Description

Technical Field

[0001] The utility model relates to the technical field of filtering and anti-blocking, in particular to an energy-saving and environmentally friendly sewage filtering and anti-blocking device. Background Art

[0002] Sewage refers to the general term for water discharged from production and life activities. In order to make the sewage meet the water quality requirements for draining a certain water body or reusing it, it needs to be purified. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, catering and other fields, and is increasingly entering the daily lives of ordinary people. When treating sewage, we usually filter the sewage and add flocculants, disinfectant powders and other treatment agents to purify the sewage.

[0003] Publication No. CN217780899U discloses an energy-saving and environmentally friendly sewage treatment equipment, including a sewage treatment tank, a stirring assembly and a filtering assembly; the stirring assembly rotates with the sewage treatment tank; the filtering assembly slides with the sewage treatment tank; the filtering assembly includes a filter plate; the filter plate is symmetrically fixedly connected with slide rails on both sides; the filter plate surface is symmetrically fixedly connected with a hydraulic cylinder near the two sides; the top of the hydraulic cylinder is fixedly connected with an L-shaped connecting rod; the bottom of the L-shaped connecting rod is fixedly connected with a limit plate; the L-shaped connecting rod slides with an anti-blocking assembly. Although this type of sewage treatment equipment regularly uses external lifting equipment to pull the filtering assembly together with the anti-blocking assembly out of the sewage treatment tank for unified cleaning; the entire device effectively prevents the filter plate from being blocked and improves the sewage purification effect. However, each cleaning requires the filtering assembly and the anti-blocking assembly to be pulled out together, which may affect the continuity of sewage treatment. In addition, if the cleaning is not timely, it may cause blockage or reduce the purification effect, and the regular use of external lifting equipment for cleaning will undoubtedly increase the maintenance cost of the equipment. This includes the rental or purchase cost of the lifting equipment, the operating cost, and the possible maintenance cost. Therefore, improvements are needed. Utility Model Content

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, during actual use, sewage enters through the water inlet pipe, and then is filtered through the coarse filter screen and the fine filter screen respectively, and finally the purified sewage is discharged from the water outlet pipe to complete the processing.

The utility model can cut large-volume foreign matter into pieces before the sewage enters the sewage tank through the cutter, effectively preventing these foreign matter from clogging the water inlet pipe and the filter screen, and ensuring the continuous and stable operation of the sewage tank. Due to the anti-blocking function, the device reduces the frequency of shutdown maintenance caused by blockage, thereby reducing maintenance cost and time cost. At the same time, the eccentric wheel and the cutter are driven by the motor to automatically cut large-volume foreign matter, avoiding the need for manual cleaning of blockages, and improving the automation degree and work efficiency of sewage treatment.

[0014] 2. In the utility model, during actual use, the staff can align the threaded barrel with the water inlet pipe and then screw it in. At this time, due to the action of the external thread and the internal thread, the threaded barrel can be fixed in the water inlet pipe. At this time, the filter barrel can perform primary filtration on the incoming sewage, thereby avoiding clogging of the water inlet pipe. When the filter barrel needs to be removed, the staff only needs to rotate the threaded barrel by turning the rod to screw it out. The utility model uses a threaded connection method to make the installation and disassembly of the filter barrel very simple and quick. The staff only needs to fix or remove the filter barrel by a rotating action, which greatly improves the convenience of operation. The setting of the filter barrel can effectively intercept large particles of impurities, reduce the risk of clogging of the water inlet pipe, and also protect subsequent processing equipment and pipelines from damage by large particles of impurities.

[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1

[0025] See also Figure 1-5 The utility model provides a technical solution: an energy-saving and environmentally friendly sewage filtering and blocking prevention device, comprising a sewage tank 1. The sewage tank 1 is the main part of the whole device and bears the function of storing and treating sewage. A motor 2 is fixedly installed on the top thereof. The motor 2 is used as a power source. Through the stirring rod 3 installed at its output end, the sewage can be effectively stirred to improve the sewage treatment effect. A coarse filter 4 and a fine filter 5 are fixedly installed on the inner wall of the sewage tank 1. These two layers of filter screens constitute the main filtration system of the sewage. The coarse filter 4 is mainly used to intercept large particles of impurities, while the fine filter 5 is used to further filter small particles of impurities to ensure the purification effect of the sewage. The top of the sewage tank 1 is connected with an inlet pipe 6. The inlet pipe 6 is used as the entrance of the sewage. Its design is reasonable and can ensure that the sewage enters the sewage tank 1 smoothly. At the same time, the bottom of the sewage tank 1 is connected with an outlet pipe 7, and the filtered clean water is discharged from the outlet pipe 7. In order to prevent the inlet pipe 6 from being blocked by large foreign matter, a motor 9 is also fixedly installed on the top of the sewage tank 1. The output end of the motor 9 is equipped with an eccentric wheel 10, which is cleverly designed and can drive the connecting plate 11 connected to its surface to do reciprocating motion by its rotation. The side of the connecting plate 11 is rotatably connected with a slide bar 12, which is connected to the water inlet pipe 6 by sliding, thus ensuring that the slide bar 12 can slide freely inside the water inlet pipe 6 and ensuring the stability of the entire device.

