Description

Technical Field

[0001] This utility model relates to the field of wastewater adsorption treatment technology, specifically a modified pomelo leaf residue filtration device suitable for adsorption treatment of dyeing and printing wastewater. Background Technology

[0002] Modified pomelo leaf residue filtration equipment, suitable for the adsorption treatment of dyeing and printing wastewater, is mainly used for the treatment of dyeing and printing wastewater. It removes pollutants from the wastewater by using modified pomelo leaf residue as an adsorbent. Modified pomelo leaf residue has advantages such as low cost, wide availability, and environmental friendliness. Furthermore, after appropriate modification, its adsorption performance is significantly improved, making it suitable for the treatment of dyeing and printing wastewater.

[0003] In existing equipment, an inlet pipe is typically used to introduce dyeing and printing wastewater, while a reagent pipe is used to add modified pomelo leaf residue adsorbent. The two are mixed inside the equipment to improve adsorption efficiency, and a multi-stage filter screen is used to filter solid particles in the wastewater. The filter screen is equipped with bristles that are rotated by a shaft to clean the adsorbent deposited on the filter screen and prevent clogging.

[0004] However, while the brush plate removes some impurities from the filter screen during cleaning, some are still pushed deeper into the filter pores by the bristles, causing the filter plate to clog more quickly. Therefore, those skilled in the art have provided a modified pomelo leaf residue filtration device suitable for the adsorption treatment of dyeing and printing wastewater to solve the problems mentioned in the background art. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a modified pomelo leaf residue filtration device suitable for the adsorption treatment of dyeing and printing wastewater. However, while the brush plate cleans the filter screen, some impurities are removed, but some are still pushed deep into the filter holes by the bristles on the brush plate, causing the filter plate to clog more quickly.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a modified pomelo leaf residue filtration device suitable for adsorption treatment of dyeing and printing wastewater, comprising a shell, a limiting ring installed on the inner wall of the shell, a first filter disc arranged inside the shell, a second filter disc arranged below the first filter disc, a third filter disc arranged below the second filter disc, a limiting ring formed on the outer wall of the first filter disc, turbulence-inducing blades installed on the upper sidewalls of the first, second, and third filter discs, annular grooves formed on the outer walls of the first, second, and third filter discs, a motor installed on the top of the shell, a rotating shaft driven by the lower output end of the motor, a wastewater input pipe connected to the top side of the shell, a reagent input pipe connected to one side of the shell, a reagent output pipe connected to the side of the shell away from the reagent input pipe, and a drain pipe connected to the bottom of the shell.

[0009] Preferably, a fixing seat is installed at the bottom of the housing, and the housing is inclined.

[0010] Preferably, the first filter disc is rotatably engaged with the limiting ring via an annular groove, and the rotating shaft is sequentially fixed through the first filter disc, the second filter disc, and the third filter disc. The motor drives the rotating shaft to rotate, and the rotation of the rotating shaft causes the first filter disc, the second filter disc, and the third filter disc to rotate. When the first filter disc, the second filter disc, and the third filter disc rotate, the turbulence blades rotate accordingly. When mixing the waste liquid and the adsorbent liquid, the turbulence blades can push the mixed liquid upward, preventing the adsorbed impurity particles from remaining on the first filter disc, the second filter disc, or the third filter disc.

[0011] Preferably, a positioning sleeve is installed on the bottom inner wall of the housing, and the positioning sleeve is rotatably inserted into the rotating shaft for positioning the rotating shaft.

[0012] Preferably, the agent output pipe is equipped with a solenoid valve, which can be opened during equipment cleaning to discharge the modified pomelo leaf residue adsorbed in the chambers of the first, second, and third filter discs.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a modified pomelo leaf residue filtration device suitable for adsorption treatment of dyeing and printing wastewater, which has the following beneficial effects:

[0015] The modified pomelo leaf residue filtration device for adsorption treatment of dyeing and printing wastewater in this utility model consists of a shell, a rotating shaft, a first filter disc, a second filter disc, and a third filter disc. The shell is inclined and its interior is divided into three areas by the first, second, and third filter discs. A motor is installed on the top of the shell, which drives the rotating shaft to rotate. The rotation of the rotating shaft causes the first, second, and third filter discs to rotate. When the first, second, and third filter discs rotate, the turbulence blades also rotate. When the waste liquid and adsorption liquid are mixed, the turbulence blades can push the mixed liquid upward, preventing adsorbed impurity particles from remaining on the first, second, or third filter discs. The adsorbed liquid will still pass through the filter holes of the first, second, and third filter discs until it is filtered by the third filter disc and discharged from the drain pipe. This device does not require the use of brush plates to clean the filter unit, avoiding the brush plates pushing impurities deep into the filter holes during cleaning, which would cause more rapid clogging.

