Description

Technical Field

[0001] The utility model relates to the field of sewage treatment equipment, in particular to a sewage filtering device. Background Art

[0002] At present, in order to improve the quality of sewage filtration, a filter chamber has been developed in which an inlet overflow channel and an outlet overflow channel are respectively arranged on both sides of the sewage filter chamber (for example: the filter chamber disclosed in the patent document with Chinese authorization announcement number CN220012373U, which is a prior patent application filed by the inventor of the present application (Liang Jinrong) as the applicant). In this filter chamber, the sewage filter chamber is filled with a filter material with a filtering function.

[0003] In actual use, sewage enters the upper end of the sewage filter chamber through the water inlet overflow channel, and then overflows from the water outlet overflow channel after passing through the filtered material from top to bottom. Although this can achieve a very stable and reliable filtering effect, during the filtering process, the impurities attached to the filtered material in the sewage filter chamber will gradually decrease from top to bottom.

[0004] Since there is no device that can automatically clean the filter material on the existing filter chamber, when the upper filter material has too many impurities attached to it and affects the filtering performance, the filter chamber is generally opened manually and the filter material is taken out for cleaning. Since impurities generally fall off when the upper filter material is taken out, this will cause the filter material with less impurities attached to the lower layer to also be attached with more impurities. Therefore, when cleaning and maintaining the filter material, all the filter material is generally taken out for cleaning and maintenance. The process of cleaning and maintaining the filter material is very cumbersome, which not only increases the labor intensity of the workers, but also leads to very low efficiency of cleaning and maintenance, which easily affects the sewage treatment efficiency.

[0005] Although there is now a cleaning operation of opening the filter chamber and directly flushing the filter with a high-pressure water gun, this cleaning will cause impurities attached to the upper layer to move to the lower layer. In addition, the filter material in the sewage filter chamber is mostly relatively dense and thick, so it is difficult for high-pressure water to act on the filter material in the lower layer. This will cause more impurities to adhere to the filter material in the lower layer, which will affect the filtration efficiency.

[0006] Therefore, it is very necessary to design a sewage filtering device with ultrasonic cleaning function to solve the above technical problems. Utility Model Content

[0007] The purpose of the utility model is to solve the above-mentioned problems and shortcomings, and to provide a sewage filtering device with an ultrasonic cleaning function, which can automatically and quickly clean and maintain the filtered material without the need for workers to participate in the cleaning process, which can not only reduce the labor intensity of workers, but also greatly improve the efficiency of cleaning and maintenance, thereby helping to improve the sewage treatment efficiency.

[0008] The technical solution of the utility model is achieved in this way:

[0009] A sewage filtering device with ultrasonic cleaning function comprises a filter box, the inner cavity of the filter box constitutes a filter cavity, two sides of the filter box are respectively provided with a water inlet overflow channel and a water outlet overflow channel connected to the filter cavity, the filter box is filled with a filter material, and the filter material is characterized in that at least one ultrasonic transducer is provided on the filter box, the ultrasonic wave generated by the ultrasonic transducer can act on the filter material, and a plurality of residue suction mesh tubes are inserted in the filter material.

[0010] Preferably, the slag suction network pipes are arranged vertically side by side.

A limiting mesh cylinder is inserted in the insertion hole, and the limiting mesh cylinder can be removably embedded in the cavity wall of the filter cavity after passing the filter material. The residue suction mesh tube is placed in the limiting mesh cylinder, and the convex tube portion is connected to a residue suction pipe.

[0014] Preferably, a positioning convex ring is provided on the outer circumferential surface of the end of the slag suction pipe, and a sealing sleeve cover is sleeved on the slag suction pipe. The sealing sleeve cover is threadedly sleeved on the convex pipe part, and the positioning convex ring is clamped between the inner wall of the sealing sleeve cover and the outer end surface of the convex pipe part.

