Description

Technical Field

[0001] This invention relates to the field of mixing equipment technology, and more specifically, to a mixing device for raw material processing. Background Technology

[0002] Chemical raw materials are raw materials produced using chemical methods. They encompass inorganic chemical products (excluding fertilizers, inorganic pesticides, and inorganic pigments) and various products manufactured primarily using polymer materials in the organic synthesis industry. The processing of chemical raw materials requires the mixing of multiple chemical materials, necessitating the use of mixing equipment specifically designed for chemical raw material processing.

[0003] In related technologies, mixing devices for raw material processing typically use internal stirring rods to mix chemical raw materials. However, the stirring rod structure of traditional mixing devices for raw material processing is simple, the mixing method is simple, and it is easy to make the mixing uneven, which affects the material formation effect. At the same time, there is a problem of low mixing efficiency, resulting in low chemical raw material processing efficiency. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, embodiments of the present invention propose a mixing device for raw material processing. This mixing device can use a drive motor to simultaneously drive multiple uniformly arranged stirring structures to perform stirring operations, thereby increasing the effective stirring area, improving the mixing effect of raw materials, and ultimately improving processing efficiency.

[0006] The mixing device for raw material processing according to an embodiment of the present invention includes: a mixing cylinder having a mixing chamber; and a stirring assembly including a drive motor, a movable rod, a gear ring, and multiple rotating rods. The drive motor is disposed on the top outer end face of the mixing cylinder. The movable rod is vertically inserted into the mixing chamber and connected to the output shaft of the drive motor. Multiple fixed rods extending radially outward and spaced apart circumferentially on the outer circumferential surface of the movable rod are provided. Multiple rotating rods are spaced around the outer circumference of the movable rod. The outer ends of the multiple fixed rods are correspondingly connected to the multiple rotating rods. The rotating rods are rotatable relative to the fixed rods, and a gear disk is provided at the top of the rotating rod. The gear ring is disposed on the inner top wall of the mixing cylinder and surrounds the outer circumference of the movable rod. The multiple gear disks mesh with the gear ring. Each rotating rod has a stirring rod extending radially on its outer circumferential surface.

[0007] In this embodiment of the invention, a mixing device for raw material processing includes a drive motor mounted on the top outer end face of a mixing cylinder. A movable rod is vertically inserted into the mixing chamber and connected to the output shaft of the drive motor. Multiple fixed rods extending radially outward and spaced apart circumferentially on the outer periphery of the movable rod are provided. Multiple rotating rods are spaced around the outer periphery of the movable rod. The outer ends of the fixed rods are correspondingly connected to the rotating rods. Each rotating rod is rotatable relative to the fixed rods, and a gear disc is provided at the top of each rotating rod. A gear ring is mounted on the inner top wall of the mixing cylinder and surrounds the movable rod. On the outer periphery of the rod, multiple gear discs mesh with the gear ring. Each rotating rod has a stirring rod extending radially on its outer peripheral surface. Thus, starting a single drive motor can drive the movable rod to rotate, and the rotation of the movable rod can drive multiple rotating rods on its outer periphery to rotate. When the gear disc at the top of the rotating rod moves along the outer periphery of the gear ring, it will rotate, eventually driving the rotating rod to rotate, and then driving the stirring rod to rotate to achieve stirring and mixing of the raw materials. Therefore, this application can use one drive motor to drive multiple uniformly arranged stirring structures to perform stirring operations, thereby increasing the effective stirring area, improving the mixing effect of raw materials, and ultimately improving processing efficiency.

[0012] In some embodiments, the limiting rods are a plurality of rods arranged at intervals along the circumference of the movable rod, and a plurality of fixing plates are provided on the outer circumferential surface of the movable rod, which are arranged at intervals along the circumference of the movable rod.

Detailed Implementation

[0026] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0027] like Figures 1-8 As shown, the mixing device for raw material processing in this embodiment of the invention includes a mixing cylinder and a stirring assembly.

