Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of wet sludge silo structure, specifically to a bridge breaking device and its wet sludge silo. Background Technology
[0002] As a key piece of equipment in the sludge treatment field, the operation of wet sludge silos mainly relies on the gravity of the sludge itself, causing it to flow automatically to the silo outlet. However, the inherent characteristics of sludge—high viscosity, poor flowability, and strong adhesion—pose significant challenges to the normal operation of the silos. Inside the silo, wet sludge is prone to arching, which frequently causes silo blockages during actual use, preventing the sludge from being discharged normally and severely impacting the efficiency and continuity of sludge treatment.
[0003] To address the aforementioned issues, a bridge-breaking device is typically installed inside the wet sludge silo. For example, CN214932564U discloses a bridge-breaking device for a wet sludge silo, comprising a wet sludge silo and a discharge port on the silo. The wet sludge silo includes a front sidewall and a rear sidewall. The bridge-breaking device includes a bracket fixedly mounted on the front sidewall, a reduction motor mounted on the bracket, and a bridge-breaking shaft connected to the reduction motor. A front end cover is provided on the front sidewall, and the bridge-breaking shaft passes through the front end cover into the interior of the wet sludge silo, with bridge-breaking blades mounted on the shaft. When the reduction motor rotates, it drives the bridge-breaking shaft to rotate, causing the bridge-breaking blades to cut the sludge.
[0004] The aforementioned wet sludge silo arch-breaking device mainly breaks the sludge bridge by rotating the arch-breaking shaft, which drives the arch-breaking shaft blades to cut the sludge. However, during the bridge-breaking process, there is a certain gap between two adjacent arch-breaking shaft blades. The sludge in this gap is not subjected to cutting force, resulting in poor bridge-breaking effect of this wet sludge silo arch-breaking device. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a bridge breaking device and its wet sludge silo, so as to solve the problem that the existing wet sludge silo bridge breaking device has a relatively poor bridge breaking effect.
[0006] To achieve the above objectives, the first aspect of this utility model adopts the following technical solution: a bridge-breaking device, installed inside the discharge port of a wet sludge silo, including a bridge-breaking shaft, and further comprising:
[0007] The first arch-breaking section is connected to the arch-breaking shaft and has a first arch-breaking scraper located outside the arch-breaking shaft and arranged parallel to the arch-breaking shaft.
[0008] The second arch-breaking section is connected to the arch-breaking shaft. It has a second arch-breaking scraper located outside the arch-breaking shaft and arranged parallel to the arch-breaking shaft. The projection lines of the second arch-breaking scraper and the first arch-breaking scraper on the arch-breaking shaft are connected and distributed from one end of the arch-breaking shaft to the other end after being connected.
[0009] The second aspect of this utility model adopts the following technical solution: a wet sludge silo, including the bridge-breaking device described in the first aspect of this utility model.
[0010] Compared with the prior art, the present invention has the following beneficial effects:
[0011] In this solution, the bridging device drives the first and second bridging sections to rotate during the rotation of the bridging shaft. The arrangement of the first and second bridging scrapers allows for a sufficiently long contact position with the inner wall of the outlet of the wet sludge silo, and also generates a squeezing force on the sludge towards the outlet, resulting in a better bridging effect.

Detailed Implementation
[0018] The present invention will be further described in detail below through specific embodiments:
[0019] like Figure 2 and Figure 4As shown in the figure, this utility model embodiment proposes a bridge breaking device, which is installed in the discharge port of a wet sludge silo. It includes a bridge breaking shaft 11, a first bridge breaking part 12, and a second bridge breaking part 13. The first bridge breaking part 12 is connected to the bridge breaking shaft 11 and has a first bridge breaking scraper 121 located outside the bridge breaking shaft 11 and arranged parallel to the bridge breaking shaft 11. The second bridge breaking part 13 is connected to the bridge breaking shaft 11 and has a second bridge breaking scraper 131 located outside the bridge breaking shaft 11 and arranged parallel to the bridge breaking shaft 11. The projection lines of the second bridge breaking scraper 131 and the first bridge breaking scraper 121 projected onto the bridge breaking shaft 11 are connected and distributed from one end of the bridge breaking shaft 11 to the other end.
