Description

Technical Field

[0001] This invention relates to the field of organic waste treatment technology, specifically a skid-mounted organic waste sorting and pretreatment system. Background Technology

[0002] Organic waste, also known as wet waste, refers to household waste containing organic matter. It comprises the decomposable organic matter in everyday household waste, primarily originating from daily life. Organic waste includes food scraps, vegetable roots and leaves, animal hooves and horns, melon rinds, fruit scraps, eggshells, fish scales, hair, plant branches and leaves, weeds, animal carcasses, and livestock manure. Organic waste is easily perishable and sometimes contains pathogenic microorganisms, posing significant health and epidemiological risks.

[0003] With the continuous development of technology, people have gradually realized the importance of the environment, so the proper handling of organic waste generated in daily life has become an important concern for contemporary people. Compared to the residential communities of urban residents, whose daily organic waste is centrally collected and disposed of at garbage stations, and then transported to waste treatment plants by garbage station managers, organic waste from rural areas is difficult to process due to its distance from treatment plants and its dispersed distribution. To address this issue, existing technologies provide waste sorting and processing systems as shown in publications 218475753U, CN218475761U, and CN218475762U. These systems utilize containers to transport waste processing equipment to designated locations in rural areas, providing a decentralized and flexible approach to processing organic waste distributed throughout the countryside.

[0004] However, the aforementioned existing technologies all generate wastewater when treating organic waste in rural areas. This wastewater contains pathogenic microorganisms from the organic waste and cannot be directly discharged into the land, otherwise it will cause pollution to the rural soil environment. Therefore, people need to treat the wastewater, which easily increases the steps and costs of waste treatment. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a skid-mounted organic waste sorting and pretreatment system. The system utilizes a first screw conveyor to directly transport organic waste into a rotary high-temperature dryer. The high temperature inside the rotary high-temperature dryer dries the waste to a moisture content of 30-40%. Simultaneously, the high temperature kills pathogenic microorganisms in the organic waste, and no wastewater is generated. This saves on the costs and steps of subsequent wastewater treatment, thus reducing the cost of waste disposal.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a skid-mounted organic waste sorting and pretreatment system, including a container, wherein multiple wheels are rotatably installed on one side of the bottom of the container;

[0007] The container is equipped with a waste treatment facility for handling organic waste.

[0008] The waste treatment facility includes a rotary high-temperature dryer located at the top front of the container. A first screw conveyor is installed at the inlet on one side of the rotary high-temperature dryer, through which organic waste enters the dryer. A shredder is installed at the outlet at the bottom of the other side of the dryer, and a second screw conveyor is connected to the bottom of the shredder. A belt conveyor is installed on the side of the second screw conveyor away from the shredder, located at the rear of the container. A briquetting box is installed at the end of the belt conveyor away from the second screw conveyor. After being dried by the rotary high-temperature dryer, the organic waste enters the shredder and is shredded. The shredded organic waste is then conveyed by the second screw conveyor and the belt conveyor into the briquetting box and compressed into blocks.

[0009] Preferably, the bottom of the rotary high-temperature dryer is fixed to the inner wall of the container by an I-beam bracket;

[0010] The top side of the rotary high-temperature dryer is connected to an exhaust pipe via a flange and bolts. The top of the exhaust pipe passes through the container and extends out of the top of the container to discharge the hot air generated when the container is drying organic waste.

[0011] Preferably, the bottom of the first screw conveyor is fixed with two support rods, and the bottom ends of the support rods are fixed to the bottom of the container interior by bolts.

[0012] Preferably, a limiting cover is fixed to the top of the side of the second screw conveyor away from the crusher and close to the belt conveyor. The limiting cover is located directly above the belt conveyor, and the organic waste conveyed by the second screw conveyor falls onto the top of the belt conveyor under the restriction of the limiting cover.

[0013] Preferably, the briquetting box has a feed inlet on the side near the belt conveyor, and an inclined platform is provided at the bottom of the feed inlet. The inclined platform is located on one side of the belt conveyor, and one end of the belt conveyor extends into the feed inlet. The briquetting box has a discharge outlet on the side away from the belt conveyor.

[0014] A third electric cylinder is fixed at the top inside the briquetting box. A pressing plate is fixed at the piston rod end inside the third electric cylinder. The pressing plate is in contact with the inner wall of the briquetting box. A rotating plate is provided at the bottom of the pressing plate. The side of the rotating plate away from the feed inlet is rotatably connected to the side wall of the container. A second electric cylinder is hinged at the middle of the bottom of the rotating plate. The bottom end of the second electric cylinder is hinged to the bottom of the container. The piston rod end inside the second electric cylinder extends and pushes the rotating plate to rotate inside the briquetting box so as to push the blocky organic waste located on the top of the rotating plate out of the discharge port.

[0015] Preferably, bamboo-joint telescopic rods are fixed at the four corners of the top of the briquetting box, and the bottom ends of the bamboo-joint telescopic rods are fixed to the four corners of the top of the extrusion plate.

