Description

Technical Field

[0001] The invention relates to the technical field of garbage treatment equipment, and in particular to a garbage incineration fly ash treatment device. Background Art

[0002] Domestic waste incineration technology has developed rapidly in my country in recent years due to its high degree of reduction in quantity and volume. Domestic waste incineration produces fly ash equivalent to 3% to 5% of the original waste mass, which contains heavy metals such as Zn, Cu, Cd, Pb, Cr, a large number of soluble salts mainly composed of chlorides, and persistent organic pollutants such as dioxins. It is an internationally recognized hazardous waste. In the existing technology, fly ash is usually collected by dissolving fly ash in water, but this method wastes a lot of water resources and is prone to secondary pollution when discharged. Summary of the invention

[0003] The present invention is intended to provide a waste incineration fly ash treatment device, to provide a treatment device using a filter screen to treat fly ash, so as to overcome the problem that the prior art wastes a large amount of water resources and easily causes secondary pollution during discharge.

[0004] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a waste incineration fly ash treatment device, comprising a treatment box and a negative pressure machine, the treatment box is provided with a stepper motor, a fly ash inlet and a fly ash outlet, an annular filter screen is also provided inside the treatment box between the fly ash inlet and the fly ash outlet, a plurality of connecting rods are fixedly provided between the movable end of the stepper motor and the annular filter screen; an ash removal box is fixedly provided in the treatment box, the bottom of the annular filter screen passes through the ash removal box, the ash removal box is provided with a transverse slide groove, the slide groove is slidably connected with a sliding plate, the sliding plate is provided with bristles in contact with the annular filter screen, and one side of the ash removal box is fixed A cylinder is provided, a support rod is rotatably connected between the movable end of the cylinder and the sliding plate, a cleaning motor and a deashing rod are fixedly provided on the other side of the ash removing box, the movable end of the cleaning motor is fixedly sleeved with a driving gear, the ash removing box is rotatably connected with a driving rod coaxial with the support rod, the driving rod is fixedly sleeved with a driven gear meshing with the driving gear, the sliding plate is provided with a center hole and a driving hole connected with the center hole, the driving rod passes through the center hole and is provided with a driving wing located in the driving hole, the ash removing box is provided with a negative pressure pipe and a deashing rod in contact with brush bristles on both sides, the negative pressure machine is connected to the negative pressure pipe, and the sliding plate is provided with a notch for the deashing rod to slide.

[0005] The working principle and beneficial effects of the present invention: In this scheme, fly ash enters the processing box from the fly ash inlet. Since the annular filter screen is located between the fly ash inlet and the fly ash outlet, the fly ash passes through the annular filter screen to be filtered twice and then flies out from the fly ash outlet, and the harmful impurities in the fly ash are trapped on the annular filter screen.

[0006] After a period of use, the side of the annular filter screen facing the fly ash inlet and fly ash outlet is covered with a large amount of impurities, thereby losing or weakening the ability to filter fly ash. Since a plurality of connecting rods are fixed between the active end of the stepper motor and the annular filter screen, the annular filter screen is driven to rotate by the stepper motor, and the position of the annular filter screen is adjusted so that the unused part of the annular filter screen rotates to face the fly ash inlet and fly ash outlet, thereby continuing to maintain a good filtering effect on fly ash.

[0007] The part of the annular filter that is covered with impurities moves to the ash removal box, and the stepper motor controls the annular filter to rotate forward and reverse alternately, and the annular filter continues to filter the fly ash. Since the sliding plate and the horizontal slideway are slidably connected, the bristles set on the sliding plate are in contact with the annular filter, and the direction of the slideway is perpendicular to the direction of rotation of the annular filter. The rotation of the annular filter will not push the sliding plate to slide, so that the bristles keep in contact with the annular filter. In the process of the annular filter rotating forward and reverse alternately, the bristles repeatedly wipe and clean the impurities on the annular filter, and a large amount of impurities are attached to the bristles.

[0008] After the bristles have been used for a period of time, they are covered with a lot of impurities and lose their cleaning ability, so they need to be cleaned. In this solution, a support rod is rotatably connected between the movable end of the cylinder and the sliding plate. By starting the cylinder, the movable end of the cylinder pushes the sliding plate toward the cleaning motor through the support rod. During this process, the driving rod is inserted into the center hole of the sliding plate, and the driving wing is inserted into the driving hole. As the sliding plate continues to move, the sliding plate slips out of the slide slot, and the slide slot does not limit the sliding plate. The driving wing and the driving rod are fully inserted, and the bristle part contacts the deashing rod.

