The present invention is for the sedimentation lifting device used to lift the sedimentation sedimentation is installed in the sedimentation sites, such as sewage treatment plant, and more specifically, the structure of the entire lifting device is greatly simplified by installing so as to vertically lift It is about the salvage phase of the settlement.

Conventional acupuncture lifting machine, L-type type (utility model notification No. 89-2197) and the movable chain gears installed in the upper portion is installed to be axially installed to rotate the lower portion of the lifting portion to be raised horizontally using a wire rope There was a T-type type (Utility Model Registration Application No. 93-15314, which was designed by the applicant of the present applicant), which caused the chain to be pulled up so that the lifting part was lifted because it moved outward, respectively.

However, in the case of the former L-type lifting device, the structure for rotating the lower part of the lifting part is complicated and expensive, so there is an uneconomical disadvantage.

In particular, when the chain is changed in length of the chain spanning the inner and outer positions of the rotation point, the chain takes a lot of load and the rotation operation is not smooth, and in some cases, the chain is broken. there was.

In addition, the lower part of the lifting portion is inclined state because there are many problems, such as when the sediment is piled up on the floor is not easy to remove in time.

On the other hand, in the case of the latter T-type lifting machine, the chains of movable chains installed at both sides of the upper part of the chain are moved forward and backward to increase the chain spacing so that the chain is lifted vertically to raise the lower part of the lifting part. The longer the length, the more the number of chain gears and buckets, and the overall structure is large and complicated to produce a lot of production costs, there was a problem of uneconomical lighting.

The present invention has been devised in view of the problems of the conventional immersion lifter, and its object is to provide a simple and economical tack lifter.

This object of the present invention is achieved by providing an acupuncture lifter configured to elevate the entire lifting part vertically in view of the fact that the height of the gas is not limited because the settlement is an open air. It is provided with the lifting part and the lifting means which are installed up and down perpendicularly to a base body.

The lifting portion is composed of chain gears which are installed on both sides of the base and the upper and lower ends thereof, a chain which is hung between these upper and lower chain gears, and a plurality of buckets and drive motors installed at appropriate intervals between the chains.

The settling spread by the bucket is dropped on the conveying conveyor by the hopper attached to the gas and is taken out of the settling basin.

The lifting means binds one end to the stop pulley via the cylinder and the lifting pulley lifted by the cylinder rod, and the other end is composed of wire ropes bound to a predetermined position of the lifting part base via guide pulleys condensed on the body.

Therefore, when the cylinder is driven to raise the lifting pulley, the other end of the wire rope bound to the lifting part is pulled, so the lifting part is vertically raised. On the contrary, when the lifting pulley is lowered, the lifting rope is not pulled. It is lowered vertically by its own weight.

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

In the figure, reference numeral 10 denotes a sedimentation basin, and a bogie 11 is installed on the upper part of the settlement.

The trolley 20 of the lifting machine is fixedly installed on the trolley, and the lifting unit 30 is installed to vertically penetrate the center of the trolley 11 with the base.

The base 20 is provided with lifting means for raising and lowering the lifting part 30.

In addition, the cart 11 is provided with a carry-out conveyor 12 for transporting the lifted saliva to the outside of the settlement 10, and the gas 20 is carried out by the lifting section 30, the spilled conveyor ( 12) The hopper 21 which guides so that it may fall up is provided.

The lifting portions 30 are chain gears 33, 33 ', 34 and 34' which are respectively condensed on both end sides of the main shafts 32 and 32 'mounted on the upper and lower end sides of the base 31. ) And chains 35 and 35 'hooked between these upper and lower chain gears, and a plurality of buckets 36 and two lifting motors 37 mounted on both sides at appropriate intervals between the chains. It is composed of

At both ends of the lower spindles 32 and 32 ', the feed screws 38 and 38' are fixed to transfer the acupuncture to be lifted to the bucket 36 side, and at the rear side, the guide cover 39 is installed and settled. It is possible to smoothly transfer to the bucket 36 by the transfer screws 38, 38 '.

In addition, the guide hopper 30 'formed at the upper and lower sides of the lifting portion 30 is stretched and installed in the state in which the lower end is fixed to the base 31 on the upper end and the hopper 21, respectively.

