Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and in particular relates to a wastewater treatment device for environmental protection. Background Technology

[0002] In daily life and factory production, a large amount of wastewater is generated every day. In order to avoid the wastewater from polluting the environment, the wastewater is treated. The treatment equipment reduces the harmful substances in the wastewater significantly, thereby preventing it from polluting the soil and other environments. At the same time, the reduction of harmful substances in the wastewater can improve the polluted ecological environment to a certain extent.

[0003] In wastewater treatment, flocculants are added to reduce the solids content of the wastewater. After flocculation, the wastewater is filtered to separate the flocculants from the wastewater. However, during the filtration process, excessive flocculants can easily clog the filter screen, affecting filtration efficiency. Furthermore, the filtered flocculants contain a large amount of water, making them inconvenient to transport and affecting subsequent treatment. To solve these problems, there is an urgent need for an environmentally friendly wastewater treatment device. Utility Model Content

[0004] The purpose of this invention is to address the problems encountered in wastewater treatment, where flocculants are added to reduce the solid content of wastewater, followed by filtration to separate the flocculants from the wastewater. However, excessive flocculants can clog the filter screen and affect filtration efficiency. Furthermore, the filtered flocculants contain a large amount of water, making them difficult to transport and impacting subsequent treatment. Therefore, this invention proposes an environmentally friendly wastewater treatment device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a wastewater treatment device for environmental protection, comprising a water tank, an outlet on one side of the water tank, a filter assembly at the top of the water tank, and a drying assembly on one side of the water tank;

[0006] The filter assembly includes a filter tank with a filter screen at the bottom and a mounting base fixedly connected to the top of the filter tank. A rotating rod is rotatably connected to the mounting base through a through hole. A motor is fixedly connected to one end of the rotating rod, and a connecting rod is fixedly connected to the outer wall of the rotating rod. A mesh plate is fixedly connected to the bottom end of the connecting rod.

[0007] As a further description of the above technical solution:

[0008] The bottom of the filter tank is fixedly connected to the top of the water tank, and a support plate is fixedly connected to one side of the filter tank. The top surface of the support plate is fixedly connected to the motor.

[0009] As a further description of the above technical solution:

[0010] The end of the rotating rod away from the motor is fixedly connected to a second pulley, the outer wall of the second pulley is provided with a belt, and one side of the filter tank is provided with a bevel.

[0011] As a further description of the above technical solution:

[0012] The drying assembly includes a support frame, a receiving trough is slidably connected to the support frame through a groove opened therein, and a conveying hopper is fixedly connected to one side of the top of the support frame.

[0013] As a further description of the above technical solution:

[0014] One end of the conveying hopper is fixedly connected to the bevel on one side of the filter tank, and the top of the support frame is fixedly connected to the outer shell, and the top of the outer shell is fixedly connected to the heating mesh plate.

[0015] As a further description of the above technical solution:

[0016] The outer casing is rotatably connected to an impeller through through holes on both sides. One end of the impeller shaft is fixedly connected to a first pulley, and the outer wall of the first pulley is in close contact with the belt.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0018] 1. In this utility model, a mesh plate is installed inside. When filtering wastewater after flocculation, the wastewater is poured into the filter tank and filtered through the filter screen at the bottom, allowing the wastewater to flow into the water tank. At the same time, the motor is started, and the output shaft of the motor rotates, driving the rotating rod to rotate. This, in turn, moves the mesh plate within the filter tank via the connecting rod. The mesh plate then moves impurities to one side of the filter tank, allowing them to slide off the bevel and into the drying assembly. This design effectively cleans the impurities filtered out of the filter tank, allowing them to slide off the bevel on one side of the filter tank. This reduces the amount of impurities in the filter tank, preventing excessive impurities from clogging the filter screen and affecting filtration efficiency. It also effectively ensures the filtration effect of the filter tank.

[0019] 2. In this utility model, a heating mesh plate is installed inside. When impurities fall into the receiving trough, the heating mesh plate is activated. At the same time, the rotation of the rotating rod drives the second pulley to rotate, which in turn drives the first pulley and impeller to rotate through the belt, generating airflow. The airflow blows the heat emitted by the heating mesh plate onto the impurities in the receiving trough. This design dries the impurities in the receiving trough, thereby reducing their moisture content and facilitating their transportation and processing. It avoids situations where excessive moisture makes transportation and processing difficult, thus benefiting the treatment of impurities. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-4 This utility model provides a technical solution: a wastewater treatment device for environmental protection, including a water tank 1, an outlet 2 on one side of the water tank 1, a filter assembly 4 at the top of the water tank 1, and a drying assembly 3 on one side of the water tank 1.

