Description

Technical Field

[0001] The present application relates to the technical field of powder processing, and in particular to a flexible connection force detection device and a powder processing system. Background Art

[0002] At present, in the process of transporting or processing carbon black powder, soft connection (also known as soft connection, flexible connection) is often used at the connection port of dynamic / static equipment and pipeline. Its main function is to compensate for the displacement and stress caused by the vibration of equipment or pipeline.

[0003] During use, flexible connectors not only eliminate stress between dynamic and static equipment, but experienced technicians can also use their deformation to determine the state of material within the pipeline. For example, if a material blockage occurs, the flexible connector will expand significantly, while if the equipment is empty, the flexible connector will contract. However, excessive expansion and contraction can have negative effects. If the expansion force exceeds the force requirements of the flexible connector, it will break and leak, and in severe cases, it may cause a dust explosion. Excessive contraction may cause the buckle to loosen, and the risk of the flexible connector detaching easily due to the incoming material. However, this method relies solely on observing the state of the flexible connector, which is significantly affected by human factors, requires high technical skills, and is prone to inaccurate judgments.

[0036] Refer to the following Figures 1 to 3 The present invention describes a flexible connection force detection device and a powder processing system according to some embodiments of the present application.

[0037] Example 1

[0038] See also Figures 1 to 3 As shown, an embodiment of the present application provides a flexible connection force detection device, which is applied to a flexible connection pipe 13. The flexible connection force detection device includes: a receiving bag 1, a first guide member 2, a spring 3, a second guide member 4, a push-pull member 5, a push-pull force detection member 6, and a connecting member 7. The receiving bag 1 is hollow inside and open at both ends, and is used to be mounted on the outside of the flexible connection pipe 13 and can deform synchronously with the flexible connection pipe 13.

[0039] One open end of the receiving bag 1 is provided with a drawstring 103, which is used to tighten or enlarge the opening of the receiving bag 1, that is, the two ends of the receiving bag 1 are respectively formed with a first open end 101 and a second open end 102, and the second open end 102 is provided with a drawstring 103; the first guide member 2 and the spring 3 are sequentially arranged on the outside of the drawstring 103 along the direction away from the receiving bag 1, that is, the first guide member 2 and the spring 3 are sequentially arranged along the direction away from the receiving bag 1; the second guide member 4 is arranged on the side of the spring 3 away from the first guide member 2, and the second guide member 4 is connected to the drawstring 103, the first guide member 2, the spring 3 and the second guide member 4 are sequentially pressed against each other along the direction away from the receiving bag 1; the drawstring 103 can move relative to the first guide member 2 and the spring 3; the second guide member 4 can move following the drawstring 103 to compress or release the spring 3;

[0040] The first guide member 2 is fixed at the first target location, one end of the push-pull force detection member 6 is connected to the second guide member 4 through the push-pull member 5, and the other end of the push-pull force detection member 6 is fixed to the second target location through the connecting member 7, and the spring 3 is formed with a pre-tightening force. The push-pull force detection member 6 is used to detect the force applied to the soft connection pipeline 13.

[0041] According to the structure described above, the process of the flexible connection force detection device provided by the present application for monitoring the deformation state of the flexible connection pipeline 13 is as follows:

[0042] 1) Use a holding bag 1 with a tightening function to cover the outer layer of the flexible connecting pipe 13, and adjust the contraction and expansion function of the open end of the holding bag 1 through the drawstring 103 of the holding bag 1;

[0043] 2) A first guide member 2, a spring 3, a second guide member 4, a push-pull member 5, a push-pull force detection member 6, and a connecting member 7 are attached to the end of the drawstring 103 of the storage bag 1. After the drawstring 103 adjusts the storage bag 1 to fit snugly over the flexible connection pipe 13, the first guide member 2 is fixed to a first location, and the connecting member 7 is fixed to a second location, so that the spring 3 forms a certain preload force.

[0044] 3) When the soft connecting pipe 13 is not under stress, the push-pull force detection component 6 is cleared. When the soft connecting pipe 13 expands, the containing bag 1 will expand together, and then the drawstring 103 connected to the spring 3 will shrink and transmit a certain force to the push-pull force detection component 6 through the second guide component 4 and the push-pull component 5. The push-pull force detection component 6 will display a positive value (not limited to this, the push-pull force detection component 6 can also display a negative value). The greater the expansion force, the greater the tension value displayed by the push-pull force detection component 6; when the discharge speed of the soft connecting pipe 13 is greater than the feeding speed, due to the effect of negative pressure, The flexible connecting pipe 13 contracts, and the drawstring 103 of the containing bag 1 will be in a stress-free state. The spring 3 will generate a reverse thrust on the push-pull component 5, and the push-pull force detection component 6 will display a negative value (it should be noted that: when the containing bag 1 expands together with the flexible connecting pipe 13, the push-pull force detection component 6 displays a negative value, then when the flexible connecting pipe 13 contracts, the push-pull force detection component 6 displays a positive value, which is designed according to actual needs). Once this value exceeds the set upper limit, it indicates that the flexible connecting pipe 13 is abnormally stressed, and the equipment management personnel can directly observe it and deal with it as soon as possible.

