Description

Technical Field

[0001] This utility model relates to the field of flue gas treatment technology, specifically to an integrated three-stage sedimentation and transportation bin for high-temperature flue gas from tin smelting electric furnaces. Background Technology

[0002] During tin smelting, electric furnaces generate large amounts of high-temperature fumes carrying solid particles. Direct emission of these fumes would cause serious environmental pollution and resource waste. Therefore, they must be efficiently collected and treated using specialized settling equipment. Currently, the industry mostly uses physical methods such as gravity settling and cyclone separation for preliminary dust collection. However, for the high-temperature fumes generated by tin smelting electric furnaces, which have specific particle size distributions and physical characteristics, conventional single-stage or two-stage settling equipment often struggles to achieve efficient and comprehensive purification and recovery.

[0003] For example, a settling chamber for treating flue gas, as disclosed in patent publication number CN212467552U, includes a settling chamber body and a base. The settling chamber body is located on the upper outer surface of the base. A worm gear is installed inside the upper end of the settling chamber body. A gear is toothedly connected to one side of the worm gear, and a rack is toothedly connected to the outer surface of the gear. An activated carbon adsorption plate is fixedly connected to the lower outer surface of the rack. A water tank is fixedly installed on one side of the settling chamber body. The height has been increased from the original level, increasing the internal circulation space of the settling chamber, extending the time for flue gas to circulate and filter within the chamber, enhancing the cooling effect, and reducing the chamber temperature. The flue gas generated inside the settling chamber is then sprayed through spray nozzles to degrade the dust particles contained in the flue gas.

[0004] However, when the above-mentioned equipment is used to process high-temperature, high-concentration fumes with a wide particle size distribution generated by tin smelting electric furnaces, the settling method is relatively simple and the airflow organization is not optimized. As a result, the separation efficiency is not high, and some fine particles with lower density are carried out by the airflow before they have a chance to settle, which affects the final purification effect. Therefore, in order to address this issue, we propose a more convenient and practical three-stage settling integrated transport chamber for high-temperature fumes from tin smelting electric furnaces to meet the usage requirements. Utility Model Content

[0005] The purpose of this invention is to provide an integrated three-stage sedimentation and transportation silo for high-temperature dust from tin smelting electric furnaces, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a three-stage sedimentation integrated transport chamber for high-temperature dust from a tin smelting electric furnace, comprising a conveying assembly and a sedimentation mechanism; the sedimentation mechanism includes a primary sedimentation chamber, a secondary sedimentation chamber, and a tertiary sedimentation chamber, wherein a through hole is provided on one side of the bottom of the primary sedimentation chamber, and a first connecting pipe is fixedly connected inside the through hole, one end of the first connecting pipe being connected to the secondary sedimentation chamber; a through hole is provided on one side of the bottom of the secondary sedimentation chamber, and a second connecting pipe is fixedly connected inside the through hole, the second connecting pipe being connected to the tertiary sedimentation chamber.

[0007] Furthermore, the conveying assembly includes a support frame, with a plurality of integrated funnels fixedly connected to the bottom of the support frame, a first discharge pipe fixedly connected to the bottom of the integrated funnels, and a first solenoid valve installed on the outer wall of the first discharge pipe.

[0008] Furthermore, a conveyor belt is installed on one side of the bottom of the support frame.

[0009] Furthermore, an air inlet pipe is fixedly connected to the top of the primary settling chamber, a negative pressure motor is installed at one end of the air inlet pipe, and a fixing groove is fixedly connected to one side of the negative pressure motor.

[0010] Furthermore, a spiral plate is fixedly connected to one inner wall of the secondary settling chamber, a baffle is fixedly connected to one inner wall of the tertiary settling chamber, and an air outlet pipe is fixedly connected to one end of the tertiary settling chamber.

[0011] Furthermore, the primary, secondary, and tertiary settling chambers are all fixedly connected to support pipes at both ends, and a second solenoid valve is installed on the outer wall of the support pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This integrated three-stage settling and transport chamber for high-temperature dust from tin smelting electric furnaces, through the arrangement of transport components and settling mechanisms, allows high-temperature dust to be drawn into the primary settling chamber via an inlet pipe and fixed trough under the action of a negative pressure motor. In the primary settling chamber, larger particles begin to settle under gravity. Subsequently, the dust enters the secondary settling chamber through the first connecting pipe. The spiral plates in the secondary settling chamber rotate the dust, using centrifugal force to further settle smaller particles. Then, the dust enters the tertiary settling chamber through the second connecting pipe. Baffles change the direction of the dust flow, extending the residence time, allowing fine particles to settle. Relatively clean gas is discharged from the outlet pipe. Finally, the primary, secondary, and tertiary settling chambers are discharged under the action of a second solenoid valve and support pipe. This device improves the removal efficiency of solid particles in the dust through multi-stage settling, effectively reducing the dust content in subsequent emissions and minimizing environmental pollution. It is highly practical and suitable for widespread application.

