Description

Technical Field

[0001] The invention relates to the field of mud pump cooling and energy saving, and in particular to an energy-saving mud pump based on emulsion circulation cooling. Background Art

[0002] Emulsion for cooling mud pumps is an innovative technology that combines lubrication and heat dissipation, especially in high-temperature, high-load industrial scenarios (such as oil drilling, mining, tunnel construction, etc.). The application of emulsion in cooling mud pumps, through the synergistic effect of water-oil phases, takes into account efficient heat dissipation, and is especially suitable for harsh working conditions. Emulsion is a stable mixture of two immiscible liquids formed by 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 converted from friction and mechanical energy is quickly absorbed by the emulsion, and the heat is carried out of the pump body through the circulation system; the emulsion exchanges heat with the external environment through a heat exchanger or cooling tower outside the pump, and re-enters the pump for circulation after heat dissipation is completed, forming a closed-loop cooling system.

[0004] When the emulsion enters the pump for cooling, a sufficient amount of emulsion needs to be introduced in order to continue cooling in a short period of time. Since the contact surface of the cold and hot sources is a crucial factor in determining the heat exchange efficiency, the emulsion introduced into the pump needs to be fully mobilized so as to expand the contact surface of the cold and hot sources on the basis of full flow. However, the prior art has poor fluidity in the dispersion and mobilization of the emulsion in the pump, which affects the contact surface of the cold and hot sources, causing the cooling effect of the mud pump to deteriorate and causing the mud pump to work with high energy consumption. For example, the prior art "mud pump with spray emulsion circulation recovery and assembly method thereof (Chinese patent, authorization announcement number CN118088432B)" discloses a "heat exchange tube" for cooling, which is simply provided with a "spiral guide rail" inside, and the "spiral guide rail" cannot disperse and mobilize the emulsion so as to fully increase the contact surface of the cold and hot sources. Summary of the invention

[0005] The purpose of the embodiment of the present invention is to provide an energy-saving mud pump based on emulsion circulation cooling, aiming to solve the problem that the contact surface of the cold and heat sources is a crucial factor in determining the heat exchange efficiency. Therefore, the emulsion introduced into the pump needs to be fully mobilized so as to expand the contact surface of the cold and heat sources on the basis of full flow; however, the prior art has poor fluidity in the dispersion and mobilization of the emulsion in the pump, which affects the contact surface of the cold and heat sources, causing the cooling effect of the mud pump to deteriorate and causing the mud pump to work with high energy consumption.

[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, the emulsion will continue to flow into the heat exchange tube, which will drive the material rack to rotate. The rotating material rack 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 pushed toward the inner wall of the heat exchange tube in turn, and the radial fluidity of the emulsion is improved by radially shifting the emulsion, so as to increase the contact surface between the emulsion inside the heat exchange tube and the heat source inside the mud pump body, promote the efficient operation of the mud pump, avoid excessive energy consumption, and achieve effective energy saving;

[0052] 2) When the emulsion flows radially toward the inner wall of the heat exchange tube, it will successively pass through the inner dispersion tube and the outer dispersion tube on the dispersion sleeve group. The inner dispersion tube will use multiple dispersion holes and the outer dispersion tube 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 emulsion flow, the contact surface of the cold and heat sources is increased to complete accurate 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 saving;

[0053] 3) When the emulsion is continuously introduced into the heat exchange tube, it will continuously act on the impeller, which drives the driving shaft and multiple stripper plates to rotate. The multiple stripper plates use the wedge-shaped surface facing the side of the heat exchange tube to continuously push the emulsion at the center of the heat exchange tube radially toward the inner wall of the heat exchange tube. After ventilating the cavity 2 and the airbag, the degree of outward push of the stripper plate on the wedge-shaped surface is adjusted, so as to adjust the degree and strength of the outward push of the emulsion and promote the degree of coordination with the dispersion sleeve group. At the same time, the cavity 2 and the airbag can be periodically inflated and deflated to achieve periodic outward and inward push of the stripper plate on the wedge-shaped surface, so as to achieve flexible provision of different degrees and strengths of thrust on the wedge-shaped surface, which is conducive to the continuous radial push of the emulsion at the center of the heat exchange tube toward the dispersion sleeve group and the heat exchange tube, fully improving the flow of the emulsion and increasing the contact surface of the cold and heat sources.

