Description

Technical Field

[0001] This utility model relates to the field of material powder selection technology, specifically a V-type powder classifier with uniform sieving. Background Technology

[0002] In existing cement production processes, V-type air classifiers are one of the key separation devices. However, traditional V-classifiers have significant shortcomings in terms of material distribution and air separation efficiency. Specifically, materials are often unevenly distributed when entering the V-classifier, resulting in poor air separation and high residue levels. This not only affects the quality and production efficiency of cement products but also increases energy consumption and production costs.

[0003] The existing Chinese utility model patent with publication number CN114160420A discloses a dynamic V-type air classifier comprising: a base; a sorting cylinder installed on the base, the sorting cylinder having an air inlet, an air outlet, a feed inlet, and a discharge outlet; wherein, the sorting cylinder includes a primary sorting cylinder and a secondary sorting cylinder communicating with the interior of the primary sorting cylinder, and a filter plate is provided at the connection between the primary and secondary sorting cylinders; the primary sorting cylinder has at least one set of grading plates, and the top of the secondary sorting cylinder is provided with a separation device, the execution end of the separation device extending into the secondary sorting cylinder. By setting a filter plate between the primary and secondary sorting cylinders, the sand and gravel are separated once, and then the sand and gravel entering the secondary sorting cylinder are separated a second time by the separation device. In this way, the fine powder in the sand and gravel is fully separated through two sorting processes, resulting in high-quality sand and gravel.

[0004] Based on the above patent search and the findings of existing equipment, V-type classifiers are one of the key separation devices in the current cement production process. However, traditional V-classifiers have significant shortcomings in terms of material distribution and air separation effect. Specifically, the material is often unevenly distributed when entering the V-classifier, resulting in poor air separation effect and high screen residue. This not only affects the quality and production efficiency of cement products, but also increases energy consumption and production costs. Furthermore, the inability to uniformly feed the material into the V-classifier during screening leads to uneven material screening within the V-classifier. All these problems affect the use of the device. Utility Model Content

[0019] 1. This utility model improves the air separation effect by adding an air inlet to the lower end of the outer shell of the powder separation structure component through the design of the detection equipment components. The airflow is made more uniform and stable through the two air inlets, thereby improving the air separation effect. The flow guiding and separating component is equipped with a storage tank, and multiple flow dividers are installed inside the storage tank. The upper end of the flow dividers is equipped with a flow guide plate.

The optimized V-separator equipment reduces screen residue while also reducing energy consumption and production costs, achieving green production. It effectively prevents the uneven distribution of materials when entering the V-separator equipment, which often leads to poor air separation effect and high screen residue. This not only affects the quality and production efficiency of cement products, but also increases energy consumption and production costs.

A control motor is installed at the upper end of the conveying frame, which starts the spiral inside the conveying frame to facilitate the uniform conveying of materials inside the conveying frame. An outlet is installed at the lower end of the conveying frame and at the upper end of the storage tank to facilitate the uniform conveying of materials into the storage tank for use. This effectively prevents uneven material feeding into the V-separator during material screening, which would otherwise lead to uneven material screening inside the V-separator.
