Description

Technical Field

[0001] This utility model relates to the field of flocculant dosing technology, and specifically discloses a quantitative flocculant dosing device for experimental treatment of silicon cutting wastewater. Background Technology

[0002] Wastewater from silicon cutting processes contains large amounts of suspended solids such as silicon powder and corundum, as well as organic matter, characterized by high suspended solids content, complex composition, and difficulty in degradation. Direct discharge without effective treatment will cause serious environmental pollution. Polyaluminum chloride, as a commonly used powdered coagulant, has advantages such as good flocculation effect and wide applicability, and is widely used in industrial wastewater treatment.

[0003] Currently, flocculants are often added manually in the laboratory. However, manual measurement of polyaluminum chloride flocculants is prone to errors, affecting the accuracy of the experiment. Frequent manual operation is time-consuming and cannot achieve continuous multi-group comparative experiments. Utility Model Content

[0004] This invention proposes a quantitative flocculant dosing device for treating wastewater from silicon cutting processes. This device can quantitatively and uniformly dispense flocculant, preventing errors that could affect experimental accuracy. By automatically dispensing flocculant, the device can improve the efficiency of flocculant dosing, enabling continuous multi-group comparative experiments.

[0005] This utility model is implemented as follows: a quantitative flocculant dosing device for treating wastewater from silicon cutting processes includes a shell, and a quantitative dosing mechanism is provided inside the shell.

[0006] The quantitative dispensing mechanism includes a turntable rotatably connected inside the outer shell. The outer wall of the turntable is in close contact with the inner wall of the outer shell. A quantitative hole is opened through the upper end face of the turntable. Multiple adjusting cylinders are arranged sequentially inside the quantitative hole. The multiple adjusting cylinders are tightly fitted together. The outer wall of the outermost adjusting cylinder is tightly fitted with the inner wall of the quantitative hole. A storage tank is fixedly connected to the upper end face of the outer shell. The lower end of the storage tank is connected to the outer shell and is located directly above one of the quantitative holes.

[0007] In a preferred embodiment of the experimental flocculant quantitative dosing device for treating silicon industry cutting wastewater according to this utility model, an installation plate is fixedly connected to the upper end of the storage tank, and a spiral conveying rod is rotatably connected to the lower end face of the installation plate. The spiral conveying rod is driven by a first drive motor installed on the upper end face of the installation plate.

[0008] In a preferred embodiment of the experimental flocculant quantitative dosing device for treating silicon industry cutting wastewater according to this utility model, the inner wall of the quantitative orifice and the inner and outer walls of the multiple adjusting cylinders are all fixedly connected with mutually matching fixed magnets.

[0009] As a preferred embodiment of the experimental flocculant quantitative dosing device for treating silicon industry cutting wastewater according to this utility model, a second drive motor is installed on the lower end face of the outer shell, and the output end of the second drive motor is fixedly connected to the turntable.

[0010] As a preferred embodiment of the experimental flocculant quantitative dosing device for treating silicon industry cutting wastewater according to this utility model, the upper end face of the outer shell is provided with a cover plate.

[0011] As a preferred embodiment of the experimental flocculant quantitative dosing device for treating silicon industry cutting wastewater according to this utility model, the lower end face of the outer shell is connected to a discharge pipe located directly below another quantitative orifice.

[0012] The beneficial effects of this utility model are:

[0013] The flocculant is pushed into the metering orifice located directly below the storage tank by a rotating screw conveyor. The flocculant is metered through the metering orifice. Then, the turntable drives the two metering orifices to switch positions, allowing the flocculant to be discharged from the metering orifice by gravity. This ensures that the flocculant is metered and evenly added, preventing errors that could affect the accuracy of the experiment. By automatically adding the flocculant, the efficiency of flocculant addition can be improved, enabling continuous multi-group comparative experiments.

[0014] When the capacity of the metering orifice needs to be adjusted, the innermost adjusting cylinder is removed from the metering orifice to increase its capacity. Conversely, adjusting cylinders are installed into the metering orifice to decrease its capacity, thus adjusting the capacity of the metering orifice. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0021] Please see Figure 1-3 A quantitative flocculant dosing device for treating wastewater from silicon cutting processes includes a housing 1, and a quantitative dosing mechanism is provided inside the housing 1.

