Description

Technical Field

[0001] The utility model relates to amino acid production, and more particularly to a decolorization and filtering device with a replaceable decolorizer used in amino acid production. Background Art

[0002] Amino acids are a class of amphoteric organic compounds containing basic amino groups and acidic carboxyl groups, and are the basic building blocks of biological functional macromolecular proteins.

[0003] Amino acids have a wide range of uses, including but not limited to the food industry, medicine, feed industry, chemical industry, agriculture and cosmetics.

[0004] There are many different amino acid production processes, primarily categorized into two: chemical synthesis and microbial fermentation. For various reasons, the intermediate liquid products formed during amino acid production contain pigments. Failure to remove these pigments can severely impact the quality of the final product. Therefore, decolorization is a crucial step in amino acid production.

[0005] In the prior art, the filtering part of the decolorization filter device is fixedly installed in the decolorization filter device, and the manufacturing enterprise can only purchase the decolorization filter device as a whole from the equipment manufacturer. When the decolorization filter agent in the decolorization filter device is saturated with adsorption, the adsorption function of the decolorization filter agent can only be restored by desorption. During the desorption process, on the one hand, the decolorization filter device cannot continue to produce during desorption, and on the other hand, the decolorization filter device must meet the process requirements of desorption, resulting in higher requirements for the decolorization filter device.

[0006] Moreover, when the decolorizing filter has been used for a long time, it becomes more difficult or impossible to recover the decolorizing filter by desorption, and the manufacturer can only continue production by replacing the decolorizing filter device. Utility Model Content

Figure 2 This is a structural diagram of a decolorizing filter agent feeding device provided by the utility model. Figure 3 This is a structural schematic diagram of another decolorizing filter agent feeding device provided by the utility model.

[0031] A decolorization and filtering device with replaceable decolorizing agents for amino acid production comprises a tank cover 2, a tank wall 3 and a tank bottom 4, wherein the tank cover 2, the tank wall 3 and the tank bottom 4 form a cavity 1, the tank cover 2 is provided with an intermediate liquid product feed port 5, the tank bottom 4 is provided with a decolorized liquid discharge port 6, a removable upper orifice plate 7 and a removable lower orifice plate 8 are provided in the cavity 1, and the removable upper orifice plate 7 and the removable lower orifice plate 8 divide the cavity 1 into an upper cavity 9, a middle cavity 10 and a lower cavity 11, a decolorization filter inlet 12 is provided on the tank wall 3 above the removable upper orifice plate 7, and the decolorization filter inlet 12 is connected to a decolorization filter feeding device 13.

[0032] By arranging a removable upper orifice plate 7 and a removable lower orifice plate 8, as well as a decolorizing filter inlet 12 and a decolorizing filter feeding device 13 in the cavity 1, before production, the removable lower orifice plate 8 is first installed, and then the decolorizing filter is fed into the cavity 10 through the decolorizing filter feeding device 13 from the decolorizing filter inlet 12. When the decolorizing filter fills the middle cavity 10, the removable upper orifice plate 7 is installed, forming a decolorizing filter layer in the cavity 1. Then, the intermediate liquid product is introduced from the intermediate liquid product feeding port 5 to perform decolorization adsorption. After the decolorizing filter layer is saturated with adsorption, production is stopped, the tank lid 2 is opened, and the removable upper orifice plate 7 is removed, the saturated decolorizing filter is removed, and the unadsorbed decolorizing filter is reloaded to restart production. The removed saturated decolorizing filter is desorbed by a special desorption device and reused. When the decolorizing filter completely loses its adsorption function, only the decolorizing filter needs to be replaced, and the entire decolorizing filter device does not need to be replaced.

[0033] Those skilled in the art should know that the aperture of the detachable lower perforated plate 8 is smaller than the particle size of the decolorizing filter to prevent the decolorizing filter from falling through the aperture of the detachable lower perforated plate 8 .

[0034] In one or more specific embodiments, the decolorizing filter agent is activated carbon.

[0035] In one or more specific embodiments, an upper supporting block 15 and a lower supporting block 16 are respectively provided on the tank wall 3.

The fasteners can be bolts, studs, or other fasteners that can be disassembled, and are not particularly limited here.

[0036] In one or more specific embodiments, in order to make the decolorization filter agent height of the decolorization filter layer as uniform as possible and to increase the loading speed, two intermediate liquid product feed ports 5 and two decolorization filter agent feeding devices 13 are provided.

[0037] In one or more specific embodiments, the decolorizing filter agent feeding device 13 includes a silo 131, a discharge pipe 132, a feeding pipe 133, a spiral 134 and a rotating power mechanism 135. The spiral 134 is installed in the feeding pipe 133. One end of the discharge pipe 132 is connected to the silo 131, and the other end is connected to the feeding pipe 133. The spiral 134 passes through the feeding pipe 133 and is connected to the output shaft of the rotating power mechanism 135. The end of the feeding pipe 133 away from the output shaft is connected to the intermediate liquid product feed port 5.

[0038] In one or more specific embodiments, the rotational power mechanism 135 is preferably a motor.

[0039] Those skilled in the art should know that the cooperation between the rotating power mechanism 135 and the screw 134 to convey materials is an existing technology.

[0040] In one or more other specific embodiments of the present invention, in order to reduce the shearing and squeezing of the decolorizing filter during transportation, the feed pipe axis 136 is located above the spiral axis 137 to achieve an eccentric configuration, and an upper gap between the feed pipe 133 and the spiral 134 is larger than the lower gap, thereby reducing the shearing and squeezing of the decolorizing filter.

[0041] In one or more specific embodiments, the minimum gap of the lower gap is not less than 2.5 times the maximum decolorizing filter particle size.

[0042] In one or more specific embodiments, to facilitate removal of saturated decolorizing filter from the decolorizing filter feed device, a pumping rod 17 is further provided within the chamber 1. The pumping rod 17 passes through the removable upper orifice plate 7 and the removable lower orifice plate 8. When the pumping rod 17 is inserted, the pumping rod 17 forms a seal with the removable upper orifice plate 7 and the removable lower orifice plate 8. When the pumping rod 17 is withdrawn, the decolorizing filter falls through the large hole in the removable lower orifice plate 8 for the pumping rod 17 to pass through, and then leaves the device through the decolorized liquid discharge port 6.

[0043] In one or more specific embodiments, in order to facilitate the extraction of the extraction rod 17 , a handle is provided at the top end of the extraction rod 17 .

[0044] In one or more specific embodiments, the decolorization and filtration device with replaceable decolorizing agent for amino acid production is further provided with support legs 14 , which are connected to the tank bottom 4 for supporting the entire device.

[0045] In one or more specific embodiments, the tank cover 2 can be a flat cover or a semicircular cover, and the tank bottom 5 can be a flat bottom or a conical bottom. Those skilled in the art can make the selection according to their needs.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
