Description

Technical Field

[0001] This utility model relates to the field of chemical raw material processing technology, and in particular to a mixing device for chemical raw material processing. Background Technology

[0002] Chemical raw materials are the material basis for chemical production. They can be divided into two main categories according to their composition: organic chemical raw materials (such as alkanes, alkenes, and benzene) and inorganic chemical raw materials (such as sulfur, sodium, and phosphorus). They are widely used in plastics, synthetic fibers, and other fields.

[0003] A search revealed a chemical raw material mixing tank (publication number: CN220460419U) on the Chinese Patent Network, comprising a chemical raw material mixing tank with a transmission box bolted to its top. Raw materials are poured in through the feed inlet on the top left side of the mixing tank 1. The power supply to the reduction motor 4 is connected, and the reduction motor 4 is fixed to the mixing tank 1. The reduction motor 4 drives the crankshaft 5 to rotate. The crankshaft 5 is rotatably connected to the transmission box 3 via bearings to ensure the smooth rotation of the crankshaft 5. The crankshaft 5 drives the large impeller 21 to rotate, which in turn drives the transmission belt 22 to rotate. The transmission belt 22 drives the small impeller 23 to rotate, which in turn drives the stirring sleeve 10 to rotate. The stirring sleeve 10 can rotate the chemical raw material mixing tank. The raw materials inside the chemical raw material mixing tank 1 are stirred. The crankshaft 5 can drive the transmission frame 6 to move left and right using its structure. When the transmission frame 6 is driven to move to the left, the transmission frame 6 can drive the rack 7 to move to the left. The rack 7 can drive the gear shaft 8 to rotate. The gear shaft 8 is rotatably set with the mixing sleeve 10 through the bearing. The gear shaft 8 can drive the scraper frame 9 to rotate. The rotating scraper frame 9 can scrape and clean the inner wall of the chemical raw material mixing tank 1 to prevent the raw materials from sticking to the inner wall of the chemical raw material mixing tank 1 and reduce residue during unloading.

[0004] The application uses a scraper frame to scrape and clean the inner wall of the mixing tank, which can reduce raw material residue. However, during the feeding process, some raw materials are in a clumped solid state. After entering the mixing tank, due to the large amount of liquid raw materials, the clumped solid raw materials are not subjected to much impact force from the mixing arm in the liquid raw materials, and cannot be broken up. Therefore, the mixing effect of the raw materials is poor, and there is room for improvement. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mixing device for processing chemical raw materials.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A mixing device for processing chemical raw materials includes a mixing cylinder. A mixing component is fixedly connected to the bottom end of the mixing cylinder. The mixing component includes a first servo motor. A circular rod is fixedly connected to the output end of the first servo motor. The circular rod is fixedly connected to the output shaft of the first servo motor via a coupling. Several stirring arms are fixedly connected to the surface of the circular rod. A discharge pipe is connected to the bottom end of the mixing cylinder. A sealing cap is threadedly connected to the bottom end of the discharge pipe. An end cap is fixedly connected to the top end of the mixing cylinder via two locking bolts. A feed hopper is fixedly connected to the upper surface of the end cap. A pretreatment component is fixedly connected to the upper surface of the end cap. The pretreatment component includes a second servo motor. A drive shaft is fixedly connected to the output end of the second servo motor. The drive shaft is fixedly connected to the output shaft of the second servo motor via a coupling. A rotating crushing arm is fixedly connected to the bottom end of the drive shaft. A circular frame is fixedly connected to the inner wall of the mixing cylinder. A feed inlet and a circular hole are respectively opened on the upper surface of the circular frame. A discharge outlet is opened on the lower surface of the circular frame. Extrusion mechanisms are fixedly connected to corresponding positions on the upper and lower surfaces of the circular frame.

[0008] Preferably, the bottom end of the mixing cylinder has a through hole adapted to the circular rod, the top end of the circular rod extends into the interior of the mixing cylinder and is rotatably connected to the lower surface of the circular frame, and the top end of the circular rod is restricted by the lower surface of the circular frame, so that it can rotate stably inside the mixing cylinder.

