Description

Technical Field

[0001] This invention belongs to the field of stannous methanesulfonate crystal preparation technology, specifically relating to a washing device and method for preparing stannous methanesulfonate crystals. Background Technology

[0002] Stannous methanesulfonate, a white crystalline solid at room temperature, is widely used in electroplating and other electronic industries, including brush plating and bath plating, due to its stable plating solution, low corrosiveness, low toxicity, and low bubble production. However, during the production of stannous methanesulfonate crystals, a washing device is needed to remove surface impurities. Patent No. 202021926809.4 discloses a crystal washing and filtering device, consisting of a washing pot supported by a support frame, a stirring mechanism extending into the washing pot supported by a support base, and a filtering mechanism mounted on the top of the washing pot and extending into the washing pot above the stirring mechanism. During washing and filtering, the crystals are placed inside the filtering structure, and the stirring mechanism is controlled to agitate distilled water, accelerating its flow and removing impurities from the crystal surface. After washing, the filtering mechanism is removed, followed by the crystals. However, this device leaves distilled water residue on the crystal surface after washing, which spills onto the outer surface of the device after removal, requiring manual cleaning. Furthermore, a drying process is added after the crystals are removed, which is time-consuming and labor-intensive, and requires improvement. Summary of the Invention

[0014] A method of using a washing apparatus for preparing stannous methanesulfonate crystals includes the following steps:

[0015] S1: Unscrew the cover plate, add an appropriate amount of stannous methanesulfonate crystals into the filter box through the placement port, and tighten the cover plate.

[0016] S2: The third motor is started by the programmable controller. The output shaft of the third motor drives the second gear to rotate, which in turn drives the gear ring to rotate. The gear ring drives the filter box to rotate. Impurities on the surface of the stannous methanesulfonate crystals in the filter box are thrown into the upper body under the action of centrifugal force, achieving preliminary impurity removal. When the set time is up, the third motor is stopped by the programmable controller, and at the same time, the two second motors are started. The output shafts of the two second motors rotate in opposite directions, which in turn drive the two third drive shafts to rotate in opposite directions. The two third drive shafts drive the two first gears to rotate in opposite directions. During the reverse rotation of the two first gears, the two upper sealing plates move away from each other, and the two lower sealing plates move closer to each other, until the set time is reached and they stop. At this time, the filter box discharge port opens and the two impurity outlets open. The stannous methanesulfonate crystals enter the sorting chamber through the discharge port, and the impurities enter the impurity inlet pipe through the impurity outlet.

[0017] S3: The stannous methanesulfonate crystals entering the sorting chamber fall under their own gravity and are sorted by the first filter screens of different mesh sizes. After a set time, the programmable controller activates the fourth motor. The fourth motor drives the output shaft to rotate forward, causing the first conical wheel to rotate forward. The first conical wheel drives the second conical wheel to rotate forward, which in turn drives the connected first drive shaft to rotate forward. The first drive shaft drives the connected third gear, first pulley, and first filter screen to rotate. The connected first pulley drives the first transmission belt to rotate via friction transmission. The first transmission belt drives other first pulleys to rotate via friction transmission, and the other first pulleys drive the connected third gear, first pulley, and first filter screen to rotate. When one drive shaft rotates, other first drive shafts drive the connected third gear and first filter screen to rotate. During the rotation of the third gear, the second rack moves downward, and the second rack moves the fourth support plate in the same direction. The fourth support plate moves the partition in the same direction and stores it in the storage slot. The first drive shaft drives the first filter screen to rotate. When the set time is up, the partition is stored in the storage slot and the inclined bottom end of the first filter screen is flush with the lower conveying housing. That is, the stannous methanesulfonate crystals on the first filter screen roll down between the corresponding lower and upper conveying housings. The programmable controller controls the fifth motor on the lower and upper conveying housings to start. The fifth motor drives the third conical wheel to rotate. The wheel drives the fourth conical wheel to rotate, which in turn drives the connected second drive shaft to rotate. The second drive shaft then drives the connected washing roller and second pulley to rotate. The second pulley, through friction transmission, drives the connected second transmission belt to rotate. This second transmission belt, through friction transmission, drives other second pulleys to rotate. These other second pulleys then drive the connected second drive shaft to rotate, which in turn drives the connected washing roller to rotate. This achieves the unidirectional rotation of multiple washing rollers on the lower and upper conveyor housings, transporting the stannous methanesulfonate crystals along the inner wall curves of the lower and upper conveyor housings. When the stannous methanesulfonate crystals are in the front rectangular cavity, they... The programmable controller controls the start of the first air pump. The first air pump draws air to create a negative pressure state in the filter, the first impurity collection box, and the air inlet pipe. This draws the impurities removed from the stannous methanesulfonate crystals by the washing rollers into the first impurity collection box and into the impurity inlet pipe. When the stannous methanesulfonate crystals are in the middle trapezoidal cavity, distilled water and the washing rollers work together to clean the stubborn stains on the surface. When the stannous methanesulfonate crystals are in the rear rectangular cavity, the rolling washing rollers clean the distilled water remaining on the surface of the stannous methanesulfonate crystals. At the same time, the air from the outlet of the first air pump dries the stannous methanesulfonate crystals and the washing rollers through the outlet pipe and the air inlet. After the process is completed, the crystals fall into the collection box for collection.

