Description

Technical Field

[0001] The present invention relates to the technical field of corrosion inhibitor preparation, and specifically relates to a corrosion inhibitor preparation device and a preparation method thereof. Background Art

[0002] Scale and corrosion inhibitors are special chemical agents, mainly applied in water treatment systems such as cooling water and boiler water. They can prevent dissolved minerals and salts in water from forming deposits on the surfaces of equipment such as pipelines and heat exchangers. If these substances accumulate too much, it will affect the heat transfer efficiency of the equipment and may even block the pipelines, affecting the normal operation of the system. They can also slow down or prevent the corrosion of metal equipment in water. Since water usually contains a certain amount of oxygen, carbon dioxide and other corrosive substances, these substances may react with metals, causing equipment corrosion and damage. Scale and corrosion inhibitors can form a protective film on the metal surface or change the chemical properties of corrosive substances, thereby reducing the corrosion rate.

[0003] A Chinese patent with the authorization announcement number CN118698421B discloses a scale and corrosion inhibitor compounding and mixing device and a mixing method thereof, including a mixing tank and a tank cover. The tank cover is detachably arranged at the top opening of the mixing tank. An installation frame is fixed on the top side of the tank cover. A rotating cylinder extending downward into the mixing tank is rotatably arranged in the middle of the installation frame. A plurality of liquid injection frames are arranged around the outer circumference of the bottom end of the rotating cylinder, and a plurality of supply pipes corresponding to the liquid injection frames are arranged inside the rotating cylinder. The beneficial effects are as follows: By arranging a plurality of liquid injection frames and stirring frames that can swing up and down around the outer circumference of the rotating cylinder in this patent document, and using the liquid injection frames to respectively connect the supply pipes of a plurality of medicaments, the medicaments are continuously conveyed into the mixing tank during the stirring process through the liquid injection frames, so as to solve the problem that the overall pouring of medicaments in existing equipment is likely to cause stratification, improve the mixing and tumbling effect of the liquid in the mixing tank by the stirring frame, increase the shear force on the fluid, and make the liquid in the mixing tank in a turbulent state to improve the mixing uniformity.

[0004] In the preparation process of existing corrosion inhibitors, it is necessary to dissolve the preparation raw materials in a solution. However, existing preparation methods directly put the preparation raw materials into the solution, resulting in uneven distribution of the corrosion inhibitor raw materials in the solution, with local concentrations being too high or too low, reducing the dissolution effect of the corrosion inhibitor. Moreover, as the solution concentration gradually increases, the dissolution rate of the raw material particles decreases, and the raw materials will form lumps or precipitates in the solution and are more difficult to dissolve, increasing the reaction time. Summary of the Invention

[0005] The present invention provides a corrosion inhibitor preparation device and a preparation method thereof, aiming to solve the technical problems in the related art that in the preparation of existing corrosion inhibitors, the preparation raw materials need to be dissolved in a solution, but in the existing preparation methods, the preparation raw materials are directly put into the solution, resulting in uneven distribution of the corrosion inhibitor raw materials in the solution, with local concentration being too high or too low, reducing the dissolution effect of the corrosion inhibitor. Moreover, as the concentration of the solution gradually increases, the dissolution rate of the raw material particles decreases, and the raw materials will form lumps or precipitates in the solution and are more difficult to dissolve, increasing the reaction time.

[0006] A corrosion inhibitor preparation device of the present invention includes: a cylinder body, on which a feeding pipe coaxially arranged with it and having upper and lower openings is rotatably installed. Through holes are opened on the left and right opposite side walls of the feeding pipe.

The blocking member opens the opening at the bottom of the feeding pipe, and the blades will push the liquid downward, causing the liquid to enter the inside of the feeding pipe from the bottom of the feeding pipe. The liquid will flow out through the gap between the rotating cylinder and the mixing plate, forming a circulation, which can effectively prevent lumps or precipitates from settling at the bottom of the cylinder body or the feeding pipe, making the liquid have a circulating effect and improving the crushing effect on lumps or precipitates.

