Description
Technical Field
[0001] This utility model relates to the field of rock screening technology, specifically to a reservoir rock particle size classification and screening device. Background Technology
[0002] In the fields of petroleum geology and mining, grain size analysis of reservoir rocks is a crucial step in assessing reservoir properties. Traditional grain size screening typically employs manual or simple mechanical vibrating screens, which suffer from low screening efficiency, easy particle clogging of the screen, and poor adaptability to multi-stage continuous screening. This affects the accuracy of analytical data and work efficiency, making it difficult to meet the needs of large-volume, refined sample processing. Utility Model Content
[0003] The purpose of this invention is to provide a reservoir rock particle size classification and screening device that is reasonably designed and easy to use, which can effectively solve the defects and shortcomings of the existing technology.
[0004] To achieve the above objectives, this utility model adopts the following technical solution: it includes a storage bin, an elevator, a mounting frame, and a screening tank. The storage bin contains an elevator, and a mounting frame is located on one side of the elevator. The mounting frame contains screening tanks arranged symmetrically both vertically. It also includes: The sliding blocks are of several kinds and are fixed on the front and rear side walls of the screening tank in equal quantities and at equal intervals. The sliding blocks are slidably set in the sliding grooves on the front and rear inner walls of the mounting frame. Vibration springs are fixed on the upper and lower side walls of the sliding blocks, and the other end of the vibration springs is fixedly connected to the inner wall of the sliding groove. A toggle mechanism is provided inside one side wall of the mounting frame and is connected to the screening tank. The collecting hopper is located on the lower side of the screening tank. The outer peripheral wall of the collecting hopper is fixedly connected to the inner wall of the mounting frame. A discharge pipe is inserted and fixed at the front end of the collecting hopper. The front end of the discharge pipe passes through the front side wall of the mounting frame and is exposed on the front side of the mounting frame. The guide plate consists of two plates, which are respectively fixed on the inner bottom wall of the screening tank on the side away from the elevator. One side of the guide plate is located in the middle of the outlet of the screening tank, and the other side of the guide plate is tilted and fixedly connected to one side of the inner wall of the screening tank. The tilting directions of the upper and lower guide plates are opposite. Through the above technical solution, the material in the storage box is fed upward into the upper screening pool by the elevator. The screening pool is driven to shake by the spring force of the vibrating spring through the actuating mechanism, thereby improving the screening effect. The material is classified and screened by the upper and lower screening pools. The material screened by the lower screening pool falls into the collection hopper and is finally discharged through the No. 1 discharge pipe. The material on the two screening pools moves to one side of the guide plate, which facilitates the classification and discharge of the material.
[0005] As a further improvement of this utility model, a second discharge pipe is fixed on one side wall of the screening tank, and the opening of the second discharge pipe abuts against the outer side of the guide plate. The above technical solution allows the material in the screening tank to be discharged through the No. 2 discharge pipe, thus avoiding the re-mixing of materials after screening by the two screening tanks.
[0006] As a further improvement of this utility model, the lower end of the second discharge pipe is fixed with a discharge hopper, and the two discharge hoppers are arranged symmetrically front and back. The above technical solution facilitates the discharge of materials from the No. 2 discharge pipe.
[0007] As a further improvement of this utility model, several guide rods are equidistantly arranged inside the front and rear side walls of the mounting frame, and the guide rods are respectively inserted into several corresponding upper and lower vibration springs and sliding blocks; The above technical solution can provide some support for the vibration spring and prevent it from deforming.
[0008] As a further improvement of this utility model, the actuating mechanism includes: Two actuating blocks are fixed on the outer wall of one side of the screening tank, and the actuating blocks are movably arranged in a rectangular groove on the inner wall of one side of the mounting frame. The rotating rod consists of two rods, which are screwed one-to-one onto the inner wall of one side of the rectangular groove via bearings. The two rotating rods are connected by a synchronous wheel transmission assembly. Two actuating rods are fixed on the outer ring wall of one end of the rotating rod inside the rectangular groove. The actuating rods are set to engage with the actuating block. A toggle motor is embedded and fixed in one side wall of the mounting bracket, and the output shaft of the toggle motor is connected to one of the rotating rods through a synchronous pulley transmission assembly. With the above technical solution, the actuating motor is started, and the actuating motor drives the rotating rod connected to it to rotate through the synchronous wheel transmission assembly. The rotating rod drives another rotating rod to rotate through the synchronous wheel transmission assembly. The rotating rod drives the actuating rod to rotate. When the actuating rod comes into contact with and pushes the actuating block, it drives the actuating block to move downward. The actuating block drives the screening tank to move downward. When the actuating rod separates from the actuating block, it drives the sliding block to move upward under the push of the vibration spring, thereby generating vibration.
