Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of TGS lime kilns, and particularly relates to an automatic uniform ash discharging device for a TGS lime kiln. Background Art
[0002] The TGS lime kiln is a common lime production process. Its basic process is to transport limestone from the raw material bin to the kiln through a feeding device. After high-temperature calcination, the finished quicklime is obtained, and then the quicklime is transported to the lime bin for storage through an ash discharging device. The ash discharging device of the TGS lime kiln mainly includes equipment such as an ash discharging support plate, a hopper, a discharging valve, and a kiln bottom belt conveyor. At present, most of the ash discharging devices of lime kilns adopt mechanized and automated equipment, which saves manpower, but has the following defects:
[0003] 1. The traditional ash discharging support plate consists of two pairs (4 pieces). It has a large area and cannot achieve precise control of the ash discharging amount in a small range, easily resulting in uneven ash discharging. As the capacity of the kiln type increases, the problem of uneven ash discharging becomes more serious, easily causing overburning in one part and underburning in another part.
[0004] 2. The receiving port of the kiln bottom belt conveyor is prone to material jamming. If not discovered in time, it is easy to cause damage to the belt. Summary of the Invention
[0005] The purpose of the utility model is to provide an automatic uniform ash discharging device for a TGS lime kiln to solve the problems existing in the prior art.
[0006] The technical solution adopted by the utility model to solve its technical problems is as follows:
[0007] An automatic uniform ash discharging device for a TGS lime kiln includes a kiln body. Four ash discharging support plates are installed at the bottom of the kiln body. Sixteen auxiliary support plates are installed on the kiln body above the ash discharging support plates. A weighing hopper is installed below the discharging end of the kiln body. A discharging valve is installed at the discharging port of the weighing hopper, and a belt conveyor is installed below the discharging valve.
[0008] Further, the ash discharging support plates, auxiliary support plates, weighing hopper, discharging valve, and belt conveyor are electrically connected to a PLC control system.
[0009] Further, the auxiliary support plates are fan-shaped. The radius of the auxiliary support plates is the same as that of the ash discharging support plates. The arc length of the auxiliary support plates is 1 / 4 of that of the ash discharging support plates. The driving mode of the auxiliary support plates is the same as that of the ash discharging support plates. The sixteen auxiliary support plates are circularly arrayed in the kiln body, and every four auxiliary support plates correspond to one ash discharging support plate.
[0010] Further, the weighing hopper is a hopper with a weighing sensor. The weighing hopper is electrically connected to the PLC control system through the weighing sensor.
[0011] Further, the PLC control system is equipped with an alarm.
[0012] The utility model has the following beneficial effects:
[0013] On the basis of the original ash discharge supporting plate, the utility model newly adds 16 auxiliary supporting plates, which can evenly control the discharge of the kiln body, prevent uneven discharge, and collect the discharge weight in real time through the weighing hopper. When the weight change value within a predetermined period fails to reach the set value, the PLC control system gives a material jamming alarm through the alarm, and the personnel can intervene and process in time after receiving the information to prevent the expansion of the material jamming fault.

[0018] In order to make the purpose, technical solutions and advantages of the utility model clearer, the following further describes the utility model in detail with reference to specific embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.
[0019] As Figures 1-3 shown, an automatic uniform ash discharge device for a TGS lime kiln includes a kiln body 1, 4 ash discharge supporting plates 2 are installed at the bottom of the kiln body 1, 16 auxiliary supporting plates 3 are installed on the kiln body 1 above the ash discharge supporting plates 2, a weighing hopper 4 is installed below the discharge end of the kiln body 1, a discharge valve 5 is installed at the discharge port of the weighing hopper 4, and a belt conveyor 6 is installed below the discharge valve 5.
[0020] The ash discharge supporting plate 2, the auxiliary supporting plate 3, the weighing hopper 4, the discharge valve 5, and the belt conveyor 6 are electrically connected to the PLC control system.
[0021] The auxiliary pallet 3 is fan-shaped. The radius of the auxiliary pallet 3 is the same as that of the ash discharging pallet 2. The arc length of the auxiliary pallet 3 is 1 / 4 of that of the ash discharging pallet 2. The driving mode of the auxiliary pallet 3 is the same as that of the ash discharging pallet 2. Sixteen auxiliary pallets 3 are circularly arrayed in the kiln body 1, and every four auxiliary pallets 3 correspond to one ash discharging pallet 2. The ash discharging pallet 2 is the original discharging device of the kiln body 1, and its driving mode is cylinder driving. The ash discharging pallet 2 slides back and forth inside the kiln body 1 under the driving of the cylinder, so as to form an ash discharging gap for ash discharging. It is expected that the driving mode of the auxiliary pallet 3 is the same. First, according to the lime sampling conditions of each part, the lime is evenly distributed through the auxiliary pallet 3, and then discharged through the ash discharging pallet 2, so as to achieve the purpose of uniform ash discharging.
[0022] The weighing hopper 4 is a hopper with a weighing sensor. The weighing hopper 4 is electrically connected to the PLC control system through the weighing sensor.
[0023] The PLC control system is equipped with an alarm.
[0024] The working principle of the present utility model is as follows:
[0025] The finished lime calcined in the kiln body 1 is transported to the finished product storage bin through the auxiliary pallet 3, the ash discharging pallet 2, the weighing hopper 4, the discharging valve 5, and the belt conveyor 6. Sixteen auxiliary pallets 3 are evenly arranged around the kiln body 1. Each auxiliary pallet 3 can be individually controlled through the PLC control system. According to the lime sampling conditions of each part, the action times of the auxiliary pallet 3 at the corresponding position are set to control the ash discharging amount at this part. The ash discharging process automatically executes the predetermined instructions by the PLC system. Personnel only need to slightly adjust the action times of each auxiliary pallet 3, that is, to realize the adjustment of the ash discharging amount of each part, so as to ensure the uniformity of lime calcination in each part.
[0026] The finished lime is weighed in the weighing hopper 4. After the belt conveyor 6 runs and the discharging valve 5 is opened, the weight of the hopper is collected in real time, and the change of the weight is compared and analyzed. When the change value of the weight within the predetermined period fails to reach the set value, the PLC control system gives a material jamming alarm through the alarm, and personnel receive the information and intervene in time to prevent the expansion of the material jamming fault.
[0027] The embodiments described above are only used to describe the preferred embodiments of the present utility model, and do not limit the concept and scope of the present utility model. Without departing from the design concept of the present utility model, various modifications and improvements made by those of ordinary skill in the art to the technical solutions of the present utility model should fall within the protection scope of the present utility model.
