A kind of boiler hot well anti-corrosion sacrificial anode device of embodiment
Present embodiment discloses a kind of boiler hot well anti-corrosion sacrificial anode devices, as shown in Figure 1, including casing 4, fixed
Part 3 and sacrificial anode 2.Wherein, casing 4 is fixedly welded on the side side wall of boiler hot well 1, and casing 4 by boiler hot
The outside of well 1 horizontally extends into its inside, and sacrificial anode 2 is located at the inside of boiler hot well 1, and fixing piece 3 is located at boiler hot-water
The outside of well 1, fixing piece 3 and sacrificial anode 2 are protruded into casing 4 by the both ends of casing 4 along the axial direction of casing 4 respectively, and are sacrificed
Anode 2 and one end close to each other of fixing piece 3 are mutually connected together, and the installation of sacrificial anode 2 has been achieved.
The material that the present embodiment sacrificial anode 2 is selected is magnesium, aluminium or zinc etc., and preferred material is magnesium.Its specific structure is such as
Shown in Fig. 2, sacrificial anode 2 is club shaped structure, is formed on the end face that sacrificial anode 2 protrudes into 4 one end of casing along sacrificial anode 2
The slot 201 that is recessed inwardly of axis, in sacrificial anode 2 and be located at slot 201 and protrude into the end of sacrificial anode 2 and be formed with
Card slot 202, and card slot 202 is connected with slot 201.
As in Figure 3-5, fixing piece 3 has the inserted link 301 that can be protruded into slot 201, and inserted link 301 and 201 phase of slot
Adaptation.Two clamping pieces 303 are welded in one end that inserted link 301 and sacrificial anode 2 are mutually inserted, two clamping pieces 303 are along slotting
The axisymmetrical of bar 301 is arranged, and is clamped piece 303 with elasticity.When in the insertion slot 201 of the inserted link 301 and end of inserted link 301
When in card slot 202, two clamping pieces 303 are elastically engaged in card slot 202.The present embodiment is in order to improve casing 4 and fixed
The leakproofness of part 3, inserted link 301 are removably connected with seal cap far from one end of sacrificial anode 2, and seal cap is for covering casing 4
The end in outside, threaded hole 307 is provided in seal cap, and inserted link 301 is threadedly coupled by threaded hole 307 with seal cap.This implementation
Example, in the dismounting of inserted link 301, is formed with operating groove on one end end face of the seal cap far from described sleeve pipe 4 for the ease of seal cap
306, operating groove 306 protruding into and fixing for allen wrench.The present embodiment seals to further reinforce sealing effect
It is formed with embedded groove 304 on the surface that cap and casing 4 fit, is embedded with sealing ring 305 in embedded groove 304.
Inserted link 301 relatively rotates the present embodiment with casing 4 in order to prevent, separate in casing 4 as shown in Fig. 6, Fig. 8
One end of sacrificial anode 2 is formed there are two limiting slot 401, each limiting slot 401 by casing 4 outside end along casing 4 axis
Line extends internally.In one end end setting of the inserted link 301 far from clamping piece 303, there are two limited block 302, two limited blocks
302 correspond with two limiting slots 401 respectively, and limited block 302 is adapted with corresponding limiting slot 401.
The present embodiment is in order to be strapped in sacrificial anode 2 tightly in casing 4, to improve the stability of sacrificial anode 2, such as
Shown in Fig. 7, multiple elastic slices 402 are equably provided with along the circumferential direction of casing 4 in one end that casing 4 protrudes into boiler hot well 1, these
The connection type that elastic slice 402 is all made of welding is fixed on the end of 4 inside of casing.When sacrificial anode 2 protrudes into casing 4, these
Elastic deformation and apical grafting occur for elastic slice 402 on the surface of sacrificial anode 2.The present embodiment is in order to make elastic slice 402 and sacrificial anode 2

Lock sleeve 403 is set at portion, lock sleeve 403 is threadedly coupled with casing 4.When lock sleeve 403 under external force turn along casing 4
Axis is moved to elastic slice 402, and lock sleeve 403 oppresses elastic slice 402, so that elastic slice 402 is adjacent to sacrificial anode 2, elastic slice has been achieved
402 tighten on the surface of sacrificial anode 2.
The installation and removal process of the utility model embodiment sacrificial anode 2 is as follows:
The installation process of sacrificial anode 2, firstly, the water level of boiler hot well 1 is drained into the bottom of casing 4 hereinafter, again
Sacrificial anode 2 and inserted link 301 are protruded into the both ends of casing 4, and ensure that the clamping piece 303 of 301 end of inserted link is connected to sacrifice sun
In the card slot 202 of pole 2, simultaneously limited block 302 is inserted into corresponding limiting slot 401；Later, rotary locking cover 403,
So that lock sleeve 403 is moved along the axis of casing 4 to elastic slice 402, and when lock sleeve 403 offsets with elastic slice 402, lock sleeve 403
Elastic slice 402 is oppressed, and then braces elastic slice 402 in the peripheral surface of sacrificial anode 2；Then, seal cap is spun on inserted link 301
End, and allen wrench rotatory sealing cap is used, until seal cap is tightly bonded in the end face of casing 4.
The disassembly process of sacrificial anode 2 and the operating procedure of its installation process are on the contrary, this will not be repeated here.
Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this
