Description

Technical Field

[0001] The present invention relates to the field of cooling and energy saving of mud pumps, and particularly to an energy-saving mud pump based on emulsified liquid circulation cooling. Background Art

[0002] The use of emulsified liquid for mud pump cooling is an innovative technology that combines lubrication and heat dissipation, and has important application value especially in high-temperature and high-load industrial scenarios (such as oil drilling, mine exploitation, tunnel construction, etc.); the application of emulsified liquid in mud pump cooling, through the synergistic effect of water-oil two phases, takes into account efficient heat dissipation, and is especially suitable for harsh working conditions. Emulsified liquid is a stable mixture formed by two immiscible liquids through mechanical stirring or the action of chemical emulsifiers; its characteristic is that one of the liquids is evenly dispersed in the other liquid in the form of tiny droplets.

[0003] When the mud pump is running, the heat generated by friction and the conversion of mechanical energy is quickly absorbed by the emulsified liquid, and the heat is taken out of the pump body through the circulation system; the emulsified liquid exchanges heat with the external environment through a heat exchanger or a cooling tower outside the pump, and after completing heat dissipation, it re-enters the pump for circulation, forming a closed-loop cooling system.

[0004] During the process of the emulsified liquid entering the pump for cooling, in order to continuously cool down in a short time, a sufficient amount of emulsified liquid needs to be introduced. Since the contact surface of the cold and heat sources is a crucial factor determining the heat exchange efficiency, it is necessary to fully mobilize the emulsified liquid introduced into the pump so as to expand the contact surface of the cold and heat sources on the basis of sufficient flow; however, the mobility of the emulsified liquid dispersed and mobilized in the pump in the prior art is poor, which affects the contact surface of the cold and heat sources, resulting in a poor cooling effect of the mud pump and causing the mud pump to work with high energy consumption; specifically, for example, the prior art "Mud Pump with Spraying Emulsified Liquid Circulation Recovery and Its Assembly Method (Chinese Patent, Authorization Publication No. CN118088432B)" discloses a "heat exchange pipe" for cooling, and only a "spiral guide rail" is simply arranged inside it, and the "spiral guide rail" cannot disperse and mobilize the emulsified liquid to fully improve the contact surface of the cold and heat sources. Summary of the Invention

[0050] Compared with the prior art, the energy-saving mud pump based on emulsion circulation cooling of the present invention can achieve:

[0051] 1), After the mud pump body generates heat, when the emulsion continuously passes through the inside of the heat exchange tube, it will drive the material stirring frame to rotate. The rotating material stirring frame will continuously push the emulsion at the central position inside the heat exchange tube radially towards the inner wall of the heat exchange tube, so that the emulsion far from the inner wall of the heat exchange tube inside the heat exchange tube is continuously pushed towards the inner wall of the heat exchange tube in turn, realizing the radial stirring of the emulsion to improve the radial fluidity of the emulsion, so as to be beneficial to increasing the contact surface between the emulsion inside the heat exchange tube and the heat source inside the mud pump body, promoting the efficient operation of the mud pump, avoiding excessive energy consumption, and achieving effective energy saving.

[0052] 2) During the process of the emulsion flowing radially towards the inner wall of the heat exchange tube, it will successively pass through the inner dispersion cylinder and the outer dispersion cylinder on the dispersion sleeve group. The inner dispersion cylinder will use multiple dispersion holes and the outer dispersion cylinder will use multiple material guiding holes to disperse the emulsion, which is beneficial to the dispersion fluidity of the emulsion. By fully mobilizing the flow of the emulsion, the contact surface between the cold and heat sources can be increased to complete precise and rapid heat exchange, promote the stable operation of the mud pump body, improve the working efficiency and service life of the mud pump body, avoid excessive energy consumption, and achieve effective energy conservation;

