DETAILED DESCRIPTION

[0020] See also Figure 1-5 The utility model provides the following technical solutions: a pulping device for steel paper base paper production, comprising a mixing barrel 1, an electric stirring shaft 2 and a storage barrel 3, and also comprising a quantitative mechanism 4 and a flushing mechanism 5. A barrel cover 12 is provided on the top of the mixing barrel 1, and an electric stirring shaft 2 is installed on the barrel cover 12. Several storage barrels 3 are distributed in an annular manner on the barrel cover 12. Adjacent storage barrels 3 are connected by connecting pipes 31. Electric valves 1 34 are provided at both ends of the connecting pipe 31. A feed inlet 32 ​​is provided on the top of the side wall of the storage barrel 3. An electric valve 2 33 is provided at the bottom opening of the storage barrel 3. A mixing ring 55 is provided on the barrel cover 12. A feeding pipe 51 connected to the bottom opening of the storage barrel 3 is provided on the mixing ring 55. A rotating drum 52 is provided on the feeding pipe 51. A feeding groove 54 is opened on the rotating drum 52. A flushing groove 53 is provided on the side wall of the mixing ring 55. A quantitative mechanism 4 is installed on the storage barrel 3. A connecting valve 56 is provided on the mixing ring 55 and the connecting pipe 31.

[0021] The quantitative mechanism 4 includes an electric threaded rod 41, a marking block 42, a moving rod 43, a mounting plate 44 and a pressing plate 45. A pressing plate 45 is provided inside the storage barrel 3, a moving rod 43 is provided on the top of the pressing plate 45, and a scale is provided on the moving rod 43. A mounting plate 44 is provided on the barrel cover 12 and the mixing barrel 1, and an electric threaded rod 41 that cooperates with the moving rod 43 is installed on the mounting plate 44 located on the mixing barrel 1.

[0022] The mixing barrel 1 is used to prepare a variety of slurries, the electric stirring shaft 2 is used to stir the mixed slurries to ensure that different types of slurries can be mixed together, the storage barrel 3 is used to place different types of slurries, and the feed port 32 is used to feed the slurry into the storage barrel 3. The top of the mixing barrel 1 is provided with a barrel cover 12, which is convenient for the user to replace the electric stirring shaft 2. The slurry in the storage barrel 3 can be squeezed through the quantitative mechanism 4, so as to realize the quantitative feeding of the slurry, improve the efficiency and accuracy of the slurry preparation device, and when preparing the slurry, The connecting pipe 31 is opened, and the slurry is squeezed through the quantitative mechanism 4. The slurry in the storage barrel 3 enters the interior of the mixing barrel 1 through the connecting pipe 31 and the feeding pipe 51. The feeding pipe 51 and the feeding trough 54 are used to move the slurry. All the storage barrels 3 are connected through the cooperation of the connecting pipe 31. The electric valves 34 arranged at both ends of the connecting pipe 31 can prevent the slurry stored in the storage barrel 3 from mixing together during the storage process, which affects the working effect of the device. The connecting valve 56 arranged on the connecting pipe 31 and the matching of the connecting pipe 31 can prevent the slurry stored in the storage barrel 3 from mixing together during the storage process, which affects the working effect of the device. The cleaning water can be fed into the storage barrel 3, the connecting pipe 31 is opened, and the cleaning water entering the storage barrel 3 brings the remaining slurry in the storage barrel 3 into the mixing barrel 1, and then the electric stirring shaft 2 is started, and the electric stirring shaft 2 stirs the liquid in the mixing barrel 1, and then the valve on the discharge port of the mixing barrel 1 is opened to discharge the liquid in the mixing barrel 1, thereby completing the cleaning of the mixing barrel 1. The feed trough 54 is set on the rotating drum 52, and the user can control the rotating drum 52 to rotate to stir the slurry flowing in the feed trough 54. The moving direction of the liquid is adjusted. When the storage barrel 3 is cleaned separately, the drum 52 is rotated, and the cleaning water in the storage barrel 3 flows into the mixing liquid ring 55 from the feeding groove 54 through the flushing groove 53, and finally discharges the mixing liquid ring 55 through the connecting valve 56 provided on the mixing liquid ring 55, thereby completing the cleaning of the storage barrel 3. By adjusting the opening and closing of the connecting valve 56 for conveying cleaning water and the electric valves 34 at both ends of each connecting pipe 31, the number of storage barrels 3 cleaned by the device at the same time can be controlled, thereby improving the efficiency of the staff in cleaning the storage barrel 3;

