[0002] For the environmental protection treatment of rust removal, paint removal or deburring on the surface of objects such as ship decks, hardware workpieces, etc., it can be used for high-pressure water sandblasting. The existing operation method is water and sand pressurized by a water pump. After being directly mixed, it is sprayed out through a thicker pipeline. On the one hand, the water pressure is often insufficient, and the sandblasting effect is not good. On the other hand, the water consumption is large and the waste is serious. Fine treatment of the surface of the object needs to be improved

Embodiment Construction
[0023] see figure 1 - Image 6 , providing a new type of high-pressure sandy water jet nozzle assembly, including a pipe joint 1, the rear of the pipe joint 1 is connected with a high-pressure water inlet pipe, and the high-pressure sandy water jet nozzle assembly also includes a cap nut 2 and a nozzle from front to back 3. The main body 4 and the current collector block 5. An annular groove 7 is provided inside the head cover 6 of the cap nut 2 . The nozzle 3 can be made of tungsten steel, which has high hardness and can withstand the scour of the high-pressure water-sand mixed flow. The injection port 10 connected to the nozzle seat 8, the surface of the nozzle head 9 is provided with a V-shaped groove 11, the injection port 10 is oval, and is located in the middle of the bottom of the groove, so that the high-pressure water-sand mixed flow ejected from the injection port 10 can be fan-shaped shape, the area of action on the surface of the object is larger. In practical...

The invention discloses a novel high-pressure sandy water jet nozzle assembly which comprises a pipe joint and further comprises a cap nut, a nozzle, a main pipe and a flow collection core pellet. A pipe cover is arranged at a front pipe orifice of the main pipe, an external threaded pipe communicated with the main pipe is connected on the pipe cover, a sinking groove is formed in the middle of an inner chamber of the main pipe, a cavity is formed between the sinking groove and the pipe cover in the inner chamber, a sand inlet communicated with the cavity is formed in the wall of the main pipe, and the external threaded pipe is in threaded connection with the cap nut; the flow collection pellet is inserted into the sinking groove and communicated with the cavity, a small hole is formed in each of the front side and the rear side of the flow collection pellet, a diversion core resistant to high temperature and having a flow collection hole is embedded between the small holes on the front and rear sides in the flow collection pellet, hole diameter of the flow collection hole is smaller than that of the small holes on the front and rear sides of the flow collection pellet, and the flow collection hole is communicated with the small holes; the front portion of the pipe joint is in threaded connection with the rear portion of the main pipe. Due to the above structure, higher water pressure can be formed, effect of sand blasting of the surface of an object is better, water consumption is low, water is saved remarkably, and the novel high-pressure sandy water jet nozzle assembly is suitable for performing fine treatment on the surface of the object.
Description
technical field [0001] The invention relates to the technical field of sand blasting treatment on the surface of objects, in particular to a novel high-pressure sand-laden water jet nozzle assembly. Background technique [0002] For the environmental protection treatment of rust removal, paint removal or deburring on the surface of objects such as ship decks, hardware workpieces, etc., it can be used for high-pressure water sandblasting. The existing operation method is water and sand pressurized by a water pump. After being directly mixed, it is sprayed out through a thicker pipeline. On the one hand, the water pressure is often insufficient, and the sandblasting effect is not good. On the other hand, the water consumption is large and the waste is serious. Fine processing of the surface of the object needs to be improved. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a new type of high-pressure sand-laden wa...
