Description

Technical Field

[0001] The present invention relates to the technical field of industrial sewage treatment, and in particular to industrial sewage filtering equipment and a filtering method. Background Art

[0002] Industrial wastewater refers to water containing various chemical substances and biological pollutants generated during industrial production. If it is directly discharged into the environment, it will cause great pollution and harm to water bodies, soil and atmosphere. In order to protect the environment and human health, achieving zero discharge of industrial wastewater has become an important task of current environmental protection work.

[0003] Industrial wastewater contains acids, alkalis, oxidants, and metal substances such as copper, cadmium, mercury, and arsenic, as well as organic poisons such as benzene, ethylene dichloride, and ethylene glycol. If industrial wastewater is not discharged, it will poison aquatic organisms and affect drinking water sources and scenic spots. When organic matter in wastewater is decomposed by microorganisms, it consumes oxygen in the water, affecting the life of aquatic organisms. After the dissolved oxygen in the water is exhausted, the organic matter undergoes anaerobic decomposition, producing unpleasant gases such as hydrogen sulfide and mercaptans, which further deteriorates the water quality.

[0004] When the current sewage treatment equipment is in use, in order to facilitate the filtration of industrial sewage, the industrial sewage is generally discharged into a sedimentation tank, and then a flocculant is added into the sedimentation tank, so that the metal substances in the industrial sewage are flocculated and condensed and precipitated to the bottom of the sedimentation tank. However, after the flocculant is added to the sedimentation tank, the flocculant needs to slowly diffuse in the sewage, which will cause the flocculant to react with the sewage more slowly, resulting in poor sewage treatment effect, and after flocculation, a large amount of sediment and sludge will settle to the bottom of the sedimentation tank, which is inconvenient to clean the sediment and sludge at the bottom of the sedimentation tank.

[0017] In order to solve the above technical problems, the present invention also provides an industrial wastewater filtering method, comprising the following steps:

[0018] Step 1: First, place the flocculants in different placement balls respectively, and seal the placement balls with sealing covers. Then, place the placement cylinder as a whole inside the protective cylinder. Then, clamp the fixed cover on the top of the placement cylinder, and fix the fixed cover and the protective cylinder with fixing screws. After fixing, discharge the industrial wastewater into the placement cylinder through the discharge pipe.

[0019] Step 2: After the placement is completed, the motor works, and the output end rotates to drive the connecting rod on one side to rotate, thereby driving the outer wheel 2 to rotate. Since the wheel 2 is connected to the wheel 3 through the belt 2, it drives the wheel 3 to rotate. The rotation of the wheel 3 drives the guide rod and the worm on one side to rotate, thereby driving the worm wheel to rotate. The rotation of the worm wheel will drive the reciprocating screw 1 located below to rotate. When the reciprocating screw 1 rotates, it will drive the outer stirring wheel to reciprocate up and down inside the placement cylinder to stir the industrial wastewater.

[0020] Step 3: When the stirring wheel moves up and down, during the stirring process, the placement ball inside the placement chamber rotates continuously, and the flocculant inside the placement ball is continuously discharged through the diversion hole. The stirring wheel moves up and down continuously, so that the flocculant can be added to the industrial wastewater at different depths, and the stirring wheel moves up and down continuously to fully mix the flocculant and the industrial wastewater. During the up and down movement of the stirring wheel, the industrial wastewater will pass through the liquid guide groove, the filter hole and the guide groove, so that the industrial wastewater is always in a flowing state, thereby enhancing the flocculation effect;

[0021] Step 4: After the flocculation is completed, open the solenoid valve, and the flocculated industrial wastewater will be discharged through the discharge pipe and discharged into the inner side of the filter cartridge. Since the reciprocating screw 1 at the top is in a state of continuous rotation, it will drive the filter cartridge at the bottom to rotate continuously, so that the clean water after flocculation is thrown out under the action of centrifugal force, and the stains after flocculation will remain inside the filter cartridge. When the filter cartridge rotates continuously, the brush 2 located inside it cleans the inner wall of the filter cartridge.

[0022] Step 5: After the industrial wastewater is filtered through the filter cartridge, the filtered water flows through the connecting pipe to the top of the filter plate placed inside the box. The filter plate continuously filters the water. During the filtering process, when the motor drives the connecting rod on one side to rotate, it will also drive the outer wheel 1 to rotate. Since the wheel 1 and the wheel 4 are connected by the belt 1, the reciprocating screw 2 on one side will be driven to rotate, thereby driving the filter plate located on the outside to reciprocate. During the reciprocating movement, the brush 1 located on the top continuously cleans its surface. The cleaned impurities will flow into the storage cavity through the lower part of the filter plate and be discharged through the discharge port.

