When, on tube sheet can stacking material, skewness, bottom blanking is not smooth, and temperature causes material to change colour or imitation frosted glass compared with Gao Shihui
Situation, influence heat transfer efficiency and product quality.
Utility model content
The purpose of this utility model is to provide a kind of heat exchanger of anti-solid accumulation, the pore upper end processing on upper perforated plate
It is tapered or spherical, ensure that the adjacent three round intersection points of plane are summit on tube sheet, solve the problems, such as the solid accumulation of upper perforated plate.
To realize the utility model purpose, the technical scheme used for：A kind of heat exchanger of anti-solid accumulation, including down tube
Case, lower perforated plate, shell-side cylinder, heat exchanger tube, upper perforated plate, upper tube box, it is characterised in that lower tube box bottom sets discharging opening, down tube
Upper box part is connected with lower perforated plate；Bearing and expansion joint are set in shell-side cylinder and open up cold and hot medium import and export adapter and, it is described
Pore corresponding with heat exchanger tube is equipped with upper perforated plate and lower perforated plate, heat exchanger tube is connected by intensity weldering with lower perforated plate and upper perforated plate
Connect；Blocking cylinder is provided between upper tube lower box part and upper perforated plate charging aperture is set as transition, upper tube box top.
Further, the processing of upper perforated plate pore upper end is tapered or spherical, ensure on tube sheet plane it is adjacent three it is round
Intersection point is peak, eliminates the platform between pore.
Further, upper perforated plate and heat exchanger tube junction rounding off.
Further, it is columnar structured to be that pyramidal structure or taper add for the blocking cylinder.
Further, expansion joint is set in shell-side cylinder.
The beneficial effects of the utility model are, using heat exchanger provided by the utility model, solid material to be effectively ensured
In the smooth of tube side passage flow, be not in the situation of solid accumulation, material is evenly distributed, improve heat transfer effect, protect
Product quality is demonstrate,proved, on the other hand, the connection stress of exchanger tubes and tubesheets is small, improves the service life of equipment.
Brief description of the drawings

Fig. 2 is the partial sectional view of upper perforated plate；
Fig. 3 is the partial sectional view of upper perforated plate（Another welding manner of heat exchanger tube）.
Embodiment
The utility model is described in further detail below by specific examples of the implementation and with reference to accompanying drawing.
Fig. 1 shows the heat exchanger of anti-solid accumulation provided by the utility model, including lower tube box 2, lower perforated plate 3, shell side
Cylinder 5, heat exchanger tube 6, upper perforated plate 11, upper tube box 13, the bottom of lower tube box 2 set discharging opening 1, and the top of lower tube box 2 connects with lower perforated plate 3
Connect；Bearing 8 and expansion joint 9 are set in shell-side cylinder 5 and open up cold and hot medium import and export adapter 4 and 10, inside shell-side cylinder 5
Along the length direction of heat exchanger tube 6, deflection plate is set；Heat exchanger tube 6 is welded by intensity and is connected with lower perforated plate 3 and upper perforated plate 11；Upper tube box 13
Bottom sets blocking cylinder 12 close to the position of upper perforated plate 11, and the top of upper tube box 13 sets charging aperture 14.
Fig. 2 and Fig. 3 respectively illustrates two kinds of connected modes, two kinds of different connections between heating tube 6 and upper perforated plate 11
Mode.
The pore upper end of upper perforated plate 11 processes tapered or spherical, the changeover portion 15 between upper perforated plate 11 and heat exchanger tube 6
A smooth transition is formed, ensures that the adjacent three round intersection points 16 of plane are summit on upper perforated plate 11, eliminate pore and pore
Between platform.
The bottom of upper tube box 13 sets blocking cylinder close to the position of upper perforated plate 11（12）, blocking cylinder 12 is pyramidal structure or taper
Add columnar structured, half cone-apex angle A of taper is less than the angle of repose of solid material, and the conelet internal diameter of taper is just upper perforated plate 11
Peripheral platform separates outside.
Expansion joint is set in shell-side cylinder 5（9）.
The cylinder of lower tube box 2 uses pyramidal structure, and half cone-apex angle D of taper is less than the angle of repose of solid material.
Solid material continuously enters upper tube box 13 from charging aperture 14, enters heat exchanger tube 6 by upper perforated plate 11, then pass through down tube
Case 2 discharges from discharging opening 1；Cold and hot medium enters in shell-side cylinder 5 from cold heat medium inlet 4 simultaneously, is drawn by deflection plate 7
Long flow, heat exchange efficiency is improved, is finally gone out from cold heat media outlet pipe 10, the whole heat exchange of solid material and cold and hot medium
Process is completed inside and outside heat exchanger tube 6, reaches the effect dried or cooled down.Because the upper plane of upper perforated plate 11 does not have platform, backgauge
Cylinder 12 again shelters from the platform of the surrounding of upper perforated plate 11, and solid material can pass through upper perforated plate 11 and enter heat exchanger tube 6, without
It can be deposited on tube sheet, avoid causing solid material the discoloration even phenomenon of imitation frosted glass, ensure that product quality, while lower tube box 2
Design it is tapered, and ensure semi-cone angle C be less than solid material angle of repose, enable dry or cool down after material smoothly go out
Material, does not interfere with the heat exchange of epimere material.On the other hand, it is hot swollen due to heat exchanger tube 6 and shell-side cylinder 5 in heat transfer process
Bulk is inconsistent, and difference portion is compensated by expansion joint 9, and reduce heat exchanger tube 6 and upper perforated plate 11 and the weld of lower perforated plate 3 should
Power, improve the service life of equipment.Drying or cooling for solid material provide a kind of preferable heat transmission equipment.
Preferred embodiment of the present utility model is the foregoing is only, is not limited to the utility model, for this
For the technical staff in field, there can be various modifications and variations in the spirit and principles of the utility model, these are equivalent
Modification or replacement etc., are all contained within the scope of protection of the utility model.
