[0039] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0040] Please refer to Figures 1-9 , which shows a schematic structural diagram of an embodiment of a photocatalytic reaction device for the production of chlorinated paraffin of the present invention. Please refer to Figures 1-9 , and a detailed introduction to a photocatalytic reaction device for the production of chlorinated paraffin will be given.

[0041] Example 1: A photocatalytic reaction device for the production of chlorinated paraffin, comprising a reaction barrel 100, a stirring mechanism 200, a crushing mechanism 300, an irradiation mechanism 400, and a driving mechanism 500:

[0042] The reaction barrel 100 is in the shape of a barrel with an open top wall, and a top cover 101 is detachably installed at the top of the reaction barrel 100;

[0043] The stirring mechanism 200 is movably arranged on the bottom wall of the top cover 101 and is located in the inner cavity of the reaction barrel 100 for stirring the chlorinated paraffin solvent and the photocatalyst. The stirring mechanism 200 includes a vertical connecting rod 201 rotatably arranged at the center of the bottom of the top cover 101 through a bearing;

[0044] The crushing mechanism 300 is movably arranged at the bottom of the inner cavity of the reaction barrel 100 and is located below the stirring mechanism 200 for crushing the sediment inside the reaction barrel 100. The crushing mechanism 300 includes a vertical rotating cylinder 302 rotatably penetrating through the center of the bottom wall of the reaction barrel 100 through a first sealing bearing 301. The rotating cylinder 302 is a hollow tubular shape with upper and lower ends communicating. A vertical rotating rod 306 is rotatably arranged through the inner side of the rotating cylinder 302 through a second sealing bearing 305. By providing the first sealing bearing 301 and the second sealing bearing 305, the leakage of the solution is appropriately avoided. The bottom end of the connecting rod 201 is detachably connected to the top end of the rotating rod 306. The rotating cylinder 302 and the rotating rod 306 rotate in opposite directions, and a crushing device for crushing the sediment is arranged on the outer side;

[0045] The irradiation mechanism 400 is arranged inside the reaction barrel 100 and is used to irradiate the solution. The irradiation mechanism 400 includes a lifting ring 401 that reciprocates up and down through a reciprocating lead screw 404. A circle of ultraviolet irradiation lamps 402 is arranged inside the lifting ring 401. It should be noted that the ultraviolet irradiation lamp 402 includes a light-emitting lamp bead and a transparent cover. The transparent cover is installed inside the ultraviolet irradiation lamp 402, and a sealing ring is arranged at the installation position.

[0046] The driving mechanism 500 is used to drive the stirring mechanism 200 to stir the solution, drive the crushing mechanism 300 to crush the sediment inside the reaction barrel 100, and simultaneously drive the lifting ring 401 to reciprocate up and down to irradiate the solution through the ultraviolet irradiation lamp 402.

[0047] Furthermore, a drain pipe 102 communicating with the inner cavity of the reaction barrel 100 is arranged at the bottom of the side wall of the reaction barrel 100. A drain valve 103 is arranged on the drain pipe 102. The bottom of the inner cavity of the reaction barrel 100 is inclined and gradually becomes lower towards the position where the drain pipe 102 is located. The inclination angle is about 5°, so that the solution can be better discharged from the inner cavity of the reaction barrel 100 along the inclined bottom surface.

