Description

Technical Field

[0001] This invention relates to the technical field of wastewater treatment devices, and more particularly to a wastewater purification and treatment device for phosphate production. Background Technology

[0002] Phosphate is an important raw material in industrial production and is widely used in fertilizers, food additives, detergents and other fields. However, the production of phosphate generates a large amount of high-concentration wastewater, which contains phosphate, heavy metal ions (such as cadmium, lead and zinc), suspended solids and acidic or alkaline components. Direct discharge of this wastewater will lead to eutrophication of water bodies, soil pollution and ecological damage, as well as a serious waste of phosphorus resources.

[0003] In existing technologies, wastewater generated during production needs to be purified and recycled, which can both recover useful resources from the wastewater and prevent environmental pollution.

[0004] For example, Chinese patent application number CN202211356370.X discloses an evaporation and concentration tank for treating high-salt wastewater. It mentions that: a motor drives a lead screw to rotate, causing a lifting plate to move the wastewater upwards. The wastewater level is above the inlet pipe, facilitating the injection of an appropriate amount of wastewater into the annular retaining tube. The evaporator delivers high-temperature steam to the air inlet pipe, placing the annular retaining tube in a high-temperature environment, which facilitates the evaporation of water in the wastewater. The motor drives a shaft to rotate, causing a support to rotate the annular retaining tube inside the annular support shell. The wastewater flows at different positions inside the annular retaining tube, promoting the efficiency of wastewater evaporation.

[0005] However, in the above technical solution, simply shaking the wastewater in the interception pipe results in low wastewater flow efficiency and low evaporation efficiency. Furthermore, as the wastewater evaporates, solid salt crystals easily accumulate on the inner wall of the pipe, which can easily cause blockage in the interception pipe, thus affecting the evaporation and concentration effect. Summary of the Invention

[0006] In view of the above problems, the present invention provides a wastewater purification and treatment device for phosphate production, the purpose of which is to ensure evaporation and recovery efficiency.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0012] Furthermore, the device also includes a bullseye wheel, which passes through the guide member and is fixedly mounted on the second mounting rod, with one end of the bullseye wheel rolling in contact with the first intercepting tube.

[0013] Furthermore, the actuating component includes a spherical outer shell and a spherical inner core, the spherical inner core and the guiding component being attracted by magnetism.

[0022] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0023] Reference Figure 1 and Figure 2As shown in the figure, this application discloses a wastewater purification and treatment device for phosphate production, comprising: a main body 1, fixedly installed on the ground and hollow inside; a first intercepting pipe 11 and a second intercepting pipe 12 connected to each other, staggeredly installed inside the main body 1, forming a circulation channel inside the first intercepting pipe 11 and the second intercepting pipe 12; a feeding pipe 31 connected to the first intercepting pipe 11 and the second intercepting pipe 12 for inputting wastewater; a discharging pipe 32 connected to the first intercepting pipe 11 and the second intercepting pipe 12 for outputting concentrated liquid; a magnetically attracted actuating component 4 and a guiding component 5, wherein the actuating component 4 is movably placed inside the first intercepting pipe 11 and the second intercepting pipe 12 for actuating the wastewater; the guiding component 5 is located outside the first intercepting pipe 11 and the second intercepting pipe 12 and can circulate along the distribution path of the first intercepting pipe 11 and the second intercepting pipe 12; a driving component for driving the guiding component 5; and an evaporation component for inputting water vapor into the main body 1.

[0024] Specifically, one end of the feeding pipe 31 is connected to the first intercepting pipe 11, and the other end of the feeding pipe 31 is connected to a water tank for storing wastewater. Wastewater generated from phosphate production can be pumped into the first intercepting pipe 11 through the feeding pipe 31. The wastewater then flows into the first intercepting pipe 11 and the second intercepting pipe 12. The evaporation assembly is then started to supply steam to the main body 1 for heating, evaporating the wastewater in the first intercepting pipe 11 and the second intercepting pipe 12. Simultaneously, the drive assembly is started, which drives the guide component 5 to move. As the guide component 5 circulates along the distribution path of the first intercepting pipe 11 and the second intercepting pipe 12, the guide component 5 can drive the agitator component to circulate within the first intercepting pipe 11 and the second intercepting pipe 12. The agitator component 4 can move the wastewater within the first intercepting pipe 11 and the second intercepting pipe 12 during the evaporation process, improving the flow effect of the wastewater in the first intercepting pipe 11 and the second intercepting pipe 12, increasing the evaporation efficiency, and the concentrated liquid after evaporation flows out from the discharge pipe 32.

