Description

Filtration device and its operation method {The apparatus and operate method of filter}

The present invention relates to an automatic filtration device and a method of operating the same, wherein the filter is washed with water to remove impurities when the amount of impurities is accumulated in the filtration layer for filtering water, and then the water is filtered again. The present invention relates to a filtration device and a method of operating the filter medium for completely removing foreign matter accumulated in the filter medium by thoroughly washing the filter medium during backwashing.

In the prior art, an 'automatic upflow filter' which not only filters up the raw water supplied from the head tank by using a diaphragm valve installed in the diaphragm but also washes the water by upward flow during backwashing of the filtration layer is disclosed in Korea Patent Publication. Described in number 87-3400,

A backwash water drain pipe and an air supply pipe are respectively installed in the filtration chamber under the diaphragm provided with the non-return valve and the pressurization chamber at the bottom of the filtration chamber, and a backwash water purification pipe is connected between the bottom of the water purification chamber and the pressurization chamber. An automatic upflow filtration device to stabilize the bed is disclosed,

Since the conventional techniques have a large amount of suspended solids trapped in the filter medium, there is a drawback that the effective removal of the suspended solids trapped in the filter layer is not performed by the water-only backwashing method using only backwash water. There have been a lot of difficulties and problems such as the generation of heated filtered water due to the temperature rise of the water in the summer.

In order to solve the above problems, the present invention completely removes foreign substances adhered to the filter medium by using a backwashing device specially manufactured in the apparatus of the present invention, and forms a cooler and a water heater on the outside of the apparatus to filter the temperature of the filtered water. It is an object of the present invention to provide a filtering device capable of filtering by an automatic control of a central computer and a method of operating the same according to consumer's preference.

In order to achieve the object as described above, the present invention is to recover the used water and to filter by using a special backwashing device installed in the filter and then to control the temperature from the temperature controller to the cooler and heater to send the filtered water to the storage tank for reuse The present invention relates to a filtration device and a method of operating the same.

Conventionally, the backwashing water was discharged to the sewer until the end of the backwashing, which consumed a lot of water. However, when the apparatus of the present invention is used, the backwashing water generated is continuously rotated until the backwashing is completed. It is an economical device that saves water discharged.

The present invention is a device that makes it possible to use a filtration device that can be used continuously for a long time as a general filtration, the water purifier should be replaced with a filter after water purification, the filtration device of the present invention is repeated by regenerating the filter material by back washing It can be used semi-permanently. Since the filter medium contains a large amount of silicon components, microorganisms and other filtration materials do not penetrate into the filter medium. It is a filtration device that can be operated simply and manually.

The backwashing device is specially manufactured to effectively remove foreign substances attached to the filter medium during backwashing, and is a backwashing device using the principle of completely mixing the filter medium by using the backwashing water and compressed air.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

In detail, as shown in FIG. 1, an air blower and a temperature controller 11 are installed outside the filtration device 20, and the temperature controller is heated and cooled by the cooler 12 and the heater 13. The adjustment can be made manually, but also by the central computer (15) to automatically adjust,

In the backwashing device installed inside the filtering device, as shown in FIG. 2, a filtering net is installed at an upper portion of the upper head 21 of the central pipe, and three filtering nets are formed along the cylindrical surface in the peripheral cylindrical wall. Is surrounded by a cylindrical cylinder 26, the lower portion of the cylindrical cylinder is formed with an outer cylinder 27, the outer wall of the outer cylinder is provided with six cube outlets 24, parallel to the The strip pipe 22 is formed at a 45 degree angle to surround the cube outlet 24, and the strip pipe 22 is configured with four outlets 23.

It can be seen that the lower portion of the filter is composed of a drain pipe network 28, and the upper portion is composed of a preliminary discharge pipe, a supply pipe, a three-way valve 30, 30 ', a sewage pipe, a filtrate pipe, and the like.

Referring to the operation state, the filtration process is the wastewater is introduced from the lower portion of the filtration device, that is, A of Figure 3, the wastewater is introduced into the three-way valve 30, and passes through the filtering network of the central pipe upper head 21 of the outer cylinder 27 It rises along the cylinder column 26 via the lower part of the outlet network 25 formed in the lower part of the cube outlet port 24 attached to the outer wall, and becomes the filtered water through the outlet port in the center to be discharged to B and used as a filtration device. When the degree of efficiency drops, the three-way valve 30 is closed by the central computer 15 automatically and backwashing is started.

In the reverse washing process, water is introduced from the outlet B in the reverse order of the filtration process, and the compressed air generated in the air blower 10 descends along the cylinder column 26 together with the water. In order to mix water and air with the strip pipe 22 formed on the outside of the outer cylinder 27 and the outlet 23 connected to the strip pipe, the filter medium is mixed with the strip pipe 22 attached to the outer cylinder 27. The washed water passes through the meshes of the upper head 21 of the central pipe and passes through the three-way valve 30 'while the water and the air come out through the outlet network 25 formed at the lower side, and the filter medium is mixed. After going back to the filtration device 20 and continuing to backwash, after a certain time as directed by the central computer 15, the backwash contaminated by washing is discharged through the upper pipe to complete the backwashing. Normal again It relates to a repeating apparatus for filtration carried out.

Filtrate filtered as described above may be used to adjust the temperature of about 20 ℃ using the heater 13 and the cooler 12 in the temperature controller (11).

The present invention can be used in a variety of applications such as soybean sprout water recycling and soybean sprout water recycling, soybean cultivation water recycling, hydroponic cultivation water recycling, water film cultivation water recycling, fish farm filtration water purification and general drinking water and household water purification.

According to the present invention operating as described above, by continuously rotating the backwash water until the backwash is completed, the water discharged during backwashing can be drastically reduced, and the backwashing can be efficiently attached to the filter medium. There is an effect by the automatic control of the central computer to completely remove the foreign matter, and to form a cooler and a water heater on the outside of the device to filter the temperature of the filtered water according to the consumer's preference.
