Description

Technical Field

[0001] The present invention relates to the technical field of waste phosphoric acid stock solution treatment, and particularly to an oil and slag removal device for chemical polishing waste phosphoric acid stock solution. Background Art

[0002] Chemical polishing phosphoric acid stock solution is mainly composed of phosphoric acid, often containing sulfuric acid and nitric acid. It has low cost, can easily make metals shiny, has a wide range of applicable materials and a wide process operation range. However, it will produce harmful gases, has a short solution life and is difficult to adjust the concentration. After being discarded, in order to avoid polluting the subsequent treatment system, affecting the recovery effect and reducing environmental hazards, and to prevent blocking pipelines and equipment and avoid affecting water quality and treatment effect, it is necessary to remove oil and slag from chemical polishing waste phosphoric acid stock solution.

[0003] In the oil and slag removal process, first, the stock solution is diluted to a concentration range of 20%-30%, and the pH value of the system is adjusted by adding lime milk to create a suitable chemical environment for the subsequent action of the medicaments. Subsequently, a coagulant and a flocculant are added in sequence, and their hydrolysis characteristics are utilized to promote the formation and aggregation of colloids, enabling the flocs to gradually grow. Finally, the efficient separation of the flocs and the liquid phase is achieved by means of a flotation device.

[0004] Traditional flotation devices usually only have a single dissolved air tank. During operation, the air compressor automatically performs start-stop operations according to the signals fed back by the pressure sensor in the dissolved air tank. When the pressure in the dissolved air tank drops to the preset lower limit value, the air compressor starts to supplement air. However, during the pressure drop stage, due to the decrease in dissolved air efficiency, the amount of bubble generation decreases accordingly, which will not only have a negative impact on the oil and slag removal effect, making it difficult for the treated water quality to meet the expected standards, but also significantly reduce the working efficiency of oil and slag removal, prolong the operation cycle of the entire process flow, and increase production costs.

[0005] Therefore, it is necessary to provide an oil and slag removal device for chemical polishing waste phosphoric acid stock solution, aiming to solve the above problems. Summary of the Invention

[0006] The main purpose of the present invention is to provide an oil and slag removal device for chemical polishing waste phosphoric acid stock solution, which can effectively solve the problems in the background art.

A filter screen is fixedly connected between the partition five and the device main body.

[0013] As a further improvement of the above solution, a foam scraping component is arranged at the top of the device main body. The foam scraping component includes a scraper and a motor. Two transmission rollers are rotatably connected to the top of the device main body. A transmission is formed between the two transmission rollers and the scraper. Transmission belts are uniformly fixedly connected to the outer side of the scraper. One of the transmission rollers penetrates through the device main body and is fixedly connected to the output shaft of the motor.

[0014] As a further improvement of the above solution, the communication mechanism further includes pistons symmetrically and slidably connected inside the dissolved air tank. Inert gas is stored between the pistons and the dissolved air tank.

[0015] As a further improvement of the above solution, sealing rings are symmetrically and fixedly connected inside the three-way pipe, the movable seat is rotatably connected between the two sealing rings, and a water pump is fixedly installed on the outer side of the connecting pipe.

[0016] As a further improvement of the above solution, a sealing seat is fixedly connected to the top of the dissolved air tank, and the connecting rod is rotatably connected to the sealing seat.

[0017] As a further improvement of the above solution, a pressure port is provided inside the pressure seat, and a three-way groove is fixedly communicated with the top of the pressure seat.

Subsequently, the flocs are filtered by the filter screen, and the filtrate enters the partition chamber, and the filtrate enters the dissolved air tank through the connecting pipe. At the same time, the pressurizing mechanism performs a pressurizing operation on the phosphoric acid stock solution in the dissolved air tank. When the pressure reaches a predetermined value, the opening and closing mechanism is started, and the movable seat is driven to be installed in the reverse direction through the pressure seat, so as to realize the switching of the two dissolved air spaces in the dissolved air tank, effectively solving the problem that the oil removal and slag removal treatment efficiency is reduced and the treatment quality declines due to the start and stop of the air compressor in the traditional single dissolved air space mode.

