Description

Technical Field

[0001] This utility model relates to the technical field of polyaluminum chloride production equipment, specifically to a polyaluminum chloride drum drying device. Background Technology

[0002] Polyaluminum chloride, commonly known as water purification agent, or simply polyaluminum, is a cationic inorganic polymeric flocculant with multiple hydroxyl groups and polynuclear complexes. The solid product appears as a yellow or white solid powder, is easily soluble in water, and has strong bridging adsorption properties. During hydrolysis, it undergoes physicochemical changes such as electrochemical processes, coagulation, adsorption, and precipitation, ultimately generating Al2(OH)3(OH)3, thereby achieving the purification purpose. When drying polyaluminum chloride, a polyaluminum chloride drum drying device is required.

[0003] Existing drying devices cannot conveniently and effectively discharge polyaluminum chloride after drying. During the discharge process, some polyaluminum chloride accumulates in the dead corners of the drum. If the polyaluminum chloride in the dead corners cannot be scraped off, it will result in a large amount of waste of polyaluminum chloride. At the same time, it is inconvenient for staff to clean the inside of the drum, which reduces the overall practicality of the device.

[0004] Compared with Chinese Patent Publication No. CN209246572U, this utility model discloses a device for drying polyaluminum chloride, including a base. Two support plates are symmetrically fixedly connected to the top of the base, and a roller is disposed between the two support plates. A rotating rod is rotatably connected to the side wall of the roller via a first bearing. One support plate has a through hole matching the rotating rod on its side wall, and the rotating rod extends into the through hole. Two first sliders are symmetrically fixedly connected to the side wall of the rotating rod. Two first grooves matching the first sliders are formed on the side wall of the through hole. The side walls of the two first sliders are fixedly connected to the side walls of the first grooves via springs. A movable rod is fixedly connected to the side wall of the roller opposite to the rotating rod, and a cylinder is sleeved on the movable rod. Two second sliders are symmetrically fixedly connected to the side wall of the movable rod. This utility model can dry polyaluminum chloride and simultaneously allow the polyaluminum chloride to be turned back and forth, improving the drying effect and efficiency.

[0005] The above solution can effectively dry polyaluminum chloride, but after drying the polyaluminum chloride, it still cannot effectively scrape off the polyaluminum chloride in the dead corners inside the drum, thus failing to solve the problem mentioned in the background art.

[0006] Therefore, those skilled in the art have provided a polyaluminum chloride drum drying apparatus to solve the problems mentioned in the background art. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1 - Figure 5 As shown, this embodiment provides a polyaluminum chloride drum drying device, including a support frame 1, and further comprising:

[0029] Support base 2 is fixedly connected to the outside of support frame 1;

[0030] The drying drum 5 is located above the support base 2, and the outside of the drying drum 5 has a movable hole for the sealing cover 9 to move.

[0031] The feeding assembly is located outside the drying drum 5;

[0032] The fixing frame 6 is fixedly connected to the upper surface of the support frame 1;

[0033] The drying component is located on the rear end surface of the support frame 1.

[0034] The working principle described above is as follows: When polyaluminum chloride needs to be dried, simply open the sealing cover 9 first, add the polyaluminum chloride into the drying drum 5, and then close the sealing cover 9. At this time, the first motor 11 starts running, driving the drying drum 5 to rotate synchronously. During the rotation of the drying drum 5, the drying component also starts running synchronously. At this time, the drying component can effectively and evenly dry the polyaluminum chloride inside the drying drum 5. After the polyaluminum chloride is dried, open the sealing cover 9 again. At this time, the pushing component starts running. The pushing component can effectively push the polyaluminum chloride inside the drying drum 5 to the discharge port of the drying drum 5, thereby facilitating the discharge of the dried polyaluminum chloride by the staff, avoiding the accumulation of polyaluminum chloride in the dead corners of the drying drum 5, reducing the waste of polyaluminum chloride, and effectively improving the overall practicality of the device.

[0035] To enable the drying drum 5 to rotate, thus achieving more comprehensive and uniform drying of polyaluminum chloride, rotating rods 13 are fixedly connected to both sides of the outer wall of the drying drum 5. The other ends of the two rotating rods 13 are rotatably connected to the inner wall of the support frame 1. A first motor 11 is fixedly connected to the outside of the support frame 1. The output shaft of the first motor 11 is fixedly connected to the other end of one of the rotating rods 13 via a coupling. When the polyaluminum chloride is completely added into the drying drum 5, the first motor 11 starts running, driving the rotating rods 13 to rotate synchronously. The rotating rods 13 then drive the drying drum 5 to rotate synchronously. During the rotation of the drying drum 5, the polyaluminum chloride will tumble repeatedly inside the drying drum 5. With the cooperation of the drying components, the polyaluminum chloride can be dried more comprehensively and evenly, effectively improving the drying effect and efficiency of polyaluminum chloride.