[0020] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides a technical solution: a modified pomelo leaf residue filtration device suitable for adsorption treatment of dyeing and printing wastewater. Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 The device includes a housing 1, a fixed base 14 installed at the bottom of the housing 1, the housing 1 being inclined, a limit ring 12 installed on the inner wall of the housing 1, a first filter disc 9 inside the housing 1, a second filter disc 901 below the first filter disc 9, a third filter disc 902 below the second filter disc 901, a limit ring 12 on the outer wall of the first filter disc 9, baffles 10 installed on the upper side walls of the first filter disc 9, the second filter disc 901 and the third filter disc 902, and an annular groove 11 on the outer wall of the first filter disc 9, the second filter disc 901 and the third filter disc 902, a motor 7 installed on the top of the housing 1, a rotating shaft 8 driven by the lower output end of the motor 7, a wastewater input pipe 2 connected to the top side of the housing 1, a chemical input pipe 3 connected to one side of the housing 1, a chemical output pipe 4 connected to the side of the housing 1 away from the chemical input pipe 3, and a drain pipe 6 connected to the bottom of the housing 1.

[0022] Please see Figure 1 , Figure 2 , Figure 3 The first filter disc 9 is rotatably engaged with the limiting ring 12 via the annular groove 11. The rotating shaft 8 is sequentially fixed through the first filter disc 9, the second filter disc 901, and the third filter disc 902. The motor 7 drives the rotating shaft 8 to rotate, which in turn causes the first filter disc 9, the second filter disc 901, and the third filter disc 902 to rotate. When the first filter disc 9, the second filter disc 901, and the third filter disc 902 rotate, the turbulence-dispersing blades 10 rotate accordingly. The turbulence-dispersing blades 10 can effectively mix the waste liquid and the adsorption liquid. The mixed liquid is pushed upwards to prevent particles adsorbed with impurities from remaining on the first filter plate 9, the second filter plate 901, or the third filter plate 902. A positioning sleeve 13 is installed on the bottom inner wall of the housing 1. The positioning sleeve 13 is rotatably inserted into the rotating shaft 8 to position the rotating shaft 8. A solenoid valve 5 is installed on the agent output pipe 4. When cleaning the equipment, the solenoid valve 5 can be opened to discharge the modified pomelo leaf residue adsorbed in the chambers of the first filter plate 9, the second filter plate 901, and the third filter plate 902.

[0023] The modified pomelo leaf residue filtration device for adsorption treatment of dyeing and printing wastewater in this utility model consists of a shell 1, a rotating shaft 8, a first filter disc 9, a second filter disc 901, and a third filter disc 902. The shell 1 is in the shape of an inclined barrel, and its interior is divided into three areas by the first filter disc 9, the second filter disc 901, and the third filter disc 902.

[0024] A fixed base 14 is installed at the bottom of the housing 1, and a wastewater inlet pipe 2 is connected to the top of the housing 1 for inputting dyeing and printing wastewater. A reagent inlet pipe 3 is connected to one side of the housing 1 for inputting the adsorbent made from modified pomelo leaf residue. A limiting ring 12 is provided on the inner wall of the housing 1, and annular grooves 11 are opened on the outer walls of the first filter disc 9, the second filter disc 901, and the third filter disc 902. The first filter disc 9, the second filter disc 901, and the third filter disc 902 are rotatably engaged with the corresponding limiting rings 12. The first filter disc 9, the second filter disc 901, and the third filter disc 902 are fixed by a rotating shaft 8. Turbulence blades 10 are installed on the first filter disc 9, the second filter disc 901, and the third filter disc 902.

[0025] A motor 7 is installed on the top of the housing 1. The motor 7 drives the rotating shaft 8 to rotate. The rotation of the rotating shaft 8 causes the first filter plate 9, the second filter plate 901, and the third filter plate 902 to rotate. When the first filter plate 9, the second filter plate 901, and the third filter plate 902 rotate, the baffle blades 10 rotate with them. When the waste liquid and the adsorbent liquid are mixed, the baffle blades 10 can push the mixed liquid upward to prevent the adsorbed impurity particles from staying on the first filter plate 9, the second filter plate 901, or the third filter plate 902. The adsorbed liquid will still pass through the filter holes of the first filter plate 9, the second filter plate 901, and the third filter plate 902 until it is filtered by the third filter plate 902 and discharged from the drain pipe 6.

[0026] A chemical output pipe 4 with a solenoid valve 5 is connected to one side of the corresponding chamber of the first filter plate 9, the second filter plate 901 and the third filter plate 902. This allows the modified pomelo leaf residue adsorbed in the chambers of the first filter plate 9, the second filter plate 901 and the third filter plate 902 to be discharged during equipment cleaning.

[0027] The device eliminates the need for brushes to clean the filter unit, preventing the brushes from pushing impurities deeper into the filter pores during cleaning and causing faster clogging.
