Wherein, the end of the shell 23 is provided with threads for connecting a water spray joint. The housing 23 is connected to an external connection element, such as a nipple of a spray head or a threaded bore of a water line, by means of an end-mounted screw.

Specifically, the elastic telescopic assembly 28 includes a telescopic connecting member 281 and a telescopic protecting sleeve 283, both ends of which are respectively connected with the guide cone 29 and the positioning bracket 25, and the telescopic protecting sleeve 283 is sleeved outside the telescopic connecting member 281. The telescopic protection sleeve 283 is used for preventing the telescopic connector 281 from being corroded in water flow, so as to improve the service life of the telescopic connector 281.

Preferably, in this embodiment, the telescopic connector 281 and the telescopic protection sleeve 283 are both springs. The spring has the pretightning force, through pretightning force pulling direction cone 29, when adding water pressure and changing, the shower nozzle can automatically regulated direction cone 29 with interval between the delivery port 26 stabilizes the shower nozzle striking atomizing watering effect, forms stable spouting flow.

Of course, in other embodiments, the elastic telescopic assembly 28 may be elastic rubber bands, and both ends of the rubber bands simultaneously pull the guide cone 29 and the positioning bracket 25. The water flow channel 21 is Y-shaped, the positioning bracket 25 divides the water flow channel 21 into a water inlet cavity 211 and a water outlet cavity 212, along the water flow direction, the cavity in the water inlet direction is the water inlet cavity 211, the cavity in the water outlet direction is the water outlet cavity 212, and the outlet at the end part close to the cavity of the water outlet cavity 212 is the water outlet 26.

Specifically, the positioning bracket 25 is provided with a positioning hole 251 and a water passing hole 253 penetrating through the upper and lower surfaces thereof, the end of the guide shaft 27, which is far away from one end of the guide cone 29, is limited in the positioning hole 251, and water flows from the water passing hole 253, i.e. water flowing into the water inlet cavity 211 flows from the water passing hole 253 to the water outlet cavity 212.

The included angle between the conical surface of the guide cone 29 and the central axis is an atomization angle alpha, and the value range of the atomization angle alpha is more than 0 and less than 90 degrees. It can be understood that spray heads with different atomization angles alpha can be selected according to different water pressure levels of the added water and different installation positions in the mixer, so that proper atomization effects under different requirements are realized.

It will be appreciated that the spray coverage is large because the exterior of the pilot cone 29 is tapered so that the water flow forms an impinging atomized spray pattern as it exits the gap between the pilot cone 29 and the water outlet 26. In the prior art, the cylindrical water is concentrated and the coverage area is small because the space of the cylinder body of the mixer is larger, and the problem that the cylindrical water spraying mode cannot be adopted to spray the material surface exists; meanwhile, columnar water flows out from the fixed orifice, the water flow atomization effect is poor, the two poles of the granularity of the mixture in the mixer are seriously differentiated, the sintering speed is reduced due to the increase of the proportion of small granularity, the production energy consumption is increased, and the sintering return ore is increased due to the increase of the proportion of large granularity, so that the yield of finished products is reduced.

Further, the guiding cone 29 has the function of reducing the water yield and the pressure of the water flow when the water outlet 26 is blocked by the impurity and the foreign matter, the guiding cone 29 can retract under the elastic telescopic assembly 28 to impact the impurity and the foreign matter of the water outlet 26, and the repeated retraction impact can loosen the impurity and the foreign matter to be discharged, so that the automatic dredging of the online production is realized, the shutdown maintenance times are reduced, and the labor is saved. When no water is sprayed, the water outlet 26 can be closed, so that dust or mixture deposition in the mixer is prevented from blocking the spray head. The outlets of the existing process spray heads are fixed tapered pipe orifices and are only subjected to single-side water flow pressure, and when the added water contains impurities, the pipe orifices are blocked, and the pipe orifices need to be manually overhauled and dredged.

As another preferred embodiment, the spray head further includes a limiting bracket 30 and a shaft protecting sleeve 31, the limiting bracket 30 is disposed in the accommodating space 21 and is fixed on the inner wall of the housing 23, the limiting bracket 30 is disposed at an interval with the positioning bracket 25, two ends of the shaft protecting sleeve 31 are detachably connected with the positioning bracket 25 and the limiting bracket 30 respectively, and the guide shaft 27 and the shaft protecting sleeve 31 both pass through the limiting bracket 30. The shaft protecting sleeve 31 may support the limiting bracket 30 and the positioning bracket 25, and may also protect the guide shaft 27.

The working process of the spray head is as follows: under the condition of no water spraying, the guide shaft 27 axially retracts under the action of the resilience force of the elastic telescopic assembly 28, and at the moment, the guide cone 29 closes the water outlet 26 to prevent dust and impurities in the mixer from entering the deposition blocking spray head. Under the water spraying working condition, the added water enters the water inlet cavity 211 first, enters the water outlet cavity 212 through the water passing holes reserved by the positioning support 25, then reaches the water outlet 26 through the water passing holes 253 of the limiting support 30, pushes the guide cone 29 to move axially under the action of water pressure, opens the water outlet 26, and after flowing out of the water outlet 26, the water flows into the guide cone 29 to form atomized water flow to spray out, the telescopic connecting piece 281 and the telescopic protective sleeve 283 freely stretch out and draw back according to the water pressure, and the distance between the guide cone 29 and the water outlet 26 is automatically adjusted according to the spring stretching amount caused by the water pressure change so as to realize a good atomization effect, thereby meeting the requirements of the water content change of the mixed material and the added water quantity and the uniform wetting effect when the water pressure of the added water changes. After the water spraying working condition is finished: the water flow pressure becomes smaller, the guide cone 29 slowly contracts under the water flow flushing, and finally the water outlet 26 is closed, so that the phenomenon that the water outlet 26 is blocked by adhesion and deposition of dust and impurities of the mixer to influence the next normal water spraying is avoided. When the water quality impurity particles of the added water block the water outlet 26, the outflow pressure of the water flow is reduced, the guide cone 29 is contracted under the action of the traction force of the elastic telescopic assembly 28, the end part of the guide cone 29 can impact the impurities of the water outlet 26, and the impurities are loosened and discharged due to repeated impact.

The utility model also provides a mixer, wherein the spray head is arranged in the mixer and used for spraying the mixture in the mixer, and the mixture is stirred into particles in the process of spraying.
