Embodiment 1

[0020] An improved crushing device for pharmaceutical intermediates, comprising a crushing cylinder, a crushing chamber 1 is arranged in the crushing cylinder, a rotating rod 2 driven by a motor is arranged in the crushing chamber 1, and a plurality of moving blades 3 are arranged on the rotating rod 2, A plurality of fixed blades 4 are arranged on the inner wall of the crushing chamber 1, and a plurality of movable blades 3 and a plurality of fixed blades 4 are disposed oppositely. The crushing chamber 1 is provided with a cooling water channel 6 along the direction of its outer wall, the inlet end of the cooling water channel 6 is arranged on the outer wall of the crushing cylinder, and the cooling water channel 6 continues to extend downward along the direction of the outer wall of the first outlet channel, extending to Near the end of the first outlet channel, it extends laterally to the outer wall of the crushing cylinder.

[0021] The implementation of the present invent...

Embodiment 2

[0023] A plurality of baffle plates 7 are arranged in the first outlet channel, and the plurality of baffle plates 7 are arranged in a zigzag shape in the first outlet channel, and each baffle plate 7 is provided with a discharge hole 8 . If there is no blocking of the baffle plate 7, the pharmaceutical intermediate powder will quickly reach the bottom under the action of gravity. Although there will be cooling water in the cooling water channel 6 to help it cool down, the cooling effect is not sufficient. In the present invention, the conveying channel of the pharmaceutical intermediate powder is extended in the first outlet channel, so that it can be fully cooled on the baffle plate 7 .

[0024] Each baffle plate 7 is a hollow structure and communicates with the cooling water channel 6 . In order to fully cool down the intermediate pharmaceutical powder, the baffle plate 7 can also be set as a hollow structure, allowing the cooling water in the cooling water channel 6 to ent...

Embodiment 3

[0026] A screen 5 is provided at the bottom of the crushing chamber 1 . The setting of the sieve 5 can obtain the pharmaceutical intermediate powder with a suitable particle size. Pharmaceutical intermediate powders with different particle sizes can be obtained according to actual needs.

[0027] Grinding protrusions are arranged on the inner wall of the crushing chamber 1 . The setting of the grinding protrusion can help the powder to be further rubbed and ground on it to improve the pulverization function.

Abstract

The invention discloses an improved crushing device for pharmaceutical intermediates, which comprises a crushing cylinder, a crushing chamber is arranged in the crushing cylinder, a rotating rod driven by a motor is arranged in the crushing chamber, and a plurality of moving blades are arranged on the rotating rod to crush A plurality of fixed blades are arranged on the inner wall of the cavity, and a plurality of movable blades and a plurality of fixed blades are arranged opposite to each other. The bottom of the crushing chamber is provided with a first outlet channel, which communicates with the crushing chamber, and the crushing chamber is opened along the direction of its outer wall. There is a cooling water channel, the inlet end of the cooling water channel is set on the outer wall of the crushing cylinder, and the cooling water channel continues to extend downward along the direction of the outer wall of the first outlet channel until it is close to the end of the first outlet channel, extending laterally To crush the outer wall of the cylinder. The invention has a simple structure and can be applied to the crushing of various pharmaceutical intermediates.

Description

technical field [0001] The invention relates to the field of crushing mechanisms, in particular to an improved pharmaceutical intermediate crushing device. Background technique [0002] Crushing equipment is the general term for crushing machinery and grinding machinery. The two are usually roughly distinguished according to the size of the discharge particle size: those with a particle size greater than 3 mm in the discharge account for more than 50% of the total discharge volume are called crushing machines; those with a particle size less than 3 mm account for more than 50% of the total discharge volume Those who are called grinding machinery. Sometimes grinding machinery is also called crushing machinery, which is the narrow meaning of crushing equipment. A machine that uses mechanical force to crush solid materials into small pieces, fine powder or powder. The characteristics of using crushing machinery for crushing operations are high energy consumption, high consum...
