[0002] 5-Butylbenzotriazole is a new type of chemical material, widely used as corrosion inhibitor and rust inhibitor for metals (such as silver, copper, lead, nickel, zinc, etc.), mostly as a vapor phase corrosion inhibitor for copper and copper alloys. It is used as an outdoor coating additive to increase the brightness of plated parts and significantly reduce the fading of pigments (coatings) caused by ultraviolet damage. In addition, this product is also very common in rust-proof oil (grease) products, lubricant additives, circulating water treatment agents and automotive antifreeze. It can also be used in combination with a variety of scale inhibitors and bactericides and algaecides, and has a very good corrosion inhibition effect on closed-circulation cooling water systems.

[0003] A selective catalyst is required for the preparation of 5-butylbenzotriazole. The preparation steps of the selective catalyst are as follows: dispersing chitosan powder and dopamine hydrochloride in ammonia water, heating and stirring to react, drying after the reaction, mixing and grinding the dried product with urea, and calcining in an ammonia atmosphere to obtain an intermediate carrier; The pyridine-based ligand is dispersed in a toluene-ethanol mixed solvent to obtain a ligand solution, a metal chloride is added to the ligand solution, heated and stirred for reaction, an intermediate carrier is added, stirring is continued, and drying is performed to obtain a selective catalyst.

Due to the adsorption effect of the first magnet and the second magnet, the annular kit drives the inner annular scraper to slide on the inner wall of the "U"-shaped tube, thereby realizing the cleaning operation of the inner wall of the "U"-shaped tube.

The outer sides of the two grinding chambers 2 are sleeved with a spherical shell 3, the grinding chambers 2 are spherically arranged, the grinding chambers 2 rotate in the spherical shell 3, the spherical shell 3 slides on the frame 1 in a vertical direction, the upper ends of the grinding chambers 2 and the spherical shell 3 are both provided with openings, the lower end of the spherical shell 3 is connected with a discharge pipe 4, and the "U"-shaped tube 5 is connected to the conical mixing barrel 6, and the conical mixing barrel 6 is connected to the conical mixing barrel 6. The two pipe openings above the "U"-shaped tube 5 are respectively connected to the lower ends of the two spherical shells 3. The "U"-shaped tube 5 is sleeved on the outside of the corresponding discharge tube 4. The "U"-shaped tube 5 has an opening at the lower end. The conical mixing barrel 6 is located directly below the "U"-shaped tube 5. The connecting frame 7 is rotatably connected to the frame 1. The two main shafts 8 are rotatably connected to the connecting frame 7. The two airbags 9 correspond to the main shafts 8 one by one. The airbags 9 are connected to the upper ends of the main shafts 8. After the airbags 9 are inflated, they adapt to the inner wall of the grinding chamber 2. A plurality of elastic metal wires 11 are connected to the outer wall of the airbags 9.

[0030] The present invention provides two spherical grinding chambers 2. When preparing the selective catalyst, the obtained dry product and urea are ground separately. The grinding operations of the dry product and urea are performed separately. By providing a spherical grinding chamber, the powder particles are always at the bottom of the spherical grinding chamber 2, so that a full grinding operation can be achieved. The spherical setting has a stronger encapsulation property, and the powder particles can be effectively prevented from splashing during the grinding process. After the grinding operation is completed, the powder particles are poured out from the upper opening through the rotation operation of the grinding chamber 2, and the ground product falls into the spherical shell 3 and is introduced into the spherical shell 3 through the discharge pipe 4. The powder of the urea powder and the powder of the dry product are poured out, and the connecting frame 7 can be rotated to make the airbag 9 and the grinding component turn 180 degrees, and the airbag 9 is inflated to form a spherical airbag 9, and the spherical airbag 9 is fitted with the inner wall of the grinding chamber 2. When the main shaft 8 drives the airbag 9 to rotate, it also drives the elastic metal wire 11 to rotate, and then the inner wall of the grinding chamber 2 is scraped and cleaned, which effectively solves the problem of powder sticking after grinding.

