4 Purely mechanical of compression bar valve watering device, the course of work are as follows: material impacts charging plate 4-2, band when entering chute 3
Dynamic connecting rod 4-1 is rotated around 4-3 pivot pin, and then drives multi link 4-4 movement, and then compression bar valve gear 7 is driven to act, sprinkling
Water sprays material dust suppression from water pipe 5 from outflow, through hose 6, sprinkling water pipe 8；When there is no material to enter chute 3, charging plate 4-2
It is not impacted, entire compression bar valve watering device is not triggered, and no spray water is sprayed.
The action process of compression bar valve watering device 4-7 are as follows: when no material enters the impact charging plate 4-2 of chute 3, pivot pin 4-
3 are failure to actuate, as shown in figure 5, not sprinkling water；When material is discharged into chute 3, material impacting is pushed to charging plate 4-2, charging plate
It is moved back towards the right side, under pivot pin 4-3 effect, charging plate connecting rod 4-1 inclines to the left, and at the same time, the side multi link 4-4 pulls compression bar
The connector 4-7-2 of valve, compression bar valve gear 4-7 internal valves are opened, and watering starts, as shown in Figure 6.
In conjunction with Fig. 7, Fig. 8, spray head watering device include water pipe 5, hose 6, rotary shaft 7, sprinkling water pipe 8, sprinkling water pipe mention
Rise device 9, graduated scale 10, fixed frame 13.Water pipe 5 is connected by hose 6 with sprinkling water pipe 8；Water pipe lifting device 9 is sprayed to install
At sprinkling 8 back side of water pipe, graduated scale 10 is configured on chute top canister, for observing sprinkling 9 hoisting depth of water pipe lifting device；
Sprinkling water pipe 8 is connected with rotary shaft 7, and rotary shaft 7 is fixedly mounted on fixed frame 13, and fixed frame 13 is mounted on chute cabinet wall
On；It sprays water pipe lifting device 9 and promotes or reduce certain altitude (referring to graduated scale 10), drive connected sprinkling water pipe
8 rotate around rotary shaft 7.
When material on charging belt machine 1 passes through the electronic scale 2 for being mounted on the belt feeder back side, it is detected a hour flow
V0 after material enters chute 3, impacts charging plate 4-2, triggers the compression bar valve gear 4-7 of compression bar valve watering device 4, spray water warp
Water pipe 5, hose 6, sprinkling water pipe 8 spray, and the material in chute, into blanking belt feeder 12, is mounted on blanking skin after fetching water
11 real-time detection material moisture of infrared moisture meter with 12 top of machine, and transmit into PLC controller.Spray water pipe lifting device 9
It is mounted on sprinkling 8 back side of water pipe, configures graduated scale 10 on chute top canister, is promoted for observing sprinkling water pipe lifting device 9
Highly.
After charging belt machine 1, chute 3, charging plate 4-2 and sprinkling water pipe 8 are constructed, the side of repetition test can be passed through
Formula sums up under 1 difference hour flow V of charging belt machine, into chute 3 after corresponding discharging point and optimal spray angle A
(sprinkling water pipe 8 and horizontal line angle), corresponding best spray angle A is included in control as conventional parameter under different hour flow V
System processed.
The present invention realizes suppression according to the different flow adjustment water-spraying amount of material and spray angle with most economical water consumption
Dirt effect, specific as follows:
1. charging belt machine 1 operates, when the material of conveying passes through the electronic scale 2 for being mounted on the belt feeder back side, it is detected
Hour flow V0 out after material enters chute 3, impacts charging plate 4-2, triggers the compression bar valve gear 4- of compression bar valve watering device 4
7, spray water sprays sprinkling dust suppression through water pipe 5, hose 6, sprinkling water pipe 8；
2. charging belt machine 1 stops, charging plate 4-2 is impacted without logistics, sprinkling water pipe 8 is sprayed without water.
3. charging belt machine 1 operates, when the material of conveying passes through the electronic scale 2 for being mounted on the belt feeder back side, it is detected
Hour flow Vx out, (x 1,2,3, ,) and Vx ≠ V0, indicate that the hour flow for conveying material at this time changes, chute
Interior corresponding discharging point changes, if not adjusting the spray angle A of spray water pipe 8 at this time, sprinkling anti-dust effect will be deteriorated.
By way of repetition test, find out different hour traffic level V1, V2, V3,,, optimal sprinkling angle corresponding to Vn
Spend A1, A2, A3,,, An, by taking hour flow V1 as an example, when the material feed flow of belt feeder 1 is V1, and Vx ≠ V0 is held
When the continuous time is greater than 20 seconds, sprinkling water pipe lifting device 9 promotes or reduces certain altitude (referring to graduated scale 10), drives phase therewith
The sprinkling water pipe 8 of connection is rotated around rotary shaft 7, A1 is adjusted to by the spray angle for spraying water pipe 8, to realize different
Under hour traffic level, corresponding different spray angle realizes economic watering dust suppression.
4. environment is poor in chute 3, when spraying the device fails such as water pipe, if cannot find in time, will lead to
Anhydrous sprinkling, situations such as spray water is not in place, in order to find spray effect at the first time, apparatus of the present invention are further provided with infrared water
Divide instrument 11, when the detection material of electronic scale 2 is small when flow Vx=0, the moisture value Wx that infrared moisture meter 11 detects does not issue alarm
Signal；When charging belt machine 1 starts running, and electronic scale 2 detects material hour flow Vm, when the batch of material reaches infrared moisture meter
When 11 lower section, moisture value Wn is detected, when absolute difference is greater than K% (K according to material level adjustable) between Wn and Wm, and
Duration is greater than L minutes (L is adjusted as needed), shows spray water exception, need to check equipment working state immediately, take phase
The regulating measures answered.By taking Wn is greater than W1 as an example, screw at the spring of compression bar valve side can be manually adjusted, otherwise is tuned up.
The present invention prevents belt conveyor chute the wind-borne dust device from can timely spray control chute interior fugitive dust, and water-spraying amount can
It adjusts, spray angle is reasonable, while can also feed back the moisture for unloading falling material and adjustment, avoids sprinkling that downstream user material is caused to contain
Water is high.Using apparatus of the present invention, hour feed flow 1200t/h, amount of water sprayed 0.5m3/h, 37 degree of spray angle, base in chute
This is without fugitive dust；And using conventional mode of manually fetching water, need post work to reach scene, once post is not at the scene, material occurs
When great fugitive dust, Heavy environmental pollution is caused；Water pipe is automatically turned on using conventional solenoid valve of adding, conveys material hour flow
1200t/h, amount of water sprayed 0.8m3/h, spray angle fix 45 degree, and water spray anti-dust effect is bad, and chute fugitive dust influences environment.
In conclusion using technical solution of the present invention, anti-belt conveyor chute the wind-borne dust device can timely spray control
Chute interior fugitive dust processed, water-spraying amount is adjustable, and spray angle is reasonable；The moisture for unloading falling material and adjustment can be fed back, avoids spraying
It spills and causes downstream user material moisture high；Alternative original spray pattern, it is ensured that most economical water realizes that chute fugitive dust can
It controls, avoid the material excessively hidden danger such as watering or leakage watering, can be widely used to promote in the industries such as metallurgy, power plant.
