Description

Technical Field

[0001] The utility model relates to the technical field of pressure leaching in hydrometallurgy, and particularly relates to a slag removal tool for filtration in hydrometallurgy. Background Art

[0002] In the slurry preparation process of the pressure leaching system in hydrometallurgy, raw materials, salt solutions and various system acids are mainly formulated into pulp that meets the technical conditions requirements of subsequent processes. Usually, various specifications of pulp filters are set after the solution outlet pipeline of the main equipment, the pulping tank, in the pulping process. The large insoluble substances on the surface of the screen in the filter need to be fished and cleaned by a slag removal tool to prevent the accumulation of large particles from blocking the screen and causing the solution in the pulp filter to overflow, affecting the balance of valuable metals in the system and clean and civilized production. At present, the slag removal tool used in our factory is an ordinary iron shovel purchased externally. When in use, it is severely corroded by acid and needs to be replaced after only a few uses. It not only pollutes the pulp but also increases the production and operation costs. Moreover, during the process of scooping and cleaning, workers will also scoop out valuable pulp, resulting in the loss of valuable metal ions. Therefore, it is necessary to design a slag removal tool. Content of the Utility Model

[0003] The purpose of the utility model is to provide a slag removal tool for filtration in hydrometallurgy, which solves the problems in the prior art that the production of the slag removal tool for the filter is difficult, the severe acid corrosion causes a large consumption of spare parts, the loss of valuable metal ions and the inconvenience of personnel operation.

[0004] The technical solution adopted by the utility model is as follows:

[0005] The utility model discloses a slag removal tool for filtration in hydrometallurgy, which is characterized in that: it includes a rod body, a handle, a threaded sleeve, a slag removal spoon, a rolled edge and filter holes. The rod body, the handle and the slag removal spoon are horizontally welded and connected in sequence; the rolled edge and the slag removal spoon are vertically welded and connected; the threaded sleeve is wrapped outside the handle; the filter holes are arranged inside the slag removal spoon.

[0006] Further, the threaded sleeve is made of polytetrafluoroethylene material, which has both corrosion resistance and lightness.

[0007] Further, a threaded sleeve is sleeved on the handle to enhance the friction between the hand and the tool during the operation of personnel.

[0008] Further, the front end of the slag removal spoon is upturned in an arc shape, with rolled edges welded on both the left and right sides, and filter holes are densely arranged at the bottom. The front end of the slag removal spoon is designed in an arc shape to enhance the local pressure and reduce the resistance between the tool and the filtered slag, making it more convenient to insert into the large-particle filtered slag.

[0009] Further, the diameter of the filter holes is Φ8 - 12mm, and they are distributed in a matrix of 18×23, increasing the surface utilization rate to more than 75%.

[0010] Furthermore, the curled edge is vertically welded to both sides of the slag discharging spoon, which can effectively prevent the filtered slag from spilling inside the slag discharging spoon and improve the slag discharging efficiency.

[0011] The utility model has the following beneficial effects:

[0012] The utility model selects lightweight and corrosion-resistant materials such as titanium clad plate and polytetrafluoroethylene, which can meet the technical requirements of maintaining good tensile strength and toughness during long-term use of the tool in a sulfuric acid system and an oxidizing atmosphere. By horizontally welding and connecting the rod body, the handle and the slag discharging spoon, the operability of personnel in the effective space is improved. The front end of the slag discharging spoon is designed with a radian to reduce the resistance between the tool and the filtered slag, and filter holes are arranged on its surface in a matrix distribution. While effectively improving the surface utilization rate, the valuable metal solution in the filtered slag can be recovered, avoiding loss with the slag. The curled edge is vertically welded to both sides of the slag discharging spoon, which can effectively prevent the filtered slag from spilling inside the slag discharging spoon, improve the slag discharging efficiency, and is conducive to preventing the screen from being blocked due to untimely cleaning of the filtered slag.
