Description

Technical Field

[0001] The invention belongs to the technical field of seasoning salt production, and in particular relates to a production device for zinc-magnesium seasoning salt and a preparation method thereof. Background Art

[0002] Edible salt, categorized as well salt, sea salt, pond salt, and rock salt, contains a variety of nutrients, including iron, calcium, zinc, potassium, sodium, and iodine. Table salt is a type of salt, specifically sodium chloride. Salt is also an essential element for the human body, regulating its function.

[0003] With the continuous development and progress of society, people's living standards have also been improved, and higher requirements have been put forward for the consumption of table salt, such as table salt containing special nutrients or seasoning salt containing multiple nutrients, especially for zinc and magnesium.

Severe cases can cause children to have mental retardation, developmental delay, short stature, etc. Magnesium deficiency may cause nerve and muscle damage, and may also cause arrhythmia. Severe cases can also lead to cardiovascular disease. Therefore, the intake of various nutrients is necessary and indispensable.

[0004] At present, in the production and processing process of zinc-magnesium seasoning salt, it is generally to extract high-purity zinc and magnesium elements from zinc-magnesium-rich ores, and then acid-leach the ores to obtain a solution containing the corresponding elements, and then adopt electrolysis or chemical methods to obtain edible salt containing zinc and magnesium elements. Finally, the edible salts containing zinc and magnesium elements are mixed in proportion to prepare seasoning salt containing zinc and magnesium elements to meet different market usage needs; in the prior art, whether it is the preparation process of magnesium salt or zinc salt, the reaction is first carried out in a reaction vessel to prepare the required solution, and then the obtained solution is placed in a crystallization tank for corresponding crystallization treatment to obtain crystals containing magnesium and zinc elements, and then secondary mixing is carried out in subsequent production to prepare the finished product.

A guide plate 5 is tilted on the inner side of the support frame 1 below the hopper 23 to facilitate the introduction of materials in the hopper 23 into the reaction bin 6. Furthermore, in order to effectively prepare the work, the stirring mechanism includes a reaction bin 6. A lifting and movable sealing bin door 61 is provided above the reaction bin 6. The cooperation between the sealing bin door 61 and the upper end of the reaction bin 6 makes the reaction bin 6 sealed, ensuring the effective progress of the reaction.

Of course, the lower end of the partition 63 can also be set to be the same, that is, the two areas in the reaction bin 6 are connected to the principle of communicating vessels, which provides convenient conditions for realizing the overall reaction of the materials and meets the needs of production and processing. Furthermore, a first refrigeration plate 64 is provided in the partition 63, which is used to cool the reaction bin 6 to meet the needs of crystallization. A heating plate 65 is provided on the outside of the reaction bin 6, which is used for The materials are heated during the reaction to ensure that they have good reaction conditions. A stirring assembly is provided below the reaction bin 6. On the one hand, the materials in the reaction bin 6 can be stirred to react, thereby ensuring the progress of production and processing work. On the other hand, it can also realize the introduction of part of the reactants to ensure the effective progress of the reaction. The material transfer mechanism 13 receives and exports the crystallized solution to ensure the continuity of production and processing work. The lower end of the reaction bin 6 is provided with a filtering mechanism 8 for filtering the solution. A filtrate assembly 12 is provided below the filtering mechanism 8. The filtering mechanism 8 and the filtrate assembly 12 are used in conjunction with each other to complete the export of the crystallized solution, thereby avoiding the possibility of waste of production materials and saving production costs.

[0040] In the above process: the raw materials can be crushed by the provided crushing mechanism, providing convenient conditions for their subsequent reaction; the material guide plate 5 can be freely adjusted according to different usage requirements to ensure the accuracy of the material falling position and improve the work progress; the funnel mechanism can be used to collect the quantitative and crushed raw materials and complete the centralized export, which to a certain extent ensures the smooth progress of the production and processing work; the reaction chamber 6 is provided to provide a good reaction space for the preparation of salt, and can also realize crystallization precipitation, and with the cooperation of the filtering mechanism 8 and the filtrate component 12, the export of the crystallized solution is completed, avoiding the possibility of waste of production materials and saving production costs; the device has a reasonable design, simple structure, easy processing and can integrate reaction and crystallization filtration functions, ensuring the functionality of the device and equipment, effectively improving the work progress, reducing the possibility of waste of production materials, saving production costs, and effectively meeting the production and processing needs.

