Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary equipment for cleaning and drying machines, specifically relating to a circulating filtration system for a cleaning and drying machine. Background Technology

[0002] Cleaning and drying machines are frequently used in the post-processing stage of parts manufacturing to remove grease, dirt, and other contaminants from the surfaces of parts. Specifically, conventional cleaning and drying machines often employ chain drive to transport workpieces and are continuous cleaning equipment with functions such as degreasing, washing, and drying. During operation, workpieces are manually placed on a specially designed transmission chain. During operation, the workpieces are placed on a conveyor belt and sequentially pass through a cleaning chamber, a high-pressure water-cutting chamber, and a hot air drying chamber, completing the cleaning and hot air drying processes before being discharged. This completes the cleaning of the parts, which can then proceed to the packaging stage. During the cleaning process, the clean water carries away dirt and residue from the surface of the parts, creating wastewater. To achieve a certain degree of recycling and reduce the cost of cleaning water, our company intends to develop a circulating filtration system to filter and recycle this wastewater. Summary of the Invention

[0003] The purpose of this invention is to provide a circulating filtration system for a cleaning and drying machine, which aims to solve the problem of circulating wastewater after cleaning in the cleaning and drying machine.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows:

[0005] A circulating filtration system for a cleaning and drying machine includes a first sewage pump A, a sedimentation tank, a second sewage pump B, a filtration device, and a clean water pump C.

[0006] The filtration device includes a base, a water collection tank, a filter barrel, and a drive assembly. The filter barrel is horizontally and movably mounted on the base, and the water collection tank is located below the filter barrel. Wastewater from the washing and drying machine is pumped to a sedimentation tank by a first wastewater pump A, and a second wastewater pump B pumps the wastewater from the sedimentation tank to the inlet of the drive assembly, so as to drive the filter barrel to rotate using the impact force of the water. The inlet of the purified water pump C is connected to the water collection tank. The device also includes a backwashing assembly, which includes a flushing pipe and a waste residue tank. The flushing pipe is located close to the outer side of the filter barrel and is arranged along the length of the filter barrel. The waste residue tank is located inside the filter barrel and directly below the flushing pipe. The waste residue tank is discharged through the waste residue pipe.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the drive assembly includes at least one backflush pipe; the inner circumferential surface of the filter bucket near the end where the backflush pipe is located is radially and evenly distributed with blades, the outlet of the backflush pipe faces the blades, and the outlet of the second sewage pump B is connected to the inlet end of the backflush pipe.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: two backwash pipes are provided, and the outlet of each backwash pipe is inclined towards the inside of the filter bucket.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: it further includes an annular baffle plate, which blocks the blades from facing the outer end of the filter barrel.

[0010] Based on the above scheme and as a preferred embodiment of the above scheme: the drive assembly includes a hydraulic turbine, the output shaft of the hydraulic turbine meshes with the outer circumferential surface of the filter barrel for transmission; the outlet of the second sewage pump B is connected to the inlet of the hydraulic turbine; blades are radially evenly distributed on the inner circumferential surface of the filter barrel near the end where the backwash pipe is located, and the outlet of the hydraulic turbine faces the blades.

[0011] Based on the above scheme and as a preferred embodiment of the above scheme: the outlet of the water purifier pump C is connected to the cleaning water inlet of the cleaning agent dryer, and is connected to the inlet of the rinsing pipe through a flow regulating valve.

[0012] Based on the above scheme and as a preferred embodiment of the above scheme: two sedimentation tanks are connected in series; the first sewage pump A is connected to the preceding sedimentation tank, and the second sewage pump B is connected to the following sedimentation tank.

[0013] The significant and beneficial technical effects of this invention compared to existing technologies are as follows: First sewage pump A pumps the collected sewage after cleaning to a sedimentation tank. After sedimentation for a certain period, second sewage pump B pumps the supernatant clear liquid to a filtration device. The pumped water flow drives the filter barrel to rotate, further filtering out suspended impurities in the clear liquid. In conjunction with the backwashing assembly, the filter screen of the filter barrel is backwashed. The residue after backwashing falls into a waste residue trough with the backwash water and is discharged through a slag discharge pipe into a collection tank for centralized treatment. Of course, the backwash water comes from a portion of the purified water pump C. The flushing force of the backwash water is adjusted by a flow regulating valve to meet the flushing requirements without affecting the water supply to the cleaning and drying machine.

