Abstract

The utility model relates to a slurry filtered water discharge unit particularly a converter slurry filtered water discharge unit. The device is improved to a high level difference type discharge unit based on the original floating barrel type discharge unit. The device opens and closes the valve of a discharge pipe to discharge filtered water when the water pressure in the discharge pipe is stronger or smaller than the negative pressure of the vacuum pump of a filter. The device can continuously and automatically complete slurry filtered water discharging operation.

Description

Slurry filtered water discharge unit

The utility model relates to filtering slurry water tapping equipment, is specially a kind of converter mud filtered water discharge device.

Converter current filtering slurry water tapping equipment generally adopts the contained water of vavuum pump negative pressure filtration mud, and filtered water is drained with the float bowl-type tapping equipment.But this technology has such problem, because SEA LEVEL VARIATION causes that keg float acts frequently, adds sometimes and contains some mud in the filtered water in the operation, cause the keg float shaft portion to hang mud and block, make action dumb, influence normal running, increase maintenance time and expense.

The purpose of this utility model provide a kind of can be automatically continuous blow-down filtering slurry water tapping equipment reliably.

In order to achieve the above object, the utility model has adopted gas-water separation escaper main body to link to each other with the filtering slurry device by the side connecting piece, link to each other with vavuum pump with the top connecting piece, the bottom of moisture trap is provided with the high potential difference drainpipe, and its useful non-return valve in termination, bottom is the filtering slurry water tapping equipment of draining valve.

This device be utilize negative pressure when vavuum pump greater than drainpipe in during the pressure of desire draining, draining valve is in closed condition, carrying out along with the filtering slurry operation, the drainpipe middle water level constantly rises, water level in drainpipe rises to a certain height, during negative pressure that the pressure of its water is set greater than vavuum pump, draining valve is opened automatically, water in the pipe can discharge, when having arranged water, draining valve makes valve closing by the suction function in its gravity and the main body, and seals by connecing the Rubber washer that studs with on the face in the valve.When then the drainpipe middle water level not only constantly rises to certain altitude but also repeat Open valve, discharge water and the action of valve-off.

The length of high potential difference drainpipe covers the Dou iron of burn-oning generally at 5-7 rice outside water discharging valve, to play the effect that utilizes gravity to reach automatic-closing valve.

The utility model is because only need transform former float bowl-type tapping equipment, and the keg float of dismantling is loaded onto vertical long drainpipe in the bottom of dehydrator, and non-return valve is set up in its termination, bottom, so simple in structure; Simultaneously, closing with the opening water discharge valve is to be greater than or less than the negative pressure that vavuum pump sets by the pressure that SEA LEVEL VARIATION in the drainpipe causes to move, so, realized unattended discharging operation, and, stopped the generation of mechanical breakdowns such as stopping up and block owing to cancelled keg float.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing.

Fig. 1 is the utility model primary structure and duty rough schematic.

In the present embodiment, gas-water separation discharging main body 1 links to each other with the filtering slurry device by side connecting piece 2, and link to each other with vavuum pump by top connecting piece 3, high potential difference drainpipe 4 is established in the bottom, there is the non-return valve 5 that studs with rubber liner 7 on interior contact-making surface bottom at pipe 4, covers outside it and also is welded with Dou iron 6.When filtering slurry water passes through, under the effect of vavuum pump, be negative pressure in the main body 1, simultaneously under the effect of gravity, and make draining valve close sealing state for 5 one-tenth by rubber liner 7, when filtering slurry water enters in the main body 1 by managing 2 along the direction of arrow, wherein gas part enters pipe 3 and is taken away by vavuum pump along direction of arrow rising top, and water falls into the bottom along the direction of arrow and enters high potential difference adjutage 4, when the water level of pipe in 4 rises to its pressure greater than the setting negative pressure of vavuum pump, valve 5 is opened automatically, water in the pipe 4 is drained, when having arranged water, inner connecing under the gravity effect of valve 5 and the suction function in the main body 1 that face is lined with the rubber liner, valve is closed sealing state for 5 one-tenth, along with working on of filtering slurry device, valve 5 certain hour at interval repeats to open and close action, reaches filtering slurry water and reliably emits automatically and continuously.
