[0003] Among them, the hybrid heating box-type roasting kiln refers to a kiln that uses two or more heating methods simultaneously in the box-type kiln to roast materials, such as the combination of gas heating and electric heating, the combination of gas heating and other heating methods, etc., which has the advantages of improving heating efficiency, accurately controlling temperature, and being able to flexibly switch heating methods according to different working conditions.

[0004] However, the existing high-temperature new energy-saving hybrid heating box-type roasting kiln has the following deficiencies:

[0005] Most of the existing high-temperature new energy-saving hybrid heating box-type roasting kilns only have one door opening method, such as side-opening or top-opening.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. By setting up an auxiliary mechanism, the box-type roasting furnace of the present invention can have multiple door-opening methods. When there is a sudden equipment failure that requires emergency maintenance or an abnormal situation occurs inside the furnace that needs to be quickly handled, it is also possible to quickly select a suitable door-opening method according to the actual situation and quickly open the furnace door, thus avoiding the difficulty of opening the furnace, increasing the maintenance difficulty and time cost, and then improving the use efficiency of the box-type roasting furnace. When the box-type roasting furnace has a sudden failure that requires emergency maintenance or an abnormal situation occurs inside the furnace that needs to be quickly handled, and according to the on-site situation, it is necessary to open the side door of the furnace, at this time, directly loosen all the handwheels, and each single-headed screw can be rotated on the rotating shaft end of the corresponding second connecting member respectively and separated from the corresponding clamping block. Subsequently, by using the cooperation of all the first connecting members, all the clamping rods, all the rotating blocks and all the hollow blocks, the shell cover and the sealing gasket installed on the shell cover can be rotated until the shell cover is completely opened.

[0021] 2. When the box-type roasting furnace of the present invention has a sudden failure that requires emergency maintenance or an abnormal situation occurs inside the furnace that needs to be quickly handled, and according to the on-site situation, it is necessary to open the top door of the furnace, at this time, first use the cooperation of the control cabinet, two electric cylinders, two connectors, two groups of fixed pulleys, a group of diversion holes, all the stabilizing frames, the U-shaped frame and all the reinforcing plates to make one end of all the steel wire ropes move simultaneously. Subsequently, by using the cooperation of one end of all the moving steel wire ropes, the auxiliary holes, the screw rods, all the auxiliary members and the nuts, the shell cover, all the clamping blocks, all the hollow blocks and the sealing gasket connected to the shell cover can be stably lifted upward simultaneously. Then, remove all the clamping rods, and each rotating block can be rotated inside the corresponding first connecting member respectively to ensure that the shell cover can rise normally until the shell cover is completely opened.

[0022] 3. By setting up a furnace mechanism, the present invention can realize the roasting operation of materials. When the materials need to be roasted, first open the shell cover, place the material rack with the materials to be roasted into the refractory layer, and then close it. Subsequently, by using the cooperation of the control cabinet, all the burners, all the first electric regulating valves, all the second electric regulating valves, all the connecting pipes and all the filter plates, the fuel transported by the two shunt pipes and the air filtered from the environment and then sucked in can be mixed first, then ignited, and then sprayed out in the refractory layer to heat the air inside the refractory layer. Then, by using the cooperation of the control cabinet and the resistance wires, the air inside the refractory layer can be heated, and double mixing heating can be realized, generating high temperature to uniformly roast the materials at high temperature.

[0023] 4. The present invention simultaneously utilizes the cooperation of the refractory layer, the heat insulation layer and the gasket to prevent heat loss, avoid the energy consumption required to maintain the furnace temperature, that is, achieve the purpose of energy saving. At the same time, by using the cooperation of the control cabinet and the temperature sensor, overheating inside the refractory layer can be achieved, that is, the purpose of energy saving is achieved. Then, by using the cooperation of the connecting pipe, the exhaust gas generated during fuel combustion can be discharged. When the material does not need to be roasted, heating is stopped. When the temperature inside the box-type roasting furnace naturally drops, the shell cover is opened, and the roasted material can be taken out. BRIEF DESCRIPTION OF THE DRAWINGS

