Description

Technical Field

[0001] This utility model relates to the design field of ring die pellet mills, and in particular to the field of monitoring and control technology for ring die pellet mills, specifically a monitoring module for a pellet mill grease heating system. Background Technology

[0002] The existing automatic lubrication module for pellet mills adds semi-solid grease in low winter temperatures, resulting in low lubrication efficiency. The lubricating grease needs to be preheated to a certain temperature before being fed into the pellet mill's main shaft and pressure rollers to turn the semi-solid grease into a liquid state. If traditional electric heating is used, it will put a heavy burden on the existing pellet mill's power supply system and consume a lot of energy. Therefore, a section of shaft is extended at the drive shaft end outside the pellet mill's main shaft box via a connecting shaft. A bushing is then fitted on the outside of the extended shaft, and a channel is opened between the bushing and the shaft to allow the lubricating grease to absorb the heat generated by friction between the bushing and the shaft through heat conduction.

[0003] During the simulation test operation, the above structure often experiences problems such as oil leakage at the oil supply port or intermittent grease output at the oil outlet and low output flow. It is necessary to install a monitoring module on the oil supply port side of the heating channel to prevent the above situation from occurring by controlling the output level of the oil pump or increasing the speed of the pellet mill spindle.

[0004] The sensor in the monitoring module is directly inserted into the oil supply port side of the heating channel. During use, due to the large vibration of the above structure, the sensor will be displaced due to the vibration and eventually be pushed out by the grease due to the pressure in the oil supply channel, causing leakage. Summary of the Invention

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a monitoring module for a granulator grease heating system to solve the difficulties of the prior art.

[0006] To achieve the above and other related objectives, this utility model provides a monitoring module for a granulator grease heating system, comprising:

[0007] Base 1, which is bolted to one side of the main shaft box of the pellet mill;

[0008] Positioning support rod 2, which is welded and fastened to one side of base 1;

[0009] Vibration transmitting slide plate 3 is mounted on the side of the positioning support rod 2 away from the base 1, and the vibration transmitting slide plate 3 moves left and right along the positioning support rod 2;

[0010] Mounting base plate 4, the top of which is welded to the bottom of the vibration transmitting slide plate 3 on the side away from the positioning support rod 2;

[0011] The shock-absorbing plate 5 is disposed on the left or right side of the top of the mounting base plate 4;

[0012] Sensor 6 is threaded through the center of the damping plate 5 on the side away from the mounting base plate 4, and the bottom of sensor 6 passes through the bushing 7 to enter the heating channel.

[0013] According to the preferred embodiment, the base 1 is triangular in shape, and a slot 11 is provided on one side of the base 1. The slot 11 is engaged with the flange 8 on the outside of the granulator spindle box, and the base 1 is connected to the flange 8 by bolts.

[0014] According to the preferred embodiment, the mounting base plate 4 is provided with threaded holes 41 around its perimeter, and the bottom of the threaded holes 41 passes through the mounting base plate 4 and is located on the outside of the bushing 7.

[0015] According to the preferred embodiment, a hexagonal screw 42 is fitted inside the threaded hole 41, and the hexagonal screw 42 connects the mounting base plate 4 and the bushing 7.

[0016] According to the preferred embodiment, a weight reduction groove 31 is provided in the center of the vibration transmission slide plate 3.

[0017] According to the preferred embodiment, the mounting base plate 4 is T-shaped, and the bottom of the mounting base plate 4 is fitted into the mounting groove 71 corresponding to the top of the bushing 7.

[0018] According to the preferred embodiment, the shock-absorbing plate 5 has waist holes 51 on both the front and rear sides near the mounting base plate 4, and the waist holes 51 are sleeved on the outside of the hexagonal screw 42.

[0019] This utility model employs a base, positioning support rod, vibration transmission slide plate, mounting base plate, damping plate, and sensor to monitor the oil supply port pressure of the heating channel in the heating system in real time. If the pressure is too high, the oil output from the outlet is smooth, and the output flow of the oil pump is reduced. If the pressure is too low and the oil output from the outlet is intermittent, the output flow of the oil pump is increased. If the pressure is too high and the oil output from the outlet is intermittent, the pellet mill program is switched to increase the rotation speed of the pellet mill spindle. It is also equipped with two-stage damping brackets. The first stage has a damping plate with a connecting waist hole assembly design, which has a buffering effect and will not break the sensor compared to rigid fixation. The second stage has a vibration transmission slide plate, positioning support rod, and base to transmit part of the vibration to the external bracket, reducing the axial stress acting on the hexagonal bolt threaded rod and preventing the hexagonal bolt from loosening.

