Description

Drum rotation type feeder}

Unlike the existing spiral rotary feeder, the present invention is configured so that the drum itself rotates, thereby preventing entanglement of the fine powder, which is the object of transport, or breakage due to collision between the spiral and the fine powder, etc., thereby enabling transport while maintaining the uniform particle size of the fine powder. It relates to a drum rotary feeder that is possible and can ensure efficient operation of the device by enabling the design of a field-customized feeder by introducing an inlet/discharge means.

Typically, a feeder for transferring powder or fine powder has a fixed drum and rotates in a spiral to transfer the powder or fine powder, or uses a conveyor or the like.

In particular, in the case of the existing spiral rotary feeder, the drum is fixed and only the spiral provided inside the drum rotates to transfer the powder or fine powder. In this case, the rotating force of the spiral causes agglomeration between the powder or fine powder. There is a problem in that the particle size changes due to causes such as powder or fine powder being broken due to collision with the spiral, making it difficult to maintain a uniform particle size.

Accordingly, there is an urgent need for the development of a feeder with a sealed structure while maintaining a uniform particle size during transfer of powder or fine powder.

That is, a driving unit 20 is provided at one end of the drum 10 to transmit power, and a bracket is provided at the other end of the drum 10 to support the rotation of the drum 10. In addition, a spiral 11 is formed on the inner peripheral surface of the drum 10, so that when the drum 10 rotates, the object to be transported can be transported in the transport direction by the spiral 11.

In a conventional feeder, the drum 10 is fixed and only the spiral 11 provided inside the drum 10 rotates to transfer the object to be transported. In this case, the spiral 11 and the object to be transported, especially in the case of fine powder, Due to the rotational force of the spiral 11, the particle size changes due to causes such as entanglement between the fine powders or the fine powders break due to collision with the spiral 11, making it difficult to maintain a uniform particle size.

In order to solve this problem of the existing feeder, in the present invention, the drum 10 itself is rotated to transfer the object through the spiral 11 formed on the inner peripheral surface of the drum 10. In this way, when transferring objects, especially fine powder, through the rotation of the drum 10 itself, collision between the spiral 11 and the fine powder can be alleviated. In addition, this makes it possible to transport the fine powder while maintaining a uniform particle size by suppressing the phenomenon of agglomeration or breakage of the fine powder.

Additionally, since the object to be transported is transported through the inside of the drum 10, it can have an advantage over existing feeders in that it can ensure airtightness for the object to be transported, such as fine powder.

As shown in FIG. 1, the driving unit 20 according to the present invention is disposed on the other side of the drum 10 and is configured to rotate the drum 10.

The driving unit 20 for this purpose is connected to the driving motor 21 disposed on the other side of the drum 10 and the spiral 11 at one end of the drum 10, and transmits the driving force of the driving motor 21. It is configured to include a drive shaft 23 for rotating the drum 10.

In this case, the drive unit 20 can be implemented in various forms. First, the drive motor 21 is provided on the other end of the drum 10 and fixed by the mounting bracket 27, and the motor shaft of the drive motor 21 It can be configured to be directly connected to the drive shaft 23 so that the power of the drive motor 21 is transmitted to the drive shaft 23, thereby rotating the drum 10.

In another implementation example, a pulley is connected to the motor shaft of the drive motor 21, a pulley is connected to the end of the drive shaft 23 connected to the spiral 11, and each pulley may be connected to a drive chain. Therefore, when the drive motor 21 is driven, the drive shaft 23 rotates in conjunction with it, and at the same time, the drum 10 also rotates.

Regardless of how the drive unit 20 is configured, the drive shaft 23 connected to the spiral 11 can be manufactured to a predetermined length and connected to a certain portion of the spiral 11 at one end of the drum 10. there is.

Additionally, first and second cylindrical supports 14 in which the ends of the drum 10 are built are provided at one end and the other end of the drum 10, respectively. The first support 12 disposed at one end of the drum 10 has a hopper 30 disposed on the upper portion, and a first support bracket 13 is provided at the lower part of the first support 12 to provide a first support ( 12) is supported. A side plate is provided on one side of the first support body 12 so that the end of the support shaft 25 penetrates and is exposed to the outside. In this case, a support member such as a bearing for supporting the support shaft 25 is mounted on the side plate. It can be.