[0025] In some embodiments, the wastewater fills one-quarter of the height of the first intercepting pipe 11 and the second intercepting pipe 12. The guiding component 5 drives the actuating component 4 to move, which can promote the circulation of wastewater in the first intercepting pipe 11 and the second throttling pipe, thereby further improving the flow effect of wastewater in the first throttling pipe and the second intercepting pipe 12 and improving the evaporation efficiency.

[0026] It is worth mentioning that a pipe is installed inside the main body 1, and steam is supplied by a boiler. After the steam enters the main body 1, it is output upward through nozzles to complete the heating and evaporation of water in the wastewater. Understandably, a vent is provided on the upper side of the main body 1, and a vent pipe is provided on the upper side of the first intercepting pipe 11. One end of the vent pipe is connected to the first intercepting pipe 11, and the other end extends vertically upward through the main body 1 to connect with the atmosphere. It is worth mentioning that the vent pipe can also be connected horizontally to the second intercepting pipe 12.

[0027] In this embodiment, one end of the discharge pipe 32 is connected to the first intercepting pipe 11, and the other end of the discharge pipe 32 extends vertically downward out of the main body 1; the discharge pipe 32 can also be connected horizontally to the second intercepting pipe 12 to ensure that the concentrate can be fully discharged, and a valve can be installed on the discharge pipe 32 to control its opening and closing.

[0028] In this invention, the first intercepting pipe 11 and the second intercepting pipe 12 can temporarily store wastewater, effectively ensuring the residence time of wastewater within the main body 1 and guaranteeing evaporation efficiency. Furthermore, a pulsating component and a guiding component 5 are provided. The guiding component 5 can drive the agitating component 4 to move, thereby agitating the wastewater flow within the first and second intercepting pipes 11 and 12, improving the flow efficiency of wastewater within these pipes. This further facilitates the formation of a water film on the inner walls of the first and second intercepting pipes 11 and 12, enhancing the efficiency of wastewater flow. The evaporation efficiency of water is improved; in addition, the first intercepting pipe 11 and the second intercepting pipe 12 are connected, and the wastewater in the first intercepting pipe 11 and the second intercepting pipe 12 can mix and circulate, further improving the evaporation efficiency; during the movement of the moving part 4, the moving part can contact the inner wall surface of the first intercepting pipe 11 and the second intercepting pipe 12 to clean the inner wall surface of the first intercepting pipe 11 and the second intercepting pipe 12, ensuring the cleanliness of the inner wall surface and preventing the accumulation of solid salt crystals on the inner wall surface. The salt crystals are discharged outward from the discharge pipe 32 along with the concentrated liquid, which can effectively ensure the efficiency of evaporation and concentration.

[0029] Specifically, the first intercepting pipe 11 includes: two horizontally installed first pipe fittings 111; two arc-shaped pipe fittings that connect the two ends of the two first pipe fittings 111 respectively to form a loop; the second intercepting pipe 12 is annular, with the two first pipe fittings 111 sleeved inside the second intercepting pipe 12, and the inner side of the second intercepting pipe 12 fixedly installed on the two first pipe fittings 111.

[0030] Preferably, the central axis of the second intercepting tube 12 is perpendicular to the axis of the first tube 111, and the two first tubes 111 are symmetrically located at both ends of one of the diameters of the second intercepting tube 12.

[0031] Preferably, the first intercepting pipe 11 and the second intercepting pipe 12 are installed in a cross shape to form a circulation channel for wastewater flow.

[0032] In this embodiment, two second intercepting pipes 12 are provided and installed in parallel. A first intercepting pipe 11 is inserted inside the second intercepting pipe 12. A through hole is opened on the outer side of the first intercepting pipe 11 and the inner side of the second intercepting pipe 12. The through hole is welded around to prevent leakage. It is worth mentioning that the first intercepting pipe 11 and the second intercepting pipe 12 can be fixedly installed by welding. The first intercepting pipe 11 and the second intercepting pipe 12 are made of antimagnetic materials and are not limited to ceramic and aluminum.

