[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0025] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0026] Example 1, reference Figure 1 , which is the first embodiment of the present invention, provides a filter cloth correction device for a vacuum belt dehydrator, and the device includes a mounting unit 100 and a correction unit 200.

[0027] The installation unit 100 includes a support frame 101 for installing the deviation correction unit 200;

[0028] The correction unit 200 includes an expansion component 201 arranged at both ends of the support frame 101, and an air intake pipe 202 respectively connected to the expansion component 201, wherein the expansion component 201 can be expanded by inflation, and the outer side can be displaced when it expands, thereby achieving position adjustment.

[0029] Among them, the installation unit 100 also includes a support shaft 102 arranged between two expansion components 201, and the support shaft 102 is installed with a correction roller and matching bearings. The expansion component 201 is inflated or deflated to change its own volume, thereby changing the space occupied, and further changing the position of the support shaft 102 to realize the movement and adjustment of the correction roller and the matching bearings.

[0030] The expansion component 201 can be made of rubber and can be inflated into a rubber ball, and the support shaft 102 is installed between two rubber balls. The expansion component 201 can support the support shaft 102.

[0031] Furthermore, the support frame 101 is U-shaped, and two expansion assemblies 201 are respectively installed at two parallel ends of the support frame 101, wherein the bottom of the support frame 101 is horizontal and the two sides are vertical, so that the bottom of the support frame 101 is kept horizontally installed, and the expansion assemblies 201 are fixedly installed through the two sides of the support frame 101, so that the two expansion assemblies 201 are opposite and have the same height;

[0032] At this time, the support shaft 102 is installed between the two expansion components 201 and maintained in a horizontal state to ensure that the deviation correction rollers and the matching bearings on the support shaft 102 remain horizontal. When the filter cloth deviates, the movement of the support shaft 102 can be controlled by inflating or deflating the two expansion components 201, thereby controlling the movement of the bearings and achieving the offset adjustment of the filter cloth.

[0033] During use, when the filter cloth is offset, the expansion component 201 is inflated in the offset direction of the filter cloth, and the air is deflated toward the other expansion component 201, so that the inflated expansion component 201 drives the support shaft 102 to move in the direction of the deflated expansion component 201, thereby achieving the offset adjustment of the filter cloth.

[0034] Example 2, reference Figure 2 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the correction unit 200 also includes an adjustment support assembly 203 arranged at the bottom of the support frame 101, which is used to adjust the support frame 101, wherein the expansion assembly 201 is used to fine-tune the support shaft 102, and the adjustment support assembly 203 is used to coarse-tune the support frame 101.

[0035] Furthermore, the adjustable support assembly 203 includes a support platform 203a arranged below the support frame 101, an expansion assembly 204 arranged on both sides of the support platform 203a, and an intake pipe 205 respectively connected to the two expansion assemblies 204, wherein the expansion assembly 204 can change in volume as the intake pipe 205 is inflated or deflated, thereby changing the space occupied by it.

[0036] The expansion component 204 can be an inflatable rubber ball made of rubber, and its support platform 203a is installed between two rubber balls. The expansion component 204 can support the support platform 203a. At the same time, when the expansion component 204 is inflated or deflated, it can drive the support platform 203a to move, thereby driving the support frame 101 to move as a whole, thereby realizing the offset adjustment of the filter cloth.

[0037] Furthermore, the installation unit 100 also includes a second support frame 103 arranged outside the two second expansion components 204, wherein the second support frame 103 is U-shaped, and the two second expansion components 204 are respectively installed at two parallel ends of the second support frame 103.

[0038] The bottom of the second support frame 103 is horizontal, and the two ends are vertical. The two expansion components 204 are respectively installed at the two ends of the second support frame 103, but the heights of the two expansion components 204 are kept the same, thereby ensuring that the support platform 203a and the first support frame 101 are in a horizontal state.

[0039] Furthermore, the support platform 203a includes a crossbar 203a-1 disposed between the two expansion assemblies 204, and two vertical bars 203a-2 disposed on the crossbar 203a-1 and connected to the support frame 101. The support crossbar 203a-1 is installed between the two expansion assemblies 204 and maintained horizontally, and the two vertical bars 203a-2 are used to be installed on the support frame 101 to maintain the level of the support frame 101.

