Description

Technical Field

[0001] The invention belongs to the technical field of garbage classification and processing, and in particular relates to an intelligent garbage sorting system. Background Art

[0002] The continuous progress of garbage sorting technology has promoted the development of the industry. In recent years, with the development of digital technology and electronic technology, garbage sorting technology has made significant progress. For example, the application of technologies such as robot sorting systems, intelligent radio frequency identification systems, and intelligent camera systems has made the garbage sorting process more automated and efficient. In addition, the introduction of big data analysis technology and biometric technology has also brought new development opportunities to the garbage sorting industry. However, the equipment used in the above technologies is high-cost, easy to damage, and difficult to maintain, and has low practicality in garbage sorting work.

[0003] Although there are garbage sorting equipment on the market, including chain conveyors, bag breakers, magnetic separators, pulverizers, etc., the various machines have not formed a good assembly line operation, the overall structure is complex, the area occupied is large, and the sorting / classification of garbage is relatively rough. Therefore, it is necessary to transform the current garbage sorting equipment to realize the functions of intelligent assembly line operation, sorting and subdivision, and durability. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the present invention invents an intelligent garbage sorting system.

[0005] In order to achieve the above object, the present invention adopts the following technical solution: The intelligent garbage sorting system comprises a discharge platform, a chain conveyor, a bag breaker, a magnetic separator, a roller screen, a belt screen and a winnowing machine. The chain conveyor is divided into a lower horizontal conveying section, a lifting conveying section and an upper horizontal conveying section. A feed port is provided on the lower horizontal conveying section, and the discharge platform is arranged beside the feed port; the bag breaker is arranged on the lifting conveying section; a magnetic separator is arranged above the upper horizontal conveying section; the roller screen is arranged below the front end of the upper horizontal conveying section; the end of the roller screen in the conveying direction is connected to a belt screen inclined upward; and the end of the belt screen in the conveying direction is connected to a winnowing machine.

[0006] The innovation of the present invention is to combine the unloading platform, chain conveyor, bag breaker, magnetic separator, roller screen, belt screen and air separator into a whole in an assembly line operation mode, so as to achieve the functions of high mechanical utilization and precise sorting and segmentation, and does not adopt high-end technology, has low maintenance cost and strong durability.

[0007] Furthermore, the lower horizontal conveying section is arranged under the ground, so that the unloading platform can be directly arranged on the ground without building a high platform to install the unloading platform, thus reducing the cost investment and facilitating the connection between the garbage truck and the unloading platform.

[0008] Furthermore, it also includes a water collection tank and a first deodorizing device, which are arranged at the bottom of the unloading platform. The water collection tank is used to collect the residual liquid of the garbage dumped into the feed port, and the first deodorizing device is used to spray the garbage in the feed port with disinfectant and deodorizing liquid to maintain the hygiene of the production environment.

[0009] Furthermore, it also includes a belt conveyor and a protective cover. The belt conveyor is arranged at the bottom of the roller screen. A protective cover is arranged between the belt conveyor and the roller screen to transport and collect a small amount of heavy inorganic garbage and a large amount of organic garbage falling into the gap between the rollers of the roller screen.

[0010] Furthermore, the installation inclination angle of the belt screen is 50~55 degrees. The heavier garbage and bottles and cans roll down along the belt screen into the storage bin due to the inclination angle and their own weight. After simple sorting, they can be directly utilized as resources. The light garbage is transported upward along the belt screen into the air separator.

[0011] Furthermore, the air separator includes a machine frame, a fan, a partition and a sorting roller. The interior of the machine frame is divided into a sorting bin and a light object storage bin by the vertically arranged partition and the horizontally arranged sorting roller. The top of the sorting bin is open. The fan is arranged on the side opposite to the sorting bin and the light object storage bin. The air outlet of the fan is higher than the installation position of the sorting roller. The relatively light light garbage falling from the top will be blown into the sorting roller for cutting and crushing and enter the light object storage bin, while the relatively heavy light garbage will directly enter the sorting bin, thereby realizing the further subdivision of the light garbage.

[0012] Furthermore, it also includes a dust hood and a connecting pipe. The top of the light object storage bin is provided with a dust hood, and the dust hood is connected to the air inlet of the fan through the connecting pipe, so that air circulation is formed in the frame to avoid air selection failure caused by excessive internal air pressure.

