Description

Technical Field

[0001] This application relates to the field of filter press technology, and in particular to an automated sludge storage hopper for a filter press. Background Technology

[0002] In the industrial production field, the chamber filter press is a highly efficient solid-liquid separation device. After the chamber filter press completes the solid-liquid separation operation, it will form a filter cake with a certain moisture content. These filter cakes usually need to be collected by the sludge hopper for further processing.

[0003] The filter cake formed after solid-liquid separation of industrial wastewater sludge contains a certain proportion of moisture, making it relatively soft and sticky. Therefore, the collected filter cake often needs to be crushed and dried first to allow the moisture in the cake to evaporate more quickly and completely. After drying, the filter cake is then transported to a designated location for landfill or incineration.

[0004] However, existing sludge storage hoppers have a relatively simple function, mainly serving as a simple collection container. They lack a mechanism for effectively crushing and guiding the collected filter cake. The sludge storage hopper cannot directly crush the filter cake inside; it usually requires an additional specialized crushing device to transfer the filter cake from the sludge storage hopper to this device for crushing. This transfer process increases operational steps and labor costs, and may also lead to problems such as spillage and leakage of the filter cake during transfer. In addition, when the filter cake falls from the chamber filter press into the sludge storage hopper, due to the lack of a dedicated guiding structure, the filter cake may accumulate unevenly in the sludge storage hopper, with some areas being too thick and others relatively empty. This not only affects the effective storage capacity of the sludge storage hopper, but also brings difficulties to the subsequent crushing work.

[0005] To address the aforementioned issues, an automated sludge storage hopper for filter presses is now designed. Utility Model Content

[0006] This application provides an automated sludge storage hopper for a filter press to address the problem that existing sludge storage hoppers in the related art have a relatively simple function, mainly serving as a simple collection container, lacking a mechanism for effectively crushing and guiding the collected filter cake, and are inconvenient to use.

[0007] In a first aspect, an automated sludge storage hopper for a filter press is provided, comprising: The frame is equipped with a box-type press, a sludge storage hopper is arranged below the frame, and a slag discharge hopper is arranged on the frame. The box-type press, slag discharge hopper and sludge storage hopper are arranged in sequence from top to bottom. The sludge storage hopper is equipped with a guide plate with a notch. A crusher is installed inside the notch. The guide plate is used to guide the filter cake into the crusher, which crushes the filter cake. The sludge storage hopper is equipped with a conveyor located below the guide plate. A discharge valve is connected to the bottom of the sludge storage hopper. The conveyor is used to guide the crushed filter cake inside the sludge storage hopper to the discharge valve for discharge.

[0008] In some embodiments, a guardrail is provided on the outer perimeter of the frame, and a pedestrian ladder is arranged on one side of the frame.

[0009] In some embodiments, the slag discharge hopper is a cone shape that is wider at the top and narrower at the bottom, and the interior of the slag discharge hopper has a cavity with both the top and bottom ends being open.

[0010] In some embodiments, the guide plate includes two inclined plates disposed opposite each other inside the sludge hopper, a horizontal plate is disposed between the two inclined plates, and a notch is formed between the two inclined plates, the horizontal plate and the sludge hopper; The inclined plate is inclined downward at the end near the horizontal plate, and the horizontal plate is inclined downward at the end near the notch; The guide plate also includes breakers that are staggered on the inclined plate and the horizontal plate.

[0011] In some embodiments, the crusher includes a mounting frame disposed inside the notch, a housing disposed on one side of the mud storage hopper, and a reducer and a drive motor disposed on one side of the housing; The mounting frame has two crushing rollers that rotate relative to each other, and the outer shell has two rotating shafts that rotate relative to each other. One end of each rotating shaft is connected to the corresponding crushing roller. Both rotating shafts are equipped with gears that mesh with each other. The output shaft of the drive motor is connected to the input shaft of the reducer, and the output shaft of the reducer is connected to the other end of either rotating shaft.

[0012] In some embodiments, the sludge storage hopper is a conical hopper that is wider at the top and narrower at the bottom, with an open top, and the interior of the sludge storage hopper has a chamber for storing filter cake residue.

