Abstract
Description
Technical Field
[0001] This utility model belongs to the field of waste recycling devices, specifically relating to a waste recycling device for kilns with recyclable energy. Background Technology
[0002] In the production of building materials, metal products, and ceramic products, kilns made of refractory materials are often used to fire the materials to be processed, completing the process from random mixing of minerals to the formation of chemical bonds and partial crystallization.
[0003] Currently, existing kilns generate a large amount of waste gas and fuel residue during the firing process. If these wastes are discharged directly without treatment, they will cause environmental pollution. Therefore, it is necessary to recycle and treat the waste gas and fuel residue.
[0004] Therefore, in response to the problem that existing kilns generate a large amount of waste gas and fuel residue during use and need to be recycled, a waste recycling device for kilns is designed to recycle and process the waste gas and fuel residue generated during the use of kilns. Utility Model Content
[0005] In order to overcome the problems of existing kilns in the process of firing products, such as the difficulty in purifying and treating the waste gas and the inconvenience of secondary recycling of fuel residue.
[0006] The technical solution of this utility model is as follows: a waste recycling device for a kiln with recyclable energy, including a kiln body, a combustion chamber, a waste gas recovery mechanism, a feeding component, a sliding component; the lower end of the kiln body is fixedly connected to a combustion chamber with built-in solid fuel placed on a support platform, the upper end of the kiln body is provided with a waste gas recovery mechanism, a feeding component for transferring fuel residue is installed in the combustion chamber, a waste gas recovery mechanism is provided on the left side of the combustion chamber, and a sliding component for adjusting the distance between the combustion recovery component and the combustion chamber is provided on the support platform.
[0007] Preferably, a waste gas recovery mechanism that can be connected to the kiln body is used to recover and treat the waste gas and fuel generated during the use of the kiln, remove harmful substances from the waste gas to prevent subsequent emissions from polluting the environment, filter the fuel and retain unburned fuel for the next use, and achieve energy recycling through a gas boiler through the waste heat generated during the use of the kiln. The feeding component transfers fuel residue from the combustion chamber to the waste gas recovery mechanism, and the sliding component is used to change the distance between the waste gas recovery mechanism and the combustion chamber.
[0008] Preferably, the waste gas recovery mechanism includes a flue, a cooling box, and a purification box. A flue with a filter structure is connected to the top of the kiln body. A double-layer cooling box is fixedly connected to the front of the flue. There is a cavity structure between the inner and outer layers of the cooling box, which is filled with flowing coolant. A purification box is fixedly connected to the front of the cooling box. The purification box is filled with activated carbon bags. The flue gas generated during kiln combustion is transferred to the cooling box through the flue. The filter structure inside the flue can block soot. The flowing cooling water carries away the heat in the flue gas through the cooling box. The purification box filters the cooled flue gas, and the activated carbon bags adsorb the impurities inside.
[0009] Preferably, a blower is connected to the front of the combustion chamber, and inlet and outlet water pipes are connected to the outside of the cooling box. The inlet water pipe is connected to a water tank, and the outlet water pipe is connected to a gas-fired boiler located at the front of the kiln body. The blower delivers fresh air to the combustion chamber, and the water tank pumps cold water into the cavity of the cooling box. The cooling water carries away the heat from the exhaust gas in the cooling box and connects the hot water to the gas-fired boiler through pipes. The gas-fired boiler delivers the hot water to other areas, uses the heat, and then returns the cold water to the water tank, thus realizing the recycling of energy.
[0010] Preferably, the feeding assembly includes a feeding gate, a feeding block, and a cylinder; the feeding gate is movably connected to the left side of the combustion chamber, the feeding block is provided inside the combustion chamber, and a cylinder with a piston rod connected to the feeding block is installed on the right side of the combustion chamber. After the cylinder is started, the piston rod pushes the feeding block to move from right to left, pushing the fuel residue in the combustion chamber out of the feeding gate position of the combustion chamber into the recovery box.
[0011] Preferably, the exhaust gas recovery mechanism includes a recovery box, a filter plate, and a pneumatic hammer. A recovery box is located on the left side of the discharge gate, and a filter plate with a filter screen structure is installed inside the recovery box. A pneumatic hammer is installed on the left side of the recovery box. After the pneumatic hammer is started, it strikes the recovery box, causing the fuel residue covered with dust on the top of the filter plate to vibrate, shaking off the dust on the outside. The dust passes through the filter screen and enters the lower area. The larger size of the incompletely burned fuel residue is left on the top of the filter screen.
