Technical Field

[0001] This utility model relates to the field of rotary drum filter technology, and in particular to an automatic cleaning rotary drum filter structure. Background Technology

[0002] Rotary drum filters achieve continuous solid-liquid separation through the mechanical structure of a rotating drum-shaped filter screen, making them an indispensable filtration device in industrial production. The drum is the core component of the rotary drum filter, typically a horizontally placed cylindrical structure made of rolled and welded stainless steel plates or similar materials. The drum wall has evenly spaced perforations, and a support plate and filter cloth are laid on the drum surface to form the filter surface. The space beneath the filter surface is divided into several separate sector-shaped filter chambers, each connected to a distribution valve via a conduit.

[0003] Existing rotary drum filters are inconvenient to automatically clean during use, which leads to clogging of the filter holes on the drum, affecting the efficiency and quality of solid-liquid separation. Utility Model Content

[0004] The purpose of this invention is to provide an automatic cleaning drum filter structure to solve the problem that existing drum filters are inconvenient to automatically clean the drum.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an automatic cleaning drum filter structure, including a filter box;

[0006] A water inlet pipe is fixedly connected to one side of the filter box, a drain pipe is fixedly connected to the other side of the filter box, a water tank is fixedly connected to the outer wall of the filter box, and a cleaning mechanism is fixedly connected to the outer wall of the filter box.

[0007] The cleaning mechanism includes a support plate fixedly installed on the top of the filter box. A drive motor is fixedly connected to the outer wall of the support plate. The output shaft of the drive motor is fixedly connected to a first rotating rod through a coupling. A first gear is fixedly connected to the outer wall of the first rotating rod, and a second gear is movably connected to the outer wall of the first gear.

[0008] Preferably, a second rotating rod is fixedly connected to the inner wall of the second gear, and a housing is movably connected to the outer wall of the second rotating rod. A water pumping pipe is fixedly connected to one side of the housing, and a water supply pipe is fixedly connected to the other side of the housing. A diverter plate is fixedly connected to the output end of the water supply pipe, and a nozzle is installed on the outer wall of the diverter plate.

[0009] Preferably, the first gear forms a rotating structure with the outer casing through the first rotating rod, and the first gear meshes with the second gear, so that the rotation of the first gear can drive the rotation of the second gear.

[0010] Preferably, the second gear forms a rotating structure with the outer casing via the second rotating rod, and the input end of the water pumping pipe is connected to the water tank, which can pump water from the water tank into the outer casing through the water pumping pipe.

[0011] Preferably, a filtering mechanism is installed on the outer wall of the first rotating rod. The filtering mechanism includes a first transmission wheel fixedly installed on the outer wall of the first rotating rod. A transmission belt is movably connected to the outer wall of the first transmission wheel. A second transmission wheel is movably connected to the inner wall of the transmission belt. A rotating shaft is fixedly connected to the inner wall of the second transmission wheel. A drum body is fixedly connected to one end of the rotating shaft.

[0012] Preferably, the first drive wheel is engaged with the drive belt, and the drive belt is engaged with the second drive wheel, so that the rotation of the first drive wheel can drive the rotation of the second drive wheel.

[0013] Preferably, the main body of the drum forms a rotating structure with the filter box via a rotating shaft, the second transmission wheel forms a rotating structure with the filter box via a rotating shaft, the rotating shaft forms a rotating structure with the water inlet pipe, and the first transmission wheel and the second transmission wheel are arranged in parallel, so that the main body of the drum can rotate and filter the sewage.

[0014] The automatic cleaning drum filter structure provided by this utility model has the following advantages:

[0015] The system consists of a water tank, a cleaning mechanism, a diverter plate, nozzles, and a rotating drum body. By starting the drive motor, the first gear can rotate, and the second gear can rotate along the outer shell. Water from the water tank can be drawn into the outer shell through the water pumping pipe and output through the water delivery pipe. Multiple nozzles spray and wash the rotating drum body, thus facilitating automatic cleaning of the rotating drum body.

[0016] Furthermore, since the nozzles are evenly distributed on the outer wall of the diverter plate, the spraying range can be increased;

[0017] The first rotating rod, nozzle, and filter mechanism are designed to rotate the first transmission wheel, which in turn drives the second transmission wheel to rotate under the action of the transmission belt. This causes the main body of the drum, which is fixedly connected to the outer wall of the rotating shaft, to rotate, thus facilitating the filtration of wastewater.