[0020] In this solution, the bridging device drives the first bridging part 12 and the second bridging part 13 to rotate during the rotation of the bridging shaft 11. The arrangement of the first bridging scraper 121 and the second bridging scraper 131 allows for a sufficiently long contact position with the inner wall of the outlet of the wet sludge silo, and also generates a squeezing force on the sludge towards the outlet, resulting in a better bridging effect.
[0021] In this embodiment, a driver 14 connected to one end of the arch-breaking shaft 11 is also included. The driver 14 can be a motor to provide power for the rotation of the arch-breaking shaft 11 so that the first arch-breaking scraper 121 and the second arch-breaking scraper 131 cooperate to efficiently break the bridge.
[0022] To better understand this solution, further explanation is provided below.
[0023] like Figure 2 and Figure 4 As shown, according to another embodiment of the present invention, the bridge breaking device wherein the first arch breaking part 12 and the second arch breaking part 13 have the same structure and each further includes two support blocks 122, the two support blocks 122 being connected one-to-one between the arch breaking shaft 11 and the two ends of the first arch breaking scraper 121 or the two ends of the second arch breaking scraper 131.
[0024] Specifically, the two support blocks 122 are arranged in a "U" shape with the first arch-breaking scraper 121 or the second arch-breaking scraper 131 so that the first arch-breaking scraper 121 or the second arch-breaking scraper 131 is stably connected to the arch-breaking shaft 11; and the structure formed is simple. The space inside the two support blocks 122 and the first arch-breaking scraper 121 or the second arch-breaking scraper 131 allows the sludge in the outlet of the wet sludge silo to pass through, avoiding the sludge in the outlet of the wet sludge silo from being thrown out of the inlet of the wet sludge silo during rotation.
[0025] When the first arch-breaking scraper 121 and the second arch-breaking scraper 131 rotate with the arch-breaking shaft 11 to make circular motion in the discharge port of the wet sludge silo, they slide in contact with the inner wall of the discharge port to better cut the sludge. When they rotate to the bottom of the discharge port, they generate a downward squeezing force on the sludge so that the sludge can be discharged from the discharge port of the wet sludge silo more effectively.
[0026] To further improve the connection strength between the first arch-breaking scraper 121 or the second arch-breaking scraper 131 and the arch-breaking shaft 11, a plurality of reinforcing blocks 123 (such as...) are connected between the arch-breaking shaft 11 and the first arch-breaking scraper 121 or the second arch-breaking scraper 131, located between the two support blocks 122. Figure 3 and Figure 5 Meanwhile, during the rotation of the arch-breaking shaft 11, the reinforcing block 123 can also disperse the sludge in the discharge port of the wet sludge silo, which is more conducive to bridge breaking.
[0027] The number of the reinforcing blocks 123 can be one, two, or three, and can be adjusted according to actual needs.
[0028] like Figures 2-5 As shown, according to another embodiment of the present invention, the bridge breaking device wherein the first arch breaking part 12 and the second arch breaking part 13 are each at least one and have a plurality of circumferentially distributed on the outside of the arch breaking axis 11.
[0029] The number of the first arch-breaking portion 12 and the second arch-breaking portion 13 will be explained in two different ways below.
[0030] like Figure 2 and Figure 3 The first one is:
[0031] There are two of each of the first arch-breaking parts 12 and the second arch-breaking parts 13. The two first arch-breaking parts 12 and the two second arch-breaking parts 13 are distributed on different sides of the arch-breaking axis 11 and are arranged in the same plane.
[0032] At this point, the bridge-breaking device has sufficient structural strength to efficiently break the bridge.
[0033] like Figure 4 and Figure 5 The second type is:
[0034] There is one first arch-breaking part 12 and one second arch-breaking part 13. The first arch-breaking part 12 and the second arch-breaking part 13 are distributed on different sides of the arch-breaking axis 11 and are arranged in the same plane.
[0035] At this point, compared to the first type, the bridge-breaking device reduces the resistance encountered during bridge breaking and can also break bridges efficiently.
[0036] It should be noted that the number and distribution of the first arch-breaking part 12 and the second arch-breaking part 13 are not limited to the two structures mentioned above.
[0037] like Figure 1-5 As shown, according to another embodiment of the present invention, the wet sludge silo includes a bridging device as described in any of the above embodiments, as well as other existing structures, so that the wet sludge silo in this application has good bridging ability and can transport sludge more efficiently. Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of the present invention without departing from the spirit and scope of the present invention, and all such modifications and substitutions should be covered within the scope of the claims of the present invention.
