Description

TECHNICAL FIELD

[0001] The application relates to the technical field of material transportation, in particular to a feeding device for potassium dihydrogen phosphate purification reaction. BACKGROUND

[0002] Potassium dihydrogen phosphate (KH2PO4) is an important chemical product, which is deliquescent, and will melt into a transparent liquid when heated to 400 DEG C, and will solidify into an opaque glass-like potassium metaphosphate after cooling. Potassium dihydrogen phosphate is widely used in industry, including being used as a buffering agent, a culture agent, a bacterial culture agent, a seasoning agent for synthetic sake, a raw material for preparing potassium metaphosphate, a culture agent for brewing yeast, a fortifier, a bulking agent, a fermentation aid, etc. In agriculture, potassium dihydrogen phosphate, as a high-efficiency phosphorus-potassium compound fertilizer, has a significant effect on improving crop quality and increasing yield.

[0003] The spiral feeding device is a common material conveying equipment, which conveys materials from one end to the other end through rotating spiral blades. The device has the advantages of simple structure, convenient operation, high conveying efficiency, etc., and is widely used in various industrial fields. In the potassium dihydrogen phosphate purification reaction, the spiral feeding device plays a crucial role. Since the purification reaction has high requirements for the accurate metering and uniform conveying of raw materials, the spiral feeding device can accurately control the conveying amount of materials, ensure the smooth progress of the reaction, and ensure that the potassium dihydrogen phosphate is fed into the reaction container at a constant speed and amount, thereby realizing the continuity and stability of the feeding process.

[0004] However, in the existing spiral feeding device, the deliquescent property of potassium dihydrogen phosphate is its inherent chemical property, which can rapidly absorb water molecules in the air, especially in a high-humidity environment. This deliquescent property causes the potassium dihydrogen phosphate to easily become moist and caked in the spiral feeding device. The caked potassium dihydrogen phosphate significantly reduces its flowability in the device, because the caked material is difficult to be effectively pushed by the spiral blades. When the feeding amount is too large, especially at the feeding inlet, the accumulated potassium dihydrogen phosphate particles will be subjected to greater pressure, resulting in an increase in the contact area between the particles, so that the moist potassium dihydrogen phosphate is more likely to accumulate and form tight cakes. The cakes will rapidly expand and block the feeding inlet, causing the spiral feeding device to be unable to uniformly and continuously supply materials, which not only affects the production efficiency, but also causes the entire production line to stop. In addition, due to the moist characteristics of potassium dihydrogen phosphate, it will adhere to various parts of the spiral feeding device, such as the inner wall and spiral blades. Over a long period of time, the adhered material will accumulate into a thick cake, which will negatively affect the working efficiency of the feeding device. The adhered potassium dihydrogen phosphate will hinder the rotation of the spiral blades and reduce the feeding speed.

[0005] Therefore, the application provides a feeding device for potassium dihydrogen phosphate purification reaction. SUMMARY

[0017] Compared with the prior art, the present application has the following beneficial effects:

[0018] 1. When the pressing rod drives the abutting block to move downward, the abutting block moves upward under the elastic expansion of the compression spring when the pressing rod is not in contact with the abutting block, thereby realizing the vibration of the feeding shell. Since the potassium dihydrogen phosphate absorbs water molecules around when exposed to air, it becomes humid and forms clumps. At this time, the vibration of the feeding shell can help the relative movement between the potassium dihydrogen phosphate particles, thereby preventing them from being tightly combined together to form clumps. At the same time, the vibration of the feeding shell can accelerate the air flow inside, which helps to evaporate the water attached to the surface of the potassium dihydrogen phosphate, thereby promoting the drying of the potassium dihydrogen phosphate to a certain extent. Compared with the traditional motor-driven or pneumatic vibration system, the vibration of the feeding shell mainly depends on the elastic expansion of the compression spring. This design reduces the need for continuous driving energy, making the system more energy-efficient. At the same time, the quick response and recovery capability of the compression spring also ensures the efficiency of the vibration. At the same time, this vibration based on the compression spring reduces the direct contact and friction between mechanical parts, thereby reducing wear and noise.

[0019] 2. The continuous rotation of the rotating cross plate inside the feed housing loosens the potassium dihydrogen phosphate accumulated inside the feed housing, thereby reducing the risk of blockage in the feed section of the screw feeder. When the potassium dihydrogen phosphate remains loose, it is easier to be conveyed by the screw feeder, thereby improving the feeding efficiency and ensuring the continuity and stability of the production process. Due to the rotation of the rotating cross plate, the potassium dihydrogen phosphate always remains loose inside the feed housing, preventing the possibility of potassium dihydrogen phosphate clumping and blockage, thus ensuring the continuous and stable operation of the screw feeder.