[0018] S4: The second air pump is started by the programmable controller. The second air pump draws in the second impurity collection box and the impurity inlet pipe to form a negative pressure. The dust in the impurity inlet pipe enters the second impurity collection box and waits to be cleaned.

[0019] S5: If it is necessary to adjust the height of the upper conveyor housing during the above process, the programmable controller controls the first motor to start. The first motor drives the output shaft to rotate, which in turn drives the screw to rotate. During the rotation of the screw, the movable seat moves on the screw, which in turn moves the upper conveyor housing to achieve adjustment.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. This invention achieves the conveying, wet washing, and drying of stannous methanesulfonate crystals by rotating multiple washing rollers inside the upper and lower conveying housings. Compared with the prior art, it eliminates the need for workers to wipe the surface of the stannous methanesulfonate crystals to remove the water left by washing, saving time and effort. At the same time, multiple first filters are set up to self-sort the stannous methanesulfonate crystals before washing, reducing the workload of subsequent sorting by workers.

[0022] 2. The present invention provides a communication port between the first filter screen and the washing chamber, and a retractable partition is provided in the communication port. At the same time, a first driving mechanism is provided between the first filter screen and the retractable partition, which can realize the function of automatically retracting the retractable partition when the first filter screen flips and abuts against the lower conveying shell, so as to avoid affecting the filtration effect and facilitate the feeding between the upper and lower conveying shells.

[0023] 3. The filter box of this invention is set to be rotary and has an impurity outlet. Before being sorted, the stannous methanesulfonate crystals are centrifuged by rotation to remove surface impurities. At the same time, an adsorption mechanism is set in the rectangular cavity at the front of the washing chamber to remove surface impurities from the stannous methanesulfonate crystals before they are washed with water. This removes most of the surface impurities from the stannous methanesulfonate crystals before they are washed with water, thereby improving the recycling rate of the washing distilled water.

[0024] 4. The present invention provides a blowing mechanism in the rectangular cavity at the rear of the washing chamber, which can dry the stannous methanesulfonate crystal, improve the drying efficiency of the stannous methanesulfonate crystal, and at the same time dry the washing roller so that the washing roller can roll and wipe away the residual moisture on the surface of the stannous methanesulfonate crystal.

[0038] A method of using a washing apparatus for preparing stannous methanesulfonate crystals includes the following steps:

[0039] S1: Unscrew the cover plate 43, add an appropriate amount of stannous methanesulfonate crystals into the filter box 28 through the placement port 44, and tighten the cover plate 43.

[0040] S2: Stannous methanesulfonate crystals inside the filter housing 28 enter the sorting chamber 15 through the discharge port;

[0041] S3: The stannous methanesulfonate crystals entering the sorting chamber 15 fall under their own gravity and are sorted by the first filter screen 19 of different mesh sizes. After a set time, the programmable controller 5 controls the fourth motor 47 to start. The fourth motor 47 drives the output shaft to rotate forward, causing the first conical wheel 48 to rotate forward. The first conical wheel 48 drives the second conical wheel 49 to rotate forward. The second conical wheel 49 drives the connected first drive shaft 16 to rotate forward. The first drive shaft 16 drives the connected third gear 54, the first pulley 53, and the first filter screen 19 to rotate. The connected first pulley 53 drives the first transmission belt 50 to rotate via friction transmission. Belt 50 drives other first pulleys 53 to rotate via friction transmission. These first pulleys 53 drive the connected first drive shaft 16 to rotate. The first drive shaft 16 drives the connected third gear 54 and first filter screen 19 to rotate. During the rotation of the third gear 54, the second rack 51 moves downwards, causing the fourth support plate 52 to move in the same direction. The fourth support plate 52 then moves the partition 17 in the same direction, allowing it to be stored in the storage groove 18. The first drive shaft 16 drives the first filter screen 19 to rotate. When the set time is reached, the partition 17 is stored in the storage groove 18, and the inclined bottom end of the first filter screen 19 is flush with the lower conveying housing 24. The stannous methanesulfonate crystals roll down between the corresponding lower conveyor housing 24 and upper conveyor housing 25. The programmable controller 5 starts the fifth motor 57 on both the lower and upper conveyor housings. The fifth motor 57 drives the third conical wheel 58 to rotate, which in turn drives the fourth conical wheel 59. The fourth conical wheel 59 drives the connected second drive shaft 23 to rotate, which in turn drives the connected washing roller 22 and the second pulley 55 to rotate. The connected second pulley 55 drives the connected second transmission belt 56 to rotate via friction transmission, and the connected second transmission belt 56 drives the other second pulleys 55 to rotate via friction transmission. The other second pulleys 55 drive the connected second drive shaft 23 to rotate, and the connected second drive shaft 23 drives the connected washing roller 22 to rotate, so that the multiple washing rollers 22 on the lower conveying housing 24 and the upper conveying housing 25 can rotate in the same direction. The stannous methanesulfonate crystals are conveyed along the inner wall curve of the lower conveying housing 24 and the upper conveying housing 25. When the stannous methanesulfonate crystals are in the middle inverted trapezoidal cavity, the distilled water and the washing roller 22 work together to clean the stubborn stains on the surface. When the stannous methanesulfonate crystals are in the rear rectangular cavity, the rolling washing roller 22 cleans the distilled water remaining on the surface of the stannous methanesulfonate crystals. After the cleaning is completed, the crystals fall into the collection box 4 for collection. Example 2:

