Description

Technical Field

[0001] This invention relates to the field of grinding technology, and in particular to an energy-saving grinding device for the production of chemical products. Background Technology

[0002] In the large-scale production of chemical products, various chemical raw materials need to be fed into grinding equipment for fine grinding. To improve production efficiency, the industry commonly adopts the following operating method: after pre-mixing the various chemical raw materials to be ground evenly, they are simultaneously fed into the grinding chamber for batch or continuous grinding operations, eliminating the need to feed and grind the various raw materials in batches sequentially.

[0003] In the implementation of the above-mentioned existing technology, due to the inherent differences in Mohs hardness, initial particle size, brittleness and grindability of different types of chemical raw materials, the problem of asynchronous grinding progress is very likely to occur during synchronous grinding. That is, the raw materials with better grindability have reached the target grinding particle size, while the raw materials with poor grindability have not yet been ground and refined. This problem will cause the qualified raw materials to remain in the grinding chamber for a long time, resulting in ineffective repeated grinding and directly causing an unnecessary increase in grinding energy consumption. On the other hand, the qualified raw materials will occupy a large amount of the effective grinding space in the grinding chamber, greatly reducing the utilization rate of the effective grinding area in the grinding chamber, hindering the full contact between the unqualified raw materials and the grinding media, and ultimately seriously affecting the grinding efficiency of the unqualified raw materials and the stability of the finished product quality.

Detailed Implementation

[0027] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0028] Please see Figures 1 to 9 The present invention provides an energy-saving grinding device for chemical product production, including a grinding chamber 1 and a grinding assembly; The grinding assembly includes a grinding body 2, a separation plate 3, a flow chamber 4, two grinding and filtering units, two collection units, and a collection chamber 5. The grinding body 2 is disposed inside the grinding chamber 1, the separation plate 3 is disposed below the grinding chamber 1, the flow chamber 4 is disposed below the separation plate 3, the two grinding and filtering units are symmetrically disposed on both sides of the flow chamber 4, the two collection units are respectively disposed below the corresponding grinding and filtering units, and the collection chamber 5 is located between the two collection units.

[0029] In this embodiment, the grinding chamber 1 provides a sealed grinding space for chemical raw materials, and the grinding body 2 is the core component for grinding the raw materials, capable of grinding and refining the mixed chemical raw materials fed into the grinding chamber 1. The separation plate 3 is a graded separation structure for the grinding raw materials, which can separate the qualified powder that has reached the target particle size from the large particles that have not been fully ground. The qualified powder can enter the flow chamber 4 below through the separation structure, while the large particles that have not reached the target size are trapped inside the grinding chamber 1, avoiding the qualified powder from continuously remaining in the grinding chamber and causing ineffective repeated grinding, thereby reducing unnecessary grinding energy consumption from the source. At the same time, it releases the effective grinding space in the grinding chamber 1, ensuring that the unqualified raw materials can fully contact the grinding body 2, improving grinding efficiency. The flow chamber 4 is for qualified powder. The system does not provide a transfer and conveying space, allowing the qualified powder inside to be transported to the grinding and filtering units on both sides for secondary fine filtration. The grinding and filtering units can perform secondary filtration and separation of trace amounts of non-compliant large particles mixed in the powder, further ensuring the particle size uniformity and quality stability of the finished powder. The collection unit can transport the non-compliant large particles separated by filtration to the collection chamber 5 for centralized collection, making it convenient for staff to put the non-compliant raw materials back into the grinding chamber 1 for secondary recycling and grinding, realizing full utilization of raw materials and avoiding waste. Finally, through the closed-loop process of grinding-separation-filtration-recycling grinding, the system achieves precise classification and separation of qualified powder and non-compliant raw materials, eliminates the repeated grinding of qualified powder, significantly reduces grinding energy consumption, and significantly improves grinding efficiency and finished product quality stability.

[0030] Furthermore, the grinding assembly also includes a grinding drive unit, which includes a support 6, a grinding lifting component 7, a lifting block 8, and a grinding rotating component 9. The support 6 is disposed above the grinding chamber 1, the grinding lifting component 7 is disposed on the support 6, the output end of the grinding lifting component 7 is fixedly connected to the lifting block 8, the grinding rotating component 9 is disposed inside the lifting block 8, the output end of the grinding rotating component 9 is fixedly connected to the grinding body 2, and the grinding body 2 is sleeved on the outside of the lifting block 8.

