[0002] A sludge crusher is a device used for the mechanical crushing of sludge. By crushing, the volume of sludge can be reduced, which is beneficial for subsequent transportation and treatment. Rotary crushers are a common type of sludge crusher, which can use the relative motion between rotating rollers to tear and crush the sludge.

This sludge crusher has advantages such as compact structure, simple operation, convenient maintenance, and high working efficiency, achieving uniform crushing of highly viscous sludge and meeting the crushing needs of municipal sludge.

[0004] Existing technologies often have the following drawbacks: after sludge is crushed by a sludge crusher, some sludge remains in relatively large pieces, which cannot meet the user's needs for sludge crushing and thus reduces the performance of the sludge crusher.

[0005] Therefore, this utility model provides a sludge crusher. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies where the crushed sludge does not meet the crushing requirements, and to propose a sludge crusher.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a sludge crusher, comprising a main support, a crushing box fixedly installed on the inner side of the main support, an active roller and a driven roller rotatably installed inside the crushing box, a screening device provided on the inner side of the main support, the screening device comprising four sleeves fixedly connected to the inner side of the main support, a sliding rod slidably installed on the inner side of each of the four sleeves, a screen plate fixedly connected to one end of each of the four sliding rods that is close to each other, and a plurality of screen holes evenly opened on the surface of the screen plate.

[0008] The effect achieved by the above components is that the shredded sludge falls onto the screen plate for screening, and during the screening process, small sludge particles pass through the screen holes and fall onto the guide plate for guidance.

[0009] Preferably, a spring is fitted on the outside of the sleeve and the slide rod, and the two ends of the spring are fixedly connected to the main support and the sieve plate, respectively.

[0010] The effect achieved by the above components is that by setting springs, the horizontal shaking effect of the screen plate is improved, which further improves the screening efficiency during the use of the screen plate.

[0011] Preferably, a guide plate is fixedly connected to the inner side of the main support.

[0012] The effect achieved by the above components is that small sludge particles will pass through the screen holes and fall onto the guide plate for guidance during the screening process.

[0013] Preferably, a connecting frame is fixedly connected to the surface of the sieve plate, and a diamond-shaped block is fixedly connected to the side wall of the driven roller.

[0014] The effect achieved by the above components is that the rhombus block will move relative to the connecting frame, and the inclined surface of the rhombus block will squeeze and push the connecting frame to move.

[0016] The effect achieved by the above components is that there will be relative movement between the regulating hole and the screen hole, and the gap formed by the overlap between the regulating hole and the screen hole is the gap through which the material flows out. By adjusting the size of the overlapping gap, it is convenient to screen sludge of different particle sizes.

[0017] Preferably, both the sieve holes and the adjusting holes are rhomboid in shape.

[0018] The effect achieved by the above components is that by setting the adjustment hole and the sieve hole to be rhomboid, the gap after the two overlaps is still rhomboid, which facilitates the proportional scaling of the gap during the adjustment process.

A drive rod is internally threaded into the installation block, and the drive rod and the positioning block are internally rotatably connected.

[0020] The effect achieved by the above components is that rotating the drive rod will cause the mounting block and the slide plate to move inside the slide groove.

[0021] In summary:

[0022] 1. In this utility model, when the inclined surface of the rhomboid block is pressed through the connecting frame, the screen plate will be reset by the spring force. By setting the spring, the horizontal shaking effect of the screen plate is improved, which further improves the screening efficiency during the use of the screen plate. By setting the screening device, the screening of processed sludge materials is facilitated, and sludge that cannot meet the crushing requirements can be screened twice or multiple times, which effectively improves the crushing efficiency of sludge.

[0030] Reference Figure 1 As shown, this utility model provides a technical solution: a sludge crusher, including a main support 1, a crushing box 2 fixedly installed on the inner side of the main support 1, an active roller 3 and a driven roller 4 rotatably installed inside the crushing box 2, a screening device 5 provided on the inner side of the main support 1, and an adjustment device 6 provided on the surface of the screen plate 51.

[0031] The following section will describe in detail the specific settings and functions of the screening device 5 and the regulating device 6.

[0032] Reference Figures 1-5 As shown in this embodiment, the screening device 5 includes four sleeves 55 fixedly connected to the inner side of the main support 1. Each of the four sleeves 55 has a sliding rod 56 slidably installed on its inner side. A screen plate 51 is fixedly connected to one end of each sliding rod 56 that is close to the other. The surface of the screen plate 51 is evenly provided with a plurality of screen holes 58. The shredded sludge falls onto the screen plate 51 for screening. During the screening process, small sludge particles pass through the screen holes 58 and fall onto the guide plate 52 for guidance.

