Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of filtering devices, in particular to a high-efficiency filtering device with three-effect self-cleaning. BACKGROUND

[0002] At present, filtering devices such as circulating water, soy sauce, food and beverage, etc. generally include a filter housing, a water inlet, a water outlet, a residue discharge port and a filter screen and other structures. The residues left after filtration accumulate inside the filtering device, especially on the filter screen, and are difficult to discharge from the residue discharge port, resulting in a decrease in flow rate or even blockage of the filtering device after a certain period of operation, thereby preventing normal operation. Therefore, the interior of the filtering device needs to be cleaned to ensure normal use of the filtering device. The existing filtering devices often use the way of stopping, disassembling and cleaning, which not only has low cleaning efficiency, consumes labor and causes a decrease in production efficiency. SUMMARY

Detailed Implementation

[0017] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0018] refer to Figures 1-7 This invention provides a high-efficiency filter device with triple-effect self-cleaning.

[0019] refer to Figures 1-3 The filtration device of this embodiment includes a device housing 100, a filter screen 200, and a cleaning spindle 300. The filter screen 200 is installed inside the device housing 100. One end of the cleaning spindle 300 extends into the device housing 100 and is located inside the filter screen 200, while the other end is located outside the device housing 100 and connected to a drive device 400. The drive device 400 drives the cleaning spindle 300 to perform both rotational and linear motion. The end of the cleaning spindle 300 extending into the device housing 100 is provided with a first rod 310, a second rod 320, and a third rod 330. 30. The first rod 310, the second rod 320 and the third rod 330 are arranged radially along the cleaning main shaft 300. The inner side of the cleaning main shaft 300 forms a water inlet channel 340 and a drain channel 350. The end of the first rod 310 is provided with a brush 311. The end of the second rod 320 is provided with a rinsing port 321. The interior of the second rod 320 is hollow, so that the rinsing port 321 is connected to the water inlet channel 340. The end of the third rod 330 is provided with a drain port 331. The interior of the third rod 330 is hollow, so that the drain port 331 is connected to the drain channel 350.

[0020] In the filtration device of this embodiment, the device housing 100 is provided with a liquid inlet 110, which is used to guide the liquid to be filtered into the inner side of the filter screen 200; in addition, the device housing 100 is also provided with a liquid outlet 120 and a drain outlet 130; the liquid to be filtered enters the filtration device from the liquid inlet 110, and is discharged from the liquid outlet 120 after being filtered by the filter screen 200.

[0021] In the filtration device of this invention embodiment, the brush 311 of the first rod 310 can clean the filter residue accumulated on the filter screen 200 by friction, which can quickly and initially clean the filter residue on the filter screen 200. However, a small amount of firmly adhered residual filter residue may be attached to the filter screen 200. Therefore, the second rod 320 needs to rinse the residual filter residue adhered to the filter screen 200 through the rinsing port 321. The third rod 330 discharges the sewage containing filter residue through the drain port 331. The three work together to achieve a self-cleaning function in a fixed position. Then, the cleaning main shaft 300 is driven by the driving device 400 to rotate and move linearly at the same time, so that the cleaning main shaft 300 moves linearly along its own axis. In this way, the cleaning main shaft 300 can not only achieve 360-degree cleaning, but also clean the filter screen 200 from head to tail.

[0022] Preferably, refer to Figure 4 In the filtration device of the present invention, the filter screen 200 can be an annular cylinder made of stainless steel, and multiple filter holes are distributed on the side of the annular cylinder.

[0023] In the filtration device of this embodiment, one end of the water inlet channel 340 is connected to the second rod 320, and the other end extends along the cleaning main shaft 300 to the outside of the device housing 100 and is connected to an external water source. One end of the drainage channel 350 is connected to the third rod 330, and the other end extends along the cleaning main shaft 300 to the outside of the device housing 100 and discharges the wastewater containing filter residue to the outside.

[0024] In the filtration device of this embodiment, the first rod 310, the second rod 320 and the third rod 330 are in the same position in the axial direction of the cleaning spindle 300; further, the first rod 310, the second rod 320 and the third rod 330 are arranged in an equidistant circular pattern.

[0025] Preferably, refer to Figures 5-7In the filtration device of the present invention, the inner wall of the device housing 100 is provided with a plurality of annular grooves 140 and a plurality of annular protrusions 150. The annular grooves 140 and annular protrusions 150 are staggered along the axial direction of the device housing 100. The filter screen 200 has an annular structure, and the outer side of the filter screen 200 is connected to the annular protrusion 150. The device housing 100 is also provided with a liquid outlet channel 160, which is located on one side of the outer circumference of the annular groove 140. The bottom of the annular groove 140 is provided with a liquid outlet hole for connecting to the liquid outlet channel 160. Generally speaking, under long-term use, the cleaning spindle 300 will cause the filter screen 200 to deform radially outward through friction and rinsing action, which will lead to damage to the filter screen. Therefore, in this embodiment of the present invention, the annular protrusion 150 is connected to the filter screen 200, which can effectively support the filter screen 200 and prevent it from deforming radially outward.

[0026] Furthermore, the liquid outlet channel 160 is provided with multiple channels and is distributed circumferentially, and each annular groove 140 is provided with multiple liquid outlet holes, which are distributed circumferentially along the annular groove 140.

[0027] Preferably, the filter screen 200 and the annular boss 150 are connected by welding; this arrangement can eliminate the gap between the filter screen 200 and the annular boss 150 and avoid filter residue.

[0028] In summary, the filtration device of this invention can automatically clean the filter residue without disassembly, greatly improving cleaning efficiency and production efficiency.

[0029] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
