Description

Technical Field

[0001] This utility model relates to the field of chemical feeding technology, specifically a chemical safety feeding device. Background Technology

[0002] In chemical production, many raw materials, intermediates, and products are flammable and explosive. Fires or explosions can cause serious casualties, property damage, and environmental pollution. Therefore, fire and explosion prevention in chemical production is a crucial aspect, impacting the survival and development of enterprises and the stability and safety of society. Automatic weighing and feeding devices play a key role in chemical production. Their working principle is based on high-precision weighing sensors, which can accurately measure the weight of the input materials in real time. When materials enter the device, the sensor converts the weight signal into an electrical signal, which is transmitted to the control system. This device offers significant advantages: precise weighing ensures highly accurate feeding, preventing overfeeding or underfeeding from affecting product quality; it also automates operation, reducing errors and labor intensity associated with manual feeding, improving production efficiency; and it operates in a closed environment, effectively preventing material leakage, reducing health hazards to operators, and ensuring a safe production environment. However, it is necessary to prevent clumping during use.

[0003] The existing mechanism mainly prevents material agglomeration through a combination of mechanical stirring and crushing. The device is equipped with a specially designed stirring paddle, the shape and angle of which are carefully considered. When the material enters the device, it can fully stir the material at a specific speed. This not only keeps the material in a loose state, but also breaks up any small lumps that have formed. At the same time, the device is also equipped with crushing teeth. When the stirring paddle brings the material to a specific position, the crushing teeth will forcibly crush larger lumps. Through mechanical force, the agglomerated material is broken into suitable particles, ensuring that the material always exists in a dispersed state and avoiding the impact of agglomeration on the subsequent feeding process. However, this anti-agglomeration mechanism will wear down after long-term use, thus affecting the effectiveness of the device. Utility Model Content

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. In this utility model, when there is internal clumping and blockage, motor two is started first, which drives large gear one to rotate, and at the same time drives large gear two to rotate. Large gear two drives rotating rod one to rotate, which in turn drives rotating rod two and rotating rod three to rotate. Then, rotating rod three drives fixed block one to push up and down. Then, fixed block one drives connecting rod one to vibrate up and down. At this time, the vibrating plate pushes the box to vibrate up and down, breaking up the clumping.

Then, pinion one passes through the circular hole and drives the forward conveying rod to rotate in the forward direction. At the same time, pinion two passes through the circular hole and drives the reverse conveying pipe to rotate in the reverse direction, thereby achieving the effect of reducing raw material agglomeration and blockage.

[0038] Working principle: When internal lumps and blockages occur, motor 4 is started first. Motor 4 drives large gear 5 to rotate, which in turn drives large gear 6 to rotate. Large gear 6 drives rotating rod 7 to rotate, which in turn drives rotating rod 8 to rotate. Rotating rod 8 drives rotating rod 9 to rotate, which in turn drives fixed block 10 to move up and down. Fixed block 10 then drives connecting rod 11 to vibrate up and down, which in turn drives connecting rod 12 to vibrate. This causes vibrating plate 13 to vibrate, which in turn pushes the box 1 to vibrate up and down, breaking up the lumps. This achieves the effect of dispersing the lumps of raw materials in the box 1 through vibration, preventing blockages.

[0039] When motor 1 201 is started, it drives pinion 1 202 to rotate. Pinion 1 202 then drives pinion 2 203 to rotate. Pinion 1 202 passes through the circular hole 205 and drives the forward conveying rod 206 to rotate in the forward direction. At the same time, pinion 2 203 passes through the circular hole 205 and drives the reverse conveying pipe 207 to rotate in the reverse direction. The forward conveying rod 206 and the reverse conveying pipe 207 work together to convey the raw material, thus reducing the agglomeration and blockage of the raw material.
