Description

Technical Field

[0001] The invention relates to the field of chemical reactors, and more specifically to a solid-liquid mixing chemical reactor. Background Art

[0002] With the continuous development of the chemical industry, more and more chemical reactions require the joint participation of solid and liquid materials, such as in the fields of pharmaceuticals, fine chemicals, and food. In the process of mixing solid and liquid materials, the reaction rate of the solid-liquid mixture plays a vital role. It directly determines the reaction effect of the materials. When the reaction rate is high, the solid and liquid materials can fully contact and react, so that the solid and liquid reaction effect is better, otherwise it will reduce the reaction effect of the solid and liquid. In the process of some solid and liquid reactions, the pH value of the solid-liquid mixture will affect the reaction rate of the solid-liquid mixture. The appropriate pH value will promote the reaction of the mixed material and improve its reaction effect. Otherwise, it will inhibit the reaction and reduce the reaction rate. Therefore, most of the existing chemical reactors are equipped with pH sensors to monitor the pH of the solid-liquid mixture inside the equipment in real time.

[0003] However, most of the existing pH sensors are fixed and can only monitor the pH value of a certain area of ​​the solid-liquid mixture inside the equipment. Since the overall pH value of the solid-liquid mixture is affected by factors such as the adequacy of the mixing of the solid-liquid mixture and the difference in material properties, the overall pH value of the solid-liquid mixture is prone to unevenness. Therefore, monitoring the pH value of the overall solid-liquid mixture by a fixed pH sensor is prone to inaccurate monitoring. Therefore, it is urgent to design a chemical reactor for solid-liquid mixing to solve the above problems. Summary of the invention

[0051] See also Figures 1 to 15 , a chemical reaction kettle for mixing solid and liquid, comprising a kettle body 1, on which a mixing motor 2 is fixedly mounted;

[0052] The driving end of the mixing motor 2 is fixedly mounted with a rotating cylinder 3, on which a feeding assembly 5 is arranged, the feeding assembly 5 comprises a connecting member 56 fixedly mounted on the rotating cylinder 3, on which a feeding cylinder 57 is fixedly mounted, on which a feeding component is mounted, in which an extruding component is mounted, and in which an adjusting assembly 8 is arranged;

[0053] A reciprocating screw 4 is fixedly mounted on the lower end of the rotating cylinder 3, and a stirring assembly 6 is arranged on the reciprocating screw 4. The stirring assembly 6 includes a sliding block 61 installed on the reciprocating screw 4 through a ball nut, and a connecting component is installed between the sliding block 61 and the feeding cylinder 57. A stirring mechanism is installed on the feeding cylinder 57, and an annular groove 622 is provided on the feeding cylinder 57. Balls 66 uniformly distributed in an annular shape are slidably installed on the annular groove 622, and a sealing disk 65 is fixedly installed between the balls 66. A rotating shaft 67 is sealed and penetrated and rotatably installed on the sealing disk 65, and one end of the rotating shaft 67 is penetrated and rotatably installed on the feeding cylinder 57, and a stirring rod 68 is fixedly installed on the rotating shaft 67, and a monitoring assembly 7 is arranged on the stirring rod 68;

[0054] The monitoring assembly 7 includes a connecting rod 74 fixedly mounted on the sealing disk 65, a fixing box 75 fixedly mounted on the connecting rod 74, and the fixing box 75 is rotatably connected to the stirring rod 68, a monitoring component is installed in the fixing box 75, and a cleaning component is installed in the fixing box 75.

[0055] like Figure 1 - Figure 5 As shown, the feeding component includes a storage barrel 51 fixedly mounted on the kettle body 1, a disc 53 is rotatably mounted on the rotating barrel 3, a conduit 52 is fixedly connected between the disc 53 and the storage barrel 51, and the conduit 52 penetrates and is fixedly mounted on the kettle body 1, a sealing ring 54 is rotatably mounted in the disc 53, a tube body 55 is fixedly connected to the rotating barrel 3, and one end of the tube body 55 is sealed and penetrates and is fixedly mounted on the sealing ring 54;

[0056] The rotating cylinder 3 is fixedly connected with a feeding pipe 58 , two of which are provided, and both feeding pipes 58 are sealed and penetrate and fixedly installed on the feeding cylinder 57 , and the feeding cylinder 57 is fixedly connected with a spraying pipe 59 , two of which are provided.

