Description

Technical Field

[0001] This utility model relates to the field of raw material mixing technology, specifically a raw material mixing device. Background Technology

[0002] Foam extinguishing agents are effective extinguishing agents for flammable and combustible liquids. They mainly generate a coagulated foam floating layer on the surface of the liquid, which has a suffocating and cooling effect. When used, foam is generated through mechanical action or chemical reaction to extinguish the fire. In the production process of foam extinguishing agents, a mixing device is generally required to mix the various raw materials of the foam extinguishing agent together.

[0003] When using a foam extinguishing agent raw material mixing device, after a batch of foam extinguishing agent has been produced, it is sometimes necessary to clean the inside of the device. However, since the mixing device is usually a closed tank and some tanks are relatively large, if the inside of the tank is cleaned repeatedly, a large amount of water is required and a long time is spent waiting for the water to be injected. Utility Model Content

[0004] The purpose of this invention is to provide a raw material mixing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A raw material mixing device includes a mixing tank with four support columns fixedly connected to its bottom surface. A feed pipe connects to the top of the mixing tank, and a discharge pipe connects to its bottom. Several stirring rings are arranged inside the mixing tank, and several stirring rods are fixedly connected to each stirring ring. A baffle is located inside the mixing tank at the top inner side, and a U-shaped frame is fixedly connected to the baffle and slidably connected to the mixing tank. An electric telescopic rod is installed at the top of the mixing tank, and a mounting base is fixedly connected to the top of the mixing tank. The electric telescopic rod is fixedly mounted on the mounting base, and its output end is drivenly connected to the U-shaped frame. An elliptical rod is arranged between two adjacent stirring rings, with its top end slidably connected to the adjacent stirring ring and its bottom end fixedly connected to the adjacent stirring ring. An elliptical groove is formed on the top surface of each stirring ring, and the top end of the elliptical rod is slidably connected to the interior of the adjacent elliptical groove. The elliptical rod has a hollow structure.

[0007] Furthermore, a conveying box is fixedly connected to the side of the mixing tank, and a conveying pump is installed inside the conveying box. The water inlet of the conveying pump is connected to a connecting pipe one that is connected to the bottom of the mixing tank, and the water outlet of the conveying pump is connected to a connecting pipe two that is connected to the feed pipe.

[0008] Furthermore, a drive box is fixedly connected to the bottom of the mixing tank, a drive motor is fixedly connected inside the drive box, and a drive shaft that is rotatably connected to the output end of the drive motor is driven by the drive shaft. The top end of the drive shaft is fixedly connected to the bottom of the adjacent stirring ring, and the top end of the drive shaft is fixed to the bottom surface of the stirring ring located at the bottom.

[0009] Furthermore, valves are installed inside both the feed pipe and the discharge pipe.

[0010] Furthermore, the mixing tank is equipped with a limiting rod that passes through the inside of the baffle. The bottom end of the limiting rod is fixedly connected to the top of the adjacent stirring ring. A fixing ring is fixedly connected to the top of the mixing tank.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5In this embodiment of the present invention, a raw material mixing device includes a mixing tank 10. Four support columns 13 are fixedly connected to the bottom of the mixing tank 10, providing support for the mixing tank 10. An inlet pipe 11 is connected to the top of the mixing tank 10, and an outlet pipe 12 is connected to the bottom of the mixing tank 10. Valves are installed inside both the inlet pipe 11 and the outlet pipe 12. Several stirring rings 40 are installed inside the mixing tank 10, and several stirring rods 41 are fixedly connected to the stirring rings 40. A baffle 70 is installed inside the mixing tank 10, located at the top inner side of the mixing tank 10. A U-shaped frame 71 is fixedly connected to the baffle 70 and slidably connected to the mixing tank 10. A [missing information - likely a design element] is installed at the top of the mixing tank 10. An electric telescopic rod 16 is fixedly connected to the top of the mixing tank 10, and the electric telescopic rod 16 is fixedly mounted on the mounting base. The output end of the electric telescopic rod 16 is connected to the U-shaped frame 71 for transmission. An elliptical rod 50 is provided between two adjacent stirring rings 40. The top end of the elliptical rod 50 is slidably connected to the adjacent stirring ring 40, and the bottom end of the elliptical rod 50 is fixedly connected to the adjacent stirring ring 40. Two adjacent stirring rings 40 are connected by corresponding elliptical rods 50. An elliptical groove is opened on the top surface of the stirring ring 40. The top of the elliptical rod 50 is slidably connected to the inside of the adjacent elliptical groove. The elliptical rod 50 only slides along the inside of the elliptical groove and only slides up and down relative to the stirring ring 40. The elliptical rod 50 has a hollow structure.

