Problems solved by technology

[0003] However, the stirring device of the traditional calorimeter will interfere with the heat measurement; the main influencing factors are: 1. The motor of the stirring device of the traditional calorimeter will generate a large amount of heat, and the motor will dissipate heat during the heat dissipation process. The heat is transferred to the water in the inner cylinder of the calorimeter through the stirring rod and the surrounding air; 2. The inner cylinder of the calorimeter is processed into an ellipse or a circle, and the volume of the inner cylinder is 2 liters. Generally, the water is only laminar flow, the heat convection between the bottom and the top is not obvious enough, and the time for the water temperature of the whole inner cylinder to reach uniformity is relatively long, because the stirring time required for the stirring device to stir and heat the water is relatively long, and also That is, the stirring efficiency is low, and a large stirring heat will be generated during the stirring process.

Abstract

The invention discloses a double-blade turbulent efficient stirring device for a calorimeter. The device comprises a motor, a coupling, a glass fiber stirring rod, a positive propeller stirring bladeand a reverse propeller stirring blade; a rotating shaft of the motor is connected with the glass fiber stirring rod by the coupling, and the positive propeller stirring blade and the reverse propeller stirring blade are mounted on the glass fiber stirring rod. The double-blade turbulent efficient stirring device for the calorimeter can reduce the stirring heat, improve the measurement accuracy ofthe calorimeter and avoid rocking and breakage of the stirring rod, and facilitates the assembly and disassembly of the stirring rod.

Description

technical field [0001] The invention relates to the technical field of coal quality analysis and detection equipment, in particular to a stirring device of a calorimeter. Background technique [0002] Calorimeter (Calorimeter), commonly known as calorimeter, domestic calorimeter, mainly measures the calorific value of coal, straw, petroleum and other solids, and can also measure the calorific value of liquids such as petroleum. It is mainly used in thermoelectricity, cement, coal, new energy and other fields. The motor of the traditional calorimeter stirring device is fixed on the opening cover of the instrument, and the stirring rod and blade fixed on the miniature bearing are driven to rotate through a rigid or winding coupling to achieve the purpose of stirring and uniform heating. [0003] However, the stirring device of the traditional calorimeter will interfere with the heat measurement; the main influencing factors are: 1. The motor of the stirring device of the trad...
