Description

Technical Field

[0001] The present application relates to the technical field of peristaltic pumps, and in particular to a simple pulse removal device. Background Art

[0002] Peristaltic pumps are commonly used to transport fluids during the continuous wet granulation of solid preparations. They are devices with controllable flow rates. The peristaltic pump produces flow output by intermittently and alternately squeezing the peristaltic pump tube through the rotation of the impeller. However, liquid backsucking occurs instantly after each squeezing and delivery, causing peristaltic pump delivery pulses. Especially when the peristaltic pump output tube is connected to a small-caliber nozzle, the pulse effect is more obvious. In the process of continuous wet granulation of solid preparations, liquids are transported by peristaltic pumps. Due to the influence of pulses, the liquid-to-solid ratio fluctuates during the granulation process, affecting the uniformity and consistency of the granulation.

[0003] In the prior art, the solutions to the peristaltic pump pulse flow include: increasing the number of peristaltic pump rollers, increasing the pulse frequency, reducing the pulse wavelength, and using a pulse suppressor. The above methods can effectively reduce the impact of the pulse effect, but there are disadvantages such as increased cost, complex structure, and inconvenient cleaning. Summary of the invention

[0004] In view of the above problems, the present application proposes a simple pulse removal device, which is provided with a manually adjustable tension device in the conveying pipeline of the peristaltic pump slurry to change the diameter of the conveying pipeline to reduce the pulse; the simple pulse removal device is specifically implemented by the following technical solutions:

[0005] A simple pulse removal device comprises: an adjusting column and an adjusting sleeve, wherein the adjusting sleeve is used for being sleeved on a pipeline, an adjusting hole is provided through the side of the adjusting sleeve, the adjusting column is axially displaceably arranged on the adjusting hole, a top block is axially slidably arranged in the adjusting hole, and the lower end of the adjusting column abuts against the upper end of the top block.

[0006] It is further arranged that a limit ring is installed at the outer end of the adjustment hole, and the limit ring is sleeved on the outer periphery of the adjustment column and the two are threadedly matched. Through this arrangement, the limit ring is tightly connected to the adjustment sleeve, making the overall structure stable.

[0007] Further, a first limiting groove is provided at the opening of the adjustment hole, and a first limiting flange matching with the first limiting groove is provided at the outer edge of the limiting ring. Through this arrangement, the limiting ring is flush with the surface of the adjustment sleeve after installation, and the overall appearance is more beautiful.

[0008] It is further configured that a second limiting flange is provided at the upper end of the top block, and a third limiting flange is provided at the inner end of the adjustment hole and forms an axial limiting cooperation with the second limiting flange. Through this configuration, the axial displacement of the top block is limited, and the overall structure is more stable and efficient.

[0009] It is further provided that a spring is provided between the second limiting flange and the third limiting flange, and the spring is sleeved on the outer circumference of the top block. Through this provision, the adjusting column can prevent the top block from squeezing the pipeline when it is relaxed.

[0010] It is further arranged that a limiting protrusion is arranged on the lower surface of the second limiting flange, and the spring and the limiting protrusion form a limiting cooperation. Through this arrangement, a limiting effect is exerted on the spring, making the overall structure more stable.

[0011] It is further provided that a groove is provided on the upper end surface of the top block, and the groove is matched with the lower end of the adjusting column. Through this provision, the abutment between the top block and the adjusting column is more stable, and the overall structure is more stable.

[0012] It is further provided that a rubber pad is provided at the lower end of the top block, and the rubber pad is mortised with a mounting block on the rubber pad through a mounting groove provided at the lower end of the top block. This arrangement prevents the top block from causing wear and damage to the extruded pipeline.

[0013] In summary, the simple pulse removal device is provided with a manually adjustable tension device in the peristaltic pump slurry delivery pipeline, thereby changing the diameter of the delivery pipeline to achieve the effect of reducing pulses. BRIEF DESCRIPTION OF THE DRAWINGS

It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] The present application is further described with reference to the accompanying drawings and specific implementation methods:

[0022] Please also read Figure 1 to Figure 2 A simple pulse removal device comprises: an adjusting column 1 and an adjusting sleeve 2, wherein the adjusting sleeve 2 is used to be sleeved on a pipeline 3, an adjusting hole 4 is provided through the side of the adjusting sleeve 2, the adjusting column 1 is axially displaceably arranged on the adjusting hole 4, a top block 5 is axially slidably arranged in the adjusting hole 4, and the lower end of the adjusting column 1 abuts against the upper end of the top block 5.

[0023] See also Figure 1 and Figure 2In this embodiment, a limiting ring 6 is installed at the outer end of the adjusting hole 4, and the limiting ring 6 is sleeved on the outer periphery of the adjusting column 1 and the two are threadedly matched. In addition, the limiting ring 6 can also be connected to the adjusting hole 4 on the adjusting sleeve 2 by abutting or setting limiting ribs; The adjusting hole 4 is provided with a first limiting groove 7 at the opening, and the outer edge of the limiting ring 6 is provided with a first limiting flange 8 which matches the first limiting groove 7. With such a configuration, the outer edge of the limiting ring 6 is inserted into the adjusting sleeve 2, so that the outer surface of the adjusting sleeve 2 has no protrusions, which is not only more beautiful as a whole, but also helpful for the installation connection between the two. The upper end of the top block 5 is provided with a second limiting flange 9, and the inner end of the adjusting hole 4 is provided with a third limiting flange 10 which forms an axial limiting cooperation with the second limiting flange 9. The second limiting flange 9 and the third limiting flange 10 are provided in such a manner that the top block 5 can slide axially in the cavity formed by the limiting ring 6 and the third limiting flange 10. When the adjusting column 1 is adjusted downward, the top block 5 is pushed to move downward to apply pressure to the pipeline 3, so that the diameter of the pipeline 3 becomes smaller, thereby achieving the effect of eliminating pulses. A spring 11 is arranged between the second limiting flange 9 and the third limiting flange 10, and the spring 11 is sleeved on the outer periphery of the top block 5. In this arrangement, when the adjusting column 1 does not apply pressure to the top block 5, the top block 5 will not move downward due to neutrality, thereby applying unnecessary pressure to the pipeline 3, and the setting of the spring 11 enables the top block 5 to always receive a force away from the pipeline 3; a limiting protrusion 12 is arranged on the lower surface of the second limiting flange 9, and the spring 11 and the limiting protrusion 12 form a limiting fit. In this arrangement, the position of the spring 11 can be fixed. In addition, the groove 13 matched with the spring 11 can also play a limiting role; A groove 13 is provided on the upper end surface of the top block 5, and the groove 13 is matched with the lower end of the adjusting column 1. Such an arrangement makes the stroke of the adjusting column 1 when pushing the top block 5 more stable, and the overall structure is more stable; a rubber pad 14 is provided at the lower end of the top block 5, and the rubber pad 14 is mortise-jointed by a mounting groove 15 provided at the lower end of the top block 5 and a mounting block 16 on the rubber pad 14. Such an arrangement makes the top block 5 contact with the pipeline 3 through the rubber when pressing the pipeline 3, thereby preventing the pipeline 3 from being damaged by wear caused by the metal of the top block 5.

[0024] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