[0023] Step six: The clean water after filtering again is pumped by water pump 2 and flows into the storage barrel through infusion pipe 2 for storage. After the industrial wastewater is filtered, water pump 1 located above the storage barrel starts working to pump the stored water through infusion pipe 1 and spray it through the cleaning pipe and high-pressure nozzle to clean the inside of the device.

[0024] Compared with the related art, the industrial sewage filtration equipment provided by the present invention has the following beneficial effects:

[0025] 1. The present invention provides an industrial sewage filtering device, wherein the stirring wheel moves up and down, the placement ball located inside the placement chamber rotates continuously, and the flocculant located inside the placement ball is continuously discharged through the guide hole. The stirring wheel moves up and down continuously, so that the flocculant can be added to the industrial wastewater at different depths, and the stirring wheel moves up and down continuously to fully mix the flocculant and the industrial wastewater. During the up and down movement of the stirring wheel, the industrial wastewater will pass through the liquid guide groove, the filter hole and the guide groove, so that the industrial wastewater is always in a flowing state, thereby enhancing the flocculation effect, thereby improving the diffusion effect of the flocculant and improving the flocculation effect of the industrial wastewater.

[0026] 2. The present invention provides an industrial sewage filtering device. When in use, the reciprocating screw 1 is in a continuous rotating state, driving the filter cartridge at the bottom to rotate continuously, so that the clean water after flocculation is thrown out under the action of centrifugal force, while the sediment and sludge after flocculation remain in the inside of the filter cartridge, and then the fastening bolts are screwed to disengage the fastening bolts from the bottom of the reciprocating screw 1, so that the filter cartridge is taken out, so that the filter cartridge can be taken out as a whole, so that the sediment and sludge inside the filter cartridge can be quickly cleaned.

Placement parts are rotatably arranged inside the three groups of placement chambers 41. The placement parts include placement balls 38. Sealing covers 37 are buckled on the placement balls 38. The diameter of the placement balls 38 is smaller than the diameter of the placement chambers 41. The placement balls 38 rotate inside the placement chambers 41, thereby increasing the fluidity of the placement balls 38 in the industrial wastewater. A number of guide holes are opened on the placement balls 38 and the sealing covers 37, so that the flocculant and industrial wastewater of different depths can be mixed and stirred. A plurality of guide grooves 32 are provided on both sides of the mixing wheel 31, and a filter hole 33 and a drainage hole are provided on both sides of each guide groove 32. The diameter of the filter hole 33 is larger than the diameter of the drainage hole. One side of the guide groove 32 is higher than the other side. The high position of the guide groove 32 is connected with the filter hole 33, and the low position of the guide groove 32 is connected with the drainage hole. When the mixing wheel 31 moves up and down, the water flow can move from the high position of the guide groove 32 to the low position, thereby enhancing the fluidity of the industrial wastewater during the mixing process. The filter hole 33 is connected with the drainage hole through the guide groove 32. A cleaning brush 42 is fixedly installed on the outside of the mixing wheel 31, and one end of the cleaning brush 42 is close to the The inner wall of the placement cylinder 23 is placed, thereby continuously cleaning the inner wall of the placement cylinder 23.

The stirring wheel 31 moves up and down continuously, so that the flocculant can be added to the industrial wastewater at different depths, and the stirring wheel 31 moves up and down continuously to fully mix the flocculant and the industrial wastewater. When the stirring wheel 31 moves up and down, the industrial wastewater will pass through the liquid guide groove 35, the filter hole 33 and the guide groove 32, so that the industrial wastewater is always in a flowing state, thereby enhancing the flocculation effect.

[0043] Furthermore, the top of the reciprocating screw 25 passes through the fixed cover 5 and extends to the outside of the fixed cover 5.

Since the wheel 2 15 is connected to the wheel 3 17 through belt 2 16, the wheel 3 17 is driven to rotate. The rotation of the wheel 3 17 drives the guide rod 18 and the worm 3 on one side to rotate, thereby driving the worm wheel 4 to rotate. The rotation of the worm wheel 4 will drive the reciprocating screw 25 located below to rotate. When the reciprocating screw 25 rotates, it will drive the outer stirring wheel 31 to move back and forth up and down inside the placement cylinder 23 to stir the industrial wastewater.

[0044] Furthermore, discharge holes 34 are provided on both sides of the bottom of the placing cylinder 23, and the discharge holes 34 and the lower hopper 57 are connected to each other.

