Description

Technical Field

[0001] This utility model belongs to the technical field of lead concentrate processing equipment, specifically relating to a double spiral classifier for lead concentrate processing. Background Technology

[0002] In the processing of lead concentrate, the grading operation is a crucial step, directly affecting the quality and efficiency of subsequent processing. With the rapid development of modern industry, the market has placed more stringent requirements on the purity, particle size distribution, and other quality indicators of lead products. At the same time, the demand for large-scale, high-efficiency lead concentrate processing has also prompted the industry to continuously optimize production processes and equipment.

[0003] A patent search revealed a Chinese patent, CN215823333U, for a double-spiral classifier for lead concentrate processing and grading. This patent includes a main body, a controller, and a power cord. By incorporating a recycling component within the main body, a drainage channel, and a sump, it facilitates the recycling and utilization of overflow water, saving water resources and reducing energy consumption. The cooperation between the water pump and the inner frame allows overflow water to clean the lower side of the sump, preventing material residue at the bottom and eliminating the need for secondary cleaning, thus saving water. An adjustment component at the lower end of the drainage channel, along with an output belt, moves the filter plate outwards, facilitating cleaning of the filter plate surface, saving time, and improving cleaning efficiency. An intermittent component at the upper part of the main body allows the transmission rollers to intermittently and uniformly transport material downwards, preventing large amounts of material from falling downwards at once and improving grading efficiency.

[0004] Problems with existing technology:

[0005] The grooves on the aforementioned transmission rollers make it difficult to flexibly adjust their volume and feed rate according to the characteristics of different lead concentrates and the varying classification requirements. This results in poor classification accuracy, inconsistent product quality, and can also affect the uniformity of material feeding, causing material blockage inside the equipment and reducing production efficiency. Utility Model Content

[0006] The purpose of this invention is to provide a double spiral classifier for lead concentrate processing, which can flexibly adjust the volume of the feeding trough, achieve precise control of the feeding process, and significantly improve the classification efficiency.

[0007] The specific technical solution adopted by this utility model is as follows:

[0008] A double-spiral classifier for lead concentrate processing includes a main body. The main body has an internal collecting trough with two inner walls provided with feeding ramps. A feeding roller is located inside the collecting trough and between the feeding ramps. A feeding pipe is provided through the top of the main body. Multiple feeding troughs are arranged circumferentially on the outer wall of the feeding roller. An adjusting plate for adjusting the volume of the feeding trough is provided inside the feeding trough. Multiple telescopic airbags connected to the adjusting plate are provided on the inner wall of the feeding trough. An air passage is provided inside the feeding roller, and a connection port communicating with the telescopic airbags is provided inside the air passage.

[0009] An air pump is provided on one side of the main body, and an air pipe is connected to the air port of the air pump. The air pipe is rotatably and sealed to the air passage through a connector.

[0010] The telescopic airbag is equipped with a spring inside for automatic resetting of the telescopic airbag.

[0011] A rotating shaft is rotatably installed inside the material collection trough and directly above the feeding roller. The outer wall of the rotating shaft is provided with bidirectional spiral blades for spreading the raw material to both sides of the feeding roller.

[0012] A motor is provided on one side of the main body, and the output shaft of the motor is connected to the feed roller. One end of the rotating shaft extends to the outside of the main body and is provided with a belt connected to the motor, which is used to drive the rotating shaft and the feed roller to rotate through the motor.

[0013] The technical effects achieved by this utility model are as follows:

[0014] This invention utilizes the synergistic effect of an air pump, a telescopic airbag, and an adjusting plate to flexibly adjust the volume of the feeding trough according to the characteristics and grading requirements of different lead concentrates, achieving precise control over the feeding process and significantly improving the grading effect. The design of the rotating shaft and bidirectional spiral blades can spread the concentrated lead concentrate to both sides, allowing the raw materials to enter the feeding trough evenly, further improving the uniformity of feeding and working efficiency, and also optimizing the grading effect.

