Description

Technical Field

[0001] This utility model relates to the field of grain storage equipment technology, specifically a grain storage temperature and humidity control device. Background Technology

[0002] Grain silos are specialized facilities for storing grain. Before storage, grain requires pre-treatment, starting with drying to reduce its moisture content to 12.5%-13.5%. Next, impurities are removed, eliminating any impurities introduced during harvesting, threshing, and drying. Finally, new and old grains are separated and stored in the silos. Grain storage requires low-temperature ventilation. Existing small grain silos use axial flow fans installed through openings in the side walls for exhaust ventilation. While these fans are effective for ventilating grain piled near the side walls, they are less effective for grain piled in the center due to the greater distance and excessive grain obstruction. Therefore, ventilation through the side wall fans is inefficient and ineffective for grain in the center of the silo.

[0003] To address the aforementioned issues, the utility model patent with authorization announcement number CN217523284U discloses a ventilated grain silo structure. This device incorporates multiple ventilation pipes within the grain silo body, each with multiple air inlets. Both the ventilation pipes and air inlets extend close to the center of the grain silo body. Some of the ventilation pipes are used to exhaust air from the center of the grain silo body, while others allow external gas to enter the grain silo body, thereby effectively improving the ventilation efficiency at the center of the grain silo body.

[0004] However, in actual use, the grain silo cannot keep the grain moist. In an overly dry environment, the grain is prone to excessive water loss, which reduces the quality of the grain and fails to meet the usage requirements. Utility Model Content

[0005] The purpose of this invention is to provide a grain storage temperature and humidity control device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A grain storage temperature and humidity control device includes: a storage body with a storage roof installed at its upper end; a humidification mechanism installed on the right outer wall of the storage body for delivering humid and cool air into the storage body; the humidification mechanism includes a humidification rack installed on the right outer wall of the storage body, a humidification box installed on the humidification rack, a humidification pipe installed on the humidification box, the humidification pipe extending into the storage body, a humidification pump installed on the humidification pipe, and an air inlet pipe installed on the humidification box; and an internal circulation mechanism installed on the left outer wall of the storage body for realizing air circulation within the storage body.

[0008] As a preferred embodiment, the humidification rack is also equipped with a liquid storage tank, the liquid storage tank is equipped with an infusion pipe, the end of the infusion pipe extends into the humidification box and is equipped with an atomizing nozzle, and the infusion pipe is also equipped with an infusion pump.

[0009] As a preferred embodiment, the internal circulation mechanism includes a ground cage assembly installed at the bottom of the silo body and a circulation assembly installed in the upper part of the silo body.

[0010] As a preferred embodiment, the ground cage assembly includes an exhaust pipe installed at the bottom of the chamber, a plurality of exhaust columns are distributed on the exhaust pipe, a cover plate is installed on the exhaust pipe, and a through hole is opened on the cover plate corresponding to the position of each exhaust column. The exhaust column is inserted into the corresponding through hole. An exhaust pipe is also installed at the end of the exhaust pipe. The exhaust pipe passes through the chamber and is equipped with an exhaust valve. An exhaust pump is also installed on the exhaust pipe.

[0011] As a preferred embodiment, the circulation assembly includes an air outlet pipe installed inside the chamber, a circulation pipe installed on the air outlet pipe, a negative pressure pipe installed on the exhaust pipe, an end of the negative pressure pipe connected to the suction end of a negative pressure pump, an exhaust end of the negative pressure pump connected to the circulation pipe, and a negative pressure valve installed on the negative pressure pipe.

[0012] As a preferred embodiment, a temperature sensor and a humidity sensor are also installed inside the chamber, and a controller is also installed on the outer wall of the chamber. The temperature sensor, humidity sensor, negative pressure valve, negative pressure pump, exhaust valve, exhaust pump, humidification pump, and infusion pump are all electrically connected to the controller.

[0013] As a preferred embodiment, a door is also hinged to the front side of the compartment.

[0014] Compared with existing technologies, the beneficial effects of this invention are as follows: When humidification is required inside the storage chamber, the humidification pump is turned on, drawing in cool, humid air from outside through the air inlet pipe. This air is then introduced into the storage chamber through the humidification pipe, increasing the humidity inside and effectively preventing excessive moisture loss in the grain, which could lead to a decrease in grain quality. When the external air humidity is insufficient to meet the humidification requirements, the infusion pump is activated to deliver the humidifying liquid (clean water) from the storage tank to the infusion pipe, which is then sprayed out through the atomizing nozzle to increase the humidity of the air inside the humidification chamber. This invention has a reasonable structure, effectively moisturizes grain, prevents excessive moisture loss and reduces grain quality, and better meets usage needs. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Please refer to Figures 1-5 A grain storage temperature and humidity control device includes: a storage body 1, with a storage door 11 hinged to the front side of the storage body 1, and a storage roof installed at the upper end of the storage body 1; a humidification mechanism 3, installed on the right outer wall of the storage body 1, for delivering humid and cool air into the storage body 1; the humidification mechanism 3 includes a humidification rack 31 installed on the right outer wall of the storage body 1, a humidification box 33 installed on the humidification rack 31, and a humidification pipe 34 installed on the humidification box 33, the humidification pipe 34 extending into the storage body 1. The humidification pipe 34 is also equipped with a humidification pump 35, and the humidification box 33 is equipped with an air inlet pipe 32. The internal circulation mechanism 2 is installed on the outer left side of the chamber 1 to realize the air circulation within the chamber 1. In this embodiment, the humidification rack 31 is also equipped with a liquid storage tank 36, and the liquid storage tank 36 is equipped with an infusion pipe 37. The end of the infusion pipe 37 extends into the humidification box 33 and is equipped with an atomizing nozzle. The infusion pipe 37 is also equipped with an infusion pump 38.

