Description

Technical Field

[0001] This utility model belongs to the field of solid waste treatment technology, specifically, it relates to an environmentally friendly solid waste incineration treatment device. Background Technology

[0002] By incinerating solid waste, not only can energy be recovered and utilized, but the efficiency of solid waste treatment can also be improved. During the solid waste incineration process, a remotely operated robotic gripper feeds the solid waste into the incinerator. Then, the high-temperature heat generated by the combustion of solid waste is recovered and utilized under the action of the heat exchange equipment. Finally, the smoke is purified through multiple purification processes, including electrostatic precipitator, spray dryer, bag filter, and catalytic reactor.

[0003] When using robotic grippers to feed solid waste into the incinerator, the relatively fixed placement of the waste can easily lead to its accumulation. This accumulation hinders oxygen access during combustion, resulting in incomplete combustion. Incomplete combustion produces large amounts of harmful gases such as carbon monoxide and polycyclic aromatic hydrocarbons. Furthermore, the accumulation causes instability in the combustion process, leading to significant fluctuations in the flow rate and composition of the exhaust gas. This poses challenges to subsequent exhaust gas purification equipment. For example, it can reduce the dust collector's efficiency or make it difficult for the spray dryer to effectively absorb harmful gases. Since exhaust gas treatment equipment is typically designed for specific flow rates and pollutant concentration ranges, unstable combustion can exceed the equipment's optimal processing range, causing some pollutants to be untreated and directly released into the atmosphere, thus reducing the environmental friendliness of solid waste treatment.

[0004] In view of this, this utility model is proposed. Utility Model Content

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0025] Example 1

[0026] Please see Figures 1-6 The illustrated environmentally friendly solid waste incineration treatment device includes an incinerator, which is divided into a feeding chamber 101 and a combustion chamber 102 by a partition. The bottom walls of the feeding chamber 101 and the combustion chamber 102 are connected by an inclined plate 103. A smoke conveying pipe 104 is provided on the side of the combustion chamber 102 away from the feeding chamber 101. The device also includes a feeding component installed in the feeding chamber 101 for decentralized feeding of solid waste.

[0027] The feeding assembly includes a feeding frame 201 fixedly connected to the inner wall of the feeding chamber 101 at the feeding end. The inner wall of the feeding frame 201 is trapezoidal. The bottom wall of the feeding frame 201 has multiple feeding ports 202. Two sealing boxes 203 are fixedly connected to the two opposite side walls of the feeding frame 201. The two sealing boxes 203 are arranged through the feeding chamber 101. A flexible steel plate 204 is slidably connected between the two sealing boxes 203. The flexible steel plate 204 has through holes 205, which are matched with the feeding ports 202. The feeding chamber 101 is provided with a driving assembly for driving the flexible steel plate 204 and a turning assembly for turning the solid waste in the feeding frame 201.

[0028] It should be noted that, through the setting of the feeding component, the solid waste falls from different positions into the combustion chamber 102 under the combined action of the drive component, the rewind component, and the agitator component, thereby reducing the probability of solid waste accumulation and improving the completeness of combustion. This reduces the generation of harmful gases such as carbon monoxide and polycyclic aromatic hydrocarbons or their impact on the smoke purification equipment, thus improving the environmental friendliness of solid waste treatment.

[0029] It is worth noting that in the existing incineration process of solid waste, large solid waste is pre-crushed by crushing equipment, thereby reducing the volume of large solid waste and allowing it to pass through the feeding port 202 on the bottom wall of the feeding frame 201 without causing blockage.

[0030] Please see Figure 4 and Figure 6The driving assembly shown in the figure includes two symmetrically arranged first fixing plates 301 and second fixing plates 302 fixedly connected to the two inner walls of the feeding chamber 101. The two first fixing plates 301 and second fixing plates 302 are connected by a first rotating shaft and a second rotating shaft 306 to a first winding roller 303 and a second winding roller 304. The two ends of the flexible steel plate 204 are respectively connected to the first winding roller 303 and the second winding roller 304. One of the two second fixing plates 302 is provided with a winding assembly for winding the flexible steel plate 204. One of the two first fixing plates 301 is provided with a motor 305. The output end of the motor 305 is connected to the first rotating shaft.

[0031] It should be noted here that the drive component is designed to facilitate the reciprocating movement of the flexible steel plate 204, thereby enabling the through hole 205 to engage with the feeding port 202 at different positions and to block other feeding ports 202.

[0032] It is worth noting that the model number of motor 305 is Y80M1-2. As this is existing technology, we will not go into further detail here.

