Description

Technical Field

[0001] The invention relates to the technical field of mixer production, in particular to a mixer. Background Art

[0002] Mixing is a very important task in production. The quality of the mixing process directly affects the final quality of the product. For example, when using a mixer to produce refractory materials such as magnesia carbon bricks, the mixing order and feeding method of the mixer should be as follows: first add coarse particles and medium particles, stir for a period of time, then add resin, stir for a period of time, then add graphite, stir for a period of time, and finally add fine powder and various additives, and then stir evenly. The added resin is mainly liquid phenolic resin, which is mainly used as a binder.

[0003] When the existing mixer is mixing, the smaller the particle size of some raw materials, the easier they are to absorb moisture. Since it is difficult to completely avoid moisture in the production and storage environment, a small part of some raw materials will condense into small clumps after being damp. These clumps of raw materials are small in size and dispersed in the materials. When mixing, the existing mixer simply relies on the stirring shaft to disperse them, which is inefficient and takes a long time, prolonging the mixing time. In addition, when the existing mixer adds resin, its adding method is mainly to pour the resin directly. This adding method will cause the poured resin to be mainly absorbed by the material at the landing point. This part of the material absorbs too much resin. In the subsequent mixing process, the mixing time needs to be further extended to allow the resin to be dispersed, further extending the mixing time, and it is very likely that some materials will absorb too much resin. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art that small materials that are damp and clumped are difficult to disperse and the resin adding efficiency is low, and to propose a mixer.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Example 1: Reference Figure 1-Figure 7 , Figure 10-12 A mixer includes a mixing barrel 1, which is arranged horizontally, and two brackets are fixed at the bottom of the mixing barrel 1. A feeding pipe 14 is provided at the top of the mixing barrel 1, and a discharge port is provided at the bottom of the mixing barrel 1. A hatch 13 is installed on the discharge port. The feeding pipe 14 is arranged at the top of the mixing barrel 1, and the feeding pipe 14 can be directly connected to the feeding machine, making feeding more convenient. The discharge port and the hatch 13 are arranged at the bottom. After the mixing is completed, the hatch 13 is directly opened, and the mixed materials are directly discharged. A driving shaft 2 is coaxially installed in the mixing barrel 1, and the driving shaft 2 is connected to a motor 15. A connecting plate 3 is fixedly installed on both sides of the driving shaft 2 in the mixing barrel 1. The connecting plate 3 is semicircular and coaxially arranged with the driving shaft 2. A lifting plate 4 is arranged on both sides of the driving shaft 2, and both ends of the lifting plate 4 are fixedly connected to the corresponding connecting plate 3; the main function of the lifting plate 4 is to lift the material in the mixing barrel 1 upward. The outer surface of the connecting plate 3 in contact with the mixing barrel 1 is provided with a wear-resistant coating. Since the outer surface of the connecting plate 3 and the mixing barrel 1 are in friction for a long time, a wear-resistant coating needs to be provided, and a ceramic particle coating is preferably used.

[0019] A plurality of steel wires 7 are correspondingly arranged in the mixing barrel 1 above the driving shaft 2. One end of the steel wires 7 is fixed on the elastic connection mechanism, which is elastically connected to the mixing barrel 1 with the elastic connection mechanism. The other end of the steel wires 7 is fixed on the feeding mechanism, which is fixed on the mixing barrel 1. The height of the feeding mechanism is higher than the height of the elastic connection mechanism. The feeding mechanism is used to transport the resin to the steel wires 7. It also includes a shaking mechanism, which is transmission-connected with the elastic connection mechanism. The shaking mechanism is used to reciprocate the elastic connection mechanism so that the elastic connection mechanism drives the steel wires 7 to shake. Since one end of the steel wire 7 is fixed and the other end is elastically connected, the shaking mechanism can reciprocate the elastic connection mechanism to make the steel wires 7 present an irregular shaking state, so that when the falling materials come into contact with the steel wires 7, they can be dispersed by the shaking steel wires 7, so that each material in the material can be changed from large particles to small particles, which is more conducive to uniform mixing.

[0020] The steel wires 7 are arranged in a dot matrix and staggered. The dot matrix and staggered arrangement make it possible for the material to collide with the steel wires 7 with a greater probability during the falling process, so as to prevent the material from falling directly from the gaps between the steel wires 7. The steel wires 7 are made of alloy steel, and the diameter is controlled at 0.3-0.4 mm. Alloy steel has good toughness, and a smaller diameter can obtain a better dispersion effect and reduce the adhesion of the material.

[0021] The elastic connection mechanism includes a magnetic attraction plate 8 and a spring 10. The steel wire 7 is fixedly connected to the front side of the magnetic attraction plate 8. The rear side of the magnetic attraction plate 8 is connected to the mixing barrel 1 through the spring 10. The shaking mechanism includes two magnetic blocks 16 . A magnetic block 16 is fixed to each of the two ends of the connecting plate 3 below the magnetic attraction plate 8 . The magnetic blocks 16 are attracted to the magnetic attraction plate 8 .

