Description

Technical Field

[0001] The invention relates to the field of desulfurizing agent preparation, in particular to a preparation system of a composite desulfurizing agent, and also to a preparation method of a composite desulfurizing agent. Background Art

[0002] Currently, composite desulfurizers are usually produced using reactors. However, after the raw materials are added to the reactor, since the solid density in the raw materials is greater than the liquid density, the solids are mainly concentrated on the lower side of the reactor, resulting in the solids on the lower side being unable to fully contact the liquid, thereby reducing the solid-liquid mixing speed and making the production efficiency of the desulfurizer low.

[0003] The currently disclosed Chinese patent CN118454412A desulfurizer and production reactor includes a base, an outer shell is fixedly connected to the upper side of the base, a feed port is arranged on the upper side of the side wall of the outer shell, a drain port is arranged on the lower side of the side wall of the outer shell, and a discharge port is arranged at the bottom of the outer shell, a servo motor is fixedly connected to the base, an output shaft of the servo motor is fixedly connected to a rotating shaft rotatably connected to the outer shell close to the base, a symmetrically distributed fixed plate is fixedly connected to the rotating shaft, a sliding rod is limitedly slidably connected to the fixed plate, a U-shaped rod is arranged at one end of the sliding rod away from the adjacent fixed plate, the U-shaped rod is fixedly connected to an arc plate, the arc plate is arranged with evenly distributed through holes, the arc plate is fixedly connected to an intercepting plate, the intercepting plate is arranged with evenly distributed through holes, the sliding rod drives the arc plate to move upward through the U-shaped rod to lift the solid at the bottom of the outer shell, and a lifting mechanism is arranged in the outer shell to drive the symmetrically distributed sliding rods to move longitudinally.

[0004] According to the above patent, the solids at the bottom of the shell are lifted to the middle and upper side of the shell so that the solids are evenly dispersed in the shell. In the process of the solids rising and falling, the solids are crushed by the friction and squeezing of the extrusion plate and the arc plate, thereby increasing the dissolution rate of the solids and accelerating the mixing rate of the solution and the solids in cooperation with the rotation of the parts on the rotating shaft. In the process of the solution precipitation, the arc plate will guide the sediment sinking downward in the shell to the lower side so that the sediment settles quickly. However, although the patent improves the mixing efficiency by lifting and dispersing the solids, the arc plate at the bottom of the shell cannot completely lift all the materials, resulting in some raw materials in the corners not being fully mixed. Therefore, there is a need for a preparation system that can ensure that the raw materials and liquids are fully mixed. Summary of the invention

[0005] In view of the problems existing in the prior art, a preparation system of a composite desulfurizer is provided. The present invention allows raw materials to enter the interior through a pipeline inlet, and promotes the raw materials deposited at the bottom of the tank to be transported upward under the action of a spiral auger, so that the solid raw materials and the liquid raw materials are fully mixed during the stirring process of the agitator, and the raw materials at the pipeline inlet are dispersed by the material shifting plate, thereby achieving an anti-blocking effect.

[0006] In order to solve the problems of the prior art, the present invention provides a preparation system of a composite desulfurizer, comprising a tank body with a feeding port and a liquid feeding port, and an agitator arranged therein, the bottom of the tank body is an inverted cone structure, a pipe is vertically extended upward from the center of the bottom of the tank body, the lower half of the pipe is provided with a plurality of inlets flush with the bottom surface of the tank body around its circumferential direction, the lower end of the pipe extends downward through the bottom of the tank body and the lower end of the pipe is a closed end, a discharge port is provided on one side of the pipe close to the closed end, a spiral auger that is synchronously rotated by the drive of the agitator is provided in the pipe, the spiral auger is used to transport the raw materials entering the pipe upward to the upper end of the pipe and fall out from the opening at the upper end of the pipe, a plurality of material stripping plates are provided around the pipe corresponding to the inlet, the material stripping plates are used to prevent the inlet from being blocked by a large amount of accumulated raw materials, a synchronous driving mechanism is provided on the pipe for synchronously driving all the material stripping plates to act, when the synchronous driving mechanism drives all the material stripping plates to act at the same time, all the material stripping plates reciprocate along a direction perpendicular to the pipe, so that a large amount of raw materials located near the inlet are pushed outward.

