[0021] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The present invention provides an anti-clogging filtering device for trimethylolethane processing, such as Figure 1-5As shown, the anti-clogging filtering equipment for trimethylolethane processing includes: a filter box 1, two opposite inner side walls of the filter box 1 are fixedly mounted with two brackets 2 extending toward the center of the filter box, and a collecting hopper 3 is fixedly mounted between the ends of the two brackets 2; a filter cartridge 4, the filter cartridge 4 is arranged on the collecting hopper and is used to filter the trimethylolethane reaction solution; a box cover 5, the box cover 5 is arranged on the top of the filter box 1, and an injection pipe 6 is fixedly mounted on the box cover 5, the liquid outlet end of the injection pipe 6 is provided with an elbow located in the filter cartridge, and the liquid outlet end of the elbow faces the filter of the filter cartridge 4 surface; a first liquid outlet pipe 7, one end of the first liquid outlet pipe 7 is fixedly connected to the bottom center of the collecting bucket 3, and the other end of the first liquid outlet pipe 7 extends out of the filter box 1; an air jet pipe 8, one end of the air jet pipe 8 is in the filter box 1, and one end of the air jet pipe 8 is fixedly mounted with a plurality of nozzles facing the filter cartridge; a fan 9, the fan 9 is fixedly mounted on the outside of the filter box 1, and the air outlet end of the fan 9 is connected to the other end of the air jet pipe 8 through the air outlet pipe 10; a driving mechanism, the driving mechanism is arranged on the filter cartridge 4 and the filter box 1, and is used to drive the filter cartridge 4 to rotate.

[0023] In this embodiment, the filter box 1 provides a closed environment for the entire filtration process, preventing the solution from splashing and impurities from diffusing to the outside, ensuring the cleanliness and safety of the working area, and also facilitating the integrated installation of internal equipment. The bracket 2 is fixed in the filter box 1, and plays the role of firmly supporting the collecting bucket 3. The collecting bucket 3 is located below the filter cartridge 4, and its function is to collect the impurity liquid filtered by the filter cartridge 4. When the filter cartridge 4 filters the trimethylolethane reaction solution, the solid impurities are blocked outside the filter cartridge 4 and fall into the collecting bucket 3 under the action of gravity. Then they can be discharged through the first liquid outlet pipe 7. This can effectively collect and process the impurities and avoid the impurities from arbitrarily accumulating in the filter box 1 and affecting the normal operation of the equipment; the rotatable filter cartridge 4 is the core filtering component, and its rotatable design is a highlight. During the filtration process, due to its continuous rotation, compared with the traditional fixed filter cartridge, the solid suspended matter in the solution is not easy to continue to adhere to the same position of the filter cartridge 4 to form a stubborn clogging layer. When tiny sodium or calcium formate suspended solids approach the filter cartridge 4, the rotation of the filter cartridge 4 causes the time and position of these suspended solids in contact with the filter cartridge 4 to continuously change, reducing the possibility of them remaining on the surface of the filter cartridge 4 for a long time and gradually accumulating. This maintains the good filtration performance of the filter cartridge 4 and effectively reduces the problem of reduced filtration efficiency caused by clogging. The box cover 5 covers the top of the filter box 1. On the one hand, it can prevent dust and other external impurities from falling into the filter box 1 and contaminating the reaction solution. On the other hand, it provides a mounting base for components such as the injection pipe 6. The liquid outlet of the injection pipe 6 is provided with an elbow and the liquid outlet end faces the filter surface of the filter cartridge 4. This design allows the trimethylolethane reaction solution to be filtered to rush toward the filter surface of the filter cartridge 4 at a certain angle and direction. During the solution impact process, some solid suspended solids may be directly washed off due to the impact force and will not immediately adhere to the filter cartridge 4. This reduces the risk of clogging during the initial filtration of the filter cartridge 4 to a certain extent, which is conducive to maintaining the filtration efficiency of the filter cartridge 4. The fan 9 generates a strong airflow, which is transported to the injection pipe 8 through the outlet pipe 10. The multiple nozzles on the air jet pipe 8 spray the airflow evenly onto the inner wall of the filter cartridge 4. During the filtration process, when some solid impurities inevitably adhere to the inner wall of the filter cartridge 4, the airflow ejected from the air jet pipe 8 can blow these impurities off. This jet cleaning method can clean the filter cartridge 4 in real time without stopping the operation of the filtration equipment, avoiding the problem of reduced production efficiency due to shutdown for cleaning. Moreover, compared with traditional manual or mechanical cleaning methods, cleaning by airflow is more efficient and uniform, and can comprehensively remove impurities at different positions on the inner wall of the filter cartridge 4, keep the filter aperture of the filter cartridge 4 unobstructed, and thus ensure the stability of the filtration efficiency; the driving mechanism is installed on the filter cartridge 4 and the filter box 1, and its main function is to drive the filter cartridge 4 to rotate.By continuously providing rotational power to the filter cartridge 4, the filter cartridge 4 is always in motion during the filtration process, which is not only conducive to reducing the adhesion of solid suspended matter on the surface of the filter cartridge 4, but also, in conjunction with the solution impact of the injection pipe 6 and the jet cleaning of the jet pipe 8, it can maintain the good filtration state of the filter cartridge 4 in all directions, prevent the reduction of filtration efficiency due to the accumulation of solid impurities, extend the service life of the filter cartridge 4, reduce the frequency and cost of equipment maintenance, and improve the overall efficiency of trimethylolethane processing and production.

