Description

Technical Field

[0001] The utility model belongs to the technical field of drying equipment, and specifically relates to a heat storage type drying device for solid heat storage materials. Background Technique

[0002] Heat pump drying technology has many advantages, so it has been widely applied and studied in the drying and processing of agricultural and sideline products; however, in China, heat pump drying technology has not been widely used in the drying and processing of agricultural and sideline products. The key reason lies in the defects of the heat pump drying device itself; traditional heat pump drying devices are often designed as closed structures, that is, in a heat pump drying system, the circulating air serves as both a drying medium and a cooling medium for the condenser of the refrigeration system. The circulating air cools and dehumidifies through the evaporator and heats up through the condenser. Therefore, when the ambient temperature is relatively high, especially in summer, the temperature rise of the circulating air causes the condensation pressure of the condenser to increase and the exhaust temperature of the refrigeration compressor to rise, resulting in frequent operation of the high-pressure protection or overheat protection of the refrigeration compressor, and the heat pump drying device cannot work properly, thus limiting the application of the heat pump drying device in the drying and processing of agricultural and sideline products.

[0003] Chinese Patent with Publication No. CN203349611U discloses a heat storage and cold storage type heat pump drying device. Through the heat storage effect of the heat storage agent in the high-temperature intermediate heat exchanger and setting the maximum temperature of the heat storage agent, when the ambient temperature is relatively high, the temperature of the circulating air rises, and the temperature of the heat storage agent rises to the limit temperature, causing the refrigeration compressor to stop. At this time, the heat storage agent can continue to provide heat to the circulating air through the heat carrier system until the temperature of the heat storage agent drops to the range set by the temperature controller, and the refrigeration compressor restarts and provides heat to the heat storage agent again. However, the heat charging process of the solid heat storage material may be relatively slow and requires a long time to reach the required temperature. This device cannot accelerate the heat charging process, thus affecting the production efficiency.

[0004] In view of this, the present utility model is specifically proposed. Summary of the Invention

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0028] Now the present utility model will be further described in detail with reference to the accompanying drawings.

A drying chamber 6 and a storage chamber 7 are arranged inside the main body 1, and a sealing door 2 is installed at the opening of the drying chamber 6. Closing the sealing door 2 reduces and ensures the loss of hot gas inside the drying chamber 6. A gear 11 and a connecting rod 12 are installed inside the sealing door 2. The gear 11 is meshed and connected with the connecting rod 12. A bolt 13 is installed at the top of the connecting rod 12. Moving the bolt 13 by driving the connecting rod 12 can lock or unlock the door, improving the stability and sealing performance of the door. A shunt box 9 is embedded in the left side wall of the drying chamber 6. An adjusting plate 8 is arranged inside the shunt box 9. The adjusting plate 8 is connected with a handle 5. Changing the position of the adjusting plate 8 can adjust the shunt direction and flow rate.

[0030] In this embodiment, the connecting pipe 4 penetrates through the side wall of the storage chamber 7 and is fixedly connected with the shunt box 9. The hot gas enters the drying chamber 6 through the shunt box 9. A fixing rod is arranged in the connecting pipe 4. The rotating shaft 16 penetrates through the fixing rod and is rotatably connected with the fixing rod. The fixing rod plays a role in supporting and stabilizing the rotating shaft 16, so that the rotating shaft 16 can maintain stability during rotation, ensuring the normal operation of the fan 14. The connecting shaft 15 penetrates through the side wall of the connecting pipe 4 and is fixedly connected with the motor 10. The motor 10 is fixedly connected with the inner wall of the drying chamber 6 through a fixing base. And heat dissipation holes are arranged at the front end of the drying chamber 6. The heat dissipation holes can reduce the heat generated by the operation of the motor 10.

[0031] By starting the motor 10, the motor 10 drives the connecting shaft 15 to rotate. The connecting shaft 15 drives the rotating shaft 16 to rotate through the worm gear 17 and the worm 18, and then drives the fan 14 to rotate. When the hot air flow enters the connecting pipe 4, the rotation of the fan 14 can increase the flow rate of the hot air flow, thereby enhancing the heat transfer process, so that the fixed heat storage material placed in the drying chamber 6 can contact the hot air flow more frequently, and then the heat charging process is accelerated.

