Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of material mechanical filter pressing dewatering, and particularly relates to a space multi-layer vertical filter pressing dewatering machine for annular filter cloth. BACKGROUND

[0002] At present, most of the various organic wastes generated in production and life have a water content of 70% to 80% or more. In order to treat and utilize the organic wastes, it is necessary to dewater the organic wastes, and the key is to reduce the water content as much as possible. Mechanical dewatering is one of the commonly used dewatering techniques and the most efficient dewatering technique. Common mechanical devices for dewatering organic wastes include belt filter pressing dewatering machines, plate and frame filter pressing dewatering machines, stacked screw dewatering machines, centrifugal dewatering machines, vacuum suction filter dewatering machines, and space multi-layer vertical filter pressing dewatering machines. Since the space multi-layer vertical filter pressing dewatering machine can dewater most of the high-water-content organic wastes to 50% or even below 40%, it has been popularized and applied in the dewatering treatment of municipal sludge, cassava starch residue, sugar filter mud and other organic wastes.

[0003] However, the space multi-layer vertical filter pressing dewatering machines popularized and applied in the market still have many technical problems that need to be improved. For example, some filter cloths are disconnected and are not annular, and continuous dewatering production cannot be realized on the same set of filter cloths with one side feeding and the other side discharging, and the degree of automation is low, which is not consistent with the demand for continuous operation. Although some filter cloths realize continuous dewatering production on the same set of filter cloths with one side feeding and the other side discharging, the degree of automation of the equipment has improved, but the length of the filter cloth is severely limited, the filter cloth is easily squeezed by frequent high-pressure machinery, the service life is relatively short, and the filter cloth needs to be replaced and spliced frequently, which affects the overall efficiency of the equipment. In addition, the filter cloth used at present is generally thin and has poor tensile resistance, which is easily elongated during use, so that the "fixed size" filter cloth is continuously elongated during dewatering production. In order to maintain a certain tension of the filter cloth, the stroke of the tensioning roller needs to be adjusted constantly, and the number of tensioning rollers needs to be increased at appropriate times, which often causes production interruption, affecting the energy consumption, service life and dewatering efficiency of the device.

[0004] Therefore, there is an urgent need for a space multi-layer vertical filter pressing dewatering machine for annular filter cloth to solve the above technical problems of the existing space multi-layer vertical filter pressing dewatering machine and better help various industries to reduce pollution and carbon emissions and reduce costs and increase efficiency.

The filter cloth clamping mechanism 72 drives and pulls the upper filter cloth 5, which in turn drives the lower filter cloth 6, and synchronously transmits the upper filter cloth 5 to the upper filter cloth stacking box 742 above, and synchronously transmits the lower filter cloth 6 to the lower filter cloth stacking box 752 below.

[0081] In this embodiment, optionally, the filter cloth clamping mechanism 72 can also be set up in an inverted manner, clamping only the lower filter cloth 6 in the clamping space of the filter cloth clamping mechanism 72. The filter cloth clamping mechanism 72 drives and pulls the lower filter cloth 6, which in turn drives the upper filter cloth 5, and synchronously transmits the upper filter cloth 5 to the upper filter cloth stacking box 742 above, and synchronously transmits the lower filter cloth 6 to the lower filter cloth stacking box 752 below.

[0082] Example 4

[0083] like Figure 8 to Figure 11 As shown, the spatial multi-layer vertical filter press dewatering machine for annular filter cloth in Embodiment 4 of the present invention is similar to that in Embodiment 3, except that:

