DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside”, etc., are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. This embodiment is written in a progressive manner.

[0031] like Figures 1 to 7 As shown, a corn starch slurry mixing machine of the present invention comprises a storage barrel 1 for containing materials, two filter plates 2 and two piston plates 3 located in the storage barrel 1, the two filter plates 2 are close to each other and located in the middle of the storage barrel 1, the two piston plates 3 are located on both sides of the two filter plates 2 along the axis direction of the storage barrel 1, and the filter plates 2 are fixed in the storage barrel 1, and the piston plates 3 reciprocate in the storage barrel 1;

[0032] Two groups of material guide structures 4 for material circulation are arranged on the outer wall of the material storage barrel 1 , one group of material guide structures 4 is used for conveying starch, and the other group of material guide structures 4 is used for conveying water. The material guide structures 4 are connected to the space between the two filter plates 2 .

[0033] In detail, the two filter plates 2 can divide the internal space of the storage barrel 1 into two extrusion spaces on both sides and a flushing space in the middle. The two piston plates 3 are respectively located in the two extrusion spaces. When the two piston plates 3 synchronously reciprocate along the axial direction of the storage barrel 1, one extrusion space increases, while the other extrusion space decreases, and the material flows through the two filter plates 2. When in use, corn starch and water can be introduced between the two filter plates 2 through two sets of material guide structures 4 respectively. Water can pass through the filter plates 2 and flow into the extrusion space. Part of the dispersed starch slurry can pass through the filter plates 2 and enter the extrusion space. When a specified amount of starch and water is stored in the storage barrel 1, the two piston plates 3 are synchronously pushed to The piston plate 3 reciprocates along the axial direction of the storage barrel 1, so that the piston plate 3 in one extrusion space squeezes water through the two filter plates 2. The water can flush the starch between the two filter plates 2, so that the starch is impacted and dispersed and mixed into the water. At the same time, the filter plate 2 can be used to intercept the starch agglomerated in the water. Combined with the continuous flow of water, the starch blocks are dispersed and broken, ensuring that the starch can be quickly and comprehensively mixed into the water. Since the material repeatedly flows between the two extrusion spaces and is repeatedly filtered by the filter plate 2, the starch and water are comprehensively mixed, thereby improving the mixing uniformity and preventing the material from being deposited in a dead corner and affecting the slurry concentration.

[0034] In actual use, auxiliary additives may be added to the corn starch, and the electric heating structure may be used to heat the storage barrel 1 to meet different production requirements of starch slurry.

[0035] The internal space of the storage barrel 1 is divided into extrusion spaces on both sides and a flushing space in the middle by two filter plates 2, so that the material flows repeatedly between the two extrusion spaces, and the flow of the material is used to flush and dissolve the starch particles. The filter plate 2 can be used to disperse the material and intercept the block material, so that the block material is continuously flushed and dissolved by the fluid, which greatly improves the material dissolution speed, enhances the material dispersion effect, improves the uniformity of the slurry concentration, and improves the work efficiency; the two piston plates 3 are used to reciprocate along the axial direction of the storage barrel 1, so that the material is subjected to continuous pressure changes in the extrusion space, which is conducive to further dispersion and mixing of the material and avoids the material from clogging the filter plate 2; in summary, the corn starch slurry mixer achieves effective dispersion and mixing of starch through a unique design, improves the quality of the slurry, and also simplifies the operation process and improves production efficiency.

[0036] Furthermore, columns 5 are provided at both ends of the storage barrel 1, an outer ring 6 is sleeved on the outer side of the storage barrel 1, the axis of the outer ring 6 is perpendicular to the axis of the storage barrel 1, the columns 5 are installed on the inner wall of the outer ring 6, and the axis of the outer ring 6 is horizontal;

[0037] Side rings 7 are provided on both end surfaces of the outer ring 6 , and the outer ring 6 rotates on the side rings 7 . The two side rings 7 are fixedly connected by two side plates 8 , and each side plate 8 is provided with a support leg 9 .

