Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to compressing and containing dust with an air stream.

Traditionally, inside a factory or workshop (hereinafter referred to as "inside a factory, etc.")
In order to collect dust by suction method,
A commonly adopted method is to suck the dust by means of a suction nozzle, transport it to a collection point by means of a subsequent air flow conducting pipe, and then separate the dust from the conveying air flow. On the other hand, the dust-free and clean air stream is discharged, but in this case the dust stored separately from the conveying air stream is very bulky and cannot be collected for a short time. Since the dust forms large-volume dust particles, dust collection operations must be frequently compressed, often removed and transported to other locations, or a large-volume storage device must be installed in the first place. However, even if compaction work and transportation work are mechanized,
In addition, installing a large-capacity storage device requires a considerable amount of money, so in most cases,
We have relied on human power for compaction and transportation work, but
Since this is a task that people dislike, the labor costs are unexpectedly high, and some kind of countermeasure has been requested for a long time.

The present invention satisfies this need, namely, an upper can _D having a primary filter G on the entire cross section inside the can, which is airtightly connected and can be easily installed and removed, and a bottom surface Ee with air circulation holes. a dust storage can L consisting of a lower can E with a primary filter G at one end;
It opens into the upper can D at a higher position and connects the other end to the blower M via the secondary filter K.
A pipe _P1 for conducting suction air flow with a solenoid valve I attached to the conduit between the secondary filter K and the opening end into the upper can D, and one end connected L between _{the ED} point and the primary filter G. A pipe P 2 for dust conveyance air flow is opened into the upper can D at the position, the other end is connected to the insertion port B, and a solenoid valve C is attached to the conduit outside the can, and one end is connected to the pipe P ₂ .
The pipe line between the opening end of P ₁ into the upper can D and the installation point of the solenoid valve I is joined to the pipe P ₁ , opened into the upper pipe, and the other end is opened to the outside air. A pipe P ₃ for communicating the stored dust and compressed air is equipped with a solenoid valve H in the conduit between the position and the outside air open end, and one end is opened into the lower can E at a position below the bottom surface Ee of the lower can E. Then connect the other end to pipe _P1 in the conduit between solenoid valve I and secondary filter K, and connect solenoid valve J to the conduit between the joint position and the opening end into lower can E. Installed storage dust compressed air flow conduction pipe P ₄ and pipe P ₁ dust storage can L pipe via secondary filter K
Air in P ₂ and pipe P ₄ Dust storage can L Pipe P 3 A blower M for generating a suction air flow that sucks the air in the L pipe P ₃ and discharges it into the outside air, and the rear end Ae of the flexible hose A. When the blower M is inserted, the blower M is automatically started, and when the solenoid valve is removed, the solenoid valves C and I are automatically closed and the solenoid valves H and J are opened. At the same time as the rotation stops, the solenoid valves C and I are automatically opened and the solenoid valves H and J are closed. This is the structure of a dust compression and storage device characterized by comprising a flexible hose A that is inserted into an insertion port B to suck dust.

The structure of the dust compression and storage device according to the present invention (hereinafter referred to as "structure of the device of the present invention") will be described in detail below. FIG. 1 is a simplified side view of an embodiment of the device showing the structure of the device of the present invention. M, a pipe P 2 for conducting the dust transport air flow that transports dust by suction air flow and stores it in the upper can D, a solenoid valve C attached to the pipe P ₂ , and a pipe P ₂ from above the upper can D. When sucking the air inside the dust storage can L, there is a pipe P ₁ for conducting the suction air flow, and a solenoid valve I attached to the pipe P ₁ , and A pipe P _{3 for communicating the stored dust compressed air for introducing outside air (hereinafter referred to as "outside air") into the dust storage can L to compress the stored dust, a solenoid valve H attached to the pipe P 3 ,} and a lower part. A pipe P _{4 for conducting the flow of air compressed with stored dust when suctioning the compressed air from the bottom of the can E, a solenoid valve J attached to the pipe P 4 ,} and a factory etc. It consists of a flexible hose A for sucking up dust, and a plurality of insertion ports B provided in walls, pillars, or floors at various locations in the factory, into which the flexible hoses A are inserted. The dust storage can L consists of an upper can D and a lower can E, both of which are airtightly connected L.
_ED , and the connecting L _ED can be easily installed and removed, and a primary filter G is installed above the upper can D across the entire inside of the can. Blower M automatically starts rotating by inserting the rear end Ae of flexible hose A into any one of the outlets B, and sucks the air in pipe P ₁ , dust storage can L, and pipe P _2. The dust is conveyed by discharging it into the outside air, and the pipe P ₃
By suctioning outside air from the pipe and discharging it into the outside air through the pipe P ₄ , the dust a stored in the dust storage can L is compressed, and the rear end Ae of the flexible hose A is connected to all outlets B. By pulling it out, it continues to rotate for a short period of time, for example, several seconds to 10-odd seconds, without changing its direction of rotation, and then stops. It should be noted that, despite the large amount of friction loss caused by friction with pipes, etc., the blower M has a relatively long distance from the tip of the suction nozzle N attached to the flexible hose A to the blower M. Therefore, one is used that has sufficient capacity to generate a strong air flow. Pipe P ₂ connects one end with L _ED
A pipe P 2 is inserted into the upper can D to open it at a position intermediate between the point and the primary filter G, and the other end is connected to the insertion port _B.
A solenoid valve C is attached to the conduit. pipe
P ₁ has one end opened to communicate with the inside of the upper can D at a position above the installation position of the primary filter G, and the other end is connected to the blower _M. A solenoid valve I is installed in the passageway. Also, the pipe _P1 between the solenoid valve I and the blower M
A secondary filter K is installed across the entire surface of the pipe. Pipe P ₃ has one end connected to the opening end of pipe P ₁ into upper can D and the installation point of solenoid valve I, and joins pipe P ₁ to upper can D.
A solenoid valve H is attached to the pipe line closer to the open air end than the joint position. pipe P ₄
has one end connected to the lower can E at a position below the bottom surface Ee of the lower can E to open,
The other end is connected to a pipe P ₁ at a position intermediate between the solenoid valve I and the secondary filter K, and a pipe P ₄ is located between the joint position and the communication opening position with the lower can E. A solenoid valve J is installed in the pipeline. In addition, the rear end Ae of the flexible hose A is
By pulling out all the plugs from B, the solenoid valves C and I are automatically closed and the solenoid valves H and J are opened, and several seconds to several seconds later, the blower M is stopped, automatically. In addition, solenoid valves C and I are opened, and solenoid valves H and J are closed.
The flexible hose A is a flexible hose that can be bent freely, and when inserted into the outlet B, the length of the suction nozzle N is equal to the length of the flexible hose A with the outlet B as the center. It has the function of being able to suck all the dust a inside a sphere whose radius is the added value. Inlet B is flexible hose A
By inserting the rear end Ae into it, the mouth opens to allow air to pass through, and by removing the rear end Ae from the insertion port B, the mouth closes and allows the air to pass through. This creates an airtight condition that prevents

