[0002] In the sewage treatment process, when the sewage is treated with a treatment agent or biological treatment, the impurities in the sewage will be flocculated and precipitated. After the supernatant is discharged, in order to ensure that the remaining sewage is completely discharged, the remaining sewage containing impurities will be further squeezed or centrifuged. At this time, the clear water is precipitated and the impurities are squeezed into mud cakes.

[0003] At present, the treatment method for residual sludge is usually to adopt more environmentally friendly harmless treatment and then recycling. Before recycling, in order to facilitate post-processing, the mud cake needs to be crushed accordingly. However, during the crushing process of the general mud cake crushing device, since part of the mud cake is in block shape, it is easy for the mud cake to cross the crushing structure and be unable to fall when it is put into the crushing device, resulting in reduced processing efficiency and mud cake accumulation. Although it can be solved by manual knocking, frequent manual intervention is not only labor-intensive, but also easy to cause the knocking tool to slip out of hand and cause accidents.

DETAILED DESCRIPTION

[0022] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0023] Example 1: Figure 1-4 As shown, a mud cake crushing device for sewage treatment includes a housing 1, a crusher 11, a transmission assembly and a control panel. The crusher 11 is arranged on the upper side of the housing 1, the transmission assembly is arranged on the outer side of the housing 1 and is connected to the crusher 11 in a transmission manner, and the housing 1 is also provided with an auxiliary mechanism matching the crushing mechanism;

[0024] The auxiliary mechanism includes a driven component and a pushing component, the driven component is in transmission connection with the transmission component, and the pushing component is arranged on the upper side of the housing 1 and connected to the driven component;

[0025] The pushing assembly includes an L-shaped connecting rod 2, a vertical connecting rod 21 and an extrusion plate 22. A support frame 23 is provided at the upper opening of the outer shell 1. One end of the L-shaped connecting rod 2 is connected to the driven assembly and extends upward to the opening of the outer shell 1. There are several vertical connecting rods 21 and they are all slidably connected to the support frame 23. Several vertical connecting rods 21 are connected to the L-shaped connecting rod 2. The extrusion plate 22 is connected to the other ends of several vertical connecting rods 21 and matches the position of the crusher 11.

[0026] When crushing the mud cake, the mud cake is thrown into the opening on the upper side of the shell 1. The opening of the shell 1 is in a funnel structure and is provided with a guide plate corresponding to the crusher 11, so that the mud cake can accurately slide into the gap between the two crushers 11 for crushing. In the crushing process, some mud cakes are larger in size and easily cross the gap between the two crushers 11 and span the upper side of the two crushers 11. At this time, it is easy for mud cake to be retained or more mud cake to accumulate, resulting in reduced crushing efficiency. Therefore, in the process of the transmission component driving the crusher 11 to crush, the driven component will also be driven synchronously, so that the driven component drives the L-shaped connecting rod 2 to move up and down, thereby driving the extrusion plate 22 to push toward the crusher 11 through the vertical connecting rod 21 connected to the L-shaped connecting rod 2, so that the mud cake on the upper side of the crusher 11 can be actively pushed toward the crusher 11, so as to ensure that the mud cake can be effectively crushed by the crusher 11, avoid material accumulation and improve processing efficiency.

[0027] The transmission assembly includes a motor, two transmission gears 3 and two transmission shafts 31. The two transmission gears 3 are rotatably connected to the outer shell 1 and are externally meshed with each other. The two transmission shafts 31 are concentrically connected to the two transmission gears 3 and are rotatably arranged in the outer shell 1. The motor is connected to the outer shell 1 and is transmission-connected to one of the transmission gears 3 through the output shaft. The crusher 11 is connected to the transmission shaft 31.

[0028] When the motor is started, it will drive the transmission gear 3 connected to it to rotate through its output shaft, so that the two mutually meshing transmission gears 3 will rotate synchronously, and the two transmission gears 3 will synchronously drive the two transmission shafts 31 to rotate, that is, the two crushers 11 will run. Since the two transmission gears 3 are externally meshed, the running directions of the two crushers 11 are relative, which can effectively crush the mud cake.

[0029] The driven component includes an eccentric shaft 4 and a connecting frame 41. There are two eccentric shafts 4, which are respectively arranged on two transmission gears 3. The eccentric shaft 4 is eccentrically arranged with the transmission gear 3 and the two eccentric shafts 4 are arranged at the same horizontal height relative to the rotation direction. The connecting frame 41 is connected to the outer shell 1 for sliding up and down through a guide rail. The middle opening of the connecting frame 41 is connected to a matching slide groove 42 for sliding connection with the eccentric shaft 4, and one end of the L-shaped connecting rod 2 is connected and matched with the upper end of the connecting frame 41.

[0030] When the transmission gear 3 is running, the eccentric shaft 4 connected to the transmission gear 3 will also move synchronously around the center of the transmission gear 3. At this time, the movement of the eccentric shaft 4 will push the connecting frame 41. Since the connecting frame 41 is connected to the outer shell 1 by sliding up and down through the guide rail, the connecting frame 41 can only be pushed up and down, thereby realizing the up and down reciprocating action on the pushing component.

[0031] Example 2: Figure 1-4As shown, based on the further improvement of Example 1, a screening mechanism is further provided on the lower side of the crusher 11 in the outer shell 1, and the screening mechanism includes a screening frame 5, a slide and a transmission device. The slide is slidably arranged in the outer shell 1, the screening frame 5 is elastically slidably arranged on the slide up and down, and the transmission device is arranged between the driven component and the slide.

[0032] The slide seat includes a support frame 52 and an outer rack 53. The outer shell 1 is provided with an open slot 54. The outer rack 53 is connected to the support frame 52 near the transmission component and extends out of the open slot 54. The transmission device includes a vertical rack 55 and a transmission gear 56. The vertical rack 55 is connected to the lower end of the connecting frame 41. The transmission gear 56 is composed of two concentrically connected gears. The two gears of the transmission gear 56 are respectively meshed and connected with the outer rack 53 and the vertical rack 55.

[0033] A vibrator is also provided on the lower side of the screening frame 5, and the vibrator includes a guide wheel 6 and a horizontal bar 61. The horizontal bar 61 is fixed in the outer shell 1 and is parallel to the moving direction of the support frame 52. A plurality of bosses 62 are evenly provided on the upper end of the horizontal bar 61. The number of guide wheels 6 is several and is evenly provided at the lower end of the screening frame 5 and corresponds to the position of the horizontal bar 61.

[0034] In order to further improve the crushing effect, after the mud cake is crushed by the crusher 11, it will fall into the screening frame 5. In order to ensure the effectiveness of guiding the mud cake, guide plates are provided on the upper and lower sides of the crusher 11 in the housing 1. As the driven component runs, the vertical rack 55 in the transmission will move up and down synchronously with the connecting frame 41, and the vertical rack 55 will output the rotational force to the outer rack 53 through the transmission gear 56. At this time, the outer rack 53 is driven by the transmission gear 56 to swing back and forth. In the embodiment, the guide wheel 6 at the lower end of the screening frame 5 will move along the horizontal bar 61, and the guide wheel 6 will be blocked by the boss 62 and produce an upward lifting effect, wherein the screening frame 5 and the slide seat are elastically slidably connected up and down. In this embodiment, a spring or a spring plate connection can be used to keep the screening frame 5 moving downward in the initial state, so that the screening frame 5 can generate radial vibration during the movement along the horizontal bar 61, so that vibration can also be generated during the swinging process of the screening frame 5, so as to effectively screen the crushed mud cake residue in the screening frame 5.

[0035] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
