Description

TECHNICAL FIELD

[0001] The utility model relates to a sewage suction truck technical field especially has automatic cleaning function's cleaning sewage suction truck. BACKGROUND

[0002] Sewage suction truck is the collection, the transfer cleaning transportation sludge, sewage, avoids the secondary pollution new type environmental sanitation vehicle. Sewage suction truck has the function of self-suction and self-discharge, and is fast in working speed, large in capacity, convenient in transportation, and is suitable for collecting and transporting liquid substances such as excrement, slurry and crude oil. The working principle of sewage suction truck is mainly based on siphon principle. When the excrement suction hose is immersed in liquid surface, the air in the tank is sucked, and the pressure in the tank is gradually reduced due to the inability to be supplemented, so that the excrement enters the tank through the excrement suction hose under the action of atmospheric pressure. When the siphon pipe approaches the tank bottom, air is continuously discharged into the tank, and the pressure in the tank rises due to the inability to discharge air, and the excrement is discharged out of the tank through the siphon pipe and the excrement suction hose under the action of compressed air.

[0003] The existing sewage suction truck is mainly composed of a power takeoff, a transmission shaft, a vacuum sewage pump, a pressure tank body, a hydraulic part, a pipe network system, a vacuum pressure gauge, a sewage viewing pipe and a hand washing device. After the sewage suction and discharge of the sewage viewing pipe of the sewage suction truck, the inner wall will adhere to the dirt, and if it is not cleaned for a long time, there will be a serious odor, and the accumulation of the adhering matter will also affect the observation and use. Therefore, it is necessary to manually remove the sewage viewing pipe for cleaning, which is complicated and time-consuming. SUMMARY

[0004] The utility model aims at providing a cleaning sewage suction truck with automatic cleaning function, which increases a branch waterway on the high-pressure pump outlet pipe and connects the sewage viewing pipe through a three-way valve to complete automatic cleaning.

[0005] In order to solve the above technical problems, the technical scheme of the utility model is as follows: a cleaning sewage suction truck with automatic cleaning function, characterized by comprising a tank body, a high-pressure pump arranged at the bottom of the tank body, a high-pressure pump outlet pipe connecting the inside of the tank body with the high-pressure pump, a sewage viewing pipe and a sewage viewing pipe cleaning water pipe arranged at one side of the tank body, and a valve connecting the high-pressure pump outlet pipe with the sewage viewing pipe cleaning water pipe.

[0006] Improvement on the above technical scheme: the valve is a three-way valve.

[0007] Further improvement on the above technical scheme: the sewage viewing pipe is a transparent pipe body for displaying the liquid level height of the dirt in the tank body.

[0008] Still further improvement on the above technical scheme: the sewage viewing pipe is vertically installed on the side wall of the tank body, and the two ends of the sewage viewing pipe are communicated with the inside of the tank body. Beneficial effects

[0009] The cleaning and vacuuming truck with automatic cleaning function described in this invention adds a branch water path to the outlet pipe of the high-pressure pump, and connects this branch water path to the sight glass via a three-way valve, thereby achieving automatic cleaning of the sight glass. This innovative design effectively solves the problems existing in the prior art, namely, after the sewage suction and discharge work is completed, dirt easily adheres to the inner wall of the sight glass, and if it is not cleaned for a long time, it will produce a serious odor. In addition, the large amount of dirt adhering to it will also affect the observation of the internal condition of the sight glass. In the past, the sight glass had to be removed for cleaning, which was not only cumbersome but also time-consuming and labor-intensive. The automatic cleaning function of this invention greatly simplifies the cleaning process, improves work efficiency, and reduces labor costs. Attached Figure Description

[0010] To more clearly illustrate the technical solutions of this utility model embodiment, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0011] Figure 1 This is a schematic diagram of the structure of this utility model.

[0012] The components represented by each number in the attached diagram are listed below: 1. High-pressure pump; 2. High-pressure pump outlet pipe; 3. Three-way valve; 4. Sight pipe / cleaning water pipe; 5. Sight pipe; 6. Tank. Detailed Implementation

[0013] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0014] Please see Figure 1 As shown, a cleaning and vacuuming truck with automatic cleaning function includes a tank 6. A high-pressure pump 1 is installed at the bottom of the tank 6. The high-pressure pump 1 is connected to the inside of the tank 6 through a high-pressure pump outlet pipe 2. A sight tube 5 and a sight tube cleaning water pipe 4 are installed on one side of the tank 6. The high-pressure pump outlet pipe 2 is connected to the sight tube cleaning water pipe 4 through a valve 3. The valve 3 is a three-way valve. The sight tube 5 is a transparent tube used to display the liquid level of the dirt inside the tank 6. The sight tube is vertically installed on the side wall of the tank 6, and both ends of the sight tube 5 are connected to the inside of the tank 6.

[0015] During work:

[0016] The suction truck is parked as close as possible to the working point.

[0017] The straight-through cock handle of the oil return tank is turned to an angle of about 45° with the axis of the oil inlet pipe. The oil inlet pipe should have lubricating oil flowing through it.

[0018] The walkway tank side door is opened, the suction hose is taken out and swung back without bending.

[0019] The suction hose is pulled as deep as possible into the sewage to ensure that the end of the hose is always below 300 mm from the liquid surface during operation.

[0020] The operator can observe the liquid surface through the observation mirror on the rear head. When the liquid surface reaches the middle of the observation mirror, the driver should be notified and the suction hose should be pulled away from the ground or the four-way valve should be closed.

[0021] Before the self-unloading tank is unloaded, the locking bolt should be loosened and the rear tank door should be lifted to the desired angle. When the tank is fully loaded, the tank should not be lifted with the rear tank door closed, otherwise there is a risk of overturning.
