Description

Tube Forming Equipment {EQUIPMENT FOR MOLDING CONCRETE-POLYMER TUBE}

The present invention relates to a tube forming apparatus, and more particularly, to a tube forming apparatus that can be used for molding concrete polymer tubes and the like, and is easy to supply raw materials for forming a tube and to produce high quality tubes. .

Generally, water pipes such as water, sewage pipes, and drainage pipes are used for securing waterways by being buried to a certain depth from the surface of the water, and are molded by injecting raw materials such as concrete or synthetic resin into the pipe-shaped molds. The manufactured concrete pipe or synthetic resin pipe is mainly used.

The water pipes are not only durable to withstand loads and vibrations, but also require watertightness to reduce fluid loss due to leakage after installation in the ground. The synthetic resin pipes are easily molded and have excellent watertightness and chemical resistance. However, there is a disadvantage in that the durability against shock or vibration is weak, and the concrete pipe is relatively strong in durability than the synthetic resin pipe, but has a disadvantage in that satisfactory watertightness and chemical resistance are not maintained.

In recent years, so-called polymer tubes are used to compensate for the shortcomings of the synthetic resin pipes and concrete pipes, and these polymer pipes are formed of raw materials in which additives such as polymers are mixed in aggregate, and a coating layer is formed on the inner or outer circumferential surfaces of the molded pipes. As a result of the formed structure, as compared with conventional synthetic resin pipes or concrete pipes, as well as durability and improved watertightness, chemical resistance and the like can be obtained.

As a representative apparatus for molding the polymer tube, there is a patent registration No. 0346076, filed in 2001 and registered on July 08, 2003.

However, the conventional pipe forming apparatus has a structure in which the raw material supplied to the raw material supply part is provided with a common hopper having a single passage on the raw material inlet side and is supplied while the raw material falls through the passage of the hopper, so that the raw material, that is, aggregate For example, the aggregates contained in the edge region are pushed by the inner wall surface of the hopper due to the aggregate pressure in the central region of the passage, and have a slower falling speed than the aggregates in the central region. This causes a problem that the smooth supply of the raw material is not made.

In addition, when stagnant phenomena occur according to the location contained in the hopper passage as described above, aggregates are aggregated to a similar size and dropping occurs, and thus, when mixing raw materials, mixing with additives such as polymer is not performed smoothly. In addition, the surface of the molded tube, as well as the polymer layer is not formed uniformly, which is a factor that reduces the quality of the tube.

The length of the raw material conveying part 8, that is, the conveying pipe 18a, moves smoothly in the longitudinal direction of the molder 38 of the molding apparatus 4, which is described later, by which the raw material discharging part 10, which will be described later, moves along the trolley 6. It is made within the range that can be moved, but not shown in the drawing, the diameter of the transfer pipe 18a may be manufactured in a form that gradually decreases from the inlet side to the outlet side.

In addition, the screw 18b installed inside the transfer pipe 18a is connected to a drive source M2 such as a motor so as to transmit power as shown in FIG. 1, and the drive tube M2 is driven by the drive source M2. 18a) the aggregate can be transported by rotation in the inner region.

At the distal end of the raw material conveying part 8, a raw material discharging part 10 for mixing the transported aggregate with an additive or the like and discharging it to the molding apparatus 4 is installed. In the present embodiment, the raw material discharge part 10 is a housing 20 in which aggregate is contained as shown in FIGS. 3 and 4, and a stirring shaft disposed inside the housing 20 to mix and discharge the aggregate and the additive. An example consisting of (22) is shown.

The housing 20 is manufactured in the shape as shown in FIG. 3 so that the aggregate supplied from the raw material transfer part 8 is contained, and the upper region has a structure in which the opening 20a is formed as shown in the drawing.

The stirring shaft 22 is formed on the outer circumferential surface of the blade 22a in the same shape and arrangement as in FIG.

