Technical Field
[0001] The utility model relates to the field of grain storage, in particular to a ventilation and heat preservation device for a grain depot. Background Art
[0002] A grain depot is an important place for unified storage and management of grain. In order to ensure the quality of grain size, it is necessary to control the temperature and humidity in the grain depot. However, due to climate change in the area where the grain depot is located, the temperature and humidity in the grain depot will be further affected. Therefore, a ventilation and heat preservation device is needed in the grain depot to ensure that the grain can be stored for a longer time and is not rotten due to moisture or high temperature, thereby causing economic losses. However, the existing ventilation and heat preservation devices for grain depots are not convenient for adjusting the temperature and humidity inside the grain, and when the temperature is low, there is a lack of necessary heat preservation devices to increase the storage temperature of the grain. Therefore, a ventilation and heat preservation device for grain depots is needed to solve the problems of adjusting the temperature and humidity inside the grain and the poor heat preservation effect in the grain depot.
[0003] A Chinese patent with publication number CN208480319U discloses an intelligent ventilation control system for a grain depot, comprising a shell, a partition is fixed between the inner walls on both sides of the shell, a bidirectional motor is installed in the middle of the top inner wall of the shell, a driving pulley is fixed to the output shaft of the bidirectional motor, a driven pulley is arranged on both sides of the driving pulley, a belt is sleeved between the driving pulley and the driven pulley, a threaded rod is fixed to the middle of the bottom end of the driven pulley, a moving block is threadedly connected to the threaded rod, openings are provided on both sides of the shell, card slots are provided at both ends of the opening, filter plates are provided inside the two groups of openings, and two groups of fixed slots are provided on the side away from the two groups of filter plates. The device is novel in design, reasonable in structure, simple in operation, highly intelligent, labor-saving, convenient for ventilation of the grain depot, and convenient for adjusting the temperature and humidity in the grain depot, and can effectively prevent the influence of the external environment on the grain depot environment. It is highly practical and suitable for promotion.
[0004] In the above patent, the ventilation and heat preservation device is arranged on both sides of the shell. In actual use, it can only adjust the temperature of the surface of the grain in the shell, and cannot detect the actual temperature inside the grain. In addition, the temperature sensor of the device is arranged on the inside of the shell, and also cannot deeply detect the actual temperature environment inside the grain. Utility Model Content
[0005] The utility model aims to provide a ventilation and heat-insulating device for a grain warehouse, which can flexibly adjust the dust suppression area according to the floating degree of flour in the workshop, and can recycle the flour collected by the dust suppression, and has the advantages of good dust suppression effect and not easy to waste flour.
[0006] The utility model aims to provide a ventilation and heat-insulating device for a grain depot, comprising a grain depot body, a ventilation duct fixedly arranged on one side of the grain depot body, a ventilation component arranged in the ventilation duct, a heat exchanger fixedly arranged on one side of the bottom of the grain depot body, a plurality of main ventilation ducts arranged at the bottom of the grain depot body, more than one auxiliary ventilation duct one is vertically fixedly arranged on the main ventilation duct, more than one ventilation opening is evenly distributed on the auxiliary ventilation duct one, a temperature and humidity sensor is fixedly installed on the top of the auxiliary ventilation duct one, and two adjacent main ventilation ducts are connected by an auxiliary ventilation duct two.
[0007] Furthermore, the ventilation component includes a fan and a drive motor, a bevel gear 1 is fixedly connected to one side of the fan, the drive motor is fixedly arranged at the bottom of the ventilation duct, a bevel gear 2 is fixedly arranged on the output end of the drive motor, and the bevel gear 1 and the bevel gear 2 are meshed.
[0008] Furthermore, an air collecting pipe is fixedly arranged on one side of the ventilation duct, and the air collecting pipe is connected with the main ventilation pipe.
[0009] Furthermore, one end of the heat exchanger is fixedly connected to the air collecting pipe, and the other end is fixedly connected to the main ventilation pipe.
[0010] Furthermore, both ends of the main ventilation pipe are fixed to the bottom of the grain storage body through fixed brackets.
[0011] Furthermore, a heat-insulating plate is embedded in the shell of the grain storage body.
[0012] The working principle and use principle of the utility model are as follows: the device drives the bevel gear 1 to rotate through the driving motor, thereby driving the bevel gear 2 and the fan to rotate, and the rotating fan draws external wind into the air collecting duct. When it is necessary to improve the ventilation effect, the wind is transported to each main ventilation duct in turn through the air collecting duct, and the wind is transported to the auxiliary ventilation duct 1 through the main ventilation duct. The auxiliary ventilation duct is vertically arranged on the main ventilation duct, and the wind is evenly transported to the inside of the grain through the auxiliary ventilation duct 1. When the temperature inside the grain depot is greatly different from the external temperature, the wind sucked by the fan is heated by the heat exchanger and transported to the inside of the grain, thereby increasing the temperature inside the grain. An insulation board is embedded in the shell of the grain depot body, and the insulation board is used to effectively isolate the external air or hot air. The temperature and humidity sensor can monitor the temperature inside the grain in real time, which is convenient for operating the driving motor and the heat exchanger separately, so that the air and temperature inside the grain depot body are in a balanced stage as much as possible.
[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: the device inhales external air through the ventilation device and ventilates and insulates the air inside the grain through the auxiliary ventilation pipe on the main ventilation pipe, thereby improving the ventilation effect of the grain depot and achieving comprehensive ventilation and insulation of the grain. The temperature of the grain in the depot is monitored in real time by a temperature and humidity sensor, which facilitates the adjustment of the temperature of the conveying air at any time. The heat exchanger is convenient for heating the grain depot in cold weather to avoid frostbite and damage to the grain. The insulation board effectively isolates the temperature outside the grain depot, further improving the insulation effect of the grain depot. BRIEF DESCRIPTION OF THE DRAWINGS
