Description

Technical Field

[0001] The present invention relates to the technical field of waste treatment equipment, and in particular to a rolling shear type grate incineration equipment. Background Art

[0002] Incineration is an effective way to treat waste. The currently widely used waste incineration equipment is an incinerator. The incinerators on the market are mainly divided into the following forms:

[0003] A fixed-bed incinerator, where the materials are burned on a fixed furnace bed, suitable for treating waste with large quantities and stable compositions; a fluidized-bed incinerator, where the materials are made to form a fluidized state in the furnace through high-speed air flow, with high combustion efficiency but relatively high energy consumption; a rotary kiln incinerator, where the materials are burned in a rotating kiln body, suitable for treating various types of waste, but with a complex structure and high maintenance costs.

[0004] Although the above incinerators can meet the waste treatment requirements to a certain extent, there is generally a technical problem, that is, it is impossible to balance the degree of material combustion and energy consumption. The specific manifestations are as follows: Due to design or operation reasons, some incinerators cause incomplete combustion of the materials. In order to ensure complete combustion of the materials, some incinerators need to consume a large amount of power energy to turn the materials, increasing the operating cost. To solve the above technical problems, a person skilled in the art proposed a grate incinerator with a reciprocating grate roller tray type with the application number 201811096393.5. Multiple grate rollers continuously stir the waste. The waste falls from the feed port into the topmost tray and passes through each layer of trays from top to bottom, which not only promotes the sufficiency of combustion but also realizes low-energy consumption operation. However, in actual operation, a jamming problem is likely to occur, that is, the grate rollers are easily jammed by the waste. For example, during the incineration process, some waste may accumulate between the grate rollers and the trays due to incomplete combustion or irregular shapes, causing jamming. This problem not only affects the continuous operation efficiency of the equipment but also increases the maintenance cost and operation complexity. Summary of the Invention

[0041] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be clear that the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0042] As Figure 1-7 shown, in some illustrative embodiments, a rolling shear type grate incineration device is provided, including: a furnace body frame 1, a furnace wall 2, a secondary combustion chamber 3, a heat exchanger 4, a blower 5, a burner 6, a material carrier plate 7, a ventilation beam 8, a pusher assembly, a clamping machine adjustment module, a feedback adjustment module, and a power mechanism.

[0043] The furnace body frame 1 and the furnace wall 2 together form the furnace body of the grate incineration device. Among them, the furnace body frame 1 is arranged on the furnace wall 2, and it is a frame structure formed by welding a plurality of hollow tubes, that is, spliced and welded by a plurality of horizontally and vertically arranged hollow tubes. Steel tubes can be selected for the hollow tubes, and the selection of steel tubes can ensure that the furnace body can still maintain a certain strength in a high-temperature incineration environment. The furnace body frame 1 serves two purposes. One is to support the entire furnace body to ensure the stability of the furnace body. The other is to form an air delivery channel, that is, the interiors of the hollow tubes communicate with each other to form an air delivery channel. The air flow network formed by this air delivery channel can introduce external air into the combustion chamber 21 to supplement oxygen for the combustion of waste materials and ensure the combustion effect. The furnace wall 2 encloses a closed combustion space, that is, the combustion chamber 21, and the incineration of waste materials is carried out in the combustion chamber 21. The furnace wall 2 is made of refractory materials, and the refractory materials need to have high temperature resistance, corrosion resistance and heat insulation properties.

[0044] The furnace body frame 1 is fixedly connected to the furnace wall 2 to jointly form the furnace body structure of the grate incineration device. The furnace body frame 1 not only realizes the support function but also forms an air delivery channel to provide sufficient oxygen supply for the combustion of waste materials in the combustion chamber 21. The synergistic effect of the two ensures that the incineration device operates in an efficient, stable and safe state, realizing the efficient incineration of waste materials.

