Description

Technical Field

[0001] The utility model relates to a hydrogen generator, in particular to a hydrogen generator for portable comprehensive mud logging, belonging to the technical field of hydrogen generating equipment. Background Art

[0002] Mud logging is a key technology in geological exploration, which is used to collect and analyze gas and liquid samples of underground rock formations during the drilling process to help evaluate the properties and reserves of oil and gas reservoirs. The role of the hydrogen generator in mud logging is to provide hydrogen as the carrier gas for gas logging equipment. Due to its high purity and low molecular weight, hydrogen helps to improve the accuracy and sensitivity of gas analysis.

[0003] The hydrogen generator mainly consists of an electrolytic cell, a water tank, a power module, a gas separator and a control system. The working principle is to decompose water into hydrogen and oxygen through electrolysis. The hydrogen is collected for use, while the oxygen is discharged or treated. The control system monitors the whole process to ensure the normal operation of the equipment and the purity of hydrogen.

[0004] For an electrolytic water type hydrogen generator, an electrolyte solution, such as potassium hydroxide, usually needs to be added during use to enhance the conductivity of water. After adding potassium hydroxide to water, it needs to be stirred to ensure the uniform distribution of the electrolyte, and then the mixed solution is injected into the hydrogen generator from the water inlet through a beaker. The steps are relatively cumbersome and not convenient enough. In addition, when injecting the mixed solution from the water inlet of the hydrogen generator, it is easy to spill, resulting in waste of the solution and increasing the cleaning difficulty of the operation site. Therefore, we provide a hydrogen generator for portable comprehensive mud logging. Content of the Utility Model

[0005] The utility model provides a hydrogen generator for portable comprehensive mud logging, which can effectively avoid the spilling of the solution during the injection process. At the same time, potassium hydroxide can be stirred during the injection process of the solution, simplifying the operation steps and being relatively convenient.

[0006] The utility model is realized by the following technical solutions: it includes a hydrogen generator body, and the hydrogen generator body includes a water inlet arranged at the top of the hydrogen generator body, and a water injection and stirring mechanism is arranged on the side surface of the hydrogen generator body.

[0007] The water injection and stirring mechanism includes a mounting frame, on which a circular gear is rotatably connected. A driving bevel gear is fixed on one side of the circular gear. The top of the mounting frame is fixed with a water storage bucket with an open top. The bottom surface of the water storage bucket is rotatably connected through a rotary joint with a stirring shaft extending into the water storage bucket. Uniformly distributed stirring plates are fixed on the side surface of the stirring shaft. A driven bevel gear meshing with the driving bevel gear is fixed at the lower end of the stirring shaft. A toothed plate meshing with the circular gear is fixed on the side surface of the hydrogen generator body. The bottom of the water storage bucket is communicated with a hose connected to the water inlet. A guide rod is fixed on the side surface of the mounting frame. A slider slidably connected with the guide rod is fixed on the side surface of the hydrogen generator body.

[0008] Specifically, the top surface of the water storage bucket is threadedly connected with a sealing cover, and the outer contour of the sealing cover is cylindrical.

[0009] Specifically, the input end of the hose is connected to the bottom of the water storage bucket through bolts, and the output end of the hose is connected to the water inlet through bolts.

[0010] Furthermore, a coarse filter plate is placed at the top of the inner wall of the water storage bucket, and the outer contour of the coarse filter plate is circular.

[0011] Specifically, a support plate is fixed on the side surface of the hydrogen generator body, and a buffer pad in contact with the bottom surface of the mounting frame is fixed on the top surface of the support plate.

[0012] Furthermore, the hydrogen generator body includes handle grooves opened on the side surface of the hydrogen generator body, and the number of the handle grooves is two.

[0013] Specifically, uniformly distributed heat dissipation grooves are opened on the side surface of the hydrogen generator body, and a plurality of universal wheels are fixed on the bottom surface of the hydrogen generator body.

[0014] The present utility model provides a hydrogen generator for portable comprehensive mud logging, and the beneficial effects thereof are as follows:

[0015] 1. The hydrogen generator for portable comprehensive mud logging can pour water and potassium hydroxide into the water storage bucket with a larger opening, and it is not easy to spill. Then, the mounting frame drives the water storage bucket to rise. During the rising process, the circular gear meshing with the toothed plate will rotate. The circular gear will drive the driving bevel gear, the driven bevel gear, the stirring shaft, and the stirring plates to rotate in sequence. Thus, the water and potassium hydroxide inside the water storage bucket are fully stirred by the rotating stirring plates until the height of the connection between the hose and the water storage bucket is higher than the height of the connection between the hose and the water inlet. At this time, the solution inside the water storage bucket will be conveyed into the hydrogen generator body through the hose, which simplifies the operation steps and is relatively convenient.

