Description

Technical Field

[0001] The invention belongs to the field of radioactive waste sorting equipment, and in particular relates to a waste sorting glove box and a waste sorting method thereof in the field. Background Art

[0002] Solid radioactive waste is a major type of radioactive waste, and nuclear facility operators should transfer solid radioactive waste. For safety, technical and financial reasons, it is necessary to pre-treat it before disposal, such as eliminating or reducing the radioactive, physical, chemical and biological hazards associated with the waste and reducing the volume of the waste to reduce the cost of transportation and disposal. Therefore, timely reduction and conditioning of the waste is a critical step.

[0003] At present, many wastes can be treated for a second time before temporary storage, which can further reduce the volume. Since secondary treatment has certain requirements on the composition of waste, some current treatment methods make it impossible to carry out secondary treatment of waste, which limits the implementation of further volume reduction of waste. At the same time, considering resource recycling, a large part of the waste is contaminated metal materials, and most of them have low radioactivity levels. If they are mixed with other wastes for treatment, they will not be able to be recycled. At present, the waste sorting process adopts manual operation, which is inefficient. Therefore, too many people are invested in a sorting line, and the labor cost is high. However, if all intelligent production lines are used in this link, the process is too complicated and the investment consumption is too large, which is not worth the loss. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a waste sorting glove box and a waste sorting method thereof.

[0005] The present invention adopts the following technical solution:

[0006] A waste sorting glove box, the improvement of which lies in: comprising a base assembly, the back of the base assembly is parallel to a roller conveyor line, one end of a chain of a lifting chain conveyor is placed between rollers of the roller conveyor line and is parallel to the rollers, the other end of the chain extends into the base assembly, the front of the base assembly is a lifting operating table, the top of the base assembly is a sorting bin assembly, a transition bin assembly and a flip feed assembly are arranged in sequence on the side of the sorting bin assembly, and a control operating table assembly for controlling the work of the above-mentioned parts is also arranged.

[0007] Furthermore, the front of the base assembly is closed, and the top and back are open. A fastening interface is arranged on the back of the base assembly. A magnetic induction proximity switch and a group of barrel holding blocks are arranged in the fastening interface. The group of barrel holding blocks includes two blocks with adjustable extension.

[0008] Furthermore, the roller conveyor line includes a roller frame, on which several rollers are installed. Side baffles are installed on the sides of each roller. Slots for the chain lifting of the lifting chain conveyor are reserved on the roller frame and the side baffles. A magnetic induction switch and two groups of photoelectric pair switches are also installed on the side baffle opposite to the lifting chain conveyor. Each roller is driven by a roller motor through a single-sided double chain. Several legs are arranged at the bottom of the roller frame, and the bottom of each leg is connected to the floor plate through an adjustable foot.

[0009] Furthermore, the spacing between adjacent rollers is designed according to the size of the steel drum to ensure that there are at least three rollers supporting the steel drum at any time.

[0010] Furthermore, the lifting chain conveyor includes a chain conveying surface, and a jacking device is arranged on each of the two bottom sides of the chain conveying surface. The chain conveying surface includes two rows of chains and a driving motor. The driving motor drives the two rows of chains to move bidirectionally through a multi-stage transmission shaft. A chain tension adjustment device is also arranged at one end of the chain conveying surface. The jacking device includes a support platform. The bottom of the support platform is an adjustable leg, and the top is a guide post. A lifting cylinder with a magnetic switch is also installed on the support platform.

[0011] Furthermore, both rows of chains are self-lubricating and maintenance-free chains, and anti-slip patches are fixed on the top of each row of chains. The length of the anti-slip patches is equivalent to the width of the roller conveyor line, and the part of the chain with the anti-slip patch always remains horizontal.

[0012] Furthermore, electric lifting floor feet with a lead screw structure or a scissor structure are designed inside both ends of the lifting operation platform.

