Description

Technical Field

[0001] The present application relates to the technical field of reaction kettles, and in particular to a continuous reaction kettle for producing fully water-soluble nitro calcium silicate magnesium tablets. Background Art

[0002] Fully water-soluble nitro calcium silicate magnesium tablets are a kind of highly efficient water-soluble fertilizers, which have the characteristics of rapid dissolution, balanced nutrition and environmental protection. When producing fully water-soluble nitro calcium silicate magnesium tablets, it is necessary to mix powder materials and liquid materials in a reaction kettle. In order to meet the requirement of continuous feeding in the next process, a continuous reaction kettle is usually used to continuously stir and mix the powder materials and liquid materials for producing fully water-soluble nitro calcium silicate magnesium tablets.

[0003] Chinese Patent with publication number CN214183087U discloses a continuous reaction kettle and a continuous reaction system, which can realize continuous mixing and stirring of liquid-liquid or liquid-solid. An overflow channel is formed in the kettle body by arranging baffles, so that the liquid-liquid or liquid-solid mixed liquid can overflow and discharge from the kettle body after being stirred by the stirring structure. Due to the existence of the overflow channel, the mixed liquid can be discharged while being stirred and will not be discharged immediately like the discharge at the bottom end of the kettle body, so that the continuous mixing and stirring of liquid-liquid or liquid-solid can be carried out.

[0004] In the above solution, the stirring structure realizes stirring by driving the stirring blades to rotate with a stirring shaft. Although the overflow channel slows down the discharge time of the mixed liquid and provides sufficient stirring time for the stirring structure, however, since the stirring blades mainly stir in the horizontal plane, it is difficult for the stirring blades to effectively stir the mixed liquid after the mixed liquid flows through the stirring blades, resulting in poor overall mixing uniformity of the mixed liquid, and thus it is difficult to meet the uniformity requirement of continuous mixing of powder materials and liquid materials.

[0019] The following further elaborates on this application in conjunction with the attached Figure 1-8 drawings for a more detailed description.

[0020] This application example discloses a continuous reaction kettle for producing fully water-soluble nitro calcium magnesium silicate tablets. Referring to Figure 1 and Figure 2 , a continuous reaction kettle for producing fully water-soluble nitro calcium magnesium silicate tablets includes a kettle body 1, an overflow cylinder 2, a baffle plate 3, a first stirring assembly 4, a second stirring assembly 5, and a mixing assembly 6.

[0021] Referring to Figure 2, an overflow pipe 11 is connected to the top side wall of the kettle body 1, and the overflow pipe 11 is used for overflowing and discharging the mixed liquid. The overflow cylinder 2 is located inside the kettle body 1 and is fixedly connected to the top end of the kettle body 1. There is a gap between the bottom end of the overflow cylinder 2 and the bottom end of the kettle body 1, so that the mixed liquid inside the overflow cylinder 2 can flow into the space between the outer wall of the overflow cylinder 2 and the inner wall of the kettle body 1. The baffle plate 3 is slidably arranged in the overflow cylinder 2 along the axis direction of the overflow cylinder 2, and a plurality of baffle plates 3 are arranged along the sliding direction. The side edge of the baffle plate 3 is fitted with the inner wall of the overflow cylinder 2. The baffle plate 3 can extend the time for the mixed liquid to flow to the bottom end of the overflow cylinder 2, so as to extend the time for the mixed liquid to be stirred.

[0022] Among them, referring to Figure 3 , two sliding blocks 32 are symmetrically and fixedly connected to the side edge of the baffle plate 3. The sliding blocks 32 are slidably arranged in the sliding grooves 22 opened on the inner wall of the overflow cylinder 2. The sliding blocks 32 and the sliding grooves 22 together form the sliding connection structure between the baffle plate 3 and the overflow cylinder 2.

[0023] Specifically, referring to Figure 2 and Figure 4 , the first stirring assembly 4 includes a driving member 41, a stirring shaft 42, stirring plates 43 and a first transmission part 44.

