Description

Technical Field

[0001] This utility model relates to the field of dual-line ash conveying technology, and in particular to a dual-line ash conveying device for electrostatic precipitators. Background Technology

[0002] In modern industrial production, electrostatic precipitators, as a highly efficient air purification device, are widely used in many industries such as power, metallurgy, building materials, and chemicals. Their working principle is to use a high-voltage electric field to charge the dust particles in the flue gas, and then, under the action of the electric field force, adsorb the dust particles onto the electrodes, thereby achieving the purpose of purifying the flue gas and reducing dust emissions. With increasingly stringent environmental protection requirements, electrostatic precipitators are playing an increasingly crucial role in industrial flue gas treatment, effectively reducing air pollutant emissions and improving environmental quality.

[0003] Most of the ash conveying devices commonly found on the market adopt a single-line conveying mode. This mode is often difficult to meet the high-efficiency ash conveying requirements when facing large-scale industrial production. Traditional single-line ash conveying devices lack fault redundancy design. Once the conveying line fails, such as the screw conveyor jamming, the pipeline blockage, or the motor damage, the entire ash conveying process will be forced to stop. At this time, the dust in the electrostatic precipitator cannot be discharged in time and can only be stopped for maintenance, resulting in production interruption and economic losses.

[0004] To address the aforementioned problems with traditional ash conveying devices, it is essential to develop a dual-line ash conveying device for electrostatic precipitators. This device would meet the ash conveying needs of large-scale industrial production, ensuring that if one conveying line fails, the other can continue operating normally, preventing the entire conveying process from being interrupted and guaranteeing the continuity and stability of production. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a dual-line ash conveying device for electrostatic precipitators.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A dual-line ash conveying device for an electrostatic precipitator includes an inner cylinder, an agitator installed inside the inner cylinder, a heating component mounted on the inner cylinder, and an ash conveying component installed at the bottom of the inner cylinder. The ash conveying component includes a rotary joint, an electromagnetic control valve, and a connecting pipe. The electromagnetic control valve is fixed to the outer wall of the bottom of the inner cylinder, and the connecting pipe is movably connected to the bottom of the electromagnetic control valve through the rotary joint. A screw conveying component is fixed to the bottom of the connecting pipe, and a discharge pipe is fixed to the bottom of the screw conveying component.

[0008] As a further embodiment of this utility model: the heating component includes an outer cover and a heating component, the heating component is installed in a ring on the outer wall of the inner cylinder, and the outer cover is fixed to the inner wall at the bottom of the inner cylinder.

[0009] As a further embodiment of this utility model: a cover plate is fixed to the top outer wall of the inner cylinder, and the stirring assembly includes a control motor and a rotating shaft. The control motor is fixed to the top outer wall of the cover plate, and the rotating shaft is connected to the output end of the control motor through a coupling. An stirring frame is fixed to the outer wall of the rotating shaft.

[0010] As a further improvement of this utility model: a scraper is movably connected to the end of the stirring frame, and a spring is installed between the outer wall of one side of the scraper and the inner wall of the stirring frame.

[0011] As a further embodiment of this utility model: a mounting bracket is fixed to the outer wall of the bottom of the inner cylinder, and a drive motor is fixed to the inner wall of the bottom of the mounting bracket. A second gear is fixed to the output end of the drive motor by a pin, and a first gear that meshes with the second gear is fixed to the outer wall of the circumference of the connecting pipe.

[0012] As a further improvement of this utility model: the bottom of the spiral conveyor assembly is fixed with a support leg, and the bottom of the support leg is movably connected with a universal wheel.

[0013] As a further improvement of this utility model, a hopper is fixed to the outer wall of the top of the cover plate.

[0014] As a further improvement of this utility model: a bracket is fixed to the outer wall of the outer cover, and a controller is fixed on the bracket.

[0015] Compared with the prior art, this utility model provides a dual-line ash conveying device for electrostatic precipitators, which has the following beneficial effects:

[0016] This application achieves a dual-line operation mode for dust conveying by setting up two sets of spiral conveyor components. During normal production, the two conveyor lines can work simultaneously, which significantly improves the dust conveying efficiency and meets the needs of large-scale production. When one conveyor line fails, the other conveyor line can still operate normally and continue to convey dust, avoiding the entire conveying process from being interrupted due to a single line failure.

