Description

Technical Field

[0001] The utility model relates to the field of heat treatment, in particular to a trolley movable charcoal baking furnace. Background Art

[0002] During the melting and casting process of copper and copper alloys, charcoal needs to be covered on the surface of the molten metal. Charcoal has three main functions: 1. It prevents the surface of the copper liquid from contacting with the air and oxidizing; 2. It keeps the heat insulated to prevent excessive heat dissipation; 3. It reduces metal oxides. However, charcoal is easy to absorb moisture during production, transportation, and storage, especially in the rainy season and when the indoor humidity is high. When wet charcoal is covered on the surface of the molten metal, it will cause defects such as pores and looseness in the copper and copper alloy ingots, eventually resulting in product scrapping. The contact between water vapor and high-temperature copper liquid will also cause explosions and accidents. The calcined charcoal is required to have extremely low moisture content and good water absorption. Therefore, a proprietary equipment is needed to bake and dehumidify the charcoal.

[0023] The present invention is further described in detail below in conjunction with the accompanying drawings, wherein the same components are represented by the same figure numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower", "bottom surface" and "top surface" used in the following description refer to directions in the drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Design concept: Design a product by adding a set of bidirectional lifting rollers to the original equipment to meet the needs of bidirectional and double-layer specific heavy-duty heat treatment equipment.

[0026] Example:

[0027] like Figure 1-Figure 4 As shown, the technical solution provided by the utility model is a trolley-mobile charcoal baking furnace, comprising a furnace body 1 and a furnace lining 2, four heating chambers 3 are arranged in the furnace body 1, an inner lining plate 4 is arranged in the heating chamber 3, each heating chamber 3 is provided with a furnace door 5, and further comprises a material frame 6, a material trolley 7, a heating pipe 8 and a dehumidification pipe 9, heating pipes 8 are arranged on both sides of the heating chamber 3, fins 14 are arranged on the heating pipe 8, there are twelve heating pipes 8, which are symmetrically arranged on both sides of the heating chamber 3; the material trolley 7 carries a material frame 6, a heat-resistant universal caster 16 is arranged at the bottom of the material frame 6, the material trolley 7 is also provided with a handle 17, the material trolley 7 moves horizontally from the heating chamber 3, and an upper cover plate 12 is provided on the material frame 6, and a lifting ring 13 is fixed on the upper cover plate 12 for easy lifting.

[0028] This embodiment further includes a guide rail 10 . The guide rail 10 is disposed in the heating chamber 3 . The trolley 7 translates along the guide rail 10 . A guide rail 11 is disposed at the front section of the guide rail 10 outside the furnace door 5 .

[0029] This embodiment further includes a main pipeline 15 , and a dehumidification pipeline 9 is provided on the top of the heating chamber 3 , and each dehumidification pipeline 9 is connected to the main pipeline 15 .

[0030] Working principle:

[0031] This product is different from the traditional baking furnace in that the loading form adopts a trolley mobile structure, and a relatively sealed material frame 6 for charcoal is placed on the trolley (not completely sealed, after the material frame 6 is covered with the upper cover plate 12, there is still a small gap to allow moisture to be discharged; but it cannot be completely open to avoid ignition of charcoal during high-temperature baking and causing charcoal burning). A baking furnace is equipped with four relatively independent heating chambers 3. Heating tubes 8 with stainless steel fins 14 are arranged on both sides of each heating chamber 3 for radiation heating. The fins 14 on the surface improve the heat dissipation efficiency of the heating tube 8, thereby accelerating the heating speed of the charcoal and shortening the baking time. In addition, a dehumidification pipe 9 is provided on the top of each heating chamber 3, which is collected through the main pipe 15 and discharged outside the workshop; each heating chamber 3 is provided with a left and right opening and closing furnace door 5, which is tightened by a hand wheel to reduce heat loss.

[0032] This product can be equipped with four trolleys 7 at the same time. Each trolley 7 is equipped with four heat-resistant universal casters 16 at the bottom, two of which are equipped with brakes, which are convenient for dragging and stopping the trolley 7. The trolley 7 is also equipped with a special handle 17 for dragging the trolley in and out of the furnace. The trolley 7 guide rails 10 and guide rails 11 are installed at the bottom of each heating chamber 3, which is convenient for the trolley to enter the baking furnace more smoothly. The four-chamber baking furnace can handle the baking work of four frames of charcoal at the same time, and the baked charcoal can be used in small quantities in multiple frames. After a basket is used, it can be immediately supplemented with a spare frame 6 for baking, so as to avoid moisture failure caused by staying too long before use. It is convenient, flexible and efficient to use.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