[0009] Preferably, the position of the feed hopper corresponds to the position of the feed inlet, and the bottom of the feed hopper extends into the interior of the feed inlet. The position of the feed inlet does not correspond to the position of the discharge outlet. Therefore, the raw materials entering through the feed inlet will remain on the inner wall of the circular frame in the first time and will not be discharged directly from the discharge outlet.

[0010] Preferably, the drive shaft is adapted to the circular hole, the bottom end of the drive shaft extends through the circular hole into the interior of the circular frame, and the rotating crushing arm is rotatably connected to the inner wall of the circular frame.

[0011] Preferably, the extrusion mechanism includes strip frames, and two positioning rods are fixedly connected to the inner walls of the two strip frames away from the circular frame. A limiting circular plate is fixedly connected to one end of the positioning rod away from the inner wall of the strip frame. A spring is sleeved on the surface of the positioning rod. Strip-shaped through holes are opened on the upper and lower surfaces of the circular frame at positions corresponding to the strip frames.

[0012] Preferably, the left and right inner walls of the strip frame are slidably connected to movable plates, the two movable plates are slidably connected to the surfaces of the two positioning rods respectively, and the opposite surfaces of the two movable plates are fixedly connected to trapezoidal compression blocks, and the two ends of the spring overlap the inner wall of the strip frame and the movable plates respectively.

[0013] Preferably, the positions of the two trapezoidal extrusion blocks are the same as the positions of the rotating crushing arm, and the two trapezoidal extrusion blocks are slidably connected to the inner walls of the two strip-shaped through holes respectively.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. By setting up the pretreatment components, during use, the rotating crushing arm can rotate inside the circular frame and cooperate with the two trapezoidal extrusion blocks to crush the agglomerated solid raw materials inside the circular frame. This avoids the situation where the agglomerated solids cannot be crushed and dispersed by the stirring arm in the mixing drum, thereby ensuring the mixing effect of the raw materials entering the mixing drum and increasing the mixing quality of the raw materials.

[0016] 2. Through the setting of positioning rod, movable plate and spring, after the rotating crushing arm squeezes the two trapezoidal extrusion blocks to make them move away from each other, the two springs can generate reaction force to drive the trapezoidal extrusion blocks to move closer to each other again. This allows the rotating crushing arm to repeatedly cooperate with the trapezoidal extrusion blocks to perform cyclic crushing of agglomerated solid raw materials. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1, referring to Figure 1-5 A mixing device for processing chemical raw materials includes a mixing cylinder 1. A mixing component 2 is fixedly connected to the bottom end of the mixing cylinder 1. The mixing component 2 includes a first servo motor 201. A circular rod 202 is fixedly connected to the output end of the first servo motor 201. A plurality of stirring arms 203 are fixedly connected to the surface of the circular rod 202. A discharge pipe 204 is connected to the bottom end of the mixing cylinder 1. A sealing cap 205 is threadedly connected to the bottom end of the discharge pipe 204. An end cap 4 is fixedly connected to the top end of the mixing cylinder 1 by two locking bolts 3. The upper surface of the end cap 4 is fixedly connected to... The feed hopper 5 is connected to the upper surface of the end cover 4, and a pretreatment component 6 is fixedly connected to the upper surface of the end cover 4. The pretreatment component 6 includes a second servo motor 601. The output end of the second servo motor 601 is fixedly connected to a drive shaft 602. The bottom end of the drive shaft 602 is fixedly connected to a rotating crushing arm 603. A circular frame 604 is fixedly connected to the inner wall of the mixing cylinder 1. The upper surface of the circular frame 604 is provided with a feed port and a circular hole, and the lower surface of the circular frame 604 is provided with a discharge port. Extrusion mechanisms are fixedly connected to the corresponding positions on the upper and lower surfaces of the circular frame 604.

[0025] The bottom end of the mixing cylinder 1 is provided with a through hole that is adapted to the circular rod 202. The top end of the circular rod 202 extends into the interior of the mixing cylinder 1 and is rotatably connected to the lower surface of the circular frame 604. The position of the feed hopper 5 corresponds to the position of the feed inlet. The bottom end of the feed hopper 5 extends into the interior of the feed inlet. The drive shaft 602 is adapted to the circular hole. The bottom end of the drive shaft 602 passes through the circular hole and extends into the interior of the circular frame 604. The rotating crushing arm 603 is rotatably connected to the inner wall of the circular frame 604.

