Description

Technical Field

[0001] This utility model relates to the field of mold release agent technology, and in particular to a mixing and preparation apparatus for a mold release agent. Background Technology

[0002] In the fields of chemical engineering and building materials (especially precast concrete components), the preparation of release agents typically involves the thorough and uniform mixing of various raw materials (such as base oil, emulsifier, water, and additives). Traditional mixing devices often employ fixed stirring blades, which create a relatively fixed flow pattern during the mixing process. This leads to uneven material mixing and unstable emulsification, which in turn affects the final performance of the release agent (such as poor demolding or damage to the mold or concrete surface). Therefore, a mixing and preparation device for release agents is proposed. Utility Model Content

[0003] Therefore, it is necessary to provide a mixing and preparation device for a release agent to address the aforementioned technical problems. This unit, through the synergistic action of the contacting and reciprocating components, can drive a dynamic flow-around unit to reciprocate and oscillate while the stirring shaft rotates. This allows the turbulence-causing blades fixed on both sides of the support arm to not only revolve with the shaft but also oscillate within a certain angle, thereby breaking the fixed flow field pattern within the mixing tank, generating complex and variable turbulence and shear forces, effectively eliminating mixing dead zones, and greatly improving the mixing uniformity and efficiency of the materials.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A mixing and preparation apparatus for a release agent includes a mixing tank, a top cover installed on the top of the mixing tank, a stirring shaft movably connected to the bottom of the mixing tank via a sealing shaft, a movable cylinder sleeved on the surface of the stirring shaft, and a dynamic flow-around unit connected to the movable cylinder on the surface of the stirring shaft.

[0006] One end of the stirring shaft extends outside the top cover and is connected to an abutment. Below the abutment is a reciprocating component that is assembled with the movable cylinder. The dynamic flow unit can be made to reciprocate under the action of the abutment and the reciprocating component.

[0007] The dynamic flow-around unit includes a connecting ring movably sleeved on the surface of the movable cylinder via a bearing, a first connecting seat fixed to the outside of the connecting ring, and a transmission arm hinged inside the first connecting seat. The end of the transmission arm is connected to a second connecting seat, and a support arm is fixed to the surface of the second connecting seat.

[0008] The inner end of the support arm is movably connected to the surface of the stirring shaft, and turbulence blades are fixed on both sides of the support arm.

[0009] Furthermore, a servo motor is installed at the bottom of the mixing tank, and the output end of the servo motor is coaxially fixed with the bottom end of the stirring shaft.

[0010] Furthermore, the abutment includes a connecting disc sleeved on the top of the stirring shaft, a clamping ring for pressing the connecting disc is threaded onto the surface of the stirring shaft, and an upper abutment block is connected to the edge of the connecting disc.

[0011] Furthermore, the reciprocating component includes a sliding ring slidably disposed within a protrusion on the top cover and a spring connected to the bottom of the sliding ring and connected to the bottom wall of the top cover, wherein the top of the sliding ring has an insertion groove.

[0012] Furthermore, a transmission rod is inserted into the insertion slot, and multiple transmission rods extend to the outside of the protrusion and are connected to a tripod. A lower abutment block is fixed to the top of the tripod.

[0013] Furthermore, the bottom of the tripod is provided with a connecting groove for engaging with the movable cylinder, and the surface of the tripod is also threaded with a fixing bolt that locks with the movable cylinder.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The mold release agent mixing and preparation device provided by this utility model, through the synergistic action of the abutting and reciprocating components, can drive the dynamic flow-around unit to reciprocate and oscillate while the stirring shaft rotates. This allows the turbulence-causing blades fixed on both sides of the support arm to not only revolve with the shaft but also oscillate reciprocally within a certain angle, thereby breaking the fixed flow field pattern in the mixing tank, generating complex and variable turbulence and shear force, effectively eliminating mixing dead zones, and greatly improving the mixing uniformity and efficiency of the materials.

