DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0029] Embodiment one

[0030] As shown in Figures 1 to 8 A monosodium glutamate crystallization and separation device, which comprises a crystallization tank 1, a feed pipe 5 is communicated with the top surface of the crystallization tank 1, a sealing cover matched with the feed pipe 5 is threadedly connected to the surface of the feed pipe 5, a separation tank 2 is fixedly connected to the lower side of the crystallization tank 1 through a plurality of connecting supports, a discharge pipe 21 is communicated with the bottom of the crystallization tank 1, and one end of the discharge pipe 21 is communicated with the top of the separation tank 2.

[0031] A cooling pipe 11 is arranged on the outer side of the crystallization tank 1, the cooling pipe 11 is fixedly installed on the outer wall of the crystallization tank 1 and close to the bottom position, the liquid inlet 12 and the liquid outlet 13 of the cooling pipe 11 are respectively located at the two ends of the cooling pipe 11, the liquid inlet 12 is located below the liquid outlet 13, and the cooling pipe 11 is connected with an external cooling water source.

[0032] When the crystallization process reaches a certain extent, the heat source of the heating coil 10 is turned off, and the cooling water source of the cooling pipe 11 is turned on to cool the material in the crystallization tank 1, so that more monosodium glutamate crystals are precipitated. The liquid inlet end 12 and the liquid outlet end 13 of the cooling pipe 11 are located at both ends of the cooling pipe 11, and the liquid inlet end 12 is located below the liquid outlet end 13. The spiral structure of the cooling pipe 11 is arranged so that the cooling water flows from bottom to top. The spiral design of the cooling pipe 11 can make the material from the bottom to the top of the crystallization tank 1 be relatively uniformly cooled, and the heat can be uniformly dissipated from the material in the crystallization tank 1, so that the temperature in the entire crystallization tank 1 decreases uniformly, which helps to form uniform monosodium glutamate crystals and avoids the crystals being easily adhered to each other during subsequent transportation and screening, thereby improving the quality and purity of the product.

[0033] Further, the inside of the crystallization tank 1 is provided with a transmission shaft 6, and the surface of the crystallization tank 1 is provided with a servo motor 4. One end of the transmission shaft 6 penetrates the top of the crystallization tank 1 and is fixedly connected with the output shaft of the servo motor 4 in coaxial line. The surface of the transmission shaft 6 is fixedly provided with stirring blades 7.

[0034] The servo motor 4 is turned on, which can drive the transmission shaft 6 installed at the output shaft end of the servo motor 4 to rotate, and then the stirring blades 7 installed on the outside of the transmission shaft 6 can rotate to fully mix the material in the crystallization tank 1.

[0035] Example Two

[0036] Based on the improvement of Example One:

[0037] Further, a partition 9 is arranged on the inner wall of the crystallization tank 1, and a heating coil 10 is arranged in the partition 9. The heating coil 10 is spirally arranged in the partition 9 of the inner wall of the crystallization tank 1, and the heating coil 10 is connected with an external heat source.

[0038] The heating coil 10 is connected with a heat medium to heat the material in the crystallization tank 1, so that the monosodium glutamate solution reaches a saturated state and starts to crystallize. This targeted heating method can effectively start the crystallization process, greatly shorten the time required to reach the crystallization condition compared with natural cooling or slow heating, thereby improving the efficiency of the entire crystallization process. The heating coil 10 is arranged around the inner wall of the crystallization tank 1, which can make the heat be relatively uniformly distributed in the crystallization tank 1. This can avoid local overheating or overcooling, and ensure that the monosodium glutamate solution in the entire tank can reach a saturated state at a suitable temperature and crystallize, which helps to form monosodium glutamate crystals with relatively uniform size and regular shape, and avoids uneven heating, which may cause some areas to crystallize too quickly and form larger crystal nuclei, while other areas crystallize too slowly, resulting in a large difference in crystal size and affecting product quality.

[0039] Further, the outlet end of the discharge pipe 21 is connected to the separation tank 2 in a tangential direction, and a valve 14 is installed on the discharge pipe 21.

[0040] When the mixture of monosodium glutamate crystals and mother liquor enters the separation tank 2 from the tangential direction through the discharge pipe 21, a rotating motion is generated in the separation tank 2, which causes the mixture to generate a centrifugal force. Under the action of the centrifugal force, the heavier monosodium glutamate crystals are thrown to the edge and bottom of the separation tank 2, and the lighter mother liquor is concentrated in the central area or near the top. This distribution helps to preliminarily separate the crystals and the mother liquor, reduces the burden of subsequent separation devices such as the filter screen 15, and improves the overall separation efficiency.

[0041] Further, the filter screen 15 is fixedly installed inside the separation tank 2 at an inclination, the lower end of the filter screen 15 is connected to a discharge pipe 16, the end of the discharge pipe 16 extending out of the separation tank 2 is provided with a discharge valve 18, and the bottom of the separation tank 2 is provided with a discharge port 17.

[0042] Opening the valve 14 on the discharge pipe 21 causes the crystals to enter the separation tank 2 through the discharge pipe 21. In the separation tank 2, the monosodium glutamate crystals are screened on the filter screen 15. The smaller particles pass through the filter screen 15 and fall to the inner bottom of the separation tank 2, and the larger particles are intercepted on the surface of the filter screen 15 and are discharged through the discharge pipe 16, and then are re-injected into the crystallization tank 1 and can be used as crystal seeds to drive the crystallization of the material in the tank.

[0043] Further, the surface of the stirring blade 7 is integrally formed with a helical blade 8 having a helical structure.

