Description

Technical Field

[0001] This application relates to the technical field of wastewater treatment, and in particular to an internal flow bar screen cleaner with easily removable fibers. Background Technology

[0002] A bar screen is a pre-filtration device used in water or wastewater treatment processes. Its core function is to intercept and remove large suspended and floating solids from the water flow. The internal flow bar screen is one type of bar screen, characterized by wastewater flowing in from the inside of the screen and out from the outside. The rotating screen intercepts and removes debris from the water, and it is commonly used in wastewater treatment plants and pumping stations.

[0003] In existing technologies, internal flow bar screens introduce sewage from the side, using a moving bar screen to intercept impurities in the water, which then flows out from the side, thus achieving the interception of impurities on the sewage surface. However, Regarding the aforementioned technologies, the inventors believe that during the sewage treatment process, the sewage impurities contain hair, fibers, and other impurities that easily become entangled on the inner side of the bar screen. This can affect the normal filtration of the bar screen and also affect its normal rotation, thereby reducing the applicability of the internal flow bar screen. Utility Model Content

[0004] To improve the applicability of bar screen cleaning machines, this application provides an internal flow bar screen cleaning machine that facilitates fiber removal.

[0005] The internal flow bar screen cleaner with easily removable fibers provided in this application adopts the following technical solution: An easily removable internal flow bar screen cleaning machine includes a bar screen conveyor belt, a mounting frame, and a cleaning assembly. The bar screen conveyor belt is disposed within the mounting frame and is arranged in a ring. The bar screen conveyor belt includes several bar screen plates that are rotatably connected end-to-end. The cleaning assembly is disposed inside the ring-shaped bar screen conveyor belt and includes a rotating box, a lifting plate, a rotating rod, and a cleaning toothed plate. A connecting box is connected to the inner side of the mounting frame, and a rotating sleeve rod is vertically rotatably connected to the connecting box. The bottom end of the rotating sleeve rod is connected to the top surface of the rotating box. The rotating box is a hollow circular box. Several first connecting holes are opened vertically on the peripheral wall of the rotating box. The lifting plate is horizontally arranged in the rotating box. Several rotating rods are arranged on the edge of the lifting plate. Several rotating rods are arranged in a one-to-one correspondence with several first connecting holes. One end of the rotating rod extends out of the rotating box through the corresponding first connecting hole. The cleaning toothed plate is arranged at the end of the rotating rod that extends out of the rotating box. The cleaning toothed plate contacts the inner side of the grid plate. The connecting box is provided with a driving component for driving the rotating sleeve rod to rotate.

[0006] By adopting the above technical solution, during the operation of the grid conveyor belt, the rotating sleeve rotates under the drive of the driving component, the rotating box rotates with the rotating sleeve, and several rotating rods rotate. The cleaning toothed plates set at the ends of the rotating rods hook off the impurities adhering to the inner side of the grid plate, thus cleaning the grid plate. Through the cooperation of the grid conveyor belt, the mounting frame, and the cleaning components, the surface impurities of the grid plate are cleaned, achieving the same effect as a bar screen cleaning machine.

[0007] Optionally, a lifting rod is coaxially arranged in the rotating sleeve rod. The lifting rod extends into the rotating box and is rotatably connected to the lifting plate. The lifting plate is a circular plate with a diameter smaller than the inner diameter of the rotating box. A driving component for driving the lifting rod to move vertically is provided in the connecting box. The first connecting hole is arranged along the axial direction of the rotating box. The rotating rod is slidably connected to the first connecting hole. A top support spring is provided in the first connecting hole. One end of the top support spring is connected to the inner bottom wall of the first connecting hole, and the other end abuts against the bottom surface of the rotating rod. In its natural state, the rotating rod is pressed against the inner top wall of the first connecting hole under the action of the top support spring.

[0008] By adopting the above technical solution, when the cleaning toothed plate needs to be cleaned, the lifting plate moves upward under the drive of the lifting rod. As the lifting plate moves, the rotating rod rotates downward under the limiting action of the first connecting hole. The cleaning toothed plate set at the end of the rotating rod separates from the grid plate, making it easier for the operator to remove the impurities hooked on the cleaning toothed plate.

