Description

Technical Field

[0001] The utility model relates to the technical field of chemical production, and particularly relates to a chemical feeding device. Background Art

[0002] Chemical production refers to the industrial production activities that use principles and methods of chemistry, physics, engineering, etc., and through a series of technological processes and operations, convert various raw materials into chemical products with specific chemical structures and properties.

[0003] In the process of chemical production, the feeding link is crucial. There are generally some problems with existing chemical feeding devices. It is difficult to ensure the feeding accuracy of traditional feeding devices, which easily leads to fluctuations in product quality. There is a need to develop a chemical feeding device to meet the feeding requirements of chemical raw materials.

[0004] Chinese Patent Publication No.: CN212263196U discloses "A Chemical Feeding Device". The technical problem to be solved by this utility model is that the powdered materials absorb water and agglomerate, making it inconvenient to feed. To solve the above technical problem, this utility model provides a chemical feeding device, including a mixing chamber. A feeding cylinder is movably penetrated through the top of the mixing chamber. Filter plates are fixedly connected to the middle parts of both sides of the inner wall of the feeding cylinder and the bottom parts of both sides of the inner wall. A connecting ring is sleeved on the outer side of the middle part of the feeding cylinder. Reset structures are fixedly connected to both sides of the connecting ring. A top rod is fixedly connected to the left side of the connecting ring. The top of the mixing chamber is connected with a cover plate through a hinge connector. A reset spring is fixedly connected between the bottom of the cover plate and the left side inner wall of the mixing chamber. A buckle is hinged to the right side of the mixing chamber. A driving motor is fixedly connected to the left side of the mixing chamber through a connecting rod. A stirring shaft cylinder is movably penetrated through the mixing chamber. The output shaft of the driving motor is sleeved with a lower gear.

[0005] In the above prior art, the device is provided with a cam. The cam will cause the feeding cylinder to move upward and vibrate, and the filter plate is used to break up the agglomerated powdered materials, accelerating the dispersion of the agglomerated powdered materials for feeding, solving the problem that the powdered materials absorb water and agglomerate, making it inconvenient to feed. The device is provided with a closable cover plate at the top of the feeding cylinder to prevent the powdered materials from turning into dust and escaping from the feeding place during the vibration of the filter plate, causing environmental pollution. When the device opens the switch valve for feeding and completes the feeding, the wire take-up wheel makes the pull rope open the cover plate, simplifying the working steps and facilitating the next feeding. However, in the process of using the existing device, it does not have the function of adjusting the height of the feeding port. When using it for feeding equipment or reaction vessels with different heights, it is difficult for the fixed-height feeding port to be accurately docked with them, which increases the complexity and time cost of operation to a certain extent.

By starting the first motor 301, the first motor 301 drives the forward and reverse lead screw 302 to rotate. The rotation of the forward and reverse lead screw 302 drives the symmetrically arranged moving blocks 303 to move relatively. The relative movement of the symmetrically arranged moving blocks 303 drives the symmetrically arranged hinge blocks 304 to move relatively, thereby driving the angles of the symmetrically arranged connecting rods 305 to change. The change in the angles of the symmetrically arranged connecting rods 305 drives the lifting plate 306 to move. The movement of the lifting plate 306 drives the lifting rod 307 to move. The movement of the lifting rod 307 drives the mounting block 308 to move, thereby driving the feeding bin 4 to move up and down to adjust the position. By means of the flap component 9 provided, the opening and closing of the discharge port 8 are controlled to achieve accurate control of the discharging operation. By starting the third motor 903, the third motor 903 drives the first gear 904 to rotate. The rotation of the first gear 904 drives the second gear 905 to rotate. The rotation of the second gear 905 drives the rotating rod 906 to rotate. The rotation of the rotating rod 906 drives the flap 907 to flip. The flipping of the flap 907 drives the pressure ring 908 to move away from the discharge port 8, realizing the control of the opening and closing of the discharge port 8.

One end of the connecting rod 305 is hinged to the moving block 303 through the hinge block 304, and the other end of the connecting rod 305 is hinged to the lifting plate 306 through the hinge block 304.

[0032] Through the above technical solution, the rotation of the positive and negative lead screws 302 drives the symmetrically arranged moving blocks 303 to move relative to each other. The relative movement of the symmetrically arranged moving blocks 303 drives the symmetrically arranged hinge blocks 304 to move relative to each other, thereby driving the angles of the symmetrically arranged connecting rods 305 to change. The change in the angles of the symmetrically arranged connecting rods 305 drives the lifting plate 306 to move, converting the rotational motion into a lifting motion.

[0034] Through the above technical solution, by using the sliding of the lifting plate 306 in the base 1, the stability of the movement of the lifting plate 306 is ensured. The movement of the lifting plate 306 drives the movement of the lifting rod 307, and the movement of the lifting rod 307 drives the movement of the mounting block 308, thereby driving the feeding bin 4 to move up and down to adjust to the position. The feeding bin 4 is conveniently detachable and installable at the upper end of the mounting block 308.

The third motor 903 is externally connected to a power supply and a controller, which is used to ensure the independent operation of each device. The third motor 903 is used to drive the first gear 904 to rotate, and the rotation of the first gear 904 drives the second gear 905 to rotate.

[0037] Specifically, the rotating rod 906 passes through the fixing block 901 and the placing bin 902 and extends to the outside thereof. One end of the rotating rod 906 is fixedly connected to the flap 907, and the pressing ring 908 is of an annular structure.

[0038] Through the above technical solution, the rotation of the second gear 905 drives the rotation of the rotating rod 906. The rotation of the rotating rod 906 drives the flipping of the flap 907. The flipping of the flap 907 drives the pressing ring 908 to manage the discharge port 8, realizing the opening and closing control of the discharge port 8. The annular pressing ring 908 improves the sealing performance of the discharge port 8.

[0039] During use, when it is necessary to adjust the discharge port 8 to an appropriate height, start the first motor 301. The first motor 301 drives the forward and reverse screw rod 302 to rotate. The rotation of the forward and reverse screw rod 302 drives the symmetrically arranged moving blocks 303 to move relative to each other. The relative movement of the symmetrically arranged moving blocks 303 drives the symmetrically arranged hinge blocks 304 to move relative to each other. The relative movement of the symmetrically arranged hinge blocks 304 drives the symmetrically arranged connecting rods 305 to change their angles. The change in the angles of the symmetrically arranged connecting rods 305 drives the lifting plate 306 to move. The movement of the lifting plate 306 drives the lifting rod 307 to move. The movement of the lifting rod 307 drives the mounting block 308 to move. The movement of the mounting block 308 drives the feeding bin 4 to move up and down to adjust to an appropriate height. When it is necessary to control the opening and closing of the discharge port 8, start the third motor 903 to drive the first gear 904 to rotate. The rotation of the first gear 904 drives the second gear 905 to rotate. The rotation of the second gear 905 drives the rotating rod 906 to rotate.
