DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions 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 of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Example: like Figure 1-8 As shown, this embodiment provides a plate-frame filter press that is easy to unload, including a frame 10, on which multiple groups of filter plates 11 are evenly arranged; A support plate 20 is provided below the frame 10, and a receiving hopper 30 is provided on the support plate 20. The receiving hopper 30 is provided directly below the multiple groups of filter plates 11. A displacement frame 50 is provided in the receiving hopper 30, and the displacement frame 50 is in contact with the receiving hopper 30. A driving assembly 40 is provided at the bottom of the support plate 20, and the driving assembly 40 cooperates with the displacement frame 50, so that the displacement frame 50 moves back and forth in the receiving hopper 30 to disturb the mud cake.

[0020] In this embodiment, when the filter plate 11 on the frame 10 drops the mud cake, the mud cake falls into the receiving hopper 30, and the driving assembly 40 drives the displacement frame 50 to move back and forth, so that the displacement frame 50 moves back and forth on the receiving hopper 30, and the mud cakes at different positions in the receiving hopper 30 are disturbed, so that the mud cakes are broken and scraped off; By means of the displacement frame 50 that can be displaced back and forth, the mud cake is effectively crushed and scraped off, thereby improving the feeding efficiency of the filter press and the convenience of mud cake processing. Specifically, the technical solution arranges the displacement frame 50 in the receiving hopper 30, and cooperates with the driving assembly 40 to realize the reciprocal displacement of the displacement frame 50, so that the displacement frame 50 can disturb the mud cake in the receiving hopper 30, thereby achieving the crushing and scraping of the mud cake. This design not only reduces the need for manual intervention and reduces labor intensity, but also improves the degree of automation of mud cake processing and improves the overall working efficiency of the filter press. In addition, by adjusting the displacement speed of the displacement rod 51 to match the frequency of mud cake dropping, the present invention can also adapt to different working conditions to ensure the continuity and stability of mud cake processing.

[0021] Specifically, the displacement frame 50 includes a displacement rod 51; Two groups of elastic contact rods 56 are symmetrically arranged on the displacement rod 51, and the elastic contact rods 56 are in contact with the inner wall of the receiving hopper 30. The elastic contact rods 56 are provided with deformation grooves 57. The displacement rod 51 moves back and forth, so that the two groups of elastic contact rods 56 move back and forth on the inner wall of the receiving hopper 30.

[0022] In this embodiment, when the elastic contact rod 56 is displaced, the elastic contact rod 56 contacts the receiving hopper 30 , and the elastic contact rod 56 can be deformed at the deformation groove 57 through the deformation groove 57 , so as to provide deformation space for the elastic contact rod 56 .

[0023] Specifically, the receiving hopper 30 is provided with two groups of long side inclined plates 32, the two groups of long side inclined plates 32 are symmetrically arranged, and the plurality of groups of filter plates 11 are arranged directly above the long side inclined plates 32; The two groups of elastic contact rods 56 are in contact with the surfaces of the two groups of long-side inclined plates 32 respectively.

[0024] Specifically, a plurality of groups of raised plates 33 are evenly arranged on the surface of the long side inclined plate 32, and the elastic contact rod 56 is displaced on the surface of the long side inclined plate 32 to contact the raised plates 33; The protruding plate 33 is symmetrically provided with two groups of protruding inclined surfaces 34 . The elastic contact rod 56 is provided with a contact inclined surface 55 . The contact inclined surface 55 is matched with the protruding inclined surface 34 .

[0025] In this embodiment, when the displacement frame 50 is reciprocatingly displaced, the displacement rod 51 is displaced, so that the elastic contact rod 56 is displaced on the surface of the long side inclined plate 32. When the mud cake falls onto the long side inclined plate 32, the elastic contact rod 56 disturbs the mud cake to break it, and the elastic contact rod 56 scrapes off the mud cake residue on the surface of the long side inclined plate 32, effectively avoiding the accumulation and adhesion of the mud cake on the long side inclined plate 32. Of course, the multiple groups of raised plates 33 evenly arranged on the surface of the long side inclined plate 32 are adapted to the contact inclined surface 55 on the elastic contact rod 56. When the elastic contact rod 56 is displaced on the long side inclined plate 32, it contacts the raised plate 33 to generate vibration, further promoting the crushing and scraping of the mud cake. This structural design not only improves the efficiency of mud cake processing, but also reduces the equipment maintenance cost and manual cleaning workload caused by mud cake adhesion, thereby realizing the automation and efficiency of the filter press unloading process, and at the same time avoiding the elastic contact rod 56 from registering residual mud cake material, which is convenient for the next crushing and removal process.