[0028] Specifically, the mixing cylinder has a mixing chamber, and the stirring assembly includes a drive motor 301, a movable rod 400, a gear ring 302, and multiple rotating rods 601. The drive motor 301 is located on the top outer end face of the mixing cylinder. The movable rod 400 is vertically inserted into the mixing chamber and connected to the output shaft of the drive motor 301. Multiple fixed rods 600 are provided on the outer circumferential surface of the movable rod 400, extending radially outward and spaced apart around the circumference of the movable rod 400. Multiple rotating rods 601 are spaced around the outer circumference of the movable rod 400. The outer ends of the multiple fixed rods 600 are correspondingly connected to the multiple rotating rods 601. The rotating rods 601 are rotatable relative to the fixed rods 600, and the top of the rotating rods 601 is provided with a gear disk 603. The gear ring 302 is located on the inner top wall of the mixing cylinder and surrounds the outer circumference of the movable rod 400. Multiple gear disks 603 mesh with the gear ring 302. Each rotating rod 601 has a stirring rod 602 extending radially on its outer circumferential surface.

[0029] like Figure 5 and Figure 8 As shown, the movable rod 400 has four spaced-apart fixed rods 600 on its outer periphery. Each fixed rod 600 has a vertical rotating rod 601 at its outer end. Each rotating rod 601 has a gear disk 603 at its top. The four gear disks mesh at intervals with the outer periphery of the gear ring 302. A stirring rod 602 is provided on the rod body of the rotating rod 601. When the drive motor 301 rotates, it can drive the movable rod 400 to rotate. The rotation of the movable rod 400 can drive the rotating rod 601 to rotate through the fixed rods 600. When the gear disk 603 at the top of the rotating rod 601 moves along the gears, it will rotate. The rotation of the gear disk 603 can drive the rotating rod 601 to rotate relative to the fixed rods 600, thereby driving the stirring rod 602 to rotate, so as to stir the raw materials in the mixing chamber.

[0030] Therefore, multiple rotating rods 601 are provided on the outer periphery of the movable rod 400, and the multiple rotating rods 601 carrying their equipped stirring rods 602 can perform large-scale stirring in the mixing chamber, thereby improving the mixing uniformity and mixing efficiency.

[0031] In the raw material processing mixing device of this embodiment, a drive motor 301 is disposed on the top outer end face of a mixing cylinder. A movable rod 400 is vertically inserted into the mixing chamber and connected to the output shaft of the drive motor 301. Multiple fixed rods 600 are provided on the outer circumferential surface of the movable rod 400, extending radially outward and spaced apart circumferentially around it. Multiple rotating rods 601 are spaced around the outer circumference of the movable rod 400. The outer ends of the multiple fixed rods 600 are correspondingly connected to the multiple rotating rods 601. The rotating rods 601 are rotatable relative to the fixed rods 600, and a gear disk 603 is provided at the top of the rotating rod 601. A gear ring 302 is disposed on the inner top wall of the mixing cylinder and surrounds the outer circumference of the movable rod 400. All 603 are engaged with the gear ring 302. Each rotating rod 601 has a stirring rod 602 extending radially on its outer circumferential surface. Thus, starting a single drive motor 301 can drive the movable rod 400 to rotate. The rotation of the movable rod 400 can drive the multiple rotating rods 601 on its outer circumference to rotate. When the gear disk 603 at the top of the rotating rod 601 moves along the outer circumference of the gear ring 302, it will rotate, eventually driving the rotating rod 601 to rotate, and then driving the stirring rod 602 to rotate, thereby achieving the mixing of raw materials. Thus, this application can use one drive motor 301 to drive multiple uniformly arranged stirring structures to perform stirring operations, thereby increasing the effective stirring area, improving the mixing effect of raw materials, and ultimately improving processing efficiency.

