Abstract
Description
Technical Field
[0001] This utility model relates to the field of acetamiprid production technology, specifically to a crystallization and separation device for the production of acetamiprid technical. Background Technology
[0002] Acetamiprid, as a broad-spectrum and highly effective neonicotinoid insecticide, is widely used in the field of agricultural pest control. It has excellent control effects on aphids, planthoppers and other pests. In the production process of acetamiprid technical, crystallization separation equipment is a crucial link.
[0003] In existing technologies, when crystallization separation equipment is working, its internal rotating drum rotates at extremely high speeds, generating powerful centrifugal force. Under the action of this continuous and powerful centrifugal force, the acetamiprid crystals initially formed in the solution are gradually compressed. These crystals, which were originally relatively loose, begin to approach each other and arrange themselves tightly under the continuous action of centrifugal force, and are gradually compacted. As the centrifugation process continues, the crystals continue to aggregate, eventually forming a dense and hard filter cake on the surface of the filter cloth. Once this filter cake is formed, it adheres tightly to the surface of the filter cloth, with almost no gaps between it and the filter cloth. As the centrifugation time increases, the filter cake layer continues to thicken, and the gaps on the original filter cloth will gradually be blocked by the ever-thickening filter cake. Once blocked, the mother liquor cannot pass through the filter cloth smoothly and be discharged, causing the liquid components in the solution to be unable to separate from the solid crystals in time, which seriously affects the separation effect. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1 - Figure 5This utility model provides an embodiment: a crystallization separation device for the production of acetamiprid technical grade, including a main mounting cylinder 11, a detachable mounting top cover 12 mounted on the main mounting cylinder 11, a fixed bracket 13 fixedly mounted on the main mounting cylinder 11, and a discharge pipe 14. It also includes a separation execution component mounted on the main mounting cylinder 11, a protective cover 21 rotatably connected to the mounting top cover 12, a drive component and a transmission component mounted on the mounting top cover 12, a sliding seat 25 slidably connected to the mounting top cover 12, a mounting bracket 26 mounted on the sliding seat 25, a push plate assembly mounted on the mounting bracket 26, a sliding bracket 27 slidably connected to the mounting bracket 26, and a push roller body 28 rotatably connected to the sliding bracket 27. The sliding seat 25 is connected to the output end of the transmission component.
[0026] The transmission assembly can adjust the position of the sliding seat 25. When the separation execution assembly is working, the push roller body 28 can provide inward squeezing force, and the push plate assembly can provide thrust to the sliding bracket 27.
[0027] Before use, assemble the mounting top cover 12 onto the main mounting cylinder 11. The detachable design of the mounting top cover 12 allows for the removal and replacement of components such as the drive assembly during subsequent use. It can also be adjusted by adjusting the push plate assembly to provide thrust to the sliding bracket 27 as needed. The drive assembly then transmits power through the transmission assembly to move the sliding seat 25 and adjust the position of the mounting bracket 26. This ensures that the push roller body 28 and the corresponding component of the separation execution assembly maintain a safe and suitable working distance, preventing hard collisions between the separation execution assembly and the push roller body 28 when rotating at high speed. The detachable design of the mounting bracket 26 allows for the separate replacement of the mounting bracket 26 and its push plate assembly. After adjustment, open the protective cover 21, place the material into the separation execution assembly, and close the protective cover 21 to complete the overall equipment preparation.
[0028] In subsequent use, the separation execution component operates to centrifuge and crystallize the acetamiprid technical solution. When the separation execution component is operating, the push roller body 28 synchronously provides extrusion pressure to the filter cake formed inside the separation execution component, providing extrusion pressure to the filter cake to prevent the filter cake from gradually compacting and affecting the actual separation effect. The separated filtrate is discharged through the discharge pipe 14 after opening, thus completing the separation work.
[0029] Please see Figure 2 and Figure 4 A further solution based on this embodiment is as follows: a sliding groove for guiding the sliding seat 25 is provided on the mounting top cover 12. The sliding seat 25 is slidably connected to the sliding groove. The sliding groove provides linear guidance for the sliding seat 25, so that it moves along a set path, thereby improving the moving accuracy and stability of the sliding seat 25 and preventing the sliding seat 25 from shifting from the mounting bracket 26.
[0030] Please see Figure 5 A further solution based on this embodiment is as follows: a groove is provided on the mounting bracket 26 to guide the sliding bracket 27. The sliding bracket 27 is slidably connected to the groove. The groove constrains the sliding bracket 27 to move in a straight line, ensuring that the pressure direction of the push roller body 28 is stable and that the pressure is stably applied to the filter cloth body 24.
[0031] Please see Figure 1 - Figure 2 A further solution based on this embodiment is as follows: the separation execution component includes a first motor 22 fixedly installed on the main mounting cylinder 11, a centrifuge cylinder body 23 fixedly connected to the output end of the first motor 22, and a filter cloth body 24 fixedly installed on the centrifuge cylinder body 23. The centrifuge cylinder body 23 is rotatably connected to the main mounting cylinder 11. The first motor 22 drives the centrifuge cylinder body 23 to rotate at high speed, and solid-liquid separation is achieved under the action of centrifugal force, and the liquid is discharged through the filter cloth body 24.
