Abstract

The utility model discloses an electroplating wastewater pretreatment device, which particularly relates to the technical field of electroplating wastewater treatment. The utility model solves the problem that the existing electroplating wastewater treatment device is inconvenient to clean and replace a filter screen.

Description

Electroplating wastewater pretreatment device

Technical Field

The utility model belongs to the technical field of electroplating wastewater treatment, and particularly relates to an electroplating wastewater pretreatment device.

Background

The electroplating process is a process of plating metal on the surface of a product by an electrolysis method, and commonly used processes include nickel plating, chromium plating, zinc plating, cadmium plating and the like, the application of the electroplating process is more and more widespread, and the large discharge of electroplating wastewater can cause heavy metal accumulation and cause pollution of water resources and soil, so that the electroplating wastewater needs to be effectively treated.

When electroplating wastewater is treated, a filtering procedure is adopted, a filter screen is easy to block during filtering, the filtering efficiency is affected, the filter screen is required to be cleaned and replaced, the conventional cleaning and replacement are required to be stopped, and the treatment progress is easy to be affected.

Disclosure of Invention

The utility model provides an electroplating wastewater pretreatment device, which aims to solve the problem that the existing electroplating wastewater treatment device is inconvenient to clean and replace a filter screen.

The technical aim of the utility model is realized by the following technical scheme: the utility model provides an electroplating wastewater pretreatment device, includes the jar body, the intercommunication has the feed liquor pipe on the lateral wall of the jar body, the top fixedly connected with of the jar body two bracing pieces that set up side by side, two common fixedly connected with driving motor on the bracing piece, fixedly connected with is located the inside (mixing) shaft of jar on driving motor's the output shaft, two can dismantle on the bracing piece and be connected with a plurality of filter screens, install the cat ladder on the lateral wall of the jar body, install the backup pad between the top of cat ladder and the bracing piece, the bottom intercommunication of the jar body has the drain pipe.

Principle and effect of the technology: when the filter screen inside the tank body needs to be cleaned, the filter screen is only required to be taken down from the supporting rod, then a new filter screen is installed, and the operation is simple and convenient.

Further, the top welding of filter screen has the limiting plate, two it has with limiting plate complex recess to open on the bracing piece, the limiting plate joint is in the recess, the top welding of limiting plate has the connecting rod that is the L shape.

By adopting the scheme, a worker can take down the filter screen from the support rod only by the connecting rod on the support plate.

Further, the number of the filter screens is two, and the two filter screens are respectively arranged on two sides of the driving motor.

By adopting the scheme, the electroplating waste liquid in the tank body can be better filtered.

Further, guardrails are respectively arranged on two sides of the supporting plate.

By adopting the scheme, the working personnel can be protected, and the working personnel can be prevented from falling from the supporting plate.

Compared with the prior art, the utility model has the beneficial effects that: when the filter screen in the tank body needs to be replaced, the filter screen can be cleaned only by taking the limiting plate above the filter screen out of the groove on the supporting rod, and when a new filter screen needs to be installed, the filter screen can be fixed on the supporting rod only by clamping the limiting plate above the filter screen in the groove.

Drawings

FIG. 1 is a schematic diagram of a pretreatment apparatus for electroplating wastewater according to the present utility model;

in the figure: 1. a tank body; 2. a support rod; 3. a driving motor; 4. a liquid inlet pipe; 5. a liquid outlet pipe; 6. a stirring shaft; 7. a filter screen; 8. a limiting plate; 9. a connecting rod; 10. a ladder stand; 11. a support plate; 12. a guardrail.

Detailed Description

The following is a detailed description of the embodiments.

Examples: as shown in fig. 1, the electroplating wastewater pretreatment device comprises a tank body 1, wherein four support columns arranged at intervals are welded at the bottom of the tank body 1. The side wall of the tank body 1 is communicated with a liquid inlet pipe 4, the liquid inlet pipe 4 is used for injecting electroplating wastewater to be treated into the tank body 1, the bottom of the tank body 1 is communicated with a liquid outlet pipe 5, and the liquid outlet pipe 5 is used for discharging the treated electroplating wastewater. The inside top bolted connection of jar body 1 has two bracing pieces 2 that set up side by side, and the intermediate bolt connection of two bracing pieces 2 has driving motor 3, fixedly connected with is located jar inside (mixing) shaft 6 of body 1 on driving motor 3's the output shaft. Grooves are respectively formed in the support rods 2 on two sides of the driving motor 3, limiting plates 8 are respectively clamped in the grooves, filter screens 7 are respectively welded at the bottoms of the limiting plates 8, and L-shaped connecting rods 9 are respectively welded at the tops of the limiting plates 8. The lateral wall of the tank body 1 is connected with a cat ladder 10 through bolts, a supporting plate 11 is arranged between the top of the cat ladder 10 and the supporting rod 2, and two sides of the supporting plate 11 are respectively connected with a guardrail 12 through bolts.

When the filter screen 7 in the tank body 1 needs to be cleaned, a worker only needs to walk to the supporting plate 11 above the tank body 1 through the ladder 10, then holds the connecting rod 9 and lifts upwards to take the limiting plate 8 out of the groove, and the filter screen 7 is taken out to clean the filter screen. When a new filter screen 7 needs to be installed, the filter screen 7 can be fixed between the two support rods 2 only by clamping the limiting plate 8 on the filter screen 7 in the groove, and the operation is simple and convenient.
