Abstract
Description
Technical Field
[0001] This utility model relates to the field of mixing equipment, specifically a raw material oil additive premixing equipment. Background Technology
[0002] Raw material oil usually refers to hydrocarbon base oils formed after preliminary processing of coal tar, anthracene oil, etc. It mainly comes from coking by-products. Its components are mainly polycyclic aromatic hydrocarbons, and it has a certain viscosity and calorific value. In carbon black production, raw material oil is often used as the main feed. By adding specific additives, its physicochemical properties are adjusted to meet the requirements of subsequent processes, and it is finally used to produce carbon black, fuel oil or other chemical products.
[0003] Premixing equipment is a specialized device used to premix raw oil with additives and other materials in a uniform manner. Through mechanical stirring, materials with different properties are fully integrated to form a stable mixed oil, providing uniform and reliable feeding conditions for carbon black production. This equipment is widely used in the chemical, energy and materials industries and can effectively improve production efficiency and the consistency of the final product.
[0004] Currently, most premixing equipment still uses simple feeding operations, and the ratio of raw materials to additives is not accurately controlled, which easily leads to uneven mixing and affects the stability of the carbon black production process and product quality. Therefore, a raw material oil and additive premixing equipment is proposed to address the above problems. Utility Model Content
[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A raw material oil additive premixing device of this utility model includes a container; a cover plate is fixedly connected to the top of the container; a fixed seat is fixedly connected to the top of the cover plate; a flow meter is fixedly connected to the top of the fixed seat; a feed pipe is fixedly connected to the side wall of the fixed seat; a storage box is fixedly connected to the top of the cover plate; a valve is fixedly connected to the top of the container; the flow meter is connected to the storage box and the valve; a motor is fixedly connected to the top of the cover plate; a stirring blade is fixedly connected to the output end of the motor; and a discharge port is fixedly connected to the side wall of the container. The flow meters record the flow rates of the raw material oil and the additives respectively. Based on the amount of raw material oil injected, the amount of additive added can be controlled to ensure a uniform ratio between the two, reducing the imbalance caused by inconsistent addition of raw material oil and additives, achieving premixing of raw material oil and additives, and improving the stability of the premixed material. The setting of the feed pipe and storage box also increases the convenience of adding materials into the container, reducing the need to transport materials into the container after measurement.
[0007] Preferably, a heating plate is fixedly connected to the bottom of the container; a groove is formed on the inner side wall of the container; multiple sets of heating rods are fixedly connected to the bottom of the groove; the heating rods are arranged in an array at the bottom of the container; the heating plate at the bottom of the container heats the material at the bottom of the container, while the heating rods in the groove heat the liquid in the cavity, forming a surrounding heating of the entire container, increasing the temperature of the material, promoting the fusion of additives and raw oil, and shortening the mixing time.

[0009] Preferably, a scraper is fixedly connected to the side wall of the stirring blade; a cutter is fixedly connected to the side wall of the stirring blade; when the stirring blade rotates, the scraper contacts the inner side wall of the container, scraping off the raw material oil and additives adhering to the inner side wall of the container, which can reduce the material adhesion and solidification, and the cutter can break up the additives or raw material oil, making them easier to blend with other materials.
[0010] Preferably, a flexible pad is fixed to the side wall of the scraper; the flexible pad is slidably connected to the inner side wall of the cover plate; by using the flexible pad between the scraper and the container, the direct contact between the scraper and the inner side wall of the container can be reduced, the direct friction between the scraper and the inner side wall of the container can be reduced, and the noise and wear caused by the friction between the scraper and the inner side wall of the container can be reduced.
[0011] Preferably, a water pump is fixedly connected to the top of the cover plate; an interface is fixedly connected to the side wall of the water pump; after the cleaning liquid is connected through the interface, it is sprayed directly into the container. With the rotation of the stirring blade, the cleaning liquid can evenly cover the inside of the container, reducing material residue inside the container and preventing contamination during the next use.
[0012] The advantages of this utility model are: 1. The raw oil additive premixing device of this utility model records the flow rates of raw oil and additives separately using flow meters.

Heating rod 22 can heat the liquid inside groove 21, so that the container 1 can maintain a constant temperature. When the raw oil and additives inside container 1 are mixed, the pump 3 can be started. The pump pipe 31 can draw out the raw material at the bottom of container 1, and then flow through the discharge pipe 32 and flow back into the container 1 from the top of cover plate 11. When the stirring blade 18 rotates, the scraper 4 can contact the inner wall of container 1 and scrape off the material attached to the inner wall of container 1. The cutter 41 can cut the raw material inside container 1. When the scraper 4 scrapes the material on the inner wall of container 1, the flexible pad 5 can contact the inner wall of container 1, so that the flexible pad 5 is spaced between the scraper 4 and container 1.
