[0002] Water-soluble fertilizer is a kind of fertilizer that dissolves in water and is widely used in agricultural production. It can be quickly absorbed by plants, improve the utilization rate of fertilizers, and promote plant growth. However, in the production process of water-soluble fertilizers, filtration is crucial. Effective filtration can ensure the purity of water-soluble fertilizers, prevent impurities from affecting fertilizer efficiency, and ensure the stability of product quality.

[0003] There are some defects in the water-soluble fertilizer production filtration device in the prior art. First, the traditional filtration device requires manual cleaning of the residues and impurities accumulated on the filter net, which is not only time-consuming and labor-intensive, but also easily affects the production efficiency. Secondly, the filter net is easily clogged by the deposits, resulting in a decrease in the filtration effect and even affecting the normal operation of the entire device. In addition, the existing filtration device lacks an effective automated cleaning mechanism during the filtration operation, resulting in the filter holes being easily clogged after the device has been running for a long time, affecting the filtration effect and the purity of the water-soluble fertilizer.

[0028] like Figure 1-4 As shown, the utility model provides a technical solution: a water-soluble fertilizer production filtering device, comprising: a box body 1, a stirring mechanism 2 is connected to one side of the inner wall of the box body 1, a first filter screen 3 is connected to one side of the inner wall of the box body 1, a scraper mechanism 4 is slidably connected to the outer wall of the upper end of the first filter screen 3, the scraper mechanism 4 includes a scraper body 41, both sides of the outer wall of the scraper body 41 are fixedly connected to a slider 42, the bottom end of the scraper body 41 is movably connected to a spring block 43, the outer wall of one side of the scraper mechanism 4 is connected to a reset spring 5, the side of the scraper mechanism 4 away from the reset spring 5 is connected to a stretching belt 6, one side of the stretching belt 6 is connected to a connecting block 7, and the end of the stretching belt 6 away from the scraper mechanism 4 is connected A motor 8 is connected, and an outer wall on one side of the motor 8 is fixedly connected to an outer wall on one side of the box body 1. A first limit plate 9 is fixedly connected to the outer walls on both sides of the upper end of the first filter screen 3. A slide groove 10 is provided on the outer wall on one side of the first limit plate 9. A slider 42 connected to the side wall of the scraper body 41 is slidably connected to the inner wall of the slide groove 10 provided on the outer wall on one side of the first limit plate 9. A first discharge groove 11 is provided on the outer wall on one side of the box body 1. The connecting block 7 is fixedly connected to the side wall of the first discharge groove 11 provided on the outer wall on one side of the box body 1. A first storage box 12 is connected to the outer wall on one side of the box body 1. The first storage box 12 connected to the outer wall on one side of the box body 1 is correspondingly connected to the first discharge groove 11 provided on the outer wall on one side of the box body 1.

[0029] In the present embodiment, a box body 1 is designed, wherein a stirring mechanism 2 is connected to one side of the inner wall of the box body 1, and the water-soluble fertilizer can be first placed in the stirring mechanism 2, and then stirred by the stirring mechanism 2 and pushed to the first filter screen 3 provided on the inner wall of the box body 1. At this time, a plurality of holes are provided on the first filter screen 3, and the diameter thereof is relatively large, so that the water-soluble fertilizer can be coarsely filtered, and those water-soluble fertilizers that are not dissolved can be isolated. At this time, these large particles of water-soluble fertilizer will accumulate on the outer wall of the upper end of the first filter screen 3. If they are not cleaned in time, the holes on the first filter screen 3 will be blocked, and thus the water-soluble fertilizer cannot be used normally. Therefore, a scraper mechanism 4 is provided at the upper end of the first filter screen 3, wherein the scraper mechanism 4 includes a scraper body 41, and the scraper body 41 can be The outer wall of the upper end of the filter screen 3 slides, so that the water-soluble fertilizer on the first filter screen 3 is scraped off to one end, and the water-soluble fertilizer blocked in the holes of the first filter screen 3 can be removed by the spring block 43 provided at the lower end of the scraper body 41, wherein the spring block 43 corresponds to the size of the hole, and the spring block 43 can be retracted into the scraper body 41, and the scraper body 41 is built with a mounting groove and a spring piece, which can make the spring block 43 repeatedly retracted and ejected, and the outer wall of the spring block 43 is chamfered and can be connected correspondingly to the hole. Therefore, when the scraper body 41 slides on the outer wall of the first filter screen 3, when it reaches the outer wall of the first filter screen 3, the spring block 43 will retract into the scraper body 41, and when it reaches the hole position, the spring block 43 will be ejected by the internal spring piece, thereby The water-soluble fertilizer in the holes on the outer wall of the first filter screen 3 is squeezed out so that it can be used normally. In order to make the scraper body 41 slide smoothly, a stretching belt 6 is connected to one end of the scraper body 41, and the other end of the stretching belt 6 is connected to a motor 8. The motor 8 is arranged on one side of the outer wall of the box body 1, and a return spring 5 is connected to the other side of the scraper body 41.

