Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of dangerous waste transfer equipment, especially to a discharging transfer compartment of a ditching residual mud treatment station. BACKGROUND

[0002] The city drainage system needs to be dredged periodically or irregularly. Since the early drainage system is mostly surface ditch, the dredged material of the drainage system is called ditching residual mud. The ditching residual mud contains complex components, which usually needs to be treated by a sludge treatment station before being discharged or recycled. The current sludge treatment station can separate or remove organic matter, inorganic matter and water in the ditching residual mud through a series of physical, chemical or biological methods, so as to reduce the volume of sludge, stabilize the properties of sludge and reduce environmental pollution. Due to the limited processing speed of the treatment station and the unstable incoming materials of the ditching residual mud, the discharge of the sludge treatment station usually needs to be stacked to reach the loading capacity of the transport vehicle before being transferred. This process increases the space and labor cost of the sludge treatment station.

[0003] To solve this technical problem, the industry has developed a special sludge transport compartment. For example, the Chinese patent application with the application publication number CN108688545A discloses a sludge transport compartment. The transport compartment has a box with a sealed cavity. The top of the box has a sludge inlet and a power input port which are in communication with the sealed cavity and arranged side by side. The box has a discharge port in communication with the sealed cavity on the side wall and a rear door assembly which seals the discharge port. The rear door assembly is rotatably arranged and can be rotated upwardly to open relative to the bottom of the box. The bottom of the rear door assembly is connected to the bottom of the box through a locking mechanism. The screw pushing mechanism includes a screw pushing rod which is rotatably arranged in the upper space of the sealed cavity and across the sludge inlet. The power end of the screw pushing rod is connected to the power transmission member, and the power transmission member has a connection part connected to the power source, which extends into the power input port. Through the transport compartment, the discharge of the sludge treatment station can be concentrated and transported at one time, avoiding the space cost and labor cost caused by stacking. However, in actual use, we found that the gate assembly and screw pushing mechanism of the transport compartment need to be connected to the external power input, which makes the transport compartment need to be connected to the power source of the transport vehicle during use. This not only increases the difficulty of using the equipment, but also restricts the use frequency of the transport vehicle, i.e. only one vehicle corresponds to one compartment for use, increasing the use cost of the equipment.

[0025] The utility model embodiment provides a kind of ditching residual mud processing station discharging transfer compartment (referred to as the present transfer compartment), and the present transfer compartment has the following structural features:

[0026] As Figs. 1 to 4As shown, the transport compartment includes a box 02 and a bracket 01, the top of the box 02 is provided with a feeding port 021, one side of the box is provided with a discharge port 022, the top outer wall of the discharge port 022 is hingedly connected with a movable closing plate 023, the outer side wall of the movable closing plate 023 is provided with a first hydraulic push rod 024, the fixed end of the first hydraulic push rod 024 is hingedly connected with the top outer wall of the discharge port 022, and the movable end of the first hydraulic push rod 024 is hingedly connected with the movable closing plate 023; the side opposite to the discharge port 022 of the box 02 is provided with a fixed closing plate 025, the box 02 is enclosed into a storage cavity 026 through the fixed closing plate 025 and the movable closing plate 023, and a hydraulic scraper 05 is arranged in the storage cavity 026; the hydraulic scraper 05 includes a second hydraulic rod 051 arranged on the outer side wall of the feeding port 021 and a scraper rod 052 fixedly connected with the movable end of the second hydraulic rod 051, the stroke direction of the movable end of the second hydraulic rod 051 is the length direction of the box 02, the side wall of the box 02 is provided with a scraper rod sliding through slot 027 in the length direction, and one end of the scraper rod 052 is fixedly connected with the movable end of the second hydraulic rod 051 through the scraper rod sliding through slot 027; the end close to the fixed closing plate of the box 02 is provided with a power station accommodating cavity 028, a hydraulic power station (not shown) is placed in the power station accommodating cavity 028, the hydraulic power station can be selected or customized according to pressure requirements, and the hydraulic power station is connected with the first hydraulic push rod 024 and the second hydraulic rod 051 of the hydraulic scraper 05 through a hydraulic pipeline; the bracket is fixedly connected with the bottom of the box. In the use process of the transport compartment, the transport compartment is pushed to the discharge end of the processing station directly below, the discharge of the processing station is received through the feeding port of the box, the discharge falls into the storage cavity from the feeding port, and the storage cavity is continuously filled with the discharge of the processing station, at this time, the second hydraulic rod is driven by the hydraulic power station to scrape the material pile in the storage cavity back and forth, so that the discharge is evenly distributed in the storage cavity. At the same time, when the transport compartment enters the processing station to load the discharged material such as treated silt particles, the movable closing plate is in a closed state under the pushing of the first hydraulic push rod, when the transport compartment is transported to the discharge point by the towing vehicle, the movable closing plate is pulled up by the first hydraulic push rod controlled by the hydraulic power station, so that the discharge port is opened, and the towing vehicle S cooperates with the lifting bracket to tilt the box, so that the silt particles are quickly poured out of the discharge port.
