Description

Technical Field

[0001] The present invention relates to the technical field of polishing, in particular to a polishing machine. Background Art

[0002] For the existing waste metal recycling, determined by the source of the waste metal, the water content, impurity content, and rust situation are complex. Therefore, it is necessary to pre-clean the water and dust on the waste metal block to reduce the burden of subsequent dust removal and rust removal, and at the same time improve the final treatment effect. Patent CN2022218572700 discloses such a technology. Using a vibrating long channel, the waste metal is introduced from one end of the vibrating long channel, led out from the other end of the vibrating long channel, and high-temperature hot air is introduced. The vibrating long channel vibrates, so that the waste metal blocks in the long channel continuously roll during the movement along the discharge at the other end of the long channel, and rub against each other during the rolling process, polishing and grinding the rust and dust on the waste metal blocks, and at the same time evaporating the water. The introduced hot air takes out the polished rust, dust and steam from another place of the long channel. Although this technology can effectively remove the dust, rust and water contained in the waste metal, since it is completed in the same vibrating long channel, if the dust and water content are small and the amount of these impurities contained is stable, there is no problem. The actual situation is that the waste metal is determined by the complexity of the source, and the amount of these impurities such as dust and water contained varies greatly, which not only easily affects the treatment effect, but also the heat energy after treatment cannot be fully utilized. Summary of the Invention

[0003] The purpose of the present invention is to provide a dust removal and dehumidification device that can pre-treat the waste metal block raw materials, ensure the stable quality of the waste metal raw materials even if the waste metal is affected by the complexity of the source, and has a simple structure, low treatment cost and high efficiency.

[0004] The present invention is realized as follows. It includes a horizontally arranged long channel and a vibration mechanism that drives the long channel to vibrate. The front end of the long channel is a material guiding outlet connected to the material inlet of the vibrating long channel for dust removal and rust removal. A material guiding inlet is arranged above the rear end of the long channel, and an air outlet is arranged at the rear end of the long channel. A partition plate with dense sieve holes is arranged in the inner cavity of the long channel, dividing the long channel into an upper channel and a lower channel. A dust guiding outlet and a water guiding outlet are arranged on the lower channel.

[0005] In use, the material inlet of the material for the vibrating long channel for dust removal and rust removal (such as the technology disclosed in Patent CN2022218572700) is connected to the material outlet of the long channel of the present invention. The air guide inlet of the dust separation device is connected to the air outlet at the rear end of the long channel of the present invention through an air duct. Scrap metal blocks are introduced from the material inlet of the long channel, flow through the upper channel of the long channel, enter the vibrating long channel, are polished after passing through the vibrating long channel, and are exported from the discharge port of the vibrating long channel. The high-temperature hot air from the hot air production device is introduced from the air inlet of the vibrating long channel, is exported from the feed port of the vibrating long channel, then is introduced from the material outlet of the long channel, and then is exported from the air outlet at the rear end of the long channel to the dust separation device. The dust separation device removes the dust in the air. Scrap metal blocks are introduced from the material inlet of the long channel. When flowing through the upper channel of the long channel, under the action of the vibrating mechanism, they move towards the material outlet. During the movement, the water and dust contained in the scrap metal blocks pass through the sieve holes of the partition plate and fall into the lower channel and flow out from the dust outlet and the water outlet.

[0006] By adopting a vibrating mechanism, the scrap metal blocks passing through the long channel are thrown up, which is beneficial to the action of hot air, so as to accelerate air drying and the falling of the adhered dust. At the same time, while the scrap metal blocks are being thrown and moving towards the material outlet, the solid dust also moves towards the material outlet direction and flows out from the dust outlet at the front part of the lower channel. The fluid water flows out from the water outlet at the rear part of the lower channel under the action of gravity.

