Description

Technical Field

[0001] The utility model belongs to the technical field of fuel cells, and particularly relates to a catalyst slurry dispersing device. Background Art

[0002] A fuel cell is a chemical device that converts the chemical energy of a fuel directly into electrical energy. It is also called an electrochemical generator. It is the fourth power generation technology after hydropower, thermal power generation, and atomic power generation. It has the advantages of high energy conversion efficiency, clean reaction, reliable operation, long service life, less radiation, a wide range of raw materials, and easy construction. It has been widely used in the automotive industry, energy generation, shipbuilding industry, aerospace, and household power supply industries. Catalyst slurry is one of the important components of fuel cells. During the production and processing of fuel cells, the catalyst slurry needs to be stirred. The catalyst slurry is dispersed by a dispersion device to avoid agglomeration of the catalyst slurry during mixing and ensure the quality of the produced catalyst slurry. However, it still has the following disadvantages in actual use:

[0003] The utility model with publication number CN217725198U discloses a catalyst slurry dispersing device, wherein a motor is fixedly installed on the top of the dispersing tank, a rotating rod is fixedly connected to the output end of the motor, the bottom of the rotating rod extends into the interior of the dispersing tank, and a mixing disk with a spiral design is fixedly connected to the outer surface of the rotating rod and located inside the dispersing tank; a conveying mechanism is arranged on one side of the dispersing tank, and the dispersing device conveys the catalyst slurry at the bottom of the dispersing tank to the top of the dispersing tank through the conveying mechanism, so that the mixing and dispersion of the catalyst slurry are more sufficient and stratification is avoided, and the conveying mechanism usually needs to use a driving mechanism such as a conveying pump, which increases the cost and maintenance expenses of the dispersing device, and some catalyst slurries are relatively viscous and easily adhere to the inner wall of the conveying pipeline, which is not convenient for cleaning and increases the labor intensity of the staff;

[0004] When the catalyst slurry dispersion device is in use, it is mostly dispersed by a breaking up mechanism to prevent the slurry from agglomerating during mixing. However, when the device drives the catalyst slurry to flow and mix at high speed, the slurry with small particles is difficult to be quickly broken up by the rotating breaking up mechanism, which reduces the mixing and dispersion efficiency. Utility Model Content

[0005] The utility model aims to provide a catalyst slurry dispersing device, which solves the problem that the catalyst slurry dispersing device circulates the catalyst slurry by setting a conveying mechanism through a dispersion barrel and a top cover. Although the mixing and dispersion of the catalyst slurry are more sufficient and stratification is avoided, the cost and maintenance expenses of the dispersing device are increased, and some catalyst slurries are relatively viscous and easily adhere to the inner wall of the conveying pipeline, which is not convenient for cleaning and increases the labor intensity of the staff. The slurry with small particles is difficult to be quickly dispersed by the rotating dispersion mechanism.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a catalyst slurry dispersing device, comprising a dispersing barrel and a top cover, wherein an inverted truncated cone-shaped tube is suspended in the dispersing barrel, the top cover is clamped and fixed on the top of the dispersing barrel, a dispersing frame is arranged at the bottom of the top cover, and the dispersing frame is attached to the top of the inverted truncated cone-shaped tube;

[0008] When the catalyst slurry is mixed and dispersed, the high-speed rotating catalyst slurry will be subjected to a certain centrifugal force, causing the catalyst slurry to move outward. The catalyst slurry on the inside of the inverted conical tube can move upward along the inverted conical tube under the action of centrifugal force, and fall through the gap between the top of the inverted conical tube and the inner wall of the dispersion barrel, and enter the inverted conical tube again as the catalyst slurry in the inverted conical tube moves upward, so that the catalyst slurry circulates inside and outside the inverted conical tube to avoid stratification of the catalyst slurry, simplify the device structure, reduce costs and maintenance expenses, and facilitate cleaning by staff. When the catalyst slurry passes through the top of the inverted conical tube under the action of centrifugal force, the slurry with small particles can be dispersed through the screen of the dispersion rack, thereby improving the dispersion efficiency of the device.

[0009] Furthermore, a feed pipe is welded through the top of the outer circumference of the dispersion barrel, a discharge pipe is welded through the bottom of the dispersion barrel, and a support frame is welded and fixed to the bottom of the outer circumference of the dispersion barrel;

[0010] The catalyst slurry can be dispersed through the dispersion barrel to avoid agglomeration of the catalyst slurry during the mixing process, thereby ensuring the quality of the produced catalyst slurry.

