Description

Technical Field

[0001] The present application relates to the field of chemical equipment, and in particular to a reactor with an automatic catalyst dosing function. Background Art

[0002] When the reactor is stirring materials, a catalyst needs to be added into the reactor at a specific time period to improve the chemical reaction efficiency of the materials inside the reactor.

[0003] At present, the operation of adding catalyst to the reactor is mostly completed manually. Specifically, the operator carries the bagged catalyst to the feed port on the top of the reactor, unpacks the bagged catalyst, and pours the bagged catalyst into the reactor body to complete the catalyst addition operation.

[0004] With regard to the above-mentioned related technologies, the above-mentioned catalyst addition operation process usually requires the cooperation of multiple operators to complete, and the overall operation efficiency is low. In addition, since the feed port of the reactor is located at a higher position of the reactor body, when the operator adds the catalyst, he usually needs to climb to the feed port of the reactor body with the help of tools such as ladders to complete the pouring of the catalyst, which is inconvenient to operate; therefore, there is room for improvement. Summary of the invention

[0005] In order to facilitate the addition of the catalyst into the reactor, the present application provides a reactor with an automatic catalyst addition function.

[0006] The present application provides a reactor with a catalyst automatic dosing function, which adopts the following technical solution: A reactor with a catalyst automatic dosing function, comprising a reactor body, a storage part, a conveying mechanism, a collecting part and a grabbing mechanism; The storage portion is used for stacking bagged catalysts; The conveying mechanism comprises a hopper, the bottom of the hopper is connected to a screw conveyor, the output end of the screw conveyor extends to above the feed inlet of the reactor body; the top of the hopper is also provided with a bag cutting assembly for cutting the bag body of the bagged catalyst; The collecting part is used to store the bagged catalyst; The grabbing mechanism is used to grab the bagged catalyst at the storage portion and move it to the bag cutting assembly of the hopper, and the grabbing mechanism is also used to move the bag body of the bagged catalyst from the bag cutting assembly to the collecting portion.

[0007] By adopting the above technical scheme, the bagged catalyst located at the storage part is grabbed by the grabbing mechanism and moved to the bag cutting assembly located above the hopper, and the bag cutting assembly is used to cut an incision at the bottom of the bag body of the bagged catalyst to allow the catalyst in the bagged catalyst to fall into the hopper through the incision. The catalyst falling into the hopper is transported upward by the screw conveyor at the bottom of the hopper, and discharged into the feed hopper of the reactor body through the output end of the screw conveyor, thereby realizing the automatic delivery of the catalyst to the reactor body, and the remaining bags are transferred by the grabbing mechanism and placed in the collection box; compared with the traditional operation method of manually delivering the catalyst, the overall operation efficiency is effectively improved, and no manual intervention is required throughout the process, making the delivery of the catalyst to the reactor simpler and more convenient.

[0008] Preferably, the bag cutting assembly includes a rodless cylinder and a cutter, the cutter is connected to a slide of the rodless cylinder, and the cutter is arranged vertically upward.

[0009] By adopting the above technical solution, after the grabbing mechanism moves the bagged catalyst to the top of the cutter, it continues to move the bagged catalyst downward until the cutter is inserted into the bottom of the bag of the bagged catalyst. The rodless cylinder drives the cutter to slide in the horizontal direction, and the cutter can be used to cut the bottom of the bag of the bagged catalyst to form an incision for the catalyst to flow out.

[0010] Preferably, tensioning assemblies are provided on opposite sides of the rodless cylinder, and the tensioning assemblies include a tensioning support, an adsorption portion, a first lifting drive member and a first sliding drive member, and the adsorption portion is located above the tensioning support; the adsorption portion includes a support plate, and a plurality of tensioning suction cups are vertically installed on the support plate; the first lifting drive member is installed on the tensioning support and the first lifting drive member is drivingly connected to the support plate, and is used to drive the support plate to be lifted and lowered vertically; the first sliding drive member is drivingly connected to the tensioning support, and is used to drive the tensioning support to move horizontally in a direction close to or away from the rodless cylinder.

