Description

Technical Field

[0001] This utility model relates to the field of material mixing technology, and in particular to mixing tanks. Background Technology

[0002] Agitated tanks, commonly used in the chemical industry, primarily function to thoroughly mix and react materials within the tank through rotational motion, meeting the stringent requirements for material uniformity in various processes. During the mixing process, baffles are typically installed inside the tank to optimize mixing effects, eliminate vortices, and improve energy utilization. The presence of baffles effectively alters the flow state of the fluid within the tank, promoting more complex turbulence, thereby enhancing the interaction between materials and improving mixing efficiency and quality.

[0003] In existing technology, baffles are fixedly installed on the inner wall of the mixing tank. The baffles are flat or plate-like structures with a certain curvature. The baffles are usually made of metal and are firmly fixed to the designated positions in the mixing tank by welding, bolting, or other methods. The number, size, and layout of the baffles are designed according to the size and shape of the mixing tank and the requirements of the mixing process. They are generally distributed symmetrically or evenly within the mixing tank to ensure effective alteration of the fluid flow direction and elimination of vortex phenomena.

[0004] In actual operation, the mixing tank handles a wide variety of materials, including some that are sticky, have large particles, or are fibrous. These materials easily adhere to the baffle surface during mixing. Cleaning personnel can only use limited methods, such as long-handled brushes and high-pressure water guns, to perform simple cleaning from inside the mixing tank, resulting in poor cleaning effectiveness and leaving a large amount of material residue on the baffle surface. Over time, this not only affects the normal operation of the mixing tank but may also corrode the baffle material, further shortening the equipment's lifespan and increasing the company's maintenance and production costs. Utility Model Content

[0005] The purpose of this invention is to provide a mixing tank that solves the problem that in the prior art, the baffles inside the mixing tank are difficult to clean effectively during long-term use, resulting in a lot of material residue on the surface of the baffles. This not only affects the normal operation of the mixing tank, but also shortens the service life of the equipment and increases the maintenance and production costs of enterprises.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] This utility model embodiment provides a stirring tank, which includes:

[0008] The main body has a stirring chamber inside, and multiple baffles are movably connected to the wall of the stirring chamber. The multiple baffles are distributed circumferentially around the main body, and each baffle is provided with a support component. The support component is movably connected to the main body and is used to limit the range of motion of the baffle.

[0009] Optionally, the support component includes:

[0010] A support rod, one end of which is rotatably connected to the wall of the stirring chamber;

[0011] The connecting block is slidably connected to the baffle and rotatably connected to the other end of the support rod.

[0012] Optionally, the side of the baffle is provided with a groove, the connecting block is slidably connected in the groove, and the side of the connecting block has a pushing slope to push the material out of the groove.

[0013] Optionally, the side of the chute is provided with a discharge ramp that is inclined toward the connecting block.

[0014] Optionally, the groove has a guide rod, which passes through the connecting block and is slidably connected to the connecting block.

[0015] Optionally, the side of the baffle is provided with multiple material holes.

[0016] Optionally, multiple support components are distributed circumferentially around the baffle.

[0017] Optionally, the cavity wall of the stirring chamber is provided with an installation groove corresponding to the baffle, and a rotating shaft is provided in the installation groove. One side of the baffle extends into the installation groove and is rotatably connected to the rotating shaft.

[0018] Optionally, the mounting groove is provided with a plurality of elastic elements, which are fixedly connected to one side of the baffle.

[0019] Optionally, flexible sealing strips are provided on both sides of the baffle, and the flexible sealing strips are fixedly connected to the cavity wall of the stirring chamber to seal the mounting groove.

[0020] The beneficial effects of this utility model are:

[0021] During mixing, the material's movement within the main body is aided by the baffles, allowing for smooth tumbling. The baffles, constrained by the supporting components, can move within a certain range during mixing, causing adhering material to fall off automatically, thus reducing material residue. After mixing, the baffles can be cleaned. During cleaning, the baffles can be moved to change their position or orientation, enabling efficient cleaning with appropriate tools. Therefore, this mixing tank, by utilizing the baffles' movement within a certain range during mixing, reduces material residue on the baffles. Simultaneously, the baffles' position and orientation can be flexibly adjusted during cleaning, allowing cleaning tools to efficiently clean the baffle surface. This effectively improves cleaning efficiency, reduces material residue on the baffle surface, and ensures minimal material residue even with long-term use, extending the tank's lifespan and reducing maintenance and production costs for the enterprise.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0029] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not 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 limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0032] This utility model discloses a stirring tank.

