Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of sulfur-containing wastewater treatment, and more specifically, relates to a desulfurization wastewater treatment device. BACKGROUND

[0002] Desulfurization wastewater is usually discharged by a desulfurization system during operation and contains heavy metals, impurities, and acid and other substances. The impurities contained in the wastewater mainly include suspended solids, supersaturated sulfites, sulfates, and heavy metals. Alkaline substances are usually added to the desulfurization wastewater in the desulfurization wastewater treatment device to cause precipitation inside the desulfurization wastewater, and then the precipitated desulfurization wastewater is filtered and discharged.

[0003] The existing Chinese utility model patent with the publication number CN217409870U, entitled "Desulfurization wastewater treatment device", drives the screw rod by the motor to make the C-shaped frame threadedly connected with the screw rod move the push plate on the surface of the filter plate through the guide rod, so that the push plate pushes the larger impurities adhering to the surface of the filter plate to the slag discharge opening opened on both sides of the box, avoiding the larger impurities from blocking the mesh holes of the filter plate and affecting the filtration efficiency of the filter plate on the wastewater. However, in the process of use, the larger impurities adhering to the surface of the filter plate are pushed and cleaned by the push plate, but it is difficult to dredge when the filter plate mesh holes are blocked by smaller impurities, which easily leads to the blockage of the filter plate, affecting the filtration efficiency and filtration effect of the desulfurization wastewater, and the use effect is poor.

[0049] The following embodiments will be used to provide a detailed description of a desulfurization wastewater treatment device according to this application.

[0050] In this embodiment, as Figs. 1 to 3 As shown, the desulfurization wastewater treatment device includes: a hollow housing 1;

[0051] The first conveying mechanism 101 is connected to the box 1 and is used to convey the wastewater to be desulfurized into the box 1.

[0052] The second conveying mechanism 102 is connected to the box 1 and is used to convey the reactant into the box 1;

[0053] The first filter plate 2 is horizontally set inside the box 1 and is provided with a first material passage hole 201 and several first through holes 202. The material passage hole is used to allow waste material to pass through during the desulfurization reaction.

[0054] The second filter plate 3 is slidably arranged at the lower side of the first filter plate 2, and is used for controlling the opening and closing of the first material passing hole 201 and the first through hole 202.

[0055] The driving mechanism 4 is connected with the second filter plate 3, and is used for driving the second filter plate 3 to move.

[0056] The filter cloth 5 is arranged at the upper side of the first filter plate 2, and the filter cloth 5 is correspondingly fixed at the first material passing hole 201, and the two ends of the filter cloth 5 are connected with the lifting mechanism 6.

[0057] The lifting mechanism 6 is arranged on the box body 1, and is used for driving the two ends of the filter cloth 5 to move up and down, and the filter cloth 5 is used for gathering waste materials to the first material passing hole 201 when the end of the filter cloth 5 rises.

[0058] The waste discharge assembly 7 is arranged at the lower side of the second filter plate 3 corresponding to the first material passing hole 201, and is used for collecting waste materials.

[0059] In the technical solution, the box body 1 is vertically arranged and hollowly arranged. The first conveying mechanism 101 and the second conveying mechanism 102 are both pipe structures with electromagnetic valves connected with pumps, and can convey the desulfurization wastewater and the reaction agent solution to the position where the filter cloth 5 is located in the box body 1.

[0060] The first filter plate 2 is horizontally fixed in the box body 1, and the first filter plate 2 is provided with five columns of first through holes 202 arranged in the front-rear direction, and a long strip-shaped first material passing hole 201 extending in the front-rear direction is arranged between the second column and the third column of the first through holes 202, and the first material passing hole 201 is located at the position in the left-right direction of the first filter plate 2. The second filter plate 3 is provided with three columns of second through holes, and the three columns of second through holes of the second filter plate 3 are respectively aligned with the first column, the fourth column and the fifth column of the first through holes 202 of the first filter plate 2, at this time, the position of the second column of the first through holes 202 of the first filter plate 2 is not provided with any hole, and at this time, the position of the third column of the first through holes 202 of the first filter plate 2 is provided with a second material passing hole which is the same as the shape of the first material passing hole 201.

