[0002] Wastewater treatment is an important part of titanium dioxide production. Traditional wastewater treatment methods usually involve the use of fixed filtration equipment for solid-liquid separation to remove impurities and particulate matter from wastewater. However, these traditional equipment have some significant problems and limitations during use.

[0003] First, the filter screen of traditional filtration equipment is often fixed, which leads to the filter screen being easily clogged after long-term use, and the filtration efficiency is greatly reduced. The clogged filter screen not only affects the wastewater treatment speed, but also may cause equipment failure and increase maintenance costs.

[0004] Secondly, the filter replacement and cleaning process of traditional equipment is usually cumbersome. Since the filter is fixed, operators need to spend a lot of time and energy to disassemble and assemble it when replacing or cleaning the filter, which not only reduces work efficiency, but may also damage the filter or equipment due to improper operation. In view of this, we propose a titanium dioxide production wastewater recovery equipment. Utility Model Content

[0025] A titanium dioxide production wastewater recovery device includes a filter box 1, wherein a plurality of filter components are arranged inside the filter box 1, wherein the filter components include an outer frame 2 which is symmetrically arranged and can be pulled out of the filter box 1, a filter screen 21 is installed at the bottom of the outer frame 2, and a limit bar 23 is integrally formed on the outer walls of the two opposite sides of the outer frame 2, and the filter box 1 is provided with a first slide 13 which is slidably connected to the limit bar 23, and a transmission shaft 70 which can move up and down is arranged inside the filter box 1, and a first installation shaft 71 is fixedly connected to the circumferential outer wall of the transmission shaft 70 located above each filter component, and at least one scraper 72 is fixedly connected to the circumferential outer wall of the first installation shaft 71, and the top of the first installation shaft 71 extends from the top of the filter box 1, and an adjustment motor 7 for driving the first installation shaft 71 to rotate is installed above the filter box 1. By providing a filter box 1 with a removable filter component, the filter screen 21 can be easily replaced or cleaned, thereby improving the use efficiency and convenience of the equipment. The arrangement of the transmission shaft 70 and the scraper 72 can clean the residue on the filter screen 21 in real time, prevent clogging, maintain the filtering efficiency, and also reduce the cost of manual maintenance. It should be added that the filter box 1 is provided with a placement opening 12 for extracting the filter assembly.

[0026] As a preferred embodiment of the present invention, a water inlet pipe 10 is installed at the top of the filter box 1, and a water outlet pipe 11 is installed at the discharge port 15 at the bottom. By installing the water inlet pipe 10 at the top of the filter box 1 and the water outlet pipe 11 at the bottom, continuous treatment and discharge of wastewater is achieved, thereby improving the efficiency of wastewater treatment.

[0027] As a preferred embodiment of the present invention, a conical groove 14 is provided at the bottom of the filter box 1, and the bottom of the conical groove 14 points to the top of the discharge port 15. The conical groove 14 is provided to facilitate the discharge of wastewater.

[0028] As a preferred embodiment of the present invention, the filter screen 21 of each filter assembly is provided with a through hole 22 for the transmission shaft 70 to pass through. The through hole 22 provided on the filter screen 21 of each filter assembly allows the transmission shaft 70 to pass through. This design allows the transmission shaft 70 to move up and down without affecting the filtering function of the filter screen 21. When the filter assembly is taken out, the scraper 72 can be moved upward to be separated from the filter assembly, so that it will not affect the removal of the filter residue.

[0029] As a preferred embodiment of the present invention, a fixing plate 3 is fixedly connected to the outer wall of each outer frame 2, and the fixing plate 3 is fixedly connected to the outer wall of the filter box 1 by fixing bolts 31, and a handle 30 is fixedly installed on the outer wall of the fixing plate 3. The outer frame 2 is fixed to the filter box 1 by the fixing plate 3 and the fixing bolts 31, which enhances the stability and safety of the device. At the same time, the handle 30 installed on the fixing plate 3 can easily pull out the outer frame 2 to replace or clean the filter screen 21, thereby improving the convenience of using the device.

[0030] As a preferred embodiment of the present invention, an L-shaped support plate 5 is fixedly connected to the top of the filter box 1, and a hydraulic cylinder 6 for driving the adjustment motor 7 to move up and down is fixedly installed on the L-shaped support plate 5. The hydraulic cylinder 6 installed on the L-shaped support plate 5 can drive the adjustment motor 7 to move up and down, thereby driving the transmission shaft 70 and the scraper 72 to move up and down.

[0031] As a preferred embodiment of the present invention, a second mounting shaft 73 is rotatably mounted on the bottom end of the transmission shaft 70 through a bearing 730, four fixing rods 74 are fixed to the circumferential outer wall of the second mounting shaft 73, and a limiting block 740 is integrally formed at the end of the fixing rod 74, and a second slide groove 16 connected to the limiting block 740 for upward and downward sliding movement is provided on the inner wall of the filter box 1. The second mounting shaft 73 and the fixing rod 74 can provide stable support and guidance when the transmission shaft 70 moves up and down, prevent the transmission shaft 70 from deflecting or shaking, and improve the stability and durability of the equipment.

[0032] As a preferred embodiment of the present invention, at least three legs 4 for supporting the filter box 1 are fixedly installed at the bottom thereof. The legs 4 fixedly installed at the bottom of the filter box 1 can provide stable support for the device.

[0033] When the titanium dioxide production wastewater recovery device of the utility model is used, first, the wastewater flows into the filter box 1 through the water inlet pipe 10 at the top of the filter box 1. When the wastewater flows through each filter component, the filter screen 21 intercepts solid particles and impurities in the wastewater, thereby achieving preliminary filtration of the wastewater.

[0034] During filtration, the hydraulic cylinder 6 is activated to fit the scraper 72 to the top of the filter screen 21. Subsequently, the regulating motor 7 is activated to drive the first mounting shaft 71 and the scraper 72 to rotate. The scraper 72 scrapes off the filter residue on the filter screen 21 during rotation, maintains the permeability of the filter screen 21, and ensures the filtration efficiency.

[0035] When the filter screen 21 of a certain filter assembly needs to be replaced or cleaned, the operator can conveniently pull out the outer frame 2 through the handle 30 and the fixing bolt 31 .

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
