Embodiment 1

[0029] Embodiment one, such as Figure 5 , 6 Shown, anti-scaling body comprises anti-scaling sheet 18, and described anti-scaling sheet 18 is circular cake, is provided with central hole 19 at the center of anti-scaling sheet 18, is provided with filter hole 20 around central hole 19, The axis of the central hole 19 is perpendicular to the end face of the anti-scaling sheet 18, the axis of the water filter hole 20 is at an angle of 90° to the end face of the anti-scaling sheet 18, and all the anti-scaling sheets 18 are set on the screw rod 21 through the central hole 19, adjacent to each other. The two anti-scaling sheets 18 are separated by a spacer 22, and are screwed and fixed by nuts 23. The anti-scaling sheet 18 is placed in the tube body 9, and the gap between the anti-scaling sheet 18 and the tube body 9 fits.

Embodiment 2

[0030] Embodiment two, the difference between this embodiment and embodiment one is that the anti-scaling body is a granular filter material, and the inner wall of the opening end of the anti-scaling pipe body 9 is fixedly covered with a ring 25, and the outer diameter of the ring 25 is the same as that of the pipe. Body 9 inner diameters are the same, as Figure 7 , 8 As shown, the end of the ring 25 facing the open end of the pipe body 9 is provided with a ring groove, and a filter screen 24 is placed on the ring groove, and a snap ring 26 is provided on the filter screen 24, and the snap ring 26 is closely matched with the ring 25, and the filter screen 24 is fixed on the ring 25. The filter screen 24 and the pipe body 9 form a chamber, and the filter material is placed in the chamber, and the filter material is evenly distributed in the pipe body 9, so that the maximum area can be in contact with water, so as to better prevent scale and scale. The mesh number of the filt...

Abstract

The invention discloses a front water purification scale preventer which comprises a shell with an upper opening and a lower opening, a scale preventing tube arranged inside the shell, a tube connector arranged at the upper end of the shell and a water discharge connector arranged at the lower end of the shell, wherein the scale preventing tube comprises a tube body and a filtering net; one end of the tube body is a sealed end; the sealed end faces to the water discharge connector; the other end of the tube body is an opened end; the opened end faces to the tube connector; the outer wall of the tube body is hollowed; the filtering net is arranged on the outer wall of the hollow tube body in a sleeved mode; and a scale preventing body is arranged inside the tube body. The front water purification scale preventer adopts complete physical type scale prevention, is free of toxicity or smell, is safe and environment-friendly, free of any chemical agent, free of maintenance and needs no extra power. Equipment pipelines can be prevented from being scaled, and at the same time impurities such as sand and rust in water can be filtered, so that the purpose of purification is achieved. The sewage discharge structure of the scale preventer needs no special tool, and the filtered impurities can be flushed out by only opening a valve at the bottom, so that the scale preventer does not need to be disassembled and is convenient to use.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a front water purifier and antiscale device. Background technique [0002] Fouling is a widespread problem in systems involving fluid transfer and circulation in petroleum, thermoelectric and other industrial and civil applications. In the field of water treatment technology, the precipitated water-insoluble sediments are generally regarded as scale, the most common of which is CaCO 3 and MgCO 3 . The scaling reaction of calcium carbonate is mainly due to the combination of calcium ions and carbonate ions or bicarbonate ions. If the positive charge of metal ions or the negative charge of acid radical ions can be neutralized by certain technical means, the combination rate of anions and cations will be greatly reduced, thereby significantly reducing the scaling rate. The electromagnetic field treatment method consumes a lot of power and cannot meet the requirements of ...
