DETAILED DESCRIPTION
[0024] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0025] Example:
[0026] Reference Figure 1 - Figure 6 The utility model discloses a veterinary drug soluble powder screening device, comprising a shell 1, a screening slot 2 penetrating the shell 1 is provided on one side of the top of the shell 1, an inner screening barrel 3 is rotatably arranged in the screening slot 2, an outer screening barrel 4 is sleeved on the outer side of the inner screening barrel 3, a plurality of scrapers 5 for breaking up lumps are fixedly connected to the inner side wall of the outer screening barrel 4 in an annular array, the scraper 5 is in contact with the outer side wall of the inner screening barrel 3 at a side away from the outer screening barrel 4, the inner screening barrel 3 is connected to the side of the outer screening barrel 4 close to the feeding port of the screening slot 2 by a driving member 6, and a discharge slot 7 connected to the screening slot 2 is provided at the bottom of the shell 1.
[0027] In this embodiment, observe Figure 2It can be found that when in use, the veterinary drug soluble powder is put into the screening tank 2 through the feed port, and then the veterinary drug soluble powder contacts the inner screening barrel 3 in the screening tank 2, and then the driving member 6 is started, and the driving member 6 is used to rotate the inner screening barrel 3, so that the veterinary drug soluble powder particles can be efficiently screened, and the veterinary drug soluble powder particles that cannot pass through the inner screening barrel 3 will roll along the inner wall of the inner screening barrel 3, and finally be discharged through the discharge port of the screening tank 2, which is easy for subsequent secondary processing.
[0028] When the inner sieve barrel 3 rotates, some of the larger particles of veterinary drug soluble powder and the agglomerated veterinary drug soluble powder cannot pass through the inner sieve barrel 3, which will cause the veterinary drug soluble powder particles and the agglomerated veterinary drug soluble powder to be stuck on the sieve hole 8, causing the sieve hole 8 to be blocked, affecting the screening efficiency of the veterinary drug soluble powder. Figure 3 It can be found that an outer sieve barrel 4 is arranged on the outer side of the inner sieve barrel 3, and a plurality of scrapers 5 are connected to the inner side wall of the outer sieve barrel 4. When the driving part 6 is running, the outer sieve barrel 4 will keep rotating synchronously with the inner sieve barrel 3, and then the scraper 5 will continue to scrape the surface of the inner sieve barrel 3, so that the scraper 5 can scrape off the veterinary drug soluble powder stuck in the sieve hole 8, which can effectively avoid the blockage of the sieve hole 8 affecting the screening efficiency. When the scraper 5 scrapes the veterinary drug soluble powder agglomerates, because the structure of the veterinary drug soluble powder agglomerates themselves is not stable, the veterinary drug soluble powder agglomerates will be crushed when squeezed by the scraper 5, so that the veterinary drug soluble powder agglomerates are crushed and pass through the sieve hole 8 into the outer sieve barrel 4. Then, after secondary screening by the outer sieve hole 8, the qualified veterinary drug soluble powder will be discharged through the discharge trough 7 at the bottom of the outer sieve barrel 4, so that the qualified particles and unqualified particles of the veterinary drug soluble powder are discharged separately, which is convenient for the subsequent collection and secondary processing of the veterinary drug soluble powder.
[0029] In a further preferred embodiment of the present invention, Figure 3 - Figure 5 As shown, the inner screen barrel 3 and the outer screen barrel 4 are evenly distributed with screen holes 8 for screening, wherein the diameter of the screen holes 8 in the inner screen barrel 3 gradually decreases from the inside to the outside, so that the screen holes 8 are arranged in the inner screen barrel 3 in a constricted shape.
[0030] In this embodiment, by providing sieve holes 8 on the barrel walls of the inner sieve barrel 3 and the outer sieve barrel 4, the veterinary drug soluble powder can be screened in multiple stages, which can improve the quality of the veterinary drug soluble powder after screening. However, since some veterinary drug soluble powders agglomerate, the volume of the veterinary drug soluble powders will increase, which will easily block the sieve holes 8. Moreover, since the agglomerated veterinary drug soluble powders themselves are not connected stably, the agglomerated veterinary drug soluble powders are easily dispersed when subjected to external force. Therefore, the observation Figure 4It can be found that by gradually reducing the diameter of the sieve holes 8 on the inner sieve barrel 3 from the inside to the outside and setting the sieve holes 8 in a constricted shape, the agglomerated veterinary drug soluble powder can enter the sieve holes 8 more easily, so that the agglomerated part of the veterinary drug soluble powder extends out of the inner sieve barrel 3, so that the scraper 5 can break up the agglomerated veterinary drug soluble powder when scraping across the surface of the inner sieve barrel 3, which can effectively prevent the agglomerated veterinary drug soluble powder from being intercepted and discharged by the inner sieve barrel 3 for secondary processing.