[0057] The extrusion component includes a fixed block 510 fixedly installed on the inner bottom wall of the feeding barrel 57, and two fixed blocks 510 are provided. A two-way electric telescopic rod 511 passes through and is fixedly installed on the fixed block 510 on one side, and an extrusion plate 512 is fixedly installed on the two-way electric telescopic rod 511. There are two extrusion plates 512, and elastic baffles 514 are fixedly installed on the two extrusion plates 512. An elastic sealing plate 513 is fixedly installed in the feeding barrel 57, and the two extrusion plates 512 are fixedly connected to the elastic sealing plate 513. A limiting rod 515 is fixedly installed on the fixed block 510 on the other side. There are two limiting rods 515, and the two limiting rods 515 are fixedly connected to the corresponding extrusion plates 512.

[0058] The connecting component includes a slide groove 62 provided on the slide block 61 , on which slide blocks 63 evenly distributed in an annular shape are slidably mounted, and the slide blocks 63 are all fixedly connected to the feed barrel 57 .

[0059] When the device is needed, solid materials are first fed into the kettle body 1 through the existing feeding equipment, and liquid materials are fed into the storage barrel 51, and then the electric valve (not shown) on the guide tube 52 is activated, so that the liquid materials in the storage barrel 51 enter the rotating barrel 3 along the guide tube 52, the disc 53 and the tube body 55, and finally enter the supply barrel 57 along the two feeding pipes 58, and gather on both sides of the two extrusion plates 512 (such as Figure 4 direction shown).

[0060] When the material storage barrel 51 is feeding the material into the material supply barrel 57, the mixing motor 2 and the bidirectional electric telescopic rod 511 are started. The operation of the bidirectional electric telescopic rod 511 will drive the two extrusion plates 512 to intermittently move away from and approach each other. When the two extrusion plates 512 move away from each other, the corresponding elastic baffles 514 will move together and cooperate to stretch the two sides of the elastic blocking plate 513. When the two elastic baffles 514 are tightly fitted with the side walls of the material supply barrel 57 and cooperate with the elastic blocking plate 513, the material supply barrel 57 is divided into two upper and lower areas (such as the upper and lower areas). Figure 4 When the two extrusion plates 512 continuously move away from each other, the material collected at the lower end of the feed barrel 57 (i.e., Figure 5As shown, the elastic sealing plate 513 and the liquid material below the two elastic baffles 514 are subjected to a certain extrusion pressure, and the liquid material is sprayed out through the two spray pipes 59, which can help reduce the resistance exerted by the solid material on the liquid material when the liquid material is injected into the solid material, help to increase the contact area between the liquid material and the solid material, and improve the uniformity of the injection of the liquid material into the solid material.

[0061] When the two squeezing plates 512 cooperate to squeeze the liquid material at the lower end of the feeding barrel 57, the liquid material inside the feeding barrel 57 can be intermittently sprayed into the solid material through the continuous cooperation of the two-way electric telescopic rod 511 and the two elastic baffles 514, the two squeezing plates 512, and the elastic sealing plate 513.

[0062] The bidirectional electric telescopic rod 511 has a bidirectional telescopic function. When the bidirectional electric telescopic rod 511 is running, both ends of the rod can be extended or retracted, and driving force can be provided in two symmetrical directions at the same time. Its internal structure and working principle are all existing mature technologies and will not be further elaborated here.

[0063] The two limit rods 515 can be stretched or compressed. When the bidirectional electric telescopic rod 511 drives the two extrusion plates 512 to move away from or towards each other, the two limit rods 515 can effectively improve the stability of the two extrusion plates 512 during the reciprocating movement under force.

