Description

Technical Field

[0001] The present application relates to the technical field of waste treatment, and in particular to an intelligent classification device for urban domestic organic waste. Background Art

[0002] Organic waste refers to waste containing organic components in domestic waste, mainly paper, fiber, bamboo, wood, kitchen waste, etc., which is also called wet waste. Kitchen waste is perishable and accompanied by odor, and is not suitable for incineration or direct landfill. Anaerobic fermentation is one of the main methods for treating organic waste. The organic waste is prepared into a slurry and then passed into a storage tank for anaerobic fermentation to generate bioenergy, which can be well utilized.

[0003] However, the existing urban domestic organic waste classification and sorting devices still have some shortcomings. For example, in addition to organic waste, kitchen waste is often mixed with metal debris such as metal knives and forks, metal bottle caps, and large non-metal debris such as glass bottles and lunch boxes. The existing devices cannot intelligently classify and sort them, and manual sorting is required in the sorting room, which is time-consuming, labor-intensive, and cumbersome. The existing intelligent classification trash cans lack further sorting for organic waste with a high water content, which will greatly affect the biological treatment effect of organic waste. Utility Model Content

[0004] The intelligent classification device for urban domestic organic waste proposed in this application is intended to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, this application adopts the following technical solutions:

[0006] The intelligent classification device for urban domestic organic waste comprises a classification cabin, a partition is fixedly connected between the inner walls on both sides of the classification cabin, a garbage detection platform is fixed at the top center of the partition, symmetrically distributed discharge ports are arranged at both ends of the garbage detection platform, a wet bucket and a dry bucket are respectively arranged below the two discharge ports, a solid-liquid separation mechanism is arranged on the inner side of the wet bucket, a screw drive mechanism is fixed to the inner top of the classification cabin, a grasping detection mechanism is fixed to the moving end of the screw drive mechanism, a garbage delivery port is opened at the front upper end of the classification cabin, and a PLC controller is fixed to one side of the top of the classification cabin.

[0007] By adopting the above technical scheme, the packaged organic garbage is put into the garbage delivery port and placed on the garbage detection table, and then the grabbing detection mechanism is started, and the humidity of the garbage is detected by inserting the probe of the garbage moisture meter into the garbage. When the humidity in the garbage is detected, the screw drive mechanism drives the grabbing detection mechanism to grab it to the discharge port above the wet barrel through the clamp and drop it into the wet barrel. If the humidity in the garbage is not detected, it is grabbed by the clamp to the discharge port above the dry barrel and dropped, so that the garbage is separated into dry and wet parts, thereby improving the biological treatment effect of organic garbage.

[0008] As a preferred embodiment, the solid-liquid separation mechanism includes a hydraulic rod, a U-shaped bracket, a pressure plate and a porous leak plate, one end of the pressure plate is hinged to the inner wall of the wet barrel, the porous leak plate is fixed to the inner lower end of the wet barrel, the hydraulic rod is hinged to the upper end of the inner wall of one side of the wet barrel, the piston rod end of the hydraulic rod is fixedly connected to the U-shaped bracket, the inner walls on both sides of the U-shaped bracket are rotatably connected with pins, strip grooves matching the pins are opened on both sides of the pressure plate, and cleaning columns arranged in an array are evenly fixed on the bottom of the pressure plate, and the cleaning columns are matched with the leakage holes of the porous leak plate.

[0009] By adopting the above technical solution, the U-shaped bracket is driven to move by the hydraulic rod, and the U-shaped bracket then drives the pressure plate to move. During this process, the pin shaft slides in the strip groove, and the pressure plate moves in a circle around the hinge with the inner wall of the wet barrel, and compresses the organic waste during the downward pressing process, thereby squeezing out the moisture in the organic waste and flowing it into the inner bottom of the wet barrel from the leakage holes of the porous leakage plate.

