Description
Technical Field
[0001] This application relates to the field of material recycling technology, and in particular to a high-efficiency and energy-saving device for recycling powder and its process. Background Technology
[0002] With increasingly scarce resources and growing environmental awareness, energy conservation and emission reduction have become important directions for sustainable development of enterprises. Recycled powder, as a byproduct of the production process, can be effectively utilized to not only reduce resource waste but also lower production costs and reduce environmental pollution.
[0003] Recycled powder is the aggregate dust collected by the dust removal system of the asphalt concrete mixing plant during the asphalt concrete production process. The use and amount of recycled powder are restricted by the road construction technical specifications. Recycled powder is usually generated in the smoke box. Except for a portion that is used, the excess recycled powder is discarded.
[0004] The existing domestic asphalt concrete mixing plants, as described in relevant technologies, handle recycled powder by directly feeding the aggregate dust collected by the dust removal system into a humidifier, humidifying it, and then discharging it into a pool. The humidified powder is then loaded into trucks and transported away using a forklift. While this method is relatively environmentally friendly, discarding all the recycled powder results in waste, and external discharge increases transportation and processing costs. Therefore, how to recycle and reuse recycled powder is a pressing problem that needs to be solved. Summary of the Invention
[0005] In order to recycle and reuse the recycled powder, and reduce the transportation and processing costs of the recycled powder, this application provides a high-efficiency and energy-saving recycled powder recycling device and process.
[0006] This application provides a high-efficiency and energy-saving device and process for recycling powder, which adopts the following technical solution:
[0007] A high-efficiency and energy-saving recycling powder recycling device includes a material silo, a first storage tank, a second storage tank, a third storage tank, a first conveying mechanism, a second conveying mechanism, a third conveying mechanism, and a first fan;
[0008] The smoke box is connected to the material silo via the first conveying mechanism, the smoke box is connected to the first storage tank via the second conveying mechanism, the smoke box is connected to the second storage tank via the third conveying mechanism, and the first fan is connected to the first storage tank, the second storage tank, and the third storage tank via pipelines respectively;
[0009] The first conveying mechanism, the second conveying mechanism, and the third conveying mechanism can work individually or simultaneously, or any two of them can work simultaneously. The first fan is used to transfer the recycled powder in the second storage tank to the first storage tank or the third storage tank.
[0010] By adopting the above technical solution, during operation, the recycled powder in the smoke box first enters the material silo through the first conveying mechanism, where it can be reused. Secondly, the recycled powder in the smoke box sequentially enters the first and second storage tanks through the second and third conveying mechanisms, thus achieving the recycling and storage of the powder. When the second storage tank is full, the first blower operates, transferring the recycled powder from the second storage tank to the first or third storage tank. This achieves the recycling of the powder. Utilizing the interconnectedness of the first, second, and third storage tanks, the recycled powder continuously circulates, ensuring that both supply and storage needs are met simultaneously. This reduces the costs of transporting and processing the recycled powder, improving the company's economic efficiency.
[0011] Optionally, a second fan is also included, which is connected to the first storage tank, the second storage tank, and the third storage tank via a pipeline. The second fan is used to transfer the recovered powder in the third storage tank to the first storage tank or the second storage tank.
[0012] By adopting the above technical solution, when the third storage tank is full, the second blower can be started to transfer the recovered powder in the third storage tank to the first or second storage tank, thereby realizing the return of the recovered powder and relieving the storage pressure of the third storage tank in a timely manner.
[0013] Optionally, a fourth conveying mechanism is also included, which is installed on the third storage tank and is used to transfer the recycled powder out of the third storage tank.
[0014] By adopting the above technical solution, when the first storage tank, the second storage tank, and the third storage tank are all fully loaded, the recovered powder in the third storage tank can be transferred out by the fourth conveying mechanism.
[0015] Optionally, it also includes a powder extractor and a fifth conveying mechanism, which is installed between the smoke box and the powder extractor, which is used for temporary storage of recycled powder.
[0016] By adopting the above technical solution, and utilizing the powder extraction and fifth conveying mechanism, temporary storage of the recovered powder can be achieved.
[0017] Optionally, a screening mechanism is also included, which is disposed in the material silo and is used to screen the recycled powder entering the material silo.
[0018] By adopting the above technical solution, the screening mechanism screens the recovered powder, improving the quality of the recovered powder and facilitating its reuse.
[0019] Optionally, the screening mechanism includes a drive motor, a housing, and a filter screen. The drive motor is installed on the top of the material hopper, the filter screen is installed on the bottom of the housing, and the drive motor drives the housing to rotate.
