Problems solved by technology

Depending on the arrangement of the compressed air nozzle in the spray container, the arching and residual positions of the material are also different, so that the material cannot be effectively and continuously dropped near the spray inlet
[0006] Third, the gas consumption is large, material arching and blockage occur frequently, and the continuity and uniform velocity of material dilute phase transportation are uncontrollable
Due to the large diameter and long distance between the material injection inlet and the compressed air nozzle, which are relatively fixed and cannot be adjusted, the air consumption is large, and there is no agitator to stir and fluidize the material in the injection container, so the material is easy to concentrate and deposit at the bottom of the injection container. , when the valve is opened, the compressed air drives a large amount of material to be transported by jetting instantaneously instead of continuous jetting at a uniform speed. The disadvantage is that the front is dense-phase transportation, and the air behind it does useless work. Insufficient or untimely replenishment, resulting in some materials remaining in the pipeline
In addition, for light-weight, high-water-content, and high-viscosity powder materials, since there is no agitation and fluidization by the agitator, the material is easy to arch in the spray container, and the material that can be sprayed is only limited to the material around the nozzle. The material at the arch cannot effectively fall to the injection area in time
Therefore, according to different material characteristics, different compressed air pressure, flow rate, time, distance between the nozzle and the material port, cross-sectional area of ​​the gas-material two-fluid in the Venturi injection, mechanical material stirring and fluidization, etc. are required for reasonable coordination. Traditional The injection device is not equipped with a relevant adjustable structure. In actual application, it is easy to cause the evil effect of front blockage and back residue, and it cannot realize continuous, uniform speed, non-residue and non-blocking intermittent injection delivery.

Abstract

The invention provides a vertical intermittent powder and particle material dilute phase jet conveying device. The vertical intermittent powder and particle material dilute phase jet conveying device comprises a storage hopper, wherein a discharging port in the lower end of the storage hopper is connected with the upper end of a sealing valve; the lower end of the sealing valve is connected with a jet tank; the jet tank is provided with an air inlet a used for being connected with a pressurization air source; the jet conveying device further comprises a jet piece arranged in the jet tank; fan blades are arranged on the side wall of the upper portion of the jet piece; the portion, provided with the fan blades, of the jet piece is rotationally clamped in a jet piece shell; the air inlet a is connected into the jet piece shell through a guide pipe; a jet opening is formed in the lower end of the jet piece; a channel communicating the interior of the jet piece shell with the jet opening is formed in the jet piece; the lower end of the jet piece faces the discharging port in the lower end of the jet tank and forms a Venturi structure; and a stirring piece is arranged on the side wall of the lower portion of the jet piece. By means of the jet conveying device, the anti-blocking, anti-arching and anti-residue capacity of material jet can be effectively enhanced, manual work is reduced, and the jet release efficiency of dilute phase materials is improved.

Description

technical field [0001] The invention relates to a vertical intermittent powder material dilute-phase injection conveying device, which belongs to the field of material dilute-phase injection devices. Background technique [0002] The existing powder material dilute-phase injection conveying device is prone to blockage, arching and residue during the material ejection conveying process. Frequent manual unblocking is required to solve difficult problems such as arching of heavy or light materials and material residue in the pipeline. , affecting the device's normal injection and release of dilute phase materials. [0003] After countless experiments, the traditional positive pressure series material intermittent injection conveying device, because the material is directly deposited in the injection container for pressurization, and then the valve is opened for pressure delivery, the following problems often occur: [0004] One, it is difficult to realize or even can not be tr...
