Description

Technical Field

[0001] This invention pertains to feeding equipment, and more specifically to the field of calcium hypochlorite preparation, and more specifically to a quantitative feeding device for calcium hypochlorite preparation. Background Technology

[0002] Calcium hypochlorite is a common chemical substance, a white crystalline solid that is hygroscopic and soluble in water. It plays an important role in water treatment. Because it is soluble in water and releases hypochlorite ions, it is widely used as a disinfectant. Calcium hypochlorite can kill bacteria, viruses, and other microorganisms in water, thus ensuring water safety and cleanliness. In addition, calcium hypochlorite can also be used to bleach paper, fabrics, and other items, with excellent bleaching effects. In the preparation of calcium hypochlorite, feeding equipment is required for automatic batching.

[0003] Existing feeding equipment typically controls the feeding amount by controlling the opening and closing of valves. Since the raw material for calcium chlorate preparation is in powder form, this feeding method is not precise enough in controlling the amount, resulting in a large error. Furthermore, blockages are prone to occur during the feeding process, which affects the feeding speed and increases the error. To address these issues, the existing equipment needs to be improved.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1 to 10 This invention provides a technical solution: a quantitative feeding device for preparing calcium hypochlorite, comprising a base 1, two bearing plates 2 fixed to one side of the upper surface of the base 1, a storage box 3 fixed to the top of the two bearing plates 2, a feed inlet 4 opened at the top of the storage box 3, a discharge outlet 5 opened at the bottom of the storage box 3, a quantitative feeding mechanism 6 fixed to one side of the storage box 3, the quantitative feeding mechanism 6 including a support plate 601, the bottom of the support plate 601 being connected to a moving frame 603 via an electric telescopic column 602, and a support ring 60 fixed to the inner side of the moving frame 603. 4. A first hydraulic cylinder 605 is rotatably connected to the inner side of the support ring 604. Both sides of the first hydraulic cylinder 605 are connected to the first feeding pipe 611 through the connecting rod 610. One of the first feeding pipes 611 passes through the feeding port 5. A first piston 612 is slidably connected inside the first hydraulic cylinder 605. The first piston 612 passes through the bottom of the first hydraulic cylinder 605 and is connected to the moving plate 614. Second feeding pipes 615 are symmetrically fixed on both sides of the moving plate 614. The second feeding pipes 615 are slidably connected to the inner side of the first feeding pipe 611.

[0020] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, two first limiting rings 606 are fixed to the outer side of the first cylinder 605, and a support ring 604 is located between the two first limiting rings 606. A gear ring 607 is fixed to the outer side of the first cylinder 605. A first motor 608 is fixed inside the top of the moving frame 603, and the bottom of the first motor 608 is connected to the first spur gear 609. The gear ring 607 is meshed with one side of the first spur gear 609. The first spur gear 609 can rotate under the action of the first motor 608. Since the first spur gear 609 and the gear ring 607 are meshed together, the first cylinder 605 will rotate with the rotation of the first spur gear 609. The support ring 604 and the two first limiting rings 606 are used together to support and limit the first cylinder 605.

[0021] In this embodiment, as Figure 1 , Figure 4 and Figure 7As shown, the front side of the first hydraulic cylinder 605 is threaded with a fastener 613. The first piston 612 is fixed to the first hydraulic cylinder 605 by the fastener 613. The second feeding pipe 615 and the first feeding pipe 611 form a telescopic structure, and the second feeding pipe 615 is marked with a scale. After loosening the fastener 613, the first piston 612, the moving plate 614 and the two second feeding pipes 615 can be moved up and down manually. By adjusting the depth of the second feeding pipe 615 into the first feeding pipe 611, the overall capacity of the first feeding pipe 611 and the second feeding pipe 615 can be adjusted. The amount can be precisely controlled by observing the scale. After the adjustment operation is completed, the fastener 613 can be tightened to lock the first piston 612.

[0022] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, a sleeve plate 616 is fixed to the bottom of the movable plate 614, and a first sealing plate 617 passes through the sleeve plate 616. A slider 618 is fixed to the bottom of the first sealing plate 617. A slide rail 619 is provided at the bottom of the movable plate 614. The slider 618 is slidably connected in the slide rail 619. The sleeve plate 616 supports the first sealing plate 617. When the first sealing plate 617 moves left and right, the slider 618 slides in the slide rail 619, which facilitates the limiting function.

