Description

A device for deep treatment of electroplating wastewater

Technical Field

The utility model relates to the field of wastewater treatment devices, in particular to a device for deep treatment of electroplating wastewater.

Background Art

Electroplating is the process of plating a thin layer of other metals or alloys on certain metal surfaces using the principle of electrolysis. It is a process that uses electrolysis to adhere a layer of metal film to the surface of metal or other material parts, thereby preventing metal oxidation (such as corrosion), improving wear resistance, conductivity, reflectivity, corrosion resistance and enhancing aesthetics. Liquids such as electroplating solution are needed during electroplating. After electroplating, the wastewater generated by electroplating will be discharged, but the electroplating wastewater will contain harmful components. In order to avoid polluting the environment, the electroplating wastewater must be treated before it can be discharged, and thus a wastewater treatment device is required.

Most of the treatment devices currently used are purification treatment boxes, which neutralize harmful substances in wastewater by adding chemical reagents to react with wastewater. However, when chemical reagents are added to produce chemical reactions, certain solid substances will precipitate in the wastewater. In order to prevent the discharged solid substances from clogging the pipeline, a filter is generally placed at the bottom of the liquid outlet of the treatment box to filter the fixed substances. However, since the precipitated fixed substances have fine particles, the solid substances are very easy to accumulate on the filter or clog the filter, so that the treated wastewater cannot be quickly discharged through the filter, which reduces the discharge treatment efficiency and is very inconvenient to use.

A soft brush can be set below the cleaning plate 9, which can effectively push the fixed object to move while clearing the filter hole, and a liquid outlet funnel 10 is connected to the bottom of the mounting frame 6, and the reciprocating screw rod 8 and the auxiliary slide bar 19 are respectively located on the front and back sides below the liquid outlet pipe 11.

The first motor 12 drives the reciprocating screw 8 to rotate. Since the auxiliary slide bar 19 limits the rotation of the cleaning plate 9, as the reciprocating screw 8 rotates, the cleaning plate 9 moves back and forth along the reciprocating screw 8, thereby scraping the fixed objects on the filter screen 7 to the left and right sides of the filter screen 7 for accumulation, and at the same time clearing the filter holes.

The mounting frame 4 is slidably connected to a limit rod 14, the mounting frame 6 is provided with a limit hole 13, the limit rod 14 is connected to a control board 15, the limit rod 14 is sleeved with a spring 16, both ends of the spring 16 are respectively connected to the control board 15 and the mounting frame 4, a plurality of groups of limit rods 14 are provided, and the plurality of groups of limit rods 14 are all connected to the control board 15, the stability of the connection between the mounting frame 6 and the mounting frame 4 is improved by a plurality of groups of limit rods 14, and limit rods 14 are provided on both the left and right sides of the mounting frame 4.

As shown in Figure 1, at this time, the mounting bracket 6 is connected to the mounting frame 4, and the solid matter in the liquid can be filtered through the filter screen 7. When the filter screen 7 needs to be removed, the control board 15 is pulled outward to drive the limit rod 14 to slide out of the limit hole 13, and the spring 16 is compressed at the same time, so that the mounting bracket 6 can be quickly taken out downward. During installation, it is only necessary to move the mounting bracket 6 upward, pull the control board 15 outward, and then continue to move the mounting bracket 6 upward. When the limit hole 13 reaches the limit rod 14, the limit rod 14 can be automatically inserted into the limit hole 13 under the action of the restoring force of the spring 16 to complete the installation.

The specific implementation process is as follows:

The piston head 5 is aligned with the liquid outlet pipe 11, and the piston head 5 is controlled to move upward by the cylinder 18 to insert the piston head 5 into the liquid outlet pipe 11, thereby closing the liquid outlet pipe 11, adding wastewater into the treatment box 2, adding corresponding chemical reagents from the dosing port, and driving the stirring rod 3 to stir the wastewater by the driving motor 20 so that the wastewater and the chemical reagents are quickly mixed and evenly mixed. After the wastewater is treated, the piston head 5 is controlled to move downward by the cylinder 18 to open the liquid outlet pipe 11, and the piston head 5 moves downward. The second motor 17 immediately drives the cylinder 18 to rotate, thereby causing the piston head 5 to turn away from the liquid outlet pipe 11. The treated liquid is discharged from the liquid outlet pipe 11, and is discharged from the liquid outlet funnel 10 after filtering the solid matter through the filter screen 7. The cleaning plate 9 is driven by the first motor 12 to scrape the solid matter on the filter screen 7 to both sides, so as to maintain the passing stability of the middle part of the filter screen 7. After using it for a period of time, the mounting frame 6 can be quickly removed, the solid matter collected by the filter screen 7 can be centrally processed, and then the clean filter screen 7 can be installed. After using it for a period of time, the box cover 1 can also be removed, the stirring rod 3 can be unscrewed, and the stirring rod 3 and the processing box 2 can be cleaned separately, so as to facilitate the subsequent use of the device.

The filter screen 7 of the present technical solution is connected to the mounting frame 4 through the mounting bracket 6 and is located below the liquid outlet pipe 11, which is convenient for filtering the precipitated fixed matter. The liquid outlet pipe 11 adopts a piston sealing method, which is not easy to be blocked, thereby improving the stability of the liquid outlet; the first motor 12 can drive the cleaning plate 9 to move back and forth left and right, thereby scraping the solid matter accumulated on the filter screen 7 to the two sides of the filter screen 7 for accumulation, thereby maintaining the middle part of the filter screen 7 to always maintain stable filtration, so that the treated liquid can quickly pass through the filter screen 7, and can also better filter the solid matter, avoiding the problem that a large amount of solid matter is attached to the top of the filter screen 7, causing the filter screen 7 to be blocked and the liquid cannot pass smoothly, thereby greatly improving the efficiency and effect of the device in treating wastewater.
