Description

Technical Field

[0001] This utility model relates to the field of household waste treatment technology, and in particular to a smart household dry waste processor. Background Technology

[0002] In modern household life, a large amount of dry waste is generated, such as disposable napkins after meals, toilet paper after using the toilet, and sanitary napkins. This waste is typically characterized by high frequency of generation, small amounts per instance, and slow biodegradability. Currently, most households use traditional centralized garbage collection in bins, which are then transported by the sanitation system to public waste treatment stations for centralized processing.

[0003] However, this traditional waste disposal method has many shortcomings:

[0004] First, the transportation of waste from households to treatment plants not only consumes a significant amount of manpower and time but also increases the burden on urban traffic and management. Second, during storage and transportation within households, dry waste is easily mixed with other types of waste, causing odor diffusion and bacterial growth, thus leading to secondary environmental pollution. Third, the mixing of various types of waste complicates subsequent treatment processes, especially when dry waste is mixed with wet or liquid waste, significantly increasing the difficulty and cost of incineration or resource recovery. Finally, traditional treatment methods fail to effectively utilize the potential resource value of dry waste, resulting in resource waste and failing to meet the current requirements for green and sustainable development.

[0005] Therefore, there is an urgent need to provide a household waste disposal device that can achieve on-site treatment of dry waste, reduce transportation links, reduce environmental pollution risks, and has resource recycling potential, in order to overcome the above-mentioned defects in the existing technology. Utility Model Content

[0006] To address the aforementioned issues, this utility model proposes a household dry waste intelligent processor with a reasonable structure, intelligent operation, and energy-saving and environmentally friendly features. It aims to achieve immediate carbonization, harmless discharge, and resource reuse of dry waste, thereby effectively improving the efficiency and environmental protection level of household waste disposal.

[0007] The technical solution adopted in this utility model is as follows:

[0008] A household dry waste intelligent processor includes a carbonization box, in which a set of horizontally spaced carbonization rods are installed in the middle of the carbonization box. The carbonization rods divide the interior of the carbonization box into an upper waste carbonization chamber and a lower ash mixing chamber. An ash mixing component is installed in the lower ash mixing chamber.

[0009] The carbonization box is equipped with a waste inlet for feeding waste into the upper carbonization chamber, and a flue pipe connecting the top of the carbonization box to the upper carbonization chamber. The bottom rear side of the carbonization box is equipped with a water inlet that connects to the lower ash mixing chamber, and a water inlet pipe is installed outside the carbonization box through the water inlet. The bottom of the carbonization box is equipped with a sewage outlet, and a sewage outlet pipe is installed outside the carbonization box through the sewage outlet.

[0010] Furthermore, the carbonization box is a rectangular metal box; a waste inlet is provided on the front of the carbonization box, and closed doors are installed on both sides of the waste inlet via sliding rails.

[0011] Furthermore, the ash mixing assembly includes a mixing motor installed outside the carbonization box, a mixing shaft rotatably installed in the lower ash mixing chamber, and a metal mesh cylinder installed on the mixing shaft; the output shaft of the mixing motor is connected to the mixing shaft.

[0012] Furthermore, a control box is installed on the top of the carbonization box, and electromagnetic valves are installed at both the water inlet and the sewage outlet. A duct fan is installed on the exhaust pipe. The electrical control box is electrically connected to the stirring motors of each electrical control valve, carbonization rod, duct fan, and ash mixing assembly.

[0013] Furthermore, a high-temperature heat insulation plate is installed on the inner wall of the upper waste carbonization chamber.

[0014] Compared with existing technologies, the household dry waste intelligent processor provided by this utility model has the following significant advantages and positive effects:

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. Example 1

[0026] This embodiment provides a smart household dry waste processor for handling household dry waste. For example... Figure 1 , Figure 2 and Figure 3 As shown, the household dry waste intelligent processor includes a carbonized housing 1, which is a rectangular metal structure, preferably made of 304 stainless steel, which has good high temperature resistance and structural strength.

[0027] like Figure 4As shown, a set of carbonization rods 2 is installed in the middle of the carbonization box. These carbonization rods 2 are horizontally spaced within the box and serve as heating elements to burn and carbonize the waste. In this embodiment, the carbonization rods 2 are commercially available ceramic-encapsulated electric heating tube type carbonization rods, such as the Zhejiang Hualong HL-8826 type carbonization rod, with a rated power of 1kW and an operating temperature range of 250~400℃, suitable for small carbonization furnaces. Figure 4 As shown, the interior of the carbonization box is divided into an upper waste carbonization chamber 3 and a lower ash mixing chamber 4 by a set of horizontally spaced carbonization rods 2.

