Description

Technical Field

[0001] The utility model relates to the technical field of chemical production equipment, in particular to an automatic deviation-correcting device for a belt filter. Background Art

[0002] The belt type vacuum filter is the main solid-liquid separation equipment in chemical production. The existing filter correction system is an airbag correction system. This correction system has a simple structure, but in actual production and use, the correction effect is poor. The main reason is that the center distance of the bearing seat is constantly changing and extending during the correction process. The original correction bearing design uses a seated spherical bearing. This type of bearing is mainly used in working conditions where the installation positioning is not accurate enough, the axis alignment between the shaft and the seat hole is poor, and the shaft is long and the deflection is large. The main function of the self-alignment is to alleviate the problem of axis alignment and shaft length winding. It is not suitable for places where the self-alignment is frequent. The method to solve the extension of the center distance has defects and the correction device has a short service life. After the correction device is damaged, the filter cloth deviation cannot be adjusted and the correction roller shaft head is abnormally worn; in severe cases, the shaft head is broken, the filter cloth is pulled and the equipment is abnormally shut down. However, replacing the correction device and the correction roller requires more manpower and takes a long time, which has a great impact on the equipment operation rate. Utility Model Content

[0003] The utility model aims to provide an automatic deviation correction device for a belt filter to solve the problems in the prior art that the center distance of the bearing seat is constantly changing and extending during the deviation correction process, resulting in a high failure rate and a short service life of the deviation correction device.

[0004] To achieve the above purpose, the utility model provides the following solutions:

[0005] The utility model provides an automatic deviation-correcting device for a belt filter, comprising a bracket and a left bearing assembly and a movable bracket which are slidably connected to the bracket in the longitudinal direction; a fixed bracket is rotatably connected to the movable bracket; a right bearing assembly is arranged on the fixed bracket; a deviation-correcting roller which is arranged in the transverse direction has one end fixedly connected to the left bearing assembly and the other end fixedly connected to the right bearing assembly; a deviation-correcting airbag is fixedly arranged on the bracket at both the front and rear sides of the left bearing assembly, and the left bearing assembly can abut against the deviation-correcting airbag.

[0006] Preferably, a protective cover is provided on the side of the left bearing assembly away from the deviation-correcting roller.

[0007] Preferably, a slide groove is provided on the bracket, and the left bearing assembly and the movable bracket are both slidably connected in the slide groove.

[0008] Preferably, a washer is provided on the movable bracket, a pressure cover is provided above the washer, a thrust ball bearing is provided between the washer and the pressure cover, the fixed bracket is provided above the pressure cover, and one end of a bolt without a nut can pass through the fixed bracket, the pressure cover, the washer and the movable bracket in sequence and be threadedly connected with a nut.

[0009] Compared with the prior art, the utility model has achieved the following technical effects:

[0010] The utility model provides an automatic deviation correcting device for a belt filter. When the filter belt deviates laterally, the filter cloth triggers the lever, so that the deviation correcting airbag pushes the left bearing assembly to produce longitudinal displacement, driving the deviation correcting roller to deflect by a certain angle. Due to the axial force of the deviation correcting roller, the right bearing assembly rotates at a small angle on the fixed bracket. Under the friction force of the deviation correcting roller, the deviation of the filter cloth is quickly corrected. When the deviation of the filter cloth disappears, the deviation correcting airbag restores the balance state, the left bearing assembly restores the original position, the deviation correcting roller is parallel to the filter cloth, and the right bearing assembly returns to the initial position under the force of the deviation correcting roller. By enabling the left bearing assembly and the right bearing assembly to slide back and forth in the longitudinal direction on the bracket and enabling the right bearing assembly to rotate, real-time adjustment of the center distance of the bearing seats is achieved, thereby solving the problem of high failure rate and short service life of the deviation correcting device caused by the continuous change and extension of the center distance of the bearing seat during the deviation correction process.
