Technical Field
[0001] This utility model relates to the field of chemical cleaning technology, and in particular to a polyester screen pickling and descaling cleaning bracket. Background Technology
[0002] In modern mineral processing operations, the polyurethane (or polyester) screen mesh of vibrating screens is crucial. However, in actual production circulating water systems, the screen mesh is easily accumulating stubborn dirt. The hazards are mainly manifested in the following aspects:
[0003] Decreased screening efficiency: Clogging of the screen mesh obstructs the passage of fine-grained materials, resulting in a significant drop in screening accuracy and efficiency.
[0004] Abnormal equipment operation: Scaling affects the normal vibration mode of the vibrating screen, increases the equipment load, and reduces operational stability.
[0005] Increased maintenance costs: To restore screening capacity, the screens need to be disassembled, cleaned, or replaced regularly, which is costly.
[0006] The current industry practice of using high-pressure water guns to clean surfaces on the ground or simple workbenches has problems:
[0007] Poor cleaning effect: It is difficult to completely remove stubborn dirt with strong adhesion and deep penetration, especially dirt inside and around the sieve holes.
[0008] Easily damages the screen: Extending the rinsing time or increasing the water pressure to remove dirt can easily cause the screen to break, stretch, or wear on the edges, shortening its service life.
[0009] Inconvenient to operate and inefficient: The screen is not easy to fix on the ground and is prone to displacement under high pressure water, resulting in uneven washing, increasing the complexity of operation and labor intensity. Utility Model Content

[0032] 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.
[0033] The purpose of this utility model is to provide a cleaning bracket for acid washing and descaling of polyester screens to solve the problems existing in the prior art. It has a simple structure, is easy to use, effectively removes stubborn scale from polyester screens, reduces damage to the screens, and effectively improves the convenience and efficiency of cleaning operations.
[0034] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0035] Example 1
[0036] This embodiment provides a polyester screen 3 acid pickling and descaling cleaning bracket, such as Figures 1-9 As shown, the system includes: a base 10, a steel pipe frame 1, at least one upper fixed hook 2, at least one lower movable hook 4, and an elastic tensioning mechanism. The steel pipe frame 1 is fixedly connected to the base 10. The upper fixed hook 2 is installed in the top area of the steel pipe frame 1 to hook onto the upper edge of the polyester screen 3. The lower movable hook 4 slides in the bottom area of the steel pipe frame 1 and hooks onto the lower edge of the polyester screen 3. One end of the elastic tensioning mechanism is connected to the base 10, and the other end is connected to the lower movable hook 4, so as to provide a continuous downward pulling force to the lower movable hook 4. This allows the lower movable hook 4 and the upper fixed hook 2 to work together to tighten the polyester screen 3. This overall structural design can reliably tighten the polyester screen 3, providing a stable and taut screen 3 condition for subsequent cleaning operations. The base 10 provides a stable support foundation for the entire support system, and the fixed steel pipe frame 1 and the upper and lower hooks allow the screen 3 to be accurately positioned. The continuous downward pulling force generated by the elastic tensioning mechanism can evenly tighten the polyester screen 3, ensuring that the screen 3 will not be loosened during the cleaning process and thus not affect the cleaning effect. This effectively improves the flushing efficiency and penetration of high-pressure water washing on dirt.
[0037] In a preferred embodiment, a guiding mechanism is further included. This guiding mechanism is positioned between the lower movable hook 4 and the elastic tensioning mechanism to guide the lower movable hook 4 to move along the extension direction of the polyester screen 3. The guiding mechanism ensures more precise and stable movement of the lower movable hook 4. It guarantees that the lower movable hook 4 moves along the extension direction of the polyester screen 3, making the tension applied to the screen 3 by the elastic tensioning mechanism more uniform and linear. This avoids uneven local stress on the screen 3 caused by deviations in the movement of the lower movable hook 4, further improving the stability and reliability of the screen 3's tension, thereby enhancing the uniformity and effectiveness of water flow in rinsing away dirt during the cleaning process.
[0038] In a preferred embodiment, the guiding mechanism includes a guide channel steel 5 and a guide rod 6. The guide channel steel 5 is fixed to the bottom crossbeam of the steel pipe frame 1. The guide channel steel 5 is provided with multiple guide holes 501. The top end of the guide rod 6 is fixedly connected to the lower movable hook 4, and the lower end of the guide rod 6 passes through the guide hole 501 and is connected to the elastic tensioning mechanism. This specific structural form of the guiding mechanism more clearly and effectively constrains and guides the movement of the lower movable hook 4. The fixed guide channel steel 5 and the guide rod 6 that cooperate with it, through the precise guiding effect of the guide hole 501, ensure that the guide rod 6 and the lower movable hook 4 connected to it can only make stable linear sliding in the vertical direction, eliminating the shaking and deviation of the lower movable hook 4 during the movement, greatly enhancing the stability and controllability of the overall structure, and also ensuring that the tension of the elastic tensioning mechanism can be accurately transmitted to the lower edge of the screen 3, realizing a stable and reliable tensioning function of the screen 3.
