Description

  The present invention relates to a waste liquid treatment tank that, for example, stores waste liquid and precipitates unnecessary substances during waste liquid treatment in a beer factory, and separates the suspended matter in the upper layer part by overflowing the waste liquid from the upper part. .

For example, Patent Document 1 describes a single-moving cleaning device that automatically cleans a pool or a water tank. Patent Document 2 describes a mechanism for cleaning a pipe with a floating fluid ball in a water intake facility. Patent Document 3 describes a dust removal device in a seawater intake facility.

  In general, a waste liquid treatment tank that performs waste liquid treatment in a beer factory or the like stores waste liquid and precipitates unnecessary substances, and forms an upper edge of the side wall portion in a sawtooth shape (trough) to make it easier for the waste liquid to overflow from the trough. However, when algae or the like adheres to the trough portion, the trough portion is blocked, the overflow is inhibited, and floating sludge is retained in the tank. Further, since the waste liquid treatment tank is often installed outside the rooftop or the like, it is difficult to suppress the generation of algae itself, and conventionally, the algae are removed manually. In particular, in summer, removal work for about 2 hours was required once every two days, which was a heavy burden.

  In addition, the cleaning device of Patent Document 1 can automatically clean the side wall and the bottom surface, but if the side wall is flat, if there are irregularities, troughs, internal piping, etc., the cleaning device can be moved or cleaned. It is doubtful whether it can be demonstrated. Moreover, when only aiming at the removal of the algae from the trough part, the apparatus becomes unnecessarily large.

  Moreover, in patent document 2, since a fluid sphere only flows along a water flow, the effect which removes the algae etc. which adhered to the inner wall is low. Moreover, in patent document 3, there is no effect which removes the stain | pollution | contamination adhering to a wall part only by the removal effect of a floating matter.

  The present invention has been made in view of the above-mentioned problems, and its purpose is to eliminate the need for human work for removing the algae attached to the trough portion of the waste liquid treatment tank, and to increase the driving frequency and the algae generation speed that changes according to the season. It is to realize a waste liquid treatment tank that can set the operation time.

  In order to solve the above-described problems and achieve the object, the waste liquid treatment tank 10 according to the present invention has a bottom part 11 and a side wall part 12 erected in a circumferential shape from a peripheral part of the bottom part. A waste liquid treatment tank for precipitating solids in W, which is formed in a central part of the tank, and is continuously formed on a waste liquid introduction part 13b for introducing the waste liquid into the tank, and an upper edge of the side wall part, A serrated trough portion 14 that traps suspended matter in the upper layer portion, and a waste liquid receiver that is erected on the outside of the side wall portion and into which waste liquid overflows between the side wall portion and the trough portion. A brush unit that has an outer wall portion 15 that forms a portion and a brush portion 16a that abuts against the trough portion of the side wall portion, and moves along the trough portion to remove the suspended matter attached to the trough portion 16.

  Preferably, the brush unit further includes a brush movable unit 17 that reciprocates a predetermined range along the trough portion, and the brush movable unit guides the brush unit along the trough portion. And a brush drive unit 25 to which the brush unit is attached, movable units 21 and 22 that move along the rail unit, and a reciprocating operation by applying a driving force to the movable unit. .

  Preferably, a plurality of the brush units are arranged with respect to the movable part, and the movable part and the brush movable unit are provided in respective regions obtained by dividing the entire circumference of the trough part into a plurality of parts.

  Preferably, the apparatus further includes an operation unit that sets the driving frequency and operating time of the brush unit, and a control unit that controls the brush driving unit based on the set driving frequency and operating time.

  According to the present invention, there is no need for human work to remove algae attached to the trough of the waste liquid treatment tank, and a waste liquid treatment tank that can set the driving operation and the operation time according to the generation speed of algae that changes according to the season is realized. it can.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