[0016] The contact component is fixed to the top of the stirring shaft via a connecting plate and a clamping ring, facilitating adjustment and disassembly. The reciprocating component is locked to the movable cylinder with fixing bolts, and the connecting groove design also facilitates quick engagement and positioning. These modular designs make the assembly, disassembly, and maintenance of the core moving parts more convenient. Attached Figure Description

[0031] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0032] Example 1

[0033] Please refer to Figures 1-5 As shown, a mixing and preparation device for a release agent includes a mixing tank 1, a top cover 2 installed on the top of the mixing tank 1, a stirring shaft 3 movably connected to the bottom of the mixing tank 1 via a sealing shaft, a movable cylinder 4 sleeved on the surface of the stirring shaft 3, and a dynamic flow unit 5 connected to the movable cylinder 4 on the surface of the stirring shaft 3.

[0034] One end of the stirring shaft 3 extends outside the top cover 2 and is connected to an abutment 6. Below the abutment 6 is a reciprocating component 7 that is assembled with the movable cylinder 4. The dynamic flow unit 5 can reciprocate under the action of the abutment 6 and the reciprocating component 7.

[0035] Because the mold release agent mixing and preparation device of this invention has the above structure, through the synergistic action of the contacting member 6 and the reciprocating member 7, it can drive the dynamic flow-around unit 5 to reciprocate and oscillate while the stirring shaft 3 rotates. This allows the turbulence-causing blades fixed on both sides of the support arm to not only revolve with the shaft but also oscillate and oscillate within a certain angle, thereby breaking the fixed flow field pattern in the mixing tank 1, generating complex and variable turbulence and shear force, effectively eliminating mixing dead zones, and greatly improving the mixing uniformity and efficiency of the mold release agent material.

[0036] Example 2

[0037] The apparatus for preparing the release agent provided in Example 1 has been further optimized, specifically, as follows: Figure 3 As shown, the dynamic flow-around unit 5 includes a connecting ring 55 movably sleeved on the surface of the movable cylinder 4 via a bearing, a first connecting seat 51 fixed to the outside of the connecting ring 55, and a transmission arm 52 hinged inside the first connecting seat 51. The end of the transmission arm 52 is connected to a second connecting seat 53, and a support arm 54 is fixed to the surface of the second connecting seat 53.

[0038] The inner end of the support arm 54 is movably connected to the surface of the stirring shaft 3, and turbulence blades 56 are fixed on both sides of the support arm 54.

[0039] Because the mold release agent mixing and preparation device of this utility model has the above structure, the connecting ring 55 is movably sleeved on the movable cylinder 4 through the bearing, so that the up-and-down reciprocating motion of the movable cylinder 4 can be smoothly converted into the up-and-down motion of the connecting ring 55. When the movable cylinder 4 drives the connecting ring 55 to move up and down, the vertical linear motion is cleverly converted into the reciprocating swing of the support arm 54 and the turbulence blades 56 on it around the axis of the stirring shaft 3 through the linkage mechanism composed of the first connecting seat 51, the transmission arm 52 and the second connecting seat 53. The inner end of the support arm 54 is movably connected to the stirring shaft 3, ensuring the stable fulcrum of the swing motion. The turbulence blades 56 installed on both sides of the support arm 54 thus obtain a composite motion trajectory of "revolution + swing", which can apply multi-directional and changing shear force and disturbance to the fluid, thereby breaking the fixed flow field mode in the mixing tank, generating complex and variable turbulence and shear force, effectively eliminating mixing dead angles, and greatly improving the mixing uniformity and efficiency of the material.

[0040] Example 3

[0041] The apparatus for preparing the release agent provided in Example 1 or 2 has been further optimized, such as... Figure 2 As shown, a servo motor 8 is installed at the bottom of the mixing tank 1, and the output end of the servo motor 8 is coaxially fixed with the bottom end of the stirring shaft 3.

[0042] Because the mold release agent mixing and preparation device of this utility model has the above structure, the servo motor 8 can be started to directly drive the stirring shaft 3 to rotate, thereby realizing the effective stirring of the mold release agent inside the mixing tube 1.

