Description

Technical Field

[0001] The utility model relates to the technical field of ore processing, in particular to a combined circulation cooling device for a motor. Background Art

[0002] Ore crusher is a machine that uses a high-speed rotating crushing mechanism to crush irregular ores into tiny sizes. The crusher mainly drives the crushing mechanism to move through the motor, and the crushing mechanism crushes the ore in the form of high-speed impact. In order to facilitate heat dissipation, the motor of the conventional crusher is usually installed on the outside of the crusher. For example, Chinese patent CN202022873583.2 discloses a jaw crusher used in ore mining and Chinese patent CN201621208613.5 discloses a repeated crushing ore crusher. The crushers are all driven by the high-speed rotation of the motor installed on the side to drive the crushing mechanism to crush the ore. However, in actual use, it is found that the heat dissipation effect of the motor is not obvious, and because the working motor will continue to heat up when the motor is running at high speed, when the temperature reaches a certain limit, it is necessary to stop the heat dissipation to prevent the motor of the crusher from overheating and damage; but frequent shutdown of heat dissipation is not conducive to large-scale ore crushing operations, and also affects the service life of the working motor to a certain extent. The crusher cannot be fully and effectively utilized, resulting in equipment waste. In order to extend the working time and service life of the motor, the temperature conditions during the operation of the crusher must be maintained, and the temperature of the working motor must be reduced during operation. Utility Model Content

[0003] In view of the shortcomings that the motor of the above-mentioned crusher is easily damaged by overheating during use and needs to be shut down frequently, resulting in the crusher cannot be fully and effectively utilized, the utility model provides a combined circulating cooling device for the motor, which can facilitate the heat dissipation of the crusher motor during the ore crushing process, reduce motor shutdowns and extend the service life of the crusher.

[0004] To achieve the above purpose, the technical solution of the utility model is as follows:

[0005] A combined circulating cooling device for a motor comprises a mounting shell, a circulating water cooling component and an exhaust fan; the mounting shell is formed by a combination of waterproof and breathable baffles, and a support box is connected to the bottom of the mounting shell, and an annular plate made of the waterproof and breathable baffle is provided inside; an annular cavity is formed between the annular plate and the mounting shell, the circulating water cooling component is installed in the annular cavity, a temperature sensor is installed on the inner side of the annular plate, and a controller is installed on the outer side of the mounting shell, wherein the controller is respectively connected to the temperature sensor, the circulating water cooling component and the exhaust fan; the exhaust fan is installed in the middle of the support box, an air outlet is also provided on the side, and the top is connected to the annular cavity.

[0006] Furthermore, the circulating water cooling component includes an inner circulation pipeline and an outer circulation pipeline arranged in an annular cavity, wherein the water inlets of the inner circulation pipeline and the outer circulation pipeline are provided with solenoid valves respectively connected to the controller; the water inlet and the water outlet of the inner circulation pipeline and the outer circulation pipeline respectively extend outward through the mounting shell, and the outer circulation pipeline is arranged close to one side of the mounting shell. Before use, the water inlet and outlet of the inner circulation pipeline and the outer circulation pipeline should be connected to the circulating water circuit of the factory respectively; during use, the inner circulation pipeline or the outer circulation pipeline can be controlled by controlling the solenoid valve by the controller. When the motor works for a short time but the temperature is high, the switch valve of the inner circulation pipeline can be opened by the controller; when the motor works for a long time, the solenoid valves of the inner circulation pipeline and the outer circulation pipeline can be opened at the same time; after the solenoid valve is opened, the water in the factory's circulating water circuit enters the inner circulation pipeline and the outer circulation pipeline, and exchanges heat with the pipeline to cool the inner circulation pipeline and the outer circulation pipeline. After the air enters, it contacts the pipe walls of the inner circulation pipeline and the outer circulation pipeline to cool down, realizing water cooling operation; the cooperation of the inner circulation pipeline and the outer circulation pipeline can adapt to the cooling needs of the motor under different working conditions, and can also effectively avoid the waste of resources. At the same time, the structure is simple and can be controlled by the solenoid valve, which is convenient to use.

[0007] Furthermore, a guide plate is provided on the inner side of the annular plate. The hot air generated by the motor is guided through the guide plate, so that the hot air can be quickly drawn away by the exhaust assembly, thereby improving the heat dissipation effect of the motor.

[0008] Furthermore, a water sensor for water leakage monitoring is provided on the bottom plate inside the installation shell. When the circulating water cooling component leaks, water will fall into the bottom plate of the support box.

[0009] Furthermore, a humidity sensor connected to the controller is provided on the side wall inside the installation shell, and a ventilation column connected to the support box is provided on the bottom plate; a dehumidification mechanism connected to the controller is also provided inside the support box. The humidity sensor monitors the internal humidity of the annular cavity. During use, a humidity warning value is preset. If the humidity monitored by the humidity sensor is higher than the set humidity warning value, the controller turns on the dehumidification mechanism and the exhaust fan. When the exhaust fan exhausts air, the air in the installation shell and the annular cavity enters the support box along the ventilation column, and the dehumidification mechanism removes moisture.

[0011] Furthermore, the waterproof breathable partition includes a plastic mesh and a waterproof breathable membrane, wherein the plastic mesh is connected to both sides of the waterproof breathable membrane to form a composite plate. The plastic mesh of the waterproof breathable partition is used for support, and the waterproof breathable effect is achieved by cooperating with the waterproof breathable membrane, which meets the requirements of simple plate material, low processing cost and good use effect.

[0012] The use of the utility model:

[0013] When in use, the motor of the crusher is installed in the installation shell. When the crusher is in use, the motor rotates at high speed, and the temperature sensor monitors the internal temperature of the installation shell. When the temperature is higher than the preset value, the controller turns on the connected circulating cold water component and the exhaust fan, the circulating cold water component circulates and cools down, the exhaust fan ventilates, draws out the air inside the installation shell, and discharges it outside the device through the air outlet. At this time, the air outside the installation shell will enter the annular cavity through the waterproof and breathable partition, and the air can be cooled by the circulating water cooling component. The cooled air passes through the annular plate and enters the interior of the installation shell, so that the heat generated by the motor operation is taken away, and then the high-temperature air in the installation shell is discharged through the exhaust group to realize the cooling operation of the motor.