[0009] As a further improvement of this utility model, a guide frame is movably inserted into the periphery of the collection hopper, and the upper side of the guide frame is fixed to the outer bottom wall of the screening tank below. The above technical solution can prevent materials falling from the screening tank at the bottom from falling to the outside of the collection hopper.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: The reservoir rock particle size classification and screening device of this utility model combines a toggle mechanism and a vibration spring to achieve efficient screening, and utilizes a double-layer screening pool and guide plate design to significantly improve screening efficiency and the convenience of automatic material classification and collection. This utility model has the advantages of reasonable setting and low manufacturing cost. Attached Figure Description

[0016] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0017] Example 1: like Figures 1-4 As shown, this embodiment includes a storage bin 1, an elevator 2, a mounting frame 3, and a screening tank 4. The elevator 2 is installed inside the storage bin 1, and the mounting frame 3 is installed on the right side of the elevator 2. The screening tank 4 is symmetrically arranged inside the mounting frame 3. It also includes: Sliding blocks 4-1, of which there are several, are welded and fixed to the front and rear side walls of the screening tank 4 in equal quantities and at equal intervals. The sliding blocks 4-1 are slidably disposed in the sliding grooves on the front and rear inner walls of the mounting frame 3. Vibration springs 5 are welded and fixed to the upper and lower side walls of the sliding blocks 4-1, and the other end of the vibration springs 5 is welded and fixed to the inner wall of the sliding groove. Several guide support rods 12 are equally spaced in the front and rear side walls of the mounting frame 3. The guide support rods 12 are respectively inserted into the upper and lower corresponding vibration springs 5 and sliding blocks 4-1, which can provide a certain support for the vibration springs 5 and prevent the vibration springs 5 from deforming. A toggle mechanism 6 is disposed inside one side wall of the mounting frame 3 and is connected to the screening tank 4. The collecting hopper 7 is located below the screening pool 4. The outer peripheral wall of the collecting hopper 7 is welded and fixed to the inner wall of the mounting frame 3. A discharge pipe 8 is inserted into and welded to the front end of the collecting hopper 7. The front end of the discharge pipe 8 passes through the front side wall of the mounting frame 3 and is exposed on the front side of the mounting frame 3. A guide frame 13 is movably inserted into the peripheral wall of the collecting hopper 7. The upper side of the guide frame 13 is welded and fixed to the outer bottom wall of the screening pool 4 below, which can prevent the material screened and dropped from the screening pool 4 below from falling to the outside of the collecting hopper 7. Two guide plates 9 are welded and fixed to the inner bottom wall of the screening tank 4 on the side away from the elevator 2. The right side of the guide plate 9 is located in the middle of the outlet of the screening tank 4, and the left side of the guide plate 9 is tilted and fixedly connected to the inner wall of one side of the screening tank 4. The tilting directions of the upper and lower guide plates 9 are opposite. A second discharge pipe 10 is welded and fixed to one side wall of the screening tank 4. The opening of the second discharge pipe 10 abuts against the outer side of the guide plate 9, and the material on the screening tank 4 can be discharged through the second discharge pipe 10 to avoid the material after screening by the two screening tanks 4 being mixed again. A discharge hopper 11 is welded and fixed to the lower end of the second discharge pipe 10. The two discharge hoppers 11 are symmetrically arranged front and back to facilitate the discharge of the material in the second discharge pipe 10.
[0018] Example 2: See Figure 2 , Figure 3 As shown, based on Embodiment 1, the actuating mechanism 6 includes: Two actuating blocks 6-1 are respectively welded and fixed on the outer wall of the left side of the screening tank 4. The actuating blocks 6-1 are movably arranged in the rectangular groove on the inner wall of the left side of the mounting frame 3. Rotating rod 6-2, there are two rotating rods 6-2, and they are screwed onto the inner wall of the left side of the rectangular groove one to one via bearings. The two rotating rods 6-2 are connected by a synchronous wheel transmission assembly. Two actuating rods 6-3 are welded and fixed on the outer ring wall of one end of the rotating rod 6-2 inside the rectangular groove. The actuating rods 6-3 are set to abut against the actuating block 6-1. The actuating motor 6-4 is embedded in and fixed to the left side wall of the mounting bracket 3 by bolts. The output shaft of the actuating motor 6-4 is connected to the upper rotating rod 6-2 through a synchronous pulley transmission assembly.
[0019] When using this invention, the material in the storage bin 1 is fed upwards into the screening tank 4 via the elevator 2. The actuating motor 6-4 is started, and the actuating motor 6-4 drives the connected rotating rod 6-2 to rotate via the synchronous pulley transmission assembly. This rotating rod 6-2 drives another rotating rod 6-2 to rotate via the synchronous pulley transmission assembly. The rotating rod 6-2 drives the actuating rod 6-3 to rotate. When the actuating rod 6-3 contacts and pushes against the actuating block 6-1, it drives the actuating block 6-1 to move downwards. The actuating block 6-1 then drives... When the screening tank 4 moves downward and the actuating rod 6-3 separates from the actuating block 6-1, the sliding block 4-1 moves upward under the push of the vibration spring 5. The sliding block 4-1 causes the screening tank 4 to shake, thereby creating vibration to improve the screening effect. The material is graded and screened through the upper and lower screening tanks 4. The material screened by the lower screening tank 4 falls into the collection hopper 7 and is finally discharged through the first discharge pipe 8. The material on the two screening tanks 4 moves to one side of the guide plate 9, which facilitates the classification and discharge of the material.
[0020] Compared with the prior art, the beneficial effects of this specific embodiment are as follows: 1. By driving the toggle lever 6-3 to periodically push the toggle block 6-1 through the toggle motor 6-4, and combined with the reset action of the vibration spring 5, the screening tank 4 generates efficient and continuous micro-vibration, which effectively prevents screen blockage and significantly improves screening efficiency and effect. 2. The double-layer screening tank 4 with symmetrical upper and lower arrangement can complete multi-stage fine screening of materials in one go. Through the cooperation of guide plate 9 and independent discharge port, the automatic classification and collection of materials of different particle sizes can be realized, avoiding material mixing. 3. The guide plate 9, combined with the discharge hopper 11 which is symmetrically arranged front and back, can guide the material on the screen to be discharged in an orderly manner. Moreover, the discharge directions of the upper and lower layers are opposite, and the structure is reasonable, which greatly facilitates the classification, discharge and subsequent collection and processing of materials. 4. By setting guide support rods 12 inside the vibration spring 5 and sliding block 4-1, stable support is provided for the vibration components, which can effectively prevent the vibration spring 5 from twisting or plastic deformation during long-term operation, and ensure the long-term reliable operation of the vibration system.
[0021] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
