Description
Technical Field
The invention belongs to the technical field of sewage treatment, and particularly relates to a water purifying device.
Background
As is well known, natural precipitation and lake and river water cannot be used for direct drinking or production, and because of various natural factors and human factors, the water contains various impurities, and direct drinking causes great harm to human health, various countries think of treating and disinfecting the water.
From the aspect of water supply treatment, impurities in the water body can be divided into three categories, namely suspended matters, colloids and dissolved matters. The water purification treatment of urban water plants aims to remove suspended substances, colloidal substances, bacteria and other harmful components which can bring harm to human health and industrial production in raw water bodies, so that purified water can meet the requirements of life drinking and industrial production.
Wherein the disinfection process does not completely destroy the microorganisms, but only requires the destruction of pathogenic microorganisms. Although most of bacteria and viruses can be removed from water through coagulation, sedimentation and filtration, the disinfection plays a role in ensuring that drinking water reaches the bacteriological index of drinking water, and simultaneously, the water keeps a certain residual chlorine amount at the tail end of the urban water pipe so as to control bacterial reproduction and prevent pollution. The chlorine adding amount (liquid chlorine) for disinfection is 1.0-2.5 g/m3In the meantime. Hypochlorous acid generated mainly by the reaction of chlorine gas and water acts as an oxidizing action inside bacteria, destroying the enzyme system of the bacteria and leading the bacteria to die. The sterilized water is lifted by the clean water tank through the water pump room to reach a certain water pressure, and then is delivered to thousands of households through the water delivery and distribution pipe network.
The disinfection tank is generally adopted in the existing disinfection equipment, and is communicated with the filter tank, so that the filtered water directly enters the disinfection tank, and then chlorine is introduced into the disinfection tank, thereby disinfecting the water. Such a disinfection apparatus has certain drawbacks: chlorine is directly introduced into static water, and the chlorine and the water in the disinfection tank cannot be fully mixed, so that the disinfection effect is poor.
Disclosure of Invention
The invention aims to provide a water purifying device which can fully mix chlorine and water and improve the disinfection effect.
In order to achieve the purpose, the invention provides the following technical scheme: the water purifying device comprises a support frame, a purified water bucket, an air blowing mechanism and a power mechanism for rotating the purified water bucket; the water purifying bucket is obliquely and rotatably arranged on the supporting frame, the high end of the water purifying bucket is provided with a water inlet, the low end of the water purifying bucket is provided with a water outlet, a plurality of water hoppers are arranged in the water purifying bucket, and the water hoppers are connected to the inner wall of the water purifying bucket to form a water hopper ring; the air blowing mechanism comprises an air blowing pipe and a water wheel, and the water wheel is fixed on the air blowing pipe; one end of the air blowing pipe is provided with an air inlet, the other end of the air blowing pipe extends into the purified water bucket, the air blowing pipe is rotatably connected with the purified water bucket, the center line of the air blowing pipe is superposed with the center line of the purified water bucket, and the air blowing pipe is provided with a plurality of air blowing holes; when the water purifying bucket rotates in the forward direction, the water wheel rotates in the reverse direction under the power of the water flowing out of the water bucket.
Compared with the disinfection tank structure in the prior art, the technical scheme has the following beneficial effects:

2. Make water wheels carry out rotation opposite with water purification bucket rotation direction through the water that flows from the water bucket to make the air drum also rotate, chlorine in the air drum can discharge faster under the effect of centrifugal force like this, has more chlorine promptly to get into the water purification bucket, and the disinfection effect is better, and the kinetic energy of this technical scheme utilize water ingeniously makes water wheels rotate, and need not additionally add power device.
3. Because the density of the chlorine is greater than that of the air, the chlorine which is not dissolved in the water falling from the water bucket can be gradually settled into the water at the bottom of the purified water bucket, the water in the purified water bucket is disinfected, and the disinfection effect is improved.
4. The water bucket can continuously and repeatedly scoop water and pour water through the continuous rotation of the water purifying barrel, so that the disinfection is more thorough; and because the purified water barrel rotates continuously, the water in the purified water barrel is in a moving state all the time, which is beneficial to improving the dissolution rate of chlorine dissolved in the water and has better disinfection effect.

Meanwhile, chlorine gas introduced into the large-diameter pipe 4 from the air inlet 40 enters the small-diameter pipe 5 and is discharged into the purified water bucket 2 from the air blowing hole 50, and tap water poured out of the water bucket 3 is disinfected; the shape of the water falling out of the water bucket 3 is similar to a waterfall shape, so that the contact area of chlorine and water is enlarged, and the chlorine can be dissolved in the water more fully in the process that the water in the water bucket 3 falls downwards; meanwhile, the water wheel 6 rotates to drive the small-diameter pipe 5 to rotate, so that chlorine in the small-diameter pipe 5 can be discharged more quickly under the action of centrifugal force, namely more chlorine enters the water purifying barrel 2, and the disinfection effect is better; the diameter of the large-diameter pipe 4 which is filled with the chlorine is larger than that of the small-diameter pipe 5, so that the air pressure in the large-diameter pipe 4 is larger than that in the small-diameter pipe 5, and the chlorine is discharged more quickly; along with the rotation of the purified water barrel 2, the disinfection process is continuously repeated, and the disinfection is more thorough. Particularly, because the density of the chlorine is greater than that of the air, the chlorine which is not dissolved in the water falling from the water bucket 3 can be gradually settled into the water at the bottom of the purified water bucket 2, and the disinfection effect is better; meanwhile, because the purified water barrel 2 is always in a rotating state, the water in the purified water barrel 2 is always in a moving state, which is beneficial to improving the dissolution rate of chlorine dissolved in water and has better disinfection effect. The sterilized water is discharged from the gap of the water outlet 21. Therefore, compared with the prior art, the technical scheme has better disinfection effect by introducing chlorine into static water.
The foregoing is merely an example of the present invention and common general knowledge of known specific structures and features of the embodiments is not described herein in any greater detail. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several changes and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
