Description

Technical Field

[0001] The utility model relates to the technical field of anti-blocking of belt conveyors, in particular to a device for preventing large blocks of sintering production belts. Background Art

[0002] In the sintering production process, the materials are evenly mixed and granulated by the mixer and then transported to the belt conveyor through the mixer discharge port for transportation. However, during the material processing in the mixer, the inner wall of the drum is prone to material accumulation and ring formation, causing the material to be compacted on the drum wall. When the compacted material falls off the drum, larger compacted materials may get stuck in the belt conveyor discharge port, causing material blockage. For this reason, the belt conveyor needs to be equipped with a device to prevent large pieces of material from entering the discharge port.

[0003] In the related art, a Chinese patent with authorization announcement number CN215624891U provides a chain control device to prevent large pieces of material from damaging the conveyor, which includes a group of brackets, a cross bar is rotatably connected between the brackets, an arc plate is installed at the bottom of the cross bar, a travel switch is installed on the front side of one of the brackets, and a touch plate is installed at the bottom of the cross bar near the travel switch. When the belt drives the material to move, when a large piece of material in the material touches the arc plate, the arc plate is forced to drive the cross bar to rotate, and the rotation of the cross bar drives the touch plate to squeeze the travel switch, so that the belt stops running, reducing the situation where large pieces of material enter the unloading port of the belt conveyor.

[0004] In the process of implementing this application, the inventors found that there are at least the following problems in this technology: when the distance between the top of the arc plate and the belt is smaller than the maximum size of the bulk material, the bulk material will be intercepted by the cross bar, making it difficult for the bulk material to push the arc plate due to the restriction of the cross bar. Although the bulk material is trapped on the belt and is not easy to enter the unloading port of the belt conveyor, the normal operation of the belt causes the bulk material to rub against the belt for a long time, which can easily cause the belt to be damaged. If the height of the arc plate is increased, the above problems can be avoided, but the volume and cost of the device will be increased at the same time. Utility Model Content

[0005] In order to reduce the wear of the belt by large pieces of material and prevent the large pieces of material from being stuck in the unloading port of the belt conveyor, the present application provides a sintering production belt anti-large piece device.

[0006] The present application provides a sintering production belt anti-large block device adopts the following technical solution:

[0007] A sintering production belt anti-large block device comprises a group of brackets, one of which is provided with a pressure sensor, a trigger rod is slidably provided on the bracket, a trigger block is fixedly provided on the back of the trigger rod, the trigger block is used to abut against the pressure sensor on the side facing the pressure sensor, a material blocking cylinder is provided between the trigger rods, and the material blocking cylinder is used to abut against large pieces of material on the side away from the pressure sensor.

[0008] By adopting the above technical scheme, in the process of material movement driven by the belt, when large pieces of material in the material touch the side of the material blocking barrel away from the pressure sensor, since the distance between the bottom of the material blocking barrel and the belt is smaller than the size of the large piece of material, the material blocking barrel is pushed by the large piece of material, causing the material blocking barrel to drive the trigger rod to move horizontally along the length direction of the bracket. When the trigger rod drives the trigger block to move horizontally until it abuts against the pressure sensor, the belt stops running, reducing the situation where large pieces of material enter the unloading port of the belt conveyor. Although the large piece of material will be intercepted by the material blocking barrel, the material blocking barrel will move with the large piece of material, making it difficult for the large piece of material and the belt to move relative to each other, reducing the situation where the belt is worn by the large piece of material.

[0009] Preferably, the outer wall of the material blocking barrel is provided with an arc surface, the end diameter of the material blocking barrel is larger than the end diameter of the trigger rod, the material blocking barrel and the trigger rod are coaxially arranged, and the end wall of the material blocking barrel is rotatably connected to the opposite surface of the trigger rod.

[0010] By adopting the above technical scheme, when small pieces of material pass between the belt and the material blocking barrel, the material blocking barrel rotates to reduce the mutual friction between the material blocking barrel and the material. At the same time, the material blocking barrel and the trigger rod are coaxially arranged so that during the rotation of the material blocking barrel, the distance between the bottom of the material blocking barrel and the bottom of the belt is always maintained unchanged, and the arc surface is arranged according to the curvature of the belt to reduce the situation where the two sides of the belt are too close to the material blocking barrel, thereby facilitating the passage of small pieces of material between the belt and the material blocking barrel.

[0012] By adopting the above technical solution, the trigger rod abuts between the lower guide rod and the upper guide rod, so that the trigger rod moves along the length direction of the bracket, so that the trigger rod drives the trigger block to move horizontally until it abuts against the pressure sensor.

[0013] Preferably, a limit plate is sleeved on the trigger rod, the limit plate is fixedly connected to the trigger rod, the back surface of the limit plate abuts against the opposite surface of the lower guide rod, and the back surface of the limit plate abuts against the opposite surface of the upper guide rod.

