[0001] The utility model relates to the technical field of domestic sewage treatment, in particular to a strong filtration domestic sewage treatment device. Background Art

[0002] Domestic sewage refers to the wastewater generated in people's daily lives, mainly from residential buildings and public buildings. Before entering the subsequent chemical sewage treatment system, domestic sewage usually needs to be initially forced to be filtered at the source.

[0003] This is because domestic sewage contains a large amount of suspended particulate impurities. If these impurities are not filtered out in time, they may damage subsequent chemical sewage treatment equipment and cause pipe blockage. Therefore, it is necessary to use a source forced filtration device for domestic sewage.

[0004] At present, the existing forced filtration device for domestic sewage at the source has an insignificant forced filtration effect on the source of domestic sewage, which greatly reduces the damage caused by unfiltered suspended particulate impurities to subsequent chemical sewage treatment equipment and its normal use.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] A disinfection storage box 31 and a disinfection pump 33 are provided on the top frame 3, and a disinfection pipe 32 and a disinfection injection pipe 34 are connected to the disinfection pump 33;

[0028] The motor 7 is provided with a motor shaft 71, the motor shaft 71 is provided with a sleeve 72 and a main shaft 8, the main shaft 8 is provided with a stirring blade 81, the stirring blade 8 is provided with a mixing hole 82, and the drain pipe 11 is connected to the joint of the external chemical sewage treatment equipment, which is the existing technology and is not drawn.

[0029] The grid filter 12 is arranged on the left side of the sand filter cartridge 13 and is vertically inserted into the strong filter box 1. The grid filter 12 and the sand filter cartridge 13 can filter out suspended particulate impurities in domestic sewage.

[0030] The activated carbon filter 14 is arranged on the right side of the sand filter cartridge 13 and is vertically inserted into the strong filter box 1. The activated carbon filter 14 can adsorb and deodorize domestic sewage.

[0031] The right end of the strong reflux pipe 61 is connected to the strong filtration box 1, and the strong circulation pipe 62 is connected to the strong filtration box 1. Combined with the strong circulation pump 6, forced circulation filtration and adsorption deodorization of domestic sewage for a period of time are achieved.

[0032] The sealing plate 41 is vertically inserted into the strong filter box 1, and the top of the sealing plate 41 is fixed to the telescopic rod of the cylinder 4. The sealing plate 41 is made of rubber material to ensure vertical sliding while ensuring the blocking of domestic sewage and the sealing effect between the strong filter box 1.

[0033] The top frame 3 is an L-shaped structure as a whole. The sewage extraction pipe 51 passes through the top frame 3 and is connected to the source storage box 21. The source storage box 21 is pre-stored with domestic sewage.

[0034] The top of the main shaft 8 is a cone-shaped structure and is vertically aligned with the disinfection injection pipe 34. When the disinfectant is injected vertically, it will fall on the top of the main shaft 8 and flow downward evenly along the cone-shaped main shaft 8, further improving the comprehensive contact and mixing with domestic sewage.

[0035] There are four stirring blades 81 arranged in a circle, and the mixing holes 82 pass through the stirring blades 81. When the stirring blades 81 rotate at high speed, the mixed disinfectant and domestic sewage will pass through each mixing hole 82 to achieve a mixed flow stirring effect.

[0036] The sleeve 72 is fixedly arranged on the bottom side wall of the strong filter box 1, and the sleeve 72 is squeezed and sleeved with the motor shaft 71. The sleeve 72 is made of NBR nitrile rubber and has excellent wear-resistant elastic sealing properties, ensuring the rotation of the motor shaft 71 while ensuring the sealing degree.

[0037] A replenishing pipe 22 is provided at the top of the source storage box 21 to facilitate the subsequent replenishment of domestic sewage.

[0038] Working method: Start the sewage injection pump 5 for a period of time and then shut it down. A certain amount of domestic sewage is extracted from the source storage box 21 through the sewage extraction pipe 51 and injected into the strong filter box 1 through the sewage injection pipe 52. At this time, a certain amount of domestic sewage will be filtered out of suspended particulate impurities by the grille filter 12 and the sand filter cartridge 13 respectively, and then will be adsorbed and deodorized by the activated carbon filter 14. Due to the obstruction of the baffle 41, the strong circulation pump 6 is started at the same time, and the domestic sewage can be recirculated and pumped into the strong filter box 1 through the strong circulation pipe 62 and the strong reflux pipe 61 for forced circulation filtration, adsorption and deodorization. The strong circulation pump 6 can be stopped after being started for a period of time, so as to realize forced circulation filtration of domestic sewage at the source for a period of time, and then the suspended particulate impurities in the domestic sewage are comprehensively and effectively filtered and deodorized, thereby improving the overall quality of the forced filtration effect of the source of domestic sewage, and avoiding the damage and normal use of the subsequent chemical sewage treatment equipment caused by the suspended particulate impurities that have not been filtered out.

[0039] In addition, after a certain amount of domestic sewage is forced to circulate, filter and deodorize, the disinfection pump 33 and the motor 7 can be started. The disinfection pump 33 injects the disinfectant pre-stored in the disinfection storage box 31 into the strong filtration box 1 through the disinfection pipe 32 and the disinfection injection pipe 34. At the same time, the motor 7 drives the stirring blade 81 to rotate at high speed through the main shaft 8. Combined with the mixing hole 82, the domestic sewage and the disinfectant can be effectively stirred and mixed, and the domestic sewage after forced filtration can be further fully and effectively mixed and stirred to sterilize, thereby eliminating pathogens in the domestic sewage and greatly improving the sterility of the domestic sewage when it is input into the chemical sewage treatment equipment in the later stage.

[0040] After the stirring and sterilization is completed, the cylinder 4 can be started to drive the baffle 41 to move upward and position, and the drain pipe 11 can be opened at the same time to discharge the domestic sewage after forced circulation filtration and stirring and sterilization and transport it to the subsequent chemical sewage treatment equipment.

[0041] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
