Description

Technical Field

[0001] This invention relates to the field of chloromethane production equipment technology, and more particularly to a chloromethane manufacturing equipment. Background Technology

[0002] Chloromethane is an organic compound with the chemical formula CH3Cl. It is a colorless, easily liquefied gas with an ether-like odor and a sweet taste. Currently, in the production of chloromethane, methane and chlorine are introduced into a reactor in a certain proportion, and the reaction products are cooled by a cooler to obtain liquid chloromethane. Alternatively, high-temperature, low-concentration hydrochloric acid generated from hydrochloric acid desorption can be fed to a feed mixer in a reactor, thoroughly mixed with gaseous methanol at a certain molar ratio, and then fed into the reactor, directly producing chloromethane without a catalytic reaction.

[0003] Currently, when mixing high-temperature, low-concentration hydrochloric acid with gaseous methanol in a reactor, the reaction time is relatively long. After the reaction, the high-temperature, low-concentration hydrochloric acid crystals form on the inner wall of the reactor. The reactor is equipped with scrapers to remove these crystals. After the reaction, the inner wall of the reactor needs cleaning, and the scrapers remove the crystals. However, after prolonged rotation, the side of the scraper that contacts the reactor wears down, creating gaps and affecting the cleaning effect, necessitating replacement. In existing reactors, the scraper rotates along with the stirring shaft. During mixing, the scraper continuously rotates, contacting and rubbing against the inner wall of the reactor, causing faster wear on the side that contacts the reactor, thus reducing the scraper's lifespan. Summary of the Invention

[0004] The purpose of this invention is to solve the problem mentioned in the background art above, where the scraper is constantly in contact with and rubs against the inner wall of the reactor, causing the side of the scraper that is in contact with the reactor to wear out faster, thus reducing the service life of the scraper.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A chloromethane manufacturing apparatus includes a tank, a crushing component, a scraping component, and a connecting component. The tank is equipped with a stirring motor, and a rotating shaft is connected to the output shaft of the stirring motor. A stirring rod for stirring and mixing is mounted on the rotating shaft. The crushing component is located inside the tank and connected to the rotating shaft. The crushing component is used to break up air bubbles in the liquid. The scraping component is movably located inside the tank and is used to scrape away crystals from the inner wall of the tank. The connecting component is located on the rotating shaft and includes a movable plate and a lower housing. The movable plate and the lower housing can be connected by an insertion joint. The movable plate and the lower housing are used for the transmission connection and transmission separation between the scraping component and the rotating shaft.

[0007] Preferably, the rotating shaft consists of an upper rotating rod and a lower rotating rod. A centrifugal impeller is provided on the lower rotating rod. Both the lower and upper rotating rods have cavities, which are connected by a connector. An air intake hole is provided on the upper rotating rod and communicates with its cavity. The cavity in the lower rotating rod is connected to the suction end of the centrifugal impeller. The upper and lower rotating rods are connected by a combined rod. When the rotating shaft drives the impeller to rotate, the impeller generates suction and draws methanol from above the tank into the cavity of the rotating shaft through the air intake hole, allowing the methanol gas to be transported to high-temperature, low-concentration hydrochloric acid for thorough mixing.

[0008] Preferably, the connecting component includes a protective shell, a movable plate, and a control component. The protective shell consists of an upper shell and a lower shell. The upper shell is located outside the upper rotating rod and is fixedly connected to it. The upper shell and the lower rotating rod are rotatably connected. The movable plate is movably disposed in the upper shell. The movable plate is provided with a screw and a gear. The gear is rotatably disposed in the upper shell and meshes with a gear ring. The connecting component allows the scraper to be connected to the rotating shaft for transmission when needed. This avoids the scraper rotating along with the stirring shaft during stirring, preventing the scraper from constantly contacting and rubbing against the inner wall of the reactor, reducing wear between the scraper and the reactor, and preventing gaps from easily forming between the scraper and the reactor, which could affect the cleaning effect of the scraper on the inner wall of the reactor.

[0009] Preferably, the upper housing is provided with a fixed plate, the gear has a protruding rotating end, the gear is rotatably connected to the fixed plate through the rotating end, and the gear is threadedly connected to the screw. Through the threaded engagement between the screw and the gear, the rotation of the gear can drive the screw to move linearly up and down, thereby driving the moving plate to move linearly up and down.

