Description
Technical field:
The utility model relates to a kind of vacuum sealing device of powdery solid material.
Background technique:
Powder is the general name of powdery solid, and the production of powder, processing almost relate to all weight industry.In its production and application process, the sealing of powder is an important step, on high poison, inflammable and explosive powder, prevents that effectively powder from revealing is the major issue of closing mutually responsible, safety, occupational health especially.At powder manufacturing, the processing link of malleation than big or vacuum state; Reach leak free requirement; Adopt conventional fluid seal apparatus:, all, can only adopt blind plate sealing at present because sizing can't be cleared up etc. former thereby can not use continuously such as various valves; Want the manual teardown bolt to realize opening or closing, the amount of labour is big and have a potential safety hazard.
Summary of the invention:
The utility model is the deficiency to existing technology, and provides a kind of sealing reliable, reaches the powder seal arrangement that leak " 0 ".
For solving the problems of the technologies described above; The utility model adopts following technological scheme: a kind of vacuum powder seal arrangement, and comprise valve body, be arranged on sealing mechanism, driving mechanism that is connected with sealing mechanism in the valve body and the actuator that is connected with driving mechanism, described valve body comprises material feeding mouth and discharge port; Described sealing mechanism is arranged on material feeding mouth the inner; Described sealing mechanism comprises valve plate and is arranged on the soft lower sealing surface on the valve plate, in described material feeding mouth the inner sealing surface is set, described go up sealing surface be the hard sealing surface and with the surface of contact of lower sealing surface be arc shaped surface; Described driving mechanism comprises transmission shaft and the linkage mechanism that is connected with transmission shaft; Offer semi-spherical grooves in described valve plate lower end, the end of described linkage mechanism is a hemisphere face, and this hemisphere face is positioned at described semi-spherical grooves.
On described valve body, also offer and observe hold concurrently clean-up port and access hole.
Described discharge port bore is greater than the material feeding mouth bore.
Compared with prior art, the utility model has following advantage:
1, sealing surface hard arc is to soft plane, and when compressing, at first two sealing surfaces touch the face contact from line, can press tightlyer; Curved working face can avoid material to adhere to, the sealing safety and reliability; Simultaneously adopt being connected of hemisphere type groove and hemisphere face between valve plate and the connecting rod machine, make valve plate when sealing, the orthofunction of suffering from one's own actions is arranged under external force, the realization reliable sealing.
2, material channel is unimpeded, exports greater than import non-obstruction phenomenon.
3, on the sealing surface lower body fast perforate is set, conveniently observes and clear up sealing surface at any time.
4, the utility model uses rotary cylinder and linkage mechanism, and the reduction means volume is practiced thrift cost.
5, the utility model is particularly suitable for using on the vacuum equipment, and the suction that vacuum produces makes sealing more reliable.

Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated:
Like Fig. 1, shown in Figure 2, the utility model seal arrangement mainly is made up of valve body 1, sealing mechanism 2, driving mechanism 3 and actuator 4.
1, on valve body 1, is provided with: import and export standard flange 101,102; Quick open type is set observes hold concurrently clean-up port 103 and access hole 104, be connected on the valve body through bolt; Two pairs of openings that transmission shaft is installed are set; For the assurance material is unimpeded, no jam phenomenon, discharge port is than the big specification of material feeding mouth.
2, sealing mechanism 2 is made up of valve plate 201, upper-lower seal face 202,203; Lower sealing surface 202 is soft high-abrasive material; Lining is on valve plate 201, and last sealing surface 203 is set on the valve seat 1 and camber for the hard wear-resistant material interference fit, forms sealed working face; Referring to Fig. 3, soft and hard is comparatively speaking.Boss is set at the valve plate back side and establishes a hemisphere type groove 204, be used to connect the bar linkage structure of driving mechanism at the center.
3, driving mechanism 3 is made up of transmission shaft 301, linkage mechanism 302, and connecting rod one end is established axle sleeve and is fixed on the transmission shaft, and is by bolt, detachable; The other end is established hemisphere face 303 and hemisphere type groove 204 Spielpassung, sees through active flange 205 and is fixed on the valve plate 201, referring to Fig. 4.Transmission shaft is connected with actuator, and is connected on the valve body through bearing support 6, and it is free to rotate that axle is provided with bearing, and axle two ends motive sealing realizes sealing by stuffing box 5.
4, actuator 4 is the single-acting rotary cylinder, also can be made as manual or electronic.
This device working procedure is described below: link to each other with equipment or pipeline through flange 101/102, cylinder moves by electromagnetic valve; Rotary cylinder work: drive transmission shaft, connecting rod, lower seal rotate jointly, realize that this mechanism closes or opens, and the opening state schematic representation is seen Fig. 5 and Fig. 6.During work, the output torque of cylinder changes into the sealing surface pretightening force through linkage mechanism, realizes reliable sealing; Can check the sealing situation at any time through observing the clean-up port 103 of holding concurrently, guarantee the operation of this safe and stable arrangement.
