Description

Technical Field

[0001] The utility model relates to the technical field of stirring equipment, in particular to a ploughshare mixer. Background Art

[0002] At present, most of the equipment used for material stirring and mixing on the market adopts vertical or horizontal fixed containers for material stirring and mixing. The two ends of the container are fixed or one end is fixed, and the other end is connected by a flange. The stirring parts are designed as an integral structure, and the entire equipment cannot be quickly disassembled for cleaning. When it is necessary to clean the inside of the equipment, it is necessary to manually enter the equipment through the inspection port to wipe and rinse, which is time-consuming and labor-intensive, and also poses a safety hazard.

[0003] On the other hand, most of the stirring parts inside the equipment are fixed with screws to form a split connection structure. As the characteristics of the stirring materials are complex, some viscous materials or materials that need to be sprayed with liquid make it easy for the materials to stick to the wall during the mixing and discharging process. Residual substances are easy to stick between the stirring parts of the split structure and are not easy to remove. At the same time, due to the fixed structure at both ends of the horizontal equipment, it is impossible to thoroughly clean the corners of the equipment and the cleanliness of the inner surface of the equipment cannot be guaranteed. Although the vertical equipment has fewer sanitary dead corners and low residue, the overall appearance of the vertical equipment is high, the plant space requirements are high, and it is not convenient for cleaning operations.

[0097] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0098] This embodiment provides a plowshare mixer, which is used for material mixing and can achieve the function of rapid cleaning.

[0099] like Figure 1 As shown, the plowshare mixer includes a barrel 2, end covers 3 arranged at both ends of the barrel 2 and a stirring device 4 arranged in the barrel 2, the stirring device 4 includes a main shaft 41, a plurality of plowshares 42 and a plow handle 43 connected to the main shaft 41 and the plowshare 42, the end cover 3 includes a movable end cover 31 which is detachably connected to one end of the barrel 2 and can move axially, one end of the main shaft 41 is connected to the movable end cover 31, and the main shaft 41, the plow handle 43 and the plowshare 42 are welded to each other; at least one first cleaning device 6 is provided on the outer surface of the barrel 2, and part of the first cleaning device 6 extends into the inner cavity of the barrel 2, and the first cleaning device 6 is used to connect to an external cleaning liquid source and spray the cleaning liquid into the inner cavity of the barrel 2.

[0100] Specifically, in this embodiment, the plowshare mixer adopts a horizontal O-shaped structure design of the cylinder 2 as a whole, and the vertical plates at both ends are thickened. After the equipment wallboard and the cylinder 2 are assembled for the first time, the stopper mounting holes on the wallboards at both ends are processed by hanging boring. The integrated hanging boring process can ensure the concentricity of the mounting shaft holes at both ends of the equipment. After the main shaft 41 of the equipment is installed, the runout of the shaft is ≤0.1mm, and the overall operation of the equipment is more stable. The cylinder 2 is a cylindrical metal cylinder, and the main shaft 41, plowshare 42 and plow handle 43 of the stirring device 4 are also metal parts. The plowshare 42 is composed of two symmetrical plowshares, and there is a scraper 44 at each end of the left and right ends of the main shaft 41 (that is, half of the plowshare 42 is a plowshare), and the scraper 44 is close to the surface of the end cover 3 on the left and right sides. The main shaft 41, the plow handle 43 and the plowshare 42 are welded to each other, and there are no screws inside the entire equipment. All components adopt a fully welded structure to avoid material residues and bacterial growth caused by the previous installation with screws. The plowshare structure can extrude and fully blend, sprinkle and diffuse the materials during the mixing process. The movement trajectories of the powder and granular materials in the mixing device are crisscrossed and collide with each other, generating strong vortices to achieve the desired mixing effect. One end of the cylinder 2 is a removable and axially movable movable end cover 31, and the other end of the cylinder 2 is a removable but relatively fixed fixed end cover 32. The movable end cover 31 can drive the main shaft 41 to move, and the entire stirring device 4 is moved out of the cylinder 2 for cleaning. The first cleaning device 6 is specifically a pipe fitting for spraying cleaning liquid, and the nozzle part is inserted into the cylinder 2 to spray cleaning liquid. The plowshare 42 mixer is also provided with a water receiving trough (not shown in the figure), and the sewage cleaned by the first cleaning device 6 in the cylinder 2 and the sewage cleaned by the stirring device 4 as a whole moved out of the cylinder 2 are discharged through the water receiving trough. In other embodiments, both ends of the cylinder 2 can also be movable end covers 31.