[0013] In some embodiments, the conveying component includes a conveying channel disposed below the interior of the sludge storage hopper. The conveying channel is semi-circular and has a through hole that communicates with the discharge valve. A spiral conveying rod is rotatably installed inside the conveying channel. A second drive motor and a second reducer are installed on one side of the sludge storage hopper. The output shaft of the second drive motor is connected to the input shaft of the second reducer, and the output shaft of the second reducer is connected to the end of the spiral conveying rod away from the through hole.

[0014] This application provides an automated sludge storage hopper for a filter press. By using a discharge hopper, a sludge storage hopper, a guide plate, a crusher, and a conveying component in combination, the functions of guiding, crushing, and conveying the filter cake can be integrated. This avoids the cumbersome process of requiring multiple independent devices and frequent transfer of filter cake in traditional processing methods. After the filter cake is discharged from the chamber press, it directly passes through the guiding, crushing, and conveying steps in sequence, which greatly shortens the processing time and improves the overall processing efficiency.

[0015] While the chamber press continuously produces filter cake, the guide plate, crusher, and conveyor in the sludge storage hopper can work continuously to process the newly generated filter cake in a timely manner, ensuring the continuity and stability of the production process, reducing equipment downtime, and further improving processing efficiency.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] This application provides an automated sludge storage hopper for a filter press, which solves the problem that existing sludge storage hoppers in the related art have relatively simple functions, mainly serving as a simple collection container, lacking a mechanism for effectively crushing and guiding the collected filter cake, and are inconvenient to use.

[0021] Please see Figures 1-3 An automated sludge storage hopper for a filter press includes: a frame 1 on which a chamber press 2 is mounted; a sludge storage hopper 3 is arranged below the frame 1; a slag discharge hopper 4 is mounted on the frame 1; the chamber press 2, slag discharge hopper 4, and sludge storage hopper 3 are arranged sequentially from top to bottom; a guide plate 5 is provided inside the sludge storage hopper 3; the guide plate 5 has a notch 51; a crusher 6 is arranged inside the notch 51; the guide plate 5 is used to guide the filter cake into the crusher 6; the crusher 6 crushes the filter cake; a conveying component 7 is provided inside the sludge storage hopper 3 below the guide plate 5; a discharge valve 8 is connected to the bottom of the sludge storage hopper 3; the conveying component 7 is used to guide the crushed filter cake inside the sludge storage hopper 3 to the discharge valve 8 for discharge.

[0022] After the chamber press 2 completes the solid-liquid separation, the filter cake produced falls into the slag discharge hopper 4. Guided by the slag discharge hopper 4, the filter cake enters the sludge storage hopper 3.

[0023] The sludge storage hopper 3 is equipped with a guide plate 5, which guides the filter cake falling into the sludge storage hopper 3 to the crusher 6. The crusher 6 crushes the filter cake, breaking larger pieces into smaller particles for subsequent processing. The crushed filter cake falls into the working range of the conveyor 7 under gravity. After the conveyor 7 is started, it conveys the crushed filter cake towards the discharge valve 8 connected to the bottom of the sludge storage hopper 3. When the filter cake needs to be discharged, the discharge valve 8 is opened, and the conveyor 7 discharges the filter cake from the sludge storage hopper 3 through the discharge valve 8, completing the entire filter cake processing process.

[0024] By using the slag discharge hopper 4, sludge storage hopper 3, guide plate 5, crusher 6 and conveyor 7 together, the functions of guiding, crushing and conveying filter cake can be integrated, avoiding the cumbersome process of multiple independent equipment and frequent transfer of filter cake in the traditional treatment method. After the filter cake is discharged from the chamber press 2, it directly goes through the guiding, crushing and conveying steps in sequence, which greatly shortens the processing time and improves the overall processing efficiency.

[0025] While the chamber press 2 continuously produces filter cake, the guide plate 5, crusher 6 and conveyor 7 in the sludge storage hopper 3 can work continuously to process the newly generated filter cake in a timely manner, ensuring the continuity and stability of the production process, reducing equipment downtime, and further improving processing efficiency.

