Description

Technical Field

[0001] This utility model belongs to the field of phosphate rock technology, and in particular to a conveying device for phosphate rock. Background Technology

[0002] Phosphate rock, as an important non-metallic mineral resource, is widely used in fertilizer production, chemical raw materials, and many other fields. In the processing and transportation of phosphate rock, conveying devices are key equipment for achieving continuous material transfer. Traditional phosphate rock conveying systems typically consist of belt conveyors and silo structures, and their core function is to stably transport phosphate rock from the storage end to subsequent processing steps or stockpiling areas.

[0003] However, in actual use, due to the characteristics of phosphate rock such as uneven particle size, easy agglomeration, and poor flowability, traditional conveying devices are prone to material accumulation and blockage during the feeding process, which seriously affects the conveying efficiency and system stability. Therefore, there is an urgent need for a phosphate rock conveying device with anti-blockage and automatic quantitative feeding functions. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a conveying device for phosphate rock.

[0005] The purpose of this utility model is achieved through the following technical solution: a conveying device for phosphate rock, comprising a phosphate rock conveying assembly, the phosphate rock conveying assembly including a belt conveyor and a conveying hopper disposed above one end of the belt conveyor, a tail cover being installed on the outer wall of the end of the belt conveyor near the conveying hopper, a discharge anti-blocking component being provided in the inner cavity of the conveying hopper, the discharge anti-blocking component including a unidirectional rotating phosphate rock quantitative discharge anti-blocking plate installed in the conveying hopper, a servo motor installed on the outer wall of the conveying hopper and driving the phosphate rock quantitative discharge anti-blocking plate to rotate unidirectionally in both forward and reverse directions in the conveying hopper, and a support block located below the phosphate rock quantitative discharge anti-blocking plate and welded to the inner wall of the conveying hopper, the support block being located on the inner wall of the end of the conveying hopper away from the tail cover, the rotation of the phosphate rock quantitative discharge anti-blocking plate can spread out the phosphate rock accumulated on the top surface of the belt conveyor directly below the conveying hopper, and a cleaning component for cleaning the belt surface of the belt conveyor is provided inside the tail cover.

[0006] In a preferred embodiment, an auxiliary support component is provided above the tail cover and on the outer wall of the conveying and feeding hopper. The free end of the auxiliary support component extends to the end of the conveying and feeding hopper that supports the phosphate rock quantitative feeding anti-blocking plate away from the support block.

[0007] In a preferred embodiment of this scheme, the auxiliary support assembly includes a U-shaped frame welded to the outer wall of the conveying hopper, a hydraulic cylinder fixed to the inner wall of the U-shaped frame, a piston rod connected to the free end of the hydraulic cylinder, and a rectangular plug plate fixed to the free end of the piston rod.

[0008] In this preferred embodiment, the inner wall of the conveying and feeding bin near the U-shaped frame is provided with a rectangular insertion interface for inserting a rectangular insertion plate, so that the oil cylinder and piston rod drive the rectangular insertion plate to be inserted into the conveying and feeding bin through the rectangular insertion interface to support the quantitative feeding and anti-blocking plate of phosphate rock.

[0009] In a preferred embodiment, the cleaning component includes a cleaning brush and a cleaning dust scraper block respectively disposed on the inner wall of the tail cover, wherein both the cleaning brush and the cleaning dust scraper block abut against the surface of the belt conveyor.

[0010] In a preferred embodiment, the tail cover is rotatably mounted on the inner wall of the end facing the corner of the belt conveyor, and the cleaning brush is fixed to the circumference of the rotating shaft.

[0011] In a preferred embodiment, a fixing plate is fixed to the inner top wall of the tail cover, and an extension plate is longitudinally extended and retracted to the bottom end of the belt of the belt conveyor. The cleaning and dust scraping cotton block is adhered to the bottom surface of the extension plate.

[0012] In a preferred embodiment, the extension plate is welded to a plug-in inner plate at one end facing the fixed plate, and the fixed plate has a plug-in inner cavity for positioning and plugging the plug-in inner plate.

[0013] In this preferred embodiment, multiple compression springs are fixedly installed at equal intervals in the fixed plate. The insertable inner plate is inserted into the fixed plate and abuts against the compression springs, so that the insertable inner plate is driven to extend and retract within the fixed plate under the action of the compression springs. This causes the compression springs to elastically push the extension plate, so that the cleaning and dust-scraping cotton block abuts against the belt surface of the belt conveyor.

[0014] In a preferred embodiment, conveyor rollers are rotatably mounted inside both ends of the belt conveyor, and a conveyor motor is installed at one end of one of the conveyor rollers.

