Description

Technical Field

[0001] The present invention mainly relates to the technical field of water channel filtration, and particularly relates to a self-cleaning stepped lifting water filtration device. Background Art

[0002] The mechanical grille is one of the early purification devices in water supply and drainage treatment technology. It greatly reduces the labor intensity of workers, protects the health of workers, reduces the head loss of the influent, and improves the efficiency of the pumping station.

[0003] The commonly used existing filtration device is a mechanical grille, also known as a circulating toothed rake grille. This grille is a special water treatment device that can continuously and automatically intercept and remove various shaped debris in the fluid. It can be widely used in urban sewage treatment, the tap water industry, the intake of power plants, and can also be used as a pre-stage screening device in the wastewater treatment processes of industries such as textiles, food processing, papermaking, and leather. However, the existing filtration grilles all move continuously and cyclically from top to bottom driven by a motor and a reducer through a set of sheave wheels and chains. But this grille slot is easy to accumulate stains and cause blockage, and it is not easy to clean, thus affecting the filtration efficiency of the filtration device.

[0004] Therefore, in order to solve the situation of stain blockage of the filtration grille, a self-cleaning stepped lifting water filtration device is now proposed. Summary of the Invention

[0005] The present invention mainly provides a self-cleaning stepped lifting water filtration device to solve the technical problems raised in the above background art.

[0006] The technical solution adopted by the present invention to solve the above technical problems is as follows:

[0007] A self-cleaning stepped lifting water filtration device has an external fixed frame. Inside the top end of the external fixed frame, there is a power mechanism. On the two outer walls of the external fixed frame, there are eccentric mechanisms respectively. The driving end of the eccentric mechanism is connected to the power mechanism, and the execution end is connected to a stepped lifting filtration mechanism.

[0008] The stepped lifting filtration mechanism includes fixed filtration grille sheets fixed at the bottom of the external fixed frame. There are several of the fixed filtration grille sheets, which are successively fixed at the bottom of the external fixed frame. Below the external fixed frame and connected to the execution end of the eccentric mechanism is a lifting partition frame. At the top end of the lifting partition frame, there are lifting filtration grille sheets fixed. There are several of the lifting filtration grille sheets, which are successively fixed at the top end of the lifting partition frame. The lifting filtration grille sheets and the fixed filtration grille sheets are arranged alternately. When filtering, the eccentric mechanism drives the lifting filtration grille sheets to rotate up and down under the drive of the power mechanism to gradually lift the impurities on the fixed filtration grille sheets to the top of the external fixed frame for discharge.

[0009] Further, the eccentric mechanism includes a first eccentric wheel. The top end of the first eccentric wheel is rotationally connected to the external fixed frame housing through a rotating shaft. The first eccentric wheel is rotationally connected to an eccentric guide frame through a rotating shaft. The cross-section of the eccentric guide frame is in the shape of a right triangle. The bottom end of the end of the eccentric guide frame away from the first eccentric wheel is rotationally connected to a connecting rod through a rotating shaft. The end of the connecting rod away from the eccentric guide frame is rotationally connected to a second eccentric wheel through a rotating shaft. The top end of the second eccentric wheel is rotationally connected to the external fixed frame housing through a rotating shaft. The eccentric mechanism is symmetrically arranged with the external fixed frame as the center axis.

[0010] Further, the power mechanism includes a rotating guard plate. The rotating guard plate is fixed to the inner wall of the top end of the external fixed frame. A motor is fixed to the top surface of the rotating guard plate. The output shaft of the motor is connected to the input shaft of a three-axis reduction gear. A driven rotating shaft is provided on one side of the three-axis reduction gear. Both ends of the driven rotating shaft penetrate through the external fixed frame housing and extend to the outside and are respectively connected to the corresponding second eccentric wheels on the same side.

[0011] Further, an eccentric shaft gear is coaxially provided between each of the first eccentric wheel and the second eccentric wheel and the external fixed frame. The two eccentric shaft gears on the same side are connected by a chain.

[0012] Further, a support plate is fixed to the top end of the fixed filter grille sheet. Both ends of the support plate are fixed to the inner wall of the top end of the external fixed frame.

[0013] Further, each of the eccentric guide frames includes a longitudinal movement control rod. The top end of the longitudinal movement control rod is coaxially arranged with the corresponding first eccentric wheel on the same side. A transverse movement control rod is fixed to the end of the longitudinal movement control rod away from the corresponding first eccentric wheel. Each of the transverse movement control rods is perpendicular to the corresponding longitudinal movement control rod. The end of each of the transverse movement control rods away from the longitudinal movement control rod is coaxially arranged with the bottom end of the corresponding connecting rod.

[0014] Further, a reinforcing beam is fixed between the transverse movement control rod and the longitudinal movement control rod on the same side.

[0015] Further, a baffle is fixed to the surface of the transverse movement control rod, the longitudinal movement control rod, and the reinforcing beam on the same side away from the transverse movement control rod, the longitudinal movement control rod, and the reinforcing beam on the other side.

