Description

Technical Field

[0001] This utility model relates to the field of mortar production equipment, specifically a drying device for dry powder mortar production. Background Technology

[0002] In the field of building materials, dry-mix mortar is a commonly used building material, and its performance and quality have a significant impact on the quality of construction projects. During the production and processing of dry-mix mortar, drying equipment is required to remove the moisture it contains. Drying is a crucial step that directly affects the degree of dryness and quality stability of the dry-mix mortar.

[0003] During the drying process, the dry mortar needs to be continuously stirred to ensure uniform heating and improve the drying effect. However, current stirring technologies often suffer from incomplete or inadequate stirring, which can lead to localized overheating or undercooling of the dry mortar during drying. Localized overheating may cause certain components in the dry mortar to undergo chemical reactions, affecting its performance; while localized undercooling will result in insufficient drying of the dry mortar, leaving excessive residual moisture, thus affecting its quality and performance. Utility Model Content

[0004] The purpose of this utility model is to provide a drying device for dry powder mortar production to solve the above-mentioned technical problems.

[0005] Technical solution: A drying device for dry powder mortar production, comprising a drying cylinder and a stirring assembly, characterized in that:

[0006] The drying cylinder has a hollow cavity inside, and a drying cylinder is rotatably installed inside the hollow cavity;

[0007] The stirring assembly is rotatably disposed inside the drying cylinder and includes a servo motor, an upper rotating shaft, and a stirring cylinder. The servo motor is disposed outside the drying cylinder and drives the upper rotating shaft to rotate. The upper rotating shaft passes through the drying cylinder and extends into the drying cylinder, with one end fixedly connected to the stirring cylinder. Multiple stirring rods are slidably disposed on the outer wall of the stirring cylinder, and stirring blades are connected to the end of each stirring rod away from the stirring cylinder.

[0008] In one specific implementation, a cylindrical cam is installed inside the drying cylinder, and the stirring cylinder is sleeved outside the cylindrical cam. The outer wall of the cylindrical cam is provided with spiral grooves at equal intervals that are adapted to the stirring rod, and the end of the stirring rod away from the stirring blade is inserted into the spiral groove.

[0009] The above technical solution enables the mixing rod to oscillate back and forth along the inner wall of the spiral groove while rotating and mixing, increasing the diversity of mixing and improving the drying effect of dry powder mortar.

[0010] In one specific implementation, an electric heating plate for heating the hollow cavity is installed on the inner wall of the drying cylinder, and the inner wall of the drying cylinder is also covered with heat-insulating material.

[0011] The above technical solution can heat the inside of the drying drum to achieve the drying effect.

[0012] In one specific implementation, the drying cylinder is a cylindrical groove structure with the groove opening facing upwards, and the interior of the drying cylinder is equipped with a drive assembly for driving the drying cylinder to rotate.

[0013] The above technical solution facilitates the feeding and discharging of dry mortar.

[0014] In one specific implementation, the drive assembly includes a drive motor, a drive gear, and a gear ring. The drive motor is mounted on the outer wall of the drying cylinder, the drive gear ring is rotatably mounted inside the drying cylinder and rotatably connected to the output end of the drive motor, and the gear ring is fixedly mounted on the outer wall of the drying cylinder and meshes with the drive gear ring.

[0015] Through the above technical solution, the drive motor causes the drive gear to rotate, which in turn drives the gear ring to rotate, thereby causing the drying cylinder to rotate. When the drying cylinder rotates to the point where its slot faces downwards and is directly opposite the bottom wall of the drying cylinder, all the dry mortar can be discharged.

[0016] In one specific implementation scheme, the drying cylinder is provided with a feed inlet at the top and a discharge outlet at the bottom, both of which are connected to the drying cylinder. A support bracket is also installed on the outer wall of the drying cylinder for supporting it.

[0017] With the above technical solution, the feed inlet can feed material into the interior of the drying cylinder, and in the initial state, the groove on the upper part of the drying cylinder corresponds to the feed inlet, and the undried dry mortar will enter the interior of the drying cylinder through the feed inlet.

[0018] In one specific implementation, a lower rotating shaft is rotatably installed inside the drying cylinder, the lower rotating shaft is horizontally arranged along the length of the drying cylinder, and a feeding auger is provided on the outer wall of the lower rotating shaft.

[0019] The above technical solution can continuously convey the dried dry mortar to the discharge port, thereby realizing the automatic feeding of the dried dry mortar.

