Technical Field

[0001] The utility model relates to the technical field of screening equipment, in particular to cement clinker screening equipment. Background Art

[0002] Cement clinker is a semi-finished product made from limestone, clay, and iron as the main raw materials. It is mixed into raw meal in appropriate proportions, burned until partially or completely melted, and cooled. The cement clinker needs to be ground into small particles and then screened to remove larger particles in the ground cement clinker.

[0003] For example, the utility model patent with Chinese patent number CN218962732U discloses a cement clinker screening device, comprising a box body and a screen, wherein the box body is provided with a feed port, and the box body is also provided with a knocking assembly, the knocking assembly comprising a movable rod and a through hole provided on the box body that matches the movable rod, one end of the movable rod extending through the through hole into the box body and close to the screen, and the end of the movable rod extending into the box body has a knocking head, and the box body is also provided with a driving assembly that drives the movable rod to move back and forth in a vertical direction, the driving assembly comprising a turntable, and a reducing block provided on a side of the turntable close to the movable rod, the reducing block having a guide surface that abuts the movable rod, and the distance between the guide surface and a side of the turntable close to the movable rod gradually increases or decreases along the circumference of the turntable, and the driving assembly also comprises a first elastic member that drives the movable rod to maintain abutment with the turntable. This utility model solves the technical problem of cement clinker accumulating on the screen mesh causing mesh clogging, and produces the technical effect of avoiding screen clogging, reducing the number of maintenance shutdowns, and improving screening efficiency.

[0004] Although the above-mentioned device can use the knocking component to hit the cement clinker particles retained on the screen, so that the cement clinker particles are broken and pass through the mesh on the screen, our company has found during use that the knocking component can indeed hit the cement clinker particles retained on the screen, which can indeed break some of the cement clinker particles, but at the same time, some cement clinker particles will be knocked into the mesh, causing the cement clinker particles to be stuck in the mesh and unable to fall off, which will also cause the mesh on the screen to be blocked. Subsequently, the staff will still need to shut down the machine for maintenance and clean up the cement clinker particles blocked in the mesh, which increases the labor burden of the staff. Utility Model Content

[0005] The utility model discloses a cement clinker screening device, which solves the problem that when a knocking component hits cement clinker particles retained on the screen, some cement clinker particles may be knocked into the mesh, causing the cement clinker particles to be stuck in the mesh and unable to fall off.

[0006] In order to solve the above technical problems, the present invention specifically adopts the following technical solutions:

[0007] A cement clinker screening device comprises a box body, one side of the box body is connected to a feed hopper, a screening plate is fixed at an angle on the side of the box body close to the feed hopper, the lower side of the screening plate is away from the feed hopper, a fixed frame is fixed in the box body below the lower side of the screening plate, a filter plate that can be moved to the outside of the fixed frame passes through one side of the fixed frame, an electric telescopic rod for driving the filter plate is provided in the box body; a pressing plate that can enter the fixed frame is provided in the box body, and a No. 1 hydraulic rod for driving the pressing plate is provided on the box body; a lifting plate is provided on one side of the fixed frame above the filter plate, a plug rod that is compatible with the filter holes on the filter plate is fixed to the bottom of the lifting plate, and an automatic telescopic rod for driving the lifting plate is provided in the box body.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] After the cement clinker particles are continuously discharged into the box through the feed hopper, the cement clinker particles fall on the screening plate and slide down, while some smaller cement clinker particles fall down through the sieve holes on the screening plate, while larger cement clinker particles slide through the screening plate and fall into the fixed frame; when the larger cement clinker particles enter the fixed frame, they are carried by the filter plate, and then the No. 1 hydraulic rod is activated to move the pressure plate downward into the fixed frame. The pressure plate can cooperate with the filter plate to crush the larger cement clinker particles, and the crushed cement clinker particles can fall down through the filter holes on the filter plate; when some cement clinker particles are pressed to the filter holes on the filter plate After the filter is in, the electric telescopic rod can be started to move the filter plate outside the fixed frame, and the filter plate is located directly under the lifting plate. The automatic telescopic rod is then started to make the lifting plate drive the insertion rod to move downward. After the insertion rod is inserted into the filter holes on the filter plate, the cement clinker particles blocked in the filter holes are dredged, and the cement clinker particles fall downward, and then the lifting plate and the filter plate are restored. The utility model can effectively squeeze and crush larger cement clinker particles, and can effectively dredge the cement clinker particles blocked in the filter holes of the filter plate during the squeezing and crushing, without the need for staff to stop the machine for maintenance, and avoids affecting the efficiency of the subsequent normal screening of cement clinker particles.

[0015] The specific contents of the utility model are described in detail below with reference to the accompanying drawings and embodiments.