[0064] At the same time, when the bidirectional electric telescopic rod 511 is running and the liquid material in the feeding barrel 57 is intermittently sprayed out, the operation of the mixing motor 2 will drive the rotating barrel 3 and the reciprocating screw 4 to rotate together. During the rotation process, the reciprocating screw 4 will make the feeding barrel 57 reciprocate up and down (such as Figure 2 In the direction shown, the rotating cylinder 3 can rotate with the feeding cylinder 57 through the connecting piece 56 during the rotation process. Therefore, the feeding cylinder 57 can be rotated while the liquid material inside the feeding cylinder 57 is injected into the solid material by reciprocating up and down, which can effectively improve the uniformity of the overall mixing of the liquid material and the solid material and increase the speed of the mixing reaction between the two.

[0065] Furthermore, the squeezing force applied to the liquid material inside the feed barrel 57 by the cooperation of the bidirectional electric telescopic rod 511 and the two squeezing plates 512 can not only effectively increase the contact area and contact uniformity between the liquid material and the solid material, but also effectively reduce the blocking of the two spray pipes 59 by the solid material or the solid-liquid mixture through the impact force generated when the liquid material is sprayed out, thereby effectively ensuring the spraying speed and effect of the two spray pipes 59.

[0066] Two feeding pipes 58 are provided, both of which are made of elastic material. When the reciprocating screw 4 drives the feeding barrel 57 to move back and forth up and down through the sliding block 61 and multiple sliders 63, that is, the feeding barrel 57 gradually moves away from or approaches the rotating barrel 3, the two feeding pipes 58 themselves can be stretched or compressed. The stability of the liquid material inside the rotating barrel 3 being input into the feeding barrel 57 through the two feeding pipes 58 can be ensured during this process. At the same time, the connecting piece 56 consists of a circular ring and two telescopic rods. The circular ring is fixedly mounted on the rotating barrel 3, and the two telescopic rods are fixedly mounted between the circular ring and the feeding barrel 57. When the feeding barrel 57 is forced to move back and forth up and down, the two telescopic rods will be stretched or compressed. At this time, the two telescopic rods can ensure that the feeding barrel 57 always maintains a rotating state when the force is vertical.

[0067] like Figure 2 , Figure 3 , Figure 6 - Fig.10 As shown, the stirring mechanism includes an annular rack 64 fixedly mounted on the sliding block 61, a rotating rod 69 is sealed and penetrated and rotatably mounted on the feeding barrel 57, a stirring rod 2 610 is fixedly mounted on the rotating rod 69, a rotating gear 611 meshing with the annular rack 64 is fixedly mounted on the rotating rod 69 and the rotating shaft 67, a fixing member 612 is fixedly mounted on the feeding barrel 57, two fixing members 612 are provided, shafts 615 are penetrated and rotatably mounted on the two fixing members 612, mixing plates 617 are fixedly mounted on the two shafts 615, and a transmission component is installed on the feeding barrel 57;

[0068] A parallel axis gear 618 is fixedly mounted on both fixing members 612, a roller body 619 is fixedly mounted on the lower end of the reciprocating screw rod 4, a support member 620 is fixedly mounted on the roller body 619, a gear bar 621 is fixedly mounted on the support member 620, two gear bars 621 are provided, and both gear bars 621 cooperate with the corresponding parallel axis gear 618.

[0069] The transmission component includes a placement groove 623 opened on the feed barrel 57, and two placement grooves 623 are provided, and the annular groove 622 is connected to the left placement groove 623 (the left and right here refer to Fig.10 , Fig.10 The annular groove 622 in the figure is the left side), the two placement grooves 623 are rotatably mounted with round rods 613, the two round rods 613 are fixedly mounted with spur gears 1, the two shaft rods 615 are fixedly mounted with spur gears 2 meshing with the corresponding spur gears 1, elastic partitions 616 are fixedly mounted between the two shaft rods 615 and the corresponding placement grooves 623, and driving wheels (drawn but not marked in the figure, from Figure 8 As can be seen in the figure), driven wheels (drawn but not marked in the figure) are fixedly mounted on the two round rods 613. Figure 8As can be seen in the figure, a conveyor belt 614 is installed between the two driving wheels and the corresponding driven wheels.

[0070] When the feeding cylinder 57 is rotated by force and moves up and down (such as Figure 2 When the liquid material inside the kettle body 1 is intermittently and evenly sprayed into the solid material, the stirring rod 1 68, the stirring rod 2 610 and the two mixing plates 617 rotate together with the feeding cylinder 57, and reciprocate up and down to mix and stir the solid and liquid materials inside the kettle body 1, which can help to improve the uniformity of the overall mixing of the solid and liquid materials.

