Description

Technical Field

[0001] The invention relates to the technical field of electric heating throttling skids, and in particular to an electric heating throttling skid. Background Art

[0002] The electric heating throttling skid is a special heating equipment designed to meet the production needs of oil fields. During the oil field exploitation process, the gas and liquid produced by the wellhead gas tree often need to be collected and transported at a specific temperature to prevent the formation of hydrates under low temperature conditions. These hydrates may block the pipeline and affect production efficiency and equipment safety. Therefore, the electric heating throttling skid came into being. It integrates multiple functions such as heating, throttling, pressure reduction and temperature control to ensure that the gas and liquid produced at the wellhead can be maintained within a suitable collection and transportation temperature range.

[0003] However, although the electric heating throttling skid plays an important role in oil field production, it still has some inconveniences during use, especially in the aspects of liquid injection control and maintenance of the equipment, the existing technology still has obvious deficiencies.

[0004] In terms of injection control, traditional electric heating throttling skids usually require manual observation of the liquid level line to control the injection progress. This process is not only cumbersome, but also easily affected by human factors, resulting in inaccurate injection volume, which may not only affect the normal operation of the equipment, but also cause waste of resources.

[0005] In terms of maintenance, the existing electric heating throttling skids mostly adopt dry maintenance. This maintenance method requires heating the water temperature of the electric heating furnace to boiling point, then opening the drain valve of the furnace body to quickly drain the hot water in the furnace, and using the residual heat in the machine to dry the metal surface in the machine. Next, the staff needs to tie up the small bag containing desiccant, put it into the furnace through the exhaust port, and hang the small bag with a rope for easy removal. In addition, all valves of the electric heating furnace need to be closed and the exhaust port needs to be sealed with plastic cloth to prevent air from entering the furnace and keep the furnace dry to inhibit metal corrosion. This process is not only complicated to operate, but also requires a lot of manpower and time.

[0006] Whether it is manual control of the injection progress or manual removal and placement of the desiccant, there are problems of low work efficiency and high labor intensity, which not only increases the cost of oil field production, but also may affect the stability and service life of the equipment. Summary of the invention

[0050] An electric heating throttling skid according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0051] like Figure 1-Figure 6 As shown, an electric heating throttling skid according to an embodiment of the present invention includes:

[0052] The skid assembly 1 includes a base 11 and a throttling and decompression manifold assembly 12, a water jacket furnace 13 and an explosion-proof control cabinet 14 which are arranged on the top of the base 11 in sequence in the horizontal direction. Exhaust pipe seats 15 are evenly arranged on the top of the water jacket furnace 13. The water jacket furnace 13 has a coil 16 built in it and is connected to the throttling and decompression manifold assembly 12. A liquid injection pipe seat 17, an electric heater 18 and a sewage pipe seat 19 are arranged on the surface of one end of the water jacket furnace 13 in sequence in the vertical direction.

[0053] The valves in the liquid injection pipe seat 17 and the sewage discharge pipe seat 19 are respectively provided with a first driving gear 171 and a second driving gear 191, and a first one-way transmission is connected between the first driving gear 171 and the valve in the liquid injection pipe seat 17;

[0054] Dry curing and liquid injection joint control assembly 2: includes an electric drive lifting and adjusting mechanism 21, a dry curing cylinder assembly 22 and a liquid injection and sewage discharge joint drive mechanism 23, wherein:

[0055] The electric drive lifting and adjusting mechanism 21 is fixedly connected to the outer end surface of the water jacket furnace 13 and is arranged across the top of the water jacket furnace 13. The dry process curing cylinder assembly 22 is arranged on the electric drive lifting and adjusting mechanism 21 and is connected to the electric drive lifting and adjusting mechanism 21. The liquid injection and sewage discharge joint drive mechanism 23 is arranged on the outer end surface of the water jacket furnace 13 and is respectively connected to the first drive gear 171 and the second drive gear 191. One end of the dry process curing cylinder assembly 22 is respectively connected to multiple groups of exhaust pipe seats 15. The other end of the dry process curing cylinder assembly 22 passes through the bottom of the electric drive lifting and adjusting mechanism 21 and contacts with one end of the liquid injection and sewage discharge joint drive mechanism 23.

