Description

TECHNICAL FIELD

[0001] The utility model relates to a mineral slag micro powder selects powder technical field, and specifically relates to a kind of anti-blocking structure for mineral slag micro powder selects powder device. BACKGROUND

[0002] Mineral slag micro powder selects powder is the important link of mineral slag processing, and the particles of the crushed mineral slag are finely separated according to size by special equipment, to ensure the uniformity and activity of the finished powder, and the process can efficiently screen the fine powder meeting the requirements, while the coarse particles are reprocessed in the furnace, which not only improves the resource utilization rate, but also ensures the performance stability of the final product. When the micro powder after selection is used as a building material additive, it can significantly improve the compactness, compressive strength and durability of concrete, and is one of the core technologies for improving the value of industrial solid waste resource utilization.

[0003] In the existing mineral slag micro powder, the coarse particles and fine powder will naturally stratify due to the weight difference during the feeding process. The heavier coarse particles gradually sink and accumulate at the bottom of the pipeline, while the lighter fine powder suspends in the upper layer and flows. Local accumulation occurs in some areas. As the accumulation hardens and thickens, abnormal stress concentration occurs in the contact area when the spiral blade continuously rubs against the hardened accumulation, which may cause local deformation or even cracking of the blade. The uneven mixing of materials caused by accumulation may also cause fluctuations in the distribution of active ingredients in the finished micro powder, directly affecting the compressive strength and durability when used as a concrete admixture. In view of this, an anti-blocking structure for mineral slag micro powder selecting device is provided. UTILITY MODEL CONTENTS

[0004] The utility model aims at making up for the deficiency of prior art, and provides an anti-blocking structure for mineral slag micro powder selecting device.

[0006] The inner cavity of the feeding pipe and the inner cavity of the feeding assembly are in communication, and the outer wall of the top part of the feeding assembly is designed as a flared opening.

[0007] The outer wall of the horizontal guide rail is located inside one side of the feeding baffle, and the outer wall of the horizontal guide rail is slidably connected with the inside one side of the feeding baffle.

[0008] The half-circular arc surface is arranged on one side of the outer wall of the feeding baffle, and the diameter of the half-circular arc surface is equal to the diameter of the inner wall of the feeding assembly.

[0026] The inclined surface 306 opened on the outer wall of the variable cross-section reinforcing rib 303 continuously scrapes off the coarse particles deposited on the bottom of the pipe during the rotation of the continuous screw conveying blade 302, preventing the accumulation of hardening and hardening, while the synchronous operation of the stirring shaft 304 forces the mixing of the layered material during the conveying process, breaking the distribution isolation of coarse and fine particles, and the structure of the variable cross-section reinforcing rib 303 effectively disperses the local stress generated when the continuous screw conveying blade 302 contacts the accumulated material to the overall structure while improving the structural rigidity of the continuous screw conveying blade 302.

[0027] As shown in Figure 3 The inner cavity of the feeding pipe 1 is in communication with the inner cavity of the feeding assembly 2, and the top outer wall of the feeding assembly 2 is designed as a flared opening.

[0028] After the inner cavity of the feeding pipe 1 is in communication with the inner cavity of the feeding assembly 2, the material can directly fall from the inner wall of the feeding assembly 2 into the inside of the feeding pipe 1.

[0029] As shown in Figures 2-3 The outer wall of the horizontal guide rail 102 is located inside the feeding baffle 101 on one side, and the outer wall of the horizontal guide rail 102 is slidably connected to the inside of the feeding baffle 101 on one side.

[0030] The horizontal guide rail 102 is used to limit the movement track of the feeding baffle 101, so that it can only slide along the outer wall of the horizontal guide rail 102.
