Description

Technical Field

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

[0002] During the preparation of ammonium chloride, a large amount of wastewater is generated. If this wastewater is directly discharged 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 various metal ions, suspended solids, organic substances, 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 damage the ecological balance. The treatment of ammonium chloride preparation wastewater usually adopts a multi-stage treatment process to gradually remove different types of pollutants and make the wastewater meet the discharge standards.

[0003] Traditional purification treatment devices for ammonium chloride preparation wastewater usually consist of multiple independent units, and each unit performs different treatment functions respectively. This traditional mode has many drawbacks. The combination of multiple independent units results in a large overall equipment volume, which requires a large amount of site space, increases the operation cost and management difficulty. When the wastewater is transferred between different units, problems such as extended treatment time and insufficient reaction are likely to occur.

[0004] Multiple independent units need to purchase more equipment, increasing the initial investment cost. Moreover, the complex connecting pipes and lines between the equipment also increase the probability of failures and the difficulty of maintenance. Summary of the Invention

The water distribution mechanism is used to evenly distribute the preliminarily purified water to the adsorption layer.

Liquid storage grooves are formed on the upper surface of the spiral blades. Baffle plates are fixedly installed inside the liquid storage grooves. The baffle plates increase the contact time between the wastewater and the flocculant, making their mixing in the liquid storage grooves more sufficient.

[0010] Preferably, the conveying member includes a rotating seat fixedly installed at the bottom of the first transmission shaft. An installation rotating ring is fixedly installed on the outer surface of the rotating seat, and a spiral conveying blade is fixedly installed inside the installation rotating ring.

[0014] Preferably, a liquid distribution plate is fixedly installed at the top of the water outlet pipe. Leakage holes are formed on the surface of the liquid distribution plate.

The rotating conical seat is arranged inside the diversion ring, and a spiral groove is formed on the outer surface of the rotating conical seat.

[0015] The present invention provides a purification treatment device for wastewater in ammonium chloride preparation. It has the following beneficial effects: First, in this purification treatment device for wastewater in ammonium chloride preparation, through the setting of the stirring mechanism, the first motor drives the first transmission shaft to rotate, and the spiral blades fixed on the outer surface of the first transmission shaft rotate accordingly, pushing the wastewater to flow inside the machine shell. The wastewater and the flocculant enter the liquid storage tank on the upper surface of the spiral blade during the flowing process. The baffle in the liquid storage tank hinders the fluid from passing through quickly, enabling the wastewater and the flocculant to have more time to contact and mix with each other. The preliminarily mixed fluid is transported to the conveying member at the bottom as the first transmission shaft rotates. The rotating seat rotates with the first transmission shaft, driving the installation rotating ring and the internal spiral conveying blade to rotate, and transporting the preliminarily mixed fluid to the lower separation cylinder. At the same time, the second transmission shaft connects the conveying member and the stirring rod, transmitting power to the stirring rod. The stirring rod rotates inside the separation cylinder, further stirring the wastewater and the flocculant in the cylinder, greatly improving the flocculation effect, providing better conditions for subsequent separation and purification steps, reducing the problem of poor treatment effect caused by insufficient mixing, and improving the efficiency and quality of the overall wastewater treatment.

[0016] II. The purification treatment device for the ammonium chloride preparation wastewater, through the setting of the separation mechanism, the motor II drives the transmission shaft III to drive the separation cylinder at the top to rotate. When the separation cylinder rotates counterclockwise, the current-limiting grooves distributed between the sieve holes hinder the outflow of the liquid, restricting the liquid from flowing out of the sieve holes, so that the wastewater and the flocculant continuously react and mix fully in the separation cylinder; when the separation cylinder rotates clockwise, the water preliminarily purified after sufficient flocculation reaction flows into the machine shell from the sieve holes evenly distributed on the surface of the separation cylinder, while the floccules and large-particle impurities in the wastewater remain in the separation cylinder due to the action of gravity and the blockage of the sieve holes. Through the rotation in different directions and the design of the current-limiting grooves and sieve holes, the separation cylinder realizes the integrated operation of reaction and separation. When rotating counterclockwise, the reaction time is prolonged to ensure the full progress of the flocculation reaction; when rotating clockwise, solid-liquid separation is completed, improving the treatment efficiency.

[0017] III. The purification treatment device for the ammonium chloride preparation wastewater, through the setting of the water distribution mechanism, the water preliminarily purified flowing out of the separation cylinder directly falls into the liquid collection box directly below. After the liquid collection box collects the water flow, the water flow passes through the liquid distribution plate at the top of the water outlet pipe, and the liquid leakage holes on the surface of the liquid distribution plate make the water in the liquid collection box flow down evenly. The flowing water passes through the cooperation of the rod seat and the rotating cone seat, and the spiral groove on the outer surface of the rotating cone seat further disperses the water flow evenly. Finally, through the guidance of the diversion ring, the water is evenly distributed to the adsorption layer below. The water distribution mechanism ensures that the water preliminarily purified can be evenly distributed to the adsorption layer, and the uniform water distribution enables each part of the adsorption layer to give full play to its role, improving the adsorption efficiency of the adsorption layer and prolonging the service life of the adsorption material.

