A paraffin oil decoloring tank

Abstract

This utility model discloses a paraffin oil decolorizing tank, including a decolorizing tank and a filter box. The decolorizing tank has a manhole at the top and a liquid outlet at the bottom. The tank is divided into an upper chamber and a lower chamber by an inclined partition. The highest point of the inclined partition has a connecting port for linking the upper and lower chambers, with a filter screen and gate valve on the connecting port. The lowest point of the inclined partition is connected to a discharge pipe, which connects to the filter box. The filter box is connected to the lower chamber via a liquid delivery pipe. This paraffin oil decolorizing tank, through the sedimentation and separation of the paraffin oil and bleaching clay mixture by the inclined partition, discharges most of the paraffin oil, requiring only filtration of the remaining mixture. This reduces the flow rate for filtration and impurity removal, improves work efficiency, and reduces overall production time.

Technical Field

[0001] This utility model relates to a paraffin oil decolorizing tank. Background Technology

[0002] In the waste oil recycling industry, paraffin oil needs to be decolorized and impurity removed. Quartz sand is commonly used in the industry as an adsorption and purification material to decolorize and remove impurities from paraffin oil, thereby improving oil quality and reducing production costs. Existing decolorization tanks are widely used for decolorization, purification, and impurity removal of paraffin oil. However, existing decolorization tanks have low working efficiency, which affects the overall production time. Summary of the Invention

[0003] The purpose of this utility model is to provide a paraffin oil decolorizing tank, including a decolorizing tank and a filter box. The decolorizing tank has a manhole at the top and a liquid outlet at the bottom. The decolorizing tank is divided into an upper cavity and a lower cavity by an inclined partition. The highest point of the inclined partition has a connecting port for connecting the upper cavity and the lower cavity. The connecting port is equipped with a filter screen and a gate valve. The lowest point of the inclined partition is connected to a discharge pipe, which is connected to the filter box. The filter box is connected to the lower cavity through a liquid delivery pipe.

[0004] Preferably, the upper cavity is provided with a stirring device, which includes a motor, a rotating shaft and a stirring rod. The motor is located at the top of the decolorization tank, and the output end of the motor is connected to the rotating shaft extending into the interior of the upper cavity. The stirring rod is located on the rotating shaft.

[0005] Preferably, the discharge pipe is detachably connected to one side of the filter box, the infusion pipe is detachably connected to the other side of the filter box, and a filter screen layer is provided inside the filter box.

[0006] Preferably, both the discharge pipe and the infusion pipe are equipped with valves.

[0007] Preferably, both the decolorizing tank and the filter box are provided with an insulation layer.

[0008] The advantages and beneficial effects of this utility model are as follows: It provides a paraffin oil decolorization tank, in which the paraffin oil and bleaching clay mixture are separated by sedimentation through the inclined baffle inside the decolorization tank, and most of the paraffin oil is discharged. Only the remaining mixture needs to be filtered, which reduces the flow rate for filtration and impurity removal, improves work efficiency, and reduces the overall production time. Attached Figure Description

[0009] Figure 1 This is a schematic diagram of the present invention. Detailed Implementation

[0010] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0011] The specific technical solution of this utility model is as follows: like Figure 1 As shown, a paraffin oil decolorizing tank includes a decolorizing tank 1 and a filter box 2. The decolorizing tank 1 has a manhole 3 at the top and a liquid outlet 4 at the bottom. The decolorizing tank 1 is divided into an upper cavity 6 and a lower cavity 7 by an inclined partition 5. The highest point of the inclined partition 5 has a connecting port 8 for connecting the upper cavity 6 and the lower cavity 7. The connecting port 8 is equipped with a filter screen 9 and a gate valve 10. The lowest point of the inclined partition 5 is connected to a discharge pipe 11, which is connected to the filter box 2. The filter box 2 is connected to the lower cavity 7 by a liquid delivery pipe 12.

[0012] The upper cavity 6 is equipped with a stirring device 14, which includes a motor 141, a rotating shaft 142, and a stirring rod 143. The motor 141 is located at the top of the decolorizing tank 1, and the output end of the motor 141 is connected to the rotating shaft 142 and extends into the interior of the upper cavity 6. The stirring rod 143 is located on the rotating shaft 142. Specifically, the stirring device 14 is used to stir and mix the activated clay so that it can be evenly dispersed in the paraffin oil.

[0013] The filter box 2 is detachably connected to the discharge pipe 11 on one side and to the infusion pipe 12 on the other side. The filter box 2 is provided with a filter screen layer 21. Specifically, both sides of the filter box 2 are provided with threaded openings 22. One end of the discharge pipe 11 is threaded to the threaded opening 22 on one side of the filter box 2, and one end of the infusion pipe 12 is threaded to the threaded opening 22 on the other side of the filter box 2, thereby realizing the detachable replacement operation of the filter box 2.

[0014] Both the discharge pipe 11 and the infusion pipe 12 are equipped with valves 13.

[0015] Both the decolorizing tank 1 and the filter box 2 mentioned above are equipped with a heat insulation cotton layer on the outside.

[0016] When in use, open the manhole 3, add the paraffin oil to be decolorized into the decolorization tank 1, then add the activated clay into the paraffin oil in the decolorization tank 1 in proportion, close the manhole 3, start the motor 141, the motor 141 drives the stirring rod 143 to rotate through the rotating shaft 142, and the stirring device 14 stirs and mixes so that the activated clay can be evenly dispersed in the paraffin oil. Afterwards, the motor 141 is turned off. During the settling process of the paraffin oil and bleaching clay mixture, impurities are adsorbed and separated by the activated bleaching clay. After the mixture of paraffin oil and bleaching clay is separated by the inclined baffle 5, the gate valve 10 of the connecting port 8 is opened. Most of the paraffin oil enters the lower cavity 7 from the connecting port 8 at the highest point of the inclined baffle 5. Then, the valves 13 on the discharge pipe 11 and the infusion pipe 12 are opened. The remaining mixture enters the filter box 2 through the discharge pipe 11 at the lowest point. The remaining paraffin oil is fed into the lower cavity 7 through the infusion pipe 12 after passing through the filter screen layer 21. The paraffin oil decolorization tank of this utility model reduces the flow rate of filtration and impurity removal, improves work efficiency, and reduces the overall production time.

[0017] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
