Description
Technical Field
[0001] The utility model relates to the technical field of acetylene generators and is an agitating paddle of an acetylene generator. Background Art
[0002] An acetylene generator is an indispensable link in the production process of generating acetylene from calcium carbide and is the main equipment for dry acetylene production. There are multiple groups of stirring blades in the acetylene generator, which rotate continuously during the production process to prevent material blockage and ensure sufficient reaction. However, if the acetylene generator suddenly loses power or experiences other emergency shutdown failures, the agitating paddle of the acetylene generator will be unable to operate and stir, resulting in the filling and pressing of calcium carbide materials and blockage inside the generator. After such production abnormal events occur, if the agitator of the acetylene generator is directly started, there will be too much stirring resistance, the stirring motor will be overloaded and overcurrent, and the waste residue inside the acetylene generator cannot be discharged. Currently, the method for cleaning and unblocking the inside of the acetylene generator is manual material removal and slag discharge. The operators have heavy workloads, low work efficiency, high labor costs, long processing times, which affect the normal startup of the equipment, and the cleaning and unblocking operations are extremely dangerous. Summary of the Invention
[0003] The utility model provides an agitating paddle of an acetylene generator, which overcomes the above-mentioned deficiencies of the prior art and can effectively solve the problems that when the existing acetylene generator suddenly loses power or experiences other emergency shutdown failures and the agitator is directly started, there is too much stirring resistance, the stirring motor is overloaded and overcurrent, and the waste residue inside the acetylene generator cannot be discharged.
[0004] The technical solution of the utility model is realized by the following measures: An agitating paddle of an acetylene generator includes an acetylene generator body. A stirring motor is fixedly installed on the lower side of the acetylene generator body. The upper end of the output shaft of the stirring motor passes through the lower side of the acetylene generator body and is located inside the acetylene generator body. It also includes stirring blades. A plurality of stirring blades are evenly distributed at intervals along the circumference on the outer side of the upper part of the output shaft of the stirring motor. The stirring blade located at the rightmost side includes a first connecting body and a plurality of blade short sections installed together in sequence from right to left. The left side of the first connecting body is fixedly installed together with the outer side of the output shaft of the stirring motor. An installation groove with an opening facing backward is provided at the rear side of the right part of the first connecting body. A first limiting plate is fixedly installed on the right front side of the first connecting body at the position corresponding to the right side of the installation groove. Between every two adjacent blade short sections, the left part of the right blade short section is hinged to the right part of the left blade short section. A second limiting plate that contacts the front side of the rear side of the right blade short section is fixed on the right side of the left blade short section. The left end of the leftmost blade short section is hinged to the inner side of the right part of the installation groove, and the front side of the left part of the leftmost blade short section contacts the rear side of the first limiting plate.
[0005] The following is a further optimization and / or improvement of the above technical solution of the utility model:
[0006] The above-mentioned blade short section may include a second connecting body, a hinge plate, and a hinge pin. The second connecting body is in a U-shape with an opening facing backward. The right side of the front part of the second connecting body is fixedly installed with the left side of the second limiting plate. The right part of the hinge plate is fixedly installed inside the left part of the second connecting body. A vertically penetrating hinge hole is provided on the upper side of the rear part of the hinge plate. A hinge pin is rotatably installed in each hinge hole. The leftmost hinge pin is installed inside the right part of the installation groove. Between two adjacent blade short sections, the right hinge pin is installed inside the right part of the left second connecting body.
[0007] The front side of the above-mentioned first connecting body, the front side of the first limiting plate, and the front side of the second limiting plate may be coplanar. The left side of the front part of the second limiting plate extends leftward to form a third limiting plate. The rear side of the third limiting plate is fixedly connected to the front side of the second connecting body. There is a first distance between the left side of the leftmost third limiting plate and the right side of the first limiting plate. Between two adjacent second connecting bodies, there is a second distance between the left side of the right third limiting plate and the right side of the left second limiting plate.
