Description

Technical Field

[0001] The utility model relates to the technical field of emulsion explosive production equipment, in particular to a ground station that uses a triple plunger pump to transport oil-water phases for static emulsification. Background Art

[0002] Emulsion explosives are widely used in mining, tunneling and other fields due to their good stability and safety. Emulsion explosives are made by mixing and emulsifying oil phase, water phase and sensitizer. In the process of emulsification and sensitization, the mixture needs to be mixed at a set temperature and in strict accordance with the proportion to obtain qualified emulsion explosives. If the temperature is too low or too high, or the proportion exceeds the set range, the emulsion explosives will not be mixed successfully, resulting in unqualified products and waste of raw materials.

[0003] The existing ground station uses a rotor delivery pump or a screw pump to deliver materials to the emulsifier and controls the flow rate through a flow meter. When multiple materials need to be delivered at the same time for mixing, multiple delivery pumps and corresponding flow meters are required to work together. Although this structural method can meet the requirements during stable operation, it is often easy to have inconsistent starting speeds of the delivery pumps during the start-up and stop stages, resulting in unstable materials delivered by the delivery pumps during the start-up stage, and the delivered mixed materials seriously deviate from the designed mixing ratio, which results in unqualified emulsion explosives mixed at startup and serious material waste.

[0025] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below, and preferred embodiments of the present invention are given. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0027] Example:

[0028] See also Figure 1-Figure 4The present embodiment provides a ground station for static emulsification of oil-water phase by a triple plunger pump, comprising a first storage tank 71, a second storage tank 72, a third storage tank 73, a static emulsifier 74, a proportional delivery pump 100 with heating and heat preservation, and a pipeline 75; the proportional delivery pump 100 with heating and heat preservation comprises a frame 1, a linear drive mechanism 2, a first pump 3, a second pump 4 and a connecting rod assembly 5, the first pump 3 and the second pump 4 are both mounted on the frame 1, the linear drive mechanism 2 is mounted on the frame 1 and connected to the first pump 3; the connecting rod assembly 5 The first end is hinged on the linear drive mechanism 2, and the second end spans the second pump 4 and is hinged on the frame 1; the telescopic end of the second pump 4 is connected to the connecting rod assembly 5, and the second pump 4 slides along the width direction of the frame 1 and is positioned; it also includes a heating assembly 6, which is arranged around the first pump 3; two second pumps 4 are arranged, and two connecting rod assemblies 5 are also arranged corresponding to the second pumps 4; the first storage tank 71, the second storage tank 72 and the third storage tank 73 are connected through the pipeline 75 to supply materials to the static emulsifier 74 through the first pump 3 and the two second pumps 4 respectively.

[0029] Specifically, the first storage tank 71 is connected to the first pump 3 through the pipeline 75, the second storage tank 72 is connected to one of the second pumps 4 through the pipeline 75, and the third storage tank 73 is connected to the other second pump 4 through the pipeline 75; the static emulsifier 74 is provided with a first inlet 741, a second inlet 742 and a discharge pipe 743, the first pump 3 is connected to the first inlet 741 through the pipeline 75, wherein the second pump 4 connected to the second storage tank 72 is connected to the second inlet 742 through the pipeline 75, and the second pump 4 connected to the third storage tank 73 is connected to the discharge pipe 743 through the pipeline 75.

[0030] It can be known that the first storage tank 71 is used to store water phase materials, the second storage tank 72 is used to store oil phase materials, and the third storage tank 73 is used to store sensitizers. The water phase materials and the oil phase materials are transported to the static emulsifier 74 for mixing and emulsification through the proportional delivery pump 100 with heating and heat preservation, and the emulsified mixture is transported to the collection tank 76 for collection; and when the emulsified mixture is transported to the collection tank 76, the sensitizer stored in the third storage tank 73 is transported by the proportional delivery pump 100 with heating and heat preservation to be mixed with the emulsified mixture in proportion to form explosives, and finally stored in the collection tank 76 for collection. It should be noted that, in the proportional delivery pump 100 with heating and heat preservation, the position of the second pump 4 on the frame 1 can be adjusted along the length direction of the frame 1. When the second pump 4 is adjusted to be close to the first pump 3, the connecting rod assembly 5 drives the second pump 4 to increase its pumping stroke, and the amount of pumped material increases, while the pumping stroke of the first pump 3 remains unchanged, and the amount of pumped material remains unchanged. Therefore, by adjusting the relative position of the second pump 4 on the frame 1, the ratio of the materials pumped by the first pump 3 and the second pump 4 can be adjusted. When the position of the second pump 4 is fixed, the ratio of the materials pumped by the first pump 3 and the second pump 4 is fixed, so that it can pump materials at a stable ratio, so that the mixing ratio of each material in the mixture is always maintained within the set range. The present application adopts a proportional delivery pump 100 with heating and heat preservation for delivery, so that during the delivery process, it can stably deliver according to a fixed ratio, and the delivery ratio of each material remains unchanged during the start and stop process. In addition, the pumped material is heated and insulated by the heating component 6, so that the pumped material is always maintained at the set temperature. Therefore, it can be ensured that qualified mixed emulsion explosives can always be obtained during the production process, the occurrence of unqualified emulsion explosives is reduced, and the waste of materials is greatly reduced.

