Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, specifically to an environmentally friendly wastewater treatment device. Background Technology
[0002] With the rapid development of industrialization and urbanization, the amount of sewage generated is increasing day by day, and sewage treatment has become an important part of environmental protection. Among the many sewage treatment processes, filtration and adsorption are common and important treatment steps. In the daily operation of small farms, a large amount of sewage containing feces, feed residue, microorganisms, and high concentrations of organic matter, nitrogen and phosphorus pollutants is generated. At present, the sewage treatment situation of small farms is not optimistic. Most small farms adopt natural discharge or simple treatment methods, such as directly discharging sewage into surrounding ditches, ponds and other water bodies, or simply using sedimentation tanks for preliminary sedimentation. Natural discharge will lead to serious pollution of surrounding water bodies, causing eutrophication, emitting foul odors, damaging the ecological environment, and affecting the lives of surrounding residents.
[0003] In practical applications, it has been found that charcoal has a certain porous structure and specific surface area, which can adsorb some organic matter, pigments and odor substances in sewage, and play a certain role in improving water quality. For example, it can adsorb some organic substances with color and odor in sewage, so that the color and odor of sewage can be improved to a certain extent. Compared with some professional adsorbents such as activated carbon, charcoal is cheaper and has a wide range of sources. Small farms can make their own charcoal using waste wood and other raw materials to reduce sewage treatment costs.
[0004] However, charcoal in its natural state varies in size, and the contact area between the larger volume of charcoal placed in the treatment tank and the sewage is relatively small. This reduces the probability that odor molecules will effectively contact and be adsorbed by the charcoal. Due to the small contact area, the amount of sewage that can be treated per unit time is limited, resulting in low overall sewage treatment efficiency. Therefore, an environmentally friendly sewage treatment device is proposed to address the above problems. Utility Model Content
[0005] The purpose of this invention is to provide an environmentally friendly wastewater treatment device to solve the problem that the relatively small contact area between the large volume of charcoal placed in the treatment tank and the wastewater reduces the probability of odor molecules effectively contacting and being adsorbed by the charcoal. Due to the small contact area, the amount of wastewater that can be treated per unit time is limited, resulting in low overall wastewater treatment efficiency.
[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0029] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0031] Please see Figure 1-6 This utility model provides a technical solution:
[0032] An environmentally friendly wastewater treatment device includes a wastewater tank 1, a support 2 fixedly connected to the outside of the wastewater tank 1, a screw control mechanism 3 threadedly connected to the center of the support 2, and a pressure application component 4 installed below the screw control mechanism 3; the pressure application component 4 includes a pressure plate 41, a pressure rod 42 fixedly connected to one side of the pressure plate 41, and a pressure plate mechanism 43 installed below the pressure plate 41; the pressure plate mechanism 43 includes a pressure plate body 431, a water inlet groove 432 is formed on the surface of the pressure plate body 431, a toothed nail 433 is fixedly connected to the bottom end of the pressure plate body 431, a toothed claw 434 is fixedly connected to the outside of the toothed nail 433, guide grooves 435 and drain holes 436 are formed on both sides of the middle part of the pressure plate body 431, the drain holes 436 are located at the center of the guide grooves 435, a limiting seat 437 is slidably connected to the inner side of the guide grooves 435, and a limiting groove 5 adapted to the limiting seat 437 is formed on the bottom of the inner side of the wastewater tank 1.
[0033] As a further implementation of this solution, the pressure bar 42 and the pressure plate 41 are located on the same horizontal line. The outer side of the pressure bar 42 has an arc-shaped structure, and the lower surface of the pressure bar 42 is in contact with the upper surface of the pressure plate body 431, which can directly and effectively transmit the applied force to the pressure plate body 431 and enhance the pressure effect.
[0034] As a further implementation of this scheme, a protective plate 44 is hinged to the inner side of the guide groove 435. The protective plate 44 is located above the limit seat 437. The two protective plates 44 are arranged symmetrically from left to right. The outer shape of the protective plate 44 is adapted to the inner shape of the guide groove 435. Its main function is to prevent impurities in the sewage from entering the sliding connection between the guide groove 435 and the limit seat 437 during the operation of the device, so as to avoid impurities affecting the normal sliding of the limit seat 437, thereby ensuring the stable operation of the pressure plate mechanism 43.
[0035] As a further implementation of this solution, a connecting plate 45 is fixedly connected to the center of the top of the pressure plate body 431. Limiting blocks 46 are fixedly connected to both sides of the bottom of the connecting plate 45. When the pressure plate 41 rotates, the limiting blocks 46 slide in the movable groove 48 to ensure that the pressure plate body 431 can rotate synchronously with the pressure plate 41, thereby achieving effective crushing of charcoal.
