Technical Field

The invention relates to the field of construction equipment, in particular to an electrostatic dust collector for a construction site.

Background

Along with the continuous development and progress of the construction industry, the development of construction machinery equipment is increasingly advanced, the construction machinery equipment provides various convenience and reliability for the construction industry, impurities such as dust and dust become the most common problems of the construction industry due to the characteristics of the industry, the dust and dust on the construction site can seriously affect the body of workers, various respiratory diseases can be caused once the dust and dust are sucked, the service life of a machine can be shortened when the dust and dust enter the construction machinery, the safety is considered, and in addition, the high requirement of the country on environmental protection at present, a large amount of dust removal equipment is required to be used for purifying air and removing the dust and dust on the construction site.

But most dust collecting equipment can not effectual smooth transmission at present, adopt the method of filtration formula or fountain to clear up impurity such as the dust of building site usually, filtration formula dust collecting equipment causes easily after using a period and crosses filter mesh and blocks up, the gas permeability descends, dust removal effect obviously weakens, need frequently change it and wash, spray formula dust collecting equipment then needs to consume a large amount of water purification resources, and is not environmental protection, therefore current dust collecting equipment is difficult to realize building site's automation and removes dust, can not satisfy people's demand.

Disclosure of Invention

The invention aims to solve the defects in the prior art and provides an electrostatic dust remover for a construction site.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides an electrostatic precipitator for building site, includes rear end open-ended drum, electrostatic generator and the ash bucket of fixed mounting at the drum lower extreme of fixed mounting in drum upper end, the opening with ash bucket intercommunication is seted up to the bottom in the drum, the front end of drum is provided with the air inlet, in the air inlet and the rear end of drum all be provided with the otter board, two rotate between the otter board and be connected with the impeller, in the pivot of impeller extends to the air inlet, just the pivot end of impeller is installed and is used for the discharge device with dust polarization in the air, the first conducting strip of fixedly connected with on the blade of impeller, the symmetry is provided with the second conducting strip with the electrostatic generator coupling on the inner wall of drum.

Preferably, the discharge device comprises a dynamic friction plate and a static friction ring, the static friction ring is fixedly connected to the inner wall of the air inlet, the dynamic friction plates are symmetrically and fixedly connected to the tail end of the output shaft of the impeller through a connecting rod, the dynamic friction plates are in contact with the inner wall of the static friction ring, and static sharp needles are arranged on the side wall of the static friction ring along the circumferential direction.

Preferably, each blade of the impeller is equidistantly provided with a spring, and each spring is coupled with a first conducting strip on the impeller blade.

The invention has the following beneficial effects:

1. by arranging the static electricity generating device, the first conducting strip, the second conducting strip and the impeller, when the air current mixed with dust flows through the cylinder, the air current drives the impeller to rotate, so that the first conducting strip on the blade of the impeller intermittently contacts with the second conducting strip, when the first conducting strip contacts with the second conducting strip, the circuit of the static electricity generating device is switched on, a certain electrostatic field is generated on the blade of the impeller, impurities such as dust and dust mixed with the air current can be adsorbed on the blade, when the first conducting strip is separated from the second conducting strip, the circuit of the static electricity generating device is switched off, the electrostatic field generated by the blade of the impeller disappears, the dust and dust losing floating power can naturally descend under the action of gravity and fall into the dust hopper, thereby realizing the automatic dust removing function of a building site, without using a filter screen, without generating the phenomenon of filter hole blockage, and without consuming a large amount of water purification resources, energy is saved and the environment is protected;

2. through the arrangement of the discharging device, when air flows through, the impeller rotating shaft drives the dynamic friction plate to rotate, so that the dynamic friction plate continuously rubs against the inner wall of the static friction ring, more static electricity is generated on the static friction ring, the static electricity charges can be transferred to the tip part of the static electricity sharp needle due to the tip accumulation effect of the static electricity charges, and when the charge quantity is accumulated to a certain degree, the static electricity sharp needle generates a tip discharging phenomenon, so that dust and dust mixed in air are polarized, and the dust and dust are more easily adsorbed by an electrostatic field generated by the impeller blade;

3. through setting up the spring, in the twinkling of an eye of first conducting strip and second conducting strip contact and disconnection, all have the electric current of rapid change on each spring to pass through, this electric current makes all produce induction magnetic field on each turn of coil of spring, induction magnetic field makes each turn of coil of spring form the unanimous little magnetic coil of direction of magnetization, and then makes the spring reconversion after contracting fast, consequently each spring can produce the shake to the blade vibration of drive impeller promotes the dust of adhesion on the blade and drops.
