Circulation fumigation system
Food security is a strategic matter related to the national economy and people's livelihood, and strengthening the supervision of grain stocks can enhance the government's macroeconomic regulation and control of grain and its ability to resist risks, and ensure that the government can mobilize and use it when needed. At present, the management of grain inventory storage quantity is usually based on the measurement accounting method or on-site manual measurement method when entering and exiting the warehouse to determine the quantity of grain in the warehouse and the vacant warehouse capacity. Therefore, if the inventory is abnormal or the reserve grain is used without permission, it cannot be warned in time, and the competent department cannot accurately grasp the storage quantity and warehouse capacity of the scattered grain depots in real time, and this information is of great significance to the allocation of grain in and out of the warehouse.
The system is composed of a network management platform and the measurement and control module of the granary scattered around the country, and the working principle is:
1. Firstly, the height of the grain surface is measured by ultrasonic, and then the actual volume of the grain pile is calculated according to the bottom area of the warehouse and the error correction module;
2. According to the "bulk density estimation" module coordinated by moisture, storage year, variety and impurities, the measured quantity of grain in the warehouse is calculated;
3. Compare the measured quantity with the book quantity, analyze whether it is abnormal, and report the alarm by email and SMS if the threshold is exceeded;
4. It can automatically generate the physical working paper of the warehouse inspection and the vacancy table of the warehouse capacity of the grain depots in various places, which greatly improves the efficiency of the warehouse inspection and the deployment of the warehouse.
The higher-level supervision departments and custodians log in to the system through the browser to realize the remote and real-time visual monitoring of the grain depots in various places to ensure that the number of grain storage is authentic and credible.
Close doors and windows
The LPM series grain silo sealing door and LPC series grain silo sealing window developed and produced by our company have the characteristics of good sealing and thermal insulation performance, high strength, exquisite design, excellent production, reliable performance, convenient operation, etc., the material is hot-rolled equilateral angle steel, and the skeleton is made of cold-formed rectangular hollow steel; The veneer is made of high-quality galvanized sheet, and different color plates can also be used according to user requirements, filled with thermal insulation and flame retardant materials; The sealing strip adopts a five-fold mouth sealing strip with corrosion resistance, aging resistance and long-lasting tensile strength. This series of products is an indispensable important infrastructure and an ideal replacement product for the construction of modern grain depots.
Ventilation ducts
The storage ventilation duct produced by our company is generally made and produced according to the user's own design and requirements, or designed and produced on behalf of the user according to the user's requirements.
There are two kinds of grain storage ventilation pipes: above-ground cage ventilation and underground trough ventilation. The material of grain storage ventilation mesh plate is generally 15mm or 2mm cold-rolled high-quality steel plate. There are four types of holes in the mesh plate: waist round hole, round hole, fish scale and bridge double-sided hole. The opening rate of the waist round hole is more than 30%, the opening rate of the hole is 30%, the opening rate of the fish scale hole is 28%, and the opening rate of the bridge double-sided hole is more than 35%. The surface plate of the ventilation plate is specially treated with color galvanized or white plating, which has the characteristics of oxidation resistance, corrosion resistance and beautiful appearance.
Centrifugal ventilators
The complete sets of mobile centrifugal ventilators produced by our company are mainly used for ventilation and cooling of national standard granaries and non-standard granaries for grain storage. The machine is compact in structure, easy to move, can meet different working occasions, and is a special fan designed with the national grain reserve.
