Description

Technical Field

[0001] The utility model relates to the technical field of reaction kettles, in particular to a reaction kettle with a weighing function. Background Art

[0002] Reactors are essential key equipment in chemical production. Existing reactors lack the function of accurately weighing materials, which means that when adding materials to the reactor, workers need to move the materials to an external workbench for weighing and then manually transfer them to the reactor again. This is inconvenient to operate, and there is a risk of material loss or contamination after weighing, which reduces work efficiency.

[0003] For example, a reactor disclosed in the patent with publication number CN219400182U, although the reactor can not only stir the chemical raw materials that need to be mixed by rotating the inner chamber during the chemical reaction in the reactor, so that the chemical reaction can be carried out more fully, but also after the production of the raw materials is completed, the rotation of the rotating drum driven by the rotating motor and the cooperation of the cleaning mechanism make the cleaning of the inner wall of the reactor simpler and faster, and effectively prevent the inner wall of the reactor from being corroded by chemical residues while controlling the cleaning cost and improving the practicality of the product. However, when the reactor is actually used, when multiple raw materials need to be added to the reactor for reaction, the staff is required to weigh the multiple raw materials on the workbench, and then transfer the weighed multiple raw materials from the workbench to the reactor for reaction, which makes it inconvenient for the staff in actual operation and affects the staff's work efficiency.

[0033] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are only used to explain the utility model but not to limit it.

[0034] The following is combined with Figure 1-Figure 7 This embodiment is described in further detail.

[0035] like Figure 1 As shown, a reactor with a weighing function in this embodiment includes a base 100 and a reactor body 110, wherein a cavity 201 with an opening upward is provided in the reactor body 110, a stirring assembly is provided in the cavity 201, a cover plate 120 for closing the cavity 201 is provided on the upper end surface of the reactor body 110, a mounting groove 401 is provided on the upper end surface of the cover plate 120 along its radial direction, a connecting groove 402 for connecting the cavity 201 is provided on the bottom wall of the mounting groove 401, a lap groove 403 is provided on the mounting groove 401 and at one end, an electronic scale 410 for weighing materials is installed in the lap groove 403, plates 130 are provided on both sides of the mounting groove 401, and a There is a slidable push plate 140 located above the electronic scale 410. The push plate 140 is used to push the material on the electronic scale 410 to the connecting groove 402. There is also a slidable opening and closing plate 300 located below the electronic scale 410 in the mounting groove 401. The opening and closing plate 300 is provided with a through groove 301 corresponding to the connecting groove 402. The opening and closing plate 300 is away from the electronic scale 410 to achieve the closure of the connecting groove 402. A moving component for driving the opening and closing plate 300 to move is provided in the plate body 130. When the push plate 140 is used to push the material on the electronic scale 410 to the connecting groove 402, the moving component drives the opening and closing plate 300 to approach the electronic scale 410 to achieve the opening of the connecting groove 402.

[0036] In this embodiment, the cover plate 120 is installed on the upper end surface of the kettle body 110 to close the upper end opening of the cavity 201. When the kettle body 110 is required to react with multiple materials, the materials are placed on the electronic scale 410 on the cover plate 120 in sequence for weighing, so as to weigh out the appropriate amount of materials. After the weighing of the materials is completed, the materials accumulated on the electronic scale 410 are pushed to the connecting groove 402 by the pushing plate 140. In this process, the moving component drives the opening and closing plate 300 to slide in the installation groove 401, so that the opening and closing plate 300 slides to the bottom of the electronic scale 410, thereby making the through groove 302 on it open. 01 can correspond to the connecting groove 402, that is, the connecting groove 402 is opened, so that the push plate 140 can push the material weighed on the electronic scale 410 into the connecting groove 402, and enter the cavity 201 for reaction. Compared with the existing ones, this kind of reactor with weighing function can push the material weighed on the electronic scale 410 into the cavity 201 for reaction through the push plate 140 during actual use, which is simple to operate and avoids the staff from weighing the material on the workbench and then manually transferring the weighed material to the reactor body 110 for reaction. It is more convenient in actual use and improves work efficiency.

[0037] Among them, the electronic scale 410 is a prior art, so it is not described in detail;

[0038] In actual use, the push plate 140 is U-shaped, and is slidably disposed between the plate bodies 130 above the electronic scale 410. Its size can be adapted to the electronic scale 410, so that it can scrape the material on the electronic scale 410 to the connecting groove 402 when it is scraped on the electronic scale 410, wherein one side of the connecting groove 402 is flush with the discharge end of the electronic scale 410, so as to ensure that the push plate 140 pushes the material to the connecting groove 402;

[0039] The scraper 411 is fixedly mounted on the lower end surface of the electronic scale 410 and is flush with one side of the connecting groove 402. The lower end of the scraper 411 is slidably arranged on the upper side of the opening and closing plate 300. Therefore, when the material is pushed onto the opening and closing plate 300 by the pushing plate 140, when the opening and closing plate 300 moves to the bottom of the electronic scale 410 under the action of the moving assembly, the scraper 411 can scrape the material to prevent it from moving with the opening and closing plate 300 to the bottom of the electronic scale 410, resulting in the material being unable to be completely added to the cavity 201. The structure in this embodiment enables the pushing plate 140 to completely push the material on the electronic scale 410 to the connecting groove 402, and the opening and closing plate 300 just moves to the bottom of the electronic scale 410, so that the through groove 301 is opposite to the connecting groove 402. Under the action of the scraper 411, the material is completely added to the cavity 201 from the connecting groove 402.

