Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically a skid-mounted wastewater treatment device for mining areas. Background Technology

[0002] Mining areas generate a large amount of wastewater during production, which needs to be treated before discharge. Currently, skid-mounted wastewater treatment units are the most commonly used, as they are convenient to transport and install and easy to use. However, existing skid-mounted wastewater treatment units still have certain shortcomings. When treating wastewater from mining areas, skid-mounted wastewater treatment units need to first use screens to block larger suspended and floating solids (such as wood chips, fibers, hair, plastics, etc.) from passing through the wastewater, thus achieving preliminary filtration. However, after a period of filtration, the suspended and floating solids blocked by the screens will accumulate at the screens, requiring staff to stop the machine for cleaning. This operation is cumbersome, time-consuming, labor-intensive, and increases the workload of the staff. Furthermore, the need to stop the machine for cleaning also affects the efficiency of wastewater treatment. Summary of the Invention

[0003] The purpose of this invention is to provide a skid-mounted wastewater treatment device for mining areas, so as to solve the problem mentioned in the background art that the existing skid-mounted wastewater treatment devices are relatively cumbersome to operate when cleaning the suspended and floating matter accumulated at the screen.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A skid-mounted wastewater treatment device for mining areas includes: a sedimentation tank, one end of which is fixedly provided with a pipe support plate, and a wastewater conveying pipe is inserted into the pipe support plate to convey wastewater into the sedimentation tank. A wastewater receiving and filtering assembly is fixedly installed in a sedimentation tank to filter wastewater. A space partition component, which is installed on the wastewater receiving and filtering component to partition its internal space; A drive assembly is installed on the sedimentation tank and cooperates with the space partition assembly to move the space partition assembly. A blocking component is movably installed on the wastewater receiving and filtering component, and is moved by a space partition component to block the wastewater receiving and filtering component; The cleaning component is also movably installed on the sewage receiving and filtering component to clean suspended and floating solids in the sewage receiving and filtering component.

[0005] Furthermore, the wastewater receiving and filtering assembly is a receiving box, and a drain hole is provided at one end of the receiving box for wastewater discharge.

[0006] Furthermore, two partition panels are symmetrically fixed inside the receiving box, dividing the inside of the receiving box into a water accumulation chamber and a sewage discharge chamber.

[0007] Furthermore, the space partition assembly includes: a movable barrier plate, which is inserted between two partition panels; The movable push block is movably connected to the movable baffle plate, and the movable push block is moved by the movable baffle plate.

[0008] Furthermore, the space partition assembly also includes: a first movable push bar, which is movably connected to a movable barrier plate, and the movable barrier plate is moved by the first movable push bar; The second movable pusher is movably mounted on the first movable pusher.

[0009] Furthermore, the movable barrier moves downwards and contacts the inner bottom surface of the receiving box to block the water accumulation chamber and the sewage discharge chamber.

[0010] Furthermore, the driving component includes: a first cylinder, which is fixedly mounted on the sedimentation tank; The L-shaped pusher is fixedly mounted on the cylinder rod of the first cylinder.

[0011] Furthermore, the L-shaped pusher cooperates with the first movable push bar and the second movable push bar to drive the first movable push bar and the second movable push bar to move.

[0012] Furthermore, the sealing component is a sealing plate, and a sealing post is fixedly installed on the sealing plate to seal the drainage hole.

[0013] Furthermore, the cleaning assembly includes: a first pushing support plate, which cooperates with an L-shaped pusher and is driven to move upward by the L-shaped pusher; The second pusher plate is installed on the first pusher plate and works in conjunction with the first pusher plate to push suspended and floating objects out of the receiving box.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a reasonable structural design and strong functionality, and has the following advantages: 1. A receiving box is fixedly installed in the sedimentation tank, and a drainage hole is provided on the receiving box. The receiving box replaces the bar screen and can quickly clean up the accumulated suspended solids and floating objects without stopping the machine. The operation is simple, convenient and quick, which greatly reduces the workload of the staff and improves the efficiency of cleaning suspended solids and floating objects.