[0053] 3) When the emulsion continuously enters the interior of the heat exchange tube, it will continuously act on the impeller. The impeller drives the driving rotating shaft and multiple material deflecting plates to rotate. The multiple material deflecting plates use the wedge-shaped surface facing the heat exchange tube to continuously push the emulsion at the central position inside the heat exchange tube radially towards the inner wall of the heat exchange tube. After ventilating the cavity two and the airbag, the outward pushing degree of the pushing plate on the wedge-shaped surface can be adjusted, so as to adjust the degree and strength of the outwardly pushed emulsion and promote the cooperation degree with the dispersion sleeve group. At the same time, by periodically charging and discharging the cavity two and the airbag, the pushing plate can be made to outwardly push and inwardly retract periodically on the wedge-shaped surface, realizing that the pushing plate can flexibly provide different degrees and different strengths of thrust on the wedge-shaped surface, which is beneficial to continuously pushing the emulsion at the central position inside the heat exchange tube radially towards the dispersion sleeve group and the heat exchange tube, fully improving the flow of the emulsion and increasing the contact surface between the cold and heat sources;

[0054] 4) After starting the driving motor, the driving motor transmits the power to the outer dispersion cylinder through the driving gear and the driving rack ring, driving the outer dispersion cylinder to rotate. The rotating outer dispersion cylinder forms a continuous dislocation with the inner dispersion cylinder to further disperse the emulsion, which is beneficial to the dispersion fluidity of the emulsion, and the contact surface between the cold and heat sources can be increased by fully mobilizing the flow of the emulsion. Cooperating with the material deflecting rack, the emulsion can be fully and comprehensively dispersed, which is beneficial to increasing the contact surface between the emulsion and the internal heat source of the mud pump body;

[0055] 5) By means of the second air regulating pipe, the air guiding cavity and multiple air guiding pipes, the annular airbag is inflated and deflated. After the annular airbag is inflated and expanded, the aperture of the dispersion hole can be reduced. After the annular airbag is deflated and contracted, the aperture of the dispersion hole can be enlarged, realizing the adjustment of the particle size of the dispersed emulsion;

[0056] 6) The emulsion recycled after absorbing heat is sprayed into the interior of the heat dissipation cylinder through the spray head. The motor is started to drive the dispersion and stirring net plate to rotate. During the process of the dispersion and stirring net plate successively entering the emulsion, the external cold air enters the second air guiding ring structure through the air inlet pipe, and then enters the air inlet duct. The cold air inside the air inlet duct is redistributed and enters multiple air guiding horizontal pipes. On the basis of dispersing the emulsion and preventing it from stratifying, the multiple air guiding horizontal pipes dissipate heat from the emulsion, which is beneficial to the subsequent mud pump for recycling and cooling the emulsion.

DETAILED DESCRIPTION

[0078] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the present invention and are not intended to limit the present invention. The specific implementation of the present invention is described in detail below with reference to the specific embodiments.

[0079] In the embodiment of the present invention, Figures 1 - 3 and Figure 5 As shown: An energy-saving mud pump based on emulsion circulation cooling includes a mud pump body 1, and a heat exchange tube group 2 is installed inside the mud pump body 1. The heat exchange tube group 2 includes:

[0080] Heat exchange tubes are made of heat conductive material;

[0081] The material feeding frame 26 is rotatably mounted on the cylindrical center line of the heat exchange tube. When the emulsion is introduced into the heat exchange tube, the material feeding frame 26 is driven to rotate. The rotating material feeding frame 26 is used to continuously push the emulsion radially toward the inner wall of the heat exchange tube.

[0082] The dispersion sleeve group 27 is inserted into the heat exchange tube and a gap is reserved between the heat exchange tube and the inner wall of the heat exchange tube; the dispersion sleeve group 27 is used to disperse the emulsion passing radially;

[0083] Therefore, in view of the problem that the existing technology has poor fluidity in dispersing and mobilizing the emulsion in the pump, which affects the contact surface of the cold and hot sources, the present application can achieve the following:

[0084] After the mud pump body 1 generates heat, the emulsion continues to flow into the heat exchange tube, which drives the material diverter rack 26 to rotate. The rotating material diverter rack 26 will continuously push the emulsion at the center of the heat exchange tube radially toward the inner wall of the heat exchange tube, so that the emulsion inside the heat exchange tube away from the inner wall of the heat exchange tube is continuously pushed toward the inner wall of the heat exchange tube in turn. By diverting the emulsion in the radial direction, the radial fluidity of the emulsion is improved, so as to increase the contact area between the emulsion inside the heat exchange tube and the internal heat source of the mud pump body 1, avoid excessive energy consumption, and achieve effective energy saving.

