Description

Technical Field

[0001] The present invention relates to the technical field of thickeners, and in particular to a thickener detection structure with stable support. Background Art

[0002] The driving mechanism of the thickener needs to be equipped with a torque detection device to detect the torque. Combined with the on-site control cabinet, it can realize the protection of high torque alarm and automatic power-off and shutdown at ultra-high torque.

[0003] Conventional torque detection devices such as Figure 1 As shown, the reducer 101 is installed on the upper flange 102, and the torque is transmitted through the coupling 103, and the reducer 101 is limited and supported by the coupling 103. Since the upper flange 102 is unconstrained, the reducer 101 will rotate synchronously with the coupling 103 under normal circumstances. Using this characteristic, a pressure sensor 104 is set to fix the upper flange 102 to limit the upper flange 102. At the same time, the upper flange 102 applies pressure to the pressure sensor 104 through the force arm L. After the pressure sensor 104 detects the pressure, it outputs the detected pressure value to the PLC control cabinet. The program has been set in the PLC control cabinet to automatically calculate the real-time torque based on the detected pressure.

[0004] Although this structure achieves the effect of torque detection, it requires a support frame and a coupling, and requires precision machining. The transmission concentricity is ensured by the combination of the assembled components. Since there is a gap in the coupling and the torque transmission is not perfectly concentric during actual operation, the reducer will produce a slight swing. Since the pressure detected here is relatively small, a slight change in the operating condition will cause the detected pressure change range to be very large, and ultimately the output torque value will be seriously inconsistent with the operating condition, and it will be impossible to detect the torque, issue an alarm or shut down in time to protect the equipment. Summary of the invention

[0035] Embodiment 1

[0036] like Figure 2-5 As shown, an embodiment of the present invention provides a stable supporting thickener detection structure, including a first reducer 1 and a second reducer 2 that transmit to each other, an upper flange 3 and a lower flange 4 are respectively installed between the first reducer 1 and the second reducer 2, a lower support rod 5 is arranged on the lower flange 4, the lower support rod 5 includes an upper cross bar 501, a lower cross bar 502 and a vertical rod 503, one end of the vertical rod 503 is fixedly connected to the upper cross bar 501, and the other end of the vertical rod 503 is fixedly connected to the lower cross bar 502, a supporting device 6 is installed between the upper flange 3 and the lower flange 4, the supporting device 6 is used to stabilize the first reducer 1, a detection device 7 is installed between the first reducer 1 and the lower support rod 5, the detection device 7 is used to detect the torque between the first reducer 1 and the lower support rod 5.

[0037] like Figure 2 and Figure 5 As shown, in this embodiment, the upper cross bar 501, the lower cross bar 502 and the vertical bar 503 are all fixed by welding.

[0038] Such arrangement facilitates the fixation between the upper cross bar 501, the lower cross bar 502 and the vertical bar 503, and does not require the use of a large number of screws for fixation, so the assembly and fixation are very convenient.

[0039] like Figure 5 As shown, in this embodiment, a first reinforcement block 504 is fixedly connected between the vertical rod 503 and the upper cross bar 501 , and a second reinforcement block 505 is fixedly connected between the vertical rod 503 and the lower cross bar 502 .

[0040] The first reinforcing block 504 can improve the structural strength between the vertical rod 503 and the upper cross bar 501 , and the second reinforcing block 505 can improve the structural strength between the vertical rod 503 and the lower cross bar 502 , so as to better install the detection device 7 and support the first reducer 1 .

[0041] like Figure 2 As shown, in this embodiment, the number of the supporting devices 6 is three, and the three supporting devices 6 are evenly distributed around the circumference between the upper flange 3 and the lower flange 4 .

[0042] With this arrangement, only three supporting devices 6 are needed to stably support the first reducer 1 without uneven force.

[0043] like Figure 2 and Figure 3 As shown, in this embodiment, the supporting device 6 includes a lower fixed block 601, on which a fixing rod 602 is adjustably provided, a bracket 603 is installed on the top of the fixing rod 602, and a supporting bearing 604 is rotatably connected to the bracket 603. The lower fixed block 601 is welded and fixed to the lower flange 4, and the outer surface of the supporting bearing 604 is in contact with the lower surface of the upper flange 3.

