DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Embodiment 1

[0041] See also Figure 1-Figure 10 , a waste liquid treatment mechanism, such as Figure 1-Figure 4 As shown, it includes a filter 4 arranged at the bottom of the processing box 1, and a derivation pipe 5 connected to the filter 4 is arranged on the processing box 1; it can be understood that the filter 4 is the prior art, and the waste liquid in the processing box 1 is filtered by the filter 4 and then discharged through the derivation pipe 5. A first filtering mechanism 2 is provided on the processing box 1; the first filtering mechanism 2 includes a filter screen 21, a reeling mechanism 22, a connecting shaft 23 and a first driving mechanism 24; wherein, the filter screen 21 is provided in the processing box 1; it can be understood that the filter screen 21 is a flexible structure; the reeling mechanism 22 is installed on the processing box 1, and is used to reel in or unreel the filter screen 21; the connecting shaft 23 is provided at the free end of the filter screen 21 (i.e., the end of the filter screen 21 that deviates from the reeling mechanism 22); the first driving mechanism 24 is installed on the processing box 1, and is used to control the connecting shaft 23 to move upward or reset downward from the bottom of the processing box 1 along the inner wall of the processing box 1; when the connecting shaft 23 moves upward from the bottom of the processing box 1 along the inner wall of the processing box 1, the filter screen 21 is used to salvage the flocculants in the processing box 1.

[0042] It should be noted that, in the process of waste liquid treatment, in order to increase the reaction speed and optimize the stirring and mixing effect, specifically, the first drive mechanism 24 controls the movement of the connecting shaft 23 in the treatment box 1, and at the same time, the winding mechanism 22 is responsible for the winding and unwinding operations of the filter 21. This design ensures that when the connecting shaft 23 moves according to the instruction of the first drive mechanism 24, the filter 21 can always remain in a taut state and move stably in the treatment box 1. By adjusting the speed at which the first drive mechanism 24 drives the connecting shaft 23, the movement rate of the filter 21 can be accurately controlled to achieve an ideal stirring effect. This method not only improves the waste liquid treatment efficiency, but also avoids the problem of precipitated solid impurities being broken due to excessive stirring, thereby ensuring the effect of the subsequent filtration step.

[0043] See also Figure 1-Figure 4 In an optional embodiment, it can be understood that the present application does not limit the specific structure and installation method of the winding mechanism 22. The following only provides a feasible technical solution for reference: the winding mechanism 22 includes a first motor 221 and a winding shaft 222; the first motor 221 is installed in the processing box 1, and the winding shaft 222 is coaxially connected to the output end of the first motor 221.

[0044] It should be noted that after the waste liquid treatment reaction is completed, in order to effectively separate impurities and accelerate the filtering process, the first driving mechanism 24 drives the connecting shaft 23 to move, and the reeling mechanism 22 ensures that the filter screen 21 remains taut during the entire process. As the connecting shaft 23 moves upward from the bottom of the treatment box 1 according to a predetermined path, the taut filter screen 21 rises accordingly, effectively taking out the impurities in the waste liquid. This process not only realizes the salvage of impurities in the waste liquid, but also facilitates the subsequent rapid filtering and separation operations, thereby improving the efficiency and effect of the entire waste liquid treatment process.

[0045] See also Figure 1-Figure 4 In an optional embodiment, a transmission mechanism 223 is arranged between the output end of the first motor 221 and the winding shaft 222; it can be understood that the present application does not limit the specific structure and installation method of the transmission mechanism 223, and only a feasible technical solution is provided below for reference: the transmission mechanism 223 includes a belt 2232 and two rotating wheels 2231; the two rotating wheels 2231 are coaxially fixed to the output end of the first motor 221 and the winding shaft 222 respectively; the belt 2232 is tensioned on the two rotating wheels 2231.

[0046] It should be noted that one of the rotating wheels 2231 is driven to rotate by the first motor 221, and under the transmission action of the belt 2232, the other rotating wheel 2231 rotates accordingly, thereby driving the winding shaft 222 to rotate. In this way, the winding or unwinding process of the filter 21 can be accurately controlled. Specifically, when the first motor 221 is started, the power it generates is transmitted to the rotating wheel 2231 connected thereto, and with the help of the connection of the belt 2232, the power is transmitted to the second rotating wheel 2231, and finally the winding shaft 222 rotates.

[0047] See also Figure 1-Figure 4 In an optional embodiment, the first driving mechanism 24 includes a second motor 242, a pair of slide rails 241 and a rotating rod 243; the second motor 242 is installed on the processing box 1, the rotating rod 243 is fixed to the output end of the second motor 242, and the rotating rod 243 is provided with a first slide groove 244 (such as Fig.10 As shown), the end of the connecting shaft 23 is slidably connected to the first slide groove 244; a pair of slide rails 241 are arranged on the inner walls of both sides of the processing box 1, and the two ends of the connecting shaft 23 are slidably connected to the pair of slide rails 241 respectively.