[0028] The carbonization chamber 1 is equipped with a waste inlet 5 that connects to the upper carbonization chamber 3 for waste disposal. Sealing doors 12 are installed on both sides of the waste inlet 5 via sliding rails 11, allowing for manual opening and closing to prevent odor diffusion and enhance operational safety. The upper carbonization chamber 3 receives dry waste such as napkins, toilet paper, and sanitary napkins disposed of through the waste inlet 5, where it is carbonized through combustion. Simultaneously, an exhaust pipe 6 is installed on the top of the carbonization chamber, connecting the upper carbonization chamber 3 to the outside environment to exhaust the fumes generated during the carbonization process.

[0029] In addition, to ensure safety, such as Figure 4 As shown, in this embodiment, a high-temperature insulation board made of aluminum silicate fiberboard is also provided on the inner wall of the upper waste carbonization chamber 3. The high-temperature insulation board prevents heat loss and ensures the safe operation of the equipment.

[0030] The lower ash mixing chamber 4 is used to receive the carbonized ash, and it is also equipped with an ash mixing assembly for mixing the ash with water. Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the ash mixing assembly in this embodiment includes a mixing motor 13 and a mixing drum. The mixing motor 13 is installed outside the carbonization box; the mixing motor 13 is a commercially available finished product, such as a Shenzhen Huichuan MS1-H series micro AC geared motor with a power of 120W and a speed of 30rpm, suitable for intermittent mixing operations. The mixing drum includes a mixing shaft 14 rotatably mounted in the lower ash mixing chamber 4 via bearings, and a metal mesh cylinder 15 mounted on the mixing shaft 14. The output shaft of the mixing motor 13 is connected to the mixing shaft 14; after starting the mixing motor 13, the mixing shaft 14 drives the metal mesh cylinder 15 to rotate, thereby mixing the ash and water.

[0031] Considering the water inlet to the lower ash mixing chamber 4, and the discharge of the ash and water mixture; such as Figure 4 As shown, in this embodiment, the bottom rear side of the carbonization box is provided with a water inlet 7 that communicates with the lower ash mixing chamber 4, such as... Figure 1 , Figure 2 and Figure 3 As shown, a water inlet pipe 8 is installed outside the carbonization box through the water inlet 7. The water inlet pipe 8 is connected to an indoor faucet, allowing water to be injected into the lower ash mixing chamber 4. Additionally, as... Figure 4 As shown, in this embodiment, a drain outlet 9 is provided at the bottom of the carbonization box. A drain pipe 10 is installed outside the carbonization box through the drain outlet 9. The mixture of ash and water is discharged into the septic tank through the drain pipe 10, which can be used for biogas fermentation. Example 2

[0032] Based on Example 1, to further enhance the intelligence of this household dry waste intelligent processor, such as... Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, a control box 16 is also installed on top of the carbonization box. Meanwhile, as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a first solenoid valve 17 and a second solenoid valve 18 are installed at the water inlet 7 and the sewage outlet 9, respectively. A induced draft fan is installed on the exhaust pipe 6. The electrical control box is electrically connected to each electrically controlled valve, carbonization rod 2, induced draft fan, and the stirring motor 13 of the ash mixing assembly. The electrically controlled valves and induced draft fans are all commercially available finished products, such as: Shanghai Shenbei ZC22T-A normally closed solenoid valve, which has an automatic shut-off function in case of power failure to prevent water leakage; and Midea MF-120 miniature axial flow fan, which is used to quickly discharge the flue gas generated during the carbonization process, ensuring air circulation and reducing the accumulation of harmful gases.

[0033] The control box 16 integrates various electrical components, including: a commercially available Siemens S7-200 SMART ST20 miniature programmable controller; an Omron H3CR-AS4 digital time relay for setting carbonization and stirring times; a relay module for controlling the start and stop of the carbonization rod 2, the induced draft fan, the stirring motor 13, and the solenoid valve; a power module that converts mains power to DC 24V for the control system; a Kunlun Tongtai TPC7062KX touchscreen for parameter setting and status display; and an emergency stop button and alarm indicator lights for emergency stop and fault indication. The electrical connections of these components are conventional and will not be described in detail here.

[0034] When the user puts dry waste into the waste inlet 5, the PLC controller in the control box 16 starts the carbonization program. First, the induced draft fan is turned on, and air enters through the waste inlet 5 to establish a stable airflow environment; then the carbonization rod 2 starts to heat up, causing the waste to burn and carbonize, generating solid ash, and the flue gas generated during the process is discharged from the exhaust pipe 6. After carbonization is completed, the time relay triggers a signal to control the first solenoid valve 17 to open the water inlet 7, injecting an appropriate amount of clean water into the ash mixing chamber; at the same time, the stirring motor 13 drives the stirring drum to rotate, fully mixing the ash and water into a slurry; finally, the second solenoid valve 18 opens the sewage outlet 9, and the mixture is transported to the septic tank through the sewage pipe 10 for biogas fermentation.

[0035] 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.
