Description

Technical Field

[0001] This invention belongs to the field of sulfur preparation technology, specifically an insoluble sulfur processing and crushing component and a mixing reactor. Background Technology

[0002] The mixing reactor is the core reaction vessel in the production and purification of insoluble sulfur, often referred to as a "combined reactor." It plays a crucial role in connecting and integrating multiple process steps throughout the entire production process. Its internal processing and crushing components are primarily used to pulverize the agglomerated or clump-like sulfur powder formed during production. Its core structure typically includes a tank body, a feed hopper, a discharge hopper, an energy-saving motor, a rotating shaft, and crushing rods mounted on the outer wall of the rotating shaft. The working principle of this component is that the rotation of the shaft, in conjunction with the tank body, drives the crushing rods to effectively pulverize the agglomerated sulfur powder.

[0003] In existing processing and crushing components, due to the thermoplastic nature of sulfur, despite the presence of cooling systems, localized frictional heat in high-shear crushing zones still causes the sulfur surface to slightly melt. The molten sulfur readily adheres to the inner walls of the equipment, the rotor, or the screen. This makes it difficult for existing processing and crushing components to achieve precise, real-time classification, resulting in a product containing both over-ground ultrafine powder and incompletely broken coarse particles, with a wide particle size distribution and poor uniformity. Summary of the Invention

[0004] The purpose of this invention is to provide an insoluble sulfur processing and crushing component and a mixing reactor to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an insoluble sulfur processing and crushing assembly, comprising: The housing includes a conical shell, with a feed inlet fixedly connected to the top of the conical shell and a discharge plate movably installed at the bottom of the conical shell for removing the material after crushing. A crushing shaft, rotatably mounted on top of a conical shell, is used for crushing sulfur; A circulation section is fixedly installed on the bottom surface of the conical shell for circulating liquid inside the conical shell; A screening and grading section is fixedly installed on the inner wall of the conical shell and is used for grading sulfur in the vertical direction.

[0006] Preferably, the crushing shaft includes a shaft body, a bushing is fixedly installed on the upper part of the shaft body, a plurality of first plates and a plurality of liquid spray shells are fixedly connected to the curved surface of the bushing, a liquid channel is opened inside the shaft body, the liquid channel communicates with the plurality of liquid spray shells, and a plurality of cleaning and stirring sleeves are fixedly connected to the curved surface of the shaft body.

[0007] Preferably, the cleaning and stirring sleeve includes multiple cleaning shells and multiple liquid distribution shells. The lower curved surface of the cleaning shell has multiple spray holes. The interior of the cleaning shell is connected to a first tube, a second tube, and a third tube. The first tube, the second tube, and the third tube at the same horizontal position are all fixedly connected to the liquid distribution shell at the corresponding horizontal position. The liquid distribution shell is connected to the liquid channel and fixedly connected to the shaft.

[0008] Preferably, the circulation section includes a circulation pump, the outlet end of the circulation pump is fixedly connected to a liquid supply pipe, the suction end of the circulation pump is fixedly connected to a liquid suction pipe, and a filter is fixedly installed at the top end of the liquid suction pipe for filtering between sulfur powder and liquid, and supplying liquid to the liquid supply pipe.

[0009] Preferably, the screening and grading section includes a first conical plate, the bottom of which has a first sieve hole, and a plurality of second plates and a plurality of third plates are fixedly connected to the inner curved surface of the first conical plate, which cooperate with the first plate to perform preliminary crushing of sulfur.

[0010] Preferably, the screening and grading section includes a second cone plate and a third cone plate, wherein a second sieve hole is formed at the bottom of the second cone plate and a third sieve hole is formed at the bottom of the third cone plate.

