Abstract

This invention relates to the field of kitchen waste pretreatment, and particularly to a kitchen waste pretreatment device for a residential waste transfer station. It includes a pusher box, one end of which is equipped with a recycling auxiliary component, and the other end is connected to a biological deodorization box. In this invention, the rise in water level within the treatment chamber causes floating debris to rise. At this time, the output end of the condenser structure on the sliding tube and the input end of the cold air pipe are at the same height, causing grease and floating debris to rise to the water surface. The condenser structure is activated, and cold air is introduced into the treatment chamber through the cold air pipe. The cold air naturally descends, causing grease to begin to accumulate and condense. Then, a fourth electric pusher is activated to push the oil-absorbing pad to adsorb the condensed grease and debris. Subsequently, during drainage, residual grease is adsorbed through a quartz sand filter layer. The buoyancy enhances the adsorption effect of grease and floating debris, thereby improving the pretreatment effect of kitchen waste.

Description

Technical Field

[0001] This invention belongs to the field of kitchen waste pretreatment technology, and specifically relates to a kitchen waste pretreatment device for a residential waste transfer station. Background Technology

[0002] Currently, the method for handling sorted waste is to first store it at the waste sorting station until a certain amount is reached, and then transport it to different waste treatment plants for separate processing. Before this, kitchen waste needs to undergo pre-processing and sorting.

[0003] A search revealed that Chinese Patent Publication No. CN117259381B, published on September 20, 2024, discloses a pre-treatment dehydration device for kitchen waste. The device includes a squeezing bag and two rotating supports. The squeezing bag has several filter holes and can be filled with kitchen waste. Both ends of the squeezing bag are connected to the two rotating supports, which can rotate the ends of the squeezing bag. The rotation modes include centrifugal rotation, squeezing rotation, and cyclic squeezing. In centrifugal rotation, the two rotating supports rotate the ends of the squeezing bag in the same direction; in squeezing rotation, the two rotating supports rotate the ends of the squeezing bag in opposite directions. This embodiment uses two rotating supports to apply rotational kinetic energy to the squeezing bag, enabling squeezing dehydration, centrifugal dehydration, and combined squeezing and centrifugal dehydration of kitchen waste. This relatively simple structure achieves good dehydration results for kitchen waste.

[0004] However, the device still has the following drawbacks: the pulverized kitchen waste contains ferromagnetic metal impurities, plastic particles, and grease. If these are not sorted during the dehydration process, subsequent recycling will be limited, thus reducing the pre-treatment effect of kitchen waste. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a pre-treatment device for kitchen waste at a residential waste transfer station. It includes a push box, with a recycling auxiliary component installed at one end and a biological deodorization box connected to the other end. A mechanical gripping component is installed on one side wall of the push box, and a pre-treatment component is connected to the top of the recycling auxiliary component. A shredding box structure is installed on the top of the pre-treatment component.

[0006] The pretreatment component includes several sets of sliding tubes. Each set of sliding tubes has two sets of openings symmetrically formed on its outer wall. Each set of openings contains a condenser structure that supplies cold air to the treatment chamber through a cold air pipe. Each set of sliding tubes has a set of connecting pipes fitted onto its outer wall. Each set of connecting pipes contains a treatment chamber where rising water levels cause floating impurities to rise. Each set of connecting pipes has two sets of cold air pipes symmetrically connected to its inner wall. Each set of connecting pipes has a quartz sand filter layer installed on its bottom inner wall to absorb residual grease.

[0007] Furthermore, the recycling auxiliary component includes a transfer box, one end of which is connected to a push box. An input cavity is provided on the top of the transfer box. A first electric push rod is installed on the inner wall of the transfer box. A push plate is installed on the output end of the first electric push rod.

[0008] Furthermore, a top plate is installed on the top of one side wall of the push plate, and the top of the top plate is slidably connected to the top inner wall of the transfer box. A recycling bin is installed on one side wall of the top plate, and the top of the recycling bin is slidably connected to the top inner wall of the transfer box. A filter screen is installed on the inner wall of the recycling bin.