[0009] Optionally, the rotating box is provided with a cutting assembly, which includes a cutting blade and a moving plate. The moving plate is a circular plate and is horizontally and coaxially arranged in the rotating box. Several cutting blades are vertically connected to the edge of the moving plate. Several second connecting holes are opened along the axial direction on the peripheral wall of the rotating box. Several cutting blades correspond one-to-one with several second connecting holes and are slidably connected. The rotating box is provided with a driving component for driving the moving plate to rise and fall. The edge of the cutting blade extends out of the rotating box.

[0010] By adopting the above technical solution, some filamentous impurities such as hair will become entangled on the peripheral wall of the rotating box as it rotates. At this time, the drive unit drives the moving plate to move back and forth in the vertical direction, and the cutting blade cuts the hair on the rotating box, making it easy to remove.

[0011] Optionally, a sealing plate is provided on the edge of the movable plate, and the cutting blade is connected to the side wall of the sealing plate away from the movable plate. The length of the sealing plate is greater than the length of the cutting blade. The sealing plate covers the second connecting hole. One side of the sealing plate is slidably attached to the inner peripheral wall of the rotating box. A connecting blind groove communicating with the first connecting hole is opened on the inner wall of the rotating box. A sealing rubber plate is embedded in the connecting blind groove. A sliding hole for the rotating rod to pass through is opened on the sealing rubber plate. The rotating rod is attached to the inner wall of the sliding hole.

[0012] By adopting the above technical solution, the sealing plate blocks the second connecting hole, and the sealing rubber plate blocks the first connecting hole, reducing the possibility of moisture from the external environment entering the rotating box and affecting its structure.

[0013] Optionally, the connecting box is provided with a mounting plate on the side near the inner wall of the mounting frame, and a mounting strip is vertically connected to the inner wall of the mounting frame. The mounting strip has a mounting groove along the vertical direction, the mounting plate is inserted into the mounting groove, and the mounting strip is provided with a connector for connecting the mounting plate.

[0014] By adopting the above technical solution, the mounting plate is inserted into the mounting groove, realizing the detachable connection between the connecting box and the mounting frame, which makes it convenient for operators to remove the cleaning components as a whole for device maintenance.

[0015] Optionally, the mounting strip has a plurality of alignment holes along its length, the mounting plate has mounting holes, the length of the mounting strip is greater than the length of the mounting plate, the mounting holes are connected to and correspond to one of the alignment holes, and the mounting holes and the corresponding alignment holes are provided with connecting bolts for connection.

[0016] By adopting the above technical solution, the mounting plate is slidably set in the mounting groove of the mounting strip. In actual operation, the height of the connecting box can be adjusted according to the usage requirements, thus expanding the applicability of the device.

[0017] Optionally, an inspection opening is provided on the side wall of the mounting frame, and an inspection door is detachably connected to the inspection opening.

[0018] By adopting the above technical solution, the installation of inspection openings and doors facilitates the maintenance of cleaning components by operators.

[0019] Optionally, the cleaning plate is made of an elastic material.

[0020] By adopting the above technical solution, since the cleaning toothed plate is made of elastic material, the possibility of damage to the grid plate during the cleaning process is reduced.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. Through the cooperation of the grid conveyor belt, the mounting frame and the cleaning components, the surface of the grid mesh is cleaned of impurities, achieving the same effect as a grid cleaning machine; 2. The cutting component design reduces the likelihood of hair getting tangled in the rotating box; 3. Because the cleaning toothed plate is made of elastic material, there is a possibility of damage to the grid plate during the cleaning process. Attached Figure Description

[0030] Reference Figure 2-4 The cleaning component 3 is housed within the mounting frame 2, inside the annular grid conveyor belt 1. The cleaning component 3 includes a rotating sleeve 31, a rotating box 32, a lifting plate 33, a lifting cylinder 34, a cleaning motor 35, a lifting rod 36, a rotating rod 37, and a cleaning toothed plate 38. A connecting box 16 is provided on the vertical inner wall of the mounting frame 2, and the cleaning motor 35 is connected to the connecting box 16. The output shaft of the cleaning motor 35 extends horizontally and is connected to a drive bevel gear 5. The rotating sleeve 31 is vertically positioned, with one end located in and rotatably connected to the connecting box 16. A driven bevel gear 6 is connected to the top of the rotating sleeve 31, meshing with the drive bevel gear 5. The rotating box 32 is a cylindrical hollow box, with the bottom end of the rotating sleeve 31 connected to the center of the top surface of the rotating box 32. The lifting plate 33 is a circular plate, and it is coaxially and horizontally arranged in the rotating box 32. The diameter of the lifting plate 33 is smaller than the inner diameter of the rotating box 32. Several rotating rods 37 are rotatably connected to the edge of the lifting plate 33, and the rotation plane of the rotating rods 37 is vertical.