[0016] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the utility model provides a cement clinker screening equipment, including a box body 1, one side of the box body 1 is connected to a feed hopper 2, a screening plate is fixed on the side of the box body 1 close to the feed hopper 2 in an inclined manner, and the lower side of the screening plate is away from the feed hopper 2, a fixed frame 4 is fixed in the box body 1 below the lower side of the screening plate, a filter plate 41 that can be moved to the outside of the fixed frame 4 is penetrated by one side of the fixed frame 4, and an electric telescopic rod 42 for driving the filter plate 41 is provided in the box body 1; a pressing plate 5 that can enter the fixed frame 4 is provided in the box body 1, and a No. 1 hydraulic rod 51 for driving the pressing plate 5 is provided on the box body 1; a lifting plate 6 is provided on one side of the fixed frame 4 above the filter plate 41, and a plug rod 61 that is adapted to the filter holes on the filter plate 41 is fixed to the bottom of the lifting plate 6, and an automatic telescopic rod 62 for driving the lifting plate 6 is provided in the box body 1.

[0017] like Figure 1As shown, the screening plate assembly includes an inclined block 3 fixed on one side of the box body 1 close to the feed hopper 2, a sieve plate 31 is fixed on the other side of the inclined block 3, an inclined plate 32 is fixed on the other side of the sieve plate 31, and the fixed frame 4 is located below the inclined plate 32; an inclined guide plate 63 is fixed to the bottom surface of the inclined plate 32, the guide plate 63 is inclined toward the side away from the fixed frame 4 and is located below the sieve plate 31, the fixed end of the automatic telescopic rod 62 is fixed to the bottom of the guide plate 63, and the telescopic end of the automatic telescopic rod 62 is connected to the top of the lifting plate 6. When the cement clinker particles enter the box 1 and fall on the sieve plate 31, some smaller cement clinker particles can pass through the sieve holes on the sieve plate 31 and fall downward in the process of the cement clinker particles sliding down on the sieve plate 31, while some larger cement clinker particles slide onto the inclined plate 32 and then enter the fixed frame 4, completing the screening of larger and smaller cement clinker particles; the setting of the guide plate 63 can prevent the cement clinker particles that pass through the sieve holes on the sieve plate 31 from falling on the lifting plate 6. The guide plate 63 can guide all the cement clinker particles to the side of the box 1 close to the feed hopper 2, so that the cement clinker particles fall downward.

[0018] like Figure 1 and Figure 4 As shown, a vertical plate 64 is fixed to the bottom of the guide plate 63. The side of the vertical plate 64 near the fixed frame 4 is connected to the fixed end of the electric telescopic rod 42. The telescopic end of the electric telescopic rod 42 is fixed to the side of the filter plate 41 located outside the fixed frame 4. A supporting rod 43 is fixed inside the fixed frame 4 and contacts the bottom of the filter plate 41. The vertical plate 64 increases the stability of the guide plate 63. At least two electric telescopic rods 42 are fixed to the vertical plate 64 to better drive the movement of the filter plate 41. The support rod 43 supports the filter plate 41 when the pressing plate 5 squeezes the cement clinker particles on the filter plate 41, thereby increasing the stability of the filter plate 41.

[0019] like Figure 1 and Figure 4As shown, a fixed rod 45 is fixed to one side of the fixed frame 4 close to the electric telescopic rod 42, and a No. 2 hydraulic rod 46 is fixed to the top of the fixed rod 45. The telescopic end of the No. 2 hydraulic rod 46 is fixed to a movable plate 47 located below the filter plate 41, and the movable plate 47 corresponds to the lifting plate 6; a cleaning plate 44 located outside the fixed frame 4 is fixed to the bottom of the filter plate 41. When cement clinker particles are clogged in the filter holes on the filter plate 41, the electric telescopic rod 42 is started to move the filter plate 41 outside the fixed frame 4, and the filter plate 41 is located between the movable plate 47 and the lifting plate 6. The No. 2 hydraulic rod 46 is started to move the movable plate 47 upward so that the top of the movable plate 47 contacts the bottom of the filter plate 41; then the automatic telescopic rod 62 is started to move the lifting plate 6 downward (the number of automatic telescopic rods 62 is at least two), and the insertion rod 61 is inserted into the filter holes on the filter plate 41. 61 cooperates with the movable plate 47 to crush the cement clinker particles blocked in the filter holes; when the cement clinker particles blocked in the filter holes are broken, the movable plate 47 moves downward, and then the automatic telescopic rod 62 starts the lifting plate 6 to recover, and then the electric telescopic rod 42 drives the filter plate 41 to recover. During the recovery process of the filter plate 41, the cleaning plate 44 contacts the top surface of the movable plate 47, pushing the cement clinker particles accumulated on the top surface of the movable plate 47, causing the cement clinker particles on the top surface of the movable plate 47 to fall downward.

[0020] like Figure 1 As shown, the bottom of the pressing plate 5 is fixed with a protrusion 52, and the top of the pressing plate 5 is fixed to the side close to the screening plate, which is fixed to a baffle 53 that passes through the top of the box body 1. When the pressing plate 5 moves downward into the fixed frame 4, the baffle 53 moves downward and blocks the side of the inclined plate 32 away from the screen plate 31, preventing the cement clinker particles on the inclined plate 32 from continuing to enter the fixed frame 4; the protrusion 52 can cooperate with the pressing plate 5 to effectively squeeze and crush the cement clinker particles accumulated on the filter plate 41.