[0012] As a preferred option, the waste gas recovery mechanism also includes a dust collection box and a dust suction head; a dust collection box with a built-in fan is set on the front side of the recovery box, and a dust suction head connected to the fan through an air duct is inserted into the bottom of the dust collection box. After the fan inside the dust collection box is started, the dust falling below the filter screen is sucked into the dust collection box through the dust suction head to collect the dust for subsequent processing.
[0013] Preferably, the sliding assembly includes a chute and a slider; the support platform has a chute, and the slider is slidably connected in the chute. An exhaust gas recovery mechanism is installed above the slider. The position of the exhaust gas recovery mechanism installed on the slider relative to the combustion chamber is changed by the movement of the slider in the chute, which facilitates the rapid advancement of the recovery box after the material gate is opened, and prevents dust leakage.
[0014] The beneficial effects of this utility model are:
[0015] 1. By setting up a waste gas recovery mechanism, the waste gas and fuel residue generated during the kiln firing process are recovered and treated. The waste gas is cooled and purified to remove harmful substances before being discharged, reducing environmental pollution. The fuel residue is filtered to collect the unburned fuel residue for the next use, preventing waste.
[0016] 2. The exhaust gas produced by the kiln combustion contains a large amount of residual heat. Heat is a valuable resource. By using a cooling box to transfer the heat in the exhaust gas to the cooling water, and then transporting the cooling water to the gas boiler, the energy can be recycled and the waste of heat energy can be reduced.

[0025] Please see Figure 1-2 This utility model provides an embodiment: an energy-recyclable kiln waste recycling device includes a kiln body 1, a combustion chamber 2, a waste gas recovery mechanism 3, a feeding assembly 4, a waste gas recovery mechanism 5, and a sliding assembly 6; the lower end of the kiln body 1 is fixedly connected to the combustion chamber 2, which contains solid fuel and is placed on a support platform 7; the upper end of the kiln body 1 is provided with the waste gas recovery mechanism 3; the feeding assembly 4 for transferring fuel residue is installed in the combustion chamber 2; the waste gas recovery mechanism 5 is provided on the left side of the combustion chamber 2; and the support platform 7 is provided with a mechanism to adjust the distance between the combustion recovery assembly and the combustion chamber 2.

The waste heat generated during the use of the kiln is recycled through the gas boiler 9. The feeding component 4 transfers fuel residue from the combustion chamber 2 to the waste gas recovery mechanism 5, and the sliding component 6 is used to change the distance between the waste gas recovery mechanism 5 and the combustion chamber 2.
[0026] Please see Figure 3-4 In this embodiment, the waste gas recovery mechanism 3 includes a flue 301, a cooling box 302, and a purification box 303. A flue 301 with a filter screen structure is connected to the top of the kiln body 1. A double-layer cooling box 302 is fixedly connected to the front of the flue 301. The cooling box 302 has a cavity structure between its inner and outer layers, filled with flowing coolant. A purification box 303 is fixedly connected to the front of the cooling box 302, and the purification box 303 is filled with activated carbon packets. A blower 8 is connected to the front of the combustion chamber 2. Inlet and outlet water pipes are connected to the outside of the cooling box 302. The inlet water pipe is connected to a water tank, and the outlet water pipe is connected to a gas-fired boiler 9 located at the front of the kiln body 1. The flue gas generated during kiln combustion is transferred to the cooling box 302 through flue 301. The filter structure inside flue 301 can block soot. The flowing cooling water carries away the heat from the flue gas through the cooling box 302. The purification box 303 filters the cooled flue gas, and activated carbon bags adsorb impurities. The water tank pumps cold water into the cavity of the cooling box 302. The cooling water carries away the heat from the exhaust gas in the cooling box 302 and connects the hot water to the gas boiler 9 through pipes. The gas boiler 9 delivers the hot water to other areas to use the heat and then returns the cold water to the water tank, realizing the recycling of energy.