[0016] Further, both ends of the transverse movement control rod are rotationally connected to a support rod through a rotating shaft. The end of the support rod away from the corresponding transverse movement control rod is rotationally connected to the external fixed frame through a rotating shaft.

[0017] Furthermore, symmetrically arranged first movable grooves are formed in the bottom shell of the external fixing frame, and a second movable groove is formed in the top shell of the external fixing frame.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] First, when the water channel is flowing water, the present invention can lift the impurities in the water channel to the top of the filtering device step by step for discharge, thereby preventing the reduction of work efficiency due to filter shutdown. Specifically, through the cooperation of the eccentric mechanism and the lifting type filtering mechanism, when the lifting type filtering mechanism performs a rotary motion driven by the motor in the power mechanism, the lifting filter grid between the two eccentric guide frames follows the eccentric guide frame to perform a rotary motion. Since the lifting filter grid is coupled with the fixed filter grid in the external fixing frame, during the process of the lifting filter grid overlapping, misaligning, and separating from the fixed filter grid, since both the lifting filter grid and the fixed filter grid are stepped, the impurities on the fixed filter grid are gradually lifted to the top for discharge along with the rotary motion of the lifting filter grid.

[0020] Second, when the eccentric guide frame rotates, the present invention can support multiple vertices of the eccentric guide frame to improve the operating stability of the eccentric guide frame. Since the eccentric guide frame and the connecting rod respectively form the rotation points of the vertices of the eccentric guide frame and the connecting rod through the first eccentric wheel, the second eccentric wheel, and the two support rods rotatably connected thereto, the rotational stability of the eccentric guide frame and the connecting rod is improved.

[0021] Third, the present invention does not require backwashing water for cleaning, and achieves the self-cleaning effect through the relative movement of the lifting filter grid and the fixed filter grid.

[0033] Please refer again with emphasis to the attached Figure 1-4, A self-cleaning stepped lifting water filtration device, comprising an external fixed frame 1, characterized in that a power mechanism 2 is provided inside the top end of the external fixed frame 1, eccentric mechanisms 3 are respectively provided on two outer walls of the external fixed frame 1, the driving end of the eccentric mechanism 3 is connected to the power mechanism 2, and the execution end is connected to a lifting filtration mechanism 4. The lifting filtration mechanism 4 includes fixed filtration grille sheets 41 fixed to the bottom of the external fixed frame 1. There are several fixed filtration grille sheets 41, which are sequentially fixed to the bottom of the external fixed frame 1. Below the external fixed frame 1 and connected to the execution end of the eccentric mechanism 3 is a lifting partition frame 43. A lifting filtration grille sheet 42 is fixed to the top end of the lifting partition frame 43. There are several lifting filtration grille sheets 42, which are sequentially fixed to the top end of the lifting partition frame 43. The lifting filtration grille sheets 42 and the fixed filtration grille sheets 41 are arranged alternately. When filtering, the eccentric mechanism 3 drives the lifting filtration grille sheets 42 to rotate up and down under the drive of the power mechanism 2, so as to gradually lift the impurities on the fixed filtration grille sheets 41 to the top of the external fixed frame 1 for discharge.

[0034] Please refer to the appendix Figure 1 and 2 , The eccentric mechanism 3 includes a first eccentric wheel 31. The top end of the first eccentric wheel 31 is rotationally connected to the shell of the external fixed frame 1 through a rotating shaft. The first eccentric wheel 31 is rotationally connected to an eccentric guide frame 32 through a rotating shaft. The cross-section of the eccentric guide frame 32 is in the shape of a right triangle. The bottom end of the end of the eccentric guide frame 32 away from the first eccentric wheel 31 is rotationally connected to a connecting rod 33 through a rotating shaft. The end of the connecting rod 33 away from the eccentric guide frame 32 is rotationally connected to a second eccentric wheel 34 through a rotating shaft. The top end of the second eccentric wheel 34 is rotationally connected to the shell of the external fixed frame 1 through a rotating shaft. The eccentric mechanism 3 is symmetrically arranged with the external fixed frame 1 as the center.

[0035] Please refer to the appendix Figure 2 , The power mechanism 2 includes a rotating guard plate 21. The rotating guard plate 21 is fixed to the inner wall of the top end of the external fixed frame 1. A motor 22 is fixed to the top surface of the rotating guard plate 21. The output shaft of the motor 22 is connected to the input shaft of a three-axis speed reducer 23. A driven rotating shaft 24 is provided on one side of the three-axis speed reducer 23. Both ends of the driven rotating shaft 24 penetrate through the shell of the external fixed frame 1 and extend to the outside and are respectively connected to the corresponding second eccentric wheel 34 on the same side. The output shaft of the motor 22 drives the three-axis speed reducer 23 connected to it to rotate.

[0036] Please refer specifically to the appendix Figure 2, an eccentric shaft gear 35 is coaxially arranged between each of the first eccentric wheel 31 and the second eccentric wheel 34 and the external fixed frame 1. The two eccentric shaft gears 35 on the same side are connected by a chain. When one of the eccentric shaft gears 35 rotates following the first eccentric wheel 31, since this eccentric shaft gear 35 is connected to the eccentric shaft gear 35 on the second eccentric wheel 34 through the chain, the first eccentric wheel 31 and the second eccentric wheel 34 are driven to rotate synchronously.

