[0020] In the description of the utility model, it needs to be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise" are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and cannot be understood as indicating or implying that the indicated device or element must have a particular orientation, a particular orientation and operation, so it cannot be understood as a limitation on the utility model.

[0021] In addition, the terms "first", "second" are only used for descriptive purposes and cannot be understood to indicate or imply relative importance or imply the number of indicated technical features. Therefore, the features defined as "first", "second" can explicitly or implicitly include one or more of the features. In the description of the utility model, the meaning of "multiple" is two or more than two, unless otherwise explicitly specified and limited.

[0022] In the utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "connection", "fixing" and the like should be broadly understood, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, it can be the communication inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0023] Figure 1 It is the schematic diagram of the traditional pressure difference table for measuring the pressure difference of the dust collector body, since the inlet pipe and the outlet pipe of the dust collector body are spaced too long, the pressure guide pipe connected with the pressure difference table is too long, it is inconvenient to clean, it is easy to cause the pressure guide pipe to be blocked, so that the pressure difference measurement of the dust collector is inaccurate.

[0024] Please refer to Figure 2 To solve the above problems, the utility model provides a kind of device for measuring the pressure difference of dust collector body, comprising:

[0025] Dust collector body 2, one end of the dust collector body 2 is communicated with the inlet pipe 1, the other end of the dust collector body 2 is communicated with the outlet pipe 3;

[0026] Inlet negative pressure gauge 7 is arranged on the inlet pipe 1, and is used to measure the inlet pressure value of inlet pipe 1;

[0027] Outlet negative pressure gauge 9 is arranged on the outlet pipe 3, and is used to measure the outlet pressure value of outlet pipe 3;

[0028] PLC system 8, the PLC system 8 is connected with the inlet negative pressure gauge 7 and the outlet negative pressure gauge 9 respectively, and is used to judge whether the pressure difference of dust collector body 2 is normal according to inlet pressure value and outlet pressure value.

[0029] When running normally, there is a certain pressure difference in the dust collector, which is monitored in real time by the differential pressure gauge. For example, when the bag-type dust collector works normally, the differential pressure is usually within a certain range (such as 500-2000Pa), if the reading of the differential pressure gauge exceeds this range, it may indicate that the dust collector has a problem.

[0030] Further, when the difference between the inlet pressure value and the outlet pressure value calculated by the PLC system is between 500-1500 Pa, the pressure difference of the dust collector body 2 is within the normal range. When the difference between the inlet pressure value and the outlet pressure value calculated by the PLC system is above 1500 Pa, the pressure difference of the dust collector body 2 is abnormal, reminding the operator that there may be filter bag blockage, pipeline dust deposition and the like, and issuing a filter bag blockage or pipeline dust deposition alarm. When the difference between the inlet pressure value and the outlet pressure value calculated by the PLC system is below 500 Pa, the pressure difference of the dust collector body 2 is abnormal, and it may be filter bag damage or pipeline leakage and the like, and issuing a filter bag damage or pipeline leakage alarm.
