Description

Technical Field

[0001] The utility model belongs to the technical field of sodium alginate preparation, and particularly relates to a sodium alginate screening device. Background Art

[0002] Sodium alginate is a natural polysaccharide, which is currently used in the food industry and the pharmaceutical field. The preparation of sodium alginate requires first crushing the seaweed, then washing with water to remove impurities, extracting with strong alkaline water, and clarifying to obtain a crude alginate solution, which is then reacted with calcium chloride to obtain calcium alginate, which is then decolorized and deodorized and treated with acid to remove soluble impurities to obtain alginate precipitate, and finally reacted with sodium carbonate to obtain sodium alginate;

[0003] In the production process of sodium alginate, sodium alginate with different pore sizes needs to be screened out. Usually, a screening device is used for screening. In order to prevent sodium alginate from clogging the holes of the screen, the screening device often has a vibration function. In order to prevent sodium alginate from colliding with each other on the screen and falling, a circle of baffles will be set around the screen. However, this will also cause part of the sodium alginate to be stuck in the corner of the baffle. Sodium alginate that is not convenient to clean is stuck in the corner for a long time. When the temperature is suitable, it will cause deterioration and affect the subsequent screening work.

[0004] To this end, we proposed a sodium alginate screening device to solve the above problems. Utility Model Content

[0022] Reference Figure 2 The top wall of the card plate 5 and the top wall of the baffle 4 are sleeved with a card block 6, and the top wall of the card block 6 is fixedly connected with a bent rod 7. The main purpose of the bent rod 7 is to connect the card block 6 with the slider 9. The slider 9 is slidably connected in the vertical slot 8, and the end of the bent rod 7 away from the card block 6 is fixedly connected to the side wall of the slider 9. A plurality of vertical slots 8 are opened on the side wall of the fixed frame 2, and the number of the vertical slots 8 is twice the number of the screens 3. Two vertical slots 8 are respectively arranged at both ends of each screen 3, and the positions of the vertical slots 8 correspond to the positions of the screens 3. There is a vertical slot 8 on both sides of each screen 3.

[0023] Reference Figure 3 and Figure 4 The side wall of the slider 9 facing away from the curved rod 7 is provided with a driving mechanism for linking a plurality of sliders 9. The driving mechanism includes two connecting rods 10, a push rod 11, a push plate 12, a guide rod 13, a pull ring 14 and two plug rods 15. The connecting rod 10 is fixedly connected to the side walls of the two sliders 9 located on the same side of the screen 3. The longitudinal section of the connecting rod 10 is "U" shaped. The connecting rod 10 fixes the two sliders 9 on the same side together for easy simultaneous control. The push rod 11 is fixedly connected to the side walls of the two connecting rods 10 facing away from the slider 9. The side wall of the push rod 11 is provided with a through hole 16.
