Description

Technical Field

[0001] This application relates to the field of mortar production equipment, and in particular to a dry powder mortar production equipment and its production process. Background Technology

[0002] This application relates to the field of building material production equipment technology, and in particular to dry mortar production equipment. Dry mortar is mainly made by mixing cement, sand, and additives in a set ratio. It is a core supporting material for modern building construction, and has the application value of convenient construction, stable performance, and environmental protection and high efficiency. The industry mainstream adopts automated and continuous production lines to achieve large-scale production. Raw materials and finished products are generally stored in closed silos and transferred in closed spiral conveyors to ensure continuous production and a clean and stable supply of raw materials.

[0003] In existing technologies, dry mortar production equipment encompasses a complete process including raw material storage, precise metering, closed conveying, forced mixing, and packaging. The equipment as a whole consists of a multi-compartment storage system, a high-precision metering system, a horizontal mixing host, a closed conveying system, and an automated electrical control system. The mixing host, as the core working component, typically employs a horizontal single-shaft or dual-shaft forced mixing structure. After the raw materials are conveyed to the mixing host via closed conveying equipment such as screw conveyors or bucket conveyors, the mixing blades are rotated by the mixing shaft, achieving uniform mixing of multiple components such as cement, sand, and additives. Existing technologies are designed with the core logic of improving continuous production efficiency and ensuring mixing quality and batch stability, effectively meeting the large-scale, standardized production needs of the construction industry.

[0004] Regarding the aforementioned technologies, the mixing shaft and its blades of the mixing host are prone to adhering to dry mortar material during operation. The residual material easily dries and clumps, which not only contaminates subsequent production batches and reduces product quality stability, but also leads to time-consuming and labor-intensive cleaning operations, significantly reducing equipment turnover efficiency. This restricts the adaptability and application of dry mortar mixing equipment in production scenarios involving multiple product types, small batches, and frequent material changes. Summary of the Invention

[0005] In order to make dry mortar production equipment easier to clean and adapt to production scenarios with multiple categories, small batches, and frequent material changes, this application provides a dry mortar production equipment.

[0006] The dry mortar production equipment provided in this application adopts the following technical solution: A dry mortar production equipment includes a raw material conveyor, a mixing host, and a storage silo. The raw material conveyor is used to transport the dry mortar raw materials to be mixed to the mixing host, and the storage silo is used to receive the dry mortar after it has been mixed by the mixing host. The mixing host includes a host base, a mixing chamber, a mixing chamber door, and a mixing main shaft. The mixing chamber is installed on the host base, and a mixing compartment is opened inside the mixing chamber. The mixing chamber door is used to open and close the side of the mixing compartment. The host base is horizontally slidably fitted with a first base and a second base, and the second base is rotatably fitted with a third base. The mixing main shaft is arranged along the width direction of the mixing chamber, and the two ends of the mixing main shaft are rotatably fitted with the first base and the third base, respectively. There is an angle between the rotation axis of the second base and the rotation axis of the mixing main shaft. The mixing main shaft is equipped with mixing blades.

[0007] By adopting the above technical solution, the raw material conveyor can stably transport the dry mortar raw materials to be mixed to the mixing host, and the storage silo can stably receive the dry mortar after mixing by the mixing host, ensuring a continuous and smooth dry mortar production process. The mixing chamber door can be opened and closed from the side, providing operating space for the mixing spindle to move out of the mixing chamber. The host base and the first base slide horizontally together, and the second base and the third base rotate together, which can drive the mixing spindle out of the mixing chamber and adjust its placement angle. After the mixing spindle and mixing blades are moved outside the mixing chamber, cleaning operations are facilitated, reducing the residue of dry mortar materials on the mixing spindle and mixing blades. This helps to prevent residual materials from drying and clumping, thereby reducing the impact of residual materials on the quality of subsequent production batches, thus improving the turnover efficiency of the dry mortar production equipment. This allows the dry mortar production equipment to adapt to production scenarios with multiple categories, small batches, and frequent material changes, broadening the scope of application of the equipment.

