Description

Technical Field

[0001] This utility model relates to the field of coupling agent production technology, specifically to a vertical mixing machine for coupling agent production. Background Technology

[0002] Coupling agents are organosilicon compounds with reactive groups that can bind to both inorganic and organic materials. They are widely used in the coatings, rubber, and pigment industries. During production, variations in reaction conditions, crystallization rates, or drying processes can lead to uneven component distribution within batches. To ensure batch uniformity and eliminate component differences, the coupling agent needs to be mixed in a vertical mixer before packaging, transportation, and sale. However, existing vertical mixers often have discharge ports designed on the side wall of the mixing tank's cone bottom, rather than at the lowest point, resulting in incomplete discharge and material residue at the bottom. Furthermore, the single mixing method fails to effectively address issues of material agglomeration and stratification.

[0003] Chinese patent CN109483757B discloses a vertical mixer for producing plastic shells with high unloading function. It includes a mixing drum, a support frame, a drive motor, a feeding hopper, an unloading drum, a scraping device, and a control box. This invention uses a motor on a braking mechanism to move the two ends of the sliding connecting frame along the lead screw and slide bar, and pushes the scraper to move along the rack mechanism. The push rod follows the guide wheel to smoothly discharge the material. Finally, the scraper moves and scrapes the material inside the drum according to the extension of the push rod, so as to scrape and discharge the remaining material in the drum. Although this patent can solve the problem of material residue, the scraping device it uses has a complex structure and a single mixing method, resulting in poor mixing uniformity. Summary of the Invention

[0004] The main objective of this invention is to overcome the defects of the prior art and provide a vertical mixing machine for the production of coupling agents.

[0005] To achieve the above objectives, this utility model proposes a vertical mixing machine for coupling agent production, comprising a tank and a mixing assembly. The mixing assembly is mounted on the tank, the lower part of which is conical. A discharge port is provided on the side wall of the conical bottom of the tank. The bottom of the conical bottom of the tank is connected to a first feeding cylinder, and the bottom of the first feeding cylinder is connected to a feed hopper. A second feeding cylinder is provided inside the tank. The first and second feeding cylinders are coaxially arranged with a gap between them. The mixing assembly includes a stirring shaft, a drive motor, a first spiral blade, and a second spiral blade. The stirring shaft is rotatably mounted on the central axis of the first and second feeding cylinders. The output end of the drive motor is connected to one end of the stirring shaft. The first spiral blade is located on the outer periphery of the stirring shaft, and the second spiral blade is connected to the stirring shaft. The spiral diameter of the second spiral blade gradually increases from bottom to top and maintains a uniform gap with the inner wall of the conical bottom of the tank.

[0006] In a further optimized technical solution, the lower section of the second spiral blade is connected to the stirring shaft via several transmission connecting rods, and the upper section of the second spiral blade is connected to a support sleeve rotatably sleeved on the outer periphery of the second feeding cylinder via several support connecting rods.

[0007] In a further optimized technical solution, a circulation port is provided on the side wall corresponding to the feed hopper at the conical bottom of the tank.

[0008] In a further optimized technical solution, a first valve is provided at the circulating material inlet.

[0009] In a further optimized technical solution, the second feeding cylinder is fixed inside the tank by a cylinder support rod, and a gap is reserved between the top of the cylinder and the top cover of the tank for material to fall.

[0010] In a further optimized technical solution, a second valve is provided at the discharge port.

[0011] In a further optimized technical solution, a magnetic frame is provided inside the feed hopper.

[0012] In a further optimized technical solution, a support bracket is fixedly provided on the outer periphery of the tank, the drive motor is fixed on the support bracket, the bottom end of the stirring shaft extends out of the first feeding cylinder, and a driven wheel is provided on the bottom end of the stirring shaft. A drive wheel is provided on the output shaft of the drive motor, and the driven wheel and the drive wheel are connected by a chain or belt for transmission.

[0013] In a further optimized technical solution, a manhole is provided on the top of the tank, and a manhole cover is provided at the manhole.

[0014] In a further optimized technical solution, a transparent viewing window is provided on the outer wall of the tank.

[0015] The beneficial effects of this utility model include: after the material to be stirred enters the bottom of the first feeding cylinder from the feed hopper, it is lifted to the top of the tank by the first spiral blades and falls down in an umbrella shape from the top of the second feeding cylinder. The falling material circulates into the gap between the first and second feeding cylinders, continuously circulating and stirring up and down. At the same time, the second spiral blades push the material upward along the conical bottom of the tank to convect and stir the falling material, preventing the material from accumulating at the bottom, making the material more uniformly mixed, and avoiding the problems of material clumping and stratification. After stirring is completed, the second spiral blades push the material in the conical bottom of the tank upward into the discharge port, ensuring that the material in the tank is discharged cleanly without residue.

