Description

Technical Field

[0001] The invention relates to the technical field of gas cabinet bell balancing, and in particular to a vertical lift wet gas cabinet gas storage pressure setting and bell balancing device. Background Art

[0002] Gasholders are used to store various industrial gases and are also used to balance the unevenness of gas demand. Wet gasholders are the simplest and most common type of gasholders. Usually used for coal gas storage, they consist of a water seal tank and a bell jar.

[0003] The wet gas tank is a fully welded steel structure with a cylindrical tall structure and a large diameter. During operation, the bell cover is required to be raised and lowered relatively smoothly without jamming or friction. The bell cover relies on the guide rail fixed on the inside of the water tank and the guide frame track outside the water tank to slide with the external guide wheel installed on the bell cover, and slowly rise or fall. The external guide frame type vertical gas tank only detects the pressure, water level, cabinet capacity and cabinet speed, and does not perform intelligent adjustment and setting of the cabinet capacity pressure, the inclination of the bell cover and the stress of the guide wheel. Low-pressure wet gas tanks do not allow overpressure or negative pressure, or excessive inclination. Excessive inclination not only cannot guarantee the gas sealing requirements, but also causes severe wear of the guide wheel and guide frame, resulting in failure of the bell cover to rise and fall, causing safety accidents.

[0020] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0021] Combination Figure 1 and Figure 2 As shown, a vertical-lift wet gas holder gas storage pressure setting and bell jar balancing device includes a fixing member 6, the cross-sectional shape of the fixing member 6 is similar to an I-beam or an H-beam, and a receiving groove 12 is provided on the upper and lower parts of the front of the fixing member 6. A pressure sensor 11 and a support block 10 are provided inside the receiving groove 12. The pressure sensor 11 and the support block 10 are placed front and back. The support block 10 is subjected to a horizontal force acting on the pressure sensor 11. The horizontal force on the support block 10 can be obtained in real time through the pressure sensor 11. This device is installed on the side wall of the bell jar, and the number of installations is not unique, which plays a role in supporting the side wall of the bell jar, that is, the pressure sensor 11 is used to monitor the radial force of the bell jar. At the same time, two pressure sensors 11 are provided in each device, and the radial resultant force of the two pressure sensors 11 is the radial force received by the device.

[0022] A support rod 9 is rotatably connected to the support block 10 located at the upper part, a convex plate is arranged on the front side of the support block 10, and a rotating shaft inserted through the end of the support rod 9 is rotatably fitted on the convex plate, and the other end of the support rod 9 is rotatably connected to a connecting piece 2, the connecting piece 2 is composed of three plates and forms the shape of a channel steel, one side of the connecting piece 2 is rotatably connected to a guide wheel 1, and the guide wheel 1 is rollingly fitted on a guide rail arranged on the outside of the bell jar, and during the process of lifting and lowering the bell jar, the guide wheel 1 is fixed on the guide rail to ensure that the bell jar rises or falls smoothly.

[0023] The support block 10 at the bottom is rotatably connected with an electric cylinder 4. The connection mode of the end of the electric cylinder 4 is consistent with that of the support rod 9. The other end of the electric cylinder 4 is extended with a telescopic rod 3. The other end of the telescopic rod 3 is rotatably connected with the support rod 9. Specifically, the end of the telescopic rod 3 is fixedly connected with a U-shaped piece. The U-shaped piece is held on the side wall of the support rod 9 and is interspersed with a rotating shaft. At this time, the support rod 9, the electric cylinder 4 and the telescopic rod 3 constitute a structure supporting the guide wheel 1. When the electric cylinder 4 is started, the telescopic rod 3 extends or retracts to push and pull the support rod 7, thereby changing the distance between the guide wheel 1 and the bell cover. If the bell cover is tilted, the electric cylinders 4 on each device are linked to control the bell cover to straighten it.

[0024] Furthermore, the extended length of the telescopic rod 3 can be obtained, that is, the type selected by the electric cylinder 4 has this function, and the position of the support block 10 and the length of the support rod 9 will not change when the electric cylinder 4 is in action, that is, by obtaining the distance between the two support blocks 10 and the length of the support rod 9 in advance, and cooperating with the length change information of the telescopic rod 3, the spacing between the guide wheel 1 and the bell cover can be calculated, and the calculation data of each device can be combined to obtain the axial position of the bell cover, and then the deviation distance and deviation direction of the center of the bell cover can be obtained, and the electric cylinder 4 can be linked again to adjust the position of the bell cover.

[0025] Furthermore, since the mass of the bell housing is large, the electric cylinder 4 requires a large thrust, and a multi-stage planetary reduction mechanism can be added to the electric cylinder 4, or the electric cylinder 4 can be replaced by a hydraulic cylinder, but an external hydraulic source is required.

[0026] The front of the fixing member 6 is fixedly connected with an inclination sensor 8 for monitoring whether the bell jar is tilted.