[0045] Furthermore, the bottom of the reciprocating screw 25 passes through the placement cylinder 23 and extends to the bottom of the placement cylinder 23. A filter cartridge 24 is provided at the bottom of the reciprocating screw 25. A boss 29 is provided at the bottom of the inner side of the filter cartridge 24.

[0046] The working principle of the industrial sewage filtration equipment provided by the present invention is as follows:

[0047] The first step: place the flocculants in different placement balls 38 respectively, and use the sealing cover 37 to seal the placement balls 38, then place the placement cylinder 23 as a whole on the inner side of the protective tube 1, and then clamp the fixing cover 5 on the top of the placement cylinder 23, and fix the fixing cover 5 and the protective tube 1 with fixing screws. After fixing, discharge industrial wastewater into the placement cylinder 23 through the discharge pipe. After the industrial wastewater is discharged, the motor 13 works, and the output end rotates to drive the connecting rod 12 on one side to rotate, thereby driving the outer rotating wheel 2 15 to rotate. Since the rotating wheel 2 15 is connected to the rotating wheel 3 17 through the belt 2 16, it drives the rotating wheel 3 17 to rotate. The rotation of the rotating wheel 3 17 drives the guide rod 18 and the worm 3 on one side to rotate, thereby driving the worm wheel 4 to rotate. The rotation of the worm wheel 4 will drive the reciprocating screw 25 located below to rotate. When the reciprocating screw 25 rotates, it will drive the outer stirring wheel 31 to move back and forth up and down inside the placement cylinder 23 to stir the industrial wastewater.

[0048] Step 2: When the stirring wheel 31 moves up and down, during the stirring process, the placement ball 38 located inside the placement chamber 41 rotates continuously, and the flocculant located inside the placement ball 38 is continuously discharged through the guide hole. The stirring wheel 31 moves up and down continuously, so that the flocculant can be added to the industrial wastewater at different depths. The stirring wheel 31 moves up and down continuously to fully mix the flocculant and the industrial wastewater. When the stirring wheel 31 moves up and down, the industrial wastewater will pass through the liquid guide groove 35, the filter hole 33 and the guide groove 32, so that the industrial wastewater is always in a flowing state, thereby enhancing the flocculation effect.

[0049] Step 3: After the flocculation is completed, the solenoid valve 58 is opened, and the flocculated industrial wastewater will be discharged through the discharge pipe 59 and discharged into the inner side of the filter cartridge 24. Since the upper reciprocating screw 25 is in a continuous rotation state, it will drive the filter cartridge 24 at the bottom to rotate continuously, so that the clean water after flocculation is thrown out under the action of centrifugal force, and the stains after flocculation will remain in the inside of the filter cartridge 24. When the filter cartridge 24 rotates continuously, the brush 60 located on its inner side cleans the inner wall of the filter cartridge 24. After the flocculation wastewater is filtered, the placement cylinder 23 is taken out, and then the fastening bolt 26 is screwed to disengage the fastening bolt 26 from the bottom of the reciprocating screw 25, thereby taking out the filter cartridge 24, so that the filter cartridge 24 can be taken out as a whole, thereby quickly cleaning the sediment and sludge inside the filter cartridge 24.

The stirring wheel 31 moves up and down continuously, so that a flocculant can be added to industrial wastewater at different depths, and the stirring wheel 31 moves up and down continuously to fully mix the flocculant and the industrial wastewater. During the up and down movement of the stirring wheel 31, the industrial wastewater will pass through the liquid guide groove 35, the filter hole 33 and the guide groove 32, so that the industrial wastewater is always in a flowing state, thereby enhancing the flocculation effect, thereby improving the diffusion effect of the flocculant and improving the flocculation effect of the industrial wastewater.

[0058] Third embodiment:

[0059] This embodiment provides an industrial wastewater filtering method, comprising the following steps:

[0060] Step 1: First, the flocculants are placed inside different placement balls 38, and the placement balls 38 are sealed with sealing covers 37. Then, the placement cylinder 23 is placed as a whole inside the protective cylinder 1. Then, the fixing cover 5 is clamped on the top of the placement cylinder 23, and the fixing cover 5 and the protective cylinder 1 are fixed by fixing screws. After fixing, the industrial wastewater is discharged into the placement cylinder 23 through the discharge pipe;

[0061] Step 2: After the placement is completed, the motor 13 works, and the output end rotates to drive the connecting rod 12 on one side to rotate, thereby driving the outer rotating wheel 2 15 to rotate. Since the rotating wheel 2 15 is connected to the rotating wheel 3 17 through the belt 2 16, the rotating wheel 3 17 is driven to rotate. The rotating wheel 3 17 drives the guide rod 18 and the worm 3 on one side to rotate, thereby driving the worm wheel 4 to rotate. The rotation of the worm wheel 4 will drive the reciprocating screw 1 25 located below to rotate. When the reciprocating screw 1 25 rotates, it will drive the outer stirring wheel 31 to reciprocate up and down inside the placement cylinder 23 to stir the industrial wastewater.

