Description

Technical Field

[0001] The invention belongs to the technical field of rubber preparation, and in particular relates to a precision filter for preparing a rubber anti-aging agent. Background Art

[0002] During long-term storage and use, rubber and its products will gradually become sticky, hard, brittle or cracked due to the effects of heat, oxygen, ozone, variable valence metal ions, mechanical stress, light, high-energy rays, and erosion by other chemicals and molds. This phenomenon of physical and mechanical properties declining and elasticity decreasing over time is called aging. As the aging process proceeds and develops, the performance of rubber and its products will gradually deteriorate to the point where they completely lose their use value. For this reason, certain chemicals need to be added to rubber and its products to improve their resistance to the above-mentioned destructive effects, delay or inhibit the aging process, and thus extend the storage period and service life of rubber and its products. These substances are called antioxidants and are usually filtered during the preparation process to improve their accuracy.

[0003] In the prior art, the primary filtration devices used in the production process of rubber anti-aging agents generally have the technical problem of easy clogging. Since the reaction liquid contains components such as viscous substances, high molecular polymers and solid catalyst residues, these impurities will quickly form a dense sedimentation layer on the surface of the filter material at the beginning of filtration. As the operation time increases, the filter pores are gradually blocked, causing the system pressure to continue to rise and the filtration efficiency to decrease significantly. This not only causes frequent interruptions to the production process for maintenance and cleaning, but also seriously affects the continuity and stability of the overall process. Especially when dealing with mixed systems containing organic solvents, the volatility of the solvent will cause impurities to adhere more stubbornly to the filter medium, making it difficult to completely restore the filtration performance by conventional backwashing or mechanical cleaning methods. Ultimately, the equipment maintenance cost remains high, becoming a key bottleneck restricting the improvement of production efficiency.

[0004] Based on this, the present invention designs a precision filter for preparing a rubber anti-aging agent to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem in the prior art that the primary filter used in the production of rubber anti-aging agents is easily clogged due to crystallization caused by viscous impurities and solvent volatilization, resulting in reduced filtration efficiency and the need for frequent shutdowns for cleaning, which seriously affects production continuity. A precision filter for the preparation of rubber anti-aging agents is proposed to solve the problem that the primary filter used in the production of rubber anti-aging agents is easily clogged due to crystallization caused by viscous impurities and solvent volatilization, resulting in reduced filtration efficiency and the need for frequent shutdowns for cleaning, which seriously affects production continuity.

[0028] 1. In the present invention, when the filter plate needs to be cleaned, it is only necessary to start the driving motor, and the output shaft of the driving motor is linked with the rotating shaft to drive the gear transmission. The rotational motion of the gear is converted into the circumferential rotation of the gear ring. The gear ring realizes smooth rotation through the sliding fit between the slide plate and the inner circular groove of the cover plate. The connecting plate fixed to the gear ring drives the inclined cleaning brush to make a circular motion. The cleaning brush rotates on the surface of the filter plate to scrape off the sediment. The inclination angle design can guide the peeled crystals to the inner wall area of ​​the cover plate. The synchronously started fan generates a negative pressure adsorption effect through the dust collecting hood. The peeled crystal particles follow the air flow through the discharge pipe into the filter cartridge for collection. The purified gas is discharged through the air outlet and the exhaust end of the fan, forming a closed-loop cleaning and recovery system.

[0029] 2. In the present invention, a water flow sensor is integrated in the downstream pipeline of the filter plate to monitor the volume flow of the material flowing through it in real time. The water flow sensor transmits the collected flow data to the control unit of the buzzer alarm through a signal wire. When the measured flow rate is lower than the preset threshold (indicating that the filter plate is clogged), the control unit triggers the buzzer to emit an audible and visual alarm. This linkage mechanism enables the operator to accurately grasp the clogging status of the filter plate and respond in time to notify the operator to clean it, thereby avoiding an increase in pressure difference or a decrease in filtration efficiency due to clogging.

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0039] See also Figures 1-6 The present invention provides a technical solution: a precision filter for preparing a rubber anti-aging agent, comprising a filter body 1 and a pipeline 2, wherein the pipeline 2 is provided under the filter body 1, a cover plate 3 is clamped on the filter body 1, a feed port 8 is opened in the cover plate 3, a filter plate 4 is mounted on the upper surface of the filter body 1, a cleaning device 5 is mounted in the cover plate 3, a dust collecting device 6 is clamped in the cover plate 3, and an alarm device 7 is installed at the connection between the filter body 1 and the pipeline 2;

[0040] The cleaning device 5 includes a driving motor 51, the output end of the driving motor 51 is fixedly connected to a rotating shaft 52, one end of the rotating shaft 52 is fixedly connected to a gear 53, the gear 53 is externally meshed with a gear ring 54, the lower surface of the gear ring 54 is fixedly connected to a connecting plate 55, and the lower surface of the connecting plate 55 is fixedly connected to a cleaning brush 56.

[0041] Specifically, such as Figure 2-Figure 5 As shown, the cleaning device 5 also includes three slides 57, which are fixedly connected to the upper surface of the gear ring 54. A circular groove is provided in the cover plate 3. The three evenly distributed slides 57 and the circular groove in the cover plate 3 form a rotating pair, forming a stable three-point support system. This design enables the gear ring 54 to maintain dynamic balance during high-speed rotation, effectively suppressing the vibration caused by uneven force on the cleaning brush 56. The arc-shaped contact surface of the circular groove is treated with a wear-resistant coating, and the clearance fit accuracy with the slide 57 is controlled within 0.05mm, which ensures smooth rotation and prevents material particles from entering the sliding gap. Compared with the single-point support structure, this matching method improves the running stability of the gear ring 54 by more than 40%, significantly extending the service life of the transmission components.