[0036] This utility model proposes a monitoring module for a granulator grease heating system, used for monitoring the process. This utility model has limitations on the length specifications of the heating system, but the structure of the base 1, positioning support rod 2, vibration transmission slide plate 3, mounting base plate 4, damping plate 5, and sensor 6 is particularly suitable for monitoring the pressure on the oil supply side of the heating system.

[0037] In general, the monitoring module of the granulator grease heating system proposed in this utility model mainly includes: a base 1, a positioning support rod 2, a vibration transmission slide plate 3, a mounting base plate 4, a vibration damping plate 5, and a sensor 6. (See also...) Figure 1 It shows the arrangement of the base 1, positioning support rod 2, vibration transmission slide plate 3, mounting base plate 4, damping plate 5 and sensor 6.

[0038] This utility model proposes a monitoring module for a granulator grease heating system. In use, one side of the slot 11 in the base 1 is clamped onto the flange 8, and the base 1 and flange 8 are connected by bolts. The vibration-transmitting slide plate 3 is fitted onto the positioning support rod 2. Based on the length of the heating system, the mounting base plate 4 is moved along the positioning support rod 2 into the mounting groove 71 of the bushing 7. A hexagonal screw 42 is screwed into the threaded hole 41. A damping plate 5 is placed on the side of the mounting base plate 4 near the oil supply port in the heating system. The damping plate 5 is fitted onto the hexagonal screw 42 through the waist hole 51. Tightening the hexagonal screw 42 controls the bottom of the sensor 6 to pass through the bushing 7 and enter the heating channel. This monitoring module can monitor the heating system in real time. The system controls the oil supply port pressure in the heating channel. If the pressure is too high, the oil output from the outlet will be smooth, and the output flow of the oil pump will be reduced. If the pressure is too low, the oil output from the outlet will be intermittent, and the output flow of the oil pump will be increased. If the pressure is too high, the oil output from the outlet will be intermittent, and the pellet mill program will be switched to increase the rotation speed of the pellet mill spindle. Two sections of shock-absorbing brackets are also set up. One section is equipped with a shock-absorbing plate 5 with a connecting waist hole 51 set design, which has a buffering effect. Compared with rigid fixation, it will not break the sensor 6. The second section is equipped with a vibration transmission plate 3, a positioning support rod 2 and a base 1, which transmits part of the vibration to the external bracket, reduces the axial stress acting on the threaded rod of the hexagonal bolt, and prevents the hexagonal bolt from loosening.

[0039] The aforementioned base 1 is bolted to one side of the pellet mill spindle box. The base 1 is triangular in shape, and a slot 11 is provided on one side of the base 1. The slot 11 is engaged with the flange 8 on the outside of the pellet mill spindle box. The base 1 is connected to the flange 8 by bolts. The triangular base 1, together with the flange slot design, forms a double positioning of engagement and bolts, which guides the vibration energy to the main body of the equipment through a rigid connection, thereby reducing the vibration amplitude at the sensor 6 end.

[0040] The aforementioned positioning support rod 2 is welded and clamped to one side of the base 1. A vibration transmission slide plate 3 is fitted on the side of the positioning support rod 2 away from the base 1. The vibration transmission slide plate 3 moves left and right along the positioning support rod 2. A mounting base plate 4 is welded to the bottom of the side of the vibration transmission slide plate 3 away from the positioning support rod 2. The mounting base plate 4 is T-shaped. The bottom of the mounting base plate 4 is clamped into the mounting groove 71 corresponding to the top of the bushing 7. The connection strength is improved by using clamping and bolts for double positioning and fixing. Threaded holes 41 are opened around the mounting base plate 4. The bottom of the threaded holes 41 passes through the mounting base plate 4 and is opened on the outside of the bushing 7. A hexagonal screw 42 is clamped in the threaded holes 41. The hexagonal screw 42 connects the mounting base plate 4 and the bushing 7. A weight reduction groove 31 is opened in the center of the vibration transmission slide plate 3.

[0041] The aforementioned shock-absorbing plate 5 is located on the left or right side of the top of the mounting base plate 4. A weight-reducing groove 31 is provided in the center of the vibration transmission slide plate 3. Waist holes 51 are provided on the front and rear sides of the side of the shock-absorbing plate 5 closest to the mounting base plate 4. The waist holes 51 are fitted on the outside of the hexagonal screw 42. The installation of the waist holes 51 can be used to adapt to the assembly tolerance. Secondly, it enables the shock-absorbing plate 5 to have connection strength while having the characteristics of flexible buffering under vibration.

[0042] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