[0047] A method of using a washing apparatus for preparing stannous methanesulfonate crystals further includes the following steps:

[0048] S1: Before the stannous methanesulfonate crystals enter the sorting chamber 15, the third motor 42 is started by the programmable controller 5. The third motor 42 drives the output shaft to rotate, which in turn drives the second gear 41 to rotate. The second gear 41 drives the gear ring 45 to rotate, which in turn drives the filter box 28 to rotate. Impurities on the surface of the stannous methanesulfonate crystals in the filter box 28 are propelled through the filter box 28 into the upper body 1 by centrifugal force. When the set time is up, the programmable controller 5 stops the third motor 42 and simultaneously starts the two second motors 13. 13 Drive output shaft rotates in the opposite direction, driving two third drive shafts 34 to rotate in the opposite direction. The two third drive shafts 34 drive two first gears 36 to rotate in the opposite direction. During the reverse rotation of the two first gears 36, the two upper sealing plates 38 move away from each other, and the two lower sealing plates 33 move closer to each other until the set time is reached and they stop. At this time, the material inlet of the filter box 28 opens and the two impurity outlets 30 open. Stannous methanesulfonate crystals enter the sorting chamber 15 through the material inlet, and impurities enter the impurity inlet pipe 14 through the impurity outlet 30, thus achieving preliminary impurity removal.

[0049] S2: When the stannous methanesulfonate crystal is in the front rectangular cavity, the programmable controller 5 controls the first air pump 8 to start. The first air pump 8 draws and makes the filter 65, the first impurity collection box 64 and the air inlet pipe 63 present a negative pressure state, adsorbing the impurities cleaned off by the washing roller 22 into the first impurity collection box 64 and into the impurity inlet pipe 14.

[0050] S3: The second air pump 71 is started by controlling the programmable controller 5. The second air pump 71 draws to create a negative pressure in the second impurity collection box 66 and the impurity inlet pipe 14. The dust in the impurity inlet pipe 14 enters the second impurity collection box 66 and waits to be cleaned. Example 3:

[0051] The difference between this embodiment and embodiment 2 is that:

[0052] Specifically, the first air pump 8 is fixedly connected to the air outlet pipe 11, and the lower body 2 has multiple air inlets 26 at equal intervals between the lower conveying housing 24 and the upper conveying housing 25 located in the rectangular cavity at the rear of each washing chamber 3. The air inlets are connected to the air outlet pipe 11 and the washing chamber 3 at their respective ends.

[0053] A method of using a washing apparatus for preparing stannous methanesulfonate crystals further includes the following steps:

[0054] S1: Air from the outlet of the first air pump 8 is used to dry the stannous methanesulfonate crystal and the washing roller 22 through the outlet pipe 11 and the inlet 26. Example 4:

[0055] The difference between this embodiment and embodiment 3 is that:

[0056] Specifically, a lifting mechanism is installed between the upper conveying housing 25 and the lower body 2, extending from the outer section of the upper conveying housing 25. The lifting mechanism includes two first support plates 7 symmetrically fixed to the lower body 2 and a movable seat 12 fixed to the side wall of the upper conveying housing 25. A first motor 9 is fixed to the top of the upper first support plate 7. A screw 6 is placed between the two first support plates 7. One end of the screw 6 is connected to the output shaft of the first motor 9 through a coupling, and the other end of the screw 6 is connected to the inner wall of the lower first support plate 7 through a bearing. The movable seat 12 is connected to the screw 6 through a transmission nut. The first motor 9 is connected to the programmable controller 5 by wires.

[0057] A method of using a washing apparatus for preparing stannous methanesulfonate crystals further includes the following steps:

[0058] S1: If it is necessary to adjust the height of the upper conveying housing 25 during the above process, the programmable controller 5 controls the first motor 9 to start. The first motor 9 drives the output shaft to rotate, which in turn drives the screw 6 to rotate. During the rotation of the screw 6, the movable seat 12 moves on the screw 6, which in turn drives the upper conveying housing 25 to move to achieve adjustment.
