Description

Technical Field

[0001] This utility model relates to the field of fluorosilicone oil technology, and in particular to an ultrafiltration reverse osmosis staged water treatment device for fluorosilicone oil processing wastewater. Background Technology

[0002] Fluorosilicone oil is a trifluoropropyl-modified organosilicon compound that combines the high and low temperature resistance of methyl silicone oil (operating temperature range of -60~200℃) with the oil resistance, solvent resistance and chemical stability of fluorides. Its low surface tension and hydrophobic and oleophobic properties make it excellent in the fields of lubricants, mold release agents, and defoamers. In the production process of fluorosilicone oil, it is necessary to treat the production wastewater.

[0003] A search revealed a Chinese patent (application number "202421395789.0") disclosing "an industrial wastewater ultrafiltration reverse osmosis tiered water treatment device." This tiered water treatment device includes an industrial wastewater tank, a pretreatment tank, a reverse osmosis treatment tank, and an ultrafiltration membrane tank. Limiting plates are installed at both ends of the inner wall of the pretreatment tank, and a filter frame is positioned between the limiting plates. A connecting block is fixed to one side of the filter frame. A through slot is provided inside one side of the pretreatment tank. A sealing plate is fixed to one side of the connecting block, a handle is fixed to one side of the sealing plate, and a sealing block is fixed to the other side of the sealing plate. A curved pipe is installed on one side of the bottom of the pretreatment tank. However, during use, the filter frame cannot be quickly disassembled and cleaned. Impurities in the wastewater easily clog the filter frame, preventing it from effectively filtering the wastewater, resulting in low practicality. Utility Model Content

[0004] This utility model provides an ultrafiltration reverse osmosis staged water treatment device for fluorosilicone oil processing wastewater, which solves the problem of the staged water treatment device proposed in the prior art, which cannot quickly disassemble and clean the filter frame when treating industrial wastewater, and the impurities in the wastewater easily clog the filter frame, resulting in the filter frame not being able to filter the wastewater sufficiently and having low practicality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A staged ultrafiltration and reverse osmosis water treatment device for fluorosilicone oil processing wastewater includes an ultrafiltration tower, a primary reverse osmosis treatment tank, and a secondary reverse osmosis treatment tank. A mixing mechanism is provided on one side of the ultrafiltration tower, comprising a mixing cylinder, a fixed cylinder welded to the inner wall of one side of the mixing cylinder, and spiral guide vanes welded to the inner wall of the mixing cylinder. A pretreatment mechanism is provided on one side of the mixing cylinder, comprising a pretreatment cylinder with a drain pipe fixed to its bottom inner wall, a drain pipe fixed to the lower inner wall of one side of the pretreatment cylinder, and a cylinder bolted to the outer wall of the top of the pretreatment cylinder. The pretreatment cylinder is equipped with a filter assembly, which includes a support cylinder with several drain outlets on its lower outer wall, several fixed blocks with arc-shaped structures welded to the top outer wall of the support cylinder, and several arc-shaped filter plates with their upper parts penetrating and slidingly sleeved on the outer wall of the cylinder cover. The mixing cylinder is equipped with a sewage discharge assembly below it, which includes a tee pipe screwed to the lower outer wall of the sewage discharge pipe, an adjusting screw penetrating and screwed to the inner wall of the tee pipe, and a sealing plug fixed to the top outer wall of the adjusting screw.

[0007] Preferably, a wastewater pipe is fixed on the upper inner wall of one side of the mixing drum, and a dosing pipe is fixed on the inner wall of the top of the mixing drum. A guide pipe is connected to the outer wall of one end of the mixing drum via a flange.

[0008] The above scheme involves transporting production wastewater into the mixing drum through a wastewater pipe. The production wastewater flows along the fixed drum and guide vanes. At the same time, the dosing pipe is connected to the flow control valve to control the delivery speed and flow rate of the flocculant. The flocculant and the production wastewater come into contact and flow together spirally along the guide vanes, thus mixing the flocculant and the production wastewater.

[0009] Preferably, an installation pipe is fixed on the upper inner wall of one side of the pretreatment cylinder, and the installation pipe is connected to the outer wall of one side of the guide pipe through a flange.

[0010] Preferably, the support cylinder is welded to the inner wall of the bottom of the pretreatment cylinder, and a semi-circular mounting groove is opened on the outer wall of both ends of several fixing blocks. The two ends of several filter plates are respectively slidably sleeved in the mounting grooves on two adjacent fixing blocks. Fixing plates are fixed on the outer wall of the top of several filter plates, and several fixing plates are respectively connected to the outer wall of the top of the cylinder cover by bolts.

[0011] Preferably, the sealing plug is slidably sleeved inside the support cylinder, a flushing pipe is screwed onto the inner wall of one end of the tee pipe, and a discharge pipe is screwed onto the end of the tee pipe away from the flushing pipe.

[0012] The above method involves conveying production wastewater into the pretreatment cylinder via a guide pipe. Multiple filter plates filter impurities and sediments in the wastewater within the pretreatment cylinder. Wastewater is then pumped out from the ring formed by the multiple filter plates and fixed blocks via a pumping pipe. Simultaneously, one end of the drain pipe is closed via a valve. Rotating the adjusting screw causes the sealing plug to rise, allowing the wastewater and sediment at the bottom of the pretreatment cylinder to enter the three-way pipe. The flushing pipe delivers clean water and transports the wastewater and sediment from the three-way pipe to the discharge pipe. Pulling the fixed plate and removing the filter plate allows for cleaning of the filter plate.

[0013] Preferably, the top of the pumping pipe is connected to a delivery pipe via a flange, and one end of the drain pipe is connected to the outer wall of one end of the delivery pipe via a flange. One end of the delivery pipe is connected to a first booster pump via a flange, and one end of the first booster pump is connected to the interior of the ultrafiltration tower via a water supply pipe. The delivery pipe is fixed on the inner wall of the top of the ultrafiltration tower, and one end of the delivery pipe is fixed on the inner wall of the top of the first-stage reverse osmosis treatment tank. One side of the first-stage reverse osmosis treatment tank is connected to a second booster pump via a water supply pipe, and one end of the second booster pump is connected to the interior of the second-stage reverse osmosis treatment tank via a water supply pipe. The first-stage reverse osmosis treatment tank is connected to the second-stage reverse osmosis treatment tank via a return pipe.

[0014] The above scheme involves ultrafiltration treatment of production wastewater using an ultrafiltration tower. The wastewater then enters a primary reverse osmosis treatment tank for primary reverse osmosis filtration. The wastewater after primary reverse osmosis filtration enters a secondary reverse osmosis treatment tank for secondary reverse osmosis filtration. A portion of the concentrated wastewater is then returned to the primary reverse osmosis treatment tank.

[0015] The beneficial effects of this utility model are as follows:

[0016] The guide pipe transports production wastewater into the pretreatment cylinder. Multiple sets of filter plates filter impurities and sediments in the wastewater within the pretreatment cylinder. Wastewater is then pumped out from the ring formed by the multiple sets of filter plates and fixed blocks through the pumping pipe. Simultaneously, one end of the drain pipe is closed by a valve. Rotating the adjusting screw causes the sealing plug to rise, allowing the wastewater and sediment at the bottom of the pretreatment cylinder to enter the tee pipe. The flushing pipe delivers clean water and transports the wastewater and sediment in the tee pipe to the discharge pipe. Pulling the fixed plate and removing the filter plate allows for easy cleaning of the filter plate. This process quickly removes filtered impurities and sediments, preventing clogging and improving practicality. Attached Figure Description
