Technical Field

The utility model belongs to the technical field of the chemical industry equipment technique and specifically relates to a jar is filtered in high-efficient lab scale.

Background

In the development stage of the aqueous transparent ferric oxide, a certain amount of small samples need to be extracted to test various performance indexes of the product. The existing test sample extraction methods mainly comprise two types: one method adopts a filtering method, and specifically comprises the steps of pouring a synthesized small sample into a barrel, adding water, pouring clear water at the upper part of the barrel at regular intervals by utilizing self-precipitation of the pigment, and repeating the steps until the poured clear water is detected to be white-free by a barium chloride solution. Because the particle size of the water-based transparent iron oxide is smaller and the precipitation speed is slower, the adoption of the mode not only has extremely low efficiency, but also avoids pouring out part of the pigment along with clear water. The other mode is to pump-filter the synthesized aqueous transparent ferric oxide slurry by a vacuum pumping filtration method, the penetration is serious because the pigment particles are fine and particularly hydrophilic at the initial stage of the pumping filtration, the problems of difficult pumping filtration and difficult rinsing occur at the later stage of the pumping filtration, the slurry finally pumped and filtered only has a very thin layer, the pumping filtration can be completed only by dozens of times, and the efficiency is extremely low.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings.

According to the explanation of hydraulics: because water has viscosity, the water generates a velocity gradient in the flowing process, namely, a velocity change value exists between water layers. It is believed that the anisotropic coagulation is caused by Brownian motion, and the isotropic coagulation is caused by stirring. No matter stirring or folded plate reaction, grid reaction, labyrinth reaction and the like, no or no vortex is generated in water flow, and when the vortex exists, the speed gradient value is changed rapidly, so that not only mutual collision of aggregates is caused, but also 'spin' of the aggregates or micro-aggregates is generated.

The utility model discloses be based on above principle promptly, through making the vortex at the internal at jar for there is the speed difference value between the adjacent flow layer, a particle probably receives different speed influence in its direction of advance's both sides, is the difference formation moment at these two different speeds, promotes floc or condensate self rotation. Since the flocs are not ideal spheres but rather act like clouds and twigs, it can be stated with certainty that the radius of the flocs or agglomerates may be extended several times, or even higher, once they have rotated on themselves, and the flocs grow to a certain extent, i.e. detach from the body, down the wall.

Thus, flocculation is essentially completed in the very small bottom layer below the solid-liquid separation module.

As the first embodiment of the utility model, the flocculated particles formed by flocculation have increasingly higher density and smaller flow velocity in the process of continuously rising. The flocculated particles which slowly begin to settle can be impacted by the rising water flow of the slurry which is continuously poured into the tank bottom, when the gravity is equal to the upward impact force, the flocculation keeps dynamic and static, and then an active flocculated suspension layer is formed. The particles in the suspension layer are continuously increased due to the interception of impurities in the water, and the sedimentation rate of the flocculated particles is continuously improved, so that the rising flow rate and the water yield of the water flow can be improved.
