MIX THE BLOW PUMP

The invention relates to a mixing pump, by means of which certain additives, such as soap solutions, emulsifiable oils, etc., can be mixed with e.g. water.

In currently used solutions, the emulsion is mixed into a storage tank, from where it is transferred under pressure to the application. Current methods cause problems with water contamination, mainly lime, which causes dirt on the sliding surfaces, filters and piping because lime waste settles from the emulsion in the storage tank and continues to migrate, causing a difference. Disadvantages. In addition, the emulsion is very sensitive to receiving and producing bacteria and yeasts in the storage tank, which disrupts the operation of the equipment. In addition, a mixing pump solution is known from Danish Publication No. 138277.

The mixing pump according to the invention provides a decisive improvement over the above drawbacks. The invention is characterized by what is stated in the claims.

The main advantage of the invention is that it is achieved; completely get rid of the storage of the mixed emulsion, and even water impurities do not cause problems when the water is transferred. . a membrane dispenser is used. a double-acting piston pump on the oil side provides precise concentration of the emulsion and stepless adjustment of the stroke length provides precise concentration control of the emulsion. Maintenance costs are saved and good operational reliability is achieved because the mixing pump is durable and simple.

In the following, the invention will be explained in more detail by means of the accompanying drawing, Fig. 1, which shows a schematic representation of the operation of the mixing pump.

The figure shows a diaphragm pump 4, 7,8,9 and a piston pump 6,12,14,15 mounted on the device body 11, with articulations 17 and 2 90408 connecting the arm 3.5. The oil to be mixed enters the piston pump via line (Ö) and leaves the piston pump via line 16. The water, in which case the oil is mixed, enters the diaphragm pump via two different pipelines (VI), (V2). From the diaphragm pump, the water passes two routes through either valve 1.1 or 1.2 to the emulsion line (E), to which the oil also enters along line 16. The supply of pressurized water to the diaphragm pump is controlled by valves 2.1 and 2.2. When the mixing pump is running, open valves 2.1 and 1.2.

The water then flows through the valve 2.1 into the chamber formed by the diaphragm pump half 4 and pushes the piston 7 and the diaphragm 8 towards the half 9, whereby water flows from the chamber formed by the half 9 through the valve 1.2 into the line (E). As the arms 3 and 5 then move to the right as shown in the figure, the piston pump simultaneously pumps oil by means of the piston 15 from the chamber 6 through the directional valve 13 to the line 16 and from there to the line (E). The piston pump chamber 14 draws in new oil through the directional valve 13 from the line (Ö). When the piston of the diaphragm pump has moved so far to the right that the extension of the arm 5 meets the right-hand motion limiter 10, the valves 2.1 and 1.2 are electrically closed. At the same time, valves 1.1 and 2.2 are opened. In this case, the water coming through the pressurized water line V2 presses the piston 7 of the diaphragm pump to the left and presses the water from the chamber formed by the half 4 into the line (E). Correspondingly, the piston pump now presses the oil from the chamber 14 to line 16 into the water line (E). This movement of the diaphragm pump is limited by a left-hand stop 10 which gives an impulse to change the functions of the valves in the water lines. The pumping energy of the mixing pump is obtained from the pressure energy of the water.

The adjustment of the oil volume with respect to the water flow is performed by moving the attachment point of the piston pump piston rod 12 on the arm 5. The attachment by means of the part 18 can be moved by the distance (S) on the arm 5. The adjustment changes the stroke length of the piston pump.
