Description

Technical Field

[0001] This utility model relates to the field of industrial wastewater treatment technology, and in particular to a material recovery device for titanium dioxide waste acid wastewater. Background Technology

[0002] Titanium dioxide, an inorganic white dye, is non-toxic and chemically stable, and is widely used in coatings, papermaking, and plastics manufacturing. However, the current production process of titanium dioxide in my country mainly uses the sulfuric acid process. The first, second, and third washing processes in the production process generate a large amount of wastewater containing a large number of titanium dioxide particles. If this wastewater is not treated and recycled, it will not only result in the loss of titanium dioxide but also cause environmental pollution.

[0003] In existing technologies for recycling wastewater from titanium dioxide production, the wastewater needs to be filtered through a filter screen. However, after prolonged use, the filter screen is prone to clogging, which prevents it from filtering the wastewater properly and renders the recycling device unusable. Utility Model Content

[0004] This utility model proposes a material recovery device for titanium dioxide waste acid wastewater to overcome the shortcomings of existing technologies.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a material recovery device for titanium dioxide waste acid wastewater, comprising a shell, the shell being placed on the ground to provide support for the whole, an inlet pipe being fixedly connected to one side of the shell, an outlet pipe being fixedly connected to the bottom of the shell, a filter screen being fixedly connected inside the shell, wherein the filter screen is inclined, a striking device being disposed inside the shell, wherein the striking device can continuously strike the filter screen, and a collection device being disposed on one side of the shell, wherein the collection device is located at the lower part of the inclined filter screen.

[0006] The effect achieved by the above components is as follows: when recycling titanium dioxide wastewater, the staff sends the titanium dioxide wastewater into the interior of the shell through the inlet pipe, the filter screen filters the titanium dioxide wastewater, and the knocking device continuously knocks on the filter screen to prevent the filter screen from clogging. The cleaned impurities are collected by the collection device, and the filtered clean water is discharged through the outlet pipe.

[0007] Preferably, the striking device includes a rotating shaft rotatably connected to the inner wall of the housing. A plurality of fan blades are fixedly connected to the arc surface of the rotating shaft. An eccentric circle is fixedly connected to the arc surface of the rotating shaft. A bracket is fixedly connected to the corresponding eccentric circle of the filter screen. A support rod slides through the surface of the support rod, wherein the support rod is located directly below the eccentric circle. A striking block is fixedly connected to one end of the support rod. A spring is sleeved on the arc surface of the support rod, and both ends of the spring are fixedly connected to the striking block and the bracket, respectively.

[0008] The effect achieved by the above components is as follows: when wastewater is sent into the interior of the casing through the inlet pipe, the wastewater drives the fan blades of the rotating shaft to rotate, and the rotating shaft rotates the eccentric circle. When the protruding end of the eccentric circle moves to the position of the support rod, the support rod, along with the striking block, strikes the filter screen, causing the spring to deform. When the protruding end of the eccentric circle moves away from the support rod, under the action of the spring's restoring force, the support rod, along with the striking block, moves away from the filter screen. As the eccentric circle continues to rotate, the striking block will continuously strike the filter screen, preventing the filter screen from becoming clogged. The striking device achieves the effect of cleaning the filter screen, preventing the filter screen from being clogged by impurities, thus preventing the wastewater from failing to be filtered.

[0009] Preferably, a rubber pad is fixedly connected to one side of the striking block, wherein the size of the rubber pad is adapted to the size of the striking block.

[0010] The effect achieved by the above components is that the rubber pads protect the filter screen and prevent the impact blocks from damaging it.

[0011] Preferably, one end of the support rod is fixedly connected to a U-shaped plate, and the two arms of the U-shaped plate are rotatably connected to the same rotating component.

[0012] The effect achieved by the above components is as follows: by setting the rotating part to rotate with the arc surface of the eccentric circle, the friction between the support rod and the eccentric circle is reduced, making it easier for the eccentric circle to rotate with the support rod.

[0013] Preferably, the arc surface of the support rod is fixedly connected to a limiting member, wherein the limiting member slides through the bracket.

[0014] The effect achieved by the above components is that by setting the limiting component, the direction of movement of the support rod is restricted, thus preventing the support from rotating.

[0015] Preferably, the collecting device includes a collecting frame that slides through the outer shell, wherein the collecting frame can abut against one side of the filter screen, a fixing plate is fixedly connected to one side of the collecting frame, two mounting plates are respectively fixedly connected to both sides of the fixing plate, bolts are threaded through the surface of the mounting plate, and threaded holes are provided on the outer shell corresponding to the bolts, wherein the size of the bolts is adapted to the size of the threaded holes.