[0031] Reference Figure 3 and Figure 4 A plurality of first connecting holes 321 are formed along the axial direction on the peripheral wall of the rotating box 32. A plurality of rotating rods 37 are arranged corresponding to the plurality of first connecting holes 321, and the rotating rods 37 are slidably disposed in the corresponding first connecting holes 321. A top support spring 7 is provided in the first connecting hole 321. The bottom end of the top support spring 7 is connected to the inner bottom wall of the first connecting hole 321, and the top end of the top support spring 7 is connected to a top support block 8. The top support block 8 slides in the first connecting hole 321 and abuts against the bottom surface of the rotating rod 37. In the natural state, the rotating rod 37 abuts against the inner top wall of the first connecting hole 321 under the action of the top support spring 7. A cleaning toothed plate 38 is connected to the end of the rotating rod 37 away from the lifting plate 33. The cleaning toothed plate 38 is made of elastic material. When the rotating rod 37 rotates to the horizontal state, the cleaning toothed plate 38 contacts the inner wall of the grid plate 101.

[0032] Reference Figure 3 and Figure 4The inner ring wall of the rotating box 32 is provided with several connecting blind grooves 323, which are respectively arranged in a corresponding manner with several first connecting holes 321. A sealing rubber plate 10 is embedded in the connecting blind groove 323. A sliding hole 11 for the rotating rod 37 to pass through is provided on the sealing rubber plate 10. The inner wall of the sliding hole 11 is fitted to the rotating rod 37. The lifting cylinder 34 is arranged in the connecting box 16. The output shaft of the lifting cylinder 34 extends vertically downward and is connected to a vertically arranged lifting rod 36. The lifting rod 36 is coaxially arranged in the rotating sleeve 31. The bottom end of the lifting rod 36 extends into the rotating box 32 and is rotatably connected to the center position of the lifting plate 33.

[0033] Reference Figure 2-4 The cutting assembly 4 is mounted on the rotating box 32 and includes a cutting blade 41, a moving plate 42, a sealing plate 43, a drive motor 44, a drive cam 45, and a return spring 46. The moving plate 42 is a circular plate, coaxially and horizontally positioned within the rotating box 32. Several sealing plates 43 are connected to the edge of the moving plate 42. The sealing plates 43 are arc-shaped, with their outer arc walls slidably fitting against the inner ring wall of the rotating box 32. One cutting blade 41 is vertically connected to the outer arc wall of each sealing plate 43, and the cutting blade 41 is positioned along the radius of the rotating box 32. Several second connecting holes 322 are formed on the peripheral wall of the rotating box 32. The length of each second connecting hole 322 is greater than the length of the cutting blade 41. Each cutting blade 41 corresponds to and is slidably connected to one of the second connecting holes 322. The edges of the cutting blades 41 extend out of the rotating box 32 through the second connecting holes 322, and the sealing plates 43 seal the second connecting holes 322. A return spring 46 is located on the moving plate 42 below the lifting plate 33. Several springs connect the bottom surface of the moving plate 42 to the inner bottom wall of the rotating box 32. A drive motor 44 is located on the inner bottom wall of the rotating box 32. The output shaft of the drive motor 44 is horizontally positioned and connected to the drive cam 45. In its natural state, the moving plate 42 abuts against the side of the drive cam 45 under the action of the return spring 46.

