Background technology
A large amount of dust can be generated in the blasting procedure of constructing tunnel and whitewashing process, seriously affects construction environment.At present
Mostly using measures such as spray sprinkler depositing dust method, ventilation depositing dust methods, wherein, spray sprinkler depositing dust method is only applicable to blasting procedure,
Pair with dust suppression, prevent it is secondary be diffused with preferable effect, but watering and lowering dust is very low to the dust efficiency of dust collection in air, spraying
Worker's operation can be influenced, spray anchor operation cannot use, and labour hygiene standard is extremely difficult to the dedusting of spray sprinkler.Ventilation
Dedusting is to dilute dust concentration with air quantity, and the precondition for reaching labour hygiene standard is that wind speed will reach 0.2m/min, but
It is if tunnel tunnel face is fallen into the range of 3~5m, can not meets for current ventilation condition, therefore its dust removal by ventilation
Effect be halfway.
It can be seen that there are the problem of the scope of application is small, dust removing effects are poor for existing ventilation dust falling device.
Utility model content
Technical problem to be solved in the utility model is that the scope of application present in existing ventilation dust falling device is small, removes
The problem of dirt effect is poor.
In order to solve the above-mentioned technical problem, technical solution is to provide a kind of removing for bored tunnel used by the utility model
Dirt equipment, including：
Rose Box, internal is cavity, and several filter bags are equipped in the cavity, and the side wall of the Rose Box is equipped with connection
The suction inlet of the cavity, the top of the Rose Box are equipped with the air exhausting device for connecting the cavity, and the Rose Box is equipped with
For dust to be made to be detached from the dust-extraction unit of the filter bag；
Collect ash cellar, be arranged on the bottom of the Rose Box, the top of the collection ash cellar is equipped with the opening for connecting the cavity.
In said program, the dust-extraction unit includes being arranged on the electric motor of shaker at the top of the Rose Box.
In said program, the air exhausting device includes exhaust duct, and the exhaust duct is arranged on the top of the Rose Box,
And the cavity is connected, fan and muffler are equipped in the exhaust duct.
In said program, the end of the exhaust duct is equipped with the nozzle of the wind speed and direction for changing discharge wind.
The utility model, dust enters cavity by suction inlet, and adsorbs on filter bag, and fall under the action of cleaner
It falling in collection ash cellar, filter bag is fully utilized, and has higher efficiency of dust collection, and the efficiency of dust collection of Rose Box reaches more than 99%,
Meet labour hygiene standard.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings of the specification.
As shown in Figure 1, the utility model provides a kind of cleaner of bored tunnel, including Rose Box 10, collection ash cellar
20, collection ash cellar 20 is arranged on the bottom of Rose Box 10, for accepting the dust that Rose Box 10 filters out.The inside of Rose Box 10 is
Cavity, the cavity is interior to be equipped with several filter bags 11, and the side wall of Rose Box 10 is equipped with the suction inlet 12 of connection cavity, Rose Box 10
Top is equipped with the air exhausting device of connection cavity, and Rose Box 10 is equipped with the dust-extraction unit for dust to be made to be detached from filter bag 11.
Dust-extraction unit includes the electric motor of shaker 18 for being arranged on 10 top of Rose Box, and dust is in the shock effect of electric motor of shaker 18
Lower disengaging filter bag 11 is simultaneously fallen in collection ash cellar 20, and 18 connection of electric motor of shaker has control module, control module connection
There is switch board 13, the initiation culture of electric motor of shaker 18, the duration of vibrations can be set by switch board, it can be flexible according to actual condition
Adjustment, the top of collection ash cellar 20, which is equipped with, to be open, the cavity in the open communication Rose Box 10, and the dust adsorbed on filter bag 11 is shaking
It beats under the action of motor 18, is fallen into collection ash cellar 20 by the opening.
Air exhausting device includes exhaust duct 14, and exhaust duct 14 is arranged on the top of Rose Box 10, and connects the sky of Rose Box 10
Chamber, exhaust duct 14 is interior to be equipped with fan 15 and muffler 16, and fan 15 makes to form negative pressure in cavity, and dust is made constantly to pass through suction inlet
12 are inhaled into.The end of exhaust duct 14 is equipped with the nozzle 17 of the wind speed and direction for changing discharge wind, the air outlet of nozzle 17
The shapes such as round, flat can be set, wind speed and direction, good dedusting effect can be adjusted according to actual needs.
The design performance of this cleaner is as shown in table 1, and filtration velocity reaches 5m/min, compared to general bag-type dusting mistake
Wind speed 1m/min is filtered, with higher wind speed, simultaneously also there is the filter area of bigger, smaller body is obtained with this
Product expands the use scope of this cleaner.
During bored tunnel is constructed, dust of different nature, the collection that can be such as formed in the lower section of hopper can be formed
