DETAILED DESCRIPTION

[0020] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0021] Please refer to Figs. 1-3 The present application provides a technical scheme: a gabbro sawing powder activation and drying device, comprising:

[0022] The spiral drying box 1 is internally provided with a spiral structure for spiral conveying and heating drying of the gabbro sawing powder, and the inner wall of the spiral conveying copper pipe 2 is relatively smooth, and the friction coefficient with the gabbro sawing powder is small. Compared with other rough conveying pipelines, it can reduce the abrasion of the gabbro sawing powder in the conveying process. Especially for some gabbro sawing powder that has been preliminarily processed and has relatively small particles, such as gabbro sawing powder tailings, avoiding excessive abrasion can prevent the powder particles from being further refined or generating excessive dust, thereby improving the product quality and reducing the pollution of dust to the environment and equipment. When the spiral conveying copper pipe 2 is heated by the circular heating plate 4, heat can be transferred to the gabbro sawing powder through the pipe wall. At this time, the spiral conveying copper pipe 2 is not only a conveying tool, but also a part of the drying process. In this way, the gabbro sawing powder can be heated before entering the main drying equipment, better connecting with the subsequent drying process, making the drying more uniform and efficient. The feeding end of the spiral conveying copper pipe 2 is connected with a pressure pump 3 arranged in the spiral drying box 1 for pressurized rapid conveying. The pressure pump 3 can accelerate the feeding speed of the gabbro sawing powder, and at the same time, a large amount of gabbro sawing powder can be conveyed into the drying equipment in a short time, improving the production efficiency of the entire drying system. The spiral conveying copper pipe 2 is externally provided with a circular heating plate 4 in a cylindrical structure, which can heat and dry the gabbro sawing powder in the conveying process, reducing the use cost of the drying tower equipment.

[0023] The lower box 5 is connected with the feeding end of the spiral conveying copper pipe 2 at the bottom in a penetrating manner, so that the preliminarily dried gabbro sawing powder enters the internal pressurized spiral conveying of the spiral conveying copper pipe 2. The lower end of the lower box 5 is provided with a pressure pipe 6 connected with the pressure pump 3 for increasing the pressure of the lower box 5, accelerating the speed of the gabbro sawing powder, and reducing the adhesion of the gabbro sawing powder with large moisture to the inner wall. One side of the pressure pipe 6 is provided with an air inlet fan 7 for blowing and drying the gabbro sawing powder in the lower box 5.

[0024] The feed end of the spiral conveying copper pipe 2 passes through the bottom of the spiral drying box 1 and the discharge box 5, allowing the pre-dried sawdust powder to enter the spiral conveying copper pipe 2. A discharge pressure pipe 8 is connected to the feed inlet of the spiral conveying copper pipe 2, which can pressurize the inside of the spiral conveying copper pipe 2 to cause the sawdust powder to move in a spiral motion for heating and drying. Simultaneously, the inner diameter and spiral length of the spiral conveying copper pipe 2 can be increased according to the actual feed flow rate and drying quality to ensure that the sawdust powder is completely dry after exiting the spiral conveying copper pipe 2. The connection port of the pressure pump 3 is connected to the discharge pressure pipe 8. The two ends are connected, and one end of the pressurizing pipe 6 on the feeding box 5 is connected to the feeding pressurizing pipe 8 so that the pressurizing pump 3 can simultaneously pressurize the feeding box 5 and the spiral conveying copper pipe 2. The bottom of the feeding box 5 is provided with a feeding port 15 with a horn structure. The feeding port 15 is connected to the feeding end of the spiral conveying copper pipe 2. The upper end face of the feeding box 5 is provided with a feeding pipe 9 with a material valve. The feeding box 5 is provided with inclined moving feeding plates 10 that keep the sawdust powder moving in a state of motion. The sawdust powder moves and collides during the feeding process to air dry the moisture and avoid clumping.

[0025] The feeding box 5 has a sealing cover on one side of the air inlet cover 11 connected to the air inlet fan 7, so that the heated air is concentrated and enters the feeding box 5. The air inlet cover 11 has a filter 12 on one side, and the air duct connecting the filter 12 and the air inlet cover 11 has a gas heater 13, which can filter the external air and send it to the gas heater 13 for heating. The output end of the spiral conveying copper pipe 2 inside the spiral drying box 1 extends through to the outside of one side of the spiral drying box 1, and the bottom of the spiral drying box 1 has a mounting base 14, so that the drying equipment can operate in a stable state to dry the sawdust powder.

[0026] Specifically, in use, first connect the feeding pipe 9 to the external material pump, allowing the sawdust containing moisture to enter the feeding hopper 5. At this time, the air intake fan 7 and the pressure pump 3 are started. The air intake fan 7 draws in external air into the filter 12 for impurity filtration, and the filtered gas enters the gas heater 13 for heating to remove moisture and keep the gas dry. The heated gas enters the air intake hood 11 and is blown by the air intake fan 7 onto the inclined sawdust moving at an angle on the inclined feeding plate 10. Under the state of inclined and intersecting movement and collision, the moisture in the sawdust gradually decreases, thus preventing the sawdust containing moisture from clumping during feeding and causing pipeline problems. When blockage occurs and material cannot be discharged, the pressure pump 3 pressurizes the spiral conveying copper pipe 2 using the discharge pressure pipe 8. The sawdust powder entering the spiral conveying copper pipe 2 is propelled by the thrust generated by the pressure, causing the sawdust powder to move in a spiral conveying motion within the spiral conveying copper pipe 2. At the same time, the circular heating plate 4 with its cylindrical structure generates high-temperature gas to rapidly heat the spiral conveying copper pipe 2. Because the spiral conveying copper pipe 2 is made of structural material, it heats up quickly and uses pressure to rapidly transport the sawdust powder, ensuring that the sawdust powder in the spiral conveying process is always in motion and undergoes heating and drying. This allows the sawdust powder to be heated and dried evenly during its movement.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