[0021] like Figure 1 As shown, the box body 1 is provided with a connecting plate 7 located above the sieve plate 31, and a cleaning rod 71 corresponding to the sieve holes on the sieve plate 31 is fixed to the bottom of the connecting plate 7. A third hydraulic rod 72 for driving the connecting plate 7 is provided on the box body 1. When cement clinker particles are blocked in the sieve holes on the sieve plate 31, the third hydraulic rod 72 can be activated to cause the connecting plate 7 to drive the cleaning rod 71 to move downward. After the cleaning rod 71 is inserted into the sieve holes on the sieve plate 31, the cement clinker particles blocked in the sieve holes on the sieve plate 31 are cleared; the fixed ends of the first hydraulic rod 51 and the third hydraulic rod 72 respectively pass through the top of the box body 1, the telescopic end of the first hydraulic rod 51 is connected to the top of the pressure plate 5, and the telescopic end of the third hydraulic rod 72 is connected to the top of the connecting plate 7.

[0022] like Figure 1 and Figure 4As shown, a fixed plate 8 is fixed on the side of the box body 1 close to the feed hopper 2, and a collecting frame 81 is slidably connected to the fixed plate 8, which passes through the box body 1 and is located below the guide plate 63. The collecting frame 81 is located on one side of the box body 1 and contacts the vertical plate 64. A limiting plate 82 is fixed on the fixed plate 8; the fixed frame 4 is connected to a feed frame 48 that passes through the box body 1. When the cement clinker particles in the sieve holes on the sieve plate 31 are dredged, the staff can push the collecting frame 81 into the box body 1 so that the cement clinker particles falling downward are collected in the collecting frame 81. When the cement clinker particles are collected, the staff will move the collecting frame 81 outside the box body 1. The side of the collecting frame 81 close to the vertical plate 64 can seal the box body 1. The limiting plate 82 can be made of a magnet, and the collecting frame 81 is made of steel, so that after the collecting frame 81 is adsorbed on the limiting plate 82, it can prevent the collecting frame 81 from moving at will; the staff can take out the cement clinker particles in the collecting frame 81. After coming out, it is put into the fixed frame 4 through the feeding frame 48, so that the cement clinker particles fall on the filter plate 41, so that the subsequent insertion rod 61 and the movable plate 47 can cooperate with each other to crush the cement clinker particles; the top of the filter plate 41 is fixed with a stopper located in the opening on the fixed frame 4 to prevent the cement clinker particles falling on the filter plate 41 from moving outside the fixed frame 4 through the opening on the fixed frame 4; at the same time, four stops can also be set on the top surface of the filter plate 41, and the four stops are distributed in a rectangular array to limit the cement clinker particles falling on the top of the filter plate 41. The specific setting depends on the actual situation during use.

[0023] like Figure 1 As shown, a vibrator 9 with a vibrating end connected to the bottom of the inclined block 3 is fixed in the box body 1, and guide blocks 11 are fixed on both sides of the bottom of the box body 1. When the cement clinker particles fall on the inclined block 3, the vibrator 9 can be started to make the inclined block 3 drive the screen plate 31 to vibrate together, so as to better screen the cement clinker particles and make the cement clinker particles slide downward more quickly; the discharge end at the bottom of the box body 1 is located between the two guide blocks 11. When the cement clinker particles fall downward, the two guide blocks 11 can help the cement clinker particles slide toward the discharge end at the bottom of the box body 1.

[0024] During use, the cement clinker particles are discharged into the box body 1 through the feed hopper 2. After the cement clinker particles fall on the screen plate 31, the smaller cement clinker particles (that meet the use specifications) can fall downward through the sieve holes on the screen plate 31, while the larger cement clinker particles slide through the screen plate 31 and the inclined plate 32 into the fixed frame 4; when the larger cement clinker particles enter the fixed frame 4, they fall on the top surface of the filter plate 41, and then the No. 1 hydraulic rod 51 is activated to drive the pressing plate 5 to move downward into the fixed frame 4, and the pressing plate 5 can cooperate with the filter plate 41 to squeeze and crush the larger cement clinker particles. The crushed cement clinker particles fall downward through the filter holes on the filter plate 41; when the filter holes on the filter plate 41 are clogged with cement clinker particles, the electric telescopic rod 42 can be started to retract the telescopic end of the electric telescopic rod 42 to move the filter plate 41 outside the fixed frame 4, so that the filter plate 41 corresponds to the lifting plate 6, and then the automatic telescopic rod 62 is started to make the lifting plate 6 drive the insertion rod 61 to move downward, and the insertion rod 61 is inserted into the filter holes on the filter plate 41, completing the dredging of the cement clinker particles clogged in the filter holes, and then the lifting plate 6 and the filter plate 41 can be restored.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
