Abstract
The utility model relates to a flexible sealed air-locking rotary valve for feeding used for a pressure gas ducting device for the quantitative feeding of powdered materials, which is composed of a valve body and a rotor which is arranged in a valve cavity. The utility model is mainly characterized in that the inner wall of the valve body is provided with a bush, the peripheral rim of the rotor is provided with a groove, and flexible sealed pieces are embedded between the groove; the peripheral wall of the valve body is provided with the powdered materials inlet, a powdered materials outlet and an extract opening which are arrayed in a non-equidistant order mode; both ends of the rotor is embedded with pressure resistant and wear resistant sealed pieces. The utility model has the advantages of novel design, simple structure, and low device cost, and the utility model can effectively prevent scratching and blocking, and can guarantee the long-period operation of production.
Description
The utility model relates to a kind of flexible sealing feeding lock cyclone rotary valve that is used for the pressed gas pipeline transporter of powder weight feed.
At present, general manufacture of cement factory, the fuel coal dust could be entered in the kiln by the higher pipeline of input pressure by the charging air-lock device by the weight feed machine, the rotor and the valve housing inwall of rotation star valve are contactless in its charging air-lock device, there is certain clearance to exist, easily influence the stability of pressure, so on adopting, connect the storehouse of bleeding between the following valve and carry out voltage stabilizing, pressure regulation, increased cost of equipment, again because of being entrained with a spot of hard assorted particle in the coal dust, in the gap that will snap into rotor and inner walls unavoidably in service, produce and scratch and stuck phenomenon, influenced and produced normal operation.
The purpose of this utility model is the weak point that exists at prior art and a kind of improved flexible sealing feeding lock cyclone rotary valve is provided, it is simple in structure, reduce equipment manufacturing cost, prevented to scratch valve interior wall and stuck rotor again effectively, guaranteed to produce long-term operation.
The purpose of this utility model is achieved in that a kind of flexible sealing feeding lock cyclone rotary valve.It is made of valve body and the endoceliac rotor of valve, and it mainly is that lining is arranged on the valve interior wall, and rotor week is embedded with flexible seals along being provided with groove between groove.With lining contact seal, the valve body perisporium is provided with not equidistant tactic powder import, powder outlet and bleeding point, and two ends of rotor axially is embedded with withstand voltage abrasive resistance sealing parts.During work, the powder of being sent here by the supply machine enters from the valve body import, filling is in rotor, along with rotor is done the clockwise direction rotation, powder in the rotor enters in the closed area of forming with housing, then powder is brought into outlet and is discharged, and intercepts because of sealing member is arranged between groove, the high pressure gas of outlet area can't be to the importer to leakage, so entrance region air pressure can not produce obvious fluctuation.After the powder in the rotor is poured out by outlet, the high pressure gas of outlet area will be filled in the rotor dead slot, and along with the rotation of rotor, the high pressure gas in the groove enter bleeding point, enter the negative pressure dust collecting system, make in the rotor to continue charging near returning import behind the normal pressure.Simultaneously, carry out between hoop sealing and rotor end-face and the big valve gap Inflatable balance and flushing and protect and expand because of two ends of rotor axially is embedded with sealing member, prevented powder from axle journal flow out and the outlet area high pressure gas by end face to the entrance region crossfire.
The utility model modern design, simple in structure, reduced equipment manufacturing cost, reduced scuffing and stuck phenomenon, guaranteed production run, have practical value.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model front view.
Fig. 2 is I-I cutaway view of Fig. 1.
Shown in Fig. 1-2, a kind of flexible sealing feeding lock cyclone rotary valve, it is made of the rotor (3) in valve body (1) and valve body (1) chamber, on its valve body (1) inwall lining (2) is arranged, rotor (3) week is embedded with flexible seals (5), with lining (2) contact seal along being provided with groove (4) between groove (4), valve body (1) perisporium is provided with not equidistant tactic powder import (6), powder outlet (7) and bleeding point (8), and rotor (3) two end axles is to being embedded with withstand voltage abrasive resistance sealing parts (9).