[0036] As a further implementation of this solution, a connecting groove 47, two movable grooves 48, and two inclined sliding grooves 49 are provided at the center of the bottom end of the pressure plate 41. The two movable grooves 48 are located on both sides of the connecting groove 47, and the inclined sliding grooves 49 are located at one end of the movable grooves 48. The limiting block 46 is slidably connected to the movable grooves 48. A magnetic block 6 is fixedly connected to the inner side of the connecting groove 47. The magnetic block 6 is located above the limiting block 46, and the magnetic block 6 and the limiting block 46 are magnetically attracted to each other. During normal pressure application, the magnetic attraction ensures the connection stability between the limiting block 46 and the pressure plate 41. This allows the pressure plate 41 to drive the pressure plate body 431 to rotate synchronously. The two movable grooves 48 are located on both sides of the connecting groove 47, providing sliding space for the limit block 46. The inclined slide groove 49 is located at one end of the movable groove 48. When the pressure is applied, the screw control mechanism 3 reverses and the pressure plate 41 begins to move upward. At this time, the pulling force of the screw control mechanism 3 on the pressure plate 41 is greater than the magnetic attraction force between the magnetic block 6 and the connecting plate 45. The limit block 46 first rotates along the path of the movable groove 48 and then slides out smoothly through the inclined slide groove 49, realizing the rapid separation between the pressure plate 41 and the pressure plate mechanism 43.
[0037] As a further implementation of this solution, the vertical cross-section of the limiting seat 437 is a right trapezoid. A spring telescopic rod 438 is installed at the rear end of the limiting seat 437. The rear end of the spring telescopic rod 438 is fixedly connected to one end of the inner side of the movable groove 48. A feeding groove 439 is opened on one side of the top of the pressure plate body 431. The inner side of the feeding groove 439 is connected to the inner side of the sewage tank 1. The feeding groove 439 is located in the middle between the pressure plate 41 and the pressure rod 42, which makes it convenient for the staff to add charcoal. The staff only needs to open the sealing plug in the feeding groove 439 to add an appropriate amount of charcoal into the sewage tank 1 through the feeding groove 439.
[0038] Workflow: Before use, rotate the screw control mechanism 3 in the reverse direction to move the lower pressure component 4 upward. The feeding trough 439, located between the pressure plate 41 and the pressure rod 42, facilitates the addition of charcoal. By opening the sealing plug inside the feeding trough 439, an appropriate amount of charcoal is added to the sewage tank 1. After addition, rotate the screw control mechanism 3 clockwise. The pressure component 4 will then move clockwise downward along the path of the screw control mechanism 3. When the pressure plate body 431 descends with the lower screw control mechanism 3 to contact the charcoal, the evenly distributed toothed spikes 433 on the lower surface of the pressure plate body 431 begin to function. As the pressure plate body 431 continues to press down and rotate, the toothed spikes 433 gradually insert into the charcoal. Inside, the sharp structure of the pressure plate body 431 and the toothed nail 433 of the pressure plate is used to cut large pieces of charcoal. The toothed claws 434 on the outside of the toothed nail 433 make it easy to break the charcoal into small pieces. The pressure plate 41 and the pressure rod 42 are responsible for providing sufficient pressure to the upper surface of the pressure plate body 431. When the pressure plate body 431 moves to the position of the limiting groove 5, the limiting seat 437 on the inner side of the guide groove 435 can automatically embed the front end of the limiting seat 437 into the pre-set limiting groove 5 in the sewage tank 1 by relying on the elastic force of the spring telescopic rod 438. At this time, the pressure plate stops descending. The height of the pressure plate mechanism 43 can be accurately limited by the setting limiting groove 5 to avoid excessive pressure from damaging the sewage tank 1 and to ensure the stability and safety of the device operation.
[0039] It needs to be added that during the pressing process, the limiting blocks 46 on both sides of the connecting plate 45 will abut against the front end of the movable groove 48, and the pressure plate 41 can drive the pressure plate body 431 to rotate synchronously. When the pressure is completed, the screw control mechanism 3 reverses and the pressure plate 41 begins to move upward. At this time, the pulling force of the screw control mechanism 3 on the pressure plate 41 is greater than the magnetic attraction force between the magnetic block 6 and the connecting plate 45. The limiting block 46 first rotates along the path of the movable groove 48 and then slides out smoothly through the inclined slide groove 49, so that the pressure plate 41 and the pressure plate mechanism 43 can be quickly separated. The screw control mechanism 3 drives the pressure plate 41 and the pressure rod 42 to move upward. The pressure plate mechanism 43 is in the sewage tank 1 and can continue to limit the crushed charcoal. The sewage has a certain impact force during the flow. If there is no pressure plate mechanism 43 to limit it, the crushed charcoal may float or shift due to the impact of the sewage, resulting in uneven contact between it and the sewage, which reduces the adsorption efficiency. At this time, the sewage flows from the sewage tank 1 The wastewater flows into the inlet and enters the wastewater tank 1 through the inlet trough 432. The wastewater is fully exposed to the crushed charcoal, which adsorbs odor molecules in the wastewater. The treated wastewater is then discharged from the outlet of the wastewater tank 1.
[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
