Description

Technical Field

[0001] This utility model relates to the field of sanitation vehicle technology, specifically to a lightweight, high-capacity sewage suction truck tank structure. Background Technology

[0002] Existing vacuum truck tanks typically use a single-tank structure for storing sewage and waste. This design has the following problems:

[0003] 1. Because the vacuum truck uses a vacuum pump to evacuate the tank, the tank needs to withstand a large air pressure, resulting in a complex tank structure, a large weight, and a small tank volume.

[0004] 2. Existing vacuum tanks are generally made large to store sewage. To meet the requirements of suction speed, a large-displacement vacuum pump is required. This not only increases the weight of the upper structure, but also increases vehicle cost and fuel consumption.

[0005] Therefore, a new type of tank structure for vacuum trucks is needed to address the shortcomings of existing technologies. Summary of the Invention

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a lightweight, high-capacity vacuum truck tank structure that can meet the operational requirements using a small displacement vacuum pump, while also allowing for a large loading capacity of the vacuum truck tank.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A lightweight, high-capacity vacuum truck tank structure includes a pressure tank and a storage tank connected by a connecting pipe, and a connecting valve is connected to the connecting pipe.

[0009] The pressure tank is used to pump sewage. The pressure tank is connected to the vacuum pump and pipeline of the sewage suction truck. The vacuum pump of the sewage suction truck is used to evacuate the pressure tank, and the sewage suction truck pipeline is used to perform sewage suction operations.

[0010] The storage tank is used to store wastewater pumped by the pressure tank. An exhaust valve is connected to the top of the storage tank, and a drain valve is connected to the bottom of the storage tank.

[0011] Furthermore, the connecting pipe and connecting valve are located inside the maintenance compartment.

[0012] Furthermore, the connecting valve, the exhaust valve, and the drain valve are all pneumatic valves.

[0013] This utility model adopts the above technical solution, which divides the single tank of the sewage suction truck into a pressure tank and a storage tank. The pressure tank is used to suck up sewage, and the storage tank is used to store sewage. The two tanks are connected by a connecting pipe. The reduced volume of the pressure tank allows the use of a small displacement vacuum pump to meet the operation requirements, thereby reducing the overall vehicle cost and fuel consumption. At the same time, the storage tank is enlarged and lightweight, thereby achieving the goal of reducing the weight of the upper structure and increasing the sewage volume.

[0014] In summary, this utility model has a simple and reliable structure, which can reduce the weight of the sewage suction truck tank and increase the water capacity of the sewage suction truck tank. At the same time, the use of a small displacement vacuum pump can not only reduce the overall vehicle cost but also reduce operating fuel consumption. Attached Figure Description

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0016] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0017] like Figure 1 As shown, the present invention discloses a lightweight, high-capacity sewage suction truck tank structure, which includes a pressure tank 1 and a storage tank 4 connected by a connecting pipe. A connecting valve 6 is connected to the connecting pipe, and the connecting pipe and the connecting valve 6 are located inside the maintenance compartment 2.

[0018] Pressure tank 1 is used to pump sewage. Pressure tank 1 is connected to the vacuum pump and pipeline of the sewage suction truck. The vacuum pump of the sewage suction truck is used to evacuate pressure tank 1, and the sewage suction truck pipeline is used to perform sewage suction operation.

[0019] Storage tank 4 is used to store the sewage pumped by pressure tank 1. The top of storage tank 4 is connected to vent valve 3, and the bottom of storage tank 4 is connected to drain valve 5.

[0020] In a preferred embodiment, the connecting valve 6, the exhaust valve 3, and the drain valve 5 are all pneumatic valves.

[0021] When pressure tank 1 is full of sewage, connecting valve 6 and exhaust valve 3 are opened, and sewage discharge valve 5 is closed. At this time, the vacuum pump of the sewage suction truck is put into the return operation state. The vacuum pump inflates pressure tank 1, so that the sewage in pressure tank 1 flows into storage tank 4 through connecting pipe, thereby emptying the volume in pressure tank 1 so that the vehicle can perform sewage suction operation again.

[0022] When the vehicle is transporting sewage, the connecting valve 6, the exhaust valve 3, and the sewage discharge valve 5 are all closed to prevent the gas inside the tank from polluting the environment and causing secondary pollution.

[0023] When the vehicle arrives at the sewage discharge point, close the exhaust valve 3 and open the connecting valve 6 and the sewage discharge valve 5 at the same time, so that the vacuum pump of the sewage suction truck is in the back discharge operation state, and the sewage in the pressure tank 1 and storage tank 4 is discharged faster.

[0024] This utility model divides the single tank of the sewage suction truck into a pressure tank 1 and a storage tank 4. The pressure tank 1 is used to suction sewage, and the storage tank 4 is used to store sewage. The two tanks are connected by a connecting pipe. The reduced volume of the pressure tank 1 allows the use of a small displacement vacuum pump to meet the operation requirements, thereby reducing the overall vehicle cost and fuel consumption. At the same time, the storage tank 4 is enlarged and lightweight, thereby achieving the goal of reducing the weight of the upper structure and increasing the sewage volume.

[0025] The specific embodiments of this utility model have been described above. However, those skilled in the art should understand that this is only an example. Those skilled in the art can make various changes or modifications to this embodiment without departing from the principle and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
