Abstract
Description
Technical Field
[0001] This utility model relates to the field of refractory brick production technology, and more specifically, to a refractory brick firing furnace. Background Technology
[0002] Refractory bricks, also known as fire bricks, are refractory materials made from refractory clay or other refractory raw materials. Refractory bricks are widely used in various high-temperature furnaces and thermal equipment in industries such as metallurgy, building materials, chemicals, and power. In actual production of refractory bricks, a firing furnace is required to complete the firing of the refractory brick blanks. In practice, they have the advantages of simple operation, stable structure, and good performance.
[0003] The prior art discloses a high-efficiency refractory brick firing furnace with application number CN202120735226.1. In this utility model, when a fan is used to dissipate heat inside the furnace body, there is no cleaning structure. Impurities in the air will clog the filter screen of the fan structure, thereby affecting the heat dissipation inside the furnace body. This poses a hidden danger to the continuous heat dissipation of this utility model. At the same time, when the screw structure is used to fasten the furnace door structure, the clamping parts that fit and sleeve on the side wall of the screw structure will be in close contact with the furnace door structure, making it inconvenient for operators to disassemble the screw clamping parts later, reducing the practicality of this utility model.
[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

An electric slide valve is installed at the upper end of the heat dissipation pipe, and an air guide duct is installed at the upper end of the electric slide valve. An installation cover is installed at the upper end of the air guide duct, and a fan is installed inside the installation cover. A furnace door is installed on the end face of the furnace body via hinges, and the side wall of the furnace door has two sets of clearance grooves. The end face of the furnace body is fixedly installed with… There are two sets of mounting screws, and the side walls of both sets of mounting screws are fitted with threaded hole plates. Multiple sets of resistance wires are embedded in the inner wall of the refractory brick masonry layer. Mounting tubes are mounted on both sides of the mounting cover via bearings, and two sets of connecting rods are installed between the two sets of mounting tubes. Filter screen covers are installed at the far ends of the two sets of mounting tubes. Two sets of high-speed electric push rods are fixedly inserted through the upper part of the mounting cover, and serrated plates are installed at the telescopic ends of the two sets of high-speed electric push rods. Gears are fixedly fitted on the side walls of the two sets of mounting tubes.
[0010] Furthermore, each of the two sets of threaded hole plates has two sets of annular grooves on its sidewalls, and pull ropes are wound and installed inside the four sets of annular grooves, with a frame plate installed at one end of each of the four sets of pull ropes.
[0011] Furthermore, the two sets of pull ropes on the same side are wound in opposite directions.

[0015] Furthermore, the lower part of the furnace body is equipped with four sets of self-locking casters.
[0016] (III) Beneficial Effects
[0017] Compared with the prior art, the present invention provides a refractory brick firing furnace, which has the following beneficial effects:
[0018] (1) This utility model adopts an installation cover, an installation pipe, and a filter screen cover. Before actually using the refractory brick firing furnace, through holes are first opened on the surface of the furnace body, the refractory brick masonry layer, and the installation cover to ensure that the high-temperature resistant wires connected to the multiple sets of resistance wires and the fan can be electrically connected to the control panel. The gap between the through holes and the high-temperature resistant wires is sealed with high-temperature resistant glue. Then, the firing rack for placing the refractory brick blanks can be placed in the refractory brick masonry layer. Then, the furnace door is used to seal the opening of the furnace body. Using the control panel, the multiple sets of resistance wires are made to work. At this time, the refractory brick blanks can be fired. After firing is completed, the furnace door is opened and closed. Then, the electric slide valve is opened and closed using the control panel. At the same time, the fan is made to work. External air can enter the installation through the two sets of filter screen covers and the two sets of installation pipes. Inside the hood, this portion of air enters the furnace body through the air guide duct and heat dissipation pipe, carrying away the hot air inside the furnace. Simultaneously, using the control panel and synchronous controller, two sets of high-speed electric push rods intermittently extend and retract, causing two sets of serrated plates to move intermittently up and down. Since the two sets of serrated plates mesh with two sets of gears, the synchronously moving serrated plates drive the two sets of gears to rotate. The two sets of gears, through two sets of mounting pipes, cause the two sets of filter screens to rotate. When the two sets of filter screens rotate, centrifugal force is used to shake off impurities adsorbed on the surface of the two sets of filter screens. Through the installation hood, mounting pipes, and filter screens, a cleaning structure is provided, which can clean the impurities adsorbed on the surface of the filter structure, ensuring continuous heat dissipation for the refractory brick firing furnace.
[0019] (2) This utility model uses mounting screws and threaded hole plates. As can be seen from the above operation, the furnace door needs to seal the opening of the furnace body. The operator needs to rotate the furnace door. When the furnace door is close to the furnace body, the two sets of mounting screws and two sets of threaded hole plates are engaged with each other. The operator puts the two sets of threaded hole plates clockwise onto the side walls of the two sets of mounting screws. Then the operator steps on the same side of the frame plate. This set of frame plates can be pulled by a pull rope on the same side to make the same side of the threaded hole plate continue to rotate clockwise. During this process, the threaded hole plate can retract the other pull rope on the same side. When this set of threaded hole plates is in close contact with the furnace door, the installation of the furnace door is completed. When the furnace door needs to be reset, the operator steps on another set of frame plates on the same side. This set of frame plates can be rotated counterclockwise by a set of pull ropes on the same side. At the same time, a set of pull ropes can be wound up. When this set of threaded hole plates is separated from the furnace door, it can be removed by rotating counterclockwise. The use of the other set of threaded hole plates is the same as the operation. It can be seen that by setting the installation screws and threaded hole plates, the furnace door structure can be fixed in a labor-saving and convenient way, which improves the practicality of the refractory brick firing furnace.

