Description

Slurry sand feeding device of thickener

Technical Field

The utility model relates to a mine tailing concentrates and fills technical field, more specifically says, relates to a thickener tailings slurry sand feeding device.

Background

The tail sand conveying pipeline of the thickener is used for conveying tail sand slurry into the thickener, 2 or even 3 pipelines are usually used, and the problem that how the tail sand conveying pipeline of the thickener is connected with a thickener interface is solved. However, the workbin needs to have the buffer storage capacity of at least 2-3min, so the workbin must be large enough, the height of the workbin is usually high, the feed opening of the workbin is flush with the feed opening of the thickener, a special supporting structure and an overhauling platform are needed, or a supporting platform b with the height of more than 10 meters needs to be built, and the two methods cause construction difficulty and large investment. In addition, the tailing conveying slurry has fast flow speed and great scouring to the structure of the material box, so that the material box is easy to wear and damage.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a sand device is advanced to thickener ground paste that the construction is easy, the investment is little, long service life.

The utility model provides a sand device is advanced to thickener ground paste includes the tailings pipeline, still includes the pressure release subassembly, and this subassembly includes pressure release cavity and crooked pipe, and this crooked pipe one end stretch out the pressure release cavity and communicate with the tailings pipeline, the other end in the pressure release cavity and unload the ground paste extremely in the pressure release cavity, there is a discharge gate bottom this pressure release cavity, and this discharge gate communicates to its transport ground paste with the thickener.

In a preferred embodiment, the pressure relief cavity is a spherical cavity. The curved conduit is arranged on the upper half part of the spherical cavity.

In order to facilitate replacement of the pressure relief assembly, the pressure relief cavity is detachably connected with the tailing conveying pipeline and the thickener. The elbow is detachably connected with the pressure relief cavity through a flange valve.

Preferably, the diameter of the spherical cavity is not less than 3 times of the diameter of the tailing conveying pipeline.

In order to monitor the slurry feeding flow and judge the slurry conveying condition, an electric valve gate and a pressure gauge are arranged on the tailing conveying pipeline.

Preferably, the discharge port is communicated with the thickener through a bent pipe.

The utility model discloses owing to set up the pressure release subassembly, make the ground paste can the pressure release buffering carry, can turn into the laminar flow by the turbulent flow from the flow state of selecting the mill to the tailings ground paste of thickener. Furthermore, the utility model discloses simple structure, the easy low cost of preparation no longer needs great buffering workbin or 10 meters high supporting platform, and the installation is easy, the maintenance of being convenient for.

Reference numerals:

the device comprises a tailing conveying pipeline 1, a pressure relief assembly 2, a pressure relief cavity 21, a pressure relief bent conduit 22, a pressure relief buffer area 23, a discharge hole 24, an elbow pipe 3, a flange valve 4, an electric switching gate valve 5 and a pressure gauge 6.

Detailed Description

From fig. 1 can see the utility model discloses thickener ground paste advances sand device still has two tailings pipeline 1, still has a pressure release subassembly 2, and this subassembly includes pressure release cavity 22 and crooked pipe 22, and

pressure release cavity

21 and 1 intercommunication with tailings pipeline are stretched out to this crooked pipe 22's one end, and crooked pipe 22's the other end is in pressure release cavity 21 and unload the ground paste to in the pressure release cavity 21, be ground paste pressure release buffer 23 below crooked pipe 22 in the pressure release cavity, the ground paste in the crooked pipe 22 will get into this pressure release buffer 23, has a discharge gate 24 in pressure release cavity bottom, and this discharge gate is through a return bend 3 and thickener I intercommunication. The pressure relief cavity 21 is made of a wear resistant ceramic or other wear resistant material to withstand slurry impact.

It can be seen from fig. 2 that the pressure relief cavity 2 is a spherical cavity in this embodiment, although it is not excluded that other shapes of cavity are used, the diameter of the spherical cavity is at least three times of the diameter of the tailings conveying pipeline 1, a slurry pressure relief buffer zone 23 is arranged in the spherical cavity, and slurry discharged from the bent conduit 22 is properly released in the pressure relief buffer zone 23 and then enters the thickener I through the bent pipe 3.

The bent conduit 22 should be connected to the tailing conveying pipeline 1 through the flange valve 4, and the discharge port 24 of the pressure relief assembly 2 should also be connected to the elbow 3 through the flange valve, so as to facilitate the detachment or replacement of the pressure relief assembly 2.

The tailing conveying pipelines 1 can be connected with an electric switching gate valve 5 and a pressure gauge 6, whether the switching of the two tailing conveying pipelines 1 is correct or not and whether accidents such as pipe blockage occur or not are judged in advance through monitoring of the pressure gauge 6 in the tailing conveying process, and a relatively stable pressure is required during normal conveying. The two tailing conveying pipelines are switched only by switching the electric switching gate valve 5 in the control room, the displayed value of the pressure gauge 6 is transmitted to the computer control room through the pressure sensor, and the pressure value can be displayed on the computer to judge whether the tailing conveying is normal or not.

When the pressure relief cavity 21 is installed, the discharge port 24 at the bottom of the pressure relief cavity is connected with the elbow 3 by adopting a large-radius elbow, so that material accumulation is avoided.

The utility model discloses during the preparation, should make the pressure release subassembly earlier so that reserve at any time, pass through flange valve 4 with this subassembly and two tailings conveying pipeline 1 of top and return bend 3 of below during the use and be connected to convenient dismantlement or change.
