Description

Technical Field

[0001] This utility model relates to the field of fertilizer screening technology, and in particular to an anti-clogging filter assembly for liquid calcium fertilizer application. Background Technology

[0002] Liquid calcium fertilizer is prone to crystallization due to temperature changes or standing, and may also contain impurities (such as soil particles and undissolved fertilizer components), causing rapid clogging of the filter and affecting the continuity of fertilization. Therefore, it is necessary to filter and screen the liquid calcium fertilizer during the application process to remove impurities and prevent them from accumulating and causing blockages.

[0003] Existing filtration devices mostly rely on manual disassembly and cleaning after shutdown, or use motor-driven scrapers, which have problems such as high energy consumption, complex mechanical structure, and high maintenance costs.

[0004] A clogging-resistant fertilizer screening device is disclosed in Chinese patent document CN221869183U. This device includes a frame, a hopper, a screen barrel, a drive source, and a cleaning device. The hopper is located at one end of the screen barrel and connected to it. The screen barrel's axis is inclined downwards away from the hopper. The screen barrel has multiple screen holes. The drive source connects to and drives the screen barrel to rotate. The cleaning device includes an outer cleaning component and an inner cleaning component. The outer cleaning component includes an array of cleaning elements on its circumferential surface. A brush roller with multiple cleaning columns is positioned on the outside of a screen barrel. When the screen barrel rotates, the cleaning columns on the side closest to the screen barrel abut against the nearest screen hole. An inner cleaning component is positioned inside the screen barrel and includes a fixed rod with a scraper. When the screen barrel rotates, the scraper abuts against the inner wall of the screen barrel to clean the inner wall. The above application has the effect of efficiently cleaning the screen and improving the fertilizer screening efficiency. However, this anti-clogging fertilizer screening device uses a motor-driven scraper, which has problems such as high energy consumption, complex mechanical structure, and high maintenance costs.

[0005] To address the shortcomings of the existing technology, providing an anti-clogging filter assembly for liquid calcium fertilizer application is a worthwhile research topic. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of existing filtration devices, which mostly rely on manual disassembly and cleaning after shutdown or use motor-driven scrapers, resulting in high energy consumption, complex mechanical structure, and high maintenance costs. This utility model provides an anti-clogging filter assembly for liquid calcium fertilizer application, achieving the desired technical effect.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] A clogging-resistant filter assembly for liquid calcium fertilizer application includes a filter pipe with flanges fixedly connected to both ends. The filter pipe is fixedly connected to the liquid calcium fertilizer application pipe via the flanges. It also includes a filter screen fixedly connected inside the filter pipe, a cleaning mechanism disposed on the surface of the filter screen, and a discharge mechanism disposed on one side of the filter pipe.

[0009] A support plate is fixedly connected inside the filter pipe, and a support column is fixedly connected to the middle of the support plate. The end of the support column is fixedly connected to the center of the filter screen.

[0010] The cleaning mechanism is located on the outside of the support column. The cleaning brush of the cleaning mechanism can pass through the gap between the filter screen and the filter pipe to clean the front surface of the filter screen.

[0011] The filter screen is an arc-shaped arch, and the diameter of the filter screen is smaller than the diameter of the impurity particles in the liquid calcium fertilizer. The arc-shaped arch of the filter screen faces the end where the liquid calcium fertilizer is supplied. Under the action of the arc surface, the waste particles are guided to the edge of the filter screen.

[0012] The outer side of the support column is provided with an annular groove. The cleaning mechanism includes a rotating ring rotatably connected to the annular groove, several rotating fan blades fixedly connected to the outer side of the rotating ring, a connecting ring fixedly connected to the end of the rotating fan blades, and a cleaning brush fixedly connected to one side of the connecting ring. The cleaning device is driven by water flow, does not require additional energy consumption, and has a simple structure and low cost.

[0013] The gap between the filter screen and the inner wall of the filter pipe is adapted to the shape of the connecting ring. The coefficient of friction between the connecting ring and the filter pipe is less than 0.5. The coefficient of friction between the connecting ring and the filter screen is less than 0.5. The rotational torque of the rotating fan blade is transmitted to the cleaning brush through the connecting ring, so that the cleaning brush continuously rotates and brushes the front side of the filter screen.

[0014] The inner brush head of the cleaning brush is shaped to match the front side of the filter.

[0015] The discharge mechanism includes a discharge port on one side of the filter pipe and a closing plate rotatably connected to the end of the discharge port.

[0016] The discharge port is located on the front side of the filter screen, eliminating the need for frequent cleaning of the filter screen assembly, saving labor costs, and making cleaning convenient and quick.

