Description

Technical Field

[0001] This utility model relates to the field of brick blank drying technology, and in particular to a mineral brick blank drying device. Background Technology

[0002] Mineral brick blanks that have not been dried are called wet blanks, and those that have been dried are called dry blanks. Conventionally, hot air is discharged from the vent by fixing the vent. However, because hot air tends to rise, the degree of drying of the same batch of brick blanks can vary greatly.

[0003] In existing technologies, such as the sludge brick blank purification and drying device with patent number CN220417884U, a cover plate is set at the top of the box to concentrate the hot air on the cover plate and blow the hot air onto the brick blank a second time through an induced draft fan, thereby improving the drying efficiency of the brick blank. However, the brick blank contains a large amount of water vapor. Existing technologies do not exhaust the water vapor but blow it directly onto the brick blank, which will form high temperature humidification of the brick blank and affect the drying efficiency. Therefore, there are certain structural defects in existing technologies. Utility Model Content

[0004] The purpose of this invention is to provide a mineral brick blank drying device to solve the problems existing in the prior art and to enhance the drying effect on the brick blanks.

[0025] 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.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Reference Figure 1 This utility model provides a mineral brick blank drying device, comprising:

[0028] Drying oven 1, with a drying rack 2 placed inside the cavity;

[0029] Hot air blower 3, the air outlet of hot air blower 3 is connected to heat insulation pipe 4, and air inlet hood 5 is fixed to one side of drying box 1. Heat insulation pipe 4 is connected to the inner cavity of drying box 1 through air inlet hood 5.

[0030] The exhaust hood 6 is fixed to the outer wall of the drying oven 1 on the side opposite to the air inlet hood 5. The exhaust hood 6 is connected to the inner cavity of the drying oven 1, and an exhaust pipe 7 is connected to the exhaust hood 6.

[0031] The top of the processing box 8 is connected to the air outlet pipe 7. A condenser is provided on the top of the processing box 8. A water collection tank 9 is provided on the bottom of the processing box 8. A guide pipe 10 is connected to the top of the processing box 8 on the side opposite to the air outlet pipe 7. A heating element is provided on the guide pipe 10. The end of the guide pipe 10 away from the processing box 8 is connected to the air inlet of the hot air blower 3.

[0032] This invention uses a hot air blower 3 and an insulation pipe 4 to introduce high-temperature gas into the drying chamber 1, thereby drying the brick blanks placed on the drying rack 2. Simultaneously, as drying progresses, the moisture content in the air inside the drying chamber 1 increases and, along with the hot air, concentrates at the top of the drying chamber 1. The high-temperature, high-humidity gas from the drying chamber 1 is then transported to a processing chamber 8 through an exhaust hood 6. A condenser inside the processing chamber 8 cools the high-temperature, high-humidity gas into low-temperature, dry gas, and the condensed water vapor falls directly into a water collection tank 9 by gravity. The low-temperature, dry gas is then transported to the hot air blower 3 through a guide pipe 10, where it is preheated by a heating element. Combined with the heating effect of the hot air blower 3, the gas used to dry the brick blanks is maintained in a high-temperature, dry state. By promptly discharging the moisture from the drying chamber 1, the drying effect on the brick blanks is enhanced.

[0033] Furthermore, it also includes:

[0034] The top inner wall of the drying box 1 has an integrally formed mounting groove 13. The fan 11 is installed in the mounting groove 13. The air outlet of the fan 11 extends vertically downward. The top of the mounting groove 13 is connected to the air guide pipe 10 through the connecting pipe 12.

[0035] By installing a fan 11 at the top of the drying chamber 1 and blowing air vertically downwards, turbulence is created inside the drying chamber 1, enhancing the uniformity of the drying gas distribution and ensuring the dryness of the brick blanks in each part. Furthermore, the top of the mounting groove 13 is connected to the air guide pipe 10 through the connecting pipe 12, allowing the air inlet of the fan 11 to draw in high-temperature drying gas to create turbulence inside the drying chamber 1, thereby enhancing the stability of the environment inside the drying chamber 1.

[0036] Furthermore, the condenser is a plate cooler 14, which is arranged between the exhaust pipe 7 and the duct pipe 10.

[0037] The gas fed into the processing chamber 8 is cooled by plate cooler 14, thereby condensing and precipitating moisture from the high-temperature, high-humidity gas. (Refer to...) Figure 1 The plate cooler 14 is fixed above the water collection tank 9, and water falls into the water collection tank 9 for collection by gravity.

[0038] Furthermore, a partition 15 is fixedly connected inside the treatment box 8. The partition 15 covers the top of the water collection tank 9. Several water-permeable holes are opened on the partition 15. A water outlet pipe 16 is connected to one side of the bottom of the water collection tank 9. A valve 17 is installed on the water outlet pipe 16.

[0039] Water is collected in the water collection tank 9 through the permeable holes, and finally discharged from the outlet pipe 16 by opening the valve 17.

[0040] Furthermore, it also includes: a first pump 18 and a first check valve 19, which are installed on the air outlet pipe 7, and the air outlet pipe 7 transports gas along the direction from the drying box 1 to the processing box 8;

[0041] The second pump 20 and the second one-way valve 21 are installed on the air guide pipe 10, which transports gas along the direction from the processing box 8 to the hot air blower 3.

[0042] The first pump 18 provides power to transport gas in the outlet pipe 7, and the first one-way valve 19 controls the direction of gas transport to ensure that the high temperature and high humidity gas effectively enters the processing box 8 for drying. Similarly, the second pump 20 provides power to transport gas in the gas guide pipe 10, and the second one-way valve 21 restricts the direction of gas flow in the gas guide pipe 10.

[0043] Furthermore, several through slots are provided on both sides of the inner wall of the drying oven 1, near the air outlet hood 6 and the air inlet hood 5, with both ends of the through slots penetrating the side wall of the drying oven 1.

[0044] By using a through groove to connect the inner cavity of the drying chamber 1 to the exhaust hood 6 and the inlet hood 5 respectively, the gas replacement and circulation are ensured, effectively reducing the removal of water vapor generated during the brick drying process and enhancing the drying effect.

[0045] Furthermore, the heating element includes a sealing tube 22 sleeved on the outside of the air guide tube 10, with a gap between the sealing tube 22 and the air guide tube 10, and an electric heating element 23 fixedly connected in the gap.

[0046] Furthermore, a grille 24 is fixedly connected to the bottom edge of the mounting groove 13.

[0047] This utility model provides a working principle for a mineral brick blank drying device:

[0048] The brick blanks are placed on the drying rack 2 and then into the drying chamber 1. The hot air blower 3 is started to dry the brick blanks. During the process, the moisture in the brick blanks is released with the hot air and accumulates in the drying chamber 1 as high-temperature and high-humidity gas. The high-temperature and high-humidity gas is sent into the processing chamber 8 by starting the first pump 18. The moisture is condensed by the plate cooler 14 and collected in the water collection tank 9. At this time, the valve 17 is kept closed. After the brick blanks are dried, the valve 17 is opened to discharge the moisture. The high-temperature and high-humidity gas is cooled to form low-temperature dry gas. The gas is drawn into the air guide pipe 10 by the second pump 20. During the process, the gas is preheated by the electric heating element 23. Part of the preheated gas is sent into the drying chamber 1 by the fan 11, which creates turbulence for the high-temperature dry gas in the drying chamber 1. The remaining gas is directly drawn into the drying chamber 1 by the hot air blower 3 and heated before being sent into the drying chamber 1. This achieves the circulation of high-temperature dry gas to dry the brick blanks and improves the drying effect.
