Description

Technical Field

[0001] The present invention relates to the technical field of building materials, and particularly relates to a production process and a forming device for sheet mortar. Background Art

[0002] Traditional mortar has two forms: dry-mixed mortar and wet-mixed mortar, and the product states are presented as dry powder state and wet slurry state respectively. During the transportation of dry-mixed mortar, common problems such as component segregation and significant decrease in uniformity are likely to occur; the transportation cost of wet-mixed mortar is relatively high, and a special mixer truck is required to transport it to the construction site within a specified time.

[0003] There is a kind of sheet mortar in the prior art. When the sheet mortar is not in use, it presents a fixed sheet form, which is beneficial for transportation. When in use, only by spraying liquid on the sheet mortar can it be quickly dissolved into a wet slurry.

[0004] In the related art, the sheet mortar is usually produced by an extrusion molding method, that is, after mixing dry powder materials with an organic solvent to form a slurry, the slurry is then extruded to form sheet mortar; however, it is seriously affected by the rheological properties (fluidity, consistency, viscosity) of the slurry itself. Slight changes in the state of the slurry will make it impossible to extrude and form smoothly. If the consistency is too large, it is easy to block the forming die; if the consistency is too small, the slurry is prone to layering segregation (solid-liquid two-phase separation, and the organic solvent floats on the surface). Even slight changes in the type of raw materials, the composition ratio of raw materials, or even the origin of raw materials will cause significant changes in the rheological properties of the slurry, resulting in poor production smoothness of sheet mortar and poor product stability. Summary of the Invention

[0005] The present invention discloses a production process and a forming device for sheet mortar to solve the technical problems of poor production smoothness and poor product stability in the production process of sheet mortar in the related art.

[0006] To solve the above problems, the present invention adopts the following technical solutions:

[0007] In a first aspect, the present application provides a production process for sheet mortar, including the following steps:

[0008] Laying dry powder materials on a support in a preset shape to form a dry powder material layer;

[0009] Infiltrating the dry powder material layer with an organic solvent to form a mortar body;

[0010] Removing the organic solvent from the mortar body and curing the mortar body.

[0011] Furthermore, the production process of the flaky mortar also includes the following steps: compacting the dry powder layer before impregnating the dry powder layer with an organic solvent to form a mortar body; or, compacting the mortar body after impregnating the dry powder layer with an organic solvent and before removing the organic solvent from the mortar body.

[0012] Furthermore, the production process of the flaky mortar further includes the following steps: after the dry powder layer is infiltrated with an organic solvent to form a mortar body, a tie body is provided on the upper surface of the mortar body.

[0013] Furthermore, the preset shape includes at least one of a surface shape, a strip shape, and a point shape.

[0014] In a second aspect, the present application provides a flaky mortar forming device, which is applied to the aforementioned flaky mortar production process, and the forming device includes a silo and a combing scraper; wherein:

[0015] At least one of the silo and the support body can move along the extension direction of the support body, and the silo is used to lay the dry powder on the support body;

[0016] At least one of the combing scraper and the support body can move along the extension direction of the support body, and the combing scraper is used to form a dry powder layer of a preset shape. The dry powder layer can receive an organic solvent to form a mortar body, and the mortar body can be cured on the support body to form a sheet mortar.

[0017] Furthermore, a guide plate is provided in the silo, and the guide plate is obliquely arranged in the silo, and the bottom end of the guide plate is adjacent to the discharge port of the silo.

[0018] Furthermore, the combing scraper is detachably connected to the silo.

[0023] The production process and forming device of the sheet-shaped mortar of the present application lay dry powder materials on a support in a preset shape, and then soak the dry powder material layer with an organic solvent to bond the dry powder materials together to form a mortar body. After removing the organic solvent in the mortar body, the mortar body is cured, and the cured mortar body and the support form a sheet-shaped mortar. The method of forming a mortar body by first forming on a support and then soaking with an organic solvent is adopted. Compared with the traditional method of mixing dry powder materials and an organic solvent to form a wet mortar and then extruding and forming, it has the characteristics of simple production process, good production smoothness and good product stability, which is beneficial to improving the production rate and product quality of the sheet-shaped mortar.