[0013] Furthermore, the sorting bin assembly internally includes several workstations, which are connected by a conveyor track. The conveyor track starts from the input end of the sorting bin assembly and is driven by a three-phase motor outside the sorting bin assembly box. A tool support component is arranged on the top of each workstation, a glove hole with a rubber glove is arranged on the front, and several waste bin interfaces with covers are arranged at the bottom. And each cover is equipped with a cover lifting component. The cover lifting component includes a cover lifting cylinder installed outside the sorting bin assembly box and a shaft hole installed on the inner wall of the box. The middle of the support rod is hinged on the shaft hole. The head of the support rod is inside the box and is fixed to the cover. The tail of the support rod is outside the box and is hinged to the cylinder push rod of the cover lifting cylinder. A telescopic sealing cover component is arranged at the bottom of each waste bin interface.

[0014] Furthermore, the tool support component adopts a "Z"-shaped structure. When in use, the pneumatic telescopic rod of the tool support component is pulled down to lower the table surface, and when not in use, the pneumatic telescopic rod retracts.

[0015] Further, the telescopic sealing cover component includes a feeding pipe connected to the bottom of the waste bin interface. A fixing plate is sleeved outside the feeding pipe. Four sealing cylinders with push rods downward are installed around the feeding pipe on the fixing plate. Each of the four corners of the interface plate is installed on the push rods of the above four sealing cylinders through a floating joint. A hole is opened in the center of the interface plate. The diameter of this hole is smaller than the inner diameter of the steel barrel, and a sealing rubber ring is arranged around the lower part of the hole. The feeding pipe is connected to the upper part of this hole through a section of corrugated pipe.

[0016] Further, the sorting bin assembly internally includes three workstations. A waste bin interface with a cover plate is provided at the bottom of two of the workstations, and two waste bin interfaces with cover plates are provided at the bottom of the other workstation. Four fastening interfaces are provided on the back of the base assembly, respectively located under the above four waste bin interfaces. It also includes four lifting chain conveyors corresponding to the above four fastening interfaces respectively. There are two roller conveyor lines, and the two roller conveyor lines are connected in series end to end.

[0017] Further, the installation method of the transition bin assembly is adjustable floor feet and main body welding. One side of the transition bin assembly is a sloping feed inlet, and the other side is an irregular pneumatic shielding door, which is docked with the input end of the sorting bin assembly. The front of the transition bin assembly is a glass viewing window and a glove hole with rubber gloves. The back is a maintenance door. The top of the transition bin assembly is an LED lighting strip and its protective cover. The internal tray of the transition bin assembly is divided into two layers. The upper tray is reserved with a liquid receiving hole, and the lower tray is connected to the liquid receiving pipe arranged along the base assembly. The liquid receiving pipe finally communicates with the waste liquid receiving tank.

[0018] Further, the flipping feeding component includes a gantry bracket and a flipping plate surface. The gantry bracket is installed with floor feet. A feed inlet is provided on the flipping plate surface, and a sealing cover is connected between the flipping plate surface and the sloping feed inlet of the transition bin assembly. The feed inlet is covered in the sealing cover. Both ends of the sealing cover are respectively tightened and pressed on the metal frames of the flipping plate surface and the sloping feed inlet of the transition bin assembly through a flange plate.

[0019] Further, the control console component includes a display support box, and a control system is integrated in the control console component and the lifting console.

[0020] A waste sorting method uses the above-mentioned waste sorting glove box, and the improvement lies in:

[0021] Before feeding, the pneumatic shielding door of the transition bin assembly is closed, and the cover plates of the four waste bin interfaces of the sorting bin assembly are closed. The sorting bin assembly is in a sealed state and not connected to the outside.

[0022] The heights of the two rows of chains of the lifting chain conveyor are default lower than the heights of the rollers in the roller conveyor line. Start the roller motors in the roller conveyor line to drive the rollers to rotate and drive the steel drum to slide forward. When the steel drum slides above the corresponding lifting chain conveyor, it triggers two sets of photoelectric opposed switches, and then turn off the roller motors in the roller conveyor line to stop the rotation of the rollers. At this time, the steel drum is exactly located at the center of the two rows of chains;

