[0002] Rock sample pretreatment equipment is a key piece of equipment in geological and petroleum exploration and laboratory analysis. It is used to crush, clean, dry and screen rock samples to meet the accuracy requirements of subsequent experiments.

[0003] In the existing process, for source rock samples, the core is first cleaned with a toluene-methanol mixture to remove residual hydrocarbons and salts, and then pore water is removed using a direct drying device. However, during the drying process, considering that the rock blocks have protruding corners and small depressions, this large-area drying method will cause the drying heat at the protruding corners and small depressions to be inconsistent with the drying heat at the flat surface. Over time, this will lead to problems such as over-drying and fragmentation of the protruding corners and under-drying of the depressions. Therefore, it is necessary to improve the range of the drying steam jet. Utility Model Content

[0004] To address the aforementioned shortcomings of existing technologies, this invention provides a rock sample pretreatment device for shale oil source rock analysis. This device effectively solves the problem of uneven drying heat caused by large-area drying methods in existing technologies, where rock blocks have protruding angles and small depressions.

[0005] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a rock sample pretreatment device for shale oil source rock analysis, including a support mechanism. The support mechanism includes a stabilizing box, the inner cavity of which is fitted with a drying mechanism and a receiving mechanism. A cover plate is snapped onto the top of the stabilizing box. A base is fixedly connected to the inner surface of the stabilizing box, and a triangular block is fixedly connected to the top of the base. The drying mechanism also includes a servo motor fixedly sleeved with the side of the triangular block. A worm gear is inserted into the output end of the servo motor. The teeth of the worm gear mesh with a worm wheel. A steam cylinder is fixedly sleeved at the center of the worm wheel. A straight air outlet is connected to the side of the steam cylinder. A hinge seat and a flap plate are fitted into the inner cavity of the end face of the straight air outlet.

[0006] Furthermore, a hinge seat is fixedly connected to the inner side of the air outlet cylinder. Multiple hinge seats are provided and arranged in a ring array in the inner cavity of the air outlet cylinder. The surface of the hinge seat is rotatably connected to the flap plate.

[0007] Furthermore, the number of the air outlet cylinders is three, and the three air outlet cylinders are arranged in a ring on the outer surface of the steam cylinder, and an aluminum foil layer is attached to the inner cavity of the steam cylinder.

[0008] Furthermore, a gas delivery pipe is fixedly fitted on the top of the steam cylinder, and a pump is connected to the end face of the gas delivery pipe. A flange is fixedly connected to the bottom of the pump, and the flange is embedded in the upper surface of the base.

[0009] Furthermore, a triangular block is fixedly connected to the outer surface of the servo motor, the lower surface of the triangular block is inserted into the base, and a support base is adapted to be installed on the end face of the worm gear, the bottom of the support base is fixedly connected to the base.

[0010] Furthermore, a right-angle rod is fixedly connected to the outer surface of the steam outlet cylinder, the end face of the right-angle rod is inserted into the side of the steam cylinder, and a bearing seat is fixedly sleeved at the bottom of the steam cylinder, the bearing seat being engaged in the fitting groove opened in the base.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] See attached document Figure 1-5A rock sample pretreatment device for shale oil source rock analysis includes a support mechanism 100. The support mechanism 100 includes a stabilizing box 101. The inner cavity of the stabilizing box 101 is fitted with a drying mechanism 200 and a receiving mechanism 300. A cover plate 102 is snapped onto the top of the stabilizing box 101. A base 103 is fixedly connected to the inner surface of the stabilizing box 101. A triangular block 202 is fixedly connected to the top of the base 103. The drying mechanism 200 also includes a servo motor 201 fixedly sleeved with the side of the triangular block 202. A worm gear 203 is inserted into the output end of the servo motor 201. The teeth of the worm gear 203 mesh with a worm wheel 205. A steam cylinder 207 is fixedly sleeved at the center of the worm wheel 205. An exhaust cylinder 211 is connected to the side of the steam cylinder 207. A hinge seat 213 and a flap plate 214 are fitted into the inner cavity of the end face of the exhaust cylinder 211.

[0024] The coordinated arrangement of the stabilizing box 101 with the drying mechanism 200 and the receiving mechanism 300 enables the drying mechanism 200 to stably dry the rock blocks, meeting the drying process requirements of different locations on the rock block surface. The receiving mechanism 300 also provides a place for the rock blocks. The fixed sleeve of the triangular block 202 and the servo motor 201 helps reduce the shaking of the servo motor 201 during operation. The meshing of the worm gear 203 and the worm wheel 205 helps the steam cylinder 207 rotate, further pushing the steam to the inside of the steam cylinder 207 under the action of centrifugal force, helping to concentrate the steam output. The steam outlet straight cylinder 2... The cooperation between 11 and the hinge seat 213 and the flap plate 214 allows a large amount of steam to drive the flap plate 214 to rotate when the steam flows, thereby expanding the port surface of the outlet cylinder 211. At the same time, more steam can be transmitted for drying the protruding corners and concave blocks on the rock surface. When the amount of steam is insufficient, the steam is not enough to drive the flap plate 214 or flows out from the gaps of several flap plates 214. It can also be used for the continuous drying requirements of flat areas on the rock surface. This adaptive control of steam delivery is applicable to different drying occasions, making the drying targeted and improving the drying quality.

