TECHNICAL FIELD

[0001] The present application relates to the technical field of screening and testing machinery, in particular to a modular reconfigurable flip-flow screening testing machine. BACKGROUND

[0002] The existing flip-flow screening experimental device is single in form. The existing flip-flow experimental device is either a single-sieve surface experimental machine, which cannot realize the experimental process of inclined sieve surface screening, or a pilot experimental machine containing several sieve surfaces, which cannot realize the observation of the screening process, has few operable parameters, and occupies a large space, and cannot flexibly respond to experiments of various flip-flow screening forms. With the development of existing screening technology, different specifications of experimental devices need to be designed for different working conditions, which has high investment cost, and the existing flip-flow screening experimental device cannot meet the experimental needs of research and design of multiple models or new flip-flow screens. SUMMARY

[0003] The present application aims to provide a modular reconfigurable flip-flow screening testing machine to solve the problems existing in the prior art. The modular reconfigurable flip-flow screen is flexible and convenient to assemble different structures, and is suitable for specific flip-flow screens. The single-layer transparent glass cover can directly observe the movement of the sieve surface and the material, and obtain experimental data during the experiment. The inclined frame under the multi-layer flip-flow screen can simulate the movement of the material in the field environment and observe the real working conditions. Moreover, since the basic component unit is a single sieve surface, the driving strength of each section of the flip-flow screen can be adjusted individually after the flip-flow screen is composed of multiple sieve surfaces, which provides convenience for experimental research.

[0004] The modular reconfigurable flip-flow screening experimental machine has the following advantages compared with the traditional flip-flow screen:

[0005] (1) The modular reconfigurable flip-flow screen can form a multi-flip-flow screen experimental device, a new flip-flow experimental device of impact type, and a horizontal vibration flip-flow experimental device through the assembly of multiple flip-flow modules, which can meet the experimental needs of research and development of different new flip-flow screening equipment;

[0006] (2) The modular reconfigurable flip-flow screening testing machine is flexible and convenient to assemble, and is suitable for different specifications of laboratory environment. It has small floor area and reduces the waste of valuable laboratory space;

[0007] (3) The single modular reconfigurable flip-flow screen testing machine can be arbitrarily assembled into a multi-sieve surface flip-flow screen;

[0008] (4) After the modular reconfigurable flip-flow screening testing machine is assembled into a multi-sieve surface flip-flow screen, the driving strength of each section of the flip-flow screen can be adjusted individually.

[0009] In summary, the modular reconfigurable relaxation screen test machine can meet the experimental needs of the research and development of different new relaxation screen equipment, and has obvious advantages in land occupation, adaptation to working conditions and parameter adjustment.

[0010] To achieve the above object, the application provides the following scheme.

[0011] The application provides a modular reconfigurable relaxation screen test machine, which comprises a relaxation body unit, a support, a feed inlet, a cover device, a blind plate, a support, a motor frame, a discharge outlet and a heightening frame.

The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0037] The purpose of this invention is to provide a modular and reconfigurable tension screening tester to solve the problems existing in the prior art.

[0038] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] like Figure 8As shown, the tension body unit 1 is the core component of the modular reconfigurable tension screening test machine. It consists of different numbers or positions of tension body units 1, along with components such as the combinable support 2, feed inlet 3, cover device 4, blind plate 5, support 6, motor frame 7, discharge port 8, and elevation frame 9. The drive end module is arranged diagonally with the other parts, allowing for flexible combination of multiple modules to form single-screen-surface tension-reaction, single-screen-surface tension-reaction, inclined four-screen-surface tension-reaction, inclined four-screen-surface tension-reaction, inclined eight-screen-surface tension-reaction, inclined eight-screen-surface tension-reaction, and transverse tension modes. The tensioning unit 1 includes a drive module 11, a moving end module 12, a raising rod 13, a special clamp 14, a screen plate 15, a fixed end module 16, and a receiving trough 17. The drive module 11 is connected to the moving end module 12, the raising rod 13 is fixed to the moving end module 12 and connected to the special clamp 14, and one end of the screen plate 15 is connected to the special clamp 14. The motor 24 drives the drive module 11, which in turn drives the moving end module 12, causing one end of the screen plate 15 to move. The other end of the screen plate 15 is connected to the fixed end module 16 through the special clamp 14 and remains stationary.

