Description

Technical Field

[0001] This utility model relates to the technical field of demulsifier mixing equipment, specifically to a demulsifier mixing tank. Background Technology

[0002] In systems such as crude oil and chemical wastewater, oil and water form a stable emulsion, requiring demulsifiers to solve the problem of oil and water separation. As surfactants, demulsifiers adsorb onto the interface between oil and water droplets, disrupting the originally stable emulsion film and breaking down the oil-water emulsion system. This allows the previously mixed oil and water to separate rapidly, and they are mainly used in oil fields, chemical plants, and environmental protection applications.

[0003] When preparing demulsifiers, it is generally necessary to use a stirred tank to uniformly and quickly blend various raw materials. For example, Chinese utility model patent with patent publication number CN215939696U discloses an enamel stirred tank for crude oil demulsifier. The stirred tank is equipped with a tank body, and a screw is coaxially rotated inside the tank body. A stirring mechanism is threaded on the outside of the screw. The stirring mechanism can be controlled to move up and down by driving the screw to rotate, thereby ensuring that the raw materials at the bottom of the tank body can be uniformly mixed.

[0004] However, in actual operation, the threaded connector on the screw of the aforementioned enamel-lined mixing vessel will cause wear on the surface of the screw, and the screw immersed in the raw material will be corroded, which will reduce the operational stability and service life of the mixing vessel.

[0019] In an exemplary implementation, such as Figures 1-5 As shown, this embodiment provides a demulsifier mixing vessel, including a vessel body 100, an inlet / outlet pipe assembly 200, a stirring element 300, a gear set 400, and a motor 500. The stirring element 300 is coaxially rotatably disposed inside the vessel body 100 and is used to stir the raw materials. The gear set 400 is installed on the top of the vessel body 100 and connected to the top of the stirring element 300. The gear set 400 is used to make the stirring elements 300 stir in opposite directions. The motor 500 is installed at the bottom of the vessel body 100 and is used to drive the stirring element 300 to stir the raw materials.

[0020] In this embodiment, the raw material is injected into the vessel body 100 through the inlet / outlet pipe assembly 200. The motor 500 is started, and the motor 500 drives the stirring component 300 to rotate, thereby stirring the raw material in the vessel body 100. At the same time, the top of the stirring component 300 is connected to the gear set 400 and transmits power to it. The gear set 400 can then guide the stirring component 300 to rotate in opposite directions, thereby improving the stirring efficiency and effect. In other words, this stirring vessel avoids the situation where parts with mechanical wear risks are immersed in the raw material.

[0021] In one embodiment, please refer to Figure 1 The inlet and outlet pipe assembly 200 includes an inlet pipe 210 and an outlet pipe 220 respectively installed at the top and bottom of the vessel body 100.

[0022] In this embodiment, the feed pipe 210 and the discharge pipe 220 are connected to the feeding equipment and the storage equipment, respectively.

[0023] In one embodiment, please refer to Figures 1-5 The stirring component 300 includes a rotating shaft 310 coaxially mounted inside the vessel body 100 and a rotating sleeve 320 sleeved on the upper half of the outer side of the rotating shaft 310. Stirring blades 330 are evenly distributed on the outside of the rotating shaft 310 and the rotating sleeve 320. The two ends of the rotating shaft 310 extend to the outside of the top and bottom ends of the vessel body 100, respectively. The gear set 400 and the motor 500 are respectively connected to the top and bottom ends of the rotating shaft 310.

[0024] In this embodiment, the motor 500 is started, and the motor 500 drives the rotating shaft 310 to rotate. The rotation of the rotating shaft 310 can drive the external stirring blades 330 to rotate, thereby stirring the raw materials inside the vessel body 100. At the same time, the top of the rotating shaft 310 is connected to the gear set 400, and the gear set 400 can transmit power to the rotating sleeve 320, so that the rotating sleeve 320 and the external stirring blades 330 rotate together.