[0024] Referring to Figure 2 , the driving member 41 is installed on the top end outside the kettle body 1. The stirring shaft 42 is rotatably connected in the kettle body 1 and is connected to the driving member 41. The stirring shaft 42 passes through all the baffle plates 3, and the stirring shaft 42 is reciprocally threadedly connected to the baffle plates 3. When the stirring shaft 42 drives the baffle plates 3 to slide, two adjacent baffle plates 3 are in a state of moving away from or approaching each other.

[0025] The driving member 41 is a power component capable of outputting a rotational force, such as a motor, a hydraulic motor or a rotary cylinder. Taking the motor as an example for detailed description, the motor is fixedly connected to the kettle body 1, the output shaft of the motor rotates and penetrates into the kettle body 1, and the output shaft of the motor is fixedly connected to the stirring shaft 42. The motor can drive the stirring shaft 42 to rotate.

[0026] Referring to Figure 4 , multiple groups of stirring plates 43 are provided. The multiple groups of stirring plates 43 are respectively located between two adjacent baffle plates 3. Each group of stirring plates 43 is provided with a plurality of stirring plates 43 around the stirring shaft 42. All the stirring plates 43 in each group are commonly connected with a connecting ring 431. The connecting ring 431 is nested on the stirring shaft 42 and is rotatably connected to the stirring shaft 42. The outer side wall of the connecting ring 431 is rotatably connected to the end of the stirring plate 43. The stirring shaft 42 supports the stirring plate 43 through the connecting ring 431.

[0027] There are multiple first transmission parts 44, which correspond to the stirring plates 43 one by one. The first transmission parts 44 are in transmission connection with the stirring plates 43 and the two baffle plates 3 close to the stirring plates 43. The first transmission parts 44 are used to drive the stirring plates 43 to turn the mixed liquid by means of the driving force formed by the sliding of the two baffle plates 3.

[0028] Referring to Figure 2 、 Figure 4 and Figure 5 , the second stirring assembly 5 includes a driving rod 51, a first stirring impeller 52 and a second transmission part 53.

[0029] Referring to Figure 2 and Figure 4 , multiple driving rods 51 are arranged around the stirring shaft 42. The driving rods 51 are fixedly connected to the bottom end of the kettle body 1 and slidably penetrate through all the baffle plates 3. Multiple groups of first stirring impellers 52 are provided. The multiple groups of first stirring impellers 52 are correspondingly arranged on the top surfaces of the multiple baffle plates 3. Each group of first stirring impellers 52 has multiple ones, which correspond to the driving rods 51 one by one. The first stirring impellers 52 are slidably sleeved on the driving rods 51, and the first stirring impellers 52 are rotatably connected to the baffle plates 3.

[0030] Referring to Figure 5 , multiple second transmission parts 53 are provided, which correspond to the first stirring impellers 52 one by one. The second transmission parts 53 are in transmission connection with the first stirring impellers 52 and the driving rods 51. The second transmission parts 53 are used to drive the first stirring impellers 52 to rotate by means of the driving force formed by the relative sliding of the first stirring impellers 52 with respect to the driving rods 51, so that the first stirring impellers 52 can stir the mixed liquid.

[0031] Wherein, the first stirring impeller 52 is fixedly connected with a rotating ring 521. The rotating ring 521 is rotatably connected in a rotating groove 33 opened on the baffle plate 3. The rotating ring 521 and the rotating groove 33 form the rotating connection structure between the first stirring impeller 52 and the baffle plate 3.

[0032] Referring to Figure 4 , multiple through-flow holes 31 are opened at the parts of the baffle plate 3 corresponding to each first stirring impeller 52. The through-flow holes 31 are used to allow the mixed liquid to flow through the baffle plate 3 to realize the continuous flow of the mixed liquid.

[0033] Referring to Figure 2 , the mixing assembly 6 includes a first telescopic rod 61.