[0023] The lifting cylinders in the two lifting devices of the lifting chain conveyor rise synchronously, causing the two rows of chains to rise from between the rollers and lift the steel drum from the rollers in the roller conveyor line. After that, the heights of the two lifting devices remain unchanged. Then start the drive motor to drive the two rows of chains to move and transport the steel drum to the fastening interface at the back of the base assembly. After the steel drum triggers the magnetic induction proximity switch on the fastening interface, turn off the drive motor to make the two rows of chains stop moving. The two stoppers on the fastening interface make the steel drum concentric with the feed pipe of the telescopic sealing cover component at the corresponding station of the sorting bin component. Start the four sealing cylinders of the telescopic sealing cover component, and the push rods of the four sealing cylinders move downward synchronously to dock the sealing rubber ring of the interface plate with the mouth of the steel drum;

[0024] Place the feeding steel drum on the gantry bracket of the flipping feeding component, lift the feeding steel drum so that its open end gradually docks with and compresses against the feeding port, rotate the flipping plate surface, and pour the waste in the feeding steel drum along the feeding port and the sloping feeding port into the upper tray inside the transition bin component. The waste liquid in the waste drops from the liquid receiving hole into the lower tray and finally flows into the waste liquid receiving tank through the liquid receiving pipe. After opening the pneumatic shielding door, the operator uses the glass viewing window and glove holes from the front to place the solid waste on the upper tray onto the conveyor belt inside the sorting bin component, and then it is sent to the corresponding station by the conveyor belt;

[0025] Start the cover lifting cylinder at this station to extend its cylinder push rod, pull the support rod to swing around the shaft hole to open the cover plate of the waste bucket interface. The operator uses the glove hole from the front of the station to throw the solid waste along the waste bucket interface and the feed pipe into the steel drum. After throwing, turn off the cover lifting cylinder at this station to retract its cylinder push rod, pull the support rod to swing around the shaft hole to close the cover plate of the waste bucket interface;

[0026] After the steel drum is filled with solid waste, start the drive motor of the lifting chain conveyor to drive the two rows of chains to move, and transport the steel drum to the side baffle opposite to this lifting chain conveyor on the roller conveyor line. After the steel drum triggers the magnetic induction switch on the side baffle, turn off the drive motor to make the two rows of chains stop moving. The lifting cylinders in the two lifting devices of the lifting chain conveyor descend synchronously, causing the two rows of chains to fall from between the rollers, place the steel drum on the rollers in the roller conveyor line, and then the heights of the two lifting devices remain unchanged. Start the roller motors in the roller conveyor line to drive the rollers to resume rotation and drive the steel drum to continue sliding forward, so as to send out the steel drum;

[0027] After completing all the solid waste sorting work, close the pneumatic shielding door of the transition bin assembly. Ensure that the covers of the waste bucket interfaces at each station are closed, then turn the flipping plate surface back to separate the feeding steel barrel from the feeding port, and finally lower the feeding steel barrel.

[0028] The beneficial effects of the present invention are as follows:

[0029] The waste sorting glove box disclosed by the present invention adopts a combination of automation and manual operation. The feeding, solid waste transportation, and steel barrel conveying processes are carried out automatically and can be completed with one key, while the waste sorting process is carried out manually. The effective combination of the two can improve efficiency and reduce the process complexity.

[0030] The waste sorting glove box disclosed by the present invention fully considers the requirements of scientific, safe, and efficient technical process routes. All external interfaces of the sorting bin assembly can be isolated from the outside during the sorting process to achieve full sealing, minimizing the radiation risks for the staff and the public and avoiding the generation of more additional waste during the production process.

[0031] For the waste sorting glove box disclosed by the present invention, the electrical part is placed as much as possible in the pollution-free area outside the glove box, and at the same time, maintenance doors are provided in some compartments, fully considering the safety and convenience of maintenance.

[0032] The waste sorting method disclosed by the present invention can efficiently sort radioactive waste by using the above-mentioned waste sorting glove box. Brief Description of the Drawings

Detailed implementation manners

[0051] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0052] Embodiment 1. This embodiment discloses a waste sorting glove box, which can be installed in a waste treatment plant and is used for sorting and preparing solid wastes such as radioactive combustible waste, radioactive waste resin, and radioactive non-combustible waste generated during the operation of a project. After the treatment is completed, it is compacted and put into a drum for temporary storage.