[0045] The material carrier plate 7 is used to carry waste materials, and the number is at least three to achieve multi-layer and multi-stage continuous incineration. Moreover, the material carrier plates 7 are arranged in a staggered form and are sequentially arranged in the combustion chamber 21 from top to bottom. The staggered arrangement form can achieve the continuous layer-by-layer combustion of waste materials and the efficient segmented treatment. Among them, the staggered arrangement form of the material carrier plate 7 means that the suspension ends of two adjacent material carrier plates 7 face the two side walls of the combustion chamber 21 respectively. There is a certain distance between the suspension end of the material carrier plate 7 and the chamber wall of the combustion chamber 21 to form a blanking port 22, so that the incinerated waste materials or incompletely burned waste materials on the current layer of the material carrier plate 7 can fall onto the material carrier plate 7 of the next layer through the blanking port 22 and continue the next-stage incineration treatment.

[0046] The material carrier plate 7 is supported and carried by the ventilation beam 8. Specifically, both ends of the ventilation beam 8 are embedded in the furnace wall 2 and welded to the furnace body skeleton 1, and the inside of the ventilation beam 10 is hollow and connected to the gas transmission channel inside the furnace body skeleton 1.

[0047] Installation slots 23 are opened on the furnace wall 2, and installation slots 23 are opened on the furnace wall 2 above both sides of each material carrier plate 7. The burner 6 is arranged in the installation slot 23 and is used to burn the waste materials, that is, the burner 6 can provide the heat source required for incineration, generate high-temperature flames by burning fuel, heat and incinerate the waste materials, and the number of burners 6 put into use and the flame size and temperature of each burner 6 can be adjusted according to the different incineration requirements of different waste materials at each stage.

[0048] A set of pusher components is arranged above each material carrier plate 7. The pusher components are used to push the waste materials to realize the movement of the waste materials on the material carrier plate 7. Through the continuous pushing of the pusher components, the waste materials are gradually pushed towards the blanking port 22 until they fall through the blanking port 22 onto the material carrier plate 7 of the next layer. The combination of the staggered arrangement form of the material carrier plate 7 and the pushing function of the pusher components enables the waste materials to move evenly on the material carrier plate 7 and fall layer by layer under the pushing of the pusher components, forming an efficient and continuous waste incineration treatment process, which not only realizes the full contact with air and the full combustion of materials, improves the incineration efficiency, but also is more energy-saving compared with the material pushing form of the existing incinerators and realizes low-energy consumption operation.

[0049] The power mechanism includes: an outer drum drive device 200 and an inner cutting shaft drive device 300.

[0050] The pusher component is composed of several waste material rollers 100. When the waste material rollers 100 rotate, they can push the waste materials on the material carrier plate 7. When multiple waste material rollers 100 rotate in the same direction together, the continuous movement of the waste materials can be realized, specifically along the longitudinal direction of the material carrier plate 7.

[0051] The waste pushing roller 100 includes: an outer drum 110, an inner cutting shaft 120, fixed pushing blades 130, and transverse pushing blades 140.

[0052] The outer drum 110 is driven by an outer drum driving device 200 so that it can rotate above the material carrier plate 7. Multiple groups of fixed pushing blades are arranged on the outer drum 110, and each group of fixed pushing blades is composed of a plurality of fixed pushing blades 130 arranged at equal intervals along the axial direction of the outer drum 110. In this embodiment, two groups of fixed pushing blades are taken as an example for illustration, and the number of fixed pushing blades 130 in each group can be determined according to the length of the waste pushing roller 100. When the outer drum 110 rotates, the fixed pushing blades 130 can push the waste.

[0053] In the prior art, to ensure the smooth rotation of the furnace roller, there is a certain gap between the fork on the furnace roller and the upper surface of the tray. As the fork rotates, when the waste just gets stuck in this gap, the furnace roller is very likely to get stuck. To solve this technical problem, those skilled in the art raise the height of the furnace roller to widen this gap to reduce the probability of jamming. However, the method of raising the height increases the thickness of the waste remaining on the tray. The large amount of waste residue not only affects the sufficiency of subsequent combustion but also is likely to generate flying dust when the combustion-supporting gas rushes in, thus affecting the incineration safety.

