DETAILED DESCRIPTION
[0020] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] In the description of the present invention, it should be noted that the terms "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", "front", "back", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.
[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0023] like Figure 1 to Figure 3 As shown, the dry quenching dust ash transfer system described in this embodiment includes an intermediate bin 1, a scraper conveyor 2, a bucket elevator 3, a crusher 4 and an ash bin 5. The intermediate bin 1 is connected to the bucket elevator 3 through a first discharge chute 6, and the bucket elevator 3 is connected to the ash bin 5 through a second discharge chute 7. The crusher 4 is arranged in the second discharge chute 7, and is used for crushing the dust in the second discharge chute 7 and then sending it into the ash bin 5 for transfer.
[0024] This embodiment has a simple structure and a reasonable design. By setting a crusher 4, the coke powder is crushed into small particles before being transported, thereby avoiding damage to the ash conveying pipe wall to pollute the environment and large particles of coke powder clogging the equipment to cause equipment shutdown, thereby increasing the service life of the equipment.
[0025] On the basis of the above embodiment, an electric ash discharge valve 11 is provided at the bottom end of the intermediate bin 1 .
[0026] Specifically, the second discharge chute 7 is provided with an anti-blocking material level meter 71 near the top of the crusher 4 , and the anti-blocking material level meter 71 is interlocked with the electric format ash discharge valve 11 , the scraper conveyor 2 , the bucket elevator 3 and the crusher 4 .
[0027] In the present embodiment, an electric ash discharge valve 11 is provided to facilitate flexible control of the coke powder discharge speed in the intermediate bin 1. By providing an anti-blocking material level meter 71, it is possible to monitor in real time whether the coke powder conveying speed exceeds the working capacity of the crusher 4. If material accumulation occurs, the coke powder conveying in the front section is stopped based on interlocking control. After cleaning and unblocking, each component is opened for transportation.
[0028] Specifically, in this embodiment, a crusher 4 is provided to crush 8 to 10 cm of coke powder into a safe ash conveying range of about 1 mm. When the equipment is running, the crusher 4 is started first, and after normal operation, a command is issued to start the electric format ash discharge valve 11, the scraper conveyor 2 and the bucket elevator 3. When the anti-blocking material level meter 71 detects the occurrence of a blockage, the crusher 4 and the electric format ash discharge valve 11, the scraper conveyor 2 and the bucket elevator 3 and other components are immediately stopped. When the system stops, the system is shut down in sequence from front to back. The crusher 4 continues to run for 2-5 minutes after the front-end ash discharge and transfer system stops, and then stops.
[0029] In some embodiments, the first material discharge chute 6 is set at an inclined angle, and the inclined angle is set to 40-60°; the second material discharge chute 7 is set at an inclined angle, and the inclined angle is set to 30-45°.
[0030] The present embodiment specifically shows the inclination angle settings of the first material discharge chute 6 and the second material discharge chute 7 so as to achieve a better material discharge effect. The structure is simple and the material discharge is smooth.
[0031] In some embodiments, the crusher 4 is provided with a crushing box 41, a crushing roller group 42, a driving structure 43 and a screen structure 44; the crushing box 41 is installed on the second discharge chute 7; the crushing roller group 42 is rotatably installed on the crushing box 41; and the crushing roller group 42 is provided with a crushing tooth structure for crushing dust particles; the driving structure 43 is arranged on one side of the crushing box 41 and is drivingly connected to the crushing roller group 42; the screen structure 44 is arranged at the bottom end of the crushing box 41 for screening the discharge material.
[0032] Specifically, a pressure-resistant layer 421 is connected to the surface of the crushing roller set 42 , and a plurality of pressure-resistant blocks 422 for mounting the crushing tooth structure are arranged on the pressure-resistant layer 421 .
[0033] More specifically, a feed opening 411 is provided at the top of the pulverizing box 41 , and the feed opening 411 is designed to be open.
[0034] In this embodiment, the crusher 4 is specifically shown, which crushes the coke powder by setting a crushing roller set 42, and the crushing roller set 42 is driven by a driving structure 43, which can be specifically driven by a driving motor, and a pressure-resistant layer 421 is installed on the surface of the crushing roller set 42, and a pressure-resistant block 422 is installed on the pressure-resistant layer 421 to install a crushing tooth structure. When crushing, the coke powder enters the inside of the crushing roller set 42, and the surface of the coke powder is squeezed by the crushing tooth structure, and the coke powder is broken by using the principle that the smaller the contact surface, the greater the pressure it bears. When crushing, the impact force generated by the crushing is buffered by the pressure-resistant block 422 and the pressure-resistant layer 421, so as to ensure the crushing effect and delay the loss of the crushing roller set 42, so as to effectively improve its service life.
[0035] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they 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 variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
