For making the plate device of bed in fluidized-bed reactor
Technical field
The utility model relates to the technical field that in fluidized-bed reactor, bed makes.
Background technology
Be provided with two or more bed in many beds fluidized-bed reactor, the structure of each bed comprises: some short tubes, are fixedly welded with connecting plate between adjacent tubes.It is be welded to successively between adjacent short tube by the connecting plate in each bed respectively that traditional bed makes, and the defect of this preparation method is: cannot ensure that short tube corresponding in each bed is concentric, thus affect installing of whole fluidized-bed reactor heating tube.
Utility model content
The purpose of this utility model is: provide the short tube of correspondence in each bed of a kind of energy guarantee concentric and the plate device for making bed in fluidized-bed reactor facilitating each bed to make.
For achieving the above object, the technical solution adopted in the utility model is: for making the plate device of bed in fluidized-bed reactor, comprise: circular fixed mount template, circular fixed mount template is evenly densely covered with some jacks, the distance of adjacent receptacle is identical with the distance of adjacent tubes in bed, plug-in unit is provided with in each jack, the structure of each plug-in unit comprises: for the upper intubate of socket joint short tube, the bottom of upper intubate is fixedly connected with lower intubate, the external diameter of upper intubate and the internal diameter of bed short tube adapt, and upper intubate and bed short tube closely cooperate, the lower external diameter of intubate and the aperture of jack adapt, and lower intubate and jack closely cooperate, on, lower intubate is all concentric with jack, lower intubate is inserted in jack until the outer face, bottom of upper intubate is resisted against the surface of circular fixed mount template.
Further, the aforesaid plate device for making bed in fluidized-bed reactor, wherein, in each plug-in unit the outer face, bottom of upper intubate and the surface of fixed mount template all horizontally disposed.
Further, the aforesaid plate device for making bed in fluidized-bed reactor, wherein, the bottom port outer wall of the lower intubate of each plug-in unit is formed slopely groove.
The utility model has the advantages that: the cooperation of circular fixed mount template and plug-in unit makes the making of bed very convenient, and substantially increase the production efficiency of bed, in bed, the location of each short tube is very accurate; Circular fixed mount template and all plug-in units can constantly be reused, and adopt multiple beds of identical circular fixed mount template construct, effectively can ensure that short tube corresponding in bed is all concentric.

Detailed description of the invention
Below in conjunction with accompanying drawing and preferred embodiment, the utility model is described in further detail.
As Fig. 1, shown in Fig. 2, for making the plate device of bed in fluidized-bed reactor, comprise: circular fixed mount template 1, circular fixed mount template 1 is evenly densely covered with some jacks 2, the distance of adjacent receptacle 2 is identical with the distance of adjacent tubes in bed, plug-in unit 3 is provided with in each jack 2, the structure of each plug-in unit 3 comprises: for the upper intubate 31 of socket joint short tube, the bottom of upper intubate 31 is fixedly connected with lower intubate 32, the external diameter of upper intubate 31 and the internal diameter of bed short tube adapt, and upper intubate 31 closely cooperates with bed short tube, the external diameter of lower intubate 32 and the aperture of jack 2 adapt, and lower intubate 32 closely cooperates with jack 2, upper intubate 31, lower intubate 32 is all concentric with jack 2, lower intubate 32 is inserted in jack 2 until the outer face, bottom of upper intubate 31 is resisted against the surface of circular fixed mount template 1.In this example, in each plug-in unit 3, bottom upper intubate 31, the surface of outer face and circular fixed mount template 1 is all horizontally disposed with.In addition, for the ease of being separated by the jack 2 of plug-in unit 3 with circular fixed mount template 1, the bottom port outer wall of the lower intubate 32 of each plug-in unit 3 is formed slopely groove, is convenient to the demoulding like this.
Operation principle is as follows: according to the size of bed in fluidized-bed reactor, in the circular fixed mount template 1 of horizontal positioned appropriate location jack 2 in insert plug-in unit 3 respectively, the outer face, bottom of the upper intubate 31 of plug-in unit 3 is kept out on the surface of circular fixed mount template 1, then in the upper intubate 31 of the plug-in unit 3 of circular fixed mount template 1, short tube is plugged successively, the bottom end face of short tube is inserted on the surface of circular fixed mount template 1, so just can ensure that the bottom of all short tubes flushes; And then connecting plate is welded to successively between every two adjacent short tubes, because all short tubes are all arranged in upper intubate 31, upper intubate 31 pairs of short tubes play the effect of location on the one hand, also play the effect of constraint short tube on the other hand, prevent short tube from causing displacement because of the welding stress of connecting plate welding generation.The cooperation of circular fixed mount template 1 and plug-in unit 3 makes the making of bed very convenient, and substantially increase the production efficiency of bed, in bed, the location of each short tube is very accurate.After a bed makes, departed from jack 2 respectively by all plug-in units 3 knocked bottom by bed, thus make whole bed shift out circular fixed mount template 1, and then be separated with short tube by the plug-in unit 3 knocked bottom by bed.Circular fixed mount template 1 and all plug-in units 3 can constantly be reused, and adopt identical circular fixed mount template 1 and short tube corresponding in the multiple beds produced in the manner described above is all concentric.
