Detailed implementation manners

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-4 , the present invention provides a technical solution: a vibrating screening device for refractory materials, including a frame 1; a vibrating screen box 2 is arranged on the frame 1; a feed hopper 3 is arranged on one side of the top of the vibrating screen box 2 for adding refractory materials; a crushing assembly 4 is arranged in the feed hopper 3 for crushing the agglomerated refractory materials. During use, the refractory materials placed in the feed hopper 3 are crushed by the crushing assembly 4, effectively preventing the agglomerated refractory materials from directly falling onto the filter screen assembly 6, ensuring the screening effect and avoiding material waste; a number of material distribution plates 5 are arranged, distributed in the vibrating screen box 2 and below the feed hopper 3, and a number of material distribution channels are formed between the material distribution plates 5 and the inner wall of the vibrating screen box 2; a number of vibrating screen assemblies 6 are arranged, inclined in the vibrating screen box 2, and the feed end of the vibrating screen assembly 6 is arranged corresponding to the lower part of each material distribution channel; a number of discharge assemblies 7 are arranged on the vibrating screen box 2 for conveying the refractory materials screened by the vibrating screen assembly 6. When the screening equipment removes impurities, the refractory materials falling from the feed hopper 3 are distributed by a number of material distribution plates 5 and enter different vibrating screen assemblies 5 for screening, so that a large amount of refractory material raw materials are spread out by a number of vibrating screen assemblies 5, enabling the materials to be thoroughly screened, avoiding the problem that some refractory materials do not fall below the sieve plate but instead enter the impurities, and effectively reducing the problem of material waste.

[0026] Specifically, the vibrating screen assembly 6 includes a vibrating trough body 6-1 disposed inside the vibrating screen box 2. A vibrating screen 6-2 is provided at the upper end of the vibrating trough body 6-1, and a discharge hopper 6-3 is provided at the lowest end of the vibrating trough body 6-1. During use, when the vibrating screen box 2 drives the vibrating screen 6-2 to vibrate, the screened refractory materials fall into the inner side of the vibrating trough body 6-1. Along with the vibration of the vibrating screen box 2, the screened refractory materials move downward along the inclined vibrating trough body 6-1 and are discharged from the discharge hopper 6-3, realizing the screening operation of the refractory materials.

[0027] Specifically, the discharge assembly 7 includes a cylinder body 7-1 disposed on the vibrating screen box 2. A collecting hopper 7-2 is provided at the top of the cylinder body 7-1 corresponding to the discharge end of the vibrating screen assembly 6. A first driving motor 7-3 is provided at one end of the cylinder body 7-1. The driving end of the first driving motor 7-3 extends into the cylinder body 7-1 and is provided with a spiral conveyor auger 7-4. The other end of the cylinder body 7-1 extends out of the vibrating screen box 2 and is provided with a discharge channel 7-5. During use, the refractory materials screened by the vibrating screen assembly 6 enter the inner side of the cylinder body 7-1 through the collecting hopper 7-2. By starting the first driving motor 7-3 to drive the spiral conveyor auger 7-4 to rotate, the screened refractory materials are conveyed and discharged from the discharge channel 7-5, realizing the collection and conveyance of the refractory materials screened by the vibrating screen assembly 6.

[0028] Specifically, the crushing assembly 4 includes two crushing rolls 4-1 rotatably installed opposite to each other in the feed hopper 3. Gear wheels 4-2 meshing with each other are provided at the shaft ends of the two crushing rolls 4-1. A second driving motor 4-3 for driving one of the gear wheels 4-2 to rotate is provided on the vibrating screen box 2. During use, by driving the second driving motor 4-3 to drive one of the gear wheels 4-2 to rotate, one of the gear wheels 4-2 drives the other gear wheel 4-2 to rotate, realizing that the second driving motor 4-3 drives the two crushing rolls 4-1 to rotate relative to each other at the same time. When the agglomerated refractory materials fall, the agglomerated refractory materials are crushed by the relative rotation of the two crushing rolls 4-1, preventing the agglomerated refractory materials from falling onto the vibrating screen assembly and not falling below the sieve plate, but instead entering the impurities, effectively preventing the agglomerated refractory materials from directly falling onto the filtering screen assembly, ensuring the screening effect and avoiding material waste.

[0029] Specifically, a collecting box 8 is provided at the bottom of the vibrating screen box 2. By providing the collecting box 8, the impurities screened out by a plurality of vibrating screen assemblies 6 are collected.

[0030] Working principle: When the utility model is in use, first start the vibrating screen box 2 and the crushing component 4. After the refractory material enters from the feed hopper 3, it is first crushed by the crushing component 4. The crushed refractory material is divided by the material distribution plate 5, so that the refractory material enters different vibrating screen components 6 for screening respectively. The screened refractory material enters the discharging component 7 for conveying, ensuring the screening effect of the refractory material.