[0071] At the same time, the sliding block 61 is driven by the force to drive the feeding cylinder 57 to move up and down (such as Figure 3 As shown in the direction, the feed barrel 57 is forced to rotate relative to the sliding block 61, that is, when the rotating shaft 67 and the rotating rod 69 rotate relative to the sliding block 61, the cooperation between the annular rack 64 and the two rotating gears 611 can make the rotating shaft 67 and the rotating rod 69 rotate along the sliding block 61 at the same time (when the rotating gear 611 moves on the annular rack 64, the teeth on the rotating gear 611 mesh with the teeth on the annular rack 64, and the annular rack 64 will apply a force to the teeth of the rotating gear 611. When the rotating gear 611 is forced to rotate along the annular trajectory of the annular rack 64, due to the meshing method and the direction of the force, a component force will be generated in the axial direction of the rotating gear 611, and this component force will cause the rotating gear 611 to rotate. 611 rotates), and while the rotating shaft 67 and the rotating rod 69 drive the stirring rod 1 68 and the stirring rod 2 610 to rotate to further mix and stir the solid and liquid materials, the two round rods 613 can be rotated accordingly through the cooperation of the corresponding driving wheel, the conveyor belt 614 and the driven wheel. When the two round rods 613 rotate, they will drive the two shafts 615 and the two mixing plates 617 to rotate through the cooperation of the corresponding spur gear 1 and the spur gear 2, so as to further mix and stir the solid and liquid materials, thereby further improving the uniformity of the mixing of the solid and liquid materials, further improving the sufficiency of the contact between the solid and the liquid, and helping to improve the pH uniformity of the mixed materials of the two, as well as the effect and efficiency of the material mixing reaction.

[0072] When the mixing motor 2 drives the rotating cylinder 3 and the reciprocating screw 4 to rotate together, the roller body 619, the support member 620, and the two gear bars 621 will rotate together. When the reciprocating screw 4 cooperates with the sliding block 61 to drive the feeding cylinder 57 to move downward (such as Fig. 9 When the two parallel shaft gears 618 on the feeding barrel 57 are respectively meshed with the corresponding gear bars 621, the two gear bars 621 cooperate with the corresponding parallel shaft gears 618, so that the two fixing members 612 can drive the corresponding shaft rods 615 and the mixing plate 617 to rotate downward relatively (as shown in the direction). Fig. 9In the direction shown, two parallel shaft gears 618 are arranged with tooth surfaces facing oppositely, that is, the tooth surface of one parallel shaft gear 618 faces upward and the tooth surface of the other faces downward, and the tooth blocks on the two gear bars 621 are meshed with the corresponding parallel shaft gear 618). At this time, the feed cylinder 57 is rotated downward by force, so that the two mixing plates 617 can mix and stir the solid and liquid materials at the lower end of the kettle body 1, thereby further ensuring the uniformity of the mixing of the solid and liquid materials inside the kettle body 1 as a whole, and further improving the accuracy and stability of the subsequent acid-base sensor 79 in monitoring the pH value of the solid-liquid mixture.

[0073] from Figure 2 It can be seen that in order to facilitate the subsequent discharge of all materials inside the kettle body 1, the lower end of the kettle body 1 is set to be arc-shaped. At this time, the two mixing plates 617 with variable stirring angles can effectively ensure the effect of the equipment on mixing and stirring the solid and liquid materials at the lower end of the kettle body 1 and above the arc surface, thereby reducing the occurrence of stirring dead corners in the process of mixing and stirring the solid and liquid materials inside the kettle body 1.

[0074] When the two fixing members 612 are driven by the force to drive the corresponding shaft rods 615 and mixing plates 617 to rotate downward relative to each other (such as Figure 8 The ends of the two shafts 615 located on the corresponding round rods 613 will rotate upward (as shown in the direction). Figure 8 In the direction shown, that is, the two shafts 615 drive the corresponding spur gear 2 to gradually move away from the corresponding spur gear 1. At this time, when the rotating shaft 67 and the rotating rod 69 cooperate to drive the two round rods 613, the corresponding shaft 615 and the mixing plate 617 will not be driven to rotate together. That is, the two mixing plates 617 will only cooperate with the reciprocating screw rod 4 as the axis to rotate and mix the solid and liquid materials at the lower end of the kettle body 1.

