Description

Technical Field

[0001] The utility model provides a kiln for ceramic production, belonging to the technical field of kilns. Background Art

[0002] When ceramics are produced, they are placed in a kiln for sintering. The powder particles in the ceramic raw materials will sinter at high temperatures, and the particles will combine with each other to form a dense structure. This can increase the density and hardness of the ceramics and give them better physical properties. When sintering ceramics, some harmful exhaust gases will be generated in the kiln, which often contain sulfur dioxide, nitrogen oxides, etc. Therefore, these exhaust gases need to be discharged when the kiln is working.

[0003] In the prior art, the waste gas discharged from the kiln often carries a large amount of heat. In order to save and utilize energy, before the waste gas is treated, it is often necessary to recover the waste heat and use the heat in the waste gas to heat a specific medium. However, the prior art is not convenient for adjusting the heat recovery process. When the temperature in the kiln is too high, it often leads to a large amount of heat recovery, which is not conducive to the precise control of the heat recovery process. Therefore, the existing kiln heat recovery structure needs to be improved. Utility Model Content

The heat insulation block is fixedly connected to the top of the heat recovery plate, and the heat insulation plate is fixedly connected to one side of the heat recovery plate.

DETAILED DESCRIPTION

[0018] The utility model is further described below in conjunction with the accompanying drawings.

[0019] according to Figure 1-4 As shown: The utility model provides a kiln for ceramic production: it includes a furnace body 1, a heating structure 2 is arranged in the furnace body 1, and an exhaust gas exhaust pipe 3 is connected to one side of the furnace body 1; a heat recovery box 4 connected to the exhaust gas exhaust pipe 3 is fixedly arranged on one side of the furnace body 1, and a processing pipe 8 is connected to the heat recovery box 4; a control cabinet 7 capable of controlling the heating structure 2 is arranged on one side of the furnace body 1; a heat recovery structure is arranged in the heat recovery box 4, a heat conduction box 6 is arranged on one side of the furnace body 1, a heat recovery medium is arranged in the heat conduction box 6, the heat recovery medium is water, and the heat recovery structure is connected to the heat conduction box 6; a fixed box 9 is fixedly arranged on one side of the furnace body 1, a lifting structure is arranged in the fixed box 9, and the lifting structure is fixedly connected to the heat recovery structure; a temperature sensor 18 is arranged in the heat conduction box 6, and the control cabinet 7 is circuit-connected with the temperature sensor 18.

[0020] The temperature sensor 18 can monitor the temperature of the heat recovery medium in the heat transfer box 6. By setting a lifting structure, the heat recovery structure can be pulled out of the heat recovery box 4, so that heat recovery can be stopped when the temperature of the heat recovery medium is high, thereby ensuring that the heat recovery medium is within an appropriate temperature range.

[0021] The heat recovery structure includes a heat recovery plate 5, a heat insulation block 11, and a heat insulation plate 10. The heat insulation block 11 is fixedly connected to the top of the heat recovery plate 5, and the heat insulation plate 10 is fixedly connected to one side of the heat recovery plate 5. The inner wall of the heat recovery box 4 is provided with a card slot 12 corresponding to the heat insulation block 11; the heat recovery plate 5 extends out from the heat recovery box 4.

[0022] The heat recovery plate 5 can exchange heat with the exhaust gas, thereby introducing heat into the heat conduction box 6; the setting of the heat insulation plate 10 can reduce the heat entering the other half of the heat recovery box 4 through the heat recovery plate 5, and the setting of the heat insulation plate 10 can prevent the heat of the heat recovery plate 5 from being transferred to the lifting structure. The setting of the heat insulation block 11 can enable the exhaust gas to continue to exchange heat with the heat recovery plate 5 when the heat recovery plate 5 exits the heat recovery box 4.

[0023] The lifting structure includes a moving block 15 and a connecting rod 16; a guide groove 17 is provided on one side of the fixed box 9, the connecting rod 16 is located in the guide groove 17, and one end of the connecting rod 16 is fixedly connected to the moving block 15, and the other end of the connecting rod 16 is fixedly connected to the heat recovery plate 5. A motor 13 is provided at the bottom of the fixed box 9, and a screw rod 14 is fixedly connected to the output shaft of the motor 13; the moving block 15 is threadedly connected to the screw rod 14.

[0024] The arrangement of the guide groove 17 and the connecting rod 16 can limit the rotation of the moving block 15 , thereby converting the rotation of the screw rod 14 into the movement of the moving block 15 , and transmitting the movement to the heat recovery plate 5 through the connecting rod 16 .

[0025] The motor 13 is connected to the control cabinet 7 by circuit, and the motor 13 can be automatically controlled by the control cabinet 7 .

[0026] Principle of the utility model

[0027] like Figure 1-2 This is a diagram of the normal use state of the utility model. The control cabinet 7 can control the heating structure 2, thereby controlling the temperature in the furnace body 1, so as to sinter the ceramic. The waste gas generated in the furnace body 1 is discharged into the heat recovery box 4 through the waste gas discharge pipe 3. The heat recovery plate 5 can exchange heat with the heat in the waste gas, thereby introducing the heat in the waste gas into the heat conduction box 6, heating the heat recovery medium in the heat conduction box 6, and the waste gas after heat exchange flows out through the treatment pipe 8 and flows to the next treatment process.

[0028] When the temperature sensor 18 senses that the temperature of the heat recovery medium in the heat transfer box 6 is too high, the control cabinet 7 controls the motor 13 to start. Figure 3-4 As shown, driven by the moving block 15, the heat recovery plate 5 moves downward until it is completely out of the heat recovery box 4, and the heat insulation block 11 is inserted into the card slot 12. At this time, the heat recovery plate 5 can no longer perform heat recovery work, thereby ensuring that no heat enters the heat conduction box 6, and avoiding the heat recovery medium in the heat conduction box 6 from being too high in temperature. Similarly, when the temperature sensor 18 senses that the temperature in the heat conduction box 6 is too low, the motor 13 is controlled to reverse through the control cabinet 7, so that the heat recovery plate 5 can be reinserted into the heat recovery box 4.

[0029] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
