Description

Technical Field

[0001] This utility model belongs to the field of homogenization device technology, and in particular relates to a cement raw material pretreatment homogenization device. Background Technology

[0002] Cement raw materials mainly refer to natural minerals and industrial wastes used to produce cement. Natural minerals include limestone, clay, sandstone, etc., which provide cement with components such as calcium, silicon, aluminum, and iron. Industrial wastes such as fly ash and slag can be added as auxiliary raw materials. These raw materials are pre-treated by crushing, grinding, etc., to become powdered raw meal, and then cement is made through processes such as homogenization and calcination. Homogenization of cement raw materials is to make the raw material composition uniform and stable.

[0003] However, in the operation of existing homogenization devices, there are large homogenization dead zones when the stirring rod rotates. This causes some raw materials to accumulate in the dead zone area because they are not easy to be effectively stirred. As a result, they are not easy to participate in the uniform mixing process, which reduces the overall homogenization effect of the raw materials and results in insufficient uniformity of composition, thus affecting the quality stability of subsequent cement production. Utility Model Content

[0004] The purpose of this utility model is to provide a cement raw material pretreatment homogenization device. By setting up a homogenization section, it solves the problem that in the existing homogenization device, when the stirring rod rotates, there is a large homogenization dead corner, which causes some raw materials to accumulate in the dead corner area because they are not easy to be effectively stirred. This makes it difficult for them to participate in the uniform mixing process, resulting in a decrease in the overall homogenization effect of the raw materials, insufficient component uniformity, and thus affecting the quality stability of subsequent cement production.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a cement raw material pretreatment homogenization device, comprising a rectangular base plate and a homogenization box fixedly connected to the top of the rectangular base plate, and further comprising: a homogenization section disposed inside the homogenization box; and a lifting section installed on the top of the rectangular base plate; wherein the top of the homogenization section is connected to the lifting section.

[0007] Furthermore, the homogenization section includes a homogenization component mounted on a homogenization box; and a lifting component mounted on the homogenization component; wherein the lifting component is installed inside the homogenization box.

[0008] Furthermore, the lifting unit includes a threaded assembly mounted on the top of a rectangular base plate; and a sliding assembly mounted on the threaded assembly; wherein the sliding assembly is connected to the top of the homogenizing assembly.

[0009] Furthermore, the homogenization assembly includes a support frame 1 disposed above the homogenization box. A motor 1 is fixedly connected to the top inner wall of the support frame 1. The output shaft of the motor 1 is fixedly connected to a rotating shaft via a coupling. The bottom of the rotating shaft extends outside the support frame 1. The rotating shaft is rotatably connected to the support frame 1. A rectangular block is fixedly connected to the outer wall of the rotating shaft. A movable ring is slidably connected to the outer wall of the rectangular block. Homogenizing elements are disposed on the movable ring and the rotating shaft. The bottom of the rotating shaft extends into the homogenization box, and the rectangular block and the movable ring are both located inside the homogenization box.

[0010] Furthermore, the lifting assembly includes several rectangular slots formed on the inner wall of the homogenization box. Limiting rods are slidably connected to the inner walls of each of the rectangular slots. The tops of each of the limiting rods are fixedly connected to a support frame. A ring is fixedly connected to the inner wall of the limiting rods on their respective sides. An arc-shaped groove is formed on the inner wall of the ring. Two sliding rods are fixedly connected to the outer wall of the moving ring. The sides of the two sliding rods that are far apart from each other extend into the arc-shaped groove, and both sliding rods are slidably connected to the arc-shaped groove. Four rectangular slots and four limiting rods are provided, and the four rectangular slots and four limiting rods are arranged in a circular array.

[0011] Furthermore, the threaded assembly includes a second support frame fixedly connected to the top of the rectangular base plate. A second motor is fixedly connected to the top of the second support frame. The output shaft of the second motor is fixedly connected to a threaded rod via a coupling. The bottom of the threaded rod passes through the second support frame and is rotatably connected to the rectangular base plate. The threaded rod is rotatably connected to the second support frame. Both the second motor and the threaded rod are located at the central axis of the second support frame.

