Description

Technical Field

[0001] This utility model relates to the field of mixing device technology, specifically a wastewater treatment agent mixing device for industrial wastewater treatment. Background Technology

[0002] During industrial production, a large amount of industrial wastewater is generated. Industrial wastewater contains impurities such as suspended solids, organic matter, heavy metals, nitrogen and phosphorus, and oils. Depending on the nature of the different impurities, appropriate reagents are selected to purify the wastewater so that the treated industrial wastewater meets environmental discharge requirements.

[0003] For pharmaceutical preparation, existing technologies use pharmaceutical devices consisting of a pharmaceutical tank, a stirring rod, and a drive motor. However, the pharmaceutical solution is mainly transported through a pipe, and the feeding end of the pipe is fixedly connected to the pharmaceutical tank. Therefore, the position of the pharmaceutical solution inside the pharmaceutical tank does not change. When the stirring rod is used to mix the pharmaceutical solution with water, the concentration of the prepared pharmaceutical solution varies in different parts of the pharmaceutical tank. Furthermore, due to the height difference between the feeding port and the inside of the pharmaceutical tank, the pharmaceutical solution may splash back, resulting in some waste. To address the shortcomings of existing technologies, we propose a wastewater treatment agent mixing device for industrial wastewater treatment to solve the above problems. Utility Model Content

Therefore, the position of the agent inside the pharmaceutical container does not change. Later, when the stirring rod is used to mix the agent with water, the concentration of the agent varies in different parts of the pharmaceutical container. Furthermore, due to the height difference between the agent feeding port and the inside of the pharmaceutical container, the agent may splash back, resulting in waste of some agent.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] This application provides a wastewater treatment agent mixing device for industrial wastewater treatment, which solves the problem that the agent is mainly transported through a pipe, and the feeding end of the pipe is in a fixed connection with the pharmaceutical container. Therefore, the position of the agent inside the pharmaceutical container does not change. Later, when the agent is mixed with water and other substances using a stirring rod, the concentration of the agent prepared in different parts of the pharmaceutical container is different. In addition, due to the height difference between the agent feeding port and the inside of the pharmaceutical container, the agent will splash back, causing some agent waste. This device achieves uniform feeding of the agent.

[0028] 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.

[0029] This utility model discloses a wastewater treatment agent mixing device for industrial wastewater treatment.

[0030] According to the appendix Figure 1-6 As shown, the assembly includes an assembly frame 1, a pharmaceutical barrel 2 fixedly mounted on the inner surface of the assembly frame 1, a barrel cover 3 covering the top surface of the pharmaceutical barrel 2, a stirring rod 4 rotatably mounted inside the pharmaceutical barrel 2, a drive motor 5 fixedly mounted on the top surface of the barrel cover 3 for driving the stirring rod 4 to rotate, a feeding pipe 6 and a discharging pipe 61 mounted on one side of the assembly frame 1. A control pump is installed on one side of the assembly frame 1, and the control pump is connected to the feeding pipe 6, which can transport the liquid medicine to the inside of the pharmaceutical barrel 2 through the feeding pipe 6. One end of the feeding pipe 6 and the discharging pipe 61 are connected to the inside of the pharmaceutical barrel 2. One end is connected to the industrial wastewater treatment tank. Specifically, when preparing the wastewater treatment agent, the required raw materials and water are fed into the pharmaceutical tank 2 through multiple sets of feeding pipes 6. Then, the drive motor 5 is turned on, so that the drive motor 5 controls the stirring rod 4 to mix the raw materials and water, thereby forming the required wastewater treatment agent. Subsequently, the prepared wastewater treatment agent is transported into the industrial wastewater treatment tank through the discharge pipe 61 via the pump body, etc. (not specifically shown in the attached figure), so as to treat the wastewater.

[0031] See attached document Figure 2-5A drug dispensing mechanism is provided at one end of the stirring rod 4 near the drive motor 5. Through the drug dispensing mechanism, the raw materials of the medicine are evenly fed into the inside of the pharmaceutical barrel 2 in the circumferential direction, accelerating the mixing efficiency between the raw materials of the medicine. The drug dispensing mechanism includes a hollow cylinder 7, which is fixedly connected to the top surface of the stirring rod 4 and to the motor shaft of the drive motor 5. That is, the hollow cylinder 7 is fixedly set between the stirring rod 4 and the motor shaft of the drive motor 5. The inner wall of the barrel cover 3 is fixedly connected with an annular opening for the feeding pipe 6 to communicate with the inside of the hollow cylinder 7. A hollow base 71 and a hollow cylinder 7 are fixedly connected to a connecting bearing 72 on the outer wall of one end of the hollow base 71. That is, the outer wall of the hollow cylinder 7 is fixedly connected to the inner wall of the connecting bearing 72, and the outer wall of the connecting bearing 72 is fixedly connected to the bottom surface of the hollow base 71. A through hole 711 is opened on the outer wall of one end of the hollow cylinder 7 near the hollow base 71. The feeding pipe 6 is connected to the inside of the hollow cylinder 7 through the hollow base 71 and the through hole 711. A sealing element can be set at the connection position between the hollow base 71 and the hollow cylinder 7 to prevent raw material leakage.