In addition, the additive mixed with the aggregate in the housing 20 may be a polymer and a curing agent. These additives are made to be supplied to the inside of the housing 20 through a nozzle box (N) installed at the distal end of the conveying pipe (18a) of the raw material conveying section 8, as shown in Figure 4, the supply of these additives It can be supplied to the nozzle box (N), for example, by pumping of the pumping device contained in the additive reservoir (B) installed in the cart (6).

At this time, the mixing ratio of the aggregate and the additives mixed in the housing 20 may be made in the range of 75 to 90% by volume, 10 to 25% by volume of polymer, 0.5 to 2% by volume of the curing agent, such a mixing ratio in the tube to be molded It can be changed in an appropriate ratio to satisfy the required durability, watertightness and the like.

The polymer is produced and sold by Aekyung Chemical Co., Ltd., and a polymer having a brand name "POLY COAT" is used. As the curing agent, a conventional curing agent widely used for pipe forming or the like may be used.

In the above-described embodiment, the polymer and the curing agent are mixed as an example, but the nitrogen may be further mixed as an additive.

Although the supply of nitrogen is not shown in the drawing, for example, by supplying the polymer and the curing agent, for example, by creating an atmosphere for blocking the oxygen present in the mixed region of the raw material, that is, the inner region of the housing 20. In the raw material discharge part 10, when the aggregate, the polymer, and the curing agent are mixed, the mixed raw material may be prevented from premature curing by chemically reacting with oxygen.

On the other hand, the raw material inlet side of the raw material transfer unit 8 is provided with a raw material supply unit 12 as shown in FIG. 1 so that the aggregate is supplied to the raw material transfer unit 8 through the raw material supply unit 12.

5 to 6, the structure of the raw material supplier 12 is described in detail as follows.

The raw material supply unit 12 is located in the hopper 24, the guide plate assembly 26 for dividing the hopper 24 inner region into a plurality of passage regions, and in the lower region of the guide plate assembly 26. Opening and closing portion 28 for blocking or opening the passage of the hopper 24 and a stirring portion 30 is located in the lower region of the guide plate assembly 26 to agitate the aggregate.

The hopper 24 is for guiding the supply of aggregate. In the present embodiment, the hopper 24 has a structure in which a rectangular passageway region is provided as shown in FIG. The one installed in the same posture is shown as an example.

And, when the hopper 24 is installed on the raw material inlet side of the raw material transfer part 8 to support the hopper 24 as shown in FIG. A separate supporter 24a may be installed in a posture supporting the hopper 24 as shown in the drawing.

The guide plate assembly 26 partitions the inner region of the hopper 24 to a certain area and allows aggregate to be supplied to the raw material transfer part 8 through the partitioned regions. A single passage in the hopper 24 is divided into a shape as shown in FIG. 7 to provide a plurality of guide passages H as an example.

When the guide plate assembly 26 is installed inside the hopper 24 as described above, when aggregates are supplied to the single passage of the hopper 24, the guide passages H of the guide plate assembly 26 are as described above. By supplying uniformly by minimizing the interference between the falling aggregates, it is possible to uniformly supply aggregate while preventing the blockage of the aggregates in advance.

If the guide plate assembly 26 is not installed in the hopper 24 and only aggregate is supplied through a single passage, aggregates contained in the edge region by the pressure of the aggregates contained in the central region of the single passageway are provided in the passage. Since it is pressed on the wall, the aggregates in the central area receive relatively less interference when falling, so the falling speed is faster. Aggregates in the rim area have a problem of stagnation that stays stagnant at the wall surface of the passage by aggregates in the central area, thereby preventing the supply of smooth aggregates.

In addition, when the aggregate is contained through the inflow side of the hopper has a different drop speed according to the size of the aggregate, for example, because the small aggregate is contained in the central region and the large aggregate is contained in the border region Due to this, as well as to further increase the stagnation phenomenon of the aggregate, and when passing through the hopper, a similar phenomenon occurs that can be a factor that reduces the quality of the tube.

