Problems solved by technology

If there are materials to be crushed that are too long or too short in size, they will not be easily crushed, which will affect the crushing quality
At the same time, the pulverized powder is easy to accumulate and block the valleys of the rotary knife and the fixed knife, which affects the working efficiency

Embodiment 1

[0018] Such as Figure 1 to Figure 3 As shown, the anti-powder pulverizer includes a sealed pulverizing shell 1, a hammer frame 2, and a drive shaft 3. A plurality of racks 14 are arranged on the inner wall of the pulverizing shell 1, and one end of the drive shaft 3 passes through the The rear wall of the crushing shell 1 is set in the crushing shell 1, the hammer frame 2 is connected to the transmission shaft 3 and set in the crushing shell 1, and the hammer frame 2 is provided with a hammer fixing column 23 and the hairbrush fixing column 24, the hammer blade fixing column 23 is connected with a plurality of hammer blades 26 that can rotate along the axis of the hammer blade fixing column 23, and the hairbrush fixing column 24 is fixedly connected with a hair brush for preventing the rack 14 from accumulating powder. brush 25, the crushing shell 1 is provided with an air duct 17 in the area between its outer wall and the inner wall, and the inner wall of the crushing shell ...

Embodiment 2

[0021] This embodiment makes the following further limitations on the basis of Embodiment 1: the hammer frame 2 includes a front fixed plate 21 and a rear fixed plate 22, the two ends of the hammer fixed column 23 and the brush fixed column Both ends of 24 are connected with front fixed disk 21 and rear fixed disk 22 respectively. In this embodiment, in order to avoid the mutual influence between the hammer piece 26 and the brush handle during the crushing process, the hammer piece 26 can be arranged in the area between the front fixed disk 21 and the rear fixed disk 22, and the hairbrush handle can be arranged on the front fixed disk. Both sides of the disc 21 and the rear fixed disc 22.

Embodiment 3

[0023] In this embodiment, the following further limitations are made on the basis of Embodiment 2: the crushing shell 1 includes a cylinder 11 with openings at both front and rear ends; The rear cover 12 and the front cover 13 are fixedly connected to the front end of the cylinder body 11 and close the front end opening of the cylinder body 11 . In this embodiment, a rack 14 can be provided on the inner wall of the barrel 11 , the transmission shaft 3 can be installed inside the barrel 11 through the rear cover 12 , and the hammer holder 2 is also arranged inside the barrel 11 . In order to make the hammer 26 better cooperate with the rack 14 , the front fixed disk 21 can be arranged at the front opening of the cylinder 11 , and the rear fixed disk 22 can be arranged at the rear opening of the cylinder 11 . At this time, in order to ensure the feasibility of the rotation of the front fixed plate 21 and the rear fixed plate 22, the front cover 13 can be formed by the convexity...

Abstract

A disclosed powder-accumulation-preventing pulverizer comprises a sealed pulverizing shell, a hammer rack and a transmission shaft; the inner wall of the pulverizing shell is provided with multiple teeth bars; one end of the transmission shaft penetrates the back wall of the pulverizing shell and is arranged in the pulverizing shell; the hammer rack is connected to the transmission shaft and is arranged in the pulverizing shell, and is provided with a hammer fixing column and a hairbrush fixing column; the hammer fixing column is connected with multiple hammers capable of rotating along the hammer fixing column, and the hairbrush fixing column is fixedly connected with a hairbrush for preventing powder accumulation of the teeth bars; and an area between the outer wall and the inner wall of the pulverizing shell is provided with a vent pipe, and the inner wall of the pulverizing shell is provided with multiple vents communicated with the vent pipe. The powder-accumulation-preventing pulverizer overcomes the disadvantages of a conventional pharmaceutical pulverizer, and has the advantages of being good in pulverizing effect, capable of preventing powder accumulation, stead in operation, compact in structure and long in service life.

Description

technical field [0001] The invention relates to the field of pharmaceutical pulverizers, in particular to an anti-accumulation powder pulverizer. Background technique [0002] Crushing is an important process in the pharmaceutical industry, and pulverizers are also indispensable pharmaceutical tools. In order to obtain greater crushing capacity, pharmaceutical pulverizers are mostly provided with a rotary knife integrated with multiple blades in the pulverization chamber, and toothed fixed knives are provided on the inner wall of the pulverization chamber. Through these rotary knives and fixed knives The cooperation will crush the crushed objects put into the crushing chamber. Since the positions of the blades on the integral rotary knife are fixed, the cooperation between it and the fixed knife can only be applied to crushed materials of a specific size in order to achieve a good crushing effect. If there are crushed materials that are too long or too short to enter, they...
