Description

Technical Field

[0001] This utility model relates to the field of bar screen cleaning technology, specifically a rotary bar screen cleaning machine. Background Technology

[0002] Rotary bar screens are specialized water treatment equipment that can continuously and automatically intercept and remove debris of various shapes from fluids. They are widely used in urban wastewater treatment. With a compact structure, they mainly consist of a drive unit, frame, sprockets, chain, rake teeth, and cleaning device. Through continuous rotation, the rake teeth effectively trap and remove larger solid impurities from wastewater, ensuring the smooth operation of subsequent treatment equipment.

[0003] However, existing bar screens, after dumping solid impurities into the recycling bin using rake teeth, suffer from the lack of a protective mechanism on the top of the bin, allowing some impurities from the wastewater to fall outside. Over time, this can negatively impact the environment. Furthermore, some silt and wastewater remain in the recycling bin, and the lack of a screening mechanism hinders the proper sorting and cleaning of other solid waste and debris. Therefore, to address these issues, we need to design a rotary bar screen. Utility Model Content

[0010] In a preferred embodiment of the rotary bar screen cleaner described in this utility model, the filter assembly includes a draw plate, a filter screen plate, a side plate, a first spring, and a protrusion. The draw plate is provided with a movable groove, the protrusion is fixedly connected to both sides of the draw plate, the side plate is fixedly connected to both sides of the filter screen plate, one end of the first spring is fixedly connected to the side plate, and the other end of the first spring is fixedly connected to the inner wall of the movable groove. The filter screen plate is slidably connected in the movable groove, and the draw plate is slidably connected in the filter groove.

[0011] In a preferred embodiment of the rotary bar screen cleaner described in this utility model, the striking assembly includes a timing belt, a timing pulley, a striking rod, and a striking block.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: When using this device, solid impurities in sewage can be filtered through the connecting belt with through holes on the dirt removal component, leaving solid impurities on the connecting belt. When the motor drives the rotating roller on one side to rotate, it drives the sprocket to rotate. Since the sprocket and chain mesh, the connecting belt can move with the chain, and the rake teeth on the connecting belt can transport the filtered solid impurities to the filter component for collection. When solid impurities fall onto the filter screen plate, the side plate can prevent the transported solid impurities from falling to the outside. Furthermore, the inclined plate set at the top of the inner tank of the machine can further protect the solid impurities from falling to the outside of the filter component, which would affect the recovery of solid impurities. At the same time, when the motor is working, the rotating roller will drive the striking component to rotate, so that the striking block strikes the filter component from below, which can cause the solid impurities on the filter component to vibrate, thereby filtering smaller solid particles into the collection component, which is convenient for screening impurities in sewage and facilitating subsequent treatment.

Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] Please see Figures 1-6 This utility model provides a rotary bar screen cleaning machine, comprising:

[0026] The machine body 101 is equipped with a dirt removal component 110, a filter component 120, a tapping component 130, and a collection component 140.

[0027] Specifically, the dirt removal component 110 can filter solid impurities in the wastewater and transport the filtered solid impurities to the filter component 120 for collection. At the same time, when the dirt removal component 110 is transporting solid impurities, it will drive the striking component 130 to strike the filter component 120 from below. This will cause the solid impurities on the filter component 120 to vibrate, thereby filtering smaller solid particles into the collection component 140, which facilitates the screening of impurities in the wastewater and makes subsequent treatment easier.

[0028] Please see Figures 1-4A control panel 101a is fixedly connected to one side of the body 101. A filter tank 101b is provided in the inner groove of the body 101. A rotating groove 101c is provided in the inner groove of the body 101. A placement groove 101d is provided in the inner groove of the body 101. A fixing groove 101e is provided in the placement groove 101d. An inclined plate 101f is fixedly connected to the top of the inner groove of the body 101. The cleaning assembly 110 includes a motor 110a, a rotating roller 110b, a sprocket 110c, a chain 110d, a connecting belt 110e, and rake teeth 110f. A pair of chains 110d are fixedly connected to both sides of the connecting belt 110e. The sprocket 110c meshes with the inner groove of the chain 110d. The rotating roller 110b is fixedly connected to the sprocket 110c. The motor 110a is fixedly connected to one side of the machine body 101. One rotating roller 110b is fixedly connected to the power output end of the motor 110a. The rake teeth 110f are fixedly connected to the connecting belt 110e.