[0013] Furthermore, a filter is provided in the dust removal cover to filter dust blown away from the garbage to avoid environmental pollution.

[0014] Furthermore, it also includes a second deodorizing device. The top of the light object storage bin is provided with a second deodorizing device to deodorize the light garbage and create a good environment for the staff.

[0015] The advantages of the present invention are: 1. The technical solution of the present invention integrates the unloading platform, chain conveyor, bag breaker, magnetic separator, roller screen, belt screen and air separator into a whole by means of assembly line operation, so as to realize multiple and subdivided sorting of garbage, and can intelligently sort out high-value recycled garbage (such as paper, plastic, ferromagnetic metal, fabric, glass, etc.) and low-value recycled garbage; 2. The entire sorting system is a purely mechanical structure without high-precision equipment, and has the characteristics of low use cost, simple maintenance and long service life.

DETAILED DESCRIPTION

[0017] The present invention is described in detail below with reference to the accompanying drawings: In the description of the present invention, it should be noted that the directions or positional relationships indicated by “upper”, “lower”, “horizontal”, “vertical”, etc. are based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the product of the invention is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, and a specific direction structure and operation, and therefore cannot be understood as a limitation on the present invention.

[0018] like Figure 1-5As shown, the intelligent garbage sorting system includes a discharge platform 1, a chain conveyor 2, a bag breaker 3, a magnetic separator 4, a roller screen 5, a belt screen 6 and a winnowing machine 7. The chain conveyor 2 is divided into a lower horizontal conveying section 21, a lifting conveying section 22 and an upper horizontal conveying section 23. A feed port 24 is provided on the lower horizontal conveying section 21. The feed port 24 is used to receive garbage dumped from the discharge platform 1. In order to make the feed port 24 more reasonably matched with the discharge platform 1, the lower horizontal conveying section 21 is arranged under the ground. The unloading platform 1 is arranged next to the feed port 24, and a water collecting tank and a first deodorizing device are arranged at the bottom of the unloading platform 1. The water collecting tank is used to receive the liquid contained in the garbage to prevent the smelly liquid from flowing and polluting the floor. A drain pipe is connected to the bottom of the water collecting tank, and the collected liquid can be discharged into the sedimentation tank for purification; the first deodorizing device is arranged next to the water collecting tank, and the first deodorizing device includes a liquid storage tank, a water pump and a nozzle. The liquid storage tank is used to hold deodorant and disinfectant, and the water pump is used to pump the deodorant and disinfectant into the nozzle. The nozzle is arranged on the unloading platform and the water collecting tank, and the disinfectant and deodorizing liquid can be sprayed regularly to maintain the hygiene of the production environment, ensure the health of employees, and avoid the breeding of germs and the generation of infectious sources.

[0019] The bag breaker 3 is arranged on the lifting conveying section 22. The bag breaker 3 breaks the garbage bag through the barbed roller to separate and scatter the garbage. The barbed roller is made of high-strength alloy tool steel, which is sturdy and durable. A magnetic separator 4 is arranged above the upper horizontal conveying section 23. The magnetic separator 4 is composed of an electromagnetic iron remover, a frame, a driving motor, an iron unloading belt, a transmission roller, a roller, a sprocket, a baffle, a hanging ring, a bearing, a bearing shell and other components. The working principle is that when the transported garbage passes through the strong magnetic field of the electromagnetic iron remover, the iron and magnetic substances mixed in the material are firmly adsorbed on the iron unloading belt under the action of the strong magnetic attraction of the iron remover. At the same time, the driving motor drives the belt to run and throws the ferromagnetic substances out of the site, thereby achieving the purpose of iron removal.

[0020] The roller screen 5 is arranged below the front end of the upper horizontal conveying section 23, and the garbage after iron removal falls directly onto the roller screen 5. The roller screen 5 is composed of a motor, a reducer, a bevel gear reducer, a screen shaft and a screen plate. Each screen shaft is equipped with several special-shaped screen plates with good wear resistance. The screen plates on the adjacent two screen shafts are arranged in a staggered manner to form a rolling screen surface. Its working principle is that after the garbage enters the roller screen 5, it moves forward along the screen surface, and at the same time, the screen shaft stirs and breaks up the garbage, and the garbage (mainly organic garbage) smaller than the gap between the screen shaft or the screen plate falls, and large pieces of materials such as paper, cloth, and plastic are driven forward by the roller and the screen plate to complete the screening. The screen surface in the roller screen is set at a small angle of 5 to 10 degrees to the flow direction of the garbage flowing in from the chain conveyor 2. In this way, the garbage flowing into the roller screen 5 will not directly impact the screen surface vertically, and the garbage flow is more reasonable and smoother. At the same time, the impact of the inlet garbage on the screen plate and the screen shaft is small, and the block garbage is not easy to get stuck between the screen shafts. The screening efficiency is higher, the operation is more reliable, and less downtime for maintenance is required.

