Abstract

The utility model provides a liquid level automatic lifting controller which can simply and reliably adjust fiducial liquid levels and operating periods, comprising a water tank, a lever, a gate, a balance block, etc. Water flow which enters the water tank is controlled by an adjusting valve, and the operating periods can be adjusted. When the water tank is filled with water, the water tank sinks to drive the gate to lift to enhance the liquid levels; when the water tank sinks simultaneously, the bottom valve of the water tank is opened. When the water in the water tank is emptied, the water tank is lifted by the balance block again, and then the gate is reset. Only the water inlet and outlet valves of the water tank are adjusted well, and then the liquid level automatic lifting controller can automatically work.

Description

Liquid level automatic lifeing controller

The utility model is that a kind of mechanical liquid level promotes control device automatically.

Airfloat equipment and the waste-oil scavenger commonly used of water treatment both at home and abroad should improve liquid level and operate when deslagging or oil extraction at present, but this kind equipment of great majority does not have the liquid level lifting gear, i.e. liquid level is still the liquid level of usual work during deslagging oil extraction, influences treatment effect.Some factories also recognize this problem now, set up draining valve, make the water yield with artificial controlled and improve liquid level, though effect has raising, but require the operator to grasp accurately, otherwise liquid level is too high, conversely also impact effect, this method of operating requires workman's fixed cycle operator, has increased managerial personnel.

The purpose of this utility model is in order to reach automatically, regularly, quantitatively to improve liquid level and provide a kind of simple and reliable, the scalable benchmark liquid level and the liquid level in hoisting depth and operating cycle to promote control device automatically.

The technical solution of this device is to utilize leverage to promote or fall gate with the lifting liquid level, and the automatic control in the operating cycle of leverage is with the required time decision of water tank filled with water.Its work operation is to be that power is finished self to handle laggard weight of going into the water of water tank.Its working method accompanying drawings is as follows:

At air flotation slot, the water delivering orifice of degreasing tank, install this device additional, allow water outlet through tedge (5), gate (11) flows to vent pipe (4) and drains, by adjusting the tuning plate (10) of gate (11), can make the interior liquid level stabilizing of tank on the benchmark liquid level of usual work, at this moment sub-fraction water also bypass flow into water tank (6) by control valve (7), the outflow water yield of regulating and controlling valve (7) is with regard to the work period of the whole device of may command, be that control valve (7) is opened when big, the water that flows out is filled water tank (6) soon, device carries out work soon, otherwise control valve (7) is opened more after a little while, water tank (6) is just filled for a long time and is carried out work, when water tank (6) when filling water, and when surpassing the trimming moment of counterbalance weight (12), water tank just sinks and drives lever (8) and mentioned gate (11), the water level of discharge has been improved, make air supporting or waste-oil scavenger be in optimal liquid level and carry out deslagging oil extraction operation; When water tank (6) sinks, fixed water tank bottom valve core (3) highly by suspension rod and just broken away from water tank bottom valve (2), the current of water tank enter house steward through flexible pipe (1) and discharge together, water tank weight slowly alleviates, and when water is discharged to a certain degree, water tank moment is during less than the moment of counterbalance weight, water tank is just mentioned by lever, gate (11) returns on the usual working position just along with counterbalance weight descends together, and the liquid level of air flotation slot or degreasing tank is just fallen back on the liquid level of usual work.Because water tank has been enhanced, bottom valve core (3) under magneticaction, has clogged the bottom valve (2) of water tank again, and water tank is water storage again, and water carries out the work in cycle completely again by the time.

The technique effect of this device is a water tank (6) when obtaining the water of the enough weight that valve (7) flows out, and its action moment is greater than trimming moment, and water tank just sinks and drives gate (11) and improves and obtain the effect that in check liquid level improves.

Formation of this setting position and annexation are as shown, the two ends of lever (8) are respectively counterbalance weight (12) and water tank (6), the fulcrum (9) of lever (8) is fixed on the wallboard of tedge (5), gate (11) is connected the side of lever (8) by counterbalance weight (12) by connecting rod, and tuning plate (10) is installed on the gate (11) with the Luo select; Water tank bottom valve core (3) is that the garden conical surface contacts with bottom valve (2), reaches certain seal degree.

Claims

1, a liquid level promotes control device automatically, be to constitute, it is characterized in that by tedge (5), gate (11), tuning plate (10), drainpipe (4), water tank (6), water tank bottom valve (2), spool (3), flexible pipe (1), variable valve (7), lever (8), balance pivot (9) and counterbalance weight (12):

A, water tank (6) and counterbalance weight (12) are hung in the two ends of lever (8) respectively, and gate (1) is positioned at counterbalance weight (12) one sides;

The raising of B, liquid level is to realize by the raising that water tank (6) and lever (8) drive gate (11);

The power of C, raising gate (11) is from the weight of water tank (6) from the water of variable valve (7) acquisition;

The length of D, work period is by the size of variable valve (7) control aquifer yield;

E, control liquid level are controlled tank drains amount size by the size in the draining aperture of water tank bottom valve (2) and are realized in the time of high-level line length;

F, water tank bottom valve core (3) are to be made by magnetic material, are that the garden conical surface contacts with bottom valve (2).