[0031] In this embodiment, the bracket 6 provides a stable installation support base for the entire grinding drive unit. The grinding lifting component 7 can drive the lifting block 8 to perform vertical lifting and lowering movements, thereby driving the grinding body 2 to lift and lower synchronously, accurately adjusting the distance between the grinding body 2 and the raw material layer in the grinding chamber 1, adapting to the operational needs of different feeding amounts and different grinding stages. At the same time, it can raise the height of the grinding body 2 when the raw material is separated and discharged, avoiding interference with the raw material discharge. The grinding rotation component 9 provides rotational driving power for the grinding operation of the grinding body 2, which can drive the grinding body 2 to rotate at high speed, efficiently grinding and refining the chemical raw materials in the grinding chamber 1. The lifting block 8 provides installation protection space for the grinding rotation component 9, and at the same time can form a limiting guide for the rotational movement of the grinding body 2, ensuring the stability of the grinding body 2 during high-speed rotation, avoiding problems such as shaking and deviation, and improving the stability and grinding accuracy of the grinding operation.

[0032] Furthermore, the grinding assembly also includes a separation unit, which includes an unfolding component 10, an unfolding plate 11, multiple columns 12, a support plate 13, and multiple blocking telescopic components 14. The unfolding component 10 is disposed below the grinding chamber 1, and the output end of the unfolding component 10 is fixedly connected to the unfolding plate 11. The multiple blocking telescopic components 14 are sequentially disposed outside the unfolding plate 11, and the output ends of the multiple blocking telescopic components 14 are all fixedly connected to the support plate 13. The support plate 13 is provided with multiple columns 12, and the separation plate 3 has multiple separation holes 15. The multiple columns 12 all penetrate the unfolding plate 11 and are respectively adapted to the corresponding separation holes 15.

[0033] In this embodiment, the separation unit can automatically control the opening and closing of the separation holes 15 on the separation plate 3, adapting to the needs of two different working conditions: grinding and separation / unloading. The unfolding component 10 can drive the unfolding plate 11 to perform horizontal unfolding and closing movements, causing multiple columns 12 to align with the separation holes 15, providing a basis for sealing and opening the separation holes 15. The blocking telescopic component 14 can drive the support plate 13 to perform vertical lifting and lowering movements, thereby causing multiple columns 12 to rise and fall synchronously. During the grinding operation, the blocking telescopic component 14 drives the support plate 13 to rise. Multiple columns 12 are fully inserted into their corresponding separation holes 15, sealing the separation holes 15 to prevent raw materials from falling during grinding and ensuring the normal operation of the grinding process. When grinding is complete and separation is required, the blocking telescopic component 14 drives the support plate 13 to descend, causing the columns 12 to exit from the separation holes 15, opening the separation holes 15, and allowing the powder that meets the grinding standards to fall into the flow chamber 4 below, thus achieving graded separation of qualified powder and unqualified raw materials. The multiple columns 12 correspond one-to-one with the separation holes 15, enabling synchronous opening and closing control of all separation holes 15, ensuring precise on / off control and stable and reliable operation.

[0034] Furthermore, the grinding assembly also includes a flow unit, which includes a plurality of actuating components 16 and an actuating inclined plate 17. The plurality of actuating components 16 are sequentially arranged below the flow chamber 4, the actuating inclined plate 17 is slidably connected to the flow chamber 4, and the output end of the actuating component 16 is fixedly connected to the actuating inclined plate 17.

[0035] In this embodiment, the flow unit provides driving power for the powder conveying in the flow chamber 4, ensuring that the qualified powder falling into the flow chamber 4 flows smoothly to the grinding and filtering units on both sides, avoiding powder accumulation and caking in the flow chamber 4; the jacking inclined plate 17 provides an inclined flow bearing surface for the powder, which can use gravity to assist the powder to flow to both sides; multiple jacking components 16 can synchronously drive the jacking inclined plate 17 to perform high-frequency vertical reciprocating jacking, and the powder on the jacking inclined plate 17 becomes fluid through vibration, accelerating the powder to flow to the filtering channels on both sides, while avoiding powder adhesion to the surface of the jacking inclined plate 17, ensuring the smoothness and completeness of powder conveying, and preventing the problem of raw material residue.