The intake end of the exhaust pipe 108 sequentially passes through the outer wall of the insulating layer 103 and the outer wall of the refractory layer 104 and is connected to the interior of the refractory layer 104. A control cabinet 109 is additionally installed on the outer wall of the housing 102. A U-shaped frame 110 is provided around the outer wall of the housing 102. Two groups of reinforcing rods 111 are fixed on the surface of the U-shaped frame 110, and both groups of reinforcing rods 111 are installed on the frame base 101. A plurality of U-shaped ceramic rods 112 are additionally installed on the inner wall of the refractory layer 104. A resistance wire 113 is provided between the outer surfaces of the plurality of U-shaped ceramic rods 112. Both ends of the resistance wire 113 are fixed with insulating tubes 114. The opposite ends of the two insulating tubes 114 sequentially pass through both sides of the inner wall of the refractory layer 104, both sides of the inner wall of the insulating layer 103, and both sides of the inner wall of the housing 102. A group of perforated plates 115 are fixed at both sides of the frame base 101 near the top position. A burner 116 is additionally installed on the surface of each perforated plate 115. The flame ejection nozzle of each burner 116 is movably sleeved inside the through hole of each perforated plate 115. The flame ejection nozzle of each burner 116 sequentially passes through the outer wall of the housing 102, the outer wall of the insulating layer 103, and the outer wall of the refractory layer 104 and extends into the interior of the refractory layer 104. The fuel intake end of each burner 116 is connected to a connecting pipe 117. The fuel intake end of each connecting pipe 117 is connected to a first electric regulating valve 118. The air intake end of each burner 116 is connected to a second electric regulating valve 119. The plurality of first electric regulating valves 118 are divided into two groups. A shunt pipe 120 is connected between the fuel intake ends of each group of the above-mentioned first electric regulating valves 118. A filter plate 121 is additionally installed at the air intake port of each second electric regulating valve 119.

[0043] In this embodiment, when the material needs to be calcined, first open the shell cover 105, then sequentially place the high-temperature resistant rack with the material into the refractory layer 104, then close and fix the shell cover 105. Subsequently, use the connected fuel delivery equipment to deliver fuel into the two shunt pipes 120 respectively. Then, use the control cabinet 109 to open all the first electric control valves 118 and all the second electric control valves 119, and adjust the valve opening degrees of each first electric control valve 118 and each second electric control valve 119. After that, use the control cabinet 109 to start all the burners 116 simultaneously.

At the same time, the control cabinet 109 will also start the resistance wire 113. At this time, the started resistance wire 113 will also heat the air inside the refractory layer 104. That is, use the heated high-temperature air to perform the calcination operation on the material. At the same time, with the cooperation of the refractory layer 104, the heat insulation layer 103, and the gasket 106, heat loss can be prevented, thereby avoiding the energy consumption required to maintain the furnace temperature, that is, achieving the energy-saving effect. At the same time, the control cabinet 109 will also, in cooperation with the temperature sensor 107, automatically adjust the fuel supply amount, ventilation amount, etc. of the burner 116 in real time, so that the kiln furnace is always in the best operating state. At the same time, when the temperature reaches the temperature threshold set by the control cabinet 109 in advance, the control cabinet 109 will reduce the heating power of the burner 116 and the heating power of the resistance wire 113 to prevent overheating, thereby achieving energy saving. At the same time, the waste gas generated by fuel combustion will enter the exhaust pipe 108 and then be transported to the waste gas treatment equipment for treatment. When the material does not need to be calcined, at this time, close all the burners 116, all the first electric control valves 118, all the second electric control valves 119, and the resistance wire 113, and at the same time stop the fuel supply to the shunt pipe 120. Then, wait for the temperature inside the box-type calcination kiln furnace to drop naturally, and then open the shell cover 105 to take out the calcined material.

When the shell cover 105 cannot move anymore, at this time, the control cabinet 109 will pause the two electric cylinders 208 simultaneously to keep the moved shell cover 105 in a fixed state. Then, the staff can perform maintenance or other processing operations on the box-type roasting furnace.

[0046] The effects and working principles achieved by the entire mechanism are as follows:

[0047] In the preparation stage, first connect the control cabinet 109, temperature sensor 107, heating wire 113, all burners 116, all first electric control valves 118, all second electric control valves 119 and all electric cylinders 208 in accordance with electrical safety codes, relevant standards and specifications. Subsequently, connect the control cabinet 109 to the power grid. Then, turn on the control cabinet 109 and set parameters such as the temperature threshold, heating rate, heating power, etc. After that, connect the gas outlet end of the exhaust pipe 108 to the gas inlet end of the prepared waste gas treatment equipment. Then, connect the feeding ends of the two shunt pipes 120 to the discharging end of the prepared fuel delivery equipment;

[0048] In the side door opening stage, when the box-type roasting furnace suddenly breaks down and needs emergency repair or there are abnormal conditions in the furnace that need to be quickly handled, and according to the on-site situation, it is necessary to open the side door of the furnace. At this time, first remove the screws and nuts of the fixed auxiliary part 217 and the shell cover 105. Subsequently, use the control cabinet 109 to simultaneously start the two electric cylinders 208. At this time, each started electric cylinder 208 will drive one end of the corresponding steel wire rope 207 to move under the cooperation of the connecting head 210, corresponding diversion hole 205 and corresponding set of fixed pulleys 206 connected to it. Then, each moving steel wire rope 207 will drive the connected auxiliary part 217 to move. When the telescopic end of the electric cylinder 208 completely retracts into its own interior, at this time, the control cabinet 109 will simultaneously pause the two electric cylinders 208. Subsequently, loosen all the handwheels 221. Then, use each handwheel 221 to drive the connected single-headed screw 219 to rotate respectively. After that, use all the first connecting parts 212, all the clamping rods 213, all the rotating blocks 214 and all the hollow blocks 215 to cooperate to make the shell cover 105 rotate. At the same time, the rotating shell cover 105 will also drive the connected sealing gasket 106 to move. When the shell cover 105 is completely opened, at this time, the staff can repair the box-type roasting furnace or perform other processing operations;