[0056] The throttling and pressure reducing manifold assembly 12, the electric heater 18 and the electric drive lifting and adjusting mechanism 21 are respectively connected to the explosion-proof control cabinet 14 through a bus system to realize data transmission and reception of control instructions.

[0057] It should be noted that the water jacket furnace 13 described in this embodiment is equipped with a pressure detection instrument (not shown in the figure).

[0058] It should be noted that the electric heater 18 described in this embodiment is equipped with a temperature control module (not shown in the figure).

[0059] It should be noted that the first one-way transmission described in this embodiment is a ratchet one-way transmission.

[0060] It can be understood that the electric heater 18 is used to heat the liquid in the water jacket furnace 13, and uses the principle of heat conduction to heat the gas and liquid transported to the coil 16, and the throttling and pressure reducing manifold assembly 12 is used to throttle and reduce the pressure of the heated gas and liquid.

[0061] It is understandable that the explosion-proof control cabinet 14 is equipped with a timing unit.

[0062] Specifically, the present invention has an excellent structural design and can accurately follow the standard operating procedures to realize automated liquid injection operations and automatic removal and placement of desiccant. This design not only facilitates the centralized control of the overall system, but also ensures the continuous and stable operation of the equipment, effectively extending the service life of the equipment. By integrating the functions of automatic liquid injection and automatic removal and placement of desiccant, the present invention can largely replace manual operations and significantly reduce labor costs. While greatly improving work efficiency, it also greatly reduces the labor intensity of operators and demonstrates excellent use effects. The present invention is provided with an electric-driven lifting and adjustment mechanism 21, which is a complex system integrating high-precision lifting and angle adjustment functions. The system can not only accurately drive the cylindrical barrel 221 to achieve lifting and adjustment, but also automatically and accurately adjust its angle when the cylindrical barrel 221 reaches a preset height, thereby synchronously adjusting the positions of the blocking cylinder 223, the dehumidification hole column 224 and the drive rod 225, to achieve fast and stable switching operations, with simple overall operation, strong practicality and good use effects. The present invention innovatively introduces the dry curing barrel assembly 22 This component successfully replaces the traditional method of taking and placing bagged desiccant. By flexibly switching the positions of the blocking cylinder 223 and the dehumidification hole column 224, the blocking of the exhaust pipe seat 15 and the normal taking and placing of the desiccant can be easily achieved. The outer layer of the cylindrical barrel 221 is covered with a high-efficiency heat-absorbing coating, which can effectively absorb heat and dehumidify the internal granular desiccant. At the same time, the built-in stirring rack 222 can work synchronously when the barrel rotates to ensure that the desiccant particles are evenly heated and maintain the best dry state, thereby eliminating the trouble of frequently replacing the desiccant and simplifying subsequent operations. It greatly saves manpower and material resources. This design not only improves work efficiency, but also shows excellent use effect. The present invention cleverly designs a liquid injection and sewage discharge joint drive mechanism 23. The core driving force of this mechanism comes from the driving rod 225. Once started, it can accurately control the opening and closing of the valves in the liquid injection pipe seat 17 and the sewage discharge pipe seat 19 according to the preset operating process. This mechanism ensures the smooth realization of automatic liquid injection and automatic sewage discharge functions. It is not only simple to operate and easy to control, but also significantly improves work efficiency and greatly reduces the labor intensity of operators.

