A high-efficiency dispersing device for phosphogypsum processing

Abstract

This utility model discloses a high-efficiency dispersing device for phosphogypsum processing, including a body and supporting legs. This utility model employs a bearing plate, spikes, a drive shaft, and baffles. During the dispersing process of phosphogypsum, it first falls onto the bearing plates at different positions. The spikes on the corresponding crushing plates then approach and break up any clumps of phosphogypsum. After multiple crushing operations, the phosphogypsum falls into the area where the drive shaft is located. Through the continuous rotation and collision of the striking balls, striking rods, and crushing blades on its surface, the broken phosphogypsum is more thoroughly dispersed. Furthermore, due to the baffles, personnel can intermittently add phosphogypsum, avoiding excessive amounts of phosphogypsum that could lead to insufficient dispersing or inadequate contact during dispersal. This improves the overall processing quality and offers advantages such as multi-stage processing, excellent dispersing effect, and thorough dispersal.

Description

Technical Field

[0001] This utility model relates to the field of phosphogypsum technology, and more specifically, to a high-efficiency dispersing device for phosphogypsum processing. Background Technology

[0002] Phosphogypsum is a powdery solid waste discharged during the production of phosphate fertilizer and phosphoric acid. It is also used in the production of building materials. Phosphogypsum will clump when it gets damp. When using phosphogypsum to make building materials, powdered phosphogypsum is required. Therefore, clumped phosphogypsum needs to be broken up before use.

[0003] The existing public technology application number is CN201621228604.2, which discloses a phosphogypsum dispersing device, including a shell, a dispersant disposed inside the shell, and a frame disposed outside the shell to support the entire device. The shell is a hollow cylindrical shape, with an inlet on one side of the upper part of the shell and an outlet on the lower side of the shell away from the inlet. The dispersant includes a drive shaft that runs through the shell, double helical blades fixedly disposed on the drive shaft and located inside the shell, and a sprocket fixedly disposed at one end of the drive shaft and located outside the shell. The sprocket is connected to a motor and rotates under the drive of the motor.

[0004] However, the above-mentioned patent still has certain drawbacks in use: its overall dispersing structure is relatively simple, and it is not very effective in treating clumps of phosphogypsum. Moreover, it enters the machine in large quantities each time for processing, which results in the phosphogypsum that has accumulated not being processed thoroughly enough, thus affecting the overall dispersing quality and having certain limitations.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a high-efficiency dispersing device for phosphogypsum processing, which has the advantages of multiple processing, good dispersing effect, and thorough dispersing, thereby solving the problems mentioned in the background technology.

[0007] (II) Technical Solution To achieve the advantages of multiple processing steps, good dispersion effect, and thorough dispersion, the specific technical solution adopted by this utility model is as follows: A high-efficiency dispersing device for processing phosphogypsum includes a body and supporting legs. Several sets of bearing plates are staggered and inclinedly installed at the top of the inner surface of the body. A sealing groove is opened in the material feeding area of ​​the surface of the bearing plate. A baffle is slidably connected inside the sealing groove. A second cylinder is connected to the bottom of the baffle and is installed at the bottom of the bearing plate. A crushing plate is inclinedly installed directly above the bearing plate. Several sets of spikes are evenly installed at the bottom of the crushing plate. The density of the spikes on the surface of the multiple sets of crushing plates gradually increases and their size gradually decreases. A first cylinder is connected to the top of the crushing plate. The first cylinder is located at the top of the inner surface of the body and at the bottom of the bearing plate above.

[0008] Furthermore, a drive shaft is installed below the support plate at the bottom of the machine body, with one end of the drive shaft passing through one side of the machine body and connected to a motor.

[0009] Furthermore, several sets of striking rods and crushing blades are evenly mounted around the surface of the drive shaft, and a striking ball is welded to the front end of each striking rod.

[0010] Furthermore, a feed pipe is installed at an angle at the top of one side surface of the machine body.

[0011] Furthermore, a discharge port is provided at the middle position of the bottom of the machine body.

[0012] Furthermore, several sets of support legs are symmetrically installed on both sides of the bottom of the machine body.

[0013] Furthermore, a vibration motor is installed on the outer surface of the machine body.

[0014] Furthermore, the discharge area of ​​the feed pipe is located between the crushing plate and the bearing plate, and the two sides of the bearing plate are embedded into the inner wall of the machine body.

[0015] (III) Beneficial Effects Compared with the prior art, this utility model provides a high-efficiency dispersing device for phosphogypsum processing, which has the following beneficial effects: This invention employs a support plate, spikes, a drive shaft, and baffles. During the dispersing process of phosphogypsum, it first falls onto the support plates at different locations. The spikes on the corresponding crushing plates then break up any clumps of phosphogypsum, preventing excessively large clumps from affecting subsequent dispersing quality. The phosphogypsum after multiple crushing stages falls into the area of ​​the drive shaft. Through the continuous rotation and collision of the impact balls, impact rods, and crushing blades on the drive shaft's surface, the broken phosphogypsum is more thoroughly dispersed, improving overall processing quality. Furthermore, the baffles allow for intermittent addition of phosphogypsum, preventing excessive amounts from flooding in simultaneously and causing insufficient dispersing or inadequate contact, thus improving overall processing quality and facilitating better use. It offers advantages such as multi-stage processing, excellent dispersing effect, and thorough dispersing. Attached Figure Description

[0020] According to an embodiment of the present invention, a high-efficiency dispersing device for phosphogypsum processing is provided.