[0008] Optionally, the mixing chamber door is rotatably fitted to the bottom of the mixing chamber body, the mixing chamber door is rotatably fitted with a door locking rod, the door locking rod is fitted with a locking handwheel, and the locking handwheel is threadedly fitted to the top of the mixing chamber body.

[0009] By adopting the above technical solution, the mixing chamber door can rotate and open around the bottom of the mixing chamber body, facilitating safe and quick opening of the mixing chamber to remove the mixing main shaft and mixing blades, thus reducing losses caused by door failure. The door locking lever limits the closed state of the mixing chamber door. The locking handwheel is threaded into the mixing chamber body, allowing the locking lever to be locked and released by rotating the handwheel, thereby stabilizing the closed position of the mixing chamber door and preventing accidental opening during production. Simultaneously, the threaded locking handwheel is easy to operate, improving the convenience of opening, closing, and locking the mixing chamber door, thereby ensuring the sealing stability of the mixing main unit during production and reducing leakage of dry mortar materials.

[0010] Optionally, the inner wall of the mixing chamber is provided with sealing ribs, and when the mixing chamber door is closed, the sealing ribs fit against the inner side of the mixing chamber door.

[0011] By adopting the above technical solution, sealing ribs are provided on the inner wall of the mixing chamber. When the mixing chamber door is closed, the sealing ribs can fit against the inner side of the mixing chamber door, thereby improving the sealing effect between the mixing chamber door and the mixing chamber. This helps reduce the leakage of dry mortar materials from the mixing chamber through the gaps, thus ensuring the airtightness of the mixing host during operation and reducing material loss and dust pollution at the production site. At the same time, the sealing ribs can enhance the structural strength of the side walls of the mixing chamber, which helps improve the overall structural stability of the mixing chamber and extend the service life of the mixing host.

[0012] Optionally, the side of the mixing chamber is provided with a main shaft clearance groove, which is adapted to the mixing main shaft. The main base is rotatably fitted with a power gear, which has a power input. The mixing main shaft is equipped with a main shaft gear, which meshes with the power gear.

[0013] By adopting the above technical solution, the main shaft clearance groove opened on the side of the mixing chamber is adapted to the mixing main shaft, providing clearance space for the removal and repositioning of the mixing main shaft, facilitating the smooth entry and exit of the mixing main shaft into and out of the mixing chamber. The drive gear rotates and engages with the main unit base and has power input, enabling stable transmission of rotational power. The main shaft gear is installed on the mixing main shaft and meshes with the drive gear, smoothly transmitting the power of the drive gear to the mixing main shaft, thereby driving the mixing main shaft to rotate stably. This helps ensure the stability of power transmission of the mixing main shaft, thereby improving the mixing effect of the mixing main unit. At the same time, when sliding and pushing the mixing main shaft, interference between the drive gear and the main shaft gear is not likely to occur, making it easy to pull out or push in directly, which helps reduce the interference of disassembly and assembly of the power input system during cleaning and maintenance.

[0014] Optionally, the mixing chamber is provided with a chamber partition, which divides the mixing chamber into several sub-chambers distributed along the width of the mixing chamber for independent mixing. The chamber partition is detachably installed on the mixing chamber body and is disassembled when the mixing chamber door is opened.

[0015] By adopting the above technical solution, the compartment partition can divide the mixing chamber into several sub-compartments distributed along the width of the mixing chamber, enabling the mixing host to simultaneously carry out multiple independent dry mortar mixing operations. The compartment partition is detachably installed in the mixing chamber body and can be disassembled when the mixing chamber door is opened, facilitating flexible adjustment of the number and partition specifications of the sub-compartments according to production needs, thereby adapting to the production requirements of different formulations and batches of dry mortar. Independently separated sub-compartments reduce cross-interference between materials of different formulations, helping to avoid material mixing affecting product quality, thus improving the quality stability of multi-category dry mortar production. At the same time, the compartment partition is easy to disassemble and assemble, improving the efficiency of internal structural adjustments within the mixing chamber and broadening the production adaptability range of the dry mortar production equipment.

