Description

Technical Field

[0001] This utility model relates to the technical field of raw material filtration devices, specifically a raw material filtration device for preparing polyaluminum chloride using aluminum-containing waste hydrochloric acid. Background Technology

[0002] With the acceleration of industrialization, the treatment and resource utilization of aluminum-containing waste hydrochloric acid has become an important issue in the fields of environmental protection and circular economy. Polyaluminum chloride, as a highly efficient inorganic polymer flocculant, is widely used in the water treatment industry. The purification of raw materials during its preparation process is particularly critical. At present, most raw material filtration devices on the market adopt a fixed structure of primary and secondary filter plates. Although they meet basic filtration requirements to a certain extent, they have revealed many shortcomings in practical applications.

[0003] In the existing technology, the traditional filtration device has a relatively fixed structure of primary and secondary filter plates, which makes disassembly and maintenance complicated and cumbersome. Each time the filter media is maintained or replaced, the operator needs to use additional auxiliary tools and spend a lot of time and energy to disassemble and reinstall it. This not only increases the labor intensity but also prolongs the downtime of the equipment, thereby affecting production efficiency and resulting in poor performance of the filtration device.

[0004] Therefore, there is a need for a raw material filtration device for preparing polyaluminum chloride using aluminum-containing waste hydrochloric acid, in order to solve the problem that the existing raw material filtration devices have a relatively fixed filter plate structure, which requires operators to use tools for disassembly and maintenance, making them inconvenient for operators and affecting the effectiveness of the filtration device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a raw material filtration device for preparing polyaluminum chloride using aluminum-containing waste hydrochloric acid, comprising a filter device body, a fixing component, a connecting plate, a primary filter plate, and a secondary filter plate. The filter device body has two mounting grooves on both its upper and lower inner walls, and a support frame is inserted into the inner wall of each pair of mounting grooves. The filter device body has two through grooves on its right side, and multiple fitting grooves are provided on both its upper and lower inner walls.

[0007] Preferably, the connecting plate on the right side has sliding grooves on both the upper and lower sides, and a limiting plate is installed on the inner wall of the sliding groove. A limiting plate is installed on one side of the limiting plate, and an elastic element is installed on the other side. A connecting rope is installed on the adjacent side of the upper and lower limiting plates. A knob is rotatably connected to the middle of the connecting plate on the right side. A limiting groove is opened on the adjacent side of the two fixing elements on the right side.

[0008] Preferably, the adjacent sides of the elastic elements on both the upper and lower sides are installed on the inner wall of the slide groove, and the opposite sides of the limiting plates on both the upper and lower sides pass through the right connecting plate and are inserted into the inner wall of the limiting groove.

[0009] Preferably, the adjacent ends of the connecting ropes on both the upper and lower sides are installed between the knob and the knob.

[0010] Preferably, the support frame has insertion slots on both the front and rear sides, insertion plates are installed on the inner walls of the insertion slots, a retaining ball is installed on the right side of the insertion plates, and two retaining slots are opened on the right side of the inner wall of the support frame.

[0011] Preferably, the two upper plug-in plates are installed between the primary filter plate and the two lower plug-in plates are installed between the secondary filter plate, and the ball is inserted into the inner wall of the slot.

[0012] Preferably, the through groove and the mounting groove are interconnected, the rubber protrusions on both the upper and lower sides are engaged with the inner wall of the fitting groove, the support frames on both the upper and lower sides are installed between the right side connecting plate, and the right part of the support frame is inserted into the inner wall of the through groove, the primary filter plate is installed on the inner wall of the upper support frame, and the secondary filter plate is installed on the inner wall of the lower support frame.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] This utility model proposes a raw material filtration device for preparing polyaluminum chloride using aluminum-containing waste hydrochloric acid. By rotating a knob, two connecting ropes are wound around the outside of the device, thereby pulling the upper and lower limiting plates towards each other and disengaging them from the limiting groove. Simultaneously, the elastic element is compressed on the inner wall of the slide groove. At this point, the right connecting plate can be pulled to the right, causing the two support frames to disengage from the filter device body for maintenance of the primary and secondary filter plates. After maintenance, the support frames are reset, and the knob is released. The elastic force of the elastic element allows the limiting plates to re-insert into the limiting groove, ensuring convenient disassembly and maintenance. In addition, when the support frames are reset, multiple rubber protrusions on their right side engage with the fitting groove, thereby improving the sealing performance of the support frames after insertion and enhancing the effectiveness of the filtration device.