[0085] It should be noted that the components of the mud pump body 1 other than the heat exchange tube group 2 that are not described are all prior art, and their detailed structures can be found in existing literature and journals, and they can also be purchased directly on the market, or they can be assembled from components purchased on the market. They are not protected by the present invention and will not be elaborated on in detail here.

[0086] Among them, the dispersion sleeve group 27 includes:

[0087] The outer dispersion cylinder 273 is rotated and inserted into the heat exchange tube. The outer dispersion cylinder 273 is used to disperse the emulsion through the multiple material guide holes provided therein;

[0088] The inner dispersion cylinder 271 is inserted into the outer dispersion cylinder 273 and is independently provided with the outer dispersion cylinder 273. The inner dispersion cylinder 271 is provided with a plurality of dispersion holes 2712 for breaking up the emulsion.

[0089] In the process of the emulsion flowing radially toward the inner wall of the heat exchange tube, it will successively pass through the inner dispersion tube 271 and the outer dispersion tube 273 on the dispersion sleeve group 27. The inner dispersion tube 271 will use multiple dispersion holes 2712 and the outer dispersion tube 273 will use multiple material guide holes to break up the emulsion, which is beneficial to the dispersion fluidity of the emulsion. By fully mobilizing the flow of the emulsion, the contact surface of the cold and heat sources can be increased to complete accurate and rapid heat exchange, promote the stable operation of the mud pump body 1, improve the working efficiency and service life of the mud pump body 1, avoid excessive energy consumption, and achieve effective energy saving.

[0090] In the embodiment of the present invention, Figures 2 - 4 As shown: the material rack 26 includes:

[0091] The driving rotating shaft 262 is rotatably assembled on the material guiding box 265. A first air regulating pipe 22 is fixed on the material guiding box 265. The first air regulating pipe 22 is inserted and fixed on the annular support plate 21 and penetrates through the annular support plate 21. The annular support plate 21 is fixed on the heat exchange pipe.

[0092] A plurality of material pushing plates 263 are all fixed on the driving rotating shaft 262. The plurality of material pushing plates 263 are annularly arrayed around the driving rotating shaft 262. The material pushing plate 263 is provided with a wedge surface on the side facing the heat exchange pipe on its outer side.

[0093] A plurality of material pushing plates 264 correspond to the plurality of material pushing plates 263 one by one. The material pushing plate 264 is movably inserted into a groove formed on the wedge surface of the material pushing plate 263. An airbag is placed inside the groove, and the outer wall of the airbag is connected to the material pushing plate 264.

[0094] An impeller 261 is assembled at the end of the driving rotating shaft 262. The impeller 261 is used to drive the driving rotating shaft 262 and a plurality of material pushing plates 263 to rotate after the emulsion fluid passes through.

[0095] Furthermore, as Figures 2 - 4 shown: A first cavity is formed inside the material guiding box 265, and a second cavity is formed inside the driving rotating shaft 262. The second cavity communicates with the first cavity through a through hole formed in the first cavity by the driving rotating shaft 262. The driving rotating shaft 262 is rotatably connected to the first cavity through a second sealing bearing. The first air regulating pipe 22 communicates with the first cavity. The second cavity communicates with the airbag.

[0096] Therefore, when the emulsion fluid continuously passes into the heat exchange pipe, it will continuously act on the impeller 261. The impeller 261 drives the driving rotating shaft 262 and a plurality of material pushing plates 263 to rotate. The plurality of material pushing plates 263 use the wedge surfaces on the side facing the heat exchange pipe to continuously radially push the emulsion fluid at the central position inside the heat exchange pipe towards the inner wall of the heat exchange pipe. After ventilating the second cavity and the airbag, the outward pushing degree of the material pushing plate 264 on the wedge surface can be adjusted, so as to adjust the degree and strength of the outwardly pushed emulsion fluid and promote the matching degree with the dispersion sleeve group 27. At the same time, by periodically charging and discharging the second cavity and the airbag, the material pushing plate 264 can be periodically outwardly pushed and inwardly retracted on the wedge surface, realizing that the material pushing plate 264 flexibly provides different degrees and different strength thrusts on the wedge surface, which is beneficial to continuously radially pushing the emulsion fluid at the central position inside the heat exchange pipe towards the dispersion sleeve group 27 and the heat exchange pipe, fully improving the flow of the emulsion fluid and increasing the contact surface of the cold and heat sources.

