[0004] At present, in order to improve the filtration efficiency during the wastewater pretreatment process, a multi-stage filtration method is usually used to filter the wastewater. However, as the filtration continues, the filtered substances will adhere to the filter plate and gradually reduce the filtration efficiency.

If the filter plate is replaced to ensure the filtration effect, although the downtime can be shortened to a certain extent, the capacity is limited and multiple filter plates need to be replaced. Therefore, there is an urgent need for a technology that can quickly clean the filtered materials on the filter plate, ensure the filtration efficiency, and enable the filtration system to continuously and efficiently and stably filter wastewater, so as to improve the existing wastewater pretreatment capabilities.

DETAILED DESCRIPTION

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0028] See also Figure 1 and Figure 2 , an acid regeneration equipment wastewater high efficiency filtration device, comprising a box body 1 with a plurality of filter plates 2 vertically installed inside; Figure 1 As shown, the filter plates 2 are distributed from left to right and divide the box body 1 into several filter areas. The apertures of the filter holes on the filter plates 2 gradually decrease from right to left, forming a multi-stage filtration system. An outlet is provided on the lower left side of the box body 1, and an inlet is provided on the upper right side. The liquid enters the box body 1 from the inlet, and then is filtered by the filter plates 2 in sequence, and finally discharged from the outlet. The multi-stage filtration system can effectively reduce the load of single-stage filtration, delay clogging, and is conducive to improving the efficiency of continuous filtration.

[0029] See also Figure 1 , Figure 2 and Figure 6 A cleaning head 5 is vertically slidably arranged on the top of the box body 1, and a head collection port 3 is opened at the bottom. A collecting chamber 6 is sealed and connected below the collection port 3. A blocking head 7 is arranged in the collection chamber 6. The blocking head 7 blocks the collection port 3. In the filtering state, the cleaning head 5 moves from top to bottom, and dynamically divides the filtering area into two independent upper and lower areas. With the movement of the cleaning head 5, the filtered materials on the filter plate 2 and the inner wall of the box body 1 and the filtered materials in the area below the cleaning head 5 are gathered to the collection port 3 as the cleaning head 5 moves downward. This process In the process, the area above the cleaning head 5 maintains an efficient filtering state, and the area below the cleaning head 5 is in a state of continuous pressure filtration. When the cleaning head 5 is about to move to the bottom of the box body 1, the blocking head 7 moves down to open the aggregate opening 3, so that the gathered filtered matter enters the collecting chamber 6. Without stopping the filtering work, the filtered matter attached to the filter plate 2 and the inner wall of the box body 1 is cleaned in time, and the cleaned filtered matter and the filtered matter in the area below the cleaning head 5 are discharged from the filtering area in time, thereby improving the efficiency of continuous operation of the multi-stage filtering system.

[0030] See also Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The collecting chamber 6 includes a temporary retention part 61 and a water removal collecting part 62 which are distributed from top to bottom and are interconnected. The temporary retention part 61 is sealed and connected to the collecting port 3. The right side of the water removal collecting part 62 is provided with a discharge port 63, and the front and rear sides are provided with liquid outlets 64. The plugging head 7 is vertically slidably installed in the collecting chamber 6, and the plugging head 7 has a first working position, a second working position and a third working position; Figure 5As shown, at this time, the plugging head 7 is located at the first working position to plug the collection opening 3, so that the collection opening 3 is in a closed state; when the cleaning head 5 moves down and is about to reach the bottom of the box body 1, the plugging head 7 moves down to the second working position. During this process, the plugging head 7 first blocks the water removal collection part 62 to disconnect it from the temporary retention part 61 (as shown in FIG. Figure 6 As shown in FIG. 1 ), at this time, the plugging head 7 is in a state of being tightly connected to the water removal and collection part 62 without being disconnected from the material collection port 3; then the plugging head 7 continues to move downward to open the material collection port 3, so that the accumulated retentate enters the temporary retention part 61 from the material collection port 3 (as shown in FIG. 1 ). Figure 7 Afterwards, the plugging head 7 can be moved upward to reset to the first working position, the water removal collection part 62 is connected to the temporary retention part 61, and the filtered material in the temporary retention part 61 enters the water removal collection part 62. The plugging head 7 can also continue to move downward to the third working position (as shown in FIG. Figure 8 As shown in the figure, during this process, the plugging head 7 first compresses the filtrate in the water removal collection part 62, so that the water in the filtrate is discharged from the liquid outlet 64, and then the discharge port 63 is opened to discharge the filtrate after compression and water removal from the discharge port 63, so that the liquid is separated from the filtrate; on the one hand, the quality of filtration is improved, and on the other hand, the coordination of the cleaning head 5 and the plugging head 7 and the closed state of the plugging head 7 and the collection port 3 are compensated, so as to avoid that during the process of the cleaning head 5 and the plugging head 7 cooperating to discharge the material, excessive liquid is discharged from the filtration area along with the filtrate, or the airtightness of the collection port 3 is reduced in the closed state, resulting in the outflow of liquid in the filtration area, causing the filtrate discharged from the filtration area to have too much water content, thereby fully improving the filtration efficiency and quality of the multi-stage filtration system, and enabling it to maintain a high-efficiency filtration state continuously and stably.