[0041] In order to effectively complete the export of raw materials, the rotating assembly 3 includes a rotating seat 31 installed on the support frame 1, and a supporting frame 32 for docking the hopper 23 is provided between the two rotating seats 31, wherein a rotating shaft is provided in the rotating seat 31 and is respectively connected to the two ends of the supporting member so that the supporting frame 32 can rotate. Of course, the rotating power of the supporting frame 32 can be provided by a driving motor, that is, a driving motor is provided on the outside of the support frame 1, and its output end is connected to the rotating shaft to provide conditions for unloading the raw materials. The locking mechanism 4 includes an ear seat 33 connected to the lower end of the supporting frame 32, and a locking drive cylinder 41 is provided in the ear seat 33; in order to stably place the receiving hopper 23 in the supporting frame 32 to prevent it from being out of place when rotating. Now it falls, the output end and tail end of the locking drive cylinder 41 are provided with a locking claw 42 of L-shaped design, and the inner side of the short side of the locking claw 42 is against the top of the receiving hopper 23. It is specifically described as follows: the outer side of the locking drive cylinder 41 is rotatably connected to the ear seat 33. On the one hand, it is used to ensure the stability of the locking drive cylinder 41, and on the other hand, it is to avoid motion interference. Further, the rear end of the locking drive cylinder 41 is hinged to the lower end of one locking claw 42, and its output end is hinged to the lower end of the other locking claw 42. In this way, the locking claws 42 are respectively placed on the upper corners of the receiving hopper 23, and the extension of the locking drive cylinder 41 is used to lock the equipment to ensure the stability of its position and prevent it from deflecting, thereby meeting the use requirements.

[0042] In order to further improve the functionality of the device, a slide rail 51 is inclinedly arranged on the inner side of the support frame 1 corresponding to the guide plate 5, and a slider 52 is arranged on the slide rail 51, and is connected to the outer side of the guide plate 5. Considering the process of feeding the material into the reaction bin 6, it is necessary to lift the sealed bin door 61 to allow the material to fall into the reaction bin 6. That is to say, during the material feeding process, the guide plate 5 is controlled to move toward the side of the feed port close to the reaction bin 6 to facilitate the full fall of the material. When the reaction preparation is started, the guide plate 5 is controlled to move toward a position away from the reaction bin 6, providing a prerequisite for the descent of the sealed bin door 61, thereby improving the working process. It needs to be further explained that for the movement and operation process of the guide plate 5, a telescopic cylinder can be set on the support frame 1 below it for control, or one of the slide rails 51 can be set as a rodless cylinder 1310 to ensure the effective input of driving power.

[0043] In order to achieve stirring of the material in the reaction bin 6 and ensure the effective progress of the reaction, the stirring assembly includes a hollow stirring shaft 7 spanning the reaction bin 6, and a through hole 71 is opened on the outer circumference of the hollow stirring shaft 7. It should be further explained that: the outside of the reaction bin 6 is also provided with a motor for driving the hollow stirring shaft 7 to rotate to ensure driving power. At the same time, the outside of the hollow stirring shaft 7 can also be provided with a stirring blade (not shown in the figure). In addition, the purpose of the stirring shaft with a hollow design is that the other end can be connected to a gas delivery pipeline or a liquid delivery pipeline, and with the help of the through hole 71, the material input is realized to ensure the effective progress of the reaction. The device is reasonably designed and has strong functionality. It should be further explained that gas delivery provides convenient conditions for the preparation of magnesium salt, that is, it is used to realize the introduction of hydrogen chloride gas, and the liquid delivery pipe can be used to introduce aqueous solution, hydrochloric acid solution or citric acid solution. Of course, when the reaction bin 6 is designed according to the principle of a communicating vessel, the two stirring assemblies can be used for different materials for material transportation, fully improving the functionality of the device and improving the work process.

