Abstract
Description
Technical Field
[0001] This utility model relates to the field of solid waste treatment technology, and in particular to a light material conveying mechanism for a water flotation machine. Background Technology
[0002] A water flotation machine is a device used for the recycling of aggregates from construction waste. It works by using the difference in buoyancy between materials with different densities in water. Materials with a density less than that of water have a buoyancy greater than their weight and will float on the surface of the water, while materials with a density greater than that of water have a buoyancy less than their weight and will sink.
[0003] Existing water flotation machines use belt conveyors for conveying light materials. These conveyors lift and transport floating materials such as wood and beverage bottles from the water surface. However, during transport, some silt and particulate impurities can adhere to the conveyor belt, causing it to jam and reducing the efficiency of the water flotation machine. Simultaneously, impurities such as silt and dust move with the water flow to below the conveyor, accumulating over time and clogging the conveying inlet. This slows the water flow at the conveyor, further reducing the machine's efficiency. Utility Model Content
[0004] The technical problem to be solved by this utility model is: in order to solve the problem of low working efficiency of light material conveying mechanism, this utility model provides a light material conveying mechanism for water flotation machine, which uses a rotating screen cylinder to realize the sorting and conveying of light materials, replacing the belt conveyor mode, reducing the probability of jamming of light material conveying mechanism, and indirectly improving the working efficiency of light material conveying mechanism.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a light material conveying mechanism for a water flotation machine, including a circulating water tank and a screen cylinder. The screen cylinder is rotatably installed on the top of the circulating water tank, and part of the screen cylinder is located in the water. A conveying plate is fixedly installed on one side of the circulating water tank, and the conveying plate is located on one side of the screen cylinder.
[0006] The screen cylinder includes multiple scraper assemblies arranged circumferentially along the arc surface of the screen cylinder. End caps are fixedly installed at both ends of the scraper assemblies. The rotating scraper assemblies transport light materials in the circulating water tank to the conveying plate. Thus, the rotating screen cylinder drives the scraper assemblies to repeatedly enter and exit water, thereby achieving the effect of conveying light materials. Multiple scraper assemblies evenly transport materials, reducing the probability of material accumulation causing the screen cylinder to jam, indirectly improving the working efficiency of the light material conveying mechanism. The end caps can prevent mud and sand from seeping into the bearings, thereby avoiding the phenomenon of transmission structure jamming.
[0007] Furthermore, the scraper assembly includes a connecting plate, a connector, and a scraper; the connector is V-shaped, one end of the connecting plate is fixedly connected to one inclined side of the connector, and the other side of the connector is fixedly connected to the scraper; the long side of the connecting plate and the long side of the scraper are arranged parallel to the axis of the sieve cylinder, the scraper extends outward along the circumference of the sieve cylinder, and the scraper is inclined to the horizontal direction; thus, the connector makes the connecting plate and the scraper form an angle, which can effectively store the scraped material.
[0008] Furthermore, to maximize the collection efficiency of the scraper assembly, the connecting plate is placed at an angle, and the connecting plate is fixedly connected to the connector of the adjacent scraper assembly, so that multiple scraper assemblies are connected end to end to close and form the arc surface of the screen cylinder; thus, the scraper assembly is placed at an angle relative to the horizontal plane, and the adjacent scraper assemblies form an angle. When moving circumferentially, the light material picked up is accumulated in the angle, ensuring that the picked-up material will not fall easily while picking up the material.
[0009] Furthermore, in order to reduce the rotational resistance of the screen cylinder, the side of the connecting plate is provided with multiple water passage holes, which are arranged in an axial array. Thus, when water flows through the screen cylinder, it passes through the water passage holes and passes through the screen cylinder, reducing the resistance of the connecting plate to the water flow, thereby ensuring that the screen cylinder can rotate stably. At the same time, it achieves the effect of draining light materials being scooped up, reducing the weight conveyed by the screen cylinder, thereby ensuring the stable rotation of the screen cylinder.
[0010] Furthermore, the circulating water tank is provided with water outlets on both sides, and the water outlets are located below the screen cylinder.
[0011] Furthermore, to prevent sediment from clogging the outlet, a filter barrel is installed inside the circulating water tank, positioned diagonally below the screen cylinder. The end face of the filter barrel is crescent-shaped, and its short arc surface is concentric with the screen cylinder, with filter holes evenly distributed on the short arc surface. Both ends of the filter barrel are connected to the outlet. Thus, after the water flows through the screen cylinder, it enters the filter barrel through the filter holes and is discharged from the outlet, thereby preventing sediment from clogging the outlet and indirectly ensuring the stable operation of the screen cylinder.
[0012] Furthermore, to prevent sediment from accumulating at the filter barrel, the scraper contacts the short arc surface of the filter barrel; thus, the rotation of the screen barrel causes the scraper to scrape across the short arc surface of the filter barrel, carrying away the sediment and cleaning the filter holes.
[0013] Furthermore, the connecting plate is a straight plate.
[0014] Furthermore, the connecting plate is an arc-shaped plate.
[0015] The beneficial effects of this utility model are that the light material conveying mechanism of the water flotation machine of this utility model is equipped with a scraper assembly. The rotating screen cylinder drives the scraper assembly to repeatedly enter and exit water, thereby achieving the effect of conveying light materials. It replaces the belt conveyor mode, reduces the probability of jamming of the light material conveying mechanism, and indirectly improves the working efficiency of the light material conveying mechanism. The end cover can prevent mud and sand from seeping into the bearing, thereby avoiding the phenomenon of transmission structure jamming.
