Description

Technical Field

[0001] The utility model relates to the technical field of solid waste treatment, and more specifically, to a high-efficiency solid waste treatment device. Background Art

[0002] Solid waste (abbreviated as solid waste) refers to solid, semi-solid and gaseous items and materials placed in containers that have lost their original utilization value or have not lost their utilization value but have been abandoned or discarded in the process of human production, life and other activities, as well as items and materials that are included in the management of solid waste according to laws and administrative regulations. With the rapid development of industrialization and urbanization, the amount of solid waste generated has shown an explosive growth trend. Its stacking requires a large amount of land area. If it is not properly handled, it will not only pollute the soil, water and air, but also may have a serious impact on human health. Therefore, solid waste treatment is not only the focus of environmental protection work, but also an inevitable requirement for achieving sustainable development; general solid waste treatment methods mainly include general storage, enclosure storage, landfill, incineration and biodegradation. The purpose of these methods is to recover and utilize resources from solid waste, realize waste resource utilization, turn waste into treasure, and improve the utilization rate of solid waste. When using incineration to burn solid waste, although the volume of waste can be greatly reduced, it is easy to have problems such as incomplete combustion and low combustion efficiency.

DETAILED DESCRIPTION

[0015] Reference Figure 1 The utility model is further described in detail.

[0016] A high-efficiency solid waste treatment device includes an incinerator 1 for burning solid waste, a pretreatment component is installed on the incinerator 1, the pretreatment component includes a crushing box 2 connected to the incinerator 1, an extrusion box 3 connected to the crushing box 2, a cylinder 301 installed in the extrusion box 3, and a motor 201 installed on the crushing box 2, a pressing plate 302 fixedly connected to the cylinder 301 and a placing plate 303 matched with the pressing plate 302 are provided in the extrusion box 3, the pressing plate 302 moves in the extrusion box 3 and cooperates with the placing plate 303 to form an extrusion space 304, the placing plate 303 cooperates with the extrusion box 3 to form a collection chamber 305, and an electric push rod 307 is installed on the extrusion box 3, and the electric push rod 307 extends into the extrusion box 3 The pressing plate 302 is provided with a push plate 308 fixedly connected to the output end of the electric push rod 307, and the push plate 308 moves on the placement plate 303. The placement plate 303 is provided with a plurality of drainage holes 3031 connected to the collecting chamber 305. The pressing box 3 is provided with a feed pipe 4 connected to the pressing space 304, a discharge pipe 5 connected to the pressing space 304 and the crushing box 2, and a drain pipe 306 connected to the collecting chamber 305. A valve is installed on the drain pipe 306. A telescopic pipe 401 connected to the feed pipe 4 is installed on the pressing plate 302. The telescopic pipe 401 is connected to the pressing space 304. A baffle 501 cooperating with the push plate 308 is hinged in the discharge pipe 5.

[0017] The shaft of the motor 201 extends into the crushing box 2 and is rotatably connected to the crushing box 2. A rotating rod 202 fixedly connected to the shaft of the motor 201 is provided in the crushing box 2. A plurality of crushing knives 203 are installed on the rotating rod 202. A heating element 204 is installed in the crushing box 2. A material guide pipe 6 with a solenoid valve is connected to the crushing box 2, and the material guide pipe 6 is connected to the incinerator 1.

[0018] Working principle: solid waste enters the extrusion space 304 from the feed pipe 4 through the telescopic tube 401 and is placed on the storage plate 303. The cylinder 301 drives the pressing plate 302 to approach the storage plate 303 and cooperates with the storage plate 303 to squeeze the solid waste in the extrusion space 304 to reduce the moisture in the solid waste, so that it is easier to enter the combustion furnace for subsequent combustion and improve the combustion speed. The telescopic tube 401 is extended and reciprocated with the pressing plate 302, so as not to affect the movement of the pressing plate 302 and not hinder the solid waste from entering the extrusion space 304. The squeezed water enters the collection chamber 305 through the drainage hole 3031 on the storage plate 303. The valve on the drainage pipe 306 can be opened to discharge the water accumulated in the collection chamber 305, so that the collection chamber 305 can continue to collect the water squeezed out of the solid waste by the pressing plate 302. The cylinder 301 drives the pressing plate 302 away from the placing plate 303 and the position of the pressing plate 302 in the extrusion box 3 is higher than the top position of the push plate 308, and the electric push rod 307 works to drive the push plate 308 to move on the placing plate 303 and approach the baffle 501, so that the solid waste that has been squeezed out of water is pushed into the discharge pipe 5 and then enters the crushing box 2. When the solid waste enters the discharge pipe 5, the solid waste collides with the baffle 501 under the push of the push plate 308, and the push plate 308 continues to move close to the baffle 501 so that the solid waste pushes the baffle 501 away, thereby facilitating the solid waste to enter the discharge pipe 5 and then enter the crushing box 2. The setting of the baffle 501 prevents the solid waste from falling directly into the crushing box 2 without being squeezed when entering the extrusion space 304 through the feed pipe 4, which affects the removal effect of water in the solid waste, is not conducive to the subsequent combustion of the solid waste, and affects the combustion efficiency.

[0019] After the solid waste enters the crushing box 2, the motor 201 drives the rotating rod 202 to rotate, so that the crushing knife 203 on the rotating rod 202 rotates to crush the solid waste, reducing the volume of the solid waste is conducive to subsequent full combustion, and the solenoid valve on the guide pipe 6 is controlled to open so that the solid waste with reduced volume after crushing in the crushing box 2 enters the incinerator 1 through the guide pipe 6 for combustion. The crushing knife 203 rotates to crush the solid waste and also breaks up the solid waste in agglomerates and blocks, which is convenient for the solid waste in the subsequent crushing box 2 to enter the combustion furnace for combustion. More fully, the heating element 204 works to heat the internal space of the crushing box 2, so as to heat and dry the solid waste in the crushing box 2, further reduce the moisture in the solid waste to facilitate subsequent combustion, improve the combustion efficiency, and avoid the small volume of crushed solid waste from being easily agglomerated due to excessive moisture, which may cause the guide pipe 6 to be blocked when entering the incinerator 1 through the guide pipe 6. It is highly practical. At the same time, the setting of the baffle 501 can also prevent a small part of the crushed small volume solid waste in the crushing box 2 from directly flying out of the discharge pipe 5 into the extrusion box 3 and unable to enter the incinerator 1 for combustion treatment.

[0020] Ultimately, the solid waste can be pre-treated through the extrusion box 3 and the crushing box 2 before it is burned, the moisture in the solid waste can be removed to speed up the burning speed of the solid waste, and the volume of the solid waste can be reduced to make the solid waste burn more fully, further improving the combustion efficiency and enhancing practicality.