[0008] A gap may be provided between the right side of the front part of the above-mentioned hinge plate and the left side of the leftmost third limiting plate.
[0009] The right side of the above-mentioned first connecting body, the left side of the second connecting body, and the right side of the second connecting body may all be inclined planes where the rear part is inclined leftward relative to the front part.
[0010] The rear sides of the above-mentioned first limiting plate and the second limiting plate may both be inclined planes where the left part is inclined backward relative to the right part. The included angle between the rear side and the front side of the second limiting plate is smaller than the included angle between the right side and the front side of the second connecting body.

[0012] The structure of the utility model is reasonable and compact. When a sudden power outage or shutdown occurs in the acetylene generator body, resulting in the filling and blockage of the materials inside the acetylene generator body, the output shaft of the stirring motor rotates clockwise. The stirring motor drives the first connecting body to rotate clockwise. The blade short section and the second limiting plate rotate under the resistance of the filled and blocked materials inside the acetylene generator body, that is, the right end of the blade short section rotates counterclockwise along the hinge shaft. In this way, all the blade short sections play a winding effect. After the blade short sections are wound, the torque acting on the output shaft of the stirring motor by the materials passing through the blade short sections and the second limiting plate can be reduced, and the overloading shutdown of the stirring motor will not occur. After the output shaft of the stirring motor rotates clockwise for a period of time, the agitated materials will be loosened and fall, and are discharged from the slag outlet. After operating for a period of time, the output shaft of the stirring motor is then rotated counterclockwise. The first limiting plate can limit the leftmost blade short section, and the second limiting plate can limit the right blade short sections. In this way, all the blade short sections are unfolded under the action of the resistance of the materials to form stirring blades, and the materials far from the slag outlet can be loosened. Repeating this process, the filled and blocked waste residues inside the acetylene generator body 1 can be quickly cleaned up.
[0013] When in use, the stirring paddle of this acetylene generator can quickly clean the internal material waste residues during a sudden power outage or shutdown of the acetylene generator, improve work efficiency, reduce labor costs, shorten the processing time, reduce the working intensity of operators, and avoid dangerous operations.

Specific Embodiments
[0020] The present utility model is not limited by the following embodiments, and the specific implementation manners can be determined according to the technical solutions of the present utility model and the actual situation.
[0021] In the present utility model, for the convenience of description, the description of the relative position relationship of each component is carried out according to the layout mode of the attached drawings of the specification, such as: the position relationships of front, rear, upper, lower, left, right, etc. are determined according to the layout direction of the attached drawings of the specification. Figure 1 As shown in the attached drawings, the position relationships of front, rear, upper, lower, left, right, etc. are determined according to the layout direction of the attached drawings of the specification. Figure 1 of the specification.
[0022] The present utility model will be further described below in conjunction with the embodiments and the attached drawings:
[0023] Embodiment 1: As shown in the attached drawings Figures 1 to 5 The stirring paddle of the acetylene generator includes an acetylene generator body 1. A stirring motor 2 is fixedly installed on the lower side of the acetylene generator body 1. The upper end of the output shaft of the stirring motor 2 passes through the lower side of the acetylene generator body 1 and is located inside the acetylene generator body 1. It also includes stirring blades. A plurality of stirring blades are evenly distributed at intervals along the circumference on the outer side of the upper part of the output shaft of the stirring motor 2. The stirring blade located at the rightmost side includes a first connecting body 3 and a plurality of blade short sections sequentially installed together from right to left. The left side of the first connecting body 3 is fixedly installed together with the outer side of the output shaft of the stirring motor 2. An installation groove 4 with an opening facing backward is provided at the rear side of the right part of the first connecting body 3. A first limiting plate 5 is fixedly installed on the right front side of the first connecting body 3 corresponding to the right side position of the installation groove 4. Between every two adjacent blade short sections, the left part of the right blade short section is hingedly installed with the right part of the left blade short section. A second limiting plate 6 that is in contact with the front side of the right blade short section at the rear side is fixed on the right side of the left blade short section. The left end of the leftmost blade short section is hingedly installed inside the right part of the installation groove 4, and the front side of the left part of the leftmost blade short section is in contact with the rear side of the first limiting plate 5.
