Description

Technical Field

[0001] The utility model relates to the technical field of cylindrical mixers, and particularly to a material distributing and cleaning mechanism for a cylindrical mixer. Background Technique

[0002] A cylindrical mixer is a device widely used in industries such as metallurgy, building materials, chemical engineering, and refractories for mixing and stirring various powdery and granular materials. It consists of structural components such as a cylinder body, a driving device, a supporting roller device, and a feeding and discharging device. When the cylindrical mixer works, materials enter the cylinder body from the feeding port, and the cylinder body slowly rotates under the drive of the driving device. The materials continuously tumble and stir in the cylinder body as the cylinder body rotates, and at the same time, they are subjected to the friction and impact of the lining plate on the inner wall of the cylinder body, so that materials of different components are fully mixed evenly. As the cylinder body continues to rotate, the mixed materials gradually move towards the discharging port and finally are discharged from the discharging port.

[0003] To promote the full mixing of materials, designers usually uniformly fix and install a plurality of material distributing plates on the inner wall of the cylinder. These material distributing plates are carefully designed in terms of shape and angle according to specific requirements. When the cylinder rotates, they can lift and sprinkle the materials, thereby promoting the full mixing of the materials. However, at present, the material distributing plates in the cylindrical mixer have certain limitations. They can neither effectively clean the materials adhered to the inner wall of the cylinder nor prevent the materials from accumulating on the inner wall of the cylinder, which results in the mixing effect being difficult to reach the ideal state and still needs to be further improved.

[0010] Preferably, a sheath is provided below the third bolt, and the sheath is threadedly connected to the sticking plate.

[0011] Compared with the prior art, the beneficial effects of the present utility model are: The material stirring and cleaning mechanism of this cylindrical mixer has the following advantages compared with the traditional technology:

[0012] Through the cooperation among the bottom plate, the cylinder body and the material stirring and cleaning unit, the material to be mixed enters the cylinder body from the feed port. The cylinder body rotates slowly driven by the transmission device, and the material in the cylinder body tumbles and stirs continuously with the rotation of the cylinder body. During this period, the material baffle can lift and sprinkle the material, thereby promoting the material to achieve full mixing. During operation, the operator controls the solenoid valve to be in the open state, and the air supply pipe injects high-pressure air between the two soft sleeves and the inner wall of the annular groove through the insertion pipe. The high-pressure air flows into the top cavity through the top through groove. After the air pressure inside the cavity increases, part of the high-pressure air can act on the upper part of the inner wall of the cylinder body through the air injection holes. In this state, the material adhering to the inner wall of the cylinder body can be effectively cleaned, preventing the material from accumulating on the inner wall of the cylinder body, thereby improving the mixing effect of the cylinder mixer on the material;

[0013] Through the cooperation among the bottom plate, the cylinder body, the material stirring and cleaning unit and the connecting unit, after the soft sleeve shows obvious wear during long-term use, the operator can rotate the second bolt counterclockwise to separate the arc plate from the circular ring, and then rotate the first bolt counterclockwise to replace the baffle and the soft sleeve, so that the soft sleeve fixedly connected to the outside of the baffle is fully pressed against the inner wall of the annular groove, and then the first bolt and the second bolt are reset, and the cylinder mixer can be used normally again;

[0014] Through the cooperation among the bottom plate, the cylinder body, the material stirring and cleaning unit and the protection unit, when the air pressure inside the material baffle is greater than the pulling force of the elastic cord on the abutting ball, a gap is generated between the abutting ball and the air injection hole, and the air injection hole starts to eject air flow. When the air pressure inside the material baffle is less than the pulling force of the elastic cord on the abutting ball, the abutting ball will press against the inner wall of the air injection hole again, and the air injection hole can be closed during non-air injection, which can prevent foreign impurities from blocking the air injection hole, so as to facilitate the subsequent effective cleaning operation of the inner wall of the cylinder body.

