Description

Technical Field

[0001] This application relates to the technical field of paint and wax processing equipment, and in particular to a paint and wax impurity separation and treatment device. Background Technology

[0002] Lacquer wax is a high-value-added waxy material extracted and refined from natural lacquer, widely used in wood finishing, craft protection, leather polishing, and industrial anti-corrosion. During the production and processing of lacquer wax, the raw materials often contain solid impurities such as bark chips, wood scraps, and dust particles. To improve the purity of the lacquer wax and ensure product quality and performance, production lines typically require dedicated impurity separation equipment for pre-treatment and filtration of the lacquer wax materials. As the industry expands, market demands for both product purity and equipment efficiency are increasing, prompting impurity separation devices to continuously evolve towards higher efficiency and easier maintenance.

[0003] Currently used paint and wax impurity treatment devices typically employ a multi-stage cylindrical cavity structure, with filter components positioned between each stage and equipped with a stirring system to promote uniform material flow within the cavity. To enhance filtration efficiency, the filter components are usually fixed between the cylinders and operate in conjunction with the internal stirring system. In many devices, the stirring structure extends vertically through the filtration area, allowing the material to be stirred while simultaneously filtering impurities. Due to the structural need to coordinate the positional matching and coordinated movement between the filter components and the stirring components, existing devices generally adopt a relatively integrated and compact one-piece structure in their design.

[0004] However, due to the interlocking relationship between the filter assembly and the agitation structure, when the filter assembly becomes clogged, worn, or needs replacement, it is often impossible to disassemble it directly. The agitation structure, which is interconnected with it, must first be completely removed, and the device must be disassembled layer by layer. This disassembly and assembly process is cumbersome and complex, severely impacting actual maintenance efficiency and equipment usability. Therefore, how to ensure the proper coordination of filtration and agitation functions while providing the filter assembly with good disassembly and replacement convenience has become a critical technical challenge that urgently needs to be overcome in the design of current paint and wax impurity treatment devices. Utility Model Content

[0005] This application provides a paint and wax impurity separation and treatment device to solve the problem that the filter components of existing paint and wax impurity treatment devices are difficult to disassemble and replace quickly.

[0006] This application provides a paint and wax impurity separation and treatment device, including a mounting base, a stirring drive assembly, a separation cylinder assembly, a discharge assembly, a rubber tension spring, and a collection assembly;

[0007] The mounting base is provided with a support frame for mounting the separation cylinder assembly. The separation cylinder assembly is connected to the support frame and can rotate and stir the internal paint wax material under the stirring action of the stirring drive assembly. Four rubber tension springs are also provided between the side wall of the support frame and the four corners of the lower part of the mounting base. The stirring drive assembly is set on the mounting base and connected to a stirring shaft extending vertically into the interior of the separation cylinder assembly. The separation cylinder assembly consists of three layers of cylinders stacked one on top of the other. Two separation screens are provided between each layer of cylinders inside the separation cylinder assembly for multi-layer filtration of impurities in the paint wax material. The middle of the separation screen is provided with a raised cylindrical channel that allows the stirring shaft to pass through. Stirring blades for stirring the paint wax accumulated on the separation screens are detachably connected to the stirring shaft. The discharge assembly includes a wax discharge port provided on the side wall of the bottom cylinder and a impurity discharge port provided on the side walls of the upper two layers of cylinders. A collection assembly for receiving the impurity-removed paint wax is provided at the wax discharge port.

[0008] In one optional embodiment, the cylinders are connected by clamps, each clamp being independently openable. The top of the separating cylinder assembly is provided with a cylinder cover, which has an openable and closable feeding port. The cylinder cover is also connected to the top cylinder of the separating cylinder assembly by clamps, and the bottom end of the bottom cylinder is a closed bottom plate.

