Description

Technical Field

[0001] This utility model relates to the field of fire-retardant coating preparation technology, specifically, to a double-helix mixing tank for fire-retardant coating preparation. Background Technology

[0002] Fire-retardant coatings are special coatings that can reduce the flammability of the coated material surface, inhibit the rapid spread of fire, and improve the fire resistance limit of the coated material. Therefore, they are widely used in many fields. In the preparation process of fire-retardant coatings, the corresponding raw materials need to be mixed and stirred, which requires the use of corresponding mixing tanks to achieve the mixing process.

[0003] Chinese patent CN208512531U discloses a double-helix high-efficiency stirring vessel, which includes a shell. A first material inlet is located at one end of the top of the shell, a second material inlet is located on one side of the shell surface, and a material outlet is located at the center of the bottom of the shell. A stabilizing foot is provided at the bottom of the shell. A thermometer is located on the top of the shell away from the first material inlet, with one end of the thermometer extending into the interior of the shell. A motor is located at the center of the top of the shell. A connecting shaft is located inside the shell. The output shaft of the motor passes through the shell and extends into the interior of the shell, where it is fixedly connected to the top of the connecting shaft. The bottom of the connecting shaft... The unit is fixedly installed with a plate, and two sets of spiral stirring rods are set at the bottom of the plate. This double-spiral high-efficiency mixing vessel has high mixing efficiency, saves time, improves work efficiency, ensures the quality of fire-retardant coatings during mixing, and has a reasonable design and strong practicality.

[0028] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0029] Example 1

[0030] A preferred embodiment of the double-spiral mixing tank for preparing fire-retardant coatings provided by this utility model is as follows: Figures 1 to 6 As shown: A double-spiral mixing tank for preparing fireproof coating includes a tank body 5, a discharge pipe 7 fixedly connected to the middle position of the bottom end of the tank body 5, a vibration discharge component 8 provided on one side of the bottom end of the tank body 5, a fixing component 2 provided at equal angles on the top end of the tank body 5, a top cover 9 movably connected to the top end of the tank body 5, a feed hopper 10 fixedly connected to the middle position of the top end of the top cover 9, servo motors 1 fixedly connected to both sides of the top end of the top cover 9, the output end of the servo motor 1 passes through the top cover 9 and is fixedly connected to an installation component 3 through a coupling, and a spiral stirring rod 4 movably connected to the bottom end of the installation component 3.

[0031] The fixing component 2 includes a limiting groove 206, which is opened at an equal angle on the inner wall of the top of the tank body 5. A rotating plate 203 is rotatably connected to the top of the tank body 5 at an equal angle. A lever 204 is fixedly connected to one side of the top of the rotating plate 203. A limiting block 202 is fixedly connected to the surface of the top cover 9 at an equal angle. A fixing groove 201 is opened at an equal angle on the surface of the top cover 9. A rubber pad 205 is fixedly connected to one side of the top wall and the bottom wall of the fixing groove 201. By using the engagement of the limiting block 202 with the inside of the limiting groove 206, and by using the rotation of the rotating plate 203 to engage with the inside of the fixing groove 201, the top cover 9 and the tank body 5 can be quickly disassembled and assembled. Then, the staff can open the top cover 9 to facilitate the cleaning of the inner wall of the tank body 5 and avoid residual materials from affecting the preparation of other fireproof coatings.

[0032] In this embodiment, the limiting block 202 and the limiting groove 206 form an engaging structure. The limiting block 202 and the limiting groove 206 are convex in top view. By using the engaging of the convex limiting block 202 and the limiting groove 206, the pre-engagement and installation of the top cover 9 and the top of the tank body 5 can be achieved.

[0033] In this embodiment, the cross-sectional shape of the lever 204 is an inverted L-shape, and one side of the bottom end of the lever 204 is welded to the top end of the rotating plate 203 in an integrated structure. By using the welded inverted L-shaped lever 204, the structural strength of the connection between the rotating plate 203 and the lever 204 is improved.

[0034] In this embodiment, the rubber pad 205 has a right trapezoidal cross-section and is symmetrically distributed about the transverse central axis of the fixing groove 201. The right trapezoidal rubber pad 205 improves the tightness and firmness of the engagement between the rotating plate 203 and the inner wall of the fixing groove 201.

[0035] Example 2

[0036] Based on Example 1, a preferred embodiment of the double-spiral mixing tank for preparing fire-retardant coatings provided by this utility model is as follows: Figures 1 to 6As shown: The vibrating discharge assembly 8 includes a chute 809, which is located on one side of the bottom of the tank 5. A slide rod 805 is fixedly connected to the inner wall of the chute 809. A return spring 808 is wound around one side of the surface of the slide rod 805. A slider 807 is slidably connected to the surface of the slide rod 805 at one end of the return spring 808. A sliding plate 802 is fixedly connected to the bottom end of the slider 807. Flexible blocks 801 are fixedly connected at equal intervals on one side of the sliding plate 802. A drive is fixedly connected at the middle position on the other side of the sliding plate 802. A micro drive motor 806 is fixedly connected to the bottom end of the tank body 5 on one side of the slide 809. The output end of the micro drive motor 806 is fixedly connected to the cam 804 through a coupling. By starting the micro drive motor 806, the cam 804 is driven to rotate and periodically contact the drive block 803. The elastic force of the return spring 808 is used to make the flexible block 801 slide back and forth to collide with the discharge pipe 7, so as to realize the vibration anti-blocking of the discharge pipe 7 and avoid the fireproof coating from blocking the discharge pipe 7 and affecting the discharge rate.

