Screw conveying equipment and waste liquid treatment system

Abstract

The present application discloses a screw conveying device and a waste liquid treatment system, which relate to the field of screw conveying technology. The screw conveying device is placed at an angle so that the first end of the first shell is higher than the second end. The solid-liquid mixed fluid flows into the interior of the first shell from the input port. The rotating shaft rotates to convey the solid-liquid mixed fluid from the second end of the first shell to the first end of the first shell. The solid-liquid mixed fluid can flow from the liquid output port to the deflection component. The deflection component is used to allow the liquid in the solid-liquid mixed fluid to flow out of the deflection component and block solid particles. The spiral blade near the solid output port is provided with a plurality of first through holes. When the liquid approaches the solid output port, the liquid flows through the first through holes under the action of gravity toward the second end of the first shell. The liquid cannot be transferred to the solid output port, and the solid particles cannot pass through the first through holes, so they can be discharged from the solid output port, thereby achieving solid-liquid separation.

Description

Technical Field

[0001] The present application relates to the field of screw conveying technology, and in particular to a screw conveying device and a waste liquid treatment system. Background Art

[0002] A screw conveyor is a machine that uses a motor to drive the screw to rotate and push materials to achieve the purpose of conveying. It can convey horizontally, inclined, or vertically, and has the advantages of simple structure, small cross-sectional area, good sealing, easy operation and maintenance, and convenient closed transportation.

[0003] In related technologies, screw conveying equipment is used to transport crystals obtained from high-salt waste liquid when used to treat high-salt waste liquid. However, the crystals are usually mixed with residual waste liquid. The screw conveying equipment can only play a conveying role and cannot achieve solid-liquid separation during the conveying process. Summary of the Invention

[0004] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application proposes a screw conveying device and a waste liquid treatment system that can achieve solid-liquid separation.

[0005] According to the first embodiment of the present application, the spiral conveying device includes:

[0006] a first shell, wherein a solid output port is provided at a first end of the first shell, an input port is provided at a second end of the first shell, and the first shell is further provided with a liquid output port, the liquid output port being located between the solid output port and the input port, and the input port being used to input a solid-liquid mixed fluid;

[0007] a rotating shaft rotatably mounted within the first housing, the rotating shaft being provided with a spiral blade, the spiral blade being spirally arranged along the axis of the rotating shaft, the spiral blade being provided with a plurality of first through holes near the solid output port, and the diameter of the first through holes being smaller than the diameter of the solid particles of the solid-liquid mixed fluid;

[0008] a first driving member, the first driving member being connected to the rotating shaft and configured to drive the rotating shaft to rotate;

[0009] A deflection assembly is installed at the liquid outlet, and is used to allow the liquid in the solid-liquid mixed fluid to flow out of the deflection assembly and to block the solid particles so that the solid particles flow back into the first shell.

[0010] According to the spiral conveying device of the embodiment of the present application, there are at least the following beneficial effects: when using the spiral conveying device of the embodiment of the present application, the spiral conveying device is placed at an angle so that the first end of the first shell is higher than the second end, the solid-liquid mixed fluid includes solid particles and liquid, and the solid-liquid mixed fluid flows into the interior of the first shell from the input port, and the first driving member drives the rotating shaft to rotate. The rotating shaft and the spiral blades can convey the solid-liquid mixed fluid from the second end of the first shell to the first end of the first shell. In this process, since the liquid output port is located between the solid output port and the input port, the solid-liquid mixed fluid can flow from the liquid output port to the deflection assembly. The deflection assembly is used to allow the liquid in the solid-liquid mixed fluid to flow out of the deflection assembly and to block the solid particles in the solid-liquid mixed fluid from flowing out of the deflection assembly. The solid particles flow back to the interior of the first shell under the action of gravity.

In this way, while completing the transportation of the solid-liquid mixed fluid, the solid-liquid separation of the solid-liquid mixed fluid is also achieved.

[0051] Reference Figures 1 to 7The first embodiment of the present application provides a spiral conveying device, comprising:

[0052] A first shell 100 is provided with a solid output port 110 at a first end of the first shell 100, an input port 120 at a second end of the first shell 100, and a liquid output port 130 located between the solid output port 110 and the input port 120. The input port 120 is used to input a solid-liquid mixed fluid;

[0053] The rotating shaft 200 is rotatably mounted within the first housing 100 and is provided with a spiral blade 210 . The spiral blade 210 is spirally arranged along the axis of the rotating shaft 200 . The spiral blade 210 near the solid output port 110 is provided with a plurality of first through holes 211 . The diameter of the first through holes 211 is smaller than the diameter of the solid particles in the solid-liquid mixture.