In addition, the other end of the drum 10 is provided with a drive shaft 23 connected to some spirals 11 disposed on the other side of the drum 10. In this case, the drive shaft 23 penetrates the side plate of the second support 14 disposed at the other end of the drum 10 and is exposed to the outside, and is attached to the other side of the drum 10 to support the end of the drive shaft 23. A second support bracket 15 is provided at the lower part. In this case, a support member such as a bearing for rotationally supporting the end of the drive shaft 23 may be mounted on the top of the second support bracket 15.

Additionally, the second support body 14 may be fixed to the second support bracket 15, and the discharge portion 40, which will be described later, may be disposed on the second support body 14.

As shown in FIG. 1, the hopper 30 and the discharge unit 40 according to the present invention are provided at one end and the other end of the drum 10, respectively, to enable input and discharge of the transported object.

First, the hopper 30 is disposed on one end of the drum 10, that is, on the upper part of the first support 12 to which the one end of the drum 10 is coupled, and is configured to allow the transfer object to be introduced into the drum 10.

Next, the discharge unit 40 is formed at the other end of the drum 10, that is, at the side or bottom of the second support 14 to which the other end of the drum 10 is coupled, and is formed on the object transported by the drum 10. It is configured so that it can be discharged to the outside.

As shown in Figures 1 to 3, the input/discharge means 50 according to the present invention is disposed at at least one point along the longitudinal direction of the drum 10 to enable input or discharge, or input and discharge, of the transfer object. It is configured to do so.

Typically, in silos or storage facilities where transfer objects are stored, the input location of the transfer object may be arranged at various points, and the discharge location of the transfer object may also be arranged in various ways.

Therefore, in the present invention, the drum 10 manufactured to a certain length is cut at an appropriate position, and the input and discharge means 50 are placed on the cut portion to enable input and discharge of the conveyed object.

This inlet/discharge means 50 is formed by cutting the drum 10, surrounds the plurality of cut ends 51 spaced apart from each other, the space between the cut ends, and the cut ends 51, and can be separated from each other. A housing 52 formed to do so, a first seal spiral 53 formed on one of the cut ends 51 and disposed in the same direction as the spiral direction of the spiral 11, and It is formed at the other cut end and includes a second seal spiral 54 disposed in a direction opposite to the spiral direction of the spiral 11.

First, the inlet/discharge means 50 cuts an appropriate point of the drum 10 to form spaced apart cut ends 51. At this time, the spiral 11 remains uncut at the part where the drum 10 is cut. In this case, the power transmitted by the driving unit 20 can be transmitted by the spiral 11 at the cut portion, but in this case, there is a risk of overloading the spiral 11, so the drum 10 is spaced apart including the cutting point. ) It is desirable to introduce a connecting shaft 55 having a certain length and fix it to the spiral 11 at the cutting point by welding or the like.

Since the plurality of cut ends 51 formed as described above are spaced apart from each other and the spiral 11 is exposed to the outside, a housing 52 that can be separated from each other may be provided. This housing 52 includes a first housing 52a disposed at the bottom, a second housing 52b disposed at the top and connected to the first housing 52a, and first and second housings 52a and 52b. ) and a coupling portion 52c formed to correspond to each other, and an annular edge portion 52d formed at both ends of the first and second housings 52a and 52b.

In this case, the first and second housings 52a and 52b have a roughly semicircular cross-sectional shape, and the upper end of the first housing 52a and the lower end of the second housing 52b are joints that protrude outward. (52c) is provided. The coupling portion 52c is fastened using a fastener such as a bolt, and is configured to allow the second housing 52b to be separated if necessary.

Accordingly, the first and second housings 52a and 52b include each cut end 51 and are formed to surround the space where the drum 10 is spaced apart. In addition, an auxiliary discharge port may be provided at the lower part of the first housing (52a), and the auxiliary input portion may be formed in the second housing (52b), or may be installed separately by separating the second housing (52b) from the first housing (52a). It is also possible to use the auxiliary input unit coupled to the first housing (52a).

In particular, in the input and output means according to the present invention, the space between the cut ends 51 and each cut end are covered by the first and second housings 52a and 52b, but the drum 10 itself rotates. A certain gap must be formed between (10) and the inner surface of the housing (52) so that they do not contact each other. However, in this case, the object transported by the spiral, especially fine powder, may be discharged through the gap between the drum 10 and the housing 52. To prevent this, in the present invention, a sealing function is provided at each cut end 51. Seal Spiral (11) is being introduced.

