Description

Technical Field

[0001] This utility model relates to the field of heating chamber technology, specifically a heating chamber for producing refractory materials. Background Technology

[0002] In the production process of refractory materials, a heating chamber is needed to heat and dry the semi-finished products. During the heating and drying process, the heat generated by the electric heating tubes generates hot air in the heating chamber to dry the semi-dried refractory materials. The high-temperature steam and flue gas generated during the heating process are discharged through the exhaust channel.

[0003] In traditional heating chambers, after heating and drying the air inside, some high-temperature air is generated. This air, which contains a lot of heat, is often directly discharged, resulting in a large loss of heat. Consequently, the drying efficiency of the refractory material inside the heating chamber is low, and the heat in the hot air cannot be utilized, resulting in energy loss. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a heating chamber for producing refractory materials, which has the advantages of reusing heat from hot air and keeping the heating chamber warm, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a heating chamber for producing refractory materials, comprising a chamber body, a chamber door rotatably connected to the outer wall of the chamber body, an insulation box fixedly mounted on the outer wall of the chamber body, a heating plate fixedly mounted on the inner wall of the chamber body, a placement rack installed in the inner cavity of the chamber body, a gas guide pipe fixedly mounted on the top of the chamber body, a recovery chamber fixedly mounted on the top of the chamber body, a heat-conducting pipe installed in the inner cavity of the recovery chamber, an insulation pipe installed in the inner cavity of the insulation box, a water pump fixedly mounted on the outer wall of the insulation pipe, a fixing rod fixedly mounted on the top of the recovery chamber, a top plate fixedly mounted on the top of the fixing rod, a sealing plug movably sleeved on the outer wall of the fixing rod, a return spring movably sleeved on the outer wall of the fixing rod, and a connecting pipe fixedly mounted on the outer wall of the heat-conducting pipe.

[0006] As a preferred technical solution of this utility model: the inner cavity of the air guide tube is connected to the inner cavity of the chamber, and the outer wall of the end of the air guide tube away from the chamber is connected to the inner cavity of the recovery chamber.

[0007] As a preferred technical solution of this utility model: the outer wall of the heat insulation pipe is in close contact with the outer wall of the chamber, and the outer wall of the end of the connecting pipe away from the heat conduction pipe is connected to the inner cavity of the heat insulation pipe.

[0008] As a preferred technical solution of this utility model: the top and bottom of the reset spring are in contact with the bottom of the sealing plug and the top of the recovery chamber, respectively, and the reset spring is made of high carbon steel.

[0009] As a preferred technical solution of this utility model: there are two insulated boxes, and the two insulated boxes are respectively installed on both sides of the outer wall of the chamber.

[0010] As a preferred technical solution of this utility model: the heat-conducting pipe is made of metallic copper, and the outer walls of the water pump are connected to the outer walls of the two insulation pipes on both sides respectively. The inner cavities of the heat-conducting pipe and the insulation pipe are filled with pure water.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This heating chamber for producing refractory materials uses a recovery chamber set on the top of the chamber body and a heat-conducting pipe installed in the inner cavity of the recovery chamber. By introducing the hot air generated by heating into the recovery chamber, the hot air can fully contact the outer wall of the heat-conducting pipe, thereby playing a role in temperature transfer. This allows the heat in the heated air to be transferred to the water, avoiding the direct discharge of hot air to the outside, which would result in a large amount of heat loss, thus achieving better drying of the refractory materials.

[0012] 2. This heating chamber for producing refractory materials uses a fixed rod on the top of the recovery chamber and a sealing plug on the outer wall of the fixed rod. The sealing plug can initially seal the inner cavity of the recovery chamber, allowing hot air to have more time to contact the heat-conducting pipe, thus better transferring heat. When a lot of air accumulates in the recovery chamber, the gas in the inner cavity of the recovery chamber can also be discharged to the outside, which can better keep the chamber warm and facilitate the drying of refractory materials.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 - Figure 5 A heating chamber for producing refractory materials includes a chamber body 1, a chamber door 2 rotatably connected to the outer wall of the chamber body 1, an insulation box 3 fixedly mounted on the outer wall of the chamber body 1, a heating plate 4 fixedly mounted on the inner wall of the chamber body 1, a placement rack 5 installed in the inner cavity of the chamber body 1, a gas guide pipe 6 fixedly mounted on the top of the chamber body 1, a recovery chamber 7 fixedly mounted on the top of the chamber body 1, a heat conduction pipe 8 installed in the inner cavity of the recovery chamber 7, an insulation pipe 9 installed in the inner cavity of the insulation box 3, a water pump 10 fixedly mounted on the outer wall of the insulation pipe 9, a fixing rod 11 fixedly mounted on the top of the recovery chamber 7, a top plate 12 fixedly mounted on the top of the fixing rod 11, a sealing plug 13 movably sleeved on the outer wall of the fixing rod 11, a return spring 14 movably sleeved on the outer wall of the fixing rod 11, and a connecting pipe 15 fixedly mounted on the outer wall of the heat conduction pipe 8.