[0009] Furthermore, the pretreatment assembly also includes a pretreatment box, which is connected to the top of the transfer box. An inclined plate is installed on the inner wall of the pretreatment box, and a second electric push rod is installed on the bottom of the inclined plate. A sliding frame is installed on the output end of the second electric push rod, and the outer wall of the sliding frame is slidably connected to the inner wall of the pretreatment box.

[0010] Furthermore, two sets of placement cavities are symmetrically opened on the inner wall of the sliding frame. Each set of placement cavities is equipped with a set of first motors. A set of pressure plates is driven and connected to the output end of each set of first motors. The outer wall of each set of pressure plates is slidably connected to the inner wall of the sliding frame. Several sets of pressure sensors are equally spaced and clamped to one side wall of each set of pressure plates. Two sets of vacuum tubes are symmetrically installed on the bottom of each set of pressure plates. A set of third electric push rods is installed on the top inner wall of each set of vacuum tubes. A set of second motors is installed on the output end of each set of third electric push rods. Each set of sliding tubes is driven and connected to the output end of one of the sets of second motors.

[0011] Furthermore, each set of sliding tubes has two sets of sliding cavities symmetrically opened on its outer wall, and two sets of first compression springs are symmetrically installed on the inner wall of each set of sliding cavities. A limit block is connected between the other ends of the two sets of first compression springs, and each set of limit blocks is slidably connected in the sliding cavity. One end of a set of second compression springs is installed on the bottom of each set of sliding tubes, and a limit ring is installed on the other end of each set of second compression springs.

[0012] Furthermore, two sets of magnetic blocks are symmetrically installed on the outer wall of each set of sleeves, an electric ball valve is installed at the bottom of each set of sleeves, several sets of water injection pipes are connected at equal intervals on the outer wall of each set of sleeves, a set of insulating gauze is installed at one end of each set of water injection pipes, and each set of insulating gauze is installed on the outer wall of the sleeve.

[0013] Furthermore, two sets of fourth electric push rods are symmetrically installed on the top inner wall of each set of sleeves, and an oil-absorbing pad is connected between the output ends of the two sets of fourth electric push rods. The outer wall of the oil-absorbing pad is slidably connected to the processing chamber, and two sets of sliding push rods are slidably connected to the outer wall of each set of sleeves.

[0014] Furthermore, the mechanical gripping assembly includes a first electric slide, one end of which is mounted on a side wall of a push box. A transmission plate is driven to the output end of the first electric slide, and a layered box is mounted on the other end of the first electric slide. A robotic arm structure is mounted on the top edge of the transmission plate, and a support frame is mounted on the top of the transmission plate.

A third motor is mounted on the output end of the fifth electric push rod, and a disc body is driven to the output end of the third motor. A fixed plate is mounted on the bottom of the disc body.

[0015] Furthermore, a metal detector is installed on the bottom of the fixed plate, and several sets of sixth electric push rods are distributed in a ring array on the outer wall of the fixed plate. Each set of sixth electric push rods has a set of mounting blocks installed on its output end, and each set of mounting blocks has a set of vibration motors installed on its bottom. Each set of vibration motors has a set of stirring probes connected to its output end.

[0016] The beneficial effects of this invention are: 1. The rise in water level in the treatment chamber will cause floating debris to rise to the surface. At this time, the output end of the condenser structure on the sliding tube and the input end of the cold air pipe are at the same height. Grease and floating debris begin to rise to the water surface. The condenser structure is activated to input cold air into the treatment chamber through the cold air pipe. The cold air naturally descends, causing the grease to begin to accumulate and condense. Then, the fourth electric push rod is activated to push the oil-absorbing pad to adsorb the condensed grease and debris. Subsequently, during the drainage process, the residual grease is adsorbed through the quartz sand filter layer. The buoyancy improves the adsorption effect of grease and floating debris, while also improving the pretreatment effect of kitchen waste.