[0024] A drive box 20 is fixedly connected to the bottom of the mixing tank 10. A drive motor 21 is fixedly connected inside the drive box 20. The output end of the drive motor 21 is connected to a drive shaft 22 that is rotatably connected to the mixing tank 10. The top end of the drive shaft 22 is fixedly connected to the bottom of the adjacent stirring ring 40. The top end of the drive shaft 22 is fixed to the bottom surface of the stirring ring 40 located at the bottom. The drive shaft 22 can support and limit the stirring ring 40 located at the bottom.

[0025] Specifically, after closing the valve inside the discharge pipe 12, various raw materials for foam extinguishing agent can be introduced into the mixing tank 10 through the feed pipe 11. The raw materials can pass through the gap between the baffle 70 and the inner wall of the mixing tank 10 and enter the bottom of the mixing tank 10. Then, the drive shaft 22 can be rotated by the drive motor 21. The drive shaft 22 can drive the stirring ring 40 located at the bottom to rotate. Since the cross-section of the elliptical rod 50 is elliptical, the bottom stirring ring 40 can drive the top stirring ring 40 to rotate through the elliptical rod 50 at its top, thereby causing several stirring rings 40 to rotate synchronously. The stirring ring 40 can drive the stirring rod 41 to rotate, and the raw materials are stirred by the stirring rod 41, so that the various raw materials are mixed inside the mixing tank 10. After the stirring is completed, the valve inside the discharge pipe 12 can be opened to discharge the material through the discharge pipe 12. After closing the valve inside the discharge pipe 12 again, the raw materials can be injected into the mixing tank 10 again, and then stirred again.

[0026] When it is necessary to clean the inside of the mixing tank 10, the U-shaped frame 71 can be moved upward by the electric telescopic rod 16. The U-shaped frame 71 can drive the baffle 70 to move upward, reducing the distance between the edge of the baffle 70 and the arc-shaped inner wall of the top of the mixing tank 10. At this time, clean water can be introduced into the mixing tank 10 through the feed pipe 11. The clean water can pass through the space between the edge of the baffle 70 and the inner wall of the mixing tank 10, and then flow downward along the inner wall of the mixing tank 10, thereby cleaning the inner wall of the mixing tank 10. This allows the cleaning of the mixing tank 10 to start directly, which helps to improve the cleaning speed and does not require filling the inside of the mixing tank 10 with clean water, thus reducing the amount of clean water used.

[0027] Example 1

[0028] like Figure 1 As shown, in this embodiment, a conveying box 30 is fixedly connected to the side of the mixing tank 10. A conveying pump is installed inside the conveying box 30. The water inlet of the conveying pump is connected to a connecting pipe 31 that is connected to the bottom of the mixing tank 10, and the water outlet of the conveying pump is connected to a connecting pipe 32 that is connected to the feed pipe 11.

[0029] In practice, when a certain amount of clean water accumulates inside the mixing tank 10 and the water level overflows the bottom of the connecting pipe 1 31, the conveying pump can draw the clean water from the mixing tank 10 through the connecting pipe 1 31 and send the clean water to the connecting pipe 2 32. Then, the clean water in the connecting pipe 2 32 can re-enter the mixing tank 10 through the feed pipe 11, so that the clean water circulates inside the mixing tank 10 and continuously cleans the inner wall of the mixing tank 10. After cleaning for a certain period of time, the valve in the discharge pipe 12 can be opened to discharge the cleaning water in the mixing tank 10. After closing the valve in the discharge pipe 12, clean water can be introduced into the mixing tank 10 again to repeat the cleaning process.

