Dry-type trolley differential pressure detection alarm device, method and system

Abstract

The invention provides a dry-type trolley differential pressure detection alarm device which comprises a dry-type trolley body and self-locking universal wheels, the self-locking universal wheels are fixed to the bottom of the dry-type trolley body at equal intervals, a mounting base plate is fixed to one side of the dry-type trolley body, a transmitter is connected to one side of the mounting base plate in a clamped mode, three mounting lug blocks are fixed to the side, close to the mounting base plate, of the transmitter at equal intervals, a differential pressure sensor is fixed to the side, close to the mounting base plate, of the dry-type trolley body, and the detection end of the differential pressure sensor extends into the dry-type trolley body. The device can automatically detect the pressure at the two sides of filter cotton in the main body of a dry-type trolley, can automatically give an alarm when the pressure difference at the two sides is different due to the fact that much waste paint is accumulated on the filter cotton, and meanwhile can facilitate people to disassemble and assemble the transmitter in the daily maintenance process; and various transmitters with different sizes can be conveniently replaced and mounted.

Description

technical field [0001] The invention relates to the technical field of differential pressure detection of dry trolleys, in particular to a differential pressure detection and alarm device, method and system for dry trolleys. Background technique [0002] The dry spray booth is composed of a dynamic and static pressure chamber, a spraying operation room, a paint mist separation room, and an exhaust system. The paint mist separation room is equipped with a paint mist separation device. The dry spray booth is relative to the wet spray booth. The type spray booth is a type of spray booth. It is named after the paint mist separation device does not use water in the process of separating the paint mist and uses a dry method to separate the paint mist. The dry paint mist separation device separates the paint There are many principles of fog, some use the principle of filtration to separate paint mist, some use the principle of electrostatic separation to separate paint mist, and so...

AI Technical Summary

Problems solved by technology

[0003] Existing dry spray booths usually use a detachable dry waste paint collection trolley at the bottom to collect waste paint, and filter cotton is usually installed in this dry waste paint collection trolley. Carry out the work of filtering and collecting waste paint, and this kind of filter cotton usually has a certain thickness of waste paint accumulated on the surface, and it needs to be cleaned by dismantling the dry waste paint collection trolley, and if it is not cleaned in time, it will be very serious. Affect the treatment and collection effect of waste paint, and the traditional dry waste paint collection trolley usually checks the waste paint accumulated on the filter cotton through manual inspection, and if manual inspection requires manual disassembly of the dry waste paint collection trolley, Manually observe the waste paint on the filter, the whole operation process is very cumbersome and complicated, and the accuracy of manual observation is very low
