Description

Technical Field

[0001] The invention belongs to the technical field of conveyor belt detection, and in particular relates to a conveyor belt deviation detection device and a vacuum belt dehydrator. Background Art

[0002] The conveyor belt of the vacuum belt dehydrator may deviate during operation. If the deviation continues, it will cause wear of the conveyor belt, affect the conveying efficiency, and even cause safety hazards. In the related technology, the deviation switch is used to detect whether the conveyor belt is deviated, so as to adjust the conveyor belt in time according to the feedback signal of the deviation switch.

[0003] However, since the installation position of the deviation switch is close to the conveyor belt, when the vacuum belt dehydrator is running, the conveyor belt flushing water continuously drips onto the deviation switch, which affects the service life of the switch and often causes the signal to be mis-sent, resulting in equipment tripping. Summary of the invention

[0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. To this end, an embodiment of the present invention provides a conveyor belt deviation detection device, which can improve the accuracy and service life of signal feedback.

[0005] The embodiment of the present invention further provides a vacuum belt dehydrator.

[0006] The conveyor belt deviation detection device of the embodiment of the present invention includes: a mounting frame, which is arranged on the side of the conveying direction of the conveyor belt; a detection member, which is arranged on the mounting frame; a transmission member, which includes a connecting section and a contact section, one end of the connecting section is connected to the detection member, and the end of the connecting section facing away from the detection member extends toward the conveyor belt by a preset distance, the contact section is connected to the end of the connecting section facing away from the detection member and is arranged opposite to the conveyor belt, and the extension direction of the contact section is arranged at an angle to the conveying plane of the conveyor belt.

[0007] It is understandable that when the conveyor belt deviates, the conveyor belt abuts against the contact section, and the transmission member is displaced through the contact section. When the displacement of the transmission member reaches a certain value, the transmission member triggers the detection member. By setting the transmission member, the detection member can be set at a position far away from the conveyor belt, thereby preventing water on the conveyor belt from splashing onto the detection member, which is conducive to the stable and reliable operation of the detection member and improving the accuracy of the detection results. In addition, the detection member is far away from the conveyor belt, which does not affect the inspection and maintenance of the detection member during the operation of the conveyor belt, which is conducive to improving work efficiency. In addition, the extension direction of the contact section is set at an angle with the conveying plane of the conveyor belt, so that even if the conveyor belt deviates in the case of vertical jump, it can hit the contact section to ensure the accuracy of the detection results.

[0008] In this embodiment, the mounting frame includes: a mounting plate, the mounting plate having a connecting groove, the connecting groove extending along the width direction of the conveyor belt, and the mounting plate is fixed by a connecting member passing through the connecting groove; a supporting member, the supporting member is arranged on the mounting plate, and a positioning space is formed between the supporting member and the mounting plate, and the detection member is limited to the positioning space.

[0009] In this embodiment, the supporting member is U-shaped, and both ends of the supporting member are connected to the mounting plate.

[0010] In this embodiment, the conveyor belt deviation detection device further includes a roller, and the roller is arranged on the contact segment and is rotatable relative to the contact segment.

[0011] In this embodiment, the roller includes a cylindrical section and conical sections located at both ends of the cylindrical section. The diameter of the conical ends at both ends of the roller gradually decreases from the end away from the cylindrical section to the end close to the cylindrical section, and the height of the cylindrical section matches the height of the conveyor belt.

[0012] In this embodiment, the transmission member is L-shaped.

[0013] In this embodiment, the conveyor belt deviation detection device further includes a support member, wherein the support member is disposed between the detection member and the contact section, the support member has a guide hole, and the connecting section passes through the guide hole and is movable relative to the support member.

[0014] In this embodiment, the conveyor belt deviation detection device also includes a linear bearing, and the linear bearing is arranged in the guide hole, and the connecting section passes through the linear bearing.

[0015] The vacuum belt dehydrator in this embodiment includes a conveyor belt and the above-mentioned conveyor belt deviation detection device, and the conveyor belt deviation detection device is arranged on the side of the conveyor belt.

[0016] In this embodiment, the conveyor belt running detection device is arranged on both sides of the conveyor belt. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0025] In this embodiment, if Figures 1 to 3 As shown in the figure, X direction is the conveying direction of the conveyor belt 100, Y is the width direction of the conveyor belt 100, and the conveyor belt deviation detection device includes a mounting frame 1, a detection member 2 and a transmission member 3. The mounting frame 1 is arranged on the side of the conveying direction of the conveyor belt 100; the detection member 2 is arranged on the mounting frame 1; the transmission member 3 includes a connecting section 31 and a contact section 32, one end of the connecting section 31 is connected to the detection member 2, and the end of the connecting section 31 away from the detection member 2 extends toward the conveyor belt 100 by a preset distance, the contact section 32 is connected to the end of the connecting section 31 away from the detection member 2 and is arranged opposite to the conveyor belt 100, and the extension direction of the contact section 32 is arranged at an angle to the conveying plane of the conveyor belt 100.

