Description

Technical Field

[0001] This utility model relates to the field of fertilizer technology, and in particular to a fertilizer filtration device. Background Technology

[0002] Fertilizers are substances that provide one or more essential nutrients for plants, improve soil properties, and enhance soil fertility. During fertilizer production, it is necessary to separate impurities and clumps from the fertilizer to ensure that the fertilizer particles are uniform and pure in order to meet the needs of subsequent application or processing.

[0003] In the prior art, fertilizers are prone to caking during storage or transportation. If they are not broken up, the caking particles will directly enter the filtration stage, clogging the filter screen and reducing filtration efficiency. Furthermore, during the filtration process, the fertilizer accumulated on the filter screen will clog the screen, reducing the continuous operation capacity of the filtration device and affecting production efficiency. Therefore, a fertilizer filtration device is proposed to solve the above-mentioned problems. Utility Model Content

[0004] In order to solve the technical problems in the prior art, where agglomerated particles directly enter the filtration stage, clogging the filter screen, and fertilizer accumulated on the filter screen during the filtration process will clog the filter screen and reduce the continuous operation capacity of the filtration device, this application provides a fertilizer filtration device.

[0005] The present invention discloses a fertilizer filtration device, which includes a frame and a processing mechanism inside the frame. The processing mechanism includes a rotating plate, which breaks up clumps of fertilizer by rotating the plate.

[0006] The frame is equipped with a filtration mechanism, which includes a scraper and a filter screen. The fertilizer on the filter screen is scraped off and collected by the movement of the scraper.

[0007] Preferably, the processing mechanism further includes a processing frame with a through hole, the processing frame being fixedly installed in the top groove of the frame by bolts, and a feed pipe being fixedly connected to the rear surface of the processing frame.

[0008] Through the above technical solution, the treatment frame is fixedly installed to the frame with bolts, which facilitates disassembly. The lower curved surface of the treatment frame has through holes, which allow the broken fertilizer to fall onto the filter screen. The treatment frame is fixedly connected to the feed pipe for easy feeding. The feed pipe is inclined, which helps the fertilizer to enter the treatment frame smoothly under the action of gravity, reducing the risk of blockage. The frame, treatment frame and feed pipe are all made of stainless steel, which is corrosion resistant and easy to clean.

[0009] Preferably, a motor is fixedly mounted on the front surface of the processing frame, and the output shaft of the motor is rotatably connected to the inner wall of the front groove of the processing frame through a bearing.

[0010] The above technical solution involves fixing the processing frame to the motor, and connecting the motor's output shaft to the processing frame via bearings to ensure the stability of the motor's output shaft rotation. The motor model can be a YE3-90L-2 type three-phase asynchronous motor, which needs to be equipped with a frequency converter to adjust the speed to meet the different fertilizer dispersing requirements.

[0011] Preferably, the output shaft of the motor is fixedly installed at one end of the rotating plate, and the rotating plate is rotatably connected to the inner wall of the processing frame through a bearing.

[0012] The above technical solution involves fixing the output shaft of a motor to a rotating plate, driving the plate to rotate. The rotating plate consists of a long plate on one side and segmented short plates on the other. The long plate is used for initial dispersing of fertilizer, suitable for crushing larger pieces of fertilizer. The segmented short plates, through their interval design, further disperse the fertilizer, preventing it from piling up during rotation. The combination of the long plate and the segmented short plates allows for graded dispersing of fertilizer blocks of different sizes, improving dispersing efficiency. The rotating plate can be made of high-strength carbon steel with an anti-corrosion treatment to enhance wear resistance.

[0013] Preferably, the filtration mechanism further includes an electric push rod, which is fixedly installed on the right side surface of the frame. One end of the telescopic rod of the electric push rod is fixedly installed on the right side surface of the scraper, and the slide rod of the scraper is slidably connected to the inner wall of the right side groove of the frame.

