Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to a wastewater treatment filter press. Background Technology

[0002] A filter press is a mechanical device that uses a special filter medium to apply pressure to a mixture, extracting solids and achieving solid-liquid separation. Filter plates are the main filtration elements of a filter press. Material filtration involves multiple filter plates arranged on the main beam of the filter press to form filter chambers. The filter plates are covered with filter cloth on both sides, and the chambers are sealed by compression. Material is injected into the filter chambers by a feed pump, where the filter cloth traps particles to form a filter cake. The filtrate is discharged through the filter plate inlet, and the filter cake is removed by a plate puller installed on the filter press, thus achieving solid-liquid separation.

[0003] Currently, because the pressing plate and filter cloth were previously in a parallel state, and the pressing plate and filter cloth are installed vertically inside the machine body, after a long period of squeezing, the filter plate is subjected to greater pressure and is prone to deformation, resulting in a smaller gap between the filter plates, less material capacity, and a smaller filter cake volume, which affects production efficiency.

[0004] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, the purpose of this utility model is to propose a wastewater treatment filter press to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] The technical solution of this utility model is implemented as follows:

[0007] A wastewater treatment filter press includes: a frame, main beams symmetrically arranged on both sides of the frame, and a thrust plate on one side of the frame; a plurality of filter plates and a pressing plate are arranged between the main beams; the plurality of filter plates are located between the thrust plate and the pressing plate; and filter chambers are formed between adjacent filter plates.

[0008] One side of the clamping plate is connected to the output end of the hydraulic cylinder located on one side of the frame. The side of the thrust plate is provided with a feed port. The filter plate located in the filter chamber is provided with through holes and filter protrusions. The surface of the filter plate is provided with a number of guide grooves arranged in a ring array along the through holes.

[0009] Furthermore, the feed inlet is connected to a slurry pump.

[0010] Furthermore, the filter plate is provided with symmetrically arranged limiting feet on both sides, and the limiting feet are movably connected to the main beam.

[0011] Furthermore, filter cloth is provided between the filter plates.

[0012] Furthermore, the filter plate surface is provided with channels for filtrate discharge, and the channels are equipped with discharge valves.

[0013] Furthermore, there are at least four sets of filter protrusions, which are arranged in a ring array along the through hole, and the diameter of the protrusions is 5-6 cm and the height is 2-3 cm.

[0014] The beneficial effects of this utility model are:

[0015] This invention allows slurry to enter the filter plate through the feed inlet, filling the filter chamber with slurry. A hydraulic cylinder pushes the pressing plate and filter plate against the thrust plate, causing solid particles in the slurry to be trapped on the filter cloth to form a filter cake. The purified liquid passes through the filter cloth and is discharged through the liquid outlet valve, achieving slurry dewatering. Furthermore, the filter plate surface is provided with several guide grooves arranged in a ring array along the through holes, resulting in a more uniform distribution of slurry filling in the filter chamber. Combined with the filter protrusions, this minimizes filter plate deformation, stabilizes the filter plate gaps, increases the filter chamber capacity, and increases the weight of a single filter cake, thereby improving the efficiency of the filter press.

[0016] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objectives and other advantages of this invention are realized and obtained through the structures particularly pointed out in the description and the accompanying drawings.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0024] According to an embodiment of the present invention, a wastewater treatment filter press is provided.

[0025] like Figures 1-2 As shown, a wastewater treatment filter press includes: a frame 1, main beams 2 symmetrically arranged on both sides of the frame 1, and a thrust plate 3 on one side of the frame 1; a plurality of filter plates 4 and a pressing plate 5 are arranged between the main beams 2; the plurality of filter plates 4 are located between the thrust plate 3 and the pressing plate 5; and a filter chamber 7 is formed between adjacent filter plates 4.

[0026] One side of the clamping plate 5 is connected to the output end of the oil cylinder 6 located on one side of the frame 1. The side of the thrust plate 3 is provided with a feed port. The filter plate 4 is located in the filter chamber 7 and is provided with through holes 8 and filter protrusions 9. The surface of the filter plate 4 is provided with several guide grooves 10 arranged in a ring array along the through holes 8.

[0027] With the help of the above technical solution, the slurry enters the filter plate 4 through the feed inlet, so that the filter chamber 7 is filled with slurry. The oil cylinder 6 pushes the pressing plate 5 and the filter plate 4 to press against the thrust plate 3, so that the solid particles in the slurry are trapped on the filter cloth to form a filter cake, while the purified liquid passes through the filter cloth and is discharged through the liquid outlet valve, thus realizing the dewatering of the slurry. The filter plate 4 is provided with several guide grooves 10 arranged in a ring array along the through holes 8 on its surface, so that the slurry filling distribution in the filter chamber 7 is more uniform. With the help of the filter protrusions 9, the deformation of the filter plate 4 is small and the gap between the filter plates 4 is stable. At the same time, the material capacity of the filter chamber 7 is increased and the weight of a single filter cake is increased, thus improving the efficiency of the filter press.

[0028] In addition, a slurry pump is connected to the feed inlet.

[0029] In this technical solution, the slurry is fed into the filter plate 4 through the feed inlet using a slurry pump, so that the filter chamber 7 is filled with slurry.

[0030] In addition, the filter plate 4 is provided with symmetrically arranged limiting feet 11 on both sides, and the limiting feet 11 are movably connected to the main beam 2.

[0031] In this technical solution, a pulley can be installed at the bottom of the limiting foot 11 during application, allowing it to slide horizontally along the main beam 2.

[0032] In addition, filter cloth is provided between the filter plates 4. The surface of the filter plates 4 is provided with channels for the filtrate to be discharged, and the channels are equipped with outlet valves.

[0033] Specifically, solid particles in the slurry are trapped on the filter cloth to form a filter cake, while the purified liquid passes through the filter cloth and is discharged through the liquid outlet valve, thus achieving slurry dewatering.

[0034] In addition, there are at least four sets of filter protrusions 9, which are arranged in a ring array along the through hole 8, and the diameter of the protrusions 9 is 5-6 cm and the height of the protrusions is 2-3 cm.

[0035] This technical solution, through the arrangement of four sets of filter protrusions 9 in a ring array, with a diameter of 5-6cm and a protrusion height of 2-3cm, can achieve uniform pressure distribution on the filter plates 4 when they are stacked together, small deformation of the filter plates 4, and stable gap between the filter plates 4. Combined with the increased material capacity and uniform pressure distribution of the guide groove 10, it improves working efficiency.

[0036] In summary, the following effects can be achieved by using the above-mentioned technical solution of this utility model: the slurry enters the filter plate 4 through the feed inlet, filling the filter chamber 7 with slurry. The oil cylinder 6 pushes the pressing plate 5 and the filter plate 4 to press against the thrust plate 3, so that the solid particles in the slurry are trapped on the filter cloth to form a filter cake. The purified liquid passes through the filter cloth and is discharged through the liquid outlet valve, thus achieving slurry dewatering. Furthermore, the filter plate 4 is provided with several guide grooves 10 arranged in a ring array along the through holes 8 on its surface, which makes the slurry filling distribution in the filter chamber 7 more uniform. Combined with the filter protrusions 9, the deformation of the filter plate 4 is small, the gap between the filter plates 4 is stable, and the material capacity of the filter chamber 7 is increased, the weight of a single filter cake is increased, thus improving the efficiency of the filter press.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