[0016] The aforementioned components achieve the following effects: Before wastewater filtration, the operator moves the fixing plate, which, along with the collection frame, inserts into the housing. The collection frame rests against one side of the filter screen. Then, the operator moves the bolts, which pass through the mounting plate and insert into the threaded holes in the housing, thus securing the collection frame. When the filter screen filters the wastewater, the impurities filtered out fall into the collection frame, achieving the effect of collecting the impurities. This collection device effectively collects the impurities removed by the filter screen, facilitating unified processing of the impurities and providing convenience for the operator.

[0017] Preferably, a handle is fixedly connected to one side of the fixing plate, and the surface of the handle is provided with anti-slip texture.

[0018] The effect achieved by the above-mentioned components is to increase the contact area between the worker's hand and the fixed plate by setting handles, thereby making it easier for the worker to move the fixed plate.

[0019] Preferably, a sealing ring, which is a rubber ring, is fixedly connected to the side of the fixing plate near the outer shell.

[0020] The effect achieved by the above components is that by setting a sealing ring, the gap between the fixing plate and the outer shell is sealed, preventing wastewater from flowing out from the gap.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] When wastewater is fed into the casing through the inlet pipe, it drives the fan blades of the rotating shaft to rotate. The rotating shaft rotates the eccentric circle. When the protruding end of the eccentric circle moves to the position of the support rod, the support rod, along with the striking block, strikes the filter screen. The spring deforms. When the protruding end of the eccentric circle moves away from the support rod, the spring's restoring force causes the support rod to move the striking block away from the filter screen. As the eccentric circle continues to rotate, the striking block continuously strikes the filter screen, preventing it from becoming clogged. This striking device effectively cleans the filter screen, preventing it from being blocked by impurities and thus ensuring that the wastewater cannot be filtered. Attached Figure Description

[0029] Reference Figure 1-5 As shown, this embodiment discloses a material recovery device for titanium dioxide waste acid wastewater, including a shell 1, which is placed on the ground to provide support for the whole. A water inlet pipe 2 is fixedly connected to one side of the shell 1, and a water outlet pipe 3 is fixedly connected to the bottom of the shell 1; a filter screen 4, which is fixedly connected inside the shell 1 and is inclined; a striking device 5, which is located inside the shell 1 and continuously strikes the filter screen 4; and a collecting device 6, which is located on one side of the shell 1 at the lower part of the inclined filter screen 4. During the recovery of titanium dioxide wastewater, workers send the wastewater into the shell 1 through the water inlet pipe 2. The filter screen 4 filters the wastewater, while the striking device 5 continuously strikes the filter screen 4 to prevent clogging. The impurities removed are collected by the collecting device 6, and the filtered water is discharged through the water outlet pipe 3.

[0030] Reference Figure 1-5As shown, the striking device 5 includes a rotating shaft 51, which is rotatably connected to the inner wall of the outer casing 1. Several fan blades 52 are fixedly connected to the arc surface of the rotating shaft 51. An eccentric circle 53 is fixedly connected to the arc surface of the rotating shaft 51. A bracket 54 is fixedly connected to the corresponding eccentric circle 53 of the filter screen 4. A support rod 55 slides through the surface of the support rod 54. The support rod 55 is located directly below the eccentric circle 53. A striking block 56 is fixedly connected to one end of the support rod 55. A spring 57 is sleeved on the arc surface of the support rod 55. The two ends of the spring 57 are fixedly connected to the striking block 56 and the bracket 54, respectively. When wastewater is sent into the interior of the outer casing 1 through the inlet pipe 2, the wastewater drives the fan blades 52 of the rotating shaft 51 to rotate. The rotating shaft 51 rotates the eccentric circle 53. When the protruding end of the eccentric circle 53 moves to the position of the support rod 55, the support rod 55, along with the striking block 56, strikes the filter screen 4. The spring 57 deforms. When the protruding end of the eccentric circle 53 moves away from the support rod 55, under the action of the spring 57's restoring force, the support rod 55, along with the striking block 56, moves away from the filter screen 4. As the eccentric circle 53 continues to rotate, the striking block 56 will continuously strike the filter screen 4 to prevent the filter screen 4 from becoming clogged. The striking device 5 achieves the cleaning effect of the filter screen 4, preventing the filter screen 4 from being clogged by impurities, thus preventing the wastewater from being unable to be filtered.

