Abstract
Disclosed is a constant square hole flat plate type gate. The constant square hole flat plate type gate comprises a rectangular gate frame (1) used as a gate framework, a feed port (2) arranged on the gate frame (1), and a gate plate (3) which is installed in the gate frame, driven by a transmission device (5) and supported by supporting wheels (4). The constant square hole flat plate type gate is characterized in that the feed port (2) is in a square structure installed obliquely in 45 degrees; a starting and stopping end of the gate plate (3), matched with the feed port, is in a 90-degree fork-type structure; and the feed port and the gate plate form a constant square hole material through hole in the process of starting.
Description
Technical field
The present invention relates to be applicable to the flat gate of constant square hole of keying and the flow control of various bulk material storage warehouse discharging openings, belong to bulk material processing and storing technology field.
Background technology
Gate be the processing of various bulk materials with storage process in requisite equipment, nearly all storage warehouse or the discharging opening of storage bin(hopper) all will be installed gate, are used for realizing the open and close of discharging opening and control the flow of material.
Flat gate in the past is divided into two kinds, square gate and circular gate according to the shape of its latus rectum.The gate of which kind of shape no matter, their opening ways is all the same: when flashboard pulls out, first open a slit in latus rectum, afterwards along with flashboard continue pull out, slit broadens gradually, until gate is thoroughly opened square or circular material hole of rear formation.But change the aperture of the distance control door that flashboard pulls out, can reach and control the deliver from godown purpose of flow of material.Yet when the flow of the material that delivers from godown was very little, the aperture of gate was also very little, and the material hole of opening in latus rectum is one " slit " (seeing shown in Fig. 1,2).Because this material hole is very narrow, material is easy to form obstruction because of the existence of various impurity when flowing through this hole.
The gate of a kind of " aperture-type " in addition, this gate is similar to the aperture of photographic camera, be arc flower sheet by multi-disc along circumference and overlapped, form one and be similar to round material hole.The characteristics of this " being similar to " circular hole are exactly " slit " that is different from bulkhgead gate, and it is conducive to the stationary flow of material, is not prone to latch up phenomenon.But this gate structure is more complicated, and the colored sheet of aperture is thinner, and aperture is difficult for opening or occurs distortion when its top material pressure is excessive, therefore is not suitable for making the gate of large specification
Summary of the invention
The flat gate of a kind of constant square hole that purpose of the present invention provides for existing weak point in above-mentioned prior art just.Gate of the present invention makes gate remain a constant square material hole when opening by the structure that changes existing flat gate and the flashboard that adopts special shape, rather than narrow " gap ".The characteristics that gate existing structure of the present invention is simple, intensity is high, pressure resistance is large have again constant square material hole simultaneously, guarantee that Flow of Goods and Materials is smooth and easy, reach the purpose of stablizing mass flow.
Purpose of the present invention can realize by following technique measures:
The flat gate of constant square hole of the present invention comprises rectangle lock frame as the gate skeleton, be arranged on the inlet point on the lock frame and be arranged in the lock frame by actuator drives and by the flashboard of support roller support, wherein said inlet point is the square structure of 45 ° of installations of deflection; The keying end that described flashboard matches with inlet point is the forked type structure of 90 °; The constant square hole material hole of the common formation of inlet point and flashboard in opening process.
More specifically: the lock frame is the skeleton of gate, and other member all is fixed on the lock frame.Foursquare inlet point is positioned at the upper plane of lock frame, with 45 ° of installations of its deflection, makes the line of centers of its diagonal line and lock frame overlapping.The keying end that described flashboard matches with inlet point is the forked type structure of 90 °, is embedded in the lock frame, is close to " blocking " material below inlet point, and inlet point can vertically move along the lock frame on support roller, thereby changes the aperture of gate.The movement of flashboard is controlled by driving device (manual, electronic or pneumatic).
When unlatching or closed shutter (change aperture), open and close end and be the flashboard of 90 ° of forked type structures and 90 ° of material holes that the angles formation is square of inlet point.Flashboard is pulled out more backward, and the bore of square material hole is larger, until reach the required size of inlet point.
Beneficial effect of the present invention is as follows:
The present invention efficiently solves ordinary flat formula gate " slit " problem when little aperture, makes gate under any aperture, and the material hole of opening is square.Foursquare material hole be difficult for to stop up, mass flow is stable, and the flow control of the material that is very beneficial for delivering from godown can replace some to quantify bin device to a certain extent.

The specific embodiment
The present invention is further described below with reference to embodiment (accompanying drawing):
As shown in Fig. 3,4, the flat gate of constant square hole of the present invention comprises rectangle lock frame 1 as the flashboard skeleton, be arranged on the inlet point 2 on lock frame 1 and be arranged on being driven and by the flashboard 3 of support roller 4 supports, wherein said inlet point 2 is the square structure of 45 ° of installations of deflection by driving device 5 in the lock frame; The keying end that described flashboard 3 matches with inlet point is the forked type structure of 90 °.
More specifically: the lock frame is the skeleton of gate, and other member all is fixed on the lock frame; Foursquare inlet point is positioned at the upper plane of lock frame, with 45 ° of installations of its deflection, makes diagonal line and the flashboard longitudinal center line overlap of square inlet point.The keying end that described flashboard matches with inlet point is the forked type structure of 90 °, is embedded in the lock frame, is close to " blocking " material below inlet point, and inlet point can vertically move along the lock frame on support roller, thereby changes the aperture of gate.The movement of flashboard is controlled by driving device (manual, electronic or pneumatic).
When unlatching or closed shutter, open and close end and be the flashboard of 90 ° of forked type structures and 90 ° of material holes that the angles formation is square of inlet point, flashboard is pulled out more backward, and the bore of square material hole is larger, until reach the required size of inlet point.
