Description

Technical Field

[0001] The utility model belongs to the technical field of fertilizer production, and particularly relates to a fertilizer drying device for energy conservation, emission reduction and clean production. Background Art

[0002] Fertilizer is the material basis for agricultural planting. Using fertilizer can improve the soil fertility for crop planting, make it more suitable for the growth of crops, and then achieve the effect of increasing the yield of crops. When producing fertilizer, it also needs to be dried. The wet fertilizer is dried by a dryer to make it more convenient for storage and transportation, and at the same time, its nutrient components are not reduced.

[0003] A Chinese patent application (or patent) with the publication number of CN221630268U discloses a fertilizer box that can dry fertilizer. Its technical solution includes: a box body and a storage frame. The storage frame is installed in the box body and is stacked. A heating plate is fixed on the inner side wall of the storage frame. The bottom of the storage frame is separated into a driving cavity and a purification cavity by a heat insulation plate. A driving motor for driving the storage frame to rotate is fixed in the driving cavity. An activated carbon filter element is installed in the purification cavity. A connecting pipe is installed between the upper side wall of the box body and the purification cavity. The utility model places the fertilizer into the multi-layer combined storage frame and rotates it to make it evenly heated in the box body to ensure consistent drying effect. At the same time, an air purification structure is set up to adsorb and purify the harmful gases generated during the drying process to ensure that the working environment is not polluted.

[0004] For the above-mentioned fertilizer box that can dry fertilizer, a purification cavity is provided in the box body. The purification cavity is communicated with the box body through a connecting pipe, and an activated carbon purification filter element is also provided inside the purification cavity. That is, the gas generated during the drying process is input into the purification cavity through the connecting pipe, and then this part of the gas is purified and filtered by the activated carbon filter element. The purification cavity is arranged at the bottom of the box body. At the same time, because the gas in the cavity will be heated during the drying process, and due to the principle that hot air rises, it is extremely difficult to enter the purification cavity at the bottom of the box body. Therefore, the efficiency and speed of purifying the gas are relatively slow. After using a fan for air extraction, it will also cause the problem of excessive consumption of electric power resources. In addition, it uses a plurality of disk-shaped storage frames stacked in parallel to carry the fertilizer to be dried, and uses a motor and a rotating rod to provide rotational power for the storage frame. This method will cause excessive pressure on the motor rotor of the motor, and at the same time, because the rotating shaft is arranged at the center of the storage frame, it will also cause the problem that the storage frame is difficult to take and place. Therefore, we provide a fertilizer drying device for energy conservation, emission reduction and clean production to solve the problems that appear above. Summary of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention. Embodiment 1

[0030] Please refer to Figures 1-5 , the present invention is a fertilizer drying device for energy conservation, emission reduction and clean production, including a lower outer cylinder 1. By using the outer cylinder cover 3 covered on its outer side, an openable and sealed chamber can be formed, and then the negative pressure fan 5, the air duct 6 and the purification component 4 can be used to purify the gas generated during the drying process.

[0031] Specifically, an outer cylinder cover 3 is rotatably provided on the rear side wall of the lower outer cylinder 1, and support seats 2 are also cooperatively provided on the bottom side walls at both ends of the lower outer cylinder 1. A negative pressure fan 5 is installed on the top of the outer cylinder cover 3. The air inlet of the negative pressure fan 5 passes through the outer cylinder cover 3 and communicates with its inner chamber, and the air outlet end of the negative pressure fan 5 is sleeved with an air duct 6.

[0032] Furthermore, a controller 301 is inlaid on the front outer wall of the outer cylinder cover 3, and an air outlet groove 302 is formed on the top of the outer cylinder cover 3. The air outlet groove 302 is opposite to the air inlet of the negative pressure fan 5, and a purification component 4 is also covered on the air outlet groove 302. The purification component 4 includes a purification box 401 covered on the air outlet groove 302, and a purification core 402 is inlaid inside the purification box 401.

At the same time, the other end of the air duct 6 also penetrates into the left side wall of the outer cylinder cover 3, and an electric heating grid plate 303 is inlaid on the outer cylinder cover 3 at this position.

[0033] The operation process of this embodiment is as follows: When in use, the negative pressure fan 5 can suck the gas in its inner chamber from the air outlet groove 302 in the outer cylinder cover 3 into the inside of the purification box 401, so that this part of the gas contacts with the purification core 402 and can be purified by the purification core 402. Only the purified gas will enter the inside of the negative pressure fan 5 and be input into its inner chamber from the side wall of the outer cylinder cover 3 through the air duct 6. And when the purified gas is input, this part of the purified gas flowing into the chamber will also be heated by the electric heating grid plate 303, thereby achieving the effect of heat circulation, reducing the waste of thermal resources, and achieving the effect of energy conservation and emission reduction. Embodiment 2

[0040] Further, the linkage shaft 903 extends out of the lower outer cylinder 1 to its outside. The second grooved pulley 804 is sleeved on one end of the linkage shaft 903 outside the lower outer cylinder 1, and the first grooved pulley 802 is arranged directly below the second grooved pulley 804. A machine frame 801a is fixedly installed on the outer side wall of the tail end of the driving motor 801, and the machine frame 801a is also fixedly connected to the outer side wall of the lower outer cylinder 1 through bolts.

[0041] The operation process of this embodiment is as follows: When in use, first open the outer cylinder cover 3 on the lower outer cylinder 1, and then open the inner cylinder cover plate 902 to open the inner cavity of the inner cylinder body 901, and then the fertilizer to be dried can be put into it. After the fertilizer is put in, close the inner cylinder cover plate 902 and the outer cylinder cover 3 in sequence, and then start the driving motor 801, which drives the inner cylinder assembly 9 to rotate through the first grooved pulley 802, the belt 803 and the second grooved pulley 804.