[0033] Continue to refer to Figure 1 As shown, in this embodiment, the drive assembly includes: a first mounting shaft 61, rotatably mounted inside the main body 1, passing between two first pipe fittings 111; a first mounting rod 62, fixedly mounted on the first mounting shaft 61; a second mounting rod 63, one end of which is slidably mounted inside the first mounting rod 62, and the other end abutting against the first intercepting tube 11, with a guide member 5 located at the end of the second mounting rod 63 away from the first mounting shaft 61; an elastic member 64 for supporting the first mounting rod 62; a turntable 65, coaxial with the second intercepting tube 12, rotatably mounted on the main body 1; a third mounting rod 66, one end of which is fixedly mounted on the turntable 65, and the other end extending toward the second intercepting tube 12, with a guide member 5 located at the end of the third mounting rod 66 away from the turntable 65; a first drive motor for driving the first mounting shaft 61 to rotate; and a second drive motor 67 for driving the turntable 65 to rotate.

[0034] In this embodiment, the first drive motor (not shown in the figure) is installed outside the main body 1. The output shaft of the first drive motor is connected to the first mounting shaft 61 through a coupling. The rotation of the output shaft of the first drive motor can drive the second mounting rod 63 to rotate, thereby driving the first mounting rod 62 to rotate. The end of the first mounting rod 62 away from the first mounting shaft 61 can drive the guide component 5 to move along the inner contour of the first intercepting tube 11, thereby moving the guide actuating component 4 inside the first intercepting tube 11.

[0035] In this embodiment, the third mounting rod 66 is installed parallel to the central axis of the second intercepting tube 12, and the turntable 65 is rotatably and sealedly mounted on the main body 1. An internal gear 71 is provided on one side of the turntable 65, and a drive gear 72 is installed on the output shaft of the second drive motor 67. The drive gear 72 meshes with the internal gear 71. By rotating the output shaft of the second drive motor 67, the turntable 65 can be driven to rotate. During the rotation of the turntable 65, the third mounting rod 66 can be driven to move along the outer contour of the second intercepting tube 12, thereby driving the actuating component 4 to move inside the second intercepting tube 12.

[0036] Reference Figure 4As shown, in this embodiment, the device also includes a bullseye wheel 68, which passes through the guide component 5 and is fixedly installed on the second mounting rod 63. One end of the bullseye wheel 68 rolls in contact with the first intercepting tube 11. By setting the bullseye wheel 68, wear can be effectively prevented and service life can be guaranteed.

[0037] Continue to refer to Figure 4 As shown, the actuating component 4 includes a spherical outer shell 41 and a spherical inner core 42. The spherical inner core 42 and the guide component 5 are attracted by magnetism. In this embodiment, the spherical outer shell 41 is hollow inside, and the volume of the spherical inner core 42 is smaller than that inside the spherical outer shell 41. Under the action of the guide component 5, the spherical inner core 42 can be eccentrically pressed into the spherical outer shell 41.

[0038] Preferably, the actuating component 4 further includes: an isolation layer 44 and a plurality of balls 45, the isolation layer 44 being located between the spherical outer shell 41 and the spherical inner core 42, the plurality of balls 45 being rotatably embedded in the isolation layer 44, and the balls 45 being rotatably supporting the spherical inner core 42 and the spherical outer shell 41.

[0039] By setting ball bearings 45, the two sides of the ball bearings 45 can roll to support the spherical outer shell 41 and the spherical inner core 42 respectively. Under the action of the guide component 5, the guide component 5 attracts the spherical inner core 42, and the spherical inner core 42 presses the spherical outer shell 41 into the first intercepting tube 11 / second intercepting tube 12. During the movement of the guide component 5, the guide component 5 can drive the spherical inner core 42 to move. During the movement, it can synchronously drive the spherical outer shell 41 to roll, and drive the spherical outer shell 41 to roll and contact the inner wall surface of the pipe, further improving the cleaning efficiency of the inner wall surface.

[0040] Reference Figure 3 As shown, the actuating component 4 also includes several annular edges 43, which are alternately installed on the spherical shell 41. By setting the annular edges 43, the edges 43 can scrape the inner wall surface of the pipe during the rolling of the spherical shell 41, which can further improve the cleaning efficiency of the inner wall surface.

[0041] In this embodiment, the ball bearing 45, the insulating layer 44, and the spherical outer shell 41 are all made of antimagnetic materials, and are not limited to ceramic and aluminum.

[0042] It is worth mentioning that both the guide component 5 and the spherical inner core 42 can be made of commercially available permanent magnets that can work in high-temperature environments, such as samarium iron nitrogen permanent magnets, aluminum nickel cobalt permanent magnets and samarium cobalt permanent magnets; or the guide component 5 can be made of a permanent magnet, while the spherical inner core 42 can be made of a metal that can be attracted by magnetism (such as iron / nickel / cobalt).
