[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0041] After the experiment studying the "influence of abrasive particles on wet abrasive wear of hydraulic machinery, etc." is completed, the size and shape of the abrasive particles need to be analyzed to reveal the wear mechanism of the research object under different sizes and shapes of abrasive particles. Therefore, the material after the experiment needs to be processed to separate and dry the abrasive particles of different sizes for subsequent analysis. In order to select suitable abrasives, actual working conditions can be investigated, the physical properties of the abrasives can be analyzed, and abrasives that meet the actual conditions can be selected for the experiment. To achieve the above requirements, this laboratory cross-vibration separation and drying device was designed.

[0042] like Figure 1As shown, this embodiment of the invention provides a laboratory cross-type vibration separation and drying device, including a base 6, a housing 7, a drying chamber 4, a vibration system, and a display screen 3. The housing 7 is mounted on top of the base 6, the vibration system is mounted on the top of the inner cavity of the housing 7, and the drying chamber 4 is mounted on the bottom of the vibration system; wherein,

[0043] The drying chamber 4 has multiple layers of screens with different apertures arranged along the height direction. Heating tubes 405 are arranged along the material descent path of each layer of screens and are configured to dry the material.

[0044] The vibration system is set along the height direction of the drying box 4. The vibration system drives the drying box 4 to perform multi-directional degree of freedom movement in a cross vibration mode. The vibration system includes a Y-axis vibration system 1 and an X-axis vibration system 2. The Y-axis vibration system 1 and the X-axis vibration system 2 are set up and down along the height direction, and the Y-axis vibration system 1 and the X-axis vibration system 2 are movably connected.

[0045] The Y-axis vibration system 1 includes a set of crank-slider mechanisms, the crank-slider mechanism including a Y-axis slider 105 that reciprocates along the Y-axis direction, the Y-axis slider 105 driving the X-axis vibration system 2 to reciprocate along the Y-axis direction;

[0046] The X-axis vibration system 2 includes a set of cam mechanisms, which drive the drying chamber 4 to reciprocate along the X-axis direction via baffle 204.

[0047] In this embodiment of the invention, the Y-axis vibration system 1 is driven by a motor and transmitted by a crank-slider mechanism, which drives the drying box 4 to reciprocate in the Y-axis direction and rotate around the X-axis. The X-axis vibration system 2 is driven by a motor and transmitted by a cam mechanism, which realizes the reciprocating motion of the drying box 4 in the X-axis direction. The superposition of the X-axis and Y-axis motions gives the drying box 4 three degrees of freedom, which can make the screening efficiency higher and the screening effect better.

[0048] The following example further illustrates the movable connection between the Y-axis vibration system 1 and the X-axis vibration system 2 mentioned above. For instance, in some embodiments of this application, in order to give the drying chamber 4 three degrees of freedom, the Y-axis vibration system 1 and the X-axis vibration system 2 are connected by a pin. The Y-axis slider 105 drives the X-axis vibration system 2 to reciprocate along the Y-axis direction while rotating around the X-axis direction with the pin as the center. The drying chamber 4 has at least three degrees of freedom, which improves the screening effect.

[0049] like Figure 2As shown below, the crank-slider mechanism mentioned above will be illustrated by example. For instance, in some embodiments of this application, the crank-slider mechanism includes a Y-axis slide rail 104 arranged along the Y-axis direction and a reduction motor. It should be noted that the reduction motor referred to here is a first reduction motor 101. The output end of the first reduction motor 101 is connected to a crankshaft 102. The crankshaft 102 is connected to the Y-axis slider 105 by a connecting rod 103. The Y-axis slider 105 reciprocates along the length direction of the Y-axis slide rail 104. The bottom pin of the Y-axis slider 105 is connected to a connecting rod 106.

[0050] Understandably, the Y-axis vibration system 1 is driven by the first reduction motor 101 and transmitted by the crank-slider mechanism, which drives the drying box 4 to reciprocate in the Y-axis direction and rotate around the X-axis.

