Description

Technical Field

[0001] The utility model relates to the technical field of continuous sewage discharge expansion containers, in particular to a continuous sewage discharge expansion container. Background Art

[0002] The existing continuous sewage expansion tank is also called a continuous sewage expander, which is connected to the continuous sewage outlet of the boiler. It is used to reduce the pressure and expand the capacity of the boiler's continuous sewage. The sewage is adiabatically expanded in the continuous sewage expander to separate into secondary steam and waste hot water, and is expanded, reduced in pressure, and heat exchanged in the expander before being discharged. The secondary steam is led out by a special pipeline, and the waste hot water is automatically discharged through a float liquid level valve or an overflow regulating valve. The heat energy can be recovered and reused. The continuous sewage volume is automatically adjusted as the boiler feed water load changes to maintain a relatively stable sewage discharge rate.

[0003] The manhole is an opening on the continuous sewage expansion tank for personnel to enter or perform inspection, maintenance and other operations. When the continuous sewage expansion tank is working, the manhole cover is connected to the connecting flange of the continuous sewage expansion tank by bolts to close the manhole. During installation, the holes opened in the manhole cover need to correspond to the openings opened in the connecting flange so that the two can be connected by bolts. However, since the manhole cover is usually heavy, the installation work becomes more difficult. Utility Model Content

At this time, rotate the limit screw 7 to make the limit screw 7 fit tightly against the outside of the installation shaft 5. At this time, the installation shaft 5 is fixed, and the manhole cover is fixed. At this time, the staff can use bolts and nuts to connect the manhole cover to the connecting flange. During the connection process, the weight of the manhole cover does not affect the staff's operation. At the same time, the position of the manhole cover is fixed, and the staff will not move at will when using bolts and nuts to connect the manhole cover to the connecting flange, thereby reducing the difficulty of work and improving installation efficiency.

[0025] The outside of the support plate 2 is provided with a groove 8, and the inside of the groove 8 is rotatably connected with a plurality of rotating shafts 9. The rotating shaft 9 consists of three cylinders, and two identical cylinders are fixedly mounted at both ends of a cylinder. The plurality of rotating shafts 9 are located on the upper surface of the support plate 2, which is convenient for the staff to operate the manhole cover to move on the support plate 2. The outside of the support plate 2 is fixedly installed with a limit plate 10. The limit plate 10 is located on the upper surface of the support plate 2 to limit the range of movement of the manhole cover. The outside of the support plate 2 is fixedly installed with a rotating shaft 11, which consists of two The mounting plate 3 is composed of different cylinders, and a rotating hole 12 is opened on the outside of the mounting plate 3. The mounting plate 3 is rotatably connected to the outside of the rotating shaft 11 through the rotating hole 12. When the manhole cover is installed, the mounting plate 3 is rotated downward until the mounting plate 3 is upright. At this time, the mounting shaft 5 is inserted into the inside of the mounting hole 4 again. At this time, the limiting screw 7 is rotated so that the limiting screw 7 fits tightly on the outside of the mounting shaft 5 to fix the mounting shaft 5. At this time, the mounting shaft 5 is below the support plate 2. At this time, the mounting shaft 5 is stored, and the probability of the mounting shaft 5 being damaged due to excessive protrusion is reduced.

[0026] A storage box 13 is provided on the lower surface of the support plate 2, and short plates 14 are fixedly installed at both ends of the storage box 13.

[0027] Working principle:

[0028] After that, the limiting screw 7 is rotated so that the limiting screw 7 is no longer tightly fitted with the outer portion of the installation shaft 5. At this time, the installation shaft 5 is pulled to release the connection between the installation shaft 5 and the manhole cover and the connecting flange, and the last bolt is installed.

[0029] In the second step, after the manhole cover is connected to the connecting flange, the mounting plate 3 is rotated downward until the mounting plate 3 is upright. At this time, the mounting shaft 5 is inserted into the interior of the mounting hole 4 again. At this time, the limiting screw 7 is rotated so that the limiting screw 7 fits tightly against the outside of the mounting shaft 5 to fix the mounting shaft 5.
