DETAILED DESCRIPTION

[0036] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0038] In the description of the invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, welding, riveting, bonding, etc., or a detachable connection, threaded connection, key connection, pin connection, etc., or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] like Figure 1-6 As shown, a chemical raw material testing equipment proposed by the present invention comprises a fixed base 17, a placement base 6 and a storage tube 5. A plurality of mounting slots 7 are spaced apart on the front side of the fixed base 17. The placement base 6 is located inside the mounting slots 7. A mounting shell 13 matching the plurality of mounting slots 7 is provided on the rear end face of the fixed base 17. The mounting shell 13 is communicated with the inside of the mounting slots 7 matching therewith. The mounting shell 13 is connected to the placement base 6 through a forward and backward moving component. The storage tube 5 is located above the placement base 6. The upper end face of the mounting shell 13 is connected to the lifting component through a support block 12. The lifting end of the lifting component is connected to a limiting plate 3. The outer end face of the storage tube 5 is sleeved with the upper end of a mounting ring 4. The limiting plate 3 abuts against the upper end face of the mounting ring 4. A pressing component is provided at the upper opening of the mounting ring 4. A feeding component and a feeding component are spaced apart at the bottom of the storage tube 5. A placement component is provided on the rear end face of the support block 12. The placement component matches the pressing component.

[0040] In the present invention, the chemical raw material testing equipment and the method of using the same, when installing the storage tube 5, first place it on the placement base 6, then drive the placement base 6 to move to the inside of the installation slot 7 through the forward and backward moving components, and finally drive the limit plate 3 to descend through the lifting component and abut against the installation ring 4, so that the storage tube 5 can be limited; when the storage tube 5 needs to be removed, first drive the limit plate 3 to rise through the lifting component, and then drive the placement base 6 to move to the front side of the installation slot 7 through the forward and backward moving components, so that the staff only needs to perform simple operations to complete the installation or disassembly of the equipment without the need for additional adjustments.

[0041] In an optional embodiment, the forward and backward moving assembly includes an electric push rod 15, the bottom of the placement base 6 contacts the inner bottom wall of the installation slot 7, and the rear inner wall of the installation shell 13 is connected to the placement base 6 through the electric push rod 15; when the electric push rod 15 is working, it can push the placement base 6 to move forward and backward in the installation slot 7 of the fixed base 17. Since the bottom of the placement base 6 contacts the inner bottom wall of the installation slot 7, this movement is stable and controllable.

[0042] It should be noted that the electric push rod 15 provides precise position control to ensure that the placement base 6 can be accurately moved to a predetermined position; in addition, since the placement base 6 can be moved forward and backward, its relative position with the storage tube 5 can be conveniently adjusted.

[0043] In an optional embodiment, the lifting assembly includes a driving motor 8, a threaded rod 9, a lifting block 10 and a lifting shell 26. This design realizes the lifting and lowering control of the limit plate 3 through mechanical transmission, thereby facilitating the fixing and disassembly of the mounting ring 4 above the storage tube 5. The lifting shell 26 is arranged on the upper end surface of the support block 12 to provide stable support for the entire lifting assembly. The driving motor 8 is arranged on the upper end surface of the lifting shell 26 as a power source for the lifting action. One end of the threaded rod 9 is rotatably connected to the inner bottom wall of the lifting shell 26 to ensure the stable rotation of the threaded rod 9. The other end of the threaded rod 9 passes through the upper end surface of the lifting shell 26 and is coaxially connected to the output end of the driving motor 8 through a coupling. The lifting block 10 is sleeved on the outer end surface of the threaded rod 9 threadedly connected to it. The lifting block 10 passes through the outer end surface of the lifting shell 26 and is connected to the limit plate 3.

[0044] It should be noted that when the threaded rod 9 rotates, due to the effect of the thread, the lifting block 10 will move up and down along the axial direction of the threaded rod 9. This design utilizes the principle of thread transmission to achieve the smooth lifting of the lifting block 10; the lifting block 10 passes through the outer end surface of the lifting shell 26 and is connected to the limit plate 3, so the lifting movement of the lifting block 10 will directly drive the lifting of the limit plate 3. When it is necessary to fix the storage tube 5 and the mounting ring 4 above it, the drive motor 8 drives the threaded rod 9 to rotate, so that the lifting block 10 and the limit plate 3 are lowered until the limit plate 3 abuts against the upper end surface of the mounting ring 4 to achieve fixation. Conversely, when it is necessary not to fix the storage tube 5, the drive motor 8 can drive the threaded rod 9 to rotate in the opposite direction, so that the lifting block 10 and the limit plate 3 rise, and the fixing of the mounting ring 4 is released.