[0009] In one optional embodiment, the lower part of the inner wall of the upper two layers of the separation cylinder assembly is provided with an annular mounting plate for placing the separation screen. The separation screen and the annular mounting plate are also connected by bolts. The stirring shaft is a multi-segment structure, which is composed of multiple stirring shaft segments connected in sequence along the vertical direction. A detachable sleeve is provided between any two adjacent stirring shaft segments.

[0010] In one optional embodiment, three sets of stirring blades are arranged axially on the stirring shaft. The arrangement of the three sets of stirring blades on the stirring shaft corresponds to the internal regions of the three layers of the cylinder, wherein the stirring blades located in the upper two layers of the cylinder are located above the corresponding separation screen, and the stirring blades located in the bottom layer of the cylinder are located above the bottom plate of the bottom layer of the cylinder.

[0011] In one optional embodiment, a ventilation cover is also provided on the outer wall of the cylinder.

[0012] In one optional embodiment, the collection assembly includes a flexible corrugated pipe and a wax storage tank connected to the lower end of the flexible corrugated pipe, the upper end of the flexible corrugated pipe being connected to the wax discharge port.

[0013] In one optional embodiment, the paint and wax storage tank is provided with a liquid level observation window and a drain valve. The liquid level observation window is a vertically transparent structure, and the drain valve is located at the bottom side of the paint and wax storage tank.

[0014] In one optional embodiment, the stirring drive assembly includes a motor and a belt drive mechanism. The motor is vertically fixed on the mounting base, and the output shaft of the motor is connected to the stirring shaft through the belt drive mechanism.

[0015] In one alternative implementation, the mesh size of the two separating screens satisfies the requirement that the mesh diameter of the upper screen is larger than that of the lower screen.

[0016] Compared with the prior art, this application has the following beneficial effects:

[0017] 1. This application provides a paint and wax impurity separation and treatment device, wherein the separation cylinder assembly consists of three stacked cylinders, with separation screens installed between each layer. Each screen has a cylindrical channel in the middle for a stirring shaft to pass through. The stirring shaft, through the installation of stirring blades, positions the stirring blades above the screen. This structure forms a two-stage filtration path in the vertical direction, allowing the paint and wax material to pass through the two separation screens sequentially from top to bottom during stirring, gradually completing the filtration. Compared to a single-layer structure, this stacked layout enhances the ability to classify and intercept impurities during the stirring and flow process, expanding the effective screen surface and increasing the filtration coverage, thereby helping to improve impurity separation efficiency and the purity of the paint and wax.

[0018] 2. This application incorporates four rubber tension springs between the support frame and the mounting base, employing a flexible support method to buffer vibrations during equipment operation. Mechanical disturbances generated during the operation of the stirring drive assembly are dispersed and attenuated by the rubber tension springs, preventing direct impact on the cylinder. This elastic connection structure helps reduce structural fatigue and the probability of loosening during operation. Furthermore, this design is well-suited for scenarios with frequent load fluctuations or requiring long-term continuous operation, enhancing the equipment's operational stability and structural durability.

[0019] 3. The separating screen of this application has a cylindrical channel in the middle for the moving passage of the stirring shaft. The stirring blades are detachably connected to the stirring shaft and are correspondingly positioned above the separating screen to directly agitate the paint and wax materials. This structure allows for a non-fixed interlocking relationship between the stirring shaft and the separating screen. While maintaining the stirring function, the stirring shaft no longer serves as an attachment structure for the separating screen, avoiding constraints during disassembly. When cleaning or replacing the screen, the user only needs to remove the stirring blades to quickly disassemble the upper two layers of the separating cylinder assembly for cleaning or replacing the separating screen. The entire process does not require removing the stirring shaft as a whole, greatly simplifying the operation. Attached Figure Description

[0032] Please see Figures 1-5 , Figure 1This is a schematic diagram of the structure of a paint and wax impurity separation and treatment device provided in an embodiment of this application; Figure 2 This is a schematic diagram from another perspective of the paint and wax impurity separation and treatment apparatus provided in one embodiment of this application; Figure 3 A schematic diagram of the paint and wax impurity separation and treatment device provided in an embodiment of this application after removing the cylinder cover; Figure 4 This is a schematic diagram of a separating screen on a cylinder according to an embodiment of this application; Figure 5 This is a schematic diagram of the stirring blades on the stirring shaft provided in an embodiment of this application.

