Weighing device for refractory brick raw materials

Abstract

The invention relates to a weighing device used in the preparation process of refractory bricks in the iron and steel industry, and specifically relates to a weighing device for refractory brick raw materials. The weighing device comprises a frame which is sequentially equipped with a storage hopper, a first weighing hopper, a second weighing hopper and a receiving box from top to bottom. The feed inlet of the first weighing hopper is disposed right below the discharge outlet of the storage hopper, the feed inlet of the second weighing hopper is disposed right below the discharge outlet of the first weighing hopper, and the feed inlet of the receiving box is disposed right below the discharge outlet of the second weighing hopper. A storage hopper feeding valve is arranged at the discharge outlet of the storage hopper, a connecting end of the storage hopper feeding valve is connected with a storage hopper feeding screw, and a connecting end of the storage hopper feeding screw is connected with an output shaft of a storage hopper feeding motor fixed to the frame. A first weighing hopper feeding valve is arranged at the discharge outlet of the first weighing hopper, and the first weighing hopper feeding valve is connected with a first weighing hopper feeding screw. The weighing device has a simple structure, can be used to weigh powder and powder particle mixtures for press-forming refractory bricks, and is higher in weighing accuracy. The weighing device is applicable to automatic transformation of the refractory brick production line. By adopting the device, the quality of products can be improved, and the working environment can be improved.

Description

technical field [0001] The invention relates to a weighing device used in the production and preparation process of refractory bricks in the iron and steel industry, in particular to a weighing device for refractory brick raw materials. Background technique [0002] Refractory bricks used in the iron and steel industry have a wide variety of raw materials, complex formulas, and large differences in density and specific gravity. To meet technical indicators such as product density, weight, and size, it is necessary to weigh the raw materials and then press them. At present, manual weighing is used. Heavy, labor-intensive, low efficiency, serious dust pollution. Most automatic production equipment at home and abroad adopt the volumetric method for weighing, which has large weighing errors and low precision. Because the raw material volume box is a part of the refractory brick mold, it is difficult to adjust the volume when the same mold produces products with different formula...

Heavy, high labor intensity, low efficiency, serious dust pollution

Most automatic production equipment at home and abroad adopt the volumetric method for weighing, which has large weighing errors and low precision. Since the raw material volume box is a part of the refractory brick mold, it is difficult to adjust the volume when the same mold produces products with different formulas, which is not suitable for multiple types of raw materials. weighing
