Description

Technical Field

[0001] The present invention relates to the technical field of garbage classification and processing, and in particular to an intelligent garbage classification and recycling device. Background Art

[0002] In recent years, with the growth of population, the amount of domestic waste has also increased. Domestic waste and the odor it produces are everywhere in our living space. At present, the treatment of waste is mainly centralized collection, unified landfill or incineration. When centralized collection is carried out in living areas, it is mainly to place trash cans in people's living areas for classified collection. Since most trash cans are open, people tend to throw garbage into the trash cans at will when throwing garbage, which makes it difficult to classify and cannot be well recycled after garbage collection; and when the open trash cans are filled with garbage, even if the trash cans are covered with lids, the garbage is easy to rot and produce odor, affecting people's daily life and polluting the environment; and the volume of the trash can is limited. When loading garbage, it is easy for the garbage to support the space inside, so that the trash can cannot be filled, but the garbage has been piled up to the entrance of the trash can, affecting the utilization rate of the trash can and reducing the work efficiency of the garbage collector; when recycling garbage, due to the limited capacity of the trash can and the inability to inform the garbage recycling staff in time, it is easy to cause the garbage to pile up outside or overflow, affecting the environment, and it is easy to produce odor to pollute the environment.

[0043] In order to more clearly describe the content of the present invention, the following description is made in conjunction with specific embodiments:

[0044] Example 1

[0045] The specific application of the present invention when used as an intelligent garbage classification and recycling device is as follows: the solar panel (monocrystalline 200W solar panel) converts electricity and stores it in the battery, which is then used to power the extrusion device, the air purification device, the display screen, the main board (PLC all-in-one machine Shuangyuan Technology PLC08), the solenoid valve (KOB KT-L60) and other electrical components, and each electrical component is also powered by the current in the power grid; when in use, the user selects the classification of the garbage through the operation button on the display screen, and the signal is transmitted to the main board, and the main board controls the electromagnetic valve at the entrance of the garbage bin of the corresponding classification to cut off the power, so that the small door at the entrance is opened, and the user throws the garbage from the opened small door. When the main board controls the electromagnetic valve, the air purification device is turned on at the same time, and the fan rotates to suck the gas in the garbage classification and recycling device into the air purification device, so that the gas is not easy to be emitted from the small door to pollute the air. After the fan sucks the gas, the gas is filtered and adsorbed by the activated carbon, and then filtered and adsorbed by the filter element into the space of the purification area. After the ultraviolet lamp sterilizes and disinfects the gas, the gas is discharged from the air outlet into the atmosphere through the ventilation duct between the wind shield and the partition. By purifying and discharging the gas generated by the garbage, the pollution of the environment by the gas generated by the garbage is reduced. The wind shield can prevent the ultraviolet lamp from The light leakage causes damage; after the user throws the garbage into the opened garbage opening, the main board controls the solenoid valve to energize and close the small door, and the garbage falls into the garbage bin along the channel bin. The main board controls the squeezing device above the garbage bin to move downward, pushing the squeezing plate to press down and compress the garbage. The on-off of the squeezing device circuit is controlled by the pressure sensor arranged in the squeezing plate. When the back pressure of the garbage is greater than the preset value of the pressure sensor, the main board controls the squeezing device to move up to the top of the connection port between the channel bin and the transition bin to complete the compression of the garbage. In the process of compressing the garbage, the distance sensor arranged on the partition of the recycling area determines the distance when the squeezing plate moves up after the pressure sensor moves down, thereby determining the capacity of the garbage bin. When the squeezing plate moves down a quarter of the distance from the opening end of the garbage bin, the main board connects the signal transmitter to send a signal to the receiving end to inform the capacity of the garbage bin and arrange the garbage recycling personnel to prepare to recycle the garbage.

[0046] When there is no user throwing away garbage, the main board controls the air purification device to operate every 30 minutes, purifying the gas generated by the garbage in the recycling device before discharging it to reduce pollution to the environment; an ultraviolet lamp is installed in the working area, which is in the normally on state for disinfection and sterilization.

[0047] When the garbage collector transfers the garbage in the garbage bin to the garbage truck, he opens the rear door from the back of the garbage recycling device and pulls the garbage bin out along the slide rail. After pushing the top cover out along the slide slot, he pushes the top cover to rotate along the slide column to close the bottom cover on the open end of the garbage bin, lifts the garbage bin to the garbage truck so that the bottom of the garbage bin faces the car body, takes out the latch, opens the bottom cover and dumps the garbage. Since the garbage has been compressed, the inner layer of the garbage bin moves downward under the action of the neutral force and the inner layer of the garbage bin moves downward under the action of gravity when dumping the garbage. The slide column connecting the inner layer of the garbage bin moves along the wedge-shaped slide slot to separate the inner layer of the garbage bin, reducing the squeezing force on the garbage and causing the garbage to fall into the garbage transfer truck.

[0048] After the trash bin is emptied, the bottom cover is closed on the bottom of the trash bin. The arc-shaped side wall of the bottom cover moves the inner layer of the trash bin upwards, and the sliding column connecting the trash bin moves upward along the wedge-shaped slide to collect the inner layer of the trash bin. The side panels are engaged in the slots of the bottom cover. The sides of the trash bin are connected with 45° bevel edges to facilitate the folding and separation of the side panels. After the bottom panel is closed, it is fixed with a latch. Open the top cover of the trash bin, put the top cover back into the slide, put the trash bin into the pavilion along the slide rail, and close the rear door of the garbage recycling device.

[0049] Example 2

[0050] Based on the implementation method of Example 1, the specific application of the present invention for determining the capacity of a garbage bin when used as an intelligent garbage sorting and recycling device is as follows: when measuring the capacity of the garbage bin, a contact switch is provided at the end of the transition bin facing the partition, and a contact head cooperating with the contact switch is provided at the end of the moving sleeve of the extrusion device close to the partition. As the moving sleeve moves downward, the capacity of the garbage bin is measured according to the downward distance and the action of the pressure sensor. When the contact head is closed in contact with the contact switch, the remaining capacity of the garbage bin is one quarter, and the signal is transmitted to the main board. The main board turns on the signal transmitter to send the signal to the receiving end, informing the capacity of the garbage bin and arranging the garbage recycling personnel to prepare to recycle the garbage.

[0051] Example 3

[0052] Based on Example 1 and Example 2, the intelligent garbage classification and recycling device is used for recycling domestic garbage in a residential area.
