Abstract
The invention discloses an automatic following watering dust suppression device for coal operation of a portal crane. A plurality of dust suppression nozzles are arranged on a gantry platform, a pillar platform, a pull rod and the like of the portal crane to ensure a 360-degree dust suppression range; meanwhile, atomizing dust suppression nozzles are arranged on an elephant nose beam forehead, are controlled by a controller and electromagnetic valves to suppress flying dust in the running process of a grab bucket from top to bottom in a water mist mode to realize stereo dust suppression. The automatic following watering dust suppression device has a function of automatically following a pollution source. Corresponding water jetting equipment is started in time under the control of a water jetting controller according to state information such as a rotation angle of the portal crane, the opening and closing state of the grab bucket and the like, and the pollution source is under control constantly. Meanwhile, equipment that pollutants are absent in the working range can automatically stop, and the utilization efficiency of water resources is improved.
Description
Technical field:
The invention belongs to ports handling machine dust suppression technology, particularly a kind of transfer crane coal operation dust-arrest device of sprinkling water automatically.
Background technology:
But having in harbour handling work comparatively widely because of the good handling goods kind of its commonality is many, uses transfer crane.But, when using transfer crane to carry out bulk goods operation such as coal, often be accompanied by comparatively serious dust pollution question.At present, mostly harbour bulk handling harbour is in the stockyard, the quay surface is provided with spray gun, suppresses airborne dust by the goods buttress is sprayed water.Though this mode can play certain anti-dust effect, also come with some shortcomings simultaneously:
1, dust suppression scope is little, can't realize three-dimensional, all standing dust suppression.Ground dust suppression spray gun is subject to objective factor influences such as position, hydraulic pressure, and the airborne dust that the opposite house machine takes, puts in material and the door machine grab bucket operational process suppresses scarce capacity.
2, water resource utilization efficiency is not high.Because ground watering dusting equipment controllable function is single relatively, can not be according to the dust suppression operation of sprinkling water as required of equipment availability situation, caused that anti-dust effect is undesirable, water resource utilization efficiency is low.
Need to invent a kind of degree of automation height for this reason, anti-dust effect is good, water utilization rate is high, and up-to-date technology---the watering dust-arrest device is followed in the operation of transfer crane coal automatically, to overcome the above problems.
Summary of the invention:
Problem to be solved by this invention is: provide the operation of a kind of transfer crane coal to follow the watering dust-arrest device automatically, solve the transfer crane operation and can't realize three-dimensional, all standing dust suppression, the existing simultaneously problem that anti-dust effect is undesirable, water resource utilization efficiency is low.
Technical scheme of the present invention:
The watering dust-arrest device is followed in the operation of a kind of transfer crane coal automatically, it is characterized in that: at transfer crane lower framework platform, rotary column platform with the spray water device is set above the pull bar, on the grab bucket straight-arm trunk beam forehead of the grab bucket vertical direction of transfer crane, the spray water device is set.
Described each spray water device connects water supply pipe, on the water supply pipe of each spray water device control electromagnetic valve is arranged, and control electromagnetic valve connects controller respectively, and the controller connection is arranged on the sensor around the transfer crane.
Effect of the present invention is:
The operation of transfer crane coal is followed the watering dust-arrest device automatically and is provided terms of settlement for the airborne dust inhibition ability that promotes in the transfer crane coal operation process.By the sprinkler that is provided with at the transfer crane diverse location and sprinkler controller according to of the control of door machine mode of operation to each sprinkler equipment, realize the automatic tracking of dust suppression, reached the purpose that promotes anti-dust effect, reduced water resources consumption for source of pollution.
Description of drawings
Fig. 1 is that watering dust-arrest device scheme drawing is followed in the operation of transfer crane coal automatically
Fig. 2 is that watering dust-arrest device water route control chart is followed in the operation of transfer crane coal automatically
The specific embodiment:
The watering dust-arrest device is followed in a kind of transfer crane coal operation as shown in Figure 1 automatically, at transfer crane lower framework platform 1, rotary column platform 2 with the spray water device is set above the pull bar 3, on the grab bucket straight-arm trunk beam forehead of the grab bucket vertical direction of transfer crane, the spray water device is set.
The watering dust-arrest device is followed in the coal operation of assembling on the transfer crane automatically: 1, at transfer crane door frame platform, rotary column platform, pull bar etc. some spray water device dust suppression shower nozzles are set, see Fig. 1, guarantee 360 ° of all standings of dust suppression scope, at trunk beam forehead atomizing dust suppression shower nozzle is set simultaneously, from top to bottom the airborne dust in the grab bucket operational process is suppressed with water smoke, realize three-dimensional dust suppression.
Each spray water device connects water supply pipe 4 as shown in Figure 2, and control electromagnetic valve 6 is arranged on the water supply pipe of each spray water device 5, and control electromagnetic valve connects controller 7 respectively, and the controller connection is arranged on the sensor 8 around the transfer crane.Sensor is the dust dust sensor.
Possess source of pollution and follow function automatically.Sprinkler according to status informations such as the transfer crane anglec of rotation, grab bucket open and-shut modes, is opened corresponding sprinkler in good time under the control of water spray controller, guarantee that source of pollution are in the Be Controlled state constantly, promotes the utilization ratio of water resource.
This technology is applied to harbour handling with on the transfer crane.By high pressure water is introduced transfer crane, automatically follow source of pollution sprinkle water dedusting operation according to the sensor feedback information decision gate machine mode of operation that is arranged on each mechanism of machine and by the PLC control setting at the electromagnetic valve of diverse location shower nozzle by the dust suppression controller, thereby realize comprehensive, three-dimensional watering dust suppression operation.
Claims (2)
1. the watering dust-arrest device is followed in transfer crane coal operation automatically, it is characterized in that: at transfer crane lower framework platform, rotary column platform with the spray water device is set above the pull bar, on the grab bucket straight-arm trunk beam forehead of the grab bucket vertical direction of transfer crane, the spray water device is set.
2. the watering dust-arrest device is followed in transfer crane coal according to claim 1 operation automatically, it is characterized in that: described each spray water device connects water supply pipe, on the water supply pipe of each spray water device control electromagnetic valve is arranged, control electromagnetic valve connects controller respectively, and the controller connection is arranged on the sensor around the transfer crane.