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-7 , the present invention provides a technical solution: a material pushing and cleaning mechanism for a cylindrical mixer, comprising: a bottom plate 1, a cylinder body 2 is arranged above the bottom plate 1, circular rings 3 are arranged at both ends of the cylinder body 2, a bracket 4 is fixedly connected to the bottom end of the outer wall of the circular ring 3, the bracket 4 is fixedly connected to the bottom plate 1, a material pushing and cleaning unit is arranged inside the circular ring 3, and the material pushing and cleaning unit comprises: a ring plate 5, the ring plate 5 is rotatably connected to the inner wall of the circular ring 3, the ring plate 5 is fixedly connected to the cylinder body 2, a ring groove 6 is formed on the outer wall of the ring plate 5, a plurality of through grooves 7 are formed on the surface of the ring plate 5 facing the cylinder body 2, a pair of baffle plates 8 are arranged above the ring groove 6, a soft sleeve 9 is fixedly sleeved on the outer wall of the baffle plate 8, the soft sleeve 9 abuts against the inner wall of the ring groove 6, a solenoid valve 10 is arranged above the ring plate 5, an insertion tube 11 is fixedly connected to the air outlet port of the solenoid valve 10, an air supply pipe 12 is fixedly connected to the air inlet port of the solenoid valve 10, a plurality of cavities 13 are formed on one side surface of the cylinder body 2, a plurality of material pushing plates 14 are arranged on the inner wall of the cylinder body 2, and a plurality of air jet holes 26 are formed on both sides of the material pushing plate 14.

[0026] In the specific implementation process, it is particularly worth noting that the cylinder body 2 is the cylindrical structure of the cylindrical mixer. The two ends of the cylinder body 2 are respectively the discharge port and the feed port. The cylinder body 2 can be externally connected to a transmission device. The cylinder body 2 rotates slowly under the drive of the transmission device. The materials in the cylinder body 2 continuously tumble and stir with the rotation of the cylinder body 2, and at the same time are subjected to the friction and impact of the inner wall of the cylinder body 2, so that the materials of different components are fully mixed evenly. As the cylinder body 2 continues to rotate, the mixed materials gradually move towards the discharge port and finally are discharged from the discharge port. The ring plate 5 is rotationally connected to the circular ring 3 through a sealed bearing. The sealed bearing is a type of bearing with a sealing device arranged between the inner and outer rings of the bearing. It isolates the inside of the bearing from the external environment through a special sealing structure, aiming to prevent external pollutants such as dust, impurities, and moisture from entering the inside of the bearing, and at the same time prevent the lubricant inside the bearing from leaking, so as to ensure the stable and reliable operation of the bearing under various complex working conditions. The number of through grooves 7 is the same as that of the cavities 13. The soft sleeve 9 is made of fluororubber material and has a certain flexibility. The solenoid valve 10 is an industrial device controlled by electromagnetic force and belongs to an actuator. It is not limited to hydraulic and pneumatic, but is a basic automation component for controlling fluids. It controls the opening and closing of the valve through electromagnetic force, so as to realize the regulation and control of parameters such as the flow direction, flow rate, and pressure of fluids (such as gases, liquids, etc.). The top end of the air supply pipe 12 is connected to an external high-pressure air supply device. After the solenoid valve 10 is opened, the air supply pipe 12 can inject high-pressure air into the inside of the insertion pipe 11 through the solenoid valve 10. The inside of the cavity 13 is interconnected with the inside of the through groove 7. The inside of the material stirring plate 14 is interconnected with the inside of the cavity 13. The air injection holes 26 are interconnected with the inside of the material stirring plate 14.

[0027] Further, the baffle 8 is connected to the ring plate 5 through a connection unit. The connection unit includes: an arc-shaped plate 15. The arc-shaped plate 15 is located at the top end of the ring plate 5. A sealing strip 16 is fixedly connected to the outer side of the bottom end of the arc-shaped plate 15. The sealing strip 16 abuts against the circular ring 3. A plurality of second bolts 18 are inserted into the upper surface of the arc-shaped plate 15. The second bolts 18 sequentially penetrate through the arc-shaped plate 15 and are threadedly connected to the circular ring 3. The baffle 8 is connected to the arc-shaped plate 15 through a first bolt 17.

[0028] In the specific implementation process, it is particularly worth noting that the sealing strip 16 is made of rubber material and has a certain flexibility. The first bolt 17 sequentially penetrates through the arc-shaped plate 15 and the soft sleeve 9 and is threadedly connected to the baffle 8. After the soft sleeve 9 shows obvious wear during long-term use, the operator can rotate the second bolt 18 counterclockwise to separate the arc-shaped plate 15 from the circular ring 3, and then rotate the first bolt 17 counterclockwise to replace the baffle 8 and the soft sleeve 9.

[0029] Further, a protection unit is provided on the outer side of the inner wall of the air jet hole 26. The protection unit includes: a ball stopper 19 that abuts against the outer side of the inner wall of the air jet hole 26. A support rod 20 is fixedly connected inside the material deflector 14. A plurality of elastic ropes 21 are fixedly connected to both sides of the outer wall of the support rod 20. The end of the elastic rope 21 away from the support rod 20 is fixedly connected to the ball stopper 19.

