Description

Technical Field

[0001] The utility model belongs to the field of water treatment, and particularly relates to a self-cleaning brush filter. Background Art

[0002] The brush filter has an automatic cleaning function. When the impurities accumulated on the filter screen surface increase and cause the pressure difference between the inlet and outlet to reach the set value, the controller will start the automatic cleaning process. The cleaning process includes opening the drain valve, driving the stainless steel brush to rotate by a motor or a hydraulic piston, brushing the dirt on the inner side of the filter screen, and discharging it through the drain valve. The specific structure is as Figure 1 shown.

[0003] On the above basis, since the filter screen itself is a rigid structure, when using a stainless steel brush to clean it, the wear of the stainless steel brush is very large. Therefore, the stainless steel brush needs to be replaced frequently. However, on the one hand, the steel brush is fixed on the rotating shaft, and the rotating shaft is connected to the bearing seat on the head, and cannot be separated. On the other hand, the head is usually connected to the tank body through a large number of screw structures, and the disassembly and assembly are not convenient. Content of the Utility Model

[0005] Technical solution: The utility model provides a self-cleaning brush filter, which includes an external structure and an internal structure. The external structure includes a tank body, the bottom end of which is connected to a water inlet pipe, the side surface of which is connected to a water outlet pipe, and the top end of which is provided with a head. Two groups of ear blocks are symmetrically arranged between the head and the tank body, and a screwing mechanism is arranged between the ear blocks for connection; in addition, a drain pipe is connected to the head, a bearing is connected in the middle, and a rotating rod passes through the bearing; at the same time, a driving mechanism for driving the rotating rod to rotate is also arranged on the head; the internal structure includes a hollow cylindrical steel brush, the steel brush is sleeved on the rotating rod, and a detachable limiting mechanism is arranged on the rotating rod to limit and fix the steel brush; in addition, a cylindrical filter screen is connected inside the tank body, and the steel brush is inside the cylindrical filter screen.

[0006] Further, the limiting mechanism includes a baffle fixed and sleeved on the outer peripheral side of the rotating rod for abutting against the top end of the steel brush and a detachable limiting mechanism arranged at the bottom end of the rotating rod for abutting against the bottom end of the steel brush.

[0007] Further, the limiting mechanism includes a threaded hole opened at the bottom end of the rotating rod, a bolt is connected in cooperation with the threaded hole, and the head of the bolt is used for abutting against the bottom end of the steel brush.

[0008] Further, the screwing mechanism includes a connection hole opened through the ear block, and a combination bolt is connected in cooperation with the connection hole between each group of upper and lower symmetric ear blocks.

[0009] Furthermore, the driving mechanism includes a servo motor installed at the top end of the head, and a speed reducer is connected between the servo motor and the rotating rod.

[0010] Furthermore, a through hole is penetrated through the middle of the head at the position corresponding to the bearing, and the bearing is installed in this through hole. And preferably, the bearing is a combined bearing.

[0011] Technical effects: In the present utility model, the top end of the steel brush is blocked by the baffle, and the bottom end is blocked by the detachable bolt. On the one hand, the baffle and the bolt limit and fix the steel brush on the rotating rod to ensure its normal operation; on the other hand, when the bolt is removed, the steel brush can be taken out from the bottom end of the rotating rod. On this basis, between the head and the tank body, the ear blocks and the screwing mechanism replace a large number of existing bolt structures, making it more convenient to remove the head. After the head is removed, the steel brush can be taken off from the rotating rod for replacement by using the above principle. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application; it is obvious that the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0020] The self-cleaning brush filter provided by this specific embodiment, as Figure 2 and Figure 3 shown, includes an external structure and an internal structure, wherein:

[0021] The external structure includes a tank body 1, the bottom end of which is connected to a water inlet pipe 2, the side surface of which is connected to a water outlet pipe 3, and the top end of which is provided with a head 4. Two groups of ear blocks 5 are symmetrically arranged between the head 4 and the tank body 1, and a screwing mechanism 6 is arranged between the ear blocks 5 for connection. The screwing mechanism 6 includes connection holes penetrating through the ear blocks 5, and a combination bolt 601 is connected between each group of upper and lower symmetric ear blocks 5 through the connection holes; in addition, a sewage discharge pipe 7 is connected to the head 4, and a bearing 8 is connected to the middle of the head 4. A rotating rod 9 penetrates through the bearing 8. Specifically, a through hole is penetrated through the middle of the head 4 at a position corresponding to the bearing 8, and the bearing 8 is installed in this through hole. And the bearing 8 is preferably a combined bearing; at the same time, a driving mechanism 10 for driving the rotating rod 9 to rotate is also arranged on the head 4, as Figure 3 shown, the driving mechanism 10 includes a servo motor 1001 installed at the top end of the head 4, and a speed reducer 1002 is connected between the servo motor 1001 and the rotating rod 9.

[0022] The internal structure includes a hollow cylindrical steel brush 11, the steel brush 11 is sleeved on the rotating rod 9, and a detachable limiting mechanism is arranged on the rotating rod 9 to limit and fix the steel brush 11; in addition, a cylindrical filter screen 12 is connected inside the tank body 1, and the steel brush 11 is inside the cylindrical filter screen 12. Specifically, as Figure 4 and Figure 5As shown in the figure, the limiting mechanism includes a baffle 13 fixedly sleeved on the outer peripheral side of the rotating rod 9 for abutting against the top end of the steel brush 11 and a detachable limiting mechanism 14 provided at the bottom end of the rotating rod 9 for abutting against the bottom end of the steel brush 11. The limiting mechanism 14 includes a threaded hole 1401 opened at the bottom end of the rotating rod 9, and a bolt 1402 is connected in cooperation with the threaded hole 1401.
