Description

Technical Field

[0001] The invention relates to the technical field of building materials, and in particular to a salt brick based on negative ion release and a preparation device thereof. Background Art

[0002] Negative ion particles (also called negative oxygen ions), known as "air vitamins", can promote human metabolism, prevent influenza, and enhance the body's resistance to disease. They are the first element to support a livable environment. In the natural state, the polarity of air molecules is neutral, that is, they are not charged. However, under the action of cosmic rays, ultraviolet rays, trace element radiation, lightning, etc., the air is ionized. When free electrons combine with other neutral gas molecules, negatively charged air negative ions are formed.

[0003] People have discovered that a natural rock salt ore has a pyroelectric effect and can release negative oxygen ions after heating. Therefore, negative ion fibers, coatings and decorative materials developed based on natural products have quickly appeared on the market, but their large-scale promotion is limited due to their high prices. In addition, some artificial ozone ion generating equipment, such as generators that generate negative oxygen ions through the tip of the polar needle corona discharge method, will also produce ozone (the current national standard for ozone concentration is 0.05ppm, the international standard is 0.075ppm, and usually exceeding 0.03ppm will have a bad effect on the human body). Although the concentration of ozone produced is lower than the national standard, people are still worried that it will cause harm to health and limit its application. Therefore, it is urgent to prepare a salt brick that is highly stable, evenly heated, and can fully release negative ions after heating; However, the existing salt brick preparation technology, especially the mixing device for preparing raw materials, not only has a single stirring structure, but usually, in order to ensure uniform mixing of the raw materials, a small amount of mixing is carried out in stages, and the machine needs to be stopped to replenish the mixed raw materials. Not only is the production efficiency low, but the raw materials in the lower layer of the mixing equipment and the raw materials added subsequently cannot be thoroughly mixed, resulting in the subsequent formed salt bricks not being heated uniformly, affecting the effective release of negative ions, and may also cause local deformation of the salt bricks after heating. Summary of the invention

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely 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.

[0026] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. Example

[0027] A salt brick based on negative ion release includes a main material and auxiliary materials. By mass fraction, the main material includes 50 parts of raw salt that has been ground; the auxiliary materials include a thermal conductor with a particle diameter of 0.5 mm to 1 mm, a binder, a reinforcing agent and a pigment, and the raw salt is dry-mixed with the thermal conductor, the binder and the reinforcing agent. The reinforcing agent includes 25 parts of α-hemihydrate gypsum, 4 parts of polyester heat-resistant agent and 8 parts of bentonite.

[0028] In this embodiment, polyester heat-resistant agent is added to the reinforcing agent, which not only has a high-strength polymerization effect, but also has high temperature resistance to prevent the finished salt brick from deforming. α-semihydrate gypsum and bentonite are used as base materials, which have higher hardness and density, and their crystal structure is more stable, further enhancing the strength of the salt brick under wall construction.

[0029] Wherein, by mass fraction, the thermal conductor includes 35 parts of NaCl light salt powder.

[0030] In this embodiment, NaCl light salt powder is used as a thermal conductor. In addition to utilizing electrothermal excitation to release negative ions from salt bricks, salt bricks to which NaCl light salt powder is added can also release negative ions under the action of light.

[0031] Calculated by mass fraction, the binder includes 1 part of fibrous cellulose.

[0032] In this embodiment, fibrous cellulose is used to bind the mixed extruded salt bricks before forming the particles, and is used in combination with a reinforcing agent to better ensure the solid strength of the salt bricks and improve the stability of the salt bricks acting on the wall.

[0033] By mass fraction, the pigment is 3 parts, and preferably iron oxide pigment. When applying, spraying, brushing or rolling can be used, and the specific method should be selected according to the actual situation. When applying, the pigment needs to be evenly applied to the surface of the stone brick, and brush marks and missed brushing should be avoided.

[0034] It should be noted that the salt brick wall panels in this embodiment are not used to construct supports. In actual use, an electric heating film is provided on one side of the salt brick wall. The salt brick wall is heated by electric control to cause it to release negative ions when heated. Negative ions, known as "air vitamins", can effectively improve air quality.

[0035] The safe temperature for heating salt bricks is generally 400-500℃. The specific safe temperature may vary depending on the material, production process and purpose of the salt bricks. Therefore, when using salt bricks for heating, choose a temperature-controllable heating device.

[0036] In this embodiment, the electric heating film and the salt brick are used for bonding. When working, the carbon molecular crystals or conductive slurry at both ends of the electric heating film generate heat through friction and collision after power is turned on, and emit infrared light waves, so that the salt brick wall releases negative ions under heating conditions. Because heating helps to promote the deliquescence process inside the salt brick, it accelerates the generation of negative ions, so that the salt brick can be per cm 3 The air can be heated and cooled by 500-700 negative ions, effectively improving the quality of indoor air.

