Description

Technical Field

[0001] The invention relates to the technical field of xanthate wastewater treatment, and in particular to a xanthate wastewater treatment device and process. Background Art

[0002] Xanthate wastewater is produced in the process of using xanthate (also known as sodium ethyl xanthate or sodium butyl xanthate) as a flotation agent. During the mineral flotation process, xanthate is added to the ore pulp to improve the selective adsorption and separation efficiency of the target mineral. After flotation, the remaining ore pulp contains not only unreacted xanthate, but may also include other chemicals and impurities. These residues together constitute xanthate wastewater.

[0003] In order to effectively treat this kind of wastewater, existing equipment usually includes sedimentation tanks, flotation machines, sand filters, reverse osmosis devices and ultrafiltration devices. Among them, flotation machines are widely used due to their high efficiency in removing suspended matter. Their working principles are as follows: first, the wastewater is flocculated to make fine particles condense into larger flocs; then tiny bubbles are injected into the wastewater, which attach to the flocs and make them float to the water surface to form a scum layer. The cleaning equipment then collects and treats the scum. This process can not only significantly reduce the suspended matter content in the wastewater, but also provide better water inlet conditions for subsequent treatment steps.

[0004] However, there is a problem when existing flotation machines produce bubbles: bubbles are prone to merge and form unstable large bubbles, which not only reduces the stability of the scum layer, but also may cause secondary dispersion, causing the aggregated flocs to be redispersed into the water, thereby affecting the scum cleaning effect and overall processing efficiency. Summary of the invention

[0009] Furthermore, the driving component includes: a second driving member, the second driving member being disposed on the connecting frame; A connecting plate fixedly connected to the second driving member, the connecting plate being fixedly connected with sliding rods having the same number as the sealing shells, the sliding rods passing through the adjacent fixed shells and being slidably connected thereto, and one side of the sliding rod located in the adjacent fixed shell being fixedly connected to the adjacent sealing shell; A plurality of salvaging components, the number of which is the same as that of the mobile shells, and which are respectively arranged in adjacent mobile shells for salvaging sediments; A plurality of deceleration components, the number of which is the same as that of the moving shells, are respectively arranged in adjacent sealing shells to slow down the moving speed of the sliding shells.

[0010] Further, the salvage assembly includes: The swinging blades distributed in a ring array are all rotatably connected to the adjacent moving shells; The number of the fixed blades distributed in the annular array is the same as that of the swinging blades, and they are all fixedly connected to the adjacent moving shells, and the swinging blades are in contact with the adjacent fixed blades.

[0011] Furthermore, the fixed blade is fixedly connected with a symmetrically distributed third guide block, and the third guide block is provided with two inclined surfaces.

[0012] Furthermore, the swinging blades are fixedly connected with gears, the sliding shell is fixedly connected with a ring array of racks, the racks in the ring array correspond to the swinging blades one by one, and the gears are meshed with adjacent racks.

[0013] Furthermore, the deceleration component includes: A liquid containing shell, fixedly connected to the adjacent sealing shell; A sealing member is slidably connected in the adjacent liquid containing shell, the side of the sealing member away from the adjacent liquid containing shell is fixedly connected to the adjacent sliding shell, a spring is arranged between the liquid containing shell and the adjacent sealing member, the sealing member is provided with symmetrically distributed liquid through holes, and one of the symmetrically distributed liquid through holes is provided with a check valve.

[0014] Furthermore, the deceleration assembly also includes: a fixed column, fixedly connected in the adjacent liquid storage shell, the fixed column passes through the adjacent liquid holes in the adjacent sealing member, and the diameter of the fixed column is smaller than the diameter of the adjacent liquid hole, and the length of the fixed column is smaller than the distance that the sealing member moves in the adjacent liquid storage shell.

