Description

Technical Field

[0001] This utility model relates to the field of emulsification pump technology, specifically a coaxial multi-functional homogenizing emulsification pump. Background Technology

[0002] In industrial fields such as food processing, pharmaceutical preparation, and fine chemicals, homogenizing emulsifying pumps are key equipment for achieving efficient material handling. Their core working principle involves the precise coordination of the rotor and stator to generate strong shearing forces, impact forces, and turbulence effects during high-speed rotation, thereby completing the mixing, homogenization, dispersion, pulverization, and emulsification of materials, ultimately improving the texture uniformity, stability, and performance of the product. This equipment is typically installed on pipelines for continuous online processing, effectively eliminating batch-to-batch quality variations. Its basic structure mainly consists of a pump chamber that bears the power, and a pair of stator and rotors that perform the core processing functions.

[0003] However, existing homogenizing emulsifying pumps suffer from two major technical defects in practical applications, severely restricting their user experience and operational reliability. Firstly, the equipment generally lacks dedicated noise reduction structures. The continuous noise generated by the high-speed motor operation not only affects the hearing health of operators but may also exceed noise emission standards in industrial workshops, disrupting the stability of the production environment. Secondly, the heat dissipation design of existing equipment is relatively simple, making it difficult to quickly dissipate the heat generated during motor operation. Prolonged high-temperature environments not only accelerate the aging of the motor insulation layer and shorten the equipment's lifespan but may also lead to decreased motor efficiency, unstable start-stop operation, and even equipment failure due to excessive temperature. Furthermore, high temperatures may adversely affect the processing quality of heat-sensitive materials.

[0004] Therefore, given the shortcomings of existing homogenizing emulsifying pumps in terms of noise reduction and heat dissipation, it is urgent to optimize their structural design to solve the problem of poor noise reduction and heat dissipation, thereby improving the operational stability, user comfort, and applicability of the equipment. Utility Model Content

[0005] To address the problems mentioned in the background section, the present invention aims to provide a coaxial multi-functional homogenizing emulsifier pump with advantages of good noise reduction and heat dissipation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a coaxial multi-functional homogenizing emulsifying pump, comprising an emulsifying pump body, a noise-reducing air box fixedly connected to the bottom of the emulsifying pump body, a noise-reducing cover fixedly connected to the top of the emulsifying pump body, an opening on the top of the noise-reducing air box communicating with the noise-reducing cover, air inlet pipes connected to both sides of the top of the noise-reducing cover, a fan fixedly connected inside the air inlet pipes via a bracket, a motor of the emulsifying pump body located inside the noise-reducing cover, the air inlet pipes, the noise-reducing cover, and the noise-reducing air box all comprising a base layer, a first sound-absorbing layer fixedly connected to the surface of the base layer, a second sound-absorbing layer fixedly connected to the surface of the first sound-absorbing layer, and a sound-insulating layer fixedly connected to the surface of the second sound-absorbing layer.

[0007] As a preferred embodiment of this invention, dustproof nets are fixedly connected to both the air inlet of the air inlet pipe and the air outlet of the noise reduction fan box.

[0008] As a preferred embodiment of this utility model, noise reduction perforated plates are fixedly connected to the front and rear sides of the inner wall of the noise reduction cover, and the number of noise reduction perforated plates is several, and the noise reduction perforated plates are evenly distributed on the inner wall of the noise reduction cover.

[0009] As a preferred embodiment of this utility model, the inner wall of the noise reduction air box is fixedly connected with a noise reduction frame and a noise reduction wave plate, and the number of noise reduction frames and noise reduction wave plates is several, and the noise reduction frames and noise reduction wave plates are arranged alternately.

[0010] As a preferred embodiment of this invention, the inner wall of the air intake pipe is provided with a plurality of noise-reducing grooves that are evenly distributed in a ring shape.

