Description

Technical Field

[0001] The utility model relates to the technical field of thermal equipment, in particular to a cleaning device for a metal inner tank of a rotary kiln. Background Art

[0002] As a common industrial equipment, rotary kiln is widely used in various industries due to its ability to achieve uniform heating and high production efficiency. However, in the sintering process of certain specific materials, such as the sintering of lithium battery positive electrode materials, the raw materials contain a large amount of moisture and impurities, resulting in the generation of impurities such as tar during the sintering process. These impurities will adhere to the inner wall of the rotary kiln cylinder. Over time, these deposits will continue to increase, causing the thickness of the inner wall of the rotary kiln cylinder to increase, thereby reducing production capacity, increasing energy consumption, and affecting the normal operation of the rotary kiln.

[0003] In order to solve this problem, the rotary kiln cylinder must be cleaned and maintained regularly. At present, the inner wall of the rotary kiln cylinder is usually cleaned by spraying high-pressure water on it, and the sediment attached to the wall is washed away by the high-pressure water flow. However, in actual production, due to the high adhesion of impurities such as tar, the high-pressure water flow cannot effectively remove them, resulting in poor cleaning effect, and repeated flushing is required, resulting in a waste of water resources. Utility Model Content

[0004] To this end, the utility model provides a rotary kiln metal liner cleaning device, which is used to solve the technical problems of poor cleaning effect of the metal liner sediment of the rotary kiln in the prior art and waste of water resources.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A cleaning device for a rotary kiln metal liner comprises a base; the rotary kiln metal liner is rotatably arranged on the base; a water inlet cover is provided at the left end of the rotary kiln metal liner for closing the left end of the rotary kiln metal liner; a drainage cover is provided at the right end of the rotary kiln metal liner for closing the right end of the rotary kiln metal liner; a plurality of ceramic balls are placed in the rotary kiln metal liner; the water inlet cover is provided with a water inlet communicated with the rotary kiln metal liner; the drainage cover is provided with a drainage outlet communicated with the rotary kiln metal liner; a water inlet sealing cover is provided at one end of the water inlet away from the water inlet cover; a drainage outlet sealing cover is provided at one end of the drainage outlet away from the drainage cover; and a rotation driving device is also provided for driving the rotary kiln metal liner to rotate.

[0008] Optionally, the rotation drive device includes a reduction motor arranged on the base; the outer wall of the metal inner tank of the rotary kiln is provided with an inner tank sprocket; the output shaft of the reduction motor is provided with a driving sprocket; the driving sprocket is connected to the inner tank sprocket through a chain to drive the inner tank sprocket to rotate.

[0009] Preferably, a water inlet cover fixing flange is provided on the left side of the rotary kiln metal inner liner, and a drain cover fixing flange is provided on the right side; the water inlet cover is connected to the rotary kiln metal inner liner via the water inlet cover fixing flange; the drain cover is connected to the rotary kiln metal inner liner via the drain cover fixing flange.

[0010] Preferably, sealing rings are provided between the water inlet cover and the water inlet cover fixing flange and between the drain cover and the drain cover fixing flange.

[0011] Preferably, the diameter of the ceramic ball is larger than the aperture of the drain port.

[0012] The utility model has at least the following beneficial effects:

[0013] It is provided with a water inlet cover and a drainage cover. The water inlet cover seals the left end of the rotary kiln metal inner liner, and the drainage cover seals the right end of the rotary kiln metal inner liner. A plurality of ceramic balls are placed in the rotary kiln metal inner liner. The water inlet cover is provided with a water inlet, and the drainage cover is provided with a drainage outlet. A rotary drive device is also provided. When in use, a cleaning liquid is injected into the rotary kiln metal inner liner from the water inlet, and the rotary drive device is started. The rotary kiln metal inner liner rotates, and the sediment on the inner wall of the rotary kiln metal inner liner is quickly detached under the scouring of the cleaning liquid and the impact of the ceramic balls. The ceramic balls have the characteristics of high hardness, high wear resistance, low specific gravity, high polishing property, high mechanical strength, etc., and can remove surface attachments, oxides, sediments, grease and other pollutants. The ceramic balls will not damage the rotary kiln metal inner liner and can be reused. In addition, the cleaning device is carried out in a closed environment, does not require excessive water resources, and saves water resources.

[0014] It can be seen that the rotary kiln metal liner cleaning device of the utility model has the advantages of thorough cleaning, high cleaning cleanliness, high cleaning efficiency, saving water resources, and no loss of the liner. BRIEF DESCRIPTION OF THE DRAWINGS