[0054] Therefore, in this embodiment, an inner cutting shaft 120 is arranged inside the outer drum 110, and the inner cutting shaft 120 can move along the axial direction of the outer drum 110. The movement of the inner cutting shaft 120 is driven by an inner cutting shaft driving device 300. Multiple groups of transverse pushing blades are arranged on the inner cutting shaft 120, and each group of transverse pushing blades is composed of a plurality of transverse pushing blades 140 arranged at equal intervals along the axial direction of the inner cutting shaft 120. In this embodiment, two groups of transverse pushing blades are taken as an example for illustration, and the number of transverse pushing blades 140 in each group can be determined according to the length of the waste pushing roller 100.

[0055] When the outer drum 110 rotates, the fixed pushing blades 130 and the transverse pushing blades 140 rotate together to realize continuous and uniform longitudinal pushing of the waste. At the same time, since the inner cutting shaft 120 can move along the axial direction of the outer drum 110, the transverse pushing blades 140 can also cut the waste transversely, that is, give a shearing force to the waste on the material carrier plate 7 to realize the transverse pushing of the waste. During the longitudinal movement of the waste, if a jamming situation occurs, the inner cutting shaft driving device 300 is started, and the transverse pushing blades 140 are driven by the inner cutting shaft 120 to realize the transverse pushing of the waste.

[0056] The structural design of the waste roller 100 ensures that the waste is pushed continuously and evenly longitudinally. The inscribed shaft 120 and the transverse pushing blade 140 provide a lateral force for the waste, so that the distribution of the waste changes, thereby helping to push out the waste stuck between the fixed blade 130 and the material carrier 7, and effectively solving the jamming problem of the waste roller 100. It can not only improve the operating stability and safety of the equipment, reduce the impact of the jamming problem on waste transportation and waste combustion, and ensure work continuity, but also appropriately reduce the height of the waste roller 100 to minimize the waste residues on the material carrier 7, avoiding the problem of large amounts of waste being retained.

[0057] In addition, the multi-directional movement of the waste allows the waste to more evenly and fully contact the flame ejected by the burner 6 and the combustion-supporting gas provided by the gas transmission channel during the incineration process, thereby further improving the completeness of the waste combustion and improving the combustion efficiency of the waste.

[0058] Each group of transverse push blades and each group of fixed blades are arranged alternately. The design of alternating arrangement allows the waste to be subjected to uniform force in both the longitudinal and transverse directions during the pushing process, so as to further reduce the possibility of the waste being stuck between the fixed blades 130 and the material carrier 7. Since the transverse push blades 140 can shear and push the stuck waste at any time, the problem of the machine being stuck during transportation can be effectively solved.

[0059] The wall of the outer drum 110 is provided with a rectangular hollow groove 111 between adjacent groups of fixed blades along the axial direction of the outer drum 110, and the transverse push blade 140 extends from the rectangular hollow groove 111. The rectangular hollow groove 111 provides a moving space for the transverse push blade 140 and plays a guiding role at the same time, so that the transverse push blade 140 can move smoothly laterally when pushing waste. Since the transverse push blade 140 extends from the rectangular hollow groove 111, the outer drum 110 can drive the inscribed shaft 120 to rotate together when rotating. This coordinated rotation mechanism simplifies the transmission structure, reduces the use of transmission parts, and reduces the complexity of the equipment and maintenance costs. Moreover, in order to reduce the friction between the transverse push blade 140 and the outer drum 110, a wear-resistant plate can be set on the groove wall of the rectangular hollow groove 111. The wear-resistant plate is made of a highly wear-resistant material, such as high-chromium cast iron, wear-resistant alloy steel, etc., and the surface of the wear-resistant plate is specially treated to improve the surface flatness and reduce friction.

[0060] In addition, compared with the existing structure design where the fork is a whole piece, the blades in each group of transverse pushing blades and each group of fixed blades in this embodiment are arranged discontinuously, that is, the blades in each group of transverse pushing blades and each group of fixed blades are not a continuous whole piece. In this embodiment, the distribution of the blades is further designed, that is, transverse pushing blades 140 are arranged on both sides of the gap 131 between two adjacent fixed blades in each group of fixed blades, so that the transverse pushing blades 140 and the fixed blades 130 are arranged alternately along the circumferential direction of the waste roller 100, forming a cross arrangement form of the blades.