[0053] As Figure 1As shown in Figure 3, the waste sorting glove box mainly consists of two major parts: the general waste glove box 1 and the conveying system 2. The general waste glove box is mainly assembled from six components, namely the transition bin component 5, the sorting bin component 6, the base component 7, the tipping feeding component 8, the control console component 9, and the lifting console 10. It mainly sorts and classifies general waste, that is, sorts the waste in one feeding steel drum and loads it into four steel drums respectively, and ensures that the sorting bin component and the steel drums are isolated from the external environment during the entire feeding, sorting, discharging, and barrel unloading processes. The conveying system mainly consists of two roller conveyor lines 3 arranged in series and four lifting chain conveyors 4 arranged perpendicular to the roller conveyor lines, and is used to complete the barrel loading, conveying, and unloading of the steel drums.

[0054] The general waste glove box is arranged on one side of the conveying system. The sorting production line in the sorting bin component is parallel to the roller conveyor line, and the vertical conveying of the steel drum between the general waste glove box and the roller conveyor line is realized through the lifting chain conveyor.

[0055] Specifically, the back of the base component is parallel to the roller conveyor line. One end of the chain of the lifting chain conveyor is placed between the rollers of the roller conveyor line and is parallel to the rollers, and the other end of the chain extends into the base component. Since a part of the lifting chain conveyor is embedded (i.e., placed as described above) in the roller conveyor line, and the space under the roller conveyor line is very limited, the layout of a single lifting chain conveyor is designed in cooperation with the roller conveyor line, which not only ensures that it is embedded between the rollers of the roller conveyor line, but also does not affect the safe horizontal conveying of the steel drum due to eccentric design.

[0056] The front of the base component is the lifting console, the top of the base component is the sorting bin component, the transition bin component and the tipping feeding component are sequentially arranged on the side of the sorting bin component, and in addition, a control console component for controlling the work of each of the above parts is also provided.

[0057] As Figure 4 shown, the base component is mainly used for supporting the sorting bin component and providing the installation and conveying space for the lifting chain conveyor and the steel drum. The front of the base component is closed, the top and the back are open, and a fastening interface 39 connected to the lifting chain conveyor is provided on the back of the base component to position the lifting chain conveyor, so that the bucket stopping position of the lifting chain conveyor is concentric with the feeding pipe, and the lifting chain conveyor and the feeding pipe are on the same center line. A magnetic induction proximity switch 40 and a set of bucket holding blocks are arranged in the fastening interface. The set of bucket holding blocks includes two blocks 41 with adjustable elongation.

[0058] As Figure 5As shown in FIGS. 6 - 7, the roller conveyor line is made of a carbon steel main body and straight rollers, and includes a roller frame 42. A number of rollers 45 are installed on the roller frame. The spacing between adjacent rollers is designed according to the size of the steel drum to ensure that there are no less than three rollers supporting the steel drum at any time. Side baffles 46 are installed on the sides of each roller. Slots 58 for the chain lifting of the lifting chain conveyor are reserved on the roller frame and the side baffles. A magnetic induction switch 59 and two groups of photoelectric opposed switches 60 are also installed on the side baffle opposite to the lifting chain conveyor. The two groups of photoelectric opposed switches are used to turn off the roller motors in the roller conveyor line, so that the steel drum stops at the center position between the two rows of chains of the lifting chain conveyor. Each roller is driven by a roller motor 47 through a single - side double - chain drive (only the single - side chain drive can ensure the use of the lifting chain conveyor, and the chain is not shown in Figure 5 . The overall positioning of the roller conveyor line adopts the method of anchor plates plus expansion bolts. A number of legs 44 are provided at the bottom of the roller frame. The bottom of each leg is connected to the anchor plate 48 through an adjustable foot 43. First, fix the anchor plate to the ground through expansion bolts according to the layout, then adjust the position and height on the anchor plate. After finally confirming the position, weld the adjustable foot to the anchor plate for positioning. This method can solve the influence of space limitation.

