Description

Technical Field

[0001] This utility model relates to the field of thermally modified kiln technology, specifically a thermally modified kiln for attapulgite preparation. Background Technology

[0002] Attapulgite is a hydrous magnesium aluminum silicate clay mineral with a chain-like layered structure. Its main components are silicon and magnesium. To improve its specific surface area and adsorption capacity, a thermal modification kiln is usually used to remove the water of crystallization and other impurities from attapulgite through high-temperature treatment. A thermal modification kiln is a device used to heat treat materials, mainly to change the microstructure and properties of the materials.

[0003] According to the patent publication number CN212457892U, a heat-modified kiln for preparing attapulgite is disclosed, "the kiln includes an operating hole on the top of the kiln, support legs are fixedly connected to the four corners of the bottom of the kiln, and the kiln is connected to a heat preservation mechanism."

[0004] However, when the above-mentioned device is used, the process of preparing attapulgite in the kiln is in a high-temperature environment, and the blower is close to the operating hole, which makes the blower easy to be damaged due to the high temperature. Therefore, in order to solve the above problems, a thermally modified kiln for preparing attapulgite is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a thermally modified kiln for attapulgite preparation, in order to solve the problem that the blower is easily damaged when extracting waste gas from the kiln due to the high temperature environment.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A thermally modified kiln for preparing attapulgite includes a kiln body, an operating hole, a heat insulation cover, and a heat insulation sleeve for preparing attapulgite. The operating hole is provided inside the kiln body. The heat insulation cover is attached to the top of the kiln body. The heat insulation sleeve is fixedly connected to the outside of the kiln body. Air inlet chambers are provided inside both the kiln body and the heat insulation sleeve. An electronic valve is provided at one end of each air inlet chamber. A fan is attached to the other end of each air inlet chamber. A support plate is attached to the bottom of the fan. The support plate and the heat insulation sleeve are fixedly connected. A heat dissipation assembly is provided on one side of each air inlet chamber. The heat dissipation assembly includes a heat-conducting rod, heat dissipation fins, and a fixing block. The heat-conducting rod is fixedly connected inside the kiln body. One end of the heat-conducting rod passes through the heat dissipation fins. The bottom of the heat dissipation fins is fixedly connected to the fixing block.

[0008] Preferably, the heat-conducting rod and the air inlet chamber are connected in a continuous manner, and the fixing block is fixedly connected to the top of the kiln body.

[0009] Preferably, a filter assembly is provided on one side of the fan and the heat-conducting rod, the filter assembly including a first dustproof net, a rubber sleeve, a second dustproof net and a rubber ball.

[0010] Preferably, a first dustproof net is tightly attached to one side of the fan, and the first dustproof net is bolted to the fan.

[0011] Preferably, a rubber sleeve is tightly fitted to the outside of the heat-conducting rod, and a second dustproof net consisting of a frame and a filter screen is fixedly connected inside the rubber sleeve.

[0012] Preferably, rubber balls are fixedly connected to both sides of the heat-conducting rod, and the rubber balls and the recesses of the rubber sleeve fit tightly together.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, the kiln body, operating hole, insulation cover, insulation sleeve, air inlet chamber, fan, support plate, and electronic valve are configured. The fan is positioned away from the operating hole and on the outside of the insulation sleeve. A heat dissipation assembly, heat-conducting rod, heat dissipation fins, and fixing block are used. The heat-conducting rod can conduct some of the heat from the air inlet chamber to the outside of the kiln body, and the heat dissipation fins can effectively dissipate heat from the heat-conducting rod. Together, they effectively cool the air inlet chamber, preventing the fan from being affected by high temperatures. A filter assembly, first dustproof net, rubber sleeve, second dustproof net, and rubber ball are also included. Since the exhaust gas contains a large amount of impurities, the first and second dustproof nets work together to effectively filter the exhaust gas emitted from the fan and heat-conducting rod, ensuring that impurities do not affect the air quality around the kiln body.

