Description

Technical Field

[0001] This utility model belongs to the field of sodium polyacrylate drying technology, and specifically relates to a closed-loop airflow structure for the purification and drying of sodium polyacrylate. Background Technology

[0002] Sodium polyacrylate is a water-soluble polymer compound with strong thickening and water-retaining properties. It is a widely used food additive with high purity, stable performance, and long shelf life. It is widely used in pasta, processed foods, and frozen foods.

[0003] Reference publication number CN218583572U discloses a drying chamber for the production of sodium polyacrylate, including a chamber body with an internal cavity. A drying plate is fixedly connected inside the chamber body, and the drying plate also has an internal cavity. An opening is located at the top of the drying plate, and a crushing roller is positioned on one side of the drying plate. This drying chamber for sodium polyacrylate production, through the coordinated use of a reciprocating motor, crushing roller, connecting frame, lead screw, and threaded sleeve, enables the device to crush and break down materials during drying, preventing clumping, reducing the difficulty of subsequent drying, and providing convenience for users. The reciprocating motor provides power, the crushing roller crushes the material, the connecting frame moves the crushing roller, the lead screw moves the threaded sleeve, and the threaded sleeve moves the connecting frame.

[0004] In the aforementioned patent, sodium polyacrylate is dried using two heating chambers. However, the air is directly discharged after drying. Since the dried air still has a certain amount of heat, direct discharge would result in energy waste. Furthermore, additional energy would be required to heat the cold outside air to the required drying temperature, leading to extra energy consumption.

[0005] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0006] To address the problems in related technologies, this invention proposes a closed-loop airflow structure for the purification and drying of sodium polyacrylate, thereby overcoming the aforementioned technical problems in existing related technologies.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a closed-loop airflow structure for purifying and drying sodium polyacrylate, including a drying chamber, a chamber body installed inside the drying chamber, air inlet chambers on the left and right sides of the chamber body, a drying chamber inside the chamber body and located between the two air inlet chambers, and a plurality of air outlet holes on the left and right inner walls of the drying chamber. A hot air chamber is installed at the bottom of the drying chamber. The hot air chamber is connected to the two air inlet chambers. An extension pipe is installed inside the hot air chamber. Several electrical sockets are provided on the inner wall of the extension pipe. A heating rod is installed on each electrical socket. A fan is installed on the top of the hot air chamber, and a connecting pipe is installed at the air inlet of the fan; A collection hopper is installed on the top of the chamber, and an exhaust pipe is connected to the top of the collection hopper. An installation mechanism is installed at the bottom of the exhaust pipe and at the top of the connecting pipe. A drying mechanism is installed between the two installation mechanisms. A main control unit is fixedly installed on the front of the drying chamber.

[0008] Furthermore, the inner cavity of the extension tube is arranged in a serpentine shape.

[0009] Furthermore, a support frame is installed at one end of the chamber to support the connecting pipe and the exhaust pipe.

[0010] Furthermore, the mounting mechanism includes two arc-shaped rings, each of which has a mounting ear fixedly mounted at both ends. The mounting ear has a through hole, and a screw is provided between the two aligned through holes.

[0011] Furthermore, a nut is threaded onto the outer wall of the screw, and a washer is fixedly installed on the inner ring of the arc-shaped ring.

[0012] Furthermore, the drying mechanism includes a drying tank, which contains a desiccant, and both ends of the drying tank are connected to installation pipes.

[0013] Furthermore, a shell plate is installed at the left end of the drying chamber, and a door is also installed at one end of the drying chamber.

[0014] This utility model has the following beneficial effects: This invention utilizes a fan to create suction within the collection hopper. The air, carrying moisture and still containing residual heat, is drawn into the collection hopper, then flows through the exhaust pipe, drying mechanism, and connecting pipe into the fan. Finally, the fan transports the air to the extension pipe, where several heating rods reheat the residual heat air. This allows the air, still containing residual heat, to participate in the heating and drying process again, avoiding the waste of energy caused by directly discharging the air containing residual heat into the outside air.

[0015] This invention uses a drying mechanism to absorb moisture from the hot air, making the hot air entering the connecting pipe dry, thus facilitating the subsequent heating of sodium polyacrylate with residual heat.