In the above, a single rectangular passage is formed inside the hopper 24 as shown in FIG. 7, and the passage is partitioned into a checkerboard shape as shown in the drawing by the guide plate assembly 26 as an example. It is not limited to this.

(H) may be formed of a structure formed. In addition, the guide passage (H) structure partitioned inside the hopper 24 may be formed in a plurality of circular or polygonal shapes partitioned into a predetermined shape by the guide plate assembly 26, although not shown in the drawing.

In addition, the plurality of guide passages H formed in the guide plate assembly 26 have a length of the guide passage H of the central region longer than the length of the guide passage H of the edge region, as shown in FIG. 6. Such a structure may prevent the aggregates falling through the partitioned guide passages H from gathering again in the lower area of the single passage of the hopper 24 so that interference between the aggregates occurs.

The opening and closing portion 28 is to allow the passage lower region of the hopper 24 to be opened or blocked. In this embodiment, as shown in FIG. 6, the two blocking plates 32 correspond to each other as shown in the drawing. Positioning in a posture is shown as an example.

It is a structure for opening or blocking the discharge-side passage of the hopper 24 by the open operation as described above.

The blocking plate 32 is set so that the opening and closing operation as described above is intermittently in a predetermined time difference range to control the supply amount of aggregate by opening or blocking the passage of the hopper 24 as well as the intermittent opening and closing. By the operation, physical vibrations or shocks are transmitted to the discharge side passage area of the hopper 24, thereby preventing the aggregates from falling off. The opening and closing operation of the blocking plate 32 may be performed by controlling the driving of the driving source M3 by a well-known electric control method although not shown in the drawing.

In the above description, the opening and closing portion 30 is formed of two blocking plates 32 and the passage of the hopper 24 is opened or blocked as they are collapsed or opened while being linearly moved. It doesn't happen.

As shown in FIG. 10, a blocking plate 32 capable of blocking a passage lower region of the hopper 24 is fixed to a shaft 34 connected to a driving source M3 such as a motor so as to transmit power, and the driving source M3. The shaft 34 is rotated by the rotational power of and may be configured to block the passage of the hopper 24 by the one blocking plate 32 or open as shown in FIG.

The stirring unit 30 is to be supplied while the aggregate supplied to the raw material transfer unit 8 on the discharge side of the hopper 24 is stirred, in the present embodiment as shown in Figure 13 the hopper 24 In one example, the shaft 36 is formed of a shaft 36 having a plurality of stirring protrusions 36a formed on an outer circumferential surface of the passage lower region, and is rotatably positioned in the lower region of the opening and closing portion 28 in the same posture as shown in the drawing.

The shaft 36 to which the stirring protrusions 36a are fixed is connected to a driving source M4 such as a motor so as to be capable of power transmission at one end as shown in FIG. 13, and the shaft 36 is driven by the driving source M4. It is a structure to stir the aggregate which falls while a) rotates. At this time, the stirring projections 36a protruding from the shaft 36 may be formed in a shape, size, and arrangement that can be smoothly discharged to the lower region as well as stirring the aggregate in addition to the structure shown in the drawing.

When the stirring unit 30 is installed as described above, aggregates falling through the passage of the hopper 24 are mixed more uniformly without agglomeration by size by the stirring operation of the shaft 36, and thus the raw material transfer unit 8 is mixed. Can be supplied.

In the above description, the opening and closing portion 28 and the stirring portion 30 are respectively provided in the description and the drawings corresponding to the area in which the aggregate falls in the hopper 24, but are not limited thereto.

For example, although not shown in the drawing, the aggregate is dropped in the guide passage H of the guide plate assembly 26 by installing only the stirring unit 30 in the discharge side region inside the hopper 24. 30) may be passed through the area as it is, stirred and supplied.
