Description

Technical Field

[0001] This invention relates to the field of cement clinker grinding technology, and more specifically, to a grinding and processing equipment and process for cement clinker. Background Technology

[0002] Cement clinker grinding is a crucial step in the cement production process. Its main purpose is to grind cement clinker together with an appropriate amount of gypsum and possible admixtures (such as fly ash, slag, etc.) to produce cement powder that meets the requirements. This process directly affects the quality and performance of cement, including strength, setting time, and durability.

[0003] Currently, cement clinker is typically ground using a grinding mill, which consists of two opposing grinding discs. Cement clinker is fed between the two discs and ground by the rotation of the discs. However, when further fine grinding is required, the distance between the two grinding discs needs to be made closer. During the grinding process, the rapid friction between the two discs causes their temperature to rise. This temperature increase leads to changes in the internal structure of the cement clinker, particularly the phase transformation of moisture or certain mineral components. Under high temperatures, the flowability of the cement clinker is affected, resulting in decreased grinding efficiency and accelerated equipment wear, shortening its service life. Therefore, existing technologies usually include a cooling mechanism to cool the grinding discs during the grinding process.

[0004] Existing cooling methods typically include water cooling and air cooling. Air cooling utilizes airflow to remove heat from the surface of the grinding disc without introducing additional moisture, thus avoiding the aforementioned problems. Furthermore, air cooling allows for rapid adjustment of cooling intensity, is easy to control, and does not cause secondary contamination to the grinding disc or clinker. It is also simple to maintain and has low costs. Therefore, air cooling is commonly used in existing technologies to cool the grinding disc. However, while air cooling can address the impact of temperature rise, the airflow also affects the flow path of the cement clinker between the grinding discs, leading to uneven clinker distribution and impacting grinding efficiency and product quality. Summary of the Invention

[0005] The present invention provides a grinding and processing equipment and process for cement clinker. The problem to be solved is that the existing air cooling method can solve the problem of the effect of temperature rise. However, as the air blows towards the grinding disc, it also blows towards the cement clinker between the grinding discs. At this time, the air force will interfere with the flow path of the cement clinker, resulting in uneven distribution of cement clinker, thereby affecting the grinding efficiency and product quality.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a grinding and processing equipment for cement clinker, comprising: a grinding cylinder, a feed pipe installed on the grinding cylinder, and the discharge end of the feed pipe extending into the grinding cylinder;

[0007] The grinding cylinder is equipped with an upper grinding disc and a lower grinding disc. The upper grinding disc is rotatably mounted at the bottom of the feed pipe, and the lower grinding disc is fixedly installed inside the grinding cylinder. The upper and lower grinding discs are aligned vertically. Cement clinker is conveyed between the upper and lower grinding discs through the feed pipe.

[0008] The grinding cylinder is equipped with a rotary drive mechanism, which is used to drive the upper grinding disc to rotate and grind cement clinker.

[0009] The grinding cylinder is equipped with a blower mechanism, which includes a fan. The output end of the fan extends into the feed pipe. The blower mechanism is used to blow air between the upper and lower grinding discs to cool them down. The feed pipe is equipped with a flow-dividing mechanism, which includes multiple flow-dividing plates arranged in a ring array on the inner wall of the feed pipe. A guide hood is fixedly installed between the multiple flow-dividing plates. The guide hood is used to evenly guide the air force between two adjacent flow-dividing plates and to evenly blow the air force between the upper and lower grinding discs.

[0010] In a preferred embodiment, an air guide pipe is installed at the air outlet of the blower. The air guide pipe is fixedly installed on the grinding cylinder, and the air outlet of the air guide pipe extends into the feed pipe and points towards the air guide shroud. An exhaust pipe is also provided on the grinding cylinder.

[0011] In a preferred embodiment, a material control mechanism is provided inside the feed pipe. The material control mechanism includes a material cylinder, which is fixedly installed inside the feed pipe. A guide plate is rotatably provided inside the material cylinder, and a guide groove is provided on the guide plate. The material cylinder has a feed inlet and a discharge outlet, and the guide plate is located between the feed inlet and the discharge outlet.

[0012] In a preferred embodiment, a grinding compensation mechanism is provided inside the grinding cylinder. The grinding compensation mechanism includes an upper compensation component and a lower compensation component. The upper compensation component includes an upper grinding ring that can move linearly and rotate. The upper compensation component is used to drive the upper grinding ring to move until it is in contact with the edge of the upper grinding disk and moves synchronously with the upper grinding disk. The lower compensation component includes a lower grinding ring that can move linearly. The lower compensation component is used to drive the lower grinding ring to move until it is in contact with the edge of the lower grinding disk.