[0044] The helical blade 8 integrally formed with the surface of the stirring blade 7 having a helical structure can more quickly mix the newly added material with the existing material in the tank, so as to ensure that the solution concentration in the entire crystallization tank 1 is uniform, and the crystallization process can be synchronized at each position, thereby improving the crystallization efficiency.

[0045] Further, a push plate 20 is slidingly attached to the inner bottom surface of the separation tank 2, a multi-stage hydraulic rod 19 is fixedly installed on one side surface of the separation tank 2, and the piston end of the multi-stage hydraulic rod 19 penetrates through the separation tank 2 and extends into the separation tank 2, and is connected to one side of the push plate 20.

[0046] The relatively pure monosodium glutamate crystals falling to the inner bottom of the separation tank 2 are pushed out of the discharge port 17 by the push plate 20 driven by the multi-stage hydraulic rod 19, and are concentrated and collected for processing.

[0047] Further, support legs 3 are fixedly installed at the bottom of the separation tank 2, and the bottom of the support legs 3 is provided with shock-absorbing pads. The heating coil 10 is made of stainless steel.

[0048] The bottom of the separation tank 2 is provided with support legs 3, and the bottom of the support legs 3 is provided with shock-absorbing pads to reduce vibration during operation of the equipment.

[0049] The surface of the feed pipe 5 is threadedly connected with a matching sealing cover.

[0050] The sealing cover is opened when the material is added, and after the material is added, the sealing cover is tightened at the end of the feed pipe 5 to prevent impurities from entering.

[0051] Working principle: in use, first open the sealing cover threadedly connected to the surface of the feed pipe 5, then pour the raw material into the crystallization tank 1 through the feed pipe 5, start the servo motor 4, then the servo motor 4 can drive the transmission shaft 6 installed at the output shaft end to rotate, then the stirring blade 7 installed on the outside of the transmission shaft 6 can rotate, fully mix the material in the crystallization tank 1, and the spiral blade 8 integrally formed on the surface of the stirring blade 7 has a spiral structure, which can more quickly mix the newly added material with the existing material in the tank to ensure uniform solution concentration in the entire crystallization tank 1, so that the crystallization process can be synchronized at all positions, thereby improving the crystallization efficiency;

[0052] At the same time, the heating coil 10 is connected to a heating medium to heat the material in the crystallization tank 1, so that the monosodium glutamate solution reaches a saturated state and begins to crystallize. This targeted heating method can effectively start the crystallization process, compared with natural cooling or slow heating, greatly shortening the time required to reach the crystallization condition, thereby improving the efficiency of the entire crystallization process. The heating coil 10 is arranged around the inner wall of the crystallization tank 1, which can relatively evenly distribute the heat in the crystallization tank 1, so as to avoid local overheating or undercooling, and ensure that the monosodium glutamate solution reaches a saturated state and crystallizes at a suitable temperature throughout the tank body. This helps to generate relatively uniform and regular-shaped monosodium glutamate crystals, avoids uneven heating, which may cause some areas to crystallize too quickly, forming larger crystal nuclei, while other areas crystallize too slowly, resulting in a large difference in crystal size and affecting product quality.

[0053] When the crystallization process reaches a certain extent, the heat source of the heating coil 10 is turned off, and the cooling water source of the cooling pipe 11 is turned on to cool the material in the crystallization tank 1, so that more monosodium glutamate crystals are precipitated. The liquid inlet end 12 and the liquid outlet end 13 of the cooling pipe 11 are located at both ends of the cooling pipe 11, and the liquid inlet end 12 is located below the liquid outlet end 13. The spiral structure of the cooling pipe 11 allows the cooling water to flow from bottom to top. The spiral design of the cooling pipe 11 can uniformly cool the material from the bottom to the top of the crystallization tank 1, and the heat can be evenly dissipated from the material in the crystallization tank 1, so that the temperature in the entire crystallization tank 1 decreases uniformly, which helps to form uniform monosodium glutamate crystals and avoid the mutual adhesion of the crystals during subsequent transportation and screening, thereby improving the quality and purity of the product.

[0054] After the crystallization is completed, the valve 14 on the discharge pipe 21 is opened, and the crystals are pushed into the separation tank 2 through the discharge pipe 21. In the separation tank 2, the monosodium glutamate crystals are screened on the filter screen 15. The smaller particles pass through the filter screen 15 and fall to the inner bottom of the separation tank 2, and the relatively pure monosodium glutamate crystals falling to the inner bottom of the separation tank 2 are pushed out of the discharge port 17 by the push plate 20 driven by the multi-stage hydraulic rod 19, and are collected and processed. The larger particles are intercepted on the surface of the filter screen 15 and are discharged through the discharge pipe 16, and are again put into the crystallization tank 1 and can be used as crystal seeds to drive the crystallization of the material in the tank.

[0055] When the mixture containing monosodium glutamate crystals and mother liquor enters the separation tank 2 from the tangent direction through the discharge pipe 21, a rotating motion is generated in the separation tank 2. This rotating motion causes the mixture to generate a centrifugal force. Under the action of the centrifugal force, the heavier monosodium glutamate crystals are thrown to the edge and bottom of the separation tank 2, and the lighter mother liquor is concentrated in the central area or near the top. This distribution helps to preliminarily separate the crystals and the mother liquor, reduces the burden of the subsequent separation devices such as the filter screen 15, and improves the overall separation efficiency.

[0056] It should be noted that the discharge valve 18 is used to control the opening and closing of the discharge pipe 16.

[0057] It should be noted that the bottom of the separation tank 2 is provided with support legs 3, and the bottom of the support legs 3 is provided with shock-absorbing pads to reduce vibration during equipment operation.