[0062] Step 3: When the stirring wheel 31 moves up and down, during the stirring process, the placement ball 38 located inside the placement chamber 41 rotates continuously, and the flocculant located inside the placement ball 38 is continuously discharged through the guide hole. The stirring wheel 31 moves up and down continuously, so that the flocculant can be added to the industrial wastewater at different depths, and the stirring wheel 31 moves up and down continuously to fully mix the flocculant and the industrial wastewater. During the up and down movement of the stirring wheel 31, the industrial wastewater will pass through the liquid guide groove 35, the filter hole 33 and the guide groove 1 32, so that the industrial wastewater is always in a flowing state, thereby enhancing the flocculation effect;

[0063] Step 4: After the flocculation is completed, the electromagnetic valve 58 is opened, and the flocculated industrial wastewater is discharged through the discharge pipe 59 and discharged into the inner side of the filter cartridge 24. Since the reciprocating screw 1 25 at the top is in a continuous rotation state, the filter cartridge 24 at the bottom is driven to rotate continuously, so that the clean water after flocculation is thrown out under the action of centrifugal force, and the flocculated stains are left inside the filter cartridge 24. When the filter cartridge 24 rotates continuously, the brush 2 60 located inside it cleans the inner wall of the filter cartridge 24.

[0064] Step 5: After the industrial waste water is filtered by the filter cartridge 24, the filtered water flows through the connecting pipe 22 to the top of the filter plate 50 placed inside the box 9, and the filter plate 50 continuously filters the water. During the filtering process, when the motor 13 drives the connecting rod 12 on one side to rotate, it will also drive the outer wheel 14 to rotate. Since the wheel 14 and the wheel 4 30 are connected by the belt 18, the reciprocating screw 2 51 on one side will be driven to rotate, thereby driving the filter plate 50 located on the outside to reciprocate. During the reciprocating movement, the brush 1 48 located on the top continuously cleans its surface, and the cleaned impurities will flow into the interior of the storage chamber 45 through the lower part of the filter plate 50 and be discharged through the discharge port 10;

[0065] Step six: The clean water after the second filtration is extracted by water pump 2 43 and flows into the storage barrel 11 through infusion pipe 2 44 for storage. After the industrial waste water is filtered, water pump 1 21 located above the storage barrel 11 starts to work, extracts the stored water through infusion pipe 1 20, and sprays it through cleaning pipe 2 and high-pressure nozzle to clean the inside of the device.

An industrial wastewater filtering method using the industrial wastewater filtering equipment as claimed in claim 8, characterized in that: The following steps are involved: Step 1: First, place the flocculants in different placement balls respectively, and seal the placement balls with sealing covers. Then, place the placement cylinder as a whole inside the protective cylinder. Then, clamp the fixed cover on the top of the placement cylinder, and fix the fixed cover and the protective cylinder with fixing screws. After fixing, discharge the industrial wastewater into the placement cylinder through the discharge pipe. Step 2: After the placement is completed, the motor works, and the output end rotates to drive the connecting rod on one side to rotate, thereby driving the outer wheel 2 to rotate. Since the wheel 2 is connected to the wheel 3 through the belt 2, it drives the wheel 3 to rotate. The rotation of the wheel 3 drives the guide rod and the worm on one side to rotate, thereby driving the worm wheel to rotate. The rotation of the worm wheel will drive the reciprocating screw 1 located below to rotate.

When the filter cartridge rotates continuously, the brush 2 located inside it cleans the inner wall of the filter cartridge. Step 5: After the industrial wastewater is filtered through the filter cartridge, the filtered water flows through the connecting pipe to the top of the filter plate placed inside the box. The filter plate continuously filters the water. During the filtering process, when the motor drives the connecting rod on one side to rotate, it will also drive the outer wheel 1 to rotate. Since the wheel 1 and the wheel 4 are connected by the belt 1, the reciprocating screw 2 on one side will be driven to rotate, thereby driving the filter plate located on the outside to reciprocate. During the reciprocating movement, the brush 1 located on the top continuously cleans its surface. The cleaned impurities will flow into the storage cavity through the lower part of the filter plate and be discharged through the discharge port. Step six: The clean water after filtering again is pumped by water pump 2 and flows into the storage barrel through infusion pipe 2 for storage.
