Abstract

PURPOSE: A device for supplying low viscosity and rapid dryable architectural materials is provided, thereby preventing them from adhering to the inner wall of a supplying hopper. CONSTITUTION: The device for supplying low viscosity and rapid dryable architectural materials consists of a hopper type main body(1), multiple vibrators(2) installed in the outer border of the main body(1) with a regular interval, and operated by a small motor; large and small feeding rollers(3, 4) respectively installed in the front and rear of inner walls(5, 5') of the main body(1) to be rotated in the opposite direction each other; and a quantity-regulating nozzle(7) in the lower part of the hopper.

Description

Supply device of low viscosity and quick dry building material

The present invention is a mixed material containing components such as magnesium oxide, magnesium chloride or activated clay obtained from industrial clay, and industrial salts, which is weak in viscosity and hardened before flowing down due to difficulty in continuous flow or rapid drying. Use of difficult materials to manufacture building interior and exterior materials and artificial marble, or to produce cement moldings with weak viscosity, very similar to the above-mentioned mixed materials, and to facilitate continuous flow before the raw material supplied to the hopper is cured. The present invention relates to a device for supplying low viscosity and quick-drying building material which is made possible to be uniformly and continuously supplied to a transfer conveyor.

Conventionally, boards, sheets or artificial marble for building interior and exterior are made of materials containing magnesium oxide, magnesium chloride, activated clay, and brine, which are difficult to make sheets, boards, and marbles due to rapid drying and weak viscosity. When lowering or manufacturing cement products such as ready-mixed concrete or cement mortar, the material mixture passes smoothly through the hopper and is not supplied smoothly to the conveyor belt, and the flow and fluidity are weak and quick-drying. It was difficult to mold the product because the mixture was stuck and hardened, or the raw material was weakly supplied and was cut in pieces instead of continuously.

The present invention is for the smooth supply of low-viscosity and quick-drying building materials, such as sheets and boards for building interior and exterior materials, boards or artificial marble or raw materials for cement products, which are difficult to supply raw materials due to weak viscosity, fast drying, and low continuous flow. When providing a supply device as described in detail with reference to the accompanying drawings as follows.

1 is a cross-sectional view of a supply apparatus according to the present invention.

1: hopper body 2: vibrator

3: large feeding roller 4: small feeding roller

5,5 ': side wall 6,6': wing

On the upper circumferential surface of the main body of the hopper type feeder 1, a plurality of vibrators 2 operated by a small motor (not shown) are installed at regular intervals, and the upper and lower sides of the hopper type feeder face toward the center of the hopper or toward the hopper wall and are opposite to each other. In the direction of the circumferential surface and symmetrically on the outer circumferential surface thereof, the small feeding rollers 3 and 4 are placed on the front and rear inner walls 5 and 5 'of the feeder body 1. ) Is installed to be rotated in a tangential rotation and the bottom of the hopper is equipped with a fixed-quantity supply nozzle (7) for adjusting the amount of material.

The low-viscosity and quick-drying building material supplying apparatus of the present invention constituted as described above has a low viscosity, which is difficult to continuously supply and quick-drying, and thus is easy to be hardened and adheres to the inner wall of the hopper, such as magnesium oxide and magnesium chloride or activated clay and brine. Raw materials mixed well with cement mortar, ready-mixed concrete, etc., into the supply apparatus main body 1 of the present invention, and kneaded and stirred at the time of manufacturing sheets, boards, and artificial marble or cement products for building interior and exterior. Small and large feeding roller 3 mounted on the upper and lower sides of the main body of the feeder while vibrating the feeder main body 1 by operating the mounted vibrator 2 and having a plurality of vanes 6 and 6 'symmetrically attached to the outer circumferential surface thereof. 4) When the raw material is not attached to the wall of the main body 1, the upper and lower feeding rollers which are stirred by vibration and rotated in opposite directions to each other (3). The blades 6 and 6 'of the 4) guide the raw materials down in a short time while being agitated, so that the raw materials are continuously fed to the conveying conveyor without breaking into fragments. By supplying the material while controlling the supply amount of the raw material to be supplied evenly spread in a controlled amount on the conveying conveyor, if the raw material thus passed through the pressing roller (not shown) sheet, board and artificial Marble or cement products can be obtained with a uniform thickness.

In conclusion, the raw material feeder of the present invention can supply a uniform thickness to the moving conveyor below by vibrating agitation and guide feeding rollers even before drying, even if the fast-drying viscous raw material is low, so that the inner wall of the feeder main body 1 It is effective in preventing the raw material from being attached and cured or being supplied as the raw material is broken into pieces.