[0014] The above technical solution involves fixing the electric push rod to the frame, and then fixing the scraper to the frame via the telescopic rod of the electric push rod. The extension and retraction of the telescopic rod drives the scraper to reciprocate. The scraper is slidably connected to the frame via a sliding rod, ensuring the stability of the scraper's movement. The scraper can be made of polyurethane, which is wear-resistant and causes minimal damage to the filter screen surface. The electric push rod model can be LX600-24, and a controller is required to adjust the stroke and speed of the push rod. Limit switches must also be installed to prevent the scraper from overtraveling.

[0015] Preferably, the filter screen is fixedly installed on the inner side wall of the frame by bolts, and the lower surface of the scraper is in contact with the upper surface of the filter screen.

[0016] With the above technical solution, the filter screen is fixed to the frame with bolts, which makes it easy to disassemble. The filter screen is in contact with the lower surface of the scraper, and it performs the function of classifying fertilizer particles. Small particles are allowed to fall into the collection frame below through the mesh. The filter screen is made of 304 stainless steel wire mesh, and the mesh size can be customized according to the size of the fertilizer particles. It has high strength and corrosion resistance.

[0017] Preferably, the left and right discharge ports of the frame are both fixedly connected to guide frames, and collection frames are placed in the upper outer surface and bottom groove of the frame.

[0018] With the above technical solution, guide frames are fixedly connected to the discharge ports on both sides of the frame. When the scraper moves to the left, it pushes the fertilizer on the filter screen into the collection box on the left through the guide frame on the left. When the scraper moves to the right, it pushes the fertilizer on the filter screen into the collection box on the right through the guide frame on the right. During this process, the particles fall into the collection box below through the mesh of the filter screen. The guide frame is also made of stainless steel, and the collection box is made of high-density polyethylene, which has the characteristics of corrosion resistance, light weight and low cost.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. By setting up a processing mechanism, the clumped fertilizer is broken up. The lower curved surface of the processing frame has through holes, which facilitate the broken fertilizer to fall onto the filter screen. The motor drives the rotating plate to rotate. The rotating plate consists of a long plate on one side and a segmented short plate on the other side. The long plate is used to initially break up the fertilizer, which is suitable for crushing larger pieces of fertilizer. The segmented short plates, through their interval design, further break up the fertilizer, preventing it from accumulating during rotation. This solves the technical problem in the prior art where fertilizer easily clumps up during storage or transportation. If it is not broken up, the clumps will directly enter the filtration stage, clogging the filter screen and reducing filtration efficiency.

[0021] 2. By setting up a filtration mechanism, fertilizer on the filter screen is scraped and collected. The extension and retraction of the electric push rod drives the scraper to reciprocate. When the scraper moves to the left, it pushes the fertilizer on the filter screen into the left collection box through the left guide frame. When the scraper moves to the right, it pushes the fertilizer on the filter screen into the right collection box through the right guide frame. During this process, the particles fall into the collection box below through the filter screen mesh. This solves the technical problem in the prior art where fertilizer accumulated on the filter screen clogs the filter screen during filtration, reducing the continuous operation capacity of the filtration device and affecting production efficiency.

[0029] Reference Figures 1-5 A fertilizer filtration device includes a frame 1, and a processing mechanism is provided inside the frame 1. The processing mechanism includes a rotating plate 4, which breaks up clumps of fertilizer by rotating the plate 4.

[0030] To reduce the risk of clogging, the processing mechanism also includes a processing frame 2 with through holes.

The lower curved surface of the processing frame 2 has through holes, which facilitates the falling of the dispersed fertilizer onto the filter screen 6. The processing frame 2 is fixedly connected to the feed pipe 21 to facilitate feeding. The feed pipe 21 is inclined, which helps the fertilizer to enter the processing frame 2 smoothly under the action of gravity, reducing the risk of clogging. The frame 1, the processing frame 2, and the feed pipe 21 are all made of stainless steel, which is corrosion-resistant and easy to clean.

