DETAILED DESCRIPTION

[0027] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0029] In the present invention, unless otherwise specified, the directions used, such as "up" and "down", usually refer to the directions shown in the drawings, or to the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directions are not used to limit the present invention.

[0030] For examples, see Figure 1 - Figure 7 , a flame retardant high temperature nylon polymerization modification mixing device, comprising a box body mechanism 1, wherein a stirring and mixing mechanism 2 is arranged inside the box body mechanism 1, and a lifting mechanism 3 is arranged below the stirring and mixing mechanism 2; The box mechanism 1 includes a box 101 and a discharge port 102 arranged on one side of the circumference of the box 101; The stirring and mixing mechanism 2 includes a stirring assembly 4 disposed inside the box 101, and a scraper assembly 5 disposed on the stirring assembly 4. The stirring assembly 4 and the scraper assembly 5 are both rotatably fitted with the inner wall of the box 101, and the bottom of the stirring assembly 4 is in contact with the top of the lifting mechanism 3. When the lifting mechanism 3 is lifted up, the stirring assembly 4 is located above the discharge port 102, and the scraper assembly 5 is deformed into a bent shape; When the lifting mechanism 3 is retracted, the stirring assembly 4 is flush with the lower end of the discharge port 102 , and the scraper assembly 5 is vertically attached to the inner wall of the box body 101 .

[0031] The box body 101 is cylindrical and is used to hold modified particles and other materials to be mixed. The stirring component 4 and the scraper component 5 are rotatably connected. In addition to being able to stir and mix the modified particles and other materials to be mixed, the stirring component 4 also serves as the bottom of the stirring zone and is used to hold the modified particles and other materials to be mixed. Before the modified particles and other materials to be mixed enter the box body 101, the jacking mechanism 3 needs to be in a jacking state, so that the stirring component 4 is lifted above the discharge port 102. The stirring component 4 and the inner wall of the box body 101 higher than the discharge port 102 are combined to form a mixing zone. At this time, the modified particles and other materials to be mixed are added to the mixing zone in proportion, and then the modified particles and other materials in the mixing zone are mixed by rotating the stirring component 4. It should be noted here that when the stirring component 4 is pushed upward by the jacking mechanism 3, the scraper component 5 is deformed into a bent shape. Therefore, rotating the stirring component 4 will drive the bent scraper component 5 to rotate, and the modified particles and other materials in the upper mixing zone can be stirred, thereby improving the mixing efficiency between the modified particles and other materials.

[0032] Furthermore, after the modified particles and other materials are mixed evenly, the lifting mechanism 3 is retracted so that the stirring component 4 will move downward with the lifting mechanism 3 under the action of gravity. When the stirring component 4 is positioned lower than the top edge of the discharge port 102, the modified particles and other materials in the mixing zone will be discharged from the opened discharge port 102, and when the stirring component 4 moves down to be flush with the lower edge of the discharge port 102, the scraper component 5 is in a vertical state. At this time, the scraper component 5 in the vertical state is in contact with the inner wall of the box body 101, so when the stirring component 4 rotates, the modified particles and other materials adsorbed on the inner wall of the box body 101 will be scraped off, and the scraped modified particles and other materials will fall on the stirring component 4 and be discharged from the discharge port 102 under the centrifugal force of the rotation of the stirring component 4.

[0033] A stirring motor 103 is fixedly installed at the bottom of the box body 101, and the output shaft of the stirring motor 103 passes through the bottom of the box body 101 and is connected to a driving rod 104, and the driving rod 104 and the bottom of the stirring component 4 are movably plugged.

[0034] The length of the movable plug-in matching between the driving rod 104 and the stirring component 4 needs to be greater than the distance that the stirring component 4 moves up and down, so that when the stirring component 4 moves up and down with the lifting mechanism 3, the stirring component 4 can always form a transmission connection with the driving rod 104, thereby enabling the stirring motor 103 to maintain a stable power output to the stirring component 4.

[0035] The stirring assembly 4 includes a circular ring plate 401 which is arranged inside the box body 101 and can move up and down, and also includes a stirring blade 402 arranged at the top of the circular ring plate 401, and a centering platform 403 arranged at the center of the circular ring plate 401. A connecting sleeve 404 is arranged at the bottom end of the centering platform 403, and the connecting sleeve 404 and the driving rod 104 are movably matched and plugged; The circular ring plate 401 and the inner wall of the box body 101 are movably matched, and the circular ring plate 401 is tilted downward toward the center, the center platform 403 is set at the center position of the circular ring plate 401 tilted downward, and the stirring blades 402 are distributed in a ring array about the circular ring plate 401.

[0036] There is a movable gap between the circular ring plate 401 and the inner wall of the box body 101, and the movable gap can ensure that the circular ring plate 401 can rotate and move up and down inside the box body 101. Because the size of the movable gap is small, it is only used for matching between the circular ring plate 401 and the inner wall of the box body 101, so the modified particles and other materials to be mixed will not be stuck in the gap.

