Description
Technical field
The utility model is related to the components of the tube-type down-flow evaporator equipment of alumina industry, and in particular to a kind of tubular type drop
Film evaporator visor.
Background technology
What is used in alumina industry at present regards ytterbium, has the following disadvantages in use：1, visor periphery easily forms crystallization,
Block visor；2, endoscopy glass is fixed using screw-in bolt, and glass need to be unpicked and washed often, and the screw thread of screw hole is fragile, after damage
Visor replacement must be cut off, it is time-consuming and laborious.
Invention content
The utility model is to solve visor periphery easily to form crystallization and endoscopy glass using screw-in bolt fixing threaded hole
Screw thread it is fragile cause glass to unpick and wash time-consuming and laborious problem, a kind of tube-type down-flow evaporator visor is provided, both can guarantee
Visor side is not easy to crystallize, and the convenient for dismounting and washing endoscopy glass of energy, so that system continuous production is protected, overcomes the prior art not
Foot.
In order to solve the above technical problems, technical solution used by the utility model is：A kind of tube-type down-flow evaporator use
Visor, including Taper Pipe, mounting flange, loose flange and endoscopy glass, the lower end of the mounting flange and the osculum end of Taper Pipe
Welding, the upper end edge centre bore border of mounting flange opens up fluted, the border of the lower end edge centre bore of the loose flange
Open up fluted, cavity of the mounting flange formation opposite with the groove of loose flange for accommodating endoscopy glass, the visor glass
Glass is arranged in the cavity of mounting flange formation opposite with the groove of loose flange；The edge of the mounting flange and loose flange
Place offers corresponding through-hole, the two by stud across corresponding through hole and be screwed into stud both ends nut it is real
The fixation of existing mounting flange and loose flange.
The utility model visor needs to weld the big opening end of Taper Pipe and apparatus casing in specific works, Taper Pipe with it is solid
Determine flange and use certain taper, be welded to connect and be integrated, form horn mouth, resistance is small when medium being made to flow here, flowing
Property is good, is not easy to crystallize, mounting flange offers corresponding through-hole with the edge of loose flange, and the two passes through stud and nut
It is connected and fixed, not only can guarantee that endoscopy glass is unpicked and washed conveniently, but also the inconvenience brought after the screw thread in former screw hole is damaged can be solved, it can
To shorten the repair time, efficiency is improved.
The utility model has the advantages that compared with prior art：
Taper Pipe is connect by the utility model with mounting flange, forms horn mouth, and making medium, flow resistance is small here, flowing
Property it is good, be not easy to crystallize, original screw-in screw hole be changed to through-hole, not only can guarantee that endoscopy glass is unpicked and washed conveniently, but also can solve spiral shell
The inconvenience that silk in hole is brought after being damaged can shorten the repair time, improve efficiency, and maintenance expense is low, continuous production is good.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model tube-type down-flow evaporator visor.
It is marked in figure as follows：
1- Taper Pipes, 2- mounting flanges, 3- endoscopy glass, 4- loose flanges, 5- nuts, 6- studs, 7- gaskets.
Specific implementation mode
Below in conjunction with specific embodiment, the utility model is described in further detail.
Embodiment 1
As shown in Figure 1, a kind of tube-type down-flow evaporator visor, including Taper Pipe 1, mounting flange 2, loose flange 4 and
Endoscopy glass 3, the lower end of the mounting flange 2 are welded with the osculum end of Taper Pipe 1, and Taper Pipe uses certain cone with mounting flange
Degree, is welded to connect and is integrated, and forms horn mouth, resistance is small when medium being made to flow here, good fluidity, is not easy to crystallize.It is fixed
The upper end edge centre bore border of flange 2 opens up fluted, and the border of the lower end edge centre bore of the loose flange 4 also offers recessed
Slot, cavity of the formation opposite with the groove of loose flange 4 of mounting flange 2 for accommodating endoscopy glass 3, the endoscopy glass 3 are set
It sets in the cavity of the formation opposite with the groove of loose flange 4 of mounting flange 2；The edge of the mounting flange 2 and loose flange 4
Place offers corresponding through-hole, and the two is by stud 6 across corresponding through hole and is screwed into the nut at 6 both ends of stud
5 realize the fixation of mounting flange 2 and loose flange 4.
The position that the endoscopy glass 3 is in contact with mounting flange 2 and loose flange 4 is additionally provided with the gasket 7 of annular.Pad
Piece 7 mainly seals, and medium is made not leak out, and secondly visor can be protected to be not easy damaged.
As shown in Figure 1, the section top of the centre bore of loose flange 4 is inverted trapezoidal, lower part is rectangle.In loose flange 4
The flaring in heart hole designs, and can increase angular field of view, convenient for the fluid media (medium) in staff's observation device.
The section of the centre bore of the mounting flange 2 is trapezoidal.What the central division cone of mounting flange 2 was welded with its lower end
Taper Pipe 1 is consistent.