[0026] The raw material enters the circular frame 604 through the feed hopper 5. After being processed by the extrusion mechanism, it enters the mixing cylinder 1 through the discharge port on the lower surface of the circular frame 604. At this time, the first servo motor 201 can drive the stirring arm 203 to rotate through the circular rod 202. The stirring arm 203 can stir and mix the raw material. After the stirring is completed, the sealing cover 205 is opened to discharge the raw material from the discharge pipe 204.

[0027] Example 2: The extrusion mechanism includes strip frames 605. Two positioning rods 606 are fixedly connected to the inner walls of the two strip frames 605 away from the circular frame 604. One end of the positioning rod 606 away from the inner wall of the strip frame 605 is fixedly connected to a limiting circular plate 607. A spring 608 is sleeved on the surface of the positioning rod 606. Strip-shaped through holes are opened on the upper and lower surfaces of the circular frame 604 at positions corresponding to the strip frames 605. Movable plates 609 are slidably connected to the left and right inner walls of the strip frames 605. The two movable plates 609 are slidably connected to the surfaces of the two positioning rods 606 respectively. Trapezoidal extrusion blocks 610 are fixedly connected to the opposite surfaces of the two movable plates 609. The two ends of the spring 608 overlap with the inner wall of the strip frame 605 and the movable plate 609 respectively. The positions of the two trapezoidal extrusion blocks 610 are the same as the positions of the rotating crushing arm 603. The two trapezoidal extrusion blocks 610 are slidably connected to the inner walls of the two strip-shaped through holes respectively.

[0028] The second servo motor 601 can drive the rotating crushing arm 603 to rotate within the circular frame 604 via the transmission shaft 602, thereby scraping the raw material entering the circular frame 604 towards the feed port. When the rotating crushing arm 603 contacts the two trapezoidal extrusion blocks 610, the liquid can pass through the gap, while the agglomerated solid can be crushed by the rotating crushing arm 603 and the two trapezoidal extrusion blocks 610. The liquid flows out from the feed port to the mixing cylinder 1 along with the liquid raw material. After the inclined sides of the two trapezoidal extrusion blocks 610 are squeezed, they move away from each other and squeeze the spring 608 on the surface of the positioning rod 606 through the movable plate 609. At this time, the two rotating crushing arms 603 can pass between the two trapezoidal extrusion blocks 610 and recycle the raw material for conveying and crushing. This can pre-crush the agglomerated solid, thereby improving the mixing effect of the raw material.

[0029] Working Principle: First, the chemical raw materials are poured into the circular frame 604 through the feed hopper 5. After entering the circular frame 604, the raw materials remain inside. At this time, the second servo motor 601 drives the rotating crushing arm 603 to rotate at a constant speed through the transmission shaft 602. The rotating crushing arm 603 scrapes the raw materials on the inner wall of the circular frame 604 and moves them towards the position between the two trapezoidal extrusion blocks 610. When the rotating crushing arm 603 contacts the two trapezoidal extrusion blocks 610, liquid can pass through the gap, while the agglomerated solids can be crushed by the rotating crushing arm 603 and the two trapezoidal extrusion blocks 610. The rotating crushing arm 603 can squeeze the inclined side of the two trapezoidal extrusion blocks 610, thereby driving... Two trapezoidal extrusion blocks 610 are spaced far apart. The trapezoidal extrusion blocks 610 can drive the springs 608 on the surface of the two positioning rods 606 through the two movable plates 609. At the same time, the rotating crushing arm 603 passes between the two trapezoidal extrusion blocks 610. At this time, the crushed raw materials and liquid raw materials can enter the mixing cylinder 1 through the feed port. The rotating crushing arm 603 then circulates to convey and extrude the raw materials again. After the raw materials enter the mixing cylinder 1, the first servo motor 201 can drive the stirring arm 203 to rotate through the circular rod 202, thereby achieving the stirring and mixing treatment of the raw materials. This can effectively solve the problem that the stirring arm 203 is too large to break up the clumps of raw materials, and further improve the stirring and mixing effect of the raw materials.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