[0033] like Figures 1-5 As shown in the figure, this application provides a paint and wax impurity separation and treatment device, including a mounting base 100, a stirring drive assembly 200, a separation cylinder assembly 300, a discharge assembly 400, a rubber tension spring 600, and a collection assembly 500.

[0034] The mounting base 100 is equipped with a support frame 110 for mounting the separation cylinder assembly 300. The separation cylinder assembly 300 is connected to the support frame 110 and can rotate and stir the internal paint wax material under the stirring action of the stirring drive assembly 200. Four rubber tension springs 600 are also provided between the side wall of the support frame 110 and the four corners of the lower part of the mounting base 100. The stirring drive assembly 200 is mounted on the mounting base 100 and connected to a stirring shaft 700 extending vertically into the interior of the separation cylinder assembly 300. The separation cylinder assembly 300 is composed of three cylinders 310 stacked one on top of the other. The body assembly 300 contains two separation screens 320 between the layers of cylinders 310 for multi-layer filtration of impurities in the paint wax material. Each separation screen 320 has a raised cylindrical channel 321 in the center, allowing the stirring shaft 700 to pass through. The stirring shaft 700 is detachably connected to stirring blades 710 for agitating the paint wax accumulated on the separation screens 320. The discharge assembly 400 includes a wax discharge port 410 on the side wall of the bottom cylinder 310 and impurity discharge ports 420 on the side walls of the upper two cylinders 310. A collection assembly 500 is provided at the wax discharge port 410 to receive the purified paint wax. Optionally, the mounting base 100 has a funnel-shaped structure, with a flat base at the bottom and a tapered transition section at the top, and is welded or screwed to the support frame 110. The support frame 110 is a cylindrical frame with limiting reinforcing ribs along its inner circumference to provide a vertically upward mounting support surface. The support frame 110 has an upward opening, and its inner circumference directly supports the bottom edge of the separation cylinder assembly 300 and fixes the separation cylinder assembly 300, forming an upper-bearing fixed installation structure.

[0035] In this embodiment, the separation cylinder assembly 300 consists of three stacked cylinders 310, with separation screens 320 between each layer. Each screen 320 has a cylindrical channel 321 in the center for the agitator shaft 700 to pass through. The agitator shaft 700, through the installation of agitator blades 710, positions the agitator blades 710 above the screen. This structure forms a two-stage filtration path in the vertical direction, allowing the paint / wax material to pass through the two separation screens 320 sequentially from top to bottom during agitation, gradually completing the filtration. Compared to a single-layer structure, this stacked layout enhances the ability to classify and intercept impurities during agitation and flow, expanding the effective screen surface and increasing the filtration coverage, thereby helping to improve impurity separation efficiency and the purity of the paint / wax.

[0036] Furthermore, in this embodiment, four rubber tension springs 600 are installed between the support frame 110 and the mounting base 100, employing a flexible support method to buffer vibrations during equipment operation. Mechanical disturbances generated when the stirring drive assembly 200 operates can be dispersed and attenuated by the rubber tension springs, preventing direct impact on the cylinder 310. This elastic connection structure helps reduce structural fatigue and the probability of loosening during operation. Moreover, this design is well-suited for scenarios with frequent load fluctuations or requiring long-term continuous operation, enhancing the equipment's operational stability and structural durability.

