Detailed Description

Example 1

The water-sand separated sand blasting nozzle comprises a dry sand blasting nozzle 1, wherein an interlayer sleeve nozzle 2 is sleeved outside the dry sand blasting nozzle 1 in a fixed mode, the interlayer sleeve nozzle 2 comprises an inner shell 3, an outer shell 4 is sleeved outside the inner shell 3, a water spraying cavity 5 is reserved between the inner shell 3 and the outer shell 4, and a water inlet connector connecting hole 6 is formed in the outer shell 4.

The top parts of the dry sand-blasting nozzle 1 and the interlayer sleeve nozzle 2 are connected with a variable angle head 7.

The inner shell 3 and the outer shell 4 are sealed by welding.

The inner shell 3 and the outer shell 4 are sealed by sealing rings.

The inner shell 3 and the outer shell 4 are sealed by screw threads.

The inner shell 3 and the outer shell 4 are sealed in a hard-to-hard precise matching mode.

The dry sand blasting nozzle 1 and the interlayer sleeve nozzle 2 are fixed by fastening screws.

The dry sand blasting nozzle 1 and the interlayer sleeve nozzle 2 are welded.

The dry sand blasting nozzle 1 is in threaded connection with the interlayer sleeve nozzle 2.

According to the principle and the explanation of the water-sand separation type sand blasting nozzle of the embodiment, the sand blasting efficiency of a traditional sand blasting machine is high but the pollution is large, the imported and improved domestic sand blasting machines have low efficiency which is less than 1/5, so that the water-sand separation type sand blasting nozzle is designed on the basis of the principle and the explanation, an interlayer sleeve nozzle is sleeved outside a traditional dry sand blasting nozzle 1, and the connection mode comprises 1 and a fastening screw for fixed connection; 2. connecting by screw thread; 3. the sealing rings are connected, so that the assembly and disassembly modes are very convenient; the structure of interlayer cover mouth adopts the inlayer casing, has cup jointed outer casing outside the inlayer casing again, and connection mode between them adopts: 1. welding; 2. hard-to-hard precision sealing; 3. the inner shell and the outer shell are connected through threads; 4. sealing by a sealing ring; the lower part of the outer shell is provided with a water inlet joint connecting hole which can be connected with an upper elbow, a ball valve, a water connecting head and a water source to work, and if the water pressure is insufficient, a booster pump or a household water pump can be adopted to work, so that the water pump is very convenient; the outer casing leaves out the water space between the inlayer casing, for the sandblast post of the rivers of ejaculating wrap the inside, can allocate interlayer sleeve mouth, allotment mode according to water capacity, water range and range size: 1. the chamfering angle of the water outlets of the inner shell and the outer shell is changed; 2. the variable angle heads are additionally arranged at the top parts of the dry sand-blasting nozzle and the interlayer sleeve nozzle, so that the requirement of sprayed water flow is met.
