Description

Technical Field

[0001] This utility model relates to the field of storage tank technology, specifically to an acrylic emulsion anti-precipitation homogenizing storage tank. Background Technology

[0002] As is well known, pigment and filler particles in acrylic emulsions are prone to settling under gravity. During storage, the emulsion may separate due to insufficient viscosity or large particle size. Therefore, acrylic emulsions need to be stored in homogenizing storage tanks.

[0003] For example, the utility model patent with application publication number CN218189192U, application publication date of January 3, 2023, and titled "A Homogenizing Storage Tank", has the following specific structure: a tank body with a storage cavity inside; a support leg at the bottom of the tank body; a top cover on the top of the tank body; a hinge shaft inserted on the left side of the top cover; the hinge shaft being fixed inside the upper end of the left side wall of the tank body; and a stirring structure including a rotating frame with an assembly frame fixed to its side; an assembly bolt inserted inside the assembly frame; the assembly bolt being fixed to the inner side wall of the tank body; a rotating rod inserted in the middle of the rotating frame; a stirring blade fixed to the surface of the rotating rod; a driven cap fixed to the top of the rotating rod; and a locking block on the surface of the driven cap.

[0004] The shortcoming of the existing technology is that the rotating rod inside the tank drives the stirring blades to rotate in order to stir the liquid inside the tank. However, when the stirring blades on the rotating rod rotate vertically, the flow direction is the same. As the liquid inside the tank is continuously stirred by the stirring blades, the top and bottom of the tank are prone to stratification, which in turn makes the liquid at the top and bottom of the storage tank uneven in texture. Utility Model Content

[0005] The purpose of this invention is to provide an anti-precipitation homogenizing storage tank for acrylic emulsions to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an acrylic emulsion anti-precipitation homogenizing storage tank, comprising a tank body and a rotating rod rotatably disposed therein, wherein a first blade and a second blade with opposite directions are coaxially arranged on the rotating rod, and the first blade and the second blade rotate synchronously to drive the liquid at the top and bottom of the tank body to flow towards the middle.

[0007] As a further description of the above technical solution: both the first blade and the second blade are axially slidably arranged on the rotating rod.

[0008] As a further description of the above technical solution: an arched ring portion located between the first blade and the second blade is fixedly provided on the rotating rod.

[0009] As a further description of the above technical solution: a plurality of sliding plates are fixedly arranged in a circular array on the rotating rod, and a plurality of sliding grooves that slide and cooperate with the sliding plates are opened on the first blade and the second blade.

[0010] As a further description of the above technical solution: the rotating rod is fixedly provided with limiting plates located at both ends of the sliding plate, and the first blade and the second blade are provided with limiting grooves.

[0011] As a further description of the above technical solution: it also includes an elastic ring plate arranged coaxially with the rotating rod, the first blade is located vertically above the second blade, the first end of the elastic ring plate is fixedly connected to the second blade, and the second end of the elastic ring plate is fixedly connected to the limiting plate.

[0013] As a further description of the above technical solution: the first blade is made of stainless steel.

[0014] As a further description of the above technical solution: the second blade is made of stainless steel.

[0015] As a further description of the above technical solution: the rotating rod is provided with a corrosion-resistant coating.

[0016] In the above technical solution, the present invention provides an acrylic emulsion anti-sedimentation homogenizing storage tank, which utilizes the synchronous rotation of the first and second blades to form a vertical circulating flow within the tank, thereby achieving stirring and homogenization between the top, middle and bottom layers of the tank, preventing the acrylic emulsion in the tank from vertically stratifying due to gravity settling, and improving the storage stability of the acrylic emulsion.

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] Please see Figure 1-5 This utility model provides a technical solution: an acrylic emulsion anti-precipitation homogenizing storage tank, including a tank body 1 and a rotating rod 2 rotatably disposed therein. A first blade 3 and a second blade 4 with opposite directions are coaxially arranged on the rotating rod 2, and the first blade 3 and the second blade 4 rotate synchronously to drive the liquid at the top and bottom of the tank body 1 to flow towards the middle.

[0022] Preferred, such as Figure 2 As shown, the rotating rod 2 is rotatably mounted inside the tank body 1 to drive the first blade 3 and the second blade 4 to rotate synchronously. A drive motor 9 is also mounted on the tank body 1 to drive the rotating rod 2 to rotate. The blades of the first blade 3 and the second blade 4 are in opposite directions, as shown... Figure 5 As shown, when acrylic emulsion is stored in tank 1, the rotating rod 2 can drive the first blade 3 and the second blade 4 to rotate synchronously. The first blade 3 rotates to drive the acrylic emulsion at the top layer of tank 1 to flow to the middle layer of tank 1, and the second blade 4 rotates to drive the acrylic emulsion at the bottom layer of tank 1 to flow to the middle layer of tank 1. The acrylic emulsion in the middle layer is driven by the rotation of the first blade 3 and the second blade 4 to flow closer to the inside of tank 1. Thus, the synchronous rotation of the first blade 3 and the second blade 4 forms a vertical circulation flow in tank 1, realizing the stirring and homogenization between the top, middle and bottom layers in tank 1, avoiding the vertical stratification of acrylic emulsion in tank 1 due to gravity settling, and improving the storage stability of acrylic emulsion.

