[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. By setting up a reflux tank, part of the epoxy resin material in the mixing tank is discharged into the reflux tank. The reflux operation can reintroduce the unmixed material at the bottom of the mixing tank, the dead corner of uneven mixing or the sediment into the mixing area, and improve the uniformity of the material by re-mixing. In addition, the gas in the material transported into the reflux tank can be discharged through the exhaust mechanism in the reflux tank.

[0016] 2. The driving mechanism drives the stirring mechanism to operate, so that the stirring rods on the outer arc wall of sleeve shaft 1 and sleeve shaft 2 rotate in opposite directions to speed up the mixing of materials. At the same time, the stirring rods located on the outer circle can also scrape the inner wall of the stirring tank. In addition, for epoxy resin production in some special cases, such as using epoxy resin powder to make epoxy resin coatings, the gap between two adjacent stirring rods with different directions can assist in squeezing and crushing the suspended particles, further enhancing the stirring effect.

[0017] 3. Install a filter at the discharge port of the mixing tank and install a curved scraper at the bottom of the mixing mechanism. Since the viscosity of epoxy resin will increase at low temperatures, for some special cases of epoxy resin production, such as when using epoxy resin powder to make epoxy resin coatings, on the one hand, it prevents unmixed particles from directly entering the discharge pipe, and on the other hand, it helps to break up suspended particles and accelerate the material to pass through the filter into the discharge pipe.

A vertically penetrating channel 1 is provided in the horizontal section of the baffle 1. A vertically penetrating channel 2 is provided at a position close to the channel 1 at the end of the top of the reflux tank 12 away from the discharge pipe 13. The exhaust mechanism includes a valve 1 50 slidably connected to the channel 1 and a valve 2 53 slidably connected to the channel 2. The same driving gear 55 is installed between the valve 1 50 and the valve 2 53. The valve 1 50 and the valve 2 53 are synchronously operated through the driving gear 55.

[0027] A rack rod 52 is fixedly connected to the top of the valve 1 50, and a spring telescopic rod 54 is fixedly connected to the end of the rack rod 52 away from the valve 1 50. A driving gear 55 is meshedly connected to the side of the rack rod 52 away from the discharge pipe 13. The axis of the driving gear 55 and the length direction of the rack rod 52 are not located in the same vertical plane and are perpendicular to each other. The driving gear 55 is fixedly connected to a fixed rotating shaft along the axis direction, and the two ends of the fixed rotating shaft are respectively rotatably connected to the inner arc wall of the reflux tank 12. The side of the driving gear 55 away from the rack rod 52 is meshedly connected to a rack rod 52 of the same structure, and the two rack rods 52 are rotationally symmetrical about the axis of the driving gear 55.

[0028] The top of the rack rod 52 away from the valve 1 50 is fixedly connected with the valve 2 53, and the end of the valve 2 53 away from the rack rod 52 is slidably connected in the channel 2. The longitudinal sections of the channel 1 and the valve 1 50 are I-shaped, and the vertical height of the longitudinal section of the valve 1 50 is greater than the vertical height of the longitudinal section of the channel 1. The longitudinal section of the channel 2 is bullet-shaped, and the cross-sectional radius of the side of the channel 2 away from the baffle 1 is smaller. The longitudinal section of the valve 2 53 is trapezoidal. The valve 1 50 is adapted to the channel 1, and the valve 2 53 is adapted to the channel 2. The sides of the channel 1 and the channel 2 away from each other are fixedly connected with the isolation plate 51.

[0029] It should be noted that a solenoid valve is provided at the connection between the mixing tank 10 and the discharge pipe 13 to facilitate control of the reflux time and rate of the material. When reflux is required, the material in the mixing tank 10 flows into the reflux tank 12 under gravity. The control panel 16 is a control terminal that facilitates the operator to intuitively read data and adjust parameters. No further details will be given here.