[0044] Such arrangement makes it easier to fix the lower fixing block 601 to the lower flange 4, and the welding fixation is more secure, thus preventing the phenomenon of falling off.

[0046] When installing in this way, the bottom end of the fixing rod 602 is passed through the mounting hole 605 and supports the bracket 603 to prevent rotation, and then the first fixing nut 606 is rotated. At this time, the fixing rod 602 drives the bracket 603 and the support bearing 604 to move upward until the support bearing 604 contacts the lower surface of the upper flange 3 for support, and then the second fixing nut 607 is tightened. At this time, the fixing rod 602 can be firmly fixed to the lower fixing block 601, so that the support device 6 supports the first reducer 1.

[0047] like Figure 3 and Figure 4 As shown, in this embodiment, a threaded hole 608 is formed at the bottom end of the bracket 603 , and the top end of the fixing rod 602 is threadedly connected in the threaded hole 608 and is threadedly connected with a third fixing nut 609 .

[0048] When installing in this way, the top end of the fixing rod 602 is threadedly connected to the threaded hole 608, and then the third fixing nut 609 is tightened, so that the fixing rod 602 and the bracket 603 can be firmly fixed together.

[0049] like Figure 3 and Figure 4 As shown, in this embodiment, a mounting groove 610 is provided at the top of the bracket 603, and the support bearing 604 is arranged in the mounting groove 610. A pin 611 is provided on one side of the mounting groove 610. One end of the pin 611 passes through the bracket 603 and the support bearing 604 and is threadedly connected with a fourth fixing nut 612. The support bearing 604 is rotatably connected to the pin 611.

[0050] The support bearing 604 is rotatably mounted on the bracket 603 via the pin 611 , thereby better supporting the first reducer 1 .

[0051] In this embodiment, the detection device 7 is a pressure sensor.

[0052] In this way, when the first reducer 1 is working, pressure is applied to the pressure sensor. After the pressure sensor detects the pressure, the detected pressure value is output to the PLC control cabinet. The program has been set in the PLC control cabinet to automatically calculate the real-time torque based on the detected pressure. When the set torque is reached, the alarm or shutdown is timely to protect the safety of the equipment.

[0053] The technical solution provided by the present invention is that during installation, the upper cross bar 501, the lower cross bar 502 and the vertical bar 503 are welded and fixed together, and reinforced by the first reinforcement block 504 and the second reinforcement block 505, and then the lower fixing block 601 is fixed together with the lower flange 4, and then the lower fixing block 601 and the lower flange 4 are fixed together by welding, and the support bearing 604 is rotatably installed on the bracket 603 through the pin 611, and then the top end of the fixing rod 602 is threadedly connected with the threaded hole 608, and then the third fixing nut 609 is tightened, at this time, the fixing rod 602 and the bracket 603 can be firmly fixed together, and then the bottom end of the fixing rod 602 passes through the installation hole 605 and supports the bracket 603 To prevent rotation, the first fixing nut 606 is rotated. At this time, the fixing rod 602 drives the bracket 603 and the support bearing 604 to move upward until the support bearing 604 contacts the lower surface of the upper flange 3 for support, and then the second fixing nut 607 is tightened. At this time, the fixing rod 602 can be firmly fixed to the lower fixing block 601, so that the support device 6 supports the flange. During operation, it can be installed on any support device 6 at any time according to needs. At the same time, it is convenient to adjust. It can perform a certain degree of height adjustment according to different situations to achieve the purpose of stably supporting the flange, so that the output torque value is consistent with the working conditions, the torque can be better detected, and the alarm or shutdown can be carried out in time to protect the equipment.

[0055] The similarities between this embodiment and the first embodiment are not repeated here. The difference between this embodiment and the first embodiment is that Figure 5 and Figure 6 As shown, the supporting device 6 includes a supporting frame 621, a deep groove ball bearing 622 and a sleeve 623. The bottom end of the supporting frame 621 is fixedly connected to the lower flange 4, the deep groove ball bearing 622 is rotatably mounted on the top of the supporting frame 621, the sleeve 623 is fixedly connected to the outer surface of the deep groove ball bearing 622, and the left side of the upper flange 3 is fixedly connected to an upper supporting rod 624, and the sleeve 623 is fixedly connected to the upper supporting rod 624 through a pin 625.
