Abstract
The utility model discloses an anti-overflow device for a combined sewage-suction vehicle for preventing sewage in a sewage suction tank from overflowing. The anti-overflow device comprises the sewage suction tank disposed on a vehicle body, a vacuum pump, and a sewage suction pipe for the sewage suction tank to suck sewage, wherein an anti-overflow device is disposed between the sewage suction tank and the vacuum pipe. According to the anti-overflow device, problems that workloads of sanitation workers are increased because of a lack of the anti-overflow device on conventional combined sewage-suction vehicles, and that the vacuum pipe is damaged by impurities such as sewage entering the vacuum pipe are solved. The anti-overflow device is scientific and reasonable in structure, low in manufacturing costs, and convenient to popularize and apply.
Description
Technical field
The utility model relates to sewage conduct mediation equipment technical field, is specifically related to a kind of combined suction sewage truck anti-overflow device.
Background technology
Combined suction sewage truck is mainly used in sewage, mud and the sandstone, large-scale of all kinds of underground sewers in city, catch-basin and inspection shaft; The suction of block, transport, remove stage makeup and costume, can be used for the desilting and the mediation in suction, transportation and small-sized river course of sewage, industrial waste oil and the waste water of large-scale industrial enterprise simultaneously.At present, existing suction-type sewer scavenger is observed sewage quantity in the dirt-absorption tank through the liquid level window on the liquid level meter usually in the soil pick-up process; If the sanitationman has carelessness slightly in number of observation with above the time, sewage canful in the sewage jar just might take place, thereby sewage and mud get in the vacuum pump; Cause vacuum pump to be out of order, even the existence of the problems referred to above take place in the accident of damaging; Not only increase sanitationman's workload, and brought harm for the normal soil pick-up work of suction-type sewer scavenger.
Summary of the invention
The technical problem that the utility model will solve provides a kind of combined suction sewage truck anti-overflow device; The utility model not only efficiently solves existing combined suction sewage truck because of there not being the anti-overflow device, the problem that causes sanitation worker's workload to increase, and solved impurity entering vacuum pump such as sewage; The problem that causes vacuum pump to damage; The utility model is scientific and reasonable for structure, and low cost of manufacture is easy to utilize.
The utility model is realized through following technical scheme:
A kind of combined suction sewage truck anti-overflow device is used for preventing that the sewage of dirt-absorption tank from overflowing, and comprises dirt-absorption tank, vacuum pump of installing on the car body and the dirt sucking tube that is used for the dirt-absorption tank soil pick-up, is provided with the anti-overflow device between said dirt-absorption tank and the vacuum pump.
The further Technological improvement plan of the utility model is:
Said anti-overflow device comprises air filter, pipeline A, pipeline B and safety valve; Be provided with filter screen in the air filter; The air filter lower end is connected with dirt-absorption tank through pipeline A; The air filter upper end is communicated with vacuum pump through pipeline B, and pipeline B is provided with safety valve, and the interface of air filter and pipeline B is provided with ball float.
The utility model compared with prior art has following obvious advantage:
One, the utility model is provided with the anti-overflow device, and the sanitationman does not regularly observe the soil pick-up amount of sewage in the dirt-absorption tank at needs, thereby has alleviated sanitationman's workload;
Two, be provided with filter screen in the air filter of the utility model anti-overflow device and can effectively block impurity such as mud and get in the vacuum pump, thereby improved the job security of vacuum pump.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1, the utility model is used for preventing that the sewage of dirt-absorption tank 2 from overflowing, and comprises dirt-absorption tank 2, vacuum pump of installing on the car body 9 and the dirt sucking tube 1 that is used for dirt-absorption tank 2 soil pick-ups, is provided with the anti-overflow device between dirt-absorption tank 2 and the vacuum pump 9; The anti-overflow device comprises air filter 4, pipeline A3, pipeline B7 and safety valve 8; Be provided with filter screen 5 in the air filter 4; Air filter 4 lower ends are connected with dirt-absorption tank 2 through pipeline A3; Air filter 4 upper ends are communicated with vacuum pump 9 through pipeline B7, and pipeline B7 is provided with safety valve 8, and air filter 4 is provided with ball float 6 with the interface of pipeline B7.
Sketch the course of work of the utility model in conjunction with Fig. 1:
Combined suction sewage truck is in the soil pick-up process, and vacuum pump 9 is through the air in pipeline B7, the pipeline A3 suction dirt-absorption tank 2, makes to form negative pressure in the dirt-absorption tank 2; The dirt sucking tube 1 suction sewage of dirt-absorption tank 2 through being provided with on it, when canful appearred in sewage in the dirt-absorption tank 2, sewage got in the air filter 4 along pipeline A3; Impurity such as mud are intercepted in air filter 4 lower ends through filter screen 5; Wastewater level rises in the air filter 4, drives ball float 6 simultaneously, and ball float 6 rises with water level the water inlet of pipeline B7 is blocked; Make sewage can not get into pipeline B7, open the safety-valve 8 this moment to ensure that vacuum pump 9 is not damaged.
The utility model has reached the foregoing invention purpose in sum.
