Description

Technical Field

[0001] The present invention belongs to the technical field of chemical equipment, and particularly relates to a liquid feeding structure of a mixer reactor. Background Art

[0002] Fluorine chemical industry occupies an important position in the national economy. Fluorine chemical products, with their excellent properties such as chemical resistance, high and low temperature resistance, aging resistance, low friction, and high insulation, are widely used in military, chemical, mechanical and other fields, and have become the fastest-growing, most high-tech and most promising products in the chemical industry. Anhydrous hydrogen fluoride is a strong oxidizing agent and is also the basic raw material for producing elemental fluorine, various fluorine refrigerants, inorganic fluorides, and various organic fluorides. With the rapid development of the fluorine chemical industry, the demand for anhydrous hydrogen fluoride, the basic raw material for manufacturing fluorine chemical products, is increasing day by day.

[0003] In the prior art, most of this process is carried out in a traditional mechanically stirred enamel reactor. Such a production method results in a relatively high energy consumption during the entire reaction process while the production efficiency is not ideal enough.

[0004] For example, a Chinese utility model patent discloses a high-efficiency reactor for producing anhydrous hydrogen fluoride by the sulfuric acid method [Application No.: 201820651505.8]. This utility model patent includes a reaction tank and a cleaning device. A fixed clip is clamped at the upper end of the reaction tank. A fixed rod is welded on one side of the fixed clip located inside the reaction tank. One end of the fixed rod is fixedly provided with a connecting ring. A rotating ring is provided on the upper surface of the connecting ring. A rotating handle is fixedly provided on the outer surface of the rotating ring. A positioning pin rod is movably inserted on the surface of the rotating ring. The cleaning device includes a connecting rod, a turntable, a cleaning rod, a mounting seat and a cleaning roller. The upper end of the connecting rod movably penetrates through the connecting ring and the rotating ring. One end of the positioning pin rod penetrates through the rotating ring and is clamped on the surface of the connecting rod. The lower end of the connecting rod is vertically provided with a turntable. The cleaning rods are equally spaced and installed on the surface of the turntable. A mounting seat is vertically welded at the end of the cleaning rod. A rotating shaft is fixedly provided in the inner cavity of the mounting seat. A cleaning roller is rotatably provided on the surface of the rotating shaft, and the surface of the cleaning roller is tangent to the inner wall of the reaction tank.

[0005] This utility model patent has the advantage that the cleaning roller can be in contact with the surface of the reaction tank to achieve the purpose of cleaning dirt and sediment, but it still does not solve the above problems. Summary of the Invention

The feeding mechanism includes at least one feeding component rotatably connected to the surface of the feeding shaft and at least one temporary storage cavity located inside the feeding shaft. Rotating the feeding component can make the temporary storage cavity communicate with or isolate from the outside.

[0013] In the above-mentioned mixer reactor for the fluorochemical industry, the feeding assembly includes a first fin and a second fin. The first fin is rotatably connected to the feeding shaft through a first rotating shaft. The first rotating shaft is located at one end of the first fin away from the second fin. The second fin is rotatably connected to the feeding shaft through a second rotating shaft. The second rotating shaft is located at one end of the second fin away from the first fin. The surface of the feeding shaft is provided with a first opening and a second opening respectively opposite to the first fin and the second fin. Both the first opening and the second opening are communicated with the temporary storage cavity. Rotating the first fin can open or close the first opening, and rotating the second fin can open or close the second opening.

[0014] In the above-mentioned mixer reactor for the fluorochemical industry, inclined surfaces are provided on both the side of the first fin away from the first rotating shaft and the side of the second fin away from the second rotating shaft. Rotating the first fin or the second fin can make the inclined surface fit on the feeding shaft. A guiding convex is further provided in the temporary storage cavity. The upper surface of the guiding convex is a guiding arc surface. The inner surfaces of the first fin and the second fin are arc surfaces, and rotating the first fin or the second fin can make the guiding arc surface coincide with the arc center of the inner surface of the first fin or the second fin.

[0015] In the above-mentioned mixer reactor for the fluorochemical industry, the sealing structure includes an outer shell and an end cover fitted on the outer shell.

