[0002] Ceramic sanitary ware refers to sanitary ware made of ceramic materials, mainly including toilets, wash basins, bathtubs, showers, urinals, etc. These products not only have a beautiful appearance, but also have excellent performance and durability, and are widely used in homes and commercial places. In terms of production technology, ceramic sanitary ware products go through multiple links such as raw material processing, molding, drying, firing, and inspection to ensure the stability and reliability of product quality. With the advancement of science and technology and people's pursuit of quality of life, ceramic sanitary ware products are also constantly innovating and improving to meet the diversified needs of the market. In traditional sanitary ceramic factories, there are two types of product wet blank drying, one is natural drying, and the other is high-temperature drying in the drying room. Ceramic blank drying equipment is an important equipment used to dry the finished ceramic blank in the ceramic production process. Its main purpose is to evaporate and discharge the moisture in the blank by controlling conditions such as temperature, humidity and airflow, so as to achieve effective drying of the ceramic blank. Ceramic blank drying equipment usually uses hot air or other heat sources for heating, and evaporates the moisture on the surface of the blank and diffuses it into the air by heat conduction and convection. The drying room of the equipment is generally equipped with heating devices, ventilation devices and control systems to ensure the uniformity and stability of the drying process. Drying in the drying room requires a certain temperature and humidity curve, gradually increasing the temperature to prevent cracking of the blank, and a humidifier is usually used for humidification.

[0020] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the utility model.

[0021] like Figure 1 A drying chamber humidification device shown includes a water source treatment device 1, a water storage device 2, and an atomizing nozzle 6. The water source treatment device 1, the water storage device 2 and the atomizing nozzle 6 are connected through a pipeline 9. Water enters the water storage device 2 after being purified by the water source treatment device 1, and enters the atomizing nozzle 6 through the water storage device 2 to control the temperature. The atomizing nozzle 6 is located in a drying chamber 5. Wet blanks are placed in the drying chamber 5. The drying chamber 5 is humidified by the atomizing nozzle 6.

[0022] In this embodiment, the water source treatment equipment 1 is directly connected to the tap water pipe. The water source treatment equipment 1 adopts an industrial water softener, which uses resin fillers inside to remove calcium and magnesium ions in the water, and filter out impurities such as mud, rust, etc. in the water. The industrial water softener contains ion exchange resin beds inside, and these resins are materials that highly absorb hardness minerals. When hard water passes through the water softener, it will first pass through the pretreatment system for degassing and desiliconization. Then, the water enters the main treatment system, i.e., the ion exchange resin bed. Here, the calcium and magnesium ions in the water exchange ions with the sodium ions on the resin. The resin adsorbs the calcium and magnesium ions and releases an equal amount of sodium ions into the water. In this way, the calcium and magnesium ions in the water are removed, and the sodium ion content increases, thereby achieving water softening. After the ion exchange process, the softened water is output from the equipment. At the same time, as time goes by, the sodium ions in the ion exchange resin will gradually decrease, while the calcium and magnesium ions accumulated on the resin will increase. When the softening capacity of the resin bed weakens, a regeneration process is required, that is, using a specific regeneration agent (such as table salt) to restore the exchange capacity of the resin to ensure the continuous and stable operation of the water softener.

[0023] There are two water source treatment devices 1, one for use and one for reserve, to prevent damage and enable timely replacement without delaying the humidification process. By filtering impurities such as mud in the water, the water that finally enters the atomizing nozzle 6 through the pipe 9 contains very little scale and impurities, which is not easy to cause blockage, thus saving maintenance costs.

[0024] The treated water in the water source treatment equipment 1 enters the water storage equipment 2 through the pipeline 9. In the present embodiment, the water storage equipment 2 comprises a hot water tank 201 and a normal temperature water tank 202. The treated water enters the hot water tank 201 and the normal temperature water tank 202 respectively. The hot water tank 201 and the normal temperature water tank 202 are both provided with a liquid level gauge and an electric valve. When the water level in the hot water tank 201 and the normal temperature water tank 202 is too low, the electric valve is started to replenish the hot water tank 201 and the normal temperature water tank 202 to ensure that subsequent water supply can always be provided. The water outlets of the hot water tank 201 and the normal temperature water tank 202 are collected together, and a temperature control regulating valve 3 is installed. The temperature control regulating valve 3 can automatically adjust the ratio of the hot water tank 201 and the normal temperature water tank 202. The water flowing out after adjustment can change the temperature. This temperature can be changed according to the demand in the drying chamber 5 to ensure that the water entering the drying chamber 5 for humidification reduces the impact on the temperature in the drying chamber 5. Reducing this variable can more accurately control the temperature in the drying chamber 5 to ensure the final quality of the wet blank.

[0025] In this embodiment, a pipe 9 is connected after the temperature control regulating valve 3, and a pressurized water pump 4 is provided on this section of the pipe 9. The pressurized water pump 4 is used to spray water from the atomizing nozzle 6. A plurality of rows of atomizing nozzles 6 are provided in the drying chamber 5, specifically three rows in this embodiment. Each row is connected by a pipe 9, and an electric ball valve 8 is provided at the water inlet. The electric ball valve 8 of each row works independently and can control the corresponding atomizing nozzle 6 to spray water, so that humidification can be performed at different positions according to needs.

[0026] In this embodiment, a control cabinet 7 is also provided. The control cabinet 7 uniformly controls the electric valve, the temperature control regulating valve 3, the pressure water pump 4, and the electric ball valve 8 in the water storage device 2, and uniformly handles them according to different situations to ensure that each workstation works independently and the humidity in the drying chamber 5 is guaranteed. The pipeline 9 and the atomizing nozzle 6 in this embodiment can be replaced with the original old parts, which reduces the investment in equipment and greatly reduces the cost.

[0027] Working principle: put the wet blank into the drying chamber 5 for drying, turn on the tap water, the tap water enters the water source treatment equipment 1, and the large particles of impurities such as calcium and magnesium ions, mud, rust, scale, etc. in the tap water are filtered out through several resin fillers. After the filtration is completed, the water enters the hot water tank 201 and the normal temperature water tank 202. The hot water tank 201 heats the water, and the cold water and hot water reach a fixed temperature through the regulation of the temperature control valve 3, and then continue to flow through the pipeline 9 through the pressure water pump 4. The pressure water pump 4 pressurizes the water through the pressure water pump 4 and reaches different electric ball valves 8 respectively. The corresponding electric ball valve 8 is opened according to different position requirements, and the atomization nozzle 6 is used for atomization and humidification.

[0028] The utility model is further described above with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the utility model. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the utility model.
