Description

Technical Field

[0001] The utility model relates to the technical field of medicinal material preparation, in particular to an ultrafiltration tank for extracting traditional Chinese medicine components. Background Technique

[0002] After retrieving the patent document with the announcement number CN215085291U, the driving mechanism drives the sliding rod to rotate and the slider to move. Through the movement of the slider, the mounting part, the filter cloth and the scraper are driven to move towards the recovery bucket. When the filter cloth falls off, the filter residue enters the recovery bucket. At the same time, as the scraper moves, the medicinal residues remaining at one end of the filter cloth near the gap are pushed into the slag recovery bucket by the filter cloth.

[0003] When cleaning the filter residue, since the movement of the scraper and the filter cloth will cause the filter cloth to enter the recovery bucket, and as the filter cloth moves, it will fold. The folded filter cloth will wrap the filter residue. During this process, some filter residues will detach from the filter cloth. At the same time, the filter cloth will also fold when it enters the recovery bucket, which will cause it to be more troublesome to clean the filter residue on the filter cloth. Even if most of the filter residue on the filter cloth is cleaned, there will still be some filter residue attached to the filter cloth, and then it needs to be cleaned again before it can be used.

[0031] The present utility model will be further described below with reference to the accompanying drawings:

[0032] As Figures 1 - 8 shown, an ultrafiltration tank for extracting traditional Chinese medicine components includes a tank body 1. A feed pipe 2 is fixed to the upper side of the tank body 1, and a feed valve 3 is fixed to the upper end of the feed pipe 2. A discharge pipe 4 is fixed to the lower side of the tank body 1, and a discharge valve 5 is fixed to the lower end of the discharge pipe 4. It further includes a slag discharging mechanism 6 for filtering traditional Chinese medicine and extruding the slag and an ultrafiltration mechanism 7 for re-filtering the filtered traditional Chinese medicine.

[0033] In this embodiment: The slag discharging mechanism 6 includes a bracket 62. A pressing cylinder 61 is fixed to the top of the bracket 62. A pressure rod 63 is slidably connected inside the bracket 62. A circular pressing plate is fixed to the lower end of the pressure rod 63. A spiral guiding strip is arranged on the outer side of the pressure rod 63. A rotating sleeve 64 is sleeved on the pressure rod 63 at the position of the guiding strip. A guiding groove 66 for facilitating the passing of the guiding strip is formed inside the rotating sleeve 64. Three scraper frames 65 are circumferentially distributed on the outer side of the rotating sleeve 64. A filter cover 67 is arranged on the lower side of the scraper frame 65. A closing mechanism 8 for supporting when extruding the traditional Chinese medicine slag is arranged at the lower end of the filter cover 67. The filter cover 67 is welded by a conical hopper and an annular cylinder. Filter holes for filtering the traditional Chinese medicine slag are formed on both the conical hopper and the annular cylinder. The lower end of the pressing cylinder 61 is fixed to the top of the tank body 1. The inner diameter of the circular pressing plate of the pressure rod 63 is the same as that of the annular cylinder of the filter cover 67. The telescopic part of the pressing cylinder 61 is used to push the pressure rod 63 to move downward, so that the scraper frame 65 of the rotating sleeve 64 abuts against the conical hopper of the filter cover 67. At the same time, through the cooperation of the guiding strip of the pressure rod 63 and the guiding groove 66 of the rotating sleeve 64, the rotating sleeve 64 is made to drive the scraper frame 65 to rotate inside the conical cover of the filter cover 67, and then the traditional Chinese medicine slag filtered by the conical hopper is scraped into the annular cylinder of the filter cover 67 by the scraper frame 65. Then, as the pressure rod 63 continues to move downward, the circular pressing plate enters the filter cover 67 to extrude and filter the traditional Chinese medicine slag, so as to squeeze out the medicinal liquid adsorbed in the traditional Chinese medicine slag.

[0034] In this embodiment: the ultrafiltration mechanism 7 includes a conical partition 73, which is fixed in the middle position inside the tank body 1, and an ultrafiltration partition frame 71 is arranged at the lower side of the conical partition 73. A plurality of ultrafiltration membranes 72 for filtering traditional Chinese medicine are nested inside the ultrafiltration partition frame 71. The conical bucket of the filter cover 67 is located on the upper side of the conical partition 73, and the annular cylinder of the filter cover 67 is located on the inner side of the ultrafiltration partition frame 71. The conical partition 73 is used to introduce the medicinal liquid filtered by the conical bucket of the filter cover 67 into the inner side of the ultrafiltration partition frame 71. At the same time, the medicinal liquid squeezed in the annular cylinder of the filter cover 67 also enters the inner side of the ultrafiltration partition frame 71, and then the medicinal liquid is ultrafiltered through the ultrafiltration membrane 72.

[0035] In this embodiment: the closing mechanism 8 includes a fixed frame 81 and a protruding column 83 which are symmetrically arranged. The fixed frame 81 and the protruding column 83 are both located at the bottom of the tank body 1. The fixed frame 81 is rotatably connected with a closing seat 82 for closing the lower end of the tank body 1. The protruding column 83 is rotatably connected with a rotating plate 84 for locking the position of the closing seat 82. The fixed frame 81 is fixedly connected to the tank body 1, and the protruding column 83 is fixedly connected to the tank body 1. After the Chinese medicine residue is squeezed and filtered, the rotating plate 84 on the protruding column 83 is rotated to separate it from the support of the closing seat 82, and then the closing seat 82 will flip downward with the fixed frame 81 as the center, and then the bottom of the tank body 1 will be opened and the Chinese medicine residue will be pushed out.

[0036] Working principle: When in use, firstly, the Chinese medicine to be filtered is fed into the tank body 1 through the feed valve 3 and the feed pipe 2, and the Chinese medicine is filtered through the filter cover 67 inside the tank body 1, and then the filtered liquid medicine enters the inner side of the ultrafiltration partition frame 71, at which time the Chinese medicine is filtered through the ultrafiltration membrane 72, and the liquid medicine after ultrafiltration enters the outer side of the ultrafiltration partition frame 71, at which time the discharge valve 5 can be opened to send the liquid medicine after ultrafiltration to the outside through the discharge pipe 4;

[0037] After the Chinese medicine is filtered, Chinese medicine residue will be attached to the filter cover 67, and then the telescopic part of the extrusion cylinder 61 pushes the pressure rod 63 to move downward, so that the scraper frame 65 of the rotating sleeve 64 is against the conical bucket of the filter cover 67, and at the same time, the guide bar of the pressure rod 63 cooperates with the guide groove 66 of the rotating sleeve 64, so that the rotating sleeve 64 drives the scraper frame 65 to rotate in the conical cover of the filter cover 67. At this time, the rotating scraper frame 65 scrapes the Chinese medicine residue filtered by the conical bucket into the annular cylinder of the filter cover 67 for concentration, and then as the pressure rod 63 continues to move downward, the circular pressure plate enters the filter cover 67 to squeeze and filter the Chinese medicine residue, so that the medicinal liquid adsorbed in the Chinese medicine residue is squeezed out and flows into the ultrafiltration partition frame 71 again for ultrafiltration discharge;

[0038] After the liquid medicine in the Chinese medicine residue is completely squeezed out, the rotating plate 84 on the rotating boss 83 is rotated to make it separate from the support of the closing seat 82, and then the closing seat 82 will turn downward with the fixing frame 81 as the center, and then the bottom of the tank body 1 will be opened and the Chinese medicine residue will be pushed out.

[0039] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