[0018] Compared with the existing technology, the advantages of the present invention are as follows:

[0019] 1. The present invention adopts a structure in which a power system, a reaction system, a degassing system, etc. are connected in sequence, and has lower energy consumption and higher production efficiency compared with the reaction method using a stirring reaction kettle in the prior art.

[0020] 2. The mixer reactor provided by the present invention gradually adds the liquid-phase reactant, i.e., sulfuric acid solution, to the solid-liquid mixing area through a liquid-phase pipeline, thereby controlling the actual reaction area within the solid-liquid mixing area, controlling the reaction process, and effectively controlling the intensity of the reaction.

[0021] 3. Since a paste-like by-product calcium sulfate is generated after the reaction, the mechanical stirring enamel reaction kettle in the prior art requires extremely high electrical energy to drive the reactants for reaction stirring during the reaction process. The present invention uses the rotation process of the main shaft to gradually sprinkle the solid materials at the bottom into the solid-liquid mixing area, greatly saving energy compared with the mixing method in the prior art.

[0022] 4. The present invention simultaneously provides an oil storage ring and packing that can be filled with an oil medium inside the accommodation cavity of the sealing system to jointly form a sealing system. The oil medium will penetrate into the packing during the rotation of the rotating shaft, so it has a better sealing effect compared with the prior art that uses a single sealing ring structure for sealing.

[0023] 5. The present invention is provided with an oil receiving groove on the ring body that can communicate with the oil storage cavity located between the ring body and the inner ring, so that the oil medium can be injected into and stored in the oil storage cavity through the oil receiving groove, thereby ensuring that the oil medium is always in a sufficient state in the sealing structure and ensuring the high efficiency of lubrication and sealing.

Detailed implementation manners

[0034] The following further describes the present invention in detail with reference to the accompanying drawings and specific implementation manners.

[0035] Embodiment 1

[0036] This embodiment provides a mixer reactor for the fluorochemical industry, as Figure 1 shown, including a mounting base b, on which a reaction system c and a power system d are provided. The power system d is located on one side of the reaction system c, and one end of the main shaft 3 is drivingly connected to the power system d. The end of the main shaft 3 away from the power system d extends into the reaction system c. A sealing structure a is further provided between the power system d and the reaction system c. The sealing structure a is sleeved outside the main shaft 3. A degassing system e is further provided on the side of the reaction system c away from the power system d. The degassing system e is communicated with the reaction system c.

[0037] In the present invention, during use, the power system d drives the main shaft 3 to rotate, so as to realize the transfer of the solid-phase material and the contact with the liquid-phase material, and thus a reaction occurs in the reaction system c. After the reaction is completed, it is transported to the degassing system e for degassing. Therefore, the present invention adopts a structure in which the power system d, the reaction system c, the degassing system e, etc. are connected in sequence, and has lower energy consumption and higher production efficiency compared with the reaction method using a stirring reaction kettle in the prior art.

[0038] Combined with Figure 2 and Figure 3As shown, the reaction system c includes a reaction cylinder body 1. A storage space 2 for containing solid-phase materials 100 is provided inside the reaction cylinder body 1. A main shaft 3 is rotatably connected inside the reaction cylinder body 1, and the outer surface of the main shaft 3 is in contact with the storage space 2. Above the storage space 2, there is a solid-liquid mixing area 4 for the reaction to occur. A liquid-phase pipeline 5 is connected to the reaction cylinder body 1 and communicates with the solid-liquid mixing area 4. On one side of the reaction cylinder body 1, a solid-phase feeding cylinder body 8 is fixedly connected. A feeding port 9 is provided at the upper end of the solid-phase feeding cylinder body 8. The main shaft 3 passes through the solid-phase feeding cylinder body 8 and extends into the reaction cylinder body 1. A feeding screw thread 10 is fixedly connected to the outer wall of the main shaft 3 located inside the solid-phase feeding cylinder body 8, and the feeding screw thread 10 spirally extends along the axial line direction of the main shaft 3.