[0017] The heating element on the inner cylinder transfers heat to the dust inside, thoroughly drying the dust containing moisture. The stirring element inside the inner cylinder, driven by the control motor, rotates the stirring frame to agitate the dust, making the dust heated more evenly. The dried dust avoids the sticking problem caused by moisture, making it smoother to be transported by the screw conveyor component and reducing the risk of blockage during the transportation process.

[0018] In actual production, once one loading and unloading device is full of dust, there is no need to wait for the loading and unloading device to leave and for another loading and unloading device to enter and adjust the loading and unloading position. The controller can simply control the drive motor to rotate the second gear, which in turn drives the first gear and the connecting pipe to rotate, quickly rotating the discharge pipe to the top of another pre-prepared loading and unloading device, and the dust loading can start again. This design greatly shortens the loading interval time and effectively improves the dust loading efficiency.

[0019] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Dual-line ash conveying devices for electrostatic precipitators, such as Figures 1 to 5As shown, the device includes an inner cylinder 19, inside which an agitation assembly is installed, and a heating assembly is provided on the inner cylinder 19. An ash conveying assembly is installed at the bottom of the inner cylinder 19. The ash conveying assembly includes a rotary joint 3, an electromagnetic control valve 7, and a connecting pipe 8. The electromagnetic control valve 7 is fixed to the outer wall of the bottom of the inner cylinder 19, and the connecting pipe 8 is rotatably connected between the rotary joint 3 and the bottom of the electromagnetic control valve 7. A screw conveying assembly 12 is fixed at the bottom of the connecting pipe 8, and a discharge pipe 9 is fixed at the bottom of the screw conveying assembly 12.

[0028] The inner cylinder 19 can be used to temporarily store the dust that needs to be transported. The heating component on the inner cylinder 19 can be used to heat the dust. The purpose of heating is to dry the dust when it contains moisture, so as to prevent the dust from clumping due to moisture and affecting subsequent transport.

[0029] The agitation component inside the inner cylinder 19 agitates the dust while it is drying, resulting in more uniform heating. After drying, the solenoid control valve 7 is opened, allowing the dust to enter the connecting pipe 8 through the valve and rotary joint 3. After passing through the connecting pipe 8, the dust is conveyed by the screw conveyor assembly 12. The screw conveyor assembly 12 uses rotating screw blades to push and convey the material along the inner wall of the casing. The motor drives the screw shaft to rotate, and the material is continuously and stably conveyed within the closed casing under the pushing force of the screw blades and its own gravity. The working principle of the screw conveyor assembly 12 is existing technology and will not be described in detail here.

[0030] The dust conveyed by the screw conveyor assembly 12 is finally discharged through the discharge pipe 9. In the actual production process, the loading and unloading device can be moved to the bottom of the discharge pipe 9 to collect and transfer the dust.

[0031] By setting up two sets of spiral conveyor components 12, the dust conveying can achieve dual-line operation, which improves the conveying efficiency and allows the other conveyor to convey dust normally when one conveyor fails, avoiding the interruption of the entire conveying process. By setting up a rotary joint 3, the position of the discharge pipe 9 can be adjusted in the horizontal direction. When one loading and unloading device is loading, the other loading and unloading device is prepared in advance. When the previous loading and unloading device is full, the discharge pipe 9 can be rotated to the top of the other loading and unloading device to reload dust. Compared with the other loading and unloading device being moved in to adjust the loading and unloading position after one loading and unloading device is full, the loading efficiency can be effectively improved.

[0032] The heating assembly includes an outer cover 1 and a heating component 18. The heating component 18 is installed in a ring on the outer circumference of the inner cylinder 19, and the outer cover 1 is fixed to the inner bottom wall of the inner cylinder 19.

[0033] The heating component 18 can be covered by an outer cover 1. The inner wall of the outer cover 1 is covered with insulation materials such as insulation cotton to effectively reduce heat loss. The heating component 18 preferably uses an electric heating wire for heating, and the inner cylinder 19 is used to transfer heat to the dust to dry the dust.

