Description

Technical Field

[0001] The utility model relates to the technical field of unburned brick drying, in particular to an unburned brick drying device. Background Art

[0002] Unburned bricks are a new type of wall material made from fly ash, coal cinder, coal gangue, tailings slag, chemical slag or natural sand, sea mud, etc. (one or more of the above raw materials) as the main raw materials without high-temperature calcination. In the production process of unburned bricks, the unburned bricks need to be dried after demoulding to remove some of the moisture and shape them.

[0003] The relevant Chinese patent publication number is CN213514706U, which discloses a device for drying unfired bricks. The unfired bricks on the tray are pushed to four groups of nozzles by an electric push rod for drying. A through hole is opened in the middle of the upper end of the heating box, which is connected to the return pipe through a return pipe. The hot air on the heating box can be collected in the return pipe for recycling, which is conducive to more practical use of unfired bricks.

[0004] Although the unfired brick drying equipment in the above-mentioned prior art can dry the unfired bricks and collect the waste heat for reuse to achieve the purpose of energy saving, in actual use, part of the water vapor in the unfired bricks evaporates after being heated when the unfired bricks are dried. The evaporated water vapor remains inside the equipment. If the heat is directly utilized, the humidity inside the equipment is likely to be too high, affecting the drying effect of the unfired bricks that subsequently enter the shell. For this reason, we propose a unfired brick dryer. Utility Model Content

[0008] In a further technical solution, the metal air ducts are densely distributed at equal intervals on the top of the shell, and the top ends of the metal air ducts penetrate the top of the shell and the waste heat recovery box.

[0009] In a further technical solution, the right side of the waste heat recovery box is fixedly connected to a connecting pipe, the connecting pipe is fixedly connected to the left side of the heating box, and the right end of the connecting pipe passes through the left side of the heating box.

[0010] In a further technical solution, a dry pipe is provided on the right side of the heating box, and the bottom end of the dry pipe passes through the right side of the shell and extends into the interior of the shell.

[0011] In a further technical solution, a branch pipe is fixedly connected to the front side of the main pipe, and the branch pipe is fixedly connected to the rear side of the diversion box and extends into the interior of the diversion box.

[0025] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

[0026] Example:

[0027] like Figure 1-Figure 5 As shown, a dryer for unfired bricks includes a shell 1, a scraper assembly 5 is fixedly connected to the inner side of the shell 1, a drying mechanism 3 is fixedly connected to the top of the shell 1, a conveyor belt 2 for transporting bricks is arranged inside the shell 1, and a transparent window 4 is arranged on the front side of the shell 1.

[0028] The drying mechanism 3 includes a waste heat recovery box 301, which is fixedly connected to the top of the shell 1. A fan 307 is fixedly connected to the left side of the waste heat recovery box 301. A metal air duct 302 is fixedly connected to the top of the shell 1. A heating box 303 is fixedly connected to the top of the shell 1. A heater 308 is fixedly connected to the inside of the heating box 303. A diverter box 305 is arranged on the inside of the shell 1. Two diverter boxes 305 are arranged. The two diverter boxes 305 are symmetrically distributed on both sides of the upper conveyor belt 2.

[0029] The working principle of the above technical solution is as follows:

[0030] The unburned bricks to be dried are placed on the conveyor belt 2, and are brought into the shell 1 by the action of the conveyor belt 2. The air is driven into the heating box 303 by the action of the fan 307, and the air is heated by the action of the heater 308. The heated air enters the two diversion boxes 305 through the main pipe 304 and the branch pipe 309. The hot air in the two diversion boxes 305 is discharged through the air outlet 310, and the unburned bricks are dried from two sides. The heat generated during drying is discharged to the outside of the shell 1 through the metal air duct 302. The air entering the waste heat recovery box 301 is heated by the metal air duct 302, thereby preheating the air entering the heating box 303 to achieve energy saving.

[0031] In another embodiment, if Figure 2 As shown, the metal air ducts 302 are densely distributed at equal intervals on the top of the shell 1 , and the tops of the metal air ducts 302 penetrate the top of the shell 1 and the waste heat recovery box 301 .

[0032] The water vapor and hot air above the shell 1 can be discharged to the outside of the shell 1 under the action of the metal air duct 302, and the air in the waste heat recovery box 301 can be heated during the discharge process.

[0033] In another embodiment, if Figure 2 As shown, the right side of the waste heat recovery box 301 is fixedly connected to the connecting pipe 306 , the connecting pipe 306 is fixedly connected to the left side of the heating box 303 , and the right end of the connecting pipe 306 passes through the left side of the heating box 303 .

[0034] Under the action of the connecting pipe 306 , the air in the waste heat recovery box 301 can enter the heating box 303 through the connecting pipe 306 , so as to heat the air entering the shell 1 .

[0035] In another embodiment, if Figure 2 As shown, a dry pipe 304 is provided on the right side of the heating box 303 , and the bottom end of the dry pipe 304 passes through the right side of the shell 1 and extends into the interior of the shell 1 .

[0036] Under the action of the dry pipe 304 , the heated air can pass through it and enter the interior of the shell 1 , thereby heating the unfired bricks inside the shell 1 .

[0037] In another embodiment, if Figure 5 As shown, a branch pipe 309 is fixedly connected to the front side of the main pipe 304 , and the branch pipe 309 is fixedly connected to the rear side of the diverter box 305 and extends into the interior of the diverter box 305 .

[0038] The branch pipe 309 facilitates the hot air in the main pipe 304 to enter the diverter box 305, so that the passing unfired bricks are heated and dried through the diverter box 305.

[0039] In another embodiment, if Figure 5 As shown, air outlet holes 310 are provided on opposite surfaces of the two diverter boxes 305 , and the air outlet holes 310 are densely distributed at equal intervals on the outside of the diverter boxes 305 .

[0040] The air outlet holes 310 facilitate the discharge of hot air from the diversion box 305, and the unfired bricks are dried from different positions under the effect of the dense distribution with equal spacing, which helps to improve the drying effect.

[0041] In another embodiment, if Figure 2 As shown, the scraper assembly 5 includes a cleaning brush 502, which is fixedly connected to the inner side of the shell 1. A collecting groove 501 is provided at the bottom of the shell 1, and a placement groove 503 is provided on the front side of the shell 1. The bottom of the collecting groove 501 is connected to the inside of the placement groove 503, and a collecting box 504 is provided inside the placement groove 503.

[0042] The cleaning brush 502 can clean the unburned brick residue on the conveyor belt 2, and the cleaned residue enters the collecting trough 501, and enters the collecting box 504 below for collection under the action of the collecting trough 501, thereby ensuring the efficiency of hot air passing through and reducing the friction of the equipment during operation.

[0043] The above embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
