Detailed Implementation

[0016] 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.

[0017] Please see Figure 1-4 This utility model provides a technical solution: A convection homogenization device for a cementitious material includes a homogenization tank 1, heat source components 2 on both sides of the homogenization tank 1, and a homogenization stirring mechanism 3 on the top of the homogenization tank 1. The homogenization stirring mechanism 3 includes: The stirring assembly 31 includes an equipment box 311 installed on the top of the homogenization tank 1. A stirring motor 312 is fixedly connected to the top of the equipment box 311. One end of the output shaft of the stirring motor 312 is fixedly connected to a connecting rod 313 via a coupling. A worm gear 314 is fixedly connected to the surface of the connecting rod 313. A stirring rod 315 is slidably connected to the surface of the connecting rod 313. One end of the stirring rod 315 extends into the interior of the homogenization tank 1 and is fixedly connected to multiple sets of stirring plates 316. The linkage component 32 is located inside the equipment box 311 and is used to drive the stirring plate 316 to slide up and down.

[0018] The stirring motor 312 is a three-phase asynchronous motor; Multiple flow channels are formed on the surface of the stirring plate 316; The connecting rod 313 rotates inside the equipment box 311. A limiting strip is provided on the surface of the connecting rod 313, and a matching limiting groove is provided inside the stirring rod 315. The limiting groove and the limiting strip can limit the up and down sliding of the stirring rod 315. At the same time, when the connecting rod 313 rotates, the limiting strip and the limiting groove can drive the stirring rod 315 to rotate synchronously. The stirring rod 315 slides and rotates on the top of the homogenization tank 1; By setting up a homogenization and stirring mechanism 3, when the stirring motor 312 drives the connecting rod 313 to rotate, the connecting rod 313 simultaneously drives the worm gear 314 and the stirring rod 315 to rotate. The stirring rod 315 stirs the cementitious material in the homogenization tank 1 through the stirring plate 316. At the same time, the worm gear 314 drives the worm wheel 321 to rotate, and the worm wheel 321 drives the linkage block 323 to rotate through the linkage rod 322. The linkage block 323 drives the linkage plate 324 to move up and down through the transmission assembly 4. The linkage plate 324 drives the stirring rod 315 to slide up and down along the connecting rod 313, so that the stirring plate 316 moves up and down while rotating, thereby expanding the stirring range and improving the homogenization effect.

[0019] In this embodiment, the linkage assembly 32 includes a worm gear 321 rotatably mounted on the inner wall of the equipment box 311. The surface of the worm gear 321 meshes with the surface of the worm 314. A linkage rod 322 is fixedly connected to one side of the worm gear 321. A linkage block 323 is fixedly connected to one end of the linkage rod 322. The surface of the linkage block 323 drives the linkage plate 324 to slide up and down through the transmission assembly 4. The interior of the linkage plate 324 is rotatably connected to the top end of the stirring rod 315.

[0020] In this embodiment, the transmission assembly 4 includes a limiting rod 41 installed at the bottom of the inner cavity of the equipment box 311. A transmission plate 42 is slidably connected to the surface of the limiting rod 41. A transmission groove 43 is opened on the surface of the transmission plate 42. The inner surface of the transmission groove 43 is slidably connected to the surface of the linkage block 323. A connecting plate 44 is fixedly connected to the bottom of the transmission plate 42. The bottom end of the connecting plate 44 is fixedly connected to one end of the linkage plate 324.

[0021] The limiting rod 41 is used to limit the up and down sliding of the transmission plate 42; In this embodiment, a feed inlet 5 is installed at the top of the homogenization tank 1, and a discharge outlet 6 is installed at the bottom of the homogenization tank 1. An electromagnetic valve is installed inside the discharge outlet 6.

[0022] In this embodiment, the heat source assembly 2 includes a support plate 21 installed on both sides of the homogenization tank 1. A homogenization fan 22 and a heating device 23 are installed on the top of the support plate 21. The air outlet pipe of the homogenization fan 22 is fixedly connected to one side of the heating device 23, and the other side of the heating device 23 is fixedly connected to the surface of the homogenization tank 1 through a connecting pipe 24.

[0023] The homogenizing fan 22 is a centrifugal fan; Heating device 23 uses an electric heating tube, with a built-in temperature sensor and temperature control module working together to achieve constant temperature control; In this embodiment, a regulating valve 7 is installed on the surface of the connecting pipe 24, and a control panel 8 is installed on the surface of the homogenizing tank 1. The control panel 8 is used to electrically connect and control the operation of the stirring motor 312, the homogenizing fan 22, the heating device 23, and the solenoid valve.

[0024] The regulating valve 7 can be set to manual control or automatic adjustment, and is used to regulate the air intake of the connecting pipe 24; By setting up the heat source component 2, the homogenizing fan 22 sends air into the heating device 23. After the heating device 23 heats the air, the hot air enters the homogenizing tank 1 through the connecting pipe 24. Together with the stirring component 31, the cementitious material is heated evenly, avoiding the impact of uneven temperature on the homogenization quality. At the same time, the hot air can promote the convection of the cementitious material, further improving the homogenization efficiency.

[0025] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0026] In use, the cementitious material is fed into the homogenization tank 1 through the feed inlet 5. The stirring motor 312, homogenization fan 22, and heating device 23 are started through the control panel 8. The stirring motor 312 drives the connecting rod 313, worm gear 314, and stirring rod 315 to rotate. The stirring plate 316 rotates to stir the cementitious material. Simultaneously, the worm gear 314 drives the worm wheel 321 to rotate. The worm wheel 321 drives the linkage block 323 to perform circular motion through the linkage rod 322. The linkage block 323 slides on the inner surface of the transmission groove 43. This causes the transmission plate 42 to slide on the surface of the limiting rod 41. The transmission plate 42 drives the connecting plate 44 and the linkage plate 324 to move up and down, so that the stirring rod 315 and the stirring plate 316 slide up and down synchronously, expanding the stirring range. During this process, the homogenizing blower 22 sends air into the heating device 23 for heating. The hot air enters the homogenizing tank 1 through the connecting pipe 24, which, together with the stirring, makes the material heat up evenly and promotes convection. After homogenization is completed, the solenoid valve is opened through the control panel 8, and the homogenized material is discharged from the discharge port 6.