[0016] Optionally, the mixing spindle is provided in two sets, the two sets of mixing spindles are arranged side by side, and each of the two sets of mixing spindles is provided with a set of compartment partitions. The two sets of compartment partitions are assembled by tongue and groove, and the mixing compartment is separated by the two sets of compartment partitions after assembly.

[0017] By adopting the above technical solution, the two sets of parallel mixing spindles can simultaneously perform dry mortar mixing operations, improving the mixing efficiency and uniformity of the mixing host. The two sets of compartment partitions are assembled using tongue and groove joints, which improves the airtightness and connection stability of the compartment partition joints, thereby stably completing the separation of the mixing compartments. This helps to prevent material cross-contamination between the separated sub-compartments, thus ensuring the quality stability of multiple independent mixing operations.

[0018] Optionally, the mixing chamber has a chamber positioning groove, the mixing chamber door is rotatably fitted to the mixing chamber, the mixing chamber door has a door positioning groove, and when the mixing chamber door is closed, the top and side of the chamber partition are respectively inserted into the chamber positioning groove and the door positioning groove.

[0019] By adopting the above technical solution, the positioning grooves in the mixing compartment and the door of the mixing compartment provide dedicated insertion and positioning positions for the compartment partitions. When the mixing compartment door is closed, the top of the compartment partition can be inserted into the positioning groove, and the side of the compartment partition can be inserted into the door positioning groove. This stabilizes and limits the installation orientation of the compartment partitions, reducing shaking or displacement of the partitions during mixing operations. This improves the accuracy and stability of the compartment partition assembly, thereby ensuring the airtightness of the mixed compartment after separation.

[0020] Optionally, the bottom of the mixing chamber is provided with a discharge port, both ends of which extend to the sides of the mixing chamber. The dry mortar mixed by the mixing host is transported to the storage silo for receiving through the discharge port. The bottom of the mixing chamber is provided with several chamber reinforcing ribs, all of which span the discharge port. The mixing chamber is provided with a discharge door, which is used to open and close the discharge port. The discharge door is located between two adjacent chamber reinforcing ribs.

[0021] By adopting the above technical solution, the discharge port, which extends through the bottom of the mixing silo to both ends, reaches the sides of the silo, expanding the coverage of the discharge channel. This allows the mixed dry mortar to be smoothly transported to the storage silo through the discharge port, improving the smoothness and thoroughness of the discharge. Several reinforcing ribs are installed across the discharge port, enhancing the structural strength of the bottom of the mixing silo, reducing the impact of the discharge port on the overall structural stability of the mixing silo, and extending the service life of the mixing silo.

[0022] A dry mortar production process is implemented using the aforementioned dry mortar production equipment.

[0023] Optionally, the dry mortar production process includes the following steps: S1. After the required batch of dry mortar has been produced, shut down the dry mortar production equipment. S2. Open the mixing chamber door, pull the mixing spindle out of the mixing chamber, and after the first base is separated from the main base, rotate the third base to move the mixing spindle and the first base away from the mixing chamber. S3. Clean the mixing spindle and mixing blades that have slid and rotated to the outside of the mixing chamber.

[0024] By adopting the above technical solution, the dry mortar production equipment can perform a shutdown operation after completing the corresponding batch production, providing safe and stable operating conditions for subsequent cleaning operations. Opening the mixing chamber door and pulling the mixing spindle out of the mixing chamber, with the first base detached from the main unit base and the third base rotated, allows the mixing spindle and mixing blades to be smoothly moved outside the mixing chamber. This provides a spacious cleaning operation area for the mixing spindle and mixing blades, facilitating the thorough cleaning of adhering dry mortar materials. This helps reduce material residue on the mixing spindle and mixing blades, thereby reducing the impact of dried and clumped residue on subsequent production batches, improving the efficiency and convenience of cleaning operations, and enabling the dry mortar production equipment to quickly complete material changeover and cleaning preparations, better adapting to production scenarios involving multiple product types, small batches, and frequent material changes.