[0030] The bottom of the stirring tank 10 and the reflux tank 12 is fixedly connected with a support column for support, the inside of the side wall of the stirring tank 10 is provided with a heating device, and the heating device is electrically connected with the power distribution cabinet 15 and the control panel 16; in a possible embodiment, the heating device is an electric heating device, that is, the inside of the stirring tank 10 is heated by the heating copper pipe laid in the inside of the side wall of the stirring tank 10; due to the stirring effect, the material is continuously turned over to realize uniform heating; the bottom of the baffle one in the reflux tank 12 is provided with a microwave device, which is used to heat the material in the reflux tank 12 and accelerate the discharge of bubbles in the material; the microwave device should be higher than the connection position of the discharge pipe 13 and the reflux tank 12, and direct contact between the material and the microwave device should be avoided during operation;

[0031] The exhaust mechanism is in a closed state in a normal state, that is, the valve one 50 naturally falls down, the top end of the valve one 50 and the top end of the channel one are in close contact with each other, and the top end of the valve two 53 and the top end of the channel two are in close contact with each other; when the valve one 50 is lifted up, the valve two 53 immediately falls down, and at this time the channel one and the channel two are in communication;

[0032] The baffle one is inclined to better guide the gas to gather in the channel one; in a possible embodiment, the top of the reflux tank 12 can be designed as a conical shape, so that the gas is more easily gathered; the inner wall of the bottom of the reflux tank 12 is inclined towards the opening of the reflux tank 12 where the inlet pipe two is located, so as to facilitate the liquid pump to suck the material in the reflux tank 12;

[0033] The double valves of the exhaust mechanism are designed to prevent dust from entering the reflux tank 12 during the end of the exhaust stage; as the gas in the reflux tank 12 is gradually discharged, the internal pressure of the reflux tank 12 gradually decreases, so the flow rate and pressure of the gas discharged from the valve two 53 decrease, and dust is likely to enter during this period; the baffle one can prevent dust from directly falling into the reflux tank 12, and the valve one 50 and the valve two 53 form a double-sealed structure to reduce the influence of the outside on the inside of the reflux tank 12.

[0034] Please refer to Figure 1-5The utility model provides a technical solution: a box body 11 is installed on the top of the stirring tank 10, a stirring mechanism 30 is provided in the stirring tank 10, a driving mechanism 20 is provided in the box body 11, and a power distribution cabinet 15 is fixedly connected to the top of the outer arc wall of the stirring tank 10 on the side away from the reflux tank 12, and a control panel 16 is fixedly connected to the bottom end of the outer arc wall of the stirring tank 10 on the side away from the reflux tank 12. The power distribution cabinet 15 is electrically connected to the control panel 16 and the driving mechanism 20. A liquid pump is installed on the top of the reflux tank 12, and a feed pipe 14 is installed at one end of the liquid pump away from the reflux tank 12. The end of the feed pipe 14 away from the liquid pump is connected to the stirring tank 10, and a feed pipe 2 is installed at the end of the liquid pump close to the reflux tank 12. The end of the feed pipe 2 away from the liquid pump passes through the reflux tank 12, and a horizontal filter screen 42 is installed at the bottom end of the interior of the stirring tank 10, and the filter screen 42 is located above the connection between the discharge pipe 13 and the stirring tank 10;

[0035] The stirring mechanism 30 includes a rotating shaft 31 rotatably connected to the center of the top inner wall of the box body 11, and the driving mechanism 20 includes a motor 21 fixedly connected to the bottom inner wall of the box body 11. The end of the rotating shaft 31 close to the stirring tank 10 passes through the stirring tank 10 and the box body 11. The end of the outer arc wall of the rotating shaft 31 close to the stirring tank 10 is sleeved with a rotating shaft 2 32, and the rotating shaft 2 32 is located in the stirring tank 10. The cross-sectional radius of the end of the rotating shaft 31 away from the box body 11 is greater than the cross-sectional radius of the end of the rotating shaft 31 close to the box body 11. A plurality of chute 1s distributed in a circular array are provided on the outer arc wall of the end of the rotating shaft 31 away from the box body 11, and the length direction of the chute 1 is parallel to the axial direction of the rotating shaft 31.