[0075] When the feeding cylinder 57 is driven by the force to drive the stirring rod 1 68, the stirring rod 2 610 and the two mixing plates 617 to move upward (such as Fig. 9 The two shafts 615 and the two mixing plates 617 can be driven to rotate upward and reset (as shown in the direction) through the cooperation of the two gear bars 621 and the corresponding parallel axis gear 1 618. Fig. 9 The two round rods 613 drive the corresponding shaft rods 615 and the mixing plate 617 to rotate and mix the solid and liquid materials.

[0076] At the same time, the two elastic partitions 616 can be used to block the corresponding placement grooves 623, thereby effectively preventing the solid-liquid mixture inside the kettle body 1 from entering the feeding barrel 57 and damaging or hindering the operation of the internal components of the feeding barrel 57. In addition, when the two shafts 615 are forced to rotate upward or downward (such as Figure 8The two elastic partitions 616 can be compressed or stretched by their own elasticity.

[0077] like Fig.11 - Fig.15 As shown, the monitoring component includes a reset spring 77 fixedly installed on the inner top wall of the fixed box 75, and two reset springs 77 are provided. A support plate 78 is fixedly installed between the two reset springs 77, and an acid-base sensor 79 is fixedly installed on the lower end of the support plate 78. The acid-base sensor 79 is sealed and penetrated and slidably installed on the fixed box 75.

[0078] The cleaning component includes a limit box 711 fixedly mounted at the lower end of the support plate 78, and there are two limit boxes 711. A weighted ball 712 is placed in each of the two limit boxes 711, and there are two weighted balls 712. An annular scraper 710 that cooperates with the acid-base sensor 79 is fixedly mounted at the lower end of the fixed box 75. A cleaning plate 76 is fixedly mounted on the stirring rod 68, and there are two cleaning plates 76. A parallel axis gear 2 73 is fixedly mounted on the sealing disk 65. A fixed frame 71 is fixedly mounted on the rotating cylinder 3, and a first rack 72 that cooperates with the parallel axis gear 2 73 is fixedly mounted on the fixed frame 71.

[0079] The adjusting component 8 includes an alkali liquid buffer box 81 fixedly mounted on the feeding barrel 57, an acid liquid buffer box 82 fixedly mounted on the feeding barrel 57, a liquid supply pipe 83 is fixedly connected to the alkali liquid buffer box 81 and the acid liquid buffer box 82, a liquid replenishment pipe 84 is sealed and passed through and fixedly mounted on the kettle body 1, two liquid replenishment pipes 84 are provided, and the two liquid replenishment pipes 84 are matched with the corresponding liquid supply pipes 83, the lower ends of the alkali liquid buffer box 81 and the acid liquid buffer box 82 are fixedly connected with a connecting pipe 85, and the two connecting pipes 85 pass through and are fixedly mounted on the feeding barrel 57, and a sealing component is provided in the feeding barrel 57.

[0080] The blocking component includes a transmission rod 812 rotatably mounted on the inner wall of the feed barrel 57, an adjustment plate 814 is fixedly mounted on the transmission rod 812, and a limit plate 86 is fixedly mounted on the inner wall of the feed barrel 57. Two limit plates 86 are provided, and a blocking rod 87 is penetrated and slidably mounted on both limit plates 86. The upper ends of the two blocking rods 87 are sealed and slidably mounted in the corresponding connecting pipes 85, and the lower ends of the two blocking rods 87 are both in contact with the upper end of the adjustment plate 814.

[0081] A positioning plate (not shown in the figure but not labeled) is fixedly mounted on the top wall of the feed cylinder 57. Fig.15 As can be seen in the figure, a motor 88 is fixedly mounted on the positioning plate, a threaded rod 89 is fixedly mounted on the driving end of the motor 88, a moving block 810 is threadedly mounted on the threaded rod 89, a second rack 811 is fixedly mounted on the moving block 810, and a parallel axis gear 813 meshing with the second rack 811 is fixedly mounted on the transmission rod 812.