[0037] Exemplarily, the preparation steps of the above-mentioned salt brick based on negative ion release are as follows: Step 1: According to the wall stacking area and stacking structure, design the brick layout plan to determine the structural size of the salt bricks, prepare the corresponding mold and set it aside; Step 2: Throw the main material and auxiliary material into a mixing device according to the mass ratio and mix them thoroughly to obtain a mixed material; Step 3: Add the mixture into the press mold and use a room temperature stamping process to lock more negative ion base materials at room temperature; after staying under 95MPa pressure for 8-12s, take out the formed salt brick to improve the structural stability of the salt brick; finally, put it into an electric furnace for firing and annealing for 1h to obtain a salt brick based on negative ion release; Step 4: Spray pigment on the salt bricks after molding, place them in a ventilated and dry environment, and let them dry naturally or in an oven to ensure the hardness and stability of the salt bricks.

[0038] Exemplarily, the electric furnace firing and annealing process includes three stages: heating, heat preservation and cooling. In the heating stage, the molecules inside the crystal overcome the lattice resistance, the atoms relax and move, and the microstructure changes; in the heat preservation stage, the material is further optimized in a steady state, and the residual stress is released; in the cooling stage, rapid cooling is usually used to fix the shape to avoid new defects or structural changes. Annealing can reduce the hardness of the salt brick, improve its plasticity, facilitate cutting, grinding and other processing operations, and also facilitate subsequent installation and use. During the annealing process, the molecules inside the salt brick gradually overcome the resistance of the lattice, start the relaxation and movement of the atoms, change the microstructure of the salt brick, repair or eliminate the defects, improve the clarity of the grain boundaries, and refine the grains, thereby improving the mechanical properties of the salt brick. The annealing process improves the performance of the salt brick, improves its quality and performance stability, eliminates the residual stress inside the tile, and ensures the dimensional stability and service life of the tile.

[0039] The present invention also discloses a preparation device for preparing salt bricks based on negative ion release, please refer to Figure 1-Figure 5 , including a mixing drum 1, a stirring shaft 14 is rotatably installed in the mixing drum 1, a stirring blade 15 is fixedly installed on the surface of the stirring shaft 14, the top end of the stirring shaft 14 extends to the outside of the mixing drum 1 and is transmission-connected to a motor 11, a first synchronous pulley 24 is fixedly installed on the output shaft end of the motor 11, a second synchronous pulley 25 is fixedly installed on the top end of the stirring shaft 14, and the first synchronous pulley 24 and the second synchronous pulley 25 are transmission-connected via a transmission belt 26.

[0040] The motor 11 is started to drive the first synchronous pulley 24 and the transmission belt 26 connected between the first synchronous pulley 24 and the second synchronous pulley 25, so that the stirring shaft 14 is driven to rotate in the mixing drum 1 through the second synchronous pulley 25, and the brick-making particles in the mixing drum 1 are mixed by the stirring blades 15 at the bottom end of the stirring shaft 14.

[0041] It should be noted that Figure 2 As shown, a protective cover 2 is arranged outside the motor 11 and related mechanical structures.

[0042] The preparation device also includes: Two groups of symmetrically arranged material discharge components are floatingly arranged on the top of the mixing drum 1, and the material discharge components include a group of first material discharge hoppers 3 and two groups of symmetrically arranged second material discharge hoppers 6. A material discharge pipe 5 is arranged on the top of the mixing drum 1, and a material guide pipe 4 is arranged at the bottom of the second material discharge hopper 6. The material guide pipe 4 is slidably inserted in the material discharge pipe 5. The first material discharge hopper 3 and the material discharge pipe 5 are fixedly connected. An elastic connection component is arranged between the second material discharge hopper 6 and the top cover of the mixing drum 1. The elastic connection component includes springs 7 symmetrically arranged on both sides of the second material discharge hopper 6. The top end of the spring 7 is fixedly connected to the two sides of the opening of the second material discharge hopper 6, and the bottom end of the spring 7 is fixedly connected to the upper surface of the top cover of the mixing drum 1.

[0043] In this embodiment, a fixed first lower hopper 3 is provided to continuously input a relatively large proportion of main material particles, and the other two groups respectively add different auxiliary materials through the second lower hopper 6, so that the feeding component can evenly throw the raw materials into the mixing drum 1, and the second lower hopper 6 and the top cover of the mixing drum 1 are connected by a spring 7, and the auxiliary materials are added by the second lower hopper 6 that vibrates in the vertical direction. Under the premise of ensuring that the raw material dosage is sufficient, the auxiliary materials can be evenly fed without stopping the machine, thereby improving production efficiency.

