DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 to Figure 4 In the embodiment of the utility model, a rapid dehydration device for environmental protection engineering includes a dehydration box 1 and a feed hopper 8 connected and installed on one side of the top of the dehydration box 1 for sewage discharge. The interior of the dehydration box 1 is provided with a dehydration mechanism for rapid dehydration. The dehydration mechanism includes a dehydration cylinder 31, a toothed disc 32, a gear 33 and a motor 34. The interior of the dehydration box 1 is provided with a dehydration cylinder 31. The side wall of the dehydration cylinder 31 is rotatably connected to the inner wall of the dehydration box 1 through a supporting assembly. The bottom end of the dehydration cylinder 31 is connected to the inner wall of the dehydration box 1. A discharge pipe 35 is installed through the bottom of the dehydration box 1, and a solenoid valve 10 is installed on the surface of the discharge pipe 35. The outer wall of the discharge pipe 35 is sealed and rotatably connected to the bottom inner wall of the dehydration box 1. A toothed disc 32 is welded to the top of the side wall of the dehydration cylinder 31, and a gear 33 is arranged side by side on one side of the toothed disc 32. The gear 33 is meshingly connected with the toothed disc 32. A motor 34 is installed on the top side of the dehydration box 1 by bolts, and the output shaft of the motor 34 passes through the dehydration box 1 and is fixedly connected to the top surface of the gear 33.

[0023] The support assembly includes a support plate 41 welded to the top and bottom ends of the side wall of the dehydration cylinder 31. A circular groove 42 matching the support plate 41 is provided on the inner wall of the dehydration box 1. The end of the support plate 41 away from the dehydration cylinder 31 extends into the interior of the circular groove 42 and is rotatably connected to the circular groove 42. The support plate 41 and the circular groove 42 cooperate to provide stable support for the dehydration cylinder 31.

[0024] During use, after the sewage enters the dewatering cylinder 31 inside the dewatering box 1 through the feed hopper 8, the motor 34 is started. When the output shaft of the motor 34 rotates, it drives the gear 33 to rotate synchronously, so that the toothed disc 32 meshing with it rotates accordingly, and then the rotation of the toothed disc 32 drives the dewatering cylinder 31 to rotate synchronously. At the same time, the support plate 41 also rotates inside the circular groove 42. When the dewatering cylinder 31 rotates, the sewage inside it rotates rapidly and the dewatering operation is performed. At this time, the sludge and debris remain in the dewatering cylinder 31, and the sewage enters the dewatering box 1 through the filter holes on the side wall of the dewatering cylinder 31. When the dewatering operation is completed, the solenoid valve 10 is controlled to open, and the sludge and debris accumulated in the dewatering cylinder 31 will be discharged to the external waste collection box through the discharge pipe 35 for centralized collection and treatment.

[0025] The interior of the dehydration cylinder 31 is provided with a scraping mechanism for scraping and preventing blockage during dehydration. The scraping mechanism includes a fixed rod 51, a connecting rod 52, a movable rod 53, a scraper 54 and a spring 55. A fixed rod 51 is provided in the middle of the interior of the dehydration cylinder 31. The inner wall of the dehydration box 1 is fixed with a horizontal plate 11 located above the dehydration cylinder 31 by screws. The top of the fixed rod 51 extends to the outside of the top of the dehydration cylinder 31 and is welded to the bottom surface of the horizontal plate 11. The top and bottom of the side walls of the fixed rod 51 are symmetrically welded with connecting rods 52. The interior of the connecting rod 52 is slidably connected with a movable rod 53. One end of the movable rod 53 penetrates the connecting rod 52 and is welded to the side wall of the scraper 54. The side of the scraper 54 away from the movable rod 53 contacts the inner wall of the dehydration cylinder 31. The surface of the movable rod 53 is sleeved with a spring 55 located between the connecting rod 52 and the scraper 54. One end of the spring 55 is fixedly connected to the end of the connecting rod 52, and the other end of the spring 55 is fixedly connected to the side wall of the scraper 54.

[0026] During use, when the dewatering cylinder 31 rotates for dehydration, the scraper 54 can continuously scrape off the sludge and debris attached to its inner wall, thereby preventing the sludge and debris from clogging the filter holes on the side walls of the dewatering cylinder 31, thereby accelerating the dehydration efficiency of the rapid dehydration equipment used in the environmental protection project. When the scraper 54 scrapes the inner wall of the dewatering cylinder 31, the extrusion force generated by the scraper 54 causes the movable rod 53 to slide toward the inside of the connecting rod 52, and at the same time the spring 55 is compressed and deformed, thereby preventing the scraper 54 from being damaged by long-term rigid contact with the inner wall of the dewatering cylinder 31.

