Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment equipment, in particular to a complete set of heavy metal wastewater treatment devices. Background Technique

[0002] The treatment of heavy metal-containing wastewater is a process of purifying the wastewater so that the heavy metals contained in the wastewater meet the water quality requirements for discharging into a certain water body or being reused. In the process of treating heavy metal wastewater, filter meshes are often used. Since a large number of metal aggregates will be formed in the heavy metal wastewater during treatment, during long-term filtration operations, the metal aggregates will block the filter meshes, so they often need to be removed. Most of the existing heavy metal-containing wastewater treatment equipment does not have a metal aggregate collection structure, and the metal aggregates removed from the filter meshes all fall to the bottom of the filtration tank. After a period of time, the equipment is paused, and the filtration tank is opened for manual cleaning. This method is time-consuming and laborious, increases the manual workload, and pauses the equipment, affecting the wastewater treatment process and reducing the wastewater treatment efficiency.

[0003] The publication (announcement) number is CN214528417, which discloses a complete set of heavy metal wastewater treatment equipment, specifically related to the technical field of wastewater treatment equipment, including a filtration tank, an adsorption tank, and a precipitation tank. A filter mesh plate is arranged inside the filtration tank, a motor is fixedly arranged at the top end of the filtration tank, a movable block is arranged inside the filtration tank, a first threaded rod is arranged inside the filtration tank, a cleaning brush is fixedly arranged on one side of the movable block, a communication port is opened at the bottom end of the filtration tank, a first placement groove is opened on one side wall of the communication port, and a second placement groove is opened on the other side wall of the communication port. By setting a collection tank, the removed metal aggregates can be centrally collected, and by setting a movable baffle, the metal aggregates in the collection tank can be discharged without pausing the equipment, reducing the workload of workers, and the equipment can continuously treat wastewater with high treatment efficiency.

[0004] Although the above solution can discharge the metal aggregates, when the movable baffle is adjusted to discharge the metal aggregates, the untreated wastewater will also be discharged synchronously with the metal aggregates, affecting the wastewater treatment effect, and the cleaning of the filter plate also requires the cooperation of a threaded rod and a motor, with high operating costs. Therefore, we propose a complete set of heavy metal wastewater treatment devices. Summary of the Utility Model

The cleaning wire fixedly arranged on the top slope surface of the obliquely installed plate can reciprocally disturb and clean the filter holes to avoid the accumulation and blockage of small-sized metal condensates. The cleaning and anti-blocking structure of the device is simple and the operation cost is low. BRIEF DESCRIPTION OF THE DRAWINGS
