Problems solved by technology

However, the existing belt filter press generally utilizes the tensioning of the filter screen and the action of the pressure roller to form a filter press effect. During the continuous operation of the filter screen, the filter screen is likely to be damaged due to uneven force and other reasons. Deviation from the original track, which requires the use of correction rollers to correct the deviation of the filter screen
Therefore, in order to realize the tensioning and deviation correction of the filter screen, tensioning rollers and deviation correction rollers are usually installed on the belt filter press. In most cases, the air source is used to drive. The more air source driving points, the greater the gas consumption. , the higher the demand for energy consumption, and the complex structure of the belt machine equipment, the deviation correction device uses the tension force of the filter screen caused by the movement of the deviation correction roller on the filter screen to achieve deviation correction on both sides. Due to the travel limit of the correction roller, the The change of the tension force of the filter is small, and the deviation correction time is long, which is reflected in the low deviation correction speed, which also results in low sensitivity of the deviation correction of the filter screen, and its deviation correction effect is not ideal
In addition, its equipment manufacturing cost and maintenance cost are usually high, which is not conducive to the control of production cost

Embodiment 1

[0030] A kind of tension correction device that present embodiment is used for belt type filter press, such as figure 1 As shown, it includes a tensioning deviation adjustment roller 10, a left deviation correction mechanism and a right deviation correction mechanism, the tension deviation adjustment roller is arranged at one end of the filter screen, and the left deviation correction mechanism and the right deviation correction mechanism are symmetrically arranged on the left and right sides of the filter screen 11, and The left deviation correction mechanism and the right deviation correction mechanism are respectively connected with the left and right ends of the tensioning deviation adjustment roller, and the left deviation correction mechanism and the right deviation correction mechanism are respectively externally connected with an air source mechanism. Among them, along the conveying direction of the filter screen (as shown by the arrow in the figure), the tension adjust...

Embodiment 2

[0035] In this embodiment, a tension correction method for a belt filter press is realized through the tension correction device described in Embodiment 1. Unilateral expansion and contraction, adjust the tension of one side of the filter screen, so as to realize the rectification of the filter screen. For the biased side of the filter screen, by stretching the tension adjustment roller at this end, it will return to the original position after the deviation is corrected. Specifically:

[0036] (1) When the tension of the filter screen needs to be adjusted, the left and right deviation correction mechanisms drive both ends of the tension adjustment roller at the same time, so that the tension adjustment roller can move in translation along the conveying direction of the filter screen; adjust the filter screen When the tension is high, the specific process is as follows:

[0037] In the left correction mechanism, the compressed gas from the air source mechanism enters the left ...

Abstract

The invention discloses a tensioning rectification method and apparatus used for a belt filter press. The method comprises: driving two ends of a tensioning deflection-adjusting roller at the same time through a left rectification mechanism and a right rectification mechanism, and making the tensioning deflection-adjusting roller translate along a conveying direction of a filter screen so as to adjust the tensioning degree of the filter screen. When the filter screen deflects to the left side, the left rectification mechanism drives the left end of the tensioning deflection-adjusting roller for rectification, and when the filter screen deflects to the right side, the right rectification mechanism drives the right end of the tensioning deflection-adjusting roller for rectification. The apparatus includes the tensioning deflection-adjusting roller, the left rectification mechanism, and the right rectification mechanism, wherein the tensioning deflection-adjusting roller is arranged at one end of the filter screen, and the left rectification mechanism and the right rectification mechanism are symmetrically installed at the left and right sides of the filter screen. The left rectification mechanism and the right rectification mechanism are connected to the left and right ends of the tensioning deflection-adjusting roller, respectively, and are externally connected to a gas source mechanism. Through the same mechanism group, tensioning adjustment and rectification of the filter screen can be achieved at the same time, so that the structure of the apparatus is simplified.

Description

technical field [0001] The invention relates to the technical field of sludge dewatering equipment, in particular to a tensioning and deviation correction method and device for a belt filter press. Background technique [0002] In the field of dehydration technology, plate and frame filter press equipment, centrifugal dehydration equipment and belt dehydration equipment are generally used in the prior art, among which belt dehydration equipment is favored by the majority of users because of its continuity, high degree of automation, and power saving. use. However, the existing belt filter press generally utilizes the tensioning of the filter screen and the action of the pressure roller to form a filter press effect. During the continuous operation of the filter screen, the filter screen is likely to be damaged due to uneven force and other reasons. If there is any deviation from the original track, it is necessary to use a correction roller to correct the deviation of the f...
