Description

Technical Field

[0001] This utility model relates to the field of filtration pretreatment technology, specifically to a chemical raw material pretreatment device with automatic impurity filtration function. Background Technology

[0002] Before entering subsequent production processes such as polymerization, reaction, and refining, chemical raw materials need to be pretreated to remove solid impurities and particulate contaminants. This is to prevent impurities from scratching the inner walls of production equipment, clogging conveying pipelines, or affecting the purity of the final product. Therefore, the filtration efficiency and precision of the raw material pretreatment process are directly related to the continuity of chemical production, the stability of product quality, and the safety of equipment operation. Pretreatment devices with automatic impurity filtration functions have become an indispensable key piece of equipment in modern chemical production lines because they can reduce the frequency of manual intervention and reduce operational intensity.

[0003] In existing chemical raw material pretreatment filtration devices, filter plates are often directly slidably connected to the support structure. After long-term use, the sliding gap is prone to displacement, leading to deviation of the raw material filtration path, uneven local filtration load, and consequently, decreased filtration accuracy and fluctuations in raw material purification quality. Furthermore, impurities adhering to the surface of the filter plates require regular manual cleaning, and machine shutdown is necessary when the filter holes become clogged, severely disrupting the production process and reducing processing efficiency. Therefore, this utility model proposes a chemical raw material pretreatment device with automatic impurity filtration function to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, such as low filtration accuracy, easy wear of components, and inconvenient maintenance, this invention achieves efficient and stable automatic filtration of chemical raw materials by incorporating wear-resistant bushings between the filter plate and slide bar, a brush plate and cam vibration mechanism, and detachable side plates. This avoids problems such as filter plate misalignment, impurities clogging filter holes, rapid component wear, and difficult maintenance of filter components.

The vibration mechanism is used to drive the filter plate to vibrate, thereby shaking off the dust adhering to the outer wall of the filter plate.

[0006] Preferably, the vibration mechanism includes a cam rotatably connected to the lower end of the transmission box, the cam flange being in contact with the outer wall of the filter plate, and two sets of springs being sleeved on the outer wall of each set of slide rods, one end of each set of springs being in contact with the outer walls of both sides of the filter plate, and the other end of each spring being fixedly connected to the outer wall of its adjacent side plate.

[0010] Preferably, the radius of the second transmission wheel is smaller than the radius of the first transmission wheel.

[0011] (III) Beneficial Effects Compared with the prior art, this utility model provides a chemical raw material pretreatment device with automatic impurity filtration function, which has the following beneficial effects: 1. This utility model significantly reduces the sliding gap between the filter plate and the slide rod by setting a wear-resistant bushing at the contact point, thus avoiding problems such as disordered raw material filtration path and uneven local load caused by filter plate misalignment during filtration, and ensuring the stability of raw material purification quality. At the same time, the brush plate on the outer wall of the transmission box works in conjunction with the vibration mechanism. The brush plate can clean the impurities attached to the outer wall of the filter plate in real time, and the vibration mechanism drives the filter plate to vibrate continuously through cam push and spring reset, which can quickly shake off the impurities clogging the filter holes without manual shutdown for cleaning, reducing the frequency of production process interruption and improving the efficiency of raw material pretreatment.

[0012] 2. This utility model reduces direct wear between the cam and the filter plate by wrapping an elastic, wear-resistant rubber pad around the outer wall of the cam flange. The spring is made of high-strength stainless steel with an elastic coefficient adapted to the weight of the filter plate, preventing unstable filter plate reset due to spring elasticity decay. Simultaneously, the side plate is detachably bolted to the inner wall of the treatment box, facilitating subsequent maintenance and replacement of components such as the slide rod and filter plate, shortening maintenance time and reducing operational complexity. Furthermore, the radius ratio of transmission wheel one to transmission wheel two can be adjusted according to the viscosity of the raw material, allowing the rotation speed of the rotating rod and brush plate to adapt to different working conditions, further improving the applicability and operational stability of the device.

[0015] This utility model provides a technical solution for a chemical raw material pretreatment device with automatic impurity filtration function: Please see Figure 1-4 A chemical raw material pretreatment device with automatic impurity filtration function includes a treatment box 1. Both ends of the treatment box 1 are equipped with connecting pipes 2 and flanges 3. A filter plate 10 is movably connected inside the treatment box 1. The perforated part of the outer wall of the filter plate 10 is circular. Side plates 11 are symmetrically arranged at the four corners of the filter plate 10. Sliding rods 12 are fixedly connected between the symmetrically arranged side plates 11. The filter plate 10 is slidably connected to the outer wall of the sliding rods 12. A transmission box 7 is fixedly connected to the top inside the treatment box 1. A brush plate 14 is rotatably connected to the outer wall of the transmission box 7. The brush plate 14 rotates on the outer wall of the filter plate 10. A vibration mechanism is installed on the outer wall of the transmission box 7. The vibration mechanism is used to drive the filter plate 10 to vibrate, thereby shaking off the dust adhering to the outer wall of the filter plate 10. Furthermore, a wear-resistant bushing is provided at the contact point between the filter plate 10 and the slide rod 12. The wear-resistant bushing is fitted on the outer wall of the slide rod 12 and fixedly connected to the inner wall of the filter plate 10. Meanwhile, the side plate 11 is detachably connected to the inner wall of the treatment box 1 by bolts, which facilitates the subsequent maintenance and replacement of the slide rod 12 and the filter plate 10.

