Problems solved by technology

The so-called sequential type is equivalent to a mechanical device. After the air source is input, it always acts mechanically. For the cleaning time of a single pulse valve, the interval time between valves, the cleaning interval time, and the start and stop time of the ash conveying device Such parameters cannot be adjusted arbitrarily; the designed air bag structure and gas storage capacity cannot guarantee the dust removal requirements, so the dust removal effect is not good.
The dust attached to the filter cartridge cannot be removed for a long time, and it is easy to agglomerate on the filter cartridge to block the filter holes, increase the resistance, and finally lead to a significant decrease in the suction volume, and even the paralysis of the dust removal system

Embodiment 1

[0026] as Figure 1- Figure 3 As shown, a fully automatic mining dry dust collector based on PLC control, comprising the body part and the control part, the body part comprises a shell, a blowing ash cleaning device, a scraper ash conveying device 103, a filter cartridge 107, a compressed air system, the housing is composed of two boxes 101 in series, each box 101 is separated into upper and lower parts by a flower plate, the flower plate is branched and column fixed multiple filter cartridges 107, and the upper part of the filter cartridge 107 is arranged spraying ash cleaning device, The scraper ash conveying device 103 is arranged at the bottom of the box 101, the shell portion of the scraper ash conveying device 103 is indented inward from both sides of the box 101, and the housing of the dust collector is integrated into a structure, so that the height of the box 101 is reduced; the scraper ash conveying device 103 adopts an aerodynamic motor 111 transmission drive; the compre...

Embodiment 2

[0031] as Figure 4 、 Figure 5 、 Figure 6 Shown, is another way of structure of the present invention. The difference between Example II and the embodiment is that the direction of the access door 102 is arranged on the side panel of the box 101, and the air inlet is arranged in the horizontal direction. In addition, other structures are associated with Figure 1 、 Figure 2 、 Figure 3 Same.

[0032]The working principle of the present invention is: PLC control box 110 after the input power supply, in standby. When the main control signal input, such as the fan and other upper associated equipment start and stop signal, or when the differential pressure transmitter 5 input pressure exceeding the limit signal, the PLC control box 110 began to work, in turn to start the first pneumatic solenoid valve 109 or the second pneumatic solenoid valve 106. When opening the second pneumatic solenoid valve 106, the pneumatic pulse valve 112 will be connected to the pneumatic pulse valve 112 throu...

Abstract

The invention discloses a full-automatic mining dry dust collector based on PLC control, the full-automatic mining dry dust collector comprises a body part and a control part, the body part comprises a shell, a scraper ash conveying device, filter cartridges and a compressed air system, the shell is formed by connecting a front box body and a rear box body in series, each box body is internally divided into an upper part and a lower part through a pattern plate, a plurality of filter cartridges are fixed on the pattern plate, and the control part is connected with the control part. The blowing ash removal device is arranged above the filter cartridge, the scraper ash conveying device is arranged at the bottom of the box body, and the scraper ash conveying device is driven by a pneumatic motor in a transmission manner; the compressed air system is connected with the blowing ash removal device and the scraper ash conveying device, and the control part comprises a PLC control box, a pneumatic electromagnetic valve and a pneumatic pulse valve and controls the blowing ash removal device and the scraper ash conveying device in real time. The pneumatic electromagnetic valve playing a control role and the pneumatic pulse valve playing an execution role are separated, the safety standard requirement of the mine dry dust collector is met, the failure rate is reduced, maintenance is convenient, and the operation reliability is improved.

Description

Technical field [0001] The present invention relates to the field of dust collectors, particularly to a fully automatic mine dry dust collector based on PLC control. Background [0002] Dry dust collector is to filter cartridges, filter bags and other filter materials to achieve dust and gas separation equipment, in the ground of the industrial and mining enterprises of various dust points, dry dust collector application is very common. After the filter element on the dry dust collector is used for a period of time, the dust will be stained on the surface, so that the filtration resistance increases, usually using compressed air for reverse blowback cleaning, to achieve the regeneration of filtration performance, the use of screw machine or scraper machine to achieve the recovery of dust transportation. To achieve the function of ash cleaning, it is generally the use of PLC control device and electromagnetic pulse valve to carry out automation work. The so-called electromagnetic ...
