Abstract
The utility model discloses a head coal flow regularizing device for a coal conveying belt used in a thermal power plant. The head coal flow regularizing device comprises an arc-shaped flow regularizing baffle plate and a lead screw, wherein one end of the flow regularizing baffle plate is movably linked to a drum head shield over a belt drum; one end of the lead screw is movably connected with the flow regularizing baffle plate; the other end of the lead screw passes through a guide barrel fixed to the drum head shield, and is connected with a nut. The head coal flow regularizing device has the advantages that 1, the angle of the flow regularizing baffle plate is changed by adjusting the nut on the lead screw in order to ensure that coal flow is guided to the middle of a head hopper under different force application conditions without impacting the wall surface of the head hopper; 2, the impact and vibration of a dropping coal pipe of the head funnel are reduced, thereby preventing looseness of a mounting flange and reducing raise dust; 3, the head coal flow regularizing device is arranged on the head shield, and can be replaced by only detaching the head shield without influencing normal running of a coal conveying system when the flow regularizing device is worn; meanwhile, the flow regularizing baffle plate is small in size, thus the manufacturing and running costs of the flow regularizing baffle plate are much lower than the replacement cost of the impacted wall surface of the head hopper.
Description
Technical field
The utility model relates to a kind of thermal power plant coal conveyer belt head coal stream neatening device, relates in particular to a kind of thermal power plant coal conveyer belt head coal and fall into the coal stream neatening device at former coal bunker position.
Background technology
At present; coal thermal power generation corporations; for reducing raw materials for production cost; conventionally use meager coal generating inferior; because raw coal quality is poor; wherein often be mixed with a large amount of wooden units, stone and coal humidity high viscosity large; therefore serious impact and wearing and tearing head hopper walls in the time that coal stream falls into head funnel from coal conveyer belt head; although the impact wall of head funnel adopts wear-resisting steel to make conventionally; but because seriously causing, impact wear changes frequently; not only affect coal handling system and normally moved, also increased maintenance intensity, improved operating cost.
Summary of the invention
The purpose of this utility model be to provide a kind of make the coal stream of coal conveyer belt under difference is exerted oneself diversed enter head funnel center, and the thermal power plant's coal conveyer belt head coal stream neatening device its wall not being impacted, the utility model can by adjusting angle make coal stream diversed enter head funnel center, reduced the impact endurance test shock of head funnel dropping coal tube simultaneously, thereby prevent the loosening of mounting flange, reduce airborne dust.
The technical solution of the utility model is:
A kind of thermal power plant coal conveyer belt head coal stream neatening device, comprise arc rectification baffle plate and screw mandrel, it is characterized in that, on the cylinder head cover of one end active link of rectification baffle plate directly over belt roller, one end of screw mandrel is flexibly connected with rectification baffle plate, and the other end of screw mandrel is connected with nut through the guide cylinder being fixed on cylinder head cover.
In order to obtain better technique effect, guide cylinder is movably arranged on the support being fixedly mounted on head cover; Guide cylinder is T-shaped, the strip shape guide groove that has guide cylinder to move on head cover; On guide cylinder, there is packing seal, block the connecting sewing of cylinder head cover and guide cylinder; Rotation otic placode is housed on rectification baffle plate, and screw mandrel is movably connected on rotation otic placode by bearing pin; There is hog frame at the back of rectification baffle plate.
The utility model has the advantage of: 1, by regulating the nut on screw mandrel, the angle that changes rectification baffle plate with ensure belt coal stream under difference is exerted oneself operating mode diversed enter the center of head funnel, and its wall is not impacted; 2, reduce the impact endurance test shock of head funnel dropping coal tube, thereby prevented the loosening of mounting flange, reduced airborne dust; 3, this device is arranged on head cover, in the time that its wearing and tearing need to change, only head cover need to be dismantled, do not affect the normal operation of coal handling system, because the area of rectification baffle plate is less, its making and operating cost are well below the impact wall of changing head funnel simultaneously.

Detailed description of the invention
Embodiment 1
A kind of thermal power plant coal conveyer belt head coal stream neatening device, comprise arc rectification baffle plate 1 and screw mandrel 7, one end of rectification baffle plate 1 is by the cylinder head cover of hinge 8 active links directly over coal conveyer belt cylinder 12, one end of screw mandrel is flexibly connected with rectification baffle plate, the other end of screw mandrel is connected with nut 13 through the guide cylinder 6 being fixed on cylinder head cover 9, and guide cylinder 6 is movably arranged on the support 5 being fixedly mounted on cylinder head cover 9; On guide cylinder 6, there is packing seal, block the connecting sewing of cylinder head cover 9 and guide cylinder 6; Rotation otic placode 3 is housed on rectification baffle plate 1, and screw mandrel 7 is movably connected on rotation otic placode 3 by bearing pin 2; There is hog frame at the back of rectification baffle plate 1, and hog frame is formed by connecting in length and breadth by steel pipe.
When work, adjust the length of screw mandrel 7 by rotating nut 13, and then the angle of adjustment rectification baffle plate, make coal conveyer belt coal stream under difference is exerted oneself operating mode diversed enter the center of head funnel, and avoid clashing into raw coal hopper walls 10, in adjusting rectification baffle plate angle, guide cylinder is along with the angle of screw mandrel changes and rotation variation.
Embodiment 2
As optimization, guide cylinder 6 ' is T-shaped, has the mobile strip shape guide groove 11 of guide cylinder 6 ' on cylinder head cover 9; Other are with embodiment 1.
When work, adjust the length of screw mandrel 7 by rotating nut 13, and then the angle of adjustment rectification baffle plate, make coal conveyer belt coal stream under difference is exerted oneself operating mode diversed enter the center of head funnel, in adjusting rectification baffle plate angle, the screw mandrel length between nut and rectification baffle plate changes, can be by adjust the position of guide cylinder along guide groove, packing seal is installed on guide cylinder, and packing seal covers in guide groove, avoids coal dust to overflow and affects working environment.