[0017] 2. Start the first motor to drive the pressure plate to rotate, so that one end of the two sets of pressure plates abuts against the inner wall of the sliding frame, and several sets of pressure sensors on the other end squeeze each other to ensure the sealing between the two sets of pressure plates, which is more conducive to the subsequent compression work. First, start the third electric push rod in the vacuum tube to push several sets of magnetic blocks into the kitchen waste. Then start the second motor to drive the sleeve pipe to rotate. While the sleeve pipe is rotating, it drives several sets of magnetic blocks to stir at a uniform speed in the kitchen waste, adsorbing the ferromagnetic metal impurities in the kitchen waste. The third electric push rod drives several sets of magnetic blocks to move up and down to ensure the adsorption range, which improves the adsorption effect of ferromagnetic metal impurities in the kitchen waste and improves the stirring effect of the kitchen waste.

[0018] 3. When processing kitchen waste, the first electric push rod is activated to move the push plate towards the end closer to the recycling bin. At this time, the kitchen waste falls onto the bottom inner wall of the transfer box. Then, the first electric push rod is activated again to push the push plate and move the kitchen waste into the push box. At this time, the recycling bin is located directly below several sets of connecting pipes. The electric ball valve is opened to allow water filtered through quartz sand to flow into the recycling bin. At this time, the magnetic block is deactivated, allowing the adsorbed ferromagnetic metal impurities to fall naturally into the filter screen on the inner wall of the recycling bin for recycling. During the subsequent operation of the recycling bin, its top is slidably connected to the top inner wall of the transfer box, improving the sealing effect of impurity recycling in the recycling bin.

[0019] 4. Push the kitchen waste onto the push box, activate the second electric slide to move the disc body directly above the kitchen waste, activate the fifth electric push rod to insert several sets of stirring probes into the kitchen waste, then activate the third motor to rotate the disc body, simultaneously stirring and flattening the kitchen waste with the stirring probes, and activate the vibration motor to vibrate the stirring probes. During this process, activate the sixth electric push rod to adjust and stir the stirring probes, and use a metal detector to detect residual ferromagnetic metal impurities. Then, activate the first electric slide to drive the robotic arm structure to separately grab the ferromagnetic metal impurities and plastic particles, placing them into the layered box. Finally, push the kitchen waste into the biological deodorization box, which improves both the stirring and crushing effect and the particle picking effect.

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] This invention provides a pre-treatment device for kitchen waste at a residential waste transfer station. It includes a pusher box 1, exemplarily, such as... Figure 1 As shown, a recycling auxiliary component 2 is installed on one end of the push box 1, a biological deodorization box 5 is connected to the other end of the push box 1, a mechanical gripping component 6 is installed on one side wall of the push box 1, a pre-treatment component 3 is connected to the top of the recycling auxiliary component 2, and a crushing box structure 4 is installed on the top of the pre-treatment component 3.

[0026] For example, such as Figure 2As shown, the recycling auxiliary component 2 includes a transfer box 201, one end of which is connected to the push box 1. An input cavity 202 is provided on the top of the transfer box 201. A first electric push rod 203 is installed on the inner wall of the transfer box 201. A push plate 204 is installed on the output end of the first electric push rod 203. The outer wall of the push plate 204 is slidably connected to the inner wall of the transfer box 201. A top plate 205 is installed on the top of one side wall of the push plate 204. The top of the top plate 205 is slidably connected to the top inner wall of the transfer box 201. A recycling box 206 is installed on one side wall of the top plate 205. The top of the recycling box 206 is slidably connected to the top inner wall of the transfer box 201. A filter screen is installed on the inner wall of the recycling box 206. Two sets of support columns 207 are symmetrically installed on the bottom of the transfer box 201.

[0027] When the kitchen waste is processed, the first electric push rod 203 is activated, which moves the push plate 204 towards the end near the recycling bin 206. At this time, the kitchen waste falls onto the bottom inner wall of the transfer box 201. Then, the first electric push rod 203 is activated again to push the push plate 204 and move the kitchen waste into the push box 1. At this time, the recycling bin 206 is located directly below several sets of connecting pipes 317. The electric ball valve 319 is opened, allowing water filtered through quartz sand to flow into the recycling bin 206. At this time, the magnetic block 318 is deactivated, allowing the adsorbed ferromagnetic metal impurities to fall naturally into the filter screen on the inner wall of the recycling bin 206 for recycling. During the subsequent operation of the recycling bin, its top is slidably connected to the top inner wall of the transfer box 201, which improves the sealing effect of impurity recycling in the recycling bin.

