Description

Technical Field

[0001] This utility model relates to the field of municipal solid waste technology, and in particular to a sorting and recycling device for low-value recyclable materials from municipal solid waste. Background Technology

[0002] Household waste refers to solid waste generated in daily life or in activities that provide services for daily life. Household waste can generally be divided into kitchen waste, recyclable waste, hazardous waste, and other waste. Examples include leftover food, paper, plastic, glass, batteries, and fluorescent tubes discarded in daily life. Currently, low-value recyclable materials are quite common in household waste, making sorting and reuse inevitable. Sorting and reuse can efficiently improve resource utilization and protect the environment.

[0003] Chinese patent document CN216064814U discloses a sorting and recycling device for low-value recyclables, including a box, a telescopic rod, a stirring rod, a brush rod, a liquid collection box, and a solid collection box. A hydraulic cylinder is fixedly installed on the right side of the inlet, and a telescopic rod is fixedly connected to the lower end of the hydraulic cylinder. The telescopic rod drives a motor and a rotating rod to move downwards. The output end of the motor is fixedly connected to the rotating rod. A stirring rod is fixedly installed through the left end of the rotating rod, and a brush rod is fixedly installed through the right end of the rotating rod. Thus, the stirring rod and the brush rod can separate the recyclables. The water inlet can provide water flow to soak and dissolve the separated recyclables. Magnets are fixedly installed at both ends of the lower side of the processing box to attract metal objects. After filtration through the filter port, the solids and liquids are separated. A fan and a heating plate dry the solids. Finally, the fan draws the solids into the solid collection box, and the liquid is introduced into the liquid collection box through the drain pipe.

Detailed Implementation

[0031] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0032] Example 1: Please refer to Figure 1 , Figure 2 , Figure 4 - Figure 6 This utility model provides a technical solution: a sorting and reuse device for low-value recyclable materials of household waste, including an installation frame 1;

[0033] The transmission belt 2 is fixedly installed on the inner side of the mounting frame 1;

[0034] A crushing frame 3 extends from the top surface of the fixed mounting frame 1 into the interior of the mounting frame 1. A crushing device 8 is fixedly installed on the inner side of the crushing frame 3. The crushing device 8 consists of two motors and two relatively rotating crushing rollers. The crushing rollers are driven by the motor output rods, and then the two crushing rollers crush the garbage. The roller surface of the crushing rollers is provided with staggered arc-shaped convex teeth (the distance between the convex teeth is 5mm). The crushing roller speed is 50-80r / min. For wrapped plastic film and textiles, the arc-shaped convex teeth can tear them into 5-10cm fragments. For large pieces of household waste (such as fruit peels and paper balls), preliminary crushing is achieved.

[0035] The feed pipe 5 extends from the top surface of the crushing frame 3 into the interior of the crushing frame 3;

[0036] A fixed connecting frame 7 extends through the front of the mounting frame 1 and into the interior of the mounting frame 1;

[0037] And a connecting frame 4 fixedly connected to the top surface of the mounting frame 1, a wind-powered sorting component 60 is provided inside the connecting frame 7, and a magnetic separation component 61 is provided inside the connecting frame 4;

[0038] The wind-powered sorting component 60 includes a first impurity removal screen 603 fixedly installed on the inner side of the connecting frame 7, a collection frame 604 is provided below the connecting frame 7, two baffles 605 are provided inside the collection frame 604, an installation plate 601 is fixedly connected to the front of the connecting frame 7, and an air pump 602 is fixedly installed on the top surface of the installation plate 601.

[0039] The exhaust pipe of the air pump 602 is fixedly extended through the front of the connecting frame 7 and into the interior of the connecting frame 7. The exhaust pipe of the air pump 602 is located in front of the first impurity removal screen 603. The top surface of the collection frame 604 is fixedly extended through the bottom surface of the connecting frame 7 and into the interior of the connecting frame 7. The collection frame 604 is located behind and below the first impurity removal screen 603.

[0040] The two baffles 605 are fixedly connected to the front and rear sides of the inside of the collection frame 604 respectively. The two baffles 605 are staggered vertically to prevent the backflow of light materials and ensure stable material collection.

[0041] The collection frame 604 has a frame door 606 hinged to the front. An inclined plate 608 is fixedly connected to the inner side of the mounting frame 1. The inclined plate 608 is located at the lower left of the crushing frame 3. The inclined plate 608 facilitates the crushed waste to fall onto the transmission belt 2.

[0042] An air inlet is provided on the rear side of the mounting frame 1. A filter 607 is fixedly connected to the inner side of the air inlet to prevent external impurities or dust from entering the air inlet.

[0043] A fixing frame 609 is fixedly connected to the inner side of the crushing frame 3. The fixing frame 609 is located above the crushing device 8. A second impurity removal screen 6010 is fixedly connected to the inner side of the fixing frame 609. A drain pipe 6011 is provided below the second impurity removal screen 6010. The front end of the drain pipe 6011 is fixedly connected through the inner front side of the crushing frame 3 and extends to the front side of the crushing frame 3. A discharge port is provided through the side of the crushing frame 3 and is located above the second impurity removal screen 6010.

[0044] Both the first impurity removal screen 603 and the second impurity removal screen 6010 are configured as vibrating first impurity removal screens. The vibration design prevents the first impurity removal screen 603 and the second impurity removal screen 6010 from becoming clogged.

