Description

Technical Field

[0001] This utility model mainly relates to the technical field of iron-based adhesive production equipment, specifically an iron-based adhesive mixing device. Background Technology

[0002] In the production process of iron-based adhesives, various raw materials (such as iron powder, resin, curing agent, diluent, etc.) need to be mixed and stirred in a certain proportion to ensure that the raw materials are evenly dispersed, thereby guaranteeing the stable performance of the final product. Currently, most commonly used mixing devices on the market are ordinary single-shaft mixing structures. During use, only a single stirring rod is used for radial stirring, which cannot cover materials at different heights in the mixing tank. This easily leads to material stratification, causing the denser iron-based particles in the iron-based adhesive to settle to the bottom of the tank, resulting in an uneven mixing problem of "thin upper layer and thick lower layer," which affects product quality. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an iron-based adhesive mixing device, achieved through the following technical solution: A mixing device for iron-based adhesives includes a mixing tank with an open top surface, a plurality of evenly distributed support legs fixedly installed at the bottom of the mixing tank, a feed pipe integrally fixedly installed at the bottom of the mixing tank, a valve provided at the top of the feed pipe, and a mixing assembly provided inside the mixing tank, the mixing assembly being powered by a drive assembly.

[0004] Furthermore, the stirring assembly includes: Mounting frame, the top surface of the mixing tank is fixedly mounted with the mounting frame; A stirring shaft is provided at the center of the top of the mounting bracket and connected to its bearing. The drive assembly is fixedly connected to the stirring shaft, and the lower end of the stirring shaft extends into the mixing tank. The stirring rods are fixedly installed on the outer periphery of the stirring shaft, and the stirring rods are divided into upper and lower groups.

[0005] Furthermore, the drive component is a geared motor, the geared motor is fixedly mounted on the top surface of the mounting bracket, and the output end of the geared motor is fixedly connected to the upper end of the stirring shaft.

[0006] Furthermore, a spiral stirring blade is fixedly installed on a section of the stirring shaft located inside the stirring tank.

[0007] Furthermore, an insulation jacket is fixedly installed on the outside of the mixing tank, and several evenly distributed electric heating elements are fixedly installed inside the insulation jacket.

[0008] Furthermore, the electric heating elements are evenly distributed along the circumference of the outer wall of the mixing tank, and a temperature sensor is fixedly installed at the bottom of the mixing tank.

[0009] Compared with the prior art, the beneficial effects of this utility model are: This device, by setting up two sets of stirring rods, covers the entire height range of the material. Combined with the axial circulation of the spiral stirring blades, it forms a three-dimensional stirring flow field, which can break the material stratification phenomenon, prevent iron-based particles from settling and clumping, ensure that the components of the binder are fully mixed, reduce stirring "dead zones", and improve the uniformity of raw material mixing.

Detailed Implementation

[0012] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0013] Example: A mixing device for iron-based adhesives like Figure 1-4 As shown, a stirring device for an iron-based adhesive has the following specific structure: A mixing tank 10 with an open top surface has several evenly distributed support legs 101 fixedly installed at the bottom. A feed pipe 102 is integrally fixedly installed at the bottom of the mixing tank 10, and a valve is provided at the top of the feed pipe 102. A mixing assembly 20 is provided inside the mixing tank 10. The mixing assembly 20 is powered by a drive assembly 30. Several convex ribs arranged in a circular array are fixedly installed inside the mixing tank 10. The cross-section of the convex ribs is triangular.

[0014] The working principle described above is as follows: When using this device, the iron-based adhesive is fed directly into the top opening of the mixing tank 10. The drive component 30 outputs power to drive the mixing component 20 inside the mixing tank 10 to rotate, thus mixing the iron-based adhesive raw materials in the mixing tank 10. After mixing is completed, the valve at the top of the discharge pipe 102 is opened, and the mixed material is discharged along the discharge pipe 102. The operation is simple and convenient.

[0015] The stirring assembly 20 includes: Mounting bracket 201 is fixedly mounted on the top surface of the mixing tank 10; A stirring shaft 202 is provided at the center of the top of the mounting frame 201 and connected to its bearing. The stirring shaft 202 extends vertically through the top of the mounting frame 201 and is connected to its bearing. The drive assembly 30 is fixedly connected to the stirring shaft 202, and the lower end of the stirring shaft 202 extends into the mixing tank 10. A stirring rod 203 is fixedly installed on the outer periphery of the stirring shaft 202, and several evenly distributed stirring rods 203 are divided into upper and lower groups. The stirring rods 203 are inclined upwards away from the stirring shaft, with an inclination angle of 15°-30°, preferably 20°. This structure can push the raw materials in the upper part of the mixing tank downwards, avoiding the accumulation of raw materials in the upper part of the tank, and at the same time guide the raw materials to flow towards the stirring shaft, enhancing the mixing effect in the central area.

