Description

Technical Field

[0001] This invention relates to the field of diatomaceous earth filler production technology, and in particular to a homogenization and mixing preparation apparatus and method for the production of diatomaceous earth filler for mulch film. Background Technology

[0002] Diatomaceous earth filler for agricultural mulch films refers to a functional filler system with diatomaceous earth, a natural porous siliceous mineral, as its main component in the production of agricultural mulch films (especially functional or biodegradable mulch films). It is added to the mulch film matrix through physical blending or surface modification to improve film performance, achieve specific agricultural functions, and reduce raw material costs. Diatomaceous earth filler needs to be mixed with other functional additives and plastic particles during production. This mixing requires a plow mixer. Because diatomaceous earth has an extremely low bulk density, it is a typical "lightweight" powder. Under the action of the plow, it is easily dispersed and suspended in the gas phase space at the top of the cylinder. This results in the heavier plastic particles being effectively mixed at the bottom by the plow, while the lighter diatomaceous earth "floats" to the top, making it difficult to effectively enter the plow's effective area. This results in a macroscopic axial mixing effect that is acceptable, but the radial (vertical) distribution is extremely uneven, failing to meet the homogenization requirements of mulch film filler. Therefore, to address these problems, a homogenization mixing preparation device and method for the production of diatomaceous earth filler for mulch film is proposed. Summary of the Invention

[0033] Example

[0034] like Figures 1-14 As shown, a homogenization and mixing preparation device for the production of diatomaceous earth filler for plastic film includes a frame 3 and a fixed cover 7. The fixed cover 7 is fixedly connected to the top of the frame 3, and a reduction motor 4 is fixedly connected to the top of the frame 3. A drive shaft 5 is fixedly connected to the end of the main shaft of the reduction motor 4. The drive shaft 5 is rotatably connected to the frame 3. Plow blades 6 are fixedly connected to the outside of the drive shaft 5 at intervals. A mixing cylinder 8 is fixedly connected to one end of the frame 3, and the plow blades 6 are located inside the mixing cylinder 8. A floating material lowering mechanism 1 is provided inside the mixing cylinder 8, and a reciprocating mechanism 2 is fixedly connected to one end of the floating material lowering mechanism 1. The plow blade 6 is existing technology, and its specific shape and structure will not be described in detail. First, diatomaceous earth and other materials to be mixed are placed inside the mixing drum 8. Then, the reduction motor 4, through the drive shaft 5, drives the plow blade 6 to stir the materials inside the mixing drum 8. As the drive shaft 5 rotates, the reciprocating mechanism 2 also carries the inner cylinder 119 of the floating material lowering mechanism 1 to the bottom of the mixing drum 8. This allows the floating material to fully re-contact and mix with the other components deposited at the bottom, thus breaking down the stratification barrier mechanistically and ensuring the uniformity of diatomaceous earth filler mixing at both the micro and macro scales. This not only directly guarantees the compositional uniformity and production quality of the final mulch film product, avoiding performance defects caused by uneven filler dispersion, but also significantly optimizes the mixing process, reducing the need for prolonged stirring or repeated operations in traditional processes. Therefore, while improving the mixing effect, it also increases the overall mixing production efficiency.

[0035] The floating material release mechanism 1 is used to guide the material floating on the inner side of the mixing cylinder 8 to the bottom of the mixing cylinder 8; The reciprocating mechanism 2 is used for the up-and-down reciprocating movement of the floating material lowering mechanism 1.

[0036] As a further improvement to the present invention, such as Figure 10 , Figure 11 and Figure 12 As shown, the other end of the fixing block 117 is fixedly connected to an outer cylinder 116, and there are two outer cylinders 116, which are symmetrically arranged on both sides of the vertical center line of the guide ring 118. The outer cylinders 116 are arranged between the rotation paths of adjacent plow blades 6 to ensure that the outer cylinders 116 will not affect the normal operation of the plow blades 6. One end of one of the outer cylinders 116 is fixedly connected to a guide shell 101, and the guide shell 101 is slidably connected to the mixing cylinder 8. The inner side of the outer cylinder 116 is rotatably connected to an inner cylinder 119, and the inner side of the inner cylinder 119 is slidably connected to an air intake shell 121. A filter screen 122 is fixedly connected to the surface of the air intake shell 121. The air intake shell 121 has a hollow structure and an air intake hole is opened on its surface. At the same time, a gap is left between the two outer cylinders 116 for the top rod 123 to move. When adding materials to the inside of the mixing drum 8, the amount added should be such that the outer drum 116 just touches the material after it moves to its lowest position.

