Problems solved by technology

[0004] like figure 1 The water vapor extraction mechanism of a common granulator is shown in the figure. The water vapor outside the ring die passes through the steam exhaust hole 2 on the protective cover 1, as shown in figure 1 As shown by the middle arrow, the water vapor in the protective cover 1 and outside the ring die 3 is discharged in the way of straight discharge or pumping, while the water vapor in the ring die 3 can only be discharged in reverse through the feed channel 4, so the reverse discharge Water vapor will seriously hinder the feeding of raw materials, and even cause "blockage" failure

Embodiment 1

[0019] Such as figure 2 As shown, this embodiment discloses a water vapor exhausting mechanism inside the ring die of the granulator. It includes a granulation chamber 30 of the granulator surrounded by a transmission disc 10 and a cylindrical ring die 20, which is used to provide a working space for the granulation process of the granulator. The end of the granulation chamber 30 communicates with the feed channel 40 of the granulator, and the granulated material enters the granulation chamber 30 through the feed channel 40 . A pressing roller assembly 50 is arranged at the axis of the transmission disc 10 , that is, the pressing roller assembly 50 is arranged in the granulating chamber 30 , and after the material enters the granulating chamber 30 , it is pressed into granules by the pressing roller assembly 50 .

[0020] During the granulation process, due to the friction between the material and the mold, the pressure roller assembly 50 and the ring die 20, a large amount ...

Abstract

The invention relates to the technical field of granulators, and particularly relates to an inner water vapor pumping drainage mechanism of a granulator circular mold. The inner water vapor pumping drainage mechanism comprises a granulating chamber formed by encircling of a transmission disc and a cylindrical circular mold, the end part of the granulating chamber is communicated with a feeding passage of the granulator, and the granulating chamber is covered with a protection cover; a vapor passage communicated with the protection cover is arranged between the granulating chamber and the feeding passage; and an exhaust opening is formed in the protection cover. The invention aims at providing an inner water vapor pumping drainage mechanism of the granulator circular mold. According to the technical scheme, a vapor forced discharging passage is additionally arranged in a door cover to achieve an effect of forcedly discharging hot vapor inside the circular mold, so that the impact of the water vapor on the material when the water vapor is reversely discharged from the feeding passage can be reduced.

Description

technical field [0001] The invention relates to the technical field of granulators, in particular to a water vapor extraction mechanism inside a ring die of a granulator. Background technique [0002] A granulator is a machine that uses the swinging action of a rotating drum to grind wet powder raw materials into granules through a wire sieve. The granulator is mainly composed of feeding, stirring, granulating, transmission and lubrication systems, etc. It is widely used in the pharmaceutical, chemical and food industries. Its working process is to enter the compound powder from the hopper into the feeding channel, adjust the speed of the stepless speed regulating motor to obtain a suitable material flow rate, then enter the agitator, stir and mix with steam through the stirring rod for conditioning, and finally enter the pressing chamber Perform granulation. [0003] During the normal production of the ring die granulator, the material enters the granulation chamber throu...