[0034] The top outer wall of the inner cylinder 19 is fixed with a cover plate 17 by bolts, and the agitation assembly includes a control motor 16 and a rotating shaft 21. The control motor 16 is fixed to the top outer wall of the cover plate 17 by bolts, and the rotating shaft 21 is connected to the output end of the control motor 16 by a coupling. An agitator 20 is fixed to the outer wall of the rotating shaft 21, and a scraper 22 is slidably connected to the end of the agitator 20. A spring 23 is installed between the outer wall of one side of the scraper 22 and the inner wall of the agitator 20.

[0035] When the control motor 16 drives the agitator 20 to rotate, it can agitate the dust inside the inner cylinder 19.

[0036] The bottom outer wall of the inner cylinder 19 is fixed with a mounting bracket 14 by bolts, and the bottom inner wall of the mounting bracket 14 is fixed with a drive motor 15 by bolts. The output end of the drive motor 15 is fixed with a gear 2 13 by a pin, and the outer circumference of the connecting pipe 8 is fixed with a gear 1 4 that meshes with the gear 2 13.

[0037] The drive motor 15 can drive the gear 2 13 to rotate. During the rotation of the gear 2 13, the gear 14 and the connecting pipe 8 are driven to rotate, thereby adjusting the position of the feed pipe 9 in a certain range in the horizontal direction.

[0038] The bottom of the spiral conveyor assembly 12 is fixed with a support leg 11 by bolts, and the bottom of the support leg 11 is rotatably connected with a caster wheel 10.

[0039] The casters 10 and outriggers 11 provide auxiliary support during the rotation of the feed pipe 9 and the screw conveyor assembly 12.

[0040] The hopper 2 is fixed to the top outer wall of the cover plate 17 by bolts.

[0041] By connecting the hopper 2 and the electrostatic precipitator (not shown), dust enters the inner cylinder 19 through the electrostatic precipitator and the hopper 2.

[0042] The outer wall of the outer cover 1 is fixed with a bracket 6 by bolts.

[0043] The device can be supported by the bracket 6.

[0044] The controller 5 is fixed on the bracket 6.

[0045] The controller 5 can regulate the start-up, shutdown, and operating parameters of the control motor 16, drive motor 15, electromagnetic control valve 7, and heating component 18, thereby agitating and drying the dust in the inner cylinder 19, controlling the timing of dust entering the connecting pipe 8, and adjusting the position of the discharge pipe 9 to ensure the stable and orderly operation of the entire dual-line ash conveying device.

[0046] Working principle: First, hopper 2 is connected to the electrostatic precipitator. The dust collected by the electrostatic precipitator enters the inner cylinder 19 through hopper 2 for temporary storage. Controller 5 controls the heating component 18 to work, using the inner cylinder 19 to transfer heat to the dust, drying the dust containing moisture and preventing it from sticking together and affecting subsequent conveying. At the same time, controller 5 starts the control motor 16, which drives the rotating shaft 21 to rotate through the coupling. The agitator 20 fixed on the outer wall of the rotating shaft 21 rotates accordingly, agitating the dust inside the inner cylinder 19 and ensuring uniform heating. After the dust is dried, controller 5 controls the solenoid control valve 7 to open, and the dust enters the connecting pipe 8 through the solenoid control valve 7 and the rotary joint 3. A screw conveyor component 12 is fixed at the bottom of the connecting pipe 8. The conveying assembly 12 uses rotating spiral blades to push and convey dust along the inner wall of the casing. The motor drives the spiral shaft to rotate, and the dust is continuously and stably conveyed in the closed casing under the push of the spiral blades and its own gravity. During the conveying process, if it is necessary to adjust the position of the discharge pipe 9, the controller 5 controls the drive motor 15 to work. The gear 13 fixed at the output end of the drive motor 15 rotates, which drives the gear 4 that meshes with the gear 13 and is fixed on the outer circumference of the connecting pipe 8 to rotate, thereby causing the connecting pipe 8 to rotate and realize the horizontal position adjustment of the discharge pipe 9. When the next loading and unloading fixture is ready in advance, after the previous loading and unloading fixture is full, the discharge pipe 9 can be rotated to the top of another loading and unloading fixture to reload dust, thereby improving loading efficiency.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
