Description

Technical Field

[0001] The utility model relates to the technical field of on-site emulsion explosive configuration equipment, in particular to a tunnel-type on-site mixed emulsion explosive truck configuration equipment. Background Art

[0002] On-site mixed emulsion explosive is an explosive that is instantaneously mixed at the blasting site and is mainly used for open-pit and underground blasting operations. Due to its high energy, high safety, and environmental protection characteristics, it is widely used in fields such as mining and earthwork projects. However, for large-section tunnel excavation blasting construction in infrastructure construction such as railways, highways, and hydropower stations, on-site mixed emulsion explosives have not been widely used.

[0003] Tunnel excavation blasting operations have the characteristics of small single-dose drug use, small blast hole diameter, small single-hole charge amount, etc., and there are numerous blast holes, and the height of the heading face can reach more than ten meters. At present, tunnel blasting operations use other equipment such as steel platforms and arch trolley platforms as operation platforms for charging.

[0004] However, this charging method relies on auxiliary equipment such as steel platforms and arch trolley platforms. During the charging process, the position of the auxiliary equipment needs to be repeatedly adjusted according to the charging position, and the movement and positioning of these auxiliary equipment are slow, which not only causes high labor intensity and low charging efficiency, but also increases the coordination difficulty of on-site construction.

[0005] Based on this, how to quickly and safely configure emulsion explosives and quickly and safely charge them while meeting the requirements of tunnel blasting has become an urgent problem to be solved. Content of the Utility Model

[0008] II. Specific Technical Solutions

[0010] Implementation principle, working principle: In this solution, a double-piston pump is used as the main conveying power component to convey the latex matrix and sensitizer from the latex matrix silo and the sensitizer silo to the end mixer for mixing together, so as to achieve the configuration of emulsion explosive. And all the required emulsion explosives are configured on-site, with a short retention period, thus effectively ensuring the stability of the emulsion explosive; the setting of the water ring can provide auxiliary conveying power between the double-piston pump and the end mixer, and better maintain the conveying efficiency of the latex matrix and the sensitizer.

[0011] As a preference: The whole latex matrix silo is funnel-shaped. At the outlet of the latex matrix silo, a three-way joint is connected by a flange. The second end of the three-way joint is connected to the double-piston pump through a pipeline, and a first gate valve is also arranged at the second end of the three-way joint; the third end of the three-way joint is sequentially connected with a second gate valve and a flange connection end; the beneficial effect of this preference is that when it is necessary to carry out the overall sewage discharge or feeding of the latex matrix silo, only the pipeline connected to the second end needs to be switched, and then the second end of the three-way joint is closed to carry out.

[0012] As a preference, the latex matrix silo is of a double-layer structure. A cavity is arranged in the middle of the double-layer structure of the latex matrix silo, and the cavity is used to introduce circulating water. The outer layer of the latex matrix silo is coated with a heat-insulating layer; the setting of the heat-insulating layer can effectively isolate the heat exchange between the latex matrix silo and the outside world, and then the circulating water introduced can keep warm or heat the latex matrix in the silo.

[0013] As a preference, a first pressure sensor, a first temperature sensor and a mixer are also arranged on the pipeline between the first output end of the double-piston pump and the input end of the water ring; through the setting of the mixer, the latex matrix in the pipeline can be well mixed, making the distribution of each component more uniform. The settings of the first pressure sensor and the first temperature sensor are beneficial to observing the state of the latex matrix.

[0014] As a preference, there are multiple sensitizer silos, which are respectively used to store catalysts and different types of sensitizers. An overflow port is arranged at the top of the sensitizer silo, and a first liquid level sensor is arranged inside the sensitizer silo; a first flowmeter is also arranged between the second output end of the double-piston pump and the input end of the water ring; through the combined cooperation of the first liquid level sensor and the flowmeter, the usage amount of the sensitizer can be well monitored.

[0015] As a preference, a second liquid level sensor is arranged in the latex matrix silo, and a second flowmeter is also arranged between the first output end of the double-piston pump and the input end of the water ring; through the settings of the second liquid level sensor and the second flowmeter, the usage amount of the latex matrix can be well monitored.

[0016] Preferably, a controller and a human-machine interface are further provided at the bottom of the installation rack. The controller is electrically connected to the first flowmeter, the second flowmeter, the first liquid level sensor, the second liquid level sensor, the first pressure sensor, and the first temperature sensor respectively. The controller is also electrically connected to the double plunger pump, the latex matrix bin, and the sensitizer bin. The beneficial effect of this preference is that the controller can control the double plunger pump through the data collected by each sensor and flowmeter, and can complete the fixed ratio configuration through the flow rates of the latex matrix and the sensitizer. It has powerful functions and can also monitor the latex matrix and the sensitizer well.