[0014] By adopting the above technical solution, when the trigger rod moves along the length direction of the bracket, the opposite surfaces of the lower guide rod and the upper guide rod abut against the back surfaces of the limit plate, so that the trigger rod is not easy to move along the width direction of the bracket.

[0015] Preferably, the trigger rod is cylindrical, and the trigger rod is rollingly arranged between the upper guide rod and the lower guide rod.

[0016] By adopting the above technical solution, when the trigger rod moves along the length direction of the bracket, the trigger rod rotates, thereby causing the trigger rod to roll between the lower guide rod and the upper guide rod, so that the lower guide rod and the upper guide rod form rolling friction with the trigger rod, thereby reducing the mutual wear between the lower guide rod and the trigger rod, and reducing the mutual wear between the upper guide rod and the trigger rod.

[0017] Preferably, the trigger block is cylindrical, the end diameter of the trigger block is larger than the end diameter of the trigger rod, the trigger block and the trigger rod are coaxially arranged, and the opposite surface of the trigger block is rotatably connected to the opposite back surface of the trigger rod.

[0018] By adopting the above technical solution, the distance between the outer wall of the trigger block and the axis of the trigger rod is always consistent, which facilitates the abutment between the trigger block and the pressure sensor.

[0019] Preferably, the pressure sensor is fixedly arranged on a side of one of the upper guide rods away from the other upper guide rod, and the pressure sensor is abutted by the trigger block.

[0020] By adopting the above technical solution, the pressure sensor and the material on the belt are blocked by the upper guide rod, thereby reducing the situation where the material splashes and collides with the pressure sensor.

[0021] Preferably, a rubber layer is fixedly provided on the side wall of the trigger block, and the rubber layer is used for contacting with the pressure sensor.

[0022] By adopting the above technical solution, the rubber layer buffers the instantaneous force between the trigger block and the pressure sensor, thereby reducing the situation where the pressure sensor is damaged.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By setting the bracket, pressure sensor, trigger rod, trigger block and material blocking barrel, the situation of large pieces of material entering the feeding port of the belt conveyor is reduced, so that the large pieces of material and the belt are not easily moved relative to each other, and the belt is less worn by the large pieces of material;

[0025] 2. By setting a lower guide rod, an upper guide rod and a limit plate, the lower guide rod is located below the upper guide rod, so that the trigger rod moves along the length direction of the bracket, so that the trigger rod drives the trigger block to move horizontally to abut against the pressure sensor;

[0026] 3. By providing a rubber layer, the pressure sensor can be less likely to be damaged. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The present application embodiment discloses a sintering production belt anti-blocking device. Figures 1 to 4 , including a group of brackets 1, one of which is equipped with a pressure sensor 2. After the pressure sensor 2 is subjected to force, it is fed back to the control system, and the control system controls the belt conveyor to stop. The brackets 1 are symmetrically installed on both sides of the belt 8, and the length direction of the brackets 1 is placed along the moving direction of the belt 8. A trigger rod 3 is installed on the bracket 1, and the trigger rod 3 slides along the length direction of the bracket 1. A trigger block 4 is installed on the back of the trigger rod 3, and the trigger block 4 is used to abut against the pressure sensor 2 on the side facing the pressure sensor 2. A material blocking barrel 5 is installed between the trigger rods 3, and the side of the material blocking barrel 5 away from the pressure sensor 2 is used to abut against the bulk material 9. In the process of the belt 8 driving the material 9 to move, when the bulk material 9 in the material 9 touches the side of the material blocking barrel 5 away from the pressure sensor 2, because the distance between the bottom of the material blocking barrel 5 and the belt 8 is smaller than the size of the bulk material 9, the material blocking barrel 5 is pushed by the bulk material 9, so that the material blocking barrel 5 drives the trigger rod 3 to move horizontally along the length direction of the bracket 1. When the trigger rod 3 drives the trigger block 4 to move horizontally to contact the pressure sensor 2, the belt 8 stops running, reducing the large pieces of material 9 from entering the unloading port of the belt conveyor. Although the large pieces of material 9 will be intercepted by the blocking barrel 5, the blocking barrel 5 will move with the large pieces of material 9, making it difficult for the large pieces of material 9 and the belt 8 to move relative to each other, reducing the wear of the belt 8 by the large pieces of material 9.