[0036] Furthermore, the grinding and filtering unit includes a filter channel 18, a filter plate 19, a filter lifting component 20, an opening and closing plate 21, an opening and closing component 22, and a feeding auxiliary mechanism. The filter channel 18 is connected to one side of the flow chamber 4. The filter plate 19 is slidably connected to the filter channel 18. The filter lifting component 20 is disposed below the filter channel 18. The output end of the filter lifting component 20 is fixedly connected to the filter plate 19. The opening and closing plate 21 is rotatably connected to the filter channel 18. The opening and closing component 22 is disposed on one side of the opening and closing plate 21. The feeding auxiliary mechanism is disposed below the opening and closing plate 21.

[0037] In this embodiment, the filter channel 18 provides a conveying space for secondary powder filtration, receiving powder from the flow chamber 4 and guiding it through the filter plate 19 for secondary fine filtration. The filter plate 19 is the core component of the secondary filtration, capable of intercepting and filtering trace amounts of substandard large particles mixed in the powder, further improving the particle size uniformity of the finished powder. The filter lifting component 20 can drive the filter plate 19 to move vertically up and down, adjusting the filtration angle of the filter plate 19. Simultaneously, it can also adjust the filter plate 19 up and down after filtration to facilitate the interception of large particles. Material feeding; the opening and closing component 22 can drive the opening and closing plate 21 to rotate and open and close. During the filtration operation, the opening and closing plate 21 is closed, blocking the feeding port of the filter channel 18, ensuring that the powder flows completely through the filter plate 19 to complete the filtration; after filtration, the opening and closing component 22 drives the opening and closing plate 21 to open, so that the large particles of raw material intercepted on the filter plate 19 can fall into the collection unit below through the feeding port; the feeding auxiliary mechanism can be activated after filtration to assist the smooth feeding of large particles of raw material, avoid the material from adhering, getting stuck, or blocking in the feeding area of ​​the opening and closing plate 21, and ensure the completeness and smoothness of feeding.

[0038] Furthermore, the grinding and filtering unit also includes a collection pump 23 and a collection box 24. The collection pump 23 is disposed at one end of the filter channel 18, and the collection box 24 is disposed at the output end of the filter plate 19.

[0039] In this embodiment, the collecting pump 23 provides negative pressure driving force for the flow of powder in the filter channel 18, which can accelerate the flow of powder in the flow chamber 4 into the filter channel 18, and at the same time guide the powder to flow quickly through the filter plate 19 to complete the filtration, thereby improving the efficiency of the filtration operation. The qualified finished powder after filtration by the filter plate 19 is transported to the collecting box 24 for centralized collection under the drive of the collecting pump 23, thus completing the storage of the finished powder. The collecting box 24 adopts a detachable design, which makes it convenient for the staff to take out the finished powder for subsequent chemical production processes, making the operation convenient and efficient.

[0040] Furthermore, the feeding auxiliary mechanism includes an auxiliary inclined plate 25, a plurality of protrusions 26 and a plurality of protruding components 27. The auxiliary inclined plate 25 is slidably connected to the filter channel 18. The plurality of protruding components 27 are sequentially arranged inside the auxiliary inclined plate 25. The output ends of the plurality of protruding components 27 are respectively fixedly connected to the corresponding protrusions 26. The protrusions 26 are slidably connected to the auxiliary inclined plate 25.

[0041] In this embodiment, the auxiliary inclined plate 25 provides feeding drive and anti-clogging function for the large particles separated by filtration. During the filtration process, the auxiliary inclined plate 25 retracts to the side storage position of the filtration channel 18 to avoid interfering with the flow of powder filtration. When filtration is completed and large particles need to be fed, the auxiliary inclined plate 25 slides into the filtration channel 18, moves to the feeding area side of the opening and closing plate 21, and performs high-frequency continuous up-and-down reciprocating movement. At the same time, the multiple protruding parts 27 inside the auxiliary inclined plate 25 synchronously drive the corresponding protrusions 26 to perform high-frequency reciprocating telescopic movement. Through the up-and-down movement of the auxiliary inclined plate 25 and the telescopic pushing of the protrusions 26, the large particles are continuously driven to flow in the feeding area of ​​the opening and closing plate 21, completely eliminating the problems of material accumulation, bridging, and jamming. This fundamentally avoids the situation where large particles are blocked in the feeding area of ​​the opening and closing plate 21 and cannot be fed, ensuring that the large particles can fall smoothly and completely into the collection unit below without material residue or feeding interruption.

