Description

Technical Field

[0001] The utility model relates to the technical field of galvanizing tanks, in particular to a circulating hot-dip galvanizing tank. Background Art

[0002] The galvanizing tank consists of a heating chamber and a galvanizing tank. The heating chamber is set above the lined galvanizing tank, and a heating plate is set on the bottom of the heating chamber. Hot-dip galvanizing tanks are usually divided into two categories in terms of the materials used, namely tanks built with refractory materials and tanks made of steel materials. In the galvanizing project, some iron impurities will remain in the galvanizing liquid after a period of use, and it needs to be filtered before use.

[0003] An existing circulating hot-dip galvanizing tank is usually provided with a filtering device to filter the residue inside the galvanizing solution so that the galvanizing solution can be recycled. However, after the filter screen filters the residue, the residue inside the filter screen needs to be cleaned. During the cleaning process, the circulation pump needs to be stopped, thereby pausing the circulation mode of the galvanizing solution inside the galvanizing tank. Only after the cleaning is completed can the circulation pump be turned on again to filter and recirculate the galvanizing solution. This process is not convenient for continuous circulation and filtration of the galvanizing solution inside the galvanizing tank, and may cause excessive accumulation of impurities inside the galvanizing tank, thereby affecting the galvanizing quality of the product. Therefore, a circulating hot-dip galvanizing tank is needed. Utility Model Content

[0004] The purpose of the utility model is to provide a circulating hot-dip galvanizing tank, which has the characteristics of being able to use two filter baskets alternately to continuously circulate and filter the galvanizing liquid inside the galvanizing tank, thereby avoiding excessive accumulation of impurities inside the galvanizing tank and improving the quality of the galvanized product.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a circulating hot-dip galvanizing tank, comprising a tank body, the left and right ends of the tank body are connected with drainage pipes, the other ends of the two drainage pipes are connected with a filter box, the upper ends of the two filter boxes are provided with a groove, the upper ends of the two grooves are provided with an arc-shaped groove, the rear ends of the two filter boxes are installed with a motor, the output end of the motor passes through the filter box and is fixedly connected to a rotating shaft abutting the arc-shaped groove, the other end of the rotating shaft is rotatably connected to the inner wall of the groove, the outer wall of the rotating shaft is fixedly connected to a filter basket located inside the filter box, the upper end of the filter basket is fixedly connected to a limit plate, and the outer wall of the filter box is provided with a collection box;

[0006] The front end of the filter box is connected to a circulating water pipe, the other end of the circulating water pipe is connected to the tank body, and a second water pump is installed on the outer wall of the circulating water pipe;

[0007] A first water pump is installed on the outer wall of the drainage pipe.

[0008] In order to facilitate the diversion of the galvanizing liquid flowing into the filter box through the drainage pipe to the inside of the filter basket, as a preferred circulating hot-dip galvanizing tank of the present invention, the limit block is arranged obliquely and abuts against the inner wall of the filter box.

[0009] In order to prevent impurities from falling into the filter box through the gap between the filter basket and the filter box, as a preferred circulating hot-dip galvanizing tank of the present invention, the front and rear ends of the filter basket are in contact with the inner wall of the filter box.

[0010] In order to prevent impurities in the filter basket from falling to the outside of the collection box, as a preferred circulating hot-dip galvanizing tank of the present invention, the width of the filter basket is smaller than the width of the collection box.

[0011] In order to facilitate limiting the rotation position of the filter basket, as a preferred circulating hot-dip galvanizing tank of the present invention, the upper end of the collection box is fixedly connected to a limiting plate.

[0012] For the convenience of operation, as a preferred circulating hot-dip galvanizing tank of the present invention, a controller is installed at the front end of the tank body.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] During use, the first water pump on the left side is activated. The first water pump directs the galvanizing liquid from the tank body through a drainage pipe to the interior of a connected filter box. After filtering the galvanizing liquid through the filter basket, the second water pump on the same side is activated to direct the filtered galvanizing liquid from the filter box through a circulating water pipe to the interior of the tank body. To clean impurities from the left filter basket, the first and second water pumps on the left side are first turned off, while the first and second water pumps on the right side are simultaneously activated, allowing the galvanizing liquid from the tank body to continuously circulate and filter. The motor on the left side is then activated to drive the connected shaft and filter basket to rotate 180 degrees, directing impurities from the filter basket into the collection box. To clean impurities from the right filter basket, the first and second water pumps on the right side are turned off, while the first and second water pumps on the left side are simultaneously activated, allowing both filter baskets to circulate.

[0015] In summary, the two filter baskets can be used alternately to continuously circulate and filter the galvanizing liquid inside the galvanizing tank, thereby avoiding excessive accumulation of impurities inside the galvanizing tank and improving the quality of the galvanized product.
