Description

[Detailed Description of the Invention] This invention is a method for loading objects containing fine dust, such as powder such as dirt and sand, or lumps such as pebbles, onto a tank truck such as a vacuum dumper truck by pneumatic transportation. The present invention relates to a dust collection device that is used in conjunction with a pneumatic transportation device, particularly for removing damage caused by dust on the pneumatic transportation device.

Conventionally, when loading powder and the like onto a vacuum damper vehicle, the main method was to attach a vacuum pump to the vacuum damper vehicle itself, apply negative pressure to the damper chamber, and use a vacuum suction method.

The vacuum suction method normally transports the transported object from the supply side to the supplied side (damper chamber of a vacuum damper vehicle) using water as a medium. In connection with this, the amount of water as a medium increases rapidly, and the amount of water occupying the damper chamber is significantly larger than the transported material, and even if the water is drained sequentially by overflow, the water and Separation of the objects to be transported did not occur as expected, making it difficult to obtain the desired amount of cargo to be transported.

Additionally, if the distance from the supply side to the damper room is long or there is a significant height difference, the water in the hose connecting the two places a burden on the vacuum pump, reducing suction power and reducing work efficiency. At the same time, the performance of the vacuum damper vehicle deteriorated, and there were limits to its applicability.

Therefore, the present inventor first developed a pneumatic transport system that improves and eliminates the above-mentioned conventional drawbacks by transporting objects by air, and improves the work efficiency and performance of this type of transport device.
The system was developed and its effectiveness was far superior to that of conventional devices of this type.

By using the present invention between the pneumatic transport device and the vacuum damper vehicle, the present invention prevents dust from flowing into the pneumatic transport device from the vacuum damper vehicle. It is an object of the present invention to provide a device that protects the above-mentioned pneumatic transportation device and further improves its performance.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the structure of the present invention shown in the drawings will be described below.

In Fig. 1, 1 is a vacuum in which a pneumatic transport device consisting of a dust remover A1, a silencer B, C, a vacuum pump D1, an independent engine part E, a hose winding device F1, an exhaust device G, etc. is mounted on the body of a truck or the like. 2 is a pump truck, 2 is a dust collector according to the present invention, and 3 is a vacuum damper truck having a damper device H.

As shown in FIGS. 2 and 3, the dust collector 2 according to the present invention has a separation chamber 4 and a separation chamber 4 for separating dust and air carried from the vacuum damper H through the suction port 5. It consists of a collection tank 12 that collects the separated dust.

The separation chamber 4 has a cylindrical shape, and its side is provided with an inlet 5 for sucking air and dust from the vacuum damper H, and the upper surface is provided with an inlet 5 for sucking air and dust from the vacuum damper H, and a dust removal device of the air transport device is provided on the top surface of the separation chamber 4. A discharge port 6 for sending the water to A is provided.

Inside the separation chamber 4, a cylinder 7 having a larger diameter than the discharge port 6 is provided inside the upper surface of the separation chamber 4 to form a cyclone (2).

A baffle plate 8 is supported and fixed at the center of the cylinder 7 by a support member 9, and by providing this baffle plate 8, separation by a cyclone (2) to be described later is made more complete.

10 is a cleaning port with a viewing window, and 11 is a cleaning port.

A collection port 13 is provided at the top of the collection tank 12 connected to the lower side of the separation chamber 4 to collect the dust separated by the cyclone (2) of the separation chamber 4. A water tank 12a is provided at the bottom.

The cleaning water in the water tank 12a is sucked up by the air flow sucked into the separation chamber 4 from the suction port 5, becomes atomized by the ejector action, comes into contact with the dust in the air flow, increases the density of the dust, and creates a cyclone. This is to make the separation of air and dust more effective in step 1.The tip port 23a of the cleaning water nozzle 23 connected to the water tank 12a is inserted into the suction port 5 to make the air flow more effective. Spraying is being carried out. In addition, a buffer plate 21 is provided in the water tank 12a, and the separation chamber 4 is connected to the water tank 12a.
Dust and water are separated from the dust-containing water collected in the air by the one-way overbuffing port of the buff-full plate 21, and the separated cleaning water is used again for spraying into the air flow. It uses a circulation method.

In addition, the collection tank 12 has a water supply port 14 for washing water to the water tank 12a, cleaning ports 15 and 16 with viewing windows, and a hatch-type cleaning port 1.
7, 18, rubber wheels 20 for moving the dust collector 2, a water level gauge 22, etc. are installed in the exhaust cot 19A for discharging dirty wash water and dust.

