Description

Technical Field

[0001] This utility model belongs to the technical field of mining blasting devices, and relates to a charging device for a detonator-transmitting spacer. Background Technology

[0002] In the mining process, drilling and blasting are crucial technological steps, and the blasting effect directly impacts subsequent mining efficiency and costs. In open-pit and underground mine drilling and blasting operations, especially in medium-deep hole blasting, air-spaced explosive blasting techniques are frequently employed.

[0003] Industrial explosives can be divided into packaged explosives and field-mixed explosives. Compared with packaged explosives, field-mixed explosives have advantages such as high safety, low cost, accurate measurement, and high degree of automation. When using field-mixed explosives, air gap loading is usually adopted.

[0004] Air-spaced charging can reduce the explosion pressure inside the borehole, reduce or even avoid the impact and crushing of ore and rock caused by coupled charging, reduce over-crushing of ore and rock, expand the fracture zone, and improve the effective utilization rate of explosive blasting energy, thereby reducing explosive consumption per unit and minimizing the impact. It is one of the effective technical means to improve blasting effects, reduce blasting vibration, and reduce explosive consumption per unit in open-pit mines. However, when using existing detonator spacers and field-mixed explosives to achieve air-spaced charging, the emulsion explosive must be injected into the cartridge of the detonator spacer at the borehole opening before the spacer is placed into the borehole, which is a complex process. Moreover, during the injection process, the air inside the cartridge of the detonator spacer cannot be expelled, preventing the emulsion explosive from filling the entire cartridge and thus affecting the blasting effect. Utility Model Content

[0005] The purpose of this invention is to provide a charging device for a detonator that can transmit explosives, which solves the problem that existing detonator-transmitter spacers cannot fill the entire cartridge with emulsion explosives during charging.

[0006] The technical solution adopted by this utility model is a charging device for a detonator spacer, including a tray, a cartridge, an exhaust pipe and a one-way valve. The one-way valve is installed on the exhaust pipe. The bottom of the tray is hollow and connected to the top of the cartridge. The exhaust pipe passes through the tray, with one end of the exhaust pipe located at the top of the tray and the other end fixed to the bottom of the side wall of the cartridge and connected to the inside of the cartridge.

[0007] The one-way valve is installed at the end of the exhaust pipe located at the top of the tray, and the outlet end of the exhaust pipe is connected to the inlet end of the one-way valve.

[0008] The check valve can be any one of the following: spring-loaded check valve, straight-through check valve, right-angle check valve, or plastic diaphragm check valve.

[0009] The tray and the cartridge are connected by threads.

[0010] The tray consists of a flexible disc at the top and a connector at the bottom, which are bonded together.

[0011] The connector has an internal thread on its bottom inner wall and an external thread that mates with the internal thread on its top outer wall.

[0012] The elastic disc is made of rubber.

[0013] The cartridge is made of PVC and is sealed at the bottom.

[0014] The exhaust pipe is a flexible venting hose.

[0015] The beneficial effects of this utility model are as follows: (1) By setting an exhaust pipe in the detonator, one end of the exhaust pipe passes through the tray and is located at the top of the tray, and the other end is fixed to the bottom of the side wall of the cartridge and connected to the inside of the cartridge. During the loading process, the air in the cartridge of the detonator is discharged through the exhaust pipe, ensuring that the emulsion explosive completely fills the cartridge of the detonator after loading. (2) By installing a one-way valve at the end of the exhaust pipe located at the top of the tray, the exhaust pipe outlet end is connected to the one-way valve inlet end, the air in the explosive spacer cartridge is discharged during the explosive process and the emulsion explosive is prevented from entering the exhaust pipe from the exhaust pipe outlet end and blocking the exhaust pipe. (3) The explosive charging device for the explosive spacer is composed of a tray, cartridge, exhaust pipe and one-way valve. It has a simple structure and is easy to manufacture. When used, the empty explosive spacer can be placed directly in the borehole and then the normal explosive operation can be carried out, which effectively simplifies the construction process.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0019] Example 1 See Figure 1A detonator loading device for a detonator spacer includes a tray 2, a cartridge 3, an exhaust pipe 4, and a one-way valve 5. The bottom of the tray 2 is hollow and connected to the top of the cartridge 3. The exhaust pipe 4 passes through the tray 2, with one end (the outlet) located at the top of the tray 2 and the other end (the inlet) fixed to the bottom of the side wall of the cartridge 3 and connected to the interior of the cartridge 3. The one-way valve 5 is installed at the end of the exhaust pipe 4 located at the top of the tray 2, and the outlet end of the exhaust pipe 4 is connected to the inlet end of the one-way valve 5.

