[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for treating powder such as paper powder, wood powder (scraps), and plastic dust generated during cutting work, and particularly a dust press for compressing collected powder and discharging it into a solid state. Regarding the device.

[0002]

[Prior art]

 A conventional dust collector will be described with reference to FIG. The dust collector 1 has a fan 3 which is driven to rotate by a motor 2, and the rotation of the fan 3 sucks the air in the room such as a factory into the dust collector 1. The dust collecting device 1 is provided with a duct 4 for sucking indoor air and carrying it into the device. Further, a filter 5 is formed at the subsequent stage of the duct 4, and the powder in the air sucked by the duct 4 adheres to the filter 5 without passing through the filter 5. The air from which the powder has been removed is discharged to the outside of the dust collector 1 through the filter 6 and the discharge port 7 formed in the subsequent stage of the fan 3.

Further, the filter 5 is provided with a filter blower (not shown) for removing powder adhering to the filter 5 by vibrating the filter 5. The filter is operated by moving the handle 8 projecting outside the dust collector 1 up and down. Further, in the dust collector 1, a bucket 9 is formed below the filter 5 for collecting the powder removed from the filter 5 by the action of the filter striking. The bucket 9 is of a pull-out type that can slide back and forth.

Next, the operation and action of this dust collector will be described. By rotating the fan 3 with the motor 2, the air in the room such as a factory is sucked into the dust collector 1 through the duct 4. The sucked air passes through the filter 5, but the powder adheres to the filter 5, and the air and the powder are separated. The passed air passes through the filter 6 provided at the exhaust port 7 and is discharged to the outside of the dust collector 1. When the dust collector 1 is operated for a certain period of time, a certain amount of powder is deposited on the filter 5. When a predetermined amount of powder is accumulated, the operator stops the rotation of the motor 2 and stops the suction of air.

Next, the operator moves the filter stroke handle 8 up and down to operate the filter stroke. The powder accumulated on the filter 5 is removed from the filter 5 by the operation of tapping the filter. The removed powder is guided to the shooter 10 and collected inside the bucket 9. After that, the bucket 9 is pulled out forward, the powder stored in the bucket 9 is taken out, and the bag is packed. Then, the packed powder is finally incinerated or the like.

[0006]

[Problems to be solved by the device]

 The conventional dust collector has a problem that powder is scattered and re-contaminates the environment when the powder is taken out of the bucket and packed in a bag. To improve this, the dust pack is stored in a bucket, and when the powder is taken out from the bucket, the dust pack is collected and discarded. In the case of using a dust pack, the problem of secondary pollution of the environment can be solved to some extent, but the cost of the dust pack itself is high and the dust itself contains air even though the amount of powder itself is small There was a problem that the pack was bulky and required a considerable storage space for incineration of the dust pack.

The present invention prevents the recovered powder from scattering again and prevents secondary pollution of the environment, and also compresses and solidifies the recovered powder to reduce its volume, thus making effective use of storage space. It is an object of the present invention to provide a dust press device that can be used for various purposes and that can incinerate powder easily.

【Example】

 An embodiment of the present invention will be described with reference to FIGS. The dust press device according to the present invention can be easily attached to the lower part of the dust collector 1 by removing the bucket portion 9 of the conventional dust collector 1 shown in FIG. That is, except that the conventional bucket 9 for collecting powder in the dust collector 1 is eliminated and the powder can be carried into the press device 11 by the chute 10 formed in the lower portion of the filter 5. Since the dust collector is used as it is, the explanation of the dust collector itself is omitted.

The pressing device 11 according to the present embodiment has a powder storage unit (powder storage chamber) 12, and the powder guided by the chute 10 is stored on the upper surface of the powder storage unit 12. A powder carry-in port 13 for carrying in 12 is formed. A shutter 15 which is openable and closable is formed at the powder carry-in port 13, and the shutter 15 is opened and closed by a shutter control cylinder 14. The tip portion 15a of the shutter 15 has a sawtooth shape and is configured to engage with the upper edge of the front side wall of the powder container 12.

A powder compression cylinder 16 is slidably attached to one side of the powder container 12 in the powder container 12. The rod of the powder compression cylinder 16 is provided with a pressing piston 17. The powder compression cylinder 16 and the pressing piston 17 form a powder compression means and a solidified powder discharge means.

Further, a gate 18 that can be moved up and down to discharge the powder is formed on the side opposite to the one side of the powder storage unit 12 to which the powder compression cylinder 16 is attached. The gate 18 is driven by a gate control cylinder 19.

A mounting table 20 for mounting the solid powder discharged from the pressing device 11 is provided outside the gate 18. The upper surface of the mounting table 20 is adjusted to be substantially flush with the inner bottom surface of the powder storage chamber 12, and when the solidified powder 21 is discharged from the powder storage chamber 12, the powder is impacted. Is taken into consideration.

Next, the control system of each cylinder will be described with reference to FIG. In order to automatically operate the above-mentioned press device 11, in this embodiment, the powder amount detection sensor 22 for detecting the powder amount in the powder storage chamber 12 and the powder carry-in port 13 in the storage chamber 12 are provided. A shutter open / close detection sensor 23 for detecting the open / closed state, a powder pressure detection sensor 24 for detecting the powder compression state by the powder compression cylinder 16, and a position for detecting the position of the powder compression cylinder 16. A detection sensor 25 and a sensor 26 that detects the position of the gate 18 are provided at predetermined locations. The outputs of the sensors 22, 23, 24, 25, 26 are input to the CPU 27, and the CPU 27 outputs a predetermined control signal to the cylinder control circuit 28 to control the operation of each cylinder 14, 16, 19.