[0022] Please see Figure 1-4 This utility model provides a technical solution:

[0023] A heat-modified kiln for preparing attapulgite includes a kiln body 1 for preparing attapulgite, an operating hole 2, a heat insulation cover 3, and a heat insulation sleeve 4. The operating hole 2 is provided inside the kiln body 1. The heat insulation cover 3 is attached to the top of the kiln body 1. The heat insulation sleeve 4 is fixedly connected to the outside of the kiln body 1. Air inlet chambers 5 are provided inside both the kiln body 1 and the heat insulation sleeve 4. An electronic valve 10 is provided at one end of the air inlet chamber 5, and a fan 6 is attached to the other end of the air inlet chamber 5. A support plate 7 is attached to the bottom of the fan 6. The support plate 7 and the heat insulation sleeve 4 are fixedly connected. A heat dissipation assembly 8 is provided on one side of the air inlet chamber 5. The heat dissipation assembly 8 includes a heat-conducting rod 81, heat dissipation fins 82 and a fixing block 83. The heat-conducting rod 81 is fixedly connected inside the kiln body 1. One end of the heat-conducting rod 81 passes through the heat dissipation fins 82. The bottom of the heat dissipation fins 82 is fixedly connected to the fixing block 83. The heat dissipation assembly 8 prevents the fan 6 from being used in a high-temperature environment. The filter assembly 9 facilitates the effective filtration of impurities in the exhaust gas, so that the exhaust gas will not affect the air quality around the kiln body 1 after it is discharged.

[0024] The heat-conducting rod 81 and the air inlet chamber 5 are connected. The fixing block 83 is fixedly connected to the top of the kiln body 1, which facilitates the use of the heat-conducting rod 81 and the fixing of the heat dissipation fins 82. A filter assembly 9 is provided on one side of the fan 6 and the heat-conducting rod 81. The filter assembly 9 includes a first dustproof net 91, a rubber sleeve 92, a second dustproof net 93 and a rubber ball 94, which facilitates filtration on one side of the fan 6 and the top of the heat-conducting rod 81. The first dustproof net 91 is tightly attached to one side of the fan 6 and is bolted to the fan 6, which facilitates the use and disassembly of the first dustproof net 91. The rubber sleeve 92 is tightly attached to the outside of the heat-conducting rod 81. The second dustproof net 93, which is composed of a frame and a filter screen, is fixedly connected inside the rubber sleeve 92, which facilitates the use of the second dustproof net 93. Rubber balls 94 are fixedly connected to both sides of the heat-conducting rod 81. The rubber balls 94 and the recesses of the rubber sleeve 92 are tightly attached, which facilitates the disassembly of the second dustproof net 93.

[0025] Workflow: During operation, the equipment is powered by an external power source. When using the thermally modified kiln for attapulgite preparation, first place the kiln body 1 in a suitable position. For the specific usage of the kiln body 1, operating hole 2, insulation cover 3, and insulation sleeve 4, refer to the patent publication number CN212457892U for a thermally modified kiln for attapulgite preparation. Open the insulation cover 3 to feed attapulgite through the operating hole 2. Close the insulation cover 3 to put the kiln body 1 into operation. High-temperature treatment removes the crystal water and other impurities from the attapulgite. The kiln body 1 generates waste gas during operation. When waste gas treatment is required, the user opens the heat-resistant electronic valve 10 and starts the fan 6. The fan 6 draws the waste gas from the kiln body 1 to the outside through the air inlet chamber 5. The waste gas contains a large amount of heat and impurities. Since the air inlet chamber 5 and the heat-conducting rod 81 are connected, most of the heat is absorbed by the heat-conducting rod 81. The air flows from the inlet chamber 5 through the heat-conducting rod 81 and then outwards. The heat dissipation fins 82 effectively dissipate heat from the heat-conducting rod 81. The second dustproof net 93 at the top of the heat-conducting rod 81 effectively filters impurities from the heat. When the rubber sleeve 92 and the rubber ball 94 are used together, the installed second dustproof net 93 is simply fixed. The cooled exhaust gas is carried from the inlet chamber 5 to the outside of the kiln body 1 by the fan 6. The first dustproof net 91 on one side of the fan 6 effectively filters impurities in the exhaust gas. Since the first dustproof net 91 and the fan 6 are bolted together, the first dustproof net 91 can be disassembled and cleaned when it needs to be cleaned after long-term use. The prepared attapulgite can be discharged by opening the discharge structure at the bottom of the kiln body 1. The heat dissipation component 8 is set to prevent the fan 6 from being used in a high-temperature environment. The filter component 9 is set to facilitate the effective filtration of impurities in the exhaust gas, so that the exhaust gas will not affect the air quality around the kiln body 1 after discharge.
