Detachable combined modular tobacco leaf natural gas curing barn

Abstract

The invention discloses a detachable combined modular tobacco leaf natural gas curing barn which comprises a tobacco containing chamber and a heating chamber, a heat insulation wall is arranged between the tobacco containing chamber and the heating chamber and provided with an air inlet and an air return opening, natural gas heating equipment is arranged in the heating chamber, the tobacco containing chamber is connected into a closed space through polyurethane composite plates, a tobacco blocking frame is arranged in the tobacco containing chamber, and a tobacco containing door is arranged on an end wall. The heating chamber and the heat insulation wall are formed by assembling rock wool composite boards, U-shaped covered edges are fixed to the end faces of the polyurethane and rock wool composite boards, lap joint boards are arranged between the adjacent polyurethane and / or rock wool composite boards, and the heat insulation wall is connected with the polyurethane and rock wool composite boards through screws penetrating through the lap joint boards and the U-shaped covered edges. The adjacent polyurethane and rock wool composite boards are connected through screws penetrating through the lap joint boards and the U-shaped covered edges. According to the different working temperatures of the tobacco containing chamber and the heating chamber, the curing barn is formed by detachably combining different plates, the construction is convenient and flexible, repeated utilization can be achieved, the heat preservation effect is good, the maintenance is convenient and fast, and safety and reliability are achieved.

Description

technical field [0001] The invention belongs to the field of tobacco preparation equipment, and in particular relates to a detachable and combined modular tobacco leaf natural gas curing barn, which is convenient and flexible in construction, can be reused many times, has good heat preservation effect, is convenient in maintenance, and is safe and reliable. Background technique [0002] Tobacco seedling raising, planting, picking and curing are the four key links that determine the quality and benefits of tobacco leaves, and tobacco leaf curing is also the most uncontrollable link in tobacco leaf production, with the highest risk, the greatest loss and high cost. Therefore, a barn with a reasonable structure, convenient use and easy control of the overall cost is the key issue to solve the stable tobacco production. [0003] At present, flue-cured tobacco is generally promoted to use dense curing rooms. Most of the walls are constructed of traditional building materials such...

Problems solved by technology

However, the dense barns built with traditional building materials are inconvenient to disassemble and transfer for reuse. As a result, the barns matching the tobacco fields after continuous crop rotation are vacant, and new barns need to be built in new areas. Not only the construction period is long, but also the construction is repeated. It causes a great waste of resources, increases the production cost of tobacco leaves, and reduces the production enthusiasm of farmers

For this reason, in the prior art, there are also some plate-type intensive barns and mobile intensive barns. For the convenience of construction and management, they are generally constructed with a single polyurethane board, polystyrene board and other necessary steel frames. Although they are easy to dismantle It can be installed and reused, but a single plate is difficult to adapt to the different operating temperatures of the heating chamber and the smoke chamber, and there are safety hazards or excess safety; and the investment and construction process requires a steel frame as a skeleton support, so it is necessary to build a foundation for fixing the skeleton in advance , resulting in a long construction period, high cost, complicated disassembly and assembly of the skeleton connection, and the plate is directly fixed on the skeleton by bolts, it is difficult to effectively seal the gap between the plates, and due to the thermal expansion and contraction of the material and the bolts, it will also cause It is difficult to guarantee the sealing of seams and bolted joints, and the thermal insulation performance is low
