Description

Description: TECHNICAL FIELD The present invention relates to a separator / drainer for an air transportation device that sucks and absorbs an object to be processed on an air stream.

[Conventional technology]

An air transportation device equipped in a vehicle will be described with reference to FIG.

The pneumatic transportation device includes a receiver tank (1) for storing an object to be processed (A) and a separator (2) for removing dust.
A vacuum pump (3) for generating an air flow, a draining device (4) for separating makeup water supplied to the vacuum pump (3), and a discharge silencer (5) for silencing, Each is connected in series by an air conduit (6). When the air transportation device is mounted on one vehicle, it is necessary to compactly pack it in a limited space. However, when the receiver tank (1) is downsized, the storage capacity of the object to be treated (A) is reduced. Therefore, the applicant has proposed that the separator (2) and the draining device (4) are integrated and serve as a separator and a drainer. The device (60) is disclosed in Japanese Patent Laid-Open No. 58-56937, which will be described with reference to FIG.

The separator / drainage device (60) is configured by dividing the inside of a closed main body (61) of a horizontally long cylinder into a separator (2) and a water draining device (4) by a partition plate (62).

An air conduit (6) communicating with the discharge side (3b) of the vacuum pump (3) is inserted between the partition plate (67) and the partition plate (62), and its exhaust opening (6c) is provided. Face the partition plate (62) with an appropriate gap. An exhaust pipe (68) communicating with the discharge silencer (5) is inserted through the other top plate portion (61a) partitioned by the partition plate (67). Furthermore, the device body (61)
A water tank (8) communicating with the discharge port (68) of the water draining device (4) is attached to the lower side of the water tank (8) and the suction side (3a) of the vacuum pump (3). It is connected by a water supply pipe (9).

Next, an operation procedure of the air transportation device including the separator / drainage device (60) will be described with reference to FIGS. 5 and 6.

First, the vacuum pump (3) is actuated, and from the hose (1a) to the receiver tank (1), separator and drainer (6
An air flow is generated through the separator (2) of (0), the vacuum pump (3), the drainer (4) of the separator / drainer (60), and the discharge silencer (5) to the atmosphere. This air flow causes a negative pressure to be generated in the water supply pipe (9) so that the makeup water in the makeup water tank (8) is sucked into the suction side (3) of the vacuum pump (3).
Suction from a) into the vacuum pump (3). Then, a water film is formed between the two Mayu-shaped rotors (not shown) rotating in the vacuum pump (3) and the casing of the vacuum pump (3), the airtightness between them is increased, and the suction force is increased. The frictional heat is eliminated and seizure is prevented. In this way, the tip of the hose (1a) is put into the object to be treated (A) while a strong air flow is generated. The object to be processed (A) becomes a mixed flow with air and is sprayed on the baffle plate (1b) in the receiver tank (1) and bounces back, whereby the object to be processed (A) is discharged from the receiver tank (1). It falls to the bottom and accumulates. However, a part of the fine particle-shaped object to be treated (A) flows out of the receiver tank (1) together with the air flow and flows into the separator (2) of the separator / drainage device (60). In the separator (2), fine particles of the object to be treated (A) flow from the exhaust opening end (6a) of the air conduit (6) to the top plate portion (61a) of the apparatus body (61).
And bounces off against the partition plate (63). Then, the fine particles of the object to be treated (A) fall into the water storage section (65),
It adheres to water and precipitates. Therefore, only the clean air from which the object to be treated (A) is completely separated and the makeup water from the makeup water tank (8) flow into the vacuum pump (3). The air containing makeup water is sent from the vacuum pump (3) to the draining device (4) of the separator / drainer (60), the makeup water collides with the partition plate (62), and is supplied from the discharge port (68). Water tank (8)
Return to inside. The air from which the makeup water has been separated flows into the discharge silencer (5) through the discharge port (68), the high frequency is absorbed, the sound is muted, and the air is discharged to the atmosphere.

[Problems to be Solved by the Invention]

Drainer (4) of conventional separator and drainer (60)
In the case of (1), the makeup water was made to collide with the partition wall water (62) for air-water separation, so that the makeup water could not be completely separated from the air.

Further, since the discharge silencer (5) is provided outside the separator / drainage device (60), miniaturization of the device was not sufficient.

Therefore, the present invention is capable of completely performing air-water separation,
Moreover, it is an object of the present invention to provide a further downsized separator / drainer for an air transportation device.

First, the vacuum pump (3) is driven to move the hose (1a) to the receiver tank (1), the separating device (7), the separator chamber (20) of the separator / drainer, the vacuum pump (3), the separator / drainer. An air flow flowing to the atmosphere is generated through the air / water separation chamber (30) with a muffler. This air flow causes a negative pressure to be generated in the water supply pipe (9), and the makeup water in the water tank (12) is sucked and supplied to the suction side (3a) of the vacuum pump (3), so that the vacuum pump (3) is supplied. inject.

In such a state, the object to be treated (A) is sucked from the tip of the hose (1a). The mixed flow of the object to be processed (A) and air is blown and bounces off the baffle plate (1b) in the receiver tank (1), whereby the object to be processed (A) falls to the lower part of the receiver tank (1). And deposit. And
A part of the object to be treated (A) flows out of the receiver tank (1) together with the air flow, and after a part of the object to be treated (A) is separated by the separating device (7), fine particles of the object to be treated (A) are separated. The slightly treated product (A) flows into the separator chamber (20) of the separator / drainer.

The air flow in which the fine particulate object (A) remains is blown from the inlet pipe (22) to the baffle plate (23) in the separator chamber (20), and the object (A) is air. It is completely separated from the flow and accumulated in the separator chamber (20), and only clean air flows into the vacuum pump (3) through the exhaust pipe (24). In the vacuum pump (3), the air flow containing makeup water supplied from the water tank (12) flows into the muffler-equipped air / water separation chamber (30) of the separator / drainer. The air flow containing makeup water is completely separated in the cyclone separator (31) of the air / water separation chamber (30) with a muffler. That is, the air flow containing makeup water is the cyclone separator (31).
Flowing into the inlet (31a) of the water, spirally descending in the space (32) formed between the inner cylinder (33), and only the makeup water is supplied from the lower end opening (31b) to the water tank. Reflux into (8). On the other hand, the airflow from which the makeup water has been separated rises in the inner cylinder (33) through the lower end opening (31b) and flows into the inner chamber (41) of the silencer (40) through the discharge port (34). Then, this air flow flows from the inner chamber (41) to the inner pipe (44) and the expansion chamber (43). When flowing from the narrow inner pipe (44) to the wide expansion chamber (43), a high frequency is sucked by the sound deadening principle, and the sound is deadened. The silenced airflow is discharged from the opening (43a) of the expansion chamber (43) through the outlet pipe (45) to the atmosphere.