[0040] The lower side of the opening and closing plate 300 is slidably fitted with the bottom wall of the installation groove 401. When the material reacts in the cavity 201, the push plate 140 is driven to reset, driving the moving assembly to drive the opening and closing plate 300 to slide out of the installation groove 401 located below the electronic scale 410, so that the through groove 301 and the connecting groove 402 on the opening and closing plate 300 are staggered, so that the opening and closing plate 300 closes the connecting groove 402, thereby preventing the dust outside the kettle body 110 from entering the cavity 201 through the connecting groove 402 when multiple materials react in the cavity 201, and affecting the materials reacting in the cavity 201.

[0041] The upper end surface of the base 100 is provided with a bottom groove, and the kettle body 110 is installed on the base 100 through the bottom groove. The stirring assembly includes a rotatable rotating rod 210, and a plurality of stirring rods 211 are arranged on the side wall of the rotating rod 210. One end of the rotating rod 210 is installed on the bottom wall of the cavity 201 through a bearing, so that the rotating rod 210 can be rotatably installed in the cavity 201. The legs 101 for supporting the base 100 are fixedly installed on the lower end surface of the base 100 and at the corners, so that there is a certain gap between the base 100 and the ground. A motor 220 is installed on the lower end surface of the base 100, and the output shaft of the motor 220 passes through the base 100 and is connected to the rotating rod 210, so that the rotating rod 210 can be driven to rotate by the motor 220, so that the rotating rod 210 drives the stirring rod 211 to rotate in the cavity 201, and the materials in the cavity 201 are mixed and stirred, so that the materials in the cavity 201 can react better.

[0042] A circular hole is provided on the lower end surface of the cover plate 120 for inserting the upper end of the rotating rod 210, so that both ends of the rotating rod 210 are evenly installed in the cavity 201, thereby preventing the upper end of the rotating rod 210 from swinging when the rotating rod 210 rotates, thereby affecting the mixing effect of the stirring rod 211 on the material;

[0043] The plate body 130 is fixedly mounted on the cover plate 120 and is located on both sides of the mounting groove 401. The lower end surface of the plate body 130 can limit the two ends of the electronic scale 410 in the overlapping groove 403, thereby realizing the installation of the electronic scale 410 in the overlapping groove 403.

[0044] In actual use, a handle 142 for driving the push plate 140 to move is fixedly installed on one side wall of the push plate 140. The staff can better drive the push plate 140 to move through the handle 142, and push the material weighed on the electronic scale 410 into the cavity 201 for reaction.

[0045] like Figure 1-7As shown, in this embodiment, a cavity 701 is provided in the plate body 130, and a first slide groove 601 communicating with the cavity 701 is provided on the side wall of the plate body 130 facing the installation groove 401 along its length direction, and a vertical plate 310 is provided on the upper end surface of the opening and closing plate 300, and a fixing block 610 extending into the corresponding first slide groove 601 is provided on the side wall opposite to the vertical plate 310, and a first rack 700 is provided on the fixing block 610;

[0046] The moving component includes a rotatable gear 710 disposed in the cavity 701. The gear 710 is meshed with the first rack 700. The gear 710 drives the first rack 700 on the opening and closing plate 300 to slide along the first slide groove 601, so that the through groove 301 on the opening and closing plate 300 is connected with the connecting groove 402. A driving member for driving the gear 710 to rotate is provided on the pushing plate 140.

[0047] In this embodiment, through the arrangement of the cavity 701, the first slide groove 601, the vertical plate 310, the fixed block 610, the first rack 700, the gear 710 and the driving member, the vertical plate 310 is fixedly installed on the opening and closing plate 300, the fixed block 610 is fixedly installed on the vertical plate 310, and one end of the fixed block 610 extends into the cavity 701 through the first slide groove 601, and then the first rack 700 is fixedly installed on the fixed block 610 located in the cavity 701 along the moving direction of the opening and closing plate 300. When the gear 710 rotates, it can drive the first rack 700 to move in the cavity 701, and drive the fixed block 610 on the vertical plate 310 to move along the first slide groove 601, so as to realize the movement of the opening and closing plate 300 in the installation groove 401;

[0048] There are holes on the opposite side walls of the cavity 701, and a plug rod 711 inserted into the corresponding plug hole is fixedly installed on the opposite side wall of the gear 710. By inserting the plug rod 711 on the gear 710 into the corresponding plug hole, the gear 710 is rotatably installed in the cavity 701;

[0049] The driving member on the push plate 140 can drive the gear 710 in the cavity 701 to rotate, that is, drive the opening and closing plate 300 to move in the installation groove 401;

[0050] The vertical plate 310 is located on the opening and closing plate 300 and is flush with the side wall of the through slot 301 away from the push plate 140. The vertical plate 310 intercepts part of the material, thereby preventing part of the material from overflowing from the vertical plate 310 into the installation slot 401, resulting in the weighed material being unable to be completely added to the cavity 201.

