Description

Technical Field

[0001] This utility model relates to the field of wind power generation equipment technology, and in particular to a jaw crusher with a temperature regulation device. Background Technology

[0002] Jaw crushers are core crushing equipment in industries such as metallurgy, mining, and building materials. Their operational stability directly affects the operating efficiency and economic benefits of the entire production line. The existing CT6080 jaw crusher, a commonly used model, can handle materials with a feed size of up to 1300mm and a compressive strength not exceeding 250MPa. However, in actual operation, the moving jaw bearing frequently experiences overheating. Testing revealed the following reasons: First, the lubrication system is prone to problems such as insufficient oil quantity, mismatched lubricant viscosity, or oxidation and deterioration, leading to oil film rupture and the bearing entering a state of "dry friction" or "semi-dry friction." Second, crushers often require long periods of continuous operation, with the jaw bearing continuously bearing impact loads. The rate of frictional heat generation far exceeds the rate of heat dissipation, causing heat to gradually accumulate. Third, the operating environment often presents harsh conditions such as dust intrusion and high ambient temperatures, preventing the timely dissipation of frictional heat generated by the bearing. Overheating of the bearing not only shortens its service life and increases grease consumption and maintenance costs but also reduces equipment operating rates, resulting in significant economic losses for enterprises.

[0003] In summary, how to provide a jaw crusher with real-time detection and control of the temperature of the moving jaw bearing is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] This utility model provides a jaw crusher with a temperature regulating device. Please refer to the appendix of the instruction manual. Figures 1 to 3 This application includes a support frame 11 for mounting various components. Two parallel frame bearing seats 2 are provided on one side of the support frame 11 along the horizontal direction. An eccentric shaft 1 is vertically inserted through the end faces of the two frame bearing seats 2. The eccentric shaft 1 is horizontally positioned. Further, a movable jaw body 3 is provided between each frame bearing seat 2, also passing through the outer periphery of the eccentric shaft 1. It should be noted that the eccentric shaft 1 includes a connecting part and an eccentric part. The connecting part is symmetrically arranged at both ends of the eccentric part, extending into each frame bearing seat 2 and connected to a drive device. The connecting part receives the power output from the drive device and drives the eccentric part to rotate. The movable jaw body 3, sleeved on the outer periphery of the drive device, reciprocates up and down to crush the ore. Preferably, two first bearings 4 are provided between the movable jaw body 3 and the eccentric shaft 1. Each first bearing 4 is located inside the two side ports of the movable jaw body 3. Each first bearing 4 is used to reduce the friction force experienced by the eccentric shaft 1 during rotation, making the rotation process smoother. Two air inlets 6 are provided on the side wall of the movable jaw body 3. The extension direction of each air inlet 6 is set at an angle to the axis of the first bearing 4, so that the port of each air inlet 6 near the inner cavity of the movable jaw body 3 corresponds to the end face of the first bearing 4. The air inlets 6 are connected to an air intake assembly, which blows airflow into the inner cavity of the movable jaw body 3 through the air inlets 6. The airflow absorbs the heat generated during the rotation and friction of the first bearing 4, thus cooling the first bearing 4. Preferably, the air intake assembly is signal-connected to a temperature sensor, which is used to detect the surface temperature of each first bearing 4. When the temperature exceeds a preset safety threshold, the air intake assembly is activated to cool down each first bearing 4.

[0028] Preferably, a second bearing 5 is provided between the frame bearing seat 2 and the eccentric shaft 1. The second bearing 5 is used to assist the rotation of the eccentric shaft 1 and to reduce the friction force experienced by the eccentric shaft 1 during rotation.

[0029] Please continue to refer to the instruction manual appendix. Figure 1Each air inlet 6 is located between two first bearings 4. The axis of each air inlet 6 and the axis of the exhaust port 7 are both located in the same plane, and the plane is horizontally set. Preferably, the exhaust port 7 can be specifically a first exhaust port and a second exhaust port. Since each exhaust port 7 is located between the first bearings 4 and supplies airflow to the first bearings 4 on both sides, the first exhaust port and the second exhaust port extend in opposite directions, so that the ports of the first exhaust port and the second exhaust port in the inner cavity of the moving jaw body 3 correspond to each first bearing 4. Preferably, the angle between the axes of the first and second exhaust holes and the axis of the moving jaw body 3 is 45°, and the first and second exhaust holes are perpendicular to each other. It should be noted that the first bearing 4 includes an inner ring, an outer ring, and cylindrical balls sandwiched between the two. The axis of the exhaust hole 7 can intersect with the axis of any cylindrical ball on the same side, and the intersection point is located on the end face of the cylindrical ball facing the inner cavity of the moving jaw body 3. That is, the airflow output from the exhaust hole 7 can always be evenly blown to the end face of the cylindrical ball. While ensuring that the airflow stably cools the first bearing 4, it avoids the airflow directly blowing onto the grease of the first bearing 4. If the blowing direction of the exhaust hole 7 is deviated, after a long period of airflow blowing, the grease on the outside of each cylindrical ball will be blown away or blown off, resulting in poor lubrication of the first bearing 4, aggravating wear or lubrication failure.