[0034] There are multiple sets of the first telescopic rods 61, which are respectively arranged between two adjacent flow blocking plates 3. Each set of the first telescopic rods 61 has multiple rods arranged around the stirring shaft 42. Each set of the multiple first telescopic rods 61 corresponds to the driving rod 51 one by one. The first telescopic rod 61 has two movable ends that can independently expand and contract. The two movable ends of the first telescopic rod 61 are respectively fixedly connected to the two flow blocking plates 3. The rod body of the first telescopic rod 61 is fixedly connected to the inner wall of the overflow cylinder 2. Spaces for storing the mixed liquid are left in the two rod chambers of the first telescopic rod 61.

[0035] Referring to Figure 3 , a plurality of mixing pipes 62 are connected to the two rod chambers of all the first telescopic rods 61. The mixing pipes 62 can allow the mixed liquid to flow into or out of the rod chambers of the first telescopic rods 61. When the movable end of the first telescopic rod 61 extends, it can squeeze the mixed liquid in its own rod chamber and spray it out from the mixing pipe 62.

[0036] During use, the powder material and the liquid material are added into the kettle body 1. The powder material and the liquid material are stirred and mixed inside the overflow cylinder 2. The mixed liquid formed by the mixing of the powder material and the liquid material flows through the flow blocking plate 3 via the flow holes 31. Compared with the direct flow of the mixed liquid inside the overflow cylinder 2, the flow blocking effect of the multiple flow blocking plates 3 extends the time for the mixed liquid to flow to the bottom end of the overflow cylinder 2, thereby extending the time for the mixed liquid to be stirred. At the same time, the mixed liquid can be in a continuous flowing state inside the kettle body 1, which is conducive to ensuring the continuity of the production of fully water-soluble nitro calcium magnesium silicate tablets.

[0037] The driving member 41 drives the stirring shaft 42 to rotate. The stirring shaft 42 drives the flow blocking plate 3 to slide reciprocally through the reciprocating thread, so that two adjacent flow blocking plates 3 alternately move away from and close to each other; during the process of two adjacent flow blocking plates 3 moving away from or close to each other, the first transmission part 44 drives the stirring plate 43 to turn and stir by means of the driving force formed by the sliding of the two flow blocking plates 3, so that the stirring plate 43 can turn over the mixed liquid; during the sliding process of the flow blocking plate 3, the flow blocking plate 3 drives the first stirring impeller 52 to slide relative to the driving rod 51. The second transmission part 53 drives the first stirring impeller 52 to rotate by means of the driving force formed by the relative sliding of the first stirring impeller 52 relative to the driving rod 51, so that the first stirring impeller 52 can stir the mixed liquid. And because the flow holes 31 are opened at the parts of the flow blocking plate 3 corresponding to the first stirring impeller 52, the mixed liquid will pass through the stirring area of the first stirring impeller 52 when flowing, so that the mixed liquid can be fully stirred by the first stirring impeller 52.

[0038] During the process of two adjacent flow restrictors 3 moving away from or approaching each other, the first telescopic rod 61 can make both of its two movable ends alternately extend and contract by means of the driving force formed by the sliding of the two flow restrictors 3; when the movable end of the first telescopic rod 61 contracts, that is, when the two flow restrictors 3 approach each other, the mixed liquid between the two flow restrictors 3 will be extruded from the flow holes 31 out of the space between the two flow restrictors 3, and the mixed liquid between the two flow restrictors 3 will be squeezed into the rod chamber of the first telescopic rod 61 from the mixing pipe 62; when the movable end of the first telescopic rod 61 extends, that is, when the two flow restrictors 3 move away from each other, the mixed liquid on the side where the two flow restrictors 3 move away from each other will be squeezed into the space between the two flow restrictors 3 from the flow holes 31, and the mixed liquid in the rod chamber of the first telescopic rod 61 will be squeezed out into the space between the two flow restrictors 3 from the mixing pipe 62. Since the first telescopic rod 61 is arranged corresponding to the driving rod 51, the mixed liquid flow squeezed out from the mixing pipe 62 and the mixed liquid flow squeezed into from the flow holes 31 can collide with each other, and the two mixed liquid flows can be fully mixed during the collision process.

