Description

Technical Field

[0001] The utility model relates to the technical field of grate coolers, in particular to a high-efficiency and energy-saving grate cooler structure. Background Art

[0002] The grate cooler is an important main equipment in the clinker burning system of a cement plant. Its main functions are to cool and convey cement clinker, and at the same time provide hot air for the rotary kiln and decomposition furnace, etc. It is the main equipment for heat recovery in the burning system. The grate cooler is a type of quenching cooler. After the clinker enters the cooler from the kiln, it forms a layer of material with a certain thickness on the grate plate. The blown cold air passes through the moving material layer on the grate bed in a direction perpendicular to each other, so that the clinker can be quenched rapidly. The clinker can be quenched from 1300 - 1400 °C to below 100 °C within several minutes.

[0003] Problems compared with the prior art: Most of the existing grate coolers are of an open structure. When cooling the clinker, they are easily interfered by external airflows and cannot accurately classify and collect hot air at each stage. Secondly, the existing grate coolers have poor flexibility in transporting the clinker. During the transportation process, the clinker is prone to accumulation, so that the clinker cannot be evenly distributed on the movable grate bed, which further leads to the clinker not being able to fully contact with the cold air, reducing the efficiency and quality of the clinker cooling operation, increasing the energy consumption during the use of the grate cooler, and making the practicality of the grate cooler poor. For this reason, we propose a high-efficiency and energy-saving grate cooler structure to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a high-efficiency and energy-saving grate cooler structure.

One side of the installation cover is provided with a feeding mechanism. The top of the frame is provided with a cooling mechanism. The cooling mechanism includes an installation base, which is fixed to the top of the frame by bolts. The top of the installation base is fixed with a slide rail, and a plurality of movable grate beds are slidably connected to the top of the slide rail. One end of each of the plurality of movable grate beds is fixed with an air inlet pipe. A reciprocating driving mechanism is arranged outside the frame.

A collection mechanism is arranged on the outside of the mounting cover, and a crushing mechanism is arranged at the bottom of the frame.

[0029] Please refer to Figures 1-7 , the present utility model provides a technical solution: including a frame 100, a control panel 110 is provided on one side of the frame 100, the edge of the top of the frame 100 is fixed with a mounting cover 120 by bolts, a feeding mechanism is provided on one side of the mounting cover 120, a cooling mechanism is provided on the top of the frame 100, the cooling mechanism includes a mounting base 310, a slide rail 320, a movable grate 330 and an air inlet pipe 331, and a reciprocating driving mechanism is provided outside the frame 100;

[0030] The reciprocating driving mechanism includes a mounting block 410, a hydraulic rod 420 and a driving bracket 430, a collecting mechanism is provided outside the mounting cover 120, and a crushing mechanism is provided at the bottom of the frame 100; a cooling mechanism is provided, and the movable grate 330 is driven to move in an alternating reciprocating manner through the reciprocating driving mechanism, so that the clinker can be transported in an alternating reciprocating manner, ensuring that the transported clinker can be in full contact with the cold air, improving the efficiency and quality of the clinker cooling operation, and further reducing the energy consumption during the use of the grate cooler. The hot air generated at each stage during the cooling operation is collected by the collecting mechanism. Through the relatively closed cooling space formed by the mounting cover 120, the influence of external air flow on the hot air collection operation can be avoided, enabling the collecting mechanism to accurately classify and collect the hot air at each cooling stage, and improving the stability of the cooling operation.

[0031] Specifically, the feeding mechanism includes a mounting side plate 210. One side of the mounting cover 120 is fixed to the mounting side plate 210 by bolts. One side of the mounting side plate 210 is fixed with a feeding pipe 220. One side of the feeding pipe 220 is fixed with a fixed grate plate 230. The bottom of the fixed grate plate 230 is fixed to a support frame 240 by bolts, and the support frame 240 is fixedly connected to the machine frame 100. By providing the feeding mechanism, the clinker enters the interior of the mounting cover 120 through the feeding pipe 220, and the clinker gradually slides downward on the fixed grate plate 230 with an inclined structure. The collecting mechanism located above the fixed grate plate 230 can adsorb and collect the hot gas at the highest temperature, and this part of the hot gas can be used by the decomposition furnace.

[0032] Specifically, a guiding plate 231 is fixed to the top of the fixed grate plate 230. By providing the guiding plate 231 to cooperate with the fixed grate plate 230 for guiding and transporting the clinker, the incoming clinker can be distributed in a trapezoidal shape on the fixed grate plate 230, thereby realizing the uniform distribution of the clinker, avoiding the accumulation of the clinker at the fixed grate plate 230, and ensuring the cooling effect of the grate cooler on the clinker.

