Description

Technical Field

[0001] The invention relates to the technical field of filter presses, in particular to an automatic interlocking plate and frame filter press feeding device. Background Art

[0002] The process flow of the plate and frame filter press mainly includes the following steps: 1. Pressing: First, check the entire machine, including whether the filter cloth is folded or damaged, and whether the power supply is properly connected. Then press the "Press" button. The oil pump starts working, and the piston pushes the pressure plate to press. When the filter chamber pressure reaches the designed point, the hydraulic pressure will automatically stop working.

[0003] 2. Feeding: After compaction, start feeding. Turn on the feed pump and slowly open the feed valve. The feed pressure gradually increases to normal pressure.

[0004] 3. Filtration: As the filtration process progresses, the filter cake thickness gradually increases, and the filtration resistance increases. The longer the filtration time, the higher the separation efficiency.

[0005] 4. Pressing and Washing: After the filter cake is formed, it is pressed and washed. The liquid is discharged from the machine through the outlet holes on the plate frame, while the solid particles are trapped in the filter chamber to form a filter cake. Washing further removes interstitial water and capillary water in the sludge, reducing its volume.

[0006] 5. Purging and unloading: Finally, purge and unload the filter cake. After purging, open the unloading valve and unload the filter cake from the filter chamber.

[0007] Purpose Plate and frame filter press Disadvantages: Plate and frame filter presses are generally operated intermittently. When the on-duty personnel fail to replenish the thickening tank in time, mud will accumulate in the advection tank, which will cause damage to the mud suction trolley in the advection tank, reduce the clean water treatment capacity of the advection tank, and affect the industrial clean water preparation capacity. An automatic interlocking plate and frame filter press feeding device is needed to solve this problem. Summary of the Invention

[0008] The object of the present invention is to provide an automatic interlocking plate and frame filter press feeding device to solve the problems raised in the above background technology.

[0009] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an automatic interlocking plate and frame filter press feeding device, comprising a filter press body, a support frame fixedly mounted at the bottom end of the filter press body for supporting the entire filter press body, a filter cake mounted on the filter press body, a filter plate mounted on one side of the filter cake, a pressing plate mounted on the side of the filter plate away from the filter cake, a hydraulic filter press device mounted on the side of the pressing plate away from the filter cake, the filter press body being connected to a concentration tank, and the concentration tank being connected to a horizontal flow tank.

[0010] As a preferred technical solution of the present invention, connecting pipes are connected between the filter press body and the concentration tank, and between the concentration tank and the advection tank, and valves for controlling material discharge are installed on the connecting pipes.

[0011] As a preferred technical solution of the present invention, a high liquid level area and a low liquid level area are respectively installed between the concentration tank and the advection tank, and the high liquid level area and the low liquid level area are connected to the filter press body and the advection tank through the second contactor coil and the first contactor coil respectively.

[0012] As a preferred technical solution of the present invention, reinforcing beams are fixedly installed on both side ends of the filter press body, and a sludge inlet and a filtrate outlet are respectively installed on the filter press body.

[0013] As a preferred technical solution of the present invention, a control panel is fixedly mounted on the filter press body, and the control panel controls the operation of the entire filter press body.

[0014] As a preferred technical solution of the present invention, the model of the filter press body is XMGZ300 / 1500UB.

[0015] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention is an automatic interlocking plate and frame filter press feeding device. The filter press feeding device provided in the device solves the problem that when the liquid level in the thickening tank is too low, the sludge suction trolley cannot replenish the material in time, and when the liquid level is too high, the plate and frame filter press does not unload the material in time. Without replacing the characteristics of the existing equipment, the efficient operation of the three water purification sludge systems as a whole is balanced, ensuring that the plate and frame filter press does not unload the material when the liquid level in the thickening tank is too high, and the sludge suction trolley does not replenish the material when the liquid level in the thickening tank is too low due to the influence of manual operation. The three water purification sludge systems can operate efficiently, and the industrial clean water preparation is stable and supplied. By solving the serious siltation problem in the horizontal flow tank, the stability of the pump station's ability to prepare industrial clean water is ensured, the frequency of fault inspection and maintenance is reduced, and the automation level of the pump station is improved.

[0019] Below, the invention is further described with reference to the accompanying drawings and specific embodiments: Example

[0020] refer to Figures 1 to 2 Embodiment 1 is described, comprising a filter press body 1, a support frame 2 for supporting the entire filter press body 1 being fixedly mounted at the bottom end of the filter press body 1, a filter cake 6 being mounted on the filter press body 1, a filter plate 7 being mounted on one side of the filter cake 6, a compression plate 8 being mounted on the side of the filter plate 7 away from the filter cake 6, a hydraulic filter pressing device 9 being mounted on the side of the compression plate 8 away from the filter cake 6, the filter press body 1 being connected to a thickening tank 14, and the thickening tank 14 being connected to a flat flow tank 11, reinforcing crossbeams 5 being fixedly mounted on both sides of the filter press body 1, a sludge inlet 3 and a filtrate outlet 4 being respectively mounted on the filter press body 1, a control panel 10 being fixedly mounted on the filter press body 1, the control panel 10 controlling the operation of the entire filter press body 1, and the model of the filter press body 1 being XMGZ300 / 1500UB; In this embodiment, the sludge thickening tank 14 automatically feeds the sludge to the plate and frame filter press after the liquid level reaches a certain level, and the plate and frame filter press finally completes the pressing and unloading of the sludge cake. Example

[0021] refer to Figures 2 to 3 Example 2 is described. This embodiment further illustrates Example 1. A connecting pipe 15 is connected between the filter press body 1 and the thickening tank 14 and between the thickening tank 14 and the advection tank 11. A valve for controlling the discharge of materials is installed on the connecting pipe 15. A high liquid level area 12 and a low liquid level area 13 are respectively installed between the thickening tank 14 and the advection tank 11. The high liquid level area 12 and the low liquid level area 13 are connected to the filter press body 1 and the advection tank 11 through a second contactor coil 17 and a first contactor coil 16, respectively. In this embodiment, when the liquid level of the thickening tank 14 is higher than 6 meters, the plate and frame filter press feed pump is controlled to start and the mud suction trolley is stopped, thereby realizing automatic interlocking control of the plate and frame filter press system.

[0022] When the liquid level in the sludge thickening tank 14 is higher than 6 meters, the feed pump of the plate and frame filter press is started and the sludge suction trolley is stopped, thereby realizing automatic interlocking control of the plate and frame filter press system. After the sludge thickening tank 14 reaches a certain liquid level, the sludge thickening tank 14 automatically feeds the plate and frame filter press. Finally, the plate and frame filter press completes the pressing and unloading of the mud cake, thereby eliminating the situation in which the on-duty personnel fail to replenish the thickening tank 14 in time, causing the accumulation of sludge in the advection tank 11 and causing damage to the sludge suction trolley in the advection tank 11, reducing the clean water treatment capacity of the advection tank 11, and affecting the preparation of industrial clean water. The original on-site operation that relied solely on the on-duty personnel running back and forth is changed to automatic control, so that the three water purification sludge systems can operate efficiently and the preparation of industrial clean water can be stably guaranteed.
