Description

Technical Field

[0001] This invention relates to the field of material blockage clearing technology, specifically, to a device for clearing material blockage during material feeding in a granulation equipment. Background Technology

[0002] Currently, in the production process of high-temperature granulation equipment, the smoothness of the feeding process plays a crucial role in the stability of the entire production process and the quality of the product. Its working principle is to turn powdered materials into granular products through specific molds or processes in a high-temperature environment. However, in actual production, material blockage occurs frequently during feeding, becoming one of the key factors restricting the improvement of production efficiency and product quality.

[0003] A search revealed a patent with publication number CN209522103U that discloses a device for clearing blockages during material feeding in high-temperature granulation equipment. This patent requires an operator to repeatedly impact the blockage block with a steel rod, and rotational operation is also possible. However, manual clearing cannot effectively combine reciprocating and rotational motions, and both methods have drawbacks when used separately. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a device for unblocking material during the feeding of granulation equipment, which improves the unblocking effect by combining linear and rotary motion of the unblocking rod.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is: a device for clearing blockages during material feeding in a granulation equipment, comprising: A feeding pipe having a feeding channel and a discharge port connected to the feeding channel; A clearing rod is vertically movable on the feed pipe and cooperates with the discharge port. The clearing rod is adapted to be moved within the feed pipe to clear the discharge port. A linear drive assembly is provided on the feed pipe, and the linear drive assembly is connected to the unblocking rod to drive the unblocking rod to move in the vertical direction within the feed pipe; A first rotary drive assembly is disposed on the discharge pipe, and the first rotary drive assembly is connected to the unblocking rod to drive the unblocking rod to rotate within the discharge pipe, wherein: A vertical sliding guide mechanism is provided between the first rotary drive assembly and the unblocking rod. The vertical sliding guide mechanism enables the linear drive assembly to simultaneously drive the unblocking rod to make a vertical linear motion when the first rotary drive assembly drives the unblocking rod to rotate.

[0006] Furthermore, in order to separate agglomerated materials, the feeding pipe is provided with a separating mesh plate for separating agglomerated materials in the feeding channel. The separating mesh plate is coaxially arranged with the feeding pipe and is inclined from top to bottom toward the center of the feeding pipe so that the separated agglomerated materials can be moved along the surface of the separating mesh plate toward the center of the feeding pipe. A support base is provided inside the feeding pipe, and a receiving chamber is opened on the support base. The receiving chamber is located near the center of the feeding pipe and is suitable for accommodating materials moving toward the center of the feeding pipe.

[0007] Furthermore, to increase the throughput of unagglomerated material, the unblocking device for material discharge in the granulation equipment also includes a pushing component, which comprises: A rotating sleeve is rotatably mounted on the feed pipe, and the rotating sleeve is coaxially arranged with the unblocking rod. Multiple movable rollers are arranged circumferentially along the rotating sleeve. The movable rollers are parallel to the upper surface of the dividing screen plate. The movable rollers are connected to the rotating sleeve. The rotating sleeve is adapted to drive the movable rollers to move when it is rotated. A second rotary drive assembly is disposed on the feed tube, and the second rotary drive assembly is connected to the rotating sleeve to drive the rotating sleeve to rotate. The separating screen includes a screen wall portion and a mesh portion for allowing material to pass through the screen. The outer wall of the moving roller abuts against the screen wall portion. The moving roller is adapted to be driven to move by the second rotation drive assembly, thereby pushing the material located at the screen wall portion to move and allowing the material to pass through the mesh portion.

[0008] Furthermore, a vibration mechanism is provided on the moving roller, the vibration mechanism comprising: A rotating contact element within the movable roller is used to intermittently strike the separating mesh plate. An elastic element is connected to the mesh plate contact and the moving roller respectively to drive the mesh plate contact to reset; When the moving roller is moved, the mesh plate contact member is alternately located at the mesh opening and the mesh wall. When the mesh plate contact member moves to contact the mesh wall, it is pushed by the mesh wall and rotates. When the mesh plate contact member moves to the mesh opening, it is reset by the elastic element and strikes the separating mesh plate.

[0009] Furthermore, a discharge assembly is provided on the moving roller, the discharge assembly comprising: A conveying channel is formed along the axial direction of the moving roller inside the moving roller to convey agglomerated material from the separating mesh plate to the receiving chamber; A feed channel is provided through the circumferential wall of the moving roller, the feed channel is connected to the conveying channel, and the feed channel is adapted to guide the agglomerated material located on the separator screen into the feed channel when the moving roller is moved to push the material. A discharge port is provided on the side of the moving roller axis near the receiving chamber, the discharge port is connected to the conveying channel, and the discharge port is adapted to discharge the agglomerated material in the conveying channel into the receiving chamber; A first discharge port is provided through the circumferential wall of the moving roller. The first discharge port connects the conveying channel and the external space of the moving roller. The first discharge port is located on one side of the portion of the moving roller that abuts against the partition screen. A first barrier screen is provided inside the first discharge port. The first discharge port is adapted to discharge unagglomerated material that has entered the conveying channel through the first barrier screen.