[0020] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the given embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] In the description of this application, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0022] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Example 1

[0023] See details Figure 1-3 As shown, this application discloses a circulating filtration system for a washing and drying machine, including a first wastewater pump A, a sedimentation tank 60, a second wastewater pump B, a filtration device, and a purified water pump C. The filtration device includes a base 10, a water collection tank 20, a filter barrel 30, and a drive assembly 40. The filter barrel 30 is horizontally and movably mounted on the base 10, and the water collection tank 20 is located below the filter barrel 30. Wastewater from the washing and drying machine is pumped by the first wastewater pump A to the sedimentation tank 60, where sedimentation occurs to remove some solid particles. Subsequently, the second wastewater pump B pumps the upper clear liquid from the sedimentation tank 60 to the inlet of the drive assembly 40, using the impact force of the water to drive the filter barrel 30 to rotate. Specifically, see... Figure 2-3As shown, the drive assembly 40 includes at least one backflush pipe 44; blades 32 are radially evenly distributed on the inner circumferential surface of the filter barrel 30 near the end where the backflush pipe 44 is located, and the outlet of the backflush pipe 44 faces the blades 32. The outlet of the second sewage pump B is connected to the inlet end of the backflush pipe 44. Furthermore, to achieve a more even distribution of driving force, it is preferable to have two backflush pipes 44, which allow sewage to smoothly enter the filter barrel 30 while driving it to rotate. Preferably, the outlet of each backflush pipe 44 is inclined inwards towards the filter barrel 30. In addition, an annular baffle 33 is included, which blocks the blades 32 from the outer end of the filter barrel 30, effectively preventing sewage from splashing outwards. Thus, the flow of sewage impacts the blades 32, driving the filter barrel 30 to rotate. This allows more filter screens to participate in filtration, improving filtration efficiency. Directly using water flow to drive the filter barrel 30 is more energy-efficient than using a separate motor to drive the filter barrel, and also reduces equipment costs.

[0024] Wastewater is filtered through the filter screen on the filter barrel 30, removing suspended residues and collecting in the water collection tank 20. The inlet of the water purification pump C is connected to the water collection tank 20, allowing the filtered clean water in the water collection tank 20 to be pumped into the cleaning water tank of the cleaning and drying machine (it should be noted that the clean water here meets the water quality requirements for cleaning by the cleaning machine). Of course, during the continuous filtration process of the filter barrel 30, impurities will continuously accumulate in the filter barrel 30, causing the filter holes of the filter barrel to become clogged. Therefore, this embodiment also includes a backwashing assembly 50, which includes a flushing pipe 51 and a waste residue tank 52. The flushing pipe 51 is close to the outer side of the filter barrel 30 and is arranged along the length of the filter barrel 30. The waste residue tank 52 is located on the inner side of the filter barrel 30 and directly below the flushing pipe 51. The waste residue tank 52 is discharged through the waste residue pipe 521. The wastewater collected after cleaning is pumped to a sedimentation tank by the first wastewater pump A. After settling in the sedimentation tank for a certain period of time, the supernatant clear liquid is pumped to the filtration device by the second wastewater pump B. The force of the pumped water flow drives the filter barrel to rotate, further filtering out suspended impurities in the clear liquid. In conjunction with the backwashing component, the filter screen of the filter barrel is backwashed. A certain pressure of flushing water is sprayed out through the flushing holes on the flushing pipe 51, which can also flush out the impurities accumulated inside the filter screen of the filter barrel, thereby maintaining the filter barrel's good filtration capacity. The flushed impurities will fall into the waste residue tank 52 under the action of gravity along with the flushing water, and then be discharged into the collection tank through the slag discharge pipe by the backwashing water for centralized treatment.

[0025] Of course, considering that sedimentation takes a certain amount of time to achieve a good sedimentation separation effect, the sediment is allowed to settle. In this embodiment, the sedimentation tank 60 preferably includes a first sedimentation tank 61 and a second sedimentation tank 62. The first sewage pump A is connected to the first sedimentation tank 61, and its outlet is close to the bottom of the first sedimentation tank 61. The first sedimentation tank 61 is connected to the second sedimentation tank 62 through a pipeline. The inlet end of the pipeline is close to the upper liquid level end of the first sedimentation tank 61, and the outlet end is close to the bottom of the second sedimentation tank 62. The pumping pipeline of the second sewage pump B is connected to the second sedimentation tank 62, and the connected pipeline is close to the upper liquid level end of the second sedimentation tank 62. Similarly, this maximizes the sedimentation and impurity removal effect while ensuring recycling.

[0026] It should be noted that in this embodiment, the outlet of the water purifier pump C is connected to the cleaning water inlet of the cleaning agent dryer, and is also connected to the inlet of the flushing pipe 51 through a flow regulating valve. The backwash water comes from a portion of the water purifier pump C, and the flushing force of the backwash water is adjusted by the flow regulating valve to meet the flushing requirements without affecting the water supply to the cleaning and drying machine. Example 2

[0027] The difference from Embodiment 1 is that the drive assembly 40 includes a hydraulic turbine 41, the output shaft of which meshes with the outer circumferential surface of the filter barrel 30 for transmission; the outlet of the second sewage pump B is connected to the inlet 42 of the hydraulic turbine 41; blades 32 are radially evenly distributed on the inner circumferential surface of the filter barrel 30 near the backwash pipe 44, and the outlet 43 of the hydraulic turbine 41 faces the blades 32. The hydraulic turbine 41 is driven by water to generate power on its output shaft. A gear disc 31 is provided on the filter barrel, and a gear meshing with it is provided at the output end of the hydraulic turbine 41, thereby driving the filter barrel to rotate; of course, the water flow from the outlet of the hydraulic turbine 41 will also impact the pressure plate 32, generating a certain amount of power to drive the filter barrel to rotate, thus further utilizing the power of the water flow.

[0028] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
