Description

Technical Field

[0001] The present application relates to the field of aquaculture technology, and in particular to a composite processing device for potassium persulfate composite salt tablets used in aquaculture. Background Art

[0002] Aquaculture is an important protein supply industry, but under the high-density farming model, organic matter such as leftover bait, feces, and dead algae continue to accumulate at the bottom of the pond, causing the bottom to become black and smelly, dissolved oxygen to decrease, ammonia nitrogen / nitrite to exceed the standard, and the breeding of bacteria, viruses and some parasites, which seriously threaten the health of farmed organisms.

[0003] At present, potassium persulfate complex salt is gradually being used in the field of aquaculture as a disinfectant and bottom improver. It releases active oxygen, oxidizes and decomposes organic matter, and reduces harmful substances such as ammonia nitrogen and hydrogen sulfide.

[0004] In order to facilitate administration, powdered potassium persulfate complex salt is usually pressed into tablets through a tablet press, so that the tablets sink to the bottom and then slowly disintegrate. However, during the tablet press processing, if the pressure of the material is adjusted to a small amount, the formed tablets will become loose. After being put into water, it will not only affect the sinking, but also cause the active ingredients to be released instantly, affecting the effect; if the pressure of the material is increased, the formed tablets will be compacted. Although it can enhance the sinking property, it will affect the disintegration time. Therefore, the present application proposes a new technical solution. Summary of the Invention

[0021] The following is combined with Figure 1-5 This application is described in further detail.

[0022] The embodiment of the present application discloses a composite processing device for potassium persulfate composite salt tablets used in aquaculture.

[0023] Reference Figure 1 and Figure 2 The composite processing device of potassium persulfate composite salt tablets used in aquaculture includes a frame 1, an initial pressing mold 2, a secondary pressing mold 3, a loading and unloading mechanism 4, an adsorption mechanism 5, a pressing mechanism 6 and a controller.

[0024] In the present application, the powder material is loaded into the initial compression mold 2 by the loading and unloading mechanism 4, the powder material is initially compressed into tablets by the pressing mechanism 6, and then the tablets are transferred to the re-compression mold 3 by the adsorption mechanism 5, and the tablets are supplemented by the loading and unloading mechanism 4, and then re-compressed by the pressing mechanism 6, so that the outer layer of the originally formed initial compression tablet is re-compressed, and the pressure of the initial compression is different from the pressure of the re-compression, so that the tablets can disintegrate in stages, delaying the disintegration time, and improving the bottom improvement effect on aquaculture waters.

[0025] The specific settings are as follows: The frame 1 is used to support the entire device. The primary pressing mold 2 is fixed to the work surface of the frame 1, and the primary pressing mold 2 is provided with a plurality of primary pressing mold holes 21 for accommodating powder materials along the longitudinal direction. The secondary pressing mold 3 is located on the upper surface of the primary pressing mold 2, and the secondary pressing mold 3 is provided with a plurality of secondary pressing mold holes 31 along the longitudinal direction, and the positions of the secondary pressing mold holes 31 and the primary pressing mold holes 21 correspond one to one, and the opening width of the secondary pressing mold holes 31 is greater than the width of the primary pressing mold holes 21. The frame 1 is equipped with a drive component 2, which is used to move the secondary pressing mold 3 so that the secondary pressing mold holes 31 can be aligned with the primary pressing mold holes 21. The drive component 2 is electrically connected to the controller. In this embodiment, the drive component 2 can be a micro cylinder, and the cylinder output end is connected to one end of the secondary pressing mold 3.

[0026] Reference Figure 2 and Figure 3 The loading and unloading mechanism 4 includes a material collection box 41 attached to the upper surface of the re-pressing mold 3 and a driving component 1 for driving the material collection box 41 to move. In this embodiment, the driving component 1 can be a cylinder. The interior of the material collection box 41 is hollow and has openings at the upper and lower ends. A plurality of scrapers 42 attached to the upper surface of the re-pressing mold 3 are fixed on the inner wall of the material collection box 41. The plurality of scrapers 42 are arranged at intervals along the moving direction of the material collection box 41. The cross-section of the scraper 42 is V-shaped, and a connecting groove 43 for powder transition is provided at the bottom of the scraper 42.

[0027] Through the above-mentioned setting, the powder material can be poured into the collecting box 41. At this time, the re-pressing mold 3 is in the initial position, that is, the re-pressing mold hole 31 is misaligned with the initial pressing mold hole 21. The collecting box 41 is moved by driving component 1, and the collecting box 41 is moved from one end of the re-pressing mold 3 to the other end, so that the powder material in the collecting box 41 is fed into the re-pressing mold hole 31, and through the action of the scraper 42, each re-pressing mold hole 31 can be filled with powder material. Then, the re-pressing mold 3 is moved by controlling driving component 2 to align the re-pressing mold hole 31 with the initial pressing mold hole 21, so that the powder material in the re-pressing mold hole 31 is poured into the initial pressing mold hole 21. By arranging the loading and unloading mechanism 4, the re-pressing mold 3 and the initial pressing mold 2 in layers, not only can space be saved, but also the loading and unloading of the re-pressing mold 3 and the initial pressing mold 2 can be realized in sequence.

