Detailed Implementation

[0034] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0035] like Figures 1-11 As shown, this embodiment provides a water-circulating mud heating system, including a mud conveying mechanism 100. The mud conveying mechanism 100 includes a mud conveying pipe 101, and the inner cavity of the mud conveying pipe 101 is provided with a heating chamber 106 for conveying mud.

[0036] Furthermore, a discharge head 105 is rotatably connected to one end of the mud conveying pipe 101, and a feed head 108 is rotatably connected to the other end of the mud conveying pipe 101. Temperature sensors 104 are installed on the surfaces of the discharge head 105 and the feed head 108. A first sealing frame 103 is fixedly connected to the surfaces of the discharge head 105 and the feed head 108, and a base 107 is fixedly connected to the bottom of the first sealing frame 103.

[0037] Furthermore, an inner spiral blade 102 is fixedly connected to the rear side of the inner cavity of the heating chamber 106.

[0038] Furthermore, it also includes a water circulation mechanism 200, which is mounted on the surface of the mud conveying mechanism 100 to heat the mud.

[0039] Furthermore, the water circulation mechanism 200 includes a hot water sleeve 201, with an inlet head 202 and an outlet head 203 connected to the front and rear sides of the top of the hot water sleeve 201. Mounting brackets 206 are fixedly fitted at the front and rear ends of the hot water sleeve 201, and the mounting brackets 206 are fixedly installed on the top of the base 107.

[0040] Furthermore, a second sealing frame 204 is fixedly connected to the front and rear ends of the inner cavity of the hot water jacket 201. A rotating ring 205 is rotatably connected to the inner wall of the second sealing frame 204. The rotating ring 205 is fixedly sleeved on the surface of the mud conveying pipe 101. An outer spiral blade 207 is provided in the inner cavity of the hot water jacket 201. The outer spiral blade 207 is fixedly sleeved on the surface of the mud conveying pipe 101.

[0041] Furthermore, the inner walls of the discharge head 105, the feed head 108, and the second sealing frame 204 are all provided with sealing grooves. The front and rear ends of the surface of the mud conveying pipe 101 and the surface of the rotating ring 205 are all provided with sealing protrusions. The sealing protrusions are located in the inner cavity of the sealing groove and are rotatably connected to its inner wall. A rubber sealing ring is fitted on the surface of the sealing protrusion.

[0042] Furthermore, the inner helical blade 102 and the outer helical blade 207 have opposite helical directions.

[0043] The combined use of the mud conveying mechanism 100 and the water circulation mechanism 200 facilitates the heating of the mud slurry. The mud slurry flows forward inside the mud conveying mechanism 100, while the hot water circulates in the opposite direction inside the water circulation mechanism 200. The counter-current heat exchange method can significantly improve the heat transfer efficiency and help to heat the mud more evenly. The counter-current design allows the mud to gradually heat up along the entire flow path, rather than being rapidly heated near the inlet and then insufficiently heated in the subsequent parts. This can avoid the problem of local overheating or insufficient heating and help to achieve a more uniform heating effect.

[0044] During the operation of the mud conveying mechanism 100, the mud enters the mud conveying pipe 101 through the feed head 108. The mud flows inside the heating chamber 106, first being regulated by the flow rate regulating component 500, then divided and agitated by the dividing ring 400 and the stirring component 600, and finally guided by the inner spiral blades 102 to flow in a spiral, promoting the mixing of mud at different temperatures. The heated mud is discharged through the discharge head 105 and enters the subsequent processing equipment. The temperature sensor 104 detects the mud temperature inside the feed head 108 and the discharge head 105 and transmits the detection data to the external controller. The controller controls the outlet water temperature of the circulating water heater based on the final detected temperature.

[0045] The water circulation mechanism 200 is connected to the circulating water heater. The outlet of the circulating water heater is connected to the inlet 202, and the inlet is connected to the outlet 203, so that the hot water circulates in the inner cavity of the hot water sleeve 201. During the circulation process, the hot water comes into contact with the surface of the mud conveying pipe 101 to conduct heat to the mud in the heating chamber 106 and heat the mud.

[0046] Furthermore, it also includes a drive mechanism 300, which is mounted on the surface of the mud conveying mechanism 100 to drive it.

[0047] Furthermore, the drive mechanism 300 includes a gear ring 301 and a fixed seat 304. The gear ring 301 is fixedly sleeved on the surface of the mud conveying pipe 101, and the fixed seat 304 is fixedly installed on the top of the base 107.

[0048] Furthermore, a motor 305 is fixedly connected to the bottom of the fixed base 304, and a rotating rod 306 is rotatably connected to the top of the fixed base 304. A gear 302 and a driven bevel gear 307 are respectively fixedly sleeved on the surface of the rotating rod 306.

[0049] Furthermore, gear 302 meshes with the surface of gear ring 301, and the output shaft of motor 305 is fixedly connected to a driving bevel gear 303, which meshes with the surface of driven bevel gear 307.

[0050] By setting the drive mechanism 300, the mud conveying mechanism 100 can be easily driven, so that it rotates slowly during operation to change the position of the mud and convey hot water. During the operation of the drive mechanism 300, the output shaft of the motor 305 drives the rotating rod 306 and the gear 302 to rotate through the driving bevel gear 303 and the driven bevel gear 307. The gear 302 drives the gear ring 301 and the mud conveying pipe 101 to rotate synchronously, thereby realizing the rotation drive of the mud conveying pipe 101.