[0007] Preferably, a hinged portion is fixedly provided on the pipeline to which the upper end of the material stripping plate is rotatably connected, the material stripping plate has a hinged shaft rotatably connected to the hinged portion, a movable gap is left between the lower end of the material stripping plate and the conical surface at the bottom of the tank body, a torsion spring is fixedly connected between the hinged shaft and the hinged portion, when the torsion spring is in a state of no external force, the lower end of the material stripping plate is close to the conical surface at the bottom of the tank body, so that the material stripping plate is in a starting position before swinging outward.

[0008] Preferably, the fixed sleeve on the pipeline is provided with a ring sleeve located between all the material stripping plates, the lower half of the ring sleeve has a guiding surface facing the conical surface of the bottom of the tank body, and a guiding channel for the quantitative raw materials to slide toward the inlet direction is formed between the guiding surface and the conical surface, and the upper half of the ring sleeve has an inclined surface for preventing the raw materials from being retained.

[0009] Preferably, the upper half of the ring sleeve is fixed with a buffer washer, which is located on the inner side of all the stripper plates. When the stripper plate swings outward and then resets under the action of the torsion spring, the stripper plate is supported on the buffer washer to prevent the stripper plate from swinging excessively inward due to pressure.

[0010] Preferably, the outer wall of the buffer gasket is provided with a plurality of chutes for the raw materials to pass through around the outer wall, and the chutes are used to prevent the raw materials from being clamped between the material stripping plate and the buffer gasket and affecting the swing amplitude of the material stripping plate.

[0011] Preferably, the synchronous drive mechanism includes a lifting sleeve with a sliding sleeve arranged on the pipeline, and a linkage component respectively connected between the lifting sleeve and each material stripping plate. The tank body is provided with a driver for driving the lifting sleeve to slide along the pipeline. When the lifting sleeve moves downward along the pipeline, all the material stripping plates swing outward under the drive of the corresponding linkage component. Conversely, when the lifting sleeve moves upward along the pipeline, all the material stripping plates are reset inward under the action of the corresponding torsion springs.

[0012] Preferably, the linkage assembly includes a pull rope fixedly connected between the lifting sleeve and the material stripping plate, and a guide wheel for supporting the pull rope. The guide wheel is rotatably arranged on the outside of the pipeline, and the pull rope passes over the top of the guide wheel. When the lifting sleeve moves downward, the pull rope portion between the guide wheel and the lifting sleeve is pulled downward, and at the same time, the pull rope portion between the guide wheel and the material stripping plate is pulled upward, so that the material stripping plate rotates outward with the hinge as the axis. When the lifting sleeve moves upward, the pull rope is relaxed, and the material stripping plate is reset under the action of the torsion spring.

[0013] Preferably, there is a retaining ring fixedly mounted on the pipe below the lifting sleeve, and the lower end of the lifting sleeve has an outer edge that can contact the retaining ring. When the lifting sleeve moves downward until its outer edge contacts the retaining ring, the outward swing of the material stripping plate reaches the maximum amplitude.

[0014] Preferably, the agitator has an electric shaft fixedly connected to the spiral auger, and a stirring rod fixedly arranged on the electric shaft and extending deep into the tank body. The electric shaft is also provided with a cover, which is located above the pipeline and its edge is close to the inner wall of the tank body. The cover has a conical structure. When the raw materials are put into the tank body, the raw materials slide down along the conical surface of the cover toward the surrounding side to prevent the raw materials from accumulating at the opening at the upper end of the pipeline.

