[0019] Specifically, please refer to Figure 1 and Figure 2 , Figure 1 is the schematic diagram of the overall cross-sectional structure of the decolorization device for vegetable oil provided by the embodiment of the present application, Figure 2 is Figure 1Enlarged view at A. The decolorization device 100 for vegetable oil includes a mixing tank 110 and a buffer tank 120. In the mixing tank 110, crude oil and clay are added in a certain proportion, and the proportion can be 100:1. The buffer tank 120 is used to temporarily store the decolorized vegetable oil and can inject the vegetable oil into the corresponding storage tank. A stirring device is arranged in the mixing tank 110, and the stirring device is used to stir the crude oil and clay so that the two are quickly and evenly mixed. The top of the mixing tank 110 is connected with a first feeding pipe 111 and a second feeding pipe 112, and the first feeding pipe 111 and the second feeding pipe 112 are respectively used to add crude oil and clay into the stirring device. A negative pressure pump 113 is arranged on the mixing tank 110. The input end of the negative pressure pump 113 is connected to the inner cavity of the mixing tank 110. The end of the negative pressure pump 113 is connected with a first shunt pipe 114 and a second shunt pipe 115 through a three-way valve. The negative pressure pump 113 is used to pump the crude oil and clay in the mixing tank 110 to two impurity removal cylinders 130 through the first shunt pipe 114 and the second shunt pipe 115 respectively for impurity removal. Specifically, the two impurity removal cylinders 130 can be used alternately by adjusting the three-way valve. When one of the impurity removal cylinders 130 is performing the impurity removal operation, the other impurity removal cylinder 130 can be cleaned and replaced. The other ends of the first shunt pipe 114 and the second shunt pipe 115 are respectively connected with the impurity removal cylinders 130. Two positioning grooves 121 are arranged at the top of the buffer tank 120, and the two impurity removal cylinders 130 are installed in the positioning grooves 121. A sealing component 140 for connecting the impurity removal cylinder 130 and the positioning groove 121 is arranged between the impurity removal cylinder 130 and the positioning groove 121. The sealing component 140 can fix the impurity removal cylinder 130 inside the positioning groove 121 at the top of the buffer tank 120, so as to ensure the stability of the equipment during use. An opening is made at the center of the bottom of the positioning groove 121 and is connected to the inner cavity of the buffer tank 120. A plurality of filter meshes 131 are detachably arranged in the impurity removal cylinder 130. The clay and crude oil will be filtered through the filter meshes 131 to filter out the residues. The bottom wall of the impurity removal cylinder 130 is a mesh plate 132. The filtered vegetable oil will flow into the buffer tank 120 through the mesh plate 132. An oil outlet pipe 122 is arranged at the bottom of the buffer tank 120. The buffer tank 120 is used to temporarily store a part of the vegetable oil, and at the same time, the vegetable oil in the buffer tank 120 can be exported through the oil outlet pipe 122 to the subsequent production process, such as a deodorization device, through an external device.

[0020] As can be seen from the above, in the embodiment of the present application, the buffer tank 120 is provided to temporarily store the filtered vegetable oil. At the same time, since two impurity removal cylinders 130 are provided at the top of the buffer tank 120, and the vegetable oil and clay in the mixing tank 110 can be pumped into the two impurity removal cylinders 130 respectively through the negative pressure pump 113, the first shunt pipe 114 and the second shunt pipe 115, the two impurity removal cylinders 130 can be used alternately. When one of the impurity removal cylinders 130 is working normally, the other impurity removal cylinder 130 can be disassembled from the bottom of the buffer tank 120 for replacement or cleaning. After the cleaning and replacement are completed, it can be assembled on the top of the buffer tank 120 again by using the sealing component 140. And in the embodiment of the present application, the two impurity removal cylinders 130 are both located at the top of the buffer tank 120. After the two impurity removal cylinders 130 are alternated, one of the impurity removal cylinders 130 performs the filtering task, while the residual vegetable oil in the other impurity removal cylinder 130 slowly falls into the buffer tank 120 under the action of gravity. After a period of time, the impurity removal cylinder 130 is cleaned, which can effectively avoid the waste of vegetable oil caused by the cleaning process.

