Description
Technical Field
The utility model relates to a sealed lid operating means field of small-size pressure vessel, concretely relates to light-duty hydrogen filter flange cover auxiliary opening device.
Background
With the continuous deepening of the utilization of hydrogen energy in the chemical industry, the filter is more and more applied to the fields of hydrogen energy utilization and gas power generation, in particular to the field of gas-liquid separation of gas power generation. However, when the filter element needs to be replaced after the filter operates for a period of time, the flange cover needs to be opened, and for a light filter with a small diameter, the flange cover is light and can be lifted by an operator with a handle, but the operation is still laborious after repeated operation, and the residual hydrogen in the filter is combustible and has certain pressure, so that the operation mode is not safe and meets the specification, and safety accidents are easy to happen. The ideal operation mode is that the flange cover of the filter is lifted to a certain height, and the flange cover is rotated to be opened by using the handle after the pressure is completely relieved.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a light-duty hydrogen filter flange cover auxiliary opening device to solve the problem that exists among the background art.
In order to realize the purpose, the technical scheme is as follows:
the utility model provides a light-duty hydrogen filter flange cover auxiliary opening device, includes filter barrel, lifting bolt, nut, bottom suspension fagging, main shaft sleeve, oil filler point stopcock, goes up backup pad, main shaft sleeve gland, main shaft connecting plate, reinforcing plate and handle, be provided with the oil filler point on the main shaft sleeve lateral wall, the main shaft sleeve weld mutually with backup pad and last backup pad and main shaft sleeve gland respectively from supreme down, and the nut welds mutually with the bottom suspension fagging bottom surface, during the use lifting bolt withstands the lower terminal surface of main shaft, the main shaft welds mutually with main shaft connecting plate, reinforcing plate respectively, and main shaft connecting plate and reinforcing plate weld mutually with the flange cover, the handle welding is in the flange cover middle part, and the bottom suspension fagging still welds mutually with the filter barrel with last backup pad.
Compared with the prior art, the beneficial effects of the utility model are that: when the flange cover lifting device is used, the flange cover can be lifted only by rotating the lifting bolt with a wrench, the flange cover lifting device is simple and convenient, time and labor are saved, and the safety is enhanced.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
The labels in the figure are: 1-filter cylinder, 2-lifting bolt, 3-nut, 4-lower support plate, 5-main shaft sleeve, 6-oil hole pipe plug, 7-upper support plate, 8-main shaft, 9-main shaft sleeve gland, 10-main shaft connecting plate, 11-reinforcing plate, 12-flange cover and 13-handle.
Detailed Description
The invention will be further explained and illustrated with reference to the following examples and the accompanying drawings.
Example (b): referring to fig. 1, the auxiliary opening device for the flange cover of the light hydrogen filter comprises a filter cylinder body 1, a lifting bolt 2, a nut 3, a lower supporting plate 4, a spindle sleeve 5, an oil filler pipe plug 6, an upper supporting plate 7, a spindle 8, a spindle sleeve gland 9, a spindle connecting plate 10, a reinforcing plate 11 and a handle 13, wherein the spindle sleeve 5 is provided with the oil filler, the spindle sleeve 5 is welded with the lower supporting plate 4, the upper supporting plate 7 and the spindle sleeve gland 9 from bottom to top respectively, the nut 3 is welded with the bottom surface of the lower supporting plate 4, the lifting bolt 2 ascends along threads to support the lower end surface of the spindle 8 during use, the spindle 8 is welded with the spindle connecting plate 10 and the reinforcing plate 11 respectively, the spindle connecting plate 10 and the reinforcing plate 11 are welded with the flange cover 12, the flange cover 12 slowly ascends while the spindle 8 is ensured to ascend, the lower end surface of the handle 13 is welded with the flange cover 12, and the lower supporting plate 4 and the upper supporting plate 7 are also welded with the filter cylinder body 1.
During installation, the assembly of the main shaft 8 is installed in the assembly of the main shaft sleeve 5, the sealing surface of the flange cover 12 is tightly abutted to the sealing surface of the flange, then the connecting bolt of the flange cover 12 and the flange of the filter is screwed, then the lifting bolt 2 is screwed into the nut 3, a certain gap is reserved between the upper end surface of the lifting bolt 2 and the lower end surface of the main shaft 8, a proper amount of lubricating oil is injected through the oil filling hole, and finally the oil filling hole pipe plug 6 is screwed.
When the filter flange cover lifting device is used, connecting bolts of the filter flange cover 12 and a flange are loosened, the lifting bolts 2 are rotated by a wrench to lift the main shaft 8, the flange cover 12 is connected with the main shaft 8 through the main shaft connecting plate 10 and the reinforcing plate 11, the flange cover 12 is lifted at the same time, and after the flange cover is lifted to a certain height, the flange cover 12 is pulled up together with the flange cover 12 and the rotating main shaft 8 through the handle 13 to open the flange cover 12.
