Description

Technical Field

[0001] This utility model relates to the field of waterproof coating technology, specifically a mixing and proportioning device for waterproof coating production. Background Technology

[0002] Waterproof coatings are functional coatings that prevent the penetration of rainwater, groundwater, industrial and civil water supply and drainage, and corrosive liquids. They are widely used in building roofs, basements, bathrooms, exterior walls, and in water conservancy and transportation engineering projects. Different manufacturers may adjust and optimize the proportions of ingredients according to specific circumstances, but regardless of the adjustments and optimizations, the production of waterproof coatings cannot be separated from the mixing of raw materials, thus requiring the use of mixing and proportioning equipment.

[0003] For example, a mixing device for producing waterproof coatings, as described in application number CN202022415860.5, includes a mixing tank. A support rod is fixedly connected to the bottom of the mixing tank, and a support block is fixedly connected to one end of the support rod. A discharge valve is fixedly connected to the bottom of the mixing tank. A first raw material tank is fixedly connected to the top wall of the mixing tank. A feed pipe is fixedly connected to the outer wall of the first raw material tank, and a first connecting valve is fixedly connected to one end of the first connecting valve. A second connecting pipe is fixedly connected to the outer wall of the mixing tank. This mixing device for producing waterproof coatings achieves convenient proportioning, solving the problem of inconvenient proportioning in general mixing devices. It makes mixing waterproof coating raw materials more convenient, saving a significant amount of time spent on individual proportioning, greatly improving mixing efficiency, and increasing work efficiency.

[0004] Although the aforementioned patent achieves centralized addition of raw materials through structures such as the first raw material box and the second connecting pipe, the proportion control relies on manual operation of the connecting valve to adjust the raw material flow. Manual control makes it difficult to accurately control the amount of different raw materials added, and human error can easily lead to an imbalance in the formula ratio, which in turn causes fluctuations in the performance of the waterproof coating and makes it difficult to meet the production requirements of high-quality coatings. Furthermore, the use of a unidirectional stirring structure results in a limited stirring range, and the edges and corners inside the tank are prone to forming mixing dead zones, leading to uneven dispersion of raw materials and affecting the mixing effect.

[0005] Therefore, we propose a mixing and proportioning device for the production of waterproof coatings to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a mixing and proportioning device for the production of waterproof coatings, so as to solve the problems mentioned in the background art: the existing mixing and proportioning devices are difficult to accurately control the amount of different raw materials added, are prone to imbalance of formula ratio due to human error, and have limited stirring range, resulting in uneven dispersion of raw materials and affecting the mixing effect.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a mixing and proportioning device for waterproof coating production, comprising a proportioning tank, a quantitative dispensing component installed on the proportioning tank, the quantitative dispensing component including a support block fixedly connected to the outer wall of the proportioning tank, a rotating ring rotatably connected to the support block, a leakage hole opened on the rotating ring, multiple support seats fixedly connected to the proportioning tank, a storage hopper fixedly connected to each of the multiple support seats, a discharge pipe connected to the bottom of the storage hopper, multiple inlet pipes connected to the outer wall of the proportioning tank, the leakage hole having the same diameter as the discharge pipe and the inlet pipe respectively, a mixing component installed inside the proportioning tank, and a discharge pipe connected to the bottom of the proportioning tank.

[0008] Preferably, the bottom surface of the rotating ring is provided with a sliding groove, and the rotating ring is slidably connected to the support block through the sliding groove.

[0009] Preferably, a connecting block is fixedly connected to the side wall of the rotating ring, a support column is fixedly connected to the side wall of the proportioning tank, a cylinder is hinged to the end of the support column, a piston rod is fixedly connected to the output end of the cylinder, a connecting rod is fixedly connected to the top of the piston rod, and the connecting rod is fixedly connected to the connecting block.

[0010] Preferably, the rotating ring has multiple leakage holes, the number of leakage holes corresponding to the number of storage hoppers, and the discharge pipe and the feed pipe are connected through the leakage holes.

[0011] Preferably, the mixing assembly includes a motor fixedly connected to the top of the mixing tank, a coupling fixedly connected to the output end of the motor, a crank fixedly sleeved on the outer ring of the coupling, a rotating shaft rotatably connected inside the crank, a gear fixedly sleeved on the outer ring of the rotating shaft, a gear ring fixedly connected inside the mixing tank, the gear ring meshing with the gear, and a stirring shaft fixedly connected to the bottom of the rotating shaft.

[0012] Preferably, the inner wall of the top of the mixing tank is provided with an annular groove, an embedded block is slidably connected in the annular groove, and the rotating shaft is rotatably sleeved with the embedded block.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Through the coordinated operation of the quantitative batching components, the precise proportion of waterproof coating raw materials is achieved. For different raw material proportioning requirements, simply adjust the connection time of the corresponding leakage hole of the rotating ring to ensure that the raw materials enter the proportioning tank in the preset proportion. Compared with manual batching, this structure avoids the problem of human operation error and can adapt to the proportioning requirements of various raw materials (emulsion, filler, additives, etc.). In addition, the transparent design of the storage hopper facilitates real-time monitoring of the raw material balance, further ensuring the continuity and accuracy of the batching process and improving the quality stability of the waterproof coating mixing ratio.