[0021] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4 As shown, a high-efficiency dispersing device for phosphogypsum processing according to an embodiment of the present invention includes a body 1 and supporting legs 12. Several sets of bearing plates 5 are staggered and inclinedly installed at the top of the inner surface of the body 1. A sealing groove 8 is provided in the material feeding area of ​​the bearing plate 5. A baffle 17 is slidably connected inside the sealing groove 8. A second cylinder 16 is connected to the bottom of the baffle 17 and is installed at the bottom of the bearing plate 5. A crushing plate 2 is inclinedly installed directly above the bearing plate 5. Several sets of spikes 3 are evenly installed at the bottom of the crushing plate 2. The density of spikes 3 on the surface of the crushing plate 2 gradually increases and their size gradually decreases. A first cylinder 4 is connected to the top of the crushing plate 2. The first cylinder 4 is located at the top of the machine body 1 and at the bottom of the upper support plate 5. The support plate 5 is installed with multiple sets of support plates staggered at a 15° angle on the inner wall of the machine body 1, embedded in grooves on both sides of the machine body 1 (e.g., embedding depth 20mm), and fixed with T-bolts. The crushing plate 2 is made of 6mm thick manganese steel plate and is connected to the first cylinder 4 (stroke 100mm, thrust 500N). Driven by a cylinder fixed to the top of the machine body 1 and the bottom of the upper support plate 5, the piston rod is hinged to the crushing plate 2 (pin diameter 12mm); Spike 3 layout: Spikes 3 are made of hard alloy (YG8) welded to the crushing plate 2, the upper spikes 3 have a diameter of 10mm and a spacing of 50mm, the lower spikes have a diameter of 8mm and a spacing of 30mm, and the density increases from 20 spikes / m² to 40 spikes / m²; The support plate 5 and the crushing plate 2 form a multi-stage crushing zone, the first cylinder 4 drives the crushing plate 2 to reciprocate (speed 0-20 times / minute), and the baffle 17 is driven by the second cylinder 4. Driven by cylinder 16 (stroke 50mm), the opening size of the sealing groove 8 is controlled (opening rate 0-100%); graded crushing: multi-stage spike 3 density increasing design, gradually crushes lumps larger than 50mm to less than 10mm, improving crushing efficiency; flow control: baffle 17 adjusts the feed rate to ensure the crushing amount each time and avoid overload. All models, materials, dimensions, etc. described in this application can be adjusted by personnel in the later according to the actual situation. They can be selected and matched by themselves without affecting the structure and function implementation. No further details are provided here.

[0022] like Figure 1 As shown, a drive shaft 13 is installed at the bottom of the machine body 1 below the support plate 5. One end of the drive shaft 13 passes through one side of the machine body 1 and is connected to the motor 10. The drive shaft 13 is 60mm in diameter and is supported on both sides of the machine body 1 by self-aligning roller bearings (model 22212). The shaft end is connected to the motor 10 (power 15kW, speed 1450r / min) by a coupling, and the coaxiality is ≤0.05mm.

[0023] like Figure 1 As shown, several sets of striking rods 14 and crushing blades 9 are evenly installed around the surface of the drive shaft 13. A striking ball 15 is welded to the front end of each striking rod 14. The striking components are as follows: the striking rods 14 (20mm in diameter) are spirally distributed (100mm pitch), with a φ30mm striking ball 15 (made of wear-resistant cast iron) welded to the front end; the crushing blades 9 (5mm thick) are installed at a 30° angle with a blade angle of 45°. When the drive shaft 13 rotates, the striking rods 14 and the crushing blades 9 form a composite dispersing field. The impact force of the striking ball 15 is ≥50N, the blade linear velocity is ≥20m / s, the material stays in the area of ​​the drive shaft 13 for 3-5 seconds, and the number of impacts is ≥20 times / second. High-efficiency dispersing: the combined action of striking and shearing disperses particles smaller than 10mm to ≤2mm, improving the dispersing rate. Wear-resistant design: the striking ball 15 and the blades are reinforced with a wear-resistant layer (3mm thick), ensuring a long service life.

[0024] like Figure 1 As shown, a feed pipe 6 is installed at an angle on the top of one side surface of the machine body 1. The feed pipe 6 is a seamless steel pipe with a diameter of 150mm, which is welded to the top of the machine body 1 at an angle of 45°. The inlet is provided with a flange (PN10), and the outlet is aligned with the gap between the upper support plate 5 and the crushing plate 2 (e.g., a spacing of 100mm). A guide plate is provided inside the pipe (e.g., an inclination angle of 30°). The guide plate of the feed pipe 6 makes the material evenly distributed on the support plate 5.

