Description

Technical Field

[0001] The present invention relates to the technical field of material conveying anti-blocking, and more specifically, to an anti-blocking device for conveying granular products. Background Art

[0002] In the process of fertilizer production, to meet product specifications and application requirements, the prepared fertilizer is usually processed into granular form by a granulator. In the subsequent conveying process, a vibrating screen plays a screening role to screen out fertilizers that do not meet the product specification requirements. However, the granular fertilizers produced by the granulator do not have a completely uniform shape. In addition to the regular granular shape, some fertilizers are oval or other irregular shapes. Such granules with special shapes are extremely likely to get stuck in the sieve holes of the sieve plate when passing through the sieve plate of the vibrating screen.

[0003] As production continues, the fertilizer granules stuck on the sieve plate accumulate continuously. This will not only greatly reduce the screening efficiency of the sieve plate, seriously affect the screening effect, resulting in unqualified products being mixed into the finished products, but also increase the difficulty of equipment maintenance. To maintain the normal operation of the sieve plate, workers need to regularly clean the sieve plate manually. This process not only consumes a large amount of manpower and time, but also causes intermittent shutdowns of the production line, greatly reducing the overall production efficiency and raising the production cost. Therefore, in the fertilizer production field, a fertilizer conveying and screening anti-blocking device is needed.

[0004] Therefore, to solve the above technical problems, the present application proposes an anti-blocking device for conveying granular products. Summary of the Invention

[0005] The purpose of the present invention is to provide an anti-blocking device for conveying granular products to solve the problems raised in the above background art.

[0006] To achieve the above purpose, in the first aspect, the present invention provides the following technical solution: an anti-blocking device for conveying granular products, including a driving mechanism, a roller, and a guiding mechanism;

[0007] The driving mechanism includes a motor, a lead screw, and a nut block. The driving end of the motor is connected to one end of the lead screw through a coupling, and the lead screw is threadedly connected to the nut block;

[0008] The guiding mechanism includes a slider and a guiding shaft, and the slider is slidably connected to the guiding shaft;

[0009] The guiding shaft is arranged parallel to the lead screw and on the same horizontal plane. One end of the roller is rotatably connected to the nut block, the other end of the roller is rotatably connected to the slider, and a gear is installed on the roller, and a rack is meshed with the gear.

[0010] Preferably, a rotary brush is installed on the drum. The rotary brush is resilient. The drum drives the rotary brush to move and rotate. Due to the resilience of the rotary brush, the extrusion of granular products can be better completed.

[0011] Preferably, the rotary brush is spiral-shaped, and a guide box is arranged at the position corresponding to the rotary brush. One end of the guide box is connected to the nut block, and the other end of the guide box is connected to the slider. Since the rotary brush is spiral-shaped, after the rotary brush brushes off the debris, the debris falling into the guide box will move in one direction under the drive of the rotary brush, which is convenient for collection.

[0012] Preferably, a collection box is arranged at the position corresponding to the guide box, which can collect the debris.

[0013] Preferably, it further includes a support frame. The motor, the guide post and the rack are all installed on the support frame. The lead screw is rotatably connected to the support frame, and the collection box is fixed on the support frame.

[0014] In a second aspect, the present invention provides the following technical solution: a vibrating screen with an anti-blocking device. Applying the anti-blocking device to the vibrating screen can facilitate the sustainable operation of the vibrating screen.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The motor drives the nut block to drive the drum to move through the lead screw. While the drum is moving, through the meshing connection between the gear and the rack, the drum can also rotate. The surface of the drum can extrude the granular products stuck in the sieve holes, preventing them from getting stuck in the sieve holes.

[0016] It can not only improve the screening efficiency, but also reduce the manual cleaning work and improve the production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] During the fertilizer production process, to meet product specifications and application requirements, the prepared fertilizer is usually processed into granular form by a granulator. In the subsequent conveying process, the vibrating screen 9 plays a screening role, screening out fertilizers that do not meet the product specification requirements. However, the granular fertilizers produced by the granulator do not have a completely uniform shape. In addition to the regular granular shape, some fertilizers are oval or other irregular shapes. Such granular fertilizers with special shapes are extremely likely to get stuck in the sieve holes of the sieve plate 91 of the vibrating screen 9 when passing through the sieve plate 91.

[0025] As production continues, the fertilizer particles stuck on the sieve plate 91 accumulate continuously. This will not only greatly reduce the screening efficiency of the sieve plate 91, seriously affect the screening effect, resulting in unqualified products being mixed into the finished products, but also increase the difficulty of equipment maintenance. To maintain the normal operation of the sieve plate 91, the staff needs to regularly clean the sieve plate 91 manually. This process not only consumes a large amount of manpower and time, but also causes intermittent shutdown of the production line, greatly reducing the overall production efficiency and raising the production cost. Therefore, in the fertilizer production field, a fertilizer conveying and screening anti-blocking device is needed.

[0026] Embodiment 1:

[0027] It includes a driving mechanism 13, a roller 4 and a guiding mechanism 14.

[0028] The driving mechanism 13 includes a motor 1, a lead screw 2 and a nut block 3. The driving end of the motor 1 is connected to one end of the lead screw through a coupling, and the lead screw 2 is in threaded connection with the nut block 3; the guiding mechanism 14 includes a slide block 5 and a guide shaft 8. The slide block 5 is slidably connected to the guide shaft 8. The slide block 5 can be an oil-free bushing or a linear bearing, etc., which will not be elaborated here.