[0015] 2. The motor drives the crank to rotate the shaft, while the meshing of gears and gear rings enables the shaft to rotate on its own axis. This creates a three-dimensional mixing trajectory within the mixing tank. The revolution expands the mixing range, ensuring that the raw materials at both the edge and center of the tank are fully agitated. The rotation generates strong shear force on the raw materials through the high-speed rotation of the mixing shaft, effectively breaking up the agglomeration of the emulsion and solid fillers. This solves the problem of mixing dead zones that exist in traditional unidirectional mixing, further improving mixing efficiency and uniformity, and avoiding performance fluctuations in the waterproof coating caused by uneven mixing.

[0021] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: Please refer to Figure 1 - Figure 3A mixing and proportioning device for waterproof coating production includes a proportioning tank 1, which serves as the core container for mixing and proportioning waterproof coating raw materials. It is made of stainless steel, has good corrosion resistance, and can adapt to the chemical characteristics of various waterproof coating raw materials (such as emulsions, fillers, additives, etc.). The volume of the proportioning tank 1 is designed according to the production scale, and the tank wall has graduations for easy observation of the mixing of internal materials.

[0023] The mixing tank 1 is equipped with a quantitative dispensing component 2, which is a key part for achieving precise proportioning of raw materials. Through the coordinated action of various components, different raw materials are controlled to enter the mixing tank 1 in a set proportion. The quantitative dispensing component 2 includes a support block 21 fixedly connected to the outer wall of the mixing tank 1, which serves to support the rotating ring 22. The rotating ring 22 is rotatably connected to the support block 21, and the rotating ring 22 has a leakage hole 29. Multiple support seats 210 are fixedly connected to the mixing tank 1, and storage hoppers 211 are fixedly connected to each of the multiple support seats 210 for storing various raw materials of waterproof coating. The storage hoppers 211 are made of transparent or semi-transparent plastic or metal material to facilitate observation of the remaining amount of raw materials inside. The bottom of the storage hopper 211 is connected to a discharge pipe 212, and multiple feed pipes 3 are connected to the outer wall of the mixing pipe. The leakage hole 29 is consistent with the diameter of the discharge pipe 212 and the feed pipe 3, respectively, to ensure that the raw materials can flow smoothly and without leakage when passing through.

[0024] The bottom surface of the rotating ring 22 has a sliding groove 23, through which the rotating ring 22 is slidably connected to the support block 21. A connecting block 24 is fixedly connected to the side wall of the rotating ring 22, and a support column 25 is fixedly connected to the side wall of the proportioning tank 1. A cylinder 26 is hinged to the end of the support column 25, and a piston rod 27 is fixedly connected to the output end of the cylinder 26. A connecting rod 28 is fixedly connected to the top of the piston rod 27, and the connecting rod 28 is fixedly connected to the connecting block 24. The connecting block 24 is used to connect the rotating ring 22 and the piston rod 27, transmitting the thrust or pull force of the piston rod 27 to the rotating ring 22, causing the rotating ring 22 to rotate. Multiple drain holes 29 are provided on the rotating ring 22, corresponding to the number of storage hoppers 211. The discharge pipe 212 and the feed pipe 3 are connected through the drain holes 29.

[0025] Specifically, in the initial state, the leakage hole 29 on the rotating ring 22 is not aligned with any discharge pipe 212 and feed pipe 3. At this time, the raw material in the storage hopper 211 is blocked by the ring surface of the rotating ring 22 and cannot flow out from the discharge pipe 212, ensuring that the raw material will not enter the proportioning tank 1 at will.

[0026] When it is necessary to mix ingredients, cylinder 26 is activated. Cylinder 26 pushes connecting rod 28 through piston rod 27. Connecting rod 28 drives connecting block 24 to make rotating ring 22 start to rotate. Under the support of support block 21, rotating ring 22 rotates smoothly along the sliding groove 23 on the bottom surface. According to the raw material ratio and addition sequence required for production, the extension and retraction of piston rod 27 of cylinder 26 is controlled so that rotating ring 22 rotates to a specific angle. At this time, one or more leakage holes 29 on rotating ring 22 just rotate to the corresponding discharge pipe 212 and feed pipe 3, connecting the two.

[0027] Different raw materials in multiple storage hoppers 211 flow out from the discharge pipe 212 under the action of gravity, pass through the leakage hole 29 on the rotating ring 22, and then enter the proportioning tank 1 through the feed pipe 3. Since the aperture of the leakage hole 29 and the rotation time of the rotating ring 22 can be precisely controlled, the flow rate and addition amount of raw materials can be precisely controlled.