[0008] Preferably, the blocking member includes a second cylinder fixedly installed at the bottom of the cylinder body. The telescopic part of the second cylinder extends upward into the cylinder body and is in sealed sliding cooperation with the bottom wall of the cylinder body. A plug is fixedly installed on the telescopic part of the second cylinder.

[0009] Its effect is that the plug can control the closing of the opening at the bottom of the blanking pipe.

[0011] Its effect is that after the blade descends to the bottom, the sediment at the bottom is extruded into the interior of the blanking pipe, so that the sediment is extruded and crushed again to ensure the full mixing of the raw materials.

[0012] Preferably, a first cylinder is fixedly installed at the top of the cylinder body, a lifting plate is fixedly installed on the telescopic part of the first cylinder, a lifting rotating seat is rotatably installed on the lifting plate, the lifting rotating seat is sleeved on the outer side wall of the blanking pipe, and the lifting rotating seat is slidably connected along the axial direction of the blanking pipe.

[0013] Its effect is that it drives the two mixing plates to move towards each other horizontally from left to right.

[0014] Preferably, a driving gear is fixedly installed on the rotating cylinder, and racks meshing with one of the driving gears are installed on the mixing plates.

[0015] Its effect is that during the sliding process of the mixing plate, it drives the rotating cylinder to rotate.

[0019] Preferably, the upper end of the blanking pipe extends above the cylinder body, and a driving assembly for driving the blanking pipe to rotate is provided on the cylinder body.

[0020] A method for preparing a corrosion inhibitor, using the corrosion inhibitor preparation device described above, which includes the following steps:

[0021] Step 1: Add the material into the inside of the feeding pipe through the feeding pipe for dissolution;

[0022] Step 2: The feeding pipe drives the mixing plate to rotate to stir the liquid. The front and rear mixing plates continuously slide horizontally. The mixing plate will drive the rotating cylinder to rotate. After the raw material is dissolved, it enters the cylinder through the gap between the rotating cylinder and the mixing plate;

[0023] Step 3: The lumps accumulated inside the feeding pipe will enter the grooves formed on the rotating cylinder. As the rotating cylinder rotates, when the pressing plate reaches the pushing section of the pushing block, the pressing plate will be forced to extend to the outside of the rotating cylinder. The pressing plate will push the lumps in the grooves onto the mixing plate, thereby crushing the lumps;

[0024] Step 4: The blocking member opens the bottom opening of the feeding pipe.

As the rotating cylinder rotates, the lumps accumulated inside the feeding pipe will enter the grooves on the mounting holes. When the abutting plate on the pressing plate reaches the pushing section of the pushing block, the pressing plate will be forced to extend to the outside of the rotating cylinder. The pressing plate will push the lumps in the grooves onto the mixing plate, thereby crushing the lumps, which can effectively prevent the lumps from entering the liquid in the cylinder, so that the raw material can be completely dissolved in the liquid, effectively ensuring the uniformity of liquid mixing. The blocking member opens the bottom opening of the feeding pipe. The blade will push the liquid downward, so that the liquid enters the inside of the feeding pipe from the bottom of the feeding pipe. The liquid will flow out through the gap between the rotating cylinder and the mixing plate to form a cycle, which can effectively prevent the lumps or precipitates from settling at the bottom of the cylinder or the feeding pipe, making the liquid have a flowing effect and improving the crushing effect on the lumps or precipitates.

Detailed description of the specific implementation

[0043] The embodiments of the present invention will be described in detail below, and the examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0044] As Figures 1 to 14As shown in the figure, a specific embodiment of a corrosion inhibitor preparation device of the present invention includes a bearing module, a feeding module, a crushing and processing module, and a circulation module.

[0045] As Figure 1 shown in Figure 2 the figure, the bearing module includes a base 10 and a cylinder 11. The cylinder 11 is fixedly installed on the base 10, and the bottom of the cylinder 11 has a downwardly concave cavity 12, and the diameter of the cavity 12 is smaller than the diameter of the cylinder 11. The inside of the cylinder 11 is used for mixing raw materials and liquid.

