Description

Technical Field

[0001] The utility model relates to the technical field of filter press equipment, in particular to a filter cloth folding and cloth uniformity auxiliary structure and a filter cloth folding device. Background Art

[0002] In the process of folding the filter cloth using a filter press, the filter cloth roll will first be installed at the unwinding place of the filter press, and then the filter cloth will be conveyed out through the feed roller, pressure roller, receiving roller and tensioning roller; at the tail of the filter press, the filter cloth is clamped by the pressure roller and the supporting roller. The pressure roller is an electric roller and rotates at a constant speed, driving the clamped filter cloth forward, and the pressure roller and the supporting roller are pushed by the cylinder to move back and forth horizontally to realize the folding of the filter cloth.

[0003] When driven by a cylinder, due to the compressibility of the gas, the speed of the cylinder movement cannot be uniform, while the pressure roller is uniform, resulting in the shape of the filter cloth being irregular when folded, affecting the uniform laying of subsequent sludge, and ultimately affecting the sludge filtration efficiency and quality of the filter press. Utility Model Content

[0004] Aiming at the technical problem that the existing filter cloth reciprocating folding is indirectly driven by a cylinder and the filter cloth folding shape is not standardized and neat, the utility model provides a filter cloth folding uniform auxiliary structure and a filter cloth folding device.

[0005] The technical solution of the utility model to solve the above technical problems is as follows:

[0006] On the one hand, the utility model provides a filter cloth folding and cloth uniformity auxiliary structure, which is used for installing a supporting roller and a pressing roller for clamping the filter cloth, including two base frames, a motor installed on one of the base frames, two groups of sprocket assemblies respectively installed on the two base frames, and two sliders respectively used for rotating and connected to the two ends of the supporting roller and the pressing roller, the driving end of the motor is simultaneously transmission-connected to the two groups of the sprocket assemblies, the two sliders are respectively connected to the two groups of the sprocket assemblies, the two sliders are respectively slidably connected to the two base frames, and the sliding direction is perpendicular to the supporting roller and the pressing roller.

[0007] The beneficial effects of the utility model are as follows: a motor is used to drive two groups of sprocket wheel assemblies to rotate, so that the slider moves synchronously, driving the support roller and the pressure roller to move back and forth, thereby completing the folding action of the filter cloth; during the folding process, the slider moves at a uniform speed, so that the filter cloth is folded and laid evenly, thereby improving the existing technical problem that the reciprocating folding of the filter cloth is indirectly driven by a cylinder and the folding shape of the filter cloth is not standardized and neat.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, the sprocket assembly includes a driving chain and a driven chain, both of which are annular and parallel to each other. The driving end of the motor drives the two driving chains to rotate synchronously.

[0011] Furthermore, the sliding block is provided with a sliding groove, the groove length direction of the sliding groove is perpendicular to the length direction of the driven chain, and the chain shaft is slidably connected to the sliding groove.

The motor realizes the reciprocating motion of the slider while operating in the same direction, thereby reducing the manufacturing cost.

[0013] Furthermore, the sprocket assembly also includes two driving sprockets, two mounting plates fixed to the base frame and two driven sprockets, the two driving sprockets are meshed with the inner side of the driving chain, the two driven sprockets are meshed with the inner side of the driven chain, two of the driving sprockets belonging to the two groups of sprocket assemblies are simultaneously transmission-connected to the driving end of the motor, and the other driving sprocket of the same group of sprocket assemblies is coaxial with one of the driven sprockets and is simultaneously mounted on one of the mounting plates, and the other driven sprocket is mounted on the other mounting plate.

[0014] The beneficial effect of adopting the above further scheme is: the active sprocket is driven by the motor to rotate, which drives the two driven chains to rotate, thereby driving the two sliders to move back and forth along the straight direction of the two driven sprockets at the same time, solving the problem of uneven reciprocating speed of the original cylinder and achieving the effect of uniform folding and laying of the filter cloth.

[0015] Furthermore, both mounting plates are fixed with double-ended screws, both ends of which are threadedly connected with nuts, and one end is mounted on the mounting plate, the other end of one of the double-ended screws is simultaneously rotationally connected to the other driving sprocket and one of the driven sprockets located on the coaxial line, and the other end of the other double-ended screw is rotationally connected to the other driven sprocket.

