Dust removal adsorption type building block wall surface grinding device based on Bernoulli's law

Abstract

The invention discloses a dust removal adsorption type building block wall surface grinding device based on the Bernoulli's law. The dust removal adsorption type building block wall surface grinding device comprises a Bernoulli's type centripetal rotation dust collection grinding device, a right-angle side grinding device, a dust prevention and noise reduction partition device and a five-axis mechanical arm moving vehicle. The invention belongs to the technical field of concrete inner wall building block grinding devices, and particularly relates to the dust removal adsorption type building block wall surface grinding device based on the Bernoulli's law. Centripetal acting force generated in the rotating process, the Bernoulli's law and the law that the air flow direction is changed due to the pressure intensity change in the environment are creatively combined, and limiting of grinding dust in an arc-shaped grinding tool is effectively achieved; meanwhile, a dust collection glue connecting plate on a wing-like arc-shaped protrusion is matched to achieve adhesion of dust outside the arc-shaped grinding tool, and the multi-angle and multi-direction dust removal function during building block surface grinding is effectively achieved; and in order to reduce noise and prevent the grinding dust from entering a noise reduction groove hole, an anti-deposition flow guide opening is in tangent connection with a noise reduction circular groove, dust accumulation is avoided, and the noise reduction effect is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of building block grinding devices, in particular to a dust removal and adsorption block wall grinding device based on Bernoulli's law. Background technique [0002] Blocks are man-made blocks made of concrete, industrial waste (slag, fly ash, etc.) or local materials. requirements for institutional reform. [0003] Prefabricated building refers to the transfer of a large number of on-site operations in the traditional construction method to the factory, where the building components and accessories (such as floors, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory, and transported to the construction site. Reliable connections are assembled and installed on site. [0004] During the installation process of block building, it is necessary to connect multiple groups of assembled blocks to each other, and to ensure the adhesion effect between assembled blocks through cement ...

Problems solved by technology

[0005] In view of the above situation, in order to overcome the defects of the prior art, the dust removal adsorption block wall grinding device based on Bernoulli's law provided by the present invention, in order to solve the dust splashing in the grinding process, and the conventional grinding equipment is As a whole, once the grinding surface is not smooth enough, one end of the grinding equipment will be tilted, and the other end will have too much contact with the material to be ground, which will affect the grinding effect. The invention creatively uses the centripetal effect generated during the rotation Combining force, Bernoulli's law and the change of air flow direction caused by changes in environmental pressure, a group of grinding tools using the combination principle is constructed. Multiple groups of tools are independent of each other and play the same role, avoiding the Unbalance affects the grinding effect. By increasing the curvature of the grinding tool surface, the wind speed on the upper surface increases and the air pressure decreases during the rotation process, which makes the external dust of the grinding tool contact and adhere to the dust-collecting adhesive plate, increasing the In order to give the curvature of the arc groove for centripetal force dust collection, the dust is always subject to the centripetal force provided by the inner arc groove for the centripetal force dust collection arc groove during the rotation of the grinding tool. The centripetal force dust collection arc groove, combined with negative pressure dust collection equipment, can effectively collect dust and finally realize the function of reducing dust splash; since the front end of the grinding tool is a tip, in order to avoid the force point of the tip during the rotation of the grinding tool It is small and bears high pressure. By changing the bending direction of the front end of the grinding tool, a set of drag-reducing reverse bending tips with increased stress area is constructed to reduce the wear probability of the grinding tool; in order to reduce noise while To prevent the grinding dust from entering the noise-reducing slot, connect the anti-sedimentation diversion port with the sound-absorbing circular slot tangentially to avoid dust accumulation and ensure the noise reduction effect; in order to realize the cleaning work of the corner before the building block and the building wall, the Straight edge grinding The straight edge grinding tooth saw in the rectangular cover plate is combined with the crank connecting rod and applied in the present invention, which realizes the function that the traditional circular grinding tool cannot grind the wall corner, and effectively solves the problem that the existing During the grinding process of the building block grinding device, the dust splashes, the noise is loud, and the corners are difficult to clean