[0031] See also Figure 2 and Figure 3 The cleaning head 5 includes a switch opening 4, a passive part 51 and an active part 52. The passive part 51 is a scraper of a rectangular structure, and its front, rear, left and right end faces are closely attached to the inner wall of the box body 1 and the filter plate 2. The number of switch openings 4 is several and evenly distributed on the passive part 51 from front to back. The active part 52 is located above the passive part 51 and a plurality of closing blocks 53 are fixedly installed on the bottom surface of the active part 52. The closing blocks 53 correspond to the switch openings 4 one by one and are used to fill and block the switch openings 4. A limited position connector 54 is arranged between the active part 52 and the passive part 51; Figure 3As shown, the limit connecting member 54 is a connecting column with a limit end at the top, and the limit end is located above the active part 52. The connecting column is fixedly connected to the passive part 51 and is slidably connected to the active part 52 up and down; during the downward movement of the active part 52, it first moves down along the connecting column to the closing block 53 and is inserted into the corresponding on-off opening 4, so that the on-off opening 4 is in a closed state. During this process, the friction between the passive part 51 and the filter plate 2 and the inner wall of the box body 1 can effectively inhibit the movement of the passive part 51, so that it does not move with the downward movement of the active part 52. After the on-off opening 4 is closed, the active part 52 abuts against the passive part 51, and the active part 52 continues to move downward and overcomes the friction force that inhibits the movement of the passive part 51, pushing the passive part 51 to move downward and scrape off the retained matter on the filter plate 2 and the inner wall of the box body 1, so that the retained matter moves to The active part 52 first moves up along the connecting column to the state where the closing block 53 is separated from the switch port 4. Similarly, in this process, the passive part 51 does not move with the upward movement of the active part 52 under the suppression of friction. When the active part 52 hits the lower side of the limit end and continues to move up, the active part 52 will drive the limit connecting piece 54 to move up synchronously, and the limit connecting piece 54 will drive the passive part 51 to move up synchronously. At this time, the liquid in the upper area of ​​the cleaning head 5 enters the lower area of ​​the cleaning head 5 through the switch port 4; wherein, the limit connecting pieces 54 are multiple and evenly divided into two rows, the two rows of limit connecting pieces 54 are symmetrically distributed on the left and right, and the limit connecting pieces 54 in each row are distributed from front to back, so that the active part 52 can move up and down stably based on the passive part 51.

[0032] See also Figure 1 , Figure 2 , Figure 4 and Figure 5 A filter screen 9 is provided at the connection between the liquid outlet 64 and the water removal collection part 62, and a liquid storage tank 12 is provided at the port of the liquid outlet 64 away from the filter screen 9. The surface of the filter screen 9 will be scraped and cleaned in the process of the sealing head 7 opening the discharge port 63, which is beneficial to ensure the stability of the filtering state of the filter screen 9 to a certain extent, and thus ensure the quality of the pressure filtration and water removal.

