Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waste collecting device for collecting waste such as used bedding.

[0002]

2. Description of the Related Art Generally, in small animal breeding facilities for research,
BACKGROUND ART Small animals are housed and housed in plastic cages covered with bedding such as sawdust and wood chips.

Since the above-mentioned bedding is soiled by the excrement of small animals, it is necessary to collect the used soiled bedding from the cage and replace it with a new bedding. Conventionally, the used bedding is collected by reversing the cage and throwing the used bedding into a garbage bag loaded in a large garbage bucket.

However, in such a conventional collecting method, when the cage is turned upside down and the used bedding is thrown into the garbage bag, dust is scattered around and the foul odor of small animals excretes indoors. There was a problem of scattering to.

Therefore, the present applicant has developed a solid waste collecting apparatus as shown in FIG. 4 in order to solve such a problem. In this solid waste collecting device, in the cage 11,
When the suction nozzle 15 at the tip of the flexible hose 13 is inserted, the solid waste material 17 made of used bedding in the cage 11 is sucked, passes through the flexible hose 13 and enters from the inlet 21 of the cyclone separator 19 to the cyclone. It is guided into the expression separator 19.

The solid waste 17 introduced into the cyclone separator 19 is separated into a solid waste 17 having a relatively high specific gravity and dust and air having a low specific gravity by the action of centrifugal force, and the solid waste 17 is caused by its own weight. After being dropped and guided to the discharge port 23, it is collected in the dust bag 27.

On the other hand, the dust and air having a small specific gravity separated by the cyclone separator 19 are sucked by the blower 29, pass through the exhaust port 31 of the cyclone separator 19, and then are guided to the filter 33, where Dust is removed.

The air from which dust has been removed is ejected from the blower 29 into the lower chamber 37 formed by the box body 35, and thereafter, after passing through the exhaust pipe 41 by the air blower 39, passing through the flexible hose 43 and outside the room. Is discharged to.

In the solid waste collecting apparatus described above, the cage 1
The solid waste 17 in 1 is introduced into the cyclone separator 19 together with air and dust in the vicinity of the solid waste 17, and the solid waste 17 having a relatively large specific gravity due to the action of centrifugal force,
Solid waste 1 separated into dust and air with low specific gravity
7 falls by its own weight and is directly collected in the dust bag 27. On the other hand, dust and air having a small specific gravity are sucked by the blower 29 and guided to the filter 33 to remove the dust. It becomes possible to collect the solid waste 17 without doing so.

[0010]

However, in such a solid waste recovery apparatus, since the blower 29 sucks air from the exhaust port 31 of the cyclone separator 19, the exhaust port 23 of the cyclone separator 19 is used. The air in the dust bag 27 communicated with the is sucked toward the cyclone separator 19 side, the inside becomes negative pressure, the dust bag 27 is dented as shown by the chain double-dashed line in the figure, and the sawdust with a relatively small specific gravity is drawn. However, there is a problem that the solid waste 17 made of wood chips or the like does not smoothly flow into the dust bag 27, and it becomes difficult to collect the solid waste 17 into the dust bag 27.

Conventionally, when the dust bag 27 is deflated, the dust bag 27 is removed from the discharge port 23 of the cyclone type separator 19 and air is put into the dust bag 27. A great deal of time was required to attach and detach 27 to and from the outlet.

The present invention has been made in order to solve such a conventional problem, and an object of the present invention is to provide a filth collecting device which can collect filth without squeezing the dust bag.

[0013]

A filth recovery device according to the present invention comprises a cyclone separator having an introduction port, a discharge port and an exhaust port, and an upper end disposed below the discharge port of the cyclone separator. An intermediate recovery container having a container inlet formed at the outlet connected to the discharge port, and an ejector inlet formed at the upper end below the container outlet formed at the lower end of the intermediate recovery container. It has a hermetically-sealed ejector connected to the outflow port, and a dust bag mounting portion formed at the lower end of the hermetically-sealed ejector and connected to the eductor outflow port.

[0014]

In the filth recovery apparatus of the present invention, the filth introduced from the inlet into the cyclone type separator is separated into filth having a relatively large specific gravity and dust and air having a small specific gravity by the action of centrifugal force, The filth falls due to its own weight and is guided to the discharge port, then drops from the discharge port into the intermediate collection container, is temporarily stored in the intermediate collection container, and operates the closed-type discharge device so that the filth inside the intermediate collection container Are moved from the discharger inlet of the closed type discharger toward the discharger outlet, and are collected from the dust bag mounting portion into the dust bag.

That is, since the closed type discharger is arranged at the discharge port of the cyclone type separator via the intermediate recovery container, even if the discharge side of the closed type discharger has a negative pressure, the discharger is discharged. There will be no negative pressure on the outlet side, so
Negative pressure does not occur in the dust bag attached to the dust bag attachment portion connected to the ejector outlet side of the closed type ejector.
