Description

Technical Field

[0001] The utility model relates to the technical field of multi-cylinder cone crushers, in particular to a control device for a multi-cylinder cone crusher. Background Art

[0002] The remarkable feature of a multi-cylinder cone crusher is that it uses multiple hydraulic cylinders to drive and control the movement of the crushing cone. The multiple hydraulic cylinders provide a powerful crushing force, enabling the machine to have higher efficiency and a larger crushing ratio when processing hard materials, achieving higher crushing efficiency and production capacity. In addition, the arrangement of multiple hydraulic cylinders also achieves a more uniform crushing effect, ensuring that the materials are evenly and finely crushed in the crushing chamber and improving the product quality.

[0004] In addition, the main shaft motor of a multi-cylinder cone crusher is usually directly driven at full voltage. This driving method has the following impacts on a multi-cylinder cone crusher: a large starting current and mechanical impact force will be generated instantaneously during driving, which will not only damage the transmission system and crushing components, but also the large current generated will impact the power grid, causing voltage fluctuations in the power grid and even affecting the normal operation of other electrical equipment.

[0027] The multi-cylinder cone crusher 1 includes a main motor, a soft start module, a locking cylinder, a safety cylinder, a discharge port adjustment mechanism and a first sensor module. The soft start module is respectively connected to the controller 2 and a three-phase power supply, and the output end of the soft start module is connected to the main motor. The locking cylinder, the safety cylinder and the discharge port adjustment mechanism are all connected to the output end of the controller 2. The first sensor module is used to detect the real-time temperature of the motor bearing;

[0028] The locking cylinder is an important part of the cone crusher, which is used to lock the lower cone and the upper cone of the crusher together to ensure stability during operation. The safety cylinder is used to remove the faulty objects in the crushing chamber. When an unbreakable object (such as an iron block, etc.) enters the crushing chamber or a momentary jam occurs, the safety cylinder can jack up the support sleeve and the fixed cone part by releasing the hydraulic cylinder, thereby automatically removing the faulty objects in the crushing chamber and improving reliability. The discharge port adjustment mechanism is used to control the lifting movement of the adjusting sleeve in the support sleeve, thereby causing the discharge port to increase or decrease.

[0029] The oil thinning station 3 includes an oil pump, an electric heater, a refrigerator and a second sensor module. The control ends of the oil pump, the electric heater and the refrigerator are all connected to the output end of the controller 2. The second sensor module is used to detect the oil level in the oil thinning tank, the oil return flow rate, the temperature of the oil thinning tank, the inlet oil pressure, the inlet oil flow rate, the inlet oil temperature and the oil return temperature. The oil pump in the oil thinning station 3 is responsible for pumping the lubricating oil out of the oil tank and delivering it to each part of the cone crusher that needs lubrication and cooling, realizing the circulation of the lubricating oil between the oil thinning station 3 and the multi-cylinder cone crusher 1, ensuring the normal operation of the multi-cylinder cone crusher 1 and extending its service life. The electric heater is used to heat the lubricating oil or hydraulic oil to ensure that the oil can still maintain good fluidity in a low-temperature environment. The refrigerator is used to cool the lubricating oil returned to the oil thinning station 3 to prevent equipment failures and performance degradation caused by overheating of the lubricating oil.

[0030] The high-pressure station 4 includes a high-pressure pump and a third sensor module. The control end of the high-pressure pump is connected to the output end of the controller 2. The third sensor module is used to detect the oil pressure of the high-pressure station 4, the oil pressure of the locking cylinder, the oil pressure of the safety cylinder and the opening size of the discharge port. The first sensor module, the second sensor module and the third sensor module are all connected to the input end of the controller 2. The high-pressure pump is used to provide hydraulic oil for components such as the locking cylinder, the safety cylinder and the discharge port adjustment mechanism.

[0031] By setting the controller 2 to automatically control the actions of the locking cylinder, safety cylinder, and discharge port adjustment mechanism, and through the first, second, and third sensor modules, the key parameters of the multi-cylinder cone crusher 1, thin oil station 3, and high-pressure station 4 are monitored in real time, facilitating the operator to timely obtain the working status of the multi-cylinder cone crusher 1, thin oil station 3, and high-pressure station 4, promptly eliminate equipment failures, reduce downtime, and extend the service life of the device.

[0032] Preferably, the first sensor module includes a first motor bearing temperature sensor and a second motor bearing temperature sensor. By monitoring the temperature change of the main motor bearing through the first motor bearing temperature sensor and the second motor bearing temperature sensor, it is convenient to obtain the operating status of the main motor. When abnormalities occur, lubrication problems, overload operation, or other potential faults can be promptly detected, extending the service life of the main motor.

