Description

Technical Field

[0001] This invention relates to the field of gypsum processing technology, and more specifically, to a gypsum crushing system and method for preparing vertical gypsum powder. Background Technology

[0002] In the preparation of vertical gypsum powder, the crushing of gypsum stone is a crucial initial step, and its crushing effect directly affects the quality and production efficiency of the subsequent gypsum powder. However, traditional gypsum stone crushing systems and methods have many problems that urgently need to be solved.

[0003] First, dust pollution is a significant problem. During gypsum stone crushing, the feed and discharge ports of the hammer crusher generate a large amount of dust. If this dust spreads into the working environment, it not only harms workers' health, potentially leading to occupational diseases such as pneumoconiosis with long-term exposure, but also causes serious environmental pollution, failing to meet current environmental protection requirements. Furthermore, traditional systems lack efficient dust recovery and utilization mechanisms, resulting in the waste of a large amount of usable dust and increasing production costs.

[0004] Secondly, crushing efficiency and quality need improvement. Under traditional crushing methods, the limited friction between gypsum particles makes it difficult to fully crush some gypsum during the crushing process, resulting in low crushing efficiency, uneven product particle size, and affecting the quality of the final gypsum powder. Furthermore, excessively high or low local dust concentrations can adversely affect internal components of the equipment, especially the hammers of hammer crushers. Excessive wear not only increases equipment maintenance costs but also reduces the equipment's lifespan and operational stability.

[0005] Furthermore, the level of automation is low. Traditional systems often require a lot of manual intervention in dust collection, filtration, spraying, and environmental parameter monitoring and adjustment. This not only increases labor costs but also makes the production process unstable due to human error, making it difficult to guarantee the consistency of production efficiency and product quality.

[0006] Furthermore, the material screening and recycling processes are not sufficiently robust. Traditional screening methods may not be able to accurately separate and recycle larger gypsum stone fragments, resulting in material waste and reduced resource utilization. Moreover, there are shortcomings in power recovery, failing to fully utilize the energy generated during equipment operation and increasing energy consumption. Summary of the Invention

[0007] In view of the problems existing in the prior art, the purpose of this invention is to provide a gypsum stone crushing system and method for vertical gypsum powder preparation, which solves the problems of serious dust pollution, low crushing efficiency and quality, low degree of automation and imperfect material screening and recovery in traditional gypsum stone crushing systems.

The liquid pump, miniature push rods, spray air pump, and flow control valve are all signal connected to the processor.