[0051] like Figure 3 As shown, the cam mechanism mentioned above is illustrated below. For example, in some embodiments of this application, the cam mechanism includes a geared motor, the output end of which is connected to a cam 202, and a roller 201 is installed at the contact position between the baffle 204 and the cam 202. It should be noted that the geared motor referred to here is the second geared motor 207;

[0052] With this configuration, the X-axis vibration system 2 is driven by the second reduction motor 207, transmitted by the cam mechanism, and uses the spring 203 to realize the reciprocating motion of the drying box 4 in the X-axis direction;

[0053] See also Figure 3 Furthermore, in order to connect the Y-axis vibration system 1 and the X-axis vibration system 2 into a whole and to ensure the stability of the X-axis vibration system 2 during operation, the X-axis vibration system 2 also includes a bracket and an X-axis slide rail 205 arranged along the X-axis direction on the inner side of the bracket. An X-axis slider 206 is slidably connected along the length direction of the X-axis slide rail 205. The side of the X-axis slider 206 away from the X-axis slide rail 205 is fixedly connected to the baffle 204. One end of the spring 203 is connected to the middle of the baffle 204, and the other end of the spring 203 is connected to the end of the X-axis slide rail 205.

[0054] The purpose of this arrangement is that, while the second reduction motor 207 drives the cam 202 to contact the roller 201 mounted on the baffle 204, the cam 202 drives the drying box 4 to move in the X-axis direction through the baffle 204. When the cam 202 rotates to the side away from the roller 201, the baffle 204 returns to the initial state under the elastic action of the spring 203. This process is repeated to achieve the reciprocating motion of the drying box 4 in the X-axis direction.

[0055] More specifically, the bracket mentioned above is illustrated below. The bracket includes a hollow steel plate 210, which is a hollow flat plate. The two ends of the flat plate are bent at 90 degrees. At both ends of the bent portion of each hollow steel plate 210, a second angle steel 209 is bolted to it. The other ends of the two second angle steels 209 are connected together by a first angle steel 208 to form a bracket with a trapezoidal side projection.

[0056] Furthermore, in order to prevent rigid collisions between the drying chamber 4 and the first angle steel 208, limit springs 211 are installed at the bottom of both ends of each of the first angle steel 208 to prevent rigid collisions between the drying chamber 4 and the first angle steel 208 during the swing process, and to buffer the drying chamber 4.

[0057] The following describes the specific connection method between the Y-axis vibration system 1 and the X-axis vibration system 2. The screw hole at the bottom of the connecting rod 106 of the Y-axis vibration system 1 corresponds to the screw hole on the upper surface of the hollow steel plate 210, and they are fixed together by bolts.

[0058] like Figure 8 As shown, the baffle 204 mentioned above will be illustrated below. For example, in some embodiments of this application, in order to better connect the X-axis vibration system 2 with the drying box 4, the baffle 204 includes a slider connecting plate 2042. The bottom left and right sides of the slider connecting plate 2042 are integrally formed with bearing seats 2043. A side baffle 2041 is installed on the rear side of the slider connecting plate 2042. A roller fixing plate 2046 is installed on the top front side of the side baffle 2041. A hook fixing plate 2045 is installed in the middle front side of the side baffle 2041. A hook 2044 is installed on the side of the hook fixing plate 2045.

[0059] like Figure 5 As shown, in order to realize the weighing function, this device also includes a weighing device, which adopts a cantilever beam type weighing sensor 401 and is set in the uppermost layer inside the drying oven 4.

[0060] It should be noted that the cantilever beam load cell 401 is model E10F-200g cantilever beam load cell; this sensor has high accuracy, small measuring range, and is easy to install, making it more suitable for weighing dry materials.

[0061] like Figure 4 As shown, for convenient weighing, a leveling device 5 is also included. The leveling device 5 is located below the drying oven 4 and has a liftable horizontal top plate 501.

