Description

Technical Field

[0001] This utility model belongs to the field of reaction vessel technology, and in particular relates to a continuous feeding mechanism for a sodium metabisulfite reaction vessel. Background Technology

[0002] A reaction vessel is a container that allows for physical or chemical reactions. In the preparation of sodium metabisulfite, it needs to be added to a reaction vessel for thorough mixing. During the preparation of sodium metabisulfite, soda ash and water are stirred evenly at a certain molar ratio. When Na2Co3nH2O is formed in lumps, it is placed into the reaction vessel, with a certain gap between the lumps. Then SO2 is introduced, and the added sodium metabisulfite and SO2 are stirred and mixed evenly by the stirring blades in the reaction vessel until the reaction is complete. The lumps are then removed and crushed into the finished product.

[0003] Chinese utility model patent CN219072896U discloses a reactor feeding mechanism, comprising a reactor, a lid rotatably connected to the top of the reactor, a fixed plate fixedly connected to the outer side of the upper end of the reactor, a lifting device at the right end of the reactor, and a loading box at the lower left corner of the lifting device. In this utility model, through the lifting device and loading box, the device can drive a lead screw to rotate via a servo motor. The rotation of the lead screw drives the lead screw sleeve to rotate, which in turn drives the loading box to move synchronously. The loading box rises or falls stably under the limit of the upright, pouring raw materials from the upper right side of the loading box into it. When the loading box rises above the reactor, an electric telescopic rod is activated to drive a slider to slide, which in turn drives a connecting rod to move. The connecting rod then drives a sealing plate to rotate, opening the left end of the box, facilitating the rapid entry of large quantities of raw materials into the reactor.

[0004] However, the above-mentioned device has the following technical problems in actual use:

[0005] 1. The above-mentioned device loads materials into a loading box and uses the lifting and lowering of the loading box to lift the materials so that they can be put into the reactor through the feed inlet. However, the above-mentioned device requires control of the lifting and lowering of the loading box. When the loading box loaded with too much material is moved to a high place, there is a risk that it may fall or drop, which poses a safety hazard.

[0006] Second, in addition, due to the limited internal space of the loading box in the above-mentioned device, it cannot load too much material, which requires frequent lifting and lowering to realize the transportation of materials. However, during the up-and-down movement of the loading box, it is necessary to wait and cannot perform feeding operations, thus failing to guarantee the continuous delivery of materials. Utility Model Content

[0007] This utility model provides a continuous feeding mechanism for a sodium metabisulfite reactor, which aims to solve the problem mentioned in the background art that when the material-filled container is moved to a high position, there is a risk of it falling or dropping, posing a significant safety hazard. In addition, due to the limited internal space of the material-filled container, the device needs to be frequently raised and lowered to transport the material. During the raising and lowering process, feeding operations cannot be performed, thus affecting the continuous feeding of the material.

[0008] This utility model is implemented as follows: a continuous feeding mechanism for a sodium metabisulfite reactor includes: a reactor body with a feed inlet on its top wall; an annular baffle fixedly installed on the top wall of the reactor body, the annular baffle surrounding the outside of the feed inlet; a lifting mechanism disposed on one side of the reactor body, with its top end connected to the inside of the annular baffle, used to lift and transport material into the annular baffle and feed it into the reactor body through the feed inlet; and a quantitative dispensing component disposed inside the annular baffle, having: a rotating component rotatably connected to the annular baffle, the bottom end of the rotating component being fixedly connected to multiple scraper plates. The bottom wall of the device slides against the top wall of the reactor body, and a storage area is formed between each pair of adjacent scraper plates. The rotating assembly is used to rotate the materials stored in the multiple storage areas sequentially toward the feed inlet. In this scheme, the device has a lifting seat on one side of the reactor body. The rotating motor controls the rotation of the screw conveyor. The screw conveyor lifts the material input from the feeding box sequentially and orderly, and then discharges it into the annular enclosure through the discharge pipe, and then enters the reactor body through the feed inlet. In this way, the material is always inside the lifting seat during the lifting process, and the screw conveyor will not cause the material to fall when conveying the material, thereby avoiding the situation where the falling material may endanger the staff.

[0009] It should be noted that, as long as the operator continuously feeds materials into the feeding box, the rotating screw conveyor will continuously transport the materials into the circular enclosure, thereby reducing downtime during the feeding process and effectively improving feeding efficiency.

