Description

Technical Field

[0001] The utility model relates to the technical field of filter press cleaning, in particular to a filter press capable of automatically washing filter plates. Background Art

[0002] The filter press uses a special filter medium to apply a certain pressure to the object, so that the liquid is dialyzed out. It is a commonly used solid-liquid separation equipment. It was used in chemical production in the early 18th century and is still widely used in chemical, pharmaceutical, metallurgical, dye, food, brewing, ceramic and environmental protection industries. After the filter press is filtered, the filter residue of the filtered material will remain on the filter press plate, which will affect the subsequent filtration of the material. Therefore, the filter press plate needs to be rinsed to remove the residue.

[0003] The prior art publication number is CN109173366A, which is an automatic flushing system for a filter press plate. The device is provided with a water spray pipe to spray water on the filter press plate, but the device only flushes part of the filter press plate during flushing. When the flushing of this part is completed, the mobile workbench drives the water spray pipe to move to the next part of the filter press plate, so that the overall flushing time is long and the flushing efficiency is low. Moreover, the device is provided with a water spray pipe on one side of the filter press. After the water is sprayed out from this side, it is parabolic under the action of gravity, so that the top of the filter press plate away from the water spray pipe cannot be completely covered by the water flow, resulting in incomplete and insufficient flushing and poor flushing effect.

[0021] According to the overall structure of the device, after the filtration is completed, the cylinder 3 drives the push plate 4 to leave the filter press plate 5, and the filter press plates 5 are separated one by one. Then, the water pump 10 is started, and the water pump 10 conveys the water in the water tank 9 to the spray pipe 14 through the water pipe 11. The filter residue on the filter press plate 5 is washed away through the spray pipe 14, and the washed sewage falls into the water tank 7 and is discharged through the drain pipe.

[0022] like Figure 1 As shown, springs are fixedly connected between two adjacent filter press plates 5 and between the filter press plate 5 and the vertical plate 2 , and four springs are provided. The four springs are distributed at the four corners of the filter press plate 5 and are sleeved on the outside of the fixing rod 12 .

[0023] By arranging springs between the filter press plates 5, when the push plate 4 pushes the filter press plates 5 to be squeezed together, the filter press plates 5 squeeze the springs through the fixed blocks 6. When the push plate 4 releases the filter press plates 5, the filter press plates 5 can be quickly separated under the elastic force of the springs, thereby facilitating the subsequent movement of the spray pipe 14 to between the filter press plates 5 for flushing.

[0024] like Figure 3 As shown, a plurality of spray pipes 14 are provided, and the plurality of spray pipes 14 are spaced apart from the filter press plate 5 . A plurality of linearly arranged spray heads are fixedly connected to both sides of the spray pipe 14 .

[0025] By arranging a plurality of spray pipes 14 distributed at intervals between the filter press plates 5, both sides of the filter press plates 5 can be flushed at the same time.

[0026] like Figure 3 , 4 As shown, a motor 20 is fixedly connected to the top of the frame 1, and a screw 13 is fixedly connected to the protruding end of the motor 20. A movable block 16 is threadedly connected to the screw 13, and a connecting plate is movably connected to the bottom of the movable block 16. The connecting plate is slidably connected to the spray pipe 14. The screw 13 is composed of studs 1301 fixedly connected at two ends, and the connecting plate is composed of two cross-shaped movably connected movable plates 18. The tops of the two movable plates 18 are both movably connected to the movable blocks 16, and the movable blocks 16 are provided with threaded holes matching the adjacent studs 1301. The bottoms of the two movable plates 18 are both slidably connected to the spray pipe 14. The top of the spray pipe 14 is fixedly connected to a fixed plate 17, and a slide groove with a cross-shaped cross-section is provided on the top of the fixed plate 17. The bottom of the connecting plate is inserted into the slide groove, and the left and right sides of the fixed plate 17 are fixedly connected to brushes 15.

[0027] The motor 20 drives the screw 13 to rotate. When the screw 13 rotates, the two movable blocks 16 are relatively moved by the screw 1301 that is screwed in opposite directions, thereby driving the two movable plates 18 to deflect inward, and driving the fixed plate 17 and the spray pipe 14 to move downward in turn. The filter press plate 5 is completely and fully rinsed through the downward spray pipe 14. At the same time, the brush 15 moves downward with the fixed plate 17 to wash the filter press plate 5, thereby strengthening the removal of the filter residue.

[0028] like Figure 3 As shown, a cover body 8 is fixedly connected to the top of the frame 1, a water pipe 11 is fixedly connected to the outside of the cover body 8, and a hose passes through the cover body 8, a motor 20 is fixedly connected in the cover body 8, a plurality of screw rods 13 are provided, and the plurality of screw rods 13 are movably connected in the cover body 8, and gears 19 are fixedly connected to the plurality of screw rods 13, and adjacent gears 19 are meshed with each other.

[0029] The cover body 8 covers the screw 13, the motor 20 and other components to provide protection for the motor 20, the screw 13 and the like to avoid damage, and will not affect the up and down movement of the spray pipe 14. A gear 19 is provided to transmit the power of the motor 20 to other screws 13, so that several screws 13 rotate synchronously and several spray pipes 14 move up and down synchronously.

[0030] Working principle: When in use, the device is connected to an external power supply. After the filtration is completed, the cylinder 3 drives the push plate 4 to move away, and the filter press plate 5 is separated under the action of the spring. At this time, the motor 20 is started, and the motor 20 drives the screw 13 to rotate, and drives several screws 13 to rotate synchronously through the gear 19. When the screw 13 rotates, the movable block 16 is moved relative to each other through the two studs 1301 rotating in opposite directions, so that the two movable plates 18 are relatively deflected, pushing the fixed plate 17 to move downward, and driving the spray pipe 14 to move downward, and the filter press plate 5 is fully and completely rinsed and washed from top to bottom, and the two sides of several filter press plates 5 are rinsed at the same time through several spray pipes 14, with high cleaning efficiency and full and complete cleaning.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
