Description

Technical Field

[0001] This utility model relates to the field of emulsion explosives technology, and in particular to an emulsifier addition device for the production of emulsion explosives. Background Technology

[0002] Emulsion explosives utilize the action of emulsifiers to uniformly disperse microdroplets of oxidizing salt aqueous solutions in a continuous oil-phase medium containing porous materials such as dispersed air bubbles or hollow glass microspheres, forming a water-in-oil emulsion explosive. It has the characteristics of high density, high detonation velocity, high saturation, good water resistance, small critical diameter, and good initiation sensitivity.

[0003] Currently, in the production of emulsion explosives, the addition of emulsifiers is a crucial step in ensuring the formation of a stable latex system between the oil phase (such as mineral oil, wax, etc.) and the aqueous phase (such as ammonium nitrate solution). In existing technologies, to quantitatively add liquid emulsifiers, metering pumps such as gear pumps are generally used to inject the emulsifier into the oil phase pipeline in proportion to mix with the molten oil phase, and then stirring to form a homogeneous emulsion matrix.

[0004] However, when a gear pump is running, the high-speed rotation of its gears (typically 500-1500 rpm) applies high shear force to the fluid, which causes damage to the molecular chains of emulsifiers (such as the polymeric emulsifier polyisobutylene succinimide), reducing its emulsifying activity and affecting the quality of the emulsion matrix.

[0005] Therefore, this application provides an emulsifier addition device for the production of emulsion explosives to solve the above-mentioned technical problems. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide an emulsifier addition device for the production of emulsion explosives, in order to solve the problem in the prior art that when emulsifier is added quantitatively by means of a gear pump or other metering pump, the molecular chain of the emulsifier is easily damaged, the emulsification activity is reduced, and the final quality of the emulsion matrix is ​​affected.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] An emulsifier addition device for the production of emulsion explosives includes a base, an addition cylinder fixed on the base, a feed pipe and an outlet pipe installed at one end of the addition cylinder, and a cylinder fixed at the other end of the addition cylinder, with the cylinder's shaft extending into the addition cylinder and connected to a piston.

[0009] Both the feed pipe and the discharge pipe extend into the base, and a first diaphragm flap is movably connected to the outside of the port of the feed pipe extending into the base. The first diaphragm flap only allows the medium to be output from the port of the feed pipe. A second diaphragm flap is movably connected to the inside of the port of the discharge pipe extending into the base. The second diaphragm flap only allows the medium to be input into the port of the discharge pipe.

[0010] Optionally, the base is symmetrically fixed with fixing ears on both sides of its bottom.

[0011] Optionally, a fixing platform is fixed to the upper end face of the base, and the adding cylinder is fixed to the fixing platform by bolts.

[0012] Optionally, the base has a mounting groove in the middle, and a controller is installed in the mounting groove to control the cylinder to start.

[0013] Optionally, a heating chamber is provided in the inner wall of the adding cylinder, and an electric heating component is provided in the heating chamber.

[0014] Optionally, the upper end face of the adding cylinder is provided with a control component for controlling the electric heating component.

[0015] Optionally, the heating element is a heating wire surrounding the adding cylinder.

[0016] Compared with the prior art, this utility model has at least the following beneficial effects:

[0017] In the above scheme, thanks to the cooperation of the addition cylinder, feed pipe, discharge pipe, cylinder and piston, the emulsifier can be drawn through the feed pipe by the addition cylinder and output through the discharge pipe. With the addition cylinder and piston, the effect of quantitative addition of emulsifier can be achieved. Moreover, compared with the gear pump and other metering pumps in the prior art, this device can avoid damaging the molecular chain of emulsifier while quantitatively adding emulsifier, which helps to ensure the quality of the final emulsion matrix.

[0018] In the above solution, thanks to the cooperation of the addition cylinder, heating chamber, electric heating component and control component, the emulsifier can be kept heated during the quantitative addition of emulsifier, ensuring its melting or liquid fluidity, while avoiding high-temperature decomposition.