[0028] Considering that when the tablet is subjected to secondary compression, in order to ensure that the tablet is surrounded by powder material, so that the outer layer of the initially compressed tablet can be completely covered with another layer after the secondary compression, the adsorption mechanism 5 is required to suck the initially compressed tablet out of the primary compression die hole 21. At the same time, in order not to change the horizontal position of the pressing mechanism 6, it is only necessary to maintain the vertical pressing action. Therefore, when the tablet in the secondary compression die hole 31 and the subsequently fed powder material are compressed together, the secondary compression die hole 31 needs to be separated from the primary compression die hole 21. The arrangement is as follows: Reference Figure 2and Figure 4 A slot 32 is provided in the horizontal direction at the bottom of the re-pressing mold 3, and a horizontal plug plate 33 is slidably inserted in the slot 32. A driving component three for moving the plug plate 33 is installed on the side of the re-pressing mold 3. In this embodiment, the driving component three can be a micro cylinder (not shown in the figure). The plug plate 33 is provided with through holes 34 corresponding to the positions of the re-pressing mold holes 31, and configuration holes 35 are provided on the same side of the plug plate 33 where each through hole 34 is located. A partition 36 is placed in the configuration hole 35. The diameter of the partition 36 is adapted to the diameter of the re-pressing mold hole 31, so that the partition 36 can fall into the re-pressing mold hole 31, but the diameter of the partition 36 is larger than the diameter of the initial pressing mold hole 21, thereby blocking the material from entering the initial pressing mold hole 21.

[0029] The position status of the plugboard 33 is described as follows: When the powder material in the primary compression die hole 21 is compressed, the through hole 34 on the insert plate 33 is aligned with the secondary compression die hole 31 and the primary compression die hole 21. When secondary compression is required, the drive assembly 3 moves the insert plate 33 to align the configuration hole 35 on the insert plate 33 with the secondary compression die hole 31, so that the partition 36 in the configuration hole 35 falls into the secondary compression die hole 31, acting as a material barrier. The powder is then fed into the secondary compression die hole 31 by the loading and unloading mechanism 4. The adsorption mechanism 5 then releases the tablet, and the pressing mechanism 6 presses down.

[0030] Reference Figure 2 In order to reset the partition 36 and push the re-pressed tablet out of the re-pressing die hole 31, the frame 1 is provided with a reset assembly. The reset assembly includes a plurality of reset rods 7 and a drive assembly 4. Each reset rod 7 corresponds to a primary pressing die hole 21. The reset rod 7 slides from the lower end of the primary pressing die 2 and penetrates into the primary pressing die hole 21. The lower ends of all reset rods 7 are fixed together on a horizontal plate. The drive assembly 4 can be a cylinder. The cylinder is installed on the frame 1 and its output end is connected to the lower end of the horizontal plate. The reset rod 7 is moved upward by the drive assembly 4 so that the reset rod 7 can push the tablet obtained after re-pressing out of the re-pressing die hole 31 through the partition 36. Then, the partition 36 is moved to a height flush with the configuration hole 35 of the insert plate 33. The drive assembly 3 moves the insert plate 33 so that the insert plate 33 moves the partition 36 out of the re-pressing die hole 31 through the configuration hole 35 and returns it to its original position.

[0031] Based on the above foundation, the controller is electrically connected to the loading and unloading mechanism 4, the adsorption mechanism 5 and the pressing mechanism 6; The controller configuration is: S100, when a processing instruction triggered by a user is received, the loading and unloading mechanism 4 is controlled to execute the loading instruction 1, which includes: S101, when a processing instruction triggered by a user is received, the driving component 1 is controlled to move the collecting box 41; S102, when a feedback signal is received after the driving component 1 completes the corresponding instruction, the driving component 2 is controlled to move the re-pressing mold 3; It can be understood that the processing instruction can be through a processing start button preset on the PLC control cabinet, and the button is connected to the PLC through a circuit; the driving component one moves the material collection box 41, which means moving the material collection box 41 from one end of the re-pressing mold 3 to the other end of the re-pressing mold 3; the driving component two moves the re-pressing mold 3, which means moving the re-pressing mold 3 in the initial position, so that the re-pressing mold hole 31 is aligned with the initial pressing mold hole 21, so that the material in the re-pressing mold hole 31 falls into the initial pressing mold hole 21, thereby adding the material to the initial pressing mold hole 21.

[0032] S200, then controlling the pressing mechanism 6 to execute the initial pressure instruction according to the preset pressure parameter f1; It can be understood that the initial compression instruction refers to compressing the powder in the initial compression die hole 21 into tablets, and the pressure parameter f1 can be a pressure parameter required for a relatively ideal tablet disintegration time obtained by staff through experiments.

