[0002] MTO refers to a process technology that uses methanol synthesized from coal or natural gas as raw material and employs a fluidized bed reaction similar to a catalytic cracking unit to primarily produce ethylene. The products of the MTO reaction are ethylene, propylene, and a small amount of n-butene.

[0003] According to the MTO device water-ethanol ratio MTO reaction testing device disclosed in announcement number CN216082634U, which relates to the field of chemical technology, it includes a reaction vessel. The top of the reaction vessel is equipped with a cover plate, and storage tanks are fixedly connected to both ends of the upper surface of the cover plate. A feed pipe is fixedly connected to the bottom of the storage tank, and the bottom end of the feed pipe extends to the bottom of the cover plate. A movable rod is provided on the cover plate, and a turntable is fixedly connected to the bottom end of the movable rod. This utility model sets up two storage tanks, which are used to store methanol and catalyst respectively. By setting up a turntable and a feed pipe, the injection ratio of methanol and catalyst can be adjusted by adjusting the feed hole corresponding to the feed pipe, thus avoiding the waste of time when manually injecting methanol and catalyst each time. By setting up a screw and a screen, solid catalyst can be placed in the screen. By adjusting the position of the screen, the contact time between the catalyst and the reaction solution can be controlled, thereby controlling the reaction.

[0004] The aforementioned device, by setting up a storage tank, can add methanol and catalyst in proportion, making it practical. As shown in the attached diagram, the device can control the contact time between the catalyst and the reaction solution by adjusting the position of the screen through the threaded groove and screw. However, the distance is manually adjusted by the operator during repeated reaction tests. Manually adjusting the distance of the screen is laborious and cumbersome to use. Utility Model Content

[0005] The purpose of this invention is to address the problem that the aforementioned device, which uses a storage tank to add methanol and catalyst in proportion and has a certain degree of usability, is difficult to use due to the fact that, according to the attached drawings, the contact time between the catalyst and the reaction solution can be controlled by adjusting the position of the screen through the threaded groove and screw. Furthermore, the manual adjustment of the screen distance by the operator during repeated reaction tests is laborious and cumbersome. Therefore, this invention provides a water-ethanol ratio MTO reaction testing device for MTO devices.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an MTO device for water-alcohol comparison MTO reaction testing, comprising a reaction vessel body, a vessel lid at the top of the reaction vessel body, and symmetrically arranged storage boxes at the top of the vessel lid. An adjustment assembly is provided at the top of the vessel lid, comprising an adjustment slider slidably connected to the top of the vessel lid, a screen box disposed inside the reaction vessel body, and a mounting block fixedly installed at one end of the adjustment slider.

A support base is fixedly installed at the top of the vessel lid, and a drive arm is rotatably connected to the top of the support base. A rotating shaft is fixedly installed at one end of the drive arm. A support rod is fixedly installed at the top of the vessel lid, and a rotating motor is fixedly installed at the top of the support rod. An eccentric wheel that drives the rotating shaft is rotatably connected to one end of the rotating motor. A sliding block is slidably connected to one end of the drive arm and the side opposite to the rotating shaft, and a connecting arm rotatably connected to the mounting block is rotatably connected to one end of the sliding block.

[0007] As a further embodiment of this utility model: one end of the drive arm is provided with a sliding groove for the sliding block to slide, and a threaded rod that is threadedly connected to the sliding block is rotatably connected inside the sliding groove.

[0010] As a further improvement of this utility model: the bottom end of the reactor body is uniformly and symmetrically fixed with support rods for support, and the bottom end of the reactor body is provided with a discharge pipe.

[0011] As a further improvement of this utility model, an observation window is provided at one end of the reactor body for staff to observe.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this invention, the height of the screen box inside the reactor body can be automatically adjusted by the adjustment component, reducing the labor and time-consuming manual adjustment by the staff.

[0014] In this invention, rotating the handle drives the threaded rod to rotate inside the sliding groove. The rotation of the threaded rod causes the sliding block to slide inside the sliding groove. When the sliding block slides away from the rotating handle, the lifting stroke of the adjusting slider decreases. When the sliding block slides closer to the rotating handle, the lifting stroke of the adjusting slider increases. By adjusting the position of the sliding block inside the sliding groove, the lifting height of the screen box inside the reactor body can be conveniently adjusted. Attached Figure Description

The embodiments of this utility model will be described below based on its overall structure.

