Description

Technical Field

[0001] This utility model relates to the field of emulsification pump technology, specifically a multi-stage impeller coupled emulsification pump. Background Technology

[0002] Multistage impeller coupled emulsifying pumps are industrial equipment that combine multistage impeller structure with emulsification and shearing functions. They are mainly used for efficient mixing, homogenization and emulsification of high viscosity or difficult-to-mix solutions. Their design enhances shearing and flow control step by step through the synergistic effect of multistage impellers, significantly improving emulsification efficiency and product quality.

[0003] Existing multi-stage impeller-coupled emulsifying pumps directly draw in liquid for initial mixing. The liquid to be emulsified enters the pump body through the inlet pipe. Before the first impeller, the liquid may pass through a static mixer or flow guide device for initial mixing, forming a coarse emulsion. The high-speed rotation of the impeller generates centrifugal force, throwing the liquid towards the pump casing, forming a high-pressure area. The shear force between the impeller blades and the liquid breaks up large droplets, achieving primary emulsification. Each impeller stage gradually increases the liquid pressure, enhancing the subsequent shearing effect. Some designs have a fixed shear ring (stator) after the impeller, generating high-shear turbulence through the impeller-stator gap to further break up the droplets. Typically, 3-5 impellers are connected in series, with each stage refining the droplet size, ultimately achieving submicron-level dispersion. Some systems are equipped with a return pipe, returning unqualified liquid to the inlet for reprocessing to ensure emulsification uniformity. High-speed shearing may generate heat, so an internal cooling jacket or external heat exchanger controls the temperature to prevent denaturation of heat-sensitive components. After being processed by the final impeller, the emulsion is discharged through the outlet pipe for filtration before entering a storage tank or the next process.

[0004] Existing multi-stage impeller-coupled emulsifying pumps still have the following shortcomings:

[0005] 1. When viscous or particulate materials enter a multi-stage impeller coupled emulsifying pump, excessive material or excessive speed will increase the working efficiency of the multi-stage impeller coupled emulsifying pump, affect its service life, and cause material to clog the feed hole of the multi-stage impeller coupled emulsifying pump.

[0006] 2. After the material is emulsified by the multi-stage impeller coupled emulsifying pump, the emulsified material needs to be discharged. The existing multi-stage impeller coupled emulsifying pump filters the material during discharge. Over time, the filter screen will become clogged and needs to be replaced. This requires disassembling the multi-stage impeller coupled emulsifying pump, which is quite cumbersome.

[0007] Therefore, we propose a multi-stage impeller-coupled emulsifying pump to solve the problems mentioned above. Utility Model Content

[0008] The purpose of this invention is to provide a multi-stage impeller coupled emulsifying pump to solve the problems mentioned in the background art, such as the blockage of the feed inlet by viscous or particulate materials when entering the multi-stage impeller coupled emulsifying pump, and the inconvenience of replacing the filter screen at the discharge port of the multi-stage impeller coupled emulsifying pump.

[0009] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0010] A multi-stage impeller-coupled emulsifying pump includes a pump body. A metering tube is fixedly connected to the inlet end of the pump body. A metering mechanism for metering material feeding is installed on the inner wall of the metering tube. A feed pipe is fixedly connected to the inlet end of the metering tube. A cutting roller to prevent material blockage is rotatably connected inside the feed pipe. A discharge pipe is fixedly connected to the outlet end of the pump body. An adjusting plate is rotatably connected to one end of the discharge pipe. Multiple filter plates for easy replacement are arranged in a ring array on the inner wall of the adjusting plate. A limiting mechanism for fixing the multiple filter plates is installed on the surface of the adjusting plate.

[0011] The quantitative mechanism includes a quantitative wheel plate rotatably connected to the inner wall of the quantitative tube, and the surface of the quantitative wheel plate is slidably connected to the inner wall of the quantitative tube. One end of the quantitative wheel plate is equipped with a transmission component that drives the cutting roller to rotate.

[0012] The quantitative wheel plates are divided into multiple guide troughs of equal size.

[0013] The metering mechanism also includes a motor fixedly connected to the surface of the metering tube, and the output shaft of the motor is fixedly connected to one end of the metering wheel plate.

[0014] The transmission assembly includes a timing wheel one fixedly connected to one end of the metering wheel plate, a timing belt meshing on the surface of the timing wheel one, a timing wheel two meshing on the inner wall of the timing belt, and one end of the timing wheel two fixedly connected to one end of the cutting roller.

[0015] The regulating plate is slidably connected between the discharge pipe and the discharge end of the multi-stage impeller coupled emulsifying pump body.