[0040] like Figure 2 As shown, the modular reconfigurable tension screening test machine provided by the present invention has the following installation method for the tension and relaxation state of a single screen surface: the tension body unit 1 cooperates with the cover device 4, the cover device 4 is installed around the screen plate 15 of the tension body unit 1, the transparent side plate of the cover device 4 is parallel to the end face of the screen plate and installed at a distance of 1~4mm, and the tension body unit 1 is fixed on the ground.

[0041] like Figure 3 As shown, the modular reconfigurable tension sieve testing machine provided by the present invention is installed in the single-screen tension-reaction mode as follows: a tension body unit 1 is fixed above and below the support 6 and the motor frame 7. The sieve plate 15 of the upper tension body unit 1 is replaced with a blind plate 5 without sieve holes, which overlaps with the outer contour of the projection of the lower sieve plate 15 on the ground. The transparent side plate of the cover device 4 is installed parallel to the end face of the blind plate and the end face of the sieve plate and at a distance of 1~4mm. The support 6 and the motor frame 7 are fixed on the ground.

[0042] like Figure 4As shown, the modular reconfigurable tension screening test machine provided by this invention is installed in the inclined four-screen-surface tension configuration as follows: two tension body units 1 are fixed on the inclined base frame 18, and the distance between the two tension body units 1 is just enough to install a screen plate 15. The moving end module 12 of one of the tension body units 1 is located on the outside, and a fourth screen plate 15 is installed on the moving end module 12. This allows each set of tension body units 1 to drive the movement of two screen plates 15, forming an inclined four-screen-surface tension configuration. A receiving trough 17 is installed below each screen plate. The inclined base frame 18 is fixed to the ground. The transparent side plates of the cover device 4 are fixed to the left and right sides of the screen plate, and the cover plate is fixed directly above the screen plate. The screen plate and the cover plate are supported and fixed to the inclined frame by glass.

[0043] like Figure 5 As shown, the modular reconfigurable tension screening tester provided by the present invention has an inclined four-screen tension-reaction mode installation method that is similar to the inclined four-screen tension mode installation method, except that the single-screen tension mode of the inclined four-screen tension mode is changed to the single-screen tension-reaction mode.

[0044] like Figure 6 As shown, the modular reconfigurable tension screening test machine provided by the present invention is installed in the inclined eight-screen tension form as follows: it is assembled from two sets of inclined four-screen forms. A support frame 9 is installed under the inclined base frame 18 of the first set of inclined four-screen forms to realize the height difference between the two sets of inclined four-screen forms, so that the two sets of inclined four-screen forms are connected end to end. A feed port 3 is installed at the inlet of the raised inclined four-screen form, and a discharge port 8 is installed on the other set.

[0045] like Figure 1 As shown, the modular reconfigurable tension screening tester provided by the present invention has an inclined eight-screen tension-reaction mode installation method that is similar to the inclined eight-screen tension mode, except that the inclined four-screen mode is changed to the inclined four-screen reaction mode.

[0046] like Figure 7 As shown, the modular reconfigurable tension screening test machine provided by the present invention is installed in the transverse tension mode as follows: several screen plates 15 are installed transversely on an extended special clamp 41. In this mode, the tension body unit 1 is rotated 90 degrees relative to other modes and installed. The reciprocating motion direction of the moving end module 12 is perpendicular to the material flow direction and the transparent side plate.