[0013] In a preferred embodiment, the upper compensation component includes a drive component 1, which is mounted on the grinding cylinder. A sliding ring is installed at the output end of the drive component 1. A fixed ring is fixedly disposed inside the grinding cylinder. The sliding ring is slidably disposed inside the fixed ring. A rotating ring is rotatably disposed inside the sliding ring. The rotating ring is fixedly connected to the upper grinding ring. A positioning block is fixedly disposed on the upper grinding ring, and the upper port diameter of the positioning block is larger than the lower port diameter. A positioning groove is opened on the upper grinding disc, and the positioning block is adapted to the positioning groove.

[0014] In a preferred embodiment, a ball bearing is movably disposed at the bottom of the positioning block, and an arc-shaped groove is formed on the inner wall of the bottom of the positioning groove, with the ball bearing fitting into the arc-shaped groove.

[0015] In a preferred embodiment, the lower compensation component includes a second drive element, which is mounted on the bottom inner wall of the grinding cylinder, and the lower grinding ring is mounted on the output end of the second drive element.

[0016] In a preferred embodiment, the rotary drive mechanism includes a power component, which is fixedly mounted on the grinding cylinder, and a drive gear is installed at the output end of the power component. A driven gear is fixedly arranged on the upper grinding disc, and the drive gear meshes with the driven gear.

[0017] In a preferred embodiment, the grinding cylinder is further provided with a discharge mechanism, which includes a guide plate fixedly disposed inside the grinding cylinder, and a discharge pipe is provided on one side of the grinding cylinder.

[0018] A processing technology for a cement clinker grinding and processing equipment includes the following steps:

[0019] Step 1: The cement clinker is fed into the feed pipe and the material control mechanism controls the intermittent feeding of the cement clinker.

[0020] Step 2: Cement clinker enters between the upper and lower grinding discs. The upper grinding disc is driven to rotate by the rotary drive mechanism to grind the cement clinker.

[0021] Step 3: The blower mechanism delivers air into the feed pipe and the air is distributed by the material control mechanism, so that the air is evenly distributed between the upper and lower grinding discs to cool them down.

[0022] Step 4: Drive the upper grinding ring to be installed on the upper grinding disk through the upper compensation component, so that the upper grinding ring rotates synchronously with the upper grinding disk. At the same time, drive the lower grinding ring to be installed on the lower grinding disk through the lower compensation component to extend the grinding path and compensate for the grinding time.

[0023] Step 5: The ground cement clinker is discharged through the discharge pipe.

[0024] The beneficial effects of this invention are as follows:

[0025] This invention, by setting up a blower mechanism and a flow-diverting mechanism, extends the air outlet of the blower into the feed pipe and guides and diverts the airflow, allowing the airflow to be evenly distributed between the upper and lower grinding discs for cooling. This reduces the interference of airflow on the flow path of cement clinker and solves the problem that airflow causes cement clinker to flow in all directions, resulting in uneven distribution of cement clinker and affecting grinding efficiency and product quality.

[0026] This invention, by setting up a grinding compensation mechanism, increases the diameter of the upper and lower grinding discs during air cooling via the blower mechanism, thereby extending the grinding path and ensuring the grinding effect. This solves the problem that the accelerated flow of cement clinker driven by the wind reduces the residence time of the cement clinker between the upper and lower grinding discs, resulting in insufficient grinding of the cement clinker and thus affecting the grinding effect.

Detailed Implementation

[0037] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0038] Refer to the instruction manual appendix Figures 1 to 4 A grinding and processing equipment for cement clinker includes: a grinding cylinder 1, a feed pipe 11 installed on the grinding cylinder 1, and the discharge end of the feed pipe 11 extending into the grinding cylinder 1;

[0039] The grinding cylinder 1 is provided with an upper grinding disc 2 and a lower grinding disc 3. The upper grinding disc 2 is rotatably set at the bottom end of the feed pipe 11, and the lower grinding disc 3 is fixedly installed in the grinding cylinder 1. The upper grinding disc 2 and the lower grinding disc 3 are aligned in the vertical direction. Cement clinker is conveyed to the space between the upper grinding disc 2 and the lower grinding disc 3 through the feed pipe 11.

[0040] The grinding cylinder 1 is equipped with a rotary drive mechanism 4, which is used to drive the upper grinding disc 2 to rotate and grind cement clinker.

