Description

Technical Field

[0001] This utility model relates to the field of ceramic production equipment technology, and in particular to a shaping device for processing ceramic handicrafts. Background Technology

[0002] During the processing of ceramic handicrafts, a shaping stage is required, including steps such as drying and preheating, to remove moisture from the blank and improve its strength. In existing technologies, drying and preheating are usually carried out using separate equipment, which consumes a lot of energy and has low thermal efficiency. The high-temperature waste heat exhaust gas generated by the drying box is often directly emitted, which not only wastes a lot of thermal energy but also causes thermal pollution and potential dust pollution to the environment. At the same time, the preheating box requires additional energy for heating, increasing operating costs. Utility Model Content

[0003] To overcome the technical defects of the existing technology, this utility model provides a shaping device for ceramic crafts processing, which can utilize waste heat from exhaust gas to reduce energy consumption and environmental pollution.

[0004] The technical solution adopted by this utility model is: a shaping device for processing ceramic handicrafts, including a base and a drying box and a preheating box both disposed on the base. The drying box is equipped with a heating tube. The accommodating cavity of the preheating box is connected to the drying box through an air supply pipe. An exhaust fan is provided on the air supply pipe. The exterior of the preheating box is equipped with a heat insulation layer. The heat insulation layer is connected to the air supply pipe through a waste gas inlet pipe. The top of the accommodating cavity of the preheating box is connected to a waste gas purification device through an exhaust pipe.

[0005] Preferably, the exhaust gas inlet pipe is equipped with a regulating valve.

[0006] Preferably, the insulation interlayer is connected to the air outlet duct via an air supply pipe.

[0007] Preferably, the preheating box is equipped with a perforated shelf for placing ceramic blanks, and the outlet of the air supply duct is located below the perforated shelf.

[0008] Preferably, the drying oven is equipped with an air distribution mechanism, which includes a circulating fan mounted on the oven wall and a perforated air distribution plate mounted below the circulating fan.

[0009] Preferably, the exhaust gas purification device includes a condenser, a gas-water separator, and an activated carbon adsorption tower connected in sequence, and the exhaust pipe is connected to the air inlet of the condenser.

[0010] Preferably, the cooling water outlet of the condenser is connected to a water storage tank via a pipeline.

[0011] The beneficial effects of this utility model are as follows: The shaping device for ceramic crafts processing of this utility model can guide the high-temperature waste gas in the drying oven to the preheating box to preheat the ceramic blank in the preheating box. When the preheated ceramic blank is transferred to the drying oven for drying, the drying effect can be achieved more quickly, saving heating time. At the same time, the heat insulation jacket design on the outside of the preheating box effectively reduces heat loss and further improves the heat energy utilization rate. Finally, the exhaust gas can reduce environmental pollution after purification. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings: like Figure 1 and Figure 2 As shown, this embodiment provides a shaping device for processing ceramic handicrafts, including a base 1. A drying chamber 3 and a preheating chamber 2 are fixedly installed on the base 1. The drying chamber 3 is equipped with a heating tube 301 to generate hot air to dry the ceramic blank. The accommodating cavity of the preheating chamber 2 is connected to the drying chamber 3 through an air supply pipe 4. An exhaust fan 5 is installed on the air supply pipe 4. When the exhaust fan 5 is working, it draws the hot air in the drying chamber 3 into the accommodating cavity of the preheating chamber 2 to preheat the ceramic blank.

[0016] In this embodiment, the preheating box 2 is provided with an insulation jacket 201 on the outside. The insulation jacket 201 is connected to the air supply pipe 4 through an exhaust gas inlet pipe 6. The exhaust gas inlet pipe 6 is provided with a regulating valve 7 for regulating the flow rate of exhaust gas introduced into the air supply pipe 4 from the insulation jacket 201. The top of the accommodating cavity of the preheating box 2 is connected to an exhaust gas purification device through an exhaust pipe 8. The insulation jacket 201 is also connected to the exhaust pipe 8 through a make-up air pipe 9 for balancing the airflow in the insulation jacket 201.

[0017] In this embodiment, the preheating box 2 is equipped with a hollow shelf 202 for placing ceramic blanks. The outlet of the air supply duct 4 is located below the hollow shelf 202. Hot air blows from the bottom up onto the blanks to ensure uniform preheating. The drying box 3 is equipped with an air distribution mechanism, which includes a circulating fan 303 mounted on the box wall and a porous air distribution plate 302 located below the circulating fan 303. The circulating fan 303 promotes hot air circulation, and the porous air distribution plate 302 ensures uniform diffusion of hot air, thereby improving drying efficiency.

[0018] The exhaust gas purification device of this embodiment includes a condenser 10, a gas-liquid separator 11, and an activated carbon adsorption tower 12 connected in sequence. The exhaust pipe 8 is connected to the air inlet of the condenser 10. The exhaust gas first enters the condenser 10 for cooling. After the moisture condenses, it is separated by the gas-liquid separator 11. The dried gas then passes through the activated carbon adsorption tower 12 to adsorb harmful substances before being discharged. The cooling water outlet of the condenser 10 is connected to a water storage tank 13 through a pipeline. The collected condensate can be used for other purposes.

[0019] In this embodiment, a shaping device for ceramic crafts processing is used to place the shaped wet ceramic blank into a drying chamber 3. The heating tube 301 and the air distribution mechanism are activated to dry the blank evenly. The blower 5 transports the high-temperature waste heat gas in the drying chamber 3 to the preheating chamber 2 through the air supply pipe 4. The high-temperature waste heat gas enters from the bottom of the preheating chamber 2 and preheats the cold blank on the hollow shelf 202. During this process, some of the hot waste gas in the accommodating cavity will be heated through convection and conduction through the inner wall of the preheating chamber 2, so that the air in the insulation layer 201 outside the chamber is heated.

[0020] Meanwhile, to precisely control and enhance the insulation effect, the air supply pipe 9 actively diverts the relatively high-temperature exhaust gas from the outlet duct 8 and introduces it into the insulation jacket 201. This portion of exhaust gas forms a dynamic insulation air curtain within the insulation jacket 201, effectively reducing heat loss from the containment cavity to the outside environment through the box wall. Subsequently, under the precise control of the negative pressure suction generated by the induced draft fan 5 and the regulating valve 7, this portion of exhaust gas within the insulation jacket 201, which has already insulated the box and whose temperature is still higher than the ambient air, is quantitatively extracted through the exhaust gas inlet pipe 6 and returned to the insulation jacket. In the main air supply duct 4, this measure realizes the secondary recovery of residual heat in the heat-insulated exhaust gas. The return exhaust gas mixes with the higher-temperature waste heat fresh air from the drying box 3 in the air supply duct 4, which not only increases the initial temperature of the mixed gas entering the preheating box 2 and optimizes the preheating conditions, but also realizes the cascade and recycling of thermal energy, further reducing the total energy consumption of the system. The exhaust gas with a lower temperature after preheating enters the exhaust gas purification device through the exhaust duct 8, and is processed in sequence through the condenser 10, the gas-water separator 11 and the activated carbon adsorption tower 12 to achieve clean emission.

Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention.
