Description

Technical Field

[0001] The utility model relates to the technical field of glass bottle production and processing, in particular to a simple heat preservation box. Background Art

[0002] Glass bottles are a common glass product, mainly used to hold various liquids or solid objects. They are made of high-temperature molten glass through blowing or pressing, and are transparent or translucent.

[0003] The raw materials for glass bottles mainly include quartz sand, soda ash, limestone, etc. These raw materials are crushed, mixed, melted and other processes to form liquid glass. The liquid glass then enters the mold, is blown or pressed into shape, and then annealed, cooled and other subsequent treatments to finally obtain the finished glass bottle.

[0004] Before the glass bottles are officially mass-produced, a small number of samples need to be made first, that is, "proofing", so that customers can confirm whether the design, quality, etc. meet their needs. After the samples are made, they need to be kept warm. Usually in mass production, due to the large number of products, an annealing furnace is usually used to anneal the products and then keep them warm. The annealing and insulation time takes two hours overall. When proofing, the number of products is small, and the samples only need to be kept warm for twenty minutes to produce results. If the sample glass bottles are placed in the annealing furnace for insulation, it will take a long time to wait, extending the sample production cycle. Therefore, the market needs a device that can anneal and keep warm the sample glass bottles separately to save insulation time and shorten the sample production cycle.

[0005] The prior art "An annealing and cooling device for glass bottle production and processing" (publication number: CN112250291A) discloses an annealing furnace that can anneal and keep glass products warm. However, the prior art still has the following technical problems:

[0006] The device of the prior art is suitable for annealing, heat preservation and cooling large quantities of glass bottles, but the number of sample glass bottles themselves is relatively small. If an annealing furnace is used to keep the samples warm during production, not only will the sample production cycle be extended due to the large number of feeding operation steps of the annealing furnace, but the production process of large quantities of products will be delayed due to the occupation of the annealing furnace, thereby reducing production efficiency. Utility Model Content

[0007] The utility model provides a simple heat preservation box, which can solve the problem in the prior art that when an annealing furnace is used to anneal and keep a sample glass bottle warm, the production efficiency of the mass product is easily reduced and the sample production cycle is prolonged.

[0008] The present application provides the following technical solutions: a simple thermal insulation box, comprising a support frame, a box body fixed on the support frame, and a box door hinged on the box body;

[0009] A heating device is fixedly connected to the box body, and the heating device includes a concave buckle fixed on the bottom surface of the box body and a U-shaped tube detachably connected to the concave buckle, a plurality of air holes are opened on the U-shaped tube, and a trumpet nozzle is threadedly connected to the air hole, and the trumpet nozzle includes a threaded round tube and a trumpet mouth fixed to the end of the threaded round tube, one end of the U-shaped tube is sealed with a plug, and the other end of the U-shaped tube is connected to a right-angle elbow, and the other end of the right-angle elbow extends below the bottom plate of the box body, and the end of the right-angle elbow extending below the bottom plate of the box body is connected to a threaded pipe, and a manual butterfly valve is connected below the threaded pipe, and the lower end of the manual butterfly valve is connected to an air pipe.

[0010] Beneficial effects:

[0011] The gas pipe can be connected to a gas cylinder to transport combustible gas into the gas pipe. The combustible gas is ejected from the air holes on the U-tube and ignited by an ignition needle. Similar to a gas stove, the combustible gas ejected from the air holes is burned. The trumpet nozzle is convenient for gathering the flame to the center of the box to make the temperature more concentrated, thereby improving the insulation effect of the glass bottle. The sample glass bottle is placed on the box bottom plate in the middle of the U-tube. The sample glass bottle can be heated and insulated by closing the box door, avoiding occupying the annealing furnace and eliminating the need for cumbersome loading and unloading operations when using the annealing furnace, thereby shortening the sample production cycle and improving production efficiency.

[0012] Furthermore, a threaded hole is provided on the concave buckle, a screw is connected in the threaded hole, and the threaded head of the screw presses the U-shaped tube tightly.

[0013] Beneficial effect: The U-shaped tube is conveniently fixed by using the concave buckle and the screw, thereby improving the stability of the U-shaped tube in the box.

[0014] Furthermore, the box body is also connected to a smoke exhaust pipe.

[0015] Beneficial effect: Since smoke is generated when the flame burns in the box, the smoke exhaust pipe can easily discharge the smoke out of the box.

[0016] Furthermore, a block is fixed on the side wall of the box door, and a U-shaped notch is provided on the block. A locking mechanism is fixed on the side of the box body away from the box door, and the locking mechanism includes a sleeve fixed on the side of the box body. Two sleeves are provided, and a rotating shaft is rotatably connected between the two sleeves. A threaded column is fixedly connected in the middle of the rotating shaft, and a handwheel is threadedly connected to the threaded column, and the diameter of the threaded column is smaller than the opening diameter of the U-shaped notch on the block.

[0017] Beneficial effect: After closing the door, swing the hand wheel to make the threaded column fit into the U-shaped notch on the block, and then tighten the hand wheel to tighten the door, ensuring that the hot air in the box will not be lost quickly, thereby enhancing the thermal insulation effect.

[0018] Furthermore, the handwheel comprises a threaded sleeve threadedly connected to a threaded column, three inclined rods are evenly fixed on the threaded sleeve, and a circular ring is fixed on one end of the inclined rod away from the threaded sleeve.

[0019] Beneficial effect: By rotating the ring, the entire hand wheel can be tightened, and the threaded sleeve can be moved close to the box body, thereby pressing the stopper, locking the box door, and improving the tightness of the box door after closing. BRIEF DESCRIPTION OF THE DRAWINGS
