Description

Safe filling device

Technical Field

The utility model relates to a safe filling device.

Background

In the filling process of some dangerous chemicals, especially more than 200L of packaging barrels, because the time of filling one barrel is long, operators cannot pay attention to the filling liquid level in the filling process, sometimes the operators leave temporarily, overflow and leakage of the chemicals caused by failure of timely closing of a filling valve occur sometimes, and the leaked chemicals cause great harm to personnel and environment. The invention can automatically stop filling even if the valve is in an open state after the liquid is filled to a certain liquid level through simple modification.

Patent application No.: 201520528452.7 safe filling device: the patent discloses a safe filling device, which relates to a feeding device and comprises a rack, a liquid storage tank, a piston cylinder, a check valve and a connecting rod slider mechanism, wherein the connecting rod slider mechanism comprises a slider arranged on the rack, a first connecting rod and a second connecting rod, one ends of the first connecting rod and the second connecting rod are hinged on the slider, the piston cylinder comprises a piston rod and a cylinder barrel, a tension spring is sleeved outside the piston rod, the piston rod is hinged with the other end of the first connecting rod in the cylinder barrel, a liquid inlet pipe and a liquid outlet pipe are communicated on the cylinder barrel, the liquid inlet pipe is communicated with the liquid storage tank and the cylinder barrel, the check valve flowing to the piston cylinder is arranged on the liquid inlet pipe, the check valve flowing out of the piston cylinder and a retaining ring sleeved on the liquid outlet pipe are arranged on the liquid outlet pipe, and the retaining ring is hinged with the other end of the second connecting rod, so that liquid can not be filled to the outside when no bottle exists.

Patent numbers: cn201721344136.x a filling head: the utility model discloses a filling head, it includes the body, the flowmeter, the filter screen with spout the board, the body is the cylinder of step form, the flowmeter sets up in the big footpath of cylinder and holds, the filter screen is upper and lower two-layer and sets up respectively in the path end of cylinder, spout the terminal surface that board and cylinder footpath end are connected, and spout the board and adopt integrated into one piece processing with the body to form, thereby it adopts to set up double-deck filter screen structure and overcomes prior art impact force big and impurity and do not obtain filterable defect, overall structure scientific and reasonable, simple compactness, use and simple to operate, the operation is safe and reliable, can improve the quality and the production efficiency of cold tea beverage, it extensively is applicable to the supporting use of processing of cold tea beverage.

In the prior art, the automatic closing of the valve is generally realized through the association of the valve and an electric control system and the real-time data feedback of the liquid level or the weight. The cost of the whole system for modifying the equipment is high. Since most dangerous chemicals are flammable and explosive, all facilities used in the production environment must reach a certain explosion-proof level, which greatly increases the cost of the electric control system.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a safe filling device aims at through utilizing simple physical principle, can reach the function of preventing leaking equally. The transformation process is convenient, and the cost is low.

In order to achieve the purpose, the technical scheme of the utility model is to design a safe filling device, which comprises a finished product tank, a packaging barrel, a discharging pipe and an air return pipe; the discharge pipe extends out of the bottom of the finished product tank and is inserted into the packaging barrel; the air return pipe extends out of the top of the finished product tank and is inserted into the packaging barrel; the air return pipe lower extreme is located near pail pack upper portion import, and the degree of depth that the discharging pipe lower extreme stretched into the pail pack is greater than the degree of depth that the air return pipe lower extreme stretched into the pail pack.

Further, a first valve is arranged on the discharge pipe; and a second valve is arranged on the air return pipe.

Furthermore, the upper part of the finished product tank is provided with a feeding pipe and a feeding exhaust pipe.

Further, a third valve is arranged on the feeding pipe; and a fourth valve is arranged on the feeding exhaust pipe.

The utility model has the advantages and the beneficial effects that: the utility model relates to a safe filling device utilizes the atmospheric pressure principle, through simple transformation, reaches the anti-overflow function of filling mouth.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Wherein, finished product jar 1, pail pack 2, discharging pipe 3, muffler 4, first valve 5, second valve 6, inlet pipe 7, feeding blast pipe 8, third valve 9, fourth valve 10.

Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

Example (b):

a safe filling device comprises a finished product tank 1, a packaging barrel 2, a discharging pipe 3 and an air return pipe 4; the discharge pipe 3 extends out of the bottom of the finished product tank 1 and is inserted into the packaging barrel 2; the air return pipe 4 extends out of the top of the finished product tank 1 and is inserted into the packaging barrel 2; the lower end of the air return pipe 4 is positioned near the inlet on the upper part of the packaging barrel 2, and the depth of the lower end of the discharge pipe 3 extending into the packaging barrel 2 is larger than the depth of the lower end of the air return pipe 4 extending into the packaging barrel 2.

A first valve 5 is arranged on the discharge pipe 3; and a second valve 6 is arranged on the air return pipe 4.

And the upper part of the finished product tank 1 is provided with a feeding pipe 7 and a feeding exhaust pipe 8.

A third valve 9 is arranged on the feeding pipe 7; and a fourth valve 10 is arranged on the feeding exhaust pipe 8.

The principle is as follows: as shown in fig. 1, the finished tank 1 can be filled by opening the third valve 9 and the fourth valve 10. When the logistics in the finished product tank 1 needs to be filled into the packaging barrel 2, the third valve 9 and the fourth valve 10 are closed before filling; then the first valve 5 and the second valve 6 are opened; the material flows into pail pack 2, and the air flows into 1 upper portion of finished product jar through muffler 4, and along with the rising of pail pack 2 interior liquid level, when the liquid level crosses muffler 4 lower extreme, muffler 4 can't normally return air, and the material will stop flowing out.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the technical principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
