[0002] Concentrated sulfuric acid waste acid treatment refers to the process of effectively separating soluble substances present in dilute acid solutions and recycling them after purification. Various methods exist for waste acid treatment, including but not limited to neutralization, evaporation and concentration, biological treatment, ion exchange, washing and dilution, crystallization, and precipitation. The choice of these methods depends on the characteristics and concentration of the waste acid, as well as whether specific environmental standards need to be met after treatment.

[0003] In the treatment of concentrated sulfur waste acid, filters are usually used to filter the concentrated sulfur waste acid. When traditional filters filter concentrated sulfur waste acid, impurities may accumulate, causing the filter plates to become clogged and affecting the normal use of the equipment.

[0004] In the process of realizing this utility model, the inventors discovered the following problems with the prior art: 1. The filter plates of existing filters are usually installed inside the filter, making it difficult to quickly remove the filter plates and inconvenient to maintain and replace them; 2. When existing filters filter concentrated sulfur waste acid, impurities accumulate, causing the filter plates to become clogged, and it is inconvenient to effectively clean the filter plates, affecting the normal use of the equipment. Utility Model Content

[0005] The purpose of this utility model is to provide a concentrated sulfuric acid waste filter with a self-cleaning function to solve the problems of inconvenient maintenance and inconvenient cleaning of filter plates mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: a concentrated sulfuric acid waste filter with a self-cleaning function, including a tank body, with support blocks installed at the four corners of the bottom of the tank body, one end of a first hydraulic push rod installed at the bottom of the support block, and a support platform installed at the other end of the first hydraulic push rod, with a discharge port installed in the middle of the bottom of the tank body, a filter plate installed on the inner wall of the tank body, a main connecting block installed on one side surface of the filter plate, a secondary connecting block installed on the top surface of the main connecting block, a threaded rod installed on the inner wall of the secondary connecting block, and a handle installed on the top surface of the threaded rod, with a feed inlet installed on one side of the outer wall of the tank body, and a tank cover installed at the top of the tank body, with a cleaning component installed on the top surface of the tank cover.

[0006] The cleaning assembly includes a motor mounted on the top surface of the can lid, a second hydraulic push rod mounted on the output end of the motor, a brush cylinder mounted on the outer wall of the second hydraulic push rod, one end of a third hydraulic push rod mounted on the inner wall of the brush cylinder, and a cleaning brush mounted on the other end of the third hydraulic push rod.

[0019] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 3 This utility model provides a technical solution: a concentrated sulfur waste acid filter with self-cleaning function, including a tank body 1, support blocks 2 installed at the four corners of the bottom of the tank body 1, one end of a first hydraulic push rod 3 installed at the bottom of the support block 2, and a support platform 4 installed at the other end of the first hydraulic push rod 3, a discharge port 5 installed in the middle of the bottom of the tank body 1, a filter plate 6 installed on the inner wall of the tank body 1, a main connecting block 7 installed on one side surface of the filter plate 6, a secondary connecting block 8 installed on the top surface of the main connecting block 7, a threaded rod 9 installed on the inner wall of the secondary connecting block 8, a handle 10 installed on the top surface of the threaded rod 9, a feed inlet 11 installed on one side of the outer wall of the tank body 1, a tank cover 12 installed on the top of the tank body 1, and a cleaning component 13 installed on the top surface of the tank cover 12.

[0021] The cleaning assembly 13 includes a motor 1301 mounted on the top surface of the can lid 12. A second hydraulic push rod 1302 is mounted on the output end of the motor 1301. A brush cylinder 1303 is mounted on the outer wall of the second hydraulic push rod 1302. One end of a third hydraulic push rod 1304 is mounted on the inner wall of the brush cylinder 1303. A cleaning brush 1305 is mounted on the other end of the third hydraulic push rod 1304.

[0022] In this embodiment, as Figure 2 As shown, sealing rings are provided at the connection between the filter plate 6 and the tank 1; this design makes the connection between the filter plate 6 and the tank 1 tighter, effectively improving the sealing performance of the equipment and preventing waste acid leakage.

[0023] In this embodiment, as Figure 2As shown, a plug is provided on one side surface of the filter plate 6, and a slot with an internal size structure that matches the external size structure of the plug is provided on the inner wall of the tank body 1. The filter plate 6 and the tank body 1 form a plug-in mechanism. With this design, the user can quickly plug the filter plate 6 into the tank body 1 through the plug and slot, and can also quickly separate the filter plate 6 from the tank body 1 through the plug and slot, which is convenient for the maintenance and replacement of the filter plate 6.