[0044] In order to ensure the effective progress of the reaction in the reaction chamber 6 and provide convenient conditions for the placement of the sealed chamber door 61, a limit rod 611 is provided on the support frame 1 located between the two material guide plates 5, which limits the lifting direction of the sealed chamber door 61. That is to say, the corners of the sealed chamber door 61 are mounted on the limit rod 611, and the driving power for the lifting and lowering movement of the sealed chamber door 61 can be provided by a telescopic cylinder, that is, four are set at the inner corners of the support frame 1, which are respectively connected to the upper corners of the sealed chamber door 61, providing a prerequisite for driving it to rise and fall freely, and to a certain extent ensuring the effective progress of the reaction process in the chamber, meeting the use requirements.

[0045] In order to effectively complete the filtration and export of the solution in the reaction chamber 6, the filtering mechanism 8 includes a mounting plate 81 connected to the lower end of the reaction chamber 6, a rotating rod 82 is provided in the mounting plate 81, and an upper through groove 811 and a lower through groove 812 are respectively provided in the mounting plates 81 on both sides of the rotating rod 82, and correspond to the discharge trough 62 set up in the reaction chamber 6 so that the solution can be exported. A plurality of guide grooves 821 with a blunt-angle design are evenly distributed in the rotating rod 82, and a drainage groove 813 is also provided in the mounting plate 81. A driving rotating rod 82 is provided on one side of the reaction chamber 6 to rotate and realize the upper through groove 811 and the drainage groove 813 and the drainage groove 813 respectively. The driving mechanism 9 is connected to the groove 813 and the lower groove 812. The driving mechanism 9 includes a mounting seat 91 connected to the support frame 1. One side of the mounting seat 91 is provided with a rotating driving cylinder 92 connected thereto and rotatable. One end of the rotating rod 82 is provided with a connecting block 93, and the other end thereof is connected to the rotating driving cylinder 92. One end of the connecting block 93 is fixedly connected to the rotating rod 82, and the other end is hinged to the rotating driving cylinder 92. In addition, the extension and contraction of the rotating driving cylinder 92 are used to adjust the position of the rotating rod 82. One is the upper groove 811, the guide groove 821 and the drainage groove. 813 is connected, and the other is that the drainage groove 813, the guide groove 821 and the lower through groove 812 are connected to realize the quantitative extraction of the solution and provide a prerequisite for the subsequent further crystallization treatment. Of course, in the above process, the rotating rod 82 is reciprocating, that is, it rotates only on the side close to the drainage groove 813 to avoid the possibility of solution overflow. The specific description is: when the solution needs to be extracted, the rotation drive cylinder 92 is controlled to operate, driving the rotating rod 82 to adjust to the first connection mode, and the solution is extracted through the upper through groove 811 and the guide groove 821. At the same time, the liquid guide mechanism 10 is operated, especially the liquid guide rod 1 is controlled. 05 moves outward so that the solution can be guided into the drainage trough 813. When it reaches the farthest moving distance, the rotation drive cylinder 92 is controlled to extend, driving the rotating rod 82 to rotate. On the one hand, it blocks the discharge trough 62, and on the other hand, it facilitates the transition to the second connection mode. When the second connection mode is in the connection state, the liquid guiding mechanism 10 is controlled to operate, the solution is pushed out, and it flows through the guide groove 821 to the lower through groove 812, completing the guidance of the solution toward the filtrate component 12. The derivation of the quantitative solution can facilitate secondary crystallization, further play a role in saving production materials and saving production costs.

