Description

Technical Field

[0001] The utility model relates to the technical field of ceramic sintering, in particular to a waste heat recovery device for ceramic sintering. Background Art

[0002] Ceramic sintering is a general term for the densification process and phenomenon of ceramic green body at high temperature. As the temperature rises, the powder particles with large specific surface area and high surface energy in the ceramic green body try to change in the direction of reducing surface energy, continuously undergoing material migration, and the grain boundaries move accordingly. The pores are gradually eliminated, resulting in shrinkage, making the green body a dense porcelain body with a certain strength.

[0003] When ceramics are sintered, a large amount of high-temperature steam will exist in the sintering furnace. If it is discharged directly, the high-temperature heat source inside will be wasted. Under the existing technology, cold water is generally introduced to absorb the heat inside, thereby realizing waste heat recovery during ceramic sintering. However, the waste heat recovery of the existing technology by introducing cold water generally has a short stroke and can only heat a section of cold water. When the temperature in the steam furnace has not reached the maximum value, introducing too much cold water will also lead to insufficient absorption of the heat energy of the cold water. If the cold water introduced is insufficient, there is still a certain amount of heat in the discharged steam, which leads to low waste heat recovery efficiency. At the same time, during waste heat recovery, the temperature in the steam furnace also needs to be paid attention to. For this reason, we propose a waste heat recovery device for ceramic sintering. Utility Model Content

[0007] An adjusting alarm mechanism is provided on one side of the combination steam boiler, and is used to control the water inflow and trigger an alarm when the combination steam boiler is overheated.

[0008] In some embodiments, the combined steam furnace includes a steam furnace body, a steam pipe is provided in the steam furnace body, and the lower end of the steam pipe is communicated with the sintering furnace.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1:

[0025] See also Figure 1-3The utility model provides a technical solution for a waste heat recovery device for ceramic sintering production: a waste heat recovery device for ceramic sintering production, including a sintering furnace 1. The sintering furnace 1 is a prior art, and ceramics are sintered inside it. A large amount of high-temperature steam is generated during sintering. This is a prior art and will not be described in detail here. It also includes: a combined steam furnace 2 arranged above the sintering furnace 1, which absorbs the waste heat of ceramic sintering in the sintering furnace 1 through the combined steam furnace 2; an adjustment alarm mechanism 3 arranged on one side of the combined steam furnace 2, which controls the water intake and triggers an alarm when the combined steam furnace 2 is overheated by adjusting the alarm mechanism 3; the combined steam furnace 2 includes a steam furnace body 21, a steam furnace A steam pipe 22 is provided in the body 21. The material of the steam pipe 22 is copper and has good thermal conductivity. The lower end of the steam pipe 22 is communicated with the sintering furnace 1, and the high-temperature steam in the sintering furnace 1 is discharged to the outside through the steam pipe 22. A water pipe 23 is provided on the outer wall of the steam pipe 22. The end of the water pipe 23 near the bottom is a water inlet 25, and the end of the water pipe 23 near the top is a water outlet 24. The middle end of the water pipe 23 is threaded and wound. Such an arrangement allows the water pipe 23 to cover the outer side of the steam pipe 22 with the maximum area, thereby achieving the maximum efficiency of steam waste heat recovery. The adjustment alarm mechanism 3 includes a fixing bar 31, and a copper rod 32 is provided at one end of the fixing bar 31. , a telescopic tube 33 is provided at one end of the copper rod 32, and gas is provided in the telescopic tube 33. The gas can expand when heated, which is not limited here. This is the prior art. A control valve 34 is provided at the end of the water inlet 25. The control valve 34 can control the water flow at the water inlet 25. The water flow at the water inlet 25 can be increased by pulling up the control end; the fixing bar 31 is fixedly arranged above the sintering furnace 1, and the copper rod 32 passes through the side wall of the steam furnace body 21. The copper rod 32 can quickly transfer the temperature in the steam furnace body 21 to the telescopic tube 33; one end of the telescopic tube 33 is fixedly arranged on the fixing bar 31, and the other end of the copper rod 32 is connected to the telescopic tube 33; the control valve 34 A magnetic block 38 is fixedly provided on the outer wall of the water inlet 25, and a movable block 36 is fixedly provided on the upper end of the control valve 34. The movable block 36 is made of magnetic material. When the movable block 36 moves, the magnetic block 38 is adsorbed and moves with it. When the movable block 36 continues to move upward until the two are separated, the movable block 36 will continue to adsorb the magnetic block 38. By setting the water pipe 23 and the adjustment alarm mechanism 3, the water flow in the water pipe 23 is related to the temperature in the steam boiler body 21. When the temperature rises, the water flow in the water pipe 23 increases. When the temperature continues to rise and exceeds the critical value, the alarm 35 is triggered to work and a buzzer alarm is issued.

[0026] When the sintering furnace 1 begins the ceramic sintering operation, a large amount of steam is released from the steam pipe 22 as the sintering process continues. The steam pipe 22 is made of copper and has excellent thermal conductivity. At this time, water begins to flow into the water pipe 23 through the water inlet 25. Under the action of pressure, the water flows upward around the water pipe 23 and then flows out from the water outlet 24. In the process, it is heated by the steam pipe 22. When the temperature in the steam furnace body 21 increases, the copper rod 32 transfers the temperature to the telescopic tube 33. The gas in the telescopic tube 33 expands due to the heat, and the telescopic tube 33 moves upward, pushing the movable block 36. Since the movable block 36 is made of magnetic material, one end of the movable block 36 drives the magnetic block 38 at the control end of the control valve 34. As the magnetic block 38 continues to move upward, the control end of the control valve 34 is gradually opened. At this time, the water flow at the water inlet 25 gradually increases, and the water flow in the water pipe 23 also gradually increases, thereby optimizing the heat recovery in the steam furnace body 21.

An alarm 35 is provided above the control valve 34, and the alarm 35 will emit a buzzer alarm when the control button 37 is pressed. When the alarm is issued, it means that the temperature in the steam furnace body 21 exceeds the set critical value. At this time, when the staff hears the alarm 35 triggered, they will check the specific conditions in the sintering furnace 1 and the steam furnace body 21.

[0029] By arranging the copper rod 32, telescopic tube 33, movable block 36, control valve 34, alarm 35, control button 37 and magnetic block 38, when the temperature inside the steam oven body 21 rises, the temperature is transferred to the telescopic tube 33 through the copper rod 32. The expansion of the telescopic tube 33 drives the movable block 36 to move, thereby gradually opening the control valve 34. When the movable block 36 touches the control button 37, the alarm 35 sounds an alarm.
