Description

Technical Field

[0001] The invention relates to the technical field of wastewater purification and treatment, in particular to a purification and treatment device for ammonium chloride preparation wastewater. Background Art

[0002] During the preparation of ammonium chloride, a large amount of wastewater is generated. If this wastewater is discharged directly without effective treatment, it will cause serious pollution to the environment. In addition to containing a large amount of ammonium chloride, the wastewater may also contain a variety of metal ions, suspended matter, organic matter and other impurities. If these pollutants enter natural water bodies, they will cause eutrophication of the water bodies, affect the living environment of aquatic organisms, and destroy the ecological balance. The treatment of ammonium chloride preparation wastewater usually adopts a multi-stage treatment process, which aims to gradually remove different types of pollutants so that the wastewater meets the discharge standards.

[0003] Traditional ammonium chloride production wastewater purification treatment equipment is usually composed of multiple independent units, each of which performs different treatment functions. This traditional model has many disadvantages. The combination of multiple independent units makes the overall equipment bulky and requires a large amount of site space, which increases operating costs and management difficulties. When wastewater is transferred between different units, problems such as extended treatment time and insufficient reaction are prone to occur.

[0004] Multiple independent units require more equipment, increasing initial investment costs. Furthermore, the complex connecting pipes and wiring between devices increases the probability of failure and the difficulty of repair. Summary of the Invention

A liquid storage tank is provided on the upper surface of the spiral blade, and a baffle is fixedly mounted inside the liquid storage tank.

[0020] The present invention provides a purification treatment device for ammonium chloride production wastewater. It has the following beneficial effects:

[0021] 1. This ammonium chloride wastewater purification and treatment device, through the setting of the stirring mechanism, drives the transmission shaft 1 to rotate, and the spiral blades fixed to the outer surface of the transmission shaft 1 rotate accordingly, pushing the wastewater to flow within the casing. During the flow, the wastewater and flocculant enter the liquid storage tank on the upper surface of the spiral blade. The baffle plate in the liquid storage tank prevents the rapid passage of the fluid, allowing the wastewater and flocculant more time to contact and mix with each other. The initially mixed fluid is transported to the conveying member at the bottom as the transmission shaft 1 rotates. The rotating seat rotates with the transmission shaft 1, driving the installation ring and the internal spiral conveying plate to rotate, transporting the initially mixed fluid to the separation drum below. At the same time, the transmission shaft 2 connects the conveying member and the stirring rod, transmitting power to the stirring rod. The stirring rod rotates within the separation drum, further stirring the wastewater and flocculant in the drum, greatly improving the flocculation effect, providing better conditions for subsequent separation and purification steps, reducing the problem of poor treatment effect due to insufficient mixing, and improving the efficiency and quality of the overall wastewater treatment.

[0022] 2. The purification treatment device for ammonium chloride preparation wastewater has a separation mechanism. The second motor drives the third transmission shaft to rotate the separation drum on the top. When the separation drum rotates counterclockwise, the flow-limiting grooves distributed between the sieve holes hinder the outflow of liquid, restricting the outflow of liquid from the sieve holes, so that the wastewater and flocculant continue to react and fully mix in the separation drum. When the separation drum rotates clockwise, the water that has undergone sufficient flocculation reaction and is preliminarily purified flows into the casing from the sieve holes evenly distributed on the surface of the separation drum, while the flocculants and large particles of impurities in the wastewater remain in the separation drum due to gravity and the blocking effect of the sieve holes. The separation drum realizes the integrated operation of reaction and separation through rotation in different directions and the design of the flow-limiting grooves and sieve holes. Counterclockwise rotation prolongs the reaction time to ensure that the flocculation reaction is fully carried out; clockwise rotation completes solid-liquid separation, thereby improving the treatment efficiency.

[0023] Third, the ammonium chloride production wastewater purification device utilizes a water distribution mechanism, allowing the initially purified water flowing from the separation cylinder to fall directly into the liquid collection box directly below. After the liquid collection box collects the water, it flows through the liquid separation plate at the top of the outlet pipe. The leakage holes on the surface of the liquid separation plate allow the water in the liquid collection box to flow evenly. The flowing water then passes through the rod seat and the rotating cone seat, where the spiral grooves on the outer surface of the rotating cone seat further disperse the water evenly. Finally, the water is guided by a guide ring and evenly distributed to the adsorption layer below. The water distribution mechanism ensures that the initially purified water is evenly distributed to the adsorption layer. The even water distribution allows every part of the adsorption layer to fully function, improving the adsorption efficiency of the adsorption layer and extending the service life of the adsorption material.