[0046] In order to effectively complete the extraction and discharge of the solution, the front and rear sides of the reaction chamber 6 are also provided with a liquid guide mechanism 10 for draining the temporarily stored solution in the drainage groove 813. The liquid guide mechanism 10 includes a rotating plate 101 connected to the upper corner of the reaction chamber 6, and a support rod 102 is provided at the lower end of the rotating plate 101. The two ends of the support rod 102 are provided with a connecting rod 103, wherein the two ends of the connecting rod 103 are respectively hinged with the support rod 102 and the connecting rod 103 to avoid motion interference. A liquid guide drive cylinder is also provided at the geometric center of the outer side of the reaction chamber 6 and at a position corresponding to one of the rotating plates 101. Of course, its mounting end and output end are respectively hinged to the outer side of the reaction chamber 6 and the rotating plate 101 to ensure the effective provision of driving power. A connecting plate 104 is provided between the two connecting rods 103. A plurality of liquid guide rods 105 are evenly distributed on the connecting plate 104 and are adapted to the drainage groove 813. Of course, a sealing ring is provided on the outer periphery of one end of the liquid guide rod 105. And it fits on the inner wall of the drainage groove 813 to avoid leakage. It is specifically described as follows: when it is necessary to extract the solution in the reaction chamber 6, the liquid guide driving cylinder is controlled to extend, and the rotating plate 101 rotates relative to the reaction chamber 6. Under the action of the support rod 102 and the connecting rod 103, the connecting plate 104 can be driven to move to a position away from the reaction chamber 6. At the same time, the liquid guide rod 105 is also pulled out. Then, after the filtering mechanism 8 adjusts to the next workstation, the liquid guide driving cylinder is controlled to contract to drive the liquid guide rod 105 to reset and drain the solution in the drainage groove 813, providing convenient conditions for subsequent production and processing work. In addition, it needs to be further explained that: limiting holes are also provided at both ends of the connecting plate 104, and a guide rod (not shown in the figure) is provided on the reaction chamber 6 corresponding to the limiting hole to limit the moving direction of the connecting plate 104. On the one hand, it prevents the possibility of overload during movement, and on the other hand, it prevents it from offsetting during movement to ensure usage requirements.

[0047] In order to effectively complete the installation of the filtrate assembly 12, a limiting plate 11 is provided at the lower end of the mounting plate 81, and a pulley 111 is provided on the inner side of the limiting plate 11, that is to say: the upper filter plate 121 in the filtrate assembly 12 has a protruding plate extending outward at the corner, which can be placed on the pulley 111 and moved under the drive of the pulley 111 until it can be moved to the geometric center to filter out the derived solution and ensure the working process; further speaking: the filtrate assembly 12 includes an upper filter plate 121, a liquid separator 122, a second refrigeration plate 123 and a lower filter plate 124, among which the second refrigeration plate 123 plays a cooling role, which can prevent the possibility of crystals not being precipitated during the derivation of the quantitative solution, and the upper filter plate 121 and the lower filter plate 124 are centrally symmetrical The purpose of the design is to filter out the solution in batches to ensure the working process. Correspondingly, the two liquid separation plates 122 are also arranged in a central symmetrical shape, isolating the solution from the second refrigeration plate 123 respectively, ensuring the effective subsequent cooling and providing a prerequisite for crystallization; in order to ensure the convenience of solution transportation and derivation process and to ensure the corresponding crystallization work, a plurality of first lower liquid troughs 1211 are evenly distributed in the upper filter plate 121, and a first connecting groove 1212 with an inclined design is provided on one side of a row of first lower liquid troughs 1211, and its ends respectively pass through the liquid separation plate 122 and the first refrigeration plate 64 and are derived from the lower filter plate 124, and a plurality of second lower liquid troughs 1241 are evenly distributed in the lower filter plate 124, and a first connecting groove 1212 with an inclined design is provided on one side of a row of first lower liquid troughs 1211. A second communicating groove 1242 of inclined design is provided on the side, and a central tube 125 is provided in the lower filter plate 124 corresponding to the second lower liquid groove 1241. The specific description is as follows: Taking into account that there are solution outlet areas on the left and right sides in the reaction chamber 6, for the first lower liquid groove 1211 provided on the upper filter plate 121, it receives the solution to circulate through the first communicating groove 1212. When flowing through the area of ​​the second refrigeration plate 123, the crystals that may be contained in the quantitative solution can be precipitated, and then guided downward by the end of the first communicating groove 1212. For the second lower liquid groove 1241 provided on the lower filter plate 124, its part corresponds to the first lower liquid groove 1211 on the other side of the upper filter plate 121. The solution passes through the upper filter plate 121, the separation plate 123, and the separation plate 123. The liquid plate 122 and the second refrigeration plate 123 are introduced into the second lower liquid tank 1241, and then flow under the action of the second connecting tank 1242.