[0021] 2. The second spring uses the clamping block in the sliding seat to seal one air flotation pipe with a sealing plate, and the other is inside the mounting seat to open the corresponding air flotation pipe. When the pressure in the sealed air flotation pipe is too high, the sealing plate is pushed down to squeeze the clamping block, and the clamping block slides down along the guide rod. The slider drives the sealing plate to be received in the mounting seat. At the same time, this sealing plate drives another sealing plate to seal another mounting seat through the connecting frame and the pressure seat, realizing the alternating opening and closing of the two air flotation pipes.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figures 1 to 11 as shown, the present invention provides an embodiment:

[0037] An oil and slag removal device for waste phosphoric acid stock solution in chemical polishing, comprising a device main body 1. A partition component 2 is arranged inside the device main body 1. A dilution chamber, a mixing chamber, a flotation chamber and a partition chamber are arranged in the device main body 1 through the partition component 2. A flotation component 3 is arranged outside the device main body 1. The flotation component 3 includes an air dissolution tank 31 fixedly installed on the top of the device main body 1 through a bracket 32. The air dissolution tank 31 is communicated with the partition chamber through a communication mechanism 33. The communication mechanism 33 is symmetrically communicated with the flotation chamber through two flotation tubes 36. An opening and closing mechanism 35 is arranged at the top of the two flotation tubes 36. A pressurization mechanism 37 is arranged at the top of the air dissolution tank 31. An air flotation base 38 is fixedly communicated between the two flotation tubes 36;

[0038] The communication mechanism 33 includes fixing plates 333 symmetrically and fixedly connected inside the air dissolution tank 31. A three-way pipe 334 is fixedly connected between the two fixing plates 333. The three-way pipe 334 is communicated with the partition chamber through a connecting pipe 331. An activity seat 337 is rotatably connected inside the three-way pipe 334. An L-shaped hole is opened inside the activity seat 337. A connecting rod 336 is fixedly connected to the top of the activity seat 337. A gear 3351 is fixedly connected to the top of the connecting rod 336;

[0039] The opening and closing mechanism 35 includes a mounting seat 351 fixedly connected to the tops of the two flotation tubes 36. Sealing plates 352 are symmetrically and slidably connected inside the mounting seat 351. Connecting frames 358 are symmetrically and fixedly connected to the outer sides of the sealing plates 352;

[0040] The pressurization mechanism 37 includes a pressurization seat 371 slidably connected to the top of the air dissolution tank 31. A rack 3352 is fixedly connected to the bottom of the pressurization seat 371. The gear 3351 meshes with the rack 3352.

[0041] In actual application of this embodiment, as Figures 1 to 3 shown, the waste phosphoric acid stock solution first enters the dilution chamber inside the device main body 1 and is diluted to an appropriate concentration in the dilution chamber. Subsequently, the stock solution flows into the mixing chamber, and lime milk is added in the mixing chamber to adjust the pH value, creating suitable conditions for the subsequent agents to play a role. Then, a coagulant and a flocculant are added to promote the formation of flocs of impurities and oil in the stock solution;

[0042] AsFigures 1 to 4 As shown, the original liquid after forming flocs enters the air flotation chamber. At the same time, the phosphoric acid original liquid in the separation chamber enters the dissolved air tank 31 through the connection mechanism 33, and the pressurization mechanism 37 starts to work, sending high-pressure gas into the dissolved air tank 31 to pressurize the phosphoric acid original liquid in the dissolved air tank 31.

[0043] As Figure 4 、 Figure 6 、 Figure 8 、 Figure 9 and Figure 11 As shown, when the pressure in the dissolved air tank 31 reaches the specified value, the opening and closing mechanism 35 comes into play. The pressure in the dissolved air tank 31 is transmitted to the air flotation tube 36 through the connection mechanism 33. When the pressure in one of the air flotation tubes 36 is too high, it pushes the sealing plate 352 towards the inside of the mounting seat 351 through the inclined surface of the sealing plate 352, realizing the storage of the sealing plate 352 in the mounting seat 351. At this time, this air flotation tube 36 opens. At the same time, this sealing plate 352 is linked with the pressurizing seat 371 through the connecting frame 358, driving the sealing plate 352 in the mounting seat 351 at the top of the other air flotation tube 36 to seal this air flotation tube 36. In this way, the alternating opening and closing of the two air flotation tubes 36 is realized. The dissolved phosphoric acid original liquid enters the air flotation chamber through the opened air flotation tube 36. In the air flotation chamber, the bubbles generated by dissolved air combine with the flocs, causing the flocs to adsorb oil stains and impurities and float to the liquid surface. The separation of the flocs from the liquid is realized through devices such as the air flotation base 38, thus completing the process of removing oil and slag from the waste phosphoric acid original liquid for chemical polishing;

[0044] As Figure 6 、 Figure 7 、 Figure 9 and Figure 10 As shown, when the connecting frame 358 drives the pressurizing seat 371 to slide on the top of the dissolved air tank 31, the rack 3352 fixedly connected to its bottom drives the engaged gear 3351 to rotate, and then the connecting rod 336 and the movable seat 337 connected below the gear 3351 rotate in the tee pipe 334, adjusting the connection state between the dissolved air tank 31 and the separation chamber to facilitate the cooperation of the two air flotation tubes 36 to complete the alternation of the two dissolved air spaces and ensure the efficiency of removing oil and slag.

