Description

Technical Field

[0001] This utility model relates to the field of ceramic firing equipment technology, specifically an energy-saving shuttle kiln for Jun porcelain. Background Technology

[0002] The Jun porcelain shuttle kiln is an intermittent flame-heated kiln, mainly used for firing Jun porcelain, and widely used in various industrial production processes.

[0003] The prior art, disclosed in patent publication number CN221325124U, presents the following technical solution: A novel energy-saving shuttle kiln for Jun porcelain, comprising a shuttle kiln body and a kiln car, the kiln car being sized to fit the shuttle kiln body. A PLC controller is installed on the rear side of one side of the shuttle kiln body. The kiln also includes a transmission cavity, which is located on the front side of the upper end of the shuttle kiln body. A first rotating shaft is rotatably mounted inside the transmission cavity, and second rotating shafts are located on both sides of the lower end of the transmission cavity. One end of each of the second rotating shafts extends through and out of the transmission cavity. This novel energy-saving shuttle kiln for Jun porcelain can avoid the rapid heat loss caused by large gaps when the kiln car is pulled out.

[0004] The flue gas from the above-mentioned technical solution can be heated at the front end of the kiln by passing through the insulation material. However, the residual heat is directly discharged after heating, which not only wastes some of the residual heat but also exacerbates the greenhouse effect. Utility Model Content

[0005] The purpose of this utility model is to provide an energy-saving shuttle kiln for Jun porcelain to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving Jun porcelain shuttle kiln, comprising a shuttle kiln body, a flue gas dust removal device installed at the upper end of the shuttle kiln body, a waste heat recovery device installed at the outlet of the flue gas dust removal device, and the waste heat recovery device installed on the outer wall of one side of the shuttle kiln body.

[0007] The waste heat recovery device includes a waste heat recovery box, which is located at the rear end of the outer wall of one side of the shuttle kiln body.

A cold air inlet is provided at the front end of the waste heat recovery box, and an air inlet pipe is provided on the other side of the waste heat recovery box. The waste heat recovery box is connected to the air inlet of the shuttle kiln body through the air inlet pipe. A water tank is provided at the front end of the outer wall of one side of the shuttle kiln body. A serpentine tube is installed inside the water tank. One end of the serpentine tube passes through the water tank and is connected to the outlet of the spiral metal tube. The other end of the serpentine tube passes through the water tank. A water inlet pipe is provided at the upper end of the water tank, and a drain pipe is provided at the bottom side of the water tank. A valve is provided on the drain pipe.

[0008] In the above technical solution, a spiral metal tube is installed in the waste heat recovery box. When the flue gas after dust removal passes through the spiral metal tube, it can exchange heat with the fresh air in the opposite direction, which increases the temperature of the combustion air and reduces the fuel consumption in the combustion chamber. In addition, the spiral metal tube is connected to the serpentine tube. After the flue gas heat is initially recovered through the spiral metal tube, the remaining heat is used to heat the water tank through the serpentine tube, thereby improving the recovery efficiency.

[0009] As a further preferred embodiment of this technical solution, the inner wall of the waste heat recovery box is provided with a ceramic fiber insulation layer.

[0010] The above technical solution improves the insulation effect of the waste heat recovery box and reduces heat dissipation.

[0011] As a further preferred embodiment of this technical solution, the flue gas dust removal device includes a housing. Both ends of the bottom side of the housing are provided with slots. The front and rear side walls of both ends of the housing are provided with T-shaped grooves. T-shaped plates are slidably connected in each T-shaped groove. A filter screen is provided between the two front and rear T-shaped plates at one end, and an activated carbon plate is provided between the two front and rear T-shaped plates at the other end. The T-shaped plates and the activated carbon plates are correspondingly engaged in the slots.

[0012] In the above technical solution, the filter screen can intercept large dust particles in the flue gas, reducing the load on subsequent treatment, while the activated carbon plate adsorbs fine particles, pollutants, and odors, achieving synergistic purification of dust and harmful gases.

[0013] As a further preferred embodiment of this technical solution, a top plate is fixedly connected to the top side of both the T-shaped plate and the activated carbon plate, and mounting plates are fixedly connected to the outer walls of both the front and rear sides of the top plate.