[0037] In this embodiment, a cylindrical channel 321 is provided in the middle of the separating screen 320 for the moving passage of the stirring shaft 700. The stirring blades 710 are detachably connected to the stirring shaft and are correspondingly positioned above the separating screen 320 to directly agitate the paint and wax materials. This structure allows the stirring shaft 700 and the separating screen 320 to form a non-fixed interlocking relationship. While maintaining the stirring function, the stirring shaft 700 no longer serves as an attachment structure for the installation of the separating screen 320, avoiding any constraints during disassembly. When cleaning or replacing the screen, the user only needs to remove the stirring blades 710 to quickly disassemble the upper two layers of the cylinder 310 of the separating cylinder assembly 300 for cleaning or replacing the separating screen 320 on the cylinder 310. The entire process does not require the stirring shaft to be completely removed, greatly simplifying the operation.

[0038] Compared to the existing technology where the filter components and stirring structure are interlocked and interdependent, this embodiment achieves flexible cooperation between the stirring and filtering components through structural design. This not only preserves their ability to work together but also provides users with a simpler and faster disassembly and assembly path when the separation screen 320 becomes clogged, worn, or needs replacement. While fulfilling both filtration and stirring functions, the overall structure effectively overcomes the difficulties in screen disassembly and maintenance caused by the through-type stirring shaft structure in traditional equipment, significantly improving the maintenance efficiency and operational flexibility of the equipment.

[0039] It should be noted that the structure in which the stirring shaft 700 vertically passes through and enters the separation cylinder assembly 300 involves the issue of ensuring continuous rotation of the stirring shaft during operation while preventing material leakage along the shaft hole. This type of structure is conventional technology in equipment such as stirred containers, filter kettles, and reaction kettles, and is typically achieved by using a mechanical seal assembly to seal the rotating shaft. For example, a sealing cavity can be set at the insertion and rotational connection position of the stirring shaft 700, containing components such as a sealing bushing, elastic sealing ring, sealing gasket, or end face seal. Through axial or radial limiting cooperation, the rotational gap is effectively sealed, thereby preventing the leakage of internal waxy materials along the shaft hole without affecting the normal rotation of the stirring shaft 700. For applications requiring higher sealing performance, a double-end face mechanical seal can be selected, supplemented by a lubrication and cooling device to further improve the sealing effect. Since this type of sealing structure has been maturely applied in many industrial devices and has high reliability, it does not need to be elaborated upon again in this application.

[0040] In some embodiments, the cylinders 310 are connected by clamps 311, each clamp 311 can be opened independently, the top of the separating cylinder assembly 300 is provided with a cylinder cover 800, the cylinder cover 800 is provided with an openable and closable feeding port 810, the cylinder cover 800 is also connected to the top cylinder 310 of the separating cylinder assembly 300 by clamps 311, and the bottom end of the bottom cylinder 310 is a closed bottom plate.

[0041] In this embodiment, the cylinders 310 are connected by clamps 311, each of which can be opened independently. Compared with traditional bolt or welding methods, this connection method offers greater flexibility and efficiency in assembly and disassembly. During maintenance, the operator only needs to loosen the clamps 311 to quickly separate adjacent cylinders 310 without the need for additional tools or a complete disassembly device. This structure facilitates quick operation when replacing the separating screen 320 or cleaning the interior of the cylinders 310, reducing maintenance time and workload to some extent, and also contributing to improved equipment operation continuity and maintenance response speed.

[0042] In addition, a cylinder cover 800 is installed on the top of the separation cylinder assembly 300. This cylinder cover 800 has an openable and closable feeding port 810. The cylinder cover 800 is also connected to the uppermost cylinder 310 via a clamp 311, forming a relatively complete top-closed structure. During operation, the cylinder cover 800 serves to block foreign objects, reduce odor diffusion, and lower the risk of secondary pollution. The feeding port 810 facilitates material feeding while the equipment is running, avoiding problems such as paint and wax splattering caused by opening the entire cylinder cover.

