Abstract

The invention relates to thermal engineering, and more particularly to furnace grate designs, and can be used in various furnace systems, in particular thermal generators. In a furnace grate design comprising grate bars and stoking members which are connected to an electric motor, according to the invention the stoking members are configured in the form of elements encompassing the grate bars and having depressions along their sides and are mounted for reciprocating motion on the shaft of a crank mechanism with an eccentric for each stoking member, thus providing for countermotion. The proposed furnace grate design, which is significantly simpler than the known prior art, makes it possible to improve the operation of the device and the possibility of repair.

Description

КОЛОСНИКОВАЯ РЕШЕТКА  GRATE
Изобретение относится к теплоэнергетике, в частности к конструкциям колосниковых решеток, и может быть использовано в различных топочных устройствах, в частности, в теплогенераторах. Известна беспровальная колйсшшэваялэешетка, полотно которой состоит из чередующихся т-образных и крестообразных колосников, между кото- рыми имеются зигзагообразные щели для прохода дутьевого воздуха (а.с. 79825, кл. F23H17/12, оп.01.01.49г.). Фигурная форма колосников выполнена таким образом, что они зацепляют друг друга, создавая единую конструкцию. Это затруднит ремонт решетки, так как для замены, например одного колосника, необходимо будет снять всю решетку. The invention relates to a power system, in particular, to designs of grates, and can be used in various furnace devices, in particular, in heat generators. There is a well-known non-woven kolayshshevayaleeshhetka, the canvas of which consists of alternating T-shaped and cross-shaped grate-bars, between which there are zigzag slots for the passage of blast air (A.S. 79825, class F23H17 / 12, 01.01.01.49). The curved shape of the grate is made in such a way that they engage each other, creating a single design. This will make it difficult to repair the grate, since to replace, for example, one grate, it will be necessary to remove the entire grate.
Известна колосниковая решетка топки с шурующей планкой, снабженная опускающимися и поднимающимися при помощи эксцентрика колосниковыми плитками (а.с.91770, кл. ' F23H9/06, оп.01.01.51г.). Данная колосниковая решетка имеет сложное конструкционное решение. Наличие множества подвижных частей при высокой температуре в топке может вы- звать их поломку. Known grate furnace grate with a shuruyuyu leveling, equipped with lowering and rising using an eccentric grate tiles (A.S. 91770, class. ' F23H9 / 06, op.01.01.51g.). This grate has a complex structural solution. The presence of many moving parts at high temperature in the furnace can cause them to break.
Известна также колосниковая решетка, содержащая балочные колосники, установленные с возможностью поворота, и шурующую планку. Конструкция содержит водоохлаждаемые трубы, расположенные между колосниками, и выполненные прямыми или в виде змеевиков, при этом верхние образующие труб расположены в плоскости, лежащей ниже рабочей поверхности решетки (a.c. l 520304,Kn.F23H9/10, on.07.1 1.87г.). Наличие системы водоохлаждаемых труб, соединенных с коллекторами, существенно усложняет конструкцию и затрудняет выполнение ремонтных работ. Also known is a grate, containing beam grates installed with the possibility of rotation, and a screwing bar. The design contains water-cooled pipes located between the grates, and made straight or in the form of coils, with the upper generatrix of the pipes located in a plane lying below the working surface of the grate (ac l 520304, Kn.F23H9 / 10, on.07.1 1.87). Availability systems of water-cooled pipes connected to the collectors significantly complicates the design and complicates the repair work.
Задачей предлагаемого изобретения является разработка колосниковой решетки более простой конструкции, обеспечивающей эффективную работу и удобство в эксплуатации и ремонте. The task of the invention is to develop a grate of a simpler design that provides efficient operation and ease of operation and repair.
