Description

Technical Field

[0001] The invention belongs to the technical field of mechanical filter pressing and dehydration of materials, and in particular relates to a spatial multi-layer vertical filter pressing and dehydration machine for annular filter cloth. Background Art

[0002] At present, most of the various organic wastes generated in production and life have a moisture content of more than 70% to 80%. To carry out environmental protection management of organic waste and to utilize it as a resource, "turning waste into treasure and turning waste into resources", it is necessary to dehydrate the organic waste, and reducing its moisture content as much as possible is the key. Mechanical dehydration is one of the commonly used dehydration technical means and also the fastest dehydration technical means. Common mechanical equipment used for dehydration of organic waste includes belt filter press dehydrator, plate and frame filter press dehydrator, screw dehydrator, centrifugal dehydrator, vacuum suction filter dehydrator and space multi-layer vertical filter press dehydrator. Since the space multi-layer vertical filter press dehydration can dehydrate most organic wastes with high moisture content to 50% or even below 40%, it has been promoted and applied in the dehydration treatment of organic wastes such as municipal sludge, cassava starch residue, and sugar filter mud.

[0003] However, the spatial multi-layer vertical filter press dehydration machines currently promoted and applied in the market still have many technical problems that need to be improved. For example, some filter cloths are disconnected non-annular filter cloths, and it is impossible to realize continuous dehydration production with cloth feeding on one side and unloading and discharging on the same set of filter cloths at the same time. The degree of automation is low, and there is a certain gap with the actual continuous operation needs. Although some filter cloths have realized continuous dehydration production with cloth feeding on one side and unloading and discharging on the same set of filter cloths, the degree of automation of the equipment has been improved, but the length of the laid filter cloth is severely limited, the filter cloth is easily squeezed by frequent high-pressure machinery, and the service life is relatively short. Frequent replacement and sewing of the interface are required, which affects the overall efficiency of the equipment. In addition, the filter cloth currently used is generally thin and has poor tensile resistance. It is easy to be stretched during use, so that the "fixed-size" filter cloth is constantly stretched during the dehydration production process. In order to maintain a certain tension of the filter cloth, the stroke of the tensioning roller needs to be continuously adjusted, and the number of tensioning rollers needs to be increased when appropriate, which often interrupts production and affects the energy consumption, life and dehydration operation efficiency of the device.

[0004] Therefore, there is an urgent need for a spatial multi-layer vertical filter press dehydrator for annular filter cloth to solve the technical problems existing in the above-mentioned existing spatial multi-layer vertical filter press dehydrator, so as to better help all walks of life to "reduce pollution and carbon emissions" and reduce costs and increase efficiency.

[0080] In this embodiment, optionally, the filter cloth clamping mechanism 72 can also only clamp the upper filter cloth 5 in the clamping space of the filter cloth clamping mechanism 72, and the filter cloth clamping mechanism 72 drives and pulls the upper filter cloth 5, drives the lower filter cloth 6 through the upper filter cloth 5, and synchronously transmits the upper filter cloth 5 to the upper filter cloth stacking box 742, and synchronously transmits the lower filter cloth 6 to the lower filter cloth stacking box 752.

[0081] In this embodiment, optionally, the filter cloth clamping mechanism 72 can also be arranged in an inverted manner, and the lower filter cloth 6 is only clamped 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, drives the upper filter cloth 5 through the lower filter cloth 6, and synchronously transmits the upper filter cloth 5 to the upper upper filter cloth stacking box 742, and synchronously transmits the lower filter cloth 6 to the lower lower filter cloth stacking box 752.

[0082] Embodiment 4

[0083] like Figures 8 to 11 As shown, the annular filter cloth space multi-layer vertical filter press dehydrator of the fourth embodiment of the present invention is similar to the third embodiment, and the difference is only that:

