Description

  The present invention relates to a dust remover used in a river drainage station or the like, and in particular, by preventing spillage of dust at both end portions of the rake, it prevents the entry of dust into the rake guide groove, and causes foreign matter to be caught. The present invention relates to a dust remover that can prevent an overload stop of the dust remover.

In river drainage stations, for example, chain type dust removers are often used.
This chain type dust remover has a bar screen installed so as to block the water flow in the water channel in order to remove solids contained in the water in advance, and along the screen, the residue trapped on this screen is lifted and discharged. The rake which moves is provided.
The rake is installed on a pair of endless chains arranged side by side, and the comb-shaped rake teeth mesh with the bar screen to move the screen so that the dust on the eyes of the screen is lifted.

  By the way, the rake has a flat base portion for connecting the rake teeth, and the dust scraped off by the rake teeth is placed on the base portion and conveyed upward. There was a problem that the dust spilled from the end, entered into the groove portion of the rake guide that guides the rake, the foreign matter got caught, the dust remover stopped overload, and the dust removal operation was hindered.

  In view of the above-described problems of the conventional dust remover, the present invention prevents dust from falling into both sides of the rake, thereby preventing dust from entering the rake guide groove, and removing the dust by biting foreign matter. An object of the present invention is to provide a dust remover that can prevent an overload stop of a battery.

In order to achieve the above object, a dust remover according to the present invention has comb-shaped rake teeth disposed on a flat plate-like base of a rake body passed between a pair of endless chains arranged side by side. In the dust remover that moves the rake along the screen and lifts up the dust on the screen, side plates that are substantially perpendicular to the longitudinal direction of the rake are erected on both side ends of the flat base of the rake body. characterized in that it was.

According to the dust remover of the present invention , the side plate can prevent spillage of dust at both end portions of the rake, and can prevent entry of dust into the rake guide groove portion. An overload stop can be prevented.
Moreover, the attachment of the side plate is simple and inexpensive, and a great effect can be obtained with a small number of steps and a small cost.

  Hereinafter, embodiments of the dust remover of the present invention will be described with reference to the drawings.

1 to 3 show an embodiment of the dust remover of the present invention.
In this dust remover, the screen 1 is installed so as to block the water flow in the water channel, and the comb-shaped rake 2 is moved along the screen 1 so that the dust G on the screen 1 is lifted up.
In the dust remover, side plates 3 are provided at both end portions of the rake 2 so as to be substantially orthogonal to the longitudinal direction of the rake 2.

  The screen 1 captures the dust that flows down, and although not shown in the figure, the screen bars 11 are arranged in parallel at equal intervals and fixed at a constant mesh width with long bolts, nuts, and spacers. 11 captures garbage in the running water and allows the running water to pass between the screen bars 11.

The rake 2 is installed on a pair of endless chains 4 arranged side by side, and the comb-like rake teeth 21 mesh with the screen 1 and move to scrape the dust G of the eyes of the screen 1. It is supposed to be fried.
The chain 4 travels along a guide rail 5 installed in an annular shape, and the rake 2 is screwed in a state of being divided into a plurality of rake bodies 22 passed between the pair of chains 4. Has been.

The side plates 3 at both end portions of the rake 2 are made of metal plates arranged so as to be orthogonal to the longitudinal direction of the rake 2, avoiding the rake teeth 21 so as not to interfere with the screen bar 11, and connecting the rake teeth 21. It is erected on a flat base 23.
The side plate 3 can be easily replaced only by attaching it to the rake 2 at both end positions or by attaching it to the rake body 22 with bolts.

Thus, the dust remover of the present embodiment is a dust remover in which the comb-shaped rake 2 is moved along the screen 1 and the dust G of the screen 1 is lifted up. Since the side plate 3 that is substantially orthogonal to the longitudinal direction of the rake 2 is provided, the side plate 3 can prevent the spillage of dust G at both ends of the rake 2 and prevent the entry of the dust G into the rake guide groove. Thereby, the overload stop of the dust remover due to the biting of foreign matter can be prevented.
Further, the side plate 3 is easily and inexpensively attached, and a great effect can be obtained with a small number of man-hours and a small cost.

  As mentioned above, although the dust remover of the present invention has been described based on the embodiments thereof, the present invention is not limited to the configurations described in the above embodiments, and the gist of the present invention, such as appropriately combining the configurations described in the embodiments. The configuration can be changed as appropriate without departing from the scope of the invention.

  The dust remover of the present invention is characterized by preventing dust from falling into the rake guide groove by preventing dust from falling off at both ends of the rake and preventing overload stop of the dust remover due to foreign matter biting. Therefore, it can be suitably used for, for example, a chain type dust remover.

An embodiment of the dust remover of the present invention is shown, (a) is a side view showing the rake of the upper part of the apparatus, (b) is a side view showing the rake of the arrangement portion in the water channel. It is a fragmentary top view which shows the rake of the dust remover. The rake is shown, (a) is a side view and (b) is a partial front view.

Claims (1)

The rake formed by arranging comb-like rake teeth on the flat base of the rake body passed between a pair of endless chains arranged side by side is moved along the screen so that the trash on the screen In the dust remover, the side plates substantially perpendicular to the longitudinal direction of the rake are erected on both side ends of the flat base portion of the rake body .
