Description

Technical Field

[0001] The invention relates to the technical field of composite bentonite production, in particular to a composite bentonite mixing device. Background Art

[0002] Composite bentonite is a composite material made by mixing bentonite with other materials (such as polymers, fibers, minerals, etc.). Bentonite itself is a natural clay mineral with montmorillonite as the main component, which has excellent water absorption, expansion, adsorption and ion exchange capacity.

[0003] During the production process of composite bentonite, the composite bentonite material is introduced into the mixing equipment for mixing processing. The composite bentonite is mixed by the cooperation of the stirring piece and the shell. During mixing, the shell is generally in a fixed state. The composite bentonite is introduced into the shell. When the shell is vertically set, the mixing effect of the composite bentonite at the bottom corners is poor. When the shell is horizontally set, the mixing effect of the composite bentonite at the two end corners of the shell is poor. When the shell is tilted, the mixing effect of the composite bentonite at the low end corners of the shell is poor. Since the position of the stirring piece and the composite bentonite in the shell is relatively fixed, the mixing effect of the composite bentonite at the end corners of the shell is poor. At the same time, since the bentonite has strong adsorption and friction occurs between the composite bentonite and the shell during stirring, the friction between the bentonite particles generates static electricity, causing the bentonite to agglomerate, thereby reducing the mixing effect of the bentonite. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art in that the positions of the stirring element and the composite bentonite in the shell are relatively fixed, resulting in poor mixing effect of the composite bentonite at the end corners of the shell, and the bentonite particles are easily agglomerated during the stirring process. A composite bentonite mixing device is proposed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0024] 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.

[0025] Example 1: Reference Figure 1-3, a composite bentonite mixing device includes a base frame 1, the upper end of the base frame 1 is rotatably connected to a shell body 2, one side of the upper end of the shell body 2 is connected to a feed pipe, one end of the shell body 2 is connected to a discharge pipe, and the shell body 2 is connected to a stirring member 3 for mixing materials, and the base frame 1 is rotatably connected to an electric telescopic rod 4 for driving the shell body 2 to rotate. A strip hole 5 is opened on the base frame 1, and a rocker 6 is rotatably connected to the strip hole 5 through a connecting shaft. Both ends of the rocker 6 are arc structures, and a spring 9 is fixedly connected to the lower surface of the rocker 6. One end of the spring 9 is fixedly connected to the base frame 1, and both sides of the upper end of the rocker 6 are fixedly connected to a first connecting rod 7, and the upper end of each first connecting rod 7 is fixedly connected to a first sphere 8, and the bottom end of the shell 2 is fixedly connected to a spacing control member 10, and a pressing plate 11 is fixedly connected to the spacing control member 10, and one end of the pressing plate 11 contacts the upper part of one end of the rocker 6.

[0026] Working principle:

[0027] The bentonite to be mixed is poured into the shell 2 through the feed pipe, and the stirring member 3 is started to stir the bentonite in the shell 2. At the same time, the electric telescopic rod 4 is started to drive the shell 2 to swing back and forth, so that the shell 2 tilts back and forth. During the reciprocating tilting process of the shell 2, the internal bentonite moves back and forth along the length direction of the shell 2, so that the bentonite at the end flows to the middle area of the shell 2, so that the position of the bentonite at the end corners is moved, and the relative position between the bentonite in the shell 2 and the stirring member 3 is changed. During the rotation of the stirring member 3, the moving bentonite is mixed, thereby improving the mixing effect of the bentonite at the end corners;

[0028] When the telescopic end of the electric telescopic rod 4 pushes one end of the shell 2 to rotate upward, the end of the shell 2 located at the discharge pipe rotates downward, and the shell 2 drives the spacing control member 10 to rotate downward, and the spacing control member 10 drives the pressure plate 11 to rotate downward. During the downward rotation of the pressure plate 11, one end of the rocker plate 6 is squeezed, and the pressed end of the rocker plate 6 rotates downward around the connecting shaft, and the pressed end of the rocker plate 6 rotates downward and squeezes the spring 9. The spring 9 generates an elastic force after being compressed, and after the pressed end of the rocker plate 6 rotates downward, it drives the first ball 8 to rotate through the first connecting rod 7. As the shell 2 is located at one end of the discharge pipe continues to rotate downward, the pressure plate 11 continues to squeeze the rocker plate 6. After the end of the shell 2 located at the discharge pipe rotates downward by a certain angle, the pressure plate 11 separates from the rocker plate 6, and under the elastic force of the spring 9, the rocker plate 6 is pushed to rotate upward and reset. The rocker plate 6 drives the first ball 8 to rotate upward through the first connecting rod 7. After the first ball 8 rotates upward by a certain angle, it collides with the bottom end of the shell 2, and the vibration generated by the collision is transmitted to the bentonite.

