Abstract

An air blast type actuating device comprises a dish-shaped end plate, a piece of ventilated canvas, a pressure plate, a perforated plate and an air blast ring, wherein a companion flange extends out from the outer margin of the dish-shaped end plate and encompasses the dish-shaped end plate, and bolt holes are distributed on the companion flange; a hole is formed in the center of the dish-shaped end plate and used for connecting other elements; the ventilated canvas allows air to pass through so that gases can be jetted into the ventilated canvas to circulate powders; the pressure plate is used for fixing the ventilated canvas and sheathed outside the ventilated canvas; air holes are formed all over on the perforated plate which is used for supporting the ventilate canvas; a plurality of air blast holes are formed on the inner side of the air blast ring and used for jetting out gases; and an air pipe extends out from the air blast ring to the outside of the dish-shaped end-plate for allowing air entering the air blast ring. The ventilated canvas can actuate powders to flow following the flowing of the air and can isolate powders so that the powders have little possibility to block the outlet of an adapting pipe.

Description

Jet-propelled actuation gear

Technical field

The utility model is relevant for a kind of powder bridge formation breaking plant, especially a kind of jet-propelled actuation gear.

Background technology

In the prior art, for solving the powder bridge formation breaking plant of powder discharging opening place arch formation, the vibrations funnel is set up in its exit at powder, vibrating motor or with a plurality of single-point blowning installations, powder is shaken off in the vibration that the vibrations funnel is to use vibrating motor to produce, but because funnel structure can't effectively seal, so the powder situation produces to use a period of time to have Lou, vibrating motor is connected in motor on the sump walls, the oscillation force that is produced is conveyed to powder by sump walls and then powder is shaken off, the single-point type blowning installation is to bore many apertures on sump walls, installing air blowing plate or air blowing rubber ring, this kind device can't destroy the powder arch formation efficiently, more can will install destruction because of the wear characteristic of powder institute tool, above-mentioned device all can't solve build bridge problem in storage tank of powder effectively.

In the above-mentioned prior art,, and be accumulated to this outlet, cause this exit to be blocked, if can provide a kind of and powder can't be piled up and then continue to fall to outlet, just can save cost and increase the benefit easily because powder proportion and granule size differ.

The utility model content

So the purpose of this utility model is the problem that solves on the above-mentioned prior art, the utility model is for proposing a kind of jet-propelled actuation gear, when the powder of can improveing is over fallen outlet, because the situation that powder proportion and granule size differ is easily in the outlet blocking problem, therefore can make the diffusion of powder by this ventilative canvas in the utility model via air, send out air forth, and should can completely cut off powder by ventilative canvas, make powder because air produces flowing power, be not easy to be blocked in the exit of this adapting pipe.

For proposing a kind of jet-propelled actuation gear in the utility model that achieves the above object, comprise: a ware type end plate, the outer rim of this ware type end plate is extended a faying flange around this ware type end plate, lay bolt hole on this faying flange, there is a hole that is used to connect other elements in the centre of this ware type end plate; The ventilative canvas that can allow air pass through; A pressing plate, this pressing plate are sheathed on outside this ventilative canvas, with the fixing canvas of should breathing freely of this pressing plate; A breaker plate that is used to support this ventilative canvas is laid several pores on this breaker plate; A jet ring, this jet ring is inboard to be provided with the fumarole that several are used to eject gas, and this jet ring protrudes out a tracheae to this ware type end plate, and air enters this jet ring by this tracheae, and ejection enters this ventilative canvas in the fumarole again; And an adapting pipe that is used to accept the powder that falls, this adapting pipe are a ring-like body, and the upper end of this adapting pipe connects the hole of this ware type end plate; Wherein, this pressing plate canvas of should breathing freely presses solidly in this breaker plate, and the outer peripheral edges of this breaker plate are fixedly connected on this ware type end plate.

This ware type end plate is the housing that the longitudinal cross-section is half arc.

The longitudinal cross-section of this ware type end plate is that the housing of half arc has upper end radius of curvature R 1 and bottom curvature radius R 2, and radius R 2 is 10 times of radius R 1.

This pressing plate is by three annulus from large to small, and arrangement is in regular turn from top to bottom formed, and all is provided with several link spans between per two rings, wherein is laid with several bolts hole on the plane of this three annulus.

This breaker plate is sheathed under this ventilative canvas, bores on the breaker plate to be clouded on the plate with numerous punchings, fixes the position of this ventilative canvas with this breaker plate.

This breaker plate is to be fixedly welded on ware type end plate full week.

The beneficial effects of the utility model are: be mainly in the utility model when the improvement past, powder was fallen outlet, because the situation that powder proportion and granule size differ, stop up in outlet easily, therefore can make powder flowing by this ventilative canvas in the utility model via air, make powder produce flowing power, and should can completely cut off powder by ventilative canvas, be not easy to be blocked in the exit of this adapting pipe.

Can further understand feature of the present utility model and advantage thereof by explanation hereinafter, during reading and please refer to accompanying drawing.
