Abstract
The invention discloses an anti-blockage device of a partition bin grid plate. The anti-blockage device comprises a base plate, and is characterized in that the base plate is provided with a front-and-back through feeding channel for materials to pass through; a screen consistent with the feeding channel in section shape is arranged on the feeding channel of the base plate; the area of the screen is larger than or equal to the area of the feeding channel; a plurality of screen positioning holes are formed in the base plate around the feeding channel by one circle; and the screen is provided with a plurality of feeding holes for crushed materials to pass through. When hardened cement or crushed steel balls arrive at the corresponding feeding holes, due to conical hole structures of the feeding holes, the steel balls or the hardened cement impact each other in the feeding holes along with the screening rhythm of the device during working, consequently, reverse acting force is obtained after parts of the hardened materials or the steel balls enter the feeding holes, and accordingly the passing rate through the device is greatly increased. Compared with a traditional screen structure, the passing rate through the device reaches about 20%.
Description
Technical field
The present invention relates to a kind of compartment grate plate preventing clogging up device, particularly relate to a kind of compact conformation, compartment grate plate preventing clogging up device that percent of pass is high.
Background technology
In cement material whipping process, because of the moisture doped with 1% ~ 2% in stone flour, thus harden, and once harden, traditional filter screen device is because its sieve aperture is that cylindrical hole adds circular cone structure, and traditional sieve aperture uses cylindrical hole that sectional area is less more near charging side, the feed blocking sieve aperture after will hardening to a certain extent must be caused, in addition in whipping process because using steel ball, once steel ball fragmentation will be easy to be stuck in the cylindrical hole of sieve aperture, thus aggravate blocking further.On screen cloth traditional in addition, the distribution of sieve aperture mostly is several strip groove, adopts this structure, after wherein a part blocks, can progressively affect place rectangular slot until block rectangular slot completely.The percent of pass of structure traditional is at present about 8%, thus causes the working (machining) efficiency of cement flour to decline.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of compartment grate plate preventing clogging up device, has compact conformation, feature that percent of pass is high.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of compartment grate plate preventing clogging up device, comprise substrate, its innovative point is: the feeding-passage passed through for material through before and after described substrate is provided with, described substrate upper feeding channel position place is provided with the screen cloth consistent with the cross sectional shape of described feeding-passage, the thickness of described screen cloth is less than or equal to 6mm, the area of described screen cloth is greater than or equal to the area of described feeding-passage, described in described substrate pressed on ring, feeding-passage is provided with several screen cloth locating hole for one week, described screen cloth has several charging hole passed through for comminuting matter, the inwall of this charging hole is bellmouth, and the charging side of this charging hole is large end, the length dimension of the large end of this charging aperture is less than or equal to 30mm, the width dimensions of the large end of this charging aperture is less than or equal to 5mm.
Preferably, the inwall of described feeding-passage upper feeding passage is inclined-plane, and the gradient on described inclined-plane is 1:3 ~ 1:5.
Preferably, the gradient on described inclined-plane is 1:4.
Preferably, described screen cloth locating hole is shoulder hole.
Preferably, the cross section of described charging hole is kidney-shaped.
Preferably, the tapering of described charging aperture is 1:1.5.
Preferably, described screen cloth is abrasion-proof stainless steel material.
The invention has the advantages that: by arranging the feeding-passage that inwall is inclined-plane, and screen cloth is set on feeding-passage, screen cloth arranges the charging hole of several bellmouth form, and the large end of charging hole is near charging side, thus when having the cement after hardening or the steel ball after fragmentation arrives corresponding charging hole, because of the bellmouth structure of charging hole, steel ball or the cement after hardening will companion devices work time sieve rhythm, clash in charging hole after causing the material after hardening or steel ball part to enter charging hole and obtain an opposition, thus substantially increase the percent of pass of device, compared to traditional mesh structure, the percent of pass of device of the present invention reaches about 20%.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation;
Fig. 1 is the structural representation of a kind of compartment grate plate of the present invention preventing clogging up device;
Fig. 2 is the A-A sectional view of Fig. 1;
In figure: 1-substrate, 2-feeding-passage, 3-screen cloth, 4-screen cloth locating hole, 5-charging hole.
Detailed description of the invention
Compartment grate plate preventing clogging up device of the present invention, comprise substrate 1, the feeding-passage 2 passed through for material through before and after substrate 1 is provided with, substrate 1 upper feeding passage 2 position is provided with the screen cloth 3 consistent with the cross sectional shape of feeding-passage 2, the thickness of screen cloth is less than or equal to 6mm, the area of screen cloth 3 is greater than or equal to the area of feeding-passage 2, substrate 1 pressed on ring feeding-passage is provided with several screen cloth locating hole 4 for 2 one weeks, screen cloth 3 has several charging hole 5 passed through for comminuting matter, the inwall of this charging hole 5 is bellmouth, the cross section of charging hole 5 is kidney-shaped and the charging side of this charging hole 5 is large end, the length dimension of the large end of this charging aperture is less than or equal to 30mm, the width dimensions of the large end of this charging aperture is less than or equal to 5mm.
The inwall of above-mentioned feeding-passage 2 upper feeding passage 2 is inclined-plane, and the gradient on this inclined-plane is 1:3 ~ 1:5, and theoretical effect shows, the best results when gradient on inclined-plane is 1:4.
For the ease of better location, screen cloth locating hole 4 is shoulder hole.In order to better prevent feed blocking charging hole 5, the tapering of charging aperture is 1:1.5.In order to improve the abrasion resistance properties of device, screen cloth 3 is abrasion-proof stainless steel material.
Concrete, by arranging the feeding-passage 2 that inwall is inclined-plane, and screen cloth 3 is set on feeding-passage 2, screen cloth 3 arranges the charging hole 5 of several bellmouth form, and charging hole 5 is the close charging side of end greatly, thus when having the cement after hardening or the steel ball after fragmentation arrives corresponding charging hole 5, because of the bellmouth structure of charging hole 5, steel ball or the cement after hardening will companion devices work time sieve rhythm, clash in charging hole 5 after causing the material after hardening or steel ball part to enter charging hole 5 and obtain an opposition, thus blocking is less likely to occur.
Finally it should be noted that, above embodiment is only in order to illustrate technical scheme of the present invention and non-limiting technical scheme, those of ordinary skill in the art is to be understood that, those are modified to technical scheme of the present invention or equivalent replacement, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of right of the present invention.