[0045] As Figures 1 to 3 As shown, the separation component 2 includes the partition plate one 21, the partition plate two 22, the partition plate three 23, the partition plate four 24, and the partition plate five 25. The dilution chamber is composed of the partition plate two 22 and the equipment main body 1. The mixing chamber is composed of the partition plate two 22, the equipment main body 1, and the partition plate four 24. The air flotation chamber is composed of the partition plate four 24, the equipment main body 1, and the partition plate five 25. The separation chamber is composed of the partition plate five 25 and the equipment main body 1. The partition plate one 21 is fixedly connected in the dilution chamber, the partition plate three 23 is fixedly connected in the mixing chamber, and a filter screen 26 is fixedly connected between the partition plate five 25 and the equipment main body 1.

[0046] In actual application of this embodiment, the waste phosphoric acid stock solution first flows into the dilution chamber enclosed by the partition 2 22 and the equipment body 1. In the dilution chamber, the partition 1 21 guides and assists the mixing, so that the inflowing stock solution can contact the diluent more evenly, complete the dilution operation, and reach the target concentration range of 20%-30%. The diluted stock solution then enters the mixing chamber composed of the partition 2 22, the equipment body 1 and the partition 4 24. In the mixing chamber, the partition 3 23 further guides and assists the mixing, so that the stock solution and the added lime milk are fully mixed, the pH value is accurately adjusted, and the subsequent addition of coagulant and flocculant is prepared. The coagulant creates a suitable chemical environment to promote the formation of flocs from impurities and oil in the raw liquid. The raw liquid with flocs then flows into the flotation chamber composed of the partition four 24, the equipment body 1 and the partition five 25. At the same time, the raw liquid in the flotation chamber is filtered by the filter screen 26 fixedly connected between the partition five 25 and the equipment body 1. The filtered raw liquid enters the separation chamber surrounded by the partition five 25 and the equipment body 1. The filter screen 26 can intercept larger particles of flocs to prevent them from entering the separation chamber and affecting the subsequent dissolved air and flotation links. The raw liquid in the separation chamber then enters the dissolved air tank 31 through the connecting mechanism 33 for pressurized dissolved air treatment.

[0047] like Figure 3 and Figure 5 As shown, the scraper assembly 4 includes a scraper 41 and a motor 44. The top of the equipment body 1 is rotatably connected to two transmission rollers 43. Transmission is formed between the two transmission rollers 43 and the scraper 41. The outer side of the scraper 41 is evenly and fixedly connected with a transmission belt 42. One of the transmission rollers 43 passes through the equipment body 1 and is fixedly connected to the output shaft of the motor 44.

[0048] When the present embodiment is actually applied, the motor 44 starts to operate, and its output shaft drives a transmission roller 43 fixedly connected thereto to rotate synchronously. Since the two transmission rollers 43 and the scraper 41 form a transmission connection through the transmission belt 42, when one transmission roller 43 rotates, the transmission belt 42 moves accordingly, thereby driving the other transmission roller 43 and the scraper 41 to move on the top of the equipment body 1. After the flotation process is completed in the flotation chamber, a large amount of flocs adsorbed with oil and impurities float to the liquid surface to form a foam layer. As the scraper 41 moves, it can scrape off the foam on the liquid surface of the flotation chamber. The scraped foam slides down the scraper 41 to a designated position, which is convenient for centralized cleaning, ensuring the cleanliness of the liquid surface in the flotation chamber, maintaining the efficient progress of the flotation process, ensuring that the oil and slag removal equipment stably and continuously treats the chemical polishing waste phosphoric acid stock solution, and improving the overall treatment effect and work efficiency. In addition, the scraper 41 can also realize the cleaning of the flocs on the top of the filter screen 26.

[0049] like Figure 6 As shown, the connecting mechanism 33 further includes a piston 332 symmetrically slidably connected to the inside of the gas dissolving tank 31 , and inert gas is stored between the piston 332 and the gas dissolving tank 31 .