[0009] A method for using a gypsum stone crushing system for preparing vertical gypsum powder includes the following steps: S1. First, it is necessary to ensure that the vertical gypsum powder preparation production line is operating normally. This crushing system is only one link in the preparation process. The equipment needs to be maintained and prepared beforehand, such as filling the water tank with enough water and installing the dust sensor inside the hammer crusher. S2. After the equipment is in operation, use a shovel or dump truck to send the gypsum stone into the feeding hopper of the crushing workshop. The gypsum stone is then conveyed to the right side of the vibrating feeder to the feeding hopper of the hammer crusher. The hammer crusher is driven by an external high-power motor to rotate the flywheel on the rotor shaft, thereby driving the rotor shaft and multiple internal hammers to operate. S3. After the gypsum stone enters the casing of the hammer crusher, it is crushed by the hammer. With the help of the impact plate, the gypsum stone is crushed into small particles and discharged downward through the discharge chute into the screening chute in the bearing base. After passing through the screening plate, it is transported from the discharge chute to the bucket elevator and then to the gypsum stone block silo, and then fed into the vertical mill for grinding. If there are large-sized stones in the gypsum stone crushed by the hammer crusher during the above process, they cannot penetrate the screening plate and will be blocked by the screening plate and cannot be discharged through the discharge chute. The driven shaft supporting multiple sets of screening plates is equipped with a reducer and is connected to the rotor shaft in the hammer crusher through a synchronous pulley. The rotor shaft rotates quickly to drive the reducer, thereby driving the driven shaft to rotate, so that the larger-sized gypsum stone fragments are sent into the recycling tank for recycling by the counterclockwise rotation of the screening plate. S4. Dust is generated during the crushing of gypsum stone. The hammer crusher has two outlets: the top feed hopper and the bottom discharge chute. The dust will spread to both sides. The hammer crusher has dust sensors, humidity sensors and temperature sensors inside. The above sensors monitor the values ​​inside the machine casing in real time and transmit the signals to the processor. The processor obtains the values ​​and controls the dust collection component and dust ejection component to operate properly. S5. The processor controls the operation of the dust collection component. The collection air pump generates suction to create negative pressure inside the dust treatment box. At this time, the collection tank is kept sealed by the sealing partition, which causes the inlet collection pipe and the outlet collection pipe to generate suction. Dust generated inside the machine casing due to feeding or crushing diffuses to this position and enters the dust treatment box under suction. Due to the dust blocking net on the mounting frame, it is restricted to the right side of the dust filter component. Some dust is inside the collection tank and is limited by the sealing partition. The processor will intermittently control the drive motor to operate, so that multiple sealing partitions rotate at the same time to send the dust into the dust ejection component. During the above process, the processor will intermittently control the electromagnet in the dust filter assembly to operate intermittently. When the electromagnet operates, it generates magnetism to attract the metal plate mounted on the top of the mounting bracket, causing the metal plate to pull the mounting bracket and the dust barrier net downward. The spring begins to contract and produces the opposite effect. Then, the processor controls the electromagnet to be de-energized, and the mounting bracket will rebound vertically due to the inertia of the spring. This causes the dust attached to the dust barrier net to fall into the collection tank, avoiding blockage. S6. The processor controls the operation of the dust ejection assembly based on the values ​​returned by the dust sensor, temperature sensor, and humidity sensor. When the dust is sent into the ejection chamber through the sealed partition, it accumulates in the left part of the ejection chamber. If the returned value indicates that the humidity inside the crushing chamber is low or high, the processor controls the micro push rod to drive the guide block to move vertically to the relative position, so that the top or bottom channel of the baffle plate is exposed. When the ejection air pump ejects air through the booster pipe, the airflow carrying the dust flows through the top or bottom channel of the baffle plate after being restricted by the guide block. This allows for heating and drying or humidifying of the dust under different conditions. Subsequently, the dust passes through the ejection pipe to the inside of the diversion pipe. The flow control valve controls the flow nozzle to eject the treated dust into the crushing chamber, so that the dust assists in crushing and improves the crushing effect. At the same time, it improves the crushing environment and protects the internal components of the hammer crusher, such as the hammer head. S7. During operation, the entire system continuously performs operations such as dust collection, environmental parameter monitoring, dust treatment, and dust ejection. The control system dynamically adjusts the working status of each link based on the real-time monitored environmental parameters to ensure that parameters such as dust content, temperature, and humidity in the crushing chamber are always kept within the range most conducive to crushing, thereby achieving an efficient and stable crushing production process.

[0010] Compared with the prior art, the advantages of this invention are: (1) In this invention, the system is equipped with a high-efficiency dust collection component. Its collection air pump, feed inlet collection pipe and discharge outlet collection pipe collect dust from the feed inlet and outlet of the hammer crusher, effectively preventing dust diffusion, protecting workers' health and the environment. The dust barrier and the vibration mechanism driven by the electromagnet can prevent dust accumulation, maintain filtration efficiency and extend equipment life. The system's built-in dust, humidity, and temperature sensors monitor the environmental parameters of the crushing chamber in real time, automatically adjusting the dust ejection method and volume accordingly. A flow control valve ensures uniform dust distribution, which fills the gaps between gypsum particles, increases material friction, improves crushing efficiency, reduces the adverse effects of abnormal local dust concentrations on the equipment, protects internal components such as hammers, and reduces wear. The entire dust handling process is highly integrated and automated, reducing manual intervention, improving production efficiency and system reliability, and ensuring that the parameters within the crushing chamber are conducive to crushing.

