Description

Technical Field

[0001] This utility model relates to the field of ammonium persulfate mother liquor recovery technology, and in particular to an iron removal filtration device for ammonium persulfate mother liquor. Background Technology

[0002] Ammonium persulfate mother liquor is the solution containing ammonium persulfate and other impurities remaining after crystallization and separation during the production or use of ammonium persulfate. Industrially, ammonium persulfate mother liquor has certain recycling value.

[0003] In practice, when recovering ammonium persulfate mother liquor, it is necessary to first remove iron and filter the ammonium persulfate mother liquor. In the prior art, when removing iron from ammonium persulfate mother liquor, most of them directly use magnetic plates, such as the ammonium persulfate mother liquor iron removal and filtration device disclosed in the utility model authorized announcement number CN219539674U.

[0004] While the above methods can remove iron from ammonium persulfate mother liquor, the removed iron impurities will be directly adsorbed on the surface of the magnetic plate, making subsequent cleaning difficult. In addition, relying solely on the contact between the ammonium persulfate mother liquor and the magnetic plate during its flow to remove iron often results in insufficient iron removal efficiency.

[0005] Therefore, it is necessary to invent an iron removal filtration device for ammonium persulfate mother liquor to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an iron removal filtration device for ammonium persulfate mother liquor, which can more conveniently clean and output iron impurities. At the same time, the four magnetic plates can rotate continuously and contact the ammonium persulfate mother liquor through the cross rotating seat, resulting in higher iron removal efficiency. This solves the problem mentioned in the background art that the removed iron impurities are directly adsorbed on the surface of the magnetic plates, making subsequent cleaning difficult. In addition, relying solely on the contact between the ammonium persulfate mother liquor and the magnetic plates during the flow of iron removal often results in insufficient iron removal efficiency.

[0007] According to one aspect of this disclosure, the following technical solution is provided: an iron removal filtration device for ammonium persulfate mother liquor, comprising:

[0008] An ammonium persulfate mother liquor containing assembly, wherein the ammonium persulfate mother liquor containing assembly is used to contain ammonium persulfate mother liquor to be iron removed;

[0009] A filtration assembly for filtering ammonium persulfate mother liquor after iron removal; and

[0010] A lifting-type iron removal assembly includes a motor fixedly installed at the center of the bottom of an upper container. The output shaft of the motor extends into the interior of the upper container and is fixedly connected to a cross-shaped rotating seat. The top of the cross-shaped rotating seat has a cross-shaped receiving groove and an integrally formed protrusion on its outer top. The lifting-type iron removal assembly also includes an electric push rod fixedly installed at the center of the top of the upper container. The output shaft of the electric push rod extends into the interior of the upper container, and a cross plate is rotatably sleeved at the bottom of its output shaft through a bearing. Four magnetic plates are evenly fixedly installed at the bottom of the cross plate, and the four magnetic plates slide vertically against the inner side of the cross-shaped receiving groove.

[0011] According to at least one embodiment of the ammonium persulfate mother liquor iron removal filtration device of the present disclosure, the ammonium persulfate mother liquor containing assembly includes an upper container, and an ammonium persulfate mother liquor inlet pipe is fixedly and throughly disposed on the left side of the upper container.

[0012] According to at least one embodiment of the ammonium persulfate mother liquor iron removal filtration device of the present disclosure, a connecting pipe is fixedly provided through the right side of the upper container, a first valve is provided on the connecting pipe, and a connecting frame is fixedly sleeved on the bottom of the outer side of the upper container.

[0013] According to at least one embodiment of the ammonium persulfate mother liquor iron removal filtration device, the filtration assembly includes a lower container that is connected to a connecting pipe and fixedly disposed inside a connecting frame, and a support frame is fixedly sleeved on the bottom outer side of the lower container.

[0014] According to at least one embodiment of the ammonium persulfate mother liquor iron removal filtration device of the present disclosure, an ammonium persulfate mother liquor output pipe is fixedly and penetrated through the bottom of the lower container, and a second valve is provided on the ammonium persulfate mother liquor output pipe.

