[0001] The present invention relates to the technical field of feeding equipment, and particularly to a reactor feeding equipment capable of controlling the feeding speed. Background Art

[0002] A reactor is a device for realizing a reaction process, which is widely used in the fields of chemical industry, oil refining, metallurgy, etc. Reactors are used to realize liquid-phase single-phase reaction processes and multi-phase reaction processes such as liquid-liquid, gas-liquid, liquid-solid, and gas-liquid-solid. In the chemical reaction process, feeding equipment is needed to feed the reactor for the reaction.

[0003] At present, most of the existing reactor feeding equipment has significant deficiencies in speed control and anti-blocking of materials: traditional speed control methods mostly use a single valve or a horizontal baffle structure, with low adjustment accuracy and easy to cause blockage due to raw material residues, and frequent leakage problems; the stirring device often relies on a rotary design, with a single movement trajectory, unable to break the static accumulation or caking of raw materials, resulting in low feeding efficiency and high energy consumption; in addition, the speed control and stirring functions need to be driven by independent driving equipment, resulting in a complex equipment structure, large occupied space and superposition of energy consumption.

The bottom end of the telescopic rod B is connected to an activity frame;

[0008] A driving mechanism is arranged at the top end of the feeding hopper. The driving mechanism includes a worm rotatably connected to the feeding hopper through a bearing and a worm gear welded to the guide frame. Moving gears are movably connected to the front and rear ends of the worm. A fixed gear welded to the rotating rod is meshed and connected to the bottom end of the moving gear.

[0009] Preferably, support blocks connected to the speed control plate through pin holes are welded to both the front and rear ends of the feeding hopper, and support rods that form a sliding structure with the support frame are symmetrically welded to the side of the speed control plate away from the support blocks.

[0010] Preferably, storage grooves are symmetrically formed inside the speed control plate, pin shafts that form a sliding structure are welded to one end of the side baffle close to the storage groove, and guiding grooves for storing and guiding the side baffle are symmetrically formed at the bottom end of the feeding hopper.

[0011] Preferably, spiral grooves are formed on the surface of the rotating rod, guiding blocks that form a sliding structure with the spiral grooves are arranged inside the lifting frame, and guiding plates for limiting and guiding the lifting frame are welded to both the front and rear ends of the feeding hopper.

[0013] Preferably, a driving motor connected to the worm through a coupling is installed inside the mounting frame at the front end of the feeding hopper, and an activity groove for slidably connecting with the moving gear is formed inside the worm.

[0014] Preferably, a push-pull plate is slidably connected to one side of the worm, an electric push rod is installed between the push-pull plate and the worm, and a linkage rope passing through the activity groove is connected between the two moving gears and the push-pull plate.

[0015] Preferably, a disc is arranged on the outer side of the worm, and a return spring is connected between the disc and the moving gear.

[0016] Preferably, a locking mechanism is connected between the worm, the feeding hopper, and the fixed gear. The locking mechanism includes a chuck connected to the bottom end of the fixed gear, a clamping frame is snap-fitted to one side of the chuck, and a support spring is connected between the clamping frame and the feeding hopper.

[0017] Preferably, annular inclined surface frames are arranged at the ends of the two moving gears close to each other, an inclined surface block that fits with the annular inclined surface frame is arranged at the end of the clamping frame away from the chuck, and a ball for reducing friction is rotatably connected to the groove at the bottom end of the inclined surface block.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. For the feeding equipment of this reactor, when the moving gear and the fixed gear are in the meshed state, the speed control plate is deflected through the lifting frame and the support frame in the speed control mechanism, so as to adjust the distance between the speed control plates. Moreover, the smaller the distance, the lower the flow rate. At the same time, the side baffle moves longitudinally, so as to block the gaps between the front and rear ends of the speed control plate and the feeding hopper, prevent material leakage, and ensure the accuracy of speed control.

[0020] 2. For the feeding equipment of this reactor, when the moving gear and the fixed gear are in the separated state, the raw materials are made to have a combined axial and radial flow through the moving mechanism, preventing blockage caused by static accumulation of the raw materials, so as to improve the discharging effect and efficiency of the raw materials. At the same time, the moving frame impacts and breaks up the caked raw materials, preventing the caked raw materials from affecting the mixing effect after feeding.

