Technical Field

[0001] The utility model relates to the technical field of smoke guiding equipment, in particular to a smoke duct which is resistant to dust staining. Background Art

[0002] The production process of battery cathode materials primarily consists of precipitation, sintering, and heat treatment. Sintering is the most critical step, generating significant waste gas. This waste gas carries significant amounts of dust and volatiles. Over time, this dust aggregates and forms large clumps of dust in the flue. These clumps can potentially fall into the kiln, contaminating the materials. Furthermore, the dust can clog the flue, reducing the efficiency of the kiln's exhaust.

[0003] Therefore, how to improve the kiln flue to reduce dust accumulation in the flue is one of the issues that technical personnel in this field need to consider. Therefore, an anti-dust flue is proposed to solve the above problem. Utility Model Content

[0009] The interlayer is used for airflow, and the exhaust portion guides the airflow in the interlayer to flow along the inner wall of the inner tube.

[0010] Furthermore, there is more than one exhaust portion on the inner tube, and the multiple exhaust portions are equidistantly distributed on the inner tube.

[0011] Furthermore, the exhaust portion is an annular exhaust groove provided on the inner tube;

[0012] The annular exhaust groove is Z-shaped and is arranged along the inner diameter of the inner tube to guide the airflow to flow along the inner wall of the inner tube.

[0013] Furthermore, a connecting portion is provided in the interlayer;

[0018] The air inlet pipe is used to connect to the air supply pump;

[0019] The communicating groove is used to distribute airflow in the interlayer.

[0020] The beneficial effects of the present invention are as follows:

[0021] According to the utility model, during the sintering process of battery materials, the exhaust gas is drawn into the inner tube by the fan, and at the same time, a high-speed clean airflow is blown into the interlayer by an air supply pump, and the gas is discharged into the inner wall of the inner tube through the exhaust part arranged on the inner tube.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0035] See also Figure 1-6 The utility model discloses a dust-proof flue, comprising:

[0036] Outer tube 1;

[0037] An inner tube 2, the inner tube 2 is used to transport smoke, the inner tube 2 is sleeved inside the outer tube 1, and an interlayer 3 is provided between the outer tube 1 and the inner tube 2;

[0038] The inner tube 2 is provided with an exhaust portion 21, and the exhaust portion 21 is used to connect the inner tube 2 and the interlayer 3;

[0039] The interlayer 3 is for airflow, and the exhaust portion 21 guides the airflow in the interlayer 3 to flow along the inner wall of the inner tube 2 .

[0040] Preferably, the outer tube 1 and the inner tube 2 are cylindrical, but are not limited to the above shapes.

[0041] When the present application is in use, during the sintering process of the battery material, the exhaust gas is drawn into the inner tube 2 by the fan, and at the same time, a high-speed clean airflow is blown into the interlayer 3 by an air supply pump, and the gas is discharged into the inner wall of the inner tube 2 through the exhaust part 21 provided on the inner tube 2. The clean airflow flows rapidly along the inner tube wall, which can take away the dust and material volatiles on the inner wall of the inner tube 2, isolate the contact between the exhaust gas and the inner wall of the inner tube 2, so as to reduce dust accumulation, and have an anti-corrosion effect on corrosive exhaust gas. At the same time, it reduces the temperature of the inner tube 2 and increases the life of the range hood; in addition, there is no need for manual cleaning, which greatly reduces costs.

[0042] Specifically, there are more than one exhaust parts 21 on the inner tube 2. It should be noted that the number of exhaust parts 21 corresponds to the dust content in the flue gas, the flow rate of the air flow and the flue gas temperature under the working state, and can be flexibly set according to actual conditions. The multiple exhaust parts 21 are equidistantly distributed on the inner tube 2.

[0043] In a preferred embodiment, the exhaust portion 21 is an annular exhaust groove provided on the inner tube 2;

[0044] The annular exhaust groove is Z-shaped and is arranged along the inner diameter of the inner tube 2 to guide the airflow to flow along the inner wall of the inner tube 2 .

[0045] In the above embodiment, in order to ensure that the exhaust portion 21 guides the airflow to cover the entire inner wall of the inner tube 2, the exhaust portion 21 is provided as an annular exhaust groove. The annular exhaust groove divides the inner tube 2 into multiple sections. In order to fix the multiple sections of the inner tube 2, a connecting portion 4 is further provided in the interlayer 3.

[0046] The connecting portion 4 is used to support the inner tube 2 and is disposed in the outer tube 1 to connect multiple sections of the inner tube 2 .

[0047] Specifically, in the above arrangement, the exhaust portion 21 is arranged on one side of the inner tube 2 along the direction of smoke flow, and a guide tube with a diameter smaller than that of the inner tube 2 is provided on one side of the inner tube 2. The guide tube is sleeved on the other side of the adjacent inner tube 2. There is a gap between the guide tube and the inner tube 2, and the gap is an annular exhaust groove. The annular exhaust groove is used to connect the interlayer 3 and the inner tube 2, so that a fast and clean airflow enters the inner tube 2 from the interlayer 3 and flows along the inner wall of the inner tube 2 to prevent dust in the smoke from adhering to the inner tube 2.

[0048] It should be further explained that the air inlet end of the inner tube 2 is provided with an air inlet portion 5;

[0049] The air inlet 5 corresponds to the interlayer 3 and is used to allow an airflow with a flow rate greater than that of the smoke to enter the interlayer 3 .

[0050] Specifically, the air intake portion 5 includes an air intake pipe 51 and a communication groove 52;

[0051] The air inlet pipe 51 is used to connect to the air supply pump. Preferably, the air supply pump is a blower or other equipment with equivalent functions that can be easily thought of by those skilled in the art.

[0052] The communication grooves 52 are used to distribute airflow within the interlayer 3 .

[0053] When the present invention is in use, the high-speed airflow flows rapidly along the side wall of the inner tube 2, and the flow rate is greater than the flue gas flow rate, which can isolate the flue gas from contacting the inner tube 2, and can prevent the corrosive flue gas from corroding, thereby extending the service life of the inner tube 2;

[0054] Secondly, the gas introduced into the interlayer 3 can be selected from high-temperature, normal-temperature or low-temperature air or other gases, and the temperature of the flue outer wall and the fan can be freely selected to increase or decrease. Generally, normal-temperature gas is selected to reduce the temperature of the flue outer wall;

[0055] The high-speed airflow is blown into the interlayer 3 to control the airflow velocity. The variable frequency fan can be selected to blow in the air, and the flow velocity and wind pressure of the high-speed airflow into the interlayer 3 can be controlled. The fan frequency can be adjusted to select the best cleaning effect and the optimal energy consumption conditions.

[0056] Finally, the high-speed gas blown into the interlayer 3 and the flue gas from the inner tube 2 are uniformly extracted by the exhaust fan at the end of the inner tube 2, which can reduce the temperature of the exhaust fan and increase the service life of the fan.

[0057] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0058] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features specified as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0059] In addition, "plurality" means two or more.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