[0015] 2. When it is necessary to clean the suspended and floating objects in the receiving box, the drainage hole can be blocked by the sealing plate, and the foreign objects stuck in the drainage can be pushed into the sewage chamber by the sealing column on the sealing plate, which can clean the drainage hole and prevent suspended and floating objects from clogging the drainage hole.

[0016] 3. After the drain hole is blocked, the water accumulation chamber and the sewage chamber are in a state of separation. As the first pusher plate moves upward, the suspended and floating objects accumulated in the sewage chamber can be pushed upward and moved out of the sewage chamber. Then, the final cleaning can be achieved under the action of the second pusher plate, saving manpower. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] This invention provides a technical solution: like Figure 1 , Figure 2 and Figure 3As shown, a skid-mounted wastewater treatment device for mining areas includes: a sedimentation tank 1, a wastewater receiving and filtering assembly, a drive assembly, a sealing assembly, and a cleaning assembly. A pipe support plate 11 is welded to one end of the sedimentation tank 1, and a wastewater conveying pipe 12 is inserted into the pipe support plate 11, through which wastewater is conveyed into the sedimentation tank 1. The wastewater receiving and filtering assembly is fixedly installed in the sedimentation tank 1. The wastewater conveyed by the wastewater conveying pipe 12 enters the wastewater receiving and filtering assembly, causing larger suspended solids and floating matter to accumulate within it. A space partition assembly is installed on the wastewater receiving and filtering assembly to partition its internal space, facilitating the removal of accumulated suspended solids and floating matter during wastewater treatment. The drive assembly is installed on the sedimentation tank 1 and works in conjunction with the space partition assembly, moving the space partition assembly to achieve the spatial partitioning within the wastewater receiving and filtering assembly.

[0033] The sealing component is movable on the sewage receiving and filtering component. It is moved by the space partition component to seal the sewage receiving and filtering component. The cleaning component is also movable on the sewage receiving and filtering component to clean the suspended and floating solids in the sewage receiving and filtering component.

[0034] like Figure 1 and Figure 2 As shown, an installation platform 13 is welded and fixed to one side of the outer wall of the sedimentation tank 1 by welding process, and a drain pipe 14 is welded and fixed to the end of the sedimentation tank 1 away from the pipe support plate 11 by welding process, through which the settled sewage is discharged.

[0035] like Figure 1 ,and Figure 7 As shown, the wastewater receiving and filtering component is a receiving box 2. The receiving box 2 can be fixedly installed in the sedimentation tank 1 with screws. One end of the receiving box 2 is provided with a drain hole 25. Wastewater is discharged through the drain hole 25. That is, suspended solids and floating solids larger than the size of the drain hole 25 cannot pass through the drain hole 25.

[0036] Specifically, an upper extension baffle 26 is integrally formed and fixed at the upper end of the box wall where the drainage hole 25 is located, and support strips 27 are symmetrically welded and fixed at the upper ends of both sides of the receiving box 2. A protruding plate 271 is integrally formed and fixed at one end of the support strip 27. A support mating rod 272 is welded and fixed on the protruding plate 271. A limit stop 273 is welded and fixed at the end of the support mating rod 272 away from the protruding plate 271.

[0037] In addition, a protruding support plate 28 is integrally formed and fixed on the support strip 27 on one side of the receiving box 2. A second guide hole 281 is provided on the protruding support plate 28. An inclined slide 29 is welded and fixed on the support strip 27 on the other side of the receiving box 2 by welding process. The surface of the inclined slide 29 is smooth and burr-free.

[0038] The receiving box 2 has two partition plates 21 that are symmetrically welded and fixed inside by welding process. The upper end of the partition plate 21 is provided with a first guide hole 22, and the partition plate 21 divides the inside of the receiving box 2 into a water accumulation chamber 23 and a sewage discharge chamber 24. The upper end surface of the partition plate 21 is flush with the upper end surface of the upper extension baffle 26.

