Description

[Detailed explanation of the idea] This invention relates to a rotating cylindrical filter.

Conventionally, this rotating cylindrical filter is equipped with a rotary valve at one end of the hollow shaft supporting the furnace body, and by switching the rotary valve, clarified liquid is pumped through the hollow shaft every revolution of the hollow shaft. Inhalation, suction of cleaning liquid, and blowing off of removed substances are performed continuously.

However, this requires a drive source and transmission mechanism to rotate the cylindrical furnace body together with the hollow shaft, and a rotary valve must be installed at the end of the shaft.
There are problems in that the overall structure of the device is complicated, maintenance is troublesome, and it is expensive in terms of manufacturing costs and running costs.

The present invention was proposed in view of these points, and is designed to rotate the furnace body using the liquid to be treated flowing into the filter.

Hereinafter, embodiments of the present invention will be described based on the drawings.

Fig. 1 shows a partially cutaway perspective view, Fig. 2 shows a longitudinal sectional view,
In the figure, the filter S is formed by covering the opening 2 of a cylindrical filter main body 1 with one end open, which is placed horizontally, with a blind lid 3 to form a hermetic shape. It is constructed by accommodating a furnace body 5 having a shape.

A liquid inlet passage 6 to be treated is connected to the upper half circumferential surface of the filter main body 1 toward the negative side in the circumferential direction, and an overflow passage 7 and a removed material extraction passage 8 are connected from the other side in the circumferential direction.

The furnace body 5 housed in the filter chamber 4 is connected to one side wall 9 of the filter body 1.
A treated liquid extraction pipe 10 that penetrates and enters the filtration chamber 4
It is rotatably supported via a bearing 11 on the filter main body 1 in a cantilevered manner.

In this furnace body 5, a mesh 13 is stretched around the circumferential surface of a frame member 12, and blade plates 14 are made to protrude from the outer peripheral surface of the mesh 13 at appropriate intervals in the circumferential direction. It is arranged in a slightly inclined state with respect to the flow direction of the inflowing liquid to be treated.

Thereby, the inflow pressure of the inflowing liquid is applied to the vanes 14 to rotate the furnace body 5.

An air pipe 15 for cleaning the furnace body is inserted into the inside of the treated liquid take-out pipe 10, and the tip of this air pipe 15 passes through the plunge end of the treated liquid take-out pipe 10 and is connected to the secondary filter S. It protrudes into a chamber 16, and a blowout waist nozzle 17 is connected to the circumferential surface of the protrusion.

This nozzle 17 is located in the upper half of the secondary chamber 16 and faces a removed material outlet 18 formed in the filter body 1, and is formed as a wide-mouthed nozzle that extends over almost the entire length of the furnace body 5.

These furnace bodies 5 can be assembled and disassembled from one direction by removing the blind plate 3 that closes the opening 2 of the filter body 1.

Reference numeral 19 in the figure is a drain passage led out from the lower part of the filter main body 1, and this drain passage 19 is shut off by a shutoff valve (not shown) during use.

FIG. 4 shows another embodiment of the present invention, in which the furnace body 5 is pivotally supported on the filter body 1 in a manner such that it is supported on both sides, and the treated liquid extraction pipe 10 is inserted through this pivotal portion. and a cleaning air pipe 15.

As described above, in the present invention, a cylindrical body with vanes protruding from the outer circumferential surface is rotatably supported on a treated liquid take-out pipe fixed to the filter body, and the inflowing liquid to be treated is Since the furnace body is rotated by pressure, a dedicated drive source or transmission mechanism for rotating the furnace body can be omitted.

In addition, since the entire filter can be disassembled from one side, maintenance can be easily performed by removing the furnace body, simplifying the structure of the filter and reducing manufacturing and running costs. can be significantly reduced.
