Description

Technical Field

[0001] The utility model relates to the technical field of chemical feeders, in particular to a chemical feeder with an anti-splashing structure. Background Art

[0002] Chemical safety refers to a series of activities carried out during the chemical production process to prevent and reduce accidents and protect personnel safety and environmental health through scientific management and technical measures. A chemical feeder is a device used to add raw materials to reactors or other equipment in chemical production. It can adapt to the feeding requirements of raw materials of different specifications and types, realize the automation of the entire process, and seamlessly integrate with other production equipment. The mixing barrel is a very common member of the chemical feeder.

[0003] In order to feed the mixed raw materials into the reactor, a chemical feeder is needed for assistance. First, the liquid raw materials are fed into the mixing barrel through the liquid inlet pipe, and then the solid raw materials are fed into it through the opening at the top of the mixing barrel. The driving motor is then started to drive the stirring rod to rotate, so that the solid raw materials and the liquid raw materials are evenly mixed. After that, the mixed raw materials are fed into the reactor through the discharge pipe for chemical production. However, in the process of mixing chemical raw materials, raw materials need to be continuously added to the mixing barrel. However, when the solid raw materials are fed into the mixing barrel, they are likely to cause liquid to splash everywhere when they collide with the liquid raw materials and the water flow, which poses certain safety hazards and thus affects the use of the chemical feeder.

[0020] See also Figures 1-6The utility model provides a technical solution: a chemical feeder with an anti-splash structure, comprising a mixing barrel 1, a driving motor 2 and a stirring rod 3. The middle part of the top of the mixing barrel 1 is connected to the driving motor 2 through a support plate, and the output end of the driving motor 2 is connected to the stirring rod 3. The bottom end of the mixing barrel 1 is connected to a discharge pipe 4 on both sides, and the inner wall of the mixing barrel 1 is connected to the liquid inlet pipe 5 through a mounting seat. The outer wall of the mixing barrel 1 is provided with a protective mechanism 6, and the protective mechanism 6 includes a protective barrel 601 connected to the mixing barrel 1, the top end of the outer wall of the driving motor 2 is connected to a guide seat 602 through a column, a support platform 603 is welded to the middle part of the outer wall of the mixing barrel 1, and a servo motor 604 is installed on one side of the bottom end of the support platform 603, and the output end of the servo motor 604 is connected to a first synchronous gear 605, and the first synchronous gear 605 is connected to a second synchronous gear 607 through a synchronous toothed belt 606; a first threaded rod 608 is welded to the top of the first synchronous gear 605, and the second synchronous gear 607 is connected to the second synchronous gear 607 through a synchronous toothed belt 606; a first threaded rod 608 is welded to the top of the first synchronous gear 605, and a second threaded rod 608 is welded to the top of the first synchronous gear 605. A second threaded rod 610 is welded to the top of the second synchronous gear 607; the outer wall of the first threaded rod 608 is threadedly connected to the first threaded cylinder 609, and the outer wall of the second threaded rod 610 is threadedly connected to the second threaded cylinder 611; a limiting seat 612 is welded to the middle of the outer wall of the first threaded cylinder 609 and the second threaded cylinder 611, and the tops of the first threaded cylinder 609 and the second threaded cylinder 611 are both connected to the protective cylinder 601; a fixed rod 613 is slidably connected inside the limiting seat 612, and the bottom end of the fixed rod 613 is welded to the support platform 603; the bottom end of the second synchronous gear 607 is connected to the support platform 603 through a bearing seat, and the bottom end of the stirring rod 3 is connected to the mixing cylinder 1 through a bearing seat; the liquid inlet pipe 5 and the mounting seat are in sliding connection, and the mixing cylinder 1 and the protective cylinder 601 are in sliding connection. The interior of the second synchronous gear 607 is connected to the synchronous toothed belt 606, the guide seat 602 is conical, and the outer wall of the liquid inlet pipe 5 is connected to the protective cylinder 601.

[0021] During specific implementation, in the process of feeding raw materials into the reactor through the chemical feeder, in order to prevent the liquid caused by the collision between solid and liquid from splashing out of the mixing barrel 1, since the bottom end of the liquid inlet pipe 5 is located inside the mixing barrel 1, when the liquid material is transported through the liquid inlet pipe 5, the liquid material will directly enter the bottom end of the inner wall of the mixing barrel 1, and then the liquid chemical raw materials can be transported smoothly. Then, the servo motor 604 on the support platform 603 is started, and since the output end of the servo motor 604 is connected to the first synchronous gear 605, the servo motor 604 starts to drive the first synchronous gear 605 to rotate, and since the first synchronous gear 605 is connected to the second synchronous gear 607 through the synchronous toothed belt 606, when the first synchronous gear 605 rotates, it will drive the second synchronous gear 607 to rotate together through the synchronous toothed belt 606. Then, the first synchronous gear 605 rotates to drive the first threaded rod 608 to rotate, and the second synchronous gear 607 rotates to drive the second threaded rod 610 to rotate;

[0022] Since the first threaded rod 608 is threadedly connected to the first threaded cylinder 609, and the second threaded rod 610 is threadedly connected to the second threaded cylinder 611, the rotation of the first threaded rod 608 causes the first threaded cylinder 609 to move upward, and the rotation of the second threaded rod 610 causes the second threaded cylinder 611 to move upward. Then, the upward movement of the first threaded cylinder 609 and the second threaded cylinder 611 generates an upward thrust on the protective cylinder 601, causing the protective cylinder 601 to move upward. Moreover, since the outer walls of the first threaded cylinder 609 and the second threaded cylinder 611 are both connected to the limiting seat 612, the limiting seat 612 slides along the fixing rod 613, thereby guiding the movement of the first threaded cylinder 609 and the second threaded cylinder 611, causing the protective cylinder 601 to move upward stably.

[0023] Until the protective cylinder 601 moves to the specified height, it blocks the area around the opening above the mixing cylinder 1. When the fixed material collides with the liquid material in the mixing cylinder 1, causing liquid splashing, it is blocked by the protective cylinder 601 to prevent the chemical liquid from splashing everywhere and increasing safety hazards. In addition, when solid chemical materials are added, because they are conical with the guide seat 602, the solid chemical materials that collide with the guide seat 602 will be buffered, thereby reducing the height of the liquid splashing when the solid material collides with the liquid material, thereby facilitating buffering and preventing liquid splashing when the chemical feeder is in use.

[0024] To sum up, when this chemical feeder with an anti-splash structure is used, the liquid raw material is first fed into the mixing barrel 1 through the liquid inlet pipe 5, and then the solid raw material is fed into it through the opening at the top of the mixing barrel 1, and then the drive motor 2 is started to drive the stirring rod 3 to rotate, so that the solid raw material and the liquid raw material are evenly mixed, and then the mixed raw materials are fed into the reactor through the discharge pipe 4 for chemical production. This is the existing technology and will not be elaborated on here. The guide seat 602 in the protective mechanism 6 is used to reduce the splash height of the liquid during solid-liquid collision, and the protective cylinder 601 is moved up to a specified height. Then, when the collision of the solid and liquid causes liquid splashing, it is blocked by the protective cylinder 601, thereby preventing the chemical liquid from splashing everywhere and increasing safety hazards. The content not described in detail in this description belongs to the existing technology known to professional and technical personnel in this field.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
