Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pulp discharge, in particular to a device for eliminating the impact force of pulp. Background Technique
[0002] During ore discharging, the pulp directly discharges from the secondary underflow pipe along the dam top to the dam foot, with relatively large potential energy, which is likely to cause the phenomenon of scouring the dam body. For safety reasons, most engineering parties adopt the method of laying anti-seepage membranes at the pipe orifice to reduce the impact force.
[0003] However, the use of anti-seepage membranes has high costs and is easily pressed down by the anti-seepage membranes (ore sand presses down the membrane). If the anti-seepage membrane is not installed flatly, the phenomenon of scouring the dam body will still occur, which requires wasting a lot of manpower and material resources to adjust the position of the anti-seepage membrane, and it cannot be recycled and reused, which is very inconvenient.
[0004] Now, a new device for eliminating the impact force of pulp is proposed to solve the above problems. Content of the Utility Model
[0005] The purpose of the utility model is to provide a device for eliminating the impact force of pulp to solve the problem of frequent replacement of the permeable membrane proposed in the above background technique.
[0006] To achieve the above purpose, the utility model provides the following technical scheme: a device for eliminating the impact force of pulp, including a welding frame and side rod A. At the front and rear ends of the center of the top of the welding frame, side rod A is welded respectively. At the front and rear ends of the right side of the top of the welding frame, side rod B is welded respectively. A hydrocyclone is bridged between side rod A and side rod B, and an energy dissipation barrel is fixed between the bottom of the hydrocyclone and the welding frame. A feed pipe is welded at the upper right corner of the hydrocyclone. A first flange is arranged on the right side of the outside of the hydrocyclone. A second flange is arranged on the right side of the center of the hydrocyclone. A third flange is arranged at the middle position of the hydrocyclone. A fourth flange is arranged on the left side of the center of the hydrocyclone. A fifth flange is arranged on the left side of the hydrocyclone.
[0007] Preferably, a support plate is hinged at the center between one ends of side rod A, and a fastening bolt is meshed and connected in the hole at the center of the outside of side rod A.
[0008] Preferably, a reinforcing rod is welded at the top of side rod B, and an assembly block is fixed on the side surface of the reinforcing rod. A positioning bolt is meshed and connected in the assembly block. A cross beam is welded between the front and rear of the center of side rod B.
[0009] Preferably, screw holes are respectively arranged at the centers of the front and rear ends of the second flange, and the positioning bolt passes through the screw holes.
[0010] Preferably, a feed chute is arranged at the upper right of the energy dissipation bucket, the left side of the cyclone is embedded in the feed chute, three underflow ports are arranged at the lower left of the energy dissipation bucket, and a discharge pipe is welded in the underflow ports.
[0011] Preferably, the position of the discharge pipe is lower than that of the cyclone, and the discharge pipe has a certain inclination.
[0012] Preferably, three through grooves are welded at the lower part of the left side inside the energy dissipation bucket, and a plug plate is longitudinally inserted in the through grooves. Lap joints are respectively welded at the front and rear ends of the top of the plug plate.
[0013] Preferably, the radian of the plug plate is the same as that of the inner wall of the through groove, and the plug plate can vertically enter and exit the through groove.
[0014] Compared with the prior art, the beneficial effects of the utility model are as follows: The device for eliminating the impact force of pulp not only realizes the long-term reduction of the impact of pulp, maintains the stability of the cyclone, but also realizes the multi-notch discharge of pulp;

It has the ability of rotary centrifugation inside, can screen large and small particles and export them from different pipelines. The surface of the cyclone is distributed with the first flange, the second flange, the third flange, the fourth flange and the fifth flange for assembly.

Only need to vertically lift the plug plate with the lap joint along the inner wall of the through groove, and the through groove can be used to guide the flow of the pulp or change the feeding direction.

A fifth flange 14 is arranged on the left side of the hydrocyclone 5;
[0025] A support plate 3 is hinged at the center between one ends of the side lever A2, a fastening bolt 4 is meshed and connected in a hole at the center outside the side lever A2, a reinforcing rod 7 is welded to the top of the side lever B6, an assembly block 22 is fixed to the side surface of the reinforcing rod 7, a positioning bolt 21 is meshed and connected in the assembly block 22, a cross beam 8 is welded between the front and back at the center of the side lever B6, screw holes 20 are respectively arranged at the centers of the front and back ends of the second flange 11, and the positioning bolt 21 passes through the screw hole 20;
[0026] Specifically, as Figure 1 、 Figure 2 and Figure 3 shown, the hydrocyclone 5 is in an inclined state above the welding frame 1. This object has the ability of rotational centrifugation inside, can screen large and small particles and export them through different pipelines, and the surface of the hydrocyclone 5 is distributed with the first flange 9, the second flange 11, the third flange 12, the fourth flange 13 and the fifth flange 14 for assembly. The sunken end is reinforced by the adjustable support plate 3 controlled by the fastening bolt 4, and the upward end is assisted and connected by the assembly blocks 22 at the front and back positions. After aligning the screw hole 20 with the assembly block 22, the positioning bolt 21 is rotated and locked, which can ensure that the pulp in the hydrocyclone 5 passes through the feed trough 15 and accurately falls into the energy dissipation barrel 16;
[0027] Embodiment 2: A feed trough 15 is arranged at the upper right of the energy dissipation barrel 16, the left side of the hydrocyclone 5 is embedded in the feed trough 15, three underflow ports 17 are arranged at the lower left of the energy dissipation barrel 16, and a discharge pipe 18 is welded in the underflow port 17.

[0028] Specifically, as Figure 1 and Figure 2 shown, the overall steel plate thickness of the energy dissipation barrel 16 is about 6 - 12 mm. At this time, the lower left corner of the hydrocyclone 5 is embedded in the feed trough 15 by about 15 cm.

The overall steel plate thickness of the energy dissipation barrel 16 is about 6-12 mm. At this time, the lower left corner of the cyclone 5 is embedded into the feeding groove 15 about 15 cm. The pulp flowing out of the cyclone 5 will first impact the steel barrel wall, and then flow downwards, and enter the discharge pipe 18 through the three underflow ports 17. A flange can also be installed on the outside of this discharge pipe 18 to connect to other places for material transportation. One, two or all of them can be selected according to the weight and speed of the pulp transported by the cyclone 5.