[0011] As a preferred embodiment of this utility model, the base layer is made of stainless steel, the first sound-absorbing layer is made of open-cell polyurethane foam, the second sound-absorbing layer is made of centrifugal glass wool, and the sound insulation layer is made of damping sound insulation board.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model employs a noise-reducing air box fixed at the bottom of the emulsifying pump body and a noise-reducing cover fixed at the top, with the two connected by a vent. Simultaneously, fans are installed in the air inlet pipes on both sides of the noise-reducing cover via brackets, constructing a complete heat dissipation system. When the fans are running, they drive airflow from the air inlet pipes into the noise-reducing cover. Inside the cover, the airflow contacts the emulsifying pump body and motor, absorbs heat, and then enters the noise-reducing air box through the vent and is finally discharged. This effectively solves the problem of poor heat dissipation and difficulty in timely heat dissipation leading to excessively high temperatures in existing emulsifying pumps. Furthermore, the air inlet pipes, noise-reducing cover, and noise-reducing air box all adopt a multi-layered structure design. The base layer ensures structural stability, the first and second sound-absorbing layers absorb noise generated by the motor operation layer by layer, and the outer sound insulation layer blocks noise from propagating outwards. This completely solves the problem of existing emulsifying pumps lacking noise reduction structures and causing noise to affect users, significantly improving the stability of equipment operation and user comfort. This device has the advantages of excellent noise reduction and heat dissipation effects.

[0013] 2. This utility model effectively prevents dust, impurities, and other foreign objects from entering the equipment by fixing dustproof nets at the air inlet of the air intake pipe and the air outlet of the noise reduction fan box. Without dustproof nets, dust easily adheres to the surface of the fan inside the air intake pipe, causing a decrease in fan speed and heat dissipation efficiency. It may also accumulate on the surface of the sound-absorbing and sound-insulating layers of the noise reduction cover and noise reduction fan box, clogging pores and weakening noise reduction performance, and even entering the motor, causing component wear and failure. The dustproof nets can maintain the cleanliness of the equipment's interior for a long time, ensuring smooth airflow in the heat dissipation system and the performance stability of the noise reduction structure, reducing maintenance needs and failure risks caused by dust, extending the overall service life of the equipment, and ensuring its long-term efficient operation.

[0016] 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.

[0017] like Figures 1 to 5 As shown, a coaxial multi-functional homogenizing emulsifying pump includes an emulsifying pump body 1. A noise-reducing air box 2 is fixedly connected to the bottom of the emulsifying pump body 1, and a noise-reducing cover 3 is fixedly connected to the top of the emulsifying pump body 1. The top of the noise-reducing air box 2 has an opening 4, which communicates with the noise-reducing cover 3. Air inlet pipes 5 are connected to both sides of the top of the noise-reducing cover 3. A fan is fixedly connected to the inside of the air inlet pipe 5 through a bracket. The motor of the emulsifying pump body 1 is located inside the noise-reducing cover 3. The air inlet pipe 5, the noise-reducing cover 3, and the noise-reducing air box 2 all include a base layer 6. A first sound-absorbing layer 7 is fixedly connected to the surface of the base layer 6. A second sound-absorbing layer 8 is fixedly connected to the surface of the first sound-absorbing layer 7. A sound-insulating layer 9 is fixedly connected to the surface of the second sound-absorbing layer 8. The standard parts used in this utility model can all be purchased from the market. Purchased on-site, irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the existing technology. The machinery, parts and equipment adopt conventional models in the existing technology. The contents not described in detail in this specification belong to the prior art known to those skilled in the art. This application will not describe them in detail. The emulsifying pump body 1 mentioned above is similar in principle to the emulsifying pump body 1 mentioned in the utility model patent with publication (announcement) number: CN218166591U, and achieves the same effect. This application will not describe it in detail. The airflow enters the noise reduction cover 3 from the air inlet pipe 5, then enters the noise reduction air box 2 through the through hole, and then exits from the left air outlet of the noise reduction air box 2.

[0018] refer to Figure 1 Dustproof nets 10 are fixedly connected to the air inlet of the air inlet pipe 5 and the air outlet of the noise reduction air box 2.