[0027] One side of the dehydration box 1 is connected to the purification box 2 through a pumping mechanism, and the pumping mechanism includes a first water pump 61, a pumping pipe 62, a second water pump 63 and a water supply pipe 64. A first water pump 61 is provided on one side of the dehydration box 1, and both ends of the first water pump 61 are connected and installed with pumping pipes 62. The pumping pipe 62 connected to the water outlet end of the first water pump 61 extends to the inside of the top surface of the purification box 2, and the pumping pipe 62 connected to the water inlet end of the first water pump 61 extends to the inside of the bottom surface of the dehydration box 1. A second water pump 63 is installed on the side of the purification box 2 away from the first water pump 61, and both ends of the second water pump 63 are connected and installed with water supply pipes 64. The water supply pipe 64 connected to the water outlet end of the second water pump 63 extends to the inside of the top surface of the dehydration box 1, and the water supply pipe 64 connected to the water inlet end of the second water pump 63 extends to the inside of the bottom end of one side of the purification box 2.

[0028] A purification mechanism for purifying the sewage discharged after dehydration is provided inside the purification box 2, and the purification mechanism includes a quartz sand filter plate 71, an impurity removal filter plate 72 and an activated carbon filter plate 73. A plurality of placement grooves 12 are provided on the inner wall of the purification box 2 from left to right, and quartz sand filter plates 71, impurity removal filter plates 72 and activated carbon filter plates 73 are slidingly placed inside the placement grooves 12, respectively, and the quartz sand filter plates 71, impurity removal filter plates 72 and activated carbon filter plates 73 are arranged in sequence from left to right. A drain pipe 9 is installed at the bottom end of the side of the purification box 2 away from the dehydration box 1 for discharging the sewage after purification.

[0029] When in use, start the first water pump 61 to pump the sewage separated from the dehydration box 1 into the purification box 2 through the pumping pipe 62, and then pass through the quartz sand filter plate 71, the impurity removal filter plate 72 and the activated carbon filter plate 73 for multiple filtration and purification in sequence. The quartz sand filter plate 71 and the impurity removal filter plate 72 can filter out large particles of impurities in the sewage, and the activated carbon filter plate 73 can adsorb impurities in the sewage, thereby enhancing the purification effect of the sewage. The purified sewage can be discharged to the outside through the drain pipe 9, and the second water pump 63 can also be started to remove the purified sewage. The purified sewage is pumped into the dehydration cylinder 31 inside the dehydration box 1 through the water supply pipe 64, and then the dehydration cylinder 31 and the dehydration box 1 are cleaned. The cleaned sewage is again operated by the first water pump 61 and transported from the pumping pipe 62 to the purification box 2 for filtration and purification. When the quartz sand filter plate 71, the impurity removal filter plate 72 and the activated carbon filter plate 73 need to be replaced or cleaned, just hold the handles on the top of the quartz sand filter plate 71, the impurity removal filter plate 72 and the activated carbon filter plate 73 and slide them out of the placement slot 12 in turn.

[0030] Working principle: When using the rapid dehydration equipment for environmental protection projects, first discharge the sewage into the dehydration cylinder 31 inside the dehydration box 1 through the feed hopper 8, and then start the motor 34. The gear 33 rotates to make the toothed disc 32 drive the dehydration cylinder 31 to rotate, so that the sewage in the dehydration cylinder 31 can be quickly rotated and dehydrated. At this time, the sludge and debris remain in the dehydration cylinder 31, and the sewage enters the dehydration box 1 through the filter holes on the side wall of the dehydration cylinder 31. When the dehydration cylinder 31 rotates, the scraper 54 can continuously scrape off the sludge and debris attached to its inner wall. At the same time, the extrusion force generated by the scraper 54 causes the movable rod 53 to slide toward the inside of the connecting rod 52, and the spring 55 is compressed and deformed, thereby preventing the scraper 54 from being detached from the dehydration cylinder 31. 1 is damaged by long-term rigid contact. When the dehydration operation is completed, the solenoid valve 10 is opened to discharge the sludge and debris accumulated in the dehydration cylinder 31 to the external waste collection box through the discharge pipe 35, and then the first water pump 61 is started to pump the sewage in the dehydration tank 1 to the purification box 2 through the suction pipe 62, and then pass through the quartz sand filter plate 71, the impurity removal filter plate 72 and the activated carbon filter plate 73 for multiple filtration and purification in sequence. The purified sewage can be discharged to the outside through the drain pipe 9, or the second water pump 63 can be started to pump the sewage into the dehydration cylinder 31 inside the dehydration box 1 through the water supply pipe 64, and the dehydration cylinder 31 and the dehydration box 1 are cleaned. The cleaned sewage is again operated by the first water pump 61 and transported from the suction pipe 62 to the purification box 2 for filtration and purification.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