[0026] Specifically, the mounting frame 1 can be connected to an equipment frame on the side of the conveyor belt 100, or fixed on the ground. The specific connection method of the mounting frame 1 can be adaptively adjusted according to the actual site environment and is not limited here.

[0027] For example, the detection member 2 is a deviation switch, and the connecting section 31 is connected to the rotating wheel of the deviation switch. When the connecting section 31 drives the rotating wheel to deflect, an alarm signal can be triggered. When the connecting section 31 is reset, the rotating wheel resets itself.

[0028] The extending direction of the contact segment 32 is set at an angle to the conveying plane of the conveyor belt 100, which means that in the projection in the width direction of the conveyor belt 100, the conveying direction of the conveyor belt 100 and the extending direction of the contact segment 32 are set at an angle. Figure 3 As shown, the angle between the conveying direction of the conveyor belt 100 and the extension direction of the contact segment 32 is A, and A is 90°, so that the conveyor belt 100 can hit the contact segment 32 even when it deviates due to vertical jumping. The angle between the conveying direction of the conveyor belt 100 and the extension direction of the contact segment 32 can be adjusted as needed and is not limited here.

[0029] It is understandable that when the conveyor belt 100 deviates, the conveyor belt 100 abuts against the contact section 32, and the transmission member 3 is displaced through the contact section 32. When the displacement of the transmission member 3 reaches a certain value, the transmission member 3 triggers the detection member 2. By setting the transmission member 3, the detection member 2 can be set at a position far away from the conveyor belt 100, so as to avoid water on the conveyor belt 100 splashing onto the detection member 2, which is conducive to the stable and reliable operation of the detection member 2 and improves the accuracy of the detection result. In addition, the detection member 2 is far away from the conveyor belt 100, which does not affect the inspection and maintenance of the detection member 2 during the operation of the conveyor belt 100, which is conducive to improving work efficiency. In addition, the extension direction of the contact section 32 is set at an angle with the conveying plane of the conveyor belt 100, so that even if the conveyor belt 100 deviates in the case of vertical jump, it can hit the contact section 32 to ensure the accuracy of the detection result.

[0030] In this embodiment, if Figure 1 As shown, the transmission member 3 is L-shaped.

[0031] It can be understood that the transmission member 3 is configured to be L-shaped so that the connection section 31 and the contact section 32 of the transmission member 3 can be integrally formed by bending, which is convenient for processing.

[0032] In this embodiment, if Figure 3 As shown, the mounting frame 1 includes a mounting plate and a supporting member, the mounting plate has a connecting groove 101, the connecting groove 101 extends along the width direction of the conveyor belt 100, and the mounting plate is fixed by a connecting member passing through the connecting groove 101; the supporting member is arranged on the mounting plate, and a positioning space is formed between the supporting member and the mounting plate, and the detection member 2 is limited in the positioning space.

[0033] For example, a plurality of connection slots 101 may be provided on the mounting plate, and the plurality of connection slots 101 are arranged in parallel and spaced apart, and a connection piece is inserted into each connection slot 101. By providing a plurality of connection slots 101, the mounting plate can be fixed by a plurality of connection pieces, thereby improving the stability of the connection of the mounting plate. The connection piece may be a screw, and the mounting plate can be fixed when the screw is tightened, and the mounting plate can be moved when the screw is loosened. The specific connection method of the screw is a conventional prior art and will not be described in detail here.

[0034] Specifically, after the detection member 2 is installed in the positioning space, it is fixed on the mounting plate through a connecting member, so that the detection member 2 can be stably fixed. The connecting member for fixing the detection member 2 can be a screw, and a connecting hole is provided on the detection member 2. The detection member 2 is fixed to the supporting member or the mounting plate through the connecting member. When the detection member 2 is limited in the positioning space, the detection part of the detection member 2 protrudes from the positioning space, so as to avoid interference of the mounting frame 1 with the detection of the detection member 2.

[0035] The mounting frame 1 in this embodiment is provided with a connection groove 101 on its mounting plate, so that the mounting plate can be moved relative to the connecting member through the connection groove 101 when the connecting member is loosened. The extension direction of the connection groove 101 is consistent with the width direction of the conveyor belt 100, so that the mounting plate can be moved along the width direction of the conveyor belt 100, thereby adjusting the distance between the conveyor belt 100 and the detection member 2 through the mounting plate, so that the detection member 2 is located in a range away from water splashing from the conveyor belt 100, thereby better protecting the detection member 2. A positioning space is formed between the supporting member and the mounting plate, and the detection member 2 can be limited by the positioning space, so that the detection member 2 is easier to install.

[0036] In this embodiment, the supporting member is U-shaped, and both ends of the supporting member are connected to the mounting plate.