[0059] As Figure 6 shown, since the lifting chain conveyor needs to lift and should not affect the movement of the steel drum on the roller conveyor line at the lowest position, the lifting chain conveyor should be lower than the height of the roller conveyor line at the lowest position. Therefore, slots 58 for the chain lifting of the lifting chain conveyor are reserved on the roller frame and the side baffles on the side of the roller conveyor line, so that when the lifting chain conveyor drops to the lowest position, it will not interfere with the rollers or other components of the roller conveyor line. The position and height of the roller conveyor line on the side close to the base assembly also need to be arranged according to the distance between the center of the blanking pipe of the telescopic sealing cover component and the lifting chain conveyor at the corresponding station.

[0060] As Figure 8 shown, the lifting chain conveyor includes a chain conveying surface 50. A jacking device 49 is provided on each of the two bottom sides of the chain conveying surface. The chain conveying surface includes two rows of chains 55 and a drive motor 56. The drive motor drives the two rows of chains to move bidirectionally through a multi - stage transmission shaft. The two rows of chains can ensure that the contact surface with the bottom of the steel drum is sufficient and the friction force is large enough. A chain tension adjusting device 57 is also provided at one end of the chain conveying surface to facilitate the installation and replacement of the chain and adjust the tension.

[0061] The lifting device includes a support platform 52, with adjustable legs 54 at the bottom of the support platform and a guide post 51 at the top. A lifting cylinder 53 with a magnetic switch is also installed on the support platform. The lifting device uses the synchronous action of two electric lifting cylinders in the lower layer to achieve precise lifting of the chain conveyor surface, and uses the magnetic switch of the lifting cylinder to detect the in-place lifting of the chain conveyor surface. Thus, when at the lowest position, it does not affect the transportation of the conveying surface of the roller conveyor line, and when at the highest position, it can lift the steel drum above and move the steel drum to the corresponding work station.

[0062] Both rows of chains are self-lubricating and maintenance-free chains, avoiding the application of lubricating oil. And a long anti-slip patch is fixed at the top of each row of chains, and the length of the anti-slip patch is equivalent to the width of the roller conveyor line.

[0063] The two rows of chains moving forward can transport the steel drum to the fastening interface on the back of the base assembly, and moving backward can transport the steel drum to the side baffle of the roller conveyor line opposite to this lifting chain conveyor. During this process, the part of the chain with the anti-slip patch is always under the steel drum and remains horizontal, and will not be involved in the gear to produce bending and wrinkles.

[0064] The lifting chain conveyor realizes the reciprocating transportation of the steel drum between the roller conveyor line and the corresponding work station. The lifting chain conveyor itself does not have a proximity switch, but since it is responsible for feeding empty steel drums from the roller conveyor line to the corresponding work station and discharging steel drums filled with solid waste from the corresponding work station to the roller conveyor line, a magnetic induction proximity switch is set inside the fastening interface of the base assembly to turn off the drive motor to make the two rows of chains immobile when the barrel feeding is in place. Similarly, a magnetic induction switch is also arranged on the side baffle of the roller conveyor line opposite to the lifting chain conveyor (i.e., the barrel discharging end) to turn off the drive motor to make the two rows of chains immobile when the barrel discharging is in place.

[0065] Electric lifting feet with screw structures or scissor structures are designed inside both ends of the lifting operation platform, and can be modified using common lifting equipment.

[0066] As shown in Figures 9(a), 9(b), 9(c), Figure 10 As shown, the main frame of the sorting bin assembly is made of relatively thick steel plates so as to install lifting lugs at the top of the main frame, and the rest is welded with plates and fastened with fasteners. The sorting bin assembly includes several work stations inside, and each work station is penetrated by a conveying track 23. The conveying track is spliced by flexible materials. The conveying track starts from the input end of the sorting bin assembly and is driven by a single three-phase motor 27 outside the sorting bin assembly. The single three-phase motor is outside the box for easy maintenance and repair.

