect.
[0024] 3. When separating and filtering large particles, if there are a lot of large particles, it means that there is an abnormality in the device as a whole, and the warning light will light up to remind the corresponding staff to carry out subsequent processing, thereby better ensuring the progress of the cultivation operation.

On the outside of the moving cylinder 3, the fixed cylinder 202 is located at the lower side of the fixed ring 201 and is rotatably connected to the fixed ring 201, the fixed ring 201 is fixedly connected to the incubator 1 through a plurality of inclined rods, the upper side of the filter ring 203 is fixedly connected to the fixed cylinder 202, the lower side of the filter ring 203 is fixedly connected to the incubator 1, the number of stirring rods 204 is multiple groups, the multiple groups of stirring rods 204 are circumferentially symmetrically arranged, the multiple groups of stirring rods 204 are located at the lower side of the fixed ring 201 and are fixedly connected to the fixed ring 201, the multiple groups of stirring rods 204 penetrate the rolling ring 205 and are slidably connected to the rolling ring 205, the outer side of the rolling ring 205 is fixedly sleeved with a cleaning ring 208, and the cleaning ring 208 and the filter ring 203 are against each other;
[0036] First, when it is necessary to cultivate the sludge fermentation composting bacteria, pour the sludge raw material into the funnel 4, the sludge enters the culture vessel 1 through the fixed cylinder 202, and the culture water is poured into the culture vessel 1, and the motor 5 is started. The motor 5 drives the fixed cylinder 202 to rotate through the first gear 6 and the second gear 7, and the fixed cylinder 202 drives the fixed ring 201 to rotate, and the fixed cylinder 202 drives the stirring rod 204 to rotate, centrifuge the sludge, so that the sludge and the clean water are fully integrated together, and at the same time, it also drives the rolling ring 205 to move up and down, and rolls the sludge inside the filter ring 203 to accelerate the fusion efficiency and crush the large particles in the sludge as much as possible. The rolling ring 205 that moves up and down drives the cleaning ring 208 to move up and down to clean the inner wall of the filter ring 203, thereby reducing the possibility that the sludge adheres to the filter ring 203 and affects the normal filtering effect of the filter ring 203;
[0037] like Figure 3 , Figure 4 , Figure 5 A sliding assembly for controlling the rolling ring 205 to move up and down is installed in the fixed cylinder 202, and the sliding assembly includes an annular groove 206 and a slide plate 211. An annular groove 206 is opened in the fixed cylinder 202, and the slide plate 211 is located in the annular groove 206 and is slidably connected to the annular groove 206. A first right-angle rod 210 is fixedly connected to the outer side of the slide plate 211, and a control cylinder 209 is fixedly connected to one end of the first right-angle rod 210 away from the slide plate 211, and a third spring 223 is fixedly connected between the control cylinder 209 and the rolling ring 205;
[0038] First, the cross section of the annular groove 206 is not a complete circle, and a part thereof bulges downward, so that when the stirring rod 204 drives the rolling ring 205 to rotate, under the action of the slide plate 211 and the annular groove 206, when the slide plate 211 is in the circular part, the rolling ring 205 is on top and does not crush the sludge in the filter ring 203. When the slide plate 211 moves to the bulged part, it drives the rolling ring 205 to move downward relative to the stirring rod 204. When the rolling ring 205 and the bottom of the incubator 1 are against each other, the slide plate 211 will continue to drive the first right-angle rod 210 and the control cylinder 209 to move downward, compressing the third spring 223, so as to better complete the crushing operation of large particles in the filter ring 203.

[0040] First, the two first switch rods 217 are similar to contact switches in real life. When the two first switch rods 217 are against each other, the corresponding power element will be started. Secondly, after the rolling ring 205 and the bottom of the culture vessel 1 are against each other, the large particles enter the rolling groove 212. Under the action of the rolling plate 213, the large particles are crushed. At this time, the second spring 218 is in a compressed state. During this process, if the large particles are crushed, the contact rod 219 and the transmission ring 221 are disconnected. If the large particles are not crushed, the contact rod 219 and the transmission ring 221 are against each other and drive the transmission ring 221 to move upward. The transmission ring 221 drives the first switch rod 217 to move upward.

