Description

Technical Field

[0001] The utility model relates to the technical field of high-pressure homogenizers, in particular to a high-pressure homogenizer used for breaking the cell walls of microorganisms. Background Art

[0002] In the field of microorganisms, high-pressure homogenizers are also called microbial high-pressure wall breakers or microbial cell breakers. Because the cell structure of microorganisms is relatively hard, conventional mechanical crushing methods or enzymatic hydrolysis methods often cannot break the cell wall well. High-pressure homogenizers can break the cell wall under high pressure according to the characteristics of microbial cell structure, thereby extracting intracellular materials. High-pressure homogenizers for microbial cell wall breaking mainly include high-pressure pumps, processing chambers, filters, and other parts.

[0003] Publication No. CN 220345639 U discloses a high-pressure homogenizer, which increases the cleanliness of the top of the filter screen, reduces the problem of impurities accumulating in the middle of the filter screen after long-term use due to the fixed setting of the filter screen, causing difficulty in cleaning and clogging, improves the accuracy of the filter screen in cleaning impurities inside liquid materials, reduces the need for staff to frequently clean the middle of the filter screen, and reduces the labor intensity of staff.

[0004] When the high-pressure homogenizer of the prior art is used, the filter is adjusted to a tilted state and then cleaned. However, some impurities will be stuck in the filter and some impurities will adhere to the filter. When the filter is only adjusted to a tilted state and then cleaned, the impurities stuck in the filter and adhered to the filter cannot be effectively cleaned and some impurities are still difficult to clean.

[0027] Reference Figure 1-Figure 5 , which is an embodiment of the utility model, provides a high-pressure homogenizer for breaking the cell wall of microorganisms, which includes: a main unit 100 and a filter unit 200;

[0028] The main unit 100 includes a high-pressure homogenizer body 101, a feed pipe 102 is installed on the high-pressure homogenizer body 101, a guide pipe 103 is slidably connected in the feed pipe 102, a storage tube 104 is fixed on the top of the high-pressure homogenizer body 101, and a storage box 105 is placed in the storage tube 104;

[0029] The filter unit 200 includes an annular plate 201 fixed to the middle of the guide tube 103, a disc 203 is arranged in the middle of the annular plate 201, and a plurality of scrapers 202 are fixed at equal intervals along the radial direction of the outer side of the disc 203, and the end of the scraper 202 away from the disc 203 is fixed to the inner wall of the annular plate 201, a filter screen 204 is arranged in the guide tube 103, and the filter screen 204 is located below the annular plate 201, and a cleaning component 207 for cleaning impurities above the filter screen 204 is arranged in the guide tube 103.

[0030] When in use, the mixed liquid containing microorganisms is poured into the guide tube 103, so that the filter net 204 in the guide tube 103 filters the mixed liquid containing microorganisms to prevent impurities from being injected into the high-pressure homogenizer body 101, so that the high-pressure homogenizer body 101 can better break the wall of the microorganisms.

[0031] In addition, a disc 205 is fixed in the middle of the filter 204, and an annular plate 206 is fixed on the outside of the filter 204. When the top of the annular plate 206 fits with the bottom of the annular plate 1 201, the top of the filter 204 fits with the bottom of the scraper 202. An annular sleeve 209 is provided in the guide tube 103, and the annular sleeve 209 is located below the filter 204. A plurality of connecting rods 208 are fixed at equal intervals along the radial direction of the annular sleeve 209 on the outside, and one end of the connecting rod 208 away from the annular sleeve 209 is fixed to the inner wall of the guide tube 103. The cleaning assembly 207 includes A hollow column 2072 is rotatably connected to the annular sleeve 209 through an embedded bearing, a cylindrical rod 2071 is fixed to the bottom of the disk 205, and the cylindrical rod 2071 is movably inserted into the hollow column 2072. A pressure plate 2073 is fixed to the outside of the cylindrical rod 2071, and the pressure plate 2073 is slidably fitted in the hollow column 2072. A spring 2074 is sleeved on the outside of the cylindrical rod 2071, and one end of the spring 2074 is against the pressure plate 2073, and the other end of the spring 2074 is against the inner wall of the hollow column 2072. A lever 2075 is fixed to the bottom of the cylindrical rod 2071.

[0032] It should be noted that the cylindrical rod 2071 movably passes through the hollow column 2072 means that the cylindrical rod 2071 can rotate in the hollow column 2072 and can also slide in the hollow column 2072 .

[0033] During use, when it is necessary to clean the impurities on the filter screen 204, first move the guide tube 103 upward to remove the guide tube 103 from the feed tube 102, then take out the storage box 105 in the storage tube 104 and place the storage box 105 into the feed tube 102, then flip the guide tube 103 180°, and then move the guide tube 103 downward so that the guide tube 103 and the storage box 105 are covered, and then rotate the lever 2075 to drive the cylindrical rod 2071 to rotate, thereby driving the filter screen 204 to rotate, so that the scraper 202 drops the impurities on the filter screen 204 into the storage box 105.

[0034] In addition, two ear plates 106 are fixed on the top of the feed pipe 102, and a limiting rod 109 is slidably connected inside the two ear plates 106, and a connecting plate 107 is fixed on the top of the limiting rod 109. A rotating rod 108 is fixed on the side where the two connecting plates 107 are close to each other, and the ends of the two rotating rods 108 close to each other penetrate the guide pipe 103 and are rotatably connected to the guide pipe 103, and a baffle 110 is fixed at the bottom of the limiting rod 109.

[0035] When in use, for some impurities stuck in the filter 204 and some impurities adhering to the filter 204 that cannot be scraped off by the scraper 202, the lever 2075 is pulled to drive the cylindrical rod 2071, the pressure plate 2073, the filter 204, and the annular plate 206 to move. When the pressure plate 2073 moves, it will compress the spring 2074, and then the lever 2075 is released. At this time, the annular plate 206 and the filter 204 are driven to move under the rebound force of the spring 2074. When the annular plate 206 hits the annular plate 1 201, it will drive the filter 204 to vibrate, so that the impurities stuck in the filter 204 and some impurities adhering to the filter 204 are shaken off into the storage box 105.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
