[0001] This utility model relates to the technical field of sludge recycling, specifically to a calcium fluoride sludge recycling device. Background Technology

[0002] Calcium fluoride sludge is a byproduct of wastewater treatment in industries such as fluorochemicals, semiconductors, and photovoltaics. By recycling calcium fluoride sludge and converting it into high-value products such as smelting auxiliaries, the recycling of fluorine resources can be achieved, while reducing the environmental burden.

[0003] In related technologies, when recovering calcium fluoride sludge, it is necessary to dilute the sludge with chemicals before transporting it to the subsequent purification process for purification chemical reactions. In practice, due to the high viscosity of calcium fluoride sludge, it is difficult to fully mix the sludge and chemicals. When using a pump to transport the sludge, this can easily lead to pipe blockage, affecting the subsequent purification operations of the calcium fluoride sludge. Utility Model Content

[0030] The embodiments of this utility model are described in detail below, with examples of the embodiments shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0031] like Figures 1 to 3 As shown, the calcium fluoride sludge recovery device 100 of this utility model embodiment includes a mixing tank 1 and a plurality of mixing components 2. The mixing tank 1 has a discharge port for discharging calcium fluoride sludge. The plurality of mixing components 2 are all disposed in the mixing tank 1 and arranged at intervals. The mixing component 2 includes a mixing shaft 21 and mixing blades 22. The mixing shaft 21 is rotatably connected to the tank wall of the mixing tank 1, and the mixing blades 22 are connected to the mixing shaft 21.

[0032] The calcium fluoride sludge recovery device 100 of this utility model puts calcium fluoride sludge and reagents into a mixing tank 1. Multiple mixing components 2 can fully mix the calcium fluoride and sludge, achieving sufficient dilution of the calcium fluoride sludge. The fully mixed calcium fluoride sludge has good fluidity and can be transported by a pump body 31, which can reduce the risk of clogging and facilitate subsequent purification operations, thereby improving the effect and efficiency of subsequent treatment processes.

[0033] Specifically, such as Figure 1 As shown, the calcium fluoride sludge recovery device 100 also includes a pump body 31. The inlet of the pump body 31 is connected to the discharge port of the mixing box 1 through a pipeline, and the outlet of the pump body 31 is connected to the equipment of the next process through a pipeline. The pump body 31 can be used to transport the uniformly mixed calcium fluoride sludge to the next process.

[0034] The mixing tank 1 is a rectangular box 11. The pump body 31 of the mixing tank 1 is installed on the ground or other installation platform via the base 3. The discharge port is arranged on the side wall of the mixing tank 1 and close to the bottom of the mixing tank 1 so as to drain the calcium fluoride sludge in the mixing tank 1. The top wall of the mixing tank 1 has a chemical inlet 121, which makes it easier to control the dosage of the added chemical.

[0035] In some embodiments, the mixing bin 1 includes a bin body 11 and a bin cover 12, the bin body 11 being slidably connected to the bin body 12 so that the mixing bin 1 can switch between an open state and a closed state.

[0036] Switching the mixing tank 1 to the open state allows calcium fluoride sludge to be added into the tank 11. After the calcium fluoride sludge is added, switching the mixing tank 1 to the closed state prevents the mixture of calcium fluoride sludge and reagent from overflowing during the mixing process.

[0037] In some embodiments, the calcium fluoride sludge recovery device 100 further includes a support frame 4 and a drive component. The support frame 4 is connected to the housing 11, and the drive component is connected to the support frame 4. The drive component is used to drive the housing cover 12 to slide relative to the housing 11.

[0038] Optionally, the driving component is a hydraulic cylinder 51.

[0039] In some embodiments, the calcium fluoride sludge recovery device 100 further includes a first sliding part and a second sliding part, the first sliding part and the second sliding part are slidably engaged, the first sliding part is connected to the support frame 4, and the second sliding part is connected to the box cover 12.

[0040] In some embodiments, the support frame 4 has a sliding hole 411, and a sliding rod 52 is connected to the cover 12. The sliding rod 52 passes through the sliding hole 411 and slides in cooperation with the sliding hole 411. The sliding hole 411 forms a first sliding part, and the sliding rod 52 forms a second sliding part.

[0041] Specifically, such as Figure 1 and Figure 2 As shown, the support frame 4 includes a horizontally extending crossbar 41 and two vertically extending vertical bars 42. The crossbar 41 is located on the upper side of the mixing box 1 and is at a certain distance from the mixing box 1. The two vertical bars 42 are respectively attached to the outer sides of the two relatively parallel side walls of the mixing box 1 and are fixedly connected to the side walls of the mixing box 1. The two vertical bars 42 are respectively connected to the two ends of the crossbar 41, thereby forming a U-shaped support frame 4. The support frame 4 is installed on the upper side of the mixing box 1.

[0042] The cylinder body of the hydraulic cylinder 51 is fixedly connected to the crossbar 41 of the support frame 4. The piston rod of the hydraulic cylinder 51 passes vertically downward through the crossbar 41 and is fixedly connected to the top of the box cover 12. This allows the box cover 12 to slide up and down, so that the mixing box 1 switches between the open and closed states.

[0043] Two sliding holes 411 are arranged on the crossbar 41 and are symmetrically arranged on both sides of the hydraulic cylinder 51. There are two sliding rods 52, which pass through the two sliding holes 411 respectively and slide in cooperation with the sliding holes 411. The lower ends of the two sliding rods 52 are fixedly connected to the cover 12, thereby improving the stability of the cover 12 sliding up and down.

[0044] In some embodiments, multiple mixing components 2 are connected to the box cover 12.