[0045] In an optional embodiment, the pressing assembly includes a pressing plate 21, a mounting block 20 and a pressing piece. The upper part of the inner end surface of the storage tube 5 is connected to the pressing plate 21. The pressing plate 21 is adapted to the inner end surface of the storage tube 5. The mounting block 20 is coaxially connected to the upper end surface of the pressing plate 21. The pressing piece is detachably connected to the upper part of the pressing plate 21.

[0046] It should be noted that, firstly, the lower pressure plate 21 is cleverly designed to match the shape of the inner end face of the storage tube 5, thus ensuring that the lower pressure plate 21 can be firmly connected to the top of the storage tube 5. Secondly, the mounting block 20 is coaxially connected to the upper end face of the lower pressure plate 21, which means that when the mounting block 20 is subjected to external force, it can evenly transfer the pressure to the lower pressure plate 21, thereby achieving uniform downward pressure on the chemical raw materials inside the storage tube 5. Finally, the lower pressure piece is detachably connected to the top of the lower pressure plate 21, so that the lower pressure piece can be replaced or adjusted as needed to adapt to chemical raw materials of different specifications and types. At the same time, the detachable connection method also facilitates the maintenance and maintenance of the equipment and extends the service life of the equipment.

[0047] In an optional embodiment, the lower pressure piece includes a pressure plate 1 and a connecting rod 2, one end of the connecting rod 2 is coaxially connected to the pressure plate 1, and the other end of the connecting rod 2 is threadedly connected to the inside of the mounting block 20, and the lower pressure plate 21 contacts the inner end surface of the storage tube 5.

[0048] It should be noted that the connecting rod 2 is the core component of the pressing member, and one end of the connecting rod 2 is coaxially connected to the pressing plate 1 to ensure the uniform transmission of the pressing force. At the other end, the connecting rod 2 is connected to the inside of the mounting block 20 by a threaded connection. This connection method not only ensures the stability of the connection, but also allows the operator to remove the connecting rod 2 from the mounting block 20; at the same time, the pressing plate 21 is in contact with the inner end surface of the storage tube 5; by adjusting the insertion depth of the connecting rod 2, the operator can easily control the position of the pressing plate 1, thereby achieving precise pressing of the chemical raw materials.

[0049] In an optional embodiment, the placement assembly includes a placement plate 11, which is arranged on the rear end surface of the support block 12. A mounting hole 14 is vertically penetrated through the middle of the placement plate 11, which ensures the stability of the placement plate 11 and optimizes the spatial structure of the overall device.

[0050] It should be noted that a mounting hole 14 is vertically penetrated through the middle of the placement plate 11 for placing the pressing piece.

[0051] In an optional embodiment, limiting rods 18 are provided on both sides of the bottom of the limiting plate 3 , and limiting holes 19 adapted to the limiting rods 18 are vertically penetrated on both sides of the mounting ring 4 , and the limiting rods 18 are inserted into the limiting holes 19 .

[0052] It should be noted that both sides of the mounting ring 4 are vertically penetrated by limiting holes 19 that are compatible with the limiting rods 18. When the limiting rods 18 are inserted into the limiting holes 19, the mounting ring 4 can be firmly fixed on the limiting plate 3, which can effectively prevent the mounting ring 4 from being displaced. The sizes of the limiting rods 18 and the limiting holes 19 are compatible.

[0053] In an optional embodiment, the discharge assembly includes a discharge port 25 and a discharge cover 24 . The discharge port 25 is disposed at the bottom of the storage tube 5 , and the discharge cover 24 is threadedly connected to the bottom of the discharge port 25 .

[0054] It should be noted that the discharge cover 24 is tightly fixed to the bottom of the discharge port 25 by means of a threaded connection. This design not only ensures the sealing of the discharge port and prevents accidental leakage of raw materials when they are not required to be discharged, but also facilitates the operator to quickly and easily disassemble when necessary. By rotating the discharge cover 24, the operator can easily open or close the discharge port 25 to achieve flexible control of the raw materials.

[0055] In an optional embodiment, the feed assembly includes a feed port 22, a feed cover 23 and a plug plate 16, the feed port 22 is arranged at the bottom of the base 6, the feed cover 23 is threadedly connected to the outer end surface of the feed port 22, and the plug plate 16 is arranged on the inner bottom wall of the feed cover 23 and contacts the inner end surface of the feed port 22.

