Description

Technical Field

[0001] This utility model relates to the field of cosmetic production equipment, specifically a filter device for the discharge pipe of an emulsifying pot. Background Technology

[0002] Cosmetic emulsions are stable dispersion systems composed of an aqueous phase (such as deionized water and moisturizers) and an oil phase (such as plant oils and silicone oils) mixed with emulsifiers, possessing moisturizing, nourishing, and repairing effects. Their production process requires a comprehensive consideration of stability, safety, and functionality, with core processes encompassing raw material processing, emulsification and mixing, cooling and maturation, filling, and quality inspection.

[0003] However, traditional emulsifying pots commonly suffer from residual solid impurities during the discharge stage, which severely impacts the quality and stability of the final product. In existing technologies, emulsifying pots lack effective filtration components after discharge, or the filtration structure is overly simplistic, often resulting in solid impurities remaining in the emulsified material after discharge. These impurities originate from incompletely dissolved components of the raw materials or from clumps formed during emulsification. These residual impurities not only affect the uniformity of the product's appearance and user experience but may also reduce product safety and shelf life. Therefore, a filtration device is needed between the emulsifying pot and the filling equipment.

[0004] Currently, most methods involve installing static filters at the outlet of the emulsifying pot. However, this method has significant drawbacks: on the one hand, a single-layer filter can only intercept particles of a specific size and cannot achieve multi-stage filtration; on the other hand, as impurities accumulate on the filter, the discharge resistance increases, and it may even become completely blocked, requiring frequent shutdowns for cleaning, which seriously affects production efficiency. Utility Model Content

[0005] To overcome some of the problems mentioned in the background above, a filtration device for the discharge pipe of an emulsifying pot is provided.

[0006] The technical solution adopted by this utility model is as follows: A filter device for the discharge pipe of an emulsifying pot, comprising a feeding unit, a rotary filter module and a discharge unit, wherein the feeding unit and the discharge unit are respectively disposed at both ends of the pipe, and the rotary filter module is disposed inside the pipe; The rotary filter module includes a rotary unit and a multi-stage filter unit. The rotary unit is located on one side of the feeding unit, and the multi-stage filter unit is located on one side of the discharging unit. The rotating unit includes multiple blades that rotate in response to the emulsion flow. The multi-stage filtration unit includes at least two layers of filter screens, with the pore size of each layer decreasing progressively along the emulsion flow direction.

[0007] Furthermore, the pipe is provided with a rotating bearing interface and a filter bearing interface at both ends, the rotating unit is connected to the rotating bearing interface, and the multi-stage filter unit is connected to the filter bearing interface.

[0008] Furthermore, the rotating unit also includes a bearing support unit, and the blade is disposed within the bearing support unit; The bearing support unit includes an inner ring, an outer ring, and a bearing. The blade is fixed between the inner ring and the outer ring. The bearing is connected to the outer wall of the outer ring and the bearing is connected to the inner wall of the rotating bearing interface.

[0009] Furthermore, the blades are provided with an inclination angle, which is configured to convert the flowing kinetic energy into rotational torque.

[0010] Furthermore, the multi-stage filtration unit also includes a limiting ring and a connecting ring. The limiting ring is connected to the inner wall of the pipe, and the connecting ring is disposed between two adjacent filter screens.

[0011] Furthermore, the feeding unit includes a feeding pipe, a feeding flange, and a stop block. The feeding pipe and the stop block are respectively disposed on both sides of the feeding flange. The feeding flange is fixedly connected to the pipe by bolts, and the stop block abuts against the side wall of the bearing.

[0012] Furthermore, the discharge unit includes a discharge pipe and a discharge flange. The discharge flange is fixedly connected to the pipe by bolts. The discharge pipe is used to output the emulsion processed by the multi-stage filtration unit.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The blades in the rotating unit rotate autonomously during the emulsion flow, further breaking down the emulsion. This dynamic rotation mechanism effectively prevents clogging during filtration and promotes uniform distribution of the material throughout the filtration space.

[0014] The filters in the multi-stage filtration unit are arranged and installed in sequence according to the flow direction of the emulsion, and the pore size of each layer of filter screens shows a distribution characteristic of gradually decreasing, thereby realizing a complete multi-stage filtration process from primary coarse filtration to final fine filtration, and improving the quality of the output emulsion.

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.

[0019] like Figures 1-5 As shown, in some embodiments, an emulsifying pot discharge pipe filtration device includes a feeding unit 1, a rotary filtration module, and a discharge unit 3. The feeding unit 1 serves as the initial inlet for the emulsified material, with one end connected to the emulsifying pot and the other end sealed to the left end of the pipe 2 via a flange connection. The discharge unit 3 serves as the final outlet for the filtered finished material, with one end also securely connected to the right end of the pipe 2 via a flange connection, and the other end connected to a filling device. A rotatable dynamic filtration module system is installed within the cylindrical internal cavity of the pipe 2.

