Description

{INTELLIGENT CONE CRUSHER}

The present invention relates to a cone crusher, and more particularly, to an intelligent cone crusher that detects and informs thickness changes without changing the structure of a liner (cone and mantle), and is easy to operate by detecting liner thickness and unifying gap setting. will be.

Generally, building waste, quarry stone, and stone collected from a mine have a crushing process that is crushed to a certain size through a crusher.

The crusher includes a jaw crusher for crushing a relatively large mass of aggregate, and a cone crusher for crushing aggregate crushed from the jaw crusher to a smaller size.

The cone crusher is an apparatus for crushing and crushing an aggregate between an eccentrically rotated cone-shaped mantle and a fixed concealed cage, and comprises a substantially cylindrical main frame and an eccentric internal eccentric Shaped mantle core and mantle coupled to the outer circumferential surface of the rotating shaft, a top frame seated on the top of the main frame, And a top cell with a spaced cone cave. There is also a cone crusher that drives the mantle core without using a rotary shaft.

In addition, there is provided a releasing means between the top frame and the main frame for supporting a vertical load generated during the crushing process of the aggregate.

According to the conventional cone crusher constructed as described above, the drive shaft is rotated by the rotational force of the pulley, and the bevel gear meshed with each other by the rotational force of the drive shaft is rotated to rotate the extensible wheel. Subsequently, the rotation axis eccentric to the centrifugal rotates and the gap between the mantle and the cone is narrowed or widened while the mantle core is driven, so that the charged aggregate is crushed.

The cone crusher must be replaced at an appropriate time because the mantle and cone are getting worn out as the operation time passes. If the mantle and cone cave are not properly replaced, the equipment body may be damaged. In other words, it is very important to know when to replace the mantle and cone.

US patent 6,129, 297 discloses a method for monitoring the progress of wear of cone crusher wear parts. According to the present invention, holes are formed at the maximum depth at which abrasion is allowed on the back surface of the wear parts of the cone crusher, and these holes are filled with a material such as a color composition. As the erosion of the wear parts progresses to this hole, the color composition spreads on the surface of the wear parts of the cone crusher, thereby allowing the driver to monitor the wear status. However, since this method can not obtain information during operation of the cone crusher, the cone crusher must be stopped for the inspection, the production capacity is lowered, and since the driver must approach the cone crusher closely and constantly monitor with the naked eye, There is also a risk of safety.

Korean Patent No. 10-1087961 discloses that the progress of the cone wear is measured by an electrode type abrasion sensor and the progress of the wear of the mantle is attained by combining the gas release rod and the gas detection sensor embedded in the upper portion of the cone, Wherein the electrode wear sensor comprises: a plurality of conductor electrode loops surrounded by an insulating material; External metal shield; A wear signal is generated as the end contact of the conductor electrode loop is physically damaged when the first contact point of the conductor electrode loop reaches the contact point of the conductor electrode loop to induce a wear alarm of the cone cube by the signal processor, And the contact point of the conductor electrode loop is ruptured when reaching the second to third positions due to the weight of the abrasion, so that the abrasion signal according to each depth can be obtained step by step. A metal tube connected to the pressure vessel; And a cylindrical metal body, wherein the metal tube is inserted into a plurality of tube insertion holes having different depths, and a mounting fixing thread is formed on the metal body, wherein wear is progressed so that the end of the first closed metal tube A specific gas stored in the pressure vessel is ejected and released to a space between the mantle and the cone. The discharged gas is detected through the gas detection sensor, and the high / The wearer can monitor the state of wear and tear remotely based on the on-line wear rate signal. However, if the wear sensor is installed in the cone and the gas detection sensor is placed in the mantle It is not realistic to install it, especially gas detection sensor and related electronics PL is not realistic, it is very difficult.

The following terms are defined in consideration of the functions of the present invention, and these may be changed according to the intention of the user, the operator, or the like. Therefore, the definition should be based on the contents throughout this specification.

