Description

Technical Field

[0001] This utility model relates to the field of grate cooler technology, specifically an energy-saving and environmentally friendly grate cooler that can switch between cold air cooling and natural air cooling. Background Technology

[0002] The grate cooler is a key piece of equipment in cement production used to cool clinker discharged from the rotary kiln. It rapidly reduces the clinker temperature through the reciprocating motion of the grate and the penetration of cooling air, thereby improving clinker quality and production efficiency. The design of a grate cooler typically includes movable and fixed grate plates, as well as mechanisms for conveying clinker and controlling the flow of cooling air. The grate cooler not only improves the cooling efficiency of the clinker but also enhances the energy efficiency of the entire production process by recovering the heat generated during cooling.

[0003] According to announcement number CN212409408U, an energy-saving and environmentally friendly grate cooler is disclosed. This patent includes a grate cooler housing, with an inlet at one end. A grate cooling plate is located within the housing's inner cavity. An air-cooling hood is positioned below the grate cooling plate and fixed to it. Ventilation holes are provided on the air-cooling plate. A filter screen is positioned between the air-cooling hood and the air-cooling plate. A baffle is located on the side of the air-cooling hood, and a connecting block is located on the side of the air-cooling plate. The connecting block extends out of the grate cooler housing, and a heat sink is located at its end. An outlet is located at the other end of the grate cooler housing. The filter screen between the air-cooling hood and the air-cooling plate filters out fine dust, preventing it from entering the surrounding air. Simultaneously, the heat sink dissipates excess heat, reducing the burden on the air-cooling system and thus reducing energy consumption.

[0004] However, during the use of the aforementioned patent, when cooling the clinker on the grate cooling plate, the cold air is continuously input, making it difficult to switch the air type, which leads to a large overall energy consumption of the grate cooler; moreover, the exhaust air is discharged directly into the atmosphere without filtration, which can easily cause environmental pollution and thus affect the use of the grate cooler.

[0026] Please see Figures 1-5 This utility model provides a technical solution: an energy-saving and environmentally friendly grate cooler that can switch between cold air cooling and natural air cooling, including a base 1, a grate cooler body 2, and a feed hopper 3.

A grate cooling plate 4 is installed inside the grate cooler body 2, and a discharge hopper 5 is connected to the side of the grate cooler body 2 away from the feed hopper 3. An auxiliary mechanism 6 is provided above the grate cooling plate 4, and the auxiliary mechanism 6 includes an exhaust fan 601, an exhaust pipe 602, a cooler 603, a conveying pipe 604, a booster pump 605, an air inlet pipe 606, and an air outlet pipe. The system includes a pipe 607, a filter box 608, an air pump 609, an exhaust pipe 610, a drive motor 611, a rotating column 612, an eccentric plate 613, a filter screen 614, a fixed base 615, and a spring 616. An exhaust fan 601 is installed at the top center of the main body 2 of the grate cooler. An exhaust pipe 602 is connected to the input end of the exhaust fan 601, and a cooler 603 is connected to the middle of the outer wall of the exhaust pipe 602. Conveying pipes 604 are connected to both sides of the outer wall of the exhaust fan 601, and a booster pump 605 is connected to the side of the conveying pipe 604 away from the exhaust fan 601. An air inlet pipe is connected to the output end of the booster pump 605. 606. An air outlet duct 607 is installed on the top of the main body 2 of the grate cooler, near the discharge hopper 5. A filter box 608 is connected to the top of the air outlet duct 607, and an air pump 609 is connected to the outer wall of the filter box 608 on the side away from the booster pump 605. An exhaust duct 610 is connected to the output end of the air pump 609. A drive motor 611 is installed in the middle of the outer wall of the filter box 608. A rotating column 612 is connected to the output end of the drive motor 611, and eccentric plates 613 are welded to both sides of the outer wall of the rotating column 612. A filter screen plate 614 is connected to the outer wall of the eccentric plate 613 through pulleys, and the upper and lower sides of the filter screen plate 614 are slidably connected internally. There is a fixed base 615; one side of the outer wall of the fixed base 615 is welded to the inner wall of the filter box 608, and a spring 616 is connected inside the fixed base 615; the filter screen plate 614, the fixed base 615 and the spring 616 form an elastic telescopic mechanism; the bottom end of the filter box 608 is connected to the top of the grate cooler body 2; the bottom end of the air cooler 603 is connected to the top of the grate cooler body 2; the bottom end of the booster pump 605 is connected to the top of the grate cooler body 2; the air outlet of the air inlet pipe 606 faces the grate cooler plate 4; one side of the outer wall of the spring 616 is fixedly connected to the filter screen plate 614; the pulley and the filter screen plate 614 are connected by a rolling connection.

[0027] In practical implementation, during the use of this grate cooler, in order to reduce energy consumption, the exhaust fan 601 is first started to draw in outside air through the exhaust duct 602. Then, the air cooler 603 is started to generate cold air. Since the air cooler 603 is connected to the exhaust duct 602, the cold air generated by the air cooler 603 will be drawn away by the exhaust fan 601. Then, the cold air is directed to the booster pump 605 through the delivery duct 604. The booster pump 605 is then started to pressurize the cold air, and finally, the cold air is discharged through the outlet duct 607. The air is sprayed onto the cooling grate plate 4, thereby cooling the high-temperature clinker on the cooling grate plate 4 with cold air. When the temperature of the high-temperature clinker on the cooling grate plate 4 reaches the set value, the air cooler 603 is turned off. At this time, the exhaust fan 601 can only draw natural air. After the above operation, the natural air is blown onto the cooling grate plate 4, thereby cooling the high-temperature clinker on the cooling grate plate 4 with natural air. This realizes the switching between cold air cooling and natural air cooling, eliminating the need to use cold air cooling continuously, thus reducing energy consumption without affecting cooling efficiency and quality.