[0033] Springs 57 are fitted onto the outer sides of sleeve 55 and slide rod 56, with both ends of spring 57 fixedly connected to the main support 1 and screen plate 51, respectively. By installing spring 57, the horizontal shaking effect of screen plate 51 is improved, further enhancing the screening efficiency during use. A guide plate 52 is fixedly connected to the inner side of the main support 1. During screening, small sludge particles pass through the screen holes 58 and fall onto the guide plate 52 for guidance. A connecting frame 53 is fixedly connected to the surface of screen plate 51, and a rhomboid block 54 is fixedly connected to the side wall of driven roller 4. The rhomboid block 54 moves relative to the connecting frame 53, and the inclined surface of the rhomboid block 54 pushes and compresses the connecting frame 53 to move.

[0034] Reference Figures 1-5 As shown, specifically, the adjusting device 6 includes two grooves 65 formed on the surface of the screen plate 51. A sliding plate 61 is slidably connected to the inner walls of the two grooves 65. The surface of the sliding plate 61 is evenly provided with several adjusting holes 66. Relative movement occurs between the adjusting holes 66 and the screen holes 58. The gap formed by the overlap between the adjusting holes 66 and the screen holes 58 is the material outflow gap. Adjusting the size of the overlapping gap facilitates the screening of sludge of different particle sizes. Both the screen holes 58 and the adjusting holes 66 are rhomboid in shape. By setting the adjusting holes 66 and the screen holes 58 to be rhomboid, the overlapping gap remains rhomboid, facilitating proportional scaling of the gap during adjustment. A positioning block 62 is fixedly installed on the surface of the screen plate 51, and an mounting block 63 is fixedly installed on the surface of the sliding plate 61. A drive rod 64 is threadedly connected inside the mounting block 63, and the drive rod 64 is rotatably connected to the positioning block 62. Rotating the drive rod 64 will cause the mounting block 63 and the slide plate 61 to move inside the slide groove 65.

[0035] Working principle: When sludge needs to be crushed, the sludge is placed inside the crushing box 2. The relative movement between the driving roller 3 and the driven roller 4 shreds and breaks down the sludge. The shredded sludge falls onto the screen plate 51 for screening. During screening, small sludge particles pass through the screen holes 58 and fall onto the guide plate 52 for guidance, while larger sludge particles fall directly down along the screen plate 51, thus achieving the screening of sludge particles of different sizes. The larger sludge particles are collected for secondary screening until they meet the user's needs. During the rotation of the driven roller 4, the diamond-shaped block 54 interacts with the connecting frame 5. Relative motion occurs between the three components. The inclined surface of the rhombus block 54 will squeeze and push the connecting frame 53 to move. The sliding rod 56 slides inside the sleeve 55, which restricts the movement direction of the screen plate 51. When the inclined surface of the rhombus block 54 squeezes through the connecting frame 53, the screen plate 51 will be reset by the elastic force of the spring 57. By setting the spring 57, the horizontal shaking effect of the screen plate 51 is improved, which further improves the screening efficiency during the use of the screen plate 51. By setting the screening device 5, the screening of processed sludge materials is facilitated, and sludge that cannot meet the crushing requirements can be screened twice or multiple times, which effectively improves the crushing efficiency of sludge.

[0036] When the size of the sieve aperture needs to be adjusted, the drive rod 64 can be rotated. The drive rod 64 will drive the mounting block 63 and the sliding plate 61 to move inside the chute 65. The sliding plate 61 inside the chute 65 serves as a guide. At this time, there will be relative movement between the adjustment hole 66 and the screen hole 58. The aperture formed by the overlap between the adjustment hole 66 and the screen hole 58 is the aperture through which the material flows out. By adjusting the size of the overlap aperture, it is convenient to screen sludge of different particle sizes, further meeting the user's screening needs after sludge crushing. By setting the adjustment hole 66 and the screen hole 58 to be rhomboid, the aperture after their overlap is still rhomboid, which facilitates the proportional scaling of the aperture during the adjustment process. By setting the adjustment device 6, it is convenient to flexibly adjust the size of the sieve aperture of the screen plate 51, further improving the screening efficiency of the sludge after processing.

[0037] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
