Description

Technical Field

[0001] This utility model relates to the field of oil and gas purification technology, and in particular to a manhole protection device for a horizontal catalyst reactor. Background Technology

[0002] Hydrogen sulfide in natural gas is converted into sulfur through the Claus sulfur recovery process. In the Claus sulfur recovery process, hydrogen sulfide and sulfur dioxide produce sulfur in a catalytic reactor. The catalytic reaction relies on the catalytic reactor. Horizontal catalytic reactors are usually used to produce sulfur. To fill the catalytic reactor with materials such as catalysts and ceramic balls, and to maintain the horizontal catalytic reactor, a manhole is provided at the top of the horizontal catalytic reactor. The manhole is connected to a flange for connecting blind plates. A grid plate support platform is built on top of the horizontal catalytic reactor to facilitate personnel operations.

[0003] To facilitate catalyst loading and the opening and sealing of manholes, the support platform is positioned above the manhole of the catalytic reactor with an opening. Currently, to prevent personnel from easily stepping into the opening of the grid plate during inspections, a cover is installed at the manhole. However, the cover is not easy to open when the manhole needs to be operated, requiring multiple people to operate. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies, such as the difficulty in opening the manhole cover of a horizontal catalyst reactor, and to provide a manhole protection device for a horizontal catalyst reactor.

[0005] This utility model provides a manhole protection device for a horizontal catalyst reactor, comprising:

[0006] A frame structure component for connecting a support platform, the frame structure component having a cover plate and a vertical guide rail, the cover plate being slidably connected to the guide rail;

[0007] The guide rail is provided with a limiting component, which can be engaged and connected with the cover plate.

[0008] The cover plate is equipped with a driving component, which is connected to the guide rail.

[0009] This utility model discloses a manhole protection device for a horizontal catalyst reactor. A frame structure is connected and fixed to a support platform, ensuring a secure connection between the frame structure and the support platform. A cover plate is placed over the manhole of the horizontal catalyst reactor to shield it, filling any gaps in the grid support platform to prevent personnel from falling. The height of the cover plate can be adjusted by sliding it on a guide rail, and a limiting component can fix the cover plate at a specified height, facilitating the feeding of materials into the manhole and maintenance of the catalyst reactor. A drive component connected to the guide rail allows the cover plate to move along the guide rail, enabling operators to quickly open or close the cover plate for easy operation.

[0010] Preferably, the frame structure has a channel, and both the guide rail and the cover plate are located within the channel.

[0011] The frame structure surrounds the open space supporting the platform, blocking workers and preventing them from stepping into the open space.

[0012] Preferably, a control box is provided on the guide rail, and the control box is connected to the drive component for control.

[0013] The control box controls the movement of the drive components, thereby controlling the relative position of the cover plate and the guide rail, and adjusting the height of the cover plate.

[0014] Preferably, the control box is provided with at least two control buttons.

[0015] The two buttons on the control box control the raising and lowering of the cover, respectively.

[0016] Preferably, the cover plate is provided with a slider, the guide rail is provided with a groove, the slider is adapted to the groove, and the driving component is connected to the slider.

[0017] The slider and the slide groove work together to guide and limit the slider, so that the slider can only slide within the slide groove, allowing the height of the cover plate to be adjusted and ensuring a firm connection between the guide rail and the slider.

[0018] Preferably, the guide rail has a through first limiting hole and a through second limiting hole, the first limiting hole being located on the bottom side of the guide rail and the second limiting hole being located on the top side of the guide rail, the slider having a through third limiting hole, and the limiting member including a rod; the rod can pass through the first limiting hole and the third limiting hole, or the rod can pass through the second limiting hole and the third limiting hole.

[0019] By passing the rod through both the third and second limiting holes, the cover plate is fixed to the top of the guide rail, preventing it from interfering with workers' access to the manhole; by passing the rod through both the third and first limiting holes, the cover plate is fixed to the bottom of the guide rail, preventing it from detaching from the manhole.

[0020] Preferably, the slide groove is provided with a rack, the driving component is provided with a gear, and the rack meshes with the gear.

[0021] When the gear meshes with the rack, the drive unit drives the gear to rotate, causing the gear to move on the rack, thereby adjusting the relative position of the cover plate and the guide rail.

[0022] Preferably, the driving component includes a base and a drive motor, the base is connected to the drive motor, the gear is connected to the drive motor, and the base is connected to the slider.

[0023] The drive motor rotates the gear, changing the connection position between the gear and the rack, thereby adjusting the height of the cover plate.

[0024] Preferably, the top and bottom ends of the guide rail are respectively provided with limiting plates.

[0025] The cover plate is limited by a limiting plate to prevent it from detaching from both ends of the guide rail.

[0026] Preferably, the bottom of the cover plate is provided with a groove that matches the shape of the manhole flange.

[0027] The manhole is equipped with a flange. By embedding the flange into the groove, the flange is positioned to limit the cover plate and prevent the cover plate from detaching from the manhole.

However, it should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0041] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of this utility model is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is typically placed during use.
