Description

TECHNICAL FIELD

[0001] The present application relates to the polishing technical field, especially to a non-metal processing system. BACKGROUND

[0002] The existing waste metal recycling needs to treat the metal surface to remove the dust and rust on the metal surface. The existing technology uses polishing process. The process is determined by the properties of the waste metal raw material and generally needs to be completed by multiple process section devices. In order to ensure efficiency, the multiple process section devices are connected head to tail. Since the devices in each process section have vibration mechanisms, the hot air containing dust generated in the treatment process is easy to escape from the connection part of the devices in each process section and pollute the surrounding environment. Due to the different vibration conditions of the devices in each process section, it is difficult to use a single seal to prevent the escape of the hot air containing dust. SUMMARY

[0003] The present application aims to provide a non-metal processing system with good dust, rust and water removal effect, high efficiency and full utilization of heat energy.

[0004] The present application is achieved by including a closed transversely arranged vibration long channel with vibration devices symmetrically arranged on both sides, a hot air production device, a dust and moisture removal device, and a first dust separation device. The hot air outlet of the hot air production device is connected to the material outlet end of the vibration long channel. The material inlet of the vibration long channel is connected to the material outlet of the dust and moisture removal device. The air guide inlet of the first dust separation device is connected to the air outlet at the rear end of the dust and moisture removal device through an air pipe.

[0005] Preferably, one end of the air guide outlet of the first dust separation device is connected to the atmosphere, and the other end is connected to the air return inlet of the material outlet end of the vibration long channel through an air pipe.

[0006] In operation, the waste metal blocks are introduced from the material inlet of the dust and moisture removing device, flow through the dust and moisture removing device, and then introduced from the material inlet of the vibrating long channel. After polishing and grinding in the vibrating long channel, the waste metal blocks are introduced from the material outlet of the vibrating long channel. The high-temperature hot air of the hot air production device is introduced from the hot air inlet of the vibrating long channel, and then introduced from the material inlet of the vibrating long channel after being introduced from the material outlet of the vibrating long channel. The waste metal blocks are then introduced into the dust and moisture removing device from the material outlet of the dust and moisture removing device. The dust and moisture removing device is then introduced from the air outlet at the rear end of the dust and moisture removing device to the first dust separating device. After the dust in the air is removed by the first dust separating device, part of the dust-free air is discharged to the atmosphere, and part of the dust-free air is returned to the vibrating long channel from the air return inlet at the material outlet end of the vibrating long channel. The technical principle is that after the waste metal blocks enter the vibrating long channel, the power vibrating mechanism acts on the vibrating long channel to make the vibrating long channel vibrate. The waste metal blocks in the vibrating long channel continuously tumble in the process of moving along the material outlet at the other end of the vibrating long channel. In the process of tumbling, the waste metal blocks are polished and ground by mutual friction to remove rust and dust on the waste metal blocks. The introduced hot air carries the polished and ground rust and dust out of the vibrating long channel from another part of the vibrating long channel. The use of high-temperature hot air can significantly improve the polishing and grinding efficiency. The hot air discharged from the vibrating long channel still contains a large amount of heat energy. Therefore, the hot air is introduced into the dust and moisture removing device to dry the waste metal blocks and remove part of the impurities mixed in the waste metal blocks, thereby achieving the effect of pretreating the waste metal blocks and stabilizing the quality of the raw materials entering the vibrating long channel to stabilize the rust removal process of the vibrating long channel. Part of the dust-free air introduced by the first dust separating device is introduced back into the dust and moisture removing device and the vibrating long channel, which can effectively utilize the heat energy of the hot air.

[0007] Preferably, the dust and moisture removing device comprises a long channel and a vibrating mechanism for vibrating the long channel. The front end of the long channel is a material outlet, the rear end of the long channel is provided with a material inlet, and the air outlet is arranged at the rear end of the long channel.

[0008] Preferably, a plurality of first slopes are arranged along the inner cavity of the vibrating long channel, and the first slopes are inclined upward toward the material outlet of the vibrating long channel. The slopes are arranged to prolong the time for the waste metal blocks to stay in the vibrating long channel and to make the waste metal blocks fall from the upper end of the slopes to be directly subjected to the hot air.

[0009] Preferably, a plurality of second slopes are arranged along the inner cavity of the long channel of the dust and moisture removing device, and the second slopes are inclined upward toward the material outlet of the long channel.