[0015] A process adopted by a xanthate wastewater treatment device comprises the following steps: Step 1: When wastewater needs to be treated, the gas injection port of the external gas injection device and the liquid injection port of the external liquid injection device are connected to the gas guide shell and the liquid injection pipe respectively, and the liquid discharge port of the external clear liquid discharge device is connected to the first guide block, thereby completing the preparation action for wastewater treatment; Step 2: After the preparation for wastewater treatment is completed, the wastewater, flocculant and coagulant aid of the required volume are injected into the flotation tank. During this process, the wastewater, flocculant and coagulant aid in the flotation tank are stirred by an agitator; Step 3: The pollutants in the wastewater are treated with flocculants and coagulants to form flocs, and the gas ejected from the air guide shell (16) changes the gas into bubbles and drives the flocs to move upward, so that the flocs float on the liquid surface to form scum, and the scum is scraped into the material container shell by the cleaner; Step 4: When the floccules float toward the liquid surface, they pass between the first guide block and the second guide block, and the large bubbles are treated by a water jet sprayed from the liquid outlet of the liquid spray pipe; Step 5: When sediment appears in the first guide block, the telescopic end of the second driving member drives the sliding rod, the sealing shell and the moving shell to move synchronously through the connecting plate, and the moving shell drives the third guide block to move until it contacts the scum layer, and the third guide block drives the flocculant and the bubbles it carries to the surroundings; Step 6: After the gas outlet shell moves to contact with the first guide block, the first guide block and the movable shell are relatively displaced, so that the swinging blades swing and the hydraulic oil in the liquid storage shell flows through the liquid through hole; Step 7: After the sliding shell is attached to the inner side of the moving shell, the gas in the fixed shell enters the gas outlet shell through the sliding shell and is discharged from it. When the gas discharged from the gas outlet shell contacts the wastewater, bubbles are formed. The bubbles float and drive the deposited flocculants to float upward synchronously. Step 8: When the telescopic end of the second driving member is reset, the sealing shell and the moving shell move upward synchronously, so that the fixed blades salvage the surrounding flocculants; Step 9: When the sealing shell and the movable shell are above the liquid surface, the fixed fan blades are reset and swung to the basic state; Step 10: When wastewater treatment is no longer required, turn off all electrical equipment.

[0016] The beneficial effects of the present invention are as follows: in order to solve the problem that bubbles are easily merged into large bubbles when the flotation machine produces bubbles, the present invention uses a high-speed water jet to directly impact the bubbles, so that the large bubbles are actively broken, the proportion of large bubbles is reduced, and the size of the bubbles in the flotation process is ensured to be more consistent, thereby improving the overall processing efficiency; In order to solve the problem that when the scraper plate in the flotation machine contacts the scum layer, the contact between the two easily causes the bubbles in the scum layer to burst, causing part of the flocculants in the scum layer to fall off, the present invention adopts a method of salvaging at the bottom of the pool to "fish out" the deposited flocculants, so that the deposited flocculants can float on the liquid surface again and can be effectively removed; In view of the fact that the foam generated during the treatment of xanthate wastewater will overflow into other equipment and affect the treatment process of other equipment, and the existing method of spraying defoaming agents to remove foam will cause the problem of secondary pollution of wastewater, the present invention aims to provide a more environmentally friendly foam control method. Specifically, a physical defoaming method is adopted to simulate the method of inserting a "rod" into the foam to destroy the surface tension of the foam, and when the rod is pulled out, the pull-out position is actively changed to increase the foam treatment efficiency during the reciprocating movement of the rod. This method not only avoids the secondary pollution problem caused by chemical defoaming agents, but also improves the effect of foam treatment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] Although the present invention may be described with respect to a particular application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those of ordinary skill in the art will recognize that terms such as: upward, downward, etc. are used to describe the drawings and do not represent limitations on the scope of the present invention as defined by the appended claims. Any numerical designations such as: first or second are merely exemplary and are not intended to limit the scope of the present invention in any way.

[0020] In order to solve the problem that bubbles are easily merged into large bubbles when the flotation machine is making bubbles, the present invention innovatively introduces high-speed water jet technology, which precisely impacts the large bubbles and cleverly causes them to quickly break and transform into fine and uniform small bubbles.

