Description

Technical Field

[0001] This utility model relates to the field of papermaking equipment technology, and more specifically, to an online bleaching agent addition device that can accurately measure bleaching agents. Background Technology

[0002] The papermaking process mainly includes raw material preparation, cooking, washing, screening, bleaching, and papermaking. First, raw materials such as wood are made into fragments, and the fibers are separated by cooking to form pulp. Then, washing and screening are carried out to remove impurities. The bleaching process is a key step that requires the use of bleaching agents. Here, bleaching agents such as chlorine, chlorine dioxide, or hydrogen peroxide are used to chemically react with the lignin in the pulp, effectively removing its coloring structure, thereby significantly improving the whiteness and purity of the pulp to meet the quality requirements of different papers. Finally, the purified and prepared pulp is processed through papermaking, pressing, and drying to produce finished paper. In the bleaching process, an additive device is needed when adding bleaching agents to the bleaching tank.

[0003] Existing addition devices use a metering pump to measure the volume of bleaching agent and add it to the bleaching tank. However, the bleaching agent is usually added to the bleaching tank at a single point, resulting in excessive concentration of the bleaching agent. The bleaching agent requires a long stirring time to be fully dispersed, which reduces the bleaching efficiency. In view of this, this utility model proposes an online addition device for bleaching agent that can accurately measure the volume. Utility Model Content

[0004] This invention addresses the technical problems existing in the prior art by providing an online bleaching agent addition device that can accurately measure the bleaching agent, thus solving the problems of existing solutions.

[0005] To achieve the above objectives, this utility model provides an online bleaching agent addition device capable of precise measurement, comprising a storage tank, a dispensing mechanism on one side of the storage tank, and an addition mechanism at the output end of the dispensing mechanism, wherein: The adding mechanism includes a fixed frame, a mounting ring fixedly connected to the bottom of the fixed frame, a rotating component on the outer top ring of the mounting ring, multiple L-shaped mounting plates fixedly connected to the inner top ring of the mounting ring, a cylinder fixedly mounted on the bottom of the L-shaped mounting plate, an electromagnetic chuck fixedly connected to the output end of the cylinder passing through the L-shaped mounting plate, multiple adding components arranged around the rotating component, and the electromagnetic chuck and the adding components being arranged opposite to each other.

[0006] The beneficial effects of this utility model are: In this precise online bleaching agent addition device, through the cooperation of a rotating ring, cylinder, addition cylinder, and first funnel, when the metering pump pumps equal amounts of precisely metered bleaching agent into the first funnel, the bleaching agent flows into the addition cylinder. Simultaneously, multiple cylinders are activated, driving the corresponding electromagnetic chuck and piston plate to move downwards. The piston plate pushes the bleaching agent inside the addition cylinder, allowing it to flow along the zigzag tube. Finally, the bleaching agent is sprayed from the nozzle output end into the bleaching tank, achieving the purpose of adding bleaching agent to multiple points in the bleaching tank simultaneously. This avoids excessive concentration of bleaching agent, shortens the dispersion time of the bleaching agent, and improves bleaching efficiency.

[0010] The beneficial effect of adopting the above-mentioned further solution is that, through the arrangement of the top block, guide rod and piston plate, when the cylinder output end extends, it drives the electromagnetic chuck and top block to move downward, which in turn drives the guide rod and piston plate to move downward. The piston plate pushes the bleaching agent inside the addition cylinder, so that the bleaching agent can flow along the folded tube and finally be sprayed out from the nozzle output end, thereby achieving the purpose of adding bleaching agent.

[0011] As a further improvement to this technical solution, an L-shaped conduit is fixedly connected to the outer wall of the adding cylinder, and a first funnel is fixedly connected to one end of the L-shaped conduit, with the input end of the first funnel pointing vertically upward.

