Description

Technical Field

[0001] The invention relates to the technical field of batching mixer accessories, in particular to an organic water-soluble fertilizer liquid batching device. Background Art

[0002] Organic water-soluble fertilizer is a liquid fertilizer that is a mixture of one or more fertilizers and water. Water-soluble fertilizers are more easily absorbed by vegetation. In the process of batching water-soluble fertilizers, corresponding organic water-soluble fertilizer liquid batching devices are required. Liquid fertilizers, also known as fluid fertilizers, include fertilizers in solution and fertilizers containing suspensions of solid particles. With the advancement of science and technology and the development of society, the characteristics of a single fertilizer often cannot meet the needs of users. Therefore, for compound organic water-soluble fertilizers, multiple types of fertilizer concentrates will be injected and homogenized in conjunction with the batching bin.

[0003] Traditional batching machines are equipped with a stirring function, but there is a problem of uneven mixing during the mixing period, which is prone to precipitation. The precipitated material remains at the bottom of the batching machine for a long time, which will cause cross-contamination. At the same time, after the ingredients are mixed, the material liquid is generally filtered through a pipe filter, which has the problem of organic particles clogging the pipe. If it is not cleaned for a long time, it will still cause cross-contamination. In view of this, we propose an organic water-soluble fertilizer liquid batching device. Summary of the Invention

[0015] As can be seen from the above technical solutions, the organic water-soluble fertilizer liquid batching device provided in the embodiments of this specification has at least the following beneficial effects:

[0016] (1) The present invention drives the air pressure cleaning device to allow gas to be replenished into the cleaning air cavity in one direction, and uses air pressure to automatically discharge the residual fertilizer liquid in the batching hopper. On the other hand, it transmits power to the spiral transmission filter element through the transmission device, causing it to rotate, move and vibrate, and uses multi-directional movement to achieve efficient discharge and cleaning, thereby achieving automatic cleaning of the residual fertilizer liquid in the batching hopper and the filter element at the same time, fully solving the problem of cross contamination caused by residual sediment in the fertilizer liquid.

[0017] (2) The present invention starts the active motor, and the output shaft of the active motor drives the connecting arm on the driving arm through the worm gear to move. The connecting arm is affected by the limited sliding of the piston plate on the connecting seat in the air pressure box, and can only drive the piston plate to continuously move up and down in the air pressure box. During the up and down movement, the piston plate realizes the effect of one-way driving of the gas in the air pressure box. The external air enters the air pressure box from the one-way air inlet valve under the influence of negative pressure, and then squeezes into the cleaning air cavity from the connecting pipe under positive pressure, thereby realizing the effect of automatically unloading the residual fertilizer liquid in the batching hopper by using air pressure.

[0018] (3) The present invention uses a worm to engage a worm wheel, and the worm wheel rotates through a key shaft drive sleeve, and the sleeve drives the spiral transmission filter element on it to move in the limit base.

[0019] (4) The present invention heats the gas in the heating chamber by a heating element. Since the end of the central shaft is fixed to the ferrule, the ferrule slides back and forth on the key shaft under the influence of the sliding shaft on the central shaft, that is, the ferrule moves back and forth synchronously during the rotation. The ferrule drives the air pressure plate to perform piston movement in the heating chamber through the limit rod. During the movement, the air pressure plate squeezes and sucks the gas between the air pressure plate and the one-way flow base, and realizes one-way transportation of the gas through the piston movement. During the gas transportation, the gas is heated in combination with the heating element, and then the heated gas is transported to the hot flow flow chamber, thereby achieving the effect of heating the spiral filter screen in the fertilizer chamber as a whole, and softening the solidified sediment on the spiral filter screen by heating, and further achieving the effect of cleaning the solidified sediment on the filter element.

The bottom of the inclined filter base 8 is fixedly connected with a liquid outlet pipe 11 and a discharge pipe 12 respectively. The output shaft of the stirring motor 4 is connected to a stirring rod. By starting the stirring motor 4, the stirring blade is driven to mix and stir the liquid. After the mixing is completed, the material is discharged into the inclined filter base 8 through the connecting pipe. The fertilizer liquid is spirally filtered layer by layer through the inclined filter base 8 to achieve the effect of multiple filtration. The filtered fertilizer liquid can avoid the problem of sediment affecting the quality of the fertilizer liquid after batching due to uneven mixing during batching. The filtered fertilizer liquid is discharged through the liquid outlet pipe 11. By driving the air pressure cleaning device 7, on the one hand, gas is replenished into the cleaning air cavity 6 in a unidirectional manner, and the air pressure is used to automatically discharge the residual fertilizer liquid in the batching hopper 2. On the other hand, power is transmitted to the spiral transmission filter element 9 through the transmission device 10, so that it rotates, moves and vibrates, and multi-directional movement is used to achieve efficient discharge and cleaning, thereby achieving automatic cleaning of the residual fertilizer liquid in the batching hopper 2 and the filter element at the same time, fully solving the problem of cross contamination caused by residual sediment in the fertilizer liquid.

