Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of chemical production, and in particular relates to raw material pretreatment equipment for chemical production. Background Art
[0002] In the chemical production industry, raw materials are pretreated to ensure production progress and efficiency, thereby speeding up subsequent production and processing. Pretreatment often focuses on stirring and mixing. Existing pretreatment equipment often uses a paddle structure for mixing operations. However, when handling the stirring and mixing of highly viscous non-Newtonian fluids such as resins, the paddle structure encounters extremely high resistance at startup, and the paddle is easily damaged when speeding up, thus affecting production safety. Summary of the Invention
[0003] In view of this, the present invention discloses a raw material pretreatment device for chemical production, which aims to solve the problem that the existing pretreatment equipment is easily damaged when stirring and mixing high-viscosity non-Newtonian fluids.
[0004] In order to achieve the above object, the present invention provides the following technical solutions:
[0005] A raw material pretreatment equipment for chemical production, including a shell, a vertically arranged main shaft is rotatably connected to the bottom of the shell, a number of internally hollow and annular mounting discs are coaxially fixed on the main shaft, a support disc body is provided in the mounting disc body and is coaxially connected to the main shaft, a number of coaxial annular grooves are provided on the upper and lower end surfaces of the support disc body, annular supports are vertically slidably provided in the grooves, a driving mechanism for driving the supports to move vertically is provided on the support disc body, a coaxial annular plate is rotatably connected to the top of the support; a number of annular grooves corresponding to the grooves are provided on the upper and lower end surfaces of the mounting disc body, a number of support parts for supporting the annular grooves are reserved between the two sides of the annular grooves, and a number of discharge barrels are connected to the side walls of the mounting disc body.
[0006] In this solution, the raw materials to be processed are placed into the shell. The support pushes the annular plate against the inner wall of the shell, sealing the annular groove. The rotation of the main shaft then drives the mounting disc to rotate, providing initial stirring. Compared to conventional paddle structures, the mounting disc in this solution has a stronger torque resistance and is less susceptible to damage. As the mounting disc rotates, the portion of raw materials in contact with the mounting disc contacts the annular plate. The viscosity of the raw materials drives the annular plate to rotate in the opposite direction relative to the mounting disc, reducing the resistance exerted by this portion of the non-Newtonian fluid raw materials. This reduces the interaction force between the mounting disc and the non-Newtonian fluid, thereby enhancing the mounting disc's torque resistance. When the rotation speed of the mounting disc increases, the drive mechanism drives the support toward each other, exposing the annular groove on the annular plate. After the raw materials flow into the mounting disc, centrifugal force ejects them from the discharge barrel, causing the raw materials to circulate back and forth, achieving mixing of the non-Newtonian fluid raw materials through flow impact mixing.
[0007] Furthermore, an annular rubber ring is provided on the support portion, a force-bearing protrusion is hinged on the rubber ring, and a torsion spring is provided at the hinge. The force-bearing protrusions are all inclined toward the rotation direction of the mounting disc body, and a receiving groove for accommodating the force-bearing protrusion is provided on the rubber ring.
[0008] In this solution, when the mounting disc rotates, the force exerted by part of the non-Newtonian fluid raw material contacts the force-bearing protrusion, and the force-bearing protrusion drives the rubber ring to rotate, thereby reducing the resistance exerted by the raw material on the support part and preventing it from breaking. In addition, the torsion spring is used to reduce the resistance exerted on the force-bearing protrusion and prevent it from breaking. The receiving groove is used when the force-bearing protrusion contacts the annular plate, and the force-bearing protrusion is squeezed into the receiving groove by the annular plate to facilitate the rotation of the rubber ring. At the same time, the force-bearing protrusion can increase the disturbance of the raw material and further accelerate the mixing efficiency of the raw material.
[0009] Furthermore, the annular plate is provided with a plurality of hinged force-bearing plates, and a torsion spring is provided at the hinge. The force-bearing plates are all inclined toward the rotation direction of the mounting disk body; the outer surface of the rubber ring is provided with a pressure groove for the force-bearing plates to pass through, and the pressure groove is staggered with the force-bearing protrusions.
[0010] The force between the raw material and the annular plate is strengthened by the force-bearing plate, so that the raw material drives the annular plate to rotate in the opposite direction.
