Description

Technical Field

[0001] The invention relates to the technical field of automatic starting of a foam pump when power is cut off, and in particular to a device for automatically starting a foam pump when power is cut off. Background Art

[0002] The foam pump is well adapted to the foam that occurs in flotation and other mineral processing industries due to its special structural design, so it is called a foam pump. In fact, it is also a type of centrifugal slurry pump. The pump head is a double pump shell structure, and the flow-through parts are made of hard nickel, high chromium or rubber materials. Its transmission part is common to the EVM (R) type slurry pump.

[0003] The existing foam pump automatically starts after a power outage, and usually needs to be equipped with some automatic recovery control systems to ensure that the pump can automatically restart after a power outage; common ways to achieve this function include using a power-off automatic recovery controller or a related electrical control system. During use, the electrical control system is usually installed in a chassis, and in order to ensure heat dissipation, a corresponding heat dissipation component is usually installed on the chassis. However, during the heat dissipation process, external dust can easily enter the chassis from the heat dissipation component, resulting in a lot of dust in the chassis, posing a safety hazard, and the heat generated during use will accumulate on the top of the chassis, causing the temperature in the chassis to rise, the heat dissipation efficiency is poor, and the service life of the equipment is affected. Therefore, a foam pump power-off automatic starting device is urgently needed to solve the existing problems. Summary of the invention

The soft starter can smooth the startup process and prevent excessive current shock during startup. The voltage monitor can detect voltage fluctuations, abnormalities or power outages, and automatically trigger the startup process after power is restored. The voltage monitor can be used in conjunction with the pump start controller to achieve more precise control. During use, the heat in the chassis is extracted through the cooling fan, and the dustproof net prevents large foreign matter from entering the chassis. At the same time, during the heat dissipation of the chassis, the electrostatic adsorption net in the dust removal component is fixed to the chassis through the connecting seat, and is connected to the power supply line through the line interface on the top connecting seat. At this time, the electrostatic adsorption net is energized to generate static electricity. The generated static electricity can effectively adsorb dust entering from the heat dissipation component, avoid a large amount of dust entering the chassis, and prevent safety hazards.