[0020] 3. By repeatedly tapping the discharge pipe with a tapping rod, it is possible to effectively prevent potassium dihydrogen phosphate from forming clumps inside the discharge pipe, keeping the discharge pipe unobstructed and further reducing the risk of blockage. Because potassium dihydrogen phosphate is hygroscopic, it easily adheres to the inner wall of the feed housing and the discharge pipe. The tapping with the tapping rod can vibrate the inner wall of the discharge pipe, causing the adhered potassium dihydrogen phosphate to fall off. The tapping method is more advantageous than vibration when dealing with easily adhered materials, avoiding the situation where potassium dihydrogen phosphate adheres to the inner wall of the feed housing and the discharge pipe due to moisture, which would reduce the efficiency of subsequent purification reactions. In addition, traditional vibration cannot accurately act on certain key areas, while the tapping method can directly target specific areas or potential clumps in the discharge pipe, thereby more effectively preventing the formation of clumps and keeping the pipeline unobstructed.

[0021] 4. By rotating the fan, external gas is introduced into the spiral shell, increasing the airflow inside the spiral shell and preventing the potassium dihydrogen phosphate raw material from accumulating and clogging inside the spiral shell. This ensures smooth feeding and accelerates the evaporation of moisture from the surface of the potassium dihydrogen phosphate, keeping it dry and laying the foundation for subsequent purification reactions. When the fan rotates, the lower part is blocked, and the surface of the connecting groove in the upper part is equipped with tangential ring blocks. The opening of the groove allows the airflow to flow in a specific direction, avoiding excessive dispersion of the airflow and making the airflow more orderly and efficient. The tangential ring blocks allow the airflow to flow tangentially, further increasing the air volume and strengthening the air force, thereby more effectively preventing material accumulation and clogging, and accelerating moisture evaporation.

[0022] 5. By circumferentially arraying spiral shafts on the outer surface of the spiral blades, the rotation of the spiral blades drives the spiral shafts to rotate, thereby generating a stronger stirring force. This helps to disperse and mix the potassium dihydrogen phosphate inside the spiral shell, preventing material accumulation during feeding and ensuring smooth feeding. It also helps to propel the material forward and accelerate the processing speed of potassium dihydrogen phosphate. Attached Figure Description

[0053] During work:

[0054] Stir the potassium dihydrogen phosphate inside the feed housing 18:

[0055] The operator pours potassium dihydrogen phosphate into the feed housing 18 through the inlet 19. Under its own weight, the potassium dihydrogen phosphate falls from the feed housing 18 and then enters the spiral housing 1 along the inner wall of the outlet pipe 110. At this time, the operator manually starts the drive motor 11, which drives the rotating shaft 12 to rotate. The rotating shaft 12 then drives the spiral blades 13 to rotate. The potassium dihydrogen phosphate inside the spiral housing 1 is then transported from the end of the spiral housing 1 furthest from the outlet 14 to the outlet 14 by the movement of the spiral blades 13 and enters the purification container. In this process, the rotation of the rotating shaft 12 drives the drive helical gear 21, which is fixedly connected to it, to rotate. The drive helical gear 21 then drives the rotating helical gear 22, which meshes with it, to rotate. The rotating helical gear 22 then drives the rotating rod 23 to rotate on the support base 24. The internal rotation of the rotating rod 23 drives the rotating column 28 to rotate via the transmission of the conveyor belt 27. The rotation of the rotating column 28 drives the rotating cross plate 29 to rotate. The rotation of the rotating cross plate 29 agitates the potassium dihydrogen phosphate inside the feed housing 18. The continuous rotation of the rotating cross plate 29 inside the feed housing 18 loosens the accumulated potassium dihydrogen phosphate, thereby reducing the risk of blockage in the feed section of the screw feeder. When the potassium dihydrogen phosphate remains loose, it is easier to be conveyed by the screw feeder, thereby improving the feeding efficiency and ensuring the continuity and stability of the production process. Due to the rotation of the rotating cross plate 29, the potassium dihydrogen phosphate remains loose inside the feed housing 18, preventing the possibility of potassium dihydrogen phosphate agglomeration and blockage, thus ensuring the continuous and stable operation of the screw feeder.

