Description

TECHNICAL FIELD

[0001] The application relates to the technical field of catalyst proportioning equipment, in particular to a quantifiable catalyst proportioning equipment for chemical production. BACKGROUND

[0002] A catalyst is a core element of chemical production. The catalyst can make a reaction that needs high temperature, high pressure or a long time to be completed quickly under a more moderate condition by reducing the activation energy of the reaction. The catalyst can also promote a specific reaction path and inhibit a side reaction, thereby improving the selectivity and purity of a target product. In addition, the catalyst can also improve the reaction condition and ensure production safety. A catalyst proportioning equipment is a core device for preparing the catalyst. The catalyst proportioning equipment directly determines the performance and industrial application effect of the catalyst by accurately controlling the proportioning of raw materials, a mixing process and a reaction condition. A hydroxyl iron desulfurization catalyst is a commonly used catalyst in the chemical field. The catalyst can efficiently remove sulfur pollutants, improve energy cleanliness and optimize an industrial production process. In the preparation process of the hydroxyl iron desulfurization catalyst, raw materials of the hydroxyl iron desulfurization catalyst are proportioned and pretreated. The raw materials of the hydroxyl iron desulfurization catalyst mainly include ferrous sulfate as an iron source, an alkaline hydroxide for adjusting the pH value of a reaction system and other auxiliary components (such as sodium metaaluminate and a complexing agent) for improving the stability or sulfur capacity of the catalyst. After the proportioning is completed, the ferrous sulfate solution and the alkaline hydroxide solution are mixed in proportion, the temperature is controlled in the range of 30-60 DEG C, and sodium aluminate (NaAlO2) and other auxiliary agents are added. The FeOOH crystal form is promoted by complexation, that is, a precursor. Then, air or oxygen is continuously introduced to promote the oxidation of Fe 2+ to Fe 3+ However, in the actual treatment process, the raw materials of the hydroxyl iron catalyst, such as the FeSO4 solution and the NaOH solution, have a certain density difference. Therefore, in the stirring process, a laminar flow state often occurs in the early stage. The laminar flow state affects the particle collision, so that the raw materials in the proportioning and mixing equipment have a density uneven state for a long time. Then, the hydroxyl on the surface of the precursor, that is, the FeOOH particle, forms a hydrogen bond with the sodium ion in the alkaline solution, that is, the particles are cohesively grouped to increase the volume of the precursor and increase the difficulty of the full reaction with oxygen, thereby affecting the quality of the generated catalyst. Therefore, the application provides a quantifiable catalyst proportioning equipment for chemical production. SUMMARY