[0063] When in use, the liquid injection operation is performed first, and the electric drive lifting and adjusting mechanism 21 operates according to the command. The operation of the electric drive lifting and adjusting mechanism 21 first drives the dry method curing cylinder assembly 22 to vertically descend, so that the blocking cylinder 223 on the dry method curing cylinder assembly 22 is aligned with the exhaust pipe seat 15 and inserted into the exhaust pipe seat 15, thereby blocking the exhaust pipe seat 15. The descent of the dry method curing cylinder assembly 22 synchronously drives the driving rod 225 to descend. When the blocking cylinder 223 blocks the exhaust pipe seat 15, the driving rod 225 descends to trigger the operation of the liquid injection and sewage discharge joint drive mechanism 23. The operation of the liquid injection and sewage discharge joint drive mechanism 23 first drives the first driving gear 171 to rotate, thereby making the valve in the liquid injection pipe seat 17 Open to allow liquid to be injected into the water jacket furnace 13. When the valve is opened, the electric-driven lifting and adjusting mechanism 21 stops running, and the total amount of liquid injection is controlled by controlling the valve opening time. When the set injection time is reached, the electric-driven lifting and adjusting mechanism 21 continues to run, and the injection and sewage discharge driving mechanism 23 continues to run. The operation of the injection and sewage discharge driving mechanism 23 continues to drive the first driving gear 171 to rotate, thereby driving the valve in the injection pipe seat 17 to close, and separate from the first driving gear 171 after the valve is closed. After the injection and sewage discharge driving mechanism 23 is separated from the first driving gear 171, the electric-driven lifting and adjusting mechanism 21 stops running, and the above completes the automatic injection operation.

[0064] When maintenance is required, the liquid in the water jacket furnace 13 is first heated to the set temperature, and then the electric drive lifting and adjusting mechanism 21 operates according to the command, the electric drive lifting and adjusting mechanism 21 operates the linkage driving rod 225 to continue to descend, and triggers the injection and sewage discharge linkage driving mechanism 23 to continue to operate, and the injection and sewage discharge linkage driving mechanism 23 drives the second driving gear 191 to rotate, thereby driving the valve in the sewage pipe seat 19 to open, and realizing automatic sewage discharge operation. When the valve is opened, the electric drive lifting and adjusting mechanism 21 stops running, and the total amount of liquid discharge is controlled by controlling the valve opening time. When the set liquid discharge time is reached, the electric drive lifting and adjusting mechanism 21 continues to operate, and drives the driving rod 225 to rise and reset, driving The moving rod 225 rises and the liquid injection and sewage discharge driving mechanism 23 is operated. The operation of the liquid injection and sewage discharge driving mechanism 23 drives the second driving gear 191 to rotate, thereby driving the valve in the sewage pipe seat 19 to close, and separates from the second driving gear 191 after the valve is closed. After the valve in the sewage pipe seat 19 is closed, the driving rod 225 continues to rise driven by the electric drive lifting and adjusting mechanism 21. Since a first one-way transmission is connected between the first driving gear 171 and the valve in the liquid injection pipe seat 17, during the rising process of the driving rod 225, the liquid injection and sewage discharge driving mechanism 23 will not drive the valve in the liquid injection pipe seat 17 to open and close, thereby maintaining stable liquid injection operation and good use effect.

[0065] After the sewage discharge is completed, dry maintenance operation is required. The electric drive lifting and adjusting mechanism 21 continues to operate and drives the dry process maintenance cylinder assembly 22 to rise vertically. The rise of the dry process maintenance cylinder assembly 22 simultaneously drives the blocking cylinder 223 to rise and separate from the exhaust pipe seat 15. When the dry process maintenance cylinder assembly 22 rises to the set height, the electric drive lifting and adjusting mechanism 21 automatically adjusts the angle of the dry process maintenance cylinder assembly 22 so that the dehumidification hole column 224 is aligned with the position of the exhaust pipe seat 15. Then the electric drive lifting and adjusting mechanism 21 drives the dehumidification hole column 224 to descend vertically and insert it into the exhaust pipe seat 15 to perform the dehumidification operation. Since the driving rod 225 only corresponds to the position of the blocking cylinder 223, when the dehumidification hole column 224 is inserted into the exhaust pipe seat 15, the liquid injection and sewage discharge joint drive mechanism 23 has no power source to drive it, and it is impossible to realize automatic liquid injection and automatic sewage discharge operations, thereby ensuring a stable operation process and good use effect.