[0056] Vibrate the feed housing 18:

[0057] In the above, the rotation of the rotating rod 23 drives the rotation of the rotating helical gear 38 fixedly connected to it. The rotation of the rotating helical gear 38 drives the rotation of the matching helical gear 37. The rotation of the matching helical gear 37 drives the linkage rod 36 to rotate inside the vibrating housing 32. The rotation of the linkage rod 36 drives the rotating plate 34 on the side away from the linkage rod 33 to rotate. The rotation of the rotating plate 34 on the side away from the linkage rod 33 drives the connecting rod 35 to rotate around the axis of the linkage rod 36. The rotation of the connecting rod 35 drives the rotating plate 34 on the side close to the linkage rod 33. The rotation of the rotating plate 34 on the side close to the linkage rod 33 drives the linkage rod 33 to rotate. As the connecting rod 35 rotates around the axis of the linkage rod 36, it drives the pressing rod 39 to rotate around the connecting rod 35 as a fulcrum. While rotating, the lower pressure rod 39 reciprocates up and down. It rotates around the connecting rod 35 as a fulcrum. Because the lower pressure rod 39 is slidably connected inside the vibrating housing 32, the lower pressure rod 39 on the side furthest from the connecting rod 35 will have its rotation restricted. Consequently, the rotation of the lower pressure rod 39 closer to the connecting rod 35 will be synchronous with the rotation trajectory of the connecting rod 35, while the lower pressure rod 39 on the side furthest from the connecting rod 35 will only reciprocate up and down inside the vibrating housing 32. The reciprocating up and down movement of the lower pressure rod 39 drives the stabilizing shaft 310 and the connecting support plate 311 to reciprocate up and down synchronously. The reciprocating up and down movement of the connecting support plate 311 drives the contact block 312 to slide up and down inside the sliding housing 313. Simultaneously, when the contact block 312 moves downwards, it will squeeze the feed housing 18. The feed housing 18 moves downwards synchronously, causing the connecting shaft 317 to move downwards as well. This downward movement of the connecting shaft 317 compresses the compression spring 316. Simultaneously, the downward movement of the feed housing 18 causes sliding groove one 318 and sliding groove two 320 to move downwards synchronously. At this time, sliding rod one 319 and sliding rod two 321 will slide downwards in sliding groove one 318 and sliding groove two 320 respectively. Sliding rod one 319 will no longer be at its lowest position inside sliding groove one 318, and sliding rod two 321 will no longer be at its lowest position inside sliding groove two 320. Subsequently, when the contact block 312 moves upwards, the above movement will return to its initial state under the elastic extension of the compression spring 316. The downward pressure of the pressing rod 39 causes the contact block 312 to move downward. When the pressing rod 39 is not in contact with the contact block 312, the contact block 312 moves upward under the elastic extension of the compression spring 316, thereby achieving vibration of the feed housing 18. Since potassium dihydrogen phosphate absorbs surrounding water molecules when exposed to air, it becomes damp and clumps. At this time, the vibration of the feed housing 18 can help generate relative movement between potassium dihydrogen phosphate particles, thereby preventing them from tightly binding together and forming clumps. At the same time, the vibration of the feed housing 18 can accelerate the airflow inside, which helps to evaporate the moisture attached to the surface of potassium dihydrogen phosphate, thereby promoting the drying of potassium dihydrogen phosphate to a certain extent. Compared with traditional motor-driven or pneumatic vibration systems, this method is more efficient.The vibration of the feed housing 18 primarily relies on the elastic extension of the compression spring 316. This design reduces the continuous drive energy requirement, making the system more energy-efficient. Simultaneously, the rapid response and recovery capability of the compression spring 316 ensures high vibration efficiency. Furthermore, this vibration based on the compression spring 316 reduces direct contact and friction between mechanical components, thereby reducing wear and noise generation.

[0058] Tap the discharge pipe 110:

[0059] In the above description, the rotation of the rotating rod 23 drives the rotating ring 410, which is fixedly connected to it, to rotate. The rotation of the rotating ring 410 drives the protrusions symmetrically fixedly connected to its outer surface to move synchronously. The rotation of the protrusions of the rotating ring 410 will abut against the locking block 49 and drive the locking block 49 to rotate around the center of the rotating rod 23. The rotation of the locking block 49 drives the adapter ring 48 to rotate. The rotation of the adapter ring 48 drives the push rod 47 to rotate around the center of the rotating rod 23. The rotation of the push rod 47 drives the connecting tube 46, which is fixedly connected to it, to rotate synchronously. The rotation of the connecting tube 46 drives the striking rod 43 to rotate. The striking rod 43 is slidably connected inside the striking housing 42. During the rotation, the connecting tube 46 itself is displaced. The rotation of the connecting tube 46 will cause the striking rod 43 to slide inside the striking housing 42 away from the discharge pipe 110. At this time, the striking rod 43 no longer abuts against the outer surface of the discharge pipe 110. The sliding of the striking rod 43 causes the blocking block 44 fixedly connected to it to move synchronously. The movement of the blocking block 44 causes the return spring 45 to be compressed. When the locking block 49 rotates ninety degrees, since the outer surface of the adapter ring 48 is set to be elliptical, as the adapter ring 48 rotates, the edge of the locking block 49 has moved away from the protrusion. The locking block 49 will no longer abut against the protrusion on the rotating ring 410. Under the elastic extension of the return spring 45, the return spring 45 will drive the blocking block 44 to move closer to the discharge pipe 110. The movement of the blocking block 44 causes the striking rod 43 to slide inside the striking housing 42 towards the end closer to the discharge pipe 110. At this time, the striking rod 43 abuts against the outer surface of the discharge pipe 110 and strikes the outer surface of the discharge pipe 110. Simultaneously, as the striking rod 43 slides, it causes the pushing rod 47 to rotate towards the end closer to the striking housing 42. The rotation of the pushing rod 47 causes the adapter ring 48 to rotate to a stationary state. The rotation of the adapter ring 48 causes the locking block 49 to rotate synchronously to a stationary state. As the rotating rod 23 continues to rotate, the striking rod 43 will slide back and forth and continuously strike the outer wall of the discharge pipe 110. By repeatedly striking the discharge pipe 110 with the striking rod 43, the formation of potassium dihydrogen phosphate in the discharge pipe 110 can be effectively prevented. To prevent blockages, the tapping rod 43 can vibrate the inner wall of the discharge pipe 110 to remove the attached potassium dihydrogen phosphate. Since potassium dihydrogen phosphate is hygroscopic, it easily adheres to the inner wall of the feed housing 18 and the discharge pipe 110. This tapping method is more advantageous than vibration when dealing with easily adhered materials, preventing potassium dihydrogen phosphate from adhering to the inner wall of the feed housing 18 and the discharge pipe 110 due to moisture, thus reducing the efficiency of subsequent purification reactions. Furthermore, traditional vibration cannot precisely target certain key areas, while the tapping method can directly target specific areas or potential agglomeration points in the discharge pipe 110, thereby more effectively preventing agglomeration and keeping the pipe unobstructed.

[0060] Ventilate the interior of spiral shell 1:

[0061] During the stirring of potassium dihydrogen phosphate inside the feed housing 18, the drive motor 11 starts and drives the rotating shaft 12 to rotate. The rotation of the rotating shaft 12 drives the rotating fan 53 to rotate. The rotation of the rotating fan 53 causes external gas to enter the assembly tank 51 from the air inlet slot 52. The airflow inside the assembly tank 51 enters the spiral housing 1 along the connecting slot 56. Since the lower half of the air outlet inside the assembly tank 51 is blocked, the airflow is mainly guided to the upper half, reducing the area of ​​the air outlet. According to Bernoulli's principle, when air passes through a narrower channel, its speed increases, thus forming a higher wind speed at the air outlet. Furthermore, the surface of the connecting slot 56 in the upper half is provided with... The tangential ring block 54, with its grooves, allows the airflow to flow in a specific direction, preventing excessive dispersion and making the airflow more orderly and efficient. The tangential ring block 54 also causes the airflow to flow tangentially, creating a turbine-like effect that further increases air volume and strengthens the airflow. By rotating the fan 53, external gas is introduced into the spiral shell 1, increasing the airflow inside the spiral shell 1 and preventing the potassium dihydrogen phosphate raw material from accumulating and clogging inside the spiral shell 1, ensuring smooth feeding. At the same time, the flowing airflow can accelerate the evaporation of moisture on the surface of potassium dihydrogen phosphate, keeping it dry and laying the foundation for subsequent purification reactions.

[0062] Stirring the inside of the spiral shell 1:

[0063] During the stirring of potassium dihydrogen phosphate inside the feed housing 18, the rotating shaft 12 drives the spiral blades 13 to rotate. The rotation of the spiral blades 13 drives the spiral shaft 55 to rotate synchronously around the center of the spiral blades 13. The rotation of the spiral shaft 55 generates a stronger stirring force, which helps to disperse and mix the potassium dihydrogen phosphate inside the spiral housing 1, prevents the material from accumulating during the feeding process, ensures the smooth progress of the feeding process, and also helps to push the material forward, thus accelerating the processing speed of potassium dihydrogen phosphate.
