[0002] Currently, the production of acetylene black requires a large amount of acetylene gas, which is mainly produced by the reaction of calcium carbide and water. However, the reaction of calcium carbide and water in the acetylene generator produces a large amount of calcium carbide slurry, which is discharged and transported to a sedimentation tank. Currently, the calcium carbide slurry is transported via an aqueduct, utilizing a slope to allow free flow from higher to lower elevations. During transport, some calcium carbide slurry settles and adheres to the bottom of the aqueduct. As the operating time increases, the amount of calcium carbide slurry adhering to the bottom of the aqueduct accumulates, requiring regular manual dredging. If not handled promptly, the calcium carbide slurry will overflow from the aqueduct during transport, polluting the environment. Utility Model Content

[0035] The following reference Figures 1 to 5This application describes a slurry conveying device according to some embodiments.

[0036] See Figures 1 to 4 As shown, an embodiment of this application provides a slurry conveying device 1, including: an aqueduct 1, a first driving device 2, a first transmission mechanism 3, a scraping component 4, a second driving device 5, and a cleaning brush 6; wherein, a drain outlet is formed at one end of the aqueduct 1 along its length direction.

[0037] The first driving device 2 is used to drive the first transmission mechanism 3 to drive the scraping member 4 to make a circular motion in the plane formed by the length direction of the aqueduct 1 and the depth direction of the aqueduct 1. During the motion, the scraping member 4 can scrape the carbide slag deposited at the bottom of the aqueduct 1 to the sewage outlet and discharge it from the sewage outlet, or disperse the carbide slag in the slurry and carry it away by the flowing slurry.

[0038] Along the length of the aqueduct 1, a cleaning brush 6 is disposed on the side of one end of the aqueduct 1, and the cleaning brush 6 is connected to the drive end of the second drive device 5. The second drive device 5 is used to drive the cleaning brush 6 to rotate, so as to clean the scraping member 4 during the process of flipping from the bottom of the aqueduct 1 to the top of the aqueduct 1.

[0039] As can be seen from the structure described above, the first driving device 2 drives the scraping component 4 to move through the first transmission mechanism 3. In particular, the direction of movement of the scraping component 4 can be the same as the direction of flow of the thin slurry (of course, it is not limited to this, the direction of movement of the scraping component 4 can also be opposite to the direction of flow of the thin slurry, depending on the actual needs). The thin slurry flows from left to right, and the scraping component 4 pushes the carbide slag deposited at the bottom and sides of the aqueduct 1 from left to right toward the discharge port, thereby discharging the carbide slag from the aqueduct 1 through the discharge port. In addition, the second driving device 5 can be used to drive the cleaning brush 6 to rotate, thereby cleaning the scraping component 4 and ensuring that the scraping component 4 works normally.

[0040] As can be seen, the slurry conveying device 1 provided in this application can clean the deposited carbide slag on its own without manual cleaning, which greatly improves work efficiency and ensures the safety of workers.

[0041] Furthermore, preferably, the cleaning brush 6 is located on the side close to the first transmission mechanism 3. Of course, it is not limited to this. The cleaning brush 6 can also be located on the front side or the lower side of the first transmission mechanism 3, depending on the actual needs.

[0042] It should be noted that, not only along the length of the aqueduct 1 as described above, the cleaning brush 6 is located on the side of one end of the aqueduct 1, but it can also be located in other positions, such as the top of the aqueduct 1, to clean the scraping member 4 as it moves along the top of the aqueduct 1; in another embodiment, the two cleaning brushes 6 are located on opposite sides of the first transmission mechanism 3, depending on the actual needs.

[0043] Furthermore, it should be noted that: preferably, the bottom of one end of the aqueduct 1 along its length is completely through, that is, this open end serves as a sewage outlet. Of course, it is not limited to this, and it is not limited to the above-mentioned design that one end of the aqueduct 1 along its length is through; it can also be closed. Preferably, a sewage outlet is opened at the bottom of this end of the aqueduct 1 as a discharge outlet. In addition, the other end of the aqueduct 1 along its length is not a through structure, but has a side wall with an end face.

