Description

[Detailed Description of the Invention] A. Field of Industrial Application The present invention generally relates to a liquid filtration device for precision filtration of liquid, and specifically, a wire mesh element for coarse filtration is inserted near the outer periphery of a filtration chamber in the body. The present invention also relates to a liquid filtration device in which a large number of cartridge filter cylinders for precision filtration are arranged within the wire mesh element.

B. Prior Art As one of the means for precisely filtering liquid, there is a cartridge filter machine in which a cartridge is installed upright within the body of the filter machine in a replaceable state.

This cartridge filtration machine has a partition plate on which a cartridge filtration tube is erected inside the body, which is divided into a filtration chamber and a liquid chamber.A liquid inlet pipe is connected to the filtration chamber, and a liquid outlet is connected to the liquid chamber. connect the pipes,
The polluted liquid was sent to the filtration chamber through the liquid inlet pipe and filtered through each cartridge filter cylinder, and the filtrate was sent to the liquid chamber and then sent to the next process through the liquid outlet pipe.

C. Problems to be Solved by the Invention In such a cartridge filter, clogging easily occurs, and it is troublesome to replace the cartridge filter every time, resulting in large time and economic losses. In order to eliminate this time and economic loss, a method has been adopted in which the polluted liquid is coarsely filtered using a separate wire mesh filter, and then filtered using a cartridge filter. This increases the cost of equipment and piping, and requires a large space for equipment and piping.

D. Means for solving the problem In view of the above points, in this invention, the partition wall plate 2
A body 1 is provided which is divided into a filtration chamber 1a and a liquid chamber 1b, and a liquid inlet pipe 3 is communicated with the filtration chamber 1a, and a liquid outlet pipe 4 is communicated with the liquid chamber 1b.
A receiving frame 9 is provided with a sufficient gap formed between the inside and the inner wall of the body, a wire mesh element 6 for coarse filtration is inserted and fixed in the receiving frame 9, and a cartridge filtration for fine filtration is inserted into the wire mesh element 6. Tube 10 cap 1
A coil spring 24 is interposed between the top surface of each cartridge filtration cylinder 10 and the lid body 5, and the upper opening surface of the body 1 is connected to the lid body 5.
A liquid filtration device with a liquid-tight cap.

E. Effect The polluted liquid to be filtered is supplied to the filtration chamber 1a of the body 1 from the liquid sending pipe connected to the liquid filling pipe 3 through the liquid filling pipe 3.

The polluted liquid supplied to the filtration chamber 1a flows along the inner wall of the body 1, and is then coarsely filtered through the wire mesh element 6.

The liquid coarsely filtered by the wire mesh element 6 is finely filtered by a cartridge filter cylinder 10 within the wire mesh element 6, sent as a filtrate from the mouthpiece 11 to the liquid chamber 1b, and then passed from the liquid chamber 1b through the liquid outlet pipe 4 to the next source. The liquid is sent to the process.

F. Example Hereinafter, one example of implementing the present invention will be described in detail based on the drawings.

1 is a partition plate 2 fixed to the inner lower part of the filtration chamber 1a.
It is a cylindrical body with a bottom divided into a liquid chamber 1b, and a liquid inlet pipe 3 is connected in communication with the side surface line direction leading to the filtration chamber 1a, and a liquid outlet pipe 4 is connected in communication with the center of the bottom part leading to the liquid chamber 1b. Five lids are attached to the upper opening.

6 is a wire mesh element for coarse filtration in which a wire mesh 8 is superposed on a cylindrical punching plate 7; a filter chamber 1a;
It is inserted into the filtration chamber 1a along a receiving frame 9 fixed to the inner wall of the filtration chamber 1a.

Reference numeral 10 designates a cartridge filter cylinder for precision filtration, in which a cap 11 at the lower end is fitted into a hole 2a of a partition plate 2 in a wire mesh element 6, and the precision-filtered filtrate is passed through a liquid chamber 1b.
The upper surface is pressed downward by a coil spring 24.

A triangular core 10a is inserted into the cartridge filter cylinder 10.

The body 1 is supported on the floor by four legs 13.

A drain socket 14 is screwed into the side surface of the drain pipe 4 for communication.

The lid body 5 is made liquid-tight to the body 1 by fitting a hinge bolt 15, which is swingably supported on the outer circumference of the upper end of the body 1, into a notch 16 cut in the outer circumference of the lid body 5, and tightening a nut 17. crown together.

Further, an air bleed socket 18 is screwed into the lid body 5 for communication, and a lifting bolt 19 is connected to the lid body 5 at the center.
It has a structure in which it is suspended from a suspension rod 20 via.

A lifting bolt 19 that is swingably supported by a mounting piece 21 in the center of the lid body 5 passes through a hanging rod 20 at its upper end, and a handle 22 is screwed into its upper end. The structure is such that the body 5 is lifted up.

A hanging rod 20 that suspends and supports the lid 5 is rotatably supported by a bracket 23 attached to the side surface of the body 1, so that the lid 5 can be moved from the upper surface of the body 1.

The liquid to be filtered enters the filtration chamber 1a of the body 1 from the liquid inlet pipe 3, is first coarsely filtered by the wire mesh element 6, and then finely filtered by the cartridge filter cylinder 10, and the filtered liquid is communicated with the liquid chamber 1b. The liquid is sent to the next process from the liquid discharge pipe 4.

G. Effect of the invention As described above, in the liquid filtration device according to the invention, the wire mesh element 6 is inserted into one body 1 with a sufficient space formed by the receiving frame 9, and the wire mesh element 6 is A large number of cartridge filtration cylinders 10 are installed upright in the body 1, and after coarse filtration is performed in the body 1, fine filtration is performed in the cartridge filtration cylinders 10. Therefore, clogging of the cartridge filter cylinder 10 is suppressed, and it can be used for a long time and is economical. Also,
Compared to a method that uses a wire mesh filter in combination, it has practical and economical effects such as lower equipment costs and no need for a large installation space.

Note that the wire mesh emerent 6 allows the filter surface to be regenerated.