[0019] In summary, this device can not only add emulsifiers quantitatively, but also avoid damaging the molecular chains of the emulsifiers, ensuring their activity and thus guaranteeing the quality of the final emulsion matrix. Attached Figure Description

Those skilled in the art can adjust or modify these devices and environments according to specific needs. Detailed Implementation

[0028] The following is a detailed description of an emulsifier addition device for the production of emulsion explosives provided by this utility model, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0029] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0030] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0031] It is understood that the meanings of “on”, “above”, and “above” in this utility model should be interpreted in the broadest manner, such that “on” not only means “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” not only means “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0032] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings. Spatially related terms are intended to cover different orientations in the use or operation of the device other than those depicted in the accompanying drawings. The device may be oriented in other ways, and the spatially related descriptive terms used herein can be interpreted similarly.

[0033] like Figure 1 and Figure 2 As shown, an embodiment of this utility model provides an emulsifier addition device for the production of emulsion explosives, including a base 1. Fixing ears 101 are symmetrically fixed on both sides of the bottom of the base 1, and the fixing ears 101 are used for fixing with bolts. A fixing platform 102 is fixed to the upper surface of the base 1, and an addition cylinder 2 is installed on the fixing platform 102 with bolts. One end of the addition cylinder 2 is equipped with an inlet pipe 3 and an outlet pipe 4, and the other end of the addition cylinder 2 is fixed with a cylinder 5. The shaft of the cylinder 5 extends into the addition cylinder 2 and is connected to a piston 6. An installation groove 103 is provided in the middle of the base 1, and a controller 10 is installed in the installation groove 103. The controller 10 controls the cylinder 5 to start. In specific implementations, the controller 10 can be, but is not limited to, a PLC controller, to control the cylinder 5 to drive the piston 6 to move at a fixed frequency.

[0034] like Figure 3 and Figure 4As shown, both the feed pipe 3 and the discharge pipe 4 extend into the base 1. A first membrane flap 301 is movably connected to the outer side of the port of the feed pipe 3 extending into the base 1. The first membrane flap 301 only allows the medium to exit from the port of the feed pipe 3. A second membrane flap 401 is movably connected to the inner side of the port of the discharge pipe 4 extending into the base 1. The second membrane flap 401 only allows the medium to enter into the port of the discharge pipe 4. Therefore, the addition cylinder 2 can draw emulsifier through the feed pipe 3 and deliver emulsifier outward through the discharge pipe 4. Combined with the metering volume of the addition cylinder 2, a metered addition effect of the emulsifier can be achieved.

[0035] In addition, in this embodiment, a heating chamber 7 is formed in the inner wall of the adding cylinder 2, and an electric heating component 8 is disposed in the heating chamber 7. A control component 9 for controlling the electric heating component 8 is disposed on the upper end face of the adding cylinder 2. In specific implementation, the electric heating component 8 may be, but is not limited to, an electric heating wire surrounding the adding cylinder 2, and the heating temperature of the electric heating component 8 is controlled at 80-95℃.

[0036] The working principle provided by this utility model is that, in use, the emulsifier addition device for emulsion explosive production can be activated by starting the cylinder 5 to drive the piston 6 to move inside the addition cylinder 2, so that the addition cylinder 2 can draw emulsifier through the feed pipe 3 and output it through the discharge pipe 4, achieving the effect of quantitative addition of emulsifier. Moreover, compared with the gear pump and other metering pumps in the prior art, this device can avoid damaging the emulsifier molecular chain while quantitatively adding emulsifier, which is conducive to ensuring the quality of the final emulsion matrix.

[0037] Meanwhile, during the quantitative addition of emulsifier, the electric heating component 8 in the heating chamber 7 can be used for heating to maintain the heating of the emulsifier, ensuring its melting or liquid fluidity, while avoiding high-temperature decomposition.

[0038] In summary, this device can not only add emulsifiers quantitatively, but also avoid damaging the molecular chains of the emulsifiers, ensuring their activity and thus guaranteeing the quality of the final emulsion matrix.

Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
