Problems solved by technology

[0003] During the recycling process of pickling sludge, it generally needs to go through the initial water filtration step to filter out the excess water in the sludge; currently, common methods such as exposure to the sun, air drying, etc., these methods need to spread the sludge and consume a lot of time. It takes a lot of time to dry; at the same time, people use the plate and frame filter press to filter the pickling sludge. This operation has high efficiency and can quickly obtain products after removing most of the water. After the filter press is completed, due to the force of the filter press itself, the obtained product is easy to accumulate into blocks, which is inconvenient for transportation and the next industrial production. Compared with the product obtained by exposure and air drying, the product is larger in size and needs to The next step of production can only be carried out after crushing

Embodiment 1

[0016] Example 1: Such as figure 1 A kind of pickling sludge filter water tank shown, the water filter tank is a cylindrical tank body 1, the top of the tank body 1 is provided with a sludge feed port 2, and the bottom of the tank body 1 is provided with There is a drainage port 3, the side of the tank body 1 is provided with a discharge port 4, and the middle part of the tank body 1 is provided with a water filter layer 5, and the water filter layer 5 is an elastic water filter layer. net, the bottom of the water filter layer 5 is provided with a drainage plate 6 that moves up and down in the tank body, and the two ends of the drainage plate 6 are provided with connecting rods 9 that are fixedly connected to the height adjustment motor 10, and the drainage A plurality of triangular drainage blocks 7 are evenly distributed on the plate 6 , and a drainage hole 8 is provided on the drainage plate 6 between two adjacent drainage blocks 7 to communicate with the lower part of th...

Embodiment 2

[0017] Example 2: Such as figure 1 As shown, the top of the tank body 1 is provided with a rotating motor 12, and the rotating motor 12 is connected directly above the water filter layer 5 through the stirring paddle 13; , not only prevent the sludge from clogging the water filter layer 5, but also prevent the pickling sludge from accumulating into blocks under the drive of the stirring paddle 13, and facilitate the collection of small-volume products.

Embodiment 3

[0018] Example 3: Such as figure 1 As shown, the bottom of the tank body 1 is provided with a conical water-guiding outlet plate 11, and the drain outlet 3 is arranged at the bottom of the water-guiding outlet plate 11; The excess pickling waste water in the mud is exported to the filter tank tank body 1 to avoid more waste liquid in the filter tank, and the pickling waste water is transferred to the equipment of the waste water recovery process.

Abstract

The invention discloses a tank for filtering water of pickling sludge. The tank is a cylindrical tank body, and a water filtering layer is an elastic water filtering mesh and arranged in the middle of the tank body; guiding plates capable of moving up and down in the tank body are arranged below the water filtering layer, connecting bars are arranged at two ends of each of the guiding plate and fixedly connected to a height adjustment motor, a plurality of angular guiding blocks are uniformly distributed on the guiding plate, and the guiding plate between two adjacent guiding blocks is provided with a guiding hole for communication with the lower part of the tank body. The tank for filtering water of pickling sludge conveniently filters waste water at the upper and the lower parts in accumulated sludge through the movable angular guiding plates and the elastic water filtering mesh structure, and has higher water filtering efficiency; the obtained product which does not agglomerate is convenient for transportation and next production process, and therefore the working efficiency of recovering pickling sludge by an enterprise is greatly improved.

Description

technical field [0001] The invention relates to the field of recovery and reuse equipment for pickling sludge, in particular to a filter tank for removing excess water contained in the pickling sludge. Background technique [0002] Stainless steel pickling is to make the surface of the steel clean. Before the steel is processed, use sulfuric acid or hydrochloric acid, nitric acid, hydrofluoric acid, or a mixture of the above-mentioned acids to pickle and derust the steel while heating. Pickling sludge mainly comes from the cleaning wastewater and waste residue produced by washing the residual acid on the surface of steel. These wastewater and waste residues will eventually form pickling sludge during the transmission process. Pickling sludge contains a large amount of heavy metal elements, which cannot be directly discharged into the environment. Through the treatment of pickling sludge, the recovery and reuse of metal elements in it has become a problem that people need to ...
