Description
Technical Field
The invention belongs to the technical field of raw material resource-saving type dust collectors, and particularly relates to a dust collector of a mixer with a dust synchronous recovery type, which enables dust collected by the dust collector to synchronously return to a mixer.
Background
When a brick making enterprise is provided with a plurality of blenders, dust generated in the production process of the mixed materials by the blenders is sucked and collected by the same dust remover.
Because the material formulas of the several material mixers are different at the same time, the material proportion of the dust collected by the dust remover has no definite parameter, so that the dust collected by the dust remover becomes waste.
Even if the same mixer is used, the material formula is switched at any time due to production requirements, and if dust of materials with different formulas is collected by a dust remover, the dust is also changed into waste materials with material proportion without determined parameters.
If about 1200 tons of dust (waste) are collected every year, the value is about 600-1400 ten thousand yuan per year according to the price of 5000-7000 yuan per ton of raw materials. This wastes a lot of natural resources (huge waste of raw materials) and causes huge losses for enterprises.
No dust remover for synchronously recycling dust performance exists in domestic and foreign markets.
The filter element is a filter bag (a framework is arranged in a filter cloth bag, which is the known technology) or a dust remover of a filter cartridge, one of the key factors of the dust removal efficiency is the effect of back-flushing and dust removing after dust is accumulated on the surface of the filter bag or the filter cartridge, and the most key component for ensuring the dust removing effect to meet the design requirement is a back-flushing nozzle.
Dust collectors of other companies in the market at present use circular tubes 41 with different diameters and lengths of 30-50 mm as back-blowing nozzles as shown in fig. 19, the back-blowing gas flow from a common nozzle is narrow as shown in fig. 19 (a), the narrow injection effect of the high-pressure gas flow of the common nozzle is not obvious, the amount of gas injected into a cloth bag is small, the venturi nozzle is installed at the inlet of the cloth bag as shown in fig. 19 (b), the gas flow is limited, and the back-blowing effect is very poor as shown in fig. 19 (c), and is mainly shown in the following steps: the bag is not completely pasted during the ash removal, the blowing direction deviates to blow the cloth bag, and the shaking amount is small due to the fact that the quantity of gas entering the cloth bag is small and the cloth bag is not expanded obviously, so that the ash removal effect is not obvious and the like.
The filter element is a filter bag or a filter cartridge dust remover, one of the key factors of the dust removal efficiency is the effect of back-blowing and dust removal from the inlet of the filter bag after dust is deposited on the surface of the filter bag or the filter cartridge, so as to ensure that the dust removal effect reaches the design requirement,
the tightness of the blow-back pipe socket for the connection between the air supply solenoid valve and the blow-back pipe is very important for this.
At present, no back flushing pipe socket commodity of the design exists in the market, dust collectors manufactured by other companies have various and crude connections between a back flushing pipe and an electromagnetic valve, and the defects of the crude connection modes are mainly shown as follows: air leakage is very serious, and the dust cleaning effect of the cloth bag or the filter cylinder is seriously influenced.
The air leakage between the air cylinder and the electromagnetic valve is easy to occur.
Disclosure of Invention
The invention aims to provide a dust collector of a mixer with a dust synchronous recovery function, which can synchronously return dust collected by the dust collector into the mixer.
The technical scheme is as follows:
a dust collector of a dust synchronous recovery type mixer comprises a dust collector shell and a plurality of filter pieces.
The inside top of dust remover casing is equipped with the filter mounting panel of horizontal setting, offers a plurality of holes on the filter mounting panel, and filter is installed in every hole.
The technical key points are as follows:
the inlet of the dust inlet pipe is connected with a dust collector air inlet bin of the dust collector shell.
And paired guide plates are arranged between the filter pieces.
The air inlet bin outlet of the dust remover is corresponding to each pair of guide plates.
The guide plate is arranged below the filter piece mounting plate.
The pipeline at the top of the dust remover shell is connected with an inlet of an external fan.
The dust outlet of the dust remover at the bottom of the dust remover shell is provided with a dust remover outlet pipeline.
The dust remover shell is internally provided with a Venturi nozzle back-blowing structure.
And the air inlet of at least one back flushing pipe is connected with the corresponding electromagnetic valve through a back flushing pipe socket.
The sub-cylinder is connected with at least one electromagnetic valve through corresponding loose joints.
The inlet of the dust inlet pipe is connected with at least one section of pipeline and is used for being connected with a plurality of points generating dust.
The advantages are that:
after dust generated in the process of mixing materials by the mixer is collected by the dust remover (preventing environmental pollution), the dust is also collected by the dust remover
The step is returned to the mixer, so that three problems are solved, namely, the dust is prevented from polluting the environment, the parameters of the original material proportion are not changed, and the raw materials are prevented from losing.
A common dust inlet pipe is arranged at the middle lower part of a dust remover shell, and the dust inlet pipe is arranged above the dust remover shell.
The high-pressure gas (a part in fig. 5) blown back from the venturi nozzle is ejected by the high-pressure gas of the nozzle, and the surrounding air is exploded and impacted forwards along the ejection direction together according to the venturi principle, so that the blown gas is amplified, the blowing capacity is doubled, and a better dust removal and blowing effect on the surface of the filter element is achieved, as shown in a part b in fig. 5. The venturi principle is utilized to strengthen the blowing air flow, and the air blowing device has the characteristics of increased back blowing air quantity, strong directionality and uniform distribution of the back blowing air quantity of each filter cloth bag, thereby obtaining the best blowing effect.
The back-flushing pipe socket has the advantages of advanced structure, convenient installation (the connection with the wall plate of the dust remover, the connection with the air outlet of the electromagnetic valve and the connection with the back-flushing pipe are very simple), and the most important is that the sealing performance is good and air tightness is not leaked, thereby obtaining the best blowing effect.
The slipknot is convenient to install and good in sealing performance.