[0039] Through the agitation of the mixed liquid by the stirring plate 43, the overall stirring of the mixed liquid by the first stirring impeller 52, and the collision mixing of the two mixed liquid flows, the mixed liquid can be jointly agitated in three forms within the kettle body 1. Under the action of the joint agitation in the three forms, when the mixed liquid flows through multiple flow restrictors 3, it can not only always be fully and effectively agitated, but also the stirring effect received by the mixed liquid is always better than that of the stirring blades in the prior art, thereby improving the overall mixing uniformity of the powder material and the liquid material and meeting the uniformity requirements for the continuous mixing of the powder material and the liquid material.

[0040] Specifically, referring to Figure 6 , the first transmission part 44 includes a first stirring gear 441 and a first stirring rack 442.

[0041] Referring to Figure 4 and Figure 6 , the first stirring gear 441 is fixedly connected to the end of the stirring plate 43 close to the connecting ring 431. There are two first stirring racks 442 arranged centrosymmetrically. The two first stirring racks 442 are respectively located on both sides of the first stirring gear 441. The two first stirring racks 442 are both meshed with the first stirring gear 441, and the two first stirring racks 442 are respectively fixedly connected to the two flow restrictors 3 close to the stirring plate 43.

[0042] When the flow restrictor 3 slides, the flow restrictor 3 can drive the first stirring rack 442 to move. The first stirring rack 442 can drive the first stirring gear 441 to rotate. The first stirring gear 441 can drive the stirring plate 43 to rotate, so that the stirring plate 43 can agitate the mixed liquid.

[0043] Specifically, referring to Figure 5The second transmission part 53 includes two stirring sliders 531, and the two stirring sliders 531 are symmetrically fixed to the first stirring impeller 52. The stirring sliders 531 are slidably arranged in the spiral driving grooves 511 provided on the driving rod 51. When the baffle plate 3 drives the first stirring impeller 52 to slide relative to the driving rod 51, the stirring sliders 531 can slide relative to the driving rod 51. Under the spiral guiding action of the spiral driving grooves 511, the stirring sliders 531 can drive the first stirring impeller 52 to rotate around the driving rod 51, so that the first stirring impeller 52 can stir the mixed liquid.

[0044] Specifically, refer to Figure 3 The mixing assembly 6 also includes a flushing pipe 63, of which there are multiple flushing pipes 63, which correspond one to one with the first telescopic rod 61. One end of the flushing pipe 63 is connected to the middle part of the first telescopic rod 61, and the other end is fixedly penetrated on the overflow tube 2. The rodless cavity of the first telescopic rod 61 has space for storing the mixed liquid.

[0045] When the movable end of the first telescopic rod 61 is extended, the mixed liquid between the outer wall of the overflow tube 2 and the inner wall of the kettle body 1 can flow from the flushing tube 63 into the rodless cavity of the first telescopic rod 61. When the movable end of the first telescopic rod 61 is contracted, the mixed liquid in the rodless cavity of the first telescopic rod 61 can be squeezed out from the flushing tube 63 to between the outer wall of the overflow tube 2 and the inner wall of the kettle body 1, and the mixed liquid flow can impact on the inner wall of the kettle body 1. The stable flow of the mixed liquid between the outer wall of the overflow tube 2 and the inner wall of the kettle body 1 is broken by the impact of the liquid flow, so that the mixed liquid can be disturbed by the liquid flow and the mixing uniformity is further improved.

[0046] Reference Figure 7 In order to further improve the mixing uniformity of the mixed liquid, the continuous reactor for producing fully water-soluble nitro-silicon calcium magnesium tablets in the present application also includes a third stirring component 7, and the third stirring component 7 includes a second stirring impeller 71 and a third transmission part 72.

[0047] Reference Figure 2 and Figure 7 , multiple groups of second stirring impellers 71 are arranged around the overflow tube 2, and are all located in the overflow channel 21 formed between the outer wall of the overflow tube 2 and the inner wall of the kettle body 1. Multiple second stirring impellers 71 are arranged in each group along the sliding direction of the baffle plate 3, and the second stirring impellers 71 are rotatably connected to the overflow tube 2. Multiple third transmission parts 72 are provided, and correspond to multiple groups of second stirring impellers 71 one by one. The third transmission parts 72 are transmission-connected to a corresponding group of second stirring impellers 71 and the baffle plate 3 closest to the bottom end of the kettle body 1. The third transmission parts 72 are used to drive the corresponding group of second stirring impellers 71 to rotate by means of the driving force formed by the sliding of the baffle plate 3.

