Description

Technical Field

[0001] The present invention belongs to the technical field of mobile crushing stations, and in particular relates to a control method for an anti-blocking system of a mobile impact crushing station. Background Art

[0002] In recent years, the amount of construction waste generated during urban development has increased significantly. To reduce environmental pollution and recycle this waste, large pieces of construction waste need to be crushed. However, this waste is scattered and mostly located within cities, making it unsuitable for large equipment to handle. Mobile impact crushing stations have a high chassis and a body width smaller than that of commercial semi-trailers, making them easy to transport and can be quickly and easily transferred between various construction sites.

[0003] During operation, a mobile impact crusher can be blocked by a variety of factors, including material being piled up at the feed port, the crusher's reduced handling capacity due to overload, and the discharge conveyor's malfunction. As an all-in-one design, mobile impact crushers are highly integrated and compact. Once a blockage occurs, it's extremely difficult to clear, preventing the crusher from operating normally and continuously, impacting project schedules and causing losses for customers. Summary of the Invention

[0004] In order to solve the problem of frequent material blockage in equipment, the present invention provides a control method for an anti-blocking system of a mobile impact crushing station, which improves the continuous operation capability of the equipment, reduces equipment downtime, and increases user benefits.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] A method for controlling an anti-blocking system of a mobile impact crushing station includes a hydraulic control system, a monitoring system, and an anti-blocking adjustment system. The hydraulic control system controls the movement of each oil cylinder in the anti-blocking system. The monitoring system collects information for the anti-blocking adjustment system, and the anti-blocking adjustment system controls the hydraulic control system to perform anti-blocking control.

[0007] The anti-blocking material adjustment system monitors the main engine power, the main engine feed port status and the power of the material conveying components, and performs anti-blocking material control according to the main engine power and the material level of the main engine feed port.

[0008] Furthermore, a control method for the anti-blocking system of a mobile impact crushing station includes automatic adjustment control of the opening of the main machine feed port, automatic release adjustment control of the main machine first-level impact plate, automatic release adjustment control of the main machine second-level impact plate, and automatic adjustment control of the feeder;

[0009] The main engine feed port opening is automatically adjusted and controlled: when the main engine power is lower than the lower limit set value and the main engine feed port material exceeds the limit, the anti-blocking adjustment system controls the hydraulic control system to adjust the reversing valve III, so that the feed port oil cylinder moves and the feed port is enlarged; after the main engine feed port material is in the normal position, the anti-blocking adjustment system controls the hydraulic control system to adjust the reversing valve III, so that the feed port oil cylinder descends and the feed port state is restored;

[0010] The main engine's first-level impact plate automatic release adjustment control: when the main engine power is between the lower limit setting value and the upper limit setting value and the material at the main engine feed port exceeds the limit, the anti-blocking adjustment system controls the hydraulic control system to adjust the reversing valve II, so that the main engine's first-level impact plate cylinder moves up and down to release the stuck material;

[0011] The automatic release adjustment control of the secondary impact plate of the main engine: when the power of the main engine is greater than the upper limit set value and the material at the main engine feed port does not exceed the limit, the anti-blocking adjustment system controls the hydraulic control system to adjust the reversing valve I, so that the oil cylinder of the secondary impact plate of the main engine retreats, and the material trapped in the main engine is quickly released; after the load of the main engine returns to normal, the anti-blocking adjustment system controls the hydraulic control system to adjust the reversing valve I, so that the oil cylinder of the secondary impact plate of the main engine advances and returns to normal state;

[0012] The feeder automatically adjusts and controls: when the host power is greater than the upper limit setting value and the material at the host feed port exceeds the limit, the anti-blocking adjustment system controls the feeder to stop feeding, and resumes feeding after the host power and the material at the host feed port return to normal; if the power of the material conveying component exceeds the limit value, the anti-blocking adjustment system controls the feeder to stop feeding.

[0013] Reduce the feeding speed and resume the feeding speed after the power of the material conveying components returns to normal.

[0014] Furthermore, the monitoring system mainly includes power monitoring and host feed port status monitoring.

[0015] Furthermore, the power monitoring mainly includes host power monitoring and material conveying component power monitoring; the host feed port status monitoring mainly includes a material level detection device.

[0016] The present invention prevents equipment blockage by detecting the material level at the main machine feed port, monitoring the main machine power, monitoring the power of the material conveying components to control feeding, and early intervention of the main machine feed port adjustment cylinder, the main machine first-level impact plate cylinder, and the main machine second-level impact plate cylinder, thereby improving the equipment's ability to operate continuously, reducing equipment downtime, and increasing user benefits.

[0020] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] This invention provides a method for controlling the anti-blocking system of a mobile impact crushing station. This method utilizes a hydraulic control system, a monitoring system, and an anti-blocking adjustment system. The hydraulic control system primarily controls the operation of the main machine's feed inlet cylinder, the main machine's first-stage impact plate cylinder, and the main machine's second-stage impact plate cylinder. The monitoring system collects information for the anti-blocking adjustment system and, when an anomaly is detected, proactively intervenes in the hydraulic control system to prevent blockages. The following details the components of this invention.

