Device for removing redundant gypsum on surface of building material

Abstract

The invention discloses a device for removing redundant gypsum on the surface of building materials, which comprises a machine case, a heat dissipation box, an operating table, a bottom box, a placement tank, a heat dissipation fan, a ventilation pipe, a sandblasting device, a storage box, a sliding rod, a spray groove, a conduit, and a booster. Pressure pumps, hot air blowers, air ducts, ducts, mixing boxes, spray pipes, nozzles and slide balls. The beneficial effects of the present invention are: by installing the storage box at the bottom of the cabinet, coarse sand is stored inside the storage box, and the storage box is connected with a sandblasting device, and the coarse sand inside the storage box is sprayed out by the sandblasting device, and the coarse sand and the added The compressed air flow is sprayed together to remove excess gypsum on the surface of building materials, thereby increasing the removal effect. The sandblasting device uses a hot air blower to provide sandblasting airflow, and a booster pump is installed inside the sandblasting device, which can not only increase the air flow rate, but also dry the coarse sand, so as to avoid the wet coarse sand from making the building The gypsum on the surface of the material is wetted and cannot fall off.

Description

technical field [0001] The invention relates to a device for removing redundant gypsum on the surface of building materials, which belongs to the field of building plate processing. Background technique [0002] There are many kinds of building materials, the most representative of which are building panels, building panels and panels used in building decoration. Building panels are usually made into flat rectangular shapes of standard sizes as components of walls, ceilings or floors. It also mostly refers to metal plates formed by forging, rolling or casting. Building plates are divided into thin plates, medium plates, thick plates, and extra-thick plates according to their own thickness. Building boards need to go through a series of processing steps before they are put into use, including the removal of excess gypsum on the surface of building materials, which requires the use of removal devices. [0003] However, existing devices for removing excess gypsum on the surfac...

Problems solved by technology

[0003] However, existing devices for removing excess gypsum on the surface of building materials still have certain defects in use. Because the existing devices generally use coarse sand spraying on the surface of building materials to remove the gypsum layer by spraying, if moisture remains in the coarse sand, Not only will it not increase the removal effect, but it will leave the coarse sand on the surface of the gypsum layer, making it more difficult to remove the excess gypsum, and the internal pipes of the device are extremely easy to be blocked due to the need to spray coarse sand