[0031] Furthermore, the first pump 3 includes a first piston 31, a first rod 32 and a first cylinder 33. The first cylinder 33 is mounted on the frame 1. The first piston 31 is slidably connected in the first cylinder 33. The first piston 31 separates a first rod chamber 331 and a first rodless chamber 332 in the first cylinder 33. The first end of the first rod 32 is connected to the first piston 31, and the second end of the first rod 32 extends out of the first cylinder 33 and is connected to the driving end of the linear drive mechanism 2. 1 is provided with a first one-way valve 311 for controlling the one-way flow of materials from the first rodless chamber 332 to the first rod chamber 331; the first cylinder 33 is provided with a first feed port 333, a first discharge port 334 and a second one-way valve 335, the first feed port 333 is communicated with the first rodless chamber 332, the first discharge port 334 is communicated with the first rod chamber 331, the second one-way valve 335 is arranged on the first cylinder 33, and the second one-way valve 335 is arranged in series with the first feed port 333.

[0032] It can be known that the linear drive mechanism 2 drives the first rod body 32 of the first pump 3 to move, so that the first pump 3 works, and drives the connecting rod assembly 5 through the linear drive mechanism 2 to drive the second pump 4 to work; when the linear drive mechanism 2 drives the first piston 31 and the first rod body 32 downward (moving toward one end of the first rodless chamber 332, so that the volume of the first rodless chamber 332 becomes smaller), the first one-way valve 311 opens, and the second one-way valve 335 is closed, and the material in the first rodless chamber 332 flows from the first rodless chamber 332 to the first rod chamber 331 through the first one-way valve 311. Because of the existence of the first rod body 32, the reduced volume in the first rodless chamber 332 is greater than the increased volume in the first rod chamber 331, thereby increasing the volume in the first rodless chamber 332. The material enters the first rod chamber 331 through the first one-way valve 311, wherein part of the material is stored in the first rod chamber 331, and the other part of the material is discharged through the first discharge port 334, thereby realizing the pumping of the material; when the linear drive mechanism 2 drives the first piston 31 and the first rod body 32 upward (moving toward the end away from the first rodless chamber 332, so that the volume of the first rodless chamber 332 becomes larger), the first one-way valve 311 is closed, the second one-way valve 335 is opened, and the external material is sucked into the first rodless chamber 332 through the first feed port 333, and the material in the first rod chamber 331 is discharged from the first discharge port 334; therefore, when the linear drive mechanism 2 drives the first piston 31 and the first rod body 32 to move, the first pump 3 pumps the material.

[0033] The heating component 6 includes a spacer sleeve 61, on which a first liquid inlet 611 and a first liquid outlet 612 are provided. The spacer sleeve 61 is arranged around the outer periphery of the first cylinder 33, and an annular heating chamber 613 is enclosed between the spacer sleeve 61 and the outer periphery of the first cylinder 33. The first liquid inlet 611 and the first liquid outlet 612 are both connected to the annular heating chamber 613.

[0034] It is worth noting that the liquid used for heating and heat preservation flows from the first liquid inlet 611 into the annular heating chamber 613, and heats the liquid in the first rodless chamber 332 and the first rod chamber 331 by heat conduction, and has a heat preservation function. By setting the heating component 6, the material transported in the first pump 3 is heated and kept warm during the transportation process, preventing the heat loss of the transported material during the transportation process, resulting in the material not achieving an ideal mixing effect during the mixing process.