[0007] Since in the long channel, during the drying process, the dust and water adhered to the scrap metal blocks are removed, effectively reducing the dust content in the hot air after treatment. Thus, the dust removal load of the dust separation device is effectively reduced, the cleanliness of the hot air after dust removal is improved, the full utilization of heat energy is enhanced, and at the same time, the load of the hot air for removing dust and water is also reduced.

[0008] After being processed by the technology of the present invention, the scrap metal raw materials with large quality differences become scrap metal blocks with relatively stable quality, so that the subsequent vibrating long channel for dust removal and rust removal can use a stable production process to remove the remaining dust and rust on the scrap metal blocks.

[0009] Preferably, the partition plate is formed by several sub-partition plates connected in series front and back. There are vertically arranged disturbing pieces that can move in the gap between adjacent sub-partition plates, and the disturbing pieces are provided with a support structure supported in the gap. During operation, under the vibration of the vibrating mechanism, the disturbing pieces also vibrate, enabling the dust and water contained in the scrap metal blocks to pass through the gaps on both sides of the disturbing pieces and fall into the lower channel. In this way, even if the sieve holes are blocked by dust during use and the filtering ability of the sieve holes decreases, since the disturbing pieces move in the gap during vibration, the gaps on both sides of the disturbing pieces are not easily blocked during vibration, thus compensating for the insufficient filtering ability of the partition plate caused by partial blockage of the sieve holes.

[0010] Preferably, several slopes are provided along the inner cavity of the upper channel of the long channel. The slopes are provided to prolong the time for the scrap metal to stay in the long channel and to fully affect the hot air when the scrap metal falls from the upper end of the slopes.

[0011] Preferably, an air pressure plate is provided on the upper cavity wall of the upper channel inner cavity of the long channel. The hot air is guided by the air pressure plate, and the air blown in the axial direction is pressed down onto the scrap metal blocks below, so that the hot air is fully utilized and the use efficiency of the hot air is significantly improved.

[0012] Preferably, the long channel is inclined upward toward the material outlet.

[0013] Preferably, the dust outlet is located in the lower channel close to the material outlet, and the water outlet is located in the lower channel close to the material inlet.

[0014] Preferably, the vibration direction of the vibration mechanism is a front-to-back oblique upward vibration direction. The vibration direction of the vibration mechanism adopts a front-to-back vibration direction, so that the scrap metal block can move forward during the vibration, and cooperate with the long channel obliquely upward in the direction of the material outlet, which not only ensures that the scrap metal block moves in the direction of the material outlet, but also prevents the separated dust from moving synchronously with the scrap metal block in the direction of the material outlet, so that the dust can fall into the lower channel in time, and the dust falling into the lower channel can also move upward to the dust outlet at the high position of the lower channel, so as to be discharged separately from the separated water.

[0015] Preferably, a feed hopper is provided on the material inlet at the rear end of the long channel, and the feed hopper includes a funnel-shaped feed hopper seat and a cube-like feed frame arranged on the feed hopper seat. The feed guide port at the bottom of the feed frame is embedded in the connecting sleeve at the upper end of the funnel-shaped feed hopper seat, and the side of the feed frame is a feeding port.

[0016] Preferably, the long channel is inclined upward toward the material outlet, so that water and dust contained in the scrap metal block will not be guided along the long channel to the material outlet to enter the next process, and the water and dust dropped from the scrap metal block will fall into the dust collection bin.

[0017] Preferably, the feeding port is provided with a door curtain.

[0018] Preferably, the facility including the horizontally placed long channel and the vibration mechanism for driving the long channel to vibrate is arranged in a container.