[0010] Furthermore, in order to pre-treat agglomerated materials, the unblocking device for material discharge in the granulation equipment also includes a dispersing component, which includes: A material contact element is rotatably disposed in the movable roller for intermittently impacting the material entering the conveying channel after being actuated; the material contact element is coaxially disposed with the movable roller. A swing mechanism is connected to the material contact member to drive the material contact member to swing back and forth in the conveying channel, thereby intermittently impacting the material entering the conveying channel.

[0011] Furthermore, a second discharge port is provided inside the support base. The second discharge port is adapted to connect the storage chamber and the external space of the support base. A second barrier net is provided at the connection between the second discharge port and the storage chamber. The second barrier net is adapted to block the lumpy material entering the storage chamber. The second barrier net is also adapted to allow the unlumpy material entering the storage chamber to pass through and be discharged from the second discharge port to the outside of the support base.

[0012] Furthermore, an air jet assembly is provided above the storage chamber, the air jet assembly including at least one nozzle for ejecting gas, the nozzle being adapted to apply the ejected gas to the agglomerated material in the storage chamber.

[0013] Furthermore, the support base is provided with an opening and closing assembly, the opening and closing assembly comprising: A sealing plate is vertically slidably disposed within the support base. The sealing plate is adapted to be moved vertically downwards to close the storage chamber. The nozzle is disposed on the sealing plate. Rotate the elastic component mounted on the support base. The elastic component is connected to the sealing plate to support the sealing plate in the initial position, thereby opening the storage chamber. The unblocking rod is equipped with a pushing member, which is adapted to move downward after being activated, thereby pushing the sealing plate to abut against the storage chamber, so that the storage chamber is sealed. When the storage chamber is sealed, the nozzle discharges gas to process the agglomerated material in the sealed storage chamber.

[0014] Furthermore, the pusher and the sealing plate are provided with a docking mechanism for mutual cooperation. The docking mechanism is adapted to allow the pusher to partially insert into the sealing plate when the pusher and the sealing plate abut against each other. When the pusher is partially inserted into the sealing plate, the first rotary drive assembly is also adapted to synchronously drive the sealing plate and the unblocking rod to rotate.

[0015] By adopting the above technical solution, the present invention has the following beneficial effects: 1. The material is fed into the feeding channel of the feeding pipe through the inlet at the top of the feeding pipe, and finally discharged to the designated position through the outlet of the feeding pipe. During the process of the material passing through the feeding pipe, in order to avoid the material blockage in the outlet of the feeding pipe, the linear drive component can be activated to drive the unblocking rod to move linearly in the feeding pipe. In the working mode of being driven to reciprocate, the unblocking rod can continuously disturb the material and prevent bridging. In the working mode of being driven from the upper position to the lower position, the unblocking rod can exert a strong impact on the blockage point, thereby pushing out the blockage in the feeding pipe. At the same time, due to the setting of the vertical sliding guide mechanism, in both working modes, the unblocking rod can be driven to rotate by activating the first rotary drive component, which further enhances the unblocking effect of the unblocking rod.

[0016] 2. During the process of moving the roller to push the material, the agglomerated material that cannot pass through the separator plate comes into contact with the guide and enters the conveying channel through the feeding channel. In the conveying channel, the agglomerated material can slide down quickly along the inner wall of the conveying channel and be discharged through the discharge port to the receiving chamber. The agglomerated material is separated and collected in the receiving chamber to avoid the agglomerated material directly entering the discharge port of the feed pipe and causing or aggravating the blockage.

[0017] 3. When the unblocking rod is in the lower position, the sealing plate moves to abut against the wall of the receiving chamber, changing the receiving chamber from an open state to a closed state. This isolates the clump material currently in the receiving chamber from the internal space of the discharge pipe, limiting the clump material in the receiving chamber. In this state, the nozzle on the sealing plate sprays air onto the limited clump material, causing it to break up and pass through the second barrier net. When the receiving chamber is in a closed state, the gas sprayed from the nozzle can act more effectively on the clump material, improving the efficiency of processing clump material. At the same time, it will not affect the non-clump material that is normally discharged in the discharge pipe. Compared with traditional jet processing, the gas utilization rate is higher and the effect of breaking up clump material is better. Attached Figure Description