[0024] In a further preferred embodiment of the present invention, the driving mechanism includes: a motor 12 fixedly mounted on the inner wall of the filter box 1; a ring gear 11 fixed on the outer surface of the filter cartridge 4; and a gear 13 fixed on the output shaft of the motor 12, the gear 13 being engaged with the ring gear 11.

[0025] In this embodiment, the motor 12: as the power source of the driving mechanism, the motor 12 is fixedly mounted on the inner wall of the filter box 1 and can provide stable power output. The rotational power outputted by the motor 12 is transmitted to the filter cartridge 4 through the subsequent transmission components, so that the filter cartridge 4 can rotate continuously and stably in the filter box 1. The parameters such as the rotation speed of the motor 12 can be adjusted according to the actual filtering requirements. For example, when there are many suspended solids in the solution, the rotation speed of the motor 12 can be appropriately increased to enhance the rotation effect of the filter cartridge 4 to better prevent the suspended solids from adhering; when there are fewer suspended solids, the rotation speed can be appropriately reduced to save energy and reduce equipment wear. The ring gear 11 fixed on the filter cartridge 4 is one of the key components of the transmission. It is closely connected to the filter cartridge 4. When the output power of the motor 12 is transmitted through the gear 13, the ring gear 11 can evenly transmit this rotational motion to the entire filter cartridge 4, ensuring that the filter cartridge 4 is evenly stressed and rotates smoothly. The design of the ring gear 11 makes the rotation of the filter cartridge 4 more reliable, avoiding problems such as jamming or damage to the filter cartridge 4 caused by localized uneven force. This helps maintain the stable operation of the filter cartridge 4 during long-term filtration, thereby maintaining good filtration efficiency and preventing excessive accumulation of solid impurities on the surface of the filter cartridge 4 due to abnormal rotation of the filter cartridge 4, which would affect the filtration effect. The gear 13 fixed to the output shaft of the motor 12 meshes with the ring gear 11, forming an effective transmission system. The gear 13 decelerates the high-speed rotational motion output by the motor 12 and transmits it to the ring gear 11. This reduction transmission can adjust the speed ratio according to the actual rotation requirements of the filter cartridge 4, allowing the filter cartridge 4 to rotate at an appropriate speed. At the same time, the meshing method of the gear 13 and the ring gear 11 ensures the accuracy and stability of power transmission, reduces energy loss and fluctuations during power transmission, further ensures the smooth and reliable rotation of the filter cartridge 4, and helps to continuously and effectively prevent solid impurities from clogging the filter cartridge 4 during the filtration process, thereby ensuring the filtration efficiency and quality of the trimethylolethane reaction solution.

[0026] In a further preferred embodiment of the present invention, a baffle 18 is fixedly installed on the bottom of the box cover 5, and the bottom end of the baffle 18 extends into the filter cartridge 4 and is located between the center of the filter cartridge and the air jet pipe to block impurities from being blown onto the mesh surface.

[0027] In this embodiment, the baffle 18 fixedly mounted on the bottom of the box cover 5 and extending into the filter cartridge 4 at its bottom end plays a key role. During the process of the air jet 8 jetting to clean the impurities on the inner wall of the filter cartridge 4, the airflow will drive the impurities blown off to move inside the filter cartridge 4. The presence of the baffle 18 can effectively block these impurities carried by the airflow and prevent them from being blown back onto the filter mesh surface of the filter cartridge 4. Without the baffle 18, the impurities blown off may be reattached to the mesh surface of the filter cartridge 4 that has just been cleaned under the action of the airflow, resulting in a significant reduction in the cleaning effect, the filter cartridge 4 will soon be blocked again, and the filtration efficiency will drop sharply. With the baffle 18, the impurities will be blocked by it and fall back into the collection bucket 3 under the action of gravity, thereby ensuring the effectiveness of the air jet cleaning by the air jet 8, allowing the filter cartridge 4 to maintain good filtration performance for a long time, reducing the need for frequent maintenance caused by repeated attachment of impurities, improving the stability and continuity of the trimethylolethane processing filtration process, and ensuring production efficiency.

