Description

Technical Field

[0001] The present invention belongs to the technical field of crushers, and particularly relates to an intelligent multi-cylinder cone crusher and a method thereof. Background Art

[0002] The multi-cylinder cone crusher is a typical crushing equipment for medium and fine crushing of hard materials. It adopts the "laminated crushing" principle to improve the primary crushing yield, with simpler and more convenient maintenance and lower operating costs. Measures such as separating the moving cone from the main shaft and fixing the main shaft, and only the moving cone making a swinging motion improve the structural strength.

[0003] In the 1850s, with the development of hydraulic technology, the cone crusher could adopt hydraulic adjustment of the discharge opening and achieve overload protection. This is the hydraulic cone crusher, which has a very wide application in many industries with its unique performance advantages. With the continuous development, improvement and refinement of the hydraulic cone crusher, it has reached the level of serialization, standardization and normalization. The high-performance cone crusher has excellent performance and can meet the technological requirements of "more crushing and less grinding".

[0004] Due to its special structure, small volume, large installed power, high speed, high working efficiency, laminated crushing, high finished product quality and stable product particle size, the multi-cylinder cone crusher is widely used in the crushing operations of ores and rocks.

[0005] The crushing principle of the multi-cylinder hydraulic cone crusher is as follows: The working components of the multi-cylinder hydraulic cone crusher consist of two cones - the moving cone and the fixed cone. During operation, the motor drives the eccentric assembly to rotate through the pulley, transmission shaft, pinion and gear. The eccentric assembly drives the moving cone to make a swinging motion along the inner surface of the fixed cone. Near the fixed cone, the material is crushed by the extrusion and bending of the moving cone. Far from the fixed cone, the crushed material falls from the bottom of the cone due to gravity. The entire crushing and discharging process proceeds continuously and sequentially along the inner surface of the fixed cone. The release oil cylinder part consists of multiple release oil cylinders, multiple accumulators and connecting pipelines. The release oil cylinder mainly plays the role of over-iron protection and cavity cleaning, and is used to absorb and buffer the impact phenomenon of the adjusting ring jumping caused by a small number of hard materials during normal crushing.

[0006] With the continuous improvement of the requirements for energy conservation and environmental protection, users' requirements for crushing equipment are also increasing. The rapid development of information technology promotes the intelligent transformation of products. However, the existing crushing products have a low degree of intelligence, and each crushing equipment manufacturer is actively promoting the intelligence of products. Summary of the Invention

[0012] Furthermore, a frame is provided inside the frame assembly, frame ribs are provided inside the frame, horizontal holes are provided on the frame assembly, a main shaft is provided inside the frame ribs, a rib guard plate is installed on the top of the frame ribs, a counterweight guard is provided on the periphery of the top of the frame ribs close to the main shaft, and the counterweight guard is provided with an ash leakage trough; A horizontal shaft assembly is provided on one side of the lower part of the main machine, a horizontal shaft frame is provided on the horizontal shaft assembly, and a shaft frame guard plate is provided on the horizontal shaft frame; a release cylinder connector and a connecting pin are provided on the release cylinder, and the connecting pin is provided with a fracture neck.

[0013] Furthermore, an intelligent multi-cylinder cone crusher and its method, for the described intelligent multi-cylinder cone crusher, include the following steps: Step S1: By controlling the telescoping of the adjusting cylinder, the motor assembly slides on the motor support frame to adjust the tension of the drive V-belt; Step S2: After the drive V-belt and the motor assembly are adjusted, the oil is pumped out by the lubricating oil pump and sequentially input into the first oil collector, the filtering device, and the heat dissipation device and then into the second oil collector, and then the second oil collector provides lubrication and heat dissipation effects for the main machine; the grease in the grease bucket is added to the oil storage chamber of the electric grease pump by hand pressure through the oil pipe, and the grease in the oil storage chamber is pumped to the main machine through the oil delivery pipe, and the addition of grease and lubricating oil will be automatically controlled to ensure the normal operation and maintenance of the main machine; Step S3: After the grease and lubricating oil are added and the control system is fully turned on and prompts permission to feed, start feeding, crush the materials input into the main machine, and then discharge the crushed materials. When the iron block enters the crushing chamber of the main machine and causes overload, the adjusting ring will jump, and the vibration sensor located on the adjusting ring will transmit the vibration of the adjusting ring to the control system. When the data received by the control system exceeds the set value, the electro-hydraulic overflow valve of the release cylinder at the corresponding position is triggered to reduce the release pressure. The crushing force at the corresponding position of the adjusting ring is higher than the release pressure, so the adjusting ring is lifted, and the discharge port of the main machine is enlarged to discharge the overload materials; Step S4: Scan the crushed materials through a ring scanner and transmit the scanned image to the control system. The control system identifies and processes the scanned image to obtain the product particle size composition, compares the product particle size with the set finished product particle size, and analyzes the comparison result to start adjusting the discharge port of the main machine; Step S5: Detect the oil fluid of the main machine through the sensor module, and summarize the data detected by the sensor module through the data acquisition device and transmit it to the control system. The control system calculates the pollution degree of the oil fluid to judge whether the oil fluid of the main machine can continue to be used. When the use conditions are not met, a prompt is issued that the lubricating oil does not meet the starting conditions, and the lubricating oil needs to be replaced.