[0061] The above-mentioned discontinuous arrangement form of the blades, combined with the cross arrangement form of the blades, forms a complementary pushing structure, which can not only ensure the smooth movement of the waste, but also prevent the waste from getting stuck, further effectively reducing the possibility of the waste getting stuck between the blades and the material carrier plate 7 during the pushing process, enabling the equipment to convey the waste at a higher efficiency, and thus improving the overall incineration treatment efficiency. At the same time, it helps to distribute the waste more evenly on the entire material carrier plate 7. The optimization of the waste distribution can reduce the energy consumption, so the operating cost can be reduced, and the energy efficiency ratio of the equipment can also be improved. In addition, the distribution form of the fixed blades 130 and the transverse pushing blades 140 in this embodiment enables the equipment to better adapt to different types, sizes and shapes of waste, enhancing the flexibility and wide applicability of the equipment.

[0062] The jamming adjustment module and the feedback adjustment module are the intelligent monitoring and adjustment units in the rolling shear type grate incineration equipment. Among them, the jamming adjustment module is used to collect the rotational torque of the outer drum 110, and when the rotational torque value reaches the adjustment threshold, it starts the inner cutting shaft driving device 300, so that the inner cutting shaft 120 moves reciprocally along the axial direction of the outer drum 110, and drives the transverse pushing blades 140 to perform the action of laterally scraping the waste.

[0063] The jamming adjustment module includes: a torque sensor, a data processor, and a driving board.

[0064] The torque sensor is installed on the outer drum 110 and is used to monitor the rotational torque of the outer drum 110 in real time. The data processor is used to receive and process the signals uploaded by the torque sensor, judge whether the rotational torque value reaches the preset adjustment threshold, and output corresponding control instructions. The driving board is connected to the inner cutting shaft driving device 300, and when it receives the start control instruction / stop control instruction issued by the data processor, it controls the inner cutting shaft driving device 300 to start / stop.

[0065] The data processor judges the received torque data according to a preset adjustment threshold. When the rotational torque value exceeds the threshold, it indicates that there may be a jamming phenomenon of the waste. The data processor immediately sends an instruction to the drive board. After receiving the start control instruction, the drive board starts the inner cutting shaft drive device 300, causing the inner cutting shaft 120 to reciprocate along the axial direction of the outer drum 110. As the inner cutting shaft 120 moves, the transverse pushing blade 140 performs the action of laterally scraping the waste, which can effectively change the distribution of the waste and relieve the jamming phenomenon. When the jamming phenomenon is relieved, the rotational torque of the outer drum 110 returns to the normal value. At this time, the data processor will send a shutdown control instruction to the drive board, and the inner cutting shaft drive device 300 stops working, and the device returns to the normal pushing state.

[0066] The jamming adjustment module monitors the rotational torque in real time, can detect, respond to and handle the waste jamming phenomenon in time, and automatically adjusts without manual intervention. It not only improves the operation stability and safety of the equipment, but also simplifies the operation process, ensuring the timeliness of dealing with the jamming phenomenon. At the same time, combined with the structural design of the waste roller 100, it realizes the rapid and effective treatment of the jamming phenomenon, avoids equipment overload and damage caused by frequent jamming, reduces the shutdown and maintenance time, extends the service life of the equipment, ensures the smooth movement of the waste, and improves the efficiency of waste incineration treatment. In summary, the jamming adjustment module realizes the rapid and effective treatment of the jamming phenomenon of the rolling shear type grate incineration equipment through real-time monitoring, intelligent judgment and automatic adjustment, ensuring the stable operation and high-efficiency treatment ability of the equipment.

[0067] The feedback adjustment module is used to collect the waste temperature before the start, during the operation and after the shutdown of the inner cutting shaft drive device 300, and issue a control instruction to the outer drum drive device 200 according to the difference in waste temperature change to adjust the rotation speed of the outer drum 110.