[0026] Specifically, the driving assembly 40 includes two sets of fixing plates 43, and the two sets of fixing plates 43 are symmetrically arranged on the sides of the receiving hopper 30; A driving screw 42 is disposed between the two sets of fixing plates 43 , and the driving screw 42 cooperates with the displacement rod 51 to enable the displacement rod 51 to move back and forth.

[0027] In this case, both ends of the driving screw 42 are connected to the bearing seats respectively, and the bearing seats are connected to the fixing plate 43. The bearing seats are not shown in this case.

[0028] Specifically, a driving servo motor 41 is disposed at one end of the driving screw 42, the driving servo motor 41 is transmission-connected to the driving screw 42, and the driving servo motor 41 is disposed on a fixing plate 43; Two groups of driving rods 52 are symmetrically arranged on the displacement rod 51 . The driving rods 52 are provided with threaded sleeves 54 . The two groups of threaded sleeves 54 are respectively threadedly sleeved on the outer walls of the two groups of driving screw rods 42 .

[0029] In this embodiment, when the displacement rod 51 is displaced, the driving servo motor 41 is turned on to drive the driving screw 42 to rotate, and the driving screw 42 cooperates with the threaded sleeve 54 to cause the driving rod 52 to displace, thereby causing the displacement rod 51 to displace.

[0030] Specifically, a T-shaped guide rail 31 is provided on the long side inclined plate 32, the T-shaped guide rail 31 is fixedly connected to the long side inclined plate 32, and the T-shaped guide rail 31 is provided with two groups of guide grooves 311; The driving rod 52 is provided with a guide plate 53 , and the guide plate 53 is provided with a plurality of guide rods 58 . The guide rods 58 are rollably provided with guide wheels 59 , and the guide wheels 59 are slidably provided in the guide grooves 311 .

[0031] In this embodiment, a T-shaped guide rail 31 fixedly connected to the long side inclined plate 32 is provided on the long side inclined plate 32, a guide groove 311 is provided on the T-shaped guide rail 31, a guide plate 53 is provided on the driving rod 52, and a plurality of guide wheels 59 are provided on the guide plate 53. These guide wheels 59 are slidably arranged in the guide groove 311. This design enables the guide wheels 59 to slide smoothly in the guide groove 311, thereby providing stable guidance and support for the displacement rod 51. Moreover, the guide wheel 59 is slidably set in the guide groove 311 to hoist the displacement rod 51, thereby facilitating the hoisting of the drive screw 42. Through this structure, the hoisting of the displacement rod 51 is optimized, which facilitates the hoisting of the drive screw 42, especially for the longer drive screw 42. It can effectively avoid the sagging or falling of the middle part due to the excessive length, which not only improves the installation efficiency and safety of the equipment, but also reduces the maintenance cost and downtime caused by deformation or damage of the drive screw 42, thereby improving the reliability and service life of the entire filter press.

[0032] Specifically, the displacement rod 51, the driving rod 52 and the threaded sleeve 54 are all made of hard materials, and the elastic contact rod 56 is made of elastic material; A plurality of supporting legs 21 are disposed at the bottom end of the supporting plate 20 .

Through the cooperation between the driving screw 42 and the threaded sleeve 54, it is observed whether the displacement rod 51 is displaced in the receiving hopper 30. If it is not displaced, S10 and S20 are repeated until the displacement rod 51 can be smoothly displaced in the receiving hopper 30. S40, displacement disturbance: The filter plate 11 on the frame 10 is displaced so that the mud cake falls into the receiving hopper 30, and at the same time, the servo motor 41 is driven to start, so that the displacement rod 51 moves back and forth, so that the elastic contact rod 56 contacts the mud cake, and the mud cake is disturbed and crushed; S50, speed adjustment: According to the frequency of the mud cake falling in S40, the displacement speed of the displacement rod 51 is adjusted so that the speed of the displacement rod 51 matches the frequency of the mud cake falling.

[0034] Specifically, in S10 , before the two sets of elastic contact rods 56 extend into the receiving hopper 30 through the bottom of the receiving hopper 30 , the guide plate 53 is aligned with the T-shaped guide rail 31 , and the multiple sets of guide wheels 59 are placed in the guide groove 311 .