[0021] Embodiment 1: A xanthate wastewater treatment device, such as Figure 1-Figure 5As shown, it includes: an air flotation tank 10; an agitator 11, which is arranged on one side of the air flotation tank 10; a cleaner 12, which is arranged on the other side of the air flotation tank 10, a first guide block 13 and a second guide block 14 are fixedly connected in the air flotation tank 10, and there is a gap between the first guide block 13 and the second guide block 14; a material holding shell 15, which is fixedly connected to one side of the air flotation tank 10 close to the cleaner 12, and the cleaner 12 is located between the material holding shell 15 and the second guide block 14; an air guide shell 16, which is fixedly connected to the air flotation tank 10, and the first guide The opposite sides of the block 13 and the second guide block 14 are fixedly connected with a liquid spray pipe 17, and the liquid spray pipe 17 is provided with a plurality of liquid outlets. The water jets sprayed from the liquid outlets on the liquid spray pipe 17 impact the surrounding large bubbles; the air supply component is arranged on the second guide block 14, and is used to supply gas into the wastewater. The two liquid spray pipes 17 are both located above the air guide shell 16, and the plurality of liquid outlets on the two liquid spray pipes 17 are staggered. There is a gap between the water jets sprayed from the liquid outlets on the two liquid spray pipes 17.

[0022] In the above scheme, the stirrer 11 is used to stir the wastewater in the flotation tank 10, and the cleaner 12 is used to clean the scum layer in the flotation tank 10. The bubbles between the first guide block 13 and the second guide block 14 are gathered into large bubbles and then pass through the two spray pipes 17. The water jets sprayed from the liquid outlets in the two spray pipes 17 impact the large bubbles (the kinetic energy of the water flow is instantly transferred to the bubble membrane, exceeding the maximum stress that the bubble membrane can withstand. This external force destroys the surface tension balance of the bubble and causes the bubble membrane to rupture), reducing the particle size of the large bubble, so that the large bubble is divided into multiple small bubbles, thereby increasing the capture capacity of the flocculant during the flotation process (the capture capacity refers to the ability of the bubble to attach to and carry the flocculant to float to the liquid surface to form scum during the flotation process).

[0023] like Figure 4 and Figure 6-Figure 11 As shown, the air supply component includes: a first driving member 20, which is arranged on the second guide block 14; a connecting frame 21, which is fixedly connected to the first driving member 20; a plurality of fixed shells 22, which are all fixedly connected to the connecting frame 21, the fixed shells 22 are fixedly connected and connected with an air supply pipe, the fixed shells 22 are slidably connected with a sealing shell 23, and a one-way valve is arranged in the sealing shell 23; a plurality of movable shells 24, which are the same in number as the fixed shells 22 and are respectively fixedly connected and connected with adjacent sealing shells 23, the movable shells 23 are slidably connected with a sliding shell 25 connected thereto, and the sliding shell 25 is fixedly connected and connected with an air outlet shell 26; a driving component, which is arranged on the connecting frame 21, and is used to drive all the fixed shells 22 to move.

[0024] In the above scheme, the first driving member 20 is an electric slide rail, an electric slider is arranged in the first driving member 20, the connecting frame 21 is fixedly connected to the electric slider in the first driving member 20, there are two fixed shells 22 in the present invention, and the specific number can be adjusted according to actual conditions, the fixed shell 22 is located above the liquid surface of the wastewater, when the sealing shell 23 moves downward, the one-way valve in the sealing shell 23 remains closed, and when the sealing shell 23 moves upward, the one-way valve in the sealing shell 23 is in an open state, the cross-section of the sliding shell 25 is an isosceles trapezoid, and the lower bottom of the isosceles trapezoid of the sliding shell 25 is located on the upper side, the sliding shell 25 is used to drive away the flocs around the sliding shell 25 to ensure the integrity of the flocs, and looking from top to bottom, the air outlet shell 26 is cross-shaped or can be a cross-shaped, and the specific shape can be adjusted according to actual conditions, and adjusting the shape of the air outlet shell 26 is used to adjust its air outlet position and air outlet range.

[0025] like Figure 6-Figure 8 As shown, the driving assembly includes: a second driving member 30, which is arranged on the connecting frame 21; a connecting plate 31, which is fixed to the second driving member 30, and the connecting plate 31 is fixed with sliding rods 32 whose number is the same as the sealing shell 23, and the sliding rods 32 pass through the adjacent fixed shell 22 and are slidably connected thereto, and the sliding rods 32 are located on one side of the adjacent fixed shell 22 and are fixedly connected to the adjacent sealing shell 23; a plurality of salvaging assemblies, which are the same as the number of the moving shells 24 and are respectively arranged in the adjacent moving shells 24 for salvaging sediments; a plurality of deceleration assemblies, which are the same as the number of the moving shells 24 and are respectively arranged in the adjacent sealing shells 23 for slowing down the moving speed of the sliding shell 25.

