Description

[Detailed description of the invention] This invention relates to a pulling-up type dust remover that uses a water wheel as power.

Conventionally, the screen of a water turbine-powered dust remover was fixedly placed in the flow path.

Therefore, it was difficult to remove the dust adhering to the screen, and if the direction of the water flow in the flow path was changed, the dust would adhere to the back of the screen, causing water channel loss, and the dust removal efficiency was extremely low. It was low.

This invention provides a pulling-up type dust remover that can eliminate such drawbacks, and is equipped with a rake device that circulates by a water wheel on a screen installed in a waterway, and the upper end of the screen is pivotably mounted. At the same time, by connecting the lower end of the screen to a hoisting machine installed on the upstream waterway side wall via a rope, the screen can be pulled up by the operation of the hoisting machine, and at the same time, a rake claw is installed in front of the lower end of the screen. A plurality of screens are arranged in parallel at intervals to ensure the collection of dust at the bottom of the waterway, and furthermore, below the bottom of the screen,
This device is characterized in that it is equipped with an auxiliary screen that escapes and automatically returns by engagement with the circulating rake, thereby completely removing dust from the lower end of the screen.

Furthermore, the structure and operation of this invention will be explained in detail with reference to the drawings.

A screen 2 is installed at an angle across the entire width of the waterway 1 so that its upper end is located slightly downstream, and a support 4 is provided above the side wall 3 of the waterway 1. 5
A pair of left and right drive sprockets 6 are attached to this main shaft 5.
A pair of left and right driven sprockets 8 are pivotally supported on the screen frame 7 below the fixed waist side wall 3, and a rake device 11 having an appropriate number of rakes 9 attached to a chain belt 10 is suspended from both sprockets 6.8.

A water turbine 12 is mounted rotatably on the downstream side of the screen 2, and the rotation shaft 13 of this water turbine 12 and the main drive shaft 5 of the rake device 11 are connected by an appropriate coupling mechanism 14. and the drive shaft (
(not shown) are also connected via the connection mechanism 14.

A guide sprocket 16 for the chain belt 10 is provided below the rake device 11.

Therefore, the flow of seawater or river water from upstream to downstream applies pressure to the packet-shaped vanes 17 and rotates the water wheel 12.
The rotational force is transmitted to the rake device 11 and the garbage conveyor 15 via the coupling mechanism 14.

Therefore, the rake 9 rises along the screen 2 while raking up the dust adhering to the screen par, and by turning over to the back side of the screen 2, the rake 9 discharges the dust onto the conveyor 15 and descends into the water, where it is circulated. be.

Now, in this invention, as shown in FIGS. 1 and 2, the upper ends of the left and right screen frames 7 are rotatably pivoted 18 to the support base 4 or the side wall 3, and the side wall 3 on the upstream side of the screen 2 A manual or electric hoisting machine 19 is provided above, and left and right hoisting drums 21 are fixedly mounted on a hoisting shaft 20 of this hoisting machine 19.
Since the end of the screen 2 is connected to the lower end of the screen frame 7, the rope 22 is hoisted up by the operation of the hoisting machine 19, and the screen 2 rotates around the pivot portion 18 and rises, almost above the waterway. It will be raised to .

By pulling up the screen 2 in this way, not only can waterway loss be eliminated and damage to the screen 2 when the waterway is idle, but also the screen frame 7 in front of the lower end of the screen 2 has a substantially triangular side surface and a sharp point 23. Since a plurality of rake claws 24 are arranged in parallel, dust can be completely removed from the bottom of the waterway where dust passes through the lower end of the screen 2 and reduces the dust removal efficiency.

In other words, the dust at the bottom of the water channel 1 is pulled up together with the screen 2 while being caught by the rake claw 24 having the sharp point 23, and is removed cleanly in the pulled up state.

Furthermore, in order to completely remove dust from the bottom edge of the screen, a second
As shown in FIG. 3, a support shaft 25 is rotatably mounted on the screen frame 7 in front of the lower end of the screen par 2a, and a plurality of auxiliary screens 26 are erected on the support shaft 25. The bullet 27 is attached to the support shaft 25 so that it escapes while accumulating restoring force when engaged with the rake 9.
A suitable stop (not shown) is provided to hold the auxiliary screen 26 in place.

Therefore, the dust attempting to flow downstream from the space below the screen par 2a is caught by the auxiliary screen 26 and is prevented from flowing downstream.

When the rake 9 circulates and reaches the lower end of the screen par 2a, the rake 9 and the auxiliary screen 26 engage with each other, and the auxiliary screen 26 inclines while accumulating the restoring force of the bullet 27.

When the rake 9 passes through, the restoring force of the bullet 27 automatically returns it to the normal position and locks it with the stopper.

In this case, when the auxiliary screen 26 escapes, the rake 9 is raking up the dust, so there is no fear that the dust will flow downstream.

Further, the dust caught on the auxiliary screen 26 is removed by pulling up the screen 2.

In addition, in order to prevent dust from flowing from the space between the screen frame 7 and the side wall 3, a pipe 30 provided at one end of the dust removal plate 29 is rotatably connected to a C-shaped support pipe 28 installed vertically on the side wall 3. Since the other end of the dust removal plate 29 is set in contact with the screen frame 7, the dust removal plate 29 rotates around the pipe 30 as the screen 2 is pulled up, making it possible to completely remove dust. , its dust removal efficiency is significantly improved.

Note that Patent No. 9056 and Japanese Patent Publication No. 48-3998 have been proposed, but since neither of these uses a water wheel as the motive force, the loss of driving power is large, and
Since the screen pulling device is disposed on the upper end pivoting portion side of the screen, the pulling blade becomes large and a large-sized lifting device is required.

In addition, since dust removal plates are not provided on both sides of the screen, there is a drawback that dust easily passes through from both sides of the screen.

However, in the present invention, the water turbine is used as the drive source for the rake device, which reduces the driving power, and the pulling device is installed on the waterway side wall at the bottom of the screen, so the bottom end of the screen can be pulled directly upward. It can be lifted up using a small lifting device, but there are rotatable dust removal plates on both sides of the screen, which prevents dust from passing through from both sides of the screen and provides a good dust removal function. It will be done.