[0054] 4) After starting the driving motor, the driving motor transmits 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, so as to further break up the emulsion, which is beneficial to the dispersion fluidity of the emulsion, and to increase the contact surface of the cold and heat sources by fully mobilizing the emulsion flow; combined with the material shifting rack, the emulsion can be fully and comprehensively dispersed, which is beneficial to increase the contact surface between the emulsion and the internal heat source of the mud pump body;

[0055] 5) The annular airbag is inflated and deflated through the air-adjusting tube 2, the air-guiding cavity and the multiple air-guiding tubes. After the annular airbag is inflated, 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 expanded, thereby adjusting the particle size of the dispersed emulsion;

[0056] 6) The emulsion recycled after absorbing heat is sprayed into the heat dissipation tube through the spray head, and the motor is started to drive the dispersion and shifting screen to rotate. In the process of the dispersion and shifting screen successively entering the emulsion, the external cold air enters the guide ring structure 2 through the air intake pipe, and then enters the air intake duct. The cold air inside the air intake duct is redistributed into multiple air guide cross pipes, so that the multiple air guide cross pipes can dissipate the heat of the emulsion on the basis of breaking up the emulsion and avoiding its stratification, which is beneficial to the subsequent emulsion recycling and cooling mud pump.

DETAILED DESCRIPTION

[0078] In order to make the purpose, technical scheme and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. The specific implementation of the present invention is described in detail below in conjunction with the specific embodiments.

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

[0080] The heat exchange tube is made of heat-conducting material;

[0081] The material-push rack 26 is rotatably mounted on the column center line inside the heat exchange tube; when the emulsion is introduced into the heat exchange tube, the material-push rack 26 is driven to rotate, and the rotating material-push rack 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 has a gap with 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 the dispersion and mobilization of the emulsion in the pump, which affects the contact surface of the cold and hot sources, the present application can achieve:

[0084] After the mud pump body 1 generates heat, the emulsion continues to flow into the heat exchange tube, which drives the material shifting rack 26 to rotate. The rotating material shifting 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 in 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, and the radial fluidity of the emulsion is improved by shifting the emulsion in the radial direction, so as to increase the contact surface between the emulsion in 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 journals, and can also be purchased directly on the market, or can be assembled from components purchased on the market, etc.; they are not to be protected by the present invention and will not be elaborated on in detail here;

[0086] Wherein, the dispersion sleeve group 27 comprises:

[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 arranged with the outer dispersion cylinder 273; the inner dispersion cylinder 271 is provided with a plurality of dispersion holes 2712, and the dispersion holes 2712 are used to disperse 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 is increased to complete precise 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, Figure 2-Figure 4 As shown: the material shifting frame 26 includes:

[0091] The driving shaft 262 is rotatably mounted on the material guide box 265. The material guide box 265 is fixed with an air conditioning pipe 22. The air conditioning pipe 22 is inserted and fixed on the annular support plate 21 and passes through the annular support plate 21. The annular support plate 21 is fixed on the heat exchange tube.

[0092] A plurality of material-pickup plates 263 are fixed on the driving shaft 262; the plurality of material-pickup plates 263 are distributed in a circular array around the driving shaft 262; the material-pickup plates 263 are provided with a wedge-shaped surface on the outer side thereof facing the heat exchange tube;

[0093] A plurality of push plates 264 are in one-to-one correspondence with a plurality of diverter plates 263; the push plates 264 are movably inserted into the grooves provided on the wedge-shaped surfaces of the diverter plates 263, an air bag is placed inside the grooves, and the outer wall of the air bag is connected to the push plates 264;

[0094] The impeller 261 is mounted at the end of the driving shaft 262 ; the impeller 261 is used to drive the driving shaft 262 and the plurality of material-discharging plates 263 to rotate after the emulsion flows through.

[0096] Therefore, when the emulsion is continuously introduced into the heat exchange tube, it will continuously act on the impeller 261, and the impeller 261 drives the driving shaft 262 and the plurality of stripper plates 263 to rotate. The plurality of stripper plates 263 use the wedge-shaped surface facing the side of the heat exchange tube to continuously radially push the emulsion at the center position of the heat exchange tube to the inner wall of the heat exchange tube. After ventilating the cavity 2 and the airbag, the degree of outward push of the stripper plate 264 on the wedge-shaped surface is adjusted, so as to adjust the degree and strength of the outward push of the emulsion and promote the degree of coordination with the dispersion sleeve group 27. At the same time, the stripper plate 264 can be periodically pushed outward and retracted on the wedge-shaped surface by periodically inflating and deflating the cavity 2 and the airbag, so as to flexibly provide different degrees and strengths of thrust on the wedge-shaped surface, which is conducive to the continuous radial push of the emulsion at the center position of the heat exchange tube to the dispersion sleeve group 27 and the heat exchange tube, fully improving the flow of the emulsion and increasing the contact surface of the cold and heat sources.

