Description

Technical Field

[0001] This utility model relates to the field of separation and recovery technology of hydrogen-containing silicone oil from organosilicon wastewater, specifically to an integrated device for separation and recovery of hydrogen-containing silicone oil from organosilicon wastewater. Background Technology

[0002] Organosilicon materials, with their excellent resistance to high and low temperatures, weathering, electrical insulation, and physiological inertness, have found widespread application in many fields such as electronics, construction, chemicals, and medicine. However, the production process of organosilicon generates a large amount of wastewater containing hydrogen-containing silicone oil. If this wastewater is discharged directly into the environment without proper treatment, it will not only cause serious pollution to water bodies, soil, and other ecological elements, but also mean that the valuable hydrogen-containing silicone oil resources contained within it will be wasted. How to effectively treat organosilicon production wastewater and recover the hydrogen-containing silicone oil has become an important problem that urgently needs to be solved in the organosilicon industry.

[0003] In existing technologies, hydrogen-containing silicone oil in wastewater is recycled using various separation and recycling equipment. Since the wastewater contains a large amount of sludge and impurities, it needs to be filtered before recycling. Traditional filtration equipment filters directly through a filter screen. After long-term use, the filter screen is easily clogged and needs to be disassembled and cleaned frequently, which is time-consuming and labor-intensive. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide an integrated device for separating and recovering hydrogen-containing silicone oil from organosilicon wastewater. It can quickly separate and clean the filtered impurities, and is easy to operate, saving time and effort.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: an integrated device for separating and recovering hydrogen-containing silicone oil from organosilicon wastewater, including a separation and recovery tank, a support frame fixedly connected to the upper end of the separation and recovery tank, a filter tank fixedly connected to the upper end of the support frame, an ultrafiltration membrane assembly provided between the separation and recovery tank and the filter tank, a fixed cover fixedly connected to the upper end of the filter tank, an inlet pipe fixedly connected to the upper end of the fixed cover, a filter screen cylinder rotatably connected to one end of the fixed cover extending into the filter tank, a rotating mechanism for driving the filter screen cylinder to rotate provided inside the filter tank; a sludge pump fixedly connected to the upper end of the fixed cover, a sludge suction pipe fixedly connected to the input end of the sludge pump extending to the center of the filter screen cylinder, at least one guide pipe arranged in a circular array fixedly connected to one side of the sludge suction pipe, a sludge suction hood fixedly connected to the other end of the guide pipe, the end of the sludge suction hood slidingly connected to the inner wall of the filter screen cylinder, and a cleaning brush provided inside the sludge suction hood.

[0006] As an improvement, the cleaning brush includes a rotating shaft rotatably connected inside the sludge suction hood, with evenly arranged brushes fixedly connected to the outer wall of the rotating shaft, the upper end of the sludge suction hood rotating to connect a gear that drives the rotating shaft to rotate, and a gear ring meshing with the gear fixedly connected to the inner wall of the fixed cover.

[0007] As an improvement, the rotating mechanism includes a driven pulley fixedly sleeved on the outer wall of the filter cylinder, a driving pulley rotatably connected inside the filter box, a first motor for driving the driving pulley to rotate fixedly connected to the upper end of the filter box, and the driving pulley and the driven pulley connected by a transmission belt.

[0008] As an improvement, the separation and recycling box is equipped with a feeding hopper on one side and a stirrer inside.

[0009] As an improvement, the stirrer includes a stirring shaft, with stirring blades fixedly connected to the outer wall of the stirring shaft, and a second motor for driving the stirring blades to rotate is fixedly connected to the upper end of the separation and recovery tank.

[0010] As an improvement, a feed hopper is fixedly connected to the bottom surface of the filter box, and a flow guide pump is provided between the feed hopper and the ultrafiltration membrane module.

