Description

Technical Field

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

[0002] Composite bentonite is a composite material formed by mixing bentonite with other materials (such as polymers, fibers, minerals, etc.). Bentonite itself is a natural clay mineral mainly composed of montmorillonite, and has excellent water absorption, swelling property, adsorption property and ion exchange capacity.

[0003] In the production process of composite bentonite, the composite bentonite material is introduced into a mixing device for mixing processing. The composite bentonite is mixed by the cooperation of a stirring member and a housing. When mixing, the housing is generally in a fixed state. When the composite bentonite is introduced into the interior of the housing, when the housing is vertically arranged, the mixing effect of the composite bentonite at the bottom corners is poor. When the housing is horizontally arranged, the mixing effect of the composite bentonite at the two end corners of the housing is poor. When the housing is inclined, the mixing effect of the composite bentonite at the low-end corners of the housing is poor. Since the position of the stirring member and the composite bentonite in the housing is relatively fixed, the mixing effect of the composite bentonite at the end corners of the housing is poor. At the same time, because bentonite has strong adsorption property, and during the stirring process, friction occurs between the composite bentonite and the housing, and static electricity is generated by the friction between bentonite particles, resulting in the agglomeration of bentonite and reducing the mixing effect of bentonite. Summary of the Invention

[0004] The purpose of the present invention is to solve the disadvantages in the prior art that the position of the stirring member and the composite bentonite in the housing is relatively fixed, resulting in poor mixing effect of the composite bentonite at the end corners of the housing, and at the same time, the bentonite particles are prone to agglomerate during the stirring process, and to propose a composite bentonite mixing device.

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

[0006] Design a composite bentonite mixing device, including a chassis. The upper end of the chassis is rotatably connected with a housing. An electric telescopic rod for driving the housing to rotate is rotatably connected to the chassis. A strip-shaped hole is opened on the chassis. A rocker is rotatably connected to the strip-shaped hole through a connecting shaft. A spring is fixedly connected to the lower surface of the rocker. One end of the spring is fixedly connected to the chassis. First connecting rods are fixedly connected to both sides of the upper end of the rocker. A first sphere is fixedly connected to the upper end of each first connecting rod. A spacing control member is fixedly connected to the bottom end of the housing. A pressing plate is fixedly connected to the spacing control member. One end of the pressing plate is in contact with the upper part of one end of the rocker.

[0007] Preferably, both ends of the rocker are of arc-shaped structures.

[0008] Preferably, the spacing control member includes a fixed plate, one end of the fixed plate is fixedly connected to the bottom end of the housing, a movable plate is slidably inserted into the fixed plate, one end of the movable plate is fixedly connected to the pressing plate, a fixed screw is fixedly connected to the pressing plate, one end of the fixed screw passes through the fixed plate, a first locking nut is connected to the fixed screw, a second locking nut is connected to the fixed screw, and the fixed plate is located between the first locking nut and the second locking nut.

[0009] Preferably, an installation groove is formed on one side of the movable plate, and a scale is fixedly connected to the installation groove.

[0010] Preferably, two parallel extension mechanisms for preventing depression are connected to the housing. The extension mechanism includes a reinforcement ring, the reinforcement ring is welded to the housing, second connecting rods are fixedly connected to both sides of the bottom end of the reinforcement ring, the second connecting rods are arranged parallel to the fixed plate, an arc-shaped plate is slidably connected between the two second connecting rods, a limiting block is fixedly connected to one end of each second connecting rod, each limiting block is in contact with the lower surface of the arc-shaped plate, a plurality of third connecting rods are connected to the upper end of the arc-shaped plate at equal intervals along the arc direction, a second sphere is fixedly connected to one end of each third connecting rod, and the upper end of each second sphere is in contact with the bottom end of the reinforcement ring.

[0011] Preferably, the radius of the second sphere is smaller than the radius of the first sphere, an arc surface is formed on the upper end of each second sphere, and each arc surface is matched with the bottom end of the reinforcement ring.

[0012] Preferably, a reinforcement block is fixedly connected to the bottom end of the arc-shaped plate, the reinforcement block and the arc-shaped plate are of an integral structure, and an inclined surface is formed on the lower surface of the reinforcement block.

[0013] The beneficial effects of a composite bentonite mixing device proposed by the present invention are as follows:

[0014] During the reciprocating tilting process of the housing, the bentonite inside moves reciprocally along the length direction of the housing, so that the bentonite at the end flows towards the middle area of the housing, and the relative position between the bentonite in the housing and the stirring member changes, improving the mixing effect of the bentonite at the end corners. At the same time, during the reciprocating tilting process of the housing, the two first spheres alternately impact the bottom end of the housing, and the vibration generated by the impact is transmitted to the bentonite in the housing. The vibration generated by the impact destroys the agglomeration between bentonite particles and reduces the electrostatic adsorption between particles, thereby effectively preventing the agglomeration of bentonite.