[0010] As a preferred embodiment, the grabbing and detecting mechanism includes a cylinder, a protective cover and a garbage moisture meter. The protective cover is fixed to the lower end of the first cylinder, the second cylinder is fixed to the inner top of the protective cover, the piston rod of the second cylinder is fixedly connected to a mounting seat, the inner side of the mounting seat is rotatably connected to a fixed shaft, the front end of the fixed shaft is sleeved with two symmetrically arranged jaws, the middle part of the jaws is rotatably connected to the two sides of the protective cover through a connecting shaft, and the garbage moisture meter is fixed to the bottom of the mounting seat.

[0011] By adopting the above technical solution, when the gripper grabs garbage, the first cylinder drives the protective cover and the gripper to move downward to above the garbage, the piston rod of the second cylinder moves downward and drives the two grippers to open, and at the same time, drives the probe of the garbage moisture meter to be inserted into the packaged garbage. After the detection is completed, the piston rod of the cylinder is reset and drives the two grippers to move closer to each other, thereby grabbing the garbage, and then the screw drive mechanism moves it to above the discharge port and opens the gripper to throw it into the wet bucket or dry bucket.

[0012] As a preferred embodiment, a pressure sensor is fixed at the center of the surface of the garbage detection platform, and the output ends of the pressure sensor are electrically connected to the input ends of the PLC controller.

[0014] As a preferred embodiment, the output ends of the garbage moisture meter are electrically connected to the input ends of the PLC controller, and the output ends of the PLC controller are electrically connected to the input ends of the cylinder and the hydraulic rod respectively.

[0015] By adopting the above technical solution, the garbage moisture meter and the pressure sensor will transmit electrical signals to the PLC controller respectively, and the PLC controller will then control the cylinder and the hydraulic rod to perform garbage moisture detection and solid-liquid separation operations.

[0016] As a preferred embodiment, a drain pipe is fixedly connected to one side of the bottom of the wet barrel, and a valve is fixed on the drain pipe.

[0017] By adopting the above technical solution, the valve is opened and the drain pipe is used to discharge the squeezed liquid to avoid accumulation and odor.

[0018] Beneficial effects of this application:

[0019] The intelligent classification device for urban domestic organic waste is equipped with a garbage detection table, a grabbing detection mechanism and a solid-liquid separation mechanism. The packaged organic waste is put into the garbage delivery port and placed on the garbage detection table. The humidity of the waste is then detected by the grabbing detection mechanism. The waste is then grabbed by the clamp and dropped into the discharge port above the wet bucket or dry bucket, thereby separating the wet and dry waste. The solid-liquid separation mechanism is used to further separate the solid and liquid of the organic waste, thereby improving the biological treatment effect of the organic waste.

Then the grabbing detection mechanism 9 is started, and the garbage moisture meter 93 is inserted into the garbage to detect the humidity of the garbage. When the humidity in the garbage is detected, the screw driving mechanism 8 drives the grabbing detection mechanism 9 to grab it to the discharge port 4 above the wet bucket 5 through the clamping claw 96 and drop it into the wet bucket 5. If the humidity in the garbage is not detected, it is grabbed by the clamping claw 96 to the discharge port 4 above the dry bucket 6 and dropped, so as to separate the dry and wet garbage, thereby improving the biological treatment effect of the organic garbage.

One end of the pressing plate 73 is hinged to the inner wall of the wet barrel 5. The porous leaking plate 74 is fixed to the inner lower end of the wet barrel 5. The hydraulic rod 71 is hinged to the upper end of the inner wall of one side of the wet barrel 5. The piston rod end of the hydraulic rod 71 is fixedly connected to the U-shaped bracket 72. The inner walls on both sides of the U-shaped bracket 72 are rotatably connected with a pin shaft 75. Both sides of the pressing plate 73 are provided with a strip groove 731 adapted to the pin shaft 75. The bottom of the pressing plate 73 is evenly fixed with cleaning columns 73 arranged in an array. 2. The cleaning column 732 is matched with the leakage hole of the porous leakage plate 74. The U-shaped bracket 72 is driven to move by the hydraulic rod 71, and the U-shaped bracket 72 then drives the pressing plate 73 to move. During this process, the pin shaft 75 slides in the strip groove 731, and the pressing plate 73 moves in a circle around the hinge with the inner wall of the wet barrel 5, and compresses the organic waste during the downward pressing process, thereby squeezing out the water in the organic waste and flowing it from the leakage hole of the porous leakage plate 74 into the inner bottom of the wet barrel 5.

