[0039] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0040] Please refer to Figure 1 The specific embodiment of the utility model relates to an automatic feeding system for an emulsion explosive foaming agent, comprising:

[0041] Preparation tank 1;

[0042] A first connecting pipe 2, the starting end of which is connected to one side of the bottom of the preparation tank 1;

[0043] A first valve 21, wherein the first valve 21 is connected to the first connecting pipe 2;

[0044] A second connecting pipe 3, the starting end of which is connected to the bottom of the preparation tank 1;

[0045] A second valve 31, wherein the second valve 31 is connected to the second connecting pipe 3;

[0046] A third connecting pipe 4, the starting end of which is connected to the ends of the first connecting pipe 2 and the second connecting pipe 3 respectively through a three-way joint;

[0047] A foaming agent tank 5, the end of the third connecting pipe 4 is connected to the foaming agent tank 5, and the foaming agent tank 5 is located below the preparation tank 1;

[0048] A first liquid level gauge 51, wherein the first liquid level gauge 51 is connected to the foaming agent tank 5, and the first liquid level gauge 51 is provided with a low liquid level threshold L1 and a high liquid level threshold L2;

[0049] The control box is electrically connected to the first valve 21 and the first liquid level meter 51; the control box is used to switch between the automatic mode and the manual mode;

[0050] In the automatic mode, the second valve 31 is normally closed, and the opening and closing of the first valve 21 is controlled according to the signal of the first liquid level meter 51. When the liquid level reaches L1, the first valve 21 is controlled to be opened, and when the liquid level reaches L2, the first valve 21 is controlled to be closed;

[0051] In the manual mode, the first valve 21 is normally closed, and the second valve 31 is manually opened and closed according to the liquid level displayed by the first liquid level gauge 51 .

[0053] In the above embodiments, it should be noted that the manual mode is a supplement to the automatic mode, and is used to deal with the foaming agent refilling operation under abnormal production conditions, such as: 1. The damage of the first liquid level gauge 51 or the first valve 21 leads to the failure of normal refilling; 2. When the amount of foaming agent does not reach the upper and lower limit control amount of the first liquid level gauge 51 (limited by the working principle of the switch liquid level gauge), the liquid volume of the preparation tank 1 is emptied, and a new batch of foaming agent can be prepared. The opening and closing of the first valve 21 in the automatic mode is completely controlled by the upper and lower limits of the first liquid level gauge 51, and cannot be manually controlled. The purpose is to achieve automatic production refilling without human operation; in the manual mode, the opening and closing of the second valve 31 can be controlled by the manual button on the control box, and the normally closed contact of the upper limit value of the first liquid level gauge 51 is added to interlock the control valve closure to prevent the safety hazard of excessive liquid refilling of the foaming agent tank 5 (for production) overflowing the tank body in the manual mode. The purpose of the manual mode is to deal with the foaming agent refilling operation under abnormal production conditions, and the manual control operation is flexible to deal with emergencies.

[0063] A quantitative control system is electrically connected to the third valve 61, the turbine flowmeter 62 and the second liquid level meter 12 respectively.

[0064] As a preferred embodiment, the second liquid level gauge 12 is a magnetic flap liquid level gauge.

[0065] As a preferred embodiment, the third valve 61 is a solenoid valve.

[0066] Working principle:

[0067] During preparation: When the preparer is feeding and preparing the materials, he presses the preparation button of the automatic feeding system, the first valve 21 and the second valve 31 are closed, and the personnel begin to feed the foaming agent raw materials. Then, he presses the start button on the quantitative control system, and the third valve 61 is opened. Water begins to be added to the preparation tank 1 through the water adding pipeline 6. After the set water addition amount is reached, the third valve 61 is closed, and the water addition is stopped. The stirring button is pressed to start stirring and preparing. The stirring motor is provided with a time relay, and the stirring is stopped after the set time is reached.

[0068] Automatic feeding: After the stirring motor is started, the automatic button of the automatic feeding system is turned on. At this time, the opening and closing of the first valve 21 is controlled by the upper and lower limits of the first liquid level gauge 51. When the lower limit value L1 is reached, the first valve 21 is turned on for automatic feeding. When the liquid reaches the upper limit value L2, the first valve 21 is closed and the feeding is stopped.

[0069] Manual feeding: Turn on the manual button of the automatic feeding system, the first valve 21 is interlocked and normally closed, and the second valve 31 is manually opened and closed according to the first liquid level gauge 51;

[0070] The automatic feeding system is configured with automatic and manual buttons interlocked with each other, one on and two off, and no more than two buttons can be started at the same time to prevent misoperation;

[0071] The automatic feeding system for emulsion explosive foaming agent can be applied to the situation where there is a height difference between the preparation tank 1 and the foaming agent tank 5 (for production). According to local conditions, the preparation tank 1 can be set with a capacity larger than the volume of the foaming agent tank 5 according to actual production needs to prepare the stock;

[0072] The automatic feeding system for emulsion explosive foaming agent does not add PLC and other computer control programs, but is a circuit control of pure electrical components;

[0073] In summary, the utility model combines the layout of the existing workshop, utilizes the high and low liquid level difference to automatically replenish materials, saves the pumping link, reduces excessive economic investment and large workshop infrastructure; reduces labor input, eliminates the long-term manual batching and manual replenishment links, and greatly reduces labor intensity; has complete functions, and the foaming agent can be automatically and manually replenished according to the remaining amount in the tank to prevent material shortage, and the preparation amount can be set according to the actual production situation; the operability is simple and convenient, after the raw materials are manually input, the preparation can be turned on to realize subsequent automatic replenishment; no computer control programs such as PLC are added, and the circuit control of pure electrical components is simple and easy, and the implementation difficulty, maintenance cost and transformation cost are low.