[0048] When the baffle plate 3 slides, the third transmission part 72 can drive the corresponding set of second stirring impellers 71 to rotate by means of the driving force formed by the sliding of the baffle plate 3 closest to the bottom end of the kettle body 1, so that the second stirring impellers 71 can stir the mixed liquid in the overflow channel 21, so that the mixed liquid can also be stirred in the overflow channel 21, thereby further improving the mixing uniformity of the mixed liquid.

[0049] Specifically, referring to Figure 7 , the third transmission part 72 includes a second stirring gear 721 and a second stirring rack 722.

[0050] Referring to Figure 2 and Figure 7 , a plurality of second stirring gears 721 are provided, and are in one-to-one correspondence with a plurality of second stirring impellers 71 in the corresponding set. The second stirring gears 721 are fixedly connected to the second stirring impellers 71. The second stirring rack 722 is slidably arranged on the overflow cylinder 2 and meshes with all the second stirring gears 721. A connecting rod 723 is fixedly connected to the second stirring rack 722, and one end of the connecting rod 723 away from the second stirring rack 722 is fixedly connected to the baffle plate 3 closest to the bottom end of the kettle body 1.

[0051] The baffle plate 3 closest to the bottom end of the kettle body 1 can drive the connecting rod 723 to move, the connecting rod 723 can drive the second stirring rack 722 to slide, the second stirring rack 722 can drive the second stirring gear 721 to rotate, and the second stirring gear 721 can drive the second stirring impeller 71 to rotate, so that the second stirring impeller 71 can stir the mixed liquid in the overflow channel 21.

[0052] Furthermore, referring to Figure 7 , for any two adjacent third transmission parts 72, the position of the second stirring rack 722 of one third transmission part 72 relative to the second stirring gear 721 is the same as the position of the second stirring rack 722 of the other third transmission part 72 relative to the second stirring gear 721.

[0053] Since the positions of the second stirring racks 722 relative to the second stirring gears 721 in two adjacent third transmission parts 72 are the same, the rotation directions of two adjacent sets of second stirring impellers 71 are the same, so that the liquid flow directions formed by the two adjacent sets of second stirring impellers 71 stirring the mixed liquid can be the same, so that the liquid flow directions formed on the side where two adjacent sets of second stirring impellers 71 are close to each other can be exactly opposite, increasing the non-uniformity of the mixed liquid flow and enhancing the stirring effect of the mixed liquid in the overflow channel 21.

[0054] Referring to Figure 2 and Figure 8, in order to improve the mixing uniformity of the mixed liquid at the bottom end of the overflow cylinder 2, the mixing assembly 6 further includes a plurality of second telescopic rods 64, which correspond to the connecting rods 723 one by one. Each second telescopic rod 64 has a movable end. The rod body of the second telescopic rod 64 is connected to the bottom end of the kettle body 1, and the movable end of the second telescopic rod 64 is fixedly connected to the connecting rod 723. The second telescopic rod 64 is located between the bottom end of the overflow cylinder 2 and the bottom end of the kettle body 1. A plurality of flushing holes 641 are formed in the rodless cavity of the second telescopic rod 64, and a space for storing the mixed liquid is left in the rodless cavity of the second telescopic rod 64.

[0055] When the connecting rod 723 moves following the baffle 3, the connecting rod 723 can alternately drive the second telescopic rod 64 to extend and contract. When the second telescopic rod 64 extends, the mixed liquid can flow into the rodless cavity of the second telescopic rod 64 from the flushing holes 641. When the second telescopic rod 64 contracts, the mixed liquid in the rodless cavity of the second telescopic rod 64 can be extruded from the flushing holes 641. The mixed liquid flow flowing out of the flushing holes 641 can form a liquid flow impact on the mixed liquid at the bottom end position of the overflow cylinder 2, improving the mixing uniformity of the mixed liquid at the bottom end position of the overflow cylinder 2.

