DETAILED DESCRIPTION

[0034] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0035] ​​​​In order to make the person skilled in the art better understand the scheme of the present application, the technical scheme in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor should belong to the protection scope of the present application.

[0036] As shown in Figures 1-2 The present application provides a sludge crusher, which comprises a frame body 1 and a crushing mechanism 2 fixedly arranged at the upper end of the frame body 1, and the crushing mechanism 2 is used for efficiently and finely crushing the sludge;

[0037] The crushing mechanism 2 comprises a crushing box 20 fixedly arranged at the upper end of the frame body 1, and the crushing box 20 provides a space for the sludge to be crushed, and the crushing box 20 is hollowly arranged to facilitate the introduction and smooth discharge of the sludge, thereby preventing clogging, and two groups of crushing rollers 23 are rotatably arranged in the crushing box 20, and the crushing rollers 23 are suitable for crushing the base material;

[0038] Meanwhile, a first motor 22 is fixedly arranged at one side of the crushing box 20, and the output end of the first motor 22 is fixedly installed with one group of crushing rollers 23, and a second motor 21 is fixedly arranged at the other side of the crushing box 20, and the output end of the second motor 21 is fixedly installed with the other group of crushing rollers 23;

[0039] And a crushing knife 24 is fixedly installed on each of the two groups of crushing rollers 23, and the two groups of crushing knives 24 are staggered, so that the two groups of crushing rollers 23 can be driven to move towards each other by the first motor 22 and the second motor 21, and the crushing knives 24 on the crushing rollers 23 can crush the sludge by extrusion, so that the large sludge is crushed to achieve the purpose of crushing the sludge;

[0040] As shown in Figure 1 and Figures 3-4 In order to uniformly feed the sludge, a feeding mechanism 3 is fixedly arranged at the upper end of the crushing box 20, and the feeding mechanism 3 is used for feeding the sludge into the crushing mechanism 2 for crushing treatment;

[0041] The feeding mechanism 3 comprises a feeding hopper 30 fixedly arranged at the upper end of the crushing box 20, and the feeding hopper 30 is conically arranged to facilitate the introduction of the sludge into the crushing mechanism 2, and in order to prevent the sludge from having too high water content, thereby forming a compact block structure, and further causing the sludge to arch and bridge, a feeding assembly 32 is fixedly arranged at the upper end of the feeding hopper 30, and the feeding assembly 32 is used for introducing the sludge into the feeding hopper 30 while reducing the water content, so that the sludge is difficult to coalesce into a block;

[0042] The feed assembly 32 includes a bracket 320 fixedly mounted on the top of the feed hopper 30. A cover 321 is fixedly mounted on the upper end of the bracket 320. The cover 321 is used to prevent sludge from splashing during transportation. Two sets of notches are opened at the upper and lower ends of the cover 321. The notches are used for loading and guiding sludge into the feed port 30.

[0043] Mounting seats 322 are fixedly provided at both ends of the bracket 320, and a rotating shaft 325 is rotatably provided between the mounting seats 322. The rotating shaft 325 passes through the housing 321 and enters the interior thereof.

[0044] At the same time, a spiral blade 324 is fixedly provided on the portion of the rotating shaft 325 located inside the housing 321. The spiral blade 324 is spirally distributed on the rotating shaft 325. A third motor 323 is fixedly provided at one end of the bracket 320. The output end of the third motor 323 is fixedly connected to one end of the rotating shaft 325. Thus, the rotating shaft 325 can be driven by starting the third motor 323 to drive the spiral blade 324 to rotate inside the housing 321. During the rotation, the sludge can be continuously pushed toward the notch at the lower end of the housing 321.

[0045] At the same time, in order to evaporate the water in the sludge while transporting it, a hollow chamber is provided inside the rotating shaft 325, and a rotary joint 326 is rotatably provided in the hollow chamber. For example, patent publication number CN201359161Y discloses a rotary joint with good sealing performance. The other end of the rotary joint 326 is fixedly provided with an external connecting pipe, so that the external heating medium can be introduced into the rotating shaft 325 through the rotary joint 326, thereby reducing the water content therein to varying degrees and preventing the water from agglomerating into lumps due to excessive water.

[0046] Therefore, when the sludge needs to be heated, an external heating medium can be introduced through the rotary joint 326 to heat the internal cavity of the rotating shaft 325. The rotating shaft 325 heats the sludge so that the sludge can be kept sufficiently dry during transportation, thereby further reducing the internal moisture.

[0047] like Figures 3-5 As shown, in order to compact the sludge introduced into the feed hopper 30 and prevent the sludge from forming arches and bridges in the feed hopper 30, a pressing assembly 31 is fixedly provided on both sides of the interior of the feed hopper 30. The pressing assembly 31 is used to compact the sludge, thereby preventing the sludge from being evenly and tightly arranged in the feed hopper and avoiding the formation of arches and bridges.

[0048] The pressing assembly 31 comprises two sets of mounting frames 310 fixedly arranged on both sides of the inside of the feeding hopper 30, and a cylinder 314 is fixedly arranged on the mounting frame 310, and an extension rod (not shown in the figure) is fixedly connected to the output end of the cylinder 314, so that the extension rod can be pushed into the inside of the feeding hopper 30 by starting the cylinder 314;

[0049] And a pressing plate 313 is fixedly arranged on one end of the extension rod, which is used for directly contacting with the sludge, and the pressing plate 313 is arranged along the two sides of the inside of the feeding hopper 30, so that the pressing plate 313 can slide along the inside of the feeding hopper 30 by driving the cylinder 314;

[0050] And the pressing assembly 31 on both sides of the feeding hopper 30 intermittently presses the sludge, so as not to affect the normal work of the crusher, when the sludge needs to be pressed, the cylinder 314 can be started to push the pressing plate 313 vertically downward along the inside of the feeding hopper 30, until the pressing plate 313 can closely adhere to the surface of the sludge, and then the pressing plate 313 can generate pressure to destroy the arch bridge formed by the sludge, so as to further improve the crushing efficiency.

[0051] The above only describes the preferred embodiments of the present application, and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
