Description

Technical Field

[0001] This utility model belongs to the technical field of mining production equipment, specifically relating to a heat dissipation device for a mining feed motor. Background Technology

[0002] Vibratory feeders are widely used in mining operations, metallurgy, chemical industry, building materials, coal and other industries. In the mining process, vibratory feeders use a vibratory motor as the power source, generally called a feed motor. The centrifugal force generated by the rotation of eccentric blocks installed at both ends of the main shaft drives the equipment to vibrate, causing the material to jump forward along a parabolic trajectory, thus achieving uniform ore discharge. It also effectively prevents ore blockage and adhesion, improving the efficiency and quality of ore discharge operations.

[0003] Currently, mine feed motors are frequently started and run for long periods during ore discharge. Coupled with poor ventilation in the underground environment, they are in a state of heat for extended periods, which leads to insulation aging, reduced overall motor performance, and faults such as phase-to-phase short circuits and grounding. This will affect the production of the entire system. Existing cooling methods are not suitable for the mining environment and cannot achieve effective cooling. Utility Model Content

[0004] This utility model provides a heat dissipation device for a mine feed motor, which solves the problem that existing feed motors overheat due to prolonged use and that existing cooling methods cannot achieve the desired cooling effect.

[0005] The technical solution of this utility model is: a heat dissipation device for a mine feed motor, including a main air supply pipeline and a feed motor, an air outlet pipe is provided around the feed motor, a branch pipe is provided on the main air supply pipeline, the end of the branch pipe is connected to the air outlet pipe, and multiple air outlets are provided on the air outlet pipe.

[0006] As a further improvement of this utility model, a solenoid valve is provided on the branch pipe, and the power supply of the solenoid valve and the feed motor is connected to a PLC controller.

[0007] As a further improvement of this utility model, the air outlet is located directly opposite the feed motor, which facilitates the cooling of the feed motor.

[0008] As a further improvement of this utility model, the air outlet pipe is inverted "T" shape, which facilitates sufficient heat dissipation for the mining motor.

[0009] The beneficial effects of this utility model are as follows: This utility model provides high-pressure air for cooling through the main air supply pipeline of the existing mine air supply system, and relies on branch pipes and outlet pipes to cool the feed motor. This eliminates the need for additional cooling devices and avoids other energy losses. Furthermore, this utility model uses a PLC controller to interlock the solenoid valve with the feed motor. Starting the feed motor simultaneously activates the solenoid valve, cooling the feed electrode through the outlet without requiring separate activation, effectively improving the applicability of the heat dissipation device. This utility model has a simple structure, stable operation, avoids the difficulty of installing heat dissipation devices in mine terrain, improves the heat dissipation effect of the feed motor, enhances the practicality of the heat dissipation device, and has strong applicability. It optimizes the heat dissipation method and device structure of the feed motor, and plays a significant role in improving the safety and overall efficiency of the mining production system.

[0012] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0013] like Figure 1 As shown, a heat dissipation device for a mine feed motor includes a main air supply line 1 and a feed motor 8. An air outlet pipe 3 is provided around the feed motor 8. A branch pipe 2 is provided on the main air supply line 1. The end of the branch pipe 2 is connected to the air outlet pipe 3. The air outlet pipe 3 is provided with multiple air outlets 9.

[0014] A solenoid valve 7 is installed on the branch pipe 3, and the power supply of the solenoid valve 7 and the feed motor 8 is connected to a PLC controller 6.

[0015] Air outlet 9 is located directly opposite the feed motor 8.

[0016] The exhaust duct 3 is inverted "T" shape, which facilitates sufficient heat dissipation for the mine motor.

[0017] In use, branch pipe 2 is connected to main air supply line 1 via first valve 4. Branch pipe 2 is routed to a position above feed motor 8 and fixed. The other end of branch pipe 2 is connected to outlet pipe 3 via second valve 5. Branch pipe 2 can be freely disassembled via first valve 4 and second valve 5 for easy adjustment of branch pipe 2 and outlet pipe 3. Under normal circumstances, both first valve 4 and second valve 5 are in the normally open state. The air supply branch pipe 2 is controlled by the opening and closing of solenoid valve 7, which is controlled by PLC controller 6. When feed motor 8 starts, PLC controller 6 receives a signal and feeds it back to solenoid valve 7, which immediately opens. The inverted "T"-shaped outlet pipe 3 discharges air through multiple outlet holes 9 to cool feed motor 8. When feed motor 8 stops, PLC controller 6 receives a signal and feeds it back to solenoid valve 7 after a 3-minute delay, at which point solenoid valve 7 closes.