[0021] In some embodiments, the sealing component 140 includes an annular support platform 141. The annular support platform 141 is arranged on the top of the buffer tank 120 and around the outer periphery of the positioning groove 121. A connecting ring 142 is arranged on the outer periphery of the middle part of the impurity removal cylinder 130. The connecting ring 142 abuts against the top of the annular support platform 141. A plurality of L-shaped rotating rods 143 are hinged on the outer side of the annular support platform 141. The other end of the L-shaped rotating rod 143 is screwed with a threaded rod 144. The bottom of the threaded rod 144 is connected with a pressing block 145 through a rotating joint. The pressing block 145 abuts against the top of the connecting ring 142. In the embodiment of the present application, a specific setting method of the sealing component 140 is shown. During the working process, when installing the impurity removal cylinder 130, the impurity removal cylinder 130 is inserted into the positioning groove 121. At this time, the connecting ring 142 will abut against the top of the annular support platform 141. Rotate the L-shaped rotating rod 143 so that the end of the L-shaped rotating rod 143 rotates to the top of the connecting ring 142. At this time, by rotating the threaded rod 144, the threaded rod 144 drives the pressing block 145 to fall. After the pressing block 145 falls, it will squeeze the connecting ring 142 downward. The connecting ring 142 and the annular support platform 141 will be closely attached, and at this time, the installation of the impurity removal cylinder 130 can be completed.

[0022] In some embodiments, a rubber sealing ring 150 is arranged at the bottom of the connecting ring 142. The rubber sealing ring 150 is located between the connecting ring 142 and the annular support platform 141. In the embodiment of the present application, by setting the rubber sealing ring 150, the sealing performance between the connecting ring 142 and the annular support platform 141 can be greatly enhanced.

[0023] In some embodiments, a funnel-shaped aggregate hopper 160 is provided at the bottom of the impurity removal cylinder 130. The top of the aggregate hopper 160 is hermetically arranged on the outer periphery of the mesh plate 132, and a grouting pipe 161 is formed at the bottom of the aggregate hopper 160. In the embodiments of the present application, by providing the aggregate hopper 160, the vegetable oil in the impurity removal cylinder 130 will sequentially fall into the buffer tank 120 through the aggregate hopper 160 and the grouting pipe 161 after filtration. On the other hand, when the impurity removal cylinder 130 is disassembled and cleaned, the impurity removal cylinder 130 can be inverted and a water pipe can be connected to the grouting pipe 161. At this time, clean water can be used to make the clean water enter the interior of the impurity removal cylinder 130 through the grouting pipe 161 to wash and clean it.

[0024] In some embodiments, it includes a liquid level sensor 170. The liquid level sensor 170 is connected to an alarm device. The detection end of the liquid level sensor 170 extends into the inner cavity of the buffer tank 120 and the horizontal height of the detection end of the liquid level sensor 170 is lower than the horizontal height of the bottom end of the impurity removal cylinder 130. In the embodiments of the present application, through the above settings, when the liquid level of the vegetable oil in the buffer tank 120 rises to a certain height and is detected by the liquid level sensor 170, an alarm can be given through the externally connected alarm device at this time to prompt the operator to complete the drainage operation of the vegetable oil in the buffer tank 120 as soon as possible.

[0025] In some embodiments, the impurity removal cylinder 130 is arranged in a frustum shape with a larger top and a smaller bottom. A plurality of groups of support protrusions 133 are arranged on the inner wall of the impurity removal cylinder 130, and the filter net 131 is supported on the support protrusions 133. In the embodiments of the present application, through the above settings, the plurality of filter nets 131 can further enhance the filtering effect. And because the impurity removal cylinder 130 is integrally arranged in a frustum shape with a larger top and a smaller bottom, the diameter of the filter net 131 will decrease sequentially from top to bottom. Therefore, when the filter net 131 needs to be taken out, since the diameter of the bottom filter net 131 is smaller than that of the top filter net 131, the support protrusion 133 at the top will not block the bottom filter net 131, which is convenient for taking out the bottom filter net 131.

[0026] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be covered within the scope of the claims and the description of the present application. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way.