[0024] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Example 1: Please refer to Figures 1 to 8This utility model provides a technical solution: a raw material filtration device for preparing polyaluminum chloride using aluminum-containing waste hydrochloric acid, comprising a filter device body 1, a fixing component 2, a connecting plate 3, a primary filter plate 6, and a secondary filter plate 7. Two mounting grooves 8 are formed on both the upper and lower sides of the inner wall of the filter device body 1. A support frame 4 is inserted into the inner wall of each pair of mounting grooves 8. Two through grooves 10 are formed on the right side of the filter device body 1. Multiple fitting grooves 9 are formed on both the upper and lower sides of the inner wall of the through grooves 10. Multiple rubber protrusions 18 are installed on both the upper and lower sides of the right side of the support frame 4. The through grooves 10 and the mounting grooves 8 are interconnected, allowing for... To facilitate pulling the support frame 4 out to the right and detaching it from the filter device body 1, the upper and lower rubber protrusions 18 are engaged with the inner wall of the fitting groove 9. The fit between the rubber protrusions 18 and the fitting groove 9 increases the sealing performance of the support frame 4 after insertion. The upper and lower support frames 4 are installed between the upper and lower support frames 4 and the right side connecting plate 3, and the right side of the support frame 4 is inserted into the inner wall of the through groove 10 for subsequent disassembly and use. The primary filter plate 6 is installed on the inner wall of the upper support frame 4, and the secondary filter plate 7 is installed on the inner wall of the lower support frame 4, so that the primary filter plate 6 and the secondary filter plate 7 can be easily maintained after the support frame 4 is removed.

[0026] First, pull the right connecting plate 3 to the right, causing the two support frames 4 on its left side to slide along the inner wall of the mounting groove 8. At the same time, the multiple rubber protrusions 18 on the right side of the support frame 4 will disengage from the fitting groove 9. After the support frame 4 is completely disengaged from the filter device body 1, the primary filter plate 6 and the secondary filter plate 7 can be maintained. After that, insert the support frame 4 into the inner wall of the through groove 10 and gradually insert it into the inner wall of the mounting groove 8 to the left. When the right side of the support frame 4 returns to the inner wall of the through groove 10, the multiple rubber protrusions 18 on its right side will be locked with the fitting groove 9 to increase the sealing after insertion, thereby facilitating subsequent maintenance and use, and improving the performance of the filter device body 1.

[0027] Example 2: Based on Example 1, in order to enable the support frame 4 to be pulled out without the need for operators to use tools, the upper and lower sides of the inside of the right connecting plate 3 are provided with sliding grooves 13. The inner wall of the sliding groove 13 is installed with a limiting plate 12. A limiting plate 11 is installed on one side of the limiting plate 12, and an elastic element 16 is installed on the other side. Connecting ropes 14 are installed on the adjacent sides of the upper and lower limiting plates 12. A knob 15 is rotatably connected to the middle of the right connecting plate 3. A limiting groove 21 is provided on the adjacent sides of the two right fixing parts 2. The upper and lower elastic elements 14 are provided with a limiting groove 21. The adjacent sides of the 6 are installed on the inner wall of the slide groove 13, so that the elastic force of the elastic element 16 can be used to easily drive the limiting plate 11 to reset. The opposite sides of the upper and lower limiting plates 11 pass through the right connecting plate 3 and are inserted into the inner wall of the limiting groove 21. The cooperation between the limiting plate 11 and the limiting groove 21 can lock the right connecting plate 3 and the two right fixing elements 2 for subsequent disassembly and use. The adjacent ends of the upper and lower connecting ropes 14 are installed between the knob 15, so that the two connecting ropes 14 can be used to pull the upper and lower limiting plates 11 to move towards each other.

[0028] First, turn knob 15 to drive the two connecting ropes 14 to wrap around its outer side, thereby pulling the upper and lower limit plates 12 to move towards each other along the inner wall of the slide groove 13, and causing the limit plate 11 to disengage from the limit groove 21. At this time, the movement of the limit plate 12 will push the elastic element 16, causing it to be compressed in the inner wall of the slide groove 13. Then, the right connecting plate 3 can be pulled to the right to maintain the primary filter plate 6 and the secondary filter plate 7. After that, insert the support frame 4 into the inner wall of the through groove 10, and gradually insert it into the inner wall of the mounting groove 8 to the left. At the same time, release knob 15, thereby using the elastic force of the elastic element 16 to push the upper and lower limit plates 12 to move in opposite directions, and causing one side of the limit plate 11 to be inserted into the inner wall of the limit groove 21, thereby continuing to lock the right connecting plate 3 and the two right fixing parts 2 for subsequent maintenance. Thus, the primary filter plate 6 and the secondary filter plate 7 can be maintained without the need for operators to use additional tools.