[0039] In order to ensure the smoothness of the production of flaky mortar and the stability of product quality, the embodiments of the present application provide a production process and a molding device for flaky mortar. The technical solutions provided by the embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0040] Example 1

[0041] See also Figure 1 , which is a schematic diagram of a process for producing a flaky mortar according to an exemplary embodiment of the present application, see Figure 9 , is a schematic diagram of the structure of an exemplary sheet mortar of the present application, the sheet mortar includes a support body 5100 and a mortar body 5200, the mortar body 5200 is arranged on the support body 5100, and the production process of the sheet mortar may include the following steps:

[0042] S110, laying the dry powder on the support 5100 according to a preset shape to form a dry powder layer.

[0043] Among them, the dry powder material may include hydraulic binders and aggregates, or may include hydraulic binders, aggregates and water-soluble binders. The components of hydraulic binders, aggregates and water-soluble binders are described as follows:

[0044] Hydraulic binders refer to materials that can cement granular materials (such as sand and stone) or massive materials (such as bricks and tiles) into a whole in construction projects. The most commonly used hydraulic binder is cement. The hydraulic binder of the present invention is preferably at least one of Portland cement, limestone Portland cement, steel slag Portland cement, magnesium slag Portland cement, phosphorus slag Portland cement, white Portland cement, colored Portland cement, calcium sulfoaluminate modified Portland cement, calcium sulfoaluminate cement, aluminate cement, ferroaluminate cement, fluoroaluminate cement, phosphate cement, magnesium oxychloride cement, alunite cement and alkali-activated cement; more preferably at least one of Portland cement, calcium sulfoaluminate cement, aluminate cement and ferroaluminate cement;

[0045] Aggregates (also known as "aggregates") are at least one of natural sand, manufactured sand, lightweight aggregates and recycled aggregates. Among them, natural sand includes river sand, mountain sand, lake sand and desalinated sea sand; Manufactured sand refers to artificial sand made from rocks, tailings and industrial solid wastes through sand-making equipment; Lightweight aggregates refer to lightweight materials with a bulk density not greater than 1200 kg / m 3 , such as pumice, volcanic cinder, coal cinder, zeolite, self-combusting gangue, ceramsite, expanded perlite, vitrified microspheres, etc.; Recycled aggregates refer to particles that meet the requirements of fine aggregates for mortar obtained from waste concrete and construction waste through processes such as crushing, cleaning and sorting;

[0046] Water-soluble binders refer to binders that can dissolve in liquid water, especially in water at 5°C to 40°C. After the sheet-like mortar encounters water, the network structure formed by the water-soluble binder is disintegrated, causing the sheet-like mortar to dissolve and form a wet slurry.

[0047] In this embodiment, the support 5100 may be a structural member made of a water-permeable material, such as ceramic fiber cloth or fiberglass cloth; alternatively, the support 5100 may be a mesh structural member, such as a fiberglass mesh, a plastic mesh or a metal mesh.

[0048] In the implementation of this application, the preset shape includes at least one of planar, strip-shaped and dot-shaped, that is to say, the mortar body 5200 may include at least one of a planar mortar body 5210, a strip-shaped mortar body 5220 and a dot-shaped mortar body. Exemplarily, please refer to Figure 9 , the mortar body 5200 includes a planar mortar body 5210 and a plurality of strip-shaped mortar bodies 5220, and the plurality of strip-shaped mortar bodies 5220 are distributed on the planar mortar body 5210.

[0049] S120, soak the dry powder layer with an organic solvent to form a mortar body 5200.

[0050] Among them, the organic solvent is used to dissolve the aforementioned water-soluble binder. The water-soluble binder dissolves in the organic solvent to form a network structure, which binds other components in the dry powder to form the mortar body 5200.

[0051] In this embodiment, the dry powder layer can be soaked by spraying. The spraying method can make the dry powder layer evenly soaked and avoid damaging the preset shape of the dry powder layer.

[0052] It should be understood that whether the organic solvent is pre-dissolved with the water-soluble binder depends on whether the dry powder includes the water-soluble binder: when the dry powder includes the water-soluble binder, the organic solvent is not pre-dissolved with the water-soluble binder; when the dry powder does not include the water-soluble binder, the organic solvent is pre-dissolved with the water-soluble binder.

[0053] S130, remove the organic solvent from the mortar body 5200 and cure the mortar body 5200.

[0054] Among them, the method of removing the organic solvent adopts atmospheric drying, negative pressure drying, vacuum drying, microwave drying, infrared drying or electromagnetic drying. The dried and formed mortar body 5200 and the support body 5100 together form a sheet-like mortar. The sheet-like mortar can dissolve the mortar body 5200 again when encountering water, so as to form a wet slurry with the same adhesive function as traditional mortar.

