Description

Technical Field

[0001] The utility model belongs to the technical field of pigment production wastewater treatment, and in particular relates to a pigment production device for efficient wastewater treatment. Background Art

[0002] During the pigment production process, a large amount of pigment wastewater with high nitrogen content and high COD concentration will be produced. At present, the treatment operation for this type of pigment wastewater is generally based on direct dumping and adding coagulants for precipitation treatment. The coagulation sedimentation tank treatment method used for pigment wastewater has the advantages of simple treatment operation and good precipitation removal effect, but on the other hand, due to the inappropriate addition of coagulants, impurities in the wastewater are not fully precipitated, and finally the treated water body does not meet the standards.

[0003] In the Chinese patent with publication number CN 206872497 U, a high-efficiency sewage treatment device for pigment production is provided, which can be used to improve the coagulation and sedimentation effect by expanding the effective addition area of ​​the coagulant. The utility model has the advantages of simple and effective structure, convenient and uniform coagulant addition operation and good coagulation and sedimentation effect;

[0004] However, the above device has the following problems during use:

[0005] The coagulant comes into contact with the sewage generated by the pigment production from the dispersion disk, thereby mixing the coagulant with the sewage quickly and evenly. However, during the mixing process, the sewage will come into contact with the pigment inside the dispersion disk, causing the coagulant to contact the sewage prematurely, and the amount of sewage in contact with the coagulant inside the dispersion disk is small, which will cause part of the coagulant to adhere to the sewage and adhere to the inner wall of the dispersion disk, causing the internal channel of the dispersion disk to be blocked. Utility Model Content

[0006] The purpose of the utility model is to provide a pigment production device for efficient sewage treatment to solve the problems raised by the above-mentioned background technology.

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions, including a sewage treatment tank, a material spreading motor, and a material spreading mechanism, wherein the material spreading mechanism is connected to a material spreading main pipe and a material spreading branch pipe;

[0008] The bottom of the material spreading branch pipe is provided with a material spreading port, a spherical cavity is provided in the material spreading branch pipe, and a sphere is clamped in the spherical cavity;

[0009] An air supply mechanism is installed on the top of the material spreading main pipe, the air supply mechanism is connected to the air intake pipe, the air intake pipe is connected to the first exhaust pipe and the second exhaust pipe, and the first exhaust pipe and the second exhaust pipe are respectively located on both sides of the spherical cavity.

[0010] Preferably, the material spreading mechanism comprises a coagulant storage chamber, and the storage chamber is connected to a plurality of material spreading branches.

[0011] Preferably, the size of the sphere is larger than the size of the channels at both ends of the spherical cavity.

[0012] Preferably, a first valve and a second valve are installed at the first exhaust pipe and the second exhaust pipe respectively, and only one of the first valve and the second valve can be in an open state.

[0013] Preferably, the air intake pipe is connected to the third exhaust pipe, a third valve is installed at the third exhaust pipe, the third valve is in an open state, the third exhaust hole of the third exhaust pipe is aligned with the driving blades in the mixing mechanism, and the gas discharged from the third exhaust hole can drive the driving blades to rotate.

[0014] Preferably, the driving blade is fixedly connected to the guide sleeve, the guide sleeve is fixedly connected to the mixing blade, and the inner diameter of the guide sleeve is greater than or equal to the inner diameter of the end of the discharge pipe.

[0015] Preferably, a rotating shaft is fixedly installed in the middle of the mixing blade, the rotating shaft is rotatably connected to the material spreading branch pipe, and the size of the rotating shaft is smaller than the inner diameter size at the end of the discharge pipe.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The utility model arranges a spherical cavity, a sphere and other components inside the spreading branch pipe. After adding a sufficient amount of coagulant, the channel at the top of the spherical cavity is blocked to prevent excess coagulant from contacting sewage. At the same time, the circulating gas introduced into the spreading branch pipe can accelerate the falling speed of the coagulant, and the coagulant with adhesion is blown away by the power of air to ensure the smoothness of the discharge pipe.