[0051] During the rotation of the mud conveying pipe 101, the mud inside the heating chamber 106 rotates, thereby changing the heating position of the mud and improving the uniformity of heating. During the rotation of the mud conveying pipe 101, the inner walls of the discharge head 105 and the inlet head 108 rotate. The first sealing frame 103 fixes the discharge head 105 and the inlet head 108 to prevent them from rotating. The mud conveying pipe 101 also drives the rotating ring 205 to rotate on the inner wall of the second sealing frame 204, and drives the outer spiral blade 207 to rotate in the inner cavity of the hot water jacket 201. During the rotation of the outer spiral blade 207, the hot water inside the hot water jacket 201 is spirally conveyed and returned to the outlet head 203.

[0052] Furthermore, a dividing ring 400 is fixedly installed at the middle of the inner cavity of the mud conveying mechanism 100.

[0053] Furthermore, the dividing ring 400 includes a ring body 401, which is fixedly connected to the middle end of the inner cavity of the heating chamber 106, and the ring body 401 has a plurality of honeycomb holes 402 inside.

[0054] By setting the dividing ring 400, the mud in the middle of the inner cavity of the mud conveying mechanism 100 can be easily divided to separate and recombine the mud fluid, promote the mixing between mud at different temperatures. During the operation of the dividing ring 400, several honeycomb holes 402 on the ring body 401 divide the mud into several fluids. The mud passing through the honeycomb holes 402 is remixed together, thereby reducing the non-uniformity at the scale and promoting the mixing at the micro level.

[0055] Furthermore, a flow rate regulating component 500 is fixedly installed on the front side of the inner cavity of the mud conveying mechanism 100.

[0056] Furthermore, the flow rate regulating component 500 includes a fixing ring 501, which is fixedly installed on the inner wall of the heating chamber 106. One end of the fixing ring 501 is fixedly connected to a conical bucket 502, and the other end of the fixing ring 501 is fixedly connected to an elastic conical sleeve 504. One end of the elastic conical sleeve 504 is fixedly connected to a pressure head 503.

[0057] Furthermore, the elastic conical sleeve 504 is made of rubber.

[0058] Furthermore, a limiting sleeve 505 is fixedly connected to the inner wall of the fixing ring 501, and a sliding rod 511 is slidably connected at the center of the limiting sleeve 505. One end of the sliding rod 511 is fixedly connected to the inner wall of the pressure head 503. Several first support members 506 are fixedly connected to one side of the limiting sleeve 505, and several second support members 509 are fixedly connected to the surface of the sliding rod 511. A first connecting rod 507 is rotatably connected to the first support member 506, and a second connecting rod 508 is rotatably connected to the second support member 509. The opposite ends of the second connecting rod 508 and the first connecting rod 507 are rotatably connected. A spring 510 is fixedly connected to the inner side of the first connecting rod 507 and the second connecting rod 508.

[0059] By setting the flow rate regulating component 500, it is possible to easily block the slurry entering the slurry conveying mechanism 100 and regulate the slurry's inflow rate according to the slurry's pressure, so that the slurry moves slowly inside the slurry conveying mechanism 100, improving the slurry's heating effect. During the operation of the flow rate regulating component 500, the pressure head 503 first contacts the entering slurry. When the slurry's inflow pressure is too high, it drives the pressure head 503 to move. The pressure head 503 causes the elastic conical sleeve 504 to deform and causes the slide rod 511 to slide. The slide rod 511 slides inside the limiting sleeve 505, and the limiting sleeve 505 limits the slide rod 511. During the movement of the slide bar 511, the second support member 509 drives the second connecting rod 508 to rotate, and the second connecting rod 508 drives the first connecting rod 507 to rotate outward. During the rotation, the spring 510 is compressed simultaneously, and the connection between the first connecting rod 507 and the second connecting rod 508 protrudes outward, thereby driving the elastic conical sleeve 504 to deform outward, reducing the gap between the elastic conical sleeve 504 and the heating chamber 106, and reducing the flow speed of the mud. When the pressure of the mud stabilizes, the spring 510 drives the first connecting rod 507 and the second connecting rod 508 to deform, so that the slide bar 511 drives the pressure head 503 and the elastic conical sleeve 504 to reset.

[0060] Furthermore, several agitation components 600 are installed inside the dividing ring 400.

[0061] Furthermore, the agitation component 600 is installed relative to the inner cavity of the honeycomb hole 402.

[0062] Furthermore, the stirring assembly 600 includes a stirring frame 601, with a mounting rod 602 rotatably connected inside the stirring frame 601. The mounting rod 602 is centrally or eccentrically positioned and is fixedly connected to the inner wall of the honeycomb holes 402. Several inclined grooves 606 are provided on the left and right sides of the stirring frame 601. A movable rod 604 is rotatably connected to the inner wall of the inclined groove 606. A stirring rod 603 is fixedly connected to the front and rear sides of the surface of the movable rod 604. The stirring rod 603 is made of elastic metal. A limiting block 605 is fixedly connected to the inner wall of the inclined groove 606. The limiting block 605 is movably connected to the surface of the movable rod 604 to limit its movement.

[0063] By setting up the agitator 600, the mud can be further agitated, thereby greatly improving the heating effect of the circulating hot water on the mud, reducing the amount of hot water used, and reducing energy consumption. As the mud passes through the honeycomb holes 402, it impacts the agitator 601, causing the agitator 601 to rotate on the surface of the mounting rod 602. During the rotation of the agitator 601, it drives several movable rods 604 and agitator rods 603 to move synchronously. The movable rods 604 swing up and down inside the inclined groove 606, thereby agitating the mud and further improving the uniformity of mixing between muds at different temperatures.