[0026] In the above scheme, the second driving member 30 is an electric push rod, the telescopic end of the second driving member 30 is fixedly connected to the connecting plate 31, the sliding rod 32 is sealed and slidably connected to the adjacent fixed shell 22, and the lower end of the sliding rod 32 is fixedly connected to a U-shaped frame fixedly connected to the adjacent sealing shell 23.

[0027] like Figure 8-Figure 10 As shown, the salvage assembly includes: swinging blades 40 distributed in a ring array, all of which are rotatably connected to adjacent moving shells 24; fixed blades 41 distributed in a ring array, the number of which is consistent with the swinging blades 40, and all of which are fixed to adjacent moving shells 24, the swinging blades 40 are in contact with adjacent fixed blades 41, the fixed blades 41 are fixed with symmetrically distributed third guide blocks 42, the third guide blocks 42 are provided with two inclined surfaces, the swinging blades 40 are fixed with gears 50, the sliding shell 25 is fixed with racks 51 in a ring array, the racks 51 in the ring array correspond one-to-one with the swinging blades 40, and the gears 50 are meshed with adjacent racks 51.

[0028] In the above scheme, the swinging blades 40 are provided with two symmetrically distributed arc surfaces. When the movable shell 24 and the sliding shell 25 are relatively displaced, the swinging blades 40 of the annular array and the fixed blades 41 of the annular array form a full circle, and the third guide block 42 is used to drive the surrounding flocculants.

[0029] like Figure 9-11 As shown, the deceleration assembly includes: a liquid containing shell 60, fixedly connected to the adjacent sealing shell 23; a sealing member 61, slidably connected in the adjacent liquid containing shell 60, the side of the sealing member 61 away from the adjacent liquid containing shell 60 is fixedly connected to the adjacent sliding shell 25, a spring is arranged between the liquid containing shell 60 and the adjacent sealing member 61, the sealing member 61 is provided with symmetrically distributed liquid through holes 62, one of the symmetrically distributed liquid through holes 62 is provided with a check valve, and the deceleration assembly also includes: a fixed column 63, fixedly connected in the adjacent liquid containing shell 60, the fixed column 63 passes through the adjacent liquid through holes 62 in the adjacent sealing member 61, and the diameter of the fixed column 63 is smaller than the diameter of the adjacent liquid through hole 62, and the length of the fixed column 63 is smaller than the distance moved by the sealing member 61 in the adjacent liquid containing shell 60.

[0030] In the above scheme, the seal 61 is fixedly connected to the adjacent sliding shell 25 through a connecting rod. When the seal 61 moves upward, the check valve in the liquid hole 62 is in an open state. Conversely, when the seal 61 moves downward, the check valve in the liquid hole 62 is in a closed state.

[0031] Working principle: When it is necessary to use this device to treat xanthate wastewater, the user first connects the gas injection port of the external gas injection device and the liquid injection port of the external liquid injection device to the air guide shell 16 and the liquid spray pipe 17 respectively, and then the user connects the liquid discharge port of the external clear liquid discharge device to the middle and upper side of the first guide block 13 (the external clear liquid discharge device is used to discharge the clean water after treatment).

[0032] After completing the installation of the external gas injection equipment and the external clear liquid discharge equipment, the user injects wastewater into the right side of the flotation tank 10 (i.e., below the agitator 11). During the wastewater injection process, the user injects flocculants and coagulants in a capacity that meets the required work volume. Then, the agitator 11 stirs the wastewater, flocculants and coagulants on the right side of the flotation tank 10 to increase the mixing efficiency of the flocculants, coagulants and wastewater. As the wastewater is continuously injected, the wastewater flows upward between the first guide block 13 and the second guide block 14.

[0033] When the liquid level of the wastewater reaches the required liquid level for work (after reaching the required liquid level for work, it does not exceed the upper side of the first guide block 13), the injection ports of the external gas injection device and the external liquid injection device inject gas and liquid into the air guide shell 16 and the liquid spray pipe 17 respectively. During the exhaust process of the air guide shell 16, the gas contacts the wastewater to form bubbles and moves upward. The bubbles in the flotation tank 10 move upward between the first guide block 13 and the second guide block 14. The pollutants in the wastewater are treated with flocculants and coagulants to form floccules. The floccules contact the gas in the flotation tank 10 and move upward between the first guide block 13 and the second guide block 14 (the above working principle is consistent with the working principle of the existing flotation machine).

