DETAILED DESCRIPTION

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0035] like Figure 1-Figure 11 As shown, this embodiment provides a water circulation 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, one end of the mud conveying pipe 101 is rotatably connected to a discharge head 105, and the other end of the mud conveying pipe 101 is rotatably connected to a feed head 108, a temperature sensor 104 is installed on the surface of the discharge head 105 and the feed head 108, and a first sealing frame 103 is fixedly connected to the surface 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 cavity 106 .

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

[0039] Furthermore, the water circulation mechanism 200 includes a hot water casing 201 , and the front and rear sides of the top of the hot water casing 201 are connected with a water inlet head 202 and a water outlet head 203 . The front and rear ends of the hot water casing 201 are fixedly sleeved with a mounting frame 206 , and the mounting frame 206 is fixedly installed on the top of the base 107 .

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

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

[0042] Furthermore, the spiral directions of the inner spiral blade 102 and the outer spiral blade 207 are opposite.

[0043] By using the mud conveying mechanism 100 and the water circulation mechanism 200 in coordination, the mud liquid can be heated conveniently. The mud flows forward inside the mud conveying mechanism 100, and the hot water circulates in the reverse direction inside the water circulation mechanism 200. The countercurrent heat exchange method can significantly improve the heat transfer efficiency and help to heat the mud more evenly. The countercurrent design allows the mud to gradually heat up along the entire flow path, rather than heating quickly near the inlet and insufficiently heating 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, and flows inside the heating chamber 106. The mud is first regulated by the flow rate regulating component 500, and then divided and stirred by the dividing ring 400 and the stirring component 600. Finally, the mud is guided by the inner spiral blade 102 to flow in a spiral manner, thereby promoting the mixing of muds of 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 according to the final detection temperature.

[0045] The water circulation mechanism 200 is connected to the circulating water heater, the water outlet end of the circulating water heater is connected to the water inlet head 202, and the water inlet end is connected to the water outlet head 203, so that hot water circulates in the inner cavity of the hot water casing 201. During the circulation process, the hot water contacts the surface of the mud conveying pipe 101 to transfer heat to the mud in the heating chamber 106 to heat the mud.

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

[0047] Furthermore, the driving mechanism 300 includes a gear ring 301 and a fixing seat 304 . The gear ring 301 is fixedly sleeved on the surface of the mud conveying pipe 101 , and the fixing 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 fixing seat 304 , and a rotating rod 306 is rotatably connected to the top of the fixing seat 304 . The surface of the rotating rod 306 is respectively fixedly sleeved with a gear 302 and a driven bevel gear 307 .

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

[0050] By setting up the driving 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 driving mechanism 300, the output shaft of the motor 305 drives the rotating rod 306 and the gear 302 to rotate through the active bevel gear 303 and the driven bevel gear 307, and 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 is driven to rotate to change the heating position of the mud and improve the uniformity of heating. During the rotation of the mud conveying pipe 101, the inner walls of the discharge head 105 and the feed head 108 rotate, and the first sealing frame 103 fixes the discharge head 105 and the feed head 108 to prevent the discharge head 105 and the feed head 108 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 casing 201. During the rotation of the outer spiral blade 207, the hot water inside the hot water casing 201 is spirally conveyed to return the hot water to the discharge head 203.

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

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

[0054] By setting the dividing ring 400, it is convenient to divide the mud in the middle end of the inner cavity of the mud conveying mechanism 100, so as to separate and reorganize the mud fluid and promote the mixing between muds of different temperatures. During the operation of the dividing ring 400, the several honeycomb holes 402 on the ring body 401 divide the mud and divide the mud into several fluids. The mud passing through the honeycomb holes 402 is remixed together, thereby reducing the unevenness on the scale and promoting mixing at the micro level.

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

[0056] Furthermore, the flow rate regulating assembly 500 includes a fixed ring 501, which is fixedly installed on the inner wall of the heating chamber 106, one end of the fixed ring 501 is fixedly connected to a conical bucket 502, the other end of the fixed ring 501 is fixedly connected to an elastic conical sleeve 504, and 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 material.

[0058] Furthermore, a limiting sleeve 505 is fixedly connected to the inner wall of the fixing ring 501, a sliding rod 511 is slidably connected to 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, a plurality of first support members 506 are fixedly connected to one side of the limiting sleeve 505, a plurality of 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, a second connecting rod 508 is rotatably connected to the second support member 509, the second connecting rod 508 is rotatably connected to the opposite end of the first connecting rod 507, and a spring 510 is fixedly connected to the inner sides of the first connecting rod 507 and the second connecting rod 508.

[0059] By setting up the flow rate regulating component 500, it is convenient to block the mud entering the mud conveying mechanism 100, and adjust the entering flow rate of the mud according to the pressure of the entering mud, so that the mud moves slowly inside the mud conveying mechanism 100, thereby improving the heating effect of the mud. During the operation of the flow rate regulating component 500, the pressure head 503 first contacts the entering mud. When the entering pressure of the mud is too large, the pressure head 503 is driven to move. The pressure head 503 drives the elastic conical sleeve 504 to deform and drives the sliding rod 511 to slide. The sliding rod 511 slides inside the limiting sleeve 505, and the limiting sleeve 505 limits the sliding rod 511. During the movement of the sliding rod 511, the second connecting rod 508 is driven to rotate through the second supporting member 509, and the second connecting rod 508 drives the first connecting rod 507 to rotate outward. During the rotation, the spring 510 is compressed synchronously, and the connection between the first connecting rod 507 and the second connecting rod 508 protrudes outward to drive the elastic conical sleeve 504 to deform outward, thereby reducing the gap between the elastic conical sleeve 504 and the heating chamber 106 and reducing the flow rate of the mud. When the pressure of the mud is stable, the spring 510 drives the first connecting rod 507 and the second connecting rod 508 to deform, so that the sliding rod 511 drives the pressure head 503 and the elastic conical sleeve 504 to reset.

[0060] Furthermore, a plurality of stirring assemblies 600 are installed inside the split ring 400 .

[0061] Furthermore, the stirring assembly 600 is installed in the inner cavity of the honeycomb hole 402 in a relative arrangement.

[0062] Furthermore, the stirring assembly 600 includes a stirring frame 601, which is rotatably connected to a mounting rod 602 inside the stirring frame 601. The mounting rod 602 is centrally set or eccentrically set, and the mounting rod 602 is fixedly connected to the inner wall of the honeycomb hole 402. A plurality of inclined grooves 606 are opened on the left and right sides of the stirring frame 601. The inner wall of the inclined groove 606 is rotatably connected to a movable rod 604. The surface of the movable rod 604 is fixedly connected to stirring rods 603 on the front and back sides. The stirring rods 603 are made of elastic metal. The inner wall of the inclined groove 606 is fixedly connected to a limiting block 605, and the limiting block 605 is movably connected to the surface of the movable rod 604 to limit it.

[0063] By setting up the stirring assembly 600, the mud can be further stirred, thereby greatly improving the heating effect of the circulating hot water on the mud, reducing the use of hot water, and reducing energy consumption. In the process of the mud passing through the honeycomb hole 402, the mud impacts the stirring frame 601 to drive the stirring frame 601 to rotate on the surface of the mounting rod 602. During the rotation of the stirring frame 601, a number of movable rods 604 and stirring rods 603 are driven to move synchronously. The movable rod 604 swings up and down inside the inclined groove 606, thereby stirring the mud, further improving the uniformity of mixing between muds of different temperatures.