[0025] Please see Figures 1 to 4The vertical mixing machine for coupling agent production disclosed in this utility model includes a tank body 1 and a mixing assembly 2. The mixing assembly 2 is mounted on the tank body 1 and is used to mix and stir the materials inside the tank body 1. The lower part of the tank body 1 is conical, and a discharge port 3 is provided on the side wall at the conical bottom of the tank body 1. A second valve 301 is provided at the discharge port 3 to control the opening and closing of the discharge port 3. A first feeding cylinder 4 is vertically connected to the bottom of the conical bottom of the tank body 1, and a feeding hopper 5 is connected to the bottom of the first feeding cylinder 4. A second feeding cylinder 6 is provided inside the tank body 1. The first feeding cylinder 4 and the second feeding cylinder 6 are coaxially arranged and a gap is reserved between them. The mixing assembly 2 includes a stirring shaft. 201, drive motor 202, first spiral blade 203 and second spiral blade 204, stirring shaft 201 is rotatably mounted on the central axis of the first feeding cylinder 4 and the second feeding cylinder 6, that is, on the center line of the tank body 1. The output end of the drive motor 202 is connected to one end of the stirring shaft 201 to drive the stirring shaft 201 to rotate. The first spiral blade 203 is located on the outer periphery of the stirring shaft 201 and matches the inner diameter of the first feeding cylinder 4 and the second feeding cylinder 6. The second spiral blade 204 is connected to the stirring shaft 201. The spiral diameter of the second spiral blade 204 gradually increases from bottom to top and maintains a uniform gap with the inner wall of the conical bottom of the tank body 1. Specifically, the lower section of the second spiral blade 204 is rigidly connected to the stirring shaft 201 through several transmission connecting rods 7 at the gap reserved between the first feeding cylinder 4 and the second feeding cylinder 6, so that after the drive motor 202 drives the stirring shaft 201 to rotate, the first spiral blade 203 and the second spiral blade 204 can rotate synchronously for stirring. The upper section of the second spiral blade 204 is connected to the support sleeve 9 rotatably sleeved on the outer periphery of the second feeding cylinder 6 through several support connecting rods 8, so as to transfer the radial load of the upper end of the second spiral blade 204 to the outer wall of the second feeding cylinder 6, reduce the swing amplitude of the end of the second spiral blade 204, avoid friction with the tank wall, and ensure the uniformity of the cone bottom gap. The tank body 1, the first spiral blade 203, the second spiral blade 204, the first feeding cylinder 4 and the second feeding cylinder 6 are all made of 304 stainless steel.

[0026] In this embodiment, after the material to be stirred enters the bottom of the first feeding cylinder 4 through the feed hopper 5, the first spiral blade 203 lifts the material into the interior of the tank 1 during rotation. The first spiral blade 203 continues to rotate, lifting the material upward along the second feeding cylinder 6 and dropping it in an umbrella shape from the top of the second feeding cylinder 6. The falling material continuously circulates and stirs through the gap between the first feeding cylinder 4 and the second feeding cylinder 6. At the same time, the second spiral blade 204 pushes the material upward along the conical bottom of the tank 1 to convect and stir the falling material, preventing the material from accumulating at the bottom and making the material more evenly mixed, avoiding the problems of material clumping and stratification. In the discharge stage after stirring is completed, the material is discharged from the discharge port 3 to the outside of the tank 1. When the material level in the tank 1 is less than the outlet position of the discharge port 3, the drive motor 202 is started to drive the first spiral blade 203 and the second spiral blade 204 to rotate. During the rotation of the second spiral blade 204, the material in the conical bottom of the tank 1 is pushed upward into the discharge port 3, ensuring that the material in the tank 1 is discharged cleanly without residue.

[0027] In a preferred embodiment, a circulation port 10 is provided on the side wall corresponding to the feed hopper 5 at the conical bottom of the tank 1. A first valve 1001 is provided at the circulation port 10 to control the opening and closing of the circulation port 10. During mixing, by opening the first valve 1001, the material at the conical bottom of the tank 1 is returned to the feed hopper 5, extending the circulation path and preventing the material from accumulating at the bottom due to gravity, thereby further improving the uniformity of mixing.

[0028] In a specific example, the second feeding cylinder 6 is fixed to the inner wall of the tank 1 by a cylinder support rod 11, and a gap is reserved between the top of the cylinder and the top cover of the tank 1 for material to fall. The second feeding cylinder 6 is supported by the cylinder support rod 11, and multiple sets of cylinder support rods 11 are provided to ensure that the second feeding cylinder 6 is coaxial with the stirring shaft 201, avoiding eccentric shaking caused by centrifugal force during the stirring process. The top gap provides sufficient diffusion space for the material, so that the material is thrown out from the top of the second feeding cylinder 6 and forms an umbrella-shaped scattering, increasing the contact area with the rising material and enhancing convective mixing.

[0029] In a preferred embodiment, a magnetic frame 501 is provided inside the feed hopper 5. The magnetic frame 501 is composed of multiple high-strength magnetic rods arranged in parallel. When the coupling agent powder / particles pass through the feed hopper 5, magnetic impurities such as iron filings, rust residue, and metal dust are adsorbed by the magnetic frame 501, preventing them from entering the tank 1 for stirring and mixing, thus protecting equipment safety and improving product quality.

[0030] In a specific example, a support bracket 12 is fixedly installed on the outer periphery of the tank body 1. The drive motor 202 is fixed to the bottom of the support bracket 12. The bottom end of the stirring shaft 201 extends to the outside of the first feeding cylinder 4. A driven wheel 205 is provided on the bottom end of the stirring shaft 201. A drive wheel 206 is provided on the output shaft of the drive motor 202. The driven wheel 205 and the drive wheel 206 are connected by a chain or belt 207. The drive motor 202, drive wheel 206, and driven wheel 205 are located at the bottom of the tank body 1 instead of at the top, which increases the convenience of maintenance. A manhole 101 is provided at the top of the tank body 1. A manhole cover 102 is provided at the manhole 101. The manhole 101 facilitates maintenance personnel to enter the interior of the tank body 1 for work. When stirring is in progress, the manhole cover 102 can seal the manhole 101. A transparent window 103 is provided on the outer wall of the tank body 1, which allows for easy observation of the internal materials.
