Description
Technical field
The utility model relates to filter, specifically a kind of portable pressure-reducing filter.
Background technology
Filtration under diminished pressure is the conventional filter method of laboratory and medication chemistry unit, utilizes vacuum or negative pressure suction to filter, and filters and has separating rate advantage faster than normal pressure, is particularly useful for the larger special circumstances of material viscosity to be separated.Current pressure-reducing filter common adapted glass water pump or electronic drawdown pump carry out negative pressure suction, but glass water pump easily broken, loss is large, water consumption is large, electronic drawdown pump volume is large, quality heavy, power consumption is large, and both all exist carrying, carry inconvenient problem.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the defect that above-mentioned prior art exists, provide one firmly, not cracky, and volume is little, quality is light portable pressure-reducing filter, be convenient to carrying, carry, also water and electric saving, energy-conserving and environment-protective.
For this reason, the technical solution adopted in the utility model is as follows: portable pressure-reducing filter, comprise side band air exhaust nozzle bottle,suction, be contained in bottle,suction top Buchner funnel, be placed in the filter paper in Buchner funnel, its technical characterictic is, it also comprises that the elasticity of a hollow and both ends open is by pressuring gasbag, one end of described air bag is connected on air exhaust nozzle by a flexible pipe, and the other end is provided with the first one-way ventilating assembly; The first described one-way ventilating assembly comprise hollow the first pedestal, be placed in taper the first jacking block in the first pedestal, the inner of described the first pedestal is placed in air bag and has the hole of running through for the little head end of the first jacking block, outer end evagination is in air bag, also laterally wears one and prevent first positive stop strip of the first jacking block from deviating from the first pedestal on outer end.
Press pressuring gasbag, the air in air bag outwards backs down the first jacking block and discharges (the first one-way ventilating assembly is opened) via the hole of the first pedestal; Unclamp after air bag, owing to being negative pressure state in air bag, the first jacking block resets and hole is blocked to (the first one-way ventilating assembly closure), and the air in bottle,suction is drawn in air bag by negative pressure through flexible pipe, has accelerated the speed of leaking under liquid in Buchner funnel.Air bag is rubber parts, and firmly, cracky not, and device overall volume is little, quality is light, is convenient to carrying, carries, in addition, and this structure water and electric saving, energy-conserving and environment-protective.
As improvement, the two ends of described the first positive stop strip all form the kink that is positioned at the external side of First.This setting, makes kink carry out horizontal direction to the first positive stop strip spacing, has avoided the first positive stop strip to skid off in the first pedestal.
As improvement, the air bag opening end being connected with flexible pipe is provided with the second one-way ventilating assembly, the second described one-way ventilating assembly comprise hollow the second pedestal, be placed in taper the second jacking block in the second pedestal, the outer end of described the second pedestal has the hole that the little head end for the second jacking block runs through, and innerly laterally wears one and prevents second positive stop strip of the second jacking block from deviating from the second pedestal.This setting, make when by pressuring gasbag, air in air bag is arranged toward balloon ends, the first jacking block is outwards backed down and discharge (the first one-way ventilating assembly is opened) via the hole of the first pedestal, the second jacking block is outwards backed down to the hole (the second one-way ventilating assembly closure) of blocking on the second pedestal, therefore, the air in air bag can only be discharged by the first one-way ventilating assembly, avoid air to enter bottle,suction by flexible pipe, affected the effect of negative pressure suction; Unclamp after air bag, owing to being negative pressure state in air bag, the first jacking block resets and hole is blocked to (the first one-way ventilating assembly closure), the second jacking block moves inward (the second one-way ventilating assembly is opened) because of the pressure differential inside and outside air bag, now the air in bottle,suction is drawn in air bag by negative pressure through flexible pipe, has accelerated the speed of leaking under liquid in Buchner funnel; Set up the second one-way ventilating assembly and avoided the impact on bottle,suction by pressuring gasbag, make the air one-way flow in bottle,suction, the better effects if of negative pressure suction.
As improvement, the two ends of described the second positive stop strip all form the kink that is positioned at the second pedestal outside.This setting, makes kink carry out horizontal direction to the second positive stop strip spacing, has avoided the second positive stop strip to skid off in the second pedestal.
As improvement, between flexible pipe and the air bag opening end that is attached thereto, be also connected with a bumping bag, one end of this bumping bag is enclosed within outside the openend of air bag, and the other end is enclosed within outside the end of flexible pipe.This setting, makes the bumping bag of setting up can effectively cushion the air spilling from the second one-way ventilating assembly, has avoided this part air to be directly punched into bottle,suction from flexible pipe.
As improvement, described air bag is fusiformis or spheroidal.This setting, makes the adhered shape hand shape of air bag, convenient operation.
As improvement, the bottom of described Buchner funnel is cylindric outlet, and this outlet is placed in bottle,suction, and the outer also cover of outlet has a rubber sleeve.This setting, makes good airproof performance between Buchner funnel and bottle,suction.
The beneficial effects of the utility model are mainly reflected in: the structure that glass water pump of the prior art, electronic drawdown pump is replaced with to rubber pneumatic bag and the cooperation of one-way ventilating assembly, make pressure-reducing filter firmly, cracky not, and volume is little, quality is light, be convenient to carrying, carry, also water and electric saving, energy-conserving and environment-protective.