[0021] 3. For the feeding equipment of this reactor, when the electric push rod works and extends, the moving gear and the fixed gear are separated. When the electric push rod works and contracts, the moving gear and the fixed gear are meshed, thereby driving the moving mechanism and the speed control mechanism to operate. And a single driving motor can complete the synchronous control of the moving mechanism and the speed control mechanism and the independent control of the moving mechanism, not only making the feeding equipment structure compact, but also significantly reducing energy consumption.

[0022] 4. For the feeding equipment of this reactor, during the process of the separation of the moving gear and the fixed gear, the clamping frame and the chuck automatically engage, so that the fixed gear can be stably locked in the non-working state, ensuring that the speed control mechanism remains absolutely stationary, thereby greatly improving the operation stability of the reactor feeding equipment. When the moving gear and the fixed gear are meshed, the clamping frame will separate from the chuck, so as to prevent affecting the drive of the speed control mechanism.

Detailed implementation manners

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] Please refer to Figures 1 - 4 , the present invention provides a technical solution: a reactor feeding device capable of controlling the feeding speed, including a feeding hopper 1 for feeding materials into the reactor;

[0039] Refer to Figures 1 - 7 It can be seen that a speed control mechanism 2 is arranged on the outer side of the bottom end of the feeding hopper 1. The speed control mechanism 2 includes a speed control plate 202, side baffles 210 movably connected to the feeding hopper 1, and a rotating rod 206 rotatably connected to the feeding hopper 1. Support blocks 201 welded to the front and rear ends of the feeding hopper 1 and connected to the speed control plate 202 through pin holes. Receiving grooves 209 are symmetrically formed inside the speed control plate 202. A pin shaft 211 forming a sliding structure is welded to one end of the side baffle 210 close to the receiving groove 209. Guide grooves 212 for receiving and guiding the side baffle 210 are symmetrically formed at the bottom end of the feeding hopper 1. A lifting frame 205 is movably connected to the outer side of the rotating rod 206, and a support frame 204 movably connected to the speed control plate 202 is welded to the bottom end of the lifting frame 205. Support rods 203 forming a sliding structure with the support frame 204 are symmetrically welded to one side of the speed control plate 202 away from the support block 201. A spiral groove 207 is formed on the surface of the rotating rod 206. A guide block 208 forming a sliding structure with the spiral groove 207 is arranged inside the lifting frame 205. Guide plates 6 for limiting and guiding the lifting frame 205 are welded to the front and rear ends of the feeding hopper 1, so as to prevent the lifting frame 205 from tilting and shifting;

[0040] Refer to Figures 1 - 7 and Figure 13 It can be seen that when the moving gear 404 and the fixed gear 405 are in the meshing state and the driving motor 401 is working, the output end of the driving motor 401 drives the worm 402, the moving gear 404, the fixed gear 405 and the rotating rod 206 to rotate. Since the lifting frame 205 and the rotating rod 206 are slidably connected through the spiral groove 207 and the guide block 208, the lifting frame 205 and the support frame 204 make a longitudinal rapid movement. Since the speed control plate 202 and the support frame 204 are slidably connected through the support rod 203 and rotatably connected to the feeding hopper 1 through the support block 201, the speed control plate 202 makes a deflection with the support block 201 as the axis, so as to realize the adjustment of the distance between the speed control plates 202, and the smaller the distance, the lower the flow rate. When it is completely closed, the feeding can be cut off. And the speed control operation is realized by deflecting the speed control plate 202, so that the feeding of the raw materials is relatively complete, and the raw materials are prevented from accumulating on the speed control plate 202 after feeding. Since the side baffle 210 and the speed control plate 202, the feeding hopper 1 are slidably connected through the pin shaft 211, the receiving groove 209 and the guide groove 212 respectively, the side baffle 210 moves longitudinally with the deflection of the speed control plate 202, so as to realize the sealing of the gaps between the front and rear ends of the speed control plate 202 and the feeding hopper 1, prevent material leakage, so as to ensure the accuracy of speed control. And the side baffle 210 and the speed control plate 202 are linked and adjusted through sliding / rotating connection, without an additional power source, simplifying the operation process and saving energy.

