[0003] In the prior art, the traditional and widely used production process of ceramic raw materials is a wet powder making process, that is, various raw materials are ball-milled to obtain a slurry with a moisture content of 30-37wt%, homogenized, sieved and iron removed, and then spray-dried to obtain a powder with a moisture content of 5.5-7%. This powder making process is the most mature, with good powder performance, but high energy consumption. And because the slurry has a high viscosity and a slow conveying speed, it is difficult to improve production efficiency. Pipelines are also prone to blockage accidents, requiring frequent maintenance and cleaning.

Although the above equipment scheme can circulate and dry the slurry to avoid the sticking of the divided materials in the drying furnace, it cannot solve the problem of low drying efficiency and easy blockage of the slurry conveying pipeline.

[0005] In view of this, it is necessary to improve and develop related equipment for ceramic slurry spray drying in order to improve the slurry delivery speed and avoid clogging of the delivery pipeline. Utility Model Content

[0008] Furthermore, the slurry conveying pipe is coiled in a spring-like spiral and is vertically installed in the heating tank.

[0009] Furthermore, a slurry input port is arranged at the top of the slurry conveying pipe, and a slurry output port is arranged at the bottom.

[0010] Furthermore, a hot water inlet is provided at the bottom of the heating tank, and a hot water outlet is provided at the top, and both the hot water inlet and the hot water outlet are connected to the hot water circulation module through pipelines.

In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features.

[0029] like Figures 1 to 3 As shown, this embodiment provides an anti-clogging ceramic cold slurry heating mechanism, including a slurry storage tank 1, the slurry storage tank 1 pipeline is connected to a cold slurry heating module 2 and a mud pump 3, the output end of the mud pump 3 can be connected to a dry powder making device 4, the cold slurry heating module 2 includes a slurry delivery pipe 201 and a heating tank 202, the output end of the slurry delivery pipe 201 is connected to the input end of the mud pump 3, the heating tank 202 is wrapped on the outside of the slurry delivery pipe 201, and the heating tank 202 is connected to a hot water circulation module 5.

[0030] In actual use, the hot water circulation module 5 (hot water boiler) can be used to generate hot water and pass the slurry at room temperature into the cold slurry heating module 2 filled with hot water, so that the temperature of the slurry at room temperature rises, thereby increasing the flow rate of the slurry and avoiding blockage, and improving the processing efficiency of subsequent slurry spray drying and other powder making steps.

[0031] It is worth mentioning that the heat used by the hot water circulation module 5 for heating water can be recovered from the excess heat emitted by the drying and powder making equipment 4 or other ceramic production equipment, so as to reduce the operating energy consumption of the equipment.

[0032] The slurry conveying pipe 201 is coiled in a spring-shaped spiral and is vertically installed in the heating tank 202. There is a large contact area between the slurry conveying pipe 201 coiled in a spring-shaped spiral and the hot water in the heating tank 202, which can ensure that the slurry is fully heated by heat transfer.

[0033] The top of the slurry conveying pipe 201 is provided with a slurry input port 203, and the bottom is provided with a slurry output port 204. The slurry conveying pipe 201 placed vertically and conveying downward can use gravity to increase the conveying speed of the slurry and prevent the slurry from sticking and clogging in the slurry conveying pipe 201.

[0034] The bottom of the heating tank 202 is provided with a hot water inlet 205, and the top is provided with a hot water outlet 206, and the hot water inlet 205 and the hot water outlet 206 are both connected to the hot water circulation module 5 through pipelines. After heating the room temperature slurry, the hot water whose temperature drops enters the hot water circulation module 5 again through the hot water outlet 206 for heating. The hot water and the room temperature slurry are heat exchanged in a reverse flow manner, which has a good effect and stable temperature.

[0035] The hot water circulation module 5 includes a hot water exchange pipe, which is arranged on the kiln. The hot water circulation module 5 can recycle the excess heat generated by the kiln for producing ceramics, thereby reducing the energy consumption of the equipment.

[0036] The top of the heating tank 202 is connected to an overflow pipe 6, and the bottom is connected to a drain pipe 7. The output ends of the overflow pipe 6 and the drain pipe 7 are both connected to a downpipe 8. The overflow pipe 6 can automatically discharge the hot water overflowing due to thermal expansion and contraction, avoiding the tank body from bursting due to excessive water pressure in the heating tank 202, thereby improving the safety and service life of the equipment. The drain pipe 7 facilitates the discharge of dirt deposited at the bottom of the heating tank 202, avoiding the dirt from reducing the heat transfer efficiency between the hot water and the slurry in the slurry conveying pipe 201. The integrated downpipe 8 facilitates workers to lay pipelines.

[0037] The inner wall of the heating tank 202 is provided with a liquid level sensor 9 at the lower side of the overflow pipe 6, and the top of the heating tank 202 is connected with a water supply pipe 901, and an electric control valve 902 is provided on the water supply pipe 901, and the electric control valve 902 is electrically connected to the liquid level sensor 9. Since the overflow pipe 6 is provided to automatically discharge overflowing water and gas, it is easy to cause insufficient water, so the liquid level sensor 9 is provided to link the electric control valve 902 to open when the water level is detected to be low, so as to realize the automatic water replenishment function and reduce the maintenance difficulty of the equipment.

[0038] The heating tank 202 includes a stainless steel layer, and an aluminum silicate fiber layer and a steel plate layer are wrapped on the outside of the heating tank 202. The heating tank 202 made of stainless steel has a stable structure and a long service life, and the aluminum silicate fiber layer and the steel plate layer have a good thermal insulation effect.

[0039] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementation modes. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. That is, all equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