[0017] In the above structure, the refractory materials that need to be dried can be placed on the top of the placement rack 5 on the inner wall of the silo 1, so that the refractory materials can be dried during the production process. The heating plates 4 on both sides of the inner wall of the silo 1 can increase the temperature in the inner cavity of the silo 1, thereby achieving the drying effect under high temperature.

[0018] In a preferred embodiment: the inner cavity of the air guide pipe 6 is connected to the inner cavity of the chamber 1, and the outer wall of the end of the air guide pipe 6 away from the chamber 1 is connected to the inner cavity of the recovery chamber 7.

[0019] In the above structure, the high-temperature gas generated in the inner cavity of the chamber 1 can be introduced into the inner cavity of the recovery chamber 7 by the air guide pipe 6 set on the top of the chamber 1. This allows the gas to come into contact with the outer wall of the heat pipe 8 in the inner cavity of the recovery chamber 7, thereby allowing the heat of the hot air to be transferred to the water in the inner cavity of the heat pipe 8, thus heating the water.

[0020] In a preferred embodiment: the outer wall of the insulation pipe 9 is in contact with the outer wall of the chamber 1, and the outer wall of the end of the connecting pipe 15 away from the heat conduction pipe 8 is connected to the inner cavity of the insulation pipe 9.

[0021] In the above structure, the insulation pipe 9 is installed on the outer wall of the chamber 1, and the connecting pipe 15 is installed on the outer wall of the heat conduction pipe 8. The insulation pipe 9 and the heat conduction pipe 8 are connected by the connecting pipe 15, so that the insulation pipe 9 and the heat conduction pipe 8 can be connected, and the water in the inner cavity of the heat conduction pipe 8 and the insulation pipe 9 can be interconnected.

[0022] In a preferred embodiment, the top and bottom of the return spring 14 contact the bottom of the sealing plug 13 and the top of the recovery chamber 7, respectively, and the return spring 14 is made of high carbon steel.

[0023] In the above structure, by setting a return spring 14 on the outer wall of the fixed rod 11, when the return spring 14 is installed on the outer wall of the fixed rod 11, the outer wall of the sealing plug 13 enters the inner cavity of the recycling chamber 7. At this time, the return spring 14 is in a stationary state, while the sealing plug 13 will enter the inner cavity of the recycling chamber 7 under the action of gravity, sealing the top of the recycling chamber 7.

[0024] In a preferred embodiment, there are two insulated boxes 3, and the two insulated boxes 3 are respectively installed on both sides of the outer wall of the compartment 1.

[0025] In the above structure, the insulation box 3 installed on the outer wall of the chamber 1 can completely wrap the insulation pipe 9 on the outer wall of the chamber 1, so that the temperature of the water in the inner cavity of the insulation pipe 9 will not be lost so quickly, thus better achieving the function of insulation of the inner cavity of the chamber 1 under the action of the insulation pipe 9.

[0026] In a preferred embodiment: the heat pipe 8 is made of metallic copper, and the outer ends of the water pump 10 are connected to the outer walls of the two heat insulation pipes 9 respectively. The inner cavities of the heat pipe 8 and the heat insulation pipes 9 are filled with pure water.

[0027] In the above structure, the heat-conducting pipe 8 installed in the inner cavity of the recovery chamber 7 causes the hot air in the inner cavity of the chamber 1 and the moisture contained in the material to evaporate, causing the gas in the inner cavity of the chamber 1 to expand outward and enter the inner cavity of the recovery chamber 7. This allows the hot air to come into contact with the outer wall of the heat-conducting pipe 8, thereby transferring the heat in the hot air to the water in the inner cavity of the heat-conducting pipe 8.

[0028] Working Principle: During the operation of the above equipment, when drying refractory materials, the refractory materials themselves contain a certain amount of moisture. The refractory materials are placed on top of the rack 5, and then heated by the heating plate 4 to dry the refractory materials inside the chamber 1. This raises the air temperature inside the chamber 1, causing the moisture in the refractory materials to evaporate and generate a large amount of water vapor. The hot air and water vapor then enter the inner cavity of the recovery chamber 7 through the air guide pipe 6, contacting the outer wall of the heat-conducting pipe 8. This transfers heat from the hot air to the water inside the heat-conducting pipe 8, raising the water temperature. The water pump 10 then pumps the heated water from the heat-conducting pipe 8 into the inner cavity of the insulation pipe 9, allowing the hot water to be heated further. The heat pipe 8 and the insulation pipe 9 circulate within their inner cavities. Since the outer wall of the insulation pipe 9 is in contact with the outer wall of the chamber 1, the insulation pipe 9 provides insulation for the outer wall of the chamber 1. When hot air enters the inner cavity of the recovery chamber 7, it gradually accumulates, increasing the pressure within the chamber. The gas remains in the chamber for a period of time, allowing sufficient time for the heat in the hot air to be transferred to the water in the inner cavity of the heat pipe 8. As the pressure in the inner cavity of the recovery chamber 7 increases, the sealing plug 13 is pushed upwards, causing it to detach from the inner cavity of the recovery chamber 7. This allows the air in the inner cavity of the recovery chamber 7 to be released outwards, effectively venting the gas and making better use of the heat in the exhaust gas.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
