Description

Изобретение относится к горной промышленности и может быть использовано для снижения запыленности воздуха в забоях очистных и подготовительных выработок угольных шахт.The invention relates to the mining industry and can be used to reduce dust in the faces of treatment and preparatory workings of coal mines.

Известен шахтный пылеуловитель ⁵ Known mine dust collector ⁵

ПГУМ, содержащий секции с корпусом, завихрителем с направляющими лопатками и шламоотделйтелем со спрямляющими лопатками D1PGUM containing sections with a casing, a swirl with guide vanes and a sludge separator with straightening vanes D1

Недостаток этого многосекционйо- W го шахтного пылеуловителя заключается в том, что он имеет увеличенные размеры в ширину. Причиной увеличенных размеров его ширины является наличие сбоку пылеуловителя патрубка для ’5 выхода шлама.The disadvantage of this multi-sectional W mine shaft dust collector is that it has increased dimensions in width. The reason for the increased size of its width is the presence on the side of the dust collector nozzle for ’5 sludge outlet.

Наиболее близким технической сущности к предлагаемому является многосекционный шахтный пылеуловитель П15М с секциями, расположенными в вертикальной плоскости, содержащими завихритель с направляющими; лопатками, пыпеотделитель со спрям2 ляющими лопатками и патрубок для выхода шлама, расположенный сбоку, секций [2].Closest to the technical nature of the proposed is a multi-sectional mine dust collector P15M with sections located in a vertical plane containing a swirl with guides; blades, a separator with straightening blades and a nozzle for the exit of sludge located on the side of the sections [2].

Однако известный многосекционный пылеуловитель имеет также большие размеры в ширину, увеличенные по сравнению с диаметром корпуса за счет установки сбоку секций патрубка для выхода шлама.However, the known multi-section dust collector is also large in width, increased compared to the diameter of the housing due to the installation on the side of the sections of the pipe for the exit of the sludge.

Цель изобретения - уменьшение габаритов устройства.The purpose of the invention is to reduce the size of the device.

Эта цель достигается тем, что в пылеуловителе, включающем размещенные друг над другом и объединенные входным патрубком секции, содержащие цилиндрический корпус, завихритель с направляющими лопатками, шламоотделитель со спрямляющими лопатками и шламосборник, последний выполнен в виде установленного заподлицо с корпусами секций соединительного патрубка, один конец которого присоединен к нижней части корпуса верхней секции, а другой - к верхней части корпуса нижней секции, причем относительно продольных осей секций соединительный патрубок установлен со стороны, в которую направлены входные концы верхних лопаток завихрителей.This goal is achieved by the fact that in the dust collector, which includes sections arranged one above the other and connected by the inlet pipe, containing a cylindrical body, a swirl with guide vanes, a sludge separator with straightening vanes and a sludge collector, the latter is made in the form of a flush mounted with the case sections sections of the connecting pipe, one end which is attached to the lower part of the housing of the upper section, and the other to the upper part of the housing of the lower section, and with respect to the longitudinal axes of the sections connecting pat the side is installed on the side into which the input ends of the upper blades of the swirlers are directed.

Claims

The invention relates to the mining industry and can be used to reduce the dust content of the air in the openings of mining and preparatory workings of coal mines. The shaft dust collector of the PGUM, containing sections with a hull, a swirler with guide vanes and a sludge separator with dispensing til blades, is known. The disadvantage of this multisection mine dust collector is that it has increased width widths. The REASON of the increased size of its width is the presence of a lateral dust collector pipe for sludge. The closest to the technical essence of the present invention is the P15M multi-compartment mine trap with sections located in a vertical plane, containing a swirler with the directions: blades, a dust separator with rectifying blades and a branch pipe for the sludge outlet, located on the side, sections 2. However, the well-known multisection dust collector also has large widths, enlarged in comparison with the case diameter by installing side sections of the nozzle for sludge outlet. The purpose of the invention is to reduce the size of the device. This goal is achieved by the fact that in a dust collector comprising sections placed above each other and joined by an inlet pipe, containing a cylindrical body, a swirler with guide vanes, a slime separator with spraying blades and a sludge trap, are made in the form of an inlet pipe that is flush with the sections. , one end of which is attached to the lower part of the upper section housing, and the other to the upper part of the lower section housing, moreover, with respect to the longitudinal axes of the connecting sections, The tubes are installed on the side to which the input ends of the upper vanes of the swirlers are directed. FIG. 1 shows a dust collector; la fig. 2 is a section AA in FIG. one; in fig. 3 shows a section BB in FIG. 1. The separator contains vertically arranged cylindrical sections 1, combined with an inlet nozzle 2. Each of the cylindrical sections 1 consists of a casing 3, a swirler 4 with a sleeve 5 and directional vanes 6, a slurry separator 7 with a conical shell 8 and spraying blades 9. Nnogosektsionny mine psheulovitel contains two or more cylindrical sections 1 (the invention is given on the example of two-section mine dust of the catcher). Between the housings 3 against the sludge separator 7, a connecting nozzle 10 is installed flush with the housings. One end of the nozzle is connected to the lower part of the upper case 3, and the second end to the upper part of the lower crust 3. The connecting pipe 19 relative to the longitudinal axes 1 of the sections 1 is installed on the side The output ends of 12 vertebral blades 6 of the swirlers 4 are directed to the hull. The operation of the multisectional mine pitcher proceeds as follows. The fans of the dust removal unit of the installation air with dust and water is fed to the multisection mine dust collector. From the inlet 2, the air enters the cilidric. section 1, where the guide vanes 6 swirlers 4 acquire a rotational-translational motion. Under the action of the centrifugal force that has arisen, the dust with water is separated from the air, the air OUTLETS from the multistage mine dust collector, and the ash and water in the form of psham enters the annular 44 hole 13 between the casing 3 and the sludge trap 7. The slurry from the upper section passes through the vertical connecting pipe 10 to the lower section 1 and then exits the dust collector and drains onto the production soil. Since the connecting cartridge 10 is installed flush with the housings 3, the dust collector performs its functions (dedusting and sludge separation) without increasing its dimensions in width, which makes it easier to operate. The invention includes a cylindrical housing, sections placed above each other and connected by the inlet pipe, containing a cylindrical body, a swirler with guide vanes, a conical slurry separator with guide vanes and a sludge collector, characterized in that, in order to reduce the size of the device, a separator is equipped with a vacuum tank, characterized by the fact that, in order to reduce the size of the device, a separator is equipped with a vacuum collector, characterized in that, in order to reduce the size of the device, the separator is equipped with a vacuum collector, characterized in that, in order to reduce the size of the device, a separator is equipped with a vacuum collector, characterized in that, in order to reduce the size of the device, the separator is equipped with a separator. form flush with the sections of the connecting pipe, one end of which is attached to the lower part of the upper section, and the other to the upper part of the lower section, and with respect to the longitudinal axes of the section, the connecting pipe is installed on the side to which the input ends of the upper vanes of the swirlers are directed.