[0034] In the process of bubbles driving flocs to move upward between the first guide block 13 and the second guide block 14, the bubbles come into contact with adjacent bubbles to form large bubbles. The flocs and the large bubbles come into contact with the water jet sprayed from the spray port of the spray pipe 17. The water jet sprayed from the spray port of the spray pipe 17 breaks the large bubbles and reduces the particle size of the bubbles.

[0035] The bubbles drive the floccules to enter the upper side of the first guide block 13 through between the first guide block 13 and the second guide block 14, and float toward the liquid surface under the action of the bubbles carrying the floccules, thereby forming a scum layer, which is then scraped into the material holding shell 15 by the cleaner 12, and the scum layer is collected by the material holding shell 15.

[0036] In the prior art, when the scraper plate contacts the scum layer (the scraper plate corresponds to the cleaner 12 in the present invention), the liquid surface is disturbed and the scum layer is pressed. If the bubbles in the scum layer are broken at this time, the scum layer formed by the flocculants will separate, causing part of the flocculants to fall to the bottom of the pool (corresponding to the bottom of the flotation pool 10 in the present invention), resulting in the flocculants not being effectively removed and settling to the bottom of the pool, reducing the removal efficiency of the flotation machine for suspended matter and affecting the overall treatment effect. Therefore, the present invention adopts the following statement to solve the above problem: The problem raised is as follows: first, the air outlet of the external air supply device is connected to the air supply pipes on all the fixed shells 22, the first driving member 20 first drives the connecting frame 21 to move to the required working position, and then the external air supply device supplies gas into the fixed shell 22 through the air supply pipe. At this time, the second driving member 30 drives its telescopic part to drive the connecting plate 31 to move downward, and the connecting plate 31 drives the two sealed shells 23 to move downward synchronously through the two sliding rods 32, so that the sealed shell 23 drives the movable shell 24 and its accessories to move into the flotation tank 10.

[0037] When the movable shell 24 drives all the swinging blades 40 and the third guide block 42 thereon to move until the sliding shell 25 contacts the scum layer in the flotation tank 10, a gentle squeezing force is applied to the scum layer on the lower side of the third guide block 42 through the two inclined surfaces on the lower side of the third guide block 42, so that the bubbles in the scum layer will not be directly punctured during the movement of the third guide block 42, but the flocculant and the bubbles carried by it will be driven to the surroundings to ensure the integrity of the bubbles in the scum layer. When the swinging blades 40 contact the scum layer, the arc-shaped surfaces thereon will not directly puncture the bubbles in the scum layer during the movement of the swinging blades 40, but will drive the bubbles to the surroundings.

[0038] When the air outlet shell 26 moves with the moving shell 24 to the lower side of the air outlet shell 26 and contacts the upper side of the first guide block 13, the sealing shell 23 continues to drive the moving shell 24 to slide downward. At this time, the moving shell 24 and the sliding shell 25 are relatively displaced. During the sliding process of the sliding shell 25, all the racks 51 and the seal 61 thereon are driven to move upward synchronously relative to the moving shell 24 (the spring is squeezed during the movement of the seal 61). During the movement of the rack 51, it meshes with the adjacent gear 50, so that the gear 50 drives the swinging blade 40 to rotate along the adjacent moving shell 24. During the movement of the seal 61, the hydraulic oil in the liquid holding shell 60 flows through the two liquid holes 62 on the seal 61. The check valve in one of the liquid holes 62 is in an open state at this time. During the movement of the seal 61, the fixed column 63 is gradually inserted into the other liquid hole 62.