[0020] In one specific implementation, a transmission assembly is further included for the rotation of the upper and lower rotating shafts. The transmission assembly includes a drive shaft, two driving bevel gears, and two driven bevel gears, wherein:

[0021] The drive shaft is fixedly connected to the drive end of the servo motor;

[0022] The active bevel gear is sleeved on the drive shaft and corresponds to the upper rotating shaft and the lower rotating shaft respectively;

[0023] The driven bevel gears are respectively sleeved on the upper rotating shaft and the lower rotating shaft, and the driven bevel gears and the driving bevel gears mesh with each other.

[0024] Through the above technical solution, when the drive motor rotates, it drives the driven bevel gear that meshes with the active bevel gear to rotate, thereby realizing the synchronous rotation of the upper and lower rotating shafts.

[0025] Beneficial effects: This utility model uses a servo motor to drive the upper rotating shaft, which in turn drives the mixing drum to rotate inside the drying drum. This allows for the mixing and drying of the dry mortar powder placed inside the drying drum, ensuring that the dry mortar powder is fully and evenly stirred during the drying process, thus avoiding local overheating or overcooling. At the same time, as the mixing drum drives the mixing rod and mixing blades to rotate, the mixing rod can move along the spiral groove opened on the outer wall of the cylindrical cam, causing the mixing rod to oscillate back and forth along the inner wall of the spiral groove. This increases the diversity of mixing and improves the drying effect of the dry mortar powder. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-4 A drying device for dry powder mortar production, comprising,

[0033] Drying cylinder 1 has a hollow cavity inside, and drying cylinder 14 is rotatably mounted in the hollow cavity;

[0034] The stirring component is rotatably disposed inside the drying cylinder 1 and located inside the drying cylinder 14;

[0035] The stirring assembly includes an upper rotating shaft 5 rotatably mounted on the side wall of the drying cylinder 1. A servo motor 7 for driving the upper rotating shaft 5 to rotate is provided outside the drying cylinder 1. A stirring cylinder 17 is fixedly connected to one end of the upper rotating shaft 5 extending into the interior of the drying cylinder 1. Multiple stirring rods 18 are slidably arranged on the outer wall of the stirring cylinder 17. A stirring blade 19 is connected to one end of the stirring rod 18 extending to the outside of the stirring cylinder 17.

[0036] Specifically, the upper rotating shaft 5 is driven by the servo motor 7 to rotate the mixing drum 17 inside the drying drum 14, which can stir and dry the dry powder mortar put into the drying drum 14.

[0037] See Figures 2-4 A cylindrical cam 20 is installed inside the drying cylinder 14, and a stirring cylinder 17 is fitted outside the cylindrical cam 20. Spiral grooves 21, corresponding to the number of stirring rods 18, are equally spaced on the outer wall of the cylindrical cam 20. One end of the stirring rod 18 extending into the stirring cylinder 17 is inserted into the spiral groove 21.

[0038] Specifically, the mixing drum 17 is driven to rotate by the upper rotating shaft 5. As the mixing drum 17 drives the mixing rod 18 and the mixing blade 19 to rotate, the mixing rod 18 will move along the spiral groove 21 opened on the outer wall of the cylindrical cam 20. This causes the mixing rod 18 and the mixing blade 19 to swing back and forth along the inner wall of the spiral groove 21 while rotating and mixing, increasing the diversity of mixing and improving the drying effect of dry powder mortar.

[0039] See Figure 3 The inner top wall of the drying cylinder 1 is equipped with an electric heating plate 13 for heating the hollow cavity, and the inner wall of the drying cylinder 1 is also provided with heat insulation material.

[0040] Specifically, the interior of the drying cylinder 1 can be heated by the electric heating plate 13. When the interior of the drying cylinder 1 is heated to a suitable temperature, the dry powder mortar entering the drying cylinder 1 can be dried.

[0041] See Figure 2 and Figure 3 The drying cylinder 14 has a cylindrical groove structure, and the groove opening of the drying cylinder 14 is set upward. The interior of the drying cylinder 1 is equipped with a drive assembly for driving the drying cylinder 14 to rotate.

[0042] Specifically, the dry powder mortar entering the drying cylinder 1 can be gathered by the set drying cylinder 14.

[0043] See Figures 2-3 The drive assembly includes a gear ring 15 fixedly mounted on the outer wall of the drying cylinder 14 and a drive gear 16 rotatably mounted inside the drying cylinder 1. The drive gear 16 meshes with the gear ring 15, and a drive motor 11 for driving the drive gear 16 to rotate is mounted on the outside of the drying cylinder 1.

[0044] Specifically, the drive motor 11 drives the drive gear 16 to rotate, which in turn drives the gear ring 15 to rotate, thereby driving the drying cylinder 14 to rotate. When the drying cylinder 14 rotates to the point where its slot faces downward and is directly opposite the inner bottom wall of the drying cylinder 1, the dry mortar that has entered it can be completely discharged.

