JPH01315302A - Removing device for solid matter such as dust in channel - Google Patents

Abstract

PURPOSE:To prevent accumulation of solid matters in the inside of a filter element by using a filter piece having only one bored shaft hole to be supported by each shaft of an endless chain belt. CONSTITUTION:An upper sprocket 13 and a lower sprocket 14 are connected to a driving mechanism which rotates an endless chain belt 11 which connects many shafts 12. Only one shaft hole which is to be supported by each shaft 12 of the endless chain belt 11 is bored to a filter piece 1. Since, thus, each filter piece 1 is impressed by its self-weight, stopping effect at reversing position, and pushing effect of an impact plate 16 fitted coaxially to the sprocket in a reversing stage of the filter piece, captured solid matters are removed automatically. Further, since the resistance of water becomes minimum against the channel in the reversing stage of the filter element, that is, the mesh of the filter element becomes maximum, there is no fear for causing accumulation of solid matters in the inside of the filter element.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention continuously removes solid matter such as dust contained in a flow path through which a liquid flows (seawater as cooling water, river water, drainage from a ditch, etc.). Improvements are being made to filter elements for removal or collection.

[Prior Art] As shown in FIG. 6, as an endless filter in a conventional device for removing dust in a flow path, for example,
A filter element as disclosed in the invention of Publication No. 7305 is known, but the basic structure of this filter element is that the filter piece (■) has a center hole (■).
A plate (for example, a rectangular plate ■) with a hole (for example, a rectangular plate ■) is provided, an end ■ is bored at one end of the center hole ■, and f#! It had the shape of a confession drawing board (for example, a fan board (■)) that was slightly shorter than the other board, with an acute protrusion piece (■) protruding from the tip of the outer edge. Then, the holes ■ and ■ of the filter piece ■ overlap each other, and the shafts ■ and ■
-m- was polymerized and at the same time connected in an endless and polygonal manner to constitute a filter element.

[Problems to be Solved by the Invention] The filter piece (2), which is the basic structure of the conventional filter element, not only has a complicated structure, but also has many failures in the entire device, and cannot withstand long-term use. Therefore, manufacturing costs and maintenance costs were high. Furthermore, since the shape of the free diaphragm is complex with a fan-shaped plate and an acute protrusion protruding from its outer tip, dust tends to adhere to it, and a separate cleaning device is required to remove it. Ta. Therefore, not only the manufacturing cost of the entire device is high, but also a large amount of maintenance cost is required.

In particular, the conventional filter piece ■ is provided with a plate (for example, a rectangular plate ■) with a center hole ■, an end portion ■ is bored at one end of the center hole ■, and a free piece slightly shorter than the plate is provided at the other end. It was shaped like a diaphragm (for example, a fan board) with an acute protrusion (■) protruding from its tip. That is, in order to connect the filter pieces (2), the center hole (2) and the end (2) must be supported by bearings, and the shape is complicated.

Therefore, in the conventional dust removal device configured with the filter piece (2), a separate cleaning device is installed to remove the dust that adheres to the filter piece (2) after being captured by the filter piece (2). etc.), the dust removed by the cleaning device enters the inside of the filter element, which is formed into an endless polygonal shape, and the dust accumulated inside forms a large lump, which prevents the smooth operation of the main body of the device. The disadvantage was that it was inhibited. Furthermore, another object of the present invention is to provide a filter element that does not require a cleaning device.

The present invention has been made to solve the above-mentioned problems, and its purpose is to provide a filter element having a single shaft hole that is drilled into the filter piece and having a simple shape.

[Means for Solving the Problems] In order to solve the above problems, the solid matter removal device according to the present invention is first provided with a filter piece that is supported on each shaft of an endless chain belt. The reason is that there is only one shaft hole. Second, a mechanism for pushing out the end of the filter piece is provided on the upper sprocket of the upper and lower sprockets connected to the endless chain belt. Third
In addition, a mechanism for hitting the filter piece is provided on the upper sprocket. Fourthly, the inner arc of the filter piece is centered around the axis of the previous filter piece.
It was formed to form a circular locus with its maximum length as the radius. Fifth, by changing the length or thickness of the filter pieces, the mesh of the filter element made up of a large number of filter pieces can be made variable.

The chain belt 11 is stretched around an upper sprocket 13 and a lower sprocket 14, and is prevented from loosening by a front guide rail 20 and a rear guide rail 21. 24 is the liquid level of the channel.

Note that the frame 15 is installed at a position where at least the upper sprocket 13 is above the liquid level.

The operation of the solid matter removing device according to the present invention will be explained based on the above configuration.

First, it is assumed that the flow path flows from left to right in the figure. In addition, below, focusing on a predetermined filter piece l and the filter piece 1' attached immediately before it, the sections 1-II, ti-m, m-rvtv-v, v-■,
The cases in ■-■, ■-■, ■-■, ■-X, and X-1 will be explained separately.