[0056] Further, referring to Figure 2 and Figure 8 , the rod body of the second telescopic rod 64 is respectively rotatably connected to the kettle body 1 and the movable end of the second telescopic rod 64. Two rotating sliders 642 are symmetrically and fixedly connected to the movable end of the second telescopic rod 64. The rotating sliders 642 are slidably arranged in spiral rotating grooves 643 formed in the inner wall of the rod body of the second telescopic rod 64.

[0057] When the movable end of the second telescopic rod 64 moves following the connecting rod 723, the movable end of the second telescopic rod 64 can move relative to the rod body of the second telescopic rod 64, so that the rotating sliders 642 on the movable end of the second telescopic rod 64 can slide relative to the rod body of the second telescopic rod 64. Since the rotating sliders 642 are slidably arranged in the spiral rotating grooves 643, when the rotating sliders 642 move following the movable end of the second telescopic rod 64, they can drive the rod body of the second telescopic rod 64 to rotate by pushing the groove wall of the spiral rotating groove 643. The flushing holes 641 rotate following the rod body of the second telescopic rod 64, so that the mixed liquid flow flowing out of the flushing holes 641 can stir the mixed liquid.

[0058] Referring to Figure 2 , in order to prevent the powder from floating around during feeding, a mixing assembly 8 is further included in the continuous reaction kettle for producing fully water-soluble nitro calcium magnesium tablets of the present application. The mixing assembly 8 includes a receiving tray 81 and a mixing scraping bar 82.

[0059] Referring to Figure 1 and Figure 2, the receiving tray 81 is conical and fixedly connected to the top inside the kettle body 1. The receiving tray 81 is located inside the overflow cylinder 2. A feeding hole 811 is provided at the center of the receiving tray 81. The top of the kettle body 1 is connected to a powder pipe 12 and a liquid pipe 13. The powder pipe 12 is used to introduce powder, and the liquid pipe 13 is used to introduce liquid. Both the powder pipe 12 and the liquid pipe 13 feed materials onto the receiving tray 81. A plurality of mixing scraping bars 82 are arranged around the stirring shaft 42. One end of the mixing scraping bar 82 is fixedly connected to the stirring shaft 42. One side of the mixing scraping bar 82 is attached to one side of the receiving tray 81 close to the top of the kettle body 1.

[0060] The powder and liquid can be added onto the receiving tray 81 through the powder pipe 12 and the liquid pipe 13. The mixing scraping bar 82 can rotate with the stirring shaft 42. During the rotation, the mixing scraping bar 82 can scrape the powder and liquid to come into contact inside the receiving tray 81, so that the powder and liquid are mixed inside the receiving tray 81, so that when the powder enters the overflow cylinder 2 from the feeding hole 811, it is not easy to disperse everywhere, so as to avoid that some powder is difficult to mix into the liquid.

[0061] The implementation principle of a continuous reaction kettle for producing fully water-soluble nitro calcium magnesium tablets in an embodiment of the present application is as follows: during use, powder and liquid are added into the kettle body 1. The driving member 41 drives the stirring shaft 42 to rotate, and the stirring shaft 42 drives the baffle 3 to slide reciprocally, so that two adjacent baffles 3 approach or move away from each other. When the baffle 3 slides, it drives the stirring plate 43, the first stirring impeller 52, the first telescopic rod 61 and the second stirring impeller 71 to act. The stirring plate 43 turns the mixed liquid, the first stirring impeller 52 stirs the mixed liquid inside the overflow cylinder 2, the first telescopic rod 61 impacts the mixed liquid, and the second stirring impeller 71 stirs the mixed liquid inside the overflow channel 21. Thus, through the combined agitation of stirring, turning and impacting mixing, the overall mixing uniformity of the powder and liquid is improved, meeting the uniformity requirements for the continuous mixing of the powder and liquid.

[0062] The above are all preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
