Description

Technical Field:

[0001] The utility model relates to the technical field of pharmaceutical processing equipment, and particularly relates to a spermine filtering device. Background Art:

[0002] O, O-dimethylthiophosphoramide, also known as spermine or spermidine, is a kind of polyamine, a polyamine substance containing two amino groups and two imino groups, and is a biologically active low-molecular-weight aliphatic nitrogen-containing base produced in the process of biological metabolism. The content of spermine in organisms is not high, but it is a regulatory substance necessary for microorganisms, animals and humans to synthesize nucleic acids and proteins.

[0003] Its preparation method is to carry out amination using methyl chloride as the raw material. During the preparation process, the liquid material (crude spermine) needs to be allowed to stand and layer. The oil layer is the crude spermine product, which is then subjected to evaporation crystallization, further filtration, and finally a spermine solution is obtained. Finally, the finished spermine is obtained through dehydration treatment.

[0004] The current technical defect is that after standing and layering, the obtained crude spermine contains salts and mechanical impurities, and usually needs to be filtered. Usually, the crude spermine at a temperature of 90 - 95 °C (spermine can penetrate the filter bag or ultrafiltration membrane within this temperature range) is stored in a bottomed tank for precipitation for 3 - 7 days, and then the spermine solution is filtered through a filter bag, leaving the salts and other impurities remaining in the spermine solution in the filter bag to complete the filtration. The filtration time is relatively long, affecting the production efficiency.

[0005] Therefore, a new technical solution is proposed to shorten the filtration time and improve the production efficiency. Content of the Utility Model:

[0009] Inside the tank, a first partition board, a second partition board and an ultrafiltration membrane are fixedly arranged in sequence from top to bottom, so that a primary filtration chamber, a buffer chamber, a secondary filtration chamber and a collection chamber are formed from top to bottom inside the tank. A cover is installed on the top of the tank, and a pressure gauge and an air inlet pipe are installed on the cover. A plurality of uniformly distributed threaded through holes are formed in the first partition board, and filter cartridges corresponding to the number of the threaded through holes are arranged on the upper surface of the first partition board.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-5 , the present invention provides a technical solution for a spermine filtration device:

[0022] A spermine filtration device includes a tank body 1, a first partition board 2, a second partition board 3, an ultrafiltration membrane 4, a sealing cover 5, a pressure gauge 6, an inlet pipe 7, a filter cartridge 8, a filter element 9, a first liquid inlet pipe 10, a first liquid discharge pipe 11, a connecting pipe 12, a second liquid inlet pipe 13, a second liquid discharge pipe 14, a T-shaped three-way ball valve 15, a third liquid discharge pipe 16 and a water inlet pipe 17;

[0023] Inside the tank body 1, a first partition board 2, a second partition board 3 and an ultrafiltration membrane 4 are fixedly installed in sequence from top to bottom, so that a primary filtration chamber 1.1, a buffer chamber 1.2, a secondary filtration chamber 1.3 and a collection chamber 1.4 are formed inside the tank body 1 from top to bottom. A sealing cover 5 is installed on the top of the tank body 1, and a pressure gauge 6 and an inlet pipe 7 are installed on the sealing cover 5. The inlet pipe 7 is connected to an external booster pump.

[0024] A plurality of uniformly distributed threaded through holes 2.1 are formed in the first partition plate 2. The upper surface of the first partition plate 2 is provided with filter cartridges 8 corresponding to the number of the threaded through holes 2.1. The bottom end of the filter cartridge 8 is provided with an external thread 8.1. The bottom end of the filter cartridge 8 is threadedly connected to the threaded through hole 2.1. A filter element 9 is sleeved inside the filter cartridge 8. The filter cartridge 8 mainly plays a role in supporting and fixing the filter element 9, and at the same time allows the liquid material to flow into the filter element 9 through the filter cartridge 8. A first liquid inlet pipe 10 and a first liquid discharge pipe 11 are respectively installed at the top and bottom of the primary filtration chamber 1.1. The first liquid discharge pipe 11 is mainly used during backwashing; a connecting pipe 12 is installed at the bottom of the buffer chamber 1.2. A second liquid inlet pipe 13 and a second liquid discharge pipe 14 are respectively installed at the top and bottom of the secondary filtration chamber 1.3. The second liquid discharge pipe 14 is used during flushing. The connecting pipe 12 and the second liquid inlet pipe 13 are connected through a T-shaped three-way ball valve 15. A water inlet pipe 17 is also connected to the T-shaped three-way ball valve 15. A third liquid discharge pipe 16 is installed at the bottom of the collection chamber 1.4.

[0025] Stop valves are installed on the first liquid inlet pipe 10, the first liquid discharge pipe 11, the connecting pipe 12, the second liquid inlet pipe 13, the second liquid discharge pipe 14 and the third liquid discharge pipe 16 to block the flow of liquid.

[0026] The working principle is as follows: When filtering, first close the stop valves on the first liquid discharge pipe 11 and the second liquid discharge pipe 14, open the stop valve on the third liquid discharge pipe 16, and control the T-shaped three-way ball valve 15 to connect the connecting pipe 12 and the second liquid inlet pipe 13.

[0027] Subsequently, spermine solution is introduced, and the booster pump is turned on to inject air pressure into the tank body 1 to increase the pressure inside the tank body 1, so that the spermine solution entering the tank body 1 quickly passes through the filter cartridge 8 and enters the filter element 9 for two-stage filtration. The filtered spermine solution flows into the buffer chamber 1.2 along with the filter element 9, and then flows into the secondary filtration chamber 1.3 through the connecting pipe 12 and the second liquid inlet pipe 13. The spermine solution in the secondary filtration chamber 1.3 is subjected to a third-stage filtration by the ultrafiltration membrane 4, so that the salts and other impurities remaining in the spermine solution are left in the secondary filtration chamber 1.3, and the qualified spermine solution flows into the collection chamber 1.4 and is discharged through the third liquid discharge pipe 16 at the bottom of the collection chamber 1.4 and sent to the spermine storage tank for subsequent dehydration treatment.

[0028] After using for a certain period of time, in order to extend the service life of the device, cleaning is required. During the cleaning process, the booster pump is not turned on. First, the stop valves on the first liquid inlet pipe 10 and the second liquid discharge pipe 14 need to be closed, and the T-shaped three-way ball valve 15 is controlled to connect the connecting pipe 12 and the water inlet pipe 17, so that water flows into the buffer chamber 1.2 under the action of water pressure and enters the filter element 9 along the threaded through hole 2.1, and flows into the primary filtration chamber 1.1, so that the particulate matter attached to the filter element 9 or the filter cartridge 8 is backwashed off and discharged through the first liquid discharge pipe 11 on the primary filtration chamber 1.1. After the water is clear, immediately close the stop valve on the first liquid discharge pipe 11, open the stop valve on the second liquid discharge pipe 14, and at the same time control the T-shaped three-way ball valve 15 to connect the second liquid inlet pipe 13 and the water inlet pipe 17, so that water flows into the secondary filtration chamber 1.3 under the action of water pressure, and the salt and other impurities attached to the ultrafiltration membrane 4 are washed off and discharged along the second liquid discharge pipe 14. After the water is clear, control the T-shaped three-way ball valve 15 to connect the connecting pipe 12 and the second liquid inlet pipe 13, and close the water inlet pipe 17 so that the residual water in the buffer chamber 1.2 flows into the secondary filtration chamber 1.3 and is discharged along the second liquid discharge pipe 14 to complete the cleaning work.

[0029] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
