Description

Technical Field

[0001] This utility model relates to the field of solvent oil processing technology, specifically to a solvent oil dehydration device. Background Technology

[0002] Solvent oil is one of the five major categories of petroleum products. Solvent oil has a wide range of applications. The largest user is paint solvent oil (commonly known as oil for paint coatings), followed by edible oils, printing inks, leather, pesticides, insecticides, rubber, cosmetics, fragrances, pharmaceuticals, and electronic components.

[0003] Currently, in the production process of solvent oil, it is necessary to dehydrate the solvent oil through a dehydration device. Conventional solvent oil dehydration devices mostly heat the solvent oil in the tank by electric heating tubes. However, the heating temperature is uneven, and some water vapor in the solvent oil cannot evaporate, resulting in poor dehydration effect. In addition, the heated solvent oil contains a lot of heat, which is wasted by discharging the dehydrated solvent oil. Therefore, we propose a solvent oil dehydration device to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a solvent oil dehydration device, which solves the problems mentioned in the background section.

The oil inlet pipe is fixedly installed at the lower edge of the left side wall of the tank and is equipped with a check valve. A first oil discharge mechanism of the tank is connected to the preheating mechanism. A second oil discharge mechanism is fixedly installed at the right edge of the preheating mechanism. A vacuum assembly is fixedly installed on the left side of the upper surface of the tank. Liquid distribution boxes are fixedly installed on both the upper surface and the lower inner wall of the tank, and a heat exchange mechanism is fixedly installed between the upper and lower liquid distribution boxes.

A control mechanism is provided on the right side of the tank.

[0009] Furthermore, the preheating mechanism includes a housing and a preheating pipe. The preheating pipe is fixedly installed on the left and right inner walls of the housing, and the lower end of the preheating pipe extends out of the left side of the left side wall of the housing. The liquid outlet of the preheating pipe is connected to the oil inlet pipe.

[0010] Furthermore, the first oil discharge mechanism includes an oil outlet pipe and a solenoid valve. The oil outlet pipe connects the tank body to the box body, and the solenoid valve is installed on the oil outlet pipe.

[0011] Furthermore, the second oil discharge mechanism has the same structure as the first oil discharge mechanism.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0023] like Figures 1-3 As shown in the figure, an embodiment of the present invention discloses a solvent oil dehydration device, including a tank body 1. A preheating mechanism 2 is fixedly installed on the lower surface of the tank body 1 and is connected to an oil inlet pipe 3. The oil inlet pipe 3 is fixedly installed at the lower edge of the left side wall of the tank body 1 and is equipped with a check valve 4. A first oil discharge mechanism 5 of the tank body 1 is connected to the preheating mechanism 2. A second oil discharge mechanism 6 is fixedly installed at the right edge of the preheating mechanism 2. A vacuum assembly 7 is fixedly installed on the left side of the upper surface of the tank body 1. Liquid distribution boxes 8 are fixedly installed on both the upper surface and the lower inner wall of the tank body 1, and a heat exchange mechanism 9 is fixedly installed between the upper and lower liquid distribution boxes 8. A motor 10 is fixedly installed on the upper surface of the liquid distribution box 8, and a heating mechanism 11 is installed between the upper and lower liquid distribution boxes 8. A control mechanism 12 is provided on the right side of the tank body 1.

[0024] like Figure 2 As shown, in some embodiments, the preheating mechanism 2 includes a housing 201 and a preheating pipe 202. The preheating pipe 202 is fixedly installed on the left and right inner walls of the housing 201, and the lower end of the preheating pipe 202 extends out of the left side of the left side wall of the housing 201. The liquid outlet of the preheating pipe 202 is connected to the oil inlet pipe 3.

[0025] In this embodiment, the box 201 is used to store the dehydrated high-temperature solvent oil, and the preheating pipe 202 is used for the subsequent solvent oil that needs to be dehydrated to flow in, so that the high-temperature solvent oil in the box 201 preheats the subsequent solvent oil that needs to be dehydrated.

[0026] like Figure 1 As shown, in some embodiments, the first oil discharge mechanism 5 includes an oil outlet pipe 501 and a solenoid valve 502. The oil outlet pipe 501 connects the tank 1 to the box 201, and the solenoid valve 502 is installed on the oil outlet pipe 501.

[0027] In this embodiment, the solenoid valve 502 is opened, allowing the solvent oil in the tank 1 to flow into the box 201.

[0028] like Figure 1 and Figure 2 As shown, in some embodiments, the second oil discharge mechanism 6 has the same structure as the first oil discharge mechanism 5.

[0029] In this embodiment, the second oil discharge mechanism 6 allows solvent oil to flow out of the tank 201.