[0035] The water phase material is transported from the first storage tank 71 to the static emulsifier 74 through the first pump 3, and is input into the static emulsifier 74 from the first inlet 741; the oil phase material is transported from the second storage tank 72 to the static emulsifier 74 through the second pump 4, and is input into the static emulsifier 74 from the second inlet 742; the water phase material and the oil phase material are fully mixed and emulsified in the static emulsifier 74 to obtain a mixture, and the mixture is output from the discharge pipe 743 to be transported toward the collection tank 76; the sensitizer in the third storage tank 73 is transported to the discharge pipe 743 through another second pump 4, and the sensitizer is fully mixed with the mixture in the discharge pipe 743 to form an emulsion explosive, and is stored in the collection tank 76.

[0036] Furthermore, it also includes a crusher 81, a screw conveyor 82, a water phase configuration tank 83 and a water phase intermediate pump 84, the first end of the screw conveyor 82 is connected to the output port of the crusher 81, the second end of the screw conveyor 82 is connected to the water phase configuration tank 83, the crusher 81 is used to crush solid materials, and the crushed solid materials are transported to the water phase configuration tank 83 through the screw conveyor 82 for configuration of water phase materials; the first end of the water phase intermediate pump 84 is connected to the water phase configuration tank 83, the second end of the water phase intermediate pump 84 is connected to the first storage tank 71, and the water phase material configured in the water phase configuration tank 83 is transported to the water phase storage tank through the water phase intermediate pump 84 for storage.

[0037] Furthermore, it also includes an oil phase configuration tank 91 and an oil phase intermediate pump 92. The oil phase configuration tank 91 is used to configure the oil phase material. The first end of the oil phase intermediate pump 92 is connected to the oil phase configuration tank 91, and the second end of the oil phase configuration tank 91 is connected to the second storage tank 72. The oil phase material configured in the oil phase configuration tank 91 is transported to the second storage tank 72 for storage through the oil phase intermediate pump 92.

[0038] Furthermore, a columnar heating chamber 321 is provided inside the first rod body 32 , and a second liquid inlet 322 and a second liquid outlet 323 are provided on the first rod body 32 . Both the second liquid inlet 322 and the second liquid outlet 323 are communicated with the columnar heating chamber 321 .

[0039] It can be known that by inputting the heating liquid from the second liquid inlet 322, the heating liquid is discharged from the second liquid outlet 323 after heat exchange in the columnar heating chamber 321, and the material in the first rod chamber 331 is heated and kept warm by heat conduction through the outer wall of the first rod body 32. Therefore, the material in the first rod chamber 331 is heated and kept warm under the joint action of the heating component 6 and the columnar heating chamber 321 in the first rod body 32, which improves the heating efficiency on the one hand and makes the heating more uniform and thorough on the other hand. It is worth noting that the material pumped by the first pump 3 first enters the rodless chamber through the second one-way valve 335, and is initially heated for the first time under the action of the heating component 6 in the rodless chamber. During the pumping process, the material in the rodless chamber enters the rod chamber through the first one-way valve 311, and the material is heated again in the first rod chamber 331 under the dual action of the heating component 6 and the first rod body 32, and the temperature reaches the design temperature, and is discharged from the first discharge port 334. The material is heated twice during the pumping process by the first pump 3. The heating process is gradual and sufficient. Liquid is used for heating, and the heating process is gentle. It is suitable for heating hazardous chemicals and reduces the heating risk.

[0040] Furthermore, the second liquid inlet 322 and the second liquid outlet 323 are both arranged at the top of the first rod body 32; a liquid distribution tube 324 is provided in the first rod body 32, the first end of the liquid distribution tube 324 is connected to the second liquid outlet 323, and the second end of the liquid distribution tube 324 extends toward the direction close to the bottom of the first rod body 32 to the bottom of the columnar heating chamber 321.

[0041] It can be known that the heating liquid enters the columnar heating chamber 321 from the second liquid inlet 322, and transfers heat to the material in the first rod chamber 331 by heat conduction. The temperature of the heating liquid drops after heat exchange, and is discharged from the liquid distribution pipe 324 at the bottom of the columnar heating chamber 321 through the second liquid outlet 323. The flow direction of the heating liquid is approximately from the top of the first rod body 32 toward the first piston 31, and the flow direction of the material in the first rod chamber 331 is from the first piston 31 toward the first discharge port 334, approximately from the first piston 31 toward the top of the first rod body 32. The material flow direction is opposite to the flow direction of the heating liquid, so that the material to be heated first contacts the first rod body 32 at the lowest temperature of the heating liquid, and as the material continues to flow, the temperature of the first rod body 32 is higher as it is farther away from the first piston 31, so that the first rod body 32 can continuously heat the material. It should be noted that the heating liquid can be a flowing heat storage medium such as hot water and hot oil.