Next, the operation of the device of the present invention will be explained in detail.

When the solenoid valve I provided on pipe P ₁ and the solenoid valve C provided on pipe P ₂ are open, and the solenoid valve H provided on pipe P ₃ and the solenoid valve J provided on pipe P ₄ are closed, the collection is performed. Due to dust, the rear end Ae of flexible hose A
When the blower M is inserted into any one of the sockets B, the blower M automatically starts rotating, and due to the rotation, the airflow starts to flow in the direction of the arrow _R1 inside the pipe _P1 . The inside of the dust storage can L becomes negative pressure, so the air inside the pipe P ₂ flows in the direction of arrow R ₂ and becomes a suction air flow for dust storage, so it is attached to the tip of the flexible hose A. From the suction nozzle N, dust a such as cotton dust from inside the factory is sucked together with air. As soon as the dust a sucked in with this air enters the dust storage can L, the speed of the conveying air flow decreases.
Most of the dust falls into the dust storage container F in the lower can E of the dust storage can L, and only those with light specific gravity head to the upper part of the dust storage can L and fall into the upper can D.
installed on. By the primary filter G,
It is filtered and becomes a clean air flow _R1 , which blower M
It is then released into the outside air. Next, after the dust a storage work is completed, the rear end Ae of the flexible hose A is
By removing the flexible hoses from all outlets B, the blower M continues to rotate for a short period of time without changing its direction of rotation, and then stops. When the rear end Ae of A is removed from all the insertion ports B, solenoid valves I and C are automatically closed and solenoid valves H and J are opened. _The airflow in the directions of arrows _R1 and _R2 , which had been suctioning airflow for the It becomes an air flow in _{the three} directions of arrow R, and the air flow flows into the dust storage container F.
Bulky and large volume of dust that has fallen into the interior and is stored a
The mass is compressed from above to form a small volume of dust, which flows out from the dust storage container F and the bottom of the lower can E, becomes an air flow indicated by arrow _R4 , and is filtered through the secondary filter K. , filtered and released as a clean air stream. In addition, as mentioned above, dust a
The compressing force is quite strong because the distance between the blower M and the dust storage can L is close, and there is little friction loss with pipes and the like. Furthermore, in this case,
The air flow R ₃ cleans the primary filter G from clogging caused by fine dust caused by the air flow R ₁ .
Furthermore, the bottom surface Ee of the lower can E and the dust storage container F
The bottom surface Ff is formed in a mesh shape that hardly allows dust a to pass therethrough, but allows air flow to pass therethrough, so it does not impede the outflow of the air flow _R4 described above. Also, the upper can D and the lower can E are
Although the L _ED is airtightly connected, the L _ED can be easily removed, so when the dust storage container F in the lower can E becomes full of dust A, the L ED can be easily removed. Take this out and
Although the dust container F can be replaced with a new empty dust container F, when the dust container F becomes full of dust a, a sensor (not shown) can detect this. Now, when blower M, which has continued to rotate for a short period of time, stops, at the same time, solenoid valves H and J automatically close, and solenoid valves I and C
When the door is opened and the next dust collection operation is opened or stopped, the air flow is prepared to flow in the directions of arrows R ₁ and R ₂ to become a suction air flow for collecting dust.

Since the present invention has the above-described configuration, the compacting work of dust lumps, which has conventionally been done manually and is unsanitary and disliked by humans, can be done with a simple operation of simply opening and closing a solenoid valve. , which can be performed automatically, quickly, and easily using a strong compression force, not only contributes to saving labor costs, but also saves energy and is also effective from a hygienic point of view. The structure of the device of the present invention has many useful advantages, such as being able to compress the dust more uniformly and more strongly than by manual labor, making it possible to form dust particles that are easy to transport. It is something.