[0044] Specifically, a vibration assembly for making the second lower hopper 6 float vertically is arranged between the second lower hopper 6 and the stirring shaft 14, and the vibration assembly includes two groups of first bevel gears 12 and a second bevel gear 13 fixedly connected to the top of the stirring shaft 14, the first bevel gear 12 and the second bevel gear 13 are meshed, and a driving rod 8 rotatably arranged on the top cover of the mixing barrel 1 is connected between the two groups of first bevel gears 12, and cams 9 are fixedly installed at both ends of the driving rod 8, and the cam 9 is rotatably fitted on the second lower hopper 6, and a limiting groove 10 matching the cam 9 is opened on the upper surface of the second lower hopper 6.

[0045] In this embodiment, the rotation of the stirring shaft 14 drives the second bevel gear 13 at the top of the spring 7 to rotate, and the second bevel gear 13 drives the first bevel gear 12 meshing with it. The rotation of the first bevel gear 12 drives the driving rods 8 on both sides to rotate, thereby driving the cam 9 to rotate in the limit groove 10 opened in the second lower hopper 6. During the rotation of the cam 9, the eccentric structure of the cam 9 is used to press down the second lower hopper 6. When the cam 9 rotates to the highest point at the top, the reset of the spring 7 causes the second lower hopper 6 to move up and reset, thereby realizing the displacement of the second lower hopper 6 in the vertical direction, thereby producing the effect of vibrating the material discharge, and effectively avoiding the blockage of the material discharge.

[0046] It should be noted that the above-mentioned material discharge component uses the stirring shaft 14 as a driving component, and through the bevel gear reversing transmission, combined with the cam and the elastically connected material discharge hopper, synchronous stirring and material discharge are achieved to ensure uniform mixing.

[0047] A material-diverting assembly is horizontally arranged inside the mixing drum 1 and can be flipped. The material-diverting assembly includes two sets of flaps 19 that are flippably connected to the inner wall of the mixing drum 1. A double-ear support 18 is fixedly connected to one side of the flap 19. A first connecting block 16 is connected to the inner wall of the mixing drum 1. The double-ear support 18 and the first connecting block 16 are pinned together by a first pin shaft 17. A second connecting block 22 is fixedly connected to the side of the flap 19 close to the stirring shaft 14. The second connecting block 22 is pinned to a traction block 21 through a second pin shaft 23. A traction rope 20 is wound around the surface of the driving rod 8. The traction rope 20 is fixedly connected to the traction block 21 at one end away from the driving rod 8.

[0048] In this embodiment, two groups of flaps 19 with stirring directions different from those of the stirring shaft 14 are horizontally arranged in the mixing drum 1. At the same time, the rotation of the driving rod 8 is used as a traction force to drive the flaps 19 to mix the main materials and auxiliary materials for preparing salt bricks in the mixing drum 1. This not only improves the mixing effect, but also the two groups of flaps 19 are linked through the driving rod 8, which reduces the use of electrical equipment, saves equipment preparation costs, ensures uniform distribution of raw materials during subsequent extrusion molding of salt bricks, ensures effective release of negative ions after heating, and avoids deformation of the finished salt bricks during use.

[0049] During use of the device of the present invention, the main material storage tank is first connected to the first discharge hopper 3, and the auxiliary material storage tank is respectively connected to the two groups of second discharge hoppers 6. It should be noted that the auxiliary material is premixed before entering the auxiliary material storage tank, and the main material and auxiliary material are discharged into the mixing barrel 1 at the same time.

[0050] The motor 11 is started to drive the first synchronous pulley 24 and the transmission belt 26 connected between the first synchronous pulley 24 and the second synchronous pulley 25, so that the stirring shaft 14 is driven to rotate in the mixing drum 1 through the second synchronous pulley 25, and the brick-making particles in the mixing drum 1 are mixed by the stirring blades 15 at the bottom end of the stirring shaft 14.

[0051] The rotation of the stirring shaft 14 drives the second bevel gear 13 at the top of the spring 7 to rotate, and the second bevel gear 13 drives the first bevel gear 12 meshing with it. The rotation of the first bevel gear 12 drives the driving rods 8 on both sides to rotate, thereby driving the cam 9 to rotate in the limit groove 10 opened in the second lower hopper 6. During the rotation of the cam 9, the eccentric structure is used to press down the second lower hopper 6. When the cam 9 rotates to the highest point at the top, the reset of the spring 7 causes the second lower hopper 6 to move up and reset, thereby realizing the displacement of the second lower hopper 6 in the vertical direction, thereby producing the effect of vibrating the material discharge, and effectively avoiding the blockage of the material discharge.

[0052] The rotation of the driving rod 8 reels up the traction rope 20, and the traction rope 20 pulls the flap 19 to flip to a certain angle. The positive and negative alternating rotation of the driving rod 8 is controlled by the positive and negative alternating rotation of the stirring shaft 14, driving the flap 19 to mix and stir the raw material particles in the middle horizontal layer of the mixing drum 1, thereby effectively improving the mixing efficiency and effect of the entire mixing drum 1.