[0029] Example 3: Based on Example 2, in order to facilitate the replacement of a single filter plate, insertion slots 17 are provided on both the front and rear sides of the support frame 4. Insertion plates 5 are installed on the inner walls of the insertion slots 17, and a retaining ball 20 is installed on the right side of the insertion plates 5. Two retaining slots 19 are provided on the right side of the inner wall of the support frame 4. The two upper insertion plates 5 are installed between the primary filter plate 6 and the two lower insertion plates 5 are installed between the secondary filter plate 7, thereby facilitating the replacement of the primary filter plate 6 or the secondary filter plate 7 individually and reducing the replacement cost. The retaining ball 20 is inserted into the inner wall of the retaining slot 19, thereby using the retaining ball 20 to assemble the primary filter plate 6 and the secondary filter plate 7 between the support frame 4 respectively, so as to facilitate subsequent individual replacement.

[0030] When it is necessary to replace the primary filter plate 6 or the secondary filter plate 7, first turn the knob 15 to pull the two support frames 4 to the right, then pull the primary filter plate 6 or the secondary filter plate 7 to the left, and drive the plug plates 5 on both sides to slide to the left along the inner wall of the plug groove 17. At the same time, drive the retaining ball 20 on the right side of the plug plate 5 to disengage from the retaining groove 19, so as to facilitate the replacement of the primary filter plate 6 or the secondary filter plate 7 separately, thereby reducing the replacement cost. After completion, use the plug plate 5 to fit the primary filter plate 6 or the secondary filter plate 7 between the plug plate 5 and the plug groove 17, and drive the retaining ball 20 to engage with the inner wall of the retaining groove 19, thereby resetting the primary filter plate 6 or the secondary filter plate 7. Then, the support frame 4 can be reset to improve the filtration effect of the filter device body 1.

[0031] In actual use, first turn the knob 15 to drive the two connecting ropes 14 to wrap around its outer side, thereby pulling the upper and lower limit plates 12 to move towards each other along the inner wall of the slide groove 13, and driving the limit plate 11 to disengage from the limit groove 21. At this time, the movement of the limit plate 12 will squeeze the elastic element 16, causing it to be in a compressed state on the inner wall of the slide groove 13. Then, the right connecting plate 3 can be pulled to the right, and the two support frames 4 on its left side can slide along the inner wall of the mounting groove 8. At the same time, the multiple rubber protrusions 18 on the right side of the support frame 4 will disengage from the fitting groove 9. After the support frame 4 is completely disengaged from the filter device body 1, the primary filter plate 6 and the secondary filter plate 7 can be connected. After maintenance is completed, insert the support frame 4 into the inner wall of the through groove 10 and gradually insert it into the inner wall of the mounting groove 8 to the left. When the right side of the support frame 4 is reset to the inner wall of the through groove 10, the multiple rubber protrusions 18 on its right side will be locked between the fitting groove 9 to increase the sealing after insertion. At the same time, loosen the knob 15, thereby using the elastic force of the elastic element 16 to push the upper and lower limit plates 12 to move in opposite directions, and drive one side of the limit plate 11 to insert into the inner wall of the limit groove 21, thereby continuing to lock the right connecting plate 3 between the two right fixing parts 2 for subsequent maintenance and use, thereby improving the use effect of the filter device body 1.

[0032] When it is necessary to replace the primary filter plate 6 or the secondary filter plate 7, first turn the knob 15 to pull the two support frames 4 to the right, then pull the primary filter plate 6 or the secondary filter plate 7 to the left, and drive the plug plates 5 on both sides to slide to the left along the inner wall of the plug groove 17. At the same time, drive the retaining ball 20 on the right side of the plug plate 5 to disengage from the retaining groove 19, so as to facilitate the replacement of the primary filter plate 6 or the secondary filter plate 7 separately, thereby reducing the replacement cost. After completion, use the plug plate 5 to fit the primary filter plate 6 or the secondary filter plate 7 between the plug plate 5 and the plug groove 17, and drive the retaining ball 20 to engage with the inner wall of the retaining groove 19, thereby resetting the primary filter plate 6 or the secondary filter plate 7. Then, the support frame 4 can be reset to improve the filtration effect of the filter device body 1.