[0023] The drive motor 9 and its control program are common technical knowledge to those skilled in the art, and will not be described in detail here.

[0024] In the above technical solution, the first blade 3 and the second blade 4 are rotated synchronously to form a vertical circulating flow inside the tank 1, thereby achieving stirring and homogenization between the top, middle and bottom layers inside the tank 1. This avoids the acrylic emulsion inside the tank 1 from vertically stratifying due to gravity settling, thus improving the storage stability of the acrylic emulsion.

[0025] In another embodiment of the present invention, the first blade 3 and the second blade 4 are both axially slidably arranged on the rotating rod 2.

[0026] Preferred, such as Figure 2 As shown, the first blade 3 and the second blade 4 are both axially slidably arranged on the rotating rod 2. When the acrylic emulsion level in the tank 1 is higher than the first blade 3, the first blade 3 and the second blade 4 are both immersed in the acrylic emulsion. At this time, the rotating rod 2 drives the first blade 3 and the second blade 4 to stir the acrylic emulsion. The first blade 3 and the second blade 4 are axially slid away from each other due to the reaction force of stirring, so that the first blade 3 moves closer to the top of the tank 1 and the second blade 4 moves closer to the bottom of the tank 1, thereby improving the uniformity of stirring of the acrylic emulsion in the tank 1 by the first blade 3 and the second blade 4.

[0027] If the acrylic emulsion level in tank 1 is higher than the lowest active position of the first blade 3 but lower than the highest active position of the first blade 3, the rotating rod 2 drives the first blade 3 and the second blade 4 to stir the acrylic emulsion. The second blade 4 is still subjected to the reaction force and moves to a side closer to the bottom of tank 1, but the first blade 3 is subjected to the reaction force of the liquid and moves to the top of the acrylic emulsion, so that the first blade 3 always remains at the top of the acrylic emulsion level for rotation and stirring. This allows the first blade 3 to be used to alleviate the upward splashing of the upper layer of acrylic emulsion due to the stirring impact, thereby improving the storage stability in tank 1.

[0028] In another embodiment of the present invention, an arched ring portion 23 located between the first blade 3 and the second blade 4 is fixedly provided on the rotating rod 2.

[0029] Preferred, such as Figure 2 As shown, the arched ring 23 and the rotating rod 2 are integrally formed, and the arched ring 23 is located between the first blade 3 and the second blade 4, as shown. Figure 5As shown, when the rotating rod 2 drives the first blade 3 and the second blade 4 to rotate synchronously, the first blade 3 rotates to drive the acrylic emulsion at the top layer of the tank 1 to flow to the middle layer of the tank 1. The top acrylic emulsion, driven by the first blade 3, flows along the surface of the arched ring 23 to change direction towards the inner wall of the middle layer of the tank 1. The second blade 4 rotates to drive the acrylic emulsion at the bottom layer of the tank 1 to flow to the middle layer of the tank 1. The bottom acrylic emulsion, driven by the second blade 4, flows along the surface of the arched ring 23 to change direction towards the inner wall of the middle layer of the tank 1. This increases the flow speed of the acrylic emulsion in the middle layer of the tank 1 towards the inner wall of the tank 1, thereby improving the stirring and homogenization effect of the acrylic emulsion in the tank 1.

[0030] In another embodiment of this utility model, a plurality of sliding plates 21 are fixedly arranged in a circular array on the rotating rod 2, and a plurality of sliding grooves 81 that slide in cooperation with the sliding plates 21 are provided on the first blade 3 and the second blade 4.

[0031] Preferred, such as Figure 3 As shown, the sliding plate 21 and the rotating rod 2 are integrally formed, and the first blade 3 and the second blade 4 are axially slidably installed on the rotating rod 2 through the sliding groove 81 and the sliding plate 21, thereby improving the installation stability of the first blade 3 and the second blade 4 on the rotating rod 2. The sliding plate 21 can also serve as a circumferential flow driving plate for the middle layer of acrylic emulsion in the tank 1, thereby improving the circumferential stirring effect of the acrylic emulsion in the tank 1 in the horizontal direction.

[0032] In another embodiment of the present invention, a limiting plate portion 22 located at both ends of the sliding plate 21 is fixedly provided on the rotating rod 2, and a limiting groove 82 is provided on the first blade 3 and the second blade 4.

