Description

Technical Field

[0001] The utility model belongs to the technical field of precision metering devices, and in particular relates to a precision metering device for catalyst configuration. Background Art

[0002] A catalyst generally refers to a substance that increases the reaction rate without changing the total standard Gibbs free energy of the reaction. It can also be described as a substance that can increase the chemical reaction rate without changing the chemical equilibrium in a chemical reaction, and whose quality and chemical properties do not change before and after the chemical reaction. According to statistics, more than 90% of industrial processes use catalysts, such as chemical, petrochemical, biochemical, environmental protection, etc. There are many types of catalysts, which can be divided into liquid catalysts and solid catalysts according to their state; they can be divided into homogeneous catalysts and heterogeneous catalysts according to the phase state of the reaction system. Homogeneous catalysts include acids, bases, soluble transition metal compounds and peroxide catalysts. Catalysts occupy an extremely important position in the modern chemical industry.

[0003] When accurately measuring the catalyst, a loss-in-weight scale is usually used. A loss-in-weight scale is a weighing device that provides intermittent feeding and continuous discharging. Since the loss-in-weight control is performed in the hopper, a higher control accuracy can be achieved, and the structure is easy to seal. Therefore, it is a great improvement in powder control compared to a spiral scale. The discharging screw machine or electric vibrator is controlled according to the rate of decrease of the weight of the material in the weighing hopper to achieve the purpose of quantitative feeding, that is, a loss-in-weight scale. When the material in the weighing hopper reaches the lower limit of the weighing, the discharging screw machine fixes the discharge amount according to the speed at that time, and at the same time controls the material in the silo to quickly go down into the weighing hopper. When the material is loaded to the upper limit of the weighing, the loading is stopped. Rapid loading can shorten the feeding time and improve the accuracy of weighing and the control precision.

[0004] However, when using a loss-in-weight scale to weigh powdered materials, the material enters the discharge bin through the discharge pipe during the feeding process and is then discharged through the bottom of the discharge bin. A large amount of dust is easily generated in this process, and the dust is easily dispersed into the air, causing material waste and polluting the surrounding air. Some dust remains in the inner cavity of the discharge bin, and when the material taking device is removed, it gradually disperses and falls, causing environmental pollution. In order to prevent dust from escaping during discharging, a catalyst configuration precision metering device is provided. Utility Model Content
