Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cement production, and particularly relates to a screening machine for cement production. Background Art
[0002] The process of dividing bulk materials into different particle sizes through one or several layers of sieve surfaces is called screening. A screening machine is a vibrating screening mechanical device that uses the relative movement between bulk materials and the sieve surface to enable some particles to pass through the sieve holes and divides materials such as sand, gravel, and crushed stones into different levels according to particle size. The screening process of a screening machine is generally continuous. After the screening raw materials are fed onto the screening machine, the materials smaller than the sieve hole size pass through the sieve holes and are called the undersize product, and the materials larger than the sieve hole size are continuously discharged from the sieve surface.
[0003] In the prior art, during the cement production process, due to various reasons during the crushing process, the sizes of the crushed particles are different. Therefore, it is necessary to screen the produced cement. Due to the different sizes of cement particles, the screening is not sufficient, resulting in a problem that cement particles of various sizes are mixed together. We have developed a screening machine for cement production. Summary of the Utility Model
[0004] Based on this, the purpose of the utility model is to provide a screening machine for cement production to solve the technical problem that during the cement production process, due to various reasons during the crushing process, the sizes of the crushed particles are different. Therefore, it is necessary to screen the produced cement. Due to the different sizes of cement particles, the screening is not sufficient, resulting in a mixture of cement particles of various sizes.
[0005] To achieve the above purpose, the utility model provides the following technical scheme: A screening machine for cement production, including a screening machine main body. Arc-shaped sliding rails are fixedly connected to both sides inside the screening machine main body. A sieve mesh is movably connected to the arc-shaped sliding rails. A lead screw is movably connected to the screening machine main body. A slider is movably connected to the lead screw. A connecting block is fixedly connected to the bottom of the sieve mesh. The slider and the connecting block are fixedly connected by a connecting rod.
[0006] By adopting the above technical scheme, the motor drives the lead screw to rotate. The rotation of the lead screw drives the slider to axially slide. When the slider axially slides, it drives the connecting block and the sieve mesh to reciprocate through the connecting rod. When the sieve mesh moves, it will be limited and guided by the arc-shaped sliding rail, so that both sides of the sieve mesh are in a cyclic inclined state when reciprocating. Thus, the cement on the top of the sieve mesh can be better dispersed, facilitating the screening of cement, and making the cement screening more sufficient with better use effect.
[0007] Furthermore, a first rotating shaft is movably connected inside the connecting block, and connecting rods are movably connected to both ends of the first rotating shaft.
[0008] By adopting the above technical solution, the rotation of the first rotating shaft is driven by the movement of the connecting rod.
[0009] Further, both ends of the slider are fixedly connected with a second rotating shaft, and the second rotating shaft is movably connected with a connecting rod.
[0010] By adopting the above technical solution, the movement of the slider drives the connecting rod movably connected with the second rotating shaft to move.
[0011] Further, one end of the lead screw is movably connected with a motor, and a support frame is fixedly connected to the outside of the motor.
[0012] By adopting the above technical solution, the motor is fixed by the support frame, and the motor drives the lead screw to rotate.
[0013] Further, a discharge port is fixedly connected to the bottom of the screening machine main body, and the bottom of the screening machine main body has a slope.
[0014] By adopting the above technical solution, the screened cement is discharged more smoothly through the slope at the bottom of the screening machine main body.
[0015] Further, support columns are fixedly connected to the bottom of the screening machine main body, and rubber rings are fixed to the outside of the support columns.
[0016] By adopting the above technical solution, the screening machine main body is fixed by the support columns, and the rubber rings on the outside of the support columns can prevent the staff from being bumped and injured.
[0017] In summary, the present utility model mainly has the following beneficial effects: The present utility model drives the lead screw to rotate through the motor, the rotation of the lead screw drives the slider to axially slide, so that when the slider axially slides, the connecting block and the screen are driven by the connecting rod to reciprocate. When the screen moves, it will be limited and guided by the arc-shaped slide rail, so that both sides of the screen are in a cyclic inclined state when the screen reciprocates, so that the cement on the top of the screen is better dispersed, which is convenient for the screening of cement, and thus the cement screening is more sufficient and the use effect is better.

[0025] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.
[0026] A screening machine for cement production, as Figures 1-5 shown, includes a screening machine main body 1. Arc-shaped slide rails 2 are fixedly connected to both sides inside the screening machine main body 1. A sieve mesh 3 is movably connected to the arc-shaped slide rails 2. A lead screw 9 is movably connected to the screening machine main body 1. A slide block 8 is movably connected to the lead screw 9. A connecting block 5 is fixedly connected to the bottom of the sieve mesh 3. The slide block 8 and the connecting block 5 are fixedly connected by a connecting rod 7.
[0027] Please refer to Figure 2 , Figure 4 and Figure 5 . A first rotating shaft 4 is movably connected inside the connecting block 5, and both ends of the first rotating shaft 4 are movably connected to the connecting rod 7. By setting the above structure in the present invention, the first rotating shaft 4 is driven to rotate by the movement of the connecting rod 7.
[0028] Please refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 . Both ends of the slide block 8 are fixedly connected to a second rotating shaft 6, and the second rotating shaft 6 is movably connected to the connecting rod 7. By setting the above structure in the present invention, the connecting rod 7 movably connected to the second rotating shaft 6 is driven to move by the movement of the slide block 8.
[0029] Please refer to Figure 1 , Figure 2 and Figure 3 . One end of the lead screw 9 is movably connected to a motor 10, and a support frame 11 is fixedly connected to the outside of the motor 10. By setting the above structure in the present invention, the motor 10 is fixed by the support frame 11, and the motor 10 drives the lead screw 9 to rotate.
[0030] Please refer to Figure 1 and Figure 2, a discharge port 12 is fixedly connected to the bottom of the screening machine main body 1, and the bottom of the screening machine main body 1 has a slope. By setting the above structure in the present invention, the screened cement can be discharged more smoothly through the slope at the bottom of the screening machine main body 1.
[0031] Please refer to Figure 1 and Figure 2 , a support column 13 is fixedly connected to the bottom of the screening machine main body 1, and a rubber ring is fixed on the outer side of the support column 13. By setting the above structure in the present invention, the screening machine main body 1 is fixed by the support column 13, and the rubber ring on the outer side of the support column 13 can prevent the staff from being bumped and injured.
[0032] The working principle of the present invention is as follows: When in use, after starting the motor 10, the cement to be screened is put into the top of the screening machine main body 1. At this time, the cement is stacked on the top of the screen 3. Since screening holes are provided inside the screen 3, the cement particles that meet the standard size are discharged from the screening holes;
[0033] At this time, the motor 10 starts to drive the screw rod to rotate, and the rotation of the screw rod drives the slider to axially slide. Thus, when the slider axially slides, it drives the connecting block 5 and the screen 3 to reciprocate through the connecting rod 7;
[0034] At this time, since both the bottom sides of the screen 3 are slidably connected to the arc-shaped slide rails 2, the reciprocating movement of the screen 3 will be limited and guided by the two groups of arc-shaped slide rails 2. Thus, when the screen 3 reciprocates, its two sides are in a cyclic inclined state, so that the cement on the top of the screen 3 can be better dispersed, facilitating the screening of the cement, and making the cement screening more sufficient;
[0035] The screened cement is discharged from the discharge port 12, completing the cement screening process, and the use effect is good.
