Description

Technical Field

[0001] The utility model relates to the field of cement production equipment, in particular to a preheater grading material lifting device. Background Art

[0002] In the cement production process, the raw materials are generally preheated by waste heat utilization equipment before the clinker is burned, so as to reduce the energy consumption of clinker burning and improve the quality of clinker burning. In the prior art, the preheater is generally a graded waste heat. In the process of dividing the materials from the previous level to the next level, the raw materials are further heated through the lifting plate to the next level. In this process, the more uniform the material dispersion is, the more conducive it is to improve the heat absorption effect of the material. The lifting plate in the existing technology adopts an ordinary inclined rectangular flat plate, the material dispersion uniformity is not ideal, and it is easy to gather on the lifting plate, affecting the waste heat absorption effect. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a preheater grading and lifting device which has a simple structure, low modification cost and can achieve full dispersion of materials.

[0004] The equipment includes a material lifting plate body, the material lifting plate body includes a connecting portion, and the connecting portion is in the form of a flat plate;

[0005] A material lifting part is integrally connected to the front of the connecting part, and the material lifting part is trapezoidal, with the front part wider than the rear part;

[0006] The material lifting part is provided with air holes.

[0007] The beneficial effect of the utility model is that the utility model solves the problem in the prior art that the lifting plate is easy to gather materials and has a poor material dispersion effect. By increasing the front width of the lifting plate and adding air holes, the problem of material aggregation can be better solved and the material dispersion effect can be greatly promoted. In particular, the equipment has a simple structure, low manufacturing or modification costs, and has greater promotion value. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The realization of the purpose, functional features and advantages of the utility model will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0012] Reference Figure 1The preheater grading material lifting device described in the utility model comprises a material lifting plate body, the material lifting plate body comprises a connecting portion 4, and the connecting portion 4 is in the form of a flat plate;

[0013] In front of the connecting portion 4, a material raising portion 1 is integrally connected and arranged. The material raising portion 1 is trapezoidal, and its front portion is wider than its rear portion.

[0014] The effect achieved by this is that, compared with the traditional rectangular flat plate, this equipment is equivalent to adding a wing plate, making the width of the lifting part 1 point larger, which is more conducive to material dispersion;

[0015] The material lifting part 1 is provided with air holes 2 .

[0016] The effect achieved in this way is that the process of the preheater is that the airflow goes upward and the material goes downward. The material is most likely to gather at the front end of the lifting plate body. After the lifting part 1 is opened, the aggregate is flushed away under the impact of the material airflow, thereby solving the aggregation problem and greatly promoting the material dispersion effect.

[0017] Furthermore, the array of air holes 2 is provided in plurality.

[0018] The effect achieved by this is to improve the dispersion effect of the material.

[0019] Furthermore, a plurality of Y-shaped supporting forks 3 are integrally connected to the connecting portion 4 .

[0020] The effect achieved by this is that the Y-shaped support fork 3 serves as a reinforcing rib of the burn-resistant material coating, thereby improving the strength of the burn-resistant coating.

[0021] Furthermore, an arc-shaped notch is centrally arranged at the front of the material lifting part 1, and the transition of the arc-shaped notch is smooth.

[0022] The effect achieved in this way is that this position is a position where materials are easily aggregated, and the gap can shorten the sliding of materials and further avoid aggregation.

[0023] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims.

[0024] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
