Technical field
Crystal ingot evolution technical field is the utility model is related to, particularly a kind of spray being used for solar cell crystal ingot evolution
Sand mouth and the abrasive blast equipment using above-mentioned blast nozzle.
Background technology
At present in polycrystalline crystal ingot evolution technique, there are the shortcomings that the following aspects for polycrystalline cutting blast nozzle in industry：
1. traditional blast nozzle spraying range is too small, slurry coverage deficiency, slurry can not be substantially arrived at and covered more
Crystal ingot surface, often leads to cutting power and does not reach requirement, in turn result in steel wire line bow it is excessive, seriously affect polycrystalline crystal ingot and open
Square efficiency, even results in crystal ingot size and opens partially, cause crystal ingot to scrap, it does not ensure that the coverage of mortar；
2. traditional blast nozzle, which is connected with four spraying pipes, leads to four side of guide wheel, slurry forms yarn by this four pipelines
Curtain is invested on the steel wire of four side guide wheels to strengthen the band sand ability of steel wire, but in actual application, to reduce evolution cost,
The viscosity of slurry does not often reach the technological standards of evolution, even if this results in mortar arrival, steel wire can still be rotated with high speed
Depart from steel wire, due to band sand scarce capacity during cutting, great line can be caused to bend, so not only easily cause steel wire to break, separately
On the one hand, excessive line bow can cut the spraying pipe of four side of guide wheel, cause pipeline break；
As it can be seen that traditional blast nozzle due to design reasons, does not ensure that the mobility and covering power of slurry, while
Limit the flow of slurry.

To solve the above problems, the utility model provides a kind of blast nozzle, the blast nozzle includes：
Pallet, the pallet are equipped with multiple sand jet outlets, and the edge of the upper surface of the pallet is equipped with baffle, to prevent
The slurry stated in pallet is excessive；
The frustum of a cone, it is arranged on the top of the pallet, for being shunted to the slurry for flowing into the pallet, the frustum of a cone
Lower surface and the pallet upper surface between be equipped with spacing.
Preferably, multiple sand jet outlets are arranged in array on the pallet.
Preferably, each sand jet outlet is rounded.
Preferably, the frustum of a cone is fixed at the top of the pallet by pillar.
The utility model also provides a kind of abrasive blast equipment, and the abrasive blast equipment includes：A mixing bowl and above-mentioned blast nozzle, it is described
Pipeline is connected with a mixing bowl, the pipeline is located at the top of the frustum of a cone of the blast nozzle, and the frustum of a cone is used for will be by institute
The slurry for stating pipeline outflow is shunted.
Compared with prior art, the beneficial effects of the utility model are：Good mobility can be provided for slurry, together
When can improve the covering power of slurry, and can ensure the flow of slurry.

Embodiment
It is below in conjunction with the accompanying drawings and specific real to make those skilled in the art be better understood from the technical solution of the utility model
Mode is applied to elaborate to the utility model.
The utility model provides a kind of blast nozzle, refers to Fig. 1 and Fig. 2, and blast nozzle includes pallet 1 and the frustum of a cone 2, support
Disk 1 is equipped with multiple sand jet outlets 11, and the edge of the upper surface 13 of pallet 1 is equipped with baffle 12, to prevent outside the slurry in pallet 1
Overflow, and to the slurry to splash because impacting the frustum of a cone 2 is drained, this part size is flowed to the frustum of a cone 2
Lower part, makes the slurry on pallet 1 be evenly distributed.The frustum of a cone 2 is arranged on the top of pallet 1, and the slurry point of pallet 1 is entered for convection current
Stream, slurry are uniformly drained on pallet 1 along the side of the frustum of a cone 2, the slurry that will be splashed with reference to baffle 12 because impacting the frustum of a cone 2
Material is drained, and slurry is distributed on pallet 1 more uniform, has between the lower surface of the frustum of a cone 2 and the upper surface 13 of pallet 1
There is spacing, the region for enabling to be in 2 lower part of the frustum of a cone on pallet 1 sets sand jet outlet 11, and then makes the slurry on pallet 1 overall
It is uniformly distributed, and is uniformly flowed out slurry by multiple sand jet outlets 11 on pallet 1.Slurry is flowed out by sand jet outlet 11, such as
Shown in Fig. 2, arrow therein is the flow direction of slurry, finally, slurry is more uniformly distributed in the surface of polycrystalline ingot,