[0015] The present invention also provides a method for preparing a composite desulfurizing agent, comprising the following steps:

[0016] S1. Accurately weigh the solid and liquid raw materials and add them into the tank through the feeding port and liquid feeding port according to the formula;

[0017] S2. Start the agitator to preliminarily mix the raw materials in the tank to ensure uniform distribution;

[0018] S3, the raw materials slide into the interior through multiple inlets of the pipeline, and then the spiral auger pushes the solid raw materials to the top and then falls back into the liquid layer;

[0019] S4, the cycle is repeated until the raw materials reach a highly uniform mixed state in the tank.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention allows raw materials to enter the interior of the pipeline through multiple inlets opened around the lower half of the pipeline, and promotes the raw materials deposited at the bottom of the tank to be transported upward under the action of the spiral auger, so that the solid raw materials and the liquid raw materials are fully mixed during the stirring process of the stirrer, and the raw materials at the pipeline inlet are dispersed when the material-diverting plate pushes the raw materials outward, which has an anti-blocking effect on the inlet, realizes the circulation and repeated mixing of the raw materials, and greatly improves the mixing efficiency and uniformity.

[0022] 2. The present invention forms a guide channel between the ring sleeve and the bottom of the tank body, so that the deposited raw materials can go straight to the inlet of the pipeline along the guide channel, and the guide channel only allows a fixed amount of raw materials to flow continuously, thereby avoiding the situation where a large amount of raw materials accumulate at the inlet and cause inlet blockage. The precise raw material guiding and reduced blockage risk jointly promote more complete mixing of solid and liquid raw materials under the action of the agitator, thereby improving the uniformity and quality consistency of the desulfurizer product.

[0023] 3. The present invention provides support for the stripper plate through the elastic buffering effect of the buffer washer, alleviates the direct impact when the stripper plate is reset inward, effectively protects the stripper plate from damage, improves the smoothness of the operation of the stripper plate, and prevents the stripper plate from swinging inward excessively, causing damage to the torsion spring, and causing the stripper plate to contact with the bottom of the tank body and completely block the inlet, thereby ensuring that the stripper plate moves within a specified range and improving the smoothness of the raw materials entering the pipeline.

DETAILED DESCRIPTION

[0035] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] See also Figure 1-Figure 4As shown, a preparation system of a composite desulfurizer comprises a tank body 1 having a feeding port 11 and a liquid feeding port 12, and an agitator 2 arranged therein, the bottom of the tank body 1 is an inverted cone structure, a pipe 3 extends vertically upward from the center of the bottom of the tank body 1, the lower half of the pipe 3 is provided with a plurality of inlets 31 flush with the bottom surface of the tank body 1 around its circumferential direction, the lower end of the pipe 3 passes through the bottom of the tank body 1 and extends downward, and the lower end of the pipe 3 is a closed end, a discharge port 32 is provided on one side of the pipe 3 close to the closed end, and a spiral rotating synchronously driven by the agitator 2 is provided in the pipe 3 The spiral auger 4 is used to transport the raw materials entering the pipeline 3 upward to the upper end of the pipeline 3 and drop out from the opening at the upper end of the pipeline 3. A plurality of material-dispensing plates 5 are arranged around the pipeline 3 corresponding to the inlet 31. The material-dispensing plates 5 are used to prevent the inlet 31 from being blocked by a large amount of accumulated raw materials. A synchronous driving mechanism 6 is arranged on the pipeline 3 for synchronously driving all the material-dispensing plates 5 to move. When the synchronous driving mechanism 6 drives all the material-dispensing plates 5 to move at the same time, all the material-dispensing plates 5 reciprocate and swing along a direction perpendicular to the pipeline 3, so that a large amount of raw materials near the inlet 31 are pushed outward.

[0037] The feeding port 11 is used for adding solid raw materials, and the liquid feeding port 12 is used for adding liquid raw materials. When preparing the desulfurizer, the solid raw materials are quantitatively added to the tank body 1 through the feeding port 11, and the liquid raw materials are accurately injected through the liquid feeding port 12 to ensure that the raw material ratio is accurate. Then the agitator 2 in the tank body 1 is started to perform preliminary mixing of the added raw materials to achieve preliminary uniform distribution. When the agitator 2 rotates, the spiral auger 4 also starts to work. The multiple inlets 31 opened around the lower half of the pipeline 3 allow the raw materials to slide into the interior of the pipeline 3 along the conical surface at the bottom of the tank body 1. The raw materials deposited at the bottom are transported upward along the pipeline 3 through the spiral auger 4 until they fall out of the opening at the upper end of the pipeline 3 to the upper half of the liquid. The area is conducive to sufficient mixing of liquid and solid. As the raw materials continue to enter the pipeline 3 from the inlet 31, a large amount of raw materials are easily accumulated at the inlet 31, causing blockage. The material-pickup plate 5 arranged around the pipeline 3 and located in the inlet 31 area can effectively push the raw materials accumulated at the inlet 31 outward and disperse them. All the material-pickup plates 5 are driven by the synchronous driving mechanism 6 to reciprocate synchronously, effectively avoiding the problem of blockage of the inlet 31 area due to raw material accumulation, and at the same time ensuring that the raw materials can continuously and evenly enter the pipeline 3, maintaining the continuity and efficiency of the entire mixing and conveying process, until the raw materials are mixed and the discharge port 32 is opened to be sent out.

