Description

Technical Field

[0001] This utility model relates to the field of cement production technology, specifically to a multi-stage combustion pre-combustion furnace hazardous waste deep purification device. Background Technology

[0002] Cement production involves crushing, batching, grinding, and calcining raw materials such as limestone and clay at high temperatures, followed by grinding with admixtures to produce cement. Cement production is a complex process industry that integrates mineral processing, high-temperature metallurgy, and powder engineering. The new dry process achieves synergistic optimization of energy consumption, environmental protection, and efficiency through a technical system of "pre-homogenization - preheating decomposition - high-efficiency grinding." In the future, with the in-depth application of low-carbon technologies and intelligent technologies, the cement industry will transform towards "green manufacturing + circular economy," while facing the dual challenges of raw material resource constraints and carbon emission reduction.

[0003] In existing technologies, hazardous waste is generated during cement production. If this hazardous waste is not treated promptly, it will pollute the environment. Currently, hazardous waste is typically burned in a pre-combustion furnace. However, during combustion, the waste accumulates inside the furnace, making complete combustion and purification difficult, thus affecting the purification effect. Furthermore, some combustion processes produce harmful gases that cannot be effectively purified. Therefore, this application designs a multi-stage combustion pre-combustion furnace-based deep purification device for hazardous waste. Utility Model Content

[0006] This utility model provides a multi-stage combustion pre-combustion furnace hazardous waste deep purification device, including a chassis, a support frame, and a feeding box. The support frame is fixedly connected to the bottom of the chassis, and the feeding box is fixedly connected to the top side wall of the chassis. A stepped frame is fixedly connected to the inner wall of the bottom of the chassis. A motor is fixedly connected to the side wall of the chassis. A rotating shaft is rotatably connected inside the chassis. A material feeding frame is fixedly sleeved on the shaft wall of the rotating shaft. The output shaft of the motor is fixedly connected to the end of the rotating shaft. A groove is formed on the inner wall of the top of the stepped frame. A material feeding frame is fixedly connected to the side wall of the chassis. The controller includes a heater fixedly connected to the inner wall of the groove, a heat-conducting plate fixedly connected to the inner wall of the stepped frame at the top of the groove, a cylinder fixedly connected to the inner wall of the support frame, a connecting frame fixedly connected to the piston rod end of the cylinder, a transmission plate fixedly connected to the side wall of the connecting frame, multiple push-pull plates fixedly connected to the side wall of the transmission plate, the multiple push-pull plates extending into the interior of the stepped frame and fixedly connected to push plates, a notch opened in the inner wall of the stepped frame, the push plates slidingly disposed in the inner wall of the notch, and a discharge port opened in the bottom side wall of the casing.

[0007] Preferably, the upper surface of the stepped frame is set as an inclined surface.

[0008] Preferably, a baffle is fixedly connected to the top side wall of the push plate, and the baffle is slidably disposed on the top inner wall of the recess.

[0009] According to the multi-stage combustion pre-combustion furnace hazardous waste deep purification device as claimed in the claim, the device is characterized in that: a fixing frame is fixedly connected to the side wall of the casing, a filter box is fixedly connected to the top of the fixing frame, an air pump is fixedly connected to the top of the filter box, an air inlet pipe is fixedly connected to the top of the air pump, and the end of the air inlet pipe opposite to the air pump extends into the interior of the casing.

[0010] Preferably, a filter box is slidably disposed on the inner wall of the filter box, and a filter screen and an activated carbon adsorption screen are fixedly connected to the inner wall of the filter box.

[0011] Preferably, the top of the filter box is provided with an air inlet, and the bottom side wall of the filter box is fixedly connected with an air outlet pipe.

[0012] Preferably, the inner wall of the filter box has a notch, and the filter box is slidably provided with a cam located on the inner wall of the notch. The inner wall of the filter box has a slot, and the cam is clamped to the inner wall of the slot. A rotating handle is fixedly connected to the side wall of the cam, and the rotating handle extends through the notch to the outside of the filter box.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This multi-stage combustion pre-combustion furnace hazardous waste deep purification device uses a motor-driven rotating shaft to rotate the material feeding rack, which evenly distributes the hazardous waste onto the inclined surface of the stepped rack. The inclined design of the stepped rack allows the hazardous waste to gradually slide down under the action of gravity, prolonging the combustion time and ensuring a full reaction. At the same time, the material feeding rack disturbs the airflow inside the rack, which improves the uniformity of hazardous waste combustion.

[0015] 2. This multi-stage combustion pre-combustion furnace hazardous waste deep purification device, when the piston rod of the cylinder extends and retracts, drives the transmission plate to move horizontally through the connecting frame, causing the push plate to push the push plate to reciprocate within the recess of the stepped frame. The push plate pushes the hazardous waste from the upper layer to the lower layer, achieving stepped displacement. Afterward, the push plate resets, waiting for the next push. The pushing frequency can be adjusted by the controller to adapt to the combustion rate of different hazardous wastes. The baffle moves synchronously with the push plate to prevent hazardous waste from splashing upward during the pushing process, ensuring that the material slides down the slope in an orderly manner. The slope angle of the stepped frame is matched with the pushing frequency to meet the combustion time requirements of different hazardous wastes.