[0028] For example, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the pretreatment component 3 includes a pretreatment box 301, which is connected to the top of the transfer box 201. An inclined plate 302 is installed on the inner wall of the pretreatment box 301, and a second electric push rod 303 is installed on the bottom of the inclined plate 302. A sliding frame 304 is installed on the output end of the second electric push rod 303. The outer wall of the sliding frame 304 is slidably connected to the inner wall of the pretreatment box 301. Two sets of placement cavities are symmetrically opened on the inner wall of the sliding frame 304. Each set of placement cavities is equipped with a first motor 305. A set of pressure plates 306 is drivenly connected to the output end of each set of first motors 305. The outer wall of each set of pressure plates 306 is slidably connected to the inner wall of the sliding frame 304. On the wall, several sets of pressure sensors 307 are equally spaced and clipped onto one side wall of each set of pressure plates 306. Two sets of vacuum tubes 308 are symmetrically installed on the bottom of each set of pressure plates 306. A set of third electric push rods 309 is installed on the inner top wall of each set of vacuum tubes 308. A set of second motors 310 is installed on the output end of each set of third electric push rods 309. A set of sliding tubes 311 is drivenly connected to the output end of each set of second motors 310. Two sets of openings are symmetrically opened on the outer wall of each set of sliding tubes 311. A set of condenser structures 312 is installed in each set of openings. Two sets of sliding cavities are symmetrically opened on the outer wall of each set of sliding tubes 311. A set of sliding cavities is symmetrically installed on the inner wall of each set of sliding cavities. The system is equipped with two sets of first compression springs 313, with a limit block 314 connecting the other ends of the two sets of first compression springs 313. Each set of limit blocks 314 is slidably connected within a sliding cavity. One end of a set of second compression springs 315 is installed on the bottom of each set of sliding tubes 311, and a limit ring 316 is installed on the other end of each set of second compression springs 315. A set of sleeves 317 is fitted onto the outer wall of each set of sliding tubes 311, and two sets of magnetic blocks 318 are symmetrically installed on the outer wall of each set of sleeves 317. An electric ball valve 319 is installed at the bottom of each set of sleeves 317, and a processing cavity 320 is opened within each set of sleeves 317. Several sets of water injection pipes 321 are evenly spaced on the outer wall of the sleeve pipe 317. Each set of water injection pipes 321 has an insulating gauze 322 installed at one end. Each set of insulating gauze 322 is installed on the outer wall of the sleeve pipe 317. Two sets of cold air pipes 323 are symmetrically connected to the inner wall of each set of sleeve pipes 317. Each set of cold air pipes 323 is connected to the processing chamber 320. Two sets of fourth electric push rods 324 are symmetrically installed on the top inner wall of each set of sleeve pipes 317. An oil-absorbing pad 325 is connected between the output ends of the two sets of fourth electric push rods 324. The outer wall of the oil-absorbing pad 325 is slidably connected to the processing chamber 320. Two sets of sliding push rods 326 are slidably connected to the outer wall of each set of sleeve pipes 317.Each set of sleeve pipes 317 has a set of quartz sand filter layers 327 installed on its bottom inner wall.

[0029] The chain plate automatic feeder is connected to the input end of the crushing box structure 4. The kitchen waste in the residential waste transfer station enters the crushing box structure 4 through the feeder for crushing. The crushed kitchen waste enters the pretreatment box 301 and is located on the top of the top plate 205. The crushed kitchen waste contains ferromagnetic metal impurities, plastic particles and grease, and needs to be pretreated before it can be processed.

[0030] The first motor 305 is started to drive the pressure plate 306 to rotate, so that one end of the two pressure plates 306 abuts against the inner wall of the sliding frame 304, and the pressure sensors 307 on the other end squeeze each other to ensure the sealing between the two pressure plates 306, which is more conducive to the subsequent compression work. First, the third electric push rod 309 in the vacuum tube 308 is started to push the magnetic blocks 318 into the kitchen waste. Then, the second motor 310 is started to drive the sleeve pipe 317 to rotate. While the sleeve pipe 317 is rotating, it drives the magnetic blocks 318 to stir at a uniform speed in the kitchen waste, adsorbing the ferromagnetic metal impurities in the kitchen waste. The third electric push rod 309 drives the magnetic blocks 318 to move up and down to ensure the adsorption range, which improves the adsorption effect of ferromagnetic metal impurities in the kitchen waste and improves the stirring effect of the kitchen waste.

