Description

DETAILED DESCRIPTION OF THE INVENTION OBJECTS OF THE INVENTION The present invention relates to a fine dust eliminator that uses an inclined plate to provide a sedimentation function that adapts to flow rate, flow rate, and permissible particle size.

For example, when carrying out sprinkler irrigation of fields, orchards, etc. or rice field automatic pipeline circulation irrigation, etc., conventionally, it was sufficient to use water that had passed only through a dust remover that removed coarse dust from the polluted water that served as the water source.

However, as the internal structures of sprinkler spray devices and automatic circulation devices for paddy field irrigation gradually become more sophisticated, it is no longer sufficient to remove only coarse dust as before, and even finer particles in the water must be removed more precisely. Without it, functionality would be impaired.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a fine dust remover with an array of inclined plates capable of sedimenting and removing particles larger than the allowable particle size in water.

In the case of the above-mentioned rinsing water, the amount of water used per unit time is relatively small, so the fact that the dust remover is small and sufficient can be used to provide performance with new features.

In addition, because the dust remover is small, the interval between the inclined plates is significantly narrower than that of conventional equipment used for waterworks, etc., and the length of the sedimentation channel is similarly shortened to fully demonstrate its function. can.

Structure and operation of the invention To explain the embodiment of the present invention shown in the drawings, reference numeral 1 denotes a sedimentation tank formed so that the flowing water inside becomes pressurized water, and a raw water inlet 2 which can be tilted arbitrarily in the flow direction. A vertical adjustment mechanism 5 is installed that can be moved up and down by, for example, rotating a screw, with the discharge port 3 side as a fulcrum 4.

In addition, the water level upstream and downstream of the flow path of the sedimentation tank 1 is determined by the pipeline 6a.
, 6b are placed in parallel with glass tubes γa and 7b, so that the water level difference at any given time can be observed.

Further, within the sedimentation tank 1, a plurality of inclined plates 8 are arranged in the same direction and at the same intervals.

The interval between two adjacent inclined plates 8 is extremely narrow compared to commonly used waterworks and industrial waterworks, and is about one-hundredth of that.

Therefore, it is sufficient to make the length of the settling channel extremely short, and 1
About 1/00 is enough.

Further, each inclined plate 8 does not have a zigzag shape, but is inclined in a single direction, leaving a gap 9 on the upper surface of the inclined plate for releasing fine particles, and the ends of each inclined plate 8 are connected to shielding plates 10, 11.
The particles that are surrounded and settled and slide on the upper surface of the inclined plate are discharged into the still water without being hindered by the flow force, and are accumulated in the sedimentation tank 12 without any delay.

The gap 9 formed in the shielding plates 10 and 11 surrounding the end of the inclined plate 8 along the sedimentation tank wall is reduced in width from upstream to downstream. The ends of the water shielding plates 10 and 11 protrude from the ends of the still water area 13.
This allows the emitted particles to be safely released into still water.

Further, as mentioned above, the settling tank 1 has two glass tubes representing the water levels taken by the pipelines 6 a and 5 b from the upper and lower ends of the channel in the tank. a and 7b are arranged side by side to form a water level difference display mechanism 7 that measures the difference in upstream and downstream water levels at a glance to determine the flow rate. Changes in water level can be detected by the vertical mechanism 5 or by a cock (not shown) at the inlet 2. It can be adjusted by

In addition, the vertical mechanism 5 adjusts the slope of the sedimentation channel, reads a scale (not shown) indicating the slope, and sets the slope plate 8 to the required slope with respect to the flow direction. By determining the vertical distance between two adjacent surfaces, it is possible to remove particles larger than the required critical particle size using the settling distance that has already been established.

In addition, the interior of the sedimentation tank 1 is sealed to create pressurized water, and the vertical adjustment mechanism 5 that adjusts the inclination of the sedimentation channel with respect to the flow direction, the cock (not shown) of the inlet 2, and the water level difference between the lower end of the sedimentation channel are displayed. It has the ability to adjust the water level difference display mechanism 7 to remove particles larger than the permissible limit particle size required from time to time and to send the necessary clear water to the outlet 3.

Effects of the invention In the first place, natural water in our country has been almost exclusively used as water for paddy fields since ancient times, but after the war, fields and orchards began to be irrigated, and industrial and urban water use also rapidly increased. I came.

At this point, we had no choice but to cut back on water used for paddy fields.
At the same time, in order to develop modern agricultural water technology and save labor, various improvements have been made to irrigation methods.

In the case of sprinkler irrigation for pipelines in fields and orchards, and automatic circulation irrigation equipment for rice field pipelines, the devices built into the end of the pipeline gradually became more sophisticated. The currently used dust removers alone are of little use.

The main part of these rinsing dust removers, which originally constitute a general dust remover, is to remove floating dust by passing it through a wire mesh.

This method can sufficiently remove floating dust, but it is difficult to remove fine particles suspended in water.

In order to force this to filter, the inner diameter of the mesh must be made much smaller, and when the mesh is made smaller than the fine particles to be removed, it becomes difficult for water to pass through. Removal of particulates is difficult, especially in the case of agricultural water.

Since it is undesirable for agricultural water to mix a chemical solution into raw water to agglomerate and expand suspended fine particles and treat them like dust, the sedimentation method of the present invention is optimal if suspended fine particles are to be treated only by physical methods. It turns out.

That is, the present invention is a removal device that utilizes the sedimentation of suspended fine particles by an inclined plate, in which the separating inclined plate is inclined only in the same direction, and the sliding part of the terminal particles is surrounded by a shielding plate so that the particles remain stationary. Since this device discharges particles into water forming a body of water and completely accumulates them in a sedimentation tank, it is possible to completely and easily remove particles.

In addition, if the pipe wall at the entrance and exit of the flow path in the sedimentation tank is made of a transparent material such as glass so that the difference in transparency between raw water and service water can be determined at a glance, it is possible to observe the turbidity while also The degree of inclination can be adjusted to immediately match the appropriate degree of inclination.