[0045] It can be seen that the flexible connection force detection device provided by this application can scientifically and intuitively determine whether the flexible connection pipeline 13 is in a normal working state. It has low requirements for technical personnel, does not rely on the subjective judgment of technical personnel, and is less affected by human factors. It improves the accuracy of the judgment results, avoids misoperation, and ensures production efficiency.

[0046] In this embodiment, preferably, Figure 2 and Figure 3 As shown, the flexible connection force detection device further includes a fixing member 9, the first guide member 2 is disposed on the fixing member 9, and the fixing member 9 is fixedly connected to the first target location.

[0047] According to the structure described above, the fixing member 9 is used as a transition member to improve the convenience of assembly for the operator. Of course, it is also possible to not provide this fixing member 9, but to directly fix it to the first target ground by rationally designing the first guide member 2, which is selected according to actual needs.

[0048] In this embodiment, preferably, Figure 2 and Figure 3As shown, the fixing member 9 is detachably connected to the first target site via the first fastening member 8 .

[0049] As can be seen from the structure described above, the fixing member 9 is mounted on the first target location via the first fastening member 8, such as screws or bolts. This is a detachable connection method, facilitating subsequent disassembly and maintenance. Of course, the connection between the fixing member 9 and the first target location is not limited to being connected via the first fastening member 8. The connection can also be made by snap fastening, gluing, or welding, depending on actual needs.

[0050] In this embodiment, preferably, Figure 2 and Figure 3 As shown, the connecting member 7 is detachably connected to the second target site via a second fastening member 10 .

[0051] As can be seen from the structure described above, the connecting member 7 is mounted to the second destination via the second fastening member 10, such as screws or bolts. This is a detachable connection method, facilitating subsequent disassembly and maintenance. Of course, the connection between the connecting member 7 and the second destination is not limited to being connected via the second fastening member 10. Connections can also be made via snap fasteners, gluing, or welding, depending on actual needs.

[0052] In this embodiment, preferably, Figure 1 and Figure 3 As shown, an open end of the receiving bag 1 away from the drawstring 103 , ie, the first open end 101 , is used to be fixed on the end flange 131 of the flexible connecting pipe 13 .

[0053] According to the structure described above, securing one open end of the storage bag 1 to the end flange 131 of the flexible connecting pipe 13 prevents the storage bag 1 from shifting along the flexible connecting pipe 13, which could lead to inaccurate test results. Of course, the present invention is not limited to this. The open end of the storage bag 1, which is away from the drawstring 103, may not be secured to the end flange 131 of the flexible connecting pipe 13, but may be simply sleeved onto the outside of one end of the flexible connecting pipe 13, preferably conforming to or having an interference fit with the end of the flexible connecting pipe 13 before deformation, thereby ensuring that the storage bag 1 does not shift along the length of the flexible connecting pipe 13.

[0054] In this embodiment, preferably, Figure 3 As shown, the open end of the storage bag 1, which is away from the drawstring 103, is adapted to the undeformed flexible connecting pipe 13, making the assembly more coordinated and enabling the storage bag 1 to deform quickly and synchronously with the flexible connecting pipe 13. Of course, the open end of the storage bag 1, which is away from the drawstring 103, i.e., the first open end 101, and the undeformed flexible connecting pipe 13 can also adopt a clearance fit or an interference fit, depending on actual needs.

[0055] In addition, it should be noted that: when the containing bag 1 is assembled with the soft connecting pipe 13 before deformation, the drawstring 103 of the containing bag 1 is adapted to the length of the soft connecting pipe 13 along the length direction of the soft connecting pipe 13, that is, the containing bag 1 can completely wrap the soft connecting pipe 13, or the length of the containing bag 1 can be less than the length of the soft connecting pipe 13 along the length direction of the soft connecting pipe 13, that is, the containing bag 1 only wraps a part of the structure of the soft connecting pipe 13, etc. The specific selection is based on actual needs.

[0056] In this embodiment, preferably, the soft connection force detection device also includes an alarm controller (not shown in the figure), the push-pull force detection component 6 is a push-pull force sensor, and the push-pull force sensor is communicatively connected to the alarm controller, and when the value detected by the push-pull force detection component 6 exceeds a preset value, the alarm controller issues an alarm.

[0057] According to the structure described above, the present application adopts an alarm integrated with a control module. The push-pull force sensor transmits the detected data to the control module, and the control module analyzes the data. When the detected value exceeds its preset value, the alarm controller directly alarms and notifies the equipment management personnel to deal with it as soon as possible. There is no need for the equipment management personnel to constantly patrol the push-pull force detection component 6 to monitor the data thereon. The degree of automation is higher, the work intensity is reduced, and the work efficiency is improved. Moreover, the alarm controller is an existing component and is extremely easy to purchase.