[0042] The sliding plate 57 and the circular groove form a rotating connection, the connecting plate 55 is L-shaped, and the cleaning brush 56 overlaps the upper surface of the filter plate 4. The connecting plate 55 is arranged in an inclined shape to facilitate the accumulation of waste materials in one place. The special structural design of the L-shaped connecting plate 55 provides a stable support base for the cleaning brush 56, and its vertical section is rigidly connected to the gear ring 54 to ensure the power transmission efficiency. The horizontal extension section enables the cleaning brush 56 to form an optimal contact angle with the surface of the filter plate 4. With the inclined cleaning brush 56, during the rotation process, it can not only efficiently scrape off the crystallized deposits on the surface of the filter plate 4, but also continuously push the stripped impurities toward the dust collecting hood 62 through the guiding effect generated by the inclined angle. This combined structure avoids cleaning dead corners and reduces the load of the drive motor 51 through mechanical optimization.

[0043] The dust collecting device 6 includes a discharge pipe 61, which is connected to the cover plate 3. One end of the discharge pipe 61 is provided with a dust collecting hood 62, and a sealing shell 66 is fixedly connected to the dust collecting hood 62. A shell 64 is installed in the sealing shell 66, and a filter cartridge 63 is installed in the shell 64. The filter cartridge 63 is fixedly connected to the bottom of the dust collecting hood 62. An air outlet 65 is opened in the shell 64, and a fan 67 is connected to the sealing shell 66. The input end of the fan 67 is connected to the air outlet 65. A rubber pad for sealing is provided at the connection between the dust collecting hood 62 and the sealing shell 66. An annular air flow channel is formed between the outer sealing shell 66 and the inner shell 64. This nested structure creates a double protective barrier. When the system is running, the air flow between the inner and outer layers not only plays a heat insulating role, but also effectively blocks the invasion of external moisture, providing a dry and stable working environment for the internal precision components, and is particularly suitable for long-term use under humid working conditions.

[0044] A locking plate 68 is fixedly connected to the lower part of the fan 67, and a connecting block 69 is fixedly connected to one side of the housing 64. The connecting block 69 is fixedly connected to the outside of the filter body 1. The position of the discharge pipe 61 is above the filter plate 4, and the discharge pipe 61 is set to be inclined downward. The inclined discharge pipe 61 is designed at a specific angle, and its opening direction is physically isolated from the material flow direction. Under normal working conditions, the fluid dynamics of the filtered material will cause it to flow horizontally along the surface of the filter plate 4, and the opening position of the downward-sloping discharge pipe 61 avoids the main flow channel, ensuring that the material will not flow in naturally due to gravity. Only when When the fan 67 is started to generate negative pressure suction, the crystal particles peeled off by the cleaning brush 56 will overcome the angular resistance of the inclined pipe 2 under the action of the directional airflow and be sucked into the collection system. This "normally closed" design fundamentally eliminates the possibility of normal materials accidentally entering the discharge channel; the downward-inclined discharge pipe 61 and the dust hood 62 constitute a Venturi effect acceleration channel. When the fan 67 is started, the design of the inclined pipe 2 enables the crystal particles to slide towards the entrance of the dust hood 62 with the assistance of gravity, and the gradually expanding structure of the dust hood 62 reduces the airflow velocity to form a low-pressure area. The synergistic effect of the two improves the adsorption efficiency.

[0045] Specifically, such as Figure 6 As shown, the alarm device 7 includes a water flow sensor 71, which is fixedly connected between the filter body 1 and the pipe 2. A wire 72 is fixedly connected to one side of the water flow sensor 71, and one end of the wire 72 is fixedly connected to a buzzer alarm 73. A base 74 is fixedly connected under the buzzer alarm 73, and the base 74 is fixedly connected to the upper surface of the pipe 2. The water flow sensor 71 and the buzzer alarm 73 are electrically connected through the wire 72.

[0046] Working principle, when in use: when the filter plate 4 needs to be cleaned, just start the drive motor 51, the output shaft of the drive motor 51 is linked with the rotating shaft 52, driving the gear 53 to transmit, and the rotational motion of the gear 53 is converted into the circumferential rotation of the gear ring 54, and the gear ring 54 is smoothly rotated by the sliding fit between the slide plate 57 and the inner circular groove of the cover plate 3. The connecting plate 55 fixedly connected to the gear ring 54 drives the inclined cleaning brush 56 to make a circular motion, and the cleaning brush 56 rotates on the surface of the filter plate 4 to scrape off the sediment. The tilt angle design can guide the peeled crystals to the inner wall area of ​​the cover plate 3, and the fan 67 started synchronously generates a negative pressure adsorption effect through the dust collecting hood 62 The peeled crystal particles follow the air flow through the discharge pipe 61 into the filter cartridge 63 for collection, and the purified gas is discharged through the air outlet 65 and the exhaust end of the fan 67. A water flow sensor 71 is integrated in the downstream pipeline 2 of the filter plate 4 to monitor the volume flow of the material flowing through in real time. The water flow sensor 71 transmits the collected flow data to the control unit of the buzzer alarm 73 through the signal wire 72. When the measured flow rate is lower than the preset threshold (indicating that the filter plate 4 is blocked), the control unit triggers the buzzer alarm 73 to emit an audible and visual alarm. This linkage mechanism enables the operator to accurately grasp the blockage status of the filter plate 4 and respond in time to notify the operator to clean it.

[0047] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
