DETAILED DESCRIPTION

[0027] The use method of the utility model is further explained below in combination with the drawings and specific embodiments.

[0028] As Figures 1 to 4 Shown, a kind of coal gasification filter machine deviation rectifying device, comprising:

[0029] Frame 1

[0030] Multiple drive rollers 2 are arranged on the frame 1

[0031] Filter cloth 3 is arranged on the drive roller 2

[0032] Further comprising:

[0033] Deviation rectifying roller 4 is fixedly arranged at one side of the filter cloth 3 at first end, and second end is movably arranged at the other side of the filter cloth 3;Deviation rectifying roller 4 is used to correct the filter cloth 3 that runs deviation.

[0034] Deviation rectifying air cylinder 5 is connected with the second end of the deviation rectifying roller 4, and the deviation rectifying air cylinder 5 is used to push the second end of the deviation rectifying roller 4 to move, so that the filter cloth 3 on the deviation rectifying roller 4 is adjusted to restore to original position;304 stainless steel material is adopted, and service life is long, corrosion resistant.

[0035] Sensor 6 is arranged on the frame 1 and is used to detect the position of the filter cloth 3.

[0036] The device has simple and light structure, is easy to maintain and use, has less cost input, has good filter cloth 3 deviation detection effect, has long service life, has low failure rate, saves manpower and material resources, removes the bottleneck of production operation, and guarantees normal operation of system.

[0037] Both sides of the frame 1 are respectively provided with fixed base 41 and mobile base 43, the fixed base 41 is connected with the deviation rectifying roller 4 through first bearing 42, the mobile base 43 is connected with the deviation rectifying roller 4 through second bearing 44, and the deviation rectifying air cylinder 5 is connected with the mobile base 43 to drive the mobile base 43 to slide on the frame 1 and drive the second end of the deviation rectifying roller 4 to move.

[0038] The output end of the correction cylinder 5 is connected to the second bearing 44. It is made of 304 stainless steel, which is corrosion-resistant and has a long service life.

[0039] The correction cylinder 5 is connected to the instrument 52 via a two-position five-way electric control valve 51, and the sensor 6 is electrically connected to the instrument 52.

[0040] The sensor 6 is a laser sensor 6. Six laser sensors 6 are installed, three on each side of the filter cloth 3, with the three laser sensors 6 installed on the same horizontal plane and spaced a certain distance apart. The laser sensor 6 has strong anti-interference ability, accurate and reliable operation, low cost, relatively simple electrical circuit, and convenient maintenance.

[0041] like Figure 1 As shown, when the filter cloth 3 deviates towards the upper laser sensor 6, it blocks the laser signal from the upper laser sensor 6. The laser sensor 6 outputs a signal, and the controller controls the two-position five-way electric control valve 51 to output compressed air. The piston rod of the correction cylinder 5 extends, and the correction roller 4 deflects at a certain angle as shown in the figure. Under the action of the correction roller 4, the deviation of the filter cloth 3 is quickly corrected, and it moves towards the lower laser sensor 6. When it reaches the middle position, the signal from the upper laser sensor 6 disappears, the correction cylinder 5 resets, and the correction shaft exits the correction state.

[0042] like Figure 2 As shown, when the filter cloth 3 deviates towards the direction of the lower laser sensor 6, it blocks the laser signal from the lower laser sensor 6. The laser sensor 6 outputs a signal, and the controller controls the two-position five-way electric valve 51 to output compressed air. The piston rod of the correction cylinder 5 retracts, and the correction roller 4 deflects at a certain angle as shown in the figure. Under the action of the correction roller 4, the deviation of the filter cloth 3 is quickly corrected, and it moves towards the upper laser sensor 6. When it reaches the middle position, the signal from the lower laser sensor 6 disappears, the correction cylinder 5 resets, and the correction shaft exits the correction state.

[0043] Working process: When the filter cloth 3 starts running through the drive roller 2, if the filter cloth 3 shifts to any side, it will block the laser sensor 6 between the upper and lower parts of the filter cloth 3. The laser sensor 6 will output a signal to the control unit. The control unit controls the two-position five-way solenoid valve 51 to output compressed air, thereby driving the correction cylinder 5 to start and causing the correction roller 4 to shift, thereby correcting the filter cloth 3 and restoring it to its original position. When the sensing signal of the laser sensor 6 disappears, the correction cylinder 5 returns to its original position, thereby causing the correction shaft to exit the correction state, which greatly improves the correction efficiency.

[0044] It should be pointed out finally: the above is only the preferred embodiment of the utility model, and is not used to limit the utility model, although the utility model is described in detail with reference to the embodiment, for the skilled person in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or make equivalent replacement to part of technical features, but any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