[0022] 1. Hydraulic control system

[0023] like Figure 1 As shown, the hydraulic control system is the actuator of the present invention's functions. It controls each cylinder by controlling the on / off switching of each solenoid valve. It includes a fuel tank 1, hydraulic pump 2, filter 3, relief valve I4, relief valve II5, secondary impact plate cylinder 6, primary impact plate cylinder 7, feed inlet cylinder 8, reversing valve I9, reversing valve II10, and reversing valve III11. Fuel tank 1 is used to store fluid, hydraulic pump 2 pumps fluid, filter 3 filters impurities from the hydraulic oil, and relief valve III provides a hydraulic oil overflow channel when system pressure exceeds a set value. Secondary impact plate cylinder 6 adjusts the size of the main engine's discharge port, primary impact plate cylinder 7 adjusts the distance between the primary impact plate and the main engine's rotor, and feed inlet cylinder 8 adjusts the size of the main engine's feed inlet 13. Reversing valve I9 ​​controls the forward and reverse movement of secondary impact plate cylinder 6, reversing valve II10 controls the forward and reverse movement of primary impact plate cylinder 7, and reversing valve III11 controls the forward and reverse movement of feed inlet cylinder 8.

[0024] The hydraulic pump 2 is connected to the oil tank 1 and the filter 3. The filter 3 is connected to the hydraulic pump 2 and the relief valve I4, the reversing valve I9, the reversing valve II10, and the reversing valve III11. The reversing valve I9 ​​is ​​connected to the filter 3, the relief valve I4, the relief valve II5, and the oil tank 1. The reversing valve II10 is connected to the filter 3, the relief valve I4, the first-level impact plate cylinder 7, and the oil tank 1. The reversing valve III11 is connected to the filter 3, the relief valve I4, the feed inlet cylinder 8, and the oil tank 1. The relief valve II5 is connected to the reversing valve I9 ​​and the second-level impact plate cylinder 6. The second-level impact plate cylinder 6 is connected to the relief valve II5 and the reversing valve I9. The first-level impact plate cylinder 7 is connected to the reversing valve II10, and the feed inlet cylinder 8 is connected to the reversing valve III11.

[0025] 2. Monitoring system

[0026] The monitoring system mainly includes power monitoring and host feed port status monitoring. The power monitoring mainly includes host power monitoring and power monitoring of material conveying components that are prone to blockage. The host feed port status monitoring mainly includes material level detection device 14. The monitoring system provides data support for anti-blocking control.

[0027] 3. Anti-blocking material adjustment system

[0028] like Figure 2 and Figure 3 As shown, the anti-blocking adjustment system mainly includes four parts of adjustment: first, automatic adjustment of the main machine's feed inlet opening; second, automatic release adjustment of the main machine's first-stage impact plate; third, automatic release adjustment of the main machine's second-stage impact plate; and fourth, automatic adjustment of the feeder. Through this combination of four adjustments, the purpose of preventing equipment blockage is achieved. The following details the above adjustment processes:

[0029] 3.1 Automatic adjustment of the opening of the main machine feed port

[0030] The system monitors the main engine power and the status of the main engine feed port. When the main engine power falls below the lower limit and the material in the main engine feed port 13 exceeds the limit, it indicates that there is no material inside the main engine and that material is accumulating at the feed port. At this point, the reversing valve III 11 needs to be adjusted to raise the feed port cylinder 8, thereby increasing the size of the main engine feed port 13 and allowing the material to enter the main engine smoothly. When the material in the main engine feed port 13 is at the normal position, the reversing valve III 11 is adjusted to lower the feed port cylinder 8, restoring the feed port's status.

[0031] 3.2 Automatic release adjustment of the main engine's first-level impact plate blockage

[0032] The system monitors the main engine power and the status of the main engine feed port. When the main engine power is between the lower and upper set points and the material at the main engine feed port 13 exceeds the limit, it indicates that there is material inside the main engine, but the material is entering the main engine very slowly, and the material processing speed is very slow, resulting in material accumulation at the feed port. This operating condition occurs because a large amount of large material is stuck on the main engine's first-stage impact plate, affecting the main engine's material processing speed. In this case, the main engine's first-stage impact plate cylinder 7 needs to be adjusted by adjusting the reversing valve II 10 to move the main engine's first-stage impact plate cylinder 7 up and down, releasing the material stuck on the first-stage impact plate and allowing it to fall onto the main engine rotor, thereby restoring the main engine's material processing capacity.

[0033] 3.3 Automatic release adjustment of the secondary impact plate of the main engine

[0034] The system monitors the main engine power and the status of the main engine's feed port. When the main engine power exceeds the upper limit and the material at the main engine feed port 13 does not exceed the limit, it indicates that a large amount of material is being processed within the main engine. If this large amount of material is not promptly processed, it may cause the main engine to shut down due to overload and material blockage. In this case, it is necessary to adjust the reversing valve I9 ​​to retract the main engine's secondary impact plate cylinder 6, thereby quickly releasing the material trapped in the main engine and reducing the main engine load. Once the main engine load returns to normal, the reversing valve I9 ​​is ​​adjusted to advance the secondary impact plate cylinder 6, restoring the main engine to normal state.

[0035] 3.4 Automatic feeding adjustment

[0036] The system monitors the host power, host feed port status, and material conveying component power (vibrating discharger power, main conveyor power). When the host power is greater than the upper limit set value and the material at the host feed port 13 exceeds the limit, it indicates that the feeder 12 is feeding too fast. If feeding continues at this time, the host will stop due to overload and become blocked. At this time, the feeder 12 needs to stop feeding and resume feeding after the host power and the material at the host feed port return to normal. If the monitoring shows that the vibrating discharger or main conveyor power exceeds the limit, it means that they are about to reach their power limit. If they are not processed, they will stop working and cause blockage. At this time, it is necessary to reduce their load by reducing the feeding speed. After the power of the vibrating discharger and main conveyor returns to normal, the feeding speed will return to its original state.

[0037] Through the combined adjustment of the above four steps, the frequent blockage of mobile impact crusher can be effectively solved and the production efficiency of the equipment can be improved.