[0068] The feedback adjustment module includes: a temperature detection rod and a calculation and control unit.

[0069] The temperature detection rod is used to detect the temperature of the waste on the material carrier plate 7. Specifically, the temperature detection rod is installed near the material carrier plate 7 and can extend into the waste for real-time detection.

[0070] The calculation and control unit is used to obtain the waste temperature data uploaded by the temperature detection rod, calculate the target adjustment rotation speed V of the outer drum 110 according to the following formula, and send a control instruction to the outer drum drive device 200 to control the outer drum 110 to reach the target adjustment rotation speed V:

[0071]

[0072] V = max(0.9V0, min(1.1V0, V));

[0073] In the above formula, V0 is the reference speed of the outer drum 110, T1 is the average temperature of the waste material in a preset time period before the inscribed shaft driving device 300 is started, T2 is the average temperature of the waste material in a preset time period during the operation of the inscribed shaft driving device 300, and T3 is the average temperature of the waste material in a preset time period after the inscribed shaft driving device 300 is shut down. The preset time period can be set according to specific monitoring requirements. The calculation control unit considers the change of the waste material temperature over a period of time and calculates the average value, so that the temperature data is more referenceable, thereby realizing a more accurate speed adjustment in the future.

[0074] After the inscribed shaft driving device 300 is started, the waste will be moved with a larger amplitude and the distribution changes faster, which may easily increase the degree of combustion. In this case, the temperature change detected by the temperature detection rod is generally on the rise before and after the inscribed shaft driving device 300 is started. When the degree of combustion increases, it is very easy to cause local overheating. In this case, the rotation speed of the outer drum 110 needs to be increased to increase the waste conveying speed and avoid burning the equipment.

[0075] After the inscribed shaft driving device 300 is started, the swing of the transverse pushing blade 140 may easily lead to uneven distribution of waste, thereby causing incomplete combustion. In this case, the temperature change detected by the temperature detection rod generally shows a downward trend before and after the inscribed shaft driving device 300 is started. At this time, the rotation speed of the outer drum 110 needs to be reduced to extend the residence time of the waste and provide a longer incineration time for the waste.

[0076] Example 1:

[0077] When the combustion degree increases after the inscribed shaft driving device 300 is started, the calculation control unit obtains that T1 is 500°C, T2 is 600°C, and T3 is 700°C.

[0078] Target adjustment speed

[0079] According to V=max(0.9V0,min(1.1V0,V)), it is finally selected that the rotation speed of the outer drum 110 needs to be adjusted to 1.03V0, that is, the rotation speed of the outer drum 110 is increased.

[0080] Example 2:

[0081] When incomplete combustion occurs after the inscribed shaft driving device 300 is started, the calculation control unit obtains that T1 is 700°C, T2 is 600°C, and T3 is 500°C.

[0082] Target adjustment speed

[0083] According to V = max(0.9V0, min(1.1V0, V)), the rotational speed of the outer drum 110 finally selected needs to be adjusted to 0.97V0, that is, to reduce the rotational speed of the outer drum 110.

[0084] At the same time, use V = max(0.9V0, min(1.1V0, V)) to limit the upper and lower amplitudes of the rotational speed adjustment of the outer drum 110, that is, the maximum adjustment is to 1.1V0, and the minimum adjustment is to 0.9V0, so as to avoid the impact on the normal conveying of waste materials caused by excessive adjustment.

[0085] Through the feedback adjustment module, an association model between temperature and combustion state is established and a control strategy is output to achieve the dynamic balance of combustion efficiency and equipment safety. First, use T2 to capture the real-time state of combustion to avoid relying only on the lagging data of T3. Second, reduce the impact of single temperature fluctuations through weight distribution. Third, limit the upper and lower amplitudes of the rotational speed adjustment of the outer drum 110 to avoid affecting the normal conveying of waste materials due to excessive adjustment. Fourth, adjust in stages to reduce speed mutations. Therefore, the regulation data output in this embodiment is more in line with the actual situation, more referenceable, and realizes a higher matching rotational speed adjustment.