[0015] Preferably, sealing rubber rings are respectively sandwiched between the positioning convex ring and the inner wall of the sealing sleeve cover, and between the positioning convex ring and the outer end surface of the convex tube portion.

[0016] The beneficial effects of the utility model are as follows: at least one ultrasonic transducer is arranged on the filter box of the sewage filter device, and the ultrasonic energy generated by the ultrasonic transducer can act on the filter material, and a plurality of residue suction net pipes are inserted in the filter material. In this way, the ultrasonic wave can be used to make the impurities attached to the filter material fall off fully, and the residue suction net pipe can be used to quickly suck away the impurities vibrated by the ultrasonic wave.

[0020] like Figure 1 and Figure 2 As shown, a sewage filtering device with ultrasonic cleaning function described in the utility model comprises a filter box 1, the inner cavity of the filter box 1 constitutes a filter cavity 11, and the two sides of the filter box 1 are respectively provided with an inlet overflow channel 12 and an outlet overflow channel 13 connected to the filter cavity 11, and the filter box 1 is filled with a filter 2. To achieve the purpose of the invention of the utility model, at least one ultrasonic transducer 3 is provided on the filter box 1, and the ultrasonic energy generated by the ultrasonic transducer 3 acts on the filter 2, and a plurality of residue suction mesh tubes 4 are inserted in the filter 2.

[0021] At least one ultrasonic transducer 3 is arranged on the filter box 1 of the sewage filter device, and the ultrasonic energy generated by the ultrasonic transducer 3 acts on the filter 2, and a plurality of residue suction net pipes 4 are inserted in the filter 2. In this way, the ultrasonic wave can be used to make the impurities attached to the filter 2 fall off fully, and the residue suction net pipe 4 can help to quickly suck away the impurities vibrated by the ultrasonic wave, so that the sewage filter device can automatically and quickly clean and maintain the filter without the need for workers to participate in the cleaning process, which can not only reduce the labor intensity of the workers, but also greatly improve the efficiency of cleaning and maintenance, thereby helping to improve the sewage treatment efficiency.

[0022] The use of the residue suction net pipe 4 can achieve the effect of blocking the filter material 2, thereby preventing the filter material from being sucked away by the residue suction net pipe 4, so that the sewage filtering device has very high stability and reliability.

[0023] like Figure 1 As shown, when the sewage filtering device is connected in series to a multi-stage sewage treatment device, domestic sewage flows from the previous treatment chamber 10 (for example, a high-temperature treatment chamber) into the upper end of the filter chamber 11 through the water inlet overflow channel 12, and the filtered domestic sewage flows from the lower end of the filter chamber 11 through the water outlet overflow channel 13 into the next treatment chamber 20 (for example, a disinfection and sterilization chamber). This can not only meet the demand for sequential sewage treatment, but also reduce energy consumption, which can well meet the needs of actual use.

[0024] like Figure 2 and Figure 3 As shown, the filter box 1 is surrounded by steel plates, the ultrasonic transducer 3 is arranged on the outer wall of the filter box 1, the ultrasonic transducer 3 is electrically connected to the ultrasonic generator (not shown in the figure), a slag suction pipe 5 is arranged outside the filter box 1, and the slag suction pipe 5 is connected to the slag suction net pipe 4, and a slag suction pump (not shown in the figure) is connected in series to the slag suction pipe 5, so as to meet the actual cleaning and maintenance needs.

[0025] like Figure 1 As shown, when a plurality of filter chambers 11 connected by overflow channels 14 are opened on the filter box 1, a filter material 2 is arranged in each filter chamber 11, and a plurality of residue suction mesh tubes 4 are inserted in each filter material 2, and a plurality of ultrasonic transducers 3 acting on the filter material 2 in each filter chamber 11 are arranged on the outer wall of the filter box 1, so that the requirements of automatic cleaning and maintenance can be realized during continuous filtration.