[0084] In order to better arrange the filter press material in the middle of the lower filter cloth 6, and to better align the upper filter cloth 5 and the lower filter cloth 6, and fold the edges through the filter cloth folding mechanism 8 to avoid leakage of the material from the folded edges during the filter press, a correction frame is added and installed, and the correction frame includes an upper filter cloth correction mechanism 9 and a lower filter cloth correction mechanism 10. The upper filter cloth correction mechanism 9 is arranged on the annular loop of the unoverlapped part of the upper filter cloth 5, and includes an upper correction frame 91 and an upper correction thorn surface belt conveyor 92. The upper correction thorn surface belt conveyor 92 is installed at both ends of the upper correction frame 91, and at least one pair of upper correction thorn surface belt conveyors 92 with opposite movement directions are arranged at the upper and lower parts of each end, and the upper filter cloth 5 is arranged between each pair of upper correction thorn surface belt conveyors 92 with opposite movement directions. The lower filter cloth deviation correction mechanism 10 is arranged on the annular loop of the unoverlapped part of the lower filter cloth 6, and includes a lower deviation correction frame 101 and a lower deviation correction thorn surface belt conveyor 102; the lower deviation correction thorn surface belt conveyor 102 is installed at both ends of the lower deviation correction frame 101, and at least one pair of lower deviation correction thorn surface belt conveyors 102 with opposite movement directions are arranged at the upper and lower parts of each end, and the lower filter cloth 6 is arranged between each pair of lower deviation correction thorn surface belt conveyors 102 with opposite movement directions. For example, the upper deviation correction thorn surface belt conveyor 92 is installed at both ends of the upper deviation correction frame 91, and the lower deviation correction thorn surface belt conveyor 102 is installed at both ends of the lower deviation correction frame 101, and three deviation correction thorn surface belt conveyors are respectively installed at the upper and lower positions of each end. For example, one of the upper deviation correction thorn surface belt conveyors 92 is located above the upper filter cloth 5 at this end, and the other two deviation correction thorn surface belt conveyors 92 are located below the upper filter cloth 5 at this end, and are symmetrically arranged along the running direction of the upper filter cloth 5. For another example, one of the lower deflection correction thorn surface belt conveyors 102 is located above the lower filter cloth 6 at this end, and the other two lower deflection correction thorn surface belt conveyors 102 are located below the lower filter cloth 6 at this end, and are symmetrically arranged along the running direction of the lower filter cloth 6. The upper deflection correction frame 91 is connected and installed on the frame 1 between the upper filter cloth buffer device 74 and the filter cloth folding mechanism 8, and the upper filter cloth 5 passes between the upper deflection correction thorn surface belt conveyor 92 and the two upper deflection correction thorn surface belt conveyors 92 symmetrically arranged below. The lower deviation correction frame 101 is connected and installed on the frame 1 between the lower filter cloth buffer device 75 and the material distribution machine 2, and the lower filter cloth 6 passes between the upper lower deviation correction thorn surface belt conveyor 102 and the two lower deviation correction thorn surface belt conveyors 102 symmetrically arranged below, so that when the upper filter cloth 5 or the lower filter cloth 6 deviates to one side, it can be automatically pulled to the other side by the upper deviation correction thorn surface belt conveyor 92 or the lower deviation correction thorn surface belt conveyor 102 and reset to the center position.

[0085] Embodiment 5

[0086] like Figure 12 to Figure 14As shown, the spatial multi-layer vertical filter press dehydrator for annular filter cloth of the fifth embodiment of the present invention is similar to 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 open more stably and reliably after the filtration is completed, so as to better meet the requirements of the filter cloth clamping mechanism 72 to drive and pull the upper filter cloth 5 and / or the lower filter cloth 6, and to remove the filter press material between the upper filter cloth 5 and the lower filter cloth 6 more completely and cleanly, a filter cloth edge spreading mechanism 11 is added and installed. The filter cloth edge spreading mechanism 11 is composed of an edge spreading frame 111 and an edge spreading thorn surface belt conveyor 112, and the edge spreading frame 111 is connected and installed above the superimposed upper filter cloth 5 and the lower filter cloth 6 and is located on the frame 1 between the last filter press hydraulic press 3 and the filter cloth clamping mechanism 72. The edge spreading and thorn surface belt conveyor 112 is installed at both ends of the edge spreading frame 111, with one edge spreading and thorn surface belt conveyor 112 installed at each end, and the movement directions of the edge spreading and thorn surface belt conveyors 112 located at both ends are opposite, and the folded edges of the upper filter cloth 5 and the lower filter cloth 6 are spread out from the inside to the outside to both sides.

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

[0089] In this embodiment, since the lower filter cloth 6 is folded upward to wrap the filter press material behind the cloth, optionally, the width of the upper filter cloth 5 is designed to be smaller than that of the lower filter cloth 6. The filter cloth folding mechanism 8 folds the upper filter cloth 5 and the lower filter cloth 6 more neatly and saves filter cloth material.
