Description

Technical Field

[0001] The present application relates to the technical field of sludge filter press, and specifically to a sludge filter press. Background Art

[0002] Sludge is an inevitable product of the sewage treatment process. It contains a large amount of water and solid particles. In order to effectively treat and dispose of sludge, it is necessary to separate the water and solid particles. Filter pressing is an effective solid-liquid separation technology that can squeeze out the water in the sludge to obtain relatively dry sludge solids.

[0003] The plate and frame sludge filter press is a type of sludge filter press. It uses efficient dehydration to separate the water in the sludge through the filter medium (filter cloth), thereby achieving solid-liquid separation.

[0004] For example, the patent with publication number CN207520671U discloses a sludge filter press. This patent uses a filter residue compacting device to reprocess the filter residue, reducing dust pollution while compacting the filter residue into filter residue blocks, making it more convenient to transport the filter residue. At the same time, the filter residue blocks can be reused, protecting the environment while improving resource utilization. The improved diaphragm filter plate is more convenient to replace and improves work efficiency.

[0005] However, after the filtration is completed, the sludge may be too thick or contain sticky substances, which may make it difficult for the filter cake to fall off the filter cloth or some residue may remain on the filter plate after falling off. The residual residue will occupy the filtration area of ​​the filter cloth, resulting in reduced filtration efficiency. Long-term residue may also cause equipment corrosion or damage, further exacerbating safety hazards.

[0006] Therefore, it is necessary to provide a sludge filter press to solve the above problems.

[0007] It should be noted that the above information disclosed in this Background section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute prior art. Summary of the Invention

[0034] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0035] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0036] like Figures 1-3As shown, the present application provides a sludge filter press, comprising a frame body 1, and a filter press mechanism 2 fixedly arranged on the upper end of the frame body 1, which is a plate and frame filter press commonly used in the prior art and suitable for the present embodiment, for filtering sludge by applying pressure to achieve solid-liquid separation;

[0037] The filter press mechanism 2 comprises a plurality of filter plates 21 for supporting filter cloth and providing a filtering surface;

[0038] Meanwhile, in order to facilitate the removal of filter cakes between the filter plates 21 after filtration is completed, a pull plate mechanism 3 is fixedly arranged on both sides of the filter press mechanism 2 on the frame body 1, which is used to pull apart the filter plates 21 one by one after filtration is completed so that the filter cakes can be removed by the staff;

[0039] The pull plate mechanism 3 comprises a mounting plate (not shown in the figure) fixedly arranged on both sides of the frame body 1, and a displacement assembly 30 fixedly arranged on the upper end of the mounting plate, which is a lead screw transmission mechanism commonly used in the prior art and suitable for the present embodiment. Meanwhile, the displacement assembly 30 has two first sliding blocks 301, so that the first sliding blocks 301 can move linearly under the driving of the displacement assembly 30;

[0040] Meanwhile, a pulling assembly 31 is fixedly arranged on the first sliding blocks 301, which is used to clamp the filter plates 21 to pull them apart one by one;

[0041] The pulling assembly 31 comprises a mounting column 310 fixedly arranged on the upper end of the two first sliding blocks 301, a fixed plate 311 fixedly arranged on the mounting column 310 at a position parallel to the filter plates 21, a first air cylinder 312 fixedly arranged on the fixed plate 311, and a clamping block 313 fixedly connected to the output end of the first air cylinder 312, so that the clamping block 313 can be moved by starting the first air cylinder 312;

[0042] It should be noted that the clamping block 313 is arranged on both sides of the filter plates 21 to facilitate the fixation of the filter plates 21, so that the pulling operation can be smoothly performed. Meanwhile, the clamping block 313 is in a "concave" shape and is in a parallel position with the filter plates 21. When the filter plates 21 need to be pulled out, the first sliding blocks 301 are first moved by the displacement assembly 30 until the first sliding blocks 301 drive the clamping block 313 to align with both sides of the filter plates 21, and then the movement stops;

[0043] At this time, the first air cylinder 312 can be started to continuously approach the clamping block 313 to both sides of the filter plates 21 until the inside of the clamping block 313 touches the filter plates 21, and then the movement stops. Subsequently, the displacement assembly 30 drives the first sliding blocks 301 to move the filter plates 21, so as to achieve the purpose of pulling the filter plates 21. Meanwhile, the filter cakes between the filter plates 21 will fall into the container prepared in advance under the influence of gravity.

[0044] Finally, after the filter plate 21 is pulled to the designated position, the first cylinder 312 can drive the clamping block 313 away from the filter plate 21, thereby performing the next group of pulling operations;

[0045] like Figures 2-4 As shown, in order to prevent the filter cake from being difficult to fall off or remaining after falling when the filter plate 21 is pulled, which requires the operator to manually clean it and thus reduces work efficiency, a spray assembly 33 is slidably provided on the mounting column 310. The spray assembly 33 is used to spray and brush the filter plate 21, thereby cleaning the filter plate 21;

[0046] The spray assembly 33 includes a second slider 337 slidably mounted on two sets of mounting posts 310. A second cylinder 330 is fixedly mounted on one side of the lower end of the mounting posts 310. The output end of the second cylinder 330 is fixedly connected to the lower end of the second slider 337. Therefore, activating the second cylinder 330 can drive the second slider 337 to slide along the mounting posts 310.

[0047] A mounting block 331 is fixedly mounted on the second slider 337. Two sets of water pipes 332 are fixedly mounted between the mounting blocks 331. The two sets of water pipes 332 are arranged in parallel and are interconnected. A water inlet 333 is fixedly mounted at the input end of one of the water pipes 332. The water inlet 333 is used to introduce cleaning liquid into the two sets of water pipes 332 for use, and the cleaning liquid can circulate between the two sets of water pipes 332.

[0048] At the same time, multiple groups of connecting pipes 334 are fixedly provided at the lower ends of the two groups of water pipes 332. The connecting pipes 334 are fixedly provided with nozzles 336. The nozzles 336 are used to spray the cleaning liquid on the filter plate 21, thereby achieving the purpose of cleaning the filter plate 21.

[0049] When the filter plate 21 needs to be cleaned, the filter plate 21 is simply pulled to a designated position and the second cylinder 330 is activated to pull the second slider 337 vertically downward along the mounting column 310 .

[0050] It should be noted that at this time, the filter plate 21 is fixed by the block 313 and is located between the two sets of water pipes 332. In addition, the two sets of water pipes 332 move with the second slider 337, and then the cleaning liquid is introduced into the water pipes 332 through the water inlet 333 and evenly sprayed to both ends of the filter plate 21 by the nozzle 336, thereby cleaning the filter plate 21.

[0051] In order to clean the stubborn residue on the filter plate 21, the lower end of the two groups of water pipes 332 is fixedly provided with a baffle 335, and the side of the baffle 335 facing the filter plate 21 is fixedly provided with soft hair 338, which is used for wiping the washed filter plate 21, so that the filter plate 21 can be further cleaned.

[0052] The above only describes the preferred embodiments of the present application and is not used to limit the present application. Those skilled in the art can make various modifications and changes to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
