Description

Technical Field

[0001] The utility model belongs to the technical field of waterproof composite materials, in particular to a mixing device for preparing waterproof composite materials. Background Art

[0002] Composite waterproof material is a two-component waterproof coating composed of organic liquid and various additives and inorganic powder. It is a waterproof material that has the advantages of high elasticity of organic materials and good durability of inorganic materials. After coating, it forms a high-strength and tough waterproof coating film, and can be prepared with colored coating according to project needs. It can be directly constructed on wet or dry masonry, mortar, concrete, metal, wood, and various insulation layers. It can be used for various new and old buildings and structures. In the preparation process of composite waterproof materials, mixing equipment is needed to mix and stir various raw materials. The working principle of the mixer is to use the high-speed friction between the rotor and the stator to clamp, compress, shear, stir and other forces on the material to achieve the effect of mixing, mixing and plasticizing. However, it still has the following disadvantages in actual use:

[0003] 1. The utility model with publication number CN214725462U discloses a paint raw material mixing equipment, which includes a tank body and a working platform, the tank body is rotatably connected to the upper end of the working platform, a supporting mechanism is arranged at the lower side of the working platform, a driving motor is arranged at the lower side of the tank body, an output end of the driving motor is fixedly connected to a first rotating rod, the upper end of the first rotating rod moves from bottom to top and passes through the lower end of the working platform and the tank body in sequence, and the output end of the first rotating rod is rotatably connected to the upper inner wall of the tank body, a plurality of uniformly distributed stirring rods are fixedly connected to the surface of the first rotating rod, a first mounting hole is drilled at the upper end of the working platform, a bearing is fixedly connected in the first mounting hole, and a second rotating rod is fixedly connected in the bearing. When the mixing equipment mixes a variety of raw materials and auxiliary materials, the multiple raw materials and auxiliary materials are often not poured into the equipment at the same time for processing, but are poured into the equipment in steps for mixing and stirring. However, in actual processing, a small amount of newly added multiple auxiliary materials is difficult to be quickly mixed with a large amount of high-speed stirred raw materials, which reduces the processing efficiency;

[0004] 2. When mixing raw materials, some raw materials need to be processed at a certain temperature, and when adding auxiliary materials again, the raw materials need to be cooled down to avoid adverse reactions caused by large temperature differences between the two raw materials. However, mixing equipment usually finds it difficult to cool down the raw materials quickly, and the raw materials are often stirred at high speed during cooling. Frictional heat is generated during stirring, which reduces the cooling rate. Utility Model Content

[0008] The feeding motor can drive the second screw conveying assembly and the third screw conveying assembly to rotate, so that the raw materials can move up and down in the upper mixing box, the temperature control assembly and the lower mixing box, and a large amount of raw materials can be extruded and mixed through a plurality of relatively thin feeding pipes, and the raw materials can be heated or cooled by passing the raw materials through the feeding pipes, and there is no need to use a stirring structure, thereby avoiding the temperature of the raw materials being affected by the frictional heat generated during stirring during the temperature control process, and a plurality of relatively thin feeding pipes can greatly increase the heat conduction area and improve the temperature control efficiency. The flow of air driven by the heat dissipation fan can cool the raw materials passing through the feeding pipes, thereby improving the temperature of the raw materials. The equipment has a high degree of automation. When the raw materials pass through the bottom of the upper mixing box, the newly added auxiliary materials can be gradually added into the upper mixing box through the feeding pipe, so that the raw materials and auxiliary materials are mixed, avoiding directly pouring the auxiliary materials into the upper mixing box, so that the raw materials and auxiliary materials can be quickly and evenly mixed.

When the telescopic box moves to the lowest point, it is judged that the raw materials have been mixed once. When the telescopic box is reset again, it is judged that the raw materials have been mixed again, which is convenient for the staff to judge the adding time of multiple auxiliary materials and further ensure the mixing efficiency.

[0010] The feed motor drives the first screw conveying assembly to rotate, so that the raw materials in the feed hopper can be conveyed to the upper mixing box, thereby ensuring the conveying speed of the raw materials and improving the automation degree of the equipment.

[0011] Furthermore, a second rotating rod is clamped at the bottom of the feeding motor, the second screw conveying assembly and the third screw conveying assembly are clamped and fixed to the outer circumferential surface of the second rotating rod, the second rotating rod is inserted through the top of the upper mixing box, the second screw conveying assembly is attached to the inner wall of the upper mixing box, and the third screw conveying assembly is attached to the inner wall of the lower mixing box;

[0013] Furthermore, a first one-way ventilation component is inserted through one end of the heat dissipation fan, and the heat dissipation fan is located between the first one-way ventilation component and the temperature control component. A second one-way ventilation component is inserted through one side of the temperature control component, and the second one-way ventilation component is located on the other side of the temperature control component relative to the heat dissipation fan.

[0014] When the raw materials pass through the feed pipe, when the temperature of the raw materials needs to be regulated, the heating plate can heat the feed pipe to further heat the raw materials passing through the feed pipe, and the heat dissipation fan can drive the flow of air to further dissipate the heat of the raw materials in the feed pipe.

[0018] When the raw materials enter the lower mixing box and move downward, the telescopic box can be squeezed to move it downward. When the telescopic box moves to the lowest point, it is determined that all the raw materials have been mixed once. When the telescopic box is reset again, it is determined that the raw materials have been mixed again. This is convenient for the staff to determine the addition time of various auxiliary materials and further ensure the mixing efficiency.

[0019] The utility model has the following beneficial effects:

[0020] 1. The utility model solves the problem that when a mixing device mixes a variety of raw materials and auxiliary materials, the multiple raw materials and auxiliary materials are often not poured into the device at the same time for processing, but are poured into the device step by step for mixing and stirring. However, in actual processing, a small amount of multiple auxiliary materials newly added are difficult to quickly mix with a large amount of raw materials stirred at high speed, which reduces the processing efficiency. When the raw materials are in the mixing device, the feeding motor drives the second screw conveying assembly and the third screw conveying assembly to move up and down, so that the raw materials move up and down in the mixing device, and at the same time, the auxiliary materials are poured into the feeding hopper, and the auxiliary materials are uniformly conveyed through the feeding pipe, so that the auxiliary materials are gradually added to the upper mixing box, so that the raw materials and auxiliary materials are mixed, avoiding directly pouring the auxiliary materials into the upper mixing box, so that the raw materials and auxiliary materials can be quickly and evenly mixed.

[0021] 2. The utility model solves the problem that when mixing raw materials, some raw materials need to be processed at a certain temperature, and when auxiliary materials are added again, the raw materials need to be cooled down to avoid adverse reactions caused by large temperature differences between the two raw materials. However, mixing equipment usually finds it difficult to quickly cool down the raw materials, and the raw materials are often stirred at a high speed during cooling, which generates frictional heat during stirring and reduces the cooling rate. The second screw conveying assembly and the third screw conveying assembly are driven up and down by the feeding motor to move the raw materials up and down in the mixing equipment, and further all the raw materials are passed through the feed pipe for multiple times, and the feed pipe is heated as needed, or the heat is dissipated by the heat dissipation fan to further adjust the temperature of the raw materials. There is no need to use a stirring structure, which avoids the raw material temperature being affected by frictional heat generated during stirring during the temperature control process, and multiple thinner feed pipes can greatly increase the heat conduction area and improve the temperature control efficiency.
