Description

Refractory brick raw material vibrating screen

technical field

The utility model belongs to the technical field of refractory material production, in particular to a vibrating screen for refractory brick raw materials.

Background technique

At present, the raw materials of refractory bricks need to be screened after crushing. Many manufacturers still use manual screening, which is labor-intensive and low in production efficiency. Some also use mechanical screening equipment. They are collected separately according to particle size, and the screening effect is not good, and there are many impurities mixed in, such as iron filings, which affects the production quality of refractory bricks.

Utility model content

In order to solve the deficiencies in the prior art, the utility model provides a refractory brick raw material vibrating screen with low labor intensity, high work efficiency and good screening effect.

In order to solve the above-mentioned technical problems, the utility model adopts the following technical scheme: the raw material vibrating screen for refractory bricks, including the frame and the vibrating box. There are upper screen, middle screen and lower screen from top to bottom inside. The screen hole of the upper screen is larger than the screen hole of the middle screen, and the screen hole of the middle screen is larger than the screen hole of the bottom screen. Vibration The top of the box is provided with a feed inlet at the higher end of the upper screen, and the vibrating box is provided with a recycling port at the lower end of the upper screen, and the lower end of the middle screen is connected with a coarse material discharge pipe. The lower end of the net is connected with the medium material discharge pipe, the lower end of the bottom of the vibrating box is connected with the fine material discharge pipe, and the upper end of the coarse material discharge pipe, the upper end of the medium material discharge pipe and the fine material are connected on the inner wall of the vibration box. A high-strength magnet is respectively arranged at the upper end of the feeding pipe.

With the above technical scheme, the pulverized raw materials are conveyed into the vibrating box by the bucket elevator through the feeding port, the vibrating motor is turned on, and the whole vibrating box starts to vibrate, and the raw material particles are separated from large to small in order, and the raw materials that cannot pass through the upper screen The raw materials that pass through the upper screen and cannot pass through the middle screen fall into a hopper of the storage bin through the coarse material discharge pipe, and the materials that pass through the middle screen but cannot pass through the lower screen pass through the middle screen. The material feeding pipe falls into the second hopper of the storage bin, and the raw material passing through the lower screen falls into the third hopper of the storage bin through the fine material feeding pipe. When raw materials of different sizes fall into the hopper, the high-strength magnets will absorb the iron filings in the raw materials, thereby reducing the iron filings in the raw materials, and cleaning the iron filings on the magnets at intervals.

The utility model is simple in structure and reasonable in design, so that the raw materials of refractory bricks can be well screened, screened more cleanly, and classified and collected according to different sizes, with high degree of automation, greatly improved production efficiency, low labor intensity, strong practicability, and easy popularization and application. .

Detailed ways

As shown in Figure 1, the refractory brick raw material vibrating screen of the present utility model comprises a frame 1 and a vibrating box 2, the bottom of the vibrating box 2 is arranged on the frame 1 by a compression spring 3, and the bottom of the vibrating box 2 is connected with a vibrating motor 4, The vibrating box 2 is inclined from top to bottom with an upper screen 5, a middle screen 6 and a lower screen 7. The screen hole of the upper screen 5 is larger than the size of the middle screen 6, and the screen hole of the middle screen 6 Larger than the mesh size of the lower screen 7, the top of the vibrating box 2 is provided with a feeding port 8 at the higher end of the upper screen 5, and the vibrating box 2 is provided with a recycling port 9 at the lower end of the upper screen 5. The lower end of the screen cloth 6 is connected with a coarse material feeding pipe 10, the lower end of the lower screen cloth 7 is connected with a middle material feeding pipe 11, and the lower end of the vibration box 2 bottom is connected with a fine material feeding pipe 12, A high-strength magnet 13 is respectively provided with the upper end of the coarse material blanking tube 10, the middle material blanking tube 11 upper end and the fine material blanking tube 12 upper end on the vibrating box 2 inner side walls.

When the utility model is working, the pulverized raw materials are transported into the vibrating box 2 by the bucket elevator through the feeding port, the vibrating motor 4 is turned on, and the whole vibrating box 2 starts to vibrate, and the raw material particles are separated from large to small in order, and cannot pass through The raw materials of the upper screen 5 are discharged through the recovery port and then crushed. The raw materials that pass the upper screen 5 but cannot pass through the middle screen 6 fall into a hopper of the storage bin through the coarse material discharge pipe 10, and pass through the middle screen. 6 Raw materials that cannot pass through the lower screen 7 fall into the second hopper of the storage bin through the middle material feeding pipe 11, and the raw materials that pass through the lower screen 7 fall into the second hopper of the storage bin through the fine material feeding pipe 12. Inside the third hopper. When raw materials of different sizes fall into corresponding hoppers, the high-strength magnet 13 absorbs the iron filings in the raw materials, thereby reducing the iron filings in the raw materials, and cleaning the iron filings on the high-strength magnet 13 after a period of time.