[0011] Preferably, the cone angles at the bottom of the first, second, and third cone plates gradually decrease. Each of the first, second, and third cone plates contains a plurality of crushing balls. The diameter of the crushing balls inside the first cone plate is larger than the diameter of the first sieve hole, the diameter of the crushing balls inside the second cone plate is larger than the diameter of the second sieve hole, the diameter of the crushing balls inside the third cone plate is larger than the diameter of the third sieve hole, the diameter of the first sieve hole is larger than the diameter of the second sieve hole, and the diameter of the second sieve hole is larger than the diameter of the third sieve hole.

[0012] Preferably, the liquid supply pipe is connected to the liquid channel and is rotatably connected to the shaft.

[0013] Preferably, the upper plurality of cleaning shells are adapted to the upper curved surface of the first conical plate, and the internal spray holes are equal in diameter to the first sieve holes; the middle plurality of cleaning shells are adapted to the upper curved surface of the second conical plate, and the internal spray holes are equal in diameter to the second sieve holes; and the lower plurality of cleaning shells are adapted to the upper curved surface of the third conical plate, and the internal spray holes are equal in diameter to the third sieve holes.

[0014] A mixing reactor, including the insoluble sulfur processing and crushing components described above, is used for the production and preparation of insoluble sulfur.

[0015] In the insoluble sulfur processing crushing component and mixing reactor provided in this solution, a cleaning stirring sleeve is set up. While the sleeve is crushing the material as it rotates with the shaft, it continuously cleans the surface of the screening and grading section below, thereby keeping the sieve holes unobstructed and ensuring that qualified powder can be discharged in a timely manner. This avoids disorderly grinding of materials in a single chamber and ensures that once the particles are qualified, they are separated, greatly reducing the phenomenon of over-crushing.

[0016] Secondly, a circulating pump draws the liquid from the bottom and pumps it to the top liquid channel, where it is sprayed downwards through the spray nozzle. This not only increases the kinetic energy of the liquid but also creates a downward flow that actively pushes the material downwards, overcoming the effects of buoyancy and accelerating the settling and discharge of qualified particles. The liquid flow also directly penetrates the inside of the screen holes, forcibly flushing down sulfur particles stuck in the holes, thus completely solving the problem of blockage inside the screen holes.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] In the high-speed grinding zone of a mechanical mill, such as between the rotor and stator, or at the particle-to-particle collision points, mechanical energy is instantly converted into heat energy. Since sulfur is a poor conductor of heat, the cooling system can only remove heat from the equipment walls, but cannot effectively remove the high temperatures generated in the micro-areas during particle impact. This causes the particle surface temperature to momentarily exceed the softening point or even melting point of sulfur, resulting in a slightly molten and sticky surface. When these slightly molten sulfur particles come into contact with the edges of the sieve holes, they can seal the holes, preventing qualified fine powder from passing through the sieve. This forces the qualified fine sulfur powder to remain in the grinding chamber for further grinding, leading to over-grinding and the production of a large amount of unnecessary ultrafine powder.

