Description

Technical Field

[0001] This utility model belongs to the technical field of thickener equipment and relates to a multi-functional pipe connection device for thickener discharge. Background Technology

[0002] Thickeners, as crucial equipment for solid-liquid sedimentation separation, are widely used in various industries, especially in the nickel hydrometallurgical industry where they are indispensable. The thickener operation involves top-to-center deep feeding, with the clear liquid overflowing from the top and the solid-turbid liquid settling at the bottom and being scraped and collected by a scraper at the bottom cone for discharge. The entire process requires strict control of the material feed and discharge balance. Rapid feeding or a decrease in discharge speed can cause material sedimentation, increasing the pressure on the thickener scraper and potentially jamming it, leading to thickener damage and inability to start.

[0003] If the thickener malfunctions, the material inside needs to be emptied for repair. However, the thickener can only be emptied from the bottom outlet. Typically, the bottom of the thickener outlet is equipped with only one valve, with an elbow and short pipe installed at the other end of the valve, which is then connected to the material conveying equipment. To empty the thickener, the elbow and short pipe need to be removed, and a temporary pipe needs to be installed after the valve to release the material. If the material stops flowing, the temporary pipe needs to be removed and a flushing water pipe needs to be installed to flush the material. After flushing, the temporary venting pipe needs to be reconnected to release the material. The above maintenance process requires repeated disassembly and reassembly of the pipes, which not only increases the labor intensity for workers but also causes the scattered material to pollute the site environment each time it is disassembled and reassembled. Therefore, there is an urgent need to design a multi-functional pipe connection device for thickener discharge. Utility Model Content

[0004] The purpose of this utility model is to address the problems existing in the prior art by providing a multi-functional pipe connection device for thickener discharge, which solves the problems that existing thickeners cannot quickly switch between different operations and require repeated disassembly and reassembly of pipes for maintenance, resulting in high labor intensity and pollution of the site environment.

[0005] Therefore, the present invention adopts the following technical solution:

[0006] A multi-functional pipe connection device for discharging a thickener includes a pipe connection body disposed at the bottom of the thickener. The pipe connection body is vertically arranged, with its top connected to the thickener via a first manual ball valve, its bottom provided with a second manual ball valve, and a first branch pipe and a second branch pipe respectively provided on both sides. The first branch pipe and the second branch pipe are both horizontally arranged.

[0007] The first branch pipe has a third branch pipe at its top, and the two are vertically connected. The third branch pipe is equipped with a third manual ball valve, and the other end of the first branch pipe is equipped with a fourth manual ball valve, which is connected to the material conveying equipment through a discharge pipe. The second branch pipe is equipped with a fifth manual ball valve.

[0008] Furthermore, the diameter of the main pipe of the connecting pipe is larger than the diameter of the first branch pipe and the diameter of the second branch pipe, respectively.

[0009] Furthermore, the diameter of the third branch pipe is smaller than that of the first branch pipe.

[0010] Furthermore, the first manual ball valve is connected to the main body of the connecting pipe via a first flange, the fifth manual ball valve is connected to the second branch pipe via a second flange, the second manual ball valve is connected to the main body of the connecting pipe via a third flange, the third manual ball valve is connected to the third branch pipe via a fourth flange, and the fourth manual ball valve is connected to the first branch pipe via a fifth flange; specifically, the first flange, second flange, third flange, fourth flange, and fifth flange are all loose flanges.

[0011] Furthermore, the first branch pipe, the second branch pipe and the main body of the connecting pipe are connected by welding, and the first branch pipe and the third branch pipe are also connected by welding.

[0012] Furthermore, the main body of the connector is made of welded steel pipe or seamless steel pipe.

[0013] Furthermore, the main body of the connecting pipe, the first manual ball valve, the second manual ball valve, the third manual ball valve, the fourth manual ball valve, and the fifth manual ball valve are all made of stainless steel or steel lined with rubber or steel lined with PE.

[0014] The beneficial effects of this utility model are as follows:

[0015] This utility model, by setting a multi-functional connecting pipe device connected to the bottom discharge port of the thickener cone, can realize the rapid switching of the thickener's normal discharge, blockage backflushing, shutdown discharge, and shutdown backwashing operations. During maintenance, there is no need to repeatedly disassemble the thickener pipeline, ensuring that the slag and solution do not fall to the ground, thus achieving clean production.
