Problems solved by technology

However, due to the high requirements on material pressure in the drop molding process, it is difficult to accurately control the strict conditions in all aspects of large-scale production. Therefore, this method only stays in the laboratory test stage and cannot be produced on a large scale.
[0005] The large-scale molding technology of clay adsorption has always been the bottleneck that inhibits the widespread use of clay adsorbents, making it impossible for large-scale use of clay adsorbents with good adsorption performance, low price, and a wide range of sources

Embodiment Construction

[0030] In order to better understand the present invention, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0031] Such as figure 1 A water-phase clay adsorbent forming equipment shown includes a PVA hot-melt device 1 , a feed mixing device 2 , a forming device 3 , a solidifying device 4 and a material delivery pump 5 .

[0032] The PVA hot melting device 1 includes a constant temperature heating reaction cylinder 1-1, a feed inlet 1-2, a PVA agitator 1-3 and a PVA discharge pipe 1-4. Materials such as solid PVA, water and sodium alginate are added into the constant temperature heating reaction cylinder 1-1 through the feed port 1-2 in proportion. It starts to dissolve at 90°C, and the high temperature of 105±2°C can make the molten material boil slightly, and the stirring of PVA mixer 1-3 can make the PVA with larger particles dissolve quickly and fully; in order to prevent possible Incompletely...

Abstract

The invention discloses water phase clay adsorbent forming equipment suitable for the process using polyethylene glycol (PVA) to serve as a binding agent to form powdery clay. The equipment comprisesa PVA hot melting device, a feeding mixing device, a forming device, a solidifying device and a material conveying pump. The equipment enables powdery clay minerals to be formed into ball-shaped particles, serving as the adsorbent, on the appropriate condition, the ball-shaped particles will not be dispersed after being used and regenerated in water many times, the problem of volume production ofthe PVA powdery clay forming method is solved, the clay adsorbent can be produced and formed continuously on batches, by means of special design of the dripping forming equipment, the special designedmanner of multi-time mixing, uniform feeding and dripping forming is adopted, and the problems that during volume production, cavitation bubbles occur easily, and balls are different to form are solved.

Description

technical field [0001] The invention relates to a material processing device, in particular to a water-phase clay adsorbent forming equipment. Background technique [0002] Adsorption technology is widely used in sewage treatment. Clay minerals have good adsorption and ion exchange performance due to their unique layered structure, and have broad application prospects in wastewater treatment. Moreover, clay mineral adsorbents have a wide range of sources and low prices, and have always been considered as the most promising adsorbents. Clay minerals such as rectorite, montmorillonite, etc. have a powdery structure and need to be formed and placed in an adsorption tower before they can be used in water treatment projects. [0003] The clay mineral molding method is widely used for the molding of diatomite, using the agglomeration method, but the diatomite adsorbent formed by this method can only be used for the adsorption of air pollutants, and the adsorption will disperse wh...