[0046] As Figure 2 shown in Figure 3 and Figure 5 the figure, the feeding module includes a feeding pipe 20 and a driving motor 21. The feeding pipe 20 is rotatably installed in the cylinder 11, and the feeding pipe 20 is coaxially arranged with the cylinder 11. The upper end of the feeding pipe 20 extends above the cylinder 11, and the upper part of the feeding pipe 20 is an open structure. A driven gear is fixedly installed at the position of the feeding pipe 20 above the cylinder 11. A motor is installed on the upper surface of the cylinder 11, and a driving gear is installed at the output end of the motor. The driving gear meshes with the driven gear, so that the motor can drive the feeding pipe 20 to rotate continuously.

[0047] Through holes 24 are formed on the left and right opposite side walls of the feeding pipe 20. The through holes 24 on both sides correspond to each other, and the through holes 24 are located inside the cylinder 11. The crushing and processing module is installed at the through holes 24 on the cylinder 11. First, the liquid is injected into the inside of the cylinder 11 through the feeding pipe 20, and then the raw material particles are continuously added into the feeding pipe 20 through the opening above the feeding pipe 20. The raw material particles will be preliminarily dissolved in the feeding pipe 20. After the raw material particles are dissolved in the liquid, they will be evenly mixed into the liquid in the cylinder 11 through the through holes 24 on the feeding pipe 20. The materials that are not dissolved or form lumps inside the feeding pipe 20 will enter the cylinder 11 through the through holes 24 after being processed by the crushing and processing module. The working principle of the crushing and processing module will be described in detail below.

[0048] As Figure 3 shown in Figure 5 and Figure 6 and Figure 7 and Figure 8 and Figure 9 the figure, the crushing and processing module includes a mixing plate 40, a driving unit, a rotating cylinder 30, a fixed shaft 31, a connecting seat 32, an extrusion plate 33, a pushing spring 34, a pushing block 35, and an abutting plate 36.

[0049] There are two mixing plates 40 with the same structure arranged at intervals before and after in the through hole 24 of the blanking pipe 20. The mixing plate 40 is a square plate structure, and the two mixing plates 40 are horizontally slidably matched with each other in the through hole 24. That is, the front mixing plate 40 is slidably matched with the front side walls of the through holes 24 on the left and right sides, and the rear mixing plate 40 is slidably matched with the rear side walls of the through holes 24 on the left and right sides. The left and right ends of the two mixing plates 40 extend to the left and right sides of the blanking pipe 20, and there is a certain distance between the two ends of the mixing plate 40 and the inner wall of the cylinder body 11, so as to ensure that the two mixing plates 40 have enough moving space.

[0050] When the blanking pipe 20 rotates, it can drive the two mixing plates 40 to rotate at the same time. The mixing plate 40 can stir the liquid in the cylinder body 11 and play a mixing role. Through holes penetrating from front to back are formed in both of the two mixing plates 40, so that when the two mixing plates 40 rotate, the resistance can be reduced and the stirring efficiency can be improved at the same time.

[0051] As Figure 6 shown, the driving unit is used to drive the two mixing plates 40 to move, and the two mixing plates 40 move towards each other, that is, the moving directions of the two mixing plates 40 are opposite. The driving unit includes a first cylinder 43, a lifting plate 44, a lifting rotating seat 45 and a connecting rod 46.

[0052] The first cylinder 43 is fixedly installed at the top of the cylinder body 11. The telescopic part of the first cylinder 43 extends downward into the cylinder body 11, and the telescopic part of the first cylinder 43 is fixedly installed with a lifting plate 44. A circular lifting rotating seat 45 is rotatably installed at the central position of the lifting plate 44, and the lifting rotating seat 45 can rotate along its own axis. The lifting rotating seat 45 is sleeved on the outer side wall of the blanking pipe 20, and the lifting rotating seat 45 can slide along the axial direction of the blanking pipe 20. Thus, the blanking pipe 20 can continuously drive the lifting rotating seat 45 to rotate. When the first cylinder 43 drives the lifting plate 44 to lift, the lifting plate 44 can drive the lifting rotating seat 45 to lift along the blanking pipe 20.