The control panel is electrically connected to the synchronization controller, the electric slide valve 5, the fan 8 and multiple sets of resistance wires via wires. The synchronization controller is electrically connected to two sets of high-speed electric push rods 16 via wires.

[0036] In one embodiment, four sets of self-locking casters are installed on the lower part of the furnace body 1.
[0037] Working principle:
[0038] Before actually using the refractory brick firing furnace, through holes are first made on the surfaces of the furnace body 1, the refractory brick lining layer 2, and the mounting cover 7 to ensure that the high-temperature resistant wires connected to the multiple sets of resistance wires and the blower 8 can be electrically connected to the control panel. The gap between the through holes and the high-temperature resistant wires is sealed with high-temperature resistant glue. Then, the firing rack for placing the refractory brick blanks can be placed inside the refractory brick lining layer 2. The opening of the furnace body 1 is then sealed with the furnace door 13. Using the control panel, the multiple sets of resistance wires are activated, and the refractory brick blanks can be fired. After firing, the furnace door 13 is opened and closed, and the electric slide valve 5 is opened and closed using the control panel. At the same time, the blower 8 is activated, and external air can pass through the two sets of filter screens 10 and the two sets of mounting pipes 9. Entering the interior of the mounting cover 7, this portion of air enters the furnace body 1 through the air guide duct 6 and heat dissipation pipe 4, carrying away the hot air inside the furnace body 1. Simultaneously, using the control panel and synchronous controller, the two sets of high-speed electric push rods 16 are intermittently extended and retracted, causing the two sets of serrated plates 17 to intermittently move up and down. Since the two sets of serrated plates 17 mesh with the two sets of gears 18, the synchronously moving serrated plates 17 drive the two sets of gears 18 to rotate. The two sets of gears 18, through the two sets of mounting pipes 9, cause the two sets of filter screens 10 to rotate. When the two sets of filter screens 10 rotate, centrifugal force is used to dislodge impurities adsorbed on the surface of the two sets of filter screens 10, which are then removed through the mounting cover 7, mounting pipes 9, and filter... The mesh cover 10 has a cleaning structure that can clean impurities adsorbed on the surface of the filter screen, ensuring continuous heat dissipation for the refractory brick firing furnace. Simultaneously, as described above, the furnace door 13 needs to seal the opening of the furnace body 1. The operator needs to rotate the furnace door 13. When the furnace door 13 is in contact with the furnace body 1, the two sets of mounting screws 11 and two sets of threaded hole plates 12 engage with each other. The operator then rotates the two sets of threaded hole plates 12 clockwise onto the side walls of the two sets of mounting screws 11. Afterwards, the operator steps on a set of frame plates 21 on the same side. This set of frame plates 21, through a set of pull ropes 20 on the same side, allows the set of threaded hole plates 12 on the same side to continue rotating clockwise. During this process, the threaded hole plates 12... 2. Another set of pull ropes 20 on the same side can be wound up. When this set of threaded hole plates 12 is in close contact with the furnace door 13, the installation of the furnace door 13 is completed. When the furnace door 13 needs to be reset, the operator steps on another set of frame plates 21 on the same side. This set of frame plates 21 can be rotated counterclockwise by a set of pull ropes 20 on the same side. At the same time, a set of pull ropes 20 can be wound up. When this set of threaded hole plates 12 is separated from the furnace door 13, it can be removed by rotating counterclockwise. The use of the other set of threaded hole plates 12 is the same as the operation. It can be seen that by setting the installation screws 11 and threaded hole plates 12, the furnace door structure can be fixed in a labor-saving and convenient way, which improves the practicality of the refractory brick firing furnace.
