As shown in fig. 1 to 5, the present embodiment provides a heat pump grain dryer including: frame 1, compressor 2, evaporimeter 3, evaporation fan 4, water storage tank 5, water pump 6 and spray assembly 7, compressor 2 install in the frame 1, the air intake has been seted up to the side of frame 1, evaporimeter 3 install in the inboard of air intake, evaporation fan 4 install in the top of frame 1, water storage tank 5 install in on the base in the frame 1, spray assembly 7 with water storage tank 5 passes through the pipe connection, spray assembly 7 set up in the outside of air intake and with the evaporimeter 3 is corresponding, water pump 6 install in on the water storage tank 5.

Based on the above scheme, the work flow of the unit is that the compressor 2 is communicated with the evaporator 3 through a pipeline, the refrigerant in the compressor 2 enters the evaporator 3 through the pipeline, the air in the environment enters the unit from the air inlet, after heat exchange is carried out at the evaporator 3, the air is discharged out of the unit under the power drive of the evaporation fan 4, and the position of the evaporation fan 4 is equal to the air outlet of the unit. Before the air gets into the heat transfer of evaporimeter 3 from the air intake, can spray the filtration through spray assembly 7 earlier, spray assembly 7 spun water smoke can form the cascade barrier, after this barrier of air process, pollutants such as dust in the air can be filtered by the cascade barrier, the air after the filtration can become cleaner relatively, spray assembly 7 has replaced traditional filter screen, spray assembly 7 is better than the filter screen moreover, its filter effect is better, because the dust can not adhere to spray assembly 7, the abluent process has been reduced, but also can use spray assembly 7 to spray the air inlet side surface of evaporimeter 3, make the dust of adhering to at evaporimeter 3 surface by effectively flushing, guarantee the heat transfer effect of evaporimeter 3. In this scheme, the main function of spray assembly 7 realizes in two aspects, adopts the mode of spraying to filter the dust on the one hand, and on the other hand can effectively wash evaporimeter 3, and this makes the steady operation of whole unit obtain effective guarantee, has still reduced the cost of manufacture of unit.

Preferably, the spray assembly 7 includes a spray main 701, a plurality of spray branch pipes 702, a fixing seat 703, a buckle 704, a fixing piece 705 and a plurality of spray nozzles 706, the middle position of the frame 1 is provided with a stand column for fixing the evaporator 3, the fixing seat 703 is fixedly mounted on the stand column, particularly welded on the stand column, the buckle 704 is convexly arranged on one side of the fixing seat 703 deviating from the direction of the stand column, a clamping position capable of being clamped with the spray main 701 is naturally formed in the buckle 704, so that the spray main 701 can be clamped with the buckle 704, the spray main 701 is correspondingly and vertically arranged on the stand column and is positioned on the outer side of the air inlet, each spray branch pipe 702 is respectively connected with two sides of the spray main 701 and is communicated with the spray main 701, and the spray branch pipes 702 on the same side are uniformly arranged at intervals in the vertical direction.

Since the spray branch pipes 702 are separately provided at both sides of the spray main pipe 701, it is understood that only one spray branch pipe 702 is provided on the same horizontal line, and the middle position of the spray branch pipe 702 is communicated with the spray main pipe 701 and extends toward both sides of the spray main pipe 701, in this case, both ends of the spray branch pipe 702 are not fixed, so that the fixing members 705 are provided at both ends of the frame 1 in order to ensure stable installation of the spray branch pipe 702, and the spray branch pipe 702 is further fixed by being connected to the ends of the spray branch pipe 702 through the fixing members 705.

In addition, the two spraying branch pipes 702 may be respectively connected to two sides of the spraying main pipe 701, so that more heat pump grain dryers of different types may be applied, for example, when the heat pump grain dryer has two air channels, two evaporators 3 and two corresponding evaporating fans 4 are respectively arranged, the heat pump grain dryer can be understood to have two heat pump systems running relatively independently at this time, the two spraying branch pipes 702 on two sides of the spraying main pipe 701 respectively correspond to two heat pump systems, the two spraying branch pipes 702 are arranged at this time, when the unit only runs one heat pump system, the spraying branch pipes 702 on the corresponding side can be independently started to perform spraying action, and the practical application is more intelligent.