The separation detection assembly includes a discharge hole 228, a hydraulic rod 230, a control chamber 232, and a filter screen 238. The culture vessel 1 is provided with a control chamber 232. A drainage pipe 231 is fixedly connected to the lower side of the control chamber 232. A discharge pipe 236 is also fixedly connected to the lower side of the control chamber 232. The hydraulic rod 230 is located in the control chamber 232 and is fixedly connected to the control chamber 232. The control chamber 232 is connected to the culture vessel 1 through the discharge hole 228. The interior of the container 1 is connected, the hydraulic rod 230 and the two second switch rods 224 are matched and arranged, the output end of the hydraulic rod 230 is fixedly connected to the moving plate 233, the filter screen 238 is located on the upper side of the moving plate 233 and is slidably connected to the moving plate 233 up and down, the output end of the hydraulic rod 230 is also fixedly connected to the third right-angle rod 243, and the end of the third right-angle rod 243 away from the hydraulic rod 230 is fixedly connected to the baffle 244, and the baffle 244 is located on the lower side of the discharge hole 228 and abuts against the discharge hole 228;
[0042] First, the two first switch rods 217 are connected to the hydraulic rod 230 through a wire. When the two first switch rods 217 are against each other, the hydraulic rod 230 is activated. Under normal circumstances, the baffle 244 is located at the lower side of the discharge hole 228, and the discharge hole 228 is in a closed state. When the hydraulic rod 230 is activated, the hydraulic rod 230 drives the movable plate 233 to move rightward, and the movable plate 233 drives the baffle 244 to move rightward through the third right-angle rod 243, and the discharge hole 228 is opened. The material on the lower side of the rolling ring 205 enters the control chamber 232 through the discharge hole 228, and then falls to the upper side of the filter screen 238. The liquid passes through the filter screen 238 and is discharged from the drain pipe 231, and the large particles remain on the upper side of the filter screen 238, thereby completing the separation operation of the large particles in the sludge.
[0043] Two second right-angle rods 242 are fixedly connected to the upper side of the moving plate 233, and the same auxiliary plate 241 is fixedly connected to the side of the two second right-angle rods 242 away from the moving plate 233. A sixth spring 229 is fixedly connected between the side of the auxiliary plate 241 away from the second right-angle rods 242 and the control chamber 232, and a second rack 247 is also fixedly connected to the side of the auxiliary plate 241 away from the second right-angle rods 242. A transmission rod 239 is rotatably connected in the control chamber 232, and two third gears are fixedly sleeved on the outer side of the transmission rod 239. 240, one of the third gears 240 is meshed with the second rack 247, a connecting rod 214 is slidably sleeved on the upper side of the control chamber 232, a first rack 215 is fixedly connected to the lower side of the connecting rod 214, another third gear 240 is meshed with the first rack 215, a sealing groove 227 is opened on the upper side of the culture vessel 1, a sealing ring 207 is slidably sleeved in the sealing groove 227, the sealing ring 207 is located on the inner side of the rolling ring 205 and abuts against the rolling ring 205, and the connecting rod 214 and the sealing ring 207 are fixedly connected;
[0044] When the hydraulic rod 230 drives the movable plate 233 to move to the right, the hydraulic rod 230 will also drive the auxiliary plate 241 to move to the right through the second right-angle rod 242, and the auxiliary plate 241 drives the second rack 247 to move to the right, and the second rack 247 drives the first rack 215 to move upward through the first gear 6, and the first rack 215 drives the sealing ring 207 to move upward through the connecting rod 214, and the outer wall of the sealing ring 207 and the inner wall of the rolling ring 205 are against each other, so that a closed space is formed between the sealing ring 207, the rolling ring 205, and the incubator 1 (the lower side of the filter screen 238 is fixedly connected to the incubator 1 through the connecting ring 237, and the connecting ring 237 is also a component of this closed space), so that when the material inside the rolling ring 205 enters the control chamber 232 through the discharge hole 228, other materials in the incubator 1 move in the same way, thereby reducing unnecessary loss of materials;
[0045] A rotating rod 235 is rotatably connected in the control chamber 232, a rotating plate 234 is fixedly sleeved on the outer side of the rotating rod 235, and two connecting rings 237 are fixedly connected to one side of the rotating plate 234 close to the filter screen 238, and the two connecting rings 237 are rotatably connected to the filter screen 238;
[0046] Since the rotating rod 235 is fixedly connected to the inner wall of the control chamber 232, when the filter screen 238 moves to the right, the angle between the rotating plate 234 and the filter screen 238 becomes smaller, and the large particles will stay between the rotating plate 234 and the filter screen 238. When the filter screen 238 returns to its original position, the angle between the rotating plate 234 and the filter screen 238 becomes smaller and becomes an acute angle. At this time, the large particles move along the rotating plate 234 under the action of their own gravity and are finally discharged from the discharge pipe 236.

[0048] First, the two second switch rods 224 are similar to contact switches in real life. When the two second switch rods 224 are against each other, the warning light 8 lights up to remind the corresponding staff. After the material enters the control chamber 232 through the discharge hole 228, large particles remain on the upper side of the filter screen 238, which will increase the weight of the filter screen 238, causing the filter screen 238 to drive the positioning rod 246 to move downward, compressing the first spring 216. When the filter screen 238 is too heavy, it means that there are a lot of large particles, reminding the staff to take corresponding measures.
