Description

Technical Field

[0001] This utility model relates to the field of filter press technology, and in particular to a filter press feeding structure. Background Technology

[0002] A filter press is a mechanical device used for solid-liquid separation, widely used in industries such as chemical, pharmaceutical, food, and environmental protection. Driven by pressure, it traps solid particles in a suspension on filter cloth or plates, while the liquid passes through the filter medium and is discharged, thus achieving efficient separation. A filter press mainly consists of filter plates, filter frames, a pressing device, and filter media. Operation methods include manual, automatic, and hydraulic. Its characteristics include large throughput, good filtration effect, and strong adaptability, capable of handling high-concentration or viscous materials. Based on different structures, it can be divided into plate and frame filter presses, chamber filter presses, and diaphragm filter presses.

[0003] Because the slurry suspension contains many impurities, such as large stones or garbage, these impurities can cause blockages in the filter press's feed pipes after entering the press. Furthermore, some clumps of slurry can clog the inlets of the filter plates, necessitating shutdown for maintenance and manual cleaning of the blocked material, thus affecting work efficiency. Therefore, further improvements are needed. To address this, we have proposed a new filter press feed structure. Utility Model Content

Detailed Implementation

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1-3 As shown, a filter press feeding structure is disclosed, including a base plate 1. Multiple support rods 2 are fixed on the upper surface of the base plate 1. The tops of the multiple support rods 2 are fixedly connected to a material trough 3. A material inlet is opened at the top of the material trough 3, and a cleaning component 4 is installed inside the material inlet. The bottom of the material trough 3 is cone-shaped, and a square tube 5 is fixedly connected to the bottom of the material trough 3. A chopping component 6 is arranged in the middle of the material trough 3 and the square tube 5. A pump body 7 is arranged on the upper surface of the base plate 1 to extract the material inside the square tube 5. A side opening 51 is opened on the side of the square tube 5 near the pump body 7. A liquid inlet 71 is fixedly connected to the liquid inlet of the pump body 7. A detachable anti-clogging component 8 is arranged between the liquid inlet 71 and the side opening 51.

[0022] The impurity removal component 4 includes a filter frame 41 located inside the feed inlet, and a coarse filter screen 42 is fixed to the bottom of the filter frame 41. The top of the filter frame 41 is fixed to the inside of the feed inlet by bolts.

[0023] In this embodiment, the coarse filter screen 42 can ensure that agglomerated materials can pass through, but larger garbage cannot pass through, thereby intercepting the garbage in the filter frame 41. The filter frame 41 is detachable, making it easy to remove the filter frame 41 from the feed inlet and clean the garbage inside the filter frame 41.

[0024] The chopping assembly 6 includes a motor 61 fixed to the top of the feed trough 3. A vertical shaft 62 is fixed to the bottom output end of the motor 61. Multiple blades 63 are fixed to the bottom surface of the vertical shaft 62. The blades 63 are located inside the square tube 5.

[0025] After being filtered by the coarse filter screen 42, the mud material enters the trough 3 and the square tube 5. At this time, the motor 61 is started to drive the vertical shaft 62 and the blade 63 to rotate, and the blade 63 is used to chop and disperse the mud material.

[0026] The anti-clogging component 8 includes a sleeve 81 that is slidably connected to the liquid extraction tube 71 and a side cover 82 that fits into the side opening 51. A fine filter screen 83 is provided inside the side cover 82, and the fine filter screen 83 covers the side opening 51.

[0027] In this embodiment, the outlet of the pump body 7 is connected to the filter press. When the pump body 7 is used to extract the mud from the inside of the square tube 5, the mud will be filtered by the fine filter screen 83 to prevent the lumps of material in the mud from entering the filter press. The pump body 7 is a mud pump.

[0028] The inner wall of the sleeve 81 is provided with multiple annular grooves, and a sealing ring 84 is fixed inside each annular groove. The sealing ring 84 is in contact with the surface of the liquid extraction tube 71.

[0029] An L-shaped plate 9 is fixed on the outer wall of the square tube 5 and above the side opening 51. The L-shaped plate 9 is connected to a screw rod 10 through the side away from the square tube 5 by a threaded rotation. The end of the screw rod 10 close to the square tube 5 is in contact with the surface of the side cover 82.

[0030] When the fine filter screen 83 needs to be removed for cleaning or replacement, screw 10 is turned to separate it from the side cover 82. After the side cover 82 is no longer squeezed by screw 10, the sleeve 81 can slide along the surface of the liquid extraction tube 71 and separate from the square tube 5. At this time, the fine filter screen 83 inside the side cover 82 can be taken out for replacement. The sealing ring 84 ensures the sealing between the sleeve 81 and the liquid extraction tube 71.

[0031] Working principle: First, the mud material is poured into the filter frame 41 and filtered and separated by the coarse filter screen 42. After filtration, the mud material enters the material tank 3 and the square tube 5. At this time, the motor 61 is started to drive the blade 63 to rotate, and the blade 63 is used to chop and disperse the mud material. Then, the pump body 7 is started to extract the mud material in the square tube 5. During this process, the fine filter screen 83 is used to filter the mud material, so that the lumpy material in the mud material is intercepted. After the mud is extracted, it enters the filter press for filtration.

[0032] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