[0039] When the upper side of the sliding shell 25 is fitted with the inner side of the moving shell 24, the swinging blade 40 has rotated 90° and is in contact with the adjacent fixed blade 41, and all the swinging blades 40 and the fixed blades 41 on the moving shell 24 have formed a "full circle" when viewed from top to bottom, the telescopic end of the second driving member 30 stops moving, the upper side of the sliding shell 25 is fitted with the inner side of the moving shell 24, and the gas pressure in the fixed shell 22 gradually increases. When the pressure of the gas in the fixed shell 22 is sufficient to break through the restriction of the one-way valve in the sealing shell 23, the gas enters the sealing shell 23, and enters the moving shell 24 and the sliding shell 25 from the sealing shell 23, and is then discharged from the gas outlet shell 26. The gas discharged from the gas outlet shell 26 forms bubbles when it contacts the wastewater. During the upward floating process, the bubbles contact the flocculant precipitated on the upper side of the first guide block 13, thereby driving the flocculant upward, so that the deposited flocculants can float on the liquid surface and can be effectively removed.

[0040] After treating the deposited flocculants for a period of time, the moving direction of the telescopic part of the second driving member 30 is switched, so that the telescopic part of the second driving member 30 changes from contracting downward to extending upward. During the process of the telescopic part of the second driving member 30 extending upward, the two sealing shells 23 are driven to reset upward through the connecting plate 31 and the sliding rod 32, and the gas outlet shell 26 is no longer in contact with the upper side of the first guide block 13. At this time, the spring in the liquid holding shell 60 drives the sealing member 61 to move downward, and the sliding shell 25 is driven to move synchronously during the movement of the sealing member 61. At this time, the sealing member 61 The check valve in the liquid through hole 62 on one side of the upper part of the sealing member 61 is in a closed state, and the liquid through hole 62 on the other side of the upper part of the sealing member 61 is blocked by the fixed column 63. As the diameter of the fixed column 63 is smaller than the diameter of the adjacent liquid through hole 62, the amount of liquid in the liquid containing shell 60 flowing through the adjacent liquid through hole 62 is reduced, thereby realizing the slow reset of the sealing member 61 and the sliding shell 25. The slow reset of the sliding shell 25 drives the adjacent gear 50 to reset and rotate through the rack 51, thereby achieving the effect of reducing the swing speed of the gear 50 and the adjacent swinging blade 40.

[0041] When the sealing shell 23 and the moving shell 24 move upward, the flocculants that are in contact with the bubbles and deposited on the upper side of the first guide block 13 are re-salved upward through the "full circle" formed by all the swinging blades 40 and the fixed blades 41 on the moving shell 24, thereby increasing the speed of the flocculants moving upward, thereby improving the efficiency of the entire wastewater treatment.

[0042] When the sealing shell 23 drives all the swinging blades 40 and the fixed blades 41 thereon to move to above the liquid surface in the first guide block 13 through the movable shell 24, the sealing member 61 has moved to the fixed column 63 and no longer blocks the adjacent liquid through hole 62, so that the flow rate of the liquid through hole 62 changes instantly, thereby making the reset speed of the sealing member 61 faster than the previous speed. During the reset process of the sealing member 61, the gear 50 is driven to rotate by the sliding shell 25 and all the racks 51 thereon, and the gear 50 then drives the adjacent swinging blades 40 to rotate rapidly. During the rapid rotation of the swinging blades 40, the flocculants thereon are thrown to the scum layer to prevent the flocculants from sticking to the swinging blades 40, while making the flocculants that have settled to the bottom contact with the scum layer again, thereby improving the efficiency of wastewater treatment.

[0043] When the moving shell 24 and its attached parts move to Figure 7 After reaching the state in the middle, the second driving member 30 stops working. At this time, the user controls the external air supply equipment to stop injecting gas into the fixed shell 22. When the deposited flocculants need to be treated again, the above process can be repeated. After completing the treatment of the wastewater, all the above-mentioned electrical equipment can be turned off.