[0028] When cold air and natural wind blow over the high-temperature clinker on the grate cooling plate 4 and then discharge it through the air outlet duct 607 from the main body 2 of the grate cooler, the exhaust gas first enters the filter box 608 because the air outlet duct 607 is connected to the filter box 608. Then, the air pump 609 is started to generate suction, which causes the exhaust gas to pass through the filter screen 614. At this time, the dust carried by the gas is filtered through the filter screen 614 to prevent the clinker dust carried by the cold air from being directly discharged when passing through the clinker layer. Then, it is discharged through the exhaust pipe 610, thereby preventing the clinker dust from being directly discharged into the outside world and causing environmental pollution.

[0029] As the filter screen 614 becomes clogged with dust over time, causing a decrease in filtration efficiency, the drive motor 611 is first started to rotate the rotating column 612. Then, the rotating column 612 rotates, causing the eccentric plate 613 to rotate until the pulley on the outer wall of the eccentric plate 613 contacts the filter screen 614, thereby generating a pushing force on the filter screen 614. This causes the filter screen 614 to move closer to the air pump 609. The movement of the filter screen 614 will compress the spring 616, causing it to deform. Afterward, as the eccentric plate 613 rotates and disengages from the filter screen 614, the spring 616 will return to its original position and generate elastic force. This causes the filter screen 614 to repeatedly collide with the fixed base 615, thereby shaking off the dust that is clogging the filter screen 614 and preventing it from clogging the filter screen 614 and causing a decrease in filtration efficiency. Thus, when using the grate cooler, it helps to reduce energy consumption and filter dust.

[0030] See Figure 1 , Figure 6 and Figure 7It is known that the outer wall of the main body 2 of the grate cooler is provided with a guide mechanism 7, and the guide mechanism 7 includes an electric push rod 701, a lifting seat 702, a fixed column 703, a transmission column 704 and a moving wheel 705. The electric push rod 701 is installed on both sides of the top of the base 1. The output end of the electric push rod 701 is connected to the lifting seat 702, and the fixed column 703 is slidably connected inside the lifting seat 702. The lifting seat 702 is in the shape of a "Z". The transmission column 704 is welded to the bottom of the lifting seat 702, and the moving wheel 705 is connected to the bottom of the transmission column 704. The transmission column 704 is slidably connected to the base 1. The lifting seat 702 is symmetrically distributed about the vertical midline of the base 1. The bottom of the fixed column 703 is welded to the top surface of the base 1.

[0031] In practical implementation, during the use of the grate cooler, if the main body 2 of the grate cooler needs to be moved for equipment layout and general cleaning, the electric push rod 701 on the base 1 is first activated. Since the output end of the electric push rod 701 is connected to the lifting seat 702, the retraction of the electric push rod 701 will drive the lifting seat 702 to move downward. Then, the downward movement of the lifting seat 702 will drive the transmission column 704 to move downward together. Furthermore, the downward movement of the transmission column 704 will drive the moving wheel 705 to move downward. Since the lifting seat 702 and the fixed column 703 are slidably connected, the movement of the lifting seat 702 is guided by the fixed column 703, thus allowing the lifting seat 702 to move downward. The lowering seat 702 moves smoothly until the moving wheels 705 lower and contact the ground. Then, the base 1 is lifted up a certain distance. At this time, the moving wheels 705 assist the staff in moving the grate cooler body 2 to the designated position. Then, without the need to prepare special moving tools, the staff can easily move the grate cooler body 2. After arriving at the designated location, simply activate the electric push rod 701 to extend and lower the lifting seat 702, which will allow the moving wheels 705 to move up and make the base 1 fit with the ground, thereby fixing the grate cooler body 2. Finally, it plays a role in facilitating movement when the grate cooler is in use.

[0032] In summary, when using this energy-saving and environmentally friendly grate cooler that can switch between cold air cooling and natural air cooling, the high-temperature clinker is first introduced into the grate cooler body 2 through the feed hopper 3 until it falls onto the grate cooling plate 4. Then, the grate cooler body 2 is started to generate cold air that blows onto the high-temperature clinker, thereby cooling it. Afterward, the cooled clinker is discharged from the grate cooler body 2 through the discharge hopper 5 to enter the next process. This is existing technology and will not be elaborated on here. The auxiliary mechanism 6 enables the switching between cold air cooling and natural air cooling, thereby reducing energy consumption without affecting cooling efficiency and quality. The filter screen 614 filters the dust carried by the gas, preventing the clinker dust carried by the cold air from being directly emitted and causing environmental pollution when passing through the clinker layer. The guide mechanism 7 causes the moving wheels 705 to move down and lift the base 1 up, so that no special moving tools are needed, making it convenient for workers to move the grate cooler body 2. The contents not described in detail in this description are existing technologies known to those skilled in the art.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