[0032] In some embodiments, such as Figure 8 As shown, each rotating rod 601 is provided with multiple layers of stirring rods 602 spaced apart in the vertical direction, and each layer of stirring rods 602 includes multiple rods arranged intersectingly. Thus, when the rotating rod 601 rotates, all layers of raw materials in the mixing chamber can be stirred and mixed, and the intersecting rods can increase the stirring area and improve the mixing effect.

[0033] In some embodiments, such as Figure 1 As shown, the mixing cylinder includes a cylinder body 200 and a cover plate. The cover plate is detachably mounted on the top of the cylinder body 200, and a drive motor 301 is mounted on the cover plate. The cylinder body 200 has a mixing chamber. Therefore, when material needs to be added, the cover plate 300 can be detached from the cylinder body 200 and moved upwards, opening the upper end of the cylinder body 200. After material addition is complete, the cover plate 300 is moved downwards to its original position. Figure 6 As shown, the cover 300 includes a top plate and an outer peripheral plate. The bottom of the outer peripheral plate is provided with a positioning groove 303. When the cover 300 is installed with the cylinder 200, the upper end of the cylinder 200 fits in the positioning groove 303.

[0034] In addition, it should be noted that when chemical raw materials are stirred and mixed in the mixing drum, they are prone to adhering to the drum wall, making it difficult to extract some of the chemical raw materials. To address this problem, the mixing device for raw material processing in this application also includes a wall scraping assembly. The wall scraping assembly includes a limiting rod 404, a first connecting plate 405, and a first scraper 406. One end of the limiting rod 404 is movably connected to the outer peripheral surface of the movable rod 400, and the other end extends downward along the radial direction of the movable rod 400. The first connecting plate 405 is movably connected to the limiting rod 404 and is vertically arranged. The first scraper 406 is installed on the first connecting plate 405 and is vertically arranged. When the cover plate is connected to the drum 200, the first scraper 406 contacts the inner wall surface of the drum 200.

[0035] Specifically, such as Figure 6 As shown, four spaced-apart limiting rods 404 are provided on the outer periphery of the movable rod 400. A first connecting plate 405 is installed on the outer end of the limiting rod 404. A first scraper 406 is provided on the first connecting plate 405. When the cover 300 is sealed, the first scraper 406 contacts the inner wall surface of the cylinder 200. When the drive motor 301 starts and drives the movable rod 400 to rotate, the limiting rod 404 can rotate with the movable rod 400, thereby driving the first scraper 406 to sweep along the inner peripheral surface of the cylinder 200 to achieve the wall scraping effect, and avoid the problem of chemical raw materials sticking to the wall of the cylinder 200.

[0036] Furthermore, multiple limit rods 404 are spaced apart in the height direction of the movable rod 400, which can improve the installation stability of the second connecting plate 504.

[0037] In some embodiments, such as Figure 6 and Figure 7 As shown, the mixing device for raw material processing also includes a driving member, a second connecting plate 504, and a second scraper 505. The driving member is connected to the bottom of the movable rod 400 and to the second connecting plate 504. The second connecting plate 504 extends outward along the bottom wall of the cylinder 200. The second scraper 505 is mounted on the second connecting plate 504 and extends outward along the bottom wall of the cylinder 200. When the cover plate is connected to the cylinder 200, the second scraper 505 contacts the bottom wall of the cylinder 200. The outer end of the second connecting plate 504 is movably connected to the lower end of the first connecting plate 405. The driving member is used to drive the second connecting plate 504 to move downward when the cover 300 is separated from the cylinder 200.

[0038] like Figure 6 As shown, there are four second connecting plates 504 arranged at intervals along the circumference of the movable plate, and each second connecting plate 504 is equipped with a second scraper 505. Optionally, there are multiple second connecting plates 504 arranged at intervals along the outer periphery of the movable plate, and the number can be determined according to the requirements and is not limited here.

[0039] It is understandable that when the cover 300 is sealed, the second scraper 505 can contact the bottom wall of the cylinder 200. Then, the rotation of the movable rod 400 can drive the drive component to rotate, which in turn drives the second scraper 505 to rotate and sweep along the bottom wall of the cylinder 200, thus solving the problem of chemical raw material deposition and wall adhesion on the bottom wall.

