Description

Technical Field

[0001] This application relates to the field of cement production equipment technology, and in particular to a cement production apparatus for blended materials. Background Technology

[0002] Cement is used in building construction. Cement is a powdered hydraulic inorganic binder, and it needs to be stirred and mixed in a mixing drum during the production process.

[0003] A search revealed a patent document with authorization announcement number CN216654390U, which discloses a cement production mixing device, including a frame and a mixing drum. The lower end of the mixing drum is welded to the bottom of the frame via a fixing plate. A shaft tube is rotatably connected inside the mixing drum, extending through the top and bottom of the drum. Several first stirring blades are evenly arranged from top to bottom at both ends of the shaft tube. Each first stirring blade has a second stirring blade on its outer upper end. A high-pressure water pipe located at the top of the mixing drum is connected to the upper right end of the shaft tube. By using the first and second stirring blades in combination, and because the first and second stirring blades have different stirring directions, it is convenient to mix cement in two directions, which helps to improve the uniformity and efficiency of cement mixing. Moreover, both the first and second stirring blades are driven by a single rotating motor, reducing the number of rotating motors used and thus reducing electricity waste.

[0004] In practical use, it was found that in the discharge stage of the existing equipment, due to the viscosity of the mixed cement, the discharge pipe is prone to clumping and blockage, requiring frequent shutdowns for manual unblocking, which seriously affects the continuity of production. In addition, the raw materials at the bottom of the mixing tank are often difficult to discharge completely, resulting in residue problems. This not only reduces the utilization rate of raw materials, but may also affect the quality of the next batch of products due to the deterioration of the residual raw materials. Therefore, we have proposed a mixed cement production device to solve the above problems. Utility Model Content

[0005] The purpose of this application is to address the shortcomings of existing technologies, such as the inability to clear the discharge pipe during material discharge and the inability to fully discharge raw materials, and to propose a mixed cement production device.

[0008] By adopting the above technical solution and setting up a stirring mechanism, the motor can drive the stirring frame and scraper to rotate, so that the stirring frame can stir and mix the raw materials to ensure that they are fully integrated and to ensure the quality of cement. At the same time, the scraper rotates with the frame and adheres to the inner wall of the mixing drum, which can remove the raw materials attached to the drum wall, avoid waste of raw materials and ensure the uniformity of mixing.

[0018] By adopting the above technical solution and setting a striking mechanism, the reciprocating screw can drive the striking rod to rotate, so that the striking rod can periodically strike the striking block at the bottom of the mixing tank, causing the mixing tank to vibrate. This can promote the accumulation of raw materials in the tank towards the discharge pipe, accelerate the discharge speed, and avoid raw material residue.

[0019] A further feature of this application is that a controller is provided on the front side of the functional box, and the controller is electrically connected to the motor and the solenoid valve.

The scraper 302 is adapted to the inner wall of the stirring tank 1.

[0028] Specifically, the gear mechanism includes two bevel gears 8. Both the output shaft of the motor 3 and the right end of the rotating shaft 4 are fixedly fitted with bevel gears 8. The bevel gears 8 are located above the partition plate 101, and the two bevel gears 8 mesh with each other.

[0029] Specifically, the reciprocating mechanism includes a reciprocating lead screw 5 and a lead screw seat 501. The reciprocating lead screw 5 is rotatably mounted on the inner wall of the left side of the function box 2. The right end of the reciprocating lead screw 5 extends to the outside of the function box 2. The lead screw seat 501 is threaded on the reciprocating lead screw 5. The lead screw seat 501 is slidably connected to the seat hole 7. The bottom of the lead screw seat 501 extends to the outside of the seat hole 7. A transmission mechanism is provided between the reciprocating lead screw 5 and the rotating shaft 4.

[0030] Specifically, the transmission mechanism includes two transmission wheels 401 and a transmission belt 402. The transmission wheels 401 are fixedly sleeved on both the reciprocating lead screw 5 and the rotating shaft 4. The transmission wheels 401 are located inside the function box 2.

[0031] Specifically, the unblocking mechanism includes a connecting rod 502 and an unblocking rod 503. The connecting rod 502 is fixedly installed on the bottom right side of the screw seat 501, and the unblocking rod 503 is fixedly installed on the top of the connecting rod 502. The unblocking rod 503 is located inside the discharge pipe 103.

[0032] Specifically, the striking mechanism includes a striking rod 6 and a striking block 601. The striking rod 6 is fixedly installed on the right end of the reciprocating screw 5. The striking block 601 is set at the bottom of the mixing tank 1. The striking block 601 is located on the left side of the discharge pipe 103. The striking rod 6 is adapted to the striking block 601. The striking rod 6 is made of rubber.

[0033] Specifically, a controller is installed on the front side of the function box 2, and the controller is electrically connected to the motor 3 and the solenoid valve.

[0034] In this application, during operation, the mixed cement raw materials are first fed into the mixing drum 1 below the partition 101 through the feed pipe 102. The motor 3 is started, and its output shaft drives the mixing frame 301 to rotate, achieving mixing and blending of the raw materials to ensure cement quality. Simultaneously, the scraper 302 on the outside of the mixing frame 301 rotates and adheres to the inner wall of the mixing drum 1, scraping off any raw materials adhering to the drum wall, preventing waste and ensuring uniform mixing. When the output shaft of the motor 3 rotates, power is transmitted to the rotating shaft 4 through two meshing bevel gears 8, causing the rotating shaft 4 to rotate. The rotating shaft 4, through the transmission wheel 401 and the transmission belt 402, drives the reciprocating screw 5 to rotate. Since the screw seat 501 is threadedly connected to the reciprocating screw 5 and slidably connected to the seat hole 7, the rotation of the reciprocating screw 5 causes the screw seat 501 to rotate. 1. The screw seat 501 slides back and forth along the seat hole 7. The screw seat 501 drives the unblocking rod 503 to move back and forth in the discharge pipe 103 through the connecting rod 502. This can unblock the discharge pipe 103 in real time, prevent the raw materials from clumping and blocking in the discharge pipe 103, and ensure smooth discharge. At the same time as the reciprocating screw 5 rotates, it drives the striking rod 6 to rotate synchronously. The striking rod 6 can periodically strike the striking block 601 at the bottom of the mixing tank 1, which can make the mixing tank 1 vibrate. This can promote the raw materials in the tank to gather in the discharge pipe 103, speed up the discharge speed, and avoid the purpose of raw material residue. The controller on the front side of the function box 2 is electrically connected to the motor 3 and the solenoid valve. It can control the start and stop of the motor 3 to adjust the mixing time according to the production needs. When the mixing is completed, the controller controls the solenoid valve to open, and the mixed cement is discharged through the discharge pipe 103, realizing automated production and improving production efficiency.