[0084] In order to better arrange the filter material to the center position of the lower filter cloth 6, and better align the upper filter cloth 5 and the lower filter cloth 6, and fold the edge through the filter cloth folding mechanism 8, avoid the material leakage "running material" from the edge when filter pressing, add and install the deviation correction rack, the deviation correction rack includes the upper filter cloth deviation correction mechanism 9 and the lower filter cloth deviation correction mechanism 10. The upper filter cloth deviation correction mechanism 9 is arranged on the annular loop of the non-overlapping part of the upper filter cloth 5, including the upper deviation correction rack 91 and the upper deviation correction ratchet belt machine 92, the upper deviation correction ratchet belt machine 92 is installed at both ends of the upper deviation correction rack 91, at least one pair of upper deviation correction ratchet belt machines 92 with opposite movement directions are arranged at the upper part and the lower part of each end, and the upper filter cloth 5 is arranged between each pair of upper deviation correction ratchet belt machines 92 with opposite movement directions. The lower filter cloth deviation correction mechanism 10 is arranged on the annular loop of the non-overlapping part of the lower filter cloth 6, including the lower deviation correction rack 101 and the lower deviation correction ratchet belt machine 102; the lower deviation correction ratchet belt machine 102 is installed at both ends of the lower deviation correction rack 101, at least one pair of lower deviation correction ratchet belt machines 102 with opposite movement directions are arranged at the upper part and the lower part of each end, and the lower filter cloth 6 is arranged between each pair of lower deviation correction ratchet belt machines 102 with opposite movement directions. For example, the upper deviation correction ratchet belt machine 92 is installed at both ends of the upper deviation correction rack 91, and the lower deviation correction ratchet belt machine 102 is installed at both ends of the lower deviation correction rack 101, three deviation correction ratchet belt machines are arranged at the upper part and the lower part of each end respectively. For example, one of the upper deviation correction ratchet belt machines 92 is located above the upper filter cloth 5 at the end, and the other two upper deviation correction ratchet belt machines 92 are located below the upper filter cloth 5 at the end, and are symmetrically arranged along the running direction of the upper filter cloth 5. For another example, one of the lower deviation correction ratchet belt machines 102 is located above the lower filter cloth 6 at the end, and the other two lower deviation correction ratchet belt machines 102 are located below the lower filter cloth 6 at the end, and are symmetrically arranged along the running direction of the lower filter cloth 6. The upper deviation correction rack 91 is connected and installed on the rack 1 between the upper filter cloth buffer device 74 and the filter cloth folding mechanism 8, and the upper filter cloth 5 passes through between the upper deviation correction ratchet belt machine 92 at the top and the two symmetrically arranged lower deviation correction ratchet belt machines 92 at the bottom. The lower deviation correction rack 101 is connected and installed on the rack 1 between the lower filter cloth buffer device 75 and the cloth machine 2, and the lower filter cloth 6 passes through between the upper deviation correction ratchet belt machine 102 at the top and the two symmetrically arranged lower deviation correction ratchet belt machines 102 at the bottom, so that when the upper filter cloth 5 or the lower filter cloth 6 deviates to one side, it can be automatically pulled and reset to the center position by the upper deviation correction ratchet belt machine 92 or the lower deviation correction ratchet belt machine 102.

[0085] Example five

[0086] As Figure 12 to Figure 14As shown, the space multi-layer vertical filter press of the fifth embodiment of the present application is similar to that of the fourth embodiment, and the difference is only that:

[0087] In order to make the folded edges of the upper filter cloth 5 and the lower filter cloth 6 more stable and reliable after the filter pressing is completed, so as to better meet the driving and traction of the filter cloth clamping mechanism 72 on the upper filter cloth 5 or / and the lower filter cloth 6, and more completely and cleanly unload the filter pressing material between the upper filter cloth 5 and the lower filter cloth 6, a filter cloth edge unfolding mechanism 11 is additionally provided and installed. The filter cloth edge unfolding mechanism 11 is composed of an edge unfolding frame 111 and an edge unfolding ratchet belt machine 112. The edge unfolding frame 111 is connected and installed above the superimposed upper filter cloth 5 and lower filter cloth 6 and located on the frame 1 between the last filter pressing hydraulic machine 3 and the filter cloth clamping mechanism 72. The edge unfolding ratchet belt machine 112 is installed at both ends of the edge unfolding frame 111, one at each end, and the movement directions of the edge unfolding ratchet belt machines 112 at both ends are opposite, unfolding the folded edges of the upper filter cloth 5 and the lower filter cloth 6 from inside to outside to both sides.

[0088] In order to reduce the tension on the single point of the driving mechanism 71 of the filter cloth traction system 7 and the upper filter cloth 5 or / and the lower filter cloth 6, and improve the service life of the upper filter cloth 5 and the lower filter cloth 6, in this embodiment, the redirecting roller 73 is optionally replaced by a power roller 731.

[0089] In this embodiment, since the filter pressing material is wrapped by the folded edges of the lower filter cloth 6 upwards after the cloth, optionally, the width of the upper filter cloth 5 is designed to be smaller than that of the lower filter cloth 6, and the filter cloth folding mechanism 8 folds the edges of the upper filter cloth 5 and the lower filter cloth 6 more neatly and saves more filter cloth material.

[0090] The above is only an optional embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as an optional embodiment, it is not intended to limit the present application. Any skilled person in the art can make some changes or modifications to the above disclosed technical content without departing from the scope of the technical solution of the present application, and equivalent embodiments with equivalent changes are equivalent. Any simple modification, equivalent change and modification of the above embodiments based on the technical essence of the present application are still within the scope of the technical solution of the present application.
