Description

Technical Field

[0001] The invention relates to the technical field of tungsten steel blade processing, in particular to a heat treatment device for a pulverizer tungsten steel blade. Background Art

[0002] A pulverizer is a machine that crushes large-sized solid raw materials into required sizes. The pulverizer consists of coarse crushing, fine crushing, wind conveying and other devices. It achieves the purpose of the pulverizer in the form of high-speed impact, uses wind energy to pulverize in one go, and cancels the traditional screening process. It is mainly used in mining, building materials and other industries. A pulverizer is a machine that crushes large-sized solid raw materials into required sizes. According to the size of the crushed or crushed materials, the pulverizer can be divided into coarse crusher, pulverizer and ultrafine pulverizer. There are four types of external forces applied to the solid during the crushing process: shearing, impact, rolling and grinding. Shearing is mainly used in coarse crushing and crushing operations, and is suitable for crushing or crushing tough or fibrous materials and large blocks. Impact is mainly used in crushing operations and is suitable for brittle materials. Crushing, rolling is mainly used in high-fineness crushing operations, suitable for ultra-fine crushing of materials of most properties, grinding is mainly used for ultra-fine crushing or ultra-large crushing equipment, suitable for further crushing after crushing. The actual crushing process is often several external forces acting at the same time, but high-end crushers are tailored according to the crushing environment. Tungsten steel blades are made of tungsten steel, which is an alloy material made of hard compounds of refractory metals and bonding metals through powder metallurgy. Tungsten steel has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance, especially its high hardness and wear resistance, which remain basically unchanged even at a temperature of 500 degrees Celsius, and still have high hardness at 1,000 degrees Celsius.

[0003] For example, the patent document with the announcement number CN 112391520 A discloses a heat treatment process for tungsten steel blades for a crusher, which includes the following steps: 1) heating the formed tungsten steel blade to 630-670°C and keeping the heating state for 22-26h; 2) cooling the tungsten steel blade obtained in step 1) with the furnace, and when the temperature drops to 80-120°C, taking out the tungsten steel blade and cooling it naturally in the air to obtain a tungsten steel blade for a crusher, which has the advantage of being able to improve the toughness of the tungsten steel blade.

[0004] However, in the actual process, due to the limitation of its own structure, this structure can only carry out multiple calcination and hammering of a single tungsten steel blade raw material of the crusher. The repeated calcination and hammering of a single tungsten steel blade raw material will cause the calcination and hammering equipment of the equipment to have a long stagnation gap, and the equipment cannot quickly position and load the tungsten steel blade raw material, resulting in the overall heat treatment efficiency of the equipment for the tungsten steel blade raw material is low, and continuous and uninterrupted heat treatment operation cannot be achieved. At the same time, when the equipment is hammering the tungsten steel blade raw material multiple times, it is impossible to efficiently remove the flying chips during the hammering process, which affects the surrounding production environment and cannot meet daily use needs. Therefore, it is urgent to design a heat treatment device for tungsten steel blades of crushers to solve the above problems. Summary of the invention
