Description

Technical Field

[0001] The invention relates to the technical field of suspension agent filtering, in particular to a filtering device used for suspension agent production. Background Art

[0002] Suspension concentrate is a kind of solid raw drug that is insoluble or poorly soluble in water, which is dispersed in water through the action of surfactants and other additives to form a uniform and stable suspension system.

[0003] In the production of suspension concentrates, filtration equipment is used to remove unrefined particles, impurities, and agglomerated materials that may be produced during the production process. It can not only remove impurities and ensure product purity, but also improve grinding efficiency, prevent equipment clogging, and optimize the production process.

[0004] In the prior art, the suspension is usually poured into the filtering device at one time, which will lead to uneven local pressure in the filtering device, so that the flow rate and filtering efficiency in the filtering process are different in different areas. This unevenness may cause impurities in some suspensions to fail to be effectively filtered, thereby affecting the stability of product quality. In addition, pouring at one time may also easily cause the suspension to accumulate in the filtering device and cannot be easily effectively filtered through the filter screen. When the filter screen is blocked, the user needs to empty the suspension in the filtering device and then clean the filter screen, which increases the labor intensity and operation complexity. Frequent cleaning of the filter screen will increase equipment downtime, reduce production efficiency, and increase labor costs and maintenance costs.

[0005] Based on this, a filtering device for suspension production is proposed. Summary of the invention

An L-shaped block 27 is slidably connected to the limiting rod 26, and the limiting rod 26 vertically penetrates and is connected to the L-shaped block 27. A return spring 28, a driven rod 23 and a sealing plate 24 are connected to the L-shaped block 27. The other end of the return spring 28 is connected to the outside of the storage barrel 13, and the return spring 28 is sleeved on the limiting rod 26. The sealing plate 24 and the opening at the lower end of the storage barrel 13 fit together. A traction rod 16 is connected between the driven rod 23 and the translation rod 21, and one end of the traction rod 16 is rotatably connected to the driven rod 23, and the other end of the traction rod 16 is rotatably connected to the translation rod 21. A driving mechanism is connected above the base plate 1, and the driving mechanism pushes the connecting frame 8 to reciprocate on the base plate 1.

[0021] Specifically, Figure 1 As shown, a slideway 3 is provided on the bottom plate 1, and the collecting dish 11 is slidably arranged on the slideway 3. By setting the slideway 3 structure, the stability of the collecting dish 11 sliding thereon is improved, and at the same time, the friction force between the structures can also be relied on to make the collecting dish 11 stop horizontally moving after being moved by force.

[0022] Specifically, Figure 4 As shown, a positioning clamp 12 is connected to the outside of the collecting dish 11, a hole 33 is opened on the positioning clamp 12, a side groove 35 is opened on the outside of the connecting frame 8, and the connecting frame 8 is connected to a pin 29 through a spring, and the lower end of the pin 29 is clamped on the hole 33, and the positioning clamp 12 is slidably connected to the side groove 35, wherein the connecting frame 8 and the pin 29 are elastically connected, and the spring is used to stabilize the connection state of the pin 29 clamped on the hole 33, and the connection state between the collecting dish 11 and the connecting frame 8 is stabilized by the structure to avoid separation between the collecting dish 11 and the connecting frame 8 when the structure is moved, thereby improving the firmness of the structural connection, and the spring can give a downward pulling force to the pin 29 when connected, so that the pin 29 is stably clamped on the hole 33.

[0023] Specifically, Figure 4As shown, a connecting frame 10 is connected to the outside of the filter cylinder 9, and one end of the connecting frame 10 is connected to a pin 2 30 through a spring. A hole 2 34 is opened on the connecting frame 8, and one end of the pin 2 30 is clamped on the hole 2 34. One end of the connecting frame 10 is slidably connected to the side groove 35. The connection state between the pin 2 30 and the hole 2 34 can be stabilized by the spring. The spring structure here also plays a role in pulling the pin 2 30 to move into the hole 2 34 to complete the clamping effect between the two structures and stabilize the clamping state of the structure. When the clamping state needs to be canceled later, it is only necessary to pull the pin 2 30, and the spring structure is stretched at this time.

[0024] Specifically, Figure 1 and Figure 3 As shown, a material discharge slope 25 is provided in the storage barrel 13 , and the material discharge slope 25 is provided so that the suspension can flow along the material discharge slope 25 into the top of the sealing plate 24 , so that when the sealing plate 24 is opened later, the suspension can easily fall into the filter barrel 9 .

