[0002] COS hydrolysis catalyst is a chemical substance, and its main function is to convert harmful sulfur compounds such as COS into harmless carbon dioxide and hydrogen sulfide to reduce pollution to the environment. The COS hydrolysis catalyst preparation device usually includes a stirring device, a temperature control device and a filtering device, wherein the filtering device is used to separate solid particles from liquid or gas to obtain the desired product, thereby improving the efficiency of the preparation device.

[0003] In the process of preparing COS hydrolysis catalyst at room temperature, a spherical catalyst structure is usually selected.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1

[0024] like Figure 1-Figure 3As shown, the utility model provides a preparation device of a room temperature COS hydrolysis catalyst, comprising a reactor 1, a rotating assembly 2 and a conversion assembly 3, wherein the top of the reactor 1 is respectively provided with a solid inlet end 12 and a liquid inlet end 13 from front to back, for adding solid and liquid raw materials into the reactor 1, a stirrer 14 is installed inside the reactor 1, and the stirrer 14 is electrically connected through an external terminal for mixing reaction materials, a discharge port 15 is installed at the bottom of the reactor 1, an electronic valve is installed on the discharge port 15 for controlling the discharge of products, a filter box 16 is installed below the discharge port 15, and an annular filter plate 161 is arranged in the filter box 16 for separating solid products The filter box 16 is a spherical structure with openings at the top and bottom. The opening at the top of the filter box 16 corresponds to the discharge port 15. The opening at the bottom of the filter box 16 is rotatably connected to the bottom plate 162. The filter box 16 is equipped with an electronic switch for driving the bottom plate 162 to switch on and off.

[0025] When it is necessary to discharge the product, the electronic valve is controlled to open, and the product flows from the reactor 1 into the filter box 16. By starting the rotating motor 21, the small gear 23 drives the large gear 22 to rotate, and then the annular filter plate 161 rotates inside the filter box 16. Due to the action of centrifugal force, the liquid part is filtered out through the annular filter plate 161, and the solid part remains on the annular filter plate 161. The bottom plate 162 is opened by the electronic switch to collect the product on the bottom plate 162. By setting a spherical structure, the spherical product can be easily rolled inside the filter box 16 to improve the filtering effect of the solid product. At the same time, the spherical product can be accumulated on the bottom plate 162, which is convenient for its collection later and improves the collection effect. The utility model makes it easier to collect the spherical catalyst during the filtering operation through the setting of the spherical structure and the bottom plate 162, which can improve the recovery rate of the solid product and reduce resource waste.

[0026] like Figure 4 As shown, the top of the bottom plate 162 is a circular protrusion structure, and the middle of the bottom plate 162 is provided with filtering holes in a circular array.

[0027] The circular protrusion structure can generate an eddy or vortex effect when the product passes through the filter hole, thereby enhancing the solid-liquid separation effect, and when the bottom plate 162 is opened, the spherical product can be discharged better.

[0028] like Figure 2 and Figure 5 As shown, a discharge box 211 is installed between the bottom of the filter box 16 and the top of the container box 17. A conical hole is opened in the discharge box 211, and a vibration ring 212 is installed in the conical hole. The vibration ring 212 is installed with convex parts 2121 in a ring array.

[0029] When the bottom plate 162 is opened, the bottom plate 162 will contact the vibration ring 212. When the annular filter plate 161 rotates, the bottom plate 162 will continuously impact the ring-shaped convex part 2121. Such vibration and impact will push and disturb the products in the gap, making it easier to be discharged into the discharge box 211, which helps to improve the collection efficiency of the products and reduce the possibility of the products remaining inside the filter.

[0030] Embodiment 2

[0031] like Figure 2 As shown, the conversion assembly 3 is arranged inside the container box 17, and is used to dock the solid discharge port 18 at the bottom of the filter box 16. The conversion assembly 3 includes a telescopic rod 31 installed on the top of the inner side of the container box 17, and a docking tube 32 is installed at the movable end of the telescopic rod 31. A hose 33 is installed between the bottom of the docking tube 32 and the solid discharge port 18. A limit ring 34 is installed on the top of the container box 17. By setting the limit ring 34, it can be used to limit the movement range of the docking tube 32, so as to ensure that the docking tube 32 moves to the correct position and docks with the middle position of the top end of the container box 17.

[0032] When the liquid is completely discharged from the filter box 16, the telescopic rod 31 is started to drive the docking tube 32 to move, so that the docking tube 32 and the middle of the top of the container box 17 are docked. This automatic transition ensures that after the liquid is discharged, the system can automatically enter the solid discharge stage without additional operation or intervention. At this time, the hose 33 enters the pull rope state from the telescopic state, and then the bottom plate 162 is opened to allow the solid product inside the annular filter plate 161 to flow into the solid discharge port 18 through the docking tube 32, and the solid product is collected by the solid discharge port 18. The utility model allows the solid product to flow smoothly into the solid discharge port 18, thereby realizing an automatic and convenient solid discharge process, simplifying the operating process and improving the efficiency of the system.

[0033] The working principle is as follows: the preparation device for room temperature COS hydrolysis catalyst, when it is necessary to discharge the product, by controlling the electronic valve to open, the product flows from the reactor 1 into the filter box 16, by starting the rotating motor 21, the small gear 23 drives the large gear 22 to rotate, and then the annular filter plate 161 rotates inside the filter box 16, due to the action of centrifugal force, the liquid part is filtered out through the annular filter plate 161, and the solid part remains on the annular filter plate 161, when the liquid is completely discharged from the inside of the filter box 16, the bottom plate 162 is opened by the electronic switch, and the telescopic rod 31 is started to drive the butt joint 32 to move, so that the butt joint 32 and the top middle of the container box 17 are butted, this automatic transition ensures that after the liquid is discharged, the system can automatically enter the solid discharge stage without additional operation or intervention, at this time the hose 33 enters the rope pulling state from the telescopic state, and then the bottom plate 162 is opened to allow the solid product inside the annular filter plate 161 to flow into the solid discharge port 18 through the butt joint 32, and the solid product is collected by the solid discharge port 18.

[0034] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
