Description

Technical Field

[0001] This utility model relates to the field of ceramic kiln technology, specifically to an energy-saving and environmentally friendly ceramic kiln. Background Technology

[0002] A kiln is a piece of equipment made of refractory materials used to fire ceramic products; it is an essential facility in the process of pottery making. Over tens of thousands of years of ceramic firing history, humankind has accumulated a wealth of kiln styles and experience. From open-air firing and pit firing in primitive societies to dome-shaped rising-flame round kilns, semi-downdraft horseshoe-shaped kilns, and egg-shaped kilns, and then to modern indoor gas kilns and electric kilns, kiln technology has continuously improved and developed.

[0003] The primary function of a ceramic kiln is to fire ceramic products. The kiln uses a high-temperature environment to evaporate moisture from the ceramic blank, burn organic matter, and crystallize inorganic matter, ultimately forming a hard ceramic product. Furthermore, there are various types of ceramic kilns, including wood-fired kilns, coal-fired kilns, gas-fired kilns, and electric kilns, each with its unique characteristics and applicable scenarios. For example, wood-fired kilns (wood-fired kilns) use the heat generated by burning wood to fire ceramics, while electric kilns use electric current for heating, making them suitable for artistic creations and small-scale production that require precise temperature control.

[0004] According to the authorization announcement number CN 210154351 U, a high-efficiency energy-saving ceramic kiln is disclosed, including a kiln body. Several electric heating tubes are connected to the inner wall of the kiln body. Fireproof and heat-insulating cotton is installed between the electric heating tubes and the kiln body. A placement platform is fixedly connected to the bottom of the kiln body. A waste heat recovery device is installed above the kiln body, with one end connected to an exhaust pipe. A controller is fixedly connected to the outer side of the kiln body. A door panel is movably connected to one side of the kiln body. Fireproof and heat-insulating cotton is fixedly connected to the side of the door panel closest to the kiln body. A cavity is opened in the door panel, and a piston is installed inside the cavity. The piston is fixedly connected to a movable rod. A feeding pipe is installed above the cavity, with a sealing plug connected to the end of the feeding pipe away from the cavity. A pushing mechanism is installed below the cavity.

[0005] Existing ceramic kilns cannot effectively treat the exhaust gas generated during use, resulting in the waste of usable resources within the exhaust gas and causing environmental pollution. Therefore, a new energy-saving and environmentally friendly ceramic kiln is needed. Utility Model Content

[0006] The purpose of this utility model is to provide an energy-saving and environmentally friendly ceramic kiln, which filters the exhaust gas discharged from the kiln through a filter assembly and recovers the waste heat of the exhaust gas through a heat exchange box, thereby avoiding the waste of available resources and protecting environmental safety, thus solving the technical problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An energy-saving and environmentally friendly ceramic kiln includes a kiln body, inside which several sets of placement plates are installed, and a heating chamber is opened in the middle of the kiln body, inside which several sets of heating wires are symmetrically installed.

[0010] The output end of the second air pump is equipped with a delivery pipe, the output end of the delivery pipe is equipped with a heat exchange box, a connecting pipe is installed through the side of the heat exchange box, the output end of the connecting pipe is installed through the side of the kiln body, and a third air pump is installed in the middle of the connecting pipe outside the heat exchange box.

[0011] Preferably, a first air inlet pipe is installed through the rear side of the kiln body, and a first air pump is installed in the middle of the first air inlet pipe outside the kiln body.

[0012] Preferably, the filter assembly includes a fixing plate installed on the side of the fixing frame, a sealing ring is installed at the connection between the fixing plate and the fixing frame, and a filter block is installed on the side of the fixing plate inside the fixing frame.

[0013] Preferably, the filter block includes a glass fiber layer, a PTFE layer, and an activated carbon layer, which are arranged sequentially along the filtration direction.

[0014] Preferably, a second air inlet pipe is installed through the top of the heat exchange box on the side of the conveying pipe, and a sealing cover is installed at the input end of the second air inlet pipe on the upper part of the heat exchange box.

[0016] Preferably, an exhaust pipe is installed at the output end of the heat exchange tube through one side of the heat exchange box, and a solenoid valve is installed at the middle of the exhaust pipe outside the heat exchange box.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] When the kiln fires ceramics, the generated exhaust gas enters the filter assembly inside the fixed frame through the gas collection hood for filtration, removing impurities and harmful gases. Then, it enters the heat exchange box through the conveying pipe for heat exchange, and finally, the heat-exchanged air returns to the kiln. This device, through the cooperation of the filter assembly and the heat exchange box, avoids the waste of usable resources inside the exhaust gas generated during ceramic kiln production, while protecting the environment from harm when the exhaust gas is discharged.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides: an energy-saving and environmentally friendly ceramic kiln, such as Figures 1-5As shown, the kiln body 1 includes several sets of placement plates 2 installed inside the kiln body 1. A heating chamber 3 is opened in the middle of the kiln body 1. Several sets of heating wires 4 are symmetrically installed inside the heating chamber 3. The placement plates 2 are used to place ceramics so that the ceramics can be fixed inside the kiln body 1. The heating chamber 3 is used to install the heating wires 4 to heat the kiln body 1.

