Description

Technical Field

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

[0002] The working principle of a filter press is to use a pressure pump to press slurry into a closed filter chamber formed by two adjacent filter plates, creating a pressure difference on both sides of the filter cloth, thereby achieving solid-liquid separation. A filter press generally consists of a head plate, a tail plate, filter plates, a hydraulic cylinder, a main beam, a transmission and a pulling device. The hydraulic cylinder piston pushes the head plate to move, causing the filter plates to press against the adjacent filter plates to form a filter chamber. The mud pump delivers the mud into the filter chamber, and the water penetrates the filter cloth and is discharged through the drain port. The solid mud forms a filter cake in the filter chamber. When the mud fills the filter chamber, the high-pressure pump continues to pressurize the mud to separate the solid and liquid in the filter chamber.

[0003] For example, the patent with announcement number CN207324193U discloses a cleaning mechanism of a filter press, which includes a machine base, on which are provided a plurality of filter plates arranged along the length direction of the machine base, a filter press chamber is formed between two adjacent filter plates, filter cloths covering the inner wall of the filter press chamber are provided on the filter plates, and a scraper member that contacts the filter cloths on the two adjacent filter plates and a drive assembly that drives the scraper member to slide along the height direction of the machine base is provided on the machine base; although the cleaning mechanism of the filter press adopts a scraper member and a drive assembly to scrape the material on the filter cloth, and sucks away the scraped material through the suction mechanism to achieve a better cleaning effect; however, in actual use, due to the certain adhesion between the filter residue and the filter screen, when the scraper member is directly used to clean the filter screen, the filter residue is difficult to quickly separate from the filter screen, which will increase the time required for cleaning, so it needs to be improved.

[0028] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments. It should be understood that the embodiments are merely for explanation of the present invention and are not intended to limit the present invention.

[0029] The following is combined with Figure 1-Figure 5 This embodiment is described in further detail.

[0030] See also Figure 1-3 In this embodiment, a sludge cleaning mechanism for a filter plate of a filter press includes a cleaning box 100, a cleaning chamber 101 for placing a filter plate 120 is provided in the cleaning box 100, and slots 201 are provided on opposite side walls of the cleaning chamber 101. Blocks 301 that extend into the corresponding slots 201 are provided on the upper side and at both ends of the filter plate 120, and an impact component for impacting the filter plate 120 is provided in the cleaning chamber 101 and on one side of the filter plate 120. The impact component can be raised and lowered, and a cleaning component for cleaning the filter plate 120 is provided in the cleaning chamber 101 and on the other side of the filter plate 120.

[0031] In this embodiment, combined with Figure 3As shown, both sides of the filter plate 120 are recessed inward to form a filter groove 300, and a filter cloth is installed in the filter groove 300. When it is necessary to clean the filter residue remaining on the filter cloth on the filter plate 120, the filter plate 120 is removed from the existing filter press, and the clamping block 301 is inserted into the corresponding clamping groove 201. The filter plate 120 is then placed in the cleaning chamber 101 for cleaning.

[0032] The impact assembly is provided so that the impact assembly can repeatedly impact the filter plate 120, thereby loosening and dropping the filter residue remaining on one side of the filter cloth; the cleaning assembly is provided so that the filter residue remaining on the other side of the filter cloth can be cleaned. In actual use, the filter plate 120 can be turned over and installed so that the impact assembly and the cleaning assembly can process the other side of the filter cloth, thereby improving the cleaning effect of the filter cloth;

[0033] The impact assembly can be raised and lowered so that it can impact the filter plate 120 at different heights, thereby impacting different positions of the filter cloth, thereby increasing its applicability.

[0034] like Figure 1-5 As shown, in this embodiment, the impact assembly includes a fixed plate 510 arranged in the cleaning chamber 101, and a rotatable first gear 610 is relatively provided on the lower side of the fixed plate 510, and a rotatable driven shaft 620 is relatively provided on the lower side of the fixed plate 510 and located on both sides of the corresponding first gear 610. A second gear 622 meshing with the first gear 610 is provided on the driven shaft 620, and a half gear 621 is also provided on the driven shaft 620. A movable impact bar 522 is also provided on the lower side of the fixed plate 510, and tooth grooves meshing with the corresponding half gear 621 are respectively provided on both sides of the impact bar 522. The rotation of the first gear 610 is used to drive the impact bar 522 to move back and forth to impact the filter plate 120.

[0035] In this embodiment, the first gear 610 is rotatably mounted on the upper side of the fixing plate 510 via a driving shaft, wherein the first gear 610 is rotatably mounted on the upper side of the fixing plate 510 via a driving shaft. Figure 5 As shown, the lower side surface of the fixed plate 510 is provided with a limit frame 520 located at the edge, and the two ends of the impact bar 522 are arranged through the corresponding limit frames 520, thereby realizing the sliding installation of the impact bar 522 between the limit frames 520. In order to prevent the impact bar 522 from detaching and sliding out of the limit frame 520, the two ends of the impact bar 522 are bent to form a limit portion 521.