[0039] During use, the solid-phase material 100, namely fluorite powder, is added into the solid-phase feeding cylinder body 8 through the feeding port 9. The main shaft 3 is driven to rotate. At this time, the solid-phase material 100 is transferred into the storage space 2, and the materials that have completed the reaction in the storage space 2 are squeezed into the degassing system e for degassing. The liquid-phase material, namely sulfuric acid solution, is continuously and evenly conveyed into the solid-liquid mixing area 4 through the liquid-phase pipeline 5 and contacts the fluorite powder on the surface layer to react. Therefore, the mixer reactor provided by the present invention gradually adds the liquid-phase reactant, namely sulfuric acid solution, to the solid-liquid mixing area 4 through the liquid-phase pipeline 5, thereby controlling the actual reaction area within the solid-liquid mixing area 4, controlling the reaction process, and effectively controlling the intensity of the reaction.

[0040] As Figure 2 shown, at the end of the liquid-phase pipeline 5 close to the reaction cylinder body 1, there is a spray head 6. The liquid-phase pipeline 5 communicates with the solid-liquid mixing area 4 through the spray head 6. Preferably, a plurality of spray heads 6 are provided, and the inclination angles of each spray head 6 are different. This can ensure the uniformity of the spraying of the sulfuric acid solution, thereby ensuring that the reaction occurs uniformly within the solid-liquid mixing area 4.

[0041] As Figure 2 shown, a negative-pressure pipeline 7 is also connected to the reaction cylinder body 1, and the negative-pressure pipeline 7 communicates with the solid-liquid mixing area 4. The negative-pressure pipeline 7 can timely extract the hydrogen fluoride gas generated by the reaction from the reaction system, breaking the entire reaction balance, causing the reaction to move to the right, and improving the conversion rate of the hydrogen fluoride product.

[0042] As Figure 6, the sealing structure a includes a housing and an end cap a200 fitted on the housing. The housing and the end cap a200 enclose a sealing system accommodation cavity a300. At least one oil storage ring a400 is provided in the sealing system accommodation cavity a300. At least one circle of packing a500 connected to the oil storage ring a400 is provided on the side surface of the oil storage ring a400. One end of an oil injection pipe a600 extends into the sealing system accommodation cavity a300 and is connected to the oil storage ring a400. Among them, the packing a500 is made of graphite-reinforced PTFE material.

[0043] During use, the packing a500 and the oil storage ring a400 are installed into the sealing system accommodation cavity a300. The oil medium is injected into the oil storage ring a400 through the oil injection pipe a600. During the operation of the main shaft 3, the oil medium supplies oil to the left and right packings a500 centered on the oil storage ring a400, realizing circumferential and axial sealing of the main shaft 3. Therefore, in the present invention, an oil storage ring a400 with an internally fillable oil medium and a packing a500 are simultaneously provided in the sealing system accommodation cavity a300 to jointly form a sealing system. The oil medium will penetrate into the packing a500 during the rotation of the main shaft 3. Therefore, compared with the prior art that uses a single sealing ring structure for sealing, it has a better sealing effect.

[0044] As Figure 6 shown, several oil storage rings a400 are provided. Three circles of packing a500 are provided between adjacent two oil storage rings a400. The side surface of the packing a500 is pressed on the side surface of the oil storage ring a400.

[0045] Preferably, the axis lines of the oil storage ring a400 and the packing a500 coincide with each other. This can ensure better sealing performance of the entire sealing system.

[0046] Combined Figure 6 and Figure 7 shown, the oil storage ring a400 includes a ring body a1. An inner ring a2 is also fixedly connected inside the ring body a1. The center of the inner ring a2 coincides with the center of the ring body a1. The inner surface of the inner ring a2 fits with an installation space a3 for installing the main shaft a3. There is an oil storage cavity a4 between the inner ring a2 and the ring body a1. An oil receiving groove a5 recessed inward from the outer surface of the ring body a1 is provided on the outer surface of the ring body a1. The oil receiving groove a5 is connected to the oil storage cavity a4. The oil injection pipe a600 is connected to the oil receiving groove a5. One end of the oil receiving groove a5 away from the outer surface of the ring body a1 penetrates through the inner ring a2 and is connected to the installation space a3.

