BRIEF DESCRIPTION OF THE DRAWINGS
[0015] Figure 1 This is a functional block diagram of an embodiment of the utility model. DETAILED DESCRIPTION
[0016] The following is further described in detail through specific implementation methods:
[0017] The embodiment is basically as shown in the attached Figure 1 As shown: a fly ash disposal system, including a feeding device, a stirring device, a pouring device and a control device, the control device includes a controller, and the feeding device, the stirring device and the pouring device are electrically connected to the controller;
[0018] Among them, the feeding device is used to hold the prefabricated materials composed of fly ash and admixtures. In this embodiment, fly ash is a resource product after waste incineration, and the admixtures include finished sand, cement and water. Therefore, the feeding device includes a fly ash feeding bin and an admixture feeding bin. In order to achieve the purpose of automatic feeding, weighing and feeding, the feeding device also includes a weighing unit and a feeding unit. Specifically, the fly ash feeding bin and the admixture feeding bin control the feeding ratio through their own programs, for example, the fly ash: admixture is 2:1; the weighing unit is located between the feeding bin and the feeding unit, and is used to weigh the weight of the prefabricated materials added to the fly ash feeding bin and the admixture feeding bin. The weighing unit in this application can be composed of existing weighing sensors. After the weighing unit detects that the weight meets the standard, the controller receives the weighing unit signal and controls the feeding unit to open, so that the weighed prefabricated materials are fed to the next step equipment, i.e., the stirring device;
[0019] In the feeding process of the present application, the automatic control effect is achieved through the delay module and the timing module in the control device. Specifically, the delay module and the timing module are electrically connected to the controller. The delay module performs delay processing after the weighing unit completes the weighing. During the delay processing, the controller controls the fly ash feeding bin and the admixture feeding bin to close to wait for the next start of feeding. The waiting time is timed by the timing module. During the timing processing, the controller controls the feeding unit to feed. After the timing processing is completed, the controller controls the fly ash feeding bin and the admixture feeding bin to start, so that the feeding bin continues to feed, thereby realizing the automatic feeding process.
[0020] The stirring device receives the prefabricated materials fed by the feeding unit. The stirring device is a mixer. Specifically, the feeding port of the mixer is connected with the feeding port of the feeding unit, so that the generation of smoke and dust is reduced during the feeding process. The discharge port of the mixer corresponds to the pouring device. The prefabricated materials mixed in the mixer become mixed materials and are fed into the pouring device for pouring.
[0021] The casting device includes a casting mold, a conveying unit, a vibration platform and a spray unit, wherein the casting mold is located on the conveying unit so that the casting mold moves with the conveying unit. The conveying unit is controlled by a controller so that it follows the frequency of the mixer discharging materials to ensure that the casting mold can always receive the mixed material. The conveying end point of the conveying unit is the vibration platform. The casting mold located on the conveying unit can be placed on the vibration platform by means of a mechanical arm, a mechanical claw, etc. The vibration platform is used to perform a vibrating operation on the casting mold containing the mixed material. During the vibrating operation, water sprinkling and maintenance are performed through the spray unit. In this way, the prefabricated blocks of fly ash resource products are generated, waiting for subsequent firing and other treatments.
[0022] In the fly ash disposal process of the present application, it is inevitable that some smoke and dust will be generated. In this regard, the control device also includes a smoke detection module and a water mist spray module. The smoke detection module and the water mist spray module are electrically connected to the controller, and the smoke detection module and the water mist spray module are located above the feeding device, the stirring device and the pouring device. Specifically, the smoke detection module is used to detect the smoke content and transmit the detection signal to the controller. The controller controls the opening and closing of the water mist spray device according to the detection signal, so that when the smoke content exceeds the range, dust is reduced by water mist, thereby reducing smoke pollutants in the fly ash disposal process, protecting the health of operators and reducing the impact on the surrounding environment.
[0023] In this embodiment, the feeding device, the stirring device and the pouring device are all composed of a combination of existing production equipment, the controller adopts a single-chip microcomputer, specifically an STM32 single-chip microcomputer, the timing module and the delay module are timers built into the controller, the smoke detection module is a smoke detection sensor, and the water mist spray module is a water mist nozzle.