[0041] Refer to Figure 1 、 Figure 3 、Figure 8 and Figure 9 As can be seen, an actuating mechanism 3 is disposed through the inside of the charging hopper 1. The actuating mechanism 3 includes a guide rod A304 and a guide rod B308 welded to the charging hopper 1, and a guide frame 301 connected to the charging hopper 1 through a bearing. The guide rod A304 is located above the guide rod B308. A support frame 302 is slidably connected to the outside of the guide frame 301. The bottom ends of the guide frame 301 and the support frame 302 are respectively connected to a telescopic rod A305 and a telescopic rod B310. The bottom end of the telescopic rod B310 is connected to a movable frame 309. Guide members A303 that form a sliding structure with the guide rod A304 are connected to both sides of the support frame 302. A limiting plate 306 connected to the bottom end of the telescopic rod A305 is slidably connected to the inside of the movable frame 309. Guide members B307 that form a sliding structure with the guide rod B308 are disposed on both sides of the limiting plate 306;

[0042] Refer to Figure 1 、 Figure 3 、 Figure 8 and Figure 9 、 Figure 13 As can be seen, when the moving gear 404 and the fixed gear 405 are in a separated state and the driving motor 401 is operating, the output end of the driving motor 401 drives the worm 402, the worm gear 403, the guide frame 301, and the support frame 302 to rotate. Since the support frame 302 is slidably connected to the guide frame 301, and the guide member A303 is slidably connected to the guide rod A304, the support frame 302 makes a lateral reciprocating motion while rotating. Since the movable frame 309 is slidably connected to the limiting plate 306, and the guide member B307 is slidably connected to the guide rod B308, and the limiting plate 306 is telescopically connected to the guide frame 301 through the telescopic rod A305, and the movable frame 309 is telescopically connected to the support frame 302 through the telescopic rod B310, the support frame 302 makes a longitudinal reciprocating movement while rotating and moving laterally. Through the lateral / longitudinal reciprocating motion and rotation of the movable frame 309, a three-dimensional stirring track is formed, causing the raw materials to have an axial and radial composite flow, thereby preventing the raw materials from being blocked due to static accumulation, so as to improve the feeding effect and efficiency of the raw materials. Moreover, the alternating shear force generated by the lateral movement can destroy the static accumulation structure of the raw materials, causing the movable frame 309 to have an impact and fragmentation effect on the agglomerated raw materials, preventing the agglomerated raw materials from affecting the mixing effect after feeding. And compared with pure rotary stirring, the composite motion mode can reduce energy consumption under the same processing capacity, so as to achieve an energy-saving effect through the optimization of the motion track.

[0043] Refer to Figures 1 - 3 and Figure 10 、 Figure 11 、 Figure 13It can be seen that a driving mechanism 4 is provided at the top of the feeding hopper 1. The driving mechanism 4 includes a worm 402 connected to the feeding hopper 1 through a bearing and a worm wheel 403 welded to the guide frame 301. Moving gears 404 are movably connected to both the front and rear ends of the worm 402. A fixed gear 405 welded to the rotating rod 206 is meshed and connected to the bottom end of the moving gear 404. A driving motor 401 connected to the worm 402 through a coupling is installed in the mounting frame at the front end of the feeding hopper 1. An activity groove 408 slidably connected to the moving gear 404 is formed inside the worm 402, and the activity groove 408 is composed of a hole groove and straight-through grooves located at both ends of the hole groove. A push-pull plate 410 is slidably connected to one side of the worm 402. An electric push rod 411 is installed between the push-pull plate 410 and the worm 402. A linkage rope 409 passing through the activity groove 408 is connected between the two moving gears 404 and the push-pull plate 410. A disc 406 is provided on the outer side of the worm 402. A return spring 407 is connected between the disc 406 and the moving gear 404;

[0044] Refer to Figures 1 - 3 and Figure 10 、 Figure 11 、 Figure 13 It can be seen that since the moving gear 404 is slidably connected to the worm 402 through the activity groove 408, and the two moving gears 404 are linked with the push-pull plate 410 through the linkage rope 409, when the electric push rod 411 works and extends, the moving gear 404 can be horizontally moved and separated from the fixed gear 405. Since the moving gear 404 is elastically connected to the disc 406 through the return spring 407, when the electric push rod 411 works and contracts, the moving gear 404 will automatically reset under the action of the return spring 407 and mesh with the fixed gear 405, so as to facilitate the operation of the driving mechanism 3 and the speed control mechanism 2, and a single driving motor 401 can complete the synchronous control of the driving mechanism 3 and the speed control mechanism 2 and the independent control of the driving mechanism 3. This not only makes the feeding equipment structure compact, but also significantly reduces energy consumption.

