Description

Technical Field

[0001] This utility model relates to the field of filter press frame technology, specifically a filter press moving frame device. Background Technology

[0002] As a key piece of equipment in the field of solid-liquid separation, the filter press's mobile frame plays a crucial role in supporting the filter plates, connecting various functional pipelines, and ensuring the stable movement of the filter plates, directly affecting the filter press's operating efficiency and service life. In the existing design of the filter press's mobile frame, to achieve functions such as water inlet, water outlet, filter cloth cleaning, and drying, the interfaces of related pipelines generally adopt an externally connected layout. That is, through additional external supports or pipeline bundles, the water inlet, water outlet, water cleaning, and air drying pipelines are centrally arranged on the outside of the frame.

[0003] This external row design method has certain drawbacks: On the one hand, the pipelines lack unified and orderly integrated support, and various pipelines are intertwined and arranged in a messy manner, which not only occupies extra space around the equipment, but also makes them prone to collisions and scratches with other components or operating tools in the external environment. On the other hand, exposed pipes and interfaces lack effective protection. During equipment operation vibration, daily operation and maintenance, or material transfer in the workshop, they are easily deformed, loosened, or even damaged by external impacts and friction, which can lead to water and air leaks. This not only increases the frequency and cost of equipment maintenance but also interrupts the filter press operation process, reduces overall production efficiency, and poses a safety hazard to on-site operations. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a mobile frame device for filter presses.

[0005] To achieve the above objectives, this utility model provides the following technical solution: The filter press moving frame device includes: a support frame, two supports symmetrically arranged left and right, vertical plates on the front and rear sides of the support frame, the vertical plates being fixedly connected to the two side supports by bolts, a supporting horizontal plate on the vertical plate, a feed pipe at the center of the top of the support frame, L-shaped plates on the left and right sides of the feed pipe, water pipes and air pipes on the front and rear sides of the upper part of the support frame respectively, and water inlet pipes and water outlet pipes on the front and rear sides of the lower part of the support frame respectively. The water pipes, air pipes, water inlet pipes and water outlet pipes are all connected to the filter plates of the filter press. A guide rail is provided on the top of the vertical plate, and a locking block is provided on the inner wall of the vertical plate. The guide rail cooperates with the guide block on the filter plate of the filter press to enable the filter plate to move on the vertical plate, and the feed pipe is used to deliver slurry to the filter chamber; The inlet pipe is used to deliver squeezed water to the expansion diaphragm of the filter plate, so that the expansion diaphragm expands and squeezes the filter cake, squeezing out the residual water, and the diaphragm water channel is completely isolated from the slurry channel. The outlet pipe is used to compress the solids to form a filter cake, and the filtered liquid is discharged from the outlet pipe.

[0006] Preferably, the L-shaped plate is used to fix the communication connector block to the L-shaped plate by bolts; The locking block is used to lock the filter plate when it is pressed to a certain position.

[0007] Preferably, the horizontal support plate is used to install the cable drag chain, and the vertical plate side wall is bolted with a fixed bracket for connecting the hydraulic cylinder. The water pipe is used to spray water onto the filter cloth for cleaning, and the air pipe is used to blow air onto the filter cloth for drying.

[0008] Compared with the prior art, the present invention provides a moving frame device for a filter press, which has the following advantages: By integrating all functional pipelines directly into the upper and lower parts of the support body, the pipelines are distributed in an orderly manner along the support, avoiding the situation of pipelines crossing or being exposed. The overall structure of the equipment is more compact and regular, effectively saving the space around the equipment, while reducing the direct contact between pipelines and the external environment, and reducing the risk of damage caused by collisions and scratches.

[0009] The connection interfaces of each pipe are more stable and less prone to loosening due to vibration or external force, effectively reducing the probability of malfunctions such as water leakage and air leakage; at the same time, it avoids functional delays or failures caused by messy pipes, further ensuring the continuous and stable operation of the filter press and improving the solid-liquid separation efficiency.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Reference Figures 1-4 As shown, a filter press moving frame device of this embodiment includes two symmetrically arranged supports 1. Vertical plates 201 are mounted on the front and rear sides of each support 1. The vertical plates 201 are fixedly connected to the supports 1 on both sides by bolts. This connection method ensures the stability of the connection between the vertical plates 201 and the supports 1, and facilitates subsequent disassembly and maintenance. A supporting horizontal plate 202 is fixed to the outer side of the vertical plate 201. The supporting horizontal plate 202 is used to install cable drag chains. A fixing bracket is installed on the inner wall of the vertical plate 201 by bolts to connect a hydraulic cylinder, providing power support for the pressing action of the filter plates.

[0014] A feed pipe 101 is installed through the center of the top of the support frame 1. L-shaped plates 3 are symmetrically arranged on the left and right sides of the feed pipe 101. Bolt holes are reserved on the L-shaped plates 3 for fixing the communication connector block to the plate body with bolts to ensure stable connection of equipment communication and power supply. Water pipes 401 and air pipes 402 are respectively installed on the front and rear sides of the upper part of the support frame 1, and water inlet pipes 103 and water outlet pipes 102 are respectively installed on the front and rear sides of the lower part. The water pipes 401, air pipes 402, water inlet pipes 103 and water outlet pipes 102 are all connected to the filter plates of the filter press. The water pipes 401 are used to spray water onto the filter cloth to clean residual filter residue, the air pipes 402 are used to blow air onto the cleaned filter cloth to dry it, the water inlet pipes 103 are specifically used to deliver squeeze water to the expansion diaphragm of the filter plate, and the water outlet pipes 102 receive the filtered water generated by the filter cake after squeezing and discharge it outward.

[0015] In addition, a guide rail is provided at the top of the vertical plate 201. The guide rail cooperates with the guide block of the filter plate of the filter press. The filter plate moves left and right along the vertical plate 201 to ensure the movement trajectory of the filter plate. A locking block is also fixed on the inner wall of the vertical plate 201. When the filter plate is squeezed to the preset position by the hydraulic cylinder, the locking block can lock the position of the filter plate to prevent the filter plate from shifting and affecting the filtration effect. At the same time, the feed pipe 101 can stably deliver slurry to the filter chamber to ensure continuous filtration operation.

[0016] In some examples, a flow regulating valve is connected in series on the air duct 402. The operator can control the air pressure and flow by adjusting the flow regulating valve, and flexibly adjust the drying intensity according to the filter cloth material and cleaning needs, so as to avoid damaging the filter cloth due to excessive air pressure or incomplete drying due to insufficient air pressure.