[0023] The pressing plate 45 can squeeze the slurry in the storage barrel 3, thereby improving the efficiency of discharging the slurry in the storage barrel 3. The shape of the pressing plate 45 matches the storage barrel 3 to ensure the working effect of the pressing plate 45. The shape of the pressing plate 45 can also prevent the slurry in the storage barrel 3 from moving to the top surface of the pressing plate 45 during the squeezing of the pressing plate 45, which affects the working effect of the pressing plate 45. The shape of the pressing plate 45 ensures that the pressing plate 45 will scrape off the slurry attached to the inner wall of the storage barrel 3 during the movement, thereby ensuring the cleanliness of the inner wall of the storage barrel 3. The moving rod 43 is installed on the electric threaded rod 41 through a thread. When the electric threaded rod 41 is started, the moving rod 43 moves along the electric threaded rod 41 under the action of the thread. When the moving rod 43 moves, it will move with the pressing plate 45, thereby realizing the squeezing of the slurry in the storage barrel 3 by the pressing plate 45. The scale set on the moving rod 43 is convenient for the user to accurately adjust the moving distance of the pressing plate 45, so that the user can adjust the amount of slurry sent to the mixing barrel 1.

[0024] Specifically, the moving rod 43 is in a concave shape with an opening facing downward, and the length of one end of the moving rod 43 provided with a scale is greater than the length of the other end of the moving rod 43 .

[0025] The shape of the moving rod 43 ensures that the movement of the moving rod 43 will not be hindered. The scale of the moving rod 43 is set at the longer end of the moving rod 43, which is convenient for the user to confirm the moving distance of the moving rod 43.

[0026] Specifically, the bottom end of the longer end of the moving rod 43 is in the same plane as the bottom surface of the mounting plate 44 provided on the barrel cover 12 , and a marking block 42 matching the scale of the moving rod 43 is provided on the side wall groove of the mounting plate 44 provided on the barrel cover 12 .

[0027] The marking block 42 serves as a mark, which makes it easier for the user to determine the moving distance of the moving rod 43. The mounting plate 44 provided on the mounting ring 11 serves as a limiter, ensuring the stability of the moving rod 43 during the movement. The marking block 42 also serves as a limiter. The marking block 42 can prevent the moving rod 43 from moving along the side wall groove of the mounting plate 44 provided on the mounting ring 11 during the lifting process, thereby further improving the stability of the moving rod 43 during the movement.

[0028] Specifically, when the pressing plate 45 is located at the top, the feed port 32 is located below the pressing plate 45 .

[0029] When the user adds slurry to the inside of the storage barrel 3, the electric threaded rod 41 is started, and the pressing plate 45 moves to the top of the storage barrel 3 with the cooperation of the electric threaded rod 41 and the moving rod 43. The position of the feed port 32 ensures that the slurry entering the storage barrel 3 from the feed port 32 will not contact the top of the pressing plate 45, thereby preventing the slurry from accumulating on the top of the pressing plate 45 for a long time, which will affect the quality of the slurry and the cleaning effect of the storage barrel 3 by the staff.

[0030] Specifically, the width of the top opening of the feeding trough 54 is greater than the distance between the bottom opening of the feeding trough 54 and the side wall on the same side of the top opening of the flushing trough 53 .