[0026] The guide plate 5 accurately guides the filter cake into the crusher 6, ensuring that all filter cakes are fully crushed. The crushed filter cake particles are uniform and fine, with an increased specific surface area, which is beneficial for subsequent drying, landfilling or incineration.

[0027] The conveyor 7 can uniformly and stably transport the crushed filter cake to the discharge valve 8 for discharge, avoiding the problem of uneven accumulation or blockage of the filter cake in the mud storage hopper 3, ensuring smooth discharge, and enabling the filter cake to be discharged according to the predetermined flow rate and speed, which is conducive to the stable operation of subsequent processing links and improves the quality of the entire processing system.

[0028] like Figure 1 and Figure 2 As shown, in one embodiment, a guardrail 11 is provided on the outer perimeter above the frame 1, and a pedestrian ladder 12 is arranged on one side of the frame 1.

[0029] The guardrail 11 is installed on the outer perimeter above the frame 1, forming a semi-enclosed protective structure around the top of the frame. When operators perform equipment inspection, maintenance or other operations above the frame, the guardrail can form a safety boundary to prevent operators from falling from the edge of the frame due to accidental slips, collisions or other reasons, thus ensuring the personal safety of operators when working at heights.

[0030] A pedestrian ladder 12 is located on one side of the frame 1, providing operators with a safe passage from the ground to the top of the frame.

[0031] like Figure 1 and Figure 2 As shown, further, the slag discharge hopper 4 in this embodiment is a cone shape that is wider at the top and narrower at the bottom. The slag discharge hopper 4 has a cavity inside, and both its upper and lower ends are open.

[0032] The tapered structure of the slag discharge hopper 4, which is wider at the top and narrower at the bottom, results in a large opening area at the top, which can fully receive the filter cake discharged from the upper chamber press 2. The tapered side has a certain angle of inclination, and the filter cake will slide down the tapered side wall under its own gravity. As the filter cake continues to slide down, the opening at the bottom of the slag discharge hopper gradually narrows, which plays a role in gathering and guiding the filter cake, and finally guides the filter cake accurately into the sludge storage hopper 3 below.

[0033] like Figure 3 and Figure 4 As shown, in one embodiment, the guide plate 5 includes two inclined plates 52 disposed opposite to each other inside the sludge hopper 3, and a horizontal plate 53 is disposed between the two inclined plates 52. The two inclined plates 52, the horizontal plate 53 and the sludge hopper 3 enclose a notch 51. The end of the inclined plate 52 near the horizontal plate 53 is inclined downward, and the end of the horizontal plate 53 near the notch 51 is inclined downward. The guide plate 5 also includes crushing rods 54 that are staggered on the inclined plates 52 and the horizontal plate 53.

[0034] The two inclined plates 52 provide a clear path for the filter cake to slide down using their inclined surfaces. When the filter cake falls from the slag discharge hopper 4 into the sludge storage hopper 3, it will first come into contact with the inclined plates 52. The inclined plates 52 have an inclined angle, and the filter cake will slide down along the inclined plates 52 under its own gravity.

[0035] The inclined plate 52 is tilted downward at the end near the horizontal plate 53, so that the filter cake can smoothly transition from the inclined plate 52 to the horizontal plate 53. The end of the horizontal plate 53 near the notch 51 is also tilted downward, guiding the filter cake to move towards the notch 51, and finally accurately guiding the filter cake into the crusher 6 at the notch 51.

[0036] As the filter cake slides along the inclined plate 52 and the horizontal plate 53, it will collide and be squeezed with the crushing rod 54. The larger filter cake blocks will be crushed into smaller pieces under the action of the crushing rod 54, which prepares for the subsequent fine crushing work of the crusher 6, reduces the workload of the crusher 6, and improves the overall crushing efficiency.