[0045] See Figures 1-2 The top of the drying cylinder 1 is provided with a feed inlet 2 and the bottom of the drying cylinder 1 is provided with a discharge outlet 3. Both the feed inlet 2 and the discharge outlet 3 are connected to the drying cylinder 1. A bracket 4 for supporting the drying cylinder 1 is also installed on the outer wall of the drying cylinder 1.

[0046] Specifically, material can be fed into the interior of the drying cylinder 1 through the feed inlet 2, and in the initial state, the groove at the top of the drying cylinder 14 corresponds to the feed inlet 2, so that the undried dry powder mortar is transported into the interior of the drying cylinder 14 through the feed inlet 2.

[0047] See Figures 1-2 A lower rotating shaft 6 is rotatably installed inside the drying cylinder 1. The lower rotating shaft 6 is horizontally arranged along the length of the drying cylinder 1. A feeding auger 12 extends axially from the outer wall of the lower rotating shaft 6. A transmission assembly for driving the upper rotating shaft 5 and the lower rotating shaft 6 to rotate is provided on the side wall of the drying cylinder 1.

[0048] Specifically, when the lower rotating shaft 6 rotates, it drives the feeding auger 12 to rotate inside the drying cylinder 1. After the dry powder mortar is dried, the drying cylinder 14 can discharge the dried dry powder mortar to the lower part of the drying cylinder 1. The rotation of the feeding auger 12 can continuously convey the dried dry powder mortar to the discharge port 3, thereby achieving the effect of automatic feeding of the dried dry powder mortar.

[0049] See Figure 1 The transmission assembly includes a drive shaft 8, two active bevel gears 9 and two driven bevel gears 10. The drive shaft 8 is vertically arranged on the side of the drying cylinder 1 and is connected to the output end of the servo motor 7. The two active bevel gears 9 are sleeved on the drive shaft 8 and correspond to the positions of the upper rotating shaft 5 and the lower rotating shaft 6, respectively. The two driven bevel gears 10 are sleeved on the upper rotating shaft 5 and the lower rotating shaft 6, respectively. The active bevel gears 9 and the driven bevel gears 10 mesh with each other.

[0050] Specifically, the servo motor 7 causes the drive shaft 8 to rotate. During the rotation of the drive shaft 8, the drive shaft 8 drives the active bevel gear 9, which is fixed coaxially with it, to rotate. The active bevel gear 9 drives the driven bevel gear 10, which meshes with it, to rotate. The driven bevel gear 10 can drive the upper rotating shaft 5 and the lower rotating shaft 6 to rotate, thereby achieving the effect of synchronous rotation of the upper rotating shaft 5 and the lower rotating shaft 6.

[0051] It should be noted that in order for the servo motor 7 to drive the lower rotating shaft 6 or the upper rotating shaft 5 independently, the driving bevel gear 9 can be connected to the drive shaft 8 through an electromagnetic clutch. The electromagnetic clutch has an engaged state that can transmit torque and an disengaged state that cannot transmit torque. When the electromagnetic clutch is engaged, the drive shaft 8 transmits torque to the driving bevel gear 9 through the electromagnetic clutch. When the electromagnetic clutch is disengaged, the drive shaft 8 cannot transmit torque to the driving bevel gear 9 through the electromagnetic clutch.

[0052] Working principle: Undried dry mortar is fed into the drying cylinder 14 through the feed inlet 2. An external power supply powers the heating plate 13, which heats the inside of the drying cylinder 14 to a high temperature. The dry mortar entering the drying cylinder 14 gradually dries under this high temperature. To accelerate the drying process, a servo motor 7 drives the upper rotating shaft 5 to rotate the mixing drum 17 inside the drying cylinder 14. This stirs and dries the dry mortar fed into the drying cylinder 14. During the rotation of the mixing drum 17, the mixing rod 18 and the mixing blade 19 move along the cylinder... The spiral groove 21 on the outer wall of the cam 20 moves, causing the stirring rod 18 and stirring blade 19 to oscillate back and forth along the inner wall of the spiral groove 21 while rotating and stirring, increasing the diversity of stirring and improving the drying effect of dry mortar. The lower rotating shaft 6 can drive the feeding auger 12 to rotate inside the drying cylinder 1. After the dry mortar is dried, the drying cylinder 14 can discharge the dried dry mortar to the lower part of the drying cylinder 1. The rotation of the feeding auger 12 can continuously convey the dried dry mortar to the discharge port 3, thereby achieving the effect of automatic feeding of the dried dry mortar.

[0053] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
