Abstract
The utility model discloses a dust removal system of a grab bucket discharge, which comprises a grab bucket and a discharge bin arranged below the grab bucket, an opening of the discharge bin is provided with a dust collector, the dust removal system is characterized that a dustproof cover is further arranged on the grab bucket and can be used for covering the opening of the discharge bin, a damper is further arranged on the dustproof cover, the dust collector comprises a frustum-shaped dust collection box, and the frustum-shaped dust collection box is connected with a dust collection pipeline via a single-point dust catcher. The dust removal system has a simple and reasonable structure and is convenient to install and easy to implement; air volume of the dust catcher can be reduced, and energy consumption is reduced; dust collection efficiency of a negative-pressure dust removal system can be improved; material is recovered; more importantly, unorganized discharge of dust is reduced, and low-carbon and environment-friendly economic indicator proposed by China is met.
Description
Technical field
The utility model relates to prevention and control of air pollution field, the system that particularly a kind of dust that grab bucket is produced during discharging carries out dedusting.
Background technology
Flourish along with harbour bulk shipping industry, the demand of grab bucket ship unloader is also in continuous increase.In addition, in industries such as smelting iron and steel, thermal electric generation, minings, a lot of solid accumulations are in stock ground.The material handling in port and pier and stock ground is all often to be picked up and put in discharging feed bin by grab bucket, transfers on automobile or other transportation meanss.This process inevitably can produce the phenomenon that dust escapes in a large number, causes goods damage and aerial contamination.Along with production level and scientific and technical development, the aerial contamination how dust being brought is reduced to minimum level, has become the important indicator of weighing loading-unload machine equipment environmental protection and energy saving level.The handling of the bulk material such as traditional ore, coal adopts watering dedustings, but some material such as cement, phosphate and grain etc. do not allow contact with water, therefore must employing dry dust removal mode, and the method for depression dust-removing solves dust pollution question.In existing depression dust-removing system, discharging feed bin is all generally unlimited, and above feed bin, periphery is provided with dust collect plant, and the collection efficiency of this class dust collection manner impact dust is limited, still has a large amount of dust uncontrollable discharges.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of dust pelletizing system of the discharging of grabbing bucket is provided, and this dust pelletizing system can improve the collection efficiency of existing negative blast dust pelletizing system, reduces the uncontrollable discharge of dust.
Technical solution adopted in the utility model is as follows:
A grab bucket discharging dust pelletizing system, comprises grab bucket and the discharging feed bin that is positioned at grab bucket below, at described discharging feed bin Hatch Opening, is provided with dust eliminating equipment, it is characterized in that: in described grab bucket, be also provided with a cover of dust that can cover described discharging feed bin Hatch Opening.
On described cover of dust, be also provided with damper.When the cover of dust in grab bucket approaches and overlaps with terrace with edge shape suction box, damper plays the effect of vibration damping and sealing.
Described dust eliminating equipment comprises a terrace with edge shape suction box, and described terrace with edge shape suction box is connected by dust sucting pipeline with a single-point dust exhaustor.
Described terrace with edge shape suction box inside is wind channel, and the inwall surrounding of terrace with edge shape suction box offers suction port, and described suction port is connected with wind channel, and described wind channel is connected with dust sucting pipeline.
Described terrace with edge shape suction box inside is wind channel, and the inwall surrounding of terrace with edge shape suction box offers suction port, and described suction port is connected with wind channel, and described wind channel is connected with dust sucting pipeline.
The material of described cover of dust can be metal sheet, rubber plate or plastic flagstone.
Described discharging feed bin is installed on a bearing.
Described single-point dust exhaustor bottom is provided with automatic discharging valve.
Principle of work of the present utility model is for being undertaken in the process of discharging by discharging hopper when grab bucket, when grab bucket is above discharging hopper, terrace with edge shape suction box is side-suction type gas skirt, along with the drop between grab bucket and discharging hopper more and more hour, especially when grab bucket overlaps with the terrace with edge shape suction box of discharging hopper top, during grab bucket blowing, now Dust Capacity reaches maximum, cover of dust and the terrace with edge shape suction box of grab bucket top have formed an airtight gas skirt, and collection efficiency moment of dust is reached to maximum.
Compared with the prior art the utility model has the following advantages:
The utility model is simple and reasonable, easy for installation, be easy to realize; Can reduce the air quantity of dust exhaustor, reduce energy consumption; Can improve the collection efficiency of existing depression dust-removing system to dust, not only reclaim material, the more important thing is the uncontrollable discharge amount that has reduced dust, meet the economy index of the low-carbon environment-friendly of country's proposition.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the B-B cutaway view of Fig. 2;
Fig. 4 is the structural representation of the grab bucket of cover of dust;
Wherein 1 is terrace with edge shape suction box, and 2 is bearing, and 3 is discharging feed bin, and 4 is dust sucting pipeline, and 5 is automatic discharging valve, and 6 is single-point dust exhaustor, and 7 is damper, and 8 is cover of dust, and 9 is grab bucket, and 10 is suction port, and 11 is wind channel.
The specific embodiment
Referring to Fig. 1 ~ Fig. 4, the dust pelletizing system of grab bucket discharging of the present utility model, it comprises with the grab bucket 9 of cover of dust 8 and with the discharging feed bin 3 of dust eliminating equipment and forming.
Grab bucket with cover of dust comprises that grab bucket 9, the grab bucket cover of dust 8 of 9 tops, the damper of cover of dust 8 belows 7 form.Discharging feed bin 3 is fixedly installed on bearing 2.The top of discharging feed bin is fixedly installed terrace with edge shape suction box 1.Terrace with edge shape suction box 1 is connected by dust sucting pipeline 4 with single-point dust exhaustor 6.Single-point dust exhaustor 6 bottoms are provided with automatic discharging valve 5.
The damper 7 that cover of dust lower end is provided with can effectively prevent that the dust in discharging hopper from escaping.
Terrace with edge shape suction box 1 inside is wind channel 11, and the inwall surrounding of terrace with edge shape suction box 1 offers suction port 10, and described suction port is connected with wind channel 11, and described wind channel 11 is connected with dust sucting pipeline 4.
The dust of terrace with edge shape suction box 1 enters automatic discharging valve 5 and discharges after single-point dust exhaustor 6.