[0042] Furthermore, the feeding auxiliary mechanism also includes two sealing blocks 28 and two springs 29. The filter channel 18 has two grooves 30. The two sealing blocks 28 are slidably connected to the corresponding grooves 30 respectively. The two ends of the two springs 29 are movably connected to the inner walls of the corresponding sealing blocks 28 and the grooves 30 respectively. The two sealing blocks 28 are located on both sides of the auxiliary inclined plate 25.

[0043] In this embodiment, the two sealing blocks 28 can form an adaptive seal to block the gap between the auxiliary inclined plate 25 and the inner wall of the filter channel 18. During the filtration process, the auxiliary inclined plate 25 is in the side storage position, and the two sealing blocks 28 are tightly fitted under the rebound action of the spring 29, sealing the installation gap of the auxiliary inclined plate 25, preventing powder from leaking from the gap during filtration, and ensuring that all powder can flow through the filter plate 19 to complete filtration; when filtration is completed and the auxiliary inclined plate 25 slides into the unloading position in the filter channel 18, the side of the auxiliary inclined plate 25... The sealing block 28 on the corresponding side can be pushed to compress the spring 29 and retract into the groove 30, while the sealing block 28 on the other side extends under the rebound action of the spring 29, always closely fitting the side of the auxiliary inclined plate 25, ensuring that the two sides of the auxiliary inclined plate 25 remain completely sealed during the up-and-down reciprocating movement, and preventing powder leakage; the groove 30 provides installation and operating space for the sealing block 28 and the spring 29, and the spring 29 can provide a continuous rebound pushing force for the sealing block 28, ensuring the stability and adaptability of the seal.

[0044] Furthermore, the collection unit includes a discharge channel 31 and a collection ramp 32. The discharge channel 31 is located below the opening and closing plate 21, and the collection ramp 32 is located below the collection box 24 and the discharge channel 31.

[0045] In this embodiment, the feeding channel 31 provides a guiding channel for the feeding of large-particle raw materials. It can receive substandard large-particle raw materials falling from the filtration channel and guide the raw materials to the collection inclined plate 32. The collection inclined plate 32 is an inclined guiding structure that can smoothly guide and transport the large-particle raw materials falling from the feeding channel 31 and the residual raw materials falling from the filter plate 19 to the middle collection chamber 5, realizing the centralized collection of substandard raw materials. This makes it convenient for staff to put the substandard raw materials back into the grinding chamber 1 for secondary recycling and grinding without the need for manual cleaning of the filter units on both sides, which greatly reduces the difficulty of operating the equipment and the intensity of manual labor.

[0046] Furthermore, the grinding assembly also includes a control module 33 and an operation panel 34, which are sequentially arranged on one side of the flow chamber 4.

[0047] In this embodiment, the operation panel 34 provides a human-machine interface for on-site personnel, allowing them to input grinding parameters, start and stop the equipment, set separation and filtration cycles, and adjust the operating parameters of each driving component. It also displays real-time data such as the device's operating status, grinding progress, finished product collection volume, and raw material inventory in the collection bin, making operation convenient and intuitive. The control module 33 is the core control hub of the device, receiving control commands from the operation panel 34 and detection signals from various sensors. Simultaneously, it sends precise control signals to all executing components, including the grinding lifting component 7, grinding rotating component 9, unfolding component 10, blocking telescopic component 14, and jacking component 16, achieving automated intelligent control of the entire process of raw material grinding, grading and separation, secondary filtration, and raw material collection. The automated control sequence is as follows: after completing the grinding operation according to preset parameters, the control module 33 automatically starts the separation unit to open the separation hole 15 to complete raw material grading, and simultaneously starts the jacking component 16 of the flow unit to drive the jacking inclined plate 17. Vibration feeding automatically starts the filtration, unloading and collection process after feeding is completed, realizing closed-loop automated control of the entire process of grinding-separation-filtration-circulating grinding; no manual intervention is required, which greatly improves the automation level and operational stability of the equipment. At the same time, the operating parameters can be flexibly adjusted according to the type and grindability of chemical raw materials to adapt to the grinding needs of different types of chemical raw materials.