[0015] According to at least one embodiment of the ammonium persulfate mother liquor iron removal filtration device of the present disclosure, a support ring is fixedly provided on the inner side of the lower container, and a filter screen plate that slides and fits against the inner wall of the lower container is placed on the top of the support ring.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] This invention features a lifting-type iron removal assembly. When removing iron from the ammonium persulfate mother liquor inside the upper container, a motor drives a cross-shaped rotating seat to rotate slowly. As the rotating seat rotates, it drives four magnetic plates to rotate synchronously through a cross-shaped receiving groove. This causes iron impurities in the ammonium persulfate mother liquor to be adsorbed onto the surface of the rotating seat. After iron removal is complete, the ammonium persulfate mother liquor is output through a connecting pipe. Then, an electric push rod moves the cross plates upwards, causing the four magnetic plates to move synchronously upwards within the cross-shaped receiving groove. Iron impurities outside the rotating seat are blocked by a protrusion at the top of the outer side of the rotating seat, preventing them from moving upwards with the magnetic plates. Once the magnetic plates reach the top of the inner side of the cross-shaped receiving groove, the iron impurities outside the rotating seat are no longer attracted by the magnetism and fall to the bottom of the upper container. Compared to existing technologies, this invention allows for more convenient cleaning and output of iron impurities. Furthermore, the four magnetic plates can continuously rotate and contact the ammonium persulfate mother liquor through the rotating seat, resulting in higher iron removal efficiency.

[0027] Figure 1 This is a schematic diagram of the overall structure of an iron removal filtration device for ammonium persulfate mother liquor according to one embodiment of the present disclosure.

[0028] Figure 2 This is a schematic diagram of the structure of the ammonium persulfate mother liquor containing component 1 and the lifting iron removal component 3 of an ammonium persulfate mother liquor iron removal filtration device according to one embodiment of the present disclosure.

[0029] Figure 3 This is a schematic diagram of the filter assembly 2 of an ammonium persulfate mother liquor iron removal filtration device according to one embodiment of the present disclosure.

[0030] like Figures 1-3 As shown, the ammonium persulfate mother liquor iron removal filtration device disclosed herein consists of three parts: an ammonium persulfate mother liquor containing component 1, a filtration component 2, and a lifting iron removal component 3, forming an integrated processing flow of "mother liquor input → iron removal → filtration → output". The ammonium persulfate mother liquor containing component 1 provides space for the iron removal reaction, the lifting iron removal component 3 achieves efficient iron removal and impurity cleaning, and the filtration component 2 performs deep purification of the mother liquor after iron removal. The three components work together to ensure the purity of the recovered ammonium persulfate mother liquor.

[0031] like Figure 2 As shown in this disclosure, the ammonium persulfate mother liquor containing assembly 1 includes an upper container 11. An ammonium persulfate mother liquor input pipe 12 is fixedly installed through the left side of the upper container 11, and a connecting pipe 13 is fixedly installed through the right side of the upper container 11. A first valve is installed on the connecting pipe 13. A connecting frame 14, made of high-strength alloy material, is fixedly sleeved on the bottom of the outer side of the upper container 11 and fixed to the lower container 21 of the filter assembly 2. This not only supports the weight of the upper container 11 but also ensures the coaxiality of the two containers and avoids leakage during the transportation of the mother liquor.

[0032] Therefore, the ammonium persulfate mother liquor to be de-ironized is input into the upper container 11 through the ammonium persulfate mother liquor input pipe 12. After the iron removal of the ammonium persulfate mother liquor is completed, the first valve on the connecting pipe 13 is opened, so that the iron-removed ammonium persulfate mother liquor is input into the lower container 21 through the connecting pipe 13.

[0033] Additionally, an inlet pipe and an outlet pipe (not shown) are fixedly installed through the back of the upper container 11. A third valve is installed on the outlet pipe. In the initial state, the first valve on the connecting pipe 13 and the third valve on the outlet pipe on the back of the upper container 11 are both closed, so that after the iron impurities fall to the bottom of the inner cavity of the upper container 11, cleaning water is introduced into the upper container 11 through the inlet pipe. Subsequently, the cleaning water carries the iron impurities out through the drain pipe.

