Description

Technical Field

[0001] The utility model relates to the technical field of filter presses, in particular to a mud storage hopper for a filter press. Background Art

[0002] A filter press is a device that uses pressure to separate water from sludge, and is usually used in the solid-liquid separation process. It consists of multiple filter chambers and pressure devices, and the sludge is squeezed out by pressure to achieve separation. In the process of using a filter press, a sludge storage hopper is required to store the separated sludge. This is because the sludge storage hopper can easily collect and process the sludge to prevent it from polluting the environment. At the same time, the sludge storage hopper can also adjust the storage volume and treatment method of the sludge according to needs, thereby improving the efficiency of the entire solid-liquid separation process.

[0003] In traditional filter press operation, the function of the mud hopper is to collect and store the sludge filtered out during the filtration process. When the filter press is working, the sludge is filtered and compressed, the water in it is squeezed out, and the solid particles remain on the filter cloth to form a filter cake. As the filtration proceeds, the filter cake will gradually increase, and the mud hopper plays the role of temporarily storing these filter cakes. When the mud hopper is full, the next step of sludge treatment can be carried out, such as transportation, drying or further disposal.

[0004] When the above-mentioned conventional mud storage hopper for filter press is in use, since the mud storage hopper is usually designed for temporary storage of mud cake, its structure is not conducive to direct drying operation, resulting in the mud storage hopper frequently reaching a full load state, limiting the use efficiency of the mud storage hopper.

The inner wall of the fixed plate 2 is fixedly connected with a feed plate 10, and the outer wall of the hopper 1 is provided with a support assembly, which is used to support the hopper 1. The inner wall of the hopper 1 is fixedly connected with a fan 11, and the support assembly includes a support frame 12, the inner wall of the support frame 12 is fixedly connected to the outer wall of the hopper 1, and the outer wall of the support frame 12 is fixedly connected with a connecting plate 13;

[0026] Specifically, the mud is first placed above the screening plate 6, and then the driving motor 3 is started. Its power is transmitted to the eccentric wheel 5 through the rotating column 4. The rotation of the eccentric wheel 5 produces an up and down reciprocating motion, which in turn pushes the screening plate 6 to vibrate. In this process, the telescopic rod 7 plays a guiding role to ensure that the movement trajectory of the screening plate 6 is accurate. At the same time, the buffer spring 8 plays a role in reducing impact and vibration to protect the equipment from damage. During the screening process, the moisture in the mud is separated and collected and transported by the conveying mechanism above the unloading plate 10. The screened mud falls from one end of the screening plate 6 into the inside of the hopper 1. In order to accelerate the drying process of the mud, the fan 11 is started to quickly air-dry the falling mud to improve the drying efficiency of the mud.

[0027] Reference Figure 1 and Figure 4The bottom of the hopper 1 is fixedly connected to the inside of the connecting plate 13, the inside of the connecting plate 13 is slidably connected with a sealing plate 14, the inside of the connecting plate 13 is fixedly connected with a motor 2 15, the output end of the motor 2 15 is fixedly connected with a rotating rod 16, both ends of the rotating rod 16 are rotatably connected to the inside of the connecting plate 13, both ends of the rotating rod 16 are fixedly connected with a gear 17, the outer wall of the sealing plate 14 is fixedly connected with a rack 18, the rack 18 is meshed with the gear 17, and the outer wall of the rack 18 is slidably connected to the inside of the connecting plate 13;

[0028] Specifically, the rotation of the driving motor 15 is transmitted through the rotating rod 16, and the rotating rod 16 is connected to two gears 17. The rotation of the gear 17 causes the racks 18 fixed on the upper and lower sides of the hopper 1 to move in the opposite direction, which is further converted into the opening and closing action of the sealing plate 14, thereby realizing flexible control of the hopper 1 and facilitating the loading and unloading of mud.

[0029] Reference Figure 1 and Figure 5 The outer wall of the support frame 12 is fixedly connected to a delivery pipe 19, the interior of the delivery pipe 19 is rotatably connected to a fixed column 20, the interior of the delivery pipe 19 is fixedly connected to a motor 3 22, the output end of the motor 3 22 is connected to the fixed column 20, the outer wall of the fixed column 20 is fixedly connected to an auger blade 21, and the outer wall of the auger blade 21 is rotatably connected to the inner wall of the delivery pipe 19;

[0030] Specifically, the rotation of the driving motor three 22 is transmitted to the inside of the conveying pipe 19 through the fixed column 20. The fixed column 20 is connected to the auger blade 21. The rotation of the auger blade 21 continuously conveys the dried mud from the hopper 1 to the next link, ensuring the efficient and stable operation of the mud storage hopper of the filter press.

[0031] Working principle: When the mud storage hopper for the filter press is needed, first place the mud on the top of the screening plate 6, then drive the motor 3 to drive the rotating column 4 and the eccentric wheel 5 to rotate, so that the screening plate 6 is pushed up and down by the eccentric wheel 5. During this process, the telescopic rod 7 is used for guidance, and the buffer spring 8 is used for buffering, thereby driving the moisture in the mud to be screened out and transported to the top of the discharge plate 10. The screened mud falls into the interior of the hopper 1 through one end of the screening plate 6. At this time, the fan 11 is used to quickly dry the falling mud;

[0032] In addition, the second driving motor 15 drives the rotating rod 16 to rotate, thereby driving the two gears 17 to rotate through the two ends of the rotating rod 16, and then the rotation of the gear 17 drives the racks 18 on the upper and lower sides to move in the opposite direction, thereby driving the sealing plate 14 to open and close the hopper 1, thereby realizing flexible opening and closing;

[0033] Finally, the driving motor 3 22 drives the fixed column 20 to rotate inside the conveying pipe 19, thereby driving the auger blade 21 inside the conveying pipe 19, and then continuously conveying the dried mud material.