[0037] When the outer cylinder 116 is located above the inner side of the mixing cylinder 8, the exhaust fan 127 is started, and the diatomaceous earth floating on the inner side of the mixing cylinder 8 is sucked into the inner cylinder 119 through the suction shell 121 and the filter screen 122; when the outer cylinder 116 moves the inner cylinder 119 down to the top of the material inside the mixing cylinder 8, the inner cylinder 119 will pour the diatomaceous earth into the bottom of the mixing cylinder 8, so that the diatomaceous earth and the bottom material are quickly mixed.

[0038] Furthermore, a vent with a filter plate can be opened at the top of the mixing cylinder 8 to maintain the stability of the air pressure inside the mixing cylinder 8.

[0039] As a further improvement to the present invention, such as Figure 11 , Figure 12 and Figure 14 As shown, a second spring 120 is fixedly connected to the inner side of the inner cylinder 119. The second spring 120 is fixedly connected to the suction shell 121. A top rod 123 is fixedly connected to one end of the suction shell 121, and the end of the top rod 123 is slidably connected to the guide ring 118. The top rod 123 is also slidably connected to the inner cylinder 119. The guide ring 118 includes a transition portion 11801. The second spring 120 provides the suction shell 121 with a spring force that pushes it away from the inner cylinder 119. When the suction shell 121 normally extracts the diatomaceous earth from the floating layer, the top rod 123 is squeezed by the guide ring 118, causing the suction shell 121 to retract into the inner side of the inner cylinder 119 against the spring force of the second spring 120. When it is necessary to pour the diatomaceous earth from the inner cylinder 119 into the mixing cylinder 8, the inner cylinder 119 is rotated 180 degrees counterclockwise inside the outer cylinder 116 so that its opening faces downward. During the rotation, the push rod 123 will suddenly separate from the guide ring 118. At this time, under the elastic force of the second spring 120, the suction shell 121 drives the filter screen 122 to quickly push the diatomaceous earth from the inner cylinder 119 outward. Under the action of inertia, the diatomaceous earth remaining on the surface of the filter screen 122 will also fall off, thus playing an auxiliary role in cleaning the filter screen 122. At this time, the surface of the filter screen 122 and the surface of the inner cylinder 119 are in the same arc surface. During the process of the outer cylinder 116 driving the inner cylinder 119 to move upward, materials such as diatomaceous earth can be prevented from entering the inner side of the inner cylinder 119. When the outer cylinder 116 needs to move the inner cylinder 119 to its initial position, the inner cylinder 119 continues to rotate 180 degrees counterclockwise so that its opening faces upward again. During the rotation, the inner cylinder 119 drives the top rod 123 through the suction shell 121, and gradually fits against the guide ring 118 through the transition part 11801 of the guide ring 118; when the opening of the inner cylinder 119 faces upward, the suction shell 121 retracts back into the inner side of the inner cylinder 119.

[0040] As a further improvement to the present invention, such as Figure 3 and Figure 4 As shown, a rotating cylinder 103 is rotatably connected to the inner bottom of the guide shell 101, and the rotating cylinder 103 is fixedly connected to the inner cylinder 119. A rotary joint 124 is fixedly connected to the inner side of the guide shell 101. The rotating part of the rotary joint 124 is fixedly connected to the rotating cylinder 103, and the rotating part of the rotary joint 124 is connected to the suction shell 121 through an elastic telescopic tube. A material extraction pipe 104 is fixedly connected to the fixed part of the rotary joint 124. The other end of the material extraction pipe 104 is fixedly connected to a main pipe 126. The main pipe 126 is connected to an exhaust fan 127 through an air pipe. The exhaust fan 127 is fixedly connected to the frame 3. The rotary joint 124 is existing technology and is used to ensure that when the inner cylinder 119 rotates, the suction pipe 104 can still normally extract the gas inside the suction shell 121 through the rotary joint 124. When it is necessary to draw the floating layer of diatomaceous earth into the inner cylinder 119 through the suction shell 121 and the filter screen 122, the exhaust fan 127 draws the gas inside the suction shell 121 through the air pipe, the main pipe 126, the suction pipe 104 and the rotary joint 124, thereby realizing the extraction of the floating layer of diatomaceous earth into the inner cylinder 119.