[0033] Preferably, the second sensor module includes an oil level detection sensor, a return oil flowmeter, a thin oil tank temperature sensor, an inlet oil pressure sensor, an inlet oil flowmeter, an inlet oil temperature sensor, and a return oil temperature sensor. The oil level detection sensor is used to monitor the oil level in the thin oil tank in real time to avoid failures caused by insufficient oil volume. The return oil flowmeter and the inlet oil flowmeter are used to monitor the flow of return oil and inlet oil. According to the return oil flow and inlet oil flow, it can be judged whether the lubrication system is circulating normally, whether the efficiency of the lubrication system meets the requirements, and whether there are problems such as leakage. The thin oil tank temperature sensor is used to detect the oil temperature in the thin oil tank to ensure that the lubricating oil works within an appropriate temperature range and avoid affecting the lubrication effect and equipment performance due to too high or too low oil temperature. The inlet oil pressure sensor is used to monitor the pressure of the inlet oil pipeline to ensure that the lubricating oil can smoothly enter the parts that need to be lubricated. The inlet oil temperature sensor and the return oil temperature sensor are respectively used to detect the oil temperature of the lubrication system inlet oil of the multi-cylinder cone crusher 1 and the oil temperature of the return oil to the thin oil station 3, facilitating the discovery of abnormal oil temperature states and preventing equipment damage caused by abnormal oil temperature.

[0034] Preferably, the third sensor module includes a high-pressure station 4 oil pressure sensor, a locking cylinder pressure sensor, a safety cylinder pressure sensor, and a discharge port detection sensor. The high-pressure station 4 oil pressure sensor is used to monitor the oil pressure in the high-pressure station 4 in real time to ensure that the working pressure of the high-pressure hydraulic system is within the normal range. The locking cylinder pressure sensor is used to detect the oil pressure in the locking cylinder to ensure that the locking cylinder can firmly lock the key components of the crusher and prevent them from loosening during operation. The safety cylinder pressure sensor is used to monitor the pressure in the safety cylinder to ensure that when the crusher encounters hard materials or abnormal conditions, the safety cylinder can quickly respond and release pressure to protect the equipment from damage. The discharge port detection sensor is used to detect the size and status of the discharge port to ensure that the crushed materials can be discharged smoothly.

[0035] Preferably, the high-pressure station 4 further includes a locking cylinder pressurizing solenoid valve, a locking cylinder pressure relief solenoid valve, a discharge port enlarging solenoid valve, a discharge port reducing solenoid valve, a safety cylinder rising solenoid valve, and a safety cylinder falling solenoid valve. The locking cylinder pressurizing solenoid valve, the locking cylinder pressure relief solenoid valve, the discharge port enlarging solenoid valve, the discharge port reducing solenoid valve, the safety cylinder rising solenoid valve, and the safety cylinder falling solenoid valve are all connected to the output end of the controller 2. Through the locking cylinder pressurizing solenoid valve and the locking cylinder pressure relief solenoid valve, the control of the pressurizing and pressure relief actions of the locking cylinder is realized, ensuring that the key components of the multi-cylinder cone crusher 1 can be firmly locked during operation, improving the safety and stability of the equipment. By setting the discharge port enlarging solenoid valve and the discharge port reducing solenoid valve, the control of the discharge port enlarging and reducing actions is realized, enabling the size of the discharge port to be precisely adjusted according to production requirements, optimizing the crushing process, and improving production efficiency. By setting the safety cylinder rising solenoid valve and the safety cylinder falling solenoid valve, the control of the safety cylinder lifting and lowering actions is realized, ensuring timely response in case of abnormal situations and protecting the equipment from damage. The solenoid valves are all connected to the output end of the controller 2, realizing the automation and intelligence of the control process. According to the preset algorithm and the parameters collected by the first, second, and third sensor modules, the working states of each solenoid valve can be automatically adjusted to reduce manual intervention and improve production efficiency.

[0036] Preferably, referring to the attached Figures 3 - 5 , the soft start module includes a main circuit breaker Q1, a main motor M1, a soft starter NJR1, a bypass contactor KM0.

[0037] By using a soft start device to drive the main motor, the speed of the motor can be smoothly increased, thereby avoiding excessive starting current and mechanical impact force during the driving instant, which is beneficial to protecting the transmission system and crushing components of the multi-cylinder cone crusher, extending the service life of the device. Moreover, the soft start method of the main motor can effectively reduce the impact on the power grid during starting, reduce the voltage fluctuation of the power grid, thereby ensuring the stable operation of the power grid and avoiding adverse effects on other electrical equipment. Compared with the traditional direct full-voltage drive method, the soft starter NJR1 can gradually increase the load of the main motor M1, enabling the main motor M1 to more effectively utilize electric energy during the process from the stationary state to the rated speed, realizing the efficient utilization of energy. By setting the connection between the controller 2 and the soft starter NJR1, and using the output of the controller 2 to control the soft starter NJR1, the automation level of the device is improved.

By setting the intermediate relays KA1 and KA2, the controller 2 is used to control the on and off of the main contact of the intermediate relay KA1, thereby indirectly controlling the operation of the soft starter, increasing the flexibility and accuracy of the control. And by setting the intermediate relay KA2 to be connected to the contact signal end of the soft starter, the coil of the bypass contactor KM0 can be automatically controlled according to the state of the soft starter, thereby realizing automatic starting and switching.