[0050] In practical application of this embodiment, as the phosphoric acid stock solution enters, the pressure in the dissolved air tank 31 gradually increases. At this time, the piston 332 symmetrically and slidably connected inside the dissolved air tank 31 starts to play a role. Since there is inert gas stored between the piston 332 and the dissolved air tank 31, when the pressure in the dissolved air tank 31 increases, the piston 332 is affected by the pressure of the stock solution and will slide in the direction of compressing the inert gas. The inert gas is compressed, which plays a role in buffering and stabilizing the pressure change in the dissolved air tank 31 and avoids a sharp instantaneous increase in pressure.

[0051] When the pressure in the dissolved air tank 31 reaches the specified value, the opening and closing mechanism 35 acts. The phosphoric acid stock solution after dissolving air in the dissolved air tank 31 enters the air flotation chamber through the air flotation pipe 36. As the stock solution flows out, the pressure in the dissolved air tank 31 decreases. At this time, the compressed inert gas starts to expand, pushing the piston 332 to slide in the reverse direction, supplementing the pressure reduced due to the outflow of the stock solution, maintaining the relative stability of the pressure in the dissolved air tank 31, ensuring the stability and continuity of the dissolved air effect, enabling uniform and stable bubbles to be continuously generated during the air flotation process, effectively combining with the flocs, and improving the efficiency and quality of oil and slag removal.

[0052] As Figure 5 shown, sealing rings 338 are symmetrically and fixedly connected inside the tee pipe 334. The movable seat 337 is rotatably connected between the two sealing rings 338. A water pump 34 is fixedly installed on the outer side of the connecting pipe 331.

[0053] In practical application of this embodiment, the phosphoric acid stock solution in the separation chamber flows towards the tee pipe 334 through the connecting pipe 331 under the suction force generated by the water pump 34. The sealing rings 338 symmetrically and fixedly connected inside the tee pipe 334 closely fit the movable seat 337, providing a stable and sealed environment for its rotation and preventing the leakage of the stock solution.

[0054] As Figure 9 shown, a sealing seat 339 is fixedly connected to the top of the dissolved air tank 31. The connecting rod 336 is rotatably connected to the sealing seat 339.

[0055] In practical application of this embodiment, the rotational connection between the connecting rod 336 and the sealing seat 339 provides a stable and sealed rotational support point for the connecting rod 336, ensuring that the connecting rod 336 can smoothly drive the movable seat 337 to rotate in the tee pipe 334, enabling the L-shaped hole inside the movable seat 337 to accurately adjust the communication state between the dissolved air tank 31 and the separation chamber. While allowing the phosphoric acid stock solution to smoothly enter the dissolved air tank 31, the sealing seat 339 also plays a good sealing role, preventing the high-pressure gas and liquid in the dissolved air tank 31 from leaking from the connection between the connecting rod 336 and the top of the dissolved air tank 31.

[0056] As Figure 6 and Figure 7As shown, a pressurizing port 373 is opened inside the pressurizing seat 371 , and a three-way groove 372 is fixedly connected to the top of the pressurizing seat 371 .

[0057] In actual application of this embodiment, the three-way groove 372 fixedly connected to the top of the pressurizing seat 371 acts as a gas input channel. The external gas source can transport gas to the pressurizing seat 371 through the three-way groove 372, and through the connection between the connecting frame 358 and the sealing plate 352, it can be synchronized with the conversion of the dissolved gas space to ensure that the dissolved gas space can still be stably pressurized after the conversion.

[0058] like Figure 8 As shown, a slider 353 is fixedly connected to the bottom of the sealing plate 352, a slider 354 is slidably connected to the inside of the mounting seat 351, a clamping block 356 is slidably connected to the inner side of the slider 354, a spring 1 355 is symmetrically fixedly connected between the slider 354 and the clamping block 356, a spring 2 359 is symmetrically fixedly connected between the slider 354 and the inner wall of the mounting seat 351, and a guide rod 357 is symmetrically fixedly connected to the inside of the mounting seat 351, and the guide rod 357 passes through the clamping block 356 and the slider 354.

[0059] In actual application of this embodiment, the pressure in the dissolved air tank 31 is transmitted to the flotation tube 36 through the connecting mechanism 33. When the pressure in one of the flotation tubes 36 is too high, the sealing plate 352 is pushed down, and the sealing plate 352 squeezes the block 356 in the slide seat 354. The block 356 slides down under the guidance of the guide rod 357, driving the slider 353 to move, so that the sealing plate 352 is stored in the mounting seat 351, and the flotation tube 36 is opened. At the same time, this sealing plate 352 is linked with the pressurizing seat 371 through the connecting frame 358, driving the sealing plate 352 in the mounting seat 351 at the top of the other flotation tube 36 to seal the flotation tube 36, thereby realizing the alternating opening and closing of the two flotation tubes 36.