[0061] In the current position, the first column, the third column, the fourth column and the fifth column of the through holes on the first filter plate 2 can seep water downward through the hole structure on the second filter plate 3; moving the second filter plate 3 from the current position to the left by half the interval of two columns of the first through holes 202 can make each of the first through holes 202 on the first filter plate 2 be in a closed state, but make the first material passing hole 201 and the second material passing hole be aligned, so that the precipitate on the filter plate can move downward through the two material passing holes; if the second filter plate 3 is moved to the right from the aforementioned current position, the first material passing hole 201 and the first through hole 202 on the first filter plate 2 can be blocked, at this time, the wastewater on the first filter plate 2 can be in a relatively static state to react with the reaction agent.

[0062] It is worth mentioning that for the movement of the aforementioned second filter plate 3, the first through hole 202 in the second column on the first filter plate 2 is always in a closed state, so the first through hole 202 at the position of the second column can not be processed when the first filter plate 2 is actually processed.

[0063] The second filter plate 3 extends guide portions to the left and right at both ends, and the box body 1 is correspondingly provided with guide holes for the guide portions to pass through. A rack is arranged on one of the guide portions, and the driving mechanism 4 is provided with a gear that meshes with the rack. The motor of the driving mechanism 4 drives the gear to rotate forward and backward to adjust the left and right positions of the second filter plate 3.

[0064] The middle of the filter cloth 5 is fixed at the first material passing hole 201, and the filter cloth 5 is provided with a hard stop edge 501 corresponding to the positions of the left and right ends of the first filter plate 2 to maintain the shape of the filter cloth 5. In some technical solutions, two end-type hard stop edges 501 can also be arranged on the front and back sides of the filter cloth 5 to maintain the shapes of the front and back sides of the filter cloth 5, so that when the filter plate is placed on the first filter plate 2 again after being acted on by the lifting mechanism 6, it can still cover the upper side of the first filter plate 2.

[0065] The filter cloth 5 is provided with a relief hole corresponding to the first material passing hole 201 to allow the precipitate after the reaction to pass through. Specifically, the filter cloth 5 is provided with a strip-shaped hole equal in size to the first material passing hole 201, and the filter cloth 5 is provided with a fixing strip corresponding to the first material passing hole 201 to fix and shape the relief hole.

[0066] The lifting mechanism 6 is arranged outside the box body 1 and connected to the left and right ends of the filter cloth 5 to drive the portions of the filter cloth 5 between the left and right sides of the relief hole to move up and down, and to promote the aggregation of the precipitate generated by the reaction to the first material passing hole 201 during the upward movement.

[0067] The waste discharge assembly 7 is arranged on the lower side of the second filter plate 3 and correspondingly on the lower side of the first material passing hole 201. After the precipitate generated after the reaction is aggregated to the first material passing hole 201 by the filter cloth 5, it moves to the waste discharge assembly 7 through the first material passing hole 201 and the second material passing hole.

[0068] In other technical solutions, the hard stop edge 501 near the corners of the left and right sides of the filter cloth 5 is connected to a counterweight 502 through a flexible rope, which facilitates the resetting of the filter cloth 5 after the filter cloth 5 is acted on by the lifting mechanism 6.

[0069] In this embodiment, the filter cloth 5, the lifting mechanism 6, the first filter plate 2, and the waste discharge assembly 7 are all arranged symmetrically to the left and right as two, and the second filter plate 3 extends to the lower side of the two first filter plates 2.

[0070] In the technical solution, the filter cloth 5, the lifting mechanism 6, the first filter plate 2 and the waste discharge assembly 7 are symmetrically arranged on the left and right sides as two, the first conveying mechanism 101 and the second conveying mechanism 102 can respectively convey the desulfurization wastewater and the reaction agent to the positions where the two filter cloths 5 are located, and the second filter plate 3 extends from the left to the lower side of the two filter plates.