[0039] In a preferred embodiment, the elastic tensioning mechanism includes a tension spring 7. The upper end of the tension spring 7 is connected to the lower end of the guide rod 6, and the lower end of the tension spring 7 is connected to the base 10. As a key component of the elastic tensioning mechanism, the tension spring 7 provides continuous and stable tension due to its inherent characteristics. It connects the guide rod 6 and the base 10, and uses its own elastic restoring force to pull the guide rod 6 downward, thereby providing a continuous downward pull to the lower movable hook 4 connected to the guide rod 6. This stable tension can be adjusted according to the actual needs of the screen 3 and remains stable during long-term use, without significant fluctuations in tension due to usage frequency and time. This ensures that the screen 3 remains in a uniformly taut state throughout the cleaning process, which is beneficial for improving cleaning effect and efficiency.
[0040] In a preferred embodiment, multiple fixing rods 8 are further included. The fixing rods 8 are vertically fixed to the top surface of the base 10, and the top end of each fixing rod 8 is fixedly connected to the lower end of the corresponding tension spring 7. The multiple fixing rods 8 further enhance the stability and reliability of the connection to the lower end of the tension spring 7. The fixing rods 8, vertically connected to the top surface of the base 10, provide a stable support point for the tension spring 7, ensuring that the tension spring 7 maintains an accurate position during the application of tension, preventing displacement or shaking due to vibration, changes in tension, or other factors. This not only ensures that the tension spring 7 can stably provide tension to the lower movable hook 4, but also makes the entire elastic tensioning mechanism more robust, adaptable to different working conditions, and extends the service life of the entire cleaning bracket.
[0041] In a preferred embodiment, the top of the fixed rod 8 is provided with a lower hook hole 801, and the bottom of the guide rod 6 is provided with an upper hook hole 601. The top of the tension spring 7 is hooked to the upper hook hole 601, and the bottom of the tension spring 7 is hooked to the lower hook hole 801. This hook hole design enables quick assembly and disassembly between the tension spring 7, the guide rod 6, and the fixed rod 8. When the tension spring 7 needs to be replaced due to aging or damage, the operator does not need to use complicated tools; they can simply remove the spring from the hook hole to complete the disassembly. The installation of a new spring is also convenient, greatly shortening maintenance and replacement time, improving equipment maintenance efficiency, and reducing the labor intensity of maintenance work. At the same time, the hook hole connection method also allows the tension spring 7 to make slight angle adjustments during operation to a certain extent, avoiding damage caused by excessive twisting of the spring due to installation errors or uneven force, and extending the actual service life of the tension spring 7.
[0042] In a preferred embodiment, multiple supporting diagonal braces 9 are further included. The top end of each supporting diagonal brace 9 is fixedly connected to the steel pipe frame 1, and the bottom end of each supporting diagonal brace 9 is fixedly connected to the base 10. The inclusion of the supporting diagonal braces 9 significantly enhances the structural strength and stability of the entire cleaning support. The design, with one end connected to the steel pipe frame 1 and the other end connected to the base 10, forms a stable triangular support structure. This structure effectively disperses the stress generated by the steel pipe frame 1 when bearing the weight of the screen 3 and various external forces during the cleaning process, greatly improving the support's ability to resist risks such as tipping over and deformation. Even under prolonged operation or significant external impact, the entire support maintains good stability, providing a reliable operating platform for cleaning the polyester screen 3.
[0043] In a preferred embodiment, the steel pipe frame 1, upper fixed hook 2, lower movable hook 4, guide channel steel 5, guide rod 6, tension spring 7, supporting diagonal brace 9, and base 10 are made of corrosion-resistant metal materials. Using corrosion-resistant metal materials for each component effectively counteracts the corrosive effects of the pickling solution during the acid pickling and descaling process of the polyester screen 3. The cleaning support needs to be used long-term in an environment containing pickling solution. If the components are not corrosion-resistant, it will lead to damage, rust, and reduced structural strength. Using corrosion-resistant metal materials not only ensures that each component maintains stable performance under the corrosive effects of pickling solution, but also extends the service life of the entire cleaning support, reduces maintenance and replacement costs due to corrosion, and improves the reliability and economy of the equipment.
[0044] In a preferred embodiment, the screen 3 has an upper hook 301 at the top and a lower hook 302 at the bottom. The upper fixed hook 2 matches the shape of the upper hook 301, and the lower fixed hook matches the shape of the lower hook 302. Furthermore, the upper fixed hook 2 and the lower movable hook 4 are designed to adapt to and firmly clamp the edges of polyester screens 3 of different sizes. The matching upper and lower hooks of the screen 3 provide convenience and stability for the connection between the screen 3 and the cleaning support. The matching shape design ensures that the screen 3 can be accurately and firmly hung on the support, preventing it from falling off or loosening during the cleaning process, thus ensuring smooth cleaning. The upper fixed hook 2 and the lower movable hook 4 can adapt to the edges of polyester screens 3 of different sizes, greatly improving the versatility and applicability of the cleaning support. This allows the cleaning support to be used with various sizes of polyester screens 3, expanding its application range and increasing the equipment's value and economic benefits.
