Description

Technical Field

[0001] The utility model relates to the technical field of composite salt tablet processing, in particular to a potassium peroxymonosulfate composite salt tablet pressing and forming device. Background Art

[0002] Potassium persulfate complex salt tablets are also called potassium persulfate complex salts. They are triple salts formed by the combination of potassium monopersulfate, potassium hydrogen sulfate and potassium sulfate. They are non-chlorine complex active oxygen disinfectants and are widely used in aquaculture disinfection and drinking water disinfection. In order to ensure its solubility in water, tablet presses are often used to press effervescent tablets. During tablet pressing, due to the fine particle size of potassium persulfate complex salt powder and weak viscosity, the pressed tablets are less hard and easy to loosen. In the process of tablet pressing, the pressed tablets are generally allowed to fall freely into the finished product area for subsequent packaging operations. In this process, some drugs will be broken by impact, resulting in failure of finished product molding and reducing the qualified rate of finished products.

[0003] In Chinese patent CN215620216U, a high-speed tablet press for effervescent tablets is disclosed, which blocks the tablets rotating with the rotating forming disk through the limiting block on the lower tablet rod, so that the tablets are separated from the rotating forming disk and moved to the conveying mechanism, which can transport and convey the tablets. Compared with the free fall of tablets in the prior art, the tablets are collected and collided to cause breakage, which can effectively protect the integrity of the tablets, improve the tablet forming rate, and increase the production capacity. At the same time, in Chinese patent CN219381724U, a tablet forming device for potassium persulfate composite salt effervescent tablets is disclosed, which is further improved with respect to the above patents, and the beneficial effects achieved are: by arranging a protective cover on the conveying frame, the conveying frame and the protective cover form a relatively closed space, and a moisture absorption box is arranged in the protective cover, which can effectively remove moisture in the air, and prevent the potassium persulfate composite salt effervescent tablets from absorbing water and swelling to produce loose tablets, which affects the qualified rate of finished products.

[0004] However, in actual processing, since the device is passively hygroscopic, and the semi-open conveyor rack and protective cover are not ideal for tablets, outside air will still enter at will, and an effective dehumidification effect cannot be achieved within a limited stroke, and the practical significance is not obvious, especially for large-scale production of potassium permonosulfate complex salt tablets, which will affect the quality and pass rate of the finished product as a whole.

[0021] Figure 1-Figure 3The schematic diagram of the whole structure of the tablet forming device of potassium peroxymonosulfate composite salt tablet of the utility model is shown. Figure 1-Figure 3 A tablet forming device for potassium permonosulfate composite salt tablets in this embodiment includes a conveyor frame 10, an electrically driven conveyor belt 101 is provided inside the conveyor frame 10 along its length direction, a tablet press body 20 is provided at one end of the conveyor frame 10 and at the feeding end of the conveyor belt 101, a protective cover 30 is matched and covered on the upper end of the conveyor frame 10, and a discharge barrel 301 is provided at one end of the protective cover 30, an air collecting hood 40 arranged along the length direction of the protective cover 30 is fixed at the center of the inner side of the protective cover 30, and the air collecting hood 40 is arranged close to the hood and directly above the conveyor belt 101, an exhaust main pipe 50 is provided at the upper end of the protective cover 30, and a plurality of branch pipes 501 are provided at the bottom of the exhaust main pipe 50 along its length direction and connected to the air collecting hood 40, and an exhaust device 60 for exhausting the exhaust main pipe 50 is provided at the upper end of the protective cover 30.

[0022] Furthermore, the height of the outer port of the discharge barrel 301 is greater than the thickness of the composite salt effervescent tablet, and the outer port of the discharge barrel 301 corresponds to the output end of the conveyor belt 101. The discharge barrel 301 with a smaller port is conducive to the accurate discharge of the salt tablets, and at the same time can reduce the entry of outside air; the distance between the bottom of the air collecting hood 40 and the upper surface of the conveyor belt 101 is smaller than the thickness of the composite salt effervescent tablet, which can effectively improve the air collecting hood 40's suction efficiency of the air above the conveyor belt 101 and around the salt tablets, thereby removing moisture or humidity in the air.

[0023] The exhaust device 60 includes a blower 601 fixed to the upper end of the protective cover 30, an air inlet pipe 602 located at the air inlet end of the blower 601 and the other end of which is connected to the exhaust main pipe 50, an exhaust pipe 603 located at the air outlet end of the blower 601, and a dehumidifier 604 connected to the other end of the exhaust pipe 603. During use, the blower 601 forms a negative pressure suction force on the exhaust main pipe 50 through the air inlet pipe 602, and the exhaust main pipe 50 forms a negative pressure suction force on the entire air collecting hood 40 through the branch pipe 501. The inhaled air can enter the dehumidifier 604 through the exhaust pipe 603 for continuous dehumidification, and the dry air is discharged at the same time, thereby forming a good dehumidification cycle. During use, in order to prevent the composite salt tablets from being infiltrated with moisture due to being left in the air for a long time, the conveying channel is formed into a relatively closed space by the cooperation of the protective cover 30 and the conveying rack 10. At the same time, the exhaust device 60 will continuously exhaust, absorb moisture and dry the air in the conveying channel and around the salt tablets in the closed space through the exhaust main pipe 50, the branch pipe 501 and the air collecting hood 40, so that the overall dehumidification effect is effectively improved, and the finished product quality and product qualification rate of the composite salt tablets are further improved.

Desiccant boxes 70 are placed inside to effectively absorb moisture in the air in the channel, thereby enhancing the effect of auxiliary dehumidification. The covering edge between the protective cover 30 and the conveying rack 10 is also provided with a sealing strip. Here, the protective cover 30 and the conveying rack 10 are detachably installed. After installation, the sealing strip can seal the edge gap between the protective cover 30 and the conveying rack 10 to avoid direct contact between the conveying channel and the outside air as much as possible.

[0025] In summary, in the tableting and forming device of potassium permonosulfate composite salt tablets of the present embodiment, when in use, the salt tablets formed by the tablet press main body 20 will directly enter the conveyor belt 101 and the conveying channel, and at the same time, the blower 601 forms a negative pressure suction force on the exhaust main pipe 50 through the air inlet pipe 602, and the exhaust main pipe 50 forms a negative pressure suction force on the entire air collecting hood 40 through the branch pipe 501, and the inhaled air can enter the dehumidifier 604 through the exhaust pipe 603 for continuous dehumidification, and the dry air is discharged at the same time, thereby forming a good dehumidification cycle and achieving an effective dehumidification effect.
