[0002] Green tiles are an environmentally friendly, healthy and sustainable building decoration material. They use recycled materials, environmentally friendly materials and recyclable materials. During the manufacturing process of tiles, the manufactured tile blanks need to be dried to remove moisture in the tile blanks, making the tiles harder, and improving their strength and hardness, thereby reducing the risk of deformation and cracking during subsequent processing and use. However, the existing tile drying towers directly discharge the hot air after drying the tile blanks, and are unable to reuse the remaining heat, thereby reducing the utilization rate of heat and energy. Utility Model Content

[0003] The purpose of the utility model is to provide a green and environmentally friendly dust removal device for tile production with a waste heat recovery structure to solve the problem in the above-mentioned background technology that the exhausted hot air cannot be reused.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a green and environmentally friendly dust removal device for ceramic tile production equipped with a waste heat recovery structure, comprising a box body, an opening and closing door is rotatably installed on the side surface of one end of the box body, and the outer surface of the opening and closing door is inlaid and fixedly installed with organic heat-resistant glass, an exhaust duct is fixedly installed on the side surface of one end of the box body, and a mounting hole is provided at one end of the exhaust duct, an air intake fan is fixedly installed inside the box body, and the air intake fan is located at one end of the box body away from the exhaust duct, and the outer surface of the exhaust duct is covered with thermal insulation material, a circulation recovery structure is provided between the box body and the exhaust duct, and the heat of the exhausted hot air is reused through the circulation recovery structure.

[0005] Preferably, a heat-absorbing coiled pipe is fixedly installed inside the exhaust duct, a circulation pump is fixedly installed on the outer surface of the box body, and one end of the circulation pump is connected to one end of the heat-absorbing coiled pipe, a heat-releasing fin is fixedly installed inside the end of the box body close to the air intake fan, and one end of the heat-releasing fin is connected to the circulation pump, and the heat-absorbing coiled pipe is connected to the heat-releasing fin.

[0006] Using the above technical solution, the device blows hot air toward the tiles through the air intake fan for drying, and then the hot air is discharged outward through the exhaust duct. The discharged hot air heats the heat-absorbing winding pipe and pumps the medium through the circulation pump, so that the heated medium can enter the heat-releasing fins and release heat outward, thereby improving the efficiency of drying the tile blanks and reducing the energy consumption of the electric heating plate, so that the discharged heat energy can be reused.

[0007] Preferably, a rotating locking pin is rotatably installed on the side surface of the opening and closing door, and the rotating locking pin is engaged with the outer surface of the box body. The outer surface of the box body is fixedly installed with a heat-absorbing wrapped pipe and a pipe connecting the heat-releasing fins, and the outer surface of the pipe between the heat-absorbing wrapped pipe and the heat-releasing fins is covered with insulation material.

[0008] By adopting the above technical solution, the box body and the opening and closing door can be fixed to each other and kept closed by rotating the locking pin, and the heat insulation material can maintain the heat preservation of the pipe between the heat-absorbing wrapped pipe and the heat-releasing fins, thereby reducing the loss of medium temperature.

[0009] Preferably, an electric heater is fixedly mounted on one end of the box body close to the air intake fan, and heat dissipation fins are arranged between the electric heater and the air intake fan. A filter is fixedly mounted on the side surface of one end of the box body away from the exhaust duct.

[0010] By adopting the above technical solution, the electric heating plate provides heat for drying, and the setting of the intake fan, electric heating plate and heat release fins can reduce the generation of condensed water on the heat release fins. The air drawn by the intake fan can be filtered through the filter net to prevent external dust from being sucked into the box and causing blockage of the electric heating plate and the heat release fins.

[0011] Preferably, protective plates are fixedly installed on the inner surfaces of both sides of the box body near the opening and closing door, and the outer surfaces of the protective plates are evenly provided with through holes, and the outer surfaces of the protective plates do not fit the outer surfaces of the heating plate and the heat-absorbing wrapped pipe.