[0031] After the ferromagnetic metal impurities are adsorbed, the third electric push rod 309 is activated, causing the top of the sliding tube 311 to adhere to the bottom of the vacuum tube 308. Subsequently, the second electric push rod 303 is activated, causing the sliding frame 304 to descend. As the sliding frame 304 descends, it drives the two sets of pressure plates 306 to squeeze the kitchen waste. During the squeezing process, wastewater enters the sleeve pipe 317 through the water injection pipe 321 and is separated from impurities by the insulating gauze 322. As the sliding frame 304 descends, it also drives the sliding tube 311 to the sleeve pipe. The sliding tube 311 slides within the tube 317, squeezing wastewater into the treatment chamber 320 as it slides. As the water level in the treatment chamber 320 rises, floating debris rises to the surface. During this sliding process, the sliding tube 311 begins to compress the second compression spring 315. Upon reaching the treatment chamber 320, the two sets of first compression springs 313 sense the pressure disappearing and begin to cause the two sets of limit blocks 314 to rebound. During this rebound, the two sets of limit blocks 314 abut against the bottom of the inner wall of the sleeve tube 317, thus isolating the inner wall of the sleeve tube. This causes wastewater to accumulate in the treatment tank. When it is necessary to disengage the limiting block 314, simply push the sliding push rod 326 to push the limiting block 314. After the limiting block 314 retracts into the sliding cavity, the second compression spring 315 senses the pressure disappearing, thereby causing the sliding tube 311 to rise within the sleeve pipe 317. At this time, the output end of the condenser structure 312 on the sliding tube 311 and the input end of the cold air pipe 323 are at the same height. Grease and floating impurities begin to rise to the water surface, activating the condenser structure 312. Cooling air is introduced into the processing chamber 320 through the cooling air pipe 323. The cooling air naturally descends, causing the grease to begin to accumulate and condense. Then, the fourth electric push rod 324 is activated to push the oil-absorbing pad 325 to adsorb the condensed grease impurities. Subsequently, during the drainage process, the residual grease is adsorbed through the quartz sand filter layer. When the oily wastewater passes through the quartz sand filter layer, larger oil droplets and suspended particles are trapped on the surface or in the pores of the sand layer. The buoyancy improves the adsorption effect of grease and floating impurities, while also improving the pretreatment effect of kitchen waste.

[0032] For example, such as Figure 8 and Figure 9As shown, the mechanical gripping assembly 6 includes a first electric slide 601. One end of the first electric slide 601 is mounted on a side wall of the push box 1. A transmission plate 602 is drivenly connected to the output end of the first electric slide 601. A layered box 603 is mounted on the other end of the first electric slide 601. A robotic arm structure 604 is mounted on the top edge of the transmission plate 602. A support frame 605 is mounted on the top of the transmission plate 602. A second electric slide 606 is mounted on a side wall of the support frame 605. A fifth electric push rod 607 is drivenly connected to the output end of the second electric slide 606. A third motor 608 is installed on the output end of the rod 607. A disc body 609 is driven to the output end of the third motor 608. A fixed disk 610 is installed on the bottom of the disc body 609. A metal detector 611 is installed on the bottom of the fixed disk 610. Several sets of sixth electric push rods 612 are distributed in a ring array on the outer wall of the fixed disk 610. A set of mounting blocks 613 is installed on the output end of each set of sixth electric push rods 612. A set of vibration motors 614 is installed on the bottom of each set of mounting blocks 613. A set of stirring probes 615 is driven to the output end of each set of vibration motors 614.

