Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a high-flow brush filter. Background Technology

[0002] Brush filters are commonly used in the field of fluid filtration and are widely applied in water treatment, industrial fluid purification and other scenarios. They can effectively remove solid particles from fluids and ensure the stable operation of subsequent equipment or meet fluid quality requirements.

[0003] Traditional brush filters typically have only a single filter cartridge inside, which limits the filtration area. When faced with the need to filter large flow rates, the processing capacity per unit time is insufficient, which can easily lead to problems such as untimely filtration and reduced filtration efficiency. Some unfiltered fluid may pass through directly, affecting the quality of the filtered fluid. Therefore, they are not suitable for the needs of efficient and economical high-flow filtration scenarios. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-flow brush filter.

[0006] A high-flow brush filter includes a cylinder, a filter screen, a flange, a lower end cap, an inlet, an outlet, a cleaning motor, a stainless steel brush, a rotating shaft, a connecting rod, a drain outlet, and an automatic drain valve. It also includes an electrical control box, control piping, a main pipe assembly, and a frame assembly. The control piping includes a control valve and a pressure transmitter. The main pipe assembly is located inside the cylinder. The stainless steel brush is fixedly connected to the rotating shaft via the connecting rod. The cleaning motor is driven by the rotating shaft to drive the stainless steel brush to rotate around the filter screen.

[0007] Preferably, the lower end cap is fixed to the bottom of the cylinder, the flange is located at the top of the cylinder, the liquid inlet is located at the lower end cap, the liquid outlet is located on one side of the cylinder, the drain outlet is located on the cylinder, and an automatic drain valve is provided on the drain outlet, and the automatic drain valve is electrically connected to the electrical control box.

[0008] Preferably, the filter screen has a wedge-shaped structure.

[0009] Preferably, the number of filters is at least three and they are evenly distributed along the length of the main component, and the axis of each filter is parallel to the axis of the main component.

[0010] Preferably, the two ends of the rotating shaft are rotatably connected to the frame assembly via bearings, and the axis of the rotating shaft is parallel to the axis of the main component.

[0011] Preferably, the connecting rods are spaced apart along the length of the rotation axis.

[0012] The beneficial effects of this utility model are:

[0013] This utility model has three or more filter cartridges inside the cylinder, which greatly increases the filtration area and water flow rate under the same cylinder diameter, meeting the filtration needs of large flow fluids. It uses automatic cleaning triggered by both timing and differential pressure, and the cleaning only takes tens of seconds, ensuring continuous filtration. A single unit can replace multiple traditional filters, reducing equipment purchase and installation costs, saving energy and space, and simplifying maintenance. It can also reduce equipment failures caused by poor filtration, indirectly reducing maintenance costs. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figures 1-2 A high-flow brush filter includes a cylinder 1, a filter screen 2, a flange 3, a lower end cap 4, an inlet 5, an outlet 6, a cleaning motor 7, a stainless steel brush 8, a rotating shaft 9, a connecting rod 10, a drain outlet 11, and an automatic drain valve 12. It also includes an electrical control box, control pipelines, a main pipe assembly, and a frame assembly. The control pipelines include a control valve and a pressure transmitter. The electrical control box and the control pipelines together constitute the control part to realize the automatic cleaning and draining process. The main pipe assembly is set inside the cylinder 1. The stainless steel brush 8 is fixedly connected to the rotating shaft 9 through the connecting rod 10. The cleaning motor 7 is driven by the rotating shaft 9 to drive the stainless steel brush 8 to rotate around the filter screen 2.

[0019] The electrical control box can set timing parameters, differential pressure threshold parameters, and cleaning time parameters. The control box panel is equipped with a rotary switch for switching working modes, including at least an automatic mode. When the equipment is in automatic mode, if the timing parameter reaches the set time, or the pressure transmitter detects that the differential pressure value at the filter inlet and outlet reaches the set differential pressure threshold, the self-cleaning process will be triggered.

[0020] The lower end cap 4 is fixed to the bottom of the cylinder 1, the flange 3 is set at the top of the cylinder 1, the liquid inlet 5 is opened at the lower end cap 4, the liquid outlet 6 is set on one side of the cylinder 1, the drain outlet 11 is set on the cylinder 1, and an automatic drain valve 12 is set on the drain outlet 11, which is controlled by the electrical control box to open and close to complete the draining action.

[0021] The filter screen 2 is a wedge-shaped filter screen structure. There are at least three filter screens 2 and they are evenly distributed along the length of the main component. The axis of each filter screen 2 is parallel to the axis of the main component. The two ends of the rotating shaft 9 are rotatably connected to the frame component through bearings. The axis of the rotating shaft 9 is parallel to the axis of the main component. The connecting rods 10 are spaced apart along the length of the rotating shaft 9.

[0022] In use, this utility model first sets parameters such as timing duration, differential pressure threshold, and cleaning time through the electrical control box (this is existing technology). Then, the control box panel knob switch is switched to "automatic" mode. The medium to be treated enters the cylinder 1 through the inlet 5. When it flows through the filter screen 2 in the main pipe assembly, impurities are intercepted on the surface of the filter screen 2. The filtered clean medium is discharged through the outlet 6. During this period, the pressure transmitter monitors the differential pressure between the filter inlet and outlet in real time, and the control box keeps a synchronized timer. When the timer reaches the set duration or the differential pressure reaches the set threshold, the system triggers self-cleaning. The cleaning motor 7 starts and drives the rotating shaft 9 to rotate. The rotating shaft 9 drives the stainless steel brush 8 to rotate and brush around the filter screen 2 through the connecting rod 10. After brushing for the set cleaning time, the automatic drain valve 12 opens, and impurities are discharged from the drain port 11 along with some of the medium. After the drain is completed, the automatic drain valve 12 closes, the cleaning motor 7 stops running, and the equipment returns to the initial filtration state and enters the next cycle.

[0023] 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. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