[0024] Please refer to Figures 1 to 4 , the embodiment of the present utility model provides a hydrogen generator for portable comprehensive mud logging, including a hydrogen generator body 1. The hydrogen generator body 1 includes a water inlet 104 provided at the top of the hydrogen generator body 1. The hydrogen generator body 1 includes a handle groove 101 opened on the side surface of the hydrogen generator body 1. The number of the handle grooves 101 is two. Through the handle grooves 101, it is convenient to finely adjust the position of the device. The side surface of the hydrogen generator body 1 is provided with uniformly distributed heat dissipation grooves 103, which play a role in heat dissipation. The bottom surface of the hydrogen generator body 1 is fixed with a plurality of universal wheels 102. Through the universal wheels 102, it is convenient to move the device, improving the convenience.

[0025] Please pay special attention to referring to Figure 2 , Figure 3 and Figure 4, a water injection and stirring mechanism 2 is provided on the side of the hydrogen generator body 1. The water injection and stirring mechanism 2 includes a mounting frame 201. A support plate 3 is fixed to the side of the hydrogen generator body 1. A buffer pad 4 in contact with the bottom surface of the mounting frame 201 is fixed to the top surface of the support plate 3. The support plate 3 can buffer the mounting frame 201 to avoid severe vibration when the mounting frame 201 falls back. A circular gear 202 is rotatably connected to the mounting frame 201. A driving bevel gear 203 is fixed to one side of the circular gear 202. A water storage bucket 204 with an open top is fixed to the top of the mounting frame 201. A sealing cover 211 is threadedly connected to the top surface of the water storage bucket 204. The outer contour of the sealing cover 211 is cylindrical, and the sealing cover 211 plays a sealing role. A coarse filter plate 212 is placed on the top of the inner wall of the water storage bucket 204. The outer contour of the coarse filter plate 212 is circular. The bottom surface of the water storage bucket 204 is rotatably connected through a rotary joint with a stirring shaft 205 extending into the water storage bucket 204. Stirring plates 2051 are uniformly fixed to the side of the stirring shaft 205. The stirring plates 2051 can rotate driven by the stirring shaft 205. The water and potassium hydroxide can be stirred evenly by the rotating stirring plates 2051.

[0026] Please refer specifically to Figure 2 , Figure 3 and Figure 4, a driven bevel gear 206 meshing with the driving bevel gear 203 is fixed to the lower end of the stirring shaft 205, and a toothed plate 207 meshing with the circular gear 202 is fixed to the side of the hydrogen generator body 1. The circular gear 202 will rotate on the toothed plate 207 driven by the mounting frame 201. The rotating circular gear 202 will drive the driving bevel gear 203 to rotate, the rotating driving bevel gear 203 will drive the driven bevel gear 206 to rotate, and the rotating driven bevel gear 206 will drive the stirring shaft 205 and the stirring plate 2051 to rotate. Thus, the water and potassium hydroxide inside the water storage bucket 204 are stirred by the rotating stirring plate 2051. A hose 208 connected to the water inlet 104 is communicated with the bottom of the water storage bucket 204. The input end of the hose 208 is connected to the bottom of the water storage bucket 204 by bolts, and the output end of the hose 208 is connected to the water inlet 104 by bolts, which facilitates the disassembly of the hose 208 for regular cleaning. When the connection between the water storage bucket 204 and the hose 208 is higher than the connection between the hose 208 and the water inlet 104, the stirred solution inside the water storage bucket 204 will flow into the hydrogen generator body 1. A guide rod 209 is fixed to the side of the mounting frame 201, and a slider 210 slidably connected to the guide rod 209 is fixed to the side of the hydrogen generator body 1. When the mounting frame 201 drives the guide rod 209 to rise, the guide rod 209 will slide on the slider 210. The cooperation of the guide rod 209 and the slider 210 can make the mounting frame 201 move more stably. Preferably, an electric push rod can be installed on the side of the hydrogen generator body 1 to drive the mounting frame 201 to rise by the electric push rod, which is more labor-saving.

[0027] Working principle: When in use, first remove the sealing cover 211 on the water storage bucket 204, then pour water and potassium hydroxide into the water storage bucket 204 with a larger opening, and it is not easy to spill. Then drive the water storage bucket 204 to rise by the mounting frame 201. During the rising process, the circular gear 202 meshing with the toothed plate 207 will rotate. The circular gear 202 will drive the driving bevel gear 203, the driven bevel gear 206, the stirring shaft 205, and the stirring plate 2051 to rotate in sequence. The water and potassium hydroxide inside the water storage bucket 204 are fully stirred by the rotating stirring plate 2051 until the height of the connection between the hose 208 and the water storage bucket 204 is higher than the height of the connection between the hose 208 and the water inlet 104. At this time, the solution inside the water storage bucket 204 will be transported from the hose 208 to the hydrogen generator body 1, which simplifies the operation steps and is more convenient.