[0024] 4. The purification treatment device for ammonium chloride preparation wastewater has an activated carbon adsorption layer. The preliminary purified water is evenly distributed by the water distribution mechanism and passes through the adsorption layer composed of activated carbon from top to bottom. The activated carbon has a rich pore structure and a huge specific surface area. When the water flows through, the residual organic matter, residual flocculant, odor and other impurities in the water are adsorbed on the surface of the activated carbon, which further improves the water quality, enables the purified water to meet more stringent environmental protection standards, and reduces the risk of pollution to natural water bodies.

[0025] 5. The purification treatment device for ammonium chloride preparation wastewater, through the arrangement of rolling grooves and balls, when the conveying member rotates with the transmission shaft 1, the balls roll between rolling grooves 1, 3 and 2, playing a role of supporting and assisting the rotation. The combination of rolling grooves and balls greatly reduces the friction force when the conveying member rotates, reduces the wear between equipment components, extends the service life of the equipment, and reduces the frequency of equipment maintenance and replacement.

[0041] The second embodiment, based on the first embodiment, see Figures 1 to 10 As shown, the stirring mechanism 5 is installed in the middle of the casing 1. The stirring mechanism 5 is arranged on the upper part of the casing 1. The stirring mechanism 5 is used to fully mix and react the wastewater and the flocculant;

[0042] The separation mechanism 6 is installed at the bottom of the stirring mechanism 5, and the separation mechanism 6 is used to separate the flocs and the treated water;

[0043] The separation mechanism 6 includes a second motor 61, which is fixedly mounted in the middle of the bottom of the housing 1 via a bracket. The output end of the second motor 61 is fixedly connected to a third transmission shaft 62, which passes through the guide vane 9, the adsorption layer 8, and the water distribution mechanism 7 in sequence. A separation cylinder 63 is fixedly mounted on the top of the transmission shaft 62. A sieve hole 65 is formed on the surface of the separation cylinder 63, and a second rolling groove 64 is formed on the edge of the top of the inner cavity of the separation cylinder 63.

[0044] A bearing 67 is fixedly installed in the middle of the bottom of the inner cavity of the separation cylinder 63. The sieve holes 65 are evenly distributed on the surface of the separation cylinder 63. The inner wall of the separation cylinder 63 is provided with a limiting flow groove 66. The limiting flow groove 66 is arranged between the sieve holes 65. When the separation cylinder 63 rotates counterclockwise, the limiting flow groove 66 restricts the liquid from flowing out of the sieve holes 65, so that the wastewater and the flocculant react more fully in the separation cylinder 63. When the separation cylinder 63 rotates clockwise, the water that has been flocculated and initially purified flows into the housing 1 from the sieve holes 65, and the flocculent and large particles of impurities in the wastewater remain in the separation cylinder 63.

[0045] The stirring mechanism 5 includes a motor 51, which is fixedly mounted in the middle of the top of the casing 1 through a bracket. The output end of the motor 51 is fixedly connected to a transmission shaft 52, and a mixing element 53 is fixedly mounted on the outer surface of the transmission shaft 52. A conveying element 54 is fixedly mounted on the bottom of the transmission shaft 52. A transmission shaft 2 55 is fixedly connected in the middle of the bottom of the conveying element 54. A stirring rod 56 is fixedly mounted on the outer surface of the transmission shaft 55. The stirring rod 56 is disposed inside the separation drum 63, and the bottom end of the stirring rod 56 is rotatably mounted on the inner side of a bearing 67.

[0046] The stirring rod 56 is rotationally symmetrically arranged with respect to the central axis of the second transmission shaft 55. The stirring rod 56 extends obliquely downward from the surface of the second transmission shaft 55. The stirring rod 56 rotates inside the separation drum 63 to further stir and mix the wastewater and flocculant in the drum to make the reaction more complete.

[0047] The mixing element 53 includes a spiral blade 531, which is fixedly mounted on the outer surface of the transmission shaft 1 52. A liquid storage tank 532 is formed on the upper surface of the spiral blade 531, and a baffle 533 is fixedly mounted inside the liquid storage tank 532. The baffle 533 increases the contact time between the wastewater and the flocculant, thereby achieving more complete mixing within the liquid storage tank 532.

[0048] The conveying member 54 includes a rotating base 541, which is fixedly mounted on the bottom of the transmission shaft 1 52. A mounting swivel 542 is fixedly mounted on the outer surface of the rotating base 541, and a spiral conveying piece 543 is fixedly mounted inside the mounting swivel 542. The spiral conveying piece 543 is used to transport the preliminarily mixed fluid to the separation cylinder 63.

[0049] Rolling groove 1 544 is provided on both sides of the outer surface of the mounting swivel 542, and balls 545 are provided inside the rolling groove 1 544. The balls 545 are squeezed and adapted to rolling groove 3 11 and rolling groove 2 64 respectively, which reduces the friction during the rotation of the mechanism, reduces the wear between the equipment components, and extends the service life of the equipment.

