[0002] Ammonium sulfate is produced during the production of solar cells. Ammonium sulfate wastewater can cause great harm to the environment. Before discharge, the wastewater containing ammonium sulfate needs to be transported to a regulating tank for treatment.

[0003] Medium and large solar cell manufacturers discharge large volumes of ammonium sulfate wastewater, necessitating frequent replacement of the filter screens within the filter devices attached to the regulating tank inlet pipes. Currently, most filter devices installed on regulating tank inlet pipes utilize flange connections, making installation and removal very inconvenient. Installation is particularly challenging, as one person must lift the filter and align it with the pipe opening while another tightens the bolts.

[0004] Therefore, in view of the above technical problems, it is necessary to provide a pH regulating tank for treating ammonium sulfate wastewater in solar cell processing.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

[0029] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0030] like Figure 1As shown, the pH adjustment tank for treating ammonium sulfate wastewater in solar cell processing in one embodiment of the present invention includes a tank body 1, an inlet pipe 11 is integrally formed on the tank body 1, and a water supply pipe 12 is provided at one end of the water inlet pipe 11 away from the tank body 1. A filtering device is installed between the tank body 1 and the water supply pipe 12, and the filter screen in the filtering device can filter the ammonium sulfate wastewater.

[0031] like Figures 1 to 4 As shown, the filter device includes a first filter body 2 and a second filter body 3. One end of the second filter body 3 is welded to the outer wall of the upper half of the water inlet pipe 11, and the end of the second filter body 3 away from the water inlet pipe 11 is welded to the outer wall of the upper half of the water supply pipe 12. A third limiting strip 34 and a fourth limiting strip 35 are integrally formed on the inner wall of the second filter body 3. The first filter body 2 is detachably mounted on the lower end surface of the second filter body 3. A soft rubber ring is bonded to the inner wall of the first filter body 2. A first limiting strip 22 that matches the third limiting strip 34 and a second limiting strip 23 that matches the fourth limiting strip 35 are integrally formed within the first filter body 2. A filter screen is inserted between the first limiting strip 22 and the second limiting strip 23.

[0032] Specifically, when the first filter body 2 and the second filter body 3 are docked, the upper half of the filter screen inserted between the first and second limiting bars 22, 23 fits neatly between the third and fourth limiting bars 34, 35, securing the screen. A soft rubber ring bonded to the first filter body 2 is press-fitted onto the outer walls of the water inlet pipe 11 and the water delivery pipe 12, sealing the connection between the first filter body 2 and the water inlet pipe 11 and the water delivery pipe 12 and preventing leakage of the ammonium sulfate wastewater.

[0033] In order to be able to fix the first filter body 2 on the lower panel of the second filter body 3, as shown in FIG. Figures 4 to 7 As shown, a locking assembly is mounted on the second filter body 3. The locking assembly includes a pair of second docking plates 31 welded to the side walls of the second filter body 3. A bearing 311 is welded to the second docking plates 31, and a rotating rod 312 is welded to the bearing 311. The rotating rod 312 passes through the bearing 311 and the second docking plates 311. A handle 313 is welded to the upper end surface of the rotating rod 312, and a locking rod 314 is welded to the lower end surface of the rotating rod 312. A pair of first docking plates 21 are welded to the outer wall of the first filter body 2. The first docking plates 21 are provided with through slots 2101. A locking plate 211 is fixedly connected to the lower panel of the first filter body 2. The locking plate 211 is made of elastic material. The surface of the locking plate 211 away from the first docking plate 21 is inclined and gradually tilts toward the outside of the first docking plate 21.

[0034] Specifically, the rotating outer ring of the bearing 311 is welded to the second docking plate 31 , and the rotating rod 312 is welded to the rotating inner ring of the bearing 311 , so that the rotating rod 312 can rotate smoothly in the bearing 311 without changing the up and down position.

