Description

Technical Field

[0001] This invention belongs to the field of slurry impurity removal technology, and specifically relates to a slurry impurity removal device for environmentally friendly treatment of kitchen waste. Background Technology

[0002] Kitchen waste refers to the garbage and waste generated in daily life. When it is treated in an environmentally friendly way, the slurry and other materials are separated.

[0003] A search revealed that in the prior art, Chinese Patent Publication No. CN115921490B, published on March 12, 2024, discloses a hydraulic impurity removal and pulping device and a kitchen waste treatment system and method. The device includes a silo body and a silo cover sealing the silo body opening. The silo cover has a feed inlet and a water inlet.

Each set of recycling plates has several sets of air pumps evenly spaced on its top, and the output end of each set of air pumps is connected to the input end of one set of filling bag structures.

[0016] The beneficial effects of this invention are: 1. During the rolling grinding process, the initially separated slurry enters the collection pipe through the drain hole, driving the crushing blades on the transmission column to crush the impurities, forming a paste. After crushing, the fourth electric push rod is activated to lower the bonding ring. As the bonding ring descends, it scrapes off the remaining impurities on the inner wall of the impurity removal pipe and scrapes off the slurry impurities on the crushing blades through the bonding groove. The sealing of the bonding ring and the impurity removal pipe squeezes the paste impurities, separating them into slurry. The slurry enters the gauze pad through the drain hole for further separation. The weight of the accumulated slurry drives the compression spring to compress to a specified degree, which in turn drives the sliding block to press the pressure sensor. The pressure sensor reading is used to monitor the accumulated slurry level, improving the slurry equalization treatment effect and the slurry impurity removal effect.

[0017] 2. The outer walls of several sets of impurity removal tubes are engaged in the drain hole. The second electric push rod is activated to lower the disc body, causing several sets of grinding rings to slide in the auxiliary tank. Then, the second motor is activated to rotate the grinding rings. When the slurry flows into the collection tube, it first undergoes preliminary filtration through an activated carbon filter screen, and then begins to accumulate in the collection tube. As the weight of the accumulation increases, the collection tube slides on the outer wall of the impurity removal tube. While sliding, the sliding block slides in the sliding cavity to compress the spring. Subsequently, the grinding rings can be reversed to prevent impurities from entering the impurity removal tube again. This improves the pressure monitoring of the liquid level and the quantitative collection effect of the slurry.

[0018] 3. During the grinding process, when the grinding ring is squeezed against hard impurities, the noise is transmitted to the noise sensor. The noise sensor is used to locate the hard impurities. Then, one set of vacuum suction cups is positioned directly above the hard impurities. The fifth electric push rod is then activated to push the vacuum cylinder down, causing the vacuum suction cups to adhere to the surface of the hard impurities. At this time, the rotary jet valve is activated to blow off the impurities and slurry on the surface of the hard impurities. Then, the vacuum pump is activated to evacuate the air from the vacuum cylinder. The negative pressure vacuum cylinder, in conjunction with the vacuum suction cups, adsorbs the hard impurities, improving both the noise monitoring effect and the efficiency of hard impurity removal.

[0019] 4. Once the adsorbed hard impurities reach a specified quantity, the seventh electric push rod is activated, causing the mounting rod to slide upwards within the cavity to the designated position. Subsequently, the eighth electric push rod is activated, moving several sets of recovery plates closer to the grinding ring, positioning several sets of recovery tanks directly below several sets of vacuum suction cups. The angle is then finely adjusted by the fourth motor, after which the hard impurities are released from the vacuum suction cups and fall into the recovery tanks. The air pump is then activated to fill the filling bag structure, causing the filling bag structure to expand and encapsulate and limit the hard impurities, preventing them from falling off due to subsequent shaking. This improves the stability of the encapsulation of irregular impurities and enhances the recovery and processing efficiency of hard impurities.

[0025] This invention provides a slurry removal device for environmentally friendly treatment of kitchen waste. It includes a sealing assembly 1, exemplarily, such as... Figure 1 and Figure 2 As shown, a grinding component 2 is connected to the sealing component 1, a liquid extraction component 3 is installed on the inner wall of the sealing component 1, and a recovery component 4 is installed on the liquid extraction component 3.

[0026] For example, such as Figure 3As shown, the sealing assembly 1 includes a sealing box 101. A slot is provided on the top of the sealing box 101. A first electric push rod 102 is installed in the slot. A first motor 103 is installed on the output end of the first electric push rod 102.

