Abstract

The utility model relates to a baffle-regulation type static separator of vertical middle-speed roller type milling machine. A baffle for regulating separation fineness has only a shaft extending out of a separator to facilitate sealing; the baffle can be regulated in the range of a wide angle close to 180 degrees, and can make airflow rotate reversely; consequently, the utility model can regulate the separation fineness within a large range. An in-built power-returning gas-locking device has small structural shape size, and can be inserted into the press frame of the milling machine to reduce the height of the milling machine, thereby reducing the height of plant and feed; therefore, the power-returning gas-locking device has the advantages of simple and flexible structure, and tight gas-locking. The utility model is equipped with a secondary air duct, so the efficiency of a separator is increased after secondary separation. In the middle-speed milling machine, the sealed wind can be used as secondary wind source.

Description

The static separator of a kind of vertical middling speed ring-roller mill controllable register formula

The utility model belongs to vertical middling speed ring-roller mill field, relates in particular to the static separator of a kind of vertical middling speed ring-roller mill controllable register formula.

At present, the common static separator of controllable register formula that on vertical middling speed ring-roller mill, adopts, at first all baffle plates of the separation of the adjusting on its separator fineness all rotate with turning cylinder, and turning cylinder all stretches out outside the separator, so just influenced the sealing of separator, about 70 degree of the angle of baffle plate rotation have simultaneously influenced the adjustable range of separating fineness; Secondly, returning the powder flapper is outlet structure, because outlet structure appearance and size is big, therefore causes the increase of factory building and feed level, and in addition, separator has only a separation process, and the efficient of separator is not high.

The purpose of this utility model provides a kind of good airproof performance, and the adjustable range of separating fineness is wide, simple in structure, the static separator of a kind of vertical middling speed ring-roller mill controllable register formula that separative efficiency is high.

The technical solution of the utility model is: the static separator of vertical middling speed ring-roller mill controllable register formula, comprise coal spout, separator shell, the separator inner cone, the baffle plate governor motion, the separator top board, it is characterized in that: (1) baffle plate governor motion is arranged on separator inside, have only a controllable register to be connected with turning cylinder, the axle of all the other baffle plates is fixed on Outer Taper top board and the inner cone, baffle plate can sway, all be welded with crank on the baffle plate, two holes are arranged on each crank, connect into a week with connecting rod between the hole of crank, stretch out in the rotating shaft of active baffle plate on the spindle nose of separator and install operator; (2) between inner cone and coal spout bottom flapper is set, by the inner cone lower port diameter one cylinder is set, the cylinder bottom has several rectangle breach, but the baffle plate of reaction is set on the breach, constitutes the circumscribed polygon of blanking barrel when baffle plate stirs maximum position; (3) be provided with secondary air channel in the middle and lower part of separator inner cone, the airduct inboard has the aperture of week spray wind, and airduct has a short circular cone to be welded on the inner cone on the top, guides to the separator outside by an airduct, and the baffle plate of regulating air quantity externally is set.

The utility model has the advantages that: regulating the baffle plate that separates fineness only has a shaft extension to go out outside the separator, is convenient to sealing, and baffle plate can be adjusted in polarizers of big angle scope, near 180 degree, and can make the air-flow opposite spin, therefore, can regulate on a large scale and separate fineness; Built-in time powder flapper construction profile size is little, thereby can insert in the pressure frame of grinding machine, reduces the grinding machine height, thereby reduces factory building and feed level, and is simple in structure, flexible, lock gas is tight; Owing to secondary air channel is set,, improves the efficient of separator by secondary separation.In the middling speed grinding machine, can be with sealing wind as the secondary wind regime.

Below in conjunction with drawings and Examples the utility model is described further.

Fig. 1 is the structural representation of the built-in baffle plate governor motion of separator;

Fig. 2 is the connection diagram of the built-in baffle plate governor motion of separator baffle plate;

Fig. 3 is the structural representation of the built-in flapper of separator;

Fig. 4 is the structural representation of the secondary winding-up separator of separator.

Among Fig. 1, the baffle plate governor motion is arranged on separator inside, has only a controllable register 1 to be connected with turning cylinder 2, and the axle of all the other baffle plates is fixed on Outer Taper top board 3 and the inner cone 4, baffle plate 1 can rotate around axle 2, all be welded with crank 5 on the baffle plate, two holes are arranged on each crank, connect into a week with connecting rod 6 between the hole of crank, stretch out installing operator 7 on the spindle nose of separator in the rotating shaft of active baffle plate, 8 is separator shell, and 9 is gear, and 10 is the corner indicating device.

Among Fig. 2, connect into a week 8 with connecting rod 6 between the hole of all baffle plate cranks 5.

Among Fig. 3, between separator inner cone 4 and coal spout 12 bottoms, flapper is set, by the inner cone lower port diameter one cylinder is set, the cylinder bottom has several rectangle breach, but the baffle plate 13 of reaction is set on the breach, constitute the circumscribed polygon of blanking barrel when baffle plate stirs maximum position, 14 is the baffle plate rotating shaft.

Among Fig. 4, be provided with secondary air channel 15 in the middle and lower part of separator inner cone 4, the airduct inboard has the aperture 16 of week spray wind, airduct has a short circular cone to be welded on the inner cone 4 on the top, guide to the separator outside by an

airduct

17,8 is separator shell, and the baffle plate of regulating air quantity externally is set.