[0033] Preferred, such as Figure 4 As shown, the limiting plate 22 and the rotating rod 2 are integrally formed, and the limiting plate 22 and the limiting groove 82 are in contact fit to limit the maximum axial sliding stroke of the first blade 3 and the second blade 4, thereby further improving the installation stability of the first blade 3 and the second blade 4 on the rotating rod 2.

[0034] In another embodiment of the present invention, an elastic ring plate 5 is further provided, which is coaxially arranged with the rotating rod 2. The first blade 3 is located vertically above the second blade 4. The first end of the elastic ring plate 5 is fixedly connected to the second blade 4, and the second end of the elastic ring plate 5 is fixedly connected to the limiting plate 22.

[0035] Preferred, such as Figure 3As shown, the upper end of the elastic ring plate 5 is the first end, and the lower end of the elastic ring plate 5 is the second end. The elastic ring plate 5 is fixed to the second blade 4 and the limiting plate 22 to reset the second blade 4, so that in the default state, both the first blade 3 and the second blade 4 are located at the end of their sliding stroke near the middle of the tank 1. When the amount of acrylic emulsion stored in tank 1 is small, the liquid level of the acrylic emulsion is lower than the lowest active position of the first blade 3, but the second blade 4 is still submerged in the acrylic emulsion. At this time, when the rotating rod 2 drives the first blade 3 and the second blade 4 to rotate synchronously, the first blade 3 does not perform stirring operation, and the second blade 4 is still subjected to the reaction force of stirring and moves to a side closer to the bottom of tank 1. The second blade 4 will move and compress the elastic ring plate 5 to deform, so that the middle part of the elastic ring plate 5 is deformed and extended outward on the side opposite to the axis of the rotating rod 2. At this time, the elastic ring plate 5 is used to block part of the blades on the second blade 4, thereby reducing the driving flow of the second blade 4 and preventing the small amount of acrylic emulsion in tank 1 from being excessively stirred by the second blade 4, which would cause the emulsion to break down, thus improving the protection of the acrylic emulsion.

[0036] In another embodiment of this utility model, the rotating rod 2 is made of stainless steel.

[0037] Preferably, the rotating rod 2 is made of stainless steel to improve its corrosion resistance and compressive strength, thereby increasing the service life of the rotating rod 2.

[0038] In another embodiment of this utility model, the first blade 3 is made of stainless steel.

[0039] Preferably, the first blade 3 is made of stainless steel to improve its corrosion resistance and compressive strength, thereby increasing the service life of the first blade 3.

[0040] In another embodiment of this utility model, the second blade 4 is made of stainless steel.

[0041] Preferably, the second blade 4 is made of stainless steel to improve its corrosion resistance and compressive strength, thereby increasing the service life of the second blade 4.

[0042] In another embodiment of this utility model, the rotating rod 2 is provided with a corrosion-resistant coating.

[0043] Working principle: When the acrylic emulsion level in tank 1 is higher than the first blade 3, both the first blade 3 and the second blade 4 are immersed in the acrylic emulsion. At this time, the rotating rod 2 drives the first blade 3 and the second blade 4 to stir the acrylic emulsion. The first blade 3 and the second blade 4 are axially slid away from each other due to the reaction force of stirring, so that the first blade 3 moves closer to the top of tank 1 and the second blade 4 moves closer to the bottom of tank 1, thereby improving the uniformity of stirring of the acrylic emulsion in tank 1 by the first blade 3 and the second blade 4. When the acrylic emulsion level in tank 1 is higher than the lowest active position of the first blade 3 but lower than the highest active position of the first blade 3, the rotating rod 2 drives the first blade 3 and the second blade 4 to stir the acrylic emulsion. The second blade 4 is still subjected to the reaction force and moves to a side closer to the bottom of tank 1, but the first blade 3 is subjected to the liquid reaction force and moves to the top of the acrylic emulsion, so that the first blade 3 always remains at the top of the acrylic emulsion level for rotation and stirring. When the amount of acrylic emulsion stored in tank 1 is small, the liquid level of the acrylic emulsion is lower than the lowest active position of the first blade 3, but the second blade 4 is still submerged in the acrylic emulsion. At this time, when the rotating rod 2 drives the first blade 3 and the second blade 4 to rotate synchronously, the first blade 3 does not perform stirring operation, and the second blade 4 is still subjected to the reaction force of stirring and moves to the side closer to the bottom of tank 1. The second blade 4 will move and compress the elastic ring plate 5 to deform, so that the middle part of the elastic ring plate 5 is deformed and extended outward on the side opposite to the axis of the rotating rod 2. At this time, the elastic ring plate 5 is used to block part of the blades on the second blade 4, thereby reducing the driving flow of the second blade 4.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