[0026] like Figure 1 and Figure 2 As shown, the residue suction net pipes 4 are arranged side by side vertically. This can produce a very good residue suction effect, so as to reduce the probability of impurities falling down and moving downward, thereby improving the cleaning quality. In addition, the lower filter 2 is less affected by impurities, thereby reducing the aging speed of the lower filter 2, thereby extending the overall service life.

[0027] like Figure 1 As shown, at least two slag suction net pipes 4 arranged side by side in a transverse direction constitute a slag suction net pipe group, and the slag suction net pipe group has several groups, and each slag suction net pipe group is arranged side by side vertically. This can achieve a very comprehensive and effective slag suction effect, so that the impurities that fall down can be sucked away more comprehensively and effectively, thereby further improving the cleaning quality.

[0028] like Figure 1As shown, when multiple slag suction network pipe groups are provided, each slag suction network pipe group can be connected to the same slag suction pipe 5 or to different slag suction pipes 5, so as to meet the actual slag suction needs.

[0029] like Figure 2 As shown, there are several ultrasonic transducers 3, and each ultrasonic transducer 3 is arranged vertically side by side. This can make the effect of ultrasonic waves more comprehensive and effective, thereby helping to further improve the quality of ultrasonic cleaning. Embodiment expansion: When multiple ultrasonic transducers 3 are provided, each ultrasonic transducer 3 can be electrically connected to the same ultrasonic generator, so that the need for each ultrasonic transducer 3 to generate ultrasonic waves can be met.

[0030] like Figure 2 and Figure 3 As shown, a convex tube portion 15 is provided on the outer wall of the filter box 1, and the inner hole of the convex tube portion 15 constitutes an insertion hole 16 that penetrates into the filter cavity 11, and a limited net cylinder 6 is inserted into the insertion hole 16, and the limited net cylinder 6 can be detachably embedded in the cavity wall of the filter cavity 11 after passing through the filter 2, and the residue suction net pipe 4 is placed in the limited net cylinder 6, and the convex tube portion 15 is connected with a residue suction pipe 5. The limited net cylinder 6 can prevent the filter 2 from directly acting on the residue suction net pipe 4, so that the removal of the residue suction net pipe 4 will not be affected by the filter 2, thereby ensuring that the removal and maintenance of the residue suction net pipe 4 is very convenient.

[0031] The limiting mesh cylinder 6 is a stainless steel mesh cylinder, and the slag suction mesh tube 4 is a stainless steel mesh tube, so that the limiting mesh cylinder 6 and the slag suction mesh tube 4 have high structural strength and durability, thereby being able to meet the needs of actual use very well.

[0032] The slag suction pipe 5 is provided with a switch valve (not shown in the figure), so that the slag suction pipe 5 can be closed during normal filtration, thereby preventing the slag suction pipe 5 from affecting normal filtration.

[0033] like Figure 3 As shown, a positioning convex ring 51 is provided on the outer circumferential surface of the end of the slag suction pipe 5, and a sealing sleeve 7 is sleeved on the slag suction pipe 5. The sealing sleeve 7 is threadedly sleeved on the convex pipe part 15, and the positioning convex ring 51 is clamped between the inner wall of the sealing sleeve 7 and the outer end surface of the convex pipe part 15. This can make the docking of the slag suction pipe 5 very convenient and stable, which can not only improve the convenience of disassembly and assembly, but also ensure that the sewage filtering device has high reliability.

[0034] like Figure 3 As shown, a sealing rubber ring 8 is respectively sandwiched between the positioning convex ring 51 and the inner wall of the sealing sleeve cover 7, and between the positioning convex ring 51 and the outer end surface of the convex tube portion 15. This can further improve the sealing performance of the docking, thereby helping to further improve the reliability of the sewage filtering device.

[0035] The filter 2 is a nano-filter material or a metal filter with silver ions attached to the surface, which can well meet the needs of actual use. When a metal filter is used, the limiting mesh cylinder 6 may not be provided.
