Description

Technical Field

[0001] This utility model relates to the field of waste incineration power generation technology, specifically a thermal power generation device for waste incineration power generation. Background Technology

[0002] In the process of urbanization, garbage, as a product of urban metabolism, was once a burden on urban development. Garbage incineration is a process in which garbage is reduced in volume through appropriate thermal decomposition, combustion and melting reactions, and then oxidized at high temperatures to become residue or molten solid matter. The heat generated by garbage incineration is used to generate electricity and improve resource utilization.

[0003] Existing thermal power generation devices for waste incineration power generation have low crushing efficiency, which can easily cause blockages in the conveyor, affecting the discharge of waste materials and resulting in incomplete incineration and reduced power generation efficiency. In addition, the subsequent emissions generally contain a lot of dust, which is not easy to handle. Therefore, we propose a thermal power generation device for waste incineration power generation. Utility Model Content

[0004] The purpose of this invention is to provide a thermal power generation device for waste incineration power generation, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a thermal power generation device for waste incineration power generation, comprising a first body, a conveying component, a second body, and a protective component. The conveying component is provided at the bottom of the interior of the first body, and the second body is provided at the end of the conveying component. The protective component is provided at the middle of the side of the second body. The first body includes a first frame, a torsion spring shaft, a baffle plate, and a crushing roller. The torsion spring shaft is provided on both sides of the top of the first frame, and the baffle plate is provided on the side of the torsion spring shaft. The crushing roller is provided inside the first frame.

[0006] Furthermore, the cover plate is symmetrically arranged along the first frame, and the cover plate is connected to the torsion spring shaft.

[0007] Furthermore, the conveying assembly includes a guide tube, a motor, and a screw shaft, with the motor located on one side of the guide tube and the screw shaft located at the tip of the motor.

[0008] Furthermore, the spiral shaft forms a transmission structure with the motor and the guide tube, and the guide tube is connected to the second body.

[0009] Furthermore, the second body includes a combustion chamber, an air intake pipe, a steam chamber, a steam pipe, and a first exhaust pipe. An air intake pipe is provided on one side of the bottom end of the combustion chamber, a steam chamber is provided on the top end of the combustion chamber, a steam pipe is provided on one side of the top end of the steam chamber, and a first exhaust pipe is provided on the other side of the top end of the steam chamber.

[0010] Furthermore, the protective assembly includes a second exhaust pipe, a valve body, a frame, and a filter screen, with the valve body located on the side of the second exhaust pipe, the frame located on the side of the valve body, and the filter screen located inside the frame.

[0011] Furthermore, the filter screen is fitted into the box frame, and the box frame is matched with the valve body.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: when the garbage material is put into the first machine body, the cover plate covers it, the internal crushing roller squeezes and crushes the garbage, and then it falls and is discharged by the bottom spiral shaft, moving it to the combustion chamber, so that the heat energy generated is used to heat water to generate steam, which in turn drives the subsequent steam turbine to generate electricity. Since the second exhaust pipe directly discharges gas, it is easy to generate a lot of dust. Therefore, a filter screen is set to filter the gas, so that the dust is retained in the filter screen box frame. The box frame is bolted, which is convenient for subsequent disassembly, replacement and maintenance.

[0013] The cover is located at the top of the first frame and is connected by a torsion spring shaft. When the waste material is put into the first machine body, the cover will open to both sides due to the weight. When all the waste falls into the first frame, the torsion spring shaft will reset the cover through its own elastic structure, making it close to prevent the waste material from splashing during crushing and thus increasing the safety hazard. The built-in crushing roller can squeeze and crush the waste to improve the subsequent incineration efficiency.

[0014] The intake pipe on one side of the combustion chamber ensures complete combustion, while the second exhaust pipe on the other side is used to expel the combustion gases. However, directly expelling gases from the second exhaust pipe can easily generate a lot of dust. Therefore, a filter screen is installed in the middle to filter the gas, causing dust to be trapped in the filter screen's frame. The filter screen is closed by a valve, allowing the frame to be removed and the filter screen taken out for cleaning. Subsequent filter screen replacements are done by bolting the frame together, facilitating subsequent disassembly and maintenance by staff. Attached Figure Description