[0020] By adopting the above technical solution, the drive motor drives the housing to rotate, and the centrifugal force is used to make the recovered powder fall off the filter screen, thereby realizing the sieving of the recovered powder.
[0021] Optionally, the screening mechanism further includes a rotary motor and a brush plate. The rotary motor is mounted on the filter screen, and the rotary motor drives the brush plate to rotate, with the brush plate contacting the upper surface of the filter screen.
[0022] By adopting the above technical solution, the rotary motor drives the brush plate to rotate, and the brush plate sweeps across the filter plate, further improving the screening effect.
[0023] Optionally, it also includes a control system and a detection system. The detection system is used to detect the amount of recycled powder stored in the material silo, the first storage tank, the second storage tank, and the third storage tank. The control system is used to control the conveying of recycled powder to the material silo, the first storage tank, the second storage tank, and the third storage tank.
[0024] By adopting the above technical solutions, and utilizing control and detection systems, a high degree of automation can be achieved, reducing operational difficulty.
[0025] Optionally, a sixth conveying mechanism is also included, which is installed between the material bin and the first storage tank and is used to transfer the recycled powder from the first storage tank to the material bin.
[0026] By adopting the above technical solution, when the material silo needs to recover powder, the sixth conveying mechanism can quickly transfer the recovered powder in.
[0027] Optionally, a high-efficiency and energy-saving recycling process for the recovered powder includes the following steps:
[0028] The fifth conveying mechanism collects the recycled powder from the cigarette box into the powder extractor.
[0029] The recovered powder from the powder extraction process is transported to the material silo, the first storage tank, and the second storage tank.
[0030] The recovered powder in the second storage tank is blown into the first storage tank or the third storage tank by the first blower;
[0031] The recycled powder in the third storage tank is returned to the first and second storage tanks by the second fan, or it is output by the fourth conveying mechanism.
[0032] By adopting the above technical solution, a fifth conveying mechanism is installed at the smoke box location. The recovered powder is then conveyed to a powder extraction unit, and subsequently fed into a material silo, a first storage tank, and a second storage tank for recycling and storage. When the second storage tank is full, the powder can be transferred using a first blower, achieving the recycling of the recovered powder. This reduces the transportation and processing costs of the recovered powder, improves the company's economic efficiency, realizes the recycling of the recovered powder, reduces resource waste in the production process, and also reduces the processing pressure on construction waste landfills, which is beneficial to environmental protection and sustainable development.
[0033] In summary, this application includes at least one of the following beneficial technical effects:
[0034] 1. This application provides a high-efficiency and energy-saving recycling device for recycled powder. The device uses a powder-collecting screw installed at the smoke box to convey the recycled powder to a powder extractor, which then sends it to a recycling material silo and a storage tank for storage and recycling. When the storage tank is full, a blower can transfer the powder, achieving recycling. This reduces the transportation and processing costs of the recycled powder, improves the economic efficiency of enterprises, realizes the recycling of the powder, reduces resource waste in the production process, and also reduces the processing pressure on construction waste landfills, thus contributing to environmental protection and sustainable development.
[0035] 2. This application includes a material silo, which contains a screening mechanism to screen the recovered powder, thereby improving the quality of the recovered powder and facilitating its reuse.
[0036] 3. This application also includes an atomizing mechanism. Since the recovered powder has a small particle size, it is easy to cause environmental pollution during the transfer process. By using the atomizing mechanism, the recovered powder can be humidified, making the transfer process more environmentally friendly and reducing environmental pollution. Attached Figure Description

[0043] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0044] This application discloses a high-efficiency and energy-saving device for recycling and reusing powder, referring to... Figure 1 and Figure 2 The high-efficiency and energy-saving recycling powder recycling device includes a material bin 2, a first storage tank 3, a second storage tank 4, a third storage tank 5, and a first fan 6. The smoke box 1 can be connected to the material bin 2, the first storage tank 3, the second storage tank 4, and the third storage tank 5 respectively. The first fan 6 is connected to the first storage tank 3, the second storage tank 4, and the third storage tank 5 respectively through pipelines, and the first fan 6 transfers the recycled powder in the second storage tank 4 to the first storage tank 3 or the third storage tank 5.