[0023] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, a second hydraulic cylinder 622 is fixed to the other side of the upper surface of the base 1. A first connecting pipe 620 is fixed to the top of the first hydraulic cylinder 605. A second connecting pipe 621 is fixed to one side of the second hydraulic cylinder 622, and the first end of the second connecting pipe 621 is rotatably connected to the top of the first connecting pipe 620. A second piston 623 is slidably connected inside the second hydraulic cylinder 622, and the second piston 623 passes through the top of the second hydraulic cylinder 622 and is connected to a third hydraulic cylinder 624. A third piston 62 is slidably connected inside the third hydraulic cylinder 624. 5. The third piston 625 passes through one end of the third cylinder 624 and is connected to the pull block 626. The first connecting pipe 620 and the second connecting pipe 621 serve to connect the first cylinder 605 and the second cylinder 622. During the up-and-down movement of the first piston 612, the moving plate 614 and the sleeve plate 616 move up and down accordingly. At the same time, the second piston 623 moves up and down, thereby driving the third cylinder 624, the third piston 625 and the pull block 626 to move up and down as a whole, ensuring that the pull block 626 moves synchronously with the slider 618.

[0024] In this embodiment, as Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 9 As shown, a support box 627 is fixed between the two support plates 2, and a second motor 628 is fixed inside the support box 627. The top of the second motor 628 is connected to the first rotating shaft 629, and an extrusion wheel 630 is fixed to the outside of the first rotating shaft 629. An incomplete gear 631 is fixed to the top of the first rotating shaft 629. The first rotating shaft 629 can rotate under the action of the second motor 628, thereby driving the extrusion wheel 630 to rotate, which facilitates the extrusion of the corresponding components.

[0025] In this embodiment, as Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 9 As shown, a fourth hydraulic cylinder 632 is fixed to one side of the support box 627, and the fourth hydraulic cylinder 632 is connected to the third hydraulic cylinder 624 through a third connecting pipe 636. A fourth piston 634 is slidably connected inside the fourth hydraulic cylinder 632, and the fourth piston 634 is connected to one inner wall of the fourth piston 634 through a spring 633. A movable rod 635 is fixed to one side of the fourth piston 634, and the movable rod 635 passes through one side of the fourth hydraulic cylinder 632 and abuts against the extrusion roller 630. The third connecting pipe 636 serves to connect the third hydraulic cylinder 624 and the fourth hydraulic cylinder 632. When the extrusion roller 630 rotates and extrudes the movable rod 635, the movable rod 635 and the fourth piston 634 move to the right, and the third piston 625 moves to the left. When the extrusion roller 630 releases the extrusion on the movable rod 635, the movable rod 635 and the fourth piston 634 automatically spring away to the left under the action of the spring 633, and the third piston 625 moves to the right.

[0026] In this embodiment, as Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, a second rotating shaft 638 is rotatably connected to the bottom of the storage box 3. A rubber clip 639 is fixed to one side of the second rotating shaft 638 and is engaged with the storage box 3. A second sealing plate 640 is fixed to the top of the second rotating shaft 638 and a second spur gear 637 is fixed to the bottom of the second rotating shaft 638. When the incomplete gear 631 rotates and meshes with the second spur gear 637, the second spur gear 637 will rotate with the rotation of the incomplete gear 631, thereby driving the second sealing plate 640 to rotate, which facilitates sealing or opening the corresponding first discharge pipe 611. When the incomplete gear 631 is not meshed with the second spur gear 637, the rubber clip 639 is locked on the storage box 3, which facilitates locking and prevents the second rotating shaft 638 from rotating on its own.

[0027] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a third motor 641 is fixed inside the support plate 601, and the top of the third motor 641 is connected to the lead screw 642. A belt drive assembly 643 is fixed to the top of the lead screw 642. A fixed plate 644 is fixed to one side of the storage box 3. The belt drive assembly 643 is rotatably connected to the bottom of the fixed plate 644. A first sleeve 645 is threaded to the outer side of the lead screw 642, and movable plates 646 are symmetrically fixed on both sides of the first sleeve 645. A support column 647 is fixed to the outer end of one of the movable plates 646. A push plate 648 is fixed to the bottom of the support column 647. The lead screw 642 can rotate under the action of the third motor 641. The first sleeve 645, two movable plates 646, support column 647 and push plate 648 move downward as a whole. The push plate 648 extends into the corresponding first discharge pipe 611 and second discharge pipe 615 to facilitate fast material discharge. An annular scraper ring is fixed to the outside of the push plate 648 to scrape the material and prevent the material from adhering to the inner wall of the first discharge pipe 611 and second discharge pipe 615.

