Abstract
Description
Technical Field
[0001] This utility model relates to the field of petrochemical reactor technology, specifically to a non-clogging petrochemical reactor feeding device. Background Technology
[0002] Petrochemical reaction vessels are indispensable and important equipment in the petroleum and chemical industries. They are mainly used to complete various processes such as sulfidation, nitration, hydrogenation, hydrocarbonation, and condensation. They are not only the main site of chemical reactions, but also play a key role in many industries such as petroleum, chemical, pharmaceutical, agrochemical, and food.
[0003] However, when existing petrochemical raw materials are processed in the reactor, some auxiliary materials mixed with the main material have high viscosity. If stored in the feeding tank for a long time, they are prone to solidification in the feeding tank. This can cause pipe blockage during use and make it inconvenient to clean later, affecting the normal operation of the reactor. Secondly, since the observation window of the reactor is located on the top of the reactor, it is inconvenient to observe the inside of the reactor and to inspect and maintain the equipment installed on the top of the reactor.

[0020] The reactor body 2 and the feeding storage tank 3 are installed and fixed by the fixing frame 1. The feeding storage tank 3 stores the auxiliary materials for petrochemical production for later use. When the control valve 35 is turned on, the pump body 4 works. Under the operation of the pump body 4, the auxiliary materials stored in the feeding storage tank 3 are injected into the reactor body 2 through the feeding pipe 34 and the connecting pipe 41. When the auxiliary materials stored in the feeding storage tank 3 are not used up and are used again, the electric heating tube 33 installed in the installation chamber 32 is powered to heat the auxiliary materials stored in the feeding storage tank 3, so as to prevent the auxiliary materials from condensing in the feeding storage tank 3, which would be inconvenient for later cleaning, and cause the feeding pipe 34 to be blocked during feeding, which would affect the normal operation of the reactor.
[0021] A ladder 5 is fixedly installed on one side of the fixed frame 1, and a guardrail 6 is fixedly installed on the top surface of the fixed frame 1. The installation and positioning of the reactor body 2 is completed through the fixed frame 1. Climbing to the top of the fixed frame 1 via the ladder 5 allows for easy observation of the inside of the reactor body 2 through the observation window. It also facilitates maintenance of the equipment above the reactor body 2. At the same time, the guardrail 6 increases the safety of the staff above the fixed frame 1.
[0022] A mounting base 21 is fixedly installed in the middle of the top surface of the reactor body 2. A motor 22 is fixedly installed on the top surface of the mounting base 21. A stirring shaft 23 is fixedly installed at the output end of the motor 22.

A stirring paddle 25 is fixedly installed on the surface of the mounting sleeves 24. The motor 22 is installed and fixed through the mounting base 21. The stirring shaft 23 is positioned and rotated by bearings installed in the mounting base 21. The motor 22 drives the stirring shaft 23 to rotate. When the stirring shaft 23 rotates, it drives the stirring paddles 25, which are respectively installed in the mounting sleeves 24, to rotate inside the reactor body 2, thereby stirring and mixing the raw materials to be mixed into the reactor body 2.
[0023] A discharge pipe 26 is fixedly installed in the middle of the bottom surface of the reactor body 2. A valve 261 is installed on the surface of the discharge pipe 26 near the reactor body 2. The valve 261 and the discharge pipe 26 cooperate with each other. After the petrochemical raw materials have finished reacting in the reactor body 2, the valve 261 is opened and the raw materials that have finished reacting in the reactor body 2 are transported to the designated storage device for storage through the discharge pipe 26.
[0024] A feeding pipe 31 is fixedly installed on one side of the top surface of the feeding storage tank 3. The end of the feeding pipe 31 away from the feeding storage tank 3 is connected to the source of the auxiliary material. The auxiliary material is injected into the feeding storage tank 3 through the feeding pipe 31 for storage and later use.
[0025] A positioning frame 11 is fixedly installed on the bottom surface of the fixed frame 1. The reactor body 2 is fixedly clamped in the positioning frame 11. The positioning frame 11 and the reactor body 2 cooperate with each other, and the positioning frame 11 increases the firmness of the reactor body 2 after it is installed in the fixed frame 1.
[0026] The bottom surface of the reactor body 2 is fixedly equipped with three evenly distributed support legs 27. The three support legs 27 support the reactor body 2, thereby increasing the stability of the reactor body 2 after installation.
[0027] Working principle: The reactor body 2 and the feeding storage tank 3 are installed and fixed by the fixing frame 1. The feeding storage tank 3 stores the auxiliary materials for the production of petrochemicals for later use. When the control valve 35 is turned on, the pump body 4 works. Under the operation of the pump body 4, the auxiliary materials stored in the feeding storage tank 3 are injected into the reactor body 2 through the feeding pipe 34 and the connecting pipe 41. When the auxiliary materials stored in the feeding storage tank 3 are not used up, the electric heating tube 33 installed in the installation chamber 32 is powered to heat the auxiliary materials stored in the feeding storage tank 3, so as to prevent the auxiliary materials from condensing in the feeding storage tank 3, which would be inconvenient for later cleaning. During feeding, the feeding pipe 34 would be blocked, which would affect the normal operation of the reactor.
[0028] Climbing ladder 5 to the top of the fixed frame 1 allows for easy observation of the inside of the reactor body 2 through the observation window. It also facilitates maintenance of the equipment above the reactor body 2. Additionally, the guardrail 6 increases the safety of personnel above the fixed frame 1.
