Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a filtration device that can capture and eliminate impurities contained in an undiluted solution using a material and discharge it as a purified solution.

[Conventional technology]

In general, in a filtration device, if the material through which water passes becomes clogged and the overresistance increases, there is a problem with performance, and it is difficult to return the material to the original clean material, and the material must be replaced. When using a purification mechanism using chemicals or diatomaceous earth, the equipment is large-scale, requires injection of chemicals and pipes, and its operation is complicated and requires a specialized engineer, which poses management problems.

In the past, a cartridge system was used, for example, as disclosed in Japanese Utility Model Publication No. 45-30155, in which a mounting tube with a filter was attached to and removed from a mounting plate fixed to the casing so that inspection of the inside of the filter device and replacement of materials could be easily carried out. things are known.

[Problem that the invention attempts to solve]

However, with this conventional type, each of the many mounting tubes with filters must be individually taken out from the casing and inserted into and removed from the round hole in the support plate, making it difficult to attach and remove the filters from the casing and to replace the filters. Moreover, there was a problem in that it required a large space to handle the filter, making it impossible to install it in a narrow place such as a machine room.

This invention aims to eliminate these conventional drawbacks, and allows contaminated materials to be replaced extremely effectively with a simple operation, eliminates the need for flocculants and diatomaceous earth, and significantly reduces maintenance costs. The object of the present invention is to simplify maintenance and management, ensure stable overwork for a long period of time, and provide a highly safe and easy-to-handle overworking device.

[Means for solving problems]

The present invention consists of a plurality of water collection pipes, each consisting of a perforated pipe with a removable layer around the casing, arranged at predetermined intervals in a casing that has an inlet for supplying raw water and an outlet for discharging purified water. Each water collection pipe is opened and communicated with the water collection chamber which is cut off from the raw water inflow side by a partition plate provided, and a support is connected to the partition plate with a connecting rod and movably fitted to the inner wall of the casing. The water collecting pipe is connected and integrated with a plate and is provided in a casing so as to be freely insertable and removable.

〔Example〕

Embodiments of the invention in which the present invention is used as a pool purification device for purifying pool water.
To explain with reference to Fig. 4, first, the open ends of two horizontal cylindrical bodies 1a and 1b, one end of which is open and the other end of which is closed by an end plate, are separated by a blocking plate having a diameter larger than the diameter of the cylindrical body. A casing 1 is formed by removably connecting them with a partition plate 4 therebetween. The longer cylindrical body 1a has a raw water inlet 2 opened in its end plate and accommodates a water collection pipe 5 serving as a water collection pipe inside to form an overchamber 1c, and the cap-shaped shorter cylindrical body 1b
The superfluous water outlet 3 is opened in the end plate, and the pipe end of the water collecting pipe 5 that protrudes through the partition plate 4 is opened inside to form the superfluous water collecting chamber 1d, and the cylindrical body 1a is
It is designed to be attached and detached.

The water collection pipe 5 is a perforated pipe arranged in the axial direction in the casing 1, and is connected to and housed in the partition plate 4 and the support plate 7. For example, in FIG. 1, a disk having a communication port 6 and having a smaller diameter than the inner diameter of the cylindrical body 1a is used as the support plate 7 on the raw water inlet 2 side, and the partition plate 4 without a communication port is used on the superhydrant outlet 3 side. It is used as a support member for both plates, and the end portions of the water collection pipe are fixed to or inserted through the plates to be engaged with each other. In order to increase the overarea, a water collection pipe 5 is installed inside the cylindrical body 1a as shown in FIG.
A plurality of them are arranged on the support plate 7 so as to be arranged and positioned on the circumference.

The water collection pipe 5 has a pipe wall located in the cylindrical body 1a made of a porous member, but the pipe end on the side of the raw water inlet 2 is made of a closed pipe, or is placed against the support plate 7. The support plate 7 can be fixed as a support member closing member (in this case, fixing means such as welding or a support ring is used), or the filter 11 described later can be covered with an open end or a perforated end.

The other end of the cylindrical body 1b that opens into the water collection chamber 1d is made to protrude through the partition plate 4 as shown in the figure to facilitate the connection between the partition plate 4 and the water collection pipe 5. The open end of the water collection pipe 5 can also be fixedly engaged with the water collecting pipe 5 facing forward.

In this way, the water collection pipe 5 is mounted between the support plate 7 and the partition plate 4, and in order to further support the space between them, an auxiliary support plate 7' having a through hole and a communication port 6 for the water collection pipe 5 is provided. They are fixedly arranged at equal intervals as necessary. Further, between the support plate 7 and the partition plate 4, there is provided a support member connecting rod 8 that passes through the auxiliary support plate 7' and connects the two at a predetermined distance, and supports the group of water collection pipes 5. It is constructed in the form of an integrated block. The support plate 7 and the auxiliary support plate 7' are each provided with rollers 9 that roll in contact with the inner peripheral wall of the cylindrical body 1a, and the same cylindrical body 1b of the partition plate 4
A handle 10 is provided on the side, and 5 groups of water collection pipes are arranged in the cylindrical body 1a as an integrated element so as to be freely inserted and removed, facilitating insertion and removal operations.