[0037] Specifically, the circular ring plate 401 is movably placed inside the box body 101, and is pushed up to above the discharge port 102 by the lifting mechanism 3, so that the box body 101 is higher than the inner wall of the discharge port 102 and the circular ring plate 401 and the central platform 403 form a mixing zone, wherein the circular ring plate 401 and the central platform 403 are integrated into a complete receiving plate, which serves as the material receiving bottom of the mixing zone. The driving rod 104 is driven to rotate by the stirring motor 103, so that the driving rod 104 drives the connecting sleeve 404 at the bottom end of the central platform 403 to rotate, thereby rotating the central platform 403 and the circular ring plate 401, and the rotation of the circular ring plate 401 drives the stirring blade 402 to rotate, thereby stirring and mixing the modified particles and other materials.

[0038] The stirring blade 402 is spiral, and the inclination direction of the stirring blade 402 close to the center platform 403 is opposite to the inclination direction of the end away from the center platform 403. When the stirring motor 103 rotates, the inclination direction of the stirring blade 402 close to the center platform 403 will make the modified particles and other materials pass over the blade and enter the next blade area, while the inclination direction of the end away from the center platform 403 will intercept the modified particles and other materials when the stirring motor 103 rotates. When the modified particles and other materials are mixed and discharged, as the circular ring plate 401 moves downward to open the discharge port 102, the mixed modified particles and other materials will be discharged by gravity extrusion. When the mixed modified particles and other materials in the mixing area are almost discharged, the modified particles and other materials remaining in the area of ​​the inclined circular ring plate 401 cannot pass Gravity discharge, at this time, the circular ring plate 401 drives the stirring blade 402 to rotate, and under the action of centrifugal force, the modified particles and other materials in the circular ring plate 401 area are thrown toward the inner wall of the box body 101, and are discharged through the discharge port 102. As the remaining modified particles and other materials become less and less, the particles jump more and more under the stirring of the stirring blade 402, making it difficult to quickly move to the inner wall of the box body 101 and be discharged from the discharge port 102. The spiral design of the stirring blade 402 will make the jumping modified particles and other materials move toward the inner wall of the box body 101 with the centrifugal force. The stirring blade 402 will intercept the modified particles and other materials and cannot jump, so that they can quickly reach the inner wall of the box body 101 through the centrifugal force and then be discharged from the discharge port 102, thereby improving the discharge efficiency.

[0039] A baffle 105 is provided in the box body 101, and the baffle 105 corresponds to the discharge port 102, and a slider 106 is symmetrically provided on the side of the discharge port 102 away from the discharge port 102, and a plug hole is opened on the slider 106; A limit slide bar 107 is provided at the bottom of the box body 101 , and a squeeze spring 108 is sleeved on the limit slide bar 107 . The limit slide bar 107 and the plug-in hole of the slider 106 are plugged and slidably matched, and the squeeze spring 108 abuts against the bottom of the slider 106 .

[0040] There are two limiting slide bars 107 corresponding to the two sliders 106 , and the height of the limiting slide bars 107 is lower than the lower edge of the discharge port 102 , that is, when discharging, the circular ring plate 401 moves down to be flush with the lower edge of the discharge port 102 , and at this time the inclined circular ring plate 401 is not affected by the height of the limiting slide bar 107 .

[0041] Specifically, when the lifting mechanism 3 pushes the circular ring plate 401 to move above the discharge port 102, the extrusion spring 108 pushes the slider 106 to move upward along the limiting slide bar 107, thereby driving the baffle 105 to move upward to block the discharge port 102, and the top of the baffle 105 matches the inclined bottom end of the circular ring plate 401. When the modified particles and other materials are mixed and need to be discharged, the lifting mechanism 3 contracts, and the modified particles and other materials and the circular ring plate 401 are pressed downward under gravity, thereby pushing the baffle 105 to move downward and open the discharge port 102. During the opening of the discharge port 102, the baffle 105 always closes the portion of the discharge port 102 below the circular ring plate 401, so as to prevent the modified particles and other materials from being discharged from the upper end of the discharge port 102 when the discharge port 102 is just opened, and then some particles enter below the circular ring plate 401, that is, enter the interior of the box body 101 from the lower end of the discharge port 102.

[0042] The scraper assembly 5 includes a scraper member 6 rotatably mounted on the outer edge of the circular ring plate 401, and an annular frame 501 disposed at one end of the scraper member 6 away from the circular ring plate 401; The scraper members 6 are arranged in a ring array about the outer edge of the circular ring plate 401 , and the scraper members 6 are in contact with the inner wall of the box body 101 when in a vertical state.

[0043] The diameter of the annular frame 501 is larger than the diameter of the inner wall of the box body 101; A frame groove 109 is formed at the upper end of the inner wall of the box body 101 , and the frame groove 109 matches the annular frame 501 .