[0018] 2. The utility model sets a third exhaust pipe at the bottom of the spreading branch pipe, which is connected to the air intake pipe to provide rotational force to the driving blades and the mixing blades. The coagulant can be quickly mixed with the surrounding sewage after passing through the guide sleeve and then rotating the mixing blades, thereby avoiding the coagulant remaining at the bottom of the spreading branch pipe.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Reference Figure 1-Figure 5 A pigment production device for efficient sewage treatment includes a sewage treatment tank 1, a spreading motor 2, and a spreading mechanism. The spreading mechanism is connected to a spreading main pipe 3 and a spreading branch pipe 4. The spreading mechanism can send a coagulant from a discharge pipe into the sewage treatment tank 1. Wastewater generated in the pigment production process is stored in the sewage treatment tank 1. A large amount of particulate impurities are mixed in the wastewater. After these impurities come into contact with the coagulant, they are mixed and fall to the bottom of the sewage treatment tank 1, thereby achieving the purpose of preliminarily removing particulate impurities in the pigment. Specifically, the spreading mechanism includes a coagulant storage chamber, which is connected to a plurality of spreading branch pipes 4 and is discharged through a discharge pipe in the spreading branch pipe 4.

[0027] It should be noted that a spreading port 401 is provided at the bottom of the spreading branch pipe 4, a spherical cavity 402 is provided in the spreading branch pipe 4, a sphere 403 is clamped in the spherical cavity 402, and the size of the sphere 403 is larger than the size of the channels at both ends of the spherical cavity 402, so that a channel at the top of the spherical cavity 402 can be opened and closed. When the channel is opened, the coagulant can enter the spreading branch pipe 4 and finally be discharged from the spreading port 401. When the channel is closed, the water in the sewage treatment tank 1 and the coagulant storage cavity can be isolated to prevent the remaining coagulant from being wetted;

[0028] In a further embodiment, an air supply mechanism is installed on the top of the material spreading main pipe 3, and the air supply mechanism is connected to the air intake pipe 8, and the air intake pipe 8 is connected to the first exhaust pipe 5 and the second exhaust pipe 6. The first exhaust pipe 5 and the second exhaust pipe 6 are respectively located on both sides of the spherical cavity 402. The first exhaust pipe 5 and the second exhaust pipe 6 are respectively installed with a first valve and a second valve. Only one of the first valve and the second valve can be in an open state. When the second valve at the second exhaust pipe 6 is opened, the gas can enter the upper side of the spherical cavity 402. At this time, the gas will squeeze the sphere 40 3. The channel at the top of the spherical cavity 402 is opened. At this time, the coagulant can enter the spreading port 401 in the spreading branch pipe 4 from the coagulant storage cavity. At the same time, the flow of the gas can accelerate the falling speed of the coagulant. On the contrary, the first valve in the first exhaust pipe 5 is opened, which will push the sphere 403 upward and close the channel at the top of the spherical cavity 402. At this time, the gas enters the lower half of the spreading branch pipe 4, pushing the residual coagulant therein and the sewage entering therein, so that the two are quickly mixed, and the coagulant is discharged from the spreading port 401 as soon as possible;

[0029] In a further embodiment, the air intake pipe 8 is connected to the third exhaust pipe 7, and a third valve is installed at the third exhaust pipe 7. The third valve is in an open state. After the air supply mechanism is started, the gas can be discharged from the third exhaust hole through the third valve. The third exhaust hole of the third exhaust pipe 7 is aligned with the driving blade 901 in the mixing mechanism 9. The gas discharged from the third exhaust hole can drive the driving blade 901 to rotate. The driving blade 901 is fixedly connected to the guide sleeve 902, and the guide sleeve 902 is fixedly connected to the mixing blade 903. The inner diameter of the guide sleeve 902 is greater than or equal to the inner diameter of the end of the discharge pipe. A rotating shaft is fixedly installed in the middle of the mixing blade 903. The rotating shaft is rotatably connected to the material spreading branch pipe 4, and the size of the rotating shaft is smaller than the inner diameter at the end of the discharge pipe.