[0011] By adopting the above-mentioned technical scheme, through the setting of the tensioning component, after the subsequent grasping mechanism grasps and moves the bagged catalyst and inserts the cutter into the bottom of the bag body of the bagged catalyst, the first lifting drive member on the tensioning support drives the adsorption part to move upward, and the bottom of the bag body of the bagged catalyst is adsorbed and fixed by the adsorption suction cup on the adsorption part, and then the first sliding drive member drives the tensioning support to move in the direction away from the rodless cylinder, so that the bottom of the bag body of the bagged catalyst is tensioned, which is conducive to making it easier to cut the bottom of the bag body of the bagged catalyst when the subsequent cutter slides; at the same time, after the cutter is driven by the rodless cylinder to slide the bottom of the bag body of the bagged catalyst, the first sliding drive member can be used to drive the support to drive the tensioning suction cup to move further in the direction away from the rodless cylinder, so that the incision at the bottom of the bag body of the bagged catalyst is further enlarged at this time, which is conducive to the catalyst of the bagged catalyst being discharged from the bottom opening of the bag body more quickly.

[0012] Preferably, the grabbing mechanism comprises a manipulator and a grabbing part, and the grabbing part is used to grab the bagged catalyst.

[0013] By adopting the above technical solution, the bagged catalyst is moved to the hopper, collection box and other locations through the cooperation of the manipulator and the grabbing part, making the transportation and movement of the bagged catalyst simpler and more convenient.

[0014] Preferably, the grasping portion includes a connecting seat, the connecting seat is connected to the driving end of the manipulator, and a sponge suction cup is installed on the connecting seat.

[0015] By adopting the above technical solution, the manipulator drives the connecting seat to drive the sponge suction cup to move above the target bagged catalyst, and then the sponge suction cup adsorbs and fixes the surface of the target bagged catalyst to complete the grabbing of the bagged catalyst. Subsequently, the manipulator cooperates with the sponge suction cup to move the bag of the bagged catalyst to above the collection box, and the sponge suction cup releases the adsorption of the bag of the bagged catalyst, so that the bag of the bagged catalyst can fall into the collection box.

[0016] Preferably, blowing parts are provided on both opposite sides of the connecting seat, and the blowing parts are arranged toward the adsorption station of the sponge suction cup; the blowing part includes a blowing bracket, and the blowing bracket supports a plurality of blowing pipes on one side of the sponge suction cup adsorption station, and the blowing bracket is provided with a plurality of second sliding driving parts corresponding to the plurality of blowing pipes, and the second sliding driving parts are drivingly connected to the corresponding blowing pipes, and are used for driving the corresponding blowing pipes to move in a horizontal direction toward or away from the sponge suction cup adsorption station.

[0017] By adopting the above technical solution, after the manipulator cooperates with the sponge suction cup to grab the bagged catalyst, the second sliding drive member on the blowing bracket drives the corresponding air outlet pipe to move toward the adsorption station close to the sponge suction cup until the blowing pipe is inserted into the bagged catalyst adsorbed by the sponge suction cup; while the catalyst inside the bagged catalyst falls out through the incision at the bottom of the bag body, compressed air is blown into the bag body of the bagged catalyst by the blowing pipe to accelerate the discharge of the remaining catalyst inside the bag body through the incision of the bag body, which is beneficial to reduce the part of the catalyst remaining in the corner of the bag body, and the waste caused by the catalyst remaining in the bag body; at the same time, after the second sliding drive member drives the corresponding blowing pipe to insert into the bagged catalyst, a number of blowing pipes can be used to assist in limiting and fixing the bagged catalyst, which is beneficial for the grabbing part to grab the bagged catalyst more firmly.

[0018] Preferably, lifting brackets are connected to the two opposite sides of the connecting seat corresponding to the blowing parts, and the lifting brackets are provided with second lifting driving components, which are drivingly connected to the blowing brackets corresponding to the blowing parts for driving the blowing brackets to lift and lower vertically.

[0019] By adopting the above technical scheme, the bagged catalysts in the storage section are usually stacked neatly and tightly. When the manipulator controls the sponge suction cup to adsorb and grab the target bagged catalyst, the blowing parts located on both sides of the sponge suction cup adsorption station are very likely to interfere with the bagged catalysts adjacent to the target bagged catalyst; through the setting of the second lifting drive member, before the manipulator drives the sponge suction cup to grab the target bagged catalyst, the second lifting drive member can first drive the blowing part to move up until the blowing part is higher than the adsorption station of the sponge suction cup, so as to limit the interference between the blowing part and the remaining bagged catalysts when the sponge suction cup grabs the target bagged catalyst on the storage section; after the subsequent manipulator cooperates with the sponge suction cup to grab the bagged catalyst from the material pile, the second lifting drive member drives the blowing part to move down until the blowing part faces the suction cup station of the sponge suction cup, so that the second sliding drive member on the subsequent blowing bracket drives the corresponding blowing pipe to be inserted into the bagged catalyst.