[0016] After the drying mechanism reaches saturation, the two mounting mechanisms are turned with a wrench or other tools to replace the drying mechanism, allowing the new drying mechanism to adsorb moisture from the hot air.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0022] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0023] Please see Figures 1-6 As shown, this utility model is a closed-loop airflow structure for purifying and drying sodium polyacrylate, including a drying chamber 1, a chamber body 2 installed inside the drying chamber 1, air inlet chambers 201 are opened on the left and right sides of the chamber body 2, a drying chamber 202 is opened inside the chamber body 2 and between the two air inlet chambers 201, and a plurality of air outlet holes 203 are opened on the left and right inner walls of the drying chamber 202. A hot air chamber 3 is installed at the bottom of the drying chamber 1. The hot air chamber 3 is connected to the two air inlet chambers 201. An extension pipe 4 is installed inside the hot air chamber 3. Several power sockets 5 are provided on the inner wall of the extension pipe 4. A heating rod 6 is installed on each power socket 5. A fan 7 is installed on the top of the hot air chamber 3, and a connecting pipe 8 is installed at the air inlet of the fan 7; The top of the chamber 2 is equipped with a collection hopper 9, and the top of the collection hopper 9 is connected to an exhaust pipe 10. The bottom of the exhaust pipe 10 and the top of the connecting pipe 8 are both equipped with an installation mechanism 11. A drying mechanism 12 is installed between the two installation mechanisms 11. A main control unit 13 is fixedly installed on the front of the drying chamber 1. The inner cavity of the extension pipe 4 is arranged in a serpentine shape.

[0024] The main controller 13 is electrically connected to several power sockets 5 and a fan 7 (model 7: PF-100-05). The main controller 13 can control the start and stop of the power sockets 5 and the fan 7. The main controller 13 controls the fan 7 to start, and then the fan 7 blows air into the inner cavity of the extension tube 4 in the hot air chamber 3. Then, several heating rods 6 on the power socket 5 heat the air, making it hot air. Since the inner cavity of the extension tube 4 is serpentine, the path of air heating is extended to ensure that the air can be fully heated. Then, the hot air enters and exits from the bottom of the extension tube 4 into the inner cavity of the hot air chamber 3, and finally enters the two air inlet chambers 201, and exits from several air outlets 203 into the drying chamber 202, and then performs the drying operation on the sodium polyacrylate. After the sodium polyacrylate is dried, the hot air absorbs the moisture contained in the sodium polyacrylate, becoming humid air carrying water vapor. The hot air still retains a certain amount of residual heat after drying the sodium polyacrylate and is not completely dissipated. At the same time, when the fan 7 is started, it will draw air from the connecting pipe 8, the drying mechanism 12, and the exhaust pipe 10, and generate suction in the collection hopper 9. This air carrying moisture and still containing residual heat will be drawn into the collection hopper 9, and then enter the fan 7 along the exhaust pipe 10, the drying mechanism 12, and the connecting pipe 8. Finally, it will be transported by the fan 7 to the extension pipe 4. Several heating rods 6 will reheat the residual heat air, and then the air with residual heat will participate in the heating and drying operation again, avoiding the direct discharge of the air with residual heat into the outside air, which would cause energy waste. When hot air carrying moisture enters the drying mechanism 12, the drying mechanism 12 can absorb the moisture in the hot air, making the hot air entering the connecting pipe 8 dry, thus facilitating the subsequent heating of sodium polyacrylate with residual heat. When the drying mechanism 12 reaches saturation, it needs to be replaced. The staff uses tools such as wrenches to loosen the two mounting mechanisms 11, so that the corresponding parts of the two mounting mechanisms 11 release the fixation of the two ends of the drying mechanism 12 on the connecting pipe 8 and the exhaust pipe 10. Then the old drying mechanism 12 is removed, and the new drying mechanism 12 is installed on the connecting pipe 8 and the exhaust pipe 10 through the two mounting mechanisms 11, so that it can once again absorb the moisture in the hot air.

[0025] In one embodiment, for the aforementioned chamber 2, a support frame 14 is installed at one end of the chamber 2 to support the connecting pipe 8 and the exhaust pipe 10.

[0026] The two support frames 14 can support the connecting pipe 8 and the exhaust pipe 10 to ensure that the connecting pipe 8 and the exhaust pipe 10 remain stable when the drying mechanism 12 is replaced.

[0027] In one embodiment, the mounting mechanism 11 includes two arc-shaped rings 1101, each of which has a mounting ear 1102 fixedly mounted at both ends. The mounting ear 1102 has a through hole 1103, and a screw 1104 is provided between the two aligned through holes 1103.

[0028] A nut 1105 is threaded onto the outer wall of the screw 1104, and a washer 1106 is fixedly installed on the inner ring of the arc-shaped ring 1101.