[0041] As a further improvement to the present invention, such as Figure 4 and Figure 7 As shown, a second pulley 105 is rotatably connected to the inner side of the guide shell 101, a first pulley 102 is fixedly connected to the outer side of the rotating drum 103, a belt 128 is sleeved on the outer side of the first pulley 102, and a spur gear 106 is fixedly connected to the second pulley 105 through a connecting shaft. Both sides of the spur gear 106 are provided with drive components. When the inner cylinder 119 needs to rotate counterclockwise, as the guide shell 101 drives the outer cylinder 116 and the inner cylinder 119 to move downward, the drive assembly on the right side will contact the corresponding trigger assembly. Subsequently, the rack 110 on the inner side of the drive assembly meshes with the spur gear 106, causing the spur gear 106 to roll counterclockwise along the right rack 110. The spur gear 106 then drives the inner cylinder 119 to rotate counterclockwise inside the outer cylinder 116 through the second pulley 105, the belt 128, the first pulley 102, and the rotating drum 103. When the spur gear 106 passes over the rack 110, the inner cylinder 119 has just completed a 180-degree rotation.

[0042] When the guide shell 101 drives the outer cylinder 116 and inner cylinder 119 to move upward, the trigger component on the right side will not trigger the right drive component to work. At this time, the inner cylinder 119 temporarily keeps its opening facing downward. When the left drive component passes the left trigger component, its inner rack 110 will mesh with the spur gear 106, causing the spur gear 106 to rotate counterclockwise along the rack 110. Then, the spur gear 106 drives the inner cylinder 119 to rotate counterclockwise inside the outer cylinder 116 through the second pulley 105, belt 128, first pulley 102 and rotating drum 103. When the spur gear 106 passes over the rack 110, the inner cylinder 119 has just completed a 180-degree rotation. At this time, the inner cylinder 119 opens upward, waiting to enter the next round of work.

[0043] As a further improvement to the present invention, such as Figure 6 and Figure 13 As shown, both drive components include a guide rail 129 fixedly connected to the guide housing 101. A fixing plate 108 is slidably connected to the outer side of the guide rail 129. A third spring 130 is sleeved on the outer side of the guide rail 129, and both ends of the third spring 130 are fixedly connected to the guide housing 101 and the fixing plate 108, respectively. A fixing housing 107 is fixedly connected to the other end of the fixing plate 108. A guide shaft 111 is fixedly connected to the inner side of the fixing housing 107. A slider 109 is slidably connected to the outer side of the guide shaft 111. A rack 110 is fixedly connected to one end of the slider 109. A first spring is provided on the outer side of the guide shaft 111. 112, and the two ends of the first spring 112 are fixedly connected to the slider 109 and the fixed shell 107 respectively. The two drive components also include a first interference plate 131 and a second interference plate 132. The first interference plate 131 is fixedly connected to the mixing cylinder 8, and the second interference plate 132 is fixedly connected to the horizontal plate 205 on the inner side of the reciprocating mechanism 2. The first interference plate 131 and the second interference plate 132 respectively resist and interfere with the corresponding fixed plate 108. A trigger component is provided below the two drive components. When the drive component is not in contact with the trigger component, the rack 110 is not meshed with the spur gear 106.

[0044] As a further improvement to the present invention, such as Figure 6 , Figure 8 and Figure 9As shown, both triggering components include a fixed rod 125 fixedly connected to the mixing cylinder 8. The other end of the fixed rod 125 is fixedly connected to a limiting plate 113. One end of the limiting plate 113 is rotatably connected to a guide plate 115. A torsion spring 114 is sleeved on the outer side of the rotating shaft between the limiting plate 113 and the guide plate 115. The limiting plate 113 includes a stop portion 11301. The two triggering components are distributed on one side of the guide shell 101. The left triggering component is close to the spur gear 106, and the right triggering component is close to the mixing cylinder 8. The limiting plate 113 inside the left triggering component is located at the top of the guide plate 115, and the limiting plate 113 inside the right triggering component is located at the bottom of the guide plate 115.

[0045] When the guide shell 101 drives the rack 110 downward via the guide rail 129, the fixing plate 108, the fixing shell 107, the guide shaft 111, and the slider 109, and when the outer cylinder 116 drives the inner cylinder 119 to move down to near the bottom material, the rack 110 on the right side will contact the corresponding guide plate 115. At this time, under the limiting action of the blocking part 11301, the rack 110 will drive the slider 109 to move along the guide shaft 111 towards the spur gear 106; when the rack 110 passes the guide plate 115 and fits against the limiting plate 113, the rack 110 meshes with the spur gear 106, and at the same time, the fixing plate 108 abuts against the first interference plate 131, and the fixing plate 108, the fixing shell 107, the guide shaft 111, the slider 109, and the rack 110 immediately stop moving downward. Subsequently, the guide shell 101 will continue to move downward against the elastic force of the third spring 130, causing the spur gear 106 and the corresponding rack 110 to rotate counterclockwise relative to each other. After the spur gear 106 passes the rack 110, the distance it moves downward is greater than the compression of the third spring 130. When the guide shell 101 returns upward, the third spring 130 resets first, and the corresponding guide plate 115 no longer presses the rack 110. At this time, under the elastic force of the first spring 112, the slider 109, along with the rack 110, separates from the spur gear 106. Therefore, when the guide shell 101 moves upward and resets, the spur gear 106 does not rotate temporarily.