[0020] Preferably, a filter screen is also supported at the top opening of the hopper, and the filter screen is located at the bottom of the bag cutting assembly.

[0021] By adopting the above technical solution, a part of the agglomerated catalyst is filtered out by a filter screen to reduce the agglomerated catalyst from clogging the bottom of the hopper and affecting the subsequent catalyst in the hopper from entering the screw conveyor.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. When adding the catalyst into the reactor, the bagged catalyst in the storage part is grabbed by the grabbing mechanism and moved to the bag cutting assembly above the hopper, and the bag body of the bagged catalyst is cut by the bag cutting assembly to make the catalyst in the bag fall into the hopper. The catalyst falling into the hopper is conveyed to the feed port on the top of the reactor body through the screw conveyor at the bottom of the hopper, so as to realize the automatic addition of the catalyst into the reactor body.

[0023] 2. By supporting the tensioning assembly on the opposite sides of the bag cutting assembly, after the cutter at the bag cutting assembly is subsequently inserted into the bagged catalyst, the tensioning suction cup at the adsorption portion is first driven upward by the first lifting drive component of the tensioning bracket at the tensioning assembly, and the bottom of the bag body of the bagged catalyst is adsorbed and fixed by the tensioning suction cup, and then the first sliding drive component of the tensioning assembly drives the tensioning support to move away from the bag cutting assembly to tension the bottom area of ​​the bag body of the bagged catalyst, so that the cutter at the subsequent bag cutting assembly can more easily cut the bag body of the bagged catalyst.

[0024] 3. By setting the blowing parts on both sides of the sponge suction cup adsorption station, after the manipulator cooperates with the sponge suction cup to grab the bagged catalyst, the second sliding drive part on the blowing part drives the corresponding blowing pipe to be inserted into the bagged catalyst located on the sponge suction cup adsorption station at this time; when the catalyst in the bagged catalyst is subsequently discharged through the incision made by the bag cutting assembly, compressed air is blown into the bag body through the blowing pipe to accelerate the discharge of the catalyst in the bag body through the incision, and at the same time reduce the catalyst residue in the bag body.

Subsequently, the bagged catalyst is moved to the bag cutting assembly 33 by the grabbing mechanism 5, and the bagged catalyst is moved down so that the cutter 332 is inserted into the bottom of the bag body of the bagged catalyst, and then the slide drives the cutter 332 to slide by the rodless cylinder 331, and the cutter 332 is used to cut the bag body to form an incision, so that the catalyst in the bagged catalyst can fall into the hopper 31 through the incision on the bag body.

[0036] Tensioning components 34 are arranged on opposite sides of the rodless cylinder 331. The tensioning part includes a tensioning support 341, a suction part, a first lifting drive and a first sliding drive. The suction part is located above the tensioning support 341. The suction part includes a support plate 342. Two tensioning suction cups 343 are installed on the support plate 342. Both tensioning suction cups 343 are arranged vertically upward. The first lifting drive includes a first lifting cylinder 344. The first lifting cylinder 344 is arranged vertically. The cylinder body of the first lifting cylinder 344 is connected to the tensioning support 341. The top of the piston rod of the first lifting cylinder 344 is connected to the bottom of the support plate 342, so that the first lifting drive is driven and connected to the support plate 342. Subsequently, the first lifting drive can drive the support plate 342 to drive the two tensioning suction cups 343 to rise and fall vertically. The first sliding drive member includes a first sliding cylinder 345, the cylinder body of the first sliding cylinder 345 is horizontally arranged, the cylinder body of the first sliding cylinder 345 is connected to the bag cutting bracket 330, the first sliding cylinder 345 is arranged toward the rodless cylinder 331 and the first sliding cylinder 345 and the rodless cylinder 331 are vertically arranged, the piston rod of the first sliding cylinder 345 is connected to the tensioning support 341, so that the first sliding drive member is driven to be connected to the tensioning support 341, and subsequently the tensioning support 341 can be driven by the first sliding cylinder 345 to move horizontally toward or away from the rodless cylinder 331.