[0032] See attached document Figure 4-5 An extension tube 73 is fixedly installed on the outer wall of one end of the hollow cylinder 7 that extends into the pharmaceutical barrel 2. An intelligent rotating nozzle 74 is installed at one end of the extension tube 73. A buffer plate 75 is fixedly connected to the bottom surface of the hollow cylinder 7 and is located below the intelligent rotating nozzle 74. The intelligent rotating nozzle 74 is inclinedly installed on the bottom surface of one end of the extension tube 73. The buffer plate 75 is inclinedly installed below the intelligent rotating nozzle 74. Multiple sets of guide grooves 76 are opened on the top surface of the buffer plate 75. The buffer plate 75 is located above the highest liquid level inside the pharmaceutical barrel 2. When the intelligent rotating nozzle 74 sprays the liquid at an angle, the liquid contacts the buffer plate 75 with an oblique trajectory. At this time, the droplets will slide down along the surface of the buffer plate 75 instead of rebounding, which can reduce the amount of liquid splashing. The guide grooves 76 are opened on the surface of the buffer plate 75 to further reduce the liquid splashing.

[0033] See attached document Figure 2 and attached Figure 6 The auxiliary component 8 is disposed on the outer wall of one end of the extension tube 73. The auxiliary component 8 includes an auxiliary scraper 81 for scraping the precipitated drug on the inner wall of the pharmaceutical container 2 and a mounting screw 83 for fixing the auxiliary scraper 81 to the outer wall of one end of the extension tube 73. A mounting seat 82 for positioning and inserting one end of the auxiliary scraper 81 is fixedly connected to the outer wall of one end of the extension tube 73. The mounting screw 83 is rotatably disposed on one side of the mounting seat 82. The auxiliary scraper 81 is composed of multiple scrapers. The scrapers are made of corrosion-resistant and acid-resistant materials. The shape of the multiple scraper groups is determined according to the inner wall of the pharmaceutical container 2 to ensure that the auxiliary scraper 81 can scrape the drug precipitate adhering to the inner wall and bottom surface of the pharmaceutical container 2.

[0034] Specifically, when the drive motor 5 is turned on, it drives the hollow cylinder 7 and the stirring rod 4 to rotate synchronously. At this time, the hollow cylinder 7 rotates along the inner surface of the annular hollow seat 71 under the limiting position of the connecting bearing 72. During this process, before the liquid medicine is fed into the pharmaceutical tank 2 through a set of feeding pipes 6, it first enters the interior of the annular hollow seat 71, which is connected to the end of the set of feeding pipes 6. Then, it enters the interior of the hollow cylinder 7 through the through hole 711, and then enters the interior of the extension pipe 73 equipped with the intelligent rotating nozzle 74 through the hollow cylinder 7. The intelligent rotating nozzle 74 sprays the liquid medicine onto the surface of the buffer plate 75, and then the liquid medicine flows along the surface of the buffer plate 75 into the interior of the pharmaceutical tank 2, where it mixes with the water added to the pharmaceutical tank 2 to adjust the concentration of the medicine. In particular, since the extension pipe 73 with the intelligent rotating nozzle 74 is fixedly connected to the hollow cylinder 7, the intelligent rotating nozzle 74 rotates circumferentially inside the pharmaceutical tank 2 with the hollow cylinder 7 as the axis, so as to evenly feed the liquid medicine into the pharmaceutical tank 2.

[0035] In addition, when the extension tube 73 equipped with the intelligent rotating nozzle 74 rotates with the hollow cylinder 7, it will synchronously drive the auxiliary scraper 81 fixedly connected to the extension tube 73 to rotate in a circle, so that the auxiliary scraper 81 can scrape the medicine sediment adhering to the inner side wall and inner bottom surface of the medicine barrel 2, thereby fully mixing the medicine and water.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