Для этого в конструкции колосниковой решетки, содержащей балочные колосники и шурующие приспособления, соединенные с электродвигателем, согласно изобретению шурующие приспособления выполнены в виде охва- тывающих балочные колосники элементов с выемками по бокам, установ- ленные с возможностью возвратно-поступательного движения на валу кри- вошипного механизма с эксцентриками на каждое шурующее приспособле- ние с обеспечением противохода. To this end, in the construction of the grate, containing grate grates and screwing devices connected to the electric motor, according to the invention, the screwing gages are made in the form of elements covering the grate grates with recesses on the sides, mounted with the possibility of reciprocating movement on the crank shaft mechanism with eccentrics for each shuruyuschey device with the provision of counter-flow.
В конструкции колосниковой решетки соотношение длины балочного колос- ника и шурующего приспособления составляет 1 :0,9-0,95. Площадь выемок шурующего приспособления составляет 15-30% от площади шурующего приспособления. In the design of the grate, the ratio of the length of the grate and the screwing device is 1: 0.9-0.95. The area of the recesses of the screwing device is 15-30% of the area of the screwing device.
На фиг.1 чертежа изображена предлагаемая колосниковая решетка - вид сбоку, на фиг.2 - вид сверху, на фиг.З - общий вид. В отопительном котле 1 установлена колосниковая решетка 2, имеющая балочные колосники 3, например, в виде цилиндров - труб, по которым подается вода через трубы 4, и шурующие приспособления 5, выполненные в виде охватывающих балочные колосники 3 элементов - поверх жестко закрепленных колосников 3, с выемками по бокам 6. Вода для охлаждения может быть соединена с системой обогрева, что повысит теплоотдачу, а может быть и независимой. Площадь выемок 6 шурующего приспособления 5 составляет 15-30% от общей его площади. Шурующие приспособления 5 установлены с возмож- ностью возвратно-поступательного движения на валу кривошипного меха- низма 7, соединенного с электродвигателем 8, и с эксцентриками 9 на ка- ждое шурующее приспособление 5 с обеспечением противохода. Для вы- полнения хода шурующих приспособлений 5 соотношение длины балочного колосника 3 и шурующего приспособления 5 составляет 1 :0,9-0,95. Figure 1 shows the proposed grate; a side view, figure 2 is a top view, Fig. 3 is a General view. In the heating boiler 1, a grate 2 is installed, having girder grates 3, for example, in the form of cylinders - pipes through which water is supplied through pipes 4, and screwing devices 5, made in the form of elements covering the grate grates 3 - on top of the rigidly fixed grates 3, with recesses on the sides 6. Water for cooling can be connected to the heating system, which will increase heat transfer, and can be independent. The area of the recesses 6 of the screwing device 5 is 15-30% of its total area. The screwing devices 5 are mounted with the possibility of reciprocating motion on the shaft of the crank a casing 7 connected to an electric motor 8, and with eccentrics 9 to each screwing device 5 with a countercurrent. To perform the stroke of the screwing devices 5, the ratio of the length of the beam grate 3 and the screwing device 5 is 1: 0.9-0.95.
Работа предлагаемой конструкции осуществляется следующим образом. В котле 1 на колосниковую решетку 2 подают топливо, в процессе горения то- плива для стряхивания золы включается электродвигатель 10 и посредством возвратно-поступательных движений шурующих приспособлений 5 в ре- жиме противохода, и за счет выемок по их бокам, осуществляется эффек- тивный сброс частиц золы. The work of the proposed design is as follows. In the boiler 1, fuel is supplied to the grate 2, during the combustion of the fuel to shake off the ash, the electric motor 10 is turned on and by reciprocating movements of the screwing devices 5 in the counterflow mode, and due to the recesses on their sides, an effective discharge is performed particles of ash.
Таким образом, предлагаемая конструкция колосниковой решетки, кото- рая значительно проще известных аналогов, позволяет улучшить эксплуата- цию устройства и возможность ремонта. Thus, the proposed design of the grate, which is much simpler than the known analogues, allows to improve the operation of the device and the possibility of repair.