[0040] In addition, when the cover 300 is disassembled and opened, the driving component drives the second connecting plate 504 to move downward, which in turn drives the first connecting plate 405 to move downward. Since both ends of the limiting rod 404 are movable, as the first connecting plate 405 moves downward, the first connecting plate 405 will retract inward, thereby driving the first scraper 406 to retract inward and separate from the inner peripheral wall of the cylinder 200, so as to facilitate subsequent cleaning of the inside of the mixing cylinder.

[0041] It should be noted that before mixing different chemical raw materials, the mixing cylinder needs to be cleaned. The first scraper 406 and the second scraper 505, which are in contact with the inner wall of the cylinder 200, will form a cleaning dead corner at the contact point. To address this issue, the cover 300 of this application can be disassembled and moved upward to separate the second scraper 505 from the bottom wall of the cylinder 200, thereby solving the problem of cleaning dead corners on the bottom wall. At the same time, the drive frame can drive the first connecting plate 405 to move downward to move the second connecting plate 504 downward and retract inward, thereby separating the second scraper 505 from the peripheral wall and solving the problem of cleaning dead corners on the peripheral wall.

[0042] Furthermore, in some embodiments, such as Figure 7 As shown, the driving component includes a support cylinder 500 and a movable cylinder 501. The support cylinder 500 is vertically arranged and its top is connected to the bottom of the movable rod 400. The movable cylinder 501 is movably sleeved inside the support cylinder 500. An elastic element 502 is provided between the support cylinder 500 and the movable cylinder 501. A support seat 503 is provided on the outer circumferential surface of the movable cylinder 501. The other end of the support seat 503 is movably connected to the inner end of the second connecting plate 504. When the cover plate is connected to the cylinder body 200, the elastic element 502 is in a compressed state and has a force that pushes the movable cylinder 501 downward. Preferably, the elastic element 502 is a spring.

[0043] Specifically, such as Figure 7 As shown, the support cylinder 500 is a polygonal sleeve with an open bottom, and the movable cylinder 501 is a polygonal sleeve with an open top. The movable cylinder 501 is inserted into the support cylinder 500 from the bottom, and a spring is provided inside the movable cylinder 501. The top of the spring abuts against the top wall of the support cylinder 500, and the bottom abuts against the bottom wall of the movable cylinder 501. When the cover 300 is connected and sealed with the cylinder 200, the spring is in a compressed state.

[0044] Furthermore, the bottom opening edge of the support cylinder 500 has an outwardly folded limiting hook plate, and the top opening edge of the movable cylinder 501 has an outwardly folded limiting protrusion 506. When the support cylinder 500 and the movable cylinder 501 move relative to each other to the limit position, the limiting protrusion 506 and the limiting hook plate can stop each other to achieve the anti-detachment function.

[0045] Therefore, when the cover 300 separates and moves upward, the movable rod 400 rises synchronously and drives the support cylinder 500 to rise. Under the thrust of the spring, the movable cylinder 501 descends and drives the support seat 503 to descend. The support seat 503 pulls the first connecting plate 405 down and finally drags the second connecting plate 504 inward to retract, thereby separating the second scraper 505 from the inner wall of the cylinder 200.

[0046] Furthermore, by making the support cylinder 500 and the movable cylinder 501 into polygonal structures, rotational limiting can be achieved. That is, when the movable rod 400 rotates and drives the support cylinder 500 to rotate, the limiting effect of the polygon can drive the movable cylinder 501 to rotate, thereby driving the second scraper 505 to rotate and clean the bottom wall of the cylinder 200.

[0047] In some embodiments, such as Figure 5 As shown, there are multiple limiting rods 404 arranged at intervals along the circumference of the movable rod 400. Multiple fixing plates 402 are provided on the outer circumferential surface of the movable rod 400, arranged at intervals along its circumference. A limiting rod 404 is provided between two adjacent fixing plates 402. Multiple fixing rods 600 and multiple limiting rods 404 are arranged alternately in the circumferential direction of the movable plate, and the fixing rods 600 are installed on the fixing plates 402.

