Description

Technical Field

[0001] The utility model relates to the technical field of filter presses, in particular to a filter plate unloading transmission structure for a filter press. Background Art

[0002] Filter press is an important equipment widely used in chemical, pharmaceutical, food and other industries to achieve solid-liquid separation. It uses a certain number of filter plates to be closely arranged in a row under the action of strong mechanical force. A filter chamber is formed between the filter plates. The filter material is sent into the filter chamber under strong positive pressure. The solid part of the filter material entering the filter chamber is intercepted by the filter cloth to form a filter cake, and the liquid part passes through the filter medium and is discharged from the filter chamber, thereby achieving the purpose of solid-liquid separation. During long-term use, the particles in the material will adhere to the filter cloth. As the particles accumulate and increase, the filtering performance of the filter cloth will be blocked, making it difficult to discharge the liquid and affecting the normal use of the filter press. Therefore, the filter cloth needs to be cleaned frequently.

[0003] After the solid-liquid separation is completed, some filter presses need to use a unloading device to separate the compressed filter plates one by one, and then discharge the separated solid material from between the filter plates. Since the compressed filter plates need to be separated one by one and then the solid material needs to be discharged, the operation is cumbersome and the work efficiency is seriously delayed.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-3, the embodiment proposed in the present application is: a filter plate unloading transmission structure for a filter press, comprising a filter press body 1, a plurality of filter press plates 2 are arranged on the left side of the filter press body 1, and a fixing plate 3 is fixedly arranged at the left and right ends of the plurality of filter press plates 2 on the upper side of the filter press body 1, and a first guide rod 4 is fixedly arranged transversely between the fixing plates 3, and the first guide rod 4 passes through the upper ends of the plurality of filter press plates 2 and is slidably connected thereto, a hydraulic cylinder 5 is arranged on the right side of the filter press body 1, and a pushing plate 6 is fixedly arranged at one end of the hydraulic cylinder 5 corresponding to the filter press plate 2, and a connecting structure 7 is movably arranged on the upper side of the adjacent filter press plates 2, and a plurality of connecting structures 7 are respectively located on the left and right sides of the first guide rod 4 and are staggered, and a winding structure 8 is arranged at the right upper end of the filter press body 1 at the right side of the right fixing plate 3 corresponding to the filter press plate 2, and the winding structure 8 passes through the fixing plate 3 to the left and is fixedly connected to the rightmost filter press plate 2;

[0025] By setting up multiple connecting structures 7 and cooperating with the winding structure 8, multiple filter press plates 2 can be simultaneously controlled to be compressed or separated in sequence during compression or separation, thereby greatly improving the working efficiency of the filtration. The filter press and its working principle of filtration here are existing technologies well known to technicians in this field and will not be elaborated here.

[0026] In another embodiment, see Figure 1 and 3 The connection structure 7 includes two fixing blocks 71, which are respectively fixed on the upper side surfaces of two adjacent filter press plates 2. The upper ends of the two fixing blocks 71 are respectively provided with connecting pieces 72. The lower ends of the two connecting pieces 72 are hinged to the corresponding fixing blocks 71. The upper ends of the two connecting pieces 72 are hinged to each other. At the same time, a limiting support block 73 is provided on the opposite side of the two fixing blocks 71. When the corresponding connecting piece 72 rotates along the hinge position to abut against the upper side of the corresponding limiting support block 73, the connecting piece 72 is in an inclined upward state.

[0027] When the filter press is working, the hydraulic cylinder 5 drives the push plate 6 to move to the left to compress the multiple filter press plates 2. During the compression of the multiple filter press plates 2, the bottoms of the two mutually hinged connecting pieces 72 on the upper sides of the adjacent filter press plates 2 rotate along the hinged position, approach each other, and the tops move upward to be in a contracted state, and at the same time will not affect the filtration work of the adjacent filter press plates 2;

[0028] After the filtration is completed, the hydraulic cylinder 5 contracts, and then the winding structure 8 is wound up, thereby driving the rightmost filter press plate 2 to move to the right. At this time, the connecting pieces 72 between the adjacent filter press plates 2 drive the adjacent filter press plates 2 to separate in turn, until the connecting pieces 72 rotate along the hinge position to abut against the upper side of the corresponding limit support block 73. At this time, the connecting pieces 72 are in an inclined upward state. Figure 2To ensure this state, when the filter press is performed on the lower side, the two connecting pieces 72 can be smoothly retracted along the hinged position.

[0029] In another embodiment, see Figure 1 and 3 The winding structure 8 includes a winding wheel 81, which is arranged on the upper side of the filter press body 1 and is located on the right side of the right fixed plate 3. A support frame 82 is provided on the upper side of the filter press body 1 corresponding to the winding wheel 81. The winding wheel 81 is rotatably connected to the support frame 82. A rope 83 is fixedly provided on the surface of the winding wheel 81. The rope 83 passes through the right fixed plate 3 to the left and extends to the rightmost filter press plate 2. A through hole 84 is opened at the right fixed plate 3 corresponding to the rope 83. A connecting ring 21 is provided on the rightmost filter press plate 2 corresponding to the rope 83. The rope 83 is fixed to the rightmost filter press plate 2 through the connecting ring 21. A forward and reverse motor 85 is fixedly provided on the upper side of the filter press body 1 corresponding to the support frame 82. The driving end of the forward and reverse motor 85 is drivingly connected to the winding wheel 81.

[0030] When the filter press is working, the hydraulic cylinder 5 drives the push plate 6 to move to the left to compress the multiple filter press plates 2. At this time, the forward and reverse motors 85 cooperate with the filter press plates 2 moving to the left to release the rope 83 on the winding wheel 81; after the filtration work is completed, the hydraulic cylinder 5 contracts, and then the forward and reverse motors 85 rotate to drive the winding wheel 81 to wind up the rope 83, thereby driving the rightmost filter press plate 2 to cooperate with the connecting structure 7 to drive the multiple filter press plates 2 to move to the right and separate in turn. The forward and reverse motors 85 and the control method here are all existing technologies and will not be elaborated here.

[0031] In another embodiment, see Figure 1 and 3 Connecting columns 11 are transversely arranged at the front and rear sides of the upper side surface of the filter press body 1 corresponding to the plurality of filter press plates 2, and sliding grooves 12 are respectively opened on the opposite sides of the two connecting columns 11, and sliding blocks 22 slidably connected therewith are respectively arranged at the two sliding grooves 12 corresponding to the front and rear sides of the plurality of filter press plates 2; second guide rods 13 are transversely arranged in the two sliding grooves 12, and the second guide rods 13 pass through the sliding blocks 22 and are slidably connected therewith; by arranging the sliding grooves 12 and the second guide rods 13 at the front and rear sides of the plurality of filter press plates 2, in cooperation with the sliding blocks 22, the compression or separation sliding of the plurality of filter press plates 2 can be made smoother.