[0048] Embodiment 2, based on Embodiment 1: A central fixed gear 202 is fixedly arranged at the central position of the bottom of the top cover 101. The rod body of the connecting rod 201 rotatably penetrates through the center of the central fixed gear 202. An "L-shaped" mounting plate 203 is fixedly arranged on the rod body of the connecting rod 201. The mounting plate 203 is spaced below the central fixed gear 202. Vertically arranged first rotating shafts 204 are rotatably penetrated through the three top corners of the mounting plate 203 close to itself through bearing sleeves. The three first rotating shafts 204 are arranged equidistantly around the central fixed gear 202. A planetary gear 205 that meshes with the central fixed gear 202 is fixedly arranged at the upper end of each first rotating shaft 204. A follower gear 206 is fixedly arranged at the lower end of each first rotating shaft 204. Vertically arranged second rotating shafts 207 are rotatably arranged at the bottom of the mounting plate 203 close to each follower gear 206. Transmission gears 208 are arranged on the rod bodies of the three second rotating shafts 207. The three transmission gears 208 mesh with the follower gears 206 close to them. A strip-shaped plate 209 is fixedly arranged at the lower end of each second rotating shaft 207 and is connected to one end of the strip-shaped plate 209. A vertical stirring shaft 210 is fixedly arranged at the other end of the strip-shaped plate 209. Stirring blades 211 are fixedly installed equidistantly around the rod body of each stirring shaft 210. When the connecting rod 201 rotates, the entire mounting plate 203 can be driven to rotate. At this time, all the stirring blades 211 as a whole can be driven to rotate, thereby stirring the solution. When the mounting plate 203 rotates, since the central fixed gear 202 is fixedly installed and cannot rotate, the planetary gear 205 rotates around the central fixed gear 202, thereby driving the first rotating shaft 204 and the follower gear 206 to rotate. Then, the second rotating shaft 207 is driven to rotate through the transmission gear 208, so that the stirring shaft 210 and the stirring blades 211 at the other end of the strip-shaped plate 209 rotate around the second rotating shaft 207, that is, the three groups of stirring blades 211 can be separately driven to rotate around the second rotating shaft 207, thereby further stirring the solution and improving the stirring effect;

[0049] The rotating stirring blades 211 always keep a distance from the outer side of the ultraviolet irradiation lamp 402 and the rod body of the connecting rod 201; it is ensured that when the stirring blades 211 rotate, they will not collide with any components, which is beneficial to the stable operation of the device;

[0050] Further, the inner sidewall of the reaction barrel 100 and the outer surface of each stirring blade 211 are smooth, and a reflective layer is provided on both the inner sidewall of the reaction barrel 100 and the outer surface of the stirring blade 211; by providing a reflective layer on the inner sidewall of the smooth reaction barrel 100 and the outer surface of the stirring blade 211, the light irradiated by the ultraviolet irradiation lamp 402 can be reflected multiple times inside the reaction barrel 100 through the reflective layer, so as to make more full use of the irradiated energy, which is beneficial to the sufficient irradiation of the solution and improves the photocatalytic efficiency.

[0051] Example 3, based on Example 1: The crushing device includes first mounting strips 303 fixedly arranged in an equally spaced surrounding manner with the vertical axis of the rotating cylinder 302 as the center, and first crushing nails 304 are arranged at intervals along the length direction of the side wall of each first mounting strip 303;

[0052] Second mounting strips 307 are fixedly arranged in an equally spaced surrounding manner with the axis of the rod body of the rotating rod 306 as the center, and second crushing nails 308 are arranged at intervals along the length direction of the side wall of each second mounting strip 307;

[0053] The first mounting strips 303 and the second mounting strips 307 are respectively located in the inner cavity of the reaction barrel 100 and are arranged in an alternating manner, and the movable first crushing nails 304 and second crushing nails 308 are always kept at a distance from the outside of the ultraviolet irradiation lamp 402; it is ensured that when the first crushing nails 304 and the second crushing nails 308 of the components move, they will not collide with any components, which is beneficial to the stable operation of the device;

[0054] Further, a vertical spline rod 309 is fixedly arranged at the top end of the rotating rod 306, and a vertical spline slot hole 310 adapted to fit and insert the spline rod 309 is opened at the center of the bottom of the connecting rod 201. When the rotating rod 306 rotates, the connecting rod 201 can be driven to rotate accordingly through the spline rod 309 and the spline slot hole 310. A handle 104 and a lid lock are fixedly arranged at the top of the top cover 101; the lid lock is not shown in the figure, and its main function is to lock the top cover 101 on the top of the reaction barrel 100, so that the connection and rotation of the connecting rod 201 and the spline slot hole 310 are more stable. Moreover, when it is necessary to input the solution or after the photocatalysis is completed, the lid lock can be opened, and the top cover 101 and the stirring mechanism 200 can be vertically taken out of the inner cavity of the reaction barrel 100 through the handle 104. At this time, the spline rod 309 is separated from the spline slot hole 310, and the inside of the reaction barrel 100 can be cleaned more conveniently. During the photocatalytic reaction, by providing the top cover 101, the leakage of ultraviolet rays can be reduced to cause harm to the operator.