[0016] The beneficial effect of adopting the above further solution is that the sprocket can be quickly disassembled and assembled by using the double-headed screw and the nut.

[0017] Furthermore, a strip hole is provided on the mounting plate away from the driving sprocket, the length direction of the strip hole is parallel to the arrangement direction of the two driven sprockets, and one end of the double-headed screw corresponding to the mounting plate passes through the strip hole.

[0018] The beneficial effect of adopting the above further solution is that the double-headed screw rod can be installed through the strip hole, and the position of the double-headed screw rod can be adjusted by using the strip hole to adjust the tension of the driven chain.

[0019] Furthermore, a protective plate is provided at the upper end of the mounting plate, one end of the protective plate is fixed to the mounting plate, and the other end of the protective plate is located above the driven sprocket.

[0020] The beneficial effect of adopting the above further solution is that the driven sprocket is shielded and protected by the protective plate.

[0021] Furthermore, the driving end of the motor is connected to a shaft rod, which is rotatably connected to the base frame, and one end of the shaft rod is connected to the driving end of the motor, and the other end of the shaft rod is simultaneously transmission-connected to the two groups of sprocket assemblies.

[0047] On the one hand, the utility model provides a filter cloth folding and cloth uniformity auxiliary structure, as described in detail below.

[0048] Example 1

[0049] like Figures 1 to 4 A filter cloth folding and cloth uniformity auxiliary structure is used to install a supporting roller 1 and a pressing roller 2 for clamping the filter cloth, including two base frames 3, a motor 4 installed on one of the base frames 3, two groups of sprocket assemblies 5 respectively installed on the two base frames 3, and two sliders 6 respectively used for rotating and connected to the two ends of the supporting roller 1 and the pressing roller 2, the driving end of the motor 4 is simultaneously connected to the two groups of sprocket assemblies 5, the two sliders 6 are respectively connected to the two groups of sprocket assemblies 5, the two sliders 6 are respectively connected to the two base frames 3 for sliding connection, and the sliding direction is perpendicular to the supporting roller 1 and the pressing roller 2.

[0050] The beneficial effects of this embodiment are: the motor 4 is used to indirectly drive the two groups of sprocket assemblies 5 to rotate, so that the slider 6 moves synchronously, driving the support roller 1 and the pressure roller 2 to move back and forth, and completing the folding action of the filter cloth; during the folding process, the slider 6 moves at a uniform speed, so that the filter cloth is folded and laid evenly, thereby improving the existing technical problem that the reciprocating folding of the filter cloth is indirectly driven by a cylinder, and the folding shape of the filter cloth is not standardized and neat.

[0051] As a specific solution of the above embodiment, the base frame 3 is made of square steel, and two base frames 3 are arranged in parallel; the motor 4 is a reduction motor. Both ends of the support roller 1 and the nip roller 2 are rotatably connected to the slider 6 through bearings, and the nip roller 2 is an electric roller, one end of which is energized to realize the rotation and stop of the nip roller 2.

[0052] Example 2

[0053] like Figures 1 to 8On the basis of Example 1, the sprocket assembly 5 includes a driving chain 54 and a driven chain 55, both of which are annular and parallel to each other. The driving end of the motor 4 drives the two driving chains 54 to rotate synchronously. The rotation direction of the driving chain 54 is perpendicular to the supporting roller 1 and the pressure roller 2, and the rotating driving chain 54 drives the driven chain 55 to rotate. A chain shaft 56 is fixed on the chain link of the driven chain 55, and the chain shaft 56 is slidably connected to the slider 6.

[0054] The beneficial effect of adopting the preferred scheme in the above embodiment is that the connection between the driven chain 55 and the slider 6 is achieved through the chain shaft 56, and in the process of driving the slider 6 to move by the rotation of the driven chain 55, the chain shaft 56 is slidably connected to the slider 6, thereby achieving smooth reciprocating movement of the slider 6, and the slider 6 moves at a uniform speed on the straight section of the driven chain 55, so that the filter cloth is folded and laid evenly.

[0074] Further, one end of the double-headed screw 521 installed on the mounting plate 52 is the end away from the filter cloth, and the other end is spaced apart from the slider 6 to prevent obstruction of the movement of the slider 6. Further, as a parallel solution, the other end of the double-headed screw 521 (the end close to the filter cloth) can be in the shape of a stepped shaft to form a spacing with the slider 6 while installing the bearing.