[0018] Furthermore, since the rotating shaft and the inlet pipe form a rotating structure, the rotating filtration of the drum body and the injection of sewage through the inlet pipe can be separated without interference.

[0019] Furthermore, since the rotation of the drum body is synchronized with the water spraying from the nozzle, the drum body can be cleaned by the water jet from the nozzle while it is rotating and filtering. Attached Figure Description

[0026] 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.

[0027] Please see Figures 1-5 The present invention provides an automatic cleaning drum filter structure, including a filter box 1.

[0028] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, a water inlet pipe 2 is fixedly connected to one side of the filter box 1, and a drain pipe 3 is fixedly connected to the other side of the filter box 1. A water tank 4 is fixedly connected to the outer wall of the filter box 1, and a cleaning mechanism 5 is fixedly connected to the outer wall of the filter box 1. The cleaning mechanism 5 includes a support plate 51 fixedly installed on the top of the filter box 1. A drive motor 52 is fixedly connected to the outer wall of the support plate 51. The output shaft of the drive motor 52 is fixedly connected to a first rotating rod 53 via a coupling. A first gear 54 is fixedly connected to the outer wall of the first rotating rod 53, and a second gear 55 is movably connected to the outer wall of the first gear 54. A second rotating rod 56 is fixedly connected to the inner wall of the water tank 5. A housing 57 is movably connected to the outer wall of the second rotating rod 56. A water pumping pipe 58 is fixedly connected to one side of the housing 57, and a water supply pipe 59 is fixedly connected to the other side of the housing 57. A diverter plate 6 is fixedly connected to the output end of the water supply pipe 59. A nozzle 7 is installed on the outer wall of the diverter plate 6. A first gear 54 forms a rotating structure with the housing 57 through a first rotating rod 53. The first gear 54 is meshed with a second gear 55. The second gear 55 forms a rotating structure with the housing 57 through a second rotating rod 56. The input end of the water pumping pipe 58 is connected to the water tank 4.

[0029] By starting the drive motor 52, the first gear 54, which is fixedly connected to the outer wall of the first rotating rod 53, can rotate. Since the first gear 54 is meshed with the second gear 55, the second gear 55 can rotate along the outer shell 57 under the action of the second rotating rod 56. Since the first gear 54 and the second gear 55 rotate in opposite directions, water in the water tank 4 can be drawn into the outer shell 57 through the water pumping pipe 58 and output through the water supply pipe 59, so that the water can be sprayed out through the nozzles 7 installed at the bottom of the diverter plate 6, so that multiple nozzles 7 can automatically spray and wash the rotating drum body 85.

[0030] Reference Figure 3 and Figure 4 As shown, a filter mechanism 8 is installed on the outer wall of the first rotating rod 53. The filter mechanism 8 includes a first transmission wheel 81 fixedly installed on the outer wall of the first rotating rod 53. A transmission belt 82 is movably connected to the outer wall of the first transmission wheel 81. A second transmission wheel 83 is movably connected to the inner wall of the transmission belt 82. A rotating shaft 84 is fixedly connected to the inner wall of the second transmission wheel 83. A drum body 85 is fixedly connected to one end of the rotating shaft 84. The first transmission wheel 81 is meshed with the transmission belt 82, and the transmission belt 82 is meshed with the second transmission wheel 83. The drum body 85 and the filter box 1 form a rotating structure through the rotating shaft 84. The second transmission wheel 83 and the filter box 1 form a rotating structure through the rotating shaft 84. The rotating shaft 84 and the water inlet pipe 2 form a rotating structure. The first transmission wheel 81 and the second transmission wheel 83 are arranged in parallel.

[0031] By injecting wastewater into the drum body 85 through the inlet pipe 2, the first drive wheel 81 is rotated by the rotation of the first rotating rod 53. Since the first drive wheel 81 is meshed with the drive belt 82 and the drive belt 82 is meshed with the second drive wheel 83, the second drive wheel 83 can be rotated, causing the drum body 85, which is fixedly connected to the outer wall of the rotating shaft 84, to rotate. This allows water to flow out through the filter holes of the drum body 85, achieving solid-liquid separation. The filtered water is then discharged through the drain pipe 3.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