[0021] like Figures 1 to 2 As shown, an embodiment of the present invention provides an insoluble sulfur processing and crushing assembly, comprising: The housing part 100 includes a conical shell 110, with a feed inlet 120 fixedly connected to the top of the conical shell 110 and a discharge plate 130 movably installed at the bottom of the conical shell 110 for removing the material after crushing. Crushing shaft 200 is rotatably mounted on the top of conical shell 110 for crushing sulfur; The circulation unit 300 is fixedly installed on the bottom surface of the conical shell 110 and is used for the circulation of liquid inside the conical shell 110. The screening and grading section 400 is fixedly installed on the inner wall of the conical shell 110 and is used for the vertical grading of sulfur. like Figures 1 to 3 As shown, the crushing shaft 200 includes a shaft body 210, a bushing 220 is fixedly installed on the upper part of the shaft body 210, a plurality of first plates 230 are fixedly connected to the curved surface of the bushing 220, and a plurality of cleaning and stirring sleeves 260 are fixedly connected to the curved surface of the shaft body 210. It should be noted that in this invention, the plurality of first plates 230 are divided into upper and lower groups, with a gap between the upper and lower parts of the two groups of first plates 230, and the plurality of first plates 230 in each group are arranged equidistantly around the circumference. like Figure 2 , Figure 3 , Figure 8 As shown, the screening and grading section 400 includes a first conical plate 410, with a first screen hole 420 at the bottom of the first conical plate 410. Multiple second plates 430 and multiple third plates 440 are fixedly connected to the inner curved surface of the first conical plate 410, cooperating with the first plates 230 for the initial crushing of sulfur. The screening and grading section 400 also includes a second conical plate 450 and a third conical plate 460, with a second screen hole 470 at the bottom of the second conical plate 450 and a third screen hole 480 at the bottom of the third conical plate 460. The cone angles at the bottom of the first cone plate 410, the second cone plate 450, and the third cone plate 460 gradually decrease. Each of the first cone plate 410, the second cone plate 450, and the third cone plate 460 contains multiple crushing balls. The diameter of the crushing balls inside the first cone plate 410 is larger than the diameter of the first sieve hole 420. The diameter of the crushing balls inside the second cone plate 450 is larger than the diameter of the second sieve hole 470. The diameter of the crushing balls inside the third cone plate 460 is larger than the diameter of the third sieve hole 480. The diameter of the first sieve hole 420 is larger than the diameter of the second sieve hole 470. The diameter of the second sieve hole 470 is larger than the diameter of the third sieve hole 480. It should be noted that in this invention, the middle parts of the first conical plate 410, the second conical plate 450, and the third conical plate 460 are all rotatably connected to the shaft 210, and the upper edges of the three are all fixedly connected to the conical shell 110. Multiple second plates 430 and multiple third plates 440 are all fixedly connected to the first conical plate 410. A gap is left between the second plates 430 and the third plates 440 in the same vertical direction for the rotation of the first plate 230, while the gap between two first plates 230 is for the passage of the second plate 430 or the third plate 440. The space above the first cone plate 410 is for initial sulfur crushing. A suitable amount of water and sulfur is added into this space through the feed inlet 120. The rotation of the shaft 210 drives the shaft sleeve 220, multiple first plates 230, multiple spray shells 240, and the cleaning and stirring sleeve 260 to rotate, causing the sulfur and liquid to be stirred and crushed. The rotation of the cleaning and stirring sleeve 260 also causes the crushing balls above the first cone plate 410 to rub and rotate, further crushing the sulfur. When the sulfur particles are smaller than or equal to the size of the first sieve hole 420, they will fall off. The sulfur falls above the second cone plate 450. The shaft 210 will drive the middle cleaning and stirring sleeve 260 to rotate, thereby crushing the sulfur above the second cone plate 450 a second time. When the sulfur particle size is less than or equal to the second sieve hole 470, it will fall above the third cone plate 460. The shaft 210 will drive the lower cleaning and stirring sleeve 260 to rotate, thereby crushing the sulfur above the third cone plate 460 a third time. When the sulfur particle size is less than or equal to the third sieve hole 480, it reaches the qualified size and falls to the bottom of the cone shell 110. It should be noted that during the rotation of multiple cleaning and stirring sleeves 260, the surfaces of the first cone plate 410, the second cone plate 450, and the third cone plate 460 in the screening and grading section 400 below are cleaned. To prevent sulfur from clogging the screen holes, this solution incorporates cleaning and stirring sleeves 260, which, while rotating with the shaft 210 to crush the sulfur, continuously clean the surfaces of the screening and grading section 400 (first cone plate 410, second cone plate 450, and third cone plate 460). This mechanical, active cleaning action effectively prevents the accumulation and solidification of slightly molten sulfur at the screen holes, thus keeping the screen holes clear and ensuring that qualified powder can be discharged in a timely manner. Secondly, an appropriate amount of water is added into the conical shell 110 from the feed inlet. Water, as a medium, can absorb the heat generated during the crushing process, reducing the risk of the sulfur particles reaching their slightly molten temperature.

