Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment equipment, and in particular to an online slag removal wastewater filtering device. Background Art

[0002] In the wastewater treatment system, the filter is a commonly used filter residue device. After the wastewater enters the filter cavity, it will flow through the filter screen. The filter screen can filter out the residue and particles with pore sizes exceeding the filter holes, so that the final drainage meets the emission standards. However, as the filtering time progresses, the filter screen will gradually be blocked by the filter residue, requiring manual regular shutdown and cleaning, which affects the equipment's operating efficiency. Summary of the invention

[0003] The technical problem to be solved by the present invention is that, in view of the defects and shortcomings of the prior art, an online slag-removing wastewater filtration device is proposed, which can realize online cleaning of the filter screen without stopping the machine, and the equipment has high operating efficiency.

[0018] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0019] like Figure 1 As shown, the online slag removal wastewater filtering device according to the embodiment of the present invention comprises a filter box 10 , a filter screen 3 and a vibrating rod 2 .

[0020] Specifically, a slag discharge pipe 9 is provided on one outer wall of the filter box 10 , the filter screen 3 is arranged in the filter box 10 with one end thereof extending into the slag discharge pipe 9 and the other end thereof inclined upward in a direction away from the slag discharge pipe 9 , and the vibration rod 2 is in contact with the filter screen 3 .

[0021] like Figure 1 As shown, a material inlet 1 is provided at the top of the filter box 10, a vibrating rod 2 is inserted from the top of the filter box 10 and the lower end contacts the filter screen 3, a filtrate outlet 4 is provided at the bottom of the filter box 10, a slag discharge pipe 9 is provided on the right side wall of the filter box 10, the left end of the filter screen 3 is raised, and the right end is tilted downward and partially extends into the slag discharge pipe 9.

[0022] It is understandable that as the filtration system runs, more and more filter residue will remain on the filter screen 3, eventually causing the holes of the filter screen 3 to be clogged. At this time, the vibration rod 2 in contact with the filter screen 3 is started, and the vibration rod 2 can be used to vibrate the filter screen 3 to make the clogged filter residue escape from the holes of the filter screen 3. Since the filter screen 3 is tilted downward, the escaped filter residue can move along the filter screen 3 toward the slag discharge pipe 9, thereby realizing online cleaning of the filter screen 3.

[0023] In the online slag removal wastewater filtration device of the embodiment of the present invention, a slag discharge pipe 9 is provided on the outer wall of one side of the filter box 10, the filter screen 3 is arranged in the filter box 10 and one end thereof extends into the slag discharge pipe 9, and the other end is arranged to be inclined upward in the direction away from the slag discharge pipe 9, and the vibrating rod 2 is in contact with the filter screen 3. Therefore, when the filter screen 3 is blocked, starting the vibrating rod 2 can vibrate the filter screen 3, so that the blocked filter residue can be removed from the holes of the filter screen 3, and since the filter screen 3 is arranged to be inclined downward, the removed filter residue can move along the filter screen 3 toward the slag discharge pipe 9, thereby realizing online cleaning of the filter screen 3 without stopping the machine, and the equipment has high operating efficiency.

[0024] Furthermore, if Figure 1 As shown, the online slag removal wastewater filtration device also includes a slag discharge pipe 5, which is located outside the filter box 10 and is vertically arranged, and is connected to the slag discharge pipe 9. A piston that can move up and down is inserted into the slag discharge pipe 5. Therefore, the filter residue discharged from the slag discharge pipe 9 can flow into the slag discharge pipe 5, and the slag discharge pipe 5 can be used as a temporary storage container for the filter residue, and the piston can move up and down to take the filter residue out of the slag discharge pipe 5 and transfer it to the next treatment process.

[0025] Furthermore, if Figure 1 As shown, the bottom of the slag discharge pipe 5 is provided with an openable and closable slag discharge port 8. It is understandable that in the long-term filtering operation, the slag discharge pipe 5 may have filter residues accumulated at the bottom, causing the slag discharge system to be unable to operate normally. At this time, the slag discharge port 8 can be opened to directly clean the accumulated filter residues from the bottom of the slag discharge pipe 5 without disassembling and cleaning the entire slag discharge pipe 5.

[0026] Furthermore, if Figure 1 As shown, a detachable plugging cover is provided at the slag discharge port 8. Optionally, the plugging cover can be a rubber plug.

[0027] In some embodiments, Figure 1 As shown, an inspection port is provided on the outer wall of the slag discharge pipe 5, and a retractable inspection rod 7 is provided at the inspection port. It should be noted that the filter residue discharged into the slag discharge pipe 5 may be blocked by the filter residue due to adhesion to the pipe wall or excessive accumulation. At this time, the filter residue cannot fall smoothly, and the inspection rod 7 can be operated to move back and forth along the inspection port to disturb the filter residue, so as to loosen the blockage and ensure the normal falling of the filter residue and the normal movement of the piston.

[0028] Furthermore, if Figure 1As shown, the inspection port is located on the side of the slag discharge pipe 5 away from the filter box 10. In other words, there is no filter box 10 to interfere with the operating space on the side facing the inspection port, which is convenient for personnel to operate the inspection rod 7.

[0029] Furthermore, if Figure 1 As shown, the inspection port is opposite to the slag discharge pipe 9. It is understandable that the slag enters the slag discharge pipe 5 from the slag discharge pipe 9, and the outlet position of the slag discharge pipe 9 is most likely to block the slag discharge pipe 5. The inspection port is set corresponding to this position to facilitate solving the problem of slag discharge pipe 5 being blocked.

[0030] In some embodiments, Figure 1 As shown, a socket is provided on the outer wall of the slag discharge pipe 9, and the socket is used to insert the slag blocking plate 6. Therefore, when the filter screen 3 does not need to discharge slag, the slag blocking plate 6 can be inserted into the socket, and when the slag needs to be discharged, the slag blocking plate 6 can be pulled out. In addition, when the slag discharge pipe 5 is blocked, the slag blocking plate 6 can also be inserted, and the slag blocking plate 6 can be pulled out after the maintenance is completed.

[0031] In some embodiments, Figure 1 As shown, the slag discharge pipe 9 extends downwardly in a direction away from the filter box 10. Therefore, after the filter residue enters the slag discharge pipe 9, it can flow along the slag discharge pipe 9 toward the slag discharge pipe 5 under the action of gravity, which is convenient for improving the smoothness of slag discharge and improving the slag discharge efficiency.

[0032] Furthermore, the vibrating rod 2 is arranged adjacent to the end of the filter screen 3 away from the slag discharge pipe 9 .

[0033] Furthermore, the slag discharge pipe 9 gradually shrinks in the direction away from the filter box 10. Therefore, on the one hand, the gradually shrinking structure of the slag discharge pipe 9 can be used to guide the flow of the filter residue and improve the slag discharge efficiency, and on the other hand, the size of the slag discharge pipe 9 and the subsequent slag discharge pipe 5 can be reduced to save materials.