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0018] Please refer to Figures 1-11The application provides a technical scheme: a quantifiable catalyst proportioning equipment for chemical production, which is improved in the technical problems in the background art. The catalyst proportioning equipment comprises a tank 1 for mixing catalyst raw materials, a metering pump 2 arranged on one side of the tank 1 and used for controlling the addition amount of the catalyst raw materials, a conveying pipeline 3 in communication between the metering pump 2 and the tank 1, a steel support 4 fixedly installed at the bottom of the tank 1, a steel shaft body 41 fixedly installed on the steel support 4, a servo motor 5 fixedly installed at the top of the tank 1, a rotating shaft body 51 fixedly installed at the output end of the servo motor 5 and extending into the tank 1, a plurality of limiting sleeves 52 installed in parallel on the rotating shaft body 51 along the central line direction of the rotating shaft body 51, a connecting shaft body 53 symmetrically installed on each limiting sleeve 52 and rotatably connected with the inner wall of the limiting sleeve 52, and a plurality of stirring parts 6 arranged on each connecting shaft body 53 and capable of changing the angle according to the density of the raw materials. As a further limitation in the present application, in combination with the accompanying Figure 6 and accompanying Figure 7 The stirring part 6 comprises an annular sleeve 61 fixedly installed on the connecting shaft body 53, a plurality of support shaft bodies 62 fixedly installed on the annular sleeve 61, a spherical fitting groove 63 arranged in each support shaft body 62, a spherical connecting part 64 movably connected with the inner wall of the spherical fitting groove 63 and fixedly installed on the spherical connecting part 64, and a stirring blade 65 fixedly installed on the spherical connecting part 64. Since the spherical connecting part 64 is movably connected with the spherical fitting groove 63, the stirring blade 65 is acted on by the raw materials in the tank 1 during movement. When there is a density difference between the raw materials in different regions, the stirring blade 65 is contacted with the raw materials in different regions with different densities during rotation and is adjusted in angle under the action of the raw materials. Since the angle of the stirring blade 65 is related to the density of the raw materials, the stirring blade 65 capable of changing the angle according to the density of the raw materials is used to mix the raw materials, thereby improving the mixing quality of the raw materials. In the early stages of the reaction, to ensure rapid mixing of the raw materials, the rotation speed of the rotating shaft 51 is usually increased. In the later stages of the reaction, to ensure the stability of the mixed raw materials, the rotation speed is usually reduced. Furthermore, to avoid excessive shearing of the FeOOH nanostructure by the stirring blades 65 in the later stages of the reaction, this invention incorporates a spherical connecting part 64 made of magnetic material. The supporting shaft 62 also has a cavity 621 installed inside, and an arc-shaped magnet 622 slidably connected to its inner wall is installed within the cavity 621. The arc-shaped magnet 622 is in contact with the surface of the spherical connecting part 64, and a plastic spring 623 connects the arc-shaped magnet 622 to the inner wall of the cavity 621. When the rotating shaft 51 rotates... When the speed is relatively fast, the arc-shaped magnet 622 will compress the plastic spring 623 under the action of centrifugal force. At this time, the arc-shaped magnet 622 will leave the contact point of the spherical connecting part 64, that is, the arc-shaped magnet 622 will no longer contact the spherical connecting part 64. The spherical connecting part 64 can then make corresponding angle adjustments in the spherical fitting groove 63 according to the raw material density. When the rotation speed of the rotating shaft 51 decreases, the arc-shaped magnet 622 will overcome the influence of centrifugal force under the action of the plastic spring 623. That is, the arc-shaped magnet 622 will contact the spherical connecting part 64 and use friction to hinder the spherical connecting part 64 from making angle adjustments, so that the stirring of the raw materials in the tank 1 tends to be stable. The steel shaft 41 has cavities 411 corresponding to the limiting sleeves 52, and an annular gear rack 412 is fixedly installed in each cavity 411. Each limiting sleeve 52 has a drive shaft 521 rotatably connected to its inner wall. The end of the drive shaft 521 passes through the inner walls of the limiting sleeve 52 and the rotating shaft 51 and extends into the cavity 411. A meshing gear 522 is also fixedly installed at one end of the drive shaft 521 located in the cavity 411. Figure 3 As shown, the meshing gear 522 near the top of the tank 1 has a larger radius and more teeth than the meshing gear 522 near the bottom of the tank 1. Consequently, the rotational speed of the meshing gear 522 near the top of the tank 1 is relatively lower than that of the meshing gear 522 near the bottom of the tank 1. A sliding shaft 523 is installed inside the transmission shaft 521 and is slidably connected to its inner wall. A constant force spring 524 is connected between the sliding shaft 523 and the inner wall of the transmission shaft 521. A circular panel 525 is also fixedly installed at the end of the sliding shaft 523, and multiple matching balls 526 are also fixedly installed on the circular panel 525. One end of the connecting shaft 53 is located inside the limiting sleeve 52. A force-receiving disc 531 is also fixedly installed at the end of the connecting shaft 53 located inside the limiting sleeve 52, and multiple through slots 532 corresponding to the matching balls 526 are opened on the force-receiving disc 531.