[0043] Furthermore, in this embodiment, the bottom of the bottom cylinder 310 is a closed bottom plate, which, combined with the wax discharge port 410 and the collection component 500, forms a centralized discharge path for the purified paint wax. After being filtered through multiple layers, the paint wax material can naturally settle to the bottom area for easy and unified discharge. This closed bottom design reduces material residue and leakage, and also improves the cleanliness and controllability of the discharge process. In addition, the upper layer's openable and closable connection, achieved through the clamp 311, gives the separation cylinder component 300 excellent ease of layered disassembly and assembly, thus achieving a structural performance that integrates rapid disassembly and directional discharge. This better meets the needs of frequent use and maintenance in industrial settings and helps improve the overall reliability and adaptability of the equipment.

[0044] It should be noted that the various cylinder layers 310 are connected by openable clamps 311, facilitating disassembly between layers during maintenance or replacement of the screen 320. Furthermore, the overall design meets the equipment's operational requirements in terms of spatial arrangement and force transmission, ensuring that loose connections or structural stress concentration will not affect its use. Under normal operating conditions, simply setting the appropriate rotation speed and feed rate according to process requirements is sufficient to stably complete the two-stage filtration and impurity removal process for paint and wax materials.

[0045] In some embodiments, the lower part of the inner wall of the upper two layers of the cylinder 310 of the separation cylinder assembly 300 is provided with an annular mounting plate 312 for placing the separation screen 320. The separation screen 320 and the annular mounting plate 312 are also connected by bolts. The stirring shaft 700 has a multi-segment structure and is composed of multiple stirring shaft segments 701 connected in sequence along the vertical direction. A sleeve 702 is provided between any two adjacent stirring shaft segments 701.

[0046] In the above embodiment, an annular mounting plate 312 for mounting the separation screen 320 is added to the lower part of the inner wall of the two layers of cylinders 310 above the separation cylinder assembly 300. This structure provides a relatively stable support platform for the screen 320 and has a good installation and positioning function. Moreover, the separation screen 320 is further connected to the annular mounting plate 312 with bolts. This detachable fastening method takes into account both firmness and operability. When maintaining or replacing the screen, the operator only needs to loosen the bolts to remove the screen individually, making the disassembly and assembly of the separation screen 320 more efficient. It is suitable for industrial applications that require periodic maintenance or frequent cleaning. In addition, the setting of the annular mounting plate 312 can reduce the shaking, sagging or edge warping of the screen during the stirring process, thereby helping to improve the overall operational stability of the filtration structure under the stirring conditions of high viscosity materials, and providing a reliable foundation for the purification effect of paint and wax from a structural perspective.

[0047] Furthermore, in this embodiment, the stirring shaft 700 adopts a multi-segment design, consisting of multiple stirring shaft segments 701, with adjacent segments connected by detachable sleeves 702. This segmented assembly method is more adaptable than the traditional one-piece long shaft structure, especially in screen replacement or partial disassembly of the separation cylinder. Operators can disassemble the stirring shaft segment by segment as needed without having to pull it out entirely or interfere with the bottom stirring drive assembly 200, simplifying the operation process. This structure makes the maintenance of the device more convenient.

[0048] In some embodiments, three sets of stirring blades 710 are axially spaced on the stirring shaft 700. The arrangement positions of the three sets of stirring blades 710 on the stirring shaft 700 correspond to the internal regions of the three-layer cylinder 310, and the stirring blades 710 located inside the upper two layers of cylinder 310 are located above the corresponding separation screen 320, while the stirring blades 710 inside the bottom cylinder 310 are located above the bottom plate of the bottom cylinder 310.

[0049] In this embodiment, the stirring shaft 700 is provided with three sets of stirring blades 710 spaced apart along the axial direction. The axial positions of the three sets of stirring blades 710 correspond sequentially to the internal spaces of the three layers of cylinders 310 in the separation cylinder assembly 300, ensuring an appropriate axial spacing between the three sets of stirring blades 710. This arrangement allows the paint and wax material inside each layer of cylinder 310 to be effectively stirred in its corresponding area, effectively avoiding the problem of stirring blind spots in certain layers due to concentrated blade arrangement. By distributing the stirring power to each layer, this embodiment ensures that the paint and wax material receives relatively uniform disturbance in the upper, middle, and lower regions. This allows for more thorough contact and filtration when flowing through the separation screen 320 arranged between the cylinders 310, contributing to improved uniformity and continuity of the impurity removal process.

