Abstract
The utility model relates to a hermetic filtering machine, particularly the improvement of a manual control pneumatic slag discharging system of a filtration machine. The utility model is characterized in that the bottom of the filtration machine is provided with an emptying valve; an air source valve is arranged in an adjacent form with the emptying valve; the air source valve and the emptying valve are formed into synchronous opening and closing through mechanical connection. Thus, when the air source valve is opened, the emptying valve on the filtration machine is synchronously opened. The filtration machine firstly obtains pressure discharging and waste liquids and /or gases in the filtration machine are emptyed before a slag discharging system is started. Thereby, the utility model can guarantee the filtration machine not to have pressure when slag of the filtration machine is discharged. Besides, the utility model can not bring liquids or gases spray so as to realize safe slag discharging.
Description
Technical field
Utility model relates to a kind of airtight filter, especially about the improvement to filter hand operated pneumatic dreg removing system.
Background technology
Airtight filter needs to get rid of on the filter inner filter element and adhere to filter residue, so that filter element obtains filter capacity again after filtration is a certain amount of.Existing filter slag-draining device is because of the filter working environment, common more employing hand operated pneumatic deslagging, promptly when the needs deslagging by manual unlocking cylinder steam supply valve, thereby make cylinder operation, open the movable deslagging bottom or the deslagging butterfly valve deslagging of filter bottom.After yet filtration is finished, often retain in the filter a small amount of filter liquide or gas are arranged, throw open deslagging bottom or residual cake valve deslagging, memory pressure can cause remaining liquid or gas to spray and casualty accident takes place, sometimes also can damage surrounding devices, therefore present slag-draining device deslagging is safety inadequately, and still having is worth improved place.
Summary of the invention
The purpose of utility model is to overcome the deficiency of above-mentioned prior art, and provide a kind of and can effectively guarantee deslagging safety, and simple in structure, good reliability, the airtight filter that cost is low.
The utility model purpose realizes that main the improvement is to set up a manual atmospheric valve in the filter bottom, and filter source of the gas valve is arranged on the atmospheric valve adjacent, and two valves realize that by mechanical connection synchronous interaction opens and closes.When opening the source of the gas valve, open atmospheric valve so synchronously, release is also discharged small amount of liquid or the gas that remains, make when opening deslagging bottom or residual cake valve not have pressure and do not have remaining liq and/or gas owing to shifting to an earlier date emptying in the filter, thereby reach the no pressure slag of safety.Specifically, the airtight filter of utility model, the filtration body that comprises built-in filter element, the bottom deslagging is with pneumatic keying activity bottom or pneumatic operated valve, manual source of the gas valve and deslagging cylinder valve, it is characterized in that said filter bottom is provided with atmospheric valve, the adjacent setting of said source of the gas valve with atmospheric valve, two valves form synchronous opening/closing by mechanical connection.
The said filter of utility model bottom is provided with atmospheric valve, and its effect is remaining small amount of liquid and/or a gas in the first emptying filter before deslagging is opened, and makes when deslagging is opened the interior no pressure of filter and do not have remaining liq and/or gas.It can be atmospheric valve to be set directly at filter the fuselage lower bottom part; Also can be to draw blow-down pipe, atmospheric valve is arranged on the blow-down pipe at the filter lower bottom part; Can also be that atmospheric valve is arranged on the movable bottom.
Said atmospheric valve of utility model and source of the gas valve for helping the convenient interlock that realizes, better are to adopt manual rotary valve or stroke valve, and be wherein suitable to rotate ball valve especially, conveniently opening and closing simple in structure.
Utility model is owing to have additional atmospheric valve at the filter lower bottom part, and form synchronous interaction with manual source of the gas valve, atmospheric valve was opened simultaneously when the source of the gas valve was opened like this, make that filter at first obtains release and emptying internal memory raffinate and/or gas before opening deslagging, thereby no pressure in the filter when guaranteeing deslagging, just can not cause liquid or gas to spray yet, realize safe deslagging.In addition, atmospheric valve shifts to an earlier date emptying, also helps the collection of filter liquide, and not only production environment safety, cleaning, and recyclable filtered fluid help economizing on resources.Adopt hand-operated valve to realize interlock, functional reliability is good, also helps and avoids only relying on that electric interlock control brings is big such as manufacturing cost, appliance working, sensor be easy to failure, the high deficiency of fault rate.
Below in conjunction with two non-limiting embodiment, further specify the utility model structure.
Description of drawings
Fig. 1 is the utility model first example structure schematic diagram
Fig. 2 is the utility model second example structure schematic diagram.
The specific embodiment
Embodiment 1: referring to Fig. 1.The airtight filter 6 of utility model, bottom have the movable bottom 7 of cylinder 5 fast-open types, and cylinder opens and closes by manual air valve 4 controls.Filter the fuselage lower bottom part and be provided with rotation emptying ball valve 1, rotate the 2 adjacent settings with the emptying ball valve of source of the gas ball valve, two valve handlers fuse by mechanical linkage 3, reach two valves and open and close simultaneously.
Embodiment 2: referring to Fig. 2, as embodiment 1, filter bottom deslagging is an air cylinder driven deslagging butterfly valve 8.
The said airtight filter of utility model comprises that closed shell includes the various filters of filter element, for example board-like airtight filter, the airtight filter of blade, the airtight filter of filter core etc.
Claims (3)
1, a kind of airtight filter, the filtration body that comprises built-in filter element, the bottom deslagging is with pneumatic keying activity bottom or pneumatic operated valve, manual source of the gas valve and deslagging cylinder valve, it is characterized in that said filter bottom is provided with atmospheric valve, the adjacent setting with atmospheric valve of said source of the gas valve, two valves form synchronous opening/closing by mechanical connection.
2,, it is characterized in that said atmospheric valve is arranged on the filter body according to the described airtight filter of claim 1.
3,, it is characterized in that said atmospheric valve and source of the gas valve are for rotating ball valve according to claim 1 or 2 described airtight filters.