[0028] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the output end of the belt drive assembly 643 is connected to the square column 649, and a second sleeve 650 is slidably connected to the outer side of the square column 649. The second sleeve 650 passes through another movable plate 646 and the top of the storage box 3, and two second limiting rings 651 are fixed to the outer side of the second sleeve 650. The other movable plate 646 is located between the two second limiting rings 651. A stirring rod 652 is fixed to the bottom of the second sleeve 650. When the screw 642 rotates, the storage box 3 limits the second sleeve 650, so that the first sleeve... 645, the two movable plates 646, the second sleeve 650, and the stirring rod 652 can move downwards as a whole. At the same time, the screw 642 rotates, driving the belt drive assembly 643 to rotate, thereby driving the square column 649 to rotate. The second sleeve 650 and the stirring rod 652 rotate. The stirring rod 652 moves downwards while rotating and extends into the corresponding first discharge pipe 611 and second discharge pipe 615, which facilitates the unblocking function and allows the material in the storage box 3 to enter the first discharge pipe 611 and the second discharge pipe 615 better.

[0029] The method of use and advantages of this invention: The quantitative feeding device for preparing calcium hypochlorite operates as follows: like Figures 1 to 10As shown: After connecting to an external power source and loosening the fastener 613, manually move the first piston 612, the moving plate 614, and the two second feeding pipes 615 up and down to adjust the capacity of the combination of the first feeding pipe 611 and the second feeding pipe 615, thereby controlling the feeding amount. At the same time, the second piston 623, the third cylinder 624, the third piston 625, and the pull block 626 move downwards synchronously. The pull block 626 and the slider 618 remain relatively stationary. After completing the adjustment operation, tighten the fastener 613 to lock the first piston 612, and pass the material through the feed inlet 4 into the storage box 3. Then, the incomplete gear 631 rotates, the first rotating shaft 629 and the extrusion wheel 630 rotate, and the extrusion wheel 630 extrudes the movable rod 635. Pistons 635 and 634 move to the right, while pistons 625 and 626 move to the left, pulling slider 618 and first sealing plate 617 to the left. This seals the left-side second discharge pipe 615 and opens the right-side second discharge pipe 615. Subsequently, incomplete gear 631 meshes with second spur gear 637, which rotates along with 631, driving second shaft 638 and second sealing plate 640 to rotate. The second sealing plate 640 rotates 180 degrees and moves away from above the first discharge pipe 611, opening it. Material enters the corresponding first discharge pipe 611 and second discharge pipe 615, thus channeling material from storage bin 3 to... During the process within the first discharge pipe 611 and the second discharge pipe 615, the rotation of the lead screw 642 drives the first sleeve 645, two movable plates 646, support column 647, push plate 648, second sleeve 650, and stirring rod 652 to move downwards as a whole. Simultaneously, the belt drive assembly 643 rotates, driving the square column 649 to rotate, and the second sleeve 650 and stirring rod 652 to rotate. The stirring rod 652 rotates while moving downwards and extending into the first discharge pipe 611 and the second discharge pipe 615 on the left, thus clearing blockages and allowing the material in the storage box 3 to flow more smoothly and quickly into the first discharge pipe 611 and the second discharge pipe 615. Afterwards, the incomplete gear 631 continues to rotate, driving the second spur gear 637 to rotate. The second sealing plate 640 continues to rotate 180 degrees to seal the first discharge pipe 611 on the left. At the same time, the pull block 626 moves to the right and resets. Then, the first sprocket 609 rotates, driving the first cylinder 605, the two connecting rods 610, the two first discharge pipes 611, the two second discharge pipes 615, the first piston 612, the moving plate 614, the sleeve plate 616, and the first sealing plate 617 to rotate 180 degrees as a whole, thereby swapping the positions of the two first discharge pipes 611. The above operation is then repeated. While the stirring rod 652 clears one of the first discharge pipes 611 and the second discharge pipe 615, the push plate 648 can push and scrape the material in the other first discharge pipe 611 and the second discharge pipe 615, facilitating rapid material discharge.This prevents material from adhering to the inner walls of the first discharge pipe 611 and the second discharge pipe 615, thus avoiding incomplete discharge.

[0030] In summary, this quantitative feeding device for calcium hypochlorite preparation achieves the goals of quantitative feeding, automatic unblocking to avoid material blockage, and automatic material pushing and scraping, thus meeting people's usage needs.