[0019] Specifically, in conjunction with the appendix Figure 1As shown, in actual use, the metering pump 2 quantitatively measures the catalyst raw materials participating in the reaction and, under the action of the conveying pipeline 3, conveys the raw materials to the tank 1. During the conveying process to the tank 1, the servo motor 5 starts, and its output end drives the rotating shaft 51 to rotate at the upper limit of the steel shaft 41. During the rotation of the rotating shaft 51, the limiting sleeve 52 on it rotates synchronously with it. During the rotation of the limiting sleeve 52, the transmission shaft 521 connected to it rotates synchronously. During the rotation of the transmission shaft 521, the meshing gear 522 at its end engages with the annular ring. The gear rack 412 meshes and rotates. In the early stage of stirring, the rotational speed of the rotating shaft 51 is relatively high. Consequently, the sliding shaft 523 within the transmission shaft 521 moves outward under the action of centrifugal force. That is, the sliding shaft 523 stretches the constant force spring 524, and the circular panel 525 at the end of the sliding shaft 523 and its multiple matching balls 526 enter the through groove 532. In other words, the multiple matching balls 526 at the end of the sliding shaft 523 enter the through groove 532, thereby driving the force-bearing disk 531 to move around the center line of the sliding shaft 523 as its axis. As the rotating disk 531 rotates, it drives the connecting shaft 53 to rotate synchronously, and consequently, the stirring part 6 on the connecting shaft 53 rotates synchronously with it. To further explain, during the rotation of the meshing gear 522 at the end of the transmission shaft 521 and the annular gear rack 412, the meshing gear 522 near the top of the tank 1 has a larger radius and more teeth than the meshing gear 522 near the bottom of the tank 1. Therefore, the rotational speed of the meshing gear 522 near the bottom of the tank 1 is relatively greater than that of the meshing gear 522 near the top of the tank 1, thus causing the meshing gear 522 near the bottom of the tank 1 to rotate at a higher speed. The connecting shaft 53 rotates at a higher speed than the connecting shaft 53 near the top of the tank 1. Consequently, the stirring blades 65 near the bottom of the tank 1 also rotate at a higher speed than the stirring blades 65 near the top of the tank 1. This creates a speed gradient between the high-speed stirring blades 65 at the bottom and the relatively low-speed stirring blades 65 at the top, driving the material to flow upward from the high-speed zone at the bottom and reducing the sedimentation rate of the precursor. As the connecting shaft 53 drives the supporting shaft 62 to rotate through the annular sleeve 61, the supporting shaft 62, in turn, drives the stirring blades 65 to rotate through the spherical connecting part 64. The stirring blades 65 on the same plane are shown in the attached figure. Figure 5As shown, further, the stirring blade 65 in the process of circumferential movement with the center line of the rotating shaft body 51, the movement track of the stirring blade 65 covers each area in the tank body 1, and the stirring blade 65 is acted on by the raw materials in the rotating process, when the density of the area has a large difference, the stirring blade 65 is acted on by the raw materials and is adjusted in angle, it needs to be explained that when the rotating speed of the rotating shaft body 51 is fast, the arc-shaped magnet 622 is compressed to the plastic spring 623 under the action of centrifugal force, at this time, the arc-shaped magnet 622 is away from the contact of the spherical connecting part 64, that is, the arc-shaped magnet 622 is no longer in contact with the spherical connecting part 64, so that the arc-shaped magnet 622 is no longer in contact with the spherical connecting part 64, and the spherical connecting part 64 can be adjusted in angle in the spherical fitting groove 63 according to the density of the raw materials; in the later stage of the reaction, the rotating speed of the rotating shaft body 51 is usually reduced, and then the sliding shaft body 523 drives the circular panel 525 to reset under the action of the constant force spring 524, and the fitting ball 526 on the circular panel 525 is away from the slot 532, so that the circular panel 525 will not drive the connecting shaft body 53 to rotate, and the arc-shaped magnet 622 will be under the action of the plastic spring 623, so that the arc-shaped magnet 622 overcomes the influence of centrifugal force, that is, the arc-shaped magnet 622 is in contact with the spherical connecting part 64, and the friction force is used to hinder the spherical connecting part 64 to adjust the angle, so that the stirring of the raw materials in the tank body 1 tends to be stable when the rotating speed is low.