[0051] In actual use, guide slopes 501 are provided on the side walls of the through groove 301 facing the plate body 130. When part of the material is located on the opening and closing plate 300 and on both sides of the through groove 301, this part of the material will slide along the guide slopes 501 and enter the through groove 301, and then react in the cavity 201, thereby avoiding part of the material from accumulating on the opening and closing plate 300, causing all the materials weighed on the electronic scale 410 to enter the cavity 201 for reaction, affecting actual use.

[0052] like Figure 1-7 As shown, in this embodiment, the side wall of the plate body 130 facing the installation groove 401 is provided with a second slide groove 602 connected to the cavity 701 along its length direction, and the opposite side wall of the push plate 140 is provided with a baffle portion 141;

[0053] The driving member includes a protrusion 620 disposed on one side of the baffle portion 141 and extending into the cavity 701. The protrusion 620 located in the cavity 701 is provided with a second rack 720 meshing with the gear 710. The movement of the push plate 140 drives the second rack 720 to move, thereby realizing the rotation of the gear 710.

[0054] In this embodiment, by setting the second slide groove 602, the baffle portion 141, the protrusion 620 and the second rack 720, the baffle portion 141 is fixedly installed on both sides of the push plate 140, and the baffle portion 141 is fixedly installed with protrusions 620, and the protrusions 620 extend into the cavity 701 through the second slide groove 602. The second rack 720 is fixedly installed on the protrusion 620 located in the cavity 701 along the moving direction of the push plate 140, and the protrusion 620 is driven to slide along the second slide groove 602 by the movement of the push plate 140, so that the second rack 720 in the cavity 701 drives the gear 710 to rotate, that is, the opening and closing plate 300 moves, so that the through groove 301 on the opening and closing plate 300 corresponds to or is misaligned with the connecting groove 402;

[0055] The baffle portion 141 blocks the second chute 602, thereby preventing the material on the electronic scale 410 from entering the cavity 701 through the second chute 602 when the push plate 140 pushes the material on the electronic scale 410 to move, resulting in the material weighed on the electronic scale 410 not being able to enter the cavity 201 for reaction, thereby affecting actual use;

[0056] The two ends of the push plate 140 extend into the corresponding second slide grooves 602 through the protrusions 620, so as to realize the sliding installation of the push plate 140 between the two plate bodies 130;

[0057] A card slot 511 is provided on the side wall of the baffle portion 141 facing the vertical plate 310 along its length direction, and a card plate 520 is provided on the side wall of the vertical plate 310, one end of which is inserted into the corresponding card slot 511. The card plate 520 blocks the first chute 601, thereby preventing the material on the opening and closing plate 300 from entering the cavity 701 through the first chute 601 when the material on the opening and closing plate 300 is moved, resulting in the material weighed on the electronic scale 410 not being able to enter the cavity 201 for reaction, thereby affecting actual use;

[0058] The clamping plate 520 is inserted into the clamping slot 511 for limiting, so that the vertical plate 310 is more stable when moving, that is, the opening and closing plate 300 has a better moving effect in the installation slot 401;

[0059] In actual use, the cover plate 120 is installed on the kettle body 110 through threads, so that the cover plate 120 can be disassembled on the kettle body 110. When the material in the cavity 701 completes the reaction, the cover plate 120 can be removed from the kettle body 110 by rotating the cover plate 120, so as to take out the reacted material.

[0060] Working principle: First, the material to be reacted is placed on the electronic scale 410 for weighing. When the weighing of the material is completed, the push plate 140 is driven to move by the handle 142, so that the push plate 140 pushes the material on the electronic scale 410 to the connecting groove 402. When the push plate 140 moves, the second rack 720 on the push plate 140 drives the gear 710 to rotate, and the first rack 700 is driven to move by the rotation of the gear 710, so that the opening and closing plate 300 moves toward the installation groove 401 under the electronic scale 410, so that the through groove 301 on the opening and closing plate 300 is connected with the connecting groove 402, so that the push plate 140 can push the material from the through groove 301 to the connecting groove 402. The connecting groove 402 reacts when entering the cavity 201. When part of the material is accumulated on the opening and closing plate 300, when the opening and closing plate 300 is moving, the scraper 411 on the electronic scale 410 will scrape the material accumulated on the opening and closing plate 300 into the cavity 201. When multiple materials enter the cavity 201, the motor 220 drives the rotating rod 210 to rotate, so that the stirring rod 211 on the rotating rod 210 mixes and stirs the materials in the cavity 201, so that the materials in the cavity 201 can react with replacement. When multiple materials have completed the reaction in the cavity 201, the cover plate 120 can be removed by rotating the cover plate 120 to take out the materials in the cavity 201 that have completed the reaction.

[0061] In short, the above is only a preferred embodiment of the present utility model, and all equivalent changes and modifications made according to the scope of the patent application of the present utility model should fall within the scope of the present utility model patent.