[0097] It should be noted that the gas flow on the material dispensing rack 26 is as follows: when inflating, the gas first enters cavity one through the gas regulating pipe 22, then enters cavity two, and finally enters the airbag; when deflated, the flow direction is opposite; as for the exhaust fan and the exhaust valve, they are both prior art, and their detailed structures can be found in existing literature journals, and they can also be purchased directly on the market, or parts can be purchased on the market to assemble them, etc.; they are not what the present invention is intended to protect, and will not be elaborated here, nor drawn in the accompanying drawings.

[0110] An annular material guide box 275 is fixed at the end of the inner dispersion cylinder. An air guide cavity is provided inside the annular material guide box 275. A plurality of dispersion holes 2712 are distributed in an array on the inner dispersion cylinder.

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

[0112] Multiple air guide tubes 2711 are flat and embedded in the outer wall of the inner dispersion cylinder; multiple air guide tubes 2711 are distributed in a circular array on the inner dispersion cylinder; the air guide tubes 2711 are connected to the air guide cavity.

[0113] Further, such as Figure 7 and Figure 8 As shown: an annular air bag 2713 is inlaid on the inner wall of the dispersion hole 2712, and the annular air bag 2713 is connected to the air guide pipe 2711 through the air guide hole 2714.

[0114] Therefore, the annular airbag 2713 can be inflated and deflated by adjusting the air pipe 23, the air guiding cavity and the plurality of air guiding pipes 2711. After the annular airbag 2713 is inflated, the aperture of the dispersion hole 2712 can be reduced. After the annular airbag 2713 is deflated and contracted, the aperture of the dispersion hole 2712 can be expanded, thereby achieving the adjustment of the particle size of the dispersed emulsion.

[0115] In the embodiment of the present invention, Figure 1 , Fig. 9 and Fig.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, and the piston cylinder 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 sink 64 for cooling the emulsion after absorbing heat;

[0117] Two sealing disks 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 cylinder 64 .

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

[0120] A fixed shaft 612 is rotatably inserted through the sealing disk 62 and fixed to the output shaft of the motor;

[0121] The dispersing and moving mesh plate 611 is fixed to the end of the fixed shaft 612; the dispersing and moving mesh plate 611 is rotatably assembled on the material guide ring structure 1 66 and the material guide ring structure 2 67, and the material guide ring structure 1 66 and the material 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, Fig.11 and Fig.13 As shown: the dispersed shifting screen plate 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 inside 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 guide hole 665 of the guide ring structure 66, and is connected to the inside of the guide ring structure 66;

[0127] A plurality of transverse air guide ducts 6112 are all installed between the air outlet duct 6113 and the air inlet duct 6111 ; the transverse air guide ducts 6112 are all connected to the air outlet duct 6113 and the air inlet duct 6111 .

[0128] Therefore, the emulsion recycled after absorbing heat is sprayed into the heat dissipation tube 64 through the spray head, and the motor is started to drive the dispersion and driving mesh plate 611 to rotate. In the process of the dispersion and driving mesh plate 611 entering the emulsion in turn, the external cold air enters the guide ring structure 67 through the air intake pipe 63, and then enters the air inlet duct 6111. The cold air inside the air inlet duct 6111 is redistributed and enters multiple air guide cross pipes 6112. The multiple air guide cross pipes 6112 can disperse the emulsion and avoid its stratification, and comprehensively and evenly dissipate the heat of the emulsion, which is beneficial to the subsequent mud pump for circulating and cooling the emulsion.

[0129] For example, the prior art "mud pump with spray emulsion circulation recovery and assembly method thereof (Chinese patent, authorization announcement number CN118088432B)" discloses that the "storage tank" for recovering the emulsion only dissipates heat from the emulsion through its outer wall. As a result, the heat dissipation effect of the emulsion near the center is very poor, resulting in the problem that the subsequent emulsion continues to be pumped into the interior of the mud pump body 1 for cooling, and the effect becomes poor.

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

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