Abstract
Description
Technical Field

[0002] The air energy heat pump drying tower is a device that uses air energy heat pump technology to dry materials. It is an efficient and energy-saving drying equipment. Its working principle is based on the reverse Carnot principle. The refrigerant in the heat pump passes through the condenser in the evaporative heat exchanger at low temperature, absorbs heat energy in the indoor air, thereby increasing the temperature of the refrigerant and turning it into a gaseous state. The gaseous refrigerant is then compressed by the compressor to increase its temperature and pressure, and then the gas in the drying tower is heated through the heat exchanger to evaporate the moisture in the material in the form of hot air. The evaporated wet steam is discharged through the dehumidification system to achieve the purpose of drying the material. When using the drying tower, it is necessary to use conveying equipment to transport the grains to the interior of the drying tower. The conveying equipment of the traditional drying tower does not have a pre-screening device when transporting grains, and the grains are easily mixed with debris, resulting in reduced grain drying quality.

[0025] For examples, see Figure 1-5 , the utility model provides a technical solution:
[0026] A conveying device for an air energy heat pump drying tower comprises a base 1, a drying tower 2 is installed at one end of the top of the base 1, a screening box 3 is installed at one end of the top of the base 1 away from the drying tower 2, a box door 301 is installed on the wider side surface of the outside of the screening box 3, a feed hopper 4 is installed on the top of the screening box 3, an inclined plate 5 is installed on the inner bottom of the screening box 3, guide plates 6 are symmetrically installed on the narrower side walls inside the screening box 3, a slide bar 7 is installed between the two ends of the narrower side walls inside the screening box 3 and below the two guide plates 6, a sieve plate 8 is installed on the outside of the slide bar 7, a return spring 9 is installed on the narrower side surface of the outside of the sieve plate 8, a drive motor 10 is installed on the narrower side wall inside the screening box 3, and an elliptical block 11 is installed on the output shaft of the drive motor 10;
[0027] A storage box 12 is installed at the bottom edge of the wider outer side of the screening box 3, a conveying pipe 13 is installed on the top of the storage box 12, a rotating shaft 14 is installed on the inner top of the conveying pipe 13, a spiral blade 15 is installed on the outer ring surface of the rotating shaft 14, a conveying motor 16 is installed on the top of the conveying pipe 13, and a connecting pipe 17 is installed at one end of the top of the outer ring surface of the conveying pipe 13.
[0028] Specifically, refer to Figure 3 , Figure 4 and Figure 5 The inner parts of both ends of the sieve plate 8 are slidably connected with the outer annular surfaces of the two slide bars 7, and the two ends of the reset spring 9 are fixedly connected with the sieve plate 8 and the inner side walls of the screening box 3, thereby ensuring that the elliptical block 11 is driven to rotate by the driving motor 10. The elliptical block 11 rotates to squeeze the sieve plate 8 to slide on the outside of the two slide bars 7 and squeeze the reset spring 9 at the same time. When the longer side of the elliptical block 11 is squeezed, the restriction of the reset spring 9 is released, thereby driving the sieve plate 8 to reset. The elliptical block 11 circulates and rotates, thereby driving the sieve plate 8 to continue to reciprocate on the outside of the two slide bars 7, thereby avoiding accumulation of debris on the top of the sieve plate 8 and ensuring the screening effect.
[0029] Furthermore, a discharge port is provided at the inner bottom of the screening box 3 and flush with one side of the lower end of the inclined plate 5, and the discharge port on the screening box 3 is communicated with the interior of the storage box 12, thereby ensuring that the screened grains slide into the interior of the storage box 12 through the inclined plate 5 under the action of gravity.
[0030] Furthermore, the top of the sieve plate 8 is slidably connected and fits with the bottom of the two guide plates 6, and the two ends of the sieve plate 8 will not be separated from the bottom of the two guide plates 6, thereby preventing the grains on the top of the sieve plate 8 from falling from the gap between the sieve plate 8 and the two guide plates 6 to the inner bottom of the screening box 3, resulting in reduced screening quality.
[0031] Furthermore, the conveying pipe 13 is connected to the interior of the storage box 12, and the connecting pipe 17 is connected to the pipe inside the drying tower 2 away from the conveying pipe 13, thereby ensuring that the screened grains can enter the interior of the drying tower 2 through the conveying pipe 13 and the connecting pipe 17 for drying after arriving at the storage box 12.
[0032] For details, please refer to Figure 2 The bottom end of the rotating shaft 14 is rotatably connected to the inner bottom of the storage box 12, and the top end of the rotating shaft 14 passes through the conveying pipe 13 and is connected to the output shaft of the conveying motor 16, thereby ensuring that the rotating shaft 14 is driven by the conveying motor 16 to rotate and drive the spiral blade 15 to rotate, so that the screened grains in the storage box 12 are transported to the top of the conveying pipe 13 through the spiral blade 15, and then enter the interior of the drying tower 2 through the connecting pipe 17.
[0033] The working process of the utility model: using the conveying equipment of the air energy heat pump drying tower designed by the present invention, when the grains need to enter the drying tower for drying, firstly, the grains are put into the inside of the screening box 3 from the feed hopper 4 through an external machine, and the grains will fall onto the sieve plate 8, and the elliptical block 11 is driven to rotate by the driving motor 10. The elliptical block 11 rotates to squeeze the sieve plate 8 to slide on the outside of the two sliding rods 7 and squeeze the reset spring 9 at the same time. After the longer side of the elliptical block 11 is squeezed, the restriction of the reset spring 9 is released, thereby driving the sieve plate 8 to reset. The elliptical block 11 circulates and rotates to drive the sieve plate 8 to continuously reciprocate on the outside of the two sliding rods 7, thereby avoiding the accumulation of debris on the top of the sieve plate 8 and ensuring the screening effect. The two ends of the sieve plate 8 will not be separated from the bottom of the two guide plates 6, thereby preventing the grains on the top of the sieve plate 8 from falling from the gap between the sieve plate 8 and the two guide plates 6 to the inner bottom of the screening box 3, resulting in reduced screening quality. The screened grains slide into the storage box 12 through the inclined plate 5 under the action of gravity, and the spiral blades 15 are driven by the conveying motor 16 to rotate the rotating shaft 14, so that the screened grains in the storage box 12 are conveyed to the top of the conveying pipe 13 through the spiral blades 15, and then enter the drying tower 2 through the connecting pipe 17. The residual debris screened on the top of the sieve plate 8 can be cleared by opening the box door 301, thereby ensuring the quality of grain drying and preventing the entry of debris and reducing the quality of grain drying.
[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