[0019] As a technical optimization of this utility model, by fixing dustproof nets 10 at the air inlet of the air inlet pipe 5 and the air outlet of the noise reduction fan box 2, dust, impurities, and other foreign objects in the outside air can be effectively blocked from entering the equipment. Without the dustproof nets 10, dust easily adheres to the surface of the fan inside the air inlet pipe 5, causing a decrease in fan speed and heat dissipation efficiency. It may also accumulate on the surfaces of the sound-absorbing and sound-insulating layers 9 of the noise reduction cover 3 and the noise reduction fan box 2, clogging pores and weakening noise reduction performance, and even entering the motor, causing component wear and malfunction. The dustproof nets 10 maintain the cleanliness of the equipment's interior for a long time, ensuring smooth airflow in the heat dissipation system and the performance stability of the noise reduction structure, reducing maintenance needs and malfunction risks caused by dust, extending the overall service life of the equipment, and ensuring its long-term efficient operation. The dustproof net 10 inside the air outlet on the left side of the noise reduction fan box 2 is not shown.

[0020] refer to Figure 2 Noise reduction plates 11 are fixedly connected to the front and rear sides of the inner wall of the noise reduction cover 3. There are several noise reduction plates 11, which are evenly distributed on the inner wall of the noise reduction cover 3.

[0021] As a technical optimization of this utility model, by fixing noise-reducing perforated plates 11 to the front and rear sides of the inner wall of the noise-reducing cover 3, the noise inside the noise-reducing cover 3 can be weakened a second time. When the noise generated by the motor propagates inside the noise-reducing cover 3, some of the noise will enter the channels of the noise-reducing perforated plates 11. The air vibration in the channels will consume the noise energy, further reducing the noise intensity. Combined with the multi-layer sound absorption and sound insulation structure of the noise-reducing cover 3 itself, a dual noise reduction effect is formed, making the noise reduction effect better. At the same time, the noise-reducing perforated plates 11 adopt a hollow design, which will not obstruct the airflow path inside the noise-reducing cover 3, ensuring that the cooling airflow driven by the fan can smoothly contact the motor and carry away the heat, avoiding the impact of adding noise-reducing components on the heat dissipation effect. This design not only enhances the noise reduction performance, but also ensures the normal operation of the heat dissipation system, allowing the equipment to maintain good heat dissipation efficiency in a low-noise environment, improving the user's operating experience.

[0022] refer to Figure 2 The inner wall of the noise reduction air box 2 is fixedly connected with a noise reduction frame 12 and a noise reduction wave plate 13. There are several noise reduction frames 12 and noise reduction wave plates 13, and the noise reduction frames 12 and noise reduction wave plates 13 are arranged in an alternating manner.

[0023] As a technical optimization of this utility model, by fixing staggered noise-reducing frames 12 and noise-reducing corrugated plates 13 on the inner wall of the noise-reducing air box 2, the noise reduction function of the air box can be enhanced simultaneously. The noise transmitted from the motor to the air box will be reflected and collided multiple times between the noise-reducing frames 12 and the noise-reducing corrugated plates 13. Each reflection will consume some noise energy, and the irregular surface of the corrugated plates can increase the noise contact area, enhance the sound absorption effect, and achieve further reduction of noise. This design makes the noise-reducing air box 2 no longer just an exhaust channel, but a core component with both secondary heat dissipation and noise reduction functions, solving the problem of the single function of existing air boxes and comprehensively improving the performance of the equipment.

[0024] refer to Figure 3 The inner wall of the air intake pipe 5 is provided with multiple noise reduction grooves 14 that are evenly distributed in a ring.

[0025] As a technical optimization of this utility model, by setting an annularly distributed noise-reducing groove 14 on the inner wall of the air intake pipe 5, noise can be controlled at the initial stage of airflow entering the equipment. When the external airflow enters the air intake pipe 5, it will carry some environmental noise and noise generated by the fan operation. The noise-reducing groove 14 can change the direction of noise propagation, causing the noise to be continuously reflected and interfered within the groove, thereby canceling out the noise intensity through energy and achieving initial noise reduction.

[0026] refer to Figure 3 The base layer 6 is made of stainless steel, the first sound-absorbing layer 7 is made of open-cell polyurethane foam, the second sound-absorbing layer 8 is made of centrifugal glass wool, and the sound insulation layer 9 is made of damping sound insulation board.