[0055] It should be noted that the "removal" referred to in this article can include either completely removing the organic solvent from the mortar body 5200 or partially removing the organic solvent from the mortar body 5200. If there is partial residue during the process of removing the organic solvent, it should also be within the protection scope of this application.

[0056] Adopting the technical solution of this embodiment, after laying the dry powder on the support body 5100 according to the preset shape, then soaking the dry powder layer with the organic solvent to bond the dry powder together to form the mortar body 5200. After removing the organic solvent from the mortar body 5200, the mortar body 5200 is cured. The cured mortar body 5200 and the support body 5100 form a sheet-like mortar. Compared with the traditional method of mixing dry powder and organic solvent to form a wet mortar and then extruding it into shape, it has the characteristics of simple production process, good production smoothness and good product stability, which is beneficial to improving the productivity and product quality of the sheet-like mortar.

[0088] Example 6

[0089] See also Figures 6 - 10 , a flaky mortar forming device provided as an exemplary embodiment of the present application, is applied to the aforementioned flaky mortar production process.

[0090] In the embodiment of the present application, the disclosed forming device includes a material bin 1000 and a combing scraper 2000. Among them:

[0091] At least one of the silo 1000 and the support body 5100 can move along the extension direction of the support body 5100. A feed port is provided at the top of the silo 1000, and a discharge port is provided at the bottom of the silo 1000. The discharge port is located above the support body 5100. The dry powder material is put into the silo 1000 through the feed port, and flows out through the discharge port and is laid on the support body 5100.

[0092] At least one of the combing scraper 2000 and the support body 5100 can move along the extension direction of the support body 5100. The combing scraper 2000 is used to form a dry powder layer of a preset shape. The dry powder layer can receive an organic solvent to form a mortar body 5200. The mortar body 5200 can be cured on the support body 5100 to form a sheet mortar.

[0093] In the examples of this application, please continue to refer to Figure 6 The silo 1000 and the combing scraper 2000 can be fixedly arranged, and the support body 5100 can be movably arranged along its extension direction. Specifically, the molding device also includes a conveying unit 4000, and the conveying unit 4000 is used to convey the support body 5100 to move along its extension direction. The conveying unit 4000 can be a belt conveyor, and the conveyor belt of the belt conveyor can play a good bearing role on the support body 5100.

[0094] In other embodiments of the present application, the support 5100 can be fixedly arranged, and the silo 1000 can move along the extension direction of the support 5100 to lay the dry powder material on the support 5100. The material combing scraper 2000 can also move along the extension direction of the support 5100 to preform the laid dry powder material layer into a preset shape.

[0095] It should be understood that in the embodiments of the present application, the material combing scraper 2000 and the silo 1000 can be of an integral structure, and the dry powder material layer can be preformed into a preset shape during the feeding process. The material combing scraper 2000 and the silo 1000 can also be of a split structure, and the material combing scraper 2000 can preform the dry powder material layer into a preset shape after the silo 1000 feeds the material. The present application does not make specific limitations on this.

[0096] In a further technical solution, a flow guiding plate 1100 is further arranged in the silo 1000. The flow guiding plate 1100 is inclined in the silo 1000, and the bottom end of the flow guiding plate 1100 is adjacent to the discharge port of the silo 1000. On the one hand, the flow guiding plate 1100 can play a role in carrying the dry powder material in the silo 1000, avoiding the dry powder material from accumulating on the support 5100, resulting in a large traveling resistance of the support 5100 and the potential risk of fracture. On the other hand, the flow guiding plate 1100 can play a role in guiding the dry powder material, avoiding the dry powder material from forming a blockage in the silo 1000.

[0097] In a further technical solution, when the material combing scraper 2000 and the silo 1000 are of an integral structure, the material combing scraper 2000 is detachably connected to the silo 1000. By replacing the material combing scraper 2000 with different forms, the preset shape of the dry powder material layer can be changed. For example, when the bottom of the material combing scraper 2000 is flat, the dry powder material layer can be in a planar structure. When the bottom of the material combing scraper 2000 is a toothed structure, the dry powder material layer can be in a strip structure or a form combining a strip structure and a planar structure. The embodiments of the present application do not limit the specific form of the material combing scraper 2000.