[0012] The beneficial effect of adopting the above-mentioned further solution is that, through the setting of the first funnel and the L-shaped conduit, when the bleaching agent in the storage tank is taken out by the liquid dispensing mechanism, a certain amount of bleaching agent enters the first funnel and flows down along the L-shaped conduit into the addition cylinder, thereby achieving the purpose of adding bleaching agent into the addition cylinder.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 As shown, this embodiment provides an online bleaching agent addition device capable of precise measurement, including a storage tank 1, a dispensing mechanism 2 on one side of the storage tank 1, and an addition mechanism 3 at the output end of the dispensing mechanism 2, wherein: The adding mechanism 3 includes a fixed frame 31, which is installed above the bleaching tank. A mounting ring 32 is fixedly connected to the bottom of the fixed frame 31. A rotating component 33 is provided on the outer top ring of the mounting ring 32. Multiple L-shaped mounting plates 34 are fixedly connected to the inner top ring of the mounting ring 32. The multiple L-shaped mounting plates 34 are evenly distributed in a ring. A cylinder 35 is fixedly installed at the bottom of the L-shaped mounting plate 34. The cylinder 35 is of model SC40. An electromagnetic chuck 36 is fixedly connected to the output end of the cylinder 35 through the L-shaped mounting plate 34. The electromagnetic chuck 36 is of model X21-500. Multiple adding components 37 are provided around the rotating component 33. The electromagnetic chuck 36 and the adding components 37 are arranged opposite to each other.

[0024] Furthermore, the multiple additives 37 have the same structure. Each additive 37 includes a mounting frame 371. One end of the mounting frame 371 is connected to the rotating component 33. An additive cylinder 372 is fixedly connected to the inner side of the mounting frame 371. A bend tube 373 is fixedly connected to the bottom end of the additive cylinder 372. A nozzle 374 is fixedly connected to the output end of the bend tube 373. The output end of the nozzle 374 is vertically downward. When bleaching agent is added to the bleaching tank through the additive cylinder 372, the bend tube 373, and the nozzle 374, the bleaching agent leaves the additive cylinder 372, flows along the bend tube 373, and finally sprays out from the output end of the nozzle 374. The bleaching agent is injected into the depth of the bleaching tank, thus achieving the purpose of adding bleaching agent.

[0025] Furthermore, a guide rod 375 is connected through the top of the adding cylinder 372, and a top block 376 is fixedly connected to the top of the guide rod 375. The top block 376 is made of a ferromagnetic material, such as steel. The top of the top block 376 abuts against the bottom of the electromagnetic chuck 36. A piston plate 377 is fixedly connected to the bottom of the guide rod 375. The outer wall of the piston plate 377 slides against the inner wall of the adding cylinder 372. A rubber ring 3710 is fixedly connected at the connection between the piston plate 377 and the adding cylinder 372. When the piston plate 377 slides along the inner wall of the adding cylinder 372, the rubber ring 3710 has a certain elasticity, which increases the sealing between the piston plate 377 and the adding cylinder 372, achieving... The purpose is to prevent leakage of liquid and gas inside the addition cylinder 372. Moreover, the surface friction of the rubber ring 3710 is relatively large, which can prevent the piston plate 377 from sliding downward when it is located in the upper part of the addition cylinder 372. Through the arrangement of the top block 376, guide rod 375 and piston plate 377, when the output end of the cylinder 35 extends, it drives the electromagnetic chuck 36 and the top block 376 to move downward, which in turn drives the guide rod 375 and piston plate 377 to move downward. The piston plate 377 pushes the bleaching agent inside the addition cylinder 372, so that the bleaching agent can flow along the folded tube 373 and finally be sprayed out from the output end of the nozzle 374 to achieve the purpose of adding bleaching agent.

[0026] Furthermore, an L-shaped conduit 378 is fixedly connected to the outer wall of the adding cylinder 372. One end of the L-shaped conduit 378 is fixedly connected to a first funnel 379. The input end of the first funnel 379 is vertically upward. Through the arrangement of the first funnel 379 and the L-shaped conduit 378, when the liquid outlet mechanism 2 takes out the bleaching agent from the storage tank 1, a certain amount of bleaching agent enters the first funnel 379 and flows downward along the L-shaped conduit 378 into the adding cylinder 372, thereby achieving the purpose of adding bleaching agent into the adding cylinder 372.

[0027] Furthermore, the rotating component 33 includes a rotating ring 331, the bottom of which is rotatably connected to the top outer ring of the mounting ring 32. One end of the mounting bracket 371 is fixedly connected to the outer wall of the rotating ring 331. By setting the rotating ring 331, when the rotating ring 331 rotates, it drives the adding cylinder 372 to rotate, which in turn drives the first funnel 379 to rotate, so that the input ends of the multiple first funnels 379 are aligned with the output ends of the liquid dispensing mechanism 2, thereby achieving the purpose of adding bleaching agent into the adding cylinder 372.

