Description

Technical Field

[0001] This utility model relates to the technical field of vertical filter presses, and in particular to a discharge device for a vertical filter press. Background Technology

[0002] Currently, vertical filter presses are the core equipment for solid-liquid separation in the organic matter removal process of alumina. Their specific workflow includes pressure filtration, filter cake formation, solid-liquid separation, and filter cake removal. However, in practical applications, these filter presses suffer from the following problems: the organic filter cake produced during the process is highly viscous and easily remains on the surface of the filter plates, leading to problems such as slag inclusions in the gaps between the plates and frames, and the detachment of sealing strips. These problems directly cause the sealing structure on the feed side to fail. When leakage occurs in the sealing structure, unfiltered raw slurry flows directly into the finished product silo, contaminating the already formed qualified filter cake and significantly increasing its moisture content. Utility Model Content

[0003] To address the above shortcomings, this utility model proposes a vertical filter press unloading device. Before the filter cake is unloaded, a baffle plate is used to prevent the slurry from flowing into the first receiving box, which helps to reduce the contamination of the finished product by the slurry leaking from the filter press, thereby stabilizing the moisture content of the filter cake within the qualified range.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A vertical filter press unloading device includes: a first vertical plate and a second vertical plate arranged opposite to each other, the first vertical plate being higher than the second vertical plate; a first receiving box being disposed between the two first vertical plates and the second vertical plate, the first receiving box being used to receive filter cake; a baffle plate being movably disposed on the first vertical plate in the vertical direction, the baffle plate being inclined relative to the first vertical plate; the baffle plate being connected to a lifting mechanism for driving its movement; when the baffle plate descends to abut against the second vertical plate, the baffle plate is used to receive and guide the slurry away from the first receiving box.

[0005] Furthermore, the lifting mechanism includes a rotating roller disposed on one side of the first upright plate, one end of the rotating roller is connected to a motor, a fixed pulley is disposed at the upper end of the first upright plate, and a lifting rope is connected to the upper end face of the baffle plate. The lifting rope is wound around the fixed pulley and the rotating roller in sequence, and the rotating roller winds up or unwinds the lifting rope to drive the baffle plate to rise and fall.

[0006] Furthermore, two guide rods are arranged parallel to each other on the other side of the first upright plate. The guide rods extend vertically, and the baffle plate is provided with two guide holes, each of which cooperates with the guide rod.

[0007] Furthermore, two mounting blocks are provided on the upper part of the first upright plate, and each mounting block is provided with a guide rod. One of the mounting blocks is provided with a first pressure sensor. Two receiving blocks are inclinedly provided on one side of the second upright plate. The baffle plate is located between the mounting block and the receiving block. The receiving block is provided with a second pressure sensor. The first pressure sensor, the second pressure sensor and the motor are electrically connected to a controller.

[0008] Furthermore, each of the guide rods is slidably provided with a mounting rod, the mounting rod being horizontally connected to the lower part of the baffle plate, and the mounting rod and the baffle plate forming an acute angle.

[0009] Furthermore, a guide plate is inclinedly provided at the upper end of the second vertical plate, and multiple filter holes are opened at the lower part of the guide plate. A second receiving box for receiving slurry is provided on one side of the second vertical plate. The filter holes are located above the second receiving box. When the baffle plate abuts against the second vertical plate, the baffle plate and the guide plate form a V-shaped structure.

[0010] Furthermore, a vertical plate extends upward from the upper end of the second vertical plate, and there is a gap between the vertical plate and the side wall of the second vertical plate. When the lower end of the baffle plate abuts against the vertical plate, the upper end surface of the baffle plate is in contact with the upper end surface of the vertical plate.

[0011] Furthermore, the baffle plate has two opposite side walls that extend upward to form a first side plate, and the guide plate has two opposite side walls that form a second side plate, with the first side plate located between the two second side plates.

[0012] Compared with existing technologies, this utility model has at least the following beneficial effects: 1. This utility model uses a baffle plate to prevent the slurry from flowing into the first receiving box before the filter cake is unloaded, which helps to reduce the contamination of the finished product by the slurry leaking from the filter press, thereby stabilizing the moisture content of the filter cake within the qualified range.