[0031] Specifically, Figure 2-9As shown, it also includes two grinding assemblies 10, the two grinding assemblies 10 correspond to the main shaft 8 one by one, the grinding assembly 10 is connected to the lower end of the main shaft 8, and after the connecting frame 7 rotates 180 degrees, the position of the airbag 9 and the grinding assembly 10 is reversed. The grinding assembly 10 includes a grinding column 101, a connecting rod 103, two spring rods 104, two paddles 106 and a stopper 107. The grinding column 101 is fixedly connected to the lower end of the corresponding main shaft 8. A mounting groove 102 is opened on the grinding column 101. The lower end of the grinding column 101 is arranged in an arc. The lower end of the grinding column 101 cooperates with the inner wall of the grinding chamber 2. The connecting rod 103 is coaxially connected to the inside of the mounting groove 102 of the grinding column 101. The two spring rods 104 are provided with a plurality of spring plates 106, and the two spring plates 106 are provided with a plurality of spring plates 107. The rods 104 are rotatably connected to the connecting rod 103 through the rotating member 105, and the two dial plates 106 correspond to the spring rods 104 one by one. The dial plates 106 are connected to the ends of the spring rods 104, and the limit members 107 are connected to the connecting rods 103. The limit members 107 limit the rotation angles of the rotating member 105, the spring rods 104 and the dial plates 106. In the initial state, the dial plates 106 are retracted into the mounting grooves 102. Torsion springs are provided at the rotating connections of the rotating member 105. The rotation angle of one of the dial plates 106 is limited to 45 degrees by the limit members 107, and the rotation angle of the other dial plate 106 is limited to 90 degrees by the limit members 107. A slope is provided on the lower side of the mounting groove 102.

[0032] In the above embodiments, when the grinding operation is performed, the bottom of the grinding column 101 is matched with the spherical grinding chamber 2 to grind the material at the bottom of the spherical grinding chamber 2. During the rotation of the grinding column 101, due to the action of centrifugal force, the two spring rods 104 are extended, so that the paddle 106 is extended, and the paddle 106 is in contact with the inner wall of the spherical grinding chamber 2. During the rotation, the paddle 106 scrapes and pokes the material powder attached to the inner wall of the spherical grinding chamber 2, so as to achieve the operation of grinding and preventing sticking at the same time. The rotation angle of one paddle 106 is set to 45 degrees, and the rotation angle of the other paddle 106 is set to 90 degrees. Because the material is usually in the middle and lower position of the spherical grinding chamber 2, two paddles 106 set at different angles are used to effectively poke the sticky material.

[0033] Specifically, Figure 1 , Figure 2 , Figure 5 , Figure 6 and Fig.10As shown, it also includes a cleaning mechanism 12. Cleaning mechanisms 12 are provided on the pipes on both sides of the "U"-shaped tube 5. The cleaning mechanism 12 includes an annular scraper 121, a first magnet 122, an annular sleeve 123 and a second magnet 124. The annular scraper 121 fits against the inner wall of the "U"-shaped tube 5. The outer diameter of the discharge pipe 4 is smaller than the inner diameter of the annular scraper 121. The first magnet 122 is connected to both sides of the annular scraper 121. The annular sleeve 123 is slidably sleeved on the outer wall of the "U"-shaped tube 5. The second magnet 124 is connected to both sides of the annular sleeve 123. The first magnet 122 and the second magnet 124 attract each other.

[0034] In the above embodiments, by means of the cleaning mechanism 12, after the grinding is completed and the powder is poured out, the material attached to the inner wall of the "U"-shaped tube 5 is scraped off, thereby further improving the anti-adhesion effect, and the annular sleeve 123 can be pushed to slide on the outer wall of the "U"-shaped tube 5. Due to the adsorption effect of the first magnet 122 and the second magnet 124, the annular sleeve 123 drives the inner annular scraper 121 to slide on the inner wall of the "U"-shaped tube 5, thereby realizing the cleaning operation of the inner wall of the "U"-shaped tube 5.

[0035] Specifically, Figure 4-8 As shown, it also includes two sealing rings 13, multiple balls 14 and sealing grooves 15. The two sealing rings 13 correspond to the grinding columns 101 one by one. The sealing rings 13 are sleeved on the grinding columns 101. Multiple balls 14 are equidistantly embedded on the lower side of the sealing rings 13. A sealing groove 15 is opened at the upper end opening of the grinding chamber 2, and the balls 14 roll in the sealing groove 15.

[0036] In the above embodiments, when the main shaft 8 rotates to drive the grinding column 101 to rotate for grinding operation, the sealing ring 13 is close to the upper opening of the spherical grinding chamber 2, and the balls 14 on the sealing ring 13 roll in the sealing groove 15, thereby improving the rotation stability of the grinding column 101 and achieving a good sealing effect to prevent powder particles from overflowing from the upper opening.