[0050] Furthermore, the three-blade configuration facilitates subsequent equipment maintenance. Since each set of agitator blades 710 is detachable, when a screen needs replacement or internal cleaning is required on a particular layer, the agitator blades 710 can be partially disassembled, reducing the overall disassembly and reassembly workload. This rationally distributed and flexible structural design helps the equipment maintain good operability and maintainability during long-term operation.

[0051] In this embodiment, the stirring blade 710 is assembled with the stirring shaft 700 using a detachable connection, which also facilitates individual replacement during maintenance or cleaning, avoiding the need to replace the entire stirring shaft due to blade wear. The detachable connection allows for flexible selection of various conventional structures depending on the specific application scenario, such as threaded connections, pin insertion, and slot snap-fit ​​connections, all of which are well-known and mature connection methods in the art.

[0052] Optionally, in this embodiment, a compact and easy-to-operate detachable method is provided as a preferred example, namely, rapid assembly is achieved through an integrated structure of the connecting ring and the blade. Specifically, the stirring blade 710 includes a connecting ring with internal threads, which is firmly fixed to the outer surface of the stirring shaft 700 by threaded connection. Stirring blades connected by connecting rods are integrally provided on the outer edge of the connecting ring, and the blades can be symmetrically distributed to achieve effective material disturbance. The operator only needs to rotate the connecting ring to quickly disassemble and install the stirring blade 710, greatly improving operating efficiency and reducing maintenance difficulty. This structure, combined with the multi-segment design of the stirring shaft 700, further enhances the overall maintainability and application flexibility of the device.

[0053] In some embodiments, a ventilation cover 313 is also provided on the outer wall of the cylinder 310.

[0054] In this embodiment, a ventilation cover 313 is provided on the outer wall of the cylinder 310, creating an air channel between the interior of the separation cylinder assembly 300 and the external environment. This structure facilitates the timely removal of moisture and volatile gases generated inside the cylinder 310 due to stirring or temperature changes during stirring and filtration. Especially when processing high-viscosity paint and wax materials, the ventilation design effectively improves the problem of air stagnation within the cavity, guiding the sinking and flow of materials, thus providing a smoother medium flow environment for subsequent filtration. In practical use, the ventilation cover 313 generally adopts a hinged structure design, which can be manually opened during use for rapid ventilation. During equipment operation, if it is necessary to improve exhaust efficiency, the ventilation cover 313 can be opened appropriately to allow for faster exchange of hot and humid air inside with the outside, thereby maintaining the temperature and humidity balance inside the cylinder. In daily operation, the operator can also adjust the opening frequency and duration of the ventilation cover 313 according to different material processing requirements to achieve better ventilation management.

[0055] In some embodiments, the collecting component 500 includes a flexible corrugated pipe 510 and a wax storage tank 520 connected to the lower end of the flexible corrugated pipe 510, with the upper end of the flexible corrugated pipe 510 connected to the wax discharge port 410.

[0056] In this embodiment, the collection component 500 connects the wax discharge port 410 to the paint wax storage tank 520 via a flexible corrugated pipe 510, forming a compact and flexible paint wax guiding and collection system. The flexible corrugated pipe 510 has a certain degree of bending and expansion capacity, which can alleviate connection stress caused by vibration during equipment operation, reducing the probability of loosening or damage at the connection points, making it more reliable. Furthermore, the use of the flexible corrugated pipe 510 provides high flexibility in the layout of the wax discharge path; the angle of the flexible corrugated pipe 510 can be adjusted according to the installation environment, better adapting to actual needs. During use, the paint wax is guided smoothly into the paint wax storage tank 520 located below through the corrugated pipe 510, achieving directional collection in a closed environment. This collection method reduces the risk of material leakage, helps control on-site pollution, and improves operational cleanliness. At the same time, the closed transmission also reduces the time the material is exposed to air, which has a positive impact on quality control in subsequent processing.