[0038] In detail, the side ring 7, the side plate 8 and the support leg 9 can provide support for the outer ring 6 and the storage barrel 1 inside it. The outer ring 6 can drive the storage barrel 1 to rotate in the vertical direction through the column 5, that is, the storage barrel 1 rotates around the axis of the outer ring 6, so that the two extrusion spaces in the storage barrel 1 continuously exchange positions in the vertical direction, thereby utilizing the rotation of the storage barrel 1 to improve the mixing effect of the materials, and since the two extrusion spaces are exchanged in the vertical direction, gravity can be used to realize the flow of materials between the two extrusion spaces.

[0039] Furthermore, the material guiding structure 4 includes a square tube 10, one end of the square tube 10 passes through the outer ring 6, the other end of the square tube 10 is installed on the outer wall of the storage barrel 1, and the square tube 10 is connected with the storage barrel 1, a moving column 11 is slidably arranged in the square tube 10, and the sliding direction of the moving column 11 is along the width direction of the square tube 10, a spring piece 12 is arranged between the moving column 11 and the square tube 10, one end of the moving column 11 is arranged with a slope 13, and the other end of the moving column 11 is arranged with a sealing plate 14, and the sealing plate 14 blocks the connecting position between the square tube 10 and the storage barrel 1.

[0040] In detail, a spring sheet 12 is provided on one side wall of the movable column 11, and a material guiding channel is formed between the other side wall thereof and the inner wall of the square tube 10. In the natural state, the elastic thrust of the spring sheet 12 on the movable column 11 makes the side wall of the movable column 11 fit with the inner wall of the square tube 10, that is, the material guiding channel is in a closed state. When material guiding is needed, the movable column 11 can be pushed to slide in the square tube 10 through the inclined surface 13. At this time, the material guiding channel is opened, the sealing plate 14 is offset horizontally, the square tube 10 and the material storage barrel 1 are in a connected state, and the material can enter the material storage barrel 1 through the material guiding channel. When the material introduction is completed, the spring sheet 12 pushes the movable column 11 to return to its initial position, the material guiding channel is closed, and the sealing plate 14 blocks the square tube 10.

[0041] By adopting the above-mentioned structural manner, no material will remain in the material guiding channel when the device is idle.

[0042] When the two groups of material guiding structures 4 are feeding, one group of material guiding structures 4 is used to convey starch, and the other group of material guiding structures 4 is used to convey water. At this time, the storage barrel 1 is horizontal, and the material guiding structures 4 are vertically upward. The materials are conveyed into the storage barrel 1 from above through the material guiding structures 4. When the material guiding structures 4 are vertically downward, the material guiding structures 4 are located below the storage barrel 1. At this time, one group of material guiding structures 4 is opened, and the mixed materials in the storage barrel 1 can be discharged through the material guiding structures 4, thereby realizing the feeding and discharging work.

[0043] It should be pointed out that since the cross-section of the storage barrel 1 is circular, in order for the sealing plate 14 to be able to fit the shape of the curved inner wall of the storage barrel 1 and move normally and seal the square tube 10, the square tube 10 needs to deviate from the axis of the storage barrel 1. In this way, when the material guiding structure 4 is opened, the sealing plate 14 will be separated from the inner wall of the storage barrel 1 instead of sliding on the inner wall of the storage barrel 1, thereby enabling the structure to be used normally.

[0044] Furthermore, a plurality of rotating shafts 15 are rotatably disposed between the two filter plates 2 , and a plurality of fan blades 16 are disposed on the outer wall of each rotating shaft 15 .

[0045] In detail, when the material passes through the two filter plates 2, the material will push the rotating shaft 15 and the fan blades 16 to rotate, thereby using the fan blades 16 to stir the material to improve its mixing uniformity.