[0016] The limiting mechanism includes multiple threaded holes on the surface of the adjusting plate, and a fixing bolt passes through one end of the discharge pipe. The threaded end of the fixing bolt is connected to the multiple threaded holes.

[0017] The multiple filter plates correspond to the multiple threaded holes.

[0018] Multiple filter plates are fixedly installed inside the regulating plate, and the size of the multiple filter plates is consistent with the discharge pipe and the discharge end of the multi-stage impeller coupled emulsifying pump body.

[0019] The bottom of the multi-stage impeller coupled emulsifying pump body is fixedly connected to a base plate that stabilizes the multi-stage impeller coupled emulsifying pump body.

[0020] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0021] Sticky or granular materials are placed in the feed pipe. A cutting roller cuts the material to prevent blockage. Once the material reaches the metering tube, a motor drives a metering wheel to rotate within it. The material is then fed into the multi-stage impeller-coupled emulsifying pump's inlet via multiple equally sized guide troughs between the metering wheels. The rotating metering wheel drives synchronous pulley one, which in turn drives synchronous belt drive synchronous pulley two. Synchronous pulley two then drives the cutting roller to rotate within the feed pipe, further cutting the sticky or granular material. This process facilitates the cutting and metering of the material, preventing blockage at the multi-stage impeller-coupled emulsifying pump's inlet.

[0022] When the filter plate needs to be replaced, loosen the fixing bolts and then rotate the adjusting plate. The adjusting plate will move the filter plates in other positions to the discharge pipe between the discharge pipe and the discharge end of the multi-stage impeller coupled emulsifying pump body. When rotating the adjusting plate, it will block the discharge pipe and the discharge end of the multi-stage impeller coupled emulsifying pump body, ensuring that the emulsified material will not leak. Then, the fixing bolts, with one end threaded through the discharge pipe, are connected to multiple threaded holes to fix the adjusting plate, facilitating the replacement of the filter plate and improving the production efficiency of the multi-stage impeller coupled emulsifying pump body.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-4 This utility model provides a technical solution:

[0030] like Figures 1-3 As shown, a multi-stage impeller-coupled emulsifying pump includes a multi-stage impeller-coupled emulsifying pump body 1. A metering tube 3 is fixedly connected to the feed end of the multi-stage impeller-coupled emulsifying pump body 1. A metering mechanism for metering material feeding is installed on the inner wall of the metering tube 3. A feed pipe 4 is fixedly connected to the feed end of the metering tube 3. A cutting roller 10 to prevent material blockage is rotatably connected inside the feed pipe 4. A discharge pipe 11 is fixedly connected to the discharge end of the multi-stage impeller-coupled emulsifying pump body 1. An adjusting plate 12 is rotatably connected to one end of the discharge pipe 11. Multiple filter plates 13 for easy replacement are arranged in a ring array on the inner wall of the adjusting plate 12. A limiting mechanism for fixing the multiple filter plates 13 is installed on the surface of the adjusting plate 12.

[0031] like Figures 1-3 As shown, a sticky or particulate material is placed in the feed pipe 4. The cutting roller 10 cuts the sticky or particulate material to prevent clogging. The sticky or particulate material then reaches the metering pipe 3. The metering mechanism ensures that the sticky or particulate material is metered into the multi-stage impeller coupled emulsifying pump body 1, preventing clogging of the feed end of the multi-stage impeller coupled emulsifying pump body 1. The material is then emulsified by the multi-stage impeller coupled emulsifying pump body 1. The emulsified material is filtered through the filter plate 13 and then discharged through the discharge pipe 11. When the filter plate 13 needs to be replaced, the adjusting plate 12 is rotated to move other filter plates 13 to the discharge pipe 11. The adjusting plate 12 is fixed by the limiting mechanism to complete the quick replacement of the filter plate 13.

[0032] Furthermore, such as Figures 1-3 As shown, the metering mechanism includes a metering wheel plate 6 rotatably connected to the inner wall of the metering tube 3, and the surface of the metering wheel plate 6 is slidably connected to the inner wall of the metering tube 3. A transmission component that drives the cutting roller 10 to rotate is installed at one end of the metering wheel plate 6.

[0033] The metering wheel plate 6 is divided into multiple guide troughs of equal size.

[0034] The metering mechanism also includes a motor 5 fixedly connected to the surface of the metering tube 3, and the output shaft of the motor 5 is fixedly connected to one end of the metering wheel plate 6.