[0033] Specifically, a limiting sliding groove 431 is slidably connected to the bottom of the driving support 430, and the limiting sliding groove 431 is fixedly connected to the mounting base 310. By providing the limiting sliding groove 431 to limit and support the movement of the driving support 430, the stability of the driving operation is ensured.

[0034] Specifically, the collection mechanism includes a plurality of suction hoods 510. A plurality of the suction hoods 510 are all fixed to the top of the mounting hood 120 by bolts. A gas delivery pipe 520 is fixed to the top of each of the plurality of suction hoods 510. A suction fan 530 is fixed to one end of the gas delivery pipe 520. The suction fan 530 is fixedly connected to the frame 100 by bolts. By providing multiple sets of collection mechanisms, starting from the collection mechanism at the feeding mechanism part and moving backward in sequence, hot gases at different temperatures of the clinker are collected respectively. The suction fan 530 is started. The suction fan 530 adsorbs the hot air through the gas delivery pipe 520. The collection mechanism located above the fixed grate 230 can adsorb and collect the hot gas at the highest temperature (800 - 950 °C). This part of the hot gas can be used by the decomposition furnace. The next set of collection mechanisms can adsorb and collect the hot gas at the intermediate temperature (300 °C). This part of the hot air can be used for drying air. The next set of collection mechanisms can adsorb and collect the hot gas at a relatively low temperature (150 - 300 °C). This part of the hot air can be directly discharged after filtration. Cooperating with the cold air entering from the bottom of the cooling mechanism, the all-round cooling operation of the clinker is realized. The relatively enclosed cooling space formed by the mounting hood 120 can prevent the external air flow from affecting the hot air collection operation, enabling the collection mechanism to accurately classify and collect the hot air at each cooling stage, and improving the stability of the cooling operation.

[0035] Specifically, the crushing mechanism includes a hopper 610. The hopper 610 is fixed to the inner wall of the frame 100 by bolts. A crusher 620 is fixed to the bottom of the hopper 610.

The crusher 620 performs a crushing operation on the clinker. The crushed clinker is discharged through the discharge chute 630.

[0036] Working principle: When in use, the operation of the grate cooler is controlled through the control panel 110. The clinker enters the interior of the installation cover 120 through the feed pipe 220. The clinker gradually slides downward on the fixed grate plate 230 with an inclined structure. The guide plate 231 cooperates with the fixed grate plate 230 to guide and transport the clinker, and can distribute the incoming clinker in a trapezoidal shape on the fixed grate plate 230, thereby realizing the uniform distribution of the clinker. The clinker is conveyed to the tops of multiple movable grates 330 through the feeding mechanism. Cold air is injected into the interior of the movable grates 330 through the air inlet pipe 331. Then, the cold air is blown upward from the bottom of the clinker through multiple groups of air-permeable mesh plates on the movable grates 330. The driving brackets 430 on the opposite sides are respectively connected to the movable grates 330 arranged in odd and even numbers. The movable grates 330 arranged in odd and even numbers are driven by the hydraulic rods 420 on the opposite sides to move in different directions, thereby realizing the staggered reciprocating movement of the movable grates 330, and can perform staggered reciprocating transportation on the clinker, so that the clinker can be evenly distributed on the movable grates 330, ensuring that the transported clinker can be in full contact with the cold air. Starting from the collection mechanism at the feeding mechanism part and moving backward in sequence, hot gases at different temperatures are collected from the clinker respectively. The suction fan 530 is started, and the suction fan 530 adsorbs the hot air through the air delivery pipe 520 and the suction fan 530. The collection mechanism located above the fixed grate plate 230 can adsorb and collect the hot gas at the highest temperature (800 - 950 °C), and this part of the hot gas can be used for the decomposition furnace. The next group of collection mechanisms can adsorb and collect the hot gas at the intermediate temperature (300 °C), and this part of the hot air can be used for drying air. The next group of collection mechanisms can adsorb and collect the hot gas at a lower temperature (150 - 300 °C), and this part of the hot air can be directly discharged after filtration. Cooperating with the cold air entering from the bottom of the cooling mechanism, the all-round cooling operation of the clinker is realized. Through the relatively enclosed cooling space formed by the installation cover 120, the influence of external air flow on the hot air collection operation can be avoided, so that the collection mechanism can accurately classify and collect the hot air at each cooling stage. The cooled clinker is transported into the hopper 610 through the movable grate 330, and the clinker is crushed through the crusher 620. The crushed clinker is discharged through the discharge chute 630.