[0022] In this design, both the conical shell 110 and the screening and grading section 400 (first conical plate 410, second conical plate 450, and third conical plate 460) adopt a conical design, with the cone angle at the bottom of the conical plates in the screening and grading section 400 gradually decreasing. This utilizes gravity to assist the downward flow of materials, combined with the agitation of the cleaning and stirring sleeve 260, to prevent material accumulation in dead corners and ensure smooth continuous production. The first plate 230 on the shaft 210 and the second plate 430 and third plate 440 on the first conical plate 410 have vertical gaps and pass through each other, forming a composite crushing effect similar to shearing and impact. Furthermore, crushing balls are placed above the first conical plate 410, second conical plate 450, and third conical plate 460. Driven by the cleaning and stirring sleeve 260, the crushing balls rub and rotate, further grinding the sulfur. The combination of plate shearing and ball grinding improves crushing efficiency and uniformity. The screening and grading section 400 has a three-stage screening and grading structure (first cone plate 410, second cone plate 450, and third cone plate 460). The sieve aperture decreases from top to bottom. Combined with crushing balls of different diameters, the material undergoes preliminary, secondary, and tertiary crushing. Once the particle size requirement of the corresponding level is met, the material can pass through the sieve aperture to enter the next level or be discharged. This avoids disorderly grinding of the material in a single chamber and ensures that the particles are separated as soon as they meet the requirements, greatly reducing over-grinding.

[0023] During the implementation of the above solution, the inventors discovered that a lot of water needs to be added to the inside of the conical shell 110, and the water has very poor vertical flow. Not only does it fail to cause the sulfur particles to settle downwards, but it also causes the sulfur particles to have buoyancy, which slows down their settling speed. Secondly, the above-mentioned mechanical active cleaning action can only clean the sulfur clogging the upper surface of the conical plate, and it still cannot clean the stubborn blockage points inside the sieve holes.

[0024] The crushing shaft 200 also includes multiple liquid spray shells 240. The shaft body 210 has a liquid channel 250 inside, which communicates with the multiple liquid spray shells 240. The liquid spray shells 240 are located in the gap between two adjacent first plates 230 in the upper group, and the multiple liquid spray shells 240 are also circumferentially equidistant. The bushing 220 has multiple through holes for communicating between the liquid channel 250 and the liquid spray shells 240. The liquid spray shells 240 can spray the liquid inside downwards so that the liquid falls on the sulfur below.

[0025] like Figure 2 , Figure 3As shown, the circulation unit 300 includes a circulation pump 310. The outlet end of the circulation pump 310 is fixedly connected to a supply pipe 320, and the suction end of the circulation pump 310 is fixedly connected to a suction pipe 330. A filter 340 is fixedly installed at the top end of the suction pipe 330 for filtering between sulfur powder and liquid, and supplying liquid to the supply pipe 320. The supply pipe 320 is connected to the liquid channel 250 and is rotatably connected to the shaft 210. It should be noted that in this invention, the circulating pump 310 is fixedly installed at the bottom of the conical shell 110, and the top of the suction pipe 330 and the filter 340 are both located inside the conical shell 110. The filter 340 can filter the liquid and qualified sulfur powder, so that the qualified sulfur powder remains inside the conical shell 110. Under the suction action of the circulating pump 310, the liquid passes through the suction pipe 330 and enters the interior of the supply pipe 320, and is finally supplied to the interior of the liquid channel 250. A portion of the liquid will enter the spray shell 240 and be sprayed out. The liquid will mix with the coarse sulfur powder above, which will not only remove the heat generated during crushing.