[0053] Link rods 46 are rotatably installed on the left and right sides of the bottom of the lifting rotating seat 45 along the axis in the front-rear direction, and the two link rods 46 are respectively rotatably connected to the front and rear mixing plates 40. The two link rods 46 are both inclined and in a V shape. Thus, when the lifting plate 44 drives the lifting rotating seat 45 to descend, the included angle between the two link rods 46 increases, driving the front and rear mixing plates 40 to move to both sides respectively. For example, the front mixing plate 40 moves to the left and the rear mixing plate 40 moves to the right. It should be particularly emphasized that in the initial state, the two mixing plates 40 are arranged opposite to each other before and after.

[0054] As Figure 5 、 Figure 7 、 Figure 8 And Figure 9As shown in the figure, rotating cylinders 30 are rotatably installed in through holes 24 on the left and right sides of the blanking pipe 20. The axis of the rotating cylinder 30 is vertically arranged and parallel to the axis of the blanking pipe 20. The rotating cylinder 30 is located inside the front and rear mixing plates 40, and there is a certain gap between each rotating cylinder 30 and the front and rear mixing plates 40, so as to ensure that the raw material particles inside the blanking pipe 20 can be discharged from the gaps on both sides of the rotating cylinder 30 after dissolution. It should be emphasized that this gap is relatively small, only allowing liquid to pass through, and preventing particulate materials and agglomerated materials from passing through.

[0055] A driving gear 42 is fixedly installed at a position near the upper end of the rotating cylinder 30, and racks 41 are installed on both the front and rear mixing plates 40. The driving gear 42 on each rotating cylinder 30 meshes with the rack 41 on one of the mixing plates 40 respectively. Thus, when the two mixing plates 40 move left and right respectively, the two rotating cylinders 30 can be driven to rotate simultaneously.

[0056] A fixed shaft 31 coaxial with the rotating cylinder 30 is installed inside the rotating cylinder 30. The fixed shaft 31 is fixedly connected to the blanking pipe 20, and the rotating cylinder 30 is rotationally matched with the fixed shaft 31.

[0057] A plurality of mounting holes are evenly formed in the outer wall of the rotating cylinder 30 along its circumferential direction, and the mounting holes communicate with the inside of the rotating cylinder 30. Each mounting hole is slidably fitted with a pressing plate 33, and the pressing plate 33 can slide radially along the rotating cylinder 30. A pushing spring 34 is fixedly connected to the inner side surface of each pressing plate 33. A connecting seat 32 is rotationally installed on the fixed shaft 31 coaxially with it, and the end of the pushing spring 34 away from the pressing plate 33 is fixedly connected to the connecting seat 32. When the rotating cylinder 30 rotates, it will drive the pressing plate 33, the pushing spring 34 and the connecting seat 32 to rotate together.

[0058] A pushing block 35 is fixedly installed at a position near the middle of the fixed shaft 31. A contact plate 36 is fixedly installed at a position corresponding to the inner side of each pressing plate 33, and one end of the contact plate 36 abuts against the outer wall of the pushing block 35.

[0059] As Figure 8 shown, the cross-section of the pushing block 35 is a special-shaped structure. The pushing block 35 has a pushing section 37 and a recessed section 38, and the pushing section 37 and the recessed section 38 communicate with each other. The pushing section 37 is a semi-circular structure and faces the outside of the through hole 24 on the blanking pipe 20. The pushing section 37 is coaxially arranged with the fixed shaft 31. The recessed section 38 is two connected planes. The recessed section 38 is close to the inner side of the blanking pipe 20, and the two planes face the included angle between the rotating cylinder 30 and the front and rear mixing plates 40 respectively, and there is an arc transition between the two planes. That is to say, the distance from the axis of the recessed section 38 to the axis of the fixed shaft 31 is less than the distance from the axis of the pushing section 37 to the axis of the fixed shaft 31.

[0060] When the abutting plate 36 abuts against the recessed section 38 of the pushing block 35, the pressing plate 33 will be received into the mounting hole on the rotating cylinder 30, and a groove will be formed on the mounting hole. When the abutting plate 36 abuts against the pushing section 37 of the pushing block 35, the pressing plate 33 will extend out of the rotating cylinder 30.