The type of the detection sensor is not particularly limited as long as it is a sensor such as an optical sensor, a magnetic sensor, or a pressure sensor that can achieve the intended purpose.

Next, the operation and action will be described. As in the conventional case, the air in the room such as a factory is carried into the dust collector 1 through the duct 4 and removed by the filter 5. The dust-removed air is exhausted to the outside from the exhaust outlet 7 through the fan 3 and the filter 6. On the other hand, the powder adheres to the filter 5, and when the powder is deposited on the filter 5 in a predetermined amount, the filter striking handle 8 is operated to remove the powder from the filter 5. The removed powder is taken into the powder storage chamber 12 along the shooter 10 from the carry-in port 13 of the pressing device. At this time, the shutter 15 is open.

When the powder amount detection sensor 22 detects that a predetermined amount of powder has accumulated in the powder storage chamber 12 (t 1 in FIG. 4), the detection signal is output to the CPU 27. The CPU 27 receives the signal and outputs the signal to the cylinder control circuit 28 to operate the shutter control cylinder 14 and close the shutter 15 (t2 in FIG. 4). At this time, the tip end portion 15a of the shutter 15 formed in a sawtooth shape engages with the upper end portion of the front side wall of the powder container 12. Therefore, even if there is thread-like dust, the dust can be cut and the powder carry-in port 13 can be completely closed.

When the shutter is completely closed, the shutter open / close detection sensor 23 inputs a detection signal to the CPU 27, and the CPU 27 sends a control signal to the cylinder control circuit 28 to drive the powder compression cylinder 14. . When the powder compression cylinder 16 receives this signal and slides the rod to the right (t3 in FIG. 4), the shutter 15 and the gate 18 are closed, so that the powder is compressed by the pressing piston 17. . When compressed to a predetermined pressure, the powder pressure detection sensor 24 sends a detection signal to the CPU 27. In order to solidify the powder, the CPU 27 does not directly send a signal to the cylinder control circuit 28, but sends a control signal to the cylinder control circuit 27 with a delay for a certain time.

When a backward signal is input from the CPU 27 to the cylinder control circuit 28 to the powder compression cylinder 16 after a lapse of a predetermined time, the rod of the piston 16 slightly slides to the left in response to the signal (Fig. 4 t4). The sliding of the cylinder 16 to the left is to facilitate the opening operation of the gate 18. That is, when a predetermined pressure is applied to the powder by the cylinder 16, the pressure also acts on the gate 18 and hinders the opening operation of the gate 18.

When the powder compression cylinder position detection sensor 25 detects the position of the cylinder 16 retracted to the left, the detection signal is output to the CPU 27, and the CPU 27 receives the detection signal and opens the gate 18 to control the cylinder control circuit. Control signal is sent to 28. A drive signal is input from the cylinder control circuit 28 to the gate control cylinder 19 to open the gate 18 (t5 in FIG. 4).

When the gate position detecting sensor 26 detects that the gate 18 is completely opened, the detection signal is sent to the CPU 27. In the CPU 27, the powder compression cylinder 16 is slid rightward again to discharge the solidified powder to the outside, so that a control signal is sent to the cylinder control circuit 28 (t6 in FIG. 4).

In response to the signal, the powder compression cylinder 16 moves to the right and pushes the solidified powder from the powder storage chamber 12 onto the mounting table 20 outside. At this time, since the mounting table 20 is adjusted to have the same height as the powder storage chamber 12, the impact at the time of discharging can be minimized and the solidified powder 21 is prevented from being deformed. is doing.

When the powder compression cylinder position detection sensor 25 detects that the powder compression cylinder 16 has moved a predetermined distance and the solidified powder 21 has been discharged, the signal is sent to the CPU 27. Upon receiving the signal, the CPU 27 sends a control signal to the cylinder control circuit 27 to slide the powder compression cylinder 16 to the left and restore the initial state (t7 in FIG. 4).

Further, when the powder compression cylinder position detection sensor 25 detects that the powder compression cylinder 16 has returned to the initial state in response to the control signal, the detection signal is sent to the CPU 27, and the shutter 15 and A control signal is sent from the CPU 27 to the cylinder control circuit 28 to restore the gate 18 to the initial state (t8 in FIG. 4).

When the shutter open / close detection sensor 23 detects that the shutter 15 has been opened and the gate position detection sensor 26 has detected that the gate 18 has been closed, these detection signals are sent to the CPU 27, respectively, and the entire device is initialized. It returns to the state (t9 in FIG. 4).

In the embodiment of the present invention, the filter presses the powder removed from the filter, but the dust pressing apparatus according to the present invention uses the filter hit like a cyclone dust collector. Of course, it can also be applied to those that can separately collect air and dust. In this case, the filter does not need to stop the fan as in the case of operating the fire, and continuous and complete automation can be achieved. When the powder has little moisture and is hard to solidify, water, oil, etc. may be atomized and ejected into the storage chamber, and then the powder may be compressed and solidified by the compression cylinder. In the above-described embodiment, the amount of powder in the powder storage chamber is detected by the sensor, but a predetermined time may be detected by a timer or the like and a predetermined operation may be performed. You may go. The solid powder (flammable material) discharged from the dust press device of the present invention can be used as a solid fuel by impregnating oil.

[0028]

As described above, according to the present invention, the powder can be solidified and discharged, and the conventional work of packing the dust stored in the bucket is not only necessary. It is possible to prevent the powder from scattering at that time. Further, since it is solidified, the space to be stored for subsequent incineration and the like can be reduced as much as possible, and the processing such as incineration becomes easy.