[0045] During normal operation, the recycled powder in smoke box 1 can enter material silo 2 for subsequent production reuse. When the amount of recycled powder in material silo 2 meets the supply demand, the recycled powder in smoke box 1 enters the first storage tank 3 and the second storage tank 4 for storage. When the second storage tank 4 is full, the first blower 6 operates, transferring the recycled powder in the second storage tank 4 to the first storage tank 3 or the third storage tank 5. By utilizing the interconnected relationship between the first storage tank 3, the second storage tank 4, and the third storage tank 5, the recycled powder is continuously circulated, ensuring that both supply and storage needs are met, reducing the cost of transporting and processing the recycled powder, and improving the company's economic efficiency.
[0046] Specifically, refer to Figure 1 and Figure 2The smoke box 1 is connected to the material bin 2 via the first conveying mechanism 7, the smoke box 1 is connected to the first storage tank 3 via the second conveying mechanism 8, and the smoke box 1 is connected to the second storage tank 4 via the third conveying mechanism 9. By utilizing the first conveying mechanism 7, the second conveying mechanism 8, and the third conveying mechanism 9, the smoke box 1 is connected to the material bin 2, the first storage tank 3, and the second storage tank 4, while ensuring the automatic conveying of the recycled powder.
[0047] Reference Figure 1 and Figure 2 It is understandable that when material silo 2 needs to recover powder, the first storage tank 3 can directly convey the recovered powder into material silo 2 to meet the timely supply of materials. In this embodiment, a sixth conveying mechanism 10 is provided, which is installed between material silo 2 and the first storage tank 3. When material silo 2 needs to recover powder, the sixth conveying mechanism 10 is used to transfer the recovered powder from the first storage tank 3 to material silo 2, realizing the transformation of the recovered powder from a storage state to a reuse state.
[0048] Of course, the recovered powder in the second storage tank 4 can enter the material silo 2 through the first storage tank 3. Specifically, the first blower 6 is started, and only the pipeline between the first blower 6 and the first storage tank 3 is connected. In this way, the recovered powder can enter the first storage tank 3 through the pipeline, and then be transferred to the material silo 2 by the sixth conveying mechanism 10. This shortens the conveying path and makes the structure simpler and more compact.
[0049] The first conveying mechanism 7, the second conveying mechanism 8, and the third conveying mechanism 9 can operate individually, simultaneously, or any two of them can operate simultaneously. This allows for the reuse or storage of the recycled powder according to actual needs. Through appropriate control, the problem of excessive concentration during storage can be avoided while meeting supply demands.
[0050] For ease of detection and control, this embodiment also includes a control system (not shown in the figure) and a detection system (not shown in the figure). The detection system is used to detect the amount of recycled powder stored in material silo 2, first storage tank 3, second storage tank 4, and third storage tank 5. The control system is used to control the conveying of recycled powder to material silo 2, first storage tank 3, second storage tank 4, and third storage tank 5. By utilizing the control system and detection system, a high degree of automation is achieved, enabling intelligent allocation of recycled powder, reducing operational difficulty, and achieving remote control.
[0051] Reference Figure 2 and Figure 3In this embodiment, a second blower 11 is also provided. The second blower 11 is connected to the first storage tank 3, the second storage tank 4, and the third storage tank 5 through pipelines. The second blower 11 is used to transfer the recovered powder in the third storage tank 5 to the first storage tank 3 or the second storage tank 4. When the third storage tank 5 is full, the second blower 11 is started to transfer the recovered powder in the third storage tank 5 to the first storage tank 3 or the second storage tank 4, realizing the return of the recovered powder and timely relieving the storage pressure in the third storage tank 5.
[0052] The third storage tank 5 is also equipped with a fourth conveying mechanism 12, which can transfer the recycled powder in the third storage tank 5 out. Specifically, it can be transferred to a tank truck or directly sent to manufacturers in need for secondary utilization.
[0053] Of course, since the fourth conveying mechanism 12 is used to transport the recycled powder outward, optionally, an atomizing mechanism can be installed on the fourth conveying mechanism 12. The atomizing mechanism can be used to humidify the recycled powder, making the transfer process more environmentally friendly and reducing environmental pollution. The atomizing mechanism can be an atomizing nozzle, a humidifier, a water spray nozzle, etc., which will not be specifically described or limited in this embodiment.
[0054] In this embodiment, refer to Figure 1 and Figure 2 It also includes a powder extractor 13 and a fifth conveying mechanism 14. The fifth conveying mechanism 14 is installed between the smoke box 1 and the powder extractor 13. The powder extractor 13 can temporarily store the recycled powder. Depending on the situation, the recycled powder can be temporarily stored and then, as needed, transported to the material silo 2, the first storage tank 3, and the second storage tank 4 through the first conveying mechanism 7, the second conveying mechanism 8, and the third conveying mechanism 9.