[0019] To make the content of this invention easier to understand, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0020] Example 1: As Figure 1-2 As shown, a device for clearing blockages during material feeding in a granulation equipment includes: Feeding pipe 1, which has a feeding channel and a discharge port connected to the feeding channel; A vertically movable unblocking rod 2 is installed on the feed pipe 1 and is configured to cooperate with the discharge port. The unblocking rod 2 is adapted to be moved within the feed pipe 1 to unblock the discharge port. A linear drive assembly 3 is installed on the feed pipe 1. The linear drive assembly 3 is connected to the unblocking rod 2 to drive the unblocking rod 2 to move in the vertical direction within the feed pipe 1. A first rotary drive assembly 4 is installed on the discharge pipe 1. The first rotary drive assembly 4 is connected to the unblocking rod 2 to drive the unblocking rod 2 to rotate inside the discharge pipe 1, wherein: A vertical sliding guide mechanism is provided between the first rotary drive assembly 4 and the unblocking rod 2. The vertical sliding guide mechanism enables the linear drive assembly 3 to simultaneously drive the unblocking rod 2 to make vertical linear motion when the first rotary drive assembly 4 drives the unblocking rod 2 to rotate.

[0021] Specifically, the unblocking rod 2 has an upper position, a middle position, and a lower position during its movement; The linear drive assembly 3 is adapted to drive the unblocking rod 2 to reciprocate between the upper and middle positions to unblock the discharge port of the feed pipe 1; The linear drive assembly 3 is also adapted to move the unblocking rod 2 from the upper position to the lower position to push the blocked material out of the discharge port and out of the discharge pipe 1, thereby unblocking the discharge pipe 1.

[0022] The unblocking device for material blockage during the feeding of granulation equipment may also include a controller, which is a PLC and is used to control the operation of each component.

[0023] In this embodiment, the material is fed into the feeding channel of the feeding pipe 1 through the inlet above the feeding pipe 1, and finally discharged to the designated position through the outlet of the feeding pipe 1. During the process of the material passing through the feeding pipe 1, in order to avoid the material blockage in the outlet of the feeding pipe 1, the linear drive component 3 can be activated to drive the unblocking rod 2 to move linearly in the feeding pipe 1. In the working mode of being driven to reciprocate, the unblocking rod 2 can continuously disturb the material and prevent bridging. In the working mode of being driven from the upper position to the lower position, the unblocking rod 2 can exert a strong impact on the blockage point in the outlet, thereby pushing the material causing the blockage in the outlet out of the outlet. At the same time, due to the setting of the vertical sliding guide mechanism, the unblocking rod 2 can be driven to rotate by activating the first rotary drive component 4 in both working modes, which further enhances the unblocking effect of the unblocking rod 2.

[0024] like Figure 3 As shown, the linear drive assembly 3 includes a piston cylinder 31, which is mounted on the feed pipe 1. A connecting plate 32 is connected to the telescopic end face of the piston cylinder 31. The unblocking rod 2 is rotatably connected to the connecting plate 32. The piston cylinder 31 is adapted to drive the connecting plate 32 to move in the vertical direction within the feed pipe 1, thereby driving the unblocking rod 2 to move.

[0025] Specifically, the linear drive component 3 can also be a cylinder or an electric cylinder, which can be selected according to actual needs. This part is existing technology, and its specific structure and working principle will not be described in detail here.

[0026] like Figure 3-4As shown, the first rotary drive assembly 4 includes a first motor 41, a first drive gear 42, and a first driven gear 43 meshing with the first drive gear 42. The first motor 41 is mounted on the feed pipe 1, the first drive gear 42 is mounted on the output shaft of the first motor 41, a gear seat 44 is fixedly connected to the feed pipe 1, and the first driven gear 43 is rotatably mounted on the gear seat 44 and is coaxially arranged with the unblocking rod 2. The vertical sliding guide mechanism includes multiple grooves 33 formed on the outer wall of the unblocking rod 2 and multiple sliders 34 arranged on the inner ring of the first driven gear 43 that cooperate with the grooves 33. The sliders 34 are slidably arranged in the grooves 33 in the axial direction of the unblocking rod 2.

[0027] In this embodiment, when it is necessary to rotate the unblocking rod 2 to improve the unblocking effect, the first motor 41 is started to drive the first driving gear 42 to rotate, which in turn drives the first driven gear 43 to rotate, thereby driving the unblocking rod 2 to rotate. While the unblocking rod 2 is rotating, the linear drive component 3 can synchronously drive the unblocking rod 2 to move in the vertical direction through the cooperation of the slider 34 and the slide groove 33. The combination of rotation and linear motion makes the unblocking effect of the unblocking rod 2 better. With the cooperation of the slider 34 and the slide groove 33, no matter how much the linear drive component 3 drives the unblocking rod 2 to move vertically, it can ensure that the first driven gear 43 always remains connected to the unblocking rod 2.