[0042] Further, the flow area of ​​the cross section of the first rodless cavity 332 is equal to twice the flow area of ​​the cross section of the first rod-containing cavity 331 .

[0043] As a result, when the first rod body 32 and the first piston 31 move downward, the volume of the first rodless chamber 332 decreases by twice the volume of the first rod chamber 331. When the first piston 31 and the first rod body 32 move downward, the liquid in the first rodless chamber 332 flows from the first rodless chamber 332 to the first rod chamber 331 through the first one-way valve 311, and half of the liquid is stored in the first rod chamber 331, and the other half of the liquid is discharged from the first liquid outlet 612. When the first piston 31 and the first rod body 32 move upward, the outside The liquid is sucked into the first rodless chamber 332 through the second one-way valve 335, and the liquid in the first rodless chamber 332 is discharged from the first discharge port 334; and the amount of material discharged from the first discharge port 334 is equal to the amount of material discharged when the first piston 31 and the first rod body 32 move upward, that is, when the upward and downward speeds of the first piston 31 and the first rod body 32 are the same, the flow rate of material discharged from the first discharge port 334 is equal, so that the first pump 3 can stably discharge material from the first discharge port 334 when working.

[0044] Furthermore, the first liquid inlet 611 is arranged at one end of the spacer 61 away from the first rod body 32 , and the first liquid outlet 612 is arranged at one end of the spacer 61 close to the first rod body 32 .

[0045] It can be known that the material pumped by the first pump 3 flows from the first rodless cavity 332 to the first rodded cavity 331, and the liquid used for heating and insulation flows from the first liquid inlet 611 into the annular heating cavity 613 and from the annular heating cavity 613 to the first liquid outlet 612. The flow direction is opposite to the flow direction of the material. The temperature of the heated and insulating liquid at the first liquid inlet 611 is high, and the temperature of the heated and insulating liquid at the first liquid outlet 612 is low, so that the material pumped by the first pump 3 flows from the first liquid outlet 612 to the first liquid inlet 611, so that the material can be continuously and stably heated during the transportation process, and the temperature after heating is closer to the temperature of the heating and insulating liquid.

[0046] In this embodiment, the linear drive mechanism 2 is a hydraulic cylinder, which drives the first pump 3 to work by extending or retracting the hydraulic cylinder, and drives the connecting rod assembly 5 to work by extending or retracting the hydraulic cylinder, thereby driving the second pump 4 to work. It should be noted that in some other embodiments of the present application, the linear drive mechanism 2 can also be an electric push rod or a cylinder.

[0047] Furthermore, the connecting rod assembly 5 includes a first connecting rod 51 and a second connecting rod 52, the first end of the first connecting rod 51 is hinged to the driving end of the linear drive mechanism 2, the second end of the first connecting rod 51 is hinged to the first end of the second connecting rod 52, and the second end of the second connecting rod 52 is hinged to the frame 1.

[0048] It can be known that the linear drive mechanism 2 drives one end of the second connecting rod 52 to move, thereby driving the second connecting rod 52 and the first connecting rod 51 to move simultaneously, and the second connecting rod 52 drives the second pump 4 to work during the movement.

[0049] Furthermore, the first one-way valve 311 includes a ball, and a main channel 312 and a branch channel 313 are provided on the first piston 31. The first end of the main channel 312 is connected to the branch channel 313, the second end of the main channel 312 is connected to the first rodless cavity 332, and the end of the branch channel 313 away from the main channel 312 is connected to the first rod cavity 331; the upper end of the main channel 312 is large and the lower end is small, the ball is arranged in the large end of the main channel 312, and the ball abuts against the small end of the main channel 312.

[0050] It can be known that the ball is pressed on the main flow channel 312 under the action of gravity. When the first piston 31 moves downward, the volume of the first rodless chamber 332 decreases and the pressure increases, and the volume of the first rod chamber 331 increases and the pressure decreases. The pressure of the ball near the end of the first rodless chamber 332 is high, and the pressure of the ball near the end of the first rod chamber 331 is low. The ball moves toward one end of the first rod chamber 331, so that the main flow channel 312 is connected to the branch flow channel 313, the first one-way valve 311 is opened, and the material flows from the main flow channel 312 to the branch flow channel 313, thereby allowing the material to flow from the first rodless chamber 332 to the branch flow channel 313. When the first piston 31 moves upward, the volume of the first rodless chamber 332 increases, and the volume of the first rodless chamber 331 decreases. The pressure at one end of the ball close to the first rodless chamber 332 is small, and the pressure at one end of the ball close to the first rodless chamber 331 is large. The ball moves toward one end of the first rodless chamber 332 and abuts against the main channel 312, so that the main channel 312 is disconnected from the branch channel 313, and the first one-way valve 311 is closed, thereby preventing the material from flowing back from the first rod chamber 331 to the first rodless chamber 332 to prevent backflow.

