Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lime milk transportation, in particular to a lime milk dosing pipeline transportation device. Background Art
[0002] In general industrial waste liquid treatment, some acidic wastewater will be neutralized with lime milk, so as to achieve the purpose of reducing the acidity of wastewater treatment. The current lime milk delivery pipeline is composed of pumps, pipelines, automatic start-stop valves, and manual gate valves. The manual gate valve is in a half-open state, and the pipeline pressure is manually adjusted to ensure the appropriate amount of addition.
[0003] In addition, in the process of conveying lime milk, in some cases the valve will be closed briefly after the amount of lime milk conveyed is sufficient. When the valve is closed, the lime pump is in operation. Therefore, some lime pumps have the function of temporarily holding the pump to avoid damage. However, under long-term use, the lime pump will have its service life reduced due to frequent holding of the pump. In addition, after closing the conveying valve, the lime milk inside the pipeline will be in a static state, which is prone to solidification into calcium, thereby affecting the service life of the pipeline.

DETAILED DESCRIPTION
[0024] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0025] Example:
[0026] Reference Figure 1-Figure 5The utility model discloses a lime milk dosing pipeline conveying device, comprising a lime pump 1 and a conveying pipe 2, wherein the conveying pipe 2 is connected to the output end of the lime pump 1, and a hose valve 3 is connected to the end of the conveying pipe 2. The outer peripheral side of the end of the conveying pipe 2 is connected to a pressure regulating bin 4, and two supporting cavity tubes 5 are fixedly connected to the top of the pressure regulating bin 4, and a supporting rod 6 is slidably connected to the bottom of the supporting cavity tube 5, and a counterweight piston plate 7 is connected between the bottom ends of the two support rods 6, and the bottom side of the counterweight piston plate 7 is in contact with the bottom side of the pressure regulating bin 4 and is connected to the piston of the pressure regulating bin 4, and a transfer pipe 8 is connected between the outer peripheral side of the conveying pipe 2 and the bottom side of the pressure regulating bin 4.
[0027] In this embodiment, when the lime pump 1 is conveying lime milk, the lime milk is conveyed from the conveying pipe 2 to the pipeline to be conveyed through the hose valve 3. When the lime milk in the pipeline is conveyed and closed by the switch valve, if the flow rate of the lime milk is slow, the pressure in the inner pipeline can be adjusted by the set hose valve 3 to avoid the phenomenon of lime pump 1 being blocked by excessive pressure. If the conveying flow rate of the lime milk is fast and the hose valve 3 cannot directly adjust the pressure in the pipe, the pressure in the pipe increases and the lime milk will enter the pressure regulating bin 4 from the transfer pipe 8. At this time, the lime milk will push the counterweight piston plate 7 to move upward, thereby causing the lime milk to enter the pressure regulating bin 4, thereby reducing the pressure in the conveying pipe 2. At the same time, the lime milk will continue to flow, avoiding the lime milk from standing and causing calcium to form in the pipeline, thereby avoiding the lime pump 1 being blocked. When the switch valve is opened and the lime milk is conveyed normally, the lime milk will be slowly conveyed to the conveying pipe 2 by the gravity of the counterweight piston plate 7 in the pressure regulating bin 4, so that the lime milk can be used normally.
[0028] In a further preferred embodiment of the present invention, Figure 2-4 As shown, a through hole 9 is opened on the top side of the pressure regulating chamber 4, and a sliding rod 10 is slidably connected in the through hole 9. The bottom end of the sliding rod 10 extends to the top side of the counterweight piston plate 7 and is fixedly connected to the counterweight piston plate 7. A counterweight nut 11 is threadedly connected to the top of the sliding rod 10.
[0029] In this embodiment, in some cases, the pressure of lime milk during transportation is different. The through hole 9 provided can be used for the sliding of the slide rod 10, so that the counterweight piston rod can drive the slide rod 10 to slide. By threading the counterweight nut 11 on the slide rod 10, the weight of the slide rod 10 and the counterweight piston plate 7 is increased, so that the pressure of the lime milk pushing the counterweight piston plate 7 needs to be increased, so that it can be used in pipelines with different pressures.
[0030] In a further preferred embodiment of the present invention, Figure 2-4As shown, a spiral groove 12 is opened in the support cavity 5, the top end of the support rod 6 extends into the support cavity 5, a slider 13 is fixedly connected to the top outer peripheral side of the support rod 6, the slider 13 is slidably connected to the spiral groove 12, and the bottom end of the support rod 6 extends to the bottom of the counterweight piston plate 7 and is fixedly connected to a stirring blade 14.
[0031] In this embodiment, the spiral groove 12 is set to drive the support rod 6 to slide upward when the counterweight piston plate 7 moves upward, and then drive the slider 13 to move upward. When the slider 13 slides in the spiral groove 12, it drives the support rod 6 to rotate along the trajectory of the spiral groove 12, and then drives the stirring blade 14 to rotate, so that the lime milk in the regulating bin can be stirred by the stirring blade 14, so as to achieve the effect of preventing the lime milk from being calcified when it is left standing.
[0032] In a further preferred embodiment of the present invention, Figure 2-4 As shown, the bottom side of the counterweight piston plate 7 is provided with an avoidance groove 15 for avoiding the stirring blade 14, the support rod 6 is dynamically sealed with the counterweight piston plate 7 through a sealing ring, and the top side wall of the pressure regulating chamber 4 is provided with an exhaust hole 16 at the support cavity tube 5.
[0033] In this embodiment, the avoidance groove 15 is used to avoid the stirring blade 14, so as to prevent the stirring blade 14 from blocking the counterweight piston plate 7 from fitting with the bottom side of the regulating chamber, thereby causing the counterweight piston plate 7 to be unable to block the position connected to the transfer pipe, thereby affecting the pressure regulation work.
[0034] In a further preferred embodiment of the present invention, Figure 5 As shown, a rotating shaft 17 is disposed in the transfer pipe 8 , a driving blade 18 is connected to the outer peripheral side of the rotating shaft 17 , and a mixing blade 19 is connected to the bottom of the outer peripheral side of the rotating shaft 17 .
[0035] In this embodiment, the rotating shaft 17 can drive the driving blades 18 to rotate when the lime milk flows into the regulating bin, and then drive the mixing blades 19 to rotate, so that the mixing blades 19 stir the lime milk in the conveying pipe 2 to prevent the lime milk from calcifying when it is left standing.
[0036] In a further preferred embodiment of the present invention, Figure 5 As shown, a positioning rod 20 is rotatably connected to the outer peripheral side of the rotating shaft 17 , and both ends of the positioning rod 20 are fixedly connected to the inner wall of the transfer tube 8 .
[0037] In this embodiment, the positioning rod 20 is fixedly connected to the inner wall of the transfer pipe 8, and the positioning rod 20 is rotatably connected to the rotating shaft 17, so that the rotating shaft 17 can rotate on the positioning rod 20, thereby allowing the mixing blades 19 and the driving blades 18 to be supported and rotated by the flow of lime milk.
[0038] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