[0027] A collection hood 7 is installed on the top of the kiln body 1. A fixing frame 8 is installed on the upper part of the collection hood 7. A filter assembly 9 is inserted and installed on the side of the fixing frame 8. A second air pump 10 is installed on the upper part of the fixing frame 8. The collection hood 7 is used to guide the exhaust gas generated by the kiln body 1 into the filter assembly 9 inside the fixing frame 8. The filter assembly 9 is used to filter the exhaust gas to prevent the exhaust gas from being discharged to the outside and causing pollution to the environment. The second air pump 10 is used to extract the exhaust gas inside the kiln body 1, filter it through the filter assembly 9, and finally deliver it to the heat exchange box 12 through the delivery pipe 11.

[0028] The output end of the second air pump 10 is equipped with a delivery pipe 11, the output end of the delivery pipe 11 is equipped with a heat exchange box 12, a connecting pipe 13 is installed through the side of the heat exchange box 12, the output end of the connecting pipe 13 is installed through the side of the kiln body 1, and the middle of the connecting pipe 13 is located outside the heat exchange box 12 and a third air pump 14 is installed. The delivery pipe 11 is used to transmit the filtered waste gas to the inside of the heat exchange box 12 for heat exchange. After the heat exchange is completed, the hot air is transported back to the inside of the kiln body 1 through the connecting pipe 13. The third air pump 14 is used to transport the heat-exchanged air into the inside of the kiln body 1.

[0029] Preferably, a first air inlet pipe 5 is installed through the rear side of the kiln body 1. A first air pump 6 is installed in the middle of the first air inlet pipe 5 outside the kiln body 1. The first air inlet pipe 5 is used to deliver cold air into the kiln body 1 to help the kiln body 1 to exchange air. The first air pump 6 is used to deliver outside air into the kiln through the first air inlet pipe 5.

[0030] Furthermore, the filter assembly 9 includes a fixing plate 91 installed on the side of the fixing frame 8. A sealing ring 92 is installed at the connection between the fixing plate 91 and the fixing frame 8. A filter block 93 is installed inside the fixing frame 8 on the side of the fixing plate 91. The fixing plate 91 is used to connect and fix to the fixing frame 8.

The filter block 93 is used to filter the exhaust gas. The filter assembly 9, which is inserted and installed, can be replaced at any time, increasing the convenience of the device.

[0031] Furthermore, the filter block 93 includes a glass fiber layer 931, a PTFE layer 932, and an activated carbon layer 933, which are arranged sequentially along the filtration direction. The glass fiber layer 931 intercepts and adsorbs dust and particles in the exhaust gas. When dust particles pass through the glass fiber layer, they collide directly with the fibers, and larger dust particles cannot pass through the gaps between the fibers. The PTFE layer 932 has a unique microporous structure, and its pore size can be precisely controlled, which can effectively intercept and capture extremely small particles in the exhaust gas, such as bacteria, viruses, and various industrial dusts. The activated carbon layer 933 can effectively adsorb various harmful gases in the exhaust gas, thereby purifying the air and improving air quality.

A sealing cover 16 is installed at the upper part of the heat exchange box 12 at the input end of the second air inlet pipe 15. The second air inlet pipe 15 is used to supply air into the heat exchange box 12, and the sealing cover 16 is used to block the second air inlet pipe 15, so that the heat exchange box 12 is in a sealed device, which facilitates the heat exchange of air.

[0033] Specifically, the heat exchanger box 12 is connected to the output end of the corresponding conveying pipe 11, and several sets of fins 18 are symmetrically installed on the outside of the heat exchanger box 12. The heat exchanger box 17 is used to replace the waste heat in the exhaust gas with the cold air inside the heat exchanger box 12, and the fins 18 are used to accelerate the heat exchange.

[0034] More specifically, an exhaust pipe 19 is installed on one side of the heat exchanger tube 17 through the output end of the heat exchanger 12. A solenoid valve 20 is installed in the middle of the exhaust pipe 19 outside the heat exchanger 12. The exhaust pipe 19 is used to discharge the filtered and heat-exchanged exhaust gas, and the solenoid valve 20 is used to control the discharge of the exhaust pipe 19.