[0037] Please refer to the appendix again Figure 2 , both ends of the transverse movement control rod 322 are rotatably connected to a support rod 324 through a rotating shaft. One end of each support rod 324 away from the corresponding transverse movement control rod 322 is rotatably connected to the external fixed frame 1 through a rotating shaft, so that the eccentric guide frame 32 and the connecting rod 33 respectively form the rotation points of the apex angles of the eccentric guide frame 32 and the connecting rod 33 through the first eccentric wheel 31, the second eccentric wheel 34 and the two support rods 324 rotatably connected thereto, thereby improving the rotation stability of the eccentric guide frame 32 and the connecting rod 33.

[0038] Please refer to the appendix emphatically Figure 3 and 6 , symmetrically arranged first movable grooves 12 are opened on the bottom shell of the external fixed frame 1, so that the external fixed frame 1 reserves enough space for the lifting of the filter grid sheet 42 and the lifting frame 43 to move through the symmetrically arranged first movable grooves 12 at its bottom. A second movable groove 11 is opened on the top shell of the external fixed frame 1, thereby reserving enough space through the second movable groove 11 on the external fixed frame 1 to communicate with the grid residue treatment device.

[0039] Please refer to the appendix again Figure 3 and 6 , a support plate 44 is fixed to the top of the fixed filter grid sheet 41. Both ends of the support plate 44 are fixed to the inner wall of the top of the external fixed frame 1, so that the top of the fixed filter grid sheet 41 is connected to the inner wall of the top of the external fixed frame 1 through the support plate 44, and the welding of the fixed filter grid sheet 41 is facilitated by the fixation of the support plate 44.

[0040] Please refer to the appendix Figure 4 , baffles 325 are fixed to the surfaces of the transverse movement control rod 322, the longitudinal movement control rod 321 and the reinforcing beam 323 on the same side away from the transverse movement control rod 322, the longitudinal movement control rod 321 and the reinforcing beam 323 on the other side, so as to use the baffles 325 to resist the impact on the transverse movement control rod 322, the longitudinal movement control rod 321 and the reinforcing beam 323 from the outside.

[0041] Please refer to the appendix emphatically Figure 4, each of the eccentric guide frames 32 includes a longitudinal motion control rod 321. The top end of the longitudinal motion control rod 321 is coaxially arranged with the corresponding first eccentric wheel 31 on the same side. A transverse motion control rod 322 is fixed to the end of the longitudinal motion control rod 321 away from the corresponding first eccentric wheel 31. Each of the transverse motion control rods 322 is perpendicular to the corresponding longitudinal motion control rod 321. The end of each transverse motion control rod 322 away from the longitudinal motion control rod 321 is coaxially arranged with the bottom end of the corresponding connecting rod 33, so that the transverse motion control rod 322 rotates following the connecting rod. A reinforcing beam 323 is fixed between the transverse motion control rod 322 and the longitudinal motion control rod 321 on the same side. Thus, the transverse motion control rod 322, the longitudinal motion control rod 321 and the reinforcing beam 323 respectively form the three sides of a right triangle, thereby strengthening the structural strength of the eccentric guide frame 32 by using the stable triangular structure.

[0042] The specific operation mode of the present invention is as follows:

[0043] When using the filtering device to filter the water in the water diversion channel, start the motor 22 in the power mechanism 2. When the output shaft of the motor 22 drives the three-axis speed reducer 23 connected to it to rotate, since one end of the first eccentric wheel 31 away from the output shaft of the three-axis speed reducer 23 is rotatably connected to the top end of the eccentric guide frame 32, one end of the eccentric guide frame 32 is driven to revolve around the output shaft of the three-axis speed reducer 23 as the rotation center. At this time, since one of the eccentric shaft gears 35 rotates following the first eccentric wheel 31, and this eccentric shaft gear 35 is connected to the eccentric shaft gear 35 on the second eccentric wheel 34 through a chain, the first eccentric wheel 31 and the second eccentric wheel 34 are driven to rotate synchronously. During this process, since the connecting rod 33 rotatably connected to the eccentric guide frame 32 is rotatably connected to the second eccentric wheel 34, the eccentric guide frame 32 is driven to perform a rotary motion. When the lifting filter grid plate 42 between the two eccentric guide frames 32 performs a rotary motion following the eccentric guide frame 32, since the lifting filter grid plate 42 is coupled with the fixed filter grid plate 41 in the external fixed frame 1, the process of overlapping, misaligning and separating between the lifting filter grid plate 42 and the fixed filter grid plate 41 occurs. Since both the lifting filter grid plate 42 and the fixed filter grid plate 41 are stepped, the impurities on the fixed filter grid plate 41 are gradually lifted to the top and discharged as the lifting filter grid plate 42 performs a rotary motion.

[0044] The above has described the present invention by way of example in conjunction with the drawings. Obviously, the specific implementation of the present invention is not limited by the above methods. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