[0016] The vibration mechanism includes a cam 17 rotatably connected to the lower end of the transmission box 7. The flange of the cam 17 is in contact with the outer wall of the filter plate 10. Each set of slide rods 12 is fitted with two sets of springs 13 on the outer wall. One end of each set of springs 13 is in contact with the outer walls of both sides of the filter plate 10, and the other end of each spring 13 is fixedly connected to the outer wall of its adjacent side plate 11. Furthermore, the outer wall of the flange of the cam 17 is wrapped with a layer of elastic wear-resistant rubber pad, which is fixed to the outer wall of the cam 17 by adhesive. Meanwhile, the spring 13 is made of high-strength stainless steel, and the elastic coefficient of the spring 13 is adapted according to the weight of the filter plate 10 to ensure that the spring 13 can stably drive the filter plate 10 to reset, and avoid the filter plate 10 vibration frequency from decreasing due to insufficient elasticity of the spring 13, which would affect the impurity shaking effect.

[0017] The transmission box 7 has a transmission cavity 15, and two sets of bevel gears 16 are rotatably connected in the transmission cavity 15. The two sets of bevel gears 16 mesh with each other and are coaxially fixedly connected to the brush plate 14 and the cam 17 respectively. The processing box 1 has a rotating rod 8 rotatably connected in the processing box 1. Multiple sets of blades 9 are arranged on the outer circumference of the rotating rod 8. The end face of the processing box 1 is rotatably connected to a transmission wheel 4 and a transmission wheel 5. The transmission wheel 4 and the transmission wheel 5 are connected to each other by a transmission belt 6. The transmission wheel 4 and the transmission wheel 5 are fixedly connected to the rotating rod 8 and the coaxial bevel gear 16, respectively. The radius of the transmission wheel 5 is smaller than that of the transmission wheel 4. Furthermore, the radius ratio of transmission wheel 4 to transmission wheel 5 is reasonably set according to the viscosity of the raw material and the processing requirements. This radius ratio can keep the rotating rod 8 at a low speed, avoiding excessive turbulence of high-viscosity raw materials under the push of the blade 9, while keeping the brush plate 14 at a high speed, improving the cleaning efficiency of impurities on the outer wall of the filter plate 10.

[0018] In practical use, the working principle of this utility model is as follows: In operation, chemical raw materials enter the processing tank 1 through the connecting pipes 2 at both ends and the end flanges 3. At this time, the rotating rod 8 inside the processing tank 1 begins to rotate, causing multiple sets of blades 9 arranged circumferentially on its outer wall to rotate synchronously. During the rotation of the rotating rod 8, it drives the transmission wheel 4, which is fixedly connected to it, to rotate synchronously. The transmission wheel 4 transmits power to the transmission wheel 5 via the transmission belt 6, causing the transmission wheel 5 to rotate accordingly. Because the radius of the transmission wheel 5 is smaller than that of the transmission wheel 4, and the radius ratio between the two is reasonably set according to the viscosity of the raw material and the processing requirements, the rotational speed of the bevel gear 16, which is coaxially fixed with the transmission wheel 5, is higher than that of the rotating rod 8. The two sets of meshing bevel gears 16 in the transmission cavity 15 inside the transmission box 7 transmit power to the brush plate 14 and the cam 17 respectively, ensuring that the rotation of the brush plate 14 and the rotation of the cam 17 remain synchronized.

[0019] As the raw material continuously flows to the filter plate 10, the filter plate 10 intercepts and filters impurities in the raw material. At the same time, the brush plate 14 on the outer wall of the transmission box 7 rotates around its own axis to clean the impurities attached to the outer wall of the filter plate 10 in real time, preventing impurities from clogging the porous structure of the filter plate 10 and ensuring that the filtration channel is unobstructed. During this process, the vibration mechanism on the outer wall of the transmission box 7 is activated simultaneously, and the cam 17 rotates around its rotation axis. When the flange of the cam 17 contacts the outer wall of the filter plate 10, it pushes the filter plate 10 to slide along the outer wall of the slide rod 12. At this time, the two sets of springs 13 sleeved on the outer wall of the slide rod 12 are compressed. When the flange of the cam 17 disengages from the filter plate 10, the springs 13 reset under their own elastic force, causing the filter plate 10 to slide in the opposite direction, thereby causing the filter plate 10 to vibrate continuously. The spring 13 is made of high-strength stainless steel, and its elastic coefficient is adapted to the weight of the filter plate 10, which can ensure that the filter plate 10 can be stably reset every time. At the same time, the elastic wear-resistant rubber pad wrapped on the outer wall of the flange of the cam 17 is fixed to the outer wall of the cam 17 by adhesive, which greatly reduces the wear when the cam 17 contacts the filter plate 10 and extends the service life of both.

[0020] In addition, the wear-resistant bushing at the contact point between the filter plate 10 and the slide rod 12 effectively reduces the sliding gap between them, preventing the filter plate 10 from shifting during the filtration process, ensuring filtration accuracy, and solving the problem of the filter plate 10 shifting and affecting the filtration effect in the prior art. The side plate 11 is detachably connected to the inner wall of the treatment box 1 by bolts, which facilitates the subsequent inspection and replacement of the slide rod 12 and the filter plate 10, avoiding the inconvenience of maintaining the filter components in traditional devices.

[0021] In summary, this device uses the rotation of the brush plate 14 and the continuous vibration of the filter plate 10 to promptly shake off and collect impurities. The filtered pure chemical raw materials are then discharged from the connecting pipe 2 at the other end of the treatment box 1. Through the coordination of its various structures, this device effectively solves the problems of low filtration accuracy, easy wear of components, inconvenient maintenance, and unstable operation in the prior art of chemical raw material pretreatment devices, achieving efficient and stable automatic filtration of chemical raw materials.

[0022] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