[0011] Furthermore, a number of limit grooves are provided on both side walls of the groove, and a number of limit rods corresponding to the limit grooves are provided on the inner and outer side walls of the annular plate; the support disc body is rotatably connected to the main shaft, and a notch is provided on the side wall of the main shaft that is opposite to the support disc body, and a horizontally arranged transmission gear is rotatably connected to the notch, and teeth meshing with the transmission gear are provided on the inner wall of the support disc body, and a gear shaft rotatably connected to the bottom of the shell is provided inside the main shaft, and the gear shafts are all meshed with the transmission gear, and the gear shaft and the main shaft rotate in the same direction at a differential speed.
[0012] In this solution, since the gear shaft and the main shaft rotate in the same direction with a differential speed, the gear shaft rotates relative to the main shaft, and the gear shaft cooperates with the transmission gear to drive the support disc body and the mounting disc body to rotate synchronously in the opposite direction, which is beneficial to the rotation of the annular plate in the initial rotation condition, thereby helping to reduce the resistance; when the support drives the annular plate to move toward each other, the limit rod on the annular plate is inserted into the limit groove, causing the annular plate and the support disc body to move synchronously. At this time, the annular plate and the force plate rotate in the opposite direction relative to the mounting disc body, applying turbulence to the raw materials inside the mounting disc body, further accelerating the mixing rate of the raw materials.
[0013] Furthermore, a plurality of sliding holes are provided on the outer wall of the mounting disc, the discharging cylinder is slidably connected to the corresponding sliding holes, and a reset elastic member is provided between the discharging cylinder and the sliding holes.
[0014] Initially, the discharge barrel is submerged in the mounting disc to prevent the discharge barrel from receiving excessive resistance from the raw materials during initial rotation; when the speed of the rotating mounting disc increases, the discharge barrel slides out under the action of centrifugal force, which is conducive to the discharge of the raw materials.
[0015] Furthermore, the inner diameter of the discharge barrel gradually increases in a direction away from the mounting disc.
[0016] Other advantages, objectives and features of the present invention will be described in the following description and will be apparent to those skilled in the art to some extent, or those skilled in the art can be taught from the practice of the present invention. The objectives and other advantages of the present invention can be realized and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0023] like Figures 1 to 4 As shown:
[0024] A raw material pretreatment equipment for chemical production includes a shell 1, a main shaft 2 is vertically arranged at the bottom center of the shell 1, the main shaft 2 is rotatably connected to the bottom of the shell 1, and the main shaft 2 is driven by an external motor (conventional technical means, so not drawn in the figure), a plurality of hollow and annular mounting discs 3 are coaxially welded on the main shaft 2, a support disc 4 coaxially connected to the main shaft 2 is arranged in the mounting disc 3, and a plurality of coaxial annular grooves are opened on the upper and lower end surfaces of the support disc 4, annular supports 5 are vertically slidably arranged in the grooves, a driving mechanism for driving the support 5 vertical movement is provided on the support disc 4, and a coaxial annular plate 6 is rotatably connected to the top of the support 5; a plurality of annular grooves corresponding to the grooves are opened on the upper and lower end surfaces of the mounting disc 3, and a plurality of support parts 7 for supporting the annular grooves are reserved between the two sides of the annular grooves, and a plurality of discharge barrels 8 are connected on the side walls of the mounting disc 3.
[0025] In this embodiment, the raw material to be processed is placed into the housing 1. The support 5 then pushes the annular plate 6 against the inner wall of the housing, sealing the annular groove. The rotation of the main shaft 2 then drives the mounting disc 3 to rotate, providing initial stirring. Compared to conventional paddle structures, the mounting disc 3 in this embodiment has greater torque resistance and is less susceptible to damage. As the mounting disc 3 rotates, the portion of the raw material in contact with the mounting disc 3 comes into contact with the annular plate 6. The viscosity of the raw material drives the annular plate 6 to rotate in the opposite direction relative to the mounting disc 3, reducing the resistance exerted by this portion of the non-Newtonian fluid. This reduces the interaction force between the mounting disc 3 and the non-Newtonian fluid, thereby enhancing the mounting disc 3's torque resistance. When the rotation speed of the mounting disc 3 increases, the drive mechanism drives the support 5 toward each other, exposing the annular groove of the annular plate 6. After the raw material flows into the mounting disc 3, centrifugal force ejects the raw material from the discharge barrel 8, causing the raw material to circulate back and forth, achieving mixing of the non-Newtonian fluid raw material through flow impact mixing.