[0030] When mixing the raw materials, a pump can be used to draw the raw materials from the first connecting pipe 31 into the second connecting pipe 32, and then back into the mixing tank 10 from the feed pipe 11. This allows the raw materials to circulate inside the mixing tank 10, which helps to improve the mixing effect.

[0031] like Figure 2-5As shown, in this embodiment, a limiting rod 60 is provided inside the mixing tank 10, passing through the inside of the baffle 70. An annular component is provided in the middle of the top surface of the baffle 70. The limiting rod 60 passes through the annular component. When clean water falls on the baffle 70, the annular component can prevent the clean water from falling out of the baffle 70. The bottom end of the limiting rod 60 is fixedly connected to the top of the adjacent stirring ring 40. A fixing ring 14 is fixedly connected to the top of the mixing tank 10. A positioning block 61 that is slidably connected to the top of the limiting rod 60 is rotatably connected to the fixing ring 14. A positioning screw 15 that is inserted into the positioning block 61 is screwed into the fixing ring 14. The positioning block 61 can be fixed inside the fixing ring 14 by the positioning screw 15. The bottom end of the limiting rod 60 is provided on the top surface of the stirring ring 40 located at the top. The limiting rod 60 has a hollow structure. An abutment block 51 is fixedly connected to the top of the elliptical rod 50. The bottom surface of the abutment block 51 abuts against the top surface of the adjacent stirring ring 40. The abutment block 51 located at the top is located inside the limiting rod 60.

[0032] In practice, the limiting rod 60 can restrict the position of the top stirring ring 40. The stirring ring 40 can prevent the bottom stirring ring 40 from moving downward through the abutment block 51, thereby fixing the position of several stirring rings 40. When the drive shaft 22 drives several stirring rings 40 to rotate, the top stirring ring 40 can drive the limiting rod 60 to rotate relative to the positioning block 61. When it is necessary to clean the inner wall of the mixing tank 10, the positioning screw 15 can be unscrewed. At this time, the limiting rod 60 and the top stirring rings 40 will move downward, so that the elliptical rod 50 is fitted on the bottom elliptical rod 50, thereby causing several stirring rods 41 to fall to the bottom of the inner side of the mixing tank 10. When a certain amount of clean water accumulates inside the mixing tank 10, the drive motor 21 can drive the stirring ring 40 to rotate back and forth in a small range, so that the stirring rods 41 move in the clean water to clean the stirring rods 41 and the bottom of the mixing tank 10, which is beneficial to improving the cleaning effect inside the mixing tank 10.

[0033] Example 2

[0034] Based on Example 1, such as Figure 5 As shown, in this embodiment, a fixed base 80 is provided on the top of the mixing tank 10. A power motor 82 is fixedly connected inside the fixed base 80. The output end of the power motor 82 is driven by a winding rod 83 that is rotatably connected to the inside of the fixed base 80. A connecting rope 81 is wound around the winding rod 83. The connecting rope 81 extends to the outside of the fixed base 80 and is fixed on the positioning block 61.

[0035] In practice, when the inside of the mixing tank 10 needs to be cleaned, after unscrewing the positioning screw 15, the winding rod 83 can be rotated by the power motor 82, causing the winding rod 83 to release the connecting rope 81. At this time, under the action of gravity, the limiting rod 60, the several stirring rings 40 at the top, and the several elliptical rods 50 will move downward. After the cleaning is completed, the winding rod 83 can be rotated in the opposite direction by the power motor 82, causing the winding rod 83 to wind up the connecting rope 81. In this way, the limiting rod 60 can be pulled upward by the connecting rope 81, so that the limiting rod 60, the several stirring rings 40 at the top, and the several elliptical rods 50 gradually move upward to their original positions. After the positioning block 61 is reinserted into the fixing ring 14, the positioning screw 15 can be screwed back into the fixing ring 14, so that the end of the positioning screw 15 is inserted into the positioning block 61, positioning the positioning block 61 and the limiting rod 60, thereby re-fixing the several stirring rings 40.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
