Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A dust removal system for a four-arm bolting machine according to an embodiment of the present invention will be described with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of a dust removal system for a four-arm bolting machine according to an embodiment of the present application. As shown in fig. 1 and 2, a dust removing system 100 for a four-arm bolting machine according to an embodiment of the present application includes: the dust removal filter comprises a box body 10, an air inlet pipe 20, a dust removal filter element 30 and an air outlet 40.
The box body 10 is connected with a silencer of the four-arm anchor rod machine through an air inlet pipe 20 so as to send the target gas subjected to silencing treatment into the box body 10, wherein the box body 10 contains adsorption liquid so as to perform primary dedusting on the target gas.
The dust removal filter element 30 is arranged in the box body 10, the position of the dust removal filter element 30 is higher than the liquid surface in the box body 10, and the dust removal filter element 30 is used for carrying out secondary dust removal on the target gas.
The exhaust port 40 is disposed on the case 10, the position of the exhaust port 40 is higher than the dust removal filter element, and the exhaust port 40 is used for discharging the target gas subjected to the two-stage dust removal processing.
It should be noted that, the former dust pelletizing system of four arm roof bolter mainly comprises drill box, swirler, settling chamber, filter core, fan, muffler and tuber pipe etc. and its specific work flow is: dust → drill box → cyclone → dust box (settling chamber → filter core) → blower → muffler. However, because the dust removal effect of the former dust pelletizing system of four-arm anchor rod machine is relatively poor, this application further provides a dust pelletizing system for four-arm anchor rod machine, links to each other with the silencer of four-arm anchor rod machine through intake pipe 20, promptly, takes in the gas after the former dust pelletizing system of four-arm anchor rod machine handles and carries out the secondary dust removal in the dust pelletizing system that this application provided.
Specifically, the secondary dust removal of this application carries out the two-stage dust removal to target gas, and wherein, the first grade is in adsorbing the hydrophilic substance in the target gas in the liquid through adsorption liquid to reduce the water-soluble harmful substance in the target gas, and the second grade filters target gas for dust removal filter core, and finally, the target gas after first grade dust removal and second grade dust removal passes through the gas vent and discharges outside the box.
The adsorption liquid is a liquid capable of adsorbing the hydrophilic harmful substance in the target gas, and may be a mixed liquid or at least water, and may be specifically formulated according to the components of the hydrophilic harmful substance in the target gas. It should be understood that, due to the liquid adsorption force, at least large particle dust in the target gas can be adsorbed, and then the fine particle dust in the target gas is purified and absorbed by the dust removal filter element 30.
Optionally, the air outlet of the air inlet pipe 20 may be disposed below the surface of the liquid to be adsorbed, so that the target gas can be directly subjected to primary dust removal by the adsorbed liquid after being discharged; alternatively, the air outlet of the air inlet pipe 20 is disposed at a predetermined distance from the surface of the liquid to which the liquid is adsorbed, so that the target gas is settled stably by itself after being discharged into the container 10, so that the hydrophilic harmful substances can be adsorbed by the adsorbed liquid at the bottom of the container 10.
Optionally, the precision of the dust removal filter element 30 is higher than that of the three-stage dust remover, so as to improve the dust removal effect on fine dust in the target gas.
Further, the dust removing system 100 for the four-arm bolting machine further comprises: a first baffle 50.
The first baffle 50 is disposed at the bottom of the dust-removing filter element 30, the first baffle 50 is provided with a hole, and the dust-removing filter element 30 is disposed on the hole.
Specifically, the first baffle 50 is used for isolating the target gas which is not subjected to the secondary dust removal in the lower portion of the box 10, and the dust removal filter element 30 is disposed on the hole of the first baffle 50, so that the target gas subjected to the primary dust removal can only enter the dust removal filter element 30 through the hole of the first baffle 50 to forcibly perform the secondary dust removal. It should be understood that the gas after the secondary dust removal by the dust removal filter element 30 is located above the first baffle 50 before being discharged out of the tank through the gas outlet 40, i.e., the first baffle 50 serves to isolate the target gas after the secondary dust removal from the target gas without the secondary dust removal.
Optionally, the dust removing system 100 for the four-arm bolting machine further includes: and a second shutter 60.
Wherein, the second baffle 60 is arranged between the surface of the liquid for adsorbing the liquid and the dust removing filter element 30, and the second baffle 60 is used for preventing the adsorbed liquid from splashing.
It should be noted that, the target gas generally has a relatively large pressure when being discharged through the silencer of the four-arm bolting machine, and the target gas having the pressure impacts the liquid surface of the absorption liquid to easily cause the absorption liquid to splash, so as to prevent the absorption liquid from splashing into the dust removal filter element 30 to affect the dust removal effect of the dust removal filter element 30.
Further, the second baffle 60 is a louver structure, so that the target gas after the primary dust removal enters the dust removal filter element 30 through the gap of the second baffle 60.
Further, the dust removing system 100 for the four-arm bolting machine further comprises: a backwash device 70.
Wherein the back washing unit 70 is provided at the bottom of the tank 10.
It should be noted that the back washing unit 70 may be disposed at the bottom of the tank 10 to impact the deposited dust at the bottom of the tank 10.
Further, the dust removing system 100 for the four-arm bolting machine further includes: and a dust sensor.
The dust sensor is connected to the anti-impact device 70 to control the back-flushing device 70 to open when the dust sensor detects that the dust reaches a predetermined concentration, so as to impact the dust at the bottom of the box 10.
It should be appreciated that the dust extraction system 100 for a four-arm bolter, further includes: a water inlet line 80 and a water discharge line 90.
Wherein a water inlet line 80 and a water discharge line 90 are provided at the bottom of the housing 10 to supply and discharge an adsorption liquid into the housing 10.
Specifically, before the four-arm bolting machine starts to be used, the water inlet pipeline 80 can be used for providing adsorption liquid into the box body 10, and when the anti-impact device is started for a preset number of times or the four-arm bolting machine finishes working, the liquid adsorbed with large particle dust can be discharged by the drainage pipeline 90.
Alternatively, to facilitate cleaning of the dust extraction system, the housing 10 may have a separate lid that is attached to the housing side walls by hinges. The casing 10 may have a transparent structure in order to detect the internal state of the casing 10.
To sum up, this application sets up wet, dry two-stage dust pelletizing system through the muffler export at the four-arm roofbolter, adsorbs the large granule dust through the absorption liquid in the box and dissolves, filters through this dust removal filter core, filters slight dust, finally gets into the working face with the gas discharge after purifying and plays to make the dust reduce to the concentration harmless to the human body.
Actually measured, during the working period of bolting, the dust concentration discharged by the original four-arm bolting machine after being dedusted by the self-configured three-stage dedusting device is 40mg/m3 of total dust and 17mg/m3 of respiratory dust. After the dust removal system provided by the application is arranged on the original four-arm bolting machine, the concentration of the discharged dust is 3.0mg/m3 of the total dust and 2.0mg/m3 of the respiratory dust, and the dust discharge amount is greatly reduced.
Moreover, the dust pelletizing system that this application provided has advantages such as simple structure, economical and practical, simple to operate. The dust removal box body is placed on two sides of the tail of the four-arm anchor rod machine, so that the occupied space is small, and pedestrians and use are not affected.