[0024] According to requirements, the first connecting body 3 and the first limiting plate 5 are integrally arranged. During use, when a sudden power outage or shutdown event occurs in the acetylene generator body 1, resulting in material filling and blockage inside the acetylene generator body 1, the output shaft of the stirring motor 2 rotates clockwise. The stirring motor 2 drives the first connecting body 3 to rotate clockwise. The blade short section and the second limiting plate 6 rotate under the resistance of the filled and blocked material inside the acetylene generator body 1, that is, the right end of the blade short section rotates counterclockwise along the hinge shaft. In this way, all the blade short sections achieve a winding effect. After the blade short sections are wound, the torque acting on the output shaft of the stirring motor 2 by the material passing through the blade short sections and the second limiting plate 6 can be reduced, and the overload shutdown of the stirring motor 2 will not occur. After the output shaft of the stirring motor 2 rotates clockwise for a period of time, the agitated material will loosen and fall, and be discharged from the slag outlet. After operating for a period of time, then make the output shaft of the stirring motor 2 rotate counterclockwise. The first limiting plate 5 can limit the leftmost blade short section, and the second limiting plate 6 can limit the right blade short sections. In this way, all the blade short sections unfold under the resistance of the material to form stirring blades, which can loosen the material far from the slag outlet. Repeating this way, the filled and blocked waste residue inside the acetylene generator body 1 can be quickly cleaned up.
[0025] When in use, the stirring paddle of this acetylene generator can quickly clean the internal material waste residue during a sudden power outage or shutdown event of the acetylene generator, improve work efficiency, reduce labor costs, shorten the processing time, reduce the working intensity of operators, and avoid dangerous operations.
[0026] According to actual needs, the above-mentioned stirring paddle of the acetylene generator can be further optimized and / or improved:
[0027] Embodiment 2: As an optimization of the above embodiment, as shown in the appendix Figures 1 to 5 As shown, the blade short section includes a second connecting body 7, a hinge plate 8 and a hinge pin 9. The second connecting body 7 is in a U-shape with an opening facing backward. The right side of the front part of the second connecting body 7 is fixedly installed with the left side of the second limiting plate 6. The right part of the hinge plate 8 is fixedly installed inside the left part of the second connecting body 7. There is a through hinge hole on the upper side of the rear part of the hinge plate 8. Each hinge hole is rotatably installed with a hinge pin 9. The leftmost hinge pin 9 is installed inside the right part of the installation groove 4. Between two adjacent blade short sections, the right hinge pin 9 is installed inside the right part of the left second connecting body 7. During use, the U-shape of the second connecting body 7 with an opening facing backward can reduce the weight of the second connecting body 7, and can also limit and support the hinge plate 8, making the structure of the blade short section more compact. Through such a setting, it is not only convenient for the overall replacement of the blade short section, but also convenient for replacing the worn single second connecting body 7, which can improve the interchangeability of the second connecting body 7 and reduce the maintenance cost.
[0028] Embodiment 3: As an optimization of the above embodiment, as shown in the appendix Figures 1 to 5 As shown, the front side of the first connecting body 3, the front side of the first limiting plate 5, and the front side of the second limiting plate 6 are coplanar. The left front part of the second limiting plate 6 extends leftward to form a third limiting plate 10. The rear side of the third limiting plate 10 is fixedly connected to the front side of the second connecting body 7. There is a first distance between the left side of the leftmost third limiting plate 10 and the right side of the first limiting plate 5. Between two adjacent second connecting bodies 7, there is a second distance between the left side of the right third limiting plate 10 and the right side of the left second limiting plate 6. According to requirements, the second connecting body 7, the hinge plate 8, the second limiting plate 6, and the third limiting plate 10 are integrally provided, and the first distance and the second distance are the same. During use, through such a setting, it can be ensured that the front side of the first connecting body 3, the front side of the first limiting plate 5, and the front side of the second limiting plate 6 can rotate simultaneously under the blockage of the material, so that the blade short section can be quickly unfolded, thereby quickly achieving the stirring effect of the material. The setting of the first distance and the second distance can reduce the assembly difficulty of the stirring blades and facilitate the replacement of the blade short section.