[0009] Start the cleaning motor and the negative pressure machine. The cleaning motor drives the active gear to rotate alternately clockwise and counterclockwise at a certain angle, and then drives the driving rod to rotate alternately clockwise and counterclockwise at a certain angle through the driven gear. The support rod is connected to the sliding plate, and the support rod will not affect the rotation of the sliding plate. The driving rod drives the sliding plate to rotate alternately clockwise and counterclockwise at a certain angle through the driving wing and the driving hole. The sliding plate drives the bristles to rotate alternately. The bristles contact the deashing rod and bounce off the impurities and dust. The negative pressure machine generates negative pressure and sucks out the impurities and dust through the negative pressure pipe. After the cleaning is completed, the cleaning motor works to make the sliding plate rotate to face the slide slot, and the cylinder drives the support rod to move away from the cleaning motor, so that the sliding plate slides into the slide slot, the driving rod and the driving wing are separated from the center hole and the driving hole, and the bristles are in contact with the annular filter again.

[0010] The present invention provides a treatment device for treating fly ash using a filter screen, so as to overcome the existing method of dissolving fly ash in water, thereby avoiding wasting a large amount of water resources, and collecting impurities and dust through a negative pressure machine to avoid secondary pollution.

[0011] Furthermore, the deliming rod is fixed with a plurality of deliming teeth, and the plurality of deliming teeth are evenly spaced along the axis of the deliming rod. When the bristles continuously strike the deliming rod back and forth, the plurality of deliming teeth can smooth the bristles and scrape off impurities attached to the bristles.

[0012] Furthermore, a plurality of the deliming teeth extend to the root of the bristles, so that the deliming teeth are arranged in this way, the cleaning effect on the bristles is better.

[0013] Furthermore, the cleaning motor is electrically connected to a controller, and the controller is electrically connected to the cylinder. The controller can accurately control the rotation angle of the active end of the cleaning motor and can also control the telescopic stroke of the active end of the cylinder.

[0014] Furthermore, the number of the deliming rods is 3, and the 3 deliming rods are arranged in a triangle orientation.

[0015] Furthermore, the number of the bristles is multiple, and multiple bristles can better clean the annular filter.

[0016] When the bristles are in contact with the three deliming rods, the three deliming rods are arranged in a triangular orientation, the deliming rod at the top is in contact with the side of the bristles close to the sliding plate (the root of the bristles), and the deliming rods at both sides are in contact with the bottom of the bristles. The bottom of the bristles is in contact with the filter for a long time, so that the bristles gradually expand outward from their roots toward the outer contour of their bottoms, presenting a triangular shape as a whole. When the bristles swing, the top deliming rod is in contact with the roots of the bristles, and the contour size of the top of the bristles is small, so that the roots of multiple bristles gather together, and the top deliming rod can push the roots of multiple bristles, so that the multiple bristles swing quickly, and the bottoms of the multiple bristles are quickly brushed by the other two deliming rods, thereby achieving a better cleaning effect on the multiple bristles.

[0017] Furthermore, the annular filter screen extends to the treatment box. Such an annular filter screen can block the treatment box, so that the fly ash can completely pass through the annular filter screen, thereby improving the filtering effect. BRIEF DESCRIPTION OF THE DRAWINGS

In practice, if the corresponding structures are changed in the same direction based on the directions while keeping the relative positions unchanged, it will not affect the implementation of the plan.

[0023] Embodiment: A waste incineration fly ash treatment device, such as Figure 1 and Figure 2 As shown, it includes a processing box 5 and a negative pressure machine. The processing box 5 is provided with a stepper motor 9, a fly ash inlet 4 and a fly ash outlet 8. An annular filter screen 3 is also provided inside the processing box 5 between the fly ash inlet 4 and the fly ash outlet 8. A plurality of connecting rods 7 are fixedly provided between the movable end of the stepper motor 9 and the annular filter screen 3. The processing box 5 is fixedly provided with an ash removal box 2. The bottom of the annular filter screen 3 passes through the ash removal box 2. The ash removal box 2 is provided with a transverse slide groove. The slide groove is slidably connected with a sliding plate 16. The sliding plate 16 is provided with bristles 17 that contact the annular filter screen 3. A cylinder is fixedly provided on one side of the ash removal box 2. The movable end of the cylinder and the sliding plate 16 are rotatably connected. It is connected to a support rod 11, and a cleaning motor 13 and a deashing rod 15 are fixedly arranged on the other side of the ash removal box 2. The movable end of the cleaning motor 13 is fixedly sleeved with a driving gear 12. The ash removal box 2 is rotatably connected to a driving rod 1 coaxial with the support rod 11. The driving rod 1 is fixedly sleeved with a driven gear 14 meshing with the driving gear 12. The sliding plate 16 is provided with a center hole and a driving hole connected to the center hole. The driving rod 1 passes through the center hole and is provided with a driving wing located in the driving hole. The ash removal box 2 is provided with a negative pressure pipe 10 and a deashing rod 15 in contact with bristles 17 on both sides. The negative pressure machine is connected to the negative pressure pipe 10, and the sliding plate 16 is provided with a notch for the deashing rod 15 to slide.

