Abstract

The utility model discloses a wood block separator which comprises a shell, an inlet and an outlet. An oblique main grid is arranged inside the shell, a wood-block collecting chamber is arranged in one side of the shell, a wood block inlet is arranged between the wood-block collecting chamber and the shell and is located below the higher end of in the main grid, a stop plate and a sensor are arranged inside the wood-block collecting chamber, a motor is arranged outside the wood-block collecting chamber, and automation of wood block separation is realized by an external control system. By the arrangement, impurities like wood blocks, cloth strips and braided fabric can be automatically removed from pulverized coal under the condition of non-stop, jamming of pulverized pipelines is avoided, and stability of the separator in operation is improved.

Description

A kind of wood block separator

Technical field

The utility model relates to coal dust and uses field, particularly relates to a kind of wood block separator.

Background technology

The coal using burns in thermal power plant, all will be by the coal dust of coal grinds powder to increase efficiency of combustion, coal dust is in the process of manufacturing and transport, having the impurity such as wooden unit, gunnysack braid is blended in wherein, the dust that these impurity produce afterwards in burning easily stops up smoke discharging pipe, and has reduced burning of coal value.The structure of existing coal dust wood block separator is on pulverized coal preparation system pipeline, to fill a sieve suitable with pipe diameter; coal dust is filtered; but when being stacked into certain degree, the impurity such as the wooden unit on sieve, cloth will hinder passing through of coal dust; need to shut down cleaning sieve; cause the interruption of coal dust supply, affected the production efficiency of enterprise.

Utility model content

The technical problem that the utility model mainly solves is to provide a kind of wood block separator, can be under non-stop-machine state, and the impurity such as wooden unit in Automatic clearance coal dust, cloth, braid, have avoided powder process pipeline to stop up, and have improved the stability of equipment operation.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of wood block separator is provided, comprise: housing, import and outlet, in described housing, be provided with a skewed main grate, a side at housing is provided with wooden unit collecting chamber, between described wooden unit collecting chamber and housing, be provided with wooden unit entrance, described wooden unit entrance is arranged at the below of a main grate high position, the inside of described wooden unit collecting chamber is provided with a baffle plate, in described baffle plate, be provided with rotating shaft, described rotating shaft drives baffle plate to rotate, the arranged outside of described wooden unit collecting chamber has motor, the motor shaft of described motor drives rotating shaft in baffle plate to rotate, the below of described baffle plate is provided with secondary grid, on the housing of described secondary grid below, also have coal dust refluxing opening, between described baffle plate and secondary grid, be also provided with sensor, the bottom sides of wooden unit collecting chamber is provided with wooden unit outlet, the opposite side of described housing is also provided with air inlet, described air inlet is connected with outside air blast by airduct.

Preferably, described motor below is also provided with decelerator.

Preferably, the rotating shaft in described baffle plate and housing joint are also provided with sealing ring.

Preferably, the corner of described import and outlet is set to rounded corner.

The beneficial effects of the utility model are: the utility model (1), effective foreign material such as the wooden unit, cloth that are mingled with in bug dusting, and avoid pulverized coal channel blocked, improved the stability of equipment operation; (2) wooden unit in bug dusting automatically, the potential safety hazard of having avoided manual operation to bring, has improved operating efficiency.

In accompanying drawing, the mark of each parts is as follows: 1, housing, 2, import, 3, outlet, 4, main grate, 5, wooden unit entrance, 6, wooden unit collecting chamber, 7, baffle plate, 8, secondary grid, 9, coal dust refluxing opening, 10, air inlet, 11, airduct, 12, air blast, 13, motor, 14, decelerator, 15, motor shaft 16, sealing ring, 17, sensor, 18, wooden unit outlet, 19, rounded corner.

The specific embodiment

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.

Refer to Fig. 1, the utility model embodiment comprises:

A kind of wood block separator, comprise: housing 1, import 2 and outlet 3, in described housing 1, be provided with a skewed main grate 4, a side at housing 1 is provided with wooden unit collecting chamber 6, between described wooden unit collecting chamber 6 and housing 1, be provided with wooden unit entrance 5, described wooden unit entrance 5 is arranged at the below of main grate 4 high positions, the inside of described wooden unit collecting chamber 6 is provided with a baffle plate 7, in described baffle plate 7, be provided with rotating shaft, described rotating shaft drives baffle plate 7 to rotate, the arranged outside of described wooden unit collecting chamber 6 has motor 13, the motor shaft 15 of described motor 13 drives the interior rotating shaft of baffle plate 7 to rotate, the below of described baffle plate 7 is provided with secondary grid 8, on the housing of described secondary grid 8 belows, also have coal dust refluxing opening 9, between described baffle plate 7 and secondary grid 8, be also provided with sensor 17, the bottom sides of wooden unit collecting chamber 6 is provided with wooden unit outlet 18, the opposite side of described housing 1 is also provided with air inlet 10, described air inlet 10 is connected with outside air blast 12 by airduct 11.

Operation principle of the present utility model is: the coal dust with impurity enters in housing 1 from import 2, through the screening of main grate 4, the coal dust of fine particle enters outlet 3 places through main grate 4, and the larger wooden unit of particle, cloth, the impurity such as braid are blown into the wind coming to wooden unit collecting chamber 6 by air inlet 10, baffle plate 7 in wooden unit collecting chamber 6 is open mode under normal conditions, wooden unit can fall on secondary grid 8, the coal dust being mingled with in wooden unit flows back to import 2 places by coal dust refluxing opening 9, when the impurity such as the wooden unit on secondary grid 8 are stacked into sensor 17 height, sensor 17 passes to outside control system by signal, control system is sent instruction to motor 13, motor shaft 15 drives the rotating shaft in baffle plate 7 to rotate, now, baffle plate 7 is in closure state, open wooden unit outlet 18, the impurity such as wooden unit are discharged.