[0031] Reference Figure 1-5 As shown, a rubber pad 59 is fixedly connected to one side of the striking block 56, and the size of the rubber pad 59 is adapted to the size of the striking block 56. The rubber pad 59 protects the filter screen 4, preventing the striking block 56 from damaging it. A U-shaped plate 510 is fixedly connected to one end of the support rod 55, and the two arms of the U-shaped plate 510 are rotatably connected to the same rotating component 511. By setting the rotating component 511 to rotate with the arc surface of the eccentric circle 53, the friction between the support rod 55 and the eccentric circle 53 is reduced, facilitating the rotation of the support rod 55 by the eccentric circle 53. A limiting component 58 is fixedly connected to the arc surface of the support rod 55, and the limiting component 58 slides through the bracket 54. The limiting component 58 restricts the direction of movement of the support rod 55, preventing the bracket 54 from rotating.

[0032] Reference Figure 1-5As shown, the collection device 6 includes a collection frame 61, which slides through the outer shell 1. The collection frame 61 can abut against one side of the filter screen 4. A fixing plate 62 is fixedly connected to one side of the collection frame 61. Two mounting plates 63 are fixedly connected to both sides of the fixing plate 62. Bolts 64 are threaded through the surface of the mounting plates 63. The outer shell 1 has threaded holes corresponding to the bolts 64. The size of the bolts 64 is adapted to the size of the threaded holes. Before the wastewater needs to be filtered, the staff moves the fixing plate 62, which inserts the collection frame 61 into the interior of the outer casing 1. The collection frame 61 rests against one side of the filter screen 4. Then, the staff moves the bolt 64, which passes through the mounting plate 63 and is inserted into the threaded hole of the outer casing 1, thus fixing the collection frame 61. When the filter screen 4 filters the wastewater, the impurities filtered out by the filter screen 4 fall into the collection frame 61, thus collecting the impurities. The collection device 6 collects the impurities cleaned out by the filter screen 4, making it convenient for the staff to handle the impurities in a unified manner, bringing convenience to the staff.

[0033] Reference Figure 1-5 As shown, a handle 66 is fixedly connected to one side of the fixed plate 62, and the surface of the handle 66 is provided with anti-slip texture. By setting the handle 66, the contact area between the worker's hand and the fixed plate 62 is increased, thereby facilitating the worker's movement of the fixed plate 62. A sealing ring 65, which is a rubber ring, is fixedly connected to the side of the fixed plate 62 near the outer shell 1. By setting the sealing ring 65, the gap between the fixed plate 62 and the outer shell 1 is sealed, preventing wastewater from flowing out from the gap.

[0034] Working principle: When recycling titanium dioxide wastewater, the worker sends the wastewater into the interior of the outer casing 1 through the inlet pipe 2. The wastewater drives the fan blades 52 of the rotating shaft 51 to rotate, and the rotating shaft 51 drives the eccentric circle 53 to rotate. When the protruding end of the eccentric circle 53 moves to the position of the support rod 55, the eccentric circle 53 drives the support rod 55 to move through the rotating part 511 on the U-shaped plate 510. The support rod 55, with the striking block 56, strikes the filter screen 4 with the help of the rubber pad 59. The spring 57 deforms, and when the eccentric circle 53 moves to the position of the support rod 55, the eccentric circle 53 moves to the position of the support rod 55. When the protruding end moves away from the support rod 55, under the action of the spring 57's return force, the support rod 55 carries the striking block 56 away from the filter screen 4. As the eccentric circle 53 rotates continuously, the striking block 56 will continuously strike the filter screen 4 to prevent the filter screen 4 from becoming clogged. The filter screen 4 filters the titanium dioxide wastewater, and the filtered clean water is discharged through the outlet pipe 3. The striking device 5 achieves the cleaning effect of the filter screen 4, preventing the filter screen 4 from being clogged by impurities, which would prevent the wastewater from being filtered.

[0035] Before the wastewater needs to be filtered, the operator moves the fixing plate 62 using handle 66. The fixing plate 62, along with the collection frame 61, is inserted into the interior of the outer casing 1. The collection frame 61 rests against one side of the filter screen 4. Then, the operator moves the bolt 64, which passes through the mounting plate 63 and is inserted into the threaded hole of the outer casing 1, thus fixing the collection frame 61 in place. When the filter screen 4 filters the wastewater, the impurities filtered out by the filter screen 4 fall into the collection frame 61, achieving the effect of collecting the impurities. The collection device 6 effectively collects the impurities removed by the filter screen 4, facilitating the unified treatment of impurities by the operator and providing convenience.