[0010] Preferably, the lower housing has multiple snap-fit ​​ends equidistantly spaced above and below the moving plate. The ends of the snap-fit ​​ends on the lower housing and the moving plate are both beveled. The beveled surfaces allow the snap-fit ​​ends on the moving plate to be inserted into the gaps between the snap-fit ​​ends on the lower housing when the moving plate moves downward, thus achieving a plug-in connection between the moving plate and the lower housing. This allows the moving plate to rotate with the rotating shaft, thereby causing the lower housing to rotate as well, which in turn causes the scraper to rotate and scrape and clean the inner wall of the tank.

[0011] Preferably, the gear ring has connecting ends protruding on both the upper and lower sides. The two connecting ends on the gear ring are rotatably connected to the ends of the upper rotating rod and the lower rotating rod, respectively. The lower rotating rod has a limiting end on its outer side. The movable plate is movably disposed on the outer side of the lower rotating rod. The movable plate has a limiting groove corresponding to the limiting end. The two connecting ends on the gear ring are rotatably connected to the upper rotating rod and the lower rotating rod through sealed bearings. The sealed bearings have good sealing performance, so that the cavity in the upper rotating rod and the cavity in the lower rotating rod can be sealed and connected.

[0012] Preferably, the scraping component includes a scraper, and a connecting rod is provided on the inner side of the scraper. The connecting rod is connected to the outer side of the lower shell. The scraper is in contact with the inner wall of the tank. When the tank needs to be cleaned after the reaction of chloromethane is completed, the inner wall of the tank can be scraped and cleaned by rotating the scraper.

[0013] Preferably, the control component includes a rotating rod, one end of which is provided with a connecting rod, the connecting rod being connected to the inner side of the gear ring. The other end of the connecting rod is connected to the rotating rod via a bevel gear assembly. One end of the rotating rod passes through the outer side of the upper rotating rod, and a rotating block is provided at one end of the rotating rod. The rotating rod is rotatably disposed within the cavity of the upper rotating rod. Power can be transmitted through the control component, thereby controlling the up-and-down movement of the moving plate on the drive connecting component.

[0014] Preferably, the crushing component further includes a second protective shell, a drive rod, and a support rod. One end of the drive rod is provided with a rotating plate, and the inner side of the rotating plate is provided with multiple crushing plates. The second protective shell is rotatably disposed below the centrifugal impeller, and the second protective shell is provided with a second set of conical teeth. When methanol from the top of the tank is drawn into the high-temperature, low-concentration hydrochloric acid liquid through the centrifugal impeller, a large number of methanol bubbles will be formed in the high-temperature, low-concentration hydrochloric acid. The crushing component can break up the large number of bubbles blown out, so that the methanol can be more fully mixed with the high-temperature, low-concentration hydrochloric acid.

[0015] Preferably, the second bevel gear assembly is connected to the drive rod via a rotating rod. The end of the drive rod away from the second bevel gear assembly is connected to a support rod. The lower end of the support rod is connected to the tank body. One end of the drive rod is rotatably mounted in the support rod. The support rod can support the drive rod and improve the stability of the drive rod when it rotates. Both the second bevel gear assembly and the first bevel gear assembly are tooth assemblies for power transmission disclosed in the prior art.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This invention uses a scraper to remove crystals and deposits from the inner wall of the tank. The connecting part allows the scraper to be connected to the rotating shaft when needed. The stirring shaft is in a separated state during stirring, which prevents the scraper from rotating with the stirring shaft during stirring. This prevents the scraper from constantly contacting and rubbing against the inner wall of the reactor, reducing wear between the scraper and the reactor and effectively improving the service life of the scraper.

[0018] This invention, through the inclusion of a crushing component, can break up a large number of methanol bubbles in a high-temperature, low-concentration hydrochloric acid liquid, allowing methanol to mix more thoroughly with the high-temperature, low-concentration hydrochloric acid and effectively improving the mixing reaction rate of methanol and high-temperature, low-concentration hydrochloric acid.

Example

[0034] Please refer to Figures 1-2 as well as Figures 8-9A chloromethane manufacturing apparatus includes a tank 1, a crushing component 6, a scraping component 4, and a connecting component 5. The tank 1 is equipped with a stirring motor 2, and a rotating shaft 3 is connected to the output shaft of the stirring motor 2. A stirring rod 7 for stirring and mixing is mounted on the rotating shaft 3. The crushing component 6 is located inside the tank 1 and connected to the rotating shaft 3. The crushing component 6 is used to crush air bubbles in the liquid. The scraping component 4 is movably located inside the tank 1 and is used to scrape away crystals from the inner wall of the tank 1. The connecting component 5 is located on the rotating shaft 3 and includes a movable plate 53 and a lower housing. The movable plate 53 and the lower housing can be connected by an insertion joint. The movable plate 53 and the lower housing are used for the transmission connection and transmission separation between the scraping component 4 and the rotating shaft 3.