[0020] See Figure 2 When using the explosive charging device for the explosive-transmitting spacer of this utility model, the device is first placed in the borehole 1, with the outer edge of the tray 2 fitting against the inner wall of the borehole 1. A cavity is formed between the cartridge 3 and the borehole 1, filled with air 7. During charging, the injection pipe from the explosive mixing vehicle is inserted into the borehole 1, and then emulsion explosive is injected into the cartridge. During the charging process, the exhaust pipe discharges the air 7 from the bottom of the explosive-transmitting spacer cartridge, ensuring that the emulsion explosive completely fills the explosive-transmitting spacer cartridge after charging. When the cartridge is about to be filled with emulsion explosive, the injection pipe is slowly withdrawn while injecting the explosive. A one-way valve is installed at the exhaust end of the exhaust pipe, which can discharge the air 7 from the explosive-transmitting spacer cartridge during the charging process and prevent emulsion explosive from entering the exhaust pipe from the exhaust end and blocking the exhaust pipe.

[0021] Example 2 A charging device for a detonator spacer includes a tray 2, a cartridge 3, an exhaust pipe 4, and a one-way valve 5. The bottom of the tray 2 is hollow and connected to the top of the cartridge 3. The tray 2 and the cartridge 3 are threaded together. The exhaust pipe 4 passes through the tray 2, with one end (the outlet) located at the top of the tray 2 and the other end (the inlet) fixed to the bottom of the side wall of the cartridge 3 and connected to the interior of the cartridge 3.

[0022] When using the explosive charge device for the detonator spacer, the device is placed in the borehole 1, the outer edge of the tray 2 is in contact with the inner wall of the borehole 1, and a cavity is formed between the cartridge 3 and the borehole 1, which is filled with air 7.

[0023] This invention features an exhaust pipe installed in the detonator. One end of the exhaust pipe passes through the tray and is located at the top of the tray, while the other end is fixed to the bottom of the side wall of the cartridge and connected to the inside of the cartridge. During the loading process, the air 7 in the cartridge of the detonator is discharged through the exhaust pipe, ensuring that the emulsion explosive completely fills the cartridge of the detonator after loading.

[0024] One-way valve 5 is installed at the end of exhaust pipe 4 located at the top of tray 2, and the outlet end of exhaust pipe 4 is connected to the inlet end of one-way valve 5.

[0025] In this embodiment, the one-way valve 5 is a spring-loaded one-way valve. The spring-loaded one-way valve mainly consists of a valve body, a valve disc, and a spring. The valve body has an inlet and an outlet. The valve disc is opened and closed under the action of the spring. When fluid flows into the valve body from the inlet, the pressure of the fluid will overcome the pressure of the spring and push the valve disc to open, allowing the fluid to pass smoothly through the valve port. When the fluid attempts to flow in the opposite direction from the outlet, the valve disc will close due to the elastic force of the spring, preventing the fluid from flowing back. This process ensures that the fluid can only flow in one direction and prevents the occurrence of backflow.

[0026] This invention installs a spring-loaded one-way valve at the end of the exhaust pipe located at the top of the tray. The outlet end of the exhaust pipe is connected to the inlet end of the one-way valve. During the application of explosives, the air 7 in the explosive spacer cartridge can be discharged, and the emulsion explosive can be prevented from entering the exhaust pipe from the outlet end and blocking the exhaust pipe.

[0027] Example 3 A charging device for a detonator spacer includes a tray 2, a cartridge 3, an exhaust pipe 4, and a one-way valve 5. The bottom of the tray 2 is hollow and connected to the top of the cartridge 3. The tray 2 and the cartridge 3 are threaded together.

[0028] The exhaust pipe 4 passes through the tray 2. One end of the exhaust pipe 4, i.e. the air outlet, is located at the top of the tray 2, and the other end, i.e. the air inlet, is fixed to the bottom of the side wall of the cartridge 3 and is connected to the inside of the cartridge 3.

[0029] This invention features an exhaust pipe installed in the detonator. One end of the exhaust pipe passes through the tray and is located at the top of the tray, while the other end is fixed to the bottom of the side wall of the cartridge and connected to the inside of the cartridge. During the loading process, the exhaust pipe removes air from the cartridge of the detonator, ensuring that the emulsion explosive completely fills the cartridge of the detonator after loading.

[0030] One-way valve 5 is installed at the end of exhaust pipe 4 located at the top of tray 2, and the outlet end of exhaust pipe 4 is connected to the inlet end of one-way valve 5.

