Description

Technical Field

[0001] The present invention relates to the field of sludge treatment, and particularly to a suspension walking device for a filter plate group of a sludge filter press. Background Art

[0002] As an environmental protection device, the main function of a sludge filter press is to pressurize and dehydrate the high-moisture-content sludge generated during the sewage treatment process to make it into a sludge cake with a lower moisture content for transportation and disposal. Traditional plate-and-frame or diaphragm filter presses use hydraulic cylinders to provide the filter plate clamping pressure and squeezing water to provide the power for sludge filtration. The two work together to achieve sludge filtration and dehydration. However, this combination results in a relatively small filtration pressure during the sludge filtration process, which cannot effectively increase the sludge filtration pressure, leading to a high moisture content of the sludge after filtration, or a long treatment cycle and low output, unable to meet the requirements of subsequent sludge resource recycling or terminal disposal, nor the increasing market demand for sludge filtration. The newly emerging piston-type high-pressure filter press on the market can directly filter the raw sludge to a moisture content of less than 50%, but it has relatively high requirements for the cooperation between filter plate groups. Furthermore, it requires the relative position between filter plate groups to be stable during the filtration process. Therefore, it is required that the suspension walking device of the filter plate group can ensure the smooth walking process of the filter plate group without significant left-right swaying, front-back swaying, or rotation with large amplitudes. When the existing mature hanging walking device on the market drives the filter plate group to walk, the left-right swaying, front-back swaying, and rotation of the filter plates are obvious, resulting in a relatively large change in the relative position between the filter plate groups, unable to meet the usage requirements of the filter plate group of the piston-type high-pressure filter press. Summary of the Invention

[0003] In view of the obvious left-right swaying, front-back swaying, and rotation of the filter plates when the existing hanging walking device drives the filter plate group to walk, resulting in a relatively large change in the relative position between the filter plate groups and unable to meet the usage requirements of the filter plate group of the piston-type high-pressure filter press, the present utility model provides a suspension walking device for a filter plate group of a sludge filter press, which restricts and limits the left-right swaying, front-back swaying, and rotation during the walking process of the filter plate group, making the walking of the filter plate group smooth, with a small change in the relative position between the filter plate groups, and meeting the requirement of the piston-type high-pressure filter press for the relative position stability during the filtration process of the filter plate group.

[0004] The technical solution adopted by the utility model is as follows: A suspension walking device for a filter plate group of a sludge filter press, which includes an anti-front-and-back swing hanger and an anti-left-and-right swing hanger. The anti-left-and-right swing hanger is arranged in the middle of the top of the filter cavity plate of the filter plate group, and the anti-front-and-back swing hanger is arranged on the top of the filter press plate. One side of the anti-rotation clamping strip I of the anti-front-and-back swing hanger is arranged in the rectangular cavity of the cross beam I, and the other side is arranged on the side of the top of the filter press plate. One side of the anti-rotation clamping strip II of the anti-left-and-right swing hanger is arranged in the rectangular cavity of the cross beam II, and the other side is arranged on the side of the top of the filter cavity plate. The two rollers I of the anti-front-and-back swing hanger are respectively mounted on the inner guide rails symmetrically arranged on the left and right sides of the suspension beam. The rollers II on both sides of the anti-left-and-right swing hanger are respectively mounted on the outer guide rails on both sides of the bottom of the suspension beam, and the roller III of the anti-left-and-right swing hanger is located at the bottom of the outer guide rails on both sides of the bottom of the suspension beam.

[0005] In the above technical solution, the anti-front-and-back swing hanger includes a cross beam I, an anti-rotation clamping strip I, a roller bracket, a roller I, and a vertical beam. The cross beam I is rectangular and hollow, and the clamping strip I is "L"-shaped. The vertical beam is arranged in the middle above the cross beam I. The two anti-rotation clamping strips I are respectively arranged at both ends of the cross beam I. The two roller brackets are arranged above the cross beam I, respectively on the left and right sides of the vertical beam, and extend obliquely in opposite directions from the cross beam I, one in front and one behind. The two rollers I are respectively arranged in the two roller brackets. The anti-left-and-right swing hanger includes a cross beam II, an anti-rotation clamping strip II, a roller seat, a roller II, and a roller III. The cross beam II is rectangular and hollow, and the anti-rotation clamping strip II is "L"-shaped. The two anti-rotation clamping strips II are symmetrically arranged at both ends above the cross beam II. The two sets of roller seats are symmetrically arranged at both ends above the cross beam II, above the anti-rotation clamping strip II. The roller II is arranged in the groove formed by the rib plate I, rib plate II, and rib plate III of the roller seat, and the roller III is located on the upper surface of the base of the roller seat.

[0006] In the above technical solution, the roller seat includes a base, a rib plate I, a rib plate II, and a rib plate III. The base is fixed on the cross beam II. The rib plate I is vertically arranged in the middle of the base. The rib plate II is arranged at the upper end of the rib plate I and is parallel to the base. The middle of the rib plate III is arranged at the end of the rib plate II and is parallel to the rib plate I. The lowest point of the load-bearing wheel of the roller II is lower than the bottom edge of the rib plate III, and a retaining edge is arranged at one end of the load-bearing wheel close to the rib plate I.

