Description

Technical Field

[0001] This application relates to the field of waste liquid recycling technology, and in particular to a device for recycling waste liquid from quartz sand pickling. Background Technology

[0002] A related technology (publication number: CN220758341U) discloses a quartz sand pickling waste liquid recovery device, including a housing unit and a filtration unit. The housing unit includes at least two filtration housings with progressively decreasing heights. Each filtration housing has an acid inlet and an acid outlet, and adjacent filtration housings are connected by a connecting pipe. The filtration unit includes a filtration assembly disposed within the filtration housing. The filtration assembly includes a filter bag and a filter plate, which are arranged sequentially along the acid flow direction. The filter bag is provided with a connecting assembly for cooperating with a lifting device to move the filter bag to a designated position.

[0003] In the process of implementing the technical solution disclosed herein, at least the following problems were found in the related technologies:

[0004] The quartz sand pickling waste liquid recovery device utilizes the pressure difference created by the height difference between multiple filter boxes to achieve continuous inflow and outflow of acid. The filter components then filter out the quartz sand and impurities in the acid, thus enabling the recycling and reuse of the acid. However, when the acid level in the filter box is lower than the height of the connecting pipe, continuous inflow and outflow of acid cannot be achieved, preventing secondary filtration.

[0037] Combination Figures 1 to 5As shown, this embodiment of the present disclosure provides a quartz sand pickling waste liquid recovery device, including a support frame 1, a filter barrel 2, a first barrel cover 3, a first mesh cover 4, a first filter bag 5, a second barrel cover 6, a second mesh cover 7, a second filter bag 8, and a driving component. The support frame 1 is used to abut against the ground, thereby supporting the entire device. The filter barrel 2 is installed on the top wall of the support frame 1, used to store acid liquid and accommodate the first mesh cover 4, etc. The first barrel cover 3 includes a through hole, used to open or close the opening of the filter barrel 2, and the through hole allows the second mesh cover 7, etc., to pass through. The first mesh cover 4 is detachably installed on the bottom surface of the first barrel cover 3 and can be accommodated inside the filter barrel 2, used to support and accommodate the first filter bag 5. The first filter bag 5 is installed inside the first mesh cover 4, used for initial filtration of the acid liquid. The second barrel cover 6 includes an injection port, used to open or close the through hole, and the injection port is used to inject acid liquid. The second mesh cover 7 is detachably installed on the bottom surface of the second barrel cover 6 and can be accommodated inside the first filter bag 5 through the through hole, serving to support and accommodate the second filter bag 8. The second filter bag 8 is installed inside the second mesh cover 7 for secondary filtration of the acid solution. Driving components are respectively installed between the top wall of the support frame 1 and the first barrel cover 3 and the second barrel cover 6, providing driving force to drive the first barrel cover 3 and the second barrel cover 6 to perform lifting and rotating movements, respectively. Under the drive of the driving components, the first barrel cover 3 seals the opening of the filter barrel 2, and the second barrel cover 6 seals the through hole.

[0038] This embodiment of the invention provides a quartz sand pickling waste liquid recovery device. By controlling the drive mechanism, the first barrel cover 3 and the second barrel cover 6 can be driven to move vertically and rotate. When the first barrel cover 3 moves vertically and rotates, the position of the first mesh cover 4 can be adjusted, allowing it to move into the filter barrel 2 or be placed on the ground. When the second barrel cover 6 moves vertically and rotates, the position of the second mesh cover 7 can be adjusted, allowing it to move into the through hole or be placed on the ground. After the first mesh cover 4 moves into the filter barrel 2 and the second mesh cover 7 moves into the through hole, acid is added to the injection port. Under the action of gravity, the acid flows sequentially through the second filter bag 8 and the first filter bag 5, unaffected by pressure difference. The acid can continuously flow through the second filter bag 8 and the first filter bag 5, achieving secondary filtration. Once the first mesh cover 4 and the second mesh cover 7 are both placed on the ground, it becomes easy to clean the separated quartz sand and impurities inside the first filter bag 5 and the second filter bag 8. Furthermore, the first mesh cover 4 and the second mesh cover 7 can be replaced with filter cylinders, which, while supporting and accommodating the first and second filter screens, also perform secondary filtration of the acid solution.