[0026] In this embodiment, an annular rubber ring 9 is provided on the support portion 7, a force-bearing protrusion 10 is hinged on the rubber ring 9, and a torsion spring (not shown in the figure) is provided at the hinge. The force-bearing protrusions 10 are all inclined toward the rotation direction of the mounting plate body 3, and a receiving groove for accommodating the force-bearing protrusions 10 is provided on the rubber ring 9.
[0027] In this solution, when the mounting disc 3 rotates, the force exerted by part of the non-Newtonian fluid raw material contacts the force-bearing protrusion 10, and the force-bearing protrusion 10 drives the rubber ring 9 to rotate, thereby reducing the resistance exerted by the raw material on the support portion 7 and preventing it from breaking. In addition, the torsion spring is used to reduce the resistance exerted on the force-bearing protrusion 10 and prevent it from breaking; and the receiving groove is used when the force-bearing protrusion 10 contacts the annular plate 6, and the force-bearing protrusion 10 is squeezed into the receiving groove by the annular plate 6 to facilitate the rotation of the rubber ring 9; at the same time, the force-bearing protrusion 10 can increase the disturbance of the raw material and further accelerate the mixing efficiency of the raw material.
[0028] In this embodiment, the annular plate 6 is provided with a plurality of force-bearing plates 11 hingedly connected, and a torsion spring (not shown in the figure) is provided at the hinge. The force-bearing plates 11 are all inclined toward the rotation direction of the mounting disc 3; the outer surface of the rubber ring 9 is provided with a pressure groove for the force-bearing plates 11 to pass through, and the pressure groove is staggered with the force-bearing protrusions 10.
[0029] The force between the raw material and the annular plate 6 is strengthened by the force-bearing plate 11 so that the raw material drives the annular plate 6 to rotate in the opposite direction.
[0030] In this embodiment, a number of limit grooves 12 are provided on both side walls of the groove, and a number of limit rods 13 corresponding to the limit grooves 12 are welded on the inner and outer side walls of the annular plate 6; the support disc body 4 is rotatably connected to the main shaft 2, and a notch is provided on the side wall of the main shaft 2 that is opposite to the support disc body 4, and a horizontally arranged transmission gear 14 is rotatably connected to the notch, and teeth meshing with the transmission gear 14 are provided on the inner wall of the support disc body 4, and a gear shaft 15 rotatably connected to the bottom of the shell 1 is provided inside the main shaft 2, and the gear shaft 15 is driven by an external motor (conventional technical means, so it is not drawn in the figure), and the gear shafts 15 are all meshed with the transmission gear 14, and the gear shaft 15 and the main shaft 2 rotate in the same direction at a differential speed.
[0031] In this solution, since the gear shaft 15 and the main shaft 2 rotate in the same direction with a differential speed, the gear shaft 15 rotates relative to the main shaft 2, and the gear shaft 15 cooperates with the transmission gear 14 to drive the support disk body 4 and the mounting disk body 3 to rotate synchronously in the opposite direction, which is beneficial to the rotation of the annular plate 6 in the initial rotation condition, thereby helping to reduce the resistance; when the support 5 drives the annular plate 6 to move toward each other, the limiting rod 13 on the annular plate 6 is inserted into the limiting groove 12, so that the annular plate 6 and the support disk body 4 move synchronously. At this time, the annular plate 6 and the force plate 11 rotate in the opposite direction relative to the mounting disk body 3, applying turbulence to the raw materials inside the mounting disk body 3, further accelerating the mixing rate of the raw materials.
[0032] In this embodiment, a plurality of sliding holes are opened on the outer wall of the mounting plate body 3, the discharging cylinder 8 is slidably connected to the corresponding sliding holes, and a reset elastic member is provided between the discharging cylinder 8 and the sliding holes.
[0033] Initially, the discharge barrel 8 is submerged in the mounting disc 3 to prevent the discharge barrel 8 from being subjected to excessive resistance exerted by the raw materials during initial rotation; when the speed of the rotating mounting disc 3 increases, the discharge barrel 8 slides out under the action of centrifugal force, which is conducive to the discharge of the raw materials.
[0034] In this embodiment, the inner diameter of the discharge barrel 8 gradually increases in the direction away from the mounting disc 3, which is conducive to the continuous outward throwing of the raw materials.
[0035] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