[0025] Specifically, Figure 1 and Figure 5 As shown, the driving mechanism includes a cylinder 6, a connecting column 4 is connected to the bottom plate 1, and a limiting platform 5 is connected to the connecting column 4. The limiting platform 5 is provided to prevent the cylinder 6 from deflecting horizontally downward, and because the telescopic end of the cylinder 6 is connected to the propulsion block 7 structure, the cylinder 6 can only tilt toward one side of the back plate 2 in a natural state, and the cylinder 6 is rotatably connected to the limiting platform 5, and the telescopic end of the cylinder 6 is connected to the propulsion block 7, and the inclined surface of the propulsion block 7 faces the direction of the trapezoidal block 36. A symmetrical rod 31 is slidably connected to the back plate 2, and one end of the symmetrical rod 31 is connected to the positioning clamp 12, and a vibration spring 32 is connected to the outer side of the symmetrical rod 31, and one end of the vibration spring 32 is fixedly connected to the positioning clamp 12. A trapezoidal block 36 is connected to the outer side of the connecting frame 8, and the inclined surface of the trapezoidal block 36 faces the position of the reset block 20. A horizontal rod 19 is connected to one side of the back plate 2, and one end of the horizontal rod 19 is connected to the reset block 20.

[0026] Specifically, Figure 5 As shown, a group of inclined surfaces are provided on the reset block 20 and the trapezoidal block 36, and two groups of inclined surfaces are provided on the propulsion block 7. The two groups of inclined surfaces on the propulsion block 7 can cooperate with the inclined surfaces on the reset block 20 and the trapezoidal block 36 respectively. The structure of the propulsion block 7 can be driven to deflect by the inclined surface on the reset block 20. Therefore, the inclination angle of the inclined surface on the reset block 20 is different from the inclination angle of the corresponding inclined surface on the propulsion block 7, while the inclination angle of the inclined surface on the trapezoidal block 36 is the same as the inclination angle of the corresponding inclined surface on the propulsion block 7.

[0027] Specifically, Figure 1 and Figure 5As shown, two symmetrical rods 31 are provided, one end of the symmetrical rod 31 is arranged opposite to the deflection block 17, and the two symmetrical rods 31 are parallel to each other and vertically connected to the outside of the positioning clamp 12. The symmetrical rods 31 are used to limit the structure when the connecting frame 8 moves horizontally. During the horizontal movement of the connecting frame 8, the symmetrical rods 31 will not separate from the back plate 2.

[0028] In summary, the filtering device for suspension production provided by the present embodiment, when the suspension needs to be filtered, the suspension is added to the storage barrel 13, and the cylinder 6 structure is started at this time. The operating state of the cylinder 6 structure is reciprocating telescopic motion, and the cylinder 6 is extended to drive the propulsion block 7 to move toward the trapezoidal block 36, and the propulsion block 7 can be used to push the trapezoidal block 36 to move. At this time, the symmetrical rod 31 slides on the back plate 2, and the vibration spring 32 structure is compressed, and one end of the symmetrical rod 31 can push the deflection block 17 to deflect. At this time, the deflection bar 15 is used to deflect and drive the translation rod 21 to slide on the slide 22, and the slide 22 is used to move horizontally to cooperate with the traction rod 16 to push the driven rod 23 to move, and the driven rod 23 overcomes the elastic force of the reset spring 28 to separate the sealing plate 24 from the storage barrel 13. At this time, the suspension placed in the storage barrel 13 can fall into the filter cylinder 9 below. Since the filter cylinder 9 is in a moving state during the material discharge process, the suspended agent dropped at this time can also be well spread in the filter cylinder 9.

[0029] When the push block 7 moves horizontally until it contacts the reset block 20, since the reset block 20 is provided with an inclined surface, when the inclined surface contacts the inclined surface on the push block 7, the push block 7 structure begins to deflect upward, and the push block 7 begins to separate from the trapezoidal block 36. Since the positioning clamp 12 is subjected to the force storage effect of the vibration spring 32, the connecting frame 8 quickly moves away from the back plate 2. In this process, since there is no accumulation of suspending agent above the filter holes covered by impurities, it is beneficial for impurities to separate from the filter holes under the action of inertia, thereby avoiding impurities from clogging the filter screen cylinder 9, further ensuring the stable filtering operation of the suspending agent, and the corresponding symmetrical rod 31 moves away from the deflection block 17. When the reset spring 28 acts, the L-shaped block 27 closes the opening below the storage barrel 13 again. Due to the friction between the collecting dish 11 and the slide 3, the connecting frame 8 stops moving after moving a distance away from the back plate 2. The setting of the connecting column 4 structure can also avoid excessive movement of the connecting frame 8, which causes the symmetrical rod 31 to separate from the back plate 2.

[0030] When the cylinder 6 structure contracts and resets, the inclined surface on the push block 7 contacts the inclined surface on the trapezoidal block 36, so that the push block 7 passes over the trapezoidal block 36 to reset the structure. When the filter cylinder 9 moves horizontally back and forth, the storage cylinder 13 completes one material discharge. During the reciprocating movement of the filter cylinder 9, the suspension can be spread on the filter screen in the filter cylinder 9 to complete the filtering operation. The filtering device can reduce the filtering burden of the filter cylinder 9, improve the filtering efficiency, and ensure the filtering quality of the suspension to the greatest extent.

[0031] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
