Description

Technical Field

[0001] The present invention relates to the technical field of filtering equipment, and particularly to a high-efficiency filtering equipment for wastewater of an acid regeneration equipment. Background Art

[0002] The acid regeneration equipment is mainly used for treating wastewater containing acidic substances to make the wastewater meet the discharge standard or the reuse standard, and is usually applied to industries such as metal processing, electroplating, and chemical industry.

[0003] The filtration of wastewater, as the core link to ensure the stable operation of the acid regeneration equipment and environmental protection, usually includes a pretreatment stage and a deep treatment stage. Among them, the pretreatment stage is mainly used to remove larger particulate matters, suspended matters, etc., to provide stable water quality conditions for subsequent treatment and avoid damage to the equipment.

[0004] At present, in the process of wastewater pretreatment, in order to improve the filtration efficiency, a multi-stage filtration method is usually adopted to filter the wastewater. However, as the filtration continues, the filtered substances will adhere to the filter plate and gradually reduce the filtration efficiency. At this time, if the filter plate is cleaned by means of shutdown cleaning, the overall equipment operation time will be shortened and the continuous filtration efficiency will be reduced. And if the filter plate is replaced to ensure the filtration effect, although the shutdown time can be shortened to a certain extent, the ability is limited and multiple filter plates need to be replaced. Therefore, there is an urgent need for a technology that can quickly clean the filter substances on the filter plate, ensure the filtration efficiency, and enable the filtration system to continuously, efficiently and stably filter wastewater, so as to improve the existing wastewater pretreatment ability.

[0027] To make the above - mentioned objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand 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 departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific implementation manners disclosed below.

[0028] Please refer to Figure 1 and Figure 2 , a high-efficiency filtration device for the wastewater of an acid regeneration device, comprising a box body 1 with several filter plates 2 vertically installed inside; as Figure 1 shown, the filter plates 2 are distributed in sequence from left to right and divide the box body 1 into several filtration zones. The pore diameters of the filtration holes on several filter plates 2 gradually decrease from right to left, forming a multi-stage filtration system; an outlet is arranged at the lower left side of the box body 1, and an inlet is arranged at the upper right side. Liquid enters the box body 1 from the inlet, then passes through the filtration of the filter plates 2 in sequence, and finally is discharged from the outlet. The multi-stage filtration system can effectively reduce the load of single-stage filtration, delay clogging, and is beneficial to improving the efficiency of continuous filtration.

[0029] Refer to Figure 1 , Figure 2 and Figure 6 , a cleaning head 5 is vertically slidably arranged at the top of the box body 1, and a head aggregate port 3 is opened at the bottom. A collection chamber 6 is hermetically communicated below the aggregate port 3. A plugging head 7 is arranged in the collection chamber 6, and the plugging head 7 plugs the aggregate port 3. In the filtration state, the cleaning head 5 moves from top to bottom, dynamically dividing the filtration zone into two independent upper and lower regions. As the cleaning head 5 moves, the filter substances on the filter plates 2 and the inner side wall of the box body 1 and the filter substances in the area below the cleaning head 5 all move down with the cleaning head 5 and gather at the aggregate port 3. During this process, the area above the cleaning head 5 maintains an efficient filtration state, and the area below the cleaning head 5 is in a continuous pressure filtration state. When the cleaning head 5 is about to move to the bottom of the box body 1, the plugging head 7 moves down to open the aggregate port 3, so that the gathered filter substances enter the collection chamber 6. Without stopping the filtration work, the filter substances attached to the filter plates 2 and the inner wall of the box body 1 are cleaned in time, and the cleaned filter substances and the filter substances in the area below the cleaning head 5 are discharged from the filtration zone in time, improving the efficiency of the continuous operation of the multi-stage filtration system.

[0030] Refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 , the collection chamber 6 includes a temporary retention part 61 and a water removal and collection part 62 that are distributed from top to bottom and are interconnected. The temporary retention part 61 is hermetically communicated with the aggregate port 3. A discharge port 63 is arranged on the right side of the water removal and collection part 62, and liquid discharge ports 64 are arranged on the front side and the rear side. The plugging head 7 is vertically slidably installed in the collection chamber 6, and the plugging head 7 has a first working position, a second working position, and a third working position; as Figure 5As shown, at this time, the plugging head 7 is located at the first working position to plug the aggregate inlet 3, so that the aggregate inlet 3 is in a closed state; when the cleaning head 5 moves downwards and is about to reach the bottom of the box body 1, the plugging head 7 moves downwards into the second working position. During this process, the plugging head 7 first plugs the water removal and collection part 62 to disconnect it from the temporary retention part 61 (as shown in Figure 6 ). At this time, on the basis that the plugging head 7 is not disconnected from the aggregate inlet 3, it is in a tightly connected state with the water removal and collection part 62; then the plugging head 7 continues to move downwards to open the aggregate inlet 3, so that the accumulated retention substances enter the temporary retention part 61 from the aggregate inlet 3 (as shown in Figure 7 ). After that, the plugging head 7 can move upwards to reset to the first working position, the water removal and collection part 62 is communicated with the temporary retention part 61, and the filter in the temporary retention part 61 enters the water removal and collection part 62. The plugging head 7 can also continue to move downwards into the third working position (as shown in Figure 8 ). During this process, the plugging head 7 first compresses the filter in the water removal and collection part 62, so that the water in the filter is discharged from the liquid outlet 64, and then the discharge port 63 is opened, so that the filter after compression and water removal is discharged from the discharge port 63, separating the liquid from the filter; on the one hand, it improves the filtering quality, and on the other hand, it compensates for the cooperative work of the cleaning head 5 and the plugging head 7 and the closed state of the plugging head 7 and the aggregate inlet 3, avoiding the situation that excessive liquid flows out of the filtering area along with the filter during the process of the cleaning head 5 and the plugging head 7 cooperating to discharge materials, or the liquid in the filtering area flows out due to the reduced airtightness of the aggregate inlet 3 in the closed state, resulting in the excessive water content of the filter discharged from the filtering area, fully improving the filtering efficiency and quality of the multi-stage filtering system and keeping it in a highly efficient filtering state continuously and stably.

