Description

The collection-tank to warn a sewage-level of vacuum dump}

The present invention relates to a water level alarm recovery tank for a vacuum suction vehicle, and more particularly, a separate sensor having a simple structure and an electric valve operated by the sensor are installed on the top of the tank of the vacuum suction vehicle so as to be separated from each other. It is related with the water level recovery tank for the vacuum suction vehicle, which can effectively prevent excessive inflow of dirt and prevent the effect of work efficiency and cost reduction.

In general, in order to suck up and clean industrial and household waste, a vacuum pump is attached and a specially designed vacuum suction vehicle is frequently used. In the construction site or at home, sewage, dust, and other wastes in the sewer, which are difficult to be cleaned by human hands, are sucked through the pipe by the power of a pump, stored in a tank, and discarded.

As shown in FIG. 1, when the water level alarm recovery tank for a vacuum suction vehicle is filled with sludge and dirt by the suction force driven by the vacuum pump to the setting level in the main body 2 through the suction hose 1, the float is floated. Due to the buoyancy of (3), the stopper (4) connected to the float (3) blocks the air outlet (6) connected to the suction equipment (not shown) in order to prevent further inflow of dirt, and at the same time the rise of the float (3) By mechanically operating the limit switch 7 formed on the outside of the manhole 5, an alarm sounds so that the worker stops working.

However, the conventional water level recovery tank for the vacuum suction vehicle has a complicated structure and many malfunctions and failures. In particular, when the foreign matter is caught between the cap 4 and the air outlet 6, the air outlet 6 is completely closed. As a result, the alarm does not sound due to the non-operation of the limit switch 7, thereby preventing the operator from knowing when the work is finished. If sludge and dirt, etc. continue to be introduced, there may be a case to be introduced into the suction facility through the air outlet 6 to the body 2 (2).

In addition, the work efficiency and workability is deteriorated due to this, and there is a problem in that it takes a lot of expenses in production.

Accordingly, the present invention has been made to solve the above-described problems, the object of the present invention, the structure is simple in the vacuum suction water level alarm recovery tank has the effect of reducing the manufacturing cost, the sensing unit and the operating unit It is to provide a water level alarm recovery tank for a vacuum suction vehicle to be separated and complementary to each other.

Another object of the present invention is to provide a water level recovery tank for a vacuum suction vehicle that can be expected to improve the work efficiency and work stability by operating the valve electrically to effectively block excessive inflow of dirt beyond the setting level. .

These objects are provided in the water level alarm recovery tank for effectively blocking the air outlet and preventing excessive inflow of dirt, a suction hose for recovering sludge and dirt; A main body in which dirt collected by the suction hose is stored; A detector comprising a float floating along the electromagnet rod to detect the amount of sludge and dirt stored in the main body, and a sensor that recognizes the height of the float; And an air outlet attached to a keystone valve for preventing excessive inflow of dirt and sludge by preventing the discharge of air in the main body by the operation of the sensor of the sensing unit, and an air outlet connected to the main body. It can be achieved by a recovery tank.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to Figure 2 showing in detail the water level alarm recovery tank for a vacuum suction vehicle according to a preferred embodiment of the present invention, the sludge and dirt is moved by the suction force by the operation of the vacuum pump, the body ( And a suction hose 1 connected to 2).

Through this suction hose 1, sludge or dirt is moved to the main body 2 and stored.

The sludge and dirt moved to the main body 2 are connected to the main body 2 in a float 32 floating along the electromagnet rod 30 and having a vertical movement range set by the height adjusting units 34 and 36. And, the amount is recognized by the sensor 20, the sensor 38 is integrally attached to the upper portion.

When the sludge and the dirt reaches the setting level, the keystone valve 40 is supplied with power by the operation of the sensor 38, and the keystone valve 40 blocks the air outlet 42 to which the suction device is connected. The inflow of dirt is blocked.

Hereinafter, the assembly method and the operation mode of the water level alarm recovery tank for the vacuum suction vehicle according to the present invention will be described in detail.

The operator first operates a suction facility that includes a vacuum pump (not shown) where suction is required, and the spaces in the suction facility, the air outlet 42, the main body 2 and the suction hose 1 are sucked by the operation of the pump. As it is retracted, it maintains near vacuum in each space. The suction force generated at this time moves the sludge and the dirt through the suction hose (1) to the main body (2).

The incoming dirt is collected in the main body 2, but the amount is limited due to the limit of the capacity, so that the operator 20 is in communication with the middle upper end of the main body 2 so that the operator can easily know the fact. It is provided. The sensing unit 20 is connected to the electromagnet rod 30, and the float 32 is located floating along the electromagnet rod 30 as the amount of sludge and dirt introduced increases, the float 32 The setting level is determined by the height adjusting units 34 and 36. When the float 32 comes into contact with the height adjustment part 34 of the upper end, the sensor 38 detects the height measured by the electromagnet rod 30.

3 is a schematic view showing an operating state of the water level alarm recovery tank by the sensor 38. The sensor 38, which senses that the tank has reached its limit, sends a signal to the controller 44. In response, the controller 44 applies power to the keystone valve 40 to electrically block the air outlet 42. By the keystone valve, no further vacuum can be maintained in the suction facility and the air outlet 42 and the free body 2, so that the suction input is lost, so that excess sludge and dirt cannot be introduced. At the same time, the controller 44 causes the alarm to operate so that the operator can stop the work.

As a result, according to the water level alarm recovery tank for the vacuum suction vehicle according to the present invention, the structure is simple and has the effect of reducing the production cost, by preventing the malfunction and failure by separating the sensing unit and the operating unit to complement each other. It can work.

In addition, the valve is electrically operated to effectively block excessive inflow of dirt beyond the setting level, and thus there is an advantage in that work efficiency and work stability can be expected.

While preferred embodiments of the present invention have been described above, it will be understood by those skilled in the art that various modifications and changes can be made without departing from the scope of the appended claims.