[0046] During the upward movement of the guide shell 101, the rack 110 on the left side will contact the corresponding guide plate 115. Following the same working principle of the spur gear 106 and the corresponding rack 110, the spur gear 106 and the corresponding rack 110 will rotate counterclockwise relative to each other, eventually making the inner cylinder 119 open upward, waiting for the next round of work.

[0047] The reason this device uses mechanical transmission via guide plate 115, limit plate 113, and other related components to drive the engagement and disengagement of spur gear 106 and rack 110, instead of a traditional cylinder, is to improve its applicability. This means that once placed in a factory, the device does not require specially designed air circuits, nor does it need additional air source equipment and control systems, thus significantly reducing installation costs and maintenance complexity. Factory environments often present complex conditions such as high dust and humidity, making pneumatic components prone to failure due to seal aging or air circuit blockage. The purely mechanical transmission structure used in this device offers greater environmental adaptability and operational stability, enabling reliable operation in remote areas or old factories lacking a stable air supply.

[0048] Furthermore, the response characteristics of the mechanical transmission structure naturally synchronize with the reciprocating motion of the guide shell 101. As the guide shell 101 descends, the squeezing action of the guide plate 115 on the rack 110 gradually increases with displacement, and the rotational speed of the spur gear 106 forms a definite proportional relationship with the moving speed of the guide shell 101. This motion coupling characteristic allows the flipping action of the inner cylinder 119 to be completed automatically without additional timing control. In contrast, cylinder drives require precise adjustment of the throttle valve to control the extension and retraction speed, and also need to achieve synchronization with the movement of the guide shell 101 through magnetic switches or position sensors, significantly increasing the design and debugging workload of the control system.

[0049] From a long-term operating cost perspective, the service life of elastic elements such as the third spring 130 and the first spring 112 can typically reach millions of cycles, far exceeding the average lifespan of cylinder seals. When elastic elements fatigue, maintenance personnel can restore function simply by replacing them, whereas cylinder repair often involves troubleshooting the entire pneumatic system, resulting in higher downtime and repair costs. This design choice reflects the optimized balance between reliability and economy in this device, making it particularly suitable for continuous operation scenarios in the production of diatomaceous earth filler for mulch film.

[0050] As a further improvement to the present invention, such as Figure 3As shown, the reciprocating mechanism 2 includes a reciprocating lead screw 203 rotatably connected to the fixed cover 7. A second bevel gear 202 is fixedly connected to the bottom end of the reciprocating lead screw 203. One end of the second bevel gear 202 meshes with a first bevel gear 201, and the first bevel gear 201 is fixedly connected to the transmission shaft 5. A movable plate 204 is helically connected to the outer side of the reciprocating lead screw 203, and the movable plate 204 is slidably connected to the fixed cover 7. The reciprocating lead screw 203 is a bidirectional lead screw, realizing the up-and-down reciprocating motion of the movable plate 204. Movement; A horizontal plate 205 is fixedly connected to the top of the moving plate 204, and the horizontal plate 205 is fixedly connected to the second interference plate 132, the main pipe 126 and the guide shell 101; When the reduction motor 4 drives the transmission shaft 5 to rotate, the transmission shaft 5 will drive the first bevel gear 201 to rotate synchronously, and then the first bevel gear 201 drives the guide shell 101 to move back and forth along the mixing cylinder 8 in the vertical direction through the second bevel gear 202, the reciprocating screw 203, the moving plate 204 and the horizontal plate 205.

[0051] As a further improvement to the present invention, the method of using this device is as follows: S1: Add the materials to be mixed into the inside of the mixing cylinder 8 through the feed port of the mixing cylinder 8; S2: The geared motor 4 drives the plow blade 6 through the transmission shaft 5 to stir the material inside the mixing drum 8; S3: When the drive shaft 5 rotates, the reciprocating mechanism 2 will also carry the inner cylinder 119 inside the floating material lowering mechanism 1 to lower the floating material to the bottom of the mixing cylinder 8.