[0036] It should be noted that the liquid pump is used to assist in transporting the material in the reflux tank 12 back to the mixing tank 10. In addition to being provided with a feed port 1 and a discharge port 2 for installing a discharge pipe 13 and a feed pipe 1 14, the mixing tank 10 is also separately provided with a feed port 2 for feeding before stirring and a discharge port 2 for discharging after stirring (not shown in the figure), and the four do not interfere with the power distribution cabinet 15 and the control panel 16. In order to control the feeding and discharging, solenoid valves are provided in the feed pipe 14, the feed pipe 2 and the discharge pipe 13, and the solenoid valves are electrically connected to the power distribution cabinet 15 and the control panel 16. The rotating shaft 1 31 can be regarded as the splicing of two rotating shafts with different radii, and there is no smooth transition at the boundary.

[0037] The filter screen 42 is used to filter the material about to enter the reflux tank 12 to prevent the unevenly mixed particles generated during stirring from entering the discharge pipe 13. Since the temperature of the discharge pipe 13 is lower than the internal temperature of the stirring tank 10, the epoxy resin on the surface of the particles will instantly cool down and become thicker, thereby blocking the discharge pipe 13.

[0038] See also Figure 1-5The present invention provides a technical solution: the end of the second rotating shaft 32 away from the box body 11 is plugged with a sleeve shaft 1 33, and the sleeve shaft 1 33 is sleeved on the outer arc wall of the rotating shaft 1 31, and a plurality of slots 1 distributed in a ring array are opened on the side wall of the rotating shaft 2 32 close to the sleeve shaft 1 33, and a plurality of card blocks 1 corresponding to and adapted to the slots 1 are fixedly connected on the side wall of the sleeve shaft 1 33 close to the rotating shaft 2 32, and a sleeve shaft 2 34 is sleeved on the end of the outer arc wall of the rotating shaft 1 31 away from the box body 11, and a plurality of card blocks 2 distributed in a ring array are fixedly connected on the inner arc wall of the sleeve shaft 2 34, the slider 1 corresponds to and adapts to the slide groove 1 one by one, and a plurality of stirring rods distributed in a ring array are fixedly connected to the outer arc walls of the sleeve shaft 1 33 and the sleeve shaft 2 34;

[0039] The center of the side wall of the rotating shaft 1 31 away from the box body 11 is fixedly connected with a bolt, and the bolt is threadedly connected to a limit plate 40. The cross-sectional radius of the limit plate 40 is equal to the cross-sectional radius of the outer ring of the sleeve shaft 2 34. Two arc-shaped scrapers 41 are rotationally symmetrically provided on the outer arc wall of the limit plate 40 about the axis of the rotating shaft 1 31 of the limit plate 40. The two arc-shaped scrapers 41 are staggered and the notches are opposite to each other. The ends of the two arc-shaped scrapers 41 that are closer to each other are higher than the ends of the two ends that are farther away from each other. The bottom ends of the arc-shaped scrapers 41 abut against the filter screen 42.

[0040] The end of the rotating shaft 31 away from the mixing tank 10 is fixedly connected to the bevel gear 1 23, and the bevel gear 1 23 is located above the rotating shaft 2 32. The side wall of the rotating shaft 2 32 close to the bevel gear 1 23 is fixedly connected to the bevel gear 2 24. The bevel gear 2 24 is sleeved on the outer arc wall of the rotating shaft 1 31 and the two are rotatably connected to each other. The teeth of the bevel gear 1 23 and the bevel gear 2 24 are arranged opposite to each other, and the same side of the bevel gear 1 23 and the bevel gear 2 24 are meshed with the same active bevel gear 22. The active bevel gear 22 is fixedly connected to the motor 21 on the side wall away from the bevel gear 1 23.

