Description

Technical Field

[0001] This utility model relates to the field of hollow brick sintering technology, and in particular to a lightweight pressure-resistant hollow brick sintering device. Background Technology

[0002] This device is a sintering equipment specially designed for lightweight, pressure-resistant hollow bricks. It integrates precise temperature control, uniform material distribution, and efficient firing modules. By optimizing the furnace structure and thermal circulation system, it achieves low-temperature rapid sintering, reducing energy consumption while ensuring uniform pore size and strength within the brick. It is easy to operate, highly adaptable, and can stably produce lightweight, high-strength, sound-insulating, and heat-insulating hollow bricks, meeting the energy-saving requirements of buildings.

[0003] Traditional sintering equipment lacks an efficient temperature circulation mechanism, resulting in scattered heat distribution within the chamber and significant differences in the heating of the brick blanks. This can easily lead to problems such as localized over-firing and under-firing. Traditional sintering equipment also lacks a complete smoke purification and waste heat recovery device, resulting in the direct emission of sintering fumes. The fine dust and other impurities contained in these fumes pollute the air, violating environmental standards. A large amount of waste heat in the high-temperature flue gas is directly lost and cannot be recovered and reused, causing serious energy waste, increasing the energy consumption costs of enterprises, and exacerbating environmental pollution.

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1-4 This utility model provides a lightweight pressure-resistant hollow brick sintering device, which includes a base 4, a box 3 fixedly connected to the upper end of the base 4, a smoke collection hood 8 fixedly connected to the upper end of the box 3, a smoke exhaust pipe 2 fixedly connected to one side of the smoke collection hood 8, an annular pipe 9 fixedly connected to the outside of the smoke exhaust pipe 2, a partition net 1 fixedly connected to the inside of one end of the smoke exhaust pipe 2, and a first pipe 14 fixedly connected to the lower end of the annular pipe 9, with the inside of the annular pipe 9 communicating with one end of the first pipe 14.

[0024] Specifically, the base 4 is the supporting foundation of the device, the box 3 provides a closed high-temperature sintering environment, the fume hood 8 collects the smoke generated during sintering inside the box 3 to prevent the smoke from spreading, and centrally introduces it into the exhaust pipe 2. The exhaust pipe 2 guides the smoke collected by the fume hood 8 to the direction of subsequent treatment and emission. The annular pipe 9 is fixed around the outside of the exhaust pipe 2. The high temperature of the outer wall of the exhaust pipe 2 is used to heat the internal air to achieve waste heat recovery. The heated high-temperature air is then introduced into the lower first pipe 14. The mesh 1 can prevent foreign objects from entering the pipe. The first pipe 14 receives the high-temperature air transported by the annular pipe 9 and connects downward to the second pipe 20 to form a high-temperature air guiding channel.

[0025] An air inlet 21 is provided on one side of the annular pipe 9, and a filter screen 12 is fixedly connected inside the air inlet 21.

[0026] Specifically, the air inlet 21 provides an air inlet for the annular pipe 9, and the filter screen 12 filters out air impurities entering the annular pipe 9.

[0027] A No. 1 fan 10 is installed at the lower end of the partition net 1, and a filter body 11 is installed at the lower end of the No. 1 fan 10. One end of the smoke exhaust pipe 2 is connected to the inside of the smoke collection hood 8.

[0028] Specifically, fan 10 provides suction power to accelerate the flow of smoke in exhaust duct 2, thereby increasing the exhaust speed. Filter 11 performs fine filtration of the smoke, further removing small impurities and purifying the exhaust.

[0029] The base 4 has a second pipe 20 fixedly connected inside, the second pipe 20 has a second fan 15 fixedly connected inside, and multiple through holes 16 are opened between the second pipe 20 and the box 3. The upper end of the second pipe 20 is fixedly connected to the first pipe 14.

[0030] Specifically, the second pipe 20 is located inside the base 4 and is the lower channel for high-temperature air circulation. It connects the first pipe 14 and the box 3. The second fan 15 is installed inside the second pipe 20 to provide airflow power and accelerate the flow of high-temperature air from the first pipe 14 into the second pipe 20, and then guides it to the box 3. Multiple through holes 16 are evenly distributed to allow high-temperature air to enter the box 3 evenly, which helps to raise or maintain the temperature inside the box 3.

[0031] The box body 3 has two symmetrical sliding grooves 17 inside, and a movable plate 18 is slidably connected inside the sliding grooves 17. Multiple through grooves 19 are opened inside the movable plate 18, and a second pulley 13 is symmetrically installed at the lower end of the movable plate 18.

[0032] Specifically, the chute 17 provides a sliding track for the moving plate 18, limiting the direction of movement. The moving plate 18 holds the hollow brick blanks to be sintered and can slide along the chute 17, facilitating the placement and removal of the brick blanks. Multiple through slots 19 penetrate the moving plate 18, ensuring that the high-temperature air and heat inside the box 3 can penetrate the moving plate 18 and act evenly on all the brick blanks, avoiding uneven sintering in certain areas. The second pulley 13 can reduce the friction between the moving plate 18 and the chute 17.

[0033] A fitting groove 7 is provided on one side of the box body 3, and a box door 5 is movably fitted inside the fitting groove 7.

[0034] Specifically, the fitting groove 7 provides installation positioning for the box door 5, ensuring that the box door 5 fits tightly with the box body 3. The box door 5 is movably fitted into the fitting groove 7, sealing the box body 3 when closed to prevent heat loss and smoke leakage, and facilitating the loading and unloading of the movable plate 18 and brick blanks when opened.

[0035] Multiple pulleys 6 are fixedly connected to the upper end of the base 4, and the upper end of the pulleys 6 is in close contact with the door 5.

[0036] Specifically, pulley 6 is fixed to the upper part of base 4, and multiple pulleys are evenly distributed to support the weight of box door 5.

[0037] Working principle: The hollow brick blank to be sintered is placed on the movable plate 18 with a through groove 19. The movable plate 18 slides along the sliding groove 17 inside the box body 3. After being pushed into the box body 3, the box door 5 in the fitting groove 7 is closed. The first pulley 6 supports the box door 5 and ensures a seal, so that the box body 3 forms a closed high-temperature sintering environment. The smoke generated during the sintering process is collected by the smoke collection hood 8 and enters the smoke exhaust pipe 2 under the suction of the first fan 10. After being finely filtered by the filter body 11, it is discharged. The high temperature of the outer wall of the smoke exhaust pipe 2 heats the air inside the annular pipe 9 surrounding it, achieving... Waste heat recovery: external air enters the annular pipe 9 after being filtered by the filter screen 12 of the air inlet 21. The second fan 15 provides power to guide the high-temperature air in the annular pipe 9 into the second pipe 20 in the base 4 through the first pipe 14, and then evenly into the box 3 through multiple through holes 16. The high-temperature air passes through the through slot 19 of the moving plate 18 and penetrates all the brick blanks, helping to maintain the temperature balance in the box 3 and avoid uneven sintering. This completes the continuous working process of sintering, smoke filtration, waste heat recovery and high-temperature circulation, which not only improves the sintering effect, but also realizes energy recovery and smoke purification.

[0038] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