[0036] In this embodiment, the driving air pressure cleaning device 7 includes an active motor 71 and an air pressure box 76 fixedly installed on the batching machine 1. The end of the active motor 71 is installed on the batching machine 1. The output shaft of the active motor 71 is clamped with a worm 72. The end of the worm 72 is fixedly connected to a driving arm 73. The driving arm 73 is rotatably connected to a connecting arm 74. The end of the connecting arm 74 is rotatably connected to a connecting seat 75. The connecting seat 75 is fixedly connected to a piston plate 77. The top of the air pressure box 76 is respectively fixedly connected to a one-way air intake valve 78 and a connecting pipe 79. The piston plate 77 is connected to the piston of the air pressure box 76, and one end of the connecting pipe 79 is fixedly connected to the material blocking top cover 3 for communicating with the cleaning air chamber 6. A make way groove is provided at the bottom of the air pressure box 76. When the first batch of organic water-soluble fertilizer ingredients is finished, the active motor 71 is started, and the output shaft of the active motor 71 drives the connecting arm 74 on the driving arm 73 through the worm gear 72 to move. The connecting arm 74 is affected by the limited sliding of the piston plate 77 on the connecting seat 75 in the air pressure box 76, and can only drive the piston plate 77 to continuously move up and down in the air pressure box 76. During the up and down movement, the piston plate 77 realizes the effect of one-way driving of the gas in the air pressure box 76. The external air enters the air pressure box 76 through the one-way air inlet valve 78 under the influence of negative pressure, and is then squeezed into the cleaning air chamber 6 from the connecting pipe 79 through the positive pressure, thereby realizing the effect of automatically unloading the residual fertilizer liquid in the batching hopper 2 by using air pressure.

[0037] Furthermore, a heat flow circulation chamber 81, a fertilizer chamber 82, and a heating chamber 83 are respectively provided inside the inclined filter base 8. The inclined filter base 8 is fixedly installed on the batching machine 1. The heating chamber 83 is located in the inclined upper end area of the inclined filter base 8, and the fertilizer chamber 82 is located next to the heating chamber 83. The heat flow circulation chamber 81 is located on the periphery of the heating chamber 83 in the inclined filter base 8. The interior of the fertilizer chamber 82 is located at the two ends of the spiral transmission filter element 9, and the front metal knocking rod 84 and the rear metal knocking rod 85 are fixedly connected. The spiral transmission filter element 9 will collide with the front metal knocking rod 84 and the rear metal knocking rod 85 during the forward and backward movement, and then generate vibration through knocking, thereby promoting the vibration discharge of the sediment blocked on the spiral transmission filter element 9, thereby achieving the effect of automatically cleaning the spiral transmission filter element 9 as a whole, reducing the problem of cross contamination and filter element blockage caused by residual materials.

[0038] Furthermore, the transmission device 10 includes a key shaft 101 and a limit base 106 fixedly installed inside the inclined filter base 8. One end of the key shaft 101 is clamped with a worm gear 102, and the other end of the key shaft 101 is splined with a sleeve 103. The surface of the sleeve 103 is elastically connected to an air pressure plate 104 through a spring. The air pressure plate 104 is fixedly connected to a limit rod 105 on the side close to the key shaft 101. The limit rod 105 slides in the sleeve 103. The interior of the heating chamber 83 is fixedly connected to a one-way flow base 13. The surface of the limit base 106 is fixedly installed with a heating element 107. The surface of the air pressure plate 104 is connected to the inner wall piston of the heating chamber 83. The limit base 106 is fixed to the inside of the heating chamber 83. The surface of the worm gear 102 meshes with the surface of the worm 72. The worm gear 102 drives the ferrule 103 to rotate through the key shaft 101, and the end of the ferrule 103 is fixedly connected to the end of the spiral transmission filter element 9. The ferrule 103 drives the spiral transmission filter element 9 on it to move in the limit base 106. The spiral mesh filter element is used to achieve not only the effect of multi-layer superposition filtering of the fertilizer liquid, but also the characteristics of the spiral shape are used to achieve the effect of automatic material transmission of the spiral transmission filter element 9 during rotation, thereby achieving the purpose of automatic cleaning of the filter element, reducing the problem of cross contamination and filter element clogging caused by residual materials, and realizing transmission through the engagement of the worm gear 102 and the worm 72, thereby achieving the automatic cleaning of the residual fertilizer liquid inside the batching hopper 2 and the filter element at the same time, fully solving the problem of cross contamination caused by residual sediment in the fertilizer liquid.

