Description

Technical Field

[0001] This utility model relates to the field of cement production technology, and more specifically to a double-layer screen structure for a cement feeding station. Background Technology

[0002] In cement production, screening is a crucial quality control step. Cement fineness is an important indicator of cement quality, affecting not only its performance but also its overall quality in relation to production processes, technology, equipment, energy consumption, and cost.

[0003] The shortcomings of existing technology: Under the current technology, when cement feeding plants screen cement, they generally use screens to directly separate impurities from the cement. However, these impurities are composed of particles of different sizes. At present, the uniform separation without stratification will result in poor separation effect and affect the quality of cement. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a double-layer screen structure for cement feeding stations to solve the problems existing in the background art.

The top of the base is fixedly installed with a sliding frame, and two sliding frames are provided corresponding to the support feet. The support feet and the sliding frame are slidably connected.

[0008] Preferably, a guide rod is fixedly connected to the front side of the mounting plate, and multiple guide rods are provided. A limit strip is fixedly connected to one end of the guide rod. The receiving frame is sleeved on the surface of the guide rod, and a compression spring is sleeved on the surface of the guide rod. One end of the compression spring is fixedly connected to the front side of the mounting plate, and the other end of the compression spring is fixedly connected to the rear side of the receiving frame.

[0009] Preferably, the front side of the mounting plate is fixedly connected to an inclined guide plate, a feed hopper, and a support frame. The guide plate is located between the first screen plate and the second screen plate. The distance between the guide plate and the ground decreases from left to right.

[0012] In use, the traction block and the rotating wheel work together to drive the receiving frame, the first screen plate, and the second screen plate to continuously reciprocate in the horizontal direction. After the worker puts the cement into the first screen plate, the cement can move sequentially along the first screen plate, the guide plate, and the second screen plate. During this process, large particles of impurities in the cement enter the first collection shell, the cement enters the second collection shell, and small particles of impurities in the cement slide into the third collection shell. This design separates large and small particles of impurities from the cement in two steps through a double-layer screening method, which improves the screening effect and improves the quality of the cement.

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The double-layer screen structure of the cement feeding station involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] This utility model provides a double-layer screen structure for a cement feeding station, including a base 1, an mounting plate 2 and a motor 4 fixedly installed on the top of the base 1, a transmission rod 5 rotatably installed on the top of the base 1, a motion component 3 also installed on the top of the base 1, and a traction component 6 fixedly installed at the top of the transmission rod 5. The motion component 3 is used to perform double-layer filtration of cement, the traction component 6 is used to provide power for the shaking of the motion component 3, and the transmission rod 5 is used to transmit the output power of the motor 4 to the traction component 6.

[0021] The motion component 3 includes a first screen plate 31, and a second screen plate 32 is provided at the bottom of the first screen plate 31. Both the first screen plate 31 and the second screen plate 32 are arranged at an inclination. The distance between the first screen plate 31 and the ground decreases from left to right, and the distance between the second screen plate 32 and the ground increases from left to right. The first screen plate 31 and the second screen plate 32 are fixedly connected by a support frame 33.

[0022] Furthermore, the first sieve plate 31 is densely provided with connecting holes 311, which are used to separate large particles of impurities in the cement. A screen 321 is fixedly installed on the second sieve plate 32, which is used to separate small particles of impurities in the cement. Support legs 331 are fixedly connected to the bottom of the receiving frame 33, and two support legs 331 are provided. A sliding frame 14 is fixedly installed on the top of the base 1, and two sliding frames 14 are provided corresponding to the support legs 331. The support legs 331 and the sliding frame 14 are slidably connected, and the cooperation between the support legs 331 and the sliding frame 14 ensures the smooth operation of the receiving frame 33. To ensure stability during operation, a guide rod 24 is fixedly connected to the front side of the mounting plate 2. Multiple guide rods 24 are provided. One end of the guide rod 24 is fixedly connected to a limit strip 25. The support frame 33 is sleeved on the surface of the guide rod 24. The support frame 33 and the guide rod 24 form a sliding guide fit along the axis of the guide rod 24. A compression spring 26 is sleeved on the surface of the guide rod 24. One end of the compression spring 26 is fixedly connected to the front side of the mounting plate 2, and the other end of the compression spring 26 is fixedly connected to the rear side of the support frame 33. The elastic force of the compression spring 26 can drive the support frame 33 to move away from the mounting plate 2.