[0022] The advantage of the shaking mechanism is that, by utilizing the movement characteristics of the connecting plate 3 itself, the two magnetic blocks 16 on the connecting plate 3 can intermittently interact with the magnetic attraction plate 8 from both sides during the movement of the connecting plate 3, so that the magnetic attraction plate 8 can be pulled backward and slightly offset to both sides, so that the magnetic attraction plate 8 can pull the steel wire 7 and make the steel wire 7 swing slightly, making the shaking amplitude of the steel wire 7 larger. And due to the movement characteristics of the connecting plate 3, when the two sides of the connecting plate 3 move to the top, the material is just lifted up by the connecting plate 3 and falls down, and the shaking mechanism just shakes, realizing the effective coordination between the two.

[0023] The magnetizing plate 8 is rectangular and made of martensitic stainless steel, which has high corrosion resistance and can also be magnetically attracted to the magnetic block 16.

[0024] A plurality of stirring shafts 5 are arranged around the driving shaft 2 between the two connecting plates 3, and both ends of the stirring shafts 5 are rotatably connected to the corresponding connecting plates 3. By arranging a plurality of stirring shafts 5, when the two connecting plates 3 make reciprocating motion, the plurality of stirring shafts 5 can be synchronously rotated to further stir and mix the materials.

[0025] Example 2: Reference Figure 8-Figure 9 As another preferred embodiment of the present invention, the difference from Embodiment 1 is that the feeding mechanism includes a storage body 6, a cavity 11 is opened in the storage body 6, the corresponding end of the steel wire 7 is fixedly connected to the front side of the storage body 6, a feeding pipe 9 is fixed on the rear side of the storage body 6, the feeding pipe 9 is connected with the cavity 11, and the feeding pipe 9 is used to connect with the resin supply device. A plurality of insertion holes 12 are also opened on the front side of the storage body 6, and the insertion holes 12 correspond to the steel wires 7 one by one. The corresponding ends of the steel wires 7 are inserted into the insertion holes 12 and fixed, and the inner diameter of the insertion holes 12 is larger than the diameter of the steel wire 7.

[0026] The inner wall of the cavity 11 is sprayed with anti-stick coating. Anti-stick coating can prevent excessive resin adhesion and residue. When the feeding mechanism is in use, after the resin enters the cavity 11 through the feeding pipe 9, the inner diameter of the plug hole 12 is larger than the diameter of the steel wire 7, so that the resin can flow out through the gap between the steel wire 7 and the plug hole 12. Due to the guiding effect of the steel wire 7 and the steel wire 7 being tilted downward, the outflowing resin will flow downward along the steel wire 7, so that the surface of the steel wire 7 is attached with resin. When the steel wire 7 shakes, these resins are shaken off into many small droplets, which are synchronously fully combined with the falling materials. The steel wire can shake off the materials adhering to it through high-frequency vibration.

[0027] The overall workflow of the present invention is as follows: The prepared coarse particles and medium particles are put into the mixing barrel 1 through the feeding pipe 14, and then the motor 15 is started, and the motor 15 drives the driving shaft 2 to rotate back and forth, and the driving shaft 2 drives two connecting plates 3, two lifting plates 4, and a plurality of stirring shafts 5 to rotate back and forth in the mixing barrel 1, so that the raw materials of each component in the mixing barrel 1 can be fully stirred and mixed. In the subsequent stirring and mixing process, the remaining additives are added in sequence through the feeding pipe 14; In the above process, when the two lifting plates 4 make reciprocating motion, a part of the material in the mixing barrel 1 will be lifted up, and in the process of falling, it will pass through the area formed by the multiple steel wires 7. At this time, due to the two magnetic blocks 16 provided on the connecting plate 3, in the process of following the movement of the connecting plate 3, they will intermittently interact with the magnetic plate 8 to make the magnetic plate 8 elastically connected to the mixing barrel 1 drive the multiple steel wires 7 to synchronously shake at a high frequency, so that the falling material will be dispersed by the high-frequency shaking steel wires 7 when it contacts with the steel wires 7, so that some agglomerated materials can be dispersed into small particles, thereby achieving more uniform mixing of the materials; At the same time, when it is necessary to add resin to the material in the mixing barrel 1, the motor 15 needs to be stopped so that the steel wire 7 does not shake. At this time, the resin supply device is started, and the resin is input into the cavity 11 of the storage body 6 through the feed pipe 9. The resin in the cavity 11 overflows through the gap between the steel wire 7 and the socket 12, and flows downward along the inclined steel wire 7, so that the surface of the steel wire 7 is covered with resin. Then the motor 15 is started again to make the steel wire 7 continue to shake. During the shaking process, the resin on its surface will be vibrated into many small droplets and fall. At this time, the material lifted and fallen by the connecting plate 3 will be fully and evenly mixed with the shaken-off resin droplets, further accelerating the mixing efficiency and making the mixing effect more uniform.

[0028] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