Therefore, the length of the guide hopper 30 'is increased as the lifting part 30 is raised, so that the swelling that is pumped up and poured out of the bucket 36 is not bound to the lifting position of the lifting part 30. Let it fall into (21).

On the other hand, the upper part of the body 20 is installed by constricting the striking rod 23, which is hung the tension spring 22 at one end, and hitting the bucket 36, which is pouring out the sand sprinkled by the other end with a suitable force In addition, it is necessary to perform the function of brushing the bucket so that no residues stick to the bucket.

The elevating means includes a cylinder 40, an elevating shaft 42 mounted transversely to the upper end of the rod 41 of the cylinder, and a stop placed at its lower position so as to be isolated from the elevating shaft at an appropriate interval. A plurality of lifting pulleys 44, 44 'and stop pulleys 45, 45' and one end, which are respectively fixed to both ends of the shaft 43, and one end of the plurality of stop pulleys are respectively fixedly fixed to the inner pulley and the other end. While the guide pulleys 46, 46 ', 47, 47', which are condensed on the lifting pulleys 44, 44 'and the body 20, are turned, the lifting part expectations 31 It consists of wire ropes 48 and 48 'which are fixedly fixed to a predetermined position on the lower side.

Thus, the lifting portion 30 is installed in a state in which the bore 11 and the center of the base 20 are vertically coupled to be lifted by the wire ropes 48 and 48 ', and the base 20 and Guide rollers 50 and 50 'are provided on the upper and lower sides of the contact surface of the base 31 so that the base 31 can be smoothly lifted and lowered.

Referring to the operation state of the sedimentation lifting device according to the embodiment of the present invention configured as described above are as follows.

In order to lift the earth and sand settled in the settlement 10, when the motor 37 is driven with the lower end of the lifting part 30 lowered close to the floor, the chain gear 33 by the main shaft 32 ( 33 'is rotated so that the chains 34 and 34' are also rotated by the chains 35 and 35 'so that the chains 35 and 35' are in the direction of the arrow (A in FIG. Will be rotated to In this case, the buckets 36 installed between the chains 35 and 35 'are settled on the floor in the process of passing through the chain gears 34 and 34' on the lower side of the lifting portion 30 in turn. Will be put up.

In this way, the bucket 36, which continues to rise, is turned upside down when the chain gears 33 and 33 'of the upper side are notified, so that the contained sediment is poured and falls into the hopper 21 through the guide hopper 30'. It is sent by the hopper over the carry-out conveyor (12) to be taken out of the settling paper (10), the salvage is lifted by the repetition of this operation.

On the other hand, when the lifting portion is moved or the lifting portion is lifted due to no operation, the cylinder 40 of the elevating member is operated to raise the rod 41, and the lifting shaft 42 mounted on the upper end of the rod is The lifting pulleys 44 and 44 'are simultaneously raised because they are raised together.

Accordingly, the space between the lifting shaft 42 and the stop shaft 43 is widened, and the wire ropes 48 and 48 'are pulled up by the lifting lifting pulleys 44 and 44'.

In this case, since one end of the wire ropes 48 and 48 'is fixed to the inner pulley among the stop pulleys 45 and 45', the other end that is bound to the base 31 is finally pulled out. 30, as the rod 41 is raised, as a virtual line (B) as a whole rises vertically.

In addition, when the raised lifting portion 30 is to be lowered, when the cylinder 40 is reversed and the rod 41 is lowered, the lifting pulleys 44 and 44 'are also lowered, so the wire ropes of the pulleys are lowered. Lifting portion 30 is lowered by its own weight and the like because the force that pulls up (48) (48 ') is dissipated.

Of course, the degree to which the lifting portion 30 is lowered is determined according to the state to lower the rod 41.

In this way, the present invention settled lifting device, since the upper part of the settled area is open-air and is not bound by the installation height, the whole lifting part is installed to be vertically elevated by the action of the lifting means. There is an advantage that the structure of the whole machine becomes very simple.

In addition, the length change or spacing of the chain is not increased during the lifting operation, so that the breakage of the chain is eliminated and the life is extended, as well as the chain length is reduced and the manufacturing cost is greatly reduced to provide an economic lifting device. will be.