[0045] Example 2
[0046] This embodiment also provides a method for acid washing and descaling of polyester screen 3 using any of the above-mentioned polyester screen 3 acid washing and descaling cleaning brackets, including the following steps:
[0047] Preparation
[0048] Place the polyester screen 3 pickling and descaling cleaning bracket in a suitable operating area, ensuring that the base 10 is stably placed on the ground. The supporting diagonal braces 9 effectively enhance the overall stability of the bracket, enabling it to withstand various forces generated during subsequent operations. The structural design of the supporting diagonal braces 9 ensures the bracket remains stable under various external forces, providing a reliable foundation for subsequent operations.
[0049] Confirm that all components of the cleaning support are securely connected, especially the steel pipe frame 1, upper fixed hook 2, lower movable hook 4, guide channel steel 5, guide rod 6, tension spring 7, fixing rod 8, and the connection points between each component. These tight and secure connections ensure the support will not loosen during use, making the overall structure stable and reliable, and guaranteeing smooth subsequent operations. Inspect all components for damage or corrosion, especially those made of corrosion-resistant metal materials. Because the components are made of corrosion-resistant metal materials, their performance remains stable even in environments where they may come into contact with pickling solutions, ensuring that the support's performance is not affected during use.
[0050] Prepare the polyester screen 3 to be cleaned, and check whether the upper hook 301 and lower hook 302 of the screen 3 are intact.
[0051] Install polyester screen 3
[0052] Accurately attach the upper hook 301 on the top of the polyester screen 3 to the upper fixed hook 2 on the top area of the steel pipe frame 1. The upper fixed hook 2 and the upper hook 301 are shaped and specially designed to firmly hold the top edge of the screen 3, ensuring that the screen 3 will not shake or fall off after installation.
[0053] The lower hook 302 at the bottom of the polyester screen 3 is engaged with the lower movable hook 4 located at the bottom of the steel pipe frame 1. The lower movable hook 4 slides in the bottom area of the steel pipe frame 1, matching the shape of the lower hook 302. Under the action of the subsequent elastic tensioning mechanism, it can work together with the upper fixed hook 2 to tighten the screen 3, providing convenience and stability for installation.
[0054] Tensioned polyester screen 3
[0055] The tension spring 7, as a key component of the elastic tensioning mechanism, is connected at one end to the lower end of the guide rod 6 and at the other end to the base 10 (via the fixed rod 8). After the screen 3 is installed, the spring is stretched, generating a continuous downward pulling force. This tension structure design, which transmits the force through the guide rod 6, allows the pulling force to be transmitted evenly and stably to the lower movable hook 4, working together with the upper fixed hook 2 to evenly tighten the polyester screen 3.
[0056] The guiding mechanism (guide channel steel 5 fixed to the bottom crossbeam of steel pipe frame 1, with multiple guide holes 501, the top end of guide rod 6 fixedly connected to the lower movable hook 4 and the lower end passing through the guide hole 501 and connected to the elastic tensioning mechanism) precisely guides the lower movable hook 4, ensuring its stable vertical movement along the extension direction of the polyester screen 3. This ensures uniform force distribution across all parts of the screen 3, preventing deformation or loosening caused by uneven local force. It guarantees stable and reliable tensioning of the screen 3 throughout the tensioning process, providing stable working conditions for subsequent cleaning operations.
[0057] Cleaning the polyester screen 3: After installing and tensioning the polyester screen 3, operate according to the acid washing and descaling method for the polyester screen 3. First, perform a preliminary physical rinse using high-pressure water to wash the surface of the screen 3, removing large, easily peelable pieces of sludge and initial scale. Then, immerse the screen 3 in a mixed acid solution of oxalic acid (2% by mass) and hydrochloric acid (2% by mass) prepared in a specific ratio for 12 hours (the time can be adjusted according to the severity of scaling) for chemical soaking treatment. Finally, remove the soaked screen 3 from the acid washing solution and thoroughly rinse the screen 3, which is taut on the cleaning support, again using high-pressure water until it is clean. During the cleaning process, the flat surface of the taut screen 3 reduces water scattering and rebound, improving the flushing efficiency and penetration of the high-pressure water flow on the dirt, resulting in a more ideal cleaning effect.
[0058] Disassembling the screen 3: After cleaning, in the reverse order of installation, first remove the lower movable hook 4 from the lower hook 302 of the screen, then separate the upper fixed hook 2 from the upper hook 301 of the screen, and carefully remove the cleaned polyester screen 3.
[0059] Maintenance and Storage: All components of the cleaning rack are made of corrosion-resistant metal materials. After use, promptly clean any residual pickling solution and impurities from the rack to prevent further corrosion. Regularly inspect and maintain the rack for loose, damaged, or worsened corrosion. Repair or replace components as needed. Store the cleaning rack in a dry, well-ventilated place to extend its service life.
[0060] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