[0034] In order to facilitate the interception of large pieces of material 9, refer to Figures 1 to 4, the material blocking barrel 5 is coaxially arranged with the trigger rod 3, and the end wall of the material blocking barrel 5 is rotatably connected with the opposite surface of the trigger rod 3. The outer wall of the material blocking barrel 5 is provided with an arc surface 51, and the end diameter of the material blocking barrel 5 is larger than the end diameter of the trigger rod 3. When small pieces of material 9 pass between the belt 8 and the material blocking barrel 5, the material blocking barrel 5 rotates to reduce the mutual friction between the material blocking barrel 5 and the material 9. At the same time, the material blocking barrel 5 is coaxially arranged with the trigger rod 3, so that during the rotation of the material blocking barrel 5, the distance between the bottom of the material blocking barrel 5 and the bottom of the belt 8 is always maintained unchanged. And the arc surface 51 is set according to the curvature of the belt 8, so as to reduce the situation where the two sides of the belt 8 are too close to the material blocking barrel 5, so as to facilitate the passage of small pieces of material 9 between the belt 8 and the material blocking barrel 5.

[0035] In order to move the trigger rod 3 along the length direction of the bracket 1, refer to Figures 1 to 4 , a lower guide rod 12 and an upper guide rod 11 are installed on the bracket 1 along the length direction, the lower guide rod 12 and the upper guide rod 11 are parallel to each other, and the lower guide rod 12 is located below the upper guide rod 11. The trigger rod 3 is cylindrical, and the trigger rod 3 is rolled and arranged between the upper guide rod 11 and the lower guide rod 12. The top wall of the trigger rod 3 abuts against the bottom wall of the upper guide rod 11, and the bottom wall of the trigger rod 3 abuts against the top wall of the lower guide rod 12. A limit plate 6 is sleeved on the trigger rod 3, and the limit plate 6 is welded to the trigger rod 3. The back side of the limit plate 6 abuts against the opposite surface of the lower guide rod 12, and the back side of the limit plate 6 abuts against the opposite surface of the upper guide rod 11. The trigger rod 3 is limited by the lower guide rod 12 and the upper guide rod 11 in the height direction, and the trigger rod 3 is limited by the lower guide rod 12 and the upper guide rod 11 in the width direction through the limit plate 6, so that the trigger rod 3 can only move along the length direction of the bracket 1. When the trigger rod 3 moves along the length direction of the bracket 1, the trigger rod 3 rotates, causing the trigger rod 3 to roll between the lower guide rod 12 and the upper guide rod 11, thereby causing rolling friction between the lower guide rod 12 and the upper guide rod 11 and the trigger rod 3, thereby reducing the mutual wear between the lower guide rod 12 and the trigger rod 3, and reducing the mutual wear between the upper guide rod 11 and the trigger rod 3.

[0036] In order to facilitate the contact between the trigger block 4 and the pressure sensor 2, refer to Figures 1 to 4 The trigger block 4 is cylindrical, and the end diameter of the trigger block 4 is larger than the end diameter of the trigger rod 3. The trigger block 4 is coaxially arranged with the trigger rod 3, and the opposite surface of the trigger block 4 is rotatably connected with the opposite surface of the trigger rod 3. During the rotation of the trigger rod 3, the distance between the outer wall of the trigger block 4 and the axis of the trigger rod 3 is always consistent, and the outer wall of the trigger block 4 protrudes from the outer wall of the trigger rod 3, so that the trigger block 4 is easy to abut against the pressure sensor 2.

[0037] In order to prevent the pressure sensor 2 from being damaged, refer to Figures 1 to 4, the pressure sensor 2 is installed on one side of the upper guide rod 11 away from the other upper guide rod 11, and then the upper guide rod 11 blocks the pressure sensor 2 and the material 9 on the belt 8, reducing the situation where the material 9 splashes and collides with the pressure sensor 2. The side wall of the trigger block 4 is wrapped with a rubber layer 7, and the rubber layer 7 is used to contact the pressure sensor 2. When the trigger block 4 contacts the pressure sensor 2, the rubber layer 7 buffers the instantaneous force between the trigger block 4 and the pressure sensor 2, reducing the situation where the pressure sensor 2 is damaged.

[0038] The implementation principle of a sintering production belt anti-large block device in the embodiment of the present application is as follows: during the process of the belt 8 driving the material 9 to move, when the large block material 9 in the material 9 touches the side of the blocking barrel 5 away from the pressure sensor 2, since the distance between the bottom of the blocking barrel 5 and the belt 8 is smaller than the size of the large block material 9, the blocking barrel 5 is pushed by the large block material 9, so that the blocking barrel 5 drives the trigger rod 3 to move horizontally along the length direction of the bracket 1. When the trigger rod 3 drives the trigger block 4 to move horizontally to abut against the pressure sensor 2, the belt 8 stops running, reducing the situation where the large block material 9 enters the unloading port of the belt conveyor. Although the large block material 9 will be intercepted by the blocking barrel 5, the blocking barrel 5 will move with the large block material 9, so that the large block material 9 and the belt 8 are not prone to relative movement, reducing the situation where the belt 8 is worn by the large block material 9.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