1 to 3, an intelligent cone crusher according to the present invention includes a main frame 10 and a main frame 10 which are rotatably installed in an eccentric state A balance weight 31 for holding the vibration of the rotating shaft 20, a driving means 40 for rotating the rotating shaft 20, a cone-shaped mantle core 20 coupled to the upper outer peripheral surface of the rotating shaft 20, A mantle 60 installed on the mantle core 50, a top frame 70 seated on the main frame 10, a top cell 80 vertically installed on the top frame 70, A gap setting means 100 for setting a gap between the cone 90 and the mantle 60, a release cylinder 200 for raising the top frame 70 upon overloading, A distance sensor 300 for detecting the movement distance of the top cell 80 or the distance between the top cell 80 and the top frame 70, A controller 400 for calculating a thickness change value of the cone 90 and the mantle 60 based on the value of the gap setting means 100 and a gap between the cone 90 and the mantle 60 set by the gap setting means 100, A monitor 500 for outputting a thickness value calculated by the controller 400, a temperature of oil circulating for lubrication of the sliding part, and the like, and an alarm 600 may be additionally constructed.

The main frame 10, the rotating shaft 20, the centrifugal 30, the driving means 40, the mantle core 50, the mantle 60, the top frame 70, the top cell 80, The gap setting means 100, and the release cylinder 200 are the same as those of the conventional cone crusher, and thus a detailed description thereof will be omitted, and only a novel configuration and a configuration related to the present invention will be described in detail.

The gap setting means 100 includes a motor 110 that generates power by receiving power and a driving gear 120 that is rotated by the motor 110, And a lifting gear (ring) 80 for lifting and lowering the top cell 80 while rotating by the rotation of the driving gear 120 to set a gap between the cone 90 fixed to the top cell 80 and the mantle 60, The present invention is constructed in such a manner that the change in thickness of the liner (the cone 90 and the mantle 60) is checked in conjunction with the gap setting means 100, There is a difference. That is, the conventional gap setting means is to match only the gap between the mantle 60 and the cone 90, and the present invention can be applied to the configuration of the mantle 60 and the cone 90 when the gap setting means 100 sets the gap. ).

The motor 110 is powered by the manual operation of the controller or the controller and the gap setting means 100 sets the gap between the mantle 60 and the conceal 90 The change in thickness of the mantle 60 and the cone cave 90 is calculated.

The distance sensor 300 measures the distance between the reference position (the top frame 70 or the main frame 10) and the top cell 80 or the moving distance of the top cell 80. [ The distance data measured by the distance sensor 300 is stored in the memory.

As the distance sensor 300, an ultrasonic-based light-emitting device is used.

The distance sensor 300 measures only the movement distance of the top cell 80 and the controller 400 controls the distance between the mantle 60 and the cone 90 by subtracting the current measured value of the distance sensor 300 from the previous measured value, Lt; / RTI >

According to the present invention, the change in thickness of the mantle 60 and the cone 90 is not confirmed, but the change in the thickness of the entire mantle 60 and the cone 90 is confirmed, It is possible to indicate the replacement time of the battery.

The controller 400 performs not only the calculation of the thickness of the liner but also various controls such as gap setting and load responsive control, and the details of the control can be found through the following control method.

As shown in FIG. 4, the monitor 500 displays the gap, the liner thickness, the motor load, and the oil temperature on the screen. FIG. 4 shows an example of the screen output method. It is possible.

The alarm 600 informs the emergency situation (the timing of replacing the liner, the timing of stopping the driving means, etc.), and for example, immediately before the end of the life of the liner, (40).

At this time, the controller 400 can stop and control the apparatus simultaneously with the output of the alarm 600.

The control method of the intelligent cone crusher according to the present invention is as follows.