[0033] Reference Figures 1 to 4 The mixing tank includes a main body 1. The main body 1 has a mixing chamber 11. Multiple baffles 2 are movably connected to the wall of the mixing chamber 11. The multiple baffles 2 are distributed circumferentially around the main body 1. Each baffle 2 is provided with a support component 3. The support component 3 is movably connected to the main body 1 and is used to limit the range of motion of the baffle 2.

[0034] Specifically, the main body 1 can extend horizontally and be driven to rotate by an external drive device to perform material mixing operations. The main body 1 can also extend vertically, in which case a stirring shaft and stirring paddle can be installed inside the main body 1 to stir the materials. The baffle 2 can be rotatably connected to the cavity wall of the stirring chamber 11 or slidably connected to the cavity wall of the stirring chamber 11. It can move to a certain extent as the main body 1 or the materials are stirred. The support component 3 is set on the side of the baffle 2. It can be rod-shaped or plate-shaped, and the side away from the baffle 2 is movably connected to the main body 1, thereby limiting the range of movement of the baffle 2 so that the baffle 2 can effectively stir and mix the materials.

[0035] During the mixing process, the material within the main body 1 is held in place by the baffle 2, allowing it to tumble smoothly. Under the constraint of the support component 3, the baffle 2 can move to a certain extent during mixing, causing material adhering to it to fall off automatically, thus reducing material residue. After mixing, the baffle 2 can be cleaned. During cleaning, the baffle 2 can be moved appropriately to change its position or orientation, allowing for efficient cleaning with appropriate tools. Therefore, during mixing, the movement of the baffle 2 within a certain range reduces material residue. Simultaneously, the position and orientation of the baffle 2 can be flexibly adjusted during cleaning, enabling efficient cleaning of its surface. This effectively improves cleaning efficiency, reduces material residue on the baffle 2 surface, and ensures minimal material residue during long-term use, extending the service life of the mixing tank and reducing maintenance and production costs for the enterprise.

[0036] Optionally, the support assembly 3 includes a support rod 31 and a connecting block 32. One end of the support rod 31 is rotatably connected to the wall of the stirring chamber 11; the connecting block 32 is slidably connected to the baffle 2 and rotatably connected to the other end of the support rod 31.

[0037] Specifically, the support rod 31 is a round rod to reduce the possibility of material adhering to its surface. A connection hole is provided on the wall of the mixing chamber 11. One end of the support rod 31 extends into the connection hole and is rotatably connected via a rotating rod or similar structure. A flexible rubber pad can also be placed at the opening of the connection hole. The rubber pad is fixedly connected to the support rod 31 and the wall of the mixing chamber 11 to seal the connection hole and ensure smooth rotation of the support rod 31. One side of the connecting block 32 slides against the baffle 2, which can be achieved through a slide rail or a groove 21, while the other side of the connecting block 32 is rotatably connected to the other end of the support rod 31 via a connecting rod.

[0038] When the baffle 2 moves, the connecting block 32 slides relative to the baffle 2, and the support rod 31 rotates relative to it. When the connecting block 32 slides to its maximum range, the support rod 31 stops rotating. At this time, the baffle 2 reaches its maximum range of movement in one direction. As the main body 1 rotates or the material flips, the baffle 2 can also move in the opposite direction. In this way, during the material flipping process, the baffle 2 will form a reciprocating movement, which can improve the mixing effect of the material on the one hand, and reduce the possibility of material adhering to the baffle 2 on the other hand.

[0039] Optionally, the side of the baffle 2 is provided with a groove 21, and the connecting block 32 is slidably connected in the groove 21. The side of the connecting block 32 has a pushing slope to push the material out of the groove 21.

[0040] Specifically, the extension direction of the chute 21 can be determined along the actual moving direction of the baffle 2. The connecting block 32 is at least partially located within the chute 21 and slides in cooperation with the chute 21 to limit the sliding direction and range of the connecting block 32. The length of the chute 21 can be determined according to the actual moving range of the baffle 2, and this utility model does not impose any limitation. The side of the connecting block 32 is inclined as a pushing slope, so that during the sliding process, it can push out the material remaining in the chute 21, thereby reducing the possibility of material clogging the chute 21.

[0041] Optionally, the side of the chute 21 is provided with a discharge ramp that is inclined toward the connecting block 32.