[0086] A smoke exhaust channel 24 is provided at the top of the furnace wall 2. The smoke exhaust channel 24 is connected to the secondary combustion chamber 3. The flue gas discharged from the combustion chamber 21 enters the secondary combustion chamber 3. The secondary combustion chamber 3 is used to further burn the combustible components in the flue gas to improve the combustion efficiency and reduce pollutant emissions. A burner and a high-temperature catalyst are provided in the secondary combustion chamber 3 to ensure the decomposition of harmful substances in the flue gas. A smoke exhaust outlet 31 is provided at the top of the secondary combustion chamber 3 for discharging the flue gas after secondary combustion.

[0087] The smoke exhaust outlet 31 is connected to the heat medium inlet of the heat exchanger 4, so that the high-temperature flue gas directly enters the heat exchanger 4 as a heat medium for heat exchange before being discharged. The air outlet of the blower 5 is connected to the refrigerant inlet of the heat exchanger 4, and the refrigerant outlet of the heat exchanger 4 is connected to the air delivery channel formed inside the furnace body skeleton 1. The blower 5 sends the combustion-supporting air into the heat exchanger 4 to perform heat exchange with the high-temperature flue gas discharged from the secondary combustion chamber 3 to realize the preheating of the combustion-supporting air. The combustion-supporting air after heat exchange enters the internal layer combustion incineration equipment through the air delivery channel.

[0088] The design of the secondary combustion chamber 3, the heat exchanger 4 and the blower 5 realizes the recovery and utilization of heat, preheats the combustion-supporting air entering the layer combustion incineration equipment, not only reduces the input demand for external energy, improves the energy utilization efficiency of the equipment, but also reduces the temperature gradient inside the layer combustion incineration equipment, reduces the thermal stress, and at the same time the heat exchanger 4 reduces the flue gas temperature, which helps to reduce the generation of nitrogen oxides.

[0089] There is a certain distance between the inner cylindrical wall of the outer drum 110 and the outer wall of the inner cutting shaft 120 to form a blowing cavity 150. The blowing cavity 150 is communicated with the air conveying channel. Due to the existence of the rectangular hollow groove 111, the rectangular hollow groove 111 is also communicated with the blowing cavity 150. At the same time, the ventilation beam 10 is welded to the furnace body framework 1 and the space inside the beam is also communicated with the air conveying channel. The stoker incineration equipment of this embodiment can provide combustion-supporting air for the interior of the equipment through the air outlet on the ventilation beam 10, and at the same time can also provide combustion-supporting air for the interior of the equipment through the rectangular hollow groove 111. Through the multi-point supply of combustion-supporting air, the waste can be in more sufficient contact with the combustion-supporting air and burn fully, improving the combustion efficiency of the waste. Moreover, the combustion-supporting air blows out from the rectangular hollow groove 111, which can effectively prevent sundries such as dust from entering the waste roller 100, reducing the wear and failure rate of the equipment.

[0090] In this embodiment, a set of pusher assemblies corresponds to one outer drum driving device 200. Specifically, the outer drum driving device 200 includes: a motor 210, a driving gear 220, a chain belt 230, and a driven gear 240.

[0091] The motor 210 is the power source for the rotation of the outer drum 110. The driving gear 220 is arranged on the power output shaft of the motor 210 to transmit the output power of the motor 210. The chain belt 230 is the transmission medium. The chain belt 230 is meshed with both the driving gear 220 and the driven gear 240, so as to transmit the rotation of the driving gear 220 to each driven gear 240, and then drive each outer drum 110 to rotate. Guide cylinder tubes 112 are arranged at both ends of the outer drum 110. The guide cylinder tubes 112 not only play a role in supporting the outer drum 110 to rotate, but also provide rotation guidance for it. Axial holes are opened on the furnace wall 2, and the guide cylinder tubes 112 pass through the axial holes, thereby realizing the positioning and rotation of the outer drum 110 in the furnace. The driven gear 240 is arranged on the guide cylinder tube 112.

