Description

Crust breaking tool for aluminum electrolysis cell

Technical Field

The utility model relates to the technical field of electrolytic aluminum production, in particular to an aluminum electrolysis cell crust breaking tool.

Background

In the electrolytic production of aluminium, it is necessary to continuously replenish the electrolytic cell with material, such as alumina, aluminium fluoride etc., since the cell surface is normally covered with a crust of solidified electrolyte, it is necessary to puncture the crust prior to charging and to fill the cell with material from the open holes.

At present, a cylinder is mainly used for opening a crust to form a hole, but electrolyte is adhered to the surface of the crust-breaking hammer in the crust-breaking hammer crust-breaking operation process, the crust-breaking hammer is solidified to form a sticky package after the electrolyte is solidified, the sticky package is continuously increased along with the increase of the striking times, the lifting of the crust-breaking hammer is blocked when the sticky package is too large, the cylinder is also easily damaged, if the crust-breaking hammer is blocked and soaked in high-temperature electrolyte for a long time, the service life of the hammer is greatly shortened, and the striking work of the crust-breaking hammer is influenced; the constructor usually needs to frequently clear the electrolyte which is already wrapped on the crust-breaking hammer, and the prior art worker commonly uses a hammer to break away the wrapped electrolyte, so that the labor intensity is increased, certain loss is caused to the crust-breaking hammer, and the service life of the crust-breaking hammer is reduced.

Disclosure of Invention

The utility model aims to provide an aluminum electrolysis cell crust breaking tool, which solves the problems that electrolyte is easy to adhere to form a sticky package during crust breaking operation of a crust breaking hammer, a constructor frequently knocks down the sticky package by the hammer, and the working strength of the constructor is increased.

In order to achieve the above purpose, the basic scheme provided by the utility model is as follows: the utility model provides an aluminium cell crust breaking instrument, includes fixing base, crust breaking hammer, contact casing and connecting element, the rigid coupling has the mount on the fixing base, the mount rigid coupling has the cylinder, the flexible end of cylinder runs through the mount and links together with the crust breaking hammer, the slotted hole has been seted up to the fixing base, the fixing base is connected with the riser, the connecting element includes the slider, set up flutedly on the riser, slider sliding connection is in the recess, the rigid coupling has the spring between the bottom of slider and fixing base, contact casing and slider detachable connection, contact casing is located under the crust breaking hammer.

The principle and the beneficial effects of the utility model are as follows: according to the utility model, the crust breaking hammer head is driven by the air cylinder to lift for repeated crust breaking operation, the contact shell is arranged below the crust breaking hammer head, when the crust breaking hammer head performs crust breaking operation, the contact shell is not in direct contact with the surface and the inside of the electrolytic tank, the crust breaking effect is not affected by the electrolyte adhered to the surface of the crust breaking hammer head, the sliding block connected with the contact shell is arranged in the groove, so that the contact shell moves up and down in the vertical direction, and when the crust breaking hammer head resets, the spring resets to drive the contact shell to reset in time, and the contact shell is not soaked in the electrolytic tank for a long time.

The second scheme is the optimization of the basic scheme, the contact shell is fixedly connected with a fixed plate, and the fixed plate is connected with the sliding block through bolts; the fixing plate and the contact shell are convenient to assemble and disassemble from the sliding block through bolts.

In a third aspect, this is preferable in the second aspect, and the spring is a tension spring.

Fourth, which is the preference of the third, wherein the contact shell has a hemispherical structure; the contact shell of the hemispherical structure is matched with the surface of the crust-breaking hammer.

Detailed Description

The utility model is described in further detail below by way of specific embodiments:

reference numerals in the drawings of the specification include: 1. a contact housing; 2. a fixing frame; 3. a fixing seat; 4. a cylinder; 5. crust breaking hammer head; 6. a slot hole; 7. a vertical plate; 8. a groove; 9. a slide block; 10. a fixing plate; 11. and (3) a spring.

As shown in fig. 1 to 2: the utility model provides an aluminium cell crust breaking instrument, including fixing base 3, crust breaking hammer 5, contact casing 1 and connecting element, fixedly connected with mount 2 on the fixing base 3, fixing base 3 is located the mount 2 under, fixedly connected with cylinder 4 on the mount 2, the flexible end of cylinder 4 runs through mount 2 and with crust breaking hammer 5 fixed connection, slotted hole 6 has been seted up on the fixing base 3, the welding of the bottom of fixing base 3 has riser 7, fluted 8 has been seted up on the riser 7, connecting element includes slider 9, slider 9 sliding connection is in recess 8, be equipped with spring 11 in the recess 8, spring 11 is the extension spring, the both ends of spring 11 weld respectively on the bottom of fixing base 3 and slider 9.

The contact shell 1 is located under the crust-breaking hammer 5, the contact shell 1 is of a hemispherical structure, the contact shell 1 is fixedly connected with a fixing plate 10, threaded holes are formed in the fixing plate 10 and the sliding block 9, and the fixing plate 10 is fixed on the sliding block 9 through bolts passing through the two threaded holes.
