Abstract
The utility model relates to a water -cooled returning charge hyoplastron, including hyoplastron body, round pin post and water -cooling pipe, the hyoplastron body comprises two hyoplastrons, is equipped with round pin post hole on the hyoplastron body, and together fixed with two hyoplastrons through round pin post and welding mode, the inner face that is connected at two hyoplastrons is equipped with the pipe passageway, installs the water -cooling pipe in the pipe passageway between two hyoplastrons to the water -cooling pipe is as hanging the support. The beneficial effects of the utility model are that: simple structure, it is easy to make, simple to operate, prevents that the returning charge hyoplastron from taking place to warp or drop at the in -process of operation, has prolonged the life of returning charge hyoplastron. Reduce the number of times that maintains the returning charge hyoplastron, reduced the maintenance cost of boiler, improved the availability factor of boiler.
Description
Technical field:
The utility model relates to a kind of water-cooled returning charge tongue plate, belongs to boiler manfacturing technical field.
Background technology:
Along with environmental requirement increasingly stringent, circular fluid bed is one of high-efficiency low-pollution coal combustion equipment practical and the most feasible at present. Circulating fluidized bed combustion is the clean-burning technology of a kind of novel efficient, low stain, principal feature is containing a large amount of materials in stove, coal-fired occupancy volume is the 3-5 of material, in the process of burning, a large amount of materials is taken to upper furnace by flue gas, through the separator being arranged in furnace outlet by feed separation, and through anti-glassware, material is sent back in stove, carry out repeatedly circulating combustion. And the key part returning charge tongue plate as material returning device, it mainly acts on is the circulation controlling material, ensures that material can normally return in stove, and whether it is durable in use in operational process, is a big realistic problem. In existing circular fluid bed, returning charge tongue plate mainly contains several structure: 1, quarl structure; 2, refractory castable structure; 3, Heat resisting cast steel structure. But from practical operation situation, quarl structure and refractory castable structure also exist abrasion and come off problem, and Heat resisting cast steel structure also exists problem on deformation. What the time was short also just there will be the problems referred to above with regard to 3-4 month, cause the revert system of boiler that exception often occurs, can not normally returning charge, and then the whole recycle system causing boiler is abnormal, boiler can not normally be run, often it is forced to shutdown maintenance change, adds maintenance cost and the time of boiler, decrease the working time of boiler. Bring huge financial loss to user simultaneously.
Summary of the invention:
The utility model object is the deficiency in order to overcome existing returning charge tongue plate, it is provided that a kind of long service life, it is not necessary to the often water-cooled returning charge tongue plate of maintain and replace.
The utility model solves the technical scheme that its technical problem adopts:
A kind of water-cooled returning charge tongue plate, comprise tongue plate body, pin and water-cooled pipe, tongue plate body is made up of two blocks of tongue plates, tongue plate body is provided with pin hole, by pin and welding process, two panels tongue plate is fixed together, the interior face being connected at two blocks of tongue plates is provided with tube passage, is provided with water-cooled pipe in the tube passage between two panels tongue plate, supports using water-cooled pipe as hanging.
Described two blocks of tongue plates are symmetrical, are provided with 45 ° of grooves in the inner side bottom of every block tongue plate.
Described tongue plate body is rectangle steel plate, and bottom is the semicircle of radius 60mm, and top is provided with groove, is provided with the boss that 10mm width 20mm is high in the both sides of groove.
Described pin hole is staggered arrangement on tongue plate body, in order to install pin.
Described tongue plate body supports using water-cooled pipe as hanging, tongue plate body and water-cooled pipe is connected and fixed by pin simultaneously.
The beneficial effects of the utility model are: structure is simple, easy to manufacture, easy for installation, prevent returning charge tongue plate from deforming or dropping in the process run, and extend the work-ing life of returning charge tongue plate. Decrease the number of times of maintenance returning charge tongue plate, reduce the maintenance cost of boiler, it is to increase the service efficiency of boiler.
