DETAILED DESCRIPTION OF THE EMBODIMENTS
[0013] The present utility model will now be further described in detail in conjunction with the drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, and therefore only showing the components related to the present utility model.
[0014] As Figure 1As shown in the figure, an installation mechanism for a filter cloth of a plate filter press of the present utility model. The plate filter press includes a pressure roller 1, and the filter cloth 2 is installed on the pressure roller 1 through the filter cloth installation mechanism. The filter cloth 2 is wound around the surface of the pressure roller 1. The filter cloth installation mechanism includes two sets of installation components, which are respectively located at both ends of the pressure roller 1. Each set of installation components includes a circular shaft 3 and a fixing component. The outer diameter of the circular shaft 3 is the same as the outer diameter of the pressure roller 1, and the circular shaft 3 is fixedly connected to the end of the pressure roller 1. At least two sets of fixing components are arranged on each circular shaft 3. Each set of fixing components includes a limiting rod 4 and a fixing unit 5. One end of the limiting rod 4 is fixed on the circular shaft 3, and the other end of the limiting rod 4 extends radially along the circular shaft 3. The vertical cross-section of the limiting rod 4 is a trapezoid with a larger upper part and a smaller lower part. The end far from the circular shaft 3 is the upper end, and the end connected to the circular shaft 3 is the lower end. As Figure 2 shown, the fixing unit 5 includes a fixing part 5-1 and a pressing part 5-2. The top surface of the fixing part 5-1 is provided with a limiting groove 5-11, an installation hole 5-12 and a plurality of thorn grooves 5-13. The bottom surface of the pressing part 5-2 is provided with a through hole 5-21, a limiting post 5-22 and a plurality of positioning thorns 5-23. The pressing part 5-2 is covered on the fixing part 5-1. The positioning thorns 5-23 are inserted into the thorn grooves 5-13 one by one. The limiting post 5-22 is inserted into the limiting groove 5-11 to cooperate with the limiting groove 5-11. The installation hole 5-12 and the through hole 5-21 are correspondingly communicated to form a sleeve hole. The limiting rod 4 is inserted into the sleeve hole, and the larger end of the limiting rod 4 passes through the sleeve hole. The size of the sleeve hole matches the size of the smaller end of the limiting rod 4. The fixing part 5-1 and the pressing part 5-2 are fixed by bolts 6 and / or screws 7. The fixing unit 5 is pressed on the edge of the filter cloth 2. The edge of the filter cloth 2 is located between the fixing part 5-1 and the pressing part 5-2 and is fixed by the positioning thorns 5-23 and the thorn grooves 5-13.
[0015] Two sets of fixing components are arranged on each circular shaft 3, and the two sets of fixing components are symmetrically arranged with respect to the central axis of the pressure roller 1.
[0016] To facilitate the installation of the fixing unit 5 and the limiting rod 4, the limiting rod 4 is fixedly connected to the circular shaft 3 by surface plugging. After plugging, the structure can be fixed by setting fixing bolts or the like. The vertical cross-section of the limiting rod 4 is a right trapezoid. After the filter cloth 2 is installed, as Figure 3 shown, the vertical cross-section of the limiting rod 4 is a right trapezoid, and the hypotenuse of the right trapezoid faces away from the filter cloth 2. The limiting rod 4 can be disassembled first, and then the fixing unit 5 is installed. The size of the sleeve hole matches the size of the smaller part at the lower end of the limiting rod 4. In this way, the outer diameter of the limiting rod 4 becomes larger in the upward direction, and the fixing unit 5 can be locked to prevent the fixing unit 5 from detaching from the limiting rod 4 due to vibration.
[0017] The utility model realizes the extension of the pressing roller 1 to both ends by arranging the round shaft 3, integrates the filter cloth installation mechanism with the pressing roller 1 of the filter press, ensures the synchronous rotation of the filter cloth installation mechanism and the pressing roller 1, prevents the speed difference between the filter cloth installation mechanism and the pressing roller 1, and the filter cloth 2 will not tilt or wrinkle, ensuring the filtering effect and prolonging the service life of the filter cloth 2. At the same time, through the cooperation of the fixing unit 5 and the limiting rod 4, the filter cloth 2 can be conveniently installed and disassembled, improving the efficiency of replacing the filter cloth 2. Since the filter cloth 2 will vibrate more or less when rotating with the pressing roller 1, the vertical section of the limiting rod 4 in the fixing unit 5 is trapezoidal with the upper part larger than the lower part, which can effectively prevent the fixing unit 5 from detaching from the limiting rod 4 and ensure the fixing effect of the filter cloth 2.
[0018] When installing the filter cloth 2, the filter cloth 2 is attached to the surface of the pressing roller 1, and the two side edges of the filter cloth 2 respectively extend to the installation components on both sides of the pressing roller 1. The fixing unit 5 is removed from the limiting rod 4, that is, the limiting rod 4 is taken out of the sleeve hole, the bolt 6 and / or the screw 7 are opened, and the fixing part 5-1 and the pressing part 5-2 of the fixing unit 5 can be separated from each other. The edge of the filter cloth 2 is placed on the top surface of the fixing part 5-1, and then the pressing part 5-2 is covered on the filter cloth 2 corresponding to the top surface of the fixing part 5-1. At this time, the positioning thorn 5-23 is inserted into the filter cloth 2 to fix the filter cloth 2. At the same time, the limiting column 5-22 and the limiting groove 5-11 realize the positioning of the fixing part 5-1 and the pressing part 5-2, which is more convenient for the cooperative installation of the fixing part 5-1 and the pressing part 5-2. Then the bolt 6 and / or the screw 7 are inserted into the fixing part 5-1 and the pressing part 5-2 to fix the two. After the filter cloth 2 is installed on the fixing unit 5, the sleeve hole of the fixing unit 5 is sleeved on the corresponding limiting rod 4. When the filter cloth 2 is installed at each fixing unit 5 and limiting rod 4, the installation of the filter cloth 2 is completed.