[0010] Preferably, an air pressure plate is arranged along the upper cavity wall of the inner cavity of the vibrating long channel and the upper cavity wall of the long channel of the dust and moisture removing device. The air pressure plate is used to press the hot air flowing in the axial direction onto the waste metal blocks below, thereby efficiently utilizing the hot air to heat the waste metal blocks.

[0011] Preferably, the inner cavity of the long channel is equipped with a baffle plate densely covered with sieve holes, dividing the long channel into an upper channel and a lower channel. The lower channel is equipped with a dust outlet and a water outlet. Using the baffle plate with densely covered sieve holes, the waste metal block material moves towards the material outlet during vibration. The dust and water contained in the waste metal block material are promptly filtered into the lower channel and discharged through the dust outlet and water outlet respectively. This reduces the load on the hot air drying and dust removal processes, accelerates the efficiency of the dust removal and dehumidification devices, and significantly reduces the amount of dust and water contained in the hot air. This reduces the load on the first dust separation device and ensures high heat energy and low humidity after hot air treatment, allowing for effective reuse.

[0012] Preferably, a seal is provided between the material outlet of the long channel of the dust removal and dehumidification device and the material inlet of the vibrating long channel to prevent hot air from overflowing, thereby avoiding dust pollution of the environment in the hot air.

[0013] Preferably, the connection between the material outlet of the long channel of the dust removal and dehumidification device and the material inlet of the vibrating long channel is surrounded by a sealed cavity. The sealed cavity is connected to the air inlet of the first dust separation device through a duct. Since the vibration of the dust removal and dehumidification device is asynchronous with the vibration of the vibrating long channel, even with a seal, hot air leakage is unavoidable. The first dust separation device creates a negative pressure in the sealed cavity, sending the leaked hot air to the first dust separation device for treatment, thus preventing hot air from leaking into the environment.

[0014] Preferably, a second dust separation device is provided. The air intake on the material outlet end of the vibrating long channel is connected to the air inlet of the second dust separation device, and the air outlet of the second dust separation device is connected to the return air inlet at the material outlet end of the vibrating long channel. In this way, the hot air carried out with the material at the material outlet end of the vibrating long channel is introduced into the second dust separation device. After dust removal, it flows back into the vibrating long channel, which makes full use of thermal energy and avoids dust pollution of the surrounding environment caused by the hot air carried out by the material.

[0015] Preferably, a central air outlet is provided in the middle of the long channel of the dust removal and dehumidification device, and the central air outlet is connected to the air inlet of the second dust separation device. In this way, the lower temperature hot air discharged from the long channel of the dust removal and dehumidification device is used to reduce the temperature of the hot air discharged from the material outlet, so as to avoid the excessively high temperature from affecting the operation of the second dust separation device. At the same time, the hot air discharged from the long channel of the dust removal and dehumidification device is also used for dust removal.

[0016] Preferably, the vibrating long channel and hot air production device connected together are housed in one of the containers, while the dust removal and dehumidification device and the first dust separation device connected together are housed in another container.

[0017] In use, as needed, the container carrying the technology of this invention is transported to the scrap metal yard. The vibrating tunnel is connected to the dust removal and dehumidification device. The top cover of the container carrying the dust removal and dehumidification device is opened, and the feeding frame is installed. A conveying device is set up between the yard and the feeding frame to transfer the scrap metal blocks from the yard to the feeding frame for processing. When scrap metal blocks from other yards need to be processed, simply remove the feeding frame and conveying device, close the container top cover, separate the vibrating tunnel from the dust removal and dehumidification device, and then transport the scrap metal blocks to the other yard. The feeding hopper includes a funnel-shaped feeding hopper seat. The cyclone separator is placed next to the long channel of the dust removal and dehumidification device, so that the dust removal and dehumidification device and the dust separation device connected together can be placed in another container. If it is necessary to ensure the rust removal effect or the scrap metal block is severely rusted, two or more vibrating long channels connected to the hot air production device can be directly connected together or the material outlet of one adjacent vibrating long channel connected to the hot air production device can be connected to the material inlet of another vibrating long channel connected to the hot air production device through an intermediate transmission mechanism.

[0018] Compared with existing technologies, this invention has the advantages of good dust removal, rust removal and water removal effects, high efficiency, and full utilization of thermal energy. Attached Figure Description