[0011] (2) In the screening process of this invention, the screening trough is connected to the discharge trough of the hammer crusher, and the driven shaft and the rotor shaft are connected by synchronous pulley and synchronous belt. When the rotor shaft drives the reducer to work, it drives the driven shaft to rotate, thereby realizing power recovery. The screening plate can rotate the larger gypsum stone fragments that cannot be penetrated counterclockwise and send them into the recycling trough for recycling, thereby realizing the effective screening and recycling of materials.

[0020] The support base 1 has a screening trough 101 inside, which is connected to the discharge trough 202 at the bottom of the hammer crusher 2.

[0021] When using it, it is necessary to first ensure that the vertical gypsum powder preparation production line is operating normally. This crushing system is only one link in the preparation process. The equipment needs to be maintained and prepared beforehand, such as filling the water tank 50311 with enough water and installing the dust sensor 12 inside the hammer crusher 2. After the equipment is in operation, a shovel or dump truck is used to send gypsum stone into the feeding hopper of the crushing workshop. The gypsum stone is conveyed to the right side by the vibrating feeder 3 to the feeding hopper 201 of the hammer crusher 2. The hammer crusher 2 is driven by an external high-power motor to rotate the flywheel on the rotor shaft 203, thereby driving the rotor shaft 203 and multiple internal hammers 204 to operate. After entering the casing 200 of the hammer crusher 2, the gypsum stone is crushed by the hammer 204. With the help of the impact plate 205, the gypsum stone is crushed into small particles and discharged downward through the discharge chute 202 into the screening chute 101 in the bearing base 1. After passing through the screening plate 103, it is transported by the drop chute 105 to the bucket elevator 4 and then fed into the gypsum stone block hopper, and then fed into the vertical mill for grinding.

[0022] If there are large-sized stones in the gypsum stone crushed by the hammer crusher 2 during the above process, they cannot penetrate the screening plate 103 and will be blocked by the screening plate 103 and cannot be discharged through the discharge chute 105. The driven shaft 102 supporting multiple sets of screening plates 103 is equipped with a reducer 106 on the front and is connected to the rotor shaft 203 in the hammer crusher 2 through the synchronous wheel 107. The rotor shaft 203 rotates rapidly, driving the reducer 106 to work, thereby driving the driven shaft 102 to rotate, so that the larger-sized gypsum stone fragments are sent into the recycling tank 104 for recycling by the counterclockwise rotation of the screening plate 103.

[0023] Dust is generated during the crushing of gypsum stone. The hammer crusher 2 has two outlets: a top feed hopper 201 and a bottom discharge chute 202. The dust will spread to both sides. The hammer crusher 2 contains a dust sensor 12, a humidity sensor 13, and a temperature sensor 14. These sensors monitor the values ​​inside the casing 200 in real time and transmit the signals to the processor 11. The processor 11 obtains the values ​​and uses them to control the dust collection component 501 and the dust ejection component 503 to operate properly.

[0024] The processor 11 controls the operation of the dust collection assembly 501. The collecting air pump 5011 generates suction, creating a negative pressure inside the dust handling box 5. The collecting air pump 5011 discharges the airflow inside the dust handling box 5 to the outside through an external pipe or connects to a gas purification device. At this time, the collecting tank 5014 remains sealed due to the sealing partition 5016, thereby generating suction between the inlet collecting pipe 5012 and the outlet collecting pipe 5013. Dust generated inside the casing 200 due to feeding or crushing diffuses to the inlet collecting pipe 5012 and the outlet collecting pipe 5013. After reaching position 3, the dust enters the dust handling box 5 under suction. The dust inside the dust handling box 5 is restricted to the right side of the dust filter assembly 502 by the dust blocking net 5022 on the mounting frame 5021. Some of the dust is inside the collection tank 5014 and is limited by the sealing partition 5016. Then, the processor 11 will intermittently control the operation of the drive motor 5015. The output shaft of the drive motor 5015 drives multiple sealing partitions 5016 to rotate simultaneously, thereby sending the dust in the collection tank 5014 into the dust ejection assembly 503.