[0031] To ensure the stability of the rotation of the output shaft of motor 3, motor 3 is fixedly installed on the front surface of processing frame 2. The output shaft of motor 3 is rotatably connected to the inner wall of the front groove of processing frame 2 through bearings. The motor 3 is fixedly installed on processing frame 2 to ensure the stability of the rotation of the output shaft of motor 3. The model of motor 3 can be YE3-90L-2 type three-phase asynchronous motor 3. It needs to be equipped with frequency converter to adjust the speed to meet the needs of different fertilizers.

[0032] To drive the rotating plate 4 to rotate, the output shaft of the motor 3 is fixedly installed at one end of the rotating plate 4. The rotating plate 4 is rotatably connected to the inner wall of the processing frame 2 through bearings. The rotating plate 4 is driven to rotate by the output shaft of the motor 3. The rotating plate 4 consists of a long plate on one side and a segmented short plate on the other side. The long plate is used to initially break up the fertilizer and is suitable for crushing larger pieces of fertilizer. The segmented short plate, through its interval design, further breaks up the fertilizer and prevents the fertilizer from accumulating during rotation. The combination design of the long plate and the segmented short plate can classify and break up fertilizer blocks of different sizes, improving the breaking up efficiency. The rotating plate 4 can be made of high-strength carbon steel with an anti-corrosion treatment to enhance its wear resistance.

[0033] By setting up a processing mechanism, the clumped fertilizer is broken up. The lower curved surface of the processing frame 2 has through holes, which facilitate the broken fertilizer to fall onto the filter screen 6. The motor 3 drives the rotating plate 4 to rotate. The rotating plate 4 consists of a long plate on one side and a segmented short plate on the other side. The long plate is used to initially break up the fertilizer, which is suitable for crushing larger pieces of fertilizer. The segmented short plate, through its interval design, further breaks up the fertilizer, preventing the fertilizer from accumulating during rotation. This solves the technical problem in the prior art where fertilizer is prone to clumping during storage or transportation. If it is not broken up, the clumps will directly enter the filtration stage, clogging the filter screen 6 and reducing the filtration efficiency.

[0034] In order to scrape off and collect the fertilizer on the filter screen 6, a filtration mechanism is provided inside the frame 1. The filtration mechanism includes a scraper 51 and a filter screen 6. The fertilizer on the filter screen 6 is scraped off and collected by the movement of the scraper 51.

[0035] To ensure the stability of the scraper 51's movement, the filtration mechanism also includes an electric push rod 5. The electric push rod 5 is fixedly installed on the right side surface of the frame 1. One end of the telescopic rod of the electric push rod 5 is fixedly installed on the right side surface of the scraper 51. The sliding rod of the scraper 51 is slidably connected to the inner wall of the groove on the right side of the frame 1. The electric push rod 5 is fixedly installed on the frame 1, and the extension and retraction of the telescopic rod drives the scraper 51 to reciprocate. The sliding rod of the scraper 51 is slidably connected to the frame 1, ensuring the stability of the scraper 51's movement. The scraper 51 can be made of polyurethane material, which is wear-resistant and causes little damage to the surface of the filter screen 6. The electric push rod 5 can be an LX600-24 type electric push rod 5, which needs to be equipped with a controller to adjust the stroke and speed of the push rod. At the same time, a limit switch needs to be installed to prevent the scraper 51 from overtraveling.

[0036] To allow small particles to fall through the mesh into the lower collection frame 71, the filter screen 6 is fixedly installed on the inner wall of the frame 1 with bolts. The lower surface of the scraper 51 contacts the upper surface of the filter screen 6. The filter screen 6 is fixedly installed to the frame 1 with bolts, which facilitates disassembly while fixing it. The filter screen 6 performs the function of grading fertilizer particles by contacting the lower surface of the scraper 51, allowing small particles to fall through the mesh into the lower collection frame 71. The filter screen 6 is made of 304 stainless steel wire mesh, and the mesh size can be customized according to the size of the fertilizer particles. It has high strength and corrosion resistance.

