Description

Technical Field

[0001] This utility model belongs to the field of antique brick technology, and in particular relates to a self-cleaning, pressure-resistant, protective, and anti-aging antique brick calcining kiln. Background Technology

[0002] Self-cleaning, pressure-resistant, protective, and anti-aging antique-style bricks are a new type of building material combining multiple functional characteristics. Through nano-level hydrophobic / hydrophilic coatings or photocatalytic technologies such as titanium dioxide, the brick surface possesses stain-resistant and self-cleaning capabilities; using high-strength ceramic bodies or composite materials such as fiber reinforcement, the compressive strength can reach over 80MPa, far exceeding the typical 30-50MPa of ordinary ceramic tiles; the addition of UV-resistant additives or the use of special glazes can resist fading and chalking caused by long-term UV exposure; and through weather resistance tests such as the QUV accelerated aging test, it ensures no significant performance degradation even after more than 20 years of outdoor use.

[0003] In the prior art, the calcining kiln is one of the main pieces of equipment in the processing of antique bricks. According to the search, the patent with publication number CN217636823U discloses a new type of kiln for the production of antique bricks. This equipment can filter the exhaust gas and utilize the waste heat of the gas. However, in actual use, the filter screen and activated carbon box are fixedly installed, which is inconvenient to disassemble and install, and is not conducive to later replacement and maintenance. Moreover, the flue gas exchanges heat with the water tank only after multiple filtrations. The preceding structure has already absorbed a lot of heat, resulting in low heat of the flue gas when it comes into contact with the water tank.

[0004] Therefore, we propose a self-cleaning, pressure-resistant, protective, and anti-aging antique brick firing kiln. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of the existing technology, such as the fixed installation of filter screen and activated carbon box, which is inconvenient to disassemble and install, and is not conducive to later replacement and maintenance. In addition, the flue gas only exchanges heat with the water tank after multiple filtrations, and the preceding structure has absorbed a lot of heat, resulting in low heat of flue gas when in contact with the water tank. Therefore, a self-cleaning, pressure-resistant, protective, anti-aging antique brick calcining kiln is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A self-cleaning, pressure-resistant, protective, and anti-aging antique brick firing kiln, comprising:

[0008] The kiln body has an exhaust pipe fixedly connected to its gas outlet end.

[0009] A filter box is fixedly installed on one side of the kiln body. A door with a lock is hinged to one side of the filter box. A water tank is fixed at the top of the filter box. The exhaust pipe passes through the water tank and communicates with the inner cavity of the filter box.

[0010] Two pairs of guide plates are symmetrically fixed to the inner walls of both sides of the filter box. The filter box and the activated carbon box are slidably connected between the two pairs of guide plates. The filter box is located above the activated carbon box.

[0011] The fan is fixed to the outer wall of one side of the filter box. The fan inlet is connected to the inner cavity of the filter box and is located below the activated carbon box. The fan outlet is connected to the exhaust pipe.

[0012] The flue gas enters the water tank for heat exchange through the exhaust pipe, then enters the filter box, passes through the filter box and activated carbon box in sequence, and is discharged by the fan.

[0013] In one possible design, a fixed frame is fixed inside the filter box, and multiple fixed rods are fixed on the surface of the fixed frame. The fixed rods are slidably sleeved onto the upper filter plate and the lower filter plate.

[0014] In one possible design, handles are fixed to the surfaces of the upper and lower filter plates, and push-pull blocks are fixed to the bottom of the filter box and activated carbon box.

[0015] In one possible design, the top of the water tank is fixedly connected to an inlet pipe, and one side of the water tank is fixedly connected to an outlet pipe with a control valve.

[0016] In one possible design, the outer wall of the exhaust pipe is fitted with an insulation sleeve, which covers the section from the kiln body to the water tank inlet.

[0017] In one possible design, a support sleeve is slidably fitted onto the outer wall of the fixed rod, and the support sleeve is located between the upper filter plate and the lower filter plate.

[0018] In this application, during use, the flue gas undergoes heat exchange through the exhaust pipe and water tank. The gas after heat exchange continues to carry dust into the filter box. After double filtration by the upper and lower filter plates, and then adsorption filtration by the activated carbon box, the gas is extracted and discharged by the fan.

[0019] During maintenance, open the chamber door, use the push-pull block to pull out the filter box and activated carbon box, use the handle to remove the upper filter plate and lower filter plate for cleaning and maintenance, and maintain the filter box and activated carbon box at the same time. After maintenance, put the filter box and activated carbon box back into the filter chamber, and finally close the chamber door.

[0020] Beneficial effects: In this utility model, the self-cleaning, pressure-resistant, protective, anti-aging antique brick calcining kiln, through the setting of the upper filter plate, lower filter plate and activated carbon box and other structures, can facilitate the quick disassembly of the filter box and activated carbon box, providing convenience for later maintenance;

[0021] In this utility model, the self-cleaning, pressure-resistant, protective, anti-aging antique brick calcining kiln, through the setting of exhaust pipe and water tank, allows the exhaust flue gas to exchange heat with the water tank first, reducing heat loss;

[0022] This invention allows for quick and easy disassembly of the filter box and activated carbon box, facilitating later maintenance. It also allows the exhaust gas to exchange heat with the water tank first, reducing heat loss. Attached Figure Description
