Description

Chain Flight Type Sludge Collector With Compound Roller Chain}

      The present invention relates to a sediment sludge collector in a water treatment plant and a sewage treatment plant. The chain is composed of a sprocket wheel having a mixed chain in a sludge collector which transfers sludge settled at the bottom of the sedimentation basin to the hopper by arranging flights at constant intervals. A flight type sludge collector.

      In general, water purification plants and sewage treatment plants are provided with sedimentation basins 1a and 1b each having a rectangular shape of about 70 × 10 × 5 m as shown in FIGS. 1 and 2 to precipitate sludge contained in raw water flowing into the water purification plant and sewage treatment plant. After that, the supernatant water of the sedimentation basin is supplied to the filter paper through the ware flow in the case of the water purification plant, and discharged to the stream after the organic matter purification process in the case of the sewage treatment plant.

      On the other hand, sludge 10 precipitated in the settling basins 1a and 1b in Figs. 1 and 2 are sludge hoppers 5a-5d by a plurality of flights 9 arranged at predetermined intervals on the transfer chain 6. After being collected into the discharge through the manifold pipe (8) installed in the longitudinal direction through a plurality of sludge suction pipe (11a-11d) respectively passed through the lower portion of the sludge hopper (5a-5d), the discharge in the case of water purification plant In the case of a sewage treatment plant, the sewage treatment plant is discharged to a concentration tank. In this case, the sludge 10 collected into the hoppers 5a-5d may be discharged as natural oil by the head difference of the sedimentation basin.

      In more detail, the rotation speed of the drive motor 3 is reduced by the reducer 5, and then power is transmitted to the first sprocket S1, and then the first power transmission chain C1 is used to transfer the power. The second sprocket S2 interlocked with the first sprocket S1 is rotated.

      At this time, third sprockets S3a and S3b are coupled to both ends of the first rotation shaft 13 to which the second sprocket S2 is coupled, respectively, and the fourth sprockets are coupled to one side of the driving rotation shafts 15a and 15b, respectively. The second power transmission chain C2 is wound around the third sprockets S3a and S3b and the fourth sprockets S4a and S4b so as to cooperate with the sprockets S4a and S4b.

      Meanwhile, the transfer chain 6 having a plurality of flights 9 arranged at predetermined intervals includes fifth sprockets S5a and S5b coupled to the first rotation chain driving shafts 15a and 15b and the second transmission chain driving shaft. It is wound around the sixth sprockets (S6a, S6b) coupled to (16a, 16b) and along the settling basins (1a, 1b) as the fifth sprockets (S5a, S5b) and the sixth sprockets (S6a, S6b) rotate. Straight line movement.

      Accordingly, the plurality of flights 9 transfers the sludge accumulated in the settling basins 1a and 1b to the hoppers 5a-5d to transfer the sludges into the hoppers 5a-5d along the slopes 5e and to the hoppers 5a-5d. The sludge conveyed into) is discharged to the outside along the vat pipe (8) through a plurality of suction pipe (11a-11b).

      The conventional sludge collector is processed to 13 mm so that the chain rotational diameter (301R) of the chain chain diameter (301R) of FIG. 3 and the machining radius (207R) of the chain sprocket wheel are exactly matched in the case of the roller chain (210R) and the width of the roller chain (302R) of FIG. ) Is set to 27mm and the tooth width (303R) of the roller chain sprocket wheel is set to 25mm so that it can be combined naturally.

In the case of the casting chain 210F, the cast chain width 302F of FIG. 6 is processed to 19.05 mm so that the rotor diameter 301F of the cast chain 38.1 mm and the machining radius 207F of the chain sprocket wheel are exactly matched. ) Is 35mm and the width of the cast chain sprocket wheel (303F) is 33mm, it is prescribed to be combined naturally.

Accordingly, even though the pitch of the roller chain pitch 304R and the cast chain pitch 304F are 152.4 mm, the industrial specifications of each country are specified so that the roller chain cannot be used in combination with a cast chain sprocket wheel.

Therefore, to solve the above problems, it provides a chain flight type sludge collector having a mixed chain that freely selects the cast chain and roller chain freely in common with the diameter of the rotating body of the chain.

In the sludge collector which transfers and discharges the sludge settled at the bottom of the sedimentation basin to the hopper with the plies arranged at regular intervals from the sedimentation basin of the water treatment plant and sewage treatment plant, the cast chain and the roller chain can be freely replaced. A chain flighted sludge collector having a mixed chain is provided.

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

      7 is a coupling diagram of the chain sprocket wheel having the mixed chain of the present invention, and FIG. 8 is a cross-sectional view of the sprocket wheel having the mixed chain of the present invention.

      First, in the sludge collector according to the present invention, as shown in FIGS. 7 and 8, the processing radius 207C of the mixed roller chain sprocket wheel is the diameter of the rotating body of the cast chain 301F and the diameter of the rotating body of the roller chain ( 301R is 19.05mm, which is half of the rotating body radius (301F) of the large diameter cast chain, and the tooth width 205c of the mixed roller chain sprocket wheel is the tooth width 303R of the roller chain sprocket wheel and the chain sprocket wheel of the cast chain. The mixed chain sprocket wheel is assembled to the shaft 201 by 25 mm, which is the tooth width 303R of the roller chain sprocket wheel, among the tooth width 303R of the roller chain sprocket wheel, among the tooth widths 303F.

At this time, if the roller radius (301R) of the roller chain is set to 38.1mm as the rotating body radius (301F) of the cast chain, and the chain is replaced by the roller chain when the chain is replaced due to the continuous use of the sludge collector. It is provided to the sludge collector which has a mixed roller chain used as a substitute.

In the above embodiment, the use of a chain flight type sludge collector having a mixed roller chain in the sludge collector when one representative chain is used has been described, but it can be easily changed by those skilled in the art regardless of the type of chain. Do.

      In the present invention, the conventional chain flight type sludge collector has been specified by the industrial standards of various countries around the world to use a chain suitable for the shape of the chain sprocket wheel, it was impossible to replace the chain and chain sprocket.

In the sludge collector constructed for the conventional cast iron chain sprocket wheel, when the chain is replaced with a roller chain, the type of chain can be used by using a mixed roller chain whose chain rotor diameter is 38.1 mm, the rotor diameter of the cast chain. It is possible to provide a sludge collector which is not limited to this.

Although the present invention has been shown and described with reference to certain preferred embodiments, the present invention is not limited to the above-described embodiment, and those of ordinary skill in the art to which the present invention pertains without departing from the spirit of the present invention. Changes and corrections will be made. Such modifications are intended to fall within the scope of the claims.
