Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal extractors, in particular to a liquid pretreatment device for centrifugal extractors. Background Art

[0002] Classical extraction involves bringing a solution into close contact with an immiscible solvent, allowing one or more solutes in the solution to enter the solvent and thereby separate them from other interfering substances in the solution. Extraction separation has been used in analytical applications since a very early time. Extraction technology originated with the extraction, separation, and purification of nuclear fuel and has been widely used in chemical, metallurgical, pharmaceutical, biological, and aerospace industries. During the use of a centrifugal extractor, if a certain amount of impurities and sediment accumulates inside the centrifuge pipes, even if the pipes do not clog the centrifuge, the centrifuge separation effect will still be poor, resulting in a lack of separation between the inside and the outside. Furthermore, over time, this can cause the centrifuge pipes to become clogged, requiring cleaning and unblocking of the pipes. This requires professional operation and maintenance, resulting in high subsequent maintenance costs for the centrifuge extractor. Utility Model Content

[0003] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide a liquid pretreatment device for a centrifugal extractor.

[0004] According to the technical solution provided in the embodiment of the present application, the feed liquid pretreatment device for the centrifugal extractor includes a connecting pipe, the upper end of which is fixedly connected to the feed liquid bent pipe through an adjustable connecting rod A and an adjustable connecting rod B. After the feed liquid bent pipe passes through the adjustable connecting rod A and the adjustable connecting rod B and moves away from the connecting pipe, the filter screen between the feed liquid bent pipe and the connecting pipe is replaced by rotating the rotating filter screen replacement device on the adjustable connecting rod A.

[0005] Furthermore, the adjustable connecting rod A includes an upper telescopic rod A and a lower telescopic rod A. The upper telescopic rod A is movably inserted into the lower telescopic rod A. The outer end surface of the lower telescopic rod A is threaded with a bolt A. The upper end surface of the bolt A is connected to a connecting plate A fixedly sleeved on the upper telescopic rod A through an adjustable compression spring A. The lower end surface of the bolt A is connected to a rotating filter replacement device movably sleeved on the lower telescopic rod A through a movable compression spring A. A limit plate A is fixedly provided on the lower telescopic rod A for limiting the rotating filter replacement device.

[0006] Furthermore, the rotary filter screen replacement device includes an annular seat and a replacement ring. The annular seat is movably sleeved on the lower telescopic rod A, and the replacement ring is fixedly connected to the annular seat through a connecting rod, so that the replacement ring rotates under the rotation of the annular seat.

[0007] Furthermore, the upper and lower end surfaces of the bolt A are provided with an annular turntable for rotationally connecting with the adjustable compression spring A and the movable compression spring A, thereby facilitating the rotation of the bolt A and allowing the bolt A to move up or down during the rotation process.

[0008] Furthermore, a sealing ring placement groove is provided on the inner end surface of the replacement ring to facilitate the placement of the sealing ring and the filter screen.

[0009] Furthermore, the adjustable connecting rod B includes an upper telescopic rod B and a lower telescopic rod B. The upper telescopic rod B is movably inserted into the lower telescopic rod B. The outer end surface of the lower telescopic rod B is threaded with a bolt B. The upper end surface of the bolt B is connected to a connecting plate B fixedly sleeved on the upper telescopic rod B through an adjustable compression spring B. The upper end surface of the bolt B is rotatably connected to the adjustable compression spring B through a ring-shaped turntable to realize the extension and retraction of the adjustable connecting rod B.

[0010] To sum up, the beneficial effects of the present application are as follows: the device of the present application is a pipeline for facilitating the replacement of the filter screen, and is used on the liquid inlet or outlet pipeline of the centrifugal extractor, thereby reducing the probability of impurity deposition inside the pipeline of the centrifugal extractor, thereby reducing the subsequent maintenance costs of the separation extractor; the device of the present application uses an adjusting rod to adjust the distance between the two sections of the pipeline, and then replaces the filter screen by rotating the filter screen replacement device, which is easy to operate.

It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant invention and are not intended to limit the invention. It should also be noted that, for ease of description, only portions relevant to the invention are shown in the accompanying drawings.