[0015] The beneficial effects of this utility model are:

[0016] 1) A servo motor drives the phosphate rock metering anti-blocking plate to rotate unidirectionally in both directions within the conveyor hopper, ensuring orderly dumping of the phosphate rock. An auxiliary support assembly is located below the phosphate rock metering anti-blocking plate and is positioned away from the conveyor belt direction to prevent the plate from exceeding its unidirectional rotation stroke. The servo motor controls the unidirectional rotation of the phosphate rock metering anti-blocking plate, ensuring consistent phosphate rock volume each time it is dumped, thus avoiding material accumulation and blockage problems caused by free fall in traditional devices.

[0017] 2) The rotation of the phosphate rock quantitative feeding anti-blocking plate can spread out the phosphate rock piled up on the top surface of the belt conveyor directly below the feeding hopper. Since it can effectively prevent material accumulation, it reduces equipment wear and failure rate, thereby extending the overall service life of the equipment, reducing downtime caused by blockage and uneven material distribution, and reducing maintenance frequency and cost.

Detailed Implementation

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] See Figures 1-5This utility model provides a conveying device for phosphate rock, including a phosphate rock conveying assembly 1. The phosphate rock conveying assembly 1 includes a belt conveyor 2 and a conveying and unloading bin 3 disposed above one end of the belt conveyor 2. A tail cover 7 is installed on the outer wall of the end of the belt conveyor 2 near the conveying and unloading bin 3. A feeding anti-blocking component 10 is disposed in the inner cavity of the conveying and unloading bin 3. The feeding anti-blocking component 10 includes a phosphate rock quantitative feeding anti-blocking plate 6 unidirectionally rotatable in the conveying and unloading bin 3, a servo motor 9 installed on the outer wall of the conveying and unloading bin 3 and driving the phosphate rock quantitative feeding anti-blocking plate 6 to rotate unidirectionally in both forward and reverse directions in the conveying and unloading bin 3, and a support bar 13 located below the phosphate rock quantitative feeding anti-blocking plate 6 and welded to the inner wall of the conveying and unloading bin 3. The support bar 13 is located on the inner wall of the end of the conveying and unloading bin 3 away from the tail cover 7, such that the support bar 13 is arranged away from the conveying direction of the belt conveyor 2. When the servo motor 9 drives the phosphate rock quantitative feeding anti-blocking plate 6 to rotate clockwise in the conveying hopper 3 away from the conveying direction of the belt conveyor 2, the phosphate rock quantitative feeding anti-blocking plate 6 pours the phosphate rock it carries onto the belt conveyor 2 directly below the conveying hopper 3, allowing the belt conveyor 2 to transport the phosphate rock out. At the same time, as the phosphate rock quantitative feeding anti-blocking plate 6 rotates, it can spread out the phosphate rock accumulated on the top surface of the belt conveyor 2 directly below the conveying hopper 3, which helps to prevent blockage and accumulation. When the phosphate rock quantitative feeding anti-blocking plate 6 resets and rotates counterclockwise, the auxiliary support component 13 can prevent the phosphate rock quantitative feeding anti-blocking plate 6 from exceeding the one-way rotation stroke, so that the phosphate rock quantitative feeding anti-blocking plate 6 resets and remains in a horizontal state. The tail cover 7 is equipped with a cleaning component for cleaning the belt surface of the belt conveyor 2.

[0026] In this embodiment, an auxiliary support component 11 is provided above the tail cover shell 7 and on the outer wall of the conveying and feeding bin 3. The free end of the auxiliary support component 11 extends to the end of the conveying and feeding bin 3 that supports the phosphate rock quantitative feeding anti-blocking plate 6 away from the support block 13.

[0027] In this embodiment, the auxiliary support assembly 11 includes a U-shaped frame 8 welded to the outer wall of the conveying and unloading hopper 3, a hydraulic cylinder 14 fixed to the inner wall of the U-shaped frame 8, a piston rod 15 connected to the free end of the hydraulic cylinder 14, and a rectangular plug plate 16 fixed to the free end of the piston rod 15.

[0028] In this embodiment, a rectangular insertion interface 12 is provided on the inner wall of the conveying and feeding bin 3 near the U-shaped frame 8 for inserting a rectangular insertion plate 16. This allows the hydraulic cylinder 14 and piston rod 15 to drive the rectangular insertion plate 16 through the rectangular insertion interface 12 into the conveying and feeding bin 3 to support the phosphate rock quantitative feeding anti-blocking plate 6. This further supports the phosphate rock quantitative feeding anti-blocking plate 6, preventing the phosphate rock on it from being crushed. When it is necessary to pour out the phosphate rock, the hydraulic cylinder 14 and piston rod 15 drive the rectangular insertion plate 16 to retract and push it back from the rectangular insertion interface 12.

