Problems solved by technology

[0002] There are many forms of separation and filtration of solid impurities in liquids. At present, the common ones are pressurized plate and frame filtration, normal pressure gravity filtration and centrifugal filtration. Pressurized plate and frame filtration needs to consume a lot of power to generate a pressure difference on both sides of the filter medium. , and the filter residue will quickly deposit on the filter screen under the action of pressure. The filter screen needs to be disassembled and cleaned in time, which is time-consuming and laborious
The filtration speed of atmospheric gravity filtration is very slow, and there is also the phenomenon of filter residue deposition, and the cleaning of filter residue is also time-consuming and laborious
Centrifugal filtration needs to provide strong power, and it is only used for experimental research or small-volume applications, and it is difficult to promote it on a large scale

Embodiment 1

[0052] Such as figure 1 , figure 2 , image 3 , Image 6 , Figure 7 As shown, the outside of the mixed liquid barrel 13 is equipped with a purified liquid barrel 10 for containing pure liquid. The bottom plate of the purified liquid barrel 10 is installed on the upper part of the support 7, and the support 7 is located inside the collection barrel 5, which is a container with an upper opening.

[0053] The mixed liquid tank 13 is a vertically transparent structure, and the inner wall is equipped with a filter plate 12. The filter plate 12 divides the inner space of the mixed liquid tank into an upper purification area and a lower extension area. After the liquid is injected, the extension area below the filter plate 12 A closed air chamber 25 is formed between the upper part and the purified liquid barrel 10, and a plurality of inverted cone-shaped support holes 23 are arranged on the filter plate 12, and sinking balls 11 are installed in the inverted cone-shaped support ...

Embodiment 2

[0063] Such as Figure 8 As shown, the purified liquid barrel 10 is placed outside the mixed liquid barrel 13, and is connected with the mixed liquid barrel 13 through the connecting body 22. The sewage outlet is located at the bottom of the connecting body 22 and is coaxial with the axis of the mixed liquid barrel 13. The mixed liquid barrel 13 The bottom is installed on the support 7. All the other parts are the same as the first embodiment.

Embodiment 3

[0065] The positional relationship and setting method of the mixed liquid tank, the purified liquid tank, the collecting tank, the liquid inlet valve, the liquid discharge valve and the recoil valve in this embodiment are the same as those in the first embodiment, the difference is that there is no nut installed on the lower part of the filter plate, and there is no Set the axis.

[0066] Such as Figure 4 , Figure 5 , Image 6 , Figure 7 As shown, the sewage outlet is connected to the installation plug body 6, the upper end of the plug body 6 is connected to the first pull rope 20, the other end of the first pull rope 20 is connected to the part of the sinker ball 11 located below the inverted tapered support hole, and the sinker ball 11 is located in the inverted taper hole. The part above the tapered support hole is connected with the second stay rope 19, and the other end of the second stay rope 19 is connected with the floating ball 18 rising and falling with the liq...

Abstract

The invention discloses separation and purification equipment and a method. The separation and purification equipment comprises a mixed liquid drum, a purified liquid drum and a collection drum. The upper portion of the mixed liquid drum is open while the inner wall is fittingly provided with a filter plate, the filter plate is provided with a plurality of inverted conical supporting holes in which sinking balls are fittingly mounted, and the filter plate, except for the area of the inverted conical supporting holes, is provided with a plurality of filter holes. Side walls of the inverted conical supporting holes are provided with a plurality of filter holes as well. An extending portion of the mixed liquid drum is communicated with the purified liquid drum. After liquid injection, a hermetic air chamber is formed between the extending portion and the purified liquid drum, and the communication portion is provided with a sewage outlet which is fittingly connected with a plug. The collection drum externally sleeves the mixed liquid drum, the filter plate is fittingly connected with a rotating shaft, an ejector plate is arranged on the lower portion of the rotating shaft, and the mixed liquid drum is connected with a backflush valve. According to a communicator principle, filtration of impurities in liquid and washing of filter residues are realized by virtue of the pressure difference.