[0028] The filter assembly 4 includes a filter tank 48, a filter screen 47 at the bottom of the filter tank 48, and a mounting base 49 fixedly connected to the top of the filter tank 48. A rotating rod 42 is rotatably connected to the mounting base 49 through a through hole therein. A motor 41 is fixedly connected to one end of the rotating rod 42, and a connecting rod 43 is fixedly connected to the outer wall of the rotating rod 42. A mesh plate 45 is fixedly connected to the bottom end of the connecting rod 43.

[0029] The bottom end of the filter tank 48 is fixedly connected to the groove at the top of the water tank 1. A support plate 410 is fixedly connected to one side of the filter tank 48. The top surface of the support plate 410 is fixedly connected to the motor 41. A second pulley 44 is fixedly connected to the end of the rotating rod 42 away from the motor 41. A belt 46 is provided on the outer wall of the second pulley 44. A bevel is provided on one side of the filter tank 48.

[0030] The specific implementation method is as follows: When filtering the wastewater after flocculation, it is poured into the filter tank 48 and filtered through the filter screen 47 at the bottom, so that the wastewater flows into the water tank 1. At the same time, the motor 41 is started. The output shaft of the motor 41 rotates and drives the rotating rod 42 to rotate. The rotating rod 42 drives the connecting rod 43 to rotate and drives the screen plate 45 to move in the filter tank 48. The screen plate 45 drives the filtered impurities to one side of the filter tank 48 and causes the impurities to slide from the bevel into the drying component 3.

[0031] The drying assembly 3 includes a support frame 36, a receiving trough 37 slidably connected to the support frame 36 through a groove opened therein, a conveying hopper 34 fixedly connected to one side of the top of the support frame 36, one end of the conveying hopper 34 fixedly connected to a bevel on one side of the filter tank 48, a housing 31 fixedly connected to the top of the support frame 36, a heating mesh plate 35 fixedly connected to the top of the housing 31, an impeller 32 rotatably connected to the housing 31 through through holes opened on both sides, a first pulley 33 fixedly connected to one end of the shaft of the impeller 32, and the outer wall of the first pulley 33 in close contact with the belt 46.

[0032] The specific implementation method is as follows: when impurities fall into the receiving trough 37, the heating mesh plate 35 is activated. At the same time, the rotation of the rotating rod 42 drives the second pulley 44 to rotate, which in turn drives the first pulley 33 to rotate through the belt 46. The rotation of the first pulley 33 drives the impeller 32 to rotate and generate airflow. At the same time, the airflow blows the heat emitted by the heating mesh plate 35 towards the impurities in the receiving trough 37.

[0033] Working principle: When filtering wastewater after flocculation, it is poured into the filter tank 48 and filtered through the filter screen 47 at its bottom, allowing the wastewater to flow into the water tank 1. Simultaneously, the motor 41 is started, and the output shaft of the motor 41 rotates, driving the rotating rod 42 to rotate. This, in turn, drives the connecting rod 43 to rotate, causing the screen plate 45 to move within the filter tank 48. The screen plate 45 then moves the filtered impurities to one side of the filter tank 48, causing them to slide from the bevel onto the surface of the conveying hopper 34 and fall into the receiving trough 37 in the support frame 36. When impurities fall into the receiving trough 37, the heating mesh plate 35 is activated. At the same time, the rotation of the rotating rod 42 drives the second pulley 44 to rotate, which in turn drives the first pulley 33 to rotate via the belt 46. Since the first pulley 33 and the second pulley 44 are different sizes, their rotation speeds are different. The appropriate rotation speed can be obtained by changing the size ratio of the first pulley 33 and the second pulley 44. The rotation of the first pulley 33 drives the impeller 32 to rotate and generate airflow. At the same time, the airflow blows the heat emitted by the heating mesh plate 35 toward the impurities in the receiving trough 37.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