[0082] When the stirring rod 1 68, the stirring rod 2 610 cooperates with the two mixing plates 617 to mix and stir the solid and liquid materials in the kettle body 1 for a period of time, after the solid and liquid materials are evenly mixed, the acid-base sensor 79 is started. The operation of the acid-base sensor 79 can automatically monitor the pH value of the solid-liquid mixed material in the kettle body 1, and in the process of the stirring rod 1 68 rotating under force and moving up and down reciprocatingly (such as Fig.11 The acid-base sensor 79 will rotate along with the kettle body 1, thereby enabling the acid-base sensor 79 to monitor the pH value of the solid-liquid mixture inside the kettle body 1 in all directions, which helps to improve the uniformity of the acid-base sensor 79 in monitoring the overall pH value of the solid-liquid mixture inside the kettle body 1, as well as the accuracy of the monitoring results.

[0083] During the mixing reaction of solid and liquid materials inside the kettle body 1, different products will be generated under different pH conditions (i.e., different acid-base conditions). Therefore, during the mixing reaction of solid and liquid materials, the pH value of the solid-liquid mixture needs to be monitored in real time. At the same time, during the mixing reaction of solid and liquid materials, there will be different reaction rates within different pH ranges. In addition, during the mixing reaction of solid and liquid materials, when the pH value of the solid-liquid mixture is too low or too high (when the solid-liquid mixture is acidic or alkaline), the final reactants of the solid and liquid will decompose, precipitate or deteriorate, and the solid-liquid mixture at this time will easily corrode the inner wall of the kettle body 1, reducing the service life of the equipment. Therefore, the pH value of the solid-liquid mixture inside the kettle body 1 needs to be monitored in real time by the acid-base sensor 79, and the pH value of the solid-liquid mixture needs to be adjusted according to the monitoring results.

[0084] The working principle of the acid-base sensor 79 is similar to that of the existing pH sensor. It is mainly based on the interaction between the equipment and the hydrogen ions in the material, and measures the pH of the material through electrodes that generate a potential difference. Its specific working principle and internal components are all existing technologies and will not be further elaborated here. In addition, in order to ensure the stability of the acid-base sensor 79 when it is rotated and reciprocated up and down inside the kettle body 1, and to monitor the solid-liquid mixture inside the kettle body 1 in an all-round and uniform manner, a wireless acid-base sensor 79 is required. During operation, the acid-base sensor 79 can send monitoring data to the receiving device in real time through existing mature wireless communication technology.

[0085] At the same time, the stirring rod 68 drives the acid-base sensor 79 to monitor the pH value of the solid-liquid mixture in the kettle body 1 in all directions. During the self-rotation of the stirring rod 68, the two cleaning plates 76 will rotate together. At this time, the sealing disk 65 and the connecting rod 74 limit the position of the fixed box 75 and the acid-base sensor 79, so that the two cleaning plates 76 can intermittently clean the lower end of the acid-base sensor 79 (such as Fig.13In the direction shown, the portion of the acid-base sensor 79 located outside the fixed box 75 is a monitoring probe), which can help improve the accuracy of monitoring the pH value of the mixed material in different areas of the kettle body 1 during the process of the acid-base sensor 79 rotating under force and moving back and forth up and down.

[0086] When the reciprocating screw rod 4 drives the feed cylinder 57 and the sealing disk 65 upward through the sliding block 61 (such as Fig.11 When the parallel axis gear 2 73 on the sealing disk 65 meshes with the first rack 72, the first rack 72 cooperates with the parallel axis gear 2 73, so that the sealing disk 65 drives the fixed box 75 and the acid-base sensor 79 to rotate through the connecting rod 74. When the fixed box 75 drives the acid-base sensor 79 to rotate upward and perpendicular to the stirring rod 1 68 (as shown in the direction ... Fig.12 In the direction shown), at this time, under the action of the self-gravity of the support plate 78 and the acid-base sensor 79, the two reset springs 77 will be compressed downward, so that the monitoring probe at the lower end of the acid-base sensor 79 gradually enters into the fixed box 75;