[0039] The spiral transmission filter element 9 includes a central axis 91, one end of the central axis 91 is fixedly connected to the end of the ferrule 103, and the two end surfaces of the central axis 91 are respectively movably connected inside the inclined filter base 8. A spiral filter screen 92 is fixedly connected to the central axis 91, and the surface of the central axis 91 is located at the two ends of the spiral filter screen 92, which are respectively fixedly connected to the front filter plate 93 and the rear filter plate 94. The spiral filter screen 92 is provided with an inclined guide edge 95. After the fertilizer liquid passes through the spiral filter screen 92 for layer-by-layer filtration, part of the filtered sediment is blocked on the spiral filter screen 92, and part remains between the spirals of the spiral filter screen 92. When the spiral filter screen 92 rotates, the sediment remaining between the spiral filter screens 92 can be spirally transported to the discharge pipe 12 for automatic discharge. The spiral filter screen 92 is provided with an inclined guide edge 95 corresponding to the spiral shape of the spiral filter screen 92, which is an inclined spiral arc surface, which can To avoid the problem of fertilizer liquid remaining between the outer edge of the spiral filter 92 and the inner wall of the fertilizer chamber 82 during normal transportation, and then to avoid the problem of increased sediment residual contamination due to contact dead angles, the surface of the central axis 91 is located at the limit base 106 and is fixedly connected to the sliding shaft 96. The interior of the limit base 106 is respectively fixedly connected to the forward tilting disc 1061 and the rearward tilting disc 1062. The forward tilting disc 1061 and the rearward tilting disc 1062 are in a parallel state. The sliding shaft 96 is movably connected between the forward tilting disc 1061 and the rearward tilting disc 1062. The rotating sliding shaft 96 is affected by the restriction of its surface, which will drive the central axis 91 as a whole to perform a short distance back and forth movement while rotating, that is, the entire spiral filter 92 will also move back and forth during rotation. The power of the back and forth movement is used to assist in unloading the sediment between the spiral filter 92, further improving the effect of the spiral filter 92 automatically removing sediment.

[0040] The heating element 107 heats the gas in the heating chamber 83. Because the end of the central shaft 91 is fixed to the ferrule 103, the ferrule 103 slides back and forth on the key shaft 101 under the influence of the sliding shaft 96 on the central shaft 91, that is, the ferrule 103 moves back and forth synchronously during rotation. The ferrule 103 drives the air pressure plate 104 to perform piston movement in the heating chamber 83 through the limit rod 105. During the movement, the air pressure plate 104 squeezes and sucks the gas between the air pressure plate 104 and the one-way circulation base 13, and realizes one-way transportation of the gas through the piston movement. During the gas transportation, the gas is heated in combination with the heating element 107, and then the heated gas is transported to the hot flow circulation chamber 81, thereby achieving the effect of heating the spiral filter screen 92 in the fertilizer chamber 82 as a whole, and the purpose of softening the solidified sediment on the spiral filter screen 92 is achieved by heating, and further achieving the effect of cleaning the solidified sediment on the filter element. The air pressure plate 104, which is elastically fixed to the ferrule 103 by a spring, automatically replenishes the pressure during the reciprocating extrusion of the gas. The front filter plate 93 and the rear filter plate 94, which move synchronously with the central axis 91, will respectively strike the front metal knocking rod 84 and the rear metal knocking rod 85 during their forward and backward movement, and then generate vibrations through knocking, which promotes the vibration discharge of the miscellaneous oil blocked on the spiral filter 92, the front filter plate 93 and the rear filter plate 94, thereby achieving the effect of automatically cleaning the entire spiral filter 92, eliminating the need for manual replacement of the filter element, and avoiding internal clogging of the filter element due to long-term use.

[0041] It is worth noting that the one-way circulation base 13 includes a fixed base 131, which is fixedly connected to the inside of the heating chamber 83. The side of the fixed base 131 away from the air pressure plate 104 is fixedly connected to the air inlet pipe 132, and the inside of the fixed base 131 is fixedly connected to a one-way valve 133. The end of the one-way valve 133 away from the air pressure plate 104 is fixedly connected to a spiral air pipe 134. The spiral air pipe 134 is sleeved on the outside of the heating element 107, so as to achieve the purpose of fully heating the gas in the spiral air pipe 134 when the heating element 107 is started. At the same time, the spiral air pipe achieves the effect of maximizing the increase of the airflow flow path in a limited space, thereby increasing the heating time of the airflow by the heating element 107 and achieving the effect of sufficient heating. One end of the spiral air pipe 134 away from the one-way valve 133 is fixedly connected to the outlet pipe 135, one end of the air inlet pipe 132 is fixed to the interior of the heat flow circulation cavity 81, and the interior of the air inlet pipe 132 is in circulation with the interior of the heat flow circulation cavity 81, and one end of the air outlet pipe 135 away from the spiral air pipe 134 is fixedly connected to the inclined filter base 8, and the spiral air pipe 134 is in circulation with the interior of the heat flow circulation cavity 81 through the air outlet pipe 135. The hot air replenished in the hot flow circulation cavity 81 can then be returned to the spiral air pipe 134 from the outlet pipe 135 at the lower end of the inclined filter base 8 by using air pressure, thereby achieving the purpose of gas circulation heating.