[0017] The discharge port is filled with an absorbent sponge, the shape of which is adapted to the shape of the discharge port, making the treatment of waste particles more convenient and efficient.

[0018] A side plate is fixedly connected to one side of the filter pipe. The bottom height of the side plate is equal to the bottom height of the filter pipe. The side plate is located on the other side of the discharge mechanism to prevent the filter pipe from rotating during use and causing the connection to loosen.

[0019] Positive and beneficial effects:

[0020] 1. This anti-clogging filter assembly for liquid calcium fertilizer application filters waste particles from the liquid calcium fertilizer. Under the action of the arc surface, the waste particles are guided to the edge of the filter and then enter the discharge mechanism. This facilitates the later cleaning and recycling of concentrated waste particles and avoids the situation where waste particles are evenly distributed on the filter surface, causing filter clogging.

[0021] 2. The anti-clogging filter assembly for liquid calcium fertilizer application: When the liquid calcium fertilizer flows through, the water flow drives the rotating fan blades and cleaning brush to rotate, cleaning the surface of the filter screen and keeping the filter screen clean to avoid affecting the flow rate of the liquefied calcium fertilizer. This cleaning device is driven by water flow, does not require additional energy consumption, and has a simple structure and low cost.

[0022] 3. The anti-clogging filter assembly for this liquid calcium fertilizer application allows for easy cleaning of accumulated waste particles by opening the sealing plate after a certain amount of waste particles have accumulated. The waste particles accumulated in the discharge port will not affect the filter assembly, thus eliminating the need for frequent cleaning and saving labor costs. The cleaning process is also convenient and quick. Attached Figure Description

[0032] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0033] Example 1

[0034] like Figures 1 to 8 As shown, an anti-clogging filter assembly for liquid calcium fertilizer application includes a filter pipe 1, with flanges 2 fixedly connected to both ends of the filter pipe 1. The filter pipe 1 is fixedly connected to the liquid calcium fertilizer application pipe through the flanges 2. It also includes a filter screen 3 fixedly connected inside the filter pipe 1, a cleaning mechanism disposed on the surface of the filter screen 3, and a discharge mechanism disposed on one side of the filter pipe 1.

[0035] like Figures 5 to 8 As shown, a support plate 4 is fixedly connected inside the filter pipe 1, a support column 5 is fixedly connected in the middle of the support plate 4, and the end of the support column 5 is fixedly connected to the center of the filter screen 3.

[0036] The cleaning mechanism is located on the outside of the support column 5. By installing a filter screen 3 on the inside of the filter pipe 1, the liquefied calcium fertilizer is filtered to remove particulate impurities, thus preventing particles from accumulating in the pipe and causing blockage. The filter screen 3 is fixed by the support plate 4 and the support column 5, so that the edge of the filter screen 3 does not contact the filter pipe 1. This avoids the accumulation of liquid calcium particles in the gap between the filter screen 3 and the filter pipe 1, which is inconvenient to clean. It also allows the cleaning brush of the cleaning mechanism to pass through the gap between the filter screen 3 and the filter pipe 1 to clean the front surface of the filter screen 3.

[0037] like Figures 3 to 8As shown, filter screen 3 is an arc-shaped arch. The diameter of filter screen 3 is smaller than the diameter of the impurity particles in the liquid calcium fertilizer. The arc-shaped arch surface of filter screen 3 faces the end where the liquid calcium fertilizer is supplied. By setting filter screen 3 to an arc-shaped arch, after filter screen 3 filters the waste particles in the liquid calcium fertilizer, the waste particles are guided to the edge of filter screen 3 by the action of the arc surface, and then enter the discharge mechanism. This facilitates the subsequent cleaning and recycling of the concentrated waste particles and avoids the situation where the waste particles are evenly distributed on the surface of filter screen 3, causing filter screen blockage.

[0038] Example 2

[0039] like Figures 5 to 8 As shown, an annular groove 6 is provided on the outer side of the support column 5. The cleaning mechanism includes a rotating ring 7 rotatably connected to the annular groove 6, several rotating fan blades 8 fixedly connected to the outer side of the rotating ring 7, a connecting ring 9 fixedly connected to the end of the rotating fan blades 8, and a cleaning brush 10 fixedly connected to one side of the connecting ring 9. By setting the rotating fan blades 8 on the support column 5, when the liquid calcium fertilizer flows through, the rotating fan blades 8 and the cleaning brush 10 are driven to rotate under the action of water flow, cleaning the surface of the filter screen 3, keeping the surface of the filter screen 3 clean and avoiding affecting the flow rate of the liquefied calcium fertilizer. This cleaning device is driven by water flow, does not require additional energy consumption, and has a simple structure and low cost.

