DETAILED DESCRIPTION
[0016] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.
[0017] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present 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.
[0018] Cleaning devices for centrifugal extractors, such as Figure 1 and Figure 2 As shown, the lower end face of the vertically placed extraction cylinder 3 is fixed on the fixed base 1 through the turntable 2, that is, the extraction cylinder 3 can rotate relative to the fixed base 1, and a plurality of hoop rings 4 are sleeved on the side end face of the extraction cylinder 3, and the extraction cylinder 3 is slidably connected to the hoop ring 4 through the annular protrusion, so that the extraction cylinder 3 can rotate relative to the hoop ring 4, and the outer end faces of the plurality of hoop rings 4 are fixed on the vertically placed support rod 5, and the lower end face of the support rod 5 is fixedly connected to the fixed base 1, and a plurality of fastening bolts 10 passing through the thread are arranged on the hoop ring 4;
[0019] A rotating motor 7 is provided above the extraction cylinder 3, and the rotating motor 7 is fixedly connected to a plurality of supporting rods 5 in a circular shape through a horizontally placed connecting rod 6, and the motor shaft of the rotating motor 7 is fixedly connected to a stirring shaft 311 on a stirring device 31 in the extraction cylinder 3, and the upper end of the stirring shaft 311 passes through the upper end surface of the extraction cylinder 3 through a bearing, and a plurality of telescopic fixing devices 8 in a circular shape are fixedly provided on the upper end surface of the extraction cylinder 3;
[0020] The telescopic rod 81 on the telescopic fixing device 8 is fixed on the extraction cylinder 3, and the fastening bolt B82 passes through the upper end of the telescopic rod 81 through a thread;
[0021] like Figure 1 and Figure 2 As shown, a plurality of hoops 4 are provided with openings on the same vertical line, and two vertically placed electric slide rails 91 are provided at the openings. A transmission type strong magnetic block 92 provided on the electric slide rail 91 is slidably connected to the electric slide rail 91 through two electric sliders, and a strong magnetic block 93 adsorbed by magnetic force to the transmission type strong magnetic block 92 is located in the extraction cylinder 3. Figure 2 The extraction cylinder 3 is removed, so the strong magnetic block 93 is not directly adsorbed on the transmission type strong magnetic block 92, and the scraper 94 arranged on the strong magnetic block 93 abuts against the inner wall of the extraction cylinder 3;
[0022] In order to ensure that the scraper 94 always abuts against the inner wall of the extraction cylinder 3, the end face of the strong magnetic block 94 to which the scraper 94 is fixed has a strong magnetic force, while the other end faces do not have a strong magnetic force.
[0023] When the extraction cylinder 3 needs to be cleaned internally, the fixing device 8 is first shortened, and then one end of the fastening bolt B82 is fastened to the stirring shaft 311 of the stirring device 31, so that the stirring device 31 is fixed to the extraction cylinder 3, and then the fastening bolt 10 on the hoop 4 is screwed out of the hoop 4, so that the extraction cylinder 3 can be rotated in the horizontal direction relative to the hoop 4 and the fixed base 1 in principle;
[0024] At this time, the rotating motor 7 is started. Since the rotating motor 7 is fixedly connected to the support rod 5 through the connecting rod 6, the rotating motor 7 is fixed through the support rod 5. Therefore, when the rotating motor 7 is started this time, the rotating motor 7 will drive the extraction cylinder 3 to rotate while driving the stirring device 31 to rotate. When the extraction cylinder 3 rotates, the electric slide rail 91 is started at this time, so that the transmission type strong magnetic block 92 on the lifting type cleaning scraper 9 moves up and down on the electric slide rail 91. Since the transmission type strong magnetic block 92 and the strong magnetic block 93 located in the extraction cylinder 3 are adsorbed by magnetic force, that is, the strong magnetic block 93 is adsorbed on the inner wall of the extraction cylinder 3, and since the scraper 94 is provided on the strong magnetic block 93, that is, the scraper 94 directly abuts against the extraction cylinder 3, when the transmission type strong magnetic block 92 moves up and down on the electric slide rail 91, the strong magnetic block 92 is moved up and down on the electric slide rail 91. When the extraction cylinder 3 is in motion, the scraper 94 in the extraction cylinder 3 will be driven to move up and down, and the extraction cylinder 3 is rotating, and the scraper 94 is lifted and lowered, and the scraper 94 can scrape off the residue on the inner wall of the extraction cylinder 3 in cooperation with the cleaning agent and cleaning liquid entering into the extraction cylinder 3, and the scraped residue will settle in the extraction cylinder 3. At this time, the fastening bolt B82 on the telescopic fixing device 8 is unscrewed to extend the telescopic rod 81, and then the fastening bolt B82 is fastened to the rotating motor 7, and then the fastening bolt 10 is screwed into the hoop 4, and then the extraction cylinder 3 is fixed on the hoop 4. At this time, the rotating motor 7 is started, and the stirring device 31 can be rotated relative to the extraction cylinder 3. At this time, the cleaning water continues to enter from the liquid inlet, and the residue can be discharged from the liquid outlet of the extraction cylinder 3, so that the extraction cylinder 3 is cleaned.
[0025] When the extraction cylinder 3 is in use, the extraction cylinder 3 and the rotary motor 7 are fixed together, so that the stirring device 31 can be rotated relative to the extraction cylinder 3 to achieve centrifugal extraction.
[0026] In this solution, the liquid separation outlet A and the liquid separation outlet B located at the upper end of the extraction cylinder 3 are both located below the top end surface of the extraction cylinder 3, and the upper end surface of the electric slide rail 91 is located above the liquid separation outlet A and the liquid separation outlet B, so that when the extraction cylinder 3 is extracting and separating, the strong magnetic block 93 and the scraper 94 located inside the extraction cylinder 3 will not be affected by the stirring device 31 stirring and separating the liquid.
[0027] The above description is only an explanation of the preferred embodiments of the present application and the technical principles and other schemes used. At the same time, the scope of the invention involved in the present application is not limited to the technical scheme formed by a specific combination of the above technical features, but also should cover other technical schemes formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the above features are replaced with the technical features with similar functions disclosed in the present application (but not limited to) by each other to form a technical scheme.