[0031] The width of the top opening of the feed trough 54 ensures that when the user adjusts the flow direction of the slurry in the feed trough 54 by controlling the rotation of the rotating drum 52, the top opening of the feed trough 54 always remains connected with the upper half of the feed pipe 51. The relationship between the distance between the top opening of the feed trough 54 and the bottom opening of the feed trough 54 and the top opening of the flushing trough 53 ensures that when the bottom opening of the feed trough 54 is connected with the lower half of the feed pipe 51 or the flushing trough 53, the feed trough 54 is always in a state of connection with the upper half of the feed pipe 51, thereby ensuring the working effect of the rotating drum 52 and the feed trough 54.

[0032] Specifically, the shape of the side wall of the feeding trough 54 located at the bottom is in a downwardly inclined state.

[0033] The shape of the side wall of the feed trough 54 at the bottom ensures that the slurry will not accumulate on the side wall of the feed trough 54 at the bottom during the flow inside the feed trough 54, thereby ensuring the working effect of the feed trough 54.

[0034] Specifically, a mounting ring 11 is provided on the top of the mixing barrel 1 , a groove matching with the mounting ring 11 is provided on the bottom of the barrel cover 12 , and a rubber pad is provided on the side wall of the mounting ring 11 .

[0035] The mounting ring 11 plays a guiding and fixing role. The cooperation between the mounting ring 11 and the bottom groove of the barrel cover 12 ensures the stability of the barrel cover 12 after being installed on the mixing barrel 1. The rubber pad arranged on the mounting ring 11 plays a buffering role, reducing the damage to the mounting ring 11 and the barrel cover 12 during the use of the device. The rubber pad arranged on the mounting ring 11 also increases the friction between the barrel cover 12 and the mounting ring 11, further improving the stability of the barrel cover 12 during the use of the device.

[0036] The working principle and use process of the utility model are as follows: slurry is fed into the storage barrel 3 through the feed port 32. When the slurry is prepared, the electric threaded rod 41 is started to open the electric valve 2 33. The moving rod 43 moves along the electric threaded rod 41 under the action of the thread. The moving rod 43 will move downward with the pressing plate 45 during the movement. The slurry in the storage barrel 3 enters the feeding pipe 51 through the electric valve 2 33 under the pressure of the pressing plate 45. After the moving rod 43 moves to a suitable position, the electric valve 2 33 is closed. The electric threaded rod 41 is used to complete the quantitative feeding of the slurry. The slurry entering the feeding pipe 51 will enter the mixing barrel 1 through the feeding trough 54, and the electric stirring shaft 2 is started to stir and mix the slurry in the mixing barrel 1. After the slurry mixing is completed, the mixed slurry is discharged from the mixing barrel 1 through the bottom discharge port of the mixing barrel 1. When cleaning all the storage barrels 3 and the mixing barrel 1, the electric valve 34 is controlled to open, and cleaning water is sent into the interior of the storage barrel 3 through a connecting valve 56 set on a connecting pipe 31. After the mixing barrel 1 is filled with cleaning water, the electric valve 2 33 is opened, and the cleaning water enters the mixing barrel 1 through the electric valve 2 33 and the material delivery pipe 51. As the water continues to enter the storage barrel 3, the storage barrel 3 is cleaned. After the mixing barrel 1 is filled with water, the electric stirring shaft 2 is started, the bottom opening of the mixing barrel 1 is opened, and water is continuously delivered to the connecting valve 56 provided on the connecting pipe 31 until the mixing barrel 1 is cleaned. When cleaning the storage barrel 3 alone, the opening and closing of the electric valve 1 34 are adjusted to make the storage barrel 3 that needs to be cleaned as much as possible. The cleaning water is fed into the material storage barrel 3 to be cleaned through the connecting valve 56 arranged on the connecting pipe 31, and the rotating drum 52 coordinated with the material storage barrel 3 to be cleaned is controlled to rotate so that the feeding trough 54 is connected with the flushing trough 53, and the connecting valve 56 arranged on the electric valve 2 33 and the mixing liquid ring 55 is opened. The water in the material storage barrel 3 enters the mixing liquid ring 55 through the cooperation of the flushing trough 53 and the feeding trough 54, and then the water is discharged from the mixing liquid ring 55 through the connecting valve 56 arranged on the mixing liquid ring 55, thereby completing the cleaning of the material storage barrel 3.