[0048] When using the energy-saving grinding device for chemical product production according to this embodiment, the operator puts the mixed chemical raw materials to be ground into the grinding chamber 1, starts the device through the operation panel 34, inputs the corresponding grinding process parameters, and the control module 33 controls the blocking telescopic component 14 to start, driving the support plate 13 to lift multiple columns 12, so that the columns 12 are completely inserted into the separation holes 15 of the separation plate 3, sealing the separation holes 15; then the grinding lifting component 7 starts, driving the lifting block 8 to lower the grinding body 2 to the preset grinding height, and the grinding rotating component 9 starts, driving the grinding body 2 to rotate at high speed, grinding the chemical raw materials in the grinding chamber 1. Grinding and refining process: After the preset grinding time is reached, the grinding rotating component 9 stops driving the grinding body 2 to rotate, the grinding lifting component 7 drives the grinding body 2 to rise to the preset height, and the blocking telescopic component 14 drives the support plate 13 to lower the column 12, causing the column 12 to exit from the separation hole 15, opening the separation hole 15. The ground powder material that meets the standard falls into the flow chamber 4 below under the action of gravity through the separation hole 15. The large particles of material that are not completely ground are intercepted by the separation plate 3 inside the grinding chamber 1, completing the first classification and separation of the qualified powder and the unqualified material. The qualified powder falling into the flow chamber 4 falls onto the top inclined plate 17, and multiple top moving components 16 are activated to drive the top inclined plate 17 to move. High-frequency vertical vibration accelerates the flow of powder into the filter channels 18 on both sides. Simultaneously, the collection pump 23 starts, generating negative pressure suction to guide the powder in the flow chamber 4 quickly into the filter channel 18. As the powder flows through the filter plate 19, the filter plate 19 intercepts and filters out trace amounts of non-compliant large particles mixed in with the powder, completing secondary fine filtration. The filtered, compliant finished powder is then transported to the collection box 24 for centralized collection under the drive of the collection pump 23. After the preset amount of powder has been filtered, the collection pump 23 stops operating, the opening and closing component 22 drives the opening and closing plate 21 to rotate and open, and the filter lifting component 20 drives the filter plate 19 to vibrate and lift, causing the large particles intercepted on the filter plate 19 to be discharged onto the opening and closing plate 21. The feeding area moves; at the same time, the feeding auxiliary mechanism is activated, the auxiliary inclined plate 25 slides into the filter channel 18, moves to the feeding area side of the opening and closing plate 21 and moves up and down at high frequency. The protruding part 27 inside the auxiliary inclined plate 25 synchronously drives the protrusion 26 to perform high frequency telescopic movement. Through the up and down movement of the auxiliary inclined plate 25 and the pushing of the protrusion 26, the large particles of raw material in the feeding area are continuously flowed, avoiding the raw material from being blocked in the area of ​​the opening and closing plate 21 and unable to be fed. This ensures that the large particles of raw material fall smoothly through the feeding port of the opening and closing plate 21 into the feeding channel 31 below. The raw material falls onto the collecting inclined plate 32 through the feeding channel 31 and is guided by the collecting inclined plate 32 to be transported to the middle collecting bin 5 for centralized collection.Workers can periodically remove substandard large-particle raw materials from collection bin 5 and re-grind them into grinding bin 1. These re-grind materials will then be ground again together with the incompletely ground materials retained in grinding bin 1. If the raw materials still do not meet the standards after grinding, the above separation, filtration, collection, and secondary grinding operations will be repeated until all raw materials reach the target particle size. After all grinding operations are completed, all components of the device will be reset, and workers can then remove the qualified finished powder from collection bin 24 for subsequent chemical production processes.

[0049] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
