Description

Technical Field

[0001] The utility model belongs to the technical field of filtering structures, and in particular relates to a filtering structure for treating domestic sewage. Background Art

[0002] Domestic sewage refers to wastewater from residential, commercial and industrial activities, which contains various organic, inorganic and microorganisms. Domestic sewage usually includes toilet wastewater, bathing wastewater, kitchen wastewater, etc. When domestic sewage is discharged and treated, a filtering structure is needed to intercept some larger particles of garbage in the sewage to ensure that the sewage discharge will not affect the environment.

[0003] However, when personnel in this field actually use it, they find that the filtering mechanism of most existing sewage pools is of the fence type. When intercepting some garbage in the sewage, it is necessary to manually remove the fence from the sewage and clean it, which is inconvenient for employees to use. In addition, the sewage naturally discharged from the existing sewage pool is easy to settle in the sewage pool, and some garbage mixed in the sewage will also settle at the same time, which is inconvenient for effective cleaning. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a filtering structure for treating domestic sewage, which has the advantage of convenient cleaning of garbage on the filter net bag plate.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a filtering structure for treating domestic sewage, comprising a sewage pool, a water inlet pipe is arranged on one side of the sewage pool, a water outlet pipe is arranged on the other side of the sewage pool, a crushing mechanism is arranged inside the sewage pool, and a filtering mechanism is arranged inside the sewage pool.

[0006] Preferably, the filtering mechanism includes a filter net bag plate, which is arranged inside the sewage pool, and connecting plates are fixedly connected to both sides of the filter net bag plate, and threaded plates are fixedly connected to the outsides of the two connecting plates, and two correspondingly distributed fixing frames are fixedly connected to the outside of the sewage pool, and the bottoms of the two fixing frames are fixedly connected to a second motor, and the output end of the second motor is fixedly connected to a threaded rod, and the threaded rod is threadedly connected to the inside of the threaded plate.

[0007] Preferably, the bottoms of the two threaded rods are fixedly connected to limiting round blocks, and the limiting round blocks are made of stainless steel.

[0008] Preferably, the inner sides of the two connecting plates are fixedly connected to limiting blocks, and limiting grooves are provided on both sides of the sewage pool, and the limiting blocks are slidably connected in the limiting grooves.

[0009] Preferably, the crushing mechanism includes two rotating shaft rods, both of which are rotatably connected to the inside of the sewage pool, and the outsides of the two rotating shaft rods are fixedly connected with a plurality of evenly distributed crushing leaves, and the outsides of the two rotating shaft rods are fixedly connected with transmission wheels, and the outsides of the two transmission wheels are rotatably connected with transmission belts, and the outside of one of the rotating shaft rods is fixedly connected with a second bevel tooth.

[0010] Preferably, a mounting plate is fixedly connected to the outside of the sewage pool, a first motor is fixedly connected to the top of the mounting plate, a first bevel gear is fixedly connected to the output end of the first motor, and the first bevel gear is meshingly connected with the second bevel gear.

[0011] Preferably, two correspondingly distributed retaining plates are fixedly connected to the top of the mounting plate, and the two retaining plates are located on both sides of the first motor.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. By starting the two second motors, the threaded rods fixed to the output ends of the two second motors begin to rotate, and then drive the threaded plate connected by the thread to move upward, and at the same time drive the fixed connecting plate to start moving. When the connecting plate moves, the limit block fixed on the inner side slides in the limit groove, making the movement smoother and more stable, and then drive the filter net bag plate fixed between the two connecting plates to start moving upward, and stop rising when the filter net bag plate is completely exposed to the water surface. At this time, the garbage on the filter net bag plate can be easily cleaned. Through this structure, the intercepted garbage can be easily cleaned, which is more convenient for users to use.

[0014] 2. By starting the first motor, the first bevel tooth fixed to the output end of the first motor starts to rotate, and then drives the meshing second bevel tooth to start rotating, and at the same time drives the fixed rotating shaft rod to rotate. When the rotating shaft rod rotates, the externally fixed transmission wheel starts to rotate, and the externally transferred transmission belt can drive another transmission wheel to start rotating. At this time, the two rotating shaft rods rotate at the same time, and then drive several externally fixed crushing leaves to rotate at the same time, so as to stir the interior and crush the garbage to prevent the garbage from settling and being difficult to handle.