[0017] The beneficial effects of the present utility model are as follows:

[0018] This solution can safely and fully continuously configure emulsion explosives at the tunnel blasting site, and can effectively shorten the retention period of emulsion explosives before blasting, effectively ensuring the stability and effectiveness of emulsion explosives. Through the setting of the mixer, the components of the latex matrix can be kept stable during the transportation process of the latex matrix, so that each component of the latex matrix can be fully mixed with the sensitizer in the end mixer, and the effect is better. Also through the cooperation of the controller, flowmeter, weight sensor, and liquid level gauge, the usage amounts of the latex matrix and the sensitizer can be recorded in real time, the transportation efficiency of the latex matrix and the sensitizer can be intuitively judged, and then the ratio can be observed in real time, which is intuitive and convenient. The usage amounts of both can also be recorded, which is convenient for storage. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following elaborates on the preferred embodiments of the present utility model in conjunction with the accompanying drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] As Figures 1-4 shown:

[0027] A configuration device for a tunnel-type on-site mixed emulsion explosive vehicle, comprising an installation frame 100. A latex matrix bin 101 is installed on the upper part of the installation frame 100. A sensitizer bin 102, a double-piston pump 103, a water ring 104, and a terminal mixer 105 are respectively installed at the bottom of the installation frame 100. Specifically, the first input end of the double-piston pump 103 is connected to the latex matrix bin 101 through a pipeline. The second input end of the double-piston pump 103 is connected to the sensitizer bin 102. The first output end and the second output end of the double-piston pump 103 are connected to the input end of the water ring 104 through a pipeline. The output end of the water ring 104 is connected to the terminal mixer 105 through a pipeline.

[0028] In this solution, the double-piston pump 103 conveys the latex matrix and the sensitizer from the latex matrix bin 202 and the sensitizer bin 102 to the terminal mixer 105 for mixing together, thus realizing the configuration of emulsion explosives. The advantage is that the required emulsion explosives are all configured on-site with a short retention period, which effectively ensures the stability of the emulsion explosives. The setting of the water ring 104 can provide auxiliary conveying power between the double-piston pump 103 and the terminal mixer 105, and better maintains the conveying efficiency of the latex matrix and the sensitizer.

[0029] During implementation, there are specifically three sensitizer bins 102, which are respectively used to store catalysts and two kinds of sensitizers. An overflow port 112 is arranged at the top of the sensitizer bin 102. This facilitates the selection of a suitable sensitizer according to different latex matrices, with better effects. The setting of the overflow port can prevent the pressure in the sensitizer bin 102 from being too high.

[0030] During implementation, the overall latex matrix bin 101 of this solution is funnel-shaped. At the outlet of the latex matrix bin 101, a three-way joint 106 is connected by a flange. Among them, the first end of the three-way joint 106 is connected to the outlet of the latex matrix bin 101, the second end of the three-way joint 106 is connected to the double-piston pump 103 through a pipeline, and a first gate valve 107 is also provided at the second end of the three-way joint 106; the third end of the three-way joint 106 is successively connected to a second gate valve 108 and a flange connection end. When it is necessary to drain the latex matrix bin 101 as a whole, only by switching the connection to the second end to a sewage pipeline or a clean water pipeline, flushing and sewage discharge can be carried out; during feeding, closing the second end of the three-way joint can be carried out, and it is switched to connect to the latex matrix feeding pipeline; specifically, the latex matrix bin 101 is a double-layer structure, and a cavity 109 is provided in the middle of the double-layer structure of the latex matrix bin 101. A water circulation pipeline is provided in the cavity 109 to introduce circulating water. The outer layer of the latex matrix bin 101 is coated with a heat preservation layer 110. Through the setting of the heat preservation layer 110, the heat exchange between the latex matrix bin 101 and the outside can be effectively isolated, and the latex matrix in the bin can be kept warm or heated by the introduced circulating water.

[0031] During implementation, a controller 113 and a human-machine interface 114 are also fixedly provided at the bottom of the installation rack 100 of this solution; a first liquid level sensor is provided inside the sensitizer bin 102; on the pipeline between the first output end of the double-piston pump 103 and the input end of the water ring 104, a first pressure sensor, a second flowmeter, a first temperature sensor and a mixer 111 are successively connected. A first flowmeter is also provided between the second output end of the double-piston pump 103 and the input end of the water ring 104; a second liquid level sensor is provided in the latex matrix bin 101.

[0032] Specifically, the controller 113 is electrically connected to the first flowmeter, the second flowmeter, the first liquid level sensor, the second liquid level sensor, the first pressure sensor, and the first temperature sensor. The controller 113 is also electrically connected to the double-piston pump 103, the latex matrix bin 101, and the sensitizer bin 102; the advantage of this is that the controller can control the double-piston pump through the data collected by each sensor and flowmeter, and can complete the fixed ratio configuration through the flow rates of the latex matrix and the sensitizer. It has powerful functions and can also well complete the monitoring of the latex matrix and the sensitizer.