[0027] Please see Figure 5-6In this embodiment, the feeding assembly 4 includes a feeding gate 401, a feeding block 402, and a cylinder 403; the feeding gate 401 is movably connected to the left side of the combustion chamber 2, and the feeding block 402 is disposed inside the combustion chamber 2; a cylinder 403 with a piston rod connected to the feeding block 402 is installed on the right side of the combustion chamber 2; the exhaust gas recovery mechanism 5 includes a recovery box 501, a filter plate 502, and a pneumatic hammer 503; the recovery box 501 is disposed to the left side of the feeding gate 401, and the recovery box 501 contains... A filter plate 502 with a filter screen structure is installed. A pneumatic hammer 503 is installed on the left side of the recycling bin 501. The waste gas recovery mechanism 5 also includes a dust collection bin 504 and a dust suction head 505. A dust collection bin 504 with a built-in fan is provided on the front side of the recycling bin 501. A dust suction head 505 connected to the fan through an air duct is inserted into the bottom of the dust collection bin 504. The sliding component 6 includes a slide groove 601 and a slider 602. The support platform 7 has a slide groove 601, and the slide groove 601 is slidably connected. There is a slider 602, and an exhaust gas recovery mechanism 5 is installed above the slider 602. After the cylinder 403 is started, the piston rod pushes the feeding block 402 to move from right to left, pushing the fuel residue in the combustion chamber 2 out of the feeding door 401 of the combustion chamber 2 into the recovery box 501. After the pneumatic hammer 503 is started, it strikes the recovery box 501, causing the fuel residue covered with dust on the filter plate 502 to vibrate, shaking off the dust on the outside. The dust passes through the filter screen and enters the lower area. The larger size of the incompletely burned fuel residue is left above the filter screen. After the fan inside the dust collection box 504 is started, the dust falling below the filter screen is sucked into the dust collection box 504 through the dust suction head 505 for collection, which is convenient for subsequent processing. The position of the exhaust gas recovery mechanism 5 installed on the slider 602 relative to the combustion chamber 2 is changed by the movement of the slider 602 in the slide 601, which makes it convenient to quickly push the recovery box 501 after the feeding door 401 is opened, preventing dust leakage.
[0028] During the operation, the workers first send the fuel into the combustion chamber 2 through the feeding door 401 for combustion. The blower 8 continuously sends fresh air into the combustion chamber 2 to prevent insufficient oxygen in the combustion chamber 2 from causing the fire to go out. After the temperature of the kiln is raised to a specific value, the items to be fired are put into the kiln and the firing begins.
[0029] The exhaust gas generated during firing is introduced into the cooling box 302 through the flue 301. Some of the soot is blocked by the filter structure inside the flue 301. The water tank uses a water pump to transport cold water into the cavity structure of the double-layer cooling box 302. The cold water carries away the heat from the flue gas in the inner layer and then enters the gas boiler 9 through the pipe. The gas boiler 9 transports the hot water out. After the heat in the hot water is used up, the cooled water is transported back to the water tank through the pipe, realizing the recycling of energy.
[0030] After firing, open the feeding door 401, and then quickly push the slider 602 and the fuel recovery assembly above the slider 602 into the slider 602, so that the recovery box 501 is close to the outer wall of the combustion chamber 2. Start the cylinder 403, and the cylinder 403 pushes the fuel residue in the combustion chamber 2 into the recovery box 501. Start the pneumatic hammer 503 to strike the recovery box 501, causing the filter plate 502 and the fuel residue above it to vibrate. The dust wrapped around the outside of the residue is shaken off. The unburned fuel residue, due to its larger volume, remains on the filter plate 502, waiting for the next use. After the fan in the dust collection box 504 is started, the dust suction head 505 sucks the dust below the recovery box 501 into the dust collection box 504, waiting for subsequent processing.
[0031] Through the above steps, waste gas recovery mechanisms 3 and 5 are set up to recover and treat the waste gas and fuel residue generated during the kiln firing process. The waste gas is cooled and purified to remove harmful substances before being discharged, reducing environmental pollution. The fuel residue is filtered, and unburned fuel residue is collected for future use to prevent waste. This solves the problems of existing kilns having difficulty in purifying waste gas and inconvenient secondary recycling of fuel residue during product firing.
[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