[0066] In one embodiment of the present invention, Figure 2 As shown, the electric drive lifting adjustment mechanism 21 includes a door frame 211, a dual-axis motor 212, an encoder 213, a transmission shaft 214, a first bevel gear 215, a reciprocating screw 216, a second bevel gear 217, a lifting slide 218 and a column self-switching mechanism 219, wherein:

[0067] The gantry frame 211 is fixedly connected to the outer end surface of the water jacket furnace 13 and is arranged across the top of the water jacket furnace 13. The dual-axis motor 212 is fixedly connected to the top of the gantry frame 211. The encoder 213 is fixedly connected to the surface of the dual-axis motor 212. The dual-axis motor 212 and the encoder 213 are respectively connected to the explosion-proof control cabinet 14 through the bus system to realize data transmission and control command reception. The transmission shaft 214 is symmetrically connected to the top of the gantry frame 211 and is located on the outside of the dual-axis motor 212. One end of the transmission shaft 214 is fixedly connected to the output end of the dual-axis motor 212, and the other end of the transmission shaft 214 is fixedly connected to the first bevel gear 215. The reciprocating screw 216 rotates symmetrically vertically. It is connected to the inner wall of the portal frame 211, one end of the reciprocating screw rod 216 passes through the top of the portal frame 211 and is fixedly connected to the second bevel gear 217. The second bevel gear 217 corresponds to the first bevel gear 215 and meshes with each other. The lifting slide 218 is threadedly connected to the outer surface of the reciprocating screw rod 216 and is vertically slidably connected to the inner wall of the portal frame 211. The column self-switching mechanism 219 is arranged on the top of the lifting slide 218 and is in contact with the inner wall of the portal frame 211. The surface of the lifting slide 218 is rotatably connected to a connecting seat 2181 and is connected to the column self-switching mechanism 219. The dry curing cylinder assembly 22 is fixedly connected to the connecting seat 2181 by bolts.

[0068] Specifically, the structure and connection relationship of the electric-driven lifting and adjusting mechanism 21 are further explained. The electric-driven lifting and adjusting mechanism 21 is a complex system that integrates high-precision lifting and angle adjustment functions. The system can not only accurately drive the cylindrical barrel 221 to achieve lifting and adjustment, but also automatically and accurately adjust the angle of the cylindrical barrel 221 when it reaches a preset height, thereby synchronously adjusting the positions of the sealing cylinder 223, the dehumidification hole column 224 and the driving rod 225 to achieve fast and stable switching operations. The overall operation is simple, the practicability is strong and the use effect is good.

[0069] Specifically, the electric drive lifting and adjusting mechanism 21 is mainly composed of core components such as a portal frame 211, a dual-axis motor 212, an encoder 213, a transmission shaft 214, a first bevel gear 215, a reciprocating screw 216, a second bevel gear 217, a lifting slide 218 and a column self-switching mechanism 219. These components are precisely designed and connected to jointly realize the lifting and automatic position adjustment functions of the mechanism. Among them, the portal frame 211 serves as the supporting structure of the entire mechanism. The portal frame 211 is fixedly connected to the outer end surface of the water jacket furnace 13 and is arranged across the top of the water jacket furnace 13, providing a stable installation foundation for other components. The dual-axis motor 212 is fixedly connected to the top of the portal frame 211 and is connected to the explosion-proof control cabinet 14 through a bus system to receive control instructions and drive the transmission shaft 214 to rotate. The encoder 213 is used to monitor the speed and position of the dual-axis motor 212 to ensure the accuracy of the lifting and adjusting. The transmission shaft 214 is symmetrically connected to the top of the portal frame 211, and one end is connected to the explosion-proof control cabinet 14. The output end of the dual-axis motor 212 is fixedly connected, and the other end transmits power to the reciprocating screw 216 through the meshing of the first bevel gear 215 and the second bevel gear 217. The reciprocating screw 216 is symmetrically rotated vertically and connected to the inner wall of the door frame 211. The lifting slide 218 is threadedly connected to the outer surface of the reciprocating screw 216. As the reciprocating screw 216 rotates, the lifting slide 218 performs lifting movement in the vertical direction. The lifting movement of the lifting slide 218 synchronously drives the dryer through the connecting seat 2181 The maintenance cylinder assembly 22 is adjusted to achieve lifting and lowering. The column self-switching mechanism 219 is arranged on the top of the lifting slide 218 and is connected to the inner wall of the portal frame 211. The column self-switching mechanism 219 includes a series of complex mechanical structures, which are used to contact the inner wall of the portal frame 211 when the lifting slide 218 reaches the set height, thereby being passively triggered and synchronously adjusting the angle of the cylindrical cylinder 221, thereby synchronously and automatically adjusting the positions of the sealing cylinder 223, the dehumidification hole column 224 and the driving rod 225.

