Description

Technical Field

[0001] This utility model relates to the technical field of plasticizer production equipment, and in particular to an environmentally friendly rubber plasticizer production and processing device. Background Technology

[0002] Rubber plasticizers are important additives in the rubber industry, and their performance directly affects the processability, flexibility, and durability of rubber products. With increasingly stringent environmental regulations, environmentally friendly rubber plasticizers made from renewable resources such as vegetable oils and recycled oils have become a key development direction for the industry. However, these raw material oils usually contain a large amount of plant residues, gums, phospholipids, and solid impurities such as carbon black and metal fragments carried in recycled oils. They must be efficiently and thoroughly filtered and purified before production and processing. Otherwise, these impurities will poison the catalysts of subsequent esterification, epoxidation, and other reactions, leading to darker product color, decreased thermal stability, and potential blockage of equipment pipelines, seriously affecting product quality and production efficiency.

[0003] Currently, the filtration of crude oil mainly uses traditional vibrating screens or plate and frame filter presses. Vibrating screens rely on gravity and vibration for screening, which easily leads to screen clogging and low processing efficiency for crude oils with high viscosity and high solid content. Moreover, the open operation makes the oil prone to oxidation and deterioration. While plate and frame filter presses can provide a certain pressure, the process of loading and unloading filter cloths and cleaning filter residues is cumbersome, labor-intensive, and cannot effectively prevent the formation of filter cake during filtration, resulting in huge resistance and high energy consumption in the later stages of filtration. Therefore, there is an urgent need for an environmentally friendly rubber plasticizer production and processing device that can filter efficiently and automatically prevent clogging. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model discloses an environmentally friendly rubber plasticizer production and processing device. This utility model can not only effectively improve the filtration efficiency of high viscosity raw material oil through heating and filtration, but also agitate and collect impurity particles during the filtration process, which greatly improves the filtration quality of the raw material oil.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An environmentally friendly rubber plasticizer production and processing apparatus, comprising: The mounting frame includes a base plate, a vertical plate on one side of the base plate, and a top plate on the upper part of the vertical plate that is parallel to and corresponds to the bottom of the base plate. The cylindrical body is set on the surface of the vertical plate and is correspondingly set above and below the top plate. Both the upper and lower ends of the cylindrical body are open structures. The movable plate is located inside the opening at the upper end of the cylinder and is press-fitted with the inner wall of the cylinder. The injection pipe is located at the top of the cylinder, and its lower end is movable and sealed through the movable plate and extends into the cylinder to inject raw material oil into the cylinder. The filter plate is detachably installed inside the opening at the lower end of the cylinder and is used to filter the raw oil inside the cylinder. The lifting drive mechanism is located at the bottom of the top plate and connected to the movable plate. It is used to push the movable plate to apply downward pressure to the raw oil in the cylinder.

[0006] Furthermore, the side wall of the movable plate is provided with an annular mounting groove surrounding the movable plate, and a sealing ring is provided inside the annular mounting groove.

[0007] Furthermore, the lifting drive mechanism includes a power unit, a speed control unit, and a linear actuator.

The lower end of the injection pipe located inside the cylinder is provided with a stirring component that rotates synchronously with the injection pipe and is used to agitate the impurity particles on the upper part of the filter plate.

[0010] Furthermore, the rotation drive mechanism includes: The drive motor is located on the upper part of the top plate, and its output end is equipped with a drive gear; The transmission gear is located on the injection pipe body at the top of the top plate. The transmission gear is coaxial with the injection pipe and meshes with the drive gear.

[0011] Furthermore, the mixing component includes: The mounting ring is located on the injection pipe body inside the cylinder and is coaxially arranged with the injection pipe; Several L-shaped stirring rods are located at the bottom of the mounting ring and are evenly distributed along its circumference. The vertical ends of the L-shaped stirring rods are connected to the mounting ring, and the horizontal ends of the L-shaped stirring rods are set close to the surface of the filter plate.

[0012] Furthermore, the filter plate includes a plate body, the upper surface of the plate body is provided with several filter holes, and the outer edge of the upper surface of the plate body is provided with a collection groove arranged circumferentially along the plate body and used to collect large particulate impurities.

By using a lifting drive mechanism to push the movable plate to apply controllable pressure to the raw oil in the cylinder, pressure filtration is achieved, which greatly improves the filtration speed and is especially suitable for high viscosity oils. The stirring component driven by the rotary drive mechanism can continuously and mechanically agitate the impurity particles on the surface of the filter plate while the filter is being pressurized, effectively breaking the formation of the filter cake layer, avoiding clogging of the filter channels, achieving continuous, stable and efficient filtration, and reducing the number of times the machine needs to be stopped for cleaning. By setting collection grooves and leakage holes on the filter plate, the filtered impurity particles can be temporarily stored and collected, which greatly improves the quality and efficiency of raw oil filtration and facilitates the subsequent cleaning of impurity particles. By providing a sealing ring on the outer wall of the movable plate and using high-performance sealing components such as Glyd rings, the sealing reliability under high pressure is ensured. The removable filter plates make cleaning the filter residue and maintaining the equipment very convenient, reducing labor intensity and maintenance costs. By setting up a collection tank, the filtered raw oil can be collected and stored, which facilitates the subsequent processing of the filtered raw oil. This invention not only effectively improves the filtration efficiency of high-viscosity raw oil through heating filtration, but also agitates and collects impurity particles during the filtration process, greatly improving the filtration quality of the raw oil. This invention has a simple structure and is practical and convenient, integrating functions such as pressure filtration, mechanical stirring, impurity collection, and filtered oil collection into one unit. It effectively overcomes the shortcomings of traditional filtration equipment and provides a highly efficient, anti-clogging, intelligent, reliable, and environmentally friendly rubber plasticizer raw oil processing device with good industrial application prospects.
