Now need each root heat exchanger tube of a kind of set of heat exchange tubes of the waste heat boiler that can use the hot stove in ore deposit to carry out the guider of accurately fixing and location, can make location, heat exchanger tube position accurately, and the not influence of expanded by heating.
The utility model content
For each root heat exchanger tube of solving the set of heat exchange tubes under the prior art when it is installed, be difficult to guarantee the spacing between the heat exchanger tube, and then had influence on the deashing brush row who carries out deashing work and can not move up and down freely, influence the normal operation of deashing mechanism, also just influence ash-removal effect and influence exerting oneself of waste heat boiler then.
The utility model provide the hot stove in a kind of ore deposit with the set of heat exchange tubes of waste heat boiler with fixing and guider, by this device is set, make the expansion displacement of heat exchanger tube be confined to the axial of heat exchanger tube, and expansion displacement downwards.Guarantee the spacing of heat exchanger tube and then guaranteed moving up and down freely of deashing brush row.Concrete structure of the present utility model is as described below:
The hot stove in a kind of ore deposit reaches guider with the set of heat exchange tubes of waste heat boiler with fixing, and comprises waste heat boiler and is installed in the interior set of heat exchange tubes of this waste heat boiler, it is characterized in that:
The described set of heat exchange tubes that is installed in the waste heat boiler is provided with a fixing and guider in the lower end of this set of heat exchange tubes.
According to set of heat exchange tubes fixing and the guider of the hot stove in a kind of ore deposit of the present utility model with waste heat boiler, it is characterized in that, the described fixing guider that reaches comprises the heat-exchanging tube bundle group, the tube bank backplate, locating pin and positioning beam, it is specially, the heat-exchanging tube bundle group is suspension type and is fixed on the boiler top cross-bar, every heat exchanger tube of set of heat exchange tubes is all aimed at every tube bank of heat-exchanging tube bundle group, and heat exchanger tube inserts in the corresponding tube bank, the tube bank backplate is arranged at the elbow, bottom of heat-exchanging tube bundle group and welds with this elbow, welding is provided with the locating pin of a round steel type below this tube bank backplate, in the spacing hole on the positioning beam below the bottom of this sliding pin is inserted and is arranged at.
According to set of heat exchange tubes fixing and the guider of the hot stove in a kind of ore deposit of the present utility model with waste heat boiler, it is characterized in that, the locating pin of described round steel type, its sliding pin diameter is 15mm～25mm, sliding pin length is 150mm～300mm.
The purpose of this design is; heat exchanger tube is inserted in the corresponding tube bank; promptly equal fixed-site with each heat exchanger tube; can not hinder moving up and down of deashing brush row; and the tube bank backplate has worked to adjust and locate the bottom elbow of tube bank group and protection heat-exchanging tube bundle group; in addition; the locating pin that is positioned at tube bank backplate below and welds with the tube bank backplate; fixed-site with the tube bank backplate; and in the spacing hole on the positioning beam below the bottom of this locating pin is inserted and is arranged at; the restriction tube bank is rocked and lateral displacement, with the whole fixing bottom that guider is fixed on waste heat boiler that reaches.
