Technical Field

[0001] The utility model relates to the technical field of lithium iron phosphate production, in particular to a preliminary treatment device for waste water used in lithium iron phosphate production. Background Art

[0002] During the production process of lithium iron phosphate, wastewater containing acidic substances, heavy metal ions, phosphates and other chemical residues will be produced. If these wastewaters are discharged directly without proper treatment, they will not only cause serious pollution to natural water bodies and cause damage to the water ecological balance, but also cause irreversible chemical pollution to the soil, affecting the growth of crops and groundwater safety. In addition, due to its complex composition and high concentration of corrosive substances, operators face the risk of direct exposure when handling such wastewater, which may cause occupational health and safety issues such as skin burns and chemical burns.

[0003] When treating lithium iron phosphate production wastewater, traditional wastewater treatment methods often focus on back-end treatment steps such as chemical neutralization and precipitation separation. However, there is a lack of targeted design for the front-end pretreatment stage, especially how to effectively prevent wastewater splashing caused by operations such as transfer during the treatment process. This not only affects the safety of the working environment, but also increases the difficulty and cost of wastewater treatment, because splashing wastewater may accelerate the corrosion of treatment equipment and increase maintenance frequency, and may also affect the surrounding environment and personnel health.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0019] An embodiment of the present application provides a preliminary treatment device for wastewater used in lithium iron phosphate production. The preliminary treatment device for wastewater used in lithium iron phosphate production effectively prevents wastewater from splashing onto the skin of workers during the treatment process by setting a protective component, including a protective plate, fixing holes, bolts and threaded holes, thereby reducing occupational health risks and improving operational safety.

Figure 1-4 In this embodiment, a preliminary treatment device for wastewater used in lithium iron phosphate production is provided, including: a filter box 1, the filter box 1 is respectively a first filter box 101, a second filter box 102 and a third filter box 103, a protective component is arranged on the top of the filter box 1, for preventing the wastewater in the filter box 1 from splashing onto the skin of the staff, and the protective component includes: a protective plate 2, a fixing hole 21, a bolt 22 and a threaded hole 23.

[0022] Furthermore, two protective plates 2 are both arranged on the top of the filter box 1, and multiple fixing holes 21 are all opened on the top of the protective plates 2, and bolts 22 are respectively arranged inside the multiple fixing holes 21, and threaded holes 23 are opened on the top of the filter box 1. The bottom end of the bolt 22 passes through the fixing hole 21 and extends to the inside of the threaded hole 23, and the bolt 22 is threadedly engaged with the threaded hole 23. The protective plate 2 can block the splashed wastewater to prevent the staff from contacting the wastewater. When the inside of the filter box 1 needs to be cleaned, the bolt 22 can be rotated in the opposite direction. After rotation, the bolt 22 will gradually leave the inside of the threaded hole 23. When the bolt 22 leaves the inside of the threaded hole 23, the fixation of the protective plate 2 is released, so that the protective plate 2 can be removed. When the protective plate 2 is to be installed, the fixing hole 21 can be aligned with the threaded hole 23, and the protective plate 2 is placed after alignment. At this time, the bolt 22 is inserted into the fixing hole 21. After insertion, the bolt 22 is rotated so that the bolt 22 enters the inside of the threaded hole 23, so as to install the protective plate 2.

[0023] Furthermore, two connecting blocks 3 are connected to the inner wall of the filter box 1, and a slide groove 31 is opened on one side of the two connecting blocks 3 corresponding to each other, and an installation frame 32 is arranged between the two connecting blocks 3, and both sides of the installation frame 32 are connected with sliders 33 matching with the slide groove 31, and a handle is connected to the top of the installation frame 32.

After the wastewater enters the first filter box 101, it will pass through the filter screen in the installation frame 32 to filter the wastewater. Because the aperture of the filter screen in the first filter box 101, the second filter box 102 and the third filter box 103 is reduced, it can be In order to filter out the particles and other substances in the wastewater and prevent the particles and other substances from affecting the subsequent membrane filtration, the filter screen needs to be treated with facilities. Grab the handle, and pull it upwards to move the handle with the installation frame 32, so that the installation frame 32 begins to leave the filter box 1. When the installation frame 32 leaves the filter box 1, it is convenient for the user to clean and treat the filter screen. When installing the installation frame 32, align the slider 33 with the slide groove 31. After alignment, place the installation frame 32 so that the slider 33 enters the slide groove 31. After the slider 33 enters the slide groove 31, the installation frame 32 can be fixed to prevent the installation frame 32 from tipping over when filtering the wastewater.

[0024] A first transmission pipe 11 is connected to one side of the first filter box 101, a second transmission pipe 12 is connected to one side of the second filter box 102, one end of the first transmission pipe 11 is communicated with the second filter box 102, one end of the second transmission pipe 12 is communicated with the third filter box 103, a water inlet pipe 13 is connected to one side of the first filter box 101, and a drainage pipe 14 is connected to one side of the third filter box 103. The first transmission pipe 11 can transfer the wastewater in the first filter box 101 to the second filter box 102, so that the wastewater can be further filtered, and the second transmission pipe 12 can transfer the wastewater from the second filter box 102 to the third filter box 103, so that the wastewater can be filtered more deeply, and the water inlet pipe 13 can transfer the untreated wastewater to the inside of the first filter box 101, so as to start preliminary filtering treatment of the wastewater, and the drainage pipe 14 can transfer the wastewater that has undergone preliminary filtration to subsequent treatment processes.