[0037] In this embodiment, one side of the flexible block 801 is arc-shaped. The flexible block 801 is fixedly connected to one side of the sliding plate 802 by bolts. The arc-shaped flexible block 801 makes it easier for it to collide and contact with the surface of the discharge pipe 7.

[0038] In this embodiment, the top view of the drive block 803 is arc-shaped. The drive block 803 and the cam 804 are on the same horizontal plane. The arc-shaped drive block 803, which is on the same horizontal plane as the cam 804, makes it easier for the slide plate 802 to slide by rotating into contact with the cam 804.

[0039] Furthermore, the mounting component 3 includes a locking block 302, which is fixedly connected to the output end of the servo motor 1 via a coupling. The bottom end of the locking block 302 has a locking groove 305, and a mounting bolt 304 is movably connected to one side of the locking block 302. The top end of the spiral stirring rod 4 is fixedly connected to a mounting base 301, and a bolt hole 303 with a threaded engagement with the mounting bolt 304 is provided on one side of the mounting base 301. By utilizing the locking between the mounting base 301 and the locking groove 305, and by utilizing the threaded engagement between the mounting bolt 304 and the bolt hole 303, the spiral stirring rod 4 can be disassembled and assembled with the locking block 302, making it convenient to disassemble the spiral stirring rod 4 for thorough cleaning, maintenance, or replacement.

[0040] In this embodiment, the mounting base 301 and the slot 305 form an engaging structure. The cross-sectional shape of the mounting base 301 and the slot 305 is T-shaped. By utilizing the engaging structure between the T-shaped mounting base 301 and the slot 305, the firmness and stability of the engaging installation between the spiral stirring rod 4 and the locking block 302 are improved.

[0041] In addition, a guide platform 6 is fixedly connected to the inner bottom wall of the tank body 5. The guide platform 6 is funnel-shaped. By using the funnel-shaped guide platform 6, the material inside the tank body 5 can be discharged more concentratedly through the discharge pipe 7.

[0042] The working principle and usage process of this utility model are as follows: First, the raw materials are added into the tank 5 through the feeding hopper 10. Then, the servo motor 1 is started to drive the spiral stirring rod 4 to rotate. The two servo motors 1 make the spiral stirring rod 4 rotate in opposite directions, so that one spiral stirring rod 4 can convey the material to the lower end of the tank 5, while the other spiral stirring rod 4 conveys it upward, so that the material inside the tank 5 can be mixed faster and more evenly. After mixing, the valve on the discharge pipe 7 can be opened to discharge the material.

[0043] During the discharge process of the discharge pipe 7, the micro drive motor 806 can be activated to drive the cam 804 to rotate, periodically contacting the drive block 803. This causes the sliding plate 802 to slide and drive the slider 807 to slide on the surface of the slide rod 805 to compress the reset spring 808, and drive the flexible block 801 to slide and impact the surface of the discharge pipe 7. After the cam 804 rotates away, the elastic force of the reset spring 808 causes the slider 807 to slide and drive the sliding plate 802 and the flexible block 801 to return to their original positions. In this way, the back-and-forth sliding of the flexible block 801 can collide with the discharge pipe 7, thereby achieving vibration prevention and anti-blocking of the discharge pipe 7.

[0044] Meanwhile, when the material discharge is completed and other specifications of fireproof coatings need to be prepared, the rotating plate 203 can be rotated by turning the lever 204 until it is completely separated from the inside of the fixed groove 201. Then, the staff can open it through the handle at the top of the top cover 9, which makes it easier to clean the inner wall of the tank 5 and avoid residual materials from affecting the preparation of other fireproof coatings. During installation, the top cover 9 is prepared to be locked into the top of the inside of the tank 5 by using the engagement between the limiting block 202 and the limiting groove 206. Then, the lever 204 is turned so that the rotating plate 203 rotates and locks into the inside of the fixed groove 201. The rubber pad 205 is used to improve the tightness of the engagement of the rotating plate 203, so as to achieve a firm installation between the top cover 9 and the tank 5.

[0045] Furthermore, after the top cover 9 is opened, the mounting base 301 and the slot 305 can be engaged, and the mounting bolt 304 and the bolt hole 303 can be threaded together to allow the spiral stirring rod 4 and the locking block 302 to be disassembled, making it easy to disassemble the spiral stirring rod 4 for thorough cleaning, maintenance or replacement.

[0046] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
