AI Technical Summary
Traditional electrostatic release devices cannot intuitively monitor the contact situation when workers contact their hands, and the contact time is short, so they cannot effectively release static electricity, and lack reminder function.
An electrostatic elimination device is designed, including a spherical handball, connecting rod, slider, accommodating groove, pin rod, semispherical contact ball, threaded hole, bolt and metal soft rope. Through the cooperation of these components, workers can transmit static electricity through the handball and transfer it to the ground through the metal component. The device also reminds the static release through the spring blade and the connecting rod.
It realizes the effective transmission and release of static electricity in the worker's hands, ensuring that static electricity is completely removed before entering the fertilizer workshop, and avoiding sparks and dangers caused by static electricity.

[0002] Fertilizer, chemical fertilizer, refers to the waste of one or several nutrients needed for the growth of crops made by chemical and physical methods, also known as inorganic fertilizer, including nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer, micro-fertilizer and compound fertilizer, etc. Fertilizer has the following characteristics: simple ingredients, high nutrient content, fast fertilizer effect, strong fertilizer effect, some fertilizers contain acid-base reactions, generally do not contain organic matter, and have no function of improving soil and fertilizing. In the process of producing some waste materials containing combustible raw materials such as ammonium nitrate and potassium nitrate, special attention should be paid to the hazards of static electricity. Especially in the production process, the operation of various mechanical equipment and the flow of personnel can easily cause static electricity release. Static electricity release will release high voltage electricity in a short time, accompanied by sparks. When producing some fertilizers with special properties, special attention should be paid to static electricity.
[0003] For workers entering and leaving the fertilizer production workshop, static electricity needs to be released from them. Traditional static electricity release devices only allow workers to touch the static electricity release device with their hands. During the static electricity release process, it is not possible to intuitively see whether the worker's hands are in contact with the static electricity release device. Secondly, during the static electricity release process, the contact time between the worker and the static electricity release device is short, and static electricity cannot be released well. Finally, there is no reminder device during the static electricity release process. Therefore, in view of the above problems, an static electricity elimination device for chemical safety is proposed.