[0061] The lumps that are not completely dissolved inside the blanking pipe 20 cannot pass through the gap between the rotating cylinder 30 and the front and rear mixing plates 40. Thus, the lumps will accumulate inside the blanking pipe 20 and at a position close to the gap. As the rotating cylinder 30 rotates, when the abutting plate 36 on the pressing plate 33 reaches the recessed section 38 of the pushing block 35, the pressing plate 33 is received into the mounting hole on the rotating cylinder 30, and a groove will be formed on the mounting hole. Thus, the lumps accumulated inside the blanking pipe 20 will enter the groove on the mounting hole. As the rotating cylinder 30 rotates, when the pressing plate 33 faces the mixing plate 40, that is, when the pressing plate 33 rotates to the front or the rear directly, at this time, the abutting plate 36 on the pressing plate 33 reaches the pushing section 37 of the pushing block 35, which will force the pressing plate 33 to extend out of the rotating cylinder 30. The pressing plate 33 will push the lumps in the groove onto the mixing plate 40, thereby crushing the lumps. At the same time, the movement of the mixing plate 40 will produce a rubbing effect on the lumps. The crushed lumps enter the inside of the cylinder body 11 after passing through the gap between the rotating cylinder 30 and the mixing plate 40, which can effectively prevent lumps from existing in the liquid inside the cylinder body 11.

[0062] During the process that the crushed lumps enter the cylinder body 11 after passing through the gap between the rotating cylinder 30 and the mixing plate 40, the front and rear mixing plates 40 are constantly moving, which is equivalent to constantly changing the stirring radius, improving the mixing effect, and at the same time can effectively improve the dissolution efficiency.

[0063] When the mixing plate 40 moves outward to the maximum stroke, the end of the mixing plate 40 can abut against the inner wall of the cylinder body 11, which can produce a scraping effect on the inner wall of the cylinder body 11 and prevent materials from adhering to the inner wall of the cylinder body 11.

[0064] As shown in Figure 2 、 Figure 4 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 and Figure 14 shown in

[0065] A plurality of circulation holes 23 are circumferentially formed on the outer side wall of the blanking pipe 20 near the bottom, and a bottom hole 22 is arranged at a position near the bottom of the bottom of the blanking pipe 20, and the bottom hole 22 is located below the through hole 24 on the blanking pipe 20.

[0066] A second cylinder 50 is fixedly installed at the bottom of the cylinder body 11. The telescopic part of the second cylinder 50 extends upward into the cylinder body 11 and is in sealed sliding fit with the bottom wall of the cylinder body 11. A plug 51 is rotatably installed on the telescopic part of the second cylinder 50. In this embodiment, the plug 51 has a cylindrical structure. When the second cylinder 50 drives the plug 51 to move up and down, the bottom hole 22 at the bottom of the blanking pipe 20 can be blocked and opened.

[0067] A sliding seat 60 is slidably fitted on the outer side wall of the blanking pipe 20 near the bottom along its axial direction. A connecting spring 61 is sleeved outside the blanking pipe 20, and the sliding seat 60 is connected to the blanking pipe 20 through the connecting spring 61. When the blanking pipe 20 rotates, the sliding seat 60 will rotate synchronously. It should be particularly noted that the sliding seat 60 is located inside the concave cavity 12.

[0068] A triangular mounting plate is provided on the outer side wall of the sliding seat 60. Blades 62 are rotatably installed on the three surfaces of the mounting plate through connecting shafts 63. The connecting shafts 63 are connected to the mounting plate through torsion springs, and the connecting shafts 63 are fixedly connected to the blades 62. It should be particularly emphasized that the elastic force of the torsion spring on the connecting shaft 63 is less than the elastic force of the connecting spring 61.

[0069] In the initial state, the three blades 62 are all in an inclined state. Each blade 62 has an arc section, a horizontal section, and two inclined sections. The two inclined sections connect the arc section and the horizontal section respectively (as Figure 11 ), and the connecting shaft 63 is installed on the horizontal section of the blade 62. The blanking pipe 20 will drive the blades 62 to rotate continuously, and the rotation of the blades 62 will generate a downward thrust on the liquid.