[0097] It should be noted that for the gas flow on the material feeding rack 26: during inflation, the gas first enters the first cavity through the first regulating gas pipe 22, then enters the second cavity, and finally enters the airbag; during deflation, the flow direction is opposite; as for the exhaust fan and the exhaust valve, they both belong to the prior art, and their detailed structures can be obtained from existing literature and periodicals, and can also be directly purchased on the market, or the components can be purchased on the market for assembly, etc.; they are not what the present invention aims to protect, so no detailed description is given here and they are not shown in the drawings.

[0099] an outer dispersion cylinder body;

[0100] a positioning ring 274, sleeved on the outer end of one end of the outer dispersion cylinder body; the positioning ring 274 is rotationally assembled on the inner wall of the heat exchange tube;

[0101] a driving rack ring 272, sleeved on the outer end of the other end of the outer dispersion cylinder body; the driving rack ring 272 is rotationally assembled inside an annular box provided on the heat exchange tube;

[0102] Wherein, a plurality of support plates 276 are fixed between the driving rack ring 272 and the positioning ring 274 and the outer dispersion cylinder body, and the driving rack ring 272 and the positioning ring 274 are supported by the support plates 276 between them and the outer dispersion cylinder body.

[0103] Furthermore, as Figure 2 、 Figure 3 、 Figure 5 and Figure 6 shown: the driving rack ring 272 is power-transmission connected to a driving device; the driving device includes:

[0104] a driving motor 25, assembled at the outer end of the heat exchange tube;

[0105] a driving gear, fixed on the output shaft of the driving motor 25;

[0106] a gear box 24, fixed at the outer end of the heat exchange tube; the driving gear is rotationally assembled inside the gear box 24 and meshes with the driving rack ring 272.

[0107] Therefore, after the driving motor 25 is started, the driving motor 25 transmits power to the outer dispersion cylinder 273 through the driving gear and the driving rack ring 272, driving the outer dispersion cylinder 273 to rotate; the rotating outer dispersion cylinder 273 forms a continuous dislocation with the inner dispersion cylinder 271, so as to further break up the emulsion, which is beneficial to the dispersion fluidity of the emulsion, and achieve an increase in the contact surface of the cold and heat sources by fully mobilizing the flow of the emulsion; combined with the material shifting rack 26, it is possible to fully and comprehensively disperse the emulsion, which is beneficial to increasing the contact surface between the emulsion and the internal heat source of the mud pump body 1.

[0108] In the embodiment of the present invention, as Figure 2 , Figure 3 , Figure 5 and Figure 7 shown: The inner dispersion cylinder 271 includes:

[0109] Inner dispersion cylinder body;

[0111] The second air regulating pipe 23 is installed on the annular material guiding box 275 and communicates with the gas guiding cavity;

[0112] A plurality of air guiding pipes 2711 are all flat and are embedded in the outer wall of the inner dispersion cylinder body; the plurality of air guiding pipes 2711 are annularly arrayed on the inner dispersion cylinder body; the air guiding pipes 2711 communicate with the gas guiding cavity.

[0113] Furthermore, as Figure 7 and Figure 8 shown: An annular airbag 2713 is embedded on the inner wall of the dispersion hole 2712, and the annular airbag 2713 communicates with the air guiding pipe 2711 through an air guiding hole 2714.

[0114] Therefore, through the second air regulating pipe 23, the gas guiding cavity and the plurality of air guiding pipes 2711, air is filled and discharged for the annular airbag 2713. After the annular airbag 2713 is inflated and expanded, the aperture of the dispersion hole 2712 can be reduced. After the annular airbag 2713 deflates and contracts, the aperture of the dispersion hole 2712 can be enlarged, realizing the adjustment of the particle size of the broken emulsion.