[0029] The guide shaft 8 is arranged in parallel with the lead screw 2 and located in the same horizontal plane. Both ends of the roller 4 are rotatably connected to the nut block 3 and the slider 5 respectively, and a gear 6 is coaxially connected to the roller 4. The gear 6 can be arranged at any position on the roller 4. For the convenience of use and maintenance, the gear 6 is usually arranged at the end of the roller 4; a rack 7 is also arranged at the position corresponding to the gear 6, and the rack 7 is connected to the gear 6.

[0030] Please refer to Figure 1 , the motor 1 drives the lead screw 2 to rotate, thereby driving the nut block 3 to move horizontally. The nut block 3 drives the roller 4 to move horizontally. When the roller 4 moves, it will drive the gear 6 to move. The gear 6 moves on the rack 7. Since the rack 7 and the gear 6 are meshed, the gear 6 will drive the roller 4 to rotate.

[0031] The anti-blocking device is arranged at the bottom of the vibrating screen 9, and the position of the roller 4 is set corresponding to the position of the sieve plate 91. The roller 4 is arranged below the sieve plate 91. When the roller 4 moves, it can extrude the particulate matter stuck in the sieve plate 91, thereby preventing the particulate matter from being stuck in the sieve plate 91 and affecting the screening effect. At the same time, it can also reduce the subsequent manual cleaning steps and improve the production efficiency.

[0032] When the motor 1 rotates a certain number of turns in one direction, it means that the nut block 3 has moved to the limit position at this time, which is set in advance according to the size of the lead screw 2 and will not be elaborated here; then the motor 1 will reverse, so that the nut block 3 drives the roller 4 to move back, thereby achieving the purpose of continuous cleaning.

[0033] In addition, please refer to Figure 2 , on the basis of the above, in order to enable the roller 4 to rotate better, gears 6 can be arranged at both ends of the roller 4. Through the cooperation of the gears 6 and the rack 7 on both sides of the roller 4, both ends of the roller 4 are stressed, thereby improving the rotation stability of the roller 4.

[0034] In order to prevent dust or fertilizer debris from affecting the operation of the gear 6, the lead screw 2 and the guide shaft 8, a protective shell is arranged on the surfaces of the gear 6, the lead screw 2 and the guide shaft 8, which is not shown in the figure and will not be elaborated here.

[0035] Since the roller 4 needs to extrude the particulate matter stuck in the sieve holes of the sieve plate 91, the roller 4 needs to closely adhere to the sieve plate 91. In this way, the product accuracy and installation requirements are relatively high, and the roller 4 needs to rub against the particulate matter, which will affect the service life of the roller 4.

[0036] Embodiment 2:

[0037] On the basis of the above Embodiment 1, as Figure 2As shown, a roller brush 41 is provided on the roller 4, and the roller brush 41 has toughness. The roller 4 drives the roller brush 41 to move and rotate, and the product in the sieve holes of the sieve plate 91 is squeezed by the roller brush 41. Different roller brushes 41 are used according to actual conditions. Not only can the position installed on the vibrating screen 9 be flexibly adjusted, even if there is a deviation in the installation position, the roller brush 41 can also squeeze the granular product due to its toughness, and the friction between the roller 4 and the product can also be avoided. The roller brush 41 has toughness, so it can squeeze the product stuck in the sieve hole, and it is easy to replace the roller brush 41 after it is damaged.

[0038] When the granulator forms fertilizer into granular products, there may be residual debris on the surface of the fertilizer granular products, and these debris may be stuck in the sieve holes. Therefore, after the roller brush 41 is cleaned, these debris may be adsorbed on the roller brush 41 or fall to the ground, which not only causes waste of fertilizer raw materials, but also requires subsequent cleaning, which is not conducive to sustainable production.

[0039] Embodiment 3:

[0040] On the basis of the above-mentioned embodiment 1, Figure 2-3 As shown, the texture of the roller brush 41 is spiral-shaped, and a guide box 12 is arranged below the roller brush 41. The two ends of the guide box 12 are respectively arranged on the nut block 3 and the slider 5. The guide box 12 is arranged close to the roller brush 41. In order to facilitate the comparison of the position relationship, a long distance is spaced in the figure. Since the roller brush 41 is spiral-shaped, after the roller brush 41 brushes off the debris, the debris falling into the guide box 12 will move in one direction under the drive of the roller brush 41, and a collection box 10 is arranged at both ends of the guide box 12 for collecting the debris in the guide box 12. The two ends of the guide box 12 can be open or have slots, so that the debris can fall into the collection box 10 below. Regardless of whether the motor 1 rotates forward or reverse, the collection boxes 10 at both ends can collect the debris. In addition, the collection box 10 can also be set to be inclined so that the debris in the collection box 10 flows in one direction under the influence of gravity, which is convenient for collection.

[0041] In the above-mentioned embodiments, various components are directly arranged on the vibrating screen 9, wherein the motor 1 is installed on the vibrating screen 9, the screw 2 is rotatably connected to the vibrating screen 9, and the rack 7, the guide shaft 8 and the collecting box 10 are all installed on the vibrating screen 9, which makes it inconvenient to disassemble and assemble the whole.

[0042] like Figure 3As shown in the figure, a support frame 11 is provided, and the motor 1, the guide shaft 8, the rack 7, and the collection box 10 (in the embodiment without the collection box 10, the collection box 10 does not need to be installed) are installed on the support frame 11, and can be connected by bolts or welding. The lead screw is rotatably installed on the support frame 11, which can be realized by bearings or other components, and will not be elaborated here. Thus, the overall installation and disassembly can be achieved, which is convenient for operation.

[0043] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention.