[0031] In a further preferred embodiment of the present invention, Figure 5 As shown, the scraper 5 is spirally arranged on the outer side of the inner screen barrel 3 with the axis of the inner screen barrel 3 as a reference, and the screen holes 8 in the outer screen barrel 4 are avoided by the scraper 5.
[0032] In this embodiment, by spirally setting the scraper 5 on the outside of the inner screen barrel 3, it can be avoided that after the scraper 5 breaks up the veterinary drug soluble powder agglomerates, the veterinary drug soluble powder powder directly rolls along the scraper 5 and the inner cylinder wall of the outer screen barrel 4 to the discharge port of the screening trough 2 and is discharged, thereby avoiding qualified veterinary drug soluble powder particles from being mistakenly discharged for secondary processing, thereby effectively improving the screening quality of the screening device.
[0033] In a further preferred embodiment of the present invention, Figure 6 As shown, the driving member 6 includes a motor 61, a gear 62, an inner gear ring 63 and an outer gear ring 64, the inner gear ring 63 and the outer gear ring 64 are respectively connected to the inner screen barrel 3 and the outer screen barrel 4, the inner gear ring 63 and the outer gear ring 64 are meshed and transmitted by the gear 62, and the inner top wall of the screening slot 2 is fixedly connected with a motor 61 for driving the gear 62 to rotate.
[0034] In this embodiment, by setting the inner gear ring 63 and the outer gear ring 64, when the gear 62 rotates, the inner gear ring 63 and the outer gear ring 64 are coaxially reversed, which can increase the rotation speed difference between the inner sieve barrel 3 and the outer sieve barrel 4, and increase the speed at which the scraper 5 scrapes across the surface of the inner sieve barrel 3, thereby improving the efficiency of the scraper 5 in cleaning the sieve holes 8 of the inner sieve barrel 3, reducing the blockage time of the sieve holes 8, and effectively improving the screening efficiency of the soluble powder of veterinary drugs.
[0035] In a further preferred embodiment of the present invention, Figure 2 As shown, a baffle plate 9 is fixedly connected to the discharge port of the screening trough 2, and a gap for discharging materials is reserved between the bottom of the baffle plate 9 and the screening trough 2.
[0036] In this embodiment, the baffle 9 can be used to prevent the veterinary drug soluble powder rolled up when being screened by the inner screen barrel 3 from flying out of the screening slot 2, so as to prevent the veterinary drug soluble powder from flying everywhere, thereby reducing the difficulty of subsequent cleaning. A gap for discharging is left between the bottom of the baffle 9 and the screening slot 2, so that the veterinary drug soluble powder after screening can be discharged through the gap, so that the veterinary drug soluble powder is discharged more concentratedly, and the difficulty of subsequent veterinary drug soluble powder recovery is reduced.
[0037] In a further preferred embodiment of the present invention, Figure 3 As shown, the side of the baffle plate 9 close to the inner screen barrel 3 is provided with three protruding support columns 10 in a circular array with the axis of the inner screen barrel 3 as a reference, and the three support columns 10 are provided with support wheels 11 on the side away from the baffle plate 9, and the outer side wall of the support wheel 11 is in contact with the outer side wall of the inner screen barrel 3 and the inner side wall of the outer screen barrel 4.
[0038] In this embodiment, observe Figure 3 It can be found that there is a gap between the inner screen barrel 3 and the outer screen barrel 4, which will cause the inner screen barrel 3 to sag under the action of gravity and press the scraper 5, thereby increasing the friction when the scraper 5 scrapes the surface of the inner screen barrel 3, thereby increasing the wear between the inner screen barrel 3 and the scraper 5, and reducing the service life of the screening device. Therefore, a support column 10 is provided on the baffle 9, and a support wheel 11 is rotatably connected to the support column 10. The support wheel 11 provides support between the inner screen barrel 3 and the outer screen barrel 4, which can effectively avoid the increase of friction between the scraper 5 and the inner screen barrel 3, thereby increasing the service life of the screening device.
[0039] By providing three groups of support wheels 11 and support columns 10, three-point support can be utilized to form a triangular support between the inner sieve barrel 3 and the outer sieve barrel 4, which can make the inner sieve barrel 3 and the outer sieve barrel 4 more stable.
[0040] In a further preferred embodiment of the present invention, Figure 2 As shown, the feed port of the screening trough 2 is higher than the discharge port, so that the screening trough 2 is tiltedly arranged in the housing 1.
[0041] In this embodiment, by tilting the screening trough 2 in the shell 1 , the veterinary drug soluble powder can fall under the action of gravity while rotating in the inner screening barrel 3 , so that the veterinary drug soluble powder particles intercepted by the inner screening barrel 3 can be discharged from the inner screening barrel 3 .
[0042] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