[0056] It should be noted that the feed assembly is mainly composed of a feed port 22, a feed cover 23 and a plug plate 16, which work together to ensure that the chemical raw materials can smoothly and safely enter the interior of the storage tube 5; the feed cover 23 is tightly fixed to the outer end face of the feed port 22 by a threaded connection. This design not only ensures the sealing of the feed port, but also prevents leakage of the raw materials during the addition process; more importantly, the plug plate 16 is arranged on the inner bottom wall of the feed cover 23 and is in close contact with the inner end face of the feed port 22. The presence of the plug plate 16 further enhances the sealing of the feed port, ensuring that the raw materials will not leak out from the gap between the feed port and the feed cover when closed.

[0057] Another technical problem to be solved by the present invention is to provide a chemical raw material testing device and a method for using the same, comprising the following steps:

[0058] 1) When it is necessary to load chemical raw materials and place them, first add the chemical raw materials into the storage tube 5 through the feed port 22 (with the feed assembly facing upwards). After a certain amount of chemical raw materials are loaded, the lower pressure plate 21 is driven by the pressure plate (1), the connecting rod 2 and the mounting block 20 to push into the storage tube 5, thereby reducing the air inside the storage tube 5 and preventing moisture in the air from affecting the chemical raw materials;

[0059] 2) Then rotate the storage tube 5 and place the storage tube 5 above the placement base 6 (with the feeding assembly facing downward), then start the electric push rod 15, which can drive the placement base 6 to move toward the inside of the installation slot 7, and start the drive motor 8, which can drive the threaded rod 9 to rotate. The rotating threaded rod 9 can drive the limit plate 3 to descend through the lifting block 10, so that the bottom of the limit plate 3 abuts against the upper end surface of the installation ring 4, thereby limiting the storage tube 5;

[0060] 3) When the limiting plate 3 is in contact with the mounting ring 4, the limiting rod 18 at the bottom of the limiting plate 3 can be inserted into the limiting hole 19), further improving the limiting effect;

[0061] 4) When the chemical raw materials need to be loaded and discharged, the driving motor 8 is started, and the driving motor 8 can drive the threaded rod 9 to rotate in the opposite direction. The rotating threaded rod 9 can drive the limit plate (3) to rise through the lifting block 10, so that the limit plate 3 and the mounting ring 4 are disconnected;

[0062] 5) Then the electric push rod 15 is started, and the electric push rod 15 can drive the placement base 6 to move forward. When the placement base 6 moves, it can drive the storage tube 5 located above the placement base 6 to move accordingly, so as to facilitate the removal of the storage tube 5;

[0063] 6) Finally, the discharge cover 24 is removed from the discharge port 25, and then the lower pressure plate 21 is pushed toward the inside of the storage tube (5) through the pressure plate 1, the connecting rod 2 and the mounting block 20, so that the chemical raw materials can be discharged through the discharge port 25.

[0064] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. In addition, the appended claims of the present invention are intended to cover all changes and modifications that fall within the scope and boundaries of the appended claims, or the equivalent forms of such scope and boundaries.

After a certain amount of chemical raw materials are loaded, the lower pressure plate (21) is driven by the pressure plate (1), the connecting rod (2) and the mounting block (20) to push into the interior of the storage tube (5), thereby reducing the air inside the storage tube (5) and preventing moisture in the air from affecting the chemical raw materials; 2) Then, the storage tube (5) is rotated and placed on the placement base (6) (with the feed assembly facing downward), and then the electric push rod (15) is started. The electric push rod (15) can drive the placement base (6) to move toward the inside of the installation slot (7), and by starting the drive motor (8), the drive motor (8) can drive the threaded rod (9) to rotate. The rotating threaded rod (9) can drive the limit plate (3) to descend through the lifting block (10), so that the bottom of the limit plate (3) abuts against the upper end surface of the installation ring (4), thereby limiting the storage tube (5); 3) When the limiting plate (3) and the mounting ring (4) are in contact, the limiting rod (18) located at the bottom of the limiting plate (3) can be inserted into the limiting hole (19), thereby further improving the limiting effect; 4) When it is necessary to load chemical raw materials and discharge them, the driving motor (8) is started, and the driving motor (8) can drive the threaded rod (9) to rotate in the opposite direction. The rotating threaded rod (9) can drive the limit plate (3) to rise through the lifting block (10), so that the limit plate (3) and the mounting ring (4) are disconnected; 5) Then, the electric push rod (15) is started, and the electric push rod (15) can drive the placement base (6) to move forward. When the placement base (6) moves, it can drive the storage tube (5) located above the placement base (6) to move accordingly, so as to facilitate the removal of the storage tube (5); 6) Finally, the discharge cover (24) is removed from the discharge port (25), and then the lower pressure plate (21) is pushed toward the inside of the storage tube (5) by the pressure plate (1), the connecting rod (2) and the mounting block (20), so that the chemical raw materials can be discharged through the discharge port (25).