[0023] Reference Figures 1 to 5 In this embodiment of the present invention, an MTO device for water-alcohol comparison MTO reaction testing includes a reaction vessel body 1, a vessel lid 2 at the top of the reaction vessel body 1, and storage boxes 3 symmetrically arranged at the top of the vessel lid 2. An adjustment component 4 is provided at the top of the vessel lid 2, comprising an adjustment slider 41 slidably connected to the top of the vessel lid 2, a screen box 42 disposed inside the reaction vessel body 1, and a mounting block 43 fixedly installed at one end of the adjustment slider 41. The adjustment slider 41 passes through the vessel lid 2 and is fixedly connected to the screen box 42. A support base 44 is fixedly installed, and a drive arm 45 is rotatably connected to the top of the support base 44. A rotating shaft 48 is fixedly installed at one end of the drive arm 45. A support rod 46 is fixedly installed at the top of the lid 2, and a rotating motor 47 is fixedly installed at the top of the support rod 46. An eccentric wheel 49 that drives the rotating shaft 48 is rotatably connected to one end of the rotating motor 47. A sliding block 410 is slidably connected to one end of the drive arm 45 and the side opposite to the rotating shaft 48. A connecting arm 411 that is rotatably connected to the mounting block 43 is rotatably connected to one end of the sliding block 410.

[0024] The above-mentioned scheme is adopted: a straight groove adapted to the adjusting slider 41 is opened at the top of the vessel lid 2. The inner wall of the groove is smoothed to reduce the friction when the adjusting slider 41 slides. The adjusting slider 41 is cuboid in shape, and its bottom is embedded in the groove, so that it can slide smoothly in a straight line within the groove. After passing through the through hole opened on the vessel lid 2, the adjusting slider 41 is fixedly connected to the top center of the screen box 42. When the adjusting slider 41 slides at the top of the vessel lid 2, it can drive the screen box 42 to move synchronously inside the reactor body 1.

[0025] Reference Figures 1 to 5 One end of the drive arm 45 is provided with a sliding groove 412 for the sliding block 410 to slide, and a threaded rod 413 that is threadedly connected to the sliding block 410 is rotatably connected inside the sliding groove 412. The threaded rod 413 passes through the sliding groove 412 and a rotating handle 414 is fixedly installed on the outside of the drive arm 45.

[0026] Using the above solution: the rotation of the threaded rod 413 will cause the sliding block 410 to slide inside the sliding groove 412. When the sliding block 410 slides to the side away from the rotating handle 414, the lifting stroke of the adjusting slider 41 will decrease. When the sliding block 410 slides to the side close to the rotating handle 414, the lifting stroke of the adjusting slider 41 will increase. By adjusting the position of the sliding block 410 inside the sliding groove 412, the lifting height of the screen box 42 inside the reactor body 1 can be adjusted conveniently.

[0027] Reference Figures 1 to 5 Support blocks 8 are fixedly installed around the outer periphery of the reactor body 1. The support blocks 8 are evenly and fixedly installed around the outer periphery of the reactor body 1. A hydraulic rod 9 is fixedly installed at the top of the support block 8 and fixedly installed at the bottom of the reactor cover 2. Support bottom rods 7 are evenly and symmetrically fixedly installed at the bottom of the reactor body 1 for support. A discharge pipe 6 is provided at the bottom of the reactor body 1. An observation window 5 is provided at one end of the reactor body 1 for staff to observe.

[0028] The working principle of this utility model is as follows: During the reaction, the screw rod 413 is first rotated inside the sliding groove 412 by rotating the handle 414. The rotation of the screw rod 413 causes the sliding block 410 to slide inside the sliding groove 412. When the sliding block 410 slides away from the handle 414, the lifting stroke of the adjusting slider 41 decreases; when the sliding block 410 slides closer to the handle 414, the lifting stroke of the adjusting slider 41 increases. By adjusting the position of the sliding block 410 inside the sliding groove 412, the lifting height of the screen box 42 inside the reactor body 1 can be conveniently adjusted. Then, the operator starts the rotating motor 47. The output shaft of the rotating motor 47 is fixedly installed with the eccentric wheel 49. When the rotating motor 47 starts working, it drives the eccentric wheel 49 to rotate as well. When the eccentric wheel 49 rotates, it drives the rotating shaft 48 on one side of the drive arm 45 to move inside the eccentric wheel 49, thereby driving the drive arm 45 to swing around the support seat 44 as the origin. When the drive arm 45 swings, the connecting arm 411 at one end of the sliding block 410 and the mounting block 43 at one end of the adjusting slider 41 can drive the adjusting slider 41 to rise and fall inside the reactor body 1. When the operator observes through the observation window 5 that the screen box 42 has reached the specified height, the rotating motor 47 can be stopped. The height of the screen box 42 inside the reactor body 1 can be automatically adjusted by the adjusting component 4, reducing the labor and time-consuming situation of manual adjustment by the operator.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
