Abstract
The utility model discloses a rotatory discharge valve, comprising a valve body and a rotor which is hollow and driven by power to rotate within the valve body; a rotor shaft is arranged fixedly on the end surface of the rotor; a feeding hole and a discharge hole are arranged on the valve body; an end cap is arranged on both ends of the valve body; the inner hollow space of the rotor is divided into two chambers by a clapboard; each of the chamber is provided with an opening; the two openings are corresponding respectively with the feeding hole and the discharge hole of the valve body; the two openings always make the feeding hole and the discharge hole not intercommunicated during the rotation of the rotor. For the rotatory discharge valve, the feeding and the discharge are synchronous so as to improve the rotational speed of the rotor; the two feeding processes are finished when the rotor rotates one circle every time, thereby having the advantages of short feeding slot time, high efficiency, stable and even discharge, clearness and thoroughness. The rotatory discharge valve can be used in an air delivery device or a vacuum dryer for powder particle material; thereby the discharge operation can be performed quickly and continuously; gas and solid in the system can be kept stable; and the air pressure in the upper feed bin and the lower feed bin of the discharge valve also can be cut off at the same time, which plays a role in sealing.
Description
Technical field
The utility model relates to a kind of rotary unloading valve.
Background technique
The rotary unloading valve is a kind of in industry production such as grain, metallurgy and chemical industry, in order to powder, pellet, powder mixture are transported to the device of subordinate's feed bin from higher level's feed bin; The rotary unloading valve also claims rotary valve, rotary feeder, rotary Valve Feeder, lock gas feeding machine, rotation blow-off valve etc., no matter title how, its working principle all is identical, all is to utilize the rotation of rotor to finish discharge, the blanking process of powder material.Chinese patent ZL02279489.1 discloses a kind of name and has been called the product that rotates blow-off valve, this valve is provided with upper and lower opening on the cylndrical surface of a cylindrical valve casing, concentric is installed the inner rotary body of a cylindrical shell shape in the valve casing, both ends of the surface at inner rotary body are provided with running shaft, and an opening is also arranged on the cylinder of inner rotary body; The valve casing opening is provided with adpting flange, and end cap is equipped with at the valve casing two ends.This rotation blow-off valve is when work, and along with the rotation of inner rotary body in valve casing, the powder material enters inner rotary body from the opening of valve casing one end off and on, and discharges from the opening of the valve casing the other end, and charging and discharging hocket; Because have only an opening on the inner rotary body of this valve, inner rotary body whenever turns around, and can only finish a feeding process, so the feeding intermittent time is long, inefficiency also is easy to generate material and discharges halfway phenomenon.
The model utility content
The purpose of this utility model provides the rotary unloading valve of a kind of feeding intermittent time weak point, high working efficiency.
For achieving the above object, the utility model adopts following technological scheme: a kind of rotary unloading valve, comprise valve body and can in valve body, rotate by motivational drive, inside is the rotor of cavity, rotor end-face is installed with rotating shaft, one material feeding mouth and a discharge port are arranged on the valve body, there is end cap at the valve body two ends, rotor cavity is divided into two chambers by a dividing plate, each chamber has an opening, two openings are corresponding with the charging and discharging mouth of valve body respectively, and two openings remain material feeding mouth and are not communicated with discharge port in the rotary course of rotor;
On the rotor two openings of sizes equate, symmetry and establishing, on rotor cross-section, the pairing central angle of each opening is less than 90 °; Charging and discharging mouth on valve body symmetry and establishing, valve body charging and discharging mouth equates with epitrochanterian openings of sizes with the size of body cavity intersection;
Described dividing plate is a flat board by the rotor spin axis;
The residing plane parallel of described dividing plate and rotor openings;
The outer rim of two ends of rotor face all outwards turnover form outer turning edge, correspondingly, the valve body two ends be equipped with endoporus with outside the end face flange that turns edge and be sealed and matched, described end cap is connected with the end face flange seal;
At the power intake of rotating shaft, next-door neighbour's end cap is provided with dynamic sealing means.
The utility model utilizes a dividing plate that the chamber of internal rotor is divided into two, it is corresponding with the charging and discharging mouth of valve body respectively to be equipped with two openings again, charging and discharging just can be carried out synchronously like this, rotor speed is improved, under the constant situation of feed flow, rotor whenever rotates a circle and has just finished two feeding processes, short, high working efficiency of feeding intermittent time, simultaneously, discharge is stable, even, thoroughly clean.This valve two ends utilize that rotor end-face turns edge outward, valve body end face flange and end bracket enclosed, and are simple in structure, sealing effect is good, be convenient to make install, and in use fault is few maintenance for ease of maintenaince; The tightness that dynamic sealing means can further improve this valve is set.
Charging and discharging mouth at conveying of powder material strength or Minton dryer uses such valve, can in extremely rapid succession carry out the discharge operation, guarantee gas, Pickering in strength conveying, the vacuum drying system, the air pressure of the upper and lower level feed bin of laying-off valve can be cut off again simultaneously, play seal action.The utility model is widely used in the discharge operation of various powder grain materials, and especially effect is more obvious on the conveying of grain strength, grains vacuum drying machine.