[0046] Furthermore, each of the piston plates 3 is provided with a pushing structure, and the pushing structure is used to provide power for the movement of the piston plate 3;

[0047] The pushing structure includes a turntable 17 rotatably mounted on the end surface of the storage barrel 1, the turntable 17 is located on the inner side of the storage barrel 1, and a plurality of connecting rods 18 are rotatably arranged on the outer wall of the turntable 17. The piston plate 3 is connected to the end surface of the storage barrel 1 through a plurality of adjusting rods 19. The adjusting rods 19 are inclined, and the plurality of adjusting rods 19 are distributed in a ring shape around the axis of the storage barrel 1, and connecting balls are arranged at both ends of the adjusting rods 19. The adjusting rod 19 is rotatably connected to the storage barrel 1 and the piston plate 3 respectively through two connecting balls. A connecting sleeve 20 is provided on the sliding sleeve of the adjusting rod 19, and the connecting rod 18 is rotatably connected to the connecting sleeve 20.

[0048] In detail, the rotation axis of the connecting rod 18 on the turntable 17 is perpendicular to the axis of the storage barrel 1, and the connecting rod 18 is rotatably connected to the connecting sleeve 20 through a connecting ball. When the turntable 17 rotates, the turntable 17 will gradually rotate to a vertical state by driving multiple inclined adjustment rods 19 through multiple connecting rods 18 and multiple connecting sleeves 20. At this time, multiple adjustment rods 19 will synchronously push the piston plate 3 to move toward the filter plate 2. When the turntable 17 continues to rotate, the adjustment rod 19 tilts from the vertical state to the other side, and the piston plate 3 moves in a direction away from the filter plate 2, thereby realizing the movement of the piston plate 3 in the extrusion space.

[0049] It should be pointed out that the above-mentioned structural method occupies a small space, has a simple structure and is easy to operate. As the piston plate 3 moves, the space between the piston plate 3 and the end of the storage barrel 1 changes. In order to avoid the internal air pressure affecting the movement of the piston plate 3, an air vent can be opened at the end of the storage barrel 1 to connect the space with the outside world.

[0050] Furthermore, the column 5 is transmission-connected with the turntable 17, the column 5 is rotationally connected with the outer ring 6, a thread is provided on the outer wall of the column 5, and a threaded sleeve 21 is screwed on the column 5, and two sliding columns 22 are relatively fixed on the outer wall of the threaded sleeve 21;

[0051] An annular groove 23 is formed on the end surface of each side ring 7 . The annular groove 23 is composed of a plurality of wavy grooves. The axis of the annular groove 23 coincides with the axis of the side ring 7 . The sliding column 22 is slidably installed in the annular groove 23 .

[0052] In detail, when the outer ring 6 rotates, it can drive the sliding column 22 to slide in the annular groove 23 through the column 5 and the threaded sleeve 21. Due to the limitation of the shape of the annular groove 23, the distance between the sliding column 22 and the axis of the outer ring 6 changes repeatedly. At this time, the sliding column 22 will drive the threaded sleeve 21 to move repeatedly on the column 5. Since the column 5 is threadedly connected to the threaded sleeve 21, the column 5 can rotate forward and backward repeatedly, thereby driving the turntable 17 to rotate forward and backward repeatedly. The turntable 17 drives the piston plate 3 thereon to reciprocate, thereby providing power for the movement of the piston plate 3.

[0053] Furthermore, the end of the storage barrel 1 is connected to the inner wall of the outer ring 6 via a connecting column 24 , a sliding block 25 is slidably provided on the connecting column 24 , and the sliding block 25 is fixedly connected to the threaded sleeve 21 .

[0054] In detail, by setting the connecting column 24, the storage barrel 1 and the outer ring 6 can be conveniently connected and fixed to prevent the storage barrel 1 from rotating at will when the column 5 rotates. The slider 25 can support and guide the threaded sleeve 21, thereby ensuring that the sliding column 22 moves smoothly on the side ring 7 while being perpendicular to the side ring 7.

[0055] Furthermore, a transmission ring 26 is provided on the outer wall of the outer ring 6 , a transmission wheel 27 is provided on the transmission ring 26 , and a motor 28 for providing power to the transmission wheel 27 is provided on the outer ring 6 .

[0056] In detail, the motor 28 can drive the outer ring 6 to rotate through the transmission wheel 27 and the transmission ring 26, thereby driving the storage barrel 1 to operate.

[0057] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