[0035] The crushing component 6 also includes a second protective shell 61, a drive rod 63, and a support rod 66. One end of the drive rod 63 is provided with a rotating plate 64, and the inner side of the rotating plate 64 is provided with multiple crushing plates 65. The second protective shell 61 is rotatably located below the centrifugal impeller 8. The second protective shell 61 is provided with a second conical tooth group 62. When methanol from the top of the tank 1 is drawn into the high-temperature, low-concentration hydrochloric acid liquid through the centrifugal impeller 8, a large number of methanol bubbles will be formed in the high-temperature, low-concentration hydrochloric acid. The crushing component 6 can break up the large number of bubbles blown out, so that the methanol can be more fully mixed with the high-temperature, low-concentration hydrochloric acid.

[0036] The second bevel gear assembly 62 is connected to the drive rod 63 via a rotating rod 32. The end of the drive rod 63 away from the second bevel gear assembly 62 is connected to a support rod 66. The lower end of the support rod 66 is connected to the tank body 1. One end of the drive rod 63 is rotatably mounted in the support rod 66. The support rod 66 can support the drive rod 63 and improve the stability of the drive rod 63 when it rotates. Both the second bevel gear assembly 62 and the first bevel gear assembly 510 are gear assemblies for power transmission disclosed in the prior art.

[0037] In use, after methanol and high-temperature, low-concentration hydrochloric acid are introduced into tank 1, the stirring motor 2 is started to mix them. The stirring motor 2 drives the rotating shaft 3 to rotate, which in turn drives the stirring rod 7 to rotate, thus mixing and stirring the methanol and high-temperature, low-concentration hydrochloric acid. The rotating shaft 3 drives the centrifugal impeller 8 to rotate as well. The rotation of the centrifugal impeller 8 generates suction, which draws the methanol above tank 1 into the cavity of the rotating shaft 3 through the suction port, and then blows it out from the centrifugal impeller 8, so that the methanol above tank 1 can be transported to the high-temperature, low-concentration hydrochloric acid liquid for thorough mixing. When the rotating shaft 3 rotates, it also drives the bevel gear assembly 62 to operate synchronously. The bevel gear assembly 62 drives the drive rod 63 to rotate, which in turn drives the rotating plate 64 to rotate. The multiple breaking plates 65 on the rotating plate 64 rotate, which breaks the methanol bubbles transported to the high-temperature, low-concentration hydrochloric acid, thereby effectively improving the mixing speed between methanol and high-temperature, low-concentration hydrochloric acid and realizing a rapid mixing reaction between methanol and high-temperature, low-concentration hydrochloric acid.

[0038] Please refer to Figures 3-7 The rotating shaft 3 is composed of an upper rotating rod 31 and a lower rotating rod 32. A centrifugal impeller 8 is provided on the lower rotating rod 32. Both the lower rotating rod 32 and the upper rotating rod 31 have cavities. The cavities between the upper rotating rod 31 and the lower rotating rod 32 are connected by a connector 5. An air intake hole is provided on the upper rotating rod 31 and is connected to the cavity of the upper rotating rod 31. The cavity inside the lower rotating rod 32 is connected to the suction end of the centrifugal impeller 8. The upper rotating rod 31 and the lower rotating rod 32 are connected by a combined rod 33. When the rotating shaft 3 drives the impeller to rotate, the centrifugal impeller 8 can generate suction force and draw methanol from above the tank 1 into the cavity of the rotating shaft 3 through the air intake hole, so that the methanol gas can be transported to the high-temperature, low-concentration hydrochloric acid for thorough mixing.

[0039] The connecting component 5 includes a protective shell 51, a movable plate 53, and a control component. The protective shell 51 consists of an upper shell and a lower shell. The upper shell is located outside the upper rotating rod 31 and is fixedly connected to it. The upper shell is rotatably connected to the lower rotating rod 32. The movable plate 53 is movably installed in the upper shell. The movable plate 53 is equipped with a screw 56. The screw 56 is equipped with a gear 55. The gear 55 is rotatably installed in the upper shell and is meshed with a gear ring 57. Through the connecting component 5, the scraper 4 can be connected to the rotating shaft 3 for transmission when needed. This can prevent the scraper 41 from rotating together with the stirring shaft when stirring, prevent the scraper 41 from constantly contacting and rubbing against the inner wall of the reactor, reduce the wear between the scraper 41 and the reactor, and prevent gaps from easily forming between the scraper 41 and the reactor, which would affect the cleaning effect of the scraper 41 on the inner wall of the reactor.