[0054] A first driving member 300, the first driving member 300 is connected to the rotating shaft 200, and the first driving member 300 is used to drive the rotating shaft 200 to rotate;

[0055] The deflector assembly 400 is installed at the liquid outlet 130 . The deflector assembly 400 is used to allow the liquid in the solid-liquid mixed fluid to flow out from the deflector assembly 400 and to block the solid particles in the solid-liquid mixed fluid so that the solid particles flow back into the first shell 100 .

[0056] The spiral conveying device according to the embodiment of the present application has at least the following beneficial effects: the first end and the second end of the first shell 100 implemented in the present application are opposite to each other. When using the spiral conveying device of the embodiment of the present application, the spiral conveying device is placed at an angle so that the first end of the first shell 100 is higher than the second end. The solid-liquid mixed fluid includes solid particles and liquid. The solid-liquid mixed fluid flows into the interior of the first shell 100 from the input port 120. The first driving member 300 drives the rotating shaft 200 to rotate. The rotating shaft 200 and the spiral blade 210 can convey the solid-liquid mixed fluid from the second end of the first shell 100 to the first end of the first shell 100. In this process, since the liquid output port 130 is located between the solid output port 110 and the input port 120, the solid-liquid mixed fluid can flow from the liquid output port 130 to the deflection component 400. The deflection component 400 is used to allow the liquid in the solid-liquid mixed fluid to flow out of the deflection component 400 and to block the solid particles in the solid-liquid mixed fluid from flowing out of the deflection component 400. The solid particles cannot flow out of the deflection component 400, and the solid particles flow back to the interior of the first shell 100 under the action of gravity. And because the spiral blade 210 near the solid output port 110 is provided with a plurality of first through holes 211, when the liquid approaches the solid output port 110, under the action of gravity, the liquid flows through the first through holes 211 to the second end of the first shell 100, and the liquid cannot be transmitted to the solid output port 110, and the solid particles cannot pass through the first through holes 211, and are thus output from the solid-liquid output port 110. In this way, while completing the transportation of the solid-liquid mixed fluid, the solid-liquid separation of the solid-liquid mixed fluid is also achieved.

[0057] It should be noted that the spiral blade 210 on the rotating shaft 200 can be integrally formed and located between the solid outlet 110 and the liquid outlet 130 , and the spiral blade 210 close to the solid outlet 110 is provided with a first through hole 211 .

[0058] It is worth noting that since the liquid output port 130 is located between the solid output port 110 and the input port 120, the solid-liquid mixed fluid can flow from the liquid output port 130 to the deflection component 400. The deflection component 400 is used to allow the liquid in the solid-liquid mixed fluid to flow out of the deflection component 400 and to block the solid particles in the solid-liquid mixed fluid from flowing out of the deflection component 400. The solid particles cannot flow out of the deflection component 400. At this time, the deflection component 400 completes the preliminary solid-liquid separation, but some liquid still remains in the solid-liquid mixed fluid. When the solid-liquid mixed fluid is transported to a place near the solid output port 110, under the action of gravity, the liquid can easily flow through the first through hole 211 to the second end of the first shell 100, while the solid particles are difficult to pass through the first through hole 211. Therefore, the liquid cannot be transmitted to the solid output port 110, but the solid can be transmitted to the solid output port 110, thereby further completing the solid-liquid separation.

[0059] It should be noted that the solid-liquid mixed fluid includes solid particles and liquid. For example, the solid-liquid mixed fluid can be industrial high-salt waste liquid that is crystallized after treatment, thereby forming a solid-liquid mixed fluid including solid crystals and residual waste liquid.

[0060] It is understandable that the first driving member 300 can be a motor or a reducer. The first driving member 300 is installed on the outer wall of the first shell 100 and can drive the rotating shaft 200 to rotate. When the rotating shaft 200 rotates, the spiral blade 210 is driven to rotate.

[0061] It is understandable that, referring to Figure 2 The first through hole 211 is provided on a side of the spiral blade 210 close to the rotating shaft 200 .

[0062] It is understood that the diameter of the first through hole 211 is smaller than the diameter of the solid particles. Since the diameter of the first through hole 211 is smaller than the diameter of the solid particles, the solid particles cannot pass through the first through hole 211. Therefore, the solid particles can be transported by the spiral blades 210 to the solid output port 110 and output from the solid output port 110.

[0063] It should be noted that the embodiment of the present application does not limit the number of the first through holes 211 , and those skilled in the art can set the number of the first through holes 211 according to actual needs.