[0028] Furthermore, the rotating component 33 also includes an L-shaped fixing plate 332. The bottom end of the L-shaped fixing plate 332 is fixedly connected to the inner ring of the top of the mounting ring 32. A motor 333 is fixedly installed on the inner wall of the L-shaped fixing plate 332. The motor 333 is model YE3-280M-6. A gear 334 is fixedly connected to the output end of the motor 333. An internal gear ring 335 is fixedly connected to the inner wall of the rotating ring 331. The outer wall of the gear 334 meshes with the inner wall of the internal gear ring 335. Through the arrangement of the motor 333, the gear 334 and the internal gear ring 335, when the motor 333 rotates, it drives the gear 334 and the internal gear ring 335 to rotate, thereby driving the rotating ring 331 to rotate, so as to provide power for the rotation of the rotating ring 331.

[0029] Furthermore, the dispensing mechanism 2 includes a mounting base 21. One end of the mounting base 21 is fixedly connected to the outer wall of the storage tank 1. A metering pump 22 is fixedly installed on the top of the mounting base 21. The metering pump 22 is a DJ-Z240 / 0.7 model. The input end of the metering pump 22 is fixedly connected to an inlet pipe 23. One end of the inlet pipe 23 is fixedly connected to the output end of the storage tank 1. The output end of the metering pump 22 is fixedly connected to an outlet pipe 24. One end of the outlet pipe 24 is fixedly connected to a second funnel 25. The first funnel 379 and the second funnel 25 are arranged opposite to each other. Through the arrangement of the metering pump 22, the inlet pipe 23, the outlet pipe 24, and the second funnel 25, when the metering pump 22 is working, the metering pump 22 pumps out bleaching agent from the storage tank 1 and accurately measures the required volume of bleaching agent. The pumped bleaching agent flows through the outlet pipe 24 and the second funnel 25 and falls into the first funnel 379, achieving the purpose of accurately measuring the bleaching agent.

[0030] In summary, the working principle of this solution is as follows: When it is necessary to use this adding device to add bleaching agent to the bleaching tank, first add an equal amount of bleaching agent to each adding cylinder 372, as follows: The motor 333 is started, causing it to rotate at a certain angle, which in turn drives the gear 334 and the internal gear ring 335 to rotate, thereby causing multiple mounting brackets 371 to rotate at a certain angle. This causes the first funnel 379 corresponding to one of the adding cylinders 372 to rotate below the output end of the second funnel 25. Then, the metering pump 22 is started, pumping bleaching agent from the storage tank 1 and accurately measuring the required volume of bleaching agent. The pumped bleaching agent flows through the outlet pipe 24 and the second funnel 25, falling into the first funnel 379. The bleaching agent then flows along the... The bleaching agent flows downward through funnel 379 and L-shaped conduit 378 into addition cylinder 372. At this point, due to atmospheric pressure, the bleaching agent level in addition cylinder 372 is flush with the bleaching agent level in bend-tube 373, and there is a certain space between the bleaching agent level in addition cylinder 372 and piston plate 377, containing a certain amount of air. Then, motor 333 rotates in stages at a certain angle, causing metering pump 22 to pump an equal amount of precisely metered bleaching agent into addition cylinder 372. Then, motor 333 continues to rotate... The rotation moves each top block 376 below the electromagnetic chuck 36. The cylinder 35 is activated as needed, moving the electromagnetic chuck 36 until its bottom contacts the top block 376. At this point, the electromagnetic chuck 36 is activated to create an attraction force, firmly adhering to the top block 376. When bleaching agent needs to be added to the bleaching tank online, the cylinder 35 is activated to extend it quickly, moving the electromagnetic chuck 36 and top block 376 downwards. This causes the piston plate 377 and rubber ring 3710 to adhere to the inside of the addition cylinder 372. As the piston plate 377 slides downwards and passes through the outlet of the L-shaped conduit 378, a sealed space is formed between the piston plate 377 and the bleaching agent liquid surface. The piston plate 377 continues to move downwards, pushing the bleaching agent inside the addition cylinder 372, allowing the bleaching agent to flow along the folded tube 373. In addition, the air in the sealed space formed between the piston plate 377 and the bleaching agent liquid surface also enters the folded tube 373 until most of the bleaching agent is pushed out of the folded tube 373. Finally, the bleaching agent is sprayed out from the output end of the nozzle 374 into the bleaching tank.
