Description
Technical field
The present invention relates to cement industry manufacturing technology field, more particularly to a kind of shower nozzle.
Background technology
In recent years, the mixing material species used in the development equipped with cement grinding process, cement is more and more, cement
And the fineness of cement mixing material is also more and more thinner.At present, sieve formula (GB/T is generally used with mixing material to cement and cement
1345) its fineness is detected.Sieve formula mainly has negative pressure sieve formula and water sieve method.Sieve formula can be more than sieve with reaction mass
The content of bore portion particle.
The materials such as lime stone, cement after levigate because the viscosity reason such as big, powered easily produces reunion, according to negative pressure
Sieve formula, which is determined when tailing over, easily occurs paste sieve phenomenon, influences result of the test.Therefore generally using water sieve method to lime stone, cement etc.
The fineness of material is detected.Water sieve method is to rinse material with the current of certain pressure, makes material by screen cloth, is determining stone
During the viscous materials such as lime stone more can accurate response material tail over.
Existing standard GB/T 1345-2005《Cement fineness method of inspection sieve formula》In be to the regulation of water sieve method by
Experiment water sieve is placed on the water sieve seat with rotary shaft, with the shower nozzle of unified specification, under regulation hydraulic pressure, adjustment current and screen cloth
Height and angle, promote experiment water sieve by certain speed rotation, the fine grained in sieve is rushed by screen cloth at the appointed time
Walk, so as to reach the purpose of screening.
As shown in figure 1, shower nozzle of the prior art includes nozzle 101 and flexible pipe 102, nozzle 101 has inner chamber, nozzle
101 inner chamber one end open, the inner chamber of nozzle 101 includes tapered wall (not indicated in figure) and the bottom surface being connected with tapered wall
(not indicated in figure), internal diameter of the nozzle 101 at tapered wall is in the trend gradually increased, nozzle by the direction of opening to bottom surface
101 are provided with the fluid hole (not indicated in figure) of insertion on the bottom surface of inner chamber.Nozzle 101 is in one end of the opening of inner chamber with passing through
Flexible pipe 102 is connected with outer water tube, so that the inner chamber of nozzle 101 is connected with the inner chamber of outer water tube.
During stating technical scheme in realization, inventor has found that at least there are the following problems in the prior art：Flexible pipe
102 internal diameter is smaller than the internal diameter of outer water tube, after nozzle 101 is connected by flexible pipe 102 with outer water tube, is come out from water pipe
Current again can be gradually thicker after the inner chamber of nozzle 101 is flowed through via that can attenuate after flexible pipe 102, then, finally just from nozzle 101
On fluid hole outflow.In this whole process, because flexible pipe 102 and the internal diameter of the inner chamber of nozzle 101 are changing always, cause
The pressure of current is also all the time in change, and then cause the test result of experiment inaccurate, or even larger error occurs.
Further, since flexible pipe 102 is not fixed, easily shaken by after external force, cause the angle and height of shower nozzle frequent
It can change, so as to further increase the error of experiment.