[0044] In addition, it should be noted that the first drive device 2 and the second drive device 5 of this slurry conveying device 1 can be started and operated continuously during the process of conveying slurry, that is, the bottom of the aqueduct 1 can be cleaned continuously along with the slurry conveying. Of course, it is not limited to this. The first drive device 2 and the second drive device 5 can also be started to clean after the aqueduct 1 has been used for a period of time. After cleaning is completed, they can be temporarily turned off and restarted after a period of time. The specific choice depends on the actual needs.

[0045] In this embodiment, preferably, as follows: Figures 3 to 5 As shown, the first transmission mechanism 3 includes a first transmission gear 31, a second transmission gear 32, and an annular chain 33. Along the length of the aqueduct 1, the first transmission gear 31 and the second transmission gear 32 are respectively positioned near both ends of the aqueduct 1. The annular chain 33 surrounds the first transmission gear 31 and the second transmission gear 32 and meshes with both gears. Multiple scraping components 4 are provided, spaced apart on the annular chain 33.

[0046] As can be seen from the structure described above, the first driving device 2 drives the first transmission gear 31 to rotate, which in turn drives the second transmission gear 32 to rotate through the ring chain 33, forming a ring motion mechanism, which in turn drives the scraping component 4 to make a ring motion.

[0047] Furthermore, preferably, the first driving device 2 is a motor.

[0048] Furthermore, preferably, along the length of the aqueduct 1, the second drive device 5 and the cleaning brush 6 are disposed on the outer side of the same end of the first transmission mechanism 3.

[0049] It should be noted that the structure of the first transmission mechanism 3 is not limited to the above, and can be designed according to actual needs. For example, a belt drive structure can also be used.

[0050] In this embodiment, preferably, the slurry conveying device 1 further includes a first support member and a second support member (not shown in the figure); wherein, the first support member and the second support member are both fixed on the aqueduct 1, and the first transmission gear 31 is rotatably connected to the first support member, and the second transmission gear 32 is rotatably connected to the second support member.

[0051] As can be seen from the structure described above, the first support member plays the role of stabilizing the first transmission gear 31, making the first transmission gear 31 more stable during rotation; the second support member plays the role of stabilizing the second transmission gear 32, making the second transmission gear 32 more stable during rotation.

[0052] It should be noted that the first support component may not be required, and the first transmission gear 31 may be directly installed on the inner wall of the aqueduct 1. The specific design depends on the actual needs. Similarly, the second support component may not be required, and the second transmission gear 32 may be directly installed on the inner wall of the aqueduct 1. The specific design depends on the actual needs.

[0053] In this embodiment, preferably, the slurry conveying device 1 further includes a third support member (not shown in the figure), and the fixed end of the first driving device 2 is fixed to the third support member.

[0054] As can be seen from the structure described above, the third support member plays the role of stabilizing and supporting the first drive device 2, and preferably, the third support member is located outside the aqueduct 1, but of course, it is not limited to this.

[0055] Furthermore, preferably, the first driving device 2 and the third supporting member can be connected by bolts for detachment. Of course, this is not the only option; the connection method can be designed according to actual needs.

[0056] In this embodiment, preferably, as follows: Figure 3 As shown, the slurry conveying device 1 also includes a recycling tank 7, which is located near the cleaning brush 6 and is used to receive the carbide slag cleaned up by the scraping member 4.

[0057] As can be seen from the structure described above, the recycling tank 7 serves to recycle calcium carbide slag and prevent the calcium carbide slag that has been brushed off from settling and adhering again.

[0058] It should be noted that: this recycling pool 7 may not be required. Instead, other containers may be used to receive the carbide slag below the sewage outlet, or the cleaned carbide slag may be directly discharged into the conveying system, etc.

[0059] In this embodiment, preferably, as follows: Figure 4 As shown, a serration 41 is formed on one side of the scraping component 4 near the inner wall of the aqueduct 1. That is, serrations 41 are provided on the bottom and side of the scraping component 4. The serrations 41 can effectively scrape away the carbide slag remaining on the bottom and side walls of the aqueduct 1, thereby improving the cleaning effect of the aqueduct 1.

[0060] It should be noted that: the structure is not limited to the one with the serration 41 set on the side of the scraping component 4 near the inner wall of the aqueduct 1. Alternatively, the serration 41 may not be set on the scraping component 4. Instead, the side of the scraping component 4 near the inner wall of the aqueduct 1 may be set into a U-shaped structure along the thickness direction of the scraping component 4. This can also effectively scrape away the residual carbide slag on the bottom and side walls of the aqueduct 1.

