Detailed Description

The present invention will be further described with reference to the following detailed description, wherein the drawings are provided for illustrative purposes only and are not intended to be limiting; to better illustrate the embodiments of the present invention, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product; it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.

Example 1

The filtering container for filtering the filtrate after the Ru-Al material is washed with acid is provided, as shown in figure 1, figure 2 and figure 3, the filtering container comprises a container body 1 and a container cover 2, wherein a feeding pipe 11, a discharging pipe 12 and an exhaust pipe 13 are arranged on the container body 1, a filter bag 3 and a supporting filter screen plate 4 which is arranged at the bottom of the filter bag and plays a role of supporting the filter bag are arranged in the container body 1, a plurality of water permeable holes 41 are radially distributed on the supporting filter screen plate 4 at equal intervals, and a positioning assembly 5 is further arranged in the container body 1 for positioning and fixing the mouth of the filter bag 3. The filter liquor is introduced into the tank body through the inlet pipe 11 and enters the filter bag 3, the periphery of the filter bag 3 abandons a filter cylinder influencing the filter effect of the filter bag in the traditional filter tank, and the filter liquor entering the filter bag 3 can be filtered efficiently.

When the feed pipe 11 injects the filtrate, part of gas may be brought in, which may cause the internal pressure of the tank 1 to increase, and accelerate the filtration efficiency of the filtrate at the filter bag 3, and as the gas is continuously injected and accumulated, the internal pressure of the tank 1 may be too high, and the excessive gas accumulation is obviously unfavorable, so that the exhaust pipe 12 provided on the tank 1 may timely exhaust part of the gas, and avoid the gas accumulation to generate adverse effect.

The exhaust pipe 12 and the feeding pipe 11 are coaxially arranged, and the pipe axes of the exhaust pipe 12 and the feeding pipe 11 are positioned on the diameter line of the tank body 1.

As shown in fig. 3 and 4, the positioning assembly 5 comprises a support ring 51 arranged on the inner wall of the tank body 1 and a press ring 52 which is nested with the support ring and pressed on the support ring, and the mouth of the filter bag 3 is clamped between the support ring 51 and the press ring 52. Specifically, the support ring 51 is the vertical bending structure, the end 511 of bending of support ring is vertical upwards parallel with jar side wall, and the clamping ring 52 is the door-shaped structure that has recess 521, and the end 511 of bending of support ring then inlays and inserts in the recess 521 of clamping ring, and this kind of nested fit mode of support ring and clamping ring can carry out stable pressure clamp to the filter bag sack, and when needing to dismantle the filter bag and change, only need make the clamping ring lift can, the swift dismantlement and the installation of light realization filter bag.

In order to further ensure the positioning stability of the filter bag 3 in the working process, a pressing cylinder 6 can be arranged above the pressing ring 52, the pressing cylinder 6 is of a hollow cylindrical structure, the pressing cylinder 6 is pressed to contact with the pressing ring 52 and applies pressure to the pressing ring, so that the pressing ring 52 is tightly matched with the support ring 51, and the pressing cylinder 6 is provided with a through hole at the corresponding position of the feeding pipe 11 and the exhaust pipe 12 to avoid obstructing feeding and exhausting. Generally, the outer diameter of the press ring 52 is suitable for being matched with the inner diameter of the can body 1, the outer diameter of the press cylinder 6 is also matched with the inner diameter of the can body 1, and the wall thickness of the press cylinder 6 is generally required to be smaller than the distance between the outer diameter and the inner diameter of the press ring 52.

In order to improve the overall use convenience of the filtering device, the downward-pressing cylinder 6 can be welded on the tank cover 2, the height of the downward-pressing cylinder 6 is configured according to actual conditions as long as the lower end face of the downward-pressing cylinder can be in contact with the pressing ring 52, the supporting ring 51 is welded on the inner wall of the tank body 1, and of course, each part can also be directly formed integrally with the tank body/the tank cover and is not limited to be welded and fixed after being manufactured in a split mode. After the filter bag 3 is placed on the support ring 51 through flanging, the filter bag opening is clamped by matching the press ring 52 and the support ring 51, and then the tank cover 2 and the tank body 1 are pressed down in a matching mode, so that the press ring 52 and the support ring 51 can be used for ensuring stable positioning of the filter bag 3.

Generally speaking, the supporting filter screen plate 4 is also fixed on the inner wall of the tank body 1 in a welding mode, so that the filter bag can be prevented from inclining to the supporting filter screen plate due to uneven pressure in the filtering process, and the filtering process and the filtering effect are not influenced.

As shown in figure 1, a tank body 1 and a tank cover 2 are fastened through loose joint screws 7, four supporting legs 8 are welded at the bottom of the tank body 1, and a lifting handle 9 is welded on the upper surface of the tank cover 2 to assist opening and closing of the tank cover.

The working process of the filtering container comprises the following steps: place the filter bag on supporting filter screen board, the filter bag sack is arranged in and is established between support ring and the clamping ring, adjust the cover and cover cooperation well, it is internal and pressure on the clamping ring to push down the barrel and insert the jar this moment, make clamping ring and support ring compress tightly the filter bag sack, adopt loose joint screw with cover and jar body coupling, later can get into the filtration flow, filtrating gets into jar body and flows into the filter bag through the inlet pipe and accomplishes the filtration, filtrating after the filtration flows out and discharges through arranging the material pipe through supporting filter screen board, then discharge through the blast pipe after getting into jar body along with the partial gas of filtrating injection.

It should be understood that the above examples are only for clearly illustrating the technical solutions of the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments.