[0014] Further, in step S1, adjusting the tension of the drive V-belt, the specific process is as follows: Set the pre-tightening force of the drive V-belt to P1 through the control system, and adjust the pressure of the adjusting cylinder drive motor assembly to P2. When the adjusting cylinder pressure is P = P1 + P2, it means that the drive V-belt meets the tension requirement. Monitor the displacements of each part of the motor assembly through displacement sensors arranged at different positions and feedback them to the control system. The control system drives the corresponding adjusting cylinder to move according to the feedback information of each displacement sensor. When the adjusting cylinder pressure is P = P1 + P2 and the displacements of each part of the motor assembly feedback by each displacement sensor are the same, the adjustment of the motor assembly is completed.

[0015] Further, when the pressure of the release cylinder exceeds the set pressure of the electro-hydraulic overflow valve, the electro-hydraulic overflow valve is turned on. At this time, the rodless chamber and the rod chamber of the release cylinder are connected, and the high-pressure oil in the rod chamber enters the rodless chamber, reducing the release pressure. The crushing force at the corresponding position of the adjusting ring is higher than the release pressure, so the adjusting ring is lifted, and the discharge port of the crusher is enlarged to discharge the overload materials. After the release, the control system detects that the pressure of the release cylinder is lower than the set value, and commands to start the hydraulic pump to pressurize the release cylinder to restore the release pressure; When the crushing pressure in the mainframe crushing chamber is higher than the pressure of the release oil cylinder, the oil in the rod chamber of the release oil cylinder will be pressed into the accumulator. The crushing force at the corresponding position of the adjusting ring is higher than the release pressure and it will rise. The discharge opening of the crusher will increase to discharge the overloaded material. After the release, the crushing pressure is less than the pressure of the release oil cylinder, and the oil pressed into the accumulator will return to the rod chamber of the release oil cylinder, and the active overload release system will return to its initial state.

[0016] Compared with the existing technologies, the present invention has the following beneficial effects: (1) The present invention has a protective effect on the mainframe through the active overload release system. When an iron block enters the crushing chamber and causes overload, it is detected by the vibration sensor and transmitted to the control system. Then, the electro-hydraulic overflow valve at the overloaded corresponding position is actuated by the control system to reduce the release pressure. The discharge opening of the mainframe is increased to discharge the overloaded material, preventing the crusher from being overloaded when an uncrushable object (such as an iron block) or excessive material enters the crushing chamber. In a continuous overload situation, it can cause damage to the components of the crusher (such as bearings, gears, crushing walls, etc.), and may even cause a failure of the entire equipment.

[0017] (2) When the pressure of the release oil cylinder exceeds the set pressure of the electro-hydraulic overflow valve in the present invention, the electro-hydraulic overflow valve is turned on. At this time, the rod chamber and the rodless chamber of the release oil cylinder are connected, and the high-pressure oil in the rod chamber enters the rodless chamber, reducing the release pressure. The crushing force at the corresponding position of the adjusting ring is higher than the release pressure and it will rise. The discharge opening of the crusher is increased to discharge the overloaded material. After the release, the control system detects that the pressure of the release oil cylinder is lower than the set value, and commands the hydraulic pump to start pressurizing the release oil cylinder to restore the release pressure, preventing damage to the release oil cylinder.

[0046] Among them, the main machine 101 includes a horizontal shaft assembly 10116, a shaft frame guard plate 10117, and a horizontal shaft frame 10118. A horizontal shaft assembly 10116 is provided on one side of the lower part of the main machine 101. A horizontal shaft frame 10118 is provided on the horizontal shaft assembly 10116. The shaft frame guard plate 10117 is arranged on the horizontal shaft frame 10118. The shaft frame guard plate 10117 is installed on the horizontal shaft frame 10118 to protect the horizontal shaft frame 10118 from being worn.

[0047] As Figure 18As shown in the figure, on the release oil cylinder 10101, there are a release oil cylinder connector 10119 and a connecting pin 10120. The release oil cylinder connector 10119 is connected by threads, which is convenient for replacement. The connecting pin 10120 is provided with a fracture neck 10121. When the crusher is overloaded and under impact load, both the release oil cylinder 10101 and the crusher will receive a particularly large impact force. In order to protect the crusher and the release oil cylinder 10101, a fracture neck 10121 is designed on the connecting pin 10120 of the release oil cylinder 10101. When the crusher is overloaded and under impact load, the fracture neck 10121 fractures preferentially, preventing more serious damage to the release oil cylinder 10101 and the crusher.