[0033] S300, then controlling the adsorption mechanism 5 to execute the tablet transfer instruction; It can be understood that the tablet transfer instruction means that the adsorption mechanism 5 sucks the tablet out of the primary compression die hole 21 .

[0034] S400, then control the driving component 3 to move the insert plate 33, so that the partition plate 36 falls into the re-pressing die hole 31; S500, then controlling the loading and unloading mechanism 4 to execute the loading instruction 2, controlling the adsorption mechanism 5 to execute the tablet release instruction, and controlling the pressing mechanism 6 to execute the re-pressing instruction according to the preset pressure parameter f2; wherein f2 < f1; It can be understood that the second loading instruction refers to moving the aggregate box 41 and putting the powder material into the re-pressing die hole 31. The pressure parameter f2 is obtained by the staff through experiments. It is able to press the subsequent loaded powder and the tablet obtained by the initial pressing into a tablet together without being too loose.

[0035] S600, then controlling the reset component to push the tablet out of the reset die hole; S700, then control the loading and unloading mechanism 4 to execute the unloading instruction; It can be understood that the unloading instruction refers to the drive component driving the aggregate box 41 to move (before moving, the aggregate box 41 is located at the initial end of the re-pressing mold 3, and all tablets are located outside the aggregate box 41), so that the outer wall of the aggregate box 41 pushes all tablets down.

[0036] S800, then control the reset component to move the partition 36 into the configuration hole 35, and control the driving component to reset.

[0037] Reference Figure 5Regarding the pressing mechanism 6, it includes an initial pressing head 61 adapted to the initial pressing die hole 21, a compound pressing head 62 adapted to the compound pressing die hole 31, and a power unit. The width of the compound pressing head 62 is greater than the width of the initial pressing head 61. The power unit is fixed to the frame 1 and is located above the loading and unloading mechanism 4. The power unit includes a hydraulic cylinder and an air pump. The power output end of the hydraulic cylinder is fixed to the compound pressing head 62. An air cavity 63 for accommodating the initial pressing head 61 is provided inside the compound pressing head 62. The initial pressing head 61 is connected to the air cavity 63 by sliding longitudinally. The first power output interface of the air pump is connected to the air cavity 63 through an air pipe, which is used to drive the initial pressing head 61 to extend out of the compound pressing head 62 when the initial pressing head 61 is needed, and to drive the initial pressing head 61 to be retracted into the air cavity 63 of the compound pressing head 62 when the compound pressing head 62 is needed.

[0038] The adsorption mechanism 5 includes an air cavity 2 51 opened inside the re-pressure head 62, an air channel 52 opened inside the initial pressure head 61, the air channel 52 is connected to the air cavity 2 51, and the end surface of the initial pressure head 61 extending out of the re-pressure head 62 is provided with a plurality of adsorption holes connected to the air channel 52, and the air cavity 2 51 is connected to the second power output interface of the air pump through an air pipe.

[0039] In another embodiment of the present application, in order to push the tablet into the powder material when it is necessary to release the tablet into the re-pressing die hole 31 filled with powder material, so that the upper surface of the tablet can also be covered with powder material, so that the outer layer of material can completely wrap the tablet as much as possible, the following is set: Reference Figure 5 A cavity 53 is provided at the lower end of the initial pressure head 61, and the cavity 53 is connected to the airway 52. ​​A horizontal built-in plate 54 is slidably provided in the cavity 53, and the built-in plate 54 is provided with air holes. A vertical push pin 55 is fixedly connected to the side of the built-in plate 54 facing the outside of the initial pressure head 61.

[0040] When it is necessary to adsorb the tablet, the air pump is controlled to pump air, and the gas enters the cavity 53 through the adsorption hole and the air hole, passes through the air channel 52, and finally enters the air cavity 2 51. At this time, the end face of the initial pressure head 61 adsorbs the tablet, and the push pin 55 retracts into the interior of the initial pressure head 61; when it is necessary to release the tablet, the air pump is controlled to stop pumping air, and the tablet falls on the powder material in the re-pressing die hole 31. At the same time, due to the action of gravity, the built-in plate 54 and the push pin 55 move downward, and the push pin 55 extends out of the lower end face of the initial pressure head 61, so that the tablet can be pushed into the powder material, so that the powder material can be covered above the tablet, thereby making the re-pressing effect better and being able to better wrap the initial compressed tablet; then the air pump drives the initial pressure head 61 to retract into the air cavity 1 63 of the re-pressing head 62, and the hydraulic cylinder drives the re-pressing head 62 to press down as a whole.

[0041] It should be noted that, whether using the initial pressure head 61 or the secondary pressure head 62 to press down the material, after the push pin 55 contacts the material, the air pump will not hinder the movement of the push pin 55, and the push pin 55 will retract into the cavity 53 of the initial pressure head 61 and will not interfere with tableting.

[0042] In another embodiment of the present application, a spring may be provided between the built-in plate 54 and the cavity 53 , so that the push pin 55 can better push the tablet into the powder material through the elastic force of the spring.

[0043] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
