Abstract
The utility model discloses a liquid outlet corrosion preventing device of a leaching kettle and relates to the improvement of liquid outlet corrosion prevention of the leaching kettle. A titanium tube mounting hole is expanded in a kettle body which is already lined with glass fiber reinforced plastic lining bricks, a pup joint which is fabricated by using a titanium tube or a titanium plate is mounted in the hole of the outlet of the kettle body, a gap between the kettle body and the periphery of the titanium tube is filled with a furan resin daub, a channel between the kettle body and the connector of a pump case is filled with gravel, and the titanium tube is fixed by a steel plate which is also used for blocking the gravel. The liquid outlet corrosion preventing device of the leaching kettle is capable of preventing the corrosion of the titanium tube in the channel and increasing the service life of the titanium tube, and also is convenient for replacing and mounting the titanium tube; by replacing the titanium tube at the liquid outlet, the integrated corrosion prevention effect of the leaching kettle is guaranteed, and the service life of the leaching kettle is prolonged.
Description
Technical field
The utility model relates to the conversion unit that leaches thick nickel hydroxide production nickel sulfate solution, relates in particular to a kind of leaching kettle liquid outlet corrosion-resisting device.
Background technology
In leaching thick nickel hydroxide production nickel sulfate solution production process, need to constantly pass into steam and dilute sulphuric acid, mechanical stirring, making its neutralization is single nickel salt, in order to make production process complete rapidly.In thick nickel hydroxide and dilute sulphuric acid and time, kettle and liquid outlet thereof in the continuous etch of dilute sulphuric acid, and the steam constantly passing into has aggravated the corrosion of liquid outlet titanium pipe.Leaching kettle adopts concrete depositing kettle backsight glass reinforced plastic to serve as a contrast acidproof clinker tile again, and kettle possesses erosion resistance, wear resistance; Liquid outlet selects flange to connect titanium pipe conventionally, titanium pipe has strong erosion resistance, but due to leach thick nickel hydroxide produce be constantly pass into steam, sulfuric acid is realized leaching, the titanium pipe of liquid outlet is subject to the continuous etch of sulfuric acid and high temperature, and titanium pipe at high temperature its erosion resistance can reduce, will soon seepage, when finding to occur seepage, titanium pipe need to carry out REPAIR WELDING, but weld bond has just suffered after etch REPAIR WELDING again, so the titanium pipe of liquid outlet is used essential replacing after for some time.
Utility model content
The utility model leaches in thick nickel hydroxide production nickel sulfate solution production process in order to solve, and the titanium pipe of leaching kettle liquid outlet is subject to the continuous etch of sulfuric acid and high temperature, and the problem of the troubles such as maintenance, frequent replacing, provides a kind of leaching kettle liquid outlet corrosion-resisting device.
In order to address the above problem, the following technical scheme of employing of the present utility model:
A leaching kettle liquid outlet corrosion-resisting device, leaching kettle liquid outlet is set with a titanium pipe, and described leaching kettle liquid outlet is remaining gapped except described titanium pipe, in described gap, is filled with furan mastic; The other end of described titanium pipe leads to a pump hole, between described pump hole and described leaching kettle, is provided with a passage, and described titanium pipe is positioned at described passage.
Described leaching kettle liquid outlet is provided with a baffle plate outward.
The other end of described titanium pipe is fixed on described pump hole by steel plate.
In space in described passage except titanium pipe, be filled with sandstone.
The beneficial effects of the utility model:
The utility model leaching kettle fluid bore is greater than titanium pipe caliber, between the outer wall of the titanium pipe of leaching kettle liquid outlet and suit, leave gap, in gap, be filled with furan mastic, the outside of furan mastic is provided with baffle plate, simple in structure, easy for installation, be convenient to shutdown period of changing, reducing whole equipment; The other end of titanium pipe leads to a pump hole and is connected with pump, between pump hole and leaching kettle, there is a passage, titanium pipe is positioned at passage, in passage, be filled with sandstone, further prevent the corrosion of titanium pipe in passage, increase the service life, by changing the titanium pipe of liquid outlet, guarantee the preservative effect of leaching kettle integral body, extend its work-ing life.
Accompanying drawing explanation
Fig. 1. be the utility model structural representation;
Fig. 2. be the titanium pipe enlarged view between leaching kettle and pump hole body of wall.
Embodiment
A leaching kettle liquid outlet corrosion-resisting device, leaching kettle liquid outlet 2 socket one titanium pipes 3, leaching kettle liquid outlet 2 suit titanium pipes 3 are rear remaining gapped 4, in gap 4, are filled with furan mastic; Leaching kettle liquid outlet is fixed a baffle plate 5 outward; The other end of titanium pipe 3 leads to a pump hole 1.Between pump hole 1 and leaching kettle, have a passage 6, titanium pipe 3 is positioned at passage 6, and passage 6 is filled with sandstone in interior space remaining except titanium pipe 3.In titanium pipe 3 the other ends and pump hole 1, delivery side of pump is connected, and titanium pipe 3 part that penetrates pump hole is fixed on pump by steel plate 7 and cheats.
Leaching kettle kettle is formed by concrete depositing lining glass reinforced plastic lining brick, on the kettle that has served as a contrast glass reinforced plastic lining brick, punch, expand titanium pipe nose end installation region, strengthen titanium pipe cavity is installed, titanium pipe 3 is sleeved on to leaching kettle liquid outlet 2, pipe end exceeds inner wall of kettle 100mm left and right, determine behind position the interior filling furan mastic in gap 4 remaining between liquid outlet and titanium pipe 3 outer walls, and furan mastic is filled closely in case gap leakage makes this installation cavity for removing titanium pipe at any time, change titanium pipe.Between pump hole 1 and leaching kettle, have a passage 6, titanium pipe 3 is positioned at passage 6, from one end, pump hole to passage in titanium pipe closely fill sandstone around.Leaching kettle liquid outlet is provided with a baffle plate 5 outward, filled after sandstone, titanium pipe 3 exits by furan mastic or concrete fixed wall in sandstone, and adopt steel plate 7 that titanium pipe 3 is fixed on to pump to cheat on 1 body of wall, titanium pipe 3 is connected with delivery side of pump in pump hole 1.When steel plate is installed, because being movable part, steel plate is two semi-rings, and steel plate and steel plate junction adopt electric welding, chooses 6-8 some expansion bolt is installed to fix in steel plate outside.By changing liquid outlet titanium pipe 3, guarantee the preservative effect of leaching kettle integral body, extend its work-ing life.During replacing: the destructive fixation steel plate movable part of removing, expose the hole of filling sandstone, draw out sandstone, the furan mastic of filling while titanium pipe being installed from beaing in leaching kettle, or directly knock titanium pipe furan mastic around its loosening until disengaging is taken off.
