Definitions

  • the utility model relates to a device for fully dispersing and dissolving solid powders by using a liquid such as water, and is widely used in the fields of papermaking, water treatment, chemical industry and the like. Specifically, it is a dissolution apparatus using a one-stage or multi-stage guide tube type.
  • the conventional solid-liquid dissolving device employs a rotary agitator in a dissolving tank to achieve the purpose of dissolving the solid powder.
  • the disadvantages are as follows: 1. Due to the setting of the stirring device, the equipment volume is increased and the equipment cost is increased. 2. The mechanical agitating moving parts are more likely to be faulty; 3. The fixed stirring speed causes the operation flexibility to be lower; The mechanical shear-sensitive polymer has a large side effect of dissolution; 5. It is difficult to achieve multi-stage series use.
  • the utility model designs a first-stage or multi-stage guide tube type dissolution device, that is, 'there is a circular tube or a square tube-shaped guide tube in the dissolution tank, and is added at the bottom of the guide tube. Gas such as air.
  • the composition of the guide tube type dissolution device of the present design comprises: a dissolution tank (1), an air pump (2) externally disposed in the dissolution tank (1), and a guide tube (4, 9, 12) built in the dissolution tank (1). ), the airflow distributor (10, 11) at the bottom of the draft tube (4, 9, 12), the filter screen (13) above the dissolution tank (1), and the gas pipeline of the air pump (2) 3) Connected to the dissolution tank (1) and connected to the gas flow distributor (10, 11).
  • a guide tube can be arranged in the dissolution tank. It is also possible to connect a plurality of guide tubes in series in the dissolution tank, and to provide an overflow port on the partition between the guide tubes.
  • the gas pump continuously pumps the gas source into the guide tube in the dissolution tank through the gas pipeline, the addition of the gas causes a difference in the specific gravity of the solid-liquid mixture inside and outside the guide tube, and the jet action when the gas is added, so that the confirmation is confirmed.
  • the solid-liquid mixture circulates in accordance with the path set by the guide tube to achieve the purpose of rapidly dissolving the solid powder. Adjusting the flow rate of the gas makes it easy to adjust the circulation speed of the mixture.
  • the use of a plurality of flow-through type dissolution tanks in series allows the flow of the fluid to be closer to the flat flow to achieve full dissolution.

  • the solid powder (14) and the liquid (15) are fed into the dissolution tank from the upper part of the dissolution tank (1), and the gas pump (2) sends the gas into the guide tube through the gas pipeline (3) ( At the bottom of 4, 9, 12), the gas is evenly distributed through the airflow distributor (10, 11) and then enters the draft tube. Due to the different specific gravity of the mixture inside and outside the guide tube and the jet action when the air flow is added, the mixture flows from the outer guide tube at the bottom of the guide tube, and the mixture flows outward from the inside of the guide tube at the top of the guide tube. The circulation of the mixture.
  • an overflow port can be provided on the two-slot spacer or the two-strip spacer to achieve a series flow of the mixture.
  • the design has the following advantages: 1. Compared with the traditional built-in rotary agitator equipment, the design is small in size and low in cost; 2. The dissolving agitator is omitted; 3. The work is reliable and the equipment failure is small; 4. The operation flexibility is easy to adjust; 5. Due to the use of gas flow and specific gravity change as the cycle power, the influence on the dissolution of the mechanical shear sensitive polymer is small; 6. It is easy to realize multi-stage series use, and the dissolution effect is good.

Abstract

La présente invention a trait à une unité de dissolution comportant une enveloppe de guidage, plus particulièrement à une unité de dissolution pour la dispersion et la dissolution suffisantes de matière fine solide avec de l'eau ou autres liquides utilisant une ou des enveloppes de guidage en série. L'unité comporte un réservoir de dissolution, une pompe à l'extérieur du réservoir de dissolution, une enveloppe de guidage à l'intérieur du réservoir de dissolution, un distributeur de gaz sur le fond de l'enveloppe de guidage et une claie au-dessus du réservoir de dissolution. Une conduite de distribution d'air de la pompe relie le distributeur de gaz via le réservoir de dissolution. Une orifice de déversement est prévu sur la chicane de séparation entre les enveloppes de guidage. La vitesse de recirculation du mélange peut être réglée par l'ajustement du débit de gaz. L'unité de dissolution rend l'écoulement de fluide proche d'un écoulement à bouchons de sorte que le matière fine solide soit suffisamment dissoute. L'unité est d'utilisation fréquente dans les domaines de la fabrication de papier, de traitement des eaux et dans l'industrie chimique.
