Description

High-efficient dust collector of cement jar of easy installation maintenance

Technical Field

The utility model relates to a dust collector, in particular to high-efficient dust collector of cement jar of easy installation maintenance.

Background

Along with the progress of national infrastructure, the consumption of premixed concrete for construction is increased, and the environmental protection pressure of each concrete production enterprise is also increased; at present, most concrete manufacturers take measures for reducing cement dust pollution by installing a dust remover on the top of a cement tank to remove dust and reduce dust; the dust remover is arranged at the top of the cement bin, the bottom of the dust remover is connected with the cement bin, and the upper part of the dust remover is directly discharged to the atmosphere; the bottom plate in the dust collector is provided with a plurality of (more or less) embedded circular holes, the bottom plate is provided with a plurality of cloth bag filter elements, the cloth bag filter elements are used as filtering materials, when dust-containing gas passes through the filter bag, dust is blocked on the surface of the filter bag, the filter elements are tightly tied on a vibrator hanger at the upper end, the vibrator vibrates at regular time to enable the dust blocked by the filter elements to fall in a bin, and dry air is discharged through gaps among fibers of the filter bag, so that the aim of separating the dust-containing gas is fulfilled; although the dust removal method has good dust removal effect and the using proportion of most commercial concrete mixing plants in China is high, some defects are found in the using process: (1) the gas filtered by the powder separating tank also contains part of cement fine powder, and the part of cement fine powder enters ambient air along with the air exhaust body to pollute the ambient air; (2) the cloth bag filter element in the powder separation tank needs to be replaced periodically, the powder separation tank is arranged on the top of the cement tank, the height of the cement tank is more than 20 meters, and high-altitude operation is needed for replacing the filter element, so that the problems of inconvenient operation and high danger coefficient of the high-altitude operation exist; (3) as the connection of the powder knockout drum and the cement tank body of dust remover, lean on a stainless steel pipe hoop to link together, when the inside filter core of dust remover is whole to be blockked up, if the staff is under the condition of unknown, pour into cement in the cement tank by force, because the air can not discharge smoothly in the jar, can lead to the pipe hoop of stainless steel on the dust collector to be blown away by explosion in the twinkling of an eye, cause serious incident.

Disclosure of Invention

The utility model provides a high-efficient dust collector of cement jar of easy installation maintenance has solved the not ideal technical problem of maintaining with difficult installation of dust removal effect that current cement jar dust collector exists.

The utility model discloses a solve above technical problem through following technical scheme:

the utility model provides a high-efficient dust collector of cement jar of easy installation maintenance, including the cement jar, powder knockout drum and water tank, tank deck at the cement jar is provided with cement jar top gas vent, be provided with powder air inlet and filtration back gas discharge mouth on the powder knockout drum respectively, upper portion is provided with the filter screen in the jar of powder knockout drum, be provided with filtration back gas discharge mouth on the regional jar wall of air escape that the filter screen encloses the shelves, it has water to hold in the water tank, the powder knockout drum sets up the bottom outside at the cement jar, be connected with perpendicular blast pipe on the powder air inlet, the upper end of perpendicular blast pipe is in the same place with cement jar top gas vent intercommunication, be connected with the filtration gas discharge pipe on the filtration back gas discharge mouth, the lower extreme export of filtration gas discharge pipe sets up the aquatic in the water tank.

The bottom of the powder separating tank is provided with a precipitated starch material discharge valve.

The utility model discloses a powder separator simple structure installs in ground position, makes things convenient for the change of operation maintenance and filter screen, and final gas discharges after passing through pond normal water, does not contain the dust in the messenger exhaust gas, has protected the surrounding atmosphere environment, and the site conditions is poor, and the stirring station is changeed the frequent construction enterprise of mobility and is used very much.

fig. 2 is a schematic structural diagram of the powder separation tank 4 of the present invention.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings:

an easy-to-install and maintain efficient dust removal device for a cement tank comprises a cement tank 1, a powder separation tank 4 and a water tank 10, the tank top of the cement tank 1 is provided with a cement tank top exhaust port 2, the powder separation tank 4 is respectively provided with a powder inlet 5 and a filtered gas exhaust port 7, a filter screen 6 is arranged at the upper part in the powder separation tank 4, a filtered gas outlet 7 is arranged on the tank wall of the air exhaust area surrounded by the filter screen 6, the water tank 10 is filled with water 11, the powder separating tank 4 is arranged at the outer side of the bottom end of the cement tank 1, the powder air inlet 5 is connected with a vertical exhaust pipe 3, the upper end of the vertical exhaust pipe 3 is communicated with an exhaust port 2 at the top of the cement tank, a filtered gas discharge pipe 8 is connected to the filtered gas discharge port 7, and a lower end outlet of the filtered gas discharge pipe 8 is disposed in the water 11 in the water tank 10.

A settled starch material discharge valve 9 is arranged at the bottom of the powder separation tank 4; the gas that has the cement dust in the cement jar 1 enters into vertical exhaust pipe 3 through powder air inlet 5, because the proportion of cement dust is greater than gas, the cement dust makes free fall motion in vertical exhaust pipe 3, most deposits the jar bottom of powder knockout drum 4, accessible starch setting material discharge valve 9 discharges outside powder knockout drum 4, along with the flowing of gas's the small part cement dust is filtered by filter screen 6, the filter pressure of filter screen has been alleviateed greatly to this kind of structure, the change frequency of filter screen has been prolonged, gas after filter screen 6 filters, in the water 11 in the water tank 10 is carried to filtered gas discharge pipe 8, remaining dust can sink into the bottom in the gas, by the gaseous exhaust upwards discharge in aqueous of cleaned exhaust, the purpose of dust zero release has been reached.

The utility model discloses a powder knockout drum 4 sets up in the department of 1.5 meters from ground level elevation, and exhaust duct connected mode is flange joint, and the exhaust duct end opening elevation is-1000 millimeters. When the equipment runs, water is injected into the exhaust pool, and the water injection height is at least 500 mm higher than the air outlet of the exhaust pipe; the utility model discloses changed and set up the tradition way of dull and stereotyped vibrator at powder knockout drum 4, saved the investment, the structure is more succinct.