[0048] Furthermore, such as Figure 5 As shown, the fixing plates 402 located on both sides of the limiting rod 404 are a left fixing plate 402 and a right fixing plate 402. A shaft 403 passes through the left fixing plate 402 and the right fixing plate 402, and the limiting rod 404 is rotatably connected to the shaft 403. In other words, the limiting rod 404 is mounted on the fixing plate 402 through the shaft 403. Under the restriction of the rotating shaft, the limiting rod 404 can swing up and down, so that when the second connecting plate 504 pulls the first connecting plate 405, the limiting rod 404 can swing downward to achieve the inward retraction of the first connecting plate 405.

[0049] In some embodiments, such as Figure 1 As shown, a discharge port is provided in the middle of the bottom wall of the cylinder 200, and the bottom wall of the cylinder 200 is a cone shape that gradually tapers towards the discharge port. Therefore, the gradually tapering bottom wall can guide the chemical raw materials to flow towards the discharge port, reducing the probability of wall adhesion and improving discharge efficiency.

[0050] like Figure 1As shown, a discharge pipe 201 is connected to the discharge port, and a valve body 202 is provided on the discharge pipe 201. The opening and closing of the valve body 202 can realize the opening and closing of the discharge pipe 201.

[0051] Preferably, the valve body 202 is a ball valve.

[0052] In some embodiments, Figures 1-4 As shown, the mixing device for raw material processing also includes a support assembly, which includes a base 101, a telescopic member 104, and a connecting frame 102. The bottom of the telescopic member 104 is connected to the base 101, and the top is connected to the connecting frame 102. The connecting frame 102 is connected to the cover 300. The telescopic member 104 can extend and retract to drive the connecting frame 102 to rise and fall. The cylinder 200 is connected to the base 101.

[0053] Specifically, the telescopic component 104 includes a first telescopic component and a second telescopic component, the connecting frame 102 includes a first connecting frame, a second connecting frame and a crossbar 103, the first telescopic component and the second telescopic component are arranged at intervals, the first connecting frame is connected to the top of the first telescopic component and is vertically arranged, the second connecting frame is connected to the top of the second telescopic component and is vertically arranged, the crossbar 103 is connected between the tops of the first connecting frame and the second connecting frame, and the mixing cylinder is located between the first connecting frame and the second connecting frame and is connected to both the first connecting frame and the second connecting frame.

[0054] like Figures 2-4 As shown, the base 101 includes two spaced-apart bottom beams connected by a crossbeam. Each bottom beam has a vertical fixed pipe 100 at its upper end. The two sides of the cylinder 200 are fixedly connected to the two fixed pipes 100 by connecting blocks 107. The first telescopic member and the second telescopic member are respectively installed on the two bottom beams and located inside the fixed pipes 100. The top of the first telescopic member extends into the first connecting frame and is connected to the first connecting frame through a mounting plate 106. The top of the second telescopic member extends into the second connecting frame and is connected to the second connecting frame through a mounting plate 106. The two sides of the cover 300 are respectively provided with a fixing block 105, which is connected to the first connecting frame and the second connecting frame.

[0055] When it is necessary to open the cover 300 for feeding, the first and second telescopic components lift the connecting frame 102 upwards. The rise of the connecting frame 102 can drive the cover 300 to rise and open. After feeding is completed, the first and second telescopic components retract and can drive the connecting frame 102 to descend so that the cover 300 can be reset.

[0056] It is understandable that the first telescopic component and the first connecting frame can form a support on one side, and the second telescopic component and the second connecting frame can form a support on the other side. The support on both sides can improve the stability of the assembly and lifting movement of the cover 300.

[0057] Optionally, the first and second telescopic components are hydraulic devices.