[0022] The quantitative dispensing mechanism includes a turntable 2 rotatably connected inside the outer shell 1. The outer wall of the turntable 2 is in close contact with the inner wall of the outer shell 1. A quantitative hole 3 is opened through the upper end face of the turntable 2. Multiple adjusting cylinders 4 are arranged sequentially inside the quantitative hole 3. The multiple adjusting cylinders 4 are tightly connected to each other. The outer wall of the outermost adjusting cylinder 4 is tightly connected to the inner wall of the quantitative hole 3. A storage tank 5 is fixedly connected to the upper end face of the outer shell 1. The lower end of the storage tank 5 is connected to the outer shell 1 and is located directly above one of the quantitative holes 3.

[0023] In this embodiment: During use, the flocculant is placed in the storage tank 5, and then the screw conveyor 7 rotates. The rotating screw conveyor 7 pushes the flocculant into the metering hole 3 located directly below the storage tank 5. After the metering hole 3 is filled with flocculant, the turntable 2 rotates. The turntable 2 drives the two metering holes 3 to switch positions. Since the outer wall of the turntable 2 is in close contact with the inner wall of the outer shell 1, when the turntable 2 rotates, the outer shell 1 scrapes off the flocculant that exceeds the metering hole 3, so that the amount of flocculant in the metering hole 3 is fixed. Then, the flocculant falls from the metering hole 3 into the discharge pipe 12 by gravity and is discharged through the discharge pipe 12. In this way, the flocculant is quantitatively and evenly added to prevent errors and affect the accuracy of the experiment. By automatically adding flocculant, the efficiency of adding flocculant can be improved, so as to realize multiple sets of comparative experiments.

[0024] When the capacity of the metering orifice 3 needs to be adjusted, the innermost adjusting cylinder 4 is removed from the metering orifice 3 in sequence to increase the capacity of the metering orifice 3. Conversely, the adjusting cylinder 4 can be installed into the metering orifice 3 to decrease the capacity of the metering orifice 3, thereby adjusting the capacity of the metering orifice 3.

[0025] As a technical optimization of this utility model, an installation plate 6 is fixedly connected to the upper end of the storage tank 5, and a spiral conveying rod 7 is rotatably connected to the lower end face of the installation plate 6. The spiral conveying rod 7 is driven by a first drive motor 8 installed on the upper end face of the installation plate 6.

[0026] In this embodiment: the first drive motor 8 can drive the screw conveyor 7 to rotate. The rotating screw conveyor 7 can accelerate the feeding speed of flocculant while preventing flocculant blockage.

[0027] As a technical optimization of this utility model, the inner wall of the metering orifice 3 and the inner and outer walls of the multiple adjusting cylinders 4 are all fixedly connected with matching fixed magnets 9.

[0028] In this embodiment, the adjusting cylinder 4 can be attracted and fixed by multiple fixed magnets 9.

[0029] As a technical optimization of this utility model, a second drive motor 10 is installed on the lower end face of the outer shell 1, and the output end of the second drive motor 10 is fixedly connected to the turntable 2.

[0030] In this embodiment, the second drive motor 10 can drive the turntable 2 to rotate.

[0031] As a technical optimization of this utility model, a cover plate 11 is provided on the upper end surface of the outer shell 1.

[0032] In this embodiment, a cover plate 11 is provided on the upper end face of the outer shell 1, which facilitates the installation or removal of the adjusting cylinder 4.

[0033] As a technical optimization of this utility model, the lower end face of the outer shell 1 is connected to a discharge pipe 12 located directly below another metering hole 3.

[0034] In this embodiment, the flocculant can be discharged from the outer shell 1 through the discharge pipe 12.

[0035] The working principle and usage process of this utility model are as follows: When in use, the flocculant is placed in the storage tank 5, and then the first drive motor 8 drives the spiral conveyor 7 to rotate. The rotating spiral conveyor 7 pushes the flocculant into the metering hole 3 located directly below the storage tank 5. After the metering hole 3 is filled with flocculant, the second drive motor 10 drives the turntable 2 to rotate. The turntable 2 drives the two metering holes 3 to switch positions. Since the outer wall of the turntable 2 is in close contact with the inner wall of the outer shell 1, when the turntable 2 rotates, the outer shell 1 scrapes off the flocculant that exceeds the metering hole 3, so that the amount of flocculant in the metering hole 3 is fixed. Then, the flocculant falls from the metering hole 3 into the discharge pipe 12 by gravity and is discharged through the discharge pipe 12, thereby quantitatively and evenly dispensing the flocculant.