[0011] Furthermore, a support rod is welded and fixed to the outer circumference of the inverted frustum-shaped tube, and the other end of the support rod is clamped to the inner wall of the dispersion barrel, and the inverted frustum-shaped tube is located at the bottom of the feed pipe;

[0012] During the high-speed mixing and dispersion process of the catalyst slurry, the catalyst slurry can move upward along the inverted conical tube under the action of centrifugal force, and fall through the gap between the inverted conical tube and the inner wall of the dispersion barrel at the top of the inverted conical tube, and enter the inverted conical tube again as the catalyst slurry in the inverted conical tube moves upward, so that the catalyst slurry circulates inside and outside the inverted conical tube, avoiding stratification of the catalyst slurry, simplifying the device structure, reducing costs and maintenance expenses, and facilitating cleaning by staff.

[0013] Furthermore, a dispersion motor is clamped in the center of the top of the top cover, a rotating rod is clamped at the bottom of the dispersion motor, and the rotating rod penetrates and is inserted into the top of the top cover;

[0014] The dispersion motor can drive the rotating rod to rotate, which further drives the dispersion disk to rotate at a high speed, so as to shear and disperse the catalyst slurry, thereby improving the automation degree of the dispersion device.

[0015] Furthermore, a screen is inserted through the top of the dispersion rack, the rotating rod is inserted through the center of the top of the dispersion rack, and a plurality of dispersion discs are fixed to the outer circumference of the rotating rod from top to bottom, and the plurality of dispersion discs are inserted into the inner side of the inverted frustum cone tube;

[0016] When the catalyst slurry moves upward along the inverted frustum-shaped tube under the centrifugal force, when the catalyst slurry moves to the top of the inverted frustum-shaped tube, the slurry with small particles can be dispersed through the screen, thereby improving the dispersion efficiency of the device.

[0017] The utility model has the following beneficial effects:

[0018] The utility model solves the problem that the dispersion device transports the catalyst slurry at the bottom of the dispersion tank to the high point of the dispersion tank through the conveying mechanism, so that the mixing and dispersion of the catalyst slurry is more sufficient and stratification is avoided. The conveying mechanism usually needs to use a driving mechanism such as a conveying pump, which increases the cost and maintenance expenses of the dispersion device, and some catalyst slurries are relatively viscous and easily adhere to the inner wall of the conveying pipe, which is not convenient for cleaning and increases the labor intensity of the staff. In the process of high-speed mixing and dispersion of the catalyst slurry, the catalyst slurry in the inverted conical tube moves upward along the inverted conical tube under the action of centrifugal force, and falls through the gap between the inverted conical tube and the inner wall of the dispersion barrel at the top of the inverted conical tube, and enters the inverted conical tube again with the upward movement of the catalyst slurry in the inverted conical tube, so that the catalyst slurry circulates inside and outside the inverted conical tube, avoiding stratification of the catalyst slurry, and simplifying the device structure, reducing the cost and maintenance expenses, and facilitating cleaning by the staff.

[0019] The utility model provides a dispersion barrel and a top cover to solve the problem that when a catalyst slurry dispersion device is used, most of the time, it is dispersed by a dispersing mechanism to prevent the slurry from agglomerating into lumps during mixing. However, when the device drives the catalyst slurry to flow and mix at a high speed, the slurry with small particles agglomerated is difficult to be quickly dispersed by the rotating dispersing mechanism, thereby reducing the mixing and dispersion efficiency. When the catalyst slurry is moved upward along the inverted frustum cone-shaped tube by centrifugal force, after the catalyst slurry moves to the top of the inverted frustum cone-shaped tube, the centrifugal force causes the slurry with small particles to be dispersed through the dispersion rack, thereby preventing the slurry with small particles agglomerated from being difficult to disperse through the dispersion disk, thereby reducing the dispersion efficiency.

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] See also Figure 1-5 As shown, the utility model is a catalyst slurry dispersing device, comprising a dispersing barrel 1 and a top cover 2, wherein an inverted truncated cone-shaped tube 102 is suspended in the dispersing barrel 1, the top cover 2 is clamped and fixed on the top of the dispersing barrel 1, a dispersing frame 203 is arranged at the bottom of the top cover 2, and the dispersing frame 203 is attached to the top of the inverted truncated cone-shaped tube 102;

[0029] When the catalyst slurry is mixed and dispersed, the high-speed rotating catalyst slurry moves upward along the inner wall of the inverted conical tube 102 under the action of centrifugal force, and falls through the gap between the top of the inverted conical tube 102 and the inner wall of the dispersion barrel 1, and the catalyst slurry at the bottom of the dispersion barrel 1 enters the inverted conical tube 102 again as the catalyst slurry in the inverted conical tube 102 moves upward, so that the catalyst slurry circulates inside and outside the inverted conical tube 102, and when the catalyst slurry passes through the top of the inverted conical tube 102 under the action of centrifugal force, the slurry with small particles is dispersed through the screen 204 of the dispersion rack 203.