[0028] Example 2: Figure 5-6 As shown, this embodiment further includes the following structure based on embodiment one: the feeding pipe 1 is provided with a separating mesh plate 5 for separating agglomerated materials in the feeding channel. The separating mesh plate 5 is coaxially arranged with the feeding pipe 1. The separating mesh plate 5 is inclined from top to bottom to the center of the feeding pipe 1 so that the separated agglomerated materials can be moved along the surface of the separating mesh plate 5 to the center of the feeding pipe 1. A support base 6 is provided inside the feed pipe 1. A receiving chamber 61 is provided on the support base 6. The receiving chamber 61 is located near the center of the feed pipe 1 and is suitable for accommodating the material moving towards the center of the feed pipe 1.

[0029] Specifically, one end of the partition screen 5 is connected to the feed pipe 1, and the other end is connected to the support base 6, which can support the partition screen 5.

[0030] In this embodiment, in order to avoid a large amount of agglomerated material entering the outlet of the feed pipe 1 and causing blockage, a separator screen 5 is provided to screen the material entering the feed pipe 1. Material with a size smaller than the mesh size of the separator screen 5 is unagglomerated material and can pass directly through the separator screen 5, while material with a size larger than the mesh size of the separator screen 5 is agglomerated material and will be blocked, so that it cannot pass directly through the separator screen 5 and enter the outlet of the feed pipe 1. To prevent a large amount of clumped material from remaining on the separator plate 5, which would block the passage of non-clumped material, the separator plate 5 is tilted downwards. The blocked clumped material can move along the downward tilted surface of the separator plate 5 into the receiving chamber 61, avoiding prolonged stay at the separator plate 5 and reducing the impact on non-clumped material.

[0031] like Figure 5 , Figure 7 As shown, the unblocking device for material blockage during the granulation equipment feeding process may further include a pushing component 7, which includes: Rotary sleeve 71 is mounted on feed pipe 1 and is coaxially mounted with unblocking rod 2. Multiple movable rollers 72 are arranged circumferentially along the rotating sleeve 71. The movable rollers 72 are parallel to the upper surface of the dividing screen plate 5. The movable rollers 72 are connected to the rotating sleeve 71. The rotating sleeve 71 is adapted to drive the movable rollers 72 to move when it is rotated. A second rotary drive assembly 73 is provided on the feed pipe 1. The second rotary drive assembly 73 is connected to the rotating sleeve 71 to drive the rotating sleeve 71 to rotate. The separator plate 5 includes a mesh wall portion and a mesh opening portion for allowing material to pass through the separator plate 5. The outer wall of the moving roller 72 abuts against the mesh wall portion. The moving roller 72 is adapted to be driven to move by the second rotation drive assembly 73, thereby pushing the material located at the mesh wall portion to move and allowing the material to pass through the mesh opening portion.

[0032] In this embodiment, since some unagglomerated material is located at the mesh wall after falling onto the separating mesh plate 5, it cannot pass directly through the separating mesh plate 5 even if it is not agglomerated. Therefore, the second rotary drive assembly 73 can be activated to drive multiple moving rollers 72 to move. During the movement, the moving rollers 72 push the material located at the mesh wall to move, so that the unagglomerated material can pass through the mesh opening better.

[0033] like Figure 3 , Figure 5 As shown, the second rotary drive assembly 73 includes a second motor 731, a second drive gear 732, and an internal gear ring 733 meshing with the second drive gear 732. The second motor 731 is mounted on the feed tube 1, the second drive gear 732 is connected to the output shaft of the second motor 731, and the internal gear ring 733 is connected to the inner wall of the rotating sleeve 71.

[0034] In this embodiment, when it is necessary to drive the moving roller 72 to move in order to complete the material pushing work, the second motor 731 is started to drive the second drive gear 732 to rotate, which in turn drives the internal gear ring 733 to rotate, thereby realizing the rotation of the rotating sleeve 71. During the rotation of the rotating sleeve 71, the moving roller 72 can be driven to rotate.

[0035] like Figure 7-8As shown, a vibration mechanism can be provided on the moving roller 72, and the vibration mechanism includes: The screen contact element 8, which is rotatably set inside the moving roller 72, is used to intermittently strike the separating screen plate 5; Elastic element 81 is connected to screen contact 8 and moving roller 72 respectively to drive screen contact 8 to reset; When the moving roller 72 is moved, the mesh plate contact member 8 is alternately located at the mesh opening and the mesh wall. When the mesh plate contact member 8 moves to contact the mesh wall, it is pushed by the mesh wall and rotates. When the mesh plate contact member 8 moves to the mesh opening, it is reset by the elastic element 81 and strikes the separating mesh plate 5.

[0036] Specifically, a rotating rod is connected to the screen contact component 8, and the rotating rod is rotatably mounted on the moving roller 72; The elastic element 81 is a return spring, which is sleeved on the outside of the rotating rod. The two ends of the return spring are connected to the mesh plate contact element 8 and the moving roller 72, respectively.