[0087] In this process, the weighted balls 712 inside the two limit boxes 711 will move downward under the action of gravity, thereby increasing the squeezing force of the support plate 78 on the two reset springs 77, so that the support plate 78 drives the acid-base sensor 79 to move downward quickly. In this process, the annular scraper 710 can scrape and clean the solid-liquid mixture adhered to the side wall of the monitoring probe of the acid-base sensor 79, thereby further improving the cleanliness of the monitoring probe at the lower end of the acid-base sensor 79 and improving the accuracy of the acid-base sensor 79 in continuously monitoring the pH value of the solid-liquid mixture. When the fixed box 75 is rotated downward to reset (such as Fig.12 The plurality of weighted balls 712 and the acid-base sensor 79 will gradually move downward and reset under the action of gravity, so that the acid-base sensor 79 can subsequently monitor the pH value of the mixed material inside the kettle body 1.

[0088] At the same time, when the acid-base sensor 79 moves downward to monitor the pH value of the solid-liquid mixture, the resistance exerted by the solid-liquid mixture on the acid-base sensor 79 makes it easy for the acid-base sensor 79 to enter the fixed box 75. At this time, the multiple weighted balls 712 can effectively increase the gravity of the acid-base sensor 79, reduce the tendency of the acid-base sensor 79 to move toward the fixed box 75, and ensure the stability of the acid-base sensor 79 when moving downward to monitor the pH value of the solid-liquid mixture.

[0089] If the acid-base sensor 79 detects that the pH value of the solid-liquid mixture as a whole or in a certain area is too low (i.e., the solid-liquid mixture is acidic), the acid-base sensor 79 will send a signal to the mixing motor 2 and the motor 88 to stop the mixing motor 2 and drive the motor 88 to rotate forward. At this time, the threaded rod 89 cooperates with the moving block 810 to drive the second rack 811 to move to the left (such as Fig.15 In the process of moving, the second rack 811 applies a driving force to the parallel axis gear 3 813, which can make the adjustment plate 814 rotate counterclockwise around the transmission rod 812 (as shown in the direction). Fig.15 In the direction shown), during this process, the left blocking rod 87 will move downward under the action of gravity until the upper end of the left blocking rod 87 is removed from the left connecting pipe 85, and the alkaline regulator cached in the alkali liquid buffer box 81 will flow into the feed barrel 57 through the corresponding connecting pipe 85 under the action of gravity, and will be sprayed into the solid-liquid mixture with the cooperation of the two-way electric telescopic rod 511 and the two extrusion plates 512.

[0090] If the acid-base sensor 79 detects that the pH value of the solid-liquid mixture as a whole or in a certain area inside the kettle body 1 is too high (i.e., the solid-liquid mixture is acidic), the acid-base sensor 79 will drive the motor 88 to reverse, so that the adjustment plate 814 rotates clockwise with the transmission rod 812 as the axis. At this time, the upper end of the right blocking rod 87 will gradually move away from the right connecting pipe 85 (such as Fig.15 The direction shown) allows the acidic regulator cached in the acid liquid buffer box 82 to flow into the feed barrel 57 and be sprayed into the solid-liquid mixture under the extrusion of the two extrusion plates 512. After that, the pH value of the solid-liquid mixture can be adjusted by mixing and stirring the stirring rod 1 68, the stirring rod 2 610 and the mixing plate 617.

[0091] And by setting the time for each operation and shutdown of the motor 88 (the length of the operation time of the motor 88 can be set according to the total amount of solid and liquid materials mixed in the kettle body 1 at a time, or the type of reactants finally required to be obtained from the solid-liquid mixture), it is possible to inject a certain amount of alkaline regulator or acid regulator into the solid-liquid mixture each time, that is, when the acid-base sensor 79 detects that the pH value of the solid-liquid mixture as a whole or a certain area inside the kettle body 1 is too low or too high, after the driving motor 88 runs for a period of time, the motor 88 will automatically drive the second rack 811 to move and reset and then shut down, that is, the regulation The plate 814 is rotated under force, so that the liquid cached in the alkaline solution buffer box 81 or the acid solution buffer box 82 flows into the feed barrel 57 for a period of time, and then the adjustment plate 814 rotates and resets, so that the upper ends of the two blocking rods 87 re-block the corresponding connecting pipes 85. In this way, each time the acid-base sensor 79 detects that the pH value of the solid-liquid mixture needs to be adjusted, an alkaline regulator or an acidic regulator can be quantitatively input into the solid-liquid mixture, which can effectively avoid the situation where too much alkaline regulator or acidic regulator is input into the solid-liquid mixture at a single time, which affects the reaction rate and effect of the solid-liquid mixture.

