[0017] 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.
[0018] Reference Figures 1-3This utility model provides an embodiment of an automatic titration disinfectant device for washing citrus fruits, comprising a washing tank 5, a top plate 8 fixedly connected to the left side of the washing tank 5, and a storage tank 2 connected to the top side of the top plate 8 for storing disinfectant. Two fixing rods 19 are fixedly connected to the inner wall of the storage tank 2, and a ring 20 is fixedly connected between the two fixing rods 19. A stirring rod 13 is rotatably connected inside the ring 20, and multiple stirring blades 14 are fixedly connected to the outer wall of the stirring rod 13. The stirring rod 13 drives the stirring blades 14 to move... The disinfectant solution is rotated in the storage tank 2 to agitate it, ensuring uniform mixing during storage and preventing sedimentation or stratification. The cleaning tank 5 has two rotating spiral shafts 7 with multiple evenly distributed spiral blades. These shafts rotate the blades, agitating the disinfectant solution dripping into the cleaning tank 5 and allowing it to spread more quickly to all parts of the tank. The spiral blades are made of food-grade plastic to prevent damage to citrus fruits during agitation. (Refer to...) Figure 1 , Figure 4 and Figure 6 A ring 17 is fixedly connected to the bottom side of the liquid storage tank 2. Two insert plates 18 are fixedly connected to the outer wall of the ring 17. An annular groove and two slots are provided on the top side of the top plate 8. The ring 17 is inserted into the annular groove and the insert plates 18 are inserted into the slots. The insert plates 18 are inserted into the slots by inserting the ring 17 into the annular groove. A baffle 21 is slidably connected inside the slot. Elastic pads 22 are fixedly connected to the upper and lower sides of one end of the baffle 21. The end of the baffle 21 is inserted into the slot and the elastic pads 22 are engaged inside the slot. The baffle 21 is slidably connected to the end of the baffle 21 with the elastic pads 22 into the slot, so that the elastic pads 22 are engaged in the slot. Thus, the baffle 21 blocks the insert plates 18, so that the liquid storage tank 2 is fixed to the top plate 8.
[0019] Reference Figure 1 , Figure 3 and Figure 5Gears 12 are fixedly connected to the left end of the front spiral blade shaft 7 and the bottom end of the stirring rod 13. The two gears 12 mesh with each other. A first protective shell 4 is fixedly connected to the left side of the cleaning tank 5. The gears 12 are located inside the first protective shell 4. The meshing gears 12 cause the front spiral blade shaft 7 to rotate, driving the stirring rod 13 to rotate. The first protective shell 4 protects the gears 12, preventing dirt or water stains from falling onto the gears 12 and affecting their transmission. A pulley 11 is fixedly connected to the right end of the spiral blade shaft 7. Two pulleys 11... The two parts are connected by the inner side of a belt. A second protective shell 6 is fixedly connected to the right side of the cleaning tank 5. The pulley 11 is located inside the second protective shell 6. The two pulleys 11 connected by the belt cause the rear spiral blade shaft 7 to rotate, which in turn drives the front spiral blade shaft 7 to rotate. The second protective shell 6 protects the pulleys 11 and the belt, preventing dirt or water stains from falling between the pulleys 11 and the belt and affecting its transmission. A motor 9 is installed on the left side of the rear side of the cleaning tank 5. The drive end of the motor 9 is fixedly connected to the left end of the rear spiral blade shaft 7. The motor 9 drives the rear spiral blade shaft 7 to rotate. A waterproof motor can be selected as needed, or a protective cover can be added to the motor 9 to prevent water damage. A drain pipe 10 is fixedly connected to the rear side of the cleaning tank 5, and a drain pipe 3 is fixedly connected to the bottom side of the storage tank 2. A cover plate 1 is provided on the top side of the storage tank 2. The wastewater generated during cleaning in the cleaning tank 5 is discharged through the drain pipe 10. A replenishment port can be opened on the cover plate 1 for convenient replenishment of disinfectant, or the cover plate 1 can be opened directly to replenish disinfectant. The wastewater generated during cleaning is discharged through the drain pipe 3. Wastewater from storage tank 2 is discharged from storage tank 2. A peristaltic pump 15 is installed on the right side of storage tank 2. A burette 16 is fixedly connected to the output end of the peristaltic pump 15. The burette 16 is located above the cleaning tank 5. The peristaltic pump 15 controls the amount of disinfectant dripped into the cleaning tank 5, and the burette 16 drips the disinfectant into the cleaning tank 5. Sealing rings are provided at each rotating structure in the above device to prevent liquid from entering the rotating connection and affecting the rotation, such as the rotating connection between the spiral blade shaft 7 and the cleaning tank 5, and the rotating connection between the stirring rod 13 and the storage tank 2.
[0020] Working principle: First, insert the insertion ring 17 on the storage tank 2 into the annular groove so that the insertion plate 18 is inserted into the slot. Then, slide the baffle 21 so that one end of the baffle 21 with the elastic pad 22 is inserted into the slot, thereby making the elastic pad 22 engage in the slot. This causes the baffle 21 to block above the insertion plate 18, thus fixing the storage tank 2 to the top plate 8. Then, add clean water and fruit to the cleaning tank 5. Then, start the motor 9 and the peristaltic pump 15. The peristaltic pump 15 controls the amount of disinfectant dripped into the cleaning tank 5, and the disinfectant is dripped into the cleaning tank 5 through the burette 16. The motor 9 drives the rear spiral blade shaft 7 to rotate. Then, the two pulleys 11 connected by belts drive the front spiral blade shaft 7 to rotate, thereby causing the spiral blade shaft 7 to rotate and agitate the disinfectant dripped into the cleaning tank 5, allowing it to diffuse more quickly. At each position, when the front spiral blade shaft 7 rotates, the meshing gears 12 cause the front spiral blade shaft 7 to rotate, which in turn drives the stirring rod 13 to rotate. This causes the stirring rod 13 to drive the stirring blade 14 to rotate in the storage tank 2, thereby agitating the disinfectant and keeping it evenly mixed during storage to avoid sedimentation or stratification. After cleaning, the wastewater generated in the cleaning tank 5 is discharged through the drain pipe 10, and the fruit is removed from the cleaning tank 5, thus completing one work cycle. When the storage tank 2 needs to be cleaned, the sliding baffle 21 is used to disengage the baffle 21 from the insert plate 18, and then the storage tank 2 is pulled upward to disengage the insert ring 17 from the annular groove and the insert plate 18 from the slot. Then, the new storage tank 2 is fixed to the top plate 8 to continue the disinfection work. When cleaning the storage tank 2, the wastewater from cleaning the storage tank 2 can be discharged through the drain pipe 3.