[0029] In this embodiment, the cleaning component includes a cleaning brush 18 and a cleaning dust scraper 20 respectively disposed on the inner wall of the tail cover 7. Both the cleaning brush 18 and the cleaning dust scraper 20 abut against the belt surface of the belt conveyor 2.

[0030] In this embodiment, a rotating shaft 17 is rotatably installed on the inner wall of the end of the tail cover 7 facing the corner of the belt conveyor 2, and a cleaning brush 18 is fixed to the periphery of the rotating shaft 17.

[0031] In this embodiment, a fixing plate 19 is fixed to the inner top wall of the tail cover 7. An extension plate 21 is longitudinally extended and retracted to the bottom end of the belt of the belt conveyor 2. The cleaning and dust scraping cotton block 20 is adhered to the bottom surface of the extension plate 21.

[0032] In this embodiment, an inner plug-in plate 22 is welded to one end of the extension plate 21 facing the fixed plate 19, and an inner plug-in cavity 23 is provided in the fixed plate 19 for positioning and plugging the inner plug-in plate 22.

[0033] In this embodiment, multiple compression springs 24 are fixedly installed at equal intervals in the fixed plate 19. The insert inner plate 22 is inserted into the fixed plate 19 and abuts against the compression springs 24, so that the insert inner plate 22 is driven to extend and retract in the fixed plate 19 under the action of the compression springs 24, so that the compression springs 24 elastically push the extension plate 21, so that the cleaning dust scraper 20 abuts against the belt surface of the belt conveyor 2.

[0034] In this embodiment, conveyor rollers 5 are rotatably installed inside both ends of the belt conveyor 2, and a conveyor motor 4 is provided at one end of one of the conveyor rollers 5.

[0035] Working principle

[0036] This conveying device for phosphate rock allows raw phosphate rock to enter the conveying hopper 3 and accumulate on the phosphate rock metering anti-blocking plate 6, awaiting periodic dumping onto the belt conveyor 2 for transport. The PLC in the external control cabinet controls the servo motor 9 to start, driving the phosphate rock metering anti-blocking plate 6 to rotate unidirectionally clockwise towards the belt conveyor 2 at a set angle. During this process, the phosphate rock metering anti-blocking plate 6 dumps the phosphate rock accumulated on it onto the belt conveyor 2 below. At the same time, due to the swinging of the phosphate rock metering anti-blocking plate 6, the phosphate rock already accumulated on the surface of the belt below it will be spread out, preventing local accumulation that could cause jamming or blockage.

[0037] After one tilting is completed, the PLC in the external control cabinet controls the servo motor 9 to reverse, driving the phosphate rock quantitative feeding anti-blocking plate 6 to reset and rotate counterclockwise, returning to the horizontal position. At this time, the support block 13 welded to the inner wall of the conveying and feeding bin 3 plays a limiting role on the phosphate rock quantitative feeding anti-blocking plate 6, preventing it from rotating excessively and ensuring that it maintains a stable horizontal state after each reset, preparing for the next round of tilting.

[0038] When the phosphate rock metering anti-blocking plate 6 carries a large amount of phosphate rock, in order to prevent it from deforming or breaking due to gravity, the external auxiliary support component 11 plays a role. The PLC control cylinder 14 in the external control cabinet drives the piston rod 15 to extend, which drives the rectangular plug plate 16 to insert into the rectangular plug interface 12 on the inner wall of the conveying and feeding bin 3. After insertion, the rectangular plug plate 16 supports the side of the anti-blocking plate 6 away from the fixed end, enhancing its load-bearing capacity. When it is necessary to swing and tilt again, the cylinder 14 drives the plug plate to retract, releasing the movement space of the anti-blocking plate 6.

[0039] During the continuous operation of the belt conveyor 2, two cleaning components inside the tail cover 7 work synchronously to remove residual phosphate rock powder or particles from the belt surface: the rotating shaft 17 is installed inside the tail cover 7, and the cleaning brush 18 is fixed to the circumference of the rotating shaft. As the belt runs, the brush contacts the belt surface and rotates to remove the attached material. The fixing plate 19 is connected to the extension plate 21, and the bottom is pasted with a dust scraper 20. The insert inner plate 22 is inserted into the insert inner cavity 23 and provides elastic pressure through multiple compression springs 24. The compression springs 24 push the extension plate 21 downward so that the dust scraper 20 is always in close contact with the belt surface to scrape off fine dust.

[0040] The conveyor rollers 5 are installed at both ends of the belt conveyor 2. One end is connected to the conveyor motor 4. The PLC in the external control cabinet controls the conveyor motor 4 to drive the conveyor rollers 5 to rotate, which drives the belt to circulate and stably transport the phosphate rock poured on the belt to the next process or storage area.

It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge.
