[0024] In order to make the purpose, technical scheme and advantage of the utility model embodiment more clear, the utility model technical scheme will be described clearly and completely below in conjunction with the embodiment.

[0025] Figure 1The overall structure of the mortar conveying pipeline is shown; the mortar conveying pipeline comprises a sand bucket 100, a three-way valve 200, an output pipeline 300, a return pipeline 400 and a flow meter 500, the outlet of the sand bucket 100 is communicated with the output pipeline 300 and the return pipeline 400 through the three-way valve 200, the flow meter 500 is arranged on the output pipeline 300 and used for monitoring the flow through the output pipeline 300, and the output end of the return pipeline 400 is communicated with the sand bucket 100; the sand bucket 100 is used for storing mortar and has an inlet and an outlet; the output pipeline 300 and the return pipeline 400 are arranged side by side and are not communicated with each other; the three-way valve 200 has three ports, one of which is an input port communicated with the outlet of the sand bucket 100, and the other two are output ports communicated with the output pipeline 300 and the return pipeline 400 respectively, that is, the mortar in the sand bucket 100 flows into the output pipeline 300 and the return pipeline 400 through the three-way valve 200, and the three-way valve 200 switches between the output pipeline 300 and the return pipeline 400 through an electromagnetic valve; in the standby state, the three-way valve 200 communicates the outlet of the sand bucket 100 with the return pipeline 400, and the mortar flowing out of the outlet of the sand bucket 100 flows back through the inlet of the return pipeline 400; in the cutting state, the three-way valve 200 communicates the sand bucket 100 with the output pipeline 300, and the mortar flowing out of the outlet of the sand bucket 100 flows to the cutting chamber through the output pipeline 300, and the flow meter 500 arranged on the output pipeline 300 can monitor the cutting flow.

[0026] However, flow fluctuation will interfere with the flow meter 500, thereby affecting the frequency of the sand pump.

[0027] Figure 2 The structure of the rectifier 600 is shown; Figure 2 In the output pipeline 300, the rectifier 600 is arranged between the three-way valve 200 and the flow meter 500, that is, the flow disturbed by the three-way valve 200 needs to pass through the rectifier 600 before flowing to the flow meter 500, so that the rectifier 600 is used to rectify the mortar and avoid the flow meter 500 from being disturbed by fluctuation.

[0028] The kinetic energy of the fluid flowing in the output pipeline 300 can be decomposed into axial kinetic energy, radial kinetic energy and circumferential kinetic energy.

[0029] Figure 3 The structure of the first rectification area 610 and the second rectification area 620 is shown; Figure 3 The rectifier 600 comprises the first rectification area 610 and the second rectification area 620 arranged in sequence along the flow direction, wherein the first rectification area 610 is mounted on the second rectification area 620, and the outer diameter of the second rectification area 620 matches the inner diameter of the output pipeline 300, so that the fluid must pass through the rectifier 600.

[0030] Figure 4 A structural schematic diagram of the first rectifying area 610 is shown; Figure 4 In the first rectifying area 610, a plurality of ring bodies 611 are sequentially sleeved from inside to outside, and a gap is formed between two adjacent ring bodies 611 to form an annular channel 612; the sizes of the plurality of ring bodies 611 are increasing, which can force the fluid to pass through the annular channel 612, compress the activity space of the fluid in the radial direction, thus eliminating the radial kinetic energy of the turbulence in the fluid and preliminarily rectifying the fluid; and the plurality of ring bodies 611 are coaxial with the output pipeline 300; that is, the cross sections of the plurality of ring bodies 611 and the output pipeline 300 are coaxial design, the annular channel 612 formed between two adjacent ring bodies 611 is uniform, the radial width at any position is equal, the radial width of the fluid passing through the annular channel 612 is the same at any position, the distance between two adjacent ring bodies 611 is the same, and the radial widths of the plurality of annular channels 612 are equal, so that the fluid passing through the first rectifying area 610 is still uniformly distributed in a macroscopic view.

[0031] Figure 5 A structural schematic diagram of the second rectifying area 620 is shown; Figure 5 In the second rectifying area 620, a column body 621 and a plurality of columnar channels 622 formed in the column body 621 are included, and the plurality of columnar channels 622 are regularly distributed along the annular channel 612; that is, in the cross section, each annular channel 612 corresponds to a plurality of groups of columnar channels 622, and the plurality of groups of columnar channels 622 are uniformly distributed along the shape of the annular channel 612 in the cross section; that is, the fluid passing through the second rectifying area 620 does not change on the same circle with the axis as the center, forms an axisymmetric flow pattern, and the flow conditions of the fluid in all planes including the fixed axis are the same; the columnar channel 622 is parallel to the axis of the flowmeter 500; the fluid is forced to pass through the columnar channel 622, the activity space of the fluid in the circumferential direction is compressed, thus the circumferential kinetic energy of the turbulence in the fluid can be eliminated, secondary rectification is realized, only the axial kinetic energy of the fluid is ensured, and the flow direction of the fluid passing through the columnar channel 622 is parallel to the axis, so that the fluid is quickly and stably.
