Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline transportation, and in particular relates to an intermittent liquid pipeline buffer device. Background Art

[0002] As the filtering stage of the two-stage dehydration of concentrate, the high-energy filter press directly affects the moisture content of the concentrate product. During the backwashing process, due to the large impact force of the liquid, the liquid rushed into the pool splashes out of the pool. The huge impact is accompanied by noise and vibration, which has a great impact on the pipeline and the equipment on the pipeline. Utility Model Content

[0003] The utility model provides an intermittent liquid pipeline buffer device, which aims to buffer the liquid in the pipeline and reduce the impact force of the liquid on the pipeline.

[0004] To this end, the utility model adopts the following technical solutions:

[0005] A discontinuous liquid pipeline buffer device comprises a buffer box, wherein one end of the buffer box is provided with an ore inlet and the other end is provided with an ore outlet; a plurality of baffles arranged at intervals are arranged in the buffer box along the liquid flow direction, and adjacent baffles are arranged alternately up and down, and the height of the baffles is greater than half the height of the buffer box; the baffles comprise vertical baffles and inclined baffles, and the inclined baffles are welded to the back of the vertical baffles for supporting the vertical baffles.

[0006] Furthermore, an overflow port is provided on the buffer box at one side of the mine inlet, and an overflow pipe and a regulating valve are connected to the overflow port.

[0007] Furthermore, the positions of the ore inlet and the ore outlet are staggered up and down, the ore inlet is located at the upper part of the buffer box, and the ore outlet is located at the lower part of the buffer box.

[0008] The design principle of the utility model is as follows:

[0009] Ordinary steel plates are used to cut out the required rectangular buffer box surface steel plates and internal baffles, the bottom steel plates and the top steel plates of the buffer box. The baffles are welded in advance, and the axis plate is welded on the longitudinal center line of the bottom steel plate. The baffle is slightly higher than 1 / 2 of the height of the front and rear steel plates of the buffer box. The inclined baffle is welded at an angle of about 20-30° to the rear side of the axis plate. The inclined baffle can disperse the impact force generated by the liquid in the buffer box and increase the service life of the buffer box. Two identical baffles are installed at both ends of the top steel plate of the buffer box to keep the internal channel of the buffer box uniform.

[0010] The front and rear steel plates of the rectangular buffer box cut out the inlet and outlet of the pipeline. The inlet of the pipeline is more than half of the height of the rectangular buffer box, and the outlet is less than half of the height of the buffer box. One more buffering can be performed at the inlet, and the outlet can allow all the liquid on the right side of the bottom baffle to flow out.

[0011] A small pipe outlet is cut at the bottom of the steel plate corresponding to the inlet of the rectangular buffer box, and a regulating valve is connected. The regulating valve is in a normally open state. When the liquid flows and the impact force is large, the valve is closed. When the liquid stops flowing and the impact force is small, the valve opens to discharge the accumulated liquid in the buffer box.

[0012] The beneficial effects of the utility model are as follows: the utility model reduces the pressure of high-speed liquid impact, realizes intermittent liquid pipeline buffering, reduces noise and vibration, avoids the pipeline system and equipment from being subjected to excessive water flow impact and pressure, prevents liquid from entering the pool and splashing, improves the on-site working environment, and reduces the time consumption of cleaning work and the labor intensity of construction personnel.

[0016] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0017] like Figure 1 and 2 As shown, an intermittent liquid pipeline buffer device, the outer shell and the internal baffle of the buffer box 1 are cut and made of ordinary steel plates, and then welded; the steel plates on both sides of the top of the buffer box 1 are welded as shown in FIG. Figure 1 The vertical baffle 5 and the inclined baffle 4 shown have a baffle height exceeding the height of the buffer box 1 1 / 2. The reverse resistance generated by the vertical baffle 5 can greatly reduce the impact force of the liquid and slow down the flow rate. The inclined baffle 4 can reduce the interaction force on the vertical baffle 5, making the buffer device have a longer service life. The mine inlet 2 is opened above the height of the buffer box 1 1 / 2 to ensure that the baffle takes effect. The mine outlet 3 is opened below the height of the buffer box 1 1 / 2 as close to the bottom steel plate as possible, which is convenient for the intermittent liquid pipeline buffer device to overflow the accumulated liquid in the right area. The accumulated liquid overflow port 6 in the left area of ​​the buffer device is opened at the bottom of the steel plate, and a regulating valve 7 is installed. The valve is in a normally open state. The pressure automatically regulates the valve 7 to open and close. There is liquid flowing in the pipeline. After the regulating valve 7 is subjected to the pressure to reach the set value, the valve is closed to allow the liquid to pass through the buffer box 1. After no liquid passes through the pipeline, the regulating valve 7 is opened to allow the accumulated liquid inside the buffer device to overflow.

[0018] Working principle of the utility model: liquid enters the buffer box 1 through the inlet 2, and after being resisted by the first baffle, the liquid changes its direction of movement, reducing the kinetic energy of the liquid itself and slowing down its speed. After being blocked by the subsequent baffle, the kinetic energy of the liquid is greatly reduced, and the speed is slowed down before flowing out through the outlet 3. When there is no liquid flowing in the buffer device, the regulating valve 7 is in a normally open state. Once the liquid enters the device, the regulating valve 7 is subjected to a certain pressure to close the valve, so that the liquid flows out from the outlet 3. After the liquid in the pipeline stops flowing, the pressure of the regulating valve 7 at the overflow port 6 is reduced, and the valve is opened to allow the liquid in the buffer device to flow out, preventing impurities in the liquid from settling or freezing.