[0036] Considering that some polyaluminum chloride will accumulate in the dead corners inside the drying drum 5 after drying, the feeding assembly includes multiple fixed plates 15 fixedly connected to the outside of the drying drum 5. An adjusting plate 16 is fixedly connected to the outside of every four fixed plates 15. A bidirectional threaded rod 17 is rotatably connected to the inner wall of each adjusting plate 16. A U-shaped frame 22 is fixedly connected to the outside of every two adjusting plates 16. The other end of each bidirectional threaded rod 17 is rotatably connected to the outside of the U-shaped frame 22. A second motor 23 is fixedly connected to the outside of each U-shaped frame 22. The output shaft of the second motor 23 is fixedly connected to the other end of one of the bidirectional threaded rods 17 via a coupling. Each pair of bidirectional threaded rods 17 is connected by a synchronous belt 24 and a pulley. Threaded blocks 18 are symmetrically arranged on the outside of the bidirectional threaded rods 17. A guide groove for the movement of the threaded blocks 18 is opened on the outside of the adjusting plate 16. A hinge block 20 is hinged inside each pair of threaded blocks 18 via a connecting rod 19. Moving rods 21 are fixedly connected to the outside of each set of hinge blocks 20. A push plate 12 is fixedly connected to the other end of each pair of moving rods 21. The drying drum 5... Guide grooves for the movable rod 21 are provided on both sides of the wall. After the polyaluminum chloride is dried, the sealing cover 9 is opened. At this time, the two second motors 23 will start running synchronously. The second motors 23 will drive the bidirectional threaded rods 17 to rotate synchronously. Since each pair of bidirectional threaded rods 17 is connected by a synchronous belt 24 and a pulley, multiple bidirectional threaded rods 17 will rotate synchronously. The threaded blocks 18 will move synchronously outside the bidirectional threaded rods 17. Furthermore, since each pair of threaded blocks 18 is connected to the hinge block 20 by a connecting rod 19... Since it is hinged, the threaded block 18 will drive the hinged block 20 to move synchronously through the connecting rod 19. The hinged block 20 will then drive the moving rod 21 to move synchronously, and the moving rod 21 will then drive the push plate 12 to move synchronously. At this time, the push plate 12 can push the polyaluminum chloride inside the drying drum 5, which makes it easier for the staff to discharge the polyaluminum chloride inside the drying drum 5 and avoid the accumulation of polyaluminum chloride in the dead corners inside the drying drum 5, effectively improving the overall practicality of the device (the precision of multiple bidirectional threaded rods 17 is consistent).

[0037] To effectively dry the polyaluminum chloride inside the drying drum 5, the drying assembly includes a hot air blower 14 fixedly connected to the rear end surface of the support frame 1. Multiple mounting holes for installing suction fans 7 are provided through the upper surface of the support frame 6. Multiple air inlets 8 are fixedly connected to the upper surface of the support frame 6. The outlet of the hot air blower 14 is connected to the interior of the multiple air inlets 8 via pipes. When the polyaluminum chloride needs to be dried, the hot air blower 14 starts operating, transmitting hot air through pipes to the interior of the air inlets 8. Simultaneously, the suction fans 7 also start operating, drawing the hot air to the outside of the drying drum 5, thus effectively drying the polyaluminum chloride inside the drying drum 5.

[0038] To facilitate the collection and processing of dried polyaluminum chloride by staff, a positioning frame 3 is fixedly connected to the upper surface of the support base 2. The positioning frame 3 has a collection frame 4 inside, which facilitates the collection and processing of polyaluminum chloride by staff.

[0039] In addition, in order to effectively improve the overall stability of the device during operation, an anti-slip pad 10 is attached to the bottom of the support base 2. The bottom of the anti-slip pad 10 has herringbone anti-slip grooves at equal intervals. The anti-slip pad 10 and the herringbone anti-slip grooves can effectively increase the friction between the support base 2 and the ground, thereby preventing the device from shifting during operation and effectively improving the overall stability of the device.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
