Description

Continuous circulation dual-purpose dryer

Technical Field

The utility model relates to the field of grain drying, in particular to a continuous circulation dual-purpose dryer.

Background

The continuous process refers to a continuous process of feeding, drying, cooling, discharging and recycling grains in a drying device. The circulation refers to the process that grains pass through a continuous process in a drying device, and the continuous process is repeated one or more times when the drying requirement cannot be met.

The patent application number 2022227467455, entitled "an energy layering straight-through grain drying device", discloses a drying device, and it is provided with the cooling section, and the effect of setting the cooling section lies in that the grain after the stoving generally all has the temperature requirement, and the grain of direct warehouse entry after the stoving then is more strict to the stoving temperature requirement, and the grain temperature of drying through the stoving section is generally higher than this temperature, sets up the cooling section and is used for cooling for the grain.

Generally, the drying device can meet the drying requirements of various grains, and when the humidity of the grains is high, the drying efficiency can be improved by improving the drying heat supply of the drying section, so that the drying operation is completed in a continuous process; the grain discharging structure is used for discharging grains, and can control the running speed of grains in the drying device and control the drying operation to be completed in a continuous process under the state that the upper end and the lower end of each functional module are all in open connection in the drying device.

However, the grain is easy to burst under the condition of excessive heat drying, and under the condition of higher grain quality requirement, the drying heat supply needs to be reduced, and the requirement is difficult to meet in a continuous process. The drying section of the drying device is generally connected up and down by a plurality of drying sections, and when the upper end and the lower end of each functional module are in open connection state in the drying device, during grain drying operation, grains are possibly in a state of being in an ' dissatisfied bin ' in the drying device, the grains can be concentrated at the lower part of the drying device, partial drying sections are in failure ', and drying is finished only by the drying sections positioned at the lower part of the drying structure, and drying is difficult to finish in one continuous process.

The utility model comprises a continuous grain drying process and a circulating process of grain drying, and the circulating process can meet the requirements under the condition that the continuous grain drying process can not meet the drying requirements.

In the circulation process, when the grain does not reach the humidity requirement, the cooling section is unnecessary, and the cooling can have the anti-effect of 'cooling' on the grain, so that the 'cooling section' can be selected not to be started, and in order to further improve the drying efficiency, the cooling section adopts a cooling and drying switchable mode, so that the grain drying efficiency is improved.

What needs to be specifically stated is: the lifting mechanism 2, the grain discharging mechanism 15, the fan 3, the cold source 5, the heat source 4 and the valve 6 all adopt corresponding parts meeting the requirements in the prior art; the first valve 6a and the second valve 6b may be combined into one valve, and the valve may be combined into one valve when the valve has the function of switching off the heat source 4 while the heat source 5 is connected, and switching off the heat source 4 while the heat source 5 is connected.

Referring to fig. 1, in this embodiment, the upper and lower ends of the grain storage tower section 12, the drying tower section 131, and the cooling tower section 14 are all open. It should be noted that, when the upper and lower connection ends of the tower section are both in an open state, the whole drying tower 1 forms a continuous grain storage bin, and the running speed of the grain discharging mechanism 15 determines the running speed of grains in the drying tower 1; the heat supply of the drying section and the cooling capacity supply of the cooling section are adjustable, and the grain outlet can observe the grain quality and detect the grain humidity and the grain temperature, so that the grain outlet can be used as the operation speed of the grain discharging mechanism 15 to provide adjustment basis.

The working principle and the use flow of the utility model are as follows: a continuous circulation dual-purpose dryer is characterized in that the upper end of a lifting mechanism 2 is connected with the upper end of a drying tower 1, grains are filled into a hopper of a hopper 21 of the lifting mechanism 2, the grains are lifted to the top end of the drying tower 1 through the lifting mechanism 2, enter from a grain inlet 11, and a grain storage tower section 12 is used as a buffer section between the grain inlet 11 and a drying structure 13, so that the effect of temporarily storing the grains is achieved; in the drying tower section 131, the hot air blower 3a blows hot air provided by the heat source 4 into the drying tower section 131 to promote grain drying, particularly grain surface drying, in the buffer Su Dajie 132, water in the grain permeates to the grain surface, and then in the next drying tower section 131, grain is continuously dried; in the cooling tower section 14, the cold and hot dual-purpose fan 3b is communicated with the cold source 5, cold air is blown into the cooling tower section 14 to cool grains, in the grain discharging mechanism 15, the grain discharging mechanism 15 operates to enable the grains to be discharged from the grain outlet 16, and the grain discharging mechanism 15 controls the overall operation speed of the grains; the hot air supply amount of the heat source 4 and the cold air supply amount of the cold source 5 can be adjusted; the grain outlet 16 can observe grain quality and detect grain humidity and temperature. The above is a continuous process of grain in the dryer. When one continuous process cannot meet the drying requirement of the grains, the continuous process needs to be repeated, thereby forming a circulation process. In the circulation process, only the cold source of the cold and hot dual-purpose fan 3b is communicated at the end section of the circulation process, grains are cooled, and in other periods, the cold and hot dual-purpose fan 3b is communicated with the heat source, so that the grains are dried in a sustainable manner, and the drying efficiency is improved.