[0010] In addition, the rotating seat in this device can be controlled by a drive motor to rotate. The rotating seat drives multiple scraper plates to rotate inside the annular enclosure. In actual operation, the rotating seat drives each storage area to rotate sequentially to the bottom of the corresponding discharge pipe. After a certain amount of material discharged through the discharge pipe is stored in the storage area, the rotating seat rotates to rotate the next storage area to the bottom of the discharge pipe and rotates the storage area loaded with material to the inlet position. The material in the storage area is discharged into the reactor body through the inlet, realizing quantitative and continuous feeding of materials.

[0011] Preferably, the lifting mechanism includes: a lifting seat erected on one side of the reactor body, a lifting cavity opened in the lifting seat, a spiral conveying rod rotatably connected in the lifting cavity, and a rotating motor fixedly connected to the top wall of the lifting seat, the output end of which is fixedly connected to the end of the spiral conveying rod; a feeding box fixedly installed on the bottom side wall of the lifting seat, the feeding box having a feeding cavity communicating with the lifting cavity; and a discharge pipe provided on the top side wall of the lifting seat, the discharge pipe having a discharge cavity communicating with the lifting cavity, and one end of the discharge pipe penetrating to the inside of the annular enclosure; in this scheme, the material is manually fed into the feeding box, the material enters the lifting cavity through the feeding cavity opened in the feeding box, and then the output end of the rotating motor controls the spiral conveying rod to rotate, the spiral conveying rod conveys the material entering the lifting cavity sequentially and orderly to a higher position, and then discharges it into the annular enclosure through the discharge cavity in the discharge pipe, and enters the designated storage area.

[0012] Preferably, the inner bottom wall of the feeding chamber is provided with a first slope that is inclined toward the lifting chamber, and the inner bottom wall of the discharging chamber is provided with a second slope that is inclined toward the inner side of the annular enclosure. In this scheme, the purpose of providing the first slope is to facilitate the rapid transport of materials entering the feeding chamber to the lifting chamber, thereby preventing materials from accumulating and blocking the feeding chamber. At the same time, the purpose of providing the second slope is to facilitate the rapid flow of materials from the discharging chamber into the annular enclosure, thereby preventing materials from accumulating and blocking the discharging chamber.

[0013] Preferably, the rotating assembly includes: two support seats symmetrically fixed to the top wall of the annular enclosure, a connecting plate horizontally fixed between the top ends of the two support seats, a drive motor fixed to the top wall of the connecting plate, a rotating seat fixed to the output end of the drive motor, and the bottom wall of the rotating seat slidingly against the top wall of the reactor body. Multiple scraping plates are fixed to the outer peripheral wall of the rotating seat. In this configuration, when the output end of the drive motor rotates, it drives the rotating seat fixed to it to rotate, which in turn drives the multiple scraping plates on its outer wall to rotate around it. Since a storage area is formed between each pair of adjacent scraping plates, when the rotating seat rotates, the storage area will be rotated sequentially to below the corresponding discharge pipe, facilitating the collection of material discharged from the discharge pipe. Simultaneously, the scraping plates can scrape the material in the storage area into the inlet, thereby realizing the feeding of material.

[0014] Preferably, multiple scraper blades are fixed to the outer peripheral wall of the rotating seat at equal angles, and the end of each scraper blade away from the rotating seat is slidably attached to the inner peripheral wall of the annular enclosure. In this scheme, the equal angle of multiple scraper blades can ensure the accuracy of material delivery each time, and the sliding attachment of one end of the scraper blade to the inner peripheral wall of the annular enclosure can prevent the material from falling off when the storage area rotates.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This utility model provides a continuous feeding mechanism for a sodium metabisulfite reactor.

[0016] 1. In this device, a lifting seat is set on one side of the reactor body. The rotating motor controls the rotation of the screw conveyor. The screw conveyor lifts the material input from the feeding box in an orderly manner, and then discharges it into the annular enclosure through the discharge pipe, and then enters the reactor body through the feed port. In this way, the material is always inside the lifting seat during the lifting process, and the screw conveyor will not cause the material to fall when conveying the material, thereby avoiding the situation where the falling material may endanger the staff.

[0017] 2. In this device, the rotating seat can be controlled by a drive motor to rotate. The rotating seat drives multiple scraper plates to rotate inside the annular enclosure. In actual operation, the rotating seat drives each storage area to rotate sequentially to the bottom of the corresponding discharge pipe. After a certain amount of material discharged through the discharge pipe is stored in the storage area, the rotating seat rotates to rotate the next storage area to the bottom of the discharge pipe and rotates the storage area loaded with material to the inlet position. The material in the storage area is discharged into the reactor body through the inlet, realizing quantitative and continuous feeding of materials. Attached Figure Description