[0025] Please refer to Figure 2 and Figure 3 The bottom outer side of the rotating shaft 310 and the top outer side of the rotating sleeve 320 are both fixedly fitted with scraper 340 that contacts the inner wall of the vessel body 100. The scraper 340 can scrape the inner wall of the vessel body 100 to prevent material from sticking. The two scraper 340 are rotatably connected to the inner wall of the vessel body 100 at their close ends to ensure the stability of rotation.

[0026] Furthermore, the "round cover" part on the top of the vessel body 100 is detachable and can be removed together with the rotating sleeve 320 to facilitate subsequent maintenance operations. This is common knowledge and is not specifically shown in the figure.

[0027] In one embodiment, please refer to Figures 2-4The gear set 400 includes an internal gear ring 410 fixedly installed on the top of the rotating shaft 310 and a first gear 420 fixedly sleeved on the top of the rotating sleeve 320. Several second gears 430 rotatably installed on the top of the vessel body 100 are uniformly meshed between the internal gear ring 410 and the first gear 420. The output shaft of the motor 500 is fixedly connected to the bottom end of the rotating shaft 310.

[0028] In this embodiment, the bottom of the internal gear ring 410 forms an upward recess to accommodate the first gear 420 and the second gear 430, and the inner ring teeth on the edge of the internal gear ring 410 can mesh with the second gear 430. Specifically, when the rotating shaft 310 rotates, it can drive the internal gear ring 410 to rotate. The rotation of the internal gear ring 410 can mesh with and drive several second gears 430 to rotate, and then drive the first gear 420 on the top of the rotating sleeve 320 to rotate through the meshing of the second gears 430. At this time, the rotating sleeve 320 and the rotating shaft 310 rotate in opposite directions.

[0029] Please refer to Figure 1 The internal gear ring 410, the first gear 420 and the second gear 430 are all fitted with the same protective cover 600 which is fixedly connected to the top of the vessel body 100. The protective cover 600 can improve the safety of this stirring vessel.

[0030] In one embodiment, please refer to Figures 1-3 The vessel body 100 is covered by an outer jacket 700 and a medium pipe 710 with a spiral disc disposed between the inner wall of the outer jacket 700 and the outer wall of the vessel body 100.

[0031] In this embodiment, the two ends of the medium tube 710 extend to the outside of the vessel body 100 and are connected to the temperature control device, thereby facilitating the control of the temperature of the vessel body 100 and ensuring the mixing rate.

[0032] Finally, all parts of this device that should have sealing components are equipped with corresponding sealing structures, such as O-rings and back rings, which are existing technologies and will not be described in detail.

[0033] To better understand this utility model, the following is combined with... Figures 1 to 5The technical solution of this utility model is described in detail as follows: In use, the raw material is injected into the vessel body 100 through the feed pipe 210. The motor 500 is started, and the motor 500 drives the rotating shaft 310 to rotate. The rotation of the rotating shaft 310 drives the external stirring blades 330 to rotate, thereby stirring the raw material inside the vessel body 100. At the same time, the rotation of the rotating shaft 310 drives the internal gear ring 410 to rotate. The rotation of the internal gear ring 410 meshes with and drives several second gears 430 to rotate. The rotation of the second gears 430 meshes with and drives the first gear 420 on the top of the rotating sleeve 320 to rotate, so that the rotating sleeve 320 and the external stirring blades 330 rotate together. At this time, the rotating sleeve 320 and the rotating shaft 310 rotate in opposite directions, which improves the stirring efficiency and effect. That is, this stirring vessel avoids the situation where parts with mechanical wear risks are immersed in the raw material.

[0034] In summary, this utility model solves the technical problem of easy corrosion of mechanically worn parts when immersed in raw materials by using a motor 500 and a gear set 400 at both ends of the stirring component 300. This achieves the technical effect of reducing the risk of corrosion and contamination and improving work efficiency.
