DETAILED DESCRIPTION

[0019] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0020] Example

[0021] This embodiment provides a two-stage high-speed shearing machine, which includes a main body 1, a shearing blade 2 and a driving device 3. The main body 1 includes a transmission barrel section 11 and a dispersion barrel section 12 along its axial direction, and the bottom end of the transmission barrel section 11 is connected to the top end of the dispersion barrel section 12. A sealing partition 13 is provided between the transmission barrel section 11 and the dispersion barrel section 12. Figures 1 to 4 As shown, the figure schematically shows a preferred solution, the transmission barrel section 11 is a barrel structure with openings at the upper and lower ends respectively; the dispersion barrel section 12 is a barrel structure with an opening at the upper end and a closed lower end. The bottom end of the transmission barrel section 11 is flange-connected with the top end of the dispersion barrel section 12. The flange structure at the bottom end of the transmission barrel section 11 is defined as the first flange structure 112, and the flange structure at the top end of the dispersion barrel section 12 is defined as the second flange structure 123. The first flange structure 112 is preferably the same specification as the second flange structure 123. The sealing baffle 13 is arranged between the first flange structure 112 and the second flange structure 123, and is preferably consistent in shape and size with the first flange structure 112 or the second flange structure 123. The first flange structure 112, the sealing baffle 13 and the second flange structure 123 are locked and fixed by a first locking member 5 such as a plurality of bolts.

[0022] A plurality of seat bearings 4 are arranged in the inner cavity of the transmission cylinder section 11 along the axial direction thereof, such as Figure 3 and Figure 4As shown in , preferably, two annular fixing bosses 114 distributed along the axial direction are provided on the inner wall of the transmission barrel section 11, and the seat bearing 4 is fixed to the fixing bosses 114 by a first fastener 7 such as a bolt. The barrel wall of the transmission barrel section 11 is preferably provided with a through hole 111 communicating with its inner cavity, such as Figure 1 and Figure 2 As shown in , the through opening 111 is preferably provided at the position corresponding to the fixed boss 114. During assembly, the seat bearing 4 can be placed on the fixed boss 114 in the transmission cylinder section 11 through the through opening 111, and it is also convenient for the assembler to use tools to fix the seat bearing 4. In addition, during use, the through opening 111 can also play a role in ventilation and heat dissipation, which can extend the service life of the seat bearing 4, and it is also convenient for the maintenance personnel to add lubricating oil to the seat bearing 4.

[0023] The rotating shaft 21 of the shearing paddle 2 is arranged to penetrate the sealing partition 13. Specifically, a through hole 131 is arranged on the sealing partition 13 to connect the inner cavity of the transmission cylinder section 11 and the inner cavity of the dispersion cylinder section 12. The rotating shaft 21 of the shearing paddle 2 can rotatably pass through the through hole 131. Figure 3 and Figure 4 As shown. The upper part of the rotating shaft 21 is located in the inner cavity of the transmission barrel section 11 and is rotatably connected to the transmission barrel section 11 through the seat bearing 4. The lower part of the rotating shaft 21 is located in the inner cavity of the dispersion barrel section 12 and is provided with a shearing gear 22. The shearing gear 22 can be one, or two or more, and a plurality of the shearing gears 22 are distributed along the axial direction of the rotating shaft 21. The use of the shearing gear 22 can make the sludge magnetic seed flocs in the dispersion barrel section 12 highly dispersed when it rotates at a high speed. The shearing gear 22 is preferably made of wear-resistant material, such as alloy steel. There are many forms of fixing between the shearing gear 22 and the rotating shaft 21, such as Figure 3 and Figure 4 The second fastener 8 shown in FIG. 1 is directly locked and fixed with the rotating shaft 21 by a bolt or the like. The cylinder wall of the dispersion cylinder section 12 is provided with an inlet 121 and an outlet 122 respectively connected to the inner cavity thereof. Preferably, the inlet 121 is located below the outlet 122, and the shearing gear 22 is located between the inlet 121 and the outlet 122.