[0038] See also Figure 2-Figure 8As shown, a hinged portion 51 is fixedly provided on the pipe 3 to which the upper end of the material-diverting plate 5 is rotatably connected. The material-diverting plate 5 has a hinged shaft 52 rotatably connected to the hinged portion 51. A movable gap is left between the lower end of the material-diverting plate 5 and the conical surface at the bottom of the tank body 1. A torsion spring 53 is fixedly connected between the hinged shaft 52 and the hinged portion 51. When the torsion spring 53 is in a state of no external force, the lower end of the material-diverting plate 5 is close to the conical surface at the bottom of the tank body 1, so that the material-diverting plate 5 is in a starting position before swinging outward.

[0039] An appropriate movable gap is reserved between the lower end of the stripper plate 5 and the conical surface at the bottom of the tank body 1 to prevent the stripper plate 5 from being obstructed in its swinging. When the torsion spring 53 is in a natural state, the stripper plate 5 will be slightly pulled to make its lower end close to the conical surface and in an initial position ready to swing. When the synchronous drive mechanism 6 is activated, the stripper plate 5 is driven to swing outward. At this time, the torsion spring 53 is in a torsion state. The stripper plate 5 effectively clears the raw material accumulation in the inlet 31 area to prevent blockage. When the synchronous drive mechanism 6 releases the driving force on the stripper plate 5, the torsion spring 53 acts to make the stripper plate 5 return to the initial position to be swung again. The synchronous drive mechanism 6 combined with the torsion spring 53 drives the stripper plate 5 to swing back and forth, thereby ensuring that the inlet 31 area of ​​the pipeline 3 can slide into the solid raw material smoothly.

[0040] See also Figure 2-Figure 7 and Fig. 9 As shown, a ring sleeve 33 is fixedly provided on the pipeline 3 and is located between all the material-diverting plates 5. The lower half of the ring sleeve 33 has a guiding surface that is opposite to the conical surface of the bottom of the tank body 1. A guiding channel 331 is formed between the guiding surface and the conical surface for the quantitative raw material to slide toward the inlet 31. The upper half of the ring sleeve 33 has an inclined surface for preventing the raw material from being retained.

[0041] The guiding surface of the lower part of the ring sleeve 33 and the conical surface at the bottom of the tank body 1 form a guiding channel 331, which can guide the raw materials deposited on the bottom of the tank to slide down along the conical surface and accurately guide them to the inlet 31, ensuring the directional flow of the raw materials. The guiding channel 331 can only allow a certain amount of raw materials to pass through, preventing a large amount of raw materials from accumulating at the inlet 31, and the inclined surface of the upper part of the ring sleeve 33 can effectively prevent the raw materials from being retained on the ring sleeve 33, ensuring that the raw materials will not accumulate here.

[0042] See also Figure 2-Figure 7 and Fig. 9 As shown, the upper half of the ring sleeve 33 is fixed with a buffer washer 34, and the buffer washer 34 is located on the inner side of all the material stripping plates 5. When the material stripping plate 5 swings outward and then returns to its original position under the action of the torsion spring 53, the material stripping plate 5 is supported on the buffer washer 34 to prevent the material stripping plate 5 from swinging excessively inward due to pressure.