[0051] Among them, the selected zinc ore and magnesium ore are ores with high content of corresponding elements to ensure the production and processing process and save production input costs. After the two ores are crushed separately, they are calcined or sintered according to their corresponding processing conditions to obtain raw materials containing zinc oxide and magnesium oxide, which provides convenient conditions for the subsequent preparation of zinc salt or magnesium salt;

[0052] The preparation of zinc salt and magnesium salt comprises the following steps:

[0053] S2: According to the processing step, the zinc oxide raw material and the magnesium oxide raw material are respectively put into the crushing mechanism for crushing. The crushed materials are discharged by the funnel mechanism and then fall into the reaction chamber 6 through the guide plate 5;

[0054] In the above process, the raw materials are crushed into powder respectively, which provides convenient conditions for the subsequent reaction. After a certain amount of raw materials are fully crushed, they can be concentrated and dropped into the receiving hopper 23, and then poured onto the guide plate 5 by the funnel mechanism, so that the raw materials can fall into the reaction chamber 6. Of course, in this process, the sealed chamber door 61 is located above the reaction chamber 6 to avoid being restricted in the export process of the raw materials and to improve the working process. At the same time, the movable and adjustable guide plate 5 can be adjusted to its position according to different usage requirements, which not only provides convenience for the introduction of materials, but also provides a prerequisite for the convenient placement of the sealed chamber door 61, greatly improving the functionality of the device and meeting the usage requirements.

[0055] S3: Zinc salt preparation process: water is injected into the reaction chamber 6 containing the zinc oxide raw material, and then a citric acid solution is introduced into the reaction chamber 6 through the stirring mechanism, while heating the reaction chamber 6, so that the zinc oxide and the citric acid react to produce zinc citrate; magnesium salt preparation process: water and a hydrochloric acid solution are injected into the reaction chamber 6 containing the magnesium oxide raw material to obtain a solution containing magnesium ions, and then hydrogen chloride gas is introduced into the reaction chamber 6 through the stirring mechanism, and the reaction conditions are adjusted so that the solution and the hydrogen chloride gas react to produce magnesium chloride;

[0056] In the above process, the introduction of the reaction solution or reaction gas during the reaction is carried out through the hollow shaft of the stirring mechanism, which not only realizes the convenient addition of reactants and ensures the sufficiency of the reaction process, but also ensures the effective progress of the production and processing, improves the work progress, and meets the production and processing needs.

[0057] S4: After the zinc salt and magnesium salt are prepared in S3, the solution is crystallized in the reaction chamber 6. After the crystallization process continues for a period of time, the filtration mechanism 8 is controlled to operate to separate the solution from the crystals, and secondary crystallization is performed during the solution extraction process;

[0058] In the above process, the filter mechanism 8 can separate and extract the crystallized solution from the reaction chamber 6, and the quantitatively extracted solution can be subjected to secondary crystallization under the action of the filtrate component 12, thereby reducing the possibility of waste of production materials and saving production costs.

[0059] The preparation of zinc-magnesium seasoning salt comprises the following steps:

[0060] S5: Weigh a certain amount of zinc citrate in S4 and mix it with the mother salt to obtain a zinc citrate mother liquor, and mix the mother liquor with edible salt and the magnesium salt in S3 for a second time to prepare a seasoning salt containing zinc and magnesium elements;

[0061] In the above process: the mother salt and edible salt selected are preferably refined salt or powdered washed salt, which are used to ensure the preparation of zinc-magnesium seasoning salt. The prepared zinc salt needs to be crushed into powder to carry out subsequent mixing work to ensure that it can be mixed and bonded with the mother salt, to ensure the uniformity of the zinc salt and the zinc adding effect. The purpose of the secondary mixing is to ensure the effective preparation of zinc-magnesium seasoning salt; in addition, it needs to be further explained that: the above mixing process can be carried out in the reaction chamber 6, so as to achieve the uniformity of the mixing with the help of the stirring mechanism, and then the quantitative extraction is carried out by the filtering mechanism 8, which is convenient for the subsequent corresponding packaging work.
