Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of material conveying devices, specifically to a material conveying device for treating fly ash solid waste. Background Technology

[0002] In the field of fly ash solid waste treatment, the dust control and uniform material conveying performance of conveying devices directly affect the environmental friendliness and efficiency of solid waste resource utilization. However, existing fly ash conveying devices generally suffer from serious dust pollution and uneven material conveying.

[0003] Existing material conveying devices suffer from significant structural defects: First, they lack dust suppression design. Traditional devices often employ open-type discharge designs. When fly ash is conveyed from a high-level silo to a low-level conveyor belt, the impact airflow generated by the drop can carry fine particles into the air. For example, during the process of fly ash falling from the storage tank to the belt conveyor, the dust generated by the free fall of material not only pollutes the working environment but may also pose a risk of dust explosion. Furthermore, the released fly ash fines require additional dust removal equipment, increasing processing costs. Second, the material distribution adjustment mechanism is insufficient. The discharge port of the conveying device is mostly a straight cylindrical structure. When fly ash falls, it tends to accumulate on one side of the conveyor belt due to gravity and inertia, leading to uneven force on the conveyor belt and causing belt deviation. For example, when a certain type of conveying device processes fly ash with large differences in moisture content, moist material accumulates on the right side of the conveyor belt due to its stickiness, while dry material tends to accumulate on the left side. This uneven distribution not only affects conveying efficiency but also exacerbates conveyor belt wear and shortens equipment lifespan.

[0004] When dealing with large-scale fly ash treatment, dust pollution and uneven transportation often affect the process of solid waste resource utilization. There is an urgent need to develop new fly ash conveying devices with dynamic dust suppression and material uniform distribution functions to improve the industry problem of unstable large-scale dust transportation. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a conveying device for treating fly ash solid waste, which solves the technical problems of serious dust pollution and uneven material conveying that are common in existing fly ash conveying devices.

[0006] According to one aspect, at least one embodiment of the present disclosure provides a conveying device for treating fly ash solid waste, comprising:

[0007] The equipment frame and the conveyor belt, wherein the conveyor belt is installed inside the equipment frame;

[0008] Side panels and fabric dust collection components, wherein the side panels are mounted on the equipment frame and the fabric dust collection components are mounted on the side panels and the equipment frame;

[0009] A discharge cleaning and scraping assembly is disposed at one end of the equipment frame;

[0010] The fabric dust collection assembly includes a feed hood, which is located on the top of the equipment frame. A fabric cover is slidably connected to the outside of the feed hood. The fabric cover is located above the conveyor belt, and a pair of connecting frames are provided on the top of the fabric cover.

[0011] As a further technical solution, a pair of ear plates are provided on the surface of the side plate, and a stud is provided at the bottom of the connecting frame. The stud is movably fitted inside the ear plate, and a pair of nuts are screwed onto the stud. The nuts are respectively attached to the top and bottom of the ear plate.

[0012] As a further technical solution, the side panel surface is provided with a notch, the top of the fabric cover is provided with a connecting pipe, one end of the connecting pipe is provided with a collection box, and a filter box is inserted and connected inside the collection box.

[0013] As a further technical solution, a centrifugal fan is provided on the outside of the equipment frame, and a telescopic pipe is connected between the air inlet end of the centrifugal fan and the bottom of the filter box.

[0014] As a further technical solution, the discharge cleaning assembly includes a pair of rotating frames, which are rotatably connected to both sides of the equipment frame, and a sliding hopper is connected between the rotating frames.

[0015] As a further technical solution, the upper surface of the sliding hopper is slidably attached to the surface of the conveyor belt, and several bolts are connected to the rotating frame by threaded screws, with anti-slip blocks provided at one end of each bolt.

[0016] As a further technical solution, one side of the fabric cover is bent inward in a V-shape.

[0017] As a further technical solution, a number of rolling rods are rotatably connected inside the equipment frame, and the rolling rods are supported at the top inside the conveyor belt.

[0018] The beneficial effects of the embodiments disclosed herein are as follows:

[0019] 1. In this disclosure, the dust collection assembly uses a sliding sleeve between the cloth cover and the feed cover to adjust the distance between the cloth cover and the conveyor belt. The V-shaped bending structure evenly distributes fly ash on the conveyor belt, avoiding accumulation and uneven stress. The design of the studs and nuts facilitates the adjustment and fixing of the cloth cover position. The negative pressure system composed of the centrifugal fan, connecting pipes, collection box, and filter box can effectively collect the dust generated during the conveying process. The filter box intercepts dust and purifies the air, solving the problem of serious dust pollution during fly ash conveying in the prior art, improving the working environment, and reducing the cost of dust removal equipment.

