Description

Technical Field

[0001] The invention belongs to the field of cement processing, and in particular relates to screening equipment for cement processing. Background Art

[0002] The main raw material of cement is limestone, and the mined limestone is mostly in large blocks. Due to its high hardness, direct use will increase the difficulty and energy consumption of subsequent processes.

[0003] In cement processing, large pieces of material are broken into smaller particles by crushers. This process is particularly important for limestone, because it is not just a simple crushing, but it needs to go through multiple stages of crushing to ensure the final particle size is appropriate, which helps to improve the subsequent grinding efficiency.

[0004] Because limestone needs to be crushed at multiple stages, only particles that meet the requirements will enter the next process, so screening is a necessary processing step. Most existing screening devices are achieved through screens accompanied by vibration. However, since the particles of limestone are very fine after multiple crushing, the screen is easily blocked, which greatly reduces the screening efficiency. Cleaning the screen requires shutdown, so the existing devices have many inconveniences when screening. Summary of the invention

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a screening device for cement processing provided by an embodiment of the present invention includes a frame 1, a power box 2 is arranged on one side of the top of the frame 1, and further includes:

[0030] The screening box 3 is an open structure at the top and the bottom, a plate 4 is fixedly provided on the other side of the top of the frame 1, a guide rail frame 5 is fixedly provided between the power box 2 and the plate 4, the screening box 3 is located between the guide rail frames 5, the output end of the power box 2 is a crank rocker structure 6 connected to the screening box 3, the power box 2 is used to drive the screening box 3 to reciprocate on the guide rail frame 5 through the crank rocker structure 6, and an inclined material guide plate 7 is fixedly connected to the frame 1, and the material guide plate 7 is located at the bottom of the screening box 3;

[0031] A separation component 8; the separation component 8 is located in the screening box 3, and the separation component 8 includes a drum 801 rotatably arranged in the screening box 3, and a plurality of evenly arranged sieve holes 802 are provided on the drum 801. The separation component 8 also includes two arc-shaped blocking blocks 803 and two inclined blocking blocks 804. The two arc-shaped blocking blocks 803 are arranged at intervals along the axial direction of the drum 801 and are fixedly connected to the inner walls on both sides of the screening box 3. The two inclined blocking blocks 804 are arranged at intervals along the radial direction of the drum 801 and are fixed to the inner walls on both sides of the screening box 3. The heights of the arc-shaped blocking blocks 803 and the inclined blocking blocks 804 are both greater than the height of the axis of the drum 801. The arc-shaped blocking blocks 803 and the inclined blocking blocks 804 are both matched with the surface of the drum 801. The arc-shaped blocking blocks 803, the inclined blocking blocks 804, the top surface of the drum 801 and the inner wall of the screening box 3 constitute a silo.

[0032] Main rollers 9 cooperating with two guide rail frames 5 are arranged on both sides of the screening box 3. A ratchet structure with a directional rotation function is arranged on the main roller 9. The main roller 9 is transmission-connected to the drum 801 via a reducer 10 fixedly arranged on the outer surface of the screening box 3.

[0033] In one embodiment of the present invention, the driving mode of the present device is the same as that of a conventional screening device, both of which utilize the rapid reciprocating motion of the screening box 3 to achieve the screening of limestone particles. The special feature is that by utilizing the reciprocating movement characteristics of the screening box 3, combined with a very conventional reducer 10 and a ratchet structure on the main roller 9, the drum 801 in the screening box 3 can be rotated slowly, and the slowly rotating drum 801 can not only realize the switching of the sieve hole 802 area on the drum 801, but also because of the structural characteristics of the drum 801 itself, the limestone particles can be screened twice. When the sieve hole 802 area on the drum 801 can be rotated and switched, even if the sieve hole 802 is blocked, a new sieve hole 802 area can be switched to be responsible for the screening work. This rotary screening method can not only reduce the frequency of cleaning the drum 801, but also make the cleaning work easier. In summary, the present screening device, through the cooperation between simple mechanical structures, while realizing the screening function, also has the characteristics of low cleaning frequency and simplified cleaning.

[0034] It should be noted that although the two screening processes mentioned in this embodiment have no obvious actual effect, except for reducing the loss, they do not play a key role in the quality of screening. When the limestone particles fall into the drum 801 from the sieve hole 802 at the top of the drum 801, they will inevitably gather at the bottom of the drum 801 under the action of gravity. At this time, these limestone particles must fall from the sieve hole 802 at the bottom to the guide plate 7 below. It should be understood that if a sieve hole 802 at the top of the drum 801 is blocked, the material at the blocked part must be Because the pressure is generated from top to bottom, when the sieve hole 802 rotates downward, the material collected in the drum 801 will generate an opposite force from the sieve hole 802, which makes it more likely that the sieve hole 802 will be flushed open. Therefore, the drum 801 can use the force of the material falling during its own screening to reversely clear the blocked sieve hole 802. In addition, one side of the silo in the screening box 3 is provided with a discharge silo door 31 that can be closed or opened, and some materials that do not meet the screening requirements can be easily cleaned through the discharge silo door 31.

[0035] like Figure 1 and Figure 3 As shown, as a preferred embodiment of the present invention, a sub-box body 11 is fixedly connected to the side of the screening box body 3 away from the power box body 2, and sub-rollers 12 that cooperate with the guide rail frame 5 are rotatably provided on both sides of the sub-box body 11, and the sub-box body 11, sub-rollers 12, main rollers 9 and drum 801 are all in the same plane.