[0058] It should be noted that the integrated structure using the alarm controller described above is not limited to other structures. For example, the flexible connection force detection device also includes an alarm and a controller. The push-pull force detection member 6 is a push-pull force sensor, and both the push-pull force sensor and the alarm are communicatively connected to the controller. When the value detected by the push-pull force detection member 6 exceeds a preset value, the alarm sounds an alarm. As can be seen, the controller and alarm are not integrated together, but are provided separately. Automatic alarm prompts can also be achieved. Controllers with this function are relatively common and will not be described in detail here.

[0059] In addition, it should be noted that: an alarm controller may not be provided, but manual inspection may be used to check the readings on the push-pull force detection component 6 to make a judgment, and the push-pull force detection component 6 is not limited to the use of push-pull force sensors, but may also use ordinary push-pull force meters, etc., depending on actual needs.

[0060] In this embodiment, preferably, Figure 2 and Figure 3 As shown, the receiving bag 1 is a net bag, which can be deformed along with the flexible connecting pipe 13 .

[0061] Furthermore, preferably, the net bag is a metal net bag, which can deform along with the flexible connecting pipe 13, is not easily damaged, and has a long service life. Of course, the material of the net bag is not limited to metal, and a plastic net bag or a cloth bag can also be used, and the specific selection is based on actual needs.

[0062] In this embodiment, preferably, Figure 2 and Figure 3 As shown, the push-pull member 5 is an immutable structural member, such as a rod or a block, etc., and its own immutability will not affect the detection results.

[0063] In this embodiment, preferably, Figure 2 and Figure 3 As shown, the connecting member 7 is L-shaped, and preferably, the connecting member 7 includes two perpendicular plates, one of which is convenient for connection with the second guide member 4, and one of which is convenient for connection with the second target location. Of course, the structure of the connecting member 7 is not limited to this, and can also be designed according to actual needs, such as a U-shaped plate or T-shaped plate with wings on both sides, etc.

[0064] In this embodiment, preferably, Figure 2 and Figure 3 As shown, the fixing member 9 is L-shaped or T-shaped, etc., which is convenient for matching with the first target, facilitating assembly, and improving assembly efficiency. Of course, the structure of the fixing member 9 is not limited to the above, and can also be designed according to actual needs.

[0065] In this embodiment, preferably, Figure 2 and Figure 3 As shown, the first guide member 2 is formed with a through hole, and the drawstring 103 is movably inserted into the through hole. The through hole serves to keep the drawstring 103 out of the way and avoid interference.

[0066] Example 2

[0067] See also Figure 3 As shown, the flexible connection force detection device in this embodiment is an improvement based on the first embodiment. The technical contents disclosed in the first embodiment will not be described repeatedly, and the contents disclosed in the first embodiment also belong to the contents disclosed in this embodiment.

[0068] In this embodiment, preferably, the soft connection force detection device further includes a pulley (not shown in the figure), and the pulley is arranged between the receiving bag 1 and the first guide member 2, and the drawstring 103 is wound around the pulley to change the direction of the drawstring 103.

[0069] According to the structure described above, when there is a large orientation difference between the first target location and the second target location and the receiving bag 1, and the transfer cannot be achieved by changing the shape or size of the connecting member 7 and the fixing member 9, it is necessary to provide the aforementioned pulley to change the direction of the drawstring 103, thereby facilitating the subsequent assembly, and the number of pulleys can be set to one or more according to actual needs. In particular, when multiple pulleys are set, multiple orientation changes can be performed, etc., and the scope of application is wider.

[0070] Example 3

[0071] See also Figure 3 As shown, embodiment three of the present application also provides a powder processing system, including the soft connection force detection device described in the above embodiment one or embodiment two, and therefore, has all the beneficial technical effects of the soft connection force detection device, and the same technical features and beneficial effects are no longer repeated.

[0072] In this embodiment, preferably, Figures 1 to 3 As shown, the powder processing system also includes a moving device 11, a static device 12 and a soft connecting pipe 13; wherein the soft connecting pipe 13 is connected between the moving device 11 and the static device 12; the containing bag 1 is arranged on the outside of the soft connecting pipe 13, and can deform synchronously with the soft connecting pipe 13; the first guide member 2 is fixed at the first target location, and the push-pull force detection member 6 is fixed at the second target location through the connecting member 7.

[0073] According to the structure described above, the powder processing system provided by the present application has a device for monitoring whether the deformation of the flexible connection pipeline 13 is out of tolerance, and can scientifically and intuitively judge whether the flexible connection pipeline 13 is in a normal working state. It has low requirements for technical personnel, does not rely on the subjective judgment of technical personnel, and is less affected by human factors. It improves the accuracy of the judgment results, avoids misoperation, and ensures production efficiency.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them.