[0023] The working principle of this utility model is as follows: When it is necessary to humidify the inside of the storage chamber 1, the humidification pump 35 is turned on, and the cold and humid air outside is drawn into the humidification chamber 33 through the air inlet pipe 32. Then, the cold and humid air is input into the storage chamber 1 through the humidification pipe 34, which can increase the humidity inside the storage chamber 1 and effectively prevent the grain from losing too much water, thereby reducing the quality of the grain. When the humidity of the outside air is not enough to meet the humidification requirements, the liquid pump 38 is started to deliver the humidification liquid (clean water) in the storage tank 36 to the liquid delivery pipe 37, and then sprayed out by the atomizing nozzle to increase the humidity of the air inside the humidification chamber 33.

[0024] As a further embodiment, the internal circulation mechanism 2 includes a ground cage assembly installed at the bottom of the chamber 1 and a circulation assembly installed in the upper part of the chamber 1. The ground cage assembly includes an exhaust pipe 214 installed at the bottom of the chamber 1. A plurality of exhaust columns 213 are distributed and installed on the exhaust pipe 214. A cover plate 211 is installed on the exhaust pipe 214. The cover plate 211 has a through hole 212 corresponding to the position of each exhaust column 213. The exhaust column 213 is inserted into the corresponding through hole 212. An exhaust pipe 21 is also installed at the end of the exhaust pipe 214. The exhaust pipe 21 penetrates the chamber 1 and is equipped with an exhaust valve 23. An exhaust pump 22 is also installed on the exhaust pipe 21.

[0025] The circulation assembly includes an exhaust pipe 28 installed inside the chamber 1, a circulation pipe 27 installed on the exhaust pipe 28, a negative pressure pipe 24 installed on the exhaust pipe 21, the end of the negative pressure pipe 24 being connected to the suction end of the negative pressure pump 26, the exhaust end of the negative pressure pump 26 being connected to the circulation pipe 27, and a negative pressure valve 25 being installed on the negative pressure pipe 24.

[0026] The working principle of the internal circulation mechanism 2 is as follows: When the air inside the storage chamber 1 is dry and hot in summer, the humidification mechanism 3 humidifies the air inside the storage chamber 1. Then, the exhaust valve 23 is closed and the negative pressure valve 25 is opened. Then, the negative pressure pump 26 is started. The air inside the storage chamber 1 enters the exhaust pipe 214 through the exhaust column 213. Then, it is transferred to the circulation pipe 27 through the negative pressure pipe 24. The circulation pipe 27 then delivers the air to the exhaust pipe 28 and blows it out from the upper part of the storage chamber 1. This realizes the air flow inside the storage chamber 1, which makes it easier to control the humidity of the storage chamber 1 to maintain within a certain range and improve the preservation effect of grain.

[0027] When humidifying in winter, the humidifying mechanism 3 delivers humid and cold air into the chamber 1. Then, the negative pressure valve is closed, the exhaust valve 23 is opened, and the exhaust pump 22 is started. The air in the chamber 1 is transferred to the exhaust pipe 214 through the exhaust column 213 and then discharged through the exhaust pipe 21. This replaces the high temperature air in the chamber 1 with low temperature air, thereby achieving the purpose of reducing the internal temperature of the chamber 1 and controlling humidity and retaining water.

[0028] As a further embodiment, a temperature sensor 12 and a humidity sensor 13 are also installed inside the chamber 1, and a controller 14 is installed on the outer wall of the chamber 1. The temperature sensor 12, humidity sensor 13, negative pressure valve 25, negative pressure pump 26, exhaust valve 23, exhaust pump 22, humidification pump 35, and infusion pump 38 are all electrically connected to the controller 14. In this embodiment, the negative pressure valve 25 and the exhaust valve 23 are both solenoid valves.

[0029] By setting temperature sensor 12 and humidity sensor 13, it is convenient to monitor the temperature and humidity inside the chamber 1, thereby facilitating the control of humidification mechanism 3 to humidify the inside of chamber 1 and controlling internal circulation mechanism 2 to achieve air circulation inside chamber 1, so that the humidity inside the chamber can be controlled within a certain range, preventing excessive humidity differences at different locations inside chamber 1.
