For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood through the specific circumstances.

[0029] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a high-efficiency and energy-saving hot air circulating dryer, comprising:

[0031] Drying chamber 1, which is equipped with a hot air circulation mechanism;

[0032] The hot air circulation mechanism includes a main pipe 6, an air supply pipe 7, a connecting column 11, a rotating head 12, a plug rod 14, a cylinder 15, a moisture-absorbing sponge 16, a positioning component 17, and a spring 19;

[0033] The air supply duct 7 is fixedly installed on the dryer box 1 and the main pipe 6. The insertion rod 14 is engaged with the rotating head 12. The insertion rod 14 is fixedly connected to the cylinder 15. The moisture-absorbing sponge 16 is fixedly installed inside the cylinder 15. The positioning part 17 is slidably installed on the rotating head 12. The positioning part 17 is engaged with the connecting column 11 and the insertion rod 14. The connecting column 11 is fixedly installed on the dryer box 1. The rotating head 12 is rotatably installed on the connecting column 11. It should be noted that the rotating head 12 can be rotatably connected to the connecting column 11 through a bearing.

[0034] Spring 19 is fixedly installed between positioning part 17 and rotating head 12.

[0035] Through the aforementioned hot air circulation mechanism, sodium carboxymethyl cellulose can flow downwards sequentially on multiple guide plates 3, and then hot air is evenly delivered into the drying chamber 1 through multiple air supply pipes 7. This ensures that the sodium carboxymethyl cellulose flowing on the guide plates 3 is dried evenly, guaranteeing the drying effect. Moreover, the moisture generated after drying is absorbed by the moisture-absorbing sponge 16, which effectively removes moisture and ensures the drying effect. After a period of use, the positioning element 17 can be pulled, which stretches the spring 19, causing the positioning element 17 to move out of the positioning groove 18. At this time, the rotating head 12 can be rotated to switch to an adjacent moisture-absorbing sponge 16 for use. The rotating head 12 is limited by the positioning element 17 being inserted into the positioning groove 18. After multiple moisture-absorbing sponges 16 have been used, the positioning element 17 can be pulled, causing it to move out of the insertion hole on the insertion rod 14. Then, the cylinder 15 can be removed, and the moisture-absorbing sponges 16 inside the cylinder 15 can be centrally processed.

[0036] Specifically, the hot air circulation mechanism also includes a deflector plate 3, a blower 5, an exhaust pipe 1 8, an exhaust pipe 2 9, and a heating wire 20. The deflector plate 3 is fixedly installed inside the dryer box 1. The exhaust pipe 1 8 is fixedly connected to the blower 5. The blower 5 is fixedly connected to the main pipe 6. The exhaust pipe 2 9 is fixedly installed on the dryer box 1. A connecting cover 10 is fixedly fitted on the outside of both the exhaust pipe 1 8 and the exhaust pipe 2 9. The cylinder 15 is in sealed contact with the connecting cover 10. The heating wire 20 is fixedly installed inside the exhaust pipe 1 8.

[0037] Through the hot air circulation mechanism described above, the air inside the exhaust pipe 8 can be heated by the heating wire 20, and the heated air inside the dryer box 1 can be extracted and reused through the exhaust pipe 9. This is more energy-efficient and achieves hot air circulation.

[0038] Specifically, a temperature sensor is fixedly installed on the top rear side of the drying chamber 1. The detection end of the temperature sensor is connected to the inside of the drying chamber 1. A stabilizing bracket 2 is fixedly installed at the bottom of the drying chamber 1, and a controller is fixedly installed on the top of the stabilizing bracket 2. It should be noted that the temperature sensor monitors the temperature inside the drying chamber 1. When the temperature is lower than the set value, the controller causes the heating wire 20 to work to heat the chamber until the temperature reaches the set temperature range.

[0039] Specifically, a feeding pipe 4 is fixedly installed on the top of the drying chamber 1, a discharge pipe is fixedly installed at the bottom of the drying chamber 1, and there are multiple air supply pipes 7, which are evenly spaced to facilitate feeding and discharging.

[0040] Specifically, a sealing gasket is embedded at the end of the connecting cover 10, and the cylinder 15 is in sealing contact with the sealing gasket. It should be noted that this ensures the sealing of the connection.

[0041] Specifically, the rotating head 12 has multiple slots 13, and the insertion rod 14 is engaged with the slots 13. The connecting column 11 has multiple positioning grooves 18, and the positioning element 17 is engaged with the positioning grooves 18. The rotating head 12 has multiple moving holes, and the positioning element 17 is slidably installed in the moving holes. The insertion rod 14 has an insertion hole, and the positioning element 17 is engaged with the insertion hole. It should be noted that the insertion rod 14 and the rotating head 12 can be limited.

[0042] Working principle:

[0043] S1: The sodium carboxymethyl cellulose material to be dried enters the dryer chamber 1 through the feeding pipe 4 at the top of the dryer chamber 1. The blower 5 sends air into the exhaust pipe 8. The heating wire 20 in the exhaust pipe 8 heats the air. The hot air is evenly sent into the dryer chamber 1 through the main pipe 6 and multiple equally spaced air supply pipes 7. The guide plate 3 fixed inside the chamber guides the material to flow downwards in sequence. The hot air dries the material evenly during the material flow. At the same time, the exhaust pipe 9 extracts the hot air in the chamber and sends it back to the front end of the circulation system. It mixes with the newly entered air in the exhaust pipe 8 and reuses it to realize hot air circulation and improve energy utilization efficiency.

[0044] S2: When a moisture-absorbing sponge 16 has been used for a period of time, its moisture absorption capacity decreases. At this time, the positioning part 17 can be pulled. The positioning part 17 overcomes the tension of the spring 19 and moves out of the positioning groove 18 on the connecting column 11, so that the rotating head 12 is no longer limited by the positioning part 17. Rotating the rotating head 12 can rotate an adjacent cylinder 15 containing a new moisture-absorbing sponge 16 to the working position. Then, the positioning part 17 is released. Under the action of the spring 19, the positioning part 17 is re-engaged into the positioning groove 18, limiting the rotating head 12 and completing the switching of the moisture-absorbing sponge. When multiple moisture-absorbing sponges 16 have been used, the positioning part 17 can be pulled again to completely remove it from the insertion hole of the insertion rod 14, and then the cylinder 15 can be removed to centrally dry the moisture-absorbing sponges 16 inside for subsequent recycling.

[0045] S3: The temperature sensor on the top rear side of the dryer chamber 1 monitors the internal temperature of the chamber in real time and transmits the temperature signal to the controller on the top of the stabilizing bracket 2. When the temperature sensor detects that the internal temperature of the chamber is lower than the preset value of the controller, the controller issues a command to make the heating wire 20 work to heat the air in the exhaust pipe 8 and increase the internal temperature of the chamber. When the temperature reaches the set temperature range, the controller controls the heating wire 20 to stop heating or adjust the heating power to keep the internal temperature of the dryer chamber 1 stable, ensuring that the drying process is carried out under suitable temperature conditions, ensuring the drying effect while achieving energy-saving control. The moisture generated during the drying process will flow with the air. When the air containing moisture passes through the sealed contact part between the connecting cover 10 and the cylinder 15, the moisture-absorbing sponge 16 fixed inside the cylinder 15 absorbs the moisture, thereby reducing the humidity inside the chamber and ensuring the drying effect.

Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model.