[0027] As a technical optimization of this utility model, the base layer 6 is made of stainless steel, which has high strength and corrosion resistance, and can withstand the vibration of the equipment during operation and the influence of the external environment. This ensures the long-term stability of the structure of the noise reduction cover 3, the noise reduction air box 2, and the air intake pipe 5, and avoids the failure of the overall structure due to damage to the base layer 6. The first sound-absorbing layer 7 is made of open-cell polyurethane foam, whose rich pores can efficiently absorb mid-to-high frequency noise, and its lightweight texture will not increase the burden on the equipment. The second sound-absorbing layer 8 is made of centrifugal glass wool, which has good high-temperature resistance, is suitable for the heat dissipation environment inside the equipment, and can supplement the absorption of low-frequency noise, complementing the first sound-absorbing layer 7 and covering a wider range of noise frequencies. The sound insulation layer 9 uses a damping sound insulation board, which can effectively block the attenuated noise from propagating outward and prevent noise leakage. The scientific material combination allows the functions of the multi-layer structure to be fully utilized, ensuring that the equipment maintains a stable noise reduction and heat dissipation effect for a long time, and improving its reliability and durability.

[0028] The working principle and usage process of this utility model are as follows: During use, according to the requirements of the solution to be treated, connect the corresponding feed pipe to the feed end of the emulsifying pump body 1 and the discharge pipe to the discharge end of the emulsifying pump body 1. During the connection process, it is necessary to ensure that the pipe interface is well sealed to prevent solution leakage. Then, turn on the power supply of the equipment. At this time, first start the fan fixed by the bracket inside the air inlet pipe 5 and let the fan start running. Observe whether the airflow can smoothly enter the noise reduction hood 3 from the air inlet pipe 5, and then enter the noise reduction hood 2 through the opening 4 at the bottom of the noise reduction hood 3 that connects to the noise reduction hood 2. Finally, it is discharged from the air outlet of the noise reduction hood 2. After the fan runs stably and forms a stable heat dissipation airflow, start the motor of the emulsifying pump body 1. When the motor is running, it is located inside the noise reduction hood 3. The heat generated will be absorbed by the airflow driven by the fan. After the airflow carries the heat into the noise reduction hood 2, it is guided by the noise reduction frame 12 and the noise reduction wave plate 13 inside the noise reduction hood 2, and then discharged outside the equipment.

[0029] During the process of processing the solution, it is necessary to continuously monitor the operating status of the equipment and listen to the noise level during operation. Through the synergistic effect of the noise reduction cover 3, the noise reduction air box 2, the base layer 6 of the air inlet pipe 5, the first sound absorption layer 7, the second sound absorption layer 8 and the sound insulation layer 9, as well as the noise reduction perforated plate 11, the noise reduction frame 12, the noise reduction corrugated plate 13 and the noise reduction groove 14, the noise can be effectively controlled. If it is found that the air intake of the air inlet pipe 5 is reduced or the air outlet of the noise reduction air box 2 is not smooth during operation, the impurities on the surface of the dustproof net 10 can be cleaned after the equipment is stopped.

[0030] This invention employs a noise-reducing fan box 2 fixed at the bottom of the emulsifying pump body 1 and a noise-reducing cover 3 fixed at the top, with the two connected via a passage 4. Simultaneously, fans are mounted on brackets within the air inlet pipes 5 on both sides of the noise-reducing cover 3, constructing a complete heat dissipation system. When the fans operate, they drive airflow from the air inlet pipes 5 into the noise-reducing cover 3. Inside the cover, the airflow contacts the motor of the emulsifying pump body 1, absorbs heat, and then enters the noise-reducing fan box 2 through the passage 4 before finally being discharged. This effectively solves the problem of poor heat dissipation and overheating caused by the difficulty in timely heat dissipation in existing emulsifying pumps. Furthermore, the air inlet pipes 5, the noise-reducing cover 3, and the noise-reducing fan box 2 all adopt a multi-layered structure design. The base layer 6 serves as the foundation to ensure structural stability, the first sound-absorbing layer 7 and the second sound-absorbing layer 8 absorb the noise generated by the motor operation layer by layer, and the outer sound insulation layer 9 blocks the outward transmission of noise. This completely solves the problem of existing emulsifying pumps lacking a noise-reducing structure and causing noise to affect users, significantly improving the stability of equipment operation and user comfort.