[0030] Correspondingly, an exhaust port 7 is also provided on the side wall of the moving jaw body 3. The exhaust port 7 is also located between each of the first bearings 4, and the distance from the axis of the exhaust port 7 to each of the first bearings 4 is equal. The extension direction of the exhaust port 7 is vertical. That is to say, the axis of the exhaust port 7 is perpendicular to the plane where the axis of the first bearing 4 and the axis of the air inlet 6 coexist. Preferably, when this application is fixed on a horizontal ground, the exhaust port 7 is located above the entire equipment, and the distance from each air inlet 6 to the upper and lower ends of the moving jaw body 3 is equal. This arrangement provides an appropriate distance between the air inlet 6 and the exhaust port 7. That is, after the outside cold air enters the inner cavity of the moving jaw body 3 through the air inlet 6, it cools the first bearing 4. Then, the cold air diffuses evenly in the inner cavity of the moving jaw body 3, and the original high temperature air is discharged from the exhaust port 7, so that the first bearing 4 rotates at a lower ambient temperature.

[0031] Preferably, the air intake assembly is provided with a quick connector and the inner wall of the air intake hole 6 is provided with a threaded section. The quick connector can be threadedly connected to the air intake hole 6, which improves the ease of disassembly and assembly of this application while ensuring connection stability and sealing.

[0032] Furthermore, a detection hole 8 is provided on the side wall of the movable jaw body 3. The detection hole 8 extends into the inner cavity of the movable jaw body 3 and corresponds to the side wall of the first bearing 4. Preferably, the temperature sensor is provided with a temperature measuring probe. The temperature measuring probe passes through the detection hole 8 so that the end of the temperature measuring probe abuts against the side wall of the first bearing 4. The temperature measuring probe is used to detect the temperature of the side wall of the first bearing 4. When inserting the temperature measuring probe, a certain amount of grease is pre-filled in the detection hole 8. After the temperature measuring probe is inserted into the detection hole 8, the grease lubricates the end of the temperature measuring probe, reduces the friction force on the temperature measuring probe, and fills the gap between the temperature measuring probe and the temperature measuring hole to prevent external dust and debris from entering the inner cavity of the movable jaw body 3 through the gap.

[0033] Preferably, a vent cap 9 is provided at the port of the exhaust hole 7 on the side opposite to the inner cavity of the moving jaw body 3. The vent cap 9 includes a plug-in part and a sealing part, wherein the diameter of the sealing part is larger than the diameter of the plug-in part. The plug-in part can extend into the exhaust hole 7, and the side wall of the plug-in part fits against the inner wall of the exhaust hole 7. When the plug-in part is fully extended into the exhaust hole 7, the sealing part covers the port of the exhaust hole 7. In addition, the vent cap 9 has a through hole along its own axis, which connects the sealing part and the plug-in part and communicates with the exhaust hole 7. A filter screen is provided at the port of the through hole. After the cooling of the first bearing 4 is completed, air is discharged through the exhaust hole 7 and the through hole. The filter screen is used to prevent external debris from entering the inner cavity of the moving jaw body 3. In addition, an oil injection hole 10 is provided on the side wall of the moving jaw body 3. The oil injection hole 10 corresponds to the side wall of the first bearing 4 and is used to fill lubricating oil between the first bearing 4 and the moving jaw body 3.

[0034] In addition, this application also includes a control assembly, which is used to receive temperature signals from temperature sensors. When the temperature exceeds the threshold range, the control assembly controls the operation of the air intake component to cool the first bearing 4. The control assembly is connected to an operation panel, and the operator can monitor the temperature of the first bearing 4 in real time through the operation panel. The operation panel is also equipped with an alarm device. If the temperature of the first bearing 4 does not drop to a safe temperature after the air intake component has been running for a period of time, the alarm device will be activated to remind the operator to check the crusher. The operator can stop the operation of the crusher through the operation panel.

[0035] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0036] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