[0042] Specifically, the side of the chute 21 is inclined so that when the pushing slope pushes the material to move, the discharging slope can play a guiding role to smoothly discharge the material from the chute 21. At the same time, the discharging slope also makes the opening of the chute 21 open, further reducing the possibility of material accumulating in the chute 21.

[0043] Optionally, the slide 21 has a guide rod 22, which passes through the connecting block 32 and is slidably connected to the connecting block 32.

[0044] Specifically, the guide rod 22 extends along the length of the slide groove 21, and a sliding hole is provided on the connecting block 32. The guide rod 22 passes through the sliding hole and slides in cooperation with the sliding hole. A lubricating film can also be provided on the surface of the guide rod 22, which can reduce material adhesion on the one hand and reduce the friction between it and the connecting block 32 on the other hand.

[0045] By setting the guide rod 22, the sliding direction of the connecting block 32 can be further restricted to ensure that the connecting block 32 remains stable during sliding and reduce the possibility of the connecting block 32 deviating during sliding.

[0046] Optionally, the side of the baffle 2 is provided with multiple material holes 23.

[0047] Specifically, multiple feed holes 23 can be distributed at intervals along the circumference of the baffle 2 so that when the material is stirred, some of the material can pass through the feed holes 23 and through the baffle 2, thereby further reducing the possibility of material residue on the baffle 2.

[0048] Optionally, multiple support components 3 are distributed circumferentially around the baffle 2.

[0049] Specifically, multiple support components 3 can be symmetrically distributed on both sides of the baffle 2 to ensure that the baffle 2 as a whole can be smoothly balanced. In this embodiment, four support components 3 are provided. In other embodiments, the number of support components 3 can be designed according to the size of the baffle 2, and this utility model does not limit this.

[0050] Optionally, the cavity wall of the stirring chamber 11 is provided with an installation groove 12 corresponding to the baffle 2. A rotating shaft 13 is provided in the installation groove 12, and one side of the baffle 2 extends into the installation groove 12 and is rotatably connected to the rotating shaft 13.

[0051] Specifically, the cavity wall of the stirring chamber 11 is partially recessed to form a mounting groove 12. A rotating shaft 13 is provided in the mounting groove 12. The rotating shaft 13 extends along the length of the stirring chamber 11. The side wall of the baffle 2 extends into the mounting groove 12, and a connecting groove is provided on this side of the baffle 2. The connecting groove is adapted to the rotating shaft 13 to form a rotatable connection with the rotating shaft 13.

[0052] The baffle 2 is rotatably connected to the mixing chamber 11 via the rotating shaft 13. During the mixing process, the baffle 2 can swing back and forth around the rotating shaft 13 to improve the mixing effect of the material. During cleaning, the baffle 2 can be rotated appropriately so that both sides of the baffle 2 can be effectively cleaned, thereby improving the cleaning effect.

[0053] Optionally, a plurality of elastic elements 4 are provided in the mounting groove 12, and the elastic elements 4 are fixedly connected to one side of the baffle 2.

[0054] Specifically, the elastic element 4 can be a spring, with one end fixedly connected to the bottom wall of the mounting groove 12 and the other end fixedly connected to the side wall of the baffle 2. Multiple elastic elements 4 can be set and symmetrically distributed on both sides of the rotating shaft 13. During the material stirring process, when one side of the baffle 2 is subjected to force and rotates, it will pull the elastic element 4 on one side and squeeze the elastic element 4 on the other side. When it is no longer subjected to force, the elastic elements 4 on both sides can make the baffle 2 reset and shake within a certain range, thereby throwing off the material or cleaning liquid residues from the baffle 2, further improving the cleaning effect of the baffle 2.

[0055] Optionally, flexible sealing strips 5 are provided on both sides of the baffle 2, and the flexible sealing strips 5 are fixedly connected to the cavity wall of the mixing chamber 11 to seal the mounting groove 12.

[0056] Specifically, a flexible seal 5 is fixedly installed on the baffle 2 near the mounting groove 12. The flexible seal 5 can be made of corrosion-resistant rubber material, and its middle part can be folded so that it can be straightened when the baffle 2 deflects. The specific manufacturing material and length of the flexible seal 5 can be designed according to the actual size of the mounting groove 12, and this utility model does not limit it.

[0057] By setting a flexible seal 5, the mounting groove 12 can be sealed to prevent materials from entering the mounting groove 12 and clogging it, thereby ensuring that the baffle 2 can swing back and forth smoothly.

[0058] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