At the bottom of the mounting seat 94, when the clamp grabs the garbage, the first cylinder 97 drives the protective cover 92 and the clamp 96 to move downward to above the garbage, and the piston rod of the second cylinder 91 moves downward and drives the two clamps 96 to open. At the same time, it drives the probe of the garbage moisture meter 93 to be inserted into the packaged garbage.

[0030] Reference Figure 2 and Figure 3 A pressure sensor 31 is fixed in the center of the surface of the garbage detection platform 3. The output end of the pressure sensor 31 is electrically connected to the input end of the PLC controller 11. When the packaged garbage is placed on the surface of the garbage detection platform 3, the pressure sensor 31 receives the pressure signal and converts it into an electrical signal and transmits it to the PLC controller 11, thereby facilitating the next step.

[0031] Reference Figure 1 and Figure 3 The output ends of the garbage moisture meter 93 are electrically connected to the input ends of the PLC controller 11, and the output ends of the PLC controller 11 are electrically connected to the input ends of the second cylinder 91 and the hydraulic rod 71 respectively. The garbage moisture meter 93 and the pressure sensor 31 will respectively transmit electrical signals to the PLC controller 11, and the PLC controller 11 then controls the second cylinder 91 and the hydraulic rod 71 to perform garbage moisture detection and solid-liquid separation operations.

[0033] Working principle: First, the packaged organic garbage is put into the garbage inlet 10 and placed on the garbage detection table 3. At this time, the pressure sensor 31 receives the pressure signal and converts it into an electrical signal and transmits it to the PLC controller 11. The PLC controller 11 then starts the grabbing detection mechanism 9 to detect the humidity of the garbage. When the humidity in the garbage is detected, when the jaws grab the garbage, the first cylinder 97 drives the protective cover 92 and the jaws 96 to move downward to above the garbage, and the piston rod of the second cylinder 91 moves downward and drives the two jaws 96 to open. At the same time, it drives the probe of the garbage moisture meter 93 to be inserted into the packaged garbage. After the detection is completed, the piston rod of the second cylinder 91 is reset and drives the two jaws 96 to move closer to each other, thereby grabbing the garbage, and then it is moved to above the discharge port 4 through the screw drive mechanism 8 and the jaws 96 are opened. It is thrown into the wet barrel 5. If the humidity in the garbage is not detected, it is grabbed by the clamp 96 and thrown into the discharge port 4 above the dry barrel 6, so as to perform preliminary dry-wet separation of the garbage; then, the U-shaped bracket 72 is driven to move by the hydraulic rod 71, and the U-shaped bracket 72 then drives the pressure plate 73 to move. During this process, the pin shaft 75 slides in the strip groove 731, and the pressure plate 73 moves in a circle around the hinge with the inner wall of the wet barrel 5, and compresses the organic garbage during the downward pressing process, thereby squeezing out the moisture in the organic garbage and flowing it into the inner bottom of the wet barrel 5 from the leakage holes of the porous leakage plate 74. The drain pipe 51 is used to discharge the squeezed liquid to avoid accumulation and odor. The cleaning column 732 cooperates with the leakage holes of the porous leakage plate 74 to prevent organic matter from clogging the leakage holes, and further performs solid-liquid separation on the organic garbage, thereby improving the biological treatment effect of the organic garbage.