[0049] A method for cultivating a sludge fermentation composting bacteria cultivation device comprises the following steps:
[0050] S1. First, collect the activated sludge from the municipal sewage treatment system, dehydrate the collected sludge with a dehydrator to make its moisture content 70%-80%, use the dehydrated sludge as the raw material for bacterial culture, pour the sludge raw material into the funnel 4, and the sludge enters the culture vessel 1 through the fixed cylinder 202, pour the culture water into the culture vessel 1, and add a certain concentration of bacterial suspension (constant temperature aerobic acclimation activation enrichment culture municipal sludge, centrifugal extraction suspension), start the motor 5, the motor 5 drives the fixed cylinder 202 to rotate through the first gear 6 and the second gear 7, and the fixed cylinder 202 The fixed ring 201 is driven to rotate, and the fixed cylinder 202 drives the stirring rod 204 to rotate, and the sludge is centrifuged to make the sludge and clean water fully blended together to form mud, and then the culture water is added in batches and aerated. In this process, when the sludge turns brown, water can be added, and the amount of water added gradually increases. At the same time, nutrients can be added during the water addition process to ensure the nutrient amount required for the normal growth of the sludge bacteria. The three processes of anaerobic aeration, static sedimentation and water inlet are repeated until the bacteria concentration reaches the production requirement. The above are all existing technologies and no unnecessary elaboration is made;
[0051] S2. During the process of pouring the sludge raw material into the incubator 1, under the action of the slide plate 211 and the annular groove 206, when the slide plate 211 is in the circular part, the rolling ring 205 is on top and does not roll the sludge in the filter ring 203. When the slide plate 211 moves to the raised part, it drives the rolling ring 205 to move downward relative to the stirring rod 204. When the rolling ring 205 and the bottom of the incubator 1 are against each other, the slide plate 211 will continue to drive the first right-angle rod 210 and the control cylinder 209 to move downward, compressing the third spring 223, so as to better complete the crushing operation of the large particles in the filter ring 203.
[0052] S3, after the rolling ring 205 and the bottom of the culture vessel 1 are against each other, the large particles enter the rolling groove 212, and are crushed under the action of the rolling plate 213. At this time, the second spring 218 is in a compressed state. During this process, if the large particles are crushed, the contact rod 219 and the transmission ring 221 are disconnected. If the large particles are not crushed, the contact rod 219 and the transmission ring 221 are against each other and drive the transmission ring 221 to move upward, and the transmission ring 221 drives the first switch rod 217 to move upward. In the process of the right-angle rod and the control cylinder 209 moving downward relative to the rolling ring 205, the two first switch rods 217 finally against each other, and the hydraulic rod 230 is started;
[0053] S4. When the hydraulic rod 230 is activated, the hydraulic rod 230 drives the movable plate 233 to move rightward, and the movable plate 233 drives the baffle plate 244 to move rightward through the third right-angle rod 243, and the discharge hole 228 is opened. The material on the lower side of the rolling ring 205 enters the control chamber 232 through the discharge hole 228, and then falls on the upper side of the filter screen 238. The liquid passes through the filter screen 238 and is discharged from the drain pipe 231. The large particles remain on the upper side of the filter screen 238, thereby completing the separation operation of the large particles in the sludge. At the same time, the hydraulic rod 230 also drives the auxiliary plate 241 to move rightward through the second right-angle rod 242, and the auxiliary plate 241 drives the second gear The rack 247 moves to the right, the second rack 247 drives the first rack 215 to move upward through the first gear 6, and the first rack 215 drives the sealing ring 207 to move upward through the connecting rod 214, and the outer wall of the sealing ring 207 and the inner wall of the rolling ring 205 are against each other, so that a closed space is formed between the sealing ring 207, the rolling ring 205, and the incubator 1. The lower side of the filter screen 238 is fixedly connected to the incubator 1 through the connecting ring 237, and the connecting ring 237 is also a component of this closed space, which reduces the internal material of the rolling ring 205 from entering the control chamber 232 through the discharge hole 228. When other materials in the incubator 1 move in the same way, it reduces unnecessary loss of materials;
[0054] S5. When the filter screen 238 moves to the right, the angle between the rotating plate 234 and the filter screen 238 becomes smaller, and the large particles will stay between the rotating plate 234 and the filter screen 238. When the filter screen 238 returns to its original position, the angle between the rotating plate 234 and the filter screen 238 becomes smaller and becomes an acute angle. At this time, the large particles move along the rotating plate 234 under the action of their own gravity and are finally discharged from the discharge pipe 236.
[0055] S6. After the material enters the control chamber 232 through the discharge hole 228, large particles remain on the upper side of the filter screen 238, which will increase the weight of the filter screen 238, causing the filter screen 238 to drive the positioning rod 246 to move downward, compressing the first spring 216. When the filter screen 238 is too heavy, it means that there are many large particles, reminding the staff to take corresponding measures.