[0029] When the drying mechanism 12 needs to be disassembled, the operator uses a wrench or other tools to loosen the nuts 1105 at both ends of the screw 1104, causing the locking force between the two arc-shaped rings 1101 to be released. As the nuts 1105 gradually loosen, the gaskets 1106 of the inner rings of the arc-shaped rings 1101 disengage from the drying mechanism 12, releasing the clamping and fixing of the drying mechanism 12 at the connection of the connecting pipe 8 or the exhaust pipe 10. After the locking force is completely released, the saturated old drying mechanism 12 can be removed from between the connecting pipe 8 and the exhaust pipe 10. The new drying mechanism 12 is then aligned with the installation position between the connecting pipe 8 and the exhaust pipe 10, and the two arc-shaped rings 1101 are aligned... Align the two arc-shaped rings 1101 with the connecting pipe 8 or exhaust pipe 10, ensuring that the mounting ears 1102 at both ends of the arc-shaped ring 1101 are aligned and the corresponding through holes 1103 are coaxial. Insert the screw 1104 into the aligned through holes 1103 and tighten the nuts 1105 at both ends with a wrench. Drive the two arc-shaped rings 1101 to tighten inward until the gasket 1106 of the inner ring of the arc-shaped ring 1101 is tightly attached to the outer wall of the drying mechanism 12, thus achieving a firm fixation. When the upper end of the drying mechanism 12 is fixed to the exhaust pipe 10 and the lower end of the drying mechanism 12 is fixed to the connecting pipe 8, the new drying mechanism 12 can then perform its function of adsorbing moisture in the hot air.

[0030] In one embodiment, the drying mechanism 12 includes a drying tank 1201, which contains a desiccant 1202 and has an installation pipe 1203 connected to both ends of the drying tank 1201.

[0031] Air carrying moisture and still containing residual heat enters the drying tank 1201 through the exhaust pipe 10, then through the mounting pipe 1203 at the top of the drying tank 1201, and finally into the drying tank 1201. The desiccant 1202 inside the drying tank 1201 absorbs the moisture from the residual heat air, drying it. Finally, the air enters the connecting pipe 8 through the mounting pipe 1203 at the bottom of the drying tank 1201. It is important to note that the preferred desiccant is silica gel, activated alumina, or calcium chloride, etc. The drying tank 1201 is equipped with intercepting nets at both the top and bottom to trap the desiccant. Figure 6 As shown.

[0032] In one embodiment, for the drying chamber 1 described above, a shell plate 101 is installed at the left end of the drying chamber 1, and a chamber door 102 is also installed at one end of the drying chamber 1.

[0033] When the drying mechanism 12 needs to be disassembled, the shell plate 101 can be removed from the drying chamber 1 to facilitate the disassembly of the drying tank 1201. When the chamber door 102 is closed, it can seal the chamber body 2 to dry the sodium polyacrylate.

[0034] Working principle: The main controller 13 controls the start of the fan 7. The fan 7 blows air into the inner cavity of the extension tube 4 in the hot air chamber 3. Several heating rods 6 on the power base 5 heat the air, turning it into hot air. The hot air is then discharged from the bottom of the extension tube 4 into the inner cavity of the hot air chamber 3, and finally enters the two air inlet chambers 201. It is then discharged into the drying chamber 202 through several air outlets 203, and then the sodium polyacrylate is dried. At the same time, when the fan 7 starts, it will draw air from the connecting pipe 8, the drying tank 1201, and the exhaust pipe 10, and generate suction in the collection hopper 9. The dried hot air with moisture will be drawn into the collection hopper 9, and then enter the fan 7 along the exhaust pipe 10, the drying tank 1201, and the connecting pipe 8. Finally, it will be transported by the fan 7 to the extension pipe 4, where several heating rods 6 will reheat the residual heat air and participate in the heating and drying operation again. Air carrying moisture and still containing residual heat enters the drying tank 1201 through the exhaust pipe 10, then enters the drying tank 1201 through the mounting pipe 1203 at the top. The desiccant 1202 in the drying tank 1201 absorbs the moisture in the residual heat air, and finally enters the connecting pipe 8 through the mounting pipe 1203 at the bottom of the drying tank 1201. Once the desiccant 1202 reaches saturation, workers use wrenches and other tools to loosen the nuts 1105 at both ends of the screw 1104, thus releasing the locking force between the two arc-shaped rings 1101. This releases the clamping and fixing of the two mounting tubes 1203 at the connection between the connecting pipe 8 and the exhaust pipe 10. The saturated old desiccant 1202 outer drying canister 1201 is then removed from between the connecting pipe 8 and the exhaust pipe 10. The mounting tubes 1203 at both ends of the new drying canister 1201 are then connected to the connecting pipe 8. Align the two arc-shaped rings 1101 with the installation position between them and the exhaust pipe 10. Align the mounting ears 1102 at both ends of the arc-shaped rings 1101 with each other. Insert the screw 1104 into the aligned through hole 1103. Tighten the nuts 1105 at both ends with a wrench. Drive the two arc-shaped rings 1101 to tighten inward until the gasket 1106 of the inner ring of the arc-shaped ring 1101 is tightly attached to the outer wall of the mounting tube 1203. Wait for the two mounting tubes 1203 to be firmly fixed to the connecting tube 8 and the exhaust pipe 10 respectively.