[0032] Please see Figure 1 - Figure 3 A further solution based on this embodiment is as follows: the drive component includes a second motor 29 fixedly mounted on the mounting top cover 12 and a first gear 210 fixedly connected to the output end of the second motor 29. The transmission component is connected to the first gear 210. The second motor 29 drives the first gear 210 to rotate, providing power input to the transmission component. The power transmission is stable and efficient, providing power for the position adjustment of the push roller body 28.
[0033] Please see Figure 1 - Figure 4 A further solution based on this embodiment is as follows: The transmission assembly includes a rotating disk 211 rotatably connected to the mounting top cover 12, a connecting rack 212 fixedly installed on the rotating disk 211, a second gear 213 rotatably connected to the mounting top cover 12, and a fixed toothed plate 214 fixedly installed on the sliding seat 25. The second gear 213 meshes with the connecting rack 212 and the fixed toothed plate 214, and the first gear 210 meshes with the tooth groove of the rotating disk 211. When the first gear 210 rotates, it can drive the rotating disk 211 to rotate. The connecting rack 212 drives the second gear 213 to rotate, and the second gear 213 then drives the fixed toothed plate 214 to move the sliding seat 25, thereby realizing precise displacement adjustment of the sliding seat 25 and adjusting the position of the push roller body 28 to meet the filter cake processing requirements under different working conditions.
[0034] Please see Figure 3 - Figure 4A further solution based on this embodiment is as follows: a rotating groove adapted to the rotating disk 211 is provided on the mounting top cover 12. The rotating disk 211 is rotatably connected to the rotating groove. The rotating groove positions the rotating disk 211 radially and axially to ensure its stable rotation and prevent the rotating disk 211 from tilting, which would affect its gear adjustment accuracy.
[0035] Please see Figure 4 - Figure 5 A further solution based on this embodiment is as follows: the pusher assembly includes an adjusting screw 31 rotatably connected to the mounting bracket 26, a sliding pusher 32 threadedly connected to the adjusting screw 31, and a connecting spring 33 fixedly connected between the sliding pusher 32 and the sliding bracket 27. When the adjusting screw 31 rotates, it can drive the sliding pusher 32 to move along its own axis. The adjusting screw 31 drives the sliding pusher 32 to move, and the connecting spring 33 pushes the sliding bracket 27 to realize the pressure adjustment of the pusher body 28. The pressure can be flexibly adjusted according to production needs, adapting to different production conditions, protecting the integrity of the crystal, and improving the separation effect and applicability.
[0036] Working principle: Before use, the mounting top cover 12 is assembled onto the main mounting cylinder 11. The detachable design of the mounting top cover 12 allows for the replacement of drive components and other parts during subsequent use. Furthermore, as needed, rotating the adjusting screw 31 moves the sliding push plate 32 along the axis of the adjusting screw 31. The sliding push plate 32 pushes the connecting spring 33, which in turn provides thrust to the sliding bracket 27, thereby adjusting the pressure applied to the push roller body 28. Then, the second motor 29 is started, driving the first gear 210 to rotate. The first gear 210 meshes with the tooth groove of the rotating disk 211, causing the rotating disk 211 to rotate stably within the groove. The connecting rack 212 on the rotating disk 211 rotates synchronously, and the connecting rack 212 meshes with the second gear 210. 3. Engagement drives the second gear 213 to rotate, and the second gear 213 then engages with the fixed tooth plate 214, causing the fixed tooth plate 214 and the sliding seat 25 to slide along the slide groove on the mounting top cover 12. The sliding seat 25 drives the mounting bracket 26 to move synchronously, adjusting the position of the mounting bracket 26 so that the push roller body 28 maintains a safe and suitable working distance with the centrifuge cylinder body 23 and the filter cloth body 24, avoiding hard collisions between the centrifuge cylinder body 23 and the filter cloth body 24 when they rotate at high speed. The detachable design of the mounting bracket 26 allows the mounting bracket 26 and its push plate assembly to be replaced separately in the future. After the above adjustment is completed, open the protective cover 21, put the acetamiprid technical solution into the centrifuge cylinder body 23, and close the protective cover 21 to complete the overall equipment preparation work.
[0037] In subsequent use, the first motor 22 is started, which drives the centrifuge body 23 to rotate at high speed. The centrifuge body 23 drives the filter cloth body 24 to rotate synchronously. Under the action of centrifugal force, the acetamiprid technical solution achieves solid-liquid separation. Crystals form a filter cake on the surface of the filter cloth body 24, and the liquid passes through the filter cloth body 24 and is discharged into the inner cavity of the main mounting cylinder 11. During this process, the push plate assembly continuously provides thrust to the sliding support 27. The sliding support 27 slides along the groove on the mounting support 26, driving the push roller body 28 to synchronously and smoothly provide inward squeezing force. The squeezing force of the push roller body 28 acts on the filter cake formed in the centrifuge body 23, applying stable pressure to the filter cake and preventing the filter cake from gradually compacting. After separation is completed, the first motor 22 and the second motor 29 are turned off, and the discharge pipe 14 is opened to discharge the separated filtrate, thus completing the entire crystallization separation of acetamiprid technical.
[0038] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