[0014] As a further preferred embodiment of this technical solution, the top side of the box is provided with a box cover by rivets, and both ends of the box cover are provided with T-shaped grooves. The outer wall of the T-shaped plate and the activated carbon plate are slidably connected to the inner wall of the T-shaped grooves. The upper end of the T-shaped grooves is provided with fitting grooves.

[0015] As a further preferred embodiment of this technical solution, the top plates are all fitted into the fitting grooves, and the mounting plates are connected to the box cover by rivets.

[0016] In the above technical solution, the filter screen and activated carbon plate are attached to the box body by T-shaped plates and connected to the box cover by top plate, mounting plate and rivets, which facilitates disassembly and replacement.

[0017] As a further preferred embodiment of this technical solution, a blower is provided on one side of the box body near the upper end of the shuttle kiln body, and an exhaust pipe is provided at the air inlet end of the blower. The exhaust pipe is connected to the top of the shuttle kiln body. An air outlet pipe is provided on the other side of the box body. The air outlet pipe passes through the waste heat recovery box and is connected to the spiral metal pipe.

[0018] In the above technical solution, the flue gas generated during the firing of Jun porcelain in the shuttle kiln can flow through the exhaust pipe, and the flue gas reaches the box in advance for dust removal.

[0019] This utility model provides an energy-saving shuttle kiln for Jun porcelain, which has the following beneficial effects:

[0020] (1) By setting a spiral metal tube in the waste heat recovery box, the flue gas after dust removal can exchange heat with fresh air in the opposite direction when it passes through the spiral metal tube, thereby increasing the temperature of the combustion air, reducing fuel consumption in the combustion chamber, reducing energy consumption, and thus reducing the operating cost of the kiln. In addition, the spiral metal tube is connected to the serpentine tube. After the heat of the flue gas is initially recovered through the spiral metal tube, the remaining heat is used to heat the water tank through the serpentine tube, thereby improving the recovery efficiency.

[0021] (2) By installing a flue gas dust removal device, the filter screen can intercept large dust particles in the flue gas, reducing the subsequent treatment load. The activated carbon plate adsorbs fine particles, pollutants and odors, achieving synergistic purification of dust and harmful gases, thereby avoiding blockage of subsequent pipelines. The filter screen and activated carbon plate are connected to the box body by T-shaped plates and connected to the box cover by top plate, mounting plate and rivets, which is convenient for disassembly and replacement.

All are fixedly connected with mounting plates 236. The top side of the box body 23 is provided with a box cover 24 by rivets. Both ends of the box cover 24 are provided with T-shaped grooves 241. The outer walls of the T-shaped plates 233 and activated carbon plates 237 are slidably connected to the inner walls of the T-shaped grooves 241.

The mounting plates 236 are connected to the box cover 24 by rivets. By installing the flue gas dust removal device 2, the filter screen 234 can intercept large dust particles in the flue gas, reducing the subsequent treatment load. The activated carbon plates 237 adsorb fine particles, pollutants and odors, realizing the synergistic purification of dust and harmful gases, thereby avoiding the blockage of subsequent pipes. The filter screen 234 and activated carbon plates 237 are inserted into the box body 23 by T-shaped plates 233 and connected to the box cover 24 by the top plate 235, mounting plates 236 and rivets, which is convenient for disassembly and replacement.

[0030] like Figure 1 and Figure 2As shown, the waste heat recovery device 3 includes a waste heat recovery box 31. The inner wall of the waste heat recovery box 31 is provided with a ceramic fiber insulation layer. The waste heat recovery box 31 is located at the rear end of one side of the outer wall of the shuttle kiln body 1. A spiral metal tube 32 is installed inside the waste heat recovery box 31. A cold air inlet 33 is located at the front end of the waste heat recovery box 31, and an air inlet pipe 34 is located on the other side of the waste heat recovery box 31.

The flue gas reaches the box 23 in advance and is processed by the T-shaped plate 233 and the activated carbon plate 237 in sequence. Then, it enters the spiral metal pipe 32 through the exhaust pipe 25 and is fed into the waste heat recovery box 31 through the cold air inlet 33. This allows for reverse heat exchange with the fresh air, which increases the temperature of the combustion air and reduces fuel consumption in the combustion chamber. In addition, the spiral metal pipe 32 is connected to the serpentine pipe 36. After the heat of the flue gas is initially recovered through the spiral metal pipe 32, the remaining heat is used to heat the water tank 35 through the serpentine pipe 36, thereby improving the recovery efficiency.
