Technical Field
[0001] This utility model relates to the field of waste incineration power generation slag drum screening, and more specifically to a waste incineration power generation slag drum screening device. Background Technology
[0002] With the acceleration of urbanization, the amount of urban domestic waste generated is increasing year by year. Waste-to-energy incineration, due to its advantages of volume reduction, harmlessness, and resource recovery, has become one of the mainstream waste treatment methods in my country. During the waste-to-energy incineration process, slag is generated from the processing of domestic waste. Although most harmful components have been removed from this slag, it still contains unburned organic matter, glassy molten material, and metallic impurities. Further processing is required for resource utilization or safe disposal. Therefore, a waste-to-energy incineration slag drum screening device is needed. However, existing waste-to-energy incineration slag drum screening devices are not suitable for regularly cleaning the inner surface of the drum during screening, thus reducing the impact of slag adhesion on the drum's inner surface and affecting screening quality.

Detailed Implementation
[0018] A waste incineration power generation slag drum screening device includes a base 101 and multiple guide wheels 102 rotatably connected to the left and right sides of the base 101 and arranged circumferentially. Each guide wheel 102 has a slot in the middle. A side plate 202 is rotatably connected in the slot of each guide wheel 102. A drum 201 is fixedly connected to the middle of the two side plates 202. Multiple screen holes are evenly arranged on the drum 201 along the circumferential direction. A lifting limit frame 104 is fixedly connected to the left side of the base 101. A lifting frame 501 is slidably connected to the lifting limit frame 104. A long bar 502 is rotatably connected to the upper side of the lifting frame 501. A grinding roller 503 is fixedly connected to the right side of the long bar 502.
[0019] This section is based on Figure 1-8The working process described is as follows: During the slag drum screening of waste incineration power generation furnace, in order to facilitate regular cleaning of the inner surface of the drum and reduce the impact of slag adhesion on the inner surface of the drum on the screening quality, the waste is introduced into the drum 201 during use. The drum 201 rotates in the slots of multiple guide wheels 102 on both sides of the base 101 by relying on the side plates 202 on both sides. The rotating drum 201 screens the slag through the screen holes located on the drum 201. However, after screening the slag through the drum 201 for a long time, it is inevitable that slag will adhere to the inner surface of the drum 201. To solve the problem of slag adhesion, in the initial position, the grinding roller 503 on the long bar 502 is located in the upper part of the inner side of the drum 201. The left side of 02 is fixedly connected to the output shaft of a motor via a coupling. The motor is fixedly mounted on the lifting frame 501 by bolts. When it is necessary to clean the slag adhering to the inner surface of the drum 201, the drive motor causes the long bar 502 to rotate, thereby causing the grinding roller 503 located on the long bar 502 to rotate synchronously. At this time, the lifting frame 501 rises, and the rotating grinding roller 503 rises synchronously until the grinding roller 503 contacts the inner surface of the drum 201. Furthermore, when the drum 201 rotates, its inner surface contacts the rotating grinding roller 503 synchronously, and the inner surface of the drum 201 is ground and cleaned when the grinding roller 503 rotates. This facilitates the regular cleaning of the inner surface of the drum, thereby reducing the impact of slag adhesion on the inner surface of the drum on the screening quality.
[0020] Each slot on the guide wheel 102 is polished. This part is based on... Figure 1-8 The working process described is as follows: each slot on the guide wheel 102 is polished to reduce the friction between the slot on the guide wheel 102 and the side plates 202 on both sides of the roller 201, which helps the roller 201 rotate more stably.
[0021] The grinding roller 503 has multiple elongated teeth evenly distributed along its circumference. This part is based on... Figure 1-8 The working process described is as follows: multiple long teeth are evenly arranged on the grinding roller 503 along the circumferential direction, so that the friction between the grinding roller 503 and the inner surface of the roller 201 can be increased by rotating the grinding roller 503 and utilizing the long teeth, thereby increasing the quality of cleaning the inner surface of the roller 201.
[0022] The bottom of the lifting frame 501 is fixedly connected to the movable end of the electric push rod 504, and the fixed end of the electric push rod 504 is fixedly connected to the bottom left side of the lifting limit frame 104. This part is based on... Figure 1-8The working process described is as follows: when the lifting frame 501 is controlled to lift, the electric push rod 504 is driven to make the lifting frame 501 located on the movable end of the electric push rod 504 move up and down on the lifting limit frame 104, thereby helping to control the degree to which the grinding roller 503 is attached to the inner surface of the roller 201.
[0023] A toothed ring 203 is fixedly connected to the left side of the roller 201. Multiple teeth are evenly distributed along the circumferential direction on the edge of the toothed ring 203. A crossbar 105 is rotatably connected to the top front side of the base 101. A gear 106 is fixedly connected to the middle of the crossbar 105, and the gear 106 meshes with the teeth on the toothed ring 203 for transmission. This part is based on... Figure 1-8 The working process described is as follows: When the control drum 201 rotates, the output shaft of a second motor is fixedly connected to one side of the crossbar 105 through a coupling. The second motor is fixedly installed on the base 101 by bolts. The second motor drives the crossbar 105 to rotate, thereby rotating the gear 106 located on the crossbar 105. The rotation of the gear 106 causes the gear ring 203 connected to it through gear meshing to rotate synchronously. Thus, the gear ring 203 drives the drum 201 to rotate, and performs slag screening.
[0024] A square tube is fixedly connected to the bottom right side of the base 101. The bottom of a sliding frame 301 is slidably connected inside the square tube. A feed box 302 is fixedly connected to the upper side of the sliding frame 301. A discharge port extending downwards to the left is located on the bottom left side of the feed box 302. A handle is fixedly connected to the middle of the right side of the sliding frame 301. This part is based on... Figure 1-8 The working process described is as follows: when the slag flows into the drum 201, the top of the feed box 302 is aligned with the slag flow position, and simultaneously, the user grasps the handle on one side of the feed box 302 to extend the bottom left outlet of the feed box 302 into the drum 201, so that the slag flows into the drum 201. Then, the slag is screened by the rotation of the drum 201.
[0025] A guide rail 103 is fixedly connected to the left and right sides of the bottom of the base 101. A side piece 402 is slidably connected within each guide rail 103. The two side pieces 402 are fixedly connected to the left and right sides of the bottom of the receiving box 401. A handle 403 is fixedly connected to the rear side of the receiving box 401. Openings are provided at the rear of the two guide rails 103. This part is based on... Figure 1-8The working process described is as follows: When collecting the material screened out by the drum 201, the user grasps the handle 403 on the receiving box 401 and slides it in the two guide rails 103 by relying on the side plates 402 on both sides of the receiving box 401, so that the receiving box 401 slides to the bottom of the drum 201 to collect the screened material. Then, the receiving box 401 can be pulled out from the two guide rails 103 with two rear openings, and the screened material is collected and processed.