[0043] Example 4

[0044] The apparatus for preparing the release agent provided in Example 3 has been further optimized, such as... Figure 5 As shown, the abutment 6 includes a connecting disc 61 sleeved on the top of the stirring shaft 3, a clamping ring 62 for pressing the connecting disc 61 is threadedly connected to the surface of the stirring shaft 3, and an upper abutment block 63 is connected to the edge of the connecting disc 61.

[0045] Because the mold release agent mixing and preparation device of this utility model has the above structure, the connecting plate 61 is sleeved on the top of the stirring shaft 3 and is pressed and fixed by the threaded clamping ring 62, which makes the structure easy to disassemble and maintain. When it is necessary to replace or adjust the contact parts, the operation is simple.

[0046] Example 5

[0047] The apparatus for preparing the release agent provided in Example 4 has been further optimized, such as... Figure 5 As shown, the reciprocating component 7 includes a sliding ring 71 slidably disposed in the protrusion 21 on the top cover 2 and a spring 72 connected to the bottom of the sliding ring 71 and connected to the bottom wall of the top cover 2. The top of the sliding ring 71 has an insertion groove 73.

[0048] A transmission rod 74 is inserted into the insertion slot 73. Multiple transmission rods 74 extend out of the outer side of the protrusion 21 and are connected to a tripod 75. A lower abutment block 76 is fixed to the top of the tripod 75.

[0049] The bottom of the tripod 75 is provided with a connecting groove 77 for engaging with the movable cylinder 4, and the surface of the tripod 75 is also threaded with a fixing bolt 78 that is locked to the movable cylinder 4.

[0050] Because the mold release agent mixing and preparation device of this utility model has the above structure, the sliding ring 71 slides in the protrusion 21 of the top cover 2, and the spring 72 provides a continuous upward restoring force. The transmission rod 74 is inserted into the insertion slot 73 and connected to the tripod 75, transmitting the vertical linear motion of the sliding ring 71 to the tripod 75. The lower contact block 76 at the top of the tripod 75 is used to interact with the rotating upper contact block 63. Most importantly, the connecting slot 77 at the bottom of the tripod 75 engages with the movable cylinder 4 and is locked by the fixing bolt 78, which ensures the synchronous movement of the movable cylinder 4, the tripod 75, and the entire reciprocating component 7. The entire reciprocating component is a modular assembly, which is very convenient to install, disassemble, and maintain. The elasticity of the spring 72 ensures automatic reset after each contact, preparing for the next contact swing, making the swing action continuous and stable.

[0051] The specific application steps of the mold release agent mixing and preparation device are as follows: The servo motor 8 drives the stirring shaft 3 to rotate at high speed, which is the main power source for mixing. At the same time, the contact member 6 fixed at the top of the stirring shaft 3 also rotates. The upper contact block 63 on it will periodically contact and separate from the lower contact block 76 fixed on the reciprocating member 7 on the top cover 2.

[0052] When the two contact, the upper contact block 63 pushes the lower contact block 76 and the triangular bracket 75 and the movable cylinder 4 below it to move downwards against the resistance of the spring 72. When they separate, the restoring force of the spring 72 pushes the entire reciprocating part 7 to return to its original position. This up-and-down reciprocating motion is transmitted to the connecting ring 55 connected to it through the movable cylinder 4, which in turn drives the angle change of the transmission arm 52 of the dynamic flow unit 5, causing the angle of the turbulence blade 56 to also undergo periodic deformation. This creates a complex, three-dimensional dynamic mixing flow field in the tank, significantly breaking the fixed flow field pattern, effectively eliminating mixing dead zones, and greatly improving the mixing efficiency and effect of materials, especially fluids such as release agents that require high uniformity mixing.

[0053] The rotating clamping ring 62 can disassemble the connecting plate 61, and the fixing bolt 78 can be removed to disassemble the tripod 75. Then the bolts at the upper edge of the top cover 2 can be removed to disassemble the top cover 2, so that the inside of the mixing pipe 1 can be inspected or cleaned.