[0021] A belt conveyor 8 is provided at the bottom of the roller screen 5, and the garbage falling from the screen shaft or the gap of the screen plate is directly conveyed to the corresponding storage box for temporary storage. In order to avoid the organic garbage from emitting bad smell and reducing the time of falling, a protective cover 9 is provided between the belt conveyor 8 and the roller screen 5.

[0022] The end of the roller screen 5 in the conveying direction is connected with a belt screen 6 inclined upward, and the inclination angle of the belt screen 6 is 50-55 degrees. By controlling the inclination angle, the heavy objects and bottles and cans on the screen that fall from the roller screen to the belt screen 6 can be separated. The heavy objects and bottles and cans will fall back to the lowest point of the belt screen 6 under the action of their gravity and the inclination angle and enter the collection box.

[0023] At the end of the belt screen 6 in the conveying direction, a wind separator 7 is connected. Light garbage (including plastic pieces, cloth pieces, paper pieces, etc.) screened from the belt screen 6 will enter the wind separator 7 for further sorting. The wind separator 7 includes a machine frame 71, a fan 72, a partition 73, a sorting roller 74, a dust cover 77, a connecting pipe 78 and a second deodorizing device 79. The interior of the machine frame 71 is divided into a sorting bin 75 and a light object storage bin 76 by a vertically arranged partition 73 and a horizontally arranged sorting roller 74. The light object storage bin 76 is in the shape of a "7". The vertical section is used to store heavier light garbage, and the horizontal section is used to wind select lighter light garbage. The top of the sorting bin 75 is open, and the opening is directly aligned with the drop of the belt screen 6. The fan 72 is arranged on the side opposite to the sorting bin 75 and the light object storage bin 76. The air outlet of the fan 72 is higher than the installation position of the sorting roller 4. The wind of the fan 72 blows directly from the light object storage bin 76 to the sorting bin 75. The heavier light garbage falls directly into the light object storage bin 76. The lighter light garbage is blown to the sorting bin 75 and falls on the sorting roller 74, and then cut and pressed into the sorting bin 75. In order to prevent the dust in the garbage from being scattered and the odor from being emitted when the wind blows, a dust cover 77 is arranged on the top of the light object storage bin 77 (the top of the frame 71). The dust cover 77 is connected to the air inlet of the fan 72 through a connecting pipe 78, so that the wind in the frame 71 is circulated and used to avoid excessive internal air pressure. A filter is arranged in the dust cover 77 to filter the dust scattered from the garbage. In order to ensure a clean environment, a second deodorizing device 79 is provided on the top of the light object storage bin 77 , and the second deodorizing device 79 sprays a deodorant into the machine frame 71 .

[0024] In this embodiment, in order to ensure the cleanliness and odorlessness of the working environment of personnel, the chain conveyor 2, roller screen 5, belt screen 6 and winnowing machine 7 and the connection points between them are sealed, and each device is controlled by the control box to complete the garbage segmentation. At the garbage shedding point of each device, a corresponding collection box will be set to collect the corresponding sorted garbage.

[0025] The working principle of the garbage sorting system of the present invention is as follows: the garbage is first discharged through the unloading platform 1 and enters the chain conveyor 2 to break the bag and the iron products in the garbage are sorted out through the magnetic separator 4. The remaining garbage enters the roller screen 5 to sort out the organic garbage. Finally, the remaining garbage enters the belt screen 6 to be sorted again into bottles / heavier garbage and light garbage. The light garbage enters the wind separator 7 to be sorted into light garbage (paper, plastic sheets and cloth sheets) and lighter garbage. The garbage sorted out in each step can be directly recycled or transported to the franchise unit for receipt after simple sorting.

[0026] Although the specific embodiments of the present invention have been described and illustrated in detail above, it should be noted that various changes and modifications may be made to the above embodiments without departing from the spirit of the present invention and the scope of the appended claims.