[0032] In this embodiment, a plurality of flow dividing grooves are provided in the flow dividing box 9, which can divide the hot air flow entering the flow dividing box 9 into multiple independent channels for distribution. And an adjusting plate 8 is provided in each flow dividing groove. By adjusting these adjusting plates 8, the flow rate and flow direction in each flow dividing groove can be accurately controlled. The handle 5 sequentially penetrates through the front end of the left side wall of the drying chamber 6 and the front end of the flow dividing box 9 and is fixedly connected to the adjusting rod. An operator can control the adjusting plate 8 from outside the drying chamber 6 by operating the handle 5. The top and bottom ends of the adjusting plate 8 are both arc-shaped, and the top and bottom ends are respectively abutted against the inner top wall and inner bottom wall of the flow dividing groove, making the adjusting plate 8 move more smoothly in the flow dividing groove, reducing resistance. At the same time, being tightly abutted against the inner wall of the flow dividing groove can ensure good sealing performance and prevent air flow or medium leakage, so as to more effectively realize the functions of flow division and adjustment.

[0033] After the hot air flow passes through the inside of the flow dividing box 9, the flow dividing grooves inside the flow dividing box 9 evenly distribute the hot air flow, so that the hot air flow can enter the drying chamber 6 evenly, and the solid heat storage material in the drying chamber 6 can be evenly and fully heated. An operator can drive the adjusting plate 8 to rotate by rotating the handle 5, so as to adjust the opening flow rate of the flow dividing groove, avoid the hot air flow not entering the inside of the drying chamber 6 evenly, and by adjusting the direction of the adjusting plate 8, the direction of the hot air flow entering the drying chamber 6 can be changed, so as to more conveniently heat the solid heat storage material.

[0034] In this embodiment, jacks are provided at the corresponding positions of the plug pin 13 and the opening end of the drying chamber 6. When the plug pin 13 is inserted into the jacks, the sealing door 2 can be firmly locked at the opening of the drying chamber 6 to ensure the sealing performance of the drying chamber 6. The plug pin 13 penetrates through the inside of the sealing door 2 and is slidably connected to the inside of the sealing door 2. The plug pin 13 can move flexibly inside the sealing door 2 to realize the actions of inserting into and pulling out of the jacks. The gear 11 is rotatably connected to the inside of the sealing door 2, and the connecting rod 12 is slidably connected to the inside of the sealing door 2, ensuring that the connecting rod 12 can slide stably along a specific direction, so as to drive the plug pin 13 to perform locking or unlocking operations. A sealing rubber ring is installed on the outer frame of the sealing door 2. The sealing rubber ring can fill the gap between the sealing door 2 and the opening of the drying chamber 6 when the sealing door 2 is closed, further enhancing the sealing effect and preventing the heat in the drying chamber 6 from leaking, and accelerating the heating of the solid heat storage material.

[0035] First, the braking box 3 generates hot air flow, and the hot air flow enters the inside of the main body 1 through the connecting pipe 4. After the motor 10 is started, it drives the connecting shaft 15 to rotate. Through the rotation of the worm 18 and the worm gear 17 by the connecting shaft 15, the rotating shaft 16 rotates, and then drives the fan 14 to operate. The rotation of the fan 14 increases the flow rate of the hot air flow in the connecting pipe 4 and enhances the heat transfer process;

[0036] The hot air flow enters the shunt box 9 after passing through the connecting pipe 4. Multiple shunt grooves in the shunt box 9 divide the hot air flow into multiple independent channels. By operating the handle 5 to drive the adjusting plate 8, the flow rate and flow direction in each shunt groove can be precisely controlled. The shunted hot air flow evenly enters the drying chamber 6, enabling the solid heat storage material in the drying chamber 6 to be evenly and fully heated. The operator can also change the direction of the hot air flow entering the drying chamber 6 by rotating the handle 5, making it more convenient to heat the solid heat storage material;

[0037] At the opening of the drying chamber 6, the sealing door 2 is used to close the drying chamber 6. By rotating the gear 11 inside the sealing door 2, the engaged connecting rod 12 is driven to slide, so that the bolt 13 at the top of the connecting rod 12 is inserted into or pulled out of the corresponding jack at the opening end of the drying chamber 6, realizing the locking or unlocking of the sealing door 2. The sealing rubber ring at the outer frame of the sealing door 2 fills the gap when the sealing door 2 is closed, further enhancing the sealing effect, reducing the heat leakage in the drying chamber 6, and accelerating the heating of the solid heat storage material. In summary, through the coordinated work of each component, the entire device realizes the efficient transportation of the hot air flow, uniform distribution, and good sealing of the drying chamber 6, thereby accelerating the heating process of the solid heat storage material.