[0020] During the mixing process of the catalyst, the generated precursors often adhere to each other to form a large volume of precursors, which increases the difficulty of full reaction with oxygen. Therefore, the present application is designed as follows: the rotating shaft body 51 is also symmetrically provided with a fixed shaft body 7, the fixed shaft body 7 and the connecting shaft body 53 are in contact with the inner wall of the tank body 1 through balls, each fixed shaft body 7 is parallelly provided with a steel frame 71, the top of the steel frame 71 is also fixedly provided with a processing frame 72, the cross section of the feeding end of the processing frame 72 is larger than that of the discharging end, a cutting tool holder 73 is installed inside the processing frame 72, the cutting tool holder 73 is close to the discharging end of the processing frame 72, a magnetic column 74 is also fixedly installed on the cutting tool holder 73, a stress shaft body 75 is rotatably connected with a plurality of steel frames 71 above the fixed shaft body 7, torsional springs 76 are connected between the stress shaft body 75 and the inner walls of the plurality of steel frames 71, two square magnetic plates 77 are fixedly installed in the region of the steel frame 71 where the stress shaft body 75 is located, one of the square magnetic plates 77 is opposite to the magnetic pole of the magnetic column 74, and the other square magnetic plate 77 is the same as the magnetic pole of the magnetic column 74, a stress rod holder 751 is fixedly installed at the end of the stress shaft body 75, a plurality of stress rod holders 8 are fixedly installed on the inner wall of the tank body 1, and the stress rod holders 8 are located on the movement track of the stress rod holder 751.

[0021] Specifically, combined with the accompanying drawings Figure 2 and the accompanying drawings Figure 8 As shown, the rotating shaft body 51 drives the fixed shaft body 7 to rotate synchronously during rotation, and the steel frame 71 and the processing frame 72 on the fixed shaft body 7 move synchronously. During rotation of the processing frame 72 around the rotating shaft body 51, the precursor generated in the tank body 1 enters the processing frame 72 from the large cross-section inlet end and flows out from the small cross-section outlet end. The precursor flowing out from the small cross-section outlet end is the qualified precursor of a certain size, and the relatively large precursor is blocked at the outlet end of the processing frame 72. The force receiving shaft body 75 on the fixed shaft body 7 rotates synchronously during rotation of the fixed shaft body 7. The force receiving rod frame 751 at the end of the force receiving shaft body 75 rotates during rotation and contacts the force applying rod frame 8. It should be noted that when the force receiving shaft body 75 is not rotating, the magnetic pole of the magnetic cylinder 74 located directly above one of the square magnetic plates 77 is opposite to the magnetic pole of the square magnetic plate 77, and the magnetic pole of the other square magnetic plate 77 is the same as that of the magnetic cylinder 74. When the force receiving shaft body 75 rotates, the torsion spring 76 connected between the force receiving shaft body 75 and the inner wall of the steel frame 71 is in a tightened potential state, and the two square magnetic plates 77 on the force receiving shaft body 75 are adjusted in angle. The square magnetic plate 77 originally opposite to the magnetic cylinder 74 moves away from the position directly below the magnetic cylinder 74, and the square magnetic plate 77 with the same magnetic pole as that of the magnetic cylinder 74 moves to the position directly below the magnetic cylinder 74, thereby generating a repulsive force on the magnetic cylinder 74. The magnetic cylinder 74 moves upward under the action of the repulsive force, thereby driving the cutting tool holder 73 to cut the precursor with a relatively large volume at the outlet end of the processing frame 72, so as to break it into a precursor with a relatively small volume, so as to facilitate subsequent contact with oxygen for oxidation reaction. When the force receiving rod frame 751 on the force receiving shaft body 75 moves away from the corresponding position of the force applying rod frame 8, it returns to the initial position under the action of the torsion spring 76 in a tightened potential state. The square magnetic plate 77 opposite to the magnetic cylinder 74 returns to the position directly below the magnetic cylinder 74, thereby generating an attractive force on the magnetic cylinder 74, so that the cutting tool holder 73 moves away from the outlet end of the processing frame 72. Under the structure design of the present application, the precursor in the tank body 1 can be effectively processed, thereby effectively controlling the reaction volume of the precursor, so that the precursor and oxygen can fully react.