[0057] In some embodiments, the paint and wax storage tank 520 is provided with a liquid level observation window 521 and a drain valve 522. The liquid level observation window 521 is a vertically transparent structure, and the drain valve 522 is located at the bottom side of the paint and wax storage tank 520.

[0058] In this embodiment, by providing a liquid level observation window 521 and a drain valve 522 on the paint wax storage tank 520, the visibility and operational flexibility of the collection component 500 during use are further improved. The liquid level observation window 521 adopts a vertically arranged transparent window structure, which can directly display the liquid level of the paint wax in the paint wax storage tank 520, allowing the operator to understand the collection status at any time during operation and make timely adjustments. This visualization design avoids the operation of frequently opening the tank lid for inspection, reduces the risk of foreign objects entering or paint wax being contaminated, and helps maintain the cleanliness of the tank environment. The drain valve 522 is located on the side bottom of the storage tank 520, allowing the paint wax to be discharged smoothly without tilting the entire tank, making the operation more convenient.

[0059] In some embodiments, the stirring drive assembly 200 includes a motor 210 and a belt drive mechanism 220. The motor 210 is vertically fixed on the mounting base 100, and the output shaft of the motor 210 is connected to the stirring shaft 700 via the belt drive mechanism 220. Optionally, the belt drive mechanism 220 specifically includes a main pulley 221, a driven pulley 222, and a drive belt 223 surrounding it. The main pulley 221 is fixedly connected to the output shaft end of the motor 210, and the driven pulley 222 is installed at the lower end of the stirring shaft 700. The drive belt 223 is made of elastic material and has a certain buffering and vibration absorption capacity, which can effectively alleviate the transmission of impact force when the motor starts or the load fluctuates. In actual use, the rotational speed of the stirring shaft 700 can also be adapted and adjusted by designing the diameter ratio of the main pulley 221 and the driven pulley 222. This belt drive structure is compact and easy to disassemble and replace, which can improve the operational stability and maintenance convenience of the stirring drive assembly 200.

[0060] In this embodiment, the stirring drive assembly 200 adopts a structure in which a motor 210 and a belt drive mechanism 220 cooperate. The motor 210 is vertically fixed on the mounting base 100, driving the stirring shaft 700 to output rotational power in the vertical direction. This arrangement enables the stirring shaft 700 to maintain a good vertical posture and rotational stability inside the separation cylinder assembly 300, reducing operational sway and improving the balance performance of the stirring process.

[0061] As an intermediate component for power transmission, the belt drive mechanism 220 possesses a certain degree of flexibility. During operation, it can absorb some mechanical shocks and high-frequency vibrations, mitigating the inertial load during motor start-up and shutdown, thus playing a positive role in extending the service life of the motor 210 and the stirring shaft 700. In terms of maintenance, the belt drive structure is also relatively easy to disassemble and replace.

[0062] In some embodiments, the mesh size of the two separating screens 320 meets the requirement that the mesh diameter of the upper screen is larger than that of the lower screen.