[0044] Embodiment 2: Based on Embodiment 1, the present invention can also achieve the following actions and effects: Working principle: In the process of treating xanthate wastewater, the generation of foam is a common phenomenon. The specific reasons are as follows: xanthate itself is a surfactant, and its molecular structure has a unique amphiphilicity: one end is a hydrophilic group, and the other end is a hydrophobic group. This structure enables the xanthate molecule to be adsorbed on the gas-liquid interface and significantly reduce the surface tension. Therefore, when xanthate exists in wastewater, it is like a "foam maker" that can easily promote and stabilize a large number of bubbles; in the process of treating xanthate wastewater, excessive foam will cause it to overflow into other treatment equipment, and the foam entering other treatment equipment will affect the working efficiency and treatment effect of this equipment. The existing method of removing foam is usually to spray a defoaming agent into the foam, but the defoaming agent will contact the wastewater after removing the foam, which will cause the chemical components in the defoaming agent to remain in the wastewater, increase the content of organic matter or harmful substances in the treated water, and cause secondary pollution. In view of the above problems, the present invention is explained through the following statements: After the wastewater in the flotation tank 10 generates foam, the second driving member 30 drives its telescopic part to pull the connecting plate 31 downward, and the connecting plate 31 drives the fixed shell 22 to move downward through the sliding rod 32. The fixed shell 22 drives all the swinging blades 40, the fixed blades 41 and the third guide block 42 thereon to move downward through the moving shell 24. When the two inclined surfaces of the third guide block 42 contact the foam, the two inclined surfaces of the third guide block 42 separate the foam, destroying the surface tension of the foam (this foam is caused by the xanthate wastewater itself during the treatment process), so that the foam near this part gradually dissipates by itself.

[0045] After the foam is destroyed, the second driving member 30 drives its telescopic part to push the connecting plate 31 upward, and the connecting plate 31 drives the fixed shell 22 to move upward through the sliding rod 32. In this process, the first driving member 20 drives the connecting frame 21 to move forward or backward, so that the connecting frame 21 drives the second driving member 30 to move, and changes the position where the movable shell 24 moves out, so that the movable shell 24 can also process the foam in other parts when it moves out. Figure 6 After the foam is in the state, the processing of the foam is completed. Repeat the above steps when using it again.

[0046] Embodiment 3: Based on embodiment 2, Figure 1-Figure 11 As shown, the present invention also provides a process used in a xanthate wastewater treatment device, comprising the following steps: Step 1: When wastewater needs to be treated, the gas injection port of the external gas injection device and the liquid injection port of the external liquid injection device are connected to the gas guide shell 16 and the liquid injection pipe 17 respectively, and the liquid discharge port of the external clear liquid discharge device is connected to the first guide block 13, thereby completing the preparation action for wastewater treatment; Step 2: After the preparation for wastewater treatment is completed, the wastewater, flocculant and coagulant aid of the required volume are injected into the flotation tank 10. During this process, the wastewater, flocculant and coagulant aid in the flotation tank 10 are stirred by the stirrer 11; Step 3: The pollutants in the wastewater are treated with flocculants and coagulants to form flocs, which are contacted with the gas ejected from the gas guide shell 16, so that the gas changes into bubbles and drives the flocs to move upward, so that the flocs float on the liquid surface to form scum, and the cleaner 12 scrapes the scum into the material holding shell 15; Step 4: When the floccules float toward the liquid surface, they pass between the first guide block 13 and the second guide block 14, and the large bubbles are treated by the water jet sprayed from the liquid outlet of the liquid spray pipe 17; Step 5: When sediment appears in the first guide block 13, the telescopic end of the second driving member 30 drives the sliding rod 32, the sealing shell 23 and the moving shell 24 to move synchronously through the connecting plate 31, and the moving shell 24 drives the third guide block 42 to move until it contacts the scum layer, and the third guide block 42 drives the flocculant and the bubbles it carries to the surroundings; Step 6: After the gas outlet housing 26 moves to contact the first guide block 13, the first guide block 13 and the movable housing 24 are relatively displaced, so that the swinging blades 40 swing, and the hydraulic oil in the liquid storage housing 60 flows through the liquid through hole 62; Step 7: After the sliding shell 25 is attached to the inner side of the moving shell 24, the gas in the fixed shell 22 enters the gas outlet shell 26 through the sliding shell 25 and is discharged therefrom. When the gas discharged from the gas outlet shell 26 contacts the wastewater, bubbles are formed, and the bubbles float and drive the deposited flocculants to float upward synchronously; Step 8: When the telescopic end of the second driving member 30 is reset, the sealing shell 23 and the moving shell 24 move upward synchronously, so that the fixed blades 41 salvage the surrounding flocculants; Step nine: When the sealing shell 23 and the movable shell 24 are above the liquid surface, the fixed blade 41 is reset and swung to the basic state; Step 10: When wastewater treatment is no longer required, turn off all electrical equipment.

[0047] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