[0011] The advantages of this invention compared to existing technologies are as follows: Large particulate impurities in wastewater can be initially filtered through the filter screen cylinder, and then the wastewater is further filtered through the ultrafiltration membrane module. The filtered wastewater enters the separation and recovery tank, where chemicals are added for separation and recovery. When it is necessary to clean the impurities inside the filter screen cylinder, the rotating mechanism is activated to drive the filter screen cylinder to rotate, throwing the impurities inside the filter screen cylinder to the side wall. At the same time, the sludge pump is activated, and the sludge suction hood sucks the impurities from the side wall of the filter screen cylinder. The operation is convenient, time-saving, and labor-saving. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1 to 4 As shown, an integrated device for separating and recovering hydrogen-containing silicone oil from organosilicon wastewater includes a separation and recovery tank 1. A support frame 3 is fixedly connected to the upper end of the separation and recovery tank 1. A filter box 2 is fixedly connected to the upper end of the support frame 3. An ultrafiltration membrane assembly 4 is provided between the separation and recovery tank 1 and the filter box 2. A feed hopper is fixedly connected to the bottom surface of the filter box 2. A flow guide pump 23 is provided between the feed hopper and the ultrafiltration membrane assembly 4. A feeding hopper 21 is provided on one side of the separation and recovery tank 1, and an agitator is provided inside. The agitator includes a stirring shaft 18. Stirring blades 19 are fixedly connected to the outer wall of the stirring shaft 18. A second motor 20 is fixedly connected to the upper end of the separation and recovery tank 1 to drive the stirring blades 19 to rotate.

[0019] A fixed cover 5 is fixedly connected to the upper end of the filter box 2. An inlet pipe 22 is fixedly connected to the upper end of the fixed cover 5. A filter screen cylinder 6 is rotatably connected to one end of the fixed cover 5 inside the filter box 2. A rotating mechanism for driving the filter screen cylinder 6 to rotate is provided inside the filter box 2. The rotating mechanism includes a driven pulley 14 fixedly sleeved on the outer wall of the filter screen cylinder 6. A driving pulley 15 is rotatably connected inside the filter box 2. A first motor 16 for driving the driving pulley 15 to rotate is fixedly connected to the upper end of the filter box 2. The driving pulley 15 and the driven pulley 14 are connected by a transmission belt 17.

[0020] A sludge pump 7 is fixedly connected to the upper end of the fixed cover 5. A sludge suction pipe 8 extending to the center of the filter cylinder 6 is fixedly connected to the input end of the sludge pump 7. At least one guide pipe 9 arranged in a circular array is fixedly connected to one side of the sludge suction pipe 8. A sludge suction cover 10 is fixedly connected to the other end of the guide pipe 9. The end of the sludge suction cover 10 is slidably connected to the inner wall of the filter cylinder 6. A rotating shaft 11 is rotatably connected inside the sludge suction cover 10. A uniformly arranged brush 13 is fixedly connected to the outer wall of the rotating shaft 11. The upper end of the sludge suction cover 10 rotates to connect to a gear 12 that drives the rotating shaft 11 to rotate. A gear ring 24 that meshes with the gear 12 is fixedly connected to the inner wall of the fixed cover 5.

[0021] In practical use, wastewater is added into the filter cylinder 6 through the inlet pipe 22, so that large particles of impurities remain in the filter cylinder 6. The remaining wastewater is pumped into the ultrafiltration membrane module 4 by the diversion pump 23 for further filtration. After filtration, it enters the separation and recovery tank 1, and the reagent is added through the feeding port.

The drive pulley 15 drives the driven pulley 14 to rotate, and the driven pulley 14 drives the filter cylinder 6 to rotate at high speed, throwing the sludge and impurities inside the filter cylinder 6 to the side wall. At the same time, the inner wall of the filter cylinder 6 rotates along the sludge suction hood 10, causing the impurities to be scraped into the sludge suction hood 10. The impurities are then extracted through the guide pipe 9 and the suction pipe 8. While the filter cylinder 6 is rotating, the gear 12 is driven to roll along the gear ring 24 on the inner wall of the fixed cover 5, causing the gear 12 to drive the rotating shaft 11 to rotate. The rotating shaft 11 drives the brush 13 to clean the inner wall of the filter cylinder 6, preventing the filter cylinder 6 from becoming clogged and affecting the filtration effect.
