Description

Technical Field

[0001] This invention relates to the field of slurry homogenization technology, specifically to an improved slurry homogenization pump and its usage method. Background Technology

[0002] Slurry homogenizing pumps are used to shear and mix fluid materials. The equipment relies on the relative motion between the internal rotating rotor and the stationary stator to apply shearing force to the material. In actual industrial processing, existing homogenizing equipment has limitations. The material flows through the stator and rotor shearing zone once, and the number of mechanical shearings it receives is fixed. The homogenization depth is limited. The processing quality is improved by increasing the number of stator and rotor layers connected in series, but this increases the axial dimension of the equipment and the overall assembly cost. When homogenizing pumps process high-viscosity materials, the internal fluid resistance increases, causing local fluid pressure to accumulate continuously within the cavity. Forced operation of the equipment under high pressure causes overload on the drive end, resulting in internal component jamming and shutdown. Some processing steps require the addition of sensitive materials during equipment operation. The existing single-point direct injection structure of the pipeline causes the newly introduced materials to be directly subjected to the strong impact of the internal high-speed rotating components, which damages the internal morphology of the sensitive materials. The single-point centralized injection method reduces the initial contact area between the materials and the main fluid, and reduces the overall mixing uniformity. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides an improved slurry homogenizing pump and its usage method, which solves the problems of limited single-shear processing of existing homogenizing equipment, local high-pressure overload caused by high-viscosity materials, and damage to sensitive materials and uneven mixing caused by single-point feeding.

[0004] To achieve the above objectives, the present invention provides the following technical solution: The first aspect of the present invention provides an improved slurry homogenizing pump, comprising a fixed bracket and a drive motor, characterized in that the drive motor is fixedly connected to the top of the fixed bracket, a main shaft is fixedly connected to the output end of the drive motor, a sealing module is sleeved on the outside of the main shaft, a homogenizing component is disposed above the fixed bracket, the main shaft passes through the interior of the homogenizing component, a discharge component is fixedly connected to one end of the homogenizing component, a reverse pumping mechanism is disposed inside the homogenizing component, a dispersing mechanism is disposed inside the homogenizing component, and a feeding buffer mechanism is disposed outside the homogenizing component.

[0005] Preferably, the homogenizing component includes a dispersion chamber and multiple stator housings. The dispersion chamber has a feed inlet at its top. The multiple stator housings are fixedly connected to one side of the dispersion chamber. A stator gear disk is fixedly connected inside each stator housing. The main shaft passes through the dispersion chamber and the multiple stator housings. A rotor is fixedly connected to the outside of the main shaft. The rotor is coaxially arranged with the stator gear disk. The rotor extends into the inner space of the stator gear disk, and the rotor and the stator gear disk are spaced apart to form a shear gap.

[0006] Preferably, each of the stator housings is fixedly connected to a first connecting flange at both ends, a cooling jacket is provided inside the stator housing, a cooling water inlet is provided at the top of the stator housing, and a cooling water outlet is provided at the bottom of the stator housing. Both the cooling water inlet and the cooling water outlet are connected to the cooling jacket.

[0007] Preferably, the discharge assembly includes a discharge housing, a second connecting flange is fixedly connected to the outside of the discharge housing, one side of the second connecting flange is fixedly connected to the outer end face of a first connecting flange, the end face of the discharge housing has a discharge port, one end of the main shaft extends into the interior of the discharge housing, a conveying impeller is fixedly connected to the outside of the main shaft, and the conveying impeller is located inside the discharge housing.

[0008] Preferably, the anti-pumping mechanism includes a pumping housing and an anti-pumping wheel. The pumping housing is fixedly connected inside the stator housing, and the anti-pumping wheel is fixedly connected to the outside of the main shaft. The anti-pumping wheel is rotatably connected inside the pumping housing. A reflux cavity is formed on the inner side wall of the pumping housing, and the reflux cavity is located on one side of the periphery of the anti-pumping wheel.

[0009] Preferably, the dispersing mechanism includes an annular block and a pusher plate. The annular block is fixedly connected inside the stator housing. The outer peripheral surface of the annular block is provided with a plurality of dispersing grooves. The sidewall of the dispersing groove is provided with an opening. The pusher plate is slidably connected inside the stator housing. The side of the pusher plate is in contact with the end face of the annular block.

[0010] Preferably, the dispersing mechanism further includes springs, and multiple springs are fixedly connected inside the stator housing. One end of each spring is fixedly connected to the inner wall of the stator housing, and the other end of each spring is fixedly connected to the side of the push plate.

[0011] Preferably, the feeding buffer mechanism includes a middle feeding port and a retaining ring. The middle feeding port is fixedly connected to the outside of the stator housing. The retaining ring is fixedly connected to the bottom end of the middle feeding port. An annular spiral cavity is opened inside the retaining ring. The bottom end of the middle feeding port is connected to the inside of the annular spiral cavity.

[0012] Preferably, the feeding buffer mechanism further includes through holes. Multiple through holes are provided on the outer wall of the stator housing. The multiple through holes are distributed in a circumferential array. One end of the through hole is connected to the interior of the annular spiral cavity, and the other end of the through hole is connected to the interior of the stator housing.