A second motor 106 is installed on the output end of the second electric push rod 105.

[0027] For example, such as Figure 4 , Figure 5 and Figure 6 As shown, the grinding assembly 2 includes a disc body 201. The top of the disc body 201 is drivenly connected to the output end of a second motor 106. Several sets of grinding rings 202 are evenly spaced on the bottom of the disc body 201. An auxiliary inclined block 203 is connected between each pair of adjacent grinding rings 202. Several placement cavities 204 are arranged in a ring array on the bottom of each set of grinding rings 202. A set of fixed discs 205 is installed in each set of placement cavities 204. A set of third electric push rods 206 is installed on the bottom of each set of fixed discs 205. A set of third motors 207 is installed on the output end of each set of third electric push rods 206. A set of transmission columns 208 is drivenly connected to the output end of each set of third motors 207. Several sets of crushing blades 209 are arranged in a ring array on the outer wall of each set of transmission columns 208. Several sets of crushing blades 209 are arranged in a ring array on the bottom of each set of fixed discs 205. A set of fourth electric push rods 210 is installed. Each set of fourth electric push rods 210 has a set of fitting rings 211 installed on its output end. The inner wall of each set of fitting rings 211 is slidably connected to the outer wall of the transmission column 208. The outer wall of each set of fitting rings 211 is slidably connected to the placement cavity 204. Each set of fitting rings 211 has several sets of fitting grooves 212 arranged in a ring array. Each set of fitting grooves 212 is slidably connected to the outer wall of one set of crushing blades 209.

Each set of vacuum cylinders 214 has a set of rotary jet valves 217 sleeved on its outer wall.

[0028] During the grinding process, when the grinding ring is squeezed against hard impurities, the noise is transmitted to the noise sensor. The noise sensor is used to locate the hard impurities. Then, one set of vacuum suction cups 215 is positioned directly above the hard impurities. The fifth electric push rod 213 is then activated to push the vacuum cylinder 214 down, causing the vacuum suction cups 215 to adhere to the surface of the hard impurities. At this time, the rotary jet valve 217 is activated to blow off the impurities and slurry on the surface of the hard impurities. Then, the vacuum pump 216 is activated to evacuate the air from the vacuum cylinder 214. The negative pressure vacuum cylinder 214, in conjunction with the vacuum suction cups 215, adsorbs the hard impurities, improving both the noise monitoring effect and the efficiency of hard impurity removal.

[0029] For example, such as Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, the extraction assembly 3 includes an auxiliary disc 301. The outer wall of the auxiliary disc 301 is mounted on the inner wall of the sealed box 101. Several sets of auxiliary grooves 302 are evenly spaced on the top of the auxiliary disc 301. Each set of grinding rings 202 is slidably connected to the inner wall of the auxiliary groove 302. Several sets of noise sensors are arranged in a circular array on the bottom of the auxiliary disc 301. Several sets of drainage holes 303 are arranged in a circular array on each set of auxiliary grooves 302. The center of the top of the auxiliary disc 301 is... A cavity 304 is provided on the top. A sixth electric push rod 305 is installed on the bottom edge of the auxiliary disc 301. A connecting plate 306 is installed on the output end of the sixth electric push rod 305. The outer wall of the connecting plate 306 is slidably connected to the inner wall of the sealed box 101. Several sets of mounting brackets 307 are arranged in a circular array on the top of the connecting plate 306. Each set of mounting brackets 307 is equipped with a set of impurity removal pipes 308. The outer wall of each set of impurity removal pipes 308 is slidably connected to the inner wall of the drain hole 303. The outer walls of the fitting rings 211 are slidably connected to the inner walls of the impurity removal tubes 308. Two sets of sliding cavities 309 are symmetrically formed on the outer walls of each set of impurity removal tubes 308. Two sets of compression springs 310 are symmetrically installed at one end on the bottom inner wall of each set of sliding cavities 309. A sliding block 311 connects the other ends of the two sets of compression springs 310. Each set of sliding blocks 311 is slidably connected to the inner wall of the sliding cavity 309. A pressure sensor 312 is installed on the bottom inner wall of each set of sliding cavities 309. Each set of impurity removal tubes 308 has several sets of leakage holes arranged in a ring array at the bottom. Each set of impurity removal tubes 308 has a set of gauze pads 313 sleeved on the bottom. Each set of impurity removal tubes 308 has a set of liquid collection tubes 314 movably sleeved on the outer wall. Each set of liquid collection tubes 314 has two sets of transmission frames 315 symmetrically installed on the top. One end of each set of transmission frames 315 is installed on the outer wall of one set of sliding blocks 311. Each set of liquid collection tubes 314 has an activated carbon filter screen 316 installed on the inner wall.