[0043] The buffer washer 34 uses its elastic characteristics to provide a soft contact surface for the movement trajectory of the stripper plate 5. During the working cycle, each time the stripper plate 5 swings outward to clean the inlet 31 area and promote the flow of raw materials, the stripper plate 5 will reset inward under the action of the torsion spring 53. During this reset stage, the end of the stripper plate 5 does not directly hit the outer wall of the hard ring sleeve 33, but gently falls on the buffer washer 34, which effectively absorbs the impact force generated when the stripper plate 5 is reset, limits its excessive inward swing amplitude, and avoids damage or wear that may be caused by hard collision.

[0044] See also Figure 2-Figure 7 and Fig. 9 As shown, the outer wall of the buffer gasket 34 is provided with a plurality of chutes 341 for the raw materials to pass through around the outer wall. The chutes 341 are used to prevent the raw materials from being clamped between the material-diverting plate 5 and the buffer gasket 34 and affecting the swing amplitude of the material-diverting plate 5 .

[0045] When the raw material moves with the swing of the material stripper plate 5, the slide groove 341 on the buffer washer 34 effectively blocks any raw material particles that may be stuck between the material stripper plate 5 and the buffer washer 34, ensuring that the material stripper plate 5 maintains a specified swing amplitude and flexibility without being affected by external obstacles.

[0046] See also Figure 2-Figure 7 and Fig.10 As shown, the synchronous drive mechanism 6 includes a lifting sleeve 61 slidably mounted on the pipeline 3, and a linkage assembly 62 respectively connected between the lifting sleeve 61 and each material stripping plate 5. The tank body 1 is provided with a driver 63 for driving the lifting sleeve 61 to slide along the pipeline 3. When the lifting sleeve 61 moves downward along the pipeline 3, all the material stripping plates 5 are swung outward under the drive of the corresponding linkage assembly 62. Conversely, when the lifting sleeve 61 moves upward along the pipeline 3, all the material stripping plates 5 are reset inward under the action of the corresponding torsion springs 53.

[0047] The driver 63 has a lifting ring 631 that slides along the inner wall of the tank body 1, and an electric push rod 632 arranged on both sides of the lifting ring 631 for driving the lifting ring 631 to move up and down. A plurality of rack rods 6311 are fixedly connected between the lifting ring 631 and the lifting sleeve 61. With the drive of the electric push rod 632, the lifting ring 631 drives the lifting sleeve 61 to slide up and down along the pipeline 3. When the lifting sleeve 61 moves downward, all the material stripping plates 5 swing outward synchronously through the mechanical transmission of the linkage assembly 62. This action helps to clean up the raw materials accumulated in the inlet 31 area and ensure that the raw materials enter the pipeline 3 smoothly. On the contrary, when the lifting sleeve 61 slides upward, each material stripping plate 5 automatically resets inward under the elastic force of the preset torsion spring 53, preparing for the next round of swinging operation.

[0048] See also Figure 2-Figure 7 and Fig.10As shown, the linkage assembly 62 includes a pull rope 621 fixedly connected between the lifting sleeve 61 and the material stripping plate 5, and a guide wheel 622 for supporting the pull rope 621. The guide wheel 622 is rotatably arranged on the outside of the pipeline 3, and the pull rope 621 passes over the top of the guide wheel 622. When the lifting sleeve 61 moves downward, the pull rope 621 part between the guide wheel 622 and the lifting sleeve 61 is pulled downward, and at the same time, the pull rope 621 part between the guide wheel 622 and the material stripping plate 5 is pulled upward, so that the material stripping plate 5 rotates outward with the hinge part 51 as the axis. When the lifting sleeve 61 moves upward, the pull rope 621 is loosened, and the material stripping plate 5 is reset under the action of the torsion spring 53.

[0049] When the electric push rod 632 drives the hanging ring 631 to move the lifting sleeve 61 downward, the part of the pull rope 621 connected to the lifting sleeve 61 is pulled downward. At the same time, the other part of the pull rope 621 passing through the guide wheel 622 is pulled upward due to the rotation of the guide wheel 622, prompting the material removal plate 5 to rotate outward around its hinge point to achieve the purpose of cleaning and guiding the raw materials. Conversely, when the lifting sleeve 61 moves upward, the pull rope 621 relaxes and the previously accumulated tension is released. At this time, the torsion spring 53 begins to play a role, pushing the material removal plate 5 to overcome the slight resistance of the pull rope 621 and reset inward along the original path to prepare for the next working cycle.