The water collecting pipe also surrounds a filter 11 forming a superlayer around it. The filter 11 is formed into a hollow cylindrical body that can surround the water collection pipe 5 using an appropriate material such as non-woven fabric or sponge. A single crack 12 extending from the hollow part to the outer periphery is provided in the axial direction so that the water collecting pipe 5 can be connected to and removed from the water collecting pipe 5 from the radial direction with respect to the axis of the water collecting pipe 5, that is, it expands in the axial direction at the separation surface. It has a cylindrical body that can be easily attached and detached.

When installing the filter 11, for example, when three auxiliary support plates 7' are used to divide the space between the support plate 7 and the partition plate 4 (length: 1) into four, a length of 1/4 is preliminarily divided. The filter 11 is used by being attached to each partitioned water collection pipe 5, respectively.

The examples shown in the fifth to seventh figures are examples in which the water collection pipe 5 is densely housed within the casing 1 in order to further increase the overeffective area. It is composed of a plurality of thin rods 8' scattered about. Also, as in this example, in addition to the gap between the inner wall of the cylindrical body 1a and the outer periphery of the support plate 7, the roller 9 mounting portion, and the communication port 6, the support plate 7 and the auxiliary support plate 7'
A notch is provided on the outer periphery of the tank and the gap is enlarged to serve as a communication port 6 to allow smooth inflow of raw water.

The partition plate 4 may be a group of water collection pipes that are fixed to and integrated with the cylinder body 1b, and the partition plate 4 may be positioned in the cylinder body 1a and have a diameter that allows it to slide inside the cylinder body 1a. It is also possible to designate the two chambers divided by 4 as the overchamber 1c and the water collection chamber 1d, respectively, and to detachably attach the end plate as the casing 1 to the cylindrical body 1a. In the latter case, it is preferable to provide sealing by detachably disposing an annular packing around the outer periphery of the partition plate 4.

In the figure, reference numeral 13 denotes a flange provided on the outer periphery of the open end of each of the cylindrical bodies 1a and 1b, and a fastener provided on this flange connects and separates the cylindrical bodies 1a and 1b. 14 is a caster, 15 is an inflow valve, 16 is a hair catcher, 17 is a circulation pump, 18 is an inlet valve, 19 is a flexible tube, 20 is an outflow valve, 21 is a chemical injection tank, 22 is a chemical injection pump, 23 is a filter 11 It is a device to prevent it from coming off.

In addition, as the filter 11, a non-woven fabric wound into a spiral shape, a ring-shaped material fitted one after the other, or an integrally molded material are used, and a filter 11 that is not formed into a hollow cylindrical body is used, but a flat one is used. It is also possible to wrap it at least once around the cross section of the water collection pipe 5 and install it in a spiral shape. Furthermore, the auxiliary support plate 7' is provided with an insertion hole that passes through the water collection pipe 5 equipped with the filter 11, and the partition plate 4 and the auxiliary support plate 7'
It is also convenient to remove the filter from the water collection pipe 5 and attach a long cylindrical filter with no cracks 12 from the axial direction, and the water collection pipe, support plate, auxiliary support plate, partition plate, and connecting rod can be separated. This is also convenient for replacing the water collection pipe itself.

Therefore, the circulating water from the pool is at the raw water inlet 2.
The purified water enters the cylindrical body 1a, passes through the filter 11, flows into the water collection pipe 5, flows out from the cylindrical body 1b, and is again supplied to the pool.

If the filter 11 is clogged and excessive resistance increases and excessive performance decreases, disconnect the cylindrical bodies 1a and 1b of the casing 1, pull the handle 10, and remove the water collection pipe group forming a block from the casing. Take it out from 1. After replacing the filter 11 (or a separately prepared spare collection pipe group), reinsert the water collection pipe group, attach the cylindrical body 1b to the cylindrical body 1a, close the lid, and resume operation as a filter device. I can do it. When taking out and inserting the water collection pipe group, the open end of the casing 1 can be oriented horizontally and diagonally upward while being connected to the pipes by the flexible pipe 19, so that the position where the roller 9 running surface of the casing 1 is extended is It is convenient to bring a trolley to the ground and operate it while running on a continuous slope or horizontal surface, and it is also good to provide guide rails on the running surface of the casing 1 and rollers 9 of the trolley to ensure smooth running. .

[Effect of idea]

In this invention, a plurality of water collection pipes made of perforated pipes with removable overlayers are arranged in parallel at predetermined intervals, and each water collection pipe is connected to a water collection chamber that is separated from the raw water inflow side by a partition plate. The respective openings communicate with each other, and the water collection pipe is connected and integrated with a support plate that is connected to the partition plate by a connecting rod and movably fitted to the inner wall of the casing, and is provided so as to be freely insertable and removable within the casing. As a result, the drawbacks of the conventional system can be eliminated, and the overflow device can be installed as part of the piping, making it compact and large in area, greatly increasing overefficiency, as well as saving space and reducing overfunction due to clogging. When this occurs, the overlayer can be easily replaced, and in other words, many collection pipes with filters can be easily taken out and inserted outside the casing at once, filters can be easily replaced, and backwashing and chemical injection cleaning are possible. This method has great practical effects, such as eliminating the need for any maintenance and management, and since it passes from the entire longitudinal direction of the piping, the amount of collected water that can be obtained as purified water is large, and the purification work can be carried out in a short time.
