[0001] The utility model relates to the technical field of municipal cleaning, and particularly relates to a device for cleaning sewer sludge. Background Art
[0002] The sewer system is used to collect and discharge domestic wastewater generated in cities and industrial wastewater generated in industrial production. (Urban rainfall is now also planned as urban wastewater). The biggest problem brought by urban rainfall is that it enters the pipeline system together with soil, causing silt to accumulate in the pipeline and affecting the drainage efficiency. In some places with large silt accumulation, a pipeline dredging machine can be directly used for dredging. However, there are some small places where the lateral operation space is limited, making it difficult to use long rod tools. Especially in some sewer areas within 300 mm, although there is not much silt, it is still difficult to clean without suitable tools.
[0003] Based on this, it is necessary to research a device for cleaning sewer sludge. Content of the Utility Model
[0004] In view of this, the purpose of the utility model is to provide a device for cleaning sewer sludge, which can effectively solve the problem that it is difficult to clean with existing tools due to limited space in narrow sewers.

Detailed Embodiment
[0028] The following further describes the present utility model in detail in conjunction with the drawings and specific embodiments:
[0029] This embodiment aims to provide a sewer silt cleaning device, which is mainly used for cleaning the silt in narrow spaces of sewers, aiming at the problem that it is difficult to clean the narrow sewers due to limited space with existing tools.
[0030] A sewer silt cleaning device, as Figure 1 and Figure 2 , includes a collection bin 1, a front shovel bucket 2, a rear filter plate 3, a counterweight support 4, a lifting rod 5 and a handle 6; as Figure 3, the collection bin 1 includes a bottom plate and two side plates vertically arranged on the left and right sides. The bottom plate and the two side plates are integrally formed or can be spliced. The tops of the left and right side plates of the collection bin 1 are both bent inward to form upper connecting parts 108; the top plate 102 is detachably connected to the upper end faces of the two upper connecting parts 108 by screws, enclosing a collection cavity 101 with a front opening and a rear opening.
[0031] In this application, the front refers to Figure 2 the right side in Figure 2 the left side in
[0032] The front shovel bucket 2 is of a trapezoidal structure and is detachably connected to the front end face of the collection bin 1. The front end face of the front shovel bucket 2 is inclined downward to form a mud shoveling slope surface 201. The front shovel bucket 2 is located at the lower part of the front end face of the collection bin 1, so that an inlet for sewage 103 is reserved at the upper part of the front end face of the collection cavity 101. The inlet for sewage 103 is located at the top of the mud shoveling slope surface 201. The mud shoveling slope surface 201 is mainly used to guide the oncoming water flow, so that the water flow climbs along the mud shoveling slope surface 201 and enters the collection cavity 101 through the inlet for sewage 103.
[0033] As Figure 2 , there is a rear opening silt cavity 202 in the front shovel bucket 2; a rabbet 106 extending horizontally outward is arranged at the opening of the front end face of the collection cavity 101, and the outside is the direction away from the collection cavity 101. The silt cavity 202 is sleeved on the rabbet 106 through the opening at the rear end face. Corresponding threaded holes are provided on the rabbet 106 and the silt cavity 202 and are detachably connected by screws, so that the front shovel bucket 2 can be removed; the silt cavity 202 can increase the silt storage space of the device and improve the single - time silt cleaning amount.
[0034] A first water filter port 104 communicating with the outside is opened at the rear end face of the collection cavity 101. Specifically, the rear ends of the left and right side walls of the collection bin 1 are both bent inward to form rear connecting parts 107, and the first water filter port 104 is the area between the two rear connecting parts 107; the rear filter plate 3 is detachably connected to the first water filter port 104 on the rear end faces of the two rear connecting parts 107 by screws. The rear filter plate 3 is detachably installed on the rear end face of the collection bin 1 and blocks the first water filter port 104. Specifically, the rear filter plate 3 is detachably connected to the rear end faces of the two rear connecting parts 107 by screws. When discharging the silt in the device, the rear filter plate 3 or the top plate 102 can be removed, and if necessary, the front shovel bucket 2 can also be removed.
[0035] The counterweight support 4 is fixed to the lower end face of the collection bin 1 by screws, as Figure 2, the front part of the bottom plate of the collection bin 1 is bent forward and downward in an arc shape, which can not only facilitate the sliding of the silt into the silt chamber 202, but also make the lower end surface of the counterweight support 4 and the lower end surface of the front shovel 2 in the same plane, ensuring that the bottom of the mud shoveling slope 201 is in contact with the bottom of the sewer; there are counterweight blocks in the counterweight support 4, which can play a role in stable support and prevent displacement due to water flow scouring.
[0036] Furthermore, the counterweight support 4 is an inverted triangular structure extending in the front-back direction; there are two groups of counterweight supports 4, which are symmetrically fixed on the left and right sides of the lower end surface of the collection bin 1 respectively. The counterweight support 4 does not contact the bottom surface of the sewer, which can avoid the adhesion and adsorption effect with the bottom surface of the sewer due to cement, so as to facilitate the removal of the device.
[0037] Furthermore, a second water filter port 105 communicating with the outside is opened at the bottom of the collection chamber 101, and a lower filter plate 8 is arranged on the second water filter port 105. The lower filter plate 8 is located between the two counterweight supports 4 to improve the water filtering efficiency.
[0038] The lifting rod 5 is vertically fixed at the top of the collection bin 1, and a handle 6 is fixed at the top of the lifting rod 5. The lifting rod 5 and the handle 6 are mainly used to facilitate the deployment and placement of the device at the bottom of the sewer.
[0039] Furthermore, as Figure 2 , in order to prevent the lower end surface of the front shovel 2 from forming an adsorption effect with the bottom of the sewer, the middle area of the lower end surface of the front shovel 2 is recessed upward and there is a gap between it and the edge area of the lower end surface. The lower end surface of the counterweight support 4 and the edge area of the lower end surface of the front shovel 2 are in the same plane.
[0040] Furthermore, an interception grid 7 is arranged at the connection between the collection chamber 101 and the silt chamber 202. The interception grid 7 is mainly used to intercept garbage such as branches and fallen leaves carried in the water flow. The water flow directly entering the collection chamber 101 through the sewage inlet 103 first filters out the water through the rear filter plate 3, and then the garbage and silt remaining in the collection chamber 101 are filtered through the interception grid 7, so that the garbage is intercepted in the collection chamber 101, and the silt can pass through the interception grid 7 and enter the silt chamber 202, thus realizing the separation of garbage and silt for subsequent classification treatment.