[0019] In use, according to needs, transport the container loaded with the technology of the present invention to the scrap metal yard. Dock the vibrating long channel with the material outlet of the long channel of the technology of the present invention. Open the container top cover, install the feeding frame, and set up a conveying device between the yard and the feeding frame. Then, scrap metal can be transported from the yard into the feeding frame to start processing the scrap metal. When it is necessary to process the scrap metal in other yards, only need to remove the feeding frame and the conveying device, cover the container top cover, separate the vibrating long channel from the invention technology, and then it can be transported to other yards; the feeding hopper includes a funnel-shaped feeding hopper seat. Set the cyclone separator beside the long channel so that the technology of the present invention and the dust separation device connected together can be arranged in another container; if it is necessary to ensure the rust removal effect or the scrap metal is severely rusted, two or more vibrating long channels connected with a hot air production device can be directly connected in series or the material outlet of one of the vibrating long channels connected with a hot air production device adjacent to another vibrating long channel connected with a hot air production device can be communicated with the material inlet through an intermediate transmission mechanism.

[0020] Preferably, a cyclone separator of a dust separation device is arranged beside the long channel.

[0021] Compared with the prior art, the present invention has the advantages that it can pre-process the raw material of scrap metal blocks. Even if the source of the scrap metal is complex, the quality of the scrap metal raw material can be ensured to be stable after processing. Moreover, it has the advantages of simple structure, low processing cost and high efficiency. Description of the Drawings

A material inlet 102 is arranged on the upper part of the rear end of the long channel 1, and an air outlet 103 is arranged at the rear end of the long channel 1. A partition 3 with sieve holes densely distributed is arranged in the inner cavity of the long channel 1, dividing the long channel 1 into an upper channel 104 and a lower channel 105. A dust outlet 106 and a water outlet 107 are arranged on the lower channel 105.

[0029] As Figure 1 、 2 shown, preferably, the partition 3 is composed of several sub - partitions 301 connected in series front and back. Flanges 302 are arranged on the front and rear edges of the sub - partitions 301. A vertically arranged disturbing piece 304 is arranged in the gap 303 between the flanges 302 of adjacent sub - partitions 301, and a support structure 305 that supports in the gap 303 is arranged on the disturbing piece 304.

[0030] As Figure 3 shown, the support structure 305 is a support cross - plate arranged at both ends of the disturbing piece 304. The support cross - plate as the support structure 305 leans against the sub - partitions 301 on both sides of the gap 303.

[0031] Preferably, along the direction of the material outlet 101, the front end of the adjacent rear sub-partition plate 301 is slightly higher than the rear end of the front sub-partition plate 301. In this way, when the scrap metal block C moves forward, the dust and water following the scrap metal block C are blocked by the front end of the rear sub-partition plate 301 and fall into the lower channel 105 from the gap 303.

[0032] Preferably, several slopes 4 are arranged in the inner cavity of the upper channel 104 of the long channel. The slopes 4 slope obliquely upward towards the top surface of the inner cavity of the long channel 1. The inclination angle of the slopes 4 is adjustable, so that the inclination angle of the slopes 4 can be correspondingly adjusted according to the properties of the raw material scrap metal block C, in order to control the dehydration and drying time.

[0033] Preferably, a wind pressing plate 5 is arranged on the upper cavity wall of the inner cavity of the upper channel 104 of the long channel 1. The wind pressing plate 5 slopes obliquely downward towards the bottom surface of the inner cavity of the long channel 1 at an inclination angle of 25-35 degrees.

With the obliquely downward material outlet 101 and the material inlet 9 of the vibrating long channel A that slopes upward, when the scrap metal block C enters the material inlet 9 of the vibrating long channel A from the material outlet 101, it is introduced into the vibrating long channel A in the form of a waterfall, and the gap between the scrap metal blocks expands. Combined with the hot air blowing obliquely downward under the action of the wind pressing plate in the vibrating long channel A, the scrap metal blocks can be fully affected by the hot air.

[0038] Preferably, a middle air outlet 108 is arranged in the middle of the long channel 1.

In this way, the hot air with a lower temperature led out from the long channel is used to reduce the temperature of the hot air led out from the material outlet end of the vibrating long channel A, avoiding the influence of too high temperature on the operation of the dust separation device. At the same time, the hot air led out from the long channel of the dust removal and dehumidification device is dust-removed.
