Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a latex paint processing wastewater treatment device. Background Technology

[0002] Latex paint is widely used in the construction industry as an environmentally friendly coating, resulting in high market demand and promoting the development of the latex paint industry. However, environmental issues must be considered alongside this development; therefore, wastewater treatment methods for latex paint production have become a focus of attention. Latex paint wastewater is mainly generated during the washing of paint mixing tanks, paint buckets, pipes, and floors, resulting in large discharge volumes, high turbidity, and high COD concentrations.

[0003] Existing technologies require the addition of activated carbon and other physicochemical materials to the wastewater after sedimentation during latex paint wastewater treatment to adsorb impurities and waste within the latex paint. However, these materials tend to disperse within the latex paint, necessitating frequent retrieval during recovery, thus increasing the difficulty and efficiency of the recovery process. Furthermore, sludge and residue remain in the wastewater during treatment, making separation and removal difficult. Additionally, the addition of various chemicals and flocculants during wastewater treatment is prone to errors and confusion among operators, and accurately determining the dosage is challenging. Therefore, we propose a latex paint processing wastewater treatment device to address these issues. Utility Model Content

[0014] Preferably, the controller is electrically connected to the motor, cylinder, first valve, and second valve.

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] (1) The three liquid tanks can be used to classify and place liquids such as polyaluminum chloride solution and polyacrylamide coagulant, making it more convenient to add liquids and avoid the confusion and wrong addition of liquids. This makes it more convenient to add flocculant to the flocculation tank. When it is necessary to add liquid to the flocculation tank, the first valve can be opened by the controller to add the liquid from the corresponding liquid tank into the flocculation tank. The amount of liquid added can be known through the scale window and the corresponding scale line on the surface of the liquid tank.

[0017] (2) The sludge can be filtered out into the separation box through the filter screen. Then, the piston rod can be extended by the cylinder, so that the piston rod can simultaneously drive the extrusion plate to move inside the separation box. The extrusion plate can squeeze the sludge filtered out inside the separation box to the right into the collection hood. At the same time, the wastewater remaining inside the sludge is squeezed out, and the sludge can also be squeezed and collected. This can achieve the separation of water and sludge, which is convenient to operate. When it is necessary to remove the sludge, the sealing cover is rotated off from the sludge inlet, and then the collection hood and the inside of the sludge inlet are removed. The sludge inside the collection hood and the sludge remaining inside the separation box can be cleaned.

[0018] (3) Activated carbon and other physical and chemical materials can be placed inside the placement frame by opening the sealing plate. Then, the placement frame can be stably installed inside the filter box by embedding the frame seat on the placement frame with the flange inside the installation groove. The partitions on both sides of the placement frame allow the activated carbon and other physical and chemical materials placed inside to fully contact the water inside the filter box. Thus, the placement frame can prevent the activated carbon and other physical and chemical materials from being dispersed inside the filter box. When it is necessary to replace the activated carbon and other physical and chemical materials, the frame seat can be pulled up to pull the placement frame out of the filter box. Then, the bottom sealing plate can be opened to replace and recycle the activated carbon and other physical and chemical materials. This solves the problem that the existing activated carbon and other physical and chemical materials are dispersed inside the filter box and are difficult to recycle and replace.

[0036] In this embodiment, three liquid medicine tanks 102 are provided, and the three liquid medicine tanks 102 are distributed at equal intervals on the top of the flocculation tank 1.

[0037] In practical use, the three liquid tanks 102 can be used to classify and place liquids such as polyaluminum chloride solution and polyacrylamide coagulant, making it more convenient to add liquids and avoiding confusion and incorrect addition. This also makes it more convenient to add flocculant to the flocculation tank 1. When it is necessary to add liquid to the flocculation tank 1, the controller 5 controls the first valve 104 to open, which allows the liquid from the corresponding liquid tank 102 to be added into the flocculation tank 1. The amount of liquid added can be determined by the scale window 105 and the corresponding scale lines on the surface of the liquid tank 102.

[0038] In this embodiment, the stirring blades 108 are arranged in an alternating structure.

[0039] In practical use, the motor can drive the shaft 107 to rotate, and the shaft 107 can synchronously drive the stirring blade 108 to rotate, so that the stirring blade 108 can stir the wastewater and flocculant, so that the wastewater and flocculant can react fully and form clumps of vanadium flocs in the water.

[0040] In this embodiment, the extrusion plate 203 is adapted to the interior of the separation box 2, and the storage cover 205 and the inside of the sewage outlet 204 are embedded.

[0041] In practical use, the sludge can be filtered out into the separation box 2 through the filter screen 207. Then, the piston rod 202 can be extended by the cylinder 201, so that the piston rod 202 can simultaneously drive the extrusion plate 203 to move inside the separation box 2. The extrusion plate 203 can squeeze the sludge filtered out inside the separation box 2 to the right into the collection cover 205. At the same time, the wastewater remaining inside the sludge is squeezed out, and the sludge is also squeezed and collected, thus achieving the separation of water and sludge. The operation is convenient. When it is necessary to remove the sludge, the sealing cover 206 is rotated off from the sewage outlet 204, and then the collection cover 205 and the inside of the sewage outlet 204 are removed, so that the sludge inside the collection cover 205 and the sludge remaining inside the separation box 2 can be cleaned.