[0050] See also Figure 2-Figure 7 and Fig.10 As shown, there is a retaining ring 611 fixedly mounted on the pipe 3 below the lifting sleeve 61, and the lower end of the lifting sleeve 61 has an outer edge 612 that can contact the retaining ring 611. When the lifting sleeve 61 moves downward until its outer edge 612 contacts the retaining ring 611, the outward swing of the material stripping plate 5 reaches the maximum amplitude.

[0051] With the drive of the electric push rod 632, the lifting sleeve 61 gradually moves downward along the pipeline 3. When the outer edge 612 of the lower end of the lifting sleeve 61 hits the retaining ring 611, the lifting sleeve 61 reaches its lowest point, and the material stripping plate 5 is at the maximum outward swing position. At this position, the lifting sleeve 61 is in direct contact with the retaining ring 611, which physically limits the material stripping plate 5 from continuing to move outward, ensuring that all the material stripping plates 5 simultaneously reach and remain at the maximum swing amplitude, preventing damage to the material stripping plates 5 that may be caused by excessive swinging.

[0052] See also Figure 2-Figure 7As shown, the agitator 2 has an electric shaft 21 fixedly connected to the spiral auger 4, and a stirring rod 22 fixedly arranged on the electric shaft 21 and extending deep into the tank body 1. A cover 23 is also sleeved on the electric shaft 21. The cover 23 is located above the pipe 3 and its edge is close to the inner wall of the tank body 1. The cover 23 has a conical structure. When the raw material is put into the tank body 1, the raw material slides along the conical surface of the cover 23 toward the surrounding side to prevent the raw material from accumulating at the opening at the upper end of the pipe 3.

[0053] When the raw materials are put into the tank body 1, the first thing they encounter is the cover 23 located above the pipe 3 and close to the inner wall of the tank body 1. The edge of the cover 23 is close to the tank wall, forming a surface inclined in all directions. Under the action of gravity, the raw materials are not directly accumulated above the opening of the pipe 3, but naturally slide along the inclined surface of the cover 23 to the surrounding side of the tank body 1, which effectively promotes the initial uniform distribution of the raw materials in the tank body 1. The existence of the cover 23 not only guides the flow of the raw materials, but also prevents the raw materials falling from above from entering the upper opening of the pipe 3, thereby maintaining the normal discharge of the upper opening of the pipe 3.

[0054] A method for preparing a composite desulfurizer is applied to a system for preparing a composite desulfurizer, comprising the following steps:

[0055] S1. Accurately weigh the solid and liquid raw materials and add them into the tank 1 through the feed port 11 and the liquid feed port 12 according to the formula;

[0056] S2, start the agitator 2 to preliminarily mix the raw materials in the tank 1 to ensure uniform distribution;

[0057] S3, the raw material slides into the interior through the multiple inlets 31 of the pipeline 3, and then the spiral auger 4 pushes the solid raw material to the top and then falls back into the liquid layer;

[0058] S4, the process is repeated until the raw materials are in a highly uniform mixed state in the tank body 1.

[0059] The present invention allows raw materials to enter the interior of the pipeline 3 through multiple inlets 31 opened around the lower half of the pipeline 3, and promotes the raw materials deposited at the bottom of the tank body 1 to be transported upward under the action of the spiral auger 4, so that the solid raw materials and the liquid raw materials are fully mixed during the stirring process of the stirrer 2, and the raw materials at the inlet 31 of the pipeline 3 are dispersed when the material plate 5 pushes the raw materials outward, which has an anti-blocking effect on the inlet 31, realizes the circulation and repeated mixing of the raw materials, and greatly improves the mixing efficiency and uniformity.

[0060] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.