[0063] In traditional paint and wax impurity treatment equipment, technicians in the field rarely use multi-layer filtration structures, mainly because paint and wax materials have high viscosity and adhesiveness, which easily causes filter layer blockage during stirring or sieving. If a multi-stage screen stacking structure is used, insufficient stirring or an unreasonable screen channel design can easily lead to upper-layer impurity deposition, affecting the unobstructed flow of lower-layer channels, thus reducing the overall filtration efficiency. Therefore, most existing treatment equipment uses only a single-layer filtration method to reduce structural complexity and maintenance difficulty. However, in this embodiment, by setting a three-layer cylinder 310 and configuring two separating screens 320 between two of the layers, a two-stage filtration structure is achieved, which helps to disperse the impurity load and improve filtration accuracy. The two separating screens 320 have sieve apertures that gradually decrease in size from top to bottom. The first screen is used to initially intercept larger particulate impurities, with an aperture size of 2.0-3.0 mm. The second screen is used to further remove finer particles, with an aperture size of 0.5-1.0 mm, thus achieving layer-by-layer separation of impurities of different particle sizes in the paint and wax. This screen configuration design helps to slow down the clogging rate of the lower screen and, in conjunction with the layered stirring blades 710 on the stirring shaft 700, maintains continuous agitation and flow of the material, preventing impurities from accumulating and thus maintaining smooth filtration and stable efficiency. Through this structural matching, multi-stage filtration becomes engineering feasible for processing highly viscous paint and wax materials.

[0064] In this embodiment, the use of two separating screens avoids the problem of insufficient filtration efficiency in a single layer, while also avoiding the structural complexity and cleaning difficulties associated with multi-layer structures. The first layer is used for coarse filtration, and the second layer for fine filtration, with clear layers and complementary functions. Too many layers would increase resistance and maintenance burden, while too few would make effective grading difficult. It is precisely this two-layer design that achieves a balance between filtration efficiency and operability, with just the right number of layers.

[0065] Although multi-stage filtration has been applied in other fluid handling applications, its direct application in the field of high-viscosity paints and waxes cannot be simply compared. Paints and waxes themselves are characterized by heat sensitivity, easy coagulation, and diverse types of impurities, which places comprehensive requirements on the screen layout, stirring method, and screen mesh ratio.

[0066] Optionally, in some embodiments, the bottom of the mounting base 100 is provided with an adjustable height support 120, the height of which can be adjusted by a height adjustment screw.

[0067] The usage process of the paint and wax impurity separation and treatment device in this embodiment is as follows:

[0068] In this embodiment, the operation of the paint wax impurity separation and treatment device begins with the feeding stage. The operator can feed the paint wax raw material to be processed into the internal space of the separation cylinder assembly 300 through the feeding port 810 on the cylinder cover 800. The added paint wax raw material first falls onto the uppermost separation screen 320. Subsequently, the motor 210 on the mounting base 100 starts running, and transmits power to the stirring shaft 700 through the belt drive mechanism 220, causing the stirring shaft 700 and the stirring blades 710 on the stirring shaft 700 to rotate synchronously in each layer of the cylinder 310, thereby causing the paint wax material to form continuous disturbance inside the cylinder, causing the paint wax and the impurities entrained therein to separate into layers.

[0069] Under the action of the stirring blades 710, the paint wax material fully contacts the separation screens 320 distributed between each layer. Larger solid impurities in the material are effectively intercepted by the screen surface and gradually accumulate on the separation screens 320 of the upper two layers of the cylinder 310. As the stirring shaft 700 continuously drives the stirring blades to rotate, the impurities on the separation screens 320 move along the screen surface towards the side wall under the force of the stirring, and are finally discharged outside the cylinder through the discharge ports 420 set on the side walls of the two layers of cylinder. The paint wax material after sieving continues to flow to the lower layer and finally settles into the bottom cylinder.

[0070] The pure paint wax collected in the bottom cylinder 310 is discharged through the wax discharge port 410 on its side wall and then guided into the paint wax storage tank 520 below via the flexible corrugated pipe 510 for collection. Throughout the collection process, the liquid level observation window 521 can reflect the liquid level in the storage tank in real time, making it easy for the operator to monitor the amount of paint wax remaining. When the designated liquid level is reached, the paint wax can be discharged in an orderly manner by opening the drain valve 522 for subsequent processing or storage. At the same time, the ventilation cover 313 located on the outer wall of the cylinder allows for natural air exchange between the inside and outside of the cylinder, helping to maintain unobstructed internal flow during the operation of the device, reducing the impact of moisture accumulation on the screen permeability, and improving the overall filtration stability.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
