Ceramic Composite cylinder
Technical field
This utility model relates to sand mill technical field, particularly relates to a kind of Ceramic Composite cylinder.
Background technology
The cylinder of existing sand mill includes inner bag and shell, is provided with cooling structure between inner bag and shell, due to pottery originally
Body has corrosion-resistant, without advantages such as harmful components, therefore, uses ceramic material to make inner bag, and ceramic liner has wearability
Good, be easily worked, can service life of effective extension device, the advantage such as reduction production cost, be widely used on grinder.
In the course of the work, raw material is ground in cylinder sand mill, and friction generates heat for material, meanwhile, material with
Collide between ceramic liner friction, and life-time service can make ceramic liner be easily generated crack, and the material in cylinder passes through crack
Will enter in cooling structure, along with coolant circulates, cause cooling structure to block;Coolant in cooling structure can also be led to
Cross crack to enter into inner barrel and mix with material, cause material to pollute, cause wastage of material.
Utility model content
Technical problem to be solved in the utility model is: dirty in order to overcome after in prior art, crack occurs in ceramic liner
Dye material and the deficiency of blocking cooling system, this utility model provides a kind of Ceramic Composite cylinder, uses outside ceramic liner
Adhere to interlayer protection set and on the one hand ensure that the rigidity of ceramic liner, add service life, on the other hand use metal sandwich
Protection set, isolates inner bag with outboard structure when crack occurs in inner bag, it is to avoid material pollution and the impact on cooling structure.
The technical scheme that this utility model solves its technical problem to be taken is: a kind of Ceramic Composite cylinder, including by
The interior cylinder inner bag set gradually to outward and cylinder shell, be provided with interlayer protection set outside described cylinder inner bag, described interlayer is protected
Cooling structure it is provided with between sheath and cylinder shell.Use interlayer protection set cylinder inner bag is protected, interlayer protection set with
Cylinder inner bag connects the intensity that can strengthen cylinder inner bag, reduces the probability of damage, it addition, when cylinder inner bag damages, folder
Layer protection set also has buffer action, is kept apart with cooling structure by cylinder inner bag, it is to avoid the pollution of material.
Further, in order to strengthen cylinder inner bag and the connectivity robustness of interlayer protection set, described cylinder inner bag and interlayer are protected
Sheath is bonding by glue layer.Owing to different material needs the different glue of coupling, water-fast, oil resistant, high temperature resistant and corrosion resistant should be chosen
The strong glue of erosion property is as binding agent, owing to the characteristic of metal material is to expand with heat and contract with cold, even and if the material of pottery runs into high temperature,
Its deformation coefficient is very little, so if cylinder inner bag and interlayer protection set are to use interference fit or select other to join
Close, interior fittings can be damaged on the contrary, use glue bonding, both can ensure that fastness, and also can select the preferable glue of heat conduction,
Cooling effect can be improved.
Concrete, the thickness range of described glue layer is 0.1mm-10.0mm.
Concrete, described cylinder inner bag is ceramic liner.
Concrete, described interlayer protection set is metal protection protector.
Concrete, described cylinder shell is metal shell.
Further, in order to realize the connection of cylinder and other structures, described cylinder shell two ends are additionally provided with adpting flange.
Concrete, described cooling structure includes spiral tank and is arranged on the water inlet on described cylinder shell and water outlet
Mouthful, described spiral tank two ends are connected with described water inlet and outlet respectively.Spiral cooling structure is used to extend cold
But the path that liquid flows through in spiral tank, improves cooling effect.
Further, in order to improve cooling effect, described spiral tank is two groups, charging aperture set successively to discharging opening direction
Put inside cylinder shell.
The beneficial effects of the utility model are: a kind of Ceramic Composite cylinder that this utility model provides, and use in pottery
Adhere to interlayer protection set outside gallbladder and on the one hand ensure that the rigidity of ceramic liner, add service life, on the other hand use gold
Belong to interlayer protection set, when crack occurs in inner bag, inner bag is isolated with outboard structure, it is to avoid material pollutes and to cooling structure
Impact.

Detailed description of the invention
Presently in connection with accompanying drawing, this utility model is described in detail.This figure is the schematic diagram simplified, the most in a schematic way
Basic structure of the present utility model is described, therefore it only shows the composition relevant with this utility model.
As it is shown in figure 1, a kind of Ceramic Composite cylinder of the present utility model, including the cylinder inner bag set gradually from inside to outside
1, interlayer protection set 2 and cylinder shell 3, cylinder inner bag 1 is ceramic liner, and interlayer protection set 2 and cylinder shell 3 are metal material
Making, cylinder inner bag 1 is bonding by glue layer with interlayer protection set 2, and the thickness range of glue layer is 0.1mm-10.0mm, interlayer
Being provided with cooling structure between protection set 2 and cylinder shell 3, cooling structure includes spiral tank 4 and is arranged on cylinder shell 3
Water inlet 5 and outlet 6, spiral tank 4 two ends are connected with water inlet 5 and outlet 6 respectively, and spiral tank 4 is two groups, by
It is internal that charging aperture 7 is successively set on cylinder shell 3 to discharging opening 8 direction, and two groups of spiral tank 4 pitch and spiral quantity are homogeneous
With, but the hand of spiral is identical or contrary, and often group is for half cylinder of cooling.Cylinder shell 3 two ends are additionally provided with adpting flange 9,
Flange 9 is welded to connect with cylinder shell 3, it is simple to connect fixing.Cylinder inner bag 1 can be one section or multistage, but does not at most surpass
Cross 15 sections, the cooling structure between cylinder inner bag 1 and cylinder shell 3 and the quantity Matching of cylinder inner bag 1.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant work
Personnel can carry out various change and amendment completely in the range of without departing from this utility model.This utility model
Technical scope is not limited to the content in description, it is necessary to determine its technical scope according to right.