[0029] When the electric telescopic rod 4 pulls one side of the shell 2 to rotate downward, the shell 2 is located at one end of the discharge pipe and rotates upward, and the shell 2 drives the spacing control member 10 to rotate upward, and the spacing control member 10 drives the pressure plate 11 to rotate upward. During the upward rotation of the pressure plate 11, the rocker 6 is gradually pushed. The pushed end of the rocker 6 rotates upward around the connecting shaft, and the pushed end of the rocker 6 rotates upward after the spring 9 is stretched. After the spring 9 is pulled, an elastic force is generated, and the end of the rocker 6 away from the pressure plate 11 rotates downward, and the end of the rocker 6 away from the pressure plate 11 drives the first ball 8 to rotate downward through another first connecting rod 7. As the shell 2 continues to rotate upward at one end of the discharge pipe, the rocker 6 is continuously pushed by the pressure plate 11, and the shell 2 is in a state of being pressed. After one end of the discharge pipe rotates upward by a certain angle, the pressing plate 11 separates from the seesaw 6. Under the elastic force of the spring 9, the end of the seesaw 6 away from the pressing plate 11 rotates upward and resets. The seesaw 6 drives the first sphere 8 to rotate upward through the first connecting rod 7. After the first sphere 8 rotates upward by a certain angle, it collides with the bottom end of the shell 2. The vibration generated by the collision is transmitted to the shell 2. During the rotation of the shell 2 driven by the electric telescopic rod 4, the bentonite at both ends of the shell 2 moves toward the middle direction of the shell 2, which facilitates the stirring member 3 to stir and mix the bentonite at both ends. During the rotation of the shell 2, the two first spheres 8 continuously collide with the shell 2. Each collision generates vibration, which is transmitted to the bentonite.

[0030] The electric telescopic rod 4 drives the shell 2 to rotate back and forth, causing the shell 2 to tilt back and forth. During the reciprocating tilting process of the shell 2, the two first spheres 8 alternately hit the bottom end of the shell 2, and the vibration generated by the impact is transmitted to the bentonite in the shell 2. The vibration generated by the impact destroys the agglomeration between the bentonite particles and reduces the electrostatic adsorption between the particles, thereby effectively preventing the bentonite from agglomerating, making the bentonite evenly dispersed in the composite material, ensuring that the bentonite is in full contact with other materials, and the vibration causes the layered structure of the bentonite to be partially peeled off or rearranged to form a uniform composite bentonite, avoiding local performance differences. At the same time, the vibration accelerates the mixing process and reduces the mixing time.

[0031] Example 2: During the rotation of the pressure plate 11 driven by the spacing control member 10, the distance between the pressure plate 11 and the end of the seesaw 6 is constant. Each time the housing 2 rotates the set angle, the pressure plate 11 separates from the seesaw 6. The degree of squeezing the seesaw 6 is the same each time, resulting in the same collision intensity of the first sphere 8 on the housing 2. The collision intensity cannot be changed according to the amount of bentonite mixed, and thus the vibration intensity cannot be changed. Figure 4-6As another preferred embodiment of the present invention, the difference from Example 1 is that the spacing control member 10 includes a fixed plate 101, one end of the fixed plate 101 is fixedly connected to the bottom end of the shell 2, and a movable plate 102 is slidably inserted on the fixed plate 101, one end of the movable plate 102 is fixedly connected to the pressure plate 11, and a fixing screw 103 is fixedly connected to the pressure plate 11, one end of the fixing screw 103 passes through the fixed plate 101, and a first locking nut 104 is connected to the fixing screw 103, and a second locking nut 105 is connected to the fixing screw 103, and the fixed plate 101 is located between the first locking nut 104 and the second locking nut 105, and a mounting groove 106 is opened on one side of the movable plate 102, and a scale 107 is fixedly connected to the mounting groove 106.

