Technical Field

[0001] The utility model relates to the technical field of drying kilns, in particular to an energy-saving drying kiln. Background Art

[0002] Energy-saving drying kiln is a device used to dry wet raw materials or articles. It mainly heats the air and transmits it around the dried articles to accelerate the evaporation of water, so that the raw materials or articles can reach the required degree of dryness. The existing energy-saving drying kiln (Announcement No.: CN219656536U) has the following disadvantages in use:

[0003] During use, the insulating bricks dried in the loading mechanism are pushed out of the loading mechanism to vacate the loading mechanism. In this way, workers are less likely to directly touch hot objects, thereby reducing the possibility of burns. However, during the unloading process, dust on the insulating bricks may be mixed with hot air and diffused in the air, which not only affects the surrounding air quality, but also causes heat waste. For this reason, this patent proposes an energy-saving drying kiln to solve the above problem. Utility Model Content

[0020] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: an energy-saving drying kiln, comprising a drying kiln 1, movable doors 5 are slidably connected on both sides of the drying kiln 1, conveying mechanisms 7 are arranged on both sides of the drying kiln 1, the conveying mechanism 7 comprises mounting members 701 fixed on both sides of the drying kiln 1, the interior of the mounting member 701 is a cavity, a plurality of air suction hoods are fixedly connected to the bottom end of the mounting member 701, a conveying pipe 702 is fixedly connected to the top end of the mounting member 701, a filter box 703 is fixed to the top end of the drying kiln 1, the conveying pipe 702 is fixedly connected to one end of the filter box 703, a filter screen 707 is fixed between the inner walls of both sides of the filter box 703, a fan 704 is fixedly connected to the other end of the filter box 703, an exchanger 706 is installed at one end of the drying kiln 1, an air outlet of the fan 704 is fixedly connected to a connecting pipe 705, and the connecting pipe 705 and the exchanger 706 are fixedly connected.

[0021] It should be noted that when the materials on both sides of the drying kiln 1 begin to be discharged, the fan 704 is used to suck air on both sides of the drying kiln 1 to suck away the hot air mixed with dust during the discharge, and then passes through the filter box 703 and the filter net 707 to filter the hot air. The filtered hot air enters the exchanger 706 through the connecting pipe 705 to achieve heat recovery. In this way, the exchanger 706 can collect heat and use it in other places to realize heat utilization, avoid waste, and prevent dust from spreading in the air and causing harm to the workers.

[0022] like Figure 4As shown, a moving mechanism 6 is provided at both ends of the drying kiln 1, and the moving mechanism 6 includes a mounting frame 601 fixed at both ends of the drying kiln 1, a first screw rod 602 is rotatably connected between the top inner wall and the bottom inner wall of the mounting frame 601, a rotating wheel is rotatably connected to the top of the mounting frame 601, the first screw rod 602 passes through the mounting frame 601 and is fixed to the rotating wheel, a belt is provided between the two rotating wheels, a fixing frame is fixed to the top of one of the mounting frames 601, a first motor is fixed to the top of the fixing frame, an output end of the first motor passes through the fixing frame and is fixed to the rotating wheel, a first slider 603 is screwed to the outer wall of the first screw rod 602, the first slider 603 is slidably connected to the mounting frame 601, connecting rods 604 are fixed on both sides of the first slider 603, and the connecting rods 604 are respectively fixed to the moving doors 5 on both sides of the drying kiln 1.

[0023] It should be noted that the first motor drives the first screw rod 602 to rotate, the first screw rod 602 drives the first slider 603 to move, the movement of the first slider 603 drives the connecting rod 604 to move, and the movement of the connecting rod 604 drives the movable door 5 to move, so that both ends of the drying kiln 1 are opened, so that materials can be added to the drying kiln 1.

[0024] like Figure 1 and Figure 3 As shown, a connecting plate is fixed on both sides of the drying kiln 1, and a first loading box 2 and a second loading box 3 are slidably connected to the connecting plate, and a fixing rod 4 is fixed between the bottom ends of the first loading box 2 and the second loading box 3. A second screw rod 8 is rotatably connected between the inner walls of the two sides of the filter box 703, and a second motor is fixed to one side of the filter box 703. The output end of the second motor passes through the filter box 703 and is fixed to the end of the second screw rod 8. A second slider 9 is screwed to the outer wall of the second screw rod 8, and a scraper 10 is fixed to one end of the second slider 9. The scraper 10 is in contact with the surface of the filter screen 707. A connecting frame is fixed to the bottom end of the filter box 703, and a collection box 11 is inserted in the connecting frame. A controller is installed on the other side of the drying kiln 1, and the controller is electrically connected to the fan 704.

[0025] It should be noted that the second motor drives the second screw rod 8 to rotate, the rotation of the second screw rod 8 drives the second slider 9 to move, the movement of the second slider 9 drives the scraper 10 to move to clean the surface of the filter 707, and the dust that falls after cleaning falls into the collecting box 11 for collection. In addition, by setting the first loading box 2 and the second loading box 3, when the first loading box 2 is loading materials, the materials in the second loading box 3 are dried in the drying kiln 1. This can avoid that there is no work in the drying kiln 1 during the loading process, which affects the drying progress.

[0026] Working principle: when the movable door 5 moves upward, the first loading box 2 and the second loading box 3 move. When the materials on the first loading box 2 or the second loading box 3 are taken out, the fan 704 sucks air on both sides of the drying kiln 1, and sucks away the hot air mixed with dust during the discharge and the hot air flowing out of the drying kiln 1, and then passes through the filter box 703 and the filter net 707 to filter it. The filtered hot air enters the exchanger 706 through the connecting pipe 705 to achieve heat recovery.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
