Quantitative uniform speed glue injection device

Abstract

The invention provides a uniform-speed quantitative glue injection apparatus. The apparatus comprises a glue storage pot and a glue supply pump; one end of the glue supply pump is connected to the glue storage pot through a glue discharge pipeline, and the other end is connected to a glue supply pipeline; the end of the glue supply pipeline is provided with a glue injection structure for injecting glue, and the glue supply pipeline is provided with a glue injection control valve for opening or closing the glue supply pipeline; a primary backflow pipeline is connected between the glue supply pipeline and the glue storage pot for backflow of glue materials in the glue supply pipeline to the glue storage pot, the primary backflow pipeline is provided with a primary backflow control valve for opening or closing a backflow pipeline, and the primary backflow control valve and the glue injection control valve are operated in alternative correlation. The uniform-speed quantitative glue injection apparatus is safe and intelligent, and the injected glue is uniform and controllable; pressure in liquid supply pipelines in the temporary state without glue injection and the state with glue injection are kept identical, so that waste of time and cost due to newly established pipeline pressure after pumping termination without glue injection is avoided.

Description

technical field [0001] The invention relates to the technical field of equipment for stirring and granulating powder materials, in particular to a quantitative uniform-speed glue injection device. Background technique [0002] Granulation is the operation of processing materials in the state of powder, molten liquid, aqueous solution, etc. into particles with a certain shape and size. Improve the fluidity, scattering, and adhesion of materials, and it is conducive to accurate measurement and protection of the production environment. [0003] In the process of wet granulation, it is necessary to add a certain amount of high-viscosity adhesive liquid to the powder raw material for granulation. In the prior art, artificial glue is usually used, and all the sol is added to the mixing device at one time and then stirred and granulated. , the particle size deviation of the obtained granulated particles is large, and the mixing uniformity is poor. The glue injection machine can b...

Problems solved by technology

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the glue injection machine in the prior art needs to re-establish the internal pressure of the liquid supply pipeline and increase the cost when the glue injection machine is restarted after the state of temporarily not adding glue, and the cost is increased, so as to provide a kind of safety intelligence, The glue injection is uniform and controllable, and the quantitative and uniform speed glue injection device can maintain the same internal pressure of the glue supply pipeline as the state of glue addition in the state of temporarily not adding glue