[0035] When viscous or particulate materials arrive in the metering tube 3, the motor 5 drives the metering wheel plate 6 to rotate inside the metering tube 3. The materials are then conveyed in equal amounts to the inlet of the multi-stage impeller-coupled emulsifying pump body 1 through the multi-stage equal-sized guide troughs between the metering wheel plates 6.

[0036] Furthermore, such as Figure 1 and Figure 3 As shown, the transmission assembly includes a timing wheel 7 fixedly connected to one end of the metering wheel plate 6. The surface of the timing wheel 7 is engaged with a timing belt 8, and the inner wall of the timing belt 8 is engaged with a timing wheel 9. One end of the timing wheel 9 is fixedly connected to one end of the cutting roller 10.

[0037] When the metering wheel plate 6 rotates, it drives the synchronous wheel 7 to rotate, which in turn drives the synchronous belt 8 to drive the synchronous wheel 9. The synchronous wheel 9 then drives the cutting roller 10 to rotate inside the feed pipe 4, cutting materials that are sticky or contain particles.

[0038] Furthermore, such as Figure 1 , Figure 2 and Figure 4 As shown, the regulating plate 12 is slidably connected between the discharge pipe 11 and the discharge end of the multi-stage impeller coupled emulsifying pump body 1.

[0039] The limiting mechanism includes multiple threaded holes 14 on the surface of the adjusting plate 12, and a fixing bolt 15 passes through one end of the discharge pipe 11. The threaded end of the fixing bolt 15 is connected to the multiple threaded holes 14.

[0040] Multiple filter plates 13 correspond to multiple threaded holes 14.

[0041] Multiple filter plates 13 are fixedly installed inside the regulating plate 12, and the size of the multiple filter plates 13 is consistent with the discharge pipe 11 and the discharge end of the multi-stage impeller coupled emulsifying pump body 1.

[0042] When the filter plate 13 needs to be replaced, loosen the fixing bolt 15, and then rotate the adjusting plate 12. The adjusting plate 12 will drive the filter plates 13 in other positions to the discharge pipe 11 and the discharge end of the multi-stage impeller coupled emulsifying pump body 1. When rotating the adjusting plate 12, the adjusting plate 12 will block the discharge pipe 11 and the discharge end of the multi-stage impeller coupled emulsifying pump body 1, ensuring that the emulsified material will not leak. Then, the fixing bolt 15 is threaded through the discharge pipe 11 and connected to multiple threaded holes 14 to fix the adjusting plate 12, which makes it convenient to replace the filter plate 13.

[0043] Furthermore, such as Figure 1 and Figure 2 As shown, the bottom of the multi-stage impeller coupled emulsifying pump body 1 is fixedly connected to a base plate 2 to stabilize the multi-stage impeller coupled emulsifying pump body 1.

[0044] This design facilitates stable placement of the multi-stage impeller-coupled emulsifying pump body 1 and also protects the bottom of the multi-stage impeller-coupled emulsifying pump body 1.

[0045] The working principle of this multi-stage impeller coupled emulsifying pump is as follows:

[0046] Sticky or granular materials are placed in the feed pipe 4. The cutting roller 10 cuts the sticky or granular materials to prevent blockage. After the sticky or granular materials reach the metering pipe 3, the motor 5 drives the metering wheel plate 6 to rotate in the metering pipe 3. The material is delivered in equal amounts to the feed inlet of the multi-stage impeller coupled emulsifying pump body 1 through multiple equal-sized guide troughs between the metering wheel plates 6. When the metering wheel plate 6 rotates, it drives the synchronous wheel 7 to rotate, which in turn drives the synchronous belt 8 to drive the synchronous wheel 9. The synchronous wheel 9 then drives the cutting roller 10 to rotate in the feed pipe 4 to cut the sticky or granular materials. This facilitates the cutting and metering of sticky or granular materials and prevents them from clogging the feed inlet of the multi-stage impeller coupled emulsifying pump body 1.

[0047] When the filter plate 13 needs to be replaced, loosen the fixing bolt 15, and then rotate the adjusting plate 12. The adjusting plate 12 will drive the filter plates 13 in other positions to the discharge pipe 11 and the discharge end of the multi-stage impeller coupled emulsifying pump body 1. When rotating the adjusting plate 12, the adjusting plate 12 will block the discharge pipe 11 and the discharge end of the multi-stage impeller coupled emulsifying pump body 1, ensuring that the emulsified material will not leak. Then, the fixing bolt 15 is threaded through the discharge pipe 11 and connected to multiple threaded holes 14 to fix the adjusting plate 12, which facilitates the replacement of the filter plate 13 and improves the production efficiency of the multi-stage impeller coupled emulsifying pump body 1.

[0048] Although specific embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these specific embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
