Description

Technical Field

[0001] This utility model belongs to the field of building construction, and in particular relates to a mobile and replaceable wastewater and waste residue collection device. Background Technology

[0002] Concrete transport equipment, such as concrete pump trucks, mixer trucks, and concrete mixers, generates wastewater and waste residue during construction. Improper handling can lead to indiscriminate discharge of wastewater and dumping of waste residue, causing environmental damage. Currently, the common practice is to set up treatment ponds at fixed locations, drive the concrete transport equipment to these ponds, and discharge the wastewater and waste residue into them for later treatment. However, the centralized location of these treatment ponds makes it difficult to collect the generated wastewater and waste residue promptly, which is a major reason for the indiscriminate discharge and dumping of wastewater and waste residue at construction sites. Therefore, a device that can conveniently and readily collect wastewater and waste residue is needed to solve this problem. Summary of the Invention

[0003] The problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a mobile and replaceable wastewater and waste residue collection device.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0022] The device in this embodiment includes trolley A1, trolley B17, and trolley C18, wherein trolley A1, trolley B17, and trolley C18 can all move independently. Preferably, each of trolley A1, trolley B17, and trolley C18 is provided with a handle 37 for pushing. Trolley B17 and trolley C18 can be fixed to both sides of trolley A1, or they can be detached from trolley A1 and moved independently. Trolley A1 includes a rectangular frame A2, and a caster A3 is provided at the bottom of the rectangular frame A2; trolley B17 includes a rectangular frame B19, and a caster B20 is provided at the bottom of the rectangular frame B19; trolley C18 includes a rectangular frame C21, and a caster C22 is provided at the bottom of the rectangular frame C21. Preferably, casters A3, B20, and C22 are all swivel casters. The length and width of rectangular frames B19 and C21 are equal to the length and width of rectangular frame A2. Preferably, the height of rectangular frames B19 and C21 is lower than that of rectangular frame A2.

[0023] The specific connection between trolleys B17 and C18 and trolley A1 is as follows: Several threaded holes A14 are provided from top to bottom on the vertical support rods A13 at the four corners of the rectangular frame A2; several threaded holes B28 are provided from top to bottom on the front and rear vertical support rods B27 of the rectangular frame B19; similarly, several threaded holes C30 are provided from top to bottom on the front and rear vertical support rods C29 of the rectangular frame C21. Both threaded holes B28 and C30 correspond to threaded holes A14. A transverse long screw B31 passes through threaded holes B28 and A14 and is threaded to the rectangular frame A2. The long screw B31 is tightened with nut B33, thus connecting trolley B17 to trolley A1. Similarly, a transverse long screw C32 passes through threaded holes C30 and A14 and is threaded to the rectangular frame A2. The long screw C32 is tightened with nut C34, thus connecting trolley C18 to trolley A1. Preferably, both long screws B31 and C32 have a slotted hand-tightening knob 38 at their outer ends.

[0024] A wastewater collection main tank 4 is placed inside a rectangular frame A2. The upper surface of the wastewater collection main tank 4 has an inlet 5. Two parallel U-shaped support frames 6 are fixed upwards on the upper ends of the left and right sides of the rectangular frame A2. The upper parts of the two U-shaped support frames 6 are connected together by two longitudinal support rods 7. A hopper 8 is fixed between the two longitudinal support rods 7, with its lower opening facing the inlet 5. A filter screen 9 is provided in the middle of the hopper 8. The filter screen 9 is used to separate waste residue and wastewater. Wastewater leaks through the filter screen 9 into the inlet 5 below and is collected by the wastewater collection main tank 4, while waste residue remains on the filter screen 9. A slag outlet 10 is provided on the side of the hopper 8 facing the filter screen 9. The slag outlet 10 is inclined downwards and connected to a slag discharge chute 11. A baffle 12 is provided on the inner surface of the slag outlet 10 to block it. The baffle 12 is provided with a handle 36 at the upper end. The baffle 12 is inserted into the U-shaped slot 35. The U-shaped slot 35 is welded above the slag outlet 10. The baffle 12 can slide up and down in the U-shaped slot 35, thereby opening or blocking the slag outlet 10.

[0025] An L-shaped outlet pipe 15 is connected to the lower middle part of the side of the main wastewater collection tank 4, opposite to the slag discharge chute 11. A valve 16 is installed on the L-shaped outlet pipe 15. The L-shaped outlet pipe 15 is used to release water from the main wastewater collection tank 4, and the valve 16 is used to control the release of wastewater. Water can be discharged by gravity, or a water pump can be installed in the main wastewater collection tank 4. The water pump is connected to the L-shaped outlet pipe 15 through a pipe to increase the amount and speed of water discharged.

[0026] A waste collection box 23 is placed inside the trolley B17. The waste collection box 23 has an opening at the top and is located below the slag discharge chute 11. The waste slag that slides down from the slag discharge chute 11 falls into the waste collection box 23.

[0027] A wastewater collection sub-tank 24 is placed inside the trolley C18. A collection hole 25 is provided on the upper surface of the wastewater collection sub-tank 24, located directly below the L-shaped outlet pipe 15. Wastewater flowing from the L-shaped outlet pipe 15 enters the wastewater collection sub-tank 24 through the collection hole 25. An outlet is provided at the bottom of the outer side of the wastewater collection sub-tank 24, and a cover 26 is provided at the outlet. The wastewater in the wastewater collection sub-tank 24 is discharged into a unified treatment tank through the outlet.

[0028] In actual construction, multiple identical trolleys B17 and C18, waste collection box 23, and wastewater collection auxiliary box 24 can be made. First, align trolleys B17 and C18 with trolley A1, aligning threaded holes B28 and C30 with threaded holes A14 on both sides. Then, rotate the long screws B31 and C32 on both sides to screw them into the threaded holes A14 of the vertical support rod A13 of trolley A1. Secure the long screws B31 and C32 with nuts B33 and C34, thus fixing trolleys B17 and C18 to trolley A1. Then, push the device to the concrete transport equipment, such as a concrete pump truck, so that the discharge port of the concrete pump truck is aligned with the discharge hopper 8 to discharge wastewater and waste residue. The wastewater in the discharge hopper 8 passes through the filter screen 9 and enters the wastewater collection main box 4 below. The waste residue remains on the filter screen 9. When there is a lot of waste residue, pull open the baffle 12, and manually push the waste residue on the filter screen 9 to the slag outlet 10 with a tool, and then enter the waste residue collection box 23 through the slag discharge chute 11. When the entire device collects a lot of wastewater or waste residue, or when the mass is large, the trolley B17 or trolley C18 can be replaced at any time. Turn the long screw B31 or long screw C32 to detach the trolley B17 or trolley C18 from the trolley A1, and then replace it with a new trolley B17 or trolley C18. Workers can push the dismantled trolleys B17 or C18 to the centralized treatment pool, where they can directly pour the wastewater or waste residue into the corresponding treatment pool. After emptying the wastewater collection tank 24 or the waste residue collection tank 23, the trolley can be fixed back to trolley A1 for use. This movable device can easily follow concrete transport equipment, promptly discharging wastewater and waste residue from the equipment. Furthermore, when the device becomes too heavy, trolleys B17 or C18 can be easily replaced. The replaced trolleys B17 or C18 can also be easily moved independently to place the collected wastewater and waste residue into the centralized treatment pool for further processing.