[0040] The upper housing is provided with a fixed plate 54, and a rotating end protrudes from the gear 55. The gear 55 is rotatably connected to the fixed plate 54 through the rotating end. The gear 55 is threadedly connected to the screw 56. Through the threaded engagement between the screw 56 and the gear 55, the rotation of the gear 55 can drive the screw 56 to move linearly up and down, thereby driving the moving plate 53 to move linearly up and down.

[0041] The lower housing has multiple snap-fit ​​ends 52 equidistantly arranged above and below the moving plate 53. The ends of the snap-fit ​​ends 52 on the lower housing and the moving plate 53 are inclined on both sides. The inclined surfaces allow the snap-fit ​​ends 52 on the moving plate 53 to be inserted into the gaps between the snap-fit ​​ends 52 on the lower housing when the moving plate 53 moves downward, thus realizing the plug-in connection between the moving plate 53 and the lower housing. When the moving plate 53 rotates with the rotating shaft 3, it can drive the lower housing to rotate together, which in turn drives the scraper 4 to rotate and scrape and clean the inner wall of the tank 1.

[0042] The gear ring 57 has protruding connecting ends on both the upper and lower sides. The two connecting ends on the gear ring 57 are rotatably connected to the ends of the upper rotating rod 31 and the lower rotating rod 32, respectively. The lower rotating rod 32 has a limiting end 321 on its outer side. The moving plate 53 is movably located on the outer side of the lower rotating rod 32. The moving plate 53 has a limiting groove corresponding to the limiting end 321. The two connecting ends on the gear ring 57 are rotatably connected to the upper rotating rod 31 and the lower rotating rod 32 through sealed bearings. The sealed bearings have good sealing performance, so that the cavity in the upper rotating rod 31 and the cavity in the lower rotating rod 32 can be sealed and connected.

[0043] The scraping component 4 includes a scraper 41, with a connecting rod 42 on the inner side of the scraper 41. The connecting rod 42 is connected to the outer side of the lower shell. The scraper 41 is in contact with the inner wall of the tank 1. When the tank 1 needs to be cleaned after the reaction of chloromethane is completed, the inner wall of the tank 1 can be scraped and cleaned by rotating the scraper 41.

[0044] The control component includes a rotating rod 59, with a connecting rod 58 at one end. The connecting rod 58 is connected to the inner side of the gear ring 57. The other end of the connecting rod 58 is connected to a rotating rod 511 via a bevel gear set 510. One end of the rotating rod 511 passes through the outer side of the upper rotating rod 31. A rotating block 512 is provided at the outer end of the rotating rod 511. The rotating rod 59 is rotatably disposed in the cavity of the upper rotating rod 31. The control component can transmit power to control the up and down movement of the moving plate 53 on the drive connecting component 5.

[0045] After the reaction is complete, when cleaning is required inside tank 1, rotating block 512 is rotated. Rotating block 512 drives rotating rod 511 to rotate, which in turn drives bevel gear assembly 510 to run. Bevel gear assembly 510 drives rotating rod 59 to rotate. Rotating rod 59 drives gear ring 57 to rotate via connecting rod 58. Gear ring 57 drives gear 55 to rotate, causing screw 56 to move downward. Screw 56 drives moving plate 53 to move downward, so that the snap-fit ​​end 52 on moving plate 53 can be inserted into the gap between snap-fit ​​end 52 on lower shell, so that lower shell and moving plate... When the 53 parts are connected together, and the stirring motor 2 is started, the rotating shaft 3 rotates and drives the lower shell to rotate. Then, the connecting rod 42 drives the scraper 41 to rotate, so that the scraper 41 can scrape and clean the crystals on the inner wall of the tank 1. By driving the scraper 41 to rotate and clean only when the tank 1 needs to be cleaned, the scraper 41 can be prevented from rotating together with the stirring shaft when it is stirring. This prevents the scraper 41 from constantly contacting and rubbing against the inner wall of the reactor, reducing the wear between the scraper 41 and the reactor, and effectively improving the use effect and service life of the scraper 41.

[0046] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations of the embodiments of the present invention may be made without departing from the stated principles.
