Description

Air filter-pressing cauldron

The utility model relates to the filtering equipment in a kind of Separation of Solid and Liquid, and it is particularly related to a kind of air press filtration still for chemical industry, hydrometallurgy, environmental protection industry (epi) use.

Before the utility model proposes, what the Separation of Solid and Liquid pressurization was adopted is the corrosion-resistant compression pump made from various different materials, and it adopts the impeller that runs up to carry to increase pressure.For the hydrometallurgy industry, the medium that is transferred has the corrosivity of different performance, and contains the solid granule of high rigidity often, cause the heavy wear to equipment, equipment pressure reduces, serious leakage, seal is easier to be impaired, and production cost is improved.Though if adopt gear pump to solve sealing problem, more serious to the wearing and tearing of gear, cost is higher.The manufactured materials of aforesaid equipment costs an arm and a leg, the manufacturing process complexity, and equipment often is out of order and causes stopping production, the maintenance cost height of equipment, efficient is low, and energy consumption is big, and noise is big.

The purpose of this utility model is to propose a kind of disadvantage, technology air press filtration still simple, with low cost that overcomes prior art.

The purpose of this utility model can realize by following technical measures.

This air press filtration still, it includes kettle and plurality of conduits is formed, top at kettle, be provided with manhole, Pressure gauge and safety valve are installed on the top board of manhole, at the bottom of the capstan straight cutting still that connects on the pressurizing valve, the steam line that connects on the heating steam supply valve also inserts at the bottom of the still, the discharge pipe that connects on the bleeder valve is installed in the bottom of kettle, on the discharge end of bleeder valve pipeline, link to each other with compressed air piping by anti-blocking valve and extruding steam supply valve, compressed air piping links to each other with the top of kettle by circulating valve, another compressed air piping links to each other with feed pipe by anti-blocking valve, and feed pipe links to each other by the top of inlet valve with kettle, and urgent exhaust-valve and pipeline thereof are connected the upper left quarter of kettle, the liquid level meter is installed on the upright position of kettle, and driving wheel is installed in the bottom of kettle.

Principle of the present utility model is under the situation of the liquid of needs conveying is following at normal pressure (or pressurization) or gravity flow; in the injection kettle; compressed air is sent in the kettle; raising along with the kettle internal pressure; can be to the destination with the medium smooth delivery of power; even can regulate arbitrarily with the need; supply with and compressed-air actuatedly simultaneously the solid turbid media is carried out brute force and stir; avoided the precipitation clogging; also design the pressure indication that is necessary on the still; automatically protect and prevent devices such as liquid refluence; work because of air compressor machine can place free from corrosion environment, its is direct contact corrosion medium, thereby has avoided the various disadvantages of legacy equipment.

Fig. 2. the side sectional view of the utility model embodiment.

The utility model embodiment.Referring to Figure of description 1-2.This air press filtration still, it includes kettle and plurality of conduits is formed, it is characterized in that top at kettle 1, be provided with manhole 2, Pressure gauge 3 and safety valve 4 are installed on the top board of manhole 2, at the bottom of the capstan straight cutting still that connects on the pressurizing valve 10, the steam line that connects on the heating steam supply valve 14 also inserts at the bottom of the still, the discharge pipe that connects on the bleeder valve 7 is installed in the bottom of kettle 1, on the discharge end of bleeder valve 7 pipelines, link to each other with compressed air piping by anti-blocking valve and extruding steam supply valve 13, compressed air piping links to each other with the top of kettle 1 by circulating valve 11, another compressed air piping links to each other with feed pipe by anti-blocking valve 12, feed pipe links to each other by the top of inlet valve 6 with kettle 1, urgent exhaust-valve 5 and pipeline thereof are connected the upper left quarter of kettle 1, liquid level meter 9 is installed on the upright position of kettle 1, and driving wheel 8 is installed in the bottom of kettle 1.

The ore pulp that to treat press filtration separation (or the medium that transmits) adds from inlet valve 6, open urgent exhaust-valve 5, observe liquid level meter 9, after treating that liquid is filled with kettle, close inlet valve 6, open pressurizing valve 10, charge into compressed air, observe Pressure gauge 3, after reaching desired pressure, open bleeder valve 7 and carry the high pressure ore pulp, carry out press filtration and separate, after filter press is filled to plate and frame filter press, close pressurizing valve 10 and bleeder valve 7, open anti-blocking valve and extruding steam supply valve 13, charge into the compressed air filter cake to filter press and further push, to reduce the liquid content in the filter cake.After pressing dry, close anti-blocking valve and extruding steam supply valve 13, ON cycle valve 11 returns confession still compressed air for the lower equipment of other working pressure to former steam line, and to the filter press slag dumping, so that carry out the next round operation.

The utility model has following advantage compared with the prior art:

1. improve one times of operating pressure, operating efficiency is enhanced about more than once.

2. solved the problem that is difficult to carry out Separation of Solid and Liquid with resisting medium.

3. save electric energy more than 85 percent, manufacturing cost is saved more than 60 percent, and maintenance cost is saved more than 98 percent.

4. noiseless, no leakage improves more than 8 times service life.

5. cake moisture reduces more than 60 percent.