[0018] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0019] Centrifugal extractor liquid pretreatment device, such as Figure 1 and Figure 2 As shown, the lower end of the connecting pipe 1 is provided with a connecting thread, and the upper portion thereof is fixedly connected to the liquid elbow 4 via the adjustable connecting rod A2 and the adjustable connecting rod B3. The filter screen replacement device 5 which can rotate relative to the adjustable connecting rod A2 is movably sleeved on the adjustable connecting rod A2;

[0020] like Figure 3 As shown, the upper telescopic rod A21 on the adjustable connecting rod A2 is movably inserted into the lower telescopic rod A22, and the outer end surface of the lower telescopic rod A22 is threaded with a bolt A23, and the upper and lower end surfaces of the bolt A23 are fixedly provided with an annular turntable that can rotate in the horizontal plane. The upper and lower end surfaces of the bolt A23 are respectively fixedly connected to the adjustable compression spring A24 and the movable compression spring A26 through the annular turntable, the upper end surface of the adjustable compression spring A24 is fixedly connected to the connecting disk A25 fixedly sleeved on the upper telescopic rod A21, and the lower end surface of the movable compression spring A26 is fixedly connected to the rotary filter screen replacing device 5 movably sleeved on the lower telescopic rod A22, and the movable compression spring A26 can rotate relative to the rotary filter screen replacing device 5, that is, the upper end surface of the rotary filter screen replacing device 5 is provided with an annular turntable that rotates in the horizontal plane, and the movable compression spring A26 is fixedly connected through the annular turntable;

[0021] The presence of the limit plate A27 prevents the rotary filter screen replacement device 5 from descending to a position below its replacement ring 52, causing the replacement ring 52 to tilt and affecting its installation effect.

[0022] like Figure 3 As shown, the annular seat 51 on the rotary filter replacement device 5 is movably mounted on the lower telescopic rod A22, and a limit plate A27 is fixedly provided on the lower telescopic rod A22 below the annular seat 51. The end surfaces of the annular seat 51 are fixedly connected to the annular replacement ring 52 via connecting rods 53, and the inner end surface of the replacement ring 52 is provided with a sealing ring placement groove concentric with the replacement ring 52.

[0023] like Figure 4As shown, the upper telescopic rod B31 on the adjustable connecting rod B3 is movably inserted into the lower telescopic rod B32, and the outer end surface of the lower telescopic rod B32 is threaded with a bolt B33. The upper end surface of the bolt B33 is provided with an annular turntable that can rotate on a horizontal plane. The annular turntable is connected to and fixedly sleeved on the connecting disk B35 on the upper telescopic rod B31 through an adjustable compression spring B34.

[0024] When in use, the device is screwed to the pipeline of the centrifugal extractor through the connecting pipe 1, and then the liquid elbow 4 is suspended at one end and connected to the infusion hose;

[0025] When the filter screen needs to be replaced, the bolts A23 and B33 on the adjustable connecting rod A2 and the adjustable connecting rod B3 connecting the connecting pipe 1 and the liquid bend 4 are rotated to make the liquid bend 4 move upward relative to the connecting pipe 1. At this time, the annular seat 51 on the rotary filter screen replacement device 5 on the lower telescopic rod A22 is connected to the bolt A23 through the movable compression spring A26, so the annular seat 51 will move upward with the replacement ring 52 between the connecting pipe 1 and the liquid bend 4, that is, the replacement ring 52 will rise relative to the connecting pipe 1. At this time, there is a gap between the connecting pipe 1 and the liquid bend 4, which can be opened by Rotate the annular seat 51 to rotate the filter screen inside the replacement ring 52 out of the pipeline. After the replacement ring 52 rotates the filter screen inside it out of the pipeline, the filter screen and the sealing ring inside the replacement ring 52 can be replaced. After the replacement is completed, rotate the annular seat 51 again so that the replaced filter screen and the sealing ring are rotated together with the replacement ring 52 to between the connecting pipe 1 and the liquid bend pipe 4. At this time, rotate the bolts A23 and B33 in the opposite direction to move the bolts A23 and B33 downward. At this time, the liquid bend pipe 4 can be pressed down onto the connecting pipe 1 until the connecting pipe 1 and the liquid bend pipe 4 are tightly connected.

[0026] Steps for placing the filter screen in the replacement ring 51: first place the sealing ring in the sealing ring placement groove on the inner end face of the replacement ring 51. At this time, the inner end face diameter of the sealing ring will be smaller than the inner end face diameter of the replacement ring 51. At this time, place the filter screen with the same outer diameter as the inner diameter of the replacement ring 51 in the replacement ring 51 above the sealing ring.

[0027] In actual application, the outer diameter of the replacement ring 51 is the same as the outer diameter of the connecting pipe 1, and a connecting groove is provided at the upper end of the connecting pipe 1. Similarly, a connecting groove is also provided at the lower end of the liquid bend 4. The connecting gap between the connecting pipe 1 and the liquid bend 4 is sealed by a sealing ring to prevent the liquid from overflowing.
