[0002] In animal feed, saccharin sodium can be used as a sweetener to improve the taste of feed, thereby increasing the appetite and feed intake of animals. Before using saccharin sodium as an animal feed additive, it is crucial to ensure its purity. The purification process can remove impurities, ensure the quality of the final product, and avoid adverse effects on animal health.

[0003] In the prior art, the production of sodium saccharin is usually completed by liquid precipitation. When sodium saccharin crystallizes, it needs to be scraped off from the inner wall of the crystallization tank with the help of a scraper. However, since a small amount of liquid is usually attached to the crystal surface, the sodium saccharin crystals are easily adhered to the scraper surface after being scraped off. Long-term adhesion may cause damage to the scraper, thereby affecting its normal use effect. Therefore, it is necessary to propose a crystallization collection device for saccharin sodium purification processing to address the above problems. Summary of the invention

[0010] Preferably, the ends of the two groups of connecting rods are fixedly connected to limiting blocks, and the radius of the limiting blocks is larger than the radius of the connecting rods.

[0011] Preferably, a spring is sleeved on the outer wall of the connecting rod, one end of the spring is fixedly connected to the guide rail, and the other end of the spring is fixedly connected to the limit block.

[0012] Preferably, the upper end surface of the crystallization tank is rotatably connected with two sets of transmission wheels, the two sets of transmission wheels are respectively coaxially fixedly connected to the slide rod and the reciprocating screw, and the two sets of transmission wheels are connected to each other through a transmission belt.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figure 1-5 A crystal collection device for purifying sodium saccharin comprises a crystallization tank 1, wherein a feed pipe 2 and a discharge pipe 4 are respectively installed at the upper end and the lower end of the crystallization tank 1, wherein the feed pipe 2 and the discharge pipe 4 are both connected to the inside of the crystallization tank 1, a scraper 7 is slidably connected in the crystallization tank 1, a slide bar 11 is rotatably connected to the top of the crystallization tank 1, a guide groove 12 is provided on the side wall of the slide bar 11, a guide rail 13 is slidably connected in the guide groove 12, a cleaning plate 14 is installed on the outer wall of the guide rail 13, the cross-sectional shape of the scraper 7 and the cleaning plate 14 at the connection with the cleaning plate 14 are both triangular, and a drive scraper 7 is installed in the crystallization tank 1 to slide. The driving mechanism; by means of the up and down sliding of the scraper 7, the crystals attached to the inner wall of the crystallization tank 1 can be scraped off, and by means of the rotation of the slide bar 11, the cleaning plate 14 can be driven to slide along the outer wall of the scraper 7, and the crystals attached to the outer wall can be scraped off during sliding, and the shape of the junction between the outer wall of the scraper 7 and the cleaning plate 14 is triangular, and the inclined surface of the triangle helps to reduce the adhesion of the crystals, and the crystals are more likely to slide naturally under the action of gravity to avoid accumulation on the surface of the scraper 7 or the cleaning plate 14, and the sliding of the scraper 7 can synchronously drive the guide rail 13 to move in the guide groove 12.

[0025] The driving mechanism includes a reciprocating screw 8 rotatably connected to the crystallizer 1, a screw sleeve 10 is threadedly connected to the threaded section of the reciprocating screw 8, the screw sleeve 10 is fixedly connected to the scraper 7, a limit rod 9 is fixedly connected in the crystallizer 1, the screw sleeve 10 is slidably connected to the outer wall of the limit rod 9, and two groups of connecting rods 15 are slidably connected to the end of the guide rail 13, the ends of the two groups of connecting rods 15 are fixedly connected to the cleaning plate 14, and the ends of the two groups of connecting rods 15 are fixedly connected to the limit blocks 16, the radius size of the limit blocks 16 is larger than the radius size of the connecting rods 15, and the outer wall sleeve of the connecting rod 15 is provided with a spring 17, one end of the spring 17 is fixedly connected to the guide rail 13, and the other end of the spring 17 is fixedly connected to the limit block 16; with the help of the elastic force of the spring 17 itself, when driving the cleaning plate 14 to slide on the outer wall of the scraper 7, the two can be in close contact, thereby improving the effect of cleaning the outer wall of the scraper 7.

[0026] The upper end surface of the crystallization tank 1 is rotatably connected with two sets of transmission wheels 5, which are respectively coaxially fixedly connected to the slide rod 11 and the reciprocating screw 8, and the two sets of transmission wheels 5 are connected to each other through a transmission belt 6. A servo motor 3 is fixedly connected to the upper end of the crystallization tank 1, and the end of the output shaft of the servo motor 3 is coaxially fixedly connected to the adjacent transmission wheel 5.

[0027] In the present invention, the device is specifically used as follows: first, a saccharin sodium solution is input into a crystallization tank 1 through a feed pipe 2. After the solution enters the tank, crystallization begins by cooling or other means to form saccharin sodium crystals, which are attached to the inner wall of the crystallization tank 1. When the saccharin sodium crystals are formed on the inner wall of the crystallization tank 1, a servo motor 3 is started to drive a transmission wheel 5 to rotate, and power is transmitted to a reciprocating screw 8 through a transmission belt 6, which then drives a scraper 7 to slide up and down along the inner wall of the crystallization tank 1. During the sliding process of the scraper 7 up and down, the saccharin sodium crystals attached to the tank wall are scraped off.

[0028] The slide bar 11 is also driven by the servo motor 3 to rotate through the transmission wheel 5. When the slide bar 11 rotates, the guide rail 13 rotates accordingly, driving the cleaning plate 14 to slide along the outer wall of the scraper 7. The sliding of the cleaning plate 14 can effectively scrape off the sodium saccharin crystals attached to the surface of the scraper 7, avoiding the crystals from sticking to the scraper 7 for a long time.

[0029] The joint between the scraper 7 and the cleaning plate 14 is designed to be triangular. The inclined surface of the triangle can reduce the adhesion of saccharin sodium crystals. Under the action of gravity, the crystals are more likely to slide off the surfaces of the scraper 7 and the cleaning plate 14, avoiding the accumulation of crystals on the surface and improving the cleaning effect. When the scraper 7 slides up and down, the guide rail 13 slides synchronously in the guide groove 12 to ensure that the sliding of the scraper 7 and the cleaning action of the cleaning plate 14 remain coordinated. The elastic force of the spring 17 ensures that the cleaning plate 14 and the scraper 7 surface are in close contact, thereby improving the cleaning effect.

[0030] With the continuous operation of the scraper 7 and the cleaning plate 14, the scraped sodium saccharin crystals are gradually deposited at the bottom of the crystallization tank 1. When enough crystals are collected, the discharge pipe 4 is opened to discharge the crystals and send them to the subsequent processing steps.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