[0016] Mounting bracket 201 is fixed to the top surface of mixing tank 10, providing stable support for stirring shaft 202. Stirring shaft 202 is connected to mounting bracket 201 through bearings, which ensures that stirring shaft 202 can rotate flexibly and reduces friction loss during rotation. After driving component 30 is fixedly connected to stirring shaft 202, power is directly transmitted to stirring shaft 202, driving it to rotate synchronously. The lower end of stirring shaft 202 extends into mixing tank 10. When the upper and lower sets of stirring rods 203 fixed on the outer periphery rotate with stirring shaft 202, they can synchronously stir iron-based adhesives at different heights in mixing tank 10. The stirring rod 203 located in the upper layer acts on the upper material in the tank, and the stirring rod 203 located in the lower layer acts on the lower material in the tank, avoiding the problem of "thin upper layer and thick lower layer" stratification caused by material settling due to gravity. The upper and lower sets of stirring rods 203 cover the entire height range of the material in the mixing tank 10, which can break the material stratification phenomenon, make the components of the iron-based adhesive fully mixed, reduce the "dead corners" of uneven mixing, and improve the quality of the final product.

[0017] The drive component 30 is a geared motor 301, which is fixedly mounted on the top surface of the mounting bracket 201. The output end of the geared motor 301 is fixedly connected to the upper end of the stirring shaft 202. The geared motor 301 is fixed to the top surface of the mounting bracket 201, and its output end is fixedly connected to the upper end of the stirring shaft 202. After the geared motor 301 starts, it converts the high-speed, low-torque motor power into low-speed, high-torque output power through an internal reduction mechanism, directly driving the stirring shaft 202 to rotate. Iron-based adhesives typically have a certain viscosity, requiring a relatively large torque to drive the stirring component 20 to rotate. The high-torque output characteristic of the geared motor 301 can easily drive the stirring shaft 202 and stirring rod 203 to overcome material resistance and rotate. Simultaneously, the low-speed design avoids material splashing due to excessive stirring speed or low stirring efficiency due to excessively slow speed.

[0018] A spiral stirring blade 40 is fixedly installed on a section of the stirring shaft 202 located inside the mixing tank 10. The spiral stirring blade 40, fixed to the section of the stirring shaft 202 inside the mixing tank 10, generates axial thrust as the stirring shaft 202 rotates. This thrust pushes the iron-based adhesive at the bottom of the mixing tank 10 upwards while simultaneously guiding the material at the top downwards, creating a circulating flow of "bottom material rising and upper material sinking." The axial circulation of the spiral stirring blade 40 works synergistically with the radial stirring of the stirring rod 203. The stirring rod 203 disperses and stirs the material horizontally, while the spiral stirring blade 40 achieves vertical circulation. This combination creates a three-dimensional stirring flow field within the mixing tank 10, breaking down static stratification and allowing the components of the iron-based adhesive to mix thoroughly in a short time. Compared to the radial stirring of a single stirring rod 203, the stirring time is significantly reduced, improving production efficiency.

[0019] An insulating jacket 50 is fixedly installed on the outside of the mixing tank 10, and several evenly distributed electric heating elements 501 are fixedly installed inside the insulating jacket 50. The insulating jacket 50 wraps around the outside of the mixing tank 10, forming a closed insulating space; the electric heating elements 501 are evenly distributed inside the insulating jacket 50, and generate heat when energized, which is transferred to the outer wall of the mixing tank 10, and then transferred to the iron-based adhesive inside the tank through heat conduction through the tank wall, thereby heating the material; at the same time, the insulating jacket 50 can reduce the heat exchange between the mixing tank 10 and the external environment, preventing the temperature of the heated material from dropping rapidly, thus achieving a heat preservation effect. Heating uniformity is ensured: the electric heating elements 501 are evenly distributed along the circumference of the outer wall of the mixing tank 10, which can make the various parts of the outer wall of the mixing tank 10 heat evenly. Then, through heat conduction through the tank wall, the temperature of the material inside the tank is consistent, avoiding the problem of local overheating or local underheating.

[0020] The electric heating elements 501 are evenly distributed along the circumference of the outer wall of the mixing tank 10, and a temperature sensor 502 is fixedly installed at the bottom of the mixing tank 10. The electric heating elements 501 are evenly distributed along the circumference of the outer wall of the mixing tank 10. After being energized, each heating element heats up synchronously, ensuring a uniform temperature at all points along the circumference of the outer wall of the mixing tank 10. Through heat conduction, the temperature of the iron-based adhesive inside the tank becomes uniform along the circumference, avoiding the problem of localized temperature differences ("hot on one side, cold on the other") caused by the concentrated distribution of heating elements. The temperature sensor 502 is fixed at the bottom of the mixing tank 10, directly contacting the material inside, and can collect material temperature data in real time. After linking the temperature sensor 502 with the control system of the electric heating elements 501, when the material temperature is lower than the set value, the system automatically starts heating with the electric heating elements 501; when the temperature reaches the set value, the system automatically stops heating, realizing the control action of "monitoring-heating-heat preservation".