[0026] like Figures 2 to 6 As shown, the cleaning and stirring sleeve 260 includes multiple cleaning shells 261 and multiple liquid distribution shells 266. Multiple spray holes 262 are opened on the lower curved surface of the cleaning shell 261. The interior of the cleaning shell 261 is connected to a first tube 263, a second tube 264, and a third tube 265. The first tube 263, the second tube 264, and the third tube 265 at the same horizontal position are all fixedly connected to the liquid distribution shell 266 at the corresponding horizontal position. The liquid distribution shell 266 is connected to the liquid channel 250 and fixedly connected to the shaft 210. It should be noted that in this invention, the liquid supplied by the circulating pump 310 to the liquid channel 250 will also enter the interior of multiple liquid distribution shells 266. Through the first pipe 263, the second pipe 264, and the third pipe 265, the liquid is supplied to the interior of the cleaning shell 261. Finally, it is sprayed out from multiple spray holes 262 on the lower curved surface of the cleaning shell 261. The sprayed liquid will have an impact force on the sulfur clogging the sieve holes, causing it to pass through the sieve holes and enter the cone plate below.

[0027] The upper cleaning shells 261 are adapted to the upper curved surface of the first cone plate 410, and the internal spray holes 262 are equal in diameter to the first sieve hole 420. The middle cleaning shells 261 are adapted to the upper curved surface of the second cone plate 450, and the internal spray holes 262 are equal in diameter to the second sieve hole 470. The lower cleaning shells 261 are adapted to the upper curved surface of the third cone plate 460, and the internal spray holes 262 are equal in diameter to the third sieve hole 480.

[0028] It should be noted that by matching the diameter of the spray holes 262 at the bottom of the cleaning shell 261 with the diameter of the screen holes directly below, the pressure of the liquid sprayed out is increased, which can remove all the sulfur from the screen holes.

[0029] In the previous method, although water was added, it lacked directional propulsion and had poor fluidity, failing to effectively drive sulfur particles downwards to settle. Instead, buoyancy hindered particle settling, leading to reduced crushing efficiency. This method uses a circulating pump 310 to draw liquid from the bottom and pump it to the top liquid channel 250, from which it is sprayed downwards through the spray shell 240. This not only increases the kinetic energy of the liquid but also creates a downward flow, actively pressing the material downwards, overcoming the effects of buoyancy, and accelerating the settling and discharge of qualified particles. Furthermore, the liquid is no longer a static cooling medium but a continuously circulating coolant that carries away heat from the impact points, more effectively preventing sulfur from melting.

[0030] The spray nozzle 262 at the bottom of the cleaning shell 261 has the same diameter and is positioned corresponding to the screen hole directly below it. When the liquid is sprayed out through the tiny spray nozzle 262, it generates a high flow velocity and impact force. The high-pressure liquid column is directly injected into the inside of the screen hole, which can forcefully flush down the sulfur particles stuck in the hole, completely solving the problem of blockage inside the screen hole.

[0031] A mixing reactor, including the insoluble sulfur processing and crushing components described above, is used for the production and preparation of insoluble sulfur.

[0032] This design incorporates a cleaning and mixing sleeve 260, which, while rotating with the shaft 210 to crush materials, continuously cleans the surfaces of the screening and grading sections 400 (first cone plate 410, second cone plate 450, and third cone plate 460) below. This ensures unobstructed sieve openings, allowing qualified powder to be discharged promptly. It also prevents materials from being ground haphazardly within a single chamber, ensuring that qualified particles are separated immediately, thus significantly reducing over-grinding.

[0033] Secondly, the liquid at the bottom is drawn in by the circulating pump 310 and pumped to the liquid channel 250 at the top, and then sprayed downwards through the spray shell 240. This not only increases the kinetic energy of the liquid, but also forms a downward liquid flow, actively pressing the material downwards, overcoming the influence of buoyancy, accelerating the settling and discharge of qualified particles, and the liquid flow also directly enters the inside of the screen holes, forcibly flushing down sulfur particles stuck in the holes, completely solving the problem of blockage inside the screen holes.

[0034] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