[0041] A blower mechanism 5 is provided on the grinding cylinder 1. The blower mechanism 5 includes a fan 51. The output end of the fan 51 extends into the feed pipe 11. The blower mechanism 5 is used to blow air between the upper grinding disc 2 and the lower grinding disc 3 to cool them down. A flow-dividing mechanism 6 is provided inside the feed pipe 11. The flow-dividing mechanism 6 includes multiple flow-dividing plates 61 arranged in a ring array on the inner wall of the feed pipe 11. A guide hood 62 is fixedly provided between the multiple flow-dividing plates 61. The guide hood 62 is used to evenly guide the air force between two adjacent flow-dividing plates 61 and guide the air force to blow evenly between the upper grinding disc 2 and the lower grinding disc 3.

[0042] It should be noted that both the upper grinding disc 2 and the lower grinding disc 3 are provided with grinding teeth, and there are multiple grinding teeth, which are evenly distributed in the circumferential direction of the upper grinding disc 2 and the lower grinding disc 3.

[0043] The specific implementation scenario is as follows: First, cement clinker is fed into the feed pipe 11, allowing it to enter the space between the upper grinding disc 2 and the lower grinding disc 3. Simultaneously, the upper grinding disc 2 is rotated by the rotary drive mechanism 4 to grind the cement clinker that has entered the space between the upper grinding disc 2 and the lower grinding disc 3. At the same time, the blower 51 blows air into the feed pipe 11, and the air force is diverted by the air guide 62 and the diverter plate 61, so that the air force can be evenly distributed between the upper grinding disc 2 and the lower grinding disc 3 after diversion. By guiding and diverting the air force, the interference of the air force on the flow path of the cement clinker can be reduced, solving the problem that the air force will cause the cement clinker to flow in all directions, resulting in uneven distribution of cement clinker, which affects the grinding efficiency and product quality.

[0044] It should also be noted that the diversion mechanism 6, which is formed by the diversion plate 61 and the air guide 62, can not only divert and guide the air force, but also divert and guide the cement clinker during feeding, so that the cement clinker can enter evenly between the upper grinding disc 2 and the lower grinding disc 3, and the cement clinker can be evenly distributed between the upper grinding disc 2 and the lower grinding disc 3, further ensuring its grinding efficiency and grinding quality.

[0045] Further, please refer to the appendix to the instruction manual. Figure 2 The air outlet of the blower 51 is equipped with an air guide pipe 52, which is fixedly installed on the grinding cylinder 1. The air outlet of the air guide pipe 52 extends into the feed pipe 11 and points towards the air guide cover 62. An exhaust pipe 53 is also provided on the grinding cylinder 1.

[0046] It should be noted that by setting the air guide pipe 52, the air can be easily delivered, and by setting the exhaust pipe 53, the air inside the grinding cylinder 1 can be easily discharged.

[0047] In the above technical solution, by setting the air guide pipe 52 to extend into the feed pipe 11, and by using the diverter plate 61 and the air guide hood 62 to guide the air force, the air force is evenly introduced between the upper grinding disc 2 and the lower grinding disc 3 to cool them down. However, if all the cement clinker to be ground is directly put into the feed pipe 11 during feeding, and the cement clinker is gradually fed along with the grinding process, the air outlet of the air guide pipe 52 is located inside the feed pipe 11. As a result, the accumulation of cement clinker in the feed pipe 11 will make it difficult for the air force to be delivered between the upper grinding disc 2 and the lower grinding disc 3. Therefore, the present invention also proposes a material control mechanism 7 to control the feeding of cement clinker to avoid the above problems.

[0048] For details, please refer to the instruction manual appendix. Figure 2 and Figure 5 The feed pipe 11 is equipped with a material control mechanism 7, which includes a material cylinder 71. The material cylinder 71 is fixedly installed inside the feed pipe 11. A guide plate 72 is rotatably arranged inside the material cylinder 71. A guide groove 721 is opened on the guide plate 72. The material cylinder 71 is provided with a feed inlet 711 and a discharge outlet 712. The guide plate 72 is located between the feed inlet 711 and the discharge outlet 712.

[0049] It should be noted that the guide plate 72 is driven to rotate by a motor. During feeding, cement clinker is first put into the feed pipe 11, and the guide plate 72 is driven to rotate by the motor. During the rotation of the guide plate 72, the feeding is intermittently controlled by the guide groove 721 opened on the guide plate 72 and the material cylinder 71. This can avoid the cement clinker from accumulating in the feed pipe 11 and affecting the air conveying problem.