[0028] In a further preferred embodiment of the present invention, a mounting box 14 is fixedly installed on one side of the filter box 1, and the mounting box 14 is located below the other end of the first liquid outlet pipe 7. A removable filter box 15 is provided in the mounting box 14 for filtering the impurity liquid discharged from the first liquid outlet pipe 7.

[0029] In this embodiment, the mounting box 14 is fixedly mounted on one side of the filter box 1 and is intentionally arranged below the liquid outlet end of the first liquid outlet pipe 7. Its main function is to provide a stable mounting position for the filter box 15. This allows the subsequent processing components for filtering the impurity liquid to be integrated around the filter box 1, facilitating the overall layout and management of the equipment. It also ensures that when the filter box 15 is subsequently operated, its position is relatively fixed and easy to find, making it convenient for maintenance personnel to perform related maintenance and replacement operations. The filter box 15 is arranged in the mounting box 14 and can be pulled out and removed. This design has many beneficial effects. First, when the impurities filtered out by the filter cartridge 4 are discharged through the first liquid outlet pipe 7, the impurity liquid may still contain some impurities such as fine solid particles. The filter box 15 can further filter the impurity liquid discharged from the first liquid outlet pipe 7, playing the role of secondary filtration, thereby more effectively intercepting these remaining impurities.

[0030] In a further preferred embodiment of the present invention, the bottom of the installation box 14 is fixedly connected to a second liquid outlet pipe 16 , and the liquid outlet end of the second liquid outlet pipe 16 extends into the filter box 1 .

[0031] In this embodiment, the second liquid outlet pipe 16 fixedly connected to the bottom of the installation box 14 plays an important role in liquid diversion. After the filter box 15 filters the impurity liquid discharged from the first liquid outlet pipe 7, the filtered liquid is transported through the second liquid outlet pipe 16, and its liquid outlet end extends into the filter box 1. This design allows the liquid after secondary filtration to enter the filter box 1, which can reduce waste.

[0032] In a further preferred embodiment of the present invention, a drain pipe 17 is fixedly connected to the bottom of the filter box 1 for discharging the filtered trimethylolethane reaction solution.

[0033] In this embodiment, the drain pipe 17 is used to discharge the filtered trimethylolethane reaction solution into a collection container, or to connect the equipment pipelines of the next process to supply liquid.

[0034] In a further preferred embodiment of the present invention, a ball is embedded in the top of the collecting hopper 3, and an annular groove is provided at the bottom of the filter cartridge 4, and the annular groove is adapted to fit the ball.

[0035] In this embodiment, the balls embedded in the top of the collection hopper 3 play a key role in supporting and assisting the rotation. When the filter cartridge 4 is rotated by a drive mechanism such as a transmission system consisting of a motor 12, a gear 13, and a ring gear 11, the balls are in direct contact with the bottom of the filter cartridge 4. Due to the characteristics of the balls themselves, they can distribute the weight of the filter cartridge 4 more evenly, making the support force on the filter cartridge 4 more balanced during rotation, avoiding wear or jamming that may occur due to excessive local force, helping to extend the service life of the filter cartridge 4, ensuring that the filter cartridge 4 can rotate continuously and stably, and thus maintaining good filtering performance. The annular groove at the bottom of the filter cartridge 4 is compatible with the balls at the top of the collection hopper 3, forming an ingenious matching structure. The annular groove provides a precise accommodation space for the balls, allowing the balls to accurately roll in the annular groove during the rotation of the filter cartridge 4, limiting the range of movement of the balls, and ensuring that the relative position relationship between the balls and the filter cartridge 4 remains stable.

[0036] In summary, the rotatable filter cartridge 4 reduces the adhesion of suspended solids and maintains good filtration performance; the box cover 5 prevents impurities from falling in and provides an installation base for the injection pipe 6. The special design of the injection pipe 6 reduces the risk of initial clogging; the fan 9 and the jet pipe 8 spray cleaning to keep the aperture of the filter cartridge 4 unobstructed, avoiding downtime for cleaning; the drive mechanism enables the filter cartridge 4 to rotate stably and cooperates with other components to maintain a good filtration state in all directions. The motor 12 provides power and can adjust the speed as needed. The ring gear 11 evenly transmits power to ensure the smooth rotation of the filter cartridge 4. The gear 13 ensures stable and reliable transmission. The baffle 18 prevents impurities from re-attaching during jet cleaning, effectively preventing the filter cartridge 4 from clogging, improving filtration efficiency and quality, reducing the frequency and cost of equipment maintenance, and improving the stability, continuity and overall efficiency of trimethylolethane processing.
