Description

Technical Field

[0001] The invention provides a discharge plate for a vertical mixer and a preparation process thereof, belonging to the technical field of discharge plates for mixers. Background Art

[0002] A stirring rod is provided in the vertical mixer, and a discharge hole is opened at the bottom. A discharge plate is installed at the bottom of the discharge hole. The bottom of the discharge plate rotates to intersect with the discharge hole, thereby closing and opening the discharge hole.

[0003] In the prior art, when the discharge plate opens and closes the discharge hole, there is a large friction problem due to the concrete, which causes great wear on the working surface of the discharge plate. The discharge plate needs to be treated with wear resistance. The treatment method is: a wear-resistant layer is processed on the surface of the discharge plate, or a wear-resistant material is used on the entire discharge plate to ensure the wear-resistant effect.

[0004] Prior art CN117168899A sampling device, dry-mixed mortar mixer and sampling control method, the prior art does not describe the opening and closing control in the description of the discharge door. Existing equipment such as vertical axis planetary mixers use discharge plates for discharge. Existing ones use integral and segmented discharge plates. The integral discharge plate is easy to be concentrated and easily worn when worn. Once the arc lining plate is worn, it is easy to cause leakage of the main machine. Replacement requires overall replacement, which has the problem of high replacement cost. The segmented discharge plate is installed in sections and installed on the base plate by bolts. On the one hand, concrete is easily accumulated in the gap, resulting in aggravated wear. On the other hand, during use, the closing performance is easily interfered by the residual concrete, which is easy to cause wear caused by concrete extrusion and long-term collision and extrusion at the bolts, resulting in the fall of the wear-resistant plate. Therefore, it is necessary to enhance the connection strength and overall performance of the segmented discharge plate to support and maintain the wear resistance of the discharge plate. Therefore, a discharge plate and preparation process for a vertical mixer of the present invention are proposed. Summary of the invention