[0062] Specifically, the leveling device 5 mentioned above is illustrated by an example. The leveling device 5 also includes a leveling device base 505. A first bevel gear 503 is rotatably mounted on the top of the leveling device base 505 via a first bearing 504. A screw 502 is threadedly connected to the inner wall of the first bevel gear 503. One end of the screw 502 extends out of the top of the first bevel gear 503 and is fixed at the bottom center of the top plate 501. The other end of the screw 502 extends out of the bottom of the leveling device base 505 and is meshed with a second bevel gear 508 in a direction perpendicular to the first bevel gear 503. A sleeve 507 is installed on the right side of the second bevel gear 508, and a hand crank 506 is installed on the right end of the sleeve 507.

[0063] With this setup, after the drying and screening processes are completed, manually turning the hand crank 506 will drive the second bevel gear 508 to rotate. The second bevel gear 508 will mesh with the first bevel gear 503. The first bearing 504 bushing connected to the first bevel gear 503 has internal threads, and the bushing meshes with the screw 502, causing the screw 502 and the top plate 501 to rise, thus leveling the drying chamber 4.

[0064] like Figure 6 and Figure 7 As shown, the drying box 4 has three layers of screens inside, arranged from top to bottom according to the size of the screen holes. The bottom of the drying box cavity is provided with a slag receiving tray, and the top side of the drying box 4 is connected to a feed pipe 411.

[0065] Specifically, the three layers of screens are arranged from top to bottom as a primary screen 404, a secondary screen 406, and a tertiary screen 407. The drying chamber 4 also includes an internal support 402. Each level of screen is separated by a screen support frame 408, and the screen support frame 408 is connected to the internal support 402. The top and front and rear ends of the internal support 402 are equipped with ear plates. The two ear plates are connected together by a connecting rod 409. The connecting rod 409 passes through two through holes of the bearing seat 2043 and is connected to the ear plates. A second bearing 410 is installed at the connection point.

[0066] The drying oven 4 is designed with a drying device and a weighing device. The drying device is placed below each screen. This invention uses infrared radiation drying and has three rows of heating tubes inside, with a single row power of 1.2KW.

[0067] The main design of this invention is divided into four parts. The top part is the Y-axis vibration system 1, mainly composed of a motor and a crank-slider mechanism. Below this is the X-axis vibration system 2, mainly composed of a motor and a cam-slider mechanism. Below that is the drying chamber 4, which contains a weighing device and three layers of screens, with a drying device located below the screens. A leveling device is located at the bottom for leveling the chamber after the drying process, facilitating weighing. The material is fed through the feed pipe 411. Upon entering the chamber, the vibration effectively separates the material. This design uses a three-layer screen, with the screen mesh size selectable according to specific experimental requirements. To prevent contamination of the chamber by small particles and to address issues with excessive moisture content in some sand materials, a slag receiving tray 403 is provided at the bottom. The required humidity value is observed on the humidity display, and the machine is stopped. After the infrared sensor indicator light goes out, the chamber is leveled, the door is opened, and the material is retrieved for experimental research.

[0068] In addition, the present invention also calculates the ratio of material weight and motor speed, and can select the corresponding motor power according to the weight of wet material to achieve better screening effect.

[0069] The slider velocity of the Y-axis vibration system changes with the crank angle, and the rate of change is... The displacement X changes with the rotation angle, and the rotation angle θ changes with time.

[0070] Therefore

[0071]

[0072]

[0073] Where R is the crank length and L is the connecting rod length.

[0074]

[0075] but

[0076]

[0077] The maximum speed of the slider can be obtained. In this invention, R=23mm.

[0078] According to the experiment, we can obtain

[0079] The experimental results show that the three speed settings correspond to dry material weights of 60g, 120g, and 200g, respectively.

[0080] Therefore, the first speed setting should be used when the weight of the dry material is not higher than 60g, the second speed setting should be used when the weight is not higher than 120g, and the third speed setting should be used when the weight is not lower than 120g.

[0081] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