[0025] like Figure 1 As shown, a discharge port 11 with a diameter of 200mm is provided at the bottom center of the machine body 1. The outlet is connected to the conveying pipe and is equipped with a pneumatic butterfly valve (diameter 200mm). The butterfly valve of the discharge port 11 is interlocked with the drive shaft 13 and automatically closes when the machine stops to prevent material accumulation.

[0026] like Figure 1 As shown, several sets of support legs 12 are symmetrically installed on both sides of the bottom of the machine body 1. The machine body 1 is welded from Q345B steel plate. The feed pipe 6 is reinforced with ribs (thickness 8mm) at the connection. Four sets of support legs 12 are welded on both sides of the bottom of the machine body 1. The legs are 300mm high. Adjustable feet (adjustment range 0-50mm) are installed at the bottom and fixed to the ground with M20 expansion bolts.

[0027] like Figure 1 As shown, a vibration motor 7 is installed on the outer surface of the machine body 1. The vibration motor 7 (model YZU-10-6) is fixed to the middle of the outer side of the machine body 1 with bolts. The axis of the motor 7 is perpendicular to the machine body 1. The vibration frequency is 600 times / minute and the amplitude is 1-2mm. The adjustable feet of the support legs 12 ensure that the levelness of the machine body 1 is ≤0.5°. The horizontal vibration generated by the vibration motor 7 is transmitted to the support plate 5 through the machine body 1 to prevent phosphogypsum from accumulating. Anti-clogging design: The vibration motor 7 causes the support plate 5 to vibrate slightly, which increases the sliding speed of phosphogypsum and avoids clumping and accumulation.

[0028] like Figure 1 and Figure 3 As shown, the discharge area of ​​the feed pipe 6 is located between the crushing plate 2 and the support plate 5, and the support plate 5 is embedded in the inner wall of the machine body 1 on both sides. The support plate 5 is embedded 20mm into the inner wall of the machine body 1 to form an annular baffle to prevent material splashing. In the graded crushing stage: phosphogypsum falls from the feed pipe 6 into the upper support plate 5, and the second cylinder 16 controls the baffle 17 to open 1 / 3, with a feed amount of 3-5kg each time; the first cylinder 4 drives the crushing plate 2 to move downward, and the spikes 3 puncture the lumps, crushing lumps larger than 50mm into lumps smaller than 10mm. The vibration motor 7 starts synchronously to assist the material to slide down; after crushing, the material falls into the middle support plate 5 through the sealing groove 8, and the crushing process is repeated. The density of spikes 3 increases to 30 spikes / m², and the material is crushed to less than 5mm. In the high-speed dispersing stage, the material falls into the area of ​​the drive shaft 13, and the motor 10 drives the striking rod 14 and the crushing blade 9 to rotate at high speed. The striking ball 15 impacts the material, and the blades shear and refine the material. The dispersed material (≤2mm) is discharged through the discharge port 11. The butterfly valve of the discharge port 11 is opened periodically, and 5-8kg is discharged each time. Through the multi-stage crushing-dispersing composite system and vibration-assisted feeding, this device achieves efficient dispersing of phosphogypsum. It has significant advantages, especially in the treatment of high-humidity agglomerated phosphogypsum, meeting the stringent requirements of powder fineness in building material production, while reducing energy consumption and maintenance costs.

[0029] Working Principle: In actual use, personnel can add clumps of dried phosphogypsum through the feed pipe 6 at the top side of the machine body 1. The added phosphogypsum will naturally slide down the inclined pipe to the support plate 5. Because the support plate 5 has a baffle 17 on its side, the phosphogypsum will be blocked on the surface of the support plate 5. Then, the operation of the first cylinder 4 will drive the crushing plate 2 to move downwards, causing the spikes 3 on the surface of the crushing plate 2 to approach the surface of the support plate 5. The approaching spikes 3 will then puncture the phosphogypsum, breaking up the clumps. After crushing, the baffle 17 will fall with the operation of the second cylinder 16, and the crushed phosphogypsum will naturally fall onto the support plate 5 below for a secondary crushing operation. Because the density and size of the spikes 3 on the crushing plate 2 corresponding to the lower support plate 5 are increased, they can further crush the clumps. The crushing process is more compact, improving the overall crushing quality and facilitating better dispersal for subsequent use. Furthermore, a vibration motor 7 is installed on the side of the machine body 1. The vibration generated by the motor 7 agitates the residual phosphogypsum on the support plate 5, allowing it to fall more thoroughly and reducing residue. The phosphogypsum, after multiple crushing operations, falls to the drive shaft 13. Through the continuous rotation and collision of the striking balls 15, striking rods 14, and crushing blades 9 on the surface of the drive shaft 13, the crushed phosphogypsum is more thoroughly dispersed, improving the overall processing quality. Due to the baffle 17, personnel can intermittently add phosphogypsum, preventing excessive amounts from flowing in simultaneously, which could lead to insufficient dispersal or inadequate contact for dispersion. This improves the overall processing quality and facilitates better use. The device as a whole has the advantages of multi-processing, good dispersal effect, and thorough dispersal.
