A device for removing excess gypsum from the surface of building materials

Abstract

The invention discloses a device for removing excess gypsum on the surface of a building material. The device comprises a chassis, a radiating box, an operation table, a bottom box, a holding groove, a radiating fan, an air exchanging pipe, a sand blasting device, a storage box, a sliding rod, a spray groove, a guide pipe, a booster pump, a hot air blower, an air pipe, a communication pipe, a mixing tank, a spraying pipe, a nozzle and a sliding bead. The device has the beneficial effects that the storage box is mounted at the bottom of the chassis and stores coarse sand, the storage box is connected with the sand blasting device, and the sand blasting device sprays the coarse sand inside the storage box; the coarse sand and pressurized airflow are sprayed out together and used for removing the excess gypsum on the surface of the building material, and thus the removal effect is enhanced; the sand blasting device is internally provided with the hot air blower used for providing sand blasting airflow, and the booster pump is arranged inside the sand blasting device so that not only can the airflow flowing speed be increased, but also the coarse sand can be dried; and accordingly the coarse sand is dried, and the situation that the gypsum on the surface of the building material is wetted by wet coarse sand and cannot fall off is avoided.

Description

technical field [0001] The invention relates to a building material surface processing device, in particular to a building material surface excess gypsum removal device, 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 dev...

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