■-■: When the chain bell (11) with the filter piece 1 attached as shown in the figure is transferred diagonally upward, the filter piece l tends to fall to the left of the shaft 12, but the filter piece 1 Immediately before the lower end 5 of the claw part 4 comes into contact with the upper part 7 of the shaft end of the filter piece 1', which is a shaft support, it does not rotate any further and is captured by the arcuate protrusion 3 of the filter piece l. As shown in Fig. 3, the solid fF2 material is loaded on the front surface of a filter element formed by arranging a large number of filter pieces I vertically and horizontally, and is drawn out from the liquid level 24 and directed diagonally upward. will be transferred to. In this section, the filter element has a mesh of fine and small meshes.

Examples of mesh sizes are shown in FIG. 3, but in addition to gaps in the length direction of the filter piece l and gaps in the lateral direction, there are ribs 10 as shown in FIGS. The size of the mesh can be changed by arbitrarily selecting the number of meshes of the filter element depending on the shape, size, number, spacing, etc. of the meshes.

nm: The filter element is loaded with solids while forming a fine mesh network, leaves the liquid surface and is roughly transferred upwards, so the solids loaded on fff are separated from the liquid and moved to the right. be transferred to.

[-1V: Filter piece l is upper sprocket 1
3, the tip of the cam portion 17 of the impact plate 16 begins to hit the lower shaft end 9 of the filter piece I, pushing the filter piece 1 to the outside of the sub-block 13. Therefore, the lower end 5 of the claw portion 4 of the filter piece 1 begins to separate from the upper shaft end 7' of the filter piece 1'.

IV-V: Roughly rotate the filter piece l to V
When the position is reached, the striking portion of the impact plate 16 applies an impact to the lower shaft end 9 of the filter piece 1, so that the dust adhering to the filter piece 1 is removed. Then, as the filter piece 1 falls to the right, the solid matter captured on the front side of each piece separates and falls into a hopper (not shown) installed below, and the solid matter is discharged out of the device. Ru.

V-Vl: The filter piece 1 rotates together with the impact plate 16 from the position ■ to the position ■, and around the point past the position ■, the striking portion 1 and the lower shaft end 9 separate.

■-■: In the position (■), the filter piece 1 is only supported on the shaft 12 of the chain bell (11).

■-■: When the filter piece 1 enters the liquid level 24 again, the arcuate protrusion 3 and the claw portion 4 are tilted to the right by the flow, and the filter piece and the flow are almost parallel to each other.
The mesh of the filter element is the coarsest. At this time, relatively small solid matter adhering to the surface of the filter piece 1 is also washed away.

■-■: At the position ■, the direction is changed at the position where the tip of the arcuate protrusion 3 of the filter piece 1 starts to contact the lower guide 23, and the lower end 5 of the claw part 4 is placed above the shaft end of the filter piece 1'. 7' begins to touch.

X-1: Tip of filter piece 1 (arc-shaped protrusion 3
) passes through the lower guide 23, a mesh of the filter element is formed, and the mesh of the filter element is formed again on the front guide rail 20 and begins to rise.

Since the above operation is repeated for each filter piece, solids contained in the flow path can be continuously removed.

[Effects of the Invention] The filter element of the present invention has the following numerous effects.

(1) Since the filter pieces are supported on the l-axis, the capturing ability at the bottom part is affected by the weight of each filter piece and interference when inverted, so the phenomenon of pot removal can be prevented.

(2) When the filter pieces are reversed, each filter piece receives an impact due to its own weight, the pushing action of the impact plate coaxially attached to the sprocket, and the action of stopping the reversal position, so captured solids are automatically removed. be done. Therefore, a cleaning device for the filter element is unnecessary.

(3) Since the filter piece is supported by the l-axis, the cross section of the filter element, which is composed of filter pieces as basic units, is
In case (2), the water flow resistance becomes small and narrow with respect to the flow path. In other words, the mesh of the filter element is maximized so that no solids are deposited inside the filter element. Furthermore, as the water flow increases, the surface pressure of the filter element acts automatically, and the resolution of the entire filter element (here, meaning that the constituent components of the filter element are decomposed) becomes maximum.

(4) Shape of the arcuate protrusion, claws, etc. of the filter piece;
By arbitrarily changing the size and angle of inclination of the filter element composed of a large number of filter pieces, it is easy to select the maximum capture capacity of the filter element.

(5) Since the filter piece has a simple shape, it is suitable for low-cost mass production.

(6) Since the tip of the filter piece has a tapered shape with respect to the base, dust adhering to the filter piece can be easily removed.

(7) Since the filter piece is supported on the l-axis, there is no 61 FB on the filter element due to loads other than captured solids, impact, or jamming due to excessively captured substances.

(8) Since the filter piece moves around the shaft, attached dust can be easily removed.
