[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Example 1:
[0027] Please see Figure 1-7 This is the first embodiment of the present utility model, which provides a technical solution: a waste hydrochloric acid recycling and treatment device, including a treatment box 1 and a filter screen 16. A fixing block 8 is fixedly installed on one side of the treatment box 1, and a motor 9 is fixedly installed on one side of the fixing block 8. A lead screw 10 is fixedly connected to the shaft of the motor 9. A sliding groove 81 is opened on the top surface of the fixing block 8. The lead screw 10 is rotatably connected to the sliding groove 81. A support frame 12 is slidably connected in the sliding groove 81. A threaded sleeve 121 is embedded in the bottom of the support frame 12. The threaded sleeve 121 is threadedly connected to the lead screw 10. A cylinder 13 is fixedly installed on the top surface of the support frame 12. A connecting rod 14 is fixedly connected to the output end of the piston rod of the cylinder 13. A cover plate 15 is fixedly installed at the bottom end of the connecting rod 14. Multiple positioning ports 151 are opened on the top surface of the cover plate 15. Multiple fixing rods 17 are fixedly connected to the top surface of the filter screen 16. The fixing rods 17 are slidably connected to the positioning ports 151. A limiting port 171 is opened on one side of the top of the fixing rod 17.
[0028] A fixing bracket 18 is fixedly connected to both ends of the top surface of the cover plate 15. A threaded hole 181 is opened on the top surface of the fixing bracket 18. The threaded hole 181 is internally threaded to the threaded part of the threaded rod 19. A rotating block 20 is fixedly connected to the top end of the threaded rod 19. Multiple sliding plates 21 are slidably connected to the top surface of the cover plate 15. There are two sliding plates 21. Pulling plates 22 are fixedly connected to the top surface of the two sliding plates 21 respectively. Limiting square rods 23 are fixedly connected to the two ends of the two sliding plates 21 on the side away from each other. The limiting square rods 23 are slidably connected to the limiting port 171. A positioning hole 211 is opened on the top surface of the sliding plate 21. The bottom smooth rod of the threaded rod 19 contacts the positioning hole 211. A limiting slider 212 is fixedly connected to the bottom surface of the sliding plate 21. A limiting groove 152 is opened at both ends of the top surface of the cover plate 15 respectively. The limiting slider 212 is slidably connected to the limiting groove 152. When installing the filter screen 16, the fixing rod 17 on the filter screen 16 can be slid into the positioning port 151 of the cover plate 15. When the limiting plate 172 on the fixing rod 17 contacts the bottom surface of the cover plate 15, the movement stops. By pulling the plate 22, the sliding plate 21 and the limiting rod 23 are moved, so that the limiting rod 23 slides into the limiting port 171 of the fixing rod 17, which can limit the fixing rod 17. After the sliding plate 21 moves to the appropriate position, the threaded rod 19 can be rotated by rotating the rotating block 20, so that the smooth part of the threaded rod 19 enters the positioning hole 211 on the sliding plate 21, which can limit and fix the sliding plate 21 and the limiting rod 23, thereby limiting and fixing the fixing rod 17 and the filter screen 16.
[0029] Example 2:
[0030] Please see Figure 1-7 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The limiting square rod 23 is slidably connected to the top surface of the cover plate 15, and multiple protrusions 201 are fixed to the outer surface of the rotating block 20 to facilitate the rotation of the rotating block 20.
[0031] A limiting plate 172 is fixedly connected to one side of the fixed rod 17. The top surface of the limiting plate 172 contacts the cover plate 15, which can limit the movement range of the fixed rod 17 when the filter screen plate 16 is installed, making it easier to determine the sliding position of the fixed rod 17.
[0032] A limiting ring plate 191 is fixed to the outer surface of the smooth part of the threaded rod 19. The limiting ring plate 191 contacts the top surface of the sliding plate 21, which can limit the movement range of the threaded rod 19, making it easier to determine the rotation range of the rotating block 20 and preventing the threaded rod 19 from falling off the fixing frame 18.
[0033] Multiple support legs 2 are fixed to the bottom of the treatment box 1. An observation window 5 is provided on one side of the treatment box 1 to facilitate observation of the accumulation of impurities on the filter screen 16. An inlet pipe 3 is fixedly installed inside one side of the treatment box 1, and an outlet pipe 4 is fixedly installed inside the bottom of the treatment box 1. A guide block 6 is fixedly installed inside the bottom of the treatment box 1 to facilitate the flow of filtered waste liquid to the outlet pipe 4. Support blocks 7 are fixedly installed around the inside of the treatment box 1 to support the filter screen 16. During the filtration of waste liquid, the drive motor 9 drives the lead screw 10 to rotate, which moves the support frame 12 until one side of the support frame 12 contacts the inside of the slide groove 81 and stops moving, so that the filter screen 16 is directly above the treatment box 1. The drive cylinder 13 drives the cover plate 15, the fixing rod 17, the filter screen 16, etc. to move down, so that the bottom surface of the filter screen 16 contacts the support block 7 and the cover plate 15 contacts the top surface of the treatment box 1.
[0034] Limiting blocks 11 are fixedly connected to both sides of the bottom of the support frame 12, and limiting grooves 811 are opened on both sides of the slide groove 81. The limiting blocks 11 are slidably connected to the limiting grooves 811 to improve the stability of the movement of the support frame 12.
[0035] Example 3:
[0036] Please see Figure 1-7 This is the third embodiment of the present invention, based on the above two embodiments. In actual use, the waste liquid enters the treatment tank 1 through the inlet pipe 3, is filtered by the filter screen 16, and is discharged through the outlet pipe 4. When the filter screen 16 needs to be cleaned, the cylinder 13 is connected to an external power source. By starting the cylinder 13, the cover plate 15, the fixing rod 17, and the filter screen 16 are moved upward, so that the filter screen 16 is detached from the treatment tank 1 and is higher than the top of the treatment tank 1. The motor 9 is connected to an external power source. By starting the motor 9, the lead screw 10 is rotated, which in turn rotates the support frame 12, the cylinder 13, the cover plate 15, and the filter screen 16. The filter screen 16 moves horizontally backward to a suitable position for cleaning. When the filter screen 16 needs to be disassembled, replaced, or maintained, the rotating block 20 can be rotated to drive the threaded rod 19 to rotate, causing the smooth part of the threaded rod 19 to disengage from the positioning hole 211 of the sliding plate 21, thus releasing the limitation on the sliding plate 21. The sliding plate 21 can be slid by pulling the plate 22, and the limiting rod 23 moves accordingly, causing the limiting rod 23 to disengage from the limiting port 171 of the fixed rod 17, thus releasing the limitation on the fixed rod 17. The fixed rod 17 and the filter screen 16 can then be completely disassembled for replacement or maintenance.
[0037] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