[0037] By setting the tensioning assembly 34 on both sides of the rodless cylinder 331; the subsequent grabbing mechanism 5 moves the bagged catalyst to the bag cutting assembly 33 and after the cutter 332 is inserted into the bottom of the bag body of the bagged catalyst; the first lifting cylinder 344 on the tensioning support 341 drives the suction part to move upward, and the bag body of the bagged catalyst is adsorbed and fixed by the two tensioning suction cups 343 on the suction part; then the first sliding cylinder 345 drives the tensioning support 341 to drive the adsorption part to move away from the rodless cylinder 331, so as to achieve tensioning of the bottom of the bag body of the bagged catalyst, so that when the rodless cylinder 331 drives the cutter 332 to slide, the cutter 332 can more easily cut the bag body of the bagged catalyst. At the same time, after the rodless cylinder 331 cooperates with the cutter 332 to cut an incision at the bottom of the bag, the first sliding cylinder 345 drives the tensioning support 341 to move further away from the rodless cylinder 331, so that the incision at the bottom of the bag is opened at this time, which is conducive to the catalyst in the bag being better discharged through the incision at the bottom of the bag.

[0038] A filter screen 311 is also supported at the bottom opening of the top of the hopper 31.

[0039] Reference Figure 5 and Figure 6 , the grabbing mechanism 5 includes a manipulator 51 and a grabbing part 52. The grabbing part 52 is connected to the driving end of the manipulator 51, and is used to grab the bagged catalyst. In this embodiment, the manipulator 51 adopts a six-axis manipulator 51, so that in actual use, the bagged catalyst can be flexibly moved in cooperation with the grabbing part 52. The grabbing part 52 includes a connecting seat 521 with a connecting flange 520 connected to the top, and the connecting seat 521 can be connected to the driving end of the manipulator 51 through the connecting flange 520; a sponge suction cup 522 is installed at the bottom of the grabbing part 52. When the bagged catalyst on the tray 2 is grabbed by the grabbing mechanism 5, after the manipulator 51 drives the connecting seat 521 to drive the sponge suction cup 522 to move to the target bagged catalyst, the sponge suction cup 522 sucks and fixes the bag body of the target bagged catalyst, and then the bagged catalyst can be grabbed by the grabbing part 52. After the robot 51 cooperates with the sponge suction cup 522 to move the bag of bagged catalyst into the collection box 4 , the sponge suction cup 522 releases the adsorption of the bag, so that the bag of bagged catalyst can fall into the collection box 4 .

[0040] The connection base 521 is provided with two air blowing parts 523; the two air blowing parts 523 are respectively located on opposite sides of the connection base 521, and the two air blowing parts 523 are both arranged toward the adsorption station of the sponge suction cup 522. The air blowing part 523 includes an air blowing bracket 5231, and a plurality of air blowing pipes 5232 are evenly arranged on the side of the air blowing bracket 5231 facing the adsorption station of the sponge suction cup 522, and the end of the air blowing pipe 5232 away from the air blowing bracket 5231 is sharp; the end of the air blowing pipe 5232 close to the air blowing bracket 5231 is connected to an air supply branch pipe, and the air supply branch pipe is connected to an air source. The blowing bracket 5231 is provided with a plurality of second sliding driving members corresponding to the plurality of blowing pipes 5232. The second sliding driving members include a second sliding cylinder 5233. The second sliding cylinder 5233 is arranged toward the adsorption station of the sponge suction cup 522. The cylinder body of the second sliding cylinder 5233 is connected to the blowing bracket 5231, and the piston rod of the second sliding cylinder 5233 is connected to the corresponding blowing pipe 5232. The second sliding driving member is driven and connected to the corresponding blowing pipe 5232, and the blowing pipe 5232 can be subsequently driven by the second sliding cylinder 5233 to move toward or away from the adsorption station of the sponge suction cup 522.

[0041] The connection seat 521 is also provided with two lifting brackets 524 corresponding to the two blowing parts 523. The two lifting brackets 524 are respectively connected to the opposite sides of the connection seat 521, and the two lifting brackets 524 correspond to the two blowing brackets 5231.

The cylinder bodies of the second lifting cylinders 525 are connected to the lifting brackets 524, and the piston rods of the second lifting cylinders 525 are connected to the corresponding blowing brackets 5231. The second lifting drive member is driven to be connected to the corresponding blowing brackets 5231, and the blowing part 523 can be driven to rise and fall vertically through the second lifting cylinders 525 later.