[0020] 2. In this disclosure, the rotating frame of the discharge cleaning component can adjust the angle of the sliding hopper so that it fits tightly with the conveyor belt, receives the material and guides it to be discharged in a concentrated manner. Bolts and anti-slip blocks lock the position of the sliding hopper to prevent vibration from affecting it. The cutting edge of the sliding hopper scrapes the residual material on the conveyor belt to prevent it from spilling back, keeping the conveying system clean. This solves the problem of uneven force on the conveyor belt caused by fly ash accumulation, improves material conveying efficiency, extends the service life of the conveyor belt, and ensures smooth material conveying and discharge.

[0034] like Figures 1-5 As shown, a conveying device for treating fly ash solid waste according to an embodiment of this disclosure is illustrated, comprising:

[0035] The equipment frame 1 and the conveyor belt 2 are installed inside the equipment frame 1;

[0036] Side plate 3 and fabric dust collection assembly 4, the side plate 3 is disposed on the equipment frame 1, and the fabric dust collection assembly 4 is disposed on the side plate 3 and the equipment frame 1;

[0037] The discharge cleaning and scraping assembly 5 is disposed at one end of the equipment frame 1;

[0038] The fabric dust collection assembly 4 includes a feed hood 4-1, which is located on the top of the equipment frame 1. A fabric cover 4-2 is slidably connected to the outside of the feed hood 4-1. The fabric cover 4-2 is located above the conveyor belt 2. A pair of connecting brackets 4-3 are provided on the top of the fabric cover 4-2. A pair of ear plates 4-4 are provided on the surface of the side plate 3. A stud 4-5 is provided at the bottom of the connecting bracket 4-3. The stud 4-5 is movably fitted inside the ear plate 4-4. A screw is screwed onto the stud 4-5. A pair of nuts 4-6 are respectively attached to the top and bottom of the ear plate 4-4. The side plate 3 has a notch 4-7 on its surface. The top of the fabric cover 4-2 is provided with a connecting pipe 4-8. One end of the connecting pipe 4-8 is provided with a collection box 4-9. A filter box 4-10 is inserted and connected inside the collection box 4-9. A centrifugal fan 4-11 is provided on the outside of the equipment frame 1. A telescopic pipe 4-12 is connected between the air inlet of the centrifugal fan 4-11 and the bottom of the filter box 4-10.

[0039] In some examples, a dust collection assembly 4 is designed to achieve uniform distribution of solid waste and dust collection. This assembly uses a feed hood 4-1 as the material inlet. An externally sliding feed hood 4-2 can be adjusted up and down along the feed hood 4-1. Through the sliding engagement of studs 4-5 within ear plates 4-4 and the locking of nuts 4-6, the distance between the feed hood 4-2 and the conveyor belt 2 can be adjusted according to the conveying volume. When fly ash solid waste falls into the feed hood 4-2, the inclined guide plate at the bottom of the feed hood 4-2 evenly distributes the material across the width of the conveyor belt 2, preventing localized accumulation. Simultaneously, a centrifugal fan 4-11 forms a negative pressure suction system with the filter box 4-10 via a telescopic pipe 4-12. The dust-laden airflow enters the collection box 4-9 through the connecting pipe 4-8. The filter layer inside the filter box 4-10 intercepts dust particles, and the purified air is discharged. The collected dust is periodically cleaned from the filter box 4-10.

[0040] The opening 4-7 at the top of the fabric cover 4-2 creates a circulation path for airflow inside the cover, enhancing dust collection and effectively capturing dust generated during the conveying process, thus improving the working environment.

[0041] like Figures 1-5As shown in the figure, the discharge cleaning and scraping assembly 5 in this embodiment includes a pair of rotating frames 5-1, which are rotatably connected to both sides of the equipment frame 1. A sliding hopper 5-2 is connected between the rotating frames 5-1. The upper end face of the sliding hopper 5-2 is slidably attached to the surface of the conveyor belt 2. Several bolts 5-3 are screwed onto the rotating frame 5-1. One end of each bolt 5-3 is provided with an anti-slip block 5-4.

