Description

Technical Field

[0001] The utility model relates to the field of corn wastewater treatment, and in particular to water treatment and recycling equipment. Background Art

[0002] Corn steepwater refers to process wastewater generated during corn processing. It contains approximately 10% dry matter, including organic components such as protein, sugars, lactic acid, and amino acids. If discharged directly without treatment, this wastewater can pollute the environment. However, with proper treatment and recycling, the organic components can be transformed into valuable resources. For example, by extracting components such as soluble protein and lactic acid, they can be used as a protein raw material in feed mills and as a fermentation medium in pharmaceutical factories, truly turning waste into treasure.

[0003] The current existing method for treating corn soaking water generally involves adding a large amount of chemicals into a sedimentation tank at one time and then waiting for it to naturally settle. The distribution of chemicals in this treatment method is relatively uneven, resulting in different treatment rates for corn soaking water in different parts. As a result, the above treatment method has a relatively low efficiency in recycling corn soaking water. At the same time, when the corn soaking water is treated and recycled, some toxic and harmful gases, such as hydrogen sulfide and ammonia, are released, causing damage to the working environment. Therefore, how to invent a water treatment and recycling equipment to improve these problems has become a problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0025] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example

[0027] Reference Figure 1-5 A water treatment and recycling equipment includes a sedimentation tank 1 and supporting legs 2 fixedly installed around the lower end surface of the sedimentation tank 1. A transmission column 3 is rotatably installed in the middle of the inner cavity of the sedimentation tank 1, and auger blades 4 are fixedly installed on the left and right sides of the side walls of the transmission column 3. A pressure accumulator tank 5 is fixedly installed on the rear end surface of the sedimentation tank 1. The inner cavity of the pressure accumulator tank 5 is provided with a liquid adding mechanism 6. A filling frame 7 is fixedly installed in the middle of the upper end surface of the sedimentation tank 1, and purification mechanisms 8 are provided on the left and right sides of the upper end surface of the sedimentation tank 1.

[0028] Furthermore, a mixing hole is provided on the side wall of the auger blade 4, and the auger blades 4 on the left and right sides are symmetrically arranged with the axis center of the transmission column 3. A support plate 31 is fixedly installed on the right side wall of the sedimentation box 1, and a worm 32 is rotatably installed in the inner cavity of the support plate 31. A worm gear 33 is meshed and connected below the worm 32, and the worm gear 33 is fixedly connected to the transmission column 3. A servo motor 34 is fixedly installed on the right side wall of the sedimentation box 1 through a frame, and the servo motor 34 is fixedly connected to the output shaft end of the transmission column 3. A sewage pipe 11 is provided at the lower part of the side wall of the sedimentation box 1.

[0029] It should be noted that: when the servo motor 34 is started, the worm 32 rotates, and the worm gear 33 will drive the transmission column 3 to rotate. At this time, the auger blades 4 on the left and right sides will rotate inside the sedimentation box 1. By symmetrically arranging the auger blades 4 on the left and right sides with respect to the axis center of the transmission column 3, the wastewater in the sedimentation box 1 can be mixed in a counter-attack manner, thereby effectively improving the stirring effect of the entire equipment.

[0030] Furthermore, the liquid adding mechanism 6 includes a piston plate 61 slidably mounted on the inner cavity of the pressure accumulator tank 5, and an extension rod 62 fixedly mounted on the inner cavity of the piston plate 61, a return spring 63 is wound around the side wall of the extension rod 62, and a cam 64 is fixedly mounted on the middle part of the side wall of the transmission column 3, both ends of the return spring 63 are fixedly connected to the side wall of the piston plate 61 and the inner wall of the pressure accumulator tank 5 respectively, the extension rod 62 is connected with the pressure accumulator tank 5, the extension rod 62 is fitted with the side wall of the cam 64, and a liquid storage box 65 is fixedly mounted on the rear side wall of the sedimentation tank 1 at the upper part of the pressure accumulator tank 5. The liquid storage box 65 is connected to the pressure accumulator tank 5 through a liquid inlet pipe 66. The inner cavity of the liquid inlet pipe 66 is provided with a one-way water valve with an outlet to the inner cavity of the pressure accumulator tank 5. The extension rod 62 is connected to the pressure accumulator tank 5, and a one-way water valve with an outlet to the inner cavity of the extension rod 62 is provided at the connection point between the extension rod 62 and the pressure accumulator tank 5. A liquid outlet groove 621 is provided on the side wall of the extension rod 62.

[0031] It should be noted that: when the transmission column 3 rotates, the cam 64 also rotates accordingly, and when the extension rod 62 is continuously squeezed, the piston plate 61 moves back and forth in the pressure accumulator tank 5. When the piston plate 61 moves to the rear side of the pressure accumulator tank 5, the chemical agent in the cavity on the rear side of the pressure accumulator tank 5 can be sprayed out from the liquid outlet groove 621 through the extension rod 62. When the piston plate 61 moves to the front side of the pressure accumulator tank 5, the chemical agent in the liquid storage box 65 can enter the pressure accumulator tank 5 through the liquid inlet pipe 66, thereby replenishing the chemical agent capacity.

[0032] Furthermore, the purification mechanism 8 includes a purification box 81 fixedly mounted on the left and right sides of the upper end surface of the sedimentation box 1, and an activated carbon plate 82 fixedly mounted on the inner side wall of the purification box 81. The side wall of the activated carbon plate 82 is paved with a zeolite and alumina composition. An air outlet pipe 83 is provided at the lower part of the side wall of the purification box 81, and an air inlet pipe 84 connected to the sedimentation box 1 is fixedly mounted on the purification box 81.

[0033] It should be noted that when corn wastewater reacts with chemical agents, a certain amount of toxic and harmful gases (such as hydrogen sulfide, ammonia, etc.) will be released. At this time, the exhaust gas will be immersed in the purification box 81 through the air inlet pipe 84. Under the action of the activated carbon plate 82 and the zeolite and alumina composition laid on its surface, the exhaust gas can be effectively filtered, and finally fresh air is discharged from the exhaust pipe 83, ensuring a healthy and good working environment for the staff.

[0034] The working principle of this water treatment and recycling equipment:

[0035] After the user adds a sufficient amount of corn wastewater into the sedimentation tank 1 from the filling frame 7, and then adds an appropriate amount of chemical agent (the chemical agent is a mixture of sodium hydroxide, lime, or sulfuric acid and water) into the pressure accumulator tank 5 and the water storage tank 65, the worm 32 rotates when the servo motor 34 is started, and the worm gear 33 drives the transmission column 3 to rotate the cam 64. When the extension rod 62 is continuously squeezed, the piston plate 61 moves back and forth in the pressure accumulator tank 5. When the piston plate 61 moves to the rear side of the pressure accumulator tank 5, the chemical agent in the cavity on the rear side of the pressure accumulator tank 5 can be sprayed out from the liquid outlet 621 through the extension rod 62. At this time, accompanied by the continuously rotating auger blades 4, the chemical liquid can be evenly and fully mixed in the corn wastewater, effectively improving the efficiency and quality of the subsequent corn wastewater sedimentation;

[0036] When corn wastewater reacts with chemicals, a certain amount of toxic and harmful gases (such as hydrogen sulfide, ammonia, etc.) will be released. At this time, the waste gas will be immersed in the purification box 81 through the air inlet pipe 84. The activated carbon plate 82 and the zeolite and alumina composition laid on its surface can effectively filter the waste gas, and finally fresh air is discharged from the air outlet pipe 83, ensuring a healthy and good working environment for the staff.