[0013] 2. This utility model uses a motor to drive the rotating roller to rotate, so that the lifting rope is wound or unwound on the rotating roller through a fixed pulley, thereby driving the baffle plate to rise and fall in the vertical direction.

[0014] 3. The present invention forms a V-shaped structure by means of a baffle plate and a guide plate, which is beneficial to guide the slurry leaking at different heights to fall into the second receiving box more effectively. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] See Figures 1 to 3 A vertical filter press unloading device includes: a first vertical plate 100 and a second vertical plate 110 arranged opposite to each other, the height of the first vertical plate 100 being greater than that of the second vertical plate 110, a first receiving box 200 being arranged between the two first vertical plates 100 and the second vertical plate 110, the first receiving box 200 being used to receive filter cake, a baffle plate 120 being movably arranged on the first vertical plate 100 in the vertical direction, the baffle plate 120 being inclined relative to the first vertical plate 100, the baffle plate 120 being connected to a lifting mechanism for driving its movement, when the baffle plate 120 descends to abut against the second vertical plate 110, the baffle plate 120 being used to receive and guide the slurry away from the side of the first receiving box 200.

[0022] In the vertical filter press unloading device with the above structure, during the filter cake formation process, the lifting mechanism drives the baffle plate 120 downward to abut against the second vertical plate 110. This allows the leaked slurry to fall off the baffle plate 120 and move away from the first receiving box 200, preventing the leaked slurry from falling directly into the first receiving box 200 and reducing contamination of the finished product by leaked slurry, thus stabilizing the moisture content of the filter cake within the acceptable range. Conversely, during the filter cake unloading process, the lifting mechanism drives the baffle plate 120 upward to move away from the second vertical plate 110, ensuring the filter cake falls smoothly into the first receiving box 200.

[0023] See Figures 1 to 3Furthermore, the lifting mechanism includes a rotating roller 300 located on one side of the first vertical plate 100. One end of the rotating roller 300 is connected to a motor 310. A fixed pulley 320 is provided at the upper end of the first vertical plate 100. A lifting rope 330 is connected to the upper end face of the baffle plate 120. The lifting rope 330 is wound around the fixed pulley 320 and the rotating roller 300 in sequence. The rotating roller 300 winds up or unwinds the lifting rope 330 to drive the baffle plate 120 to rise or fall. Specifically, when it is necessary to adjust the position of the baffle plate 120, the motor 310 drives the rotating roller 300 to rotate, so that the rotating roller 300 winds up or unwinds the lifting rope 330 to drive the baffle plate 120 to rise or fall in the vertical direction. It is understood that the lifting rope 330 is tangent to the outer periphery of the fixed pulley 320, and a guide wheel 340 is provided on one side of the first vertical plate 100. The lifting rope 330 adjusts its winding direction through the guide wheel 340 to better wind up or unwind onto the rotating roller 300. In some embodiments, the lifting mechanism can also replace the motor 310, the lead screw, and the slider. The slider is connected to the baffle plate 120, and the rotation of the lead screw drives the slider to reciprocate in the vertical direction, thereby driving the baffle plate 120 to rise and fall.

[0024] See Figures 1 to 3 Furthermore, two guide rods 130 are arranged parallel to each other on the other side of the first upright plate 100. The guide rods 130 extend vertically, and the baffle plate 120 is provided with two guide holes, each of which cooperates with the guide rod 130. This allows the guide rods 130 to guide and limit the movement of the baffle plate 120, enabling the baffle plate 120 to translate relative to the first upright plate 100, thus preventing the baffle plate 120 from shifting during movement. In some embodiments, a mounting base is slidably provided between the two guide rods 130. The baffle plate 120 is pivotally mounted on the mounting base, and a lifting rope 330 is connected to the side of the baffle plate 120 away from the guide rods 130. This allows the baffle plate 120 to flip towards one side of the first upright plate 100 under the action of the lifting rope 330, facilitating the folding of the baffle plate 120 so that the material falls more effectively into the first receiving box 200.

