Description

Technical Field

[0001] This utility model relates to a batch processing equipment for cold rolling wastewater, belonging to the technical field of treatment equipment. Background Technology

[0002] Cold rolling wastewater refers to the wastewater generated during the production of cold-rolled steel. It contains a large amount of harmful substances such as grease, heavy metal ions, and suspended solids. Cold rolling is an important step in steel production, mainly used to produce steel products with high precision and good surface quality. It is widely used in high-end products such as automobile manufacturing, electrical products, aviation, precision instruments, and construction. Sequencing batch reactors are used to treat cold rolling wastewater.

[0003] Chinese patent publication (publication number: CN 202201763 U) discloses a batch processing wastewater treatment device. The device includes a housing, with a motor reducer at the top. The output shaft of the reducer extends downwards into the main reaction zone inside the housing. A stirring blade is located at the top of the output shaft. The upper half of the housing contains a quartz sand filtration zone and an activated carbon adsorption zone separated from each other. Filter caps are located at the bottom of both zones. This invention integrates chemical mixing reaction, flocculation reaction, gravity sedimentation, sand filtration, and activated carbon adsorption into one unit, reducing initial investment costs. The batch processing technology is flexible, reducing maintenance and personnel expenses. It fully utilizes the gravity flow characteristics of water, significantly reducing operating costs.

[0004] The height of the stirring blades in the above-mentioned device is relatively fixed. Lime is used in the treatment of cold rolling wastewater because the cold rolling wastewater has high calcium hardness. By adding lime as a neutralization measure, the calcium hardness in the wastewater can be reduced to meet the process requirements. However, since the height of the stirring blades cannot be adjusted, the stirring blades may not be able to mix the lime with the cold rolling wastewater at different heights. This may result in the lime and cold rolling wastewater not being mixed evenly, which in turn affects the treatment of cold rolling wastewater.

[0005] Therefore, a batch processing device for cold rolling wastewater is proposed. Utility Model Content

[0006] In view of this, the present invention provides a batch processing equipment for cold rolling wastewater to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

The slider 205 has two connecting rods 203, the other ends of which are movably connected to the left and right sides of the rear side of the slider 205. A fixed frame 206 is fixedly installed at the bottom of the slider 205. The stirring motor 207 is located on the surface of the fixed frame 206. A connecting rod 208 is movably connected to the bottom of the fixed frame 206. A stirring blade 209 is fixedly installed at the bottom of the connecting rod 208. The oil cylinder 201 is fixedly installed at the rear side of the top of the mounting frame 1. The moving plate 202 is fixedly installed at the front side of the oil cylinder 201. The stirring motor 207 is fixedly installed on the surface of the fixed frame 206. The top of the connecting rod 208 is fixedly installed at the output end of the bottom of the stirring motor 207.

[0030] By setting the adjustment component 2, the fixed frame 206 drives the stirring blade 209 to move up and down through the extension of the oil cylinder 201. By adjusting the height of the stirring blade 209, the stirring blade 209 can mix and stir different heights in the inner cavity of the box 3, thereby improving the mixing effect and uniformity of lime and cold rolling wastewater. At the same time, after the stirring blade 209 has been used for a long time, it can also be removed from the inner cavity of the box 3 to facilitate the cleaning of the substances adhering to its surface, making it convenient for operators to use.

[0031] Example 2

[0032] like Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, in one embodiment, the top left and right sides of the mounting bracket 1 are provided with sliding grooves 210, the bottom left and right sides of the movable plate 202 are slidably connected to the inner cavity of the two sliding grooves 210, the top of the mounting bracket 1 is fixedly installed with a limiting bracket 211, the left and right sides of the slider 205 are slidably connected to the inner side of the limiting bracket 211, the top of the mounting bracket 1 is provided with slots 212, the fixing bracket 206 passes through the inner cavity of the two slots 212 and extends to the inner side of the mounting bracket 1, the inner side of the two cover plates 4 is provided with slots 5, the connecting rod 208 passes through the inner cavity of the slots 5 and extends to the inner cavity of the box 3, the top of the two cover plates 4 is threaded with mounting bolts 6, and the bottom of the mounting bolts 6 is threaded to the inner surface of the box 3.

[0033] By setting the slide groove 210, the movement of the movable plate 202 can be limited to prevent it from deviating during movement, thus affecting the adjustment of the height of the stirring blade 209. By setting the limit frame 211, the movement of the slider 205 can be limited to prevent it from deviating during movement, thus affecting the adjustment of the height of the stirring blade 209. By setting the slot 212, the movement of the fixed frame 206 can be limited to prevent it from deviating during movement, thus affecting the mixing of cold rolling wastewater at different heights. By setting the slot 5, the movement of the connecting rod 208 can be limited to ensure the accuracy of the moving direction of the connecting rod 208. By setting the mounting bolt 6, the cover plate 4 can be installed, facilitating the cleaning of the inner cavity of the box 3.

[0034] In operation, this invention works as follows: First, lime is poured into the inner cavity of the box 3. Then, the cover plate 4 is installed on the top of the box 3 using the mounting bolts 6. At this time, the output of the stirring motor 207 drives the connecting rod 208 to drive the stirring blade 209 to stir, thereby mixing the lime with the cold rolling wastewater in the inner cavity of the box 3. At this time, the extension and retraction of the oil cylinder 201 causes the moving plate 202 to move back and forth. With the cooperation of the connecting rod 203, the slider 205 drives the fixed frame 206 to move up and down. At this time, the fixed frame 206 simultaneously drives the connecting rod 208 and the stirring blade 209 to move up and down, thereby causing the stirring blade 209 to stir and mix the cold rolling wastewater and lime in the inner cavity of the box 3, thus achieving the treatment of cold rolling wastewater.
