Description

Technical Field

[0001] This utility model relates to the technical field of granular limestone feeding devices, and in particular to an anti-clogging feeding device for limestone. Background Technology

[0002] In the non-ferrous smelting industry, limestone particles are commonly used as raw materials for waste acid treatment. After being added to the silo, the limestone particles are conveyed to the ball mill by a conveying device to make limestone emulsion. This emulsion is then added to the acidic wastewater to make gypsum, thereby removing sulfuric acid from the wastewater. After further treatment, the wastewater can be discharged in compliance with standards or reused.

[0003] However, limestone particles have poor fluidity, so when adding limestone particles, the discharge port often gets blocked. The manual cleaning is labor-intensive, causing long shutdowns and affecting normal production. If the material shortage is not detected in time, it will also affect the quality of wastewater, causing excessive impurities in the drainage and resulting in environmental accidents.

[0019] This application provides an anti-clogging feeding device for limestone, effectively solving the problem of poor flowability of limestone particles, which often leads to clogging of the feeding port when adding limestone particles. This results in heavy manual cleaning, causing prolonged shutdowns and disrupting normal production. Furthermore, failure to detect material shortages in a timely manner can affect wastewater quality, causing excessive impurities in the drainage and potentially leading to environmental incidents. This utility model provides an anti-clogging feeding device for granular limestone that can promptly detect and resolve material shortages caused by clogging of the feeding port, ensuring stable production operation. The device described in this utility model is fully automated, has low cost, and is worthy of widespread application. Example

[0020] like Figure 1 and Figure 2 As shown, the technical solution in this application embodiment effectively solves the problem that limestone particles have poor flowability, which often leads to blockage of the discharge port when adding limestone particles. This results in a large amount of manual cleaning, causing prolonged shutdowns and affecting normal production. Furthermore, if material shortages are not detected in time, it can also affect wastewater quality, causing excessive impurities in the drainage and potentially leading to environmental accidents. The overall concept is as follows: A limestone anti-blockage discharge device includes a hopper 1, a vibrator 2, a conveying device 3, and a control unit 4. The hopper 1 serves as both a storage device and a discharge device for limestone particles. The hopper 1 includes a front guard plate 1. 1. Side guard plate 12, cone 13, grid 14 and discharge port 15. Front guard plate 11 is connected to the front of cone 13, side guard plate 12 is connected to the side of cone 13, discharge port 15 is located at the bottom of cone 13, with a diameter of 200~300mm. Discharge port 15 is installed below hopper 1 to control the discharge of granular limestone. Vibrator 2 is installed below hopper 1 to assist in discharge and to restore the material flow when there is a blockage. Conveying device 3 is installed below discharge port 15 to transport limestone particles to ball mill. Control unit 4 is used to control the fully automatic operation of the anti-blockage discharge device for granular limestone.

[0021] The front guard plate 11 is 2-4m high and made of steel. The side guard plate 12 is the same height as the front guard plate 11 and is made of steel. The side angle of the cone 13 is 20°~45° with the vertical direction.

[0022] The grid 14 is fixedly installed on the top edge of the cone 13 by welding. It is made of steel and is used to block large pieces of limestone from entering the cone 13. The grid 14 is made of steel pipe with a diameter of 50mm and a spacing of 100mm~150mm.

[0023] The vibrator 2 includes a pad 21, a bracket 22, an air hammer 23, a pad 24, an electromagnetic vibrator 25, and a turbulence bar 26. The pad 21 is installed between the bracket 22 and the cone 13 to protect the cone 13 and increase the transmission area of ​​the striking force. One end of the bracket 22 is connected to the pad 21, and the other end is connected to the air hammer 23 to support the air hammer 23 and strike the cone 13.

[0024] The pad 24 is installed between the electromagnetic vibrator 25 and the cone 13 to protect the cone 13 and increase the transmission area of ​​the electromagnetic oscillation. The turbulence rod 26 is a spiral steel rod installed inside the cone 13. One end is connected to the electromagnetic vibrator 25 and is driven by the electromagnetic vibrator 25 to generate high-frequency vibration, which is used to transmit the electromagnetic oscillation to the internal limestone particles and destroy the bridging phenomenon of the limestone particles.

[0025] The materials of pad 21, bracket 22, air hammer 23, pad 24 and baffle 26 are all steel.

[0026] The conveyor device 3 includes a belt 31 and a material breakage detector 32. The material breakage detector 32 is installed above the belt 31 and is used to detect whether the material has broken.

[0027] The control unit 4 is a PLC or DCS system used to control the automatic operation of the material breakage detector 32, the air hammer 23 and the electromagnetic vibrator 25.

[0028] To address the problems existing in the prior art, this utility model provides an anti-blocking feeding device for limestone, specifically for granular limestone. This device can promptly detect material interruption and resolve material interruption problems caused by blockage at the feeding port, ensuring stable production operation. The device mentioned in this utility model can achieve full automation, has low cost, and is worthy of widespread application.

[0029] Working principle:

[0030] The first step is that when the anti-blocking feeding device for granular limestone is running automatically, when the control unit 4 controls the material interruption detector 32 to detect that the belt 31 has been without material for more than 10 seconds, the electromagnetic vibrator 25 will be automatically started to vibrate until the material supply is restored and the electromagnetic vibrator 25 stops running.

[0031] The second step is that after the electromagnetic vibrator 25 has been running continuously for one minute and the material supply has not been restored, the control unit 4 controls the air hammer 23 to run until the material supply is restored and the electromagnetic vibrator 25 and the air hammer 23 stop running.

[0032] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