[0024] In this scheme, fly ash enters the processing box 5 from the fly ash inlet 4. Since the annular filter screen 3 is located between the fly ash inlet 4 and the fly ash outlet 8, the fly ash passes through the annular filter screen 3 for two filtrations and then flies out from the fly ash outlet 8. The harmful impurities in the fly ash are retained on the annular filter screen 3.

[0025] like Figure 3As shown, after a period of use, the side of the annular filter 3 facing the fly ash inlet 4 and the fly ash outlet 8 is covered with a large amount of impurities, thereby losing or weakening the filtering ability of the fly ash. Since a plurality of connecting rods 7 are fixedly arranged between the movable end of the stepper motor 9 and the annular filter 3, the annular filter 3 is driven to rotate by the stepper motor 9, and the position of the annular filter 3 is adjusted so that the unused part of the annular filter 3 rotates to face the fly ash inlet 4 and the fly ash outlet 8, thereby continuing to maintain a good filtering effect on the fly ash.

[0026] The part of the annular filter 3 that is covered with impurities moves into the ash removal box 2, and the stepper motor 9 controls the annular filter 3 to rotate forward and reverse alternately, and the annular filter 3 continues to filter the fly ash. Since the sliding plate 16 is slidably connected to the horizontal slideway, the bristles 17 provided on the sliding plate 16 are in contact with the annular filter 3, and the direction of the slideway is perpendicular to the direction of rotation of the annular filter 3, the rotation of the annular filter 3 will not push the sliding plate 16 to slide, so that the bristles 17 remain in contact with the annular filter 3, and the annular filter 3 rotates forward and reverse alternately. The bristles 17 repeatedly wipe and clean the impurities on the annular filter 3, and a large amount of impurities are attached to the bristles 17.

[0027] After the bristles 17 have been used for a period of time, they are covered with a large amount of impurities and lose their cleaning ability, so it is necessary to clean the bristles 17. In this solution, the support rod 11 is rotatably connected between the movable end of the cylinder and the sliding plate 16. By starting the cylinder, the movable end of the cylinder pushes the sliding plate 16 toward the cleaning motor 13 through the support rod 11. During this process, the driving rod 1 is inserted into the center hole of the sliding plate 16, and the driving wing is inserted into the driving hole. As the sliding plate 16 continues to move, the sliding plate 16 escapes from the slide slot, and the slide slot does not limit the sliding plate 16. The driving wing and the driving rod 1 are fully inserted, and at this time, the bristles 17 are partially in contact with the deashing rod 15.

[0028] Start the cleaning motor 13 and the negative pressure machine, the cleaning motor 13 drives the driving gear 12 to rotate alternately clockwise and counterclockwise at a certain angle, and then drives the driving rod 1 to rotate alternately clockwise and counterclockwise at a certain angle through the driven gear 14, and the support rod 11 is connected to the sliding plate 16, the support rod 11 will not affect the rotation of the sliding plate 16, the driving rod 1 drives the sliding plate 16 to rotate alternately clockwise and counterclockwise at a certain angle through the driving wing and the driving hole, the sliding plate 16 drives the bristles 17 to rotate alternately, the bristles 17 contact the deashing rod 15, and the impurities and dust are ejected, the negative pressure machine generates negative pressure, and the impurities and dust are sucked out through the negative pressure pipe 10. After the cleaning is completed, the cleaning motor 13 works, so that the sliding plate 16 rotates to face the chute, the cylinder drives the support rod 11 to move away from the cleaning motor 13, so that the sliding plate 16 slides into the chute, the driving rod 1 and the driving wing are separated from the center hole and the driving hole, and the bristles 17 and the annular filter 3 are re-contacted.

[0029] This solution provides a processing device for processing fly ash using a filter screen 3, so as to overcome the existing technology of using fly ash to dissolve in water, thereby avoiding wasting a large amount of water resources, and collecting impurities and dust through a negative pressure machine to avoid secondary pollution.

[0030] For those skilled in the art, multiple variations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The protection scope required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
