Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a wastewater recovery and treatment device for hot-dip galvanizing production. Background Art

[0002] Hot-dip galvanizing, also known as hot-dip galvanizing, is an efficient metal corrosion protection method and is widely used in metal structural facilities in various industries. The principle is to immerse the rust-free steel parts in zinc liquid melted at about 500°C to adhere a zinc layer to the surface of the steel components, thereby achieving the purpose of corrosion protection. This method has the advantages of dense coating, no organic inclusions, and strong covering ability. It can significantly extend the service life of steel. Hot-dip galvanizing not only has a mature process, but is also environmentally friendly and energy-saving. Wastewater containing heavy metals will be produced during the hot-dip galvanizing process, which is generally treated through wastewater recovery and treatment equipment to avoid damage to natural resources and biodiversity.

[0003] The existing Chinese patent with announcement number CN209872547U discloses a hot-dip galvanizing wastewater treatment device for wear-resistant and corrosion-resistant metal products, including a shell, a cover plate waste slag trough, a drain outlet, a water inlet, a baffle and a slag discharge outlet. The bottom of the cover plate is clamped with the top of the shell, the left end of the waste slag trough is fixedly connected to the right end of the shell, the right end of the drain outlet is fixedly connected to the left end of the shell, the left end of the water inlet is fixedly connected to the right end of the shell, and the slag discharge outlet is opened at the left end of the shell.

[0004] Although the above scheme prevents the metal in the wastewater from corroding the shell, the device only filters through multiple filter layers, and the water treatment effect of heavy metal ions in hot-dip galvanizing wastewater is not sufficient. At the same time, as the filtration process proceeds, the filter layer will gradually be blocked by suspended matter and impurities in the wastewater and needs to be cleaned. In addition, the cleaning of the device is inconvenient, resulting in a decrease in filtration efficiency. Therefore, it does not meet the existing needs. In this regard, we propose a wastewater recovery and treatment device for hot-dip galvanizing production. Utility Model Content

[0005] The utility model aims to provide a wastewater recovery and treatment device for hot-dip galvanizing production, so as to solve the problems that the wastewater recovery and treatment device proposed in the above background technology has insufficient treatment effect on hot-dip galvanizing wastewater and is easy to clog the filter layer and affect the filtration efficiency.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a wastewater recovery and treatment device for hot-dip galvanizing production, comprising a main body, a water inlet chamber is opened on one side of the upper end of the main body, a reaction chamber is opened on the other side of the main body, and the reaction chamber is connected to the water inlet chamber;

[0007] It also includes a mounting groove, which is opened on one side of the water inlet cavity, and three equally spaced limit clamps are arranged inside the mounting groove, and filter plates are arranged at the lower ends of the limit clamps, and one end of the filter plates extends into the water inlet cavity, and the filter plates are slidably matched with the water inlet cavity;

[0008] It also includes a transmission chamber, which is opened above the reaction chamber, and stirring shafts are rotatably arranged on both sides of the lower end of the reaction chamber, and one end of the stirring shafts penetrates and extends to the inside of the transmission chamber, and a liquid adding pipe is arranged on one side of the upper end of the reaction chamber, and one end of the liquid adding pipe extends to the outside of the main body;

[0009] It also includes a disinfection cavity, which starts at one side of the lower end of the main body. A liquid outlet pipe is arranged on one side of the disinfection cavity, and one end of the liquid outlet pipe extends to the outside of the disinfection cavity.

[0010] Preferably, a motor is provided on one side of the upper end of the transmission chamber, and the output end of the motor is connected to one of the stirring shafts via a coupling.

[0011] Preferably, the outer wall of the stirring shaft at one end inside the transmission cavity is provided with a transmission gear, and the transmission gears are meshedly connected with each other.

[0012] Preferably, the outer wall of the stirring shaft at one end inside the reaction chamber is welded with three groups of stirring blades distributed evenly, and each group of stirring blades is welded with four stirring blades distributed evenly in a ring shape.

[0013] Preferably, a reverse osmosis purifier is provided on one side of the reaction chamber, and the reverse osmosis purifier is communicated with the reaction chamber, an activated carbon filter is provided above the reverse osmosis purifier, and the activated carbon filter is communicated with the disinfection chamber, and a water pump is provided on one side of the activated carbon filter, and the water pump is connected to the reverse osmosis purifier and the activated carbon filter.

[0015] Preferably, a dust cover is rotatably mounted on the upper end of the main body, and the dust cover is located above the mounting groove.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The utility model opens an installation cavity on one side of the upper end of the main body. When the filter plate needs to be replaced after long-term use, the operator only needs to open the dust cover and lift the limit card plate upward to take the filter plate out from the inside of the water inlet cavity. By providing three filter plates, when a single filter plate is cleaned, the remaining two filter plates can filter normally, thereby avoiding affecting the treatment of sewage. The cleaning operation is simple and convenient, and it is easy to use.

[0018] 2. The utility model opens a reaction chamber on one side of the main body. When the hot-dip galvanizing wastewater enters the reaction chamber, the medicine liquid can enter the reaction chamber through the liquid adding pipe, and the motor is started at the same time. The start of the motor will realize the synchronous rotation of the two stirring shafts, and the stirring shafts will drive the stirring blades to rotate synchronously to generate a stirring vortex. The double vortex not only covers every corner of the reaction chamber, but also promotes the mixing of different density and flow rate areas in the wastewater, so that the medicine liquid can be dispersed into the wastewater more quickly and evenly, avoiding the phenomenon of local excessively high or low concentrations, ensuring sufficient mixing of the wastewater and the medicine liquid, and thus improving the treatment effect of the hot-dip galvanizing wastewater.

[0019] 3. The utility model opens a disinfection chamber on one side of the lower end of the main body. When the hot-dip galvanizing wastewater reacts with the liquid medicine, the water pump is started to make it enter the reverse osmosis purifier. The reverse osmosis purifier separates the soluble solids, organic matter, heavy metal ions and other harmful substances from the water molecules in the wastewater through high pressure. Then the wastewater enters the activated carbon filter, which can adsorb a large amount of pollutants such as organic matter and heavy metal ions, effectively remove organic matter, chromaticity, odor and other pollutants in the wastewater, and improve the water quality of the wastewater. When the wastewater enters the disinfection chamber, the ozone generator is started to let ozone pass into the wastewater, which can quickly react with the organic matter and microorganisms in the wastewater, destroy their cell structure, and achieve the purpose of disinfection, thereby realizing sufficient purification of the wastewater.
