Description

Technical Field

[0001] This application relates to the field of waste disposal, and in particular to a waste feeding device. Background Technology

[0002] In the field of waste management, with the acceleration of urbanization and population growth, the amount of waste generated is increasing daily, making effective waste treatment crucial. Waste incineration, as a common waste treatment method, can reduce waste volume to a certain extent while simultaneously achieving energy recovery and utilization, thus occupying an important position in the waste management industry. It not only helps alleviate the land pressure caused by landfills but also generates electricity through the heat produced during incineration, creating economic value for society. Furthermore, the continuous development and improvement of waste incineration technology has also improved the efficiency and environmental protection level of waste management to a certain extent.

[0003] Waste feeding is a crucial step in the waste incineration process. Traditional waste feeding methods typically involve conveyor belts. While conveyor belts can control the amount and speed of waste transported to the incinerator feed inlet to some extent, for waste containing moisture, the moisture will enter the incinerator along with the waste, increasing the difficulty and cost of incineration. Utility Model Content

[0004] To reduce the difficulty and cost of incineration, this application provides a waste feeding device.

[0005] The waste feeding device provided in this application adopts the following technical solution: A waste feeding device includes a conveying pipe for conveying waste and a feeding pipe for connecting to an incinerator. An auger is rotatably connected inside the conveying pipe. One end of the feeding pipe is fixed to and connected to one end of the conveying pipe. A plurality of water-permeable holes are provided on the lower side of the end of the conveying pipe near the feeding pipe. A water collection tank covering the plurality of water-permeable holes is fixedly connected to the outer wall of the conveying pipe.

[0006] By adopting the above technical solution, the auger in the conveying pipe can convey the waste, the feed pipe is connected to the conveying pipe so that the waste can enter the incinerator, the water permeable hole on the lower side of the conveying pipe can drain the water in the waste, and the water collection tank can collect the drained water, preventing sewage from flowing everywhere and reducing the difficulty and cost of incineration.

[0007] Preferably, a flange is fixedly connected to one end of the water collection tank near the conveying pipe, and the flange is detachably connected to the conveying pipe.

[0008] By adopting the above technical solution, an auger is installed inside the conveying pipe to convey garbage. A water-permeable hole is opened on the lower side of the conveying pipe near the feed pipe, and a water collection tank is installed on the outside to collect water seeping out of the garbage. The water collection tank is detachably connected to the conveying pipe through a flange, which facilitates the disassembly and installation of the water collection tank and makes it convenient for cleaning, maintenance or replacement of the water collection tank.

[0009] Preferably, an elastic sealing ring is fixedly connected between the flange and the transmission pipe.

[0010] By adopting the above technical solution, the elastic sealing ring can be fixedly connected between the flange and the transmission pipe, which can enhance the sealing performance of the connection between the water collection tank and the transmission pipe and reduce the occurrence of water leakage.

[0011] Preferably, the lower end of the water collection tank is fixed and connected to a water inlet pipe.

[0012] By adopting the above technical solution, the moisture in the garbage in the conveying pipe flows into the water collection tank through the water permeable holes. The water inlet pipe fixed and connected to the lower end of the water collection tank can draw out the water in the water collection tank, which facilitates the centralized treatment of the moisture in the garbage.

[0013] Preferably, the water collection tank is a funnel-shaped water collection tank.

[0014] By adopting the above technical solution, the funnel-shaped water collection tank can more smoothly collect water into the water inlet pipe for discharge.

[0015] Preferably, the conveying pipe includes two straight pipe sections, one of which is connected to the feed pipe, and a connecting pipe section is fixedly connected between the two straight pipe sections. The water permeable hole is opened in the connecting pipe section, and the inner diameter of the connecting pipe section gradually decreases along the direction close to the feed pipe.

[0016] By adopting the above technical solution, it is easy for the moisture in the waste to be discharged through the permeable holes; the inner diameter of the connecting pipe section gradually decreases along the direction close to the feed pipe. As the waste moves towards the feed pipe, the smaller inner diameter of the connecting pipe section will squeeze the waste, further promoting the discharge of moisture from the waste and improving the waste dehydration effect. At the same time, it can also make the waste more compact, making it easier to enter the incinerator for subsequent processing.

[0017] Preferably, the auger includes an auger shaft rotatably connected inside the conveying pipe and auger blades fixed around the auger shaft, and a plurality of cutting blades are fixedly connected to one end of the auger shaft near the feed pipe.

[0018] By adopting the above technical solution, the auger in the conveying pipe can convey garbage, and the multiple cutting blades on the auger shaft near the feed pipe end can cut the garbage, making it easier for the garbage to enter the incinerator for subsequent processing. The whole system realizes the functions of garbage conveying and cutting.

[0019] Preferably, the cutting blade has cutting edges on both sides.

[0020] By adopting the above technical solution, the cutting edges on both sides of the cutting blade can achieve cutting function in both directions, thereby improving cutting efficiency.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. It removes moisture from the waste, reducing the difficulty and cost of incineration; 2. As the waste moves into the feed pipe, the inner diameter of the connecting pipe section decreases, which will squeeze the waste and further promote the discharge of water from the waste; 3. The waste is cut into pieces to facilitate its subsequent entry into the incinerator for processing. Attached Figure Description

[0025] The following is in conjunction with the appendix Figures 1-2 This application will be described in further detail.