1. Gap setting.

The gap is related to the grain size of the material to be crushed by the intelligent cone crusher and the gap is set periodically because it knows that the mantle 60 and the cone crate 90 are worn and that this wear increases the gap .

Gap setting can be set to manual mode by manual operation of the administrator or automatic mode by automatic control of the controller.

end. Manual mode.

When the manager operates the switch in the state where there is no object to be crushed in the cone crusher, the mantle 60 is at rest and the concave 90 is lowered by the gap setting means 100.

The load is not applied to the driving means 40 (or the rotating shaft 20) until the cone 90 touches the mantle 60 in the stopped state. However, when the cone 90 touches the mantle 60, 40 (or the rotary shaft 20) is suddenly subjected to a large load, and this time is confirmed as a zero point.

In this state, the gap of the set value is generated between the mantle 60 and the cone 90 by raising the cone 90 by a gap.

I. Automatic mode.

The automatic mode sets the gap through the control of the controller 400 at the time set by the manager. For example, when the controller 400 is stopped (at 8:00 am) The gap is set after lowering the cone 90 into the mantle 60 of the main body 10. This gap adjustment method is the same as the manual mode.

In this case, since the cone crusher can be operated at the setting time, the controller 400 confirms the driving of the driving means 40 or the rotary shaft 20, and does not set the gap in the operating state.

Therefore, the automatic mode also includes setting the gap in the state where the driving means 40 is stopped for at least one hour, for example, by confirming the stopping of the driving means 40 in addition to the method of setting the gap at the setting time.

At this time, there may be a crushed material between the mantle 60 and the cone cave 90. Therefore, in the automatic mode, the presence or absence of the crushed material is checked first, The stability and accuracy can be ensured through the process of making it. In the former (check for existence), a sensor can be installed at a position that is not interfered with from the feeding of the object to be crushed, and the object to be crushed can be checked. It is possible to remove the remaining fragments.

According to such a gap setting method, the gap (for example, 25 mm) is always maintained irrespective of the change in thickness of the mantle 60 and the cone 90.

2. Check liner thickness.

The present invention also identifies the liner thickness when setting the gap.

For example, the gap between the cone 90 and the mantle 60 is set to 25 mm, and the distance between the top cell 80 and the top frame 70 is initially zero. The gap between the cone 90 and the mantle 60 is always set to 25 mm through the gap setting process. In this process, the distance sensor 300 measures the distance between the top cell 80 and the top frame 70 or the distance traveled by the top cell 80, and this value is the change value of the liner thickness, (The cave 90 and the mantle 60) is 5 mm worn (total wear of the cone 90 and the mantle 60), the top cell 80 is moved to a position of 5 mm So that the distance between the top cell 80 and the top frame 70 is narrowed by 5 mm, and it is finally confirmed that the liner thickness is worn by 5 mm.

3. Load sensing control.

The load responsive control can be based on the load of the drive means 40 (or the rotary shaft 20) and can be controlled based on the temperature of the oil for lubrication (cooling).

The driving means load sensor senses the load of the driving means 40 (or the rotating shaft 20), and the controller 400 compares the current value with a previously stored reference value (set by the manufacturer or administrator) It is judged that the load is large (overloaded) when the reference value is matched with the reference value (including the abnormality), and the drive means 40 is stopped or controlled by the release means 200 to raise the top frame 70, Stop control.

The temperature sensor is mounted on the circulation path of the oil to detect the temperature of the oil. The controller 400 compares the current value detected by the temperature sensor with the previously stored reference value (set by the manufacturer or administrator) It is judged that the normal lubrication (cooling) is not performed and the driving means 40 is stopped or the top frame 70 is elevated by the releasing means 200, The conveyor is stopped and controlled.

Other operations are the same as those of known cone crushers, so a detailed description thereof will be omitted.

It is to be understood, however, that the invention is not to be limited to the specific forms thereof, which are to be considered as being limited to the specific embodiments disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit of the invention as defined by the appended claims. .