[0101] The plowshare mixer is connected to the movable end cover 31 through one end of the main shaft 41, and the movable end cover 31 is detachably connected to one end of the cylinder 2 and can move axially, so that the movable end cover 31 can drive the main shaft 41 to move, and the entire stirring device 4 is moved out of the cylinder 2 for quick cleaning. There is a larger operating space for quick flushing, which improves the cleaning efficiency and is also convenient for removing residual materials between the various components of the cleaning stirring device 4, thereby improving the cleaning effect. The main shaft 41, the plow handle 43 and the plowshare 42 are welded to each other, and it is not easy to leave residual materials at the connection, so that cleaning is cleaner. Through the above-mentioned first cleaning device 6, before the stirring device 4 is moved out of the cylinder 2 as a whole, the first cleaning device 6 can spray cleaning liquid into the cylinder 2 to flush the stirring device 4, thereby avoiding the cleaning liquid splashing out of the outside of the plowshare mixer and increasing the cleaning workload. By using the first cleaning device 6 to spray inside the cylinder 2 and cleaning the stirring device 4 that is removed as a whole outside the cylinder 2, the combination of these two cleaning methods realizes the combination of spraying inside the cylinder and rapid cleaning by removing the entire device outside the cylinder, thereby improving the cleaning efficiency, and can also clean and remove residual materials between the components of the stirring device 4, thereby improving the cleaning effect.

[0102] Among them, Figure 1 As shown, the first cleaning device 6 includes two cleaning pipes 61, and the two cleaning pipes 61 extend into the inner cavity of the barrel 2 from different positions of the barrel 2; and / or, a rotating nozzle (not shown in the figure) is installed at the end of the first cleaning device 6 extending into the barrel 2, and the rotating nozzle includes a plurality of nozzles with different spraying directions. The first cleaning device 6 extends into the barrel 2 from different positions of the barrel 2 through a plurality of cleaning pipes 61, thereby increasing the cleaning range. The above-mentioned rotating nozzle is installed at the end of the first cleaning device 6 extending into the barrel 2, thereby increasing the cleaning range, thereby improving the cleaning efficiency and cleaning effect.

[0103] In other embodiments, the first cleaning device 6 may have different structural forms, and the number of the entire first cleaning device 6 or the number of cleaning pipes 61 may be adjusted accordingly as needed; when there are multiple cleaning pipes 61, there may be no rotating nozzle; conversely, if a rotating nozzle is already provided, there may be only one cleaning pipe 61.

[0104] In other embodiments, the first cleaning device 6 and the outer wall of the cylinder 2 can also be rotatably connected. For example, the cleaning pipe 61 of the first cleaning device 6 is connected to the cylinder 2 by a rotating connection similar to a universal wheel, so that the first cleaning device 6 can spray cleaning liquid into the cylinder 2 at different inclination angles, thereby expanding the cleaning range and improving the cleaning effect.

[0105] One end of the main shaft 41 is connected to the movable end cover 31 through a live bolt 33. The live bolt 33 ensures that the movable end cover 31 will not be pulled out during the operation of the plowshare mixer; and when cleaning is required, the live bolt 33 can be easily removed to separate the movable end cover 31 from the cylinder 2.

[0106] Among them, Figure 1 As shown, the plowshare mixer also includes a base 7, the barrel 2 is arranged on the base 7, and the base 7 is also provided with a slider 71 and a slide rail 72 that slide with each other, the movable end cover 31 is connected to the slider 71, and the slide rail 72 is parallel to the main shaft 41. Through the sliding cooperation between the slider 71 and the slide rail 72, the movable end cover 31 can be moved smoothly, and the stirring device 4 can be moved out of the barrel 2 as a whole.

[0107] The base 7 adopts an arched bracket design, the arched bracket is spliced ​​with plates, and the equipment body is connected and installed with the base 7 to ensure that the overall operation is stable and the shape is beautiful during high-power operation.

[0108] like Figure 2 and Fig.13 As shown, the plowshare mixer also includes a main shaft 41 braking and positioning device, whose main components include a photoelectric sensor 11, an air-compressed butterfly brake 12, a claw plate 13, a main shaft 41, a bearing seat 5 and other components. The claw plate 13 is installed at the tail end shaft of the movable end cover 31. The claw plate 13 is provided with a long and a short sensing edge strip distributed at 90°, and is equipped with a corresponding photoelectric sensor 11. When the main shaft 41 needs to be shut down, the speed of the main shaft 41 is slowly reduced to a certain range through the control of the frequency converter, and then the air-compressed butterfly brake 12 is used to completely stop the main shaft 41 to achieve shutdown, while ensuring that the pulling and cleaning of the main shaft 41 will not interfere with the flying knife 142 component of the crushing device 14.