[0042] In some examples, a discharge cleaning assembly 5 is designed to achieve centralized discharge and cleaning of the conveyor belt 2. This assembly is supported by rotating frames 5-1 rotatably connected to both sides of the equipment frame 1. The sliding hopper 5-2 can be adjusted in angle via the rotating frames 5-1 to ensure its upper surface is in close contact with the surface of the conveyor belt 2. When the conveyor belt 2 reaches the discharge end, the sliding hopper 5-2 receives the material and guides it downwards for centralized discharge, forming a stable discharge flow. The sliding hopper 5-2 is made of stainless steel with a polished surface to reduce frictional resistance. Its tilt angle is typically set between 45° and 60° to ensure smooth material flow. Bolts 5-3 on the rotating frames 5-1 cooperate with anti-slip blocks 5-4 to lock the position of the sliding hopper 5-2 and provide cushioning support to prevent vibration from causing changes in the contact gap.

[0043] Meanwhile, the cutting edge design of the sliding hopper 5-2 scrapes off the fine particles remaining on the surface of the conveyor belt 2. The scraped material is discharged along with the main material flow, preventing residual material from spilling when the conveyor belt 2 returns, thus keeping the conveying system clean.

[0044] By tightly fitting the adjustable sliding hopper 5-2 with the conveyor belt 2, the discharge cleaning component 5 achieves centralized material discharge and effective cleaning of the surface of the conveyor belt 2, thereby improving conveying efficiency and equipment reliability.

[0045] For example, such as Figure 1 As shown, one side surface of the fabric cover 4-2 is bent inward in a V-shape.

[0046] In some examples, the V-shaped structure significantly enhances the leveling effect. The fabric hood bends inward in a V-shape on one side, and its unique geometry plays multiple roles in the conveying of fly ash solid waste. When the solid waste falls from the feed hood into the fabric hood, the V-shaped bend acts like a guide plate, dispersing the concentrated material to both sides. Simultaneously, the material's own weight and the friction generated by the conveyor belt create a lateral thrust, prompting the material to spread rapidly on the conveyor belt. Compared to a planar structure, the V-shaped design extends the contact path between the material and the fabric hood. As the material slides down the slope, it is continuously compressed and spread out, breaking up and leveling any accumulated lumps or piles of solid waste. This effectively prevents material from spilling onto the equipment frame or the ground, reducing material waste and the intensity of subsequent cleanup work. It ensures stable and uniform conveying of solid waste on the conveyor belt, providing a good foundation for subsequent processing steps.

[0047] For example, such as Figure 3 As shown, a number of rolling rods 6 are rotatably connected inside the equipment frame 1, and the rolling rods 6 are supported on the top of the conveyor belt 2.

[0048] In some examples, multiple rollers 6 are provided to support the conveyor belt 2 and prevent deformation of the conveyor belt 2.

[0049] In actual use: Fix the equipment frame 1, install the conveyor belt 2 inside the equipment frame 1, fix the side plate 3 to the equipment frame 1, install the feed hood 4-1 of the fabric dust collection assembly 4 on the top of the equipment frame 1, slide the fabric hood 4-2 onto the outside of the feed hood 4-1 and above the conveyor belt 2, the stud 4-5 at the bottom of the connecting frame 4-3 passes through the ear plate 4-4 of the side plate 3, and is fixed at the upper and lower ends of the ear plate 4-4 with nuts 4-6, the connecting pipe 4-8 of the fabric hood 4-2 is connected to the notch 4-7 of the side plate 3, the collection box 4-9 is installed at one end of the connecting pipe 4-8, and the filter box 4-10 is inserted into the collection box 4. Inside -9, the centrifugal fan 4-11 is connected to the bottom of the filter box 4-10 through the telescopic pipe 4-12. The rotating frame 5-1 of the discharge cleaning component 5 is rotatably connected to both sides of the equipment frame 1. The sliding hopper 5-2 is connected between the rotating frame 5-1. The bolt 5-3 passes through the rotating frame 5-1 and is screwed to connect the anti-slip block 5-4. When in use, fly ash enters the cloth cover 4-2 from the feed hood 4-1. The V-shaped structure of the cloth cover 4-2 disperses the material to the conveyor belt 2. The centrifugal fan 4-11 collects dust through the filter box 4-10. When the conveyor belt 2 runs to the discharge end, the sliding hopper 5-2 receives the material and cleans the residue on the conveyor belt 2.