[0056] In the present invention, first, the activated sludge of the urban sewage treatment system is collected, and the collected sludge is dehydrated by a dehydrator to make its water content 70%-80%, and the dehydrated sludge is used as a raw material for bacterial culture, and the sludge raw material is poured into the funnel 4, and the sludge enters the culture vessel 1 through the fixed cylinder 202, and the culture water is poured into the culture vessel 1, and a certain concentration of bacterial suspension is added (constant temperature aerobic acclimation activation enrichment culture of municipal sludge, centrifugal extraction of suspension), and the motor 5 is started. The motor 5 drives the fixed cylinder 202 to rotate through the first gear 6 and the second gear 7, and the fixed cylinder 202 drives the fixed ring 201 to rotate, and the fixed cylinder 202 drives the stirring rod 204 to rotate, and the sludge is centrifuged to make the sludge and clean water fully merge together to form a mud. slurry, and then add culture water in batches and aerate. During this process, when the sludge turns brown, water can be added, and the amount of water added gradually increases. At the same time, nutrients can be added during the water addition process to ensure the nutrient amount required for the normal growth of the sludge bacteria. The three processes of aeration, static sedimentation and water intake are repeated until the bacteria concentration reaches the production requirement. The above are all prior arts and no unnecessary details are given. In the process of pouring the sludge raw material into the culture vessel 1, under the action of the slide plate 211 and the annular groove 206, when the slide plate 211 is in the circular part, the rolling ring 205 is on it and will not roll the sludge in the filter ring 203. When the slide plate 211 moves to the convex part, it will drive the rolling ring 205 relative to the stirring rod 2 04 moves downward. When the rolling ring 205 and the bottom of the incubator 1 are in contact with each other, the slide plate 211 will continue to drive the first right-angle rod 210 and the control cylinder 209 to move downward, compressing the third spring 223, so as to better complete the crushing operation of the large particles in the filter ring 203. After the rolling ring 205 and the bottom of the incubator 1 are in contact with each other, the large particles enter the rolling groove 212. Under the action of the rolling plate 213, the large particles are crushed. At this time, the second spring 218 is in a compressed state. During this process, if the large particles are crushed, the contact rod 219 and the transmission ring 221 are disconnected. If the large particles are not crushed, the contact rod 219 and the transmission ring 221 are in contact with each other and drive the transmission ring 221 to move upward. The transmission ring 221 drives the first switch rod 217 to move upward. In the process of the right-angle rod and the control cylinder 209 moving downward relative to the rolling ring 205, the two first switch rods 217 finally collide with each other, and the hydraulic rod 230 is activated. When the hydraulic rod 230 is activated, the hydraulic rod 230 drives the moving plate 233 to move rightward, and the moving plate 233 drives the baffle plate 244 to move rightward through the third right-angle rod 243. The discharge hole 228 is opened, and the material on the lower side of the rolling ring 205 enters the control chamber 232 through the discharge hole 228, and then falls on the upper side of the filter screen 238. The liquid passes through the filter screen 238 and is discharged from the drain pipe 231, and the large particles remain on the upper side of the filter screen 238, thereby completing the separation operation of the large particles in the sludge. At the same time,The hydraulic rod 230 will also drive the auxiliary plate 241 to move rightward through the second right-angle rod 242, and the auxiliary plate 241 drives the second rack 247 to move rightward, and the second rack 247 drives the first rack 215 to move upward through the first gear 6, and the first rack 215 drives the sealing ring 207 to move upward through the connecting rod 214, and the outer wall of the sealing ring 207 and the inner wall of the rolling ring 205 are against each other, so that a closed space is formed between the sealing ring 207, the rolling ring 205, and the incubator 1 (the lower side of the filter screen 238 is fixedly connected to the incubator 1 through the connecting ring 237, and the connecting ring 237 is also a component of this closed space), so that when the material inside the rolling ring 205 enters the control chamber 232 through the discharge hole 228, other materials in the incubator 1 move in the same way, thereby reducing unnecessary loss of materials. When the filter 238 moves to the right, the angle between the rotating plate 234 and the filter 238 becomes smaller, and the large particles will stay between the rotating plate 234 and the filter 238. When the filter 238 returns to its original position, the angle between the rotating plate 234 and the filter 238 becomes smaller and becomes an acute angle. At this time, the large particles move along the rotating plate 234 under the action of their own gravity and are finally discharged from the discharge pipe 236. After the material enters the control chamber 232 through the discharge hole 228, the large particles remain on the upper side of the filter 238, which will increase the weight of the filter 238, so that the filter 238 drives the positioning rod 246 to move downward, compressing the first spring 216. When the filter 238 is too heavy, it means that there are many large particles, and the staff is reminded to take corresponding measures.