[0012] By adopting the above technical solution, the protective plate can protect the electric heating plates and the heat-absorbing wrapped pipes on both sides of the box body, and allow the hot air to be discharged outward through the through holes where the bracket is placed.

[0013] Preferably, the bottom of the exhaust duct is designed to be inclined, and a drainage duct is provided on the outer surface of the exhaust duct, and the drainage duct is located at the lowest point of the exhaust duct.

[0014] By adopting the above technical solution, when the medium circulates in the heat-absorbing wrapped pipe, the heat-absorbing wrapped pipe is heated, and condensation water will be generated on the outer surface of the heat-absorbing wrapped pipe.

[0015] Preferably, a placement bracket is installed inside the box, and the outer surface of the placement bracket is in contact with the outer surface of the box, and the outer surface of the box is in contact with the outer surface of the placement bracket. A grid slide is slidably installed inside the placement bracket, and ceramic tile blanks are placed on the outer surface of the grid slide.

[0016] By adopting the above technical solution, the ceramic tile blanks can be conveniently placed on the outer surface of the grid slide, and then the grid slide can be pushed into the placement bracket, which makes it convenient to load and unload the ceramic tile blanks. The air-dried ceramic tile blanks can also be conveniently pulled out of the box and transported to the next process location.

[0017] Compared with the prior art, the beneficial effects of the present invention are: the green and environmentally friendly dust removal device for tile production with a waste heat recovery structure:

[0018] 1. When the device is started, hot air will pass through the box and dry the ceramic tiles. The hot air will then be discharged outwards through the exhaust duct. As the hot air is discharged, it will heat the heat-absorbing coiled pipe and the medium in the heat-absorbing coiled pipe. The heated medium is then pumped into the heat-releasing fins through the circulation pump, so that the heat-releasing fins can release heat and the heat is heated and sent out through the intake fan, which reduces the heating time of the electric heater and improves the drying efficiency, so that the waste heat of the discharged hot air can be reused.

[0019] 2. As the electric heater heats up and the air intake fan blows, the air is heated and blown toward the ceramic tile blanks. The air drawn in is filtered through a filter to prevent dust in the air from clogging the electric heater and the heat release fins, thereby reducing the heat release efficiency. The position of the air intake fan, electric heater, and heat release fins is set so that when the drying tower is started, the hot air will not pass through the heat release fins to generate condensed water, and dust will not enter the box, causing the heat to be unable to be released quickly and the ventilation volume to decrease.

[0020] 3. When placing ceramic tiles, you only need to pull the grid slide out of the placement bracket, and you can easily place the tiles on the outer surface of the grid slide. After placement, push the grid slide back into the placement bracket to conveniently place and unload the ceramic tiles. Laying the ceramic tiles flat allows hot air to quickly pass through the box without being blocked, thereby accelerating the drying of the ceramic tiles. After the ceramic tiles are dried, the placement bracket can be pulled out of the box as a whole, making it convenient to take out all the ceramic tiles from the box at once and to send all the ceramic tiles to the next process.

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.

[0029] See also Figure 1-6 The utility model provides a technical solution: a green and environmentally friendly dust removal device for ceramic tile production with a waste heat recovery structure, comprising a box body 1, an opening and closing door 2 is rotatably installed on the side surface of one end of the box body 1, and the outer surface of the opening and closing door 2 is inlaid and fixedly installed with organic heat-resistant glass 4, an exhaust duct 3 is fixedly installed on the side surface of one end of the box body 1, and a mounting hole is opened at one end of the exhaust duct 3, an intake fan 7 is fixedly installed inside the box body 1, and the intake fan 7 is located at the end of the box body 1 away from the exhaust duct 3, and the outer surface of the exhaust duct 3 is covered with thermal insulation material, a circulation recovery structure is provided between the box body 1 and the exhaust duct 3, and the heat of the exhausted hot air is reused through the circulation recovery structure.

