Description

Technical Field

[0001] The utility model relates to the field related to cement processing, and in particular to a material lifting device inside a mill. Background Art

[0002] Cement is a powdery, hydraulic inorganic gelling material, which becomes a slurry after being stirred with water. It can harden in the air or in water, and can firmly bond sand, stone and other materials together. In the process of cement processing, an in-grinding material lifting device is required.

[0003] The existing cement mill liner in the first bin is a corrugated liner, which has a poor lifting effect, a high steel ball installation capacity, and is not conducive to the control of cement mill power consumption. In addition, the existing liner is usually installed only by bolts. After long-term use, it is easy to loosen and fall off. The liner will fall off. Therefore, we make improvements on this and propose a mill lifting device. Utility Model Content

[0004] The purpose of the utility model is to solve the problems that the mill lining in the first bin of the existing cement mill is a corrugated lining, the material lifting effect is poor, the steel ball installation capacity is high, which is not conducive to the power consumption control of the cement mill, and the existing lining is usually installed only by bolts. After long-term use, it is easy to loosen and fall off, and the lining will fall off.

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

[0006] An in-mill material lifting device is used to solve the above problems.

[0009] As a preferred technical solution of the present application, the discharging mechanism includes a driving motor, and the driving motor is fixedly mounted on the surface of one side of the mounting tube, the output pipe of the driving motor is fixedly connected to a connecting rod, and a spiral blade is fixedly mounted on the surface of the connecting rod.

[0010] As a preferred technical solution of the present application, angle irons are fixedly installed on the surfaces of several of the lining plates, and several of the lining plates are fixedly connected to the inner wall of the cylinder by bolts.

[0011] As a preferred technical solution of the present application, the connecting mechanism includes a mounting block and a mounting groove, and the mounting block is fixedly mounted on the surface of one side of the lining, and the mounting groove is opened on the surface of the other side of the lining, the connection between the mounting block and the mounting groove is a snap-fit ​​connection, and a snap-fit ​​connection is formed between two adjacent linings.

[0012] As a preferred technical solution of the present application, a groove is provided on the surface of the upper side of the mounting block, and a clamping block is slidably connected inside the groove, a first spring is fixedly installed between the surface of the clamping block and the inner wall of the groove, and the surface on one side of the upper end of the clamping block is inclined, a sliding groove is provided on the upper side of the mounting groove, and the clamping block and the sliding groove are clamped in a clamping connection.

[0013] As a preferred technical solution of the present application, the slide groove is internally slidably connected to a sliding rod, and a connecting groove is provided on the outside of the slide groove, the connecting groove is internally slidably connected to a connecting plate, and the connecting plate is fixedly connected to the sliding rod, and a second spring is fixedly installed between the surface of the connecting plate and the inner wall of the connecting groove.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] In the scheme of this application:

[0016] 1. By setting lining plates and angle irons, the corrugated lining plates are replaced with flat lining plates. The corrugated lining plates may cause the materials to be retained or blocked during the unloading process. The flat lining plates can provide better lifting effect and make the materials unloaded smoothly. With the angle irons on the surface of the lining plates, the materials can be better ground with the internal steel balls, which can appropriately reduce the installed capacity of steel balls and avoid high power consumption of cement mill caused by high steel ball loading, which is not conducive to production power consumption control.

[0017] 2. Through the use of the connecting mechanism, when installing the liner, the mounting block on one surface is inserted into the mounting groove on the other surface of the adjacent liner. Since the surface on one side of the upper end of the block is inclined, when the mounting block moves, the inclined surface will drive the block to slide into the groove and cause the first spring inside to deform. When the block is aligned with the slide groove, the elastic force of the first spring can push the block upward and make the block inserted into the slide groove, which is convenient for assembling the two liners and prevents the liner from falling off after the bolts become loose and fall off.