[0016] The light material conveying mechanism of this utility model water flotation machine is equipped with a filter barrel. After the water flows through the screen cylinder, it enters the interior of the filter barrel through the filter holes and then exits from the outlet, thereby preventing mud and sand from clogging the outlet and indirectly ensuring the stable operation of the screen cylinder. This makes the water flow at the light material conveying mechanism stable, thus ensuring the working efficiency of the water flotation machine. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0024] Example 1:
[0025] like Figures 1-4 The diagram shows the preferred embodiment of this utility model, a light material conveying mechanism for a water flotation machine, including a circulating water tank 1 and a screen cylinder, as shown in the reference diagram. Figure 1The screen cylinder is rotatably installed on the top of the circulating water tank 1, with part of the screen cylinder located in the water. A conveyor plate 12 is fixedly installed on one side of the circulating water tank 1. The conveyor plate 12 is located on one side of the screen cylinder, and the extended line of the long side of the conveyor plate 12 is tangent to the arc surface of the screen cylinder.
[0026] Reference Figure 2 The screen cylinder includes multiple scraper assemblies 22, which are arranged circumferentially along the arc surface of the screen cylinder. End caps 21 are fixedly installed at both ends of each scraper assembly 22. A rotating shaft 23 is fixedly installed in the center of each end cap 21, passing through the end cap 21. The rotating scraper assembly 22 transports light materials from the circulating water tank 1 to the conveying plate 12. Figure 2 (Arrow a in the diagram indicates the direction of light material transport, and arrow b indicates the direction of water flow.) The rotating shaft 23 is rotatably connected to the circulating water tank 1. One end of the rotating shaft 23 is equipped with a drive mechanism, which uses an existing power mechanism and will not be described in detail here. Thus, the rotating screen cylinder drives the scraper assembly 22 to repeatedly enter and exit water, thereby achieving the effect of transporting light materials. Multiple scraper assemblies 22 transport materials evenly, reducing the probability of material accumulation causing the screen cylinder to jam, and indirectly improving the working efficiency of the light material transport mechanism 2. The drive mechanism (especially the transmission shaft and bearing) and the rotating shaft 23 are positioned above the water surface, thereby preventing impurities such as mud and sand from entering the bearing and causing the transmission structure to jam.
[0027] in:
[0028] Reference Figure 4 The scraper assembly 22 includes a connecting plate 222, a connector 223, and a scraper 221. The connector 223 is V-shaped. One end of the connecting plate 222 is fixedly connected to one inclined side of the connector 223, and the other side of the connector 223 is fixedly connected to the scraper 221. The long sides of the connecting plate 222 and the scraper 221 are arranged parallel to the axis of the sieve cylinder. Thus, the connector 223 makes the connecting plate 222 and the scraper 221 form an angle, which can effectively store the scraped material.
[0029] Reference Figure 3 To maximize the collection efficiency of the scraper assembly 22, the connecting plate 222 is a straight plate, angled, and its wide side does not pass through the axis of the screen cylinder. The connecting plate 222 is fixedly connected to the connector 223 of another scraper assembly 22, so that multiple scraper assemblies 22 are connected end-to-end to the arc surface of the closed screen cylinder. Thus, the scraper assembly 22 is angled relative to the horizontal plane, and adjacent scraper assemblies 22 form an angle, moving circumferentially (e.g., ...). Figure 3 When the rotation direction (indicated by arrow c) is reached, the water flow (such as...) is used to scoop up the water. Figure 3 The light material (in the direction indicated by arrow b) accumulates within the angle, ensuring that the material is not easily dropped while being picked up.
[0030] Reference Figure 2To reduce the rotational resistance of the screen cylinder, the connecting plate 222 has multiple water passage holes on its side, which are arranged in an axial array. Thus, when water flows through the screen cylinder, it passes through the water passage holes and passes through the screen cylinder, reducing the resistance of the connecting plate 222 to the water flow, thereby ensuring that the screen cylinder can rotate stably. At the same time, it achieves the effect of draining light materials, reducing the weight conveyed by the screen cylinder, and thus ensuring the stable rotation of the screen cylinder.
[0031] Example 2: Based on Example 1, the following is added:
[0032] Reference Figures 1-3 The circulating water tank 1 has outlets 11 on both sides, and the outlets 11 are located below the screen cylinder.
[0033] To prevent sediment from clogging the outlet 11, a filter barrel 3 is installed inside the circulating water tank 1. The filter barrel 3 is located diagonally below the screen cylinder, and its axis is parallel to that of the screen cylinder. The end face of the filter barrel 3 is crescent-shaped, and its short arc surface is concentric with the screen cylinder. Filter holes are evenly distributed on the short arc surface of the filter barrel 3. Both ends of the filter barrel 3 are connected to the outlet 11. Thus, after the water flows through the screen cylinder, it enters the interior of the filter barrel 3 through the filter holes and is discharged from the outlet 11, thereby preventing sediment from clogging the outlet 11 and indirectly ensuring the stable operation of the screen cylinder. At the same time, it prevents the water level from exceeding the drive mechanism and causing damage to the drive mechanism.
[0034] The scraper 221 is in contact with the short arc surface of the filter barrel 3; thus, when the scraper 221 passes through the short arc surface of the filter barrel, it will scrape off the mud and sand deposited on the filter holes or the debris accumulated on the short arc surface; the screen cylinder rotates, so that multiple scrapers 221 are always in a circumferential movement state, thereby intermittently cleaning the short arc surface and ensuring the stable operation of the filter barrel.
[0035] Example 3: The difference from Example 1 is that the connecting plate 222 is an arc-shaped plate.
[0036] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