[0036] In this embodiment, the first gear 610 rotates, thereby driving the second gear 622 and the driven shaft 620 to rotate accordingly, and the oppositely arranged half gears 621 sequentially contact the tooth grooves on both sides of the impact bar 522. When the half gear 621 on one side contacts the tooth groove on one side of the impact bar 522, the impact bar 522 moves toward the filter plate 120 and impacts the filter plate 120. When the half gear 621 on the other side contacts the tooth groove on the other side of the impact bar 522, the impact bar 522 moves in a direction away from the filter plate 120. This process is repeated, so that the impact bar 522 can repeatedly impact the filter plate 120. In order to increase the impact effect of the impact bar 522, an impact head 531 is provided on the end of the impact bar 522 facing the filter plate 120.

[0037] In actual use of this embodiment, a motor for driving the corresponding first gear 610 to rotate is provided on the upper side of the fixing plate 510, wherein the motor is a waterproof motor.

[0038] like Figure 1-5 As shown, in this embodiment, a bracket 130 is provided in the cleaning chamber 101, a lifting chamber is provided between the brackets 130, a fixed plate 510 is liftably provided in the lifting chamber, a rotatable rotating shaft 500 is provided in the lifting chamber, and the rotating shaft 500 is threaded through the fixed plate 510, and the rotation of the rotating shaft 500 is used to drive the fixed plate 510 to move up and down in the lifting chamber.

[0039] In this embodiment, the bracket 130 is fixedly installed in the cleaning chamber 101 in the vertical direction, and the two ends of the rotating shaft 500 are rotatably installed in the lifting chamber through bearings, thereby realizing the rotatable setting of the rotating shaft 500. Since one side wall of the fixed plate 510 slides against the side wall of the lifting chamber, when the rotating shaft 500 is rotated, the fixed plate 510 will move along the axial direction of the rotating shaft 500, thereby driving the impact bar 522 and the impact head 531 to impact different heights of the filter plate 120, so that the filter residue at more positions is loosened, and the use effect is better.

[0040] like Figure 1-5 As shown, in this embodiment, the top end of the rotating shaft 500 extends out of the bracket 130 , and a hand-cranked wheel 501 is provided at the protruding end of the rotating shaft 500 .

[0041] In this embodiment, the provision of the hand-cranked wheel 501 allows the operator to increase the force application points when rotating the rotating shaft 500, making it more convenient to use.

[0042] like Figure 1-2 As shown, in this embodiment, the cleaning assembly includes a water tank 110 arranged outside the cleaning box 100, and the water tank 110 is provided with a water pipe 111 for spraying water in the water tank 110 to the other side of the filter plate 120.

[0043] In this embodiment, the water tank 110 is used to store tap water, and a water pump located inside the water tank 110 is provided on the water pipe 111. The water pump is used to spray the water in the water tank 110 through the water pipe 111 to the other side of the filter plate 120, thereby washing the filter residue thereon.

[0044] like Figure 1-4 As shown, in this embodiment, limiting grooves 202 are provided on the opposite side walls of the cleaning chamber 101, and the cleaning assembly also includes a movable cleaning plate 400, and both sides of the cleaning plate 400 are slidingly arranged in the limiting grooves 202, and bristles 401 are provided on the side of the cleaning plate 400 close to the filter plate 120.

[0045] In this embodiment, the setting of the limiting groove 202 restricts the movement direction of the cleaning plate 400, that is, it can only move along the extension direction of the limiting groove 202. Even if the cleaning plate 400 can only move up and down in the cleaning chamber 101, the bristles 401 can brush the loose filter residue on the other side of the filter plate 120, and cooperate with the rinsing of the water pipe 111 to achieve a better cleaning effect of the cleaning assembly.

[0046] In order to facilitate the movement of the cleaning plate 400 , a handle 402 is provided on the cleaning plate 400 .

[0047] After that, the filter plate 120 is removed from the filter press, and then the filter plate 120 is placed in the cleaning chamber 101, and the motor is started to rotate the first gear 610, so that the impact bar 522 and the impact head 531 repeatedly impact the filter residue on one side of the filter plate 120 to loosen the filter residue. Then, the water pump is started to allow the water in the water storage tank 110 to flush the other side of the filter plate 120 through the water pipe 111, so that the loosened filter residue can be separated from the filter cloth on the filter plate 120. At the same time, the handle 402 is moved up and down to drive the cleaning plate 400 to move, and the bristles 401 can brush the filter residue on the filter plate 120 to separate the filter residue from the filter plate 120. Then, the filter plate 120 is removed, the two sides of the filter plate 120 are turned over, and the filter plate 120 is placed in the cleaning chamber 101 again, and the above operation is repeated, so that the filter plate 120 can be better cleaned.

[0048] In short, the above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention patent.