The fixed sleeve on the pipe (3) is provided with a ring sleeve (33) located between all the material-diverting plates (5); the lower half of the ring sleeve (33) has a guide surface facing the conical surface of the bottom of the tank body (1); a guide channel (331) is formed between the guide surface and the conical surface for the quantitative raw material to slide toward the inlet (31); the upper half of the ring sleeve (33) has an inclined surface for preventing the raw material from being retained; The synchronous drive mechanism (6) comprises a lifting sleeve (61) which is slidably mounted on the pipeline (3), and a linkage assembly (62) which is respectively connected between the lifting sleeve (61) and each material-diverting plate (5). The tank body (1) is provided with a driver (63) for driving the lifting sleeve (61) to slide along the pipeline (3). When the lifting sleeve (61) moves downward along the pipeline (3), all the material-diverting plates (5) are swung outward under the drive of the corresponding linkage assembly (62). Conversely, when the lifting sleeve (61) moves upward along the pipeline (3), all the material-diverting plates (5) are reset inward under the action of the corresponding torsion springs (53). The linkage assembly (62) comprises a pull rope (621) fixedly connected between the lifting sleeve (61) and the material stripping plate (5), and a guide wheel (622) for supporting the pull rope (621). The guide wheel (622) is rotatably arranged outside the pipe (3). The pull rope (621) passes over the guide wheel (622). When the lifting sleeve (61) moves downward, the pull rope (621) between the guide wheel (622) and the lifting sleeve (61) is pulled downward, and at the same time, the pull rope (621) between the guide wheel (622) and the material stripping plate (5) is pulled upward, so that the material stripping plate (5) rotates outward with the hinge portion (51) as the axis. When the lifting sleeve (61) moves upward, the pull rope (621) is loosened, and the material stripping plate (5) is reset under the action of the torsion spring (53). The agitator (2) comprises an electric rotating shaft (21) fixedly connected to the spiral auger (4), and a stirring rod (22) fixedly arranged on the electric rotating shaft (21) and extending deep into the tank body (1). The electric rotating shaft (21) is also provided with a cover (23). The cover (23) is located above the pipe (3) and its edge is close to the inner wall of the tank body (1). The cover (23) is of a conical structure. When raw materials are put into the tank body (1), the raw materials slide down along the conical surface of the cover (23) toward the peripheral side, thereby preventing the raw materials from accumulating at the opening at the upper end of the pipe (3).

2. The preparation system of a composite desulfurizing agent according to claim 1, characterized in that: The upper fixed sleeve of the ring sleeve (33) is provided with a buffer washer (34), and the buffer washer (34) is located on the inner side of all the material-diverting plates (5). When the material-diverting plates (5) swing outwards and then return to their original positions under the action of the torsion spring (53), the material-diverting plates (5) are supported on the buffer washer (34), thereby preventing the material-diverting plates (5) from swinging inwards excessively due to pressure.

3. The preparation system of a composite desulfurizing agent according to claim 2, characterized in that: The outer wall of the buffer washer (34) is provided with a plurality of chute grooves (341) around its periphery for the raw material to pass through, and the chute grooves (341) are used to prevent the raw material from being clamped between the material shifting plate (5) and the buffer washer (34) to affect the swing amplitude of the material shifting plate (5).

4. The preparation system of a composite desulfurizing agent according to claim 1, characterized in that: A retaining ring (611) is provided below the lifting sleeve (61) and is fixedly sleeved on the pipe (3). The lower end of the lifting sleeve (61) has an outer edge (612) capable of contacting the retaining ring (611). When the lifting sleeve (61) moves downward until its outer edge (612) contacts the retaining ring (611), the outward swing of the material shifting plate (5) reaches a maximum amplitude.

5. A method for preparing a composite desulfurizing agent, applied to a system for preparing a composite desulfurizing agent according to any one of claims 1 to 4, characterized in that: The following steps are involved: S1. Accurately weigh the solid and liquid raw materials and add them into the tank (1) through the feed port (11) and the liquid port (12) according to the recipe; S2, starting the agitator (2) to preliminarily mix the raw materials in the tank (1) to ensure uniform distribution; S3, the raw materials slide into the interior through the multiple inlets (31) of the pipeline (3), and then the spiral auger (4) pushes the solid raw materials to the top and then falls back into the liquid layer; S4. Repeat the cycle until the raw materials reach a highly uniform mixed state in the tank (1).
