Description

Sieve plate

Technical Field

The utility model relates to a screening plant field of mining equipment, concretely relates to sieve.

Background

In various crushing and grinding process flows of a dressing plant, ores need to be pre-screened or inspected and screened, so that products reaching qualified particle sizes in the ores are separated as early as possible through screening, and the processing capacity of the whole crushing and grinding process flow is improved.

The prior art has the following defects: the existing sieve plates used in equipment are mostly of simple punching structures, so that the problems of sieve pore blockage, low sieving efficiency and the like of the sieve plates often occur, on one hand, the productivity of a concentrating mill is difficult to improve, and on the other hand, the service load of other equipment is increased, so that the production cost is increased.

Therefore, the novel sieve plate is necessary to be invented.

SUMMERY OF THE UTILITY MODEL

For this reason, the utility model provides a sieve sets up the cross-section that toper, water conservancy diversion piece through the sieve mesh cross-section and sets up to the toper, carries out the water conservancy diversion to the material to solve current sieve and often can appear the sieve mesh jam, the screening inefficiency of sieve, the productivity that leads to the concentrating mill on the one hand is difficult to improve, and on the other hand can increase the service load of other equipment and lead to the problem that manufacturing cost increases.

In order to achieve the above object, the present invention provides the following technical solutions: the sieve plate comprises a sieve body and a flow guide block, sieve holes are uniformly formed in the inner wall of the sieve body, the sieve holes are square, the cross sections of the sieve holes are tapered, and the flow guide block is uniformly arranged on the upper surface of the sieve body.

Preferably, the upper surface and the lower surface of the screen body are rectangular, and the cross section of the screen body is rectangular.

Preferably, the blanking direction of the sieve holes is perpendicular to the lower surface of the sieve body.

Preferably, the upper surface of the sieve mesh is smaller than the lower surface of the sieve mesh.

Preferably, the cross section of the diversion block is conical and is distributed among the sieve holes along the material flowing direction.

Preferably, the screen body is made of rubber.

The utility model has the advantages that: the cross-section of sieve mesh sets up to the toper, makes things convenient for the material to pass through the sieve mesh smoothly, and the cross-section of water conservancy diversion piece sets up to the toper, carries out the water conservancy diversion with the material to the sieve mesh to improve material and sieve mesh fully contact, thereby guarantee the screening efficiency of material.

In the figure: screen frame 1, water conservancy diversion piece 2, sieve mesh 3.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

Referring to the attached drawings 1-2, the utility model provides a sieve plate, including screen frame 1 and water conservancy diversion piece 2, screen mesh 3 is evenly seted up to screen frame 1 inner wall, screen mesh 3 sets up to square, the cross-section of screen mesh 3 sets up to the toper, water conservancy diversion piece 2 evenly sets up at the upper surface of screen frame 1, and screen frame 1 has the screening effect to mineral (not reference numeral in the figure), has the effect of connection fixed to water conservancy diversion piece 2, and water conservancy diversion piece 2 has the guide effect to mineral, and screen mesh 3 has the circulation effect to mineral, and screen mesh 3 sets up to square, is favorable to improving mineral screening effect;

furthermore, the upper surface and the lower surface of the screen body 1 are rectangular, and the section of the screen body 1 is rectangular, so that the modular installation of the screen plate is facilitated;

furthermore, the blanking direction of the sieve holes 3 is vertical to the lower surface of the sieve body 1, so that the minerals above the sieve body 1 can be conveniently screened, and the problem of blockage of the sieve holes 3 is avoided;

furthermore, the size of the upper surface of the sieve pore 3 is smaller than that of the lower surface of the sieve pore 3, so that the sieve pore 3 is favorable for screening minerals, the sieve pore 3 is favorable for grading the granularity of the minerals, and the capacity of a concentrating mill is improved;

furthermore, the section of the flow guide block 2 is conical, and is distributed among the sieve pores 3 along the material flowing direction, and the section of the flow guide block 2 is conical, so that the mineral guiding effect is good, the sieve pores 3 are favorable for grading the mineral granularity, and the production capacity of a concentrating mill is improved;

further, screen frame 1 sets up to the rubber material, is favorable to protecting screen frame 1.

The utility model discloses a use as follows: when the utility model is used, a person skilled in the art pours materials into the upper surface of the screen body 1, the flow guide block 2 of the screen body 1 is along the material flow direction, and when the screen body 1 is used for material screening, the materials can smoothly pass through the screen holes 3 because the cross sections of the screen holes 3 are set to be conical; the upper surface through screen frame 1 has water conservancy diversion piece 2, with material granule to 3 water conservancy diversion of sieve mesh for the material screening is more abundant, has improved the operation ability of screening equipment, has reduced the service load of other equipment, has improved the productivity of ore dressing plant greatly.

The above description is only a preferred embodiment of the present invention, and any person skilled in the art may modify the present invention or modify it into an equivalent technical solution by using the technical solutions described above. Therefore, any simple modifications or equivalent replacements made according to the technical solution of the present invention belong to the scope of the claimed invention as far as possible.
