Description

Technical Field

[0001] This utility model belongs to the technical field of solid-liquid separation equipment, specifically, it relates to a multi-layer pressing filter press device. Background Technology

[0002] Solid-liquid separation is a crucial operation in many industrial production processes and wastewater treatment, and multi-layer press filter presses are key equipment for achieving this goal.

[0003] In traditional filter press technology, early filter press equipment was mostly simple gravity or low-pressure filter press devices. Gravity filter press mainly relies on the liquid's own gravity to pass through the filter medium to achieve solid-liquid separation, and is only suitable for materials with larger solid particles and faster settling speeds. Early low-pressure filter press devices accelerated the solid-liquid separation speed by applying a certain pressure, but due to limited pressure, the moisture content of the filter cake remained high, significantly increasing subsequent processing costs.

[0004] With technological advancements, filter presses apply pressure to materials using mechanical power, thereby improving solid-liquid separation efficiency and filter cake quality to some extent. However, in multi-layer pressing processes, the filtrate collection method is not perfect. Due to the lack of a reasonable filtrate guiding and collection structure, the filtrate easily splashes into the surrounding environment, causing not only material loss and increased production costs but also pollution of the working environment, affecting the hygiene and safety of production.

[0005] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0028] This utility model provides a multi-layer pressing filter device. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit the scope of protection of this utility model.

[0029] Reference Figure 1-4A multi-layer press-type filter press device includes a frame 1, a collection assembly 4 for collecting liquid, and a filter press assembly 5 for pressing and filtering the liquid. A pressing assembly 2 is mounted on the frame 1, located on the right side of the frame 1. A steel plate 3 is fixedly connected to the side of the frame 1 away from the pressing assembly 2, located on the left side of the frame 1. An inlet pipe 7 is fixedly connected to the center of the steel plate 3. A flange 8 is fixedly connected to the end of the inlet pipe 7 away from the steel plate 3. A pipe for transmitting liquid is connected to the inlet pipe 7 via the flange 8. A pressure plate 9 is installed inside the frame 1, and the pressure plate 9 is connected to the pressing assembly... The filter press assembly 5 is connected to the frame 1 and is located between the pressure plate 9 and the steel plate 3. The collection assembly 4 is equipped with a positioning component 6, which is located on the four legs of the frame 1. The collection assembly 4 is mounted on the frame 1 via the positioning component 6. After the liquid is transmitted to the inside of the filter press assembly 5 through the inlet pipe 7 and the flange 8, the pushing component 2 pushes the pressure plate 9 to move. The filter press assembly 5 located between the steel plate 3 and the pressure plate 9 is compressed. The liquid produced by the filter press drips vertically into the inside of the collection assembly 4, thereby minimizing the possibility of the filtrate splashing into the surrounding environment and reducing material loss.

[0030] Reference Figure 1 and Figure 3 The collection assembly 4 includes a collection chamber 41. The width of the top opening of the collection chamber 41 is greater than the width of the filter press assembly 5. The cross-sectional area of ​​the collection chamber 41 gradually increases from bottom to top. A drain pipe 42 is fixedly connected to the outer wall of the collection chamber 41. The drain pipe 42 is located on the left side of the collection chamber 41. A valve 43 is fixedly installed on the drain pipe 42. An inclined plate 44 is fixedly connected to the inner bottom wall of the collection chamber 41. The inclined plate 44 is set at an inclination. After the liquid drips into the inside of the collection chamber 41, it flows at an inclination through the inclined plate 44. The drain pipe 42 and the valve 43 facilitate the discharge of the liquid.

[0031] Reference Figure 1-2 The filter press assembly 5 includes several filter plates 51. A steel plate 3 is fixedly connected to one of the filter plates 51, and a pressure plate 9 is fixedly connected to the filter plate 51 at the other end. A filter cloth 52 is fixed between two adjacent filter plates 51. A slider 53 is fixedly connected to the outer wall of each of the filter plates 51. Each filter plate 51 is provided with two symmetrical sliders 53. The sliders 53 are in contact with the frame 1. During the movement of the filter plates 51, the sliders 53 on the frame 1 move accordingly, so that the filter plates 51 are stacked together.

[0032] Reference Figure 1-2 A circular hole 54 is provided at the center of several filter plates 51, and filter holes 55 are provided on several filter plates 51. The filter holes 55 are located above the circular hole 54. Liquid flows and is transported through the circular hole 54. When the liquid level exceeds the circular hole 54, some liquid is transported through the filter hole 55, and some liquid is separated into solid and liquid, which facilitates the transport of liquid inside the filter press assembly 5.

[0033] Reference Figure 4 Rollers 10 are attached to the frame 1 and fixed to the pressure plate 9. The rollers 10 cause the pressure plate 9 to move horizontally on the frame 1.

[0034] Reference Figure 1 and Figure 3 The positioning component 6 includes a triangular steel 61 fixedly connected to the frame 1. The triangular steel 61 has a threaded hole 64. A horizontal plate 62 is fixedly connected to the outer wall of the collection bin 41. A bolt 63 is threadedly connected to the horizontal plate 62. The bolt 63 is adapted to the threaded hole 64. The horizontal plate 62 is detachably installed on the triangular steel 61 by the bolt 63. After the collection bin 41 moves on the triangular steel 61, the bolt 63 thread passes through the horizontal plate 62 and is connected to the triangular steel 61 through the threaded hole 64, so that the collection bin 41 can be detachably installed on the positioning component 6.

[0035] Reference Figure 4 The pressing assembly 2 includes a hydraulic rod 21 fixed on the frame 1. A pressure block 22 is fixedly connected to the end of the piston rod of the hydraulic rod 21. The piston rod of the pressure block 22 passes through the interior of the frame 1. A reinforcing plate 23 is fixedly connected to the pressure block 22. The reinforcing plate 23 is fixed inside the pressure plate 9. After the hydraulic rod 21 is operated, the pressure block 22 pushes the reinforcing plate 23 to move, and the pressure plate 9 moves accordingly after being subjected to external force.

[0036] Working principle: First, one end of the infusion tube is connected to the inlet pipe 7 through the flange 8. The liquid is transmitted to the inside of the filter press assembly 5 through the inlet pipe 7. The liquid is evenly distributed inside the filter plate 51 through the round hole 54. When the liquid height between two adjacent filter plates 51 is too high, the liquid flows to each other through the filter hole 55. The hydraulic rod 21 runs, the pressure block 22 pushes the reinforcing plate 23 to move, the pressure plate 9 moves towards the steel plate 3, and the roller 10 makes the pressure plate 9 move horizontally. After the filter press assembly 5 located between the steel plate 3 and the pressure plate 9 is under pressure, the liquid is filtered through the filter cloth 52 and drips into the inside of the collection chamber 41. The inclined plate 44 makes the liquid inside the collection chamber 41 flow at an angle towards the drain pipe 42, and then it is discharged through the drain pipe 42 and the valve 43. When it is necessary to clean the inside of the collection chamber 41, the bolt 63 is rotated upward to separate from the triangular steel 61 and the horizontal plate 62. Then the collection chamber 41 can be removed, which facilitates the disassembly and cleaning of the collection chamber 41.