[0045] Refer to Figures 1 - 3 and Figure 12 It can be seen that a locking mechanism 5 is connected between the worm 402, the feeding hopper 1 and the fixed gear 405. The locking mechanism 5 includes a chuck 504 connected to the bottom end of the fixed gear 405. A clamping frame 503 is clamped and connected to one side of the chuck 504. A support spring 505 is connected between the clamping frame 503 and the feeding hopper 1. Annular inclined surface frames 501 are provided at the ends of the two moving gears 404 close to each other. An inclined surface block 502 fitted to the annular inclined surface frame 501 is provided at the end of the clamping frame 503 away from the chuck 504. A ball for reducing friction is rotatably connected in the groove at the bottom end of the inclined surface block 502, so that the inclined surface block 502 will not hinder the rotation of the annular inclined surface frame 501;

[0046] Refer to Figures 1 - 3 andFigure 12 , Figure 13 It can be seen that since inclined planes are provided at the ends of the inclined plane block 502 and the annular inclined plane frame 501 that are close to each other, and the clamping frame 503 and the feeding hopper 1 are elastically connected by a support spring 505, during the separation process of the moving gear 404 and the fixed gear 405, the inclined plane block 502 can be pushed to move vertically upward by the annular inclined plane frame 501, so that the clamping frame 503 and the chuck 504 are automatically clamped. Through the high-precision clamping fit between the chuck 504 and the clamping frame 503, the fixed gear 405 can be stably locked in the non-working state, ensuring that the speed control mechanism 2 remains absolutely stationary, thus greatly improving the operating stability of the reactor feeding equipment. When the moving gear 404 and the fixed gear 405 are engaged, the clamping frame 503 will automatically reset and separate from the chuck 504 under the action of the support spring 505, thereby preventing the driving of the speed control mechanism 2 from being affected.

[0047] Working principle: When using the reactor feeding equipment with controllable feeding speed, the electric push rod 411 is operated to contract, so that the push-pull plate 410 releases the pulling of the linkage rope 409, and the moving gear 404 and the annular inclined plane frame 501 will automatically reset and engage with the fixed gear 405 under the action of the return spring 407. At the same time, the clamping frame 503 will automatically reset and separate from the chuck 504 under the action of the support spring 505 to release the locking of the fixed gear 405. At this time, the drive motor 401 is started, so that the output end of the drive motor 401 drives the worm 402, the moving gear 404, the fixed gear 405 and the rotating rod 206 to rotate. Through the sliding action between the lifting frame 205 and the rotating rod 206, the lifting frame 205 and the support frame 204 make a rapid longitudinal movement. Through the sliding action between the speed control plate 202 and the support frame 204 and the rotating action with the feeding hopper 1, the speed control plate 202 deflects around the support block 201, thereby realizing the adjustment of the distance between the speed control plates 202. The greater the distance, the higher the flow rate. At the same time, through the sliding action between the side baffle 210 and the speed control plate 202 and the feeding hopper 1, the side baffle 210 moves longitudinally with the deflection of the speed control plate 202, thereby realizing the sealing of the gaps between the front and rear ends of the speed control plate 202 and the feeding hopper 1. At this time, the electric push rod 411 is operated to extend, so that the moving gear 404 moves horizontally and separates from the fixed gear 405. Then the raw materials are put into and stored in the feeding hopper 1, and the feeding hopper 1 is located above the reactor. The stored raw materials are fed into the reactor at a fixed time and quantity for the reaction;

[0048] In this process, the output end of the driving motor 401 drives the worm 402, the worm wheel 403, the guide frame 301, and the support frame 302 to rotate. Through the sliding actions of the support frame 302 with the guide frame 301, and the guide member A303 with the guide rod A304, the support frame 302 makes a lateral reciprocating motion while rotating. Through the sliding actions of the movable frame 309 with the limit plate 306, and the guide member B307 with the guide rod B308, the support frame 302 makes a longitudinal reciprocating movement while rotating and moving laterally, so as to form a three-dimensional stirring trajectory, causing the raw materials to have an axial and radial composite flow, thereby preventing the raw materials from being blocked due to static accumulation, and having an impact and fragmentation effect on the agglomerated raw materials, preventing the agglomerated raw materials from affecting the mixing reaction effect after feeding. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0049] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
