Description

Technical Field

[0001] The utility model relates to the technical field of wastewater filtration devices, and particularly relates to a filtration device for treating high-concentration organic wastewater. Background Technique

[0002] Organic wastewater is wastewater mainly containing organic pollutants. Organic wastewater is prone to cause water eutrophication and has relatively great harm. The main sources of water pollution are industrial pollution sources, agricultural pollution sources and domestic pollution sources. Among them, industrial wastewater refers to the wastewater, sewage and liquid waste generated in the industrial production process, which contains industrial production materials, intermediate products and products lost with water, as well as pollutants generated in the production process. With the rapid development of industry, the global water resources are increasingly scarce, while the types and quantities of wastewater are increasing rapidly, and the pollution of water bodies is becoming more and more extensive and serious, threatening the health and safety of humans.

[0003] When further precipitating after filtering the wastewater, the residual suspended solids and solid particles in the wastewater cannot be fully dispersed and mixed during the precipitation process, resulting in a slower precipitation speed. Some smaller particles may be suspended in the water and fail to precipitate, reducing the precipitation efficiency. When cleaning the filtration device, the cleaning and maintenance work requires continuous forced entry and exit of the equipment. The lack of a quick-disassembly mechanism may increase the risk of equipment damage, making the maintenance and cleaning work more complicated and possibly requiring more downtime to handle the sedimentation tank, affecting the continuous operation ability and production efficiency of the wastewater treatment system. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a filtration device for treating high-concentration organic wastewater, which can effectively solve the problems that lead to a slower precipitation speed, some smaller particles may be suspended in the water and fail to precipitate, reducing the precipitation efficiency, and making the maintenance and cleaning work more complicated, possibly requiring more downtime to handle the sedimentation tank, affecting the continuous operation ability and production efficiency of the wastewater treatment system.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A filtration device for treating high-concentration organic wastewater, including a treatment tank, the rear side wall of the treatment tank is connected in communication with a sedimentation tank, and a multi-layer stirring structure is arranged inside the sedimentation tank;

[0006] The multi-layer stirring structure includes: a motor, a device box, two second bevel gears, and a leakage pipe. The bottom wall of the motor is fixedly connected to the top wall of the sedimentation tank. The output end of the motor is fixedly connected to a rotating rod. The outer side of the middle part of the rotating rod is fixedly connected with a first bevel gear. The first bevel gear is arranged inside the device box. The two second bevel gears are arranged on the front and rear inner walls of the device box. The first bevel gear meshes with the two second bevel gears. The inside of each of the two second bevel gears is fixedly connected with a connecting rod. The other ends of the two connecting rods are rotatably connected to the front and rear inner walls of the treatment tank. The outer sides of the two connecting rods are fixedly connected with stirring rods. The bottom end of the rotating rod is fixedly connected with a transfer rod. The front and rear ends of the transfer rod are fixedly connected with a first scraper. The bottom end of the rotating rod is fixedly connected with a second scraper. The bottom end of the rotating rod is rotatably connected inside the leakage pipe. The bottom outer side of the leakage pipe is connected with a first diversion plate.

[0007] Further, the first diversion plate is fixedly connected inside the sedimentation tank. The front side wall of the treatment tank is connected with a feed pipe. The bottom of the treatment tank is fixedly connected with a collection box. The inside of the collection box is fixedly connected with a second diversion plate. The rear side wall of the collection box is connected with a sewage discharge pipe.

[0008] Further, a first support plate is fixedly connected inside the treatment tank. A filter cylinder is fixedly connected inside the two first support plates. The bottom of the filter cylinder penetrates and is connected to the bottom wall of the treatment tank. A first baffle is fixedly connected between the middle parts of the treatment tank and the sedimentation tank.

[0009] Further, a water collection tank is communicated with the rear side wall of the sedimentation tank. A second support plate is fixedly connected inside the sedimentation tank. A connecting ring is arranged on the top of the second support plate. A filter box is fixedly connected inside the connecting ring. The bottom outer side of the filter box is arranged inside the second support plate.

[0010] Further, the front and rear side walls of the connecting ring are internally penetrated and connected with a housing. The left and right sides inside the two housings are slidably connected with L-shaped support rods. The other sides of the plurality of L-shaped support rods are fixedly connected with a first spring. The other ends of the plurality of first springs are fixedly connected inside the housing.

[0011] Further, a second spring is fixedly connected in the hole grooves of the two housings. The bottoms of the plurality of second springs are fixedly connected with a second baffle.

[0012] Further, fixing blocks are fixedly connected inside the front and rear side walls of the second support plate. The tops of the two fixing blocks are fixedly connected with clamping blocks. The plurality of clamping blocks are arranged corresponding to the hole grooves of the housing and the L-shaped support rods.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. Through the multi-layer stirring structure provided by the utility model, the problem that the sedimentation speed becomes slow, some smaller particles may suspend in the water and fail to settle, and the sedimentation efficiency is reduced can be solved. The second bevel gear drives the internal connecting rod to rotate on the front and rear inner walls of the treatment tank for support. The rotating connecting rod drives the stirring rod on the outside to remix the preliminarily filtered wastewater with the drug to improve the filtration of the wastewater. After mixing, the generated impurities and sediment will fall into the first deflector. The transfer rod at the bottom end of the rotating rod is used to connect the first scraper and drive the first scraper to rotate. The first scraper scrapes the impurities and sediment falling into the first deflector and scrapes them into the middle of the first deflector to prevent the impurities and sediment from remaining in the dead corner and unable to be treated. When the impurities and sediment reach the middle, the second scraper at the bottom end of the rotating rod will flow the impurities and sediment into the collection box through the leakage pipe for collection, thereby effectively improving the wastewater treatment effect and the operation stability of the system.

[0015] 2. Through the L-shaped support rod, the first spring, the second spring and the second baffle provided, the problem that the maintenance and cleaning work becomes more complicated, and more downtime may be required to handle the sedimentation tank, affecting the continuous operation ability and production efficiency of the wastewater treatment system can be solved. The L-shaped support rod slides inside the housing to squeeze the first spring. When the L-shaped support rod is released, it will achieve the effect of springback and reset. After placing the connecting ring on the upper side wall of the second support plate, the clamping block on the second support plate will enter the hole groove of the housing. After entering the hole groove, the upper side wall of the clamping block will drive the second baffle to squeeze the second spring. When disassembling, it will drive the second baffle to spring back and reset to close the hole groove of the housing to prevent impurities and the like from entering the inside of the housing, thereby effectively reducing the downtime, improving the operation efficiency and reducing the maintenance cost.