[0028] For example, when a certain amount of a raw material needs to be added, the corresponding drain hole 29 on the rotating ring 22 is connected to the discharge pipe 212 of the raw material storage hopper 211 and the inlet pipe 3 of the proportioning tank 1 for a certain period of time. The amount of raw material flowing into the proportioning tank 1 during this period is the set amount. After one raw material is added, the cylinder 26 drives the rotating ring 22 to continue rotating, causing the drain hole 29 to be misaligned with the discharge pipe 212 and the inlet pipe 3, stopping the addition of that raw material. At the same time, the next drain hole 29 is aligned with the corresponding discharge pipe 212 and the inlet pipe 3, and the addition of the next raw material begins. By controlling the connection state of different drain holes 29 on the rotating ring 22 in this way, multiple raw materials can be sequentially introduced into the proportioning tank 1 according to a set ratio.

[0029] Once all raw materials have fallen into the mixing tank 1, the quantitative mixing can be completed. The stirring component in the mixing tank 1 is activated to fully mix the raw materials, ultimately forming a uniform waterproof coating. The entire process is automated by controlling the rotation of the rotating ring 22 through the cylinder 26, which improves the accuracy of the mixing ratio and production efficiency.

[0030] Example 2: This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figure 1 - Figure 2 and Figure 4 The mixing tank 1 is equipped with a mixing component 4. The bottom of the mixing tank 1 is connected to a discharge pipe 5. The discharge pipe 5 is equipped with a valve (such as a ball valve or butterfly valve) to control the discharge of the waterproof coating after mixing. The valve is linked to the control system to realize automatic opening and closing. The valve is existing technology, so it will not be described in detail.

[0031] The mixing component 4 includes a motor 41 fixedly connected to the top of the mixing tank 1. The output end of the motor 41 is fixedly connected to a coupling 42. A crank 43 is fixedly sleeved on the outer ring of the coupling 42. A rotating shaft 44 is rotatably connected inside the crank 43. A gear 47 is fixedly sleeved on the outer ring of the rotating shaft 44. A gear ring 48 is fixed inside the mixing tank 1. The gear ring 48 and the gear 47 mesh with each other. A stirring shaft 49 is fixedly connected to the bottom of the rotating shaft 44. It should be noted that a visual misunderstanding may arise from the attached drawings, namely, that the movement of the stirring shaft 49 may be restricted by the space of the mixing tank 1, thereby affecting its stable rotation. However, in actual operation, the combined revolution and rotation of the stirring shaft 49 is achieved through precise structural design and spatial layout optimization. A reasonable safety gap is left between the length of the stirring shaft 49, the radius of the revolution trajectory, and the inner diameter of the proportioning tank 1. At the same time, the guide support of the embedded block 46 and the annular groove 45 ensures the accuracy of the movement of the rotating shaft 44. Therefore, the stirring shaft 49 will not come into contact with or interfere with the proportioning tank 1 during the revolution and rotation process, and can always maintain a stable motion state.

[0032] An annular groove 45 is provided on the inner wall of the top of the mixing tank 1. An embedded block 46 is slidably connected in the annular groove 45. The rotating shaft 44 is rotatably sleeved with the embedded block 46.

[0033] Specifically, after the quantitative ingredient addition component 2 completes the addition of raw materials, the motor 41 of the mixing component 4 is started. The output end of the motor 41 drives the crank 43 to rotate through the coupling 42. The crank 43 then revolves around the shaft of the motor 41, which in turn drives the rotating shaft 44 connected to it to revolve synchronously. At this time, since the gear 47 on the rotating shaft 44 meshes with the gear ring 48 fixed in the proportioning tank 1, the gear 47 rolls along the gear ring 48 and rotates on its own axis during the revolution, thereby driving the rotating shaft 44 and the stirring shaft 49 at the bottom to rotate synchronously.

[0034] During the above process, the inner block 46 at the top of the rotating shaft 44 slides along the annular groove 45 on the inner wall of the mixing tank 1, providing guidance and support for the revolution of the rotating shaft 44, and preventing the rotating shaft 44 from shifting due to centrifugal force. Under the combined motion of the stirring shaft 49 revolving around the crank 43 and rotating around its own axis, the stirring blades of its shaft form a three-dimensional stirring of the raw materials in the mixing tank 1. The stirring shaft 49 expands the stirring range through revolution, ensuring that the raw materials in the edge and center areas of the tank can be stirred, and through its own high-speed rotation, it generates shearing, impact and mixing effects on the raw materials, breaking the layering and agglomeration between the raw materials.

[0035] For waterproof coating raw materials with different properties (such as high-viscosity emulsions and solid fillers), the movement speed of the stirring shaft 49 can be changed by adjusting the speed of the motor 41. Low speed is suitable for initial mixing and avoids splashing of raw materials; high speed can achieve uniform dispersion through strong shear force. During the stirring process, the raw materials are continuously convection and diffusion under the action of the stirring blades, eventually forming a homogeneous mixture.

[0036] Once mixing is complete, open the valve on the discharge pipe 5. The mixed waterproof coating will be discharged from the bottom of the mixing tank 1 through the discharge pipe 5 under gravity, and will then proceed to the next process. After closing the valve, the next batch of raw materials can be proportioned and mixed, achieving continuous production.

[0037] Through this composite mixing method, mixing component 4 solves the problem of mixing dead zones that exist in traditional single-direction mixing, improves the mixing uniformity and efficiency of waterproof coating raw materials, and ensures the stability of product quality.

[0038] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
