Technical Field

[0001] The utility model relates to the technical field of waste liquid in the production of basic copper carbonate, and specifically relates to a water washing device for waste liquid in the production of basic copper carbonate. Background Technique

[0002] Basic copper carbonate is an important chemical raw material, which is widely used in many fields such as pigments, fungicides, and catalysts. A large amount of waste liquid will be generated during its production process. This waste liquid contains basic copper carbonate, various impurities, and suspended particles. In order to recover useful components and reduce environmental pollution, it is necessary to effectively treat the waste liquid, and water washing is one of the important links. The water washing link can effectively remove the suspended particles and impurities in the waste liquid, improve the purity of basic copper carbonate, and thus improve the production efficiency and product quality.

[0003] At present, when the existing water washing devices for waste liquid in the production of basic copper carbonate on the market are treating waste liquid, large particle suspended matters are difficult to effectively remove, and the impurity content in the waste liquid is still relatively high. These large particle suspended matters will affect the filtering effect during the water washing process, resulting in a reduction in water washing efficiency, thereby affecting the recovery rate of basic copper carbonate and product quality.

[0004] Therefore, a water washing device for waste liquid in the production of basic copper carbonate is needed to solve the above technical defects. Content of the Utility Model

[0005] The purpose of the utility model is to provide a water washing device for waste liquid in the production of basic copper carbonate, so as to solve the problem that large particle suspended matters will affect the filtering effect during the water washing process and lead to a reduction in water washing efficiency as mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A water washing device for waste liquid in the production of basic copper carbonate, including a pretreatment tank, an aeration tank, and a hydrocyclone. The pretreatment tank is arranged on the left side of the aeration tank, and the hydrocyclone is arranged on the right side of the aeration tank. Eight groups of rotating seats are arranged at the bottom end inside the pretreatment tank, and eight groups of rotating motors are installed at the corresponding positions at the bottom end of the pretreatment tank. The output shaft of the rotating motor is fixedly connected to the rotating seat. Filter cylinders are respectively inserted at the top ends of the rotating seats. Card steps are welded on both sides inside the pretreatment tank, and filter plates are placed at the card steps. Installation grooves are opened in the filter plates, filter meshes are placed in the installation grooves, and eight groups of slots are opened in the filter meshes. The filter cylinders are movably assembled in the slots.

[0007] Preferably, a water inlet is arranged above the outer wall of the pretreatment tank, and a first suction pump is installed between the pretreatment tank and the aeration tank. The first suction pump is connected to the pretreatment tank and the aeration tank through pipelines.

[0008] Preferably, a set of hoist motors is installed on each of the left and right sides of the outer wall of the pretreatment tank. A winding disc is arranged above the hoist motor. Guide wheels are installed on the top, outer wall and inner wall of the pretreatment tank. A suspension rope is wound around the winding disc. The suspension rope extends into the pretreatment tank through the guide wheel and is suspended at the four corners of the filter plate.

[0009] Preferably, the filter cylinder is cylindrical and is evenly distributed in the filter plate at equal intervals.

[0010] Preferably, a stirring motor is fixedly connected to the right side of the outer wall of the aeration tank. The output shaft of the stirring motor is fixedly connected to a rotating shaft, and multiple groups of stirring rods are distributed outside the rotating shaft.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows: The water washing equipment for the waste liquid in the production of basic copper carbonate not only realizes the pretreatment and filtration link, improves the subsequent water washing efficiency, realizes the lifting design for easy maintenance, reduces the labor cost required for water washing, but also realizes the staged water washing and solid-liquid separation treatment;

[0015] (1) By providing a pretreatment tank, a filter screen, a filter cylinder and a rotating motor, a pretreatment link is set before the waste liquid is washed. The waste liquid enters the pretreatment tank from the water inlet, and larger particles and impurities are removed through the filter screen to prevent them from affecting the subsequent water washing process. The small particle impurities passing through the filter screen will be adsorbed on the filter cylinder. The filter cylinder is driven to rotate by the rotating motor, so that the waste liquid below the water level line of the filter screen is further filtered. The rotary filtration can improve the contact between the filtration component and the waste liquid, and greatly improve the subsequent water washing efficiency;

[0016] (2) By providing a filter cylinder, a hoist motor, a suspension rope and a filter plate, the filter cylinder is movably assembled in the slot. After a period of filtration, the hoist motor is started. The hoist motor drives the winding disc to rotate, thereby pulling the suspension rope to wind up. The suspension rope hoists the filter plate upward, thereby driving the whole filter cylinder to rise and separating it from the rotating seat. When the filter screen rises to the top of the pretreatment tank, the filter screen and the filter cylinder can be disassembled and replaced. The lifting design is convenient for maintenance, and there is no need for personnel to enter the interior of the pretreatment tank, thus greatly reducing the labor cost required for water washing;

