Description

Technical Field

[0001] The utility model relates to the technical field of kiln head covers, in particular to a kiln head cover which is easy to discharge impurities. Background Art

[0002] In many production industries such as building materials, metallurgy, chemical industry, and environmental protection, rotary drum equipment is widely used to perform mechanical, physical or chemical treatment on solid materials. This type of equipment is called a rotary kiln. The rotary kiln is a large rotary drum type of equipment, which is installed at a small angle and rotates at a low speed. At present, the kiln head cover of the rotary kiln consists of a single-body observation door on the front of the burner and a maintenance door on the side that can be rotated to open. In the actual production process, high-temperature large balls appear due to abnormal sintering of materials. In this case, the large side inspection door is usually opened manually to perform blocking operations or pull the large balls out of the kiln head hood for processing. The kiln head hood is wide in front and narrow on the side. The width of the inspection door on the side is limited by the width of the kiln head hood, and large balls with a diameter greater than the width of the kiln head hood cannot be pulled out of the kiln head hood for processing. When encountering this situation, it is often necessary to stop the burner and slow down the speed of the rotary kiln to manually process the high-temperature large balls in the kiln head hood. This method will affect the continuous production of the rotary kiln, reduce production efficiency, and cause waste of resources. Therefore, a kiln head hood that is easy to discharge impurities is proposed to solve the above problems. Utility Model Content

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0018] See also Figure 1-3 A kiln head hood for easily discharging impurities in the present application comprises a kiln head hood body 1, the front of which is open and provided with a double-door, a side door 12 is provided on the side of the kiln head hood body 1, and an adjustable bottom plate 13 is movably provided on the bottom wall of the kiln head hood body 1, so that the adjustable bottom plate 13 can change the degree of inclination toward the side door 12 or toward the main door 11 by adjusting the angle.

[0019] The kiln head hood is generally connected to the rotary kiln through a sealing flange cover. The modification of the kiln head hood is designed to solve the problem that aluminum ash is very likely to produce large ball impurities 3, or even super-large ball impurities 3 when sintered in a rotary kiln. The existing kiln head hood has a single-body observation window on the front for observing the internal situation, but has no impurity removal function. A rotatable inspection door is opened on the side to remove impurities. Since the kiln head hood is wide at the front and narrow at the side, the inspection door on the side cannot be designed to be wide enough, and large sintered materials are often unable to be discharged. In addition, the high temperature makes it easy to stick together, causing the discharge port to be blocked. The device changes the front observation window into a double-door door, the height and opening width of which are slightly larger than the diameter of the rotary cylinder 2 (i.e., the cylinder of the rotary kiln), so as to facilitate the rapid disposal of large balls and the entry and exit of auxiliary equipment into the kiln. At the same time, through the protection A side door 12 and a corresponding side impurity removal port 14 are left, so that when balls below 1.5 meters appear, they can be quickly discharged from the door without stopping the machine, so as to ensure the continuous production of the rotary kiln. Since the kiln head cover has two different outlets for removing impurities, in addition to relying on auxiliary equipment to remove impurities, the device can adjust the bottom plate 13 through a movable setting to change its horizontality, thereby changing its tilt direction from top to bottom, so that when the rotary cylinder 2 generates large balls, the bottom plate 13 is adjusted to tilt toward the main door 11, and the large balls placed on the bottom plate can be affected by gravity and slowly roll out of the main door 11. When the rotary cylinder 2 generates small balls, the bottom plate 13 is adjusted to tilt toward the side door 12, and the small balls placed on the bottom plate can be affected by gravity and slowly roll out of the side door 12, which reduces the difficulty of removing and can provide targeted auxiliary discharge.

[0020] Furthermore, telescopic members 131 are respectively provided under the four corners of the adjusting base plate 13 , so that when the telescopic members 131 are telescoped to change their own lengths, the horizontality of the adjusting base plate 13 is driven to change.

[0021] The device is provided with an extendable and shortenable telescopic member 131, so that the height of the four corners of the adjusting bottom plate 13 can be changed. If the telescopic member 131 close to the main door 11 is short and the telescopic member 131 far away is long, the adjusting bottom plate 13 is tilted toward the main door 11, thereby driving the large knot ball to roll toward the main door 11; if the two telescopic members 131 close to the side door 12 are short and the telescopic members 131 far away are long, the adjusting bottom plate 13 is tilted toward the side door 12, thereby driving the small knot ball to roll toward the side door 12, so as to facilitate the discharge of different materials.

[0022] Furthermore, it also includes a flexible connection part 132 , and the adjusting bottom plate 13 is connected to the inner wall of the kiln head hood body 1 through the flexible connection part 132 .

[0023] In order to enable the adjusting bottom plate 13 to adjust the horizontality, there is a certain distance between the four sides of the adjusting bottom plate 13 and the inner wall of the kiln head hood body 1. When the adjusting bottom plate 13 adjusts the horizontality, the distance and angle between the four sides and the inner wall of the kiln head hood body 1 change. If the adjusting bottom plate 13 is not connected to the inner wall, impurities may fall into the gap between the adjusting bottom plate 13 and the inner wall. Therefore, the device is provided with a flexible connecting part 132, so that the adjusting bottom plate 13 can be freely adjusted when it is movable, and is not affected by the connection relationship, and can prevent materials from falling into the gap between the adjusting bottom plate 13 and the inner wall.

[0024] Furthermore, an observation window 111 is provided on the main door 11 .

[0025] The device opens a small window of 1 meter square on the main kiln door to observe the situation inside the kiln at any time, so that the staff can clear the blockage of sintered materials in time.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