[0020] Specifically, the rotary filtration module includes a rotary unit 4 and a multi-stage filtration unit 5. The rotary unit 4 is located near the feed unit 1, and its main function is to powerfully agitate and uniformly disperse the emulsion entering the pipe 2 as a pretreatment. The multi-stage filtration unit 5 is located near the discharge unit 3 and is specifically responsible for performing multi-level fine filtration of the pretreated emulsion. The two functional units work together to ensure the high efficiency and stability of the entire filtration process. The modular design of the multi-stage filtration unit 5 allows for quick disassembly and assembly of the equipment during cleaning and maintenance.

[0021] In terms of specific structure, the rotating unit 4 consists of three specially curved blades 43. These spirally arranged blades 43 will generate autonomous rotation during the emulsion flow process, further breaking up the emulsion. This dynamic rotation mechanism can effectively prevent the material from clogging during the filtration process, and can also promote the uniform distribution of the material in the entire filtration space.

[0022] The multi-stage filtration unit 5 adopts an advanced progressive gradient filtration design, including at least two layers of filter screens 51. These filter screens 51 are arranged and installed sequentially according to the flow direction of the emulsion, and the pore size 53 of each layer of filter screens 51 has a progressively decreasing distribution characteristic of 200μm, 100μm, etc., thereby realizing a complete multi-stage filtration process from primary coarse filtration to final fine filtration.

[0023] Furthermore, in some embodiments, the pipe 2 serves as the core conveying component of the entire filtration system, with a rotary bearing interface 21 and a filter bearing interface 22 at its two ends, respectively. The rotary bearing interface 21 is located at the material input end of the pipe 2 and is connected to the feeding unit 1. The filter bearing interface 22 is located at the material output end of the pipe 2 and is connected to the discharge unit 3.

[0024] The rotating unit 4 is installed inside the rotating bearing interface 21. The rotating unit 4 can rotate within the rotating bearing interface 21 to ensure that the emulsion can rotate stably during the conveying process and further agitate the emulsion.

[0025] Meanwhile, the multi-stage filtration unit 5 is set inside the filter carrier interface 22. The discharge unit 3 fixes the multi-stage filtration unit 5 inside the filter carrier interface 22. It is equipped with a sealing ring inside, which facilitates the later maintenance and replacement of the filter components.

[0026] Furthermore, in some embodiments, the rotating unit 4 also includes a shaft support unit to support the rotating unit 4. The impeller 43, as a key stirring element, is installed within the internal space of the bearing support unit. The impeller 43, as a key stirring element, is installed within the internal space of the bearing 41 support unit; this arrangement ensures both effective stirring and optimized overall structural compactness.

[0027] The bearing support unit includes an inner ring 44, an outer ring 42, and a bearing 41. The blade 43 is securely fixed to the annular space between the inner ring 44 and the outer ring 42 by welding or high-strength bolts. This double-fixing method ensures the stability of the blade 43 during rotation. The inner ring of the bearing 41 is interference-fitted with the outer wall of the outer ring 42, effectively preventing loosening. Simultaneously, the outer ring of the bearing 41 is reliably connected to the inner wall of the rotating bearing interface 21 through a precision fit, thereby ensuring the long-term stable operation of the entire rotating unit 4 and reducing vibration and noise.

[0028] Furthermore, in some embodiments, the impeller 43 is installed at a specific tilt angle, so that when material flows over the surface of the impeller 43, the kinetic energy generated by the fluid flow can be effectively converted into the torque required for the impeller 43 to rotate. This ingenious angle configuration not only improves energy conversion efficiency but also ensures the stability and uniformity of the stirring process, thereby significantly improving the overall performance of the filtration device.

[0029] Furthermore, in some embodiments, the multi-stage filtration unit 5 also includes a limiting ring 52 and a connecting ring 54. The limiting ring 52 serves as an axial positioning element, forming a secure connection with the inner wall of the pipe 2 through a snap-fit ​​mechanism, thereby achieving precise positioning of the filter screen 51 and preventing axial displacement of the multi-stage filtration unit 5 during use.

[0030] The connecting ring 54 is set between two adjacent filter screens 51, which not only provides mechanical support, but also effectively connects the filter screens 51 at each level.

[0031] Furthermore, in some embodiments, the feeding unit 1 includes a feeding pipe 11, a feeding flange 12, and a stop block 13, which together form a complete feeding system.

[0032] Specifically, the feed pipe 11 and the stop block 13 are respectively arranged on both sides of the feed flange 12, forming a stable structural arrangement. The feed flange 12 is fixedly connected to the pipe 2 by bolts to ensure the sealing and stability of the connection.

[0033] Of particular note is that the stop 13 forms a tight abutment with the side wall of the bearing 41. This design not only effectively prevents material leakage, but also provides support and positioning, thereby ensuring the stability and reliability of the entire rotating unit 4.

[0034] Furthermore, in some embodiments, the discharge unit 3 includes a discharge pipe 32 and a discharge flange 31. The discharge flange 31 is bolted to the pipe 2 to ensure the sealing and structural stability of the entire discharge system. The discharge pipe 32 is specifically designed to smoothly output the emulsion, after being finely processed by the multi-stage filtration unit 5, to the next process, ensuring the stability and consistency of product quality.

[0035] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