[0067] A tool support member 26 is provided at the top of each work station. The tool support member adopts a "Z"-shaped structure. During use, the pneumatic telescopic rod of the tool support member is manually pulled down to lower the table for placing small tools and other items in front of the operator. When not in use, the pneumatic telescopic rod retracts, providing buffering and assistance for the table to return to a higher position. A glove hole with rubber gloves is provided on the front of each work station. A number of waste bin interfaces with covers 29 are provided at the bottom of each work station, and each cover is equipped with a cover lifting member 24. The cover lifting member includes a cover lifting cylinder 28 installed outside the sorting bin assembly box and a shaft hole 30 installed on the inner wall of the box. The middle of the support rod 31 is hinged to the shaft hole. The head of the support rod is inside the box and is fixedly connected to the cover. The tail of the support rod is outside the box and is hinged to the cylinder push rod of the cover lifting cylinder (i.e., the connection between the cylinder push rod and the support rod is also rotatable). The cover lifting member realizes the opening and closing of the cover of the waste bin interface through the telescopic movement of the cylinder push rod of the cover lifting cylinder. A telescopic seal cover member 25 is provided at the bottom of each waste bin interface.

[0068] As Figure 11 shown, the telescopic seal cover member includes a blanking pipe 35 connected to the bottom of the waste bin interface. A tightening fixing plate 34 is sleeved outside the blanking pipe. Four sealing cylinders 32 with push rods downward are installed around the blanking pipe on the fixing plate. The four corners of the interface plate 33 are respectively installed on the push rods of the above four sealing cylinders through a floating joint 36. The floating joint can cope with displacements caused by uneven actions of the sealing cylinders, different lengths of the push rods extending, and uneven barrel surfaces. A hole is opened in the center of the interface plate. The diameter of this hole is smaller than the inner diameter of the steel barrel, and a sealing rubber ring 37 is arranged around the lower part of the hole to enable good sealing of the steel barrel even in the case of non-precise positioning. The blanking pipe is connected to the upper part of this hole through a corrugated pipe 38. The corrugated pipe has characteristics such as elasticity, expandability, and wear resistance. The telescopic seal cover member mainly realizes the up and down movement of the interface plate through the synchronous telescopic movement of the push rods of the four sealing cylinders. When moving downward, the central hole of the interface plate is pressed firmly on the open mouth of the steel barrel.

[0069] In this embodiment, the inside of the sorting bin assembly includes three work stations. One waste bin interface with a cover is provided at the bottom of two of the work stations, and two waste bin interfaces with covers are provided at the bottom of the other work station. Correspondingly, four fastening interfaces located under the above four waste bin interfaces are provided on the back of the base assembly. It also includes four lifting chain conveyors respectively corresponding to the above four fastening interfaces. There are two roller conveyor lines, and the two roller conveyor lines are connected in series end to end. The solid waste received on the conveyor belt of the sorting bin assembly is manually sorted and classified through the three work stations and then thrown into the steel barrels under the four waste bin interfaces.

[0070] As shown in Figures 12(a) and 12(b), the installation method of the transition bin assembly is adjustable feet and welded main body. One side of the transition bin assembly is a sloping feed inlet 16, and the other side is an irregular pneumatic shielding door 17. The pneumatic shielding door is docked with the input end of the sorting bin assembly. The front of the transition bin assembly is a glass viewing window 19 and a glove hole 20 with rubber gloves. Operators observe through the glass viewing window and operate using the rubber gloves in the glove hole. The back is a maintenance door 22 for maintenance personnel. The top of the transition bin assembly is an LED lighting strip and its protective cover 18. The light shines into the transition bin assembly through the glass plate on the top. The internal tray of the transition bin assembly is divided into two layers. The upper tray 21 is used to place the waste in the feed steel barrel and a liquid receiving hole is reserved. The lower tray is connected to the liquid receiving pipe arranged along the base assembly, and the liquid receiving pipe finally communicates with the waste liquid receiving tank.

[0071] The transition bin assembly is mainly responsible for connecting the tipping feed assembly and the sorting bin assembly. The sloping feed inlet is used to tightly fasten and compact with the feed inlet of the tipping feed assembly. The pneumatic shielding door is tightly docked with the input end of the sorting bin assembly to ensure that the pneumatic shielding door can compact and seal the connection between the two bins.