[0031] Refer to Figure 2 and Figure 3 , the cleaning head 5 includes a switching port 4, a passive part 51 and an active part 52. The passive part 51 is a scraper with 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 switching ports 4 is several and they are evenly distributed on the passive part 51 from front to back. The active part 52 is located above the passive part 51, and several closing blocks 53 are fixedly installed on the bottom surface of the active part 52. The closing blocks 53 correspond to the switching ports 4 one by one and are used to fill and plug the switching ports 4. A limiting connecting piece 54 is arranged between the active part 52 and the passive part 51; as shown in Figure 3As shown, the limit connecting member 54 is a connecting column with a limit end at the top. 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 downward along the connecting column until the closing block 53 inserts into the corresponding on-off port 4, making the on-off port 4 in a closed state. During this process, the frictional force between the passive part 51, 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 along with the downward movement of the active part 52. After the on-off port 4 is closed, the active part 52 abuts against the passive part 51. The active part 52 continues to move downward and overcomes the frictional force that inhibits the movement of the passive part 51, pushing the passive part 51 to move downward along with it and scraping the deposits on the inner walls of the filter plate 2 and the box body 1, causing the deposits to gather downward. During the upward reset process of the active part 52, the active part 52 first moves upward along the connecting column to the state where the closing block 53 is separated from the on-off port 4. Similarly, during this process, the passive part 51 is inhibited by the frictional force and does not move along with the upward movement of the active part 52. When the active part 52 abuts against the lower side of the limit end and continues to move upward, the active part 52 will drive the limit connecting member 54 to move upward synchronously, and the limit connecting member 54 will drive the passive part 51 to move upward synchronously. At this time, the liquid in the area above the cleaning head 5 enters the area below the cleaning head 5 through the on-off port 4. Among them, the number of limit connecting members 54 is several and they are evenly divided into two columns. The two columns of limit connecting members 54 are symmetrically distributed left and right, and the limit connecting members 54 in each column 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] Refer to 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. During the process of opening the discharge port 63 by the plugging head 7, the surface of the filter screen 9 will be scraped and cleaned, which is beneficial to ensuring the stability of the filtering state of the filter screen 9 to a certain extent, and thus ensuring the quality of pressure filtration and water removal.

[0033] Refer to Figure 1 , Figure 2 and Figure 3, a driving mechanism 8 is installed on the box body 1. The driving mechanism 8 includes a first driving unit for controlling the up and down movement of the cleaning head 5 and a second driving unit for controlling the up and down movement of the plugging head 7. Both the first driving unit and the second driving unit include a moving seat 81 and a plurality of connecting rods 82. Among them, the first driving unit further includes a first mounting seat 83. The corresponding moving seat 81 is vertically slidably installed 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. The second driving unit further includes a second mounting seat 84. The corresponding moving seat 81 is vertically slidably installed on the second mounting seat 84, and the corresponding connecting rod 82 is fixedly connected between the moving seat 81 and the plugging head 7. Driving cylinders are installed on both the first mounting seat 83 and the second mounting seat 84. By controlling the corresponding moving seat 81 to reciprocate in the vertical direction through the cylinders, the plurality of cleaning heads 5 and the plurality of plugging heads 7 can be controlled to perform corresponding up and down movement work through the connecting rods 82. Among them, the first mounting seat 83 and the second mounting seat 84 are mainly used for slidably installing the corresponding moving seats 81, and their specific structures and sizes can be different. The first mounting seat 83 and the second mounting seat 84 are respectively installed on the top and bottom of the box body 1.

[0034] Refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 , a vertically slidable opening and closing member 10 is provided at the discharge port 63. The opening and closing member 10 is plate-shaped and is slidably inserted into the discharge port 63 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 limiting member 112. The limit head 111 is fixedly connected to the opening and closing member 10, and the interval limiting member 112 is fixedly connected to the corresponding connecting rod 82. The second mounting seat 84 is provided with an avoidance through groove for avoiding the opening and closing member 10 and the interval limiting member 112; as Figure 4As shown, the interval limit member 112 is of a U-shaped structure; the connecting rod 82, under the control of the moving seat 81, moves the plugging head 7 downward to compress the filter material in the water removal and collection part 62. When the upper horizontal section of the interval limit member 112 limits the limit head 111 from above, as the plugging head 7 moves downward, the upper horizontal section of the interval limit 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 limit member 112 limits the limit 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 limit member 112, and gradually closes the discharge port 63. A storage tank 13 is provided 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 limit 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.

[0035] Refer 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] Refer 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 fully slide into the water removal and collection part 62 along the inclined surface at the bottom.

[0037] In the embodiments of the present invention, unless otherwise clearly defined and limited, the first feature being "on" or "under" the second feature may mean that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "beneath" and "underneath" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply indicates that the horizontal height of the first feature is less than that of the second feature.

[0038] In the description of the present invention, it should also be noted that, unless otherwise clearly defined and limited, the terms "arranged", "connected", "installed" and "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, an integral connection or a sliding connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