[0039] Optionally, combined Figure 1 , Figure 2 and Figure 5As shown, the driving components include a first rotating shaft 9, a first bending plate 10, a linear slide 11, a second bending plate 12, and support columns 13. The first rotating shaft 9 is rotatably mounted through the top wall of the support frame 1 along the axial direction of the filter barrel 2, and is located on both sides of the filter barrel 2 along the radial direction. Both first rotating shafts 9 can rotate relative to the top wall of the support frame 1. The first bending plates 10 are respectively installed at the top ends of the two first rotating shafts 9 and rotate under the drive of the two first rotating shafts 9. The linear slides 11 are respectively installed on the two first bending plates 10 along the axial direction of the filter barrel 2, and are used to provide driving force to achieve linear movement. The second bending plates 12 are respectively installed at the moving ends of the two linear slides 11 and move up and down under the drive of the two linear slides 11. The support columns 13 are respectively installed on the two second bending plates 12 along the axial direction of the filter barrel 2, and are used to provide support and elevation. The first barrel cover 3 and the second barrel cover 6 are respectively installed at the top ends of the two support columns 13. The first rotating shafts 9 on both sides can be rotated in a controlled manner to drive the first bending plates 10 on both sides to rotate respectively.

[0040] In this embodiment, the first rotating shafts 9 on both sides can rotate under the drive of an external force, thereby driving the first bending plates 10 on both sides to rotate, and finally driving the first bucket lid 3 and the second bucket lid 6 to rotate respectively. By controlling the linear slides 11 on both sides to work, the second bending plates 12 on both sides can be driven to move up and down, and finally driving the first bucket lid 3 and the second bucket lid 6 to move up and down respectively.

[0041] Optionally, combined Figure 1 , Figure 2 and Figure 5 As shown, the driving component also includes a second rotating shaft 14, a first synchronous pulley, a second synchronous pulley, and a synchronous toothed belt 15. The second rotating shaft 14 is rotatably mounted on the top wall of the support frame 1 along the axial direction of the filter barrel 2, and is located between the filter barrel 2 and the two first rotating shafts 9 on both sides. Both second rotating shafts 14 can rotate relative to the top wall of the support frame 1. The first synchronous pulleys are respectively mounted on the two second rotating shafts 14 and rotate under the drive of the two second rotating shafts 14. The second synchronous pulleys are respectively mounted on the two first rotating shafts 9 and are used to drive the rotation of the two first rotating shafts 9. The synchronous toothed belt 15 is respectively fitted between the first and second synchronous pulleys on the same side and is used to transmit driving force. The two second rotating shafts 14 can be controlled to rotate to drive the rotation of the two first rotating shafts 9.

[0042] In this embodiment, the two second rotating shafts 14 can rotate under the drive of an external force, thereby driving the two first synchronous pulleys to rotate. The two synchronous toothed belts 15 can then drive the two second synchronous pulleys to rotate, which in turn drives the two first pulleys to rotate, ultimately causing the first lid 3 and the second lid 6 to rotate respectively.

[0043] Optionally, combined Figure 1 and Figure 5 As shown, the driving component also includes support rods 16, mounting plates 17, motors 18, and couplings. Support rods 16 are mounted on the top wall of the support frame 1, along the radial direction of the filter barrel 2, located on both sides of the filter barrel 2. The support rods 16 on both sides support the mounting plates 17. Mounting plates 17 are mounted on the support rods 16 on both sides, respectively, and are used to support the motors 18. Motors 18 are mounted on the mounting plates 17 on both sides, with the rotating ends of the motors 18 facing the second rotating shafts 14 on both sides, respectively, to provide driving force to achieve the rotational motion function. Couplings are installed between the rotating ends of the motors 18 on both sides and the second rotating shafts 14 on both sides, respectively, to transmit driving force.

[0044] In this embodiment, by controlling the operation of the motors 18 on both sides, the second rotating shafts 14 on both sides can be driven to rotate through the couplings on both sides, which in turn drive the first bucket lid 3 and the second bucket lid 6 to rotate.

[0045] Optionally, combined Figure 1 , Figure 2 and Figure 5 As shown, the drive unit also includes bearing housings 19 and first bearings. The bearing housings 19 are mounted on the top wall of the support frame 1 and are respectively sleeved on the first rotating shafts 9 on both sides and the second rotating shafts 14 on both sides. The first bearings are respectively installed between the first rotating shafts 9 on both sides and the second rotating shafts 14 on both sides and the four bearing housings 19.

[0046] In this embodiment, four bearing seats 19 are installed on the top wall of the support frame 1, respectively for supporting and mounting the first bearings and for limiting the position of the first bearings. The four first bearings are respectively used to support and mount the first rotating shafts 9 on both sides and the second rotating shafts 14 on both sides, reducing the frictional force on the first rotating shafts 9 on both sides and the second rotating shafts 14 on both sides, and improving the rotational accuracy of the first rotating shafts 9 on both sides and the second rotating shafts 14 on both sides.