[0016] Preferably, a briquetting box door is inserted inside the discharge port, and two first electric cylinders are fixed on one side of the briquetting box door, which are arranged vertically. The first electric cylinders are fixed to the outer wall of the briquetting box by a bracket.

[0017] Preferably, the bottom of the container is fixed with two support legs at the end away from the wheels to support the container on the ground.

[0018] Preferably, the container door is provided with a connecting frame at the bottom, and the connecting frame is welded to the bottom of the container away from the wheels.

[0019] Preferably, the container door is provided with a connecting frame at the bottom, and the connecting frame is welded to the bottom of the container away from the wheels.

[0020] Compared with existing technologies, the present invention provides a skid-mounted organic waste sorting and pretreatment system, which has the following advantages:

[0021] 1. By using the first screw conveyor to directly transport organic waste into the rotary high-temperature dryer, the high temperature inside the rotary high-temperature dryer dries the waste to a moisture content of 30-40%. At the same time, the high temperature kills pathogenic microorganisms in the organic waste, and no wastewater is generated. This saves the cost and steps of subsequent wastewater treatment and helps to reduce the cost of waste treatment.

[0022] 2. This invention utilizes a crusher to crush dried organic waste into fragments, which are then conveyed into a briquetting box by a second screw conveyor and a belt conveyor, where they are compressed into blocks for easy transport. The dried and crushed organic waste can be reused as fuel or feed, which is beneficial for the recycling of resources.

[0023] 3. By installing the rotary high-temperature dryer, crusher and briquetting box inside the container, and by providing rotatable wheels and support legs at the bottom of the container, the invention can be easily mounted on the back of a mobile vehicle for movement, thereby enhancing the flexibility of the invention.

[0024] Furthermore, by installing the rotary high-temperature dryer at the top inside the container, the impact of the heat generated by the rotary high-temperature dryer during operation on other equipment can be reduced by utilizing the principle of a small mass fraction of hot air.

Detailed Implementation

[0037] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0038] like Figure 1 and 2 As shown, the present invention provides a skid-mounted organic waste sorting and pretreatment system, including a container 1. Two container doors 2 with opposite rotation directions are movably connected to one side of the container 1 via hinges. The two container doors 2 are fastened together by a lock. Multiple wheels 3 are rotatably installed on one side of the bottom of the container 1. A connecting frame 5 is provided at the bottom of the container doors 2. The connecting frame 5 is welded to the bottom of the container 1 at the end away from the wheels 3. When using the present invention to process some scattered organic waste, the present invention can be fixed to the back of a trailer by the connecting frame 5, and the trailer can be used to pull the present invention to move it, so as to flexibly change the working position of the present invention.

[0039] After reaching the designated location, in order to enhance the stability of the bottom of container 1, such as... Figure 3 As shown, two support legs 4 are fixed at the bottom of the container 1 away from the wheel 3 to support the container 1 on the ground, thereby increasing the force-bearing position at the bottom of the container 1 and supporting the container 1. Moreover, even after the invention is separated from the trailer, the invention can remain stably in place due to the arrangement of the wheel 3 and the support legs 4.

[0040] In order to process organic waste, such as Figure 1 and 2 As shown, a waste treatment mechanism 6 for processing organic waste is provided inside the container 1;

[0041] Specifically, the waste treatment mechanism 6 includes a rotary high-temperature dryer 61 located at the top front of the interior of the container 1. The rotary high-temperature dryer 61 is located at the top front of the interior of the container 1. A first screw conveyor 62 is provided at the inlet on one side of the rotary high-temperature dryer 61. Organic waste enters the rotary high-temperature dryer 61 through the first screw conveyor 62. Moreover, an exhaust pipe 64 is connected to the top side of the rotary high-temperature dryer 61 through a flange and bolts. The top of the exhaust pipe 64 penetrates the container 1 and extends out of the top of the container 1 to discharge the hot air generated when the container 1 is drying organic waste.

[0042] Furthermore, in the above technical solution, the bottom of the rotary high-temperature dryer 61 is fixed to the inner wall of the container 1 by an I-beam bracket, and the bottom of the first screw conveyor 62 is fixed with two support rods 63, the bottom ends of the support rods 63 are fixed to the bottom of the container 1 by bolts;

[0043] Before putting organic waste into the rotary high-temperature dryer 61, it needs to be preliminarily sorted into animal waste and plant waste. The drying temperatures required for these two types of organic waste are different. Animal waste includes food scraps such as chicken bones, duck bones, goose bones, pig bones, cow bones, and sheep bones. This type of waste requires a drying temperature of over 200 degrees Celsius. Plant waste includes scraps of various vegetables and fruits. This type of waste can be dried at a temperature between 100 and 150 degrees Celsius.

