Problems solved by technology

However, due to the internal structure and working principle of the forced feeder, it is difficult to have a reliable detection element that can adapt to this working condition.
Looking at all the material level detection components used in this type of equipment at home and abroad, they are basically in a disabled state, and in the end they can only rely on manual speed regulation and quantitative feeding to maintain a relatively stable material level.

Embodiment Construction

[0012] Control attached figure 1 , its structure is to include the material level automatic constant pipe 3, the forced feeder 5 and the roller extrusion granulator 6, wherein the automatic material level constant pipe 3 is inserted into the forced feeder hopper 4 of the forced feeder 5 from the top The required depth inside is fixed, and the automatic constant pipe 3 of material level is inserted into the hopper of the forced feeder from the top of the device, and the depth of its insertion is 5%-30% of the height of the hopper of the forced feeder. Forced feeder 5 links to each other with the roller extrusion granulator 6 that is installed below it. There is no need for intermediate silos and dosing devices as well as material level detection devices. Utilizing the characteristics of unidirectional pressure transmission of solid powder, through the material level automatic constant tube 3 at the feed inlet, the material level in the hopper 4 of the forced feeder is kept con...

Abstract

The invention relates to a double-roller type extruding and granulation device and granulation process flow thereof. The device adopts the structure that a material level automatic constant pipe is inserted to the required depth in the hopper of a forced feeding machine and fixed, and the forced feeding machine is connected with a double-roller type extruding and granulator which is installed below the forced feeding machine. An intermediate bunker, a quantitative feeding device and a material level detecting device are not required. The device has the advantages that the property of unidirectional pressure transmission of solid powder is utilized, and the material level in the hopper of the forced feeding machine is ensured to be constant and always in optimum operating state through the material level automatic constant pipe in the position of a material inlet, therefore the stable performance of the double-roller type extruding and granulator is ensured. The problems that the traditional forced feeding machine detects the material level state by adopting a material level meter and realizes the constant material level in the hopper of the forced feeding machine by the complex way of adjusting the quantitative feeding device are avoided, the intermediate bunker, the quantitative feeding device, the level detecting device and the like required by the traditional way are omitted, the height of the factory building and the investment are greatly reduced, and the reliability is high.

Description

technical field [0001] The invention relates to a double-roll extrusion granulation device with a forced feeder with an automatic and constant material level function and a granulation process flow. It belongs to the technical field of granulators. Background technique [0002] The traditional forced feeding machine adjusts the speed of the upstream feeding device by detecting the upper and lower material levels, so as to achieve the purpose of relatively stable material level in the forced feeding machine. However, due to the internal structure and working principle of the forced feeder, it is difficult to have a reliable detection element that can adapt to this working condition. Looking at all the material level detection components used in this type of equipment at home and abroad, they are basically in a disabled state, and in the end they can only rely on manual speed regulation and quantitative feeding to maintain a relatively stable material level.
