Description

TECHNICAL FIELD

[0001] The utility model belongs to emulsion coating production equipment improvement technical field, especially relates to a multifunctional efficient portable emulsification reaction kettle. BACKGROUND

[0002] The emulsification reaction kettle is a kind of commonly used stirring, emulsification equipment, and it mainly rotates and stirs through the stirring shaft in kettle, to strongly shear, impact, crush and emulsify liquid, so that different component phases are rapidly mixed, dissolved and emulsified, so that originally incompatible oil and water phases are fully mixed and uniformly formed into stable emulsion, and other reaction raw materials can be continuously added to the emulsion in kettle body to perform chemical reaction.This kind of equipment is very common in industrial production and processing field.

[0003] However, the stirring reaction material in the kettle body is easily adhered to the inner cavity wall of the emulsification reaction kettle, such as the observed ointment-like material adhered to the inner cavity wall of the reaction kettle after using the emulsification reaction kettle for a period of time.This aspect can cause loss of material after emulsification reaction and discharging, and the proportion of different raw material components actually participating in emulsification reaction changes, and other materials added into the emulsification reaction kettle for subsequent processing reaction are also polluted and affected.Therefore, the inner cavity of the emulsification reaction kettle is manually cleaned by workers at irregular intervals, which is inconvenient to operate, time-consuming and laborious, and is not conducive to fundamentally solving the problem.

[0004] In addition, many emulsification reaction kettles also have the problem of single stirring mode of material, which leads to unsatisfactory emulsification effect. INVENTION CONTENTS

[0005] To solve the above technical problems, the utility model provides a multifunctional efficient portable emulsification reaction kettle, which comprises a kettle body, a cover body coaxially arranged with the kettle body and detachably and cooperatively installed to cover the top opening of the kettle body,

[0006] A driving motor coaxially arranged with the cover body is fixedly installed on the top of the cover body, a driving rod vertically downward coaxially extended from the driving motor is axially rotatably and cooperatively penetrated through the cover body and extended into the kettle cavity of the kettle body, a driving gear coaxially arranged with the driving rod is fixedly sleeved on the driving rod below the cover body, the driving gear is slid upward and abuts on the horizontal lower surface of the cover body in parallel, a plurality of groups of first stirring paddles are evenly and fixedly arranged on the driving rod below the driving gear along the length direction of the driving rod with intervals, each group of first stirring paddles is composed of a plurality of first stirring paddles evenly distributed at the same horizontal height, each first stirring paddle is extended outward horizontally along the radial direction of the driving rod along the length direction of the first stirring paddle, and the driving motor drives the driving rod to rotate axially so as to drive each first stirring paddle to rotate and stir in the kettle cavity.

[0007] Below the cover, there is an annular rack coaxially arranged with the drive gear and located at the same horizontal height. The drive gear is located in the annular cavity of the annular rack. The vertical inner annular surface of the annular rack is the tooth surface, and the vertical outer annular surface of the annular rack protrudes horizontally outward to form an annular mounting protrusion coaxially arranged with the annular rack. An annular connecting plate coaxially arranged with the annular rack extends vertically downward on the cover. The vertical inner surface of the annular connecting plate is recessed horizontally outward to form an annular mounting groove coaxially arranged with the annular connecting plate. The annular rack fits perfectly into the annular mounting groove through the horizontal outward annular mounting protrusion, thereby enabling the annular rack to be axially rotatably and always coaxially mounted on the cover.

[0008] On the horizontal lower ring surface of the annular rack, several vertically extending mounting brackets are uniformly spaced and fixedly extended downwards along the circumferential direction of the rack. Each mounting bracket extends horizontally outwards along the radial direction of the vessel body in its own width direction. A groove, consistent with the length direction of the mounting bracket, is provided on the side of the mounting bracket facing outwards along the radial direction of the vessel body. The groove opening is horizontally outwards along the radial direction of the vessel body, the bottom of the groove is closed, and the top is open. A sliding rod, consistent with the length direction of the groove, is vertically inserted and installed in the groove. The bottom of the sliding rod is vertically supported at the bottom of the groove, and the top of the sliding rod extends vertically upwards out of the groove to the horizontal lower surface near the cover. The sliding rod can only slide back and forth along the length direction of the groove within its groove. An elastic scraper, a strip-shaped plate consistent with the length direction of the sliding rod, extends radially outwards along the body of the sliding rod and elastically abuts against the inner wall of the vessel body in its own width direction.