[0041] It should be noted that: sleeve shaft 1 33 is connected to rotating shaft 2 32 through block 1, and sleeve shaft 2 34 is connected to slide groove 1 on rotating shaft 1 31 through slider 1. When the motor 21 drives the driving bevel gear 22 and then drives bevel gear 1 23 and bevel gear 2 24, it will drive rotating shaft 1 31 and rotating shaft 2 32 to rotate coaxially and in opposite directions, and then drive sleeve shaft 1 33 and sleeve shaft 2 34 to rotate coaxially and in opposite directions;

[0042] The limiting plate 40 is used to prevent the second sleeve shaft 34 and the first sleeve shaft 33 from falling off, and the direction of the thread on the bolt is opposite to the working direction of the rotating shaft 1 31 during stirring. When the limiting plate 40 is fully connected with the bolt, the second rotating shaft 32, the second sleeve shaft 34 and the limiting plate 40 are tightly abutted against each other. Furthermore, a ball bearing is provided on the side wall where the second rotating shaft 32 and the first sleeve shaft 33 are close to each other to reduce the friction generated during relative rotation. In a possible embodiment, the first sleeve shaft 33 and the second sleeve shaft 34 are fixedly connected as a whole to prevent the material from seeping through the gap during stirring, causing inconvenience to later cleaning and maintenance, or to avoid feeding too much material at one time.

[0043] The stirring rod is L-shaped, and the horizontal portion of the stirring rod is fixedly connected to the outer arc wall of the sleeve shaft 1 33 or the sleeve shaft 2 34. The vertical portion of the stirring rod fixedly connected to the outer arc wall of the sleeve shaft 1 33 is arranged away from the box body 11, and the vertical portion of the stirring rod fixedly connected to the outer arc wall of the sleeve shaft 2 34 is arranged toward the box body 11. Furthermore, the stirring rod on the outer arc wall of the sleeve shaft 1 33 is divided into an inner and outer layers. The outer layer is in close contact with the inner arc wall of the stirring tank 10 and is used to scrape off the material adhering to the inner wall of the stirring tank 10. The stirring rods in the inner layer are staggered and do not interfere with each other, and the inner and outer stirring rods on the sleeve shaft 1 33 are staggered.

[0044] One end of the curved scraper 41 close to the filter screen 42 is a slope and is almost tangent to the surface of the filter screen 42, that is, the curved scraper 41 scoops up the surface of the filter screen 42 when it rotates. If there are particles stuck in the filter holes of the filter screen 42 at this time, the particles can be cut and crushed. In addition, when the curved scraper 41 rotates, the scooped particles will be guided along its concave surface to the intersection of the two curved scrapers 41, and the large particles will be transported to the center of the filter screen 42. At the same time, the two curved scrapers 41 are in contact with the particles. At this time, under the interaction of the two curved scrapers 41, the particles are no longer guided but cut, and the powder inside the particles with damaged surfaces will be exposed, thereby making the particles smaller.

[0045] Working principle:

[0046] During stirring, the material enters the stirring tank 10 and is stirred for a period of time. Then, the solenoid valve 1 at the bottom of the stirring tank 10 is opened according to the specific situation. The stirred material flows from the filter screen 42 into the discharge pipe 13 and then into the reflux tank 12. During this period, the arc scraper 41 will concentrate the suspended particles blocked on the filter screen 42 to prevent the suspended particles from directly entering the discharge pipe 13. At the same time, the arc scraper 41 can assist in crushing the particles to reduce the diameter of the particles so that they can pass through the filter screen 42. When the material enters the reflux tank 12, since the internal temperature of the reflux tank 12 is still relatively high, the ultrasonic device provided in the reflux tank 12 can heat the material in the reflux tank 12 while accelerating the bursting of bubbles to accelerate the discharge of gas. When the air pressure in the reflux tank 12 is large enough, the valve 1 50 will be pushed open and the valve 2 53 will be opened at the same time. The gas will be discharged to the outside of the reflux tank 12 through the channel 1 and the channel 2.

[0047] Then the liquid pump sends the material in the reflux tank 12 back to the mixing tank 10 through the feed pipe 2 and the feed pipe 1 14 to continue stirring. The uniformity of the material is improved by remixing to avoid product quality problems or material waste caused by uneven stirring.

[0048] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
