The present application is described below with reference to specific embodiments in conjunction with the accompanying drawings:

as shown in fig. 1-4, this embodiment provides a wear-resistant grate screen, which includes a cast stone lining plate portion 2 and a grate portion 3, wherein the grate portion 3 is used for screening materials, the cast stone lining plate portion 2 is used for receiving the materials, that is, when the grate screen is used for screening materials, the poured materials firstly contact with the cast stone lining plate portion 2 and then fall onto the grate portion 3 for screening, and the cast stone lining plate portion 2 absorbs potential energy when the materials fall, so that the materials are prevented from directly contacting the grate portion 3 and damaging the grate portion 3.

The cast stone lining plate portion 2 comprises a plurality of lining plates 42, the plurality of lining plates 42 are all in a thin plate shape, the plurality of lining plates 42 are sequentially arranged so that the top surface of the cast stone lining plate portion 2 is in a plane to bear materials, in general, the top surfaces of the cast stone lining plate portion 2 and the grate portion 3 are obliquely arranged, and the cast stone lining plate portion 2 is positioned above the grate portion 3 in an inclined manner so that the materials fall under the action of gravity. The plurality of lining plates 42 are all vertically arranged, and it can be understood that the thin plate-shaped lining plates 42 are easy to fire, the cost is low, the intensity of the lining plates 42 in the vertical direction is high, the tops of the lining plates are used for bearing materials together, the single lining plates 42 are not easy to damage, operators can replace the single lining plates 42 after the single lining plates 42 are damaged, and the use cost is further reduced.

The grate section 3 is arranged at one discharging end of the cast stone lining plate section 2 to receive the material falling from the cast stone lining plate section 2, and the grate section 3 comprises a supporting piece 6 and a plurality of grate sections 5 arranged on the supporting piece 6 at intervals. The support piece 6 is arranged on the side plate 1 of the falling channel of the grate screen, the grate bars 5 are fixed on the grate screen, the length direction of the grate bars 5 is parallel to the moving direction of the materials on the grate bars 5, the number of the grate bars 5 is greatly reduced, and when the grate bars 5 are installed, the grate bars 5 are only required to be arranged according to the requirements in sequence, so that the time required for installing the grate bars 5 can be saved.

Referring to fig. 1, the cast stone lining plate part 2 includes a plurality of lining plate parts 4, the plurality of lining plate parts 4 are aligned such that the top surface of the cast stone lining plate part 2 is in a flat plate shape, the lining plate parts 4 include a frame 41, the top of the frame 41 is opened, a plurality of lining plates 42 are detachably provided in the frame 41, it is understood that the plurality of lining plates 42 in the same lining plate 42 part are sequentially aligned such that the top surface of a single lining plate part 4 is in a plane, and the inside of the frame 41 has a structure capable of fixing the lining plates 42, such as a chute, or the frame 41 is made to pinch the plurality of lining plates 42 integrally aligned. Most of the material falls in the middle of the cast stone lining plate part 2 in the falling process, the lining plates 42 in the middle are fast in loss speed and more serious in loss degree, a plurality of lining plates 42 are unitized through the lining plate parts 4, operators can conveniently and rapidly replace the lining plate parts 4 with serious loss in the middle of the cast stone lining plate part 2, and the lining plates 42 positioned at the edges of the cast stone lining plate part 2 are not seriously lost, so that the cast stone lining plate part can be temporarily replaced. Meanwhile, the loss degree of different lining plates 42 on the same lining plate piece 4 is also different, when the grate screen after the lining plate piece 4 is replaced carries out screening operation again, an operator can carry out recovery operation on the lining plate piece 4 after the replacement, the lining plates 42 with serious loss on the lining plate piece 4 are replaced, and the lining plate piece 4 after the replacement is stored for later use. The use cost is reduced, the shutdown time of the grate screen is shortened, and the screening efficiency of the grate screen is improved.

In order to ensure that the frame 41 of the liner member 4 can maintain a good form to be recovered, the height of the liner 42 is higher than the height of the frame 41 to reduce the probability of damage to the frame 41 by the material.

So as to reduce the gap between the lining plates 42, avoid material blockage, and improve the strength of the cast stone lining plate part 2. Referring to fig. 1 and 2, when a plurality of liner plates 4 are provided, a plurality of liner plates 42 within a single liner plate 4 are closely arranged.

The plane of the lining plates 42 is parallel to the direction of the grate 3. It will be appreciated that the gap at the top of adjacent liners 42 is oriented in the same direction as the grate bars 5, and in particular in the same direction as the material is moved over the grate screen, to reduce the likelihood of small particle size material being jammed between the liners 42 and thereby facilitate removal of the liners 42 from the frame 41 of the liner member 4.

Referring to fig. 3, the grate bars 5 include a base 51 and ceramic blocks 53, the base 51 is in a column shape, the base 51 of the grate bars 5 are parallel to each other, a limiting portion 52 is provided on the top surface of the base 51 along the length direction thereof, a recess portion matching with the limiting portion 52 is provided on the bottom surface of the ceramic block 53, the limiting portion 52 is engaged with the recess portion, and the base 51 and the ceramic block 53 are bonded by glue during the process of assembling the grate bars 5. The hardness of ceramic block 53 is high, receives the easy crackle of striking and even breaks, through setting up pedestal 51 in the below of ceramic block 53, in time ceramic block 53 breaks, and pedestal 51 also can support ceramic block 53 for ceramic block 53 still is located pedestal 51, avoids ceramic block 53 to break and leads to the grid section sieve to become invalid, and pedestal 51 adopts the metal to make, like steel or iron, and toughness is greater than ceramic block 53, difficult fracture.

The longer ceramic blocks 53 are also more difficult to fire, and the qualification rate of finished products is not high, so further, referring to fig. 3, a plurality of ceramic blocks 53 are arranged on the base body 51, the ceramic blocks 53 are sequentially arranged along the length direction of the grate bars 5, each ceramic block 53 is adhered to the base body 51, the manufacturing difficulty and cost of a single grate bar 5 are reduced by increasing the number of the ceramic blocks 53 on the same base body 51, and when the single ceramic blocks 53 are damaged, only the single ceramic block 53 can be replaced, so that the use cost of the grate bar screen is greatly reduced.

Further, referring to fig. 4, the two ends of the grate bar 5 are provided with a stopper 54, one end of the stopper 54 is fixedly connected with the end surface of the seat 51, and the other end of the stopper 54 abuts against the end surface of the ceramic block 53. The ceramic block 53 is limited by the stop block 54, and meanwhile, when the ceramic block 53 is mounted on the seat body 51, the stop block 54 also has a positioning function, so that the mounting efficiency of operators can be improved.

Referring to fig. 3, further, the ceramic block 53 has a trapezoid cross section, the width of the top surface of the ceramic block 53 is larger than that of the bottom surface of the ceramic block 53, and it can be understood that a channel reserved for the falling of materials is trapezoid between two adjacent grate bars 5, so that the channel is not easy to be blocked.