[0064] It can be understood that the baffle assembly 400 includes a second shell 410, a cover 420, a first shaft 430, a second shaft 450, a third shaft 440, a plurality of first baffles 460 and a plurality of second baffles 470, and a first channel is formed inside the second shell 410 along the length direction of the second shell 410;

[0065] The cover 420 is covered on one end of the second shell 410; the first shaft 430 is movably provided in the cover 420, and the first shaft 430 is provided in the first channel along the length direction of the first channel; the second shaft 450 is movably provided in the cover 420, and the second shaft 450 is provided in the first channel along the length direction of the first channel; the third shaft 440 is provided in the cover 420, and the third shaft 440 is provided in the first channel along the length direction of the first channel, and the first shaft 430 and the second shaft 450 are respectively located on opposite sides of the third shaft 440; one side of the first baffle 460 is sleeved on the first shaft 430 , and the other side is sleeved on the third shaft 440. One side of the first baffle 460 is configured to be able to move along the length direction of the first channel following the first shaft 430 to adjust the relative height of one side of the first baffle 460 and the other side; one side of the second baffle 470 is sleeved on the second shaft 450, and the other side is sleeved on the third shaft 440. One side of the second baffle 470 is configured to be able to move along the length direction of the first channel following the second shaft 450 to adjust the relative height of one side of the second baffle 470 and the other side; the first baffle 460 and the second baffle 470 are alternately arranged along the length direction of the third shaft 440.

[0066] It is worth noting that, referring to Figure 1 , the baffle assembly 400 is vertically installed on the liquid outlet 130. When using the spiral conveying device of the embodiment of the present application, it is necessary to adjust the inclination angle of the first baffle 460 and the second baffle 470 according to the effect of solid-liquid separation in actual application. Since one side of the first baffle 460 is sleeved on the first shaft 430 and the other side is sleeved on the third shaft 440, when the first shaft 430 moves along the length direction of the first channel, one side of the first baffle 460 moves along the length direction of the first channel with the first shaft 430, and the other side of the first baffle 460 is relatively fixed to the third shaft 440, so the relative height of one side and the other side of the first baffle 460 can be adjusted, thereby adjusting the inclination angle of the first baffle 460; since one side of the second baffle 470 is sleeved on the second shaft 45 0, and the other side is sleeved on the third shaft 440. Therefore, when the second shaft 450 moves along the length direction of the first channel, one side of the second baffle 470 moves along the length direction of the first channel with the first shaft 430, and the other side of the second baffle 470 is relatively fixed to the third shaft 440. Therefore, the relative height of one side and the other side of the second baffle 470 can be adjusted, thereby adjusting the inclination angle of the second baffle 470; therefore, the baffle assembly 400 of the embodiment of the present application can adjust the inclination angle of the first baffle 460 and the second baffle 470.

[0067] It is worth noting that when the solid-liquid mixed fluid flows into the baffle assembly 400, Figure 7 , Figure 7 The diagram shows the flow direction of the liquid in the first channel. When blocked by the first baffle 460 and the second baffle 470, the liquid is deflected and flows away. Solid particles, on the other hand, are blocked by the first baffle 460 and the second baffle 470. The solid particles are separated from the liquid by passing through multiple first baffles 460 and multiple second baffles 470. The inclination angles of the first baffle 460 and the second baffle 470 can be adjusted according to the actual separation effect.

[0068] It should be noted that the relative height refers to the length in the longitudinal direction of the first channel.

[0069] It is understandable that the cover 420 may be engaged with one end of the second shell 410 or may be threadedly connected to one end of the second shell 410 .

[0070] It is understood that the second housing 410 is provided with a first opening 411 and a second opening 412, both of which are in communication with the first channel. The first opening 411 is provided on the sidewall of the second housing 410 at one end close to the cover 420, and the second opening 412 is provided on the end surface of the second housing 410 at one end away from the cover 420. In some embodiments, the first opening 411 can serve as the output port of the baffle assembly 400, and the second opening 412 can serve as the input port 120 of the baffle assembly 400. The fluid is input into the first channel through the second opening 412, and flows out of the first opening 411 after being deflected by the first baffle 460 and the second baffle 470. In other embodiments, the first opening 411 can serve as the input port 120 of the deflector assembly 400, and the second opening 412 can serve as the output port of the deflector assembly 400. The fluid is input into the first channel from the first opening 411, and flows out from the second opening 412 after being deflected by the first deflector 460 and the second deflector 470.