[0030] like Figure 3 As shown, in some embodiments, the heat exchange mechanism 9 includes a mechanical seal 901, a transmission pipe 902, a liquid inlet 903, a liquid distribution pipe 904, and a heat exchange pipe 905. The transmission pipe 902 is installed on the upper and lower side walls of the liquid distribution box 8 through the mechanical seal 901, and the transmission pipe 902 is provided with a liquid inlet 903 on the front side wall inside the liquid distribution box 8. The liquid distribution pipe 904 is fixedly installed on the transmission pipe 902, and the heat exchange pipe 905 is evenly fixedly installed between the upper and lower liquid distribution pipes 904.

[0031] In this embodiment, the heating oil in the upper liquid distribution tank 8 flows into the upper transmission pipe 902 through the upper liquid inlet 903 and rotates, then flows into the liquid distribution pipe 904 through the upper transmission pipe 902 and into the heat exchange pipe 905 through the liquid distribution pipe 904. The heat exchange pipe 905 heats the solvent oil in the tank 1. The heated oil after heat exchange in the heat exchange pipe 905 flows into the lower liquid distribution tank 8 through the lower liquid distribution pipe 904, transmission pipe 902 and liquid inlet 903. The upper transmission pipe 902 rotates with the output shaft of the motor 10, so that the transmission pipe 902 drives the heat exchange pipe 905 to rotate through the liquid distribution pipe 904, thereby making the heat exchange pipe 905 stir the solvent oil.

[0032] like Figure 2 As shown, in some embodiments, the heating mechanism 11 includes an extraction component 111, an electric heating box 112, and a conduit 113. The extraction component 111 is installed on the right side of the tank body 1. The inlet and outlet of the extraction component 111 are respectively connected to the lower liquid distribution box 8 and the electric heating box 112. The electric heating box 112 is connected to the upper liquid distribution box 8 through the conduit 113.

[0033] In this embodiment, the extraction component 111 extracts the heating oil from the lower liquid distribution tank 8 into the electric heating box 112, and heats the heating oil through the electric heating box 112. The heated oil then flows into the upper liquid distribution tank 8 through the conduit 113.

[0034] like Figure 2 As shown, in some embodiments, the control mechanism 12 includes a controller 121, a temperature controller 122, and a liquid level sensor 123. The controller 121 is installed on the right side of the tank 1, and the temperature controller 122 is embedded on the right side wall of the tank 1 corresponding to the controller 121. The liquid level sensor 123 is installed on the left inner wall of the tank 1.

[0035] In this embodiment, the controller 121 controls the opening and closing of each electrical component, and the temperature controller 122 monitors the temperature of the solvent oil in the tank 1, thereby controlling the heating temperature of the electric heating box 112. The liquid level sensor 123 monitors the amount of solvent oil added in the tank 1.

[0036] In use, the external solvent oil requiring dehydration is pumped into the preheating pipe 202 of the preheating mechanism 2 by a booster pump. The solvent oil in the tank 201, after being dehydrated at high temperature, preheats the solvent oil in the preheating pipe 202. The preheated solvent oil flows into the tank 1 through the oil inlet pipe 3. The liquid level of the solvent oil is monitored by the liquid level sensor 123 in the control mechanism 12. When the set liquid level is reached, the booster pump stops pumping oil, the second oil discharge mechanism 6 opens, and the dehydrated solvent oil in the tank 201 is discharged. Then the second oil discharge mechanism 6 is closed, and the heating oil in the lower distribution tank 8 is drawn into the electric heating box 112 by the extraction component 111 in the heating mechanism 11. The heating oil is heated by the electric heating box 112, and the heated oil flows into the upper distribution tank 8 through the conduit 113. The heated oil in the upper distribution tank 8 flows into the upper transmission pipe 902 through the upper inlet hole 903 and rotates. The solvent oil flows into the distribution pipe 904 and then into the heat exchange pipe 905. The heat exchange pipe 905 heats the solvent oil in the tank 1. The heated solvent oil then flows into the lower distribution box 8 through the lower distribution pipe 904, the transmission pipe 902, and the inlet hole 903. The upper transmission pipe 902 rotates with the output shaft of the motor 10, causing the transmission pipe 902 to drive the heat exchange pipe 905 to rotate through the distribution pipe 904. This stirs the solvent oil in the heat exchange pipe 905, ensuring that the solvent oil in the tank 1 is heated evenly and that the water vapor in the solvent oil evaporates completely, resulting in better dehydration. After dehydration, the solenoid valve 502 in the first oil discharge mechanism 5 opens, allowing the solvent oil in the tank 1 to flow into the box 201 through the oil outlet pipe 501 for subsequent preheating. After oil discharge, the solenoid valve 502 closes, reducing heating time, improving production efficiency, and lowering operating costs.

[0037] In summary, the solvent oil dehydration device, through the heat exchange mechanism 9, enables the solvent oil in the tank 1 to be heated sufficiently and evenly, allowing the water vapor in the solvent oil to evaporate fully, thereby improving the dehydration effect of the solvent oil. Furthermore, the high-temperature solvent oil after dehydration increases the preheating of the solvent oil that needs to be dehydrated later, reducing heating time, improving production efficiency, and reducing usage costs.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