[0048] It should be noted that when the first driving mechanism 24 is started, the second motor 242 first drives the rotating rod 243 to rotate, and under the action of the first slide groove 244, the connecting shaft 23 is pushed to slide along the slide rail 241 of the annular structure. This design ensures that the connecting shaft 23 can move smoothly on the slide rail 241, and at the same time drives the filter screen 21 in a taut state to move in the treatment box 1. In this way, not only can the waste liquid be effectively stirred, but also after the waste liquid treatment reaction is completed, the filter screen 21 can be used to filter and salvage impurities. The whole process relies on the annular path provided by the slide rail 241, which ensures the continuity and stability of the movement of the filter screen 21, thereby improving the efficiency and effect of waste liquid treatment.

[0049] See also Figure 1-Figure 4 In an optional embodiment, a second filtering mechanism 3 is provided on the processing box 1; the second filtering mechanism 3 includes a third motor 31, a spiral conveying rod 32, a conveying cylinder 33, a filter press box 34, a filter cartridge 35 and an extrusion mechanism 36; the third motor 31 is installed on the processing box 1, the spiral conveying rod 32 is coaxially connected to the third motor 31, the conveying cylinder 33 is covered on the spiral conveying rod 32, the filter press box 34 is arranged in the processing box 1, and the filter press box 34 is connected to the conveying cylinder 33, and one end of the spiral conveying rod 32 extends into the filter press box 34; the filter cartridge 35 is sleeved on the spiral conveying rod 32 in the filter press box 34; the extrusion mechanism 36 is arranged in the filter press box 34, and is used to filter impurities in the filter cartridge 35.

[0050] It should be noted that the impurities salvaged through the filter screen 21 are introduced into the position of the second filter mechanism 3, and then the filter pressure treatment is carried out in the mechanism. The specific process is as follows: the third motor 31 drives the spiral conveying rod 32 to rotate, and the impurities in the conveying cylinder 33 are gradually pushed into the filter cylinder 35 in the filter press box 34. The filter cylinder 35 is responsible for the preliminary filtration of impurities. As the impurities accumulated inside the filter cylinder 35 gradually increase, the extrusion mechanism 36 is started to apply pressure to the impurities in the filter cylinder 35 to squeeze out the moisture therein. At the same time, the spiral conveying rod 32 continues to rotate to ensure that the impurities can be continuously squeezed out through the gap between the filter cylinder 35 and the extrusion mechanism 36, so as to achieve the rapid extraction of impurities after filtration.

[0051] See also Figure 1-Figure 3 In an optional embodiment, the extrusion mechanism 36 includes a mounting frame 361, a positioning sleeve 362, a compression spring 363 and a pressure plate 364; the mounting frame 361 is fixed to the filter press box 34, the compression spring 363 is arranged between the filter press box 34 and the mounting frame 361, and a through hole is opened on the filter press box 34; the pressure plate 364 is arranged between the compression spring 363 and the filter press box 34, and is used to cover the through hole.

[0052] It should be noted that, as the spiral conveying rod 32 continues to rotate, the impurities are gradually pushed to the vicinity of the pressing plate 364 and enter the filter pressing area through the through hole. During this process, the compression spring 363 applies reverse pressure to push the pressing plate 364 to compress the impurities, thereby achieving efficient filter pressing treatment. The continuous rotation of the spiral conveying rod 32 not only ensures the continuous feeding of impurities, but also prompts the compressed impurities to pass through the gap between the pressing plate 364 and the filter press box 34 and be smoothly discharged from the gap between the compression spring 363 and the filter press box 34. This design allows the impurities to be fully dehydrated during the filter pressing process, and the filtered impurities can be quickly and smoothly discharged.

[0053] See also Figure 3-Figure 6In an optional embodiment, it also includes a material guiding mechanism 25, which is used to drive the impurities on the filter screen 21 to move; the material guiding mechanism 25 includes a protruding section 251 and a second driving mechanism 252; the protruding section 251 is arranged on the processing box 1 and connected to the slide rail 241; an opening portion is opened on the side wall of the conveying cylinder 33; the second driving mechanism 252 is used to drive the end of the connecting shaft 23 to slide on the protruding section 251, so as to drive the impurities on the filter screen 21 to be introduced into the conveying cylinder 33 through the opening portion; the second driving mechanism 252 includes a pair of cylinders 2521, a slider 2522 and a rotating block 2523; the pair of cylinders 2521 is installed on the processing box 1, the slider 2522 is fixed at the output end of the cylinder 2521, the rotating block 2523 is hinged to the slider 2522, a torsion spring is arranged at the hinge position between the rotating block 2523 and the slider 2522, and a second slide groove 2524 adapted to the end of the connecting shaft 23 is opened on the rotating block 2523.

