Impact powder-grinding and insect-killing machine with water-cooling function

Abstract

The invention discloses an impact powder-grinding and insect-killing machine with a water-cooling function, and the machine comprises a seat and a motor, wherein a support frame is fixedly connected to the seat, a shell is fixedly connected to the support frame, a discharge port is arranged on the sidewall of the shell, a rotor component is arranged in the shell, and a stator component is fixedly connected to the shell; the rotor component comprises a rotor disc and a rotor pin, and the stator component comprises a shell cover plate; the rotor component is provided with a radiating device, the radiating device of the rotor component comprises a hollow spindle, the middle of the hollow spindle penetrates through the shell and the shell cover plate, and the both ends of the hollow spindle are installed on the seat; the part of the hollow spindle located in the shell is fixedly connected with a connection disc, and the rotor disc is fixedly connected to the connection disc; and a spindle water inlet tube and a spindle water outlet tube are connected at the both ends of the hollow spindle respectively, and the motor is in transmission connection with the hollow spindle. According to the invention, comprehensive measures such as water-cooling and the like are adopted, so that the radiating effect is greatly improved than before, the quality of products in a grain production line is obviously improved, the edible quality of the finished products is obviously improved, and the service lives of the spindle and a motor bearing are prolonged exponentially.

Description

technical field [0001] The invention relates to an impact mill and an impact insecticide, which are mainly used in the wheat flour milling industry to crush the relatively pure endosperm after cleaning, peeling and germination into wheat flour, which can be used to kill the finished flour by impacting The pests and insect eggs existing in the flour can also be used to crush grains such as corn and rice and other solid granular materials. Background technique [0002] Pulverizing equipment called impact mills are widely used in the wheat milling industry. The impact mill consists of a casing, a rotor part, a stator part and a motor. Among them, the rotor component includes a rotor wheel housing, on which a disc-shaped rotor disc is fixedly connected, and at least 3 turns of rotor pins are installed on the rotor disc. The cross section of the rotor pins is square, and the number of rotor pins is usually At least dozens (total not less than 50). The rotor hub, the rotor disk...

AI Technical Summary

Problems solved by technology

Due to the wind force driven by the high-speed rotating runner and the impact force of the tubular pin, the material particles in the runner always have a considerable circular motion speed, so the relative speed at the moment when the tubular pin hits the material particle and the tubular pin hit the material particle The strength of the impact is greatly reduced, so the existing impact insecticide impacts the material particles and has the advantages of being able to partially kill the pests and eggs contained in the material, the temperature rise of the material after the impact is low, and there is no side effect; but the low impact intensity also leads to its insecticidal effect. Ineffective

In addition, the existing impact insecticides have no conveying function, so most of them need to be used in positive pressure conveying systems with Roots blowers, etc.

Due to the high price and high energy consumption of Roots blowers, high pressure and high-speed operation often lead to oil seal failure, which in turn leads to frequent accidents of motor bearing damage

Therefore, a comprehensive analysis of the existing impact insecticide has the disadvantages of poor insecticidal effect, large investment, high energy consumption and high accident rate.
