Description

Technical Field

[0001] This utility model relates to the field of organic fertilizer processing technology, and in particular to a separation device for water-soluble organic fertilizer. Background Technology

[0002] Water-soluble organic fertilizer is a type of fertilizer that can be completely dissolved in water. It is rich in various nutrients required for plant growth, such as nitrogen, phosphorus, potassium, and trace elements. It is characterized by rapid absorption, high fertilizer efficiency, and easy absorption by plant roots, making it particularly suitable for use in water-saving agricultural technologies such as drip irrigation and sprinkler irrigation.

[0003] In the production of water-soluble organic fertilizers, filtration separation is a widely used technology to remove insoluble substances from liquids, ensuring the purity and efficiency of nutrients in the final product. The filtration process typically involves using screens or filter membranes to trap solid particles while allowing nutrient-rich liquids to pass through for subsequent concentration and processing.

[0004] However, despite the significant advantages of filtration technology in the production of water-soluble organic fertilizers, it also faces some challenges in practical applications. Particularly during long-term operation, filter screens (as part of the filtration equipment used to remove deposits from screens) are prone to clogging. This clogging not only reduces filtration efficiency and leads to decreased processing capacity but also increases energy consumption and maintenance costs. Furthermore, frequent manual cleaning or replacement of filter screens increases operational complexity and downtime, thus affecting the stability and continuity of the entire production line.

[0005] Therefore, developing a device that can effectively reduce filter clogging, improve filtration efficiency, and reduce maintenance requirements is of great significance for optimizing the production process of water-soluble organic fertilizer. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a separation device for water-soluble organic fertilizer.

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0008] A separation device for water-soluble organic fertilizer includes a liquid storage tank with an open upper end, a left support fixed to the left end of the liquid storage tank, a right support fixed to the right end of the liquid storage tank, and a filter assembly rotatably connected to the left and right supports at both ends; and a geared motor driven by the filter assembly via a transmission mechanism; the filter assembly includes a cylindrical filter screen and a support frame fitted onto and fixed to the filter screen; the two ends of the support frame are rotatably connected to the left and right supports respectively; the filter screen has a plurality of filter holes and is arranged in an inclined manner with the left end higher and the right end lower; a collection tank for collecting insoluble matter discharged from the right end of the filter screen is provided at the right end of the liquid storage tank, and a discharge pipe is provided on the collection tank; a drain pipe is provided at the lower part of the liquid storage tank, and a drain valve is provided on the drain pipe.

[0009] Preferably, a left rotating shaft is fixedly connected to the left end of the support frame via a left connecting frame, and the left rotating shaft is connected to the left bracket via a first bearing seat; a right rotating shaft is fixedly connected to the right end of the support frame via a right connecting frame, and the right rotating shaft is connected to the right bracket via a second bearing seat.

[0010] Preferably, the transmission mechanism is a gear transmission mechanism, including a gear ring fixed to the left end of the support frame, and a transmission gear meshing with the gear ring, wherein the transmission gear is fixed to the output shaft of the geared motor.

[0011] Preferably, a mounting plate is fixedly connected to the liquid storage tank, and the geared motor is fixedly connected to the mounting plate.

[0012] Preferably, the left support is provided with a connecting seat, the connecting seat is provided with a liquid inlet pipe, and the right end of the liquid inlet pipe extends into the left end of the filter screen.

[0013] Preferably, an annular baffle is provided at the left end of the support frame.

[0014] Preferably, the support frame includes multiple spaced-apart annular frames and multiple annularly distributed rods fixed to the annular frames.

[0015] Preferably, the filter screen is a split structure and is fixed to the support frame by multiple screws.

[0016] Preferably, the lower end of the liquid storage tank is provided with multiple self-locking wheels.

[0017] The above technical solution has the following advantages:

[0018] The separation device provided by this utility model uses a cylindrical filter screen with an inclined arrangement (higher at the inlet and lower at the outlet). This allows insoluble solids trapped on the filter screen to slide naturally down the surface towards the outlet under the influence of liquid flow and gravity, reducing the risk of accumulation and local blockage. Simultaneously, the filter screen can rotate continuously or intermittently, causing impurities attached to the filter holes to rise to a higher position and automatically detach under gravity, further effectively delaying clogging and ensuring filtration efficiency. Furthermore, the filter screen is entirely in an open space, facilitating high-pressure water flushing or other forms of cleaning of clogged areas from the outside without interrupting equipment operation. This significantly improves maintainability and operational continuity, reduces manual maintenance intensity and downtime. This utility model has significant advantages such as simple structure, stable operation, energy saving, and environmental friendliness. Attached Figure Description