[0009] Specifically, the part of the slide bar outside the groove is a mounting plate with the width direction consistent with the radial direction of the vessel body. The mounting plate has a number of mounting holes that penetrate the two surfaces of the mounting plate at intervals along its own length direction (vertical direction). The elastic scraper has through holes that penetrate the two surfaces of the elastic scraper, which are aligned with the mounting holes. The bolts are simultaneously fitted through the corresponding mounting holes and through holes, and then tightened by the nuts, thereby achieving parallel fit and fixation between the elastic scraper and the slide bar.

[0010] In addition, a number of second stirring blades are evenly arranged at intervals along the length of the mounting frame on the side away from the elastic scraper. Each second stirring blade extends horizontally inward from the mounting frame along the radial direction of the vessel body along its own length. The second stirring blades and the first stirring blades are alternately arranged in the height direction (vertical direction).

[0011] A vertically oriented transmission gear is installed in the annular cavity of the ring rack below the cover. The transmission gear can rotate axially through the limiting shaft and slides upward parallel to the surface of the cover. The transmission gear is located between the tooth surfaces of the drive gear and the ring rack and meshes with both the drive gear and the ring rack.

[0012] The drive motor drives the drive rod to rotate axially to drive the first stirring paddle to rotate and stir, while also driving the drive gear to rotate axially synchronously. Under the meshing transmission of the transmission gear, the drive gear further drives the ring rack to rotate axially in the opposite direction to the drive gear, thereby driving the second stirring paddle to rotate and stir synchronously in the opposite direction to the first stirring paddle, and the elastic scraper to scrape and clean the inner wall of the vessel.

[0013] The lid has an opening that is vertical in the axial direction and connects the upper and lower horizontal surfaces of the lid. This opening allows the vessel cavity to be connected to the outside when the lid is fitted to cover the vessel. The vertical opening is projected horizontally outward from the bottom surface of the vessel cavity and is close to the inner wall of the vessel cavity. A sealing cover is fitted on the lid to seal the opening. The lower horizontal surface of the sealing cover is flush with the lower horizontal surface of the lid. When the annular rack rotates axially until the sliding rod with the elastic scraper is fixedly installed reaches directly below the opening, the sliding rod can smoothly pass vertically upward through the open opening and leave the vessel cavity.

[0014] A discharge pipe extends vertically downward from the bottom of the vessel body and is connected to the vessel cavity. A valve is installed on the discharge pipe to control the opening and closing of the discharge pipe. Attached Figure Description

Detailed Implementation

[0019] It should be noted that the terms "horizontal" and "vertical" used in the description of this application refer to the radial direction of the vessel body, and "inner" and "outer" refer to the direction toward or away from the geometric center of a specific component, respectively. These are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the present invention.

[0020] As shown in the attached figure, the multifunctional, efficient and convenient emulsification reactor of this utility model first includes a reactor body 1 with a vertical axis and a cover body 2 that is coaxial with the reactor body 1 and can be detachably installed to cover the top opening of the reactor body 1. The reactor body 1 is suspended and stably placed above the ground by several support legs (not shown in the attached figure). A discharge pipe 11 extends vertically downward from the bottom of the reactor body 1, is coaxial with the reactor body 1 and is connected to the reactor cavity of the reactor body 1. A valve (not shown in the attached figure) is provided on the discharge pipe 11 to control the opening and closing of the discharge pipe 11.

[0021] A drive motor 3, coaxially arranged with the cover 2, is fixedly installed on the top of the cover 2. The drive rod 31, which extends vertically downward and coaxially with the drive motor 3, can rotate axially and coaxially cooperates to pass through the cover 2 and extend into the vessel cavity of the vessel body 1. A drive gear 32, coaxially arranged with the drive rod 31, is fixedly installed on the drive rod 31 below the cover 2. The drive gear 32 is parallel to the surface and faces upward and close to the horizontal lower surface of the cover 2. Three sets of first stirring paddles 33 are uniformly fixedly arranged on the drive rod 31 at intervals along the length direction of the drive rod 31 below the drive gear 32. Each set of first stirring paddles 33 consists of two first stirring paddles 33 evenly distributed at the same horizontal height. Each first stirring paddle 33 extends horizontally outward from the drive rod 31 along its own length direction. That is, the included angle between the two first stirring paddles 33 in each set of first stirring paddles 33 is 180°. The drive motor 3 drives the drive rod 31 to rotate axially, thereby driving each first stirring paddle 33 to rotate and stir horizontally in the vessel cavity.