[0049] During the upper door opening stage, when the box-type roasting furnace suddenly fails and requires emergency maintenance, or when abnormal conditions occur inside the furnace and need to be quickly handled, and it is necessary to open the upper door of the furnace according to the on-site situation, first repeat the above operation steps at this time. Rotate and move all the single-headed screws 219 from the corresponding clamping blocks 220 respectively. Then, use the control cabinet 109 to simultaneously start the two electric cylinders 208. The two started electric cylinders 208 will drive one end of all the steel wire ropes 207 to move simultaneously under the cooperation of the two connectors 210, two groups of fixed pulleys 206, one group of diversion holes 205, all the stabilizing frames 202, the U-shaped frame 110, and all the reinforcing plates 204. Then, one end of all the simultaneously moving steel wire ropes 207 will drive the shell cover 105, all the clamping blocks 220, all the hollow blocks 215, and the gasket 106 connected to the shell cover 105 to move upward stably simultaneously under the cooperation of the auxiliary holes 216, the screw rods, all the auxiliary parts 217, and the nuts. When each hollow block 215 is separated from the rotating shaft end of the corresponding rotating block 214 respectively, first pause the movement of the shell cover 105 at this time. Then, remove each clamping rod 213 from the corresponding first connecting part 212 respectively. Then, rotate each rotating block 214 until it cannot be rotated. Then, continue to move the shell cover 105. When the shell cover 105 cannot move anymore, the control cabinet 109 will simultaneously pause the two electric cylinders 208 at this time to keep the moved shell cover 105 in a fixed state. Then, the staff can perform maintenance or other processing operations on the box-type roasting furnace;

[0050] Roasting stage: When the material needs to be roasted, open the shell cover 105 according to the operation steps of the above top-opening stage or side-opening stage. Then, put the high-temperature resistant racks with the materials into the interior of the refractory layer 104 in sequence. Next, close and fix the shell cover 105. Subsequently, use the connected fuel delivery equipment to deliver fuel into the interiors of the two shunt pipes 120 respectively. Then, use the control cabinet 109 to open all the first electric control valves 118 and all the second electric control valves 119, and adjust the valve opening degrees of each first electric control valve 118 and each second electric control valve 119. After that, use the control cabinet 109 to start all the burners 116 simultaneously. At this time, each started burner 116 will mix the delivered fuel and the air that is first filtered from the environment and then sucked in, ignite it, and then spray it out in the refractory layer 104 to heat the air inside the refractory layer 104. At the same time, the control cabinet 109 will also start the resistance wire 113. At this time, the started resistance wire 113 will also heat the air inside the refractory layer 104. That is, use the heated high-temperature air to roast the material. At the same time, with the cooperation of the refractory layer 104, the heat insulation layer 103 and the gasket 106, heat loss can be prevented, thus avoiding the energy consumption required to maintain the furnace temperature, that is, achieving an energy-saving effect. At the same time, the control cabinet 109 will also, in cooperation with the temperature sensor 107, automatically adjust the fuel supply amount, ventilation volume, etc. of the burner 116 in real time, so that the kiln furnace is always in the best operating state. At the same time, when the temperature reaches the temperature threshold set by the control cabinet 109 in advance, the control cabinet 109 will reduce the heating power of the burner 116 and the heating power of the resistance wire 113 to prevent overheating, thus achieving energy saving. At the same time, the waste gas generated by fuel combustion will enter the interior of the exhaust pipe 108 and then be transported to the waste gas treatment equipment for treatment. When the material does not need to be roasted, at this time, turn off all the burners 116, all the first electric control valves 118, all the second electric control valves 119 and the resistance wire 113, and at the same time stop the fuel supply to the shunt pipe 120. Then, wait for the temperature inside the box-type roasting kiln furnace to drop naturally. Next, open the shell cover 105 and take out the roasted material.

[0051] Among them, the heat insulation layer 103 is composed of ceramic fiber boards and is fixed on the shell 102 by anchor bolts or steel strips. The refractory layer 104 is composed of refractory bricks, and the refractory bricks and the ceramic fiber board brackets are fixed together by castable.

[0052] Among them, the heat insulation layer 103, the refractory layer 104, the temperature sensor 107, the control cabinet 109, the burner 116, the first electric control valve 118, the second electric control valve 119 and the electric cylinder 208 are all prior arts, and their models can be selected according to the actual situation and will not be explained in detail here.

[0053] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