[0055] Embodiment 4, based on Embodiment 1: The irradiation mechanism 400 further includes fixing blocks 403 fixed to the tops of both sides inside the reaction barrel 100. The vertical reciprocating lead screw 404 rotates at the bottom of the fixing block 403 on the right through a bearing. A vertical limit guide rod 405 is fixedly arranged at the bottom of the fixing block 403 on the left. The rod body of the limit guide rod 405 slidably penetrates through the lifting ring 401 through a linear bearing 406. The rod body of the reciprocating lead screw 404 movably penetrates through the lifting ring 401, and the rotating reciprocating lead screw 404 drives the lifting ring 401 to reciprocally lift along the rod body of the limit guide rod 405. The reciprocally lifting and lowering lifting ring 401 can expand the range irradiated by the ultraviolet irradiation lamp 402. In existing devices, multiple layers of ultraviolet irradiation lamps are usually installed around the inner side wall of the component in a surrounding manner. Although the irradiation efficiency is relatively high, a large number of ultraviolet irradiation lamps need to be installed. In this embodiment, different from the traditional device with multiple layers of fixedly installed ultraviolet irradiation lamps, by expanding the irradiation range, while reducing the number of lamps, the irradiation efficiency can be better guaranteed.

[0056] Further, an annular cleaning scraping ring 407 is arranged on the outer side of the lifting ring 401, and the outer side wall of the cleaning scraping ring 407 is attached to the inner side wall of the reaction barrel 100. When it is necessary to clean the inside of the reaction barrel 100, a cleaning liquid can be injected into the reaction barrel 100, and then the locking top cover 101 is closed. At this time, the connecting rod 201 and the rotating rod 306 are assembled, and then the device is started. By controlling the reciprocating lifting and lowering of the lifting ring 401, the inner side wall of the reaction barrel 100 can be cleaned by the cleaning scraping ring 407, and the rotating stirring blade 211 can also assist in increasing the flow of the cleaning liquid, thereby facilitating the flushing of the inner side wall of the reaction barrel 100. It should be noted that in this embodiment, only the inner side wall of the reaction barrel 100 is assisted in cleaning. If a thorough cleaning is required, the top cover 101 can be opened, and other methods can be used to perform a deeper cleaning of the inside of the reaction barrel 100.

[0057] Embodiment 5, based on Embodiment 1: The driving mechanism 500 includes a hollow base 501 fixed to the bottom of the reaction barrel 100. A horizontal servo motor 502 is fixedly arranged at the left side of the inner cavity bottom of the base 501. The output end of the servo motor 502 is fixedly connected with a first bevel gear 503 through a coupling. The outer side of the lower end of the rod body of the rotary drum 302 is located in the base 501 and is provided with a second bevel gear 504 meshing with the first bevel gear 503. The outer side of the lower end of the rod body of the rotating rod 306 is located in the base 501 and is provided with a third bevel gear 505 meshing with the first bevel gear 503. When the servo motor 502 is started, it drives the first bevel gear 503 to rotate, so that the second bevel gear 504 and the third bevel gear 505 drive the rotary drum 302 and the rotating rod 306 to rotate in opposite directions at the same time, so that the first crushing nails 304 and the second crushing nails 308 move in opposite directions at the same time, generating destructive forces in two directions on the internal sediment, which is beneficial to crushing the sediment.

[0058] Further, the driving mechanism 500 further includes a fixing frame 506 fixed to the right side of the inner cavity bottom of the base 501. A horizontal transmission rod 507 is rotatably penetrated through the side wall of the fixing frame 506 through a bearing. A fourth bevel gear 508 meshing with the second bevel gear 504 and the third bevel gear 505 is fixedly arranged at the left end of the transmission rod 507. A fifth bevel gear 509 is fixedly arranged at the right end of the transmission rod 507. The lower end of the reciprocating lead screw 404 is rotatably penetrated through the bottom of the reaction barrel 100 through a third sealing bearing 408, and a sixth bevel gear 510 meshing with the fifth bevel gear 509 is fixedly arranged at the lower end of the reciprocating lead screw 404. When the second bevel gear 504 and the third bevel gear 505 rotate, the transmission rod 507 is driven to rotate through the fourth bevel gear 508, and then the reciprocating lead screw 404 can be driven to rotate simultaneously through the fifth bevel gear 509 and the sixth bevel gear 510, so as to realize the simultaneous movement of multiple components.
