Description

Technical Field

[0001] This utility model relates to the technical field of press equipment, specifically a filter bag press. Background Technology

[0002] A press is a commonly used pressing device in production. Currently, presses are needed in food processing, bioprocessing, waste recycling, and other fields to separate solids and liquids from materials, thereby obtaining the desired substances.

[0003] Chinese patent application number CN201210278243.2 discloses a press-type filter bag filter. The filter bag of the above patent has cleaning and pressing dewatering functions. It can clean the filter residue inside the filter bag in a timely manner by reciprocating up and down motion, so that the filter residue on the surface of the filter bag is brushed off, thereby achieving filter bag regeneration and extending filtration time. At the same time, in the later stage of filtration, it can press dewater the high-concentration filter residue. After pressing, the filter residue becomes a solid cake. After pressing, the filter bag returns to its original state and the filter bag and filter cake are separated. Some filter bags are cleaned and regenerated and can continue to filter. The filter bags can be replaced after multiple filtrations and pressings, which reduces the number of filter bag replacements, obtains a solid filter cake, and avoids the difficulty of cleaning fluid filter residue.

[0004] Chinese patent application number CN201110212352.X discloses a pressing dewatering method and apparatus for water-containing materials, solving the problems of current filter press dewatering machines being unable to handle materials with high solid content, long feeding and discharging times, and low dewatering efficiency, thus achieving efficient and low-cost dewatering of materials with high solid content. However, the following problems still exist in practical applications, specifically: 1. In the process of pressing materials, most of the filter residue is left inside the filter bag while the filtrate is discharged to the outside. During the process of unloading the filter residue, the inside of the filter bag needs to be cleaned, which is inconvenient. At the same time, the filter bag needs to be disassembled for cleaning. 2. During the process of unloading the filter residue and cleaning the filter cartridge, the filter residue may not be discharged smoothly, resulting in some filter residue remaining inside the press.

[0005] Therefore, this utility model provides a filter bag press to solve the above problems. Utility Model Content

[0023] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 7 The detailed description of the embodiments will make this clear. All structural details mentioned in the following embodiments are based on the accompanying drawings.

[0024] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0025] This utility model is a filter bag type press, including a square tube frame 1 and a front end box. A hydraulic cylinder 2 is rotatably connected to the upper end of the front end box. A hydraulic cylinder support 3 is fixedly connected to the hydraulic cylinder 2. Several sets of fixed support rods 4 are fixedly connected to the hydraulic cylinder support 3. The several fixed support rods 4 are connected to a barrel body 5. The barrel body 5 slides along the fixed support rods 4. A pressure plate 6 is coaxially slidably connected inside the barrel body 5. The pressure plate 6 is in contact with the inner wall of the barrel body 5. A hydraulic piston 7 is coaxially fixedly connected to the side of the pressure plate 6 near the hydraulic cylinder 2. The hydraulic piston 7 is placed inside the hydraulic cylinder 2. The hydraulic piston 7 and pressure plate 6 are driven by the filling and releasing of oil in the hydraulic cylinder 2. The sliding of the pressure plate 6 realizes the extrusion of the material, thereby realizing the pressing process of the material. A discharge end cap 8 is coaxially connected to the other end of the barrel body 5. Several flexible filter bags 9 are connected between the discharge end cap 8 and the pressure plate 6. A juice discharge flange 10 is provided on the discharge end cap 8. The flexible filter bags 9 and the juice discharge flange 10 are connected. The pressure plate 6 squeezes the material entering the barrel body 5. During the squeezing process, the liquid in the material passes through the flexible filter bags 9 and enters the interior of the flexible filter bags 9, and then enters the juice discharge flange 10 through the flexible filter bags 9, thereby separating the squeezed liquid from the material. A feeding device is connected to the discharge end cap 8. The feeding device conveys the material into the barrel body 5. The feeding device adopts a conventional feeding method. In this embodiment, the material is conveyed into the barrel body 5 through a spiral conveying pipe.

[0026] To ensure the rotation of the barrel 5 during the material pressing process, thereby guaranteeing effective material pressing and ensuring the liquid flows better to the discharge flange 10 after pressing, two rotating brackets 11 are fixedly connected to the end of the square tube frame 1 away from the front end box. Each rotating bracket 11 is rotatably connected to a rotating limit wheel 12. The rotating limit wheel 12 is connected to a drive structure connected to the square tube frame 1, which drives the rotating limit wheel 12. The discharge end cover 8 cooperates with the transfer limit wheel, and the rotation of the rotating limit wheel 12 drives the discharge end cover 8 and the barrel 5 to rotate, thereby ensuring that the barrel 5 is always rotating throughout the entire material pressing process.

[0027] A limiting rod 13 is fixedly connected to the discharge end cover 8, and a sliding limiting sleeve 14 that cooperates with the limiting rod 13 is fixedly connected to the barrel body 5. The sliding limiting sleeve 14 and the barrel body 5 are fixedly connected, so that the barrel body 5 and the discharge end cover 8 can slide relative to each other. The barrel body 5 and the hydraulic cylinder 2 bracket 3 are connected by a telescopic hydraulic rod 15. The extension and retraction of the telescopic hydraulic rod 15 drives the barrel body 5 to slide, and the extension and retraction of the telescopic hydraulic rod 15 drives the relative sliding between the barrel body 5 and the discharge end cover 8, thereby meeting the needs of feeding and discharging.

[0028] To achieve cleaning of the inner wall of the barrel 5 and ensure its cleanliness after use, this embodiment provides a structure for cleaning the inner wall of the barrel 5. Specifically, several spray nozzles 16 are fixedly connected to the pressure plate 6 near the discharge end cover 8. The pressure plate 6 has a hollow structure, and several liquid guide pipes 17 connected to the spray nozzles 16 are connected inside the pressure plate 6. Water is supplied to the spray nozzles 16 through the liquid guide pipes 17, and water is sprayed into the barrel 5 through the spray nozzles 16, thereby cleaning the inner wall of the barrel 5. The liquid guide pipes 17 are connected in parallel to a water supply device placed inside the front end box through a flexible conduit. Liquid is supplied to the pressure plate 6 through the flexible conduit by an external water supply device. At the same time, the flexible conduit facilitates the sliding of the pressure plate 6, thereby ensuring smooth liquid supply to the pressure plate 6.

[0029] A base frame 18 is placed at the lower end of the square tube frame 1. The end of the square tube frame 1 away from the front end box is rotatably connected to the base frame 18. An adjusting push rod 19 is rotatably connected to the lower end of the square tube frame 1. A slide 20 is rotatably connected to the other end of the adjusting push rod 19. The slide 20 is slidably connected to the base frame 18. An adjusting screw 21 is rotatably connected inside the base frame 18 and threadedly connected to the slide 20. The adjusting screw 21 is connected to a drive motor connected to the base frame 18. When the drive motor rotates, it drives the adjusting screw 21 to rotate. The rotation of the adjusting screw 21 drives the slide 20 to slide. The side wall of the slide 20 fits against the base frame 18 to limit the movement of the slide 20. During the sliding process of the slide 20, the adjusting push rod 19 drives the square tube frame 1 to rotate around the base frame 18, thereby enabling the material in the barrel 5 to slide down quickly and smoothly during the unloading and washing process.

[0030] The base frame 18 is internally connected to a storage trough 22, which is used to collect discharged materials. The storage trough 22 has an open top, which facilitates the guidance and collection of materials falling from the barrel 5. The lower end of the storage trough 22 is connected to an external spiral conveyor, which transports the materials entering the storage trough 22 to the outside.

[0031] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