[0025] In summary, this application includes at least one of the following beneficial technical effects: The raw material conveyor stably transports the dry mortar raw materials to be mixed to the mixing host, while the storage silo stably receives the dry mortar after mixing by the host, ensuring a continuous and smooth dry mortar production process. The mixing chamber door allows for opening and closing of the side of the mixing chamber, providing operating space for the mixing spindle to move out of the mixing chamber. The host base slides horizontally with the first base, and the second base rotates with the third base, enabling the mixing spindle to move out of the mixing chamber and adjust its angle. Once the mixing spindle and mixing blades are moved outside the mixing chamber, cleaning operations are facilitated, reducing the residue of dry mortar materials on the mixing spindle and mixing blades. This helps prevent residual materials from drying and clumping, thus reducing the impact of residual materials on the quality of subsequent production batches, improving the turnover efficiency of the dry mortar production equipment. This allows the dry mortar production equipment to adapt to production scenarios involving multiple categories, small batches, and frequent material changes, broadening the equipment's applicability.

[0036] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0037] Example 1: This application discloses a dry mortar production equipment. (Refer to...) Figure 1 The dry mortar production equipment includes a raw material conveyor 1, a mixing host 2, and a storage silo 3. The raw material conveyor 1 transports the dry mortar raw materials to be mixed from the bottom of the equipment to the mixing host 2 at the top, ensuring the continuity and stability of the raw material transport. The type of raw material conveyor 1 can be an existing bucket conveyor or a screw conveyor. The dry mortar raw materials to be mixed include cement sand and additives, wherein the additives need to be modified and added according to the performance requirements of the dry mortar produced in this field. The mixing host 2 is located between the storage silo 3 and the raw material conveyor 1. The storage silo 3 receives the dry mortar mixed by the mixing host 2 from the bottom, stably storing the finished material and thus ensuring the smooth connection of the production process.

[0038] Reference Figure 2 and Figure 3 The mixing unit 2 includes a main unit base 41, a mixing chamber 5, a mixing chamber door 6, a mixing main shaft 7, a first base 42, a second base 43, and a third base 44. The main unit base 41 is fixedly installed on the second-level platform of the equipment, and the mixing chamber 5 is fixedly installed on the main unit base 41. The mixing chamber 5 has a mixing compartment 501 inside, which provides space for mixing the dry mortar raw materials to be mixed. (Refer to...) Figure 4 The mixing chamber door 6 is used to open and close the front and rear sides of the mixing chamber 501. There is one mixing chamber door 6 at each end to provide operating space when the mixing spindle 7 needs to be removed. The bottom of the mixing chamber door 6 is rotatably fitted to the bottom of the mixing chamber body 5. The bottom of the mixing chamber door 6 and the bottom of the mixing chamber body 5 have overlapping tongue and groove joints, and the edges of the tongue and groove joints have rounded corners to facilitate the rotation of the mixing chamber door 6, thereby reducing the fall of dry mortar raw materials when the mixing chamber door 6 is closed.

[0039] Reference Figure 3 The mixing compartment door 6 is equipped with two door locking levers 61, which are rotatably engaged on the left and right sides of the mixing compartment door 6, respectively. (See reference...) Figure 4 A locking handwheel 62 is threaded through the end of the door locking rod 61 away from the mixing door 6, and the locking handwheel 62 can be threaded into the top of the mixing chamber body 5 after passing through the door locking rod 61. Furthermore, after passing through the door locking rod 61, the locking handwheel 62, through its own annular protrusion 621, presses the door locking rod 61 against the mixing chamber body 5, thereby ensuring the mixing door 6 is tightly closed. By limiting the closed state of the mixing door 6 with the door locking rod 61, and by using the locking handwheel 62 to lock and unlock the door locking rod 61, it is beneficial to prevent the mixing door 6 from accidentally opening during production, thereby improving the stability and convenience of opening and closing the mixing door 6.

