the utility model belongs to the technical field of chemical industry mineral processing equipment and specifically relates to a hydraulic classifier is with water jet equipment.

Background art:

the hydraulic classifier is widely used in the field of chemical ore dressing and is equipment for classifying and screening sand materials according to particle sizes by utilizing the principle of interference sedimentation. However, most existing hydraulic classifiers adopt bottom water supply, water is supplied (sprayed) upwards through a turbulent plate (a small hole is formed in the plate or a one-way nozzle is arranged), sand still enters the nozzle in all use processes, even the sand is blocked, the water supply uniformity is affected, and the classification effect is further affected.

The utility model has the following contents:

the utility model provides a water spraying device for hydraulic classifier, which aims to overcome the defects in the prior art.

The application provides the following technical scheme:

the utility model provides a water jet equipment for hydraulic classifier, it includes the casing of hydraulic classifier, is equipped with the bin outlet bottom the casing, is equipped with overflow mouth, its characterized in that on casing upper portion: the shell is provided with a group of horizontally distributed spray pipes in a penetrating way, each spray pipe positioned on the inner side of the shell is provided with a group of spray holes distributed along the axial direction of the spray pipe, the spray holes spray water downwards, the end parts of the two ends of the spray pipes positioned on the outer side of the shell are communicated with a water collecting tank, and the two ends of the water collecting tank are respectively provided with a water inlet.

On the basis of the technical scheme, the following further technical scheme can be provided:

and connecting plates correspondingly matched with the shell are sleeved at the two ends of the water spray pipe.

Two sections of thick wall parts are symmetrically arranged on the shell, and a pair of connecting through holes correspondingly matched with the spray pipes are arranged on the thick wall parts.

The connecting through hole on one side of the shell is internally provided with a ring groove which is coaxially distributed, and the ring groove is internally provided with a packing sealing box which is correspondingly matched with the spray pipe.

Utility model advantage:

the utility model discloses simple structure, convenient to use, the sand material divides classification effect good, and the hole for water spraying can not blockked up by the sand material, and the water spray is even, advantages such as whole dismouting easy maintenance. Particularly, one end of the spray pipe is flexibly connected through the packing sealing box, so that the problems of deformation, machining errors and the like of the spray pipe can be compensated.

Description of the drawings:

fig. 1 is a schematic structural diagram of the present invention;

FIG. 2 is an enlarged view of the line A in FIG. 1;

fig. 3 is a schematic top view of the present invention.

The specific implementation mode is as follows:

as shown in figures 1-3, the water spraying device for the hydraulic classifier comprises a shell 1 of the hydraulic classifier, a discharge port 2 is arranged at the bottom of the shell 1, and an overflow port 3 is arranged at one side of the upper part of the shell 1. The wall of the shell 1 at two sides of the middle part is respectively provided with a section of thick wall part 1a which is symmetrically distributed. A group of horizontally distributed connecting through holes 1b are arranged on the thick-walled parts 1a on the two sides. A water spraying pipe 4 is arranged on the two connecting through holes 1b which are coaxially distributed on the left side and the right side in a penetrating way, and a group of water spraying holes 4a which are distributed along the axial direction of the water spraying pipe 4 are arranged on the lower part of the pipe body of the water spraying pipe 4 in the shell 1, so that the water spraying holes 4a spray water vertically downwards.

The two ends of the spray pipe 4 are sleeved with round connecting plates 4b, and a group of screws 4c connected and fixed with the thick-wall part 1a penetrate through the connecting plates 4 b. The connecting through hole 1b on the right side of the shell 1 is internally provided with a ring groove 1c which is coaxially distributed, and a packing sealing box 1d which is correspondingly matched with a pipe body of the spray pipe 4 in the connecting through hole 1b is filled in the ring groove 1 c. An annular flanging 4d which is in press fit with the sealing box 1d through the insertion ring groove 1c is arranged on the connecting plate 4b on the same side.

The end parts of the two ends of the spray pipe 4 positioned outside the shell 1 are communicated with a water collecting tank 5, the water collecting tank 5 comprises an upper wall 5a and a lower wall 5b which are distributed and welded on the outer walls of the upper side and the lower side of the thick-wall part 1a, and a groove-shaped structure is formed by the upper wall 5a, the lower wall 5b and the outer wall of the thick-wall part 1 a.

The end parts of the upper wall 5a and the lower wall 5b extend out of extension parts a which are vertically distributed, and the upper extension part a and the lower extension part a are symmetrically distributed. An outer shell 5c with a semicircular section is arranged, and the upper end and the lower end of the outer shell 5c are respectively provided with an extension part b which is distributed corresponding to the extension part a. The upper and

lower walls

5a and 5b and the outer case 5c are connected together by inserting a connection screw c between the extension portion a and the extension portion b. The two ends of the upper wall 5a, the lower wall 5b and the outer shell 5c in the length direction are provided with sealing structures, the two ends of the sealing structures are provided with water inlets 5a, and the end part of the water inlet 5d is provided with a flange 5e which is connected and matched with a water pipe.

The working principle is as follows:

water is sprayed into the shell of the hydraulic classifier through a water spraying hole 4a below the water spraying pipe 4 and flows downwards, and then is turned upwards to the overflow port 1 to be discharged; in the sand material evenly added hydraulic classifier through feeding device, when running into the water of turning up, because the interference of receiving water subsides the effect, certain granule size's sand material gets into overflow mouth 1 along with the rivers come-up and discharges, other receive the little large granule sand material of interference settlement effect, the overflow that floats is not enough to make it upward movement, then can subside to the bin outlet 2 discharge of hydraulic classifier bottom to reach the purpose of classifying the sand material. And the water spraying holes spray water downwards, so that the blockage of the water spraying holes is greatly reduced. And 5 length direction both ends of header tank are equipped with the mode of water inlet 5d respectively for it is more even to intake, thereby has guaranteed the even water spray volume of each hole for water spraying.