[0035] When the first filter body 2 and the second filter body 3 are docked, the locking rod 314 can pass through the through slot 2101. After the upper end surface of the first filter body 2 contacts the lower end surface of the second filter body 3, the locking rod 314 rotates clockwise by turning the handle 313. As the locking rod 314 rotates, the pressure on the locking plate 211 gradually increases. When the locking rod 314 is rotated to a position perpendicular to the long side of the locking plate 211, the pressure on the locking plate 211 is maximum, thereby locking the first filter body 2 to the second filter body 3. At this time, the locking rod 314 may deform due to the downward force. Preferably, the locking rod 314 is made of spring steel, which is resistant to bending and will not lose its elasticity due to long-term stress. The rebound force generated by the locking rod 314 can also clamp the locking plate 211.

[0036] It is worth noting that when installing the first filter body 2, the locking rod 314 must pass through the through slot 2101 to dock the first filter body 2 with the second filter body 3. A stopper 32 is fixedly attached to the outer wall of the second filter body 3. The stopper 32 is made of a magnetic material and can attract the locking rod 314. When the locking rod 314 is attracted to the stopper 32, it mates with the through slot 2101 and can pass smoothly through the through slot 2101.

[0037] Furthermore, a snap-fit ​​seat 321 is fixedly connected to one side wall of the block 32. When the first filter body 2 is locked, the tail of the handle 313 will be snapped into the snap-fit ​​seat 321. The snap-fit ​​seat 321 wraps the tail of the handle 313, making the handle 313 more stable and preventing the handle 313 from rotating and deviating after being vibrated.

[0038] The first filter body 2 is provided with a slot 201, and the second filter body 3 is fixedly connected to a plug-in plate 33 that matches the slot 201. Soft sealing strips are bonded to the side walls of the plug-in plate 33. Specifically, when docking the first filter body 2, the plug-in plate 33 is inserted into the slot 201. The soft sealing strip on the plug-in plate 33 is inserted into the slot 201 and squeezed against the slot walls of the slot 201, achieving a better sealing effect. At the same time, the friction between the soft sealing strip on the plug-in plate 33 and the slot walls of the slot 201 can temporarily secure the first filter body 2. This eliminates the need to continuously lift the first filter body 2 upward, allowing one person to dock the first filter body 2 onto the second filter body 3 during docking. Since only the first filter body 2 needs to be removed for disassembly and installation, its weight is only half the total weight of the filter device, making disassembly and installation more labor-saving.

[0039] Furthermore, flanges are provided at both ends of the insert plate 33. When the insert plate 33 is inserted into the slot 201, the left and right side walls of the first filter body 2 can be limited, so that the left and right side walls of the first filter body 2 are flush with the left and right side walls of the second filter body 3, thereby preventing the first filter body 2 from being dislocated after being impacted by the ammonium sulfate wastewater in the water pipe 12.

[0040] like Figure 8 As shown, when the first filter body 2 is docked on the second filter body 3, a placement space is naturally formed between the filter screen inserted in the first limit bar 22 and the wall of the water pipe 12. The dirt in the ammonium sulfate wastewater will be stored in the placement space. When the first filter body 2 is removed and the filter screen is replaced, the dirt in the placement space can be poured out at the same time.

[0041] During use, the handle 313 is rotated so that the handle 313 is adsorbed on the side wall of the stopper 32, and the first filter body 2 is pulled downward to separate the first filter body 2 from the second filter body 3. The filter screen inserted between the first limiting bar 22 and the second limiting bar 23 is removed and replaced, and the dirt in the first filter body 2 is poured out. When installing the first filter body 2, the slot 201 is aligned with the insert plate 33, and the first filter body 2 is pulled upward. The insert plate 33 is inserted into the slot 201. The friction between the insert plate 33 and the slot 201 temporarily fixes the first filter body 2 to the lower panel of the second filter body 3. Then, the handle 313 is rotated 90 degrees, and the locking rod 314 is pressed against the locking plate 211 to lock and fix the first filter body 2.

[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0043] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
