[0002] Multiple drying kilns are arranged side by side, and an interface is set on the top of each drying kiln for connecting the fan. Each kiln body is equipped with a blower, which blows hot air into the drying chamber of the drying kiln to increase the temperature inside the drying chamber to 200-300℃; while the blower blows hot air into the drying chamber, the corresponding airflow in the drying chamber will also be discharged to the outside.

[0003] Since the airflow in each drying chamber will be discharged outside, part of the airflow in the drying kiln at the rear will flow into the first drying kiln, resulting in excessive airflow in the first drying kiln; however, the number of fans is fixed at one, and the maximum flow rate of one fan cannot reach the exhaust volume required by the first drying kiln; the airflow velocity in the first drying kiln is too small to meet the requirements, and smoke leakage will occur, affecting the quality and progress of ceramic production.

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0028] See also Figure 1 to Figure 2 , the figure shows a multi-layer drying kiln with an independent dehumidification control component at the kiln head, including: a kiln body 10, a plurality of kiln bodies 10 are connected in sequence; a plurality of conveying components 20, used to horizontally convey the ceramic products to be processed in the middle of the kiln, the conveying components 20 are horizontally arranged in the kiln body, and a drying channel 11 is formed between every two adjacent conveying components 20; a main dehumidification component 30, arranged on the top of the kiln body 10, and the main dehumidification component 30 is connected to the drying channel 11; an auxiliary dehumidification component 50, used to extract wet flue gas inside the first kiln body 10; an auxiliary connecting component 40, one end of the auxiliary connecting component 40 is connected to the middle of the top surface of the first kiln body 10, and the other end is connected to the auxiliary dehumidification component 50; an auxiliary driving component 60, the auxiliary driving component 60 drives the auxiliary dehumidification component 50 to perform auxiliary dehumidification in the kiln head.

[0029] In the present invention, each kiln body 10 is equipped with a fan, and an auxiliary dehumidification component 50 is added to the kiln head to discharge the excessive moisture flow inside the first section of the kiln body; the smoke leakage phenomenon is effectively prevented, and the smooth dehumidification work of ceramic heating is ensured; the internal flow rate of the first section of the kiln body 10 is too fast, and the excess moisture and smoke are discharged to the outside, ensuring smooth airflow.

[0030] Furthermore, the conveying assembly 20 includes a conveying motor, a conveying gear 22, and a plurality of conveying rollers 23. The conveying motor and the conveying gear 22 are connected by a meshing transmission. The conveying motor drives the conveying gear 22 and the conveying roller 23 in turn, thereby driving the ceramic product to be evenly dried inside the kiln body.

[0031] A heating component 12 is disposed in the drying channel 11 ; the heating component 12 is used to uniformly heat the product inside the kiln body 10 .

[0032] The main dehumidification component 30 includes a main dehumidification fan 31, and the air inlet and outlet pipes of each two adjacent main dehumidification fans 31 are staggered in opposite directions; the main dehumidification fan 31 is also driven by a main drive motor 33, and the connection is also sealed by a main seal 34; the main dehumidification component 30 also includes a main dehumidification pipe 32, one end of a plurality of main dehumidification pipes 32 are staggeredly connected to the left and right ends of the drying channel 11 of each kiln body 10, and the discharge port of the main dehumidification fan 31 is vertically upward. The above arrangement of the positions of the main dehumidification fans 31 makes the wet flue gas discharged to the outside more uniform and the humidity of the whole environment moderate; it prevents one side of the kiln body 10 from being too humid, and excessive water vapor accumulates into water droplets to affect the processing environment.

[0033] Furthermore, the auxiliary connection component 40 is an auxiliary dehumidification pipe 41 which is tilted, and the tilt angle of the auxiliary dehumidification pipe 41 is 30-60 degrees; preferably, the tilt angle of the auxiliary dehumidification pipe 41 is 45 degrees, which is convenient for guiding the water vapor in the kiln head to the air inlet of the auxiliary dehumidification fan 51.

[0034] The auxiliary dehumidification component 50 is an auxiliary dehumidification fan 51, which is a centrifugal fan, and the air outlet pipe of the auxiliary dehumidification fan 51 discharges air vertically upward. The flow rate of the auxiliary dehumidification fan 51 needs to be moderate, and the flow rate cannot be set to be high, because a high flow rate will also cause the hot air to be extracted; therefore, it is only extracted in the first kiln furnace to ensure that the overall dehumidification smoke of the drying kiln is moderate and the air flow is smooth without smoke leakage.

[0035] The auxiliary drive assembly 60 includes an auxiliary drive motor 61, an auxiliary reducer 62, and an auxiliary transmission shaft 63. The auxiliary drive motor 61 drives the auxiliary reducer 62 and the auxiliary transmission shaft 63 in turn, thereby driving the auxiliary dehumidification fan 51 to start dehumidification. The above auxiliary drive assembly 60 is driven by a reduction motor, which can well control the wind speed and volume of the auxiliary dehumidification fan 51, ensuring the discharge of an appropriate amount of excess moisture from the kiln head.

[0036] Furthermore, an auxiliary seal 71 is provided at the connection between the auxiliary transmission shaft 63 and the auxiliary dehumidification fan 51. The overall cross-section of the auxiliary seal 71 is a horizontal herringbone shape after rotating 90 degrees. The auxiliary seal 71 is located on the upper part of the outer ring surface of the auxiliary transmission shaft 63. The above auxiliary seal 71 ensures a tight transmission connection between the transmission shaft and the auxiliary dehumidification fan 51.

[0037] An auxiliary support is provided on the outer annular surface of the auxiliary transmission shaft 63 on the auxiliary drive motor 61 side; the drying kiln also includes an auxiliary support 70.

[0038] The auxiliary support member includes a fixed support frame 72 and a plurality of sealing bolts 73. The bottom cross-section of the fixed support frame 72 is M-shaped, and the sealing bolts 73 are vertically fastened to the top of the fixed support frame 72. The above auxiliary support members prevent external airflow from entering the periphery of the auxiliary transmission shaft 63, thereby hindering the rotational power of the auxiliary transmission shaft 63.