[0037] like Figure 3 and Figure 5 As shown, in one embodiment, the crusher 6 includes a mounting frame 61 disposed inside the notch 51, a housing 62 disposed on one side of the mud storage hopper 3, and a reducer 63 and a drive motor 64 disposed on one side of the housing 62. Two crushing rollers 65 are rotatably mounted inside the mounting frame 61, and two rotating shafts 66 are rotatably mounted inside the outer shell 62. One end of each rotating shaft 66 is connected to a corresponding crushing roller 65. Gears 67 are mounted on both rotating shafts 66, and the two gears 67 mesh with each other. The output shaft of the drive motor 64 is connected to the input shaft of the reducer 63, and the output shaft of the reducer 63 is connected to the other end of any rotating shaft 66. The other end of the other rotating shaft 66 is rotatably connected to the inner wall of the outer shell 62. Multiple through holes are provided on the outer shell 62 and the sludge storage hopper 3 for the extension of the rotating shaft 66.

[0038] After the drive motor 64 starts, its output shaft begins to rotate, transmitting power to the input shaft of the reducer 63 connected to it. The reducer 63 reduces the speed and increases the torque of the high-speed rotating power input from the drive motor 64, and then transmits the power to one of the rotating shafts 66.

[0039] Since both rotating shafts 66 are equipped with meshing gears 67, when one rotating shaft 66 rotates under the drive of the reducer 63, it will drive the other rotating shaft 66 to rotate in the opposite direction through the meshing transmission of the gears 67, thus realizing the synchronous reverse rotation of the two rotating shafts 66. One end of the rotating shaft 66 is connected to two crushing rollers 65 that rotate in opposite directions inside the mounting frame 61. When the two rotating shafts 66 rotate synchronously in opposite directions, they will drive the two crushing rollers 65 to rotate synchronously in opposite directions as well.

[0040] In this way, the filter cake enters the mounting frame 61 through the notch 51 and is subjected to various forces such as compression, shearing and grinding between the two relatively rotating crushing rollers 65, thereby being broken into smaller particles and completing the crushing process.

[0041] like Figure 3 and Figure 5 As shown, in one embodiment, the sludge storage hopper 3 is a conical hopper that is wider at the top and narrower at the bottom, with an open top. The sludge storage hopper 3 has a chamber inside for storing filter cake residue.

[0042] Because the upper part of the sludge storage hopper 3 is open, during the operation of the equipment, the filter cake residue after the previous treatment falls into the sludge storage hopper 3. The cone shape, which is wider at the top and narrower at the bottom, makes the opening area larger, which can more efficiently receive the filter cake falling from above and ensure that the filter cake residue smoothly enters the internal chamber of the sludge storage hopper 3 for storage.

[0043] like Figure 6 As shown, in one embodiment, the conveying component 7 includes a conveying channel 71 disposed below the interior of the sludge storage hopper 3. The conveying channel 71 is semi-circular, and a through hole 72 communicating with the discharge valve 8 is provided on the conveying channel 71. A spiral conveying rod 73 is rotatably installed inside the conveying channel 71. A second drive motor 74 and a second reducer 75 are installed on one side of the mud storage hopper 3. The output shaft of the second drive motor 74 is connected to the input shaft of the second reducer 75. The output shaft of the second reducer 75 is connected to the end of the spiral conveying rod 73 away from the through hole 72.

[0044] The filter cake residue stored in the sludge storage hopper 3 gradually accumulates downwards under the action of gravity and enters the semi-circular conveying channel 71.

[0045] After the drive motor 2 74 starts, its output shaft begins to rotate, transmitting power to the input shaft of the reducer 2 75 connected to it. The reducer 2 75 reduces the speed and increases the torque of the high-speed rotational power input from the drive motor 2 74, and then transmits the power to the screw conveyor 73.

[0046] Driven by power, the screw conveyor 73 begins to rotate within the conveying channel 71. As the screw conveyor 73 rotates, its helical blades push the filter cake residue entering the conveying channel 71 forward along the length of the conveying channel 71, thus conveying the filter cake residue within the conveying channel 71 and allowing it to flow into the through hole 72, where it is discharged through the discharge valve 8.
