Description

Technical Field

[0001] This utility model belongs to the field of sulfuric acid production technology, and more specifically, it relates to an environmentally friendly fluidized bed furnace for producing sulfuric acid. Background Technology

[0002] An environmentally friendly fluidized bed furnace is a device used in the sulfuric acid production process. It produces sulfur dioxide gas by burning sulfur or other sulfur-containing raw materials, which then reacts with oxygen in the air to generate sulfur trioxide, which is then converted into sulfuric acid. The environmentally friendly fluidized bed furnace is designed with special emphasis on reducing environmental pollution. It adopts efficient waste gas treatment technology to control sulfur dioxide (SO2) and other harmful substances in the emissions to meet environmental protection requirements.

[0003] After the environmentally friendly fluidized bed boiler is used and shut down, the smoke and dust raised and the slag produced during firing can easily fall into the pores of the gas distribution plate at the bottom of the boiler, causing blockage and affecting subsequent production. This requires manual cleaning by staff.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings to provide an environmentally friendly fluidized bed furnace for the production of sulfuric acid, in order to achieve a more practical purpose. Utility Model Content

The base has a first mounting groove inside. The furnace body is mounted on the top of the base and communicates with the first mounting groove. The gas distribution plate is mounted at the connection point between the furnace body and the first mounting groove. A first sliding groove is provided on one side of the first mounting groove. A first slider is slidably mounted within the first sliding groove. A rotating rod is rotatably mounted on one side of the first slider, and one side of the rotating rod extends into the first mounting groove. A mounting plate is mounted on the end of the rotating rod located within the first mounting groove. The mounting plate is located directly below the gas distribution plate. A plurality of unblocking cones are installed at the top of the mounting plate, and the positions and dimensions of the unblocking cones are respectively matched with the positions and dimensions of the air holes on the surface of the gas distribution plate. A first driving assembly is installed in the first sliding groove, and a second driving assembly is installed in the first sliding block.

[0023] Example:

[0024] As attached Figure 1 To be continued Figure 4 As shown:

[0025] This utility model provides an environmentally friendly fluidized bed furnace for sulfuric acid production, comprising a furnace body 1, a blower assembly 2, a gas distribution plate 3, and a base 4. The base 4 has a first mounting groove 5 inside. The furnace body 1 is mounted on the top of the base 4 and communicates with the first mounting groove 5. The gas distribution plate 3 is installed at the connection between the furnace body 1 and the first mounting groove 5. A first sliding groove 6 is provided on one side of the first mounting groove 5. A first slider 7 is slidably mounted in the first sliding groove 6. A rotating rod 8 is rotatably mounted on one side of the first slider 7, and one side of the rotating rod 8 extends into the first mounting groove 5. A mounting plate is mounted on the end of the rotating rod 8 located in the first mounting groove 5. 9. The mounting plate 9 is located directly below the gas distribution plate 3. Several unblocking cones 10 are installed on the top of the mounting plate 9. The position and size of the several unblocking cones 10 are matched with the position and size of the air holes on the surface of the gas distribution plate 3. The first drive assembly is installed in the first slide groove 6. The second drive assembly is installed in the first slider 7. The bottom end of the first mounting groove 5 is provided with a guide groove 11. The size of the guide groove 11 is matched with the size of the mounting plate 9. A recycling box 12 is inserted into one side of the base 4. The recycling box 12 extends into the first mounting groove 5 and is located below the guide groove 11. The blower assembly 2 is installed on one side of the base 4.

[0026] The first drive assembly includes a threaded rod 13, which is rotatably installed in the first slide groove 6 and passes through the upper and lower ends of the first slider 7 and is threadedly connected to the first slider 7. Through the rotation of the threaded rod 13, the first slider 7 moves under the limiting action of the first slide groove 6, which drives the mounting plate 9 and the unblocking cone 10 to move, so that the unblocking cone 10 can unblock the air holes on the surface of the gas distribution plate 3.

[0027] The base 4 has a first motor 14 installed on one side of its top end, and the output end of the first motor 14 is connected to the threaded rod 13 via a coupling. The first motor 14 drives the threaded rod 13 to rotate, thereby driving the first slider 7 to move.

[0028] The second drive assembly includes a second mounting groove 15, in which a worm gear 16 is rotatably mounted and connected to a rotating rod 8. A worm 17 is mounted at the bottom of the second mounting groove 15 and meshes with the worm gear 16. As the worm 17 rotates, the worm gear 16 rotates together with the worm gear 16 and drives the mounting plate 9 to rotate together through the rotating rod 8. This causes the slag impurities falling on the surface of the mounting plate 9 to fall into the recycling box 12 by gravity through the guide groove 11.

[0029] The first slider 7 has a second motor 18 installed on one side, and the output end of the second motor 18 is connected to the worm gear 17 through a coupling. The second motor 18 drives the worm gear 17 to rotate, which in turn drives the worm wheel 16 to rotate.

[0030] A controller 19 is installed on one side of the base 4. The controller 19 is electrically connected to the first motor 14 and the second motor 18, respectively, to facilitate the control of the overall circuit of the device.

[0031] The working principle of this embodiment is as follows: When using this environmentally friendly fluidized bed furnace for sulfuric acid production, the operator puts sulfur ore or other raw materials into the furnace body 1 for combustion and turns on the blower assembly 2 to use the furnace body 1 for sulfuric acid production. After a single production cycle is completed, the operator can turn on the first motor 14. The first motor 14 drives the threaded rod 13 to rotate. Under the limiting action of the first slide 6, the first slider 7 moves and drives the mounting plate 9 and the unblocking cone 10 to move, so that the unblocking cone 10 can unblock the pores on the surface of the gas distribution plate 3. The slag and debris falling along the pores first accumulate on the surface of the mounting plate 9. When the mounting plate 9 descends close to the first mounting plate 9, the debris accumulates on the surface of the mounting plate 9. When the slag is in the middle of the groove 5, the second motor 18 turns on and drives the worm gear 17 to rotate. Since the worm gear 17 is meshed with the worm wheel 16, the worm wheel 16 rotates together and drives the mounting plate 9 to rotate 180 degrees through the rotating rod 8. This causes the slag and impurities falling on the surface of the mounting plate 9 to fall into the recycling box 12 by gravity through the guide groove 11, making it convenient for workers to recycle. After recycling, the mounting plate 9 continues to rotate 180 degrees so that the unblocking cone 10 faces upward. At the same time, the first motor 14 continues to control the mounting plate 9 to descend, so that the bottom end of the mounting plate 9 is in close contact with the top end of the guide groove 11, thereby sealing the guide groove 11 and preventing the airflow from stirring up the collected slag and impurities.

[0032] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