[0037] In this embodiment, to further improve the efficiency of unagglomerated material passing through the separating screen plate 5, a vibration mechanism is provided. During the movement of the moving roller 72, the screen plate contact member 8 alternately positions itself at the mesh opening and the mesh wall of the separating screen plate 5. When the screen plate contact member 8 is located at the mesh opening, the return spring is in its natural state. When the screen plate contact member 8 contacts the mesh wall, it is pushed by the mesh wall, resulting in a certain rotation. At this time, the return spring is twisted. When the screen plate contact member 8 moves back to the mesh opening, it loses the thrust from the mesh wall and can be reset by the return spring. At the moment the screen plate contact member 8 resets, it impacts the separating screen plate 5, resulting in a slight vibration effect, thereby accelerating the speed of unagglomerated material passing through the separating screen plate 5.

[0038] like Figure 7 , Figure 9 As shown, a discharge assembly may also be provided on the moving roller 72, the discharge assembly including: A conveying channel 721 is formed along the axial direction of the moving roller 72 inside the moving roller 72 for conveying agglomerated material from the separating mesh plate 5 to the receiving chamber 61; A feed channel 722 is provided through the circumferential wall of the moving roller 72. The feed channel 722 is connected to the conveying channel 721. The feed channel 722 is adapted to guide the agglomerated material located on the separator screen 5 into the feed channel 722 when the moving roller 72 is moved to push the material. A discharge port 723 is provided on the side of the moving roller 72 that is axially close to the receiving chamber 61. The discharge port 723 communicates with the conveying channel 721 and is adapted to discharge the agglomerated material in the conveying channel 721 into the receiving chamber 61. A first discharge port 724 is provided through the circumferential wall of the moving roller 72. The first discharge port 724 connects the conveying channel 721 and the external space of the moving roller 72. The first discharge port 724 is located on one side of the part of the moving roller 72 that abuts against the partition screen 5. A first barrier screen 725 is provided inside the first discharge port 724. The first discharge port 724 is suitable for discharging unagglomerated material that has entered the conveying channel 721 through the first barrier screen 725.

[0039] In this embodiment, the opening direction of the feed channel 722 is consistent with the movement direction of the moving roller 72.

[0040] Specifically, a guide portion 726 is provided on the moving roller 72. The guide portion 726 is arranged adjacent to the feeding channel 722. When the moving roller 72 is moved and comes into contact with the material, the material is guided along the outer contour arc surface of the guide portion 726 to the feeding channel 722, so that the guided material finally enters the conveying channel 721.

[0041] In this embodiment, to prevent the agglomerated material blocked by the separator 5 from failing to move quickly along the surface of the separator 5 into the receiving chamber 61 due to high friction, thus obstructing the unagglomerated material, a discharge assembly is provided. During the movement of the moving roller 72 to push the material, the agglomerated material that cannot pass through the separator 5 contacts the guide portion 726 and enters the conveying channel 721 through the feeding channel 722. Within the conveying channel 721, the agglomerated material can quickly slide down the inner wall of the conveying channel 721 and pass through... The material is discharged through the discharge port 723 to the receiving chamber 61, reducing the time that the agglomerated material stays on the separator plate 5. While the guide part 726 guides the agglomerated material into the conveying channel 721, some unagglomerated material will also enter the conveying channel 721. This part of the unagglomerated material can return to the separator plate 5 after passing through the first barrier net 725 in the first discharge port 724, and finally pass through the separator plate 5. The first barrier net 725 can also prevent the agglomerated material in the conveying channel 721 from returning to the separator plate 5 through the first discharge port 724.

[0042] like Figure 10-11 As shown, the unblocking device for material blockage during granulation equipment feeding may also include a dispersing component, which includes: A material contact element 9 is rotatably installed in the movable roller 72 for intermittently impacting the material entering the conveying channel 721 after being activated. The material contact element 9 is coaxially arranged with the movable roller 72. The oscillating mechanism 91 is connected to the material contact member 9 to drive the material contact member 9 to oscillate back and forth in the conveying channel 721, thereby intermittently impacting the material entering the conveying channel 721.

[0043] Specifically, the material contact member 9 includes an impact part 727 and a closing part 728. The impact part 727 is adapted to impact the material when the material contact member 9 is activated and comes into contact with the material, thereby breaking up the material. The closing part 728 is adapted to block the feed channel 722 when the impact part 727 impacts the material. After the material contact element 9 is activated, it moves from near the feed channel 722 to the first discharge port 724, thereby pushing the material entering the conveying channel 721 from the feed channel 722 to the first discharge port 724 and impacting the material, so that the clumped material is dispersed and the scattered unclumped material can be better discharged through the first discharge port 724 and through the separator screen 5.