[0047] During use, the oil receiving tank a5 is connected to the oil injection pipe a600, and the oil medium is injected into the oil storage cavity a4 through the oil receiving tank a5. The main shaft 3 is located in the installation space a3. During rotation, the oil medium in the oil storage cavity a4 penetrates to the surface of the main shaft 3 through the other end of the oil receiving tank a5, and the rotation process of the main shaft 3 can promote the uniform distribution of the oil medium. Therefore, in the present invention, an oil receiving tank a5 is provided on the ring body a1 and can communicate with the oil storage cavity a4 located between the ring body a1 and the inner ring a2, so that the oil medium can be injected into and stored in the oil storage cavity a4 through the oil receiving tank a5, thereby ensuring that the oil medium is always in a sufficient state in the sealing structure and ensuring the high efficiency of lubrication and sealing.

[0048] Combined with Figure 7 and Figure 8 As shown, a positioning groove a6 recessed inward from the outer surface of the ring body a1 is further provided on the outer surface of the ring body a1, and the positioning groove a6 is isolated from the oil storage cavity a4. The positioning groove a6 can be used to assist in positioning the installation position of the sealing ring.

[0049] Preferably, the positioning grooves a6 are symmetrically arranged on both sides of the oil receiving tank a5. The included angle between the positioning groove a6 and the oil receiving tank a5 is 45 degrees. That is, taking the position of the oil receiving tank a5 as the circumferential 90 degrees, a positioning groove a6 is provided at the circumferential 45 degrees and the circumferential 135 degrees respectively.

[0050] Combined with Figures 7 - 9 As shown, a plurality of oil return grooves a7 recessed inward from the side surface of the inner ring a2 are provided on the side surface of the inner ring a2, and the installation space a3 is connected to the oil storage cavity a4 through the oil return grooves a7.

[0051] During the use process, the excessive oil medium on the surface of the rotating shaft will flow back to the oil storage cavity a4 through the oil return grooves a7 after being squeezed, thereby forming a flow cycle of the oil medium and preventing excessive oil medium from staying in the installation space a3.

[0052] Specifically, the oil return groove a7 is surrounded by two side surfaces a71 and a bottom surface a72. The bottom surface a72 is an inclined surface, and the thickness of the bottom surface a72 gradually decreases from the side close to the installation space a3 to the side close to the oil storage cavity a4. The side surface a71 is an arc surface. This can effectively reduce the flow resistance when the oil medium flows back to the oil storage cavity a4.

[0053] Preferably, a plurality of oil return grooves a7 are provided and are circumferentially and evenly distributed along the axis of the inner ring a2. This can further ensure the uniformity of the oil medium distribution.

[0054] Such as Figure 8As shown, a threaded groove a8 that is recessed into the interior of the inner ring a2 is further provided on the inner surface of the inner ring a2. The threaded groove a8 spirally extends along the axial direction of the inner ring a2. A sealing rib a9 for improving the sealing effect is provided inside the threaded groove a8 or between two adjacent threaded grooves a8. The sealing rib a9 is fixedly connected to the inner ring a2.

[0055] Among them, the width of the sealing rib a9 gradually decreases from one end close to the inner ring a2 to the other end, and the width at the narrowest part of the sealing rib a9 is less than half of the width at the widest part of the sealing rib a9. The sealing rib a9 is made of an elastic material, for example, it can be made of the same material as the sealing ring.

[0056] That is, a number of sealing ribs a9 that spirally extend along the inner surface of the inner ring a2 are fixedly provided on the inner surface of the inner ring a2. The structure of the sealing rib a9 is thicker at the bottom and thinner at the top. During use, under the extrusion of the rotating shaft, some of the sealing ribs a9 will be bent, thereby further improving the sealing effect.

[0057] Embodiment 2

[0058] This embodiment provides a mixer reactor for the fluorochemical industry. Its specific structure is generally the same as that in Embodiment 1, except for the specific structure of the main shaft 3. Combining Figure 4 and Figure 5 As shown, the main shaft 3 includes a feeding shaft 31. One end of the feeding shaft 31 is fixedly connected to a connecting shaft 32. The cross-sectional area of the feeding shaft 31 is more than 4 times that of the connecting shaft 32. A feeding mechanism 33 for conveying the solid-phase material 100 in the storage space 2 to the solid-liquid mixing area 4 is further provided on the feeding shaft 31.