[0037] Specifically, the supporting member is located below the mounting plate, and both ends of the supporting member are connected to the bottom of the mounting plate. The supporting member and the mounting plate can be connected by welding. Of course, the supporting member and the mounting plate can also be connected by other means, which are not limited here.

[0038] In this embodiment, by arranging the supporting member into a U-shape, a positioning space can be formed between the supporting member and the mounting plate.

[0039] In this embodiment, if Figure 4 As shown, the conveyor belt deviation detection device further includes a roller 5 , which is disposed on the contact segment 32 and rotatable relative to the contact segment 32 .

[0040] Specifically, a bearing may be provided between the roller 5 and the contact section 32 to reduce the friction force when the roller 5 rotates relative to the contact section 32 , so that the roller 5 can rotate more smoothly.

[0041] It can be understood that by arranging the roller 5 on the contact section 32 , when the conveyor belt 100 deviates and contacts the roller 5 , the friction between the conveyor belt 100 and the roller 5 can be reduced, thereby reducing the wear of the conveyor belt 100 .

[0042] In this embodiment, if Figure 4 As shown, the roller 5 includes a cylindrical section and conical sections at both ends of the cylindrical section. The diameter of the conical ends at both ends of the roller 5 gradually decreases from the end away from the cylindrical section to the end close to the cylindrical section. The height of the cylindrical section matches the height of the conveyor belt 100.

[0043] Specifically, the junction of the conical section and the cylindrical section is transitioned through an arc section, so that the conveyor belt 100 can move smoothly between the conical section and the cylindrical section. Further, the middle of the cylindrical section in the vertical direction is at the same height as the conveyor belt 100 in a stationary state.

[0044] It should be noted that the two ends of the roller 5 are set as conical sections, and the middle part is set as a cylindrical section. When the conveyor belt 100 bounces vertically, the conveyor belt 100 can be blocked by the conical sections at both ends of the roller, so that the conveyor belt 100 abuts against the cylindrical section. The height of the cylindrical section matches the height of the conveyor belt 100, so that the displacement of the conveyor belt 100 when it is offset can be more accurately transmitted to the detection member 2 through the cylindrical section through the transmission member 3.

[0045] In this embodiment, if Figure 1 As shown, the conveyor belt deviation detection device also includes a support member 4, which is arranged between the detection member 2 and the contact section 32. The support member 4 has a guide hole 41, and the connecting section 31 passes through the guide hole 41 and is movable relative to the support member 4.

[0046] For example, the support member 4 may be an equipment frame on the side of the conveyor belt 100, or may be a structure separately provided for supporting the transfer member 3. The specific setting method of the support member 4 may be provided according to the on-site environment and is not limited here.

[0047] It is understandable that by providing a support member 4 and providing a guide hole 41 on the support member 4, the transfer member 3 is supported and guided, which can prevent the transfer member 3 from swinging and allow the conveyor belt 100 to move horizontally along the deviation direction, which is beneficial to ensure the accuracy of the detection result.

[0048] In this embodiment, the conveyor belt deviation detection device further includes a linear bearing (not shown in the figure), the linear bearing is arranged in the guide hole 41, and the connecting section 31 passes through the linear bearing.

[0049] It can be understood that by setting a linear bearing in the guide hole 41 and passing the connecting section 31 through the linear bearing, the friction between the connecting section 31 and the linear bearing can be reduced, so that the displacement of the conveyor belt 100 can be more accurately transmitted to the detection member 2 through the transmission member 3, which is beneficial to improving the accuracy of the detection result.

[0050] The vacuum belt dehydrator in this embodiment includes a conveyor belt 100 and the above-mentioned conveyor belt deviation detection device, and the conveyor belt deviation detection device is arranged on the side of the conveyor belt 100.

[0051] The vacuum belt dehydrator in this embodiment is provided with the above-mentioned conveyor belt deviation detection device. When the conveyor belt 100 of the vacuum belt dehydrator dehydrates, the conveyor belt 100 causes the transmission member 3 to be displaced through the contact section 32. When the displacement of the transmission member 3 reaches a certain value, the transmission member 3 triggers the detection member 2. By providing the transmission member 3, the detection member 2 can be set at a position far away from the conveyor belt 100, thereby preventing water on the conveyor belt 100 from splashing onto the detection member 2, which is conducive to the stable and reliable operation of the detection member 2 and improves the accuracy of the detection result. In addition, the detection member 2 is far away from the conveyor belt 100, and during the operation of the conveyor belt 100, it does not affect the inspection and maintenance of the detection member 2, which is conducive to improving work efficiency.

[0052] In this embodiment, conveyor belt 100 running detection devices are provided on both sides of the conveyor belt 100 .

[0053] It is understandable that since the deviation direction of the conveyor belt 100 is uncertain during the conveying process, by arranging conveyor belt deviation detection devices on both sides of the conveyor belt 100, when the conveyor belt deviates in any direction, it can be detected by the conveyor belt deviation detection device, so as to facilitate timely adjustment of the conveyor belt 100.