[0029] Embodiment 4: As an optimization of the above embodiment, as shown in the appendix Figure 1 , 2 , 3, 5, there is a gap between the right front part of the hinge plate 8 and the left side of the leftmost third limiting plate 10. During use, through such a setting, a through hole that penetrates front and back is formed between the left side of the third limiting plate 10, the right front part of the hinge plate 8, and the left side of the second connecting body 7. This can reduce the weight of the blade short section, thereby reducing the load on the hinge pin 9 and avoiding the deformation of the hinge pin 9 during the stirring process of the stirring blade.
[0030] Embodiment 5: As an optimization of the above embodiment, as shown in the appendix Figures 2 to 5 As shown, the right side of the first connecting body 3, the left side of the second connecting body 7, and the right side of the second connecting body 7 are all inclined planes with the rear part inclined leftward relative to the front part. During use, when the output shaft of the stirring motor 2 rotates counterclockwise, the wound blade short section unfolds under the resistance of the material to form a stirring blade. Through such a setting, the rotation angle of the second connecting body 7 can be reduced, and it can be ensured that the second connecting body 7 can quickly rotate and then reset, that is, the blade short section unfolds to form a stirring blade, shortening the time for the blade short section to unfold to form a stirring blade.
[0031] Embodiment 6: As an optimization of the above embodiment, as shown in the appendix Figures 2 to 5As shown, the rear sides of the first limiting plate 5 and the second limiting plate 6 are both inclined planes where the left part is inclined backward relative to the right part. The included angle between the rear side surface and the front side surface of the second limiting plate 6 is smaller than the included angle between the right side surface of the second connecting body 7 and the front side surface of the second limiting plate 6. During use, the rear sides of the first limiting plate 5 and the second limiting plate 6 are both inclined planes where the left part is inclined backward relative to the right part. This can increase the contact area between the left side of the first limiting plate 5 and the right front part of the first connecting body 3, and between the left side of the second limiting plate 6 and the right front part of the second connecting body 7. Thus, the connection strength between the left side of the first limiting plate 5 and the right front part of the first connecting body 3, and between the left side of the second limiting plate 6 and the right front part of the second connecting body 7 can be improved, avoiding the phenomenon that the connection part breaks when the resistance during the stirring process is too large after the wound blade short section unfolds to form a stirring blade under the resistance of the material, and the failure rate can be reduced.
[0032] Embodiment Seven: As an optimization of the above embodiment, as shown in Figure 2 , 3 , and Figure 4, the rear side surfaces of the first connecting body 3, the second connecting body 7, and the hinge plate 8 are coplanar. During use, with such a setting, when the stirring motor 2 drives the first connecting body 3 to rotate clockwise, the front side surface of the third limiting plate 10 rotates under the resistance of filling and blocking the material inside the acetylene generator body 1, enabling the blade short section to achieve a winding effect. After the blade short section is wound, it can reduce the torque acting on the output shaft of the stirring motor 2 by the material through the third limiting plate 10, and will not cause the overload shutdown of the stirring motor 2. After the output shaft of the stirring motor 2 rotates clockwise for a period of time, the agitated material will be loosened and fall, and be discharged from the slag outlet. When it runs for a period of time and then the output shaft of the stirring motor 2 rotates counterclockwise, all the blade short sections will unfold to form stirring blades under the resistance of the material, and the material far from the slag outlet can be loosened. Repeating this way, the filled and blocked waste residue inside the acetylene generator body 1 can be quickly cleaned.
[0033] The above technical features respectively constitute the embodiments of the present invention, which have strong adaptability and implementation effects. Non-essential technical features can be added or reduced according to actual needs to meet the requirements of different situations.