[0029] Specifically, the device can be controlled via the control panel 101a, facilitating operation by staff. When the device is working, wastewater is discharged through the through-holes in the connecting belt 110e, and solid impurities in the wastewater are filtered onto the connecting belt 110e. When the motor 110a operates, the rotating roller 110b rotates within the machine body 101, causing the roller 110b to drive the sprocket 110c to rotate. Since the sprocket 110c meshes with the chain 110d, the chain 110d drives the connecting belt 110e to move. The rake teeth 110f on the connecting belt 110e drive the solid impurities on the connecting belt 110e to move to the filter assembly 120 in the inner tank of the machine body 101 for filtration and screening. Furthermore, the inclined plate 101f at the top of the inner tank of the machine body 101 prevents some impurities from falling outside the device when the rake teeth 110f drive the solid impurities into the filter assembly 120, which would have an adverse impact on the environment and require workers to clean them, which is time-consuming and labor-intensive.

[0030] Please see Figures 1-5The filter assembly 120 includes a drawer plate 120a, a filter screen plate 120b, a side plate 120c, a first spring 120d, and a protrusion 120e. The drawer plate 120a is provided with a movable groove 120f. The protrusion 120e is fixedly connected to both sides of the drawer plate 120a. The side plate 120c is fixedly connected to both sides of the filter screen plate 120b. One end of the first spring 120d is fixedly connected to the side plate 120c, and the other end of the first spring 120d is fixedly connected to the inner wall of the movable groove 120f. The filter screen plate 120b is slidably connected in the movable groove 120f, and the drawer plate 120a is slidably connected in the filter tank 101b. The striking assembly 130 includes a timing belt 130a, a timing pulley 130b, a striking rod 130c, and a striking block 130d. One timing pulley 130b is fixedly connected to the rotating roller 110b, and the other timing pulley 130b is fixedly connected to one side of the striking rod 130c. The timing pulley 130b meshes with the internal teeth of the timing belt 130a. The striking block 130d is fixedly connected to the striking rod 130c, and the striking rod 130c is rotatably connected to the rotating groove 101c. A protective cover 120g is fixedly connected to the filter screen plate 120b, and a baffle 120h is fixedly connected to the bottom of the filter screen plate 120b.

[0031] Specifically, when solid impurities fall onto the filter screen plate 120b, the motor 110a drives the rotating roller 110b to rotate. One synchronous pulley 130b is fixedly connected to the rotating roller 110b, and another synchronous pulley 130b is fixedly connected to one side of the striking rod 130c. The synchronous pulley 130b meshes with the internal teeth of the synchronous belt 130a, causing the striking rod 130c to drive the striking block 130d to strike the bottom of the filter screen plate 120b, facilitating the filtration of sediment and other solid impurities into the collection component 140, thus enabling the device to screen the solid impurities. When the striking block 140d strikes the filter screen plate 120b, the force of the first spring 120d... This allows the filter screen plate 120b to move up and down in the movable groove 120f, facilitating the filtration and sieving of solid impurities. Furthermore, by installing a baffle 120h at the bottom of the filter screen plate 120b, some solid impurities can be prevented from falling to the bottom of the movable groove 120f when the filter screen plate 120b vibrates up and down in the movable groove 120f, thus affecting the normal operation of the filter screen plate 120b. At the same time, by installing a protective cover 120g on the top of the filter screen plate 120b, the device can easily collect solid impurities, preventing them from falling off the filter screen plate 120b and falling outside the device, which would require time-consuming and labor-intensive cleaning by personnel.

[0032] Please see Figures 1-6The collection component 140 includes a recycling bin 140a, a protective plate 140b, a limiting plate 140c, a protrusion 140d, and a second spring 140e. The limiting plate 140c is fixedly connected to both sides of the recycling bin 140a. The protective plate 140b is fixedly connected to the recycling bin 140a. A circular groove 140f is provided on the upper limit plate 140c. One end of the second spring 140e is fixedly connected to the protrusion 140d, and the other end of the second spring 140e is fixedly connected to the inner wall of the circular groove 140f. The limiting plate 140c is slidably connected in the placement groove 101d.

[0033] Specifically, when the filter assembly 120 filters out solid impurities such as mud and sand into the recycling bin 140a, the protective plate 140b prevents them from splashing onto the outside of the recycling bin 140a, thus avoiding the need for cleaning by staff. Furthermore, when the device finishes decontamination, the staff pulls the recycling bin 140a, causing the limiting plates 140c on both sides of the recycling bin 140a to move in the placement groove 101d. This causes the protrusion 140d to retract into the circular groove 140f, and the second spring 140e to compress, allowing the protrusion 140d to leave the fixed groove 101e. This allows the recycling bin 140a to be pulled out of the placement groove 101d for replacement and cleaning.

[0034] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