[0024] The rotating shaft 21 of the shearing paddle 2 and the sealing partition 13 are preferably sealed, and further preferably sealed by a skeleton oil seal 132, such as Figure 3 and Figure 4As shown in , a fixing seat 133 is fixedly arranged at the through hole 131 for fixing and installing the skeleton oil seal 132. Since the skeleton oil seal 132 is an existing product and its specific setting method is also a conventional technology, it will not be described in detail here. By setting the skeleton oil seal 132 to seal between the rotating shaft 21 and the sealing partition 13, it is possible to prevent the liquid in the dispersion barrel section 12 from splashing out, and the liquid in the dispersion barrel section 12 can play the effect of cooling the skeleton oil seal 132.

[0025] In a further preferred embodiment, the sealing partition 13 and the first flange structure 112 are preferably locked and fixed by a second locking member 6 such as a plurality of bolts, for example Figures 3 to 5 As shown in FIG, the sealing baffle 13 and the first flange structure 112 are locked and fixed by two second locking members 6. With such a design, the driving device 3, the shearing blade 2, the transmission cylinder section 11 and the sealing baffle 13 can be assembled into a whole when assembling. Figure 5 As shown, it is then assembled with the dispersion cylinder section 12, and disassembly is relatively convenient. Especially when the shearing gear 22 of the shearing paddle 2 needs to be replaced, it is only necessary to loosen the first locking piece 5, and the operation is simple and convenient.

[0026] The driving device 3 is preferably a high-speed motor, which is fixedly arranged at the top of the transmission barrel section 11. Preferably, the driving end of the high-speed motor is connected to the top of the transmission barrel section 11 by a flange. The flange structure at the top of the transmission barrel section 11 is defined as a third flange structure 113, and the flange structure at the driving end of the high-speed motor is defined as a fourth flange structure 31. The third flange structure 113 is preferably the same as the fourth flange structure 31. The third flange structure 113 and the fourth flange structure 31 are locked and fixed by a third locking member such as a plurality of bolts, such as Figure 1 and Figure 2 The driving shaft 32 of the high-speed motor extends into the inner cavity of the transmission cylinder section 11 and is connected to the rotating shaft 21 of the shearing blade 2, preferably through a coupling 9, as shown. Figure 3 and Figure 4As shown, its structure is simple and easy to assemble. Since the coupling 9 is an existing product and its setting method is also conventional technology, it will not be described in detail here. During specific implementation, the high-speed motor is powered on, the shaft 21 of the high-speed motor rotates at high speed, and the shearing paddle 2 is also driven by the coupling 9 to rotate at high speed. The high tangential speed and high-frequency mechanical effect generated by the high-speed rotation of the shearing gear 22 will cause the sludge magnetic seed flocs to be subjected to strong mechanical and hydraulic shearing, centrifugal extrusion, liquid layer friction, impact tearing and turbulence in the narrow dispersion barrel section 12. The high-speed movement forms turbulence, and the sludge magnetic seed flocs are fully dispersed, emulsified, and broken, thereby achieving the effect required for magnetic seed separation and recovery. Finally, they are discharged from the outlet 122 of the dispersion barrel section 12 and enter the next step of the magnetic seed separation and recovery process.

[0027] The two-stage high-speed shearing machine of the present application has a two-stage main body 1 with an ingenious and simple structural design and is easy to assemble. A sealing baffle 13 is provided to isolate the transmission barrel section 11 and the dispersion barrel section 12, so that liquid in the dispersion barrel section 12 can be prevented from splashing out. The sealing baffle 13 is preferably designed to be fixedly connected to the transmission barrel section 11. During assembly, the driving device 3, the shearing paddle 2, the transmission barrel section 11 and the sealing baffle 13 can be assembled into a whole before being assembled with the dispersion barrel section 12. Assembly and disassembly are relatively convenient, especially when the shearing gear 22 of the shearing paddle 2 needs to be replaced, it is only necessary to loosen the locking piece between the transmission barrel section 11 and the dispersion barrel section 12, and the operation is simple and convenient.
