Abstract
The utility model discloses an ash discharging and dust removing device which comprises an inner sleeve pipe, a dust removing cover, a material distributor, negative pressure pipes and a negative pressure dust removing system, wherein the upper end of the inner sleeve pipe is capable of being connected with an ash hopper, the dust removing cover is arranged below the lower end of the inner sleeve pipe, the material distributor is connected with the bottom of the dust removing cover, one end of each negative pressure pipe is communicated with the dust removing cover, and the other end of the each negative pressure pipe is communicated with the negative pressure dust removing system. The negative pressure pipes are fixed on a base frame and made of hard materials, a guide cylinder sleeves each negative pressure pipe, the guide cylinders are fixedly connected with the dust removing cover, a drive device is further fixed on the base frame, and the drive device drives the dust removing cover to move up and down relative to the negative pressure pipes. An ash discharging valve is arranged at the connection position between the inner sleeve pipe and the ash hopper, one part of reentrainment dust generated by the cone-shaped material distributor can be blocked by a horn mouth formed at the bottom of the annular dust removing cover and falls into a vehicle compartment again, the other part of the reentrainment dust is absorbed into the dust removing system through the negative pressure pipes, and secondary dust removing is conducted.
Description
Technical field
The utility model be applicable to power plant, iron-smelter blast furnace dedusting system ashes unload grey dedusting.
Background technology
In the present environmental protection field, the blast furnace dedusting system of iron-smelter generally comprises deduster and dust unloadnig apparatus, and grey car is when entrucking, and cinder-discharging port goes out to produce a large amount of airborne dusts, causes second environmental pollution.The deduster that uses at present generally all is the rigidity deduster, and it is bigger to take up room, and grey car easily produces collision by difficulty, causes device damage; And the water pipe of wet dedusting easily freezes in the winter time and can't use, and has that dust-collecting efficiency is low, maintenance is big, the high deficiency of operating cost.
Summary of the invention
The purpose of this utility model is to provide a kind of ash that unloads to use dust arrester, can effectively solve above-mentioned deficiency.The apparatus structure that provides is simple compact, easy for installation, and can effectively reduce the dust in the surrounding environment, the secondary pollution when avoiding unloading ash.
The technical scheme in the invention for solving the above technical problem is:
A kind ofly unload grey dust arrester, it is characterized in that, comprising: the inner sleeve that the upper end can be connected with ash bucket, be located at the below of described inner sleeve lower end dust excluding hood, be connected in tripper, the negative pressure pipe that an end is communicated with described dust excluding hood and the depression dust-removing system that is communicated with the other end of described negative pressure pipe of dust excluding hood bottom.
Describedly unload grey dust arrester, it is characterized in that: described negative pressure pipe is fixed on the underframe, described negative pressure pipe is that hard material is made, and be with a guide cylinder on each described negative pressure pipe, described guide cylinder is all fixedlyed connected with described dust excluding hood, drive unit is also fixedly arranged on the described underframe, and described drive unit drives the relative negative pressure pipe of described dust excluding hood and moves up and down.
Describedly unload grey dust arrester, wherein: be provided with four described negative pressure pipes around described inner sleeve.
Describedly unload grey dust arrester, wherein: described drive unit drives two or more cylinders and rotates synchronously, and described cylinder links to each other with described guide cylinder or annular dust excluding hood by steel wire rope again.
Describedly unload grey dust arrester, wherein: described tripper is the taper tripper.
Describedly unload grey dust arrester, wherein: described annular dust excluding hood bottom is provided with horn mouth.
Describedly unload grey dust arrester, wherein: described inner sleeve and ash bucket junction are provided with unloading valve.
The operation principle that the utility model unloads grey dust arrester is:
Compared with prior art, advantage of the present utility model is:
1, annular dust excluding hood bottom is provided with horn mouth, and top is provided with the negative pressure pipe.The airborne dust that the tripper place produces, a part can be stopped and fall in the compartment that a part sucks dust pelletizing system by bell-mouthed inclined-plane under suction function.
2, be provided with the taper tripper in the middle part of the annular dust excluding hood, dust can slow down its sinking speed and fallen in the compartment its uniform branch through out-of-date.
3, annular dust excluding hood top is provided with four negative pressure pipes, has guiding and dust suction effect concurrently.

Fig. 1 is the front view that unloads grey dust arrester;
Fig. 2 is the vertical view that unloads grey dust arrester.
Description of reference numerals: 1 unloading valve; 2 cylinders; 3 underframe; 4 inner sleeves; 5 negative pressure pipes; 6 guide cylinders; 7 annular dust excluding hoods; 8 taper trippers; 9 horn mouths; 10 drive units.
The specific embodiment
Above embodiment describes the utility model; but not the summary of being restricted property; those of ordinary skills are under the guidance of inventive concept of the present utility model; can also make modification and replacement on a lot of conventional structures, these are revised with replacement and also should be considered to belong among the protection domain of the present utility model.
The utility model provides unloads grey dust arrester, as shown in Figure 1 and Figure 2, comprising: inner sleeve, the annular dust excluding hood of being located at the below of described inner sleeve lower end that the upper end can be connected with ash bucket by unloading valve, be connected in taper tripper, the negative pressure pipe that an end is communicated with described dust excluding hood and the depression dust-removing system that is communicated with the other end of described negative pressure pipe of annular dust excluding hood bottom;
In the present embodiment, be provided with four described negative pressure pipes around described inner sleeve, four described negative pressure pipes are fixed on the underframe, described negative pressure pipe is that hard material is made, and be with a guide cylinder on each described negative pressure pipe, described guide cylinder is all fixedlyed connected with described dust excluding hood, drive unit is also fixedly arranged on the described underframe, described drive unit drives two or more cylinders and rotates synchronously, described cylinder links to each other with annular dust excluding hood (also can be described guide cylinder) by steel wire rope again, by the driving of described drive unit, drive the relative negative pressure pipe of described annular dust excluding hood and move up and down.
When dust unloadnig apparatus unloads ash, start drive unit drive cylinder and steel wire rope annular dust excluding hood and taper tripper are reduced to bottom, grey car compartment; Open unloading valve, the dust in the ash bucket drops on the taper tripper through inner sleeve, evenly falls into grey car then; Along with the increase of dust height in the grey car compartment, constantly annular dust excluding hood is risen, be convenient to continue the dress ash; The reentrainment of dust part that taper tripper place produces can be stopped by the horn mouth that described annular dust excluding hood bottom arranges and fall into again in the compartment, and another part then sucks dust pelletizing system by the negative pressure pipe and carries out final dusting.
As seen, the utility model is simple and compact for structure, maintenance rate is low, and the dust in the environment around making significantly reduces, and reduces second environmental pollution, need not existing equipment is carried out big change, and is easy to implement.