[0036] In one case of this embodiment, if the support is provided by the crank rocker structure 6 and the two main rollers 9, this method is obviously unreliable, so the auxiliary box 11 and the auxiliary roller 12 are added, and the main roller 9 and the auxiliary roller 12 cooperate to achieve a more reliable support for the screening box 3, such as Figure 4 , Figure 6As shown, a rectangular opening 13 is provided at the joint between the screening box 3 and the auxiliary box 11, a vertically arranged guide frame 14 is fixedly connected in the auxiliary box 11, a horizontally arranged column 15 is slidably connected to the guide frame 14, a strip plate 16 is fixedly connected to one end of the column 15 facing the rectangular opening 13, a cleaning brush 17 is provided on the strip plate 16, a double-end frame 18 is connected to the other end of the column 15, and both ends of the double-end frame 18 are fixedly connected to a pin shaft 19, and a rotating wheel 20 connected to the auxiliary roller 12 is provided on both sides of the auxiliary box 11, and an elliptical groove 21 matched with the pin shaft 19 is provided on the rotating wheel 20. When the screening box 3 moves back and forth, the rotating wheel 20 and the pin shaft 19 are connected. The cooperation enables the cleaning brush 17 at one end of the column 15 to move back and forth, so that it contacts the surface of the roller 801. The rotational force of the auxiliary roller 12 can drive the wheel 20 to rotate. Through the cooperation of the elliptical groove 21 and the pin 19, the reciprocating operation of the column 15, the double-end frame 18 and the strip plate 16 can be realized, so that when the device is working, the cleaning brush 17 can periodically contact the roller 801, thereby cleaning the sieve holes 802 on the roller 801, so that the roller 801 in the device is rotating and screening while the cleaning brush 17 is also cleaning its surface, further reducing the frequency of cleaning the sieve holes 802, and realizing the self-cleaning function of the device.

[0037] like Figure 4 , Figure 6 and Figure 7 As shown, as a preferred embodiment of the present invention, an elastic partition 22 is fixedly connected to the column 15, the elastic partition 22 is sealed to the inner wall of the auxiliary box 11, the elastic partition 22 is located between the guide frame 14 and the strip plate 16, the elastic partition 22 blocks the internal space of the auxiliary box 11 into a dust-free chamber, and the double-end frame 18 and the rotating wheel 20 are both located in the dust-free chamber.

[0038] In one case of the present embodiment, the elastic barrier 22 not only does not affect the reciprocating movement of the column 15, but also can isolate the structure in the auxiliary box 11 from the inside of the screening box 3, thereby preventing dust from entering and effectively protecting the relevant mechanical structures of the device. In addition, the strip plate 16 and the column 15 are both provided with an air passage 23, and a plurality of air holes are provided on the strip plate 16 on one side of the cleaning brush 17. An air outlet pipe 24 connected to the air passage 23 is fixedly connected to the double-end frame 18, and an air inlet pipe 25 is fixedly provided on the top of the auxiliary box 11. A one-way valve 26 is provided, and a dust cover 27 is fixedly connected to the top of the air inlet pipe 25. Because the dust-free chamber is a relatively sealed space, when the column 15 moves back and forth, the elastic barrier layer 22 will inevitably deform, which causes the pressure in the dust-free chamber to change. Through the cooperation of the air inlet pipe 25 with the one-way valve 26 and the air outlet pipe 24, the outside air can be drawn into the dust-free chamber and sprayed out from the air holes on the strip plate 16 through the air duct 23, which can not only clean the cleaning brush 17 on the strip plate 16, but also has a certain purge function for the sieve hole 802 on the roller 801.

[0039] like Figure 3 , Figure 4 and Figure 6 As shown, as a preferred embodiment of the present invention, a box body 28 is fixedly connected to the side of the screening box body 3 opposite to the rectangular opening 13, an industrial control camera 29 is arranged in the box body 28, a transparent window is fixedly arranged at the joint of the box body 28 and the screening box body 3, and an electromagnetic clutch 30 for transmission connection between the auxiliary roller 12 and the rotating wheel 20 is fixedly connected on both sides of the auxiliary box body 11.

[0040] In one case of this embodiment, the present invention proposes a method for controlling the operation of the cleaning brush 17 based on the above structure, and the specific steps include:

[0041] S100, obtaining a working image through the industrial control camera 29 and preprocessing the image, wherein the working image is an image of the drum 801 captured by the industrial control box through a transparent window;

[0042] S200, using an edge detection algorithm to identify the area belonging to the drum 801 in the working image, and marking the area where the sieve hole 802 is located;

[0043] S300, identifying the sieve hole 802 with a blockage based on the color feature difference, and when the sieve hole 802 has a blockage, performing a color change process on the corresponding mark point;

[0044] S400, calculating the proportion of the color-changed marking points among all the marking points, and when the proportion is greater than a set value, driving the electromagnetic clutch 30 by means of a control instruction, so that the auxiliary roller 12 and the rotating wheel 20 are in a transmission connection state.

[0045] It should be noted that if the electromagnetic clutch 30 is not present, the cleaning brush 17 in the device is always in working condition, which will not only increase the loss, but also obviously is unnecessary to keep it working. The existing computer vision technology can be used to identify whether the sieve holes 802 on the drum 801 are blocked. When the sieve holes 802 in a certain area are blocked to a large extent, the electromagnetic clutch 30 can be controlled by the industrial computer to connect the secondary roller 12 with the rotating wheel 20, thereby realizing the cleaning, purging and other functions mentioned above. When the industrial control camera 29 identifies that the sieve holes 802 on the drum 801 are not blocked or the blockage is relatively small, the electromagnetic clutch 30 is disengaged, thereby cutting off the power transmission between the secondary roller 12 and the rotating wheel 20, so that the cleaning brush 17 is in a stopped state when the screening box 3 moves back and forth. The above method effectively realizes the automatic control of the cleaning brush 17.

[0046] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
