Abstract
The invention discloses a spiral gate. A sealing structure of the spiral gate is that: one sealing packing groove is formed at the same position on the two sides of a flashboard respectively; each sealing packing groove consists of two elongated baffle plates which are vertical to the motion direction of the flashboard; sealing fillers are filled in the sealing packing grooves; the sealing packing grooves are directly contacted with the surface of the flashboard; and the sealing fillers are pressed on the surface of the flashboard through sealing pressing plates. Due to the adoption of the technical scheme, the spiral gate has the advantages that: the compression strength of a sealing element can be adjusted according to the actual using condition, so the adjustment is convenient and simple and the operation is easy; and the contact area of the sealing element and the flashboard is also greatly increased, so the sealing effect is greatly improved and the spiral gate can still work normally under the condition of overlarge pressure of a host machine.
Description
Technical field
The invention belongs to the technical field of material handling machinery, more particularly, the present invention relates to a kind of spiral gate.
Background technique
Spiral gate is used for top, storehouse, bottom of the reservior and the import and export etc. of industries such as building materials, metallurgy, mine, electric power, chemical industry, glass, light industry, grain, is that the control mass flow changes greatly, starts frequently, cuts off equipment rapidly.
Spiral gate mainly is made of parts such as gate support body, flashboard, screw mandrel, nuts, rotates handwheel with hand and makes the screw mandrel band feed screw nut and the to-and-fro motion of flashboard along continuous straight runs, reaches the keying purpose of gate.Its mode of operation is: rotate handwheel with hand, make the screw mandrel band of rotation feed screw nut and the to-and-fro motion of flashboard along continuous straight runs, reach the keying purpose of gate.
The characteristics of above-mentioned spiral gate are: simple in structure, flexible operation, in light weight, no jam, cut off fast, the solid, the powder that are specially adapted to all kinds of no viscosity reach less than the granule of Φ 10mm, the conveying and the Flow-rate adjustment of crystal grain material, install and be not subjected to angle limits, easy to operate, can regulate aperture at any time.
But, in the prior art, when the material of spiral gate in control powder and undersized, because existing seal arrangement is simple and crude, very easily cause Lou material, and in actual use, pressure is bigger sometimes in its main frame, will cause the serious material that leaks, and production is caused great loss, because existing spiral gate is only finished sealing with two thin rubber plates, this when being sealed in actual use, often do not reach sealing effect, because two thin rubber plates are in use because the sealing dynamics is not enough, basically all can be caused this sealing as illusory by the distortion of the to-and-fro motion band of gate; Not easy to operate when changing rubber plate yet; Can not the blocked up rubber plate of used thickness, the blocked up to-and-fro motion that will influence the opening and closing of gate of thickness.
Summary of the invention
Problem to be solved by this invention provides a kind of spiral gate, its objective is the sealability that improves flashboard.
To achieve these goals, the technological scheme taked of the present invention is:
Spiral gate provided by the present invention, comprise the gate support body, flashboard, screw mandrel, screw rodb base, handwheel, the feed screw nut, described flashboard is horizontally disposed with, establish the sealing configuration of flashboard on the described gate support body, described sealing configuration is: the same position on the two sides of flashboard, respectively be provided with a stuffing box packing groove, described stuffing box packing groove is made of two baffle plates perpendicular to the strip of the moving direction of described flashboard, in described stuffing box packing groove, fill stuffing box packing, described stuffing box packing directly contacts with the surface of described flashboard, and described stuffing box packing is pressed on the surface of described flashboard by sealing clamp.
Establish sealed cover on the described gate support body, described sealed cover is fixedlyed connected with the gate support body, establishes a plurality of screws at described sealed cover, on the described screw housing screw is installed, and described housing screw is pressed on the described sealing clamp.
Establish a plurality of rollers on the described gate support body, described roller is distributed in the dual-side of the lower surface of described flashboard, the described flashboard of described roller wheel bearing, and the sense of rotation of described roller and the moving direction of described flashboard are tangent.
The present invention adopts technique scheme, and the dynamics that compresses of its Sealing can be regulated according to actual use condition, only need regulate Cock screw during adjusting and just can finish, and is easy to adjust simple, operation easily; The area of contact of Sealing and flashboard also increases greatly, and sealing effect is improved greatly, make spiral gate can be under the excessive situation of main frame pressure proper functioning still; In addition, the replacing after caulking gum uses wearing and tearing excessive also and simply only needs pressing plate is pulled down, and takes out original rubber plate, changes new rubber plate and gets final product.

Embodiment
Contrast accompanying drawing below, by description to embodiment, to effect and working principle, the manufacturing process of the mutual alignment between the shape of the specific embodiment of the present invention such as related each member, structure, the each several part and annexation, each several part and manipulate method etc., be described in further detail, inventive concept of the present invention, technological scheme had more complete, accurate and deep understanding to help those skilled in the art.
As Fig. 1, Fig. 2 and the expressed structure of the present invention of Fig. 3, be a kind of spiral gate, comprise gate support body 1, flashboard 4, screw mandrel 2, screw rodb base 3, handwheel 7, feed screw nut 5, described flashboard 4 is horizontally disposed with, and establishes the sealing configuration of flashboard 4 on the described gate support body 1.
Screw rodb base 3, roller 6 and flashboard 4 support bodys such as Fig. 1 to 3 assembling, and screw mandrel 2 one ends and handwheel 7 assemblings, the other end connects with nut 5, and nut 5 and the installation of 4 gates.
In order to solve the problem that exists at the described present known technology of this specification background technique part and to overcome its defective, realize improving the sealability of flashboard.Goal of the invention, the technological scheme that the present invention takes is:
As shown in Figure 1 to Figure 3, the sealing configuration of spiral gate provided by the present invention is: the same position on the two sides of flashboard 4, respectively be provided with a stuffing box packing groove, described stuffing box packing groove is made of two baffle plates perpendicular to the strip of the moving direction of described flashboard 4, in described stuffing box packing groove, fill stuffing box packing 9, described stuffing box packing 9 directly contacts with the surface of described flashboard 4, and described stuffing box packing 9 is pressed on the surface of described flashboard 4 by sealing clamp 10.
Defective at the prior art existence, the present invention improves the seal arrangement of spiral gate, seal arrangement after the improvement adopts Ge Jia about the original seal arrangement of the spiral gate position is welded a block plate, make it produce the space that to adorn rubber plate up and down, and this space is two up and down, and flashboard 4 passes from the centre of two passages, and the rubber plate in the passage is laterally placed, each seals with a dry plate more up and down