[0033] Please see Figure 4 and Figure 6 The rewind assembly shown in the figure includes a rewind plate 401 disposed on one side of the second fixed plate 302, one end of the second rotating shaft 306 passing through the second fixed plate 302 and connected to the rewind plate 401, and a torsion spring 402 sleeved on the side wall of the second rotating shaft 306, with both ends of the torsion spring 402 connected to the second fixed plate 302 and the rewind plate 401 respectively.

[0034] It should be noted that, through the setting of the rewinding assembly, when the first take-up roller 303 releases the flexible steel plate 204, the torsion spring 402 can drive the second take-up roller 304 to rewind the flexible steel plate 204, thereby ensuring the tightness of the flexible steel plate 204.

[0035] Working principle: When incinerating solid waste, a mechanical hand gripper first moves the solid waste to the feeding end of the feeding chamber 101, and then it falls into the feeding frame 201 under gravity. After the solid waste falls into the feeding frame 201, the motor 305 is started, driving the first winding roller 303 to rotate. During the rotation of the first winding roller 303, the flexible steel plate 204 will move. As the flexible steel plate 204 moves, the multiple feeding ports 202 on the bottom wall of the feeding frame 201 reciprocate with the through holes 205 on the flexible steel plate 204. The combination of different feeding ports 202 and through holes 205 allows solid waste to be fed into the bottom wall of the feeding chamber 101 from different locations. Under the guidance of the inclined plate 103, the solid waste flows into the combustion chamber 102 for combustion. By allowing the solid waste to fall into the combustion chamber 102 from different locations, the probability of solid waste accumulation is reduced, thereby improving the completeness of combustion of solid waste. This reduces the generation of harmful gases such as carbon monoxide and polycyclic aromatic hydrocarbons or their impact on the smoke purification equipment, thus improving the environmental friendliness of solid waste treatment.

[0036] During the combustion process of solid waste in combustion chamber 102, the high-temperature heat generated by the combustion of solid waste is recovered and utilized under the action of the heat exchange equipment. Finally, the smoke is purified through multiple purification processes including electrostatic precipitator, spray dryer, bag filter and catalytic reactor. The heat utilization and smoke purification during the combustion process of solid waste are existing technologies and will not be elaborated on here.

[0037] Example 2

[0038] Please see Figure 4 This embodiment further illustrates Example 1. The actuating assembly shown in the figure includes a sliding plate 501 slidably connected to the feeding chamber 101. A plurality of actuating rods 502 are fixedly connected to the side of the sliding plate 501 near the feeding frame 201. A conical head is fixedly connected to the end of each actuating rod 502 away from the sliding plate 501. A guide rod 503 and a threaded rod 504 are provided between two opposing inner walls of the feeding chamber 101. The two ends of the sliding plate 501 are respectively adapted to be connected to the guide rod 503 and the threaded rod 504. The adapted connection means that the sliding plate 501 is slidably connected to the guide rod 503 and threadedly connected to the threaded rod 504. The feeding chamber 101 is provided with a rotating assembly for rotating the threaded rod 504.

[0039] It should be noted that: by setting up the actuating component, the rotating component drives the threaded rod 504 to rotate. Then, under the threaded meshing transmission between the threaded rod 504 and the sliding plate 501 and the guiding action of the guide rod 503, the sliding plate 501 moves within the feeding frame 201. This, in turn, drives each actuating rod 502 to move the solid waste in the feeding frame 201, thereby improving the uniformity of the distribution of fixed waste within the feeding frame 201, and thus improving the uniformity of material feeding for the decentralized disposal of solid waste.

[0040] Please see Figure 1 and Figure 3 The rotating assembly shown in the figure includes two third fixed plates 601 fixedly connected to the side of the feeding chamber 101 near the first winding roller 303. A worm gear 602 is connected between the two third fixed plates 601 through a third rotating shaft. One end of the threaded rod 504 passes through the feeding chamber 101 and is fixedly connected to a worm wheel 603. The worm wheel 603 and the worm gear 602 are meshed with each other. The end of the first rotating shaft away from the motor 305 is connected to the third rotating shaft through a gear 604 and a toothed belt 605.

[0041] It should be noted that, through the arrangement of the rotating components, during the rotation of the motor 305, the worm 602 on the third rotating shaft is driven to rotate by the transmission action of the gear 604 and the toothed belt 605. In turn, the worm 602 and the worm wheel 603 mesh and drive the threaded rod 504 to rotate. Thus, the rotational power of the motor 305 drives the threaded rod 504 to rotate, thereby maximizing energy utilization and reducing power costs.
