Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, and in particular to a wastewater treatment device for the production of amino acid surfactants. Background Technology

[0002] The production process of amino acid surfactants generates industrial wastewater containing a large amount of organic pollutants, residual raw materials and intermediate products. If this wastewater is discharged directly, it will not only cause serious damage to the aquatic ecological environment, but also easily harm soil quality and human health. Therefore, it must be purified by professional wastewater treatment equipment before it can meet the discharge standards.

[0003] Currently, the common treatment method in the industry is to add specific treatment agents to the wastewater. The agents react with the pollutants in the wastewater to achieve degradation or precipitation, thereby purifying the wastewater. The core of the treatment device is to ensure that the agents and wastewater are fully mixed to ensure the treatment effect and efficiency.

[0004] However, conventional wastewater treatment devices still have shortcomings in practical applications. The stirring equipment in conventional wastewater treatment devices is mostly unidirectional rotational stirring, which can only achieve mixing in a local area and cannot promote the overall convection of wastewater. This affects the uniformity of mixing between the reagent and the wastewater, as well as the reaction effect and efficiency, thus impacting the efficiency and quality of wastewater treatment. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a wastewater treatment device for the production of amino acid surfactants. It aims to improve the problem that the stirring equipment in the existing wastewater treatment devices is mostly unidirectional rotating and stirring, which can only mix locally and cannot promote the overall convection of wastewater, resulting in uneven mixing of reagents and wastewater, affecting the reaction effect and efficiency, and thus reducing the efficiency and quality of wastewater treatment.

[0020] Reference Figure 1 , Figure 2 , Figure 4 The stirring assembly includes a motor 61, which is existing technology and can be implemented by those skilled in the art. As it is existing technology, it will not be described in detail in this case. The motor 61 is set on the upper surface of the treatment tank 2. The output shaft of the motor 61 is fixedly connected to a rotating shaft 62. The motor 61 can drive the rotating shaft 62 to rotate. The outer wall of the rotating shaft 62 is slidably connected to a stirring shaft 63. The rotating shaft 62 and the stirring shaft 63 will rotate synchronously. The outer wall of the stirring shaft 63 is fixedly connected to a stirring blade 64. The stirring blade 64 is used to mix wastewater and treatment agents. Multiple sets of stirring blades 64 are evenly distributed on the outer wall of the stirring shaft 63. The outer wall of the stirring shaft 63 is provided with a guide groove 65. The right end of the inner wall of the treatment tank 2 is fixedly connected to a connecting rod 66. The left surface of the connecting rod 66 is fixedly connected to a guide block 67. The guide block 67 and the guide groove 65 fit together.

[0021] Reference Figure 1 , Figure 2 , Figure 4 The rotating shaft 62 is rotatably connected to the upper surface of the processing tank 2, and the processing tank 2 provides support for the rotating shaft 62. The guide groove 65 is a closed ring at both ends, and the guide groove 65 is inclined with the left side lower and the right side higher. The guide block 67 is set as a hemispherical shape and is slidably connected to the inner wall of the guide groove 65. When the stirring shaft 63 rotates, the guide groove 65 is squeezed by the guide block 67, and the stirring shaft 63 will generate a reciprocating motion in the up and down direction. The outer wall of the rotating shaft 62 is provided with a sliding groove, and the inner surface of the stirring shaft 63 is provided with a sliding key. The sliding key is slidably connected to the inner wall of the sliding groove, which can ensure the stability of the sliding direction of the stirring shaft 63, and the center points of the rotating shaft 62 and the stirring shaft 63 are on the same axis.

[0022] Reference Figures 1-3 The filter assembly includes a support ring 73, which is fixedly connected to the inner wall of the feeding hopper 3. A slot 75 is provided through the inner surface of the support ring 73. A filter plate 71 is placed on the upper surface of the support ring 73. The upper surface of the support ring 73 and the lower surface of the filter plate 71 are in contact. Pull rings 72 are fixedly connected to both ends of the upper surface of the filter plate 71 to facilitate the removal of the filter plate 71. Insert blocks 74 are fixedly connected to the four corners of the lower surface of the filter plate 71. The insert blocks 74 fit into the slots 75.

[0023] Reference Figures 1-3 The insert 74 is inserted into the inner wall of the slot 75. The insert 74 is a flat-topped cone that is wider at the top and narrower at the bottom. The bottom end of the insert 74 is an arc surface, which can provide guidance when the insert 74 and the slot 75 are inserted. The slot 75 is a vertical cylinder. The insert 74 and the slot 75 are in an interference fit, which can ensure the stability of the support ring 73 and the filter plate 71 during installation.

[0024] Working principle: When treating wastewater from the production of amino acid surfactants, the wastewater is first introduced into the feeding hopper 3. The wastewater will first pass through the filter components inside the feeding hopper 3. When the wastewater flows through the filter plate 71, the solid impurities in it are blocked by the filter plate 71. The filtered wastewater enters the treatment tank 2. When it is necessary to clean the impurities on the filter plate 71, the filter plate 71 can be easily removed from the support ring 73 by pulling the pull rings 72 at both ends of the upper surface of the filter plate 71. The operation is convenient. During installation, the filter plate 71 can be inserted into the slots 75 through the inserts 74 at the four corners of the lower surface.

[0025] After the filtered wastewater enters the treatment tank 2, the valve on the feed pipe 4 is opened, and the treatment agent is added into the treatment tank 2 through the feed pipe 4. Then, the motor 61 is started, driving the rotating shaft 62 to rotate. The rotating shaft 62 drives the stirring shaft 63 to rotate synchronously. The stirring blades 64 on the outer wall of the stirring shaft 63 rotate accordingly, initially mixing the wastewater and the treatment agent. At the same time, during the rotation of the stirring shaft 63, the annular guide groove 65, which is inclined to the left and right and closed at both ends, opens on its outer wall and slides relative to the hemispherical guide block 67 fixed to the inner wall of the treatment tank 2 by the connecting rod 66. The guide block 67 exerts a squeezing effect on the guide groove 65, causing the stirring shaft 63 to move up and down along the axis of the rotating shaft 62 while rotating with the rotating shaft 62. This, in turn, drives the stirring blades 64 to move up and down to stir, improving the uniformity of mixing between the wastewater and the treatment agent, ensuring sufficient reaction, and effectively improving the wastewater treatment effect. After the treatment is completed, the valve on the discharge pipe 5 is opened, and the treated wastewater is discharged through the discharge pipe 5.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
