Description

A kind of suction filtration dilatation expansion tank

Technical field

The utility model relates to a kind of suction filtration dilatation expansion tank, increasing work efficiency, preventing filtrate emerging, protection air extracting pump, clean operation environment, improve safety factor for coordinating existing Suction filtration device.

Background technology

For realizing solid-liquid separation, improving the speed of filtration simultaneously, usually adopting suction filtration, that is, the mode of filtration under diminished pressure.At present, Suction filtration device is made up of filter (containing filter pad), bottle,suction, air extracting pump and corresponding adapting pipe usually.In suction filtration process, filtrate enters and deposits collection in bottle,suction, the bottle,suction limited volume of standard, when needs are with large water gaging cleaning filter residue, be easy to occur filtrate bottle,suction of emerging enter into air extracting pump, leak phenomenon around operational facilities, bring adverse effect to operation and suction filtration facility, simultaneously, because the volume ratio of bottle,suction is more limited, be unfavorable for mating multiple filter with single pump, single bottle,suction simultaneously, volume ratio also due to bottle,suction is more limited, the speed of exhaust is not easily steady, is easily taken out leakage by filter layer.

Summary of the invention

The technical problems to be solved in the utility model is: provide a kind of and can increase work efficiency in suction filtration process, prevent filtrate emerging, protection air extracting pump, clean operation environment, improve the suction filtration dilatation shock absorber of safety factor.

The technical solution of the utility model is: a kind of suction filtration dilatation expansion tank, comprise tank body, there is top cover tank body upper end, there is supporting leg lower end, much larger than bottle,suction volume, (bottle,suction here refers to normally used container in the existing experiment described in background technology to the volume of tank body, that is relatively existing bottle,suction, the volume of tank body is larger), tank body is disposed with drainage conduit from low to high according to nozzle position top mark height, liquid level indictor tube, suction filtering tube and extraction pipe, drainage conduit is provided with valve, and its caliber is greater than liquid level indictor tube and suction filtering tube and extraction pipe.In suction filtration system, extraction pipe is used for connecting (for the purpose of safer with air extracting pump, preferably retain a glass bottle,suction and be connected between extraction pipe and air extracting pump), suction filtering tube is used for connecting with filter, drainage conduit runs up to the filtrate of safety levels for releasing, top cover is convenient to dismantle and clean tank body with tank body closely sealed connection by bolt and seal ring.

As preferably embodiment, drainage conduit, liquid level indictor tube, suction filtering tube and extraction pipe are uniform along tank body circumference, namely from the overhead projector of tank body, said structure parts are along the circumferential uniform intervals distribution of tank body, such set-up mode is conducive to the whole machine balancing of tank structure, handled easily, avoids each functional component to concentrate on a region.

Suction filtering tube quantity is more than or equal to 1.The quantity of suction filtering tube connects the quantity of filter as required and arranges, thus realizes an air extracting pump, a dilatation expansion tank and a bottle,suction safely and smoothly can carry out filtration under diminished pressure to the material in multiple filter simultaneously.

In simple terms, the utility model forms like this: comprise tank body, extraction pipe, suction filtering tube, drainage conduit, liquid level indictor tube and top cover.

The utility model adds suction filtration dilatation expansion tank between air extracting pump and filter, the bottle,suction volume used due to the volume ratio normal experiment of dilatation expansion tank is much bigger, can actv. hold suction filtration produce filtrate, filtrate race is avoided to emit, also help make the air-flow in suction filtration and filter pad up and down between pressure reduction more steady, reduce the phenomenon of taking out leakage to occur, also be more convenient for realizing carrying out suction filtration to the material in several filters with an air extracting pump simultaneously simultaneously, reach the safety factor improving suction filtration, improve equipment use efficiency, simplification device, the effect of increasing work efficiency.

The utility model has following advantage: 1., due to the volume ratio bottle,suction of dilatation expansion tank much bigger, make suction filtration system can actv. hold suction filtration produce filtrate, avoid filtrate evaporating, emitting, dripping or leaking of liquid or gas; 2., due to the volume ratio bottle,suction of dilatation expansion tank much bigger, make the air-flow of suction filtration can be more steady, the change of pressure reduction up and down of filter pad be relatively more steady, reduces the generation of taking out Lou phenomenon; 3., due to one can be arranged to multiple suction filtering tube on tank body, each suction filtering tube at least can connect a filter, thus realize an air extracting pump, a dilatation expansion tank and a bottle,suction can carry out suction filtration to the material in multiple filter simultaneously; 4., in the suction filtration work that quantity is larger, after using dilatation expansion tank, the consumption of the facility such as air extracting pump, bottle,suction can be saved, simplify the operation, increase work efficiency, also save the floor area of equipment.

Detailed description of the invention

As shown in Figures 1 to 3, a kind of suction filtration dilatation expansion tank, with suction filtration system with the use of, comprise tank body 1, there is top cover 6 tank body 1 upper end, there is supporting leg lower end, the volume of tank body 1 is much larger than the volume of existing bottle,suction, tank body 1 is disposed with drainage conduit 4, liquid level indictor tube 5, suction filtering tube 3 and extraction pipe 2 from low to high according to nozzle position top mark height, drainage conduit 4 is provided with valve, and its caliber is greater than liquid level indictor tube 5 and suction filtering tube 3 and extraction pipe 2, drainage conduit 4, liquid level indictor tube 5, suction filtering tube 3 and extraction pipe 2 are along tank body 1 circumference uniform (as Fig. 2 and Fig. 3).First suction filtration system is assembled, the filter having padded filter pad is placed on support, the supporting leg of dilatation expansion tank can be placed on terrace, with pipe the closely sealed connection of suction filtering tube 3 on filter and dilatation expansion tank, with pipe, the inlet connection of drainage conduit 4 with sewer or liquid waste processing pond is connected, safer in order to ensure Suction filtration device, a common bottle,suction can be increased, namely with pipe by extraction pipe 2 and the closely sealed connection of bottle,suction, again with pipe by bottle,suction and the closely sealed connection of air extracting pump, air extracting pump is connected with the mains, shut the valve in drainage conduit 4, then suction filtration operation is carried out.In suction filtration process, filtrate is by entering in the tank body 1 of suction filtration dilatation expansion tank, is checked the hydrops liquid level in cell body 1 by liquid level indictor tube 5, and experiment terminates or when determining to need discharge, close air extracting pump, the valve opened in drainage conduit 4 carries out discharge.If make hydrops liquid level superelevation due to carelessness, the bottle,suction that hydrops will be introduced between air extracting pump and expansion tank from extraction pipe 2, because bottle,suction is white glass material, liquid is emitted obviously to be found at once, can stop immediately bleeding before hydrops enters into air extracting pump, avoid air extracting pump to receive infringement.