[0016] 3. This multi-stage combustion pre-combustion furnace hazardous waste deep purification device uses an air pump to draw combustion flue gas from the machine box through the air inlet pipe. The gas first passes through the filter box, where the filter screen intercepts particulate matter, and the activated carbon adsorption screen adsorbs volatile organic compounds and odors. Rotating the handle drives the cam to disengage from the slot, allowing the filter box to be pulled out to replace the filter screen and activated carbon adsorption screen. The locking design of the cam ensures that the filter box will not fall off under negative pressure. Attached Figure Description

[0021] A multi-stage combustion pre-combustion furnace hazardous waste deep purification device, such as Figure 1-3The device includes a chassis 1, a support frame 2, and a feeding box 3. The support frame 2 is fixedly connected to the bottom of the chassis 1, and the feeding box 3 is fixedly connected to the top side wall of the chassis 1. A stepped frame 4 is fixedly connected to the bottom inner wall of the chassis 1. A motor 5 is fixedly connected to the side wall of the chassis 1. A rotating shaft 6 is rotatably connected inside the chassis 1. A material feeding frame 7 is fixedly sleeved on the shaft wall of the rotating shaft 6. The output shaft of the motor 5 is fixedly connected to the end of the rotating shaft 6. A groove is formed on the top inner wall of the stepped frame 4. A controller 8 is fixedly connected to the side wall of the chassis 1, and a feeder is fixedly connected to the inner wall of the groove. Heater 9, stepped frame 4 is located at the top of the groove and the inner wall is fixedly connected to heat conduction plate 10, the inner wall of support frame 2 is fixedly connected to cylinder 11, the piston rod end of cylinder 11 is fixedly connected to connecting frame 12, the side wall of connecting frame 12 is fixedly connected to transmission plate 13, the side wall of transmission plate 13 is fixedly connected to multiple push-pull plates 14, the multiple push-pull plates 14 extend into the interior of stepped frame 4 and are fixedly connected to push plate 15, the inner wall of stepped frame 4 is provided with a notch, the push plate 15 is slidably disposed on the inner wall of the notch, and the bottom side wall of the casing 1 is provided with discharge port.

[0022] The upper surface of the step frame 4 is set as an inclined surface, and a baffle 16 is fixedly connected to the top side wall of the push plate 15. The baffle 16 is slidably set on the top inner wall of the recess.

[0023] A mounting bracket 17 is fixedly connected to the side wall of the chassis 1. A filter box 18 is fixedly connected to the top of the mounting bracket 17. An air pump 19 is fixedly connected to the top of the filter box 18. An air inlet pipe 20 is fixedly connected to the top of the air pump 19. The end of the air inlet pipe 20 away from the air pump 19 extends into the interior of the chassis 1. A filter box 21 is slidably arranged on the inner wall of the filter box 18. A filter screen 22 and an activated carbon adsorption screen 23 are fixedly connected to the inner wall of the filter box 21. An air inlet is opened at the top of the filter box 21. An air outlet pipe 24 is fixedly connected to the bottom side wall of the filter box 21.

[0024] In summary: Hazardous waste enters the machine housing 1 from the top feeding box 3. The hazardous waste is on the upper layer of the stepped rack 4 and is preheated to the ignition temperature by the heater 9. The controller 8 monitors the temperature of the heat conduction plate 10 in real time and adjusts the power of the heater 9. The heat conduction plate 10 allows for more complete heat conduction, during which the hazardous waste decomposes volatile organic compounds. While heating, the heater 9 also heats the entire stepped rack 4. The hazardous waste slides down to the middle and lower layers of the stepped rack 4. With the reciprocating push of the pusher plate 15, the hazardous waste is fully burned at high temperature, destroying organic pollutants. The motor 5 drives the rotating shaft 6 to rotate the material feeding rack 7, which evenly distributes the hazardous waste onto the inclined surface of the stepped rack 4. The inclined design of the stepped rack 4 allows the hazardous waste to gradually slide down under the action of gravity, extending the combustion time and ensuring a full reaction. At the same time, the material feeding rack 7 disturbs the airflow inside the machine housing 1, which improves the uniformity of hazardous waste combustion.

[0025] When the piston rod of cylinder 11 extends or retracts, it drives the transmission plate 13 to move horizontally through the connecting frame 12, causing the push plate 14 to push the push plate 15 to reciprocate within the recess of the stepped frame 4. The push plate 15 pushes the hazardous waste from the upper layer to the lower layer, achieving stepped displacement. Afterward, the push plate 15 resets and waits for the next push. The pushing frequency can be adjusted by the controller 8 to adapt to the combustion rate of different hazardous wastes. The baffle 16 moves synchronously with the push plate 15 to prevent the hazardous waste from splashing upward during the pushing process, ensuring that the material slides down the slope in an orderly manner. The slope angle of the stepped frame 4 is matched with the pushing frequency to meet the combustion time requirements of different hazardous wastes.

[0026] The air pump 19 draws combustion flue gas from the casing 1 through the air inlet pipe 20. The flue gas is first treated by the filter box 21, the filter screen 22 intercepts particulate matter, and the activated carbon adsorption screen 23 adsorbs volatile organic compounds and odors. The activated carbon iodine value is ≥800mg / g to ensure adsorption efficiency.

[0027] To replace filter 22 and activated carbon adsorption screen 23, such as Figure 1-3 As shown, the inner wall of the filter box 21 has a notch, and the filter box 21 is slidably provided with a cam 25 located on the inner wall of the notch. The inner wall of the filter box 18 has a slot, and the cam 25 is clamped on the inner wall of the slot. A rotating handle 26 is fixedly connected to the side wall of the cam 25, and the rotating handle 26 extends through the notch to the outside of the filter box 21.

[0028] Rotating the handle 26 causes the cam 25 to disengage from the slot, allowing the filter box 21 to be pulled out to replace the filter screen 22 and activated carbon adsorption screen 23. The locking design of the cam 25 ensures that the filter box 21 will not fall off under negative pressure.
