Description

Technical Field

[0001] The utility model relates to the technical field of rotary kilns, in particular to a material lifting plate for a drying rotary kiln. Background Art

[0002] A rotary kiln is a rotary calcining kiln (commonly known as a rotary kiln), which belongs to the category of building materials equipment. Rotary kilns can be divided into cement kilns, metallurgical chemical kilns and lime kilns according to the materials they process. Rotary kilns are widely used, and rotary kilns are often used to dry coal during coal processing.

[0003] The lifting plate is a part installed inside the rotary kiln. When the rotary kiln drives the material to rotate, the material is lifted up by the lifting plate so that the material can be dried better.

[0004] Referring to the Chinese patent 200720173178.1, a lifting plate for a rotary kiln is disclosed, characterized in that the lifting plate is a vertical angle plate with a right-angle "turn" type cross section, and a fixed through hole is opened on the "turn" handle end flat plate of the lifting plate. The utility model is a new type of special wear-resistant and high-temperature resistant lifting plate added to the tail of the lime kiln, which greatly improves the decomposition rate of powder and fine materials in the kiln, and at the same time can reduce the inlet temperature of the electric dust collector, improve the heat utilization rate of the rotary kiln, achieve the purpose of energy saving and consumption reduction, and can save the water washing and screening process of lime, and has great practical application value.

[0005] The disclosed patent has a fixed shape, resulting in a fixed lifting angle, which cannot be adjusted according to different usage requirements. Therefore, we have developed a lifting plate for a drying rotary kiln that is easy to adjust and can adjust the lifting angle according to different requirements to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0006] The utility model aims to propose a lifting plate for a drying rotary kiln, which solves the problem that the existing lifting plate has a fixed shape and a fixed lifting angle and cannot adjust the lifting angle according to different use requirements.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] On the basis of the above scheme and as a preferred scheme of the above scheme: the upper end of the base is provided with a first arcuate surface, the bottom of the adjustable lifting plate is provided with a second arcuate surface, and the first arcuate surface is tangent to the second arcuate surface.

[0010] On the basis of the above solution and as a preferred solution of the above solution: two fastening bolts are installed on the base.

[0011] On the basis of the above scheme and as a preferred scheme of the above scheme: the limiting mechanism includes: a threaded sleeve, a toggle rod, a threaded rod and a limiting rod, the threaded sleeve is rotatably connected to the right side of the base, a plurality of toggle rods are fixed to the outside of the threaded sleeve, a threaded rod passing through the threaded sleeve is installed in the threaded sleeve, a limiting rod inserted into the base is fixed to the lower end of the threaded rod, the limiting rod is slidably connected to the base, and a plurality of sockets for inserting the threaded rods are evenly distributed on the turntable.

[0012] On the basis of the above scheme and as a preferred scheme of the above scheme: the angle between two adjacent jacks is 10°.

[0013] On the basis of the above scheme and as a preferred scheme of the above scheme: a limiting slide groove for the limiting rod to move up and down is arranged on the base.

[0014] On the basis of the above scheme and as a preferred scheme of the above scheme: the base, the adjustable lifting plate, the pin shaft and the turntable are all made of aluminum alloy.

[0015] In order to solve the problem that the existing lifting plate has a fixed shape and a fixed lifting angle, and the lifting angle cannot be adjusted according to different usage requirements, the utility model has the following beneficial effects:

[0016] When the lifting plate for a drying rotary kiln of the utility model is used, the base is fixed to the rotary kiln body by fastening bolts so that it can be disassembled and replaced in case of subsequent damage; the threaded sleeve is driven to rotate by twisting the toggle rod, and the threaded rod is driven to move by the rotation of the threaded sleeve, so that the threaded rod is moved out of the insertion hole, and then the adjustable lifting plate is rotated to adjust the angle of the adjustable lifting plate to meet different usage requirements. After adjustment, the threaded sleeve is rotated again, and the threaded rod is driven to be inserted into the insertion hole by the rotation of the threaded sleeve, so that the turntable, the pin shaft and the adjustable lifting plate are fixed.