[0042] In this embodiment, the two placement frames 303 are arranged symmetrically, and the frame base 302 and the mounting groove 301 have a flange inlay structure.

[0043] In practical use, activated carbon and other physical and chemical materials can be placed inside the placement frame 303 by opening the sealing plate 306. Then, the placement frame 303 is stably installed inside the filter box 3 by the frame seat 302 on the placement frame 303 and the flange inside the mounting groove 301. The partition nets 304 on both sides of the placement frame 303 ensure that the activated carbon and other physical and chemical materials placed inside can fully contact the water inside the filter box 3. Thus, the placement frame 303 can prevent the activated carbon and other physical and chemical materials from being dispersed inside the filter box 3. When it is necessary to replace the activated carbon and other physical and chemical materials, the frame seat 302 can be pulled upward to pull the placement frame 303 out of the filter box 3. Then, the bottom sealing plate 306 can be opened to replace and recycle the activated carbon and other physical and chemical materials. This solves the problem that the existing activated carbon and other physical and chemical materials are dispersed inside the filter box 3 and are difficult to recycle and replace.

[0044] In this embodiment, the limiting plates 309 are arranged in pairs with a symmetrical structure.

[0045] In practical use, the pivot 308 can drive the limiting plate 309 to rotate and move. When the placement frame 303 is installed inside the filter box 3, the limiting plate 309 can be rotated to fit tightly against the surface of the frame seat 302, thereby limiting the frame seat 302 and preventing the placement frame 303 from moving.

[0046] In this embodiment, the controller 5 is electrically connected to the motor 106, cylinder 201, first valve 104, and second valve 110.

[0047] In practical use, the controller 5 can control the working status of the motor 106, cylinder 201, first valve 104, and second valve 110.

[0048] The working principle of the latex paint processing wastewater treatment device mentioned in this utility model is as follows:

[0049] When in use, latex paint wastewater can be discharged into the flocculation box 1 by connecting the liquid inlet 101 to the external pipe via a threaded connection.

[0050] Then, the three liquid tanks 102 can be used to classify and place the polyaluminum chloride solution, polyacrylamide coagulant, and other liquids, making it more convenient to add liquids and avoiding confusion and incorrect addition. This makes it more convenient to add flocculant to the flocculation tank 1. When it is necessary to add liquid to the flocculation tank 1, the controller 5 controls the first valve 104 to open, which will add the liquid from the corresponding liquid tank 102 into the flocculation tank 1. The amount of liquid added can be determined by the scale window 105 and the corresponding scale lines on the surface of the liquid tank 102.

[0051] Then, the motor drives the shaft 107 to rotate, and the shaft 107 can synchronously drive the stirring blade 108 to rotate, so that the stirring blade 108 can stir the wastewater and flocculant, so that the wastewater and flocculant can react fully and form clumps of flocculants in the water. Then, by opening the second valve 110, the wastewater inside the flocculation box 1 can flow into the separation box 2 through the connecting pipe 109.

[0052] Then, the sludge can be filtered out into the separation box 2 through the filter screen 207, and the wastewater can flow downward into the filter box 3. Then, the piston rod 202 can be extended by the cylinder 201, so that the piston rod 202 can simultaneously drive the extrusion plate 203 to move inside the separation box 2. The extrusion plate 203 can squeeze the sludge filtered out inside the separation box 2 to the right into the collection cover 205. Thus, while squeezing out the wastewater remaining inside the sludge, the sludge can also be squeezed and collected, thereby achieving the separation of water and sludge. The operation is convenient. When it is necessary to remove the sludge, the sealing cover 206 is rotated off from the sewage outlet 204, and then the collection cover 205 and the inside of the sewage outlet 204 are removed, so that the sludge inside the collection cover 205 and the sludge remaining inside the separation box 2 can be cleaned.

[0053] Then, by opening the sealing plate 306, activated carbon and other physical and chemical materials can be placed inside the placement frame 303. The frame seat 302 on the placement frame 303 is then embedded with the flange inside the mounting groove 301, allowing the placement frame 303 to be stably installed inside the filter box 3. The partitions 304 on both sides of the placement frame 303 ensure that the activated carbon and other physical and chemical materials placed inside can fully contact the water inside the filter box 3. Thus, the placement frame 303 can prevent the activated carbon and other physical and chemical materials from being dispersed inside the filter box 3. When it is necessary to replace the activated carbon and other physical and chemical materials, the frame seat 302 can be pulled upward to pull the placement frame 303 out of the filter box 3. Then, by opening the sealing plate 306 at the bottom, the activated carbon and other physical and chemical materials can be replaced and recycled. This solves the problem that the existing activated carbon and other physical and chemical materials are dispersed inside the filter box 3 and are difficult to recycle and replace.

[0054] Then, the latex paint wastewater can be treated by physical and chemical materials such as activated carbon placed inside the filter plate 310 and placement frame 303 inside the filter box.

[0055] Then, by connecting the outlet 311 to an external pipe via a threaded connection, the filtered water can be discharged to the outside.

[0056] Meanwhile, the pivot 308 can drive the limiting plate 309 to rotate and move. When the placement frame 303 is installed inside the filter box 3, the limiting plate 309 can be rotated to fit tightly against the surface of the frame seat 302, thereby limiting the frame seat 302 and preventing the placement frame 303 from moving.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