It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other. Example

[0031] As attached Figure 1-8 As shown, a separation device for water-soluble organic fertilizer includes a storage tank 1 with an open upper end, a left support 2 fixed to the left end of the storage tank 1, a right support 3 fixed to the right end of the storage tank 1, and a filter assembly rotatably connected to the left support 2 and the right support 3 at both ends; and a reduction motor 5 driven by the filter assembly through a transmission mechanism 4; the filter assembly includes a cylindrical filter screen 6 and a support frame 7 fitted onto and fixed to the filter screen 6; the two ends of the support frame 7 are rotatably connected to the left support 2 and the right support 3 respectively; the filter screen 6 has a plurality of filter holes 8 and is arranged in an inclined manner with the left end higher and the right end lower; a collection tank 9 for collecting insoluble matter discharged from the right end of the filter screen 6 is provided at the right end of the storage tank 1, and a discharge pipe 10 is provided on the collection tank 9; a drain pipe 11 is provided at the lower part of the storage tank 1, and a drain valve 12 is provided on the drain pipe 11.

[0032] As a specific technical solution in this embodiment, a left rotating shaft 14 is fixedly connected to the left end of the support frame 7 via a left connecting frame 13, and the left rotating shaft 14 is connected to the left bracket 2 via a first bearing seat 15; a right rotating shaft 17 is fixedly connected to the right end of the support frame 7 via a right connecting frame 16, and the right rotating shaft 17 is connected to the right bracket 3 via a second bearing seat 18. This installation method is convenient to maintain and has low rotational resistance.

[0033] As a preferred technical solution in this embodiment, the transmission mechanism 4 is a gear transmission mechanism, including a gear ring 19 fixedly connected to the left end of the support frame 7, and a transmission gear 20 meshing with the gear ring 19. The transmission gear 20 is fixedly connected to the output shaft of the reduction motor 5. The gear transmission mechanism provides stable and reliable transmission. Obviously, the transmission mechanism 4 can also adopt a chain rotation mechanism, etc.

[0034] As a specific technical solution in this embodiment, a mounting plate 21 is fixedly connected to the liquid storage tank 1, and the reduction motor 5 is fixedly connected to the mounting plate 21 to facilitate the maintenance of the reduction motor 5.

[0035] As a preferred embodiment, the left support 2 is provided with a connecting seat 22, and the connecting seat 22 is provided with a liquid inlet pipe 23. The right end of the liquid inlet pipe 23 extends into the left end of the filter screen 6. In use, the liquid inlet pipe 23 is used to introduce the mixture, but obviously other methods can also be used to introduce the mixture.

[0036] As a preferred technical solution in this embodiment, an annular baffle 24 is provided at the left end of the support frame 7, which can reduce the splashing of the mixture from the left end.

[0037] As a specific technical solution in this embodiment, the support frame 7 includes multiple annular frames 25 spaced apart, and multiple rods 26 distributed in a ring and fixedly connected to the annular frames 25.

[0038] As a preferred technical solution in this embodiment, the filter screen 6 has a split structure and is fixed to the support frame 7 by multiple screws 27. The split filter screen 6 is easier to manufacture and assemble, and also easier to maintain.

[0039] The working process of this utility model is as follows: During operation, the organic fertilizer mixture to be filtered is introduced into the filter screen 6 through the inlet pipe 23. Under the action of its own gravity and the inclined arrangement of the filter screen 6, the mixture flows along the inner wall of the cylinder. The soluble components seep out through the filter holes 8 and fall into the bottom of the storage tank 1. Finally, they are discharged through the drain pipe 11 by opening the drain valve 12, thus completing the collection of effective components. The insoluble impurities trapped inside the filter screen 6 slide to the right end with the liquid flow. Under the action of the continuous or intermittent rotation of the filter screen 6, they are further driven to a higher position and fall off by gravity. Finally, they are discharged from the right end into the collection tank 9 and cleaned periodically through the discharge pipe 10. The geared motor 5 drives the support frame 7 through the transmission mechanism 4 to drive the filter screen 6 to rotate slowly, ensuring that the filtration process is continuous and stable. At the same time, the entire structure is designed with an open layout, which facilitates the external high-pressure water flushing of the filter holes during equipment operation to prevent clogging, greatly improving the stability of equipment operation and the convenience of maintenance. Example

[0040] As attached Figure 9As shown, a separation device for water-soluble organic fertilizer is provided with four self-locking wheels 28 at the lower end of the liquid storage tank 1 to facilitate short-distance movement of the separation device. The rest is basically the same as in Embodiment 1.

[0041] This invention sets the filter screen 6 in a cylindrical structure and adopts an inclined arrangement with the inlet end higher and the outlet end lower. This allows insoluble solids trapped on the filter screen 6 to slide naturally down the surface of the filter screen 6 towards the outlet end under the action of liquid flow and gravity, thereby reducing the risk of accumulation and local blockage. At the same time, the filter screen 6 can rotate continuously or intermittently, causing impurities attached to the filter holes 8 to rise to a higher position with the rotation and automatically fall off under gravity, further effectively preventing the filter holes 8 from clogging and ensuring filtration efficiency.
