(54) ВЕСОВОЕ УСТРОЙСТВО ДЛЯ ДОЗИРОВАНИЯ ЖИДКОСТИ(54) WEIGHT DEVICE FOR DOSING LIQUID

1one

Изобретение относитс к производству средств весового дозировани жидкостей и может быть использовано дл дозировани флотационных реагентов переменной плотности.The invention relates to the production of means for weight dosing of liquids and can be used for dosing of flotation reagents of variable density.

Известен автоматический дозатор дл порционного дозировани жидкости, соде1 жаший промежуточную емкость, соединенную с магистральным трубопроводом. Емкость снабжена на входе и выходе клапанами , управл емыми по сигналам, выдаваемым при замыкании цепи электромагнитаA known automatic dispenser for batch dosing of liquid, containing an intermediate tank connected to the main pipeline. The tank is equipped with inlet and outlet valves, controlled by signals issued when the electromagnet circuit is closed

ЫИзвестный дозатор может быть применен лишь дл объемного дозировани жид- кости.Known dispenser can only be used for volumetric dosing of liquids.

Известно также дооируютее устройство , содержащее весоизмеритель, св занный с дозирующей емкостью и с системой автоматического управлени выдачи дозы ЖИДКОСТИ .It is also known to provide a device containing a weighing device associated with a dosing tank and with a system for automatically controlling the delivery of a dose of LIQUID.

Однако известное устройство не обеспечивс1ет достатс)чной гомнсюти непр015ывного дозировани жидкости с прромеиной плотностью . Наиболее бли.чким по технической However, the known device does not provide sufficient availability of continuous dispensing of liquid with promein density. Most Brief

сущности к предлагаемому вл етс весовое устройство дл дозировани жидкости , содержащее взвешивающий мехат1зм, св занную с ним дозирующую емкость с игольчатым выпускным клапаном, управл емым след щей системой з.The essence of the invention is a weighing device for dispensing a liquid, containing a weighing mechanism, a metering container connected to it with a needle discharge valve, controlled by a follow-up system.

Известное устройство не обеспечивает непрерывного дозировани жидкости переменной плотности.The known device does not provide continuous dosing of a fluid of varying density.

Цель изобретени - повышение точности непрерывного дозировани жидкости с переменной плотностью.The purpose of the invention is to improve the accuracy of continuous dosing of fluid with variable density.

Дл этого расходна емкость выполнена с измен ющик с по высоте профилем и с расположенным вертикально по ее боковой поверхности щелевым сливным отверстием , причем профили расходной емкости и сливного отверсти вьшолнены по гиперболическому закону.For this purpose, the supply tank is made with a profile with a height along the profile and with a slotted drain hole located vertically along its side surface, and the profiles of the supply tank and the drain hole are hyperbolic.

Claims

The weighing device for dosirovanny liveability contains the supply tank 1 with ismon to cim at the height of the pr ("} | ily, on the sides of the surface of which a slit drain hole is made. The profiles of the feed container and the drain hole are hyperbolic. The capacity is related to the weight measurement 2 from the yoke 3, quadrant 5 with a load 6 and the electric tracking system 7, for example, a positional contact controller. Quadrant 5 is connected to the beam 3 by means of a flexible tape 4, the flow capacity 1 is suspended towards the opposite rocker arm 3. Track pa system 7 is electrically connected to the back-up mechanism M of the valve 8 installed on the inlet pipe. Quadrant 5 is made in the form of pganka 9 (see fig. 2) with lever 10 mounted on the prisms 11. On the bar there is a position sensor load 12 (for example, a PF type ferrodynamic converter) and reversible electric drive 13 (for example, an RD-O9 electric motor). On the lever 10 there is a load 6 of quadrant 5. The electric drive is connected to the load with a screw 14, and the rotary lever of the position sensor with the load the pros ki th e kosyn 15. Device performance is dependent on the position of the load 6 quadrant 5, which may vary automatically. The device works in the following way. If the device performance corresponds to the set one, then quadrant 5 is in a position where the contacts of the following electrical system 7 are open. In the case of measuring the plane (specific weight) of the solution or pressure in the supply pipeline, the equilibrium between the inflow of dilution and its flow the solution weight changes in the consumable capacity 1. In this case, quadrant 5 of the weight measuring mechanism 2 will tend to deviate from the equilibrium position and close one of the contacts boiling system 7, increasing or reducing the influx of solution into the container 1. By the measure will remain closed as long as not vernets quadrant 5 to its original position. For the directional change in the output of the device, an electric actuator 13 is used, which rotates the weight of quadrant 5 by rotating the screw 14. This also disrupts the system equilibrium and closes one of the contacts, increasing or decreasing the solution inflow into the container so that the system becomes equilibrium again. The profiled gusset 15 is moved along with the load. Its movement causes a deviation of the lever of the load position sensor 6, the output of which is fed to the secondary device or to the regulator input. A liquid weighing device comprising a supply tank connected to a weight meter, a main pipeline connected to the entrance of the supply tank through an adjustable valve associated with a control system, characterized in that in order to improve the accuracy of continuous dosing of variable density liquid The expendable capacitance is made with a profile varying in height and with a slit drain hole located vertically along its side surface. bones and a drain hole are made according to a hyperbolic law.
