Description

Technical Field

[0001] The utility model belongs to thermal equipment attached to a shuttle kiln body, in particular to a shuttle kiln top pressure equalizing device. Background Art

[0002] Shuttle kiln is an intermittent kiln, and its sealing is extremely important, which is related to important indicators such as firing temperature, heating speed, and energy consumption of shuttle kiln. The kiln roof of shuttle kiln is built with refractory bricks. Some products often produce a large amount of volatile gas when heated in the kiln. Due to the long-term operation of the kiln, gaps will appear at the bonding points of bricks, which will not only cause a large amount of heat loss in the furnace, but also affect the workshop production environment due to the escape of harmful volatile gases (such as white smoke and glue gas). Utility Model Content

[0003] The utility model aims to provide a shuttle kiln top pressure equalizing device which has reasonable structure, stable operation, environmental protection, energy saving and durability for the shuttle kiln.

[0004] The technical solution of the utility model is: it includes a kiln body steel structure, a kiln roof, a kiln wall, a furnace and an electrical automatic control device, etc., a sealing plate is arranged above the kiln roof, the sealing plate is connected to the top of the kiln body steel structure through a bolt assembly, so that a closed space is formed between the kiln roof and the sealing plate, and an air supply pipeline with a regulating valve is arranged at the center of the sealing plate, and the air supply pipeline is connected to a branch pipeline arranged on the burner combustion-supporting air pipeline.

[0005] Furthermore, a heat preservation ring made of heat preservation material is arranged inside the steel structure of the kiln body between the kiln roof and the sealing plate, and the top surface of the heat preservation ring is in close contact with the bottom surface of the sealing plate.

[0006] The sealing plate is connected to the steel structure of the kiln roof by bolts. The bolt connection is made for easy disassembly and convenient maintenance of the kiln body. The inner side of the steel structure of the kiln roof is surrounded by a circle of insulation materials, which is more conducive to the insulation and sealing of the gas. The preheated hot air fills the pressure equalizing device through the pipeline. The air pressure in the pressure equalizing device is balanced with the air pressure in the kiln. The gas in the kiln no longer leaks out, reducing heat loss.

[0007] The utility model has the beneficial effects that the air pressure of the pressure equalizing device is balanced with the air pressure in the kiln, the gas in the kiln no longer leaks out, and the heat loss is reduced. The pressure equalizing device makes full use of the waste heat of the kiln exhaust smoke, and plays a role in heat preservation while sealing the gas in the kiln. It has the advantages of reasonable structure, stable operation, environmental protection and energy saving, and durability, and can be widely used in shuttle kilns for producing various products.

[0008] The utility model will be further described below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1This is a schematic diagram of the main structure of the utility model.

[0010] In the figure: 1 is a sealing plate, 2 is a bolt assembly, 3 is a heat preservation ring, 4 is an air supply pipeline, 5 is a regulating valve, 6 is a kiln body steel structure, and 7 is a furnace.

[0011] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings and by listing the preferred embodiments of the present invention. Implementation

[0012] like Figure 1 As shown, the shuttle kiln top pressure equalizing device is composed of a kiln steel structure 6, a kiln top, a kiln wall, a furnace 7 and an electrical automatic control device. A sealing plate 1 is arranged above the kiln top, and the sealing plate 1 is connected to the top of the kiln steel structure 6 through a bolt assembly 2, and an air supply pipe 4 with a regulating valve 5 is arranged in the center of the sealing plate. At the same time, an insulation ring 3 made of insulation material is arranged on the inner side of the kiln steel structure 6 between the kiln top and the sealing plate 1. The top surface of the insulation ring 3 is in close contact with the bottom surface of the sealing plate 1, which can play a role of insulation and sealing. The air supply pipe 4 welded on the sealing plate 1 can directly input hot air. When implementing the utility model, the operator only needs to open the regulating valve 5, and the hot air fills the kiln top through the air supply pipe 4. Under the control of the electrical automation device, the gas in the space between the kiln top and the sealing plate 1 is kept balanced with the gas in the kiln furnace 7, thereby reducing the loss of gas in the kiln through the brick joints and extending the service life of the kiln top. It has the advantages of reasonable structure, stable operation, environmental protection, energy saving, durability, etc. It can be widely used in shuttle kilns for producing various products.

[0013] The above description is only a detailed description of a specific embodiment of the utility model, but the structural features of the utility model are not limited thereto. Any changes or modifications made by any technician in the field of the utility model are covered by the scope of the utility model patent.