[0044] In this embodiment, the moving roller 72 is moved. During the movement, the agglomerated material enters the conveying channel 721 through the feeding channel 722 and is finally discharged to the receiving chamber 61 through the discharge port 723. In order to avoid excessive accumulation of agglomerated material in the receiving chamber 61, a dispersing component is provided to disperse the agglomerated material entering the conveying channel 721. This allows some of the agglomerated material to be dispersed in advance during its movement from the conveying channel 721 to the receiving chamber 61 and then leave the conveying channel 721 through the first barrier net 725 and finally pass through the separator plate 5. The specific dispersing method is as follows: the material contact member 9 reciprocates under the drive of the swing mechanism 91. When the material contact member 9 moves from near the feed channel 722 to the first discharge port 724, the impact part 727 pushes and impacts the material. During this process, the sealing part 728 blocks the feed channel 722 to prevent the material contact member 9 from pushing the material located in the feed channel 722 to the opposite direction of the first discharge port 724 during the reverse movement. During the process of closing the feed channel 722, the moving roller 72 continues to move. The agglomerated material that cannot enter due to the closing of the feed channel 722 is temporarily pushed by the moving roller 72. When the feed channel 722 is opened again, this part of the agglomerated material can continue to enter the conveying channel 721 under the continuous push of the moving roller 72.

[0045] like Figure 11 As shown, the swing mechanism 91 can specifically have the following structure, including: A swing block 911 connected to the material contact component 9; A matching spring 912 is connected to the swing block 911 and the moving roller 72 respectively. The matching spring 912 is adapted to drive the swing block 911 to reset. A drive ring 913 is provided on the feed pipe 1 and cooperates with the swing block 911. The drive ring 913 has multiple spaced mating grooves 914 and a force-bearing part 915 is provided between two adjacent mating grooves 914. When the swing block 911 moves to contact the force receiving part 915, the force receiving part 915 pushes the swing block 911 to rotate. When the swing block 911 is moved to the mating groove 914, the swing block 911 is reset to the initial state by the mating spring 912.

[0046] In this embodiment, when the moving roller 72 is moved, the swing block 911 alternately positions at the mating groove 914 and the force-receiving part 915. When the moving roller 72 moves to the position of the swing block 911 at the mating groove 914, the swing block 911 is not under force, and the mating spring 912 is in a natural state. When the moving roller 72 moves to the position of the swing block 911 at the force-receiving part 915 and contacts the force-receiving part 915, the force-receiving part 915 in the stationary state generates a pushing force on the swing block 911, causing the swing block 911 to rotate around the axis of the moving roller 72. During the rotation of the swing block 911, the material contact member 9 is driven to rotate from the direction of the feeding channel 722 to the direction of the first discharge port 724, thereby impacting the material entering the conveying channel 721 towards the direction of the first discharge port 724. During this process, some of the agglomerated material can be processed to avoid excessive agglomerated material accumulating in the receiving chamber 61.

[0047] Furthermore, the positional relationship between the swing block 911 and the material contact component 9, such as... Figure 9 As shown, when the swing block 911 is located at the mating groove 914, the material contact member 9 is in the initial state and located on the side of the feed channel 722 away from the first discharge port 724. When the swing block 911 is pushed and rotated by the force-receiving part 915, the material contact member 9 moves from the initial state position to the first discharge port 724 and passes through the feed channel 722.

[0048] Example 3: Figure 12-13 As shown, this embodiment further includes the following structure based on embodiment one: a second discharge port 10 is provided in the support base 6, the second discharge port 10 is adapted to connect the storage chamber 61 and the external space of the support base 6, a second barrier net 101 is provided at the connection between the second discharge port 10 and the storage chamber 61, the second barrier net 101 is adapted to block the lumped material entering the storage chamber 61, and the second barrier net 101 is also adapted to allow the unlumped material entering the storage chamber 61 to pass through and be discharged from the second discharge port 10 to the outside of the support base 6.

[0049] In this embodiment, the material accumulated in the receiving chamber 61 includes not only lumpy material, but also a small amount of unlumpy material that has slid off the partition mesh 5 or entered the receiving chamber 61 through the conveying channel 721. In order to discharge the unlumpy material out of the receiving chamber 61, a second discharge port 10 is provided. The second barrier mesh 101 provided in the second discharge port 10 blocks the lumpy material in the receiving chamber 61, while the unlumpy material can enter the second discharge port 10 through the second barrier mesh 101 and enter the discharge pipe 1 through the second discharge port 10 to move to the outlet of the discharge pipe 1.

[0050] like Figure 12-13 As shown, an air jet assembly is provided above the receiving chamber 61. The air jet assembly includes at least one nozzle 102 for ejecting gas. The nozzle 102 is adapted to apply the ejected gas to the agglomerated material in the receiving chamber 61.

[0051] Specifically, multiple nozzles 102 can be spaced out to increase the rate of processing agglomerated materials.