[0034] Reference Figure 1 , Figure 2 and Figure 5Two mounting strips 9 are vertically connected to the inner wall of the mounting frame 2. Each mounting strip 9 has a mounting groove 91 on its vertical side where they are close to each other. A mounting plate 12 is provided on each of the opposite edges of the connecting box 16. The length of the mounting plate 12 is less than the length of the mounting strip 9. The mounting plate 12 has mounting holes 121, and the mounting strip 9 has alignment holes 92 communicating with the mounting grooves 91. Several alignment holes 92 are evenly spaced along the vertical direction on the mounting strip 9. The two mounting plates 12 correspond one-to-one with the two mounting strips 9, and the mounting plates 12 are slidably inserted into the corresponding mounting grooves 91 of the mounting strip 9. The mounting holes 121 and the alignment holes 92 on the mounting strip 9 are positioned correspondingly, and both are connected by connecting bolts 13 for connecting the mounting plates 12 and the mounting strips 9. The mounting frame 2 has an inspection opening 14 for easy maintenance by operators. An inspection door 15 is detachably connected to the inspection opening 14 via a connector.

[0035] Reference Figure 2-4 When cleaning impurities entangled on the grid plate 101, the cleaning motor 35 starts, driving the drive bevel gear 5 to rotate. The drive bevel gear 5 drives the driven bevel gear 6 to rotate, causing the rotating sleeve rod 31 to rotate. This causes the rotating box 32 connected to the rotating sleeve rod 31 to rotate. The lifting plate 33 and several rotating rods 37 connected to the lifting rod 36 rotate synchronously. The cleaning toothed plates 38 located at the ends of the rotating rods 37 hook off hair and other impurities entangled on the inner side of the grid plate 101, thus cleaning the inner side of the grid plate. Because the cleaning toothed plates 38 are made of elastic material, the possibility of damage to the grid plate 101 during the cleaning process is reduced.

[0036] Reference Figure 2-4 When it is necessary to clean the impurities hooked on the cleaning toothed plate 38, the operator opens the inspection door 15 when the water flow stops. The lifting cylinder 34 drives the lifting rod 36 to move upward, and the lifting plate 33 moves upward accordingly. Several rotating rods 37 rotate downward under the action of the lifting plate 33 and the limiting action of the first connecting hole 321. The cleaning toothed plate 38 set at the end of the rotating rod 37 separates from the inner side of the grid plate 101, making it easier for the operator to remove the impurities wrapped around it.

[0037] Reference Figure 4As the rotating box 32 rotates, some hair will become entangled on it. At this time, the drive motor 44 starts and drives the drive cam 45 to rotate. Under the drive of the drive cam 45, the moving plate 42 moves back and forth in the vertical direction, driving the cutting blade 41 to move back and forth in the second connecting hole 322. The cutting blade 41 cuts the filamentous impurities entangled on the outside of the rotating box 32, making it easy for the operator to remove them. The sealing plate 43 seals the second connecting hole 322, and the sealing rubber plate 10 seals the first connecting hole 321, reducing the possibility of external water entering the rotating box 32 and affecting the internal structure.

[0038] Reference Figure 2 and Figure 5 The mounting plate 12 and mounting strip 9 enable a detachable connection between the connecting box 16 and the mounting frame 2, facilitating the removal of the cleaning component 3 for maintenance. Since the length of the mounting strip 9 is greater than that of the mounting plate 12, and several alignment holes 92 are provided on the mounting strip 9, it allows operators to adjust the installation height of the connecting box 16 according to actual needs, thus expanding the applicability of the device.

[0039] The implementation principle of the internal flow bar screen cleaner with easy fiber removal in this embodiment is as follows: When cleaning impurities wrapped around the bar screen 101, the cleaning motor 35 starts, and the cleaning toothed plate 38 hooks off hair and other impurities wrapped around the inside of the bar screen 101, thus cleaning the inside of the bar screen. When it is necessary to clean the impurities hooked on the cleaning toothed plate 38, the lifting rod 36 moves upward, and several rotating rods 37 rotate downward, separating the cleaning toothed plate 38 from the inside of the bar screen 101, making it easier for the operator to remove the impurities wrapped around it.

[0040] The drive motor 44 starts, driving the cutting blade 41 to reciprocate in the second connecting hole 322. The cutting blade 41 cuts the filamentous impurities wrapped around the outside of the rotating box 32, making it easy for the operator to remove them. The mounting plate 12 and the mounting strip 9 enable a detachable connection between the connecting box 16 and the mounting frame 2, making it easy for the operator to remove the cleaning assembly 3 as a whole for maintenance.

[0041] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
