Abstract
The invention relates to a grid plate which comprises a grid plate body. Mounting holes are formed in the two ends of the grid plate body, an oval groove is formed in the center of the grid plate body, a locating hole is formed in the oval groove, multiple grid holes are formed in the grid plate body, and the grid holes and the plane of the grid plate body are arranged obliquely. The grid plate is simple in structure, convenient to use, not prone to being blocked and large in capacity, and has good circulation, materials can pass through conveniently, a screening effect is good, production efficiency is improved, service life is prolonged, and production cost is lowered.
Description
Technical field
The present invention relates to a kind of grate plate.
Background technology
Grate plate is generally placed on groove top, ore deposit, mainly prevent because of freeze or rust joint become the bits shape of agglomerate or lump material to enter ore deposit groove after block ore deposit groove lower part outlet, due to the dither of grate plate, ore deposit groove is entered simultaneously preventing bulk materials, the normal material being less than sieve aperture can fall into rapidly ore deposit groove, and the caking large to some adhesion strengths can also play loose, the effect of fragment, be desirable groove top, ore deposit equipment, be widely used in the industries such as electric power, coal, mine, building materials, metallurgy, chemical industry.Grate plate is after material is broken, then carries out the key equipment that sieves, is applicable to the various ore of grinding and other material, is widely used in ore dressing, the industry such as building materials and chemical industry.The sieve aperture of conventional grate plate is generally perpendicular to plate body plane and arranges, and when inventory is large, easily blocks sieve aperture, affects production efficiency, can cause shutting down time serious.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in prior art, provides one to enhance productivity, not susceptible to plugging grate plate.
The technical solution adopted for the present invention to solve the technical problems is: a kind of grate plate, there is grate plate body, the two ends of described grate plate body are provided with installing hole, the center position of grate plate body is provided with oval-shaped groove, locating hole is provided with in oval-shaped groove, grate plate body is provided with some grate holes, and the planar tilt of grate hole and grate plate body is arranged.
Further, between described grate hole and grate plate body, inclination angle is 30-60 °.
Further, the shape of described grate plate body is fan-shaped.
Further, described grate plate body surface is through heat treatment process, and case hardness is HRC >=46 °.
The invention has the beneficial effects as follows: structure of the present invention is simple, easy to use, has good circulation, not easily blocks, content volume is larger, and be convenient to material and pass through, screening effect is good, enhances productivity, and increases the service life.Reduce production cost.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention;
Fig. 2 is the sectional view of B-B of the present invention.
1. grate plate bodies in figure, 2. installing hole, 3. oval-shaped groove, 4. locating hole, 5. grate hole.
Detailed description of the invention
The present invention is further illustrated with preferred embodiment by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
A kind of grate plate as shown in Figure 1, 2, there is grate plate body 1, the two ends of grate plate body 1 are provided with installing hole 2, the center position of grate plate body 1 is provided with oval-shaped groove 3, locating hole 4 is provided with in oval-shaped groove 3, grate plate body 1 is provided with some grate holes 5, grate hole 5 is arranged with the planar tilt of grate plate body 1, between grate hole 5 and grate plate body 1, inclination angle is 30-60 °, the shape of grate plate body 1 is fan-shaped, grate plate body 1 surface is through heat treatment process, and case hardness is HRC >=46 °, in 45 ° between sieve aperture 1 and plate body plane.Be the passage with grate plate body 1 plane orthogonal in the middle part of the grate hole 5 be obliquely installed, and there is the opening expanding and extend at the two ends of passage, make the content volume in grate hole 5 larger, being convenient to material passes through, and screening effect is good.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