[0052] In this embodiment, the nozzle 102 can spray gas to impact the agglomerated material accumulated in the receiving chamber 61, disperse the agglomerated material so that it can pass through the second barrier net 101 and finally enter the discharge pipe 1 through the second discharge port 10.

[0053] like Figure 12-13 As shown, the support base 6 is equipped with an opening and closing assembly, which includes: A sealing plate 103 is vertically slidably disposed in the support base 6. The sealing plate 103 is adapted to be moved vertically downward to close the storage chamber 61. A nozzle 102 is disposed on the sealing plate 103. Rotate the elastic component 104 mounted on the support base 6. The elastic component 104 is connected to the sealing plate 103 to support the sealing plate 103 in the initial position, thereby opening the storage chamber 61. The unblocking rod 2 is provided with a pusher 105, which is adapted to move downward after being activated, thereby pushing the sealing plate 103 to abut against the storage chamber 61, so that the storage chamber 61 is sealed. When the storage chamber 61 is closed, the nozzle 102 discharges gas to process the clumped material in the closed storage chamber 61.

[0054] In this embodiment, when the linear drive assembly 3 moves the unblocking rod 2 to the upper and middle positions, the pusher 105 does not exert pressure on the sealing plate 103. When the linear drive assembly 3 moves the unblocking rod 2 to the lower position, the pusher 105 exerts pressure on the sealing plate 103 while following the movement of the unblocking rod 2, and simultaneously squeezes the elastic component 104. When the unblocking rod 2 is at the lower position, the sealing plate 103 moves to abut against the wall of the receiving chamber 61, causing the receiving chamber 61 to change from an open state to a closed state, thus discharging the clumps of material currently located in the receiving chamber 61 into the lower position. The internal space of the feed pipe 1 is isolated, which limits the agglomerated material in the receiving chamber 61. In this state, the nozzle 102 on the sealing plate 103 sprays air onto the limited agglomerated material, so that the agglomerated material is broken up and passes through the second barrier net 101. When the receiving chamber 61 is in a closed state, the gas sprayed by the nozzle 102 can act better on the agglomerated material, improving the efficiency of processing agglomerated material, while not affecting the non-agglomerated material that is normally fed into the feed pipe 1. Compared with the traditional jet processing, the gas utilization rate is higher and the effect of breaking up agglomerated material is better.

[0055] like Figure 12 As shown, the elastic component 104 includes a rotating seat 106 rotatably mounted on the support seat 6, a plurality of telescopic rods 108 connected to the rotating seat 106, and telescopic springs 107 sleeved on the telescopic rods 108. One end of the telescopic rod 108 is connected to the rotating seat 106, and the other end of the telescopic rod 108 is connected to the sealing plate 103. The two ends of the telescopic spring 107 are connected to the rotating seat 106 and the sealing plate 103 respectively.

[0056] In this embodiment, during the process of the pusher 105 squeezing the sealing plate 103 to close the storage chamber 61, the sealing plate 103 moves downward and squeezes the telescopic rod 108 and the telescopic spring 107. When the linear drive assembly 3 drives the unblocking rod 2 to move upward, the sealing plate 103, which has lost pressure, resets under the action of the telescopic spring 107 and opens the storage chamber 61.

[0057] like Figure 12 As shown, the pusher 105 and the sealing plate 103 are provided with a docking mechanism for mutual cooperation. The docking mechanism is adapted to allow the pusher 105 to partially insert into the sealing plate 103 when the pusher 105 and the sealing plate 103 abut against each other. When the pusher 105 is partially inserted into the sealing plate 103, the first rotary drive assembly 4 is also adapted to synchronously drive the sealing plate 103 and the unblocking rod 2 to rotate.

[0058] Specifically, the docking mechanism includes a docking groove 109 formed on the sealing plate 103 and a docking block 110 set on the pusher 105.

[0059] In this embodiment, the pusher 105 is moved toward the sealing plate 103 and comes into contact with the sealing plate 103. During the contact process, the docking block 110 is inserted into the docking groove 109. At this time, the first rotary drive assembly 4 is activated, which can simultaneously drive the unblocking rod 2 and the sealing plate 103 to rotate. When the sealing plate 103 is pushed into the closed storage chamber 61, the sealing plate 103 is driven to rotate by the first rotary drive assembly 4, which can drive the nozzles 102 on the sealing plate 103 to rotate synchronously with the axis of the feed pipe 1 as the center. The clumped material in the entire storage chamber 61 is processed in a rotating manner, thereby improving the processing speed and reducing the number of nozzles 102 required.

[0060] like Figure 12 As shown, the jet assembly also includes an air supply device and an air intake channel. The air intake channel includes a direct current channel 111 disposed on the unblocking rod 2, a first flow channel 112 disposed on the pusher 105, and a second flow channel 113 disposed on the sealing plate 103. The air supply device is adapted to supply gas into the direct current channel 111. The DC channel 111 is connected to the first flow channel 112. The first flow channel 112 is adapted to be connected to the second flow channel 113 when the docking block 110 is engaged with the docking groove 109. The second flow channel 113 is connected to the nozzle 102.