[0070] An opening for the connecting shaft 63 to pass through is provided on the blanking pipe 20. One end of the connecting shaft 63 extends to the inner side of the blanking pipe 20, and an adjusting surface 64 parallel to the blade 62 is provided at the end of the connecting shaft 63 located inside the blanking pipe 20. That is, when the blade 62 is in an inclined state, the adjusting surface 64 is also in an inclined state.

[0071] After working for a period of time, the lumps may settle at the bottom inside the blanking pipe 20, that is, at the position of the bottom hole 22. At this time, the second cylinder 50 can be driven to drive the plug 51 to descend to open the bottom hole 22. The blades 62 will push the liquid downward, so that the liquid passes through the circulation hole 23 and then enters the inside of the blanking pipe 20 again through the bottom hole 22. Then the liquid will flow out through the gap between the rotating cylinder 30 and the mixing plate 40 to form a circulation, thereby driving the lumps deposited at the bottom of the blanking pipe 20 to the gap between the rotating cylinder 30 and the mixing plate 40 for extrusion and crushing, avoiding the deposition of lumps at the bottom of the blanking pipe 20.

[0072] When the reaction between the raw material and the liquid reaches the final stage, the concentration of the liquid is relatively high at this time, and the dissolution rate of the raw material is slower. There may be precipitation in the concave cavity 12 at the bottom of the cylinder body 11. At this time, the second cylinder 50 drives the plug 51 to continue to descend, and the lower end surface of the plug 51 contacts the adjusting surfaces 64 on the three connecting shafts 63. Since the adjusting surfaces 64 are all in an inclined state consistent with the blades 62, by pushing the adjusting surfaces 64, the three blades 62 are forced to rotate simultaneously into a horizontal state (such as Figure 13 and Figure 14 ). The inclined sections on two adjacent blades 62 contact each other, causing the three blades 62 to form a disc structure, and its diameter is slightly smaller than the diameter of the concave cavity 12. Then the plug 51 continues to descend, causing the three blades 62 to descend until they reach the bottom. The connecting spring 61 will be stretched. After the three blades 62 descend to the bottom, the sediment at the bottom is extruded into the inner part of the blanking pipe 20 through the circulation holes 23. Based on the same principle as above, the sediment is extruded and crushed again to ensure the full mixing of the raw materials.

[0073] According to the corrosion inhibitor preparation device of the embodiment of the present invention, its preparation method includes the following steps:

[0074] Step 1, adding the material to the inside of the blanking pipe 20 through the upper end of the blanking pipe 20 for dissolution;

[0075] Step 2, the blanking pipe 20 drives the mixing plate 40 to rotate to continuously stir the liquid. At the same time, the first cylinder 43 drives the lifting and rotating seat 45 to continuously rise and fall, causing the front and rear mixing plates 40 to continuously slide horizontally. The mixing plate 40 will drive the rotating cylinder 30 to rotate. After the raw material is dissolved, it enters the cylinder body 11 through the gap between the rotating cylinder 30 and the mixing plate 40;

[0076] Step 3, the agglomerates gathered inside the blanking pipe 20 will enter the grooves formed on the mounting holes. As the rotating cylinder 30 rotates, when the extrusion plate 33 faces the mixing plate 40, the abutting plate 36 on the extrusion plate 33 reaches the pushing section 37 of the pushing block 35, which will force the extrusion plate 33 to extend outside the rotating cylinder 30. The extrusion plate 33 will push the agglomerates in the grooves onto the mixing plate 40, thereby crushing the agglomerates;

[0077] Step 4, the second cylinder 50 drives the plug 51 to descend, opening the bottom hole 22. The blades 62 will push the liquid downward, causing the liquid to enter the inside of the blanking pipe 20 through the bottom hole 22. Then the liquid will flow out through the gap between the rotating cylinder 30 and the mixing plate 40 to form a circulation, thereby driving the agglomerates deposited at the bottom of the blanking pipe 20 to the gap between the rotating cylinder 30 and the mixing plate 40 for extrusion and crushing, avoiding the deposition of agglomerates at the bottom of the blanking pipe 20.

[0078] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