[0045] Multiple mixing components 2 are connected to the box cover 12. When the box cover 12 is opened upward, it can move multiple mixing components 2, which facilitates the assembly, maintenance and disassembly of multiple mixing components 2.

[0046] Optionally, the number of mixing components 2 is four.

[0047] In some embodiments, the mixing assembly 2 further includes a power component for driving the mixing shaft 21 to rotate, the power component having a power shaft, and the mixing shaft 21 being detachably connected to the power shaft.

[0048] The mixing shaft 21 is detachably connected to the power shaft. When the mixing shaft 21 or the mixing blade 22 is damaged, it is easy to remove the mixing shaft 21 for inspection and replacement.

[0049] Optionally, the power component is a motor 6.

[0050] In some embodiments, the power shaft has a first insertion portion and the mixing shaft 21 has a second insertion portion, and the first insertion portion and the second insertion portion are inserted into each other; the mixing assembly 2 further includes a locking assembly 7, which is connected to the first insertion portion and the second insertion portion, so as to drive the mixing shaft 21 to rotate using the power shaft.

[0051] In some embodiments, the power shaft includes a plug-in rod segment 61 with a polygonal cross-section, and the mixing shaft 21 has a plug-in hole 211 with a cross-section matching the cross-section of the plug-in rod segment 61, allowing the plug-in rod segment 61 to be inserted into the plug-in hole 211; wherein the plug-in rod segment 61 forms a first plug-in portion, and the plug-in hole 211 forms a second plug-in portion.

[0052] In some embodiments, the locking assembly 7 includes a locking rod 71 and an elastic member. The insertion rod segment 61 has a first locking hole 611, and the wall of the insertion hole 211 has a second locking hole 212. When the insertion rod segment 61 is inserted into the insertion hole 211, the first locking hole 611 and the second locking hole 212 are aligned. The locking rod 71 is connected to the mixing shaft 21 and slidably passes through the second locking hole 212. The elastic member is used to apply a spring force to the locking rod 71 so that the locking rod 71 tends to slide towards the insertion rod segment 61.

[0053] Optionally, the elastic element is a spring 72.

[0054] Specifically, such as Figure 2 and Figure 3 As shown, the mixing shaft 21 extends vertically, and there are multiple mixing blades 22. The multiple mixing blades 22 are divided into two groups, and the two groups of mixing blades 22 are arranged opposite each other along the radial direction of the mixing shaft 21. The multiple mixing blades 22 in the same group are arranged at intervals along the extension direction of the mixing shaft 21 and are fixedly connected to the mixing shaft 21. Thus, by using the multiple mixing blades 22 in conjunction with the mixing shaft 21, the calcium fluoride sludge and the reagent can be fully stirred, so that the calcium fluoride sludge and the reagent are fully mixed.

[0055] The motor 6 is located on the upper side of the cover 12 and is fixedly connected to the cover 12. The power shaft of the motor 6 passes through the cover 12 and is connected to the upper end of the mixing shaft 21. The power shaft includes a shaft section 62 and a plug-in rod section 61. The shaft section 62 is arranged close to the motor 6 body. The cross-section of the plug-in rod section 61 is rectangular. The upper end face of the mixing shaft 21 has the aforementioned plug-in hole 211. The cross-section of the plug-in hole 211 is also rectangular, and its size matches the size of the plug-in rod section 61, so that the plug-in rod section 61 can be inserted into the plug-in hole 211 to realize the connection between the mixing shaft 21 and the power shaft, and drive the mixing shaft 21 to rotate using the power shaft.

[0056] The first locking hole 611 is radially through the power shaft, and the second locking hole 212 is radially through the mixing shaft 21. The locking assembly 7 includes a locking rod 71 and a spring 72. The locking rod 71 is connected to the mixing shaft 21. The locking rod 71 includes a rod body and a stop. The rod body slides through the second locking hole 212, and the stop is connected to the end of the rod body so that the operator can manually control the sliding of the locking rod 71. The spring 72 is fitted onto the rod body. One end of the spring 72 is fixedly connected to the stop, and the other end is fixedly connected to the outer side of the mixing shaft 21. The spring 72 applies an elastic tension to the stop, so that the locking rod 71 has a tendency to slide inward along the radial direction of the mixing shaft 21.

[0057] When assembling the mixing shaft 21 and the power shaft, pull the locking rod 71 outward, and then insert the connecting rod section 61 into the connecting hole 211. After insertion, the first locking hole 611 and the second locking hole 212 are aligned. Release the locking rod 71, and under the action of the spring 72, the locking rod 71 can automatically insert into the first locking hole 611, thereby realizing a stable connection between the mixing shaft 21 and the power shaft, preventing the mixing shaft 21 from disengaging from the power shaft during operation, and improving the stability of the mixing process.

[0058] Optionally, such as Figure 3 As shown, a rubber pad 8 is provided between the shaft section 62 of the power shaft and the mixing shaft 21, and the rubber pad 8 is fitted onto the plug-in rod section 61; this can further improve the stability of the mixing shaft 21 during the mixing operation.

[0059] In this embodiment of the calcium fluoride recovery device, the calcium fluoride sludge is first put into the mixing tank 1, and the tank cover 12 is switched to the closed state by the hydraulic cylinder 51 to prevent the mixture of calcium fluoride sludge and reagent from overflowing during the mixing process. Then, the chemical reagent is injected into the mixing tank 1 through the reagent port 121, and at the same time, the motors 6 of multiple mixing components 2 are started. The motors 6 drive the mixing shaft 21 to rotate, so that the sludge and reagent are fully mixed and in contact, promoting the chemical reaction, improving the uniformity and thoroughness of the reaction, and facilitating the subsequent purification operation. After the mixing is completed, the diluted calcium fluoride sludge is transported to the next process by the pump body 31.
