Description

TECHNICAL FIELD

[0001] The present application relates to the field of chemical equipment, in particular to a reaction kettle with automatic catalyst adding function. BACKGROUND

[0002] In the process of stirring materials, the reaction kettle needs to add catalyst into the kettle body at a certain time period to improve the chemical reaction efficiency of the materials inside the kettle body.

[0003] At present, the addition operation of the catalyst of the reaction kettle is mostly completed by manual operation. Specifically, the operator carries the bagged catalyst to the top of the reaction kettle, then unpacks the bagged catalyst, and pours the bagged catalyst into the kettle body to complete the addition operation of the catalyst.

[0004] For the above related technology, the above-mentioned catalyst addition operation process usually needs to be completed by multiple operators, and the overall operation efficiency is low. Moreover, since the feeding port of the reaction kettle is located at a high position of the kettle body, the operator usually needs to climb to the feeding port of the kettle body by means of a ladder or the like to complete the pouring of the catalyst, which is inconvenient to operate. Therefore, there is room for improvement. SUMMARY

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

[0006] The reaction kettle with automatic catalyst adding function provided by the present application adopts the following technical scheme:

[0007] A reaction kettle with automatic catalyst adding function, comprising a reaction kettle body, a storage part, a conveying mechanism, a collecting part and a grabbing mechanism;

[0008] The storage part is used for stacking bagged catalysts;

[0009] The conveying mechanism comprises a hopper, the bottom of the hopper is communicated with a screw conveyor, the output end of the screw conveyor extends above the feeding port of the reaction kettle body; a bag cutting assembly for cutting the bag of the bagged catalyst is further arranged on the top of the hopper;

[0010] The collecting part is used for storing the bag of the bagged catalyst;

[0011] The grabbing mechanism is used for grabbing and moving the bagged catalyst at the storage part to the bag cutting assembly of the hopper, and is also used for moving the bag of the bagged catalyst from the bag cutting assembly to the collecting part.

[0012] By adopting the above technical scheme, the bagged catalyst located at the storage part is grabbed and moved to the bag cutting assembly above the hopper by the grabbing mechanism, and the bag cutting assembly cuts the bottom of the bag of the bagged catalyst to form a cut, so that the catalyst in the bagged catalyst falls into the hopper through the cut. The catalyst falling into the hopper is upwardly conveyed by the screw conveyor at the bottom of the hopper and discharged into the feed hopper of the reaction kettle body through the output end of the screw conveyor, realizing automatic feeding of the catalyst of the reaction kettle body. The remaining bag is transferred by the grabbing mechanism and placed into the collection box. Compared with the traditional manual catalyst feeding operation mode, the overall operation efficiency is effectively improved, and manual intervention is not required throughout the process, so that the catalyst feeding of the reaction kettle is more simple and convenient.

[0013] Preferably, the bag cutting assembly comprises a rodless cylinder and a cutter, the cutter being connected to the sliding table of the rodless cylinder, and the cutter being vertically upwardly arranged.

[0014] By adopting the above technical scheme, after the grabbing mechanism moves the bagged addition above the cutter, the bagged catalyst continues to move downward until the cutter is inserted into the bottom of the bag of the bagged catalyst. By driving the cutter to slide along the horizontal direction by the rodless cylinder, a cut for the outflow of the catalyst can be formed in the bottom of the bag of the bagged catalyst by the cutter.

[0015] Preferably, the rodless cylinder is provided with a tensioning assembly on opposite sides, the tensioning assembly comprising a tensioning support, an adsorption part, a first lifting driving member and a first sliding driving member, the adsorption part being located above the tensioning support; the adsorption part comprises a support plate, a plurality of tensioning suction cups being vertically upwardly mounted on the support plate; the first lifting driving member is installed on the tensioning support and drivingly connected with the support plate, for driving the support plate to vertically lift; the first sliding driving member is drivingly connected with the tensioning support, for driving the tensioning support to move along the horizontal direction towards or away from the rodless cylinder.

[0016] By adopting the above technical solution, the tensioning component is set up, and after the subsequent grabbing mechanism grabs 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.

[0017] Preferably, the grabbing mechanism includes a manipulator and a grabbing portion, and the grabbing portion is used to grab the bagged catalyst.

[0018] 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.

[0019] 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.

[0020] By adopting the above technical solution, the manipulator drives the connecting seat to move the sponge suction cup to the top of 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 the top of 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.