[0047] Optionally, combined Figure 1 and Figure 3As shown, the filter also includes a first mounting block 20, a first bolt 21, a first clamping plate 22, and a first clamping block 23. The first mounting block 20 is mounted on the bottom surface of the first barrel cover 3, along the radial direction of the filter barrel 2, located on both sides of the through hole. The two first mounting blocks 20 on each side are used to support the rotatable first bolt 21. The first bolt 21 is threadedly connected to the two first mounting blocks 20 on each side along the radial direction of the filter barrel 2. The first clamping plates 22 are rotatably mounted on the opposite ends of the two first bolts 21 on each side, and can rotate relative to the two first bolts 21 on each side. The first clamping blocks 23 are mounted on the opposite surfaces of the two first clamping plates 22 on each side, and are used to abut against the first mesh cover 4. The opposite surfaces of the two first clamping blocks 23 on each side include a first limiting groove that matches the port of the first mesh cover 4, and are used to limit movement to improve the clamping and fixing effect.

[0048] In this embodiment, rotating the first bolts 21 on both sides allows the first clamping plates 22 on both sides to move towards each other or in the same direction through the interaction between the threads. This, in turn, causes the first clamping block 23 to abut against or separate from the first mesh cover 4, thereby clamping or releasing the first mesh cover 4. This facilitates the installation or removal of the first mesh cover 4, and consequently facilitates the cleaning of the first filter bag 5 inside it.

[0049] Optionally, combined Figure 1 and Figure 3 As shown, it also includes a first cam bearing 24. The first cam bearing 24 is respectively installed on the first clamping plates 22 on both sides, and both abut against the bottom surface of the first barrel cover 3.

[0050] In this embodiment, the first cam bearings 24 on both sides serve as guide supports so that the first clamping plates 22 on both sides do not rotate with the rotation of the first bolts 21 on both sides.

[0051] Optionally, combined Figure 1 and Figure 3 As shown, it also includes a second bearing, which is installed between the first movable plates on both sides and the first bolts 21 on both sides.

[0052] In this embodiment, the second bearings on both sides are used to reduce the friction between the first clamping plates 22 on both sides and the first bolts 21 on both sides, thereby reducing wear and damage.

[0053] Optionally, combined Figure 1 , Figure 4 and Figure 5As shown, the filter 2 also includes a second mounting block 25, a second bolt 26, a second clamping plate 27, and a second clamping block 28. The second mounting block 25 is installed on the bottom surface of the second cover 6, along the radial direction of the filter 2, located on both sides of the injection port. The two second mounting blocks 25 on each side are used to support the rotatable second bolt 26. The second bolt 26 is threadedly connected to the two second mounting blocks 25 along the radial direction of the filter 2. The second clamping plates 27 are rotatably installed on the opposite ends of the two second bolts 26 on each side, and can rotate relative to the two second bolts 26. The second clamping blocks 28 are installed on the opposite surfaces of the two second clamping plates 27 on each side, and are used to abut against the second mesh cover 7. The opposite surfaces of the two second clamping blocks 28 on each side include a second limiting groove that matches the port of the second mesh cover 7, and are used to limit movement to improve the clamping and fixing effect.

[0054] In this embodiment, rotating the second bolts 26 on both sides allows the second clamping plates 27 on both sides to move towards each other or in the same direction through the interaction between the threads. This, in turn, causes the second clamping block 28 to abut against or separate from the second mesh cover 7, thereby clamping or releasing the second mesh cover 7. This facilitates the installation or removal of the second mesh cover 7, and consequently, the cleaning of the second filter bag 8 inside it.

[0055] Optionally, combined Figure 1 , Figure 4 and Figure 5 As shown, it also includes a second cam bearing 29. The second cam bearing 29 is respectively installed on the second clamping plates 27 on both sides, and both abut against the bottom surface of the second barrel cover 6.

[0056] In this embodiment, the second cam bearings 29 on both sides serve as guide supports so that the second clamping plates 27 on both sides do not rotate with the rotation of the second bolts 26 on both sides.

[0057] Optionally, combined Figure 1 and Figure 4 As shown, it also includes a third bearing, which is installed between the second movable plates on both sides and the second bolts 26 on both sides.

[0058] In this embodiment, the third bearings on both sides are used to reduce the friction between the second clamping plates 27 on both sides and the second bolts 21 on both sides, thereby reducing wear and damage.

[0059] Optionally, combined Figure 1 and Figure 5 As shown, it also includes a valve. The valve is installed at the drain port of the filter tank 2.

[0060] In this embodiment of the disclosure, the valve is used to open or close the drain port to switch the conduction state of the drain port.