Incidentally, the power source of the dust collector 2 configured as above, that is,
The pneumatic transport force that sucks dust from the vacuum damper H, separates the dust and air, and discharges the air purified by the separation to the dust removal device A of the pneumatic transport device is generated by the rotary set vacuum equipped in the pneumatic transport device. It is obtained by pump D.

To explain the operation of the dust collector according to the present invention, the dust sucked into the separation chamber 4 by the vacuum pump D is first collected at the suction port 5.
The dust that has become hydrated and has increased density by the spray from the cleaning nozzle 23 is transferred to the third separation chamber 4 by the cyclone ■.
It is rotated as shown in the figure.

Then, the dust with increased density falls while being rotated and flows through the collection port 13 into the water tank 12a of the collection tank 12.
will be collected.

The air that has been separated from dust and purified by the cyclone ■ is discharged from the exhaust port 6 to the dust removing device A of the air transport device.
After colliding with the baffle plate 8 provided in the center of the discharge port 6
be carried to.

Therefore, the residual dust slightly contained in the purified air is completely removed by the baffle plate 8, and the air carried into the dust removing device A contains almost no dust.

In addition, the water-containing dust collected in the water tank 12a is collected in the water tank 12a.
It settles and accumulates at the bottom of the tank.

The cleaning water recovered together with the dust is then used as cleaning water via the nozzle 23 again by an overflow method by the cleaning water drain plate 21.

Next, the operation (transportation) procedure of the pneumatic transportation device using the dust collector 2 according to the present invention will be explained.

First, when the independent engine part E is operated to rotate the rotary vacuum pump D, the suction force of the pump causes the vacuum pump D to flow from the suction part Ha of the vacuum damper device H to the dust collector 2, dust remover A1, and silencer B. An air flow is formed that flows towards the area (arrow in Figure 1).

Further, this air flow is exhausted by the discharge force of the vacuum pump D through the muffling device C1 and the exhaust device D.

Taking as an example the case where the object to be transported is sand, the sand is sucked up from the suction part Ha of the vacuum damper device H and sucked into the vacuum damper device H, and air and sand are separated by a predetermined method. Moreover, most of the sand is separated here.

The separated air is transferred to the inlet 5 of the dust collector 2 according to the present invention.
However, this inhaled air still contains a small amount of sand and dust.

This air is sprayed with cleaning water by the cleaning nozzle 23 as described above to make the dust and residual sand hydrated, and then the separation chamber 4
Air and dust are separated by the cyclone I and the baffle plate 8 inside, and the air is almost completely purified by the dust collector 2.

The purified air is then conveyed to the dust remover A through the exhaust port 6, where it is made into completely clean air using a predetermined method, and is discharged to the outside of the air transport device via the vacuum pump D. .

The operation procedure has been explained above, but since the air that has been almost completely purified by the dust collector according to the present invention that uses both a wet type and a cyclone is further completely purified by the dust remover A, the air that flows into the vacuum pump D does not contain dust, and thus the vacuum pump D is prevented from degrading its functionality and shortening its life due to the incorporation of dust.

Further, since the dust collector 2 according to the present invention has a simple structure, it is very easy to clean and hardly needs to be cleaned.

As explained above, the present invention includes a dust removal device, a noise reduction device, a vacuum pump driven by an independent engine, a noise reduction device, an exhaust device, etc., and connects the dust removal device to the suction side of the vacuum pump via the noise reduction device. , a vacuum pump truck having an exhaust device connected to the discharge port side of the vacuum pump via a silencer, and a vacuum tank connected to the vacuum pump of the vacuum pump truck via a hose via a dust remover, and This is a dust collection device installed between a vacuum damper vehicle and a vacuum damper vehicle that sucks in transported objects such as dust and earth from a hose along with air and separates and collects them in the tank, and has a hose connected to the vacuum tank on the side. It has an air inlet on the top surface that is connected to the dust remover of the vacuum pump vehicle with a hose, and has a central part concentric with the air outlet that indirectly directs the air from the air inlet to the air outlet. A cylindrical separation chamber in which a cyclone is formed by providing a cylinder with a larger diameter than the discharge port on the inside of the upper surface, which has a baffle plate for the discharge to flow out to the discharge port; A collection tank having a water tank at the bottom for collecting the dust separated in the chamber, and a collection tank connected to the suction port of the separation chamber so that the cleaning water in the water tank is hydrated to the dust in the suction port.