[0092] The motor 210 is installed outside the furnace wall 2 and is connected to the driving gear 220 through the power output shaft. The driving gear 220 is meshed with the driven gear 240 through the chain belt 230 to form a complete transmission link. When the motor 210 starts, its power is transmitted to the chain belt 230 through the driving gear 220, and the chain belt 230 drives the driven gear 240 to rotate, thereby driving the outer drum 110 to rotate around its axis. The outer drum driving device 200 adopts gear and chain belt transmission, which has high transmission efficiency, good stability, can bear a large load, realizes the stable and efficient rotation of the outer drum 110, and provides a strong guarantee for the efficient and stable operation of the rolling shear type stoker incineration equipment.

[0093] The inner cutting shaft driving device 300 includes: a telescopic cylinder 310, a mounting bracket 320, and a cross-bearing bracket 330.

[0094] The telescopic cylinder 310 is the direct driving component of the inner cutting shaft 120. The telescopic cylinder 310 pushes or pulls the inner cutting shaft 120 through its telescopic action, enabling the inner cutting shaft 120 to reciprocate axially along the outer drum 110. The telescopic cylinder 310 is arranged on the mounting frame 320, and the mounting frame 320 is used for the installation and fixation of the telescopic cylinder 310. Since the mounting frame 320 is arranged on the guide column cylinder 112, both the mounting frame 320 and the telescopic cylinder 310 can rotate together with the outer drum 110, so that the rotation of the outer drum 110 does not affect the lateral movement of the inner cutting shaft 120.

[0095] Push-pull rods 121 are arranged at both ends of the inner cutting shaft 120. The push-pull rods 121 pass through the guide column cylinder 112 and are connected to the movable end of the telescopic cylinder 310. At the same time, the mounting frame 320 is arranged on the cross-bearing support 330. The cross-bearing support 330 is a support frame body, and multiple bearings are arranged thereon to support the rotation of the mounting frame 320. The design of the cross-bearing support 330 ensures the stability of the mounting frame 320 and the telescopic cylinder 310 during rotation. The design of the inner cutting shaft driving device 300 realizes the independent control of the rotation of the outer drum 110 and the lateral movement of the inner cutting shaft 120, reduces motion interference, improves the operation flexibility and adaptability of the equipment, that is, the position and moving speed of the inner cutting shaft 120 and the rotation speed of the outer drum 110 can be flexibly adjusted according to the incineration requirements.

[0096] Real-time feedback, precise adjustment:

[0097] The jamming adjustment module monitors the rotation torque of the outer drum 110 in real time, can detect and handle jamming phenomena in time, and the feedback adjustment module detects the waste temperature in real time through the temperature detection rod, providing precise data support for the rotation speed adjustment of the outer drum 110. The combination of the two realizes the real-time feedback and precise adjustment of the equipment operation state, improves the operation stability and incineration efficiency of the equipment, reduces equipment failures and downtime, and thus improves the reliability and service life of the equipment.

[0098] Cooperate to work, optimize combustion:

[0099] When the jamming adjustment module detects a jamming phenomenon and activates the inner cutting shaft driving device 300 for lateral scraping, the feedback adjustment module simultaneously monitors the change of the waste temperature and adjusts the rotation speed of the outer drum according to the change of the waste temperature, realizing two-way closed-loop control to optimize the combustion effect of the waste. This cooperative working method ensures the sufficiency and safety of the waste during combustion and guarantees the waste incineration efficiency;

[0100] Reduce jamming, reduce failures:

[0101] The structural design and position distribution of the waste dialing roller and the upper dialing blades thereon can not only ensure the smooth movement of the waste, but also effectively reduce the possibility of jamming of the waste during the pushing process, enabling the equipment to convey the waste with higher efficiency, improving the overall incineration treatment efficiency, and at the same time helping to distribute the waste more evenly on the entire material carrier plate 7. The optimization of the waste distribution can reduce the energy consumption, not only reducing the operating cost, but also improving the energy efficiency ratio of the equipment.

Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