[0019] like Figure 1-2As shown, a thermal power generation device for waste incineration power generation includes a first body 1, a conveying assembly 2, a second body 3, and a protective assembly 4. The conveying assembly 2 is located at the bottom of the interior of the first body 1, and the second body 3 is located at the end of the conveying assembly 2. The protective assembly 4 is located at the middle of the side of the second body 3. The first body 1 includes a first frame 101, a torsion spring shaft 102, a cover plate 103, and a crushing roller 104. The torsion spring shaft 102 is located on both sides of the top of the first frame 101, and the cover plate 103 is located on the side of the torsion spring shaft 102. The crushing roller 104 is located inside the first frame 101, and the cover plate 103 is symmetrically arranged along the first frame 101. Plate 103 is connected to torsion spring shaft 102. The cover plate 103 is located at the top of the first frame 101 and is connected via torsion spring shaft 102. When waste is fed into the first machine body 1, the cover plate 103 opens to both sides due to the weight. When all the waste falls into the first frame 101, the torsion spring shaft 102, without any weight contacting it, resets the cover plate 103 through its elastic structure, closing it to prevent splashing of waste during crushing and thus avoid increasing safety hazards. The built-in crushing roller 104 can squeeze and crush the waste, improving subsequent incineration efficiency. The conveying assembly 2 includes a guide tube 201, a motor 202, and a screw shaft 203. A motor 202 is installed on one side of the guide tube 201, and a spiral shaft 203 is installed at the tip of the motor 202. The spiral shaft 203 and the guide tube 201 form a transmission structure through the motor 202. The guide tube 201 is connected to the second machine body 3. After the waste material is crushed by the crushing roller 104, it falls into the guide tube 201. The motor 202 drives the spiral shaft 203 to rotate and discharge the material. The guide tube 201 is connected to the end combustion chamber 301 to facilitate the discharge of the crushed waste from the guide tube 201. The rotation of the spiral shaft 203 can be used to unclog the guide tube 201 to prevent blockage. The second machine body 3 includes a combustion chamber 301, an air inlet pipe 302, and a steam... The combustion chamber 301 has a steam chamber 303, a steam pipe 304, and a first exhaust pipe 305. An air inlet pipe 302 is provided on one side of the bottom end of the combustion chamber 301, and a steam chamber 303 is provided at the top end of the combustion chamber 301. A steam pipe 304 is provided on one side of the top end of the steam chamber 303, and a first exhaust pipe 305 is provided on the other side of the top end of the steam chamber 303. The top end of the combustion chamber 301 is the steam chamber 303. A water source is provided inside the steam chamber 303. Waste flows to the combustion chamber 301 through the guide pipe 201. Then, the temperature of the combustion chamber 301 is increased to heat the water source in the top steam chamber 303 to form steam. The steam flows to the subsequent steam turbine through the top steam pipe 304, thereby performing power generation operation.

[0020] like Figure 3As shown, a thermal power generation device for waste incineration power generation includes a protective component 4 comprising a second exhaust pipe 401, a valve body 402, a frame 403, and a filter screen 404. The valve body 402 is located on the side of the second exhaust pipe 401, and the frame 403 is located on the side of the valve body 402. The filter screen 404 is installed inside the frame 403, and the filter screen 404 is fitted into the frame 403. The frame 403 also cooperates with the valve body 402. The air intake pipe 302 on one side of the combustion chamber 301 ensures complete combustion inside. Conversely, the second exhaust pipe 401 on the other side is used to exhaust the combustion gases. However, the direct exhaust of gases from the second exhaust pipe 401 can easily generate a large amount of dust. Therefore, a filter screen 404 is installed in the middle to filter the gas, causing the dust to be trapped in the filter screen 404's frame 403. The frame 404 is closed by the valve body 402, allowing the frame 403 to be removed and the filter screen 404 to be taken out. After cleaning, the filter screen 404 can be replaced later by bolting the frame 403 together, which facilitates subsequent disassembly and maintenance by the staff.

[0021] Working principle: First, the cover plate 103 is set at the top of the first frame 101 and connected by the torsion spring shaft 102. When the waste material is put into the first machine body 1, the cover plate 103 will open to both sides when it is subjected to the weight. Then, when there is no weight in contact, the torsion spring shaft 102 resets the cover plate 103 through its own elastic structure, so that it closes to prevent the waste material from splashing during crushing. The built-in crushing roller 104 can squeeze and crush the waste.

[0022] Subsequently, the waste material falls into the guide tube 201, and the screw shaft 203 is rotated by the motor 202 to discharge the material. The guide tube 201 is connected to the end combustion chamber 301, and the crushed waste is discharged from the guide tube 201 and moved to the combustion chamber 301 by the rotation of the screw shaft 203.

[0023] The top of the combustion chamber 301 is the steam chamber 303, which is equipped with a water source. Waste flows to the combustion chamber 301 through the guide pipe 201. Then, the temperature of the combustion chamber 301 is increased to heat the water source in the top steam chamber 303 to form steam, which flows to the subsequent steam turbine power generation operation through the top steam pipe 304.

[0024] The intake pipe 302 on one side of the combustion chamber 301 ensures complete combustion, while the second exhaust pipe 401 on the other side is used to exhaust the combustion gases. Since the second exhaust pipe 401 can easily generate a lot of dust by directly exhausting the gas, a filter screen 404 is installed in the middle to filter the gas and trap the dust in the frame 403 of the filter screen 404. The frame 403 is closed by the valve body 402, and the filter screen 404 is removed by disassembling the frame 403 and then cleaned. The filter screen 404 is then replaced and placed in the frame 403 by bolts, which facilitates the subsequent disassembly and maintenance by the staff.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