[0022] Below the cover 2, there is an annular rack 21 coaxially arranged with the drive gear 32 and located at the same horizontal height. The drive gear 32 is located in the annular cavity of the annular rack 21. The vertical inner annular surface of the annular rack 21 is the tooth surface. The vertical outer annular surface of the annular rack 21 protrudes outward in a horizontal direction to form an annular mounting protrusion 211 coaxially arranged with the annular rack 21. An annular connecting plate 25 coaxially arranged with the annular rack 21 extends vertically downward on the cover 2. The vertical inner surface of the annular connecting plate 25 is recessed outward in a horizontal direction to form an annular mounting groove 251 coaxially arranged with the annular connecting plate 25. The annular rack 21 fits perfectly into the annular mounting groove 251 through the annular mounting protrusion 211 in a horizontal outward direction (to avoid the movement of the annular rack 21 in the vertical or horizontal direction), thereby realizing that the annular rack 21 can be axially rotated and always coaxially mounted on the cover 2.

[0023] On the lower horizontal ring surface of the annular rack 21, three vertically extending rectangular mounting brackets 22 are uniformly spaced and fixedly fixed downwards along the circumferential direction of the rack 21. The bottom of each mounting bracket 22 is slightly higher than the bottom of the horizontal cavity of the vessel body 1. Each mounting bracket 22 extends horizontally outwards radially along the vessel body 1 in its own width direction (i.e., the included angle between adjacent mounting brackets 22 is 120°). A groove 221, consistent with the length direction of the mounting bracket 22, is provided on the radially outward side of the mounting bracket 22 along the vessel body 1. The opening of the vessel body 1 is radially and horizontally outward. The bottom of the slide groove 221 is closed, while the top is open. A slide rod 222, which is aligned with the length of the slide groove 221, is vertically inserted into the slide groove 221. The bottom of the slide rod 222 is vertically supported against the bottom of the slide groove 221, while the top of the slide rod 222 extends vertically upward from the slide groove 221 to a horizontal lower surface near the cover body 2. The slide rod 222 can only slide vertically back and forth along the length of the slide groove 221 within its respective slide groove 221. The portion of the body located outside the groove 221 is a mounting plate 2221, which is vertical in length and radially aligned with the vessel body 1 in width. The mounting plate 2221 has a plurality of mounting holes 2222 evenly spaced along its length, penetrating both surfaces. A plastic elastic scraper 223 is detachably and fixedly mounted on the mounting plate 2221. The elastic scraper 223 is a strip-shaped plate aligned with the length of the slide bar 222 (mounting plate 2221), and the elastic scraper 223 is aligned with each mounting hole 2222. A through hole 2231 is provided through both surfaces of the elastic scraper 223 (the through hole 2231 and the mounting hole 2222 are round holes of the same size). The bolt 4 is coaxially fitted through the corresponding mounting hole 2222 and through hole 2231, and then tightened by the nut 5, thereby achieving parallel fit and fixation between the elastic scraper 223 and the slide rod 222 (mounting plate 2221), thereby further allowing the elastic scraper 223 to extend horizontally outward along the radial direction of the vessel body 1 in its own width direction until it elastically abuts against the vertical inner wall of the vessel body 1;

[0024] In addition, two second stirring paddles 224 are provided at intervals along the length of the mounting frame 22 on the side away from the elastic scraper 223. Each second stirring paddle 224 extends horizontally inward from the mounting frame 22 along the radial direction of the vessel body 1 along its own length direction. The second stirring paddles 224 and the first stirring paddle 33 are evenly alternated in the vertical height direction.