[0039] like Figure 4 , Figure 5 , Figure 6 and Figure 8 As shown, the space partition assembly includes: a movable barrier plate 3, a movable push block 4, a first movable push bar 5, and a second movable push bar 6. The movable barrier plate 3 is inserted between two partition boxes 21 and is in contact with the two partition boxes 21. The surfaces of the movable barrier plate 3 and the partition boxes 21 are smooth and burr-free.

[0040] In addition, a connecting support strip 31 is symmetrically and integrally formed and fixed on the upper end of the movable barrier plate 3. A first guide rod 32 is welded and fixed on the lower end surface of the connecting support strip 31 by welding process. The first guide rod 32 is inserted into the first guide hole 22. The movable barrier plate 3 is restricted by the cooperation of the first guide rod 32 and the first guide hole 22, so that the movable barrier plate 3 can only move up and down between the two partition boxes 21, and the end faces of the two ends of the movable barrier plate 3 are flush with the end faces of the two ends of the partition box 21 respectively.

[0041] A first connecting frame 33 is welded to the connecting support strip 31. A matching connecting rod 34 is hinged to the first connecting frame 33. A second connecting frame 42 is welded to the movable push block 4. The second connecting frame 42 is hinged to the matching connecting rod 34 on one side of the movable baffle plate 3. Thus, the movable push block 4 and the movable baffle plate 3 can be connected by the matching connecting rod 34 on this side of the movable baffle plate 3. The movable baffle plate 3 drives the movable push block 4 to move. In order to further restrict the movable push block 4, a first support insertion hole 41 is provided on the movable push block 4. The inner wall of the first support insertion hole 41 is smooth and burr-free. The first support insertion hole 41 is matched with the support matching rod 272 on one side of the receiving box 2. The matching of the two can effectively restrict the movable push block 4, so that the movable push block 4 can only move along the matching support matching rod 272.

[0042] like Figure 5 , Figure 8 and Figure 9 As shown, a connecting plate 52 is welded to one side of the first movable push bar 5. A second support insertion hole 53 is provided on the connecting plate 52. The inner wall of the second support insertion hole 53 is smooth and burr-free. The second support insertion hole 53 cooperates with the support mating rod 272 on the other side of the receiving box 2. Through the cooperation of the two, the first movable push bar 5 can be effectively restricted, so that the first movable push bar 5 can only move along the support mating rod 272 that it cooperates with. In addition, a third connecting frame 54 is also welded to the connecting plate 52. The third connecting frame 54 is hinged to the mating connecting rod 34 on the other side of the movable barrier plate 3. Through this mating connecting rod 34, the movable connection between the first movable push bar 5 and the movable barrier plate 3 is realized, so that the movable barrier plate 3 can be moved by the first movable push bar 5.

[0043] like Figure 9 and Figure 10 As shown, the second movable pusher 6 is movably mounted on the first movable pusher 5. Specifically, the first movable pusher 5 has an inwardly recessed groove 51, and two mating through holes 511 are formed on the groove wall of the inwardly recessed groove 51. A first mating inclined surface 55 is integrally formed and fixed at the lower end of the first movable pusher 5. The surfaces of the first mating inclined surface 55 and the first movable pusher 5 are smooth and burr-free. The second movable pusher 6 is located at the opening of the inwardly recessed groove 51. A second mating inclined surface 61 is integrally formed and fixed at the lower end of the second movable pusher 6. The surfaces of the second mating inclined surface 61 and the second movable pusher 6 are smooth and burr-free. Two mating inserts 62 are welded and fixed on the second movable pusher 6 by welding. The two mating inserts 62 are respectively inserted into the two mating through holes 511. A limiting mating block 63 is welded and fixed on the mating inserts 62 on the lower side of the second movable pusher 6 by welding. When the second movable pusher 6 is not moving into the inwardly recessed groove 51, the limiting mating block 63 is in contact with the outer end face of the first movable pusher 5.

[0044] The movable baffle 3 moves downward and contacts the inner bottom surface of the receiving box 2, blocking the water accumulation chamber 23 and the sewage discharge chamber 24. This locks the suspended and floating objects accumulated at the drain hole 25 in the sewage discharge chamber 24, preventing them from moving back into the water accumulation chamber 23.