[0037] Specifically, Figure 2 , Figure 3 and Figure 7As shown, it also includes multiple first friction wheels 16, support members 17, electric push rods 18, dual-axis motors 19, two second friction wheels 20 and two bevel gear sets 21. Each main shaft 8 is fixedly connected to a first friction wheel 16 on both sides. The first friction wheels 16 on both sides are symmetrically arranged along the rotating axis 27 of the connecting frame 7. The support member 17 is slidably connected to the frame 1 in the horizontal direction. The electric push rod 18 is connected to the frame 1. The output end of the electric push rod 18 is connected to the support member 17. The dual-axis motor 19 is connected to the support member 17. The two second friction wheels 20 are rotatably connected to both ends of the support member 17 respectively. The second friction wheels 20 drive the first friction wheels 16 and the corresponding main shaft 8 to rotate. The two bevel gear sets 21 link the two second friction wheels 20 with the dual-axis motor 19.

[0038] In the above embodiments, when the grinding operation is performed, the connecting frame 7 rotates so that the grinding column 101 is vertically downward. After the grinding column 101 enters the grinding chamber 2, the electric push rod 18 is operated to move the support member 17 and the two second friction wheels 20, so that the two second friction wheels 20 are engaged with the corresponding first friction wheels 16. The dual-axis motor 19 drives the bevel gear sets 21 on both sides to rotate the first friction wheel 16, thereby causing the main shafts 8 on both sides to rotate synchronously to perform the grinding operation. When the cleaning operation is performed after the grinding operation is completed, the connecting frame 7 rotates 180 degrees so that the airbag 9 faces downward. After the airbag 9 enters the spherical grinding chamber 2 and is inflated, it is engaged with the corresponding first friction wheel 16 through the second friction wheel 20, driving the airbags 9 on both sides to rotate synchronously to perform the cleaning operation.

[0040] In the above embodiment, when the first push-pull electromagnet 22 is pushed forward, it drives the first locking rod 23 to be inserted forward into the first locking hole 24, and locks the connecting frame 7 to improve the stability during grinding or cleaning operations. The second push-pull electromagnet 25 is pushed forward to realize the locking operation of the rotating shaft 27, thereby improving the stability of the grinding chamber 2 during grinding operations.

[0041] Specifically, Figure 2 , Figure 4 and Figure 5 As shown, it also includes a spur gear 29 and a rack 30. The spur gear 29 is connected to the rotating shaft 27, and the rack 30 is connected to the frame 1. After the spherical shell 3, the grinding chamber 2 and the rotating shaft 27 move downward, the rack 30 engages with the spur gear 29 to realize the flipping operation of the grinding chamber 2.

[0042] In the above embodiments, the turning operation and the downward movement operation of the grinding chamber 2 are linked by the spur gear 29 and the rack 30 .

[0043] Specifically, Figure 1 and Fig.11 As shown, it also includes two sliding frames 31, a scissor-type lifting frame 32 and a first motor 33. The two sliding frames 31 correspond to the spherical shell 3 one by one. The spherical shell 3 is slidably connected to the frame 1 through the sliding frames 31. The conical mixing barrel 6 is rotatably connected between the two sliding frames 31. The scissor-type lifting frame 32 is movably connected to the lower side of the frame 1. The scissor-type lifting frame 32 drives the two sliding frames 31 to move up and down synchronously. The first motor 33 is connected to the lower side of the frame 1. The output shaft of the first motor 33 is connected to a bidirectional screw rod 34. The first motor 33 drives the scissor-type lifting frame 32 through the bidirectional screw rod 34.

[0044] In the above embodiment, the operation of the first motor 33 drives the bidirectional screw rod 34 to rotate, thereby enabling the scissor-type lifting frame 32 to operate, and the scissor-type lifting frame 32 drives the two sliding frames 31 to achieve lifting, thereby realizing the lifting operation of the spherical shell 3, the grinding chamber 2, the "U"-shaped tube 5 and the conical mixing barrel 6.

[0045] Specifically, Figure 1 , Figure 2 and Fig.11 As shown, it also includes a rotating cylinder 35 and a second motor 36. The rotating cylinder 35 is connected to the frame 1. The output end of the rotating cylinder 35 is connected to the connecting frame 7. The rotating cylinder 35 drives the connecting frame 7 to rotate. The second motor 36 is connected to one of the sliding frames 31. The output shaft of the second motor 36 drives the conical mixing barrel 6 to rotate through the spur gear 29 group.

[0046] In the above embodiment, the rotary cylinder 35 drives the connecting frame 7 to rotate, thereby realizing the rotation of the connecting frame 7, and the second motor 36 drives the spur gear set 37 to operate, thereby driving the conical mixing barrel 6 to rotate to perform the mixing operation.