In order to achieve a better water mist spraying effect, each spraying nozzle 706 is arranged on the spraying branch pipe 702 at intervals and sprays towards the direction of the evaporator 3, the spraying nozzles 706 are arranged in a mode of ensuring that the water mist sprayed by all the spraying nozzles 706 can cover the whole air inlet and the whole evaporator 3 after crossing, and thus an effective filtering and cleaning effect can be achieved.

The spray nozzles 706 are preferably fan-shaped spray nozzles 706 for better spray results.

When the spraying branch pipes 702 are arranged, the adjustment is needed according to the area of the evaporator 3 of the unit, and the positions of the spraying branch pipes 702 and the spraying nozzles 706 are required to be distributed because the spraying positions of the fan-shaped spraying nozzles 706 are limited, and the spraying nozzles 706 of the first layer and the second layer of the spraying branch pipes 702 are required to be distributed in a staggered mode, otherwise, dead areas exist in part of the areas and cannot be sprayed, the first layer can be understood as the spraying branch pipe 702 at the uppermost position, the second layer is the spraying branch pipe 702 adjacent to the lower position, and the spraying nozzles 706 installed on the two adjacent spraying branch pipes 702 are required to be arranged in a staggered mode in general.

Specifically, the horizontal spacing between the spray nozzles 706 on the same spray manifold 702 is between 300mm and 350mm, and the vertical spacing between the spray manifolds 702 is between 320mm and 360 mm. The specific interval is required to be determined according to the specific area of the evaporator 3, when the horizontal interval of the spray nozzles 706 is 300mm and the vertical interval of the spray branch pipes 702 is 320mm, which is equivalent to the minimum spray area, the spray of water mist is relatively dense, and the method is suitable for the condition that the area of the evaporator 3 is not large; when the horizontal spacing of the spray nozzles 706 is 350mm and the vertical spacing of the spray branches 702 is 360mm, the spray area is relatively maximum, which is suitable for larger units of evaporator 3.

It should be noted that, in the above-described manner of determining the interval, when the vertical interval of the shower branch pipes 702 is 360mm, the interval corresponding to the shower branch pipes 702 is maximized, so that the shower branch pipes 702 adjacent in the up-down direction are farthest apart, and when considering the size of the shower area of the shower nozzle 706, it is preferable to set the horizontal interval of the shower nozzle 706 to 300mm, the interval to the minimum, and the shower coverage area to the maximum, so as to ensure that the evaporator 3 can be fully covered.

In some embodiments, a water receiving disc 8 is arranged below the evaporator 3, a water collecting port 9 is arranged at the bottom of the water receiving disc 8, water on the water receiving disc 8 is collected at the water collecting port 9, and then the water collecting port 9 and the water storage tank 5 are connected through a water collecting pipe to form a circulation loop.

Optionally, a water supplementing port is further provided on the water storage tank 5, and the water supplementing port is connected to an external water supplementing device through a pipeline, and water is supplemented into the water storage tank 5 through the water supplementing port by the external water supplementing device, so that water in the water storage tank 5 is guaranteed to meet the spraying requirement.

Further, the evaporator 3 is a fin heat exchanger.

In the actual use process, before the machine set is started, whether tap water circulates through a pipeline connected to a water supplementing port or not is checked, when the machine set is started, the water storage tank 5 is fully filled with the tap water through the water supplementing port, the water pump 6 starts to act, the water of the water storage tank 5 is conveyed to the fan-shaped spray nozzles 706 from the spray main pipe 701 to the spray branch pipe 702 at high pressure through the water pump 6, the water is uniformly sprayed to fins of the evaporator 3 through the fan-shaped spray nozzles 706, dust stuck to the fins is washed to the water receiving disc 8 through the high-pressure water mist, and then flows back to the water storage tank 5 through the water collecting port 9 at the bottom of the water receiving disc 8 to form circulation through a water return pipe. Because the unit runs for a long time, the water in the water storage tank 5 is always recycled and becomes more turbid, a water outlet is formed in the water storage tank 5, when the set accumulated time is reached, the water outlet is opened to drain turbid water, and then the water supplementing port is reused to supplement the water in the water storage tank 5.
