[0004] While existing screen plate bar cleaning machines achieve the advantages of thorough rinsing and good decontamination, they still have some shortcomings: existing screen plate bar cleaning machines can only clean the bar conveyor belt, but cannot clean the bar below. This causes hair, soft metal wires, and plastic fibers in the sewage to easily get tangled on the bar and cannot be cleaned by the rake teeth. Secondly, when the rake teeth move to the top of the frame, the fixed dirt on the rake teeth may get tangled on the rake teeth and cannot fall off by its own weight, thus being carried back into the sewage below, resulting in poor cleaning effect. Utility Model Content
[0005] To overcome the shortcomings of the existing technology, a screen plate bar screen cleaning machine is provided to solve the problems mentioned in the background.
[0006] To achieve the above objectives, a screen-type bar screen cleaning machine is provided, comprising: a frame, a drive device on the upper side of the frame, a traction belt chain on the inner side of the frame, and rake teeth connected to the inner side of the traction belt chain; a bar screen is provided on the rear side of the rake teeth, and a slag-collecting plate is connected to the upper side of the bar screen; a release mechanism is provided on the upper side of the frame, and the release mechanism includes an air pump, and an air nozzle is connected to the lower side of the air pump; an upper groove plate is movably connected to the upper end of the bar screen, and a lower groove plate is movably connected to the lower end of the bar screen; a cleaning component is provided on the rear side of the bar screen, and the cleaning component includes a collection groove and a guide groove formed on both side walls of the frame, and a cleaning component is provided inside the collection groove.

[0022] 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.
[0023] Reference Figures 1 to 5As shown, this utility model provides a screen-type bar screen cleaning machine, including: a frame 1, a drive device 2 on the upper side of the frame 1, a traction chain 3 on the inner side of the frame 1, and rake teeth 4 connected to the inner side of the traction chain 3. A grid bar 6 is provided behind the rake teeth 4, and a slag-collecting plate 7 is connected to the upper side of the grid bar 6. The drive device 2 is connected to the upper end of the traction chain 3, and the rake teeth 4 are fixed at equal intervals on the traction chain 3. A release mechanism 5 is provided on the upper side of the frame 1, and the release mechanism 5 includes an air pump 51, with an air nozzle 53 connected to the lower side of the air pump 51. The grid bar... The upper end of the 6 is movably connected to the upper groove plate 8, and the lower end of the grid bar 6 is movably connected to the lower groove plate 10. A cleaning component 9 is provided on the rear side of the grid bar 6. The cleaning component 9 includes a storage groove 91 and a guide groove 92 opened on both sides of the frame 1. A cleaning component 93 is provided inside the storage groove 91. The cleaning component 93 includes a shaft 931. A cleaning clamping rod 934 is connected to the outer wall of the shaft 931. A handle rod 932 is connected to both ends of the shaft 931. The shaft 931 is slidably connected in the storage groove 91. A second locking nut 933 is screwed to the outside of the handle rod 932.
[0024] In this embodiment, the frame 1, drive device 2, traction belt chain 3, rake teeth 4, grid bar 6 and slag tray 7, as well as the detachment mechanism 5 and cleaning assembly 9 constitute the main structure of the screen plate bar screen cleaning machine involved in this application.
[0025] Among them, the frame 1, drive equipment 2, traction belt chain 3, rake teeth 4, grid bar 6 and slag tray 7 are set as the basic structure of the screen plate bar screen cleaning machine under the existing technology.
[0026] Specifically, the rake teeth 4 rotate counterclockwise with the traction belt chain 3, and the rake teeth 4 scrape and clean the solid dirt trapped by the grid bars 6 through the gaps in the grid bars 6.
[0027] Specifically, when not in use, the cleaning component 93 causes the handle rod 932 on the outside of the shaft 931 to be placed outside the guide groove 92 and then fixed by the second locking nut 933.
[0028] The cleaning clamp 934 has triangular scrapers on both sides and is made of elastic metal. When the cleaning clamp 934 is inserted into the grid bar 6, it maintains an elastic clamping force with the grid bar 6, making it easy to scrape off the hair, metal wires and plastic fibers wrapped on the grid bar 6 downwards.
[0029] like Figures 1 to 4In the middle, the air pump 51 is connected to the lower side of the air outlet pipe 52, and the air outlet pipe 52 is fixed to the inner wall of the frame 1 by the fixing rod 54. The air nozzle 53 is connected to the lower side of the air outlet pipe 52 at equal intervals. The upper slot plate 8 has a clearance groove 81 inside, and the two side walls of the upper slot plate 8 have limit grooves 82. The upper end of the grid bar 6 is connected to the through rod 61, and the two ends of the through rod 61 are provided with threaded sections 62. The threaded sections 62 are slidably connected in the limit grooves 82. At the same time, the outer side of the threaded section 62 is screwed with a first locking nut 63. The upper side of the lower slot plate 10 is provided with a positioning groove, and the lower end of the grid bar 6 is matched and inserted into the positioning groove.
[0030] Specifically, the air nozzle 53 is tilted, and when the air nozzle 53 blows towards the rake tooth 4, the rake tooth 4 is tilted downwards. During the process of the dirt falling down on the rake tooth 4, it is blown by the high-pressure gas.
[0031] Specifically, the upper groove plate 8 is fixedly mounted against the side wall of the frame 1, and the limiting groove 82 extends to the outer wall of the frame 1. At this time, the grid bar 6 is fixed by the first locking nut 63 and the threaded section 62.
[0032] When in use, the equipment is installed in the sewage tank, with the screen bars placed in the sewage. When the drive is started, the sewage flows through the screen bars, trapping the debris. Then, the debris is lifted to the surface by the rake teeth and discharged through the drain port on the upper side of the frame.
[0033] The detachment mechanism, comprising an air pump, air pipe, air nozzle, and fixing rod, allows air to be sprayed onto the rake teeth as they rotate to the top of the traction chain, facilitating the removal of solid waste and preventing it from becoming entangled and unable to detach under its own weight. When cleaning the grid bars, the shaft is detached from the collection slot by holding the handle. The cleaning clamp at the front of the shaft holds the outside of the grid bar. The shaft is then manually moved downwards via the guide slot, pushing the dirt entangled on the outside of the grid bar downwards to the bottom. The grid bar is then manually moved upwards via the clearance slot and through rod, causing the bottom of the grid bar to detach from the lower slot plate, allowing solid waste to easily detach from the bottom of the grid bar, thus achieving a convenient cleaning effect.
[0034] The screen plate bar screen cleaner of this utility model can effectively solve the problems mentioned in the background technology. Based on the existing screen plate bar screen cleaner technology, it can improve the separation effect of rake teeth from dirt and also has the effect of cleaning the bar screen.
[0035] 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 claims and their equivalents.