[0071] It is understood that the baffle assembly 400 of the embodiment of the present application further includes a first fixing member 431 and a second fixing member 451. The first fixing member 431 is sleeved on the first shaft 430 and is used to fix the first shaft 430 to the cover 420. The second fixing member 451 is sleeved on the second shaft 450 and is used to fix the second shaft 450 to the cover 420. The first fixing member 431 fixes the first shaft 430 to the cover 420, so that the first shaft 430 and the cover 420 are directly fixed relative to each other. The second fixing member 451 fixes the second shaft 450 to the cover 420, so that the second shaft 450 and the cover 420 are relatively fixed. When fluid is transported in the first passage, since the first shaft 430 and the second shaft 450 are fixed, the first baffle 460 and the second baffle 470 are also fixed, so that the first baffle 460 and the second baffle 470 can withstand the impact of the fluid.

[0072] In some embodiments, the first shaft 430 and the second shaft 450 are both screws, and the first fixing member 431 and the second fixing member 451 are both nuts. The nuts secure the first shaft 430 and the second shaft 450 to the cover 420, ensuring relative fixation between the second shaft 450 and the cover 420. When fluid is transported during the first pass, the first baffle 460 and the second baffle 470 are also fixed due to the fixation of the first shaft 430 and the second shaft 450, allowing the first baffle 460 and the second baffle 470 to withstand the impact of the fluid. When the angle of the first baffle 460 and the second baffle 470 needs to be adjusted, the nuts are adjusted to allow the first shaft 430 and the second shaft 450 to move relative to the cover 420. After the adjustment is complete, the nuts are used to secure the first shaft 430 and the second shaft 450. In one embodiment, the nuts are butterfly nuts.

[0073] It is understood that the third shaft 440 is movably provided in the cover 420, and the other side of the first baffle unit is configured to be able to move along the length direction of the first channel following the third shaft 440; the other side of the second baffle unit is configured to be able to move along the length direction of the first channel following the third shaft 440. In some embodiments, the third shaft 440 is a screw, and the third shaft 440 is movably provided in the cover 420, and the third shaft 440 is mounted on the cover 420 by a nut. By adjusting the nut, the third shaft 440 and the cover 420 can be fixed or movable. When adjusting the inclination angle of the first baffle 460 and the second baffle 470, since the first shaft 430, the second shaft 450, and the third shaft 440 are all movable, the first shaft 430, the second shaft 450, and the third shaft 440 can be adjusted at the same time, so the adjustment is more convenient.

[0074] It is understood that the second shell 410 is cylindrical in shape, and the side of the first baffle 460 near the sidewall of the second shell 410 is arc-shaped; the side of the second baffle 470 near the sidewall of the second shell 410 is also arc-shaped. Since the second shell 410 is cylindrical in shape, the cross-sectional shape of the sidewall of the second shell 410 is arc-shaped, and the side of the first baffle 460 near the sidewall of the second shell 410 is arc-shaped; the side of the second baffle 470 near the sidewall of the second shell 410 is also arc-shaped. Therefore, the side of the first baffle 460 near the sidewall of the second shell 410 can fit with the sidewall of the second shell 410, and the side of the second baffle 470 near the sidewall of the second shell 410 can fit with the sidewall of the second shell 410. Specifically, the second shell 410 is cylindrical, and the first baffle 460 and the second baffle 470 are fan-shaped.

[0075] It is understood that a second through-hole is defined on one side of the first baffle 460 for the first shaft 430 to pass through, and a third through-hole is defined on one side of the second baffle 470 for the second shaft 450 to pass through. In one embodiment, the first shaft 430 is a screw, and thus the sidewall of the first shaft 430 is threaded, which engages with the edge of the second through-hole. As a result, the first shaft 430 is relatively fixed to one side of the first baffle 460, and when the first shaft 430 moves, it can drive the first baffle 460. The second shaft 450 is a screw, and thus the sidewall of the second shaft 450 is threaded, which engages with the edge of the third through-hole. As a result, the second shaft 450 is relatively fixed to one side of the second baffle 470, and when the second shaft 450 moves, it can drive the second baffle 470.

[0076] It should be noted that Figure 3 and Figure 4 The second and third through holes shown are both bar-shaped holes. This is only an example and should not be construed as limiting the present application. Those skilled in the art can adjust the shapes of the second and third through holes according to actual needs. It should be noted that the first baffle 460 and the second baffle 470 have the same structure.

[0077] It is understood that a first notch is defined on the other side of the first baffle 460 for the third shaft 440 to pass through, and a second notch is defined on the other side of the second baffle 470 for the third shaft 440 to pass through. In one embodiment, the third shaft 440 is a screw having threads formed on its sidewall. The threads engage with the edge of the second notch or the edge of the first notch, thereby securing the first baffle 460 and the third shaft 440 relative to each other, and securing the second baffle 470 and the third shaft 440 relative to each other.

[0078] It can be understood that the deflector assembly 400 of the embodiment of the present application further includes a plurality of support members 442 and a plurality of support shafts 441.
