Description

Technical Field

[0001] This utility model relates to the field of early warning device technology, and in particular to a wire-contraction type early warning device for monitoring pulp dust concentration. Background Technology

[0002] When monitoring dust concentration in pulp workshops, a concentration monitoring and early warning device and a wire-retractable early warning device are usually used in conjunction to monitor and warn of dust concentration. Generally, the wire-retractable early warning device is installed near the fixed support point of the dust collector's outlet duct. During the operation of the dust collector, the outlet duct is affected by airflow impact and vibration. If the support point becomes loose or damaged, it may cause the duct to deform or break, affecting the dust removal effect or even causing a safety accident. The early warning device installed here can monitor the status changes of the support point and detect potential problems in advance. When using a wire-retracting warning device, warnings are generally issued by checking whether the wire is pulled, slack, or broken. When the wire is slack or broken, it needs to be replaced. When replacing the wire, the power must be cut off first, and then the old wire on the dust removal equipment must be removed, the new wire installed, and the device tested. Because the warning frequency of the wire is high, the wear and tear on the wire is significant, which can easily lead to waste of wire resources. In addition, the frequent replacement of the wire by the staff increases the workload of the staff and reduces work efficiency. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Example: This example provides a wire-contraction type early warning device for monitoring pulp dust concentration. See [link to example]. Figure 1-5 The device includes a main body 1, a tying machine body 4 at the upper end of the main body 1, a guide rope 5 wound around the outside of the tying machine body 4, and an installation component 2 and a fixing component 3 at the end of the guide rope 5 away from the tying machine body 4. The installation component 2 includes a U-shaped plate 205 at the end of the guide rope 5 away from the tying machine body 4. The U-shaped plate 205 is U-shaped, and an installation plate 201 is provided on the inner side of the U-shaped plate 205. A pair of symmetrical locking blocks 202 are slidably disposed inside the installation plate 201. Spring 204, the model of spring 204 can be GB / T2098-2009, spring 204 is used to provide elastic force for the locking block 202, and is set between a pair of locking blocks 202. The end of the locking block 202 away from spring 204 is in an inclined arc shape to facilitate sliding in the slot. A bag dust collector 6 is provided on one side of the device body 1, and an air outlet 7 is provided on the side of the bag dust collector 6 near the device body 1. The top surface of the mounting plate 201 has a circular hole, and a pair of sliding grooves 207 are formed in the circular hole. A pair of protrusions 203 are fixed on the outer side of each locking block 202. Each pair of protrusions 203 slides in the corresponding sliding groove 207. The protrusions 203 are used to provide stability for the locking block 202 and keep the locking block 202 horizontal when moving. The two side walls of the U-shaped plate 205 have slots, and a pair of locking blocks 202 are set in the corresponding slots. The slots are inclined. The outer surface of the mounting plate 201 is attached to the inner surface of the U-shaped plate 205. Rectangular plates 206 are fixed on both sides of the U-shaped plate 205. The rectangular plates 206 make it easier for workers to grasp the U-shaped plate 205 and make the installation of the U-shaped plate 205 more convenient. A wire body 8 is inserted through the lower surface of the U-shaped plate 205 and the middle of the lower locking block 202. A sensor 208 is provided at one end of the wire body 8. The sensor 208 is used to monitor the tension of the lead rope 5. The sensor 208 is located inside the spring 204. A controller is provided at the end of the wire body 8 away from the sensor 208. The controller is located inside the device body 1. When the tension of the lead rope 5 increases, the mounting plate 201 and the U-shaped plate 205 generate opposite pulling forces, causing a pair of locking blocks 202 to move outward. Under the action of the spring 204, the pair of locking blocks 202 move in a centered manner, causing the sensor 208 to be squeezed. Since one end of the sensor 208 is electrically connected to the wire body 8 and the other end of the wire body 8 is electrically connected to the controller (not shown in the figure), the sensor 208 provides a signal to the controller through the wire body 8. The controller issues an alarm through the sound alarm and the sound and light alarm (not shown in the figure) inside the device body 1. This utility model discloses a wire-retracting early warning device for monitoring pulp dust concentration. By setting the mounting component 2, it achieves the functions of preventing wire breakage and facilitating monitoring and early warning. If the mounting plate 201 and U-shaped plate 205 remain taut under the action of the guide rope 5 and do not squeeze the sensor 208, there will be no abnormality in the early warning. If the mounting plate 201 and U-shaped plate 205 generate opposite pulling forces under the action of the guide rope 5, the locking block 202 moves in the center, causing the sensor 208 to be squeezed by the locking block 202. Then, the sensor 208 provides a signal to the controller through the wire body 8. The controller issues an alarm through the sound alarm and audible and visual alarm inside the device body 1, which facilitates the immediate instruction of the maintenance team to repair the faulty equipment. The mounting plate 201 and U-shaped plate 205 can prevent the wire from loosening or breaking, so that the equipment will not pull the wire apart, reducing wire loss and reducing wire resource waste.

