Abstract
The utility model relates to a self-sealing switching type de-dusting device for a bunker, and is suitable for movably de-dusting the bunker such as a blast furnace bunker and a batching chamber bunker. The device is arranged on a movable discharging dolly 7 and each bunker. A bunker discharging port 8 on the discharging dolly 7 for movably discharging is covered with a sealing belt 1. The sealing belt (1) winds around a chute 10 on the discharging dolly 7 to be n-shaped. A negative pressure cover 2 is disposed on the side face of each bunker. The negative pressure cover is connected with a collecting pipe 6 via a connecting cover 3 and a connecting pipe 5. The collecting pipe 6 is arranged on the outer wall of one side of the bunker. The self-sealing switching type de-dusting device for the bunker replaces switching of a motorized valve door on the bunker, thereby effectively minimizing dust flowing, reducing energy consumption for device operation and ensuring reliable operation for a system.
Description
Technical field
The utility model belongs to the ventilating dust-removing technology field, be specifically related to the control device of dirt source point in the storehouse, be particularly related to a kind of in the storehouse of movable sealing suitching type dust arrester, this device mainly is applicable to mobile dedusting on the storehouse, as dedusting on dedusting on the blast furnace hopper storehouse, the proportioning room storehouse etc.
Background technology
Ventilating and purifying air system on the tradition storehouse; great majority all are at the ore deposit groove edge dust shield to be set respectively; an electrically operated valve is set behind each dust shield; electrically operated valve and groove loading and unloading material car interlocking; when the dummy car discharging, the valve of this groove is opened automatically, takes the dust-contained airflow of this groove away; prevent that dust from overflowing from discharge port, healthy with protection environment and field worker.But the dust shield with the dummy car interlocking of every groove setting switches electrically operated valve and often breaks down, and can not normally open and close.When the valve that should normally close can not be closed, during exhausting, the air quantity that should concentrate on controlled hopper dust shield is assigned to the dust shield of a plurality of non-material controlling grooves to a plurality of valves simultaneously, and the air quantity of controlled hopper reduces relatively, and system is the exhausting dust suppression normally.Hopper is poorly sealed in addition, and the air leak rate of air curtain height requires air quantity bigger, and general conventional air quantity is difficult to the capture clean-up effect that reaches desirable to dust.
Summary of the invention
The purpose of this utility model is to overcome in traditional storehouse exhausting system to switch because of electrically operated valve is frequent and cause the normally shortcoming of exhausting dust suppression of system, and the cancellation dust shield is with the mode that electrically operated valve switches, provide a kind of in the storehouse of movable sealing switching dust arrester.
The utility model purpose realizes by following technical solution: a kind of in movable sealing suitching type storehouse dust arrester, this device is installed on dump car and each storehouse, cover the sealing belt at the Cang Shangxieliaokou of dump car mobile discharge, the sealing belt is walked around the chute on the dump car, be " several " font, the sealing belt is fixed on the dump car side by guide wheel and support.Negative pressure cover is installed in side on each storehouse, and negative pressure cover is connected with concetrated pipe with tube connector by connecting cover, and concetrated pipe is installed on the exterior wall of a side in the storehouse, between connection cover and tube connector manual volume damper is set.
Operation principle: sealing belt coiled " several " font that covers discharge port is installed on the mobile discharge dolly, like this by chute, chute mouth and feed bin are all sealed by belt, chute mouth on the dump car moves to that storehouse, and that storehouse just is opened, and just has air-flow to enter.Sealing belt 1 has been realized the opening and closing of feed bin, the actual effect of having played original electrically operated valve sealing switching.
According to actual conditions several negative pressure covers can be set on each storehouse, negative pressure cover communicates with each storehouse, when having the dump car that seals belt and move to the discharging of any one storehouse, this storehouse is communicated with the negative pressure cover that install in this storehouse, other storehouse seals, and the negative pressure cover of installing on other storehouse is also closed simultaneously.
Manually the effect of volume damper is system's adjustment effect when operation, and manual volume damper is regulated the resistance of each negative pressure cover before system's operation, makes it to reach the balance unanimity.When adjusting finishes, manually volume damper 4 apertures remain unchanged.
Tube connector is connected to negative pressure cover, connection cover, manual volume damper on the concetrated pipe, and concetrated pipe is a pipeline that caliber is constant, is the passage of dusty gas in the storehouse.
Because the sealing belt has played the effect that feed bin is opened, closed, the mobile discharge dolly is when the discharging of some storehouses, this position in storehouse is in open mode, negative pressure cover also is in open mode on the storehouse corresponding with it, because other storehouse is a closed state, do not have air-flow to enter, the negative pressure cover on other storehouse is in closed condition at this moment.Negative pressure cover and synergy by sealing belt on the storehouse of mobile discharge dolly, realized exhausting storehouse the in from the movable sealing handoff functionality, successfully solved the difficult problem of electrically operated valve switching.
Negative pressure cover cover one's intention as revealed in what one says speed and dimensional parameters are determined: quantity and air quantity that each storehouse negative pressure cover is set according to the size in storehouse.Cover one's intention as revealed in what one says speed can not be too high, prevents to take out material; Because the belt good sealing effect, less air quantity just can satisfy the requirement of mobile dedusting on the large-scale storehouse, has reduced the cleaner operation energy consumption simultaneously.
The important technological parameters of dust arrester in this storehouse:
1, exhausting amount 25000-35000m
3/ h
2, airborne dust capture rate 〉=98%
3, air leak rate of air curtain≤5%
4, post dust concentration≤8mg/Nm
3
The beneficial effects of the utility model are:
1. the dust arrester in movable sealing suitching type storehouse that the utility model proposes has replaced the switching of electrically operated valve on the storehouse, for the reliability service of system provides strong assurance.
2. the dust arrester in movable sealing suitching type storehouse that the utility model proposes by the sealing of the belt on the mobile discharge dolly, can effectively reduce the excessive of dust, reduces the system dust removing total blast volume.Simultaneously, because the mobile discharge dolly moves, the sealing belt has played automatically in the storehouse and has sealed the effect of switching; According to the principle of air-flow through-flow, there is air-flow to enter, just there is air-flow to extract out, also played an effect that electrically operated valve switches from movable sealing simultaneously for negative pressure cover.
3, the dust arrester in movable sealing suitching type storehouse that the utility model proposes, because concetrated pipe is the constant pipeline of diameter, SR reduces greatly, the air-flow operation is smooth and easy, has reduced the cleaner operation energy consumption.
4. the dust arrester in movable sealing suitching type storehouse that the utility model proposes is simple in structure, and steel consumption is little, and it is very convenient to make.
