Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Example 1:

please refer to fig. 1 and fig. 2, which are a schematic diagram of a filter cloth filter 1 at a front view angle and a partial enlarged diagram of a schematic diagram at a side view angle when the filter disc 2 is disposed in the filter.

In conventional cloth filter, including a plurality of parallel arrangement's filter disc 2 and the center tube 3 that runs through a plurality of filter discs simultaneously, each filter disc 2's both sides are equallyd divide and are do not be equipped with a set of washing structure, and what then adopted in the present case is the utility model provides a cloth filter's wiper mechanism 1.

The cleaning mechanism 1 of the cloth filter comprises a mounting bracket 11, a flushing mechanism 12, a scraper mechanism 13 and a suction mechanism 14. The mounting bracket 11 is a three-layer bracket arranged horizontally, wherein the middle layer is arranged along the horizontal radial direction of the right side of the filter disc 2.

The side of the mounting bracket 11 at the uppermost layer close to the filter disc 2 is provided with the washing mechanism 12 which comprises a washing bracket 21, a water supply pipeline 22 and a spray head 23.

One side that installing support 11 leaned on filter disc 2 is equipped with wash support 21, wash support 21 to leaning on filter disc 2, leaning on the direction slope of below, form and have the inclined plane of 15 contained angles with filter disc 2, be provided with a row of a plurality of shower nozzles 23 on the inclined plane. So that the water jet sprayed by said spray head 23 also has an angle of 75 deg. with the filter disc 2. The water supply pipeline of the spray head 23 passes through the mounting bracket 11, and penetrates out of the bottom of the mounting bracket to extend to the outside.

The mounting bracket 11 of the lowest layer is provided with the suction mechanism 14 at a side close to the filter disc 2, and comprises a suction port (not shown in the drawing), a suction pipe 42 and a receiving groove 43.

The bottom of one side of the mounting bracket 11 close to the filter disc 2 is provided with the bearing groove 43, the top of the bearing groove and one side close to the mounting bracket 11 are open, the rest two sides are cambered surfaces, and the two ends are closed. The function is to guide the top-falling sludge into the suction opening.

The side wall of the mounting bracket 11 close to one side of the filter disc 2 is provided with the suction port, which is a long strip-shaped opening arranged between the bearing grooves 43. The other side of the opening is folded and abutted against the suction pipe 42, and penetrates out of the bottom of the mounting bracket 11 and extends to the outside.

Please refer to fig. 2 and fig. 3, wherein fig. 3 is a schematic structural diagram of an arrangement of the scraper 31 of the cleaning mechanism of the filter cloth filter 1 according to the present invention.

The side of the mounting bracket 11 close to the filter disc 2 in the middle layer is provided with the scraper mechanism 13, which comprises a scraper 31, a spring 32 and a clamping groove (not shown in the drawing).

The cross section (angle in fig. 2) of the scraper 31 is a right trapezoid, and the longitudinal section is an isosceles trapezoid. Under the cross section angle, its right angle waist one side fixedly connected with spring 32, spring 32's the other end with joint groove detachable is connected. The spring 32 pushes the scraper 31 into close contact with the surface of the filter disc 2.

Including two-layer the scraper 31, every layer all includes a plurality of along the horizontal direction arranges side by side the scraper 31, and two-layer alternate setting from top to bottom fills respectively another layer adjacent two the clearance between the scraper 31. The clamping grooves are arranged on one side of the mounting bracket 11 close to the filter disc 2 in a one-to-one corresponding arrangement mode with the springs 32/the scrapers 31.

The structure and the arrangement mode of the scraper 31 mainly aim to reduce the impact of water flow generated by the spray head 23 above, and prevent the scraper 31 from shaking greatly under the impact of the water flow to affect the attachment between the scraper 31 and the filter disc 2 and the scraping effect of the scraper 31. Further, the scraper 31 may increase the angle of the trapezoid, even forming a pyramid shape.

When the filter is implemented specifically, sewage is filled in the filter, and the filter disc 2 and the central tube 3 rotate anticlockwise under the driving of the power device. The central tube penetrates to the outside of the filter tank and is connected with a water pump, under the action of negative pressure generated by the water pump, sewage in the filter tank penetrates through the filter cloth on the surface of the filter disc 2, reaches the central tube 3 and reaches the outside of the filter tank, and sludge is intercepted on the surface of the filter disc 2.

The water supply pipe 22 and the suction pipe 42 are also connected to the corresponding water supply pump and suction pump, respectively. As the filter disc 2 rotates, its surface rubs against the scraper 31, scraping surface sludge and dropping into the receiving trough 43 to the suction opening and the suction pipe 42 with gravity and negative pressure from the suction pipe 42. Meanwhile, the water supply pipeline 22 also generates water flow on the spray head 23 to impact and clean the surface of the filter disc 2, and the impact force generated by the water flow with an inclined angle also assists the sludge to flow into the suction port.

Example 2:

fig. 4 is a partially enlarged view of a schematic structural view of a filter cloth filter cleaning mechanism 1 according to an embodiment 2 of the present invention from a side view angle.

The differences compared to example 1 are: the side of the mounting bracket 11 close to the filter disc 2 is provided with a scraper mechanism 13, a flushing mechanism 12 and a suction mechanism 14 in sequence from top to bottom.

Under the impact of the water flow, the sludge is sucked by the water flow and rapidly flows into the suction mechanism 14, and finally the residual sludge is further scraped by the scraper mechanism 13, so that the problem that the sludge is difficult to remove finally due to long-time adhesion is avoided. The other structures and operation modes are the same as those of embodiment 1.

The above only is the embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent processes made by the present specification can be changed, or directly or indirectly applied to other related technical fields, and all the same principles are included in the protection scope of the present invention.