[0040] Reference Figure 3 The inner wall of the mixing chamber 501 is provided with sealing ribs 51, which are adapted to the shape of the inner side of the mixing chamber door 6. When the mixing chamber door 6 is closed, the sealing ribs 51 fit against the inner side of the mixing chamber door 6, which can improve the sealing effect between the mixing chamber door 6 and the mixing chamber 501, reduce material leakage from gaps, and reduce dust pollution in the production area. At the same time, the sealing ribs 51 also help to enhance the structural strength of the side wall of the mixing chamber 501 and improve the overall structural stability of the mixing chamber body 5.

[0041] Reference Figure 3 The mixing chamber 501 has four compartment partitions 52 inside, divided into two groups. Each group of partitions corresponds to a mixing spindle 7, and the production equipment has a total of two groups of mixing spindles 7. One group of partitions 52 is joined to the other group of partitions 52 by overlapping tongue and groove joints, dividing the mixing chamber 501 into three sub-compartments distributed along the width of the mixing chamber body 5. The partitions 52 are detachably installed on the mixing chamber body 5 for selection and installation as needed, and are disassembled when the mixing spindle 7 needs maintenance and cleaning after the mixing chamber door 6 is opened. For details, refer to... Figure 3 and Figure 4 The mixing chamber 5 has a chamber positioning groove 502 on its top, which extends horizontally through the thickness of the mixing chamber 5. The mixing chamber door 6 has a door positioning groove 601 that extends through the height of the mixing chamber door 6. When the mixing chamber door 6 is closed, the top and side of the chamber partition 52, which is placed inside the mixing chamber 501, are respectively inserted into and adapted to the chamber positioning groove 502 and the door positioning groove 601, thereby accurately defining the installation position of the chamber partition 52, reducing the shaking and displacement of the chamber partition 52 during operation, and improving the stability of the assembly of the chamber partition 52.

[0042] Reference Figure 6 The compartment partition 52 includes a partition body 521 and a movable insert plate 522. The partition body 521 has a movable slot, and the movable insert plate 522 is inserted into the movable slot. After the movable insert plate 522 is inserted into the movable slot, it is installed on the compartment partition 52 by two extended bolts. Furthermore, referring to... Figure 5 After the movable insert plate 522 is installed on the compartment partition plate 52, the inner wall of the movable slot and the movable insert plate 522 are closely fitted to the mixing spindle 7 so that the materials that need to be separated in each sub-compartment are not easily mixed with each other.

[0043] Reference Figure 5 The mixing chamber 5 has main shaft clearance grooves 503 on its left and right sides. These grooves are adapted to the mixing main shaft 7, providing clearance for its removal and repositioning. Furthermore, when the mixing chamber door 6 is closed, its left and right sides cover the main shaft clearance grooves 503 to reduce material leakage. (Refer to...) Figure 7 and Figure 8 The mixing spindle 7 has a first base 42, a second base 43, and a third base 44 at its two ends, respectively. The first base 42 and the second base 43 are horizontally slidably fitted to the main unit base 41 via slide rails, and the third base 44 is rotatably fitted to the second base 43. The mixing spindle 7 is arranged along the width direction of the mixing chamber 5, and its two ends are rotatably fitted to the first base 42 and the third base 44, respectively. The rotation axis of the second base 43 is at an angle to the rotation axis of the mixing spindle 7, and in this embodiment, the rotation axis of the second base 43 is perpendicular to the rotation axis of the mixing spindle 7. Several mixing blades 71 are coaxially fixedly mounted on the mixing spindle 7 to facilitate mixing of raw materials with another set of mixing spindles 7.

[0044] Reference Figure 3 The main unit base 41 is rotatably fitted with a power gear 45, which has a power input. In this embodiment, the power gear 45 is preferably driven by a motor (not shown in the figure). A main shaft gear 72 is coaxially fixedly mounted on the mixing main shaft 7. The bottom of the main shaft gear 72 meshes with the top of the power gear 45, so that the main shaft gear 72 and the mixing main shaft 7 can be rotated by the power gear 45. When the mixing main shaft 7 is moved, the interference effect on the power gear 45 is reduced, thereby ensuring the operational stability of the mixing operation and the ease of disassembly and assembly of the mixing main shaft 7.