Detailed implementation method

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0025] Example 1: Refer to Figures 1-3, A composite bentonite mixing device, including a chassis 1. The upper end of the chassis 1 is rotatably connected to a housing 2. One side of the upper end of the housing 2 is communicated with a feed pipe, and one end of the housing 2 is communicated with a discharge pipe. A stirring member 3 for mixing materials is connected to the housing 2. An electric telescopic rod 4 for driving the housing 2 to rotate is rotatably connected to the chassis 1. A strip-shaped hole 5 is opened on the chassis 1. A seesaw 6 is rotatably connected to the strip-shaped hole 5 through a connecting shaft. Both ends of the seesaw 6 are arc-shaped structures. A spring 9 is fixedly connected to the lower surface of the seesaw 6. One end of the spring 9 is fixedly connected to the chassis 1. Both sides of the upper end of the seesaw 6 are fixedly connected with a first connecting rod 7. A first sphere 8 is fixedly connected to the upper end of each first connecting rod 7. A spacing control member 10 is fixedly connected to the bottom end of the housing 2. A pressing plate 11 is fixedly connected to the spacing control member 10. One end of the pressing plate 11 is in contact with the upper part of one end of the seesaw 6.

[0026] Working principle:

[0027] Pour the bentonite to be mixed into the housing 2 through the feed pipe. After the stirring member 3 is started, it stirs the bentonite in the housing 2. At the same time, after the electric telescopic rod 4 is started, it drives the housing 2 to swing back and forth, making the housing 2 tilt back and forth. During the reciprocating tilting of the housing 2, the internal bentonite moves back and forth along the length direction of the housing 2, causing the bentonite at the end to flow towards the middle area of the housing 2, changing the position of the bentonite at the end corner, and changing the relative position between the bentonite in the housing 2 and the stirring member 3. During the rotation of the stirring member 3, it mixes the moving bentonite, improving the mixing effect of the bentonite at the end corner;

[0028] When the telescopic end of the electric telescopic rod 4 pushes one end of the housing 2 to rotate upward, the end of the housing 2 where the discharge pipe is located rotates downward. The housing 2 drives the spacing control member 10 to rotate downward, and the spacing control member 10 drives the pressing plate 11 to rotate downward. During the downward rotation of the pressing plate 11, it squeezes one end of the seesaw 6. The pressed end of the seesaw 6 rotates downward around the connecting shaft. After the pressed end of the seesaw 6 rotates downward, it squeezes the spring 9. After the spring 9 is compressed, it generates an elastic force. After the pressed end of the seesaw 6 rotates downward, it drives the first sphere 8 to rotate through the first connecting rod 7. As the end of the housing 2 where the discharge pipe is located continues to rotate downward, the pressing plate 11 continuously squeezes the seesaw 6. After the end of the housing 2 where the discharge pipe is located rotates downward by a certain angle, the pressing plate 11 separates from the seesaw 6. Under the elastic force of the spring 9, it pushes the seesaw 6 to rotate upward and reset. 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 housing 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 housing 2 to rotate downward, the end of the housing 2 located at the discharge pipe rotates upward. The housing 2 drives the spacing control member 10 to rotate upward, and the spacing control member 10 drives the pressing plate 11 to rotate upward. During the upward rotation of the pressing plate 11, the pressing plate 11 gradually presses the rocker 6. One end of the rocker 6 being pressed rotates upward around the connecting shaft. After one end of the rocker 6 being pressed rotates upward, the tension spring 9 is stretched. After the spring 9 is pulled, it generates an elastic force. The end of the rocker 6 away from the pressing plate 11 rotates downward. The end of the rocker 6 away from the pressing plate 11 drives the first sphere 8 to rotate downward through another first connecting rod 7. As the end of the housing 2 located at the discharge pipe continues to rotate upward, by continuously pressing the rocker 6 with the pressing plate 11, after the end of the housing 2 located at the discharge pipe rotates upward by a certain angle, the pressing plate 11 separates from the rocker 6. Under the elastic force of the spring 9, the end of the rocker 6 away from the pressing plate 11 rotates upward to reset. The rocker 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 housing 2. The vibration generated by the collision is transmitted to the housing 2. During the process of the electric telescopic rod 4 driving the housing 2 to rotate, the bentonite at both ends of the housing 2 moves toward the middle direction of the housing 2, which is convenient for the stirring member 3 to stir and mix the bentonite at both ends. During the rotation of the housing 2, the two first spheres 8 continuously collide with the housing 2, and each collision generates vibration, and the generated vibration is transmitted to the bentonite;