[0061] Specifically, a connecting hose is provided between the gas supply device and the unblocking rod 2. One end of the connecting hose is connected to the gas outlet of the gas supply device, and the other end of the connecting hose is connected to the top end face of the unblocking rod 2 through a rotating seal, thereby introducing the gas supplied by the gas supply device into the direct current channel 111.

[0062] The gas supply device may also include a compression component for compressing the gas and a component for monitoring the gas flow rate. The gas supply device and connecting hose are not shown in the figure. This part is prior art, and its specific structure and working principle will not be described in detail here.

[0063] In this embodiment, when the pusher plate is pushed and moved, causing the receiving chamber 61 to be closed, the docking block 110 is inserted into the docking groove 109 to form a seal. A sealing gasket or other sealing element can be set between the two. In this case, the controller starts the gas supply device. After the gas supply device introduces gas into the DC channel 111, the gas enters the second flow channel 113 along the first flow channel 112 and finally enters the nozzle 102. After being discharged from the nozzle 102, it acts on the agglomerated material.

[0064] like Figure 12 As shown, the push plate is provided with an upwardly inclined part 114 for guiding the material to slide into the storage chamber 61, and the storage chamber 61 is provided with a downwardly inclined part 115 for guiding the material to slide towards the center of the storage chamber 61.

[0065] In this embodiment, the nozzle 102 processes the agglomerated material located below it in the working state. After being blown away, the agglomerated material moves irregularly in the closed receiving chamber 61. Driven by the first rotary drive assembly 4, the sealing plate 103 rotates with the lower feed tube 1 axis as the center. When the nozzle 102 leaves the previously blown area, the material at the previously blown area gathers towards the center of the receiving chamber 61 along the upper inclined portion 114 and / or the lower inclined portion 115, so as to ensure that when the nozzle 102 rotates above that area again, the agglomerated material at that area can be better dispersed. The specific principle of the material gathering towards the center of the receiving chamber 61 along the upper inclined portion 114 and / or the lower inclined portion 115 is as follows: when the agglomerated material is dispersed and moves irregularly in the closed receiving chamber 61, the nozzle 102 is in a continuous state of motion. After the material that was previously blown and moved irregularly loses the blowing force of the gas ejected from the nozzle 102, part of the material comes into contact with the lower inclined portion 115 and gathers to the center of the receiving chamber 61, that is, above the second barrier net 101, under the guidance of the lower inclined portion 115. Another part of the material comes into contact with the upper inclined portion 114. When the wind power is lost, part of this part of the material falls to the center of the receiving chamber 61 due to gravity, and part slides along the upper inclined portion 114 to the lower inclined portion 115 and is guided to the center of the receiving chamber 61 by the lower inclined portion 115. In this configuration, after each blow of the agglomerated material by the nozzle 102, the agglomerated material that has not been completely dispersed will gather at the center of the collection chamber 61, that is, directly below the nozzle 102, so that when the nozzle 102 is rotated to that position, the agglomerated material can be better processed. Therefore, even if multiple nozzles 102 are provided, they should be arranged at intervals to ensure that the agglomerated material that has not been completely dispersed can gather again at the center of the collection chamber 61 after one blow.

[0066] The working principle of this embodiment is as follows: The controller controls the linear drive component 3 to drive the unblocking rod 2 to move in the feed pipe 1 to complete the unblocking work. The unblocking rod 2 has two working modes under the drive of the linear drive component 3. The two working modes are alternated. When it is in the reciprocating motion working mode, the unblocking rod 2 reciprocates between the upper position and the middle position to unblock the feed pipe 1. In this mode, the pusher 105 on the unblocking rod 2 does not affect the sealing plate 103. After the reciprocating motion working mode has been in operation for a fixed period of time, the controller switches the unblocking rod 2 from the upper position to the lower position, and performs a strong impact on the easily blocked part. After the unblocking rod 2 moves to the lower position, it needs to stay for a period of time. During this period of time, the collection chamber 61 is in a closed state, and the jet component works to process the clumps in the collection chamber 61, so as to avoid the collection chamber 61 being saturated and unable to continue to hold more clumps. After the dwell time ends, the controller continues to control the unblocking rod 2 to reciprocate. At this time, the collection chamber 61 returns to the open state to collect the clumps of material that accumulated outside the collection chamber 61 during the closed state and subsequent clumps of material. While the unblocking rod 2 reciprocates, the receiving chamber 61 receives clumps of material, and the unblocking rod 2 powerfully impacts easily clogged areas. At the same time, the receiving chamber 61 closes and the clumps of material are processed by the jet assembly, forming a complete workflow. The continuous cycle of this workflow further improves the unblocking effect.
