Embodiment 1

[0010] Embodiment 1: with reference to attached figure 1 . Fully automatic metal filter, the cylinder 4 and the cylinder upper cover 4-1 are connected by a cover lifting mechanism 1 and the cylinder upper cover 4-1 is equipped with a gas distributor 4-2, and the gas distributor 4-2 passes through the pipeline Connected with the nitrogen gas feed valve 5-4, the vibrating rod 2-1 of the pulse rapping device 2 is located inside the cylinder body 4, the rapping source 2-2 is located outside the cylinder body, and the distance between the upper ends of multiple metal filter screens 3 is suspended on the vibrating rod 2 -1 The liquid outlets at the upper and lower ends communicate with the liquid outlet pipe 5 located in the cylinder 4, and the liquid outlet of the liquid outlet pipe 5 communicates with the check valve 5-6 through the clear liquid valve 5-1; There is a slag discharge outlet 6 and its opening or closing is controlled by the electric slag discharge valve 7 located ou...

Embodiment 2

[0011] Embodiment 2: On the basis of Embodiment 1, the filtration method of the fully automatic metal filter, when the infusion pump inputs a certain amount and a certain pressure of the filtered material into the barrel 4, the liquid flows into multiple sheets under the action of pressure Metal filter screen 3, and multiple metal filter screens 3 produce a resistance to the flow of liquid, so the internal and external pressure difference is formed, so that the carbon powder and other substances in the filtrate outside the multiple metal filter screens 3 flow in with the filtrate, Gradually adsorbed on the surface of multiple metal filter screens 3, a filter layer with filtering ability is formed after passing through a large flow rate. After being collected, it flows out of the machine, and the filtrate is clear and transparent through the sight glass, and normal filtration can be performed. As the filtration progresses, more and more adsorbates will be absorbed by the multipl...

Abstract

The invention relates to a full-automatic metal filter and a filtering method adopting metal mesh fabrics as filtering components to separate solid and liquid in a sealed container. A barrel body and the upper cover of the barrel body are connected by a cover parting mechanism; an gas distributor is arranged in the upper cover of the barrel body and is communicated with a nitrogen swaging valve by a pipeline; a vibration rod of a pulse vibration device is positioned in the barrel body; the upper ends of a plurality of metal mesh fabrics are suspended at the liquid outlets of the upper end andthe lower end of the vibration rod at intervals and are communicated with an outlet pipe in the barrel body; the liquid outlet of the outlet pipe is communicated with an one-way valve by a liquid cleaning valve; the bottom part of the barrel body is provided with a deslagging outlet and is controlled to be opened or closed by an electric deslagging valve positioned outside a cone-shaped cavity; aliquid inlet is positioned at the lower part of the barrel body and is communicated with the barrel body by a liquid inlet valve; and a nitrogen pipe arranged in the barrel body and is communicated with the nitrogen swaging valve penetrating the barrel body valve. The invention has the advantages that firstly metal screens are utilized for filtering without the need of filtration fabrics, therefore, the metal filter has long service life; and secondly, solid and liquid separation can be carried out at severe conditions such as strong corrosion, high temperature and the like, the filter liquoris clear, and the moisture percentage of filter cake is low.

Description

technical field [0001] The invention relates to a fully automatic metal filter and a filtering method that uses metal mesh as a filter component for solid-liquid separation in a closed container. The filter is mainly used in petrochemical industry: polyvinyl alcohol, polyether, diesel oil, lubricating oil , white oil, transformer oil; mineral chemical industry and base oil: zinc oxide, titanium dioxide, dibutyl ester, dioctyl ester; oil: crude oil, drift oil, gasified oil, winterized oil, etc.; food: gelatin, salad oil, Starch, sugar juice, monosodium glutamate, milk, beer, etc.; pharmaceuticals: hydrogen peroxide, vitamin c, glycerin, etc.; coatings: varnish, resin paint, real lacquer, chemical fiber dyes, etc., which belong to the field of automatic metal filter manufacturing. Background technique [0002] The filtration process of the rectification section in the production process of calcium carbide polyvinyl alcohol (PVA) is a long-standing problem in the industry. Rec...
