Description

Technical Field

[0001] This utility model relates to the field of raw material pretreatment, and in particular to a raw material pretreatment device for metal smelting. Background Technology

[0002] Pretreatment of raw materials for metal smelting includes methods such as crushing, sorting, washing and drying to improve subsequent smelting efficiency, reduce pollution or optimize product quality. Among these methods, crushing is used to produce uniform particles, and sorting is usually combined with screening to ensure the uniformity of raw materials for subsequent processing.

[0003] In the raw material and processing equipment for metal smelting, although the crushing of raw materials can crush large pieces of raw materials into granules, some particles are crushed to a smaller size and generate particulate dust. This dust causes the dust to disperse, affecting the processing environment and also resulting in uneven particle size of the processed raw materials.

[0004] Therefore, in response to the above problems, we propose a raw material pretreatment device for metal smelting to crush raw materials and add isolation and dust collection for protection, so as to make the raw material particle size more uniform. Utility Model Content

[0007] Preferably, the raw materials are fed into the crushing box through the feed inlet, where the crushing components crush the raw materials. The crushed raw materials are discharged through the discharge outlet, while the generated dust particles enter the dust collection hood through the isolation net and are connected by pipelines and diverter seats to achieve dust collection, remove smaller dust particles, make the discharged particles more uniform, prevent the dust from spreading in the environment, and improve practicality.

[0008] Preferably, the crushing assembly includes crushing roller one and crushing roller two. The two ends of crushing roller one and crushing roller two are rotatably connected to the inner wall of the crushing box, respectively. Crushing roller two is arranged in a ring array on the outside of crushing roller one. Crushing blades are fixedly installed on the surface of crushing roller one and crushing roller two. When the crushing blades rotate, they can crush the raw materials.

[0009] Preferably, the diverter is equipped with an inlet pipe for connecting to an external vacuum cleaner. The diverter is connected to the interior of the two dust hoods through the pipe, allowing the vacuum cleaner to collect the dust from the dust collection box.

[0010] Preferably, the separator is a metal mesh with a porous structure on its surface, which is used to screen out excessively small raw material particles and dust.

[0011] Preferably, the first transmission assembly includes a driving gear and a driven gear. The driving gear is fixedly connected to the front end of the first crushing roller, the front end of the second crushing roller is fixedly connected to the driven gear, and the driving gear and the driven gear are meshed together.

[0016] 2. This raw material pretreatment device for metal smelting, with the cooperation of multiple crushing rollers and crushing roller one, achieves efficient crushing. The raw material enters through the top feed port and is discharged through the bottom discharge port after crushing, which facilitates the separate collection of dust and processed raw materials and ensures the uniformity of the processed raw material particles.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-5 This utility model provides an embodiment: a raw material pretreatment device for metal smelting, including a crushing box 1, a feed inlet 2 at the top of the crushing box 1, a discharge outlet 3 at the bottom of the crushing box 1, a crushing assembly inside the crushing box 1 for crushing pretreatment of the incoming raw materials, a mounting bracket 4 fixedly installed at the lower end of the crushing box 1, and dust hoods 5 fixedly installed on both sides of the surface of the crushing box 1, with the crushing box 1 and the dust hoods 5 connected by a through groove. An isolation mesh 6 is provided in the through groove. The isolation mesh 6 is a metal mesh with a mesh structure on its surface, the mesh being used to screen out excessively small raw material particles and dust. The mounting bracket 4 has two... The crushing chamber 1 is equipped with a drive motor 7 and a flow divider 8 on each side. The flow divider 8 and the two dust collectors 5 are connected by pipelines. An outer protective cover 9 is fixedly installed on the front end of the crushing chamber 1. The outer protective cover 9 is equipped with a first transmission component, and the output end of the drive motor 7 is equipped with a second transmission component. The raw material is fed into the crushing chamber 1 through the feed inlet 2. The crushing component crushes the raw material. The crushed raw material is discharged from the discharge outlet 3. The generated dust particles enter the dust collector 5 through the isolation net 6 and are connected to the flow divider 8 by pipelines to achieve dust collection, remove smaller dust particles, make the discharged particles more uniform, prevent the dust from spreading in the environment, and improve practicality.