[0054] It should be noted that when the first driving mechanism 24 drives the connecting shaft 23 to move to a position close to the conveying cylinder 33, the filter screen 21 is in a tilted upward state (such as Figure 7 As the first driving mechanism 24 continues to drive the connecting shaft 23 forward, the connecting shaft 23 contacts the rotating block 2523 and drives it to rotate. During this process, the torsion spring is compressed until the connecting shaft 23 and the rotating block 2523 are misaligned. At this time, the torsion spring releases energy, causing the rotating block 2523 to automatically reset and accurately position the connecting shaft 23 in the second sliding groove 2524 of the rotating block 2523.

[0055] Subsequently, the cylinder 2521 drives the slider 2522 to move, and the slider 2522 further pushes the rotating block 2523, so that the rotating block 2523 drives the connecting shaft 23 to move to the protruding section 251 (such as Figure 8 As shown in FIG. 1 ). At this position, the impurities on the filter screen 21 are smoothly introduced into the conveying cylinder 33 through the opening under the action of gravity. The whole process ensures that the impurities can be quickly and efficiently transferred to the conveying cylinder 33 after being salvaged from the waste liquid, optimizing the impurity separation step in the waste liquid treatment process. This mechanism not only improves the efficiency of impurity collection, but also ensures the continuity and stability of the system.

[0056] The filter screen 21 is rolled up by the rolling mechanism 22, and the connecting shaft 23 moves along the protruding section 251 until it returns to the slide rail 241. At this time, the second motor 242 controls the rotating rod 243 to rotate, so that the first slide slot 244 (such as Fig.10241). When the connecting shaft 23 moves from the protruding section 251 back to the slide rail 241, the first slide groove 244 on the rotating rod 243 receives the end of the connecting shaft 23, ensuring that it smoothly returns to the first slide groove 244. This process enables the first driving mechanism 24 to drive the connecting shaft 23 to move cyclically again, thereby realizing continuous impurity salvaging operations.

[0057] In the process of salvaging, the connecting shaft 23 moves along the side wall of the treatment box 1, which reduces the degree of stirring of the waste liquid and avoids the problem of solid impurities being broken due to excessive stirring, thereby ensuring the effect of filtration and separation. This design not only improves the salvaging efficiency, but also ensures the stability and effectiveness of the entire waste liquid treatment process; the connecting shaft 23 moves along the side wall of the treatment box 1, which significantly reduces the degree of stirring of the waste liquid and effectively avoids the problem of solid impurities being broken due to excessive stirring, thereby ensuring the effect of filtration and separation.

[0058] See also Figure 1-Figure 4 In an optional embodiment, a cleaning mechanism 26 is provided at the opening of the conveying cylinder 33; the cleaning mechanism 26 includes a roller brush 261 and a linkage mechanism 262; the roller brush 261 is rotatably connected to the processing box 1 and is used to clean impurities on the filter 21; the linkage mechanism 262 is installed on the processing box 1 and is used to drive the roller brush 261 to rotate around its axis.

[0059] It should be noted that when the filter 21 moves to the opening of the conveying cylinder 33, the rotation of the spiral conveying rod 32 drives the roller brush 261 to rotate through the linkage mechanism 262, thereby effectively cleaning the filter 21. This process can not only remove the impurities adhering to the filter 21, but also ensure that these impurities are smoothly introduced into the conveying cylinder 33. In this way, cleaning is performed immediately after the impurities are salvaged, which not only ensures the cleanliness of the filter 21, but also maintains its efficient filtering and salvaging performance, ensuring the smooth progress of subsequent processing steps.

[0060] See also Figure 1-Figure 4 In an optional embodiment, it can be understood that the present application does not limit the specific structure and installation method of the linkage mechanism 262. The following only provides a feasible technical solution for reference: the linkage mechanism 262 includes a driving gear 2621 and a driven gear 2622; the driving gear 2621 is coaxially fixed to the spiral conveying rod 32, and the driven gear 2622 is meshed with the driving gear 2621 and coaxially fixed to the roller brush 261.

[0061] It should be noted that when the spiral conveying rod 32 rotates, it drives the driving gear 2621 to rotate. Then, the driving gear 2621 drives the driven gear 2622 meshing therewith to rotate, and the driven gear 2622 in turn drives the roller brush 261 to rotate. Through this gear transmission mechanism, the linkage between the spiral conveying rod 32 and the roller brush 261 is realized, ensuring that the roller brush 261 can rotate synchronously and effectively clean the impurities on the filter screen 21. This design ensures that the filter screen 21 can be cleaned in time after each impurity salvage is completed, maintaining its efficient filtering and salvage performance.

[0065] Step 2: Filtration and salvage: After the waste liquid treatment is completed, the reeling mechanism 22 controls the reeling or unreeling of the filter screen 21, and at the same time the first driving mechanism 24 controls the connecting shaft 23 to move upward from the bottom of the treatment box 1 along the inner wall of the treatment box 1, thereby driving the filter screen 21 to salvage the flocculants in the treatment box 1.
