Description

(54) MIXER OF VOLUMES OF LIQUID

t

The invention relates to the field of metering and proportional mixing of volumetric quantities of liquid and can be used in various industries in operations related to transport and storage of oil and oil products, with vehicle refueling, etc.

A device for chlorinating water is known using a plunger dispenser for a chlorine solution and a counter for the amount of water flowing through the pipeline, in which, for the simultaneous dosing of the solution and mixing it with water, the agitator / rotation is set in the pipe-15 wire and is rotated by the energy of the water flow. and driving the plunger metering device and the counter 1.

A disadvantage of this device is that the accuracy of proportional mixing of chlorine in the basic liquid is not ensured.

The most significant block of the technical essence of the present invention is a liquid volume mixer containing a volume counter of the main fluid, a multi-way control valve, a pump of a filler fluid with a power drive and a source of pressure 2. 30

The disadvantage of this mixer is that since the adjustment of the mixing ratio, carried out with the help of throttling devices, is performed discretely only during the calibration process, with a certain viscosity of the filler fluid, when the viscosity changes during operation, the accuracy of proportional mixing will deteriorate. The accuracy of the mixing of the liquid due to the inevitable obliteration and clogging of the throttling devices passing through will also deteriorate, which will cause the consumption of filler liquid to vary independently of the flow rate of the main liquid.

The purpose of the invention is to improve the accuracy of the proportional smegeaine base fluid with the additive.

The goal is achieved by the fact that the filler fluid supply pump is made in the form of a two-chamber piston pump, the actuator in the form of a piston engine, the rod of which is connected to the pump rod, and the piston chambers are connected to a pressure source through a spool device, the redistribution unit of which is kinematically connected with the moving part of the bulk counter of the main liquid. FIG. 1 shows the scheme of the proposed device; in fig. 2, 3 and 4 are diagrams of his work in different positions of the handle. The mixer (Fig. 1) contains a volumetric counter 1 of the main fluid, the movable part 2 of which is kinematically connected with the redistribution node 3 of the spool device 4 controlling the operation of the piston engine 5. The control valve has a plug 7 of the redistribution of the incoming filler fluid through channels 8 and 9 of the two-chamber piston pump Yu, connected by a branched channel 11 with a capacity of 12 filler liquids. The channel 13 connects the cavities of the pump 10 through a control valve b to the capacity of the filler fluid. The channels 14 and 15 connect the spool 4 to the power piston engine 5 of the pump 10. The channel 16 serves to supply compressed air to the spool 4. The channel 17 connects the spool to the atmosphere. Channel 18 connects control valve b with cavity 19 in front of counter 1. The device operates as follows. The main fluid enters the volume counter 1, the moving parts of which are driven by rotation of the distributor unit 3 of the spool 4, which drives the piston engine 5.. When the handle O is positioned (Fig. 1), corresponding to the measurement of the main fluid only, the position of the control valve plug 7 b is such that channels 8, 9 and 13 are communicated and channel 18 is blocked. At the same time, the pumped fluid is pumped out of the tank 12 through channels 11, 8, 9 and 13 back into the tank 12. If in the two-chamber piston pump 10 the volume of one of the chambers B is half the volume of the other chamber Au is equal to the minimum value of the specified percentage ratio of the additive to the main fluid, then when the handle is positioned. , 1 (Fig. 2) The appropriate percentage ratio of filler fluid to the main tube 7 position 0.1 crane b provides a control message channels 8 s13i9s18. The chamber S of the pump pumps the additive fluid from the tank 12 through the channels 11, 9 and 18 into the cavity in front of the counter 1, and the second chamber A of the pump through the channels 11/8 and 13 pumps the additive fluid from the tank 12 back to the same container. When the position of the handle is O, 2 (Fig. 3), corresponding to the percentage ratio of the filler fluid to the primary 0.2%, the position of the plug 7 of the control valve b ensures communication of the channels 9c13 and 8c18. The pump chamber A pumps the additive fluid from the tank 12 through the channels 11, 8 and 18 into the cavity in front of the counter 1. At the same time, the pump chamber B through the channels 11, 9 and 13 pumps the additive fluid from the tank 12 back into the same container. When the handle is in the position O, 3 (Fig. 4), corresponding to the percentage ratio of the filler fluid to the main 0.3%, the position of the plug 7 of the control valve b ensures communication between the channels 8, 9 and 18. Channel 13 is closed by plug 7. In this In this case, both chambers A and B of the pump pump the additive fluid from tank 12 through channels 11, 8, 9 and 18 in. the cavity in front of the counter, ensuring the total capacity of both chambers of the pump is 0.3%. At all four positions of the handle, the compressed gas enters channel 16 into the spool 4, the redistribution unit 3 of which alternately connects channels 16 with 15 or 14 and 17 with 15 or 14. Alternately, the compressed gas cavity piston engine S, puts the latter in motion and thus. Provides a dual-chamber piston pump 10.