[0045] like Figure 1As shown, the drive assembly includes a first cylinder 7 and an L-shaped pusher 71. The first cylinder 7 is fixedly mounted on the mounting base 13 on the sedimentation tank 1 by screws. The L-shaped pusher 71 is fixedly mounted on the cylinder rod of the first cylinder 7 by screws. In this way, the L-shaped pusher 71 can be driven to move up and down under the extension and retraction of the cylinder rod. A mating push plate 72 is integrally formed and fixed on the lower side of the L-shaped pusher 71, and a pusher wheel 73 is installed on the mating push plate 72.

[0046] When the L-shaped pusher 71 moves upward, the push roller 73 will engage with the first mating inclined surface 55 on the first movable pusher 5 and the second mating inclined surface 61 on the second movable pusher 6, thus driving the first movable pusher 5 and the second movable pusher 6 to move.

[0047] like Figure 4 , Figure 6 and Figure 11 As shown, the sealing assembly is a sealing plate 8, on which a sealing post 81 is fixedly installed. The sealing post 81 seals the drain hole 25. When the sealing post 81 seals the drain hole 25, the sealing post 81 is inserted into the drain hole 25 and contacts the inner wall of the drain hole 25. At this time, the end face of the sealing post 81 away from the sealing plate 8 is flush with the inner wall of the drain hole 25.

[0048] In addition, support rods 82 are symmetrically and integrally formed and fixed on both sides of the upper end of the sealing plate 8. A first support strip 83 is welded and fixed on the support rod 82 by welding process. A second support strip 84 is integrally formed and fixed on the end of the first support strip 83 away from the sealing plate 8. A movable sleeve hole 85 is opened on the second support strip 84. A support mating rod 272 is inserted into the movable sleeve hole 85. A return spring 86 is sleeved on the support mating rod 272. The two ends of the return spring 86 are welded to the second support strip 84 and the raised plate 271 respectively.

[0049] like Figure 5 and Figure 10 As shown, the second support bar 84 on one side of the sealing support plate 8 contacts the movable push block 4, and the mating rod 62 on the upper side of the second movable push bar 6 contacts the second support bar 84 on the other side of the sealing support plate 8. When the sealing support plate 8 does not move towards the receiving box 2, the second support bar 84 that contacts the mating rod 62 also contacts the first movable push bar 5.

[0050] like Figure 6 , Figure 12 and Figure 13As shown, the cleaning assembly includes a first pusher plate 9 and a second pusher plate 98. The first pusher plate 9 is inserted into the sewage chamber 24. When it is not moving upward, it is in contact with the inner bottom surface of the receiving box 2. The end faces of the two ends of the first pusher plate 9 are in contact with the box wall and the partition plate 21 of the receiving box 2, respectively. A connecting rod 91 is welded and fixed on the first pusher plate 9. A supporting top plate 92 is welded and fixed on the upper end of the connecting rod 91 using the same welding process. When the L-shaped pusher 71 moves upward, it will contact the supporting top plate 92. In this way, the first pusher plate 9 and the L-shaped pusher 71 can cooperate. The L-shaped pusher 71 pushes the supporting top plate 92 upward, which in turn drives the first pusher plate 9 to move upward.

[0051] An assembly support plate 93 is integrally formed and fixed on the supporting top plate 92. A mating plate frame 94 is symmetrically welded and fixed on the assembly support plate 93. A mating guide rod 95 is welded and fixed on the mating plate frame 94. The other end of the mating guide rod 95 is welded and fixed to the assembly support plate 93. A second cylinder 97 is also fixedly installed on the assembly support plate 93 by screws. A second pushing support plate 98 is fixedly installed on the cylinder rod of the second cylinder 97 by screws. Symmetrical mating guide holes 981 are opened on the second pushing support plate 98, and mating guide rods 95 are inserted into the mating guide holes 981. The guide rod 95 and the guide hole 981 cooperate to guide and support the second pusher plate 98. The second pusher plate 98 cooperates with the first pusher plate 9 to push suspended and floating objects out of the receiving box 2. The second pusher plate 98 is in contact with the inner wall of the receiving box 2 and the partition plate 21. In addition, a second guide rod 96 is symmetrically welded to the lower end face of the supporting top plate 92. The second guide rod 96 is inserted into the second guide hole 281. The cooperation between the second guide rod 96 and the second guide hole 281 guides and limits the first pusher plate 9.