[0098] The material combing scraper 2000 can be detachably connected to the silo 1000 by means such as threaded connection, magnetic attraction connection, and clamping connection. The embodiments of the present application do not limit the detachable connection manner between the material combing scraper 2000 and the silo 1000.

[0099] In an optional implementation manner, a plurality of tooth portions 2100 are arranged at intervals at the bottom of the material combing scraper 2000, and a channel opening 2200 is formed between two adjacent tooth portions 2100. When the dry powder material passes through the material combing scraper 2000, the dry powder material flows out from the channel opening 2200 and forms a strip structure, that is, the aforementioned preset shape includes a strip structure. After being infiltrated with an organic solvent, the formed mortar body 5200 includes a strip-shaped mortar body 5220.

[0100] It should be understood that when a plurality of tooth portions 2100 are arranged at intervals at the bottom of the material combing scraper 2000, the generated dry powder layer can also include a planar structure and a strip structure at the same time. Specifically, when there is a certain gap between the tooth portion 2100 and the lower support body 5100, a planar structure can be generated when the dry powder passes through this gap. At this time, the aforementioned preset shape includes a planar structure and a strip structure, and the mortar body 5200 formed after infiltrating the organic solvent includes a planar mortar body 5210 and a plurality of strip mortar bodies 5220 distributed on the planar mortar body 5210. A groove is formed between two adjacent strip mortar bodies 5220. When spraying liquid, the planar mortar can correspondingly contact with water over a larger area, and at the same time, it is easier to keep water in the groove, increasing the water capacity of the planar mortar, and thus significantly improving the speed and uniformity of being wetted and dissolved by water.

[0101] The forming device of the planar mortar may further include a pressing die unit 3000. The pressing die unit 3000 is used to compact the dry powder layer to improve the density of the dry powder layer, so that the finally formed mortar body 5200 has better structural strength, better structural stability of the mortar body 5200, which is beneficial to the handling and transportation of the planar mortar and is not prone to collapse.

[0102] In an alternative embodiment, the pressing die unit 3000 may include a roll pressing assembly rotatably arranged on the conveying path of the support body 5100. The roll pressing assembly includes a roll shaft 3100 and a roll body 3200 arranged on the roll shaft 3100. The roll body 3200 is used to compact the dry powder layer.

[0103] In a further technical solution, a plurality of roll grooves 3210 are arranged at intervals along the axial direction on the outer surface of the roll body 3200. The distribution positions of the plurality of roll grooves 3210 correspond one by one to the distribution positions of the aforementioned channel openings 2200. The opening area of the roll grooves 3210 is smaller than the opening area of the channel openings 2200. In this way, the roll grooves 3210 can compact the strip structure preformed by the material combing scraper 2000.

[0104] In a further technical solution, the opening shape of the roll grooves 3210 is trapezoidal. On the one hand, during the compaction process, it is not easy for materials to accumulate at the corners of the roll grooves 3210, which can avoid the accumulated materials from affecting the compaction and forming of the dry powder. On the other hand, the cross-section of the compacted strip structure is trapezoidal with a narrow upper part and a wide lower part, and it is not easy to collapse.

[0105] The inventor found during the research process that if the linear speed of the roll body 3200 is greater than the conveying speed of the conveying unit 4000, the support body 5100 is likely to be torn and broken. If the linear speed of the roll body 3200 is less than the conveying speed of the conveying unit 4000, the support body 5100 is likely to arch and cause the dry powder to scatter.

[0106] Based on the above situation, in a further technical solution, the relative moving speed between the silo 1000 and the support 5100 is the same as the linear speed of the roller 3200, and the linear speed of the roller 3200 is the same as the conveying speed of the conveying unit 4000, which can avoid the situation that the support 5100 is torn and broken or the support 5100 arches.

[0107] In another alternative embodiment, the die pressing unit 3000 may further include a pressing block that is lifted and arranged on the conveying path of the conveying unit 4000. The pressing block is provided with a pressing groove corresponding to the channel opening 2200, and the opening area of the pressing groove is smaller than the opening area of the channel opening 2200.

[0108] It should be noted that in this article, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the element. In addition, it should be pointed out that the scope of the methods and devices in the embodiments of the present application is not limited to performing functions in the order shown or discussed, and may also include performing functions in a substantially simultaneous manner or in a reverse order according to the functions involved.