[0072] As Figure 13 shown, the tipping feed assembly includes a gantry bracket 14 and a tipping plate surface 13. The gantry bracket is installed with feet. A feed inlet 12 is set on the tipping plate surface. During the process of the gantry bracket holding and lifting the feed steel barrel 11, the open end of the feed steel barrel will gradually dock and compact with the feed inlet. As Figure 14 shown, a sealing cover 15 is connected between the tipping plate surface and the sloping feed inlet of the transition bin assembly. The feed inlet is covered by the sealing cover. Both ends of the sealing cover are respectively tightened and compacted on the metal frames of the tipping plate surface and the sloping feed inlet of the transition bin assembly through a flange plate.

[0073] Since the position of the tipping feed assembly completely depends on the installation position of the transition bin assembly, other components are installed first during the overall installation of the equipment, and finally the tipping feed assembly is assembled.

[0074] The control operation console assembly includes a display support box, which provides a control interface and buttons for this set of waste sorting glove box. The control system is integrated in the control operation console assembly and the lifting operation console, and the control system is installed inside the assembly.

[0075] This embodiment also discloses a waste sorting method, using the above waste sorting glove box, which specifically includes the following steps:

[0076] Before feeding, the pneumatic shielding door of the transition bin assembly is closed, the covers of the four waste bucket interfaces of the sorting bin assembly are closed, and the sorting bin assembly is in a sealed state and not connected to the outside.

[0077] The operator selects the starting and ending positions of the conveying system and sends the unfilled steel drums to the designated workstations through the lifting chain conveyor and roller conveyor line:

[0078] The height of the two rows of chains of the lifting chain conveyor is lower than the height of each roller in the roller conveyor line by default. The roller motor in the roller conveyor line is started to drive each roller to rotate and drive the steel drum to slide forward. When the steel drum slides to the top of the corresponding lifting chain conveyor, two sets of photoelectric switches are triggered to turn off the roller motor in the roller conveyor line, so that each roller stops rotating. At this time, the steel drum is exactly in the center of the two rows of chains;

[0079] The lifting cylinders in the two lifting devices of the lifting chain conveyor are synchronously lifted, so that the two rows of chains are lifted from between the rollers. After the steel drum is lifted from the rollers in the roller conveyor line, the heights of the two lifting devices remain unchanged. Then the drive motor is started to drive the two rows of chains to move the steel drum to the fastening interface on the back of the base assembly. After the steel drum triggers the magnetic induction proximity switch on the fastening interface, the drive motor is turned off to keep the two rows of chains immobile. The two blocks on the fastening interface make the steel drum and the discharge pipe of the telescopic sealing cover component of the corresponding station of the sorting bin assembly concentric, and the four sealing cylinders of the telescopic sealing cover component are started. The push rods of the four sealing cylinders are synchronously pushed downward to make the sealing rubber ring of the interface plate dock with the barrel mouth of the steel drum.

[0080] Put the feed steel barrel on the gantry bracket of the flip feed assembly, clamp the barrel, lift the lifting cylinder, lift the feed steel barrel so that its open mouth gradually docks with the feed port and compacts it, rotate the flip plate to make the feed port horizontal, pour the waste in the feed steel barrel along the feed port and the sloped feed port into the upper tray inside the transition bin assembly, and the waste liquid in the waste drips from the liquid receiving hole into the lower tray and finally flows to the waste liquid receiving tank through the liquid receiving pipe. After opening the pneumatic shielding door, the feed steel barrel, the transition bin assembly, and the sorting bin assembly are connected and isolated from the outside world. The operator manually empties the feed steel barrel from the front using the glass peep window and glove hole, and puts the solid waste on the upper tray on the conveyor belt in the sorting bin assembly, which is then transported to the corresponding workstation by the conveyor belt;

[0081] The cover-lifting cylinder of the station is started to extend its cylinder push rod, and the support rod is pulled to swing around the axis hole to open the cover of the waste barrel interface. The operator throws the solid waste into the steel barrel along the waste barrel interface and the discharge pipe from the front of the station through the glove hole. After throwing, the cover-lifting cylinder of the station is closed to retract its cylinder push rod, and the support rod is pulled to swing around the axis hole to close the cover of the waste barrel interface;

