DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figure 1-5 As shown, a rotary cooling device for fertilizer production includes: a box body 1, the interior of the box body 1 is hollow, and a rotary drum 2 is rotatably arranged inside the box body 1, both ends of the rotary drum 2 extend to the outside of the box body 1, and the side wall of the box body 1 is provided with a socket for accommodating the rotary drum 2, and a feed hopper 3 is fixed on the outside of the box body 1 and at a position corresponding to the feed end of the rotary drum 2, and the fertilizer is introduced into the rotary drum 2 through the feed hopper 3, and a support plate is symmetrically fixed at the bottom end of the box body 1.

[0023] A limit ring is symmetrically fixed on the outer side of the rotating drum 2. The limit ring is annular. An annular groove is opened on the side wall of the box body 1 at the position corresponding to the limit ring. The annular groove is connected to the socket. The limit ring is slidably connected in the annular groove, so that the rotating drum 2 can rotate.

[0024] A driven gear ring 7 is fixedly sleeved on the outer side of the rotating drum 2, a motor 5 is fixed on the top of the box body 1, and the output end of the motor 5 is fixedly connected to a driving gear 6, which is meshed and connected with the driven gear ring 7. A plurality of curved guide plates are fixedly provided inside the rotating drum 2. The working principle of the curved guide plates inside the rotating drum 2 is mainly to guide the flow of fertilizer through their curved shape and rotational motion. The curved guide plates are prior art disclosed in the comparative documents and will not be elaborated on in detail.

[0025] The motor 5 is started, and the output end of the motor 5 drives the driving gear 6 to rotate. The driving gear 6 drives the rotary drum 2 to rotate by meshing with the driven gear ring 7. The fertilizer is introduced into the rotary drum 2 through the feed hopper 3. The fertilizer is guided by the rotating curved guide plate from the feed end to the discharge end of the rotary drum 2. During the guiding process, the fertilizer is in full contact with the rotary drum 2 to achieve heat conduction. The spray mechanism is used to spray coolant onto the surface of the rotary drum 2 to achieve heat exchange.

[0026] A spray mechanism is provided inside the box body 1, and the spray mechanism includes a water spray pipe 12 fixed to the inner wall of the upper end of the box body 1, and a plurality of nozzles are installed at the lower end of the water spray pipe 12. Water is supplied to the spray mechanism through a water supply mechanism. When in use, the nozzle at the lower end of the water spray pipe 12 is turned on, and the coolant inside the water spray pipe 12 is sprayed onto the surface of the rotary drum 2 through the plurality of nozzles.

[0027] A water supply mechanism is provided on the outside of the housing 1 for supplying coolant to the water spray pipe 12. The water supply mechanism comprises a water pump 4 fixed to the top of the housing 1 and a cooling box 8 fixed to the bottom of the housing 1. The pumping end of the water pump 4 is connected to a pumping pipe, which passes through the cooling box body 81 and communicates with the curved pipe 14. The discharge end of the water pump 4 is connected to a drain pipe, which communicates with the water spray pipe 12. When the water pump 4 is started, it discharges the coolant in the curved pipe 14 into the drain pipe and then the water spray pipe 12 through the pumping pipe, allowing the coolant to flow into the water spray pipe 12.

[0028] The cooling box 8 includes a cooling box body 81 and a connecting cover 83. The front end of the cooling box body 81 is open, and the connecting cover 83 is installed at the front end opening of the cooling box body 81. This design allows the cooling box body 81 to be easily opened.

[0029] As for how the connecting cover 83 is installed at the front end of the cooling box body 81: a plurality of fixing grooves 82 are provided at the front end of the cooling box body 81, and a fixing block is provided on the back side of the connecting cover 83 and at the position corresponding to each fixing groove 82. The connecting cover 83 can be fixed to the front end opening of the cooling box body 81 by engaging the fixing block with the fixing groove 82.

[0030] A curved tube 14 is fixedly installed inside the cooling box body 81. The end of the curved tube 14, away from the water extraction pipe, is connected to a bellows 10. The top of the bellows 10 is connected to a water collecting hopper 13, which is detachably mounted inside the cooling box body 81. The heated water falls to the bottom of the cooling box body 1 and is then directed into the curved tube 14 through the water collecting hopper 13 and the bellows 10.

[0031] The cooling box body 81 is connected to the box body 1, and the shape of the connection between the cooling box body 81 and the box body 1 is adapted to the water collecting bucket 13. A notch 84 is provided on the side wall of the cooling box body 81, and a first screw 11 is fixed to the outside of the water collecting bucket 13. The first screw 11 passes through the notch 84 and extends to the outside of the cooling box body 81. A nut 18 is threadedly connected to the first screw 11, and the nut 18 is located outside the cooling box body 81. By tightening the nut 18, the nut 18 is made to fit tightly against the outer wall of the cooling box body 81, thereby fixing the water collecting bucket 13.

[0032] To further secure the water collecting hopper 13, a fixing plate 17 is fixed to the inner wall of the upper end of the cooling box body 81. A second screw 16 is threadedly connected to the fixing plate 17. The second screw 16 passes through the fixing plate 17 and is rotatably connected to a contact plate 15. The shape of the contact plate 15 is adapted to the water collecting hopper 13. By rotating the second screw 16, the second screw 16 drives the contact plate 15 toward the water collecting hopper 13 until the contact plate 15 is tightly attached to the outside of the water collecting hopper 13, thereby further securing the water collecting hopper 13.

[0033] It should be noted that the present invention is also provided with a guide mechanism (not shown in the figure) for guiding the paste plate 15. The guide mechanism can be set as a guide rod, guide groove, etc. in the prior art, which only needs to achieve the guiding action of the paste plate 15.

[0034] A filter is installed inside the water collecting bucket 13 to filter the coolant to prevent impurities from clogging the pipeline.

[0035] A plurality of fans 9 are installed on the connection cover 83. When the fans 9 are turned on, they blow air to the curved tube 14 to dissipate heat, so that the heat carried by the coolant inside the curved tube 14 is dissipated, and the cooled coolant can be sprayed through circulation.

[0036] Working principle:

[0037] When the filter needs to be cleaned, use force to separate the fixing block on the back of the connecting cover 83 from the fixing groove 82, so that the connecting cover 83 is separated from the cooling box body 81, loosen the nut 18, and then turn the second screw 16. The second screw 16 drives the plate 15 to gradually move away from the water collecting bucket 13, so that the water collecting bucket 13 can be moved. Pull the water collecting bucket 13 down to the bottom of the cooling box body 81. The staff can see the installation structure of the filter, which is convenient for removing the filter from the inside of the water collecting bucket 13 for cleaning.

[0038] The above embodiments are only used to illustrate the technical method of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