[0061] In this embodiment, preferably, as follows: Figure 3 and Figure 4 As shown, the scraping component 4 is a plate-shaped structure perpendicular to the length direction of the aqueduct 1.

[0062] As can be seen from the structure described above, the scraping component 4 adopts a U-shaped scraper structure, which can scrape and clean the bottom wall and side wall of the aqueduct 1. Moreover, the plate-shaped scraping component 4 has a certain strength, is not easily damaged, and has a longer service life. In addition, the plate-shaped scraping component 4 has a simple structure and is easy to process and manufacture.

[0063] Further, preferably, such as Figures 1 to 4 As shown, the cross-section of the aqueduct 1 along its length is U-shaped. More preferably, the plate-shaped scraping member 4 is a semi-circle adapted to the aqueduct 1. However, this is not the only possibility; the shape of the plate-shaped scraping member 4 changes according to the shape of the aqueduct 1. Furthermore, it should be noted that since the aqueduct 1 is a U-shaped channel, and one end of the aqueduct 1 along its length, for example… Figure 3 The left end of the aqueduct 1 is an open structure, meaning that the top of this end of the aqueduct 1 is open, serving as the feed inlet 11; furthermore, preferably, the bottom of the other end of the aqueduct 1 along its length is provided with a discharge outlet 12. Of course, the structure of the aqueduct 1 is not limited to the above and can be designed according to actual needs.

[0064] Furthermore, preferably, a support base 8 is also provided at the bottom of the aqueduct 1 to support the aqueduct 1. Of course, it is not limited to this.

[0065] It should be noted that the structure of scraping component 4 is not limited to the above, and can be designed according to actual needs. For example, scraping component 4 can also be a block.

[0066] In this embodiment, preferably, the slurry conveying device 1 further includes a clamping member (not shown in the figure), and the clamping member is clamped on the annular chain 33, and the scraping member 4 is connected to the clamping member.

[0067] As can be seen from the structure described above, the scraping component 4 is firmly fixed to the ring chain 33 by the clamping component, making the scraping component 4 more stable during movement.

[0068] In this embodiment, preferably, the clamping component includes a first clamping plate, a second clamping plate, a first locking bolt, and a second locking bolt (not shown in the figure); wherein the first clamping plate and the second clamping plate are respectively clamped on opposite sides of the annular chain 33, and the first clamping plate and the second clamping plate are fixed together by the first locking bolt located on the upper part of the annular chain 33 and the second locking bolt located on the lower part of the annular chain 33.

[0069] As can be seen from the structure described above, the two clamping plates are locked together with the annular chain 33 by locking bolts located above and below the annular chain 33, and the first locking bolt at the top also serves as a limit, making the connection between the two clamping plates and the annular chain 33 more stable and secure.

[0070] It should be noted that the structure of the clamping component is not limited to the above; it can also be a U-shaped clamp with a certain degree of elasticity, depending on the actual needs.

[0071] In this embodiment, preferably, the scraping component 4 and the clamping component are detachably connected by bolts (not shown in the figure), and preferably, the scraping component 4 is installed between two clamping plates, and finally fixed together with the clamping plates by bolts, making the overall structure more stable and stronger.

[0072] In this embodiment, preferably, the slurry conveying device 1 further includes a fourth support member (not shown in the figure), and the fixed end of the second driving device 5 is fixed to the fourth support member.

[0073] As can be seen from the structure described above, the fourth support member plays the role of stabilizing and supporting the second drive device 5, and preferably, the fourth support member is disposed outside the aqueduct 1, but of course, it is not limited to this.

[0074] Furthermore, preferably, the second driving device 5 and the fourth support member can be connected by bolts for detachment. Of course, this is not the only option; the connection method can be designed according to actual needs.

[0075] In this embodiment, the second driving device 5 is preferably a motor. Of course, it is not limited to this and can be selected according to actual needs.

[0076] In this embodiment, preferably, as follows: Figure 3As shown, there are multiple scraping components 4, which are arranged sequentially and at intervals along the annular chain 33. Using multiple scraping components 4 improves the cleaning effect on the aqueduct 1. Of course, it is not limited to this; the number of scraping components 4 can also be one, depending on the actual needs of the design.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