That is, the seal spiral 11 is composed of the first and second seal spirals 54. Based on the attached illustration of FIG. 2, the first seal spiral 53 is formed on the outer peripheral surface of the cut end 51 disposed on the right side. And the second seal spiral 54 is formed on the outer peripheral surface of the cut end 51 disposed on the left side. In this case, the first seal spiral 53 is formed in the same direction as the spiral 11 of the drum 10, and the second seal spiral 54 is formed in the opposite direction to the spiral direction of the drum 10. . Therefore, the first seal spiral 53 rotates in the same direction as the spiral 11 of the drum 10, and the second seal spiral 54 rotates in the opposite direction to the rotation direction of the spiral 11 of the drum 10. It rotates relative to the other.

That is, the transfer object is transferred in the transfer direction by the first seal spiral 53, and the transfer object is transferred in the opposite direction to the transfer direction by the second seal spiral 54, creating a gap between the drum 10 and the housing 52. The transfer object may be blocked from escaping through the gap.

Additionally, edge portions 52d that protrude inward may be formed at both ends of the first and second housings 52a and 52b, respectively. This edge portion 52d blocks the gap between the drum 10 and the drum 10 at both ends of each housing 52, thereby preventing the discharge of the transported object or the inside of the housing 52 or drum 10 from dust or other foreign substances from the outside. It is also desirable to block the inflow into the .

Meanwhile, the inlet/discharge means 50 according to the present invention is provided with an auxiliary discharge portion 60, which is formed in the lower part of the first housing 52a as described above, and this auxiliary discharge portion 60 is opened and closed as necessary. It is preferable that it is configured to be opened and closed by the opening and closing means 70 so that it can be opened and closed.

For this purpose, as shown in FIG. 3, the opening and closing means 70 is rotatably connected to an extension part 71 extending from the auxiliary discharge part 60 and the inside of the extension part 71 to open the extension part 71. An actuator ( 75).

The opening and closing wings 72 of the opening and closing means 70 are connected to a rotating shaft 76 so as to be rotatable, and both ends of the rotating shaft 76 are installed on the inner surface of the extension portion 71. In addition, the connecting member 73 is connected to the rotating shaft 76 and its end is hinged with the operating rod 74, allowing the connecting member 73 to rotate when the operating rod 74 is pulled in and out by the actuator 75. It is configured to do so. In this case, the actuator 75 may be composed of a cylinder, and the operating rod 74 may be composed of a piston rod provided in the cylinder. However, the actuator 75 can also use a driving body such as a motor in addition to the cylinder.

In this way, when the opening and closing wing 72 is rotated by the opening and closing means 70 and maintained in the horizontal direction based on the attached Figure 3, the extension part 71 is closed and the transfer object is not discharged. Conversely, when the actuator 75 is operated to rotate the opening and closing wings 72 at a certain angle from the horizontal state, the extension portion 71 is opened and the transported object can be discharged.

In this case, stop protrusions 77 protruding inward may be provided on both sides of the inner wall of the extension portion 71 to control the rotation of the opening and closing wings 72. Therefore, when the opening and closing wings 72 are rotated, if they are arranged in the horizontal direction, both ends of the opening and closing wings 72 may be caught by the stop protrusions 77, thereby preventing rotation. As a result, the rotation range of the opening and closing wings 72 may be limited to 180 degrees by the stop protrusion 77.

Figure 4 shows an application example in which the drum 10 rotary feeder according to the present invention is installed.

That is, the drum 10 rotary feeder can be mounted on the upper part of the mounting device 1 and arranged in multiple rows, as shown in Figure 4 (a). In this case, the hopper 30 may be provided on the right end side of the drum 10, and the drive unit 20 may be placed on the left end side.

In this case, the holding device 1 is provided with a storage portion 3 for accommodating the transfer object discharged from the feeder. The transfer object discharged from the feeder is not only at the end of the feeder, but also at the point where the inlet/discharge means 50 is formed. It is structured so that discharge can occur. That is, in the case of the feeder disposed in the second row at the top in (a) of Figure 4, two input and discharge means 50 are installed on the left side of the entire feeder, and in some cases, one or none may be installed. . Therefore, in the drum 10 rotary feeder according to the present invention, the input and discharge means 50 can be custom-made and applied so that they can be installed as needed depending on the actual site where the feeder is applied.

As such, the present invention has been described with reference to an embodiment shown in the drawings, but this is merely illustrative, and various modifications and other equivalent embodiments can be made by those skilled in the art. You will understand.