[0017] (3) By providing an aeration tank, a stirring motor, a drive shaft, stirring rods, a waste discharge tank, a hydrocyclone, and a sedimentation cylinder, the filtered waste liquid enters the aeration tank and is fully mixed with the clear water in the aeration tank. The drive shaft is rotated by the stirring motor, and multiple groups of stirring rods agitate the mixed aqueous solution. The basic copper carbonate in the waste liquid will come into full contact and reaction with the clear water, forming a suspension. This process helps to separate the dissolved or attached impurities, purifying the basic copper carbonate. After mixing and washing, the clear water at the bottom is discharged into the waste discharge tank through the waste discharge pipe, while the upper suspension is pumped into the hydrocyclone by the second pump. The suspended solid particles are separated from the liquid using the centrifugal force or the principle of swirl. The separated cleaning liquid is processed in the next step, and the precipitated solid particles enter the sedimentation cylinder. Description of the Drawings

[0025] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the equipment is provided with a pretreatment link before the waste liquid is washed with water. The waste liquid enters the pretreatment box 1 from the water inlet 2, and is filtered through the filter screen 9 to remove larger particles and impurities to prevent them from affecting the subsequent washing process. The small particles of impurities passing through the filter screen 9 will be adsorbed on the filter cartridge 11, and the filter cartridge 11 is driven to rotate by the rotating motor 13, so that the waste liquid below the water level line of the filter screen 9 is further filtered.

[0026] Embodiment 2: A set of hoisting motors 6 are installed on the left and right sides of the outer wall of the pretreatment box 1, and a winding reel 5 is arranged above the hoisting motor 6. The top, outer wall and inner wall of the pretreatment box 1 are all installed with guide wheels 3. The reel 5 is wound by a hanging rope 4, which extends into the pretreatment box 1 through the guide wheel 3 and is hung to the four corners of the filter plate 8. The filter cartridge 11 is cylindrical, and the filter cartridge 11 is evenly spaced in the filter plate 8.

[0027] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the filter cartridge 11 is movably assembled in the slot 10. After a period of filtering, the hoisting motor 6 is started, and the winding reel 5 is driven to rotate by the hoisting motor 6, thereby pulling the lifting rope 4 to reel up. The lifting rope 4 lifts the filter plate 8 upward, thereby driving the filter cartridge 11 as a whole to rise and separate from the rotating seat 12.

[0029] Specifically, as Figure 1 shown, the filtered waste liquid enters the aeration tank 15 and is fully mixed with the clear water in the aeration tank 15. The rotating shaft 17 is driven to rotate by the stirring motor 18, and multiple groups of stirring rods 16 agitate the mixed aqueous solution. The basic copper carbonate in the waste liquid will come into full contact and react with the clear water to form a suspension. This process helps to separate the dissolved or attached impurities, enabling the purification of the basic copper carbonate. After the mixed washing, the bottom clear water is discharged into the waste discharge tank 21 through the waste discharge pipes 20, while the upper suspension is pumped into the hydrocyclone 24 by the second pump 22. The centrifugal force or cyclone principle is used to separate the suspended solid particles from the liquid. The separated cleaning liquid is subjected to the next treatment, while the precipitated solid particles enter the sedimentation cylinder 23.

[0030] Working principle: Before the waste liquid is washed with water, a pretreatment link is set for the equipment. The waste liquid enters the pretreatment tank 1 from the water inlet 2. Larger particles and impurities are removed by filtering through the filter screen 9 to prevent them from affecting the subsequent water washing process. The small particle impurities passing through the filter screen 9 will be adsorbed onto the filter cylinder 11. The filter cylinder 11 is driven to rotate by the rotating motor 13, so that the waste liquid below the water level line of the filter screen 9 is further filtered. The filtered waste liquid is pumped into the aeration tank 15 by the first pump 14 and is fully mixed with the clear water in the aeration tank 15. The rotating shaft 17 is driven to rotate by the stirring motor 18, and multiple groups of stirring rods 16 agitate the mixed aqueous solution. The basic copper carbonate in the waste liquid will come into full contact and react with the clear water to form a suspension. This process helps to separate the dissolved or attached impurities, enabling the purification of the basic copper carbonate. After the mixed washing, the bottom clear water is discharged into the waste discharge tank 21 through the waste discharge pipes 20, while the upper suspension is pumped into the hydrocyclone 24 by the second pump 22. The centrifugal force or cyclone principle is used to separate the suspended solid particles from the liquid. The separated cleaning liquid is subjected to the next treatment, while the precipitated solid particles enter the sedimentation cylinder 23, completing the water washing process.