[0033] See also Figure 1 , Figure 2 and Figure 3A driving mechanism 8 is installed on the box body 1, and the driving mechanism 8 includes a first driving unit for controlling the cleaning head 5 to move up and down and a second driving unit for controlling the blocking head 7 to move up and down. The first driving unit and the second driving unit both include a moving seat 81 and a plurality of connecting rods 82, wherein the first driving unit also includes a first mounting seat 83, and the corresponding moving seat 81 is vertically slidably mounted on the first mounting seat 83, and the corresponding connecting rod 82 is fixedly connected between the moving seat 81 and the active part 52, and the second driving unit also includes a second mounting seat 84, and the corresponding moving seat 81 is vertically slidably mounted on the second mounting seat 8 4, the corresponding connecting rod 82 is fixedly connected between the moving seat 81 and the plugging head 7, and the first mounting seat 83 and the second mounting seat 84 are both equipped with driving cylinders, and the corresponding moving seat 81 is controlled to reciprocate in the vertical direction by the cylinder, and the connecting rod 82 can be used to control the multiple cleaning heads 5 and the multiple plugging heads 7 to move up and down accordingly, wherein the first mounting seat 83 and the second mounting seat 84 are mainly used for slidingly mounting the corresponding moving seat 81, and the specific structures and sizes of the two may be different, and the first mounting seat 83 and the second mounting seat 84 are respectively mounted on the top and bottom of the box body 1.

[0034] See also Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 A vertically sliding opening and closing member 10 is provided at the discharge port 63. The opening and closing member 10 is plate-shaped and is inserted into the discharge port 63 by sliding from bottom to top. A linkage control assembly 11 is provided between the opening and closing member 10 and the plugging head 7. The linkage control assembly 11 includes a limit head 111 and an interval limit member 112. The limit head 111 is fixedly connected to the opening and closing member 10, and the interval limit member 112 is fixedly connected to the corresponding connecting rod 82. The second mounting seat 84 is provided with an avoidance groove for avoiding the opening and closing member 10 and the interval limit member 112; Figure 4As shown, the interval limiting member 112 has a C-shaped structure; the connecting rod 82 moves the plugging head 7 downward under the control of the moving seat 81 to compress the filter material in the water removal and collection part 62. When the upper horizontal section of the interval limiting member 112 limits the limiting head 111 from above, as the plugging head 7 moves downward, the upper horizontal section of the interval limiting member 112 pushes the opening and closing member 10 to move downward accordingly, gradually opening the discharge port 63. During the process of the plugging head 7 moving upward and resetting, when the lower horizontal section of the interval limiting member 112 limits the limiting head 111 from below, the opening and closing member 10 synchronously moves upward and resets under the push of the lower horizontal section of the interval limiting member 112, and gradually closes the discharge port 63. A storage tank 13 is arranged below the discharge port 63, and the filter material enters the storage tank 13 from the discharge port 63. During the process when the horizontal section of the interval limiting member 112 does not contact the opening and closing member 10, the opening and closing member 10 remains in the current position state under the action of friction force.

[0035] Referring to Figure 2 and Figure 3 , an arc-shaped concave area is provided on the top surface of the passive part 51, and an arc-shaped convex area that fits with the arc-shaped concave area is provided at the bottom of the active part 52. The on-off port 4 is opened at the arc-shaped concave area; as Figure 3 shown in the lower view in

[0036] Referring to Figure 2 , Figure 4 , Figure 5 and Figure 6 , the plugging head 7 includes an upper plugging part 71 with a convex arc surface at the top and a lower plugging part 73 provided with an inclined limiting surface 72. The bottom of the lower plugging part 73 is inclined (as Figure 5 shown), and correspondingly, the bottom of the water removal and collection part 62 is also inclined. When the aggregate port 3 is in a closed state, the connection between the temporary retention part 61 and the aggregate port 3 is in close contact with the upper plugging part 71. At this time, the upper plugging part 71 plugs the aggregate port 3, and the inclined limiting surface 72 and the inner wall of the temporary retention part 61 form a wedge-shaped seal, further improving the sealing performance of the aggregate port 3. Among them, the temporary retention part 61 and the plugging head 7 cooperate to form two retention areas on both sides of the plugging head 7. The bottom of the retention area is inclined, facilitating the filter material in the temporary retention part 61 to slide fully along the inclined surface at the bottom into the water removal and collection part 62.