[0033] Kitchen waste enters the push box 1. The second electric slide 606 is activated, which moves the disc body 609 to directly above the kitchen waste. The fifth electric push rod 607 is activated, which moves several sets of stirring probes 615 into the kitchen waste. Then, the third motor 608 is activated, which drives the disc body 609 to rotate. While rotating, the stirring probes 615 stir and flatten the kitchen waste. The vibration motor 614 is activated, which drives the stirring probes 615 to vibrate. During this process, the sixth electric push rod 612 is activated, which drives the stirring probes 615 to adjust and stir. The metal detector 611 detects residual ferromagnetic metal impurities. Then, the first electric slide 601 is activated, which drives the robotic arm structure 604 to grab the ferromagnetic metal impurities and plastic particles separately and put them into the layered box 603. Finally, the kitchen waste is pushed into the biological deodorization box 5. This process improves both the stirring and crushing effect and the particle picking effect.

[0034] The rise in water level in the treatment chamber 320 causes floating debris to rise to the surface. At this time, the output end of the condenser structure 312 on the sliding tube 311 and the input end of the cold air pipe 323 are at the same height. Grease and floating debris begin to rise to the water surface. The condenser structure 312 is activated to input cold air into the treatment chamber 320 through the cold air pipe 323. The cold air naturally descends, causing grease to begin to accumulate and condense. Then, the fourth electric push rod 324 is activated to push the oil-absorbing pad layer 325 to adsorb the condensed grease and debris. Subsequently, during the drainage process, the residual grease is adsorbed through the quartz sand filter layer. The buoyancy improves the adsorption effect of grease and floating debris, while also improving the pretreatment effect of kitchen waste.

[0035] The first motor 305 is started to drive the pressure plate 306 to rotate, so that one end of the two pressure plates 306 abuts against the inner wall of the sliding frame 304, and the pressure sensors 307 on the other end squeeze each other to ensure the sealing between the two pressure plates 306, which is more conducive to the subsequent compression work. First, the third electric push rod 309 in the vacuum tube 308 is started to push several magnetic blocks 318 into the kitchen waste. Then, the second motor 310 is started to drive the sleeve pipe 317 to rotate. While the sleeve pipe 317 is rotating, it drives several magnetic blocks 318 to stir at a uniform speed in the kitchen waste, adsorbing the ferromagnetic metal impurities in the kitchen waste. The third electric push rod 309 drives several magnetic blocks 318 to move up and down to ensure the adsorption range, which improves the adsorption effect of ferromagnetic metal impurities in the kitchen waste and improves the stirring effect of the kitchen waste.

[0036] When the kitchen waste is processed, the first electric push rod 203 is activated to move the push plate 204 towards the end near the recycling bin 206. At this time, the kitchen waste falls onto the bottom inner wall of the transfer box 201. Then, the first electric push rod 203 is activated again to push the push plate 204 and move the kitchen waste into the push box 1. At this time, the recycling bin 206 is located directly below several sets of connecting pipes 317. The electric ball valve 319 is opened to allow water filtered by quartz sand to flow into the recycling bin 206. At this time, the magnetic block 318 is deactivated, allowing the adsorbed ferromagnetic metal impurities to fall naturally into the filter screen on the inner wall of the recycling bin 206 for recycling. During the subsequent operation of the recycling bin, its top is slidably connected to the top inner wall of the transfer box 201, which improves the sealing effect of impurity recycling in the recycling bin.

[0037] The kitchen waste is pushed onto the push box 1. The second electric slide 606 is activated, which moves the disc body 609 to directly above the kitchen waste. The fifth electric push rod 607 is activated, which moves several sets of stirring probes 615 into the kitchen waste. Then, the third motor 608 is activated, which rotates the disc body 609. While rotating, the stirring probes 615 stir and flatten the kitchen waste. The vibration motor 614 is activated, which moves the stirring probes 615 to vibrate. During this process, the sixth electric push rod 612 is activated, which moves the stirring probes 615 to adjust and stir. The metal detector 611 detects residual ferromagnetic metal impurities. Then, the first electric slide 601 is activated, which moves the robotic arm structure 604 to grab the ferromagnetic metal impurities and plastic particles separately and put them into the layered box 603. Finally, the kitchen waste is pushed into the biological deodorization box 5. This process improves both the stirring and crushing effect and the particle picking effect.