[0024] In this embodiment, as Figure 2 As shown, the top surface of the main connecting block 7 is provided with a slider, and the bottom surface of the auxiliary connecting block 8 is provided with a groove whose internal dimensions are consistent with the external dimensions of the slider. The top surface of the main connecting block 7 is provided with a mounting hole whose internal dimensions are consistent with the external dimensions of the threaded rod 9. At the same time, the handle 10 and the threaded rod 9 form a screw drive mechanism. With this design, when the filter plate 6 is inserted into the tank 1, the main connecting block 7 is slidably connected to the auxiliary connecting block 8 through the slider and the groove. At this time, the mounting hole on the surface of the main connecting block 7 is located directly below the threaded rod 9, which makes it convenient for the user to rotate the handle 10 to drive the threaded rod 9 to rotate and move downward. The threaded rod 9 fixes the main connecting block 7 and the auxiliary connecting block 8, thereby fixing the filter plate 6 to the tank 1.

[0025] In this embodiment, as Figure 3 As shown, the third hydraulic push rod 1304 and the cleaning brush 1305 constitute a telescopic mechanism. With this design, when the user needs to clean the inner wall of the tank 1 and the surface of the filter plate 6, the third hydraulic push rod 1304 can be activated to extend the cleaning brush 1305 from the brush cylinder 1303. After cleaning is completed, the third hydraulic push rod 1304 can be activated to retract the cleaning brush 1305 into the brush cylinder 1303.

[0026] In this embodiment, as Figure 3 As shown, cleaning brushes 1305 are provided on the bottom and one side surface of the brush cylinder 1303. The motor 1301 forms a transmission mechanism with the brush cylinder 1303 through the second hydraulic push rod 1302, and the second hydraulic push rod 1302 forms a lifting mechanism with the brush cylinder 1303. With this design, when the user extends the cleaning brush 1305 from the brush cylinder 1303, the second hydraulic push rod 1302 can be activated to lower the cleaning brush 1305 to contact the filter plate 6. Then, the motor 1301 is activated, and the motor 1301 drives the second hydraulic push rod 1302 to rotate, which in turn drives the brush cylinder 1303 and the cleaning brush 1305 to rotate. The cleaning brush 1305 rotates and cleans the filter plate 6, preventing impurities from clogging the filter plate 6. The second hydraulic push rod 1302 can also control the brush cylinder 1303 and the cleaning brush 1305 to rise and fall, effectively cleaning the inner wall of the tank 1 and preventing impurities from affecting the use of the equipment.

[0027] The usage and advantages of this utility model: The working process of this concentrated sulfur waste acid filter with self-cleaning function is as follows:

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, the height of the equipment is first adjusted by the first hydraulic push rod 3. Then, concentrated sulfur waste acid is conveyed into the tank 1 through the inlet 11. The concentrated sulfur waste acid is filtered through the filter plate 6, and the filtered concentrated sulfur waste acid is discharged through the outlet 5. When impurities clog the filter plate 6, the third hydraulic push rod 1304 can be activated to extend the cleaning brush 1305 from the brush cylinder 1303. Then, the second hydraulic push rod 1302 is activated to lower the cleaning brush 1305 to contact the filter plate 6. Next, the motor 1301 is activated, and the motor 1301 drives the second hydraulic push rod 1302 to rotate, which in turn drives the brush cylinder 1303 and the cleaning brush 1305 to rotate. The cleaning brush 1305 rotates and cleans the filter plate 6. The second hydraulic push rod 1302 can also control the rotation of the brush cylinder 1303 and the cleaning brush 1305. The cleaning brush 1305 rises and falls to effectively clean the inner wall of the tank 1, preventing impurities from affecting the use of the equipment. When the user needs to maintain or replace the filter plate 6, the handle 10 can be rotated to rotate the threaded rod 9, causing the threaded rod 9 to move upward and separate from the mounting hole. Then, the filter plate 6 is quickly separated from the tank 1 through the insert and slot. At the same time, the main connecting block 7 and the auxiliary connecting block 8 are quickly separated, allowing the filter plate 6 to be removed for maintenance or replacement. After replacement, the filter plate 6 is quickly inserted into the tank 1 through the insert and slot. Then, the handle 10 is rotated to rotate the threaded rod 9 downward, fixing the main connecting block 7 and the auxiliary connecting block 8 through the threaded rod 9, thereby fixing the filter plate 6 to the tank 1.