[0047] like Figure 9 The view shows the three-dimensional structure of the assembled support 2, which includes an inclined base 18, a height adjustment rod 19, and an inclined frame 20. The inclined frame 20 is engaged with the inclined base 18 through the height adjustment rod 19, and the inclined base 20 is fixed to the ground.

[0048] like Figure 10The diagram shows a three-dimensional view of the enclosure device 4, which includes transparent side panels 21, a cover plate 22, and glass support rods 23; the two transparent side panels 21 and the cover plate 22 are fixedly installed by the edges of the four glass support rods 23.

[0049] like Figure 11 The diagram shows a perspective view of the drive module 10, which includes a motor 24, a coupling 25, a drive-bearing housing 26, a base plate 27, an adjustable eccentric shaft 28, a drive connecting rod 29, a drive connecting pin 30, and a fixture connector-connecting drive 31. The motor 24 is connected to the adjustable eccentric shaft 28 via the coupling 25. The adjustable eccentric shaft 28 is mounted on the drive-bearing housing 26 and fixed to the base plate 27 to reduce motor vibration. One side of the drive connecting rod 29 is mounted on the adjustable eccentric shaft 28, and the other side is fixed to the fixture connector-connecting drive 31 via the drive connecting pin 30.

[0050] like Figure 12 The mobile terminal module 11 is shown in perspective, including a screen plate clamp base 32, a clamp joint 33, a linear bearing 34, a slide rod 35, a rod seat 36, and a base plate 37. The screen plate clamp base 32 is fixed on the clamp joint 33, the clamp joint 33 is mounted on the linear bearing 34, the slide rod 35 is fixed at both ends on the rod seat 36 and cooperates with the linear bearing 34, and the four rod seats 36 are fixed to the base plate 37.

[0051] like Figure 13 The three-dimensional view of the fixed end module 13 includes a screen plate clamp fixing seat 38, a fixed end column 39, and a fixed end base plate 40; the screen plate clamp fixing seat 38 is engaged with the fixed end base plate 40 through the fixed end column 39.

[0052] The modular reconfigurable tension sieve testing machine provided by this invention achieves its reconfigurability by ensuring that no component of the tension body unit 1 interferes with any extension direction of its sieve plate 15. This allows multiple units to be spliced ​​together in any direction to form a simulated industrial test sieve with ordinary multi-sieve surfaces or transverse multi-sieve surfaces, thus improving its flexibility as a testing device. Furthermore, the tension body unit 1 can be installed in reverse above it to achieve a tension-rebound configuration.

[0053] The driving principle of the modular reconfigurable tension sieve testing machine provided by this invention is as follows: each tension body unit 1 has a separate driving module 11 as a power source. Therefore, when different configurations are formed, the driving parameters of each tension body unit 1 can be adjusted individually, forming a multi-segment, multi-power adjustment of the testing device, which improves its flexibility as a testing device. Specifically, the driving principle of each tension body unit 1 is as follows: the driving module 11 of the tension body unit 1 drives the moving end module 12 to move. The moving end module 12 drives one end of the sieve plate 15 to move through a special clamp 14, while the other end remains fixed, realizing the self-flexion movement of the flexible sieve plate 15. In this way, the material is constantly thrown up and down on the screen plate. The transparent side plates and baffles act as protection to prevent material splashing. In the multi-relaxation screen surface mode, the inclined base frame 18 makes the multiple screen surfaces form an inclined angle. The material on the screen surface is constantly thrown up and down and gradually moves from the high point to the low point of the inclined frame, simulating the real working conditions to move the material. In the multi-relaxation screen surface counterattack mode, the material is constantly colliding between the screen plate 15 and the blind plate 5, which accelerates the deagglomeration speed of the material particles and improves the screening efficiency. In the transverse relaxation mode, the screen plate is placed transversely, and the material movement state is studied by changing the installation method of the screen plate.

[0054] The cover device 4 is used to prevent material from splashing.

[0055] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