[0026] This application discloses a waste feeding device. (Refer to...) Figure 1 and Figure 2 The waste feeding device includes a conveying pipe 1 for conveying waste and a feed pipe 2 for connecting to an incinerator. The conveying pipe 1 conveys waste horizontally, and one end of the feed pipe is fixed to and connected to one end of the conveying pipe 1. The end of the conveying pipe 1 away from the feed pipe gradually extends and connects to the waste pool. The feed pipe 2 is located below the conveying pipe 1 and is arranged vertically.

[0027] Several water-permeable holes 3 are provided on the lower side of the end of the conveying pipe 1 near the feed pipe 2. A water collection tank 4 is fixedly connected to the outer wall of the conveying pipe 1. The upper end of the water collection tank 4 is open, and the several water-permeable holes 3 are covered inside. This arrangement allows water to flow into the water collection tank 4 through the water-permeable holes 3 during the waste conveying process, thereby removing moisture from the waste and reducing the possibility of large amounts of water entering the incinerator, increasing fuel consumption, and causing damage to the equipment.

[0028] Reference Figure 1 and Figure 2 An auger 5 is rotatably connected inside the conveying pipe 1. The auger 5 includes an auger shaft 51 rotatably connected inside the conveying pipe 1 and auger blades 52 fixed around the auger shaft 51. A drive motor is fixedly connected to the outer wall of one end of the conveying pipe 1, and the output shaft of the drive motor is fixedly connected to the auger shaft 51. The auger shaft 51 is usually made of metal and has a certain strength and wear resistance to ensure that it can stably drive the auger blades 52 during rotation. The auger blades 52 are spirally wound around the auger shaft 51, and their shape and pitch can be designed according to the actual waste conveying requirements. For example, for waste with good flowability, blades with a larger pitch can be used; for waste with high viscosity, blades with a smaller pitch can be used. In some special cases, the auger shaft 51 can also be made of materials with special properties such as ceramics to enhance its corrosion resistance.

[0029] The screw shaft 51 and the conveying pipe 1 can be rotated by bearings. Bearings can reduce friction during rotation and improve the rotation efficiency of screw 5.

[0030] Reference Figure 1 and Figure 2 The conveying pipe 1 includes two straight pipe sections 11, with a connecting pipe section 12 fixedly connected between them. The diameter of one straight pipe section 11 is smaller than that of the other, and the smaller diameter straight pipe section 11 is connected to the feed pipe 2. The inner diameter of the connecting pipe section 12 gradually decreases towards the feed pipe 2, and a water permeable hole 3 is formed on the lower side wall of the connecting pipe section 12. When the waste is conveyed by the auger 5 through the connecting pipe section 12, the inner diameter of the connecting pipe section 12 can exert a certain squeezing effect on the waste, further promoting the extrusion of water. The water permeable hole 3 is formed in the connecting pipe section 12.

[0031] A flange 41 is fixedly connected to one end of the water collection tank 4 near the transmission pipe 1. The flange 41 is fastened to the transmission pipe 1 with bolts. This connection method facilitates the disassembly and replacement of the water collection tank 4 when it malfunctions or needs cleaning. Simultaneously, an elastic sealing ring 42 is fixedly connected between the flange 41 and the transmission pipe 1. The elastic sealing ring 42 is generally made of elastic materials such as rubber, and its function is to limit water leakage from the connection between the flange 41 and the transmission pipe 1. When installing the elastic sealing ring 42, it is necessary to ensure its good sealing performance, which can be further enhanced by applying sealant.

[0032] The lower end of the water collection tank 4 is fixed and connected to a water inlet pipe 6, and a valve is installed on the water inlet pipe 6. The water inlet pipe 6 is used to drain the water collected in the water collection tank 4. The water collection tank 4 is funnel-shaped, which allows the collected water to drain more smoothly along the water inlet pipe 6, reducing the amount of water remaining in the water collection tank 4.

[0033] Multiple cutting blades 7 are fixedly connected to one end of the auger shaft 51 near the feed pipe 2. The cutting blades 7 are generally made of metal and have sharp edges, capable of cutting and crushing larger volumes of waste, allowing for more complete combustion after entering the incinerator. The cutting blades 7 have blades on both sides to improve cutting efficiency and flexibility. The number and shape of the cutting blades 7 can be adjusted according to the characteristics of the waste and processing requirements; for example, for harder waste, the number of cutting blades 7 can be increased or a sharper blade shape can be used.

[0034] The implementation principle of the waste feeding device in this embodiment is as follows: The waste feeding device conveys waste by rotating the auger 5 inside the conveying pipe 1. During the conveying process, the change in the inner diameter of the connecting pipe section 12 squeezes the waste, causing the moisture in the waste to flow into the water collection tank 4 through the water permeable holes 3, and then be discharged through the water inlet pipe 6. This effectively removes the moisture from the waste, reduces the difficulty and cost of incineration, and protects the incinerator equipment. At the same time, the cutting blade 7 at the end of the auger shaft 51 can pre-cut larger volumes of waste, allowing for more complete combustion of the waste in the incinerator. In addition, the water collection tank 4 is detachably connected to the conveying pipe 1 via a flange 41, facilitating equipment maintenance and cleaning.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