[0030] The first electric push rod 102 is activated, causing the cover plate 104 to rise and disengage from the sealed box 101. Then, the first motor 103 is activated, causing the cover plate 104 to rotate. After rotation, the pre-treated kitchen waste is poured into several auxiliary troughs 302. During this process, the sixth electric push rod 305 is activated, causing the connecting plate 306 to rise. Once the connecting plate 306 reaches the designated position, it causes the outer walls of several sets of waste removal pipes 308 to engage with the drain holes 303. The second electric push rod 105 is activated, causing the disc body 201 to descend, allowing several sets of grinding rings 202 to slide within the auxiliary troughs 302. Then, the second motor 106 is activated. The grinding rings 202 rotate and grind the material. During the initial rolling grinding process, the slurry and impurities are squeezed and separated. Then, equal amounts of slurry and impurities fall into the impurity removal pipe 308 in batches. Several sets of auxiliary inclined blocks 203 can push the impurities falling onto the auxiliary disc 301 into the auxiliary tank 302. The initially separated slurry enters the collection pipe 314 through the drain hole. After the grinding and conveying to the specified quantity, several sets of fixed discs 205 are positioned directly above the impurity removal pipe. Then, the third electric push rod 206 is activated to drive the transmission column 208 into the impurity removal pipe. Then, the fourth electric push rod 210 is activated to push the outer wall of the fitting ring 211 to slide and connect to the impurity removal pipe. On the inner wall of the impurity removal tube 308, the third motor 207 is activated to drive the crushing blades on the transmission column 208 to rotate rapidly, crushing the impurities into a paste. After crushing, the fourth electric push rod 210 is activated to drive the bonding ring 211 to descend. As the bonding ring 211 descends, it scrapes off the remaining impurities on the inner wall of the impurity removal tube 308 and scrapes off the slurry on the crushing blades 209 through the bonding groove 212. The sealing of the bonding ring 211 and the impurity removal tube 308 is used to squeeze the paste impurities. The paste impurities are separated into slurry through the squeeze. The slurry enters the gauze pad layer 313 through the leakage hole, and then undergoes further separation through the gauze pad layer 313. When the slurry flows into the collection pipe 314, it first undergoes preliminary filtration through the activated carbon filter screen 316, and then begins to accumulate in the collection pipe 314. As the weight of the accumulation increases, the collection pipe 314 slides on the outer wall of the impurity removal pipe 308. Simultaneously, the sliding block 311 slides in the sliding cavity 309, compressing the compression spring 310. When the compression spring 310 is compressed to a specified degree, it will cause the sliding block 311 to compress the pressure sensor 312. The value of the accumulated liquid is monitored by the value of the pressure sensor 312. Subsequently, the impurities can be prevented from entering the impurity removal pipe by reversing the grinding ring 202, which improves the pressure monitoring of the liquid level and the quantitative collection effect of the slurry.

[0031] For example, such as Figure 12As shown, the recycling assembly 4 includes a recycling box 401. The top of the recycling box 401 is mounted on the bottom of the auxiliary disc 301. A seventh electric push rod 402 is mounted on the inner wall of the bottom of the recycling box 401. A fourth motor 403 is mounted on the output end of the seventh electric push rod 402. A mounting rod 404 is drivenly connected to the output end of the fourth motor 403. The outer wall of the mounting rod 404 is slidably connected to the cavity 304. The outer wall of the mounting rod 404 has a ring-shaped array of... Several sets of eighth electric push rods 405 are provided. Each set of eighth electric push rods 405 has a set of recycling plates 406 installed on its output end. Each set of recycling plates 406 has several sets of recycling slots 407 evenly spaced on its top. Each set of recycling slots 407 has a set of filling bag structures 408 installed on its inner wall. Each set of recycling plates 406 has several sets of air pumps 409 evenly spaced on its top. The output end of each set of air pumps 409 is connected to the input end of one set of filling bag structures 408.