[0025] During the above process, the processor 11 intermittently controls the electromagnet 5025 inside the dust filter assembly 502 to operate intermittently. When the electromagnet 5025 operates, it generates magnetism, which attracts the metal plate 5024 mounted on the top of the mounting bracket 5021. This causes the metal plate 5024 to pull the mounting bracket 5021 and the dust barrier net 5022 downward. At this time, the spring 5023 begins to contract and generates an opposing force. Then, the processor 11 controls the electromagnet 5025 to be de-energized. The mounting bracket 5021, under the inertia of the spring 5023, reciprocates vertically. Through this reciprocating motion, the dust adhering to the dust barrier net 5022 falls into the collection tank 5014, preventing dust from accumulating on the dust barrier net 5022 and causing blockage.

[0026] The processor 11 controls the operation of the dust ejection assembly 503 based on the values ​​returned by the dust sensor 12, temperature sensor 14 and humidity sensor 13. When the dust is sent into the ejection chamber 5031 by the sealing partition 5016, it will accumulate in the left part of the ejection chamber 5031. If the returned value indicates that the humidity of the crushing chamber space inside the hammer crusher 2 is too high and too humid, the processor 11 controls the micro push rod 50310 to drive the guide block 5039 to move vertically downward to the relative position, so that the top channel of the baffle plate 5038 is exposed. At this time, the ejection air pump 5037 ejects airflow through the booster pipe 5036. The airflow carrying dust flows through the top channel of the baffle plate 5038 after being restricted by the guide block 5039. The dust is heated and dried by the heating plate 50314.

[0027] If the returned value indicates that the humidity inside the crushing chamber is too low and too dry, the processor 11 controls the micro push rod 50310 to drive the guide block 5039 to move vertically upward to the relative position, so that the bottom channel of the baffle plate 5038 is exposed. When the ejector pump 5037 ejects airflow through the booster pipe 5036, the airflow carrying dust flows through the bottom channel of the baffle plate 5038 after being restricted by the guide block 5039. At the same time, the liquid pump 50312 draws liquid from the water tank 50311 and delivers it to the atomizing nozzle 50313 through the pipeline. The atomizing nozzle 50313 atomizes the liquid and sprays it into the ejection chamber 5031 to achieve the humidification treatment of the dust.

[0028] After the above treatment, the dust enters the interior of the diversion pipe 5032 through the spray pipe 5034. Then, under the control of the flow control valve 5035, the flow nozzle 5033 evenly sprays the treated dust into the crushing chamber. After entering the crushing chamber, the sprayed dust fills the gaps between the gypsum particles, increasing the friction between the materials and making the gypsum easier to crush during the crushing process, thereby helping to improve the crushing effect. At the same time, the uniform distribution of dust improves the crushing environment and avoids the adverse effects of excessively high or low local dust concentration on the equipment. It also protects the internal components of the hammer crusher 2, such as the hammer head 204, reducing the wear and damage of the components.

[0029] The entire system continuously cycles through dust collection, environmental parameter monitoring, dust treatment, and dust ejection during operation. The control system dynamically adjusts the operating status of each stage based on real-time monitored environmental parameters, ensuring that parameters such as dust content, temperature, and humidity within the crushing chamber are always maintained within the range most conducive to crushing, thereby achieving an efficient and stable crushing production process.

[0030] In this invention, the system is equipped with a high-efficiency dust collection component 501, including a collection air pump 5011, a feed inlet collection pipe 5012, and a discharge outlet collection pipe 5013. These components effectively collect dust from the feed and discharge outlets of the hammer crusher 2, preventing dust from spreading into the working environment, protecting worker health, and reducing environmental pollution. Through the vibration mechanism driven by the dust barrier net 5022 and the electromagnet 5025, the system can effectively filter and clean the collected dust, preventing dust from accumulating on the filter net, maintaining filtration efficiency, and extending the service life of the equipment. The system's built-in dust sensor 12, humidity sensor 13, and temperature sensor 14 monitor the environmental parameters inside the crushing chamber in real time, ensuring that the dust treatment system can automatically adjust its working state according to the actual environmental conditions.

