Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a supply / exhaust device for a lower hopper such as a silo that stores powdery particulate matter, or a lower hopper such as an electrostatic precipitator or a bag filter. Is.

[Prior Art] Conventionally, as a supply / exhaust device of this type, as shown in FIG. 4, a large number of blades b are radially attached to a rotary shaft a,
There was a rotor that receives the powdery granular material in the feed chamber c formed between the blades b and supplies or discharges it downward.

In the above conventional apparatus, when handling fine powder or powdery particles having strong adhesiveness, the powdery particles are likely to adhere to the inside of the feed chamber c. Therefore, conventionally, air is jetted into the feed chamber. The powder and granules were blown off, the feed chamber was made shallow, and steel balls and rollers were put in the feed chamber to vibrate and drop the bottom.

[Problems to be Solved by the Invention] However, all of the above-mentioned conventional methods have problems such as an expensive apparatus, a complicated size, and the like.

The present invention has been made to solve the above-mentioned conventional problems, and an object thereof is to provide a powdery / granular substance supply / discharge device which has a simple structure, is hard to be damaged, and is inexpensive and has an excellent supply / discharge effect. To provide.

[Means for Solving the Problems] The powdery / particulate substance supply / discharge device of the present invention is a rotor having a plurality of blades attached to a rotating shaft in a radial direction and forming a feed chamber between the blades. In a supply / exhaust device arranged so as to traverse the flow path of the granular material, a jump rod is accommodated in the feed chamber in a freely movable manner, and a jump rod is prevented from popping out at the outer end of the blade. The invention is characterized in that a fence is attached, and that a square bar or angle steel is used as the jump bar.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1 and FIG. 2, reference numeral 1 is a flow path (supply passage or discharge path) for the granular material, and a hopper for storing the granular material and an aggregate for accumulating the granular material are provided above this. A hopper etc. are provided.

Reference numeral 2 denotes a rotating shaft, which is provided so as to cross the downflow passage 1.

A plurality of blades 5 are radially attached to the rotary shaft 2 via a support member 3 and a bottom cylinder 4, and a feed chamber 6 is formed between the blades 5.

As is clear from FIG. 3, a jump rod 7 made of wood or the like is housed in the feed chamber 6 so that it can move freely.

Reference numeral 8 denotes a fence, which is provided in an annular shape so as to penetrate the tip end portion of the blade 5, so that the jump rod 7 does not fly out of the feed chamber 6.

Therefore, when there is no granular material, the jump rod 7 is positioned at the bottom of each feed chamber 6 due to gravity, but when there is an adhesive granular material, as shown in FIG. Then, by the rotation, it jumps out in the granular material in the feed chamber 6. Normally, the rotor speed is 15 to 30 revolutions per minute, so jump rod 7
By the scratching action and the vibration action by the above, even the adhesive powdery particles can be sufficiently prevented from adhering and can be smoothly supplied or discharged. The jump rod 7 may be a square rod or an angle steel.

[Advantages of the Invention] (1) Even an adhesive powder or granular material does not adhere to the blade and fill the feed chamber.

(2) The structure is simple and inexpensive.

(3) No air source for blowing away the powder or granular material, no power source for moving the jumping rod, etc. are required.

(4) The existing device can be easily improved without enlarging the rotor or modifying the downflow path.