[0021] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0022] like Figures 1-4 As shown, a double spiral classifier for lead concentrate processing includes a main body 1. A collection trough 2 is provided inside the main body 1. Both inner walls of the collection trough 2 are provided with discharge ramps 3. A discharge roller 4 is provided inside the collection trough 2 and between the discharge ramps 3. A feeding pipe 18 is provided through the top of the main body 1. Multiple feeding troughs 5 are arranged circumferentially on the outer wall of the discharge roller 4. An adjusting plate 6 for adjusting the volume of the feeding trough 5 is provided inside the feeding trough 5. Multiple telescopic airbags 7 connected to the adjusting plate 6 are provided on the inner wall of the feeding trough 5. An air passage 10 is provided inside the discharge roller 4. A connection port 9 communicating with the telescopic airbags 7 is provided inside the air passage 10. An air pump 11 is provided on one side of the main body 1. An air pipe 12 is connected to the air port of the air pump 11. The air pipe 12 is rotatably connected to the air passage 10 via a connector 13. A spring 8 for automatic reset of the telescopic airbag 7 is provided inside the telescopic airbag 7.

[0023] According to the above structure, before feeding, the air pump 11 is started. The air pump 11 inflates the telescopic airbag 7 through the air pipe 12, and together with the air passage 10 and the connection port 9, so that the air pump 11 collidees and pushes the adjusting plate 6 to move in the feeding trough 5, so as to realize flexible adjustment of the feeding process and improve the grading effect. The spring 8 is set so that when the telescopic airbag 7 deflates and contracts, the spring force of the spring 8 can make the telescopic airbag 7 retract smoothly, thereby driving the adjusting plate 6 to move smoothly down, improving the practicality of the equipment.

[0024] like Figures 2-3 As shown, a rotating shaft 14 is rotatably installed inside the collecting trough 2 and directly above the feeding roller 4. The outer wall of the rotating shaft 14 is provided with bidirectional spiral blades 15, which are used to spread the raw material to both sides of the feeding roller 4.

[0025] Based on the above structure, the combination of the rotating shaft 14 and the bidirectional spiral blade 15 causes the rotating shaft 14 to rotate, which in turn drives the bidirectional spiral blade 15 to rotate, pushing the raw material concentrated in the middle of the collecting trough 2 to both sides and flattening it, so that the raw material can be filled into the feeding trough 5, improving the uniformity of feeding and further improving the grading effect.

[0026] like Figures 1-3 As shown, a motor 16 is provided on one side of the main body 1, and the output shaft of the motor 16 is connected to the feed roller 4. One end of the rotating shaft 14 extends to the outside of the main body 1 and is provided with a belt 17 connected to the motor 16, which is used to drive the rotating shaft 14 and the feed roller 4 to rotate through the motor.

[0027] Based on the above structure, the rotation of motor 16, in conjunction with belt 17, drives shaft 14 and feed roller 4 to rotate synchronously, increasing the completeness of the equipment.

[0028] The working principle of this utility model is as follows: The air pump 11 is started, and its operating parameters are adjusted according to the classification requirements of the lead concentrate, causing the telescopic airbag 7 to inflate or deflate, thus moving the adjusting plate 6 and adjusting the volume of the feeding trough 5. The motor 16 is started, and it drives the rotating shaft 14 and the feeding roller 4 to rotate synchronously. The lead concentrate enters the collecting trough 2 through the feeding pipe 18, and the bidirectional spiral blades 15 flatten the lead concentrate to both sides. The flattened raw material enters the feeding trough 5, and with the rotation of the feeding roller 4, the subsequent classification of the lead concentrate is achieved. For the specific classification operation and working principle of the equipment, please refer to the double spiral classifier for lead concentrate processing and classification with authorization announcement number CN215823333U. Since this is not a technical point of this solution, it will not be described in detail.

[0029] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