[0025] Please see Figure 2 and Figure 5In this embodiment, the crushing assembly includes a first crushing roller 101 and a second crushing roller 102. The two ends of the first crushing roller 101 and the second crushing roller 102 are rotatably connected to the inner wall of the crushing box 1, respectively. The second crushing roller 102 is arranged in a ring array on the outside of the first crushing roller 101. Crushing blades are fixedly installed on the surface of both the first crushing roller 101 and the second crushing roller 102. When the crushing blades rotate, they can crush the raw materials. Multiple crushing rollers rotate synchronously, which can crush the incoming raw materials.

[0026] Please see Figure 1 and Figure 3 In this embodiment, the diversion seat 8 is equipped with an inlet pipe for connecting to an external vacuum cleaner. The diversion seat 8 is connected to the interior of the two dust hoods 5 through the pipe. The vacuum cleaner can collect the dust in the crushing box 1. The inlet pipe on the diversion seat 8 is connected to the suction port of the external vacuum cleaner. The diversion seat 8 is the connection node of the two dust hoods 5, so that the dust hoods 5 form a suction passage through the pipe. Thus, the negative pressure in the dust hoods 5 can achieve dust removal. The dust enters the dust hoods 5 through the isolation net 6, realizing the collection of dust particles.

[0027] Please see Figure 1 , Figure 2 and Figure 4 In this embodiment, the first transmission component includes a driving gear 91 and a driven gear 92. The driving gear 91 is fixedly connected to the front end of the first crushing roller 101, and the front end of the second crushing roller 102 is fixedly connected to the driven gear 92. The driving gear 91 and the driven gear 92 are meshed together. When the driving gear 91 rotates, it can synchronously drive multiple driven gears 92 to rotate. The second transmission component includes a first transmission wheel 71 and a second transmission wheel 72. The output end of the drive motor 7 is fixedly connected to the first transmission wheel 71. The first transmission wheel 71 and the second transmission wheel 72 are connected by a belt drive to transmit the power of the drive motor 7. The second transmission wheel 72 is connected to the front end of the driving gear 91 by a connector. When the second transmission wheel 72 rotates, it can synchronously drive the driving gear 91 to rotate. The drive motor 7 can drive the first transmission wheel 71 to rotate, so that the second transmission wheel 72 synchronously drives the driving gear 91 to rotate, realizing the transmission of power. The meshing of the driving gear 91 and the driven gear 92 realizes the synchronous transmission of power, driving multiple crushing rollers to rotate synchronously, thereby crushing the raw materials.

[0028] During operation, the equipment is connected to an external power source to power the drive motor 7. The drive motor 7 drives the transmission wheel 71 to rotate, and through transmission wheel 72, it drives the drive gear 91 to rotate, so that multiple driven gears 92 transmit power synchronously. The crushing roller 101 and the crushing roller 202 rotate synchronously. Then, the raw material is fed into the crushing box 1 through the feed port 2. After the raw material enters the crushing box 1, the crushing roller 101 and the crushing roller 202 rotate synchronously to crush the metal raw material. The crushed granules are discharged through the bottom discharge port 3 for easy collection. During the crushing process, the diverter seat 8 is connected to the external dust collection equipment through the access pipe to form a dust collection channel. The dust hood 5 has negative pressure suction to suck the crushed material in the crushing box 1, which facilitates the collection of dust particles. The isolation net 6 is located between the crushing box 1 and the dust hood 5 to form an isolation, preventing large particles from entering the dust hood 5, thereby separating the dust and granules, preventing dust diffusion, and ensuring the uniformity of the granules.

[0029] Through the above steps, the raw material is fed into the crushing box 1 through the feed inlet 2, and the crushing component crushes the raw material. The crushed raw material is discharged through the discharge outlet 3, and the generated dust particles enter the dust collection hood 5 through the isolation net 6. The dust is then connected by the pipeline and the diverter seat 8 to achieve dust collection, remove smaller dust particles, and make the discharged particles more uniform. This also prevents the dust from spreading in the environment and improves practicality. This solves the problem that existing raw material pretreatment devices for metal smelting are prone to dust dispersion and have relatively uneven raw material particle size.
