In order to enable those skilled in the art to better understand the scheme of the present application, the present application will be described in further detail with reference to the accompanying drawings and the detailed description.

Referring to fig. 1 to 4, fig. 1 is a schematic structural diagram of an embodiment of a belt filter press provided in the present application; FIG. 2 is an enlarged view of A in FIG. 1; FIG. 3 is a front view of the belt filter press of FIG. 1; fig. 4 is a schematic structural diagram of the deviation rectifying mechanism in fig. 1.

The belt filter press structurally comprises an upper mounting frame 2 and a lower mounting frame 3 as shown in figure 1. The upper press roll group is arranged at the lower side of the upper mounting frame 2, and the lower press roll group is arranged at the upper side of the lower mounting frame 3. Two sets of guipure 1 twine respectively in the periphery of last compression roller set and lower compression roller set, go up the compression roller set and form between the compression roller set down and walk the material clearance, the material passes through from walking in the material clearance, goes up compression roller set and lower compression roller set and extrudees the material through guipure 1, the moisture in the discharge material. The structures of the upper press roll group, the lower press roll group, and the mesh belt 1 can refer to the prior art, and are not described in detail herein.

The upper side of the upper mounting frame 2 is provided with a deviation correcting mechanism 5, and the lower side of the lower mounting frame 3 is also provided with a deviation correcting mechanism 5. The present embodiment will be described by taking an example in which the deviation correcting mechanism 5 is mounted on the upper mounting frame 2. The deviation correcting mechanism 5 comprises a deviation correcting roller 51 and a deviation correcting seat, and the deviation correcting seat comprises a rotating support 56 and a sliding support 57. The rotary support 56 and the slide support 57 are respectively provided on both sides of the upper mounting frame 2, and the webbing 1 is located between the rotary support 56 and the slide support 57. The rectification roller 51 is disposed inside the loop formed by the mesh belt 1, and the rectification roller 51 is combined with the upper press roller set to tension the mesh belt 1. The first end of the rectification roller 51 is rotatably connected with the rotating support 56 by adopting a mounting clamp and the like, and the rotating shaft is vertical to the plane of the mounting rack 2. The sliding support 57 is wrapped by sliding rails parallel to the side beams of the upper mounting frame 2, the second end of the rectification roller 51 can be lapped on the sliding rails, and the tension of the mesh belt 1 ensures that the rectification roller 51 is always attached to the sliding rails. The deviation rectifying mechanism 5 further comprises a detecting part and an adjusting part, wherein the adjusting part is arranged on the sliding rail of the sliding support 57, and the adjusting part is connected with the detecting part. The detecting section is for detecting the deviation of the mesh belt 1, and when the detecting section detects the deviation, the adjusting section pushes the second end of the deviation correcting roller 51 to rotate around the rotating shaft of the rotating support 56, thereby changing the angle of the deviation correcting roller 51. When the angle of the correction roller 51 is changed, the force acting between the correction roller and the mesh belt 1 increases, and the mesh belt 1 tends to be adjusted to a position where the force acting is small. Finally, the mesh belt 1 is adjusted to the position perpendicular to the deviation rectifying roller 51, and online deviation rectification of the mesh belt 1 is achieved. The detection part can refer to an infrared sensor, a vision sensor and the like in the prior art, and the adjustment part can refer to an air cylinder and the like in the prior art, which are not described in detail herein.

In some embodiments, the adjustment feature is a deskew air bag 52. As shown in fig. 2 and 4, in the sliding support 57, the two ends of the upper side of the sliding rail are both provided with a limiting plate, the second end of the rectification roller 51 is arranged in the middle of the sliding support 57, and a rectification air bag 52 is arranged between the two limiting plates and the second end of the rectification roller 51. The side of the rectification air bag 52 close to the rectification roller 51 is connected with the installation card, and the second end of the rectification roller 51 is arranged in the installation card. When the deviation rectifying air bags 52 on one side of the deviation rectifying rollers 51 are inflated, the volume of the deviation rectifying air bags is expanded, and the deviation rectifying rollers 51 are further pushed to slide along the sliding rails.

In some embodiments, the deviation rectification mechanism 5 further comprises a two-position three-way mechanical valve 53. As shown in FIG. 4, the two-position three-way mechanical valve 53 comprises a valve body and an offset detection rod 54, two outlets of the valve body are respectively connected with the deviation rectifying airbags 52 at two sides of the second end of the deviation rectifying roller 51, and an inlet of the valve body is connected with an air source 55. The gas source 55 may be embodied as a compressor or blower, etc. The offset detection rod 54 is connected to the spool of the two-position three-way mechanical valve 53 and can push the spool to move. The offset detection rod 54 is attached to one side of the mesh belt 1, and when the mesh belt 1 is offset, the angle of the offset detection rod 54 is changed, so that the valve core is driven to move. After the valve core moves, the two deviation rectifying airbags 52 on the two sides of the second end of the deviation rectifying roller 51 change at most, and then the deviation rectifying roller 51 is pushed to slide along the sliding rail. For example, when the webbing 1 is shifted to the left, one correction air bag 52 is inflated and the other correction air bag 52 is deflated, so that the correction roller 51 is shifted from the position perpendicular to the moving direction of the webbing 1. At this time, the frictional force applied to the correction roller 51 by the mesh belt 1 is perpendicular to the correction roller 51, and thus the frictional force has a component force to the left, and the reaction force applied to the mesh belt 1 by the correction roller 51 generates a component force to the right, which moves the mesh belt 1 to the right, thereby returning to the normal position. The connection between the two-position three-way mechanical valve 53 and the offset detection rod 54 can refer to a lever mechanical valve in the prior art, and is not described in detail herein.

The adjustable supporting mechanism 4 comprises a guide rod 42 and a spring 41, wherein the guide rod 42 penetrates through the through holes of the upper mounting seat 21 and the lower mounting seat 31 and is fixedly connected with the lower mounting seat 31 in a bolt connection or welding mode and the like. The spring 41 is fitted around the outer periphery of the guide rod 42 and is disposed between the upper mount 21 and the lower mount 31. The spring 41 is in a compressed state and the force of the spring 41 forms a support for the upper mounting frame 2. The upper part of the guide rod 42 is provided with a positioning nut 43, and the width of the feeding gap can be adjusted by adjusting the position of the positioning nut 43. Of course, the user may also use other structures as the adjustable supporting mechanism 4 according to the requirement, such as a screw pair, an air cylinder, or a hydraulic cylinder, and the like, which is not limited herein.

In some embodiments, the width of the feeding gap is adjustable within the range of 2-20mm, and the material can be extruded into a mud cake with the thickness of 2-20mm after passing through the feeding gap. When the mesh belt 1 is damaged, only the positioning nut 43 needs to be loosened, so that the mesh belt 1 lightly penetrates through the end part of the upper compression roller set or the lower compression roller set, and then the joint is connected, and the replacement work can be completed. After the width of the feeding gap is subsequently adjusted, the normal use of the belt filter press can be recovered, the replacement difficulty of the mesh belt 1 is reduced, and the replacement efficiency is improved.
