PATENT OFFICE.

The present invention is a water purification device in which the Precipitant automatically adds to the raw water in precisely measured amounts with mediation two measuring containers provided with three-way taps, filling and emptying alternately are fed, the taps are controlled by a common two-part tilting device.

ίο A water purification devices of this and a similar type have already become known in several embodiments, including patents 59950, 83214, 92597 and II473 ⁸ . However, all these devices prove to be disadvantageous insofar as the various reactants are added to the water to be purified, albeit alternately at the same time in the same mixing container. For efficient and complete water purification, on the other hand, it is expedient to add the precipitating agents used to the raw water one after the other. This requirement is fully met by the present arrangement, in which, in addition to two measuring containers for one precipitating liquid, two further measuring containers controlled by a common tilting device for a second precipitating liquid are arranged, in such a way that the latter are only emptied when the first precipitating liquid has already acted on the raw water.

In the accompanying drawings, the water purification device is shown, and although show

Fig. Ι an overall view, partly in section,

Fig. 2 is a plan view of Fig. 1,

FIG. 3 shows a view of the four distributors and the tilting box controlling them in FIG larger scale and partly in section.

The uncleaned water flows through a Dehne's see float b or a similar device at a (Fig. 2), which keeps the water level in the clarification tank at a certain height. The water is heated as high as possible by means of a pipe preheater c using machine exhaust steam. On its way to the tilting box d, it feeds the lime saturator e. The water level in this is regulated by a float /. The unpurified water flowing in through the pipe g divides and on the one hand reaches the lime water saturator e, in which it ^{falls through the pipe e 1} to the bottom, causing the quick lime lying on the bottom of the kalk water saturator e to be swirled up and thus a complete saturation of the Inflow water is achieved. On the other hand, the uncleaned water flows through the pipe g ^l into the two-part tilting box d.

The saturated lime water generated in the lime water saturator e rises in this and reaches the two through the pipe h

Claims (1)

large distributors, the so-called lime water distributors ζ z ¹ (Fig ', ι, 2 and 3). The latter essentially consist of the three-way valve Z ₁ i'j, the valve z '., Z' ^1. , And the attachment z ₃ i ' ₃ , in which a float z ₄ z' _{4 is} installed (Fig. 3). The control of the two three-way cocks Z ₁ i \ bezAV. the two distributors ii ¹ for the purpose of alternating filling and emptying takes place in a known manner through the tipping box d, with the intermediary of the linkage kk ¹ . The supply of the saturated lime water from the saturator e to the distributors ii ¹ takes place through the pipe h, while the discharge "of the lime water in certain equal amounts from the distributors ii ^l through the pipe / or. / '. Due to the strong movement of the incoming water takes place in the dump body d is an intimate mixture of the raw water instead of the Kalkwasscr, whereby the transmutation of the double carbonate of lime, a is in carbonate of lime almost sudden. the now milky water pours through the to the box in connected pipe η (Fig. ι and 2) into waste tube 0. To d upon tilting of the box to avoid a violent whipping of the same to be on the outside of the box into two Luftpumpen_pj? ' (Fig. 1) arranged, which brake the movement of the tilting box d by means of cable transmission. In addition to the addition of lime water, the unpurified water also contains an addition of soda, and only after the bicarbonate of lime has been eliminated. The soda solution is prepared in the vessel q (Fig. Ι and 2). For this it passes through the pipe r to the two small, z'z below the distributors ^'1 arranged \ ^ erteilern ss ^l, which act in the same way as the Kalkverteiler zz' ¹ (Fig. 3) and also of the dump body of d being controlled. From the two distributors. ss ^l the soda solution passes alternately in equal, measured amounts through the pipe t at u into the waste pipe ο and combines in this with the water to be cleaned (Fig. i). After it has passed through the waste pipe ο, the water rises between the partitions ν (Fig. I) in the container w , where the movement of the water slows down considerably as a result of the larger cross-section. The water is further clarified by means of a coke or gravel filter. The purified water can be led through the pipe χ (Fig. 1 and 2) directly to the suction line of the feed pumps. The alternating withdrawal from the clarification basin is followed by the float b mentioned at the beginning and thus causes a faster or slower movement of the tilting box d.
