Description

Improved dosing device

technical field

The utility model relates to the field of iron and steel smelting, in particular to an improved material distribution device.

Background technique

Cold screening is one of the main processes and the last process in the production of sintering system in the iron and steel industry. In order to ensure the sustainability of production, two belt conveyor lines are usually established, one for backup and the other for use.

The utility model patent of Chinese Patent No. 201120496335.9 discloses a material distributor. When the material distributor is working, a push rod drives the material distribution plate to reciprocate on the upper part of the sieve plate, which can evenly distribute the materials on the sieve plate and realize switching The material distribution operation when feeding the belt. However, since the material of the distributor is usually block-shaped, it will collide with the pipe wall of the distributor when feeding, resulting in serious wear of the pipe wall of the distributor and shortening the service life of the distributor.

SUMMARY OF THE INVENTION

The purpose of this utility model is to provide an improved material distribution device.

The technical scheme for realizing the purpose of the present utility model is: an improved material distribution device, which comprises a material distributor body, and the material distributor body has a material inlet and two bifurcated material distribution pipes which are communicated with the material inlet. , a material distribution plate for blocking the material distribution pipe is installed inside the material distributor body, and a material accumulation plate inclined upward relative to the horizontal plane is arranged on the inner pipe wall of each of the material distribution pipes, which is susceptible to impact. The length of the accumulation plate is based on the fact that the broken materials can be accumulated on the accumulation plate to form a protective layer on the pipe wall.

Further, a dividing plate that can be turned over to the nozzles of the two feeding tubes is installed at the boundary between the feeding port and the feeding tube, and the feeding plate is fixedly installed on a turning mechanism and penetrates into the body of the feeding device. on the rotating shaft inside and rotates with the rotating shaft of the turning mechanism.

In the utility model, a material accumulation plate is arranged on the inner pipe wall of the material distribution pipe, and the crushed materials are hung on the material accumulation plate during feeding to form a pipe wall protection layer, thereby effectively protecting the inner wall of the material distribution pipe and prolonging the use of the material distribution device. life.

Fig. 1 is the internal structure schematic diagram of the improved material distribution device described in the embodiment of the present utility model;

FIG. 2 is a schematic diagram of the installation structure of the turning mechanism and the distribution plate according to the present invention.

Detailed ways

The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

As shown in FIG. 1 and FIG. 2 , an improved material distribution device includes a material distributor body 1 , and the material distributor body 1 has a material inlet 11 and two bifurcated branches communicating with the material inlet 11 . The material distribution pipe 12, a material distribution plate 2 that can be turned over to the nozzles of the two material distribution pipes 12 is installed at the boundary between the material inlet 11 and the material distribution pipe 12, and the material distribution plate 2 is fixedly installed on a flip The mechanism 3 penetrates into the rotating shaft 31 in the body of the dispenser and rotates with the rotating shaft 31 of the overturning mechanism; the inner pipe wall 121 of each of the dispensing pipes 12 susceptible to impact is provided with a material accumulation plate inclined upward relative to the horizontal plane 4. The length of the accumulating plate 4 is 80-100 mm, and the broken materials during operation are accumulated on the accumulating plate 4 to form a protective layer of the pipe wall.

The structure of the turning mechanism of the present invention belongs to the prior art and will not be repeated here.

When the finished ore needs to fall from the left distribution pipe, the turning mechanism drives the distribution plate to turn over to the right distribution pipe to close the nozzle of the right distribution pipe, and then the finished ore passes through the left distribution pipe from the feeding port. The nozzle falls down, and part of the broken material hangs on the accumulation plate to form a protective layer of the pipe wall, and then the material hits the protective layer of the pipe wall during the blanking process and will not rub against the pipe wall, thus prolonging the life of the distributor. .

The material distribution plate installation structure of the present invention is not limited to those shown in the embodiments, and a retractable material distribution plate controlled by a cylinder can also be installed at the nozzle of each material distribution pipe, and the cylinder at the corresponding material distribution pipe extends out. When the corresponding material distribution plate blocks the material distribution pipe, the structure of the reversible material distribution plate arranged at the boundary between the feeding port and the material distribution pipe in the present invention is more compact; the material accumulation plate is inclined The angle and length are usually 80-100mm, but they can be set according to the particle size and quality of the material in the actual production process, as long as the broken material can be accumulated on the accumulation plate to form a protective layer on the pipe wall.

The above are only the embodiments of the present invention, and are not intended to limit the scope of the patent of the present invention. Any equivalent process transformation made by using the contents of the description of the present invention, or directly or indirectly used in other related technical fields, are the same as The principles are included in the scope of patent protection of the present invention.
