Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In order to improve the material drying efficiency of the existing biological fertilizer machine, the invention provides a dual-mode heating and drying method of a biological degradation fertilizer machine, which is shown in figure 1 and comprises top hot air drying and bottom circulating oil heat conduction.

The top hot air drying mode is as shown in fig. 2, external air is introduced by a fan 11, heated by a hot air heater 12, enters the bin body 3 through a hot air inlet pipe 13, flows over the material 31, and then is discharged through a hot air outlet pipe 14. The top hot air drying mainly takes away water vapor through top hot air, the saturated water content of hot air is increased rapidly along with the increase of temperature, and the capacity of carrying water vapor is correspondingly increased.

The top hot air supply component mainly comprises a fan 11, a hot air heater 12, a hot air inlet pipe 13 and a hot air outlet pipe 14. Hot air flows to the other side from one side of the upper end of the bin body 3, namely, a hot air inlet pipe 13 is positioned on one side of the upper end of the bin body 3, a hot air outlet pipe 14 is positioned on the other side of the upper end of the bin body 3, and after the hot air is fully contacted with the steam in the bin body 3, the steam is taken out of the bin body 3.

In order to better recover the heat of the hot air sent out of the bin body 3, a heat exchanger 15 can be additionally arranged between the fan 11 and the hot air heater 12, one side of the heat exchanger 15 is positioned between the fan 11 and the hot air heater 12, the other side of the heat exchanger 15 is connected with a hot air inlet pipe 13, and the discharged hot air is used for preheating the fresh air entering the bin body 3. Meanwhile, in order to reduce the dust and harmful gas of the materials in the bin body 3 brought out when the hot air is discharged, a waste gas treatment tower 16 is arranged at the hot air outlet.

The heat conduction mode of the bottom circulating oil is as shown in fig. 3, the oil is guided by a heat conduction oil pump 21, heated by a heat conduction oil heater 22, enters the bin body 3 through a heat conduction oil supply pipe 23, passes through a synergistic oil circuit partition plate 24 positioned below the material 31, enters a heat conduction oil return pipe 25, is filtered by a heat conduction oil filter 26, and then flows back to the heat oil pump 21.

The bottom circulating oil heat conduction assembly mainly comprises a heat conduction oil pump 21, a heat conduction oil heater 22, a heat conduction oil supply pipe 23, a synergistic oil way partition plate 24, a heat conduction oil return pipe 25 and a heat conduction oil filter 26. Wherein, the bottom and the side of the bin body 3 are both provided with circulating heat conducting oil, and the materials 31 are indirectly heated through a heat conduction mode. In fig. 3, the right side of the bin body 3 is connected with a heat-conducting oil supply pipe 23, and the left side is connected with a heat-conducting oil return pipe 25.

As shown in fig. 4, the structure of the synergistic oil path partition plate 24 is that first, the bottom space of the bin body 3 is divided into a plurality of large spaces by the first partition plate 241 to form a large "S" shaped loop; a plurality of second partitions 242 are then inserted into each large space, forming a small "S" shaped loop in each large space. The arrangement of the synergistic oil circuit partition plate 24 fully increases the effective length of the oil circuit and increases the effective heat transfer.

The actual structure of the synergistic oil path partition plate 24 is as shown in fig. 5, an oil cavity is formed by a bin body tube plate 243 and an oil seal plate 244 at the bottom of the bin body 3, a first partition plate 241 perpendicular to the axial direction of the stirring rod is arranged in the oil cavity, the oil cavity is divided into a plurality of large spaces by the first partition plate 241, and each large space is communicated with an opening of the first partition plate 241; then, the second partition plates 242 are alternately arranged in a staggered manner in the left-right direction in each large space, and a small S-shaped loop is formed in each large space.

Because the bottom circulating oil is lost in the circulating process, a heat-conducting oil supplementing oil pipe 27 and an oil tank 28 can be arranged in the heat-conducting oil circuit, and an air pressure relief branch pipe 29 can be additionally arranged for exhausting and relieving pressure for the main pipeline. As shown in fig. 3, one end of the heat-conducting oil supply pipe 27 is connected to the heat-conducting oil return pipe 25, the other end is connected to the oil tank 28, the other side of the oil tank 28 is connected to the exhaust and pressure relief branch pipe 29, and the other side of the exhaust and pressure relief branch pipe 29 is connected between the heat-conducting oil pump 21 and the heat-conducting oil heater 22.