[0032] Working principle:

[0033] When the vibration intensity needs to be changed, the first locking nut 104 and the second locking nut 105 are loosened, and the fixed screw 103 drives the pressure plate 11 to move in the horizontal direction, and the pressure plate 11 drives the movable plate 102 to move, and the movable plate 102 drives the scale 107 to move, and the scale 107 measures the movement distance of the movable plate 102, so as to determine the horizontal position of the pressure plate 11. After the position of the pressure plate 11 is determined, the first locking nut 104 and the second locking nut 105 are rotated so that the first locking nut 104 and the second locking nut 105 are in contact with the fixed plate 101. The first locking nut 104 and the second locking nut 105 fix the fixing screw 103, thereby fixing the pressure plate 11. The horizontal position of the pressure plate 11 can be changed as needed, thereby controlling the overlapping length between one end of the pressure plate 11 and the upper part of one end of the rocker 6;

[0034] When the overlapping length between one end of the pressure plate 11 and the upper part of one end of the seesaw 6 increases, the seesaw 6 needs to rotate a larger angle to separate from the pressure plate 11. The larger angle of rotation of the seesaw 6 will further squeeze the spring 9. When the elastic force of the spring 9 pushes the seesaw 6 to rotate and reset, the elastic potential energy released by the spring 9 increases, thereby increasing the collision intensity of the first sphere 8 on the bottom of the shell 2, and then increasing the vibration intensity. The collision intensity of the first sphere 8 on the shell 2 can be adjusted according to the required bentonite mixing amount.

[0035] Example 3: The fixing screw 103 drives the pressure plate 11 to move in the horizontal direction. The position of the pressure plate 11 in the horizontal direction can be changed as needed. After increasing the collision of the first sphere 8 with the bottom of the shell 2, it is easy to cause the shell 2 to deform or dent at the collision, and even cause cracks at the collision of the shell 2. Figure 6-8As another preferred embodiment of the present invention, the difference from Example 2 is that two parallel extension mechanisms 12 for preventing depression are connected to the shell 2, and the extension mechanism 12 includes a reinforcement ring 121, which is welded to the shell 2. The bottom end of the reinforcement ring 121 is fixedly connected to two sides of a second connecting rod 122, and the second connecting rod 122 is arranged parallel to the fixed plate 101. An arc plate 124 is slidably connected between the two second connecting rods 122, and one end of each second connecting rod 122 is fixedly connected to a limiting block 123, and each limiting block 123 is in contact with the lower surface of the arc plate 124. The upper end of the arc plate 124 is connected with several third connecting rods 125 at equal intervals along the arc direction, and one end of each third connecting rod 125 is fixedly connected with a second sphere 126, and the upper end of each second sphere 126 is in contact with the bottom end of the reinforcement ring 121. The radius of the second sphere 126 is smaller than the radius of the first sphere 8, and the upper end of each second sphere 126 is provided with an arc surface, and each arc surface cooperates with the bottom end of the reinforcement ring 121. The bottom end of the arc plate 124 is fixedly connected with a reinforcement block 127, and the reinforcement block 127 and the arc plate 124 are an integral structure, and the lower surface of the reinforcement block 127 is provided with an inclined surface.

[0036] Working principle:

[0037] The fixing screw 103 drives the pressing plate 11 to move in the horizontal direction. After increasing the overlap length between one end of the pressing plate 11 and the upper part of one end of the rocker plate 6, the rocker plate 6 needs to rotate a larger angle to separate from the pressing plate 11. The two second connecting rods 122 guide the curved plate 124, and the two limit blocks 123 support and limit the curved plate 124.

[0038] When the rocker plate 6 is rotated and reset under the elastic force of the spring 9, the first sphere 8 hits the reinforcement block 127. Since the lower surface of the reinforcement block 127 is an inclined surface, the impact effect on the reinforcement block 127 is improved. After the reinforcement block 127 is hit, an upward thrust is generated, and the reinforcement block 127 drives the arc plate 124 to move upward. Under the guidance of the two second connecting rods 122, the arc plate 124 contacts the bottom end of the reinforcement ring 121 through a plurality of second spheres 126. The reinforcement ring 121 protects the impact point of the shell 2 to prevent the shell from being damaged. The body 2 is dented at the impact point, and the multiple second spheres 126 increase the contact area with the reinforcement ring 121, dispersing the impact force to a larger area, reducing the force per unit area, thereby reducing local wear and extending the service life of the shell 2. At the same time, increasing the impact surface can avoid stress concentration and reduce the risk of damage to the shell 2 due to excessive local stress. In addition, increasing the impact surface can make the vibration more evenly transmitted to the bentonite, improving the mixing effect. A larger impact surface helps to cover more mixing areas and reduce mixing dead corners.

[0039] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