[0052] When it is necessary to clean the suspended and floating matter accumulated in the receiving box 2, the first cylinder 7 is activated to drive the L-shaped pusher 71 to move upward. As the L-shaped pusher 71 moves upward, the first movable push bar 5 can be moved by the cooperation of the push roller 73 and the first mating inclined surface 55. As the first movable push bar 5 moves, it will drive the second bearing bar 84 to move, which in turn will drive the sealing bearing plate 8 to move. At this time, the sealing column 81 has not yet been inserted into the drain hole 25. As the first movable push bar 5 moves, it will drive the movable baffle plate 3 to move downward under the action of the connecting rod 34, so that the lower end face of the movable baffle plate 3 contacts the inner bottom surface of the receiving box 2, separating the water accumulation chamber 23 and the sewage discharge chamber 24. At this time, it is possible to operate without stopping the machine. Sewage can continue to be transported into the water accumulation chamber 23, and at the same time, the suspended and floating matter in the sewage discharge chamber 24 can be cleaned.

[0053] After the water collection chamber 23 and the sewage discharge chamber 24 are separated, sewage will no longer enter the sewage discharge chamber 24. Once the sewage in the sewage discharge chamber 24 flows out from the drain hole 25, the first cylinder 7 is restarted to drive the L-shaped pusher 71 to continue moving upwards. As the L-shaped pusher 71 continues to move upwards, the push roller 73 will contact the second mating inclined surface 61 on the second movable push bar 6. Thus, with the cooperation of the push roller 73 and the second mating inclined surface 61, the second movable push bar 6 can be driven to retract into the inward groove 51. The movement of the second movable push bar 6, under the action of the cooperating insert rod 62 on the upper side of the second movable push bar 6, pushes the second support bar 84 in contact with it to move, thereby enabling the sealing support plate 8 to continue to move, so that the sealing post 81 on the sealing support plate 8 can be inserted into the drain hole 25. In this way, the drain hole 25 can be blocked, which not only pushes the impurities accumulated in the drain hole 25 into the sewage chamber 24, but also prevents suspended and floating objects from entering the drain hole 25 when the first push support plate 9 pushes the suspended and floating objects upward.

[0054] After the drain hole 25 is blocked, as the L-shaped pusher 71 continues to move upward, it will come into contact with the supporting top plate 92. Under the action of the L-shaped pusher 71, the supporting top plate 92 will be pushed upward, which in turn will drive the first pushing support plate 9 to move upward. Under the action of the first pushing support plate 9, the suspended and floating objects in the sewage chamber 24 can be pushed upward, so that they are moved out of the sewage chamber 24 and placed between the partition box plate 21 and the upper extension baffle 26. Then, the second cylinder 97 is activated to drive the second pushing support plate 98 to move towards the inclined slide 29. In this way, under the action of the second pushing support plate 98, the suspended and floating objects can be pushed towards the inclined slide 29, so that the suspended and floating objects can slide out from the inclined slide 29. Simply place a container at the inclined slide 29, which is very convenient and quick, and no cleaning operation is required.

[0055] After a cleaning cycle is completed, the second cylinder 97 drives the second pusher plate 98 to reset, and the first cylinder 7 drives the L-shaped pusher 71 to move downwards to reset. Under the weight of its own, the first pusher plate 9 can move downwards and reset along with the L-shaped pusher 71. In addition, the reset spring 86 will drive the sealing plate 8 to reset, which in turn will drive the first movable push bar 5 and the second movable push bar 6 to reset, so that the movable baffle plate 3 moves upwards, and the water accumulation chamber 23 and the sewage discharge chamber 24 are connected again, so that sewage filtration can continue.

[0056] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