[0042] When the organic water-soluble fertilizer liquid batching device of the present invention is in use, the organic water-soluble fertilizer is pre-proportioned and put into the batching hopper 2 from the lower hopper 5, and the stirring blade is driven by starting the stirring motor 4 to mix and stir the liquid. After the mixing and batching is completed, the material is discharged to the inclined filter base 8 through the connecting pipe. The fertilizer liquid is spirally filtered layer by layer through the inclined filter base 8 to achieve a multiple filtration effect. The filtered fertilizer liquid can avoid the problem of sediment affecting the quality of the fertilizer liquid after batching due to uneven mixing during batching. The filtered fertilizer liquid is discharged through the liquid outlet pipe 11. When the first batch of organic water-soluble fertilizer ingredients is finished, by starting the active motor 71, the output shaft of the active motor 71 drives the driving arm 73 to move the connecting arm 74 through the worm 72. The connecting arm 74 is affected by the limited sliding of the piston plate 77 on the connecting seat 75 in the air pressure box 76, and can only drive the piston plate 77 to continuously move up and down in the air pressure box 76. During the up and down movement, the piston plate 77 realizes the effect of one-way driving of the gas in the air pressure box 76, and the external air enters from the one-way air inlet valve 78 under the influence of negative pressure. The air pressure box 76 is then squeezed into the cleaning air cavity 6 from the connecting pipe 79 by positive pressure. The cleaning air cavity 6 is provided with air outlets on the four sides of the bottom surface of the material retaining top cover 3. The air outlets are aligned with the four walls inside the batching hopper 2, thereby realizing the effect of automatically unloading the residual fertilizer liquid in the batching hopper 2 by using air pressure. At the same time, the worm 72 engages the worm gear 102, and the worm gear 102 drives the card sleeve 103 to rotate through the key shaft 101. The card sleeve 103 drives the central shaft 91 fixed thereon to rotate as a whole, and the central shaft 91 drives the spiral filter 9 fixed thereon During the rotation, the residual sediment between the spiral filter screens 92 is spirally conveyed and discharged. While discharging and cleaning, the sliding shaft 96 fixed on the central shaft 91 slides between the forward tilting plate 1061 and the rearward tilting plate 1062. The forward tilting plate 1061 and the rearward tilting plate 1062 are in an inclined and parallel state. The rotating sliding shaft 96 is affected by the restriction of its surface inclination, which will drive the central shaft 91 as a whole to move back and forth for a short distance while rotating. That is, the entire spiral filter screen 92 will also move back and forth during the rotation. As a result, the efficiency of automatic discharge and cleaning of sediments between the spiral filter screens 92 is improved by utilizing the forward and backward movement effect, and the front filter screen plate 93 and the rear filter screen plate 94 that move synchronously with the central axis 91 will respectively hit the front metal knocking rod 84 and the rear metal knocking rod 85 during the forward and backward movement, and then generate vibrations through knocking, thereby promoting the vibration discharge of sediments blocked on the spiral transmission filter element 9, thereby achieving the effect of automatic cleaning of the spiral transmission filter element 9 as a whole, and reducing the problems of cross contamination and filter element blockage caused by residual materials.The heating element 107 heats the gas in the heating chamber 83. Because the end of the central shaft 91 is fixed to the ferrule 103, the ferrule 103 slides back and forth on the key shaft 101 under the influence of the sliding shaft 96 on the central shaft 91, that is, the ferrule 103 moves back and forth synchronously during the rotation. The ferrule 103 drives the air pressure plate 104 to perform piston motion in the heating chamber 83 through the limit rod 105. During the movement, the air pressure plate 104 squeezes and sucks the gas between the air pressure plate 104 and the one-way flow base 13, and realizes the one-way flow of gas through the piston motion. During gas transportation, the gas is heated in combination with the heating element 107, and the heated gas is transported to the hot flow circulation chamber 81, thereby achieving the effect of heating the spiral filter screen 92 in the fertilizer chamber 82 as a whole, and softening the solidified sediment on the spiral filter screen 92 by heating, and further achieving the effect of cleaning the solidified sediment on the filter element, and the hot gas replenished in the hot flow circulation chamber 81 is then refluxed from the outlet pipe 135 at the lower end of the inclined filter base 8 to the spiral air pipe 134 by air pressure, thereby achieving the purpose of gas circulation heating.