[0070] In one embodiment of the present invention, Figure 3As shown, the column self-switching mechanism 219 includes an outer cylinder 2191, an inner cylinder 2192, a pressure rod 2193, a convex shaft 2194, a spiral guide groove 2195, a first spring 2196, a second one-way transmission 2197, a worm 2198 and a worm wheel 2199, wherein:

[0071] The outer cylinder 2191 is fixedly connected to the top of the lifting slide 218, the inner cylinder 2192 is rotatably connected to the inner wall of the outer cylinder 2191, the pressure rod 2193 is vertically slidably connected to the inner wall of the inner cylinder 2192, one end of the pressure rod 2193 is located inside the inner cylinder 2192 and is fixedly connected to the convex shaft 2194, a spiral guide groove 2195 is opened at the surface of the inner cylinder 2192 corresponding to the position of the convex shaft 2194, one end of the convex shaft 2194 is located inside the spiral guide groove 2195 and is slidably connected to the spiral guide groove 2195 The inner wall, the other end of the pressure rod 2193 passes through the top of the outer cylinder 2191, and is fixedly connected to the top of the outer cylinder 2191 by a first spring 2196, the worm 2198 is rotatably connected to the inner wall of the lifting slide 218, and is connected to the bottom of the inner cylinder 2192 through a second one-way transmission 2197, one end of the connecting seat 2181 passes through the interior of the lifting slide 218, and is fixedly connected to a worm gear 2199, the worm gear 2199 is located on one side of the worm 2198, and is meshed with the worm 2198.

[0072] It should be noted that the second one-way transmission 2197 described in this embodiment is a ratchet one-way transmission.

[0073] Specifically, the structure and connection relationship of the column self-switching mechanism 219 are further explained. The column self-switching mechanism 219 is used to automatically adjust the angle when the cylindrical barrel 221 reaches the set height, thereby synchronously changing the positions of the sealing cylinder 223, the dehumidification hole column 224 and the driving rod 225 to realize automatic switching operation.

[0074] Specifically, the rise of the lifting slide 218 synchronously drives the column self-switching mechanism 219 to rise. When the pressure rod 2193 abuts against the inner wall of the portal frame 211, the pressure rod 2193 moves downward under the influence of the squeezing force of the inner wall of the portal frame 211 and compresses the first spring 2196. The downward movement of the pressure rod 2193 synchronously drives the convex shaft 2194 to move downward along the inner wall of the spiral guide groove 2195, and synchronously drives the inner cylinder 2192 to rotate. The rotation of the inner cylinder 2192 synchronously drives the worm 2198 to rotate through the second one-way transmission 2197. The rotation of the worm 2198 synchronously drives the worm wheel 2199 to rotate. The rotation of the worm wheel 2199 synchronously drives the connecting seat 2181 to rotate. The rotation of the connecting seat 2181 synchronously drives the cylindrical barrel 221 to rotate 90°. The rotation of the cylindrical barrel 221 synchronously drives the sealing cylinder 223, the dehumidification hole column 224 and the driving rod 225 to rotate 90°, thereby realizing automatic position switching and achieving good use effect.