[0050] The third embodiment, based on the first and second embodiments, see Figures 1 to 12 As shown, the water distribution mechanism 7 is fixedly mounted on the inner wall of the casing 1. The water distribution mechanism 7 is arranged on the outer side of the separation mechanism 6. An adsorption layer 8 is provided directly below the water distribution mechanism 7. The adsorption layer 8 is fixedly mounted on the inner wall of the casing 1 through a bracket. The water distribution mechanism 7 is used to evenly distribute the preliminarily purified water to the adsorption layer 8. The adsorption layer 8 is specifically activated carbon to further remove impurities in the water.

[0051] The water distribution mechanism 7 includes a liquid collecting box 71, which is arranged directly below the separation cylinder 63. The liquid collecting box 71 is fixedly installed on the inner wall of the casing 1. A water outlet pipe 72 is fixedly installed at the bottom of the liquid collecting box 71. The water outlet pipes 72 are evenly distributed at the bottom of the liquid collecting box 71. The bottom of the water outlet pipe 72 is fixedly connected to a guide ring 73.

[0052] A liquid separation plate 74 is fixedly installed on the top of the water outlet pipe 72, and a leakage hole 75 is provided on the surface of the liquid separation plate 74. A rod seat 76 is fixedly connected to the middle of the bottom of the liquid separation plate 74. A rotating cone seat 77 is rotatably installed on the outer surface of the rod seat 76. The rotating cone seat 77 is arranged inside the guide ring 73. A spiral groove 78 is provided on the outer surface of the rotating cone seat 77. When water flows through the spiral groove 78, the rotating cone seat 77 rotates on the surface of the rod seat 76, further dispersing the water flow evenly, and then guided by the guide ring 73 to evenly distribute the water to the adsorption layer 8 below.

[0053] During use, the operator pours wastewater and flocculant into the housing 1 through the hopper 3, starts the motor 1 51 and the motor 2 61, and the motor 1 51 drives the transmission shaft 1 52 to rotate. The spiral blade 531 fixed to the outer surface of the transmission shaft 1 52 rotates accordingly, pushing the wastewater to flow in the housing 1. The wastewater and flocculant flow into the liquid storage tank 532 on the upper surface of the spiral blade 531. The baffle 533 in the tank hinders the flow of fluid, prolonging the contact time between the wastewater and the flocculant and allowing them to be fully mixed.

[0054] The preliminarily mixed fluid is conveyed to the conveying member 54 at the bottom as the transmission shaft 1 52 rotates. The rotating seat 541 rotates with the transmission shaft 1 52, driving the installation swivel 542 and the internal spiral conveying piece 543 to rotate, and the mixed liquid is transported to the separation cylinder 63 below. At the same time, the transmission shaft 2 55 connects the conveying member 54 and the stirring rod 56, transmitting power to the stirring rod 56. The stirring rod 56 rotates in the separation cylinder 63. Because it is rotationally symmetrical with respect to the central axis of the transmission shaft 2 55 and extends obliquely downward, it can further stir the wastewater and flocculant in the separation cylinder 63, thereby strengthening the reaction between the two.

[0055] At this time, the motor 2 61 drives the separation cylinder 63 to rotate counterclockwise. The flow-limiting grooves 66 distributed between the sieve holes 65 on the inner wall restrict the liquid from flowing out of the sieve holes 65, allowing the wastewater and flocculant to react more fully in the separation cylinder 63 to form flocs. When the separation cylinder 63 rotates clockwise, the initially purified water after flocculation flows into the housing 1 through the sieve holes 65 evenly distributed on the surface of the separation cylinder 63, while the flocs and large particles of impurities in the wastewater remain in the separation cylinder 63.

[0056] The preliminarily purified water flowing out of the separation cylinder 63 falls into the liquid collection box 71 directly below. The liquid collection box 71 collects the water flow and draws it out through the water outlet pipes 72 evenly distributed at the bottom. The leakage holes 75 on the surface of the liquid separation plate 74 allow the water in the liquid collection box 71 to flow down evenly. The rod seat 76 and the rotating cone seat 77 cooperate, and the spiral grooves 78 on the outer surface of the rotating cone seat 77 further disperse the water flow evenly. The water is then guided by the guide ring 73 and evenly distributed to the adsorption layer 8 below. The adsorption layer 8 is composed of activated carbon, and the adsorption properties of the activated carbon are used to further remove residual impurities in the water.

[0057] The water purified by the adsorption layer 8 continues to flow downward under the action of gravity. The guide plate 9 at the bottom of the inner cavity of the casing 1 guides the purified waste water to the water outlet 12, and finally discharged through the water outlet 12, completing the entire purification process. When it is necessary to clean the inside of the device, the sealing door 4 can be rotated to open the operation.

[0058] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device.