[0032] Once the adsorbed hard impurities reach a specified quantity, the seventh electric push rod 402 is activated, causing the mounting rod 404 to slide upwards within the cavity 304 to a specified position. Subsequently, the eighth electric push rod 405 is activated, causing several sets of recovery plates 406 to move towards the grinding ring 202, positioning several sets of recovery tanks 407 directly below several sets of vacuum suction cups 215. The angle is then finely adjusted by the fourth motor 403, after which the hard impurities are released from the vacuum suction cups 215 and fall into the recovery tanks 407. Then, the air pump 409 is activated to fill the filling bag structure 408, causing the filling bag structure 408 to expand and wrap and limit the hard impurities, preventing them from falling off due to subsequent shaking. This improves the stability of the irregular impurity wrapping effect and enhances the recovery and processing effect of hard impurities.

[0033] During the rolling grinding process, the initially separated slurry enters the collection pipe 314 through the drain hole, driving the crushing blades on the transmission column 208 to crush the impurities, making them into a paste. After crushing, the fourth electric push rod 210 is activated to drive the bonding ring 211 to descend. As the bonding ring 211 descends, it scrapes off the impurities remaining on the inner wall of the impurity removal pipe 308 and scrapes off the impurities on the crushing blades 209 through the bonding groove 212. The sealing state of the bonding ring 211 and the impurity removal pipe 308 is used to squeeze the paste impurities. The paste impurities are separated by squeezing and the slurry enters the gauze pad 313 through the drain hole, where it is further separated. The weight of the accumulated slurry drives the compression spring 310 to compress to a specified degree, which in turn drives the sliding block 311 to squeeze the pressure sensor 312. The value of the pressure sensor 312 is used to monitor the value of the accumulated slurry, which improves the effect of equal volume treatment of slurry and the effect of slurry impurity removal.

[0034] The outer walls of several sets of impurity removal pipes 308 are engaged in the drain hole 303. The second electric push rod 105 is activated to drive the disc body 201 to descend, so that several sets of grinding rings 202 are slidably connected in the auxiliary tank 302. Then, the second motor 106 is activated to drive the several sets of grinding rings 202 to rotate and grind. When the slurry flows into the collection pipe 314, it first passes through the activated carbon filter screen 316 for preliminary filtration, and then begins to accumulate in the collection pipe 314. With the weight of the accumulation, the collection pipe 314 slides on the outer wall of the impurity removal pipe 308. At the same time, the sliding block 311 slides in the sliding cavity 309 to squeeze and compress the spring 310. Subsequently, the grinding rings 202 can be reversed to avoid impurities from entering the impurity removal pipe. This improves the pressure monitoring of the liquid level and the quantitative collection effect of the slurry.

[0035] During the grinding process, when the grinding ring is squeezed against hard impurities, the noise is transmitted to the noise sensor. The noise sensor is used to locate the hard impurities. Then, one set of vacuum suction cups 215 is positioned directly above the hard impurities. The fifth electric push rod 213 is then activated to push the vacuum cylinder 214 down, causing the vacuum suction cups 215 to adhere to the surface of the hard impurities. At this time, the rotary jet valve 217 is activated to blow off the impurities and slurry on the surface of the hard impurities. Then, the vacuum pump 216 is activated to evacuate the air from the vacuum cylinder 214. The negative pressure vacuum cylinder 214, in conjunction with the vacuum suction cups 215, adsorbs the hard impurities, improving both the noise monitoring effect and the efficiency of hard impurity removal.

[0036] Once the adsorbed hard impurities reach a specified quantity, the seventh electric push rod 402 is activated, causing the mounting rod 404 to slide upwards within the cavity 304 to a specified position. Subsequently, the eighth electric push rod 405 is activated, causing several sets of recovery plates 406 to move towards the grinding ring 202, positioning several sets of recovery tanks 407 directly below several sets of vacuum suction cups 215. The angle is then finely adjusted by the fourth motor 403, after which the hard impurities are released from the vacuum suction cups 215 and fall into the recovery tanks 407. Then, the air pump 409 is activated to fill the filling bag structure 408, causing the filling bag structure 408 to expand and wrap and limit the hard impurities, preventing them from falling off due to subsequent shaking. This improves the stability of the irregular impurity wrapping effect and enhances the recovery and processing effect of hard impurities.