[0031] In this embodiment, the check valve 5 is a straight-through check valve. A straight-through check valve is an automatic valve primarily used to prevent backflow of the medium, ensuring that fluid flows only in one direction. When fluid flows in from the valve inlet, the fluid pressure acts on the valve disc, overcoming its own weight and the spring force, causing the valve disc to open and allowing the fluid to flow smoothly through the valve to the outlet. When the fluid attempts to flow in the opposite direction, the fluid pressure and the valve disc's own weight cause the valve disc to press tightly against the valve seat, thereby cutting off the flow and preventing backflow. This allows the straight-through check valve to play a protective role in hydraulic and pneumatic systems, preventing liquid or gas leakage from the system.

[0032] This invention installs a straight-through one-way valve at the end of the exhaust pipe located at the top of the tray. The outlet end of the exhaust pipe is connected to the inlet end of the one-way valve. During the application of explosives, the air in the explosive spacer cartridge can be discharged, and the emulsion explosive can be prevented from entering the exhaust pipe from the outlet end and blocking the exhaust pipe.

[0033] The tray 2 consists of a top elastic disc 21 and a bottom connector 22, which are bonded together.

[0034] When using the explosive charging device for the detonator spacer, the device is placed in the borehole 1, with the outer edge of the tray 2 fitting against the inner wall of the borehole 1. A cavity is formed between the cartridge 3 and the borehole 1, filled with air 7. During charging, the injection pipe from the explosive mixing vehicle is inserted into the borehole 1, and then emulsion explosive is injected into the cartridge. During the charging process, the vent pipe expels the air 7 from the bottom of the explosive spacer cartridge, ensuring that the emulsion explosive completely fills the explosive spacer cartridge after charging. When the cartridge is about to be filled with emulsion explosive, the injection pipe is slowly withdrawn while injecting the explosive.

[0035] Example 4 A charging device for a detonator spacer includes a tray 2, a cartridge 3, an exhaust pipe 4, and a one-way valve 5. The bottom of the tray 2 is hollow and connected to the top of the cartridge 3. The exhaust pipe 4 passes through the tray 2. One end of the exhaust pipe 4, i.e. the air outlet, is located at the top of the tray 2, and the other end, i.e. the air inlet, is fixed to the bottom of the side wall of the cartridge 3 and connected to the inside of the cartridge 3.

[0036] By installing an exhaust pipe in the detonator, one end of the exhaust pipe passes through the tray and is located at the top of the tray, while the other end is fixed to the bottom of the side wall of the cartridge and connected to the inside of the cartridge. During the charging process, the air in the cartridge of the detonator is discharged through the exhaust pipe, ensuring that the emulsion explosive completely fills the cartridge of the detonator after the charging is completed.

[0037] One-way valve 5 is installed at the end of exhaust pipe 4 located at the top of tray 2, and the outlet end of exhaust pipe 4 is connected to the inlet end of one-way valve 5.

[0038] In this embodiment, the one-way valve 5 is a right-angle one-way valve, and its working principle is the same as that of the straight-through one-way valve. Gas enters from the inlet end, overcomes the spring force and friction to open the right-angle one-way valve port, and flows from the inlet end to the outlet end. When no gas passes through the inlet end, the valve port closes due to the influence of the spring force and the residual force at the outlet end, thus blocking the fluid from the outlet end to the inlet end.

[0039] This invention installs a right-angle one-way valve at the end of the exhaust pipe located at the top of the tray. The outlet end of the exhaust pipe is connected to the inlet end of the one-way valve. During the application of explosives, the air in the explosive spacer cartridge can be discharged, and the emulsion explosive can be prevented from entering the exhaust pipe from the outlet end and blocking the exhaust pipe.

[0040] The tray 2 consists of an elastic disc 21 at the top and a connector 22 at the bottom, which are bonded together. The connector 22 has an internal thread on its bottom inner wall, and the cartridge 3 has an external thread on its top outer wall that mates with the internal thread, thus achieving a threaded connection between the tray 2 and the cartridge 3.

[0041] This utility model consists of a tray, a cartridge, an exhaust pipe, and a one-way valve to form a charging device for a detonating spacer. It has a simple structure and is easy to manufacture. In application, an empty detonating spacer can be placed directly into the borehole 1, and then normal detonation can be carried out, which effectively simplifies the construction process.

