Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, and in particular to a high-efficiency feeding device for a vertical pyrolysis furnace. Background Technology

[0002] In industrial production, vertical pyrolysis furnaces are an indispensable material handling device, widely used in mineral processing, chemical production, and many other important fields. However, existing feeding devices have revealed many significant problems during actual operation. These problems severely restrict the improvement of production efficiency and the stability of product quality. Specifically, traditional feeding devices generally lack efficient and reliable filtration and cleaning mechanisms, resulting in materials not being adequately screened and processed before entering the pyrolysis furnace. As a result, materials with uneven particle sizes directly enter the furnace, which not only significantly reduces the efficiency of the pyrolysis process but also has a high probability of causing coking and blockage inside the furnace. Serious malfunctions can affect the normal operation of the entire production line. In addition, after prolonged continuous use, the filter screen is easily clogged by a large amount of material, which seriously affects its filtration effect. Currently, the commonly used cleaning method is manual cleaning, which is not only inefficient and time-consuming, but also poses significant safety hazards. It is difficult to meet the high requirements of modern industrial production for continuous and automated operations. More importantly, most existing cleaning structures use brushes for cleaning, which are difficult to thoroughly unclog deep blockages in practical applications, resulting in unsatisfactory cleaning results and failing to fundamentally solve the problem of filter screen clogging.

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] like Figures 1-5 As shown, this embodiment provides a high-efficiency feeding device for a vertical pyrolysis furnace, including a feeding box 1. The feeding box 1 is equipped with a filter screen 2 with a certain inclination angle. A crushing component 3 is located inside the feeding box 1 and above the filter screen 2, which can crush the material to avoid affecting the production quality. A motor 4 for driving the crushing component 3 is provided on one side of the feeding box 1. An air pump 5 is provided on the feeding box 1. A cleaning component 6 is provided inside the feeding box 1. The cleaning component 6 is located between the filter screen 2 and the crushing component 3. The cleaning component 6 is fixedly connected to the output end of the air pump 5 and can scrape off the residual material on the surface of the filter screen 2 to avoid clogging of the filter screen 2 and affecting the screening and filtration.

[0021] As a technical optimization solution of this utility model, specifically as follows: Figure 4 As shown, the crushing assembly 3 includes a first crushing roller 301 and a second crushing roller 302. The first crushing roller 301 and the second crushing roller 302 are rotatably mounted inside the feed box 1, and the first crushing roller 301 is fixedly connected to the output end of the motor 4. Rotating gears 303 are mounted on the first crushing roller 301 and the second crushing roller 302, and the rotating gears 303 mesh with each other. The output end of the motor 4 drives the first crushing roller 301 to rotate. The first crushing roller 301 drives the second crushing roller 302 to rotate synchronously in the opposite direction through the meshing transmission of the rotating gears 303, forming a high-speed relative rotation between the two rollers. In the moving crushing zone, raw materials such as solid waste and biomass are then fed into the feed port 7 on the upper surface of the feed box 1. The material falls between the first crushing roller 301 and the second crushing roller 302, where it is squeezed and sheared by the two rollers. The crushed material falls downward onto the inclined filter screen 2. Fine particles or materials that meet the particle size requirements pass through the mesh of the filter screen 2 under the action of gravity and fall to the bottom of the feed box 1 or directly enter the next process. Large particles or clumps of material that are not completely crushed roll along the inclined surface of the filter screen 2 and gather at the end of the filter screen 2.

[0022] As a technical optimization solution of this utility model, specifically as follows: Figure 5As shown, the cleaning component 6 includes an electric slide rail 601, which is fixedly installed inside the feed box 1 and parallel to the filter screen 2. An installation plate 602 is connected to the output end of the electric slide rail 601, and a cleaning brush 603 is connected to the installation plate 602. The cleaning brush 603 contacts the filter screen 2. A connecting pipe 604 is provided on the installation plate 602, and a slag blowing head 605 is connected to the connecting pipe 604. An air inlet pipe 606 is provided on the connecting pipe 604, and the other end of the air inlet pipe 606 is fixedly connected to the output end of the air pump 5. The air inlet pipe 606 is made of flexible hose. When the filter screen 2 is affected by material adhesion or fine particles clogging the mesh, thus affecting the screening efficiency, the electric slide rail 601 is activated, causing the installation plate 602 to move along the filter screen. 2. Moving back and forth along the length direction, the cleaning brush 603 on the mounting plate 602 simultaneously scrapes against the surface of the filter screen 2 to remove the attached material. At the same time, the air pump 5 starts, and compressed air enters the connecting pipe 604 through the air inlet pipe 606, and finally blows into the pores of the filter screen 2 through the spray hole of the blower head 605. The airflow impact further clears the blocked mesh holes. The upper surface of the feed box 1 is provided with a feed inlet 7, and a baffle 8 is snapped onto the feed box 1. The baffle 8 is located at one end of the filter screen 2. For the uncrushed material gathered at the lower end of the filter screen 2, the baffle 8 on the feed box 1 can be removed by snapping, and the material can be collected and put back into the feed inlet 7 for secondary crushing to ensure that the material is fully refined to meet the feeding requirements of the pyrolysis furnace.

[0023] In use, the motor 4 is started, and the output of the motor 4 drives the first crushing roller 301 to rotate. The first crushing roller 301 drives the second crushing roller 302 to rotate synchronously in the opposite direction through the meshing transmission of the rotating gear 303. A high-speed relative motion crushing zone is formed between the two rollers. Then, the raw materials to be processed, such as solid waste, biomass, etc., are fed into the feed port 7 on the upper surface of the feed box 1. The material falls between the first crushing roller 301 and the second crushing roller 302 and is squeezed and sheared by the two rollers. The crushed material falls downward onto the inclined filter screen 2. Fine particles or materials that meet the particle size requirements pass through the mesh of the filter screen 2 under the action of gravity and fall to the bottom of the feed box 1 or directly enter the next process. Large particles or clumps of material that are not completely crushed roll along the inclined surface of the filter screen 2 and gather at the end of the filter screen 2. During the crushing and screening process, if the filter screen 2 is clogged by material adhesion or fine particles, affecting the screening efficiency, the cleaning component 6 inside the feed box 1 can be activated, and the electric slide rail 601 can be activated, causing the mounting plate 602 to move back and forth along the length of the filter screen 2. The cleaning brush 603 on the mounting plate 602 simultaneously scrapes against the surface of the filter screen 2 to remove the attached material. At the same time, the air pump 5 is activated, and compressed air enters the connecting pipe 604 through the air inlet pipe 606, and finally blows into the pores of the filter screen 2 through the spray hole of the blower head 605. The airflow impact further clears the clogged mesh. For the uncrushed material gathered at the lower end of the filter screen 2, the baffle 8 on the feed box 1 can be removed by snap-fit, and the material can be collected and put back into the feed inlet 7 for secondary crushing to ensure that the material is sufficiently fined to meet the feeding requirements of the pyrolysis furnace.

Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention.