[0030] The electric telescopic rod 4 drives the housing 2 to rotate reciprocally, causing the housing 2 to tilt reciprocally. During the reciprocal tilting of the housing 2, the two first spheres 8 alternately impact the bottom end of the housing 2. The vibration generated by the impact is transmitted to the bentonite in the housing 2. The vibration generated by the impact destroys the agglomeration between bentonite particles and reduces the electrostatic adsorption between particles, thereby effectively preventing the bentonite from caking, making the bentonite evenly dispersed in the composite material, ensuring full contact between the bentonite and other materials. The vibration causes partial peeling or rearrangement of the layered structure of the bentonite, forming 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 process of the spacing control member 10 driving the pressing plate 11 to rotate, the distance between the pressing plate 11 and the end of the rocker 6 is constant. Each time the housing 2 rotates by a set angle, the pressing plate 11 separates from the rocker 6. The degree of extrusion of the rocker 6 is the same each time, resulting in the same collision intensity of the first sphere 8 against the housing 2, and the vibration intensity cannot be changed according to the mixing amount of the bentonite, so the vibration intensity cannot be changed. Refer to Figures 4-6, as another preferred embodiment of the present invention, the difference from Embodiment 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 housing 2. A movable plate 102 is slidably inserted into the fixed plate 101. One end of the movable plate 102 is fixedly connected to a pressure plate 11. A fixed screw 103 is fixedly connected to the pressure plate 11. One end of the fixed screw 103 passes through the fixed plate 101. A first locking nut 104 is connected to the fixed screw 103. A second locking nut 105 is connected to the fixed screw 103. The fixed plate 101 is located between the first locking nut 104 and the second locking nut 105. An installation groove 106 is formed on one side of the movable plate 102. A scale 107 is fixedly connected to the installation groove 106.

[0032] Working principle:

[0033] When it is necessary to change the vibration intensity, loosen the first locking nut 104 and the second locking nut 105. The fixed screw 103 drives the pressure plate 11 to move in the horizontal direction. The pressure plate 11 drives the movable plate 102 to move. The movable plate 102 drives the scale 107 to move. The scale 107 measures the moving distance of the movable plate 102, which is convenient for determining the position of the pressure plate 11 in the horizontal direction. After the position of the pressure plate 11 is determined, rotate the first locking nut 104 and the second locking nut 105 so that both 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 fixed screw 103, thereby fixing the pressure plate 11. The position of the pressure plate 11 in the horizontal direction can be changed as needed, so as to control 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 rocker 6 increases, the rocker 6 needs to rotate a larger angle to separate from the pressure plate 11. The rocker 6 rotating a larger angle will further compress the spring 9. When the spring 9 rebounds under the elastic force to drive the rocker 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 against the bottom of the housing 2, and further increasing the vibration intensity. The collision intensity of the first sphere 8 against the housing 2 can be adjusted according to the requirement of the bentonite mixing amount.

[0035] Embodiment 3: The fixed 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 against the bottom of the housing 2, it is easy to cause deformation or depression at the collision part of the housing 2, and even cracks may occur at the collision part of the housing 2. Refer to Figures 6-8, as another preferred embodiment of the present invention, the difference from Embodiment 2 is that two parallel extension mechanisms 12 for preventing dents are connected to the housing 2. The extension mechanism 12 includes a reinforcement ring 121, the reinforcement ring 121 is welded to the housing 2, and both sides of the bottom end of the reinforcement ring 121 are fixedly connected with second connecting rods 122. The second connecting rods 122 are arranged in parallel with the fixing plate 101. An arc-shaped plate 124 is slidably connected between the two second connecting rods 122. One end of each second connecting rod 122 is fixedly connected with a limiting block 123, and each limiting block 123 is in contact with the lower surface of the arc-shaped plate 124. A plurality of third connecting rods 125 are connected to the upper end of the arc-shaped plate 124 at equal intervals along the arc direction. One end of each third connecting rod 125 is fixedly connected with a second sphere 126. 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. An arc surface is provided at the upper end of each second sphere 126, and each arc surface is matched with the bottom end of the reinforcement ring 121. The bottom end of the arc-shaped plate 124 is fixedly connected with a reinforcement block 127. The reinforcement block 127 and the arc-shaped plate 124 are of an integral structure, and an inclined surface is provided on the lower surface of the reinforcement block 127.

[0036] Working principle:

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

[0038] When the rocker 6 is driven by the elastic force of the spring 9 to rotate and reset, the first sphere 8 impacts 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 being impacted, the reinforcement block 127 generates an upward thrust. The reinforcement block 127 drives the arc-shaped plate 124 to move upward. Under the guidance of the two second connecting rods 122, the arc-shaped 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 part of the housing 2 to prevent the impact part of the housing 2 from being dented. Moreover, the plurality of second spheres 126 increase the contact area with the reinforcement ring 121, disperse the impact force over a larger area, reduce the force per unit area, thereby reducing local wear and extending the service life of the housing 2. At the same time, increasing the impact surface can avoid stress concentration, reduce the risk of damage to the housing 2 due to excessive local stress, and 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 are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