[0050] In the above technical solution, by setting an air guide pipe 52 to extend into the feed pipe 11, and by using a diverter plate 61 and an air guide hood 62 to guide the air force, the air force is evenly distributed between the upper grinding disc 2 and the lower grinding disc 3 to cool them down. This cooling is achieved by delivering uniform air force. However, during the air delivery process, there is a problem that the air force can accelerate the flow of cement clinker. Even with the diverter plate 61 and air guide hood 62 reducing interference with the flow path of the cement clinker, this issue persists. However, the wind accelerates the flow of cement clinker, which reduces the residence time of cement clinker between the upper grinding disc 2 and the lower grinding disc 3. This results in the cement clinker not being fully ground, thus affecting the grinding effect and causing the product particle size to be uneven or not meet the expected fineness requirements. To address this, the present invention also provides a grinding compensation mechanism 8. By setting controllable upper grinding ring 815 and lower grinding ring 822, the diameter of the upper grinding disc 2 and the lower grinding disc 3 is increased when they are cooled by air blowing mechanism 5, so as to extend their grinding path and ensure their grinding effect.

[0051] For details, please refer to the instruction manual appendix. Figure 6 and Figure 7 The grinding cylinder 1 is provided with a grinding compensation mechanism 8, which includes an upper compensation component 81 and a lower compensation component 82. The upper compensation component 81 includes an upper grinding ring 815 that can move linearly and rotate. The upper compensation component 81 is used to drive the upper grinding ring 815 to move to fit with the edge of the upper grinding disk 2 and move synchronously with the upper grinding disk 2. The lower compensation component 82 includes a lower grinding ring 822 that can move linearly. The lower compensation component 82 is used to drive the lower grinding ring 822 to move to fit with the edge of the lower grinding disk 3.

[0052] It should be noted that when the upper grinding disc 2 and the lower grinding disc 3 are cooled by blowing air through the blower mechanism 5, the upper grinding ring 815 is moved and made to fit against the edge of the upper grinding disc 2, so that the upper grinding ring 815 is mounted on the upper grinding disc 2. At the same time, when the upper grinding disc 2 rotates, the lower grinding ring 822 can rotate synchronously with the upper grinding disc 2 and drive the lower grinding ring 822 to move, so that the lower grinding ring 822 fits against the edge of the lower grinding disc 3. This can extend the grinding path during air cooling and ensure the grinding effect.

[0053] It should also be noted that while increasing the diameter of the upper grinding disc 2 and the lower grinding disc 3 can extend the grinding path, directly increasing their diameter would cause the cement clinker to remain between the upper and lower grinding discs 2 and 3 for too long when the blower mechanism 5 is not in a blowing state, leading to over-grinding and affecting product particle size and quality. Therefore, if the diameter of the upper and lower grinding discs 2 and 3 is directly increased, the blower mechanism 5 needs to be set to a continuous blowing state. However, continuous blowing and cooling would result in excessively low temperatures, affecting the stability and efficiency of the grinding process and increasing energy consumption, which is not conducive to energy-saving production. Therefore, the above-mentioned method of extending the grinding path is the only option to solve the problem of the wind accelerating the flow of cement clinker, reducing the residence time of cement clinker between the upper and lower grinding discs 2 and 3, resulting in insufficient grinding of cement clinker and affecting the grinding effect. Alternatively, the blower mechanism 5 can be set to timed drive, and the blower mechanism 5 can be used to cool down the product at regular intervals.

[0054] For details, please refer to the instruction manual appendix. Figure 7 and Figure 8 The upper compensation component 81 includes a drive component 811, which is mounted on the grinding cylinder 1. A sliding ring 813 is installed at the output end of the drive component 811. A fixed ring 812 is fixedly installed inside the grinding cylinder 1. The sliding ring 813 is slidably installed inside the fixed ring 812. A rotating ring 814 is rotatably installed inside the sliding ring 813. The rotating ring 814 is fixedly connected to the upper grinding ring 815. A positioning block 816 is fixedly installed on the upper grinding ring 815, and the upper port diameter of the positioning block 816 is larger than the lower port diameter. A positioning groove 817 is opened on the upper grinding disc 2, and the positioning block 816 is adapted to the positioning groove 817.

