CONSTITUTION:The dust collector 1 can be moved by a truck 3, and the dust collection part 4 having a double bag filter is formed on the rear side. The mechanism 31 for spraying an absorbent 33 is furnished behind the dust collection part 4, and the absorbent 33 is sprayed at the lower part of the dust collection part 4 by compressed air through a spraying pipe 39. Dust, exhaust gas, poisonous gases, black smoke, etc., are absrobed by the absorbent 33, and the absorbent is deposited on a bag filter 5 and a unit filter 15. Accordingly, only clean air is discharged to the front side of the truck through the unit filter 15.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a dust collector used at work sites such as tunnel construction and factories.

(Prior Art) Conventionally, since a large amount of dust is generated at underground construction sites such as tunnel construction, or in closed spaces such as factories, dust collectors have been used to collect the dust with a filter cloth or the like.

(Problem to be solved by the invention) However, although this type of dust collector can collect dust, it collects dust from exhaust gas, black smoke, and factory equipment generated from work vehicles used in the space. The problem was that it was not possible to remove toxic gases.

The present invention solves the above problems, and in addition to dust collection,
The present invention aims to provide a dust collector capable of removing poisonous gas and black smoke from exhaust gas.

[Structure of the invention]

(Means for Solving the Problems) In order to achieve the above object, the present invention includes an adsorbent blowing mechanism that blows an adsorbent toward the waist collecting part on the suction side of the dust collecting part provided with the filter material. Established and configured.

(Function) In the present invention, when exhaust gas, toxic gas, and black smoke enter the dust collection unit from the suction side together with dust, the exhaust gas, toxic gas, and black smoke are collected from the suction side by the adsorbent blowing mechanism. It is adsorbed by the adsorbent blown into the filter and adheres to the filter material.

(Example) Fig. 1 is a side view showing an outline of an embodiment of the present invention, Fig. 2 is a plan view seen from above, Fig. 3 is an explanatory diagram of a variable grill,
FIG. 4 is an explanatory plan view of the double back filter. Arrows indicate the flow of intake outside air. The dust collector 1 is movably provided by a truck 3. A dust collection section 4 is formed on the rear side of the track 3, and a double bag filter 5 is provided within this dust collection section 4. Located on the rear side of the dust collecting section 4, suction holes (7a, 7b, 7c) are provided in a corridor manner in three directions, ie, at the rear and left and right sides of the truck 3.

Each suction hole 7 is provided with a movable variable grille 9, and the opening/closing position of each vane 13, 13 of the variable grille 9 can be selected by operating the opening/closing lever 11, as shown in an enlarged view in FIG. It is set up like this. A blower Jttt 5117 is installed between the six unit filters 15 provided at the front of the truck and is driven by the morph 19, and the blower 17 sucks in outside air that has passed through the bag filter 5 from the rear of the trunk and both left and right sides. It is provided so that it is discharged from the upper center through the unit filter 15 to the front of the trunk.

The structure of the double bag filter 5 is shown in the enlarged cross-sectional view of FIG. It forms a unit 1-21 of a double bag filter.

Reference numeral 31 denotes an adsorbent blowing mechanism that is installed at the rear of the trunk 3 and blows the mucus adsorbent 33 into the blood collection section 4. A container 35 is provided for storing a powder adsorbent 33 such as limestone or bentonite. Below this container 35 is a rotary pulp 3 as an opening/closing layer that opens and closes the lower part of the container 35.
7 is provided, from the rotary pulp 37 to the dust collecting section 4.
A blowing vibrator 39 is provided that reaches the lower part of the suction hole 7, that is, the lower part of the suction hole 7, and faces the inside thereof. A compression vibe 41 for sending compressed air is interposed in the middle of the blowing vibe 39, and this compression vibe 41 is connected to a compressor (not shown).

Next, the operation of one embodiment of the present invention configured as described above will be described.

First, the rotary pulp 37 is opened and the adsorbent feeding mechanism 31 is opened.
When the blower 17 is driven at the same time, the blower 1
By suctioning 7, dust, exhaust gas, toxic gas, etc. generated at the work site are sucked into the dust collecting section 4 through the suction hole 7, and the compression vibrator 41 is transferred to the blowing vibrator 39 of the adsorbent feeding mechanism 31. An adsorbent 33 is blown into the dust collection part 4 by the compressed air sent from the air filter, and dust, exhaust gas, toxic gas, black smoke, etc. are adsorbed by the adsorbent 33 and attached to the bag filter 5 and the unit filter 13. Ru. Therefore, dust, exhaust gas, toxic gas, and black smoke are removed, and only clean air is discharged to the front of the truck through the unit filter 15.

As described above, the dust collector l of the present invention uses the double bag filter 5, which has a large S dust effect in combination with the unit filter 13, considering the size of the installation location, so the dust collector can be made small and high. Not only can the performance be improved, but also the exhaust gas, toxic gas, and black smoke along with dust are adsorbed by the adsorbent 33 and attached to the double bag filter 5 and the unit filter 13, making it possible to purify and collect the black smoke. can.

In addition, the intake holes 7 are provided in a corridor manner at the rear of the trunk 3 and in three directions, left and right, and a variable grille 9 is provided in the intake hole 7 so that the opening direction can be freely selected, and the opening degree of the variable grille 9 can be adjusted. As a result, the range of attracting dust can be freely adjusted, so when the dust collector 1 is installed at a corner of a construction site or factory, etc., and must be inhaled only from the right, left, or top. However, it is possible to collect dust reliably.

Note that in FIG. 4, arrows indicate the flow of air during dust collection. Dust removal is performed by generating strong pulsations in the filter cloth using a pulse jet of air of 5 to 7 kgZd to remove dust, and the dust removal is automatically operated by adjusting the filter cloth.

The dust that has been brushed off is collected by, for example, a screw conveyor.

Further, this falling effect of the dust D can also be achieved by obtaining engine driving force from the vehicle 3 and applying slight vibrations to the bag filter.

It should be noted that the present invention is not limited to the above-described embodiments, but includes other embodiments other than the above-mentioned embodiments. It can also be carried out by three persons.

〔Effect of the invention〕

As is clear from the above description, when exhaust gas, toxic gas, and black smoke enter the dust collecting section from the suction side together with dust, the exhaust gas, toxic gas, and black smoke are removed by an adsorbent blowing mechanism. Since the particles are adsorbed by the adsorbent blown into the dust collecting section from the intake side and attached to the filtering material, it is possible to purify exhaust gases and toxic gases and collect black smoke in addition to collecting fine particles.