A first storage box 12 is connected to one side of the outer wall of the box body 1. The first storage box 12 is connected to the first discharge groove 11 accordingly. Therefore, the motor 8 can move the scraper body 41 toward the first discharge groove 11 through the stretching belt 6, and push the water-soluble fertilizer on the first filter screen 3 to the first In the storage box 12, the motor 8 can be turned off at this time, and the stretching belt 6 lacks the pulling force on the scraper body 41. At this time, the reset spring 5 on the other side of the scraper body 41 will reset and exert reverse pulling force on the scraper body 41, so that the scraper body 41 returns to the side of the inner wall of the box body 1. By repeated movement, the water-soluble fertilizer can be better removed. The connecting block 7 can support the stretching belt 6, and the connecting block 7 is cylindrical in shape, which can reduce the friction on the stretching belt 6. The slider 42 connected to one side of the scraper body 41 can be slidably connected to the slide groove 10 opened on one side of the first limit plate 9 connected to the upper end of the side wall of the first filter screen 3, which is enough to limit the sliding of the scraper body 41 without any offset.

[0030] Example 2

[0031] like Figure 1-3 As shown, a second filter screen 13 is fixedly connected to one side of the inner wall of the box body 1, and a second limit plate 14 is fixedly connected to the outer walls on both sides of the upper end of the second filter screen 13. A second discharge groove 15 is opened on the outer wall of one side of the box body 1, and a second storage box 16 is connected to the outer wall of one side of the box body 1. The second storage box 16 connected to the outer wall of one side of the box body 1 is correspondingly connected to the second discharge groove 15 opened on the outer wall of one side of the box body 1, and a collecting plate 17 is fixedly connected to the lower end of the inner wall of the box body 1, and a collecting box 18 is connected to the lower end of the collecting plate 17.

[0032] In this embodiment, a second filter screen 13 is connected to the lower end of the inner wall of the box body 1 by design. The second filter screen 13 is located at the lower end of the first filter screen 3, and the two are correspondingly connected. The second filter screen 13 is also provided with a plurality of holes. Its diameter is smaller than the holes on the first filter 3, so that the water-soluble fertilizer can be finely filtered, and a collecting plate 17 is provided at the lower end of the second filter 13, and a collecting box 18 is provided at the lower end of the collecting plate 17, so that the water-soluble fertilizer that has passed two rounds of filtration can be stored in the collecting box 18, thereby obtaining the required water-soluble fertilizer, and a scraping device is also provided at the upper end of the second filter 13, which can avoid clogging of the second filter 13, and second limiting plates 14 are provided on both sides of the outer wall of the upper end of the second filter 13, which can limit the scraping device, and a second discharge groove 15 is opened on the outer wall of one side of the box body 1, and a second storage box 16 is connected to the outer wall of one side of the box body 1, and the second storage box 16 is correspondingly connected to the second discharge groove 15, so that the scraped water-soluble fertilizer can be stored in the second storage box 16 connecting block 7, so as to carry out subsequent operations.

[0033] Working principle:

[0034] like Figure 1-4As shown, during the transmission and filtering process of the water-soluble fertilizer, the water-soluble fertilizer is pushed into the housing 1 by the stirring of the stirring mechanism 2, and the water-soluble fertilizer will fall on the upper outer wall of the first filter screen 3. After the water-soluble fertilizer is roughly filtered by the first filter screen 3, it falls on the second filter screen 13, and after further filtering by the second filter screen 13, it falls on the collecting plate 17, and finally converges in the collecting box 18 at the bottom to obtain the required water-soluble fertilizer. However, during the filtering process of the first filter screen 3 and the second filter screen 13, the water-soluble fertilizer that has not been filtered will gradually accumulate at its upper end, which will cause the first filter screen 3 and the second filter screen 13 to be blocked over time, making it impossible to use it normally. In order to solve this problem, a scraper body 41 is connected to the upper end of the first filter screen 3, and a stretching belt 6 is connected to one side of the scraper body 41, and the other side of the stretching belt 6 is connected to the motor 8 provided on the outer wall of the housing 1. In addition, first limit plates 9 are connected to both sides of the upper end of the first filter 3, and a chute 10 is provided on one side outer wall of the first limit plate 9. The sliders 42 connected to both sides of the scraper body 41 can be limitedly connected with the inner wall of the chute 10. When the motor 8 drives the stretch belt 6 to pull the scraper body 41 to slide on the upper outer wall of the first filter 3, the water-soluble fertilizer accumulated on the upper outer wall of the first filter 3 can be scraped to the first discharge groove 11 provided on one side of the box body 1, and finally enter the first storage box 12 correspondingly connected to the first discharge groove 11. At the same time, the elastic block 43 connected to the lower end of the scraper body 41 is correspondingly connected to the hole provided at the upper end of the first filter 3, which is used to dredge the hole to prevent blockage. The other side of the scraper body 41 is connected to a return spring 5, and the return spring 5 is fixedly connected to one side of the inner wall of the box body 1. Therefore, the return spring 5 can exert a reverse force on the scraper body 41, and can pull the scraper body 41 back to the side of the inner wall of the box body 1. Therefore, through the interaction between the motor 8 and the return spring 5, the device can better scrape off the water-soluble fertilizer. The same method is applied to the second filter screen 13, that is, through the above operation, the water-soluble fertilizer accumulated on the upper end of the second filter screen 13 is scraped toward the second discharge groove 15 opened on the outer wall of one side of the box body 1, and enters the second storage box 16 corresponding to the second discharge groove 15, thereby completing the filtering operation of the water-soluble fertilizer.