[0044] During the drying process using the rotary high-temperature dryer 61, the wastewater in the organic waste will evaporate at high temperature, and the hot air will be discharged into the external environment through the exhaust pipe 64 to avoid the generation of wastewater. Therefore, there is no need for additional treatment or collection of the wastewater. Moreover, the high temperature inside the rotary high-temperature dryer 61 can effectively kill pathogenic microorganisms in the organic waste and prevent the discharged hot air from polluting the surrounding environment.

[0045] like Figure 3-6 As shown, a crusher 65 is provided at the outlet on the other side of the rotary high-temperature dryer 61. The bottom of the crusher 65 is connected to a second screw conveyor 66. A belt conveyor 68 is provided on the side of the second screw conveyor 66 away from the crusher 65. The belt conveyor 68 is located inside the rear of the container 1. A briquetting box 69 is provided at the end of the belt conveyor 68 away from the second screw conveyor 66. The organic waste dried by the rotary high-temperature dryer 61 enters the crusher 65 and is crushed by the crusher 65. Then, the crushed organic waste is conveyed by the second screw conveyor 66 and the belt conveyor 68 into the briquetting box 69 and is compressed into blocks.

[0046] Furthermore, in the above technical solution, a limiting cover 67 is fixed on the top of the side of the second screw conveyor 66 away from the crusher 65 and close to the belt conveyor 68. The limiting cover 67 is located directly above the belt conveyor 68. The organic waste conveyed by the second screw conveyor 66 falls onto the top of the belt conveyor 68 under the restriction of the limiting cover 67.

[0047] To facilitate the conveyor belt 68 in transferring the crushed organic waste into the briquetting box 69, such as... Figure 7-9 As shown, a feed inlet 610 is provided on the side of the briquetting box 69 near the belt conveyor 68. An inclined platform 611 is provided at the bottom of the feed inlet 610. The inclined platform 611 is located on one side of the belt conveyor 68. One end of the belt conveyor 68 extends into the feed inlet 610. A discharge outlet 612 is provided on the side of the briquetting box 69 away from the belt conveyor 68.

[0048] The top of the briquetting box 69 is fixed with a third electric cylinder 618. The piston rod end of the third electric cylinder 618 is fixed with a pressing plate 617. The pressing plate 617 is in contact with the inner wall of the briquetting box 69. The bottom of the pressing plate 617 is provided with a rotating plate 615.

[0049] The organic waste transported to the briquetting box 69 by the belt conveyor 68 still contains a certain amount of moisture. At this time, the third electric cylinder 618 is activated. The piston rod inside the third electric cylinder 618 extends downward and drives the extrusion plate 617 to move downward, extruding the organic waste that falls on the top of the rotating plate 615 until the piston rod inside the third electric cylinder 618 extends to its longest distance. At this time, the waste that falls on the top of the rotating plate 615 is extruded into a block with the same shape as the inner cavity of the briquetting box 69. This extrusion method helps to reduce the volume occupied by the organic waste. Moreover, by extruding it into a rectangular shape with a regular surface, it is also easier for workers to handle it.

[0050] To facilitate the removal of compressed, blocky organic waste from the briquetting container 69, such as Figure 9 As shown, the rotating plate 615 is rotatably connected to the side wall of the container 1 on the side away from the feed inlet 610. A second electric cylinder 616 is hinged at the middle of the bottom of the rotating plate 615. The bottom end of the second electric cylinder 616 is hinged to the bottom of the container 1. The piston rod end of the second electric cylinder 616 extends and pushes the rotating plate 615 to rotate inside the briquetting box 69 so as to push the blocky organic waste located on the top of the rotating plate 615 out of the discharge port 612.

[0051] In addition, such as Figure 7-9 As shown, bamboo-joint telescopic rods 619 are fixed at the four corners of the top of the pressing box 69. The bottom of the bamboo-joint telescopic rods 619 is fixed to the four corners of the top of the extrusion plate 617. While pushing the extrusion plate 617 downward, the third electric cylinder 618 also drives the bottom of the four bamboo-joint telescopic rods 619 to extend downward, so as to ensure that the four corners of the extrusion plate 617 can be subjected to uniform force and prevent the extrusion plate 617 from tilting and affecting the normal extrusion effect.

[0052] Furthermore, when compressing organic waste inside the briquetting box 69, such as Figure 7As shown, a briquetting box door 613 is inserted inside the discharge port 612. Two first electric cylinders 614, arranged vertically, are fixed on one side of the briquetting box door 613. The first electric cylinders 614 are fixed to the outer wall of the briquetting box 69 by a bracket. The briquetting box door 613 can block the organic waste inside the briquetting box 69 and prevent it from leaking out of the discharge port 612. After the organic waste is compressed into blocks, by activating the two first electric cylinders 614, the extension of the piston rods inside the two first electric cylinders 614 can drive the briquetting box door 613 to move away from the discharge port 612 until the discharge port 612 is exposed. This allows the inclined rotating plate 615 to push the blocks of organic waste out of the discharge port 612.

[0053] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