[0055] Reference Figure 3 and Figure 4 In order to improve the quality of the recycled powder and facilitate its direct reuse, a screening mechanism 15 is also provided in this embodiment. The screening mechanism 15 is located in the material bin 2. The recycled powder will first pass through the screening mechanism 15 and then enter the material bin 2.
[0056] Specifically, refer to Figure 4 and Figure 5The screening mechanism 15 includes a drive motor 151, a housing 152, and a filter screen 153. The drive motor 151 is installed on the top of the material bin 2, and the filter screen 153 is installed on the bottom of the housing 152. The drive motor 151 drives the housing 152 to rotate. By using centrifugal force, the recovered powder falls off the filter screen 153, thus achieving the screening of the recovered powder. To facilitate the connection between the drive motor 151 and the housing 152, a bracket 154 is installed on the top of the housing 152, and the bracket 154 is fixedly connected to the output shaft of the drive motor 151.
[0057] Reference Figure 4 and Figure 5 The screening mechanism 15 also includes a rotary motor 155 and a brush plate 156. The rotary motor 155 is mounted on the filter screen 153. The rotary motor 155 drives the brush plate 156 to rotate, and the brush plate 156 contacts the upper surface of the filter screen 153. The rotary motor 155 drives the brush plate 156 to rotate, and the brush plate 156 sweeps across the filter screen, further improving the screening effect.
[0058] Of course, depending on actual needs, corresponding valves (solenoid valves) need to be installed on the pipeline to control the connection or closure of each pipeline. In this embodiment, the valves are not shown, and the installation of the valves will not be described in detail.
[0059] It should be noted that in this embodiment, the first conveying mechanism 7, the second conveying mechanism 8, the third conveying mechanism 9, the fourth conveying mechanism 12, the fifth conveying mechanism 14, and the sixth conveying mechanism 10 all adopt a spiral conveying method. Using a spiral conveying method can achieve a closed conveying effect, reducing the environmental pollution caused by the recovered powder during the conveying process. In this embodiment, the specific structures of the first conveying mechanism 7, the second conveying mechanism 8, the third conveying mechanism 9, the fourth conveying mechanism 12, the fifth conveying mechanism 14, and the sixth conveying mechanism 10 will not be described in detail.
[0060] In this embodiment, both the first fan 6 and the second fan 11 are Roots blowers, which are characterized by high stability, large volume utilization, and the ability to ensure long-term operation. Of course, depending on the actual situation, other types of blowers that meet the requirements can also be used for the first fan 6 and the second fan 11.
[0061] The implementation principle of the high-efficiency and energy-saving recycled powder recycling device in this application embodiment is as follows: A fifth conveying mechanism 14 installed at the smoke box 1 delivers the recycled powder to the powder extractor 13, and then through the first conveying mechanism 7, the second conveying mechanism 8, and the third conveying mechanism 9, respectively, it is fed into the material silo 2, the first storage tank 3, and the second storage tank 4 for recycling and storage. When the second storage tank 4 is full, the recycled powder can be transferred to the first storage tank 3 or the third storage tank 5 by the first fan 6, realizing the recycling of the recycled powder. This reduces the transportation and processing costs of the recycled powder, improves the economic benefits of enterprises, realizes the recycling of the recycled powder, reduces resource waste in the production process, and also reduces the processing pressure on construction waste landfills, which is conducive to environmental protection and sustainable development.
[0062] This application also discloses a high-efficiency and energy-saving recycling process for recycled powder, which includes the following steps:
[0063] The recovered powder in the smoke box 1 is collected into the powder extractor 13 by the fifth conveying mechanism 14;
[0064] The recovered powder in powder extraction 13 is transported to material silo 2, first storage tank 3 and second storage tank 4;
[0065] The recovered powder in the second storage tank 4 is blown by the first blower 6 into the first storage tank 3 or the third storage tank 5;
[0066] The recovered powder in the third storage tank 5 is returned to the first storage tank 3 and the second storage tank 4 by the second fan 11, or it is output by the fourth conveying mechanism 12.
[0067] The implementation principle of the high-efficiency and energy-saving recycling process of this application embodiment is as follows: by utilizing the interconnection between the material silo 2, the first storage tank 3, the second storage tank 4, and the third storage tank 5, the recycling of the recycled powder is realized, reducing resource waste in the production process and also reducing costs.
[0068] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