[0030] The status of the ceramic tiles inside the box 1 can be checked at any time through the organic heat-resistant glass 4. The length of the exhaust duct 3 can be extended through the installation hole of the exhaust duct 3. The thermal insulation of the exhaust duct 3 can be improved by the material covering the outer surface of the exhaust duct 3, so that the heat-absorbing wrapped duct 10 can be better heated.

[0031] A heat-absorbing coiled pipe 10 is fixedly installed inside the exhaust duct 3, a circulation pump 6 is fixedly installed on the outer surface of the box body 1, and one end of the circulation pump 6 is connected to one end of the heat-absorbing coiled pipe 10, a heat-releasing fin 11 is fixedly installed inside the end of the box body 1 close to the air intake fan 7, and one end of the heat-releasing fin 11 is connected to the circulation pump 6, and the heat-absorbing coiled pipe 10 is connected to the heat-releasing fin 11.

[0032] As the air intake fan 7 rotates, the external air is drawn into the interior of the box 1, and is blown toward the ceramic tile blank after being heated by the electric heating plate 8. The moisture inside the ceramic tile blank is taken away by the hot air that passes through. The hot air is then discharged to the outside from the exhaust duct 3 and heats the medium inside the heat-absorbing winding pipe 10. The medium is circulated between the heat-absorbing winding pipe 10 and the heat-releasing fins 11 by the pumping of the circulation pump 6, and the heated medium is allowed to release heat in the heat-releasing fins 11, so that the waste heat discharged from the drying can be utilized, thereby improving the drying efficiency of the ceramic tile and reducing the heating time of the electric heating plate 8.

[0033] A rotating locking pin 5 is rotatably installed on the side surface of the opening and closing door 2, and the rotating locking pin 5 is engaged with the outer surface of the box body 1.

[0035] An electric heater 8 is fixedly mounted on one end of the housing 1 near the air intake fan 7 , and a heat dissipation fin 11 is provided between the electric heater 8 and the air intake fan 7 . A filter 14 is fixedly mounted on the side surface of one end of the housing 1 away from the exhaust duct 3 .

[0037] Protective plates 9 are fixedly installed on the inner surfaces of both sides of the box body 1 near the opening and closing door 2, and the outer surfaces of the protective plates 9 are evenly provided with through holes. The outer surfaces of the protective plates 9 do not fit the outer surfaces of the electric heating plate 8 and the heat-absorbing wrapped pipe 10.

[0038] The protective plate 9 protects the electric heating plate 8 and the heat-absorbing wrapped pipe 10, reducing the probability of damage caused by objects falling, hitting or contacting the electric heating plate 8 and the heat-absorbing wrapped pipe 10.

[0039] The bottom of the exhaust duct 3 is designed to be inclined, and a drainage duct 13 is opened on the outer surface of the exhaust duct 3 , and the drainage duct 13 is located at the lowest point of the exhaust duct 3 .

[0040] When the exhausted hot air heats the heat-absorbing wrapped pipe 10 , the heat-absorbing wrapped pipe 10 absorbs heat to generate condensed water, and the condensed water is discharged to the outside from the drainage pipe 13 along the inclined surface at the bottom of the exhaust pipe 3 .

[0041] A placement bracket 15 is installed inside the box 1, and the outer surface of the placement bracket 15 is in contact with the outer surface of the box 1. A grid slide 16 is slidably installed inside the placement bracket 15, and ceramic tiles are placed on the outer surface of the grid slide 16.

[0042] When loading and unloading, you only need to pull out the grid slide 16 from the placement bracket 15, and you can easily place the tile blanks on the outer surface of the grid slide 16. Then you can push the grid slide 16 back to its original position, which is convenient for loading and unloading. The tiles are placed flat, which allows the hot air to smoothly accelerate through the box 1 to quickly take away the moisture of the tile blanks. After the tile blanks are dried, the placement bracket 15 can be directly pulled out of the box 1, all the tile blanks can be taken out of the box 1 at one time, and the placement bracket 15 can be conveniently transferred to the unloading point.
