Description

Technical Field

[0001] This utility model relates to the field of solid waste resource utilization technology, specifically a negative pressure powder feeding and solidification device for solid waste resource utilization. Background Technology

[0002] Solid waste resource utilization, also known as comprehensive utilization of solid waste or solid waste resource recovery, refers to the process of extracting useful substances from solid waste through certain treatment or processing methods, so that they can continue to play a role in industrial and agricultural production, or transform solid waste into new energy or resources. The aim is to accelerate the recycling of materials and energy, create economic value, reduce environmental pollution, and promote sustainable development.

[0003] In existing solid waste resource recovery processes, most traditional open or mechanical conveying methods are used. While these methods meet basic material transport needs to some extent, they have limitations. First, due to the lack of effective sealing and power optimization mechanisms during transport, materials are easily affected by external interference, leading to unstable conveying speeds and frequent material blockages and spillage. This not only increases the difficulty of subsequent processing but also directly reduces the overall efficiency of the production line. Second, in open or mechanical conveying processes, the lack of material control means allows powdery materials to easily become airborne and scattered due to wind and mechanical vibrations. Dust during solid waste treatment not only severely impacts the production environment but also harms employees' respiratory systems and skin. Furthermore, the scattered dust can be carried by the wind to surrounding areas, causing secondary pollution to the natural environment. Because traditional conveying methods cannot effectively control dust dispersion, the risk of dust accumulation and explosion increases. Suspended dust in the air easily forms flammable mixtures, which can trigger explosions when exposed to ignition sources or high-temperature environments.

[0004] Therefore, in order to solve the above problems, a negative pressure powder feeding and solidification device for the resource utilization of solid waste urgently needs to be developed. Summary of the Invention

[0005] The purpose of this invention is to provide a negative pressure powder feeding and solidification device for solid waste resource utilization, which has the advantages of safety and high efficiency, and solves the problems mentioned in the background technology.

Both driven gears mesh with the drive gear. A spiral stirring rod and a high-efficiency stirring rod are fixedly connected to the bottom of the drive gear and driven gear, respectively. A storage tank is fixedly connected to the other side of the top of the curing reactor. A conveying pipe is connected to the bottom of one side of the storage tank. One end of the conveying pipe is connected to the curing reactor.

[0008] A powder suction pipe is connected to one side of the second pulley.

[0009] Furthermore, as a preferred embodiment of this utility model, a support block is fixedly connected to the surface of the connecting pipe, and the bottom of the support block is fixedly connected to the workbench.

[0010] Furthermore, as a preferred embodiment of this utility model, a support frame is fixedly connected to the surface of the transmission tube, both ends of the support frame are fixedly connected to the workbench, and one side of the support frame is fixedly connected to the filter.

[0011] Furthermore, as a preferred embodiment of this invention, a fixed gear ring is fixedly connected to the top of the inner cavity of the curing reactor, and both driven gears mesh with the fixed gear ring.

[0012] Furthermore, as a preferred embodiment of this invention, a support ring is fixedly connected to the surface of the curing reactor, and four support rods arranged in a ring are fixedly connected to the bottom of the support ring.

[0013] Furthermore, as a preferred embodiment of this invention, a flow control valve is connected to the surface of the conveying pipe.

[0014] Beneficial Effects: The technical solution of this application has the following advantages: This utility model has the advantages of safety and efficiency. In actual use, the negative pressure generated by the vacuum pump is used to efficiently and stably transport the powder to the curing reactor through a closed pipeline. This conveying method not only improves the conveying efficiency of the powder, but also reduces the loss and waste of materials during the conveying process. At the same time, since the conveying process is carried out in a closed environment, the leakage and dispersion of dust are avoided, effectively preventing dust pollution to the environment. Compared with the traditional open conveying method, negative pressure conveying can significantly reduce the dust concentration, protect the production environment and the health of employees, and reduce the risk of dust accumulation and explosion due to the negative pressure state in the conveying pipeline. In addition, the set stirring rod can fully and evenly mix the curing agent and the powder, promote the rapid progress of the curing reaction, not only improve the product quality and stability, but also shorten the production cycle and further improve the overall production efficiency.

The bottom of the driving gear 66 and the driven gears 68 are respectively fixedly connected to a spiral stirring rod 69 and a high-efficiency stirring rod 610. A storage tank 611 is fixedly connected to the other side of the top of the curing reactor 61. A conveying pipe 612 is connected to the bottom of one side of the storage tank 611. One end of the conveying pipe 612 is connected to the curing reactor 61.

[0024] One side of pulley 264 is connected to a powder suction pipe 7.

[0025] Specifically, a support block 8 is fixedly connected to the surface of the connecting pipe 3, and the bottom of the support block 8 is fixedly connected to the workbench 1.

[0026] In this embodiment, the support block 8 serves to support the connecting pipe 3, ensuring the stability of the connecting pipe 3.

[0027] Specifically, a support frame 9 is fixedly connected to the surface of the transmission pipe 5. Both ends of the support frame 9 are fixedly connected to the workbench 1, and one side of the support frame 9 is fixedly connected to the filter 4.

[0028] In this embodiment, the support frame 9 serves to support and fix the transmission pipe 5 and the filter 4, ensuring the stability of the transmission pipe 5 and the filter 4.

[0029] Specifically, a fixed gear ring 613 is fixedly connected to the top of the inner cavity of the curing reactor 61, and two driven gears 68 mesh with the fixed gear ring 613.

[0030] In this embodiment, the fixed gear ring 613 provides further support for the two driven gears 68, ensuring the stability of the two driven gears 68 during rotation.

[0035] The working principle and usage process of this utility model are as follows: The user turns on the vacuum pump 2 to generate negative pressure, making the pressure inside the connecting pipe 3, transmission pipe 5, curing structure 6, and powder suction pipe 7 lower than the external atmospheric pressure, creating a negative pressure environment. Under this negative pressure, the powder is transported to the inner cavity of the curing reactor 61 by the airflow generated by the vacuum pump 2 through the powder suction pipe 7. If other powder is being discharged through the transmission pipe 5, it is filtered by the filter 4 when it reaches the filter, preventing the powder from being discharged into the external air again. After the weighing sensor 616 determines the amount of powder to be cured in the inner cavity of the curing reactor 61, the vacuum pump 2 is turned off. Then, an appropriate amount of curing agent is delivered into the inner cavity of the curing reactor 61 by opening the transmission pipe 612. Motor 62's output shaft drives pulley 63 to rotate. Pulley 63 drives transmission rod 65 to rotate via pulley 64. Transmission rod 65 drives spiral stirring rod 69 to rotate via drive gear 66. Simultaneously, since drive gear 66 meshes with two driven gears 68, drive gear 66 drives driven gears 68 to rotate. Driven gears 68 drive high-efficiency stirring rod 610 to rotate. The rotation of high-efficiency stirring rod 610 and spiral stirring rod 69 mixes and stirs the powder and curing agent in the inner cavity of curing reactor 61, thereby completing the curing process of the powder. After the process is completed, motor 62 is turned off, and the output port of curing reactor 61 is opened to discharge the cured powder.