[0013] At the same time, it can accurately control the discharge speed and amount of materials according to actual production needs and subsequent processing capacity, so as to avoid the impact of excessively fast or slow material discharge on subsequent processes. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] In the tin smelting process, dust settling equipment is required. The dust settling equipment provided by this utility model is specifically used for dust settling and transportation operations in the tin smelting process. During the settling and transportation operation using this equipment, it is necessary to ensure that the first solenoid valve 4 is in the open state when the settling particles are discharged so that the material in the integrated funnel 2 can be smoothly discharged to the conveyor belt 5 through the first discharge pipe 3. During the entire settling and transportation process, it is necessary to ensure that the conveyor belt 5 operates continuously and stably to transport the dust particles discharged from each settling chamber in a timely manner and prevent the material from accumulating and blocking the discharge pipe.

[0018] like Figures 1-3As shown, this utility model provides a technical solution: a three-stage sedimentation integrated transport bin for high-temperature dust from a tin smelting electric furnace, including a conveying assembly and a sedimentation mechanism 6; the sedimentation mechanism 6 includes a primary sedimentation bin 601, a secondary sedimentation bin 606, and a tertiary sedimentation bin 609. A through hole is opened on one side of the bottom of the primary sedimentation bin 601, and a first connecting pipe 605 is fixedly connected in the through hole. One end of the first connecting pipe 605 is connected to the secondary sedimentation bin 606. A through hole is opened on one side of the bottom of the secondary sedimentation bin 606, and a second connecting pipe 608 is fixedly connected in the through hole. The second connecting pipe 608 is connected to the tertiary sedimentation bin 609.

[0019] like Figure 2 As shown, the conveying assembly includes a support frame 1, with several integrated funnels 2 fixedly connected to the bottom of the support frame 1, a first discharge pipe 3 fixedly connected to the bottom of the integrated funnels 2, a first solenoid valve 4 installed on the outer wall of the first discharge pipe 3, and a conveyor belt 5 installed on one side of the bottom of the support frame 1.

[0020] It should be noted that the integrated funnel 2 collects materials falling from the settling mechanism 6 and other parts. The materials are temporarily stored in the integrated funnel 2. When discharge is required, the first solenoid valve 4 opens, and the materials are discharged through the first discharge pipe 3, falling into the conveyor belt 5 and being transported to the designated location. It can accurately control the discharge speed and discharge volume of materials according to actual production needs and subsequent processing capacity, avoiding the impact of excessively fast or slow material discharge on subsequent processes.

[0021] like Figure 3 As shown, an air inlet pipe 602 is fixedly connected to the top of the primary settling chamber 601. A negative pressure motor 603 is installed at one end of the air inlet pipe 602. A fixing groove 604 is fixedly connected to one side of the negative pressure motor 603. A spiral plate 607 is fixedly connected to one side of the inner wall of the secondary settling chamber 606. A baffle 610 is fixedly connected to one side of the inner wall of the tertiary settling chamber 609. An air outlet pipe 611 is fixedly connected to one end of the tertiary settling chamber 609. Support pipes 612 are fixedly connected to both ends of the primary settling chamber 601, the secondary settling chamber 606, and the tertiary settling chamber 609. A second solenoid valve 613 is installed on the outer wall of the support pipe 612.

[0022] It should be noted that the spiral plate 607 can also be replaced by a cyclone separator. During operation, high-temperature flue gas first enters the primary settling chamber 601 through the inlet pipe 602 and the fixed groove 604, under the action of the negative pressure motor 603. In the primary settling chamber 601, larger particles begin to settle under gravity. Subsequently, the flue gas enters the secondary settling chamber 606 through the first connecting pipe 605. The spiral plate 607 in the secondary settling chamber 606 rotates the flue gas, using centrifugal force to further settle smaller particles. Smoke and dust enter the third-stage settling chamber 609 through the second connecting pipe 608. The baffle 610 changes the direction of the smoke and dust flow and prolongs the residence time, causing small particles to settle. Relatively clean gas is discharged from the exhaust pipe 611. The final settling chamber 601, the second-stage settling chamber 606, and the third-stage settling chamber 609 are discharged under the action of the second solenoid valve 613 and the support pipe 612. The step-by-step settling process conforms to the law of particle settling, which can more effectively separate particles of different sizes and improve the performance of the entire settling system.

[0023] During operation, high-temperature flue gas first undergoes initial settling in the primary settling chamber 601, where large particles are separated. It then flows into the secondary settling chamber 606, where smaller particles are further settled by the action of the spiral plate 607. Finally, it enters the tertiary settling chamber 609, where tiny particles settle with the assistance of the baffle 610. Clean gas is discharged from the exhaust pipe 611. At the same time, the settled material falls into the integrated funnel 2, the first solenoid valve 4 is opened, and the material is discharged through the first discharge pipe 3 and conveyed to the designated location by the conveyor belt 5. This device improves the removal efficiency of solid particles in flue gas through multi-stage settling, effectively reducing the dust content in the subsequent emission gas and reducing environmental pollution.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