[0042] Reference Figures 3 to 6Through the above arrangement, when the bagged catalyst on the tray 2 is subsequently grabbed by the manipulator 51 in cooperation with the sponge suction cup 522, the corresponding blowing part 523 is first driven upward by the second lifting cylinder 525 on the lifting bracket 524 until the blowing part 523 is higher than the adsorption position of the sponge suction cup 522, so as to limit the interference between the blowing parts 523 located on both sides of the adsorption position of the sponge suction cup 522 and the remaining bagged catalysts adjacent to the target bagged catalyst when the bag body of the target bagged catalyst is subsequently adsorbed and fixed by the sponge suction cup 522. After the manipulator 51 cooperates with the sponge suction cup 522 to grab the target bagged catalyst from the tray 2, the second lifting cylinder 525 on the lifting bracket 524 drives the blowing part 523 to move downward until the blowing part 523 moves toward the target bagged catalyst adsorbed by the sponge suction cup 522; then the second sliding cylinder 5233 on the blowing bracket 5231 drives the blowing pipe 5232 to move toward the bagged catalyst adsorbed by the sponge suction cup 522 until the blowing pipe 5232 is inserted into the bagged catalyst. When the subsequent bag cutting component 33 cuts an incision at the bottom of the bag body to allow the catalyst to flow out through the incision, compressed air is blown into the bag body through the blowing pipe 5232, which is conducive to accelerating the discharge of the remaining catalyst in the bag body from the incision at the bottom of the bag body on the one hand, and effectively reduces the catalyst residue in the corners of the bag body on the other hand.

[0043] At the same time, after the second sliding cylinder 5233 is used to drive the corresponding blowing pipe 5232 to be inserted into the bagged catalyst, the inserted blowing pipes 5232 can be used to assist in limiting and fixing the bagged catalyst, which is beneficial to limit the bagged catalyst from detaching from the sponge suction cup 522, thereby facilitating the grasping portion 52 to grasp the bagged catalyst more firmly.

[0044] The implementation principle of the embodiment of the present application is: Preparation for grabbing the bagged catalyst: The corresponding blowing part 523 is driven upward by the second lifting cylinders 525 on the lifting brackets 524 on both sides of the connecting seat 521 until the blowing part 523 is higher than the adsorption position of the sponge suction cup 522.

[0045] Grabbing and transferring bagged catalyst: After the bagged catalyst on the tray 2 is grabbed by the manipulator 51 in cooperation with the sponge suction cup 522, the corresponding blowing part 523 is driven downward by the second lifting cylinder 525 on the lifting bracket 524 on both sides of the connecting seat 521 until the blowing part 523 is directed toward the adsorption position of the sponge suction cup 522; then the corresponding blowing pipe 5232 is driven to move toward the adsorption position close to the sponge suction cup 522 by the second sliding cylinder 5233 on the blowing bracket 5231 of the blowing part 523 until it is inserted into the bagged catalyst adsorbed by the sponge suction cup 522; the bagged catalyst is transferred to the cutter 332 of the bag cutting assembly 33 by the manipulator 51 in cooperation with the sponge suction cup 522, and the bagged catalyst continues to be moved downward until the cutter 332 is inserted into the bag body of the bagged catalyst.

[0046] Tensioning treatment of the bagged catalyst: the first lifting cylinder 344 on the tensioning support 341 drives the adsorption part to move upward, and the tensioning suction cup 343 at the adsorption part adsorbs and fixes the bottom of the bag; the first sliding cylinder 345 drives the tensioning support 341 to drive the adsorption part to slide in the direction away from the rodless cylinder 331 to tension the bottom area of ​​the bag.

[0047] Cutting of bagged catalyst: The rodless cylinder 331 drives the cutter 332 to slide to make an incision at the bottom of the bag, so that the catalyst in the bag falls into the hopper 31 through the incision. During this period, the first sliding cylinder 345 further drives the tensioning support 341 to drive the adsorption part to slide away from the rodless cylinder 331 to open the incision of the bag; at the same time, compressed air is blown into the bag through the blowing pipe 5232 of the blowing part 523.

[0048] Directed delivery of catalyst: The catalyst dropped into the hopper 31 is delivered to the feed port at the top of the reactor body 1 via the screw conveyor 32 at the bottom of the hopper 31 , thereby completing the automatic addition of the catalyst inside the reactor body 1 .

[0049] Bag transfer: After all the catalyst in the bag flows out through the incision, the tensioning suction cup 343 releases the adsorption of the bag; the corresponding blowing tube 5232 is driven out of the bag by the second sliding cylinder 5233 on the blowing bracket 5231, and the bag is moved into the collection box 4 by the manipulator 51 in cooperation with the sponge suction cup 522, and the sponge suction cup 522 releases the adsorption of the bag, so that the bag falls into the collection box 4.

[0050] The present application can realize automatic addition of catalyst to the reactor body 1 , and the operation process does not require manual intervention, which effectively improves the overall operation efficiency and reduces the difficulty of adding catalyst to the reactor body 1 .

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