[0109] The end cover 3 further includes a fixed end cover 32 which is detachably connected to the other end of the cylinder 2 and fixed in position. The fixed end cover 32 is connected to the driving mechanism 1. The output shaft of the driving mechanism 1 passes through the fixed end cover 32 and is pluggably connected to the other end of the main shaft 41. The other end of the main shaft 41 is pluggably connected to the output shaft of the driving mechanism 1, so that the disassembly between the main shaft 41 and the driving mechanism 1 is simple, and the other end of the main shaft 41 (i.e., the end connected to the driving mechanism 1) is convenient for cleaning.

[0110] Among them, Figure 5-7 As shown, a square socket 411 is provided at one end of the main shaft 41 close to the fixed end cover 32, and a square plug 151 is provided at the end of the output shaft, and the plug 151 is pluggable connected to the socket 411. Through the pluggable connection between the plug 151 and the socket 411, the main shaft 41 is pluggable connected to the drive mechanism 1. With the square matching connection structure, the drive mechanism 1 realizes the motion transmission of the main shaft 41.

[0111] Among them, Fig.11 and Fig.12 As shown, the bottom of the cylinder 2 is provided with a discharging device 8 that can be detachably connected. The discharging device 8 includes a discharging box 81, a mounting seat 101, a discharging valve plate 86 and other components. The mounting seat 101 fixes the discharging box 81 on the cylinder 2, and the discharging valve plate 86 controls the opening or closing of the discharging. The discharging box 81 is provided with a connecting hole 82, and the connecting hole 82 can be selectively connected to the second cleaning device 83 or the plug 84. The second cleaning device 83 is used to extend from the connecting hole 82 into the inner cavity of the discharging box 81 during cleaning. The second cleaning device 83 is provided with a rotatable cleaning ball at the end where it extends into the connecting hole; the plug 84 is used to block the connecting hole 82 during discharging. The discharging device 8 is detachably connected to the bottom of the cylinder 2 to form a separate connection structure, which is convenient for the later maintenance and maintenance of the plowshare mixer. The second cleaning device 83 extends into the inner cavity of the discharging box 81, and a rotatable cleaning ball is provided at its end, so that the components in the discharging box 81 can be cleaned.

[0112] The whole equipment of the plowshare mixer is designed with a rotating cleaning ball, a water receiving trough, etc. for cleaning the barrel 2, the stirring device 4 and the discharging device 8. The equipment can be automatically cleaned online, and the sewage flows into the designated sewage outlet through the water receiving trough to avoid polluting the workshop.

[0113] like Figure 1 , 3 As shown in Figures 4 and 5, an inspection port 9 is also provided on the cylinder 2, and the inspection port 9 is detachably connected to the cylinder 2. Specifically, in this embodiment, the discharge port and the inspection port 9 of the cylinder 2 corresponding to the discharge device 8 are both cut by the wire cutting process, and the discharge door plate and the inspection door plate are consistent with the inner wall of the cylinder 2. There is no dead angle in the mixing process of the material, which improves the mixing uniformity of the equipment and reduces the residual material in the equipment to less than 2‰. The inspection door plate is engraved with a dovetail groove and equipped with an O-ring 92. After the clamp 91 is pressed, it ensures that the inner wall of the cylinder 2 is on the same arc surface, and there is no dead angle in the mixing process of the equipment, and there is no residue when discharging. A safety switch 97, a torsion spring 99 and a sliding bearing 100 are provided at the hinge switch to ensure that the opening and closing of the inspection door plate are flexible and easy. At the same time, a safety switch 97 is provided on the outside of the door plate. When the inspection door component is opened, the equipment stops running to ensure the safety of life during maintenance and cleaning.