[0045] Reference Figure 9A discharge port 504 is provided through the bottom of the mixing silo 5, with both ends of the discharge port 504 extending to the sides of the mixing silo 5. The mixed dry mortar is conveyed downwards to the storage silo 3 through the discharge port 504. Several silo body reinforcing ribs 53 are welded and fixedly connected to the bottom of the mixing silo 5. The silo body reinforcing ribs 53 are all arranged across the discharge port 504 along the thickness direction of the mixing silo 5 to enhance the structural strength of the bottom of the mixing silo 5. Several discharge silo doors 54 are rotatably connected to the mixing silo 5 via a silo door pivot. The discharge silo doors 54 are used to open and close the discharge port 504. The discharge silo doors 54 are located between two adjacent silo body reinforcing ribs 53, which can stably control the discharge process and ensure smooth and reliable discharge operation. A silo door gear 541 is coaxially fixedly connected to the end of the silo door pivot, so that other gears driven by a motor can be rotated to open each discharge silo door 54 when needed.

[0046] The implementation principle of the dry mortar production equipment in Embodiment 1 of this application is as follows: During the production stage, the raw material conveyor 1 transports raw materials to the mixing host 2. The mixing spindle 7 drives the mixing blades 71 to rotate and complete the mixing of multiple components. The finished product is transported to the storage silo 3 through the discharge port 504. During the cleaning and maintenance stage, the equipment is shut down, the mixing silo door 6 is opened, and the mixing spindle 7 is pulled out of the mixing silo 501. After the first base 42 is separated from the host base 41, the third base 44 is rotated to move the mixing spindle 7 to the outside of the mixing silo 501, so that the mixing spindle 7 and the mixing blades 71 can be cleaned. The silo partition 52 can be flexibly disassembled to separate the mixing silo 501, which can adapt to the needs of multi-category, small-batch production. The overall equipment is easy to clean, improving turnover efficiency and applicability.

[0047] Example 2: This application discloses a dry mortar production process, implemented using the dry mortar production equipment of Example 1 above, including the following steps: S1. After the required batch of dry mortar is produced, the dry mortar production equipment is shut down, and the operation of the raw material conveyor 1 and the mixing host 2 is stopped. This provides safe and stable working conditions for subsequent cleaning operations and reduces the safety hazards of cleaning operations while the equipment is running.

[0048] S2. Open the mixing chamber door 6 and pull the mixing spindle 7 out of the mixing chamber 501. After the first base 42 separates from the main unit base 41 to avoid the mixing chamber body 5, rotate the third base 44 to move the mixing spindle 7 and the first base 42 away from the mixing chamber 501. This allows the mixing spindle 7 and the mixing blades 71 to be moved smoothly to the outside of the mixing chamber 501, providing a spacious operating space for cleaning operations.

[0049] S3. Cleaning the mixing spindle 7 and mixing blades 71 that have slid and rotated to the outside of the mixing chamber 501 can thoroughly clean the attached dry mortar material and reduce the material residue on the surface of the mixing spindle 7 and mixing blades 71.

[0050] The implementation principle of the dry mortar production process in Embodiment 2 of this application is as follows: After the production of a single batch of dry mortar is completed, a shutdown operation is performed. Using the opening and closing structure of the mixing chamber door 6 and the sliding and rotating structure of the mixing main shaft 7, the mixing main shaft 7 and mixing blades 71 are moved out of the mixing chamber 501 for cleaning, simplifying the cleaning process. Cleaning reduces material residue, which helps prevent residual material from drying and caking, contaminating subsequent production batches, thereby improving product quality stability. After cleaning, the mixing main shaft 7 is reset and the mixing chamber door 6 is closed, allowing for rapid commencement of the next batch of production. This enables the dry mortar production equipment to better adapt to production scenarios involving multiple categories, small batches, and frequent material changes, improving equipment turnover efficiency and production adaptability.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