[0115] In the embodiment of the present invention, as Figure 1 , Figure 9 and Figure 10As shown: a guide box 3 is installed at the end of one end of the heat exchange tube group 2, and a piston cylinder is installed inside the guide box 3, which is used to mobilize the circulation of the emulsion; a feed pipe 4 is installed at the lower end of the guide box 3, and the feed pipe 4 is installed on the storage box 5; the feed pipe 4 is used to connect the guide box 3 and the storage box 5; an emulsion heat dissipation box 6 is installed inside the storage box 5, and the emulsion heat dissipation box 6 is connected to the feed pipe 4, and the emulsion heat dissipation box 6 includes:

[0116] A heat dissipation cylinder 64 for cooling the emulsion after absorbing heat;

[0117] Two sealing discs 62 are distributed at both ends of the heat dissipation cylinder 64;

[0118] The dispersion rotating frame 61 is rotatably assembled inside the heat dissipation tube 64 .

[0119] Further, such as Figures 10 - 13 As shown: the dispersed rotating frame 61 includes:

[0120] The fixed shaft 612 rotates through the sealing disk 62 and is fixed to the output shaft of the motor;

[0121] The dispersing and shifting mesh plate 611 is fixed to the end of the fixed shaft 612; the dispersing and shifting mesh plate 611 is rotatably assembled on the guide ring structure 1 66 and the guide ring structure 2 67, and the guide ring structure 1 66 and the guide ring structure 2 67 are inserted and fixed on the heat dissipation tube 64;

[0122] Among them, the guide ring structure 1 66 is equipped with an air outlet pipe 65, and the guide ring structure 2 67 is equipped with an air inlet pipe 63. The guide ring structure 1 66 and the guide ring structure 2 67 adopt the same structure; the guide ring structure 1 66 includes an outer sealing ring 661 and an inner guide ring 663, and the inner guide ring 663 is provided with a ring-shaped guide cavity 664 on its outer side wall; the outer sealing ring 661 is rotatably assembled on the inner guide ring 663 outside the guide cavity 664 through a sealing bearing 1 662; the inner guide ring 663 is provided with a guide hole 665.

[0123] In the embodiment of the present invention, Figure 11 and Figure 13 As shown: the dispersed shifting screen 611 includes:

[0124] The rotating shaft 6114 is fixed at the end of the fixed shaft 612;

[0125] The air inlet duct 6111 is inserted and fixed on the rotating shaft 6114; the air inlet duct 6111 is inserted and fixed in the guide hole 665 on the second guide ring structure 67, and is connected to the interior of the second guide ring structure 67;

[0126] The air outlet duct 6113 is inserted and fixed on the rotating shaft 6114; the air outlet duct 6113 and the air inlet duct 6111 are arranged in parallel; the air outlet duct 6113 is inserted and fixed in the material guiding hole 665 of the material guiding ring structure I 66 and communicates with the inside of the material guiding ring structure I 66;

[0127] A plurality of air guiding transverse pipes 6112 are all erected between the air outlet duct 6113 and the air inlet duct 6111; the air guiding transverse pipes 6112 are all communicated with the air outlet duct 6113 and the air inlet duct 6111.

[0128] Therefore, the emulsified liquid recycled after heat absorption is sprayed into the inside of the heat dissipation cylinder 64 through the spray head. The motor is started to drive the dispersion stirring net plate 611 to rotate. During the process that the dispersion stirring net plate 611 successively enters the emulsified liquid, the cold air outside enters the inside of the material guiding ring structure II 67 through the air inlet pipe 63, then enters the air inlet duct 6111. The cold air inside the air inlet duct 6111 is redistributed and enters into a plurality of air guiding transverse pipes 6112, so as to comprehensively and uniformly dissipate heat from the emulsified liquid on the basis of dispersing the emulsified liquid and preventing it from stratifying, which is beneficial to the mud pump for subsequent emulsified liquid recycling and cooling.

[0129] For example, in the prior art "a mud pump for setting up spray emulsified liquid recycling and its assembling method (Chinese patent, the authorized announcement number is CN118088432B)", the "storage tank" used for recycling the emulsified liquid only dissipates heat through its outer wall, so that the heat dissipation effect of the emulsified liquid near the center is very poor, resulting in the problem that the subsequent emulsified liquid continues to be pumped into the mud pump body 1 for cooling with a poor effect.

[0130] In the description of the present invention, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0131] In the description of the present invention, although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