[0030] In the specific implementation process, it is particularly worth noting that the ball stopper 19 is made of fluororubber material and has a certain flexibility, which is convenient for the ball stopper 19 to fully fit and abut against the outer side of the inner wall of the air jet hole 26. The elastic rope 21 is woven with cotton or chemical fiber as warp and weft yarns and a group of rubber filaments, latex filaments or spandex filaments according to a certain rule, and has the ability of elastic deformation. The elastic rope 21 is in a stretched state.

[0031] Further, the ball stopper 19 fits with the inner wall of the air jet hole 26.

[0032] In the specific implementation process, it is particularly worth noting that the outer side of the inner wall of the air jet hole 26 is an arc structure, which can fully fit and abut against the contact surface of the ball stopper 19, and can effectively prevent foreign impurities from entering the inside of the air jet hole 26.

[0033] Further, a sticker 22 is fixedly sleeved on the outer wall of the material deflector 14. A soft ring 23 is fixedly connected to the upper surface of the sticker 22. The soft ring 23 abuts against the contact surface of the cylinder body 2. A plurality of third bolts 24 are inserted into the lower surface of the soft ring 23. The third bolts 24 sequentially pass through the sticker 22 and the soft ring 23 and are threadedly connected to the cylinder body 2.

[0034] In the specific implementation process, it is particularly worth noting that the soft ring 23 is made of rubber material and has a certain flexibility. After the third bolt 24 is rotated counterclockwise to be separated from the cylinder body 2, the material deflector 14 can be disassembled. After the material deflector 14 is damaged and deformed after long-term use, it can be replaced.

[0035] Further, a sheath 25 is provided below the third bolt 24. The sheath 25 is threadedly connected to the sticker 22.

[0036] In the specific implementation process, it is particularly worth noting that the sheath 25 is made of hard plastic material. The sheath 25 can protect the threaded connection part of the third bolt 24, so as to facilitate the subsequent smooth disassembly operation of the third bolt 24.

[0037] Working principle:

[0038] Material deflecting and cleaning operation for the materials inside the cylinder body:

[0039] First, the material to be mixed enters the cylinder body 2 from the feed port. The cylinder body 2 rotates slowly under the drive of the transmission device. The material in the cylinder body 2 tumbles and stirs continuously as the cylinder body 2 rotates. During this period, the material baffle 14 can lift and sprinkle the material, thereby promoting the material to achieve full mixing. During operation, the operator controls the solenoid valve 10 to be in the open state. The air supply pipe 12 injects high-pressure air between the two soft sleeves 9 and the inner wall of the annular groove 6 through the insertion pipe 11. The high-pressure air flows into the internal cavity 13 of the top end through the through groove 7 at the top end. After the air pressure inside the cavity 13 increases, part of the high-pressure air can act on the upper part of the inner wall of the cylinder body 2 through the air injection holes 26. In this state, the material adhered to the inner wall of the cylinder body 2 can be effectively cleaned, preventing the material from accumulating on the inner wall of the cylinder body 2, thereby improving the mixing effect of the cylindrical mixer on the material. As the cylinder body 2 continues to rotate, the mixed material gradually moves towards the discharge port and finally discharges from the discharge port;

[0040] Replacement operation of the soft sleeve:

[0041] After the soft sleeve 9 shows obvious wear during long-term use, the operator can rotate the second bolt 18 counterclockwise to separate the arc-shaped plate 15 from the circular ring 3. Then rotate the first bolt 17 counterclockwise to replace the baffle 8 and the soft sleeve 9, so that the soft sleeve 9 fixedly connected to the outside of the baffle 8 is fully pressed against the inner wall of the annular groove 6. Then reset the first bolt 17 and the second bolt 18, and the cylindrical mixer can be used normally again;

[0042] Anti-blocking operation of the air injection holes:

[0043] After the air pressure inside the material baffle 14 is greater than the pulling force of the elastic cord 21 on the abutting ball 19, a gap is generated between the abutting ball 19 and the air injection hole 26, and the air injection hole 26 starts to eject air. After the air pressure inside the material baffle 14 is less than the pulling force of the elastic cord 21 on the abutting ball 19, the abutting ball 19 will re-abut against the inner wall of the air injection hole 26, which can realize that the air injection hole 26 is in a closed state during non-air injection, and can prevent foreign impurities from blocking the air injection hole 26, so as to facilitate the subsequent effective cleaning operation of the inner wall of the cylinder body 2.

[0044] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