[0092] At the same time, when the adjustment plate 814 is rotated under force, the two limiting plates 86 limit the movement of the corresponding blocking rods 87, so that the two blocking rods 87 can only move upward or downward in the vertical direction, thereby effectively ensuring the blocking effect of the blocking rods 87 on the corresponding connecting pipes 85 after movement.

[0093] At the same time, valves (not shown in the figure but not marked) are installed on the two liquid supply pipes 83. Fig.14 As can be seen in the figure, when it is necessary to replenish the liquid in the alkali solution buffer box 81 and the acid solution buffer box 82, the feeding cylinder 57 can be driven by the cooperation between the rotating cylinder 3 and the reciprocating screw 4 to move the two liquid supply pipes 83 to the bottom of the corresponding liquid replenishment pipe 84 (as shown in the figure). Fig.14 The position shown in the figure) is then opened by opening the valves on the two liquid supply pipes 83 and injecting alkaline regulator into the alkali liquid buffer tank 81 and acidic regulator into the acid liquid buffer tank 82 through an external liquid replenishing device, so that the pH value of the solid and liquid mixture can be automatically adjusted during the subsequent operation of the equipment.

[0094] Instructions for use: When the device is needed, first use the existing feeding equipment to feed the solid material into the kettle body 1, and feed the liquid material into the internal buffer of the storage barrel 51, and then intermittently spray the liquid material into the solid material through the cooperation of the feeding component, the extrusion component, and the two spraying pipes 59. At the same time, start the mixing motor 2 during this process. At this time, through the cooperation of the rotating barrel 3 and the reciprocating screw 4, the feeding barrel 57 can be driven to drive the stirring rod 1 68, the stirring rod 2 610 and the two mixing plates 617 to rotate, and at the same time, the solid and liquid materials in the kettle body 1 are mixed and stirred by reciprocating movement up and down (such as Figure 8 In the process, the ring rack 64 cooperates with the two rotating gears 611 and the transmission parts, so that the stirring rod 1 68, the stirring rod 2 610 and the two mixing plates 617 can rotate to further mix and stir the solid and liquid materials, which can help to uniform the overall pH value of the solid-liquid mixture.

[0095] After the solid and liquid materials inside the kettle body 1 are mixed and stirred for a period of time, the pH value of the solid-liquid mixture can be monitored by starting the acid-base sensor 79. At the same time, the acid-base sensor 79 rotates together with the stirring rod 68 and moves back and forth up and down, so that the acid-base sensor 79 can evenly monitor the entire solid-liquid mixture in the kettle body 1. Through the cooperation of the cleaning component and the two cleaning plates 76, the intermittent automatic cleaning effect of the monitoring probe at the lower end of the acid-base sensor 79 can be achieved.

[0096] If the acid-base sensor 79 detects that the pH value of the solid-liquid mixture as a whole or in a certain area is too low (i.e., the solid-liquid mixture is acidic), the acid-base sensor 79 will drive the motor 88 to rotate forward, causing the adjustment plate 814 to rotate counterclockwise around the transmission rod 812 (e.g., Fig.15 As shown in the direction, the left blocking rod 87 is gradually moved away from the corresponding connecting pipe 85, and the alkaline regulator cached in the alkali liquid buffer box 81 flows into the feeding tube 57 and is sprayed into the solid-liquid mixture with the cooperation of the extrusion component. Conversely, the acid regulator in the acid liquid buffer box 82 can be sprayed into the solid-liquid mixture by the reverse rotation of the motor 88 and the cooperation of the extrusion component, thereby realizing automatic adjustment of the pH value of the solid-liquid mixture.

[0097] The above is only a preferred specific implementation of the present invention; however, 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 solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