[0045] The first impurity removal screen 603 in the connecting frame 7, which is designed to vibrate, is connected to the air pump 602 on the mounting plate 601 to form a negative pressure environment. This allows for the rapid separation of lightweight materials such as plastic film and textiles from the conveyor belt 2. Meanwhile, the second impurity removal screen 6010 in the fixed frame 609 inside the crushing frame 3 is designed to vibrate. This effectively filters the liquid components in the municipal solid waste, preventing the liquid from mixing with the solid materials and increasing the difficulty of subsequent sorting. The filtered liquid is discharged directionally through the drain pipe 6011, which reduces the weight of the material and prevents the liquid from corroding the subsequent sorting components. No additional drying steps are required, which greatly improves the sorting efficiency.

[0046] Example 2: Based on Example 1, a preferred embodiment of the sorting and recycling device for low-value recyclable materials of household waste provided by this utility model is as follows: Figure 1 - Figure 3 , Figure 5 and Figure 7 As shown: The magnetic separation assembly 61 includes a support frame 612 located inside the connecting frame 4. An electric push rod 611 is fixedly connected to the top surface of the connecting frame 4. The bottom end of the output rod of the electric push rod 611 extends through the top surface of the connecting frame 4 to the inside of the connecting frame 4. The bottom end of the output rod of the electric push rod 611 is fixedly connected to the top surface of the support frame 612. A rotating roller 614 is provided inside the support frame 612. The rear end face of the rotating roller 614 is rotatably connected to the rear side inside the support frame 612 through a bearing seat. A through groove is provided on the top surface of the mounting frame 1. The through groove is located below the connecting frame 4. A magnetic ring plate 615 is fixedly sleeved on the surface of the rotating roller 614. The wires of the magnetic ring plate 615 are connected to the power supply wires through an electric slip ring to prevent the wires from getting tangled when the magnetic ring plate 615 rotates.

[0047] A motor 613 is fixedly connected to the front of the support frame 612. The rear end face of the output rod of the motor 613 extends through the front of the support frame 612 to the inside of the support frame 612. The rear end face of the output rod of the motor 613 is fixedly connected to the front end face of the rotating roller 614. The motor 613 drives the rotating roller 614 to rotate, so that metal can be adsorbed on the surface of the magnetic ring plate 615.

[0048] Through the magnetic separator 61, the electric push rod 611 on the connecting frame 4 can flexibly adjust the height of the support frame 612, so that the magnetic ring plate 615 on the surface of the roller 614 can accurately fit the material layer above the transmission belt 2, adapting to the sorting requirements of materials of different thicknesses. At the same time, the motor 613 drives the roller 614 to rotate, allowing the magnetic ring plate 615 to adsorb metal impurities in the material from all directions, avoiding adsorption dead zones. After the magnetic ring plate 615 is powered off, the metal impurities can quickly fall off, making it easy to collect them in a concentrated manner, realizing the precise separation of metals from other materials and improving the comprehensiveness of resource recycling.

[0049] It should be noted that the specific installation methods, circuit connection methods, and control methods of the transmission belt, crushing device, motor, electric push rod, electromagnet, and air pump used in this utility model are all conventional designs, and will not be described in detail here.

[0050] The working principle of this utility model is as follows:

[0051] Household waste is poured into the fixed frame 609 inside the crushing frame 3 through the feed pipe 5. The second impurity removal screen 6010 inside the fixed frame 609 is vibrated to filter the liquid contained in the waste. The filtered liquid is discharged through the drain pipe 6011, completing the initial separation of solid and liquid.

[0052] After liquid separation, the solid waste falls into the crushing device 8 below through the discharge port on the side of the crushing frame 3. After the crushing device 8 is started, it crushes the solid waste, breaking down large pieces of waste into smaller pieces that are easier to sort later.

[0053] The crushed solid material slides down the inclined plate 608 inside the mounting frame 1 onto the transmission belt 2, which then drives the material forward. Simultaneously, the air pump 602 on the mounting plate 601 on the front of the connecting frame 7 is activated. The air pump 602 draws air from inside the connecting frame 7 through the air extraction pipe, creating a negative pressure inside the connecting frame 7. Under the action of the negative pressure, the filter screen 607 built into the air inlet at the rear of the mounting frame 1 prevents external impurities from entering the introduced air. The air carries lightweight materials such as plastic film and textiles from the transmission belt 2 into the connecting frame 7. The lightweight materials are filtered by the vibration design of the first impurity removal screen 603 inside the connecting frame 7. The gas is extracted by the air pump 602, and the lightweight materials, under the vibration of the first impurity removal screen 603, fall into the bottom of the inner side of the collection frame 604 after passing through two staggered baffles 605 to complete the collection.

[0054] The electric push rod 611 on the top surface of the connecting frame 4 is activated. The output rod of the electric push rod 611 extends, driving the support frame 612 connected to its bottom to move downward. This causes the rotating roller 614 on the inner side of the support frame 612 to pass through the through groove on the top surface of the mounting frame 1 and move to a suitable adsorption position above the transmission belt 2. The motor 613 on the front of the support frame 612 is turned on. The output shaft of the motor 613 drives the rotating roller 614 to rotate, and at the same time, it energizes the magnetic ring plate 615 on the surface of the rotating roller 614. The rotating magnetic ring plate 615 generates a magnetic field, which adsorbs metal impurities in the material on the transmission belt 2, realizing the separation of metal from other materials. A garbage box is placed on the right side of the transmission belt 2. The remaining garbage falls into the garbage box after being transported on the transmission belt 2.

[0055] After sorting, open the frame door 606 hinged to the front of the collection frame 604 and take out the lightweight material collected inside; turn off the power to the magnetic ring plate 615, and the metal impurities adsorbed on its surface lose their magnetism and fall onto the transmission belt 2. By placing a collection box on the right side of the transmission belt 2, the collection of metal materials is completed, and the classification and recycling of low-value recyclables is finally realized.

[0056] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
