Description

Technical Field

[0001] This invention relates to the field of quantitative filling equipment technology, specifically to an integrated dual-cylinder piston-type emulsifying vibratory source drug column multi-tube filling machine and its usage method. Background Technology

[0002] The emulsion seismic charge (seismic source bomb) quantitative filling equipment uses a pump or piston cylinder to fill physically sensitized emulsion explosive into a plastic cartridge case, primarily used in seismic exploration. The high energy released during the explosion of the seismic source bomb generates intense vibrations. When these vibration waves propagate through different underground rock strata, they are reflected, refracted, and scattered upon encountering acoustic impedance interfaces. These signals are received by ground-based detectors, and after data processing and analysis, the structure, properties, and hydrocarbon content of the underground rock strata can be inferred.

[0003] The existing hydraulic piston-type 10-tube loading machine uses hydraulic technology to simultaneously fill 10 cartridge cases, making it impossible to independently detect and control the filling amount of each cartridge case;

[0004] The hydraulic piston-type 10-tube loading machine has a split structure, consisting of a hydraulic station, a control cabinet, and the main body of the loading machine. It occupies a large area during installation, the hydraulic pipes are prone to cracking and leaking oil, and it is quite noisy.

[0005] The equipment is not very reliable and requires dedicated operators to supervise and operate it during production, which cannot meet the personnel control requirements of the civil explosives production line (the number of people on the production line cannot exceed 3). Summary of the Invention

[0006] The purpose of this invention is to provide an integrated dual-cylinder piston-type emulsified vibratory source propellant multi-tube loading machine and its usage method, which solves the problems of existing technologies that cannot independently detect and control the filling amount of each cartridge case, occupy a large area during installation, are prone to oil leakage due to hydraulic pipe rupture, have high noise, low equipment reliability, and require multiple dedicated operators to supervise production.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An integrated dual-cylinder piston-type emulsified seismic source charge multi-tube loading machine includes a base, a housing, and a motor. The base is screwed to the ground, and the housing is welded to the right side of the upper surface of the base. The motor is located inside the housing. The machine is characterized by having a cleaning cylinder at the top, a slidably connected explosive dispersion cylinder at the bottom, a dual-cylinder piston connected to the right side of the explosive dispersion cylinder, a servo cylinder connected to the right side of the dual-cylinder piston, a feed valve at the top of the dual-cylinder piston, and several vertically downward-pointing tubular filling heads connected to the bottom of the explosive dispersion cylinder. A filling control valve is located on the outer side of the filling head where it connects to the explosive dispersion cylinder. A guide and cleaning device is located at the bottom of the filling head, with several guide holes corresponding to the filling heads. The guide and cleaning device is driven by the motor inside the housing and slides up and down along a guide shaft on the left outer wall of the housing.

[0009] Several gravity sensors are screwed to the left side of the upper surface of the base. A servo push rod is screwed to the upper part of the gravity sensor. A mold is installed at the top of the servo push rod. Several plastic cartridge cases are provided on the upper part of the mold.

[0010] Furthermore, the filling heads are evenly distributed in a circular array at the bottom of the explosive dispersion cylinder, and each filling head is independently equipped with a filling control valve.

[0011] Furthermore, the servo push rods are evenly distributed in a circular array at the bottom of the mold, and the position of the plastic cartridge case on the upper part of the mold corresponds to the filling head.

[0012] This invention also provides the following technical solutions:

[0013] The integrated dual-cylinder piston-type emulsified vibratory source propellant multi-tube loading machine and its usage method include the following steps:

[0014] S1. The mold containing empty cartridge cases is sent to the loading station via the conveyor line. After the sensor detects that the mold is in place, it automatically locks the mold.

[0015] S2, the guiding and cleaning device positions the empty cartridge case, while the servo push rod extends to push the empty cartridge case to the highest filling position;

[0016] S3. After the empty cartridge case is in place, all filling control valves will open automatically.

[0017] S4. After the filling control valve is fully opened, the dual electric cylinder pistons begin to work, squeezing the explosive into the empty cartridge case.

[0018] S5. As cartridge cases are continuously filled and the weight increases, the servo push rod adjusts the lifting force according to the weight and moves downward.

[0019] S6. Once the filling weight in the cartridge case reaches the set weight, the filling control valve will automatically close.

[0020] S7. After filling is completed, the guide and cleaning device is reset and the filling head nozzle is cleaned. At the same time, the servo push rod returns to the original position to wait for the next filling.

[0021] S8. Mold locking and unlocking, and release the mold to proceed to the next process.

[0022] The beneficial effects of this invention are as follows: This application improves the inherent safety, reliability and operability of the equipment; it can independently detect and control the filling amount of each cartridge case, has a small footprint, a robust structure, low noise, high equipment reliability, and requires less dedicated operators during production.

Ten servo-driven push rod devices are mounted on ten gravity sensors to monitor the weight of the seismic source explosives in real time during operation (the weight changes when the empty cartridge case is filled with different amounts of explosive). Dynamic control precisely applies different lifting forces to ensure consistent density throughout the seismic source explosive loading (ensuring consistent energy release from the explosion). The entire machine is designed as an integrated unit, providing higher control reliability and complying with the safety standards for civil explosive engineering design (GB50089_2018).