[0026] See also Figure 1-5 A mounting plate 13 is fixedly mounted on one end of the slide bar 12, and a cutter 14 is fixedly mounted on the surface of the mounting plate 13. When the motor 9 drives the eccentric wheel 10 to rotate, the connecting plate 11 drives the slide bar 12 to reciprocate on the mounting plate 13, so that the cutter 14 can chop up large foreign objects entering the water inlet pipe 6, effectively preventing the water inlet pipe 6 and the filter from being blocked. In order to ensure the stability of the sewage tank 1, a support leg 15 is fixedly mounted on its bottom end, and the support leg 15 is arranged in a circular shape at the bottom end of the sewage tank 1. Such a design not only ensures the stability of the device, but also makes the entire device more beautiful. At the same time, the cutters 14 are arranged at equal distances on the surface of the mounting plate 13. Such a design can ensure that the cutters 14 are more uniform and efficient when chopping foreign objects.

[0027] Embodiment 2

[0028] See also Figure 3-5, the inner wall of the water inlet pipe 6 is provided with a pollution-blocking mechanism, which includes a threaded barrel 16, and a rotating rod 8 is arranged in a circumferential shape at the top of the threaded barrel 16. The threaded barrel 16 is arranged on the inner wall of the water inlet pipe 6, and its connection method is realized by threaded matching. Specifically, the inner wall of the water inlet pipe 6 is provided with an internal thread, and the outer surface of the threaded barrel 16 is correspondingly provided with an external thread that meshes with the internal thread. This connection method not only ensures the stability of the connection, but also facilitates the installation and removal of the threaded barrel 16. In addition, a filter cartridge 17 is fixedly installed at the bottom end of the threaded barrel 16. The main function of this filter cartridge 17 is to perform primary filtration on the incoming sewage, thereby effectively intercepting large particles of impurities and greatly reducing the risk of clogging of the water inlet pipe 6. At the same time, this design also protects subsequent processing equipment and pipelines, and avoids the damage that may be caused by large particles of impurities. In order to facilitate operation, a rotating rod 8 is also fixedly installed at the top of the threaded barrel 16. The staff can easily rotate the threaded barrel 16 through this rotating rod 8, thereby realizing its installation and removal.

[0029] Working principle: sewage enters through the water inlet pipe 6, and then is filtered through the coarse filter 4 and the fine filter 5 respectively, and finally the purified sewage is discharged from the outlet pipe 7 to complete the processing. At the same time, when the sewage enters the water inlet pipe 6, the motor 9 can drive the eccentric wheel 10 to rotate. When the eccentric wheel 10 rotates, it can drive the connecting plate 11 to reciprocate, and the connecting plate 11 then drives the slide bar 12 to reciprocate, and the slide bar 12 then drives the cutter 14 to move. During the reciprocating movement of the cutter 14, large-volume foreign matter can be chopped up, thereby ensuring that the water inlet pipe 6 is not blocked. The utility model can cut large-volume foreign matter into pieces before the sewage enters the sewage tank 1 through the cutter 14, effectively preventing these foreign matter from clogging the water inlet pipe 6 and the filter, thereby ensuring the continuous and stable operation of the sewage tank 1. Due to the anti-blocking function, the device reduces the frequency of shutdown maintenance caused by blockage, thereby reducing maintenance costs and time costs. At the same time, the motor 9 drives the eccentric wheel 10 and the cutter 14 automatically shreds large-volume foreign objects, avoids the need for manual cleaning of blockages, and improves the degree of automation and work efficiency of sewage treatment. The staff can align the threaded barrel 16 with the water inlet pipe 6 and then screw it into the threaded barrel 16. At this time, due to the action of the external thread and the internal thread, the threaded barrel 16 can be fixed in the water inlet pipe 6. At this time, the filter cartridge 17 can perform primary filtration on the incoming sewage, thereby avoiding clogging of the water inlet pipe 6. When the filter cartridge 17 needs to be removed, the staff only needs to rotate the threaded barrel 16 by rotating the rod 8 to screw it out. The utility model makes the installation and disassembly of the filter cartridge 17 very simple and quick by using a threaded connection method. The staff only needs to fix or remove the filter cartridge 17 by a rotating action, which greatly improves the convenience of operation. The setting of the filter cartridge 17 can effectively intercept large particles of impurities, reduce the risk of clogging of the water inlet pipe 6, and also protect subsequent processing equipment and pipelines from damage by large particles of impurities.