[0040] When the filter cloth is offset, the position can be adjusted by inflating or deflating the expansion component 204, or by inflating or deflating the expansion component 1 201. The combination of the expansion component 1 201 and the expansion component 2 204 can provide a wider range of position adjustment and more adjustment options.

[0041] The remaining structures are the same as those of Example 1.

[0042] The use process is as follows: when the filter cloth is offset, the expansion component 201 is inflated in the offset direction of the filter cloth, and the air is deflated toward the other expansion component 201, so that the inflated expansion component 201 drives the support shaft 102 to move in the direction of the deflated expansion component 201, thereby achieving the offset adjustment of the filter cloth;

[0043] Alternatively, the filter cloth offset adjustment is achieved by inflating the second expansion component 204 in the offset direction of the filter cloth and deflating the second expansion component 204 at the same time, so that the inflated second expansion component 204 drives the support platform 203a to move in the direction of the deflated second expansion component 204;

[0044] Alternatively, the expansion component 204 and the expansion component 1 201 in the direction of filter cloth offset are inflated at the same time, and the other expansion component 204 and the expansion component 1 201 are deflated at the same time, and the support platform 203a and the support frame 1 101 are moved in the deflated direction at the same time to achieve filter cloth offset adjustment.

[0045] Example 3, reference Figure 1 and Figure 2 , which is the third embodiment of the present invention, and this embodiment is different from the second embodiment in that: the expansion assembly 1 201 includes two mounting flanges 1 201a, two air bags 1 201b arranged between the two mounting flanges 1 201a, and a partition 1 201c arranged between the two air bags 1 201b, wherein the two air bags 1 201b are connected to each other, and the two air bags 1 201b can be inflated through the air inlet pipe 1 202 to expand them, thereby driving the mounting flanges 1 201a inside the two air bags 1 201b to move;

[0046] The support shaft 102 is installed between two mounting flanges 201a, and the other two mounting flanges 201a are installed and fixed to the support frame 101.

[0047] The expansion assembly 204 includes two mounting flanges 204a, two airbags 204b disposed between the two mounting flanges 204a, and a partition 204c disposed between the two airbags 204b; wherein the two airbags 204b are connected to each other, and the two airbags 204b can be inflated through the air inlet pipe 205 to expand, thereby driving the mounting flanges 204a inside the two airbags 204b to move;

[0048] The cross bar 203a - 1 is installed between two second mounting flanges 204a , and the other two second mounting flanges 204a are installed and fixed to the second support frame 103 .

[0049] Furthermore, the expansion stroke of the two airbags 1 201b is 200mm, the expansion stroke of the two airbags 204b is 400mm, the total expansion stroke of the expansion component 1 201 and the expansion component 2 204 is 600mm, and the expansion speed of the airbag 1 201b is less than the maximum expansion speed of the airbag 2 204b.

[0050] The material of airbag 1 201b and airbag 2 204b is made of rubber material. The expansion stroke of airbag 1 201b is smaller, so the filter cloth can be fine-tuned. The expansion stroke of airbag 2 204b is larger, so the filter cloth can be thickened. When adjusting the offset of the filter cloth, the appropriate adjustment method is selected according to the offset degree of the filter cloth.

[0051] The remaining structure is the same as that of Example 2.

[0052] The use process is as follows: when the filter cloth deviates, the deviation is corrected according to the degree of deviation of the filter cloth. When the deviation of the filter cloth is small, the airbag 1 201b is inflated in the direction of the deviation of the filter cloth, and the airbag 1 201b is deflated at the same time, so that the inflated airbag 1 201b drives the support shaft 102 to move in the direction of the deflated airbag 1 201b, thereby realizing the deviation adjustment of the filter cloth;

[0053] When the filter cloth is greatly offset, first, inflate airbag 204b in the offset direction of the filter cloth, and at the same time, deflate the other airbag 204b, so that the inflated airbag 204b drives the support platform 203a to move in the direction of the deflated airbag 204b, and perform preliminary roughing. Then, inflate airbag 1 201b in the offset direction of the filter cloth, and at the same time, deflate the other airbag 1 201b, so that the inflated airbag 1 201b drives the support shaft 102 to move in the direction of the deflated airbag 1 201b, thereby realizing the offset adjustment of the filter cloth.
