Description

Technical Field

[0001] This utility model relates to the field of disc filter technology, and more specifically, to a stepped universal washing device for disc filters. Background Technology

[0002] Disc filters are an indispensable device in media conveying pipelines, typically installed at the inlet of pressure reducing valves, pressure relief valves, level control valves, or other equipment to remove impurities from the media, protecting the valves and equipment. When fluid enters the filter cartridge containing a filter screen of a specific size, impurities are blocked, while the clean filtrate is discharged from the filter outlet. Currently, the washing device for disc filters mainly consists of a combination of fixed metal pipes and fan-shaped nozzles. This involves installing fan-shaped nozzles through holes in the metal pipe to wash the fan-shaped surface of the disc filter. However, this method has drawbacks: the impact force of the fan-shaped nozzles is too high, easily dispersing the filter cake and affecting the filter's performance; the fixed nozzles result in a fixed and incomplete washing surface, leading to poor washing effect; and the limited washing location restricts its applicability to various equipment. Therefore, we propose a stepped universal washing device for disc filters. Utility Model Content

[0003] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a stepped universal rinsing device for disc filters, which can solve the problems of large impact force, single rinsing position, and poor rinsing effect of disc filter rinsing devices.

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] A stepped universal scrubbing device for a disc filter includes a disc filter body with multiple filter discs and multiple support mechanisms. A first spray pipe is mounted at the top of each support mechanism. Multiple manual regulating valves are fixedly installed on the side of the first spray pipe. Second spray pipes are fixedly connected to the ends of each of the manual regulating valves. Multiple right-angle adapters are fixedly connected to the sides of the second spray pipes. Metal universal tubes are fixedly connected to the bottom of one end of each of the right-angle adapters. PP spatula nozzles are fixedly connected to the bottom of each of the metal universal tubes. A pressure transmitter is mounted in the middle of the first spray pipe. A first flange is mounted at the end of the first spray pipe, and a flow meter is fixedly mounted at the end of the first flange.

[0006] As a preferred embodiment of the present invention, the support mechanism includes a mounting base installed on the disc filter body, a column fixedly connected to the top surface of the mounting base, a support base fixedly connected to the top of the column, and a U-shaped pipe clamp sleeved on the top of the support base. The first spray pipe passes through the inner side of the support base and the U-shaped pipe clamp.

[0007] As a preferred embodiment of this utility model, the length of the plurality of metal universal tubes gradually shortens along the axial direction of the second spray pipe, and the PP spatula nozzle is located inside the filter disc.

[0008] In a preferred embodiment of this utility model, the outer diameter of the first spray pipe is equal to the inner diameter of the U-shaped pipe clamp, and the bottom surface of the first spray pipe is in contact with the top surface of the support base.

[0009] As a preferred embodiment of this utility model, the mounting base is provided with multiple mounting holes.

[0010] As a preferred embodiment of this utility model, the flow meter is provided with a second flange at its end.

[0011] The advantages of this utility model are:

[0012] This invention employs an overflow-type PP spatula nozzle, which has no impact force and provides excellent rinsing effect. Simultaneously, the metal universal tubes have a long service life, allowing for arbitrary changes in the spray position of the PP spatula nozzles according to equipment operation conditions, ensuring rinsing effectiveness. Furthermore, the multiple metal universal tubes are arranged in a stepped configuration, providing a wider cleaning area and reducing water consumption. The first spray pipe is equipped with a flow meter and pressure transmitter, enabling real-time monitoring of the entire device's operation. Each second spray pipe is controlled by an individual manual regulating valve, allowing for reasonable distribution of rinsing water, achieving efficient rinsing, reducing water consumption, and improving the practicality of this stepped universal rinsing device for disc filters.

[0027] In this embodiment, only one side of the second spray pipe 6 at both ends of the first spray pipe 4 is provided with a metal universal tube 8 and a PP spatula nozzle 9. The metal universal tube 8 and the PP spatula nozzle 9 are used to spray the outer sides of the two outermost filter discs 2. The remaining second spray pipes 6 on the side of the first spray pipe 4 are provided with metal universal tubes 8 and PP spatula nozzles 9 on both sides. The metal universal tube 8 and the PP spatula nozzles 9 are used to spray the sides of two adjacent filter discs 2. The PP spatula nozzles 9 are overflow spatula nozzles.

[0028] For details, please refer to Figures 1 to 3 The support mechanism 3 includes a mounting base 14 installed on the disc filter body 1. A column 15 is fixedly connected to the top surface of the mounting base 14. A support base 16 is fixedly connected to the top of the column 15. A U-shaped pipe clamp 17 is sleeved on the top of the support base 16. The first spray pipe 4 passes through the inner side of the support base 16 and the U-shaped pipe clamp 17.

[0029] In this embodiment, the first spray pipe 4 is fixedly supported on the side of the filter disc 2 on the body 1 of the disc filter by the cooperation of the mounting base 14, the column 15, the support base 16 and the U-shaped pipe clamp 17.

[0030] For details, please refer to Figure 6 The length of multiple metal universal tubes 8 gradually shortens along the axial direction of the second spray pipe 6, and the PP spatula nozzle 9 is located inside the filter plate 2.

[0031] In this embodiment, metal universal tubes 8 of different lengths are used to make multiple PP spatula nozzles 9 located at different heights, thereby performing stepped spraying on the filter plate 2 at different heights.

[0032] For details, please refer to Figure 3 The outer diameter of the first spray pipe 4 is equal to the inner diameter of the U-shaped pipe clamp 17, and the bottom surface of the first spray pipe 4 is in contact with the top surface of the support base 16.

[0033] In this embodiment, the stability of the support base 16 and the U-shaped pipe clamp 17 in supporting and fixing the first spray pipe 4 is ensured.

[0034] For details, please refer to Figure 2 The mounting base 14 has multiple mounting holes 18.

[0035] In this embodiment, the mounting base 14 is fixedly installed on the disc filter body 1 by means of mounting holes 18 and bolts.

[0036] For details, please refer to Figure 2 The flow meter 11 is provided with a second flange 13 at its end.

[0037] In this embodiment, the second flange 13 is connected to the external spray water supply pipe so that the spray water is introduced into the first spray pipe 4 through the flow meter 11.

[0038] Working principle: The first spray pipe 4 is supported by the mounting base 14, column 15, support base 16, and U-shaped pipe clamp 17. The metal universal pipe 8 and PP spatula nozzle 9 are placed between two adjacent filter discs 2. When it is necessary to clean the sludge on the side of the filter disc 2, the external spray water is first pumped into the inner cavity of the first spray pipe 4 through the second flange 13. The flow rate is monitored by the flow meter 11, and the water pressure is detected by the pressure transmitter 12. Then, the water is distributed... Do not open the manual adjustment valve 5 on the side of the first spray pipe 4, so that the water in the first spray pipe 4 enters the second spray pipe 6. Then, through the right-angle adapter 7, guide the water in the second spray pipe 6 into multiple metal universal tubes 8, so that the water in the metal universal tubes 8 is sprayed from the PP spatula nozzle 9 onto the side of the filter plate 2 to spray the filter plate 2. Finally, during spraying, you can move the metal universal tube 8 to adjust the spraying position of the PP spatula nozzle 9 to ensure the spraying effect.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto.