[0021] 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 the side of the sponge suction cup adsorption station upward, and the blowing bracket is provided with a plurality of second sliding driving members corresponding to the plurality of blowing pipes, and the second sliding driving members are drivingly connected to the corresponding blowing pipes for driving the corresponding blowing pipes to move horizontally toward or away from the sponge suction cup adsorption station.

[0022] By adopting the above technical scheme, after the mechanical hand cooperates with the sponge suction cup to grab the bagged catalyst, the second sliding driving element on the blowing support drives the corresponding air outlet pipe to move close to the sponge suction cup adsorption station, until the blowing pipe is inserted into the bagged catalyst adsorbed by the sponge suction cup at this time; while the catalyst inside the subsequent bagged catalyst falls out through the bag body bottom cutout, compressed air is blown into the bag body inside the bagged catalyst at this time by the blowing pipe, so as to accelerate the remaining catalyst inside the bag body to be discharged through the bag body cutout, and at the same time, it is beneficial to reduce the residual catalyst in the corner of the bag body and reduce the waste caused by the residual catalyst inside the bag body; at the same time, after the second sliding driving element drives the corresponding blowing pipe to be inserted into the bagged catalyst, a plurality of blowing pipes can be used to assist in limiting and fixing the bagged catalyst, which is beneficial to the more stable grabbing of the bagged catalyst by the grabbing part.

[0023] Preferably, the connecting seat is connected with a lifting support on the two opposite sides corresponding to the blowing part, the lifting support is provided with a second lifting driving element, and the second lifting driving element is drivingly connected with the blowing support corresponding to the blowing part, for driving the blowing support to vertically ascend and descend.

[0024] By adopting the above technical scheme, the bagged catalysts in the storage part are usually neatly and closely stacked, and when the sponge suction cup is controlled by the mechanical hand to adsorb and grab the target bagged catalyst, the blowing part located on both sides of the sponge suction cup adsorption station is easy to interfere with the bagged catalysts adjacent to the target bagged catalyst; by the setting of the second lifting driving element, before the mechanical hand drives the sponge suction cup to grab the target bagged catalyst, the second lifting driving element can first drive the blowing part to move upward, 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 part; after the subsequent mechanical hand cooperates with the sponge suction cup to grab the bagged catalyst from the material pile, the second lifting driving element drives the blowing part to move downward again, until the blowing part is directed to the suction cup station of the sponge suction cup, so that the second sliding driving element on the blowing support drives the corresponding blowing pipe to be inserted into the bagged catalyst.

[0025] Preferably, a filter screen is further arranged at the top opening of the hopper, and the filter screen is located at the bottom of the bag cutting assembly.

[0026] By adopting the above technical scheme, part of the agglomerated catalyst is filtered out by the filter screen, so as to reduce the agglomerated catalyst accumulated and blocked at the bottom of the hopper, and affect the subsequent catalyst in the hopper into the screw conveyor.

[0027] In summary, the present application has at least one of the following beneficial technical effects:

[0028] 1. When the catalyst is put into the reaction kettle, the bagged catalyst in the storage part is grabbed and moved to the bag cutting assembly above the hopper through the grabbing mechanism, the bag body of the bagged catalyst is cut through the bag cutting assembly, so that the catalyst in the bag body falls into the hopper, and the catalyst falling into the hopper is directionally conveyed to the feed port at the top of the reaction kettle body through the screw conveyor at the bottom of the hopper, realizing automatic feeding of the catalyst into the reaction kettle body.

[0029] 2. By providing a tensioning assembly on the opposite sides of the bag cutting assembly, after the cutter at the bag cutting assembly is inserted into the bagged catalyst, the first lifting drive of the tensioning support at the tensioning assembly is first driven to move the tensioning suction disc at the suction part upward, and the bottom of the bag body of the bagged catalyst is adsorbed and fixed through the tensioning suction disc, and then the first sliding drive of the tensioning assembly drives the tensioning support to move away from the bag cutting assembly, so as to tension the bottom area of the bag body of the bagged catalyst, so that the cutter at the bag cutting assembly is more easily to cut open the bag body of the bagged catalyst.

[0030] 3. By providing the air blowing part on both sides of the sponge suction station, after the bagged catalyst is grabbed by the mechanical hand cooperating with the sponge suction disc, the corresponding air blowing pipe is inserted into the bagged catalyst located on the sponge suction station at this time through the second sliding drive of the air blowing part; when the catalyst in the bagged catalyst is discharged through the cutout cut by the bag cutting assembly, compressed air is blown into the bag body through the air blowing pipe, so as to accelerate the catalyst in the bag body to be discharged through the cutout, and meanwhile, the catalyst residue in the bag body can be reduced.
