Description

[Detailed explanation of the invention] Due to the growing awareness of occupational health, dust generated in paddy drying and preparation facilities (mainly broken mushrooms)
The dust generated in these facilities not only deteriorates the working environment, but also poses a major problem to the living environment around the facilities.

Although dust prevention measures in paddy drying and preparation facilities are an urgent and important issue, the current situation is that no perfect dust prevention device has been developed (devised).

The present invention relates to a dust collection device for a rice drying and preparation facility that exhibits an excellent dust-proofing effect, and its configuration is detailed as follows with reference to the accompanying drawings.

A dust screening screen tube 3 is installed between the front and rear walls 2a near the top of a box-shaped dust removal case 2 that is open at the bottom and has small ventilation holes 1 scattered at the bottom. An introduction tube 4 is connected in series, and a dust discharge tube 6 from which a dust collection mesh bag 5 (approximately 25 mesh bags) is suspended is connected to the other end.

This dust sorting screen tube 3 is square in shape, and the left and right parts except for the bottom part and the ceiling part are formed into a mesh (approximately 10 mesh).

The dust removal case 2 shown in the drawings is formed of a sheet so as to be foldable.

A case is shown in which the dust introduction tube 4 is also formed integrally with the dust removal case 2 from a sheet.

The lower part of this dust removal case 2 is stored in the dust collection water tank 7, and the top part of this dust removal case 2 is fixed to the top part 8a of the pillar 8 provided on the left and right sides of the dust collection water tank 7, so that the dust removal case 2 is erected. The state is maintained.

A shower device 9 that sprays (mists) water horizontally around the surrounding area is installed at the center of the dust removal case 2 below the dust sorting screen tube 3, and the end of the water pipe 10 of the shower device 9 is connected to the dust collection water tank 7. A pump 11 is provided in the middle or at the end of this water pipe 10.

In the figure, reference numeral 12 denotes a water droplet scattering prevention mesh plate having guide portions 13 provided in the lower portions of the left and right walls 2a of the dust removal case 2. (It is preferable to form a sheet integrally with the dust removal case 2 like the dust removal case 2.) Since the present invention is configured as described above, the dust-containing air introduced from the dust introduction tube 4 into the dust screening screen tube 3 The dust directly passes through the dust sorting mesh tube 3 and is collected from the dust discharge tube 6 into the dust collection net bag 5;
Due to wind pressure, some particles are blown out from the mesh of the dust screening tube 3 into the dust removal case 2.

What is collected in the dust collection mesh bag 5 is coarse dust, and what is blown out from the dust sorting mesh tube 3 is fine dust.

Clean air is discharged from this dust collection net bag 5,
When the fine dust blown out from the dust sorting screen tube 3 falls inside the dust removal case 2, the shower water from the shower device 9 hits the fine dust, and the fine dust, which has become heavy due to the shower water, falls into the dust collection tank 7. It will be collected.

The air inside the dust removal case 2 is exhausted to the outside through the ventilation hole 1.

In this way, the present invention separates coarse dust and fine dust into two types.
Since it is collected separately, a reliable and highly efficient dust collection device can be expected, and the fine dust is also sprayed with shower water as it falls, absorbing water and making the fine dust heavier and forced into the dust collection water tank 7. Since it is dropped, even small fine dust can be reliably collected.

The fine dust collected in the dust collection water tank 7 can be easily thrown away by removing the dust removal case 2.

As described above, the present invention provides a dust collector with high collection efficiency, has a simple structure, reduces the cost of the product, and is easy to handle. It is effective.