[0075] Since the second one-way transmission device 2197 is a one-way transmission, when the pressure rod 2193 is separated from the inner wall of the portal frame 211, the rotation of the inner cylinder 2192 will not synchronously drive the worm 2198 to rotate through the second one-way transmission device 2197. By utilizing the self-locking property between the worm wheel 2199 and the worm 2198, the angle of the cylindrical barrel 221 can be ensured to remain unchanged, and the use effect is good.

[0076] In one embodiment of the present invention, Figure 4 As shown, the dry curing cylinder assembly 22 includes a cylindrical cylinder 221, a stirring frame 222, a blocking cylinder 223, a moisture removal hole column 224 and a driving rod 225, wherein:

[0077] The cylindrical body 221 is arranged on one side of the top of the exhaust pipe seat 15, and the two ends of the cylindrical body 221 are respectively fixedly connected to the two groups of connecting seats 2181 by bolts, and the stirring frame 222 is fixedly connected to the inner wall of the cylindrical body 221, and the sealing cylinder 223 and the dehumidification hole column 224 are respectively arranged on the surface of the cylindrical body 221 and correspond to the position of the exhaust pipe seat 15. The surface of the dehumidification hole column 224 is evenly provided with through holes, and the dehumidification hole column 224 is connected with the inside of the cylindrical body 221. One end of the sealing cylinder 223 and the dehumidification hole column 224 are respectively slidably connected to the inner wall of the exhaust pipe seat 15, and the driving rod 225 is arranged on the central axis of the cylindrical body 221 close to one end surface of the liquid injection and sewage discharge joint drive mechanism 23, and corresponds to the position of the sealing cylinder 223. One end of the driving rod 225 passes through the bottom of the door-type frame 211 and contacts with one end of the liquid injection and sewage discharge joint drive mechanism 23.

[0078] It should be noted that the cylindrical barrel 221 described in this embodiment stores granular desiccant inside.

[0079] It should also be noted that the outer surface of the cylindrical barrel 221 described in this embodiment is coated with a heat-absorbing coating.

[0080] Specifically, the structure and connection relationship of the dry-process curing cylinder assembly 22 are further explained. The dry-process curing cylinder assembly 22 successfully replaces the traditional method of taking and placing bagged desiccant. By flexibly switching the positions of the sealing cylinder 223 and the dehumidification hole column 224, the exhaust pipe seat 15 can be easily sealed and the desiccant can be normally taken and placed. The outer layer of the cylindrical cylinder 221 is covered with a high-efficiency heat-absorbing coating, which can effectively absorb heat and dehumidify the internal granular desiccant. At the same time, the built-in stirring rack 222 can work synchronously when the cylinder rotates to ensure that the desiccant particles are evenly heated and maintain the best dry state, thereby eliminating the trouble of frequent replacement of desiccant, simplifying subsequent operations, and greatly saving manpower and material resources. This design not only improves work efficiency, but also shows excellent use effect.

[0081] When in use, the rotation of the connecting seat 2181 synchronously drives the cylindrical barrel 221 to rotate, and the rotation of the cylindrical barrel 221 synchronously drives the sealing cylinder 223, the moisture removal hole column 224 and the driving rod 225 to rotate, thereby realizing automatic position switching. Among them, the rotation of the cylindrical barrel 221 also synchronously drives the stirring frame 222 to move, and the stirring frame 222 synchronously stirs the granular desiccant inside the cylindrical barrel 221 during the movement, thereby further improving its degree of dryness, and the use effect is good.