[0016] In the specific implementation process, such as Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the fixing component 3 includes multiple fixing plates 301, and there is more than one fixing plate 301. The fixing plate 301 is in the shape of an annular barrel. A fixing plate 301 is fixed at one end of the mounting plate 201 near the guide rope 5, and a fixing plate 301 is fixed at one end of the U-shaped plate 205 away from the guide rope 5. A cross groove is opened at one end of the fixing plate 301, which facilitates the insertion of the guide rope 5. An annular plate 302 is threaded on the outer side of each fixing plate 301. The inner diameter of the annular plate 302 is equal to the outer diameter of the fixing plate 301. When the annular plate 302 is not used, the annular plate 302 is located on the side of the fixing plate 301 away from the cross groove. When the annular plate 302 is used, since the outer side of the fixing plate 301 near the cross groove has a threaded groove, the annular plate 302 rotates into the threaded groove, so that the annular plate 302 can clamp the guide rope 5 located inside the fixing plate 301. The inner side of the fixing plate 301 is provided with anti-slip texture. The anti-slip texture can increase the friction between the inner side of the fixing plate 301 and the guide rope 5, so that the guide rope 5 can be fixed more tightly in the fixing plate 301, and avoid the device body 1 from generating false alarms due to the guide rope 5 falling off the fixing plate 301. The guide rope 5 is set in the fixing plate 301. There is more than one guide rope 5. Another guide rope 5 is set in the fixing plate 301 located at one end of the U-shaped plate 205. The end of the other guide rope 5 away from the U-shaped plate 205 is set with a fixing plate 301. The guide rope 5 is not a single segment. See Figure 1-5 The position of the fixing plate 301 on the main body 6 of the bag filter shown in the figure is only one of them. The fixing plate 301 can be installed on the filter bag frame, pipe flange, winding equipment (not shown in the figure) and other fault-prone parts, and the mounting parts 2 are installed accordingly. The guide rope 5 is always in a taut state, which can focus on monitoring mechanical displacement and tension abnormalities and avoid being affected by dust. This utility model discloses a wire-retracting early warning device for monitoring pulp dust concentration. By setting a fixing component 3, it enables rapid replacement of the guide rope 5. When the guide rope 5 needs to be replaced, the annular plate 302 on the outside of the fixing plate 301 is rotated to move the annular plate 302 to the outside of the guide rope 5. The old guide rope 5 is taken out from the fixing plate 301, and the new guide rope 5 is inserted into the fixing plate 301. The annular plate 302 is then rotated to move to the outside of the guide rope 5, clamping the guide rope 5. This facilitates rapid replacement of the guide rope 5 by the staff and improves work efficiency.

[0017] Specifically, the working principle and operation method of this utility model are as follows: In specific operations, a fixed plate 301 is installed in a location on the bag filter 6 that is easy to monitor. One end of a guide rope 5 is inserted into the fixed plate 301. The annular plate 302 on the outside of the fixed plate 301 is rotated to clamp one end of the guide rope 5. Then the operation is as follows. Step 1: Insert the other end of a section of the guide rope 5 into the fixing plate 301 located at one end of the U-shaped plate 205, rotate the annular plate 302 on the outside of the fixing plate 301 to clamp the other end of the guide rope 5, insert the guide rope 5 wound around the outside of the main body 4 into the fixing plate 301 located at one end of the mounting plate 201, rotate the annular plate 302 on the outside of the fixing plate 301 to clamp the guide rope 5, and ensure that the guide rope 5 is always in a taut state. Step 2: When the guide rope 5 is pulled, the mounting plate 201 and the U-shaped plate 205 generate opposite pulling forces. Under the action of the extension force of the spring 204, the pair of locking blocks 202 move in the center, causing the sensor 208 to be squeezed by the locking blocks 202. When the pulling force of the guide rope disappears, the spring 204 rebounds, causing the locking blocks 202 to engage in the slot. At this time, the sensor 208 is in an unpressed state. Step 3: When it is necessary to replace the guide rope 5, rotate the annular plate 302 on the outside of the fixing plate 301 to move the annular plate 302 to the outside of the guide rope 5, remove the old guide rope 5 from the fixing plate 301, insert the new guide rope 5 into the fixing plate 301, rotate the annular plate 302 to move the annular plate 302 to the outside of the guide rope 5, so that the guide rope 5 is clamped.