[0037] To push the fertilizer on the filter screen 6 into the collection box 71 on the right through the guide frame 7 on the right, the left and right outlets of the frame 1 are both fixedly connected to the guide frame 7. The collection box 71 is placed in the upper outer surface and the bottom groove of the frame 1. The guide frame 7 is fixedly connected to both outlets of the frame 1. When the scraper 51 moves to the left, it pushes the fertilizer on the filter screen 6 into the collection box 71 on the left through the guide frame 7 on the left. When the scraper 51 moves to the right, it pushes the fertilizer on the filter screen 6 into the collection box 71 on the right through the guide frame 7 on the right. During this process, the particles fall into the collection box 71 below through the mesh of the filter screen 6. The guide frame 7 is also made of stainless steel, and the collection box 71 is made of high-density polyethylene, which has the characteristics of corrosion resistance, light weight and low cost.

[0038] By setting up a filtration mechanism, fertilizer on filter screen 6 is scraped off and collected. The extension and retraction of the electric push rod 5 drives scraper 51 to reciprocate. When scraper 51 moves to the left, it pushes the fertilizer on filter screen 6 into collection frame 71 on the left through guide frame 7 on the left. When scraper 51 moves to the right, it pushes the fertilizer on filter screen 6 into collection frame 71 on the right through guide frame 7 on the right. During this process, particles fall into collection frame 71 below through mesh holes of filter screen 6. This solves the technical problem in the prior art where fertilizer accumulated on filter screen 6 clogs filter screen 6 during filtration, reducing the continuous operation capacity of the filtration device and affecting production efficiency.

[0039] Working principle: The staff pours the fertilizer into the processing frame 2 through the inclined feed pipe 21. A material flow sensor can be added at the inlet of the feed pipe 21 to monitor the feed amount in real time and feed the data back to the control system to avoid equipment blockage or damage due to feed overload. Then, the control system starts the motor 3 according to the preset program, drives the rotating plate 4 to rotate at high speed, thereby breaking up the fertilizer. The speed of the motor 3 is adjusted by the frequency converter to meet the breaking up requirements of different types of fertilizer.

[0040] The broken-up fertilizer falls evenly onto the surface of the filter screen 6 through the through holes opened on the arc-shaped surface at the lower end of the processing frame 2. Small fertilizer particles fall into the collection frame 71 below through the mesh of the filter screen 6, while large fertilizer particles remain on the surface of the filter screen 6.

[0041] During the process of fertilizer dispersing and filtration, the control system starts the electric push rod 5 through the program, which drives the scraper 51 to reciprocate on the surface of the filter screen 6. The controller can precisely adjust the stroke and speed of the push rod, and with the help of the limit switch, prevent the scraper 51 from overtraveling, ensuring safe operation. When the scraper 51 moves to the left, it pushes the large fertilizer particles on the surface of the filter screen 6 into the left collection box 71 along the left guide frame 7. When it moves to the right, it pushes the fertilizer into the right collection box 71 along the right guide frame 7.

[0042] Vibration sensors can be added to the processing frame 2 as needed to monitor the operating status of the rotating plate 4 and prevent abnormal vibration or damage to the equipment due to fertilizer jamming. Pressure sensors can be added below the filter screen 6 to monitor the load of the filter screen 6 in real time and prevent the filter screen 6 from deforming or breaking due to the accumulation of large fertilizer particles.

[0043] The motor bearing 3 needs to be lubricated with lithium-based grease regularly to ensure smooth rotation. The electric push rod 5 slide needs to be lubricated with silicone oil or special lubricant regularly to reduce frictional resistance. The sliding connection of the scraper 51 slide needs to be checked regularly and lubricated to prevent jamming. The rotating plate bearing 4 needs to be checked once a quarter and lubricated to prevent wear.

[0044] Regularly check if the filter screen 6 is clogged. If it is, disassemble it for cleaning or replacement. Check if the scraper 51 is worn. Replace it if necessary. Regularly check if the bolts are loose and if the stainless steel surface is corroded. Tighten or perform anti-corrosion treatment if necessary.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