[0013] A second aspect of the present invention provides a method for using an improved slurry homogenizing pump, comprising the following steps: Step 1: Start the drive motor. The output of the drive motor drives the main shaft to rotate. The slurry enters the dispersion chamber and stator housing through the feed port. The main shaft drives the rotor to rotate relative to the stator toothed disc. The slurry flows through the shear gap formed by the rotor and the stator toothed disc and is sheared under the action of the relative motion between the rotor and the stator toothed disc. The cooling medium enters the cooling jacket through the cooling water inlet and then flows out through the cooling water outlet. Step 2: The main shaft drives the reverse pumping wheel to rotate inside the pumping housing. Part of the slurry flows through the return chamber and back into the stator housing. The returned slurry re-enters the shear gap formed between the rotor and the stator gear plate and is sheared again under the action of the relative motion between the rotor and the stator gear plate. Step 3: When the slurry pressure inside the stator housing increases, the slurry squeezes and pushes the pusher plate to slide inside the stator housing. The pusher plate compresses the spring, and some slurry flows out from the dispersion groove and opening around the annular block. When the slurry pressure inside the stator housing decreases, the spring extends and drives the pusher plate to slide back to its original position. Step 4: External material enters through the middle feed port, flows through the baffle ring and enters the annular spiral cavity, and then the material flows through multiple through holes into the stator housing and mixes with the slurry inside the stator housing; Step 5: The slurry flows into the discharge shell, and the main shaft drives the conveying impeller to rotate and pressurize the slurry. After being pressurized, the slurry is discharged from the discharge port.

[0014] This invention provides an improved slurry homogenizing pump and its usage method. It has the following beneficial effects: 1. The present invention uses a feeding buffer mechanism to allow external materials to enter through the middle feeding port. After being blocked by the contact baffle ring, the materials flow into the annular spiral cavity and diffuse along the channel. Subsequently, they are fed into the stator housing through multiple through holes arranged in a circumferential array. This transforms the single-point concentrated addition of materials into a circumferentially multi-point uniform addition, avoiding direct impact of sensitive materials on internal high-speed components and playing a pre-buffering role. At the same time, it improves the mixing uniformity when the added materials and the main slurry are combined.

[0015] 2. This invention utilizes a dispersion mechanism to address the issue of high pressure caused by high viscosity or accumulation of slurry inside the stator housing. The accumulated high-pressure slurry pushes the pusher plate to overcome the spring force and slide, exposing the dispersion grooves and openings around the annular blockage. This allows some slurry to flow out and be diverted. After the pressure decreases, the spring extends and pushes the pusher plate back to its original position to seal the blockage. This mechanism can automatically release pressure and divert flow based on the internal pressure of the cavity, reducing local resistance and operating load, and minimizing the risk of equipment blockage and overload.

[0016] 3. The present invention uses a reverse pumping mechanism, in which the main shaft drives the reverse pumping wheel to rotate inside the pumping housing to push the slurry. With the flow direction restriction of the outer return cavity, part of the forward-moving slurry is guided to turn back. The returned slurry re-enters the shearing gap formed between the rotor and stator gear plate to be sheared again. Without increasing the number of stator and rotor stages, the residence time and number of shearings of the slurry in the effective shearing area are increased, thereby improving the overall homogeneous processing quality.

The cooling medium enters the cooling jacket 408 through the cooling water inlet 406 and then flows out through the cooling water outlet 407. Step 2: The main shaft 6 drives the reverse pumping wheel 703 to rotate inside the pumping housing 701. Part of the slurry flows through the return chamber 702 and back into the stator housing 403. The returned slurry re-enters the shear gap formed between the rotor 405 and the stator gear disk 404, and is sheared again under the action of the relative motion between the rotor 405 and the stator gear disk 404. Step 3: When the slurry pressure inside the stator housing 403 increases, the accumulated slurry pushes the pusher plate 905 to slide inside the stator housing 403. The pusher plate 905 compresses the spring 904, and some slurry flows out from the dispersion groove 902 and opening 903 around the annular block 901. When the slurry pressure inside the stator housing 403 decreases, the spring 904 extends and drives the pusher plate 905 to slide back to its original position. Step 4: External material enters through the middle feed port 801, flows through the baffle ring 802 and enters the annular spiral cavity 803, and then the material flows through multiple through holes 804 into the stator housing 403 and mixes with the slurry inside the stator housing 403.

Step 3: When the slurry pressure inside the stator housing (403) increases, the slurry squeezes and pushes the pusher plate (905) to slide inside the stator housing (403). The pusher plate (905) compresses the spring (904), and some slurry flows out from the dispersion groove (902) and opening (903) around the annular block (901). When the slurry pressure inside the stator housing (403) decreases, the spring (904) extends and drives the pusher plate (905) to slide back to its original position. Step 4: External material enters through the middle feed port (801), flows through the baffle ring (802) and enters the annular spiral cavity (803). Subsequently, the material flows through multiple through holes (804) into the stator housing (403) and mixes with the slurry inside the stator housing (403). Step 5: The slurry flows into the discharge shell (501), and the main shaft (6) drives the conveying impeller (504) to rotate and pressurize the slurry. After being pressurized, the slurry is discharged from the discharge port (503).
