Abstract

The utility model discloses a control gate used for the package and the measurement of powder material. An upper pipe clamping roller and a lower pipe clamping roller are arranged on the upper side and the lower side of an ash discharge soft pipe. A center axle is connected with a tight expansion axle by a connection board and is positioned between an upper sliding block and a lower sliding block. The center axle is movably connected with an electromagnet pull rod by a connection rod. The upper sliding block and the lower pipe clamping roller are respectively fixed on a guiding axle. The upper sliding block and the upper pipe clamping roller are connected by a connection block and are arranged on the guiding axle by the connection block. The ash discharge soft pipe is tightly clamped without ash discharge by the relative movement of the upper pipe clamping roller and the lower pipe clamping roller to repeatedly play the function of controlling the gate in circulation. The utility model has the advantages of tight gate closing, uneasy ash leakage, little pollution, raw material saving, long service life, etc.

Description

Controlling valve

The utility model relates to a kind of control door of powder package metro-measuring, belongs to the start-stop system of conveying powdered thing in the packaging facilities.

The gate of existing powder package metro-measuring, particularly cement-packing plant has transverse metal flashboard and vertical vertical steel disc flashboard, these two kinds of flashboards all have the flashboard box, movable flashboard slideway freely, all be to utilize the ash hole size design to go out to be a bit larger tham the flashboard of ash hole, when snap action, finish keying, with the control ash discharge.Above-mentioned flashboard acts frequently, and abrasion factor is high, and after the flashboard wearing and tearing, the gap is strengthened between flashboard and the flashboard box, causes Lou ash, increases packing shop and pollutes.And can cause the card flashboard during inadequately with granule as cement fineness.Because flashboard acts frequently, will wear into deep trouth to flashboard for one or two class when serious, just need to change flashboard, influence is produced.

The purpose of this utility model is to overcome the weak point in the background technology and a kind of no flashboard wear phenomenon is provided, leakiness ash not, pollute little, the control door of long service life.

The purpose of this utility model is achieved in that card pipe roller is positioned at ash discharge flexible pipe both sides up and down up and down, tween drive shaft is connected with tension shaft by connecting panel, it is up and down between the slide block, tween drive shaft flexibly connects by connecting rod and electromagnet pull bar, top shoe is fixed on the axis of guide one end, following card pipe roller is fixed on the other end of the axis of guide, and sliding block is connected by the connection piece with last card pipe roller, and packaged on the axis of guide by connection.

The utility model can also be realized by following measure: inhibiting device is equipped with at axis of guide two ends respectively.Upper and lower card pipe roller is to add the steel axle in the India rubber tube to make.

The utility model is compared background technology and is had following advantage:

1, because the utility model has removed traditional metal flashboard, thereby do not exist flashboard to wear and tear, often change flashboard and leakage ash fouling phenomenon, its closing gate is tight, pollutes little;

2, save material long service life.

Description of drawings is as follows:

Accompanying drawing is the utility model structural representation.

Among the figure: electromagnet (1), top shoe (2), pull bar (3), tension shaft (4), connecting rod (5), ash discharge flexible pipe (6), jackscrew (7), the axis of guide (8), inhibiting device (9), following card are managed roller (10), are gone up to block and manage roller (11), sliding block (12), connection piece (13), tween drive shaft (14), jackscrew (15).

Embodiment describes the utility model in detail below in conjunction with (accompanying drawing): go up card pipe roller (11) and be positioned at ash discharge flexible pipe (6) upside, following card pipe roller (10) is positioned at the downside of ash discharge flexible rubber hose (6), tween drive shaft (14) is connected with tension shaft (4) by connecting panel (16), tween drive shaft (14) is by connecting rod (5) and pull bar (3), electromagnet (1) connects, pull bar (3) is hinge joint with connecting rod (5), top shoe (2) is fixed on an end of the axis of guide (8) by jackscrew (15), following card pipe roller (10) is fixed on the axis of guide (8) other end by jackscrew (7), the axis of guide (8) two ends are respectively equipped with inhibiting device (9), distance between the inhibiting device is according to the diameter of ash discharge flexible pipe (6) and card pipe roller miles of relative movement and decide, last card pipe roller (11), sliding block (12) is connected by connection piece (13), and is contained on the axis of guide (8) by connection piece (13).Card pipe roller (11,10) is made with adding the steel axle in the India rubber tube up and down.Use the utility model ash hole to change flexible rubber hose into, whole parts place in the iron-clad (accompanying drawing does not draw).

Principle of work of the present utility model: when propulsion source electromagnet (1) adhesive, carry on pull bar (3) drivening rod (5), drive tween drive shaft (14) and rotate an angle, tension shaft (4) follows by action, make on the top shoe (2) and carry, sliding block (12) presses down, top shoe is carried on (2), the following card pipe roller (10) that is fixed on the axis of guide (8) is followed to be carried, pressing down of sliding block (12) forces card pipe roller (11) descending, up and down card pipe roller (11, relatively moving 10) is when moving to ash hole flexible pipe (6) central authorities, the ash hole flexible pipe is stuck, and promptly stops ash discharge.When electromagnet (1) cuts off the power supply not adhesive, following card pipe roller (10) is by electromagnet (1) and the automatic downslide return of the axis of guide (8) deadweight, last card pipe roller (11) is retracted the position by the sebific duct tension on automatically, thereby drives top shoe (2), sliding block (12) and go up card pipe roller (11) return.Above-mentioned going round and beginning again finished the effect of control door.

Claims

1, a kind of control door, comprise electromagnet, pull bar, connecting rod, it is characterized in that: card pipe roller is positioned at ash discharge flexible pipe both sides up and down up and down, tween drive shaft is connected with tension shaft by connecting panel, and between slide block up and down, tween drive shaft is by connecting rod and the flexible connection of electromagnet pull bar, top shoe is fixed on the axis of guide one end, following card pipe roller is fixed on the other end of the axis of guide, and sliding block is connected by the connection piece with last card pipe roller, and packaged on the axis of guide by connection.