[0082] In one embodiment of the present invention, Figure 4 As shown, the number of the blocking cylinders 223 and the dehumidification hole columns 224 corresponding to the position of the single group of exhaust pipe seats 15 is respectively set to two groups, and the two groups of blocking cylinders 223 and the two groups of dehumidification hole columns 224 are alternately arranged around the surface of the cylindrical barrel 221, wherein the angles between the two groups of blocking cylinders 223 and the two groups of dehumidification hole columns 224 are 180° respectively, and the angle between the blocking cylinder 223 and its adjacent dehumidification hole column 224 is 90°;

[0083] The number of driving rods 225 is set to two groups, and the positions of the driving rods 225 correspond to the positions of the blocking cylinders 223;

[0084] The single rotation angle of the connecting seat 2181 is 90°.

[0085] Specifically, by precisely limiting the number of sealing cylinders 223, moisture-draining hole columns 224 and driving rods 225 and their installation angles, the aim is to make these components perfectly fit the single rotation angle of the connecting seat 2181. This design ensures the position fixity of the components after angle adjustment, thereby improving the stability and use effect of the entire system.

[0086] In one embodiment of the present invention, Figure 5 As shown, the inner wall of the dehumidification hole column 224 is limitedly slidably connected with a conical plugging seat 2241, the conical portion of the conical plugging seat 2241 is arranged toward the cylindrical barrel 221, and the shape of the conical plugging seat 2241 is adapted to the internal space size of the dehumidification hole column 224.

[0087] Specifically, the dehumidification hole column 224, as a key component of the cylindrical barrel 221, has a unique design that greatly enhances the functionality and practicality of the entire system. Inside the dehumidification hole column 224, we cleverly installed a freely slidable conical plug seat 2241. The design of this conical plug seat 2241 is particularly exquisite, and its conical part faces the cylindrical barrel 221. Such a layout plays a vital role when the dehumidification hole column 224 enters the exhaust pipe seat 15. When the dehumidification hole column 224 penetrates into the exhaust pipe seat 15, the conical plug seat 2241 naturally slides down under the traction of gravity. This action cleverly opens the channel, so that the granular desiccant inside the cylindrical barrel 221 can smoothly flow into the dehumidification hole column 224, and the inside of the barrel is effectively dried. More cleverly, Yes, the conical head design of the conical plugging seat 2241 also makes it easy to push the desiccant inside the desiccant hole column 224 back into the cylindrical body 221 when switching the position of the desiccant hole column 224. In addition, the cylindrical end of the conical plugging seat 2241 is cleverly arranged on the side away from the cylindrical body 221. When the conical plugging seat 2241 is in a vertical state, its cylindrical end can tightly seal the desiccant hole column 224 to form an effective barrier to prevent external air from entering the cylindrical body 221 through the desiccant hole column 224 at the top of the cylindrical body 221, thereby keeping the inside of the cylinder dry and clean. The desiccant hole column 224 and the conical plugging seat 2241 inside it are exquisitely designed and powerfully functional, which not only improves the drying efficiency and service life of the entire system, but also greatly reduces the operating difficulty and maintenance cost.

[0088] In one embodiment of the present invention, Figure 5 As shown, the surface of the sealing cylinder 223 and the surface of the moisture discharge hole column 224 are respectively provided with a bowl-shaped sealing ring 2242 , and the bowl mouth of the bowl-shaped sealing ring 2242 is oriented in the same direction as the conical portion of the conical plugging seat 2241 .

[0089] Specifically, a bowl-shaped sealing ring 2242 is provided, and the bowl mouth of the bowl-shaped sealing ring 2242 is oriented in the same direction as the conical portion of the conical plugging seat 2241. This design can improve the sealing performance between the sealing cylinder 223 and the dehumidification hole column 224 and the inner wall of the exhaust pipe seat 15, prevent air from entering, and ensure that the furnace is dry to inhibit metal corrosion.