[0012] Furthermore, the sliding assembly includes a connecting frame threaded onto the outer wall of the threaded rod. The side of the connecting frame away from the second support frame is fixedly connected to the first support frame. Two sliding rods are fixedly connected to the top of the rectangular base plate. The tops of the two sliding rods pass through the connecting frame and are fixedly connected to the second support frame. Both sliding rods are slidably connected to the connecting frame. The two connecting frames are symmetrically arranged with respect to the threaded rod.

[0013] Furthermore, the homogenizing component includes two stirring rods fixedly connected to the outer wall of the moving ring, and a spiral blade is fixedly connected to the outer wall of the rotating shaft; wherein, the two stirring rods are arranged in a mirror image with respect to the rotating shaft, and the spiral blade is located below the two stirring rods.

[0014] This utility model has the following beneficial effects:

[0015] 1. By setting up a homogenization section, when it is necessary to homogenize the raw materials, motor one can be started. Motor one drives the moving ring on the rectangular block to rotate through the rotating shaft, which in turn drives the two stirring rods and the spiral blades to rotate, thus homogenizing the raw materials. Due to the setting of the arc-shaped sliding groove inside the ring, the moving ring moves up and down along the path of the arc-shaped sliding groove under the connection of the sliding rod one when it rotates, which in turn drives the two stirring rods to move up and down while rotating. By driving the stirring rods to move up and down while rotating, the homogenization dead corners caused by the fixed rotation of the traditional stirring rods are broken. This allows the raw materials that are originally easy to accumulate in the dead corner area and difficult to be stirred to fully participate in the mixing during the up and down movement of the stirring rods, thereby improving the overall homogenization effect of the raw materials, ensuring the uniformity of the composition, and providing a reliable guarantee for the quality stability of subsequent cement production.

[0016] 2. By setting up a lifting unit, after homogenization is completed, start motor two on support frame two to drive the threaded rod to rotate. At this time, the two sliding rods will cooperate with the threaded rod and restrict the connecting frame, causing it to move upward with the rotation of the threaded rod, and driving support frame one to move upward until the spiral blades are completely disengaged from the homogenization box. Then, the homogenized raw material in the homogenization box can be taken out. This allows support frame one and spiral blades to move upward and disengage from the homogenization box, avoiding the mixing components from obstructing the removal of the raw material. It facilitates the complete removal of the homogenized raw material quickly and easily, reduces residue, improves the raw material discharge efficiency and cleanliness, and provides convenience for the smooth operation of subsequent processes.

By setting the lifting part 3, the first support frame 211 and the spiral blade 217 can be moved upward to disengage from the homogenization box 112, avoiding the stirring parts from obstructing the removal of raw materials. This allows for convenient and quick removal of the homogenized raw materials, reducing residue, improving the efficiency and cleanliness of raw material discharge, and facilitating the smooth operation of subsequent processes.

[0030] A specific application of this embodiment is as follows: In use, the cement raw material to be homogenized is first poured into the homogenization box 112. When homogenization is required, motor 212 can be started. Motor 212 drives the moving ring 215 on the rectangular block 214 to rotate via the rotating shaft 213, thereby driving the two stirring rods 216 and the spiral blades 217 to rotate, homogenizing the raw material. Due to the arc-shaped groove 224 inside the ring 223, the moving ring 215, when rotating, will follow the path of the arc-shaped groove 224 connected by the sliding rod 225. The material moves up and down, which in turn drives the two stirring rods 216 to move up and down while rotating. After homogenization is completed, the motor 312 on the support frame 311 is started, which drives the threaded rod 313 to rotate. At this time, the two sliding rods 322 will cooperate with the threaded rod 313 and restrict the connecting frame 321, causing it to move upward with the rotation of the threaded rod 313, and drive the support frame 211 to move upward until the spiral blades 217 are completely disengaged from the homogenization box 112. Then the homogenized material in the homogenization box 112 can be taken out.
