Abstract
The invention relates to a filtrate discharge device of a pressure filter. The filtrate discharge device can separate free flow and subterranean flow on a filter board for control, filtrate discharge of a single block of a filter plate can be effectively controlled, when the filter plate or the filter cloth is damaged, filtrate turbidity phenomenon is generated, a filtering channel for the filtrate discharge surface should be closed, so that the turbid filtrate cannot be discharged outside of the pressure filter, under prerequisite that the filtrate discharge speed is guaranteed, material loss is greatly reduced, the solid containing rate of the filtrate is reduced, work efficiency is increased, and the position of the damaged filter cloth is conveniently and rapidly detected.
Description
Technical field
The present invention relates to a kind of filter press filtrate tapping equipment.
Background technology
Common pressure filter draining mode is generally divided into the discharge opeing simultaneously of free flow, undercurrent and light and shade stream.Free flow refers to the mode that filtrate is expelled directly out from filter plate side；Undercurrent refers to that filtrate is pooled in the passage being made up of polylith filter plate corner apertures the mode of uniform effluent afterwards；The discharge opeing simultaneously of light and shade stream is the draining mode taking into account free flow and undercurrent.
During free flow discharge opeing, filter plate can not set corner apertures, and free flow discharging tube leads directly to undercurrent collection pore-forming, and filtrate discharge order is: discharge opeing face---liquid outlet---undercurrent collection pore-forming---free flow pipe, whole equipment only has free flow discharge opeing, its vertical pipe determines the need for according to actual needs install valve.
Mostly directly being blocked by free flow mouth during undercurrent discharge opeing, such filtrate discharge order is:---liquid outlet---undercurrent collection pore-forming---corner apertures is discharged in the undercurrent pipe that whole filtrates are made up of corner apertures in discharge opeing face.
Both install discharging tube additional in filter plate side during the discharge opeing simultaneously of light and shade stream, install again undercurrent discharging tube additional, discharge opeing order is: discharge opeing face---liquid outlet---undercurrent collection pore-forming---corner apertures and the discharge opeing simultaneously of free flow pipe.
Above-mentioned three kinds of equal Shortcomings of draining mode, as during only with free flow or undercurrent, can cause the phenomenons such as slow, the work holdup of filtration initial stage filtrate discharge speed；According to undercurrent discharge opeing or the discharge opeing simultaneously of light and shade stream, cause filtrate muddy if certain one or a few filter plate or filter cloth then can be caused to damage, then all filtrate will become cloudy, and causes serious material leakage, filtrate solid content high, i.e. runs Heisui River phenomenon.
On the other hand, owing to a pressure filter contains tens pieces of the most up to a hundred pieces of filter plates, operator nurse several even tens pressure filter often, when one or a few filter cloth of a certain pressure filter damages, operator judge have filter cloth or spoiled filter plate simply by whether running Heisui River, but cannot accurately judge specifically damaged which block, therefore, if the filtrate discharge of this filter plate can be found in time in pressure-filtering process and close, then can reduce race material, reduce filtrate solid content, labelling effect can be played again, there is provided convenient for follow-up repair and maintenance, time-consuming, improve efficiency.
Therefore, filter press filtrate discharge should take into account mass rate of emission and filtrate solid content two aspect, incidentally alleviates maintenance difficulty, improves maintenance work efficiency.
Summary of the invention
In place of the present invention is for overcoming above-mentioned the deficiencies in the prior art, provide a kind of filter press filtrate tapping equipment, described a kind of filter press filtrate tapping equipment includes free flow switch valve, free flow discharging tube, corner apertures, filter plate sealing surface, discharge opeing face, liquid outlet, undercurrent collection pore-forming, discharging tube plug, free flow collection pore-forming, discharging tube support, undercurrent discharging tube and undercurrent switch valve, it is characterized in that, free flow switch valve is installed in one end of free flow discharging tube, the other end installs discharging tube plug, at adfluxion pore-forming enlightened on the tube wall of discharging tube plug, free flow discharging tube can be inserted into or rotates in undercurrent collection pore-forming.
Free flow on one piece of filter plate and undercurrent are separated control by this device, can effectively control the filtrate discharge of monolithic filter plate, once occur filter plate or filter cloth to damage, cause the phenomenon that filtrate is muddy, only need to close the filtration channel in this plate discharge opeing face, can ensure that the filtrate of muddiness will not be discharged outside pressure filter, achieve on the premise of ensureing drain age velocity, greatly reduce loss of material, reduce filtrate solid content, improve work efficiency, also allow for afterwards quickly detection simultaneously and damage the position of filter cloth.

Embodiment
Install a moveable free flow discharging tube 2 containing discharging tube support 10 in filter plate side, switch valve 1 is installed in one end of free flow discharging tube 2, and the other end installs discharging tube plug 8, enlightened adfluxion pore-forming 9 on the tube wall close to discharging tube plug 8.When normal filter pressing (such as Fig. 1), open free flow switch valve 1 and undercurrent switch valve 12, filtrate 5 is pooled to liquid outlet 6 from discharge opeing face, flow into afterwards in undercurrent collection pore-forming 7, flow in corner apertures 3 again, a part is discharged by the undercurrent switch valve 12 on undercurrent discharging tube 11, and another part is by flowing out in the free flow liquid collecting hole 9 free flow switch valve 1 from free flow discharging tube 2；When this discharging tube runs Heisui River, free flow discharging tube 2 is inserted or screw in undercurrent collection pore-forming 7, make discharging tube plug 8 can block undercurrent collection pore-forming 7, and then guarantee that the black liquor in discharge opeing face 5 may not flow in corner apertures 3, and free flow discharging tube 2 is owing to there being free flow collection pore-forming 9, can still be used for discharges the filtrate of other discharge opeing surface current warps in corner apertures, therefore, can continue normally to use.It addition, to the full undercurrent discharge opeing realizing pressure filter, then need to close free flow switch valve 1, filtrate is all pooled in corner apertures 3, undercurrent discharging tube 11 discharges；To realize pressure filter full free flow discharge opeing, then need close undercurrent switch valve 12, filtrate is all discharged by free flow discharging tube 2.