[0090] In one embodiment of the present invention, Figure 6 As shown, the liquid injection and sewage discharge joint drive mechanism 23 includes a first vertical rod 231, a second spring 232, a first gear rod 233, a second vertical rod 234, a third spring 235 and a second gear rod 236, wherein:

[0091] The first vertical rod body 231 is vertically slidably connected to the outer end surface of the water jacket furnace 13, and a second spring 232 is fixedly connected to the outer end surface of the water jacket furnace 13, the first gear rod 233 is vertically slidably connected to the outer end surface of the water jacket furnace 13, and is fixedly connected to the top of the first vertical rod body 231, the first gear rod 233 is located on one side of the first driving gear 171, and is meshed with the first driving gear 171, the second vertical rod body 234 is vertically slidably connected to the outer end surface of the water jacket furnace 13, and a third spring 235 is fixedly connected to the outer end surface of the water jacket furnace 13, the second gear rod 236 is vertically slidably connected to the outer end surface of the water jacket furnace 13, and is fixedly connected to the bottom of the second vertical rod body 234, the second gear rod 236 is located on one side of the second driving gear 191, and is meshed with the second driving gear 191.

[0092] It should be noted that the first gear rod 233, the second gear rod 236 and the driving rod 225 described in this embodiment are located on the same axis.

[0093] Specifically, the structure and connection relationship of the liquid injection and sewage discharge joint drive mechanism 23 are further explained. The core driving force of the liquid injection and sewage discharge joint drive mechanism 23 comes from the driving rod 225. Once started, it can accurately control the opening and closing of the valves in the liquid injection pipe seat 17 and the sewage discharge pipe seat 19 according to the preset operating procedures. This mechanism ensures the smooth realization of automatic liquid injection and automatic sewage discharge functions. It is not only simple to operate and easy to control, but also significantly improves work efficiency and greatly reduces the labor intensity of operators.

[0094] Specifically, the driving rod 225 descends and first contacts with the first gear rod 233, and squeezes the first gear rod 233 to move downward. The downward movement of the first gear rod 233 synchronously drives the first vertical rod body 231 to move downward and stretches the second spring 232. During the downward movement of the first gear rod 233, the first driving gear 171 is also driven to rotate a set angle, so that the valve on the injection tube seat 17 is opened, so that the liquid can be injected into the cylindrical barrel 221 through the injection tube seat 17. When the set time is reached and the liquid inside the cylindrical barrel 221 is at the set liquid level, the driving rod 225 continues to descend and squeezes the first gear rod 233 to continue to move downward. During the downward movement of the first gear rod 233, the first driving gear 171 is again driven to rotate a set angle, so that the valve on the injection tube seat 17 is closed. The above is to realize the automatic injection operation. When the machine is shut down for maintenance, the driving rod 225 continues to descend and squeezes the first gear rod 233 to continue to move downward. The first gear rod 233 is moved downward, and is separated from the first driving gear 171. When the first vertical rod body 231 contacts the second vertical rod body 234, the second vertical rod body 234 is synchronously squeezed to move downward, and the third spring 235 is compressed. The second vertical rod body 234 moves downward and synchronously drives the second gear rod 236 to move downward, and contacts and meshes with the second driving gear 191 during the downward movement, and synchronously drives the valve in the sewage pipe seat 19 to open, so that the liquid inside the cylindrical cylinder 221 is discharged. After the set drainage time is reached, the driving rod 225 rises and synchronously drives the second driving gear 191 to reverse, thereby closing the valve. Since the first one-way transmission is set between the first driving gear 171 and the valve on the injection pipe seat 17, although the first gear rod 233 drives the first driving gear 171 to rotate during the rising process, it will not link the valve to open and close, thereby ensuring that the injection operation is stable and the use effect is good.

[0095] In summary, the electric heating throttling skid of the embodiment of the present invention is well-designed, accurately follows the standard process, realizes automatic liquid injection and desiccant removal, is easy to control, ensures stable operation of the equipment, extends its life, and the integrated automatic function greatly reduces manual operation, reduces costs, improves efficiency, and reduces labor intensity, with significant effects.