[0018] IV. The purification treatment device for the ammonium chloride preparation wastewater, through the setting that the adsorption layer is activated carbon, the water preliminarily purified evenly distributed by the water distribution mechanism passes through the adsorption layer composed of activated carbon from top to bottom. Activated carbon has a rich pore structure and a large specific surface area. When the water flow passes through, the residual organic matter, residual flocculant, and odor and other impurities in the water are adsorbed on the surface of the activated carbon, further improving the water quality, enabling the purified water to meet more stringent environmental protection standards, and reducing the pollution risk to natural water bodies.

[0019] V. The purification treatment device for the ammonium chloride preparation wastewater, through the setting of the rolling grooves and the balls, when the conveying part rotates with the transmission shaft I, the balls roll between the rolling groove I, the rolling groove III and the rolling groove II, playing a role in supporting and assisting rotation. The cooperation of the rolling grooves and the balls greatly reduces the friction when the conveying part rotates, reduces the wear between the equipment parts, prolongs the service life of the equipment, and reduces the frequency of equipment maintenance and replacement.

[0025] For the third embodiment, on the basis of the first and second embodiments, please refer to Figures 1 to 12 As shown, the water distribution mechanism 7 is fixedly installed on the inner wall of the housing 1. The water distribution mechanism 7 is arranged on the outer side of the separation mechanism 6. An adsorption layer 8 is arranged directly below the water distribution mechanism 7. The adsorption layer 8 is fixedly installed on the inner wall of the housing 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. The water distribution mechanism 7 includes a liquid collecting box 71. The liquid collecting box 71 is arranged directly below the separation cylinder 63. The liquid collecting box 71 is fixedly installed on the inner wall of the housing 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. A diversion ring 73 is fixedly connected to the bottom of the water outlet pipe 72.

[0026] A liquid distribution plate 74 is fixedly installed at the top of the water outlet pipe 72. Leakage holes 75 are formed on the surface of the liquid distribution plate 74. A rod seat 76 is fixedly connected to the middle of the bottom of the liquid distribution plate 74. A rotating cone seat 77 is rotatably installed on the outer surface of the rod seat 76.

When the water flow passes through the spiral groove 78, the rotating cone seat 77 rotates on the surface of the rod seat 76, further evenly dispersing the water flow. Then, through the guidance of the diversion ring 73, the water is evenly distributed to the adsorption layer 8 below.

[0027] During use, the operator pours the wastewater and the flocculant into the casing 1 through the feed hopper 3, starts the first motor 51 and the second motor 61. The first motor 51 drives the first transmission shaft 52 to rotate, and the spiral blade 531 fixed on the outer surface of the first transmission shaft 52 rotates accordingly, pushing the wastewater to flow in the casing 1. The wastewater and the 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 fluid flow, prolongs the contact time between the wastewater and the flocculant, and enables them to be fully mixed; The preliminarily mixed fluid is conveyed to the bottom conveying member 54 as the first transmission shaft 52 rotates. The rotating seat 541 rotates with the first transmission shaft 52, driving the installation rotating ring 542 and the internal spiral conveying sheet 543 to rotate, and transporting the mixed liquid to the lower separation cylinder 63. At the same time, the second transmission shaft 55 connects the conveying member 54 and the stirring rod 56, transmitting power to the stirring rod 56.

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 the flocculant to react more fully in the separation cylinder 63 to form flocs. When the separation cylinder 63 rotates clockwise, the preliminarily purified water after flocculation flows into the casing 1 from the sieve holes 65 evenly distributed on the surface of the separation cylinder 63, while the flocs and large particle impurities in the wastewater remain in the separation cylinder 63; 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 leads out the water through the water outlet pipes 72 evenly distributed at the bottom. The liquid leakage holes 75 on the surface of the liquid distribution plate 74 make the water in the liquid collection box 71 flow down evenly. Through the cooperation of the rod seat 76 and the rotating cone seat 77, the spiral groove 78 on the outer surface of the rotating cone seat 77 further evenly disperses the water flow, and then through the guiding of the guiding ring 73, the water is evenly distributed to the lower adsorption layer 8 below. The adsorption layer 8 is composed of activated carbon, and using the adsorption performance of the activated carbon, the residual impurities in the water are further removed; The water purified by the adsorption layer 8 continues to flow downward under the action of gravity. The guiding plate 9 at the bottom of the inner cavity of the casing 1 guides the purified wastewater to the water outlet 12, and finally discharges 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 and opened for operation.