[0034] like Figure 3 As shown, in a preferred embodiment, the filter assembly 2 includes a lower container 21 that is connected to the connecting pipe 13 and fixedly disposed inside the connecting frame 14. A support frame 22 is fixedly sleeved on the bottom of the lower container 21. An ammonium persulfate mother liquor output pipe 23 is fixedly disposed through the bottom of the lower container 21. A second valve is disposed on the ammonium persulfate mother liquor output pipe 23. A support ring 24 is fixedly disposed inside the lower container 21. A filter screen plate 25 that slides and fits against the inner wall of the lower container 21 is placed on the top of the support ring 24.

[0035] Therefore, after the ammonium persulfate mother liquor is de-ironized, it is fed into the lower container 21 through the connecting pipe 13, then passes through the filter screen 25 under gravity and is filtered by the filter screen 25, and finally is output through the ammonium persulfate mother liquor output pipe 23.

[0036] like Figure 2As shown in this disclosure, the lifting-type iron removal assembly 3 includes a motor 31 fixedly installed at the center of the bottom of the upper container 11. A servo motor is selected, with a speed adjustable to 5-10 r / min. The output shaft of the motor 31 extends into the upper container 11 and is fixedly connected to a cross-shaped rotating seat 32. The top of the cross-shaped rotating seat 32 has a cross-shaped receiving groove 33, and the outer top has an integrally formed protrusion. The lifting-type iron removal assembly 3 also includes an electric push rod 34 fixedly installed at the center of the top of the upper container 11. The output shaft of the electric push rod 34 extends into the upper container 11 and its output... A cross plate 35 is mounted on the bottom of the output shaft via a bearing. Four magnetic plates 36 are evenly fixed on the bottom of the cross plate 35. The magnetic plates 36 are made of neodymium iron boron strong magnetic material and have an anti-corrosion coating. Their magnetic force is transmitted to the outside through the cross rotating seat 32. The cross rotating seat 32 is made of stainless steel and does not shield the magnetic force. The four magnetic plates 36 slide and adhere to the inside of the cross receiving groove 33 in the vertical direction. After processing 500L of mother liquor, the magnetic force of the magnetic plates 36 needs to be checked (by testing the number of iron nails adsorbed). If the magnetic force weakens, they need to be replaced in time to ensure iron removal efficiency.

[0037] Therefore, to facilitate the removal of iron from the ammonium persulfate mother liquor inside the upper container 11, the motor 31 drives the cross-shaped rotating seat 32 to rotate slowly. As the cross-shaped rotating seat 32 rotates, it drives the four magnetic plates 36 to rotate synchronously through the cross-shaped receiving groove 33, thereby adsorbing iron impurities in the ammonium persulfate mother liquor onto the surface of the cross-shaped rotating seat 32. After the iron removal of the ammonium persulfate mother liquor is completed, the iron-removed ammonium persulfate mother liquor is output through the connecting pipe 13. Subsequently, the electric push rod 34 drives the cross plate 35 to move upwards. As the cross plate 35 moves upwards, it drives the four magnetic plates 36 to rotate within the cross-shaped receiving groove 33. As the magnetic plate 36 moves upward synchronously, the iron impurities on the outside of the cross-shaped rotating seat 32 are blocked by the protrusion at the top of the outside of the cross-shaped rotating seat 32, and thus cannot move upward synchronously with the magnetic plate 36. After the magnetic plate 36 moves to the top of the inside of the cross-shaped receiving groove 33, the iron impurities on the outside of the cross-shaped rotating seat 32 are no longer attracted by the magnetic force, and then fall into the bottom of the upper container 11. Compared with the prior art, this utility model can clean and output iron impurities very conveniently. At the same time, the four magnetic plates 36 can continue to rotate and contact the ammonium persulfate mother liquor through the cross-shaped rotating seat 32, resulting in higher iron removal efficiency.

[0039] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