[0044] The circular ring plate 401 is provided with a plurality of rotating seats for rotatably connecting the scraper member 6, the scraper member 6 and the annular frame 501 are rotatably connected, and the annular frame 501 is provided with a plurality of rotating ears rotatably connected to the scraper member 6. Specifically, when the jacking mechanism 3 is in a retracted state, the circular ring plate 401 is placed in the box body 101. Under the action of gravity, the circular ring plate 401 contacts the top of the jacking mechanism 3 and is located at a position flush with the lower end edge of the discharge port 102. At the same time, the annular frame 501 is engaged with the bottom end of the frame groove 109 and cannot continue to move downward inside the box body 101, thereby making Under the action of gravity, the circular ring plate 401 pulls the scraper member 6 into a vertical state and fits against the inner wall of the box body 101. As a result, when the stirring motor 103 drives the circular ring plate 401 to rotate to discharge the modified particles and other materials in the mixing area, it will drive the scraper member 6 that fits against the inner wall of the box body 101 to rotate, thereby scraping off the modified particles and other materials adsorbed on the inner wall of the box body 101, and dropping them onto the circular ring plate 401 by gravity, and then being discharged from the discharge port 102 by the centrifugal force of the rotation, thereby improving the discharge efficiency of the modified particles and other materials after mixing.

[0045] The scraper member 6 includes a first connecting rod 601 rotatably mounted on the circular ring plate 401, and also includes a second connecting rod 602 rotatably mounted on an end of the first connecting rod 601 away from the circular ring plate 401; A strip groove 603 is formed at one end of the first connecting rod 601 away from the circular ring plate 401, and a rotation axis of the second connecting rod 602 is movably installed in the strip groove 603; A guide surface 604 is provided on the second connecting rod 602 , and the guide surface 604 is in contact with and matched with one end of the first connecting rod 601 .

[0046] The first connecting rod 601 is provided with a rotating ear at one end close to the circular ring plate 401, and a rotating shaft is provided on the rotating ear. The first connecting rod 601 is rotatably connected to the rotating seat on the circular ring plate 401 through the integrally formed rotating ear and the rotating shaft. The first connecting rod 601 is provided with a connecting seat at one end away from the circular ring plate 401, and a strip groove 603 is provided on the connecting seat. The second connecting rod 602 is provided with a rotating ear and a rotating shaft at one end close to the first connecting rod 601, and the second connecting rod 602 is connected to the first connecting rod 602 through the rotating ear and the rotating shaft. The connecting seat on the first connecting rod 601 is rotatably connected, and the rotating shaft on the second connecting rod 602 can slide in the strip groove 603 of the connecting seat on the first connecting rod 601, and the guide surface 604 on the second connecting rod 602 is set at the bottom end of the rotating ear, so that when the first connecting rod 601 and the second connecting rod 602 slide through the strip groove 603, the connecting seat of the first connecting rod 601 contacts the guide surface 604 on the second connecting rod 602, so that the first connecting rod 601 rotates toward the axial direction of the box body 101.

[0047] Specifically, when the lifting mechanism 3 pushes the circular ring plate 401 to move upward, the first connecting rod 601 is driven to move upward, and the first connecting rod 601 that moves upward is guided by the guide surface 604 to rotate at an angle, so that the rotating shaft on the second connecting rod 602 moves from one end of the strip groove 603 to the other end, and during the continuous upward movement of the lifting mechanism 3, the first connecting rod 601 continues to move upward, but the rotating shaft on the second connecting rod 602 has moved to the other end of the strip groove 603 and cannot move further, so that the second connecting rod 602 begins to rotate toward the axial direction of the box body 101 until the circular ring plate 401 moves above the discharge port 102, and the scraper member 6 is in a bent state at this time. Figure 4 As shown, in this state, the rotation of the stirring assembly 4 will drive the scraper member 6 in the bent state to stir the modified particles and other materials in the mixing zone, thereby improving the working efficiency of stirring and mixing.

[0048] A box cover 110 is rotatably mounted on one side of the box body 101, and a pressing block 111 is disposed on the inner wall of the box cover 110. The pressing block 111 matches the frame groove 109 and abuts against the annular frame 501 when the box cover 110 is closed. A cross bar 502 is disposed at the center of the annular frame 501 .

[0049] When the lifting mechanism 3 is lifting, the box cover 110 needs to be closed so that the pressure block 111 presses against the annular frame 501. In this way, when the lifting mechanism 3 is pushed to lift, the annular frame 501 will be pushed up together. In addition, the annular frame 501 is provided with a cross bar 502, so that when it is disassembled and repaired, it can be directly lifted up, which is convenient for maintenance personnel to operate.

[0050] The lifting mechanism 3 includes an electric telescopic rod 301 disposed inside the box body 101 , a mounting seat 302 disposed at the top of the electric telescopic rod 301 , and a roller 303 rotatably mounted on the mounting seat 302 .

[0051] The electric telescopic rods 301 are arranged in a circular array at the bottom of the box 101 , and the mounting seat 302 is arranged at an angle at the top of the electric telescopic rods 301 , and the inclination makes the roller 303 rotatably mounted on the mounting seat 302 fit the inclined bottom surface of the circular ring plate 401 .

[0052] A control host 7 is fixedly mounted on one side of the outer wall of the box body 101 , and the control host 7 is electrically connected to the stirring motor 103 and the electric telescopic rod 301 .

[0053] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described one by one here. In the above, welding is preferred for all fixed connections. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and deformations can be made to these embodiments without departing from the principle and spirit of the present invention.