[0042] Example 5 A charging device for a detonator spacer includes a tray 2, a cartridge 3, an exhaust pipe 4, and a one-way valve 5. The bottom of the tray 2 is hollow and connected to the top of the cartridge 3. The exhaust pipe 4 passes through the tray 2 and is a flexible venting pipe. One end of the exhaust pipe 4, i.e., the air outlet, is located at the top of the tray 2, and the other end, i.e., the air inlet, is fixed to the bottom of the side wall of the cartridge 3 and connected to the inside of the cartridge 3. The cartridge is made of PVC and has a closed bottom.

[0043] One-way valve 5 is installed at the end of exhaust pipe 4 located at the top of tray 2, and the outlet end of exhaust pipe 4 is connected to the inlet end of one-way valve 5.

[0044] The tray 2 consists of an elastic disc 21 at the top and a connector 22 at the bottom, which are bonded together. The connector 22 has an internal thread on its bottom inner wall, and the cartridge 3 has an external thread on its top outer wall that mates with the internal thread, thus achieving a threaded connection between the tray 2 and the cartridge 3.

[0045] In this embodiment, the one-way valve 5 is a plastic diaphragm one-way valve, which ensures that the fluid can only flow in one direction in the pipeline and effectively prevents backflow.

[0046] This invention installs a plastic diaphragm-type one-way valve at the end of the exhaust pipe located at the top of the tray. The outlet end of the exhaust pipe is connected to the inlet end of the one-way valve. During the application of explosives, the air in the explosive spacer cartridge can be discharged, and the emulsion explosive can be prevented from entering the exhaust pipe from the outlet end and blocking the exhaust pipe.

[0047] When using the explosive charging device for the detonator spacer, the device is placed in the borehole 1, with the outer edge of the tray 2 fitting against the inner wall of the borehole 1. A cavity is formed between the cartridge 3 and the borehole 1, filled with air 7. During charging, the injection pipe from the explosive mixing vehicle is inserted into the borehole 1, and then emulsion explosive is injected into the cartridge. During the charging process, the vent pipe expels the air 7 from the bottom of the explosive spacer cartridge, ensuring that the emulsion explosive completely fills the explosive spacer cartridge after charging. When the cartridge is about to be filled with emulsion explosive, the injection pipe is slowly withdrawn while injecting the explosive.

[0048] Example 6 A charging device for a detonator spacer includes a tray 2, a cartridge 3, an exhaust pipe 4, and a one-way valve 5. The bottom of the tray 2 is hollow and connected to the top of the cartridge 3. The exhaust pipe 4 is a flexible vent pipe that passes through the tray 2. One end of the exhaust pipe 4, i.e., the air outlet, is located at the top of the tray 2, and the other end, i.e., the air inlet, is fixed to the bottom of the side wall of the cartridge 3 and connected to the inside of the cartridge 3. The cartridge is made of PVC and has a closed bottom.

[0049] One-way valve 5 is installed at the end of exhaust pipe 4 located at the top of tray 2, and the outlet end of exhaust pipe 4 is connected to the inlet end of one-way valve 5. One-way valve 5 is a spring-loaded one-way valve. By installing a spring-loaded one-way valve at the end of exhaust pipe located at the top of tray, and connecting the outlet end of exhaust pipe to the inlet end of one-way valve, air 7 in the explosive spacer cartridge can be discharged during the explosive discharge process, and emulsion explosive can be prevented from entering the exhaust pipe from the outlet end of exhaust pipe and blocking the exhaust pipe.

[0050] The tray 2 consists of a top elastic disc 21 and a bottom connector 22, which are bonded together.

[0051] The elastic disc 21 is made of rubber, similar to a plunger. During the loading process, it can fit against the inner wall of the borehole 1 to form an effective seal. Moreover, as the emulsion explosive is driven in, pressure is applied to the elastic disc, making the elastic disc fit more tightly against the inner wall of the borehole 1.

[0052] The connector 22 has an internal thread on its bottom inner wall, and the cartridge 3 has an external thread on its top outer wall that matches the internal thread, so as to realize the threaded connection between the tray 2 and the cartridge 3.

[0053] This invention features an exhaust pipe installed within the detonating spacer. One end of the exhaust pipe passes through a tray at the top, while the other end is fixed to the bottom of the cartridge sidewall, communicating with the inside of the cartridge. During the loading process, the exhaust pipe expels air from the cartridge, ensuring that the emulsion explosive completely fills the detonating spacer cartridge after loading. This invention comprises a tray, cartridge, exhaust pipe, and one-way valve, forming a simple loading device for detonating spacers. It is easy to manufacture and produce. In application, an empty detonating spacer can be directly placed into the borehole before normal explosive loading, effectively simplifying the construction process.