[0114] like Figure 1 and Figure 8As shown, both ends of the main shaft 41 are provided with gas sealing devices 10 on the outside of the end cover 3, and the gas sealing device 10 comprises a mounting seat 101, a pressure cover 102, two sealing seats 103 and a sealing ring 104. The sealing ring 104 is made of special latex with good elasticity and wear resistance; the pressure cover 102 is provided with a gas nozzle interface, and the air pressure generated in the seal causes the sealing ring 104 to be compressed and tightly hold the main shaft 41, so as to prevent the leakage of powder and granular bodies. The fasteners pass through the pressure cover 102 and the mounting seat 101 in turn and are connected to the end cover 3. The two sealing seats 103 are arranged in a sealing cavity 105 formed by the mounting seat 101 and the pressure cover 102, and the sealing cavity 105 is connected to the external compressed air. The sealing ring 104 is arranged between the two sealing seats 103 and is sleeved on the main shaft 41. The sealing ring 104 and the sealing seat 103 are clearance-matched to form a sealing channel 106 connected to the sealing cavity 105 and the inner cavity of the cylinder 2.

[0115] The inspection port 9 can also be used to clean the components in the cylinder 2, and can also be used to observe the operation of the equipment and inspect the equipment. Through the above-mentioned gas sealing device 10, compressed air is input through the sealing chamber 105 and the sealing channel 106 to prevent the leakage of powder and granular materials in the cylinder 2, thereby playing a sealing role. At the same time, the gas sealing structure is arranged on the outside of the end cover 3, and its various parts are split in half, that is, the space between the mounting seat 101 and the pressure cover 102, between the two sealing seats 103, and between the sealing seat 103 and the sealing ring 104 are all split structures, such as Fig. 9 As shown, from the end face of the gas sealing structure, the parts of the gas sealing structure are annular structures, which are split in half relative to the main shaft 41. The gas sealing structure can be disassembled and the fasteners can be removed, and the gland 102 can be separated from the mounting seat 101, and the two sealing seats 103 and the sealing ring 104 can also be separated without disassembling the sealing structure as a whole. Therefore, the installation and disassembly are very simple, and it is easy to clean, avoiding the generation of microorganisms and contamination of materials by residual materials.

[0116] Among them, Figure 1 As shown, the plowshare mixer also includes a bearing seat 5 arranged outside the two end covers 3. The two ends of the main shaft 41 pass through the end covers 3 and are connected to the bearing seat 5. The two bearing seats 5 are respectively connected to the corresponding end covers 3; the bearing seat 5 is an integral casting. The conventional reinforcing rib plate and seat bearing design at both ends of the wall panel of the equipment are eliminated. The bearing seat 5 supporting the two ends of the main shaft 41 adopts an integral casting, and its surface is more concise and beautiful. The simple appearance of the structure is more convenient to clean, reducing the previous situation of dust falling on the rib plate and being difficult to clean, and avoiding places where the gap cannot be cleaned. At the same time, the cast bearing seat 5 adopts a closed structure design, which also meets the current high requirements of the pharmaceutical and food industries for mixing equipment.

[0117] like Figure 2 and Fig.10As shown, two crushing devices 14 are also provided on the cylinder 2, and the crushing device 14 is installed at the oblique lower position of the cylinder 2. The crushing device 14 includes a flying knife motor 141 arranged on the outside of the container, a plurality of flying knives 142 arranged inside the container, and a flying knife shaft 143 connecting the flying knives 142 and the flying knife motor 141; the flying knife shaft 143 and the axis of the flying knife motor 141 are the same axis, which can ensure the concentricity during high-speed rotation. The flying knives 142 are designed in several groups, and every two pieces are distributed in a cross. When the material passes through the range of the flying knife blades, it will be instantly crushed and scattered by its high-speed rotation, so that the uniformity of material mixing is optimized.

[0118] When in use, the ploughshare mixer drives the main shaft 41 of the equipment to rotate through the driving device, and the main shaft 41 makes a circular motion in the specified direction. The multiple sets of flying knives 142 on the cylinder 2 are embedded in the material and rotate at high speed; the material in the cylinder 2 is thrown up by the strong action of the ploughshare 42, and a part of the material makes a circular motion along the cylinder wall, while the other part of the material is thrown toward the center of the cylinder 2 or scattered toward the two ends of the cylinder 2 along the normal direction of the ploughshare 42; at the same time, when the material flows through the high-speed rotating flying knives 142, it is sheared and strongly diffused at high speed, and the materials collide with each other in the powder and particle mixing equipment, generating strong eddy currents, and achieving uniform mixing in a very short time.

[0119] Although the specific implementations of the utility model are described above, those skilled in the art should understand that this is only an example, and the protection scope of the utility model is defined by the attached claims. Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