[0048] Among them, an intelligent multi-cylinder cone crusher and its method, for the described intelligent multi-cylinder cone crusher, includes the following steps: Step S1: By controlling the telescoping of the adjusting oil cylinder 10201, the sliding of the motor assembly 102 on the motor support frame 104 is adjusted to adjust the tension of the transmission V-belt 105. Step S2: After the transmission V-belt 105 and the motor assembly 102 are adjusted, the oil is pumped out through the lubricating oil pump 30106 and input into the first oil collector 301071, the filtering device 30108, and the heat dissipation device 30109 in sequence and enters the second oil collector 301072. Then, the second oil collector 301072 provides lubrication and heat dissipation effects for the main machine 101. The grease in the grease oil barrel 30114 is added to the oil storage chamber 30115 of the electric grease pump 30113 by hand pressure through the oil pipe 30116. The grease in the oil storage chamber 30115 is pumped to the main machine 101 through the oil delivery pipe 30117. The addition of grease and lubricating oil is automatically controlled to ensure the normal operation and maintenance of the main machine 1. Step S3: After the grease and lubricating oil are added, when the control system is fully turned on and prompts permission to feed, the feeding is started, the materials put into the main machine 101 are crushed, and then the crushed materials are discharged. When the crushing cavity of the main machine 101 enters an iron block and causes overload, the adjusting ring 10102 will jump. The vibration sensor 10103 located on the adjusting ring 10102 will transmit the vibration of the adjusting ring 10102 to the control system. When the data received by the control system exceeds the set value, the electro-hydraulic overflow valve 10107 of the release oil cylinder 10101 at the corresponding position is triggered to reduce the release pressure. The crushing force at the corresponding position of the adjusting ring 10102 is higher than the release pressure and it is lifted, and the discharge port of the main machine 101 is enlarged to discharge the overload materials. Step S4: The crushed materials are scanned by the ring scanner 10104, and the scanned images are transmitted to the control system. The control system identifies and processes the scanned images to obtain the product particle size composition, compares the product particle size with the set finished product particle size for analysis, and starts to adjust the size of the discharge port of the main machine 101 according to the comparison and analysis results. Step S5: The oil of the host 101 is detected by the sensor module 30104, and the data detected by the sensor module 30104 is summarized and transmitted to the control system through the data acquisition device 30105. The control system determines whether the oil of the host 101 can continue to be used by calculating the degree of contamination of the oil. When the use conditions are not met, a prompt is issued, indicating that the lubricating oil does not meet the startup conditions and the lubricating oil needs to be replaced.

[0049] The specific process of adjusting the tension of the transmission V-belt 105 in step S1 is as follows: The preload force of the transmission V-belt 105 is set to P1 through the control system, and the pressure of the adjusting cylinder 10201 driving the motor assembly 102 is set to P2 (the pressure of the adjusting cylinder 10201 when the transmission V-belt 105 is loose). When the pressure of the adjusting cylinder 10201 is P=P1+P2, it means that the transmission V-belt 105 meets the tensioning requirement. The displacement of each part of the motor assembly 102 is monitored by the displacement sensors 10203 arranged at different positions, and the displacement is fed back to the control system. The control system drives the corresponding adjusting cylinder 10201 to move according to the feedback information of each displacement sensor 10203. When the pressure of the adjusting cylinder 10201 is P=P1+P2 and the displacements of each part of the motor assembly 102 fed back by each displacement sensor 10203 are the same, the adjustment of the motor assembly 102 is completed.

[0050] Among them, when the pressure of the release cylinder 10101 exceeds the set pressure of the hydraulic control overflow valve 10106, the hydraulic control overflow valve 10106 is connected, and the rod chamber 1010101 and the rodless chamber 1010102 of the release cylinder 10101 are connected, and the high-pressure oil in the rod chamber 1010101 enters the rodless chamber 1010102, the release pressure is reduced, and the crushing force at the corresponding position of the adjustment ring 10102 is higher than the release pressure and is raised, and the discharge port of the crusher is enlarged to discharge the overloaded material. After the release, the control system detects that the pressure of the release cylinder 10101 is lower than the set value, and instructs the start of the hydraulic pump 30102 to pressurize the release cylinder 10101 to restore the release pressure; When the crushing pressure of the crushing chamber of the main engine 101 is higher than the pressure of the release cylinder 10101, the oil in the rod chamber 1010101 of the release cylinder 10101 will be pressed into the accumulator 10105, and the crushing force at the corresponding position of the adjustment ring 10102 is higher than the release pressure and raised, and the discharge port of the crusher is enlarged to discharge the overloaded material. After the release, the crushing pressure is lower than the pressure of the release cylinder 10101, and the oil pressed into the accumulator 10105 returns to the rod chamber 1010101 of the release cylinder 10101, and the system returns to its initial state.