[0047] The working principle of the present invention is as follows: in the initial state, the grinding assembly 10 and the grinding chamber 2 are in a separated state, and the grinding chamber 2 is located at the lower position of the frame 1, but the spur gear 29 and the rack 30 are in a separated state, that is, the grinding chamber 2 is in an open upward state. When preparing the selective catalyst, the grinding column 101 is vertically downward, the first push-pull electromagnet 22 is operated, the first locking rod 23 is inserted into the first locking hole 24, and the connecting frame 7 is locked. The obtained dry product and urea are respectively placed in the two spherical grinding chambers 2, the first motor 33 is operated to drive the bidirectional screw rod 34 to rotate, so that the scissor-type lifting frame 32 operates, and the scissor-type lifting frame 32 drives the sliding frame 31 to move upward, so that the spherical shell 3, the grinding chamber 2, the "U"-shaped tube 5, and the conical mixing barrel 6 are all moved upward until the grinding column 101 enters the grinding chamber 2, the second push-pull electromagnet 25 is operated, and the second locking rod 26 is driven to move forward, and the second locking rod 26 is inserted into the second locking hole 28 on the rotating shaft 27, and the rotating shaft 27 and the two grinding chambers 2 are locked. Then, the electric push rod 18 is operated to push the support member 17 forward, so that the two second friction wheels 20 on the support member 17 are engaged with the corresponding first friction wheels 16, and the dual-axis motor 19 is operated to drive the bevel gear sets 21 on both sides, thereby synchronously driving the two grinding columns 101 to perform grinding operations. During the process of the grinding columns 101 rotating and grinding, due to the action of centrifugal force, the spring rod 104 extends, the paddle 106 extends, and the rotating member 105 rotates. Due to the action of the limit member 107, one of the paddles 106 rotates to a 45-degree position, and the other paddle 106 rotates to a 90-degree position, so that one side is realized. During grinding, the material is scraped and moved to prevent it from sticking. Since the material is usually in the middle and lower position of the spherical grinding chamber 2, the two-position paddle 106 can achieve a good paddle and scrape effect. When the grinding column 101 stops rotating, due to the torsion spring action of the spring rod 104 and the rotating member 105, the paddles 106 on both sides are retracted into the mounting groove 102, which facilitates the removal operation of the entire grinding assembly 10. During the grinding operation, the sealing ring 13 is at the upper end opening of the spherical grinding chamber 2, and the ball 14 rolls in the sealing groove 15 to achieve a good sealing operation. After the grinding is completed, the second locking rod 26 is separated from the second locking hole 28, the rotating shaft 27 is unlocked, and the grinding chamber 2, the spherical shell 3, the "U"-shaped tube 5 and the conical mixing barrel 6 are moved downward until the spur gear 29 is meshed with the rack 30, and the rotating shaft 27 is rotated to drive the two grinding chambers 2 to rotate, so that the opening of the grinding chamber 2 is downward, and the material powder falls out of the opening into the discharge pipe 4 of the spherical shell 3, and then is introduced into the "U"-shaped tube 5 through the discharge pipe 4, and the end cover of the conical mixing barrel 6 is opened to introduce the ground material into the conical mixing barrel 6; Before the mixing operation, the inner wall of the grinding chamber 2 and the inner wall of the "U"-shaped tube 5 can be cleaned, and the sticky part of the material can be cleaned into the mixing barrel. The first push-pull electromagnet 22 is operated to separate the first locking rod 23 from the first locking hole 24, and the rotating cylinder 35 is operated to rotate the connecting frame 7 by 180 degrees, so that the grinding column 101 and the airbag 9 are reversed, and the airbag 9 is directly below, so that the spherical grinding chamber 2 moves up, so that the airbag 9 enters the spherical grinding chamber 2, and the airbag 9 is connected to the external air source. The airbag 9 is inflated to form a spherical shape. After the connecting frame 7 is locked by the first locking rod 23, the electric push rod 18 and the double The shaft motor 19 causes the airbags 9 on both sides to rotate. The rotating airbags 9 drive the elastic metal wire 11 to rotate on the inner wall of the grinding chamber 2. The elastic metal wire 11 scrapes and cleans the inner wall of the grinding chamber 2 to clean part of the attached material powder, pushes the annular sleeve 123 to drive the annular scraper 121, so that the annular scraper 121 moves in the "U"-shaped tube 5 to clean the "U"-shaped tube 5, and then flips the grinding chamber 2 again to introduce the cleaned powder particles into the conical mixing barrel 6, and then runs the second motor 36 to drive the spur gear set 37, thereby causing the conical mixing barrel 6 to rotate for mixing operations.