[0031] Simultaneously, based on the monitored environmental parameters, the system can automatically adjust the dust ejection method and precisely control the dust ejection amount through the flow control valve 5035 to ensure uniform dust distribution and improve the crushing efficiency of gypsum stone. By uniformly spraying the treated dust into the crushing chamber, it fills the gaps between gypsum stone particles, increases the friction between materials, and makes gypsum stone easier to crush during the crushing process, thereby improving crushing efficiency. The uniformly distributed dust reduces the adverse effects of excessively high or low local dust concentrations on the equipment and protects the internal components of the hammer crusher 2, such as the hammer head 204, reducing wear and damage to the components.

[0032] The entire system, from dust collection and filtration to spraying, and then to the monitoring and adjustment of environmental parameters, has achieved a high degree of integration and automation, reducing manual intervention and improving production efficiency and system reliability. The system can dynamically adjust the working status of each link according to the environmental parameters monitored in real time, ensuring that parameters such as dust content, temperature and humidity in the crushing chamber are always kept within the range most conducive to crushing, thereby achieving an efficient and stable crushing production process.

[0033] In the screening stage, the screening trough 101 is connected to the discharge trough 202 of the hammer crusher 2. The driven shaft 102 and the rotor shaft 203 are connected by a synchronous pulley 107 and a synchronous belt. The rotor shaft 203 drives the reducer 106 to work, which in turn drives the driven shaft 102 to rotate, thereby realizing power recovery. The screening plate 103 can rotate counterclockwise to send larger gypsum stone fragments that cannot be penetrated into the recycling trough 104 for recycling, thus realizing the effective screening and recycling of materials.

[0034] Please see Figure 2-4 Among them, the end of the inlet collection pipe 5012 located inside the collection cover 6 and the end of the outlet collection pipe 5013 located in the discharge trough 202 are both fixedly installed with crushed stone barrier nets 7.

[0035] In this invention, the crushed stone barrier 7 can prevent small-sized gypsum stones from entering the collection pipe and thus affecting the normal operation of the equipment.

[0036] Please see Figure 2-5 The spring 5023 has a guide shaft 8 inside, the bottom end of the guide shaft 8 is fixedly installed on the inner wall of the dust treatment box 5, and the mounting bracket 5021 is slidably connected to the guide shaft 8.

[0037] In this invention, the guide shaft 8 can restrict the vertical movement of the mounting bracket 5021, so that the mounting bracket 5021 always maintains stable vertical movement.

[0038] Please see Figure 2 , 3 4 and 6, wherein: an arc-shaped guide groove 9 is provided on the inner wall of the ejection cavity 5031, and the bottom end of the ejection pipe 5034 is located inside the arc-shaped guide groove 9.

[0039] In this invention, the arc-shaped guide groove 9 can guide the ejected airflow dust, allowing the airflow carrying dust to quickly enter the interior of the ejector pipe 5034, reducing energy consumption and increasing the impact force of the dust ejected into the crushing chamber.

[0040] Please see Figure 1-4 Among them, the inlet collection pipe 5012 is connected to the maintenance cover 10.

[0041] In this invention, the inspection cover 10 facilitates the maintenance of the pipeline by the user and avoids blockage.

[0042] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.