[0025] A vertically oriented transmission gear 23 is also installed in the annular cavity of the ring rack 21 below the cover 2. The transmission gear 23 is axially rotatable and coaxially fitted onto the vertically oriented limiting shaft 26. Based on the fixed installation of the limiting shaft 26 on the cover 2, it always slides upward parallel to the horizontal lower surface of the cover 2 (avoiding the movement of the transmission gear 23 in the vertical or horizontal direction). The transmission gear 23 is located between the tooth surfaces of the drive gear 32 and the ring rack 23 and meshes with both the drive gear 32 and the ring rack 21.

[0026] The drive motor 3 drives the drive rod 31 to rotate axially to drive the first stirring paddle 33 to rotate horizontally and stir. At the same time, it also drives the drive gear 32 to rotate axially synchronously. Under the meshing transmission of the transmission gear 23, it further drives the ring rack 21 to rotate axially in the opposite direction to the drive gear 32, thereby driving the second stirring paddle 224 to rotate horizontally in the opposite direction to the first stirring paddle 33 and the elastic scraper 223 to continuously scrape and clean the inner wall surface of the vessel body 1.

[0027] The cover 2 has an opening 24 that is vertical in axis and connects the upper and lower horizontal surfaces of the cover 2. This opening is used to connect the vessel cavity of the vessel 1 with the outside when the cover 2 covers the vessel 1. A sealing cover 27 is installed on the cover 2 to seal the opening 24. The lower horizontal surface of the sealing cover 27 is flush with the lower horizontal surface of the cover 2. The projection of the opening 24 vertically downward onto the bottom surface of the vessel 1 is horizontally outward and close to the inner wall of the vessel 1. When the annular rack 21 is axially rotated until the slide rod 222, which is fitted with an elastic scraper 223, reaches directly below the opening 24, the slide rod 222 can smoothly pass vertically upward through the open opening 24 and leave the vessel cavity.

[0028] Based on the above structure, the emulsification reactor, through the inter-gear design, can achieve synchronous reverse circular motion between the first stirring blade 33 and the second stirring blade 224 with only one drive motor 3, that is, to achieve bidirectional stirring and shearing of the mixture in the reactor body 1. In addition, the first stirring blade 33 and the second stirring blade 224 are alternately arranged in position, which is more conducive to the thorough mixing and uniform emulsification of different component phases in the material.

[0029] Meanwhile, the above operation also drives the elastic scraper 223 to rotate in a circular motion, thereby continuously contacting and scraping the inner wall of the vessel 1. This ensures that the material is scraped off into the emulsion reaction system by the elastic scraper 223 before it has stabilized on the inner wall of the vessel 1. This effectively reduces the adhesion of the material to the inner wall of the vessel 1, improves the yield of the material after emulsification, maintains a more stable ratio between the components in the material during emulsification, and greatly extends the cycle of special cleaning of the inner wall of the vessel 1.

[0030] In the actual cleaning process, it is only necessary to add cleaning water into the emulsification reactor and start the elastic scraper 223 to make a circular motion, which can perform special scraping and cleaning on the inner wall of the reactor body 1 without manual operation, making it more convenient.

[0031] The cover 2 is designed with an opening 24, which is convenient for feeding materials into the vessel 1: after opening the sealing cover 27, the various material components are added into the vessel 1 through the opening 24, and then the sealing cover 27 is closed to seal the vessel. The drive motor 3 is then started to carry out the stirring and emulsification reaction. More importantly, when the outer edge of the elastic scraper 223 is worn to a certain extent and can no longer maintain effective elastic contact with the inner wall of the vessel 1, the elastic scraper 223 can be replaced directly through the opening 24 without removing the cover 2 from the vessel 1: the drive motor 3 slowly drives the elastic scraper 223 to rotate circumferentially until it is approximately located at the opening 24. When directly below, the drive motor 3 stops driving. At this time, the operator on the top surface of the cover 2 can directly pull the slide rod 222 and the elastic scraper 223 that needs to be replaced out of the slide groove 221 through the opening 24. After replacing the new elastic scraper 223, the slide rod 222 can be inserted back into the slide groove 221 along the original path. This is also the reason for the above requirement that "the projection of the opening 24 vertically downward on the bottom surface of the horizontal cavity of the vessel 1 is horizontally outward and close to the inner cavity wall of the vessel 1, so that the slide rod 222 with the elastic scraper 223 fixedly installed can smoothly pass through the opening 24 and leave the vessel cavity vertically upward".