[0025] See Figures 1 to 3Furthermore, two mounting blocks 101 are provided on the upper part of the first vertical plate 100, and each mounting block 101 is provided with a guide rod 130. One of the mounting blocks 101 is provided with a first pressure sensor. Two receiving blocks 111 are inclinedly provided on one side of the second vertical plate 110. The baffle plate 120 is located between the mounting blocks 101 and the receiving blocks 111. The receiving blocks 111 are provided with a second pressure sensor. The first pressure sensor, the second pressure sensor, and the motor 310 are electrically connected to a controller. Specifically, the first pressure sensor and the second pressure sensor can generate a positioning signal for the baffle plate 120, causing the controller to control the motor 310 to stop operating. This facilitates the timely stopping of the baffle plate 120 after it moves to abut against the mounting block 101 or the second vertical plate 110, thereby preventing excessive movement of the baffle plate 120. It can be understood that the controller is associated with the operating program of the vertical filter press. When the vertical filter press starts its processing program, the controller controls the motor 310 to operate, lowering the baffle plate 120 to form a blockage, and controls the motor 310 to stop via the second pressure sensor. After the filter cake is pressed and enters the cake unloading stage, the controller controls the motor 310 to reverse to raise the baffle plate 120, and controls the motor 310 to stop via the first pressure sensor, thereby ensuring that the filter cake falls smoothly into the first receiving box 200.

[0026] See Figures 1 to 3 Furthermore, each guide rod 130 is slidably provided with an installation rod 121, which is horizontally connected to the lower part of the baffle plate 120. The installation rod 121 and the baffle plate 120 form an acute angle, thereby forming a triangular structure between the installation rod 121 and the baffle plate 120, which is beneficial to improving the structural strength of the baffle plate 120.

[0027] See Figures 1 to 3Furthermore, a guide plate 112 is inclinedly arranged at the upper end of the second vertical plate 110, and multiple filter holes 113 are opened at the lower part of the guide plate 112. A second receiving box 210 for receiving slurry is arranged on one side of the second vertical plate 110. The filter holes 113 are located above the second receiving box 210. When the baffle plate 120 abuts against the second vertical plate 110, the baffle plate 120 and the guide plate 112 form a V-shaped structure. Specifically, the upper end of the guide plate is connected to the bottom filter plate 400 of the vertical filter press, so that the guide plate 112 can receive the slurry leaking from the bottom filter plate 400 and fall into the second receiving box 210. The slurry leaking from the filter plate 400 above can fall through the baffle plate 120 to one side of the filter holes 113. Finally, the guide plate 112 and the baffle plate 120 form a V-shaped guiding slope to guide the leaked slurry to fall into the second receiving box 210. When the baffle plate 120 moves upward, the filter cake transported by the bottom filter plate 400 can fall into the first receiving box 200 through the guide plate 112, and the filter plates 400 transported by the upper filter plates 400 can fall directly into the first receiving box 200. In some embodiments, the second receiving box 210 is connected to the feeding system of the vertical filter press through a guide pipe, thereby circulating the leaked slurry to reduce the waste of raw materials.

[0028] See Figures 1 to 3 Furthermore, a vertical plate 114 extends upward from the upper end of the second vertical plate 110. There is a gap between the vertical plate 114 and the side wall of the second vertical plate 110. When the lower end of the baffle plate 120 abuts against the vertical plate 114, the upper end face of the baffle plate 120 is in contact with the upper end face of the vertical plate 114. This helps to improve the fit between the baffle plate 120 and the second vertical plate 110, thereby forming a continuous flow guide surface, which is conducive to the slurry flowing smoothly to one side of the filter hole 113.

[0029] See Figures 1 to 3 Furthermore, the baffle plate 120 has two opposite side walls that are provided with first side plates extending upwards, and the guide plate 112 has two opposite side walls that are provided with second side plates 115. The first side plates are located between the two second side plates 115, thereby using the first side plates to restrict the slurry from flowing out from both sides of the baffle plate 120 and using the second side plates 115 to restrict the slurry from flowing out from both sides of the guide plate 112, which is conducive to the leakage of slurry falling into the second receiving box 210 better.

[0030] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

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