[0055] It should be noted that the positioning block 816 is shaped like a truncated pyramid, and the driving component 811 is a cylinder. When the blowing mechanism 5 is used to blow air to cool down, the cylinder drives the sliding ring 813 to move, and drives the upper grinding ring 815 to move through the rotating ring 814 until the positioning block 816 contacts the upper surface of the upper grinding disc 2. At this time, since the upper grinding disc 2 is still rotating under the drive of the rotary driving mechanism 4, when the positioning block 816 is vertically aligned with the positioning groove 817, the cylinder drives the upper grinding ring 815 to move, which allows the positioning block 816 to extend into the positioning groove 817 until the positioning block 816 is fully inserted into the positioning groove 817. At this time, the upper grinding ring 815 can be driven to rotate synchronously under the rotation of the upper grinding disc 2.

[0056] Further, please refer to the appendix to the instruction manual. Figure 7 The bottom of the positioning block 816 is movably provided with a ball bearing 818, and the bottom inner wall of the positioning groove 817 is provided with an arc groove 819, which is adapted to the ball bearing 818 and the arc groove 819.

[0057] It should be noted that by setting a ball bearing 818 at the bottom of the positioning block 816, the ball bearing 818 can first contact the upper surface of the upper grinding disc 2 during the movement of the upper grinding ring 815. The setting of the ball bearing 818 can reduce the friction of the upper grinding disc 2 during its rotation, thereby solving the problem of contact friction between the positioning block 816 and the upper surface of the upper grinding disc 2, and reducing the problem of damage to the upper grinding disc 2.

[0058] For details, please refer to the instruction manual appendix. Figure 6 The lower compensation component 82 includes a second drive component 821, which is installed on the bottom inner wall of the grinding cylinder 1, and the lower grinding ring 822 is installed at the output end of the second drive component 821.

[0059] It should be noted that the driving component 821 is a cylinder, which drives the lower grinding ring 822 to move so that the lower grinding ring 822 can fit against the edge of the lower grinding disc 3.

[0060] It should also be noted that the upper compensation component 81 and the lower compensation component 82 are driven simultaneously, so that when the upper grinding ring 815 and the lower grinding ring 822 move to the predetermined position, the cement clinker can be ground between the upper grinding ring 815 and the lower grinding ring 822, thereby extending the grinding path and ensuring the grinding quality.

[0061] Further, please refer to the appendix to the instruction manual. Figure 2 and Figure 3The rotary drive mechanism 4 includes a power component 41, which is fixedly mounted on the grinding cylinder 1. A drive gear 42 is installed at the output end of the power component 41, and a driven gear 43 is fixedly mounted on the upper grinding disc 2. The drive gear 42 meshes with the driven gear 43.

[0062] It should be noted that the power component 41 is an electric motor, which drives the drive gear 42 to rotate, so that the drive gear 43 can rotate through the drive gear 42, and drive the upper grinding disc 2 to rotate, so as to perform the grinding operation.

[0063] Further, please refer to the appendix to the instruction manual. Figure 2 The grinding cylinder 1 is also provided with a discharge mechanism 9, which includes a guide plate 91. The guide plate 91 is fixedly installed inside the grinding cylinder 1, and a discharge pipe 92 is provided on one side of the grinding cylinder 1.

[0064] It should be noted that the guide plate 91 is inclined. The ground cement clinker is discharged from between the upper grinding disc 2 and the lower grinding disc 3 and falls onto the inclined guide plate 91, so that the ground cement clinker slides down the inclined surface of the guide plate 91 until it is discharged from the discharge pipe 92.

[0065] Refer to the instruction manual appendix Figure 9 A processing technology for a cement clinker grinding and processing equipment includes the following steps:

[0066] Step 1: Cement clinker is fed into the feed pipe 11 and the material control mechanism 7 controls the intermittent feeding of cement clinker.

[0067] Step 2: Cement clinker enters between the upper grinding disc 2 and the lower grinding disc 3. The upper grinding disc 2 is driven to rotate by the rotary drive mechanism 4 to grind the cement clinker.

[0068] Step 3: The blower mechanism 5 delivers air to the feed pipe 11 and the air is divided by the material control mechanism 7 so that the air is evenly distributed between the upper grinding disc 2 and the lower grinding disc 3 to cool down the upper grinding disc 2 and the lower grinding disc 3.

[0069] Step 4: Drive the upper grinding ring 815 to be installed on the upper grinding disk 2 by the upper compensation component 81, so that the upper grinding ring 815 rotates synchronously with the upper grinding disk 2. At the same time, drive the lower grinding ring 822 to be installed on the lower grinding disk 3 by the lower compensation component 82 to extend the grinding path and compensate for the grinding time.

[0070] Step 5: The ground cement clinker is discharged through discharge pipe 92.

[0071] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
