Description

Technical Field

[0001] This utility model belongs to the field of chemical production safety testing equipment, and in particular relates to a gas detection device in a hydroformylation workshop. Background Technology

[0002] Hydroformylation, also known as carbonyl synthesis, refers to the process by which olefins react with carbon monoxide and hydrogen in the presence of a catalyst to produce aldehydes, which have one more carbon atom than the feed olefins. Hydroformylation is a key process in the production of aldehyde compounds. Hydroformylation workshops involve flammable, explosive, or toxic gases such as carbon monoxide, hydrogen, and olefins, making gas leak detection crucial.

[0003] To improve safety in hydroformylation workshops, CO sensors are installed. Currently, most CO sensors are wall-mounted or recessed into the wall, but their positions lack adjustability. Especially since CO density is slightly greater than air, if the CO sensor remains in its original position when CO concentration increases, the timeliness of its alarm will be greatly reduced, affecting the operational safety of the workshop.

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] Examples, such as Figures 1-4 As shown, the gas detection device for a hydroformylation workshop provided by this utility model includes a CO sensor body 1, with a wire 2 installed on the back of the CO sensor body 1. The wire 2 is connected to a control device for controlling the ventilation system in the workshop. When the concentration detected by the CO sensor body 1 reaches a critical value, the control device can activate the ventilation system and increase the ventilation rate to improve the safety of the workshop's gas atmosphere. Based on this, the CO sensor body 1 provided by this utility model is nested on the wall-mounted box 3. The wall-mounted box 3 includes a box body 31. The top of the box body 31 is provided with a vertical tube 32 that is connected to the box body 31 and used for wiring. The top of the vertical tube 32 is provided with a horizontal hinge cylinder 33. A first folding plate 4 is hinged on the hinge cylinder 33. The interior of the first folding plate 4 is provided with a hollow first wiring plate hole 41 that passes through both ends of the first folding plate 4. A second folding plate 5 is hinged on the end of the first folding plate 4 away from the hinge cylinder 33. The interior of the second folding plate 5 is provided with a hollow second wiring plate hole 51 that passes through both ends of the second folding plate 5. A positioning groove 6 is hinged on the end of the second folding plate 5 away from the second folding plate 5. A top connecting plate 61 and a side connecting plate 62 are respectively provided on the top and sides of the positioning groove 6.

[0018] Specifically, the wall-mounted box 3 and box body 31 provided by this utility model serve as the quick-nesting base for the CO sensor body 1. The wire 2 passes from the back of the CO sensor body 1 from bottom to top through the box body 31, the vertical tube 32, the hinge tube 33, the first wiring board hole 41, the second wiring board hole 51, and the positioning groove 6. The positioning groove 6 is used to establish an installation relationship with the workshop wall through bolts until the wire 2 is connected to the workshop control equipment. The control equipment is also electrically connected to the workshop's exhaust equipment, which facilitates the linkage between CO concentration detection and exhaust, thereby improving the safety of the workshop.

[0019] Furthermore, the vertical tube 32 of the wall-mounted box 3, together with the first folding plate 4, the second folding plate 5, and the positioning groove 6, constitute a folding mechanism with folding function. The detection sites of the CO sensor body 1 are coordinated according to the distribution density of workshop equipment and the volume of work. Using this folding mechanism connected to the workshop wall, it is easy to adjust the actual position of the CO sensor body 1 in space. Especially in workshops with a large volume of work, the height of the CO sensor body 1 can be appropriately lowered to reduce the probability of detection delay caused by excessive CO concentration at low horizontal positions and uneven local distribution. This results in better detection immediacy and improves the safety of the hydroformylation workshop.

[0020] To improve the adjustability of this device, the side of the vertical tube 32 provided by this invention is provided with an E-shaped handle 310, with the E-shaped opening of the handle 310 facing vertically towards the vertical tube 32. The E-shaped feature of the handle 310 makes it easy to hold, facilitating not only hand adjustment to the actual detection height of the device, but also making it convenient to hold the handle 310 to press the wall-mounted box 3 against the workshop wall when disassembling and assembling the CO sensor body 1, while using the other hand to remove the CO sensor body 1 from the box 31.

[0021] Furthermore, the bottom of the CO sensor body 1 provided by this utility model is provided with a pull plate 11, so that two hands can apply opposite forces to the pull plate 11 and the handle 310 respectively, which is beneficial to remove the CO sensor body 1 from the box 31.

[0022] To improve the overall performance of the internal wiring 2 of this device, the housing 31 provided by this invention is provided with two positioning tubes 34 spaced apart from each other. Each positioning tube 34 has a threaded hole 35, and a positioning element 36 is installed within the threaded hole 35. The positioning element 36 includes a threaded post 361, and a circular pressure handle 362 is provided at the end of the threaded post 361. The positioning tubes 34 provide a spaced foundation for the portion of the wiring 2 within the housing 31. The positioning element 36 presses the surface of the wiring 2 between the pressure handle 362 and the inner wall of the housing 31, preventing the wiring 2 from becoming tangled or twisted significantly due to the folding and adjustment operations of this device. This improves the electrical connection reliability of the CO sensor body 1, thereby ensuring the detection performance of this device.

[0023] To improve the reliability of the quick connection between the CO sensor body 1 and the wall-mounted box 3, the CO sensor body 1 provided by this utility model is provided with a U-shaped locking protrusion 12 distributed around its lower half. The locking protrusion 12 and the stepped opening 37 provided on the box body 31 are engaged and matched. Before the CO sensor body 1 is nested with the inner wall of the wall-mounted box 3, the locking protrusion 12 can be attached to the stepped opening 37. As the locking protrusion 12 moves backward along the stepped opening 37, the inner wall of the CO sensor body 1 can gradually enter a tight fit with the box body 31.

[0024] Furthermore, the CO sensor body 1 provided by this utility model has key-type positioning protrusions 13 on both sides, which engage with rectangular holes 38 on both sides of the box 31. Both sides of the CO sensor body 1 have insertion ports 14, which tightly engage with insertion strips 39 on the inner wall of the box 31. The key-type positioning protrusions 13 and rectangular holes 38 form a snap-fit ​​relationship, preventing significant front-to-back nesting deviation between the CO sensor body 1 and the box 31. The insertion ports 14 and insertion strips 39 provide a smaller insertion distance relative to the outer wall of the CO sensor body 1 and the inner wall of the box 31, but increase the insertion area and direction. They also serve as a guide structure before complete insertion, thereby improving the fit quality between the CO sensor body 1 and the wall-mounted box 3.

[0025] To improve the practicality of the hinged cylinder 33, the hinged cylinder 33 provided by this utility model includes a hollow cylinder 331. The side of the cylinder 331 is provided with a side hole 332 corresponding to the first wiring plate hole 41, and the end of the cylinder 331 is provided with a shaft head 333. In addition to their own plate bodies, the first folding plate 4 and the second folding plate 5 have hinge ears for hinged connection and hinge joints with a structure similar to that of the hinged cylinder 33 at their ends. The side of the hinge joint has a wiring plate hole. The shaft head 333 is tightly fitted with the hinge ear, and the shaft structure at the end of the hinge joint is tightly fitted with the hinge ear. Under non-manual operation, the folding angle of the wall-mounted box 3, the first folding plate 4, the second folding plate 5 and the positioning groove 6 will not change arbitrarily, thereby ensuring the adjustability and diversity of the detection points of the CO sensor body 1 in space, which is conducive to improving the utilization rate and applicability of the CO sensor body 1.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