[0059] Since the reaction of using fluorite and sulfuric acid to produce hydrogen fluoride will generate a paste-like by-product calcium sulfate, in the prior art, a mechanically stirred enamel reactor requires a large amount of electric energy to drive the reactants to react and stir during the reaction process. During the rotation of the main shaft 3 in the present invention, the feeding mechanism 33 on the feeding shaft 31 gradually throws the solid-phase material 100 at the bottom into the solid-liquid mixing area 4, greatly saving energy compared with the mixing method in the prior art.

[0060] Combining Figure 4 and Figure 5 As shown, the feeding mechanism 33 includes at least one feeding component 34 rotatably connected to the surface of the feeding shaft 31 and at least one temporary storage cavity 35 located inside the feeding shaft 31. Rotating the feeding component 34 can make the temporary storage cavity 35 communicate with or be isolated from the outside.

[0061] Specifically, the feeding assembly 34 includes a first fin 341 and a second fin 342. The first fin 341 is rotatably connected to the feeding shaft 31 through a first rotating shaft 343. The first rotating shaft 343 is located at one end of the first fin 341 away from the second fin 342. The second fin 342 is rotatably connected to the feeding shaft 31 through a second rotating shaft 344. The second rotating shaft 344 is located at one end of the second fin 342 away from the first fin 341. A first opening 345 and a second opening 346 are provided on the surface of the feeding shaft 31 opposite to the first fin 341 and the second fin 342 respectively. Both the first opening 345 and the second opening 346 are communicated with the temporary storage cavity 35. Rotating the first fin 341 can open or close the first opening 345, and rotating the second fin 342 can open or close the second opening 346. The opening and closing of the first fin 341 and the second fin 342 can be controlled by using a telescopic rod structure or other structures commonly used in the prior art.

[0062] Preferably, there are three feeding assemblies 34 and they are evenly distributed circumferentially along the surface of the feeding shaft 31. There are three temporary storage cavities 35 and they correspond to the feeding assemblies 34 one by one. This can effectively improve the production efficiency.

[0063] During use, the feeding shaft 31 rotates, thereby driving the entire feeding assembly 34 to perform a rotational movement centered on the axis of the feeding shaft 31. Combining Figure 3 As shown, when the feeding assembly 34 rotates to the left side of the main shaft 3 shown in Figure 3 the first fin 341 is buried in the solid-phase material 100. At this time, rotate the first fin 341 to open the temporary storage cavity 35, and part of the solid-phase material 100 enters the temporary storage cavity 35. Then rotate the first fin 341 to close the temporary storage cavity 35, and at the same time, the rotational resistance of the feeding shaft 31 can also be reduced. When the feeding assembly 34 rotates to the right side of the main shaft 3 shown in Figure 3 the second fin 342 is located above the solid-liquid mixing area 4. At this time, the solid material 100 in the temporary storage cavity 35 is transferred to one end close to the second fin 342 under the action of gravity. Rotate the second fin 342 so that the solid material 100 is discharged along the second fin 342 into the solid-liquid mixing area 4. Repeat this process to achieve continuous reaction.

[0064] As Figure 5 shown, inclined surfaces 347 are provided on the side of the first fin 341 away from the first rotating shaft 343 and the side of the second fin 342 away from the second rotating shaft 344. Rotating the first fin 341 or the second fin 342 can make the inclined surface 347 fit on the feeding shaft 31. In this way, after transporting the solid-phase material 100, there will be no solid-phase material 100 remaining on the inclined surface 347, avoiding the problem that the first fin 341 and the second fin 342 cannot completely close the temporary storage cavity 35.

[0065] As Figure 5 shown, a material guiding protrusion 351 is further provided in the temporary material storage cavity 35. The upper surface of the material guiding protrusion 351 is a material guiding arc surface 352. The inner surfaces of the first fin 341 and the second fin 342 are arc surfaces, and rotating the first fin 341 or the second fin 342 can make the material guiding arc surface 352 coincide with the center of the arc of the inner surface of the first fin 341 or the second fin 342. In this way, the process of the solid-phase material 100 entering and discharging from the temporary material storage cavity 35 can be smoother, improving the production efficiency.

Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar ways for substitution, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