[0025] A hinge seat 213 is fixedly connected to the inner side of the air outlet cylinder 211. Multiple hinge seats 213 are provided and arranged in a ring array in the inner cavity of the air outlet cylinder 211. The surface of the hinge seat 213 is rotatably connected to the flap plate 214.

[0026] The rotation of multiple hinge seats 213 and flap plates 214 creates gaps between the flap plates 214, which facilitates the uniform flow of steam and demonstrates the drying function of the device.

[0027] There are three straight air outlet cylinders 211, which are arranged in a ring on the outer surface of the steam cylinder 207. An aluminum foil layer is fitted inside the steam cylinder 207. A gas delivery pipe 208 is fixedly sleeved on the top of the steam cylinder 207. The end face of the gas delivery pipe 208 is connected to a pump 209. A flange 210 is fixedly connected to the bottom of the pump 209. The flange 210 is embedded in the upper surface of the base 103.

[0028] The annular array of the exhaust cylinder 211 significantly increases the effective area of ​​the drying steam, further improving drying efficiency. The aluminum foil layer attached to the steam cylinder 207 helps reduce the heat conduction speed of the steam, allowing more high-temperature steam to be directly transmitted, indirectly ensuring drying quality. The connection and cooperation between the gas pipe 208, the pump 209, and the steam cylinder 207 ensures that steam can be continuously generated and transmitted, meeting the continuous drying needs of the rock. The flange 210 is fitted and connected to the upper surface of the base 103, which helps ensure the stable operation of the pump 209 and makes the steam output more uniform, indirectly helping the drying process of the rock to proceed continuously.

[0029] A triangular block 202 is fixedly connected to the outer surface of the servo motor 201. The lower surface of the triangular block 202 is inserted into the base 103. A support base 204 is fitted to the end face of the worm gear 203. The bottom of the support base 204 is fixedly connected to the base 103.

[0030] Afterwards, the insertion of the triangular block 202 into the base 103 enables the servo motor 201 to output power stably, which helps the steam cylinder 207 to rotate stably. The steam is continuously pushed under the action of centrifugal force, which at the same time accelerates the escape of the steam remaining in the steam cylinder 207, preventing the steam cylinder 207 from being compressed and expanded, thus avoiding damage.

[0031] A right-angle rod 212 is fixedly connected to the outer surface of the steam outlet cylinder 211. The end face of the right-angle rod 212 is inserted into the side of the steam cylinder 207. A bearing seat 206 is fixedly sleeved at the bottom of the steam cylinder 207. The bearing seat 206 is snapped into the adapter groove opened in the base 103.

[0032] Next, the fixed connection between the right-angle rod 212 and the outlet cylinder 211 allows the outlet cylinder 211 to stably spray air in a fixed position, preventing steam from escaping due to vibration and ensuring a relatively stable steam ejection trajectory. The fixed sleeve between the bearing seat 206 and the steam cylinder 207 can further ensure the relative stability of the steam cylinder 207 during rotation, which is conducive to the stable containment of steam.

[0033] The receiving mechanism 300 includes a drive motor 301, which is fixedly connected to the outer side of the stabilizing box 101 via a disc frame. The output end of the drive motor 301 is inserted into a receiving roller 302, and the end face of the receiving roller 302 is snapped with a side block 303. There are several flip plates 214, and the several flip plates 214 are aligned at the center.

[0034] The insertion of the drive motor 301 into the receiving roller 302 allows some rock chips on the surface of the rock block to be stirred and mixed. At the same time, the engagement of the side block 303 into the receiving roller 302 facilitates the rapid addition of rock chips, preparing for the cleaning and drying of the rock chips.

[0035] Working principle: First, the rock block is added into the inner cavity of the receiving roller 302 via the side block 303. Then, the drive motor 301 is started, allowing the rock block to be thrown off the inner cavity surface of the receiving roller 302 by centrifugal force. Next, the servo motor 201 is turned on. After receiving the power from the output end of the servo motor 201, the worm gear 203 meshes with the worm wheel 205 for transmission. Then, the steam cylinder 207 rotates synchronously. The air outlet cylinder 211 is connected and installed with the steam cylinder 207. At the same time, the pump 209 is started. Under the stabilizing effect of the flange 210, the steam is delivered to the steam cylinder 207 through the air supply pipe 208. Further, through the rotational cooperation of the hinge seat 213 and the flap plate 214, the steam transmission volume is adaptively adjusted, so that the steam directly contacts the outer wall of the receiving roller 302, completing the drying process of the rock block. This device is highly practical and suitable for application.

[0036] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