[0082] The operator selects the starting and ending positions of the conveying system, and sends the filled steel drums to the designated workstation or unloads them through the lifting chain conveyor and roller conveyor line:

[0083] Start the drive motor of the lifting chain conveyor to drive the two rows of chains to move, and transport the steel drum to the side baffle opposite to the roller conveyor line of the lifting chain conveyor. After the steel drum triggers the magnetic induction switch on the side baffle, turn off the drive motor to make the two rows of chains stationary. The lifting cylinders in the two lifting devices of the lifting chain conveyor descend synchronously, causing the two rows of chains to fall between the rollers. After placing the steel drum on the rollers inside the roller conveyor line, the heights of the two lifting devices remain unchanged. Start the roller motors inside the roller conveyor line to drive each roller to resume rotation and drive the steel drum to continue sliding forward, thereby sending out the steel drum;

[0084] After completing all the solid waste sorting work, close the pneumatic shielding door of the transition bin assembly, ensure that the covers of the waste bucket interfaces at each station are closed, isolate the entire sorting bin assembly from the outside, turn the flipping plate surface to separate the feeding steel drum from the feeding port, and finally lower the feeding steel drum.

The sorting bin assembly is in a sealed state and is not connected to the outside. The heights of the two rows of chains of the lifting chain conveyor are by default lower than the heights of the rollers inside the roller conveyor line. Start the roller motors inside the roller conveyor line to drive the rollers to rotate and drive the steel drum to slide forward. When the steel drum slides above the corresponding lifting chain conveyor, it triggers two groups of photoelectric pairs of light switches, and closes the roller motors inside the roller conveyor line to stop the rollers from rotating. At this time, the steel drum is exactly located at the center of the two rows of chains. The lifting cylinders in the two lifting devices of the lifting chain conveyor rise synchronously, causing the two rows of chains to rise from between the rollers. After lifting the steel drum from the rollers in the roller conveyor line, the height of the two lifting devices remains unchanged. Then, start the drive motor to drive the two rows of chains to move and transport the steel drum to the fastening interface on the back of the base assembly. After the steel drum triggers the magnetic induction proximity switch on the fastening interface, turn off the drive motor to make the two rows of chains immobile. The two stoppers on the fastening interface make the steel drum concentric with the discharge pipe of the telescopic sealing cover component at the corresponding station of the sorting bin assembly.

The liquid waste in the waste drips from the liquid receiving hole into the lower tray and finally flows into the waste liquid receiving tank through the liquid receiving pipe. After opening the pneumatic shielding door, the operator uses the glass viewing window and glove holes from the front to place the solid waste on the upper tray into the conveyor belt inside the sorting bin assembly, and then it is sent to the corresponding station by the conveyor belt; Start the cover-lifting cylinder at this station to extend its cylinder push rod, pull the support rod to swing around the shaft hole to open the cover plate of the steel drum interface. The operator uses the glove hole from the front of the station to throw the solid waste into the steel drum along the steel drum interface and the discharge pipe. After throwing, turn off the cover-lifting cylinder at this station to retract its cylinder push rod, pull the support rod to swing around the shaft hole to close the cover plate of the steel drum interface; After the steel drum is filled with solid waste, start the drive motor of the lifting chain conveyor to drive the two rows of chains to move, and transport the steel drum to the side baffle opposite to the lifting chain conveyor on the roller conveyor line. After the steel drum triggers the magnetic induction switch on the side baffle, turn off the drive motor to make the two rows of chains immobile. The lifting cylinders in the two lifting devices of the lifting chain conveyor descend synchronously, causing the two rows of chains to fall from between the rollers. After placing the steel drum on the rollers in the roller conveyor line, the height of the two lifting devices remains unchanged. Start the roller motor in the roller conveyor line to drive each roller to resume rotation and drive the steel drum to continue sliding forward, thereby sending out the steel drum; After completing all the solid waste sorting work, close the pneumatic shielding door of the transition bin assembly. Ensure that the cover plates of the steel drum interfaces at each station are closed, then turn back the flipping plate surface to separate the incoming steel drum from the feeding port, and finally lower the incoming steel drum.