[0071] In order to realize the synchronous or step-by-step opening and closing of the two first filter plates 2, the positions of the second through holes and the second material passing holes on the second filter plate 3 corresponding to the position of the right first filter plate 2 need to be adjusted. For example, the second material passing holes on the right part of the second filter plate 3 are arranged on the lower side of the second column of first through holes 202 of the right first filter plate 2 in the direction from right to left.

[0072] In the embodiment, the lifting mechanism 6 comprises:

[0073] The first fixed rod 601 is fixed at the left end of the filter cloth 5;

[0074] The second fixed rod 602 is fixed at the right end of the filter cloth 5;

[0075] The front and rear walls of the box body 1 are provided with the first guide groove 103 and the second guide groove 104, the first guide groove 103 and the second guide groove 104 are symmetrically arranged on the left and right sides, and the first guide groove 103 and the second guide groove 104 gradually approach in the upward direction;

[0076] The two guide rods 603 are provided with the third guide groove, and the two guide rods 603 are symmetrically arranged on the front and rear sides of the box body 1 and are slidably arranged outside the box body 1, the two ends of the first fixed rod 601 are clamped in the third guide grooves of the two guide rods 603 through the two first guide grooves 103, and the two ends of the second fixed rod 602 are clamped in the third guide grooves of the two guide rods 603 through the two second guide grooves 104;

[0077] The lifting mechanism 604 is connected with the guide rod 603 and is used to drive the guide rod 603 to move up and down.

[0078] In the technical solution, the first fixed rod 601 and the second fixed rod 602 are symmetrically arranged at both ends of the filter cloth 5, the front and rear ends of the first fixed rod 601 and the second fixed rod 602 extend to the front and rear sides of the box body 1, and the guide rod 603 is closed and connected with the first fixed rod 601 and the second fixed rod 602. The first guide groove 103 is located on the left side and extends in the direction from the lower left to the upper right. The second guide groove 104 is located on the right side relative to the first guide groove 103 and extends in the direction from the lower right to the upper left. The lifting mechanism 604 is a screw rod and sliding block mechanism and is fixedly connected with the guide rod 603 at the rear side. With the driving of the driving mechanism 4, the fixed rod can be driven to move upward. Under the guidance of the first guide groove 103 and the second guide groove 104, the part of the filter cloth 5 located on both sides of the first material passing hole 201 is gradually moved upward, the filter cloth 5 on both sides of the first material passing hole 201 is inclined, and then the precipitate generated in the upper side reaction is gathered to the first material passing hole 201.

[0079] In use, the second filter plate 3 is first moved to a state in which the first material passing hole 201 and the first through hole 202 are closed. After the wastewater reacts with the reagent for a certain period of time, the second filter plate 3 is moved to a state in which the first through hole 202 is communicated with the second through hole. The wastewater on the filter cloth 5 is discharged downward, and the precipitate is filtered by the filter cloth 5. Finally, the position of the second filter plate 3 is switched to a state in which the second material passing hole is aligned with the first material passing hole 201. The lifting mechanism 6 is opened, the precipitate moves downward to the waste discharge assembly 7 through the two material passing holes, and the separation of the wastewater and the precipitate is realized.

[0080] In some technical solutions, the same lifting mechanism 6 is provided with two lifting mechanisms 604, which are fixedly connected with two guide rods 603, respectively. The influence of the deformation of the filter cloth 5 on the upward and downward movement can be reduced.

[0081] In the embodiment, the stirring mechanism 8 is correspondingly arranged on the upper side of the first material passing hole 201.

[0082] In the technical solution, the stirring mechanism 8 is a few-shaped rod driven by a motor and is correspondingly arranged on the side wall of the box body 1 on the upper side of the first material passing hole 201. The stirring mechanism 8 can stir during the reaction and can provide a certain driving force to promote the movement of the precipitate to the material passing hole when the precipitate is discharged downward. Specifically, the stirring mechanism 8 is symmetrically arranged as two.

[0083] In the embodiment, the box body 1 is provided with a liquid discharge hole 105, and the height of the liquid discharge hole 105 is lower than the height of the second filter plate 3.
