Abstract
The invention discloses a checking screen which comprises a screen frame and a screen net arranged in the screen frame. The screen net is detachably connected with the screen frame. A supporting net is arranged at the bottom of the screen net, and a plurality of steel balls are arranged between the supporting net and the screen net. The supporting net is a steel wire net with the grid diameter smaller than the diameter of each steel ball by 2-5 mm. An opening is formed in one side of the screen frame. By means of the structure, the steel balls can freely jump between the screen net and the supporting net and impact the bottom of the screen net continuously, and therefore the screen net is automatically cleaned and blocking of meshes of the screen net is prevented. Meanwhile, the steel balls are resistant to abrasion and low in noise and have no harm to the human body. In addition, the supporting net can bear the weight of powder on part of the screen net, and therefore deformation of the screen net is prevented.
Description
Technical field
The present invention relates to a kind of particle powder verifying attachment, particularly a kind of test sieve.
Background technology
In particle powder, as feed, magnetic, zirconia powder etc., there is an important Index for examination, be that the grain diameter of powder is sieved, the production line that partial automation degree is high, is directly connected on finished product discharging opening by test sieve, after screening, then carry out package handling.Yet, existing test sieve, automatic cleaning net scarce capacity, was used after a period of time, and because of reasons such as powder self water content are large or fine powder is many, the screen cloth of test sieve will be crammed, and screening efficiency is declined, and screening precision is not high,
The day for announcing is on May 6th, 2009, name is called No. 200820148448.8 Chinese utility model patent of " ultrasonic standard inspection sieve ", it is to be provided with supersonic generator near on the screen frame of screen cloth, and connect the ultrasonic wave controller outside sieve nest by wire, by ultrasonic wave controller, control the dither of supersonic generator, peel off the absorption affinity between material particulate, and increase the vibration force of material on screen cloth.This test sieve can improve screening efficiency to a certain extent, but also brings new problem, because of the high frequency fast vibration of material, to the part particle of particle powder be destroyed, fine powder increases, and defective work increases, meanwhile, ultrasonic wave noise is large, large to operating personnel's actual bodily harm.
Summary of the invention
The technical problem to be solved in the present invention is for above-mentioned the deficiencies in the prior art, and provide a kind of can Automatic clearance screen cloth, prevent that screen cloth mesh from stopping up, screening efficiency high and to human body the test sieve without injury.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of test sieve, comprise screen frame and be placed in the screen cloth in screen frame, described screen cloth and screen frame are for removably connecting, described screen bottom is also provided with supporting network, between this supporting network and screen cloth, be provided with several steel balls, described supporting network be its grid diameter than the steel wire of the little 2-5mm of each steel ball size, described screen frame one side is provided with outlet.
Described steel ball is the chromium steel ball that hardness is greater than 55 degree.
Described screen frame comprises upper ledge and the lower frame of mutual clamping, and described screen cloth is fastened between upper ledge and lower frame, and stretches out from access section, and described supporting network is welded on lower frame bottom.
The present invention adopts after said structure, and above-mentioned steel ball can freely be beated between screen cloth and supporting network, does not stop impact screen bottom, thereby reaches Automatic clearance screen cloth, prevents the obstruction of screen cloth mesh, and steel ball is wear-resistant simultaneously, and noise is little, to human body without injury.In addition, supporting network also can be born the weight of powder on part screen cloth, prevents the distortion of screen cloth.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of test sieve of the present invention.
Wherein have: 1. screen frame; 2. screen cloth; 3. supporting network; 4. steel ball; 5. outlet; 6. grid.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further detailed explanation with concrete better embodiment.
As shown in Figure 1, a kind of test sieve, comprises screen frame 1 and is placed in the screen cloth 2 in screen frame 1, screen frame 1 comprises upper ledge and the lower frame of mutual clamping, and described screen cloth 2 is fastened between upper ledge and lower frame, and stretches out from access section.Described screen cloth 2 bottoms are also provided with supporting network 3, and preferably supporting network 3 is welded on lower frame bottom; Between supporting network 3 and screen cloth 2, be provided with several steel balls 4, supporting network 3 be its grid 6 diameters than the steel wire of the little 2-5mm of each steel ball 4 diameter, supporting network 3 can be born the weight of powder on part screen cloth 2, prevent the distortion of screen cloth 2, in addition, steel wire itself is not yielding, does not need frequent replacing.Further, grid 6 diameters, than the little 2-5mm of each steel ball 4 diameter, can prevent from passing through grid 6 after steel ball 4 wearing and tearing on the one hand, on the other hand, do not affect flowing freely of particle powder.
Above-mentioned screen frame 1 one sides are provided with outlet 5, and this outlet 5 is preferably arranged on the screen frame 1 slightly biased upper/lower positions in middle part, when not affecting normal screening effect, can make to sieve the powder of rear acceptance or rejection, from then on export in 5 and flow out, thereby do not need sieve nest.
Described steel ball 4 is greater than the chromium steel ball of 55 degree for hardness, wear-resistant, does not need often to change steel ball.
Described screen cloth 2 also can prevent between the upper ledge and lower frame of screen frame 1, and upper ledge and lower frame are fixed by check bolt or other the mode that removably connects, thereby facilitates replacing and the cleaning of screen cloth 2.
During use, steel ball 4 can freely be beated between screen cloth 2 and supporting network 3, does not stop impact screen 2 bottoms, thereby reaches Automatic clearance screen cloth 2, prevents the obstruction of screen cloth 2 mesh, and simultaneously steel ball 4 is wear-resistant, and noise is little, to human body without injury.
