Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water purifier for removing impurities contained in tap water or well water to obtain clean water.

[0002]

2. Description of the Related Art Conventionally, in general households and restaurants, various types of water purifiers have been used to remove impurities contained in tap water and well water to obtain clean drinking water. Water purifiers range from simple structures that are attached to the faucet of the water supply to large-scale structures that temporarily store water in the tank for purification. There is a wide variety of methods ranging from the method of increasing the purity of water by performing electrochemical treatment.

One of the conditions of the water purifier is that it has an excellent water purifying ability, but since it is used every day, it is also important that the operation cost is low and the maintenance is easy. It is also extremely important that the chemical substances contained in the filter medium do not elute into the drinking water purified by the water purifier.

Therefore, recently, a water purifier using charcoal as a filter medium has been developed, which is cheaper than other filter mediums, has a strong adsorptive power, and is harmless to the human body. A water purifier using charcoal puts water and charcoal in a designated container and
The water is purified by allowing it to stand for a period of about day and night, and the clear water in the container is used as drinking water.

However, such a water purifier has a long time for water purification, and when a large amount of drinking water is required, not only a large container is required, but in some cases, It is very inconvenient because it may not be possible to deal with it without preparing multiple containers.

Therefore, as a device that can cope with such a situation, a charcoal water purifier and process are disclosed in Japanese Patent Laid-Open No. 7-
It is disclosed in Japanese Patent No. 328612.

[0007]

Since the water purifier disclosed in the above publications uses charcoal as an adsorbent,
Although there is no problem in terms of safety, the purification speed is slow because it is a batch processing method in which water is once stored in the water purifier body for purification.

Further, since the air is sent into the water stored in the water purifier body using an air pump, a power source is required for actual operation, and the structure is complicated.

Therefore, the problem to be solved by the present invention is to provide a water purification apparatus having a simple structure, excellent processing capacity, high safety of water purification, and easy maintenance.

[0010]

In order to solve the above-mentioned problems, a water purifying apparatus of the present invention has a tubular body whose end face is openably closed, charcoal filled inside the tubular body, and a side surface of the tubular body. It has a plurality of tubular bodies arranged in parallel with each other, a through hole that communicates the inside of the tubular body with the inside of the tubular body, and an opening for pipe connection formed in the tubular body.

Charcoal produced by steaming oak, oak, larch, etc. is used as a fuel and has excellent adsorbability because many fine voids are formed in the charcoal itself. Therefore, the water purifier of the present invention purifies water by allowing water to pass through a tubular body filled with charcoal and adsorbing impurities contained in the water to the charcoal to remove the impurities.

When water is fed into the tubular body through an opening formed in the tubular body on the side surface of the tubular body, the water moves in the tubular body and a through hole that connects the inside of the tubular body to the inside of the tubular body. To enter the inside of the tubular body. Water entering the tubular body moves while contacting with the charcoal filled in the tubular body. At this time, impurities contained in the water are adsorbed by the charcoal and gradually cleaned. . Then, the water purified inside the tubular body passes through the through hole communicating with the inside of the tubular body provided separately from the tubular body, enters the tubular body, and exits from the opening formed in the tubular body. .

As described above, in the water purifying apparatus of the present invention, water is not directly injected into the tubular body filled with charcoal but is injected through the tubular body and the through hole, and the purified water is also passed through the through hole. Also, the structure is such that it is discharged through the attached tubular body. Therefore, since the water injected into the tubular body and the charcoal can be kept in contact with each other for a long time, the adsorption effect of the charcoal can be utilized to the maximum and an excellent water purification effect can be obtained.

Further, by disposing a plurality of through holes that connect the inside of the tubular body and the inside of the tubular body in a dispersed manner,
Since the water is injected into the tubular body, the water is circulated inside the tubular body, and the water is discharged from the inside of the tubular body, the charcoal filled in the tubular body can be utilized evenly.

Further, since the end face of the tubular body is closed so as to be openable and closable, and there is no connecting portion with the water injection pipe or the water distribution pipe or other pipes near the end face, the end face can be easily opened. Therefore, cleaning of the inside of the tubular body and replacement of charcoal can be performed extremely easily.

Further, the water purifier of the present invention is characterized in that the charcoal filled inside the tubular body is granular charcoal having a particle size of 1 to 3 mm.

According to a test conducted by the present inventor, it has been found that the charcoal has an excellent adsorption effect on granular charcoal having a particle size of about 1 to 3 mm, as compared with fine powder charcoal having a particle size of microns. is doing. The reason for this is not clear, but the fine pulverized charcoal with a particle size of microns has a porosity reduced to several tenths to one-hundredth of that of granular charcoal with a particle size of about 1-3 mm. It is presumed that this is due to the fact that in the case of pulverized charcoal, the fine powder adheres to each other and the surface area decreases.

The charcoal obtained by carbonizing Uwakashi oak at a high temperature of about 1100 ° C. is hard, does not pulverize even after long-term use, and retains the above-mentioned particle size of 1 to 3 mm. It can be suitably used for a water purifier.

Further, the water purifying apparatus of the present invention is characterized in that the charcoal to be filled in the tubular body is packed in a water-permeable bag body to be molded into an inner shape of the tubular body. When charging charcoal into a tubular body, when filling charcoal in a water-permeable bag and molding it into the inner shape of the tubular body to replace charcoal, such as when replacing charcoal Since it is possible to take out and replace the bag together with the bag, the replacement work can be performed quickly. Further, it is possible to prevent the charcoal from flowing out and scattering.