[0051] The first one-way valve 311 also includes an elastic member, which is arranged in the main flow channel 312, one end of the elastic member abuts against the side wall of the main flow channel 312, and the other end of the elastic member abuts against the ball. Through the arrangement of the elastic member, the ball is pressed against the inner wall of the main flow channel 312 to achieve the sealing of the one-way valve, that is, the one-way valve can be kept sealed without the help of the gravity of the ball, so that the direction of the first pump 3 can be arranged vertically or horizontally, increasing the application range of the first pump 3. In this embodiment, the elastic member is a compression coil spring. In some other embodiments of the present application, the elastic member can also be a gas spring, an elastic sheet, a rubber spring or other components or structures that can provide elastic potential energy.

[0052] Further, the second pump 4 includes a second piston 41, a second rod 42, a second cylinder 43 and a slider 44. The second cylinder 43 is mounted on the frame 1. The second piston 41 is slidably connected in the second cylinder 43. The second piston 41 separates a second rod chamber 431 and a second rodless chamber 432 in the second cylinder 43. The first end of the second rod 42 is connected to the second piston 41. The second end of the second rod 42 extends out of the second cylinder 43 and is hinged to the slider 44. The slider 44 is slidably connected to the first connecting rod 5. 1; the second piston 41 is provided with a third one-way valve 411 for controlling the one-way flow of material from the second rodless chamber 432 to the second rod chamber 431; the second cylinder 43 is provided with a second feed port 433, a second discharge port 434 and a fourth one-way valve 435, the second feed port 433 is communicated with the second rodless chamber 432, the second discharge port 434 is communicated with the second rod chamber 431, the fourth one-way valve 435 is arranged on the second cylinder 43, and the fourth one-way valve 435 is arranged in series with the second feed port 433.

[0053] It can be known that the linear drive mechanism 2 drives the first connecting rod 51 and the second connecting rod 52 to swing, and the second connecting rod 52 drives the slider 44 and the second rod body 42 to move, and drives the second piston 41 to reciprocate in the second cylinder 43. When the second piston 41 moves downward, the third one-way valve 411 opens, the fourth one-way valve 435 closes, and the material in the second rodless chamber 432 enters the second rod chamber 431 through the third one-way valve 411 and is discharged through the second discharge port 434. When the second piston 41 moves upward, the third one-way valve 411 closes, the fourth one-way valve 435 opens, and the external material enters the second rodless chamber 432 through the second feed port 433, and the material in the second rod chamber 431 is discharged from the second discharge port 434. As the linear drive mechanism 2 drives the first connecting rod 51 and the second connecting rod 52 to swing continuously, the second rod body 42 and the second piston 41 are driven to move continuously, so that the second pump 4 continues to pump the material. The flow cross-sectional area of ​​the second rodless chamber 432 is equal to twice the flow cross-sectional area of ​​the second rod chamber 431, so that the amount of material discharged by the second piston 41 when descending and ascending is equal, so that the second pump 4 can continuously and stably pump material during operation.

[0054] It should be noted that a heating component 6 is also arranged on the outside of the second pump 4 connected to the second storage tank 72, and the material pumped by the second pump 4 is heated and kept warm by the heating component 6; the second pump 4 connected to the third storage tank 73 is used for pumping the sensitizer and therefore does not need to be heated or kept warm, so there is no need to set a heating component 6 outside the second pump 4 connected to the third storage tank 73.

[0055] It should be noted that the position of the second pump 4 on the frame 1 can be adjusted. The closer the second pump 4 is to the first pump 3, the greater the swing amplitude of the slider 44 and the second piston 41 driven by the second connecting rod 52, and the more material is pumped out by a single reciprocating stroke. By adjusting the position of the second pump 4 on the frame 1, the ratio of the materials pumped out by the first pump 3 and the second pump 4 can be adjusted.

For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