[0023] Furthermore, the front side of the mounting plate 2 is fixedly connected to an inclined guide plate 21, a feed hopper 22, and a support frame 23. The guide plate 21 is located between the first screen plate 31 and the second screen plate 32. The distance between the guide plate 21 and the ground decreases from left to right. The top of the base 1 is equipped with a second collection shell 12 and a third collection shell 13. The top of the support frame 23 is equipped with a first collection shell 11. The first collection shell 11 is used to collect large particles of impurities in the cement, the second collection shell 12 is used to collect cement, and the third collection shell 13 is used to collect small particles of impurities in the cement.

[0024] Furthermore, the traction assembly 6 includes a rotating plate 61, which is fixedly installed on the top of the transmission rod 5. A traction block 62 is fixedly connected to the top of the rotating plate 61. Four traction blocks 62 are evenly arranged. A triggering inclined surface 621 and a triggering plane 622 are provided on one side of the traction block 62. A positioning frame 332 is fixedly connected to the front side of the receiving frame 33. A rotating wheel 34 is rotatably installed on the positioning frame 332. A power transmission component 41 is provided between the output end of the motor 4 and the transmission rod 5. The power transmission component 41 is used to convert the output power of the motor 4 into the rotational force of the transmission rod 5. Preferably, the power transmission component 41 is a belt drive structure. During the rotation of the traction block 62 around the axis of the transmission rod 5, the triggering inclined surface 621 first contacts the rotating wheel 34. After the triggering inclined surface 621 separates from the rotating wheel 34, the triggering plane 622 contacts the rotating wheel 34.

[0025] The working principle of this utility model is as follows: In actual operation, the motor 4 is turned on, and the motor 4 drives the transmission rod 5 to rotate around its own axis through the power transmission component 41. The rotation of the transmission rod 5 drives the rotating plate 61 and the traction block 62 to rotate synchronously around the axis of the transmission rod 5. During the rotation of the traction block 62, the triggering inclined surface 621 first contacts the rotating wheel 34. The triggering inclined surface 621 pushes the receiving frame 33 as a whole to move along the guide rod 24 towards the mounting plate 2 through the rotating wheel 34. The compression spring 26 contracts under the compression of the receiving frame 33, and the elastic force of the compression spring 26 increases. When the triggering inclined surface 621 separates from the rotating wheel 34, the triggering plane 622 contacts the rotating wheel 34. At this time, the receiving frame 33 remains stationary. When the triggering plane 622 separates from the rotating wheel 34, the elastic force of the compression spring 26 drives the receiving frame 33 to move away from the mounting plate 2. This cycle repeats, and the receiving frame 33, the first screen plate 31 and the second screen plate 32 as a whole continuously sway back and forth in the horizontal direction.

[0026] The worker feeds cement from the feed hopper 22 to the first screen plate 31. As the first screen plate 31 shakes, the cement passes through the connecting hole 311 and enters the guide plate 21. Large particles of impurities in the cement cannot pass through the connecting hole 311 and slide down the first screen plate 31 into the first collection shell 11 under their own gravity. The cement then enters the second screen plate 32 along the guide plate 21 under its own gravity. As the second screen plate 32 shakes, the cement passes through the screen 321 and enters the second collection shell 12. Small particles of impurities in the cement cannot pass through the screen 321 and slide down the second screen plate 32 into the third collection shell 13 under their own gravity.
