Description

Technical Field

[0001] The invention belongs to the technical field of mixing and stirring devices, and in particular relates to a mixing and stirring device for petroleum production. Background Art

[0002] There are many chemical reactions involved in the oil refining process, such as cracking, reforming, and desulfurization. Stirring and mixing can increase the contact frequency and surface area between the reactants, thereby accelerating the chemical reaction rate. In the heating or cooling process of petroleum products, stirring and mixing helps to evenly distribute heat, prevent local overheating or overcooling, and ensure uniform temperature of the product. In some oil processing processes, solid catalysts or additives need to be evenly suspended in the liquid. The stirring and mixing device can ensure that these solid particles will not settle, thereby improving their effectiveness in the reaction. After long-term use of the stirring device, the impurities and sediments accumulated inside will affect the stirring efficiency, resulting in uneven mixing and affecting the quality of petroleum products. The long-term accumulation of sediments may cause additional burden on the impeller and shaft of the agitator, causing the impeller to bend or the shaft to break, reducing the service life of the equipment.

[0019] A stirring motor 10 passes through the upper cover 4 and is provided with stirring blades 13. A support base 11 is provided on the lower surface of the inner wall of the reactor 1. A discharge trough 12 is provided on the lower surface of the inner wall of the reactor 1 at the lower end of the support base 11. The stirring blades 13 are anchor structures that fit the inner wall of the reactor 1, which increase the efficiency of mixing and stirring and prevent impurities from accumulating on the inner wall of the reactor 1.

[0020] like Figure 5 As shown, the discharge mechanism includes two connecting cover plates 102 fixedly installed on one side of the discharge pipe 101, a sandwich ring 103 is provided between the two connecting cover plates 102, a rotating motor 106 is provided at the lower end of the sandwich ring 103, a rotating rod 105 penetrating the sandwich ring 103 is provided at the output end of the rotating motor 106, the rotating rod 105 is located between the sandwich rings 103 and a sealing circular plate 104 is fixedly installed, the sealing circular plate 104 is controlled to rotate by the rotating motor 106, so as to open the channel for discharge.

[0021] like Figure 6 , Figure 7 As shown, the cleaning mechanism includes a water pipe 201 fixedly installed at the output end of the hydraulic rod 9, a water inlet 202 is provided at the upper end of the outer surface of the water pipe 201, a connecting block 203 is provided at the lower end of the water pipe 201, a rotating head 204 is provided on one side of the connecting block 203, and four nozzles 205 arranged equidistantly are provided on the outer surface of the rotating head 204.

[0023] Working principle: The operator inputs petroleum and other materials into the reactor 1 through the feed port 5 opened on the surface of the reactor 1, and starts the stirring motor 10 at the upper end to stir the reactor 1. The stirring motor 10 is provided with a stirring blade 13 penetrating the upper cover 4 at the lower end. The stirring blade 13 is an anchor structure that fits the inner wall of the reactor 1 better and has a higher mixing efficiency, which is suitable for stirring materials with high viscosity such as petroleum. After the mixing and stirring work is completed, the discharge mechanism fixedly installed on one side of the discharge pipe 101 is used for discharge. The rotating motor 106 controls the rotating rod 105 to drive the sealing circular plate 104 to rotate. The sealing circular plate 104 fits the inner wall of the sandwich ring 103 to form a seal and rotates to open the channel for discharge operation.

The fixed plate 15 drives the upper cover 4 to open the inside of the reactor 1, which is convenient for operators to inspect and maintain the stirring blades 13 and the inside of the reactor 1. A large amount of impurities will be generated during the oil production process and need to be cleaned regularly. The cleaning mechanism fixedly installed on the upper end of the upper cover 4 is activated to clean the inside of the reactor 1. The cleaning mechanism does not require excessive manual intervention and effectively reduces the labor intensity, avoiding manual contact with toxic substances and gases. In the sealed state, the sealing plug plate 17 on the upper surface of the upper cover 4 is in a fixed state, and is limited by a pin 19 that penetrates the limiting round rod 18 on one side to avoid problems such as uneven mixing caused by the entry of air and impurities during the mixing process.

The turboprop 207 is rotatably mounted on the lower end of the limit support 206, and the lower end of the turboprop 207 is equipped with a rotating ring 208 through a fixed support arm 209. The rotating ring 208 is rotatably mounted on the lower end of the water pipe 201, and the lower surface of the rotating ring 208 is meshed with one end of the rotating head 204.