[0007] The beneficial effects of the utility model are as follows: The left-and-right swing, front-and-back swing, and rotation during the walking of the filter plate group are restricted, so that the filter plate group walks smoothly, the relative position change between the filter plate groups is small, and the requirement for the relative position stability of the filter plate group during the pressure filtration process of the piston-type high-pressure filter press is met.

[0021] The left-and-right swing prevention hanger 2 includes a cross beam II 2-1, an anti-rotation clamping strip II 2-2, a roller seat 2-3, a roller II 2-4, and a roller III 2-5; roller seats 2-3 are symmetrically installed at both ends above the cross beam II 2-1, and the roller seats 2-3 are located above the anti-rotation clamping strip II 2-2. The roller seat 2-3 includes a base 2-3-1, a rib plate I 2-3-2, a rib plate II 2-3-3, and a rib plate III 2-3-4. The base 2-3-1 is installed on the cross beam II 2-1. The rib plate I 2-3-2 is vertically arranged in the middle of the base 2-3-1. The rib plate II 2-3-3 is arranged at the upper end of the rib plate I 2-3-2 and is parallel to the base 2-3-1. The middle of the rib plate III 2-3-4 is arranged at the end of the rib plate II 2-3-3 and is parallel to the rib plate I 2-3-2; the lowest point of the load-bearing wheel 2-4-1 of the roller II 2-4 is lower than the bottom edge of the rib plate III 2-3-4, and a retaining edge 2-4-2 is arranged at one end of the load-bearing wheel 2-4-1 close to the rib plate I 2-3-2; the roller II 2-4 is installed in the groove formed by the rib plate I 2-3-2, the rib plate II 2-3-3, and the rib plate III 2-3-4 of the roller seat 2-3, and the roller III 2-5 is installed on the upper surface of the base 2-3-1 of the roller seat 2-3.

[0022] Both the cross beam I 1-1 and the cross beam II 2-1 are rectangular and hollow, and both the anti-rotation clamping strip I 1-2 and the anti-rotation clamping strip II 2-2 are "L"-shaped;

[0023] The front-and-back swing prevention hanger 1 is fixed to the top of the filter plate 3-1 of the filter plate group 3. One side of the anti-rotation clamping strip I 1-2 of the front-and-back swing prevention hanger 1 is fixed in the rectangular cavity of the cross beam I 1-1, and the other side is fixed to the top side of the filter plate 3-1 to prevent rotation between the cross beam I 1-1 and the filter plate group 3; the left-and-right swing prevention hanger 2 is arranged on the top of the filter cavity plate 3-2 of the plate group 3. One side of the anti-rotation clamping strip II 2-2 of the left-and-right swing prevention hanger 2 is fixed in the rectangular cavity of the cross beam II 2-1, and the other side is fixed to the top side of the filter cavity plate 3-2 to prevent rotation between the cross beam II 2-1 and the filter plate group 3.

[0024] The anti-front-and-back swing hanger 1 and the anti-left-and-right swing hanger 2 act together to hang the filter plate group 3 on the suspension beam 4 of the filter press; two rollers I1-4 of the anti-front-and-back swing hanger 1 are installed on the inner guide rails 4-1 on the left and right symmetry of the suspension beam 4; two rollers II2-4 on both sides of the anti-left-and-right swing hanger 2 are respectively erected on the outer guide rails 4-2 on both sides of the bottom of the suspension beam 4, and the roller III2-5 of the anti-left-and-right swing hanger 2 is located at the bottom of the outer guide rails 4-2 on both sides of the bottom of the suspension beam 4. Only an installation clearance is reserved between the outer guide rails 4-2 on both sides of the bottom of the suspension beam 4 and the roller III2-5 of the anti-left-and-right swing hanger 2.

[0025] During the extrusion process of multiple groups of filter plate groups 3, the force on the filter plate group 3 is very complex. When the pressures on the left and right sides of the filter plate group 3 are unbalanced, the filter plate group 3 has a tendency to rotate. At this time, the rib plate III2-3-4 of the roller seat 2-3 of the left and right anti-swing hangers 2 can ensure that the filter plate group 3 only rotates slightly, so that the relative position change between the filter plate groups 3 does not affect the pressure filtration; when the filter plate group 3 is subjected to a force to the left or right on the upper or lower part, the filter plate group 3 has a tendency to swing left and right. The rib plate III2-3-4 of the roller seat 2-3 of the left and right anti-swing hangers 2 can effectively prevent the filter plate group 3 from swinging left and right, only producing a slight left and right swing, and the relative position change between the filter plate groups 3 does not affect the pressure filtration; when the filter plate group 3 is subjected to a force forward or backward on the upper and lower parts, the filter plate group 3 has a tendency to swing forward or backward. At this time, the two inner guide rails 4-1 on the suspension beam 4 and the two rollers I1-4 of the anti-front-and-back swing hanger 1 located in the front and rear directions respectively interact to prevent the filter plate group 3 from swinging forward or backward; when the filter plate group 3 is subjected to an upward force, the two rollers III2-5 of the anti-left-and-right swing hanger 2 can effectively prevent the filter plate group 3 from moving upward. The relative position change between the filter plate groups 3 does not affect the pressure filtration, and it is ensured that the filter plate group 3 can still move forward and backward smoothly after a slight upward offset; the two rollers I1-4 of the anti-front-and-back swing hanger 1 and the two rollers II2-4 of the anti-front-and-back swing hanger 1 act together to bear the weight of the filter plate group, the weight of the sludge and the downward external force.