8. A vertical gypsum stone crushing method for preparing gypsum powder, which is suitable for the gypsum stone crushing system for preparing gypsum powder as claimed in any one of claims 1-7, and comprises the following steps: S1, first, water is filled into the water storage tank 50311, and the dust sensor 12 is installed in the hammer crusher 2 to complete the debugging of the equipment; S2, after the equipment is operated, the gypsum stone is sent into the feeding hopper of the crushing workshop by a shovel car or a self-unloading car, and the gypsum stone is conveyed to the feeding hopper 201 of the hammer crusher 2 through the vibrating feeder 3 to the right side, the hammer crusher 2 is driven by the flywheel rotating on the rotor shaft 203 driven by the external high-power motor, so as to drive the rotor shaft 203 and the plurality of hammer heads 204 inside to operate; S3, after the gypsum stone enters the inside of the shell 200 of the hammer crusher 2, the gypsum stone is broken by the hammer heads 204, and the gypsum stone is crushed into small particles by the counterattack plate 205, and then the small particles are discharged downward through the discharge chute 202 into the screening groove 101 in the bearing base 1, and then the small particles pass through the screening plates 103 downward and are conveyed to the gypsum stone block bin through the material falling groove 105 and the bucket elevator 4, and then the gypsum stone is fed into the vertical mill for grinding; If the gypsum stone crushed by the hammer crusher 2 has large-sized stones, the stones cannot penetrate the screening plates 103, and the stones are blocked by the screening plates 103 and cannot be discharged through the material falling groove 105, and the front face of the driven shaft 102 supporting the plurality of screening plates 103 is provided with the speed reducer 106 and is drivingly connected with the rotor shaft 203 in the hammer crusher 2 through the synchronous wheel 107, the speed reducer 106 is driven to work by the rapid rotation of the rotor shaft 203, so that the driven shaft 102 rotates, and the large-sized gypsum stone blocks are sent into the recycling groove 104 by the counterclockwise rotation of the screening plates 103 for recycling; S4. Dust is generated during the crushing of gypsum stone. The hammer crusher 2 has two outlets: the top feed hopper 201 and the bottom discharge chute 202. The dust will spread to both sides. The hammer crusher 2 has a dust sensor 12, a humidity sensor 13 and a temperature sensor 14 inside. The above sensors monitor the values ​​inside the casing 200 in real time and transmit the signals to the processor 11. The processor 11 obtains the values ​​and controls the dust collection component 501 and the dust ejection component 503 to operate properly. S5, the processor 11 controls the operation of the dust collection component 501. The collection air pump 5011 generates suction to create a negative pressure inside the dust treatment box 5. At this time, the collection tank 5014 is kept sealed by the sealing partition 5016, so that the inlet collection pipe 5012 and the outlet collection pipe 5013 generate suction. The dust generated inside the casing 200 due to feeding or crushing diffuses to this position and enters the interior of the dust treatment box 5 under the suction. Due to the function of the dust blocking net 5022 on the mounting frame 5021, it is restricted to the right side of the dust filter component 502. Some dust is inside the collection tank 5014 and is limited by the sealing partition 5016. The processor 11 will intermittently control the drive motor 5015 to operate, so that multiple sealing partitions 5016 rotate simultaneously to send the dust into the dust ejection component 503. During the above process, the processor 11 will intermittently control the electromagnet 5025 in the dust filter assembly 502 to operate intermittently. When the electromagnet 5025 operates, it generates magnetism to attract the metal plate 5024 mounted on the top of the mounting bracket 5021, causing the metal plate 5024 to pull the mounting bracket 5021 and the dust blocking net 5022 to move downward. The spring 5023 begins to contract and produces the opposite effect. Then, the processor 11 controls the electromagnet 5025 to be de-energized, and the inertia of the spring 5023 causes the mounting bracket 5021 to bounce back in the vertical direction, thereby causing the dust attached to the dust blocking net 5022 to fall into the collection tank 5014. S6. The processor 11 controls the operation of the dust ejection assembly 503 based on the values ​​returned by the dust sensor 12, temperature sensor 14 and humidity sensor 13. When the dust is sent into the ejection chamber 5031 by the sealing partition 5016, it accumulates in the left part of the ejection chamber 5031. If the returned value indicates that the humidity inside the crushing chamber is low or high, the processor 11 controls the micro push rod 50310 to drive the guide block 5039 to move vertically to the relative position so that the top or bottom channel of the baffle plate 5038 is exposed. When the ejection air pump 5037 ejects airflow through the booster pipe 5036, the airflow carrying dust flows through the top or bottom channel of the baffle plate 5038 after being restricted by the guide block 5039. This allows for heating and drying or humidifying of the dust under different conditions. Subsequently, the dust passes through the ejection pipe 5034 to the inside of the diversion pipe 5032. After being controlled by the flow control valve 5035, the flow nozzle 5033 ejects the treated dust into the crushing chamber.