[0040] Furthermore, by placing the rotating fan blade 8 on the rear side of the filter screen 3, it is possible to prevent the waste particles of liquefied calcium fertilizer from impacting and damaging the fan blade 8. At the same time, the cleaning brush 10 is located on the front side of the filter screen 3 to automatically brush and clean the waste particles attached to the front side of the filter screen 3.

[0041] like Figures 5 to 8 As shown, the gap between the filter screen 3 and the inner wall of the filter pipe 1 is adapted to the shape of the connecting ring 9. The coefficient of friction between the connecting ring 9 and the filter pipe 1 is less than 0.5, and the coefficient of friction between the connecting ring 9 and the filter screen 3 is less than 0.5. By setting the connecting ring 9 between the filter screen 3 and the filter pipe 1, the gap between the filter screen 3 and the filter pipe 1 is filled, so that the space on both sides of the filter screen 3 remains divided. At the same time, the rotational torque of the rotating fan blade 8 is transmitted to the cleaning brush 10 through the connecting ring 9, so that the cleaning brush 10 continuously rotates and brushes the front side of the filter screen 3.

[0042] like Figures 5 to 7 As shown, the inner brush head shape of the cleaning brush 10 is adapted to the front side shape of the filter screen 3. By limiting the shape of the brush head of the cleaning brush 10, it can be adapted to the surface of the filter screen 3, and the arc-shaped surface of the filter screen 3 can be thoroughly cleaned.

[0043] Example 3

[0044] like Figures 1 to 4As shown, the discharge mechanism includes a discharge port 11 opened on one side of the filter pipe 1, and a closing plate 12 rotatably connected to the end of the discharge port 11.

[0045] The discharge port 11 is located on the front side of the filter screen 3. By setting the discharge port 11 inside the filter pipe 1, the filtered and concentrated liquid calcium fertilizer particles are stored in the discharge port 11. The sealing plate 12 is fixedly connected to the discharge port 11 by a locking buckle. When a certain amount of waste particles accumulate, the sealing plate 12 can be opened to clean the accumulated waste particles inside. The waste particles accumulated in the discharge port 11 will not affect the filter screen assembly, so there is no need to clean the filter screen assembly frequently, saving labor costs and making cleaning convenient and quick.

[0046] like Figures 1 to 4 As shown, the inside of the discharge port 11 is filled with an adsorbent sponge 13. The shape of the adsorbent sponge 13 is adapted to the shape of the discharge port 11. By filling the inside of the discharge port 11 with an adsorbent sponge 13, the filtered fertilizer particles can be fixed on the adsorbent sponge 13. When it is necessary to clean the impurities in the discharge port 11, the sealing plate 12 can be opened and the adsorbent sponge 13 can be replaced, making the treatment of concentrated waste particles more convenient and efficient.

[0047] Furthermore, the bottom of the discharge port 11 is sloped, and the bottom height of the side of the discharge port 11 closest to the filter pipe 1 is higher than the bottom height of the other side, so that the filtered waste particles can be concentrated along the slope towards the sponge 13.

[0048] like Figure 2 As shown, a side plate 14 is fixedly connected to one side of the filter pipe 1. The bottom height of the side plate 14 is equal to the bottom height of the filter pipe 1. The side plate 14 is located on the other side of the discharge mechanism. By setting the side plate 14 on one side of the filter pipe 1, it cooperates with the bottom of the discharge port 11 on the other side to support and limit the filter pipe 1, thus preventing the filter pipe 1 from rotating during use and causing the connection to loosen.

[0049] The working principle of this utility model is as follows:

[0050] S1, Filter screen 3 filters out waste particles from the liquid calcium fertilizer;

[0051] S2. Under the action of the arc surface, the waste particles are guided to the edge of the filter screen 3 and then enter the discharge mechanism, which facilitates the later cleaning and recycling of the concentrated waste particles and avoids the situation where the waste particles are evenly distributed on the surface of the filter screen 3, causing the filter screen to become clogged.

[0052] S3. When the liquid calcium fertilizer flows through, the water flow causes the rotating fan blade 8 and cleaning brush 10 to rotate, cleaning the surface of the filter screen 3 and keeping the surface of the filter screen 3 clean to avoid affecting the flow rate of the liquefied calcium fertilizer.

[0053] S4. The filtered fertilizer particles can be fixed on the adsorption sponge 13. When it is necessary to clean the impurities in the discharge port 11, simply open the sealing plate 12 and replace the adsorption sponge 13, making the treatment of concentrated waste particles more convenient and efficient.

[0054] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