[0030] Among them Figure 1-4 As shown, a feed pipe 103 is welded through the top of the outer circumference of the dispersion barrel 1, a discharge pipe 104 is welded through the bottom of the dispersion barrel 1, a support frame 101 is welded and fixed to the bottom of the outer circumference of the dispersion barrel 1, a support rod 105 is welded and fixed to the outer circumference of the inverted frustum cone-shaped tube 102, and the other end of the support rod 105 is clamped to the inner wall of the dispersion barrel 1, and the inverted frustum cone-shaped tube 102 is located at the bottom of the feed pipe 103;

[0031] When the catalyst slurry is mixed and dispersed, a certain amount of catalyst slurry is poured into the dispersion barrel 1 through the feed pipe 103 until the liquid level is slightly lower than the top of the inverted conical tube 102. During the high-speed mixing and dispersion of the catalyst slurry, the catalyst slurry moves upward along the inverted conical tube 102 under the action of centrifugal force, and falls through the gap between the inverted conical tube 102 and the inner wall of the dispersion barrel 1 at the top of the inverted conical tube 102. The catalyst slurry at the bottom of the dispersion barrel 1 enters the inverted conical tube 102 again as the catalyst slurry in the inverted conical tube 102 moves upward, so that the catalyst slurry circulates inside and outside the inverted conical tube 102 to avoid stratification of the catalyst slurry. After the mixing and dispersion of the catalyst slurry is completed, the discharge pipe 104 is opened to pour out the catalyst slurry, and the top cover 2 and the inverted conical tube 102 are removed, and each structure of the dispersion device is cleaned.

[0032] Among them Figure 1 , 2 As shown in , 5, a dispersion motor 201 is clamped at the center of the top of the top cover 2, a rotating rod 205 is clamped at the bottom of the dispersion motor 201, the rotating rod 205 penetrates and is inserted into the top of the top cover 2, a screen 204 is clamped at the top of the dispersion rack 203, the rotating rod 205 penetrates and is clamped at the center of the top of the dispersion rack 203, and a plurality of dispersion discs 202 are clamped and fixed on the outer circumference of the rotating rod 205 from top to bottom, and the plurality of dispersion discs 202 are inserted into the inner side of the inverted frustum cone tube 102;

[0033] During the high-speed mixing and dispersion process of the catalyst slurry, the dispersion motor 201 drives the rotating rod 205 to rotate, which further drives the dispersion disk 202 to rotate at a high speed to shear and disperse the catalyst slurry. The catalyst slurry moves upward along the inverted frustum-shaped tube 102 under the centrifugal force. When the catalyst slurry moves to the top of the inverted frustum-shaped tube 102, the slurry with small particles is dispersed through the screen 204.

[0034] The specific working principle of the utility model is as follows: when the catalyst slurry is mixed and dispersed, a certain amount of catalyst slurry is poured into the dispersion barrel 1 through the feed pipe 103 until the liquid level is slightly lower than the top of the inverted truncated cone tube 102. During the high-speed mixing and dispersion of the catalyst slurry, the dispersion motor 201 drives the rotation of the rotating rod 205, and further drives the dispersion disk 202 to rotate at a high speed to shear and disperse the catalyst slurry. The catalyst slurry moves upward along the inner wall of the inverted truncated cone tube 102 under the centrifugal force, and the slurry with small particles is agglomerated through the screen 204 at the top of the inverted truncated cone tube 102. Dispersion is carried out. The catalyst slurry passing through the screen 204 falls through the gap between the inverted conical tube 102 and the inner wall of the dispersion barrel 1 under the action of centrifugal force and gravity. The catalyst slurry at the bottom of the dispersion barrel 1 enters the inverted conical tube 102 again as the catalyst slurry in the inverted conical tube 102 moves upward, so that the catalyst slurry circulates inside and outside the inverted conical tube 102 to avoid stratification of the catalyst slurry. After the catalyst slurry is mixed and dispersed, the discharge pipe 104 is opened to pour out the catalyst slurry, and the top cover 2 and the inverted conical tube 102 are removed, and each structure of the dispersion device is cleaned.
