加圧ホツパー内の空気圧力を例えば0.5〜１Kg／
cm2に加圧する必要がある。 For example, in a sand blasting molding device for casting, sand in a pressurized hopper is supplied to a continuous mixer through a gate, and the sand mixed in the continuous mixer is blasted through a blasting molding nozzle and a rubber hose.
Prior to the start of the mixing and spraying operation, in order to steadily supply the sand in the pressure hopper to the continuous mixer,
The air pressure in the pressure hopper is set to, for example, 0.5 to 1 kg/
It is necessary to pressurize it to 2 cm.

ように、流出して了う。 However, as shown in the vertical cross-sectional view of FIG. 1, the conventionally used arm gate has a cylindrical gate case 022 having an arcuate lower opening edge and the opening end of the gate case 022 is closed with an appropriate clearance. It consists of an arc-shaped gate sheet 024 which is pivotally attached to the center 0 of the lower arc-shaped opening edge of the gate case 022 by a gate arm 024', so when the pressure hopper 01 is pressurized to, for example, 0.5 to 1 Kg/cm 2 , the gate case Some of the sand S in 022 is gate sheet 0
It flows out through the clearance between 24 and 24 as shown by the arrow.
上記クリアランスを零として、ゲートシート０
２４でゲートケース０２２の下端開口を密閉して

ばらつきを生ずる。 Assuming the above clearance to be 0, the gate seat is 0.
It is not impossible to prevent the leakage of sand by sealing the lower end opening of the gate case 022 with 24, but if it is sealed, it is necessary to supply air to the continuous mixer side as well. It becomes difficult to adjust the pressure between the pressurized hopper side and the continuous mixer side, and air no longer flows from the pressurized hopper side to the continuous mixer side, resulting in variations in the amount of sand supplied at the start of kneading by the continuous mixer.
本考案はこのような事情に鑑みて提案されたも

つたことを特徴とする。 This invention was proposed in view of these circumstances, and not only prevents sand from flowing out when the hopper is closed, but also allows air to flow from the pressurized hopper to the continuous mixer to balance the internal pressure of the pressurized hopper and the continuous mixer. The purpose of the present invention is to provide a powder supply device that can stably supply sand by storing powder and granules, and by opening and closing the opening end of a gate case that receives compressed air pressure with a gate sheet. The gate case and/or the gate sheet is provided with a ventilation hole, and the ventilation hole is covered with a porous ventilation member.

ケースである。 Next, to describe the structure of arm gate 2, the third
In the figure, 22 is a gate case vertically protruding from the lower end of the pressure hopper 1 and having a rectangular cross section, and the lower end side edge of the lower opening of the gate case 22 is
It is formed into an arc centered on a point, and a large number of small diameter ventilation holes 23, 23... are bored in its side wall, and a canvas 28 covering the small diameter ventilation holes 23, 23... is attached to the gate case. It is attached to the outer surface of 22. Reference numeral 24 denotes a gate seat made of an arcuate curved plate that faces the arcuate lower edge of the gate case 22 with an appropriate clearance and is rotatably pivoted around the zero point via a fan-shaped arm. A large number of small-diameter ventilation holes 25 are bored in the gate sheet 24, and these small-diameter ventilation holes 25 are covered with a canvas 28 stuck to the lower surface of the gate sheet 24. At the same time, the other end is pivotally connected to an arm member protruding from the door-shaped arm of the gate sheet 24, so that the gate sheet 24 can be moved to zero.
By rotating around the point, arm gate 2
27 is a hydraulic cylinder that opens and closes the gate case 2.
In this case, the pressurized hopper 1 is airtightly connected to the supply port of the continuous mixer 3 by surrounding the hopper 2 and the gate sheet 24.
